Description

Technical Field

[0001] The utility model relates to the technical field of hairdressing products, in particular to a comb-teeth hair absorbing structure and a hair dryer comprising the same. Background Art

[0002] A hair dryer is a personal care product that works by converting electrical energy into heat energy. It dries damp or wet hair. Traditional hair dryers direct hot air onto the hair, causing it to form a curly structure, which is not what people who prefer straight and smooth hairstyles are looking for. After frequent use, hair becomes frizzy and people need to go to the barber shop regularly for hair straightening.

[0003] The applicant has designed a hair dryer with a new structure for users with straight hair, which can dry wet hair while avoiding the formation of curly structures. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a comb teeth hair adsorption structure and a hair dryer including the same.

[0005] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: The present invention relates to a comb-tooth structure for absorbing hair, comprising a plate body having an internal air cavity, the plate body having an air inlet end communicating with the air cavity, the plate body having a supporting surface, the supporting surface having a row of comb teeth disposed along the length of the plate body, the comb teeth having air outlet holes communicating with the air cavity, the comb teeth being straight and arranged perpendicular to the supporting surface, the tops of the comb teeth having an end arc-shaped surface, the comb teeth having tooth blades, and the air outlet holes being disposed on one side or both sides of the tooth blades. The comb-tooth air outlet holes of the present invention can absorb hair, achieving one-way blowing from the roots to the tips of the hair, achieving the effects of straightening, smoothing, and preventing hair from flying.

[0006] Preferably, the cross section of the comb teeth is roughly elliptical and flat, with a length L>width W, width W≥5mm, and a spacing D between two adjacent comb teeth≤5mm.

[0007] Preferably, the comb teeth have an air guide duct inside, the air guide duct having a curved guide surface. The fluid is guided by the curved guide surface to the air outlet and then flows against the supporting surface. When hair is dried between the comb teeth, it can be used as an air comb-style hair dryer. Even if the hair is not grasped by hand or a plate is added to clamp the hair, the hair will not be blown away, achieving a smooth and dry effect.

[0008] Preferably, a guide plate is provided within the air cavity, the guide plate forming at least one crest and trough. The crest has a fluid diversion characteristic. When fluid flows toward the crest in the air cavity, the fluid is divided into two streams. One stream is directly directed toward the air outlet, while the other stream continues to flow along the crest to the trough and flows along the rising surface of the trough toward the corresponding air outlet, so that all air outlets can achieve air discharge, improving the air discharge effect.

[0009] Preferably, a heating wire winding installation cavity is enclosed between the upper surface of the guide plate and the lower surface of the supporting surface.

[0010] A wind comb type hair dryer comprises an air supply system and a comb teeth hair adsorbing structure; the air supply system is connected to the air inlet end to provide the fluid to the air cavity.

[0011] A clamp-type hair dryer includes an air supply system and a comb-tooth structure for attracting hair. The air supply system is connected to the air inlet to provide the fluid to the air cavity. The dryer also includes a cover. The rear ends of the cover and the plate are hingedly fixed to each other, and the front ends of the cover and the plate can be opened or closed. When the cover and plate are closed, a drying air cavity for drying hair is formed. The drying air cavity has a hair inlet and an outlet, and the comb teeth are arranged near the outlet. The comb teeth are arranged near the outlet, so that the hair is exposed to the maximum amount of fluid, thereby improving drying efficiency.

[0012] The utility model forms a clamp-type hair dryer with a cover. Combing hair with the comb teeth heats the hair, achieving a straightening and smoothing effect. The cover and plate form two clamping arms that clamp the hair for combing, effectively confining the hair. The comb teeth disperse the hair between two adjacent comb teeth, allowing the hair to pass through the comb teeth. This ensures that the hair passes through the comb teeth in a relatively dispersed manner during combing, allowing the hair to fully contact the comb teeth for heating. This allows for better combing and straightening, improving the straightening effect. When closed, a drying air chamber is provided for drying hair, increasing fluid pressure and facilitating hair drying.

[0013] Preferably, the cover is provided with a comb tooth receiving groove. When the cover and the plate are closed, the comb teeth are stored in the comb tooth receiving groove, and at least a portion of the air outlet is exposed outside the comb tooth receiving groove. The comb tooth receiving groove makes the hair dryer more compact and easier to carry and store.

[0014] Preferably, the starting end is provided with a cover step portion and a plate step portion, and when the cover and the plate are closed, the cover step portion and the plate step portion clamp the hair in the drying air chamber.

