Description

Technical Field

[0001] This utility model relates to the field of hair dryer technology, and in particular to a nozzle that swings back and forth with the wind. Background Technology

[0002] Hair dryers are widely used in daily household use and the hairdressing industry. In traditional hair dryers, the size of the air outlet is often a constant value. To increase the variety of blowing effects, hair dryers are often equipped with nozzles to disperse or concentrate the airflow.

[0003] As shown in Figure 1, a commonly used diffuser nozzle is characterized by its large size and multiple densely packed small air outlets. Therefore, it has the advantages of a large air outlet area and uniform heat dissipation, making it suitable for close-range hair drying. However, due to the large number of air outlets, the air pressure and air speed are reduced, and the airflow path is shortened, making it unsuitable for long-distance hair drying.

[0004] As shown in Figure 2, the commonly used concentrating flat nozzle is characterized by its small size and narrow, converging air outlet, which increases air pressure and speed, and concentrates heat, making it suitable for long-distance hair drying. However, when the heat is concentrated on the scalp for a short time, the scalp will feel overheated and scalded. Therefore, it is necessary to constantly swing the hair dryer back and forth with your hand, which will cause wrist fatigue. Whether you are using it yourself or someone else is helping you dry your hair, it is easy to burn your scalp and damage your hair if you are not careful, causing inconvenience in use. Utility Model Content

[0005] To solve the above problems, this utility model provides a nozzle that swings back and forth with the wind, automatically and continuously switching the direction of the wind during the blowing process. While achieving high wind speed and high wind pressure, it effectively avoids scalding the scalp due to heat accumulation, effectively protects the hair quality, and is easy to use.

[0006] To achieve the above objectives, one of the technical solutions adopted by this utility model is: a nozzle that swings back and forth with the wind, comprising a nozzle body and a deflector. The nozzle body is hollow inside to form an air duct. Both ends of the air duct are connected to an air outlet and an air inlet that communicates with the air outlet of a blower. The deflector is a rigid body with a symmetrical structure and includes a swing head and a hinge. The deflector is hinged to the air duct inside the nozzle body or at the air outlet. Airflow flows in from the air inlet and flows to the swing head. The stable balance state of the deflector is repeatedly disturbed by the airflow, thus causing it to swing back and forth.

[0007] Preferably, the air outlet of the nozzle body is a narrow, elongated, flat air outlet, and the deflector is fixedly hinged or detachably hinged to the air outlet of the nozzle body.

[0008] Preferably, the nozzle body is integrally formed to form an air inlet section, a constriction section and an air outlet section, the air outlet section is formed with an air guide shroud, and the deflector is disposed inside the air guide shroud.

[0009] Preferably, a connecting piece is provided between the swing head and the hinge.

[0010] Preferably, the oscillating head includes a symmetrically distributed first windward surface and a second windward surface, and a symmetrically distributed first windward surface and a second windward surface. An angle is formed between the first windward surface and the second windward surface, and an angle is formed between the first windward surface and the second windward surface. The first windward surface, the second windward surface, the second windward surface, and the first windward surface are sequentially arranged to form a rhombus structure.

[0011] Preferably, two symmetrically inclined strip plates are connected to both sides of the connecting piece. The two strip plates facing the air inlet are far apart from each other, while the two strip plates facing away from the air inlet are close to each other.

[0012] Preferably, the connecting piece and the two shaped plates form two symmetrical air vents.

[0013] Preferably, the connecting piece is provided with a hollowed-out portion, and the air vent of the central axis of the ornament is formed between the two plates.

[0014] Preferably, the deflector is fixedly connected to a separately molded air guide cover, which is detachably connected to the air inlet of the nozzle body.

[0015] Preferably, the air guide shroud has a fan-shaped air outlet arc edge.

[0016] Preferably, the deflector generates at least one air knife at each swing angle during its reciprocating oscillation.

[0017] The beneficial effects of this utility model are as follows: by setting a symmetrical unstable balance structure, the oscillating component can be rotatably connected inside the receiving cavity or directly rotatably connected outside the air outlet. Under the action of wind force, the oscillating component makes a reciprocating swinging motion. Without changing the wind speed and wind pressure, the direction of the wind can be automatically and continuously switched during the blowing process. This simulates the manual swinging of the hair dryer during the blowing process to achieve reciprocating sweeping of high temperature and strong wind in the left-right or up-down direction, improving the convenience of use, effectively avoiding scalding of the scalp due to heat accumulation, and effectively protecting the hair quality.

