[0044] In the related art, the cleaning brush head is arranged to guide the cleaning liquid into the inside of the roller brush, then heat the cleaning liquid in the inside of the roller brush, and then make the heated cleaning liquid flow from the water outlet in the inside of the roller brush to the outer surface of the roller brush to clean the ground. The cleaning brush head with heating function, the inside of the roller brush not only needs to be connected with the cleaning liquid, but also needs to be provided with an electric heating element, which inevitably requires high sealing performance of the cleaning brush head. Once the sealing performance is damaged, the roller brush will be damaged, and even the cleaning equipment will be damaged.

[0045] In view of this, the present disclosure provides a cleaning brush head, comprising: a liquid outlet configured to spray cleaning liquid; a roller brush disposed adjacent to the liquid outlet, the cleaning liquid sprayed from the liquid outlet at least partially sprayed to the outer surface of the roller brush; a heating device disposed in the roller brush, configured to heat the outer surface of the roller brush so as to heat the cleaning liquid sprayed to the outer surface of the roller brush; wherein the surface temperature of the heated outer surface of the roller brush is at least 20% higher than the temperature of the cleaning liquid before heating (or, the temperature of the heated cleaning liquid is at least 10% higher than the temperature of the cleaning liquid before heating).

[0046] The cleaning brush head provided by the present disclosure sets the heating device and sets the heating device in the roller brush, the liquid outlet can be set outside the roller brush, the cleaning liquid sprayed to the outer surface of the roller brush is heated by heating the roller brush, so that the state of the cleaning liquid being heated can be continuously guaranteed, the sealing requirement of the roller brush is not high, there is no risk of electric leakage, the cleaning performance of the cleaning brush head can be effectively improved, the cleaning efficiency can be improved, and the user experience can be improved.

[0047] The following will be described in detail in conjunction with the drawings of the specification: Figs. 1-3 illustrate optional embodiments of the present disclosure.

[0048] The cleaning brush head provided by the embodiments of the present disclosure comprises a shell 100, a rolling brush 200 and a connecting arm 300. The connecting arm 300 connects the shell 100 and the rolling brush 200. The shell 100 is used to accommodate structural components of the cleaning brush head, such as a driving assembly, a controller, a water supply pipeline, a water pump, an electromagnetic valve and the like. The shell 100 can also accommodate a clean water tank, a cleaning agent tank and the like. The driving assembly and the controller can control the rotation of the rolling brush 200. The water supply pipeline and the water pump are used to supply clean water or cleaning liquid to the rolling brush 200. The side wall of the shell 100 near the rolling brush 200 is provided with a plurality of liquid outlets 110, which are configured to spray cleaning liquid. The cleaning liquid can be clean water or a mixture of clean water and cleaning agent. At this time, the cleaning liquid is usually at room temperature, that is, not heated. The rolling brush 200 is arranged near the liquid outlet 110, and the rolling brush 200 has a gap with the liquid outlet 110. The cleaning liquid sprayed from the liquid outlet 110 is at least partially sprayed to the outer surface of the rolling brush 200, for example, the cleaning liquid can also be sprayed to the operation surface. A heating device 400 is arranged in the rolling brush 200, which is configured to heat the outer surface of the rolling brush 200 so as to heat the cleaning liquid sprayed to the outer surface of the rolling brush 200. The temperature of the heated cleaning liquid is at least 10% higher than that of the cleaning liquid before heating. For example, when the temperature of the cleaning liquid is 20-30 degrees, the temperature of the heated cleaning liquid is at least 22-33 degrees. Because the temperature of the cleaning liquid is increased, the cleaning active molecules in the cleaning liquid are more active. For example, the dirt that originally needs to stay for 10 seconds to remove can now be removed in 6 seconds or less, greatly improving the cleaning effect of the surface such as the ground and helping to improve the cleaning power of the operation surface and improve the cleaning efficiency.

[0049] In some embodiments, the surface temperature of the outer surface of the rolling brush 200 after heating is at least 20% higher than the temperature of the cleaning liquid before heating.

[0050] The inventor has conducted a large number of studies on the relationship between the temperature increase of clean water and the cleaning effect of the surface such as the ground. If the temperature increase of the liquid outlet of the heating device 400 is controlled to be more than 10% higher than the temperature of the added clean water, the cleaning power of hard surfaces such as ceramic tiles, wooden floors and glass can be increased by 15%-25%. If the temperature increase is too low, it is difficult to stimulate the activity of cleaning active molecules in the cleaning liquid, and the ideal cleaning power improvement effect cannot be achieved.

