Description

Technical Field

[0001] This utility model relates to the field of health, specifically to a foot bath device. Background Technology

[0002] Existing foot bath devices include a shell with an internal foot bath cavity. At the bottom of the shell are a steam generation component, a thermopressing component, and a massage component. Steam generated by the steam generation component is processed by the thermopressing component and then sprayed outwards through the massage component to provide massage stimulation. The thermopressing component extracts the steam generated by the steam generation component, heats and pressurizes it, and then delivers it to the massage component. The massage component includes multiple dispersed massage heads. Because the distance between each massage head and the thermopressing component varies, and the steam pressure decreases as the transmission distance increases, the steam pressure sprayed outwards from each massage head varies. This results in variations in the intensity of the massage stimulation generated by the steam spray, reducing massage comfort and affecting the user experience. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a foot bath device with uniform water vapor spray. By setting a diversion plate with a diversion channel between the massage head and the hot pressing component, the water vapor pressure is changed by utilizing the change in the cross-sectional area of ​​the diversion channel. This ensures that the water vapor still has a large pressure after long-distance transportation, thereby ensuring the intensity of massage stimulation and improving the user experience.

[0004] This invention achieves its purpose through the following method: a foot bath device with uniform water vapor spray, comprising a shell containing a foot bath cavity, a partition plate at the bottom of the shell, a water vapor generating component located at the partition plate, a thermopressing component located below the partition plate, and a massage component located above the partition plate. Water vapor generated by the water vapor generating component is processed by the thermopressing component and then sprayed outwards through the massage component to create massage stimulation. The massage component includes several separately positioned massage heads. The thermopressing component is connected to each massage head via a diversion plate with a diversion channel. The diversion channel has an inlet communicating with the thermopressing component. The cross-sectional area of ​​each section of the diversion channel decreases as the distance from the inlet increases to maintain the pressure when water vapor is input to the corresponding massage head. By setting a diversion plate with a diversion channel between the massage head and the thermopressing component, the diversion channel increases the water vapor pressure by reducing its cross-sectional area, ensuring that the water vapor maintains a high pressure after long-distance transportation, thereby ensuring that the water vapor sprayed by each massage head can produce a uniform massage stimulation intensity and improve the user experience. The partition plate serves to fix and position the steam generation component, the hot pressing component, and the massage component. It also forms the bottom wall of the foot bath cavity, providing insulation and protection for the hot pressing component below.

[0005] Preferably, the diversion channel is H-shaped, including two separate secondary channels and a main channel spanning the middle of the secondary channels. The inlet is located in the middle of the main channel, and the massage heads are arranged along the secondary channels to reduce the distance between the inlet and each massage head. The main channel receives water vapor from the inlet and delivers it to each secondary channel. The secondary channels connect adjacent massage heads, which effectively simplifies the structure of the diversion channel, facilitates manufacturing, and effectively reduces the distance between the inlet and each massage head, thereby reducing water vapor pressure loss by shortening the water vapor delivery length.

[0006] Preferably, the radial cross-sectional area of ​​each section of the secondary channel gradually decreases from the middle to both ends to increase the water vapor pressure. Under the same water vapor flow rate, the smaller the radial cross-sectional area of ​​each section of the secondary channel, the greater the water vapor pressure. By increasing the water vapor pressure, the pressure loss during the water vapor transportation process is offset, ensuring that the water vapor has the pressure required for use when it reaches the corresponding massage head.

[0007] Preferably, the cross-sectional profiles of each section of the main channel are identical, so that water vapor is evenly distributed to the secondary channels on both sides. The flow resistance at both ends of the main channel is the same, and the water vapor received through the inlet can be evenly distributed to the secondary channels at both ends, ensuring that each secondary channel receives an equal amount of water vapor.

[0008] Preferably, the junction between the secondary channel and the main channel is rounded, so that the cross-sectional area between adjacent sections of the diversion channel gradually changes. By setting the rounded corners, the resistance to water vapor flow is reduced, which not only effectively reduces pressure loss, but also ensures that the cross-sectional area at the junction of the main channel and the secondary channel changes gradually, preventing sudden and large changes in water vapor pressure.

[0009] Preferably, the secondary channel is equipped with at least two massage heads, each containing a nozzle that guides water vapor outwards. The nozzle receives water vapor from the secondary channel and sprays it outwards. By providing multiple massage heads, multiple massage stimuli can be delivered to the user's feet, enhancing massage comfort and ensuring that each area of ​​the user's feet receives massage stimulation from the corresponding massage head.

[0010] Preferably, the secondary channel is equipped with three separate massage heads, which simplifies the structure, facilitates production and assembly, and ensures that all areas of the foot can receive massage stimulation.

[0011] Preferably, the lower end of the nozzle is connected to the diversion channel, and the upper end is connected to the foot bath cavity through multiple upward-facing nozzles. The nozzle receives water vapor from the diversion channel and sprays it into the foot bath cavity through the nozzles. Multiple parallel nozzles are provided, with nozzles on the same massage head connected to the same nozzle. This not only creates multiple water vapor jets and thus multiple massage stimuli, but also increases the water vapor jet pressure by reducing the nozzle diameter, ensuring that the intensity of each massage stimulation meets the usage requirements.