[0046] The present invention will now be described in further detail with reference to the accompanying drawings.

[0047] Example 1

[0048] Please refer to Figures 3-5. This embodiment discloses a nozzle that swings back and forth with the wind, including a nozzle body 1, an air guide 2, and a deflector 3. The nozzle body 1 and the air guide 2 are integrally formed into a nozzle. The nozzle has a hollow interior with an air duct, as shown in Figure 7. The air duct includes an inlet section 15, a contraction section 16, and an outlet section 17 connected in sequence. The cross-sectional area of ​​the inlet section 15 is larger than that of the contraction section 16. That is, looking along the longitudinal direction of the nozzle, from the air inlet 11 to the contraction section 16, the cross-sectional area of ​​the air duct inside the nozzle gradually decreases to form an air duct with a gradually narrowing width. The air duct with a gradually narrowing width is set close to the outlet section 17. The air pressure and air speed are increased by the contraction section 16, thereby making the hair dryer more efficient. The air guide 2 is located in the outlet section 17. The air guide 2 has a fan-shaped air outlet arc edge 21. The deflector 3 is rotatably connected inside the air guide 2 and swings back and forth along the fan-shaped arc direction.

[0049] Specifically, as shown in Figure 5, the high-temperature strong wind mode of reciprocating up and down direction sweeps hot air along the deflector 3 to form an air knife 18. The air knife 18 always maintains high speed and carries high heat output. The air knife 18 swings down from several angles cdefg and then swings up from several angles gfedc, repeating the cycle. At least one air knife 18 is output in each swing angle state. The air knife 18 in each state sweeps quickly, which not only ensures the output of high-speed high-temperature hot air, but also avoids the risk of skin burns due to excessive local heating time.

[0050] Specifically, as shown in Figure 6, the high-temperature strong wind mode is swept back and forth in the left and right direction. Hot air is swept along the deflector 3 to form a wind knife 18. The wind knife 18 always maintains high speed and carries high heat output. The wind knife 18 swings to the right from several angles from mkjih, and then swings to the left from several angles from hijkm, and repeats itself.

[0051] In this embodiment, the inner wall of the air inlet 11 of the nozzle body 1 is provided with a plurality of inner connectors 13, and the outer wall of the air inlet 11 is provided with a plurality of outer snap-fit ​​grooves 14. The nozzle body 1 is detachably connected to the hair dryer (not shown in the figure) through the inner connectors 13 and the outer snap-fit ​​grooves 14.

[0052] Please refer to Figure 5-7. When the hair dryer is working, the airflow enters from the air inlet 11, passes through the constriction section 16 to increase the airflow pressure and speed, and gathers heat. Then, the high-pressure, high-speed, and high-heat airflow enters the air guide shroud 2, causing the deflector 3 to swing back and forth along the fan-shaped arc direction under the action of the wind. This realizes the automatic and continuous switching of the airflow direction during the blow-drying process, simulating the manual swinging of the hair dryer during the blow-drying process, improving the practicality and convenience, effectively avoiding scalding of the scalp due to heat accumulation, and effectively protecting the hair quality.

