Description

Technical Field

[0001] This utility model belongs to the field of home equipment technology, and relates to a foot bath device, and more particularly to a novel intelligent portable foot bath device. Background Technology

[0002] Traditional foot baths rely heavily on manual operation, requiring manual transport to a suitable location such as next to a sofa (or limited to bathroom use). During transport, the weight of the basin when full of water increases the user's physical burden, and the water is prone to spillage due to movement, significantly increasing the risk of slipping on wet floors, posing a serious safety hazard to the elderly and those with mobility impairments. Furthermore, existing foot baths with wheels lack dedicated anti-surge design, resulting in a high risk of spillage when moved fully loaded, also posing a safety hazard to those with mobility impairments. Moreover, existing foot baths rely on a fixed basin volume for water level adjustment, making dynamic adjustment impossible.

[0003] Therefore, in order to address the shortcomings of the existing technology, it is necessary to develop a new type of intelligent portable foot bath device. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model proposes a new type of intelligent portable foot bath device, which can reduce the amplitude of water sloshing when moving, eliminate the risk of overflow, and dynamically adjust the water level to adapt to the foot size and foot bath needs of different users.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel intelligent portable foot bath device includes a foot bath basin body.

A PTC ceramic heating element and an electric roller massage assembly are arranged on the inner bottom plate of the foot bath basin body. A control box is located at the rear exterior of the foot bath basin body. The control box contains a microcontroller, a micro air pump, and a deflation valve. The micro air pump and deflation valve are connected to the airbag assembly. The battery powers the PTC ceramic heating element, the electric roller massage assembly, the microcontroller, and the micro air pump.

[0006] Preferably, the wave-damping structure consists of 3-5 layers of annular wave-damping plates spaced apart along the height direction of the inner sidewall of the airbag assembly.

[0007] Preferably, the two annular wave deflectors are spaced 5-8 cm apart.

[0008] Preferably, the annular wave deflector is made of elastic silicone with a Shore hardness of 60-70, and the inner side of the annular wave deflector has multiple arc-shaped protrusions.

[0009] Preferably, the PTC ceramic heating element, the electric roller massage assembly, the micro air pump, and the vent valve are all connected to the microcontroller.

[0010] Preferably, a temperature sensor is also provided on the inner wall of the airbag assembly, and the temperature sensor is also connected to the microcontroller.

[0011] Preferably, the movable wheel includes two drive wheels and two omnidirectional wheels, the two drive wheels being driven by a motor, which is also connected to the microcontroller.

[0012] Preferably, the front end of the foot bath body is provided with an ultrasonic sensor and a lidar sensor connected to the microcontroller.

Secondly, the term "a" should be understood as "at least one" or "one or more," that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple. The term "a" should not be construed as a limitation on the quantity.

[0020] To address the shortcomings of existing technologies, this utility model provides a novel intelligent portable foot bath device. It can be moved to a location such as next to a sofa using wheels, making it relatively effortless. An innovative anti-wave structure reduces water sloshing during movement, eliminating the risk of overflow and ensuring safety. An innovative airbag assembly allows for dynamic water level adjustment of 15-25cm, accommodating over 90% of users' foot sizes and soaking needs.

[0021] like Figure 1-2 As shown, the novel intelligent portable foot bath device of this utility model includes a foot bath basin body 1. The bottom of the foot bath basin body 1 is equipped with casters 2 and a battery 5. By providing the casters 2, the foot bath basin body 1 can move on the ground, thereby saving physical effort in transporting it.

[0022] Preferably, the movable wheel 2 includes two drive wheels and two omnidirectional wheels. The two drive wheels are driven by a motor. The motor can be connected to the storage battery 5. Thus, driven by the motor, the foot bath body 1 can move automatically, making it very suitable for use by the elderly and people with mobility difficulties.

[0023] The foot bath body 1 has an airbag assembly 3 around its interior. The airbag assembly 3 can be inflated and deflated. The airbag assembly 3 is made of food-grade nitrile rubber with a thickness of 0.3 mm, and the airbag assembly 3 is fixed to the inner wall of the foot bath body 1 with waterproof adhesive.

[0024] A control box 6 is located on the external rear end of the foot bath body 1. The control box 6 contains a microcontroller, a micro air pump (5W power), and a vent valve. The vent valve can be a solenoid valve.

