[0048] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0049] As Figures 1-11 shown, a multifunctional personal protective equipment for coal mines in an embodiment of the present invention includes a helmet 10, a hood 20 and a backpack 70. The hood 20 is fixedly installed below the helmet 10. Through the hood 20, a sealed space can be formed for the human face to achieve full-face protection. The bottom of the hood 20 has an elastic tightening opening for the convenience of workers to wear. After wearing, the elastic tightening opening can automatically fit with the neck to achieve sealing. Through the physical protection of the helmet 10, combined with the respiratory protection and coal dust protection of the hood 20, comprehensive protection of the full face is achieved, preventing a coal-blackened face, which is beneficial to improving the working experience of workers and the industry image.

[0050] An eye window 40 and a breathing port 50 are fixedly installed on the hood 20. After the worker wears the equipment, a good field of vision can be obtained through the eye window 40. The breathing port 50 is located at the mouth and nose position. Through the breathing port 50, air can be injected into the interior of the hood 20 for the worker to breathe.

[0051] A sealing cover 60 is screwed onto the breathing port 50. A gas supply pipe 61 is fixedly installed on the sealing cover 60. The gas supply pipe 61 is used to introduce air into the interior of the hood 20.

[0052] Among them, the sealing cover 60 is assembled on the breathing port 50 by means of screw connection, so that it can be flexibly disassembled, so that the worker can open the breathing port 50 to complete actions such as drinking water.

[0053] As Figures 1-3 shown, a pair of straps 71 are fixedly installed on the backpack 70. Through the pair of straps 71, it is convenient for the worker to carry the backpack 70. A temperature adjustment mechanism and a battery 73 are fixedly installed inside the backpack 70. The battery 73 can supply power to the entire equipment.

[0054] The temperature adjustment mechanism includes a refrigeration box 74 and a blower 75. The output end of the blower 75 is communicated with the inside of the gas supply pipe 61, and the input end of the blower 75 is communicated with the inside of the refrigeration box 74. A semiconductor refrigeration chip is fixedly installed inside the refrigeration box 74. The semiconductor refrigeration chip can adjust the temperature of the air injected into the interior of the hood 20 to prevent a stuffy situation from occurring inside the hood 20.

[0055] Among them, inside the refrigeration box 74, it is not limited to a thermoelectric cooler, and other small air-conditioning systems can also be installed to adjust the air temperature.

[0056] A gas filter canister 72 is fixedly installed on the backpack 70. Inside the gas filter canister 72, a dust removal filter cotton and an activated carbon gas filter cartridge are installed in sequence, which can efficiently purify the toxic gases underground in the mine to obtain clean air for the workers to breathe, protecting the physical and mental health and life safety of the workers.

[0057] In addition, a porous end cap 721 is screwed onto the gas filter canister 72. The gas filter canister 72 is encapsulated through the porous end cap 721, and the internal components can be conveniently replaced by disassembling the porous end cap 721.

[0058] The gas filter canister 72 is connected and communicated with the inside of the refrigeration box 74. The clean air purified by the gas filter canister 72 can enter the inside of the refrigeration box 74. After the temperature is adjusted inside the refrigeration box 74, it is injected into the inside of the hood 20 through the air supply pipe 61 for the workers to breathe.

[0059] Specifically, after the worker wears this protective equipment, the fan 75 is started. The external air is purified by the gas filter canister 72 and then pumped into the inside of the refrigeration box 74. After the temperature is adjusted inside the refrigeration box 74, it is conducted through the air supply pipe 61 and finally injected into the inside of the hood 20 through the breathing port 50 for the workers to breathe. Ensure that the workers can breathe clean air, so that the workers can work safely, and can prevent the inside of the hood 20 from getting stuffy, greatly improving the comfort of wearing this equipment.

[0060] An oxygen tank 76 is also fixedly installed inside the backpack 70. Liquid oxygen is stored inside the oxygen tank 76. A bronchus 62 is fixedly connected in parallel to the air supply pipe 61. One end of the bronchus 62 far from the air supply pipe 61 is connected and communicated with the inside of the oxygen tank 76. That is, the oxygen inside the oxygen tank 76 can enter the inside of the air supply pipe 61 through the bronchus 62 to ensure that there is sufficient oxygen in the clean air.

[0061] Among them, a control valve 621 is fixedly installed on the bronchus 62. The on-off of the bronchus 62 can be controlled through the control valve 621 to flexibly control the oxygen supply.

