[0023] Below, detailed description is made to the embodiments of the present application with reference to the drawings, so as to make the purpose, technical scheme and advantages of the embodiments of the present application more clear. Obviously, the described embodiments are part of the embodiments of the present application, but not all the embodiments.

[0024] Therefore, the detailed description of the embodiments of the present application provided in combination with the drawings below is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present application.

[0025] Embodiment 1

[0026] As shown in the drawings, Figures 1-4 The linear air warmer in the present embodiment comprises a shell part, a blowing part and an air outlet part arranged in the shell part. The shell part comprises a bottom shell 10 and an upper cover 20. The upper cover 20 is provided with two air inlets 21 and one air outlet. The bottom shell 10 is provided with an air exchange opening 11. The blowing part comprises a first fan 31, a first air duct arranged outside the first fan 31, a second fan 32 and a second air duct arranged outside the second fan 32. The air outlet part is arranged on part of the first air duct and the second air duct. The position of the air outlet part corresponds to the position of the air outlet.

[0027] The air outlet part comprises a support frame and a heating body, such as a PTC heating element, arranged in the support frame. Both of them are conventional structures in the field and will not be further limited here.

[0028] The first air duct comprises a first main body 331 and a first air outlet body 332 connected in series. The first main body 331 does not completely surround the first fan 31. The first air outlet body 332 gradually narrows and extends to the second air duct. The first air duct is connected to the air outlet part only.

[0029] The second air duct comprises a second main body 341, a second air outlet body 342 and a third air outlet body 343 connected in series. The second main body 341 does not completely surround the second fan 32. The second air outlet body 342 gradually narrows and is connected to the first air outlet body 332. The third air outlet body 343 is arranged on one side of the second air outlet body 342 and extends to the inner wall of the bottom shell 10, and surrounds the air exchange opening 11. Thus, the second air outlet body 342 is connected to the air outlet part, and the third air outlet body 343 is connected to the air exchange opening 11. That is, the second air duct is connected to the air outlet part and the air exchange opening 11 at the same time. The air body switching between the air outlet part and the air exchange opening 11 can be realized by switching the rotating direction of the second fan 32.

[0030] The third air outlet body 343 comprises a first folded edge 3431 and a second folded edge 3432. The first folded edge 3431 is connected to one side of the second air outlet body 342, and the second folded edge 3432 is bent and connected to the inner wall of the bottom shell 10. There is a space between the first folded edge 3431 and the second fan 32. The first folded edge 3431 has a curved surface towards the side of the second fan 32. The first folded edge 3431 is generally U-shaped.

[0031] The first air outlet body 332 and the second air outlet body 342 are provided with a partition plate 35, which separates the first air outlet body 332 and the second air outlet body 342, thereby separating the air outlet channels of the first fan 31 and the second fan 32 to achieve separate air exhaust.

[0032] Therefore, the support frame is arranged above the first air outlet body 332 and the second air outlet body 342, and the heating body is arranged above the first air outlet body 332 on one side of the partition plate 35. When hot air is provided, only the air force provided by the first fan 31 is heated to achieve hot air exhaust. When natural air exhaust is performed, the two motors can be used simultaneously.

[0033] The air outlet position of the upper cover 20 is provided with a grid net body 41, a plurality of connecting plates 42 are inserted and arranged on the grid net body 41, and a plurality of tooth bodies 421 are protrudingly arranged on the connecting plates 42. The tooth bodies 421 are inserted into the grid net body 41 to achieve connection and fixation. The connecting plates 42 can abut against the support frame to achieve positioning.

[0034] Embodiment 2

[0035] In this embodiment, the first folded edge 3431 is provided with a rib plate one 362 and a rib plate two 363, forming a triangular structure, and the ends connected by the two are connected to the support plate one 361. The support plate one 361 is arranged between the second folded edge 3432 and the second air outlet body 342, and is arranged near the first folded edge 3431 in the second air outlet body 342, thereby supporting the position of the first folded edge 3431 and avoiding the impact deformation of the first folded edge 3431 during the repeated switching of the fan direction.
