Description

Technical Field

[0001] This utility model relates to the field of hair dryer equipment technology, specifically a high-speed hair dryer that prevents airflow from escaping. Background Technology

[0002] A hair dryer is mainly composed of a set of heating wires and a high-speed small fan. The hair dryer is mainly used to dry hair. When it is powered on, the heating wires generate heat, and the air blown out by the fan passes through the heating wires to output hot air.

[0003] Some existing high-speed hair dryers have designs to prevent airflow leakage, but the display components are placed or enclosed at the rear end of the high-speed hair dryer body opposite the air outlet. This design means that the high-speed hair dryer can only rely on the end of the handle to take in air, which limits the amount of air intake. As a result, the air output efficiency relies entirely on increasing the motor speed, which consumes a lot of energy.

[0004] For example, the aforementioned problem exists in patent (CN219781821U); it describes "a high-speed hair dryer, including a hollow body and a handle, the body and the handle are connected, the handle has a second air duct, the body has a first air duct, the first air duct and the second air duct are intersecting and connected, the handle has an air inlet at the end away from the body, the handle has a fan assembly; the front end of the body has an air outlet, the body has a guide component for guiding airflow to the air outlet at the connection of the first air duct and the second air duct, the body has a heating component for heating the airflow and a heat insulation component for fixing the heating component in the body." The high-speed hair dryer in the above patent has a design to prevent airflow leakage, but its design mainly guides the airflow to reduce airflow leakage. However, the high-speed hair dryer body has a display component arranged at the rear end opposite to the air outlet. This design means that the high-speed hair dryer can only rely on the end of the handle for air intake, which limits the air intake volume. As a result, the air output efficiency relies entirely on increasing the motor speed, resulting in high energy consumption.

[0005] To address the issue that the high-speed hair dryer has a display component or is enclosed at the rear end opposite the air outlet, which limits the air intake and causes the air output efficiency to rely entirely on increasing the motor speed, resulting in high energy consumption, we propose a high-speed hair dryer that prevents airflow leakage. Utility Model Content

[0006] The purpose of this invention is to provide a high-speed hair dryer that prevents airflow from escaping, so as to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-speed hair dryer for preventing airflow leakage, comprising a main body and a handle, wherein the handle is vertically disposed at the bottom of the main body, and the top of the handle is connected to the bottom of the main body; an auxiliary air inlet plate, an auxiliary air inlet frame, and an auxiliary air inlet cover are provided on the side of the main body away from the air outlet; the auxiliary air inlet frame is disposed between the auxiliary air inlet plate and the auxiliary air inlet cover; the auxiliary air inlet plate is disposed between the air outlet and the auxiliary air inlet frame; a first fan blade is rotatably connected between the auxiliary air inlet plate and the air outlet inside the main body; and an air guide nozzle is provided between the main body and the handle, with the top of the air guide nozzle facing the first fan blade.

[0008] Furthermore, the auxiliary air intake plate has a disc-shaped structure, and a ventilation opening is provided at the bottom of the outer wall of the auxiliary air intake plate.

[0009] Furthermore, the auxiliary air intake frame includes a first air intake plate and a second air intake plate, the first air intake plate being disposed between the auxiliary air intake plate and the second air intake plate, and the outer diameter of the second air intake plate being smaller than the outer diameter of the first air intake plate.

[0010] Furthermore, the outer wall of the second air inlet plate is provided with a trumpet-shaped first air inlet on the center of the side near the first air inlet plate, and the outer wall of the first air inlet plate is provided with a second air inlet outside the first air inlet.

[0011] Furthermore, the outer wall of the auxiliary air inlet hood is provided with a plurality of first auxiliary air inlet holes at its center, and the outer wall of the auxiliary air inlet hood is provided with a plurality of second auxiliary air inlet holes on its periphery, the second auxiliary air inlet holes being located between the second air inlet plate and the first air inlet plate.

[0012] Furthermore, a support frame is provided inside the main body on the outside of the first fan blade, and an electric heating wire is provided on the inner wall of the support frame on the outside of the first fan blade.

[0013] Furthermore, a cross-shaped bracket is provided on the outer wall of the support frame near the air outlet. One end of the first fan blade is rotatably connected to the center of the outer wall of the auxiliary air inlet plate, and the other end of the first fan blade is rotatably connected to the cross-shaped bracket.

