Description

Technical Field

[0001] The present application relates to the field of cleaning, and in particular to a portable cleaning device, a cleaning method and a cleaning liquid. Background Art

[0002] In daily life, clothes, ties, scarves, gloves and other clothing are often easily stained with stains, such as oil stains, ink, dust, etc. In particular, students are prone to accidentally draw on their clothes when using pens. If such ink stains are not dealt with in time, it will be difficult to clean them over time, leaving deep and shallow marks on the clothes. In addition, when attending important occasions such as banquets or business negotiations, if clothes are accidentally stained with stains, if they are not dealt with in time, it will affect our image.

[0003] However, when washing clothes with the washing equipment in the prior art, the clothes need to be completely wetted, which not only takes a long time to wash, but also is not easy to dry, and is difficult to adapt to rapid washing. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a portable cleaning device, a cleaning method and a cleaning liquid, which are intended to improve the problem in the related art that the clothes need to be completely wet when they are washed.

[0005] In the first aspect, an embodiment of the present application provides a portable cleaning device, which includes a liquid reservoir, a liquid outlet head, a liquid outlet pipe, a pumping device, a liquid return head and a liquid return pipe, wherein the liquid reservoir is used to store cleaning liquid; the liquid outlet pipe is used to connect the liquid reservoir and the liquid outlet head; the liquid return pipe is used to connect the liquid return head and the pumping device; wherein the liquid return head and the liquid outlet head are used to cooperate to clamp the to-be-cleaned position of the to-be-cleaned item so that the liquid outlet pipe and the liquid return pipe form a passage.

[0006] In the above technical scheme, the liquid discharge head and liquid return head of the portable cleaning device can be clamped in the position to be cleaned, so that the liquid discharge pipe and the liquid return pipe form a passage. Through the suction action of the pumping device, it can provide power to supply the cleaning liquid stored in the liquid reservoir through the liquid discharge pipe to the liquid discharge head, and the liquid discharge head sprays the cleaning liquid to the position to be cleaned. The liquid return head sucks away part of the cleaning liquid at the position to be cleaned to form a flushing passage, continuously supplies the cleaning liquid to the position to be cleaned, and flushes the position to be cleaned. The excess cleaning liquid is taken away by the liquid return head, and will not wet the parts to be cleaned in a large area. It can be seen that the portable cleaning device can avoid wetting all the parts to be cleaned, and can only clean the position to be cleaned, and the cleaning is fast and convenient. In addition, since the structure of the portable cleaning device provided in the embodiment of the present application is relatively simple, the portable cleaning device can be made small enough to facilitate carrying and use at any time. Furthermore, when the portable cleaning device is used to clean the parts to be cleaned, the stains are dissolved by the cleaning liquid and taken away, without physical friction, and the parts to be cleaned will not be damaged.

[0007] As an optional technical solution of an embodiment of the present application, the liquid outlet head has a first large end and a first small end that are interconnected, and the first small end is connected to the liquid outlet pipe; the liquid return head has a second large end and a second small end that are interconnected, and the second small end is connected to the pumping device; the first large end and the second large end are used to cooperate in clamping the cleaning position of the cleaned item.

[0008] In the above technical solution, the cleaning liquid flowing from the liquid outlet pipe to the first small end gradually diffuses in the process of passing through the first small end to reach the first large end, so that the cleaning liquid can spray a larger area to adapt to the larger area of ​​the position to be cleaned. In other words, the liquid outlet head can increase the spraying area of ​​the cleaning liquid while facilitating the discharge of liquid. Correspondingly, the liquid return head needs to suck the cleaning liquid in the position to be cleaned with a larger area. Therefore, the second large end of the liquid return head cooperates with the first large end of the liquid outlet head to clamp the position to be cleaned, so as to facilitate the suction and collection of the cleaning liquid in the position to be cleaned. After collection, the cleaning liquid flows from the second large end to the second small end and is taken away through the liquid return pipe. The liquid outlet head having the first large end and the first small end is provided to help reduce the diameter of the liquid outlet pipe. The liquid return head having the second large end and the second small end is provided to help reduce the diameter of the liquid return pipe.

[0010] In the above technical solution, by selecting a suction cup as the liquid outlet head and / or the liquid return head, on the one hand, the suction cup itself has a large end and a small end, which can diffuse or collect the cleaning liquid. On the other hand, the suction cup can be adsorbed on the part to be cleaned to position the liquid outlet head and the liquid return head on the part to be cleaned, ensuring that the liquid outlet pipe and the liquid return pipe maintain a passage during use. Positioning by suction cup adsorption can also reduce the labor intensity of manually positioning the liquid outlet head and the liquid return head, further improving the convenience of use.

