Description

Technical Field

[0001] This utility model relates to the field of home furnishing products, specifically to a bathtub. Background Technology

[0002] In the prior art, bathtubs typically include a tub and a massage pillow. The massage pillow is installed on the tub and has a drive unit and a massage component. The drive unit drives the massage component to rotate and massage. Because the distance between the two drive shafts of the drive unit is fixed, the massage component can only rotate and massage along the drive shaft. Since everyone's neck width is different, the massage effect is poor. Utility Model Content

[0011] Option 5, based on Options 2 to 4, further includes a protective shell, a first sealing element, and a pressure cap. The cylinder body has a first surface and a second surface, and mounting holes with openings at both ends on the first surface and the second surface, respectively. The first sealing element is adapted to abut against the walls of the first surface, the second surface, and the mounting holes. The pressure cap is fixedly connected to the protective shell and abuts against one side of the fixing seat. The other side of the fixing seat and the first surface together clamp a portion of the first sealing element. The protective shell and the second surface together clamp a portion of the first sealing element. The main body of the driving element is installed inside the protective shell, and its output shaft is adapted to pass through the mounting hole.

[0012] Option 6, based on Option 5, further includes a second sealing element, a first through hole in the protective shell, an output shaft of the drive unit adapted to pass through the first through hole, a pressure cap adapted to connect with the first through hole, and adapted to clamp the second sealing element together with the hole wall of the first through hole.

[0013] Option 7, based on Option 6, further includes a third sealing element, and the pressure cover is provided with a second through hole, the second through hole and the output shaft of the drive member being adapted to jointly clamp the third sealing element.

[0014] Option 8, based on Option 7, wherein the third seal is a V-shaped seal, the third seal has a lip, and the lip faces a direction parallel to the first direction and close to the massage component.

[0015] Option 9, based on Option 1, involves the centerline of the massage unit not coinciding with the rotation axis of the output shaft, and extending obliquely in a direction away from the rotation axis of the output shaft.

[0016] As can be seen from the above description of the present invention and its preferred embodiments, compared with the prior art, the technical solution of the present invention and its preferred embodiments have the following beneficial effects due to the adoption of the following technical means:

[0017] 1. In Scheme 1 and its preferred embodiments, a bathtub includes a tub body and a massage pillow. The massage pillow includes a drive member and two massage components; the output shaft of the drive member is adapted to rotate about an axis parallel to a first direction to directly or indirectly drive the massage components to move.

[0018] The massage assembly includes a massage section adapted to eccentrically oscillate around an axis parallel to a first direction, thereby changing the position of the massage section. When activated, the drive unit is adapted to cause the massage section to eccentrically oscillate around an axis parallel to the first direction, bringing the massage sections of the two massage assemblies closer together or further apart to knead the neck. Because the position of the massage section can change when the drive unit is activated, it tends to move closer to or further away from the neck. By bringing the massage sections of the two massage assemblies closer together or further apart, the neck muscles are squeezed or relaxed, thus kneading the neck and achieving a massage effect. Since the eccentric oscillation, in addition to its rotational movement around the output shaft axis, also has undulating characteristics, it can adapt to varying neck widths, improving the massage effect.

[0019] 2. In Scheme 2 and its preferred embodiment, the rotating component is provided with an abutting inclined surface, and the output shaft of the driving component is connected to the rotating component to prevent rotation, so that the rotating component is suitable for rotating around an axis parallel to the first direction; the fixed seat is provided with a limiting groove; the massage component is located on the abutting inclined surface, and the massage component is provided with a limiting block extending into the limiting groove, the limiting block and the groove wall of the limiting groove are suitable for abutting each other to limit, and are suitable for repeatedly sliding in the limiting groove.

[0020] When the drive unit is turned on, the rotating part rotates around an axis parallel to the first direction, and abuts against the inclined surface to act on the massage component. Due to the limiting effect of the limiting block and the groove wall, the massage component does not rotate with the rotating part around an axis parallel to the first direction. Instead, it is driven by the abutting inclined surface to achieve undulation in different areas. Furthermore, the eccentric swing is achieved by the limiting block repeatedly sliding in the limiting groove. During the eccentric swing, the massage parts of the two massage components move closer or further apart to squeeze or relax the neck muscles, thereby kneading the neck.

