Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a vacuum cleaner equipped with a dust collection bag that can be thrown away together with collected dust, and a means for removing dust from the dust collection bag.

Conventional structure and its problems Traditionally, this type of dust removal device for a vacuum cleaner has a push button located in a position where the operation part to be pressed when removing dust can be operated from the outside of the vacuum cleaner body, and a push button built into the vacuum cleaner body. A diaphragm that is installed inside the dust collection box and applies vibration to the dust collection bag is integrally fitted through an opening provided in the dust collection box. Therefore, vibration of the same stroke as the stroke of pressing the push button can be applied to the dust collection bag, but since there are restrictions on the stroke of this push button, there is a limit to the dust removal effect. In addition, since the dust collection box cannot be freely attached to and removed from the main body of the vacuum cleaner, it is difficult to clean the dust collection box, making it inconvenient to use.

Purpose of the invention The present invention solves these conventional problems and provides a vacuum cleaner that improves the dust removal effect and improves usability by allowing the dust collection box to be attached and removed.

Structure of the invention The vacuum cleaner of the invention consists of a dust collection box that is built into the vacuum cleaner body so that it can be taken in and out, a dust collection bag that is detachably attached to the inside of the dust collection box, and a vibration and a push button that is operated from the outside of the outer shell of the vacuum cleaner body to operate the diaphragm, and the diaphragm is located inside the dust collection box, One end of the diaphragm is pivotally supported and biased so that it comes into close contact with the inner surface of the box, and an opening is formed in a part of the dust collection box so as to be closed midway from the pivot point of the diaphragm to the free end. On the other hand, a boss is provided vertically from the push button and faces the opening.

Therefore, even if the operating stroke of the push button is small, the diaphragm moves greatly due to so-called lever action, and the dust collection bag is vibrated accurately. Also, since the push button and dust collection box are structurally separated,
The dust collection box can be attached or detached as desired.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In the figure, 1 is a vacuum cleaner main body (hereinafter referred to as the main body) which has a built-in electric blower 2 for suction and can be divided into upper and lower parts, 3 is a filter device 4, and a dust collection bag 5 in which collected dust is thrown away. It is a removable dust collection box held by the main body 1, and is equipped with a vibration plate 6 for removing dust from the dust collection bag 5, and is disposed on the suction side of the electric blower 2. A dust collection bag 5 takeout opening is provided on the front surface of the dust collection box 3, and a dust collection bag support plate 7 is rotatably supported at the lower end of this opening. Reference numeral 8 denotes a pressing portion provided approximately at the center of the diaphragm 6, facing the opening 9 provided at the top of the dust collection box 3, and a gasket 10 is provided around the periphery to prevent air leakage from the opening 9. It is being A shaft portion 11 is protruded from one end of the diaphragm 6, and a coil spring 12 is attached to the shaft portion 11 for biasing the packing 10 in a direction that brings the packing 10 into close contact with the inner surface of the dust collection box 3 to perform air tightness. There is. The diaphragm 6 is the dust collection box 3
By fitting the shaft portion 11 into the bearing portion 13 of the holder, the shaft portion 11 is rotatably supported. By pressing the push button 14 whose operation surface is disposed on the outer shell of the main body 1, a boss 15 protruding from the approximate center of the push button 14 is pushed into the hole 16.
Then, the pressing portion 8 of the diaphragm 6 is pressed through the opening 9 of the dust collecting box 3, thereby applying vibration to the dust collecting bag 5 and removing dust therefrom. 17 is push button 13
18 is a plate spring that is bent to generate a metallic sound when the push button 13 is pressed; 19 is a front cover having a hose insertion port 20 and a handle 21, which fits closely to the dust collection bag outlet. It is equipped with a front cover abutment plate 23 having a lid rubber 22 attached to its outer periphery, and is rotatably supported on the lower front end of the main body 1.
It is adapted to be locked by a buckle 24. The electric blower 2 and the dust collection box 3 are separated by a partition wall 26 having a ventilation hole 25, and are in airtight contact with the partition wall 26 via a motor support rubber 27 and a partition gasket 28. 29 is a front wheel, 30 is a rear wheel, and 31 is a rest.

To explain the operation in the above configuration, the dust collection bag 5
Dust removal is performed by pressing the vibration plate 6 via the push button 14 and applying vibration to the dust collection bag 5. The greater the stroke and frequency of vibration applied to the dust collection bag 5, the greater the dust removal effect. However, one end of the diaphragm 6 is rotatably supported, and a pressing portion 8 is provided approximately at the center of the diaphragm 6.
By pressing , push button 1 is attached to the other end of the diaphragm 6.
Since it is possible to apply a vibration with a stroke larger than the stroke of pressing button 4,
The dust removal effect can also be improved by reducing the pressing stroke. Further, the pressing part 8 of the diaphragm 6 is located in the opening 9 of the dust collection box 3, the boss 15 of the push button 14 is located in the hole 16 of the main body 1, and the diaphragm 6 and the push button 14 are connected to the main body 1 and the dust collection box. By separating the dust collection box 3 near the contact surface of the dust collection box 3, the dust collection box 3 can be freely attached and detached. The dust collection box 3 can be attached or detached freely by standing the main body 1 upright using the rear wheels 30 and the rest 31, unlocking the buckle 24, and opening the front cover. In addition, since the diaphragm 6 can be attached to the dust collection box 3 simply by fitting the shaft portion 11 into the bearing portion 13,
In addition to being able to reduce man-hours and costs, the diaphragm 6 can be installed reliably and there is less rattling, so the tightness between the opening 9 of the dust collection box 3 and the seal 10 of the diaphragm 6 is also good. can be kept.

Effects of the Invention As is clear from the above embodiments, the vacuum cleaner of the present invention rotatably supports one end of the diaphragm. Even if the stroke of pressing the diaphragm is small, a large stroke of vibration can be applied to the other end of the diaphragm, and the dust removal effect can be improved. In addition, since the diaphragm only needs to be rotatably held in the dust collection box, the number of parts can be reduced, reducing man-hours and costs, and the diaphragm can be installed reliably to prevent rattling. Since it can be made small, it is also possible to maintain good tightness between the diaphragm and the opening.
