Example 1

Referring to fig. 1, the present embodiment provides a cleaning device 100, which is suitable for performing a cleaning action on a surface to be cleaned to achieve a cleaning effect. The surface to be cleaned can be the ground, the wall surface with different roughness degrees or the surface of an object to be cleaned, and the type of the surface to be cleaned is not particularly limited in the application.

The cleaning action can be a dust-absorbing action, a floor-mopping action, or a dust-absorbing and floor-mopping action simultaneously, so as to ensure the cleaning efficiency of the cleaning device 100.

The cleaning device 100 is installed with a main machine, and the main machine is suitable for generating negative pressure in the cleaning device 100, so that when the cleaning device 100 cleans a surface to be cleaned, dirt on the surface to be cleaned can enter the cleaning device 100 under the action of the negative pressure, and cleaning is achieved.

Specifically, the cleaning device 100 includes a housing 1, a cleaning member rotatably coupled to the housing 1, and a driving motor coupled to the cleaning member to drive the cleaning member to rotate. The shell 1 is provided with a bottom plate 13, an air inlet 11 is formed in the bottom plate 13, and the driving motor drives the cleaning piece to rotate, so that dirt on the surface to be cleaned can be separated from the surface to be cleaned under the rotating action of the cleaning piece, and enters the shell 1 from the air inlet 11, and the purpose of cleaning the surface to be cleaned is achieved. In this embodiment, the cleaning member is a roll brush.

Wherein, use the moving direction of cleaning device 100 as the place ahead, at least partial cleaning member sets up the front side at air intake 11, and the cleaning member rotates anticlockwise under driving motor's drive to make filth can enter into casing 1 from air intake 11 under the inertia effect, further improve cleaning device 100's cleaning efficiency.

The connection between the cleaning members and the drive motor includes, but is not limited to: the cleaning piece is provided with a cavity, the driving motor is arranged in the cavity, and an output shaft of the driving motor is fixedly connected with the connecting piece arranged in the cavity, so that the cleaning piece is driven to integrally rotate through the output shaft when the driving motor runs; or, the cleaning element and the driving motor are arranged in parallel, the cleaning element and the driving motor are connected through a transmission element, the transmission element is in gear transmission and the like, is in a conventional structure and the like, and is not limited specifically here.

As can be seen from the above, the surface to be cleaned may be the surface of the object to be cleaned. When the hardness of the object to be cleaned is large, it is hardly deformed by the negative pressure. However, when the object to be cleaned is a relatively soft object such as a carpet, a part of the object to be cleaned is sucked into the cleaning device 100 through the dust suction port of the cleaning device 100 under the action of negative pressure, which is likely to cause the blockage of the cleaning member; also, the object to be cleaned entering the interior of the cleaning device 100 reduces the airflow that can enter the interior of the cleaning device 100 from the dust suction port, which in turn causes the degree of vacuum inside the cleaning device 100 to be too high and makes the cleaning device 100 difficult to push.

Referring to fig. 2 and fig. 3, in order to solve the above technical problem, at least one notch 12 communicating with the air inlet 11 is further disposed on the bottom plate 13 of the housing 1, and the air flow can enter the housing 1 from the notch 12 and the air inlet 11. In order to prevent the notch 12 from scratching the surface of the object to be cleaned during the cleaning process of the cleaning device 100, the notch 12 has a first wall 121 and second walls 122 respectively disposed at two ends of the first wall 121, the bottom plate 13 has an end portion 131 disposed close to the cleaning member of the cleaning device 100, and the junction between the second wall 122 and the end portion 131 is smoothly transited. That is, the junction of the second wall 122 and the end 131 is rounded.

Meanwhile, the cleaning device 100 further comprises an adjusting member 2 connected with the bottom plate 13 and installed at the at least one notch 12, and at least a part of the adjusting member 2 can rotate relative to the notch 12 under the action of a driving force to cover or expose the notch 12, so as to adjust the flow rate of the air flow entering the housing 1.

In the present embodiment, two notches 12 are provided. In other embodiments, the number of the notches 12 may also be one, three or other, and is not specifically limited herein, depending on the actual situation.

Wherein, when adjusting part 2 covers breach 12, cleaning device 100 treats the cleaning object and cleans, and the part treats that cleaning object is because its self compliance, when entering into casing 1 from air intake 11 under the negative pressure effect, can block up partial air intake 11, then causes to enter into the inside air current reduction of casing 1 from air intake 11 to cause the inside vacuum degree of casing 1 great. At this moment, at least part regulating part 2 rotates under the effect of drive power to expose breach 12, inside the air current can get into casing 1 from breach 12, and then reduces the inside vacuum of casing 1, so that the object of treating that gets into casing 1 inside drops outside casing 1 under the inside and outside pressure differential effect of casing 1, prevents then that the object of treating to clean from taking place the condition that cleaning member of cleaning device 100 stops up, and is convenient for the user to promote cleaning device 100 and remove in order to carry out cleaning.

In the present embodiment, the adjusting member 2 is rotated toward the inside of the housing 1 by the driving force. The purpose of this is to: after the adjusting part 2 rotates towards the outside of the housing 1, the adjusting part contacts with the surface to be cleaned or the object to be cleaned, so that the friction force between the adjusting part and the surface to be cleaned or the object to be cleaned is increased in the subsequent cleaning work of the cleaning device 100, and the adjusting part 2 contacting with the surface to be cleaned or the object to be cleaned contacts with dirt firstly to push the dirt to move, so that the dirt cannot enter the housing 1 from the air inlet 11 under the negative pressure effect, and the cleaning efficiency of the cleaning device 100 is reduced.

