[0003] Currently, during the use of floor scrubbers, as the internal components operate, the internal temperature of the floor scrubber rises, causing the internal components to operate at high temperatures for extended periods. This increases the wear and tear on the internal components during operation, reducing the lifespan and performance of the floor scrubber. Utility Model Content

[0017] Compared with the prior art, the technical solution of this utility model embodiment has the following beneficial effects:

[0018] The floor scrubber provided by this utility model features a heat dissipation duct between the cleaning component and the water absorption component. The air inlet of the heat dissipation duct faces the water absorption component, and the air outlet faces the cleaning component. This allows the air discharged from the water absorption component to flow onto the surface of the cleaning component, eliminating the need for additional heat dissipation devices.

[0028] It should be noted that the terms "surface" and "on" in this specification are used to describe the relative spatial position and are not limited to whether there is direct contact.

[0029] As described in the background section, existing floor scrubbing machines still have shortcomings. The reasons for these shortcomings are analyzed below:

[0030] Current floor scrubbers include: a cleaning component for cleaning a target area; a water suction component for expelling air from the water suction component through high-speed rotation to create a negative pressure space to absorb wastewater from the target area; and a housing that provides a cavity for housing the components.

[0031] The cleaning assembly includes a brush motor, a brush disc, and a clean water tank; the brush motor drives the brush disc to rotate, the brush disc is connected to the brush motor, the brush disc has a pipe inside, and the pipe is connected to the clean water tank.

[0032] During the use of a floor scrubber, as the internal components operate, the temperature inside the scrubber rises, causing the cleaning components to operate at high temperatures for extended periods. This increases wear and tear on the cleaning components, reduces the lifespan of the floor scrubber, and diminishes its performance.

[0033] Currently, cooling fans are installed inside or at the bottom of the brush motor to cool it down. However, installing cooling fans increases the production cost of the floor scrubber.

[0034] To solve the above-mentioned technical problems, this utility model provides a floor scrubbing machine. By setting a heat dissipation air duct between the cleaning component and the water absorption component, with the air inlet of the heat dissipation air duct facing the water absorption component and the air outlet of the heat dissipation air duct facing the cleaning component, the air discharged by the water absorption component flows to the surface of the cleaning component. Without the need to add heat dissipation devices, the air discharged by the cleaning component is used to cool the surface of the cleaning component, thereby improving the service life and performance of the floor scrubbing machine and reducing the production cost of the floor scrubbing machine.

[0035] To make the above-mentioned objectives, features and beneficial effects of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0036] This utility model provides a floor scrubbing machine, comprising: a cleaning component for cleaning a target area; a water absorption component for absorbing wastewater from the target area; and a heat dissipation duct, which includes an air inlet and an air outlet, the air inlet facing the water absorption component and the air outlet facing the cleaning component, wherein the heat dissipation duct causes the air discharged by the water absorption component to flow to the surface of the cleaning component.

[0037] The floor scrubber works on the following principle: based on physical friction and water absorption mechanisms, the cleaning components stir up and remove dirt from the ground, while the water absorption components suck wastewater and dirt into the wastewater tank, achieving efficient cleaning of the ground.

[0038] Compared to existing technologies, the floor scrubber provided by this utility model has a heat dissipation duct between the cleaning component and the water absorption component. The air inlet of the heat dissipation duct faces the water absorption component, and the air outlet of the heat dissipation duct faces the cleaning component. This allows the air discharged from the water absorption component to flow to the surface of the cleaning component. There is no need to add heat dissipation devices. The air discharged from the cleaning component is used to cool the surface of the cleaning component, thereby improving the service life and performance of the floor scrubber and reducing the production cost of the floor scrubber.

[0039] Specifically, in combination Figures 1 to 7 The structure of the floor scrubber is described below:

[0040] Please refer to Figure 1The floor scrubber includes: a cleaning component 101 for cleaning a target area; a water absorption component 102 for discharging air from the water absorption component 102 through high-speed rotation to form a negative pressure space to absorb wastewater from the target area; and a heat dissipation duct 104, which includes an air inlet 1041 and an air outlet 1042, with the air inlet 1041 facing the water absorption component 102 and the air outlet 1042 facing the cleaning component 101. The heat dissipation duct 104 allows the air discharged from the water absorption component 102 to flow onto the surface of the cleaning component 101.

[0041] In some embodiments of the present invention, the floor scrubber further includes: a housing 100, wherein the cleaning component 101, the water absorption component 102, and the heat dissipation duct 104 are all located within the housing 100.

[0042] The floor scrubber includes a cleaning assembly 101. The cleaning assembly 101 is used to clean the floor.

[0043] In some embodiments of this utility model, the working principle of the cleaning component 101 is as follows: the clean water or cleaning agent in the clean water tank 105 is sprayed onto the ground. After the clean water or cleaning agent comes into contact with the dirt on the ground, the dirt is peeled off from the ground by the rotational friction of the brush plate.

