Description

A body steam bath device Technical Field

[0001] This invention relates to the field of steam bath technology, and more particularly to a steam bath that adapts to leg length. Background Technology

[0002] A steam bath is a health care device that stimulates and massages the feet, activating the body's potential functions, adjusting imbalances in yin and yang, relieving overall tension, and achieving disease prevention and health maintenance effects. Therefore, people often use steam baths for foot baths and massages, which not only promote local blood circulation but also relieve fatigue.

[0003] Existing home-use body steam baths still have some design shortcomings. First, when the legs are inserted into the steam chamber, due to differences in leg length, it is difficult to ensure that the steam evenly covers the entire leg area, especially the lower part of the legs, where steam leakage often occurs, significantly reducing the steam bath's effectiveness. For example, Chinese patent CN202074680U discloses a far-infrared tourmaline health foot bath tub that is easy to assemble and disassemble, and Chinese patent CN213884193U discloses a steaming foot bath basin; both of these products suffer from unreasonable structural design and steam leakage problems.

[0004] Therefore, in order to solve the problems of existing technology, it is necessary to provide an efficient and comfortable steam bath solution to meet people's pursuit of a healthy lifestyle.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0082] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, features in the following embodiments can be combined with each other.

[0083] As shown in Figures 1-27, the present invention provides a body steam bath device for steam bathing a user's body. It includes a main body 100 and a steam generating component 200. The main body 100 is provided with a protective baffle 37, a leg length adaptation mechanism 300 and a foot pedal component 400 to improve the comfort of the human body during steam bathing. These will be described separately below.

[0084] The main body 100 has a fumigation chamber 1a defined by multiple walls and an inlet 1b for the legs to extend into the fumigation chamber 1a. The inlet 1b is formed on the front wall of the multiple walls. Specifically, the main body 100 includes a base 110 and a shell assembly 120 mounted on the base 110. The shell assembly 120 includes an outer shell and an inner shell 123. The inner shell 123 defines the fumigation chamber 1a. An installation space for installing the steam generating assembly 200 is formed between the rear side of the inner shell 123 and the outer shell. The rear side of the outer shell has a rear opening to facilitate the assembly of the steam generating assembly 200 onto the inner shell 123. When the steam generating assembly 200 malfunctions, it can be disassembled and maintained through the rear opening, improving ease of use. Furthermore, the assembly design of the shell assembly 120 is optimized, and the steam generating assembly 200 adopts a modular design, reducing assembly difficulty, greatly shortening assembly time, and improving assembly convenience.

[0085] Furthermore, as shown in Figure 27, due to the large volume of the inner shell 123, it is inconvenient to manufacture using molds. To solve the above problem, the inner shell 123 in this example includes a first shell 123a and a second shell 123b that are joined together in the front-to-back direction. The first shell 123a is recessed on the side away from the second shell 123b to form a first chamber, and the second shell 123b is recessed on the side away from the first shell 123a to form a second chamber. The first chamber and the second chamber together form the fumigation chamber 1a; specifically... To facilitate demolding, the first shell 123a and / or the second shell 123b have a U-shaped cross-section in the horizontal direction. By adopting the U-shaped design, the edges of the first shell 123a and / or the second shell 123b have a rounded design, which improves the demolding quality. Preferably, the volume of the cavity defined in the first shell 123a accounts for more than 50% of the volume of the fumigation cavity 1a, that is, the size of the first shell 123a is larger than the size of the second shell 123b, which makes it easier to distinguish the first shell 123a and the second shell 123b. Preferably, the first shell 123a and the second shell 123b are made of materials with different strengths; for example, the first shell 123a is weaker than the second shell 123b. In this embodiment, the first shell 123a is received within the outer shell in the front-rear direction, while the second shell 123b is at least partially exposed outside the outer shell. This allows the inner shell 123 to be protected by the outer shell, while the exposed second shell 123b can serve as the front outer wall of the steam bath. This design improves the overall aesthetics of the steam bath, and since the second shell 123b is part of the outer shell, the coverage area of ​​the outer shell can be reduced, saving manufacturing materials. Furthermore, the first shell 123a and the second shell 123b are interconnected by a positioning guide mechanism, which includes at least mating bolt holes and guide posts 354 to assist assembly and ensure structural stability.

[0086] The steam generating assembly 200 generates and delivers a steam flow into the fumigation chamber 1a, and this steam flow can flow upward from the bottom of the fumigation chamber 1a to provide dry soaking and fumigation for the user's lower limbs. The steam generating assembly 200 includes a water tank 220, a steam generator 210, an electrical control device 230, and a mounting base 240. The water tank 220, steam generator 210, and electrical control device 230 are all fixedly connected to the mounting base 240. Preferably, the electrical control device 230 can be a PCB board containing control circuitry or an IC chip controller, etc., to intelligently control the operation of the steam generator 210 and ensure the stability of steam delivery. The mounting base 240 is fixed to the rear opening of the outer shell. The mounting base 240 has a mounting groove on the side facing the rear opening so that the steam generator 210, the electrical control device 230 and the water tank 220 can be assembled into the mounting groove from the rear opening. The mounting groove includes a first empty groove and a second empty groove arranged at intervals, so that the steam generator 210 can be assembled into the first empty groove and the water tank 220 can be assembled into the second empty groove through the rear opening of the shell assembly 120, thereby improving the ease of assembly. In use, the water in the water tank 220 is pumped to the steam generator 210, and then the steam generator 210 generates high-temperature steam that is delivered to the fumigation chamber 1a for fumigation of the user. The shell assembly 120 further includes a rear shell 124 for closing the rear opening. The rear shell 124 is at least partially movably connected to the mounting base 240 to add water to the water tank 220 via the rear opening. This water addition method can be to directly add water to the water tank 220, or to remove the water tank 220 from the second empty slot, add water, and then reinstall it into the second empty slot. Preferably, the rear shell 124 includes an upper rear shell 124 that mates with the first empty slot and a lower rear shell 124 that mates with the second empty slot. The lower rear shell 124 can be connected to the mounting base 240 by a hinge to realize the opening and closing of the lower rear shell 124, or it can be connected by a removable method such as a slot 462c to facilitate the disassembly and assembly of the lower rear shell 124 for water replenishment operations into the water tank 220.