[0012] Preferably, the top wall of the diversion channel has mounting holes, and the bottom of the massage head is inserted into the corresponding mounting holes to connect the nozzle to the diversion channel. The mounting holes are used to fix the massage head, ensuring that the massage head is in a fixed position and facilitating the connection between the bottom of the massage head and the diversion channel. This allows the lower end of the nozzle to receive water vapor from the diversion channel, providing the user with continuous and effective massage stimulation.

[0013] Preferably, the steam generation component is disposed in the atomizing tank at the bottom of the foot bath cavity. The thermostatic component includes a pump body and a first heating element. The pump body draws steam generated in the atomizing tank and, after flowing through the first heating element, forms high-temperature steam that is delivered to the diversion channel. The atomizing tank contains a water source, which is converted into steam by the steam generation component. The pump body draws water from the water source and, after increasing the pressure, flows through the first heating element, so that the steam forms high-temperature steam that meets the pressure and temperature requirements and is delivered to the massage component through the diversion channel.

[0014] Preferably, the water vapor generation component includes an ultrasonic atomizer, through which water in the atomization tank is atomized into water vapor. The ultrasonic atomizer atomizes the water source into water vapor, providing water vapor for both the hot-pressing component and the foot bath cavity with adjustable temperature water vapor.

[0015] Preferably, the water vapor generating component includes a second heating element that heats the water source. The second heating element heats the water source in the atomizing tank so that the water vapor temperature reaches the required temperature inside the foot bath cavity.

[0016] The beneficial effects of this utility model are as follows: By setting a diversion plate with a diversion channel between the massage head and the hot pressing component, the diversion channel increases the water vapor pressure by reducing the cross-sectional area, ensuring that the water vapor still has a large pressure after long-distance transportation, thereby ensuring that the water vapor sprayed by each massage head can produce a uniform massage stimulation intensity and improve the user experience.

[0024] The essential features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1 and 2 The foot bath device shown includes a shell 1 with an internal foot bath cavity. The bottom of the shell 1 is provided with a partition plate 13, a water vapor generating component 14 located at the partition plate 13, a heat pressing component 2 located below the partition plate 13, and a massage component 3 located above the partition plate 13. The water vapor generated by the water vapor generating component 14 is processed by the heat pressing component 2 and then sprayed outward through the massage component 3 to form a massage stimulation. The massage component 3 includes several separately placed massage heads 4. The heat pressing component 2 is connected to each massage head 4 through a diversion plate 5 with a diversion channel 6. The diversion channel 6 is provided with an inlet 7 communicating with the heat pressing component 2. The cross-sectional area of ​​each section of the diversion channel 6 decreases as the distance between it and the inlet 7 increases, so as to maintain the pressure when water vapor is input to the corresponding massage head 4. By setting a diversion plate 5 with a diversion channel 6 between the massage head 4 and the hot pressing assembly 2, the diversion channel 6 increases the water vapor pressure by reducing the cross-sectional area, ensuring that the water vapor still has a large pressure after long-distance transportation, thereby ensuring that the water vapor sprayed by each massage head 4 can produce a uniform massage stimulation intensity and improve the user experience.

[0026] In actual operation, the diversion channel 6 includes a main channel 9 and a secondary channel 8. The main channel 9 connects the input port 7 and the secondary channel 8, while the secondary channel 8 connects multiple massage heads 4 simultaneously. The radial cross-sectional area of ​​each section of the secondary channel 8 gradually decreases from the middle to both ends to increase the water vapor pressure. The massage heads 4 are distributed on the secondary channel 8. The radial cross-sectional area of ​​each section of the secondary channel 8 is different, with the largest radial cross-sectional area in the section connecting the secondary channel 8 and the main channel 9. The radial cross-sectional area of ​​each section of the secondary channel 8 gradually decreases as it extends towards both ends. By reducing the radial cross-sectional area of ​​the secondary channel 8, the water vapor pressure is increased, thereby compensating for the pressure loss caused by long-distance water vapor transportation. This ensures that each massage head 4 distributed on the secondary channel 8 receives water vapor with balanced pressure, guaranteeing that the water vapor sprayed by each massage head 4 onto the user's feet forms a uniform massage stimulation intensity, effectively improving massage comfort.

[0027] In actual operation, the diversion channel 6 is H-shaped (e.g., Figure 3 As shown, the device includes two separate secondary channels 8 and a main channel 9 spanning the middle of the secondary channels 8. The input port 7 is located in the middle of the main channel 9, and the massage heads 4 are arranged along the secondary channels 8 to reduce the distance between the input port 7 and each massage head 4. There are two secondary channels 8, located at both ends of the main channel 9, so that the secondary channels 8 and the massage heads 4 on them correspond to the user's feet. The massage heads 4 on a single secondary channel 8 are arranged in a straight line, which facilitates the application of massage stimulation to the corresponding feet of the user. The ends of the main channel 9 are located in the middle of the corresponding secondary channels 8 to ensure that the distance between the input port 7 and each port of each secondary channel 8 is balanced, preventing excessive water vapor pressure loss due to excessive distance between the massage heads 4 and the input port 7.

