[0027] This section will combine Figures 1 to 5 Embodiments of the present application are described in detail, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0028] In the description of the present application, it should be understood that if the terms "center", "middle", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like are used to indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, it is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. The features defined as "first" and "second" are used to distinguish the feature names, rather than having special meanings. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0029] 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, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0030] like Figure 1 As shown, an embodiment of the present application provides a washable multi-purpose pillow, which includes a shell assembly 101 and a pillow assembly. The shell assembly 101 and the pillow assembly can be installed as a whole and used as an ordinary pillow. At the same time, the shell assembly 101 and the pillow assembly can be disassembled, and the separated shell assembly 101 is combined with the second pillow 302 of the pillow assembly to be used as a water container for washing hair in a lying position. At this time, the first pillow 301 of the pillow assembly can be used alone as an ordinary pillow. In addition, the separated shell assembly 101 can be folded to reduce the occupied space and facilitate separate storage.

[0031] like Figure 2 As shown, in some examples, the shell component 101 is made of soft material. When the shell component 101 is stored separately, the user can fold the shell component 101 into any shape according to his or her own needs, so as to reduce the volume of the shell component 101 and provide convenience for storage.

[0032] Specifically, the shell component 101 is made of polypropylene material, which has large tensile strength, compressive strength and hardness, and has outstanding rigidity and bending fatigue resistance, which is conducive to the folding and storage process of the shell component 101. Moreover, the polypropylene material is odorless, tasteless and non-toxic. When the shell component 101 is used as a tool for washing hair in a lying position, it is safe and reliable. In addition, the polypropylene material is the lightest of the commonly used resins, which is also convenient for the handling and storage of the shell component 101. Alternatively, the shell component 101 is made of silicone material, which has high temperature resistance. When the shell component 101 is used as a tool for washing hair in a lying position, the hot water in the shell component 101 is prevented from damaging the structure of the shell component 101. Moreover, the silicone material has strong flexibility, which is conducive to the storage of the shell component 101. Alternatively, the shell component 101 is made of polypropylene material combined with silicone material, combining the performance of the two materials.

[0033] The shell component 101 is provided with a first accommodation space, and the first accommodation space is used to hold water for the user to wash his hair. Furthermore, the shell component 101 is provided with a water guide component. When the user needs to wash his hair in a lying position, the water is introduced along the water guide component and temporarily maintained in the first accommodation space; when the user finishes washing his hair, the water is guided out of the first accommodation space along the water guide component, which is convenient for the storage of the shell component 101, or for the shell component 101 to be reassembled into one with the pillow component.

[0034] Meanwhile, the water guide assembly includes a liquid channel 103, and water is introduced into or out of the first accommodation space along the liquid channel 103. It is understandable that the liquid channel 103 is connected to the first accommodation space on the one hand, and is connected to the external space on the other hand. When water needs to be introduced into the first accommodation space, an external water supply pipe and other structures are connected to the liquid channel 103.

[0035] In some examples, the housing assembly 101 is provided with a receiving groove 102, the receiving groove 102 is located in the middle of the housing assembly 101, and the housing assembly 101 forms a folded edge at the edge of the receiving groove 102. It can be understood that the first receiving space is surrounded by the receiving groove 102.

[0036] Furthermore, the accommodating tank 102 is connected to the liquid channel 103, and the water introduced along the liquid channel 103 can reach the accommodating tank 102, that is, reach the first accommodating space; the water discharged along the liquid channel 103 can be discharged from the accommodating tank 102, that is, discharged from the first accommodating space.

[0037] Specifically, the liquid channel 103 is disposed at the bottom of the receiving tank 102. After the user finishes washing their hair, the liquid channel 103 is opened, and water can be discharged from the receiving tank 102 along the liquid channel 103 by gravity. This prevents water from remaining in the receiving tank 102 and causing obstacles to the storage of the housing assembly 101 or the reassembly of the housing assembly 101 and the pillow assembly.

[0038] In some examples, the housing assembly 101 includes a supporting structure 104, and when the user washes their hair in a lying position, the user's head or neck fits against the top of the supporting structure 104. A supporting surface with a certain area is provided on the top of the supporting structure 104, and the supporting surface forms a concave shape in a natural state, thereby increasing the contact area between the user's head and neck and the housing assembly 101, providing support for the user's head or neck, and improving the user's comfort. It is understandable that when the user uses the housing assembly 101 to wash their hair in a lying position, the user's head or neck is at the edge of the housing assembly 101, that is, the edge of the accommodating groove 102. Therefore, the supporting structure 104 is arranged at the edge of the accommodating groove 102.

