Japanese Unexamined Patent Publication No. 2003-675

By the way, when warm moxibustion stimulation is performed, it is known that by applying heat to a narrow range corresponding to a pot as described above, a blood circulation promoting effect and associated activation of the body are achieved. Therefore, it is preferable that the treated portion of the electric moxibustion device has a thin shape. In addition, in the treatment of warm moxibustion, the treatment portion is quickly heated, so that the treatment time can be shortened and burns and the like can be prevented.

On the other hand, if the treatment portion has a thin shape and an attempt is made to provide a heating element in the vicinity of the treatment portion, a small heating element must be used. When the heating element is small, it is difficult to transfer the heat required for the treatment to the treatment part, and there arises a problem that the treatment part cannot be heated quickly. In addition, when an attempt is made to increase the size of the heating element and quickly achieve heating to the treatment area, it is difficult to provide the heating element in the vicinity of the treatment area due to the thin shape of the treatment area, and heat is conducted to the treatment area. It will take time to do so, and there will be a problem that the treatment site cannot be heated quickly.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an electric moxibustion device capable of easily applying suitable heat.

An electric moxibustion device that solves the above-mentioned problems includes a case and a treatment portion attached to the case, and the treatment portion is recessed toward the tip portion and the tip portion and is provided on the case side. A treatment body having an opening accommodating portion and an extending portion in the accommodating portion that extends from the tip portion toward the case and has a surface parallel to the extending direction, and is arranged in the accommodating portion.

Includes a pressing member that presses in a direction intersecting with.
According to this configuration, the heating element is arranged in a direction in which the main surface of the heating element extends parallel to the direction extending from the tip of the treatment body toward the case, and is pressed in a direction intersecting the direction from the tip toward the case. .. The heat of the heating element is transferred from the main surface of the heating element to the tip of the treatment body via the extending portion, and the tip of the treatment body is heated. In the treatment section, the side surface of the heating element is arranged so as to face the tip of the treatment body. Therefore, the tip of the treatment body can be sized according to the thickness of the heating element and the extending portion. Therefore, as compared with the case where the heating element is arranged with the main surface of the heating element facing the tip of the treatment body, the heating element can be arranged closer to the tip of the treatment body while using a large heating element. .. Further, the tip portion of the treatment body can be tapered, and the tapered tip portion makes it easy to suitably apply heat to a desired portion. In addition, in this specification, "parallel" is intended not to intersect in the treatment part, and includes the state of two things which are parallel with a slight angle.

In the electric moxibustion device, the treatment portion is disposed between a first electrode plate disposed between the heating element and the extending portion, and between the heating element and the pressing member. It is preferable to have a second electrode plate.
According to this configuration, the pressing member presses the second electrode plate, the heating element, and the first electrode plate toward the surface of the extending portion. As a result, the first electrode plate and the second electrode plate are brought into close contact with both main surfaces of the heating element by the pressing member. Therefore, the electrical connection between the first electrode plate and the second electrode plate to the heating element is ensured.

In the above electric moxibustion device, a second extending portion having the extending portion as a first extending portion, extending from the tip portion toward the case, and having a facing surface facing the surface of the first extending portion. It is preferable that the pressing member has an extending portion and is arranged between the second extending portion and the second electrode plate.
According to this configuration, a heating element and a pressing member are arranged between the first extending portion and the second extending portion. Then, the heating element can be pressed against the first extending portion by the pressing member arranged between the second electrode plate and the second extending portion.

In the above electric moxibustion device, it is preferable that the treatment portion includes a heat conductive member which is flexible and is arranged between the heating element and the extending portion.
According to this configuration, the contact area between the main surface of the heating element and the heat conductive member and the contact area between the heat conductive member and the surface of the extending portion are as flexible as those of the heating element and the extending portion. It is larger than the contact area when low-quality materials are in direct contact with each other. By disposing the heat conductive member between the first electrode plate and the extending portion, the heat of the heating element is efficiently transferred to the extending portion via the first electrode plate and the heat conductive member. To. Therefore, the heat of the heating element is efficiently transferred to the extending portion and eventually to the tip portion of the treatment body.

