Description

Technical Field

[0001] This utility model relates to the field of health care, specifically to a water vapor jet rotating massage foot bath with good airtightness. Background Technology

[0002] Existing foot baths provide a static sauna experience by diffusing warm water vapor within a foot bath chamber and enveloping the user's feet. They also utilize pressurized jets of warm water vapor to create fluid jets that impact the feet, generating a massage stimulation. Because these foot baths rely on flowing water vapor for massage, they require excellent sealing and airtightness. Utility Model Content

[0003] The purpose of this invention is to provide a water vapor jet rotating massage foot bath device with good airtightness, which ensures the sealing and airtightness of water vapor during transportation and avoids leakage.

[0004] To achieve the above objectives, the water vapor jet rotating massage foot bath device of this utility model with good airtightness includes a massage component, which includes a water vapor dispersion plate and multiple rotating massage nozzles;

[0005] The water vapor dispersion plate is distributed with water vapor dispersion channels, and multiple installation interfaces are distributed along the water vapor dispersion channels. Each installation interface is fixed with a bushing.

[0006] The rotating massage nozzle includes a head and a tubular shaft. The head has spray holes, and the tubular shaft is rotatably and sealed to the bushing. The upper end of the tubular shaft is sealed to the head and communicates with the spray holes, while the lower end of the tubular shaft is open to the water vapor dispersion channel.

[0007] Accordingly, the rotating massage nozzle achieves its rotation through the rotation of the tubular shaft and bushing. Furthermore, the tubular shaft and bushing are sealed and rotated, and the upper end of the tubular shaft is sealed and connected to the head, thereby ensuring a seal and preventing water vapor from leaking from the connection of the tubular shaft, which could adversely affect the internal structure of the foot bath. At the same time, it ensures that all water vapor is sprayed out from the spray hole of the head to maintain appropriate pressure to achieve a stimulating massage effect.

[0008] Preferably, the bushing is fixed to the mounting interface by threads. This facilitates both assembly and sealing between the bushing and the mounting interface.

[0009] Preferably, the tubular shaft passes through the bushing and extends downwards into a lower shaft section, on which at least one rotating retaining ring is fitted. The rotating retaining ring both constrains the tubular shaft to the bushing and acts as a seal to prevent moisture leakage from the rotational gap between the tubular shaft and the bushing. In particular, since the rotating retaining ring is fitted onto the lower shaft section rather than being squeezed between the inner walls of the tubular shaft and the bushing, the resistance generated by the rotating retaining ring is smaller when the tubular shaft rotates relative to the bushing, thereby ensuring the flexibility of the tubular shaft. Furthermore, using multiple rotating retaining rings can increase the seal life.

[0010] Preferably, the tubular shaft passes through the bushing and extends above the bushing to form an upper shaft section. The upper shaft section is fitted with at least one sealing ring, which is pressed between the upper shaft section and the head. This ensures a seal between the tubular shaft and the head.

[0011] Preferably, the massage assembly includes a mounting plate, a drive gear, and a plurality of driven gears;

[0012] The mounting plate is located above the water vapor dispersion plate, and there is an installation space between it and the water vapor dispersion plate. The installation space is isolated from the water vapor dispersion channel.

[0013] Multiple driven gears are located in the installation space and are configured one by one with the rotating massage head to drive the rotating massage head to rotate;

[0014] The drive gear is located in the mounting space and is used to drive the plurality of driven gears to rotate.

[0015] This massage component uses drive gears and driven gears to rotate multiple rotating massage nozzles to massage the feet. Furthermore, the gear transmission ensures that each rotating massage nozzle moves synchronously, providing comprehensive massage stimulation and enhancing the foot bath experience. During the foot massage, water vapor from the vapor dispersion channel is delivered to and sprayed out of each nozzle, changing its spray direction as the nozzle rotates, further enhancing the foot bath experience. Moreover, because the installation space and the vapor dispersion channel are isolated from each other, and due to the aforementioned sealing mechanism, the drive gears and driven gears located in the installation space do not come into contact with water vapor, maintaining a reliable transmission relationship.

[0016] Preferably, the driven gear is driven to the upper shaft section and the head drive assembly. This allows the driven gear to rotate the tubular shaft and the head together, rather than the tubular shaft rotating relative to the head, thereby ensuring a good seal at the connection between the tubular shaft and the head and extending its seal life.

