[0054] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "contacted", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0055] When the washing machine is running at high speed, vibration is inevitable. The detergent dispenser box is prone to poor sealing when subjected to vibration, causing the laundry detergent to seep into the clothing processing drum or other connecting parts, resulting in incomplete rinsing or damage to other connecting parts.

[0056] Based on this, the following embodiments are proposed.

[0057] Embodiment 1:

[0058] like Figure 1-4 As shown in , 7, this embodiment provides a sealing member, including:

[0059] A sealing body 1, on which a first sealing mating surface 101 and a second sealing mating surface 102 are formed;

[0060] Preferably, the sealing body 1 is annular, and an annular first sealing mating surface 101 is formed on the inner ring side of the sealing body, and an annular second sealing mating surface 102 is formed on the outer ring side. The first sealing mating surface and the second sealing mating surface 102 are used for sealing with different sealing objects;

[0061] The sealing body 1 forms an annular groove 2 between the first sealing mating surface 101 and the second sealing mating surface 102, and the opening of the annular groove faces one axial side of the sealing body 1;

[0062] The sealing body 1 is an elastic body. When the second sealing mating surface 102 and / or the first sealing mating surface 101 is subjected to external force, the volume of the groove cavity of the annular groove 2 changes.

[0063] Preferably, the sealing body 1 forms a first axial end face and a second axial end face on opposite axial sides of the first sealing mating surface 101 and the second sealing mating surface 102; the guide slope extends from one side of the first axial end face to one side of the second axial end face, the outer circle radius of the first axial end face is greater than the outer circle radius of the second axial end face, and the opening of the annular groove is opened on one side of the first axial end face. When the second sealing mating surface 102 and / or the first sealing mating surface 101 are subjected to external force, the groove cavity volume of the annular groove 2 changes.

[0064] In the present embodiment, preferably, the sealing body 1 is made of elastic rubber material as a whole, and is assembled on the connecting pipe between the water inlet box and the detergent delivery box of the washing machine. This can provide good sealing and shock-absorbing effects on the detergent delivery box when it works in a vibrating working environment of the washing machine, thereby preventing the laundry detergent from seeping into the clothing processing drum or other connecting parts, causing incomplete rinsing or damaging other connecting parts.

[0065] Specifically, the advantages of the sealing member are explained by taking the connecting pipe including the first connecting pipe 801 and the second connecting pipe 802 as an example. The first sealing mating surface 101 is connected to the outer wall of the first connecting pipe 801. When the first connecting pipe 801 and the second connecting pipe 802 are connected, the inner wall of the second connecting pipe 802 is close to the second sealing mating surface 102. When the washing machine is running at high speed, it is accompanied by vibration. When the detergent dispenser is vibrated, the first connecting pipe 801 and the second connecting pipe 802 are vibrated. In this state, since an annular groove 2 is formed between the first sealing mating surface 101 and the second sealing mating surface 102, the first sealing mating surface 101 is provided with a plurality of sealing mating surfaces. 01 and the second sealing mating surface 102 are subjected to an indeterminate force due to the vibration of the two tubes, the annular groove 2 is squeezed and the volume of the groove cavity changes. The change in the volume of the groove cavity can consume the external force, thereby playing a role in buffering the vibration between the two tubes. At the same time, the second sealing mating surface 102 and the second connecting tube 802 are close together with a certain amount of margin, and the effective seal between the second connecting tube 802 and the first connecting tube 801 can be maintained even in a vibrating state, thereby effectively solving the problem of contact end leakage when the washing machine is stationary or running at high speed, and can prevent the detergent dispenser box from loosening and leaking due to vibration, and can also solve the problem of poor sealing of the detergent dispenser box.

[0066] Optionally, in an implementation of this embodiment, as Figure 1-4 As shown,

[0067] The second sealing mating surface 102 forms a guide slope inclined relative to the axial center line of the sealing body 1;

[0068] The sealing body 1 is a sealing ring, the first sealing mating surface 101 is formed on the inner ring (i.e. the inner wall) of the sealing body 1, and the second sealing mating surface 102 is formed on the outer ring (i.e. the outer wall) of the sealing body 1. The second sealing mating surface 102 is inclined relative to the first sealing mating surface 101, i.e. forming a guide slope.

