[0052] The following is an explanation of the implementation of the present invention by means of specific specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Although the description of the present invention will be introduced in conjunction with the preferred embodiment, this does not mean that the features of this utility model are limited to this implementation. On the contrary, the purpose of introducing the utility model in conjunction with the implementation is to cover other options or modifications that may be extended based on the claims of the present invention. In order to provide an in-depth understanding of the present invention, the following description will contain many specific details. The present invention can also be implemented without using these details. In addition, in order to avoid confusion or blurring the focus of the present invention, some specific details will be omitted in the description. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0053] It should be noted that in this specification, similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0054] In the description of this embodiment, it should be noted that the terms "upper", "lower", "inner", "bottom", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the utility model.

[0055] The terms “first”, “second”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0056] In the description of this embodiment, it should be noted that, unless otherwise specified or limited, the terms "disposed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this embodiment based on specific circumstances.

[0057] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0058] With reference to Figures 1 to 15, the present application provides a pool body 1, and the present application takes the pool body 1 as an example of a bathtub. The bathtub includes: an outer frame 10 and an inner liner (pool body to be described later). The outer frame 10 is a hard material, and the inner liner is a soft material. The outer frame 10 includes a hard pool body accommodating cavity 11, which is made of a hard material and is used to accommodate the soft pool body 20 to be described later. Figure 2 shows that the shape of the hard pool body accommodating cavity 11 is square, but the present application does not limit the shape of the hard pool body accommodating cavity 11, as long as it can accommodate the soft pool body 20 to be described later. For example, in some possible embodiments, the shape of the hard pool body accommodating cavity 11 is circular, pentagonal, hexagonal, octagonal, etc.

[0059] The hard pool body accommodating cavity 11 extends in the longitudinal direction (as shown in the Z direction in Figures 1, 2 and 4), and the hard pool body accommodating cavity 11 is surrounded by multiple fences that are detachably connected along the circumferential direction and / or longitudinal direction, and the circumference surrounds the longitudinal direction. That is, multiple fences are detachably connected along the circumferential direction to enclose the hard pool body accommodating cavity 11; or, multiple fences are detachably connected along the longitudinal direction to enclose the hard pool body accommodating cavity 11; or, multiple fences are detachably connected along the circumferential direction and detachably connected along the longitudinal direction to enclose the hard pool body accommodating cavity 11. This application takes multiple fences detachably connected along the circumferential direction and detachably connected along the longitudinal direction to enclose the hard pool body accommodating cavity 11 as an example, which will be described in detail later.

[0060] The above-mentioned inner liner is a soft pool body 20 with an open mouth. The soft pool body 20 includes a water holding cavity 21 (for storing water) and a connecting portion 22. The water holding cavity 21 extends longitudinally, and the longitudinal top of the water holding cavity 21 has an open mouth. The connecting portion 22 extends outward from the longitudinal top of the water holding cavity 21. That is, the inner wall of the bathtub is made of a single layer of soft material. The water holding cavity 21 of the soft pool body 20 is accommodated in the hard pool body holding cavity 11, and the connecting portion 22 of the soft pool body 20 is detachably connected to the longitudinal top of the hard pool body holding cavity 11. Figures 1 and 4 show that the shape of the water holding cavity 21 is a quadrilateral, but the present application does not limit the shape of the water holding cavity 21. It only needs to be able to be accommodated in the hard pool body holding cavity 11. For example, in some possible embodiments, the shape of the water holding cavity 21 is circular, pentagonal, hexagonal, octagonal, etc.

[0061] Thus, the present application provides a detachable bathtub comprising a rigid outer frame 10 and a flexible inner liner. The rigid outer frame 10 is formed by a plurality of detachably connected railings. After the water-holding cavity 21 of the flexible body 20, serving as the flexible inner liner, is accommodated within the rigid body-holding cavity 11 of the rigid outer frame 10, the flexible body 20 is detachably connected to the longitudinal top of the rigid body-holding cavity 11 via a connecting portion 22. This arrangement facilitates disassembly and storage of the bathtub, reduces floor space, and facilitates transportation.

[0062] Furthermore, since the detachable bathtub utilizes a hard outer frame 10 and a soft inner liner, after the soft body 20, which serves as the soft inner liner, is filled with water, the hard outer frame 10 provides support. For example, the longitudinal top of the hard body chamber 11 passes through the connection portion 22 supporting the soft body 20, thereby supporting the water chamber of the soft body 20.

[0063] For example, the aforementioned railing is made of plastic wood or wood. Currently, bathtub frames 10 on the market are made of acrylic, airbags, metal frames, and concrete structures. The bathtub frame 10 of this application uses plastic wood railings, replacing traditional acrylic, airbags, and metal frames. This improves the overall appearance of the bathtub.

[0064] For example, the material of the soft pool body 20 is PVC or PVC with mesh. The PVC with mesh and PVC leather material are selected to meet the water pressure bearing requirements.

[0065] In some possible embodiments, referring to Figure 2 , both ends of the rigid body cavity 11 are open longitudinally. Once the water chamber 21 is contained within the rigid body cavity 11 of the rigid outer frame 10, the ground supports the longitudinal bottom of the water chamber 21 when the bathtub is placed on the ground. In other words, the rigid body cavity 11, enclosed by multiple enclosures, and the ground jointly support the water chamber 21 of the soft body 20. This eliminates the need for additional structural support for the water chamber 21, saving costs.

[0066] As described above, the present application uses as an example a plurality of fences that are detachably connected along the circumferential direction and detachably connected along the longitudinal direction to enclose a hard pool body accommodating cavity 11 .

[0067] In some possible embodiments, referring to Figures 2 and 5 to 9, the plurality of fences include: a first fence 12, a second fence 13, a third fence 14, and a fourth fence 15 distributed in sequence along the circumferential direction. The first fence 12 and the third fence 14 extend in the first direction (shown in the X direction in Figures 2 and 8) and are spaced apart in the second direction (shown in the Y direction in Figures 2 and 8), and the first direction and the second direction are perpendicular to the longitudinal direction. The second fence 13 and the fourth fence 15 extend in the second direction and are spaced apart in the first direction. Exemplarily, the above-mentioned first direction, second direction, and longitudinal direction are perpendicular to each other. Thus, the plurality of fences enclose a quadrilateral hard pool body accommodating cavity 11.

[0068] Along the first direction, one longitudinal end of the first fence 12 and one longitudinal end of the second fence 13 are detachably connected via a first corner beam 16, and the other longitudinal end of the first fence 12 and one longitudinal end of the fourth fence 15 are detachably connected via a second corner beam 17, and the first corner beam 16 and the second corner beam 17 extend longitudinally respectively; along the first direction, one longitudinal end of the third fence 14 and the other longitudinal end of the second fence 13 are detachably connected via a third corner beam 18, and the other longitudinal end of the third fence 14 and the other longitudinal end of the fourth fence 15 are detachably connected via a fourth corner beam 19, and the third corner beam 18 and the fourth corner beam 19 extend longitudinally respectively.