In the electric moxibustion device, the contact area between the pressing member and the second electrode plate is preferably smaller than the contact area between the extending portion and the heat conductive member.
According to this configuration, heat transfer from the heating element to the pressing member is suppressed, and heat of the heating element is efficiently transferred to the tip of the treatment body via the first extending portion.

The electric moxibustion device is made of a heat insulating material, and is attached to the end portion of the treatment body on the case side to close the opening of the housing portion and supply power to the heating element. It is preferable to have a connecting member to which the ends of the are connected.
According to this configuration, the heat of the treatment body is reduced from being transferred to the connection substrate connected to the case and the heating element by the connecting member made of the heat insulating material.

In the electric moxibustion device, it is preferable that the connecting member is inserted into the housing portion of the treatment body and has an insertion portion whose tip surface is curved along the side surface of the heating element.
According to this configuration, the movement of the heating element is restricted by the insertion portion inserted into the accommodation portion of the treatment body. Therefore, the displacement of the heating element with respect to the extending portion is suppressed, and the tip portion of the treatment body is stably heated by the heat of the heating element.

According to the electric moxibustion device of the present invention, suitable heat can be easily applied.

The two extending portions 32 and 33 have facing surfaces 32a and 33a facing each other. These facing surfaces 32a and 33a are formed substantially parallel to the direction in which the extending portions 32 and 33 extend, that is, the direction from the tip portion 30a toward the case 10.

As shown in FIG. 4, the heating element 43 has a plate shape, and the outer shapes of the two main surfaces 43a and 43b in the thickness direction are, for example, circular. In this embodiment, the heating element 43 is a Positive Temperature coefficient (PTC) thermistor. The heating element 43 contains, for example _{, a ceramic element of a metal oxide semiconductor containing barium titanate (BaTIO 3} ) as a main component and silver (Ag) formed on the main surfaces 43a and 43b of the ceramic element as main components. It has an electrode.

The heat conductive member 41 has flexibility and is formed in a circular sheet shape. As the material of the heat conductive member 41, for example, an acrylic type, epoxy type, or silicon type heat radiating material can be used. As the heat conductive member 41, a gel-like heat radiating material or an epoxy-based or silicon-based adhesive having high heat conductivity may be used.

The electrode plate 42 has a connecting portion 42a and a lead portion 42b. The connecting portion 42a is formed in a circular thin plate shape. The outer diameter of the connecting portion 42a is set to be larger than the outer diameter of the heating element 43. The lead portion 42b is formed in a plate shape extending linearly from the end portion of the connecting portion 42a. The lead portion 42b is electrically connected to the wiring of the connection board 70 shown in FIG. 3B by, for example, solder. A protruding portion 42c is formed at the end of the connecting portion 42a.

The temperature sensor 46 (sensor body 46a) is, for example, a negative characteristic (NTC: Negative Temperature coefficient) thermistor. As shown in FIG. 3B, the lead wires 46b and 46c are electrically connected to the wiring of the connection board 70 by, for example, solder.

The heat conductive member 41, the electrode plate 42, the heating element 43, the electrode plate 44, and the pressing member 45 are arranged in this order with one extending portion 32 (first extending portion) and the other extending portion 33 (second extending portion). It is arranged between the extending portions). Therefore, the pressing member 45 presses the heat conductive member 41, the electrode plate 42, the heating element 43, and the electrode plate 44 toward the first extending portion 32. The facing surface 32a of the first extending portion 32 is a surface substantially parallel to the direction from the tip portion 30a of the treatment body 30 toward the case 10. Therefore, the pressing member 45 presses each member such as the heating element 43 in a direction substantially perpendicular to the facing surface 32a, that is, in a direction substantially orthogonal to the direction from the tip portion 30a of the treatment body 30 toward the case 10.

As shown in FIG. 7, the tip of the accommodating portion 31 is formed in a semicircular shape in a side view. The tip 31a of the accommodating portion 31 is formed larger than the shape of the heating element 43. As described above, the heating element 43 is formed in the shape of a circular plate. In a side view, the tip 31a of the accommodating portion 31 is formed in a semicircular shape having a radius larger than the radius of the heating element 43. In the present embodiment, the tip 31a of the accommodating portion 31 is formed to be substantially the same as the radius of the connecting portions 42a, 44a of the electrode plates 42, 44 described above. In the present embodiment, the side surface 43c of the heating element 43 is separated from the inner surface of the accommodating portion 31.