[0028] In actual operation, the cross-sectional profiles of each section of the main channel 9 are the same, so that water vapor is evenly distributed to the secondary channels 8 on both sides, thereby ensuring that each secondary channel 8 can obtain an equal amount of water vapor and preventing insufficient pressure due to insufficient water vapor flow.

[0029] In actual operation, the connection between the secondary channel 8 and the main channel 9 is achieved through a fillet 10, so that the cross-sectional area between adjacent sections of the diversion channel 6 gradually changes. The end of the main channel 9 is connected to the middle of the secondary channel 8, and the corresponding walls are connected through a fillet 10. This reduces wind resistance and thus pressure loss, and also reduces the pressure variation by gradually changing the cross-sectional area at the connection, thereby ensuring that water vapor is effectively and uniformly transported.

[0030] In actual operation, the secondary channel 8 is equipped with at least two massage heads 4. Each massage head 4 has a nozzle 11 that guides water vapor to be sprayed outward. The nozzle 11 receives water vapor from the secondary channel 8 and sprays it outward. Specifically, the secondary channel 8 is equipped with three separately positioned massage heads 4, located at both ends of the middle section of the secondary channel 8. The massage heads 4 located in the middle section of the secondary channel 8 are closer to the inlet 7, allowing water vapor to be sprayed outward at higher pressure and with a larger flow rate. The massage heads 4 located at the ends of the secondary channel 8 are further apart from the inlet 7, requiring the water vapor to be squeezed through the gradually narrowing secondary channel 8 to increase the pressure, ensuring that the water vapor spray pressure meets the usage requirements.

[0031] In actual operation, the lower end of the nozzle 11 is connected to the diversion channel 6, and the upper end is connected to the foot bath cavity through multiple upward-facing nozzles 20. The nozzle 11 receives water vapor from the diversion channel 6 and sprays it into the foot bath cavity through the nozzles 20. An installation hole 12 (e.g., ...) is provided on the top wall of the diversion channel 6. Figure 4 As shown), the bottom of the massage head 4 is inserted into the corresponding mounting hole 12 so that the nozzle 11 communicates with the diversion channel 6. The mounting hole 12 is opened on the top wall of the secondary channel 8. The massage head 4 includes a mounting base 21 and a massage cover 22 (as shown). Figure 6 As shown, the mounting base 21 is sealed and inserted into the mounting hole 12 at the bottom, and its top is sealed and covered by the massage cover 22. Both the massage cover 22 and the mounting base 21 are hollow structures, connected to form the nozzle 11. The top surface of the massage cover 22 has a nozzle 20 communicating with the nozzle 11. The lower end of the nozzle 11 is opened on the bottom surface of the mounting base 21, so that the nozzle 11 is connected to the secondary channel 8 and provides the water vapor required for spraying to the nozzle 20. In addition, the top surface of the massage cover 22 has massage protrusions. The massage cover 22 rotates and drives the massage protrusions to apply a pressing force to the user's feet, which can also form a massage stimulation.

[0032] In actual operation, the water vapor generating component 14 is installed in the atomizing groove 15 at the bottom of the foot bath cavity. The water vapor generating component 14 includes an ultrasonic atomizer 16 and a second heating element 17 (such as...). Figure 5 As shown, the water source in the atomizing tank 15 is atomized into water vapor by the ultrasonic atomizer 16, and the second heating element 17 heats the water source. The water source in the atomizing tank 15 is heated to a preset temperature by the second heating element 17, and the ultrasonic atomizer 16 atomizes the water source heated to the preset temperature into water vapor. Part of the water vapor is atomized into high-temperature and high-pressure water vapor by the thermo-pressing component 2 and sprayed onto the user's feet through the massage component 3, while the other part of the water vapor is dispersed upwards into the foot bath cavity and raises the temperature inside the foot bath cavity, ensuring that the feet are wrapped in water vapor at a suitable temperature for a warm compress. The water vapor sprayed through the massage component 3 also diffuses into the foot bath cavity after contacting the user's feet, which helps to maintain the temperature inside the foot bath cavity.

[0033] In actual operation, the housing 1 is equipped with a control board to uniformly control the hot pressing assembly 2, the steam generation assembly 14, and the massage assembly 3, ensuring coordinated operation of each assembly and providing comfortable foot bath, drying, and massage functions. The hot pressing assembly 2 includes a pump body 18 and a first heating element 19. The pump body 18 draws steam generated in the atomizing tank 15 and, after flowing through the first heating element 19, forms high-temperature steam that is delivered to the diversion channel 6. The pump body 18 draws steam from the atomizing tank 15 and increases the pressure of the steam to ensure that the steam jet speed meets the usage requirements, thereby enhancing the massage stimulation by increasing the impact force. The first heating element 19 reheats the steam to ensure that the steam temperature meets the usage requirements, thereby enhancing the massage stimulation by increasing the steam temperature.
