The operation and use process of device of the present invention is as follows:

When the device is in a natural state, the air flow channel of the device is in a closed state, that is, before the pressure applying slide 2 exerts pressure on the rotating air guide 3, the positioning slide of the rotating air guide 3 of the rotating air guide 3 The block 33 is located in the first positioning chute 11 on the inner wall of the chute shell 1, and the pressure-bearing inclined sliding surface 34 on one end surface of the positioning slider 33 of the rotary air guide is in contact with the pressure-applying sliding surface. The pressure slanting surface 23 on the opening end face of the part 2 matches; when a cigarette filter is inserted into the cigarette filter accommodating cavity 18 of the chute shell part 1 and inserted in place, that is, the cigarette filter The end surface is in contact with the non-opening end surface of the pressing sliding member 2, and pushes the cigarette filter axially inward in the cigarette filter accommodating chamber 18, and the pushing force is transmitted to the cigarette filter through the cigarette filter. The pressure-applying slider 2, the pressure-applying slanted sliding surface 23 of the pressure-applying slider 2 exerts pressure on the end surface of the rotating air-guiding piece positioning slider 33 on the rotating air-guiding piece 3 The inclined sliding surface 34 exerts pressure, and the pressure is perpendicular to the pressure-bearing inclined sliding surface 34, but when the rotating air guide 3 is not separated from the first positioning chute 11 on the inner wall of the chute shell 1, Both the pressing sliding member 2 and the rotating air guiding member 3 can only move axially in the chute shell member 1 (the spring 5 is gradually compressed during this process), and the The air guide holes 31 of the rotating air guide member 3 and the air guide holes 41 of the fixed air guide member 4 are not in the opposite state, and the air flow channel is not connected, that is, the air flow channel is closed; When the pressure-applying slanting surface 23 of the pressure-applying sliding member 2 continues to press on the pressure-receiving slanting surface 34 until the rotating air guide 3 is separated from the inner wall of the chute shell 1 in the axial direction After the first positioning chute 11, the positioning slider 33 of the rotary air guide is no longer restricted by the first positioning chute 11, and the pressure-applying inclined sliding surface 23 continues to slide axially. Apply pressure to the pressure-bearing inclined sliding surface 34, the pressure is perpendicular to the pressure-bearing inclined sliding surface 34, and the rotating air guide 3 is axially supported by the fixed air guide 4 and cannot continue Axial movement, so under the above pressure, the rotating air guide 3 rotates in the circumferential direction, that is, the pressure-bearing inclined sliding surface 34 rotates circumferentially along the first inclined sliding surface 14 until it rotates to the the higher side 151 of the second inclined sliding surface 15 (because the axial depth of the second positioning chute 12 is deeper than that of the first positioning chute 11 in the axial direction The depth should be small, so when the pressure-bearing inclined sliding surface 34 rotates in the circumferential direction to the higher side 151 of the second inclined sliding surface, it is stuck, and the higher side 151 of the second inclined sliding surface acts as a limit function), so as to realize that the pressure-bearing inclined sliding surface 34 of the rotating air guiding member 3 is in contact with the inclined sliding surface 14 on the inner wall of the chute shell 1 and slides along the inclined sliding surface 14 in place (this process relies on the elastic force of the spring 5 to restore the original shape, and the pressure-bearing inclined sliding surface 34 of the rotating air guide 3 slides along the inclined sliding surface 14 on the inner wall of the chute shell 1 Among them, the movement state of the rotating air guide 3 is axial movement and circumferential movement compound movement of rotation), after the rotating air guiding member 3 rotates at a certain angle (for example, 45 degrees), the air guiding hole 31 of the rotating air guiding member on the rotating air guiding member 3 and the fixed air guiding The air guide hole 41 of the fixed air guide member on the member 4 is in an opposite state, and the air flow passage is connected.