[0044] like Figure 2 As shown, the cleaning assembly 101 includes a brush motor 1011. The brush motor 1011 is used to provide driving force for cleaning.

[0045] In some embodiments of this utility model, the cleaning assembly 101 further includes a brush disc 1012, and the brush motor 1011 is connected to the brush disc 1012.

[0046] In some embodiments of this utility model, the brush motor 1011 includes a rotating shaft 1013, the brush disk 1012 includes a slot 1014, and the rotating shaft 1013 is located in the slot 1014 to drive the brush disk 1012 to rotate at high speed.

[0047] Specifically, the bristles on the brush plate 1012 contact and agitate with the ground, effectively scrubbing the ground. The rotational friction of the brush plate can remove dirt and dust from the ground.

[0048] Because friction is generated when the brush plate 1012 contacts the ground, the brush motor 1011 has a high temperature during operation.

[0049] The floor scrubber also includes a water suction unit. The water suction unit is used to absorb the wastewater and dirt generated by the cleaning unit during floor cleaning.

[0050] In some embodiments of this utility model, the working principle of the water absorption component 102 is as follows: by rotating at high speed, the air inside the water absorption component is discharged to form a negative pressure space, and the suction cup sucks up the sewage in the target area under the action of vacuum suction, so as to suck the sewage and dirt on the ground into the sewage tank 106.

[0051] In some embodiments of this utility model, the water-absorbing component is located on the side of the cleaning component away from the ground, that is, the cleaning component 101 is located between the water-absorbing component 102 and the ground.

[0052] like Figure 3 As shown, the water absorption assembly 102 includes a water absorption motor 1021. The water absorption motor is used to create negative pressure to absorb sewage and waste.

[0053] In some embodiments of this utility model, the water absorption assembly 102 further includes: a suction cup 1023, a connecting pipe 1022, and a sewage tank 106; the suction cup 1023 is also connected to one end of the connecting pipe 1022, and the other end of the connecting pipe 1022 is connected to the sewage tank 106.

[0054] Specifically, the high-speed operation of the water suction motor 1021 generates a strong airflow, which makes the air pressure inside the sewage tank 106 lower than the outside air pressure, thus creating a negative pressure state, which draws sewage from inside into the sewage tank 106.

[0055] like Figure 4 As shown, the water suction motor 1021 includes: an impeller, the impeller having at least one exhaust port; and an air inlet 1041 facing the at least one exhaust port 1024.

[0056] The at least one exhaust vent is distributed around the impeller's axis of rotation; the heat dissipation duct 104 extends at least partially in a direction perpendicular to the axis of rotation.

[0057] The direction of the rotating shaft is the direction of the impeller's rotation center.

[0058] Specifically, when the suction switch is turned on, the suction motor 1021 starts working, driving the impeller to rotate at high speed and generating a high-speed airflow. This high-speed airflow causes the air pressure inside the sewage tank 106 to be lower than the outside air pressure, creating a negative pressure. At this time, the soft rubber strip on the suction squeegee contacts the ground, collecting and sucking in the sewage, which is then recycled back into the sewage tank 106 through the connecting pipe.

[0059] In other embodiments, the water suction motor 1021 also includes a heat dissipation vent, which is used to ventilate and dissipate heat from the water suction motor 1021 to prevent it from overheating and shutting down during operation, thus ensuring the stability of the operation of the water suction motor 1021.

[0060] Specifically, the water suction motor 1021 is integrated into the clean water tank 105, and the bottom of the clean water tank extends to below the water suction motor 1021.

[0061] The floor scrubber also includes a heat dissipation duct.

[0062] In some embodiments of this utility model, the working principle of the heat dissipation duct is as follows: by connecting the water suction motor 1021 and the brush motor 1011, during the operation of the floor scrubber, the air discharged by the water suction motor 1021 to form a negative pressure flows to the surface of the brush motor 1011, thereby cooling the brush motor 1011.

[0063] Specifically, the two ends of the heat dissipation duct along the airflow direction are an air inlet and an air outlet, respectively. In some embodiments of this utility model, the air inlet 1041 faces the water suction motor 1021, and the air outlet 1042 faces the brush motor 1011.

[0064] The cross-sectional area of ​​the air inlet 1041 is larger than that of the air outlet 1042, which increases the airflow velocity and thus improves the heat dissipation efficiency.

[0065] In some embodiments of this utility model, the cross-sectional area between the air inlet 1041 and the air outlet 1042 gradually decreases.

[0066] The diameter d1 of the air inlet 1041 is larger than the diameter d2 of the air outlet 1042. It should be noted that the diameter d1 of the air inlet 1041 corresponds to the cross-sectional area of ​​the air inlet 1041, and the diameter d2 of the air outlet 1042 corresponds to the cross-sectional area of ​​the air outlet 1042. This can increase the airflow velocity and thus improve the heat dissipation efficiency.