[0069] That is, along the circumferential direction, the first rail 12, the first corner beam 16, the second rail 13, the second corner beam 17, the third rail 14, the third corner beam 18, the fourth rail 15, and the fourth corner beam 19 are detachably connected to form the rigid outer frame 10 of the bathtub to accommodate the soft bathtub body 20. This arrangement facilitates installation and provides reliable circumferential connection.

[0070] Exemplarily, referring to FIG8 , along the longitudinal direction, the bottom of the rigid outer frame 10 has a light-transmitting structure 101. Exemplarily, as shown in FIG8 , along the longitudinal direction, each fence is higher than each corner beam to form the four aforementioned light-transmitting structures 101. That is, a light-transmitting structure 101 is provided on each side of the four sides of the rigid outer frame 10. Each corner beam (the first corner beam 16, the second corner beam 17, the third corner beam 18, and the fourth corner beam 19) is in contact with the ground, and each fence (the first fence 12, the second fence 13, the third fence 14, and the fourth fence 15) is spaced apart from the ground along the longitudinal direction to form the aforementioned light-transmitting structure 101. In some possible embodiments, a light-transmitting structure 101 is provided on one, two, or three sides of the four sides of the rigid outer frame 10.

[0071] The light-transmitting structure 101 exposes the soft cell body 20 housed within the hard cell body cavity 11. A light-emitting component (not shown) is located on the outer surface of the soft cell body 20, corresponding to the light-transmitting structure 101. This means that the user can see the light-emitting component on the outer surface of the soft cell body 20 through the light-transmitting structure 101 on the hard outer frame 10. When powered, the light-emitting component emits light, which is displayed at the location of the light-transmitting structure 101, enhancing the user experience and making it more enjoyable.

[0072] For example, the structures of the four fences (first fence 12, second fence 13, third fence 14, and fourth fence 15) of the present application are all the same. Referring to Figures 5 and 6, the structure of the first fence 12 is used as an example below, and the structures of the remaining fences refer to the structure of the first fence 12.

[0073] The first fence 12 includes: an upper crossbeam 121, a lower crossbeam 122, a connecting plate 124 and a plurality of vertical beams 123. Correspondingly, the second fence 13, the third fence 14 and the fourth fence 15 respectively include: an upper crossbeam 121, a lower crossbeam 122, a connecting plate 124 and a plurality of vertical beams 123. The structure of the first fence 12 is described as an example. The upper crossbeam 121 of the first fence 12 and the lower crossbeam 122 of the first fence 12 are spaced apart along the longitudinal direction (as shown in the Z direction in Figures 5 and 6) and extend in directions perpendicular to the longitudinal direction respectively. Figures 5 and 6 show that the upper crossbeam 121 and the lower crossbeam 122 of the first fence 12 extend in the first direction (as shown in the X direction in Figures 5 and 6). The plurality of vertical beams 123 of the first fence 12 extend in the longitudinal direction respectively and are connected to the upper crossbeam 121 and the lower crossbeam 122 respectively. 5 shows that the first fence 12 includes three vertical beams 123, which are spaced apart along the extension direction of the first fence 12. The two vertical beams 123 at both ends of the extension direction of the first fence 12 are used to be detachably connected to corresponding corner beams, which will be explained in detail later.

[0074] The number of the vertical beams 123 of the first fence 12 is not limited. In other embodiments, the number of the vertical beams 123 of the first fence 12 is, for example, two, four, or the like.

[0075] The connecting plate 124 of the first fence 12 extends in the same direction as the upper crossbeam 121 and the lower crossbeam 122 of the first fence 12. That is, the connecting plate 124 of the first fence 12 extends in a direction perpendicular to the longitudinal direction. In other words, the connecting plate 124 of the first fence 12 is parallel to the upper crossbeam 121 and the lower crossbeam 122 of the first fence 12. In addition, the connecting plate 124 of the first fence 12 is located between the upper crossbeam 121 and the lower crossbeam 122 in the longitudinal direction and is connected to the upper crossbeam 121, the lower crossbeam 122, and the vertical beams 123. In other words, the first fence 12 is formed by connecting the upper crossbeam 121, the lower crossbeam 122, the plurality of vertical beams 123, and the connecting plate 124.

[0076] For example, with continued reference to Figures 5 and 6, the first fence 12 has three connecting plates 124 in the longitudinal direction, and adjacent connecting plates 124 are stacked in the longitudinal direction, so that the first fence 12 is detachably connected in the longitudinal direction. For example, after the three connecting plates 124 are stacked in the longitudinal direction, they are detachably connected to the upper crossbeam 121, the lower crossbeam 122, and the plurality of vertical beams 123, respectively. The number of connecting plates 124 of the first fence 12 is not limited to three. In some possible embodiments, the number of connecting plates 124 of the first fence 12 is, for example, one, two, four, or the like.

[0077] Referring to FIG6 , adjacent connecting plates 124 are detachably connected via a mortise and tenon structure. The connecting plates 124 are connected to the upper crossbeam 121 and the lower crossbeam 122, respectively, via a mortise and tenon structure. For example, in the longitudinal direction, the upper end of the connecting plate 124 of the first fence 12 is provided with a connecting protrusion 1243, and the lower end is provided with a connecting recess 1242. The upper crossbeam 121 of the first fence 12 is provided with a crossbeam connecting recess 1212 on the side facing the connecting plate 124, and the lower crossbeam 122 of the first fence 12 is provided with a crossbeam connecting protrusion 1221 on the side facing the connecting plate 124. The adjacent connecting plates 124 are detachably connected through the connecting protrusions 1243 and the connecting recesses 1242. The upper crossbeam 121 of the first fence 12 is detachably connected to the connecting protrusion 1243 at the upper end of the connecting plate 124 through the crossbeam connecting recess 1212. The lower crossbeam 122 of the first fence 12 is detachably connected to the connecting recess 1242 at the lower end of the connecting plate 124 through the crossbeam connecting protrusion 1221.

[0078] The present application is not limited to the mortise and tenon structure before the connecting plate 124, and the mortise and tenon structure between the connecting plate 124 and the upper beam 121 and the lower beam 122. All mortise and tenon structures that can achieve detachable connection fall within the scope of protection of the present application.

[0079] Referring to Figure 6 , the connecting plate 124 of the first fence 12 is a hollow structure 1241 that accommodates a portion of the connector between the connecting plate 124 and the vertical beam 123. For example, the connecting plate 124 and the vertical beam 123 of the first fence 12 are connected by screws. After the screws connect the connecting plate 124 and the vertical beam 123, the heads of the screws are received within the hollow structure 1241 of the connecting plate 124. Thus, the hollow structure of the first fence 12 not only reduces the weight of the first fence 12, but also serves to accommodate the heads of the screws, making the fence structure more compact.

[0080] As mentioned above, the two vertical beams 123 at both ends of the extension direction of the first fence 12 are used to be detachably connected to the corresponding corner beams. As shown in Figure 2, the two vertical beams 123 at both ends of the extension direction of the first fence 12 are used to be detachably connected to the first corner beam 16 and the fourth corner beam 19, respectively. The two vertical beams 123 at both ends of the extension direction of the second fence 13 are used to be detachably connected to the first corner beam 16 and the second corner beam 17, respectively. The two vertical beams 123 at both ends of the extension direction of the third fence 14 are used to be detachably connected to the second corner beam 17 and the third corner beam 18, respectively. The two vertical beams 123 at both ends of the extension direction of the fourth fence 15 are used to be detachably connected to the third corner beam 18 and the fourth corner beam 19, respectively.

