Description

Technical Field

[0001] The present invention relates to the technical field of floor cleaning equipment, and particularly provides a base for a floor cleaning equipment and a floor cleaning equipment assembly. Background Art

[0002] Currently, floor sweepers, mopping machines, vacuum mopping machines, etc. are used to clean the floor clean and efficiently. However, after the use of floor washing machines, mopping machines or vacuum mopping machines, most products need to disassemble parts for cleaning. For example, the cleaning roller brush needs to be cleaned. Common cleaning methods for the cleaning roller brush include hand washing and self-cleaning.

[0003] The hand washing method has low cleaning efficiency and high labor intensity, resulting in a poor user experience. Most self-cleaning methods involve rotating the roller brush in water for washing, but stains are not easily washed clean. Especially stains such as oil stains or dyes are difficult to wash off, resulting in poor self-cleaning effect. It may be necessary to remove the roller brush and clean it by hand washing again.

[0004] Correspondingly, the art needs a new technical solution to solve the above problems. Summary of the Invention

[0005] The present invention aims to solve the above technical problems, that is, to solve the problem that oil stains or dyes on the existing roller brush are not easily washed off, resulting in poor self-cleaning effect.

[0006] The present invention provides a base for a floor cleaning equipment, including a main body, a liquid storage tank and a pneumatic device;

[0007] A placement groove is provided on the upper surface of the main body, and a cleaning groove is provided in the placement groove. The cleaning groove allows the roller brush of the floor cleaning equipment to be placed therein;

[0008] The liquid storage tank is connected to the main body. An outlet hole is provided on the liquid storage tank. The air outlet end of the pneumatic device is close to the outlet hole and faces the cleaning groove. The pneumatic device is configured to enable the cleaning liquid in the liquid storage tank to be sprayed out of the outlet hole when the air outlet end of the pneumatic device discharges air, and to be sprayed onto the roller brush under the action of the gas.

[0009] In the case of adopting the above technical solution, the air outlet end of the pneumatic device is close to the outlet hole and faces the cleaning groove. When the air outlet end of the pneumatic device discharges air, the air pressure at the outlet hole is relatively low. The cleaning liquid in the liquid storage tank can be sprayed out of the outlet hole under the action of the air pressure. The sprayed cleaning liquid is mixed with the gas and sprayed onto the roller brush in the form of atomization under the action of the gas. Using the air pressure difference to spray the cleaning liquid out of the liquid storage tank makes it more convenient to add the cleaning liquid to the roller brush and has a better cleaning effect on oil stains or dyes on the roller brush.

[0010] In the specific implementation of the base of the above-mentioned floor cleaning device, it further includes a liquid outlet head, the liquid outlet head is installed at the liquid outlet hole, and a liquid outlet pipe communicating with the inside of the liquid storage bin is formed in the liquid outlet head, and at least part of the cross-section of the liquid outlet pipe gradually decreases along the liquid outlet direction.

[0011] In the case of adopting the above technical solution, the liquid outlet pipe in the liquid outlet head can communicate with the internal space of the liquid storage bin, and the cleaning liquid can be transported to a position suitable for spraying on the roller brush through the liquid outlet pipe, so that the cleaning liquid can be reasonably sprayed on the roller brush. At least part of the cross-section of the liquid outlet pipe gradually decreases along the liquid outlet direction, so that the cross-section of the liquid outlet end of the liquid outlet pipe is smaller, which is convenient for the cleaning liquid to spray out.

[0012] In the specific implementation of the base of the above-mentioned floor cleaning device, a conduit is connected to the lower end of the liquid outlet pipe, and the lower end of the conduit is located at the bottom of the liquid storage bin.

[0013] In the case of adopting the above technical solution, the lower end of the conduit is located at the bottom of the liquid storage bin, so that when there is a pressure difference between the upper end of the liquid outlet pipe and the inside of the liquid storage bin, the cleaning liquid at the bottom of the liquid storage bin can be sucked, avoiding the accumulation of the cleaning liquid at the bottom of the liquid storage bin.

[0014] In the specific implementation of the base of the above-mentioned floor cleaning device, the liquid outlet end of the liquid outlet pipe is located at the upper end of the liquid outlet head, and a fan-shaped groove is provided on one side of the upper end of the liquid outlet head facing the placement groove, and the fan-shaped groove extends outward from the liquid outlet end.