[0014] Furthermore, a motor is provided inside the grip below the air guide nozzle, and a second fan blade is driven to the output end of the motor. An air inlet is provided on the outer wall of the grip below the motor.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0016] 1. This utility model provides airflow to the main body through the setting of an auxiliary air inlet plate, an auxiliary air inlet frame, an auxiliary air inlet cover, a first fan blade, and an air guide nozzle. The airflow is delivered into the main body through the air guide nozzle, and the airflow delivered in the air guide nozzle directly impacts the first fan blade. The first fan blade rotates, and then the airflow is ejected from the air outlet in a vortex state under the drive of the rotation of the first fan blade, realizing the blowing operation of the hair dryer. The airflow driven by the rotation of the first fan blade makes the airflow of the hair dryer greater and the air output efficiency higher. The top of the air guide nozzle is designed to face the first fan blade, so that the airflow delivered in the air guide nozzle directly... The airflow impacts the first fan blade, preventing it from escaping to the side of the main body furthest from the air outlet. The auxiliary air inlet plate, auxiliary air inlet frame, and auxiliary air inlet hood provide auxiliary air intake at the side of the main body furthest from the air outlet, supplementing the air intake volume of the high-speed blower. With the same motor speed, the high-speed blower has a larger air intake volume, effectively reducing energy consumption. The first fan blade can deliver airflow from the side of the main body furthest from the air outlet to the air outlet, ensuring that the auxiliary air inlet plate, auxiliary air inlet frame, and auxiliary air inlet hood only allow air to enter but not exit, thus increasing the air intake volume while preventing airflow from escaping.

[0017] 2. In this utility model, by setting an auxiliary air inlet plate, a first air inlet plate and a second air inlet plate, a first auxiliary air inlet hole and a second auxiliary air inlet hole, and designing the ventilation opening at the bottom of the auxiliary air inlet plate, the airflow entering the main body from the ventilation opening moves in the same direction as the airflow ejected from the air guide nozzle, ensuring that the first fan blade rotates in one direction; the auxiliary air inlet frame is designed as a double-layer structure of the first air inlet plate and the second air inlet plate, and the airflow moves along the shape of the first air inlet plate and the second air inlet plate, which can effectively guide the air inlet; by designing the auxiliary air inlet channel, the difficulty of airflow escaping from this point can be effectively increased, thereby preventing airflow from escaping.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figures 1-4 This utility model provides a technical solution: a high-speed hair dryer for preventing airflow leakage, comprising a main body 1 and a handle 2. The handle 2 is vertically disposed at the bottom of the main body 1, and the top of the handle 2 is connected to the bottom of the main body 1. An auxiliary air inlet plate 3, an auxiliary air inlet frame 4, and an auxiliary air inlet cover 5 are provided inside the main body 1 on the side away from the air outlet 6. The auxiliary air inlet frame 4 is disposed between the auxiliary air inlet plate 3 and the auxiliary air inlet cover 5. The auxiliary air inlet plate 3 is disposed between the air outlet 6 and the auxiliary air inlet frame 4. The auxiliary air inlet plate 3 is disposed between the air outlet 6 and the auxiliary air inlet frame 4. A first fan blade 7 is rotatably connected between the air outlets 6 and the main body 1 and the handle 2. An air guide nozzle 8 is provided between the main body 1 and the handle 2, with the top of the air guide nozzle 8 facing the first fan blade 7. A support frame 101 is provided inside the main body 1 outside the first fan blade 7, and an electric heating wire 102 is provided on the inner wall of the support frame 101 outside the first fan blade 7. A motor 201 is provided inside the handle 2 below the air guide nozzle 8. The output end of the motor 201 is connected to a second fan blade 202. An air inlet 203 is provided on the outer wall of the handle 2 below the motor 201.

[0027] In one embodiment, a cross-shaped bracket 103 is provided on the outer wall of the support frame 101 near the air outlet 6. One end of the first fan blade 7 is rotatably connected to the center of the outer wall of the auxiliary air inlet plate 3, and the other end of the first fan blade 7 is rotatably connected to the cross-shaped bracket 103. The cross-shaped bracket 103 and the auxiliary air inlet plate 3 provide rotational support at both ends of the first fan blade 7, which can effectively ensure the safety and stability of the first fan blade 7 during rotation.

[0028] The working principle of this utility model:

[0029] Refer to the instruction manual appendix Figures 1-4 This utility model, through the arrangement of an auxiliary air inlet plate 3, an auxiliary air inlet frame 4, an auxiliary air inlet cover 5, a first fan blade 7, and an air guide nozzle 8, provides an air outlet channel for the main body 1 within the hair dryer. The handle 2 serves as both the handheld part and the air supply channel, providing airflow to the main body 1. The airflow is delivered into the main body 1 through the air guide nozzle 8. The airflow delivered through the air guide nozzle 8 directly impacts the first fan blade 7, causing it to rotate. Driven by the rotation of the first fan blade 7, the airflow is then ejected from the air outlet 6 in a vortex state, thus enabling the hair dryer to blow air. The airflow driven by the rotation of the first fan blade 7 results in a higher air velocity and higher airflow efficiency. The top of the air guide nozzle 8 is designed to face the first fan blade 7, ensuring that the airflow delivered through the air guide nozzle 8 directly impacts the first fan blade 7, preventing airflow from entering the main body 1. The air escapes from the end away from the air outlet 6; at the same time, an auxiliary air inlet plate 3, an auxiliary air inlet frame 4, and an auxiliary air inlet cover 5 are arranged inside the main body 1 at the end away from the air outlet 6, so that the auxiliary air inlet plate 3, the auxiliary air inlet frame 4, and the auxiliary air inlet cover 5 provide auxiliary air intake at the end of the main body 1 away from the air outlet 6, which can supplement the air intake volume of the high-speed blower. Under the same motor speed, the high-speed blower has a larger air intake volume, which can effectively reduce energy consumption; by designing the shape of the surface of the first fan blade 7, the first fan blade 7 can transport the air volume from the air guide nozzle 8 to the air outlet 6, thereby realizing that the first fan blade 7 transports the air volume from the end of the main body 1 away from the air outlet 6 to the air outlet 6. This also ensures that the auxiliary air inlet plate 3, the auxiliary air inlet frame 4, and the auxiliary air inlet cover 5 only take in air and do not let out air, thereby ensuring that the air volume is increased while preventing the airflow from escaping;

[0030] The support frame 101 supports the electric heating wire 102. When the airflow moves from the first fan blade 7, it comes into contact with the electric heating wire 102 to heat the airflow and output hot air. The motor 201 inside the handle 2 drives the second fan blade 202 to rotate. The second fan blade 202 delivers outside air from the air inlet 203 into the handle 2, and then the air is delivered from the air guide nozzle 8 into the first fan blade 7 inside the main body 1.

[0031] Example 2

[0032] Please see Figures 2-4 This utility model provides a technical solution: a high-speed blower for preventing airflow leakage, wherein the auxiliary air inlet plate 3 is a disc-shaped structure, and a ventilation opening 301 is provided at the bottom of the outer wall of the auxiliary air inlet plate 3; the auxiliary air inlet frame 4 includes a first air inlet plate 401 and a second air inlet plate 402, the first air inlet plate 401 is disposed between the auxiliary air inlet plate 3 and the second air inlet plate 402, and the outer diameter of the second air inlet plate 402 is smaller than the outer diameter of the first air inlet plate 401; a trumpet-shaped first air outlet 403 is provided at the center of the outer wall of the second air inlet plate 402 near the first air inlet plate 401, and a second air outlet 404 is provided on the outer wall of the first air inlet plate 401 outside the first air outlet 403; a plurality of first auxiliary air inlet holes 501 are provided at the center of the outer wall of the auxiliary air inlet cover 5, and a plurality of second auxiliary air inlet holes 502 are provided on the outer periphery of the outer wall of the auxiliary air inlet cover 5, and the second auxiliary air inlet holes 502 are located between the second air inlet plate 402 and the first air inlet plate 401.

[0033] The working principle of this utility model:

[0034] Refer to the instruction manual appendix Figures 2-4 This utility model, by setting an auxiliary air inlet plate 3, a first air inlet disc 401 and a second air inlet disc 402, a first auxiliary air inlet hole 501 and a second auxiliary air inlet hole 502, designs the auxiliary air inlet plate 3 into a disc-shaped structure to ensure that the auxiliary air inlet plate 3 provides disc-shaped isolation and support for the airflow inside the main body 1. The vent 301 provides an air inlet on the auxiliary air inlet plate 3. The vent 301 is designed at the bottom of the auxiliary air inlet plate 3 so that the airflow entering the main body 1 from the vent 301 moves in the same direction as the airflow ejected from the air guide nozzle 8, ensuring that the first fan blade 7 rotates in one direction. The auxiliary air inlet frame 4 is designed as a double-layer structure of the first air inlet disc 401 and the second air inlet disc 402, and a first air inlet 403 and a second air inlet 404 are designed at the contact position of the first air inlet disc 401 and the second air inlet disc 402, so that when the airflow enters the auxiliary air inlet frame 4, the airflow follows the first air inlet. The design of the plate 401 and the second air intake plate 402 allows for effective airflow guidance. When outside air enters through the auxiliary air intake hood 5, it enters the outside of the auxiliary air intake frame 4 through the first auxiliary air intake hole 501. This air then directly enters through the first air outlet 403 of the second air intake plate 402 and passes through the auxiliary air intake frame 4. Outside air also enters the outside of the auxiliary air intake frame 4 through the second auxiliary air intake hole 502. This air then directly enters between the first air intake plate 401 and the second air intake plate 402. The airflow then moves out through the gap between the first air outlet 403 and the second air outlet 404, and then enters through the first air outlet 403 and passes through the auxiliary air intake frame 4. The airflow then passes through the ventilation opening 301 of the auxiliary air intake plate 3 and enters the interior of the main body 1 to supplement the air intake volume. By guiding the auxiliary air intake channel, the difficulty of airflow escaping from this point can be effectively increased, thereby preventing airflow escaping.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