[0081] Referring to Figure 5, the structure of the vertical beam 123 of the first fence 12 is taken as an example for explanation. The vertical beams 123 at both ends of the first fence 12 are respectively provided with T-shaped blocks 1231, and the T-shaped blocks 1231 extend in the longitudinal direction. The corresponding corner beams are provided with slots 161 that cooperate with the T-shaped blocks 1231 to achieve detachable connection between the vertical beams 123 and the corresponding corner beams. The vertical beam 123 in the middle between the vertical beams 123 at both ends of the above-mentioned first fence 12 is not provided with a T-shaped block 1231. That is, the first corner beam 16 and the fourth corner beam 19 at both ends of the extension direction of the first fence 12 are respectively provided with slots 161 that cooperate with the T-shaped blocks 1231 on the vertical beams 123 at both ends of the first fence 12. The structure of each corner beam is the same. Referring to Figure 7, the structure of the first corner beam 16 is taken as an example for explanation. A slot 161 that cooperates with the T-shaped block 1231 is provided on one side of the vertical beam 123 of the first corner beam 16 facing one side of the first fence 12, and a slot 161 that cooperates with the T-shaped block 1231 is provided on one side of the vertical beam 123 of the first corner beam 16 facing one side of the second fence 13.

[0082] That is, the first corner beam 16 is provided with two slots 161 extending in the longitudinal direction, and each slot 161 is respectively engaged with a T-shaped block 1231 on the vertical beam 123 of the corresponding fence (the first fence 12 and the second fence 13) (see Figure 15). Correspondingly, the second corner beam 17 is provided with two slots 161 extending in the longitudinal direction, and each slot 161 is respectively engaged with a T-shaped block 1231 on the vertical beam 123 of the corresponding fence (the second fence 13 and the third fence 14). The third corner beam 18 is provided with two slots 161 extending in the longitudinal direction, and each slot 161 is respectively engaged with a T-shaped block 1231 on the vertical beam 123 of the corresponding fence (the third fence 14 and the fourth fence 15). The fourth corner beam 19 is provided with two longitudinally extending slots 161, each of which engages with a T-shaped block 1231 on the vertical beam 123 of the corresponding fence (the first fence 12 and the fourth fence 15). This arrangement facilitates the detachable connection between each fence and the corresponding corner beam.

[0083] Continuing with Figure 7 , a support portion 162 is provided at the bottom of each slot 161 of the first corner beam 16. With this arrangement, on the one hand, the T-shaped block 1231 on the vertical beam 123 of the corresponding fence (the first fence 12 and the second fence 13) is inserted longitudinally, upward and downward, into the slot 161 for a snap-fit ​​engagement, and the corresponding fence is then supported by the support portion 162. Furthermore, the support portion 162 supports the corresponding fence, allowing the fence to be higher than the corner beam, thereby forming the aforementioned light-transmitting structure 101.

[0084] 16 and 17 , the vertical beams 123 at the left and right ends of the first fence 12 in the direction of extension are respectively provided with a first flange 1233 and a second flange 1235 extending in the longitudinal direction. The first flange 1233 is fitted and connected to the portion of the connecting plate 124 facing the soft pool body 20, and the second flange 1235 is fitted and connected to one end of the connecting plate 124 in the direction of extension. The first flange 1233 of the vertical beams 123 at both ends of the first fence 12 is located on the same side of the first fence 12 (the side of the connecting plate 124 facing the soft pool body 20), and the second flange 1235 of the vertical beams 123 at both ends of the first fence 12 is located on opposite sides of the direction of extension of the connecting plate 124. After the first flange 1233 and the second flange 1235 are provided, the two vertical beams 123 at the left and right ends of the first fence 12 are self-limiting, which facilitates the fitting installation of the vertical beams 123 and the connecting plate 124. That is, when connecting the two vertical beams 123 at the left and right ends of the first fence 12 with the connecting plate 124, as long as the first flange 1233 and the second flange 1235 of the corresponding vertical beam 123 are respectively fitted with the connecting plate 124, the first flange 1233 and the second flange 1235 will play a limiting role, which is beneficial for subsequent connection, such as screw connection.

[0085] In some possible embodiments, with continued reference to Figures 16 and 17, the vertical beam 123 is a hollow structure 1232, with a first block 1234 being accommodated at one longitudinal end of the vertical beam 123, and a second block 1234 being accommodated at the other longitudinal end of the vertical beam 123 (not shown in the figure, but reference can be made to the structure of the first block 1234). The upper crossbeam 121 is connected to the vertical beam 123 via the first block 1234, and the lower crossbeam 122 is connected to the vertical beam 123 via the second block. Since the vertical beam 123 is a hollow structure 1232, it can reduce weight. At the same time, the hollow vertical beam 123 is connected to the upper crossbeam 121 at one longitudinal end via the first block 1234, and to the lower crossbeam 122 at the other longitudinal end via the second block, and the connection method is, for example, screw connection.

[0086] With reference to Figures 18 to 20, in the present application, an anti-slip structure 12343 is provided on the outer peripheral surface of each of the first and second blocking blocks. The anti-slip structure 12343 is used to abut against the inner wall of the vertical beam 123 after each blocking block is placed in the vertical beam 123. When no external force is applied to each blocking block, each blocking block and the vertical beam 123 do not produce relative motion in the longitudinal direction. For example, the first blocking block 1234 is in the shape of a square, and an anti-slip structure 12343 is provided on each side surface of the first blocking block 1234, i.e., four anti-slip structures 12343. However, the present application is not limited to this number of anti-slip structures 12343. In some possible embodiments, the number of anti-slip structures 12343 is, for example, two, three, or five. After the anti-slip structure 12343 is set on the outer peripheral surface of the blocking block, the blocking block cannot slide in the vertical beam 123, but it is not difficult for the blocking block to enter the vertical beam 123, which facilitates assembly and effectively connects the blocking block and the vertical beam 123.

[0087] Illustratively, each anti-slip structure 12343 extends longitudinally. Illustratively, in the longitudinal direction, the depth of the anti-slip structure 12343 is the same as the depth of the blocking block. This arrangement increases the contact force between the blocking block and the inner wall of the vertical beam 123 after it is placed inside the vertical beam 123.

[0088] For example, except for the anti-slip structure 12343, the rest of the outer circumference of each block is in clearance with the inner wall of the vertical beam 123. The anti-slip structure 12343 abuts against the inner wall of the vertical beam 123 to limit the relative movement of the block and the vertical beam 123 in the longitudinal direction. When connecting the upper crossbeam 121 and the lower crossbeam 122 to the vertical beam 123, the block is placed at the opening of the vertical beam 123 and knocked to insert the block into the vertical beam 123. After the block is completely inserted into the vertical beam 123 (no protrusion in the longitudinal direction), the block will not move relative to the vertical beam 123, thereby facilitating the connection of the first block 1234 to the upper crossbeam 121 and the second block to the lower crossbeam 122.

