technical field

The utility model relates to the field of mask gas filtration, in particular to a liquid filter mask.

Background technique

At present, the pollution of the atmospheric environment is intensifying, and the frequency of smog weather is high and the duration is long. The attached particles in the air enter the human body with the respiratory system and seriously endanger human health. Most of the filter elements of existing masks on the market are filtered by solid activated carbon or gauze. Although the mask or mask adopts the method of liquid filtration, the filter element does not have the function of taking out and replacing, which is not convenient for daily mask use and cleaning, and meets the needs of different environments.

CN103504634 provides a mask for protecting against strong acid damage, including a mask body, ear straps, nose clips (3), and protective strips. The mask body has three layers, the outer layer is an acid-absorbing layer soaked with alkaline liquid, and the middle layer is waterproof and breathable non-woven Cloth layer, the inner layer is activated carbon absorption layer. The beneficial effect is that the acid absorption layer soaked with alkaline liquid on the outer layer can effectively prevent the inhalation of acid gas, and the active carbon absorption layer with strong adsorption capacity can effectively absorb other harmful gases and substances in the air. CN104207375 provides a mask for blocking PM2.5 particles, including a mask body, and a liquid adsorption layer for blocking PM2.5 particles is arranged outside the mask body. By setting a detachable liquid adsorption layer on the outside of the mask, PM2.5 particles can be effectively blocked. The structure is simple, the price is cheap, and it has good ventilation effect. It has a wide range of applications. The mask body has a waterproof and breathable fabric layer, which can effectively block liquid adsorption. A large amount of moisture in the layer is inhaled by the human body. These two kinds of liquid adsorption are attached to the mask body as a layer, and it is not considered that when wearing, due to the weight of the liquid itself, the liquid is difficult to distribute evenly in the liquid filter layer, and it can only be at the bottom, resulting in entering from the middle and upper part of the mask. The gas cannot be filtered, which directly leads to poor filtering effect.

The utility model is described in further detail below through specific embodiments in conjunction with the accompanying drawings.

Considering the problem that the current masks that adopt the liquid filtration method cannot completely filter or do not filter the inhaled gas, resulting in extremely low gas purity, the utility model provides a liquid filter mask.

The liquid filtering mask includes: a mask body, the mask body includes an outer layer, an inner layer, and a filter element; the edges of the outer layer and the inner layer are connected to form a bag structure, and the filter element is placed in the bag structure; the filter element is filled with filtrate, and an air inlet is set and the air outlet, the air inlet and the air outlet are all connected with the filtrate; the mask body is provided with an air inlet and an exhalation hole, the air inlet is connected with the air inlet, and the exhalation hole is connected with the air outlet.

The filter element is placed in the bag structure where the inner layer and the outer layer are spliced, and the filtrate is placed in the filter element, and the air inlet and the air outlet connected to the filtrate are set; the gas enters the filtrate smoothly and is discharged smoothly after filtration; however, the mask body has The air intake hole and the exhalation hole are specially set, the air intake hole is connected to the air inlet, and the exhalation hole is connected to the air outlet. The external air enters the air inlet of the filter element through the air inlet, and then the filtered liquid is filtered. After the gas is discharged from the gas outlet, it enters the exhalation hole and is breathed. This structure stipulates the filtering path before the outside air is inhaled by the human body, and the situation that unfiltered air is not directly inhaled will not occur. The filtering effect is improved and the purity of the breathed air is improved.

Next, a detailed description of the liquid filtering mask:

A liquid filtering mask, as shown in Figures 1-3, includes: a mask body 1, which basically refers to the part that covers the face. Specifically, the mask body 1 includes an outer layer 13, an inner layer 17, and a filter element 2; the outer layer 13 is in contact with the outside air, the inner layer 17 is in contact with people's skin, and the filter element 2 plays a filtering effect. The edges of the outer layer 13 and the inner layer 17 are connected to form a bag structure, and the filter element 2 is placed in the bag structure, and the filter element 2 is between the inner and outer layers. The position in the mask is also more stable. Filtrate 28 is contained in the filter element 2, and the filtrate 28 filters the outside air entering the mouth mask. The filter element 2 is provided with an air inlet 24 and an air outlet, and the air inlet 24 and the air outlet are connected with the filtrate 28, the gas enters from the air inlet 24 and reaches the filtrate 28, and the filtered gas is discharged from the filtrate 28 through the air outlet . In order to further standardize the entry and discharge channels of gas, the mask body 1 is provided with an air inlet 14 and an exhalation hole, the air inlet 14 is connected with the air inlet 24, and the exhalation hole is connected with the air outlet. External air enters the mask from the air inlet 14, and then enters from the air inlet 24; after the filtered gas is discharged from the air outlet, it directly enters the exhalation hole, and is breathed afterwards. The gas path is fixed and unique, and the gas breathed into the human body must pass through this filtering process, and the filtering effect is excellent.

The inner layer 17 and the outer layer 13 of the mouth mask body mainly adopt pure cotton material, which is comfortable to wear and breathable. The filter element 2 housing mainly adopts non-toxic plastic material, which is small in size and light in weight and is easy to assemble.

