Description

Technical Field

[0001] The present invention relates to the field of clothing processing equipment, in particular to an additive dispensing device and clothing processing equipment. Background Art

[0002] With the improvement of people's living standards, clothing processing equipment, as one of the indispensable household appliances in modern families, provides great convenience for people's daily life.

[0003] When treating clothes with traditional clothing treatment equipment, users are required to judge the dosage of additives required based on experience before starting the treatment, which increases the workload of users. In addition, during the manual addition process, improper control of the dosage may result in too little additive and inadequate treatment, or too much additive and waste.

[0004] The prior art CN115387085A discloses a liquid-conducting plug-in structure, which is arranged on an additive delivery module and can be inserted into the liquid storage box through the delivery port of the liquid storage box to communicate with the additive inside the liquid storage box. The liquid-conducting plug-in structure is provided with a detection device for detecting the type and / or the residual amount of the additive in the liquid storage box. The prior art CN115387085A also provides an additive delivery module, including a liquid storage box with a closed chamber for storing additives, and a plug-in slot for installing the liquid storage box, and the plug-in slot is provided with the liquid-conducting plug-in structure. The prior art CN115387085A also specifically discloses a liquid-conducting plug-in pipe, which includes a liquid-conducting pipe section and a plug-in pipe section with a reduced outer diameter connected to the end of the liquid-conducting pipe. The side wall of the plug-in pipe section is provided with a liquid-conducting port. When taking liquid, the plug-in pipe section with the liquid-conducting port extends into the plug-in slot, so that the additive flows into the liquid-conducting plug-in pipe through the liquid-conducting port, thereby leading the additive in the liquid storage box out for use.

[0005] In the prior art CN115387085A, the liquid guide port is located on the plug-in tube section with a reduced outer diameter. When guiding liquid, the plug-in tube section extends into the plug-in groove, and the additive in the plug-in groove is wrapped around the peripheral wall and end face of the plug-in tube section and enters the inside of the plug-in tube section from the liquid guide port. Since the additive wraps around the peripheral wall and end face of the plug-in tube section, when the plug-in tube section is taken out of the liquid storage box, the additive wrapped around the outer wall and end face of the plug-in tube section is easy to drip. At the same time, since the liquid guide port is exposed after the liquid guide plug-in tube is taken out, the additive in the plug-in tube section and the liquid guide tube section is easy to flow out from the liquid guide port and drip. Summary of the invention

[0006] The purpose of the present invention is to provide an additive dispensing device and a clothing processing device to solve the problem of additive dripping and avoid dripping caused by the additive adhering to the outer wall and being exposed after disassembly.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an additive delivery device, comprising a accommodating chamber and a container arranged in the accommodating chamber for containing the additive, the container is provided with a liquid outlet valve, a liquid collection component is provided in the accommodating chamber, the liquid collection component comprises a liquid collection tube and a tube sleeve, a liquid collection port is provided on the side of the liquid collection tube, the front end of the tube sleeve is abutted against the liquid outlet valve, the tube sleeve is sleeved on the outer periphery of the liquid collection tube and slides relative to the liquid collection tube to open or close the liquid collection port, the liquid collection tube has an initial state and a liquid collection state, the tube sleeve closes the liquid collection port when the liquid collection tube is in the initial state, and the liquid outlet valve is inserted into the liquid collection tube when the liquid collection tube is in the liquid collection state and the liquid outlet valve is pushed open to connect the liquid collection port with the inner cavity of the container, and the outer peripheral wall of the liquid collection tube is sealed with the liquid outlet valve.

