In addition, the terms "first", "second", "third" and the like are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0036] It should be understood that the term "and / or" as used herein merely describes an associated relationship, that is, there can be three cases, such as A and / or B, which can represent the following three cases: A exists alone, A and B exist together, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the front and rear associated objects.

[0038] It should also be noted that the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the goods or devices including a series of elements not only include those elements, but also include other elements not explicitly listed, or include elements inherent to such goods or devices. Without more limitation, the element defined by the sentence "including a…" does not exclude the presence of another identical element in the goods or devices including the element.

[0039] In the related art, the cleaning device may have the problem of not cleaning the operation surface completely when cleaning the stubborn stains on the operation surface. To this end, the related art usually uses hot water to clean the operation surface by increasing the water temperature. However, since the heating device only increases the temperature of the first liquid, the third liquid may still have the phenomenon of not being cleaned completely by the cleaning device due to insufficient cleaning force.

[0040] Therefore, the present disclosure provides a cleaning device, which comprises: a mixing part having a first liquid inlet, a second liquid inlet and a third liquid outlet, a first liquid and a second liquid entering the mixing part through the first liquid inlet and the second liquid inlet respectively, and a third liquid formed by mixing, the third liquid flowing out through the third liquid outlet; a brush head comprising a cleaning element, the cleaning element and the third liquid acting on a to-be-cleaned operation surface together; a water outlet arranged downstream of the third liquid outlet and configured to spray the third liquid; and 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 the temperature of the third liquid flowing out from the liquid outlet after being heated is higher than or equal to 10% of the temperature of the second liquid added from the second liquid inlet.

[0041] The cleaning device provided by the present disclosure can mix the first liquid with the second liquid to form a third liquid, heat the first liquid or the third liquid by using a heating device, improve the activity of cleaning molecules in the second liquid, and further enable the second liquid in the third liquid to have better cleaning power, thereby solving the problem of insufficient cleaning power of the cleaning device on stubborn stains on the operation surface and improving the user experience.

[0042] The optional embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0043] The cleaning device 1000 provided by the present embodiment of the present disclosure comprises a mixing part 100, a brush head 300, a water outlet 200, and a heating device 400. As shown in FIG. 1 and FIG. 2, the mixing part 100 comprises a first liquid inlet 110, a second liquid inlet 120, and a third liquid outlet 130, and the water outlet 200. The first liquid inlet 110 and the second liquid inlet 120 are respectively connected with a first liquid supply source and a second liquid supply source. The first liquid supply source can be a first liquid tank or an external water source, and the second liquid supply source can be a second liquid tank. 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 part to form a third liquid, and the third liquid flows out of the third liquid outlet 130. In the present disclosure, the first liquid refers to general domestic water without active addition of the second liquid, including but not limited to tap water, pure water, mineral water, etc. The second liquid refers to a cleaning agent, i.e., a chemical substance or a mixed liquid for cleaning the surface of an object, which usually comprises solvent, surfactant, chelating agent, oxidizing agent, etc.

[0044] In some embodiments, as shown in FIG. 3, the cleaning device 1000 further comprises a water pump 140 connected with the second liquid inlet 120 and configured to pump the second liquid into the mixing part 100.

[0045] In some embodiments, the cleaning device 1000 is further provided with a water outlet 200 arranged on the brush head 300 and located downstream of the third liquid outlet 130, and configured to receive the third liquid flowing out of the third liquid outlet 130 and spray the third liquid towards the operation surface or the cleaning part 310.

[0046] In some embodiments, the brush head 300 can be arranged downstream of the mixing portion 100, which can be arranged on the body of the cleaning device, or the mixing portion 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 that cooperates with the third liquid to act on the surface to be cleaned. In response to the first liquid and the second liquid entering the mixing portion 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 portion 100 to form a third liquid. The third liquid mixed inside the mixing portion 100 can flow to the water outlet 200 through the third liquid outlet 130, and finally be sprayed by the water outlet 200 to the cleaning member 310 of the brush head 300.

[0047] It should be noted that the position of the water outlet 200 is not specifically limited in the present disclosure, and the water outlet 200 can be arranged on the brush head 300 or inside the cleaning member 310. Whether the water outlet 200 is arranged on the brush head 300 or inside the cleaning member 310, the mixed third liquid can be sprayed to the cleaning member 310 or the surface to be cleaned.

