Abstract
Description
Technical Field
[0001] This utility model relates to the field of protective mask technology, specifically to a protective mask for extracting silymarin. Background Technology
[0002] The extraction of silymarin requires the use of organic solvents such as methanol, ethanol, acetone, and ethyl acetate. During the extraction process, organic solvents will evaporate and produce irritating odors or harmful gases. Long-term inhalation can damage the respiratory system and other organs of workers. It may also produce liquid splashes or particulate suspensions, which can cause skin damage upon contact with the skin. Therefore, protective masks are required during the production and extraction of silymarin to protect the respiratory system and facial skin of workers.
[0003] Currently, the protective masks used in the production and processing of silymarin are designed as an integral part of the protective suit. The purpose is to ensure the cleanliness of the processing environment and provide all-round protection for the workers. The edges of the protective mask and the edges of the face opening of the protective suit are reliably fixed and sealed by adhesive. The protective effect of the protective mask will gradually deteriorate with the increase of use time. In order to protect the health of the workers, the protective mask needs to be replaced. When replacing it, the protective suit must be replaced at the same time. In workshops with high concentrations of irritant gases, workers need to change their protective masks multiple times a day. On the one hand, the process of changing the protective suit is cumbersome and time-consuming, reducing labor efficiency. On the other hand, the fact that the protective suit must be changed at the same time also leads to high production costs.
[0004] Therefore, a protective mask for extracting silymarin is proposed. Utility Model Content
[0005] The purpose of this invention is to provide a protective mask for extracting silymarin, in order to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0007] A protective mask for extracting silymarin includes a shell, ear brackets fixedly installed on both the left and right sides of the back of the shell, an eyepiece and a detachable filter mechanism fixedly installed on the front of the shell, a protruding ring and a fixing frame fixedly installed on the front of the shell, the protruding ring and the fixing frame being arranged in a ring shape along the edge of the shell, the fixing frame being located inside the protruding ring, and a pressure ring being sleeved on the surface of the protruding ring, the protruding ring and the pressure ring being used to compress and fix the protective clothing fabric, and fixing components for fixing the pressure ring being provided on the surfaces of the protruding ring, the fixing frame and the pressure ring.
[0008] Furthermore, a moisture-absorbing frame is fixedly installed on the back of the cover, the moisture-absorbing frame is arranged around the periphery of the eyepiece, and the moisture-absorbing frame is made of dry wood pulp sponge material.
[0009] Furthermore, the detachable filter mechanism includes an inner vent plate, which is fixedly installed on the surface of the cover.

[0024] like Figures 1 to 3As shown, a protective mask for extracting silymarin includes a cover 1. Ear brackets 2 are fixedly installed on both the left and right sides of the back of the cover 1. An eyepiece 3 and a detachable filter mechanism 5 are fixedly installed on the front of the cover 1. A protruding ring 6 and a fixing frame 7 are fixedly installed on the front of the cover 1. The protruding ring 6 and the fixing frame 7 are both arranged in a ring shape along the edge of the cover 1. The fixing frame 7 is located inside the protruding ring 6. A pressure ring 8 is sleeved on the surface of the protruding ring 6. The protruding ring 6 and the pressure ring 8 are used to squeeze and fix the protective clothing fabric. Fixing components 9 for fixing the pressure ring 8 are provided on the surface of the protruding ring 6, the fixing frame 7 and the pressure ring 8.
[0025] More specifically, by placing the edge fabric of the face opening of the protective suit on the front of the convex ring 6, and then fitting the pressure ring 8 onto the outside of the convex ring 6, while using the fixing component 9 to reliably fix the pressure ring 8 between the convex ring 6 and the fixing frame 7, the convex ring 6 and the pressure ring 8 cooperate to squeeze and fix the fabric, achieving rapid installation of the entire protective mask. Furthermore, the cooperation of the convex ring 6, the pressure ring 8, and the fixing component 9 ensures a tight and seamless connection between the protective mask and the fabric, providing a good sealing effect and facilitating disassembly and assembly. When replacing the protective mask, there is no need to replace the protective suit as well, effectively saving costs and eliminating the time spent on changing protective clothing, thus effectively improving production efficiency. By placing the ear bracket 2 on the ears, the protective mask is supported and positioned, preventing the protective mask from moving downwards under gravity and causing deformation of the protective suit, ensuring that workers can observe the external situation through the eyepiece 3.
[0026] A moisture-absorbing frame 4 is fixedly installed on the back of the cover 1. The moisture-absorbing frame 4 surrounds the eyepiece 3 and is made of dry wood pulp sponge material.