When the device is in the working state, that is, the cigarette filter is in the cigarette filter accommodating chamber 18 of the chute shell 1, and the airflow channel of the device is in an open state, at this time the rotating air guide 3 of the The pressure-bearing inclined sliding surface 34 is located on the inclined sliding surface 14 on the inner wall of the chute shell 1, when the cigarette filter is pushed axially inward in the cigarette filter receiving chamber 18 , the push force is transmitted to the pressure-applying slide 2 through the cigarette filter, and the pressure-applying inclined sliding surface 23 of the press-applying slide 2 is opposite to the rotating air-guiding piece on the rotating air-guiding piece 3 The pressure-bearing inclined sliding surface 34 on one end surface of the positioning slider 33 exerts pressure, and the pressure-bearing inclined sliding surface 34 moves axially along the higher side 151 of the second inclined sliding surface. Before the second inclined sliding surface 15 on the inner wall of the chute shell 1 contacts, both the pressing slide 2 and the rotating air guide 3 move axially in the chute shell 1, and During the process, the air guide holes 31 of the rotating air guide member 3 and the air guide holes 41 of the fixed air guide member 4 are in the opposite state, and the airflow channel is in the communicating state. When the pressure-applying inclined-sliding surface 23 continues to apply pressure to the pressure-bearing inclined-sliding surface 34, the higher side 341 of the pressure-bearing inclined-sliding surface 34 and the inner wall of the chute shell 1 In the process just before the higher side 151 of the second inclined sliding surface 15 on the second inclined sliding surface contacts, the rotating air guiding part 3 and the pressing sliding part 2 are both in the chute shell part 1 to do axial sliding. Afterwards, when the pressure-applying slide 2 continues to slide axially through the pressure-applying slanting surface 23 to apply pressure to the pressure-receiving slanting surface 34 , since the rotating air guide 3 is in the axial direction as a whole, It is also supported by the fixed air guide 4 and cannot continue to move axially. Therefore, under the pressure exerted by the above-mentioned pressure-applying inclined sliding surface 23 on the pressure-bearing inclined sliding surface 34, the rotating air guiding member 3 again undergoes circumferential movement. Rotate, so that the pressure-bearing inclined sliding surface 34 of the rotating air guide 3 is in contact with the inclined sliding surface 15 on the inner wall of the chute shell 1 and moves along the first sliding surface under the spring restoring force. The two inclined sliding surfaces 15 rotate and slide until the positioning slide block 33 of the rotating air guide 3 on the rotating air guide 3 slides back to the first positioning chute 11 on the inner wall of the chute shell 1 (this process relies on the elastic force of the spring 5 to restore the original shape, the pressure-bearing inclined sliding surface 34 of the rotating air guide 3 slides along the inclined sliding surface 15 on the inner wall of the chute shell 1 Among them, the motion state of the rotary air guide 3 is a compound motion of axial movement and circumferential rotation), and the positioning slider 33 of the rotary air guide 3 on the rotary air guide 3 slides down into the chute The first positioning chute 11 on the inner wall of the shell 1 is restricted and can only move axially. Sliding surface 23 matches. In the above process, due to the rotation of the rotating air guiding element 3 again at a certain angle (for example, 45 degrees), the air guiding hole 31 of the rotating air guiding element 3 on the rotating air guiding element 3 is connected to the fixed air guiding element 4. The air guide hole 41 of the fixed air guide is in a non-opposite state, the air flow channel is not connected, and the device returns to a natural state, that is, the air flow channel of the device is in a closed state.

Beneficial effects of the present invention:

Aiming at the shortcomings of existing cigarette holders and electronic cigarette airflow channels, the present invention provides a device that automatically closes the airflow channel when the cigarette holder or electronic cigarette is not in use, and automatically opens/closes the airflow channel by inserting a cigarette when it needs to be used. This can not only save the volatile substances inside more effectively, but also allow consumers to open and close the airflow channel more conveniently when needed, effectively improving the experience of consumers.

In a preferred embodiment of the present invention, the device of the present invention is not only used on a cigarette holder or an electronic cigarette, but can be used as an automatic opening and closing device for any airflow channel.

The operation and use process of device of the present invention is as follows:

When the device is in a natural state, the air flow channel of the device is in a closed state, that is, before the pressure applying slide 2 exerts pressure on the rotating air guide 3, the positioning slide of the rotating air guide 3 of the rotating air guide 3 The block 33 is located in the first positioning chute 11 on the inner wall of the chute shell 1, and the pressure-bearing inclined sliding surface 34 on one end surface of the positioning slider 33 of the rotary air guide is in contact with the pressure-applying sliding surface. The pressure slanting surface 23 on the opening end face of the part 2 matches; when a cigarette filter is inserted into the cigarette filter accommodating cavity 18 of the chute shell part 1 and inserted in place, that is, the cigarette filter The end surface is in contact with the non-opening end surface of the pressing sliding member 2, and pushes the cigarette filter axially inward in the cigarette filter accommodating chamber 18, and the pushing force is transmitted to the cigarette filter through the cigarette filter. The pressure-applying slider 2, the pressure-applying slanted sliding surface 23 of the pressure-applying slider 2 exerts pressure on the end surface of the rotating air-guiding piece positioning slider 33 on the rotating air-guiding piece 3 The inclined sliding surface 34 exerts pressure, and the pressure is perpendicular to the pressure-bearing inclined sliding surface 34, but when the rotating air guide 3 is not separated from the first positioning chute 11 on the inner wall of the chute shell 1, Both the pressing sliding member 2 and the rotating air guiding member 3 can only move axially in the chute shell member 1 (the spring 5 is gradually compressed during this process), and the The air guide holes 31 of the rotating air guide member 3 and the air guide holes 41 of the fixed air guide member 4 are not in the opposite state, and the air flow channel is not connected, that is, the air flow channel is closed; When the pressure-applying slanting surface 23 of the pressure-applying sliding member 2 continues to press on the pressure-receiving slanting surface 34 until the rotating air guide 3 is separated from the inner wall of the chute shell 1 in the axial direction After the first positioning chute 11, the positioning slider 33 of the rotary air guide is no longer restricted by the first positioning chute 11, and the pressure-applying inclined sliding surface 23 continues to slide axially. Apply pressure to the pressure-bearing inclined sliding surface 34, the pressure is perpendicular to the pressure-bearing inclined sliding surface 34, and the rotating air guide 3 is axially supported by the fixed air guide 4 and cannot continue Axial movement, so under the above pressure, the rotating air guide 3 rotates in the circumferential direction, that is, the pressure-bearing inclined sliding surface 34 rotates circumferentially along the first inclined sliding surface 14 until it rotates to the the higher side 151 of the second inclined sliding surface 15 (because the axial depth of the second positioning chute 12 is deeper than that of the first positioning chute 11 in the axial direction The depth should be small, so when the pressure-bearing inclined sliding surface 34 rotates in the circumferential direction to the higher side 151 of the second inclined sliding surface, it is stuck, and the higher side 151 of the second inclined sliding surface acts as a limit function), so as to realize that the pressure-bearing inclined sliding surface 34 of the rotating air guiding member 3 is in contact with the inclined sliding surface 14 on the inner wall of the chute shell 1 and slides along the inclined sliding surface 14 in place (this process relies on the elastic force of the spring 5 to restore the original shape, and the pressure-bearing inclined sliding surface 34 of the rotating air guide 3 slides along the inclined sliding surface 14 on the inner wall of the chute shell 1 Among them, the movement state of the rotating air guide 3 is axial movement and circumferential movement compound movement of rotation), after the rotating air guiding member 3 rotates at a certain angle (for example, 45 degrees), the air guiding hole 31 of the rotating air guiding member on the rotating air guiding member 3 and the fixed air guiding The air guide hole 41 of the fixed air guide member on the member 4 is in an opposite state, and the air flow passage is connected.