[0069] In this embodiment, the sealing ring is more suitable for sealing connecting pipes with different diameters at two connection points. The advantages of the sealing member are illustrated by taking the connecting pipe including the first connecting pipe 801 and the second connecting pipe 802 as an example. The first sealing mating surface 101 is connected to the outer wall of the first connecting pipe 801. When the first connecting pipe 801 and the second connecting pipe 802 are in the connected state, the inner wall of the second connecting pipe 802 is in close contact with the second sealing mating surface 102. The second sealing mating surface 102 is inclined to form a guide slope structure. The guide slope structure can guide the detergent dispensing box when it is pushed into the water inlet box, and the pushing process is smoother and easier. At the same time, the guide slope structure can make the friction surface relatively small when the detergent dispensing box is pulled out of the water inlet box, and the pulling process is more labor-saving, thereby realizing that the detergent dispensing box can be easily pulled out of the water inlet box.

[0070] Optionally, in an implementation of this embodiment, as Figure 1-4 As shown,

[0071] The first sealing mating surface 101 is a cylindrical surface, and the second sealing mating surface 102 is inclined relative to the first sealing mating surface 101 and is a sloped surface.

[0072] In this embodiment, the sealing body 1 is annular, wherein the cylindrical surface is more adapted to the circular tube structure, and the second sealing mating surface 102 is inclined relative to the first sealing mating surface 101, and is a sloped surface. The sloped surface can guide the detergent dispensing box when it is pushed into the water inlet box, and the pushing process is smoother and easier. At the same time, the sloped surface can make the friction surface relatively small when the detergent dispensing box is pulled out of the water inlet box, and the pulling out process is more labor-saving, thereby realizing that the detergent dispensing box can be easily pulled out of the water inlet box.

[0073] Optionally, in an implementation of this embodiment, as Figure 1-4 As shown,

[0074] The opening width of the annular groove 2 gradually decreases from the groove opening to the groove bottom.

[0075] The opening width of the annular groove 2 gradually decreases from the groove opening to the groove bottom. The radial cross-section of the groove cavity of the annular groove 2 is wedge-shaped. When the first sealing mating surface 101 and the second sealing mating surface 102 are subjected to an indefinite direction of force due to the vibration of the two tubes, the annular groove 2 is squeezed, and the end of the wedge-shaped groove cavity close to the groove opening directly contacts the second connecting tube 802, and the volume is easier to change, thereby consuming external force more effectively, and effectively buffering the vibration between the two tubes. At the same time, the groove cavity cross-section of the annular groove 2 is wedge-shaped, so that the second sealing mating surface 102 and the second connecting tube 802 are close to each other with a certain abutment margin, and the effective seal between the second connecting tube 802 and the first connecting tube 801 can be maintained in the vibrating state, thereby effectively solving the contact end leakage problem of the washing machine when it is stationary or running at high speed, and can prevent the detergent delivery box from loosening and leaking due to vibration, and can also solve the problem of poor sealing of the detergent delivery box.

[0076] Optionally, in an implementation of this embodiment, as Figure 1-4 As shown,

[0077] The sealing body 1 forms a first axial end face 103 and a second axial end face 104 on opposite axial sides of the first sealing mating surface 101 and the second sealing mating surface 102; the guide slope extends from one side of the first axial end face 103 to the second axial end face 104, the outer circle radius of the first axial end face 103 is greater than the outer circle radius of the second axial end face 104, and the opening of the annular groove 2 is opened on one side of the first axial end face 103.

[0078] In this embodiment, the sealing body 1 has a first axial end face 103 and a second axial end face 104 formed relatively on the axial sides of the first sealing mating surface 101 and the second sealing mating surface 102, so that the sealing body 1 has a larger connection surface with the connecting groove to which it is connected. The connecting groove can be a groove opened on the wall of the tube body to be sealed, thereby making the connection between the sealing body 1 and the connecting groove more firmly.

