Description

TECHNICAL FIELD

[0001] The utility model relates to handheld drying device technical field especially relates to a slanting air outlet type hair dryer. BACKGROUND

[0002] A kind of electric hair dryer for facilitating assembly is disclosed in Chinese patent with publication number CN215583359U, the hair dryer includes body and head, the body and head are overall L-shaped, air outlet device is built-in in the head, the end of the head is provided with air outlet for air outlet device to output airflow.

[0003] The above-mentioned electric hair dryer needs to keep the head vertical and towards the top of the head to directly blow the hair on the top of the head, so the body must be horizontal and above the head. To achieve the above conditions, the person's arm needs to be raised overall, the upper arm is lifted to the height of the shoulder, the lower arm is bent to an angle less than 90° with the upper arm and the wrist is bent to hold the body. At the same time, the position and angle of the electric hair dryer need to be constantly changed to blow the hair, which can achieve the effect of quick drying. This will cause the operation to be more laborious and the hands to be easily tired, which does not conform to ergonomics. SUMMARY

[0004] In view of the fact that using the existing electric hair dryer to directly blow the hair on the top of the head requires a large degree of arm raising and bending of the joints, which leads to laborious use, the purpose of the utility model is to provide a slanting air outlet type hair dryer that can directly blow the hair on the top of the head without a large degree of arm raising.

[0005] To solve the above technical problems, the utility model solves them through the following technical solutions:

[0006] A slanting air outlet type hair dryer includes a body and a head, an air outlet structure is formed on the head, an air outlet device is built-in in the body, the head is inclined and extended upwards at the end of the body and the included angle between the head and the body is obtuse, and the air outlet structure is located on the side wall of the head and the opening faces the side where the included angle between the head and the body is formed.

[0007] With the above scheme, when the hair dryer in the present scheme is used, the head only needs to be kept horizontal above the head and the included angle between the head and the body needs to face the top of the head, so the air outlet on the side wall of the head can directly blow the hair on the top of the head. At this time, the body is vertical, when holding the body, the upper arm part of the arm does not need to be raised greatly, only the lower arm needs to be kept vertical and lifted upwards, so the wrist part can be above the top of the head. Therefore, the hair dryer in the present scheme is more labor-saving and less likely to cause hand fatigue, which is more in line with ergonomics.

[0008] As a preferred, the included angle between the head and the body is any angle within the range of 120° to 140°.

[0009] The scheme further limits the range of the angle between the head and the body, and has the advantages that the head blowing is more in line with the head shape during hair blowing and drying, the wrist and the lower arm can be kept in a comfortable posture when the user holds the body, the operation is in line with ergonomics, comfortable and easy, and the scheme is a humanized design.

[0010] Preferably, the head comprises a shell assembly and an inner shell assembly arranged inside the shell assembly, and the air outlet structure comprises a first air outlet formed on the shell assembly and a second air outlet formed on the inner shell assembly and connected to the first air outlet.

[0011] Preferably, a heat insulation cavity is formed between the shell assembly and the inner shell assembly, and a heat dissipation structure is arranged for accelerating the cooling of the heat insulation cavity, the heat dissipation structure comprises a first heat dissipation hole formed on the shell assembly near the first air outlet and a second heat dissipation hole formed on the side wall of the shell assembly except the side wall provided with the first heat dissipation hole.

[0012] The air flow of the air outlet device causes the inner shell assembly to heat up rapidly, the heat insulation cavity effectively prevents the heat transfer from the inner shell assembly to the shell assembly by taking advantage of the poor heat conduction of air, the heat dissipation structure enables the air in the heat insulation cavity to exchange with the air outside, and the heat dissipation structure can also accelerate the air exchange when the hair drying device is working, when the hair drying device blows air outward, the air flow rate near the first heat dissipation hole is much lower than the air flow rate near the first air outlet, which causes the air pressure near the first heat dissipation hole to decrease, generating a certain suction force, so that the air in the heat insulation cavity flows out from the first air permeable hole at a higher speed, and the air outside can flow into the heat insulation cavity from the second air permeable hole, thereby circulating and flowing to accelerate heat dissipation.

[0013] Preferably, the first air outlet and the second air outlet are long strips and extend along the head, and the first air outlet and the second air outlet are respectively provided with at least two groups of air outlets.

[0014] The shape and arrangement of the air outlets in the scheme can maximize the area of the air outlet structure and increase the air output of the hair drying device.

[0015] Preferably, the inner shell assembly comprises a pair of inner shell components connected to each other and connected to the body, and a flow distribution component arranged between the two inner shell components and used for uniformly distributing the air flow output by the air outlet device, the flow distribution component comprises a plurality of arc-shaped flow distribution blades, the flow distribution blades are arranged in the second air outlet in a one-to-one correspondence, and the overall length of the flow distribution blades increases from the side of the air outlet structure close to the body to the side of the air outlet structure away from the body.

