[0051] This embodiment provides a heater, which is configured to deliver hot air to an indoor space to adjust the indoor temperature.

[0052] Reference Figures 1 to 3 The heater includes a frame 100 and a heater body 200. The frame 100 includes a base 110, a stand 120 is arranged on the base 110, and the heater body 200 is arranged on the stand 120. The heater body 200 is configured to deliver hot air to the indoor space.

[0053] In some embodiments, the stand 120 is rotatably disposed on the base 110, and the delivery direction of the hot air is adjusted by rotating the stand 120.

[0054] In some embodiments, the heater body 200 is rotatably disposed on the stand 120, and the delivery direction of the hot air is adjusted by the rotation of the heater body 200.

[0055] In some embodiments, the heater body 200 includes a housing 210, and a mounting cavity (not shown) is disposed in the housing 210. The housing 210 is provided with an air inlet 211 and an air outlet 212, the air inlet 211 and the air outlet 212 are disposed opposite to each other, and the air inlet 211 and the air outlet 212 are respectively connected to the mounting cavity.

[0056] The heater body 200 further includes a wind wheel device 220 . Figure 42 is a structural diagram of the wind wheel device 220. The installation cavity is a cylindrical cavity structure, and the wind wheel device 220 is arranged in the installation cavity. When the wind wheel device 220 rotates, air enters the installation cavity through the air inlet 211, and the air flows through the wind wheel device 220 for heat exchange to become hot air, and the hot air flows into the indoor space through the air outlet 212, thereby adjusting the temperature of the indoor space.

[0057] The wind wheel device 220 includes a driving part 310, a first mounting part 330, a heating plate 320 and the like.

[0058] Specifically, the driving part 310 includes a rotating shaft, on which the first mounting part 330 is fixedly disposed. Figure 8 1 is a structural diagram of the first mounting portion 330. The first mounting portion 330 is a disc-shaped structure. A heating sheet 320 is fixedly arranged on the first mounting portion 330. The heating sheet 320 extends along the length direction L of the mounting cavity. A plurality of heating sheets 320 are distributed at intervals along the circumference of the first mounting portion 330 to form a cross-flow fan structure. The heating sheet 320 is equivalent to the fan blade of the cross-flow fan structure.

[0059] The driving part 310 is turned on, the shaft rotates, the shaft drives the first mounting part 330 to rotate synchronously, the first mounting part 330 drives the heating plate 320 to rotate synchronously, and the cross-flow fan structure rotates.

[0060] When the heater is working, the cross-flow fan structure rotates, the heating plate 320 generates heat, and air enters the installation cavity through the air inlet 211. The air flows through the heating plate 320, and the air exchanges heat with the heat generated by the heating plate 320 to become hot air. The hot air flows into the indoor space through the air outlet 212, thereby adjusting the temperature of the indoor space.

[0061] The multiple heating sheets 320 form a cross-flow fan structure, which generates air volume by its own rotation, has low air resistance during rotation, reduces noise, and does not require an additional fan. The multiple heating sheets 320 are evenly distributed, and heat and heat are evenly distributed.

[0062] In some embodiments, the heating sheet 320 includes a heating sheet body, the surface of which is coated with a graphene coating (not shown), and the graphene coating generates heat when electricity is applied.

[0063] The heating sheet 320 not only plays the role of a fan blade, but also plays the role of dissipating heat. Utilizing the heating property of graphene when it is powered on, a graphene coating is coated on the surface of the heating sheet 320. When air flows through the heating sheet 320, the air can fully contact the graphene coating, thereby fully exchanging heat, which helps to improve the heat exchange efficiency and heat dissipation uniformity.

[0064] In some embodiments, reference Figure 3 and Figure 4The driving part 310 includes a motor 311. First mounting parts 330 are respectively provided at both ends of the cross-flow fan structure, one of the first mounting parts 330 is fixedly connected to a first rotating shaft 312, the first rotating shaft 312 is connected to a power output end of the motor 311, and the other first mounting part 330 is fixedly connected to a second rotating shaft 313, the second rotating shaft 313 is rotatably connected to the housing 210.

