Description

Technical Field

[0001] This utility model relates to the field of air respirator technology, and in particular to an air respirator with a water replenishment function. Background Technology

[0002] As a core protective equipment in high-risk scenarios such as chemical toxic gas leaks and underground mining operations, air respirators are often worn continuously for several hours to isolate users from harmful environments. However, existing equipment generally lacks a suitable water replenishment design: prolonged enclosed wear leads to poor air circulation inside the mask, which can easily cause dry and cracked facial skin and dry and uncomfortable respiratory mucosa. This not only reduces concentration but also increases the burden on the user's body. Removing the mask to replenish water exposes the user to toxic and harmful environments, greatly increasing the risk of poisoning and burns. Even if a few devices have a water replenishment function, there are problems such as uneven water mist dispersion, interference with breathing airflow, or the inability to recycle water resources, requiring frequent refills that affect the continuity of work. These issues make it difficult to meet the safe and continuous use requirements in high-risk scenarios and bring certain adverse effects to users. To address the shortcomings of existing technologies, we propose an air respirator with a water replenishment function. Utility Model Content

[0003] The main objective of this invention is to provide an air respirator with a water replenishment function, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An air respirator with a hydration function includes an air respirator mask. A transparent face mask is sealed to the surface of the air respirator mask, and an air inlet connector is sealed to the lower part of the transparent face mask. One end of the air inlet connector is detachably connected to a connecting pipe, and the other end of the connecting pipe is detachably connected to an air collection pipe. Air delivery pipes are detachably connected to both sides of the air collection pipe. A silicone sealing gasket is sealed to one edge of the air respirator mask, and multiple elastic bands are fixedly installed on one side of the silicone sealing gasket. Circular pads are fixedly installed at the rear of the multiple elastic bands. A connecting pipe is fixedly connected to the lower end of the air respirator mask. A water storage box is fixedly connected to the lower end of the connecting pipe, and a miniature water pump is installed at the bottom of the water storage box. The miniature water pump is detachably connected to a first water supply pipe on both sides. The surface of the air breathing mask is sealed with two first diversion boxes and a second diversion box, and both first diversion boxes are connected to the second diversion box through a second water supply pipe. Multiple atomizing nozzles are detachably installed inside the two first diversion boxes and the second diversion box. A filter screen and an activated carbon layer are detachably connected inside the water storage box. A water injection pipe is fixedly connected to one side of the water storage box, and a one-way valve is detachably connected to the middle of the water injection pipe.

[0005] Preferably, the miniature water pump is detachably connected to the bottom of the water storage box via countersunk bolts. The control terminal of the miniature water pump is electrically connected to an external push switch. The external push switch is fixed to the outer surface of the transparent mask with waterproof adhesive, and the external push switch and the miniature water pump are electrically connected to form a control circuit.

[0006] Preferably, two first diversion boxes are symmetrically embedded on the surface of the air respirator near the two sides of the transparent face mask, and a second diversion box is embedded on the surface of the air respirator near the top. Multiple atomizing nozzles are installed inside the first and second diversion boxes. The spray direction of the atomizing nozzles forms an acute angle with the inner wall of the air respirator, and the atomized particles of the atomizing nozzles are in the micron range. The connection between the atomizing nozzles and the first and second diversion boxes is fitted with nitrile rubber sealing rings.

[0007] Preferably, the inner wall of the water storage box has two sets of slots symmetrically arranged along the height direction. The two sets of slots correspond to the installation height of the filter screen and the activated carbon layer, respectively. The filter screen is a double-layer stainless steel filter screen with a fine pore size and the edge of the filter screen is wrapped with silicone. The activated carbon layer is a granular coconut shell activated carbon layer with an appropriate particle size. The activated carbon layer is wrapped with a breathable non-woven bag on the outside, and the edge of the breathable non-woven bag is fixed to the inner wall of the water storage box by Velcro.

[0008] Preferably, there are multiple elastic bands symmetrically distributed on the upper and lower sides of the silicone sealing gasket. The elastic bands are made of a high-elasticity spandex and nylon blend material with high elongation at break. The circular pad is made of memory foam material.

[0009] Preferably, the inner side of the connection end between the air inlet connector and the connecting pipe is machined with an internal thread, and the outer side of the corresponding end of the connecting pipe is machined with a matching external thread. The air inlet connector and the connecting pipe have sufficient thread connection length. The connection method between the connecting pipe and the air collecting pipe is a quick-connect connection. The corresponding connection end of the air collecting pipe is provided with an elastic buckle. The outer wall of the connecting pipe is provided with an annular groove that matches the elastic buckle. The air supply pipe is a high-pressure hose made of PU material. The air supply pipe has an appropriate inner diameter and wall thickness, and the outer side of the air supply pipe is fitted with a spiral steel wire reinforcement layer.

[0010] Compared with the prior art, the present invention has the following beneficial effects: This air respirator with a hydration function utilizes a double-layer stainless steel filter and a granular coconut shell activated carbon layer in its water tank to filter impurities and absorb odors from the spray water flowing back through the connecting pipe. This allows for the recycling of hydration water resources, eliminating the need for frequent refilling and significantly improving ease of use while reducing consumable costs. Simultaneously, the atomizing nozzle employs a micron-level atomizing particle structure with an acute angle between the spray direction and the inner wall of the air respirator. This ensures that the hydration mist is evenly dispersed within the respirator, effectively alleviating dryness and discomfort on the face and respiratory tract during prolonged wear, while also preventing the mist from directly interfering with airflow and ensuring smooth breathing. This makes it suitable for extended use in high-risk work environments such as firefighting and chemical plants.

