A foot bath

Abstract

The present invention relates to a foot bath. The existing foot bath has a small water vapor injection flow rate, resulting in poor massage stimulation intensity. The present invention includes a shell, which is provided with a partition plate, a water vapor generating component, a hot pressing component and a massage component. The water vapor generated by the water vapor generating component is processed by the hot pressing component and then ejected outward through the massage component to form massage stimulation. The hot pressing component includes a booster part, an exhaust part and a heating part connected by a vacuum generator. The booster part extracts water vapor and transports it to the vacuum generator. When the water vapor from the booster part flows through the vacuum generator, it extracts the airflow from the exhaust part and transports it to the heating part, so as to increase the water vapor flow rate. An exhaust part is arranged in the hot pressing component, and the outside air is extracted by the exhaust part and mixed with the water vapor from the booster part, so as to effectively increase the water vapor flow rate injected at the massage component, thereby improving the massage stimulation intensity and meeting the use requirements.

The water vapor generated by the water vapor generating component is processed by the heat pressing component and then sprayed outward through the massage component to form a massage stimulation. Since the amount of water vapor generated by the water vapor generating component is limited, and needs to be used for temperature regulation in the foot bath cavity and sprayed to form a massage stimulation, the amount of water vapor used to form the massage stimulation cannot meet the spray flow requirements, and then the intensity of the massage stimulation cannot meet the use requirements, affecting the massage comfort experience. Summary of the invention

[0003] In order to solve the shortcomings of the prior art, the present invention provides a foot bath, in which an exhaust part is arranged in the hot pressing component, and the outside air is drawn through the exhaust part and mixed with the water vapor from the boosting part, thereby effectively increasing the water vapor flow rate sprayed at the massage component, thereby enhancing the massage stimulation intensity to meet the usage requirements.

[0004] The present invention is realized in the following manner: a foot bath, comprising a shell with a foot bath cavity, a partition plate, a water vapor generating component located at the partition plate, a hot pressing component located below the partition plate, and a massage component located above the partition plate are provided at the bottom of the shell, the water vapor generated by the water vapor generating component is processed by the hot pressing component and then ejected outward through the massage component to form a massage stimulation, the hot pressing component comprises a booster, an exhaust and a heating part connected by a vacuum generator, the booster extracts water vapor and delivers it to the vacuum generator, the water vapor from the booster extracts the airflow from the exhaust when flowing through the vacuum generator and delivers it to the heating part, so as to increase the water vapor flow. An exhaust is provided in the hot pressing component, the outside air is extracted by the exhaust and mixed with the water vapor from the booster, the air extracted by the exhaust and the water vapor output by the booster are mixed and delivered to the massage component, the ejection flow of the massage component is effectively increased, and then the massage comfort is improved by increasing the intensity of the massage stimulation, and the user experience is improved. The separation plate not only serves to fix and position the water vapor generating component, the heat pressing component and the massage component, but is also used to form the bottom wall of the foot bath cavity, thereby isolating and protecting the heat pressing component below.

[0005] Preferably, the vacuum generator includes an air inlet connected to the pressurizing part, a vacuum port connected to the exhaust part, and an exhaust port connected to the heating part. The water vapor generated by the pressurizing part is transported to the exhaust port through the air inlet to form a negative pressure area at the side vacuum port, which is conducive to the transport of air from the exhaust part to the exhaust port, reduces the air flow pressure requirement generated by the fan, facilitates the air flow to be input into the vacuum generator at a lower pressure and mixed with high-pressure water vapor to increase the air volume, and prevents the water vapor in the vacuum generator from flowing back to the fan through the vacuum port, thereby protecting the fan.

[0006] Preferably, the air extraction unit includes a fan and a one-way valve, wherein the one-way valve is arranged between the fan outlet and the vacuum port to limit the backflow of water vapor in the vacuum generator to the air extraction unit. The fan extracts external air and delivers it to the vacuum port, so that the air and water vapor are mixed in the vacuum generator and delivered to the massage component. The one-way valve is used to control the air flow direction, prevent the water vapor and air in the vacuum generator from backflowing through the vacuum port, and prevent the water vapor from being depressurized when flowing through the vacuum generator.

[0007] Preferably, the inlet of the fan is connected to the external space to provide an air source for the fan. The fan inlet is exposed to the external space, which not only ensures sufficient air source, but also increases the extracted air volume by reducing wind resistance.