[0062] Specifically, due to the poor air quality and low oxygen content underground in the mine, it is easy to cause brain hypoxia, thus triggering symptoms such as headache. Therefore, when the worker has symptoms such as shortness of breath or dizziness during the work underground in the mine, the control valve 621 can be opened, so that the oxygen stored inside the oxygen tank 76 can enter the inside of the air supply pipe 61 through the bronchus 62 and be mixed with the clean air inside the air supply pipe 61 to increase the oxygen content in the mixed air and prevent symptoms such as dizziness caused by hypoxia.

[0063] By matching with the backpack 70, some components of the equipment can be worn on the back, reducing its head volume and significantly reducing the load on the head when wearing the equipment, so as to improve the flexibility and comfort when working with the equipment.

[0064] As Figure 7 and Figure 8 shown, an exhaust structure is provided on the helmet 10. The exhaust structure includes a plurality of support blocks 15 provided on the inner wall of the helmet 10. After the worker wears the equipment, the plurality of support blocks 15 can support the head, so that the inside of the helmet 10 cannot fit closely with the scalp, thereby forming a slit between the inner wall of the helmet 10 and the worker's scalp for air flow.

[0065] Preferably, the plurality of support blocks 15 can be made of materials such as rubber or silica gel, with a soft texture to improve comfort.

[0066] As Figure 9 shown, an air collecting cavity 16 is provided between the inner and outer walls of the helmet 10. The inside of the plurality of support blocks 15 is a hollow structure, and the inside of the plurality of support blocks 15 is connected to the inside of the air collecting cavity 16. Among them, air outlet holes 151 are provided on the plurality of support blocks 15. After the air enters the slit between the inner wall of the helmet 10 and the worker's scalp, it can enter the inside of the air collecting cavity 16 through the air outlet holes 151 on the support blocks 15, realizing the discharge of air, so that while the air in the helmet 10 and the hood 20 is continuously supplied, it is discharged in time to form an air flow effect, ensuring the air quality inside the helmet 10 and the hood 20 and improving the user experience.

[0067] It should be noted that heat can be quickly carried away through air flow, avoiding the situation of fog on the inner wall of the eye window 40, ensuring clear vision and facilitating the worker's work.

[0068] In addition, during the process of air passing through the slit between the inner wall of the helmet 10 and the worker's scalp, it can also realize the timely heat dissipation of the worker's head, preventing the situation of sweating due to the inability to dissipate heat caused by the close contact between the scalp and the inner wall of the helmet 10, and further improving the comfort when working with the equipment.

[0069] As Figure 10 shown, two groups of exhaust pipes 14 are fixedly installed on the helmet 10, and both groups of exhaust pipes 14 are connected to the inside of the air collecting cavity 16. The air entering the inside of the air collecting cavity 16 can be discharged through the two groups of exhaust pipes 14.

[0070] As Figure 5 and Figure 10 shown, a transparent lens 41 and a groove 42 are provided on the eye window 40. The staff can view the external environment through the transparent lens 41. A transfer cavity 43 is provided inside above the groove 42, and one end of the exhaust pipe 14 is connected to the inside of the transfer cavity 43. The air entering the inside of the exhaust pipe 14 can enter the inside of the transfer cavity 43.

[0071] As Figure 6 and Figure 11 shown, a blowing component is provided on the upper end surface inside the groove 42. The blowing component includes a first blowing port 421 and a second blowing port 422, and both the first blowing port 421 and the second blowing port 422 are communicated with the inside of the transfer cavity 43. That is, the air entering the inside of the transfer cavity 43 can be blown out through the first blowing port 421 and the second blowing port 422.

[0072] Among them, the first blowing port 421 is vertically downward, and the gas blown out through the first blowing port 421 can form a vertical air curtain at the front end of the transparent lens 41. Through this air curtain, the inside of the groove 42 can be sealed, so that dirt such as dust cannot enter the inside of the groove 42, so as to isolate and protect the transparent lens 41. The second blowing port 422 is inclined toward the transparent lens 41, and the gas blown out through the second blowing port 422 can blow and clean the surface of the transparent lens 41 to remove the dirt attached to the surface of the transparent lens 41.

[0073] Specifically, after the clean air enters the inside of the hood 20 through the breathing port 50, it will flow upward and evenly enter the inside of the air collecting cavity 16 through the air outlet holes 151 on several support blocks 15, and then be introduced into the inside of the transfer cavity 43 through the exhaust pipe 14, and finally be blown out through the first blowing port 421 and the second blowing port 422, realizing the isolation protection and blowing cleaning of the transparent lens 41, preventing the surface of the transparent lens 41 from being polluted, ensuring that the workers can work with a clear vision when wearing, so as to adapt to the special environment of the coal mine.

