[0032] To clearly illustrate the solutions in the present utility model, the following preferred embodiments are given and described in detail in conjunction with 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.

[0033] As Figures 1 to 16As shown in the figure, a multifunctional warm air blower provided by the utility model includes a housing 1, an annular air outlet structure formed on the housing 1, and a blowing assembly installed in the housing. The annular air outlet structure includes an annular body drying air outlet structure 2 and an annular fresh air outlet structure 6. The blowing assembly includes a body drying blowing assembly 3 and a fresh air blowing assembly 7. The body drying blowing assembly 3 communicates with the annular body drying air outlet structure 2, and the fresh air blowing assembly 7 communicates with the annular fresh air outlet structure 6. In the utility model, two sets of independent body drying systems and fresh air systems are provided. The fresh air system can be used for replacing fresh air and heating air, and has the functions of a traditional bath heater. The body drying system can be used for drying the moisture on the body and has a body drying function. The two blowing assemblies are independently arranged and can work independently or simultaneously according to needs. The utility model has both the functions of a bath heater and a body drying function, is more convenient to use, and has richer functions. It not only has the functions of heating and air replacement in the bathroom, but also saves the use of towels and is more hygienic and clean.

[0034] See Figures 1 to 16 , in the above-mentioned embodiment given by the utility model, further included is that the annular body drying air outlet structure 2 and the annular fresh air outlet structure 6 are arranged in an inner and outer ring. In this embodiment, the annular body drying air outlet structure 2 is located on the outer ring and is a multi-segment fine slit structure. The annular fresh air outlet structure 6 is located on the inner ring and is formed by arranging a plurality of round holes. The above structure can effectively increase the air outlet area and improve the air blowing volume.

[0035] See Figures 1 to 16 , in the above-mentioned embodiment given by the utility model, further included is that the fresh air blowing assembly 7 includes a fresh air fan 71 and a fresh air heating element 72. A fresh air passage 61 is provided in the housing 1. The fresh air passage 61 communicates with the annular fresh air outlet structure 6, and the fresh air heating element 72 is installed in the fresh air passage 61. The fresh air fan 71 is arranged at the central position and includes a fresh air motor and a fan blade driven by the fresh air motor. The high-speed air generated by the fan blade enters the fresh air passage 61 after being heated by the fresh air heating element 72. If heating is not required, the fresh air heating element 72 does not work and only fresh air replacement is performed. The fresh air passage 61 surrounds the periphery of the fresh air fan 71, and the fresh air heating element 72 is installed in the fresh air passage 61 and surrounds the periphery of the fresh air fan 71. The above structure is beneficial to heating the high-speed air generated by the fresh air fan 71 and at the same time increases the air outlet area.

[0036] See Figures 1 to 16, in the above embodiments provided by the present utility model, it further includes that the fresh air heating element 72 includes a heating tube 721 and multiple fins arranged on the heating tube 721. The fins include large fins 722 and small fins 723, and the large fins 722 and the small fins 723 are arranged at intervals. The fresh air heating element 72 in the present utility model is circular, so that it can surround the fresh air fan 71. The height of the small fins 723 is less than the height of the large fins 722. The fins can increase the heating area, but if the fin density is too large, it is not conducive to air circulation. The present utility model sets a structure combining the large fins 722 and the small fins 723, which not only increases the heating area, but also reduces the resistance of the fins to the air, facilitating air circulation.

[0037] See Figures 1 to 14 , in the above embodiments provided by the present utility model, it further includes that the body drying blowing assembly 3 includes a high-speed fan 31 and a heating element 32. Multiple arc-shaped air ducts 4 are arranged in the housing 1, and a set of the body drying blowing assembly 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 annular body drying air outlet structure 2 communicates with the annular air duct. The high-speed fan 31 in the present utility model is a small high-speed fan. Such high-speed fans can refer to the fan structure used in a hair dryer, and it has the ability to blow high-speed air. The rotation speed of the high-speed fan 31 is as high as more than one hundred thousand revolutions per minute, with a small volume, low noise, and high wind speed. The present utility model adopts multiple sets of independent body drying blowing assemblies 3, which can increase the blowing volume and meet the need for large-area annular blowing. Adopting a large-area annular blowing structure can dry the body moisture more quickly, improve the body drying effect, and overcome the problem of slow speed of traditional body dryers. At the same time, the overall noise of the present utility model is lower, reducing noise pollution.

