Description

Technical Field

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

[0002] Most existing mobile cleaning devices use a roller brush as a sweeping actuator. The roller brush rolls to make the brush or bristles on its outer periphery contact the surface to be cleaned, thereby cleaning the dirt attached to the surface to be cleaned. Although the roller brush structure covers a relatively large cleaning area, since the mobile cleaning device relies on negative pressure suction to collect dirt, the arrangement of the roller brush also brings about the disadvantage of blocking the air path, which weakens the negative pressure suction to a certain extent.

[0003] To this end, the applicant disclosed in the Chinese utility model patent previously applied for with patent number CN202122959279.4 (authorization announcement number CN216776859U) "A floor brush module for a cleaning machine and a cleaning machine". The cleaning machine adopts a disc brush structure instead of the traditional roller brush. Since the rotation axis of the disc brush extends vertically, there will be a rotation gap between two adjacent disc brushes. This gap is conducive to the passage of airflow, which greatly solves the problem of weakening of negative pressure suction in existing cleaning machines. However, the size of the gap between the disc brushes is usually fixed. When some larger particles need to be cleaned, insufficient suction may occur or the particles may get stuck in the gap between the two disc brushes.

[0004] For this reason, further improvements need to be made to the existing cleaning machine. Summary of the invention

[0005] The first technical problem to be solved by the present invention is to provide a floor brush module for a cleaning machine in which a brush member can actively avoid large dust particles from entering the dust suction chamber from the inlet in response to the current status of the prior art.

[0006] The second technical problem to be solved by the present invention is to provide a cleaning machine with the above-mentioned floor brush module in view of the current status of the prior art.

[0007] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: a floor brush module for a cleaning machine, comprising:

[0008] A shell, wherein there is a dust suction chamber for collecting dirt and a guide channel for conveying the collected dirt to a downstream dust separation module, and the dust suction chamber has an inlet located at the front side of the shell, and the inlet, the dust suction chamber and the guide channel are arranged in sequence along the flow direction of the fluid;

[0009] The movable seat extends along the left-right direction of the shell and is arranged to be deflected relative to the shell so that both ends thereof can swing forward and backward relative to the shell;

[0010] a brush head assembly, arranged on the movable seat, having brush members respectively connected to two ends of the movable seat, each of the brush members being located in the dust suction chamber and arranged to rotate relative to the surface to be cleaned so as to sweep the surface to be cleaned, and a rotation axis of each of the brush members extending vertically, and one of the two brush members can drive the corresponding end of the movable seat to deflect backward under pressure to move away from the inlet; and

[0011] The elastic member acts on the movable seat to make it always have a tendency to reset and swing.

[0012] There are many ways to achieve dust suction on the surface to be cleaned. Preferably, the front side of the shell has a base, and a gap is left between the bottom of the base and the surface to be cleaned to form a dust suction chamber.

[0013] In order to ensure the rotation of the brush member, preferably, the brush head assembly further comprises a driving mechanism, the driving mechanism is arranged on the moving seat, and a power output end of the driving mechanism is connected to the brush member.

[0014] In order to avoid the whole brush head assembly stopping due to power obstruction of a single brush, preferably, the driving mechanism has two drivers, each of which is arranged at the two ends of the movable base and the output shaft extends downward, and each brush is assembled on the output shaft of the corresponding driver.

[0015] In order to facilitate the swinging of the movable seat, preferably, the base is provided with two vertically through-arranged guide slots along the thickness direction at the position corresponding to the movable seat, each of the guide slots extends along the front-to-back direction, and the two ends of the movable seat can be respectively constrained in the corresponding guide slots so as to move forward and backward.

[0016] There are many ways to achieve the swing of the movable seat, preferably in the form of rotation, that is, the middle position of the movable seat can be rotatably connected to the upper side of the base and the rotation center is located between the two guide slots.

[0017] Specifically, the bottoms of both ends of the movable seat are provided with guide parts, and when the movable seat is in a deflected state, the guide parts at both ends thereof are slidably matched with the corresponding guide slots.

[0018] The guide part can be realized in different ways. Preferably, both ends of the movable seat have through holes for the output shaft of the driver to pass downward, and the guide part is an annular wall extending downward from the outer edge of the corresponding through hole. In this way, the design of the guide part, on the one hand, the annular wall plate design can prevent the output shaft of the driver from contacting the fluid to a certain extent, and prevent dust particles from getting stuck in the gap between the brushes, and protect the connection between the driver and the brush; on the other hand, the annular wall is a core component of the guide, which has high strength and slides more smoothly in the guide groove.

[0019] Specifically, an upwardly extending shaft is provided between the two guide notches, and a rotating sleeve sleeved outside the shaft is correspondingly provided at the middle of the movable seat.

[0020] Preferably, the elastic member is a torsion spring sleeved outside the rotating sleeve.

[0021] In order to ensure the cleaning effect, preferably, there are two movable seats and they are arranged at intervals in the length direction of the base, and each of the movable seats is provided with a brush head assembly.

[0022] In order to ensure that negative pressure is provided in the dust suction chamber, preferably, the guide channel has a suction port connected to the dust suction chamber of the shell, and the suction port is opened at the rear side of the dust suction chamber and is located between the two movable seats. With such a suction port arrangement, the swing of the movable seat can not only avoid the inlet, but also form a guiding posture in the dust suction chamber under its own swing, guiding the dust particles at the inlet to the suction port, avoiding leaving a cleaning dead corner, and achieving a better cleaning effect.

