For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] Please refer to Figures 1 to 4 An embodiment of the utility model provides a cleaning liquid filling device, including a clean water tank 1, and a cleaning liquid filling mechanism 2 detachably arranged on the clean water tank 1, the cleaning liquid filling mechanism 2 includes a shell 21 detachably mounted on the clean water tank 1, and a pump head 22 arranged on the upper end surface of the shell 21 and extending downward.

[0028] By setting a cleaning liquid filling mechanism 2 on the clean water tank 1, the cleaning liquid and clean water can be stored independently to prevent the situation where the cleaning liquid and clean water are not used up and stratified over time, which affects the use effect. By setting the cleaning liquid filling mechanism 2 to include a shell 21 detachably mounted on the clean water tank 1 and a pump head 22 arranged on the upper end surface of the shell 21 and extending downward, when the cleaning liquid is needed, it is only necessary to press the pump head 22, and the pump head 22 can extract the cleaning liquid stored in the shell 21 and transport it into the clean water tank 1, and the amount of cleaning liquid flowing into the clean water tank 1 can be controlled by controlling the squeezing force of the pump head 22, so as to achieve a better fusion cleaning effect. The pressing structure setting is simple and convenient to operate, which effectively improves the user's use experience. The detachable structure also makes it convenient for users to replace the clean water tank 1 or the cleaning liquid filling mechanism 2 separately, which is easy to maintain.

[0029] Regarding the specific liquid discharge method of the cleaning liquid filling mechanism 2, as shown in FIG. Figure 2 As shown, the pump head 22 includes a pressure cover 221 arranged on the outer shell 21, a pressure rod 222 connected to the lower end of the pressure cover 221, a return spring 223 sleeved on one end of the pressure rod 222 close to the pressure cover 221, a first pipe 224 movably arranged on the outer side of the lower end of the pressure rod 222, a second pipe 225 which is overall in the shape of a Chinese character "" and one end of which is connected to the side wall of the first pipe 224, a liquid inlet piston 226 movably arranged at the other end of the second pipe 225, and a liquid outlet piston 227 movably arranged between the lower end of the first pipe 224 and the outer shell 21.

[0030] When it is necessary to add cleaning liquid into the clean water tank 1, it is only necessary to press the pressure cover 221 on the pump head 22, and the pressure cover 221 drives the pressure rod 222 arranged at its lower end to move downward, compressing the return spring 223, and the pressure rod 222 moves toward the lower end of the first pipe 224, squeezing the air in the first pipe 224, so that the pressure in the first pipe 224 and the second pipe 225 connected to the first pipe 224 becomes larger, forming a pressure difference with the air inside the shell 21, thereby generating an outward pushing force, pushing the liquid inlet piston 226, and the cleaning liquid enters the second pipe 225 and the first pipe 224 in sequence from the gap between the liquid inlet piston 226 and the second pipe 225. When the user releases the force of pressing the pressure cover 221, the reset spring 223, under the elastic action of its own elastic restoring force, drives the pressure cover 221 and the pressure rod 222 to move upward. At this time, the space between the first pipe 224 and the pressure rod 222 increases, the pressure in the space becomes smaller, and a pressure difference is formed with the air in the housing 21. An inward suction force is generated in the first pipe 224, thereby sucking up the liquid outlet piston 227. The cleaning liquid in the first pipe 224 is transported to the clean water tank 1 from the gap between the first pipe 224 and the liquid outlet piston 227 to complete the filling of the cleaning liquid. By changing the force of pressing the pressure cover 221, the size of the pressure difference in the first pipe 224 can be changed, thereby changing the amount of liquid suction and liquid discharge, so as to achieve the purpose of better controlling the amount of cleaning liquid filling. The whole structure is simple and clear, the components are closely matched, the operation is simple and convenient, and the user's experience is effectively improved.

[0031] The specific structural arrangement of the liquid inlet piston 226 and the liquid outlet piston 227 is as follows: Figure 2 As shown, the liquid inlet piston 226 and the liquid outlet piston 227 are both spherical, and the spherical shape makes it easier for the liquid inlet piston 226 and the liquid outlet piston 227 to be driven to move under the action of the pressure difference, thereby improving the efficiency of the liquid inlet and liquid outlet of the pump head 22. In addition, this structure is a conventional universal part in the technical field of the pump head 22, and its price is low, and no separate mold is required, etc., which effectively reduces the production cost of the device.

