[0057] Example 1

[0058] This embodiment provides a liquid supply mechanism, such as Figure 1As shown, in one embodiment, the liquid supply mechanism 100 is used for a surface cleaning device, and includes a liquid storage container 110 and an air pump 120. The liquid storage container 110 includes a container cavity 112 and an output structure 114, the output structure 114 is connected to the container cavity 112, the container cavity 112 is used to store liquid, and the output structure 114 is used to output the fluid in the container cavity 112. The air pump 120 is used to communicate with the container cavity 112 and inject gas into the liquid to form microbubble water. It should be noted that, usually, the liquid stored in the container cavity 112 is clean water, pure water or clean water, and of course, it can also be other liquids used for cleaning. When the air pump 120 does not inject gas into the clean water, pure water or clean water, the output structure 114 can output clean water, pure water or clean water; when the air pump 120 injects gas into the clean water, pure water or clean water to prepare microbubble water, the liquid stored in the container cavity 112 becomes microbubble water, and the output structure 114 can output microbubble water. Moreover, microbubble water is a water-gas mixture, which is not a liquid but a fluid; the corresponding output structure 114 can output the fluid in the container cavity 112.

[0059] By setting the air pump 120, the air pump 120 can be connected to the container cavity 112, and the gas is directly injected into the liquid in the container cavity 112, so as to prepare microbubble water, and the microbubble water can be supplied to the cleaning part of the surface cleaning equipment through the output structure 114, and the microbubble water is attached to the surface of the cleaning part, and then it will explode to produce a cavitation effect, and the dirt attached to the surface of the cleaning part will explode, so that the dirt will be separated from the surface of the cleaning part, and the dirt accumulated on the cleaning part will be greatly reduced or removed, thereby improving its cleaning effect; at the same time, the cleaning part uses the microbubble water to clean the ground, and the microbubble water is attached to the ground and produces the same effect, thereby improving the cleaning ability of the whole machine, and deep cleaning of the ground can be achieved. Moreover, as the gas is pumped in, the pressure in the container cavity 112 becomes larger and larger, and the dissolution effect of some gases in the liquid becomes better. When the output structure 114 outputs the microbubble water, the output structure 114 can play the role of reducing pressure and throttling, so that the gas dissolved in the water is continuously precipitated, and a large number of microbubbles are generated, thereby improving the concentration of microbubbles in the microbubble water.

[0060] The liquid storage container 110 also includes an air intake structure 116, which is connected to the container cavity 112. The output end of the air pump 120 is connected to the air intake structure 116 through a pipeline, so that the gas output by the air pump 120 can be directly injected into the liquid in the container cavity 112 through the air intake structure 116 to prepare slightly bubbled water.

[0061] Furthermore, the air intake structure 116 is disposed on the side of the container cavity 112, and the air pump 120 is connected to the air intake structure 116 through a pipeline. Obviously, in other embodiments, the air intake structure 116 can be disposed at the bottom of the container cavity 112, which has a better effect of preparing microbubble water; the air pump 120 can also be disposed inside the container cavity 112 through a waterproof structure, which can also directly inject gas into the liquid, and is conducive to the realization of integration and modularization.

[0062] Furthermore, the output structure 114 is tubular and disposed at the bottom of the container cavity 112 to facilitate liquid output. The output structure 114 can be disposed inside the container cavity 112 or outside the container cavity 112 and directly or indirectly delivers microbubble water or liquid to the cleaning element through a pipeline.

[0063] In the present embodiment, the liquid supply mechanism 100 further includes a liquid pump 130, which is used to communicate with the output structure 114 and output liquid. By controlling the output of the microbubble water or liquid in the container cavity 112 by the liquid pump 130, accurate liquid supply can be achieved, the liquid supply efficiency is improved, and the different liquid supply requirements of different surfaces to be cleaned are met. Among them, the input end of the liquid pump 130 can be connected to the output structure 114 through a pipeline, and the output end of the liquid pump 130 can output liquid to the cleaning part through a pipeline. It is understandable that in other embodiments, the liquid supply mechanism 100 may not be provided with a liquid pump 130, and the output structure 114 can use gravity and the pressure in the container cavity 112 to drip the microbubble water or liquid onto the cleaning part.

[0064] In this embodiment, the liquid supply mechanism 100 further includes a liquid valve 140 and a heater 150. The liquid valve 140 includes a second liquid inlet 142 and two second liquid outlets 144, and any one of the two second liquid outlets 144 can be switched to be connected to the second liquid inlet 142. The second liquid inlet 142 is connected to the liquid pump 130, and one second liquid outlet 144 is used to output liquid to the cleaning part of the surface cleaning device. The heater 150 is connected to the other second liquid outlet 144, and the heater 150 is used to heat the liquid to obtain a heating product, that is, hot water or water vapor, and output the heating product to the cleaning part.