[0015] Preferably, the front and rear ends of the cover body are respectively provided with a front baffle and a rear baffle, and the front and rear ends of the plate body are respectively provided with a second front baffle and a second rear baffle. When the cover body and the plate body are closed, the front and second front baffles of the cover body are relatively closed, and the rear and second rear baffles of the cover body are relatively closed, thereby enclosing a semi-enclosed chamber. At the same time, the drying air chamber is prevented from being flattened and at least a height H is maintained, H ≥ 3mm. This allows the fluid to effectively and centrally act on the hair, achieving higher efficiency.

[0016] Preferably, the comb teeth are formed by the upward protrusion of the supporting surface. The comb teeth are integrally formed with the cover, which reduces the number of parts that need to be manufactured and assembled separately, reducing material and assembly costs. The integrally formed comb teeth have better consistency in size and shape, avoiding the cumulative errors that may exist between the comb teeth and the cover. At the same time, the surface is smoother, with fewer seams and connection points, making the final product more refined in appearance.

[0017] Preferably, each adjacent comb tooth has an interdental channel for hair to pass through.

[0018] The beneficial effects of the present invention are as follows: the present invention relates to a clamp-type hair dryer with comb-teeth air outlets, wherein comb-teeth with air outlets are provided on a cover or a plate to grip the hair. When the clamp-type hair dryer moves from the hair roots to the hair tips, the hair is tightened by the closed cover and plate. When fluid or heated fluid flows from the air chamber to the air outlets, the fluid flows from the air outlets into the drying air chamber. The hair follows the fluid flowing out of the comb-teeth and floats in the comb-teeth flow channel. The hair is actually acted upon by the fluid along the hair roots to the hair tips, thereby achieving a straightened appearance while drying the hair.

[0019] The present invention also arranges a guide plate inside the wind cavity, and the guide plate has a curved surface for guiding the wind flow, and the curved surface forms at least one crest and trough. When the fluid flows to the crest in the wind cavity, the fluid is divided into two streams, one of which is directly guided to flow to the air outlet, and the other stream continues to flow along the crest to the trough, and flows along the rising surface of the trough to the corresponding air outlet, so that all the air outlets can achieve air outlet, thereby improving the air outlet effect.

[0036] Example 1

[0037] See also Figure 1-4 As shown, the present invention relates to a comb-tooth hair-absorbing structure, comprising a plate body 2, including an air cavity 3 and / or a heating wire winding 32 disposed therein. The plate body 2 is provided with an air inlet end 16 that is in communication with the air cavity 3. The supporting surface 15 of the plate body 2 is provided with a plurality of comb teeth 23 for combing hair 5. The surfaces of the comb teeth 23 are provided with air outlet holes 231. The comb teeth 23 are internally provided with air guide ducts 233, which connect the air outlet holes 231 and the air cavity 3. A guide plate 31 is disposed within the air cavity 3. The guide plate 31 has at least one curved surface on a side facing the air outlet hole 231, forming at least one crest 311 and trough 312. The guide plate 31 guides fluid from the air cavity 3 to the air outlet hole 231. In this embodiment, the trough 312 is the portion of the arc surface that is concave in the direction away from the air outlet 231, while the crest 311 is the portion of the arc surface that is convex in the direction close to the air outlet 231. The crest 311 and the trough 312 are clearly alternating, forming a wave-like shape. The guide plate 31 of this structure provides an installation space for the heating wire winding 32. In this embodiment, the guide plate 31 and the lower surface of the supporting surface 15 enclose a heating wire winding 32 installation cavity, wherein the crest 311 has a fluid diversion characteristic, such as Figure 2 As shown, when the fluid flows toward the crest 311 in the wind cavity 3, the fluid is divided into two streams, one of which is directly guided to the corresponding air outlet holes 231 of the first, second and third comb teeth 23 and discharged to the outside, and the other stream continues to adhere to the crest 311 and flow to the trough 312 and then flows along the plate surface of the guide plate 31 to the air outlet holes 231 of the fourth and fifth comb teeth 23 and discharged to the outside. The fluid fills the wind cavity 3 completely with the guidance of the guide plate 31, so that all the air outlet holes 231 can realize air outlet, thereby improving the air outlet effect. Assuming that the guide plate 31 is cancelled, due to the higher mainstream of the fluid, the main fluid will be concentrated to the air outlet holes 231 of the fourth and fifth comb teeth 23 for discharge, and the air outlet volume of the air outlet holes 231 of the first, second and third comb teeth 23 will be reduced, resulting in uneven air outlet from each air outlet hole 231.