[0027] Specifically, the wood pulp sponge material has good water absorption. By setting a moisture-absorbing frame 4 around the eyepiece 3, the moisture generated by breathing can be effectively absorbed, preventing moisture from condensing on the inside of the eyepiece 3 and affecting vision.
[0028] The detachable filter mechanism 5 includes an inner vent plate 501, which is fixedly installed on the surface of the cover 1. An installation cylinder 502 is fixedly installed on the front of the inner vent plate 501. An installation cover 503 is threadedly installed on the outer surface of the installation cylinder 502. A filter bag 504 is placed inside the installation cylinder 502.
[0029] Specifically, the mounting cover 503 can be quickly disassembled and assembled by rotating the mounting cover 503, and the filter bag 504 placed inside the mounting cylinder 502 can be replaced. After the protective mask is fully disinfected and purified, the filter bag 504 can be replaced and the mask can be put into use again, so that the protective mask can be reused multiple times, further saving production costs.
[0030] The mounting cover 503 includes a vent 5031, which is threaded onto the outer surface of the mounting cylinder 502. A sealing ring 5032 is fixedly installed on the back of the front side wall of the vent 5031. The sealing ring 5032 is fitted against the front of the mounting cylinder 502. A filter sheet 5033 is fixedly installed on the inner surface of the sealing ring 5032. Ventilation holes 505 are provided on the front of both the inner vent plate 501 and the vent 5031.
[0031] Specifically, the vent 5031 can be quickly disassembled and assembled by rotating the vent 5031. The sealing ring 5032 is used to improve the sealing between the vent 5031 and the mounting cylinder 502. The filter sheet 5033 is used to perform preliminary filtration of the inhaled gas, filtering out dust and splashed liquid. Then, the gas is further filtered through the filter bag 504.
[0032] The fixing component 9 includes a threaded through hole 901, an insertion hole 902, a positioning hole 903, and a threaded post 904. The threaded through hole 901 is opened on the inner surface of the fixing frame 7, the insertion hole 902 is opened on the inner wall surface of the pressure ring 8, and the positioning hole 903 is opened on the inner surface of the convex ring 6. The threaded through hole 901, the insertion hole 902, and the positioning hole 903 are coaxially arranged. The threaded post 904 is threadedly installed on the inner wall surface of the threaded through hole 901 and passes through the insertion hole 902 and is inserted into the positioning hole 903. There are several fixing components 9.
[0033] Specifically, by rotating the threaded post 904, the threaded post 904 can be fixedly installed in the threaded through hole 901 and pass through the insertion hole 902 into the positioning hole 903. When the threaded post 904 enters the positioning hole 903, it will squeeze some of the fabric into the positioning hole 903, thereby further reinforcing the fabric and making the fabric more firmly and reliably fixed. It also completes the fixation of the pressure ring 8. By rotating the threaded post 904 in the opposite direction, the threaded post 904 can be removed from the threaded through hole 901. At this time, the pressure ring 8 can be removed, and then the entire protective mask can be removed.
[0034] The first rubber ring 10 is fixedly installed on the front of the convex ring 6, and the second rubber ring 11 is fixedly installed on the front of the inner side wall of the pressure ring 8.
[0035] Specifically, when the convex ring 6 and the pressure ring 8 work together to compress and fix the fabric, the elastic cooperation of the first rubber ring 10 and the second rubber ring 11 improves the sealing performance when compressing and fixing the fabric, and provides elastic space for the pressure ring 8, ensuring that the threaded post 904 can still be smoothly inserted into the positioning hole 903 after the fabric is clamped, so as to fix the pressure ring 8. In addition, the first rubber ring 10 and the second rubber ring 11 can increase the friction on the surface of the fabric, thereby further increasing the reliability of compressing and fixing the fabric.
[0036] In summary: By placing the edge fabric of the face opening of the protective suit on the front of the convex ring 6, and then fitting the pressure ring 8 onto the outside of the convex ring 6, while using the fixing component 9 to reliably fix the pressure ring 8 between the convex ring 6 and the fixing frame 7, the convex ring 6 and the pressure ring 8 cooperate to compress and fix the fabric, achieving rapid installation of the entire protective mask. Furthermore, the cooperation of the convex ring 6, the pressure ring 8, and the fixing component 9 ensures a tight and seamless connection between the protective mask and the fabric, providing excellent sealing and facilitating easy assembly and disassembly. When replacing the protective mask, there is no need to replace the protective suit, effectively saving costs and eliminating the time-consuming process of changing protective clothing, thus significantly improving production efficiency. By placing the ear bracket 2 on the ears, the protective mask is supported and positioned, preventing it from shifting downwards under gravity and causing deformation of the protective suit, ensuring that workers can observe the external situation through the eyepiece 3.
