[0040] In related art, cleaning equipment may not fully clean stubborn stains on worktops. To address this, the technology typically uses hot water to increase the water temperature to remove stains. However, because the heating device only raises the temperature of the first liquid, the third liquid may still lack the cleaning power to prevent the cleaning equipment from fully cleaning.

[0041] In view of this, the present disclosure provides a cleaning device, comprising: a mixing part, the mixing part having a first liquid inlet, a second liquid inlet and a third liquid outlet, the first liquid and the second liquid enter the mixing part through the first liquid inlet and the second liquid inlet respectively, mix to form a third liquid, and the third liquid flows out through the third liquid outlet; a brush head, comprising a cleaning member, the cleaning member and the third liquid act together on the operating surface to be cleaned; a water outlet, arranged downstream of the third liquid outlet, configured to spray the third liquid; a heating device, arranged between the third liquid outlet and the water outlet, the heating device comprising a liquid inlet and a liquid outlet, and configured so that the temperature of the third liquid flowing out of the liquid outlet after heating is higher than or equal to 10% of the temperature of the second liquid added from the second liquid inlet.

[0042] The cleaning device provided by the present invention can mix the first liquid and the second liquid to form a third liquid, and use a heating device to heat the first liquid or the third liquid to increase the activity of the cleaning molecules in the second liquid, further enabling the second liquid in the third liquid to exert better cleaning power, thereby solving the problem of insufficient cleaning power of the cleaning device on stubborn stains on the operating surface and improving the user experience.

[0043] Optional embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0044] The embodiment of the present disclosure provides a cleaning device 1000, which includes: a mixing unit 100, a brush head 300, a water outlet 200, and a heating device 400. Figure 1 、 Figure 2 As shown, the mixing section 100 includes: a first liquid inlet 110, a second liquid inlet 120, a third liquid outlet 130 and a water outlet 200, wherein the first liquid inlet 110 and the second liquid inlet 120 are connected to the first liquid supply source and the second liquid supply source respectively. The first liquid supply source may be a first liquid tank or an external water source, and the second liquid supply source may be a second liquid tank, wherein the temperature of the second liquid is not higher than the room temperature. The first liquid and the second liquid are mixed in the mixing section to form a third liquid, and the third liquid flows out from the third liquid outlet 130. In the present disclosure, the first liquid refers to general domestic water without actively adding a second liquid, including but not limited to tap water, purified water, mineral water, etc., and the second liquid refers to a detergent, that is, a chemical substance or mixed liquid used to clean the surface of an object, usually including solvents, surfactants, chelating agents, oxidants and other ingredients.

[0045] In some embodiments, as Figure 3 As shown, the cleaning device 1000 further includes a water pump 140 , which is connected to the second liquid inlet 120 and is configured to pump the second liquid into the mixing part 100 .

[0046] In some embodiments, the cleaning device 1000 is also provided with a water outlet 200, which is provided on the brush head 300 and located downstream of the third liquid outlet 130, and is configured to receive the third liquid flowing out of the third liquid outlet 130 and spray the third liquid toward the operating surface or the cleaning member 310.

[0047] In some embodiments, the brush head 300 can be arranged downstream of the mixing section 100. The mixing section 100 can be arranged on the cleaning device body, or the mixing section 100 can also be arranged on the brush head 300, which is not specifically limited here; the brush head 300 has a cleaning member 310, and the cleaning member 310 and the third liquid act together on the operating surface to be cleaned. In response to the first liquid and the second liquid entering the mixing section 100 through the first liquid inlet 110 and the second liquid inlet 120 respectively, the first liquid and the second liquid are mixed in the mixing section 100 to form a third liquid. The third liquid mixed inside the mixing section 100 can flow to the water outlet 200 through the third liquid outlet 130, and finally be sprayed from the water outlet 200 to the cleaning member 310 of the brush head 300.

[0048] It should be separately noted that the present disclosure does not specifically limit the position of the water outlet 200. The water outlet 200 can be set on the brush head 300 or inside the cleaning part 310. Regardless of whether the water outlet 200 is set on the brush head 300 or inside the cleaning part 310, the mixed third liquid can be sprayed onto the cleaning part 310 or the operating surface.

[0049] In some embodiments, in order to increase the activity of cleaning molecules in the second liquid, a heating device 400 is further provided inside the cleaning apparatus 1000 , configured to heat the first liquid and / or the second liquid.

[0050] The heating device 400 can be arranged between the mixing part 100 and the water outlet 200, that is, the heating device 400 is located between the third liquid outlet 130 and the water outlet 200, and is configured to heat the third liquid flowing out of the third liquid outlet 130 to increase the cleaning molecular activity of the second liquid, thereby further achieving efficient cleaning of the operating surface.

