DETAILED DESCRIPTION

[0029] The present invention will be further described below in conjunction with the accompanying drawings. It should be noted that this embodiment is based on the technical solution and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to this embodiment.

[0030] Example 1

[0031] like Figure 1 As shown, the material box includes a dispenser box 6 and a detergent box 7. The dispenser box 6 is located on the upper part of the detergent box 7, and the dispenser box 6 can be moved between an open position and a closed position.

[0032] The material box pop-up damping structure includes a accommodating cavity 1, in which a sealing element 2 is arranged, and the accommodating cavity 1 is divided into a first cavity and a second cavity; the first cavity is connected to the delivery port of the dispenser box, and air can enter the first cavity through the delivery port of the dispenser box, and the second cavity is an air pressure cavity. A push rod 5 is arranged at the rear end of the dispenser box 6, and the push rod 5 is connected to the dispenser box 6. The push rod 5 extends into the first cavity and moves axially in the first cavity. The front and rear axial movement of the push rod 5 in the first cavity can also play a limiting role of the dispenser box, ensuring that the movement direction of the dispenser box is front and rear movement, so that the dispenser box will not fluctuate up and down. An elastic member 4 is arranged in the second cavity, and the elastic member 4 is used to provide the ejection force of the dispenser box 6. A first through hole 11 is arranged on the sealing element 2, and a groove 12 is arranged on the end of the sealing element 2 that contacts the first cavity, and the groove 12 is connected to the first through hole 11. In another embodiment, the groove 12 may also not be arranged, and the present invention is not limited to this. A plug 3 is disposed at the rear end of the second cavity, and a second through hole 9 is disposed on the plug 3. The second through hole 9 connects the second cavity and the atmosphere.

[0033] When the dispenser box 6 is closed, the push rod 5 and the sealing element 2 slide together to the rear end of the first cavity. When the dispenser box 6 is opened, the push rod 5 slides to the front end of the first cavity. In the present invention, the elastic member 4 is preferably a spring, and the sealing element 2 is preferably a sealing ring. A push switch (not shown in the figure) is provided at the front end of the dispenser box for opening and closing the dispenser box 6. The push switch is also provided with a locking device for use therewith (not shown in the figure, the locking device is a prior art, and this embodiment is not described in detail). When the user pushes the push switch, the locking device opens, and the elastic force of the elastic member in the second cavity causes the dispenser box 6 to move from back to front, exposing the dispenser box for the convenience of the user to put in detergent. During the movement of the dispenser box 6, the push rod moves from back to front, and the sealing element 2 moves with the push rod 5, such as Figure 2As shown by the arrow, air enters the second cavity from the second through hole, and enters the second cavity from the first through hole through the first cavity. The diameter of the first through hole and the second through hole is less than 5 mm. Since the first through hole and the second through hole are very small, the air entering the second cavity in a short time is limited, and the air volume of the second cavity increases rapidly. The air pressure in the second cavity is less than the atmospheric pressure. The atmospheric pressure at the dispenser box acts on the push rod, reducing the elastic force of the elastic member, thereby providing a damping force for the ejection of the material box, reducing the ejection speed of the material box, and improving the service life of the material box.

[0034] When the user puts in the detergent, the air slowly enters the second cavity from the first through hole and the second through hole, and the air pressure in the second cavity is the same as the atmospheric pressure. When the user has finished putting in the detergent, he pushes the press switch again, the locking device is locked, and the dispenser box is closed. When the dispenser box 6 moves from front to back, the elastic member is compressed, generating an elastic force from back to front, and at the same time, the volume of the air in the second cavity decreases and the pressure increases. The force applied by the user is greater than the elastic force of the elastic member and the difference between the air pressure in the second cavity and the atmospheric pressure. At the same time, the air is continuously discharged from the second cavity, so that the air pressure in the second cavity decreases, so that the dispenser box can be pushed in smoothly.

[0035] The beneficial effect of this embodiment is that the damping component of the material box pop-up structure has a simple structure and low cost, which can reduce the cost of the washing machine.

[0036] Example 2

[0037] like Figure 3 As shown, in this embodiment, based on the embodiment 1, a one-way valve 10 is arranged in front of the groove of the sealing element 2. In another embodiment, the one-way valve 10 can also be arranged on the same side of the first through hole, and the present invention is not limited to this. When the one-line valve 10 is opened, the one-way valve and the first through hole 11 communicate with the first cavity and the second cavity.

