[0040] Reference Figures 1 to 5 This utility model provides a liquid adding device, including a housing 1 and a pressing assembly 2 installed on the housing 1. The housing 1 has a liquid inlet, a liquid outlet 15 and a first receiving cavity 11 for storing cleaning agent. The liquid inlet is connected to the first receiving cavity 11, and cleaning agent is injected into the first receiving cavity 11 through the liquid inlet. A first one-way valve 3 is provided at the liquid inlet. The first receiving cavity 11 is connected to the liquid outlet 15 through the pressing assembly 2, and the cleaning agent in the first receiving cavity 11 is discharged through the liquid outlet 15 by pressing the pressing assembly 2.

[0041] In practice, the liquid adding device is integrated with the clean water tank. When it is necessary to add cleaning agent to the clean water tank, pressing the pressing component 2 can discharge the cleaning agent in the first receiving chamber 11 into the clean water tank through the liquid outlet 15, thus enabling convenient and quick addition of cleaning agent to the clean water tank without requiring the user to remove the clean water tank to add cleaning agent, thereby improving the user experience.

[0042] In some embodiments, the housing 1 also has a second receiving cavity 12, and the pressing component 2 is partially disposed in the second receiving cavity 12 and communicates with the first receiving cavity 11 and the liquid outlet 15 respectively through corresponding pipes (not shown) or flow channels (not shown), so that the cleaning agent in the first receiving cavity 11 can be discharged through the liquid outlet 15 after pressing the pressing component 2.

[0043] In some embodiments, the liquid dispensing device further includes a second one-way valve 4 disposed in the second receiving cavity 12. One end of the second one-way valve 4 is connected to the first receiving cavity 11, and the other end of the second one-way valve 4 is connected to the pressing assembly 2, so that the cleaning agent can only flow unidirectionally from the first receiving cavity 11 to the pressing assembly 2.

[0044] In some embodiments, the liquid dispensing device further includes a third one-way valve 5 disposed in the second receiving cavity 12. One end of the third one-way valve 5 is connected to the pressing assembly 2, and the other end of the third one-way valve 5 is connected to the liquid outlet 15, so that the cleaning agent can only flow in one direction toward the liquid outlet 15.

[0045] Furthermore, the second one-way valve 4 is connected to the pressing assembly 2 and the first receiving cavity 11 via a pipe, which can be a flexible silicone tube or the like. Similarly, the third one-way valve 5 is connected to the pressing assembly 2 and the liquid outlet 15 via a pipe, which can also be a flexible silicone tube or the like.

[0046] In some embodiments, the pressing assembly 2 includes a housing 21, a button 22, a three-way connector 23, and a reset connector 24.

[0047] The housing 21 has a travel cavity 210. The button 22 is at least partially movably disposed in the travel cavity 210, and the portion of the button 22 located in the travel cavity 210 is in close contact with the cavity wall of the travel cavity 210. A three-way connector 23 is connected to the housing 21 and disposed in the second receiving cavity 12. The three-way connector 23 has a first channel 231, a second channel 232, and a third channel 233 that are interconnected. The first channel 231 communicates with the first receiving cavity 11, the second channel 232 communicates with the travel cavity 210, and the third channel 233 communicates with the liquid outlet 15. A reset member 24 is disposed between the housing 21 and the button 22 for resetting the button 22.

[0048] Furthermore, the portion of button 22 located in the travel cavity 210 is tightly fitted to the cavity wall of the travel cavity 210 through a sealing ring.

[0049] In some embodiments, the housing 21 is provided with a movable through hole and a communication hole 213 communicating with the second channel 232. The button 22 includes a pressing part 221 and a moving part 222. The pressing part 221 is fixed above the moving part 222 and extends out of the housing 21 through the movable through hole. The moving part 222 is movably disposed in the travel cavity 210 and fits tightly against the cavity wall of the travel cavity 210 to form a sealed space between the moving part 22 and the travel cavity 210.

[0050] The operation of the liquid filling device is as follows: After the user presses the pressing component 2 multiple times, the gas remaining in the pipeline is first discharged to the outside through the liquid outlet 15; then, the pressing component 2 is pressed again, and the pressure difference generated by the volume change in the stroke chamber 210, combined with the one-way conduction characteristic of the one-way valve, causes the cleaning agent in the first receiving chamber 11 to flow to the pressing component 2 through the second one-way valve 4, and then to the third one-way valve 5, and finally discharged into the clean water tank through the liquid outlet 15. During operation, pressing the pressing part 221 causes the moving part 222 to move downward along the cavity wall of the stroke chamber 210, thereby pushing the gas in the sealed space, and then causing the gas to be discharged to the outside through the third channel 233 of the three-way component 23, forming a pressure difference to drive the liquid in the pipe to move.

[0051] In some embodiments, the housing 21 is provided with a limiting post 214, the button 22 is provided with a receiving groove 223, and the reset member 24 is disposed in the receiving groove 223 and sleeved on the limiting post 214.

[0052] Furthermore, the housing 21 includes a detachably connected upper housing 211 and a lower housing 212. The top of the upper housing 211 is provided with the aforementioned movable through hole, and the bottom of the lower housing 212 is provided with the aforementioned connecting hole 213 and the aforementioned limiting post 214. The lower surface of the moving part 222 is provided with an upwardly recessed receiving groove 223, and the depth of the receiving groove 223 is greater than the extension height of the limiting post 214.

[0053] In a preferred embodiment, the reset member 24 can be a spring, which is disposed in the receiving groove 223 and sleeved on the limiting post 214. When the pressing part 221 is pressed down, the spring is compressed. When the pressure applied to the pressing part 221 is removed, the button 22 is reset under the action of the elastic restoring force of the spring.

[0054] In some embodiments, the housing 1 includes a first housing 13 and a second housing 14, the first housing 13 and the second housing 14 are detachably connected to form a second receiving cavity 12, and the first housing 13 has a first receiving cavity 11 constructed inside it.

[0055] This utility model also provides a floor scrubbing machine, including the above-mentioned liquid dosing device.
