Therefore, the water tank assembly in the clothing care device provided by the embodiment of the present application has good sealing performance.

[0008] In a possible implementation, in the clothing care device provided by the present application, the shape of the concave-convex structure matches the shape of the end of the flow channel facing the water containing chamber.

[0009] In this way, the concave-convex structure can more closely abut against the end of the flow channel facing the water containing chamber to seal the gap therebetween.

[0010] In one possible implementation, the clothing care device provided by the present application has a concave-convex structure including a first sealing surface, a second sealing surface and a third sealing surface. The first sealing surface, the second sealing surface and the third sealing surface are all annular surfaces and are connected in sequence from the circumferential inner side to the circumferential side of the valve stem. The first sealing surface, the second sealing surface and the third sealing surface have different angles relative to the moving direction of the valve stem.

[0011] In this way, by providing the first sealing surface, the second sealing surface and the third sealing surface to jointly form a concave-convex structure, it is possible to avoid the situation where a single sealing surface is not able to fit well with the end of the flow channel facing the water containing chamber due to insufficient flatness of the sealing surface, thereby effectively improving the sealing performance of the valve unit.

The first limit part and the second limit part can jointly limit the movement distance of the valve stem and the sealing valve core relative to the flow channel to prevent the valve stem and the sealing valve core from completely separating from the flow channel.

[0021] In a possible implementation, in the clothing care device provided in the present application, the first limiting portion is slidably connected to the flow channel.

[0022] In this way, during the movement of the valve stem and the sealing valve core, the first limiting portion can guide the stem body and the sealing valve core to always move along the axial direction of the stem body.

[0023] In a possible implementation, in the clothing care device provided by the present application, the first limiting portion is provided with a first channel, and the second limiting portion is provided with a second channel.

[0028] In this way, the seal can cut off the path of liquid flowing outward from the gap between the valve seat body and the through hole and along the gap between the first threaded connection part and the second threaded connection part, thereby effectively sealing the gap between the valve seat body and the through hole.

The embodiments of the present application are described in detail below in conjunction with the drawings.

[0051] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, or it can be an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

[0053] The terms "first", "second", "third" (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0054] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or display comprising a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or display.

[0055] In the related art, a clothing care machine may include a steam generating device, a water tank and a care box. The care box has a care chamber, and the clothing is hung in the care chamber. The steam generated by the steam generating device is passed into the care chamber, and then the clothing is softened by high-temperature steam to smooth out the wrinkles on the clothing, thereby realizing the wrinkle removal function of the clothing. The water tank can store water and provide it to the steam generating device when necessary. The water tank mainly includes a box body and a water valve. The water valve includes a valve body and a valve core. The valve body has a flow channel. The valve core has a sealing surface. The sealing surface cooperates with the valve body to close the flow channel. The valve core is pushed open by a push rod to open the flow channel, so that the water tank replenishes water for the steam generating device. However, when the flatness of the sealing surface of the valve core is not enough, the valve core cannot cooperate with the valve body to seal well, so that the water valve has insufficient sealing.

[0056] Based on the above problems, an embodiment of the present application provides a clothing care device, which is provided with a water tank assembly, and the sealing part has a concave-convex structure on the side facing the flow channel, which is sealed and abutted with the end of the flow channel facing the water containing chamber through the concave-convex structure, thereby avoiding the reduction in sealing caused by insufficient flatness of a single sealing surface.

[0057] The specific implementation of the clothing care device provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0058] Reference Figures 1 to 5 As shown, the clothing care device provided by the present application includes a water tank assembly 10, the water tank assembly 10 includes a water tank 100 and a valve unit 200, the water tank 100 has a water containing chamber 110, the valve unit 200 includes a valve seat 210, a valve stem 220 and a sealing valve core 230, the valve seat 210 is connected to the water tank 100, the valve seat 210 has a flow channel 211 connected to the water containing chamber 110, the valve stem 220 is located in the flow channel 211, and is constructed to drive the sealing valve core 230 to move relative to the flow channel 211, and the sealing valve core 230 has a sealing portion 231 for closing the flow channel 211.

