DETAILED DESCRIPTION

[0053] In the description of the present invention, it should be noted that the terms "inside" and "outside" etc. indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0054] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," "in contact," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the 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 liquid 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] Example 1:

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

[0059] A sealing body 1 having a first sealing mating surface 101 and a second sealing mating surface 102 formed thereon;

[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 surface and a second axial end surface on opposite axial sides of the first sealing mating surface 101 and the second sealing mating surface 102. The guide slope extends from the first axial end surface to the second axial end surface. The outer radius of the first axial end surface is greater than the outer radius of the second axial end surface. The annular groove opens on the first axial end surface. When an external force is applied to the second sealing mating surface 102 and / or the first sealing mating surface 101, the volume of the annular groove 2 changes.

[0064] In this 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 dispensing box of the washing machine. It can play a good sealing and shock-absorbing role for the detergent dispensing box when working in the vibrating working environment of the washing machine, so as to prevent the laundry liquid from seeping into the clothing processing drum or other connecting parts, causing incomplete rinsing or damage to other connecting parts.

[0065] Specifically, 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. 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 in close contact with the second connecting pipe 802. 01 and the second sealing mating surface 102 are subjected to an uncertain direction of 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 in contact with each other 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 of the washing machine when it 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.

[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 that is inclined relative to the axis 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 of the sealing body 1 (i.e. the inner wall), and the second sealing mating surface 102 is formed on the outer ring of the sealing body 1 (i.e. the outer wall). 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 the two connection points. The advantages of the sealing member are illustrated by taking the connecting pipes 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 contact with the second sealing mating surface 102. The second sealing mating surface 102 is tilted 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 out process is more labor-saving, thereby realizing that the detergent dispensing box can be pulled out of the water inlet box freely.

[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 uncertain 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, effectively playing a role in buffering 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 in contact with 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 even in a vibrating state, thereby effectively solving the problem of leakage at the contact end of the washing machine when it 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.

[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 the first axial end face 103 to the second axial end face 104, the outer ring radius of the first axial end face 103 is greater than the outer ring radius of the second axial end face 104, and the opening of the annular groove 2 is opened on 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 on opposite axial sides of the first sealing mating surface 101 and the second sealing mating surface 102, so that the sealing body 1 and the connecting groove to which it is connected have a larger connection surface. 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 secure.

[0079] Example 2

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

[0081] The sealing member in Example 1;

[0082] A first connecting box 3, a second connecting box 4, and a dosing pump 6. The second connecting box 4 is removably connected to the first connecting box 3 and is used to store detergent. The liquid extraction end of the dosing pump 6 is connected to the second connecting box 4 for extracting detergent from the second connecting box 4. A water outlet pipe 7 is provided at the lower end of the first connecting 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 provided 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, which mainly includes the first connecting box 3, which is the water inlet box, and the second connecting box 4, which is the detergent dispensing box. The second connecting box 4 is connected to the external faucet for water intake. The incoming water can also wash away other substances involved in washing, such as softener, etc., which are added to the second connecting box 4 in addition to 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. The second connecting box 4 is used to store detergent.

[0086] like Figure 3 、 4 As shown, it is a structural diagram of the feeding 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 washing clothes, the feeding pump 6 can extract laundry liquid from the second connection box 4, as shown in FIG. Figure 5 、 6 The figure shows the structure of the second connection box 4 and the first connection box 3 in a separated state. 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.

[0087] The seal 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. 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 seal 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 communicates with the liquid extraction end of the dosing pump 6. The second connecting tube 802 is located in the second connection box 4 and communicates with 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 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 side wall of the second connecting tube 802 is in abutment 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 side 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 The figure 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 communicating state. When washing clothes, the dispensing pump 6 can extract laundry liquid 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 contact with the second sealing mating surface 102 of the sealing body 1, and the valve body 803 connects the first connecting pipe 801 and the second connecting pipe 802. 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 801 and the second connecting pipe 802 are connected. The connecting pipe 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 uncertain direction of force due to the vibration of the two pipes, 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 pipes. At the same time, the second sealing mating surface 102 and the second connecting pipe 802 are in contact with each other with a certain abutment margin, and the effective seal between the second connecting pipe 802 and the first connecting pipe 801 can be maintained even in the vibrating state, thereby effectively solving the problem of contact end leakage of the washing machine when it 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.

[0093] like Figure 6The figure shows a schematic diagram of the structure in the separated state of the second connecting box 4 and the first connecting box 3. 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 dosing 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 to play a redundancy role. 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 provided 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 sprinkler, 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 pipe 8, thereby increasing the flow rate 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,

[0102] The flow channel 9 includes a first flow channel section 901, a second flow channel section 902, and a third flow channel section 903. The first flow channel section 901, the second flow channel section 902, and the third flow channel section 903 are connected in sequence. The spray port is formed at the upper end of the first flow channel section 901, and the connection port is formed at the end of the third flow channel section 903.

