Description

Airbag control device

[0001] The present invention relates to a pressure regulating structure, and more particularly to an airbag control device for controlling different states of an airbag to be inflated, maintained in a current state, or exhausted.

Background technique

[0002] There is an air bed for the patient to stay in bed for a long time, to prevent the skin from being acne due to long-term compression. The air bed is inflated by an air pump. After the airbed is lying on the patient, the pressure is different according to the patient's body shape, body weight, and the corresponding pressure of the air bed corresponding to each part of the human body, so the air bed is mostly designed to be juxtaposed by a plurality of independent airbag strips. Therefore, each airbag strip can adjust the internal air pressure to an appropriate state according to different needs. The pressure regulating structure of the existing airbag is mostly disposed in the covering structure of the air bed, and the pressure regulating 吋 is quite troublesome, and the entire covering structure needs to be smashed, and the pressure regulating structure has only two functions of air flow passage or open circuit, when the airbag interior Excessive pressure, or the need for CPR emergency sputum, does not have a pressure relief function, resulting in the actual use of the air bed has many limitations and shortcomings.

technical problem

[0007] The inner body has a long hollow shape, and the inner body is sequentially provided with a first opening and a second opening, and the first opening and the second opening are on the same axis And a third port and a fourth port are disposed at another corresponding surface of the inner body, and the third port is located on the same axis as the fourth port, wherein the The second cornice is located on the same section as the third cornice, and the second cornice is in a penetrating relationship with the third cornice.

[0008] After the inner body group is placed at the space of the outer casing, the first port and the first pipe are in the same cross-sectional relationship; and the second port and the third port are The second pipe body has a relationship on the same section line; and the fourth port is in a relationship with the exhaust port on the same section line.

[0009] The first pipe body is connected to the air pump, and the second pipe body is used for connecting with the air bag.

[0010] The outermost end of the inner body is provided with a knob; and the first, second, third and fourth ports are respectively provided with a mouthwash oil seal, and the inner body is A spacer oil seal is respectively disposed on the sides of the first, second and fourth ports.

[0011] After the inner body is placed in the space, a cover is disposed at the outer edge of the inner body.

Advantageous effects of the invention

Beneficial effect

[0012] The utility model can be used for controlling different states of the airbag to change in inflation, maintaining the status quo or exhausting, so that the pressure inside the airbag is insufficient, the air pressure can be supplemented, the pressure inside the airbag is too large, or CPR is required. After the first aid, the air can be drained. When the pressure inside the airbag is appropriate or the air bed needs to be moved, it can be stopped to maintain the status quo; thereby achieving the practical purpose of multi-function.

BEST MODE FOR CARRYING OUT THE INVENTION

[0036] The structure and the efficacies of the airbag control device of the present invention will be described in detail with reference to the accompanying drawings.

[0037] Referring to FIG. 1 and FIG. 2, the airbag control device of the present invention mainly includes an outer casing 1 and an inner body 2, and the inner body 2 is received in the outer casing 1 and can be rotated. The outer casing 1 is disposed between the air pump and the air bag (not shown). The outer casing 1 has a long cylindrical shape, and an inner end surface thereof is a hollow space 10, and the outer casing body 1 is sequentially provided with a first pipe body 11, a second pipe body 12 and an exhaust port 13, The The first pipe body 11 and the second pipe body 12 are located on the same axis line as the exhaust port 13. The inner body 2 has a hollow shape, and the inner body 2 is sequentially provided with a first opening 21 and a second opening 22, and the first opening 21 and the second opening 22 are located at the same axis. On the line, a third port 23 and a fourth port 24 are further disposed at another corresponding surface of the inner body 2, and the third port 23 and the fourth port 24 are located on the same axis line. The second port 22 is in the same cross section as the third port 23, and the second port 22 is in a through relationship with the third port 23; when the inner body 2 is placed in the outer casing After the space 10 of the body 1, the first port 2 1 and the first tube 11 are in the same cross-sectional relationship; and the second port 22, the third port 23 and the second tube 12 is a relationship in the same hatching; the fourth port 24 and the exhaust port 13 are in the same hatching relationship. The first tube 11 is for connecting with an air pump, and the second tube 12 is for connecting with the air bag. The outermost end of the inner body 2 is provided with a knob 20; and the first port 21, the second port 22, the third port 23 and the fourth port 24 are respectively provided with a mouthpiece oil seal 211, 221, 231, 241, to ensure airtightness; and the inner body 2 is respectively provided with a spacer oil seal 25 on the side edges of the first port 21, the second port 22 and the fourth port 24 to ensure airtightness . Moreover, after the inner body 2 is placed in the space 10, a cover 14 is disposed at the outer edge of the inner body 2.

[0038] When the utility model is to perform an inflation procedure, that is, air is required to enter the airbag 由 by the air pump, and the knob 20 is rotated, as shown in FIG. 3, the first port 21 and the first pipe body 11 are overlapped and connected to each other. And the second port 22 overlaps and communicates with the second pipe body 12, and then the air enters the first pipe body 11 by the air pump, flows through the first port 21 into the inner body 2, and then The second port 22 is pierced and flows out through the second tube 12 into the air bag, that is, the inflation operation is completed.