[0059] The sealing portion 231 has a concavo-convex structure 2311 on one side facing the flow channel 211 . When the valve unit 200 is closed, the end of the flow channel 211 facing the water containing chamber 110 is sealed against the concavo-convex structure 2311 .

[0060] It should be noted that the clothing care device can also include a device body 20 and a steam generating component. The device body 20 has a clothing care cavity 201. Clothes are placed in the clothing care cavity 201 and softened and ironed by the high-temperature steam generated by the steam generating component. The water tank component 10 can be used to supply water to the steam generating component.

[0061] In the present application, the water chamber 110 of the water tank 100 is used to store liquid, and the valve unit 200 is used to control the on / off state of the inside and outside of the water chamber 110, so that the liquid in the water chamber 110 can be replenished to the steam generating component of the clothing care equipment, etc.

[0062] Specifically, the valve unit 200 may include a valve seat 210, a valve stem 220 and a sealing valve core 230. The valve seat 210 is fixedly connected to the water tank 100. The liquid in the water containing chamber 110 can flow to the outside of the water containing chamber 110 through the flow channel 211 of the valve seat 210, or the liquid outside the water containing chamber 110 can enter the water containing chamber 110 through the flow channel 211. The sealing valve core 230 can move relative to the flow channel 211 driven by the valve stem 220, so that the sealing valve core 230 opens the flow channel 211 or closes the flow channel 211. That is, when the concave-convex structure 2311 is in sealing contact with one end of the flow channel 211 facing the water containing chamber 110, the sealing valve core 230 closes the flow channel 211. When the concave-convex structure 2311 is spaced from the end of the flow channel 211 facing the water containing chamber 110, the sealing valve core 230 opens the flow channel 211.

[0063] In order to improve the sealing performance when the valve unit 200 is closed, the concave-convex structure 2311 may include three parts, namely a first sealing surface 2311a, a second sealing surface 2311b and a third sealing surface 2311c. The first sealing surface 2311a and the third sealing surface 2311c are inclined relative to the moving direction of the sealing valve core 230, and the inclination directions of the two are opposite, that is, the concave-convex structure 2311 can be a recessed part or a raised part.

[0064] For example, the side of the first sealing surface 2311a away from the valve stem 220 is inclined toward the water containing chamber 110 relative to the side close to the valve stem 220, while the side of the third sealing surface 2311c close to the valve stem 220 is inclined toward the water containing chamber 110 relative to the side away from the valve stem 220, and the second sealing surface 2311b can be arranged perpendicularly relative to the moving direction of the sealing valve core 230. In this way, the recessed portion formed by the first sealing surface 2311a, the second sealing surface 2311b and the third sealing surface 2311c can wrap the end of the flow channel 211 facing the water containing chamber 110, so as to avoid the situation where a single sealing surface is used and the sealing surface is not flat enough to fit and abut with the end of the flow channel 211 facing the water containing chamber 110.

[0065] For another example, the side of the first sealing surface 2311a close to the valve stem 220 is inclined toward the water containing chamber 110 relative to the side away from the valve stem 220, and the side of the third sealing surface 2311c away from the valve stem 220 is inclined toward the water containing chamber 110 relative to the side close to the valve stem 220. The second sealing surface 2311b can be arranged perpendicularly relative to the moving direction of the sealing valve core 230. The raised portion formed by the first sealing surface 2311a, the second sealing surface 2311b and the third sealing surface 2311c can be wrapped by the end of the flow channel 211 facing the water containing chamber 110, thereby avoiding the situation where a single sealing surface is used and the sealing surface is not flat enough to cooperate and abut with the end of the flow channel 211 facing the water containing chamber 110. As a result, the valve unit 200 has better sealing performance, thereby improving the sealing performance of the water tank assembly 10.