[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, so that the nozzle can directly spray water 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, which plays 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 mating surface 101 of the sealing body 1 is connected to the first connecting groove 804 , and the second sealing mating surface 102 of the sealing body 1 at least partially protrudes from the first connecting groove 804 ;

[0107] A second connecting groove 904 is provided on the outer wall of the first flow channel section 901 , 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 fixation 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 protruding part of the second sealing mating surface 102 and 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 a sealing and shock-absorbing role.

[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, and a third connecting groove 905 is provided 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 fits with the third connecting groove 905 is formed at the end of the second flow channel section 902, and the connecting pipe 906 is abutted against the sealing structure 10.

[0111] In this embodiment, the sealing structure 10 is provided 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 provided to firmly fix the sealing structure 10. The setting of 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] A fixed ring 8031 ​​is fixedly connected to the opening of the first connecting tube 801 near the second connecting tube 802. A movable column 8032 slides through the opening of the second connecting tube 802 near the first connecting tube 801. A sealing gasket 8036 is provided at the opening of the second connecting tube 802 near the first connecting tube 801. A flow channel connecting the first connecting tube 801 and the second connecting tube 802 is defined on the movable column 8032. An elastic member 8033 and a plug 8034 connected to the elastic member 8033 are provided on the outer wall of the movable column 8032. The movable column 8032 extends 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 such that: when the first connecting pipe 801 and the second connecting pipe 802 are connected, one end of the movable post 8032 contacts the fixed ring 8031, and the inlet of the flow channel is located between the sealing gasket 8036 and the plug 8034. When the inlet of the flow channel is open, the elastic member 8033 is compressed between the plug 8034 and the limiting groove 8035.

[0116] When the first connecting pipe 801 and the second connecting pipe 802 are separated, 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 dosing pump 6 is working to suck detergent from the second connecting box 4, so that the detergent enters the first connecting pipe 801 through 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 suck 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 it is in contact, it is in the 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 seals 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 seals are still mounted on the outer wall of the first connecting tube 801, but the second connecting box 4 is partially pulled 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] This delivery component, through multiple sealing parts and a single sealing structure, has a good sealing effect between the various pipes in the component and also has a good shock-absorbing effect.

[0121] Example 3

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

[0123] The delivery component in Example 2;

[0124] clothes treatment drum;

[0125] The water supply component 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 component 5;

[0126] The water supply member 5 and the dosing pump 6 are designed so that the dosing pump 6 draws detergent from the second connection box 4 and the detergent 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 connecting box 3 is a water inlet box, the second connecting box 4 is a detergent dispensing box, and the second connecting box 4 is connected to an external faucet, i.e., a water supply component 5, for water intake. The incoming water can also wash away other substances involved in washing, such as softener, etc., which are added to the second connecting box 4 in addition to 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. The second connecting box 4 is used to store detergent.

[0129] like Figure 3 、 4 As shown, it is a structural diagram of the feeding 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 washing clothes, the feeding pump 6 can extract laundry liquid from the second connection box 4, as shown in FIG. Figure 5 、 6 The figure shows the structure of the second connection box 4 and the first connection box 3 in the separated state. 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. In this state, the dosing pump 6 cannot normally extract detergent from the second connection box 4. The detergent is ultimately discharged into the clothes processing drum along the water outlet pipe 7 to participate in the washing process.

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

[0131] First, by connecting the first sealing mating surface of the sealing member to the outer wall of the first connecting pipe, when the first connecting pipe and the second connecting pipe are connected, the inner wall of the second connecting pipe abuts against the second sealing mating surface. When the washing machine vibrates during high-speed operation, the detergent dispenser box causes the first connecting pipe and the second connecting pipe to 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 pipes, the annular groove is squeezed, and the volume of the groove cavity changes. The change in the groove cavity volume can consume external force, thereby buffering the vibration between the two pipes. At the same time, the second sealing mating surface and the second connecting pipe abut against each other with a certain abutting margin, which can maintain an effective seal between the second connecting pipe and the first connecting pipe even in the vibration 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.

[0132] Secondly, 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 the detergent dispensing box to 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 uncertain 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 playing a role in buffering 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 of the washing machine when it 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.

[0134] Fourth, when the dispensing assembly is in the working state, the inner side wall of the second connecting pipe is in abutment with the second sealing mating surface of the sealing body, and the valve body connects the first connecting pipe and the second connecting pipe. 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 will 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 uncertain 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 groove cavity volume 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 abutment with a certain abutment margin, and the effective seal between the second connecting pipe and the first connecting pipe can be maintained even in the vibration state, thereby effectively solving the problem of leakage at the contact end of the washing machine when it 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 dosing pump cannot normally extract detergent from the second connecting box, while also ensuring that the detergent will not leak during the filling process.
