Description

TECHNICAL FIELD

[0001] The present application relates to the field of household mobile cleaning equipment, in particular to a floor brush module for a cleaning machine and the cleaning machine. BACKGROUND

[0002] Most of the existing mobile cleaning equipment uses a roller brush as a sweeping brush executive component. The outer periphery of the roller brush or the bristles are in contact with the surface to be cleaned through the rolling of the roller brush, so as to realize the cleaning of the dirt attached to the surface to be cleaned. Although the roller brush structure covers a relatively large cleaning area in cleaning, since the collection of dirt by the mobile cleaning equipment depends on the negative pressure suction, the arrangement of the roller brush also has the disadvantage of blocking the air path, which weakens the negative pressure suction to a certain extent.

[0003] Therefore, the applicant discloses a floor brush module for a cleaning machine and the cleaning machine in the prior application of patent number CN202122959279.4 (authorized publication number CN216776859U). The cleaning machine uses a disc brush structure instead of the traditional roller brush. Since the rotation axis of the disc brush is vertically extended, there will be a rotation gap between the adjacent two disc brushes, which is exactly beneficial for airflow to pass through, greatly solving the problem of weakening the negative pressure suction of the existing cleaning machine. However, the size of the gap between the disc brushes is usually fixed. When cleaning some larger particles, the suction may be insufficient or stuck in the gap between the two disc brushes.

[0004] Therefore, further improvement is needed for the existing cleaning machine. SUMMARY

[0005] The first technical problem to be solved by the present application is to provide a floor brush module for a cleaning machine, in which the brush can actively avoid large particles of dust from entering the dust collection cavity through the inlet.

[0006] The second technical problem to be solved by the present application is to provide a cleaning machine with the above-mentioned floor brush module.

[0016] There are various ways to achieve the swinging of the moving seat, and preferably, the form of rotation, that is, the middle position of the moving seat is rotatably connected to the upper side of the base and the rotation center is located between the two guide slots.

[0017] Specifically, the bottom of each of the two ends of the moving seat is provided with a guide portion, and when the moving seat is in the deflected state, the guide portions of the two ends of the moving seat are slidingly matched with the corresponding guide slots.

[0018] The guide part can be realized in different ways, preferably, the moving seat has a through hole through which the output shaft of the driver passes at each end, and the guide part is a ring wall extending downward from the outer edge of the corresponding through hole. In this way, the design of the ring wall can avoid the contact between the output shaft of the driver and the fluid to some extent, avoid the dust particles from being stuck in the gap between the brushes, and protect the connection between the driver and the brush.

[0019] Specifically, the two guide slots have an upward extending shaft between them, and the middle part of the moving seat is provided with a rotating sleeve outside the shaft.

[0026] Compared with the prior art, the advantages of the present invention are as follows: In the floor brush module for the cleaning machine, since the movable seat inside the housing can deflect relative to the housing, so that both ends of the movable seat can swing back and forth relative to the housing, when the inlet encounters large particles that obstruct the suction, the brushes set at both ends of the movable seat can trigger the movable seat under the action of external pressure and swing synchronously with the movable seat to move away from the inlet position. This provides sufficient space for large particles to enter and avoids the situation where dust particles get stuck in the gap between the two brushes. Attached Figure Description

[0034] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] like Figures 1 to 7 The diagram shows a preferred embodiment of the present invention. In this embodiment, the floor brush module is suitable for use in a cleaning machine, which can be a floor scrubber or a vacuum cleaner. Taking a floor scrubber as an example, in addition to the floor brush module, it also includes a dust separation module 103 and a fan module 104. The floor brush module, dust separation module 103 and fan module 104 are arranged sequentially along the flow direction of the fluid, and the outlet end of the floor brush module is the exhaust port 106 of the housing 1.

[0036] The floor brush module for the cleaning machine comprises a housing 1, a moving base 11, a brush head assembly and an elastic member 4. The housing 1 has a dust collection cavity 100 and a flow guide channel 10 inside. The dust collection cavity 100 is used to collect dirt, and a dust separation module is used to transport the collected dirt to a downstream dust separation module 103. The dust collection cavity 100 has an inlet 101 on the front side of the housing 1. The inlet 101, the dust collection cavity 100 and the flow guide channel 10 are arranged in sequence along the flow direction of the fluid.