[0087] It also includes a scalding partition 800, a circulating fan 250, and a steam outlet pipe installed inside the fumigation chamber 1a. Because the inner shell 123 adopts a front-to-back assembly design, the installation of components such as the scalding partition 800, the circulating fan 250, and the steam outlet pipe is greatly facilitated. Specifically, as shown in Figure 3, the steam outlet pipe can cooperate with the steam generating assembly 200 to deliver high-temperature steam into the fumigation chamber 1a. To prevent the high-temperature steam from directly spraying onto the user's lower limbs and easily causing burns, the scalding partition 800 provides a barrier. The scalding partition 800 is vertically arranged on the rear side of the fumigation chamber 1a, and forms a temperature-regulating chamber with the rear wall of the fumigation chamber 1a. Gaps are left at the bottom and sides of the scalding partition 800 so that the steam flow inside the fumigation chamber 1a can flow out from the bottom and sides respectively, thus protecting the user. The legs enhance the fumigation effect; at the same time, the circulating fan 250 can draw the high-temperature steam cooled at the top of the fumigation chamber 1a into the temperature-regulating chamber, and mix it with the high-temperature steam delivered from the steam outlet pipe in the temperature-regulating chamber to ensure that the temperature in the fumigation chamber 1a is constant, thereby improving the fumigation effect of the steam bath; in order to facilitate the assembly of the anti-scalding partition 800, the circulating fan 250 and the steam outlet pipe, before assembling the first shell 123a to the second shell 123b, the anti-scalding partition 800, the circulating fan 250 and the steam outlet pipe are first assembled to the rear wall of the first shell 123a, thereby improving the ease of assembly of the steam bath.

[0088] As shown in Figures 1-9, the leg length adaptation mechanism 300 is disposed on the front wall and includes a steam baffle 330 and a force application mechanism. The steam baffle 330 is movably attached to the inlet 1b, and the size of the inlet 1b can be changed to accommodate users with different leg lengths. During use, the force application mechanism applies force to the steam baffle 330 in a direction that keeps the steam baffle 330 in contact with the lower side of the user's leg. This prevents steam from leaking from the lower side of the leg during steam bathing, ensuring the fumigation temperature in the fumigation chamber 1a and improving the fumigation effect.

[0089] Preferably, the insertion port 1b further includes an insertion port 1b formed on the top wall among the plurality of walls. The insertion ports 1b between the top wall and the front wall are interconnected to increase the opening area of ​​the insertion port 1b, making it convenient for the user to insert their legs into the fumigation chamber 1a. The main body 100 is pivotally connected to a cover plate 57 for closing the top insertion port 1b. In the steam bath state, the cover plate 57 can cover the user's knee joint, so that the user's feet, calves and knee joints are all received in the fumigation chamber 1a, ensuring the user's fumigation effect.

[0090] Furthermore, a rib 331 is formed at the upper center of the steam baffle 330 to separate the user's legs; the two sides of the rib 331 and the side wall of the main body 100 define a placement portion 332 to guide the user's legs to rest on the steam baffle 330, and the rib 331 is located in the gap between the user's legs in the steam bath state to prevent steam leakage; the steam baffle 330 extends along the width direction of the side opening 1b and forms arc-shaped portions on both sides, which fit against the inner wall of the side opening 1b.

[0091] The steam baffle 330 includes a front plate 33a and a rear plate 33b arranged front to back, with a cavity between the front plate 33a and the rear plate 33b to accommodate the guide post 354 and the force-applying spring 34, thus improving the aesthetics of the steam baffle 330. The force-applying mechanism can also employ a design of mutually cooperating blocks and slots 462c, or a ratchet rack design, to allow the steam baffle 330 to be operably adjusted up and down along the height direction. Preferably, the force-applying mechanism is configured as a force-applying spring 34, which is disposed between the steam baffle 330 and the front wall, as will be described in detail below.

[0092] As shown in Figures 7a, 7b, and 7c, a movable guide mechanism 350 is further provided between the steam baffle 330 and the main body 100 to guide the steam baffle 330 to move up and down, thereby improving the stability of the movement of the steam baffle 330. In some embodiments, the movable guide mechanism 350 includes a slidingly fitted guide groove 356 and a guide block 355, one of which is provided on the steam baffle 330 and the other is provided on the front wall. In this embodiment, the guide block 355 is formed on the front wall, the guide groove 356 is formed on the steam baffle 330, and the force spring 34 is provided between the guide block 355 and the steam baffle 330 to guide the steam baffle 330 to move up and down.

[0093] As shown in Figures 8a, 8b, and 8c, to further improve the stability of the movement of the steam baffle 330, the movable guide mechanism 350 includes a slidingly fitted guide groove 353 and a guide post 354, one of which is provided on the steam baffle 330 and the other is provided on the front wall. In this embodiment, the guide groove 353 is formed on a protrusion 352 extending from the front wall, and the guide post 354 is fixed to the steam baffle 330 and extends in the vertical direction. Furthermore, the steam baffle 330 has a slot 351 extending in the vertical direction, through which the protrusion 352 passes and slides with the guide post 354, resulting in a good guiding effect. The force-applying spring 34 is sleeved on the guide post 354, and the first end of the force-applying spring 34 abuts against the protrusion 352, and the second end abuts against the upper end of the guide post 354, so that the force-applying spring 34 provides elastic force, so that the steam baffle 330 moves stably up and down under the cooperation of the guide groove 353 and the guide post 354.