[0079] Embodiment 2

[0080] like Figure 2-7 As shown, a delivery component is provided, including

[0081] The sealing member in the first embodiment;

[0082] A first connection box 3, a second connection box 4 and a dosing pump 6, wherein the second connection box 4 is detachably connected to the first connection box 3 and is used to store detergent, a liquid extraction end of the dosing pump 6 is connected to the second connection box 4 and is used to extract detergent from the second connection box 4, and a water outlet pipe 7 is provided at the lower end of the first connection box 3;

[0083] The liquid inlet of the dosing pump 6 is connected to the second connection box 4, and the liquid outlet is connected to the water outlet pipe 7, so as to draw detergent from the second connection box 4 and send it to the water outlet pipe 7;

[0084] The sealing member is disposed between the first connection box 3 and the second connection box 4 .

[0085] In this embodiment, Figure 2 The figure shows a schematic diagram of the overall structure of the dispensing component, wherein the first connecting box 3 is a water inlet box, and the second connecting box 4 is a detergent dispensing box. The second connecting box 4 is connected to an external faucet for water intake, and the water intake can also wash away other substances involved in washing such as softener added to the second connecting box 4 except detergent. The second connecting box 4 is in the shape of a drawer, which can be pulled out and moved in the first connecting box 3, and the second connecting box 4 is used to store detergent.

[0086] like Figure 3 , 4 As shown, it is a schematic diagram of the structure of the delivery component in the working state. In the working state, the second connection box 4 is pushed into the first connection box 3 and locked, and the two boxes are connected. When the clothes need to be washed, the delivery pump 6 can extract the laundry liquid from the second connection box 4, such as Figure 5 , 6 The diagram shows the structure of the second connection box 4 and the first connection box 3 in a separated state, which refers to a state in which the user partially pulls the second connection box 4 out of the first connection box 3. At this time, the dosing pump 6 cannot normally extract detergent from the second connection box 4.

[0087] The sealing member is arranged between the first connecting box 3 and the second connecting box 4, that is, the first sealing mating surface 101 is connected to the outer wall of the first connecting tube 801, and when the first connecting tube 801 and the second connecting tube 802 are in the connected state, the inner wall of the second connecting tube 802 is in close contact with the second sealing mating surface 102, wherein the first connecting tube 801 is located in the first connecting box 3, and the second connecting tube 802 is located in the second connecting box 4. The advantages of the sealing member in Example 1 are reflected in the delivery component and will not be repeated here.

[0088] Optionally, in an implementation of this embodiment, as Figure 4 , 6 , 7,

[0089] A valve tube 8 is provided between the first connection box 3 and the second connection box 4. The valve tube 8 includes a first connecting tube 801 and a second connecting tube 802 connected to each other. The first connecting tube 801 is located in the first connection box 3 and is connected to the liquid extraction end of the delivery pump 6. The second connecting tube 802 is located in the second connection box 4 and is connected to the box cavity of the second connection box 4. A valve body 803 is provided in the second connecting tube 802.

[0090] The first sealing mating surface 101 of the sealing body 1 is connected to the outer side wall of the first connecting pipe 801;

[0091] When the first connecting tube 801 and the second connecting tube 802 are in a connected state, the inner wall of the second connecting tube 802 is in close contact with the second sealing mating surface 102 of the sealing body 1, and the valve body 803 connects the first connecting tube 801 and the second connecting tube 802. When the first connecting tube 801 and the second connecting tube 802 are in a separated state, the inner wall of the second connecting tube 802 is separated from the second sealing mating surface 102 of the sealing body 1, and the valve body 803 closes the second connecting tube 802.

