Description

Technical Field

[0001] This utility model relates to the field of clothing processing equipment, and in particular to an additive dispensing device and clothing processing equipment. Background Technology

[0002] As people's living standards improve, clothing processing equipment, as one of the essential household appliances in modern families, has provided great convenience for people's daily lives.

[0003] Traditional garment processing equipment requires users to judge the required dosage of additives based on experience before processing begins. This increases the user's workload, and during manual addition, it is easy to cause insufficient processing due to improper dosage control, or waste due to excessive additives.

[0004] Existing technology CN111621960A discloses a detergent dispenser with low pull-out resistance, including a dispenser housing, a detergent storage box, and a detergent dispensing mechanism. One end of the insertion channel inside the detergent storage box is equipped with a check valve having an outlet A. The other end of the insertion channel has an open end for inserting a suction port. The open end of the insertion channel has a first conical surface and a sealing ring sealing surface. At least one sealing ring that can tightly fit with the sealing ring sealing surface is installed on the outer periphery of the suction port. The axial distance between the outer ring of the sealing ring closest to the check valve on the suction port and the abutting end of the suction port is 'a'. When the check valve is in the closed A outlet state, the axial distance between the contact surface of the check valve and the suction port and the open end of the sealing ring sealing surface is 'b', satisfying a≥b. When removing the detergent storage box, no vacuum resistance is generated, allowing for easier pulling out of the detergent storage box.

[0005] In the prior art CN111621960A, when the push needle and push needle sleeve are installed at the insertion channel, although the push needle sleeve extends into the insertion channel, the end face of the push needle sleeve facing the valve seat does not abut against the end face of the valve seat facing the push needle sleeve, so that there is a cavity for accommodating air between the push needle sleeve and the valve seat. The air in the cavity is trapped in the cavity under the wrapping of the insertion channel. When taking liquid, the A liquid outlet is opened by the push needle against the check valve. Since the air is trapped in the cavity between the push needle sleeve and the valve seat, the abutting action of the push needle will push the air in the cavity into the detergent storage box during the liquid taking process. Utility Model Content

[0006] The purpose of this invention is to provide an additive dispensing device and a clothing treatment equipment to solve the problem of air being injected into the liquid storage box and reduce the amount of air injected into the container.

[0007] In order to achieve the above object, the utility model adopts the following technical scheme: An additive dispensing device, comprising a receiving cavity and a container for containing an additive, the container is arranged in the receiving cavity, the container includes a container body and a liquid outlet valve arranged on the container body, the liquid outlet valve includes a valve body and a valve core, a liquid taking component is arranged in the receiving cavity, the liquid taking component includes a liquid taking pipe and a sleeve sleeved outside the liquid taking pipe, when the container is installed in place in the receiving cavity, the front end of the liquid taking pipe is inserted into the valve body and abuts against the rear end of the valve core, the front end face of the sleeve abuts against the rear end face of the valve body, when the liquid taking component does not generate an abutting force with the liquid outlet valve, the distance between the front end face of the sleeve and the rear end face of the valve body is S1, the distance between the front end face of the liquid taking pipe and the rear end face of the valve core is S2, S1 = S2; or, S1 < S2 and the front end face of the sleeve abuts against the rear end face of the valve body to form an annular contact structure, and an air leakage channel is provided at the top of the annular contact structure.