[0089] For example, the first block 1234 and the second block have the same structure. Referring to FIG19 , the structure of the first block 1234 is used as an example. The anti-slip structure 12343 on the outer periphery of the first block 1234 is V-shaped. That is, the projection of the anti-slip structure 12343 is V-shaped in the longitudinal direction.

[0090] Continuing with reference to Figures 17 to 20, each block is mated with the inner wall of the vertical beam 123 in a concave-convex manner. As shown in Figure 17, an inner wall recess 12321 and an inner wall convex 12322 are provided on one side of the inner wall of the vertical beam 123, and the inner wall recess 12321 and the inner wall convex 12322 are arranged adjacent to each other. Referring to Figure 19, the surface of the inner wall of the first block 1234 facing the vertical beam 123 is provided with a block convex 12342 mating with the inner wall recess 12321, and a block recess 12341 mating with the inner convex 12322. Referring to Figure 20, after the first block 1234 is placed in the vertical beam 123, the inner wall recess 12321 and the block convex 12342 are mated in a concave-convex manner, and the inner wall convex 12322 and the block recess 12341 are mated in a concave-convex manner.

[0091] The block and the inner wall of the vertical beam 123 are not in plane-to-plane contact, but in concave-convex contact. Each block is fixedly connected to the inner wall of the vertical beam 123 by screws at the concave-convex contact, and the concave-convex structure between the block and the inner wall of the vertical beam 123 is fixed with self-tapping screws. That is, the inner wall concave portion 12321 is fixedly connected to the block convex portion 12342 by screws after the concave-convex fit, and the inner wall convex portion 12322 is fixedly connected to the block concave portion 12341 by screws after the concave-convex fit. For example, the dotted line L in Figure 20 represents a screw. Compared to the "plane-to-plane contact" between the block and the inner wall of the vertical beam 123, the concave-convex design between the block and the inner wall of the vertical beam 123 acts as a reinforcing rib, and there are more areas for screw connection, so that the connection between the block and the vertical beam 123 is more stable.

[0092] From the above description, it can be seen that adjacent fences are detachably connected in the circumferential direction through corner beams, and each fence is detachably connected in the longitudinal direction through an upper crossbeam 121, a lower crossbeam 122, a connecting plate 124 and multiple vertical beams 123.

[0093] 4 to 13 , the upper crossbeam 121 of each fence of the present invention is concave-convexly matched with the connecting portion 22 of the soft pool body 20 . This arrangement facilitates the connection between the soft pool body 20 and the outer frame 10 .

[0094] For example, referring to Figures 5 and 6 , the upper crossbeam 121 of each fence is provided with a groove 1211 that extends in the same direction as the upper crossbeam 121. Referring to Figure 13 , the connection portion 22 of the soft pool body 20 is provided with a protrusion 222 on the side facing the upper crossbeam 121. The protrusion 222 fits in the groove 1211 in a concave-convex manner. The connection portion 22 of the soft pool body 20 shown in Figure 13 is provided with multiple protrusions 222 on each of the four sides. The multiple protrusions 222 are generally strip-shaped, and the connection portion 22 of the soft pool body 20 is snapped into the groove 1211 of the upper crossbeam 121 via the protrusions 222. Figure 13 shows four protrusions 222 on each side of the connection portion 22 of the soft pool body 20, but the number of protrusions 222 is not limited to this. In some possible embodiments, the number of protrusions 222 on each side of the connection portion 22 of the soft pool body 20 can be the same or different, for example, three, five, or the like.

[0095] For example, the connection part 22 of the soft pool body 20 is high-frequency ironed with PVC strips to form the above-mentioned protrusions 222, and the hard PVC strips are high-frequency connected to the PVC mesh. The PVC strips are snapped into the grooves 1211 of the upper crossbeam 121, which makes the connection stable and easy to install.

[0096] Referring to Figures 12 and 13 , the four corners of the connection portion 22 of the flexible pool body 20 are provided with pool body connection holes 221. The connection portion 22 of the flexible pool body 20 is mounted via the four pool body connection holes 221 on the corresponding positioning posts 303 (see Figure 4 ) on the corner beams described later. This allows the four sides of the flexible pool body 20 to be pre-positioned with the fence, facilitating the engagement of the connection portion 22 of the flexible pool body 20 with the protrusions 222 into the grooves 1211 of the upper crossbeam 121.

[0097] In some possible embodiments, with reference to Figures 9 to 11, the outer frame 10 further includes: a positioning member, and each corner beam is installed with a positioning member. That is, a first positioning member 30 is installed on the first corner beam 16, a second positioning member 31 is installed on the second corner beam 17, a third positioning member 33 is installed on the third corner beam 18, and a fourth positioning member 32 is installed on the fourth corner beam 19. Exemplarily, the structure of each positioning member is the same, and this application uses the structure of the first positioning member 30 as an example. As shown in Figures 10 and 11, the first positioning member 30 includes a positioning member body 301, and the shape of the positioning member body 301 is similar to the shape of the corresponding corner beam. That is, after the positioning member body 301 is installed on the corner beam, the positioning member body 301 can cover the corresponding corner beam.

[0098] For example, the locating member body 301 on the first locating member 30 covers the installed first corner beam 16. The above-mentioned corner beam is a hollow structure, having a corner beam cavity 163 extending longitudinally, which can achieve weight reduction. The above-mentioned first locating member 30 includes a tubular structure 302, which is arranged on the side of the first locating member 30 facing the first corner beam 16, and the tubular structure 302 is inserted into the hollow structure of the first corner beam 16 (i.e., in the corner beam cavity 163) so that the first locating member 30 is installed on the first corner beam 16 and covers the first corner beam 16 (as shown in Figure 9). Through the pipe-in-pipe structure (the tubular structure 302 is inserted into the hollow structure of the corner beam), anti-bending and material reduction are achieved.

[0099] The positioning member body 301 is provided with a protruding positioning post 303. The portion of the pool body connection hole 221 on the connecting portion 22 of the soft pool body 20 corresponding to the corner beam is mounted on the positioning post 303. In other words, the four pool body connection holes 221 on the connecting portion 22 of the soft pool body 20 are respectively mounted on the positioning posts 303 on the first positioning member 30, the positioning posts 303 on the second positioning member 31, the positioning posts 303 on the third positioning member 33, and the positioning posts 303 on the fourth positioning member 32, thereby pre-aligning the four sides of the soft pool body 20 with the fence.

[0100] As shown in Figure 11, the outer surface of the positioning column 303 is provided with a first anti-slip structure 3031, which is used to prevent the connection part 22 from slipping off the positioning column 303 after the pool body connection hole 221 on the connection part 22 of the soft pool body 20 is sleeved on the positioning column 303. In the longitudinal direction, the positioning column 303 and the first anti-slip structure 3031 on the positioning column 303 protrude from the soft pool body 20, so that the four sides of the soft pool body 20 and the pre-positioning of the fence are stable. Exemplarily, the overall structure of the positioning column 303 is a cylindrical boss with ears (first anti-slip structure 3031), which is used to hang the soft pool body 20 and has an anti-slip function.