[0092] In this embodiment, Figure 4 As shown, it is a schematic diagram of the structure of the dispensing component in the working state. In the working state, the second connecting box 4 is pushed into the first connecting box 3 and locked, and the two boxes are connected. At this time, the first connecting pipe 801 and the second connecting pipe 802 are in a connected and connected state. When it is necessary to wash clothes, the dispensing pump 6 can extract laundry detergent from the second connecting box 4. Under the action of the pump force, the detergent is collected by the second connecting pipe 802, the first connecting pipe 801 and other flow paths to the water outlet pipe 7, and is discharged from the water outlet pipe 7 to the clothes processing barrel of the washing machine to participate in washing. In this state, the inner side wall of the second connecting pipe 802 is in close contact with the second sealing matching surface 102 of the sealing body 1, and the valve body 803 connects the first connecting pipe 801 and the second connecting pipe 802. During the high-speed operation of the washing machine, there is vibration. When the detergent dispensing box is vibrated, the first connecting pipe 801 and the second connecting pipe 802 are connected. The connecting tube 802 vibrates accordingly. In this state, since an annular groove 2 is formed between the first sealing mating surface 101 and the second sealing mating surface 102, when the first sealing mating surface 101 and the second sealing mating surface 102 are subjected to an indefinite direction of force due to the vibration of the two tubes, the annular groove 2 is squeezed and its groove cavity volume changes. The change in the groove cavity volume can consume external force, thereby playing a role in buffering the vibration between the two tubes. At the same time, the second sealing mating surface 102 and the second connecting tube 802 are close together with a certain close-fitting margin, and the effective seal between the second connecting tube 802 and the first connecting tube 801 can be maintained even in the vibrating state, thereby effectively solving the problem of contact end leakage when the washing machine is stationary or running at high speed, and can prevent the detergent dispenser box from loosening and leaking due to vibration, and can also solve the problem of poor sealing of the detergent dispenser box.

[0093] like Figure 6The figure shows a schematic diagram of the structure of the second connecting box 4 and the first connecting box 3 in the separated state. The separated state refers to the state in which the user partially pulls the second connecting box 4 out of the first connecting box 3. At this time, the first connecting tube 801 and the second connecting tube 802 are in a separated state, and the valve body 803 closes the second connecting tube 802. At this time, the delivery pump 6 cannot normally extract detergent from the second connecting box 4 while also ensuring that the detergent will not leak during the filling process.

[0094] Optionally, in an implementation of this embodiment, as Figure 4 , 6 , 7,

[0095] The number of the sealing bodies 1 provided is at least 2.

[0096] Preferably, the number of sealing bodies 1 is 2.

[0097] The double sealing body is set up for redundancy, and if one of them fails, the other can still play a sealing role.

[0098] Optionally, in an implementation of this embodiment, as Figure 4 , 6 As shown,

[0099] A flow channel 9 connected to the valve tube 8 is arranged in the first connection box 3. The flow channel 9 has a spray port at the upper end and a connection port at the lower end. The spray port is connected to the output end of the external sprayer, and the connection port is connected to the first connecting pipe.

[0100] In this embodiment, the sprayer sprays water to the spray port, so that the spray water enters the flow channel 9 and mixes with the detergent flowing from the valve tube 8, thereby increasing the flow speed of the detergent and reducing the detergent sticking to the wall. The mixed liquid is discharged from the outlet pipe 7 to the clothes processing drum of the washing machine to participate in washing.

[0101] Optionally, in an implementation of this embodiment, as Figure 4 , 6 As shown,

[0103] A seal is provided between the first flow channel section 901 and the second flow channel section 902 . The first sealing mating surface 101 of the sealing body 1 is connected to the outer wall of the first flow channel section 901 , and the second sealing mating surface 102 of the sealing body 1 is abutted against the inner wall of the second flow channel section 902 .

[0104] The upper end of the first flow channel section 901, i.e. the spray port, is connected to the nozzle of the sprinkler to facilitate the nozzle to spray water directly into the flow channel 9. The first flow channel section 901, the second flow channel section 902 and the third flow channel section 903 are all plastic tubes. The seal is arranged between the first flow channel section 901 and the second flow channel section 902 to play a shock-absorbing and sealing role for both.

