A breathing mask with an electrically powered air supply mechanism

Abstract

This invention relates to the field of respiratory mask technology, and in particular to a respiratory mask with an electrically powered air delivery mechanism. The mask includes a mask body and an external connecting cover installed at the air inlet at the front end of the mask body. An external connecting cover for connecting an external oxygen tank is snapped onto the outer opening of the external connecting cover. This respiratory mask with an electrically powered air delivery mechanism, through a lateral pressure-boosting cover with an integrated structure on one side of the external connecting cover, not only increases the delivery pressure of the oxygen tank but also reduces oxygen tank consumption. When worn alone, an electrically controlled booster fan inside the lateral pressure-boosting cover pressurizes and guides external air into the external connecting cover, greatly reducing the wearer's breathing difficulty and fatigue. A detachable external filter cover is threaded onto the outer opening of the lateral pressure-boosting cover, allowing for increased filtration through layering, making it adaptable to various working environments.

Description

Technical Field

[0001] This invention relates to the field of respiratory mask technology, and in particular to a respiratory mask equipped with an electric air delivery mechanism. Background Technology

[0002] A breathing mask is a protective device that protects the human respiratory system. In environments with high dust concentrations, it can prevent the wearer from inhaling harmful particles, thus preventing pneumoconiosis. It is suitable for various dusty workplaces.

[0003] Traditional breathing masks consist of a mask, a flexible air hose, and an oxygen tank. However, prolonged use of the oxygen tank not only increases the difficulty of operation for users but also significantly increases operating costs. Furthermore, relying solely on the wearer's own breathing without the oxygen tank also increases breathing difficulty and fatigue. Therefore, some breathing masks on the market are equipped with built-in fans. However, these masks have a simple structure, a single control method, and a fixed external filter that cannot be quickly added or removed as needed, resulting in limited applicability and high maintenance costs. Summary of the Invention

[0004] The technical problem that this invention aims to solve is that commercially available breathing masks have simple structures, single control methods, and fixed external filter devices that cannot be quickly added or removed as needed, resulting in a limited range of applications and high maintenance costs.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a breathing mask with an electric air supply mechanism, including a mask body and an external connecting cover installed at the air inlet position at the front end of the mask body. An external connecting cover for connecting an external oxygen tank is snapped into the outer opening of the external connecting cover. The mask body has an integrally structured lateral pressure boosting cover on one side of the external connecting cover. An electrically controlled pressure boosting fan is installed inside the lateral pressure boosting cover. A detachable external filter cover is threaded into the outer opening of the lateral pressure boosting cover. A lateral linkage closing cover is elastically fitted inside the external connecting cover at the inner communication port of the lateral pressure boosting cover. An internal guide nozzle for controlling the lateral linkage closing cover is provided on the inner connecting surface of the external connecting cover.

[0006] The outer opening of the external connecting cover has an external assembly frame for fixing the external connecting cover. The external assembly frame has lateral slots on both sides that cooperate with the external connecting cover. The external connecting cover is fixedly assembled with the external assembly frame by inserting the elastic buckles on both sides of the connecting surface into the lateral slots.

[0007] The outer wall of the external connecting cover is provided with a lateral communication port that cooperates with the lateral linkage closing cover plate and the internal guide nozzle.

[0008] The outer air inlet of the side booster cover has an outwardly protruding integral external threaded assembly frame. The detachable external filter cover is threaded and fixed to the outside of the external threaded assembly frame through an internal threaded through hole on the assembly surface.

[0009] The detachable external filter cover has an external air inlet with a metal filter screen inside on its outer side, and the outer side of the detachable external filter cover has an outwardly protruding external threaded expansion frame around the external air inlet.

[0010] An internal push-button switch for controlling the electronically controlled booster fan is installed on the inner side of the external connection cover, located on the side of the lateral communication port.

[0011] Both sides of the lateral linkage closing cover plate have external closing protrusions to improve the lateral closing sealing performance.

[0012] An air flow sensor is fixedly installed on the inner side of the inner connecting port.

[0013] A flip-type external adjustment frame is movably mounted on the outer side of the lateral pressure shroud.

[0014] An embedded LED lighting module is fixedly installed on the outer surface of the flip-type external adjustment frame.

[0015] The beneficial effects of this invention are:

[0016] (1) A breathing mask with an electric air supply mechanism of the present invention can not only increase the delivery pressure of the oxygen tank by having an integral structure of the lateral pressure booster on one side of the external connecting cover, but also reduce the consumption of the oxygen tank.

[0017] (2) When worn alone, the electric-controlled booster fan inside the side booster can pressurize and guide the outside air into the inside of the external connection cover, greatly reducing the wearer's breathing difficulty and reducing fatigue.

[0018] (3) By threading a detachable external filter cover at the opening on the outside of the side pressure hood, the filtration effect can be increased by stacking, making it suitable for various working environments.

[0019] (4) A lateral linkage closing cover is elastically assembled inside the external connecting cover. When the external connecting cover is installed on the external connecting cover, the lateral linkage closing cover can be quickly controlled, making the operation very convenient.