[0051] Similarly, if the temperature of the liquid discharged from the heating device 400 can be controlled to be more than 10% higher than the temperature of the cleaning agent added, the cleaning power for hard surfaces such as ceramic tiles, wooden floors, and glass can be increased by 25%-40%. If the temperature is too low, it is difficult to stimulate the activity of cleaning active molecules in the cleaning liquid, and the desired cleaning power cannot be achieved. For example, when the temperature of the cleaning agent added is normal temperature of 20-25 degrees, if the temperature of the liquid discharged from the heating device 400 is controlled to be more than 23-30 degrees, the cleaning liquid is used to clean various types of hard surfaces by cleaning equipment such as a scrubber, and the original 10 seconds required to remove stains can now be removed in 6 seconds or less, greatly improving the cleaning effect of the surface of the floor. In some embodiments, the cleaning brush head includes a water distribution plate 120, and the water distribution plate 120 is provided with a plurality of liquid outlets 110. In some embodiments, the water distribution plate 120 includes a first water distribution plate 121 and a second water distribution plate 122. The first water distribution plate 121 is located above the second water distribution plate 122 in the height direction of the shell. The first water distribution plate 121 has a first liquid outlet 111, and the second water distribution plate 122 has a second liquid outlet 112. After the water and the cleaning agent are mixed, the cleaning liquid is sprayed out of the first liquid outlet 111 and / or the second liquid outlet 112 under pressure and directly sprayed onto the outer surface of the roller brush 200. Since the outer surface of the roller brush 200 is in a heated state, its temperature is higher than that of the cleaning liquid at normal temperature. When the cleaning liquid is sprayed onto the outer surface of the roller brush 200, the cleaning liquid is heated, and due to the effect of heat, the cleaning active molecules in the cleaning liquid are more active, which can improve the cleaning power of the cleaning agent on the operating surface and achieve the purpose of efficient cleaning of the operating surface.

[0052] In some embodiments, the first liquid outlet 111 can be provided with multiple rows, and the multiple rows of first liquid outlets 111 are arranged in cross or non-cross on the first water distribution plate 121. When the first water distribution plate 121 is connected to the cleaning liquid supply pipeline, the cleaning liquid can flow out of different first liquid outlets 111.

[0053] In some embodiments, as shown in FIG. 2, the rolling brush 200 includes an outer cylinder 210 and an inner cylinder 220, the outer cylinder 210 is configured to clean the surface to be cleaned in cooperation with the cleaning liquid; the inner cylinder 220 is arranged inside the outer cylinder 210; wherein the heating device 400 is arranged in the inner cylinder 220 to heat the inner cylinder 220. Generally, the inner cylinder 220 is fixed, and the outer cylinder 210 rotates around the inner cylinder 220 to clean the surface to be cleaned. The inner cylinder 220 can be made of a material with good thermal conductivity, such as metal or alloy, or can be made of plastic or rubber material. The heating device 400 is an electric heating method, which is connected to an external electrode through an electrode terminal, and the electrode terminal is powered by the control device of the cleaning equipment to make the heating device 400 heat. The heating device 400 can include a resistance wire or a heating wire or a heating chip, etc. The external electrode can be arranged on the connecting arm 300, and the connecting arm 300 is connected to an external power supply and supplies power to the heating device 400 through the external electrode and the electrode terminal. The heating device 400 heats the inner cylinder 220 with good thermal conductivity, and then transmits heat to the outer cylinder 210, thereby heating the cleaning liquid sprayed on the outer surface of the outer cylinder.

[0054] In some embodiments, the outer cylinder 210 is in contact with the inner cylinder 220 and rotates around the inner cylinder 220, and the outer cylinder 210 and the inner cylinder 220 form a double-layer structure, wherein the outer cylinder 210 of the outer layer rotates, and the inner cylinder 220 of the inner layer is fixed. The inner cylinder 220 directly transmits heat to the outer cylinder after being heated, and heats the cleaning liquid on the outer surface of the outer cylinder 210. The outer cylinder is usually made of rubber or plastic material, and can also be made of metal or alloy. The outer surface of the outer cylinder can be provided with a brush to enhance the cleaning efficiency. The shape and structure of the brush are not limited in the present application. The brush can be a scraping strip, a brush, or any other brush that can clean the operating surface. The cleaning liquid is directly sprayed onto the outer surface of the outer cylinder 210, and through the rotation of the outer cylinder 210, the cleaning liquid is rubbed with the outer cylinder 210 to clean the operating surface. Since the cleaning liquid is directly sprayed onto the outer surface of the outer cylinder 210, the cleaning liquid flows along the brush towards the operating surface as the outer cylinder 210 rotates. The cleaning liquid can uniformly cover the outer surface of the outer cylinder 210, and rubs with the operating surface as the outer cylinder 210 rotates to achieve efficient cleaning.