[0023] Specifically, each of the movable seats is arranged obliquely from the front to the back, from the outer end away from the suction port to the inner end adjacent to the suction port, so that each brush member in the dust suction chamber is arranged in a V-shape with the opening facing forward.

[0024] In order to further solve the above-mentioned second technical problem, the technical solution adopted by the present invention is: a cleaning machine, having the above-mentioned floor brush module, and also including a dust separation module and a fan module, the floor brush module, the dust separation module and the fan module are arranged in sequence along the flow direction of the fluid, and the outlet end of the floor brush module is the exhaust port of the shell.

[0025] Preferably, the cleaning machine is a floor scrubber or a vacuum cleaner.

[0026] Compared with the prior art, the advantage of the present invention is that in the floor brush module for the cleaning machine, since the movable seat inside the shell can be deflected relative to the shell so that its two ends can swing back and forth relative to the shell, when larger particles are encountered at the inlet and dust collection is obstructed, the brush members arranged 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, thereby providing sufficient entry space for large particles and avoiding the situation where dust particles are stuck in the gap between the two brush members.

[0034] The present invention is further described in detail below with reference to the accompanying drawings.

[0035] like Figures 1 to 7 As shown, it is a preferred embodiment of the present invention. In this embodiment, in this embodiment, the floor brush module is suitable for a cleaning machine, and the cleaning machine mentioned here can be a floor scrubber or a vacuum cleaner. Taking the 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, the dust separation module 103 and the fan module 104 are arranged in sequence 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 specifically includes a housing 1, a movable seat 11, a brush head assembly and an elastic member 4. The housing 1 has a dust suction chamber 100 and a guide channel 10 inside, wherein the dust suction chamber 100 is used to collect dirt, and the dust separation module is used to transport the collected dirt to the downstream dust separation module 103, and the dust suction chamber 100 has an inlet 101 located at the front side of the housing 1, and the inlet 101, the dust suction chamber 100 and the 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 for large particles is performed by the moving seat 11. The moving seat 11 extends along the left and right directions of the shell 1 and is arranged to be deflected relative to the shell 1 so that both ends thereof can swing back and forth relative to the shell 1, and the brush head assembly is arranged on the moving seat 11, and has brushes 2 respectively connected to the two ends of the moving seat 11, each brush 2 is located in the dust suction chamber 100 and is arranged to rotate relative to the surface to be cleaned to sweep the surface to be cleaned, and the rotation axis of each brush 2 extends vertically, and one of the two brushes 2 can drive the corresponding end of the moving seat 11 to deflect backward under pressure to stay 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 also includes a driving mechanism 3, which is arranged on the moving seat 11, and its power output end is drivingly connected to the brush 2. The driving mechanism 3 in this embodiment has two drivers 30 . Each driver 30 is arranged at two ends of the moving seat 11 and has an output shaft extending downward. Each brush member 2 is assembled on the output shaft of the corresponding driver 30 .

[0038] In this embodiment, a base 12 is provided on the front side of the housing 1, and a gap is left between the bottom of the base 12 and the surface to be cleaned to form a dust suction chamber 100. In order to ensure that the brush member 2 can be converted into a deflection of the movable seat 11 after being pressed, the base 12 is provided with two vertically penetrating guide slots 13 arranged along the thickness direction at the position corresponding to the movable seat 11, each guide slot 13 extends along the front-back direction, and the two ends of the movable seat 11 can be respectively constrained in the corresponding guide slots 13 to move forward and backward. Specifically, the middle position of the movable seat 11 can be 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 seat 11, the bottom of both ends of the moving seat 11 is provided with guide parts. When the moving seat 11 is in a deflected state, the guide parts at both ends slide and match with the corresponding guide slots 13. Specifically, both ends of the moving seat 11 have through holes for the output shaft of the driver 30 to pass downward, and the guide parts are annular walls 112 extending downward from the outer edges of the corresponding through holes. There is an upwardly extending shaft 14 between the two guide slots 13, and a rotating sleeve 111 sleeved outside the shaft 14 is correspondingly provided in the middle of the moving seat 11.

[0040] In order to ensure that the movable seat 11 can automatically deflect and reset after the large particles of debris are removed, the elastic member 4 acts on the movable seat 11 so that it always has a tendency to reset and swing. Specifically, the elastic member 4 in this embodiment is a torsion spring sleeved outside the rotating sleeve 111.

[0041] In addition, there are two movable seats 11 in this embodiment and they are arranged at intervals in the length direction of the base 12, and each movable seat 11 is provided with a brush head assembly. The above-mentioned guide channel 10 has a suction port 102 connected to the dust suction chamber 100 of the shell 1, and the suction port 102 is opened on the rear side of the dust suction chamber 100 and is located between the two movable seats 11. And each movable seat 11 is arranged from the front to the back from the outer end away from the suction port 102 to the inner end adjacent to the suction port 102, so that each brush member 2 in the dust suction chamber 100 is arranged in a V-shaped shape with the opening facing forward as a whole. In this way, the design form of the movable seat 11 enables each brush member 2 to form a specific posture arrangement, and combined with the special arrangement position of the suction port 102, the swing of the movable seat 11 can not only play the role of avoiding the inlet 101, but also form a diversion posture in the dust suction chamber 100 under its own swinging action, and guide the dust particles at the inlet 101 to the suction port 102, avoiding leaving a cleaning dead corner, and having a better cleaning effect.
