Description

Technical Field

[0001] The utility model relates to an air outlet accessory for a hair dryer and the 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 a common hair styling appliance, 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 substances (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 in styling hair. The widely used hair dryers are equipped with a heat drying hood (commonly known as a diffuser). The purpose is that when the hair dryer is used to dry the hair, the hood can be used to dry the curly hair, making the curly hair less likely to be messy and able to 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] As an example of the prior art, referring to patent document CN117545402A, Dyson Technology Co., Ltd. discloses an attachment for a hair care appliance, the attachment having an air inlet and an air outlet. The attachment has a curved surface adjacent to and downstream of the air outlet, and a rib, the rib being positioned so that the rib interacts with the airflow leaving the air outlet to align the airflow leaving the air outlet. The airflow leaving the air outlet generates a first force that attracts the hair toward the curved surface and a second force that pushes the hair away from the curved surface. The technical example has certain limitations during use, for example: 1. The air outlet direction is single. Although it has two air outlets, due to the action of the guide member, the airflow can only be ejected from a single outlet during use. Therefore, the air outlet area is small, resulting in a small wind-receiving area of ​​the hair and a greatly reduced hair care effect; 2. The usage method is single. Limited by the installation structure, it can only be adapted to a vertical body and cannot be installed on most existing models on the market, so its adaptability is poor; 3. The air outlet is uneven. Specifically, its air guide structure will result in a large air volume close to the body and a small air volume away from the body; 4. The function is too single, and it only has a blowing function. Utility Model Content

[0008] An air inlet body, which has a drainage inlet and a drainage outlet, and the drainage inlet is connected with the drainage outlet through a drainage channel;

[0009] The air outlet body has an air inlet chamber and a plurality of air outlet chambers arranged in sequence in front and back, the air inlet chamber is connected to the drainage outlet, each air outlet chamber has an arc-shaped flow-guiding surface, and an air outlet is formed between adjacent arc-shaped flow-guiding surfaces, and the airflow ejected from the air outlet can be attached to the arc-shaped flow-guiding surface to form an arc-shaped airflow;

[0010] A flow divider portion connected to the air outlet body, wherein the air inlet chamber is connected to each air outlet chamber through the flow divider portion;

[0011] The comb tooth body is arranged on the outer wall of the air outlet body.

[0012] A further configuration of the air outlet chamber is that the air outlet chamber has outlet flow channels, and the sizes of the outlet flow channels are different.

[0013] The preferred configuration of the air outlet chamber is that the air outlet chamber includes an upper chamber, a middle chamber and a lower chamber, and the air outlet passage of the middle chamber is larger than the air outlet passages of the upper chamber and the lower chamber.

[0014] The further configuration of the air outlet chamber is that the flow divider portion is provided with a partition rib, the partition rib divides the flow divider portion into a large cavity and a small cavity, the large cavity is directly connected to the air inlet chamber, and the small cavity is connected to the large cavity through an air guide hole provided on the partition rib;

[0015] The small cavity is arranged side by side with the upper cavity and is in conduction with each other, and the large cavity is arranged side by side with the middle cavity and the lower cavity and is in conduction with each other.

[0016] Preferably, the outlet flow passage of the lower chamber has a closed end surface to form a small-sized outlet flow passage of the lower chamber;

[0017] The air inlet body at least partially intrudes into the outlet air passage of the upper chamber, and the upper chamber has an assembly section matched with the air inlet body to form a small-sized outlet air passage of the upper chamber.

[0018] The preferred configuration of the comb tooth body is that the comb tooth body includes a support block and a plurality of comb teeth fixed on the support block, a hollow groove is provided on the air outlet body, the support block is detachably connected in the hollow groove, and the support block and the hollow groove form a clearance fit.

[0019] A preferred configuration of the air outlet is that the air outlet gradually narrows from the back to the front.

[0020] The utility model further comprises a closed body, wherein the flow divider is mounted on one side of the air outlet body, and the closed body is mounted on the other side of the air outlet body.