[0015] In the case of adopting the above technical solution, when the cleaning liquid reaches the upper end of the liquid outlet head, the cleaning liquid is sprayed along the gas flow direction, and the fan-shaped groove can increase the spraying area to achieve large-range spraying on the roller brush.

[0016] In the specific implementation of the base of the above-mentioned floor cleaning device, a convex edge is provided on the outside of the liquid outlet hole, and a connecting cover is provided on the outside of the liquid outlet head, and the connecting cover is buckled on the convex edge.

[0017] In the case of adopting the above technical solution, a cavity is formed between the outside of the liquid outlet head and the inside of the connecting cover through the connecting cover, and this cavity is communicated with the internal cavity of the liquid storage bin, avoiding air leakage between the liquid outlet head and the liquid outlet hole, resulting in the inability to pump out the cleaning liquid. At the same time, the liquid outlet head is fixed more stably.

[0018] In the specific implementation of the base of the above-mentioned floor cleaning device, it further includes a support frame, the support frame is connected to the liquid storage bin, and the air outlet end of the pneumatic device is connected to the support frame.

[0019] In the specific implementation of the base of the above-mentioned floor cleaning device, an air outlet is provided on the support frame. The air outlet faces the liquid outlet head and is located above the liquid outlet head. The air outlet end of the pneumatic device is communicated with the air outlet.

[0020] In the case of adopting the above technical solution, the gas above the liquid outlet head is accelerated through the air outlet. The air pressure above the liquid outlet head is relatively low, and the cleaning liquid is pumped out from the liquid storage tank. And after the gas and the cleaning liquid are mixed, they are sprayed onto the roller brush in an atomized form, so that the roller brush uniformly contacts the cleaning liquid.

[0021] In the specific implementation of the base of the above-mentioned floor cleaning device, an installation cavity communicated with the air outlet is provided on the support frame; and / or

[0022] The air outlet is a horizontally arranged long strip.

[0023] In the case of adopting the above technical solution, the installation cavity facilitates the connection and fixation of the air outlet pipe. The horizontally arranged long-strip air outlet can disperse the gas, so that the gas carries the cleaning liquid and contacts different positions of the roller brush.

[0024] In the specific implementation of the base of the above-mentioned floor cleaning device, the pneumatic device includes an air pump; and / or

[0025] The number of the cleaning tanks is two, and the number of the liquid storage tanks is two. The two liquid storage tanks supply liquid to the two cleaning tanks respectively; and / or

[0026] A liquid filling port is provided on the liquid storage tank.

[0027] The present invention also provides a floor cleaning device assembly, which includes a floor cleaning device and the above-mentioned base. The lower part of the floor cleaning device can be placed in the placement groove.

[0028] In the case of adopting the above technical solution, the air outlet end of the pneumatic device is close to the liquid outlet hole and faces the cleaning tank. When the air outlet end of the pneumatic device discharges air, the air pressure at the liquid outlet hole is relatively low, and the cleaning liquid in the liquid storage tank can be sprayed out from the liquid outlet hole under the action of the air pressure. The sprayed cleaning liquid is mixed with the gas under the action of the gas and is sprayed onto the roller brush in an atomized form. The cleaning liquid is sprayed out from the liquid storage tank by using the air pressure difference, which makes it more convenient to add the cleaning liquid to the roller brush and has a better cleaning effect on the oil stains or dyes on the roller brush.

Detailed implementation manners

[0038] The preferred implementation manners of the present application will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present application and are not used to limit the protection scope of the present application. Those skilled in the art can make adjustments according to needs to adapt to specific application scenarios. For example, although the air outlet holes in the specification are described in combination with horizontally arranged long strips, obviously, the air outlet holes of the present application can adopt other shapes, such as circular, square or polygonal, etc.

[0039] It should be noted that in the description of this application, unless otherwise clearly specified and defined, terms such as "arrangement" and "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or other connections; it can be directly connected or indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances. It should be understood that the orientation or positional relationship indicated by terms such as "upper" and "inner" is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0040] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings, in which: Figure 1 is an overall external structure diagram of the base for a floor cleaning device; Figure 2 is a structure diagram of the liquid supply part in the base for a floor cleaning device; Figure 3 is a front structure diagram of the liquid storage tank in the base for a floor cleaning device; Figure 4 is a rear structure diagram of the liquid storage tank in the base for a floor cleaning device; Figure 5 is a cross-sectional view of the liquid storage tank in the base for a floor cleaning device; Figure 6 is an enlarged view of the top of the liquid outlet head in the base for a floor cleaning device; Figure 7 is a cross-sectional view of the liquid outlet head in the base for a floor cleaning device.

