Description

Technical Field

[0001] This invention relates to the field of respiratory protection technology, specifically a plasma personal head-mounted multifunctional anti-smoke and anti-toxic dust mask. Background Technology

[0002] Currently, personal respiratory protective equipment mainly uses filter canister masks, with activated carbon adsorption or catalytic reaction technology as the core. These traditional masks have the following drawbacks: First, their protective principle relies on physical adsorption, which leads to adsorption saturation issues. The filter canisters are disposable, have a short lifespan, require frequent replacement, and are costly to use. Second, their protection range is limited; specific filter canisters can only target a limited number of toxic agents, failing to provide broad-spectrum protection against complex toxic gas environments. Third, they have high breathing resistance, which can cause discomfort with prolonged wear, affecting work efficiency and escape capabilities. Fourth, they lack effective inactivation methods against biological threats such as viruses and bacteria, making them unsuitable for protection during public health emergencies.

[0003] Therefore, there is an urgent need for a new type of personal respiratory protective equipment that provides an effective solution to the shortcomings of existing technologies. Summary of the Invention

[0004] The purpose of this invention is to provide a plasma personal head-mounted multifunctional anti-smoke and toxic micro-dust mask to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A plasma personal head-mounted multifunctional anti-smoke and toxic dust mask includes a mask body: the mask body has an exhalation port and an air inlet communicating with the external environment; The mask body is equipped with an air inlet valve, which is installed on the air inlet. The airflow guide pipe inside the air inlet valve is connected to the backpack-type low-temperature plasma generator through a pipe. The airflow guide pipe connects the inside and outside of the mask body. The low-temperature plasma generated by the low-temperature plasma generator comes into contact with the airflow about to enter the mask body and reacts, decomposing the toxic gases in the airflow into harmless substances.

[0006] Furthermore, the intake valve is detachably installed on the intake port, and the internal thread of the intake valve is threadedly connected to the intake port.

[0007] Furthermore, the outer end of the intake valve is provided with an external thread, and a dust cover is threaded onto the external thread.

[0008] Furthermore, the mask body also includes goggles, which are an integral part of the mask body; the edge contour of the goggles matches the skin around the eye socket, forming a ring seal when worn.

[0009] Furthermore, a mask strap is connected to the rear of the mask body, and a pair of support straps are provided at each end of the mask strap. The ends of the pair of support straps away from the mask strap are respectively connected to the edge of the goggles and the bottom of the mask body.

[0010] Furthermore, a helmet is also attached to the mask itself.

[0011] Furthermore, the helmet is equipped with ventilation holes.

[0012] Furthermore, an activated carbon filter element is also provided inside the dust cover.

[0013] Furthermore, the air inlet can be connected to an oxygen generator via a pipe. Compared with the prior art, the beneficial effects of the present invention are: 1. This invention generates low-temperature plasma using a backpack-type low-temperature plasma generator. Based on the principle of low-temperature plasma oxidation and decomposition, it achieves broad-spectrum and efficient purification of inhaled air, providing excellent protection against toxic, chemical, and smoke-borne micro-dust. Compared to traditional physical adsorption methods, it eliminates the problem of adsorption saturation and the need to replace consumables such as filter canisters, thus reducing long-term operating costs. The airflow guide tube ensures reaction efficiency, and the integrated goggles, along with the straps and support straps, provide excellent sealing and wearing stability.

[0014] 2. During operation, external air is first initially filtered by a dust cover to block large particles of impurities, and then enters the air intake valve for further purification, extending the service life of the core module. The dust cover and the air intake valve are connected by threads, making disassembly, cleaning, and replacement convenient and easy to maintain.

[0015] 3. This invention uses an activated carbon filter as a supplementary filtration layer to adsorb organic matter and odors, thereby improving the purity of the purification effect. Through a standard interface that can be connected to an oxygen generator, this invention can flexibly adapt to multiple gas supply modes: in a conventionally polluted environment, it uses a low-temperature plasma generator to achieve consumable-free, broad-spectrum purification; in extreme environments such as hypoxia or high-concentration pollution, it can switch to an external oxygen supply mode to provide the wearer with safe and reliable breathing protection.

[0018] 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.

[0019] Example 1: Please refer to Figures 1-4 A plasma personal head-mounted multifunctional anti-smoke and toxic dust mask includes a mask body 1: the mask body 1 has an exhalation port 2 and an air inlet 7 that communicates with the external environment. The mask body 1 is equipped with an air inlet valve 8, which is installed on the air inlet 7. The airflow guide pipe 803 inside the air inlet valve 8 is connected to the backpack-type low-temperature plasma generator through a pipe. The airflow guide pipe 803 connects the inside and outside of the mask body 1. The low-temperature plasma generated by the low-temperature plasma generator comes into contact with the airflow about to enter the mask body 1 and reacts, decomposing the toxic gases in the airflow into harmless substances.

[0020] The mask body 1 also includes goggles 6, which are an integral part of the mask body 1. The edge contour of the goggles 6 matches the skin around the eye socket and forms a ring seal when worn to prevent external smoke from entering the eyes.

[0021] The rear of the mask body 1 is connected to a mask strap 4, and each end of the mask strap 4 is provided with a pair of support straps 5. The ends of the pair of support straps 5 away from the mask strap 4 are respectively connected to the edge of the goggles 6 and the bottom of the mask body 1, for reliably fixing the mask body 1 to the wearer's head.

