Description

Technical Field

[0001] This utility model relates to the field of foot bath technology, and in particular to a foot bath with sterilization function. Background Technology

[0002] With the improvement of people's living standards and the enhancement of health awareness, foot baths, as a traditional health preservation method, have gained increasing popularity. Foot bath devices, as household appliances that enable foot baths, are also gradually entering more and more homes. Modern foot bath devices not only have basic functions such as heating and massage, but are also developing towards greater intelligence and multi-functionality to meet the increasingly diverse needs of consumers. During a foot bath, the water in the foot bath device is in contact with the user's feet for a long time, and bacteria and dirt from the foot skin can enter the water, causing the water quality to gradually deteriorate. If foot baths are performed with water that has not been effectively sterilized for a long time, not only will the desired health benefits not be achieved, but it may also cause skin infections, allergies, and other health problems. Therefore, ensuring the cleanliness and hygiene of the water in the foot bath device has become a key consideration in the design and manufacturing process. Currently, most foot bath devices on the market use water circulation systems to achieve water resource recycling and conserve water. A water circulation system typically consists of a water generator, circulation pipes, and a water outlet. The water generator draws water from the foot bath, transports it through the circulation pipes to the water outlet, and then sprays it onto the user's feet, creating a circulation. However, existing water circulation systems often lack effective sterilization devices, or the sterilization effect of the devices is unsatisfactory, failing to effectively kill bacteria, viruses, and other harmful microorganisms in the water, making it difficult to guarantee the hygiene and safety of the foot bath water.

[0003] Existing foot baths with sterilization functions suffer from inadequate layout and design of their sterilization devices. Many products' sterilization devices fail to comprehensively and effectively sterilize the water in the circulating water path, leaving sterilization blind spots. This allows some microorganisms to survive and multiply in the water, failing to truly guarantee the hygiene and safety of the foot bath water. Furthermore, some sterilization devices are poorly coordinated with the water flow, affecting sterilization efficiency and water circulation, thus reducing the overall performance of the foot bath. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a foot bath device with sterilization function.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A foot bath device with sterilization function, the foot bath device includes a main body forming a foot bath cavity inside and a cover covering the main body, the foot bath device further includes: A water outlet disposed on the cover, a water flow generator disposed on the main body, and a circulation pipe for connecting the water flow generator and the water outlet, the water flow generator being configured to drive water to flow towards the cover; and A light-based sterilization device is disposed on the cover and positioned downstream of the circulation pipe in the direction of water flow to sterilize and disinfect the water in the circulation pipe. The circulation pipeline includes a sterilization section, and the light sterilization device is configured to irradiate the sterilization section directly, with the light direction of the light sterilization device being opposite to the water flow direction.

[0006] Furthermore, the circulation pipeline is configured to extend from the foot bath cavity toward the cover.

[0007] Furthermore, the length of the sterilization section is at least 2.5 cm to increase the sterilization range of the sterilization device.

[0008] Furthermore, the circulation pipeline is configured to extend from the foot bath cavity toward the cover, and the sterilization section is one of the vertical sections.

[0009] Furthermore, the circulation pipe is a flexible pipe, and the foot bath has a path defining member adapted to guide the extension path of the circulation pipe to form the vertical section.

[0010] Furthermore, the path defining member includes a straight wall portion, the interior of which forms a defining space for defining the shape of the vertical segment.

[0011] Furthermore, a guiding component is disposed inside the circulation pipeline, the guiding component being configured to extend the sterilization time by extending the water flow path.

[0012] Furthermore, the circulation pipeline is also equipped with a water outlet, and the guiding component divides the circulation pipeline into a first cavity section and a second cavity section. The first cavity section is configured as part of the sterilization section, and the second cavity section is adapted to be connected to the water outlet.

[0013] Furthermore, the guide member is configured to extend upward from the bottom end of the water inlet, and the top end of the guide member is higher than the top end of the water inlet.

[0014] Furthermore, the sterilization device is an ultraviolet sterilization device, which includes a mounting frame and an ultraviolet lamp, wherein the ultraviolet lamp is configured to irradiate ultraviolet light onto the first cavity segment.

[0015] Furthermore, the circulation pipeline also includes a transfer pipe having a water inlet extending in a vertical direction and a water outlet extending in a horizontal direction, the water outlet being disposed in the water outlet and the guide member being disposed in the water inlet.

[0016] Due to the adoption of the above technical solutions, this utility model has the following beneficial effects: 1. This utility model rationally configures the sterilization device on the cover, placing it downstream of the circulation pipeline. The circulation pipeline includes a sterilization section, with the ultraviolet sterilization device directly facing this section, and the ultraviolet light propagating in the opposite direction to the water flow. This unique layout ensures that the water in the circulation path receives sufficient ultraviolet radiation during flow, avoiding sterilization dead zones. Furthermore, regarding the synergy between sterilization efficiency and water circulation, this patented design achieves perfect coordination between the sterilization device and the water flow. The opposite direction of ultraviolet light propagation ensures that microorganisms in the water are continuously irradiated by ultraviolet light during flow, extending the sterilization time and improving sterilization efficiency.