[0008] Preferably, the pressurizing unit includes a pump body and a control valve, and the control valve is arranged between the pump body outlet and the air inlet to limit the backflow of water vapor in the vacuum generator to the pressurizing unit. The pressurizing unit can extract water vapor generated by the water vapor generating component and transport it to the vacuum generator after pressurization, and increase the flow rate when passing through the vacuum generator by increasing the pressure of the water vapor, thereby increasing the negative pressure effect at the vacuum port, facilitating the vacuum port to extract air from the air extraction unit, and thereby increasing the injection flow at the massage component. The control valve can control and guide the flow direction of water vapor, prevent the water vapor in the vacuum generator from flowing back to the pump body, and help the water vapor maintain high pressure in the vacuum generator.

[0009] Preferably, the pressurizing unit includes an elastic airbag disposed between the air outlet of the pump body and the control valve, and the elastic airbag stores water vapor from the pump body by expanding. The elastic airbag can use its own deformation to store water vapor and increase the water vapor pressure, so as to deliver high-pressure and high-flow water vapor to the air inlet when the control valve is opened, effectively improving the massage comfort.

[0010] Preferably, the vacuum generator is T-shaped, the air inlet and the exhaust port are coaxially arranged, and the diameter of each section of the air inlet gradually decreases toward the exhaust port to increase the flow rate of the air flow in the air inlet to the exhaust port, and the high-pressure and high-flow water vapor at the air inlet can be transported to the exhaust port along a straight path, effectively reducing the loss along the way when the water vapor is transported. The air inlet is a constricted structure along the water vapor flow direction, and the negative pressure effect at the vacuum port is enhanced by increasing the water vapor flow rate.

[0011] Preferably, the exhaust port is in a flared shape extending away from the air inlet, and the exhaust port is in a flared shape along the water vapor flow direction, which is conducive to the water vapor being discharged from the vacuum generator, thereby increasing the water vapor flow rate.

[0012] Preferably, the water vapor generation component is arranged in the atomizing tank at the bottom of the foot bath cavity, and the pump body extracts the water vapor generated in the atomizing tank and transports it to the heating part through the vacuum generator. There is a water source in the atomizing tank, and the water source forms water vapor through the water vapor generation component. The pump body extracts the water source and mixes it with the air from the fan in the vacuum generator and flows through the heating part, so that the water vapor forms high-temperature water vapor that meets the pressure, flow and temperature requirements.

[0013] Preferably, the water vapor generating component includes an ultrasonic atomizer, and the water source in the atomizing tank forms water vapor through the ultrasonic atomizer. The ultrasonic atomizer can atomize the water source to form water vapor, which not only provides water vapor for the hot pressing component, but also provides temperature-adjustable water vapor for the foot bath cavity.

[0014] Preferably, the water vapor generating assembly includes a temperature rising component, which heats the water source. The temperature rising component heats the water source in the atomizing tank so that the water vapor temperature reaches the required temperature in the foot bath cavity.

[0015] Preferably, the massage component comprises a massage head arranged at the bottom of the foot bath cavity, and a nozzle is arranged on the massage head, the nozzle receives the water vapor from the hot pressing component and sprays it outward to form a massage stimulation. The nozzle receives the water vapor mixed with air and sprays it into the foot bath cavity, and the impact force of the water vapor hitting the user's feet forms a massage stimulation.

[0016] The beneficial effects of the present invention are as follows: an exhaust section is arranged in the hot pressing component, through which external air is extracted and mixed with water vapor from the pressurizing section; the air extracted by the exhaust section and the water vapor output by the pressurizing section are mixed and then transported to the massage component, thereby effectively increasing the injection flow rate of the massage component, thereby improving the massage comfort and enhancing the user experience by increasing the intensity of the massage stimulation.

An exhaust section is arranged in the hot pressing assembly 2, the air outside is extracted by the exhaust and mixed with the water vapor from the booster, the air extracted by the exhaust and the water vapor output by the booster are mixed and delivered to the massage assembly 3, effectively increasing the ejection flow of the massage assembly 3, and then improving the massage comfort and the user experience by increasing the intensity of the massage stimulation.

[0026] In actual operation, the inlet of the fan 9 is connected to the external space to provide an air source for the fan 9. The air extraction section includes a fan 9 and a one-way valve 10, and the one-way valve 10 is arranged between the outlet of the fan 9 and the vacuum port 6 to limit the water vapor in the vacuum generator 4 from flowing back to the air extraction section. The air in the external space is extracted by the fan 9 and transported to the vacuum generator 4, and the water vapor flow rate is increased by mixing with the water vapor, thereby increasing the injection impact force of the massage component 3, enhancing the massage stimulation, and improving the user experience. The one-way valve 10 can prevent the water vapor from flowing back to the fan 9, which not only protects the fan 9, but also ensures that a higher pressure is maintained in the vacuum generator 4 to meet the water vapor injection requirements.