[0105] Optionally, in an implementation of this embodiment, as Figure 7 As shown,

[0106] The outer wall of the first connecting pipe 801 is provided with a first connecting groove 804, the first sealing matching surface 101 of the sealing body 1 is connected to the first connecting groove 804, and the second sealing matching surface 102 of the sealing body 1 at least partially protrudes from the first connecting groove 804;

[0107] The outer side wall of the first flow channel section 901 is provided with a second connecting groove 904 , the first sealing mating surface 101 of the sealing body 1 is connected to the second connecting groove 904 , and the second sealing mating surface 102 of the sealing body 1 at least partially protrudes from the second connecting groove 904 .

[0108] The setting of the first connecting groove 804 and the second connecting groove 904 facilitates the fixing of the sealing body 1. When the first sealing mating surface 101 in the sealing body 1 is fixed by the corresponding connecting groove, the part of the second sealing mating surface 102 protruding from the connecting groove can effectively abut against the corresponding inner wall of the second connecting tube 802 and the inner wall of the second flow channel section 902, thereby better playing the role of sealing and shock absorption.

[0109] Optionally, in an implementation of this embodiment, as Figure 7 As shown,

[0110] A sealing structure 10 is arranged between the second flow channel section 902 and the third flow channel section 903. A third connecting groove 905 is arranged on the outer wall of the third flow channel section 903. The sealing structure 10 is arranged in the third connecting groove 905. A connecting pipe 906 that is plugged into and cooperates with the third connecting groove 905 is formed at the end of the second flow channel section 902. The connecting pipe 906 is abutted against the sealing structure 10.

[0111] In this embodiment, the sealing structure 10 is used to seal the connection between the second flow channel section 902 and the third flow channel section 903. The sealing structure 10 is made of elastic rubber material. The third connecting groove 905 is used to firmly fix the sealing structure 10. The connecting pipe 906 further enables the sealing structure 10 to be firmly fixed between the second flow channel section 902 and the third flow channel section 903, thereby further playing a good sealing role between the second flow channel section 902 and the third flow channel section 903.

[0112] Optionally, in an implementation of this embodiment, as Figure 4 , 6 As shown,

[0113] The valve body 803 includes a fixed ring 8031, a movable column 8032 and a limiting groove 8035;

[0114] The fixing ring 8031 ​​is fixedly connected to the pipe opening of the first connecting pipe 801 close to the second connecting pipe 802, the moving column 8032 slides through the pipe opening of the second connecting pipe 802 close to the first connecting pipe 801, a sealing gasket 8036 is arranged at the pipe opening of the second connecting pipe 802 close to the first connecting pipe 801, a flow channel connecting the first connecting pipe 801 and the second connecting pipe 802 is opened on the moving column 8032, an elastic member 8033 and a plug 8034 connected to the elastic member 8033 are arranged on the outer wall of the moving column 8032, the moving column 8032 passes through the limiting groove 8035 and one end of the elastic member 8033 is connected to the limiting groove 8035;

[0115] The valve body 803 is designed as follows: when the first connecting pipe 801 and the second connecting pipe 802 are connected, one end of the movable column 8032 contacts the fixed ring 8031, the inlet of the flow channel is located between the sealing gasket 8036 and the plug 8034, the inlet of the flow channel is in an open state, and the elastic member 8033 is compressed between the plug 8034 and the limiting groove 8035;

[0116] The first connecting pipe 801 and the second connecting pipe 802 are in a separated state, one end of the movable column 8032 is separated from the fixed ring 8031, and the elastic member 8033 pushes the plug 8034 to cover the inlet of the flow channel, and the inlet of the flow channel is in a closed state.