[0008] After adopting the above technical scheme, the present invention has the following advantages: the liquid collection component is configured as a liquid collection tube and a tube sleeve, and the tube sleeve is used to cover the liquid collection tube, so that the additive in the liquid collection tube is prevented from flowing out from the liquid collection port when the liquid collection tube is in the initial state, thereby preventing dripping; when the liquid collection tube is in the liquid collection state, the liquid collection tube extends into the liquid outlet valve to push the liquid outlet valve open, so that the liquid collection port is connected with the inner cavity of the container, and then the additive in the container is taken out; the outer wall of the liquid collection tube is shielded by the liquid outlet valve, so that the additive is prevented from adhering to the outer periphery of the liquid collection tube, thereby preventing the liquid collection tube from moving. Liquid dripping after the liquid outlet valve is opened. Compared with the prior art CN115387085A, when the liquid taking tube is in the liquid taking state, the liquid taking port is connected with the inner cavity of the container through the liquid outlet valve, and the outer peripheral wall of the liquid taking tube is wrapped by the liquid outlet valve to reduce the adhesion of additives to the outer peripheral wall of the liquid taking tube. When the liquid taking tube is in the initial state, the liquid taking port is blocked by the pipe sleeve to prevent the additives in the liquid taking tube from flowing out of the liquid taking port, thereby preventing the additives from dripping due to adhesion to the outer peripheral wall of the liquid taking tube, or the additives in the liquid taking tube from dripping due to the exposure of the liquid taking port.

[0009] Furthermore, a first seal is provided on the outer periphery of the liquid taking tube, and the first seal is located at the front and rear sides of the liquid taking port. The first seal is sealed with the liquid outlet valve when the liquid taking tube is in the liquid taking state, and is sealed with the tube sleeve when the liquid taking tube is in the starting state.

[0010] By adopting the above-mentioned technical solution, the first sealing component is arranged on the outer periphery of the liquid collection tube. When the liquid collection tube is in the initial state of discharging liquid, the first sealing component contacts and seals the inner wall of the tube sleeve, further reducing the axial flow of the additive from the liquid collection port to the liquid collection tube and causing dripping. When the liquid collection tube is in the liquid collection state, the first sealing component cooperates with the liquid outlet valve seal to prevent the additive at the liquid collection port from flowing axially, thereby preventing the additive from adhering to the outer wall of the liquid collection tube and causing dripping. The sealing of the first sealing component improves the sealing effect, ensuring that the additive does not contact the outer peripheral wall of the liquid collection tube and does not flow out from the liquid collection port, thereby preventing the additive from dripping.

[0011] Furthermore, a liquid level detection probe is embedded in the tube body of the liquid collection tube, and a detection cavity is provided at the front end of the liquid collection tube. The detection end of the liquid level detection probe extends into the detection cavity. The detection cavity is connected with the inner cavity of the container when the liquid collection tube is in the liquid collection state. When the liquid collection tube is in the starting state, the tube sleeve is reset relative to the liquid collection tube and sealed to close the detection cavity.

[0012] By adopting the above-mentioned technical solution, after the liquid taking tube is extended into the inner cavity of the container, the detection cavity and the liquid level detection probe are used to detect whether there are additives in the container, so as to facilitate confirmation of whether there are additives in the container, so that the user can confirm whether the container needs to be replaced, and at the same time avoid affecting the clothing treatment effect due to lack of additives when the user directly uses the clothing treatment device. When the liquid taking tube is in the starting state, the tube sleeve is reset and the detection cavity is sealed to avoid the additive in the detection cavity from dripping from the liquid taking tube, thereby reducing the waste of additives.

[0013] Furthermore, a second sealing member is provided on the outer periphery of the liquid collection tube, and the second sealing member is located at the front and rear sides of the detection cavity. When the liquid collection tube is in the initial state, the second sealing member seals with the tube sleeve to close the detection cavity.

[0014] By adopting the above-mentioned technical solution, a second sealing member is provided on the outer periphery of the liquid collection tube, and the second sealing member is sealed on the front and rear sides of the detection cavity. The second sealing member increases the sealing effect between the rear end of the liquid collection tube and the liquid outlet valve, thereby preventing the additive from flowing from the detection cavity to the outer peripheral wall of the liquid collection tube during the conversion of the liquid collection tube from the liquid collection state to the initial state, causing the additive to adhere to the outer wall of the liquid collection tube, reducing the dripping of the additive, and thus reducing the waste of the additive.