An engaging groove 31b forming a concave shape toward the tip portion 30a is formed at the tip end 31a of the accommodating portion 31. The protruding portion 44c of the electrode plate 44 described above is inserted into the engaging groove 31b. The engaging groove 31b and the protruding portion 44c engage with each other in the outer peripheral direction of the connecting portions 42a and 44a of the electrode plate 44. By this engagement, the rotation of the electrode plate 44 is restricted with respect to the treatment body 30 in the accommodating portion 31, and the lead portion 44b is positioned. Although not shown in FIG. 7, the protruding portion 42c of the electrode plate 42 described above is also inserted into the engaging groove 31b in the same manner. Then, the lead portion 42b of the electrode plate 42 is positioned by engaging the protruding portion 42c and the engaging groove 31b.

As shown in FIG. 5, a sensor accommodating portion 34 is formed in the treatment body 30. In the present embodiment, the sensor accommodating portion 34 is formed on the side opposite to the heating element 43 and the electrode plates 42 and 44 with respect to the extending portion 33. The sensor body 46a of the temperature sensor 46 is inserted into the sensor accommodating portion 34. As shown in FIG. 7, the sensor accommodating portion 34 is filled with, for example, gel-like silicon, and the heat of the treatment body 30 is transferred to the sensor main body 46a. The lead wires 46b and 46c of the temperature sensor 46 are separated by a heating element 43, a second electrode plate 44, and a second extending portion 33.

The connecting member 60 has an insertion portion 63 that is inserted into the accommodating portion 31 of the treatment body 30.
As shown in FIG. 9, in the connecting member 60, a protruding portion 64 is formed at the tip of the insertion portion 63. The protruding portion 64 is formed in a plate shape according to the thickness of the heating element 43 housed in the housing part 31. The thickness of the protruding portion 64 is set to a value that is thinner than the heating element 43 and does not interfere with the electrode plates 42 and 44. The protruding portion 64 projects toward the heating element 43, the upper and lower end portions 64a and 64b extend toward the treatment body 30, and the central portions of both end portions 64a and 64b are on the base end side (insertion portion 63 side). It is curved in a concave shape toward it. The surface (tip surface) 64c between the upper and lower ends 64a and 64b is formed in an arc shape having a curvature (radius) corresponding to the side surface 43c of the heating element 43.

As shown in FIG. 8, the above-mentioned insertion holes 61a and 61b are formed in the insertion portion 63. The lead portion 42b is inserted into the insertion hole 61a. The lead portion 44b is inserted into the insertion hole 61b. A groove portion 65 is formed in the insertion portion 63, and lead wires 46b and 46c are arranged in the groove portion 65. The lead wires 46b and 46c are separated from the lead portion 44b inserted into the insertion hole 61b at the insertion portion 63 of the connecting member 60. This prevents the second electrode plate 44 from electrically contacting the lead wires 46b and 46c of the temperature sensor 46.

Next, the operation of the above electric moxibustion device will be described.
As shown in FIG. 6, the treatment body 30 has extending portions 32 and 33 inside the accommodating portion 31 and extending from the tip portion 30a toward the case 10. The heat conductive member 41, the electrode plate 42, the heating element 43, the electrode plate 44, and the pressing member 45 are arranged in this order with one extending portion 32 (first extending portion) and the other extending portion 33 (second extending portion). It is arranged between the extending portions).

The pressing member 45 presses the heat conductive member 41, the electrode plate 42, the heating element 43, and the electrode plate 44 toward the extending portion 32. Therefore, the electrode plates 42 and 44 are in close contact with the electrodes formed on both main surfaces 43a and 43b of the heating element 43. As a result, the heating element 43 is energized via the electrode plates 42 and 44 to generate heat. Further, the pressing member 45 presses the heating element 43 toward the first extending portion 32. The heat of the heating element 43 is transferred to the first extending portion 32 via the first electrode plate 42 and the heat conductive member 41. The extending portion 32 extends from the tip portion 30a of the treatment body 30 and is separated from the inner side surface 30b of the treatment body 30. Therefore, heat is transferred from the extending portion 32 to the tip portion, and the tip portion 30a is heated.

