[0033] The following will describe in detail some embodiments of the present utility model with reference to the accompanying drawings. Without conflict, the features in the following embodiments can be combined with each other.

[0034] Please refer to Figures 1 to 7 As shown, the present utility model provides a clean and hygienic lower limb steam bath device, including a steam generator 2, a main body 1 defining a fumigation chamber 11 inside, and a cover plate 8 attached to the top of the main body 1. A leg insertion opening for the lower limbs to extend into is jointly defined between the cover plate 8 and the front wall of the main body 1. The steam generator 2 is attached to the rear side of the main body 1 and conveys high-temperature steam into the fumigation chamber 11 during use. A foot steaming device 3 for steaming the feet is arranged at the bottom of the fumigation chamber 11, and the foot steaming device 3 is detachably combined with the main body 1. Wherein, a foot support structure 32 for supporting the feet in the fumigation chamber 11 is arranged at the top of the foot steaming device 3, and a steam channel 11a for steam to flow through is formed inside.

[0035] The foot steaming device 3 is detachably combined with the main body 1, which is convenient for taking out the foot steaming device 3 from the fumigation chamber 11 for cleaning to keep the foot steaming device 3 clean and hygienic. Further, a steam channel 11a for steam to flow through is formed inside the foot steaming device 3. The steam channel 11a is formed by the interval between the foot steaming device 3 and the bottom wall of the main body 1. When the steam enters the steam channel 11a, it can spread evenly to ensure that the steam can evenly and comprehensively cover the foot steaming device 3, realizing comprehensive high-temperature disinfection and improving the health experience of users. In addition, adopting the above design of the steam channel 11a can also make the steam generated by the steam generator 2 reach the foot steaming device 3 along the shortest path, reducing the heat loss generated during the flow of the high-temperature steam, ensuring the temperature of the high-temperature steam, and ensuring the effect of high-temperature disinfection of the foot steaming device 3 by the high-temperature steam. Optionally, the temperature of the steam can reach above 50 °C. Further, the temperature of the steam can reach 65 °C. During disinfection, the foot steaming device 3 is continuously disinfected by the high-temperature steam. Preferably, the time is maintained at about 30 minutes, which can effectively kill about 80% of the viruses and ensure the hygiene of the foot steaming device 3. Further, when necessary, the temperature of the steam can also reach about 100 - 120 °C to ensure the high-temperature disinfection effect of the foot steaming device 3.

[0036] There is a gap between the foot steaming device 3 and the inner wall of the fumigation chamber 11, so that the steam in the steam channel 11a flows through this gap to the fumigation chamber 11 and flows from all around the foot steaming device 3 to the fumigation chamber 11. During the process of overflowing and flowing outwards, it can also disinfect the outer side of the periphery of the foot steaming device 3, ensuring a comprehensive disinfection effect. In addition, in order to guide the steam to evenly and comprehensively cover the foot steaming device 3, the bottom wall of the fumigation chamber 11 is provided with positioning ribs 6 spaced left and right. The positioning ribs 6 extend in the front-rear direction and form a guiding channel therebetween to guide the steam to enter the interior of the foot steaming device 3 from the middle and disperse around, ensuring the disinfection effect of the high-temperature steam on the foot steaming device 3. This will be further described below.

[0037] The top of the foot steaming device 3 is configured with a foot support structure 32 for supporting the feet in the fumigation chamber 11. With this structural design, it can effectively support the user's feet, ensuring that the feet are stably placed during the steam bath and improving the steam bath effect. Further, the foot support structure 32 is configured such that there is a gap through which steam can pass between the feet and the foot steaming device 3. With such a design, it can ensure that the soles of the feet can also come into contact with the steam, and during the flow of the steam, it can also improve the steam bath effect of the feet.

[0038] As Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 As shown, the foot support structure 32 includes a plurality of massage protrusions. The plurality of massage protrusions are distributed on the top of the foot steaming device 3 and can form multi-point support for the feet, ensuring the stable placement of the feet; the plurality of massage protrusions can be laid on the top of the foot steaming device 3 in a uniform manner or partially laid on the top of the foot steaming device 3. The specific laying method is flexible and diverse. In this embodiment, the plurality of massage protrusions are distributed on the top of the foot steaming device 3 at positions roughly corresponding to the acupoints on the soles of the feet. With such a structural design, when the feet are placed on the foot steaming device 3, the plurality of massage protrusions can roughly correspond to the acupoints on the soles of the feet respectively, so as to stimulate the acupoints on the feet while steaming the feet, thereby improving the steam bath effect of the feet.

