[0003] The respiratory protective equipment we commonly see in the market has a good effect on health protection, but it is sultry when worn in summer, and when worn in winter, the exhaled air is easy to fog the glasses. If it is a respiratory mask, the hot a...

Abstract

The invention relates to an air filtering device, in particular to an air filtering nose mask. By the adoption of the air filtering nose mask, a user is unlikely to feel stuffy when wearing the air filtering nose mask. In order to further improve the comfort, the attractiveness, the practicability and the like of respiratory protective equipment, the air filtering nose mask comprises shell halves, a front shell, air filtering assemblies and a sealed air channel assembly. A cavity is formed between the front shell and the shell halves. The air filtering assemblies are arranged in the cavity. Vent holes are formed in the shell halves. The vent holes communicate with the air filtering assemblies. The air filtering assemblies communicate with the sealed air channel assembly. By the adoption of the filtering nose mask, the phenomenon that the user feels stuffy when wearing a nose mask is avoided through the shell half design; in addition, the user does not feel stuffy when wearing the filtering nose mask in summer; and the attractiveness is further improved.

Example Embodiment

[0028] Such as figure 1 , 2 As shown in Figure 3, a filter nose mask includes a half shell 1, a front shell 7, an air filter assembly 3 and a closed air channel assembly. A cavity is formed between the front shell 7 and the half shell 1, and the cavity An air filter assembly 3 is provided, a vent hole 2 is opened on the half shell 1, the vent hole 2 is in communication with the air filter assembly 3, and the air filter assembly 3 is in communication with a closed air channel assembly. There is a closed air channel between the back of the half shell and the face, creating a certain distance, so it will not feel stuffy when worn. The half shell and the air filter assembly can be a combination of two air filter devices arranged symmetrically Such as figure 1 , It can also be a symmetrical air filter device Such as figure 2 .

[0029] Such as Figure 4 As shown, the airtight air channel assembly includes a support, a movably inserted nose tube 8, a short tube 9, and a regulating tube 14. The nose tube 8 is connected to the short tube 9, and the short tube 9 is connected to the regulating tube 14, and the regulating tube 14 is in communication with the air filter assembly 3; the supporting member includes two short pipes 9 arranged oppositely and connected into a symmetrical body by a connecting member 10. The two short pipes 9 are respectively connected with a fixing member 11, and one end of the fixing member 11 is provided There are hanging ears 12 which are connected to the hanging rope 13.

[0030] The air filter assembly 3 includes a filter sleeve 12 and a filter sleeve holder 15. The filter sleeve holder 15 is provided with a filter sleeve 12, wherein the filter sleeve 12 is a bag-like structure made of filter material. The filter material can be filter cotton.

[0031] Such as Picture 9 As shown, preferably, the filter cover bag holder 15 includes a fence structure composed of a plurality of thin-walled fence pieces 24 with parallel ends, and a sealing ring 26 fixed at the bottom of the periphery of the fence-like structure. An air flow passage opening I25 is formed between the gap between the sieve and the sealing ring; the filter bag 12 is inserted from the top of the filter bag holder, the edge of the filter bag bag mouth is flush with the edge of the filter bag holder end, and the filter bag bag The inner edge of the mouth coincides with the sealing ring I26.

[0032] Such as Figure 8 As shown, preferably, the filter cover bag holder includes a corrugated partition plate 20, a sealing ring II19 fixed at the bottom end of the corrugated partition wall, and an air flow channel port II18. The filter cover bag 12 is from the top of the filter cover bag holder Set in, the edge of the filter cover bag mouth is flush with the edge of the end of the filter cover bag holder, and the inner edge of the filter cover bag mouth matches the sealing ring II19.

[0033] A nose accommodating groove 4 is provided in the middle of the back of the half-shell, and the ventilation holes 2 are symmetrically opened on the two side walls of the nose accommodating groove 4.

[0034] Such as Picture 10 As shown, the half shell 1 and the front shell 7 are buckled correspondingly to form a cavity, and the front shell 7 is provided with a ventilation hole 21.

[0035] The front surface of the front housing 7 is provided with a decorative layer.

[0036] Such as Figure 5 As shown, a vent tube 17 is connected between the airtight air channel assembly and the air filter assembly.

[0037] A shielding baffle is arranged in front of the airtight air channel assembly, and the outer surface of the shielding baffle is provided with a decorative layer.

[0038] In the case of increasing the filter area to reduce the breathing resistance, the volume and weight of the nasal filter mask will increase. If worn, it will bring load-bearing burden and affect comfort; while the airtight air channel assembly and the ventilation tube 17 are extended Extend the combination of the air filter assembly, the half shell and the front shell to a certain part of the human body, and the vent 2 can be arranged on the side or back of the combination ( Figure 5 ), this method is also a method of transferring volume and weight.

[0039] The combination of air filter assembly, half shell and front shell extends to a certain part of the human body. The front of the airtight air channel assembly is provided with a shielding plate 16 in order to cover unsightly places to wear. In order to enhance the aesthetics, a decorative layer is added to the outer surface of the shielding plate. The decoration layer can be decorated with various shapes, characters, patterns and the like.
