Description

Technical Field

[0001] This invention relates to the field of respirator mask connector technology, and in particular to an anti-dislodgement T-type air supply valve for oxygen respiration. Background Technology

[0002] Positive pressure oxygen respirator masks protect firefighters and rescue workers from inhaling harmful toxic gases, fumes, and airborne pollutants during firefighting or rescue operations. They can also be used in oxygen-deficient environments to prevent the inhalation of toxic gases, thus enabling effective firefighting, rescue, and relief work.

[0003] The T-type air supply valve is a standard accessory for positive pressure oxygen respirators and masks, used to supply air from the air delivery tube into the mask. Typically, the air supply valve is a replaceable accessory and needs to be easily attachable and detachable from the mask.

[0004] However, in practical applications, it has been found that the T-type air supply valve is prone to detachment due to its large size and factors such as vigorous movement or collisions of personnel. Therefore, how to improve the anti-detachment structure of the T-type air supply valve has become a research topic. Utility Model Content

[0005] This invention provides an anti-detachment T-type air supply valve for oxygen respiration, which improves the anti-detachment structure of the T-type air supply valve and reduces the possibility of the T-type air supply valve falling off during operation.

[0006] To achieve the above objectives, the embodiments of this invention adopt the following technical solutions:

[0007] A T-type air supply valve for oxygen respiration, comprising a T-type air supply valve through part (2) and a T-type air supply valve interface (1) installed in the middle of the T-type air supply valve through part (2), wherein the T-type air supply valve is connected to a mask (3) through the T-type air supply valve interface (1).

[0008] The T-type air supply valve interface (1) is provided with a T-type air supply valve interface rotating platform (1-1) and a T-type air supply valve interface fixing hole (1-2) on its periphery.

[0009] A pin (2-2) for the T-type air supply valve is provided at a position corresponding to the fixing hole (1-2) of the T-type air supply valve interface on the straight part (2) of the T-type air supply valve.

[0010] If the anti-detachment structure is closed, the T-type air supply valve interface rotary table (1-1) rotates to the right until the pin (2-2) of the T-type air supply valve straight section is inserted into the T-type air supply valve interface fixing hole (1-2); the elastic component (2-4) of the T-type air supply valve straight section is in the relaxed state.

[0011] If the anti-detachment structure is opened, push the pin toggle key (2-3) of the T-type air supply valve straight section outward and compress the elastic component (2-4) of the T-type air supply valve straight section; rotate the T-type air supply valve interface rotary table (1-1) to the left until it is limited by the T-type air supply valve straight section stop (2-1).

[0012] Both sides of the T-type air supply valve direct passage (2) are connected to the air supply device. During inhalation, gas is supplied from both sides of the T-type air supply valve direct passage (2) by a one-way valve. The gas movement direction includes: during inhalation, gas enters the mask (3) from the left side of the T-type air supply valve direct passage (2), and during exhalation, gas exits from the right side of the mask (3).

[0013] The T-type air supply valve for oxygen respiration provided in this new embodiment, in practical application, utilizes the improved anti-detachment structure of this embodiment. The T-type air supply valve interface (1) in the open state is inserted into the mask, and the T-type air supply valve interface rotating platform (1-1) is rotated to the right so that the pin (2-2) of the straight part of the T-type air supply valve is inserted into the fixing hole (1-2) of the T-type air supply valve interface. At this time, the T-type air supply valve interface rotating platform (1-1) cannot move. In this way, the T-type air supply valve will not fall off the mask due to external force collision, squeezing, etc., thus achieving the anti-detachment effect. Attached Figure Description

[0025] This embodiment designs a method such as Figure 1-10The anti-detachment T-type air supply valve shown comprises a T-type air supply valve through part (2) and a T-type air supply valve interface (1) installed in the middle of the T-type air supply valve through part (2). The anti-detachment T-type air supply valve is connected to the mask (3) through the T-type air supply valve interface (1). The T-type air supply valve interface (1) is provided with a T-type air supply valve interface rotating platform (1-1) and a T-type air supply valve interface fixing hole (1-2) on its periphery. A T-type air supply valve through part pin (2-2) is provided at the position corresponding to the T-type air supply valve interface fixing hole (1-2) on the T-type air supply valve through part (2).

[0026] The methods for closing the anti-detachment T-type air supply valve include: […]. Figure 1 The T-type air supply valve interface rotary table (1-1) rotates to the right, causing the T-type air supply valve straight-through pin (2-2) to insert into the T-type air supply valve interface fixing hole (1-2). At this time, the T-type air supply valve interface rotary table (1-1) cannot move. Figures 3-4 As shown, the T-type air supply valve is in the closed state, and the elastic component (2-4) of the straight-through part of the T-type air supply valve is in the relaxed state;

[0027] The method of opening the anti-detachment T-type air supply valve includes: Figure 3 When the pin toggle key (2-3) of the straight section of the T-type air supply valve is moved outward, the elastic component (2-4) of the straight section of the T-type air supply valve is in a compressed state. At the same time, the rotating table (1-1) of the T-type air supply valve interface is rotated to the left and is fixed by the stop (2-1) of the straight section of the T-type air supply valve. At this time, the pin (2-2) of the straight section of the T-type air supply valve is limited by the T-type air supply valve interface (1).

[0028] Under normal circumstances, the T-type air supply valve is in a state of readiness when it is not installed on the mask. Figure 1 Open state, such as Figure 8 -Figure 9 Therefore, the steps to install the T-type air supply valve in the open state onto the mask are: first insert the T-type air supply valve interface (1) in the open state into the mask, and then perform the air supply valve closing step. In this way, the T-type air supply valve will not fall off the mask due to external force collision, squeezing, etc., thus achieving the anti-fall-off effect.

[0029] The left and right sides of the T-type air supply valve direct passage (2) are connected to the air supply device. The direction of gas movement is as follows: when inhaling, the gas enters the mask from the left side, and when exhaling, the gas exits from the mask from the right side. The gas can only enter from the left side and exit from the right side. One one-way valve is installed on each side to ensure that the gas can only enter from the left side and exit from the right side.

[0030] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to mutually. Each embodiment focuses on its differences from other embodiments. In particular, the device embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments. The above descriptions are merely specific embodiments of this invention, but the scope of protection of this invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this invention should be included within the scope of protection of this invention. Therefore, the scope of protection of this invention should be determined by the scope of the claims.