[0032] Regarding the specific structural arrangement of the housing 21, Figures 1 to 3 As shown, the housing 21 includes a lower housing 211 snap-fitted to the clean water tank 1, and an upper housing 212 disposed on the lower housing 211. The upper housing 212 and the lower housing 211 are fixedly connected, thereby effectively preventing the cleaning liquid from leaking from the housing 21.

[0033] Regarding the specific structural arrangement of the lower shell 211, as shown in FIG. Figure 3As shown, an extension groove 2111 extends downward from the lower end of the lower shell 211, and at least one shell clamping block 2112 is provided on the outer wall of the extension groove 2111. The shell clamping block 2112 is clamped to the upper part of the clean water tank 1, so that the cleaning liquid filling mechanism 2 is clamped and installed on the clean water tank 1. The lower end surface of the inner part of the extension groove 2111 is formed with a liquid outlet clamping platform 2113 extending upward and extending into the lower end surface of the first pipe 224. The liquid outlet piston 227 moves on the liquid outlet clamping platform 2113. The lower end of the liquid outlet clamping platform 2113 is formed with a first liquid outlet 2114 for the cleaning liquid to flow out into the clean water tank 1. When the liquid needs to be discharged, the liquid outlet piston 227 is driven away from the lower end surface of the liquid outlet clamping platform 2113, so that the cleaning liquid sucked into the first pipe 224 flows from the gap between the liquid outlet piston 227 and the first pipe 224 to the first liquid outlet 2114, and is transported from the first liquid outlet 2114 to the clean water tank 1 to complete the filling of the cleaning liquid. The whole structure is simple and clear, the various components are closely matched, the operation is simple and convenient, and the user's experience is effectively improved.

[0034] Regarding the specific structural arrangement of the upper shell 212, as shown in FIG. Figure 2 As shown, a pressing groove 2121 is formed in the middle of the upper end of the upper shell 212 for the movement of the pressing cover 221 and the pressing rod 222. The upper end of the return spring 223 presses on the pressing rod 222, and the lower end presses on the lower end surface of the pressing groove 2121. When the user presses the pressing cover 221, the pressing cover 221 drives the pressing rod 222 arranged thereon to move downward in the pressing groove 2121, and the upper end of the return spring 223 receives the downward pressing force of the lower end surface of the pressing rod 222. Since the lower end of the return spring 223 is fixedly pressed on the lower end surface of the pressing groove 2121, the return spring 223 itself is compressed and deformed, and the pressing rod 222 presses down in the first pipe 224, so that the first pipe 22 4 becomes larger, thereby completing the liquid absorption. When the user releases the pressure cover 221, the return spring 223, under its own elastic restoring force, since the lower end of the return spring 223 is fixed below the lower end surface of the inner part of the pressing groove 2121, the return spring 223 rebounds the pressure rod 222 upward, so that the pressure rod 222 moves up, driving the pressure cover 221 to reset. At the same time, since the pressure rod 222 moves up in the first pipe 224, the pressure in the first pipe 224 and the second pipe 225 is reduced, thereby completing the operation of injecting the cleaning liquid in the first pipe 224 into the clean water tank 1. The whole structure is simple and clear, the various components cooperate closely, the operation is simple and convenient, and the user's experience is effectively improved.

[0035] Regarding the specific method of the pressing rod 222 moving in the pressing groove 2121, as shown in FIG. Figure 2As shown, a movable channel 2122 extending upward is formed on the lower end surface of the pressing groove 2121 , the pressing rod 222 moves in the movable channel 2122 , and the return spring 223 is sleeved on the outer side of the movable channel 2122 .

