[0035] 932—Slider Specific implementation method:

[0036] Reference Figure 1 、 Figure 2 and Figure 3 The steam base assembly includes a base 1, a water box 2, a steam generator 3, a water pump 4 and a fan 5; the steam generator 3, the water pump 4 and the fan 5 are arranged at the bottom of the base 1, and the water box 2 is arranged at the upper part of the base 1 to provide a one-time water supply.

[0037] In this embodiment, the central axis of the base 1 is provided with a cable cavity 11, a sunken water reservoir 12, and a water receiving seat 13, which are connected to the water receiving seat 13. The water box 2 can be inserted upside down on the water receiving seat 13 and fill the water reservoir 12 with water. In other words, the water box 2 provides a fixed amount of water. Once inserted upside down on the water receiving seat 13, the protruding resistance column 131 in the center of the water receiving seat 13 pushes the spring plug 21 at the opening of the water box 2 inward, and water and air will flow in and out along the gap. The water is then injected into the lower water reservoir 12 along the pipe. The capacity of the water box 2 is smaller than that of the water reservoir 12, ensuring that the water will not overflow, while just meeting the design requirements of a steam bath. This is also one of the features of this design, which solves the many inconveniences of the water box 2 providing continuous water supply.

[0038] The cable cavity 11 is located at the front or rear of the base 1 and has a penetrating structure, providing for cable routing between the panel and the underside of the base 1. The base 1 has a raised cover formed on the edge to accommodate abutment 14, while the sunken bottom surface 15 has an inclined structure, with a low front and high back, or high front and low back. A drain hole 16 is provided at the lowest position, and a drawer-style water collection box 17 is located below the corresponding drain hole 16 to facilitate cleaning at the end of the steam bath. A drain port 121 is also provided at the lower position of the water reservoir 12. Both the drain port 121 and the water collection box 17 are accessible from the bottom shell. To this end, the drain port 121 can be designed in the passage connecting to the water box 2, forming a three-way connection.

[0039] Water pump 4 is connected to the lower level of water reservoir 12 and supplies water to steam generator 3. Synchronous control can be easily achieved through electronic control, and the speed of water pump 4 can also be adjusted according to the power of steam generator 3 to achieve a balance between steam production and water consumption, thereby achieving continuous water supply. The steam port of steam generator 3 is connected to the upper space of water reservoir 12; a sealing cover 18 is provided at the open top of water reservoir 12, and a steam outlet 181 is provided on the sealing cover 18; the air outlet of fan 5 is connected to the upper space of water reservoir 12, and the air is mixed with the incoming hot steam and discharged from the steam outlet 181. The upper space of water reservoir 12 is fully utilized to form an air and steam exchange zone, achieving the purpose of temperature regulation and flow increase, and condensed water can also fall directly into the pool.

[0040] Furthermore, an ultrasonic mist generator 6 is installed at the bottom of the water reservoir 12 to enhance the atomization effect and, more importantly, to regulate the temperature. In conjunction with the fan 5, it can produce both high-flow mist and high-concentration, slow-dissipating mist. Furthermore, if essential oils are added to the water in the reservoir, low-temperature atomization can be achieved through ultrasonic waves.

[0041] Refer again Figure 6 、 Figure 7 and Figure 8 An air duct 122 with a common wall is also formed on the inner edge of the water reservoir 12. The upper air outlet 1221 of the air duct faces the pool wall, and the lower air outlet 1222 faces outward and can be connected with the air outlet of the fan 5, so that the incoming wind blows toward the pool wall; a steam inlet 123 is opened on the radial pool wall at the position of the air duct 122, which is connected with the steam port of the steam generator 3 through the steam inlet 123; the sealing cover 18 is formed with a downward deflector 182 corresponding to the steam inlet 123 and the upper air outlet 1221. The lower edge of the deflector 182 is higher than the highest designed water surface, which can press the incoming steam and air to the water surface, and after being evenly mixed with the water mist generated by the ultrasonic mist generator 6, it is discharged upward from the steam outlet 181 to ensure the uniformity of the temperature of the mixed mist.

[0042] Furthermore, the steam outlet hole 181 of the sealing cover is set at the central position, and a windshield 183 is also provided on the axial inner side of the steam outlet hole 181 to prevent the water surface mist from directly rushing out of the steam hole 181, which is also a means of homogenizing.

[0043] Reference Figures 4 to 8 A footbath composed of the above-mentioned steam base assembly also includes: a bottom shell 7, a footrest assembly 8 and an upper cover assembly 9; the steam base assembly is installed on the bottom shell 7 with the help of the base 1, the footrest assembly 8 is placed on the base 1 of the steam base assembly, and the upper cover assembly 9 is covered outside the footrest assembly 8 and locked on the base 1 of the steam base assembly; that is, the associated component of the steam base assembly is the base 1.

[0044] The footrest assembly 8 includes two side enclosures 81 and a foot pedal 82, with the aid of the enclosures 81 to narrow the steam space; the foot pedal 82 is provided with massage rollers 83 and hollow holes 84 distributed for the soles of the feet to allow the mixed steam to rise and fill the upper space.

[0045] The upper cover assembly 9 includes a cover 91, a movable cover 92, and a leg cover 93. The front end of the cover 91 is equipped with a control panel, and the rear end is provided with an opening 911 for inserting the feet. The movable cover 92 can be fitted over the opening 911, providing a complete storage solution. The leg cover 93 slides on a pair of rails 912 on the inner surface of the cover 91, and can move back and forth along the rails 912. The leg cover 93 has an M-shaped double notch 931 on one end facing the opening 911. The M-shaped double notch 931 contacts the legs, forming a relatively close contact, preventing steam leakage and maintaining a high and constant temperature in the basin.

[0046] Furthermore, the front ends of the pair of slide rails 912 are locked to the middle of the cover 91, while the rear ends are suspended. A slider 932 is locked to the middle of the lower surface of the leg cover 93. The two sides of this slider 932 slide and fit onto the pair of slide rails 912, forming a suspended sliding support. During operation, the leg cover 93 can be moved back and forth by hand. Furthermore, to prevent the legs from sagging, support rails 913 are provided on both sides of the inner surface of the cover 91. These rails not only support the edges of the legs, but also serve as travel limits to prevent them from falling out during movement.

[0047] An electric control box 914 is locked on the inner surface of the front end of the cover 91. The bottom of the electric control box 914 is inserted into the upper end of the cable cavity 11 in the steam base assembly. A button 915 protruding from the surface passes through the opening of the cover. The control panel is composed of the button 915 and the indicator light.

[0048] The biggest feature of this foot bath is that a water reservoir 12 is set in the center of the base 1, and a water pump 4 continuously supplies water to an independent steam generator 3. The generated steam returns to the upper part of the water reservoir and mixes with the mist generated by the ultrasonic mist generator 6 set at the bottom of the water reservoir, thereby increasing the amount of mist and achieving the effect of regulating temperature.