[0074] As Figure 1 and Figure 4 shown, a communication base 30 is fixedly installed on the top of the helmet 10, and a sensor group 34 and a lighting component are installed on the communication base 30. Among them, the lighting component includes a main lamp 32 and a secondary lamp 33, and both the main lamp 32 and the secondary lamp 33 are rotatably connected to the communication base 30 and can freely adjust the angle. By using the main lamp 32 and the secondary lamp 33 in cooperation, the lighting range can be effectively increased, so that the workers do not have to deliberately lower their heads to illuminate the road. At the same time, both the main lamp 32 and the secondary lamp 33 are powered by the battery 73 and do not require an independent battery, and can be used for a long time.

[0075] The sensor group 34 includes but is not limited to an air monitoring sensor and a position sensor. Through the air monitoring sensor, the air environment in the mine can be monitored in real time, and through the position sensor, the position of the worker can be located in real time, realizing the real-time monitoring of the worker's working environment and location.

[0076] An antenna 35 and an alarm light 36 are also fixedly installed on the communication base 30. Through the antenna 35, the equipment can establish wireless communication with the outside world, thus realizing the remote monitoring of the equipment. The alarm light 36 is matched with the sensor group 34. When abnormal situations are detected, such as abnormal environment, abnormal position of the worker, etc., it will automatically turn on and emit a warning signal to enhance the functionality of the equipment.

[0077] A power cord 31 is connected between the communication base 30 and the battery 73. Through the power cord 31, the communication base 30 can be powered. Among them, the power cord 31 passes through the inside of the air supply pipe 61, making the power cord 31 and the air supply pipe 61 an integrated whole, improving the cleanliness of the device, facilitating wearing and not causing trouble to the worker during work.

[0078] As Figure 5 shown, a headset 11 is fixedly installed on the helmet 10. After the worker wears this equipment, it means that the headset 11 is automatically worn. Through the headset 11, the noise can be effectively reduced.

[0079] A microphone 13 is fixedly installed on the breathing port 50. A connecting wire 12 is arranged between the headset 11 and the microphone 13. The worker can communicate through the microphone 13 for work communication in a noisy environment.

[0080] Specifically, due to the high noise and inconvenient communication in the coal mine underground, it affects the work communication of the workers and reduces the work efficiency. By wearing this protective equipment, the function of noise prevention can be realized through the headset 11, avoiding the harm of noise to the health of the workers. At the same time, the worker can use the microphone 13 in combination with the headset 11 to conduct work communication in the noisy mine, which is beneficial to improving the work efficiency.

[0081] During use, the worker wears this equipment to work underground. Their head and face can be fully protected, breathe clean air, and the air temperature can be adjusted. Without generating a stuffy feeling on the premise of ensuring full protection, it guarantees the comfort of wearing this equipment during work. At the same time, the vision of this equipment is not easily affected, and it has functions such as noise reduction, intelligent monitoring, danger warning, and dialogue communication, enabling the worker to work underground safely, conveniently, and efficiently while wearing this equipment.

[0082] Compared with the prior art, the present invention can achieve comprehensive facial protection through the helmet 10 and the headgear 20, ensuring that the user can be fully protected in various environments, and also guaranteeing the cleanliness of the worker's face and improving the work comfort of the worker;

[0083] Through the temperature control mechanism and the gas filter canister 72, clean air at a suitable temperature can be continuously provided inside the helmet 10 and the hood 20, and the air inside the helmet 10 and the hood 20 can be kept flowing continuously, ensuring the purity of the air that the worker breathes, making the worker feel more comfortable and natural when breathing during work, and greatly reducing the stuffy feeling of the worker during work, thus enhancing the wearing comfort;

[0084] By designing the exhaust structure and the blowing assembly, the gas discharged from inside the helmet 10 and the hood 20 can be used to isolate and protect the transparent lens 41, preventing the transparent lens 41 from being contaminated, ensuring that the user has a clear field of vision when wearing, so as to adapt to the special environment of the coal mine;

[0085] Intelligent communication can be achieved through the communication base 30, which is convenient for remote monitoring of the equipment. A sensor group 34 and a lighting assembly are mounted on the communication base 30, improving the reliability, safety and convenience of the equipment.

[0086] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