[0022] The working principle of this embodiment: The backpack-style low-temperature plasma generator is worn on both shoulders. High-concentration active particles, including high-energy electrons, ions, hydroxyl radicals (·OH), and oxygen radicals (·O), are generated inside the generator and enter the airflow guide tube 803 through a pipe. When the wearer inhales, external air enters the airflow guide tube 803 through the air inlet 7, making full contact with the aforementioned high-concentration active particles, achieving triple protection: the active particles break the molecular bonds of toxic gases (such as CO, HCN, SO, NH, VOCs, etc.), oxidizing and decomposing them into harmless substances such as CO, H2O, and N; high-energy electrons and hydroxyl radicals penetrate the cell walls of microorganisms and destroy their nucleic acid chains, achieving dual-pathway inactivation through physical penetration and chemical oxidation; particulate matter such as smoke and aerosols in the air are charged and deposited under the action of ions, achieving synergistic removal.

[0023] This embodiment utilizes a backpack-style low-temperature plasma generator to produce low-temperature plasma, achieving broad-spectrum and highly efficient purification of inhaled air based on the principle of low-temperature plasma oxidation decomposition. Compared to traditional physical adsorption methods, it avoids adsorption saturation issues and eliminates the need to replace consumables such as filter canisters, reducing long-term operating costs. Simultaneously, the airflow guide tube 803 ensures reaction efficiency, and the integrated goggles 6, along with the straps 4 and slings 5, provide excellent sealing and wearing stability.

[0024] Example 2: This embodiment is based on Embodiment 1. Please refer to... Figures 1-4 A plasma personal head-mounted multifunctional smoke and toxic dust mask has a structure that is basically the same as that of Example 1, except that: the outer end of the air inlet valve 8 is provided with an external threaded port 802, and a dust cover 9 is threadedly connected to the external threaded port 802.

[0025] Specifically, the intake valve 8 has an internal threaded port 801 and an external threaded port 802. The internal threaded port 801 is used for threaded connection with the air inlet 7 of the mask body 1, enabling detachable installation. The external threaded port 802 is used to connect to the dust cover 9, which can be made of metal or polymer material with a mesh or porous structure to prevent large particles, flying lint, and other impurities from directly entering the intake valve 8 without affecting gas flow.

[0026] The working principle of this embodiment is as follows: external air is first filtered by the dust cover 9 to block large particulate impurities, and then enters the air intake valve 8 for deep purification.

[0027] This embodiment effectively prevents large external particles from contaminating and impacting the internal discharge unit by installing a removable dust cover 9 at the outer end of the intake valve 8, thus extending the service life of the core module. The dust cover 9 is threadedly connected to the intake valve 8, facilitating disassembly, cleaning, and replacement, and providing high maintenance convenience.

[0028] Example 3: This example expands upon Example 1 or 2 by providing an implementation method that integrates the mask with a helmet. Please refer to... Figure 5 A plasma-based personal head-mounted multifunctional anti-smoke and anti-toxic micro-dust mask, whose core purification structure is the same as that of Embodiment 1 or 2, differs in that: a helmet 10 is also connected to the mask body 1. The helmet 10 is provided with ventilation holes 3.

[0029] Specifically, the helmet 10 is a protective helmet that meets safety standards, and the face mask body 1 is fixedly connected to the front of the helmet 10 by buckles, hinges, or threaded connectors. The ventilation holes 3 on the helmet 10 are used for heat dissipation and ventilation of the wearer's head to avoid stuffiness caused by wearing it for a long time.

[0030] The working principle of this embodiment is as follows: The wearer puts the helmet 10 on their head, and the mask body 1 is then fixed to the face. The inhalation purification process is the same as in embodiment 1, with external air purified by the intake valve 8 before being supplied for breathing. Exhalation is discharged through the exhalation port 2.

[0031] This embodiment integrates a protective mask with a helmet 10, suitable for scenarios requiring head protection such as fire rescue, military chemical defense, and engineering operations. The helmet 10 provides physical impact protection, while the mask provides respiratory protection. The ventilation holes 3 on the helmet 10 improve wearing comfort, making it suitable for extended work periods. Example 4: Based on Example 1, this example further includes an activated carbon filter element inside the dust cover 9, and the air inlet 7 can be connected to an oxygen generator via a pipe.

[0032] In this embodiment, the activated carbon filter is used to adsorb residual volatile organic gases, odors, and small amounts of byproducts that may be generated during the low-temperature plasma reaction in the air. As a supplementary treatment layer to the low-temperature plasma purification, it further improves the purity of the output gas. In addition, a standardized quick connector or threaded interface is provided at the air inlet (7), which can be connected to an external oxygen generator through a pressure-resistant hose. The oxygen generator can be a portable oxygen generator, oxygen cylinder, or centralized oxygen supply system to provide the wearer with high-concentration oxygen or pure air.

[0033] When the working environment presents an extreme risk of oxygen deficiency or the concentration of harmful gases exceeds the processing capacity of the low-temperature plasma generator, the air inlet 7 can be connected to an external oxygen generator via a pipe, allowing the oxygen generator to directly supply clean oxygen or compressed air into the mask. In a normally polluted environment, the external oxygen supply is shut off, and the low-temperature plasma generator is activated for active purification. With the dust cover 9 containing an activated carbon filter, external air sequentially passes through the dust cover 9 to block large particles, the activated carbon filter to adsorb some organic gases and odors, and the air inlet valve 8 to decompose toxic and harmful substances before entering the mask body 1 for the wearer to breathe.

[0034] This embodiment uses an activated carbon filter as a supplementary filtration layer, which can effectively adsorb organic matter and odors, improving the purity of the purification effect. By setting a standard interface that can be connected to an oxygen generator, this mask can flexibly adapt to multiple air supply modes: in a normal polluted environment, it can achieve consumable-free, broad-spectrum purification using a low-temperature plasma generator; in extreme environments such as hypoxia or high-concentration pollution, it can switch to an external oxygen supply mode, providing the wearer with safe and reliable breathing protection.