[0048] In some embodiments, in order to improve the activity of cleaning molecules in the second liquid, a heating device 400 is further arranged inside the cleaning device 1000, configured to heat the first liquid and / or the second liquid.

[0049] The heating device 400 can be arranged between the mixing portion 100 and the water outlet 200, i.e., 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, so as to improve the activity of cleaning molecules in the second liquid and further achieve efficient cleaning of the surface to be cleaned.

[0050] Specifically, the first liquid and the second liquid mixed in the mixing portion 100 form a third liquid, which flows out of the third liquid outlet 130. Further, since the heating device 400 is arranged 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 are more active, and the cleaning efficiency of stubborn stains on the surface to be cleaned is higher. The cleaning ability of the second liquid on the surface to be cleaned can be improved, and the purpose of efficient cleaning of the surface to be cleaned can be achieved.

[0051] Specifically, the heating device 400 can be a PTC heater, a stainless steel heating pipe, an electromagnetic heater, a thick film heater, etc. commonly used in the art. The heating device 400 can heat the liquid passing therethrough in a short time, and the specific implementation mode is not limited here.

[0052] In some embodiments, as shown in FIG. 4, 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 part 100 has been heated by the heating device 400. Inside the mixing part 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 activity of the cleaning molecules in the second liquid is stronger. During the cleaning operation, it is easier to remove stains and achieve efficient cleaning. The first liquid and the second liquid are mixed in the mixing part 100 to form a third liquid, which is discharged from the third liquid outlet 130 and sprayed 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 part 100. The activity of the cleaning molecules in the second liquid is more significantly improved by the hot water. When the mixed third liquid is sprayed 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 operation surface, which is beneficial to remove stubborn stains on the surface of the operation surface.

[0053] 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 from the second liquid inlet 120. Since the temperature of the third liquid containing the second liquid is increased, the cleaning active molecules in the third liquid are more active, which helps to improve the cleaning power on the operation surface.

[0054] The inventor has conducted a large number of studies on the relationship between the temperature increase of the second liquid and the cleaning effect on the surface such as the ground, and found that if the temperature of the liquid discharged by the heater can be controlled to increase by more than 10% compared to the temperature of the added second liquid, the cleaning power on hard surfaces such as ceramic tiles, wooden floors, and glass can be increased by 25%-40%. If the temperature increase is too low, it is difficult to stimulate the activity of the cleaning active molecules in the third liquid, and the desired cleaning power cannot be achieved. For example, when the temperature of the added second liquid is normal temperature of 20-25 degrees, if the temperature of the liquid discharged by the heater is controlled to be more than 23-30 degrees, the third liquid is used to clean various types of hard surfaces through cleaning equipment such as a floor cleaning machine. Originally, it takes 10 seconds to remove stains, but now it only takes 6 seconds or less to remove stains, greatly improving the cleaning effect on the surface such as the ground.

[0055] In some embodiments, the third liquid in the mixing part 100 is sprayed to the cleaning member 310 through the water outlet 200. The brush head 300 is arranged downstream of the mixing part 100 and is configured to receive the third liquid flowing out of the mixing part 100. The brush head 300 has a cleaning member 310 that cooperates with the third liquid to clean the operation surface. The shape and structure of the cleaning member 310 are not limited in the present disclosure. The cleaning member 310 can be a roller brush with a scraping strip or a brush, or any other structure that can clean the operation surface.

[0056] In some embodiments, as shown in FIG. 5, the mixing part 100 can be a first liquid tank of the cleaning equipment 1000. 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 to mix the first liquid and the second liquid in the first liquid tank to form a third liquid. Since the mixing part 100 is a 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 and is sprayed to the cleaning member 310 or the operation surface through the water outlet 200 to clean the operation surface.

[0057] The water outlet 200 can also be arranged on the side of the cleaning member 310 and extend towards the moving direction of the cleaning equipment. Specifically, the cleaning member 310 has an inner cylinder and an outer cylinder. In response to the cleaning equipment 1000 being in a working state, the outer cylinder rotates at a high speed around the inner cylinder to clean the ground. The water outlet 200 can be arranged on the side wall of the inner cylinder.