[0117] In this embodiment, the valve body 803 is in a connected state between the first connecting pipe 801 and the second connecting pipe 802. Figure 4 As shown, the flow channel between the first connecting pipe 801 and the second connecting pipe 802 is connected, so that the two pipes are in a connected state. At this time, the delivery pump 6 works to suck detergent from the second connecting box 4, so that the detergent enters the first connecting pipe 801 from the second connecting pipe 802, and then enters the water outlet pipe 7 along the flow channel 9 and other flow channels, and enters the clothes processing drum through the water outlet pipe 7 to participate in washing; the state of the valve body 803 at this time is that one end of the movable column 8032 is in contact with the fixing ring 8031, the inlet of the flow channel is located between the sealing gasket 8036 and the plug 8034, the inlet of the flow channel is in an open state, the elastic member 8033 is compressed between the plug 8034 and the limiting groove 8035, and the detergent flows along the second connecting pipe 802 to the inlet of the flow channel and enters the first connecting pipe 801;

[0118] When detergent needs to be added to the second connection box 4, the second connection box 4 is partially pulled out of the first connection box 3. Figure 6 , the first connecting pipe 801 and the second connecting pipe 802 are separated. At this time, the elastic member 8033, i.e. the spring, restores its elasticity, and pushes the plug 8034 so that the plug 8034 covers the inlet of the flow channel. The inlet of the flow channel is in a closed state. In this state, the dosing pump 6 cannot draw detergent from the second connecting box 4. Therefore, the setting of the valve body 803 cooperates with the working state of the second connecting box 4 being pushed in or out of the first connecting box 3, and plays a role in connecting or closing the first connecting pipe 801 and the second connecting pipe 802.

[0119] This dispensing component has two states: contact and separation. When in contact, it is in working state. At this time, the dispensing pump 6 can normally extract the required detergent from the liquid storage chamber of the second connecting box 4. The double seal can play a good sealing and shock-absorbing role, and can effectively prevent leakage regardless of whether the washing machine is in the washing state or in the power-off and static state; when the user adds detergent, the double seal is still mounted on the outer wall of the first connecting tube 801, but the second connecting box 4 is partially drawn away. At this time, the spring stretches, and the plug 8034 is pushed to cover the inlet of the flow channel. The plug 8034 and the sealing gasket 8036 jointly seal the liquid storage chamber of the second connecting box 4.

[0120] The delivery component, through multiple seals and a single sealing structure, plays a good sealing role between the various pipes in the component and also plays a good shock-absorbing role.

[0121] Embodiment 3

[0122] like Figure 2 As shown, this embodiment provides a clothes processing device, including:

[0123] The delivery component in the second embodiment;

[0124] Clothes treatment drum;

[0125] The water supply member 5, the second connection box 4 has a water inlet, and the water inlet of the second connection box 4 is connected to the output end of the water supply member 5;

[0126] The water supply member 5 and the delivery pump 6 are designed such that the delivery pump 6 draws detergent from the second connection box 4 and enters the water outlet pipe 7 under the action of the water flow provided by the water supply member 5;

[0127] The water outlet end of the water outlet pipe 7 faces the clothes processing tub.

[0128] In this embodiment, the clothing processing device is a washing machine, the first connection box 3 is a water inlet box, the second connection box 4 is a detergent dispensing box, the second connection box 4 is connected to an external faucet, i.e., a water supply component 5, for water intake, and the water intake can also wash away other substances involved in washing, such as softener, etc., which are added to the second connection box 4 in addition to detergent. The second connection box 4 is in the shape of a drawer, which can be pulled out and moved in the first connection box 3, and the second connection box 4 is used to store detergent.

[0129] like Figure 3 , 4 As shown, it is a schematic diagram of the structure of the delivery component in the working state. In the working state, the second connection box 4 is pushed into the first connection box 3 and locked, and the two boxes are connected. When the clothes need to be washed, the delivery pump 6 can extract the laundry liquid from the second connection box 4, such as Figure 5 , 6 The figure shows a schematic diagram of the structure of the second connection box 4 and the first connection box 3 in a separated state, and the separated state refers to the state in which the user partially pulls the second connection box 4 out of the first connection box 3. At this time, the dosing pump 6 cannot normally extract detergent from the second connection box 4, and the detergent is finally discharged to the clothes processing drum along the outlet pipe 7 to participate in washing.