[0066] The clothing care device provided by the embodiment of the present application includes a water tank assembly 10, the water tank assembly 10 includes a water tank 100 and a valve unit 200, the water tank 100 includes a water containing chamber 110, the valve unit 200 includes a valve seat 210, a valve stem 220 and a sealing valve core 230, the valve seat 210 includes a flow channel 211, the sealing valve core 230 includes a sealing portion 231, and the sealing portion 231 includes a concave-convex structure 2311. The water containing chamber 110 is provided for storing liquid, and the flow channel 211 is used to communicate with the water containing chamber 110. 0 and the outside of the water-containing chamber 110, by providing a valve stem 220 to drive the sealing valve core 230 to move, so that the sealing valve core 230 opens or closes the flow channel 211, and by providing a concave-convex structure 2311 to cooperate with and abut the end of the flow channel 211 facing the water-containing chamber 110, so as to effectively seal the flow channel 211, thereby effectively avoiding the problem that when a single sealing surface is used, the sealing surface is not flat enough, and cannot cooperate with and abut the end of the flow channel 211 facing the water-containing chamber 110. Therefore, the water tank assembly 10 in the clothing care device provided in the embodiment of the present application has good sealing performance.

[0067] In a possible implementation, the shape of the concave-convex structure 2311 matches the shape of the end of the flow channel 211 facing the water containing chamber 110 .

[0068] In this way, the concave-convex structure 2311 can be more closely abutted against the end of the flow channel 211 facing the water containing chamber 110 to seal the gap therebetween.

[0069] Reference Figure 5 and Figure 6As shown, in a specific implementation, the concave-convex structure 2311 may include a first sealing surface 2311a, a second sealing surface 2311b and a third sealing surface 2311c. The first sealing surface 2311a, the second sealing surface 2311b and the third sealing surface 2311c are all annular surfaces, and are connected in sequence from the circumferential inner side to the circumferential side of the valve stem 220. The first sealing surface 2311a, the second sealing surface 2311b and the third sealing surface 2311c have different angles relative to the moving direction of the valve stem 220.

[0070] In this way, the first sealing surface 2311a, the second sealing surface 2311b and the third sealing surface 2311c are provided to jointly form the concave-convex structure 2311. For example, the first sealing surface 2311a, the second sealing surface 2311b and the third sealing surface 2311c can jointly form a recessed portion, or the first sealing surface 2311a, the second sealing surface 2311b and the third sealing surface 2311c can jointly form a raised portion. This can avoid the situation where a single sealing surface is not flat enough to fit well with the end of the flow channel 211 facing the water containing chamber 110, thereby effectively improving the sealing performance of the valve unit 200.

[0071] Reference Figures 4 to 6 As shown, in order to make the end of the flow channel 211 facing the sealing valve core 230 better fit and abut against the sealing surface, in a possible implementation, the end of the flow channel 211 facing the sealing valve core 230 has a mating surface 2111, and the mating surface 2111 includes a first mating surface 2111, a second mating surface 2111 and a third mating surface 2111, the first sealing surface 2311a fits and abuts against the first mating surface 2111, the second sealing surface 2311b fits and abuts against the second mating surface 2111, and the third sealing surface 2311c fits and abuts against the third mating surface 2111.

[0072] It can be understood that the inclination direction of the first mating surface 2111 is consistent with the inclination direction of the first sealing surface 2311a so that the two fit together, the inclination mode of the third mating surface 2111 is consistent with the inclination direction of the third sealing surface 2311c so that the two fit together, and the second mating surface 2111 fits with the second sealing surface 2311b. In this way, the gap between the end of the flow channel 211 toward the sealing valve core 230 and the sealing valve core 230 can be effectively sealed through the cooperation of the first sealing surface 2311a with the first mating surface 2111, the cooperation of the second sealing surface 2311b with the second mating surface 2111, and the cooperation of the third sealing surface 2311c with the third mating surface 2111, thereby improving the sealing of the valve unit 200 and avoiding liquid leakage.