[0037] In this embodiment, the avoidance action of the brush 2 to large particles is performed by the moving base 11. The moving base 11 extends along the left-right direction of the housing 1 and is arranged to be able to deflect relative to the housing 1, so that both ends of the moving base 11 can swing forward and backward relative to the housing 1. The brush head assembly is provided on the moving base 11 and has two brushes 2 connected to the two ends of the moving base 11 respectively. Each brush 2 is located in the dust collection cavity 100 and is arranged to rotate relative to the surface to be cleaned to sweep the surface to be cleaned. The rotation axis of each brush 2 extends vertically, and one of the two brushes 2 can drive the corresponding end of the moving base 11 to deflect backward under pressure to move away from the inlet 101. Of course, in order to ensure the sweeping effect of the brush 2 on the surface to be cleaned, the brush head assembly further comprises a driving mechanism 3 provided on the moving base 11, and the power output end of the driving mechanism 3 is drivingly connected with the brush 2. The driving mechanism 3 in this embodiment has two drivers 30, each arranged at the end of the moving base 11 and the output shaft extends downward, and each brush 2 is assembled on the output shaft of the corresponding driver 30.

[0038] In this embodiment, the housing 1 has a base 12 on the front side, and the base 12 has a space between the bottom and the surface to be cleaned to form the dust collection cavity 100. In order to ensure that the brush 2 can be converted into deflection of the moving base 11 after being pressed, the base 12 has two vertically arranged guide slots 13 in the thickness direction at the positions corresponding to the moving base 11, each guide slot 13 extends along the front-back direction, and the two ends of the moving base 11 are movably constrained in the corresponding guide slot 13. Specifically, the middle part of the moving base 11 is rotatably connected to the upper side of the base 12, and the rotation center is located between the two guide slots 13.

[0039] In order to ensure smooth deflection of the moving base 11, the bottom of each end of the moving base 11 is provided with a guide portion, and the two ends of the moving base 11 are in sliding fit with the corresponding guide slot 13 when the moving base 11 is in the deflected state. Specifically, each end of the moving base 11 has a through hole for the output shaft of the driver 30 to pass downward, and the guide portion is a ring wall 112 extending downward from the outer edge of the corresponding through hole. Between the two guide slots 13, there is an upwardly extending shaft 14, and the middle part of the moving base 11 is provided with a rotating sleeve 111 fitted outside the shaft 14.

[0040] In order to ensure that the large-particle impurities are removed, the elastic member 4 acts on the moving seat 11 to make it always have a tendency of resetting after the moving seat 11 is automatically deflected.

[0041] In addition, the moving seat 11 in the embodiment has two and is arranged at intervals in the length direction of the base 12, and each moving seat 11 is provided with a brush head assembly. The flow guide channel 10 has a suction port 102 communicating with the dust suction cavity 100 of the shell 1, which is arranged at the rear side of the dust suction cavity 100 and between the two moving seats 11. Each moving seat 11 is arranged from the front to the rear and from the outer end away from the suction port 102 to the inner end adjacent to the suction port 102, so that each brush piece 2 in the dust suction cavity 100 is arranged in a V shape with the opening facing forward. In this way, the design form of the moving seat 11 makes each brush piece 2 form a specific posture arrangement, and the special arrangement position of the suction port 102 makes the moving seat 11 not only avoid the inlet 101 by swinging, but also form a flow guide posture in the dust suction cavity 100 under the action of its own swing, guide the dust particles at the inlet 101 to the suction port 102, avoid leaving a cleaning dead angle, and improve the cleaning effect.

[0042] The "fluid communication" in the present application refers to the spatial position relationship between two components or parts (hereinafter referred to as the first part and the second part respectively), i.e. the fluid (gas, liquid or mixture of the two) can flow or / and be transported from the first part to the second part along the flow path, which can be directly connected between the first part and the second part, or indirectly connected between the first part and the second part through at least one third party, which can be a fluid passage such as a pipe, a channel, a conduit, a flow guide, a hole, a groove, etc., or a chamber allowing fluid to flow, or a combination thereof.