[0101] Continuing with reference to Figures 10 and 11 , the positioning member body 301 further includes a first extension portion 304 and a second extension portion 305. The first extension portion 304 extends into one of the grooves 1211 of the adjacent upper crossbeam 121 and is fixedly connected thereto, while the second extension portion 305 extends into the other of the grooves 1211 of the adjacent upper crossbeam 121 and is fixedly connected thereto. Exemplarily, the first extension portion 304 and the second extension portion 305 are perpendicular to each other. Exemplarily, the first extension portion 304 and the second extension portion 305 on the positioning member body 301 are flush with the longitudinal top end of the fence.

[0102] For example, the first extension portion 304 of the first positioning member 30 is located within and fixedly connected to one end of the groove 1211 of the first fence 12, and the second extension portion 305 of the first positioning member 30 is located within and fixedly connected to one end of the groove 1211 of the second fence 13. The first extension portion 304 of the second positioning member 31 is located within and fixedly connected to the other end of the groove 1211 of the second fence 13, and the second extension portion 305 of the second positioning member 31 is located within and fixedly connected to one end of the groove 1211 of the third fence 14. The first extension portion 304 of the third positioning member 33 is located within and fixedly connected to the other end of the groove 1211 of the third fence 14, and the second extension portion 305 of the third positioning member 33 is located within and fixedly connected to one end of the groove 1211 of the fourth fence 15. The first extension portion 304 of the fourth positioning member 32 is located within and fixedly connected to the other end of the groove 1211 of the fourth fence 15, and the second extension portion 305 of the fourth positioning member 32 is located within and fixedly connected to the other end of the groove 1211 of the third fence.

[0103] Thus, the first fence 12, the first positioning member 30, the first corner beam 16, the second fence 13, the second positioning member 31, the second corner beam 17, the third fence 14, the third positioning member 33, the third corner beam 18, the fourth fence 15, the fourth positioning member 32, and the fourth corner beam 19 are connected, and the various structural members are connected as a whole, making the connection of the outer frame 10 more compact and reliable, and can withstand the tension at the corners after the inner tank is filled with water.

[0104] For example, the aforementioned fixed connection method is a screw connection. The first extension portion 304 is provided with a first screw hole 3041, which is fixedly connected to the groove 1211 of the fence via a screw. The second extension portion 305 is provided with a second screw hole 3051, which is fixedly connected to the groove 1211 of the fence via a screw.

[0105] Continuing to refer to Figures 9 to 11, in some possible embodiments, the positioning member body 301 further includes a third extension portion 306, which is inserted between adjacent fences. That is, the third extension portion 306 is located between the first extension portion 304 and the second extension portion 305. After the first extension portion 304 and the second extension portion 305 are respectively accommodated in the grooves 1211 of the adjacent upper crossbeams 121, the third extension portion 306 is located in the hard pool body accommodating cavity 11 and is located between adjacent fences. That is, the third extension portion 306 of the first positioning member 30 is inserted between the first fence 12 and the second fence 13, the third extension portion 306 of the second positioning member 31 is inserted between the second fence 13 and the third fence 14, the third extension portion 306 of the third positioning member 33 is inserted between the third fence 14 and the fourth fence 15, and the third extension portion 306 of the fourth positioning member 32 is inserted between the fourth fence 15 and the first fence. After such arrangement, adjacent fences are limited and fixed by the third extension portion 306, so that the overall connection of the outer frame 10 is more compact and reliable, and can withstand the tension at the corners after the inner tank is filled with water.

[0106] Continuing to refer to Figures 9 to 11, in some possible embodiments, a positioning connection hole 3032 is provided in the positioning column 303 on the positioning member body 301, which is used to be fixedly connected to the cover plate connection hole 454 (refer to Figures 22 and 23) on the cover plate assembly 45 described later. The cover plate assembly 45 serves a decorative purpose and is used to cover the connection portion 22 of the soft pool body 20. Exemplarily, the positioning connection hole 3032 in the positioning column 303 and the cover plate connection hole 454 are fixedly connected by screws. This realizes the edge decoration of the outer frame 10 of the detachable bathtub, that is, the decoration of the upper crossbeam 121 of the fence. In addition, the cover plate assembly 45 is detachable and retractable.

[0107] That is, after the four sides of the connecting portion 22 of the above-mentioned soft pool body 20 are pre-positioned with the fence, and the connecting portion 22 of the soft pool body 20 is inserted into the groove 1211 of the upper beam 121 through the protrusion 222, and then connected to the positioning connection hole 3032 in the positioning column 303 on the positioning member body 301 through the cover assembly 45, the cover assembly 45 covers the connecting portion 22 of the soft pool body 20, playing a decorative role.

[0108] For example, after the cover assembly 45 is installed on the outer frame 10, the overall visual effect is close to that of an integrally molded acrylic, and no unnecessary features can be seen.

[0109] Because the cover plate assembly 45 is connected to the positioning connection hole 3032 on the positioning member body 301 to which the corresponding corner beam is mounted, and because the first extension portion 304 and the second extension portion 305 on the positioning member body 301 are respectively fixedly connected to the groove 1211 of the adjacent upper crossbeam 121, the cover plate assembly 45 and the corner beam can be prevented from being pulled out as a whole. This is because the fence, through the first and second extension portions 305, acts as a longitudinal limiter for the positioning member body 301, thereby acting as a longitudinal limiter for the cover plate assembly 45 and the corresponding corner beam.

[0110] In some possible embodiments, referring to Figures 21 to 25 , the cover plate assembly 45 of the present application includes: a first cover plate 41, a second cover plate 42, a third cover plate 43, and a fourth cover plate 44, which are sequentially distributed along the circumference. As described above, the multiple fences enclose the quadrilateral hard pool housing cavity 11, and accordingly, the cover plate assembly 45 of the present application is also quadrilateral as a whole.

[0111] As shown in Figures 1 and 4, the first cover plate 41 and the third cover plate 43 extend respectively in the first direction (shown in the X direction in Figure 21), and the second cover plate 42 and the fourth cover plate 44 extend respectively in the second direction (shown in the Y direction in Figure 21). The first cover plate 41 is covered on the upper crossbeam 121 of the first fence 12 to cover the connection portion 22 of the soft pool body 20 that is clamped with the upper crossbeam 121 of the first fence 12; the second cover plate 42 is covered on the upper crossbeam 121 of the second fence 13. The crossbeam 121 is used to cover the connection part 22 of the soft pool body 20 that is clamped with the upper crossbeam 121 of the second fence 13; the third cover plate 43 is provided on the upper crossbeam 121 of the third fence 14 to cover the connection part 22 of the soft pool body 20 that is clamped with the upper crossbeam 121 of the third fence 14; the fourth cover plate 44 is provided on the upper crossbeam 121 of the fourth fence 15 to cover the connection part 22 of the soft pool body 20 that is clamped with the upper crossbeam 121 of the fourth fence 15.

