DETAILED DESCRIPTION

[0020] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and embodiments, so that the implementation process of how the present application applies technical means to solve technical problems and achieve corresponding technical effects can be fully understood and implemented accordingly. The embodiments of the present application and the various features in the embodiments can be combined with each other without conflict, and the technical solutions formed are all within the protection scope of the present application.

[0021] It should be clear that the embodiments described below are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by technicians in the relevant field without making creative work are within the scope of protection of the present application. Example

[0022] This embodiment describes a device for indoor heating using natural ventilation: like Figure 1-Figure 5As shown, a device for indoor heating using natural ventilation includes an air heating device and a shell 22, wherein the air heating device includes a ventilation guide mechanism, an electric heating wire 23, a generator 7, a wind wheel 9 and a buffer storage mechanism; a guide plate 2 is provided inside the shell 22, an air inlet 3 is provided on the guide plate 2, and the wind wheel 9 is installed below the air inlet 3, the input end of the generator 7 and the wind wheel 9 move synchronously, and the generator 7 and the electric heating wire 23 are electrically connected; the buffer storage mechanism includes a sliding plate 10, a transmission gear 8 and a buffer spring 15; the sliding plate 10 is slidably arranged at the bottom end of the shell 22, the transmission gear 8 and the input end of the generator 7 rotate synchronously, and the transmission gear 8 and the sliding plate 10 are meshed for transmission; one end of the buffer spring 15 is fixed to the shell 22, and the other end is fixed to the sliding plate 10.

[0023] The buffering force storage mechanism also includes a sliding column 13, a return spring 12, a slider 14 and an extension fixing block 11; the extension fixing block 11 is fixedly arranged on the side end of the sliding plate 10, the sliding column 13 is fixed to the extension fixing block 11, the slider 14 is slidably connected to the sliding column 13, the return spring 12 is sleeved on the sliding column 13, and one end of the return spring 12 is fixed to the extension fixing block 11, and the other end is fixed to the slider 14. The slider 14 is provided with teeth that mesh with the transmission gear 8.

[0024] The internal connection relationship and working principle of the buffer storage mechanism are as follows: like Figure 1 As shown, when natural wind enters from the top of the housing 22, it passes through the guide plate 2 and drives the wind wheel 9 to rotate, thereby driving the generator 7 to generate electricity. After driving the generator 7 to generate electricity, it drives the electric heating wire to heat, and when the natural wind blows downward, it passes through the electric heating wire at the air outlet and flows out after being heated.

[0025] When the wind volume suddenly increases, the wind wheel 9 drives the generator 7 to operate at high speed, and the transmission gear 8 engages with the slider 14 to push the sliding plate 10 to compress the buffer spring 15, thereby converting excess kinetic energy into elastic potential energy for storage; when the wind volume decreases, the buffer spring 15 releases energy to maintain the stable output power of the generator 7 and avoid the impact of voltage fluctuations on the heating wire 23.

[0026] At the same time, when the air volume is too large, the transmission gear 8 and the sliding plate 10 move relative to each other to the limit (end), and the transmission gear 8 immediately meshes with the teeth on the slider 14 (such as Figure 4 As shown in the figure, when the teeth on the slider 14 are meshed with the transmission gear 8 for transmission, due to the action of the return spring 12, the teeth on the slider 14 will mesh with the teeth on the transmission gear 8 in turn, thereby realizing the protection against transmission overload when the air volume is too large. Example

[0027] This embodiment further describes the ventilation and flow guiding mechanism based on the embodiment 1: The ventilation and diversion mechanism includes a pressure-bearing end head 1, a transmission column 5 and a transmission block 18; the transmission block 18 includes a sliding part and a connecting part, the number of the sliding parts is two, the two sliding parts are fixed by the connecting part, and the connecting part is arranged obliquely; two oblique sliding blocks 19 are arranged at the inner end of the pressure-bearing end head 1, and the two oblique sliding blocks 19 and the two transmission blocks 18 are correspondingly matched; an oblique through groove is arranged in the middle part of the transmission column 5, the connecting part is slidably arranged in the oblique through groove, and the connecting part is fitted with the inclined surface of the oblique through groove.

[0028] The ventilation and air guide mechanism also includes a sliding seat 24, a windshield 6, and a reset spring 16. The pressure end 1 is slidably arranged in the hollow interior of the sliding seat 24. A sliding ring 20 adapted to the sliding of the transmission column 5 is fixed at the bottom end of the sliding seat 24. A notch adapted to the lateral sliding of the transmission block 18 is provided at the side end of the sliding ring 20. The windshield 6 is fixed to the lower end of the transmission column 5. The guide plate 2 is fixed to the side end of the sliding seat 24. A through embedded groove is provided on the guide plate 2. The windshield 6 is adapted to the embedded groove. One end of the reset spring 16 is fixed to the transmission column 5, and the other end is fixed to the pressure end 1. An air outlet slot is provided at the lower end of the housing 22, and the heating wire 23 is installed in the air outlet slot.

[0029] The internal connection relationship and working principle of the ventilation and diversion mechanism are as follows: Through the linkage design of the pressure end 1 and the transmission block 18, when the natural wind pressure changes, the pressure end 1 drives the oblique sliding block 19 to push the transmission block 18, and the wind shield 6 is lifted and lowered through the oblique through slot of the transmission column 5. This structure can dynamically adjust the opening and closing area of ​​the air inlet 3, balance the air volume input under different wind speeds, and avoid unstable heating due to excessive air volume or insufficient power generation due to too little air volume.

[0030] Specifically: When the air volume is large, the pressure-receiving end 1 moves downward along the sliding seat 24. Figure 5 As shown, when the oblique sliding block 19 moves downward, it will squeeze the obliquely arranged transmission block 18, and will push the transmission block 18 from left to right. At this time, due to the inclined connection between the transmission column and the connecting part, when the connecting part moves to the right, the transmission column 5 moves upward, so it can drive the wind shield 6 to move upward. After the wind shield 6 moves upward, it can gradually block the embedded groove on the guide plate 2, so that the wind is concentrated to flow toward the air inlet 3, which can increase the rotation speed of the wind wheel 9 and facilitate the generation of electricity. The advantage of this design is that it can quickly heat the heating wire, thereby quickly heating a large amount of air and increasing the heating effect.
