Description

Technical Field

[0001] This invention relates to the field of curling combs, and more particularly to a curling comb. Background Technology

[0002] Chinese Patent No. CN221265456U discloses a hair dryer curling comb assembly with uniform airflow from both the top and bottom. The assembly includes a curling comb housing and air outlets and comb teeth disposed on the curling comb housing. An air guide column is disposed inside the curling comb housing, and several air guide plates are disposed on the air guide column. The space between adjacent air guide plates is aligned with the air outlets on the curling comb housing. The cross-sectional area of ​​the several air guide plates on the air guide column gradually increases from bottom to top.

[0003] In the above structure, several guide vanes on the air guide column guide the gas blown into the curling comb housing, causing the gas to flow out from the air outlets at different heights on the curling comb housing. This makes the gas flowing out from the air outlets at various heights on the curling comb housing more uniform. However, when the air guide vane at the bottom of the air guide column guides the gas, some gas will flow into the next air guide vane through the gap between the guide vane and the inner wall of the curling comb housing. At this time, the two types of gas with different flow directions will interfere with each other, generating turbulence and eddies, which will increase the noise. Summary of the Invention

[0004] This invention addresses the drawback of existing technologies where the air guide vanes located at the bottom of the air guide column interfere with the gas flowing to the next air guide vane, generating turbulence and eddies, thus increasing noise. The invention provides a curling comb.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A curling comb includes a housing, comb teeth disposed on the side wall of the housing, and a first air vent. An air guide assembly is disposed inside the housing to guide the gas entering the housing. The air guide assembly includes an inner liner disposed inside the housing. The inner liner is a constricted shape that gradually narrows from the bottom to the top of the housing. A second air vent is opened on the side wall of the inner liner, which allows the gas entering the inner liner to be blown out of the inner liner. An air guide plate is protruding from the side wall of the inner liner, and the air guide plate guides the gas blown out from the second air vent to the first air vent.

[0006] With the above solution, since there is an inner liner inside the shell, when gas enters the shell, it first enters the inner liner. Because the inner liner is shaped like a constricted opening that gradually narrows from the bottom to the top of the shell, when the gas enters the inner liner, it is blown out from the second vent on the side wall of the inner liner. When the gas is blown out from the second vent, it collides with the air guide plate on the outer wall of the inner liner. At this time, the air guide plate will turn the gas, so that the gas blown out from the second vent will be discharged from the first vent. This reduces the probability of turbulence and eddies in the gas entering the inner liner, reduces the noise generated by the curling comb during use, and improves the user's comfort. At the same time, because the inner liner is shaped like a constricted opening that gradually narrows from the bottom to the top of the shell, the gas flow rate entering the inner liner will gradually increase, thereby increasing the speed at which the gas is blown out from the second vent located at the top of the inner liner.

[0007] Preferably, an air guide tube is connected to one end of the inner liner near the top of the shell, and the air guide tube discharges the gas blown into the inner liner from the first air vent near the top of the shell side wall.

[0008] Preferably, a positioning and overlapping component is provided between the inner liner and the outer shell for positioning and overlapping the inner liner with the inner wall of the outer shell.

[0009] Preferably, the positioning overlap component includes an overlap ring protruding from the side wall of the inner liner near the bottom and an overlap plate disposed on the inner wall of the shell, which abuts against the overlap ring after the inner liner is installed in a designated position inside the shell.

[0010] Using the above solution, the overlapping ring set on the outer wall of the inner liner can overlap with the overlapping plate set inside the shell when the inner liner is installed into the shell, thereby positioning the inner liner.

[0011] Preferably, a guide component is provided between the inner wall of the shell and the inner liner to guide the installation of the inner liner and prevent the inner liner from deflecting after it is installed inside the shell.

[0012] Preferably, the guiding component includes a guide plate extending vertically on the inner wall of the housing and a guide groove provided on the inner liner for the guide plate to be inserted when the inner liner is installed inside the housing.

[0013] Using the above solution, the guide plate set on the inner wall of the shell can be inserted into the guide groove set on the inner liner when the inner liner is installed into the shell, thereby guiding the installation of the inner liner. At the same time, when the inner liner is installed into the shell, since the guide plate on the inner wall of the shell and the guide groove on the inner liner are interlocked, it can also prevent the inner liner from deflecting in the shell, so that the inner liner can more stably guide the gas entering the inner liner to the first air outlet on the shell.

[0014] Preferably, the inner wall of the shell is provided with several guide plates in all directions, and the number and position of the guide grooves on the inner liner correspond one-to-one with the guide plates.

[0015] By adopting the above scheme, several guide plates are provided around the inner wall of the shell and guide grooves are provided on the inner liner. This makes the force on the inner liner more uniform after it is installed inside the shell, thereby further reducing the probability of the inner liner deflecting inside the shell.

[0016] Preferably, several guide grooves are circumferentially located on the overlapping ring.

[0017] Preferably, the shell includes a hollow cylinder and a base and a top cover respectively provided at the upper end of the cylinder. After the cylinder, base and top cover are assembled, an internal space is formed for placing the inner liner and the air guide tube. When the overlapping ring on the inner liner overlaps the overlapping plate, the end of the air guide tube away from the inner liner abuts against the bottom surface of the top cover.

[0018] With the above solution, the space can be used to place the inner liner and the air guide tube. When the overlapping ring on the inner liner overlaps with the overlapping plate inside the shell, the end of the air guide tube away from the inner liner is set to abut against the bottom surface of the upper cover, thereby reducing the probability that the inner liner and the air guide tube will move upward due to the push of the gas blown into them.

