Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of dust collectors, and particularly relates to a press automatic opening device and a handheld dust collector. BACKGROUND

[0002] Since the traditional handheld dust collector is connected between the suction nozzle and the dust collecting box through threads, when more garbage and sundries are sucked into the dust collecting box, the suction nozzle needs to be unscrewed, the garbage and sundries are poured out, and then the suction nozzle is screwed onto the dust collecting box, so that the cleaning speed of the garbage and sundries is slow. In order to improve the cleaning speed and convenience of the garbage and sundries, the inventor designs a dust collector, such as a press opening device and a vehicle-mounted dust collector (application number: 201921426470.9), which comprises a connecting piece, a hook and an elastic buckle. By pressing the elastic buckle, the hook on the connecting piece is released from the elastic buckle, so as to achieve the purpose of one-key press opening of the suction nozzle cover. Although the dust collector is faster and more convenient than the traditional dust collector in cleaning garbage and sundries, it still has the following defects:

[0003] (1) Directly pressing the elastic buckle can only release the elastic buckle from the hook on the suction nozzle cover. When the suction nozzle dust bin needs to be cleaned, the suction nozzle cover still needs to be manually rotated to form a certain angle between the suction nozzle cover and the suction nozzle dust bin, so that the garbage and sundries in the suction nozzle dust bin can be completely removed, causing inconvenience in use.

[0004] (2) The elastic buckle is protrudingly arranged on the surface of the suction nozzle dust bin, which not only affects the user's holding, but also increases the overall size of the dust collector, and affects the external beauty of the entire dust collector.

[0005] Therefore, the inventor designs a press device and a dust collector to solve the above problems. SUMMARY

[0006] The purpose of the present application is to provide a press automatic opening device which can automatically open the buckle without manual cooperation, thereby being convenient to use.

[0009] A press automatic opening device comprises a box body, a buckle is hingedly and elastically covered on the box body, a rotating support is hingedly arranged in the buckle, one end of the rotating support away from the buckle is buckled with the box body, and a pop-up button is movably abutted on the rotating support.

[0010] As an improvement of the automatic pop-up device by pressing, an inner support is fixed in the buckle mouth, the inner support is in elastic abutment with the box body through a pop-up assembly, and the rotating support passes through the inner support.

[0011] As an improvement of the automatic pop-up device by pressing, a buckle part extends radially inward at the opening of the box body, and the end of the rotating support is buckled with the buckle part.

[0013] As an improvement of the automatic pop-up device by pressing, the pop-up assembly includes two rotating plates and a pop-up torsional spring, the two rotating plates are fixed to the two free ends of the pop-up torsional spring and are in abutment with the inner support and the box body respectively.

[0014] As an improvement of the automatic pop-up device by pressing, the two rotating plates are V-shaped and symmetrically arranged, the pop-up torsional spring is M-shaped, the spiral part of the pop-up torsional spring corresponds to the ends of the two rotating plates and is connected to the inner support through a shaft.

[0015] As an improvement of the automatic pop-up device by pressing, the pop-up button passes through the side wall of the buckle mouth and extends into the buckle mouth, the pop-up button is inclined and in elastic abutment with the rotating support, and the pop-up button is located outside the inner support.

[0016] In order to achieve the above-mentioned another object, a technical solution adopted by the present application is:

[0017] A handheld dust collector, characterized in that it comprises the automatic pop-up device by pressing.