[0058] It should be noted that the present disclosure does not specifically limit the position and number of the water outlet 200, which can be provided on one side or both sides, and one or more water outlets 200 can be provided on one side of the cleaning member 310 to spray the third liquid to the cleaning member 310 or the operating surface.

[0059] Specifically, as the cleaning device 1000 moves, the water outlet 200 sprays the third liquid to the front of the moving direction of the cleaning device 1000, and when the cleaning device 1000 continues to move towards the moving direction, it will pass through the spray position sprayed by the water outlet 200 last time. Further, the cleaning member 310 is rotated at a high speed to rub against the operating surface, so that the third liquid and the cleaning member 310 jointly clean the operating surface.

[0060] In some embodiments, the cleaning device 1000 further comprises a control unit configured to control the working state of the water outlet 200. The water outlet 200 has a working state and a resting state. When the water outlet 200 is in the working state, the water outlet 200 sprays the third liquid to 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 cleaned, the user can control the water outlet 200 to switch between the working state and the resting state to spray the third liquid to the brush head 300 or the operating surface to assist the cleaning of the operating surface.

[0061] In some embodiments, the water outlet 200 only sprays the third liquid to the cleaning member 310, and through the rotation of the cleaning member 310, the third liquid rubs against the cleaning member 310 at a high speed to clean the operating surface. Since the third liquid is only sprayed to the surface of the cleaning member 310, the third liquid flows along the cleaning member 310 to the operating surface through the rotation of the cleaning member 310, and the third liquid rubs against the operating surface at a high speed with the cleaning member 310 to achieve efficient cleaning. Since the flow range of the third liquid is small, the sewage generated after cleaning the operating surface is more easily sucked into the sewage tank by the collecting device.

[0062] In some embodiments, the water outlet 200 can be provided between the cleaning member 310 and the third liquid outlet 130 and configured to spray the third liquid to the cleaning member 310.

[0063] In some embodiments, the water outlet comprises a first water outlet and a second water outlet; the first water outlet is configured to spray the third liquid to the cleaning member 310; the second water outlet is configured to spray the third liquid to the operation surface. Specifically, the water outlet 200 can spray the third liquid to the operation surface and the cleaning member 310 at the same time. In this embodiment, the third liquid is not only sprayed to the cleaning member 310, but also to the operation surface. The first water outlet and the second water outlet can be controlled by the control unit to spray water individually, simultaneously or staggered.

[0064] Since the third liquid has been heated by the heating device 400, the cleaning molecules in the third liquid are more active, and can preferentially soften the stains on the operation surface during contact with the ground stains. When the cleaning device 1000 moves for cleaning, the stains can be removed more easily, which is beneficial to achieve efficient cleaning of the operation surface. The user can manually or automatically control the water outlet 200 to spray water to the cleaning member 310 or the operation surface, or to both the cleaning member 310 and the operation surface, to assist in cleaning the stains on the surface of the operation surface.

[0065] In some embodiments, the cleaning device further comprises a sensor, which can be arranged at the bottom of the brush head and configured to determine whether there is stubborn stain on the operation surface and transmit a water spraying signal to the control unit. In response to the sensor detecting the first stubborn stain that is not completely removed during cleaning, the sensor transmits a water spraying signal to the control unit, and the control unit receives the water spraying signal and sprays the third liquid with a certain temperature to the cleaning member 310 or the operation surface, so that the third liquid cleans the stains on the surface of the operation surface.

[0066] In some embodiments, the brush head 300 further comprises water outlets arranged through the outer surface of the brush head 300 and configured to allow the third liquid to flow. The water outlets are arranged in a matrix on the surface of the brush head 300, which can make the third liquid flow out of the surface of the brush head 300. Further, the brush head 300 can assist in cleaning the operation surface.

[0067] 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, which will not be repeated here.

[0068] Finally, it should be noted that: the embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts of each embodiment can be referred to each other. For the system or device disclosed in the embodiments, since it corresponds to the method disclosed in the embodiments, the description is relatively simple, and the related parts can be referred to the method part.

[0069] The above examples are only used to illustrate the technical solutions of the present disclosure, rather than limit the same; although the present disclosure is described in detail with reference to the foregoing examples, those of ordinary skill in the art should understand that the technical solutions recorded in the foregoing examples can be modified, or some technical features thereof can be replaced by equivalents; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present disclosure.
