[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0030] Please see Figures 1-6 As shown, this utility model is a liquid filling device for a self-service washing machine and a washing machine, including a fixed box 1. A push-pull assembly 2 is slidably installed inside the fixed box 1. A tension spring 3 is provided between the push-pull assembly 2 and the inner wall of the fixed box 1. A liquid storage chamber 4 is formed between the inner cavity of the fixed box 1 and the push-pull assembly 2. One end of the fixed box 1 is connected to an inlet pipe assembly 5 and an outlet pipe 6. An elastic inlet assembly 7 is provided inside the inlet pipe assembly 5. One end of the elastic inlet assembly 7 is located in the liquid storage chamber 4. An elastic outlet assembly 8 is provided inside the outlet pipe 6. The elastic outlet assembly 8 abuts against one side of the fixed box 1. An electronic flow valve 9 is provided on the outlet pipe 6 on the side away from the elastic outlet assembly 8.

[0031] The device includes a washing machine 10, with the fixing box 1 installed on the washing machine 10, and the liquid outlet pipe 6 connected to the liquid inlet area of ​​the washing machine 10.

[0032] When the user puts clothes into the washing machine 10, the user first pushes the push-pull assembly 2. This is because the push-pull assembly 2 is slidably installed inside the fixed box 1, and a tension spring 3 is provided between it and the inner wall of the fixed box 1. During the pushing process, the push-pull assembly 2 moves into the fixed box 1, making the internal space of the liquid storage chamber 4 smaller. Due to the reduction in the space of the liquid storage chamber 4, the liquid stored in it is squeezed, generating a certain pressure. At this time, the elastic liquid outlet assembly 8 in the inner cavity of the liquid outlet pipe 6, which was originally against one side of the fixed box 1, is pushed open under the pressure of the liquid in the liquid storage chamber 4. The liquid then flows out from the liquid outlet pipe 6 and into the washing area of ​​the washing machine 10, providing the necessary liquid for the washing process, such as detergent or fabric softener. Then, when the user releases the push-pull assembly 2, the tension spring 3 is released. The elastic restoring force of the push-pull component 2 will pull it back to its original position. As the push-pull component 2 resets, the space of the liquid storage chamber 4 will expand again, and a negative pressure will be generated in the liquid storage chamber 4. Under the action of this negative pressure, the elastic liquid inlet component 7 will open. Since one end of the elastic liquid inlet component 7 is located in the liquid storage chamber 4, and the liquid inlet pipe component 5 is connected to the liquid storage tank or an external liquid source, under the influence of the external atmospheric pressure, the external liquid is drawn into the liquid storage chamber 4 through the liquid inlet pipe component 5 to replenish the liquid for the next washing operation. In addition, the liquid outlet pipe 6 is equipped with an electronic flow valve 9, which plays a key role in accurately controlling the liquid flow throughout the process. The controller on the washing machine 10 will calculate the required amount of liquid according to the washing program selected by the user (such as gentle wash, standard wash, heavy wash, etc.) through a certain algorithm.

[0033] For example, in the gentle wash mode, the controller calculates the liquid volume according to the program. If the output liquid is low, the controller sends a control signal to the electronic flow valve 9 based on this calculation result, so that it opens at a small opening for a certain period of time to ensure that the liquid volume flowing out just meets the washing needs. After the liquid volume reaches the required amount, the controller controls the electronic flow valve 9 to close. At this time, one end of the inner cavity of the liquid outlet pipe 6 is blocked and no liquid flows out. At this time, the user will not be able to push the push-pull component 2 to move in the liquid storage chamber 4. At this time, the detergent can be added.

[0034] The entire device is a dynamic, cyclical process. Through the pushing and resetting operation of the push-pull component 2, the liquid in the liquid storage chamber 4 is squeezed out and replenished. At the same time, under the precise control of the controller, the electronic flow valve 9 accurately controls the liquid flow according to different washing conditions, providing efficient, convenient and precise liquid supply and control functions for the washing machine. This not only facilitates user operation but also ensures the accuracy and reliability of liquid addition during the washing process. It avoids problems such as difficulty in controlling the dosage and easy forgetting to bring liquid when adding liquid manually in the traditional way, thus improving the user experience and washing quality of the washing machine.

[0035] In one embodiment, the push-pull assembly 2 includes a push plate 201, which is slidably installed in the inner cavity of the fixed box 1. A moving rod 202 is fixedly installed at one end of the push plate 201, and the moving rod 202 is slidably installed with the fixed box 1. The tension spring 3 is sleeved on the moving rod 202.

[0036] One end of the tension spring 3 is fixedly installed on the push plate 201 and the other end is fixedly installed on the inner wall of the fixed box 1. The moving rod 202 passes through the fixed box 1 and extends to the outside of the fixed box 1. The other end of the moving rod 202 is fixedly installed with a push block 203.

[0037] When the user pushes the push block 203, the push block 203 drives the moving rod 202 to move into the fixed box 1. The moving rod 202 pushes the push plate 201 to slide towards the liquid storage chamber 4 in the inner cavity of the fixed box 1. During this process, the tension spring 3 is compressed, and the space of the liquid storage chamber 4 decreases accordingly. According to the principles of fluid mechanics, the liquid in the liquid storage chamber 4 is squeezed, which will exert pressure on the elastic liquid outlet component 8 in the liquid outlet pipe 6, causing it to open and allowing the liquid to flow out from the liquid outlet pipe 6. When the user releases the push block 203, the elastic potential energy of the tension spring 3 begins to be released, generating a restoring force, pulling the push plate 201 to move away from the liquid storage chamber 4, causing the moving rod 202 and the push block 203 to return to their original positions. At this time, the space of the liquid storage chamber 4 increases, forming a negative pressure. Under the action of the external atmospheric pressure, it will generate a suction force on the elastic liquid inlet component 7 in the liquid inlet pipe assembly 5, causing the elastic liquid inlet component 7 to open, and the liquid will enter the liquid storage chamber 4 through the liquid inlet pipe assembly 5.

