Description

Technical Field

[0001] The present invention relates to the technical field of breathing masks, in particular to a breathing mask with an electric air supply mechanism. Background Art

[0002] A breathing mask is a protective equipment that protects the safety of the human respiratory system. In an environment with high dust concentration, it can prevent the wearer from inhaling harmful particles and prevent pneumoconiosis. It is suitable for a variety of dusty workplaces.

[0003] Traditional breathing masks are composed of masks, air guide hoses and oxygen tanks. However, long-term use of oxygen tanks will not only increase the difficulty of operation for users, but also greatly increase the cost of use. Traditional breathing masks are separated from oxygen tanks and rely entirely on human breathing, which will also increase the breathing difficulty of the wearer and lead to increased fatigue. Therefore, there are some breathing masks with blowers on the market, but the structure of such breathing masks is simple, the control method is single, and the external filter device is fixed and cannot be quickly increased or decreased as needed, resulting in a limited scope of application and high subsequent maintenance costs. Summary of the invention

[0004] The technical problem to be solved by the present invention is that the respiratory masks on the market have a simple structure, a single control method, and a fixed external filter device that cannot be quickly increased or decreased according to needs, resulting in a relatively limited scope of application and relatively high subsequent maintenance costs.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a breathing mask with an electric air supply mechanism, comprising a mask body and an external connecting cover installed at the air inlet position at the front end of the mask body, the outer opening position of the external connecting cover is clamped with an external connecting cover shell for an external oxygen tank, the outside of the mask body is located on one side of the external connecting cover and has an integrated side booster cover, the inside of the side booster cover is installed with an electric-controlled booster fan, the outer opening position of the side booster cover is threadedly equipped with a detachable external filter cover, the inside of the external connecting cover is elastically equipped with a side linkage closing cover plate at the inner connecting port position of the side booster cover, and the inner connecting surface of the external connecting cover shell is provided with an internal guide nozzle for controlling the side linkage closing cover plate.

[0006] The outer opening of the external connection cover has an external assembly frame for fixing the external connection cover shell. Side snap-ons matching the external connection cover shell are opened on both sides of the external assembly frame. The external connection cover shell is inserted into the side snap-ons through elastic buckles on both sides of the connection surface and fixedly assembled with the external assembly frame.

[0007] A lateral communication opening matched with the lateral linkage closing cover plate and the internal flow guide nozzle is provided on the outer wall of the external connection cover.

[0008] The outer periphery of the air inlet of the lateral boost cover is provided with an external thread assembly frame of an integral structure protruding outwards, and the detachable external filter cover is sleeved on the outer side of the external thread assembly frame through the internal thread through hole on the assembly surface and is threadedly fixed to the lateral boost cover.

[0009] The outer side surface of the detachable external filter cover is provided with an external air inlet with a metal filter screen inside, and the outer side surface of the detachable external filter cover is located at the periphery of the external air inlet and has an external threaded expansion frame protruding outward.

[0010] An internal push switch for controlling the electrically controlled boost fan is installed on the inner side of the external connection cover at one side of the lateral connecting port.

[0011] Both sides of the lateral linkage closing cover plate are provided with external closing protrusions for improving the sealing performance of the lateral closing.

[0012] An air flow sensor is fixedly mounted on the inner side surface of the inner communicating port.

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

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

[0015] The beneficial effects of the present 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, but also reduce the consumption of the oxygen tank by having an integral side booster cover on one side of the external connection cover;

[0017] (2) When worn alone, the electrically controlled booster fan inside the side booster hood can be used to pressurize and guide the outside air to the outside of the hood, greatly reducing the wearer's breathing difficulty and fatigue.

[0018] (3) By threading a detachable external filter cover at the opening position outside the lateral booster cover, the filtering effect can be increased by stacking, so that it can be adapted to various working environments;

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

[0020] (5) The entire device not only has electric air supply, but also has power supply for flip lighting, which greatly improves the functional integration. BRIEF DESCRIPTION OF THE DRAWINGS

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

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] Figure 1 , Figure 2 and Figure 3 A breathing mask with an electric air supply mechanism is shown, comprising 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 shell 3 for externally connecting an oxygen tank is clamped at the outer opening position of the external connecting cover 2, a side booster cover 4 with an integrated structure is located on the outside of the mask body 1 and is located on one side of the external connecting cover 2, an electrically controlled booster fan 5 is installed inside the side booster cover 4, a detachable external filter cover 41 is threadedly mounted at the outer opening position of the side booster cover 4, a side linkage closing cover plate 6 is elastically mounted at the inner connecting port position of the side booster cover 4 inside the external connecting cover 2, and an internal guide nozzle 7 for controlling the side linkage closing cover plate 6 is provided on the inner connecting surface of the external connecting cover shell 3.