[0073] In some embodiments, the second sealing surface 2311b is arranged parallel to the radial direction of the valve stem 220. That is, the valve stem 220 moves along its own axial direction relative to the flow channel 211, thereby driving the sealing valve core 230 to move along the axial direction of the valve stem 220, the first sealing surface 2311a and the third sealing surface 2311c are arranged obliquely relative to the axial direction of the valve stem 220, and the second sealing surface 2311b is arranged parallel to the radial direction of the valve stem 220, so that the first sealing surface 2311a, the second sealing surface 2311b and the third sealing surface 2311c can form a concave-convex structure 2311 together, thereby avoiding the first sealing surface 2311a, the second sealing surface 2311b and the third sealing surface 2311c from not being able to fit well with the mating surface 2111 due to insufficient flatness of one of the first sealing surface 2311a, the second sealing surface 2311b and the third sealing surface 2311c.

[0074] The side of the first sealing surface 2311a away from the valve stem 220 is inclined toward the water containing chamber 110 relative to the side close to the valve stem 220. The first sealing surface 2311a, the second sealing surface 2311b and the third sealing surface 2311c together form a recessed portion, so that the end of the flow channel 211 facing the sealing valve core 230 abuts against the recessed portion.

[0075] Reference Figure 5 and Figure 6 As shown, in a possible implementation, the sealing valve core 230 further includes a connecting portion 232 , the sealing portion 231 is connected to the outer peripheral side of the connecting portion 232 , and the valve stem 220 is inserted into the connecting portion 232 .

[0076] In this way, an annular sealing portion 231 can be formed on the outer peripheral side of the connecting portion 232, and then an annular concave-convex structure 2311 can be formed, so as to fully abut against the end of the flow channel 211 toward the sealing valve core 230 to prevent liquid from leaking from the gap between the sealing portion 231 and the end of the flow channel 211 toward the sealing valve core 230.

[0077] Reference Figure 5 As shown, in a specific implementation, the valve stem 220 includes a rod body 221 and a first limiting portion 222, the first limiting portion 222 and the sealing valve core 230 are connected at both ends of the rod body 221, the valve seat 210 includes a valve seat body 212 and a second limiting portion 213 that are connected to each other, the valve seat body 212 has a flow channel 211, the second limiting portion 213 is located between the sealing valve core 230 and the first limiting portion 222, and the rod body 221 is inserted in the second limiting portion 213.

[0078] In this way, the valve stem 220 can drive the sealing valve core 230 to move through the rod body 221, so that the sealing part 231 opens the flow channel 211 or closes the flow channel 211. The first limiting part 222 and the second limiting part 213 can jointly limit the movement distance of the valve stem 220 and the sealing valve core 230 relative to the flow channel 211 to prevent the valve stem 220 and the sealing valve core 230 from completely separating from the flow channel 211.

[0079] In a possible implementation, the first limit portion 222 is slidably connected to the flow channel 211. In this way, when the valve stem 220 is subjected to an external force of lifting, the sealing valve core 230 can be prevented from shaking due to the inconsistency between the direction of the external force and the axial direction of the valve stem 220, and when the external force of lifting disappears, the sealing valve core 230 can be prevented from shaking during the process of resetting the valve stem 220 and the sealing valve core 230. During the movement of the valve stem 220 and the sealing valve core 230, the first limit portion 222 can guide the rod body 221 and the sealing valve core 230 to always move along the axial direction of the rod body 221.

[0080] For example, there is a small gap between the outer wall of the first limiting portion 222 and the inner wall of the flow channel 211 so that the two are slidably connected, or the first limiting portion 222 and the flow channel 211 can be provided with guide structures such as sliding grooves and guide rails.

[0081] Reference Figure 5 As shown, in some embodiments, the first limiting portion 222 is provided with a first channel 2221, and the second limiting portion 213 is provided with a second channel 2131. The first channel 2221 is connected to the opposite sides of the first limiting portion 222, and the second channel 2131 is connected to the opposite sides of the second limiting portion 213.

[0082] In this way, the liquid can flow on opposite sides of the first limiting portion 222 through the first channel 2221, and the liquid can flow on opposite sides of the second limiting portion 213 through the second channel 2131, and the flow channel 211 will not be blocked by the first limiting portion 222 and the second limiting portion 213.