[0053] Please refer to Figures 5-8. The oscillating component 3 includes an oscillating head 31, a connecting piece 32, and a hinge 33. The oscillating head 31 and the hinge 33 are respectively disposed at both ends of the connecting piece 32. The oscillating component 3 is rotatably connected to the receiving cavity through the hinge 33. Preferably, in this embodiment, the oscillating head 31 includes a symmetrically distributed first windward surface 311 and a second windward surface 312, and a symmetrically distributed first airflow guiding surface 313 and a second airflow guiding surface 314. An angle is formed between the first windward surface 311 and the second windward surface 312, and an angle is formed between the first airflow guiding surface 313 and the second airflow guiding surface 314. The first windward surface 311, the second windward surface 312, the second airflow guiding surface 314, and the first airflow guiding surface 313 sequentially form a hollow closed rhomboid structure. In this embodiment, the hinge 33 is a rotating shaft sleeve. The two side walls of the contraction section 16 near the air guide shroud 2 are provided with shaft holes 22. The rotating shaft (not shown in the figure) is inserted into the shaft hole 22 and the hinge 33 in sequence, so that the oscillating member 3 is rotatably connected to the air guide shroud 2. The two ends of the rotating shaft are respectively fixed on the shaft hole 22 to realize the rotatable connection of the oscillating member 3. The connecting piece 32 controls the swing amplitude of the oscillating member 3. Specifically, the longer the connecting piece 32 is, the larger the swing amplitude, and the shorter the connecting piece 32 is, the smaller the swing amplitude. In this embodiment, the connecting piece 32 can be omitted. Preferably, the first windward surface 311 and the first air guide surface 313 are transitioned by a curved section arc 315. The second windward surface 312 and the second air guide surface 314 are transitioned by a curved section arc 315. The first windward surface 311, the second windward surface 312, the second air guide surface 314, and the first air guide surface 313 are all flat or smooth surfaces, which makes the swing effect better. It should be noted that "rotatable connection" is widely known to those skilled in the art, and this embodiment is merely one implementation method and is not intended to limit the technical solution.

[0054] Please refer to Figures 9-10. As a first modified structure of the oscillating component 3, the oscillating head 31 of the oscillating component 3 includes two symmetrically arranged strip plates 316. The two strip plates 316 are respectively fixed to the two side surfaces of the end of the connecting piece 32 and are inclined to the connecting piece 32. The two strip plates 316 are far apart from each other on the side facing the air inlet 11, and close together on the side facing away from the air inlet 11. The strip plates 316 and the connecting piece 32 form symmetrical air inlets 317 for the oscillating component. The two symmetrical air inlets 317 can simultaneously spray airflow to form two air blades 18. In this modified embodiment, when the oscillating component 3 oscillates, each In any state, at least two air blades 18 can be generated simultaneously; please refer to Figures 11-12. As the second deformation structure of the deflector 3, the difference from the first deformation structure is that the two plates 316 are tilted in opposite directions. This deformation embodiment is not effective. The deflector 3 is difficult to start when it swings and is easy to stop on one side; please refer to Figure 13. As the third deformation structure of the deflector 3, the difference from the first deformation structure is that the ends of the two plates 316 are connected so that the two plates 316 form an integral structure. The symmetrical air vent 317 formed by the strip plate 316 and the connecting piece 32 is a closed loop.

[0055] Please refer to Figure 14. As the fourth variant of the oscillating component 3, it differs from the third variant in that a hollow portion 321 is provided in the middle of the connecting piece 32, and a central air vent 318 is formed between the two strip plates 316. The air jet from the central air vent 318 forms only one air knife 18. In this variant embodiment, when the oscillating component 3 oscillates, at least one air knife 18 can be generated in each state. Please refer to Figures 15-16. As the fifth variant of the oscillating component 3, it differs from the oscillating component 3 in that a hollow portion 321 is provided in the middle of the connecting piece 32. By providing the hollow portion 321, the weight of the connecting piece 32 can be reduced, and the oscillation efficiency can be improved.

[0056] Example 2

[0057] Please refer to Figure 17. This embodiment discloses a reciprocating air nozzle, including a nozzle body 1 and a deflector 3. One end of the nozzle body 1 is an air inlet 11 for detachable connection with a hair dryer, and the other end is a tapered, elongated, flat air outlet 12. The flat air outlet 12 corresponds to the constriction section 16 in Embodiment 1. Compared to Embodiment 1, the air guide cover 2 is omitted. The nozzle body 1 is a conventional flat nozzle structure. The deflector 3 is rotatably connected to the elongated, flat air outlet 12. Under the action of wind, the deflector 3 reciprocates outside the elongated, flat air outlet 12. The deflector 3 is detachably installed on the flat nozzle, meaning that the flat nozzle does not need to be remolded; only the deflector needs to be remolded. Thus, by adding a deflector to the existing flat nozzle base, the risk of scalding the scalp due to heat accumulation can be effectively avoided.