[0039] As Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 、 Figure 7As shown in the figure, the foot steaming device 3 includes a footrest plate 31. The footrest plate 31 includes a top wall portion and a plurality of side wall portions. The top wall portion of the foot steaming device 3 is inclined, and its inclination direction is gradually downward toward the front side of the main body 1. The foot support structure 32 is coupled to the top wall portion. Adopting this structural design conforms to the ergonomic design, enabling users to enjoy a more comfortable experience during the steam bath. At the same time, the inclined top wall design can ensure more sufficient contact between the user's feet and the foot support structure 32, more effectively stimulating the acupoints on the soles of the feet and achieving a better steam bath effect. Further, a foot-shaped groove 31a similar to the shape of the foot is provided on the inclined top wall. The foot-shaped groove 31a is symmetrically arranged left and right to guide the placement of the feet. Further, the foot support structure 32 is disposed in the left and right foot-shaped grooves 31a. Preferably, thin-walled protrusions with a spiral structure are formed at the bottom of the left and right foot-shaped grooves 31a, which can increase the friction between the foot steaming device 3 and the feet, and can also reduce the contact area between the feet and the top wall portion, having a function of anti-scald protection. In addition, in addition to high-temperature sterilization of the footrest plate 31 with high-temperature steam, a silver ion antibacterial coating is provided on the footrest plate 31, further improving the sterilization and disinfection effect inside the fumigation chamber 11 and ensuring the cleanliness and hygiene of the steam bath device.

[0040] A steam inlet 31b is formed on the rear wall of the plurality of side wall portions of the footrest plate 31, and steam outlets 31c are formed on the left and right side walls of the plurality of side wall portions. A steam channel 11a is defined between the steam inlet 31b and the steam outlets 31c. Among them, the steam inlet 31b can be provided on the left side or the right side of the rear wall, or in the middle position of the rear wall, or at any position on the rear wall, as long as the steam can enter the steam channel 11a. In this embodiment, the steam inlet 31b is provided in the middle of the rear wall. The steam outlets 31c are formed on the left and right side walls of the plurality of side wall portions. It can be that the left side wall forms the steam outlet 31c, or the right side wall forms the steam outlet 31c, or both the left and right side walls are provided with steam outlets 31c. In this embodiment, the left and right side walls of the footrest plate 31 are both provided with steam outlets 31c. A mesh structure is configured at the steam outlet 31c, or the steam outlet 31c is formed by arranging a plurality of through holes 34a in an array, or the steam outlet 31c is formed by fences arranged at intervals front and back. However, the present invention is not limited thereto. By adopting such a design, the steam in the steam channel 11a can be evenly dispersed when passing through the steam outlet 31c, so as to evenly flow to the fumigation chamber 11 and improve the steam bath effect. Preferably, in order to reduce the influence of the steam outlet 31c on the strength of the left and right side walls, a reinforcing portion is provided at the edge of any one of the steam outlets 31c, thereby ensuring the support strength of the left and right side walls.

[0041] As Figure 2 、 Figure 3, Figure 6 and Figure 7 As shown in Figure 6 and Figure 7 , specifically, a steam passage 11a is defined between a steam inlet 31b and a steam outlet 31c. The steam inlet 31b is provided in the middle of the rear wall, and the steam outlets 31c are respectively formed on the left and right side walls. During steam bath or disinfection, steam enters the steam passage 11a through the steam inlet 31b, and then is evenly distributed in the steam passage 11a to heat the foot steaming device 3. By heating the foot steaming device 3, disinfection is achieved or the temperature of the foot steaming device 3 is increased, thereby indirectly heating the feet, improving the steam bath effect of the lower limb steam bath device on the feet. The steam outlets 31c being provided on the left and right side walls enables the steam to flow out from both sides of the foot steaming device 3, avoiding flowing directly towards the feet and thus preventing scalding of the feet. Moreover, flowing out from both sides can make the steam spread more evenly, thereby better steaming the lower limbs of the user.

[0042] As Figure 2 、 Figure 3 and Figure 5 As shown in Figure 2 , Figure 3 and Figure 5 , further, the steam inlet 31b is configured as a "door"-shaped inlet, which cooperates with two positioning ribs 6 spaced left and right to form a positioning and guiding structure for guiding the footrest device to be installed in the fumigation chamber 11 and forming a stable support for the footrest device. Also, a part of the steam passage 11a is formed between the two positioning ribs 6, guiding the steam to enter the interior of the footrest plate 31 from the middle and then disperse from the middle to both sides, ensuring that the footrest device is heated more evenly and better improving the steam bath effect during the steam bath. The cross-section of the positioning rib 6 is square, which can not only ensure the strength of the positioning rib 6 but also enable the positioning rib 6 to play a supporting role in supporting the foot steaming device 3.

