A buffer structure for uniform air intake

Abstract

This utility model relates to a buffer structure for uniform air intake, comprising a cap-shaped outer layer (101), an airbag membrane (102) disposed inside the outer layer (101) and sealed therewith to form an air intake chamber, the outer layer (101) having at least one air inlet (102) for inflating the air chamber, the air intake chamber also having a buffer layer (104) separating the outer layer (101) and the airbag membrane (102), the buffer layer (104) and the outer layer (101) forming a buffer cavity (105), and the buffer layer (104) having multiple air outlets (1041). This device dilutes the direct airflow through the buffer layer, reducing the airflow velocity and pressure at the air outlets by several times. For the elastomer, the multi-point load difference is very small, thus making the elastomer deformation uniform.

Description

Technical Field

[0001] This utility model relates to a buffer structure, and more specifically to a buffer structure for uniform air intake. Background Technology

[0002] The air bladder in the hair growth cap has two main functions:

[0003] The airbag, when inflated, automatically adjusts its fit to the user's head shape, filling the gaps between the cap and the scalp and ensuring that the laser or care module adheres tightly to the scalp, thereby enhancing the treatment effect.

[0004] For comfort and slip resistance, the inside of the airbag is usually lined with silicone particles, which not only prevents slipping but also avoids the pressure and stuffiness of traditional headbands, thus improving wearing comfort.

[0005] like Figure 1 As shown, this is a common hair growth cap in the field. The hair growth cap includes an outer layer 101 and an air bladder membrane 102. The air bladder membrane 102 is disposed on the inner wall of the outer layer 101. The inner wall of the outer layer 101 and the air bladder membrane 102 form an inflation chamber. Air inlets 103 are provided on the left and right sides of the outer layer 101. In actual use, gas enters the inflation chamber through the air inlets 103. However, when using an automatic inflation device, the airflow velocity at the air inlet 103 is relatively fast, and the pressure on the air bladder membrane 102 directly opposite the air inlet 103 is relatively concentrated. This results in uneven deformation pressure on the elastic body of the air bladder membrane 102. The area with higher pressure directly opposite the air inlet 103 deforms first, causing uneven deformation of the air bladder membrane 102, which in turn affects its service life. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a buffer structure for uniform air intake in a hair growth cap.

[0007] The technical solution of this utility model is as follows:

[0008] A buffer structure for uniform air intake includes a cap-shaped outer layer (101), an airbag membrane (102) disposed inside the outer layer (101) and sealed thereto to form an air intake chamber, wherein the outer layer (101) has at least one air inlet (102) for inflating the air chamber, characterized in that:

[0009] The air intake chamber is also provided with a buffer layer (104) that separates the outer layer (101) and the airbag membrane (102). The buffer layer (104) and the outer layer (101) form a buffer cavity (105). The buffer layer (104) is provided with a plurality of air outlets (1041).

[0010] Furthermore, the air inlet (102) is located on the bottom outer side of the outer layer (101).

[0011] Furthermore, there are two air inlets (102), which are symmetrically arranged on both sides of the bottom of the outer layer (101).

[0012] Furthermore, the air outlet (1041) is located on the buffer layer (104) at a position away from the buffer layer (104) and directly opposite the air inlet (102).

[0013] Furthermore, the bottom of the outer layer (101) is provided with an extension edge, and the bottom of the airbag membrane (102) is attached to the extension edge.

[0014] Furthermore, the connection between the buffer layer (104) and the outer layer (101) is located at the lower part of the air inlet (102).

[0015] Furthermore, the air vents (1041) are arranged in a square and circular array on the buffer layer (104).

[0016] By means of the above solution, this utility model has at least the following advantages:

[0017] The buffer layer dilutes the direct airflow, reducing the airflow velocity and pressure at the outlet by several times. For the elastomer, the multi-point load difference is very small, thus making the elastomer variation uniform.

[0018] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0024] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0025] See Figure 2 A preferred embodiment of the present invention describes a buffer structure for uniform air intake, comprising an outer layer 101 in the shape of a hat. The outer layer 101 is typically made of metal or plastic and is shaped like a hat, primarily for headwearing, to provide support.

[0026] An airbag membrane 102 is disposed inside the outer layer 101 and sealed to form an air intake chamber. The airbag membrane 102 is made of elastic material and can form an airbag after inflation, providing elastic support. Typically, the airbag membrane 102 can be made of elastic rubber or thermoplastic polyurethane.

[0027] The outer layer 101 is provided with at least one air inlet 102 for inflating the air chamber. The air inlet chamber is also provided with a buffer layer 104 that separates the outer layer 101 and the air bladder membrane 102. The buffer layer 104 and the outer layer 101 form a buffer cavity 105. The buffer layer 104 is provided with multiple air outlets 1041.

[0028] The air inlet 102 is located on the bottom outer side of the outer layer 101. The air inlet 102 extends into a cylindrical hole from the outside of the outer layer 101, and a valve core is generally installed inside the air inlet. The number of air inlets 102 can be set to two, symmetrically arranged on both sides of the bottom of the outer layer 101. This can speed up the inflation process.

[0029] The vent 1041 is located on the buffer layer 104, away from the buffer layer 104 and directly opposite the inlet 102, in order to prevent gas from directly entering the airbag membrane 102.

[0030] The bottom of the outer layer 101 is provided with an extension edge, and the bottom of the airbag membrane 102 is attached to the extension edge, so that the airbag membrane 102 can be fixed to the outer layer 101.

[0031] The connection between the buffer layer 104 and the outer layer 101 is located at the lower part of the air inlet 102, so that the gas can enter the buffer layer 104 better.

[0032] The air outlets 1041 are arranged in a square or circular array on the buffer layer 104. The array density can be adjusted according to the pressure gradient required in different areas to achieve zoned pressure equalization.

[0033] The advantages of this utility model are as follows:

[0034] This utility model's double-layer chamber structure achieves the technical effect of first buffering and then equalizing pressure, preventing airflow from directly acting on the airbag membrane and improving inflation stability;

[0035] Multiple evenly spaced air vents ensure pressure balance in different areas of the airbag membrane, resulting in uniform elastomer deformation and better fit to the user's head.

[0036] The symmetrical air intake on both sides can balance the pressure on the left and right sides of the cap and prevent it from tilting.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
