[0035] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0036] The present invention provides an automatic ejection device, such as Figure 1-6 As shown, the push-up device body 100 includes a driving assembly, a fixed box body 20, and a mobile box body 10. The fixed box body 20 is connected with the mobile box body 10 in an inlay connection. The mobile box body 10 is embedded in the fixed box body 20. The fixed box body 20 includes at least one inlet 210. Under the action of the driving assembly, the driving medium enters the fixed box body 20 from the inlet 210. The force of the driving medium on the mobile box body 10 causes the push-up device body 100 to be automatically pushed. In one embodiment, the mobile box body 10 is embedded in the interior of the fixed box body 20. The mobile box body 10 moves inside the fixed box body 20 under the action of the driving force generated by the driving assembly; the driving assembly drives the driving medium to enter the fixed box body through the inlet 210 and act on the mobile box body 10, so that the mobile box body 10 moves. The washing machine is an electrical appliance that needs to use water or gas. The driving force originally existing in the washing machine itself is used to simplify the device and save costs. For example, the driving assembly drives water to move the mobile box 10 through hydraulic pressure or drives the mobile box 10 to move through air pressure. In addition, the number of inlets 210 can be set to multiple, and multiple inlets 210 can shorten the time for the driving assembly to generate driving force and improve driving efficiency.

[0037] In one embodiment, the mobile box body 10 moves inside the fixed box body 20, and the fixed box body 20 and the mobile box body 10 form a closed space; in the initial state, the mobile box body 10 is close to the washing machine housing, and under the action of the driving force generated by the driving assembly, the mobile box body 10 moves and moves away from the washing machine housing. The main body of the push-up device is embedded in the washing machine housing, the fixed box body 20 is fixed on the washing machine housing, and the mobile box body 10 moves relative to the washing machine housing. The mobile box body 10 and the fixed box body 20 form a closed space, which includes an inlet 210. By inputting a driving medium into the inlet 210, the pressure in the closed space is increased, thereby driving the mobile box body 10 to move in a direction away from the washing machine housing. The continuous input of driving force causes the mobile box body 10 to move continuously, and the speed of the movement of the mobile box body 10 is related to the capacity and speed of the driving assembly inputting the driving force into the closed space.

[0038] Preferably, the entrance 210 is arranged on a side of the fixed box body close to the washing machine housing. In the initial state, the movable box body is close to the entrance 210. When the driving force generated by the driving component acts, the movable box body 10 moves away from the entrance 210.

[0039] In a specific embodiment, the driving assembly includes a water inlet valve of the washing machine, which is connected to the inlet port 210. The driving assembly injects water into the enclosed space through the inlet port 210. The pressure generated by the water in the enclosed space causes the movable box body 10 to move out of the fixed box body 20.

[0040] In another embodiment, the driving assembly includes an air intake valve of the washing machine, which is connected to the inlet port 210. The driving assembly injects gas into the enclosed space through the inlet port 210. The pressure generated by the gas in the enclosed space causes the movable box body 10 to move out of the fixed box body 20.

[0041] The air pump or water pump of the washing machine itself drives the assembly to be connected to the air inlet valve or water inlet valve of the washing machine. When the detergent box needs to be opened, gas or liquid is injected into the enclosed space through the inlet to increase the pressure in the enclosed space to drive the mobile box body 10 to move relative to the fixed box body 20. For example, when the user needs to wash clothes and finds that the detergent in the detergent box is insufficient and needs to be added, the detergent box needs to be opened, that is, the mobile box body 10 is opened. By connecting the inlet 210 with the water inlet valve of the washing machine, water is continuously injected into the enclosed space, and the water pressure in the enclosed space increases to drive the mobile box body 10 to move, that is, the detergent box is opened outwards. After the detergent box is opened, the user adds detergent to the inside.

[0042] The fixed box body 20 includes at least one discharge port 220, and the discharge port 220 is used to discharge the driving medium in the fixed box body 20. Preferably, the discharge port 220 is arranged at the bottom of the fixed box body 20. The discharge port 220 is connected to the inner drum or outer drum of the washing machine. After the mobile box body 10 moves out of the fixed box body 20 under the action of the driving force. The driving medium, i.e., liquid or gas, is discharged from the fixed box body 20 through the discharge port 220. When the driving medium is liquid, the discharge port 220 is connected to the inner drum of the washing machine; when the driving medium is gas, the discharge port 220 is connected to the outer drum of the washing machine.

[0043] The discharge port 220 is disposed at one end of the mobile box body 10 away from the inlet port 210. When the mobile box body 10 moves to the discharge port 220, the driving medium in the fixed box body 20 is discharged from the discharge port 220. When the mobile box body 10 moves by the pressure formed by the liquid or gas in the above embodiment in the closed space, when the discharge port 220 enters the closed space during the movement of the mobile box body 10, the closed space will no longer be closed, and the liquid or gas will no longer generate pressure in the space, and the mobile box body 10 will stop moving; in this embodiment, the discharge port 220 also serves as a switch to stop the movement of the mobile box body 10.

