Description

Technical Field

[0001] This invention belongs to the field of medical protective equipment technology, and specifically relates to a drawer-type movable dust mask with a replaceable core. Background Technology

[0002] Dust masks are personal respiratory protective equipment used in dusty environments. Currently, dust masks are mainly divided into two categories: disposable one-piece masks and fixed-type replaceable-filter masks. Disposable masks have a one-piece structure where the filter and mask are inseparable. Once the filter becomes clogged, the entire mask must be discarded, resulting in high consumption of consumables, high operating costs, and significant resource waste and environmental pollution. Traditional replaceable-filter masks often use flip-top or snap-on replaceable-filter structures. Replacing the filter requires disassembling the mask cover, removing and reassembling the snaps, and separating the sealing structure, making the process cumbersome and time-consuming.

[0003] Meanwhile, in existing refillable masks, the filter element is exposed during replacement, making it easy for dust and particulate matter attached to its surface to fall off and become airborne, causing secondary pollution. This can easily contaminate hands, face, and the inside of the mask, affecting hygiene and safety. Furthermore, traditional structures generally suffer from inaccurate filter element positioning and poor sealing. After installation, the filter element is prone to misalignment and air leakage, allowing dust to seep in from the sides, resulting in insufficient protective sealing. Some masks also experience loosening of the seams and aging of the seal after prolonged wear, leading to poor protective stability and making it difficult to meet the needs of long-term, high-frequency, and repeatedly replaced industrial protective applications. Summary of the Invention

[0004] This invention provides a drawer-type mobile dust mask with a replaceable filter core, which solves the technical problem of poor protective stability after filter core replacement. The filter core is concentrated and then converged at various points on the manifold itself. The manifold leads to the fluid channel. The filter device itself can filter impurities in the mask body by heating. The filter device itself can further increase the adsorption effect of the filter device by heating, thereby improving the protective stability of the mask after filter core replacement.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0006] A drawer-type portable dust mask with refillable inserts includes:

[0007] The mask itself;

[0008] A sealing structure is used to seal the mouth of the mask body. The sealing structure is made of rubber and can be bent.

[0009] Manifolds are used for fluid convergence. They are made of rubber and come into contact with the sealing structure. The manifolds concentrate the fluid at various points and then converge it again. The manifolds lead to and connect with the fluid channel.

[0010] The filter device is connected to the fluid channel, and the filter device itself can filter impurities in the mask body by heating.

[0011] After the fluid is concentrated at various points on the manifold itself, it is concentrated again. The manifold leads to the fluid channel, and the filter device itself can filter impurities in the mask body by heating.

[0012] Optionally, the sealing structure has a first sealing plate and a second sealing plate;

[0013] The first and second sealing sheets are made of rubber, and their fit together seals the mouth area of ​​the mask body.

[0014] Furthermore, the first and second sealing sheets are bonded together with double-sided adhesive, and the first and second sealing sheets come into contact with the manifold.

[0015] Optionally, the manifold has an array of guide ports, manifold channels, and collection ports.

[0016] The diversion port is used for centralized flow convergence at various points. The diversion port leads to the flow convergence channel, which is connected to the collection port.

[0017] The flow is concentrated at various points through the diversion port, the flow channel performs one convergence, and the collection port performs another convergence, so that the fluid in the fluid channel has fluid pressure.

[0018] Furthermore, a pipe channel is opened in the fluid channel, and the pipe channel is connected to the manifold.

[0019] Furthermore, the guide port, the confluence channel, and the collector port are arranged sequentially from top to bottom. The sum of the volumes of each guide port is greater than the volume of the confluence channel, and the volume of the confluence channel is greater than the volume of the collector port. This facilitates the gradual increase in fluid pressure from the guide port to the collector port after passing through the confluence channel, allowing the fluid to enter the pipe channel.

[0020] Optionally, the filtration device includes a silica gel heating element, an activated carbon granule layer, and a filter screen;

[0021] The silicone heating element is used to heat the activated carbon granule layer, which is positioned between the silicone heating element and the filter screen. The activated carbon granule layer is used to adsorb impurities in the fluid.

[0022] Furthermore, the fluid channel has a pipe channel, and the activated carbon particle layer leads to the pipe channel.

[0023] Furthermore, the filter is embedded inside the mask body to facilitate its fixation.

