When the cover 30 is completely coupled to the housing 20, the cover 30 and the outer wall 21 are subjected to stress in the vertical direction and can be brought into close contact with each other while being deformed.

The sealing protrusion 35 can be inserted into the sealing groove 225. The sealing protrusion 35 can be made of an elastic material. For example, the sealing protrusion 35 can be manufactured from rubber or silicone. When the cover 30 is coupled to the housing 20, the sealing protrusion 35 comes into contact with the upper end of the inner wall 22 within the sealing groove 225, and is subjected to upward stress and can change its shape. When the cover 30 is coupled to the housing 20, the sealing protrusion 35 may fit tightly into the sealing groove 225. The second cover part 32 may be in close contact with the upper end of the inner wall 22 .

The sealing protrusion 35 may protrude downward from the second cover part 32. The sealing groove 225 may be recessed downward from the upper end of the inner wall 22 .

The shape of the sealing protrusion 35 is deformed, and the sealing protrusion 35 is able to completely fill the sealing groove 225 and come into close contact with the sealing groove 225.

Therefore, the cover 30 can be coupled to the housing 20 by rotating in one direction and moving downward. Furthermore, it is possible to airtightly seal the gap between the cover 30 and the housing 20 and prevent air or foreign matter from flowing into the coil arrangement space 25 through the gap between the cover 30 and the housing 20. Furthermore, failure of the heating coil 15 can be prevented.

The male screw 316 engages with the female screw 216 and rotates in one direction, allowing the cover 30 to move downward. The cover 30 can move downward and press the inner wall 22 and the outer wall 21 downward.

Therefore, the cover 30 can be coupled to the housing 20 by rotating in one direction and moving downward. Furthermore, it is possible to airtightly seal the gap between the cover 30 and the housing 20 and prevent air or foreign matter from flowing into the coil arrangement space 25 through the gap between the cover 30 and the housing 20. Furthermore, failure of the heating coil 15 can be prevented.

The restriction protrusion 326b can protrude outward from the outer peripheral surface of the cover 30. The restriction protrusion 326b may protrude outward from the outer peripheral surface of the second cover part 32. The restriction protrusion 326b may be one of a plurality of restriction protrusions spaced apart from each other along the circumferential direction. The limiting protrusion 326b may be disposed above the male thread 326. When the cover 30 rotates in one direction, the limiting protrusion 326b can also rotate in one direction.

A stopper 216b may be formed in the housing 20 around the opening. The stopper 216b may be located adjacent to the female thread 216. The stopper 216b may be placed above the female thread 216.

The stopper 216b can provide elastic force in one direction. The stopper 216b can be said to be a second stopper 216b. The second stopper 216b may have the same or similar shape to the first stopper 215a.

When the cover 30 is rotated and the male thread 326 and the female thread 216 are fastened, the limiting protrusion 326b can pass over the stopper 216b and contact or engage the end of the stopper 216b. If the limiting protrusion 326b exceeds the stopper 216b, the stopper 216b may contact the limiting protrusion 326b and provide a repulsive force in one direction. The stopper 216b can prevent the cover 30 from rotating in the other direction by providing a repulsive force to the limiting protrusion 326b.