[0015] Furthermore, the liquid outlet valve includes a valve body and a valve core, the valve body is provided with a valve cavity, the valve core reciprocates in the valve cavity, the valve body is provided with a detection port connecting the valve cavity with the inner cavity of the container, and when the liquid collection tube is in the liquid collection state, the detection cavity is connected with the inner cavity of the container through the valve cavity and the detection port.

[0016] By adopting the above-mentioned technical solution, when the container is installed, the rear end face of the valve core abuts against the front end face of the liquid collection tube. As the container and the liquid collection tube are plugged in, the tube sleeve moves backward relative to the liquid collection tube until the liquid collection port is connected with the inner cavity of the container. At the same time, the detection cavity is connected with the inner cavity of the container through the valve cavity and the detection port on the valve body, which is convenient for the liquid level detection probe to detect whether there are additives in the inner cavity of the container. The reciprocating motion of the valve core relative to the valve cavity facilitates the opening and closing of the liquid outlet valve. The setting of the detection port facilitates the filling of additives in the detection cavity, thereby improving the accuracy of the liquid level detection probe.

[0017] Furthermore, the rear end of the valve body is provided with an insertion port for inserting a liquid collection tube into the valve cavity, and the side wall of the valve body is provided with a liquid inlet and outlet, which is located between the detection port and the insertion port. When the liquid collection tube is in a liquid collection state, the liquid inlet and outlet are connected to the liquid collection port, and the detection port and the detection cavity at least partially overlap in the axial direction of the valve core.

[0018] The above-mentioned technical scheme is adopted, by arranging an insertion interface at the rear end of the valve body, so that the liquid extraction tube can be inserted into the valve cavity relative to the tube sleeve, and the side wall of the valve body is provided with a liquid inlet and outlet. In the liquid extraction state, the liquid inlet and outlet are connected with the liquid extraction port, so as to facilitate the removal of additives. The liquid inlet and outlet are arranged between the insertion interface and the detection port. When the liquid level detection probe detects that there is an additive in the container, the liquid extraction tube can remove the additive from the inner cavity of the container, thereby improving the consistency of the detection result and the liquid extraction result, and avoiding the discrepancy between the detection result and the actual liquid extraction result. In the liquid extraction state, the detection port and the detection cavity overlap on the axis, thereby avoiding that the additive cannot flow into the detection cavity and affect the detection result.

[0019] Furthermore, the accommodating chamber is provided with a push-lock for locking the container, the distance between the first sealing member located at the rear side of the liquid inlet and the liquid outlet is X, and the travel of the container from the locked state to the unlocked state of the push-lock is Y, and X≥Y.

[0020] By adopting the aforementioned technical solution, the distance X between the first sealing member located at the rear side of the liquid intake port and the liquid outlet inlet is set to be greater than the stroke Y of the reciprocating motion of the pushing block. In the process of unlocking the container by pushing the spring lock, the first sealing member located at the rear side of the liquid intake port is always sealed at the rear side of the liquid outlet inlet, thereby improving the sealing effect of the rear side of the liquid outlet inlet and preventing the additive in the inner cavity of the container from flowing from the liquid outlet inlet to the plug-in port and overflowing and being wasted.

[0021] Furthermore, a guide base is provided at the front end of the valve body, the front end of the valve core passes through the guide base and cooperates with the guide base, and the valve core reciprocates relative to the guide base.

[0022] By adopting the above-mentioned technical solution, the valve core moves toward the tail end of the valve body under the insertion of the liquid extraction tube, so as to facilitate the connection between the liquid outlet and the liquid extraction port. During the movement of the valve core, the front end of the valve core is supported by the guide base to prevent the rear end of the valve core from deflecting due to lack of support, thereby affecting the sealing effect between the outer peripheral wall at the rear end of the valve core and the inner wall of the valve cavity.

[0023] Furthermore, an elastic reset member for driving the valve core to reset is provided in the valve cavity, and an accommodating cavity for accommodating the elastic reset member is formed between the rear end of the guide base and the inner wall of the valve cavity.