When the device is in the working state, that is, the cigarette filter is in the cigarette filter accommodating chamber 18 of the chute shell 1, and the airflow channel of the device is in an open state, at this time the rotating air guide 3 of the The pressure-bearing inclined sliding surface 34 is located on the inclined sliding surface 14 on the inner wall of the chute shell 1, when the cigarette filter is pushed axially inward in the cigarette filter receiving chamber 18 , the push force is transmitted to the pressure-applying slide 2 through the cigarette filter, and the pressure-applying inclined sliding surface 23 of the press-applying slide 2 is opposite to the rotating air-guiding piece on the rotating air-guiding piece 3 The pressure-bearing inclined sliding surface 34 on one end surface of the positioning slider 33 exerts pressure, and the pressure-bearing inclined sliding surface 34 moves axially along the higher side 151 of the second inclined sliding surface. Before the second inclined sliding surface 15 on the inner wall of the chute shell 1 contacts, both the pressing slide 2 and the rotating air guide 3 move axially in the chute shell 1, and During the process, the air guide holes 31 of the rotating air guide member 3 and the air guide holes 41 of the fixed air guide member 4 are in the opposite state, and the airflow channel is in the communicating state. When the pressure-applying inclined-sliding surface 23 continues to apply pressure to the pressure-bearing inclined-sliding surface 34, the higher side 341 of the pressure-bearing inclined-sliding surface 34 and the inner wall of the chute shell 1 In the process just before the higher side 151 of the second inclined sliding surface 15 on the second inclined sliding surface contacts, the rotating air guiding part 3 and the pressing sliding part 2 are both in the chute shell part 1 to do axial sliding. Afterwards, when the pressure-applying slide 2 continues to slide axially through the pressure-applying slanting surface 23 to apply pressure to the pressure-receiving slanting surface 34 , since the rotating air guide 3 is in the axial direction as a whole, It is also supported by the fixed air guide 4 and cannot continue to move axially. Therefore, under the pressure exerted by the above-mentioned pressure-applying inclined sliding surface 23 on the pressure-bearing inclined sliding surface 34, the rotating air guiding member 3 again undergoes circumferential movement. Rotate, so that the pressure-bearing inclined sliding surface 34 of the rotating air guide 3 is in contact with the inclined sliding surface 15 on the inner wall of the chute shell 1 and moves along the first sliding surface under the spring restoring force. The two inclined sliding surfaces 15 rotate and slide until the positioning slide block 33 of the rotating air guide 3 on the rotating air guide 3 slides back to the first positioning chute 11 on the inner wall of the chute shell 1 (this process relies on the elastic force of the spring 5 to restore the original shape, the pressure-bearing inclined sliding surface 34 of the rotating air guide 3 slides along the inclined sliding surface 15 on the inner wall of the chute shell 1 Among them, the motion state of the rotary air guide 3 is a compound motion of axial movement and circumferential rotation), and the positioning slider 33 of the rotary air guide 3 on the rotary air guide 3 slides down into the chute The first positioning chute 11 on the inner wall of the shell 1 is restricted and can only move axially. Sliding surface 23 matches. In the above process, due to the rotation of the rotating air guiding element 3 again at a certain angle (for example, 45 degrees), the air guiding hole 31 of the rotating air guiding element 3 on the rotating air guiding element 3 is connected to the fixed air guiding element 4. The air guide hole 41 of the fixed air guide is in a non-opposite state, the air flow channel is not connected, and the device returns to a natural state, that is, the air flow channel of the device is in a closed state.
