[0033] 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.

[0034] As Figures 1 to 16As shown in the figure, the utility model provides a large-air-volume and high-speed blowing assembly, which includes a housing 1, a high-pressure air outlet 2 formed on the housing 1, and a blowing assembly installed in the housing 1. The blowing assembly includes multiple groups of independent high-speed fan groups 3 and a high-pressure mixing chamber 4 communicating with each group of the high-speed fan groups 3. The high-pressure mixing chamber 4 communicates with the high-pressure air outlet 2. Generally, the traditional blowing assembly has a single blowing source. During the blowing process in a long air duct, the high-pressure air attenuates greatly, resulting in problems such as slow blowing speed and uneven air outlet. Therefore, the air outlet surface of the traditional blowing assembly is generally relatively small and difficult to make large. In order to overcome the problems existing in large-area air outlet, the utility model sets multiple groups of independent high-speed fan groups 3, and each group of the high-speed fan groups 3 can provide high-speed air. The utility model adopts multiple blowing sources, which can increase the blowing air volume and enlarge the blowing area, and can provide large-area high-speed air. When used as a body dryer, it can dry the body moisture faster and improve the body drying effect. The blowing assembly in the utility model can be used in household appliances, such as installed in the bathroom, shower lamp, warm air blower, body dryer or body drying and warming blower, or electrical equipment such as heaters, fresh air fans, air conditioners, fans for indoor temperature regulation, etc.

[0035] See Figures 1 to 16 , in the above-mentioned embodiment given by the utility model, it further includes that the high-speed fan group 3 includes a fan housing 33 and a high-speed fan 31 installed in the fan housing 33. The fan housing 33 is provided with an air inlet 331 and an air outlet 332, and the air outlet 332 communicates with the high-pressure mixing chamber 4. The air inlet 331 communicates with the outside of the housing 1. The high-speed fan 31 in the utility model is a small-sized 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 a hundred thousand revolutions per minute, with small volume, low noise and high wind speed. The utility model adopts multiple groups of independent high-speed fan groups 3, which can increase the blowing air volume and meet the need for large-area blowing. Adopting a large-area 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 utility model is lower, reducing noise pollution.

[0036] See Figures 1 to 16 , in the above-mentioned embodiment given by the utility model, it further includes that the fan housing 33 in the utility model is composed of a fan cover plate 333 and the inner wall of the high-pressure mixing chamber 4, and the fan cover plate 333 is buckled on the high-pressure mixing chamber 4. The fan cover plate 333 facilitates the installation of the high-speed fan 31. The air outlet 332 is aligned with the high-pressure mixing chamber 4 to blow high-speed air flow into the high-pressure mixing chamber 4, and the high-speed air flow is then blown out through the high-pressure air outlet 2. The above structure is conducive to the external air flow entering the high-pressure mixing chamber 4 and flowing at high speed in the high-pressure mixing chamber 4.

[0037] See Figures 1 to 16 In the above - mentioned embodiment given by the present utility model, it further includes that the high - speed fan group 3 further includes a heating element 32, and the heating element 32 is installed at the air outlet 332 of the fan chamber 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. A plurality of ventilation grooves 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 exactly block the air outlet 332. When the high - speed air flow blown out by the high - speed fan 31 passes through the ventilation grooves, 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.

[0038] See Figures 1 to 16 In the above - mentioned embodiment given by the present utility model, it further includes that the high - pressure mixing chamber 4 is of an annular - pipe - like structure, and the high - speed fan group 3 is installed in the high - pressure mixing chamber 4. In this embodiment, the high - pressure mixing chamber 4 is composed of three arc - shaped mixing chambers connected to each other, and the high - speed fan group 3 is composed of three groups. One group of high - speed fan groups 3 is installed in each arc - shaped mixing chamber. The high - speed fan groups 3 are evenly distributed in the high - pressure mixing chamber 4, making the air supply of the high - speed fan groups 3 more uniform. The high - pressure mixing chamber 4 is annular, quadrilateral or multi - segment broken - line - shaped. In this embodiment, it is of an annular structure, which can provide a larger blowing area and high - speed air flow at the same time. The high - pressure mixing chamber 4 can also be a polygonal structure such as a square or a regular pentagon, or a multi - segment broken - line structure. In the polygonal structure, one group of high - speed fan groups 3 is arranged on each side, that is, each side is supplied with air by one group of high - speed fan groups 3. In the multi - segment broken - line structure, one group of high - speed fan groups 3 is arranged on each broken line, and each broken line is supplied with air by one group of high - speed fan groups 3. Of course, it can also be that two sides or two broken lines are supplied with air by one group of high - speed fan groups 3.

[0039] In the present utility model, the high - speed air blown out 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 continuously accelerate the air flow in the annular air duct, increasing the wind 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.

