TECHNICAL FIELD

[0002] The base station type dust collection device is a kind of cleaning equipment that combines dust collector and dust collection base station, and the base station can realize the functions of dust collector storage, charging and dust box cleaning.When the dust collector is placed back to the base station and the dust collection function is started, the motor in the base station operates to generate suction force, and through the specially designed air duct, the garbage in the dust cup of the dust collector is sucked into the dust bag in the base station.At the same time, some base stations are also equipped with a filtering system to prevent dust from leaking into the surrounding environment during dust collection.

[0005] (2) In terms of power configuration, many dust collectors need to have a separate vacuum motor.This not only significantly increases the overall energy consumption of the dust collector, as each dust collector has an independent motor operating to consume power, the separate vacuum motor makes the structure of the dust collector more complex, and the installation, fixation and adaptation of the motor with other components of the dust collector need careful design and layout, which undoubtedly increases the design difficulty and manufacturing cost of the product;Moreover, once the independent vacuum motor fails, the entire motor system of the dust collector needs to be repaired or replaced, which is complex and time-consuming, seriously affecting the normal use of the dust collector, reducing the use reliability and stability of the equipment.

[0006] Therefore, according to the foregoing problems, we propose an innovative solution to improve to meet the market demand for efficient, energy-saving, simple and stable equipment. INVENTION CONTENTS

[0032] Specifically, when the dust collector 1 is placed on the dust collector 2, the gear 4 and the rack 5 are engaged, thereby driving the valve 6 to rotate, so that the position of the opening 602 on the valve 6 is adjusted, the vacuum motor 101 is switched from being communicated with the dust cup to being communicated with the air duct 201, and the dust collector 2 and the dust collector 1 share one vacuum motor 101, which not only simplifies the structure of the air duct 201 switching, but also reduces the design difficulty and manufacturing cost of the product.

[0033] In the existing base station, the vacuum motor 101 is usually separately arranged for dust collection, and the garbage in the dust cup is sucked out by negative pressure; the base station type dust collector device provided by the utility model shares one vacuum motor 101 for the dust collector 2 and the dust collector 1, and the vacuum motor 101 is arranged in the dust collector 1 (i.e. the main machine).

[0034] When dust collection is needed, the vacuum motor 101 generates negative pressure to suck the garbage from the outside into the dust cup; when dust collection is needed, the dust collector 1 is placed on the dust collector 2, and the gear 4 and the rack 5 transmission structure is used, the dust collector 1 is driven to move downward under the action of gravity, and rotates around the axis during the movement, and drives the valve 6 to rotate, and when the movement is in place, the opening 602 is aligned with the air duct 201 of the dust collector 2, and the negative pressure generated by the vacuum motor 101 can suck the garbage in the dust cup into the base station along the air duct 201.

[0041] Firstly, the gear 4 and the valve 6 can adopt an integrated structure. The valve 6 and the gear 4 are made of the same plastic material by using an injection molding process and are integrally formed in the same mold.