The heating element 43 has a plate shape. The extending portion 32 extends from the tip portion 30a toward the case 10 and has a facing surface 32a substantially parallel to the extending direction thereof. Then, the heating element 43 is pressed toward the facing surface 32a of the extending portion 32. The heating element 43 is arranged substantially parallel to the direction from the tip portion 30a of the treatment body 30 toward the case 10. That is, the side surface 43c of the heating element 43 is arranged toward the tip portion 30a of the treatment body 30.

Therefore, the width of the treatment body 30 can be narrowed in the thickness direction of the heating element 43. Therefore, in the pressing direction of the heating element 43, that is, in the thickness direction of the heating element 43, the outer shape (width) of the treatment body 30 is made thinner than when the main surface of the heating element 43 is arranged toward the tip. Can be done. Therefore, the treatment body 30 can be tapered. Then, in the tapered treatment body 30, since the side surface 43c of the heating element 43 is arranged so as to face the tip portion 30a, the tip portion is more than the case where the main surface of the heating element 43 is arranged toward the tip portion. It can be approached to 30a.

Further, in the tapered treatment body 30, the distance from the tip of the treatment body 30 to the heating element 43 is shorter than in the case where the main surface of the heating element 43 is arranged toward the tip. That is, the heat of the heating element 43 is transmitted to the tip portion 30a of the treatment body 30 over a short distance. Therefore, the tip portion 30a of the treatment body 30 can be efficiently heated.

As shown in FIG. 4, in the present embodiment, the pressing member 45 is a wave washer. Therefore, the pressing member 45 partially contacts the second electrode plate 44 in the circumferential direction of the second electrode plate 44. Therefore, the contact area between the pressing member 45 and the second electrode plate 44 is small, and the heat transfer from the second electrode plate 44 to the pressing member 45 is small. Therefore, the heat of the heating element 43 is mainly transmitted to the first extending portion 32 which is in close contact with the pressing member 45.

In the present embodiment, the pressing member 45, which is a wave washer, contacts the second electrode plate 44 at equal angular intervals in the circumferential direction of the second electrode plate 44. That is, the pressing member 45 applies an even pressing force to the second electrode plate 44 in the circumferential direction of the second electrode plate 44. Therefore, the pressing of the second electrode plate 44 against the heating element 43 is uniform on the main surface of the heating element 43, and there is little bias in the circumferential direction. The same applies to the pressing of the heating element 43 against the first electrode plate 42.

As shown in FIG. 2, a connecting member 60 is attached to the end of the treatment body 30 on the case 10 side. The connecting member 60 is made of a heat insulating material. Therefore, the heat of the treatment body 30 is insulated by the connecting member 60, and it is difficult to transfer it to the case 10. Then, if the heat transferred from the treatment body 30 to the connecting member 60 is small, the temperature of the treatment body 30 can be preferably changed.

As described above, according to the present embodiment, the following effects are obtained.
(1) The electric moxibustion device has a case 10 and a treatment body 30 attached to the tip of the case 10. The treatment body 30 includes an accommodating portion 31 that opens to the case 10 side, and an extending portion 32 that is inside the accommodating portion 31 and has a facing surface 32a that extends from the tip portion 30a toward the case 10 and is substantially parallel to the extending direction thereof. ,have. The accommodating portion 31 accommodates a plate-shaped heating element 43 in which one main surface faces the facing surface 32a, and a pressing member 45 that presses the heating element 43 against the extending portion 32. To.

