The working principle of the invention is as follows: when the air conveying bag 106 is extruded, the internal pressure of the air conveying bag 106 is increased, and gas can jack up the non-return plate 124 on the air outlet pipe 105 and is discharged from the air outlet pipe 105 to enter the mask for a user to breathe.
When the air conveying bag 106 is extruded, the non-return plate 124 on the air inlet pipe 101 is closed, when the extrusion rod 113 releases the extrusion of the air conveying bag 106, the pressure inside the air conveying bag 106 is reduced, the air inlet pipe 101 is communicated with the outside, the air outside can extrude the non-return plate 124 on the air inlet pipe 101 into the air conveying bag 106, and when the air conveying bag 106 is extruded again, the air in the air conveying bag 106 is discharged for the breathing of a user wearing the mask.
The distance between the cam 112 and the air delivery bag 106 can be adjusted, when the cam 112 is close to the air delivery bag 106, the smaller the degree of extruding the air delivery bag 106 is, the smaller the amount of air discharged by the air delivery bag 106 is, when the cam 112 is far away from the air delivery bag 106, the larger the degree of extruding the air delivery bag 106 is, the larger the amount of air discharged by the air delivery bag 106 is, because the inclined main seat 123 is inclined, when the cam 112 is close to the air delivery bag 106, the cam 112 is far away from the rotating fulcrum of the extruding rod 113, namely the inclined seat shaft 120; the adjusting motor 121 is started to drive the adjusting screw rod 122 to rotate, the adjusting screw rod 122 drives the adjusting carriage 110 to slide, the adjusting carriage 110 drives the adjusting rod 118, the adjusting sliding block 111 and the cam 112 to slide, and the distance between the cam 112 and the air conveying bag 106 is adjusted, and the right connecting rod 116 is rotationally connected with the left connecting rod 117, so that the sliding of the adjusting rod 118 is not influenced.
The gas cylinders 128 are respectively filled with the required gas through the gas mixing pipes 104, when the driving rod 109 rotates, the large incomplete gear 133 is driven to rotate, the reciprocating driving gear 131 is driven to rotate under the action of the belt assembly, the reciprocating driving gear 131 and the reciprocating driven gear 136 form gear matching, the reciprocating incomplete gear 135 rotates, the large incomplete gear 133 firstly meshes with the reset long rack 157 when rotating, the reset long rack 157 is driven to slide, after the reset long rack 157 slides a certain distance away from the slider motor 146, the reciprocating incomplete gear 135 meshes with the reciprocating long rack 143 again to drive the reciprocating long rack 143 to slide, the reciprocating incomplete gear 131 is close to the slider motor 146, and the spring on the reciprocating fixed rod 144 is compressed.
When the reciprocating long rack 143 slides, the connecting plate 140 is driven to slide, the connecting plate 140 drives the pawl 142 to slide, the pawl 142 slides to be close to the special-shaped groove plate 137 and slides on the surface of the special-shaped groove plate 137, and the initial state of the special-shaped groove plate 137 covers the upper portion of the groove of the piston rod 134, so that when the pawl 142 slides, the piston rod 134 cannot be driven to slide.
Due to the arrangement of the reciprocating incomplete gear 135, when the tooth-shaped structure on the reciprocating incomplete gear 135 is not meshed with the reciprocating long rack 143, the reciprocating long rack 143 is rebounded and reset under the action of the spring on the reciprocating fixed rod 144, and the pawl 142 is reset.
When the long reset rack 157 slides, the reset head 155, the small reset rod 151, the fixed block 153 and the spring piece 152 are driven to slide together, the spring piece 152 firstly slides in the upper slideway 150, the long reset spring 154 is compressed, the long reset rack 157 slides, the spring piece 152 is clamped on the clamping groove plate 148, the long reset rack 157 is prevented from rebounding under the action of the long reset rack 154, under the continuous meshing of the large incomplete gear 133 and the long reset rack 157, finally the small reset rod 151 slides into a special-shaped groove of the special-shaped groove plate 137 to drive the special-shaped groove plate 137 to slide, the special-shaped groove plate 137 is pulled to release the coverage of the groove of the piston rod 134, then when the pawl 142 slides again, the pawl 142 is matched with the groove on the piston rod 134 to drive the piston rod 134 to slide, and gas in the gas storage bottle 128 is extruded.
The gas cylinder 128 is provided with a gas mixture valve 159, when the piston rod 134 slides, the gas presses the gas mixture valve 159 to slide, the gas mixture valve 159 slides for a certain distance under the action of the gas mixture spring 160, the communication between the gas cylinder 128 and the hose 127 is opened, and the gas enters the gas outlet pipe 105 from the hose 127, and is mixed and delivered to a mask user.
When the fixed block 153 continues to slide along the reset long rack 157, the spring piece 152 enters the lower slide 149 from the inclined slide groove far away from the slide motor 146 (the inclined slide groove is one of the inclined slide grooves at the two ends of the upper slide 150 and the lower slide 149 and far away from one end of the slide motor 146), the spring piece 152 loses the blocking, the reset long spring 154 returns to rebound to drive the reset long rack 157 to reset, when the spring piece 152 passes through the reset slide block 158, the spring piece 152 slides into the upper slide 150 again from the inclined slide groove between the two clamping groove plates 148 to reset, the position of the reset slide block 158 is adjusted to start the slide motor 146 to drive the slide screw 147 to rotate, the reset slide block 158 slides to the inclined slide groove between every two clamping groove plates 148, and the spring piece 152 resets.
The position of the reset slider 158 determines the time for the spring 152 to rebound and reset, if the reset slider 158 is close to the slider motor 146, the time for the spring 152 to reset is long, then the time for the reset small rod 151 to open the special-shaped groove plate 137 is long, the sliding frequency of the piston rod 134 is slow, the gas transmission frequency is slow, if the reset slider 158 is far away from the slider motor 146, the time for the spring 152 to reset is short, then the time for the reset small rod 151 to open the special-shaped groove plate 137 is shorter, the sliding frequency of the piston rod 134 is fast, and the gas transmission frequency is fast.
When the reset lever 151 resets, the special-shaped groove plate 137 is driven to reset.
After the piston rod 134 is once slid and stopped, the gas mixture valve 159 is reset by the gas mixture spring 160, and the gas mixture valve 159 disconnects the gas cylinder 128 from the hose 127, so that the gas cannot be discharged.
When the pawl 142 drives the piston rod 134 to slide, the gas mixture adjusting plate 138 can adjust the sliding distance of the piston rod 134, the gas mixture adjusting cylinder 139 is started to drive the gas mixture adjusting plate 138 to slide, when the gas mixture adjusting plate 138 is closer to the special-shaped groove plate 137, the pawl 142 is matched with the groove of the piston rod 134, the sliding distance of the piston rod 134 is driven to be shorter, the exhaust amount is smaller, when the gas mixture adjusting plate 138 is farther from the special-shaped groove plate 137, the pawl 142 is matched with the groove of the piston rod 134, the sliding distance of the piston rod 134 is driven to be longer, and the exhaust amount is larger.
The invention is applicable to the prior art where it is not described.