[0011] As an optional technical solution of an embodiment of the present application, the portable cleaning device includes a first matching component and a second matching component, the first matching component is connected to the liquid outlet head; the second matching component is connected to the liquid return head, and the second matching component is used to cooperate with the first matching component to respectively position the liquid outlet head and the liquid return head on both sides of the position to be cleaned.

[0012] In the above technical solution, through the mutual cooperation of the first matching part and the second matching part, the liquid outlet head and the liquid return head are respectively positioned on both sides of the position to be cleaned, ensuring that the liquid outlet pipe and the liquid return pipe maintain a passage during use, reducing the labor intensity of manually positioning the liquid outlet head and the liquid return head, and further improving the convenience of use.

[0013] As an optional technical solution of the embodiment of the present application, the first matching piece and the second matching piece are both magnetic parts.

[0014] In the above technical solution, magnetic suction parts are selected as the first matching part and the second matching part to achieve magnetic attraction of the first matching part and the second matching part, so as to facilitate positioning the liquid discharge head and the liquid return head on both sides of the position to be cleaned.

[0015] As an optional technical solution of an embodiment of the present application, the portable cleaning device includes a clamping member, the clamping member having a first clamping arm and a second clamping arm, the first clamping arm is hinged to the second clamping arm, the first clamping arm is connected to the liquid outlet head, the second clamping arm is connected to the liquid return head, the first clamping arm and the second clamping arm are used to cooperate and clamp at the position to be cleaned so as to respectively position the liquid outlet head and the liquid return head on both sides of the position to be cleaned.

[0016] In the above technical solution, by connecting the liquid outlet head to the first clamping arm and connecting the liquid return head to the second clamping arm, when the clamping member is clamped at the position to be cleaned, that is, when the first clamping arm and the second clamping arm are cooperatively clamped at the position to be cleaned, the liquid outlet head and the liquid return head can be positioned on both sides of the position to be cleaned, ensuring that the liquid outlet pipe and the liquid return pipe maintain passage during use, reducing the labor intensity of manually positioning the liquid outlet head and the liquid return head, and improving convenience of use.

[0017] As an optional technical solution of an embodiment of the present application, the portable cleaning device includes a first positioning member and a second positioning member, the first positioning member is connected to the liquid discharge head, and the first positioning member is used to connect with the part to be cleaned to position the liquid discharge head on one side of the position to be cleaned; the second positioning member is connected to the liquid return head, and the second positioning member is used to connect with the part to be cleaned to position the liquid discharge head on the other side of the position to be cleaned.

[0018] In the above technical solution, the first positioning member is provided to position the liquid outlet head on one side of the position to be cleaned, and the second positioning member is provided to position the liquid return head on the other side of the part to be cleaned, thereby ensuring that the liquid outlet pipe and the liquid return pipe maintain a passage during use, reducing the labor intensity of manually positioning the liquid outlet head and the liquid return head, and improving the convenience of use.

[0019] As an optional technical solution of an embodiment of the present application, the portable cleaning device includes a switching device, which has a first state and a second state. When the switching device is in the first state, the liquid outlet pipe is connected to the atmosphere; when the switching device is in the second state, the liquid outlet pipe is disconnected from the atmosphere.

[0020] In the above technical solution, by setting a switching device, when cleaning the position to be cleaned, the switching device is switched to the second state, so that the liquid outlet pipe is disconnected from the atmosphere, and the pumping device can supply the cleaning liquid in the liquid reservoir to the liquid outlet head through the liquid outlet pipe to clean the position to be cleaned. After the cleaning is completed, the switching device can be switched to the first state, so that the liquid outlet pipe is connected to the atmosphere. At this time, the air in the atmosphere is sucked into the liquid outlet pipe under the action of the pumping device, and discharged from the liquid outlet head to air-dry the position to be cleaned, thereby accelerating the drying of the position to be cleaned.

[0021] As an optional technical solution of an embodiment of the present application, the switching device is connected to the liquid reservoir and the liquid outlet pipe. When the switching device is in the first state, the liquid outlet pipe is connected to the atmosphere, and the liquid reservoir is disconnected from the liquid outlet pipe; when the switching device is in the second state, the liquid outlet pipe is disconnected from the atmosphere, and the liquid reservoir is connected to the liquid outlet pipe.