The heating element 43 is arranged substantially parallel to the direction in which the treatment body 30 extends from the tip portion 30a toward the case 10. Then, the heat of the heating element 43 is transferred from the main surface of the heating element 43 to the tip portion 30a of the treatment body 30 via the extending portion 32, and the tip portion 30a of the treatment body 30 is heated. In the treatment portion 20, the side surface 43c of the heating element 43 is arranged so as to face the tip portion 30a of the treatment body 30. Therefore, as compared with the case where the heating element 43 is arranged with the main surface 43a of the heating element 43 facing the tip portion 30a of the treatment body 30, a larger heating element 43 is used and the heating element 43 is placed at the tip portion of the treatment body 30. It can be arranged close to 30a. Further, by using the large heating element 43, it is possible to secure the amount of heat for heating the tip portion 30a of the treatment body 30. Then, the tip portion 30a of the treatment body 30 can be tapered, and the tapered tip portion 30a can easily apply heat to a desired portion such as an acupuncture point.

(2) In the treatment body 30, a flexible heat conductive member 41 is arranged between the first electrode plate 42 and the extending portion 32. Therefore, the contact area between the first electrode plate 42 and the heat conductive member 41 and the contact area between the heat conductive member 41 and the extending portion 32 are the contact area between the first electrode plate 42 and the extending portion 32. It becomes larger than the case where it is in direct contact with. Therefore, the heat of the heating element 43 is efficiently transferred to the extending portion 32. Therefore, the heat of the heating element 43 can be efficiently transferred to the tip portion 30a of the treatment body 30 via the extending portion 32.

(3) A first electrode plate 42 is arranged between the heating element 43 and the extending portion 32, and a second electrode plate 44 is arranged between the heating element 43 and the pressing member 45. The pressing member 45 presses the first electrode plate 42, the heating element 43, and the second electrode plate 44 toward the extending portion 32. As a result, the first electrode plate 42 and the second electrode plate 44 are in close contact with both main surfaces of the heating element 43, so that the first electrode plate 42 and the second electrode plate 44 are brought into close contact with each other with respect to the heating element 43. The electrical connection is secure. The heat conductive member 41 is arranged between the extending portion 32 and the first electrode plate 42. By the heat conductive member 41, the heat of the heating element 43 is efficiently transferred to the tip portion 30a of the treatment body 30 via the first electrode plate 42, the heat conductive member 41, and the extending portion 32.

(4) The treatment body 30 has a first extending portion 32 and a second extending portion 33 extending from the tip portion 30a toward the case 10, and the first extending portion 32 and the second extending portion 32 are extended. The unit 33 has facing surfaces 32a and 33a facing each other. The pressing member 45 is arranged between the second extending portion 33 and the second electrode plate 44. Therefore, the heating element 43 and the pressing member 45 are arranged between the first extending portion 32 and the second extending portion 33. Then, the heating element 43 can be pressed toward the first extending portion 32 by the pressing member 45 arranged between the heating element 43 and the second extending portion 33.

(5) At the tip portion 30a of the treatment body 30, the temperature sensor 46 is arranged in the direction opposite to the pressing direction of the heating element 43 with respect to the heating element 43. Therefore, it is difficult for the heat of the heating element 43 to be directly transferred to the temperature sensor 46, and the temperature of the tip portion 30a of the treatment body 30 can be measured.

(6) One end of a connection board made of a heat insulating material, which is attached to the end of the treatment body 30 on the case 10 side, closes the opening of the accommodating portion 31, and has a wiring pattern for supplying power to the heating element 43. It has a connected connecting member 60. The connecting member 60 is made of a heat insulating material. Therefore, the connecting member 60 can suppress the transfer of the heat of the treatment body 30 to the connecting substrate connected to the case 10 and the heating element 43. Then, if the heat transferred from the treatment body 30 to the connecting member 60 is small, the temperature of the treatment body 30 can be preferably changed.

(7) The pressing member 45 is, for example, a wave washer. Therefore, the contact area between the pressing member 45 and the electrode plate 44 is smaller than the contact area between the extending portion 32 and the electrode plate 42 (heat conductive member 41). Therefore, the heat transfer to the pressing member 45 can be suppressed, and the heat of the heating element 43 can be efficiently transferred to the extending portion 32 and eventually to the tip portion 30a of the treatment body 30.

(8) In the accommodating portion 31 of the treatment body 30, the heat conductive member 41, the electrode plate 42, the heating element 43, the electrode plate 44, and the pressing member 45 are arranged in a laminated state between the extending portions 32 and 33. ing.