[0036] Regarding the specific structural arrangement of the pressure rod 222, as shown in FIG. Figure 2 As shown, the pressing rod 222 is in a "T" shape as a whole, the pressing cover 221 is fixed to the upper end of the pressing rod 222, the upper part of the pressing rod 222 moves in the pressing groove 2121, and the lower part of the pressing rod 222 passes through the lower end of the pressing groove 2121 and extends into the first pipe 224. The pressing rod 222 is in a "T" shape as a whole, so that the contact area between the upper end of the pressing rod 222 and the pressing cover 221 is large, and the force area of ​​the user's downward pressure is increased, so that the downward pressure is more uniform, which is conducive to the coordination between various components.

[0037] Preferably, Figure 2 As shown, a limit ring 2221 extending outward is also provided on the middle outer wall of the pressure rod 222. The limit ring 2221 presses against the bottom surface of the pressing groove 2121 when there is no external force pressing the pressure rod 222. When the user presses the pressure rod 222, the limit ring 2221 moves downward as a whole following the pressure rod 222. When used to release the pressure rod 222, the limit ring 2221 moves upward as a whole following the pressure rod 222 driven by the return spring 223, thereby pressing against the bottom surface of the pressing groove 2121, thereby limiting the stroke of the pressure rod 222 and preventing the pressure rod 222 from moving upward excessively.

[0038] Preferably, Figure 2 As shown, at least one buffer ring 2222 is respectively sleeved on the upper outer wall and the lower outer wall of the pressure rod 222. By setting the buffer ring 2222 on the upper outer wall of the pressure rod 222, the movement of the pressure rod 222 in the pressing groove 2121 is slowed down, thereby preventing the user from accidentally pressing all the way down, and making it easier for the user to accurately control the force of pressing down, thereby accurately controlling the dosage of the cleaning liquid to be added, avoiding the problem of excessive injection of the cleaning liquid, and achieving a better fusion cleaning effect. By setting the buffer ring 2222 on the lower outer wall of the pressure rod 222, the action of the pressure rod 222 pressing down on the first pipe 224 is slowed down, thereby accurately controlling the force of pressing down on the air in the first pipe 224, making it easier to control the internal and external pressure difference, and then accurately controlling the dosage of the cleaning liquid to be added, reducing waste.

[0039] Regarding the specific movement of the liquid outlet piston 227, Figure 2As shown, the pump head 22 further includes a liquid outlet pressing member 228 disposed between the first pipe 224 and the liquid outlet clamping platform 2113, and the upper end of the liquid outlet pressing member 228 is provided with a second liquid outlet 2281 for the cleaning liquid to flow out, and the liquid outlet piston 227 moves between the lower end of the liquid outlet pressing member 228 and the liquid outlet clamping platform 2113. When the pressure in the first pipe 224 increases, a pressure difference is formed between the inside and the outside of the first pipe 224, so that the first pipe 224 is The two ends of 224 generate an outward thrust, and the liquid outlet piston 227 is pushed from the pressure inside the second liquid outlet 2281 to the lower end of the liquid outlet pressure piece 228 and the liquid outlet clamping platform 2113. The cleaning liquid in the first pipe 224 flows from the second liquid outlet 2281 into the liquid outlet pressure piece 228 and the liquid outlet clamping platform 2113, and is injected into the clean water tank 1 through the first liquid outlet 2114 at the lower end of the liquid outlet clamping platform 2113. When the pressure inside the first pipe 224 decreases or is not in use, a pressure difference is formed between the inside and outside of the first pipe 224, so that the two ends of the first pipe 224 generate an inward suction force. Under the attraction of the suction force, the liquid outlet piston 227 moves upward to block the second liquid outlet 2281, thereby preventing the cleaning liquid filling mechanism 2 from leaking. The entire structure is simple and clear, the components are tightly matched, the operation is simple and convenient, and the manufacturing cost is low.