[0112] In some possible embodiments, each cover plate includes a transition structure 412. Taking the first cover plate 41 as an example, referring to FIG25 , the transition structure 412 of the first cover plate 41 is generally a frame-shaped structure with one end open, including a top surface 4121 located at both ends of the first cover plate 41 in its extension direction, and two side surfaces 4121 and 4122 perpendicularly connected to the top surface 4121 of the transition structure 412. The shape of the transition structure 412 mimics the shape of the upper crossbeam 121 of the first fence 12. When the first cover plate 41 is placed on the upper crossbeam 121 of the first fence 12, the top surface 4121 of the transition structure 412 of the first cover plate 41 is aligned with the top surface of the upper crossbeam 121 of the first fence 12, and the two side surfaces 4121 and 4122 of the transition structure 412 of the first cover plate 41 are aligned with the two side surfaces of the upper crossbeam 121 of the first fence 12, respectively. Equivalently, the first cover plate 41 clamps the upper crossbeam 121 of the first fence 12 through the transition structure 412. Correspondingly, the second cover plate 42 clamps the upper crossbeam 121 of the second fence 13 through the transition structure 412. The third cover plate 43 clamps the upper crossbeam 121 of the third fence 14 through the transition structure 412. The fourth cover plate 44 clamps the upper crossbeam 121 of the fourth fence 15 through the transition structure 412.

[0113] In addition, each cover plate is designed with a transition structure, and the frame-shaped cross-section of the transition structure 412 is resistant to bending, thereby improving the strength of the first cover plate 41. In addition, each cover plate is provided with a plurality of reinforcing ribs on the side facing the fence, and each reinforcing rib is bent.

[0114] Furthermore, along the first direction, one end of the first cover plate 41 and one end of the second cover plate 42 are detachably connected via a first transition piece 45, while the other end of the first cover plate 41 and one end of the fourth cover plate 44 are detachably connected via a second transition piece 48. Along the first direction, one end of the third cover plate 43 and the other end of the second cover plate 42 are detachably connected via a third transition piece 46, while the other end of the third cover plate 43 and the other end of the fourth cover plate 44 are detachably connected via a fourth transition piece 47. In other words, the first cover plate 41, first transition piece 45, second cover plate 42, third transition piece 46, third cover plate 43, fourth transition piece 47, fourth cover plate 44, and second transition piece 48 are detachably connected along the circumferential direction, achieving a removable bathtub rim decoration that is also removable.

[0115] As shown in FIG4 , the positioning post 303 protrudes from the soft pool body 20. Referring also to FIG11 and FIG22 , the first transition piece 45 covers the positioning piece on the first corner beam 16 and is fixedly connected to the connection hole in the positioning post 303 on the first corner beam 16; the second transition piece 48 covers the positioning piece on the second corner beam 17 and is fixedly connected to the connection hole in the positioning post 303 on the second corner beam 17; the third transition piece 46 covers the positioning piece on the third corner beam 18 and is fixedly connected to the connection hole in the positioning post 303 on the third corner beam 18; and the fourth transition piece 47 covers the positioning piece on the fourth corner beam 19 and is fixedly connected to the connection hole in the positioning post 303 on the fourth corner beam 19.

[0116] Thus, the first transition piece 45 covers the portion of the connection portion 22 of the soft pool body 20 corresponding to the first corner beam 16 (i.e., the corner of the connection portion 22), the second transition piece 48 covers the portion of the connection portion 22 corresponding to the second corner beam 17 (i.e., the corner of the connection portion 22), the third transition piece 46 covers the portion of the connection portion 22 corresponding to the third corner beam 18 (i.e., the corner of the connection portion 22), and the fourth transition piece 47 covers the portion of the connection portion 22 corresponding to the fourth corner beam 19 (i.e., the corner of the connection portion 22). Subsequently, the cover plate assembly 45 formed by the first cover plate 41, the first transition piece 45, the second cover plate 42, the third transition piece 46, the third cover plate 43, the fourth transition piece 47, the fourth cover plate 44, and the second transition piece 48, which are detachably connected along the circumference, covers the connection portion 22 of the soft pool body 20.

[0117] Since the first cover plate 41, the first transition piece 45, the second cover plate 42, the third transition piece 46, the third cover plate 43, the fourth transition piece 47, the fourth cover plate 44 and the second transition piece 48 are detachably connected along the circumferential direction, the overall installation is convenient, and after the first transition piece 45, the second transition piece 48, the third transition piece 46 and the fourth transition piece 47 are fixedly connected to the corresponding corner beams, the cover plate assembly 45 is connected to the outer frame 10 and the circumferential direction is limited. The first cover plate 41, the second cover plate 42, the third cover plate 43 and the fourth cover plate 44 will not be separated from the corresponding transition pieces, thereby improving the connection reliability.

[0118] The specific detachable connection method between the cover plates and the corresponding transition pieces in this application is not limited. For example, each cover plate is plugged into the corresponding transition piece. That is, one end of the first cover plate 41 and one end of the second cover plate 42 are respectively plugged into the first transition piece 45, and the other end of the first cover plate 41 and one end of the fourth cover plate 44 are respectively plugged into the second transition piece 48. Along the first direction, one end of the third cover plate 43 and the other end of the second cover plate 42 are respectively plugged into the third transition piece 46, and the other end of the third cover plate 43 and the other end of the fourth cover plate 44 are respectively plugged into the fourth transition piece 47.

[0119] Exemplarily, each cover plate has the same structure, that is, the first cover plate 41, the second cover plate 42, the third cover plate 43, and the fourth cover plate 44 have the same structure. This application takes the structure of the first cover plate 41 and the structure of the first transition piece 45 as examples for explanation. Referring to Figures 24 and 25, the first cover plate 41 is provided with insertion holes 411 at both ends in the extension direction (shown in the X direction in Figure 24), and the first transition piece 45 is provided with a first plug-in portion 452 and a second plug-in portion 451. The first plug-in portion 452 is inserted into one of the insertion holes 411 of the adjacent cover plate, and the second plug-in portion 451 is inserted into the other of the insertion holes 411 of the adjacent cover plate. For example, one end of the first cover plate 41 and one end of the second cover plate 42 are respectively plugged into the first transition piece 45, and accordingly, the first plug-in portion 452 of the first transition piece 45 is inserted into the socket 411 at one end of the extension direction of the first cover plate 41, and the second plug-in portion 451 of the first transition piece 45 is inserted into the socket 411 at one end of the extension direction of the second cover plate 42.

[0120] Correspondingly, the first plug-in portion 452 of the second transition piece 48 is inserted into the insertion hole 411 at the other end of the first cover plate 41 in the direction of extension, and the second plug-in portion 451 of the second transition piece 48 is inserted into the insertion hole 411 at one end of the fourth cover plate 44 in the direction of extension. The first plug-in portion 452 of the third transition piece 46 is inserted into the insertion hole 411 at the other end of the second cover plate 42 in the direction of extension, and the second plug-in portion 451 of the third transition piece 46 is inserted into the insertion hole 411 at one end of the third cover plate 43 in the direction of extension. The first plug-in portion 452 of the fourth transition piece 47 is inserted into the insertion hole 411 at the other end of the fourth cover plate 44 in the direction of extension, and the second plug-in portion 451 of the fourth transition piece 47 is inserted into the insertion hole 411 at one end of the third cover plate 43 in the direction of extension.

