Description of the Related Art Conventionally, in a centralized collection device having one main body of the dust collecting device, outlets installed in several parts of the house, and pipes connecting the outlets and the main body, the above-mentioned Each of the multiple outlets could be opened independently.

The problem that the invention aims to solve is that when one outlet is being used for cleaning, the lid of the other outlet can be opened and closed freely.
If several outlets are used at the same time, or if the lid is opened due to mischief by children, etc., the dust suction power decreases.
There were various problems such as uneven suction and dirt clogging in the pipes.

The present invention solves the above-mentioned drawbacks, and utilizes the fact that when any outlet is used, the inside of the pipe becomes negative pressure, and provides a mechanism for restricting the opening of the lid of other outlets. The present invention provides a dust removal device.

Means for Solving the Problems In order to solve these conventional drawbacks, the present invention consists of a dust removal device main body, a pipe line for transmitting the dust suction force, a cylindrical part for connecting a cleaning hose, and a cylindrical part of this cylindrical part. It has a lid that rotatably closes the front surface, and an insertion port connected to the pipe end, and the insertion port is displaced by negative pressure inside the cylindrical part, and the lid is rotated. and a displacement member that limits the movement of the lid, the displacement member being a pressure-sensitive bellows-like member linked to a handle for operating the lid, and when under negative pressure, the handle linked to the pressure-sensitive bellows-like member moves the lid. It is designed to adhere closely to the surface of the

Function: With this configuration, the handle of the lid of the receptacle that is not in use cannot be operated when the apparatus is in operation, so that the receptacle will not be opened inadvertently.

Example Examples thereof will be described below with reference to the drawings.

FIG. 1, FIG. 2, FIG. 3, and FIG. 4 schematically show the central storage device.

Reference numeral 1 denotes the main body of the dust removal device installed in one place indoors, and it is linked with an insertion port 5 fixed at any position on the floor 3 or wall 4 through a conduit 2 laid under the floor or in the wall. has been done.

As shown in FIG. 5, the insertion port 5 is constructed by fixing a front cover part 6 and a rear cover part 7 with screws 8 with the wall surface 4 in between. It is fixed to a stud (not shown) or the like. A cylindrical portion 9 into which a cleaning hose fits is formed integrally with the front cover portion 6, and a packing 10 is provided between the cylindrical portion 9 and the rear cover portion 7 to improve airtightness. .

Reference numeral 11 denotes a lid that closes the cylindrical portion 9, and is rotatable by a shaft 12 provided on the front cover portion 6.

13 is an airtight sealing material, which is pasted on the inner surface of the lid 11;
It works to maintain airtightness when the blockage occurs.

Reference numeral 14 denotes an elastic bellows-like member that protrudes from a hole 15 provided in the lid 11, communicates the inside with the cylindrical portion 9, and is formed integrally with the airtight sealing material 13 here.

A handle 16 is made up of a shaft passing through the hole 15 of the lid 11 and a locking portion 17 that abuts the airtight sealing material 13 on the inner surface of the lid 11, and is fixed to the tip of the bellows-like member 14.

When using the above dust collection device, select one of the insertion ports 5, hold the handle 16 protruding from the lid 11 as shown in FIG. 5 using the elastic force of the bellows-like member 14, and pull the lid toward you. 11 is rotated forward to open it, and the cleaning hose is inserted and fitted into the cylindrical portion 9.

When one outlet is used for cleaning, all the pipes 2 are in communication, so the inside of the cylindrical part 9 of the other outlet 5 becomes negative pressure. On the other hand, the bellows-like member 14 protruding from the hole 15 of the lid 11 communicates with the cylindrical portion 9 at its inside, so that when the inside of the cylindrical portion 9 becomes negative pressure, it is pushed by atmospheric pressure and the lid 1
Shrink it so that it is pulled inside 1. Therefore, the handle 16 attached to the tip of the bellows-like member 14 is attached to the sixth
As shown in the figure, it comes into contact with the surface of the lid 11 and cannot be easily grasped, making it impossible to open the lid 11. Since this receptacle 5 has the above-described structure, it is possible to prevent the lids of two or more receptacles from being opened at the same time, thereby preventing a reduction in dust suction power and consequent clogging with dust. Other embodiments are shown in FIG. 7 and below.

The embodiment shown in FIG. 7 is characterized by a lid 18 provided with a recess 19 into which a handle 16 is fitted. Here, when the inside of the cylinder part 9 is negative pressure -
However, in the above structure, when using other outlets, the handle 16
is stuck in the recess 19 of the lid 18 and cannot be pulled out.
Simultaneous use of the sockets can be reliably prevented. The embodiment of FIG. 8 is also shown when the inside of the cylinder part 9 is under negative pressure, but it has exactly the same effect as the former, and when the inside of the cylinder part 9 is under negative pressure, the handle 1
A rib 21 that follows the shape of the handle 16 is provided on the surface of the lid 20 that the handle 6 comes into contact with.

In this embodiment as well, it is impossible to operate the handle 16 when the inside of the cylindrical portion 9 is under negative pressure. The embodiment shown in FIG. 9 is an example in which the pressure inside the bellows-like member is equal to atmospheric pressure.

A through hole 23 and a groove 25 into which a spring 24 is inserted are provided in the lid 22, and a handle 26 is attached to the lid 22 by passing through the through hole 23. Handle 26
A locking portion 27 is provided inside the lid 22, and a bellows-like member 28 is stuck between the locking portion 27 and the lid 22 to isolate the cylindrical portion 9 from the outside air. When the dust collecting device is not in use, the handle 26 projects forward of the lid 22 due to the elastic force of the spring 24. When the other outlet is used for cleaning, the inside of the cylindrical part 9 becomes negative pressure and the atmospheric pressure acts to push the locking part 27, and if this is made larger than the elastic force of the spring 24, the handle 26 comes into contact with the surface of the lid 22, making it impossible to open the lid 22. Since this embodiment uses a soft spring 24, the movement of the handle 26 is smooth.The embodiment shown in FIG. This is based on the embodiment shown in FIG. 5, but takes into consideration the mounting position of the handle 16.

That is, the handle 16 attached to the lid 29 in the same manner as described above can be used when the bellows-like member 31 is contracted due to negative pressure inside the cylinder part 9.
The locking portion 17 of the handle 16 is in a position where it comes into contact with the inner surface of the cylindrical portion 9. FIG. 10 shows the case when the inside of the cylinder part 9 is under negative pressure, and as described above, the locking part 17 is in contact with the inner surface of the cylinder part 9, so that
Not only the handle 16 cannot be gripped, but also the lid 29 cannot be rotated, making it even more reliable to close the lid 29 when using other outlets. Note that even if the embodiments listed other than those shown in FIG. 5 are used as a basis, exactly the same effect can be obtained. Effects of the Invention As described above, the present invention has a dust collection device main body, a pipe line for transmitting dust suction force, a lid that rotatably closes the front surface of a cylindrical part for connecting a cleaning hose, and the pipe line It consists of a socket connected to the end, and responds by sensing the negative pressure inside the cylinder.
By displacing a displacement member that disables the use of the operating handle of the lid, it is possible to open the lid of another socket when one socket is in use. This makes it possible to prevent a decrease in dust suction power and dirt clogging due to simultaneous use of the outlets or accidental opening of the lid.
The purpose of the present invention is to provide a centralized dust collection device that is advantageous in terms of cost, such as being able to easily improve existing dust collection devices.

Also, the operating status of the device can be determined by the condition of the handle, which is very convenient.