[0065] By switching on the liquid valve 140, the microbubble water is delivered to the cleaning part or the heater 150. When the surface cleaning device uses hot water or steam to clean the surface, the liquid valve 140 conducts the liquid pump 130 and the heater 150, and the microbubble water is delivered to the heater 150. The microbubbles in the microbubble water are ruptured by the heat in the heater 150, which causes the scale to separate from the inner surface of the heater 150, thereby achieving the effect of cleaning the scale, greatly reducing or removing the scale in the heater 150, and increasing the service life of the heater 150. When the surface cleaning device uses microbubble water to clean the surface, the liquid valve 140 conducts the liquid pump 130 and the cleaning part, and the microbubble water is delivered to the cleaning part.

[0066] In this embodiment, the liquid valve 140 is an electromagnetic reversing valve, which has reliable performance and is easy to switch and control. Among them, its second liquid inlet end 142 and two second liquid outlet ends 144 can be one end of the protruding tube body or one end of the channel on the valve body.

[0067] The surface cleaning device also includes a water separator 202, which is arranged corresponding to the cleaning part, and can output liquid or water vapor to the cleaning part. Among them, the water separator 202 has two input ends, one of which is connected to a second liquid outlet 144 of the liquid valve 140 through a pipeline, and the other input end is connected to the heater 150 through a pipeline, and the heater 150 is connected to another second liquid outlet 144 of the liquid valve 140 through a pipeline, and the second liquid inlet 142 of the liquid valve 140 is connected to the output end of the liquid pump 130 through a pipeline. It should be noted that the surface cleaning device can be but not limited to a handheld cleaning device, a self-moving cleaning device, an intelligent cleaning device or other cleaning devices. The cleaning part can be but not limited to a roller brush, a mop, a rag or a crawler cleaning cloth.

[0068] See also Figure 2 , Figure 2 The principle block diagram of another embodiment of the liquid supply mechanism provided in Example 1 of the present invention is shown. Compared with the liquid supply mechanism 100 in the above embodiment, the air pump 120 of the liquid supply mechanism 100 in this embodiment is connected to the container cavity 112 through the output structure 114. The output structure 114 is usually arranged at the bottom of the container cavity 112 or near the bottom to facilitate the output of the liquid. Therefore, the gas input into the container cavity 112 by the air pump 120 moves from bottom to top in the liquid, which can increase the content of microbubbles in the microbubble water and improve the preparation efficiency of the microbubble water.

[0069] In this embodiment, the liquid supply mechanism 100 further includes a communicating vessel 160, and the communicating vessel 160 is provided with a spaced liquid outlet channel 161 and an air inlet channel 162. The liquid outlet channel 161 includes a first liquid inlet end and a first liquid outlet end, the first liquid inlet end is connected to the output structure 114, and the first liquid outlet end is used to output liquid. The air inlet channel 162 includes an air inlet end and an air outlet end, the air inlet end is connected to the air pump 120, and the air outlet end is located in the first liquid inlet end 163 and is connected to the container cavity 112 through the output structure 114. Among them, the first liquid inlet end can be directly connected to the output structure 114 or connected to the output structure 114 through a pipeline, the first liquid outlet end is connected to the liquid pump 130 through a pipeline, and the air inlet end is connected to the output end of the air pump 120 through a pipeline.

[0070] Since the liquid outlet channel 161 and the air inlet channel 162 are arranged at intervals, the liquid output from the liquid outlet channel 161 and the gas input from the air inlet channel 162 will not interfere with each other, so that the liquid outlet channel 161 can smoothly output the liquid. Moreover, the air outlet end is located in the first liquid inlet end. When the first liquid inlet end is connected to the output structure 114, the air outlet end is naturally connected to the output structure 114 without being connected separately. It should be noted that, in other embodiments, the connecting vessel 160 can be a three-way structure with two input ends and one output end, wherein one input end is connected to the output structure 114, the other input end is connected to the air pump 120, and the output end is connected to the liquid pump 130.

[0071] As for other aspects of the liquid supply mechanism 100 of this embodiment, they are basically the same as other aspects of the liquid supply mechanism 100 of the above-mentioned embodiment. The specific contents can be referred to the description of the above-mentioned embodiment, and will not be repeated here.