[0024] Furthermore, the silicone heating element extends to the outside of the mask body via an electric heating wire, and the silicone heating element itself can heat up.

[0025] The beneficial effects of this invention are:

[0026] 1. The filter device of the present invention is connected to the fluid channel. The filter device itself can filter impurities in the mask body by heating. After the impurities are concentrated and converged at various points on the manifold itself, they are concentrated and converged again. The manifold leads to the fluid channel. The filter device itself can filter impurities in the mask body by heating. The mask body has a manifold, a fluid channel and a filter device. The filter device itself is further enhanced by heating, which increases the adsorption effect of the filter device and improves the protective stability of the mask after the core is replaced.

[0027] 2. The manifold of the present invention is used for fluid convergence. The manifold is made of rubber material and is in contact with the sealing structure. The manifold concentrates the fluid at its various points and then concentrates the fluid again. The manifold leads to the fluid channel and is connected to the fluid channel, so that the fluid channel has fluid pressure. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] Example 1

[0040] like Figure 1 As shown, this embodiment provides a drawer-type mobile refillable dust mask, including: a mask body 1, ear loops 2, a sealing structure 3, a manifold 4, a fluid channel 5, and a filter device 6; the sealing structure 3, manifold 4, fluid channel 5, and filter device 6 are located inside the mask body 1, and ear loops 2 are connected to both the left and right ends of the mask body 1.

[0041] The sealing structure 3 is used to seal the mouth of the mask body 1. Since there is an opening at the upper end of the mask body 1, the upper end of the mask body 1 has an opening. The sealing structure 3 is made of rubber material and can be bent.

[0042] The manifold 4 is used for fluid convergence. The manifold 4 is made of rubber. The manifold 4 is in contact with the sealing structure 3. The manifold 4 uses its various points to converge the fluid and then converges the fluid again. The manifold 4 leads to the fluid channel 5 and is connected to the fluid channel 5. The fluid channel 5 is also made of rubber and can be bent.

[0043] The filter device 6 is connected to the fluid channel 5, and the filter device 6 itself can filter impurities in the mask body 1 by heating;

[0044] After the fluid is concentrated at various points on the manifold 4, it is concentrated again and then leads to the fluid channel 5. The filter device 6 can filter impurities in the mask body 1 by heating.

[0045] Specifically, as follows: Figure 2 As shown, the sealing structure 3 has a first sealing sheet 31 and a second sealing sheet 32, which are respectively bonded to the opening of the mask body 1. The first sealing sheet 31 and the second sealing sheet 32 ​​are made of rubber, so they can be bent. The first sealing sheet 31 and the second sealing sheet 32 ​​seal the opening of the mask body 1 by adhering to each other. The first sealing sheet 31 and the second sealing sheet 32 ​​can be bonded together with double-sided adhesive. After being bonded together with double-sided adhesive, the first sealing sheet 31 and the second sealing sheet 32 ​​seal the opening of the mask body 1. The first sealing sheet 31 and the second sealing sheet 32 ​​are in contact with the manifold 4.

[0046] The manifold 4 has an array of guide ports 41, manifold channels 42 and collection ports 43;

[0047] The guide port 41 is used for centralized flow collection at various points. The guide port 41 leads to the flow collection channel 42, and the flow collection channel 42 is connected to the collection port 43.

[0048] The fluid flows through various points via the guide port 41, then through the converging channel 42, and finally through the collecting port 43, thus giving the fluid in the fluid channel 5 pressure. Therefore, the guide port 41 facilitates the convergence of fluids at various points, connecting to the converging channel 42, which then connects to the collecting port 43, where the fluid flows again. Only then does the fluid in the fluid channel 5 gain pressure, allowing the filter device 6 to perform fluid filtration.

[0049] like Figure 3 As shown, a pipe channel 51 is opened in the fluid channel 5, and the pipe channel 51 is connected to the collection port 43.

[0050] The guide port 41, the confluence channel 42, and the collector port 43 are arranged sequentially from top to bottom. The sum of the volumes of the guide ports 41 is greater than the volume of the confluence channel 42, and the volume of the confluence channel 42 is greater than the volume of the collector port 43. This facilitates the gradual increase of fluid pressure from the guide port 41 to the collector port 43 after passing through the confluence channel 42, allowing the fluid to enter the pipe channel 51.