[0017] 2. The circulation pipe of this utility model extends from the foot bath cavity towards the cover, and the sterilization section is designed as a vertical section with a length of at least 2.5cm. This design increases the sterilization range of the sterilization device, allowing the water to receive more time and space for ultraviolet irradiation when passing through the vertical sterilization section, thereby more effectively killing bacteria, fungi, and other microorganisms in the water, significantly improving the hygiene and safety level of the foot bath water, and providing stronger protection for the user's foot health.

[0018] 3. The path-limiting component of this utility model extends the sterilization time by lengthening the water flow path. During the water circulation process, the path-limiting component prevents the water flow from passing directly and quickly, but instead causes it to flow in a detour along a specific path, increasing the residence time of the water flow in the sterilization area and giving ultraviolet rays more opportunities to kill microorganisms. The circulation pipeline uses flexible components, which, together with the path-limiting component, guide its extension path to form a vertical sterilization section. Attached Figure Description

[0032] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0033] Please see Figures 1-7This utility model discloses a foot bath device with sterilization function. The foot bath device includes a main body 100, a cover 120, a water circulation system 200, and a light sterilization device 240. The main body 100 has a foot bath cavity 111 formed inside. The cover 120 is placed on the main body 100 to seal the foot bath cavity 111 when not in use, preventing dust and other debris from entering. The water circulation system 200 includes a water outlet 210, a water flow generator 220, and a circulation pipe 230. The water outlet 210 is disposed on the cover 120, the water flow generator 220 is disposed on the main body 100, and the circulation pipe 230 connects the water flow generator 220 and the water outlet 210. The water flow generator 220 is configured to drive water to flow towards the cover 120. In this embodiment, the water flow generator 220 can be a water pump, which draws water from the foot bath cavity 111, pressurizes the water, and delivers it through the circulation pipe 230 to the outlet 210 on the cover 120, thereby achieving water circulation. A light sterilization device 240 is disposed on the cover 120, downstream of the circulation pipe 230 in the water flow direction, to sterilize the water within the circulation pipe 230. Specifically, the light sterilization device 240 is an ultraviolet sterilization device. The circulation pipe 230 includes a sterilization section 231, and the ultraviolet sterilization device is configured to irradiate the sterilization section 231 directly, with the ultraviolet light propagating in the opposite direction to the water flow. This arrangement allows the ultraviolet light to move in opposite directions to the water flow, increasing the contact time between the ultraviolet light and the water flow, thereby improving the sterilization effect. In this embodiment, the length of the sterilization section 231 is at least 2.5 cm to increase the sterilization range of the light sterilization device 240. Experiments have shown that when the length of the sterilization section 231 is 2.5cm, the ultraviolet sterilization device can effectively irradiate the water flow inside the pipe, achieving a sterilization rate of over 90%. When the length of the sterilization section 231 is increased to 3cm, the sterilization rate can be further improved to over 95%. Therefore, setting the length of the sterilization section 231 to at least 2.5cm is reasonable and can meet the sterilization needs of daily foot baths. The circulation pipe 230 is configured to extend from the foot bath chamber 111 towards the cover 120, with the sterilization section 231 being a vertical section within it. This configuration allows the water flow to be vertical, opposite to the direction of ultraviolet light propagation, further increasing the interaction time between the ultraviolet light and the water flow. Simultaneously, the vertical section also facilitates smooth water flow and reduces water flow resistance.

[0034] In this embodiment, the circulation pipe 230 is a flexible pipe, and the foot bath has a path-limiting member 400, which is adapted to guide the extension path of the circulation pipe 230 to form a vertical section. Specifically, the path-limiting member 400 includes a straight wall portion 410 and a curved wall portion 420 extending downward from the straight wall portion 410. The straight wall portion 410 has a limiting space inside to define the shape of the vertical section. The curved wall portion 420 is configured to guide the circulation pipe 230 to produce a bending deformation to form a curved section 232, thereby avoiding the bottom device. The bottom device may include part of the structure of the water flow generator 220, other components within the main body 100, etc. Guided by the curved wall portion 420, the circulation pipe 230 can smoothly bypass these bottom devices, avoiding interference and ensuring the normal operation of water circulation.