[0008] After adopting the above technical scheme, the utility model has the following advantages: During the process of installing the container into the receiving cavity, the liquid taking pipe, the valve core, the sleeve and the valve body change from a non-contact state to a contact state, and finally the inner cavity of the container body is communicated through the liquid taking pipe to reach the state where the container is installed in place. When the container is installed in place, the front end face of the sleeve abuts against the rear end face of the valve body, avoiding the formation of a cavity between the sleeve and the valve body. At the same time, the front end face of the liquid taking pipe abuts against the rear end face of the valve core, further reducing the gap between the liquid taking component and the liquid outlet valve, and reducing the possibility that air enters the container body and mixes into the additive, affecting the amount of additive taken; During the installation process of the container, there are two states between the liquid taking component and the liquid outlet valve, namely, the liquid taking component and the liquid outlet valve are not in contact, and just come into contact during the installation process and no abutting force has occurred; When the liquid taking component and the liquid outlet valve are not in contact, when the distance S1 between the front end face of the sleeve and the rear end face of the valve body is equal to the distance S2 between the rear end face of the valve core and the front end face of the liquid taking pipe, when the liquid taking component and the liquid outlet valve come into contact, the front end face of the sleeve and the rear end face of the valve body, the front end face of the liquid taking pipe and the rear end face of the valve core come into contact simultaneously, avoiding the contact between the liquid taking pipe and the valve core being later than the contact between the sleeve and the valve body, thereby avoiding the formation of a cavity between the valve body and the sleeve during the contact process of the valve core and the liquid taking pipe, and injecting the air in the cavity into the container body, and at the same time avoiding the formation of a cavity for containing air between the valve core and the liquid taking pipe, thereby reducing the possibility that air is injected into the container body during the process from the container not being installed in place to being installed in place; If S1 < S2, the abutment between the valve body and the sleeve will occur before the abutment between the valve core and the liquid taking pipe. At this time, an air leakage channel is provided on the annular contact structure formed by the front end face of the sleeve abutting against the rear end face of the valve body. During the contact process of the valve core and the liquid taking pipe, the air is discharged from the air leakage channel between the sleeve and the valve body, avoiding the possibility that air is injected into the container body during the contact and abutment process of the liquid taking pipe and the valve core. Reducing the possibility that air is injected into the container body, thereby avoiding the mixing of air and the additive in the container body, and then affecting the actual amount of the additive taken out for use; Improving the consistency between the dose of the additive taken out for use and the set dose taken out for use.

[0009] Further, S1 = S2, the front end face of the liquid extraction tube is flush with the front end face of the sleeve, and the rear end face of the valve body is flush with the rear end face of the valve core.

[0010] With the foregoing technical solution, when S1 = S2, the front end face of the liquid extraction tube is set flush with the front end face of the sleeve, and the rear end face of the valve body is also set flush with the rear end face of the valve core, thereby avoiding the formation of a cavity for accommodating air between the valve body and the sleeve or between the valve core and the liquid extraction tube.

[0011] Further, S1 = S2, the front end face of the liquid extraction tube protrudes from the front end face of the sleeve by a distance of L1, and the distance between the rear end face of the valve core and the rear end face of the valve body is L2, and L1 = L2.

[0012] With the foregoing technical solution, the liquid extraction tube and the sleeve, and the valve core and the valve body may not be flush, but at this time, the distance L1 by which the front end face of the liquid extraction tube protrudes from the front end face of the sleeve needs to be equal to the distance L2 between the rear end face of the valve core and the rear end face of the valve body, so that as the container is installed, the protruding liquid extraction tube first extends into the valve body. During the process of the liquid extraction tube and the valve core approaching each other, air flows out between the sleeve and the valve body, and the liquid extraction tube and the valve core, and the sleeve and the valve body can be in contact at the same time, avoiding air being injected into the container body during the contact between the liquid extraction assembly and the liquid outlet valve.

[0013] Further, a first sealing member is provided at the front end of the liquid extraction tube, and the distance between the first sealing member and the front end face of the liquid extraction tube is L3, and L1 < L3.

[0014] With the foregoing technical solution, the front end of the liquid extraction tube and the tube sleeve are sealed and installed through the first sealing member, improving the sealing effect between the liquid extraction tube and the sleeve. When the front end of the liquid extraction tube protrudes from the sleeve, L2 < L3. After the liquid extraction tube extends into the valve body, the air between the front end face of the liquid extraction tube and the valve core is discharged through the gap between the outer peripheral wall of the liquid extraction tube and the inner wall of the valve body. After the front end face of the liquid extraction tube abuts against the rear end face of the valve core, the first sealing member seals the outer peripheral wall of the liquid extraction tube and the inner wall of the valve body, avoiding air from entering the container body from the rear end of the valve body and the outer peripheral wall of the liquid extraction tube.