[0011] This air respirator with hydration function combines a silicone sealing gasket with a high-elasticity spandex and nylon blend elastic band. The silicone sealing gasket can closely conform to the facial contours, effectively blocking harmful external gases from seeping into the mask and improving breathing safety. The high elongation at break of the elastic band can adapt to different head sizes, and the memory foam round pad supports the back of the head, distributing wearing pressure and avoiding local pressure pain caused by prolonged use, greatly improving wearing comfort. In addition, the threaded sealing connection between the air inlet connector and the connecting pipe, the quick-connect buckle connection between the connecting pipe and the air collection pipe, and the PU material with spiral steel wire reinforcement layer design of the air delivery pipe ensure that all connection parts are stable and damage-resistant. The air delivery pipe has strong pressure resistance, reducing the risk of air leakage and detachment during use and extending the overall service life of the device. Attached Figure Description

[0014] 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.

[0015] Example 1, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an air respirator with a hydration function includes an air respirator 1, a transparent face mask 2 sealed and installed on the surface of the air respirator 1, an air inlet connector 3 sealed and installed at the lower part of the transparent face mask 2, and a connecting pipe 4. One end of the connecting pipe 4 is detachably connected to the inner thread of the air inlet connector 3 via an external thread, and the thread length meets the sealing requirements. The other end of the connecting pipe 4 is connected to the air collection pipe 5 via a quick-connect connection. Specifically, the elastic buckle at the corresponding connection end of the air collection pipe 5 is inserted into the annular groove on the outer wall of the connecting pipe 4 for fixation. Both sides of the air collection pipe 5 are detachably connected to the air delivery pipe 6, which is made of PU high-pressure flexible material. The air respirator 1 is reinforced with a spiral steel wire sleeve on its outer side. A silicone sealing gasket 7 is installed on one edge of the air respirator 1. Multiple elastic bands 8 made of high-elasticity spandex and nylon blend are fixedly installed symmetrically along the upper and lower edges of the silicone sealing gasket 7. A circular pad 9 made of memory foam is fixedly installed at the rear of the elastic bands 8. The lower end of the air respirator 1 is fixedly connected to a connecting pipe 10. The lower end of the connecting pipe 10 is fixedly connected to a water storage box 11. The bottom of the water storage box 11 is detachably connected to a miniature water pump 12 via countersunk bolts. The two sides of the miniature water pump 12 are detachably connected to the first water supply pipe 13, and the other end of the first water supply pipe 13 is connected to the air respirator 1. The first diversion box 14 is connected to the surface of the suction mask 1 and sealed. Two first diversion boxes 14 are symmetrically embedded near the two sides of the transparent mask 2. The second diversion box 15 is embedded near the top of the air breathing mask 1. Both first diversion boxes 14 are connected to the second diversion box 15 through the second water supply pipe 16. Multiple atomizing nozzles 17 can be detachably installed on the inner side of both the first diversion box 14 and the second diversion box 15. The connection between the atomizing nozzle 17 and the diversion box is fitted with a nitrile rubber sealing ring. The spray direction of the atomizing nozzle 17 forms an acute angle with the inner wall of the air breathing mask 1, and the atomized particles are in the micron range. Two sets of slots are symmetrically provided on the inner side wall of the water storage box 11 along the height direction. They are respectively installed with a filter screen 18 with a double-layer stainless steel fine filter screen wrapped with silicone edge and an activated carbon layer 19 with granular coconut shell activated carbon wrapped with a breathable non-woven bag on the outside and fixed to the inner side wall of the water storage box 11 by Velcro. A water injection pipe 20 is fixedly connected to one side of the water storage box 11. A one-way valve 21 is detachably connected to the middle of the water injection pipe 20. The control end of the micro water pump 12 is electrically connected to an external push switch. The external push switch is fixed to the outer surface of the transparent mask 2 with waterproof adhesive and forms a control circuit with the micro water pump 12.

[0016] It should be noted that this utility model is an air respirator with a water replenishment function. In use, first, purified water is injected into the water storage box 11 through the water injection pipe 20. The one-way valve 21 effectively prevents water backflow. Then, the user wears the air respirator 1 on their face. The silicone sealing pad 7 fits tightly to the face to ensure a tight seal. The symmetrically distributed elastic bands 8 are adjusted to securely hold the air respirator 1 in place. The memory foam circular pad 9 fits against the back of the head to improve comfort during extended wear. Next, the air supply pipe 6 is connected to an external air source. Clean external air enters the air collection pipe 5 through the air supply pipe 6 and then flows through the connecting pipe 4 and the air inlet connector 3 into the air respirator 1, providing the user with the necessary breathing air. When the user feels dryness in their facial skin or respiratory tract during wear and needs hydration, they simply press the outer surface of the transparent mask 2. An external push-button switch controls the start of the micro water pump 12. Under the power of the micro water pump 12, the purified water in the water storage box 11 is delivered to the first distribution box 14 and the second distribution box 15 through the first water supply pipe 13. The water flow between the distribution boxes is evenly distributed through the second water supply pipe 16. Finally, multiple atomizing nozzles 17 spray micron-sized fine atomized particles at an acute angle to the inner wall of the air breathing mask 1 into the space inside the mask. Without interfering with the user's normal breathing airflow, it provides a gentle and even hydration effect to the user's face and respiratory tract, effectively relieving dryness and discomfort. At the same time, the purified water that falls to the bottom of the air breathing mask 1 after spraying will flow into the water storage box 11 through the connecting pipe 10. After being filtered and purified by the filter screen 18 and the activated carbon layer 19, it falls to the bottom of the water storage box 11 for the user to use repeatedly.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