[0041] As Figures 1-7 shown, to solve the problem that oil stains, dyes, etc. on the existing roller brush are not easy to wash off, resulting in poor self-cleaning effect, the present invention provides a base for a floor cleaning device, including a main body 1, a liquid storage tank 2 and a pneumatic device 5; a placement groove is provided on the upper surface of the main body 1, and a cleaning groove 11 is provided in the placement groove, and the cleaning groove 11 allows the roller brush of the floor cleaning device to be placed therein; the liquid storage tank 2 is connected to the main body 1, a liquid outlet hole is provided on the liquid storage tank 2, the air outlet end of the pneumatic device 5 is close to the liquid outlet hole and faces the cleaning groove 11, and the pneumatic device 5 is arranged so that when the air outlet end of the pneumatic device 5 discharges air, the cleaning liquid in the liquid storage tank 2 can be sprayed out from the liquid outlet hole and sprayed onto the roller brush under the action of the gas.

[0042] Thus, the air outlet end of the pneumatic device 5 is close to the liquid outlet hole and faces the cleaning tank 11. When the air outlet end of the pneumatic device 5 discharges air, the air pressure at the liquid outlet hole is relatively low, and the cleaning liquid in the liquid storage bin 2 can be sprayed out from the liquid outlet hole under the action of the air pressure. The sprayed cleaning liquid is mixed with the gas under the action of the gas and is sprayed onto the roller brush in the form of atomization. Using the air pressure difference method to spray the cleaning liquid out of the liquid storage bin 2 makes it more convenient to add the cleaning liquid to the roller brush and has a better cleaning effect on oil stains or dyes on the roller brush.

[0043] See Appendix Figure 1 and 2 , a preferred embodiment, the base of the floor cleaning device includes a main body 1, a liquid storage bin 2, a liquid outlet head 3, a support frame 4, and a pneumatic device 5.

[0044] A placement groove (not shown in the figure) is provided on the upper surface of the main body 1, and two cleaning tanks 11 are provided in the placement groove. The cleaning tanks 11 allow the roller brush of the floor cleaning device to be placed therein. A liquid spraying groove 12 is also formed on the main body 1, and the liquid spraying groove 12 is formed in the side wall of the cleaning tank 11 on the side away from the middle of the main body 1.

[0045] It should be noted that the number of cleaning tanks 11 can be determined according to the structure of the floor cleaning device to be placed. If the floor cleaning device to be placed has two roller brushes, two cleaning tanks 11 are provided. If the floor cleaning device to be placed has one roller brush, one cleaning tank 11 is provided. The number of liquid spraying grooves 12 is the same as the number of cleaning tanks 11. The liquid spraying groove 12 is for facilitating the spraying of the cleaning liquid onto the roller brush. Of course, the number of liquid spraying grooves 12 can also not be the same as the number of roller brushes. For example, only a single roller brush is sprayed with the cleaning liquid, and the other roller brush can be cleaned by conventional cleaning means in the art.

[0046] As Figure 2 shown, the number of liquid storage bins 2 is two, and the two liquid storage bins 2 supply liquid to the roller brushes above the two cleaning tanks 11 respectively. The two liquid storage bins 2 are both arranged on the lower side of the main body 1. A liquid filling port and an air inlet 21 are provided on the liquid storage bin 2. The liquid storage bin 2 is used to store the cleaning liquid. The liquid filling port is located on the upper side of the liquid storage bin 2, and the liquid filling port is connected to a liquid filling pipeline. Liquid is added to the liquid storage bin 2 through the liquid filling pipeline, and a pipeline valve is provided on the liquid filling pipeline to control the on-off of the liquid filling pipeline. The air inlet 21 is opened on the upper side of the liquid storage bin 2. When the cleaning liquid in the liquid storage bin 2 decreases, the air inlet 21 can intake air to balance the air pressure in the liquid storage bin 2. Two liquid outlet holes are provided on the upper side of the liquid storage bin 2, and the cleaning liquid can be discharged from the liquid storage bin 2 through the liquid outlet holes, and a convex edge 22 is provided outside the liquid outlet holes.