[0083] Reference Figure 5 As shown, in a possible implementation, the valve seat 210 also includes a first threaded connection portion 214, which is connected to the outer peripheral side of the valve seat body 212, and the first threaded connection portion 214 has an internal thread. The water tank 100 has a second threaded connection portion 120, and the second threaded connection portion 120 has a through hole and an external thread. The valve seat body 212 is inserted into the through hole, and the internal thread and the external thread are matched and connected.

[0084] In this way, the valve seat 210 can be connected by the threaded fit between the first threaded portion and the second threaded portion, and then the valve seat 210 can be installed on the water tank 100, so that the valve unit 200 can be installed on the water tank 100 as a whole.

[0085] Reference Figure 5 As shown, since the valve seat body 212 and the through hole cannot be completely fitted, in order to prevent liquid from leaking from the gap between the valve seat body 212 and the through hole, in a possible implementation, the valve unit 200 may also include a sealing member 240, which is disposed between an end of the first threaded connection portion 214 away from the water containing chamber 110 and an end of the second threaded connection portion 120 away from the water containing chamber 110, and is constructed to seal the gap between the valve seat body 212 and the through hole.

[0086] In this way, since there is an annular space between the inner wall of the first threaded connection part 214 and the outer wall of the valve seat body 212, the second threaded connection part 120 is located in the annular space between the first threaded connection part 214 and the valve seat body 212, and the sealing member 240 can be arranged at the end of the annular space away from the water containing chamber 110, that is, the sealing member 240 can abut between the end of the first threaded connection part 214 away from the water containing chamber 110 and the end of the second threaded connection part 120 away from the water containing chamber 110. In this way, the sealing member 240 can cut off the path of the liquid flowing outward from the gap between the valve seat body 212 and the through hole and along the gap between the first threaded connection part 214 and the second threaded connection part 120, thereby effectively sealing the gap between the valve seat body 212 and the through hole.

[0087] Reference Figure 2 , Figure 3 and Figure 7 As shown, in a possible implementation, the water tank assembly 10 further includes a handle unit 300 , the handle unit 300 includes a handle piece 310 and a connector 320 , and the water tank 100 has a storage groove 130 on the side facing away from the valve unit 200 , and the handle piece 310 is stored in the storage groove 130 .

[0088] Hinge grooves 131 are provided at both ends of the storage groove 130 in the extension direction. The handle piece 310 is provided with an installation cavity 311 and a hinge hole 312 which are interconnected. The hinge hole 312 is located in the installation cavity 311. One end of the connecting piece 320 is hinged to the hinge groove 131, and the other end of the connecting piece 320 is hinged to the hinge hole 312.

[0089] In this way, when the handle 310 is not needed, the handle 310 can be stored in the storage groove 130, and when the handle 310 is needed, the handle 310 can be easily stood up to facilitate the user to lift the water tank 100.

[0090] The handle 310 can be in contact with the groove wall of the receiving groove 130 by interference fit, so as to fix the handle 310 in the receiving groove 130, thereby preventing the handle 310 from shaking at will.

[0091] Reference Figure 7 As shown, in a possible implementation, the handle unit 300 further includes an elastic member 330 , which is located in the mounting cavity 311 , abuts between the handle member 310 and the connecting member 320 , and is constructed to abut the handle member 310 in the storage groove 130 .

[0092] It is understandable that after long-term use, the handle piece 310 and the storage groove 130 will be worn due to the mutual friction between the two, and the interference fit between the two will gradually decrease, so that the handle piece 310 can no longer be fixedly stored in the storage groove 130 by interference fit. In the above-mentioned setting, since the handle unit 300 is also provided with an elastic member 330, the elastic member 330 abuts between the handle piece 310 and the connecting member 320, so that the elastic member 330 can provide elastic force to the handle piece 310, and the direction of the elastic force points to the side wall of the storage groove 130, so that the handle piece 310 can be abutted against the storage groove 130 to prevent the handle piece 310 from shaking.