[0094] In this embodiment, a guide side plate 320 is fixedly connected to the front wall, and the movable guide mechanism 350 is disposed between the guide side plate 320 and the steam baffle 330. Specifically, the steam baffle 330 has three slots 351 spaced apart along its width, located on the left, right, and middle sides respectively; correspondingly, the guide side plate 320 has three protrusions 352 that can pass through the slots 351; the lower end of the guide post 354 passes through the guide groove 353 formed on the protrusion 352 and extends downward into the positioning hole on the steam baffle 330, and its upper end is fixed to the steam baffle 330 by bolts, thereby fixing the steam baffle 330 to the guide side plate 320, so that the steam baffle 330 slides up and down under the cooperation of the guide groove 353 and the guide post 354.

[0095] Furthermore, to limit the vertical movement of the steam baffle 330, a displacement limiting structure 360 ​​is provided between the guide side plate 320 and the steam baffle 330. Specifically, the displacement limiting mechanism includes a pair of cooperating blocking members, one of which is formed on the steam baffle 330 and the other on the guide side plate 320. Preferably, one of the blocking members is the top outer edge 361 formed on the top of the guide side plate 320, and the other is a limiting rib 331 formed on the rear wall of the steam baffle 330. When the steam baffle 330 moves upward to its limit position, that is, when it is at its highest upward position, the limiting rib 331 abuts against the top outer edge 361, thereby limiting the steam baffle 330 from moving further upward and preventing the steam baffle 330 from detaching from the guide side plate 320. Of course, in other embodiments, the displacement limiting structure 360 ​​can also be in other ways, such as a groove, a hook or other structure with limiting function, which will not be described in detail here.

[0096] Furthermore, as a preferred embodiment, the main body 100 is also provided with a guide seat 310, which defines a limiting cavity between the guide seat 310 and the front wall to guide the movement of the steam baffle 330, thereby improving the stability of the steam baffle 330's vertical movement. Specifically, the guide seat 310 has a rectangular block extending along the width direction of the main body 100; the rectangular block abuts against the two end sidewalls of the movable baffle and guides the steam baffle 330 to move vertically.

[0097] To prevent scalding of the user's inner thighs, especially the inner knee joint, by the steam in the fumigation chamber 1a during the steam bath, as shown in Figures 3-8c, a protective baffle 37 is disposed below the inlet 1b in this embodiment. This protective baffle 37 is configured to block the upward flow of the steam to the inner knee joint, thus preventing scalding. Furthermore, the fumigation chamber 1a includes a front wall, and the inlet 1b includes an opening formed in the front wall. The protective baffle 37 is disposed below the opening to precisely block the steam flow path to the inlet 1b, thereby preventing the hot steam from reaching the user's knee joint, protecting the user, and improving the fumigation effect. It should be noted that the steam temperature in the steam bath in this embodiment is configured as 40℃-65℃, preferably 45℃-55℃. The specific temperature varies from person to person. For example, some people have a low tolerance for hot temperatures and will feel uncomfortable if the temperature is higher than 50℃, while others will only feel uncomfortable if the temperature exceeds 55℃. The skin on the inner thigh, especially the skin on the inner side of the knee joint, may have a lower tolerance for hot temperatures. Therefore, a protective baffle 37 is set to block the steam and prevent the user from being scalded.

[0098] Furthermore, the protective baffle 37 is detachably connected to the front wall, which facilitates the disassembly and cleaning of the protective baffle 37 and improves the ease of use. Preferably, the protective baffle 37 is defined with a snap-fit ​​groove, and the front wall is defined with a snap-fit ​​protrusion 462b that engages with the snap-fit ​​groove. By adopting a snap-fit ​​method, disassembly and assembly are simple and convenient.

[0099] As a preferred embodiment, in this embodiment, the protective baffle 37 is configured to be movable up and down on the front wall to accommodate users with different leg lengths, improve the steam blocking effect, and thus better protect the user from being burned; preferably, the protective baffle 37 is detachably attached to the leg length adaptation mechanism 300, so as to move with the up and down movement of the leg length adaptation mechanism 300, so as to better block the steam flowing to the opening and prevent burns to the inner side of the user's knee joint.

[0100] As shown in Figures 2 to 6, the protective baffle 37 includes a downward-facing cover made of heat-insulating material, which improves the heat insulation effect of the protective baffle 37. Preferably, the cover includes an arc-shaped top surface that gradually curves downward away from the front wall, thereby better blocking the flow of steam. Moreover, the cover with the above structure can also support and limit the limbs inserted into the steam bath chamber, preventing the user's legs from approaching the front wall, allowing the steam to provide all-round steam bathing to the circumference of the legs, improving the steam bathing effect. Further, at least one protective baffle 37 is provided, with one protective baffle 37 extending along the left and right direction of the main body 100; in this embodiment, two protective baffles 37 are provided, spaced apart to accommodate the user's legs.

[0101] Foot pedal assembly

[0102] In addition, to further prevent the user's feet from being burned, a foot pedal assembly 400 suitable for supporting the feet is detachably attached to the bottom wall 521 of the main body 100, and a steam channel for the flow of fumigation steam is formed between the foot pedal assembly 400 and the bottom wall 521; wherein, the foot pedal assembly 400 includes a heat insulation plate 44 and a footrest 410 for resting the feet, the heat insulation plate 44 is disposed below the footrest 410 to prevent the heat generated by the fumigation steam from heating the footrest 410, so as to prevent the footrest 410 from being too hot and causing discomfort to the user's feet.

[0103] As shown in Figures 2 and 8, the footrest 410 and the heat insulation plate 44 are spaced apart to form a heat insulation cavity 44a between them. The heat insulation plate 44 has through holes 44b to allow some of the steam to flow into the heat insulation cavity 44a to heat the footrest 410, but at the same time, it will not cause the surface temperature of the footrest 410 to be heated too high and burn the user's feet, so that the user's feet can be more comfortable when placed on the footrest 410.

