In other embodiments, the height difference between the third air inlet and the upper end surface of the heating base in the length direction of the main body may also be in other ranges, and the present invention is not limited to this, as long as it can be ensured that the air flowing through the air inlet channel through the second air inlet 112 and/or the air entering the first gap through the third air inlet can effectively cool and cool the heating base.
In another embodiment of the present invention, the third air inlet is located between the bottom of the receiving chamber and the heating seat of the heating part. That is, in the longitudinal direction of the apparatus (the same as the longitudinal direction of the main body), the gas can flow through the gas inlet channel through the second gas inlet and directly enter the space between the bottom of the housing chamber and the heating seat of the heating part through the third gas inlet, and the heating seat can be cooled and cooled.
Meanwhile, preferably, the second air inlet 112 and the third air inlet 100 are located in a plane perpendicular to the length direction of the heating portion, that is, the second air inlet 112 and the third air inlet 100 are located on the same cross section of the device, so that the air can reliably move around the space around the heating seat, the temperature of the device shell can be reduced better, the problem of the device shell being scalded is improved, and better use experience is achieved.
Referring to fig. 2 in conjunction with fig. 1 and 3, in the present embodiment, the device 1 is provided with a fool-proof member to orient the end of the main body 10 with the receiving portion 11. That is, a fool-proof member is disposed between the main body 10 and the accommodating portion 11, specifically, the cross sections of the main body 10 and the accommodating portion 11 are both rectangular structures, in the cross section, the lengths of two adjacent sides of the main body 10 are different, the side wall 111 of the accommodating portion 11 corresponds to the shape of the main body 10, when the device is installed, the length of each side of the side wall 111 is corresponding to the shape of the main body 10, so that the second air inlet 112 and the third air inlet 100 maintain a fixed relative position in the circumferential direction of the device 1, and the second air inlet 112 and the third air inlet 100 are prevented from being overlapped when the device is installed, and the fool-proof function is provided.
In other embodiments, the cross sections of the main body and the accommodating portion may have other structures, which is not limited in the present invention, and may be reasonably arranged according to actual needs, as long as the relative positions of the second air inlet and the third air inlet in the circumferential direction of the main body are ensured during assembly between the main body and the accommodating portion, that is, the fool-proof function is provided.
While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that the foregoing is a more detailed description of the invention, taken in conjunction with the specific embodiments thereof, and that no limitation of the invention is intended thereby. Various changes in form and detail, including simple deductions or substitutions, may be made by those skilled in the art without departing from the spirit and scope of the invention.