[0022] In the above technical solution, by connecting the switching device to the liquid reservoir and the liquid outlet pipe, when the switching device is in the first state, the liquid outlet pipe is connected to the atmosphere and disconnected from the liquid reservoir, thereby preventing the cleaning liquid in the liquid reservoir from being sucked into the liquid outlet head when the position to be cleaned is air-dried.

[0023] As an optional technical solution of the embodiment of the present application, the pumping device is connected to the liquid reservoir.

[0024] In the above technical solution, by connecting the pumping device with the liquid reservoir, when using the portable cleaning device, the cleaning liquid sucked by the liquid return head does not need to be discharged to the outside, thereby avoiding pollution to the external environment.

[0025] In the second aspect, an embodiment of the present application also provides a cleaning method, based on the above-mentioned portable cleaning device, the cleaning method includes clamping the to-be-cleaned position of the to-be-cleaned part by the cooperation of the liquid return head and the liquid outlet head; starting the pumping device to spray the cleaning liquid in the liquid reservoir from the liquid outlet head to the to-be-cleaned position, and sucking the cleaning liquid from the liquid return head.

[0027] In the above technical solution, the cleaning liquid has a good cleaning effect and is easy to evaporate. Therefore, after the cleaning position is cleaned with the above-mentioned portable cleaning device, the cleaning liquid can evaporate quickly without drying, and will not remain on the items to be cleaned or spread on the items to be cleaned.

[0046] Example

[0047] Please refer to Figure 1 The present embodiment provides a portable cleaning device 10, which includes a liquid reservoir 100, a liquid outlet head 200, a liquid outlet pipe 300, a pumping device 400, a liquid return head 500 and a liquid return pipe 600. The liquid reservoir 100 is used to store cleaning liquid. The liquid outlet pipe 300 is used to connect the liquid reservoir 100 and the liquid outlet head 200. The liquid return pipe 600 is used to connect the liquid return head 500 and the pumping device 400. The liquid return head 500 and the liquid outlet head 200 are used to cooperate with each other to clamp the position to be cleaned of the to-be-cleaned object, so that the liquid outlet pipe 300 and the liquid return pipe 600 form a passage.

[0048] The liquid reservoir 100 is a vessel or structure for storing cleaning liquid. The liquid reservoir 100 can be a bottle, a box, a box, a tank, etc. In some embodiments, the liquid reservoir 100 is a bottle. Choosing a bottle as the liquid reservoir 100 is not only low in cost and easy to carry, but also the cleaning liquid stored in the bottle is not easy to spill out and not easy to cause pollution.

[0049] The liquid outlet head 200 is a component for receiving the cleaning liquid delivered by the liquid outlet pipe 300 and spraying it to the position to be cleaned. The liquid return head 500 is a component for collecting the cleaning liquid at the position to be cleaned. The pumping device 400 is a pump body structure that provides power for the portable cleaning device 10.

[0050] The liquid discharge head 200 and the liquid return head 500 of the portable cleaning device 10 can cooperate and be clamped at the position to be cleaned, so that the liquid discharge pipe 300 and the liquid return pipe 600 form a passage. Through the suction action of the pumping device 400, it can provide power to supply the cleaning liquid stored in the liquid reservoir 100 to the liquid discharge head 200 through the liquid discharge pipe 300, and the cleaning liquid is sprayed to the position to be cleaned by the liquid discharge head 200. The liquid return head 500 sucks away part of the cleaning liquid at the position to be cleaned to form a flushing passage, continuously supplies the cleaning liquid to the position to be cleaned, and flushes the position to be cleaned. The excess cleaning liquid is taken away by the liquid return head 500, and will not wet the parts to be cleaned over a large area. It can be seen that the portable cleaning device 10 can avoid wetting all the parts to be cleaned, and can only clean the position to be cleaned, which is quick and convenient.

[0051] In addition, since the structure of the portable cleaning device 10 provided in this embodiment is relatively simple, the portable cleaning device 10 can be made small enough to be carried around and used at any time.

[0052] Furthermore, when the portable cleaning device 10 is used to clean the items to be cleaned, the cleaning liquid dissolves the stains and carries them away without any physical friction and without damaging the items to be cleaned.