[0130] In summary, the ingenious design of the seal and delivery assembly is:

[0131] First, by connecting the first sealing mating surface of the sealing member to the outer side wall of the first connecting pipe, when the first connecting pipe and the second connecting pipe are in a connected state, the inner side wall of the second connecting pipe is in close contact with the second sealing mating surface. When the washing machine is running at high speed, it is accompanied by vibration. When the detergent dispensing box is vibrated, the first connecting pipe and the second connecting pipe are vibrated accordingly. In this state, an annular groove is formed between the first sealing mating surface and the second sealing mating surface. When the first sealing mating surface and the second sealing mating surface are subjected to an indefinite direction of force due to the vibration of the two pipes, the annular groove is squeezed, and the volume of the groove cavity changes. The change in the volume of the groove cavity can consume external force, thereby playing a role in buffering the vibration between the two pipes. At the same time, the second sealing mating surface and the second connecting pipe are in close contact with each other with a certain margin, and the effective seal between the second connecting pipe and the first connecting pipe can be maintained even in a vibrating state, thereby effectively solving the leakage problem of the contact end when the washing machine is stationary or running at high speed, and can prevent the detergent dispensing box from loosening and leaking due to vibration, and can also solve the problem of poor sealing of the detergent dispensing box.

[0132] Second, the second sealing mating surface of the seal is inclined to form a guide slope structure. The guide slope structure can guide the detergent dispensing box when it is pushed into the water inlet box, making the pushing process smoother and easier. At the same time, the guide slope structure can make the friction surface relatively small when the detergent dispensing box is pulled out of the water inlet box, making the pulling out process more labor-saving, thereby realizing that the detergent dispensing box can be easily pulled out of the water inlet box.

[0133] Third, the opening width of the annular groove gradually decreases from the groove opening to the groove bottom, and the cross-section of the annular groove cavity is wedge-shaped. When the first sealing mating surface and the second sealing mating surface are subjected to an indefinite direction of force due to the vibration of the two tubes, the annular groove is squeezed, and the end of the wedge-shaped groove cavity close to the groove opening directly contacts the second connecting tube, and the volume is easier to change, thereby consuming external force more effectively, and effectively buffering the vibration between the two tubes. At the same time, the groove cavity cross-section of the annular groove is wedge-shaped, so that the second sealing mating surface and the second connecting tube have a certain abutment margin, and the effective seal between the second connecting tube and the first connecting tube can be maintained even in a vibrating state, thereby effectively solving the problem of contact end leakage when the washing machine is stationary or running at high speed, which can prevent the detergent dispensing box from loosening and leaking due to vibration, and can also solve the problem of poor sealing of the detergent dispensing box.

[0134] Fourth, when the dispensing component is in working state, the inner side wall of the second connecting pipe is in close contact with the second sealing mating surface of the sealing body, the valve body connects the first connecting pipe and the second connecting pipe, and the washing machine is accompanied by vibration during high-speed operation. When the detergent dispensing box is vibrated, the first connecting pipe and the second connecting pipe vibrate accordingly. In this state, an annular groove is formed between the first sealing mating surface and the second sealing mating surface. When the first sealing mating surface and the second sealing mating surface are subjected to an indefinite direction of force due to the vibration of the two tubes, the annular groove is squeezed, and the volume of the groove cavity changes. The change in the volume of the groove cavity can consume external force, thereby playing a role in buffering the vibration between the two tubes. At the same time, the second sealing mating surface and the second connecting pipe are in close contact with each other with a certain amount of margin, and the effective seal between the second connecting pipe and the first connecting pipe can be maintained even in the vibrating state, thereby effectively solving the problem of contact end leakage when the washing machine is stationary or running at high speed, and can prevent the detergent dispensing box from loosening and leaking due to vibration, and can also solve the problem of poor sealing of the detergent dispensing box. The first connecting pipe and the second connecting pipe are in a separated state, and the valve body closes the second connecting pipe. At this time, the delivery pump cannot normally extract detergent from the second connecting box, while also ensuring that the detergent will not leak during the filling process.