[0015] Further, S1 < S2, the front end face of the sleeve and the rear end face of the valve body abut against each other before the front end face of the liquid extraction tube and the rear end face of the valve core.

[0016] With the foregoing technical solution, when S1 < S2, the front end face of the sleeve and the rear end face of the valve body abut against each other before the front end face of the liquid extraction tube and the rear end face of the valve core. During the abutting process of the front end face of the liquid extraction tube and the rear end face of the valve core, the air between the front end face of the liquid extraction tube and the rear end face of the valve core flows out through the air leakage channel between the sleeve and the valve core, avoiding the air between the front end face of the liquid extraction tube and the rear end face of the valve core from being injected into the container body.

[0017] Further, the front end face of the liquid extraction tube is in contact with the rear end face of the valve core to reduce the air between the two.

[0018] Adopting the foregoing technical solution, when the front end face of the liquid extraction tube abuts against the rear end face of the valve core, the two are in contact through the end face, reducing the air between the front end face and the rear end face of the liquid extraction tube, and further preventing air from being injected into the container body.

[0019] Further, S1 < S2, the air leakage channel includes a vent hole provided at the front end of the sleeve or the rear end of the valve body, and the cavity formed by the abutment of the sleeve and the valve body communicates with the external space of the sleeve through the vent hole.

[0020] Adopting the foregoing technical solution, S1 < S2, the vent hole of the air leakage channel is provided at the front end of the sleeve, so that the vent hole communicates the cavity formed after the sleeve and the valve body abut and the external space of the sleeve. The vent hole can also be provided at the rear end of the valve body to communicate the cavity formed after the sleeve and the valve body abut and the external space of the sleeve. During the process of the front end face of the liquid extraction tube abutting against the rear end face of the valve core, air is discharged from the vent hole, preventing air from being injected into the container body.

[0021] Further, S1 < S2, the air leakage channel includes a vent groove provided on the front end face of the sleeve or the rear end of the valve body, and the cavity formed by the abutment of the sleeve and the valve body communicates with the external space of the sleeve through the vent groove.

[0022] Adopting the foregoing technical solution, S1 < S2, the vent groove of the air leakage channel is provided at the front end of the sleeve, so that the vent groove communicates the cavity formed after the sleeve and the valve body abut and the external space of the sleeve. The vent groove can also be provided at the rear end of the valve body to communicate the cavity formed after the sleeve and the valve body abut and the external space of the sleeve. During the process of the front end face of the liquid extraction tube abutting against the rear end face of the valve core, air is discharged from the vent groove, preventing air from being injected into the container body.

[0023] Further, S1 < S2, the air leakage channel includes a vent hole. The rear end face of the valve body is provided with a first vent groove, and the front end face of the sleeve is provided with a second vent groove. When the rear end face of the valve body abuts against the rear end face of the sleeve, the first vent groove and the second vent groove are combined to form a vent hole.

[0024] Adopting the foregoing technical solution, S1 < S2, as the container is installed, the first vent groove and the second vent groove form a vent hole when the sleeve and the valve body abut. After the sleeve and the valve body abut first, the air between the liquid extraction tube and the valve core is discharged from the vent hole, preventing air from being injected into the container body.

[0025] Further, a first seal is provided on the outer peripheral side of the front end of the liquid extraction tube for sealing cooperation with the sleeve or the valve body.

[0026] Using the aforementioned technical solution, the outer periphery of the front end of the liquid extraction tube is sealed with the sleeve through the first sealing element to avoid excessive air between the liquid extraction tube and the sleeve. The outer periphery of the front end of the liquid extraction tube is sealed with the valve body through the first sealing element to improve the sealing effect and prevent air from the outside space of the sleeve from entering the valve body from the leakage channel during the compression process.

[0027] Furthermore, the liquid collection tube has a through-hole on its side, and a first sealing element is provided on both sides of the liquid collection hole.