[0021] 3. In Scheme 3 and its preferred embodiments, the rotating component includes an eccentric seat and a limiting seat fixedly connected to each other. The eccentric seat has an abutting inclined surface, and the limiting seat has a limiting surface. The massage component includes a massage component and an eccentric swing seat fixedly connected to each other. The massage component has a massage part, and the eccentric swing seat is located on the abutting inclined surface. The eccentric swing seat has a limiting surface facing the limiting surface. Through the function of the limiting surface, the eccentric swing seat can be prevented from detaching from the eccentric seat, thereby ensuring the structural stability during operation.

[0022] There is a clearance between the limiting surface and the limiting surface to prevent the massage component from being clamped by the abutting slope of the eccentric seat and the limiting surface of the limiting seat, thereby allowing the massage component to achieve eccentric oscillation.

[0023] 4. In Scheme 4 and its preferred embodiments, the cover is fitted onto the fixing seat and seals with the fixing seat. The cover encloses the rotating component and the massage component, thereby protecting the rotating component and the massage component and preventing dirt and water from entering the rotating component and the massage component, which could cause damage or make them difficult to clean. Furthermore, the cover is elastic, allowing the massage part to transmit force to the neck by deforming the cover. Simultaneously, the cover can also deform to better fit the neck, increasing comfort.

[0024] 5. In Scheme 5 and its preferred embodiments, the massage pillow further includes a protective shell, a first sealing element, and a pressure cap; the cylinder body has a first surface and a second surface, and mounting holes with openings at both ends on the first surface and the second surface, respectively.

[0025] The first seal is adapted to abut against the first surface, the second surface, and the wall of the mounting hole. The gland is fixed to the protective shell and abuts against one side of the fixing seat. The other side of the fixing seat and the first surface together clamp a part of the first seal, thereby preventing water from entering the mounting hole between the fixing seat and the first surface, causing water accumulation and damaging the product.

[0026] The protective shell and the second surface together clamp a portion of the first seal. Even if water enters the mounting hole between the fixing seat and the first surface and then flows out from between the first seal and the wall of the mounting hole, it will not be able to enter the area where the protective shell is located due to the seal here, thus increasing the sealing performance.

[0027] The main body of the drive unit is installed inside a protective housing for protection. The output shaft of the drive unit is adapted to pass through the mounting hole to directly or indirectly move the massage assembly.

[0028] 6. In Scheme Six and its preferred embodiments, the protective shell is provided with a first through hole, the output shaft of the drive component is adapted to pass through the first through hole, and the pressure cap is adapted to connect with the first through hole to realize the installation of the pressure cap. Furthermore, the pressure cap is adapted to clamp the second sealing element together with the hole wall of the first through hole to prevent water from entering the protective shell through the connection between the pressure cap and the first through hole, thus affecting the use of the drive component inside the protective shell.

[0029] 7. In Scheme 7 and its preferred embodiments, the pressure cover is provided with a second through hole, and the output shaft of the drive unit passes through the second through hole. The second through hole and the output shaft of the drive unit are adapted to jointly clamp the third seal to prevent water from entering the protective shell through the second through hole and the output shaft, thus affecting the use of the drive unit inside the protective shell.

[0030] 8. In Scheme 8 and its preferred embodiments, the third seal is a V-shaped seal with a lip. The V-shaped seal is conducive to achieving dynamic sealing and has wear-resistant properties, making it suitable for sealing when the output shaft rotates. The lip faces a direction parallel to the first direction and close to the massage component, which facilitates the output shaft passing through the V-shaped seal and makes it easy to assemble the output shaft with the V-shaped seal.

[0031] 9. In Scheme 9 and its preferred embodiments, the centerline of the massage part does not coincide with the rotation axis of the output shaft, and extends obliquely in a direction away from the rotation axis of the output shaft to increase the massage area. Attached Figure Description

[0051] Unless otherwise expressly defined, the terms "fixed connection" or "fixed connection" used in the claims, description and drawings of this utility model shall be interpreted broadly to refer to any connection in which there is no displacement or relative rotation relationship between the two parties, including non-removable fixed connection, detachable fixed connection, integral connection and fixed connection through other devices or components.

[0052] In the claims, description and accompanying drawings of this utility model, the terms "comprising," "having," and variations thereof are used to mean "including but not limited to."

[0053] refer to Figures 1-13 A bathtub, comprising a tub body 10 and a massage pillow 20.

[0054] refer to Figure 10 The cylinder body 10 is provided with a first surface 101 and a second surface 102, and mounting holes 103 with openings at both ends on the first surface 101 and the second surface 102 respectively. The number of mounting holes 103 is two.