[0067] In other embodiments of this utility model, the air outlet 1042 of the heat dissipation duct 104 further includes a filter screen (not shown in the figure), which can filter out impurities in the airflow, prevent impurities from entering the cleaning component 101 and causing damage, and ensure the normal operation of the floor scrubber.

[0068] In some embodiments of this utility model, the floor scrubber further includes: a clean water tank 105, which is used to provide cleaning fluid to the cleaning assembly 101; a heat dissipation duct 104 is integrated on the clean water tank 105; and the clean water tank 105 is located between the heat dissipation duct 104 and the cleaning assembly 101.

[0069] The clean water tank 105 is integrated within the housing 100, and the clean water tank 100 and the housing 100 are not detachable.

[0070] The clean water tank 105 contains clean water or cleaning agent.

[0071] For example, such as Figure 5 As shown, the heat dissipation duct 104 is integrated on the clean water tank 105, the bottom of the clean water tank extends below the heat dissipation duct 104, and a battery is also located above the clean water tank 105.

[0072] For example, the heat dissipation duct 104 has an outer wall and an inner wall, the inner wall forming the heat dissipation duct 104, and a cold flow channel between the outer wall and the inner wall, the cold flow channel being connected to the clean water tank 105.

[0073] In some embodiments of this utility model, at least one of the outer wall and the inner wall is a curved surface, and the cold flow channel contains a cooling medium.

[0074] The cooling medium is the liquid in the clean water tank 105. The liquid in the clean water tank 105 is used to dissipate heat from the heat dissipation duct 104, thereby increasing the utilization rate of the device.

[0075] Specifically, the heat dissipation duct 104 is L-shaped, with the air inlet 1041 and air outlet 1042 located at the two ends of the L-shape, respectively.

[0076] In some embodiments of this utility model, the inner and outer walls of the heat dissipation duct 104 are made of metal materials; specifically, the inner and outer walls 104 are made of copper or aluminum. Copper or aluminum has good thermal conductivity, which can promptly dissipate heat from the heat dissipation duct 104 and allow the cooling medium in the cold flow channel to cool the air inside the heat dissipation duct 104.

[0077] In some embodiments, such as Figure 6 As shown, both the outer wall a and the inner wall b are curved surfaces.

[0078] It should be noted that, Figure 6 Only a portion of the "L"-shaped heat dissipation duct 104 is shown.

[0079] For example, a cold flow channel 1043 is located between the outer wall a and the inner wall b.

[0080] Both the outer wall a and the inner wall b are curved surfaces, making the corner portion of the "L"-shaped heat dissipation air duct 104 curved, reducing air resistance in the heat dissipation air duct 104, increasing the airflow speed, and thus improving heat dissipation efficiency.

[0081] In addition, both the outer wall a and the inner wall b are curved surfaces, which can increase the contact area between air and the heat dissipation duct 104, thereby improving the heat dissipation efficiency.

[0082] In other embodiments, such as Figure 7 As shown, the inner wall d is a curved surface, and the outer wall c is a straight surface.

[0083] It should be noted that, Figure 7 Only a portion of the "L"-shaped heat dissipation duct 204 is shown.

[0084] For example, a cold flow channel 2043 is located between the outer wall c and the inner wall d.

[0085] The outer wall c is a straight surface, which can increase the contact area between the heat dissipation duct 204 and the clean water tank 105, thereby improving the heat dissipation efficiency.

[0086] In addition, the inner walls d are all curved surfaces, which can increase the contact area between air and the heat dissipation duct 204, thereby improving the heat dissipation efficiency.

[0087] In other embodiments not illustrated, both the outer wall and the inner wall are straight surfaces.

[0088] In the above scheme, the heat dissipation duct has an outer wall and an inner wall, and the space between the outer wall and the inner wall is a cold flow channel, which can reduce the temperature inside the heat dissipation duct, so that the airflow is cooled when it flows through the heat dissipation duct, thereby improving the heat dissipation efficiency; in addition, the heat dissipation duct is integrated on the clear water tank, and the cold flow channel is connected to the clear water tank, so that the liquid in the clear water tank can be used to cool the heat dissipation duct, thereby improving the utilization rate of the component.

[0089] In summary, this utility model provides a heat dissipation duct between the cleaning component and the water absorption component. The air inlet of the heat dissipation duct faces the water absorption component, and the air outlet faces the cleaning component. This allows the air discharged from the water absorption component to flow onto the surface of the cleaning component. Without the need for additional heat dissipation devices, the air discharged from the cleaning component cools the surface of the cleaning component, thereby improving the service life and performance of the floor scrubber and reducing its production cost.

[0090] While the present invention has been disclosed above, it is not limited thereto.
