Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of hair dryers, and in particular relates to an electric hair dryer air inlet structure and an electric hair dryer. Background Art
[0002] As a common personal care appliance, hair dryers are becoming more and more popular in households. In order to increase the outlet wind speed, most existing hair dryers use high-speed fans with a rotation speed of more than 100,000. The principle is to use a high-speed fan to generate a high-speed airflow, which is heated by the heating wire and ejected from a narrow slit to dry wet hair and other objects.
[0003] The operation of a high-speed hair dryer is to form a high-pressure airflow in the airflow channel through a high-speed fan, so a negative pressure will be formed at the position of the air inlet, and the closer to the air inlet, the greater the pressure, so the position of the air inlet will cause air squeezing, which will affect the air intake effect. In order to solve this technical problem, a Chinese patent document with publication number CN220308603U discloses a hair dryer, which specifically discloses that the hair dryer includes a handle and a shell, the handle is arranged on the bottom side of the shell and extends downward, a cavity is arranged in the shell, the tail end of the shell has a first air inlet, the front end of the shell has an air outlet, and the first air inlet and the air outlet form a first air duct with the cavity; an installation cavity is arranged in the handle for installing a control circuit, the upper end of the installation cavity is connected to the cavity, and the connecting port is located between the first air inlet and the fan of the hair dryer; a second air inlet is arranged at the lower end of the handle, and the second air inlet and the installation cavity form a second air duct connected to the first air duct. The shell includes an outer shell and a cylinder. The outer side of the cylinder is provided with support ribs, which are supported on the inner wall of the outer shell, so that an airflow channel is formed between the outer side of the cylinder and the inner side of the outer shell, and the tail end of the airflow channel is connected with the first air duct; the fan is arranged in the cylinder; the front end of the cylinder is provided with a limiting ring, which is used to limit the inner wall of the outer shell. The tail end of the cylinder is provided with a support frame extending out of the outer shell, and a support ring supported on the inner side of the outer shell, and the support frame is sleeved with a filter mesh shell; the tail end of the outer shell is also covered with a rear end cover, and the filter mesh shell is accommodated in the rear end cover; the rear end cover is provided with a plurality of ventilation holes. Among them, the support frame is a hollow structure, and the end side and surrounding of the rear end cover are provided with air inlets, so that air can enter from the surrounding and end face of the rear cover, and the structure of the support frame is a hollow structure, and it only plays a supporting role for the filter mesh shell. Therefore, the high-pressure airflow enters the filter housing directly into the air duct. Since the space inside the filter housing is large, after the airflow enters, the airflow pressure in the middle is greater than the pressure of the side airflow, and there will be airflow movement, which not only affects the air intake, but also causes loud noise problems. Utility Model Content
[0004] The utility model aims to provide an air inlet structure for a hair dryer, so as to solve the problem that the air inlet of the existing high-speed hair dryer affects the air intake and causes loud noise.
[0005] To achieve the above-mentioned purpose, an embodiment of the utility model provides an air inlet structure for an electric hair dryer, comprising a hair dryer body, an air duct is provided inside the hair dryer body, and an air inlet is provided at the tail end of the air duct. It also comprises a flow divider and an air inlet cover; a bracket is provided at the tail end of the hair dryer body, and the bracket comprises a mounting portion and an air inlet duct; the mounting portion is used to be mounted at the tail end of the hair dryer body, and the mounting portion is provided with a through hole; a supporting portion is extended from the mounting portion, the air inlet duct is connected to the supporting portion, and the outer side of the air inlet duct and the through hole form a side air duct; the flow divider is sleeved on the bracket, a plurality of air holes are distributed on the end side of the flow divider, and the inner side of the flow divider and the outer side of the air inlet duct form a flow divider channel; the air inlet cover is sleeved on the outer side of the flow divider, and the side and end sides of the air inlet cover are provided with air inlet holes.
[0006] Furthermore, a magnetic attraction member is provided at the tail end of the hair dryer body and the end of the air inlet cover, so that the air inlet cover is magnetically fixed to the tail end of the hair dryer body.
[0007] Furthermore, the air inlet duct has a conical structure, and the small end of the air inlet duct is closer to the mounting portion.
[0008] Furthermore, a plurality of the supporting parts extend from the mounting part, and a branch air duct is formed between two adjacent supporting parts.
[0009] Furthermore, a pipe forming the air duct extends from a side of the mounting portion away from the air inlet pipe, and a fan of the hair dryer is arranged in the pipe.
[0010] Furthermore, a notch connected to the air duct is provided at one end of the pipe close to the mounting portion; a cooling air duct is provided in the handheld portion of the hair dryer body, the cooling air duct is connected to the notch, and a plurality of second air inlets are provided at the bottom end of the handheld portion.
[0011] Furthermore, the end of the air inlet duct is flush with the mouth of the through hole.
