Abstract
Description
Technical fields:
[0001] This utility model relates to the field of bathroom equipment technology, specifically to a concealed massage bathtub. Background technology:
[0002] Existing massage bathtubs still have many shortcomings in practical use. Traditional massage components (such as massage heads and rollers) are mostly exposed, protruding from the inner wall or bottom of the bathtub. This not only disrupts the overall smooth design of the bathtub and affects the aesthetic harmony of the bathroom space, but also easily creates cleaning dead spots at the connection between the massage components and the bathtub body. Water stains and shower gel residue easily accumulate here, leading to bacterial growth over time and increasing the workload of daily cleaning. Furthermore, traditional massage components are mostly rigid and fixed structures, and the contact pressure with the skin cannot be adjusted. This can cause pressure or discomfort for people with different sensitivity levels (such as the elderly and children), resulting in a poor massage experience. In addition, existing massage components are mostly installed as a single unit. When the massage components wear out or deform due to long-term friction, or when internal components malfunction, the entire massage roller or even the entire massage structure must be disassembled, which is not only cumbersome but also increases replacement costs and maintenance time. To address these problems, this utility model proposes a concealed massage bathtub to solve the shortcomings and drawbacks of existing technologies. Utility model content:
[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a concealed massage bathtub.
[0004] The technical solution adopted in this utility model is as follows:
[0005] A concealed massage bathtub includes a bathtub, a support layer, a waterproof and wear-resistant layer, and a built-in massage structure. The support layer is provided on both sides of the bottom of the bathtub, and an opening is provided between the support layers above the built-in massage structure. The waterproof and wear-resistant layer is provided on the support layer.
[0006] The built-in massage structure consists of a massage roller, a rotating shaft, a mounting base, and massage components. The massage roller is mounted on the rotating shaft, and both ends of the rotating shaft are mounted in the bathtub via the mounting base. The massage roller has a mounting groove, and the massage components are placed in the mounting groove.
[0007] Preferably, the massage component comprises a mounting block, a positioning block, a piston rod, a piston, a massage ball, and a return spring. The mounting block is detachably mounted in the mounting groove, and the positioning block is detachably mounted on the mounting block. The positioning block is connected to one end of the piston rod, and the piston is fixedly connected to the other end of the piston rod. The massage ball has a cavity for the piston to connect to, and the return spring is sleeved on the piston rod.
[0008] Preferably, the mounting slot has a fixing screw hole, and the mounting block has a through hole. The mounting block is installed in the mounting slot by fixing screws.
[0009] Preferably, the mounting block has a positioning post on its front side, and the bottom of the positioning block has a positioning groove connected to the positioning post. The mounting block, positioning post, and positioning block are connected by a connecting through hole, and the end of the connecting bolt passes through the connecting through hole of the mounting block, positioning post, and positioning block and is threaded to the piston rod.
[0010] Preferably, each of the massage rollers has at least three mounting slots.
[0011] Preferably, each of the mounting blocks has at least one massage element.
[0012] The beneficial effects of this invention are as follows: By setting a support layer at the bottom of the bathtub, the built-in massage structure is hidden between the support layers, achieving the massage effect only through the gaps. This avoids exposing the massage structure and compromising the overall aesthetics, reduces structural gaps, and lowers the difficulty of dirt accumulation and cleaning. This invention can automatically extend and retract to buffer the pressure of human contact, avoiding discomfort caused by rigid contact and adapting to the massage needs of different people. This invention adopts a detachable connection structure; when components such as the massage balls wear out, they can be disassembled and replaced individually without overall disassembly, significantly reducing maintenance costs and operational difficulty, and improving the user experience.

[0019] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.
[0020] like Figure 1-6 As shown, a concealed massage bathtub includes a bathtub 001, a support layer 002, a waterproof and wear-resistant layer 003, and a built-in massage structure 004. The support layers 002 are provided on both sides of the bottom of the bathtub 001. The support layers 002 are made of hard plastic, which not only supports the human body, but also provides installation space for the built-in massage structure 004. An opening 210 is provided between the support layers 002 above the built-in massage structure 004. The waterproof and wear-resistant layer 003 is provided on the support layer 002. The waterproof and wear-resistant layer 003 on the support layer 002 is made of PVC, which can prevent water stains from seeping into the support layer 002, and at the same time improve the wear resistance when the human body comes into contact with it.
[0021] The built-in massage structure 004 consists of a massage roller 410, a rotating shaft 420, a mounting base 430, and massage components 440. The massage roller 410 is mounted on the rotating shaft 420, which is installed in the bathtub 001 at both ends via the mounting bases 430. A driven wheel is mounted on the rotating shaft 420, which can be connected to an external drive motor. The output wheel of the drive motor is connected to the driven wheel, providing power for the rotation of the rotating shaft 420. When the massage roller 410 rotates with the rotating shaft 420, its top extends through the gap 210 between the support layers 002 to the top of the support layer 002 and abuts against the waterproof and wear-resistant layer 003, thus providing a massage to the human body. A mounting groove 411 is provided on the massage roller 410, and the massage components 440 are installed in the mounting groove 411.
[0022] Further optimizations to this solution include: Figure 1-6 As shown, the massage component 440 consists of a mounting block 441, a positioning block 442, a piston rod 443, a piston 444, a massage ball 445, and a return spring 446. The mounting block 441 is detachably mounted in the mounting groove 411. The positioning block 442 is detachably mounted on the mounting block 441. The positioning block 442 is connected to one end of the piston rod 443. The other end of the piston rod 443 is fixedly connected to the piston 444. The massage ball 445 has a cavity 4451 for the piston 444 to connect to. The return spring 446 is sleeved on the piston rod 443.
[0023] Further optimizations to this solution include: Figure 1-6As shown, a fixing screw hole 412 is provided in the mounting groove 411, and a through hole 4411 is provided on the mounting block 441. The mounting block 441 is installed in the mounting groove 411 by fixing screws 4413. Specifically, the mounting block 441 is connected to the fixing screw hole 412 of the mounting groove 411 by fixing screws 4413 passing through the through hole 4411, so as to achieve detachable fixing with the massage roller 410.
[0024] Further optimizations to this solution include: Figure 1-6 As shown, the mounting block 441 has a positioning post 4414 on the front side, and the positioning block 442 has a positioning groove 4421 at the bottom that is connected to the positioning post 4414. The mounting block 441, the positioning post 4414, and the positioning block 442 are connected by a connecting through hole 4415. The end of the connecting bolt 4416 passes through the connecting through hole 4415 of the mounting block 441, the positioning post 4414, and the positioning block 442 and is threadedly connected to the piston rod 443.
[0025] Further optimizations to this solution include: Figure 1-6 As shown, each massage roller 410 has at least three mounting slots 411.
[0026] Further optimizations to this solution include: Figure 1-6 As shown, each mounting block 441 has at least one massage element 440. Through the synergistic effect of multiple massage elements 440, the massage coverage and comfort are improved.
[0027] During massage, the massage ball 445 indirectly contacts the human body through the built-in massage structure 004. The piston rod 443 is pushed by the piston 444 to retract into the cavity 4451. The return spring 446 is compressed to generate a buffering force, avoiding rigid contact. After the contact is broken, the return spring 446 returns to its original position, pushing the massage ball 445 back to its original position, thus achieving a gentle massage. When the massage ball 445 is worn, the connecting bolt 4416 can be removed separately to replace the massage component 440, without having to replace the entire massage roller 410. Furthermore, different numbers of massage balls 445 can be replaced according to the massage intensity.
