Description

Technical Field

[0001] This application relates to the field of bathing equipment technology, and more particularly to a multifunctional bathtub. Background Technology

[0002] Currently, the main function of conventional bathtubs on the market is to soak in the bath. Although some products are equipped with fixed shower heads to achieve basic cleaning, their overall functions are relatively simple and cannot meet users' comprehensive needs for cleanliness, relaxation and convenience during the bathing process.

[0003] Specifically, existing bathtubs have several shortcomings: First, they lack integrated massage functions. The few products with massage components often have fixed structures, making it impossible to flexibly adjust their position to suit different users' scalp or body massage needs. Furthermore, some rotating massage components are prone to tangling hair, affecting safety and comfort. Second, in winter, users need to rely on external towels to dry themselves after bathing, as the bathtub lacks a built-in drying device, making them susceptible to catching a cold due to temperature differences, resulting in a poor experience. Third, water level control in the bathtub relies on manual monitoring, which can easily lead to overflow. Additionally, residual water in the tub after bathing is difficult to dry quickly, and long-term use can easily breed bacteria, affecting hygiene. Fourth, even if some bathtubs have water spray and massage functions, the two are difficult to synchronize and coordinate, making it impossible to spray warm water specifically onto the massage area during the massage process, resulting in a disconnect between cleaning and relaxation effects.

[0004] The aforementioned problems limit the user experience of conventional bathtubs, necessitating a more advanced bathtub product that integrates multiple functions, offers flexible adjustments, ensures safety and hygiene, and provides a superior user experience to address the shortcomings of existing technology.

[0019] In the above embodiment, the multifunctional bathtub consists of a bathtub body 100 and a universal arm assembly 200 with a massage mechanism 400 and a shower head 300. During bathing, the position of the massage mechanism 400 can be adjusted through the universal arm assembly 200. The turntable 410 of the massage mechanism 400 is placed next to the head. After the power of the drive motor 446 is turned on, the output shaft of the drive motor 446 rotates and drives the turntable 410 to rotate slowly around the output shaft of the drive motor 446. Since the surface of the turntable 410 is provided with several protrusions 420, the protrusions 420 massage the scalp. The universal arm assembly 200 can precisely adjust the position of the massage mechanism 400. The drive motor 446 drives the turntable 410 to rotate slowly, and the protrusions 420 can specifically massage the scalp. Moreover, massage and bathing can be carried out simultaneously, improving the convenience and comfort of use, and making the bathing process have both cleaning and relaxation effects, resulting in a richer user experience. Example

[0020] Please see Figures 1 to 5 The bathtub body 100 is provided with a semi-egg-shaped guard plate 110 on the side away from the universal arm assembly 200. The bottom end of the semi-egg-shaped guard plate 110 is connected to the edge of the opening of the bathtub body 100, and the connection is smoothly transitioned. The concave surface of the semi-egg-shaped guard plate 110 faces the universal arm assembly 200. Multiple bathroom heater lights 120 are installed on the side of the semi-egg-shaped guard plate 110 near the universal arm assembly 200.

[0021] In the above embodiment, to enhance the aesthetics of the bathtub body 100, a semi-eggshell-shaped guard plate 110 is installed at the end of the bathtub body 100 away from the universal arm assembly 200, which is also the end closer to the feet. The semi-eggshell-shaped guard plate 110 is approximately a quarter of an eggshell, with the opening of the eggshell facing the universal arm assembly 200, and the edge of the eggshell has a wave-shaped decorative pattern. In addition to enhancing the aesthetics of the bathtub body 100, multiple bathroom heater lamps 120 are also installed on the concave surface of the semi-eggshell-shaped guard plate 110. After bathing, the bathroom heater lamps 120 can be turned on to dry the skin, improving the bathing experience in winter. The bathroom heater lamps 120 are insulated. Example

[0022] Please see Figures 1 to 5 The bathtub body 100 is also provided with a plurality of overflow holes 130 near the opening; a plurality of fans 140 are also installed on the inner wall of the bathtub body 100 above the overflow holes 130.

[0023] In the above embodiment, the overflow hole 130 is located below the fan 140. The fan 140 is waterproof and insulated. The overflow hole 130 is used to prevent the water level from submerging the fan 140. After bathing, the fan 140 can be used to dry the skin, or the fan 140 can be turned on to dry the bathtub body 100, thus improving the problem of bacteria growth caused by a large amount of water remaining in the bathtub body 100. Example

[0024] Please see Figures 1 to 5 The universal arm assembly 200 includes: a friction-damped spherical universal shaft 210, with a mounting base installed on the edge of the opening of the bathtub body 100; a first connecting rod 220, one end of which is connected to the end of the friction-damped spherical universal shaft 210 away from the mounting base; and a second connecting rod 230, one end of which is hinged to the other end of the first connecting rod 220, and the other end of which is used to install the shower head 300 and the massage mechanism 400; both the first connecting rod 220 and the second connecting rod 230 are hollow structures, and the hollow cavities inside the first connecting rod 220 and the second connecting rod 230 are used for water flow; the end of the first connecting rod 220 away from the second connecting rod 230 is connected to a water supply hose 240, and the other end of the water supply hose 240 is connected to a faucet.