[0072] Example 2

[0073] This embodiment provides a surface cleaning device, such as Figure 3 and Figure 4 As shown, in one embodiment, the surface cleaning device 200 includes a liquid supply mechanism 100, a body 210 and a cleaning device 220, wherein the cleaning device 220 is disposed on the body 210 and includes a cleaning member 222. At least a portion of the liquid supply mechanism 100 is disposed on the body 210 or the cleaning device 220. The specific structure of the liquid supply mechanism 100 refers to the above-mentioned embodiment 1. Since the surface cleaning device 200 of this embodiment adopts all the technical solutions of the above-mentioned embodiment 1, it also has all the beneficial effects brought by the technical solutions of the above-mentioned embodiment 1, which will not be described one by one here.

[0074] In this embodiment, the body 210 is a handheld structure, and the surface cleaning device 200 is a handheld cleaning device. Part of the liquid supply mechanism 100 is arranged on the body 210, and the other part is arranged on the cleaning device 220, and the cleaning device 220 is the cleaning head or floor brush of the handheld cleaning device. It should be noted that in other embodiments, the body 210 can be a shell, and the surface cleaning device 200 can be a cleaning robot, such as a floor washing robot, a mopping robot or a mopping robot, and the cleaning device 220 can include a driving mechanism and a cleaning member, and the driving mechanism is used to drive the cleaning member; and at least part of the liquid supply mechanism 100 is arranged in the shell or part of the liquid supply mechanism 100 is arranged in the shell, and the other part is arranged on the cleaning device 220.

[0075] In this embodiment, the body 210 includes a mounting frame 212, a connecting shell 214 and a connecting head 216. The connecting shell 214 is connected between one end of the mounting frame 212 and the connecting head 216. The connecting head 216 is rotatably connected to the cleaning device 220. A mounting seat 218 is provided on both the front and rear sides of one end of the mounting frame 212. The liquid storage container 110 of the liquid supply mechanism 100 is provided on the mounting seat 218 at the rear side of the mounting frame 212, and the connecting vessel 160 of the liquid supply mechanism 100 is provided on the mounting seat 218 at the rear side, and docks with the liquid storage container 110.

[0076] See also Figures 5 to 9 , Figure 5 1 shows a side view of the surface cleaning apparatus in this embodiment, Figure 6 Shows Figure 5 Partial cross-sectional view of the surface cleaning equipment, Figure 7 Shows Figure 6 A partial enlarged view of area A of the surface cleaning equipment. Figure 8 A partial cross-sectional view of a liquid storage container of a liquid supply mechanism of a surface cleaning device in this embodiment is shown. Fig. 9 The exploded view of the communicating vessel of the liquid supply mechanism of the surface cleaning device in this embodiment is shown. The liquid storage container 110 can be detachably arranged on the body 210, that is, it can be detachably arranged on the mounting seat 218 on the rear side, so as to facilitate the removal and replenishment of the liquid therein. The output structure 114 is a water outlet valve 170 arranged in the container cavity 112. The water outlet valve 170 has an output flow channel 171, and the output flow channel 171 is connected to the container cavity 112. The water outlet valve 170 includes a valve core 172, and the valve core 172 can be elastically retracted and arranged in the output flow channel 171 to cut off or conduct the output flow channel 171. Among them, the first liquid inlet end 163 of the communicating vessel 160 is connected to the output flow channel 171, and the air outlet end 166 abuts against the valve core 172, so that the valve core 172 elastically contracts and conducts the output flow channel 171, and the air outlet end 166 is provided with a lateral air outlet 167, and the lateral air outlet 167 is connected to the output flow channel 171.

[0077] When the liquid storage container 110 is assembled on the body 210, the liquid storage container 110 can be fixed on the rear mounting seat 218 through the buckle structure, wherein the first liquid inlet end 163 is connected to the output flow channel 171, and the gas outlet end 166 abuts against the valve core 172, so that the valve core 172 shrinks and conducts the output flow channel 171. Figure 7 As shown, the output channel 171 connects the container cavity 112 and the first liquid inlet end 163, and the lateral gas outlet 167 of the gas outlet end 166 can output gas laterally, and the gas can enter the container cavity 112 through the output channel 171. When the liquid storage container 110 on the body 210 is disassembled, the liquid storage container 110 is removed from the rear mounting seat 218 by operating the buckle structure. At this time, the gas outlet end 166 no longer abuts the valve core 172, and the valve core 172 elastically extends to cut off the output channel 171, as shown in FIG. Figure 8 As shown, the liquid is prevented from flowing out of the output flow channel 171, causing dripping or leakage of the liquid storage container 110. It should be noted that in other embodiments, the liquid storage container 110 can be arranged in a non-detachable manner, and the output structure 114 does not need to adopt a water outlet valve structure.

