Description

Technical Field

[0001] The utility model relates to the technical field of hair dryer accessories, in particular to an easily detachable air outlet accessory for a hair dryer. Background Art

[0002] Heated hair styling appliances are designed to use the action of heat, mechanical devices and / or airflow to form hair into a desired shape or style.

[0003] Hair dryers are commonly used household appliances, mainly used for drying and shaping hair, and can also be used for local drying, heating and treatment in laboratories, physiotherapy rooms, industrial production, art, etc., and are widely used. In particular, hot hair dryers are used for a variety of purposes, such as drying materials (such as paint and hair), and cleaning or stripping surface layers.

[0004] At present, the hair dryers commonly seen on the market are mostly used for drying and assisting hair styling. Widely used hair dryers are equipped with an air outlet attachment in various shapes. For example, a heat drying hood (commonly known as a diffuser) is used to dry curly hair when using a hair dryer to dry hair, so that the curly hair is not easily messy and can maintain the original curly hair shape after drying the hair. The diffuser guides the air flow, so that the hair dryer has a better air outlet effect.

[0005] Prior art example 1, referring to patent document CN219578435U, discloses a hair care accessory and a hair care device assembly, wherein the hair care accessory has an air outlet slot, a first docking end and a second docking end, and the hair care accessory is configured such that when the first docking end takes in air, the air outlet slot exhausts air in a clockwise direction, and when the second docking end takes in air, the air outlet slot exhausts air in a counterclockwise direction. According to the hair care accessory in the embodiment of the utility model, the hair care accessory can be changed in the direction of curling without changing the operation direction, by changing the docking position of the hair care accessory, so as to meet the needs of curling hair in different directions and improve the user experience. Example 1 has some defects during use, for example: 1. Although it has the functions of forward and reverse air outlet, in order to achieve wind direction switching, the hair care accessory needs to be disassembled from the hair dryer and then reassembled in reverse direction. Each reversal requires disassembly and assembly, and the opening and closing of the valve assembly needs to be reversed, which makes the operation more complicated and the chance of damage is higher; 2. The lack of a wind gathering structure results in low wind pressure and slow wind speed; 3. The air duct structure is single and cannot play a good role in guiding the flow; 4. The matching relationship and installation structure between the various components are unknown, and disassembly and assembly cannot be achieved. Summary of the invention

[0055] Embodiment 1

[0056] Reference Figures 1 to 12 , an easily detachable air outlet accessory 5 for a hair dryer, comprising, from back to front:

[0057] The air inlet bracket 1 is used to connect with and connect the hair dryer 6. The rear end of the air inlet bracket 1 has an air inlet port 1a, and the front end has a guide port 1b, which plays the role of guiding, converging and pressurizing;

[0058] The cylindrical air outlet bracket 2 has a rear end which is detachably connected to the guide port 1b of the air inlet bracket 1, and a plurality of air outlet openings 22 are arranged on the outer peripheral wall 21 of the cylindrical air outlet bracket 2;

[0059] A top end cover bracket 3, which is detachably connected to the front end of the cylindrical air outlet bracket 2;

[0060] The control knob 4 is at least partially disposed in the top end cover bracket 3 and forms a transmission match with the cylindrical air outlet bracket 2 to achieve the function of switching the air outlet channel opening 22;

[0061] The cylindrical air outlet bracket 2 includes a cylindrical air outlet base 23, a plurality of air outlet panels 24, and a reversing shaft 25;

[0062] Among them, refer to Figure 4 The cylindrical air outlet base 23 is provided with a plurality of assembly grooves 231, and the air outlet panel 24 is inserted into the assembly grooves 231 to realize the rapid assembly of the air outlet panel 24 and the cylindrical air outlet base 23. To separate the two, it is only necessary to fix the cylindrical air outlet base 23 and then pull the air outlet panel 24 out of the assembly groove 231. In addition, there is a gap between the outer peripheral wall 21 of the cylindrical air outlet base 23 and the air outlet panel 24 to form the air outlet channel opening 22;

[0063] The cylindrical air outlet base 23 has an air duct cavity 232 inside, the air outlet channel opening 22 is connected to the guide port 1b through the air duct cavity 232, and the reversing shaft 25 is arranged in the air duct cavity 232 and forms a transmission connection with the control knob 4.

[0064] The above content is the basic structural scheme of the utility model. The air inlet bracket 1, the cylindrical air outlet bracket 2, the top end cover bracket 3 and the control knob 4 are connected in sequence to form a complete air outlet accessory 5. The front and rear connection structure is simple and easy to disassemble and assemble. Among them, the assembly groove 231 is combined with the air outlet panel 24 to assemble multiple air outlet panels 24 to a single cylindrical air outlet base 23, and multiple air outlet channel openings 22 are directly formed after assembly.