In one embodiment, the driving force is a negative pressure. Accordingly, at least part of the adjusting member 2 is rotated relative to the notch 12 in the height direction of the housing 1 by the negative pressure to switch the adjusting member 2 between the initial state and the adjusting state. When the adjusting piece is in the initial state, at least part of the adjusting piece 2 is abutted with the bottom plate 13 so as to cover the notch 12; in the adjustment state, at least part of the adjustment member 2 is rotated towards the housing 1 such that the indentation 12 is exposed. The purpose of this is to: when the object to be cleaned does not enter the housing 1, if the adjusting member 2 does not cover the gap 12 and the gap 12 is exposed, the intensity of the negative pressure in the housing 1 is reduced, and the cleaning efficiency of the cleaning device 100 is further reduced.

The adjusting part 2 can be rotated in its entirety relative to the recess 12. At this time, the adjusting member 2 has a rotating end connected to the base plate 13, so that the rotating end is rotatably connected to the base plate 13. Also, since the regulating member 2 is rotated by the negative pressure, the weight of the regulating member 2 needs to be less than the force of the negative pressure generated when the cleaning object is sucked into the housing 1.

When the adjusting element 2 is in the initial state, part of the adjusting element 2 covers the gap 12. At this time, the volume of the adjuster 2 covering the notch 12 accounts for 90% or more of the total volume of the adjuster 2. When the regulating members 2 are in the regulating state, all the regulating members 2 are rotated toward the housing 1 to expose the notches 12, thereby regulating the degree of vacuum in the housing 1.

Alternatively, at least part of the adjusting member 2 is made of a deformable material to be deformed to rotate under the negative pressure, thereby switching between the initial state and the adjusting state. The deformable material may be rubber, silica gel, etc., and is not specifically limited herein, and is determined according to actual conditions.

In this case, the adjuster 2 includes a connection portion 21 connected to the base plate 13 and a deformation portion 22 connected to the connection portion 21. When the adjusting member 2 is in the initial state, at least part of the deformation portion 22 covers the notch 12. When the adjusting member 2 is deformed by the negative pressure, the deforming portion 22 covering the notch 12 is rotated toward the housing 1, and the notch 12 is exposed to adjust the vacuum degree in the housing 1.

Specifically, the deformation portion 22 has an avoiding groove 221 provided near the connection portion 21, and the avoiding groove 221 is adapted to rotate the deformation portion 22 toward the housing 1 when the deformation portion 22 is deformed. In this embodiment, the thickness of the avoiding groove 221 is smaller than the thickness of the other parts of the deformation portion 22, so that under the negative pressure of the deformation portion 22, the avoiding groove 221 is pressed by the other parts of the deformation portion 22 to be deformed, and the deformation portion 22 rotates toward the inside of the housing 1.

In order to prevent the adjusting member 2 from switching from the self-adjusting state to the initial state, the adjusting member 2 directly falls out of the housing 1 under the action of its own gravity, and cannot shield the notch 12 and interfere with the surface to be cleaned or the object to be cleaned, the adjusting member 2 further includes an abutting portion 23, and the abutting portion 23 is disposed on at least one side of the deformation portion 22. When the adjusting member 2 is in the initial state, the abutting portion 23 abuts against the inner side of the bottom plate 13 under the elastic force of the deformation portion 22, so as to prevent the adjusting member 2 from rotating from the notch 12 to a direction away from the inside of the housing 1 due to its own weight. Moreover, the abutting portion 23 can cause at least part of the deformation portion 22 to continue to cover the notch 12 when the adjusting member 2 is switched from the self-adjusting state to the initial state.

In order to simplify the manufacturing process, the abutting portion 23 and the deformation portion 22 are integrally formed, and the abutting portion 23 is formed by bending outward from one end of the deformation portion 22. A step 24 is formed between the contact portion 23 and the deformation portion 22, and the step 24 is adapted to allow the deformation portion 22 to be positioned in the notch 12 and the contact portion 23 to abut against the inner side of the bottom plate 13 when the adjuster 2 is in the initial state.

In order to further simplify the manufacturing process, the deformation portion 22, the abutting portion 23, and the connection portion 21 are integrally formed. That is, in the present embodiment, the adjusting member 2 is entirely made of a deformable material. The connecting portion 21 is provided with a plurality of connecting points on a side away from the deformation portion 22, and correspondingly, the bottom plate 13 is provided with a plurality of connecting holes engaged with the connecting points. And the whole adjusting piece 2 is injected into the connecting hole by an injection molding machine until the whole adjusting piece 2 is formed.

In another embodiment, the driving force is a mechanical force. The adjusting member 2 is rotatably connected to the bottom plate 13, and accordingly, the cleaning device 100 further comprises a driving member connected to the adjusting member 2, and the driving member drives the adjusting member 2 to rotate. At this time, the adjusting member 2 has a rotating end. Alternatively, the cleaning device 100 further comprises a rotating shaft connected with the bottom plate 13, and the adjusting member 2 is rotatably disposed on the rotating shaft.

The host is a negative pressure fan. Here, the cleaning apparatus 100 is the cleaning apparatus 100 in embodiment 1 described above.

It is obvious that the above described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments in the present invention, a person skilled in the art can make changes or changes in other different forms without creative work, and all should belong to the protection scope of the present invention.