[0021] In a preferred embodiment of the utility model, the air outlet body is cylindrical, the maximum distance between the air outlet and the center point of the air outlet body is R1, the maximum distance between the arc guide surface and the center point of the air outlet body is R2, and R2≥R1.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] Embodiment 1

[0049] Reference Figures 1 to 13 , an air outlet attachment 11 for a hair styling appliance 8, comprising:

[0050] The air inlet body 2 has a flow inlet 21 and a flow outlet 22, and the flow inlet 21 is connected to the flow outlet 22 through a flow channel 23. Preferably, the flow inlet 21 is equipped with a wind-breaking component 211 to guide the incoming air and achieve a noise reduction effect;

[0051] The air outlet body 3 has an air inlet chamber 31 and a plurality of air outlet chambers 36 arranged in sequence in front and back, wherein the air inlet chamber 31 is connected to the guide outlet 22, and each air outlet chamber 36 has an arc-shaped guide surface 32, and an air outlet 33 is formed between adjacent arc-shaped guide surfaces 32, and the airflow ejected from the air outlet 33 can be attached to the arc-shaped guide surface 32 to form an arc-shaped airflow 34;

[0052] The flow divider portion 4 is connected to the air outlet body 3, and the air inlet chamber 31 is connected to each air outlet chamber 36 through the flow divider portion 4;

[0053] The comb-tooth body 5 is arranged on the outer wall of the air outlet body 3 .

[0054] The above content is the basic structural scheme of the utility model. The air inlet body 2 is connected and connected with the air outlet end of the hair styling device 8 (such as a hair dryer 7) to realize the assembly of the air outlet attachment 11. Figures 4 to 6 During use, the air first enters the drainage channel 23 through the drainage inlet 21 of the air inlet body 2, and flows into a separate air inlet chamber 31 of the air outlet body 3 through the drainage outlet 22, and then the airflow enters the flow diverter part 4 from the air inlet chamber 31, and then the air is diverted by the flow diverter part 4 so that the air flows back to each air outlet chamber 36 of the flow diverter part 4, and the airflow in each chamber is discharged to the outside of the air outlet body 3 along their respective air outlets 33.

[0055] It should be noted that, due to the use of the arc-shaped guide surface 32, the air discharged from the air outlet 33 is effectively guided, so that the discharged air can adhere to the arc-shaped guide surface 32 to form an arc-shaped airflow 34, thereby preventing the air from diffusing and generating turbulence. Figure 4 , Fig.10 When there is an arc-shaped airflow 34, it can drive the nearby airflow to accelerate and form a small-scale negative pressure effect (also known as the Coanda effect). Once the hair 8 is close to the arc-shaped guide surface 32, the hair 8 will be attracted to the arc-shaped guide surface 32 under the action of the negative pressure effect to prevent the hair 8 from floating away. Then, the arc-shaped airflow 34 ejected from the air outlet 33 can be blown onto the hair 8 more directly, achieving a better hair drying and hair care effect.

[0056] At the same time, the arrangement of the comb body 5 can, firstly, comb the hair 8; secondly, contact the scalp to massage and relax the hair; thirdly, limit the hair 8 to prevent the hair 8 from being inflated by wind and flying around; fourthly, create certain gaps between the hair 8 and the skin, and between the hair 8 and the hair 8, so that air can better enter therein, thereby forming better contact between the air and the hair 8, achieving good hair drying and hair care effects.

[0057] Preferably, refer to Figure 8 The air outlet body 3 is cylindrical, the maximum distance between the air outlet 33 and the center point of the air outlet body 3 is R1, the maximum distance between the arc-shaped flow-guiding surface 32 and the center point of the air outlet body 3 is R2, and R2 ≥ R1. The effect achieved is that the arc-shaped flow-guiding surface 32 at least partially protrudes from the flow path of the arc-shaped airflow 34, so that the arc-shaped airflow 34 can better adhere to the arc-shaped flow-guiding surface 32 and can continuously move along the arc-shaped flow-guiding surface 32.

