Vacuum cleaner front cover switching-on two-position spacing structure

Abstract

The present invention relates to a dust collector, in particular to a front-cover opening two-gear spacing structure of a vacuum dust collector, which solves the problem of a dust collecting box and the universalization of a dust collecting bag of the dust collector, and the problem is also that the front cover is easily damaged when screws are fastened in the production and assembling of the dust collector. The collector comprises a main body which is provided with a sucking fan arranged inside; caster wheels are arranged on the two sides of a main body; a sucking nozzle is communicated with the inner part of the main body by a hose and an expansion pipe; an upper-part shell, a lower-part shell, a front cover and a rear cover form the appearance of the main body; a dust collecting part is caved to the inner part of the main body; a fixing clip of the dust collecting bag is blocked on the front edge of the dust collecting part; and the dust collecting bag or the dust collecting box is arranged in the dust collecting part. The dust collector is characterized in that in order to lead the loading and unloading of the dust collecting box and the production and assembling of the dust collecting box to be convenient and not damage the front cover, the front cover and the rear cover of the main body are designed as that a convex shaft of a shaft rack is rotationally connected with an axle hole and the front cover and the rear cover of the main body are provided with a double spacing and a blocking boss of the front-cover opening two-gear spacing structure. The dust collector achieves the universality of the dust collecting device of the dust collector and increases the convenience of product assembling and use and the market competitiveness.

Description

technical field [0001] The invention relates to a vacuum cleaner, in particular to a two-stage limit structure for opening the front cover of the vacuum cleaner, which provides convenience for the screw-connected assembly of the upper cover and the taking out and putting in of the dust collecting box. Background technique [0002] A vacuum cleaner (Canister) is a household appliance that uses the powerful suction generated by a rotating fan motor to suck in dust or foreign matter that pollutes the ground or crevices and sucks the dust or foreign matter into the dust collecting device in the main body of the vacuum cleaner. [0003] Vacuum cleaners can generally be divided into upright and horizontal. In an upright vacuum cleaner, the main body that generates suction is integrally formed with the suction nozzle that sucks foreign matter from the ground, and both can rotate accordingly. In the upright vacuum cleaner, the main body and the suction nozzle are connected and comm...

AI Technical Summary

Problems solved by technology

[0018] The existing vacuum cleaner dust collection device uses a dust collection bag, so the dust collection bag can be inserted into the dust collection bag and fixed in the dust collection part when the opening angle of the front cover is small. If the opening angle of the front cover is small, the dust collection box cannot be put into the dust collection part, resulting in the use of the dust collection box and reducing the versatility of the product, which is not conducive to product sales and market competition. Therefore, the dust collection bag and the dust collection box should be used in vacuum For vacuum cleaners, the opening angle of the front cover above the dust collection part should be increased, but the front cover cannot be opened too large, because during the production and assembly of the vacuum cleaner, the fixing screw holes on both sides of the front cover are very close to the front cover, and it is easy to tighten the screws. To scratch the front cover, in view of the above two reasons, a two-speed limit structure for opening the front cover of the vacuum cleaner is proposed