[0024] By adopting the above-mentioned technical solution, the reciprocating motion of the valve core in the valve cavity is reset by the elastic reset member, so as to avoid the valve core failing to reset, causing the additive to flow out of the plug-in interface of the valve body and cause waste. The front end of the elastic reset member is accommodated and positioned by the accommodating cavity, reducing the possibility of the elastic reset member detaching from the guide base and improving the stability of the elastic reset member.

[0025] Furthermore, a stop rib is provided at the front of the valve core, and a stop step is provided at the front of the guide base. When the liquid extraction tube is in the starting state, the stop rib abuts against the stop step.

[0026] By adopting the above-mentioned technical solution, the front end of the valve core is positioned by the stop rib and the stop step to prevent the front end of the valve core from moving into the valve cavity during the valve core resetting process, resulting in a lack of support for the front end of the valve core, and to prevent the rear end of the valve core from lacking support and affecting the sealing effect.

[0027] In order to achieve the above-mentioned object, the present invention adopts the following technical scheme: a clothes processing device, comprising a machine body, wherein an additive delivery device is provided on the machine body

[0028] By adopting the above-mentioned technical solution, the additive delivery device is installed on the body of the clothing processing device, which is convenient for taking the additive and avoids the waste caused by the dripping of the additive. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The technical solution of the present invention is described in detail with specific embodiments below. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0042] like Figure 1 and Figure 2 As shown, the present invention provides an additive delivery device, comprising a receiving chamber 1 and a container 2 for containing additives arranged in the receiving chamber 1, the container 2 is provided with a mounting through hole 21, a liquid outlet valve 4 is provided at the mounting through hole 21, a liquid collection component 3 is provided in the receiving chamber 1; the liquid collection component 3 comprises a liquid collection tube 32 and a tube sleeve 31, a liquid collection port 321 is provided on the side of the liquid collection tube 32, the tube sleeve 31 is sleeved on the outer periphery of the liquid collection tube 32 and slides relative to the liquid collection tube 32 in the front-to-back direction to open or close the liquid collection port 321; specifically, the liquid collection tube 32 has an initial state and a liquid collection state, such as Figure 3 As shown, the sleeve 31 closes the liquid taking port 321 when the liquid taking pipe 32 is in the initial state. Figure 4As shown, when the liquid taking tube 32 is in the liquid taking state, the liquid outlet valve 4 is inserted and the liquid outlet valve 4 is pushed open so that the liquid taking port 321 is connected with the inner cavity of the container 2, and the outer peripheral wall of the liquid taking tube 32 is sealed with the liquid outlet valve 4. The outer peripheral wall of the liquid taking tube 32 is sealed with the liquid outlet valve 4 to prevent the additive from flowing between the outer peripheral wall of the liquid taking tube 32 and the liquid outlet valve 4, and to prevent the additive from adhering to the outer peripheral wall of the liquid taking tube 32 and dripping as the liquid taking tube 32 is separated from the liquid outlet valve 4.

[0043] In order to facilitate the user to determine whether there is an additive in the container 2, Figure 5 As shown, a liquid level detection probe 33 is embedded in the body of the liquid collection tube 32, and a detection cavity 323 is provided at the front end of the liquid collection tube 32. The detection cavity 323 is connected with the inner cavity of the container 2 when the liquid collection tube 32 is in the liquid collection state, and the detection end of the liquid level detection probe 33 extends into the detection cavity 323. The user determines whether there is additive in the container 2 according to the detection result of the liquid level detection probe 33, so as to determine whether it is necessary to replace the additive with a new one, so as to avoid processing clothes when there is no or insufficient additive, resulting in inadequate processing of clothes. When the liquid collection tube 32 is in the initial state, such as Figure 6 As shown, the tube sleeve 31 is reset relative to the liquid collection tube 32 and is sealed with the outer peripheral wall of the liquid collection tube 32 to close the detection cavity 323, thereby preventing the additive in the detection cavity 323 from flowing between the outer wall of the liquid collection tube 32 and the inner wall of the tube sleeve 31, thereby preventing dripping due to the additive adhering to the periphery of the liquid collection tube 32.