[0035] like Figure 5 , Figure 6 The circulation pipe 230 is internally equipped with a guiding member 233, which is configured to extend the water flow path to prolong the sterilization time. The circulation pipe 230 also has a water inlet 2521. The guiding member 233 divides the circulation pipe 230 into a first cavity section 411 and a second cavity section 412. The first cavity section is configured as part of the sterilization section 231, and the second cavity section is adapted to connect to the water inlet 2521. The guiding member 233 is configured to extend upward from the bottom end of the water inlet 2521, and the top end of the guiding member 233 is higher than the top end of the water inlet 2521. This arrangement ensures that after the water flows into the circulation pipe 230, it first passes through the first cavity section 411. Due to the obstruction of the guiding member 233, the water flow must bypass the top end of the guiding member 233 before entering the second cavity section 412, thereby prolonging the flow path of the water within the sterilization section 231, increasing the sterilization time, and improving the sterilization effect. The circulation pipe 230 also includes a connecting pipe 250, which has a vertically extending inlet 251 and a horizontally extending outlet 252. A water inlet 2521 is disposed on the outlet 252, and a guide member 233 is disposed on the inlet 251. The outlet 252 is connected to the outlet 210. The connecting pipe 250 allows for better connection between the circulation pipe 230 and the outlet 210, and also facilitates the installation and positioning of the guide member 233. The water circulation system 200 also includes a water outlet component 260, with a water outlet 210 disposed on the water outlet component 260. The water outlet component 260 can be a nozzle structure, which can spray sterilized water at a certain pressure and angle to rinse and massage the user's feet, thereby improving the comfort of the foot bath. The transfer pipe 250 also includes a positioning part 253. The photo-sterilization device 240 is positioned in the positioning part 253 by irradiating ultraviolet light in a vertical direction. The positioning part 253 is sealed to the cover 120 by a sealing ring 300. The sealing ring 300 ensures the airtightness between the positioning part 253 and the cover 120, preventing water leakage from the connection. At the same time, the positioning part 253 also ensures that the photo-sterilization device 240 can accurately irradiate the sterilization section 231, ensuring the sterilization effect. The photo-sterilization device 240 includes a mounting bracket 241 and an ultraviolet lamp 242, which is configured to irradiate ultraviolet light onto the first cavity segment 411. The mounting bracket 241 is used to fix the ultraviolet lamp 242 on the positioning part 253 to ensure the stability of the position of the ultraviolet lamp 242 and prevent the irradiation position from shifting due to vibration or other reasons. The working process of this utility model will be further described below. When the user uses the foot bath device, firstly, an appropriate amount of water is added to the foot bath cavity 111 of the main body 100, then the cover 120 is closed, and the water flow generator 220 and the light sterilization device 240 are turned on. The water flow generator 220 starts working, drawing water from the foot bath cavity 111 into the circulation pipe 230 and driving the water to flow towards the cover 120. When the water flows in the circulation pipe 230, it first passes through the curved section 232, and under the guidance of the curved wall portion 420, it bypasses the bottom device, and then enters the vertical section defined by the straight wall portion 410, namely the sterilization section 231. In the sterilization section 231, the ultraviolet rays emitted by the ultraviolet lamp 242 irradiate the first cavity section 411. Since the direction of ultraviolet light propagation is opposite to the direction of water flow, and the guiding member 233 extends the water flow path, the water can be fully irradiated by ultraviolet rays in the first cavity section 411, thereby achieving sterilization and disinfection. The sterilized water continues to flow, passing through inlet 2521 into the second chamber 412, then through the outlet 252 of the adapter pipe 250 into the outlet component 260, and finally spraying out from outlet 210 to rinse and massage the user's feet. The sprayed water eventually flows back into the foot bath chamber 111, forming a water circulation, thereby achieving continuous sterilization, disinfection, and foot bath functions. In this invention, by placing the photo-sterilization device 240 downstream of the circulation pipe 230 and using an ultraviolet sterilization device to irradiate the sterilization section 231 directly, with the ultraviolet light propagating in the opposite direction to the water flow, the sterilization effect can be effectively improved. Simultaneously, the length of the sterilization section 231, the path design of the circulation pipe 230, and the placement of the guiding component 233 further enhance the sterilization effect, ensuring the hygiene and safety of the foot bath water. Furthermore, the foot bath device has a reasonable structural design, with tight fit between all components, enabling stable and reliable operation and providing users with a comfortable and hygienic foot bath experience.

[0036] It should be noted that the circulation pipe 230 in this invention can be made of transparent or semi-transparent material to facilitate the penetration of ultraviolet rays and improve the sterilization effect. At the same time, the inner wall of the circulation pipe 230 can be smoothed to reduce water flow resistance, prevent water from forming eddies or stagnation in the pipe, ensure smooth water flow, and thus improve the uniformity of sterilization. In other embodiments of this invention, the length of the sterilization section 231 can be adjusted according to actual needs, as long as it is not less than 2.5 cm. For example, when a higher sterilization rate is required, the length of the sterilization section 231 can be appropriately increased, such as to 3 cm or 4 cm. The shape and structure of the path limiting component 400 can also be adjusted according to the specific position and shape of the bottom device to ensure that the circulation pipe 230 can smoothly avoid the bottom device while forming the required sterilization section 231. The shape and size of the guiding component 233 can also be optimized to better extend the water flow path and improve the sterilization effect.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