[0017] Preferably, the plurality of rotating massage nozzles are arranged symmetrically in two rows to form two parallel areas, each area being used to massage one foot, increasing comfort; the plurality of driven gears are arranged symmetrically in two rows, with driven gears in the same row meshing sequentially. Through the sequential meshing of the driven gears, adjacent rotating massage nozzles rotate in opposite directions. During a foot bath, moving the feet can provide different massage stimuli; the drive gear is located between the two rows of driven gears and meshes with one of the driven gears in each row, simplifying the transmission structure and maintaining consistent movement of the two rows of rotating massage nozzles.

[0018] Preferably, the water vapor dispersion channel includes a first dispersion channel, a second dispersion channel, and a connecting channel. The first and second dispersion channels are symmetrical, and the connecting channel is located between and connects the first and second dispersion channels. An input interface is provided in the middle of the connecting channel. Water vapor can be uniformly delivered to each rotating massage nozzle through the input interface.

[0019] Preferably, the head is equipped with protruding ball bearings, and the outer end of the spray nozzle is lower than the ball bearings. The ball bearings can apply massage to the feet as the massage head rotates, and because the ball bearings can rotate, the massage is more comfortable. Furthermore, because the outer end of the spray nozzle is lower than the ball bearings, the spray nozzle will not be blocked when the feet are placed on the rotating massage head, ensuring the massage effect of the water vapor spray. In particular, when the spray nozzle can smoothly spray water vapor, it prevents the pressure inside the head and the tubular shaft from increasing, which could lead to leakage at the connection between the tubular shaft and the bushing, and the head.

[0020] Preferably, the foot bath also includes:

[0021] Heating and atomizing components for heating atomized water;

[0022] A water vapor pressurization component is used to pressurize the water vapor generated by the heating atomization component and deliver it to the water vapor dispersion channel;

[0023] A mechanical power unit that provides power to drive gears.

[0024] Accordingly, when in operation, the heating and atomizing components, the water vapor pressurization components, and the mechanical power components are activated, which enables the rotating massage nozzle to rotate and spray water vapor, allowing users to achieve a comfortable foot bath experience.

[0025] This invention configures a massage component including a water vapor dispersion plate and multiple rotating massage nozzles. The water vapor dispersion plate has water vapor dispersion channels, and multiple mounting interfaces are distributed along these channels, each with a fixed bushing. Each rotating massage nozzle includes a head and a tubular shaft. The head has spray holes, and the tubular shaft is correspondingly and rotatably fitted with the bushings. The upper end of the tubular shaft is sealed to the head and communicates with the spray holes, while the lower end of the tubular shaft is open to the water vapor dispersion channels. Accordingly, the rotating massage nozzles rotate by the rotation of the tubular shafts and bushings. Furthermore, the sealed rotational fit between the tubular shaft and bushings, and the sealed connection of the upper end of the tubular shaft to the head, ensures a seal, preventing water vapor leakage from the connection points of the tubular shaft and avoiding adverse effects on the internal structure of the foot bath. It also ensures that all water vapor is sprayed from the spray holes of the head, maintaining appropriate pressure to achieve a stimulating massage effect.

[0026] This invention involves inserting a tubular shaft through a bushing and extending a lower shaft section below the bushing. At least one rotating retaining ring is fitted onto the lower shaft section. The rotating retaining ring both constrains the tubular shaft to the bushing and provides a seal to prevent moisture leakage from the rotational gap between the tubular shaft and the bushing. In particular, because the rotating retaining ring is fitted onto the lower shaft section rather than being squeezed between the inner walls of the tubular shaft and the bushing, the resistance generated by the rotating retaining ring is reduced when the tubular shaft rotates relative to the bushing, thereby ensuring the flexibility of the tubular shaft. Furthermore, using multiple rotating retaining rings can increase the sealing life. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0048] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this utility model are intended to cover non-exclusive inclusion, such as a method or product that includes a series of technical features, not limited to those technical features explicitly listed, but also including other technical features that may be included in the method or product but not explicitly listed.

[0049] In the description of this utility model, it should be understood that the technical features defined by terms such as "first" and "second" which have a sequential concept are only for the purpose of clearly describing the defined technical features and making the defined technical features clearly distinguishable from other technical features, and do not represent that they are named in this way in actual implementation. Therefore, they should not be construed as limitations on this utility model.