[0058] Reference Figure 1 to Figure 3 , Fig. 9 In the present invention, a closed body 6 is also included. The flow divider 4 is mounted on one side of the air outlet body 3, and the closed body 6 is mounted on the other side of the air outlet body 3. With the air outlet body 3 as the center, the closed body 6 and the flow divider 4 form a symmetrical structure, which can firstly play a sealing role to prevent air from escaping from the side where the closed body 6 is located; secondly, the overall shape structure is more coordinated and beautiful, which conforms to the aesthetic taste of most users.

[0059] Embodiment 2

[0060] Regarding the preferred embodiment of the flow dividing part 4 in the utility model, in particular, a structural setting for air flow distribution is as follows:

[0061] Reference Figure 6 , Figure 8 , Fig. 9 , Figure 11 to Figure 13 The flow divider portion 4 has a dividing rib 41, and the dividing rib 41 divides the flow divider portion 4 into a large cavity 42 and a small cavity 43. The large cavity 42 is directly connected to the air inlet chamber 31, and the small cavity 43 is connected to the large cavity 42 through an air guide hole 44 provided on the dividing rib 41; the small cavity 43 is arranged side by side and communicated with the upper cavity 361, and the large cavity 42 is arranged side by side and communicated with the middle cavity 362 and the lower cavity 363.

[0062] Thus, all the air in the air inlet chamber 31 will enter the large chamber, and then a small part of the air in the large chamber will enter the small chamber 43 through the air guide hole 44, and then the air flow will be distributed in the flow dividing part 4. Moreover, after the air is divided in the flow dividing part 4, the large chamber 42 is connected with a part of the air outlet chamber 36, and the small chamber 43 is connected with another part of the air outlet chamber 36, and then discharged from the air outlet 33 corresponding to each air outlet chamber 36.

[0063] Reference Figure 5 The further configuration of the air outlet chamber 36 is that the air outlet chamber 36 has an outlet flow channel, and the sizes of the outlet flow channels are different. Specifically, the size of each outlet flow channel can be set according to the needs and is not specifically limited here.

[0064] Reference Figures 4 to 8 , Figure 11 to Figure 13 Based on the structure of different sizes of outlet flow channels, the preferred configuration of the outlet chamber 36 is as follows:

[0065] The air outlet chamber 36 includes an upper chamber 361, a middle chamber 362 and a lower chamber 363, and the outlet flow channel of the middle chamber 362 is larger than the outlet flow channels of the upper chamber 361 and the lower chamber 363. The interior of the air outlet chamber 36 is structurally divided, and the flow channel size of each chamber is limited, so the following effects can be achieved: the middle chamber 362 and its corresponding air outlet 33 are the largest in size, so the air volume is the largest; the upper chamber 361, the lower chamber 363 and their respective corresponding air outlets 33 are small in size, so the air volume is relatively small. Thus, the air volume at the middle position can be kept larger than the air volume at the upper and lower sides, thereby preventing the upper air outlet from having a large air volume and blowing the hair 8 in disorder, thereby preventing the hair 8 from flying around; preventing the lower air outlet from having a large air volume and blowing the handle and the user's hand, thereby preventing the hair from flying around.

[0066] A further configuration of the air outlet chamber 36 is provided, that is, the small chamber 43 is arranged side by side and connected with the upper chamber 361, and the large chamber 42 is arranged side by side and connected with the middle chamber 362 and the lower chamber 363, so as to realize the connection between each chamber and the corresponding chamber. Of course, this configuration is only a preferred solution and is not specifically limited here.

