The utility model relates to the field of hot air blowers, in particular to a pressurized high-speed hot air blower.

Background Art

The five-in-one hot air comb hair dryer is a hairdressing tool that combines multiple functions. Its structure and functional uses are mainly reflected in the following aspects:

Structurally, a five-in-one hot air comb hair dryer typically consists of a main body, similar to a traditional hair dryer, but equipped with a specialized comb. The comb is often detachable or adjustable to suit different user needs. The main body also contains a heating element, a fan, and a motor to drive the fan, generating hot air.

In terms of functional use, the five-in-one hot air comb hair dryer has the following functions: 1) Blowing function, similar to a conventional hair dryer, can generate wind flow to help dry the hair quickly. 2) Hot air styling, the hot air generated by the electric heating element can quickly heat the hair, making it easier to shape, helping users to create various hairstyles. 3) Straightening function, the design of the comb part allows the wind force to be evenly distributed on the hair, helping to straighten the hair and reduce frizz. 4) Curling function, some models of the five-in-one hot air comb hair dryer also have a curling function. Through the special comb design and thermal effect, you can easily curl up natural and long-lasting curls. 5) Hair care function, some high-end models of the five-in-one hot air comb hair dryer also have a hair care function, through constant temperature technology or negative ion technology, to reduce heat damage and protect hair health.

In summary, the five-in-one hot air comb hair dryer is a hairdressing tool that integrates blowing, styling, straightening, curling and hair care, and is suitable for use at home or in professional hairdressing places.

The main body of a five-in-one hot air comb hair dryer is equipped with an air duct, housing the heating element, fan, and motor. Air inlets and outlets are also provided, communicating with the duct. To ensure a comfortable grip, conventional hair dryers typically use a straight-cylinder body or a structure that tapers gradually along the tail. This structure limits the air intake of conventional hair dryers, resulting in a small air volume. This limited air volume makes it difficult to effectively increase the overall wind speed and output power of the product. Furthermore, this limited air volume creates a certain amount of wind resistance within the duct, which in turn generates a certain amount of noise.

Utility Model Content

The purpose of the present utility model is to solve the above defects and provide a pressurized high-speed hot air blower, which increases the diameter of the air inlet end so that the internal air duct of the air inlet end and the internal air duct of the gripping part are combined to form a large air inlet cavity structure which gradually decreases from large to small, thereby improving the wind speed and output power of the product as a whole, and solving the technical problem in the prior art of designing a smaller air inlet cavity resulting in poor wind speed and output power.

The purpose of this utility model is achieved by the following methods:

The booster high-speed hot air blower includes a casing and an electronic control component arranged inside the casing. The electronic control component includes a main control circuit board, an integrated high-speed brushless motor with fan blades, a power supply and a heating frame. The high-speed brushless motor, the power supply and the heating frame are all electrically connected to the main control circuit board. An air duct is left inside the casing. The tail of the casing is the air inlet end, the air inlet end is covered with a tail cover, and an air inlet connected to the air duct is provided on the side and/or the tail end surface of the tail cover. The front of the casing is the air outlet end, and the air outlet end is provided with an air outlet connected to the air duct. The heating frame, the high-speed brushless motor and the main control circuit board are all arranged in the air duct and are arranged from the air outlet end along the direction of the air inlet end. The middle part of the casing is a grip portion. The diameter of the air inlet end is larger than the diameter of the grip portion, and the diameter of the air inlet end gradually decreases along the direction of the grip portion, so that the air duct near one end of the air inlet gradually decreases in inner diameter along the end away from the air inlet.

Furthermore, the power supply is a power cord for an external power source, the power cord extends outward along the rear end surface of the tail cover, and a fixing frame for mating and tightening the power cord is provided at the rear end of the tail cover.

Furthermore, the outer periphery of the air outlet is provided with snap-on teeth or slots for quickly coupling with various styling heads. Specifically, the various styling heads may be anti-scald curling irons, air nozzles, smoothing combs, or hair-sucking combs. These anti-scald curling irons, air nozzles, smoothing combs, or hair-sucking combs can all be quickly coupled and clipped into the outer periphery of the air outlet, achieving a quick connection with the air outlet. Once mounted and connected, they can be combined with the hot air blower of the present invention to achieve the corresponding styling effects.

