The temperature measuring device 450 can detect the temperature of the FPC flexible circuit board 420 and feed back to the main circuit board, so that the temperature can be conveniently controlled. In this embodiment, the temperature measuring device 450 is a negative temperature thermistor, and has excellent accuracy. In other embodiments, other common temperature sensing elements may be used instead.
The upper and lower ends of the overclad tube 430 are secured within the atomizer housing with a peek high temperature resistant plastic 470, respectively.
Referring to fig. 4 to 5, the second aspect of the present invention provides a nebulizer, which includes a housing 100, a battery 130, and a main circuit board 150 in addition to the heating structure 400, wherein the heating structure 400, the main circuit board 150, and the battery 130 are disposed in the housing 100, and the battery 130 is electrically connected to the main circuit board 150.
Referring to fig. 6 to 9, the atomizer further includes an upper cover 120, the upper cover 120 is provided with a slide mechanism 200, the slide mechanism 200 includes a slide cover 210, the slide cover 210 includes a cover plate 212 provided on an upper surface of the upper cover 120 and a connection part 214 fixedly connected with the cover plate 212, the connection part 214 extends into the housing 100 through a through hole 122 of the upper surface of the upper cover 120, a side surface of the upper cover 120 is provided with a sliding rail 124, the slide mechanism 200 further includes a sliding shaft 220, the sliding shaft 220 is connected to the connection part 214 of the slide cover 210 and can slide along the sliding rail 124, a length of the sliding rail 124 is adapted to a length of the through hole of the upper surface of the upper cover 120, and a size of the cover plate 212 is larger than the through hole 122 of the upper surface of the upper cover so that the through hole 122 can be completely covered, and the cover plate 212 is 0.5mm to 1mm higher than the upper surface of the upper cover 120 so that the cover plate 212 is not in friction contact with the upper surface of the upper cover 120.
The cover plate 212 and the connection portion 214 of the slider 210 are integrally formed. In this embodiment, two sliding shafts 220 penetrate through the connecting portion 214 of the sliding cover, two ends of the sliding shafts 220 are transversely spanned on two opposite side walls of the upper cover 120, and two ends of the sliding shafts 220 are accommodated in the sliding rails 124. The sliding shaft 220 is a stainless steel shaft. In this embodiment, the housing 100 and the upper cover 120 have two flat and parallel side walls, so that a flat sliding rail 124 is conveniently provided.
It should be understood that this embodiment only provides a more preferable solution that is convenient to assemble, in other embodiments, the sliding shaft may not penetrate the sliding cover, and the sliding shafts may be respectively disposed at positions corresponding to the sliding rails on two sides of the connecting portion of the sliding cover, so as to achieve the purpose of this patent. In addition, the sliding rail of the present embodiment is a through hole, and in other embodiments, the sliding rail may be a groove, so long as the end of the sliding shaft can be accommodated.
In the present embodiment, the sliding shaft 220 penetrates through the two side walls of the upper cover 120 and the connecting portion 214 of the sliding cover, because the side walls of the upper cover 120 are inserted into the housing 100, the sliding shaft 220 penetrating through the sliding rail 124 can be restricted from moving by the inner wall of the housing 100, so that the sliding shaft 220 cannot be separated.

The torsion spring mechanism 240 includes a torsion spring 242, wherein upper and lower free ends of the torsion spring 242 extend straight to form an acute angle, a first free end of the torsion spring 242 is hung on a protrusion 215 on the lower surface of the connecting portion 214, a second free end of the torsion spring 242 is hung on a protrusion 125 on the lower surface of the upper cover 120, the torsion spring 242 is in a pressed state after both ends are hung, and when the slide cover 210 slides to an intermediate position between a cover closing position and a cover opening position, the torsion spring 242 is pressed maximally. When the sliding cover 210 slides to the two extreme positions of the full open cover and the full close cover, the compression of the torsion spring 242 is minimum, so that the sliding cover 210 tends to walk towards the two extreme positions, and the purpose of stabilizing the states of the two extreme positions of the open cover and the close cover can be achieved.
But are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that modifications and improvements can be made without departing from the spirit of the invention, such as combining different features of the various embodiments, which are all within the scope of the invention.