[0038] See Figures 1 to 14 , in the above embodiments provided by the present utility model, it further includes that the arc-shaped air ducts 4 are 2 - 6 sections, and the body drying blowing assemblies 3 are 2 - 6 groups. In this embodiment, the arc-shaped air ducts 4 are three sections, and the blowing assemblies 3 are three groups. A set of the body drying blowing assembly 3 is installed in each arc-shaped air duct 4 to independently provide high-speed air flow for each arc-shaped air duct 4. In the case of providing large-area blowing, it can also have a relatively high high-speed air flow to meet the purpose of quickly drying the body moisture.

[0039] In the present utility model, the high-speed air blown by the high-speed fan group 3 blows along the tangential direction of the wind direction of the high-pressure mixing chamber. The three high-speed fans 31 accelerate the air flow in the annular air duct in a relay manner to increase the wind pressure. So that there is no negative pressure area in the entire high-pressure mixing chamber, and the high-speed air blown out from the high-pressure air outlet is more uniform.

[0040] The dry body annular air outlet structure in the present utility model can be a circular, quadrilateral or other polygonal structure. Each side is provided with an independent air blowing component and an air duct structure, adopting a multi-section combined structure to increase the air 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 air blowing area. Each independent air duct is provided with a set of dry body air blowing components, and different air ducts can be opened according to needs to work, meeting different functions of drying hair or drying the body.

[0041] See Figures 1 to 14 , in the above-mentioned embodiment given by the present utility model, it further includes that a fan chamber 33 for installing the dry body air blowing component 3 is arranged in each arc-shaped air duct 4. The fan chamber 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 chamber 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, and the fan cover plate 333 facilitates the installation of the air 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 high speed in the annular air duct.

[0042] See Figures 1 to 14 , in the above-mentioned embodiment given by the present utility model, it further includes that the annular dry body air outlet structure 2 is composed of a plurality of strip-shaped air outlet slits, and a plurality of air guiding vanes 5 are arranged in the annular air duct. The annular dry body air outlet structure 2 of the present utility model is circular as a whole and is composed of one section of air outlet slit after another, which can provide a large area of high-speed air flow. The air guiding vane 5 is a curved tongue-shaped structure as a whole, and it extends into the annular air duct to guide 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 annular dry body air outlet structure 2 blows more evenly, improving the air blowing effect.

[0043] See Figures 1 to 14 , in the above-mentioned embodiment given 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 volume of each section of the air outlet slit more uniform and improving the air blowing effect.

[0044] See Figures 1 to 14, in the above embodiments provided by the present utility model, it further includes that the housing 1 comprises an air duct upper housing 11 and the air duct lower housing 12, the air duct upper housing 11 and the air duct lower housing 12 are buckled together, and the drying and blowing assembly 3 and the annular air duct are arranged in the inner cavity formed by the air duct upper housing 11 and the air duct lower housing 12. The middle part of the air duct upper housing 11 bulges upward to form a convex ring structure, and the annular air outlet structure is formed on the convex ring structure.

[0045] See Figures 1 to 14 , in the above 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 comprises a circular ring outer shell 321 and a heating element 322 installed in the circular ring outer shell 321, and a plurality of 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, and it can just block the air outlet 332. When the high-speed air flow blown out by the high-speed fan 31 passes through the ventilation slots, it is heated by the heating element 322. With the above structure, the heating effect is better. The heating element 322 is a PTC heating element.

[0046] See Figures 1 to 14 , in the above embodiments provided by the present utility model, it further includes that a temperature sensing component installation platform 334 is arranged on the inner wall of the fan housing 33, a temperature sensing component wiring terminal 335 is arranged on the outer wall of the fan housing 33, and the wiring terminal 335 passes through the fan housing 33 and is connected to the temperature sensing component on the installation platform 334. The temperature sensing 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, the gaps need to be reduced. The wiring terminal 335 of the present utility model directly passes through the fan cover 333 to realize the connection of internal devices and the connection mode of external wiring, thereby improving the sealing performance of the annular air duct.

[0047] In summary, the above content is only the embodiments of the present utility model, which are only used to illustrate the principle of the present utility model and are not used to limit the protection scope of the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