[0019] This invention, by employing the above technical solutions, has significant technical effects: Because an inner liner is installed inside the shell, when gas enters the shell, it first enters the inner liner. Since the inner liner is shaped like a constricted opening that gradually narrows from the bottom to the top of the shell, when gas enters the inner liner, it is blown out through a second vent on the side wall of the inner liner. As the gas exits through the second vent, it collides with a guide plate on the outer wall of the inner liner. This guide plate then redirects the gas, causing it to exit through the first vent. This reduces the probability of turbulence and eddies in the gas entering the inner liner, lowers the noise generated during use, and improves user comfort. Simultaneously, because the inner liner is shaped like a constricted opening that gradually narrows from the bottom to the top of the shell, the speed at which the gas enters the inner liner and enters the guide duct at the top of the inner liner gradually increases, thereby increasing the speed at which the gas exits through the first vent located at the top of the side wall of the shell.

Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0023] Example A type of curling comb, reference Figure 1 , Figures 5-6 The system includes a housing 1, comb teeth 3 disposed on the side wall of the housing 1, and a first air vent 201. The comb teeth 3 and the first air vent 201 are circumferentially disposed on the side wall of the housing 1, and the comb teeth 3 and the first air vent 201 on the same horizontal plane are in one layer. In this embodiment, the comb teeth 3 and the first air vent 201 are disposed in several layers. An air guide assembly is disposed inside the housing 1 to guide the gas entering the housing 1. The air guide assembly includes an inner liner 4 disposed inside the housing 1. The inner liner 4 is a constricted shape that gradually narrows from the bottom to the top of the housing 1. A second air vent 202 is opened on the side wall of the inner liner 4, which allows the gas entering the inner liner 4 to be blown out of the inner liner 4. The side wall of the inner liner 4 is convex. A guide plate 6 is provided, which guides the gas blown out from the second air vent 202 to the first air vent 201. A guide tube 5 is connected to one end of the inner liner 4 near the top of the shell 1. A third air vent 203 is provided on the side wall of the guide tube 5. The guide tube 5 discharges the gas blown into the inner liner 4 through the third air vent 203 from the first air vent 201 near the top of the side wall of the shell 1. In this embodiment, the number and position of the second air vents 202 are the same as those of the first air vents 201. A number of guide plates 6 are provided on the inner liner 4 along the axial direction of the shell 1 to guide the gas blown out from the second air vent 202 to the first air vent 201. The size of the guide plate 9 is the same as the inner diameter of the shell 1.

[0024] refer to Figures 2-5 A positioning overlap component is provided between the inner liner 4 and the shell 1 for positioning the inner liner 4 to overlap the inner wall of the shell 1. The positioning overlap component includes an overlap ring 7 protruding from the side wall of the inner liner 4 near the bottom and an overlap plate 8 provided on the inner wall of the shell 1 that abuts against the overlap ring 7 after the inner liner 4 is installed in the designated position inside the shell 1.

[0025] A guide component is provided between the inner wall of the shell 1 and the inner liner 4 to guide the installation of the inner liner 4 and prevent the inner liner 4 from deflecting after it is installed inside the shell 1. The guide component includes a guide plate 9 extending vertically on the inner wall of the shell 1 and a guide groove 10 provided on the inner liner 4 for the guide plate 9 to be inserted when the inner liner 4 is installed inside the shell 1. Several guide plates 9 are provided around the inner wall of the shell 1. The number and position of the guide grooves 10 provided on the inner liner 4 correspond one-to-one with the guide plates 9. Several guide grooves 10 are provided around the overlapping ring 7.

[0026] refer to Figure 6 The shell 1 includes a hollow cylindrical body 102 and a base 103 and a top cover 101 respectively provided on the upper end of the cylindrical body 102. After the cylindrical body 102, the base 103 and the top cover 101 are assembled, an internal space 11 is formed for placing the inner liner 4 and the air guide 5. When the overlapping ring 7 on the inner liner 4 overlaps the overlapping plate 8, the end of the air guide 5 away from the inner liner 4 abuts against the bottom surface of the top cover 101.

[0027] Specific air guiding process: When gas is blown into the housing 1, it first enters the inner liner 4 inside the housing 1. The inner liner 4 is shaped like a constricted opening that gradually narrows from the bottom to the top of the housing 1. Therefore, when gas is blown into the inner liner 4, it will be blown out from the second air vent 202 on the side wall of the inner liner 4. When the gas is blown out from the second air vent 202, it will collide with the air guide plate 6, causing the gas to change direction. This will cause the gas blown out from the second air vent 202 to be discharged from the first air vent 201 to the outside of the housing 1. At the same time, the gas that does not exit from the second air vent 202 on the inner liner 4 will enter the top of the inner liner. Inside the air duct 5, and because the inner liner 4 is shaped like a constricted opening that gradually narrows from the bottom to the top of the shell 1, the speed at which the gas enters the air duct 5 increases. The gas entering the air duct 5 will gradually be blown out from the third air vent 203 on the side wall of the air duct 5, and the gas blown out from the third air vent 203 will gradually be discharged from the first air vent 201 near the top of the side wall of the shell 1. This makes the airflow of the curling comb more uniform and reduces the probability of turbulence and eddies caused by the collision of the gas entering the inner liner 4 during use. This reduces the noise of the curling comb during use and improves the user experience.