[0104] A gap exists between the footrest 410 and the inner wall of the fumigation chamber 1a, allowing steam from the steam channel to flow into the fumigation chamber 1a, gradually flowing upwards to fill it and fumigate the user's legs. Furthermore, a steam outlet 41b exists between the footrest 410 and the inner wall of the fumigation chamber 1a, allowing fumigation steam from the steam channel to flow into the fumigation chamber 1a, gradually flowing upwards to fill it and fumigate the user's legs. In this embodiment, the footrest 410 has multiple downwardly extending sidewalls on its four sides, with the steam outlet 41b formed on the left and right sidewalls. Gaps exist between these left and right sidewalls and the inner wall of the fumigation chamber 1a to ensure the fumigation steam can flow out.

[0105] Specifically, the rear wall of one of the multiple sidewall portions of the footrest 410 forms a steam inlet, and the left and right sidewalls of the multiple sidewall portions form steam outlets 41b. A steam passage is defined between the steam inlet and the steam outlet 41b. The steam inlet can be located on the left or right side of the rear wall, in the middle of the rear wall, or anywhere on the rear wall, as long as steam can enter the steam passage. In this embodiment, the steam inlet is located in the middle of the rear wall. Steam outlets 41b are formed on the left and right sidewalls of the plurality of sidewall portions. These outlets can be on the left or right sidewalls, or both sidewalls may have steam outlets 41b. In this embodiment, both sidewalls of the footrest 410 have steam outlets 41b. The steam outlets 41b are provided with a mesh structure, or they can be formed by multiple through holes 44b arranged in an array, or by a series of spaced-apart grilles. However, the invention is not limited to these designs. This design allows the steam in the steam channel to be evenly dispersed as it passes through the steam outlets 41b, thus flowing evenly into the fumigation chamber 1a and improving the steaming effect. Preferably, to reduce the impact of the steam outlets 41b on the strength of the sidewalls, a reinforcing portion is provided at the edge of any one of the steam outlets 41b, thereby ensuring the supporting strength of the sidewalls.

[0106] As shown in Figures 9-16, a steam channel is further defined between the steam inlet and the steam outlet 41b. The steam inlet is located in the middle of the rear wall, and the steam outlets 41b are formed on the left and right side walls respectively. During steam bathing or disinfection, steam enters the steam channel through the steam inlet, and then is evenly distributed in the steam channel to heat the foot pedal assembly 400. Disinfection is achieved by heating the foot pedal assembly 400, or the foot pedal assembly 400 is heated to indirectly heat the feet, thus improving the steam bathing effect on the feet. The steam outlets 41b are located on the left and right side walls so that the steam flows out from the left and right sides of the foot pedal assembly 400, avoiding direct flow to the feet and thus avoiding burns. The steam also diffuses more evenly from the sides, thus better steaming the user's lower limbs.

[0107] Furthermore, the steam inlet is configured as a "gate"-shaped inlet, which cooperates with two positioning ribs spaced apart on the left and right to form a positioning and guiding structure. This guides the footrest device to be installed in the fumigation chamber 1a and provides stable support for the footrest device. A steam channel is also formed between the two positioning ribs, guiding steam from the center into the interior of the footrest plate 410, and then dispersing it from the center to both sides, ensuring more uniform heating of the footrest device and improving the steaming effect during steam bathing. The positioning ribs have a square cross-section, which not only ensures the strength of the positioning ribs but also allows them to provide support for the footrest plate 410.

[0108] The upper surface of the footrest 410 is designed with an ergonomic tilt angle for comfortable foot placement. Multiple massage units 420 are provided on the footrest 410, and each massage unit 420 can independently move up and down freely in response to pressure applied to the soles of the feet, thus providing precise foot massage. Preferably, the multiple massage units 420 are distributed on the footrest 410 according to positions roughly corresponding to acupoints on the soles of the feet, achieving the dual effects of precise foot massage and steam heating. This steam bath not only enhances the user's health care experience but also meets the modern family's pursuit of a healthy, comfortable, and convenient lifestyle.

[0109] As shown in Figures 12-14, the multiple massage units 420 are independently arranged, offering high flexibility and the ability to provide massage to different acupoints on the foot. Furthermore, each massage unit 420 includes a massage head 421 and a return spring 422. The return spring 422 is configured to apply force to the massage head 421 in the direction that causes it to abut against the sole of the foot, allowing each massage head 421 to move freely under the influence of the foot, thus providing better massage force. The footrest 410 has multiple receiving grooves 41c suitable for receiving the massage heads 421. A limiting guide structure is provided between the massage head 421 and the receiving groove 41c to guide the massage head 421 to move along its axial direction. The limiting guide structure includes a protrusion formed on the bottom of the massage head 421 and a groove formed on the sidewall of the receiving groove 41c. The protrusion extends radially along the massage head 421 to embed into the groove, ensuring the stability of the massage head 421's movement.

[0110] Furthermore, a steam channel for the circulation of fumigation steam is formed between the footrest 410 and the bottom wall 521 of the main body 100. The massage head 421 has a cavity communicating with the steam channel, thus allowing steam to accumulate in the cavity within the massage head 421 to heat the massage head 421, achieving the dual effects of precise foot massage and steam heating. Preferably, the massage head 421 is made of a rigid material, such as rigid rubber or metal, to ensure its rigidity, thereby better stimulating acupoints on the feet and ensuring the massage effect.

