To combine Fig. 2～Fig. 5 to specify the air-breathing and expiration principle of the mouth mask 100 of the utility model below.
When air-breathing; Fresh air flow in the said air-breathing through hole 11 through air intake duct 31, and is as shown in Figure 2, and in said air-breathing through hole 11; Under the gas pressure of the fresh air that sucks; Said first diaphragm seal 43 is pressed off and is opened first opening 410 on said first stator 41, forms conducting states thereby make in the mouth mask in the external said air-breathing through hole 11, and this moment, said first diaphragm seal 43 was in first release position; Fresh air can enter to mouth mask inboard 102 from the arrow A direction via first opening 410.And meanwhile; As shown in Figure 3; 53 of second diaphragm seals in the expiration through hole 12 inwardly are pressed on said second stator 51 under the gas pressure of the fresh air that sucks; Thereby seal up second opening 510 on said second stator 51, make in the mouth mask and form closed condition in the external said expiration through hole 12, this moment, said second diaphragm seal 53 was in second sealing station.
And when exhaling; As shown in Figure 4; The carbon dioxide that the people breathes out is outwards breathed out via expiration through hole 12, and second diaphragm seal 53 in this moment said expiration through hole 12 is exhaled under the power effect away from said second stator 51 the carbon dioxide of breathing out, thereby opens second opening 510 on said second stator 51; Make in the mouth mask and form conducting state in the external said expiration through hole 12; This moment, said second diaphragm seal 53 was in second release position, and the carbon dioxide of exhalation can be breathed out to the mouth mask outside 101 via second opening 510 from the arrow B direction.And meanwhile; As shown in Figure 5; 43 of first diaphragm seals in the air-breathing through hole 11 outwards are pressed on said first stator 41 under the gas pressure of the carbon dioxide of breathing out; Thereby seal up first opening 410 on said first stator 41, make in the mouth mask and form closed condition in the external said air-breathing through hole 11, this moment, said first diaphragm seal 43 was in first sealing station.
So, when the painter carried out the mopping operation in the operating room, because air-breathing through hole 11 conductings and air intake duct 31 are to be communicated to outdoor fresh air when air-breathing, and expiration through hole 12 was closed, so the workman can be through the outer fresh air of air intake duct 31 suction chambers; And air-breathing through hole 11 is closed and air intake duct 31 is to be communicated to outdoor fresh air when exhaling, and 12 conductings of expiration through hole, so the workman can breathe out the carbon dioxide of breathing out through exhaust tube 32.Like this, the workman promptly can breathe outdoor fresh air at the indoor mouth mask that has on the utility model, and indoor showy paint particle also can not be inhaled into, thereby can guarantee that the workman's is healthy.
In the utility model, please return with reference to figure 1 protuberance 13 that the mouth and nose that said mouth mask 100 preferably has outside protrusion and human body are suitable.In addition, said mouth mask 100 also comprises the sticking part 14 being processed and can be fitted tightly with human face by flexible material (for example flexible plastic, rubber etc.), in order to prevent that further paint particle is via in mouth mask and the human face contact position entering mouth mask.
In the utility model; Said air intake duct 31, exhaust tube 32 can have multiple with the connected mode of said air-breathing through hole 11, expiration through hole 12; For example can be integrally formed; Also can be that said air-breathing through hole 11 and said expiration through hole 12 are extended to form an extension (not shown) towards the said mouth mask outside 101 respectively; And the other end of said air intake duct 31 and said exhaust tube 32 is connected through said extension respectively, thereby realize and being communicated with of said air-breathing through hole 11 and said expiration through hole 12.And, can also clamp through detachable clamp connection with said extension junction at the other end of said air intake duct and said exhaust tube and to be connected, for example clip etc.In addition, the mouth mask of the utility model also is not limited to be applied in the mopping operation, and it also can be applicable to pharmacy etc. and need avoid sucking in the production operation process of deleterious particle.
Certainly; The utility model also can have other various embodiments; Under the situation that does not deviate from the utility model spirit and essence thereof; Those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