In order to improve the smoothness of breathing, a plurality of exhalation holes, or two holes with larger apertures can be arranged. No matter which method is used, the exhalation holes must be evenly distributed on the mask surface and symmetrical along the central axis to improve the uniformity and symmetry of exhalation.

Considering the timeliness of liquid filtration, after many times of filtration, the efficiency of liquid filtration will be weakened and needs to be replaced. In order to facilitate replacement, the bag structure formed by the inner and outer layers 13 is provided with an opening, and the filter element 2 can be put into the bag from the opening. Bag structure or removed from the bag structure.

Since the filter element 2 can be taken out freely, the position of the filter element 2 needs to be further fixed, and the problem of the filter element 2 automatically sliding out of the bag structure needs to be considered. Therefore, the opening is provided with a closure. After the filter element 2 is placed in the bag structure, the opening is closed.

There are many ways and forms of the above-mentioned closure, as long as the purpose of closing the opening is achieved, such as zipper 16, sticky buckle, or snap-in sticker. An appropriate method can be appropriately selected in different technical solutions.

In order to further save costs and materials, in addition to replacing the filter element 2, a new replacement method is also designed in some other technical solutions, that is, replacing the filtrate 28. Based on this idea, a liquid port is provided on the side wall of the filter element 2, and the filtrate 28 can enter or discharge from the liquid port. The liquid port is recommended to be installed above the liquid surface to avoid liquid leakage. In the process of adding liquid, in order to observe the state of the filtrate 28 conveniently, a transparent scale is set on the side wall of the filter element 2 . The added amount of the filtrate 28 can be observed from the transparent scale, so that it is difficult to grasp the added amount of the filtrate 28 . Moreover, the filtering effects of different filtrates 28 are quite different, and the user can select a suitable filtrate 28 to realize air filtration according to the air quality. Improve the selectivity of the filtrate 28 and expand the scope of use.

The particles attached to the air will dissolve in it when passing through the filter liquid 28, so as to ensure that the air will become clean after being filtered by the liquid. The filter liquid 28 contains a large amount of gas and particles. The gas reduces the effect and efficiency of gas filtration. A one-way valve is set in the exhalation hole. When the gas enters the human body from the mask, it opens, and the gas exhaled by the human body cannot pass through the one-way valve. This can play a role in preventing backwater.

In order to more fully send the gas entering from the outside into the filtrate 28 to be filtered, the path of the gas entering the mask and before entering the filtrate has been designed in more detail. One end of 25 communicates with the air inlet 24, and the other end extends into the filtrate 28. In this way, the amount of gas filtered by the filtrate 28 can be increased. Certainly, the air inlet pipe 25 protrudes below the liquid level of the filtrate 28, and a certain gap needs to be reserved with the bottom surface to facilitate gas circulation.

The filter element 2 is a bag-shaped structure, and its lower part holds the filtrate 28. After the gas is filtered in the filtrate 28, the interior will contain a large amount of gas and particles, and some air bubbles will be generated during the breathing process. The plate 26 and the partition 26 are provided with a plurality of ventilation holes through which the filtered gas passes. The partition 26 can prevent the accumulation of air bubbles, and can also buffer the fluctuation of the liquid during exercise and improve the smoothness of breathing.

In a specific design, the main frame of the filter element 2 can be divided into a front casing and a rear casing, and a closed cavity is formed between the front casing and the rear casing, and liquid is stored in the cavity.

The gas discharged from the filtrate 28 will contain more liquid components. As the gas rises, the liquid components will fall and evaporate. Therefore, an air outlet pipe 27 is arranged in the filter element 2, and one end of the air outlet pipe 27 communicates with the air outlet. One end is above the partition 26 . The gas outlet pipe 27 absorbs gas from the dividing plate 26, and gradually sends it into the gas outlet, which prolongs and fixes the path of the filtered gas.

In order to prevent the phenomenon of returning water, the air outlet pipe 27 is provided with one or more bends, on the one hand to circulate the gas, and on the other hand to prevent the liquid from entering the air outlet.

Cooperate with mask body to wear on people's face, as shown in Figure 3, the both sides of mask body 1 are equipped with adjustment belt 11, and design adjustment buckle 12 is convenient for the wearer to adjust on the adjustment belt 11, to adapt to the needs of different face shapes. A nose clip 15 is arranged in the middle area of the upper edge of the mask body, which is processed by plastic material, which is convenient for shaping and can better fit the face shape when worn.

The advantages of this mask are small size, light weight, and easy daily wear; the filter cavity is filled with liquid, which can filter particles, dust, harmful gases, and bacteria in the air well; the filter element can be removed and replaced, which is convenient for daily cleaning of the mask; The translucent scale design of the filter element is convenient for filtrate replacement, and the volume of filtrate injected can also be adjusted according to the need for ventilation; the one-way ventilation valve can effectively solve the breathing permeability of the mask, reduce breathing resistance, and solve the stuffiness when wearing most masks Feeling; using different liquids also has the functions of disinfection and sterilization to ensure the health of the respiratory tract.

The above are only preferred embodiments of the utility model, and are not intended to limit the utility model.