[0047] It should be noted that the setting method of the liquid storage bin 2 is not unique, and those skilled in the art can select the structure of the liquid storage bin 2 according to specific application scenarios. For example, the number of liquid storage bins 2 can be one, and the liquid is only supplied to the roller brush above one cleaning tank 11. Another example is that the air inlet 21 can be not provided, and the function of the air inlet 21 is realized through the liquid filling port. Another example is that the liquid filling pipeline can be not provided, and the cleaning liquid is directly added into the liquid storage bin 2 through the liquid filling port, and a detachable sealing cover is arranged at the position of the liquid filling port. Or the liquid storage bin 2 is directly set as two parts of a sealed connection bin body and a cover body, and the cleaning liquid is added by separating the bin body from the cover body.

[0048] As Figures 3-7 shown, a connection cover 33 is arranged on the outside of the liquid outlet head 3. The connection cover 33 is buckled on the convex edge 22 and is hermetically connected to the convex edge 22. A cavity is formed between the outside of the liquid outlet head 3 and the inside of the connection cover 33 through the connection cover 33, and this cavity is communicated with the internal cavity of the liquid storage bin 2, avoiding air leakage between the liquid outlet head 3 and the liquid outlet hole and causing the cleaning liquid not to be pumped out. At the same time, the liquid outlet head 3 is fixed more stably.

[0049] One end of the liquid outlet head 3 ( Figure 7 the lower end shown) is located inside the convex edge 22, and the other end of the liquid outlet head 3 ( Figure 7 the upper end shown) is located above the liquid storage bin 2. A liquid outlet pipeline 32 communicating with the inside of the liquid storage bin 2 is formed in the liquid outlet head 3, and at least part of the cross-section of the liquid outlet pipeline 32 gradually decreases along the liquid outlet direction. Specifically, the liquid outlet pipeline 32 is divided into three parts. The lowermost part of the liquid outlet pipeline 32 is a cylindrical cavity, the middle part of the liquid outlet pipeline 32 is a frustum-shaped cavity with a gradually shrinking cross-section, and the upper part of the liquid outlet pipeline 32 is a rectangular column cavity. The lower end of the liquid outlet pipeline 32 is communicated with a conduit, and the lower end of the conduit is located at the bottom of the liquid storage bin 2. In this way, the liquid outlet pipeline 32 in the liquid outlet head 3 can be communicated with the internal space of the liquid storage bin 2, and the cleaning liquid can be conveyed to a position suitable for spraying on the roller brush through the liquid outlet pipeline 32, so that the cleaning liquid can be reasonably sprayed on the roller brush. At least part of the cross-section of the liquid outlet pipeline 32 gradually decreases along the liquid outlet direction, so that the cross-section of the liquid outlet end of the liquid outlet pipeline 32 is smaller, which is convenient for the cleaning liquid to be ejected. The lower end of the conduit is located at the bottom of the liquid storage bin 2, so that when there is an air pressure difference between the upper end of the liquid outlet pipeline 32 and the inside of the liquid storage bin 2, the cleaning liquid at the bottom of the liquid storage bin 2 can be sucked, avoiding the accumulation of the cleaning liquid at the bottom of the liquid storage bin 2.

[0050] The liquid outlet end of the liquid outlet pipeline 32 is located at the upper end of the liquid outlet head 3. A fan-shaped groove 31 is arranged on one side of the upper end of the liquid outlet head 3 facing the placement groove, and the fan-shaped groove 31 extends outward from the liquid outlet end. In this way, when the cleaning liquid reaches the upper end of the liquid outlet head 3, the cleaning liquid is sprayed along the gas flow direction, and the fan-shaped groove 31 can increase the spraying area and realize large-range spraying on the roller brush.