[0044] In order to further increase the difficulty of the additive entering between the outer wall of the liquid taking pipe 32 and the liquid outlet valve 4, as Figure 3 As shown, the outer periphery of the liquid taking tube 32 is provided with a first sealing member 322 and a second sealing member 324. There are two first sealing members 322, which are located at the front and rear sides of the liquid taking port 321. When the liquid taking tube 32 is in the liquid taking state, as shown in FIG. Figure 7 As shown, the possibility of additives entering between the outer peripheral wall of the liquid collection pipe 32 and the liquid outlet valve 4 is further prevented by the sealing of the first sealing member 322, and the difficulty of additives entering between the outer peripheral wall of the liquid collection pipe 32 and the liquid outlet valve 4 is increased. When the liquid collection pipe 32 is in the initial state, the sealing of the first sealing member 322 prevents the additives in the liquid collection pipe 32 from entering between the outer peripheral wall of the liquid collection pipe 32 and the inner wall of the pipe sleeve 31 from the liquid collection port 321.

[0045] In order to further improve the sealing effect of the detection cavity 323 when the liquid extraction tube 32 is in the initial state, as shown in FIG. Figure 6As shown, two second seals 324 are also provided, and the two second seals 324 are distributed on both sides of the detection cavity 323 along the axial direction of the liquid collection tube 32. When the liquid collection tube 32 is in the initial state, the second seal 324 and the tube sleeve 31 are sealed to prevent the additives remaining in the detection cavity 323 from flowing to the outer peripheral wall of the liquid collection tube 32 and the tube sleeve 31. Alternatively, one second seal 324 is provided and is located at the front side of the detection cavity 323. The second seal 324 and the first seal 322 located at the rear side of the liquid collection port 321 are sealed at the front and rear sides of the detection cavity 323 to prevent the additives in the detection cavity 323 from overflowing to the outer peripheral wall of the liquid collection tube 32 along the axial direction of the liquid collection tube 32.

[0046] In another embodiment, if Figure 3 As shown, the liquid outlet valve 4 includes a valve body 41 and a valve core 42. The valve body 41 is provided with a valve cavity 411. The valve core 42 reciprocates in the valve cavity 411. The rear end of the valve body 41 is provided with an insertion port 414 for inserting the liquid extraction pipe 32 into the valve cavity 411. Figure 4 and Figure 5 As shown, the side wall of the valve body 41 is provided with a liquid inlet 412 and a detection port 413, the liquid inlet 412 is located between the insertion port 414 and the detection port 413, and the detection cavity 323 is located at the rear side of the liquid inlet 412, so that the detection result is the same as the actual liquid extraction result, avoiding the detection of additives while the liquid extraction result is no additives; when the liquid extraction tube 32 pushes open the liquid outlet valve 4, the rear end of the valve body 41 abuts against the front end of the pipe sleeve 31, and the rear end of the valve core 42 abuts against the front end of the liquid extraction tube 32, when the liquid extraction tube 32 is in the liquid extraction state, the liquid extraction port 321 is connected with the liquid inlet 412, and the detection cavity 323 and the detection port 413 at least partially overlap in the axial direction of the valve core 42, so that during the liquid extraction process of the liquid extraction tube 32, the additive enters the detection cavity 323 through the detection port 413, avoiding the deviation between the detection result and the actual result.

[0047] In order to improve the stability of the container 2 installed in the accommodating chamber 1, as shown in FIG. Figure 8As shown, the accommodating chamber 1 is provided with a push-lock 5 for locking the container 2. The push-lock 5 includes a pushing block 51 that reciprocates along the front-to-back direction on the accommodating chamber 1 and a clamping member 52 that is rotatably arranged on the pushing block 51. The clamping member 52 faces the container 2. The container 2 is provided with a limiting member 22, and the limiting member 22 is located at the rear end of the container 2. When the container 2 is installed, the container 2 is pushed from front to back so that the limiting member 22 abuts against the pushing block 51. The pushing block 51 moves along the front-to-back direction in the abutted state, driving the clamping member 52 to move backward. The accommodating chamber 1 is provided with a guide groove that drives the clamping member 52 to rotate. The clamping member 52 moves along the guide groove during the backward movement, so that the clamping member 52 rotates relative to the pushing block 51 until the limiting member 22 is engaged with the clamping member 52, so as to stably install the container 2 on the accommodating chamber 1, avoid the container 2 from detaching from the accommodating chamber 1 during use and affect the liquid extraction by the liquid extraction tube 32, and improve the stability of the installation of the container 2.