[0058] The difference between this embodiment and embodiment one is that the air outlet of the nozzle body 1 is a gradually narrow strip-shaped flat air outlet 12, and the air guide shroud 2 is omitted. The deflector 3 is rotatably connected to the narrow strip-shaped flat air outlet 12, so that the swing amplitude of the deflector 3 is not restricted by the air guide shroud 2, thus increasing the swing range.

[0059] In this embodiment, pins 121 are provided on both sides of the narrow strip-shaped air outlet 12. The deflector 3 is only provided with a swing head 31 and a hinge 33. The hinge 33 is a closed retaining ring 331 corresponding to the pin 121. The deflector 3 is engaged with the pin 121 by the closed retaining ring 331. As shown in Figure 18, as a variation, the hinge 33 is a semi-closed retaining ring 332. Compared with the closed retaining ring 331, the semi-closed retaining ring 332 is easier to disassemble and install.

[0060] Please refer to Figure 19. As a variation, the narrow strip-shaped air outlet 12 is provided with pivot seats 122 on both sides. The pivot seats 122 are provided with shaft holes. The two ends of the swing head 31 in the oscillating component 3 are provided with pins 121 and connected to the shaft holes.

[0061] It should be noted that in this embodiment, the oscillating member 3 is only provided with a swing head 31 and a hinge member 33. Of course, as in embodiment one, a connecting piece 32 can be added between the swing head 31 and the hinge member 33 to adjust the swing amplitude of the oscillating member.

[0062] Example 3

[0063] Please refer to Figure 20. The difference between this embodiment and Embodiment 1 is that the air guide shroud 2 is detachably connected to the air inlet 11 of the nozzle body 1. Compared to Embodiment 1, where the nozzle body 1 and the air guide shroud 2 are integrally formed, this embodiment allows for the replacement of air guide shrouds 2 of different sizes to adapt to different usage scenarios. It should be noted that "detachable connection" is widely known to those skilled in the art and will not be elaborated upon here.

[0064] Example 4

[0065] Please refer to Figures 21-22. The difference between this embodiment and Embodiment 1 is that the air duct does not have a contraction section 16. The cross-sectional area of ​​the air duct inside the nozzle gradually increases to form an air duct with a gradually widening width. The number of deflecting components 3 is one or more. By increasing the number of deflecting components 3, the air force can be blown out in multiple directions.

[0066] During the research process, the applicant conducted multiple experiments on the materials and structure of the oscillating component. The following is a detailed analysis of the oscillation of oscillating component 3:

[0067] Figure 23 shows a schematic diagram of the unstable equilibrium force analysis of the oscillating component 3 in Embodiment 1. Initially, the oscillating component 3 may randomly stop at one of states a, b, or c. With just a slight tilt of the product or the application of an external force, the oscillating component 3 will lose its equilibrium. In state a, under the influence of airflow, a resultant oscillating force F is generated pointing towards state c. a In state c, under the influence of airflow, a resultant yaw force F is generated pointing in the direction of state a. c State b is an extremely unstable state. Generally, a resultant force F will only occur when the airflow is very small and the airflow is subjected to a vertically downward gravitational force. b state.

[0068] Figure 24 illustrates some failed oscillation schemes. From left to right, the three schemes are: left 1, left 2, left 3, left 4, and left 5. Left 1 and left 2 use flat rigid sheets, left 3 uses a bent rigid sheet with misaligned left and right sides, left 4 uses a combination structure of "flat rigid sheet + flexible sheet", and left 5 uses a flexible sheet alone. All of the above schemes have difficulty starting in the experiment and cannot achieve the expected oscillation effect.

[0069] As shown in Figure 25, the order from left to right is left 1, left 2, left 3, and left 4. Left 1 and left 2 are double flexible sheets with a forked design. The swaying frequency is too high, which can easily produce a buzzing and piercing noise. Left 3 and left 4 are single flexible sheets with asymmetrical protruding guide surfaces. They also have the problem of excessively high swaying frequency and buzzing and piercing noise. In addition, the swaying will tilt to one side, and the overall swaying effect is not good.

[0070] As shown in Figure 26, a flexible sheet is used to connect the two rigid sheets. Although no buzzing noise is generated, there is still obvious noise, which causes auditory discomfort during use. Experimental verification shows that the swaying effect and user experience of Examples 1, 2 and 3 are better.

[0071] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. 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.