[0111] The top wall of the footrest 410 is symmetrically provided with a pair of foot-shaped grooves 41a. The shape of these grooves 41a is roughly the same as the outline of the left and right feet to guide the user's feet. Multiple massage units 420 are respectively disposed in the pair of foot-shaped grooves 41a to massage the feet individually. Multiple supporting ribs are formed on the foot-shaped grooves 41a to reduce the direct contact area between the soles of the feet and the top wall of the footrest 410, thereby providing anti-scalding protection. Multiple massage heads 421 are disposed on the top wall of the footrest 410, which also creates a gap between the user's feet and the footrest 410, allowing steam to enter and steam the soles of the feet, achieving the dual effects of precise foot massage and steam heating. Multiple fixed massage protrusions 43 are distributed on the outer side of the top of the footrest 410. These fixed massage protrusions 43 are distributed on one side of the periphery of the two foot-shaped grooves 41a, and work in conjunction with the massage units 420, one moving and one stationary, to further enhance the massage effect.

[0112] Furthermore, the footrest 410 is provided with a heat insulation plate 44, which not only provides heat insulation protection but also enhances the stability of the footrest 410. The heat insulation plate 44 is spaced apart from the footrest 410 to form a heat insulation cavity 44a between them, preventing the high temperature of the steam in the steam channel from becoming too high and causing the top wall of the footrest 410 to become too hot and burn the feet, thus further improving the comfort of the user's foot steam bath. Furthermore, the heat insulation plate 44 has through holes 44b to allow some steam to flow into the heat insulation cavity 44a to heat the footrest 410, but at the same time, it will not cause the surface temperature of the footrest 410 to become too high and burn the user's feet, making it more comfortable for the user's feet to be placed on the footrest 410. In addition, the through holes 44b are connected to the inner cavity of the massage head 421 so that steam can enter the interior of the massage head 421, thereby heating the massage head 421 and improving the massage effect. Preferably, the aperture of the through hole 44b is set to allow steam to flow in but not to allow excessive or rapid flow. In this embodiment, the aperture of the through hole 44b can be 4-8mm, but other aperture sizes are also possible, such as greater than 8mm or less than 4mm. The specific size can be reasonably adjusted according to the size of the foot pedal assembly 400 and the heat collection cavity. Furthermore, multiple through holes 44b are provided and distributed on the heat insulation plate 44, so that steam can enter from multiple positions to ensure the uniformity of internal temperature. Preferably, the through hole 44b can be positioned to cooperate with the massage unit 420, that is, the through hole 44b can be located directly below the massage head 421. The massage head 421 adopts a hollow structure, which allows steam to quickly enter the interior of the massage head 421 and heat the massage head 421, thereby making the massage head 421 more effective when stimulating acupoints. Preferably, the massage head 421 is made of a flexible material, such as silicone, and the top of the massage head 421 is formed into an arc head, which will not hurt the feet while stimulating acupoints on the soles of the feet, thus improving the steam bath effect.

[0113] Furthermore, to prevent the foot pedal assembly 400 from shaking within the fumigation chamber 1a, a positioning mechanism 46 is provided between the bottom wall 521 of the main body 100 and the footrest 410. This positioning mechanism 46 includes a first limiting member 461 and a second limiting member 462 respectively located on the front and rear sides of the footrest 410. The first limiting member 461 and the second limiting member 462 simultaneously limit the front and rear sides of the foot pedal assembly 400, ensuring the stability of the foot pedal assembly 400. At least one of the first limiting member 461 and the second limiting member 462 is configured as a snap-fit ​​unit; for example, both the first limiting member 461 and the second limiting member 462 may be snap-fit ​​units, or the first limiting member 461 located on the rear side may be configured as a snap-fit ​​unit; or the second limiting member 462 located on the front side may be configured as a snap-fit ​​unit. However, the invention is not limited to these configurations. In this embodiment, the first limiting member 461 is described as an abutment protrusion 461a, and the second limiting member 462 is described as a snap-fit ​​unit.

[0114] As shown in Figures 9-11, the first limiting member 461 is configured as a rearwardly extending abutting protrusion 461a, which can be disposed in the middle of the rear side of the foot pedal assembly 400 or on any one side. Of course, there can also be two, three or four abutting protrusions 461a. In the embodiment, there are two abutting protrusions 461a, which are respectively disposed at the left and right ends of the rear side of the foot pedal assembly 400. The bottom wall 521 of the main body 100 is correspondingly formed with a limiting groove 461b42 for the abutting protrusion 461a to be inserted, thereby limiting and fixing the rear side of the foot pedal assembly 400.

[0115] The second limiting member 462 is configured as a snap-fit ​​unit, which is located at the middle of the front side of the foot pedal assembly 400. The footrest plate 410 and the heat insulation plate 4434 together define a receiving seat for accommodating the snap-fit ​​unit. The snap-fit ​​unit includes a snap-fit ​​body and a spring. The spring is installed between the snap-fit ​​body and the receiving seat. The snap-fit ​​body has a pressing protrusion 462a and a snap-fit ​​protrusion 462b that are spaced vertically and arranged in parallel. The snap-fit ​​protrusion 462b can be embedded in the slot 462c on the front side of the bottom wall 521 of the main body 100. The pressing protrusion 462a is suitable for the user's finger pressing operation to push the snap-fit ​​body to move parallel to the rear in the receiving seat, so that the snap-fit ​​protrusion 462b is away from the slot 462c, so that the foot pedal assembly 400 can be removed from the fumigation chamber 1a for easy disassembly and assembly.

