Description

Technical Field

[0001] This invention relates to the field of breathing air supply valve technology, specifically a pneumatically controlled vibration-reminder breathing air supply valve. Background Technology

[0002] Existing positive pressure breathing apparatus masks use an electronically controlled vibration motor to alert the wearer of low air pressure. However, if the device runs out of batteries or the battery voltage is low, the vibration function may fail, potentially causing injury or death. Therefore, it is essential to design a solution to address these issues. Summary of the Invention

[0003] The purpose of this invention is to provide a pneumatically controlled vibration-reminder breathing air supply valve, which solves the problems mentioned in the background art.

[0004] Technical solution

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pneumatically controlled vibration-reminder breathing air supply valve, comprising an air supply valve body, wherein the air supply valve body consists of a vibration plate, a vibration hammer, a vibration hammer fixing element, a pressure relief hole, a forced air supply flow regulating rod, a flow regulating handle, an air inlet, a vibration fixing block, a vibration hammer sealing port, a spring, an regulating rod, an air inlet fixing rod, and a gas delivery rod. The flow regulating handle is tightly connected to the forced air supply flow regulating rod via a bottom gear groove and is limited by a perforated stop. The flow regulating handle and the forced air supply flow regulating rod are fixed to the air supply valve body via an regulating rod and an air inlet fixing rod. The flow regulating handle is tightly connected to the flow regulating rod, and the regulating rod is movably and sealingly connected to the front end of the gas delivery rod. To adjust the forced air supply flow, rotating the flow regulating handle moves the regulating rod left and right. The size of the space between the front sealing surfaces of the regulating rod and the delivery rod controls the air intake. The regulating rod and the vibration fixing block are sealed together by a sealing ring.

[0006] The vibratory hammer is fixed to the vibratory block via a threaded connection. Inside the vibratory fixing device, the vibratory hammer is controlled by a spring to move up and down to strike the vibratory plate. When the pressure of the vibratory hammer is below 6.5 BAR, the sealing gasket at the bottom of the vibratory hammer and the joint of the vibratory fixing block form a seal, preventing the vibratory hammer from moving upward to release pressure. When the pressure of the vibratory hammer is above 7.5-50 BAR, the gas pushes the vibratory hammer upward to strike the vibratory plate, while simultaneously releasing pressure. The vibratory hammer returns to the bottom, and the vibratory plate is fixed to the vibratory fixing block by screws.

[0007] Furthermore, the sealing ring at the top of the gas delivery rod is in sealing engagement with the forced gas supply flow regulating rod.

[0008] Furthermore, the gas delivery rod is sealed to the vibration fixing block by a sealing ring on the top of the delivery rod.

[0009] Furthermore, the vibration plate is fixed to the vibration fixing block by side screws.

[0010] Furthermore, the vibratory hammer is fixed to the vibratory fixing block by external thread.

[0011] Furthermore, the bottom of the vibratory hammer has a sealing surface that seals with the sealing ring of the vibratory fixing block, and the top of the vibratory hammer is fixed by a spring, while the vibratory hammer moves up and down within the vibratory hammer fixing block.

[0012] This invention provides a pneumatically controlled vibration-activated breathing air supply valve. It has the following beneficial effects:

[0013] This pneumatically controlled vibration alert breathing air supply valve works as follows: When the inlet pressure is below 7.5 bar, air enters through the inlet and flows in the direction of the arrow to the vibrating hammer seal. Due to spring pressure, the vibrating hammer cannot move up or down. When the inlet pressure is above 7.5-50 bar, air enters through the inlet and flows in the direction of the arrow to the vibrating hammer seal. Due to the gas pressure, the vibrating hammer moves upward and strikes the vibrating plate, causing the entire air supply valve to vibrate. At the same time, the pressure relief hole releases gas, causing a decrease in pressure inside the vibrating hammer fixing device. Due to spring pressure, the vibrating hammer moves downward and seals the vibrating hammer seal. This cycle repeats continuously, solving the problem that existing positive pressure breathing protective masks use electronically controlled vibration motors to alert the wearer of low air pressure. In such cases, the device may run out of batteries or have low battery voltage, causing the vibration function to malfunction and potentially resulting in injury or death.

Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] like Figure 1As shown, this embodiment of the invention provides a pneumatically controlled vibration-reminder breathing air supply valve, including an air supply valve body. The air supply valve body consists of a vibration plate 1, a vibration hammer 2, a vibration hammer fixing 3, a pressure relief hole 4, a forced air supply flow regulating rod 5, a flow regulating handle 6, an air inlet 7, a vibration fixing block 8, a vibration hammer sealing port 9, a spring 10, an adjusting rod, an air inlet fixing rod 11, and a gas delivery rod 12. The flow regulating handle 6 is tightly connected to the forced air supply flow regulating rod 5 through a bottom gear groove and is limited by a perforated gasket. The flow regulating handle 6 and the forced air supply flow regulating rod 5 are fixed to the air supply valve body through the adjusting rod and the air inlet fixing rod 11.

[0018] The top sealing ring of the gas conveying rod 12 is sealed to the forced gas supply flow regulating rod 5. The gas conveying rod 12 is sealed to the vibration fixing block 8 through the top sealing ring of the conveying rod. The vibration plate 1 is fixed to the vibration fixing block 8 by the side screws. The vibration hammer 3 is fixed to the vibration fixing block 8 by the external thread. The bottom of the vibration hammer 2 has a sealing surface that is sealed to the sealing ring of the vibration fixing block 8. The top of the vibration hammer 2 is fixed by the spring 10. At the same time, the vibration hammer 2 moves up and down in the vibration hammer fixing 3.

[0019] Working principle: When the intake pressure is lower than 7.5 BAR, the intake air enters from the intake port 7 and flows through the vibratory hammer sealing port 9 in the direction of the arrow. Due to the pressure of the spring 10, the vibratory hammer 2 cannot move up and down.

[0020] When the intake pressure is higher than 7.5-50 bar, the intake air enters from the intake port 7 and flows in the direction of the arrow to the vibratory hammer sealing port 9. Due to the gas pressure, the vibratory hammer 2 moves upward and strikes the vibrating plate 1. The entire air supply valve vibrates, and at the same time, the pressure relief hole 4 releases air, causing the pressure inside the vibratory hammer fixing device 3 to decrease. Due to the pressure of the spring 10, the vibratory hammer 2 moves downward and seals the vibratory hammer sealing port 9. The cycle of vibration continues.

[0021] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
