[0030] To clearly illustrate the solution in the present utility model, the following preferred embodiments are given and described in detail with reference to the accompanying drawings. The following description is essentially only exemplary and is not intended to limit the application or use of the present disclosure. It should be understood that in all the drawings, corresponding reference numerals represent the same or corresponding components and features.

[0031] As Figures 1 to 14 shown, a ring-shaped blowing heater provided by the present utility model includes a housing 1, a ring-shaped air outlet structure 2 formed on the housing 1, and a blowing assembly 3 installed in the housing 1. The blowing assembly 3 includes a high-speed blower 31 and a heating element 32. A plurality of arc-shaped air ducts 4 are provided in the housing 1, and a set of the blowing assemblies 3 is installed in each arc-shaped air duct 4. All the arc-shaped air ducts 4 are connected together to form an annular air duct, and the ring-shaped air outlet structure 2 communicates with the annular air duct. The high-speed blower 31 in the present utility model is a small high-speed blower. Such high-speed blowers can refer to the blower structures used in hair dryers, and they have the ability to blow air at high speeds. The rotation speed of the high-speed blower 31 is as high as more than a hundred thousand revolutions per minute, with a small volume, low noise, and high wind speed. The present utility model adopts multiple sets of independent blowing assemblies 3, which can increase the air volume and meet the need for large-area annular blowing. By adopting a large-area annular blowing structure, the body moisture can be dried more quickly, improving the drying effect and overcoming the problem of slow speed of traditional dryers. At the same time, the overall noise of the present utility model is lower, reducing noise pollution.

[0032] See Figures 1 to 14, in the above-mentioned embodiment provided by the present utility model, it further includes that the arc-shaped air duct 4 is divided into 2 to 6 segments, and the blowing component 3 is 2 to 6 groups. In this embodiment, the arc-shaped air duct 4 is divided into three segments, and the blowing component 3 is three groups. One group of the blowing component 3 is installed in each segment of the arc-shaped air duct 4 to independently provide high-speed air flow for each segment of the arc-shaped air duct 4. When increasing the large-area blowing, it can also have high-speed air flow with a relatively high speed, meeting the purpose of quickly drying the body moisture.

[0033] The annular air outlet structure in the present utility model can be a circular, quadrilateral or other polygonal structure. An independent blowing component and air duct structure are arranged on each side. A multi-segment combined structure is adopted to increase the blowing area. Of course, the present utility model can also adopt a plurality of mutually independent air ducts arranged side by side or connected to each other to increase the blowing area. A group of blowing components is arranged in each independent air duct, and different air ducts can be opened for work according to needs to meet different functions of hair drying or body drying.

[0034] See Figures 1 to 14 , in the above-mentioned embodiment provided by the present utility model, it further includes that a fan housing 33 for installing the blowing component 3 is arranged in each segment of the arc-shaped air duct 4. The fan housing 33 is provided with an air inlet 331 and an air outlet 332. The air inlet 331 communicates with the outside of the housing 1, and the air outlet 332 communicates with the arc-shaped air duct 4. The fan housing 33 in the present utility model is composed of a fan cover plate 333 and the inner wall of the arc-shaped air duct 4. The fan cover plate 333 is buckled on the arc-shaped air duct 4. The fan cover plate 333 facilitates the installation of the blowing component 3. The air outlet 332 is aligned with the arc-shaped air duct 4 to blow high-speed air flow into the arc-shaped air duct 4, and the high-speed air flow is then blown out through the annular air outlet structure. The above structure is conducive to the air flow outside the annular air duct entering the annular air duct and flowing at a high speed in the annular air duct.

[0035] In the present utility model, the high-speed air blown by the high-speed fan group 3 blows along the tangential direction of the air flow in the high-pressure mixing chamber. The three high-speed fans 31 accelerate the air flow in the annular air duct continuously in a relay manner to increase the air pressure. So that there is no negative pressure area in the whole high-pressure mixing chamber, and the high-speed air blown out from the high-pressure air outlet is more uniform.

[0036] See Figures 1 to 14, in the above - mentioned embodiments provided by the present utility model, it further includes that the annular air - outlet structure 2 is composed of multiple long - strip air - outlet slits, and multiple air - guiding vanes 5 are arranged in the annular air duct. The annular air - outlet structure 2 of the present utility model is circular as a whole and is composed of one - section - by - one - section air - outlet slits, which can provide a high - speed air flow with a large area. The air - guiding vane 5 is a bent tongue - shaped structure as a whole. It extends into the annular air duct and guides the high - speed air flow in the annular air duct to the annular air - outlet structure. Due to the arrangement of the air - guiding vane 5, the air - blowing of the annular air - outlet structure 2 is more uniform, improving the air - blowing effect.

[0037] See Figures 1 to 14 , in the above - mentioned embodiments provided by the present utility model, it further includes that each air - guiding vane 5 corresponds to one section of the air - outlet slit. The air - guiding vane 5 can increase the air - blowing volume of each section of the air - outlet slit, making the air - blowing volumes of each section of the air - outlet slit more uniform and improving the air - blowing effect.

[0038] See Figures 1 to 14 , in the above - mentioned embodiments provided by the present utility model, it further includes that the housing 1 includes an air - duct upper shell 11 and the air - duct lower shell 12. The air - duct upper shell 11 and the air - duct lower shell 12 are buckled together, and the blowing assembly 3 and the annular air duct are arranged in the inner cavity formed by the air - duct upper shell 11 and the air - duct lower shell 12. The middle part of the air - duct upper shell 11 bulges upward to form a convex - ring structure, and the annular air - outlet structure is formed on the convex - ring structure.

[0039] See Figures 1 to 14 , in the above - mentioned embodiments provided by the present utility model, it further includes that a heating element 32 is installed at the air - outlet 332 of the fan housing 33. The heating element 32 includes a circular - ring outer shell 321 and a heating element 322 installed in the circular - ring outer shell 321. Multiple ventilation slots are formed on the heating element 322. The overall shape of the heating element 32 is the same as that of the air - outlet 332, which can just block the air - outlet 332. When the high - speed air flow blown by the high - speed fan 31 passes through the ventilation slots, it is heated by the heating element 322. With the above - mentioned structure, the heating effect is better. The heating element 322 is a PTC heating element.

[0040] See Figures 1 to 14, in the above-mentioned embodiments provided by the present utility model, it further includes that a temperature-sensitive component installation platform 334 is arranged on the inner wall of the fan housing 33, and a temperature-sensitive component terminal 335 is arranged on the outer wall of the fan housing 33. The terminal 335 passes through the fan housing 33 and is connected to the temperature-sensitive component on the installation platform 334. The temperature-sensitive component on the installation platform 334 includes a fuse and a thermostat. The installation platform 334 is located on the air inlet side of the heating element 32 to improve the detection effect. Since the annular air duct is a closed structure, in order to improve the blowing effect, it is necessary to reduce the gaps. The terminal 334 of the present utility model directly passes through the fan cover 333 to realize the connection of internal components and the connection method of external wiring, thereby improving the sealing performance of the annular air duct.
