[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0023] This specific embodiment provides an electric heating device and an electric heater to solve the technical problem of poor heat dissipation performance of electric heaters in the prior art.

[0024] The following is an explanation of the embodiments with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the contents of the utility model described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to the solutions required as the utility model described in the claims.

[0025] Reference Figure 1-Figure 4 The utility model provides an electric heating device, including a base 1, a cover 2, a heat dissipation device 4, and a heating device 3, wherein the heating device 3 is installed on the base 1 to provide heat energy. In order to better diffuse the heat energy outward, the cover 2 is covered on the base 1, and the heating device 3 is included in the cover 2, wherein an outlet 21 is provided on the cover 2, and the heat energy included in the cover 2 diffuses outward along the outlet 21. In order to better diffuse the heat energy evenly to the surroundings, the heat dissipation device 4 is arranged above the cover 2, wherein when the heat dissipation device 4 is a rotatable part, the rotating part can realize the exchange and diffusion of heat by the flow of cold and hot air flows, and when the heat dissipation device 4 is a reflecting part, the heat energy is diffused to the surroundings by reflection. With such a configuration, the heat dissipation device 4 can diffuse the heat energy ejected from the outlet 21 evenly to the surroundings, thereby providing the surrounding temperature and improving the heat dissipation performance.

[0026] A further optimization scheme is that the heat sink 4 is a heat reflector, and the side of the heat reflector close to the cover 2 is set to an arc surface, and the center of the arc surface is set on the side of the heat sink 4 away from the cover 2. In this way, the heat energy ejected from the outlet is reflected by the heat reflector, and the heat energy is diffused to the surroundings, thereby increasing the temperature of the space around the base and reducing the heat energy moving upward through the outlet.

[0027] To further optimize the solution, the heat dissipation device 4 can also be a flap wheel or a wind wheel or a wind hood. When the flap wheel or the wind wheel rotates, it can diffuse the heat energy to the surroundings, thereby accelerating the temperature of the space around the base 1. At the same time, when the hot air diffuses, convection of cold and hot gases occurs, thereby driving the wind wheel to rotate, thereby realizing the exchange of cold and hot air flows.

[0028] A further optimization scheme is adopted. In order to increase the heat dissipation efficiency of the heat dissipation device, the cross-sectional area of ​​one end of the cover 2 close to the heat dissipation device 4 is smaller than the side of the cover 2 close to the base 1, and the cross-sectional area of ​​the cover 2 gradually increases from the end close to the heat dissipation device 4 to the other end of the cover 2, forming a cone. In this way, the heat energy ejected from the lower half of the cover 2 can be diffused to the surroundings, and at the same time, relatively less heat energy is diffused to the surroundings through the heat reflection element. The heat energy set on the upper plate part of the cover 2 can be directly ejected onto the heat reflection element, which causes relatively more heat energy to be diffused to the surroundings through the reflective element.

[0029] According to a further optimization scheme, in order to facilitate people to install the heating device, a cavity 11 is provided on the base 1, and the heating device 3 is arranged in the cavity 11, which can facilitate the installation of the heating device and ensure the safety of the heating device during use.

[0030] As a further optimization scheme, in order to increase the heat dissipation effect, outlets 21 are provided on the circumference of the cover 2, so that the heat energy in the cover 2 can be ejected outward evenly.

[0031] A further optimization scheme is provided on the outlet 21 to facilitate adjustment of the angle of heat energy ejected from the outlet 21. Thus, the angle of the blinds can be adjusted, thereby adjusting the angle of heat energy ejection. That is, the blinds on the lower part of the cover 2 eject more heat energy laterally, and the ejected heat energy diffuses to the surroundings. Meanwhile, relatively less heat energy diffuses to the surroundings through the heat reflection element. The blinds on the upper plate part of the cover 2 are angled toward the reflective element. The ejected heat energy can be directly ejected onto the heat reflection element for reflection. This causes relatively more heat energy to diffuse to the surroundings through the reflective element.

[0032] To further optimize the solution, the heating device is a carbon crystal plate heating element. The carbon crystal plate heating element uses far-infrared low-temperature radiation as the main energy transfer method. The product heats up quickly, heats quickly, is safe and reliable, has a long service life, is easy to install, has a beautiful design, and is beneficial to health. This is also the outstanding advantage of the carbon crystal low-temperature radiation heating system. While heating, the carbon crystal electric heating plate radiates far infrared rays, which is medically called "life light waves". Far infrared rays have the effect of improving and preventing and treating various diseases caused by blood circulation and microcirculation disorders.

[0033] The present application document also provides an electric heater, including any of the above-mentioned electric heating devices, so as to facilitate electric heating and heat dissipation.
