Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dust compression device for a vacuum cleaner.

Vacuum cleaners equipped with a compression plate that compresses the dust accumulated in the dust collection chamber have traditionally been used.
There are many cases where it is not utilized because it has to be operated consciously. This has the disadvantage that the filter is severely clogged and the ability to suck in dust is reduced.

For this reason, for example,
As stated in the publication, a dust compression mechanism that is linked to the attachment and detachment of the suction hose is installed, so that dust can be automatically compressed without being conscious when the suction hose is attached and detached every time cleaning is done. This is what I did. However, in this type of compression mechanism, the operating force for the compression mechanism is the force for inserting and removing the suction hose, and the operating force is larger than that for normal attaching and detaching the suction hose, and there is a risk that the operability may be reduced. Also, it is not clear whether there is one L-shaped actuating body that operates the compression plate or multiple pieces, but since the actuating body is located inside the dust collection chamber, if there is only one L-shaped actuating body, the compression plate will not move. The pressing operation becomes unstable, and if there are multiple actuating bodies, the dust accumulated in the dust collection chamber interferes with the operation, making the operation unstable.

This invention was made in view of the above points, and it is possible to perform dust compression unconsciously, but it is possible to perform the dust compression operation without being affected by the dust in the dust collection chamber. The purpose is to provide a dust compression device for vacuum cleaners with good performance.

This invention provides a vacuum cleaner body in which a compression plate for compressing dust is attached to a dust collection case so as to be able to reciprocate while being urged in the return direction, and a part of the dust collection case is urged in one direction so that a part of it is exposed to the outside. A protruding actuating body and a transmission mechanism are provided, and each time the vacuum cleaner body is placed in the storage case, the actuating body interferes with the storage case to operate, and the transmission mechanism transmits the operating force to the compression plate, so that it can be automatically operated after cleaning. Furthermore, by providing a clutch in the transmission mechanism, the compression plate can be operated manually regardless of the operation of the operating body.

An embodiment of the present invention will be described based on the drawings. Reference numeral 1 denotes a storage case with an open top, in which various accessories such as a suction port body 2, a suction hose 3, a connecting pipe 4, etc. are stored. The opening edge of the storage case 1 is integrally formed with a locking piece 7 that engages with a locking recess 6 formed at the rear of the bottom of the cleaner body 5, and a locking piece 7 formed at the front of the bottom of the cleaner body 5. A clamp 9 that engages with the locking claw 8 is rotatably attached while being biased in the engagement direction by a spring 10. The vacuum cleaner main body 5 is constructed by connecting an electric case 11 and a dust collection case 12 with a clamp 13. An electric blower 1 is installed in one electric case 11.
4, code reel 15, and this code reel 15
A gear 16 and a dust meter 17 are provided.

Next, the dust collection case 12 includes a front cover 18 attached to the front side, and this front cover 18
The locking pawl 8 and a cylindrical suction port 19 are formed in the holder. A net filter 21 and filters 22 and 23 are stored in the dust collection chamber 20 in order from coarse to fine mesh, and a bottom cover 24 is kept closed by a clamp 25 below the dust collection case 12. connected. Furthermore, a dust removal handle 26 is attached to the exhaust side of the dust collecting case 12 and rotates by receiving the rotational force of the cord reel 15 through the gear 16. moreover,
A compression plate 28 having a dust scraping piece 27 connected to the upper part of the net filter 21 is attached to the dust collecting case 12, and a push button 30 is biased upward by a spring 29.
It is connected to and can be moved up and down.

An actuating body 31 is attached to the dust collecting case 12 on the back side of the front cover 18 so as to be movable up and down. This actuating body 31 includes a frame portion 33 in which a large opening 32 is formed to avoid interference with the suction port 19, a projecting piece 34 projecting downward from the lower edge of the frame portion 33, and an upper edge of the frame portion 33. It consists of a drive rack 35 and a clutch release part 36 that protrude upward from the clutch. A slope 37 that slopes downward from the side is formed on the upper surface of the clutch release portion 36.
Further, the dust collection case 12 and the actuating body 31 are provided with springs 38 that urge the actuating body 31 downward.
Support pieces 39 and 40 are formed to receive the support.

Next, a support shaft 41 is installed in the upper part of the dust collection case 12 with left and right axes, and this support shaft 41
A transmission mechanism 43 is provided for transmitting the upward operating force of the actuating body 31 to a driven rack 42 integrally connected to the compression plate 28. That is, the gear 44 that meshes with the drive rack 35 is rotatably held on the support shaft 41 while being prevented from moving in the thrust direction, and the gear 45 that meshes with the driven rack 42 is held by the spring 46.
It is held movably in the thrust direction and the radial direction while being biased towards it. A clutch 50 is provided by forming teeth 49 that mesh with each other on opposing surfaces of cylinders 47 and 48 integrally formed on these gears 44 and 45. Furthermore, a disc 51 that interferes with the clutch release portion 36 is fixedly provided on the gear 45.

In such a configuration, the vacuum cleaner main body 5 is
In the state of use when placed on the floor 52 as shown in the figure,
The actuating body 31 slides downward under the force of the spring 38, and the protruding piece 34 protrudes from the lower part of the dust collecting case 18. After use, the accessories 2 to 4 are stored in the storage case 1, and the vacuum cleaner main body 5 is placed on the opening edge of the storage case 1. As a result, as shown in FIG.
1 is a gear 4 whose projecting piece 34 joins to the upper edge 53 of the storage case 1 and rises, and meshes with the drive rack 35.
4 and the gear 45 connected to the gear 44 by the clutch 50 are rotated clockwise, and the driven rack 42 is lowered together with the push button 30 and the compression plate 28. gear 4
5 has a larger diameter than the gear 44, the stroke of the compression plate 28 is amplified compared to the stroke of the actuating body 31. At this time, the dust scraping piece 27 scrapes off dust adhering to the net filter 21. The locking recess 6 of the vacuum cleaner body 5 is held by the locking piece 7, and the locking claw 8
When engaged with the clamp 9, the actuating body 31 is in a fully raised position as shown in FIG. Slide it sideways as shown in Figure 5b. That is, clutch 5
0 is automatically cut off, and the compression plate 28 is raised together with the push button 30 and the driven rack 42 by the force of the spring 29 while rotating the gear 45 counterclockwise. Thereby, it is possible to press the push button 30 regardless of the operation of the actuating body 31 to perform an operation of compressing the internal dust using the compression plate 28.

Therefore, the internal space expands and the filter 2
The clogging of Nos. 1, 22, and 23 is also alleviated, and the dust collection ability is increased.

Since this invention is configured as described above, the operating body is operated every time the vacuum cleaner body is placed in the storage case after use, and the operating force is transmitted to the compression plate to automatically compress the dirt. In addition, since the actuator that operates the compression plate is installed outside the dust collection case, the actuator is not affected by the dust accumulated in the dust collection chamber, improving operability. By disengaging the clutch provided in the mechanism, the compression plate can be repeatedly operated in the compression direction regardless of the operation of the actuating body, resulting in effects such as always being able to obtain a good dust suction effect. It has the following.