[0028] Using the aforementioned technical solution, the liquid inlet is located on the side of the liquid inlet tube to avoid the air between the liquid inlet tube and the valve core being unable to be discharged to the outer space of the sleeve during the installation process due to the liquid inlet being located on the end face. Both sides of the liquid inlet are sealed by the first sealing element to prevent air from being trapped and to prevent the additive from flowing along the axial direction of the liquid inlet tube and being trapped between the outer peripheral wall of the liquid inlet tube and the valve body or sleeve.

[0029] Furthermore, the outer diameter of the portion of the liquid collection tube located in front of the liquid collection port is substantially equal to the inner diameter of the sleeve.

[0030] By adopting the aforementioned technical solution, the outer diameter of the part of the liquid collection tube located in front of the liquid collection port is set to be basically equal to the inner diameter of the sleeve, so that the front end of the liquid collection tube fits more tightly with the inner wall of the sleeve, avoiding the presence of residual air in the space between the liquid collection tube and the sleeve, or the presence of a certain space causing the additive at the liquid collection port to overflow.

[0031] Furthermore, the outer peripheral side of the rear end of the valve core is provided with a second sealing element that seals with the valve body.

[0032] Using the aforementioned technical solution, the outer peripheral side of the rear end of the valve core is sealed to the valve body through a second sealing element, which increases the difficulty for air to enter the container body from between the valve core and the valve body. At the same time, it ensures that the additives in the container body do not leak out from between the valve core and the valve body.

[0033] Furthermore, the outer diameter of the portion of the valve core located behind the second seal is substantially equal to the inner diameter of the valve body.

[0034] By adopting the aforementioned technical solution, the outer diameter of the part of the valve core located behind the second seal is set to be basically equal to the inner diameter of the valve core, so that the rear end of the valve core fits more tightly with the inner wall of the valve cavity, avoiding the presence of residual air or additive overflow due to a certain space between the valve core and the valve cavity.

[0035] Furthermore, the valve body is provided with a valve cavity, and the valve core reciprocates within the valve cavity. The side of the valve cavity is provided with a liquid outlet that penetrates the valve body and is connected to the inner cavity of the container body. The liquid taking tube is provided with a liquid taking channel that is closed at the front end, and the side of the liquid taking channel is provided with a liquid taking port that penetrates the liquid taking tube. The liquid taking port and the liquid outlet are connected to each other to achieve liquid taking.

[0036] The aforementioned technical solution includes a valve cavity on the valve body to facilitate the reciprocating movement of the valve core. This allows the valve core to close the outlet on the valve body when the liquid taking component and the liquid outlet valve are closed. After the liquid outlet is set, liquid is taken through the liquid taking port and the liquid outlet in relative communication. Compared with the prior art CN111621960A, this solution changes the extraction path of the additive during liquid taking, preventing air from entering the container body during the liquid taking process. During the liquid taking process, both sides of the liquid taking port are sealed by the first sealing element to prevent the additive from flowing to both sides from the liquid outlet and the liquid taking port.

[0037] To achieve the above objectives, the present invention also adopts the following technical solution: a clothing processing device, including a body, wherein the body is provided with an additive dispensing device.

[0038] By adopting the aforementioned technical solution, an additive dispensing device is installed on the machine body to prevent air from being forced into the container body. This ensures that when the additive is used to treat clothes, the amount of additive taken out will not be mixed with air, thus preventing the actual amount of additive taken out from being less than the amount set by the machine body, thereby avoiding inadequate treatment of clothes.