[0116] Furthermore, as shown in Figures 9-16, the foot pedal assembly 400 is detachably attached to the main body 100, facilitating its removal from the fumigation chamber 1a for cleaning and maintaining its cleanliness. Further, a steam channel is formed between the foot pedal assembly 400 and the bottom wall 521 of the main body 100. When steam enters the steam channel, it spreads evenly, ensuring that the steam uniformly and comprehensively covers the foot pedal assembly 400, achieving comprehensive high-temperature disinfection and enhancing the user's health experience. Preferably, the steam channel design also allows the steam generated by the steam generator 210 to reach the foot pedal assembly 400 via the shortest path. To reduce heat loss during the flow of high-temperature steam and ensure its temperature, the high-temperature steam effectively disinfects the foot pedal assembly 400. Optionally, the steam temperature can reach above 50°C, and further, it can reach 65°C. During disinfection, the foot pedal assembly 400 is continuously disinfected by high-temperature steam, preferably for about 30 minutes, which can effectively kill about 80% of viruses and ensure the hygiene of the foot pedal assembly 400. Furthermore, if necessary, the steam temperature can reach about 100-120°C to ensure the high-temperature disinfection effect of the foot pedal assembly 400. In addition to using high-temperature steam to sterilize the footrest 410, a silver ion antibacterial coating is also provided on the footrest 410, further improving the sterilization effect inside the fumigation chamber 1a and ensuring the cleanliness and hygiene of the steam bath.

[0117] As shown in Figure 16, the main body 100 also includes a detection unit 45 for detecting the pedal assembly 400. The detection unit 45 is configured to issue a warning signal when the pedal assembly 400 is not installed in a designated position. This design allows for detection of whether the pedal assembly 400 is properly installed, ensuring safety during use. A sensing protrusion is located at the bottom front end of the pedal assembly 400. During installation, this protrusion contacts the sensing part on the detection unit 45, thereby detecting the pedal assembly 400. Optionally, the detection unit 45 can be an existing product, such as a pressure detection unit 45 or a gravity detection unit 45; the present invention is not limited to these.

[0118] Cover plate assembly

[0119] As shown in Figures 1-23, the system also includes a cover assembly 500 that can cover the top of the fumigation chamber 1a. The cover assembly 500 includes a control device 56 and a receiving space 54 for receiving the control device 56. The receiving space 54 is defined by at least one side wall and at least one bottom wall 521. A heat insulation cavity 44a is formed below the bottom wall 521. The heat insulation cavity 44a is defined by the bottom wall 521 and at least one inner lining plate 53. The heat insulation cavity 44a is configured to reduce the heat transferred from high-temperature steam to the control device 56, thereby providing heat insulation protection for the control device 56 and preventing high-temperature steam from entering the control device 56, thus ensuring the effectiveness of the control device 56.

[0120] The outer shell and the rear wall of the inner shell 123 define a device cavity for housing the steam generating assembly 200. The steam generating assembly 200 is configured to supply steam into the fumigation chamber 1a for fumigating the user's body. Both the device cavity and the fumigation chamber 1a have openings at the top, and the cover assembly 500 is attached to the top of both the device cavity and the fumigation chamber 1a. In this embodiment, the water tank 220 uses a pump to deliver water to the steam generating assembly 200, thereby generating high-temperature steam that is supplied to the fumigation chamber 1a for fumigation. It should also be noted that the steam temperature generated by the steam generating assembly 200 is approximately 45℃-65℃, preferably approximately 50℃-55℃. The steam generating assembly 200 can be a commercially available steam generator 210, which is convenient to use.

[0121] Further, as shown in Figures 18-22, the control device 56 is electrically connected to the steam generating assembly 200 via a wire to control the start and stop of the steam generating assembly 200. The control device 56 has a positioning protrusion 56b extending into the heat insulation cavity 44a. A wire-passing hole is formed in the positioning protrusion 56b for the wire to pass through, and the inner lining plate 53 has a wire-passing groove 533 for the wire to pass through. The wire passes through the wire-passing hole and the wire-passing groove 533 in sequence and is electrically connected to the control device 56 and the steam generating assembly 200 respectively. The wire-passing groove 533 is offset from the fumigation cavity 1a in the horizontal direction. Preferably, it is located above the equipment cavity, so that the wire can directly pass into the equipment cavity and be electrically connected to the steam generating assembly 200, thereby preventing the high-temperature steam in the fumigation cavity 1a from entering the control device 56 to a certain extent. Furthermore, a through hole 44b is formed on the bottom wall 521 for the positioning protrusion 56b to pass through. The through hole 44b can be configured as an oblong hole to better allow the positioning protrusion 56b to pass through, reducing the impact of errors generated during product processing and improving the installation efficiency between the control device 56 and the bottom wall 521. It should be noted that the control device 56 can be a PLC controller with a touch screen, etc.

[0122] To ensure the heat insulation and waterproof protection of the control device 56, the cover assembly 500 further includes a mounting base and a cover 57 rotatably connected to the mounting base. The cover 57 is used to open or close the top opening of the fumigation chamber 1a to allow the user's legs to enter. As shown in Figures 18-22, the receiving space 54 is formed on the mounting base. Specifically, the mounting base includes an upper cover 51, an upper body 52, and an inner liner 53 arranged sequentially from top to bottom. The upper body 52 has a bottom wall 521 and multiple side walls, which define the receiving space 54. The upper cover 51 is attached to the receiving space 54 and has a positioning cavity 51a for positioning the control device 56 to fix the control device 56. The inner liner 53 has a downwardly recessed cavity with its top open and connected to the upper body 52. The bottom walls 521 are sealed together to define the heat insulation cavity 44a, which reduces the heat transferred from high-temperature steam to the control device 56, thereby protecting the control device 56 within the receiving space 54. Furthermore, the control device 56 is disposed within the receiving space 54 and offset from the fumigation cavity 1a, thus reducing its vertical overlap with the fumigation cavity 1a, thereby reducing the amount of high-temperature steam in contact with the heat insulation cavity 44a, and thus reducing the heat transferred to the control device 56.