[0044] In another embodiment, Figure 3As shown, the driving assembly includes a booster pump (not shown in the figure), one end of the booster pump is connected to the water inlet valve of the washing machine and the other end is connected to the inlet port 210; the water input from the inlet valve forms a water column 40 under the action of the booster pump, and the impact force generated by the water column 40 on the mobile box body 10 causes it to move out of the fixed box body 20. The difference between this embodiment and the previous embodiment is that the driving medium in this embodiment does not need to be in a closed space, and the booster pump causes the water entering from the inlet port 210 to form a water column 40, and the impact force generated by the water column acts on the mobile box body 10. In this embodiment, the discharge port 220 is set at one end of the mobile box body 10 close to the inlet port 210, and when the water column 40 acts on the mobile box body 10, it is discharged from the fixed box body 20 through the discharge port 220. The discharge port 220 in this embodiment has the same function as the discharge port 220 in the previous embodiment, and is used to discharge the driving medium liquid or gas. The difference is that the discharge port 220 in the previous embodiment serves to stop the moving box body 10, while the discharge port 220 in this embodiment is used to discharge the driving medium and water in time to prevent the driving medium from being retained in the fixed box body 20 and affecting the formation of the water column. It should be noted that the discharge port 220 in this embodiment is arranged near the inlet 210, so that the liquid falling in the fixed box body 20 can be discharged from the discharge port 220 when the water column 40 is just formed.

[0045] In a preferred embodiment, Figure 6 As shown, the ejection device body 100 further includes a stopper, which is used to limit the position of the movable box body 10. When the movable box body 10 moves so that the discharge port 220 enters the enclosed space, the water in the enclosed space is discharged and the movable box body 10 stops moving. However, due to inertia, the movable box body 10 will continue to decelerate until the speed reaches zero. In order to prevent the movable box body 10 from detaching from the fixed box body 20, the stopper is used to prevent the movable box body 10 from detaching from the fixed box body 20.

[0046] Specifically, the mobile box body 10 is a box body with an opening at the top for storing materials, and the limiting member is a limiting block 310. The limiting block 310 is fixedly installed on the inner wall at the top of the fixed box body 20, and the limiting block 310 is located in the space formed by the box body to prevent the mobile box body 10 from leaving the fixed box body 20. The mobile box body 10 is used to store detergent, and the upper end of the detergent box is open and similar to a drawer. The limiting block 310 is fixedly installed on the inner wall at the top of the fixed box body 20 and is located in the space of the mobile box body 10. During the movement of the mobile box body 10, after the discharge port 220 enters the enclosed space, the mobile box body 10 continues to move. At this time, the limiting block 310 will prevent it from continuing to move. The limiting block 310 protrudes from the inner wall of the fixed box body 20 to block the side wall of the mobile box body 10, and the side wall moves in the enclosed space. In addition, an elastic pad is installed on the limit block 310 , and when the moving box body 10 moves too fast, the elastic pad is used to buffer the contact of the moving box body 10 with the limit block 310 .

[0047] In one embodiment, a sealing strip is installed at the end of the movable box body 10, and the sealing strip is preferably a rubber strip, and the outer diameter of the sealing strip matches the inner diameter of the fixed box body 20, and the sealing strip is used to form a closed space between the movable box body 10 and the fixed box body 20. The sealing strip in this embodiment is similar to the rubber plug at the end of the push rod of a needle hole syringe, and the push rod forms a closed space between the end of the syringe and the push rod through the rubber plug during the movement of the push rod for storing liquid medicine.

[0048] In one embodiment, Figure 4 , Figure 5 As shown, a guide structure is provided between the fixed box body 20 and the mobile box body 10, and the guide structure is used to move the mobile box body 10 in one direction. Specifically, a plurality of slide grooves 230 are provided on the inner wall of the fixed box body 20, and a slider 110 matching the slide grooves 230 is provided on the outer wall of the mobile box body 10, so that the mobile box body 10 moves along the direction of the slide grooves 230 during the movement. In this embodiment, the fixed box body 20 and the mobile box body 10 are rectangular parallelepiped structures, and the mobile box body 10 is easy to deviate during the movement of the mobile box body 10 inside the fixed box body 20, causing the mobile box body 10 to be stuck in the fixed box body 20 and unable to move. The slide grooves 230 provided on the inner wall of the fixed box body 20 are guiding, so that the slider 110 on the mobile box body 10 moves along the slide grooves 230 to avoid deviation during the movement.

[0049] The invention also provides a washing machine, comprising an automatic push-open device.

[0050] The present invention discloses an automatic ejection device, wherein a fixed box body of the ejection device body is engaged with a movable box body, and a driving medium enters the fixed box body under the action of a driving component of the washing machine itself, and the driving medium generates a thrust on the movable box body to realize automatic ejection of the movable box body;

[0051] The tap water or gas generated by the air pump or water pump of the washing machine itself is input into the closed space through the inlet. The pressure of the tap water or gas in the closed space causes the movable box body to pop out of the fixed box body. The push-to-pop structure is simple, saves cost and has stable performance.

[0052] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention.