[0051] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0052] like Figure 1 As shown, this utility model provides an additive dispensing device, including a receiving cavity 1 and a container 2 for holding the additive, the container 2 being disposed within the receiving cavity 1, as shown. Figure 1 and Figure 2As shown, container 2 includes a container body 21 and a liquid outlet valve 22 disposed on the container body 21. The liquid outlet valve 22 includes a valve body 221 and a valve core 222. A liquid extraction assembly 23 is provided in the receiving cavity 1. The liquid extraction assembly 23 includes a liquid extraction tube 232 and a sleeve 231 sleeved outside the liquid extraction tube 232. When installing container 2, container 2, carrying the liquid outlet valve 22, gradually approaches the liquid extraction assembly 23 from front to back until it abuts against the liquid extraction assembly 23. After the liquid outlet valve 22 abuts against the liquid extraction assembly 23, the valve body 221 pushes the sleeve 231 from front to back, so that the liquid extraction tube 232 extends into the valve body 221 and communicates with the inner cavity of the container body 21. Container 2 is then installed and in place. Therefore, after container 2 is installed in place, the front end face of the sleeve 231 abuts against the rear end face of the valve body 221, and the liquid extraction tube 232 extends into the valve body 221. Furthermore, the front end face of the liquid extraction tube 232 abuts against the rear end face of the valve core 222, and the sleeve 231 abuts against the valve body 221, and the liquid extraction tube 232 abuts against the valve core 222 at their end faces, reducing the cavity of residual air between the sleeve 231 and the valve body 221, and preventing air from being injected into the container body 21. When the liquid extraction tube 232 and the inner cavity of the container body 21 are not connected, it means that the container 2 is not installed in place. During the process of installing the container 2 from not being installed in place to being installed in place, the liquid extraction component 23 and the liquid outlet valve 22 are never in abutting state.

[0053] In this embodiment, when the liquid taking component 23 and the liquid dispensing valve 22 are not in contact, such as Figure 3 As shown, the distance between the front end face of the sleeve 231 and the rear end face of the valve body 221 is S1, and the distance between the front end face of the liquid taking tube 232 and the rear end face of the valve core 222 is S2. S1 = S2, so that when the liquid taking component 23 and the liquid outlet valve 22 are from the un-closed state to the closed state, the sleeve 231 and the valve body 221, and the liquid taking tube 232 and the valve core 222 are closed simultaneously. During the closed process, the air between the front end face of the liquid taking tube 232 and the rear end face of the valve core 222 is discharged from the front end face of the sleeve 231 and the rear end face of the valve core 222, reducing the air remaining between the front end face of the sleeve 231 and the rear end face of the valve body 221, and reducing the air being forced into the container body 21.

[0054] like Figure 3 As shown, when S1 = S2, the front end face of the liquid taking tube 232 is flush with the front end face of the sleeve 231, and the rear end face of the valve body 221 is flush with the rear end face of the valve core 222. This ensures that after the front end face of the liquid taking tube 232 and the rear end face of the valve core 222, and the front end face of the sleeve 231 and the rear end face of the valve body 221 simultaneously come into contact, as the container 2 continues to be installed, the valve body 221 and the sleeve 231 slide backward relative to the front end face of the liquid taking tube 232. The liquid taking tube 232 pushes the valve core 222 and extends into the valve body 221, preventing air from being forced into the container body 21. Alternatively, as... Figure 4As shown, the front end face of the liquid extraction tube 232 protrudes from the front end face of the sleeve 231, and the protruding distance is L1. At this time, the rear end face of the valve core 222 is located behind the rear end face of the valve body 221, and the distance between the rear end face of the valve core 222 and the rear end face of the valve body 221 is L2, and L1 = L2. As the container 2 is continuously installed, the front end of the liquid extraction tube 232 first extends into the valve body 221, and then during the process of the front end face of the sleeve 231 and the rear end face of the valve core 222, and the front end face of the liquid extraction tube 232 and the rear end face of the valve core 222 contacting simultaneously, the air between the front end face of the liquid extraction tube 232 and the rear end face of the valve core 222 is discharged from the gap between the outer peripheral wall of the liquid extraction tube 232 and the inner wall of the valve body 221, preventing air from being injected into the container body 21.

[0055] To further prevent air from being injected into the container body 21 due to the front end of the liquid extraction tube 232 extending into the valve body 221 first, as Figure 4 and Figure 5 shown, a first seal 233 is provided at the front end of the liquid extraction tube 232. The distance between the first seal 233 and the front end face of the liquid extraction tube 232 is L3, and L3 > L1. When the front end face of the sleeve 231 contacts the rear end face of the valve body 221 and the front end face of the liquid extraction tube 232 does not contact the rear end face of the valve core 222, the first seal 233 is located inside the sleeve 231, and air can be discharged from the gap between the outer peripheral wall of the liquid extraction tube 232 and the inner wall of the valve body 221. When the front end face of the liquid extraction tube 232 contacts the rear end face of the valve core 222 and then the container 2 is continuously installed, the first seal 233 extends into the valve body 221 to seal the outer peripheral wall of the front end of the liquid extraction tube 232 and the inner wall of the valve body 221, preventing additives from overflowing and being wasted between the outer peripheral wall of the front end of the liquid extraction tube 232 and the inner wall of the valve body 221 during the liquid extraction process where the liquid extraction tube 232 is connected to the inner cavity of the container body 21.