[0053] In some embodiments, please refer to Figure 1 The portable cleaning device 10 includes a drain pipe 700, one end of which is connected to the pumping device 400, and the drain pipe 700 is used to discharge the cleaning liquid collected by the liquid return head 500 to the outside, for example, to a sewage tank. Optionally, the pumping device 400 includes an inlet and an outlet, wherein the inlet is connected to the end of the liquid return pipe 600 away from the liquid return head 500, and the outlet is connected to one end of the drain pipe 700, and the other end of the drain pipe 700 is used to extend to the sewage tank. The cleaning liquid collected by the liquid return head 500 passes through the liquid return pipe 600 and the pumping device 400, and is discharged through the drain pipe 700. In this way, the excess cleaning liquid is taken away by the liquid return head 500 and discharged to the outside, and it is not easy to wet places other than the position to be cleaned.

[0054] Please refer to Figure 2 In some embodiments, the pumping device 400 is connected to the liquid reservoir 100. Specifically, the portable cleaning device 10 includes a return pipe 800, one end of which is connected to the liquid reservoir 100, and the other end of which is connected to the pumping device 400. By connecting the pumping device 400 to the liquid reservoir 100, when the portable cleaning device 10 is used, the cleaning liquid sucked by the liquid return head 500 does not need to be discharged to the outside, thereby avoiding pollution to the external environment and reducing the demand for structures such as sewage tanks in the external environment.

[0055] Please refer to Figure 3 In some embodiments, the portable cleaning device 10 includes a pressure relief valve 110, which is connected to the liquid reservoir 100 and is used to control the connection and disconnection between the liquid reservoir 100 and the atmosphere. When the pressure relief valve 110 is opened, the liquid reservoir 100 is connected to the atmosphere; when the pressure relief valve 110 is closed, the liquid reservoir 100 is disconnected from the atmosphere. When the liquid return head 500 sucks the cleaning liquid, the air in the atmosphere will also be sucked into the liquid reservoir 100, thereby increasing the atmospheric pressure in the liquid reservoir 100, causing the pressure of the liquid outlet head 200 to increase, which may cause the cleaning liquid to seep out and spread on the parts to be cleaned. Therefore, by setting the pressure relief valve 110, when cleaning the position to be cleaned, the pressure relief valve 110 is opened so that the pressure in the liquid reservoir 100 is balanced with the atmospheric pressure. In this way, it is possible to avoid excessive pressure in the liquid outlet head 200, which may cause the cleaning liquid to seep out and spread on the parts to be cleaned. When the parts to be cleaned are not cleaned, the pressure relief valve 110 is closed to prevent leakage of the cleaning liquid.

[0056] Please refer to Figure 4 In some embodiments, the portable cleaning device 10 includes a switching device 310. The switching device 310 has a first state and a second state. When the switching device 310 is in the first state, the liquid outlet pipe 300 is connected to the atmosphere; when the switching device 310 is in the second state, the liquid outlet pipe 300 is disconnected from the atmosphere.

[0057] Optionally, the liquid outlet pipe 300 is connected to a branch pipe communicating with the atmosphere, and the switching device 310 is a valve disposed on the branch pipe.

[0058] By setting the switching device 310, when cleaning the position to be cleaned, the switching device 310 is switched to the second state, so that the liquid outlet pipe 300 is disconnected from the atmosphere, and the pumping device 400 can supply the cleaning liquid in the liquid reservoir 100 to the liquid outlet head 200 through the liquid outlet pipe 300 to clean the position to be cleaned. After the cleaning is completed, the switching device 310 can be switched to the first state, so that the liquid outlet pipe 300 is connected to the atmosphere. At this time, the air in the atmosphere is sucked into the liquid outlet pipe 300 under the action of the pumping device 400, and discharged from the liquid outlet head 200 to air dry the position to be cleaned, thereby accelerating the drying of the position to be cleaned.

[0059] When the switching device 310 is in the first state, since the liquid outlet pipe 300 is connected to the atmosphere, the power provided by the pumping device 400 is mainly used to suck the air in the atmosphere. Although the liquid outlet pipe 300 is connected to the liquid reservoir 100, the suction force of the liquid outlet pipe 300 on the cleaning liquid in the liquid reservoir 100 is not enough to overcome the gravity of the cleaning liquid. Therefore, when the switching device 310 is in the first state, the liquid outlet pipe 300 will not suck the cleaning liquid in the liquid reservoir 100 to the liquid outlet head 200, but will only suck the air in the atmosphere to the liquid outlet head 200 to air dry the position to be cleaned.

[0060] In other embodiments, an air extraction hole is provided on the liquid outlet pipe 300, and the switching device 310 is a plug for blocking the air extraction hole. When the switching device 310 blocks the air extraction hole, the switching device 310 is in the second state. When the switching device 310 is pulled out, that is, when the switching device 310 does not block the air extraction hole, the switching device 310 is in the first state.