[0078] A water outlet hole 118 is provided on the cavity wall of the container cavity 112. The water outlet valve 170 further includes a valve body 173 and an elastic member 174. The valve body 173 is provided on the cavity wall of the container cavity 112 corresponding to the water outlet hole 118 to form an output flow channel 171. The elastic member 174 is provided between the valve core 172 and the valve body 173. The valve core 172 can cut off or conduct the water outlet hole 118. By using part of the cavity wall of the container cavity 112 to form the output flow channel 171, the structure of the water outlet valve 170 can be simplified, its parts can be reduced, and the cost can be reduced.

[0079] Furthermore, the valve body 173 is sleeve-shaped, one end of which is closed, and the other end is connected to the bottom wall of the container cavity 112. A plurality of circumferentially spaced communication openings (not shown) are provided on the side wall, and the communication openings communicate with the inside and outside of the valve body 173. The water outlet valve 170 also includes a filter 175, which is cylindrical and nested in the valve body 173. The liquid in the container cavity 112 can pass through the communication opening and the filter holes of the filter 175 in sequence and enter the output flow channel 171. The filter 175 can filter impurities in the liquid to prevent blockage of the flow channel, and the filter holes of the filter 175 can play a role in reducing pressure and throttling.

[0092] Example 3

[0093] This embodiment provides a liquid supply method, such as Fig.12 As shown, in one embodiment, the liquid supply method can be implemented based on the liquid supply mechanism 100 of the above embodiment 1 or the surface cleaning device 200 of the above embodiment 2, and the surface cleaning device 200 includes a deep cleaning mode, a self-cleaning mode and a conventional cleaning mode. The user can switch the above modes as needed, and the cleaning mode of the surface cleaning device 200 is not limited to the above-mentioned modes. The deep cleaning mode is to control the liquid supply mechanism 100 to prepare microbubble water and supply microbubble water to the cleaning member 222 to perform surface cleaning. The self-cleaning mode is to control the liquid supply mechanism 100 to prepare microbubble water and supply microbubble water to the heater 150, and use the microbubble water to self-clean the scale in the heater 150, and supply hot water / steam to the cleaning member 222. The conventional cleaning mode is that there is no need to prepare microbubble water, and the liquid supply mechanism 100 supplies liquid to the heater 150 or the cleaning member 222, which can be divided into a hot water / steam cleaning mode and a normal temperature water cleaning mode.

[0094] In this embodiment, the liquid supply method includes:

[0095] S100, controlling the air pump 120 to inject gas into the liquid in the liquid storage container 110 to prepare micro bubble water;

[0096] S200, controlling the liquid valve 140 to switch on; and

[0097] S300 , controlling the liquid pump 130 to output the microbubble water to the cleaning element 222 or the heater 150 through the liquid valve 140 .

[0098] When the surface cleaning device 200 enters the deep cleaning mode, the control liquid valve 140 switches the water divider 202 and the liquid storage container 110, and the liquid pump 130 pumps the microbubble water in the container cavity 112 of the liquid storage container 110 to the water divider 202, which is then applied to the cleaning element 222 by the water divider 202. The microbubble water is used to clean the dirt accumulated on the cleaning element 222, thereby improving the cleaning effect of the cleaning element 222. At the same time, the microbubble water is used to clean the floor, thereby improving the cleaning ability of the entire machine and achieving deep cleaning of the floor. When the surface cleaning device 200 enters the self-cleaning mode, the control liquid valve 140 switches on the heater 150 and the liquid storage container 110, and the liquid pump 130 pumps the microbubble water in the container cavity 112 to the heater 150, which is then heated into hot water or water vapor by the heater 150. The hot water or water vapor is applied to the cleaning element 222 through the water separator 202, wherein the microbubble water can promote the removal of scale deposited on the inner wall of the heater 150, thereby increasing the service life of the heater 150.

[0099] It should be noted that in other embodiments, the liquid valve 140 can be controlled to switch on first, and then the air pump 120 can be controlled to inject gas into the liquid in the liquid storage container 110; or the liquid valve 140 can be controlled to switch on and the air pump 120 can be controlled to inject gas into the liquid in the liquid storage container 110 at the same time.

[0100] Before step S100 or after step S300, the liquid supply method further includes:

[0101] S400, control the liquid valve 140 to switch on; and

[0102] S500 , controlling the liquid pump 130 to output the liquid to the cleaning member 222 or the heater 150 through the liquid valve 140 .

[0103] When the surface cleaning device 200 enters the regular cleaning mode, it can clean the floor with liquid or hot water / steam. The regular cleaning mode can be executed before or after the deep cleaning mode and / or the self-cleaning mode. Obviously, the user can flexibly select any of the above three modes according to actual needs, and combine the execution order of different cleaning modes.

[0104] Obviously, the embodiments described above are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, ordinary technicians in this field can make other different forms of changes or modifications without creative work, which should fall within the scope of protection of the present invention.