[0048] In this embodiment, if Figure 7 and Figure 8 As shown, the distance between the first sealing member 322 located at the rear side of the liquid taking port 321 and the liquid outlet inlet 412 is X. When the locked state of the container 2 is changed to the unlocked state where the container 2 can be directly taken out, the limit member 22 pushes the push block 51, so that the push block 51 moves from front to back, and the clamping member 52 rotates relative to the push block 51, so that the limit member 22 and the clamping member 52 are pushed apart. When the container 2 is in a state where it can be directly taken out relative to the accommodating chamber 1, the distance moved by the push block 51 is the stroke Y of the push block 51, that is, Y is the stroke of the container 2 from the locked state to the unlocked state, or from the unlocked state to the locked state, and X≥Y, ensuring that in the process of pushing the container 2 in the accommodating chamber 1 to unlock or lock the container 2, the first sealing member 322 is sealed at the rear side of the liquid outlet inlet 412 to prevent the additive from overflowing from the liquid outlet inlet 412 during the locking or unlocking process.

[0049] To improve the stability of the reciprocating motion of the valve core 42, as Fig. 9 As shown, a guide base 44 is provided at the front end of the valve body 41, and the front end of the valve core 42 passes through the guide base 44 and cooperates with the guide base 44. The rear end of the valve core 42 is sealed with the inner wall surface of the valve cavity 411, and the front end is supported by the guide base 44 to prevent the valve core 42 from deflecting during the reciprocating motion and affecting the sealing effect of the rear end of the valve core 42, thereby improving the stability of the reciprocating motion of the valve core 42.

[0050] To further improve the stability of the valve core 42, as Fig. 9As shown, a stop rib 421 is provided at the front of the valve core 42, and a stop step 441 is provided at the front of the guide base 44. When the valve core 42 is reset to make the liquid extraction tube 32 in the starting state, the stop rib 421 abuts against the stop step 441. The abutment between the stop rib 421 and the stop step 441 prevents the front end of the valve core 42 from entering the valve cavity 411, resulting in a lack of support for the front end of the valve core 42, thereby affecting the sealing effect between the rear end of the valve core 42 and the inner wall of the valve cavity 411.

[0051] In order to accelerate the return of the valve core 42 to close the liquid outlet 412, as shown in FIG. Fig. 9 As shown, an elastic reset member 43 is provided in the valve cavity 411 for driving the valve core 42 to reset. When the valve core 42 moves toward the front end of the valve body 41 to take liquid, the liquid taking tube 32 pushes the valve core 42, and the elastic reset member 43 is compressed, so that the elastic reset member 43 has a tendency to keep pushing the valve core 42 to reset. When the liquid taking tube 32 exits the valve cavity 411, the elastic reset member 43 drives the valve core 42 to reset in time, avoiding the liquid inlet 412 from being connected to the plug interface 414, thereby avoiding the additive from overflowing from the liquid inlet 412 and the plug interface 414 and being wasted.

[0052] In order to improve the stability of the installation of the elastic return member 43, a receiving chamber 442 for accommodating the elastic return member 43 is formed between the rear end of the guide base 44 and the inner wall of the valve chamber 411, and the front end of the elastic return member 43 extends into the receiving chamber 442 to prevent the front end of the elastic return member 43 from detaching from the guide base 44, thereby improving the stability of the elastic return member 43 after installation.

[0053] The present invention also provides a clothing processing device, including a machine body and an additive dispensing device arranged on the machine body. The additive dispensing device facilitates the use of additives, improves the convenience of use for users, and avoids waste caused by dripping of additives.

[0054] In addition to the above-mentioned preferred embodiments, the present invention also has other implementation modes. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