[0040] See Figures 1 to 16, in the above - mentioned embodiments provided by the present utility model, it further includes that the high - pressure air outlet 2 is arranged at the top of the high - pressure mixing chamber 4. The high - pressure air outlet 2 is composed of multiple long - strip air outlet slits. Multiple air guiding vanes 5 are arranged in the high - pressure mixing chamber 4, and each air guiding vane 5 corresponds to one section of the air outlet slit. The high - pressure air outlet 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 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 high - pressure mixing chamber 4 to guide the high - speed air flow in the high - pressure mixing chamber 4 into the high - pressure air outlet 2. Due to the arrangement of the air guiding vane 5, the air blowing of the high - pressure air outlet 2 is more uniform, improving the air - blowing effect. The air guiding vane 5 can not only change the wind direction but also reduce the wind loss.

[0041] See Figures 1 to 16 , 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 an air duct lower shell 12. The air duct upper shell 11 and the air duct lower shell 12 are buckled together, and their inner cavities form the high - pressure mixing chamber 4. The middle part of the air duct upper shell 11 bulges upward to form a convex ring structure, and the high - pressure air outlet 2 is formed on the convex ring structure. The present utility model installs the high - speed fan group 3 at the lower part of the high - pressure mixing chamber 4, and the upper part of the high - pressure mixing chamber 4 is used for high - pressure mixing.

[0042] See Figures 1 to 16 , in the above - mentioned embodiments provided by the present utility model, it further includes that a plurality of air supply holes are arranged near the high - pressure air outlet 2. The air supply holes are used to supplement the air volume of the high - pressure air outlet 2 and improve the air supply volume.

[0043] See Figures 1 to 16 , in the above - mentioned 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, and a temperature - sensing component wiring terminal 335 is arranged on the outer wall of the fan housing 33. 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 34 to improve the detection effect. Since the high - pressure mixing chamber 4 is a closed structure, in order to improve the air - blowing effect, it is necessary to reduce the gaps. 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 method of external wiring, improving the sealing performance of the high - pressure mixing chamber 4.

[0044] In another embodiment provided by the present utility model, the high-pressure mixing chamber 4 is composed of multiple independent high-pressure mixing chambers. A set of the blower groups 3 is installed in each high-pressure mixing chamber, and each high-pressure mixing chamber 4 communicates with a part of the high-pressure air outlets 2. In this embodiment, the high-pressure mixing chamber 4 and the blower groups 3 form an independent air supply unit, and multiple air supply units are respectively blown out from the high-pressure air outlets 2.

[0045] See Figures 1 to 16 , according to a large-air-volume warm air blower provided by the present utility model, it includes a warm air blower body and a blowing assembly installed in the warm air blower body, and the blowing assembly is the large-air-volume high-speed blowing assembly in the above embodiment. The warm air blower body refers to all components except the blowing assembly, and different warm air blower structures adopt different body structures.

[0046] See Figures 1 to 16 , in the above warm air blower embodiment provided by the present utility model, it further includes a fresh air outlet 6 and a fresh air blowing assembly 7, and the fresh air blowing assembly 7 communicates with the fresh air outlet 6. In the present utility model, two independent working 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 drying system can be used for drying the body moisture and has a drying function. The two blowing assemblies are independently arranged and can work independently or simultaneously according to needs. The present utility model has both the functions of a bath heater and a 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.

[0047] See Figures 1 to 16 , in the above warm air blower embodiment provided by the present utility model, it further includes that the high-pressure air outlets 2 and the fresh air outlets 6 are arranged in an inner and outer ring. In this embodiment, the high-pressure air outlets 2 are located in the outer ring and are of a multi-segment fine slit structure. The fresh air outlets 6 are located in the inner ring and are formed by arranging a plurality of round holes. The above structure can effectively increase the air outlet area and improve the air blowing volume. The fresh air outlets 6 can be used as air supplement holes.

[0048] See Figures 1 to 16, in the above-mentioned hot air blower embodiment provided by the present utility model, it further includes that the fresh air blowing assembly 7 includes a fresh air blower 71 and a fresh air heating element 72. A fresh air passage 61 is provided in the housing 1, and the fresh air passage 61 communicates with the fresh air outlet 6. The fresh air heating element 72 is installed in the fresh air passage 61. The fresh air blower 71 is arranged at the central position, which 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 ventilation is carried out. The fresh air passage 61 surrounds the periphery of the fresh air blower 71, and the fresh air heating element 72 is installed in the fresh air passage 61 and surrounds the periphery of the fresh air blower 71. The above structure is beneficial to heating the high-speed air generated by the fresh air blower 71 and at the same time increases the air outlet area.