[0020] (5) The entire device not only has electric air supply, but also has the power supply for flip lighting, greatly improving the functional integration. Attached Figure Description

[0024] Figure 3 This is a schematic diagram of the internal structure of the external connecting cover in the connected state of the present invention. Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0026] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] Figure 1 , Figure 2 and Figure 3 The breathing mask shown includes a mask body 1 and an external connecting cover 2 installed at the air inlet position at the front end of the mask body 1. An external connecting cover 3 for connecting an external oxygen tank is snapped onto the outer opening of the external connecting cover 2. The mask body 1 has an integrally structured lateral pressure cover 4 on one side of the external connecting cover 2. An electrically controlled pressure fan 5 is installed inside the lateral pressure cover 4. A detachable external filter cover 41 is threaded onto the outer opening of the lateral pressure cover 4. A lateral linkage closing cover 6 is elastically fitted onto the inner connecting port of the lateral pressure cover 4 inside the external connecting cover 2. An internal guide nozzle 7 for controlling the lateral linkage closing cover 6 is provided on the inner connecting surface of the external connecting cover 3.

[0028] Working principle: Mode 1: The oxygen tank's air duct is connected to the external connecting cover 3, and then the oxygen in the oxygen tank is introduced into the mask body 1 through the external connecting cover 2; Mode 2: The oxygen tank's air duct is connected to the external connecting cover 3, and then the oxygen in the oxygen tank is introduced into the mask body 1 through the external connecting cover 2. At the same time, the electrically controlled booster fan 5, through high-speed rotation, replenishes the external connecting cover 2 with external air, thereby reducing the consumption of oxygen tank; Mode 3: The external connecting cover 3 is separated, and the external air is completely introduced into the external connecting cover 2 through the high-speed rotation of the electrically controlled booster fan 5.

[0029] To facilitate external installation and disassembly, the outer opening of the external connecting cover 2 has an external assembly frame for fixing the external connecting cover 3. The external assembly frame has lateral slots on both sides that cooperate with the external connecting cover 3. The external connecting cover 3 is fixedly assembled with the external assembly frame by inserting the elastic buckles 8 on both sides of the connecting surface into the lateral slots.

[0030] When disassembly is required, simply press the elastic buckle 8 located in the side latch with your hand, and the external connecting cover 3 will separate from the external connecting cover 2.

[0031] To facilitate lateral communication, the outer wall of the outer connecting cover 2 is provided with a lateral communication port that cooperates with the lateral linkage closing cover plate 6 and the internal guide nozzle 7.

[0032] To accommodate the external threaded assembly, the outer periphery of the air inlet of the side booster shroud 4 has an outwardly protruding integrated external threaded assembly frame 9. The detachable external filter shroud 41 is threaded and fixed to the outside of the external threaded assembly frame 9 through the internal threaded through hole on the assembly surface.

[0033] To accommodate external expansion and allow for the free addition or reduction of filtration methods and layers, an external air inlet with a metal filter screen 10 inside is opened on the outer side of the detachable external filter cover 41. The outer side of the detachable external filter cover 41 has an outwardly protruding external threaded expansion frame 11 located around the external air inlet.

[0034] An air filter element is installed on the removable external filter cover 41. The filter element can be a PP cotton filter element or an activated carbon filter element.

[0035] To facilitate automatic control, an internal push-button switch 12 for controlling the electronically controlled booster fan 5 is installed on the inner side of the external connection cover 2, located on the side of the lateral connection port.

[0036] When the pressurization mode is activated, once the outer connecting cover 2 is separated from the external connecting cover 3, the lateral linkage closing cover 6 will flip to the inner opening of the lateral communication port, and then the inner pressing switch 12 will be squeezed, which will activate the electronically controlled pressurization fan 5 to pressurize the inside of the mask.

[0037] To improve the closing effect, the lateral linkage closing cover plate 6 has external closing protrusions 13 on both sides to improve the lateral closing seal.

[0038] An electromagnetic valve is installed inside the external closed protrusion 13. In pressurization mode, once the pressure inside the oxygen tank decreases, or when people activate the low-energy mode via an external switch, the electromagnetic valve and the electrically controlled pressurization fan 5 will be activated to draw outside air into the interior, which will then supply air into the mask in conjunction with the oxygen tank, thereby reducing oxygen consumption.

[0039] To facilitate monitoring of the filtration effect, an air flow sensor 14 is fixedly installed on the inner side of the inner connecting port.

[0040] The air flow sensor 14 senses the air pressure inside the inner connection port. The flow rate of the filter element is determined based on the pressure change. The effect of the filter element is determined based on the change in flow rate. When the flow rate is less than the set minimum flow rate, it means that too many impurities have accumulated inside the filter element and the filter element needs to be replaced.

[0041] To facilitate external assembly and adjustment, a flip-type external adjustment frame 15 is movably mounted on the outer side of the side pressure shroud 4.

[0042] The flip-type external adjustment frame 15 is movably assembled with the outside of the side pressure cover 4 via a rotating shaft on the assembly end.

[0043] To complement the lighting, an embedded LED lighting module 16 is fixedly mounted on the outer surface of the flip-type external adjustment frame 15.

[0044] The lighting range can be controlled by manually adjusting the angle of the embedded LED lighting module 16 by flipping the external adjustment frame 15.

[0045] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