[0055] The massage pillow 20 includes a drive component 1, a massage assembly 2, a fixed base 3, a rotating component 4, a protective shell 6, a cover 5, a first seal 81, a pressure cover 7, a second seal 82, and a third seal 83.

[0056] refer to Figure 10 The driving component 1 includes a main body 11 and output shafts 12. The main body 11 is mainly composed of a motor and transmission components (such as gears). There is one motor, which transmits kinetic energy to two output shafts 12 through the transmission components, so that the two output shafts 12 rotate about an axis parallel to the first direction 9. The output shafts 12 are adapted to pass through the mounting holes 103 and are respectively disposed corresponding to two massage components 2. In other embodiments, there are two motors, and they may not have transmission components. The two motors are respectively disposed corresponding to two massage components 2.

[0057] The number of rotating parts 4 corresponds to the number of massage components 2, which is also two. (Reference) Figure 4 , Figure 7 , Figure 8 The rotating component 4 includes an eccentric seat 41 and a limiting seat 42 fixedly connected to each other. In this embodiment, the eccentric seat 41 and the limiting seat 42 are fastened together by screws. Besides this, the fastening method can also be a snap-fit, adhesive bonding, magnetic connection, or threaded engagement between the eccentric seat 41 and the limiting seat 42. The eccentric seat 41 has an abutting inclined surface 411, which is inclined relative to the first direction 9. The limiting seat 42 has a limiting surface 421, which faces the abutting inclined surface 411 and is adapted to sit on the eccentric seat 41. (Reference) Figure 10 The screw passes through the limiting seat 42 and is screwed to the output shaft 12 to fix the rotating part 4 and the output shaft 12, thereby making the output shaft 12 of the driving part 1 and the rotating part 4 anti-rotation connected, so that the rotating part 4 is suitable for rotating about an axis parallel to the first direction 9.

[0058] Massage component 2 consists of two parts, see reference. Figure 3 The massage assembly 2 includes a massage element 21 and an eccentric swing seat 22 fixedly connected to each other. In this embodiment, the massage element 21 and the eccentric swing seat 22 are fastened together by screws and enclose a receiving cavity 23. Figure 8As shown, the receiving cavity 23 is adapted to receive the limiting seat 42, and the receiving cavity 23 has an opening for the output shaft 12 to extend into. (Reference) Figure 3 The massage component 21 is equipped with a massage section 211, which can be one or multiple. When the output shaft 12 rotates, reference... Figure 12 , Figure 13 The massage unit 211 is adapted to eccentrically oscillate around an axis parallel to the first direction 9 to change the position of the massage unit 211 (specific implementation details are described below). Furthermore, by making the centerline of the massage unit 211 not coincide with the rotation axis of the output shaft 12, and extending obliquely in a direction away from the rotation axis of the output shaft 12, the kneading area can be enlarged. (Reference) Figure 8 The eccentric swing seat 22 rests on the inclined surface 411 under its own weight. The eccentric swing seat 22 has a limiting surface 221 facing the limiting surface 421 to prevent it from detaching from the rotating member 4. A clearance gap 24 exists between the limiting surface 221 and the limiting surface 421 to allow the eccentric swing seat 22 to swing eccentrically. (Reference) Figure 3 The eccentric swing seat 22 is also equipped with a limit block 222.

[0059] Mounting bracket 3 is suitable for fixing relative to cylinder block 10, see reference. Figure 4 , Figure 7 The fixed base 3 is provided with a limiting groove 31. The number of limiting grooves 31 corresponds to the number of massage components 2. The opening of the limiting groove 31 faces the direction perpendicular to the first direction 9. The limiting groove 31 is suitable for the limiting block 222 to extend into it. The limiting block 222 and the groove wall of the limiting groove 31 are suitable to abut against each other for limiting, and are suitable to slide repeatedly in the limiting groove 31.

[0060] refer to Figure 2 The cover 5 is elastic, and the cover 5 is fitted onto the fixed seat 3 and sealed with the fixed seat 3. The cover 5 also covers the rotating part 4 and the massage component 2.

[0061] refer to Figure 10 The protective shell 6 is provided with a first through hole 61, and a threaded section is provided on the first through hole 61. The protective shell 6 is suitable for mounting the main body 11 of the drive component 1, and the output shaft 12 of the drive component 1 extends out from the first through hole 61. The protective shell 6 and the second surface 102 together clamp a part of the first sealing element 81 to achieve a corresponding seal.