[0065] The flow direction of the air flow is: after the air flow enters from the air inlet port 1a of the air inlet bracket 1, it enters the air duct cavity 232 through the guide port 1b, then enters the corresponding air outlet channel opening 22 from the air duct cavity 232, and finally sprays out from the air outlet channel opening 22 to the outside of the air outlet accessory 5.

[0066] The preferred matching method of the air outlet panel 24 and the cylindrical air outlet base 23 is as follows: Figure 10-11 The cross-section of the assembly groove 231 is in a "convex" shape, so that after the air outlet panel 24 is inserted into the "convex" shaped assembly groove 231, it can form a limited anti-detachment fit with the help of the step structure 2311, so that the air outlet panel 24 is firmly connected to the cylindrical air outlet base 23 and can only be taken out along a specific direction.

[0067] Furthermore, referring to Figure 4-5 A positioning groove 2312 is recessed at the bottom of the assembly groove 231, and the air outlet panel 24 has a panel mounting section 241 and a second arc-shaped umbrella section 242. The lower end of the panel mounting section 241 has a positioning rib 2411. The panel mounting section 241 is inserted into the assembly groove 231, and the positioning rib 2411 is snapped into the positioning groove 2312, which plays a structural positioning role and improves the assembly accuracy, thereby making the connection between the air outlet panel 24 and the cylindrical air outlet base 23 more stable.

[0068] It is worth mentioning that the preferred connection structure of the front and rear ends of the cylindrical air outlet base 23 is as follows: Figure 5 , Figure 8 , Fig. 9 The front end of the cylindrical air outlet base 23 is provided with a first front connection hole 233, and the rear end of the top end cover bracket 3 is provided with a second front connection hole 31. The first front connection hole 233 and the second front connection hole 31 are connected with a first fastener (such as a screw, etc.) to fix the cylindrical air outlet bracket 2 and the top end cover bracket 3;

[0069] A first rear connecting hole 234 is provided at the rear end of the cylindrical air outlet base 23, and a second rear connecting hole 111 is provided at the front end of the air inlet bracket 1. A second fastener (such as a screw, etc.) is connected between the first rear connecting hole 234 and the second rear connecting hole 111 to fix the cylindrical air outlet bracket 2 and the air inlet bracket 1.

[0070] Embodiment 2

[0071] Based on the structure of the first embodiment, the present embodiment provides a specific structure of the air inlet bracket 1, referring to Fig. 9The air inlet bracket 1 includes an air inlet outer cover 11, an air inlet inner cover 12, an air breaking cover 13 and a magnetic ring 14. The air inlet inner cover 12 is formed with an inverted cone-shaped air inlet channel 121, and the air inlet port 1a is connected with the guide port 1b through the air inlet channel 121. It is worth mentioning that the inverted cone-shaped air inlet channel 121 shrinks the air inlet channel 121 from back to front, so that the airflow passing through shrinks and squeezes, forming an airflow with faster flow rate and higher pressure.

[0072] The front end of the air inlet outer cover 11 is provided with the second rear connection hole 111; the air inlet inner cover 12 is detachably connected to the air inlet outer cover 11 through the first buckle structure 15, and the air inlet inner cover 12 can cover the second rear connection hole 111, which makes the shape more beautiful, and makes the air inlet flow channel 121 more regular and not abrupt, and can prevent turbulence in the air inlet flow channel 121, thereby reducing air volume loss and improving air intake efficiency. The wind-breaking cover 13 is detachably connected to the inner wall of the air inlet inner cover 12 through the second buckle structure 16, and the wind-breaking cover 13 is located at the air inlet port 1a to play a role in breaking wind and reducing noise. An annular groove 122 is provided at the rear end of the air inlet inner cover 12, and the magnetic ring 14 is embedded in the annular groove 122. With the help of the suction force of the magnetic ring 14, the air inlet bracket 1 (air outlet accessory 5) can be magnetically adsorbed together with the hair dryer 6 as a whole to achieve operation; when storage is required, the air inlet bracket 1 (air outlet accessory 5) can be separated from the hair dryer 6 by only applying reverse force to overcome the suction force.