[0055] As the cleaning liquid has been heated by the heating device 400, the cleaning molecules of the heated cleaning liquid are more active, and can preferentially soften the stains on the operating surface during contact with the stains, and as the roller brush continuously rotates, the stains can be more easily removed under the action of friction, thereby facilitating efficient cleaning of the operating surface. In some embodiments, the outer cylinder 210 and the inner cylinder 220 have a gap 230 therebetween, and the gap 230 contains a heat-conducting medium; the heat-conducting medium is configured to transfer heat from the inner cylinder 220 to the outer cylinder 210. In some embodiments, the heat-conducting medium is a gas or a liquid. To enhance the flexibility of the rotation of the outer cylinder 210 and the inner cylinder 220, the gap 230 can be provided between the outer cylinder 210 and the inner cylinder 220, and a heat-conducting medium is provided between the inner cylinder 220 and the outer cylinder 210. The heated inner cylinder 220 transfers heat to the outer cylinder 210 through the heat-conducting medium, thereby heating the cleaning liquid sprayed onto the surface of the outer cylinder. When the heat-conducting medium is a gas, it can be air or other liquids. When the heat-conducting medium is a liquid, a sealing member is provided to seal the heat-conducting medium provided between the inner cylinder 220 and the outer cylinder 210 to prevent leakage.

[0056] In some embodiments, as shown in FIG. 3, the roller brush includes an outer cylinder 210 configured to clean the surface to be cleaned in cooperation with the cleaning liquid; and the heating device 400 is arranged on the inner surface of the outer cylinder 210 to heat the cleaning liquid. In some embodiments, the heating device 400 includes a slip ring 410 arranged at the end of the inner surface of the outer cylinder 210, the slip ring 410 rotates with the rotation of the outer cylinder 210, thereby forming a conductive part of the heating device 400; and a heating element 420 electrically connected to the slip ring 410, the heating element 420 is configured to heat the outer cylinder 210. The slip ring 410 is a conductive circular ring close to the inner surface of the outer cylinder 210, and the slip ring 410 is in sliding connection with an external conductive terminal 500. Through the external conductive terminal 500, current can be conducted to the slip ring 410, and then the slip ring 410 is electrically connected to the heating element 420. The heating element 420 heats the outer cylinder 210, thereby heating the cleaning liquid sprayed onto the outer surface of the outer cylinder 210, and enhancing the cleaning effect. The external conductive terminal 500 can be connected to the external electrode on the connecting arm 300. The connecting arm 300 is connected to an external power supply and supplies power to the heating element 420 through the external electrode, the external conductive terminal 500, and the slip ring 410.

[0057] In some embodiments, as shown in FIG. 1, the cleaning brush head further includes a connecting arm 300 in rotational connection with the outer cylinder 210 and configured to support the rotation of the outer cylinder 210.

[0058] In some other embodiments, the connecting arm 300 has a driving end 310 drivingly connected with the outer cylinder 210. The connecting arm 300 is connected with the driving assembly in the housing 100 directly or indirectly, and the driving force of the driving assembly is transmitted to the driving end of the outer cylinder 210, so that the outer cylinder 210 can be driven to rotate.

[0059] Optionally, the connecting arm 300 has a clamping portion fixedly connected with the inner cylinder 220. The specific structure of the clamping portion is not limited as long as it can fixedly connect the inner cylinder 220 and the connecting arm 300. The clamping portion fixes the inner cylinder 220 relative to the connecting arm 300, so that the electrical connection structure can be safely transmitted to the roller brush through the connecting arm 300 to heat the roller brush.

[0060] In some other embodiments, the connecting arm 300 and the roller brush 200 can be an integral part, that is, at least one end of the roller brush is fixedly connected with the roller brush 200. In this embodiment, the connecting arm 300 can not be provided with a clamping portion. The outer cylinder 210 of the roller brush 200 can be drivingly connected with the connecting arm 300, and is configured to drive the roller brush 200 to rotate at high speed relative to the connecting arm 300 under the action of the driving end, so as to realize the cleaning of the operation surface.
