Here, the sectional shape of the first seal member 13 refers to a sectional shape of the first seal member 13 taken along a plane perpendicular to the axial direction of the first seal member 13.

In one embodiment, referring to fig. 4 to 8, at least a portion of the side surface of the first sealing member 13 is a first inclined surface 13b, and the distance between the first inclined surface 13b and the heating element 11 is gradually reduced along the direction in which the opening of the accommodating space 12b enters the accommodating space 12b. That is, the distance between the first inclined surface 13b and the center line of the first sealing member 13 gradually decreases from bottom to top, and the first inclined surface 13b gradually shrinks from bottom to top.

It can be understood that, at least a part of the side surface of the first sealing member 13 is the first inclined surface 13b, so that the first inclined surface 13b plays a role in guiding, so as to conveniently arrange the first sealing member 13 in the accommodating space 12b, and on the other hand, the side wall of the accommodating space 12b can apply an extrusion force perpendicular to the first inclined surface 13b to the first sealing member 13, thereby forming an effect of gathering force, that is, the first sealing member 13 is extruded towards the central line of the first sealing member 13, so that the sealing performance between the first sealing member 13 and the heating body 11 is improved, and further, the sealing performance between the housing 12 and the heating body 11 is improved.

Note that the fact that at least a part of the side surface of the first seal 13 is the first inclined surface 13b means that a part of the side surface of the first seal 13 may be the first inclined surface 13b, or all the side surfaces of the first seal 13 may be the first inclined surfaces 13b. In addition, the fact that the partial side surface of the first sealing member 13 is the first inclined surface 13b means that the partial side surface of the plurality of side surfaces of the first sealing member 13 may be the first inclined surface 13b, for example, when the first sealing member 13 is similar to a rectangular parallelepiped, one side surface, two side surfaces, or three side surfaces of the first sealing member 13 may be the first inclined surface 13b, or a partial region of the same side surface may be the first inclined surface 13b, for example, a region of the side surface close to the top is the first inclined surface 13b, and a region of the side surface close to the bottom is a surface parallel to the axial direction of the first sealing member 13. Of course, the partial region of the same side surface is the case where the partial region of the first slope 13b including the partial side surface of the first seal 13 is the first slope 13b and the partial region including the entire side surface of the first seal 13 is the first slope 13b.

In an embodiment, referring to fig. 4 to 7, the sidewall of the accommodating space 12b has a second inclined surface 12c adapted to the first inclined surface 13b. That is, by setting the side wall of the accommodating space 12b as the second inclined surface 12c, the first sealing member 13 and the housing 12 are in sealing contact with each other through the first inclined surface 13b and the second inclined surface 12c, on one hand, the contact area between the first sealing member 13 and the housing 12 is increased, so that the sealing performance between the first sealing member 13 and the housing 12 is improved, on the other hand, when the side wall of the accommodating space 12b presses the first sealing member 13 downwards, a friction force parallel to the first inclined surface 13b and a pressing force perpendicular to the first inclined surface 13b are generated on the first sealing member 13, the friction force can enable the housing 12 and the first sealing member 13 to be tightly attached together to realize a sealing effect, and the pressing force can press the first sealing member 13 towards the heating element 11, so that the first sealing member 13 and the heating element 11 are tightly attached together to realize a sealing effect, and further, the sealing performance between the housing 12 and the heating element 11 is improved.

It should be noted that, the number of the fasteners 40c and the fastening holes 20c is not limited herein, for example, referring to fig. 1 and fig. 9, the number of the fasteners 40c and the fastening holes 20c is 2, so that the reliability of the connection structure between the outer casing 20 and the inner casing 40 can be improved by matching 2 fasteners 40c and 2 fastening holes 20 c.

In other embodiments, the side wall of the receiving cavity 20a is provided with a clip 40c, and the outer side wall of the inner cover 40 is provided with a clip hole 20c, and the clip 40c is clipped with the clip hole 20c to fix the inner cover 40 on the housing 20.

In still other embodiments, a clamping groove may be formed on a side wall of the accommodating cavity 20a, and a clamp 40c is formed on an outer side wall of the inner cover 40, and the clamp 40c is clamped with the clamping groove to fix the inner cover 40 to the housing 20.

In still other embodiments, a side wall of the accommodating cavity 20a may be provided with a clip 40c, an outer side wall of the inner cover 40 is provided with a clip groove, and the clip 40c is clipped with the clip hole 20c to fix the inner cover 40 on the housing 20.

In one embodiment, referring to fig. 2, the housing 20 is fixedly connected to the inner cover 40. That is, fastening holes may be provided in the outer case 20 and the inner cover 40, and a fastening member 50 is inserted into the fastening holes in the outer case 20 and the inner cover 40 to achieve a fastening connection, thereby facilitating the detachment of the outer case 20 and the inner cover 40.

In one embodiment, the outer shell 20 and the inner cover 40 are connected by snap-fit and fastening to achieve fixation together. For example, the housing 20 is engaged with the inner cover 40 at one side thereof by engaging the engaging protrusion 40c with the engaging hole 20c, and is fastened to the opposite side thereof by the fastening member 50. So, on the one hand, can improve connection structure's between shell 20 and the inner cover 40 reliability, on the other hand, when dismantling, through taking off fastener 50, can deviate from buckle 40c from calorie hole 20c, can dismantle inner cover 40 from shell 20, made things convenient for the dismantlement.

The various embodiments/implementations provided herein may be combined with each other without contradiction.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application are included in the protection scope of the present application.