[0051] It should be noted that, for the convenience of explaining the specific structure of the liquid outlet pipe 32, the liquid outlet pipe 32 is divided into three parts for description. It should be emphasized that the liquid outlet pipe 32 is only a cavity formed inside the liquid outlet head 3 and communicating with the inside of the liquid storage bin 2, and is not a physical feature. The description of the three parts of the liquid outlet pipe 32 here is a description of the shape of the cavity formed by enclosing this part, in order to further define the internal structure of the liquid outlet head 3. Of course, the setting of the liquid outlet pipe 32 is not unique. For example, the shape of the liquid outlet pipe 32 can be such that the overall cross-section gradually decreases from bottom to top. For another example, the lower side of the liquid outlet pipe 32 is a cylindrical cavity, and the cross-section of the remaining part gradually decreases from bottom to top. For another example, the cross-section of the lower side of the liquid outlet pipe 32 gradually decreases from bottom to top; the remaining part is a cylindrical cavity. For another example, the upper side part of the liquid outlet pipe 32 can be a cylindrical cavity, a square columnar cavity or a polygonal columnar cavity, etc. For another example, the lower side part of the liquid outlet pipe 32 can be a square columnar cavity or a polygonal columnar cavity, etc. For another example, the liquid outlet pipe 32 can also be a columnar or rectangular cavity with an unchanged internal cross-section.

[0052] It also should be noted that the setting of the liquid outlet head 3 is not necessary. Those skilled in the art can choose whether to set the liquid outlet head 3 and its specific structure based on the specific application scenario. Of course, the liquid outlet head 3 can also not be set. For example, the liquid outlet head 3 can not be set, an outlet hole is opened on the lower side of the liquid storage bin 2, the air outlet end of the pneumatic device 5 is located at the position of this outlet hole, and the size of the air inlet 21 of the liquid storage bin 2, the size of the outlet hole and the concentration of the cleaning liquid are controlled so that the cleaning liquid will not flow out of the outlet hole when the pneumatic device 5 is not started. For another example, the setting of the connecting cover 33 is not necessary. The connecting cover 33 can not be set, and the liquid outlet head 3 is inserted into the outlet hole to realize the connection and sealing between the liquid outlet pipe 32 and the inside of the liquid storage bin 2. Correspondingly, the convex edge 22 outside the outlet hole can also not be set. For another example, the conduit can not be set, and the lower end of the liquid outlet head 3 extends into the liquid storage bin 2. For another example, the fan-shaped groove 31 can not be set.

[0053] As Figure 4 and 6 shown, the support frame 4 is integrally formed with the liquid outlet head 3. A horizontally arranged long strip-shaped air outlet hole 42 is provided on the support frame 4. The air outlet hole 42 faces the liquid outlet head 3 and is located above the liquid outlet head 3. An installation cavity 41 communicating with the air outlet hole 42 is provided on the support frame 4. The air outlet pipe 53 of the pneumatic device 5 is inserted into the installation cavity 41, and the air outlet end of the pneumatic device 5 is communicated with the air outlet hole 42. In this way, the gas above the liquid outlet head 3 is accelerated through the air outlet hole 42, the air pressure above the liquid outlet head 3 is relatively low, and the cleaning liquid is pumped out from the liquid storage bin 2. And after the gas and the cleaning liquid are mixed, they are sprayed onto the roller brush in an atomized form, so that the roller brush uniformly contacts the cleaning liquid. The installation cavity 41 is convenient for connecting and fixing the air outlet pipe 53. The horizontally arranged long strip-shaped air outlet hole 42 can disperse the gas, so that the gas carries the cleaning liquid and contacts different positions of the roller brush.

[0054] It should be noted that the setting of the support frame 4 is not necessary. Those skilled in the art can choose whether to set the support frame 4 and the specific structure of the support frame 4 based on the specific application scenario. For example, the support frame 4 can be separately provided from the liquid outlet head 3, and the support frame 4 is connected to the upper side of the liquid storage chamber 2 by means of bonding, clamping or bolt connection. Another example is that the support frame 4 can also be connected to the main body 1 as long as the air outlet hole 42 can be set at an appropriate position. Another example is that the air outlet hole 42 can also be circular, square or polygonal, etc. Another example is that the air outlet hole 42 can be not provided, and the air outlet end of the pneumatic device 5 can be directly used to blow air at the upper end of the liquid outlet head 3. Correspondingly, the installation cavity 41 can be not provided, and the air outlet end of the pneumatic device 5 can be fixed to the support frame 4 by means of bonding or clamp connection. Another example is that the support frame 4 and the liquid outlet head 3 can be not provided, and the air outlet end of the pneumatic device 5 can be fixed to the upper side of the liquid storage chamber 2 by means of bonding or clamp connection.