[0039] In some examples, the side wall of the accommodating groove 102 includes a main body defining portion 106 and an inner recess 105, wherein the main body defining portion 106 defines the main part of the first accommodating space, and the inner recess 105 extends into the first accommodating space. On the one hand, the main body defining portion 106 and the inner recess 105 together enclose the first accommodating space; on the other hand, the inner recess 105 increases the width of the folded edge of the housing assembly 101 at the location, thereby defining a supporting structure 104 on the housing assembly 101.

[0040] It is understandable that the supporting structure 104 is integrally formed with the shell assembly 101, and the supporting structure 104 is also made of soft material. When the user's head or neck is on top of the supporting structure 104, under the action of the gravity of the user's head and neck, the supporting structure 104 will further produce a depression, and the shape of the depression is completely in accordance with the shape of the user's head or neck, thereby increasing the contact area between the user's head, neck and the supporting structure 104, and improving the comfort level.

[0041] In some examples, the housing assembly 101 is provided with a hollow water guide hole, the hollow inner cavity of the water guide hole forms a liquid channel 103, and the water guide hole is located at the bottom of the accommodating groove 102. It can be understood that one end of the water guide hole is connected to the first accommodating space, and the other end of the water guide hole is connected to the external space, and water enters the first accommodating space along the water guide hole and is discharged from the first accommodating space along the water guide hole.

[0042] In some examples, the water guide assembly includes a watertight cover 201, which can cover the water guide hole and is detachably connected to the water guide hole. When the user does not need to wash their hair in a lying position, the watertight cover 201 is continuously connected to the water guide hole to prevent the watertight cover 201 from being accidentally lost, thereby affecting the user's lying position hair washing process.

[0043] Furthermore, when the user washes his hair in a lying position, water needs to enter the first accommodation space along the water guide hole. At this time, the watertight cover 201 is removed and the water guide hole is opened to facilitate the introduction of water. When a sufficient amount of water has been introduced into the first accommodation space, the water needs to be temporarily maintained in the first accommodation space. At this time, the watertight cover 201 is installed at the position of the water guide hole to cut off the water guide hole. The watertight cover 201 and the water guide hole are well sealed to prevent water from flowing out along the water guide hole. When the user finishes washing his hair, the water needs to be guided out of the first accommodation space. At this time, the watertight cover 201 is removed and the water guide hole is opened again. The water will flow out along the water guide hole under the influence of its own gravity.

[0044] Specifically, the watertight cover 201 is provided with a handle 204, and the user can hold the watertight cover 201 through the handle 204, which facilitates the installation and removal process of the watertight cover 201. Among them, a boss is provided at the edge of the water guide hole, and the water guide hole is detachably connected to the watertight cover 201 through the boss. Since the boss is provided at the edge of the water guide hole, and the water guide hole is a hollow structure, the boss is also a hollow cylindrical structure.

[0045] like Figure 3 As shown, in the first embodiment, the watertight cover 201 can be inserted into the boss to achieve a detachable connection. The inner wall of the boss is provided with a first internal thread, and the outer wall of the watertight cover 201 is provided with a first external thread 202, and the first internal thread and the first external thread 202 are meshed with each other to form a threaded connection.

[0046] To ensure that the thread has enough turns, the boss has a certain height. According to the user's usage habits, the boss can extend toward the first accommodating space or toward the outside of the housing assembly 101 .

[0047] In addition, one end of the boss faces the first accommodation space, and the other end faces the outside of the housing assembly 101. According to the user's usage habits, the watertight cover 201 is inserted from the boss toward one end of the first accommodation space, or from the boss toward one end outside the housing assembly 101, thereby forming a detachable connection.

[0048] like Figure 4 As shown, in the second embodiment, the watertight cover 201 is hollow, one end is open, and the other end is sealed. The watertight cover 201 is sleeved on the boss to achieve a detachable connection. The outer wall of the boss is provided with a second external thread, and the inner wall of the watertight cover 201 is provided with a second internal thread 203, and the second internal thread 203 is meshed with the second external thread to form a threaded connection.

[0049] Similarly, the boss may extend toward the first accommodating space or toward the outside of the housing assembly 101 , with one end of the boss facing the first accommodating space and the other end facing the outside of the housing assembly 101 .

[0050] It is understandable that, in order to ensure that the threaded connection has a sufficient number of turns, the watertight cover 201 in the second embodiment needs to have a certain height, and the boss needs to leave space for the installation of the watertight cover 201. Therefore, when the boss extends toward the first accommodating space, the watertight cover 201 needs to be connected from the boss toward one end of the first accommodating space; when the boss extends toward the outside of the housing assembly 101, the watertight cover 201 needs to be connected from the boss toward one end of the housing assembly 101.