[0121] Referring to Figure 22 , in some possible embodiments, the shapes of the first end 4521 and second end 4511 of the first transition piece 45 mimic the shapes of the ends of the corresponding cover plates (first cover plate 41 and second cover plate 42). After one end of the first cover plate 41 and one end of the second cover plate 42 are respectively plugged into the first transition piece 45, the first end 4521 and second end 4511 of the first transition piece 45 align with one end of the first cover plate 41 and one end of the second cover plate 42, respectively. The overall decorative effect is similar to that of a one-piece acrylic molding.

[0122] 22 and 23 , in some possible embodiments, the surfaces of the first plug-in portion 452 and the second plug-in portion 451 are respectively provided with second anti-slip portions 453. The second anti-slip portions 453 are used to abut against the inner wall of the corresponding insertion hole 411 after each plug-in portion is inserted into the corresponding insertion hole 411. When no external force acts on the second anti-slip portions 453, each plug-in portion and the corresponding insertion hole 411 do not produce relative movement in the insertion direction. Exemplarily, the second anti-slip portions 453 are respectively provided on opposite sides of the surfaces of the first plug-in portion 452 and the second plug-in portion 451. The second anti-slip portions 453 snap into the inner wall of the insertion hole 411, ensuring that the first plug-in portion 452 and the second plug-in portion 451 are reliably connected to the corresponding insertion hole 411. For example, the first plug-in portion 452 of the first transition piece 45 is inserted into the socket 411 at one end of the extension direction of the first cover plate 41, and the second anti-slip portion 453 on the first plug-in portion 452 is abutted against the inner wall of the socket 411 at one end of the first cover plate 41. The second plug-in portion 451 of the first transition piece 45 is inserted into the socket 411 at one end of the extension direction of the second cover plate 42, and the second anti-slip portion 453 on the second plug-in portion 451 is abutted against the inner wall of the socket 411 at one end of the second cover plate 42.

[0123] Exemplarily, the second anti-detachment portion 453 is a convex point.

[0124] In some possible embodiments, referring to Figures 22 to 25 , each cover plate's receptacle 411 is curved, and the shape of the corresponding plug-in portion of the receptacle 411 matches the shape of the corresponding receptacle 411. That is, the first plug-in portion 452 and the second plug-in portion 451 corresponding to the receptacle 411 are also curved. This arrangement prevents the transition piece and the corresponding receptacle 411 from slipping off.

[0125] Continuing with reference to FIG. 22 , in some possible embodiments, at least one of the transition pieces is provided with a headrest mounting hole 455 , which is used to mount a corner headrest 70 (as shown in FIG. 1 ). In the present application, headrest mounting holes 455 are provided on all four transition pieces, and accordingly, a corner headrest 70 is mounted on each transition piece. After the corner headrest 70 is mounted on the corresponding transition piece, it covers the corresponding transition piece, thereby obscuring unnecessary features. As shown in FIG. 1 , the four corner headrests 70 completely cover the first transition piece 45 , the second transition piece 48 , the third transition piece 46 , and the fourth transition piece 47 .

[0126] In some possible embodiments, referring to Figures 1 to 3, 14, and 26 to 33, the bathtub of the present application further includes a pipe assembly 60. Exemplarily, the pipe assembly 60 is used for water inlet and outlet. That is, the bathtub of the present application uses the pipe assembly 60 to provide water to the water-holding cavity 21 of the soft body 20 (water inlet) and to drain water from the water-holding cavity 21 of the soft body 20 (water outlet). At least a portion of the pipe assembly 60 is accommodated between the soft body 20 and the hard body accommodating cavity 11. In other words, at least a portion of the pipe assembly 60 is located between the fence of the outer frame 10 and the soft body 20.

[0127] This allows for a piping arrangement between the fence and the soft pool body 20. When the pipe assembly 60 is filled with water, the pipe assembly 60 will not press against the fence, causing the fence to bulge. The pipe assembly 60 is also easy to assemble and maintain.

[0128] Exemplarily, the above-mentioned pipe assembly 60 includes a hard pipe and a soft pipe, and the hard pipe is connected to the soft pipe. That is, the pipe assembly 60 of the present application is formed by connecting the hard pipe and the soft pipe.

[0129] 27 , the pipe assembly 60 of the present application includes an inlet pipe (the heated inlet pipe 61 and the nozzle inlet pipe shown in FIG27 ) and an outlet pipe (the heated outlet pipe 63 and the nozzle outlet pipe 62). Exemplarily, the heated inlet pipe 61 and the nozzle inlet pipe belong to a pipe-in-pipe structure. The above-mentioned inlet pipe of the present application is connected to the soft pool body 20 at one end and to the control box 50 at the other end. For example, the above-mentioned heated inlet pipe 61 is connected to the soft pool body 20 at one end and to the control box 50 at the other end. The above-mentioned outlet pipe is connected to the soft pool body 20 at one end and to the control box 50 at the other end. For example, the above-mentioned heated outlet pipe 63 is connected to the soft pool body 20 at one end and to the control box 50 at the other end. The above-mentioned nozzle outlet pipe 62 is connected to the soft pool body 20 at one end and to the control box 50 at the other end. Exemplarily, one end of the water inlet pipe is connected to the soft pool body 20 by high-frequency ironing, and one end of the water outlet pipe is connected to the soft pool body 20 by high-frequency ironing.

[0130] Exemplarily, referring to Figure 9, the second fence 13 is provided with an opening, one end of the above-mentioned water inlet pipe passes through the opening on the second fence 13 and is connected to the soft pool body 20, and one end of the above-mentioned water outlet pipe passes through the opening on the second fence 13 and is connected to the soft pool body 20.

[0131] In some possible embodiments, the water inlet pipe of the present application includes a soft water inlet pipe and a first hard water inlet pipe and a second hard water inlet pipe located at both ends of the soft water inlet pipe. The first hard water inlet pipe is connected to the soft pool body 20, and the second hard water inlet pipe is connected to the control box 50. For example, the nozzle water inlet pipe includes a soft water inlet pipe 642 and a first hard water inlet pipe 643 and a second hard water inlet pipe 641 located at both ends of the soft water inlet pipe 642. The soft water inlet pipe is located between the second hard water inlet pipe 641 of the nozzle water inlet pipe and the heating water inlet pipe 61. The portion of the heating water inlet pipe 61 that is high-frequency-welded to the soft pool body 20 is a hard pipe, that is, the portion between the hard pipe of the heating water inlet pipe 61 and the second hard water inlet pipe 641 of the nozzle water inlet pipe is a soft water inlet pipe.

[0132] In some possible embodiments, the water outlet pipe includes a soft water outlet pipe and a first hard water outlet pipe and a second hard water outlet pipe located at both ends of the soft water outlet pipe. The first hard water outlet pipe is connected to the soft pool body 20, and the second hard water outlet pipe is connected to the control box 50. For example, the nozzle water outlet pipe 62 described above includes a soft water outlet pipe 621 and a first hard water outlet pipe 623 and a second hard water outlet pipe 622 located at both ends of the soft water outlet pipe 621. For example, the heating water outlet pipe 63 includes a soft water outlet pipe and a first hard water outlet pipe and a second hard water outlet pipe located at both ends of the soft water outlet pipe.