[0062] refer to Figure 10 , Figure 11 The first seal 81 is generally H-shaped to fit against the walls of the first surface 101, the second surface 102, and the mounting hole 103.

[0063] refer to Figure 10The pressure cap 7 is fixedly connected to the protective shell 6. In this embodiment, the pressure cap 7 is threadedly engaged with the threaded section on the first through hole 61 to achieve connection. Furthermore, the outer wall of the pressure cap 7 and the wall of the first through hole 61 together clamp the second sealing element 82, which is annular. The pressure cap 7 also has a flange 71, which abuts against one side of the fixing seat 3. The other side of the fixing seat 3 and the first surface 101 together clamp a portion of the first sealing element 81, achieving sealing while the fixing seat 3 is installed. The pressure cap 7 also has a second through hole 72, which and the output shaft 12 of the drive component 1 are adapted to jointly clamp a third sealing element 83. The third sealing element 83 is a V-shaped sealing element with a lip 831 facing a direction parallel to the first direction 9 and close to the massage component 2.

[0064] When using, refer to Figure 7 , Figure 12 , Figure 13 When the drive unit 1 is activated, the rotating unit 4 rotates around an axis parallel to the first direction 9, and abuts against the inclined surface 411 to act on the massage component 2. Due to the limiting effect of the limiting block 222 and the groove wall of the limiting groove 31, the massage component 2 will not rotate with the rotating unit 4 around an axis parallel to the first direction 9. Instead, it is driven by the abutting inclined surface 411 to achieve undulation in different areas. Furthermore, the limiting block 222 slides repeatedly in the limiting groove 31 to achieve eccentric swing. During the eccentric swing, the massage parts 211 of the two massage components 2 move closer or further away from each other to squeeze or relax the neck muscles, thereby kneading the neck.

[0065] In other embodiments, the movement of the drive member 1 can drive the massage component 2 to oscillate eccentrically.

[0066] Compared with the prior art, this embodiment has the following beneficial effects:

[0067] In one exemplary embodiment, a bathtub includes a tub body 10 and a massage pillow 20. The massage pillow 20 includes a drive member 1 and two massage components 2; the output shaft 12 of the drive member 1 is adapted to rotate about an axis parallel to a first direction 9 to directly or indirectly drive the massage components 2 to move.

[0068] The massage assembly 2 is provided with a massage part 211, which is adapted to eccentrically oscillate around an axis parallel to the first direction 9 to change the position of the massage part 211. The drive member 1 is adapted to eccentrically oscillate the massage part 211 around an axis parallel to the first direction 9 when it is turned on, so that the massage parts 211 of the two massage assemblies 2 move closer to each other or further away from each other to knead the neck. Since the position of the massage part 211 can change when the drive member 1 is turned on, the massage part 211 tends to move away from or closer to the neck. By making the massage parts 211 of the two massage assemblies 2 move closer to or further away from each other, the neck muscles are squeezed or relaxed, thereby kneading the neck and achieving the massage effect. Since the eccentric oscillation has the characteristics of undulation in addition to the rotation axis around the output shaft 12, it can adapt to the uneven width of the user's neck and improve the massage effect.

[0069] In one exemplary embodiment, the rotating member 4 is provided with an abutting inclined surface 411, and the output shaft 12 of the driving member 1 is connected to the rotating member 4 to prevent rotation, so that the rotating member 4 is adapted to rotate about an axis parallel to the first direction 9; the fixed base 3 is provided with a limiting groove 31; the massage component 2 is located on the abutting inclined surface 411, and the massage component 2 is provided with a limiting block 222 extending into the limiting groove 31. The limiting block 222 is adapted to abut against the groove wall of the limiting groove 31 to limit, and is adapted to slide repeatedly within the limiting groove 31.

[0070] When the drive unit 1 is turned on, the rotating unit 4 rotates around an axis parallel to the first direction 9, and abuts against the inclined surface 411 to act on the massage component 2. Due to the limiting effect of the limiting block 222 and the groove wall of the limiting groove 31, the massage component 2 will not rotate with the rotating unit 4 around an axis parallel to the first direction 9. Instead, it is driven by the abutting inclined surface 411 to achieve undulation in different areas. Furthermore, the limiting block 222 slides repeatedly in the limiting groove 31 to achieve eccentric swing. During the eccentric swing, the massage parts 211 of the two massage components 2 move closer or further away from each other to squeeze or relax the neck muscles, thereby kneading the neck.

