[0049] Among them, each regulating body includes an outer shell, a heat exchange component (not shown) and a fan component (not shown). A heat exchange inner cavity is formed in the outer shell, and an air inlet and an air outlet are formed on the outer shell. The heat exchange component and the fan component are both arranged in the heat exchange inner cavity. The heat exchange component is used to exchange heat with the gas flowing through it, and it can specifically cool the indoor air or heat it.

[0050] The air heater involved in the present application is used to heat indoor air, that is, low-temperature airflow is output as high-temperature airflow after passing through a heat exchange element.

[0051] The heat exchange element is a heating fin arranged in the heat exchange inner cavity, or the heat exchange element is a graphene tube group arranged in the heat exchange inner cavity.

[0052] The heating fins or graphene tube group are externally connected to the power supply line 400 to generate heat, which can be output after exchanging heat with the air flow passing through, thereby playing the role of heating.

[0053] The fan is arranged in the heat exchange cavity and is used to drive the air flow from the air inlet to the heat exchange cavity, and then output from the air outlet after heat exchange by the heat exchange component.

The first end of the cantilever portion 310 is detachably connected to the plug-in portion 204, and the second end of the cantilever portion 310 extends outward in a direction away from the outer side surface 202.

[0057] The size of the plug-in portion 204 is slightly larger than the cantilever portion 310 to improve the stability of the connection between the cantilever portion 310 and the adjustment body, and to prevent the cantilever portion 310 from falling out of the plug-in portion 204 during use.

[0058] refer to Figure 4-Figure 6 In some embodiments of the present application, the cross frame portion 320 is connected to the adjacent cantilever portion 310, and two limiting portions 321 are formed on the cross frame portion 320, and each limiting portion 321 is formed with a notch 322, which is inserted into the corresponding cantilever portion 310 to achieve a detachable connection between the cross frame portion 320 and the corresponding cantilever portion 310.

[0059] refer to Figure 7 In some embodiments of the present application, the number of cantilever portions 310 on the same adjustment body is more than two, and each cantilever portion 310 is horizontally spaced apart and arranged on the corresponding outer side surface 202. More than two limiting portions 321 are formed on the cross frame portion 320, and each limiting portion 321 is formed with a notch 322, which is inserted into the corresponding cantilever portion 310 to realize a detachable connection between the cross frame portion 320 and the corresponding cantilever portion 310.

[0060] Taking the example of three cantilever parts 310 on the same adjustment body, each cantilever part 310 is plugged into the outer side surface 202 at a preset spacing, and the number of cross-frame parts 320 is multiple, which are arranged at intervals along the length direction of the cantilever part 310. The cross-frame parts 320 are arranged perpendicular to the length direction of the cantilever part 310. The cross-frame parts 320 run across each cantilever part 310. There are also three limiting parts 321 on the cross-frame part 320, which are respectively plugged into the cantilever part 310 to realize the connection between the cross-frame part 320 and each cantilever part 310.

[0061] refer to Figure 8 In other embodiments, the number of cantilever portions 310 on the same adjustment body is more than two, and each cantilever portion 310 is horizontally spaced apart on the corresponding outer side surface 202, and the cross frame portion 320 is connected to two adjacent cantilever portions 310. In order to avoid conflict, the two adjacent cross frame portions 320 are staggered. Specifically, two limiting portions 321 are formed on each cross frame portion 320, and a notch 322 is formed on each limiting portion 321. The notch 322 is inserted into the corresponding cantilever portion 310 to achieve a detachable connection between the cross frame portion 320 and the corresponding cantilever portion 310.

[0062] The heater involved in the present application has a support member 300 that can be detachably connected to the adjustment main body, and the cantilever part 310 is detachably connected to the outer side surface 202. A horizontal frame part 320 is installed between the two cantilever parts 310 for drying clothes. Then, the airflow output from the air outlet part of the outer side surface 202 helps to dry the clothes. This provides a reasonable solution to the problem that clothes are not easy to dry after washing during the return of the south wind and the plum rain season in the south.

