Abstract
Description
Technical Field
[0001] This utility model belongs to the field of respiratory mask technology, and more specifically, relates to a low-barrier respiratory mask support. Background Technology
[0002] Industrial environments often contain a lot of harmful substances such as dust, fumes, and smoke. Therefore, workers use sealed dust masks that cover the nose and mouth to prevent or reduce airborne dust from entering the respiratory system and thus protect their lives. The filter cotton in these masks mainly adsorbs toxic and harmful particles. In existing respirators, the filter cotton is a single rectangular piece, and the adsorption efficiency mainly depends on the area of the filter cotton. Current filters usually rely on multiple layers, resulting in high breathing resistance. Therefore, a low-barrier respirator is needed. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a low-barrier breathing mask holder, which can meet the low-barrier requirements of breathing masks.
[0004] This utility model discloses a low-barrier breathing mask support, including a support base, a sealing frame, an air inlet cap, a locking buckle, and filter cotton. The support base has a hinge pin on one side and a locking groove on the other side. The air inlet cap has a hinge sleeve on one side and is hinged to the locking buckle on the other side. The support base and the air inlet cap are hinged to the hinge sleeve via the hinge pin. The end of the locking buckle that is not hinged to the air inlet cap is engaged with the locking groove, and the connection between the locking buckle and the groove can be disconnected. The support base has a filter chamber, and the filter cotton is placed inside the filter chamber.
[0005] As a further improvement of this utility model, it also includes a sealing frame, which is fastened to the outer ring of the filter chamber and connected to the support base to prevent side air from entering the human body without the filter cotton.
[0006] As a further improvement of this utility model, the filter cotton is set as a folded layer of meltblown cloth, which reduces breathing resistance, increases the filter cotton area in the same space, improves adsorption efficiency, and the folds and protrusions of the filter cotton support it in the filter chamber, so that there is no need to set support rods in the filter chamber, optimizes the support structure, and reduces breathing obstruction.
[0007] As a further improvement of this utility model, a locking post is provided on the side of the sealing frame near the support base, and the support base is provided with a matching locking groove. When the sealing frame is snapped into the support base, the locking post fits into the locking groove, thereby improving the stability of the breathing mask.
[0008] As a further improvement of this utility model, the support base includes a connecting ring, which is snapped into the breathing mask.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: the filter cotton is set as a folded layer of meltblown cloth, which reduces breathing resistance; the filter cotton area in the same space is increased, which improves adsorption efficiency; the pleats and protrusions of the filter cotton are supported in the filter chamber, so that there is no need to set support rods in the filter chamber, which optimizes the support structure and reduces breathing obstruction; the sealing frame is snapped onto the outer ring of the filter chamber and engages with the support, preventing side air from entering the human body without the filter cotton; after the sealing frame is snapped onto the support, the locking post fits into the locking groove, which improves the stability of the breathing mask.

[0017] Support base 1; hinge pin 11; locking groove 12; filter chamber 13; slot 14; connecting ring 15; sealing frame 2; locking post 21; air inlet cover 3; hinge sleeve 31; locking buckle 4; filter cotton 5; breathing mask 6. Detailed Implementation
[0018] Specific Implementation Example 1: Please refer to Figures 1-6 This utility model relates to a low-barrier breathing mask support, including a support base 1, a sealing frame 2, an air inlet cover 3, a locking buckle 4, and a filter cotton 5. The support base 1 has a hinge pin 11 on one side and a locking groove 12 on the other side. The air inlet cover 3 has a hinge sleeve 31 on one side and is hinged to the locking buckle 4 on the other side. The support base 1 and the air inlet cover 3 are hinged to the hinge sleeve 31 through the hinge pin 11. The end of the locking buckle 4 that is not hinged to the air inlet cover 3 is engaged with the locking groove 12, and the connection between the locking buckle 4 and the groove 14 can be disconnected. The support base 1 has a filter chamber 13, and the filter cotton 5 is placed in the filter chamber 13.
[0019] In a further embodiment, such as Figure 2As shown, it also includes a sealing frame 2, which is fastened to the outer ring of the filter chamber 13 and connected to the support base 1 to prevent side air from entering the human body without the filter cotton 5.
[0020] In a further embodiment, such as Figure 5 As shown, the filter cotton 5 is a folded layer of meltblown fabric, which reduces breathing resistance, increases the area of the filter cotton 5 in the same space, and improves adsorption efficiency. The folds and protrusions of the filter cotton 5 are supported in the filter chamber 13, so that no support rod is needed in the filter chamber 13, thus optimizing the structure of the support seat 1 and reducing breathing obstruction.
[0021] In a further embodiment, such as Figure 3 and Figure 4 As shown, the sealing frame 2 has a locking post 21 on the side near the support base 1, and the support base 1 has a matching locking groove 14. When the sealing frame 2 is snapped into the support base 1, the locking post 21 fits into the locking groove 14, improving the stability of the breathing mask 6.
[0022] In a further embodiment, such as Figure 2 and Figure 6 As shown, the support base 1 includes a connecting ring 15, which is snapped into the breathing mask 6.
[0023] When in use, move the locking buckle 4 to disconnect the locking buckle 4 from the locking groove 12, then rotate the air inlet cover 3 to expose the filter chamber 13. Place the filter cotton 5 into the filter chamber 13 and check that the filter cotton 5 is not squeezed or deformed, ensuring that the filter cotton 5 can support itself. Then, fit the locking post 21 into the locking groove 14 to ensure side sealing. After placing the filter cotton 5, rotate the air inlet cover 3 to close the filter chamber 13. Take out the breathing mask 6 and connect the breathing mask 6 to the support base 1 through the connecting ring 15. Then put on the breathing mask 6. The breathing mask 6 will start filtering as the person breathes.