[0133] Since the pipe assembly 60 between the control box 50 and the soft pool body 20 of the bathtub of the present application is formed by connecting a hard pipe and a soft pipe, compared with the connection between the soft pool body 20 and the control box 50 of the bathtub through a hard pipe, water circulates with each other. After the single-layer soft pool body 20 is filled with water, the water pressure is different at different water depths, and the degree of concave state of the single-layer soft pool body 20 is different, which can ensure that the pipe assembly 60 will not bulge on the soft pool body 20, but automatically adjust the degree of bulge as the water depth changes.

[0134] The connection between the above-mentioned hose and the hard pipes at both ends can adopt the waterproof structure described later. Please refer to the description below for details.

[0135] In addition, a rigid support structure is provided within the aforementioned soft water inlet or outlet pipe. For example, a rigid support structure (e.g., a hard pipe) is provided within the soft outlet pipe 621 of the nozzle outlet pipe 62. This rigid support structure within the soft outlet pipe 621 can overcome the negative pressure generated during operation, ensuring that the nozzle outlet pipe 62 can discharge water normally.

[0136] In some possible embodiments, referring to Figures 26 to 28, a water inlet branch is provided between the soft pool body 20 and the hard pool body accommodating cavity 11. Exemplarily, an annular cavity is provided between the bottom of the soft pool body 20 and the bottom of the hard pool body accommodating cavity 11, and the water inlet branch is provided in the annular cavity of the soft pool body 20 and the hard pool body accommodating cavity 11. That is, the water inlet branch in the pipe assembly 60 is hidden in the bathtub, which looks beautiful. Exemplarily, the above-mentioned water inlet branch includes a plurality of multi-way hard tubes 644, 643 and a hose 645, and the adjacent multi-way hard tubes 644, 643 are connected by a hose 645, and the multi-way hard tube 644 is provided with a plurality of nozzles 65. Exemplarily, the above-mentioned hose 645 is a TPU tube or a silicone tube. In some possible embodiments, a water outlet branch is provided in the annular cavity.

[0137] Thus, the pipe assembly is built in between the outer frame 10 and the soft pool body 20 of the bathtub. The pipe layout between the outer frame 10 and the soft pool body 20 is realized. After water is filled, the pipe assembly will not press against the fence, causing the fence to bulge.

[0138] Exemplarily, the multi-way rigid tube 644 is a four-way rigid tube, with hoses 645 connected at both ends, and each of the hoses 645 is connected to two nozzles 65. Figure 27 shows four multi-way rigid tubes 644 and eight nozzles 65. However, this application does not limit the number of multi-way rigid tubes 644. Spraying water to the user through multiple nozzles 65 provides a good user experience.

[0139] In some possible embodiments, referring to Figures 29 to 33 , waterproof structures are provided between the aforementioned rigid and flexible pipes of the present application. For example, a waterproof structure is provided between the rigid and flexible pipes in the heating water inlet pipe 61, the nozzle water inlet pipe, the heating water outlet pipe 63, and the nozzle water outlet pipe 62 shown in Figure 27 . For another example, a waterproof structure is provided between the multi-way rigid pipes 644 and 643 and the flexible pipe 645 in the aforementioned water inlet manifold, and a waterproof structure is provided between the aforementioned nozzle 65 and the multi-way rigid pipe 644.

[0140] Taking the waterproof structure in the water inlet manifold as an example, the waterproof structure in other pipe components 60 (such as the water outlet pipe) is the same as the waterproof structure in the water inlet manifold. Specifically, one end of the hard pipe 644 in the water inlet manifold that is connected to the hose 645 is provided with an external thread structure 6441 surrounding the water inlet port of the hard pipe 644. The external thread structure 6441 is connected to the hard pipe 644 via a limit block 6442. For example, the limit block 6442 is perpendicular to the hard pipe 644. The limit block 6442, the external thread structure 6441, and the hard pipe 644 form a waterproof cavity 6443 with an open end. As shown in Figures 31 to 33, four waterproof cavities 6443 are formed on the multi-way hard pipe 644 of the water inlet manifold.

[0141] The outer circumference of the aforementioned hose 645 is provided with a conical pressure ring 6452 and a locking nut 6451. The hose 645 is inserted into the waterproof cavity 6443. The insertion direction of the hose 645 is shown in the direction C in Figures 30 and 32. The locking nut 6451 is threadedly connected to the external thread structure 6441. Along the insertion direction of the hose 645, the conical pressure ring 6452 is located between the end of the external thread structure 6441 and the locking nut 6451. The conical pressure ring 6452 clamps the hose 645 along the insertion direction with the end of the rigid tube 644. For example, during the threaded connection of the locking nut 6451 with the external thread structure 6441, the conical pressure ring 6452 moves toward the rigid tube 644 along the insertion direction. When the locking nut 6451 is fully connected to the external thread structure 6441, the conical pressure ring 6452 and the end of the rigid tube 644 clamp the hose 645. That is, the travel of the locking nut 6451 on the external thread structure 6441 enables the conical pressure ring 6452 to clamp the hose 645 together with the end of the hard tube 644 .

[0142] Compared to the current industry practice of achieving waterproofing through gluing, configuring sealing rings, and locking throat clamps, this application achieves waterproofing through a purely mechanical connection structure. By rotating the locking nut 6451, the hard conical pressure ring 6452 on the hose 645 (TPU tube or silicone tube) is pressed against the end of the hard tube 644 in the insertion direction. The conical pressure ring 6452, the hose 645, the end of the hard tube 644, and the locking nut 6451 are interconnected to achieve waterproofing.

[0143] In some possible embodiments, the end of the rigid tube 644 has a tapered surface 6444. The tapered pressure ring 6452 and the tapered surface 6444 clamp the flexible tube in the insertion direction. That is, the tapered pressure ring 6452 and the tapered surface 6444 at the end of the rigid tube 644 cooperate to clamp the flexible tube in the insertion direction, improving waterproof performance. The tapered surface 6444 at the end of the rigid tube 644 also serves to guide the flexible tube 645 into the waterproof cavity 6443.

[0144] Exemplarily, the waterproof structure between the above-mentioned soft water inlet pipe (equivalent to the hose 645) and the first hard water inlet pipe (equivalent to the hard pipe 644), the waterproof structure of the soft water inlet pipe (equivalent to the hose 645) and the second hard water inlet pipe (equivalent to the hard pipe 644), the waterproof structure of the soft water outlet pipe (equivalent to the hose 645) and the first hard water outlet pipe (equivalent to the hard pipe 644), and the waterproof structure of the soft water outlet pipe (equivalent to the hose 645) and the second hard water outlet pipe (equivalent to the hard pipe 644) are the same as the above-mentioned waterproof structure between the above-mentioned hard pipe 644 and the hose 645.

Those skilled in the art may make various changes in form and detail, including simple deductions or substitutions, without departing from the spirit and scope of the present invention.