[0056] In another embodiment, as Figure 4 shown, when the liquid extraction assembly 23 and the liquid outlet valve 22 are not in contact, the distance between the front end face of the sleeve 231 and the rear end face of the valve body 221 is S1, and the distance between the front end face of the liquid extraction tube 232 and the rear end face of the valve core 222 is S2, and S1 < S2. In this case, as the liquid outlet valve 22 is continuously installed, as Figure 5 and Figure 6 shown, the front end face of the sleeve 231 and the rear end face of the valve body 221 contact first before the front end face of the liquid extraction tube 232 and the rear end face of the valve core 222. The front end face of the sleeve 231 and the rear end face of the valve body 221 contact first and form an annular contact structure 3. A leakage channel is provided at the top of the annular contact structure 3, so that the gas in the cavity formed by the front end face of the sleeve 231 and the rear end face of the valve body 221 contacting first is discharged from the leakage channel, reducing the air injected into the container body 21 during the process of the front end face of the liquid extraction tube 232 and the rear end face of the valve core 222 contacting.

[0057] Specifically, as Figure 6 As shown, the air leakage channel includes a vent hole 31, which is located at the front end of the sleeve 231 or at the rear end of the valve body 221. This allows the cavity formed by the sleeve 231 and valve body 221 abutting together to communicate with the external space of the sleeve 231 through the vent hole 31. The vent hole 31 allows air compressed during the contact between the liquid extraction tube 232 and the valve core 222 to be discharged, preventing air from entering the container body 21. Alternatively, as... Figure 7 As shown, the air leakage channel includes a vent groove 32, which is located on the front end face of the sleeve 231 or on the rear end face of the valve body 221. This allows the cavity formed by the contact between the sleeve 231 and the valve body 221 to communicate with the external space of the sleeve 231 through the vent groove 32. The vent groove 32 allows air accumulated during the contact between the liquid extraction tube 232 and the valve core 222 to be discharged, preventing air from entering the container body 21. Figure 8 As shown, the leakage channel can also be a vent hole 33, which is formed by splicing a first vent groove 331 and a second vent groove 332. Specifically, the rear end face of the valve body 221 is provided with a first vent groove 331, and the front end face of the sleeve 231 is provided with a second vent groove 332. The front end face of the sleeve 231 abuts against the rear end face of the valve body 221 first, so that the first vent groove 331 and the second vent groove 332 merge to form a vent hole 33. The air between the front end face of the liquid taking tube 232 and the rear end face of the valve core 222 is discharged from the vent hole 33 during the contact process between the front end face of the liquid taking tube 232 and the rear end face of the valve core 222, thus preventing air from entering the container body 21.

[0058] To further improve the sealing effect between the liquid extraction tube 232 and the sleeve 231 or valve body 221, such as Figure 6 and Figure 9 As shown, a first sealing element 233 is provided at the front end of the liquid extraction tube 232. When the container 2 is not installed, the first sealing element 233 is sealed between the outer peripheral wall of the front end of the liquid extraction tube 232 and the inner wall of the sleeve 231, preventing air from entering between the liquid extraction tube 232 and the sleeve 231, or preventing residual additives in the liquid extraction tube 232 from overflowing from the front end of the liquid extraction tube 232. During the installation of the container 2, when the first sealing element 233 enters the valve body 221 along with the liquid extraction tube 232, the first sealing element 233 is sealed with the inner wall of the valve body 221, preventing air from entering the container body 21 from the outer peripheral wall of the liquid extraction tube 232 and the inner wall of the valve body 221. At the same time, it prevents the additives in the container body 21 from flowing out from the outer peripheral wall of the liquid extraction tube 232 and the valve body 221 and being wasted.