[0038] In one embodiment, the liquid inlet pipe assembly 5 includes a connecting pipe 501, which is fixedly installed on the fixing box 1 and communicates with the liquid storage chamber 4. The outer wall of the connecting pipe 501 is fixedly installed on the fixing box 1.

[0039] The other end of the connecting tube 501 is connected to the telescopic tube 502, and the other end of the telescopic tube 502 is connected to the suction tube 503.

[0040] When the user releases the push block 203, the elastic restoring force of the tension spring 3 pulls the push plate 201 back, increasing the volume of the liquid storage chamber 4 and creating a negative pressure inside the liquid storage chamber 4. The connecting pipe 501 is fixedly installed on the fixed box 1 and communicates with the liquid storage chamber 4, serving as a bridge connecting the liquid storage chamber 4 and subsequent pipelines. The telescopic pipe 502 is connected to the other end of the connecting pipe 501. The telescopic pipe 502 has a certain degree of flexibility and can be extended or shortened as needed. When a negative pressure is generated inside the liquid storage chamber 4, it can adjust its length according to the magnitude of the negative pressure and the needs of liquid flow. To ensure smooth liquid flow, the suction pipe 503 is located at the other end of the telescopic pipe 502 and is connected to an external liquid source (such as a storage tank). Due to the negative pressure formed inside the storage chamber 4, the liquid from the external liquid source will be drawn into the suction pipe 503 under the action of external atmospheric pressure. Then, it passes through the telescopic pipe 502 and the connecting pipe 501 and finally enters the storage chamber 4 to realize the liquid filling operation. The telescopic characteristics of the telescopic pipe 502 help to maintain the stability and adaptability of the entire liquid filling process under different installation positions and liquid filling conditions, ensuring that the liquid can be effectively replenished into the storage chamber 4.

[0041] In one embodiment, the elastic liquid inlet assembly 7 includes a support frame 701, which is fixedly installed on the inner wall of the connecting pipe 501. A sliding rod 702 is slidably installed on the support frame 701, and a first spring 703 is sleeved on the outer surface of the sliding rod 702.

[0042] One end of the first spring 703 is fixedly mounted on the support frame 701 and the other end is fixedly mounted on the fixed box 1. One end of the sliding rod 702 is fixedly mounted with a first block 704. The first block 704 is located in the liquid storage chamber 4 and abuts against one side of the fixed box 1.

[0043] The elastic liquid discharge assembly 8 includes a connecting frame 801, which is fixedly installed on the inner wall of the liquid discharge pipe 6, and a connecting rod 802 is slidably installed on the connecting frame 801.

[0044] A second spring 803 is sleeved on the outer surface of the connecting rod 802, and a second block 804 is fixedly installed at one end of the connecting rod 802, with the second block 804 abutting against one side of the fixed box 1.

[0045] The support frame 701 is fixedly installed on the inner wall of the connecting pipe 501, providing a mounting base and support for the sliding rod 702. The sliding rod 702 can slide on the support frame 701. One end of the first spring 703 sleeved on its outer surface is fixed to the support frame 701, and the other end is fixed to the fixing box 1. The first block 704 is fixed to one end of the sliding rod 702 and is located in the liquid storage chamber 4 and abuts against one side of the fixing box 1. Under normal conditions, the first spring 703 is in its natural state or a certain pre-tightened state, causing the first blocking block 704 to tightly block the channel between the connecting pipe 501 and the liquid storage chamber 4, preventing liquid leakage from the liquid storage chamber 4. When the push block 203 is released, a negative pressure is generated in the liquid storage chamber 4, and the external atmospheric pressure is greater than the pressure inside the liquid storage chamber 4. This pressure difference exerts a force on the first blocking block 704, overcoming the elastic force of the first spring 703, pushing the first blocking block 704, causing the sliding rod 702 to slide on the support frame 701, and the first spring 703 to be stretched, thereby opening the channel between the connecting pipe 501 and the liquid storage chamber 4. At this time, external liquid can flow into the liquid storage chamber 4 through the connecting pipe 501, realizing the liquid inlet operation. When the liquid inlet is completed and the pressure difference decreases or disappears, the first spring 703 returns to its original state, pushing the first blocking block 704 to block the channel again, preventing liquid backflow. The connecting frame 801 is fixed on the inner wall of the outlet pipe 6, serving as the mounting support for the connecting rod 802. The connecting rod 802 can slide on the connecting frame 801. A second spring 803 is sleeved on its outer surface. A second blocking block 804 is fixed to one end of the connecting rod 802 and abuts against one side of the fixed box 1. Under normal conditions, the second spring 803 causes the second blocking block 804 to press tightly against the fixed box 1, thereby blocking the channel between the liquid storage chamber 4 and the liquid outlet pipe 6 and preventing liquid from flowing out of the liquid storage chamber 4. When the push block 203 is pushed, the space inside the liquid storage chamber 4 is compressed, and the liquid pressure increases, which will exert pressure on the second blocking block 804, overcoming the elastic force of the second spring 803 and pushing the second blocking block 804, causing the connecting rod 802 to slide on the connecting frame 801. The second spring 803 is compressed, thereby opening the channel between the liquid storage chamber 4 and the liquid outlet pipe 6, allowing the liquid to flow out of the liquid storage chamber 4 and flow to the washing machine 10 through the liquid outlet pipe 6. When the push stops, the liquid pressure decreases, the second spring 803 returns to its original state, and pushes the second blocking block 804 to block the channel again, preventing the liquid from continuing to flow out.