[0040] Regarding the specific movement of the liquid inlet piston 226, Figure 2 As shown, the pump head 22 also includes a liquid inlet pressure piece 229 arranged at the lower end of the second pipe 225, and the lower end of the liquid inlet pressure piece 229 is provided with a first liquid inlet 2291 for the cleaning liquid to enter, and the liquid inlet piston 226 moves between the inside of the liquid inlet pressure piece 229 and the inside of the lower end of the second pipe 225. When the pressure in the first pipe 224 and the second pipe 225 becomes smaller, a pressure difference is formed between the first pipe 224 and the second pipe 225, so that an inward suction force is generated in the first pipe 224 and the second pipe 225. Under the attraction of the suction force, the liquid inlet piston 226 moves upward, so that the liquid inlet piston 226 originally pressed against the first liquid inlet port 2291 is lifted to a position between the liquid inlet pressing member 229 and the lower end of the second pipe 225. Under the action of the pressure difference, the cleaning liquid in the housing 21 is sucked into the second pipe 225 and the first pipe 224 from the first liquid inlet port 2291 in turn. No manual addition is required, freeing both hands, and the various accessories are tightly matched, and the operation is simple and convenient.

[0041] Regarding the feeding method of the cleaning liquid filling mechanism 2, as Figure 4As shown, the cleaning liquid filling mechanism 2 also includes a feeding assembly 23 disposed on the upper shell 212, and the feeding assembly 23 includes a feeding groove 231 disposed on the upper shell 212, a feeding port 232 opened at one end of the feeding groove 231, a feeding plug mounting groove 233 opened at the other end of the feeding groove 231, and a feeding plug 234 rotatably disposed in the feeding plug mounting groove 233 and covering the feeding port 232. When it is necessary to add cleaning liquid to the cleaning liquid filling mechanism 2, it is only necessary to pull out the feeding plug 234, and one end of the feeding plug 234 rotates on the feeding plug mounting groove 233 with the feeding plug mounting groove 233 as the center, so that the end of the feeding plug 234 covering the feeding port 232 leaves the feeding port 232, and the user can freely add cleaning liquid to the cleaning liquid filling mechanism 2. After adding, it is only necessary to rotate the feeding plug 234 so that the feeding plug 234 is re-covered on the feeding port 232. The whole operation is simple and convenient, and the cleaning liquid is stored and added independently, which avoids the stratification of the cleaning liquid and the clean water, and effectively improves the user's experience.

[0042] The specific method of rotating the feed plug 234 in the feed plug installation slot 233 is as follows: Figure 4 As shown, the feeding plug 234 is located on the lower end surface of one end of the feeding plug installation groove 233 and has a downwardly extending rotating shaft 2342 formed thereon. The rotating shaft 2342 is inserted into the feeding plug installation groove 233 so that the feeding plug 234 can be rotated around the rotating shaft 2342 to be separated from the feeding port 232.

[0043] Preferably, Figure 1 , Figure 3 and Figure 4 As shown, a handle 2341 is formed on one end of the feeding plug 234 close to the feeding port 232 and is attached to the outer wall of the shell 21. When the user wants to add cleaning liquid to the cleaning liquid filling mechanism 2, he only needs to lift the handle 2341 to pull the feeding plug 234 out of the feeding port 232. The whole operation is simple and convenient, which further improves the user experience.

[0044] Regarding the specific method of connecting the clean water tank 1 and the cleaning liquid filling mechanism 2, as shown in FIG. Figure 2 and Figure 3As shown, the upper end surface of the clean water tank 1 is provided with a mounting groove 11 matching the extension groove 2111, and the side of the mounting groove 11 is provided with a clean water tank 1 clamping block clamped on the housing 21 clamping block. The extension groove 2111 is correspondingly inserted into the mounting groove 11, and the cleaning liquid filling mechanism 2 is rotated so that the housing 21 clamping block on the extension groove 2111 and the clean water tank 1 clamping block are mutually engaged, thereby completing the stable installation of the cleaning liquid filling mechanism 2 on the clean water tank 1. The whole structure is simple and clear, the operation is simple and convenient, and the stability is high, which improves the reliability of the device.

[0045] The specific method of adding the cleaning liquid in the cleaning liquid filling mechanism 2 into the clean water tank 1 is as follows: Figure 2 As shown, the installation groove 11 is provided with a second liquid inlet 13 extending toward the inside of the clean water tank 1 at a position corresponding to the first liquid outlet 2114. After the cleaning liquid comes out of the first liquid outlet 2114, it directly flows into the second liquid inlet 13 under the action of gravity, and then enters the clean water tank 1 to mix with the clean water in the clean water tank 1, so that the cleaning effect of the floor scrubber is better.