Furthermore, an insulating tube is provided on the periphery of the heating frame, and the insulating tube and the high-speed brushless motor are docked and installed through a tube sleeve, and the air duct passes through the high-speed brushless motor, the tube sleeve and the interior of the insulating tube in sequence.

Furthermore, the housing is composed of an upper shell and a lower shell, and the inner walls of the upper shell and the lower shell are provided with retaining ribs for pairing and pressing the high-speed brushless motor, the cylinder sleeve, and the heat-insulating cylinder. The upper shell and the lower shell can be matched and fastened by snaps or screws.

Furthermore, a filter is provided at one end of the high-speed brushless motor close to the air inlet, and an air inlet net corresponding to the position of the air inlet is provided on the inner side of the tail cover.

Furthermore, the main control circuit board is electrically connected to a negative ion generator located inside the air inlet. The negative ion generator can emit over 20 million negative ions when in operation. When the device is turned on, the negative ion generator is set to operate continuously, preventing static electricity in the hair and making it softer and more lustrous.

Furthermore, the main control circuit board is also electrically connected to the main control panel and the adjustment panel, and the surface of the casing is provided with control buttons and working indicator lights corresponding to the positions of the main control panel and the adjustment panel.

The beneficial effects produced by the present invention are as follows: the diameter of the air inlet end gradually decreases along the direction of the gripping portion, so that the internal air duct of the air inlet end is combined with the internal air ducts of the gripping portion and the air outlet end to form a structure of a large air inlet cavity that gradually decreases from large to small. By increasing the diameter of the air inlet end, the air intake volume is significantly increased, a higher wind pressure is formed, and the air intake volume of the high-speed brushless motor is increased at the same time, so that it can reach the optimal working state. Compared with products in the prior art that use high-speed brushless motors of the same power, the structure of the present invention that increases the internal cavity of the air outlet end can improve the wind speed and output power of the product as a whole. At the same time, due to the increase in the air intake volume, the resistance of the air duct can be reduced, and the wind flow in the air duct can be smoother, thereby achieving the technical effect of reducing noise.

DETAILED DESCRIPTION

The present invention will be described in further detail below with reference to the accompanying drawings and specific implementations.

In this embodiment, referring to Figures 1 to 4 , the specifically implemented pressurized high-speed hot air blower includes a housing and an electronic control assembly disposed within the housing. The electronic control assembly includes a main control circuit board 18, an integrated high-speed brushless motor 16 with fan blades, a power supply, and a heating frame 14. The high-speed brushless motor 16, the power supply, and the heating frame 14 are all electrically connected to the main control circuit board 18. The main circuit board 18 is also electrically connected to a main control panel 19 and an adjustment panel 20. The surface of the housing is provided with control buttons and working indicator lights corresponding to the positions of the main control panel 19 and the adjustment panel 20. In this embodiment, the main control panel 19 includes a push switch 21 and a cold air button 22. The push switch 21 is used to turn on the power and turn off the battery. The cold air button 22 is used to switch to cold air mode. The adjustment panel 20 includes a temperature adjustment button 23 and a wind speed adjustment button 24.

An air duct is left inside the housing. The rear end of the housing serves as the air inlet. A tail cover 7 is provided on the air inlet, and air inlets 8 that communicate with the air duct are provided on the side and rear end surfaces of the tail cover 7. As shown in FIG1 , the air inlets 8 of this embodiment are a plurality of neatly and evenly distributed long strips. The power supply is a power cord 4 for an external power supply. The power cord 4 is electrically connected to the main control circuit board 18 via a rotating tail box 5. The power cord 4 extends outward along the rear end surface of the tail cover 7, and a fixing bracket 6 for mating and compressing the power cord 4 is provided at the rear end of the tail cover 7. The main control circuit board 18 is also electrically connected to a negative ion generator 12, which is located inside the air inlet.