[0073] Embodiment 3

[0074] Reference Figure 3 to Figure 11 Based on the structure of any of the aforementioned embodiments, a preferred forming structure of an air outlet channel opening 22 is provided, specifically: the cylindrical air outlet base 23 has a plurality of first arc-shaped umbrella-shaped sections 235, and the first arc-shaped umbrella-shaped sections 235 and the second arc-shaped umbrella-shaped sections 242 are arranged at intervals from each other, so that each second arc-shaped umbrella-shaped section 242 and the two adjacent first arc-shaped umbrella-shaped sections 235 form a clockwise air outlet channel opening 26 and a counterclockwise air outlet channel opening 27.

[0075] It is worth mentioning that if the airflow is discharged from the air outlet channel opening 26 in a clockwise direction, a circular vortex airflow 28 flowing in a clockwise direction can be formed around the air outlet attachment 5; if the airflow is discharged from the air outlet channel opening 27 in a counterclockwise direction, a circular vortex airflow 28 flowing in a counterclockwise direction can be formed around the air outlet attachment 5. Due to the existence of the circular vortex airflow 28, a omnidirectional and non-dead angle negative pressure area 281 can be formed around the air outlet attachment 5, so that when the hair 7 approaches the air outlet attachment 5 from any angle, it can be rolled into the surface of the air outlet attachment 5, preventing the hair 7 from flying and being scattered, so as to provide a more consistent and good hair blowing effect.

[0076] It should be particularly emphasized that if the airflow is discharged from the clockwise air outlet 26 and the counterclockwise air outlet 27 at the same time, the airflows in the two directions will interfere with each other, forming very strong turbulence or turbulence, so it needs to be set to be discharged only from one of the air outlet 22 in one direction when in use. In order to achieve the reversing function, the preferred setting of the reversing shaft 25 is: the reversing shaft 25 has a plurality of blocking blocks 251, and the blocking blocks 251 can block any one of the clockwise air outlet 26 and the counterclockwise air outlet 27. Through the operation of the blocking blocks 251, the airflow can be discharged only from one of the clockwise air outlet 26 and the counterclockwise air outlet 27, so as to ensure that a unidirectional, stable annular vortex airflow 28 is formed around the air outlet attachment 5 at the same time.

[0077] The preferred setting is that a plurality of limiting ribs 2321 are evenly arranged in an annular manner in the air duct cavity 232, and movement gaps 2322 are formed between adjacent limiting ribs 2321, and each movement gap 2322 is correspondingly provided with one of the blocking blocks 251, the clockwise air outlet channel opening 26 and the counterclockwise air outlet channel. The blocking block 251 can move along the movement gap 2322 to block any one of the clockwise air outlet channel opening 26 and the counterclockwise air outlet channel opening 27 to limit the movement range of the blocking block 251, ensuring that the movement of the blocking block 251 will not be offset or derailed, thereby being able to successfully seal the column air outlet channel opening 22.

[0078] It is worth mentioning that the preferred configuration of the internal structure of the air outlet channel opening 22 is that a plurality of diverter ribs 243 are provided on the second arc-shaped umbrella-shaped section 242 of the air outlet panel 24, and the diverter ribs 243 evenly divide the air outlet channel opening 22 into a plurality of air outlet units 2431. Preferably, the spacing between adjacent diverter ribs 243 is the same, so that the sizes of the air outlet units 2431 are the same, so that the air outlet is more uniform.

[0079] The further configuration of the diverter rib 243 is that the diverter rib 243 is integrally formed with the air outlet panel 24, and the inner end of the diverter rib 243 abuts against the adjacent first arc-shaped umbrella-shaped section 235, and both sides of the diverter rib 243 are supported by physical structures (the air outlet panel 24 and the first arc-shaped umbrella-shaped section 235), thereby preventing the occurrence of turbulence caused by shaking when high-speed airflow passes through, so as to maintain sufficient position stability and ensure the stability of the air outlet.

[0080] On the other hand, in order to restrict the movement range of the reversing shaft 25, the guide structure of the reversing shaft 25 is as follows: a guide groove 32 is provided on the top end cover bracket 3, a guide block 252 is convexly provided at the front end of the reversing shaft 25, and the guide block 252 extends into the guide groove 32 and can move along the guide groove 32; at the same time, the control knob 4 has a driving groove 41, and the guide block 252 is at least partially inserted into the driving groove 41. Therefore, when the user holds the control knob 4 and applies a rotational force, the control knob 4 can drive the entire reversing shaft 25 to rotate through the guide block 252, and the guide block 252 can only move within the range of the guide groove 32. Once the rotation limit position is reached, the guide block 252 will abut against the side wall of the guide groove 32 and limit the position to prevent further rotation, thereby achieving an effective guiding effect.

[0081] It is worth noting that other technical solutions of the present invention belong to the prior art and will not be described in detail.

[0082] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the concept of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