[0065] The motor 311 is started, driving the first rotating shaft 312 to rotate, the first rotating shaft 312 drives the first mounting portion 330 to rotate synchronously, the first mounting portion 330 drives the heating plate 320 to rotate synchronously, and the second rotating shaft 313 also rotates synchronously, thereby realizing the rotation of the cross-flow fan structure.

[0066] The heater body is arranged on the frame 100 in a vertical position, and the wind wheel device 220 is arranged in a vertical position in the housing 210. The motor 311 is fixedly arranged on the bottom wall of the housing 210, and the second rotating shaft 313 is rotatably connected to the top wall of the housing 210. The upper and lower ends of the cross-flow fan structure are rotatably installed, thereby realizing the rotatable installation of the cross-flow fan structure.

[0067] The cross-flow fan structure is arranged in a vertical posture in the shell 210, facing the air inlet 211 and the air outlet 212, so that the air entering the installation cavity can fully exchange heat with the heating plate 320, and the hot air after heat exchange flows out from the air outlet 212, thereby improving the heat exchange efficiency and heat dissipation uniformity.

[0068] In some embodiments, the first rotating shaft 312 and the second rotating shaft 313 are energized to supply power to the first mounting portion 330 , and the first mounting portion 330 transfers the electrical energy to the heating sheet 320 .

[0069] The first rotating shaft 312 and the second rotating shaft 313 not only play the role of the installation shaft, but also play the role of conducting electricity, which is equivalent to a conductive rotating shaft. The first rotating shaft 312 and the second rotating shaft 313 transmit the electric energy to the first installation part 330, and the first installation part 330 transmits the electric energy to the heating plate 320, so that each heating plate 320 is evenly powered, so that each heating plate 320 heats evenly, thereby improving the uniform heat dissipation effect of the heater body.

[0070] In some embodiments, reference Figure 5 Each first mounting portion 330 is provided with a conductive portion 380, and the conductive portion 380 is laid along the surface of the first mounting portion 330.

A first mounting hole 331 is provided on the first mounting part 330, and a second mounting hole (not shown) is provided on the conductive part 380. The first mounting hole 331 is directly connected to the second mounting hole for mounting the shaft. Taking the mounting of the first rotating shaft 312 as an example, the first rotating shaft 312 is inserted into the corresponding first mounting hole 331 and the second mounting hole.

[0072] The setting of the conductive part 380, on the one hand, serves to strengthen the structural strength of the first mounting part 330; on the other hand, the conductive part 380 helps to improve the conductivity of the first mounting part 330, thereby ensuring that each heating plate 320 can receive electricity, and further enabling each heating plate 320 to be powered and generate heat.

[0073] The conductive part 380 is made of copper, which has a better conductive effect. The first mounting part 330 is made of galvanized sheet.

[0075] The first heat dissipation part 351 is fixedly sleeved on the first rotating shaft 312. The second heat dissipation part 352 is fixedly sleeved on the second rotating shaft 313. The first heat dissipation part 351 and the second heat dissipation part 352 have the same structure, and a plurality of tooth structures arranged at intervals are arranged on the outer peripheral wall, that is, a concave-convex structure is formed on the outer peripheral wall, which helps to improve the heat dissipation efficiency.

[0076] The first heat dissipation portion 351 and the second heat dissipation portion 352 are made of aluminum, which has a better heat dissipation effect.

The specific principle of brush power supply is prior art and will not be described in detail herein.

[0079] A second bearing 372 is disposed on the top wall of the housing 210, and the second bearing 372 is connected to the second rotating shaft 313.

[0081] The distance between the two first mounting parts 330 is relatively long, and the heat generating sheet 320 is a long strip structure. A plurality of second mounting parts 340 are arranged between the two first mounting parts 330 to provide auxiliary support for the heat generating sheet 320, thereby improving the installation reliability of the heat generating sheet 320 and preventing the heat generating sheet 320 from vibrating, deforming and the like during the rotation of the cross-flow fan structure.

[0082] In some embodiments, Figure 7 The figure is a structural diagram of the heating sheet 320. One side surface of the heating sheet 320 is a concave arc surface 321, and the other side surface of the heating sheet 320 away from the concave arc surface 321 is a convex arc surface 322. The heating sheet 320 is equivalent to the fan blade of the cross-flow fan structure. The arc surface design of the heating sheet 320 helps to increase the air volume.