[0051] Specifically, the first liquid and the second liquid mixed in the mixing part 100 form a third liquid, which flows out from the third liquid outlet 130. Furthermore, since a heating device 400 is provided between the third liquid outlet 130 and the water outlet 200, when the third liquid flows through the heating device 400, the third liquid is heated. Due to the thermal effect, the cleaning active molecules in the third liquid will be more active, and the cleaning efficiency of the stubborn stains on the surface of the operating surface will be higher, which can improve the cleaning power of the second liquid on the operating surface, thereby achieving the purpose of efficiently cleaning the operating surface.

[0052] Specifically, the heating device 400 can be a PTC heater, a stainless steel heating tube, an electromagnetic heater, a thick film heater, etc. commonly used in the field. The heating device 400 can heat the passing liquid in a short time, and the specific implementation method is not specifically limited here.

[0053] In other embodiments, Figure 4 As shown, the heating device 400 is arranged upstream of the first liquid inlet 110 and is configured to heat the first liquid. At this time, the first liquid flowing into the mixing section 100 has been heated by the heating device 400. Inside the mixing section 100, the heated first liquid is mixed with the second liquid. At this time, due to the thermal effect, the fusion rate of the second liquid and the heated first liquid is faster, and the cleaning molecules in the second liquid are more active. When cleaning the operating surface, it is easier to remove stains and achieve the purpose of efficient cleaning. The first liquid and the second liquid are mixed in the mixing section 100 to form a third liquid. After the third liquid flows out from the third liquid outlet 130, it is sprayed out from the water outlet 200. Since the heating device 400 is arranged upstream of the first liquid inlet 110, the second liquid can be directly mixed with hot water in the mixing section 100, and the hot water can more significantly enhance the activity of the cleaning molecules in the second liquid. When the mixed third liquid is sprayed out from the water outlet 200, the third liquid, which is higher than room temperature, has a certain softening effect on the stains on the surface of the work surface, which is beneficial to removing stubborn stains on the surface of the work surface.

[0054] In some embodiments, the heating device 400 includes a liquid inlet and a liquid outlet. The third liquid or the first liquid flows into the heating device 400 through the liquid inlet and flows out of the heating device 400 through the liquid outlet. Preferably, the temperature of the third liquid or the first liquid flowing out of the third liquid outlet 130 is higher than or equal to 10% of the temperature of the second liquid added through the second liquid inlet 120. As the temperature of the third liquid containing the second liquid increases, the cleaning active molecules in the third liquid become more active, which helps to improve the cleaning power of the worktop.

[0055] The inventors conducted extensive research on the relationship between the temperature increase of the second liquid and the cleaning effect on surfaces such as floors. They found that if the temperature of the liquid outlet from the heater can be raised by more than 10% compared to the temperature of the added second liquid, the cleaning effect on hard surfaces such as tiles, wooden floors, and glass can be improved by 25%-40%. If the temperature increase is too low, it will be difficult to stimulate the activity of the cleaning active molecules in the third liquid, and the ideal cleaning effect will not be achieved. For example, when the temperature of the added second liquid is at room temperature of 20-25 degrees Celsius, if the temperature of the liquid outlet from the heater is controlled to above 23-30 degrees Celsius, and the third liquid is applied to various types of hard surfaces through cleaning equipment such as a floor scrubber, stains that originally took 10 seconds to remove can now be removed in 6 seconds or less, greatly improving the cleaning effect on surfaces such as floors.

[0056] In some embodiments, the third liquid in the mixing section 100 is sprayed to the cleaning member 310 via the water outlet 200. The brush head 300 is disposed downstream of the mixing section 100 and is configured to receive the third liquid flowing out of the mixing section 100. The brush head 300 includes a cleaning member 310 that works together with the third liquid to clean the operating surface. This application does not specifically limit the shape and structure of the cleaning member 310. The cleaning member 310 may be a roller brush with a scraping bar or a bristle brush, or any other structure capable of cleaning the operating surface.

[0057] In some embodiments, as Figure 5 As shown, the mixing part 100 can be the first liquid tank of the cleaning device 1000, and the first liquid and the second liquid are mixed in the first liquid tank. Specifically, the first liquid tank has a second liquid inlet 120. The second liquid is added to the mixing part 100, so that the first liquid and the second liquid are mixed in the first liquid tank to form a third liquid. Since the mixing part 100 is the first liquid tank, the liquid flowing out of the first liquid tank after mixing with the second liquid is the third liquid. The third liquid flows out of the first liquid tank through the third liquid outlet 130, flows to the water outlet 200, and is sprayed onto the cleaning member 310 or the operating surface to clean the operating surface.

