Abstract
The utility model relates to a portable electric warmer with a large radiating surface, which comprises: the electric heating tube is a fin electric heating tube, a handle is arranged on the upper portion of the shell, a hot air outlet is formed in the front end of the shell, an electric fan is arranged on the rear portion of the inner side of the shell, an electric fan mesh enclosure 4 is arranged at the rear end of the shell, a large-heat-dissipation-surface diffusion cover 2 is arranged at the hot air outlet and consists of 3-10 horn-shaped cylinders with the same axis, and the calibers of the horn-shaped cylinders are gradually increased from inside to outside to enable a hot air channel to be formed between every two adjacent horn-shaped cylinders. The utility model has the beneficial effects that: because the large radiating surface diffusion cover is arranged, the calibers of the trumpet-shaped cylinders of the large radiating surface diffusion cover are gradually increased from inside to outside to form a hot air channel between two adjacent trumpet-shaped cylinders, the structure enables hot air in the front to be diffused towards the periphery through the hot air channel, the front heated area is greatly increased, and the heating effect is better.
Description
Technical Field
The utility model relates to an electric heater, in particular to a portable electric heater with a large radiating surface.
Background
The portable electric warmer has a bigger and bigger market due to convenient carrying, but the traditional portable electric warmer has a small radiating surface, which affects the warming effect, so that the portable electric warmer with a large radiating surface is necessary to be designed.
Disclosure of Invention
The utility model aims to solve the problems and provides a portable electric warmer with a large radiating surface, which can increase the radiating area of hot air under the condition of unchanged original volume.
The technical scheme adopted by the utility model is as follows: a large radiating surface portable electric warmer comprises: the electric heating tube is a fin electric heating tube, a handle is arranged on the upper portion of the shell, a hot air outlet is formed in the front end of the shell, an electric fan is arranged on the rear portion of the inner side of the shell, an electric fan mesh enclosure 4 is arranged at the rear end of the shell, a large-heat-dissipation-surface diffusion cover 2 is arranged at the hot air outlet and consists of 3-10 horn-shaped cylinders with the same axis, and the calibers of the horn-shaped cylinders are gradually increased from inside to outside to enable a hot air channel to be formed between every two adjacent horn-shaped cylinders.
The included angle between the cylinder surface of the horn-shaped cylinder and the axis is gradually increased from inside to outside.
The lateral surface of the cylinder surface of the horn-shaped cylinder is provided with circular convex surfaces which are uniformly distributed.
The utility model has the beneficial effects that: because the large radiating surface diffusion cover is arranged, the calibers of the trumpet-shaped cylinders of the large radiating surface diffusion cover are gradually increased from inside to outside to form a hot air channel between two adjacent trumpet-shaped cylinders, the structure enables hot air in the front to be diffused towards the periphery through the hot air channel, the front heated area is greatly increased, and the heating effect is better.

Detailed Description
As shown in fig. 1 to 7, the present invention includes: the electric heating device comprises a shell 1, a control switch 3, a fan and an electric heating tube, wherein the electric heating tube is a fin electric heating tube, a handle 11 is arranged at the upper part of the shell, a hot air outlet 12 is arranged at the front end of the shell, an electric fan is arranged at the rear part of the inner side of the shell, and an electric fan mesh enclosure 4 is arranged at the rear end of the shell. As shown in fig. 7, in the present embodiment, the front and rear diameters of the trumpet-shaped tubes from inside to outside are gradually increased, so that a hot air channel 25 is formed between two adjacent trumpet-shaped tubes. The included angle between the cylinder surface of the trumpet-shaped cylinder and the axis 24 is gradually increased from inside to outside. The contained angle of the tube surface of a horn section of thick bamboo 21 and axis 24 is 15 degrees in this embodiment, and the contained angle of the tube surface of a horn section of thick bamboo two 22 and axis is 30 degrees, and the tube surface of a horn section of thick bamboo three 23 and the contained angle of axis are 48 degrees, and this structure makes the hot-blast diffusion of passing through hot air channel in the place ahead to the periphery in the place ahead, makes the place ahead heated area increase by a wide margin, and the heating effect is better. In order to further increase the heat expansion area and the heat dissipation uniformity, uniformly distributed circular convex surfaces 231 are arranged on the outer side surface of the cylinder surface of the horn-shaped cylinder, the circular convex surfaces are part of a spherical surface, and the other corresponding surface 232 of the circular spherical surface is a concave circular surface.
The utility model is not limited to the embodiments described above, but many variations can be made by a person having the basic knowledge in the field to which the utility model pertains without going beyond the inventive idea of the claims, which also falls within the protective scope of the utility model.
