Detailed implementation mode

[0019] To make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.

[0020] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: an automatic adsorption and curling structure of a hair dryer, including a connecting air supply head 1, an adsorption heating cover 2 is sleeved outside the connecting air supply head 1, the internal space of the adsorption heating cover 2 is communicated with the internal space of the connecting air supply head 1, the adsorption heating cover 2 includes an inner cover cylinder 201, an outer cover cylinder 202 is sleeved outside the inner cover cylinder 201, the inner cover cylinder 201 and the outer cover cylinder 202 are coaxially rotatably connected, and a plurality of groups of through grooves corresponding to each other and distributed in a ring are opened on the outer walls of the inner cover cylinder 201 and the outer cover cylinder 202.

[0021] Please refer to Figure 2 , the connecting air supply head 1 includes a connector 101, one end of the connector 101 is communicated with one end of a connecting air duct 102, the other end of the connecting air duct 102 is communicated with an air outlet head 103, and uniformly distributed through holes 104 are opened on the outer circumferential wall of the connecting air duct 102.

[0022] The connector 101 is used to connect the whole to the air outlet end of the hair dryer. The air flow output by the hair dryer enters the connecting air duct 102 from the connector 101 and then is blown out from the air outlet head 103. A plurality of through holes 104 are arranged on the outer wall of the connecting air duct 102, so that the inside of the connecting air duct 102 is communicated with the inside of the inner cover cylinder 201. When high-speed gas passes through the inside of the connecting air duct 102, the air pressure inside the connecting air duct 102 decreases, and the external high pressure enters the connecting air duct 102 through the through grooves arranged on the outer walls of the inner cover cylinder 201 and the outer cover cylinder 202 and is discharged from the air outlet head 103 along with the air flow. Thus, a suction force towards the inside is generated in the through grooves arranged on the outer wall of the outer cover cylinder 202, so that the hair can be adsorbed and wound around the outer wall of the outer cover cylinder 202, and the hair is heated and shaped by the heat of the air flow to achieve the curling effect.

[0023] Furthermore, the connector 101, the connecting air duct 102 and the air outlet head 103 are integrally arranged.

[0024] The three-in-one setting can enhance the overall structural strength, support the whole to improve stability.

[0025] Furthermore, a number of evenly distributed clamping grooves 105 are provided on the outer circumferential wall of the connector 101.

[0026] A corresponding clamping member is provided on the outer wall of the air outlet end of the hair dryer. During use, the connector 101 is sleeved outside the air outlet end of the hair dryer, so that the clamping member is inserted into the clamping groove 105, and the connector 101 is rotated to complete the clamping of the two to complete the installation, maintaining stability during use.

[0027] Please refer to Figures 2 to 4 , both ends of the inner cover cylinder 201 are fixedly connected to the connector 101 and the air outlet head 103 respectively. Annular slide rails 203 are integrally provided on the outer walls at both ends of the inner cover cylinder 201, and corresponding annular sliding grooves 204 are provided on the inner walls at both ends of the outer cover cylinder 202. Each annular slide rail 203 is slidably connected to the corresponding annular sliding groove 204.

[0028] The inner cover cylinder 201 is fixedly installed on the whole connecting air outlet head 1. The outer cover cylinder 202 can rotate independently relative to the inner cover cylinder 201 through the cooperation of the annular slide rail 203 and the annular sliding groove 204. When the outer cover cylinder 202 rotates at an angle relative to the inner cover cylinder 201, the overlapping area of a corresponding group of through grooves changes. By adjusting the overlapping area of the through grooves, the air flow velocity entering the inside of the inner cover cylinder 201 is adjusted, thereby changing the suction force. The greater the air flow velocity, the greater the suction force, which can facilitate the user to flexibly adjust according to factors such as hair length and softness, avoiding the limitation caused by only adjusting the fixed gear of the hair dryer.

[0029] Furthermore, the outer wall of the inner cover cylinder 201 is in contact with the inner wall of the outer cover cylinder 202, and a damping structure is provided therebetween.

[0030] The inner cover cylinder 201 and the outer cover cylinder 202 are made of metal materials, which have high durability and corrosion resistance, and also have high heat conduction effect. The heat of the air flow output by the hair dryer can be conducted to the outer wall of the outer cover cylinder 202 to heat and shape the hair. The contact between the outer wall of the inner cover cylinder 201 and the outer wall of the outer cover cylinder 202 can ensure the airtightness between the two, ensuring that the external air flow can only enter the connecting air duct 102 from the corresponding through grooves, thereby improving the effect of changing the flow velocity by adjusting the overlapping area of the through grooves. The damping structure provided therebetween can limit the relative position after the adjustment is completed, avoiding the continuous independent rotation of the outer cover cylinder 202 caused by the air flow and affecting the use stability.

[0031] Further, each group of through slots are respectively a communication slot 205 and an air inlet slot 206. The communication slot 205 is formed through the outer wall of the inner housing cylinder 201, and the air inlet slot 206 is formed through the outer wall of the outer housing cylinder 202, and the area of the communication slot 205 is larger than that of the air inlet slot 206.

[0032] The vertical inner walls on both sides of each communication slot 205 are on the extension line of the radius of the inner housing cylinder 201 to ensure the air inlet effect. The vertical inner wall of each air inlet slot 206 is an arc surface, and the air inlet slot 206 is an overall arc structure extending in the inner wall of the outer housing cylinder 202 to reduce the situation that hair is sucked into the interior of the inner housing cylinder 201. The area of the communication slot 205 is larger than that of the air inlet slot 206, so that the overlapping area of the air inlet slot 206 and the corresponding communication slot 205 is adjusted by rotating the outer housing cylinder 202 to change the suction force.

[0033] Working principle: During use, the connector 101 is sleeved outside the air outlet end of the hair dryer, so that the clamping member provided on the outer wall of the air outlet end of the hair dryer is inserted into the clamping groove 105, and the connector 101 is rotated to complete the clamping and installation. The hair dryer is started to blow air into the connecting air duct 102, and the air flow enters the connecting air duct 102 and is then output by the air outlet head 103. By accelerating the flow rate, the air pressure inside the connecting air duct 102 is reduced, so that an air pressure difference is formed inside the connecting air duct 102 and the overall exterior. The air in the external high-pressure environment sequentially passes through each group of corresponding air inlet slots 206 and communication slots 205 and then enters the connecting air duct 102 with a relatively lower air pressure through the through holes 104, so that suction is formed at the air inlet slot 206, and the hair can be adsorbed and wound around the outer wall of the air inlet slot 206. The heat of the air flow output by the hair dryer is conducted to the surface of the air inlet slot 206 to heat and shape the hair to achieve the curly hair effect. By setting the adsorption heating cover 2 into two parts, namely the inner housing cylinder 201 and the outer housing cylinder 202, the overlapping area of the communication slot 205 and the air inlet slot 206 is adjusted by rotating the outer housing cylinder 202 to change the flow rate of the external air entering the interior of the connecting air duct 102, thereby adjusting the adsorption force, which is convenient for the user to flexibly adjust according to factors such as the length and softness of the hair, and avoiding the limitation caused by only adjusting the fixed gear of the hair dryer.

[0034] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