[0050] The present invention will now be described in detail with reference to specific embodiments and accompanying drawings.

[0051] Figure 1 A foot bath device is shown, comprising: a foot bath cavity, a massage component 100, a heating and atomizing component 200, a water vapor pressurization component 300, a mechanical power component 400, and a circuit control board.

[0052] The foot bath chamber is defined between the upper housing 500 and the massage component 100. The upper housing 500 has an opening 501 for the feet to enter and exit the foot bath chamber. The upper housing 500 also has an insertion port 502 for inserting a water bottle 800 to add water to the heated atomizing water tank 210. The upper housing 500 is also equipped with a control screen 503 for displaying the working status of the foot bath and controlling the foot bath.

[0053] The massage assembly 100 includes a water vapor dispersion plate 110, a mounting plate 120, multiple rotating massage nozzles 130, multiple driven gears 140, and a drive gear 150.

[0054] like Figure 2 , Figure 5 As shown, the water vapor dispersion plate 110 is a plate-shaped component with water vapor dispersion channels distributed on it. These channels disperse the incoming water vapor to distribute it evenly to each rotating massage nozzle. Multiple mounting interfaces 115 are distributed along the water vapor dispersion channels, and each mounting interface is fixed with a bushing 116. The bushing 116 is threaded to the mounting interface 115, facilitating both assembly and sealing between the bushing and the mounting interface.

[0055] The mounting plate 120 is also a plate-like component located on the upper side of the water vapor dispersion plate 110. It maintains an installation space with the water vapor dispersion plate, and the installation space is isolated from the water vapor dispersion channel to prevent water vapor in the water vapor dispersion channel from entering the installation space and causing adverse effects on the structure in the installation space, such as gears.

[0056] Multiple rotating massage nozzles 130 are rotatably distributed on the upper side of the mounting plate 120 and extend downward through tubular axes into the water vapor dispersion channels. Specifically, as shown... Figure 3 As shown, the rotary massage nozzle 130 includes a head 1301 and a tubular shaft 1306. The head 1301 has a water vapor chamber 1303 and a plurality of spray holes 1302 for spraying water vapor outward from the water vapor chamber. The tubular shaft 1306 is sealed and rotatably assembled with the bushing 116 in a corresponding manner. The upper end of the tubular shaft 1306 is sealed and connected to the head and communicates with the spray holes 1302 through the water vapor chamber 1303. The lower end of the tubular shaft 1306 is open to the water vapor dispersion channel for receiving water vapor from the water vapor dispersion channel.

[0057] like Figure 4 As shown, the head 1301 is also equipped with protruding ball bearings 1305, which are constrained within the mounting cavity 1304 of the head. The outer port of the spray nozzle 1302 is lower than the ball bearings 1305. The ball bearings can apply massage to the feet as the rotating massage head rotates, and because the ball bearings can rotate, the massage applied to the feet is more comfortable. Furthermore, because the outer port of the spray nozzle is lower than the ball bearings, the spray nozzle will not be blocked when the feet are placed on the rotating massage head, ensuring the massage effect of the water vapor spray.

[0058] Furthermore, such as Figure 3 As shown, a tubular shaft 1306 passes through a bushing 116 and extends downwards to form a lower shaft section 1307. At least one rotating retaining ring 1308 is fitted onto the lower shaft section. The rotating retaining ring both constrains the tubular shaft to the bushing and acts as a seal to prevent moisture leakage from the rotational gap between the tubular shaft and the bushing. In particular, the rotating retaining ring is fitted onto the lower shaft section rather than being pressed between the inner walls of the tubular shaft and the bushing. This results in less resistance when the tubular shaft rotates relative to the bushing, thus ensuring the flexibility of the tubular shaft. Multiple rotating retaining rings can increase the seal life. The tubular shaft 1306 also extends upwards to form an upper shaft section 1309, which is fitted with at least one sealing ring 1310. The sealing ring 1310 is pressed between the upper shaft section 1309 and the head 1301. This ensures a seal between the tubular shaft and the head.

[0059] Based on the above structure, the water vapor distributed to each rotating massage nozzle by the water vapor dispersion channel will not leak except from the spray holes of each rotating massage nozzle, thus ensuring the sealing effect and the massage effect of the spray stimulation.