[0025] In the above embodiments, the friction-damped spherical universal joint 210 is used to fix the adjusted position of the universal arm assembly 200 by means of the damping sensation of the universal joint itself. The friction-damped spherical universal joint 210 is a commonly used device, so it will not be described in detail here. During the adjustment process, the massage mechanism 400 is dragged and the end of the second link 230 is moved. The second link 230 swings around the first link 220. At this time, the first link 220 is pulled by the second link 230, so that the end of the first link 220 away from the second link 230 swings around the spherical universal joint, thereby achieving the purpose of multi-point adjustment of the massage mechanism 400. Example

[0026] Please see Figures 1 to 5 The massage mechanism 400 includes: a mounting plate 430 disposed on the end wall of the second connecting rod 230; multiple connecting rod mechanisms 440 arranged in a ring array along the outer periphery of the mounting plate 430; each connecting rod mechanism 440 includes: an extension plate 441, one end of which is connected to the edge of the mounting plate 430, and the other end which is inclined towards the side of the mounting plate 430 away from the second connecting rod 230; finger-shaped massage heads 442 spaced apart at the end of the extension plate 441; a third connecting rod 443 and a fourth connecting rod 444, both ends of which are respectively hinged to the finger-shaped massage heads 442 and the extension plate 441; The third link 443 is arranged parallel to the fourth link 444; the fifth link 445 is hinged to the third link 443 at one end; the drive disk 448 is spaced apart on one side of the mounting plate 430, and the other end of each fifth link 445 is respectively hinged to the edge of the drive disk 448; the drive motor 446 is mounted on the surface of the mounting plate 430; the screw 447 is connected to the drive motor 446 at one end, and the other end passes through the center of the drive disk 448 and is threadedly connected to the drive disk 448; the turntable 410 is mounted on the end of the screw 447 away from the drive motor 446.

[0027] In the above embodiment, when the massage mechanism 400 is close to the head, the drive motor 446 is started. The output shaft of the drive motor 446 rotates, driving the screw 447 to rotate. When the screw 447 rotates, it drives the turntable 410 to rotate. The protrusions 420 provided on the inner wall of the turntable 410 massage the scalp. In order to drive the finger-shaped massage head 442 to fit against the scalp and rub the scalp back and forth, the drive motor 446 needs to rotate forward and reverse intermittently. When the output shaft of the drive motor 446 rotates forward and reverse intermittently, the turntable 410 rotates forward and reverse intermittently, so that the protrusions 420 on the turntable 410 will not cause hair to become excessively wrapped around the protrusions 420 on the turntable 410 during the forward and reverse rotation of the output shaft of the drive motor 446. When the output shaft of the drive motor 446 rotates intermittently in both directions, the screw 447 drives the drive disk 448 to reciprocate on the screw 447, causing the drive disk 448 to intermittently move closer to or away from the mounting plate 430. During the movement of the drive disk 448, one end of the fifth link 445 moves, causing the other end of the fifth link 445 to push the third link 443 closer to its central position. This causes the third link 443 and the fourth link 444 to swing around their hinge with the extension plate 441, causing the other ends of the third link 443 and the fourth link 444 to synchronously drive the finger-shaped massage head 442 to contract or expand. Then, the scalp is massaged by the continuously contracting and expanding finger-shaped massage heads 442. Example

[0028] Please see Figures 1 to 5 The shower head 300 includes: a basin-shaped body 310 disposed between the mounting plate 430 and the drive disc 448; a mounting hole 320 disposed at the center of the surface of the basin-shaped body, the mounting hole 320 being used to install the drive motor 446; a cavity provided inside the basin-shaped body 310, the cavity communicating with the interior of the hollow second connecting rod 230; and a plurality of spray holes 330 provided in the concave surface of the basin-shaped body 310, the spray holes 330 being arranged in a ring array in the region of the basin-shaped body 310 near the outer side of the drive disc 448.

[0029] In the above embodiment, the concave surface of the basin-shaped body faces the turntable 410, and the water spray holes 330 provided on its surface face the turntable 410. The water spray holes 330 are arrayed in the outer area of ​​the turntable 410, so that the water jet from the water spray holes 330 can reach the scalp through the drive plate 448 and the turntable 410. During the massage, warm water can be continuously sprayed onto the scalp area through the water spray holes 330.

[0030] The various embodiments in this specification are described in a progressive manner. For the same or similar parts between the various embodiments, please refer to each other. Each embodiment focuses on describing the differences from other embodiments.

[0031] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
