Detailed Implementation

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] like Figures 1 to 7 As shown, a portable active air-supplying multi-stage purification respirator includes a mounting shell 10. The mounting shell 10 contains a battery chamber 101, an air supply chamber 102, and a receiving chamber 103 arranged in a row. This integrated layout is compact and modular, facilitating assembly and maintenance, while effectively shortening the airflow path, reducing wind resistance, and improving air supply efficiency. The battery cavity 101 has a top opening and a bottom seal, and a battery block 13 is detachably installed inside it. The top opening design facilitates quick battery replacement, while the bottom seal prevents dust or liquid from seeping in from the bottom, ensuring electrical safety.

[0029] The top and bottom of the air supply chamber 102 are sealed, and a brushless motor 14 is fixedly connected inside. A turbine fan blade 141 is installed at the output end of the brushless motor 14. The front side of the air supply chamber 102 has a pair of vertically distributed air inlets 102a. An activated carbon filter box 16 is detachably connected to the outside of each air inlet 102a. The outer end face of the activated carbon filter box 16 is connected to a multi-layer filter cotton 18 by a clamp 17. An air outlet 102b is provided between the air supply chamber 102 and the receiving chamber 103. The vertically arranged double air inlets 102a, together with the two sets of activated carbon filter boxes 16 and the multi-layer filter cotton 18, form a double pre-filtration, effectively intercepting large particles and harmful gases in highly polluted environments such as welding. The brushless motor 14 operates smoothly, has a long lifespan, and low noise, making it suitable for long-term operation. The fully enclosed structure of the air supply chamber 102 prevents unfiltered air from mixing in, ensuring the purity of the purified airflow.

[0030] The receiving cavity 103 has openings at both the top and bottom. A transparent filter bottle 20 is housed within the cavity 103. A sealing cap 21 is threaded onto the top of the filter bottle 20. The sealing cap 21 has an air inlet 21a and an air outlet 21b. The air inlet 21a is connected to the air outlet 102b via an angle valve 19. An air guide tube 22 is sealed to the inner end of the air inlet 21a. Air guide holes 22a are evenly distributed at the bottom of the air guide tube 22, and these holes are submerged in the mineral water or purified water within the filter bottle 20. This water washing method deeply purifies the pre-filtered airflow, efficiently dissolving residual acidic gases (such as HF and HCl) and fine particulate matter. The transparent filter bottle 20 facilitates observation of water level and quality. The angle valve 19 allows for easy adjustment of airflow or emergency shut-off. The submerged design of the air guide holes 22a ensures sufficient dispersion of air bubbles, improving gas-liquid contact efficiency and enhancing the purification effect.

[0031] In this embodiment, the bottom of the battery block 13 is provided with a conductive post 131, and the bottom of the battery cavity 101 is provided with a conductive seat 132 that mates with the conductive post 131. The bottom-plug-in electrical connection structure ensures stable installation and reliable contact, preventing power outages due to shaking and simplifying battery replacement operations.

[0032] In this embodiment, a toggle switch 15 is installed on the top of the air supply chamber 102, and the toggle switch 15 is electrically connected between the battery block 13 and the brushless motor 14. The switch is located on the top for easy one-handed operation by the user, allowing the air supply to be started and stopped without removing the device, thus improving ease of use and operational safety.

[0033] In this embodiment, a pair of symmetrical access ports 101a are provided on the upper part of the battery cavity 101. The access ports 101a provide space for fingers to exert force, making it easier to remove the battery block 13 and solving the problem of traditional closed-cavity batteries being difficult to pull out.

[0034] In this embodiment, an observation port 103a is centrally located on the front side of the receiving cavity 103. The observation port 103a allows for real-time monitoring of the water level and turbidity within the filter bottle 20, providing timely reminders to the user to replace the purified water and prevent purification failure.

[0035] In this embodiment, an upper sealing plate 104 and a lower sealing plate 105 are detachably connected to the upper and lower ends of the receiving cavity 103. The upper sealing plate 104 is provided with a through groove 104a and a through hole 104b. The upper sealing plate 104 and the lower sealing plate 105 can protect the filter bottle 20 inside the receiving cavity 103. The detachable sealing plate structure facilitates the removal of the filter bottle as a whole for cleaning or replacement. The through groove 104a on the upper sealing plate 104 allows the hand-tightening structure of the angle valve 19 to pass smoothly, and the through hole 104b allows the air supply pipe connected to the air outlet 21b to pass smoothly.

[0036] In this embodiment, a belt clip 12 is fixedly connected to the rear side of the mounting shell 10. The belt clip 12 is used to firmly clamp the respirator main unit onto the work pants belt, freeing up the hands, facilitating the movement of the operator, and improving portability and comfort.

[0037] In this embodiment, a battery power indicator module 133 is centrally located on the top surface of the battery block 13. The power indicator module 133 (such as an LED light or a digital screen) can intuitively display the remaining power, avoiding power outages during operation and ensuring continuous protection safety.

[0038] In this embodiment, a water baffle 23 is fixedly connected to the upper part of the air duct 22, and air vents 23a are evenly distributed on the water baffle 23. The water baffle 23 effectively blocks water droplets carried by the airflow from splashing upwards, preventing water from entering the subsequent air path or mask, while the air vents 23a ensure smooth airflow, achieving "airflow with water resistance", thus improving wearing comfort and system reliability.

[0039] In this embodiment, the overall dimensions of the respirator are: length 160mm, width (thickness) 10cm, and height 16mm.

[0040] In this embodiment, the mounting shell 10, the upper sealing plate 105, and the lower sealing plate 105 are all made of fire-retardant materials.

[0041] In this embodiment, the filter bottle 20, sealing cap 21, air duct 22, water baffle 23, air delivery tube, and the breathing mask worn are all made of food-grade materials.

[0042] In this embodiment, the specific value of the triple filtration structure for different job types is shown in the table below:

[0043] This respirator employs a triple purification mechanism of "physical interception (filter cotton) + chemical adsorption (activated carbon) + dissolution and washing (water washing)" to simultaneously protect against particulate matter, toxic organic vapors, and irritating gases. It significantly improves breathing safety and wearing comfort in high-risk work environments such as welding, grinding, sandblasting, and painting, and effectively prevents occupational respiratory diseases.

[0044] The working process of a portable active air supply multi-stage purification respirator is as follows: In use, the respirator main unit is secured to the waistband using the belt clip 12. Turning on the top toggle switch 15 powers the brushless motor 14 via the battery pack 13, driving the turbine fan 141 to rotate and creating negative pressure within the air delivery chamber 102. External air passes through the upper and lower air inlets 102a sequentially through multi-layered filter cotton 18 and activated carbon filter cartridge 16, completing the initial filtration of large particles and organic vapors. The purified airflow enters the air duct 22 through the air outlet 102b and angle valve 19, and is then introduced into the water in the filter bottle 20 in the form of bubbles through the air vent 22a, achieving deep water washing purification of acidic gases and residual particles. Clean, humidified air is discharged from the air outlet 21b and delivered to the mask for the user to breathe through the trachea. The entire process achieves a three-stage synergy of "primary filtration—chemical adsorption—water washing purification," ensuring respiratory safety.

[0045] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