[0123] Further, as shown in Figure 17, the inner lining plate 53 has an arc-shaped bottom wall portion 531. The distance between the arc-shaped bottom wall portion 531 and the bottom wall 521 gradually decreases from the side away from the fumigation chamber 1a towards the side closer to the fumigation chamber 1a. This design allows one end of the arc-shaped bottom wall 521 to gradually transition to a horizontal state, thus sealing it with the upper seat 52. It also makes the height of the heat insulation cavity 44a on one side of the equipment cavity greater than the height of the heat insulation cavity 44a on the side of the fumigation chamber 1a. This design increases the heat insulation distance between the control device 56 located at the top of the equipment cavity and the steam generating assembly 200, reducing the heat transferred from the steam generating assembly 200 to the control device 56. Meanwhile, the heat insulation distance between the control device 56 located at the top of the equipment cavity and the steam generating assembly 200 is increased, reducing the heat transferred from the steam generating assembly 200 to the control device 56. The bottom of the inner lining plate 53 in the top area is horizontal and will not affect the height inside the fumigation chamber 1a; and, as shown in Figure 2, there is a heat dissipation space between the steam generating assembly 200 and the inner lining plate 53, which can improve the heat dissipation effect of the steam generating assembly 200, thereby ensuring the normal temperature of the control device 56 when it is working.

[0124] It should be noted that a sealing structure is provided between any two adjacent parts of the upper cover 51, the upper body 52, and the inner liner 53. The sealing structure includes a sealing groove and a sealing protrusion that cooperate and seal with each other. This design not only allows the two parts to be installed in alignment, but also ensures the sealing performance between them. Furthermore, in order to improve the sealing performance between any two parts, a sealing strip is also provided to improve the overall sealing performance of the mounting base.

[0125] In a preferred embodiment, the control device 56 has a protrusion 56a extending into the fumigation chamber 1a. A lighting device and / or a disinfection device are disposed within the protrusion 56a. The bottom wall 521 has a first through groove 522 through which the protrusion 56a passes. The inner lining plate 53 has a second through groove 532 through which the protrusion 56a passes. A vertically extending wall portion exists between the first through groove 522 and the second through groove 532 to position the protrusion 56a, thereby ensuring the installation accuracy of the control device 56 and the mounting base. Preferably, the wall portion includes a first wall portion extending downward from the edge of the first through groove 522 and a second wall portion extending upward from the edge of the second through groove 532. The first and second wall portions are abutting each other to surround and position the protrusion 56a. It should also be noted that the lighting device can be configured as an ambient light to enhance the aesthetics of the device; the disinfection device can be configured as an ultraviolet germicidal lamp to sterilize and disinfect the inside of the fumigation chamber 1a, ensuring the hygiene of the device; preferably, the control device 56 also has an upwardly extending protrusion 56a, which can be equipped with an ambient light that can emit a corresponding ambient light from the outside to enhance the aesthetics of the device.

[0126] The mounting base also has a pivot seat for connecting the cover plate 57. The cover plate 57 has a pivot shaft that cooperates with the pivot seat, so that the cover plate 57 can be flipped, making it convenient for the user to open the cover plate 57 and insert it into the fumigation chamber 1a for fumigation when in use, without having to remove the cover plate 57 separately, making it more convenient to use.

[0127] In this embodiment, the body steam bath is used to steam the user's feet and legs. During use, the user can flip open the cover 57, then insert their legs into the steam chamber 1a through the top opening. The user can then control the steam generating component 200 via the control device 56 to continuously supply high-temperature steam into the steam chamber 1a, thereby steaming the legs. The operation is simple and convenient. Of course, the body steam bath in this embodiment can also be used to steam the entire body; the invention is not limited to this.

[0128] In this embodiment, as shown in FIG23, a pair of airflow baffles 58 are spaced apart along the left and right sides of the cover plate 57, so that the volume of the fumigation chamber 1a can be changed by flipping the cover plate 57. The airflow baffles 58 are configured to remain closed to the wall of the fumigation chamber 1a within a predetermined flipping range of the cover plate 57, preventing steam from escaping from the left and right sides of the cover plate 57, thus ensuring the stability and heat retention of the steam inside the fumigation chamber 1a. The depth of the fumigation chamber 1a is configured to accommodate the user's feet, lower legs, and knee joint. The top and front walls of the fumigation chamber 1a have openings, allowing the user's legs to extend from the front wall of the fumigation chamber 1a. This ensures that the cover plate 57 remains closed during fumigation, guaranteeing the fumigation effect.

[0129] Specifically, when the cover 57 is flipped open within a specified range, the airflow baffle 58 forms a barrier between the cover 57 and the openings on the left and right sides of the housing. By changing the flipping angle of the cover 57, the size of the fumigation chamber 1a can be changed to accommodate users of different lengths. In this embodiment, the specified flipping range is 0-30 degrees, and the airflow baffle 58 is positioned close to the wall of the fumigation chamber 1a. This effectively prevents steam from escaping from the left and right sides of the cover 57 during flipping. It should be noted that "positioned close to the wall of the fumigation chamber 1a" means minimizing the gap between them, such as 2mm, 1mm, 0.5mm, or 0.3mm, and ideally, fitting snugly against the wall of the fumigation chamber 1a.

[0130] It should also be noted that the airflow baffle 58 includes an inclined lower edge, which remains closed with the cavity wall within the specified flipping range. As shown in Figure 23, the front wall of the fumigation cavity 1a has an opening for limbs to enter. The lower edge is formed by gradually sloping downwards from a position on the cover away from the opening towards the opening; the angle between the downward sloping lower edge and the inner surface of the cover is approximately 15-25 degrees. Specifically, the airflow baffle 58 is configured as a triangular or fan-shaped structure. This structural design allows for adaptive changes in the volume of the fumigation cavity 1a to accommodate users with different leg lengths, while also ensuring the simplicity and aesthetics of the airflow baffle 58.