[0060] Multiple driven gears 140 are located within the mounting space and are individually configured with the rotating massage head 130 to drive the rotating massage head to rotate. Specifically, the driven gears 140 are driven by the upper shaft section 1309 and the head 1301. The structure shown in the figure has a square shaft portion 1311 on both the upper shaft section and the head, and the driven gears 140 have square holes 141. The square holes 141 fit into the square shaft portions 1311 of the upper shaft section and the head to drive the entire rotating massage head to rotate, preventing the tubular shaft from rotating relative to the head.

[0061] The drive gear 150 is located in the mounting space and is used to drive multiple driven gears to rotate.

[0062] The massage assembly with the above structure delivers water vapor to each rotating massage nozzle through a water vapor dispersion channel. Driven gears and driven gears rotate multiple rotating massage nozzles to apply a contact-type mechanical massage to the feet, as well as a stimulating massage from the water vapor sprayed from the nozzles. Furthermore, the gear transmission allows each rotating massage nozzle to move synchronously, providing comprehensive massage stimulation to the feet and enhancing the foot bath experience. During the foot massage by the rotating massage nozzles, water vapor from the water vapor dispersion channel is delivered to and sprayed out of each nozzle, changing its spray direction as the nozzles rotate, further enhancing the foot bath experience.

[0063] In the illustrated structure, multiple rotating massage nozzles 130 are symmetrically distributed in two rows along the first dispersion channel 111 and the second dispersion channel 112, forming two parallel areas. Each area is used to massage one foot, increasing comfort. Correspondingly, multiple driven gears 140 are symmetrically distributed in two rows, with driven gears in the same row meshing sequentially. Thus, through the sequential meshing of the driven gears, adjacent rotating massage nozzles rotate in opposite directions, allowing for different massage stimuli to be obtained by moving the feet during a foot bath. Furthermore, a drive gear 150 is located between the two rows of driven gears and meshes with one of the driven gears in each row. This simplifies the transmission structure and maintains consistent operation of the two rows of rotating massage nozzles. The driven gears in the same row can maintain a difference in diameter, thereby achieving different rotational speeds for the different rotating massage nozzles.

[0064] In the illustrated structure, the water vapor dispersion channel includes a first dispersion channel 111, a second dispersion channel 112, and a connecting channel 113. The first dispersion channel 111 and the second dispersion channel 112 are symmetrical about each other. The connecting channel 113 is located between the first and second dispersion channels and connects them. An input interface 114 is provided in the middle of the connecting channel 113, and the input interface 114 is located on the lower surface of the water vapor dispersion plate 110. Accordingly, water vapor can be uniformly delivered to each rotating massage nozzle through the input interface.

[0065] The heating atomizing assembly 200 is used to heat and atomize water. It includes a heating atomizing water tank 210, a first heating element 220, and an ultrasonic atomizer 230. The first heating element and the ultrasonic atomizer are positioned at the bottom of the heating atomizing water tank. After water is added to the heating atomizing water tank, the first heating element and the ultrasonic atomizer are submerged in water to atomize and heat the water into water vapor. A cover 240 is provided above the heating atomizing water tank 210, forming a diffusion cavity above the heating atomizing water tank between the cover 240 and the heating atomizing water tank 210. This allows for the heating and atomization of the water stored in the heating atomizing water tank. The diffusion cavity provides space for heating and atomization, ensuring the efficiency of heating and atomization. The cover defines the diffusion cavity. The cover 240 protrudes from the foot bath cavity. The heated atomizing water tank 210 is mounted on the lower side of the partition plate 620. The partition plate 620 and the positioning plate 610 are provided with openings corresponding to the heated atomizing water tank. The openings connect the heated atomizing water tank 210 and the diffusion cavity, promoting efficient heating and atomization. The side wall of the diffusion cavity has an intake port 211 and a water vapor channel. The intake port is preferably located on the side wall of the heated atomizing water tank 210, so as not to be submerged in water. The intake port 211 is connected to the pressurization pump of the water vapor pressurization component. The first heating device 220 and the ultrasonic atomizer 230 are arranged at the bottom of the heated atomizing water tank, so that the water in the heated atomizing water tank 210 can be atomized and heated into water vapor. At any stage of operation, when the pressure of the diffusion cavity is less than the pressure of the foot bath cavity, the water vapor in the foot bath cavity flows back to the diffusion cavity through the water vapor channel. When the pressure of the foot bath cavity is less than the pressure of the diffusion cavity, the water vapor in the diffusion cavity will escape into the foot bath cavity through the water vapor channel.