[0038] The elastic member 4 of the present invention is preferably a spring, and the sealing element 2 is a sealing ring. A push switch (not shown in the figure) is provided at the front end of the dispenser box for opening and closing the dispenser box 6. The push switch is also provided with a locking device (not shown in the figure, the locking device is a prior art, and this embodiment is not described in detail). When the user pushes the push switch, the locking device opens, and the one-way valve closes the groove of the sealing element. The elastic force of the elastic member in the second cavity causes the dispenser box 6 to move from the back to the front, exposing the dispenser box, so that the user can put in detergent. During the movement of the dispenser box 6, air enters the second cavity through the second through hole 9. At this time, the one-way valve is in a closed state, and air only enters the second cavity from the second through hole, and the air in the first cavity does not enter the second cavity. Compared with Example 1, less air enters the second cavity in a short time, while the air volume of the second cavity increases rapidly, and the air pressure in the second cavity is less than the atmospheric pressure. The atmospheric pressure at the dispenser box acts on the push rod, reducing the elastic force of the elastic member, thereby providing a damping force for the ejection of the dispenser box, reducing the ejection speed of the dispenser box, and increasing the service life of the dispenser box. In this embodiment, the air pressure in the second cavity is smaller, and the damping force for the ejection of the dispenser box is greater, which can better buffer the ejection speed of the dispenser box.

[0039] When the user puts in the detergent, air slowly enters the second cavity from the second through hole, and the air pressure of the second cavity is the same as the atmospheric pressure. When the user has finished putting in the detergent, he pushes the press switch again, the locking device is locked, and the dispenser box is closed. When the dispenser box 6 moves from front to back, the elastic member is compressed, generating an elastic force from back to front. At the same time, the one-way valve on the sealing element 2 opens, the volume of the air in the second cavity decreases, and the pressure increases. The air is discharged into the first cavity through the one-way valve 10 and the first through hole 11 and enters the atmosphere. At the same time, the air in the second cavity is also discharged through the second through hole 9. Since the first through hole and the second through hole are very small in size, the air discharged from the second cavity in a short time is limited, and the air pressure in the second cavity is greater than the atmospheric pressure. The force applied by the user pushes the push rod to slide. Compared with Example 1, the air in the second cavity can also be discharged to the atmosphere through the first through hole, and can be discharged faster. The air pressure in the second cavity quickly becomes consistent with the atmospheric pressure. The thrust applied by the user changes from being greater than the sum of the thrust of the elastic member and the difference between the air pressure in the second cavity and the atmospheric pressure to being greater than the thrust of the elastic member, making the pushing of the material box smoother. The beneficial effect of this embodiment is that the one-way valve is set, which can make the push of the dispenser box smoother when the dispenser box is closed.

[0040] Example 3

[0041] A material box includes a dispenser box 6 and a detergent box 7. The dispenser box 6 is located on the upper part of the detergent box 7 and can be moved between an open position and a closed position. The dispenser box is located on the upper part of the detergent box and can be moved between an open position and a closed position. The material box uses the material box pop-up damping structure described in Examples 1 and 2. The material box pop-up damping structure is connected to the dispenser box.

[0042] Example 4

[0043] The present invention provides a washing machine, including a drum washing machine or a pulsator washing machine. The washing machine uses the material box pop-up damping structure described in Example 1 or Example 2 and the material box described in Example 3, and the material box is installed outside the water channel structure of the washing machine.

[0044] like Figure 1 As shown, in the prior art, a washing machine that uses a manually pulled-out detergent box is provided with two water inlet valves to control three water channels. One end of the first water inlet valve extends out of the washing machine, and the other end is connected to the first water channel inside the washing machine. The first water inlet valve is set to intersect with the horizontal line of the washing machine at an angle of about 135 degrees. The setting angle of the first water channel is the same as that of the first water inlet valve, and is on the same line as the first water inlet valve. After water enters from the inlet of the first water inlet valve, it enters the first water channel along a straight line. One end of the second water inlet valve extends out of the washing machine, and the other end is connected to the second water channel inside the washing machine. The second water inlet valve is set to intersect with the horizontal line of the washing machine at an angle of about 45 degrees. The setting angle of the second water channel is the same as that of the second water inlet valve, and is on the same line as the second water inlet valve. After water enters from the inlet of the second water inlet valve, it enters the second water channel along a straight line. The first water inlet valve and the second water inlet valve are arranged opposite to each other, and the outlets of the first water inlet valve and the second water inlet valve intersect. The third water channel is arranged between the first water channel and the second water channel, and is arranged vertically. After the water from the first water inlet valve and the second water inlet valve collide at the outlet, part of the water flows into the third waterway, so the two water inlet valves can control three waterways. The hand-pull material box is arranged on one side of the first water inlet valve and the second water inlet valve, with one end extending out of the washing machine and the other end extending into the washing machine. The end extending into the washing machine does not intersect with the first waterway, the second waterway and the third waterway, and will not affect the two water inlet valves controlling the three waterways.