[0131] In this embodiment, the airflow baffle 58 is disposed inside the fumigation chamber 1a and close to the chamber wall of the fumigation chamber 1a, so that the airflow baffle 58 and the chamber wall can form a guide structure to guide the cover 57 to flip open or close; furthermore, the airflow baffle 58 is disposed off the side edge of the cover 57 to form an abutment portion, which is configured so that the cover 57 can abut against the top of the housing and remain closed when closed, so that the cover 57 fits the housing more compactly when closed, improving the aesthetics.

[0132] Furthermore, the cover plate 57 includes a base and a cover pivotally connected to the base. The base is attached to the housing and located away from the opening in the front wall. The base includes a lower edge that is sealed to the top wall of the housing, forming a sealed connection between the base and the top wall of the fumigation chamber 1a, preventing steam from entering the base and preventing steam from escaping. The cover covers the opening in the top wall of the fumigation chamber 1a, and the base has a pivot hole, while the cover has a pivot portion that matches the pivot hole. Specifically, the cover includes an upper plate and a lower plate that are nested together. The pivot portion is formed on the rear side wall of the lower plate. The pivot portion includes a bent rod and a pivot body perpendicular to the side wall of the bent rod. The bent rod extends rearward from the cover and bends upward to form an upward-opening clearance space, suitable for the cover plate 57 to flip.

[0133] Furthermore, openings are provided on both the top and front walls of the housing, which not only facilitates the user's legs entering the fumigation chamber 1a but also provides ample leg movement space. This allows the user to freely adjust the position of their legs during steaming, such as sitting or lying down. The cover 57 can also cover the top opening, tucking the user's knee joint into the fumigation chamber 1a to ensure effective fumigation. Additionally, a steam baffle 330 adapted to users with different leg lengths is provided at the side opening. This baffle is movably attached to the front wall of the housing via a built-in force spring 34 to change the size of the side opening. The force spring 34 applies force to the steam baffle 330 in a direction that moves it upwards to fit the user's legs. This configuration ensures that the steam baffle 330 remains in contact with the lower side of the user's legs during steaming to prevent steam leakage.

[0134] As shown in Figures 2, 3, and 15, the system also includes a medicine storage mechanism for placing the medicine pack, which is located within the steam channel. Specifically, the medicine storage mechanism includes a hollowed-out medicine box 700, which is detachably attached to the foot pedal assembly 400 for easy access to the medicine pack. The hollowed-out structure of the medicine box 700 increases the contact area between the steam flow and the medicine pack, thereby improving the release effect of the medicine. In this embodiment, the medicine box 700 is located within the steam channel. When the steam flows through the steam channel, the medicinal properties in the medicine pack are guided by the steam and released, thus providing steam treatment to the user's feet and legs, enhancing the steaming effect.

[0135] Furthermore, as shown in Figures 3 and 24, the bottom wall 521 of the fumigation chamber 1a has a water outlet; a water collection box 600 is removably connected to the bottom of the main body 100, and the top wall of the water collection box 600 has a water inlet located below the water outlet; the footrest 410 is located above the water outlet, and a drainage channel is formed between the footrest 410 and the bottom wall 521 of the fumigation chamber 1a, with the bottom wall 521 of the drainage channel inclined towards the water outlet to guide water into the water collection box 600. By adopting the above solution, condensate and sweat generated during fumigation can be smoothly discharged, avoiding the water accumulation problem common in traditional steam baths, ensuring the dryness and hygiene of the equipment. In addition, the footrest 410, located above the water outlet, can also, to some extent, block the upward flow of cold air inside the water collection box 600, ensuring a constant temperature inside the fumigation chamber 1a, thereby ensuring the fumigation effect of the steam on the legs.

[0136] The working principle of the body steam bath device of the present invention is as follows: The steam generator 210 is started to supply steam to the steam chamber 1a; the cover 57 is opened to expose the opening, and the user can then insert their legs into the steam chamber, and then close the cover 57; if the user's leg height is higher than the height of the steam chamber 1a, the cover 57 can be placed directly on the user's legs when closed. At this time, the airflow baffles 58 on both sides of the cover 57 can form a barrier at the opening between the cover 57 and the steam chamber 1a, thereby preventing steam from escaping from the left and right sides of the cover 57. Furthermore, the cover 57 is made of lightweight material, and its movable end is freely adjustable, allowing it to be freely rotated according to the user's leg movements, providing high flexibility; if the user's legs are lower than the height of the steam chamber 1a, the user's legs... The side opening allows the steam chamber 1a to be inserted, at which point the cover 57 can be directly closed on the top of the steam chamber 1a. Furthermore, during steam bathing, the steam baffle 330 at the side opening can move downwards under the pressure of the user's legs, thereby changing the size of the side opening to accommodate users with different leg lengths. When the steam baffle 330 is pressed downwards, the force spring 34 applies force to the steam baffle 330 in a direction that moves it upwards to fit the user's legs, ensuring that the steam baffle 330 remains in contact with the lower side of the user's legs during steam bathing to prevent steam leakage. Through the cooperation of the cover 57 and the steam baffle 330, the volume and opening size of the steam chamber 1a can be flexibly changed, resulting in a better user experience during steam bathing.

[0137] In summary, this invention proposes a novel body steam bath. This steam bath, by introducing a leg length adaptation mechanism 300 and utilizing a movable steam baffle 330 and a force application mechanism, ensures that the steam closely adheres to the lower side of the user's legs, effectively preventing steam leakage. Simultaneously, by providing a protective baffle 37 at the insertion port 1b, it further blocks steam flow to the sensitive area inside the knee joint, protecting user safety. Furthermore, the steam bath of this invention optimizes the design of the footrest assembly 400, employing a combination of a heat insulation plate 44 and a footrest 410, improving the heat insulation performance and comfort of the footrest area, thus enhancing the effectiveness and user experience of the body steam bath.

[0138] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention 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 the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