[0066] like Figure 6 As shown, the water vapor pressurization assembly 300 is used to pressurize the water vapor generated by the heated atomizing water tank 200 and deliver it to the water vapor dispersion channel. The water vapor pressurization assembly 300 may include a pressurization pump 301, a delivery pipe 302, and a first check valve 303, a storage tank 304, a control valve 305, a second heating element 306, a second check valve 307, and a fan 308 disposed in the delivery pipe path. The pressurization pump 301 has an inlet pipe 309, which is connected to the suction port 203 of the heated atomizing water tank 200. One end of the delivery pipe 302 is connected to the outlet of the pressurization pump 301, and the other end is connected to the input interface of the water vapor dispersion channel. During foot bath, the pressurization pump 301 draws water vapor from the heated atomizing water tank through the inlet pipe 309 and the suction port 203, and pressurizes the water vapor. The water vapor flows through the first one-way valve 303, the control valve 305, and the second heating element 306 before entering the water vapor dispersion channel through the input interface and being distributed to each rotating massage head. The first and second one-way valves are used to prevent water vapor backflow. The control valve is used to control the opening and closing of the delivery pipe and the flow rate. The second heating element can be used to heat the flowing water vapor.

[0067] When the water vapor produced by the heating atomizing component 200 is insufficient or / and the power of the pressurizing pump is inadequate, the water vapor pressurizing component 300 cannot continuously spray a high-speed water vapor stream. While typical pressurizing pumps, such as airbag pumps, can continuously inflate, they cannot achieve high-pressure air delivery. Forcing the pressurizing pump to deliver high-pressure air would result in a severe suction sensation above the foot bath cavity and increased pump noise. Therefore, using a storage tank to accumulate and store water vapor, and then intermittently releasing it, ensures that the water vapor pressurizing component 300 can continuously spray a high-speed water vapor stream with lower operating noise. Given the function of the storage tank, it is preferably made of an elastic material, making it function like an elastic bladder.

[0068] After the foot bath, the fan can be turned on to generate airflow. When the airflow passes through the second heating device, it is heated into hot air. The hot air flows through the water vapor circulation path to achieve heating and drying.

[0069] The water vapor dispersion plate 110 is disposed on the positioning plate 610, and a partition plate 620 is also provided on the lower side of the positioning plate 610. The positioning plate and the partition plate keep the foot bath cavity in a relatively sealed space, and the water vapor is circulated between the heated atomizing water tank 210, the water vapor pressurizing component 300, the water vapor dispersion channel, the rotating massage nozzle 130, the foot bath cavity, and the diffusion cavity under the action of the water vapor pressurizing component 300.

[0070] The water vapor pressurization component 300, the mechanical power component 400 and the circuit control board are fixed to the lower side of the partition plate 620 and shielded by the lower housing 700, and are isolated from the foot bath cavity by the positioning plate 610 and the partition plate 620.

[0071] The mechanical power assembly 400 is used to provide power to the drive gear. It is preferably a combination of a motor and a worm gear transmission mechanism. The worm gear and the drive gear are driven coaxially. The transmission shaft 401 passes through the positioning disk 610 and the partition disk 620 and is connected to the worm gear and the drive gear.

[0072] The circuit control board is electrically connected to the first heating element 220, ultrasonic atomizer 230, pressurizing pump 301, first one-way valve 303, control valve 305, second heating element 306, second one-way valve 307, fan 308, motor of mechanical power component, control panel and other electrical components, and is used to control the operation of the foot bath.

[0073] The aforementioned foot bath device, when in operation, activates the first heating element 220, ultrasonic atomizer 230, water vapor pressurization component 300, and mechanical power component 400 via the control panel. This causes the rotating massage nozzle 130 to rotate, while simultaneously heating the water vapor and ejecting it from the spray holes 1302 of the rotating massage nozzle 130. Placing the feet on the corresponding rotating massage nozzle provides both mechanical contact massage and stimulating water vapor massage. Furthermore, moving the feet allows for different massage experiences on the same area of ​​the foot.