[0038] In this embodiment, the heating wire winding 32 is arranged in the wind cavity 3, and the heating wire winding 32 is arranged at one end close to the air outlet 231. The heat generated by the heating wire winding 32 only needs to pass through a very short flow path in the wind cavity 3 with the fluid to reach the air outlet 231 and be discharged to the outside to act on the hair 5.

[0039] In this embodiment, the comb teeth 23 have tooth blades 235, and the air outlets 231 are provided on one side or both sides of the comb tooth side surfaces 236 of the tooth blades 235. The outermost comb teeth 23 have only one air outlet 231, which is inclined to the adjacent comb teeth 23. The remaining comb teeth 23 have a pair of air outlets 231. The pair of air outlets 231 are symmetrically arranged on the comb tooth side surfaces 236 on both sides with the tooth blades 235 as the center axis. The tooth blades 235 are located downstream of the pair of air outlets 231. According to the Coanda effect, when the fluid flows out at a high speed, the tooth blades 235 form a negative pressure to absorb the hair, thereby achieving the effect of smoothing and drying the hair. When the hair dryer is working on the hair 5, combined with Figure 11 As shown, the hairs 5 are separated by the comb teeth 23 to form inter-hair spaces 26. The fluid is blown out from the air outlet holes 231 on both sides and continues to move forward parallel to and adsorbing the hairs 5. The fluid fully acts on the hairs 5. Due to the existence of the inter-hair spaces 26, the fluid will not flow back due to too many hairs 5. At this time, the fluid flows smoothly, the fluid noise is relatively small, and the hair detangling and drying effects are relatively ideal.

[0040] Further, combined Figure 12 As shown, a guide curved surface 234 is provided in the air guide duct 233 of the comb teeth 23 and near the air outlet 231. The guide curved surface 234 is concave toward the top of the comb teeth 23. When the fluid flows from the air cavity 3 into the air guide duct 233, the wind can flow along the guide curved surface 234. After the fluid flows out of the air outlet 231, the fluid will flow along the supporting surface 15 of the plate body 2. When the comb teeth 23 face upwards and the hair 5 is placed between the comb teeth 23 from above, the overall Figure 11 and Figure 12 As shown, since the hair 5 also has gravity, the hair 5 will not be blown away. The hair 5 will stick to the supporting surface 15 and float in the wind. When the comb teeth 23 are moved away from the hair roots, the hair 5 will slide between the comb teeth 23 and on the supporting surface 15. The whole process can achieve the effects of drying, softening, straightening and combing the hair 5.

[0041] Example 2:

[0042] See also Figure 5-10 As shown, the difference between the second embodiment and the first embodiment is that a cover body 1 is added to the plate body 2 to form a clamp-type hair dryer, the rear ends of the cover body 1 and the plate body 2 are hinged and fixed to each other, and the front ends of the cover body 1 and the plate body 2 can be opened or closed.

[0043] The inner walls of the cover 1 and plate 2 are roughly parallel to each other, forming a drying air chamber 4 for fluid flow. When the cover 1 and plate 2 are clamped and closed, the pressure in the drying air chamber 4 increases, facilitating the drying of the hair 5. The drying air chamber 4 has a hair entry end 41 and a departure end 42. As the hair dryer moves from the root to the tip of the hair, the hair 5 passes through the dryer and slides out of the dryer at the departure end 42, which is closer to the root. When combing hair, the comb teeth 23 are kept as close to the root as possible. As the hair dryer moves from the root to the tip, the hair 5 slides out of the comb teeth 23 against the wind. An outlet 231 is located near the departure end 42 for the fluid inside to flow out. The outlet 231 discharges fluid toward the hair entry end 41. The cover 1 and / or the plate 2 are provided with an air cavity 3; the air cavity 3 of the cover 1 and / or the plate 2 is provided with a guide plate 31 as described in the first embodiment. The cover 1 and / or the plate 2 are provided with a plurality of comb teeth 23, combined with Figure 11 As shown, the comb teeth 23 are provided with air outlet holes 231, which are three-dimensional air outlets with a roughly V-shaped longitudinal cross-section. The air outlet holes 231 connect the air chamber 3 with the drying air chamber 4. The fluid flows from the air chamber 3 to the air outlet holes 231, and the fluid flows from the air outlet holes 231 into the drying air chamber 4 to act on the hair 5, and is finally discharged to the outside from the side of the hair inlet end 41.