[0063] In addition, the angle between the adjustment bodies is variable, that is, when working, the two adjustment bodies are in the open state, providing stable support for the entire heater. When stored, the two adjustment bodies are folded toward the middle, the volume of the entire heater is reduced, the footprint is small, and it is easy to store.

[0064] refer to Figure 9 、 Figure 10 In some embodiments of the present application, the intermediate connecting member 100 specifically includes a connecting body 120 and a rotating part 110 rotatably connected to the connecting body 120. The rotating part 110 is connected to the adjusting body one-to-one, and the adjusting body can be rotatably connected to the connecting body 120 under the action of the rotating part 110.

[0065] Specifically, the connecting body 120 is a cylindrical structure, and the rotating portion 110 is a rotating sleeve structure that is sleeved on the outside of the connecting body 120 .

[0066] The intermediate connecting member 100 is externally connected to a power supply line 400 , and the power supply line 400 can be connected to the heat exchange member and the fan member respectively to play a power supply role.

[0067] The rotating portion 110 is rotatably connected to the connecting body 120 , thereby realizing a rotatable connection between the adjusting body and the intermediate connecting member 100 .

[0068] Combine Figure 9 、 Figure 12 In some embodiments of the present application, the adjustment component includes a first adjustment body 210 and a second adjustment body 220, the rotating part 110 includes a first rotating part 111 and a second rotating part 112, the first adjustment body 210 is connected to the first rotating part 111, and the second adjustment body 220 is connected to the second rotating part 112, and the angle formed between the first adjustment body 210 and the second adjustment body 220 is variable.

[0069] The connecting body 120 has limiting ends 130 formed at both ends. The limiting ends 130 are specifically fixed sleeves mounted on both ends of the connecting body 120 . The limiting ends 130 are respectively fixed at both ends of the connecting body 120 to limit the axial position of the rotating part 110 .

[0070] The first rotating portion 111 and the second rotating portion 112 are respectively disposed between the two limiting end portions 130 and rotate within a rotation position formed between the two limiting end portions 130 .

[0071] During installation, one of the limiting ends 130 is first fixed to the connecting body 120 , and the limiting end portion 130 can be connected and fixed to the connecting body 120 by means of a snap connection, a threaded connection, or fasteners.

[0072] After one of the limiting end portions 130 is fixed, the first rotating portion 111 and the second rotating portion 112 are sleeved onto the connecting body 120 , and then the other limiting end portion 130 is fixed.

[0073] A certain amount of rotational friction is formed between the first rotating portion 111 and the second rotating portion 112 and the connecting body 120 to prevent the first adjusting body 210 and the second adjusting body 220 from rotating in the working state and the storage state.

[0074] Reference again Figure 9 In some embodiments of the present application, the first adjusting body 210 and the second adjusting body 220 both include an inner side surface 201, an outer side surface 202 and two end surfaces 203, the air outlet is formed on the outer side surface 202, and the air inlet is formed on at least one end surface 203.

The end surfaces 203 are located at the two ends of the first adjustment body 210 and the second adjustment body 220, that is, between the inner side surface 201 and the outer side surface 202.

[0076] In some embodiments of the present application, the air outlet and the air inlet are grille structures formed on the outer side surface 202 and the end surface 203 respectively.

[0077] The outer side surface 202 and the end surface 203 are both grid structures, which can increase the area of ​​air outlet and air inlet, and improve the heat exchange efficiency.

[0078] In some embodiments of the present application, there are multiple fan components, which are arranged at intervals along the inner side of the air inlet.

[0079] Since the end surface 203 is a long strip structure, in order to improve the air intake efficiency, a plurality of fan components are arranged at intervals along the length direction of the end surface 203 on the inner side of the air inlet portion, which can increase the air intake volume.

[0080] Combine Figure 10 In some embodiments of the present application, an operating portion 150 is provided at the end of the connecting body 120, and the operating portion 150 is a display panel or a control button.