[0028] Working principle: Mode 1: Use the air duct of the oxygen tank to connect the external connection cover 3, and then introduce the oxygen in the oxygen tank into the mask body 1 through the external connection cover 2; Mode 2: Use the air duct of the oxygen tank to connect the external connection cover 3, and then introduce the oxygen in the oxygen tank into the mask body 1 through the external connection cover 2, and at the same time, the electric-controlled booster fan 5 rotates at high speed to replenish the external air into the external connection cover 2, thereby reducing the consumption of the oxygen tank; Mode 3: Separate the external connection cover 3, and completely use the electric-controlled booster fan 5 to rotate at high speed to replenish the external air into the external connection cover 2.

[0029] In order to cooperate with external installation and separation, the outer opening position of the external connection cover 2 has an external assembly frame for fixing the external connection cover shell 3, and side snap-ins that cooperate with the external connection cover shell 3 are opened on both sides of the external assembly frame. The external connection cover shell 3 is inserted into the side snap-ins through the elastic buckles 8 on both sides of the connecting surface and fixed to the external assembly frame.

[0030] When disassembly is required, it is only necessary to press the elastic buckle 8 located in the lateral bayonet by hand, and then the external connection cover 3 will be separated from the external connection cover 2.

[0031] In order to cooperate with the lateral communication, a lateral communication opening that cooperates with the lateral linkage closing cover plate 6 and the internal guide nozzle 7 is opened on the outer wall of the external connection cover 2.

[0032] In order to cooperate with the external thread assembly, the outer periphery of the air inlet on the outside of the lateral boost cover 4 has an external thread assembly frame 9 of an integral structure protruding outward, and the detachable external filter cover 41 is sleeved on the outside of the external thread assembly frame 9 through the internal thread through hole on the assembly surface and is threadedly fixed to the lateral boost cover 4.

[0033] In order to cooperate with external expansion and freely increase or decrease the filtering mode and number of layers, an external air inlet with a metal filter 10 inside is opened on the outer side of the detachable external filter cover 41, and the outer side surface of the detachable external filter cover 41 is located outside the external air inlet and has an outwardly protruding external threaded expansion frame 11.

[0034] An air filter element is installed on the detachable external filter cover 41, and the filter element may be a PP cotton filter element or an activated carbon filter element.

[0035] In order to cooperate with the automatic control, an internal push switch 12 for controlling the electrically controlled boost fan 5 is installed on the inner side of the external connection cover 2 at one side of the lateral communication port.

[0036] When the boost mode is turned on, once the external connection cover 2 is separated from the external connection cover shell 3, the lateral linkage closing cover 6 will flip toward the inner opening of the lateral connecting port, and then squeeze the internal push switch 12 inside, and the internal push switch 12 will start the electrically controlled boost fan 5 to increase the pressure inside the mask.

[0037] In order to improve the closing effect, both sides of the lateral linkage closing cover plate 6 are provided with external closing protrusions 13 for improving the lateral closing sealing performance.

[0038] An electromagnetic valve is installed inside the external closed protrusion 13. In the boost mode, once the pressure inside the oxygen tank decreases, or people start the low-energy mode through an external switch, the external air will be drawn into the interior by starting the electromagnetic valve and the electrically controlled boost fan 5, and the oxygen tank will be used to supply air to the inside of the mask to reduce oxygen consumption.

[0039] In order to monitor the filtering effect, an air flow sensor 14 is fixedly installed on the inner side surface of the inner connecting port.

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

[0041] In order to cooperate with external assembly and adjustment, a flip-type external adjustment frame 15 is movably mounted on the outer side of the lateral boost cover 4 .

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

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

[0044] People manually control the flip-type external adjustment frame 15 to change the angle of the embedded LED lighting module 16 to control the lighting range.

[0045] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