[0044] In the second embodiment, the plate body 2 is provided with a plurality of comb teeth 23, referring to Figure 6 and Figure 11 As shown, the comb teeth 23 are arranged near the starting end 42 of the plate body 2. A plurality of the comb teeth 23 are arranged on the plate body 2 at intervals along the length of the plate body 2. There is an inter-tooth channel 24 between each two adjacent comb teeth 23 for the hair 5 to pass through. The comb teeth 23 are provided with air outlet holes 231. Figure 11 As shown, the comb teeth 23 have a roughly oval, flat cross-section, with a length L greater than a width W. The comb teeth 23 separate the hairs 5, forming inter-hair gaps 26 between adjacent hair bundles 5. The width W is ≥ 5 mm, ensuring a sufficiently wide inter-hair gap 26 to prevent fluid backflow due to excessive hair 5. The distance D between two adjacent comb teeth 23 is ≤ 5 mm, preventing excessive hair 5 from being combed between them and affecting hair drying efficiency. The air outlet holes 231 are positioned toward the hair inlet end 41, with the air outlet holes 231 of each pair of adjacent comb teeth 23 inclined at an angle to each other. When fluid is ejected from the air outlet holes 231, it exerts a certain forward pulling force on the hair 5 within the drying air chamber 4, pulling the hair 5 forward toward the hair tips, causing the hair 5 to float with the wind, achieving the desired effect of drying, softening, straightening, and combing the hair 5.

[0045] Furthermore, the comb teeth 23 are relatively flat and fin-shaped, and are vertically arranged on the plate 2. The tops of the comb teeth 23 are provided with curved end surfaces 232. When clamping the hair 5, the curved end surfaces 232 can reduce the problem of pulling or friction on the hair 5 during the clamping operation, allowing the hair 5 to enter the inter-tooth channels 24 between the comb teeth 23 more smoothly, reducing the risk of damage to the hair 5.

[0046] Furthermore, the cover body 1 is provided with a comb tooth receiving groove 13 that matches the shape of the comb teeth 23. When the cover body 1 and the plate body 2 are closed, the top of the comb teeth 23 will enter the comb tooth receiving groove 13, thereby reducing the upper and lower spaces of the drying air chamber 4 after the cover body 1 and the plate body 2 are closed, making the drying air chamber 4 more slender, further limiting the range of the fluid, effectively increasing the flow rate of the fluid in the drying air chamber 4, and allowing the hair 5 to float and move along the drying air chamber 4.

[0047] In order to avoid gaps between the front and rear ends of the cover 1 and the plate 2 due to the drying air chamber 4 after closing and to ensure that the drying air chamber 4 is not excessively flattened, in this embodiment, the front and rear ends of the cover 1 in the longitudinal direction are respectively provided with a front cover baffle 11 and a rear cover baffle 12, and the front and rear ends of the plate 2 in the longitudinal direction are respectively provided with a second front baffle 21 and a second rear baffle 22. When the cover 1 and plate 2 are closed, the front baffle 11 and the second front baffle 21 of the cover are relatively closed, and the rear baffle 12 and the second rear baffle 22 of the cover are relatively closed, thereby enclosing a semi-enclosed chamber. At the same time, the drying air chamber 4 is prevented from being flattened and at least maintains a height H, H ≥ 3mm. Although the lower the height of the drying air chamber 4, the greater the wind pressure therein, which is more conducive to the drying efficiency of the hair 5, when the wind pressure is high, the wind noise will also increase. In particular, when the height H of the drying air chamber 4 is less than 3mm, the noise will be harsh, the fan load will be too large, and the fan temperature will increase significantly, which will affect the fan life and user experience. When the fluid flows out of the air outlet 231, the semi-enclosed chamber can effectively change and guide the direction of the fluid, helping to control the fluid within a certain range and make the wind force more concentrated within a certain range, thereby improving the blowing effect.

[0048] Example 3:

[0049] See also Figure 10As shown, the difference between this third embodiment and the second embodiment lies in the fact that the starting ends 42 of the cover 1 and plate 2 are provided with a cover step 14 and a plate step 25. When the cover 1 and plate 2 are closed, these cover steps 14 and plate steps 25 serve to confine the hair 5, better confining it within the drying chamber 4. This helps to squeeze out moisture from the hair 5 when the hair 5 is relatively large and wet. Furthermore, the smaller the distance between the cover step 14 and plate step 25, the more effective the semi-enclosed chamber becomes after the cover 1 and plate 2 are closed. This effectively increases the air pressure in the drying chamber 4, allowing the hair 5 to flow more freely along the drying chamber 4, further enhancing the hair-smoothing effect.

[0050] The above embodiments are merely descriptions of preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering technicians in this field should fall within the scope of protection determined by the claims of the present invention.