[0061] During use, the liquid reservoir 100 may tilt or invert. At this time, the cleaning liquid in the liquid reservoir 100 may flow into the liquid outlet pipe 300 and then be discharged from the liquid outlet head 200, resulting in the phenomenon of air drying and liquid discharge at the same time, which reduces the air drying effect. Figure 5 In some embodiments, the switching device 310 is connected to the liquid reservoir 100 and the liquid outlet pipe 300. When the switching device 310 is in a first state, the liquid outlet pipe 300 is connected to the atmosphere, and the liquid reservoir 100 is disconnected from the liquid outlet pipe 300; when the switching device 310 is in a second state, the liquid outlet pipe 300 is disconnected from the atmosphere, and the liquid reservoir 100 is connected to the liquid outlet pipe 300.

[0062] By connecting the switching device 310 to the liquid reservoir 100 and the liquid outlet pipe 300, when the switching device 310 is in the first state, the liquid outlet pipe 300 is connected to the atmosphere and disconnected from the liquid reservoir 100, thereby preventing the cleaning liquid in the liquid reservoir 100 from being sucked into the liquid outlet head 200 when the position to be cleaned is air-dried.

[0063] In some embodiments, the switching device 310 is a three-way valve. In other embodiments, the switching device 310 may also be a four-way valve, a five-way valve, etc.

[0064] Please refer to Figure 6 In some embodiments, the liquid outlet head 200 has a first large end 210 and a first small end 220 that are interconnected, and the first small end 220 is connected to the liquid outlet pipe 300. The liquid return head 500 has a second large end 510 and a second small end 520 that are interconnected, and the second small end 520 is connected to the pumping device 400. The first large end 210 and the second large end 510 are used to cooperate with the position to be cleaned of the object to be cleaned.

[0065] The first large end 210 is a larger end of the liquid outlet head 200, and the first small end 220 is a smaller end of the liquid outlet head 200. The first large end 210 is connected to the first small end 220. Optionally, in the direction from the first small end 220 to the first large end 210, the size of the liquid outlet head 200 gradually increases.

[0066] In some embodiments, the liquid outlet head 200 is in a conical cylindrical shape, and the diameter of the liquid outlet head 200 gradually increases from the first small end 220 to the first large end 210 in the axial direction of the liquid outlet head 200. In some embodiments, the liquid outlet head 200 is in a square conical cylindrical shape, and the side length of the cross section of the liquid outlet head 200 gradually increases from the first small end 220 to the first large end 210 in the axial direction of the liquid outlet head 200.

[0067] The second large end 510 is a larger end of the liquid return head 500, and the second small end 520 is a smaller end of the liquid return head 500, and the second large end 510 is connected to the second small end 520. Optionally, in the direction from the second small end 520 to the second large end 510, the size of the liquid return head 500 gradually increases.

[0068] In some embodiments, the liquid return head 500 is in a conical cylindrical shape, and the diameter of the liquid return head 500 gradually increases from the second small end 520 to the second large end 510 in the axial direction of the liquid return head 500. In some embodiments, the liquid return head 500 is in a square conical cylindrical shape, and the side length of the cross section of the liquid outlet head 200 gradually increases from the first small end 220 to the first large end 210 in the axial direction of the liquid return head 500.

[0069] The cleaning liquid flowing from the liquid outlet pipe 300 to the first small end 220 gradually spreads in the process of passing through the first small end 220 to reach the first large end 210, so that the cleaning liquid can spray a larger area to adapt to the larger area of ​​the position to be cleaned. In other words, the liquid outlet head 200 can increase the spraying area of ​​the cleaning liquid while facilitating the discharge of liquid. Correspondingly, the liquid return head 500 needs to suck the cleaning liquid in the position to be cleaned in a larger area. Therefore, the second large end 510 of the liquid return head 500 cooperates with the first large end 210 of the liquid outlet head 200 to clamp the position to be cleaned, so as to facilitate the suction and collection of the cleaning liquid in the position to be cleaned. After collection, the cleaning liquid flows from the second large end 510 to the second small end 520 and is taken away through the liquid return pipe 600. The liquid outlet head 200 having the first large end 210 and the first small end 220 is provided to help reduce the diameter of the liquid outlet pipe 300. The provision of the liquid return head 500 having the second large end 510 and the second small end 520 is helpful to reduce the diameter of the liquid return pipe 600 .

[0070] In some embodiments, the liquid discharge head 200 and / or the liquid return head 500 is a suction cup.