[0058] The water outlet 200 can also be provided on the side of the cleaning member 310 and extend in the direction of movement of the cleaning device. Specifically, the cleaning member 310 comprises an inner cylinder and an outer cylinder. In response to the cleaning device 1000 being in operation, the outer cylinder rotates around the inner cylinder at high speed to clean the floor. The water outlet 200 can be provided on the side wall of the inner cylinder.

[0059] It should be noted that the present disclosure does not specifically limit the location and number of the water outlets 200. The water outlets 200 can be provided on one side or on both sides. One side of the cleaning member 310 can be provided with a single water outlet 200 or with two or more water outlets 200 to spray the third liquid onto the cleaning member 310 or the operating surface.

[0060] Specifically, as the cleaning device 1000 moves, the water outlet 200 sprays the third liquid forward in the direction of movement of the cleaning device 1000. As the cleaning device 1000 continues to move in the direction of movement, it passes through the last spraying position of the water outlet 200. Furthermore, the cleaning member 310 rotates at high speed, causing the cleaning member 310 to rub against the operating surface, so that the third liquid and the cleaning member 310 work together to clean the operating surface.

[0061] In some embodiments, the cleaning device 1000 further includes a control unit configured to control the operating state of the water outlet 200. The water outlet 200 has an operating state and a resting state. When the water outlet 200 is in the operating state, the water outlet 200 sprays the third liquid toward the cleaning member 310 or the operating surface; when the water outlet 200 is in the resting state, the water outlet 200 is at rest and does not spray the third liquid. When the operating surface of the cleaning device 1000 is being cleaned, the user can control the water outlet 200 to switch between the operating state and the resting state to spray the third liquid toward the brush head 300 or the operating surface to assist in cleaning the operating surface.

[0062] In some embodiments, the water outlet 200 sprays the third liquid only onto the cleaning member 310. As the cleaning member 310 rotates, the third liquid rubs against the cleaning member 310 at high speed, cleaning the worktop. Because the third liquid is sprayed only onto the surface of the cleaning member 310, it rotates and flows along the cleaning member 310 toward the worktop. As the cleaning member 310 rotates at high speed, the third liquid rubs against the worktop, achieving efficient cleaning. Because the third liquid has a smaller flow range, wastewater generated after cleaning the worktop is more easily drawn into the wastewater collection device.

[0063] In some embodiments, the water outlet 200 may be disposed between the cleaning member 310 and the third liquid outlet 130 , and configured to spray the third liquid toward the cleaning member 310 .

[0064] In some embodiments, the water outlet includes a first water outlet and a second water outlet; the first water outlet is configured to spray the third liquid toward the cleaning member 310; the second water outlet is configured to spray the third liquid toward the work surface. Specifically, the water outlet 200 can spray the third liquid toward both the work surface and the cleaning member 310 simultaneously. In this embodiment, the third liquid is sprayed not only toward the cleaning member 310 but also toward the work surface. The control unit can control the first and second water outlets to discharge water independently, simultaneously, or in an alternating pattern.

[0065] Because the third liquid has been heated by the heating device 400, the cleaning molecules in the third liquid are highly active and can preferentially soften the stains on the worktop during contact with the floor. This allows for easier removal of the stains during cleaning by the cleaning device 1000, facilitating efficient cleaning of the worktop. The user can manually or automatically control the water outlet 200 to spray water onto the cleaning element 310 or the worktop, or both, to assist in cleaning stains on the worktop.

[0066] In some embodiments, the cleaning device further comprises a sensor, which may be disposed at the bottom of the brush head and configured to determine whether stubborn stains are present on the operating surface and transmit a water spray signal to the control unit. In response to the presence of stubborn stains within the sensor's detection range that were not completely removed by the initial cleaning, the sensor transmits a water spray signal to the control unit. The control unit receives the water spray signal and sprays a third liquid having a predetermined temperature onto the cleaning member 310 or the operating surface, so that the third liquid cleans the stains on the operating surface.

[0067] In some embodiments, the brush head 300 further includes water outlet holes disposed through the outer surface of the brush head 300 and configured to allow the third liquid to flow. The water outlet holes are arranged in a matrix on the surface of the brush head 300, allowing the third liquid to flow out of the surface of the brush head 300. Furthermore, this assists the brush head 300 in cleaning the operating surface.

[0068] The specific structure, working principle, and beneficial effects of the cleaning device provided by the embodiments of the present disclosure can refer to the cleaning device described in any of the above embodiments and will not be elaborated here.

[0069] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. References to the common and similar parts between the various embodiments will be sufficient. For the systems or devices disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, their descriptions are relatively simple; for relevant details, refer to the descriptions of the methods.

[0070] The above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