[0016] Preferably, the side of the flow distribution blade close to the second air outlet extends a protruding rib with an end flush with or protruding from the second air outlet.

[0017] By the above scheme, the arrangement of the shunt vanes in the scheme reduces the airflow blocked by the shunt vanes close to the air outlet device as much as possible, and makes the airflow received by each shunt vane as uniform as possible, so that the air outlet amount at each part of the air outlet is more uniform.

[0018] In the scheme, the purpose of arranging multiple groups of shunt vanes is to divide the air outlet into multiple regions for air outlet, and the protrusions, as extensions of the shunt vanes, have the same effect as tracks. The airflow flowing through the protrusions from the shunt vanes enhances the directionality of the flow, so that the airflow in each region can form an air column independently. Such an air column has a certain impact force and can have a certain massage effect when blowing the head, thereby relaxing the head.

[0019] As a preferred embodiment, the shunt component further comprises a splicing frame fixedly spliced with the two inner shell components, the shunt vanes are integrally formed on the splicing frame, and the inner shell components and the shunt component are provided with a splicing structure for forming a second air outlet after splicing.

[0020] As a preferred embodiment, when the number of the second air outlets is two, the splicing structure comprises a first notch formed on the inner shell component and a second notch formed on the two sides of the splicing frame and matched with the first notch to form the second air outlet when the shunt component is spliced with the inner shell component.

[0021] By the above scheme, the inner shell component is usually made of a metal sheet by die casting. Designing too many structures in the inner cavity will increase the design difficulty of the die casting mold and the difficulty of demolding. In the scheme, the shunt component is designed as an independent component and spliced in the inner shell assembly during assembly, so it does not need to be designed as part of the inner shell component. This can simplify the design complexity and also reduce the production difficulty.

[0022] As a preferred embodiment, the handpiece further comprises a noise reduction structure for reducing the working noise of the hair dryer. The noise reduction structure comprises a flange protruding from the edges of the first notch and the second notch. The outer shell assembly is recessed to form a groove at the first air outlet. When the first notch and the second notch are matched, the flange can be inserted into the groove to form abutment, and the flange and the groove are tightly matched.

[0023] By the above scheme, since the inner shell component and the shunt component are independent components, the second air outlet is formed by the three components. When the hair dryer is working, the airflow impacting the second air outlet causes the inner shell component and the shunt component to vibrate and collide with each other, thereby generating noise. In the scheme, the flange can be inserted into the groove and tightly matched with it. As part of the inner shell component or the shunt component, when the flange is limited in movement, it is difficult for the airflow impacting the inner shell assembly to cause it to vibrate, thereby improving the defect that the noise is large due to the collision between the inner shell assemblies.

[0024] The hair drying device in the scheme is easy to use and less likely to cause hand fatigue, and is more in line with ergonomics. BRIEF DESCRIPTION OF DRAWINGS

[0047] Embodiment 2

[0048] Based on the basis of embodiment 1, this embodiment further limits a slant air outlet type hair dryer.

[0049] According to Figure 4 , in this embodiment, the shell assembly includes a pair of mutually buckling shell parts 3, one of the shell parts 3 is provided with a first air outlet 4, the shell parts 3 are fixed through a clamping structure, according to Figure 5 , 15 The clamping structure includes clamping grooves 301 and buckles 302 respectively arranged on the shell parts 3 and capable of corresponding clamping one by one, and first protrusions 303 and first insertion grooves 304 respectively formed on the edges of the shell parts 3, when the shell parts 3 are spliced, the clamping grooves 301 and the buckles 302 are buckled, the first protrusions 303 are inserted into the first insertion grooves 304, the buckles 302 and the clamping grooves 301 ensure the connection of the shell parts 3, and the first insertion grooves 304 and the first protrusions 303 cooperate with each other to limit the movement between the two shell parts 3, thereby increasing the stability of the cooperation.

[0050] According to Figure 15 , a heat insulation cavity 6 is formed between the shell assembly and the inner shell assembly, and a heat dissipation structure for accelerating the cooling of the heat insulation cavity 6 is arranged on the shell assembly and the inner shell assembly, according to Figure 1 , 4As shown in Figure 15, the heat dissipation structure includes a first heat dissipation hole 7 opened on the outer shell assembly near the first air outlet 4. In this embodiment, since the first air outlet 4 is elongated, several first heat dissipation holes 7 are distributed at intervals along the direction in which the first air outlet 4 is opened. In addition to the side wall on which the first heat dissipation hole 7 is provided, a second heat dissipation hole 8 is opened on both sides of the outer shell assembly.