[0059] When the front end face of the liquid dispensing tube 232 abuts against the rear end face of the valve core 222, the end faces are in contact, thereby reducing the air between the front end face of the liquid dispensing tube 232 and the rear end face of the valve core 222, and reducing the amount of air entering the container body 21.

[0060] To facilitate the extraction of additives from the inner cavity of the container body 21 through the liquid extraction tube 232, such as Figure 9 As shown, the liquid extraction tube 232 has a liquid extraction port 234 that penetrates the inner and outer walls of the liquid extraction tube 232. As the liquid extraction tube 232 extends into the valve body 221, the container 2 is in the installed state only after the liquid extraction port 234 is connected to the inner cavity of the container body 21. At this time, the additive can be taken out from the inner cavity of the container body 21, the liquid extraction port 234 and the liquid extraction tube 232 for use. In this embodiment, there are two first sealing members 233, which are distributed on both sides of the liquid extraction port 234 to prevent the additive from overflowing from the outer wall of the liquid extraction tube 232 from the liquid extraction port 234 during the liquid extraction process and thus being wasted.

[0061] To improve the sealing effect between the front end of the liquid collection tube 232 and the inner wall of the sleeve 231, the outer diameter of the portion of the liquid collection tube 232 located in front of the liquid collection port 234 is approximately equal to the inner diameter of the sleeve 231. This reduces the gap between the front end of the liquid collection tube 232 and the sleeve 231, and also reduces the possibility of additives in the liquid collection tube 232 flowing out from the front end and being wasted. It should be noted that "approximately equal" here means that after the portion of the liquid collection tube 232 located in front of the liquid collection port 234 is fitted with the sleeve 231, the gap between the outer peripheral wall of the liquid collection tube 232 and the inner wall of the sleeve 231 is minimized without affecting the relative movement of the sleeve 231 and the liquid collection tube 232.

[0062] To prevent the additives inside the container body 21 from overflowing from the rear end face of the valve body 221, such as Figure 9 As shown, the outer peripheral side of the rear end of the valve core 222 is provided with a second sealing element 224 that seals with the valve body 221. The sealing effect is improved by the sealing of the second sealing element 224, and the additive is prevented from overflowing from the outer peripheral wall of the rear end of the valve core 222 and the inner wall of the valve body 221 and being wasted.

[0063] In this embodiment, the outer diameter of the portion of the valve core 222 located behind the second seal 224 is substantially equal to the inner diameter of the valve body 221, thereby preventing air from the rear side of the rear end face of the valve core 222 from being forced into the container body 21 between the outer peripheral wall of the valve core 222 and the inner wall of the valve body 221.

[0064] In another embodiment, if Figure 9As shown, the valve body 221 has a valve cavity 223, and the valve core 222 reciprocates within the valve cavity 223. The side of the valve cavity 223 has a liquid outlet 225 penetrating the valve body 221, which communicates with the inner cavity of the container body 21. The liquid extraction tube 232 has a liquid extraction channel 235 with a closed front end, and a liquid extraction port 234 penetrating the liquid extraction tube 232 is located on the side of the liquid extraction channel 235. With the installation of the container 2, when the liquid extraction port 234 is in relative communication with the liquid outlet 225, the container 2 is in place to achieve liquid extraction. In this embodiment, the front end of the liquid extraction tube 232 is closed, and the additive directly enters the liquid extraction channel 235 from the liquid outlet 225 and the liquid extraction port 234, avoiding contact between the additive and the outer peripheral wall of the front end of the liquid extraction tube 232.

[0065] This utility model also provides a garment processing device, including a body, wherein the body is equipped with an additive dispensing device. By installing the additive dispensing device on the body, air is prevented from being forced into the container body 21, so that when the additive is used to process the garment, the dispensed additive will not be mixed with air, resulting in the actual amount of additive dispensed being less than the amount set by the body, thereby avoiding inadequate garment processing.

[0066] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