The front part of the casing is the air outlet end, which is provided with an air outlet communicated with the air duct, as shown in Figures 3 and 4. The periphery of the air outlet end is provided with teeth or slots for quickly matching and connecting various styling heads. The various styling heads can specifically be anti-scalding curling irons, air nozzles 3, smooth combs or hair-absorbing combs. The anti-scalding curling irons, air nozzles 3, smooth combs or hair-absorbing combs can all be quickly matched and snapped into the periphery of the air outlet end to achieve quick connection with the air outlet end. After installation and connection, the corresponding styling effect can be achieved by combining with the hot air blower of the present invention. As shown in Figures 1 and 2, a circular air nozzle 3 is installed on the periphery of the air outlet end. The circular air nozzle 3 can directly blow out hot air, so that it has a blowing function, which is similar to a conventional hair dryer and can generate wind flow to help quickly dry the hair.

The heating frame 14, the high-speed brushless motor 16, and the main control circuit board 18 are all arranged in the air duct and arranged from the air outlet end to the air inlet end. The outer periphery of the heating frame 14 is provided with an insulating tube 13, which can provide good thermal insulation to prevent heat from being transferred to the housing. The insulating tube 13 and the high-speed brushless motor 16 are docked and installed via a tube sleeve 15. One end of the heating frame 14 is fixedly installed in the tube sleeve 15 and is fixed by the tube sleeve 15. The air duct passes through the interior of the high-speed brushless motor 16, the tube sleeve 15, and the insulating tube 13 in sequence. As shown in Figure 4, the housing of this embodiment is composed of an upper shell 1 and a lower shell 2. The upper shell 1 and the lower shell 2 can be paired and fastened together in a snap-fit manner and locked and fixed by screws. The inner walls of the upper shell 1 and the lower shell 2 are both provided with limiting ribs for pairing and pressing the high-speed brushless motor 16, the sleeve 15, the main control circuit board 18, and the insulation tube 13, ensuring the stability of the installation of the high-speed brushless motor 16, the sleeve 15, the main control circuit board 18, and the insulation tube 13. A filter screen 17 is provided at the end of the high-speed brushless motor 16 near the air inlet 8. The inner side surface of the tail cover 7 is provided with an air inlet screen corresponding to the position of the air inlet 8. The air inlet screen is installed by a bracket 9, which is set on the inner wall of the tail cover 7. The air inlet screen includes a side air inlet screen 10 corresponding to the air inlet 8 on the side of the tail cover 7 and a tail end air inlet screen 11 corresponding to the air inlet 8 on the tail end surface of the tail cover 7. The side air inlet screen 10 has an arc-shaped structure, and the tail end air inlet screen 11 has a circular sheet structure.

The middle part of the housing is the grip portion, as shown in Figures 1 and 2. The diameter of the air inlet end is larger than the diameter of the grip portion, and the diameter of the air inlet end gradually decreases along the direction of the grip portion, so that the inner diameter of the air duct at the end close to the air inlet 8 gradually decreases along the end away from the air inlet 8. The diameter of the air inlet end gradually decreases along the direction of the grip portion, so that the internal air duct of the air inlet end is combined with the internal air duct of the grip portion and the air outlet end to form a structure of a large air inlet cavity that gradually decreases. By increasing the diameter of the air inlet end, the air intake volume is significantly increased, forming a higher wind pressure, and at the same time, the air intake volume of the high-speed brushless motor 16 is increased, so that it can reach the optimal working state. Compared with the products of the prior art that use high-speed brushless motors 16 of the same power, the structure of the utility model that increases the internal cavity of the air outlet end can improve the wind speed and output power of the product as a whole. At the same time, due to the increase in the air intake volume, the resistance of the air duct can be reduced, making the wind flow in the air duct smoother, thereby achieving the technical effect of reducing noise.

The test data of the supercharged high-speed hot air blower of this embodiment is compared with the prior art. The specific test data comparison results are shown in the following table:

As shown in the table above, both comparison products use a high-speed brushless motor 16 of equal power, and are subjected to wind speed tests, power tests, decibel tests, temperature tests, and wind pressure tests. Compared with the prior art, the boosted high-speed hot air blower of the embodiment has improvements in wind speed, power, noise reduction, temperature, and wind pressure.