[0043] As Figure 2 、 Figure 3 and Figure 7As shown, a lining plate 34 is disposed inside the foot steaming device 3. The lining plate 34 can support the internal space of the foot steaming device 3 to maintain the overall stability of the footrest plate 31. Moreover, the lining plate 34 can also play a role in blocking, preventing steam from directly flowing against the top wall of the footrest plate 31, which may cause the temperature of the top wall of the footrest plate 31 to be too high and scald the feet, thus playing a protective role. Further, the lining plate 34 is spaced from the top wall of the footrest plate 31, separating the interior of the foot steaming device 3 vertically into a heat collection chamber 33 and the steam channel 11a. The lining plate 34 is provided with through holes 34a to communicate the inside of the heat collection chamber 33 with the steam channel 11a. With such a design, while preventing the temperature of the top wall of the footrest plate 31 from being too high and scalding the feet, it can also limit the flow rate of the steam in the steam channel 11a into the heat collection chamber 33 through the through holes 34a, allowing the steam to slowly enter the heat collection chamber 33 and gradually heat up, ensuring that the top wall part of the foot steaming device 3 is at a suitable temperature, so as to better slowly heat the user's feet without worrying about scalding, and improving the comfort of the steam bath. And the steam located in the heat collection chamber 33 can also exchange heat with the steam in the steam channel 11a through the through holes 34a, thus ensuring that the temperature in the heat collection chamber 33 is at an appropriate temperature. Preferably, the aperture size of the through holes 34a is set to allow steam to flow in but not with too large or too fast a flow rate. In this embodiment, the aperture of the through holes 34a can be 4 - 8 mm. Of course, there can also be other aperture sizes, such as larger than 8 mm or smaller than 4 mm, which can be reasonably adjusted according to the size of the foot steaming device 3 and the heat collection chamber 33. Further, a plurality of through holes 34a are provided and distributed on the lining plate 34, enabling the steam to enter from multiple positions and ensuring the uniformity of the internal temperature. Preferably, the setting position of the through holes 34a can be coordinated with the foot support structure 32, that is, the through holes 34a can be located directly below the massage protrusions. The massage protrusions are of a hollow structure, allowing the steam to quickly enter the interior of the massage protrusions and heat them, so that the massage protrusions have a better effect when stimulating acupoints. Preferably, the massage protrusions are made of a flexible material, such as silica gel, and the top of the massage protrusions is formed as a round head, which will not dig into the feet while stimulating the acupoints on the sole, improving the effect of the steam bath.

[0044] As Figure 3As shown in the figure, a first limiting member 41 and a second limiting member 51 are respectively arranged on the front and rear sides of the foot steaming device 3. The front and rear sides of the foot steaming device 3 are limited simultaneously by the first limiting member 41 and the second limiting member 51 to ensure the stability of the foot steaming device 3. Further, at least one of the second limiting member 51 and the first limiting member 41 is configured as an elastic buckle. For example, both the first limiting member 41 and the second limiting member 51 are elastic buckles, or the first limiting member 41 located at the rear side is configured as an elastic buckle; or the second limiting member 51 located at the front side is configured as an elastic hook. However, the present invention is not limited thereto. In this embodiment, the second limiting member 51 is used as an elastic buckle for illustration.

[0045] The first limiting member 41 is configured as an abutting protrusion extending backward, and the abutting protrusion can be arranged in the middle or any single side at the rear side of the foot steaming device 3. Of course, two, three, four, etc. of such abutting protrusions can also be provided. In the embodiment, there are two abutting protrusions which are respectively arranged at the left and right ends at the rear side of the foot steaming device 3, and a limiting groove 42 for the abutting protrusion to be embedded is correspondingly formed at the rear side of the bottom wall of the main body 1, so as to limit and fix the rear side of the foot steaming device 3.

[0046] The second limiting member 51 is configured as an elastic buckle, which is arranged at the middle position at the front side of the foot steaming device 3; and a receiving seat for accommodating the elastic buckle is jointly defined between the footrest plate 31 and the lining plate 34. The elastic buckle includes a clamping buckle body and a return spring. The return spring is installed between the clamping buckle body and the receiving seat. The clamping buckle body is provided with a pressing protrusion and a clamping protrusion 52 which are arranged at intervals up and down and in parallel. Among them, the clamping protrusion 52 can be embedded into a clamping groove arranged at the front side of the bottom wall of the main body 1, and the pressing protrusion is suitable for being pressed by a user's finger to push the clamping buckle body to move backward in parallel in the receiving seat, so that the clamping protrusion 52 is away from the clamping groove, so as to take out the foot steaming device 3 from the fumigation cavity 11, which is convenient for disassembly and assembly.

[0047] As Figure 4 and Figure 5 shown in the figure, a detection device 7 for detecting the foot steaming device 3 is further arranged in the main body 1. The detection device 7 is configured to be able to emit a prompt signal when the foot steaming device 3 is not installed in the set position. Designed in this way, it can be detected whether the foot steaming device 3 is installed in place to ensure the use safety. An induction protrusion is arranged at the front end bottom of the foot steaming device 3. During installation, the induction protrusion can contact the induction part on the detection device 7, so as to detect the foot steaming device 3. Optionally, the detection device 7 can adopt existing products, such as a pressure detection device, a gravity detection device, etc. The present invention is not limited thereto.

[0048] As described above, it is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