[0051] In some examples, the housing assembly 101 includes an airbag, which forms the main structure of the housing assembly 101, and the first accommodation space and the water guide assembly are both arranged in the airbag. When the airbag is inflated, the accommodation groove 102 and the supporting structure 104 are formed. When the housing assembly 101 is stored alone, the volume of the housing assembly 101 can be reduced by simply extracting the gas in the airbag.

[0052] like Figure 5 and Figure 6 As shown, in some examples, the pillow assembly is detachably connected to the housing assembly 101, and the pillow assembly includes a first pillow 301 and a second pillow 302. When there is no water in the first accommodation space of the housing assembly 101, the first pillow 301 can be placed in the first accommodation space, and the second pillow is provided with a second accommodation space, and the housing assembly 101 can be placed in the second accommodation space, so that the pillow assembly and the housing assembly 101 form a whole. In actual implementation, the upper end of the first pillow 301 can be provided with a decorative part protruding upward, and the decorative part is integrally formed with the upper end surface of the first pillow 301, or the decorative part is sutured and connected to the upper end surface of the first pillow 301. Among them, the decorative part can be an animal shape to increase the aesthetics and interest of the first pillow 301. When the user needs to wash his hair in a lying position, the first pillow 301 is disassembled, and the whole formed by the second pillow 302 and the housing assembly 101 is used as a water container, and the disassembled first pillow 301 can be used alone. When the user does not need to use the shell assembly 101, the shell assembly 101 is disassembled and stored, and the first pillow 301 is reinstalled on the second pillow 302. The whole formed by the first pillow 301 and the second pillow 302 is used as a common pillow. It is understandable that the first pillow 301 can also be used alone at this time.

[0053] In some examples, the second pillow 302 is provided with a mounting groove 303, and the second pillow 302 naturally forms a wall of the mounting groove 303 at the edge of the mounting groove 303, and the wall of the mounting groove 303 supports the bottom of the folded edge of the housing assembly 101 to prevent the housing assembly 101 from deforming when the user washes his hair in a lying position. The top shape of the wall of the mounting groove 303 corresponds to the bottom shape of the folded edge of the housing assembly 101, so that the two fit together from top to bottom. It can be understood that the mounting groove 303 encloses a second accommodation space.

[0054] Furthermore, the second pillow 302 is provided with an installation channel 304, and the installation channel 304 leaves space for external water supply pipes and other structures to access the liquid channel 103, and the installation channel 304 and the liquid channel 103 are connected to each other in a docking manner.

[0055] In some examples, a support structure 305 is provided at the edge of the second pillow 302. When the second pillow 302 is assembled and installed with the shell assembly 101, the support structure 305 supports the supporting structure 104 at the bottom of the supporting structure 104. The support structure 305 is located at the edge of the mounting groove 303 and is formed by the surrounding wall of the mounting groove 303. The bottom shape of the support structure 305 corresponds to the top shape of the supporting structure 104, so that the two can fit each other up and down.

[0056] In some examples, the first pillow 301 and the second pillow 302 both include a cover and a filler, and the cover is placed on the outside of the filler to prevent dirt from appearing on the surface of the filler.

[0057] Specifically, the user can manually adjust the position and shape of the filling in the support structure 305 of the second pillow 302 according to needs, thereby changing the support effect of the support structure 305 and ensuring that the supporting structure 104 can bring a more comfortable touch when washing hair in a lying position.

[0058] Furthermore, the filler is made of materials such as polyester fiber, polyurethane, latex, etc. Polyester fiber, polyurethane and latex are all non-toxic and harmless soft materials, which improve the comfort level of users.

[0059] During the use of the washable multi-purpose pillow, when the shell component 101 and the pillow component are installed as one, the washable multi-purpose pillow can be used as an ordinary pillow; when the first pillow 301 is disassembled, the first pillow 301 can still be used as an ordinary pillow, and the shell component 101 combined with the second pillow 302 can be used for lying hair washing. Among them, the watertight cover 201 is disassembled, and the water for washing hair is introduced into the first accommodation space along the water guide hole, and then the watertight cover 201 is installed to maintain the water for washing hair in the first accommodation space. The user completes the hair washing process with the supporting structure 104 supporting the head or neck. After washing hair, the watertight cover 201 is disassembled again, and the water for washing hair is guided out of the first accommodation space. In addition, when the shell component 101 is stored alone, the soft shell component 101 can be folded to reduce the volume. At this time, the first pillow 301 can be installed on the second pillow 302 for use, and the first pillow 301 can also be used alone.
