1 is a schematic view of the overall structure of the present invention. As shown in the figure, a micro-mist sauna apparatus 10 includes a frame 11. A circuit board case 12 is disposed on an inner side surface of the frame 11, and a circuit enclosure 12 is further provided with a surrounding structure. The enclosure frame 13 of the circuit board box 12 is described.

2 is a schematic view of the frame of the present invention mounted on the frame. As shown in the figure, the top of one side of the frame 13 is provided with a first exhaust hole 131. To ensure the strength of the frame 11, in this embodiment, The first exhaust hole 131 is provided in a plurality of long holes instead of being set as one larger hole. A through hole 133 is provided in a lower portion of the enclosure frame 13.

3 and FIG. 4 are schematic diagrams showing the structure of a circuit board box according to the present invention. As shown in FIG. 2A to FIG. 4, a second exhaust hole 122 is disposed on the circuit board case 12 corresponding to the position of the first exhaust hole 131. In order to ensure the strength of the circuit board casing 12, in the present embodiment, the second exhaust hole 122 is provided in a plurality of holes instead of being provided as a larger hole. A lead through hole 123 is provided in a lower portion of the circuit board case 12.

The function of the above structure is that after the steam is sucked into the body through the air inlet of the micro-mist sauna device, since the enclosure frame 13 surrounds the circuit board casing 12, the steam is blocked and steam is prevented from entering the circuit board casing 12, that is, It is said that the enclosure 13 forms a first layer of protection; since the top of one side of the enclosure 13 is provided with the first exhaust hole 131, even a small portion of the steam passes through the tiny between the enclosure 13 and the frame 11 The gap or the opening of the enclosure frame 13 for wiring enters into the enclosure frame 13 and is also discharged to the first exhaust hole 131, that is, the first exhaust aperture 131 forms the first Second layer of protection; even if there is still a small part of the steam Entering the circuit board case 12, because the second exhaust hole 122 is disposed on the circuit board case 12 corresponding to the position of the first exhaust hole 131, the steam will rise upward to the second exhaust hole 122. It is discharged from the circuit board case 12, and is discharged to the enclosure frame 13 through the first exhaust hole 131 on the enclosure frame 13, that is, the second exhaust hole 122 forms a third layer of protection. In this way, steam can be prevented from entering the circuit board box and the steam can be prevented from condensing into dew condensation water after entering the circuit board box, thereby improving product safety.

The lower portion of the circuit board case 12 is provided with a lead through hole 123. The lower portion of the surrounding frame 13 is provided with a through hole 133. Even if steam passes through the lead through hole 123, it enters the circuit board case 12 and condenses into dew condensation water. The dew condensation water may also be discharged to the outside of the enclosure frame 13 through the lead through hole 123 of the circuit board case 12 and the through hole 133 in the enclosure frame 13.

1 and 2, the enclosure frame 13 is a rectangular parallelepiped frame formed by a flat plate 132 having a U-shaped cross section, a side surface 111 of the frame 11, and a top surface 112. The "U"-shaped flat plate 132 is fixed to the side surface 111 and the top surface 112 of the frame 11. That is, the enclosure frame 13 utilizes a top surface 112 and a side surface 111 of a portion of the frame 11 as a top surface and a side surface of the enclosure frame 13, so that even if the steam of the bathroom enters the inside of the circuit board casing 12, the first The vent hole 131 is discharged and then discharged directly to the outside of the frame 11 through the second vent hole, since the circuit board case 12 is mounted in the space formed by the side 111 of the frame 11, so that the steam can be easily discharged to the dry space (ceiling internal).

Since the surrounding frame 13 utilizes the top surface 112 and the side surface 111 of a portion of the frame 11 as the top surface and one side surface of the surrounding frame 13, the steam discharged from the second exhaust hole 122 on the side of the surrounding frame 13 and the surrounding frame 13 The dew condensation water discharged from the lower through hole 133 is directly discharged to the outside of the frame 11, and the space outside the frame 11 is the inside of the ceiling, because the inside of the ceiling is a dry space, so that no external moisture enters the circuit board through the frame 11. Inside the box 12.

3 and 4, the circuit board case 12 includes a cover 121 and a case base 124. The cover 121 and the case base 124 are integrally formed in a hinge structure. When integrally formed in the form of a hinge structure, the connection of the leads can be performed by opening the cover 121. Moreover, the gap between the cover 121 and the case base 124 can be prevented from being formed by the split cover 121 and the case base 124, and the connection between the cover 121 and the case base 124 can be prevented. It functions to seal the connection cover 121 and the case base 124, improving the waterproof and anti-steam performance.

A peripheral edge of the cover 121 of the circuit board case 12 is provided with a turn-to-close circuit board case 12 The protruding ribs 125 protruding in the direction, the peripheral edge of the box base 124 is provided with a recess 126 for the insertion of the protruding ribs 125. After the protruding ribs 125 are inserted into the recesses 126, the connection gaps formed when the cover 121 is engaged with the box base 124 and connected are shielded to double the waterproof and steamproof functions.

Since the cover 121 and the case base 124 of the circuit board case 12 are integrally formed in the form of a hinge structure in this embodiment, the protruding ribs 125 and the recesses 126 are provided in addition to the hinge structure. The other three sides can be. If the cover 121 and the cartridge base 124 are not integrally formed in a hinged configuration, the projection ribs 125 and the recesses 126 are respectively provided at the peripheral edges of the cover 121 and the four sides of the peripheral edge of the cartridge base 124.

Fig. 5 is a schematic cross-sectional view showing the overall structure of the present invention. As shown in Fig. 5, the first exhaust hole 131 is provided with a waterproof rib 136. The waterproof rib 136 is vertically disposed upward from the bottom 137 of the first exhaust hole 131 to block a portion of the first exhaust hole 131. Even if water enters the frame 11 from the outside of the frame 11, the water is blocked by the waterproof rib 136, and cannot enter the circuit board case 12 directly through the second vent hole 122 and the first vent hole 131, thereby improving safety.

Referring to Figures 1 and 3, a "U" shaped handle 16 is disposed on the bottom surface of the circuit board casing 12. Thus, when the board needs to be repaired, the board casing 12 can be easily withdrawn from the enclosure frame 13 by merely lifting the "U" shaped handle 16.

Fig. 6 is a schematic view showing the lead connection before accommodating the circuit board case, and Fig. 7 is a view showing the arrangement of the lead wires after accommodating the circuit board case. As shown in FIG. 6 and FIG. 7, since the circuit board case 12 and the electrical components in the micro-mist sauna device are connected by the lead 15, they are first placed in the circuit board case 12 and placed in the enclosure frame 13, so that the connection is made. The electrical components and the leads 15 of the circuit board box 12 must be additionally reserved to facilitate the pulling of the leads 15, and after the circuit board case 12 is placed in the surrounding frame 13, a separately reserved length of the lead 15 can be accommodated. In the interior of the "U" shaped handle 16, the leads 15 are distributed without being scattered so as not to affect the mounting of the panel, which facilitates the mounting and dismounting of the circuit board case 12 and also improves safety.