[0025] The miniature air pump and deflation valve are connected to the airbag assembly 3, and the battery 5 can power the miniature air pump. Thus, the miniature air pump inflates the airbag assembly 3, causing it to expand inward and compress the water, raising the water level in the novel intelligent portable foot bath device from 15cm (in the uninflated state of the airbag assembly 3) to a maximum of 25cm. Simultaneously, the deflation valve releases air from the airbag assembly 3, causing it to contract inward and lower the water level. Therefore, this invention, through its innovative airbag assembly, achieves dynamic water level adjustment of 15-25cm, adapting to the foot sizes and soaking needs of over 90% of users.

[0026] Both the micro air pump and the vent valve can be connected to the microcontroller, thereby enabling the microcontroller to control the activation of the micro air pump and the vent valve to achieve automatic adjustment of inflation / deflation and water level.

[0027] Meanwhile, in this utility model, the inner wall of the airbag assembly 3 is provided with a wave-damping structure 4.

[0028] Preferably, the wave-damping structure 4 consists of 3-5 layers of annular wave-damping plates spaced apart along the height of the inner wall of the airbag assembly 3. More preferably, the spacing between two annular wave-damping plates is 5-8 cm. Furthermore, the annular wave-damping plates are made of elastic silicone with a Shore hardness of 60-70, and the inner side of each annular wave-damping plate has multiple arc-shaped protrusions. Thus, the wave-damping structure 4 forms a "labyrinthine" water flow damping structure, which can disperse the lateral swaying impact force. Therefore, this invention, through its innovative wave-damping structure, can reduce the amplitude of water swaying during movement, eliminate the risk of overflow, and ensure safety.

[0029] Furthermore, in this invention, the inner bottom plate of the foot bath body 1 is provided with a PTC ceramic heating element 11 and an electric roller massage assembly 12. The battery 5 can power the PTC ceramic heating element 11, the electric roller massage assembly 12, and the microcontroller. Thus, the PTC ceramic heating element 11 can heat the water in the movable foot bath. And the electric roller massage assembly 12 can massage the feet.

[0030] Preferably, a temperature sensor is also provided on the inner wall of the airbag assembly 3, and the PTC ceramic heating element 11, the temperature sensor, and the electric roller massage assembly 12 are all connected to the microcontroller. Therefore, the microcontroller can control whether the PTC ceramic heating element 11 heats up based on the sensing result of the temperature sensor, achieving precise temperature control with an accuracy within ±1℃. Furthermore, the microcontroller can control the start and stop of the electric roller massage assembly 12.

[0031] It should be noted that any commercially available microcontroller can achieve the functions of this invention, and this invention does not impose any restrictions on the brand, model, etc. of the microcontroller.

[0032] Furthermore, in this invention, the front exterior of the foot bath body 1 is equipped with an ultrasonic sensor 9 and a lidar sensor 10 connected to the microcontroller. Simultaneously, existing navigation and obstacle avoidance software can be installed in the microcontroller. This software can use SLAM (Simultaneous Localization and Mapping) and the lidar sensor 10 for navigation, combined with the ultrasonic sensor 9, to perceive the surrounding environment in real time, construct a home map, and plan the optimal movement path. The ultrasonic sensor 9 can detect obstacles ahead, such as furniture and walls, ensuring the foot bath safely avoids them during movement. Therefore, automatic walking is possible, making it very suitable for the elderly and people with mobility impairments.

[0033] Finally, in this utility model, the top of the control box 6 is provided with a display screen 7 and buttons 8 connected to the microcontroller. The display screen 7 can display information such as water temperature. The buttons 8 may include ① a movement control button: triggering the automatic movement of the new intelligent movable foot bath device; ② an airbag assembly inflation button: a single press inflates for 5 seconds (water level rises by about 2cm), and a long press for 3 seconds to continue inflating to the highest water level; ③ an airbag assembly deflation button: a single press deflates for 5 seconds (water level drops by about 2cm), and a long press for 3 seconds to completely deflate to 15cm; ④ a massage start button: triggering the start and stop of the massage; ⑤ a temperature adjustment mode button: cycling through 3 water temperature levels (38℃ / 40℃ / 42℃).

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit the scope of protection of this utility model. Those skilled in the art can modify or make equivalent substitutions to the technical solution of this utility model based on the concept of this utility model, without departing from the essence and scope of the technical solution of this utility model.