[0055] Mainly refer to the appendix Figure 2 , the pneumatic device 5 includes an air pump 52 and a connecting seat 51. The air pump 52 is fixedly connected to the lower side of the main body 1 through the connecting seat 51, and the air outlet end of the air pump 52 is communicated with the air outlet hole 42 through an air outlet pipeline 53. Of course, other devices capable of compressing air can also be used. For example, an air pump 52 can be combined with an inflation chamber. The air pump 52 and the inflation chamber are both arranged on the lower side of the main body 1. The air pump 52 compresses air into the inflation chamber, and the inflation chamber is communicated with the air outlet hole 42 through an air outlet pipeline 53. A valve is arranged on the air outlet pipeline 53. When air supply to the air outlet hole 42 is required, the valve can be opened, and the inflation chamber can be inflated during non-use time, and the high-pressure gas in the inflation chamber can be directly used when in use. Another example is that a bicycle pump can be used. The bicycle pump is located on one side of the main body 1. When in use, an operator uses the bicycle pump to compress air. Another example is that a compressed gas cylinder can be used, and the air outlet pipeline 53 is communicated with the compressed gas cylinder, and the compressed gas in the compressed gas cylinder is directly used.

[0056] An alternative embodiment has one liquid storage chamber, which is arranged at the middle position of the main body 1, and the length direction of the liquid storage chamber is parallel to the length direction of the rolling brush. Four liquid outlet holes are arranged on the liquid storage chamber, each liquid outlet hole is communicated with a liquid outlet head, the length direction of the liquid outlet head is in an "S" shape, and two liquid outlet heads supply liquid to one rolling brush. The liquid outlet end of the liquid outlet head is located on one side of the liquid spraying groove 12. And the liquid outlet end of the liquid outlet head is connected to a support frame, the support frame is connected to the main body 1, a horizontally arranged long strip-shaped air outlet hole is arranged on the support frame, the air outlet hole faces the liquid outlet head and is located above the liquid outlet head, an installation cavity communicated with the air outlet hole is arranged on the support frame, and the air outlet pipeline of the pneumatic device 5 is inserted into the installation cavity. The air outlet end of the pneumatic device 5 is communicated with the air outlet hole. Other structures are the same as those of the preferred embodiment, and the usage method is also the same as that of the preferred embodiment. This embodiment can adaptively adjust the shape of the liquid outlet head according to the position of the liquid storage chamber, so as to realize supplying cleaning liquid to two cleaning grooves 11 by using one liquid storage chamber.

[0057] The present invention also discloses a floor cleaning equipment assembly, which includes a floor cleaning equipment and the above-mentioned base, and the lower part of the floor cleaning equipment can be placed in the placement groove. The air outlet end of the pneumatic device 5 is close to the upper end of the liquid outlet head 3 and faces the rolling brush on the upper side of the cleaning groove 11. When the air outlet end of the pneumatic device 5 discharges air, the air pressure at the upper end of the liquid outlet head 3 is lower, and the cleaning liquid in the liquid storage chamber 2 can be sprayed out from the upper end of the liquid outlet head 3 under the action of air pressure. The sprayed cleaning liquid is mixed with the gas under the action of the gas and is sprayed onto the rolling brush in an atomized form. Using the air pressure difference method to spray the cleaning liquid out of the liquid storage chamber 2 makes it more convenient to add the cleaning liquid to the rolling brush and has a better cleaning effect on the oil stains or dyes on the rolling brush.

[0058] The following introduces the possible operation modes of this embodiment.

[0059] When it is necessary to clean the rolling brush on the base, the air pump is started, and the compressed air of the air pump is sprayed out from the air outlet hole 42 through the air outlet pipeline 53. The air pressure at the upper end of the liquid outlet head 3 becomes smaller, and the cleaning liquid in the liquid storage chamber 2 reaches the upper end of the liquid outlet head 3 under the action of the atmospheric pressure through the conduit and the liquid outlet pipeline 32. The cleaning liquid at the upper end of the liquid outlet head 3 is mixed with the high-speed gas, and the cleaning liquid is in an atomized state and is sprayed onto the rolling brush. When the rolling brush has been evenly sprayed with the cleaning liquid, the air pump stops running.