[0027] In actual operation, the vacuum generator 4 includes an air inlet 7 connected to the pressurizing part, a vacuum port 6 connected to the exhaust part, and an exhaust port 8 connected to the heating part 5 (such as Figure 2 The vacuum generator 4 is T-shaped (as shown). Figure 3 As shown), the air inlet 7 and the exhaust port 8 are coaxially arranged with each other, and the high-pressure water vapor formed by the pressurization part flows toward the exhaust port 8 through the air inlet 7, and takes away the air at the vacuum port 6, so that a negative pressure area is formed at the vacuum port 6, ensuring that the vacuum generator 4 can use the negative pressure area to assist air input into the vacuum port 6 when the water vapor pressure at the air inlet 7 is greater than the air pressure at the vacuum port 6, so as to ensure that the water vapor can mix with the air and increase the flow rate.

[0028] In actual operation, the diameter of each section of the air inlet 7 gradually decreases toward the exhaust port 8 to increase the flow rate of the air flow in the air inlet 7 toward the exhaust port 8, and the negative pressure effect at the vacuum port 6 is increased by increasing the flow rate of water vapor between the air inlet 7 and the exhaust port 8, thereby ensuring that the air from the fan 9 can be smoothly input into the vacuum generator 4.

[0029] In actual operation, the exhaust port 8 is in a flared shape extending away from the air inlet 7 (eg Figure 4 As shown), the flared structure is beneficial for increasing the flow rate so that the water vapor in the vacuum generator 4 can be quickly transported outward, thereby forming high-pressure and high-flow water vapor at the nozzle 15, thereby enhancing the intensity of massage stimulation by increasing the impact force.

[0030] In actual operation, the pressurizing part includes a pump body 11 and a control valve 12. The control valve 12 is arranged between the outlet of the pump body 11 and the air inlet 7 to limit the backflow of water vapor in the vacuum generator 4 to the pressurizing part. The pressurizing part includes an elastic airbag 13 arranged between the air outlet of the pump body 11 and the control valve 12. The elastic airbag 13 stores water vapor from the pump body 11 by expansion. The pump body 11 continuously operates and stores the generated high-pressure water vapor in the elastic airbag 13. The control valve 12 controls the water vapor flow state by switching on and off, and then forms differentiated massage stimulation by controlling the water vapor injection state, such as forming an interval massage stimulation by injecting water vapor at intervals, or forming a continuously applied massage stimulation by continuously injecting water vapor, which should be regarded as specific embodiments of the present invention.

[0031] In actual operation, the one-way valve 10 and the control valve 12 can be opened and closed synchronously, so that the fan 9 can replenish air when the booster delivers water vapor to the vacuum generator 4, ensuring that the fan 9 and the pump body 11 work in coordination.

[0032] In actual operation, a control panel is provided in the shell 1 to uniformly control the hot pressing component 2, the water vapor generating component and the massage component 3, ensuring the coordinated operation of each component and providing comfortable foot bathing, drying and massage functions.

[0033] In actual operation, the water vapor generating component is arranged in the atomizing groove 17 at the bottom of the foot bath cavity, and the pump body 11 extracts the water vapor generated in the atomizing groove 17 and transports it to the heating part 5 through the vacuum generator 4. The water vapor generating component includes an ultrasonic atomizer 18 and a temperature rise component 19. The water source in the atomizing groove 17 forms water vapor through the ultrasonic atomizer 18, and the temperature rise component 19 heats the water source. The water source in the atomizing groove 17 is heated to a preset temperature by the temperature rise component 19, and the ultrasonic atomizer 18 atomizes the water source heated to the preset temperature to form water vapor. A part of the water vapor forms high-temperature and high-pressure water vapor through the hot pressing component 2 and is sprayed to the user's feet through the massage component 3, and the other part of the water vapor drifts upward to the foot bath cavity and increases the temperature in the foot bath cavity, ensuring that the foot is wrapped in water vapor of suitable temperature for hot compress. The water vapor sprayed by the massage component 3 will also diffuse into the foot bath cavity after contacting the user's foot, which is used to maintain the temperature in the foot bath cavity.

[0034] In actual operation, the massage component 3 includes a massage head 14 arranged at the bottom of the foot bath cavity, and the massage head 14 is provided with a nozzle 15, which receives the water vapor from the hot pressing component 2 and forms a massage stimulation by spraying outward (such as Figure 5 The upper end of the nozzle 15 forms a plurality of nozzle holes 20 (as shown in FIG. Figure 6As shown in the figure, the lower port is used to receive water vapor from the exhaust port 8, so that the water vapor can be sprayed into the foot bath cavity through the nozzle 15, and form a massage stimulation when it hits the user's feet.