[0012] The above one or more technical solutions in the hair dryer air inlet structure provided by the embodiment of the utility model have at least the following technical effects:
[0013] When the air intake structure of the hair dryer is taking in air, the airflow enters the air intake cover from the air intake holes at the sides and ends of the air intake cover, and enters the diverter cover through the air holes. After the airflow is sucked into the diverter cover, the airflow at the center of the airflow enters the air duct through the air intake duct, and the airflow with a lower air pressure entering the side of the diverter cover will be sucked into the diverter channel. The airflow diverted through the diverter channel enters the air duct through the through hole; therefore, the strong airflow and the weak airflow are diverted in an orderly manner, which can avoid the problem of airflow movement; therefore, the problem of airflow noise can be reduced, and the flow effect of the airflow can be increased. In addition, since the airflow pressure of the diverter channel is lower than the airflow pressure of the air intake duct, a certain negative pressure will be formed at the mouth of the air intake duct, so that the airflow in the diverter channel follows the airflow channel of the air intake duct, which can further avoid the phenomenon of airflow movement.

[0024] In one embodiment of the utility model hair dryer, please refer to Figures 1 to 4 The electric hair dryer has an air intake structure. Specifically, it includes a hair dryer body 100, an air duct 101 is provided inside the hair dryer body 100, and an air inlet is provided at the tail end of the air duct 101. The air intake structure includes a diverter cover 200 and an air inlet cover 300. A bracket 400 is provided at the tail end of the hair dryer body 100, and the bracket 400 includes a mounting portion 410 and an air intake duct 420. The mounting portion 410 is used to be mounted on the tail end of the hair dryer body 100, and the mounting portion 410 is provided with a through hole 411. A supporting portion 412 extends from the mounting portion 410, and the air intake duct 420 is connected to the supporting portion 412, and the outer side of the air intake duct 420 and the through hole 411 form a side air duct 413. Specifically, the supporting portion 412 is connected to the outer side of the air intake duct 420. The splitter cover 200 is sleeved on the bracket 400, and a plurality of air holes 201 are distributed on the end side of the splitter cover 200, and the inner side of the splitter cover 200 and the outer side of the air inlet duct 420 form a split channel 421. The air inlet cover 300 is sleeved on the outer side of the splitter cover 200, and the side and end sides of the air inlet cover 300 are provided with air inlet holes 301.
[0025] In this embodiment, when the hair dryer is started, the airflow enters the air inlet cover 300 from the air inlet holes 301 at the sides and ends of the air inlet cover 300, and enters the diverter cover 200 through the air holes 201. After the airflow is sucked into the diverter cover 200, the airflow at the center of the airflow enters the air duct 101 through the air inlet duct 420, and the airflow with a lower air pressure entering the side of the diverter cover 200 is sucked into the diverter channel 421. The airflow diverted through the diverter channel 421 enters the air duct 101 through the through hole 201. Therefore, the strong airflow and the weak airflow are diverted in an orderly manner, which can avoid the problem of airflow movement. The problem of airflow noise can be reduced, and the flow effect of the airflow can be increased. In addition, since the airflow pressure of the diverter channel 421 is less than the airflow pressure of the air inlet duct 420, a certain negative pressure will be formed at the mouth of the air inlet duct 420, so that the airflow in the diverter channel 421 follows the airflow flow path of the air inlet duct 420, which can further avoid the phenomenon of airflow movement.
[0026] For further information, please refer to Figure 2 , the end of the air inlet duct 420 is flush with the mouth of the through hole 411. In this embodiment, the airflow output from the air inlet duct 420 and the side air duct 413 can smoothly enter the air duct 101 from the through hole 411, avoiding interference of the end face of the mounting portion 410 with the airflow.
[0027] Furthermore, the tail end of the hair dryer body 100 and the end of the air inlet cover 300 are provided with magnetic suction parts, so that the air inlet cover 300 can be fixed to the tail end of the hair dryer body 100 by magnetic suction, which makes disassembly more convenient.
[0028] Further, refer to Figure 2 and Figure 3 The air inlet duct 420 has a conical structure, and the small end of the air inlet duct 420 is closer to the mounting portion 410. In this embodiment, when the airflow is transported in the air inlet duct 420, the airflow can be further compressed by the air inlet duct 420, thereby increasing the airflow pressure and the blowing effect.
[0029] Furthermore, a plurality of supporting portions 412 extend from the mounting portion 410, and a wind channel is formed between two adjacent supporting portions 412, so that the airflow can be further divided, and the problem of airflow swaying can be more effectively avoided.
[0030] Further, refer to Figure 2 and Figure 5 A duct 430 forming the air duct 101 extends from one side of the mounting portion 410 away from the air inlet duct 420 , and the fan 110 of the hair dryer is disposed in the duct 430 .
[0031] Further, refer to Figure 5The end of the pipe 430 near the mounting portion 410 is provided with a notch 431 connected to the air duct 101; the handle portion 120 of the hair dryer body 100 is provided with a cooling air duct 121, which is connected to the notch 431, and the bottom end of the handle portion 120 is provided with a plurality of second air inlets 122. Therefore, the airflow can also enter the cooling air duct 121 from the second air inlets 122, and then enter the air duct 101 through the notch 431, so as to dissipate heat and cool down the electronic components installed in the handle portion 120.
[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