[0067] Reference Fig.13Regarding an arrangement of the lower chamber 363, it is preferred that: the outlet air passage of the lower chamber 363 has a closed end surface 3631 to form a small-sized outlet air passage of the lower chamber 363. The closed end surface 3631 plays a role in blocking the air flow and secondly, plays a role in structural support, even if the air body 3 has sufficient structural strength to withstand a certain external impact force. When in use, air can only enter the corresponding air outlet 33 through the small-sized outlet air passage of the lower chamber 363, so the air outlet volume here can be controlled to a small degree to meet the design and use requirements.

[0068] Reference Fig.11 , with regard to an arrangement of the upper chamber 361, it is preferred that: the air inlet body 2 at least partially intrudes into the outlet flow channel of the upper chamber 361, and the upper chamber 361 has an assembly section 3612 adapted to the air inlet body 2 to form a small-sized outlet flow channel of the upper chamber 361. Thus, firstly, it can realize the reasonable utilization of part of the space, realize the structural connection between the air inlet body 2 and the air outlet body 3, and at the same time, with the air inlet body 2 invading a part of the upper chamber 361, the air flow is blocked to form a small-sized outlet flow channel of the upper chamber 361; secondly, it can play a role of structural support, that is, the air outlet body 3 is supported by the air inlet body 2, and has sufficient structural strength, so as to withstand a certain external impact force. When in use, air can only enter the corresponding air outlet 33 through the small-sized outlet flow channel of the upper chamber 361, so the air outlet volume here can be controlled to a small degree to meet the design and use requirements.

[0069] Embodiment 3

[0070] Based on the structure of any of the above embodiments, this embodiment provides a preferred arrangement of the comb body 5, specifically: Figure 3 , Figure 4 The comb body 5 includes a support block 51 and a plurality of comb teeth 52 fixed on the support block 51. A hollow groove 35 is provided on the air outlet body 3. The support block 51 is detachably connected to the hollow groove 35, and the support block 51 and the hollow groove 35 form a gap 351 to cooperate.

[0071] On the one hand, through the arrangement of the comb teeth 52, a variety of additional functions are added to the air outlet accessory 11 of the utility model. First, it can play the role of combing hair; second, it can control the hair to prevent the hair from being scattered, so as to cooperate with the air outlet and achieve better effects of blowing and hair care; third, it can form a certain gap between hair and hair, and between hair and skin, so as to allow air to enter better, have a larger wind receiving area, and further improve the effects of blowing and hair care.

[0072] On the other hand, a hollow groove 35 is provided, and a gap 351 exists in space when the support block 51 on the comb body 5 cooperates with the hollow groove 35, so that the comb body 5 has an adaptive floating characteristic when in use. Specifically, when the comb body 5 is partially subjected to pressure, the support block 51 moves inward, and at the same time drives the comb teeth 52 to move inward; when the pressure is relieved, it can automatically reset under the action of gravity. Thus, the comb body 5 has functional characteristics similar to those of an air spring, thereby preventing the comb teeth 52 from making hard contact with the hair or skin, and improving the comfort of the comb body 5.

[0073] Embodiment 4

[0074] In this embodiment, the air outlet 33 is gradually narrowed from the back to the front, and cooperates with the arc-shaped guide surface 32 to better transform the ejected airflow into the arc-shaped airflow 34 .

[0075] Embodiment 5

[0076] Reference Fig.10 , Fig.14 In this embodiment, a solution of the hair styling tool 8 in the aforementioned embodiment is provided, that is, the hair styling tool 8 is a hair dryer 7, including a main body section 12 and a handle section 13 arranged perpendicular to each other, and a main body air outlet 121 is provided at the front end of the main body section 12; therefore, the general shape of the hair dryer 7 is "T"-shaped.

[0077] The hair dryer 7 of the present invention also includes the air outlet attachment 11 for the hair styling device 8 as described above, and the air outlet attachment 11 is detachably connected to the main unit air outlet 121. Preferably, the air outlet attachment 11 and the main unit air outlet 121 can be detachably connected by means of a magnetic structure, a threaded structure, a buckle structure, etc., and the specific method is not particularly limited in the present invention.

[0078] 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.