[0051] like Figure 4 As shown, the filter device 6 has a silicone heating element 61, an activated carbon granule layer 62, and a filter screen 63; the silicone heating element 61, the activated carbon granule layer 62, and the filter screen 63 (which may be a stainless steel mesh) are all flexible. The activated carbon granule layer 62 consists of activated carbon granules filled between the silicone heating element 61 and the filter screen 63. Figure 4 The upper, lower, front, and rear surfaces of the activated carbon granule layer 62 are all covered with a rubber material film. The left and right surfaces of the activated carbon granule layer 62 are respectively attached to the silicone heating plate 61 and the filter screen 63, which makes it easy for the activated carbon granule layer 62 to be bent.

[0052] The silicone heating pad 61 is used to heat the activated carbon granule layer 62, which is disposed between the silicone heating pad 61 and the filter screen 63. The activated carbon granule layer 62 is used to adsorb impurities in the fluid. A pipe channel 51 is opened in the fluid channel 5, and the activated carbon granule layer 62 leads to the pipe channel 51. The filter screen 63 is embedded in the mask body 1 for easy fixation.

[0053] like Figure 1 and Figure 4 As shown, the silicone heating pad 61 extends to the outside of the mask body 1 through the electric heating wire a, and the silicone heating pad 61 itself can heat up.

[0054] Example 2

[0055] Based on Example 1, the adsorption effect of activated carbon is related to temperature. When the waste gas enters the activated carbon granule layer 62, the temperature of the activated carbon granule layer 62 is controlled below 40°C. The optimal adsorption temperature of the activated carbon granule layer 62 is between 20°C and 40°C. The waste gas adsorbed by the activated carbon granule layer 62 can be radon gas flowing through the air. If the temperature is too high, not only will the waste gas not be adsorbed, but the pollutants previously adsorbed will also be released again, causing secondary pollution.

[0056] Therefore, the silicone heating element 61 is a low-power electrical component that controls the temperature of the activated carbon particle layer 62 between 20°C and 40°C.

[0057] The heating of the activated carbon granular layer 62 is divided into four stages:

[0058] Drying stage (100-150℃): Evaporation of moisture and some low-boiling-point organic matter. Energy consumption in this stage accounts for 50%-70% of the total process.

[0059] Carbonization or roasting stage (300-850℃): Heating under an inert atmosphere (such as nitrogen) causes most of the organic matter to pyrolyze, volatilize or carbonize, avoiding oxidation and burn-off of activated carbon.

[0060] Activation stage (800-950℃): Weak oxidizing gases such as water vapor and CO2 are introduced to react with residual carbon (C+H2O→CO+H2), clearing micropores and restoring adsorption performance.

[0061] Cooling and sieving stage: Rapidly cool to room temperature under inert gas protection, sieve out broken particles, and obtain regenerated activated carbon.

[0062] Therefore, the activated carbon particle layer 62 taken out from the mask body 1, after going through the drying stage, carbonization or calcination stage, activation stage, and cooling and sieving stage, has the adsorption effect of regenerated activated carbon.

[0063] Example 3

[0064] Based on Embodiment 1 and Embodiment 2, as Figure 5 As shown, at the mouth of the mask body 1, the first sealing sheet 31 and the second sealing sheet 32 ​​are opened, and the manifold 4, the fluid channel 5 and the filter device 6 are placed together inside the mask body 1. The silicone heating sheet 61 is extended to the outside of the mask body 1 through the electric heating wire a.

[0065] When the first sealing plate 31 and the second sealing plate 32 are closed, the exhaust gas inside the mask body 1 is concentrated and collected at various points through the guide port 41, the collection channel 42 is used for one collection, and the collection port 43 is used for another collection, so that the fluid leading to the fluid channel 5 has fluid pressure.

[0066] The silicone heating element 61 provides low-power heating and controls the temperature of the activated carbon granule layer 62 between 20°C and 40°C. The activated carbon granule layer 62 adsorbs the waste gas, and the filter screen 63 filters impurities in the waste gas, such as dust.

[0067] Therefore, in this embodiment, after the exhaust gas passes through the manifold 4 twice, it enters the filter device 6 through the fluid channel 5. The silicone heating element 61 heats the activated carbon granule layer 62, which can adsorb the exhaust gas. The filter screen 63 filters the impurities in the exhaust gas.

[0068] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope described in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