[0045] like Figure 2As shown, in the prior art, a washing machine using a pop-up damping material box is provided with a first water inlet valve, a second water inlet valve and a third water inlet valve, and the first water inlet valve, the second water inlet valve and the third water inlet valve are arranged perpendicular to the horizontal line of the washing machine. One end of the first water inlet valve extends out of the washing machine, and the other end extends into the first waterway inside the washing machine. One end of the second water inlet valve extends out of the washing machine, and the other end extends into the second waterway inside the washing machine. One end of the third water inlet valve extends out of the washing machine, and the other end extends into the third waterway inside the washing machine. The traditional material box damping device is arranged perpendicular to the horizontal line of the washing machine, parallel to the second water inlet valve and the third water inlet valve, and between the second water inlet valve and the third water inlet valve. One end of the material box damping device extends out of the washing machine, and the other end extends into the washing machine, and the main structure of the material box damping device is between the second waterway and the third waterway. Because the middle position of the washing machine waterway structure is occupied by the pop-up damping material box, after the water reaches the outlet of the second water inlet valve and the third water inlet valve, it cannot collide and enter another waterway, and a first water inlet valve needs to be set separately to control the three waterways.

[0046] The material box provided by the present invention is arranged outside the water channel structure of the washing machine. Since the middle position of the water channel structure of the washing machine is not occupied by the material box, only two water inlet valves, the first water inlet valve 13 and the second water inlet valve 14, are needed to control the three water channels. Figure 6 As shown, one end of the first water inlet valve 13 extends out of the washing machine, and the other end is connected to the first waterway inside the washing machine. The first water inlet valve is set to intersect with the horizontal line of the washing machine at an angle of about 135 degrees. The setting angle of the first waterway is the same as that of the first water inlet valve, and it is on the same line with the first water inlet valve. After water enters from the inlet of the first water inlet valve, it enters the first waterway along a straight line. One end of the second water inlet valve 14 extends out of the washing machine, and the other end is connected to the second waterway inside the washing machine. The second water inlet valve is set to intersect with the horizontal line of the washing machine at an angle of about 45 degrees. The setting angle of the second waterway is the same as that of the second water inlet valve, and it is on the same line with the second water inlet valve. After water enters from the inlet of the second water inlet valve, it enters the second waterway along a straight line. The first water inlet valve and the second water inlet valve are arranged oppositely, and the outlets of the first water inlet valve and the second water inlet valve intersect. The third waterway is arranged between the first waterway and the second waterway, and is arranged vertically. After the water of the first water inlet valve and the second water inlet valve collide at the outlet, part of the water flows into the third waterway, so the two water inlet valves can control three waterways.

[0047] The material box is arranged between the first water inlet valve and the second water inlet valve. The first water inlet valve intersects with the horizontal line of the washing machine at an angle of about 135 degrees, the second water inlet valve intersects with the horizontal line of the washing machine at an angle of about 45 degrees, and the material box is arranged perpendicular to the horizontal line of the washing machine. The end of the material box connected to the washing machine is in contact with one end of the first water inlet valve connected to the washing machine and one end of the second water inlet valve connected to the washing machine. Since the material box does not enter the first waterway, the second waterway and the third waterway, the water collides after reaching the outlets of the first water inlet valve and the second water inlet valve, and part of the water can enter the third waterway, which will not affect the two water inlet valves controlling the 3-way waterway. Therefore, the material box used in the washing machine in this embodiment not only reduces the cost of the material box, but also reduces the number of water inlet valves, further reducing the cost of the washing machine.