[0071] In one exemplary embodiment, the rotating component 4 includes an eccentric seat 41 and a limiting seat 42 fixedly connected to each other. The eccentric seat 41 is provided with an abutting inclined surface 411, and the limiting seat 42 is provided with a limiting surface 421. The massage component 2 includes a massage component 21 and an eccentric swing seat 22 fixedly connected to each other. The massage component 21 is provided with a massage part 211, and the eccentric swing seat 22 is located on the abutting inclined surface 411. The eccentric swing seat 22 is provided with a limiting surface 221 facing the limiting surface 421. Through the action of the limiting surface 421, the eccentric swing seat 22 can be prevented from detaching from the eccentric seat 41, thereby ensuring the structural stability during operation.

[0072] There is a clearance gap 24 between the limiting surface 221 and the limiting surface 421 so that the massage component 2 is not clamped by the abutting inclined surface 411 of the eccentric seat 41 and the limiting surface 421 of the limiting seat 42, thereby allowing the massage component 2 to achieve eccentric swing.

[0073] In one exemplary embodiment, the cover 5 is fitted onto and sealed to the fixing base 3, and the cover 5 encloses the rotating member 4 and the massage component 2, thereby protecting the rotating member 4 and the massage component 2 and preventing dirt and water from entering the rotating member 4 and the massage component 2, which could cause damage or make them difficult to clean; and the cover 5 is elastic. This allows the massage part 211 to transmit force to the neck by deforming the cover 5. At the same time, the cover 5 can also deform to fit the neck more closely, increasing comfort.

[0074] In one exemplary embodiment, the massage pillow 20 further includes a protective shell 6, a first sealing member 81, and a pressure cap 7. The cylinder 10 is provided with a first surface 101 and a second surface 102, and mounting holes 103 with openings at both ends on the first surface 101 and the second surface 102, respectively.

[0075] The first seal 81 is adapted to abut against the wall of the first surface 101, the second surface 102 and the mounting hole 103. The pressure cap 7 is fixed to the protective shell 6 and abuts against one side of the fixing seat 3. The other side of the fixing seat 3 and the first surface 101 together clamp a part of the first seal 81, thereby preventing water from entering the mounting hole 103 between the fixing seat 3 and the first surface 101, causing water accumulation and damaging the product.

[0076] The protective shell 6 and the second surface 102 together clamp a portion of the first seal 81. Even if water enters the mounting hole 103 between the fixing seat 3 and the first surface 101 and then flows out from between the first seal 81 and the hole wall of the mounting hole 103, it will not be able to enter the area where the protective shell 6 is located due to the seal here, thus increasing the sealing performance.

[0077] The main body 11 of the drive unit 1 is installed inside the protective shell 6 for protection. The output shaft 12 of the drive unit 1 is adapted to pass through the mounting hole 103 to directly or indirectly move the massage component 2.

[0078] In one exemplary embodiment, the protective shell 6 is provided with a first through hole 61, the output shaft 12 of the drive member 1 is adapted to pass through the first through hole 61, and the pressure cap 7 is adapted to connect with the first through hole 61 to realize the installation of the pressure cap 7. Furthermore, the pressure cap 7 is adapted to clamp the second sealing member 82 together with the hole wall of the first through hole 61 to prevent water from entering the protective shell 6 from the connection between the pressure cap 7 and the first through hole 61, thus affecting the use of the drive member 1 inside the protective shell 6.

[0079] In one exemplary embodiment, the pressure cap 7 is provided with a second through hole 72, through which the output shaft 12 of the drive member 1 passes. The second through hole 72 and the output shaft 12 of the drive member 1 are adapted to jointly clamp the third seal 83 to prevent water from entering the protective shell 6 between the second through hole 72 and the output shaft 12, thereby affecting the use of the drive member 1 inside the protective shell 6.

[0080] In one exemplary embodiment, the third seal 83 is a V-shaped seal with a lip 831. The V-shaped seal facilitates dynamic sealing and has wear-resistant properties, making it suitable for sealing when the output shaft 12 rotates. The lip 831 faces a direction parallel to the first direction 9 and close to the massage component 2, which facilitates the output shaft 12 passing through the V-shaped seal and makes it easy to assemble the output shaft 12 with the V-shaped seal.

[0081] In one exemplary embodiment, the centerline of the massage section 211 does not coincide with the rotation axis of the output shaft 12, and extends obliquely in a direction away from the rotation axis of the output shaft 12, which can also increase the kneading area.

[0082] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
