Technical Field
[0001] This utility model belongs to the field of smoking machine technology, specifically relating to a smoking machine interface suitable for various diameters. Background Technology
[0002] Electronic cigarettes are a type of new tobacco product. Since their introduction in 2003, the market has expanded rapidly. However, the safety risks they pose have become increasingly clear, and corresponding testing methods are constantly being improved. In order to analyze the components of electronic cigarette smoke, it is necessary to capture the smoke. The usual practice is to collect the smoke components through a smoking device.
[0003] Currently, when collecting and analyzing the chemical composition of emissions from regular cigarette smoke, multi-channel smoking machines (such as 20-channel linear smoking machines) are generally used. These machines utilize cigarette holders to hold the test cigarette samples and collect particulate matter from the smoke, thus enabling smoke composition analysis. However, unlike regular cigarettes, most e-cigarettes lack standardized cylindrical filters. Furthermore, the wide variety of e-cigarettes and their diverse shapes and mouthpieces on the market mean that traditional cigarette holders cannot achieve proper gripping and sealing during inhalation, hindering the collection of e-cigarette aerosols. For e-cigarettes with irregularly shaped mouthpieces, special smoking machine interfaces need to be designed to ensure proper gripping and airtightness. However, redesigning the smoking machine interface based on the e-cigarette mouthpiece presents challenges such as high production costs and incompatibility with e-cigarettes of different mouthpiece sizes, resulting in poor versatility. Utility Model Content
[0004] In view of the problems existing in the prior art, this utility model provides a smoking machine interface that is suitable for various diameters, so that the smoking machine interface can be adapted to electronic cigarettes of different diameters, thereby improving the applicability of the smoking machine.
[0005] The solution adopted by this utility model to solve its technical problem is as follows: an interface for smoking machines suitable for various diameters, including a smoking machine, a bracket, and an electronic cigarette. The electronic cigarette consists of a cigarette body and a mouthpiece, and also includes an interface assembly, a pushing unit, and a pneumatic clamping unit. The bracket has a U-shaped structure and a supporting slide is provided on the bracket. The interface assembly is supported on the front side of the smoking machine by the bracket, and the electronic cigarette is supported by the supporting slide and faces the interface assembly. The interface assembly consists of a detachable interface and a fixed interface. The fixed interface is fixed on the smoking machine, and the detachable interface is installed on the front side of the fixed interface. A clamping airbag is arranged around the inner wall of the detachable interface. The pneumatic clamping unit includes a main airbag, which is located behind the cigarette body of the electronic cigarette. An elastic telescopic reset member is horizontally arranged inside the main airbag, and the main airbag and the clamping airbag are connected by an air guide tube. A pushing mechanism is provided on the bracket behind the cigarette body of the electronic cigarette for pushing the mouthpiece into the interface assembly and pushing the main airbag to compress.
[0006] Furthermore, the support slide includes a placement seat disposed within the bracket, and multiple guide rollers are rotatably arranged within the placement seat along the seat body direction. The surfaces of the guide rollers have an arc-shaped structure and match the shape of the electronic cigarette body.
[0007] Furthermore, the elastic telescopic reset component consists of a telescopic rod and a spring. The telescopic rod is horizontally fixed inside the main airbag, and the spring is fitted onto the telescopic rod, with both ends of the spring connected to both sides of the main airbag.
[0008] Furthermore, the pushing mechanism includes a screw that is horizontally rotated and fitted inside the bracket. A handle is fixed to the outer end of the screw. A nut is threaded onto the screw, and an inverted L-shaped push rod is vertically fixed to the side of the nut. The front end of the push rod is fixed to the rear of the main airbag.
[0009] Furthermore, a baffle is provided on the front side of the detachable interface.
[0010] Furthermore, the bottom surface of the bracket is provided with a guide groove along the screw direction, and a guide block is fixed on the nut. The nut is slidably fitted into the guide groove through the guide block.
[0011] Furthermore, the detachable interface has an internal thread on the inner wall of the side away from the clamping airbag, and the fixed interface has an external thread on the outer wall. The detachable structure is installed on the fixed structure through threaded engagement, and a sealing gasket is provided on the side wall of the fixed interface on the bracket.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This invention, through the threaded engagement of a detachable interface and a fixed interface, as well as the pneumatic clamping design of the clamping airbag and main airbag, can adapt to e-cigarette mouthpieces of different diameters and shapes, expanding the applicability of the smoking machine. The pneumatic clamping design of the clamping airbag and main airbag ensures the sealing between the e-cigarette mouthpiece and the interface assembly, effectively preventing smoke leakage and improving the collection efficiency of the smoking machine. Furthermore, the linkage design of the drive mechanism and the pneumatic clamping unit allows the insertion and sealing clamping of the e-cigarette to be completed in one operation, simplifying the operation process and improving work efficiency. The guide roller design supporting the slide reduces the friction of the e-cigarette during movement, ensuring stable movement and accurate docking. The detachable interface design facilitates the disassembly and maintenance of the interface assembly, reducing cleaning and replacement costs. By adapting to multiple e-cigarettes with a single interface assembly, the additional interface costs required for different specifications of e-cigarettes are reduced, thus lowering production costs.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0020] Please see Figure 1-4 This utility model provides a technical solution applicable to various smoking machine interfaces of different diameters: Example
[0021] according to Figure 1 and Figure 2As shown, a smoking machine interface suitable for various diameters mainly includes a smoking machine 1, a bracket 2, an interface assembly 5, a pushing mechanism 6, an electronic cigarette 4, and a pneumatic clamping unit 7. The bracket 2 is located in front of the smoking machine's inlet, and the interface assembly 5 is located at the smoking machine's inlet and is supported and fixed by the bracket 2. The bracket 2 supports the electronic cigarette 4, placing the electronic cigarette 4 in front of the interface assembly 5, with the mouthpiece 42 of the electronic cigarette 4 facing the interface assembly 5. The mouthpiece 42 of the electronic cigarette 4 is sealed and connected to the smoking machine 1 through the interface assembly 5. A pushing mechanism 6 is located on the bracket 2 behind the body 41 of the electronic cigarette, used to push the mouthpiece 42 of the electronic cigarette into the interface assembly 5. The pneumatic clamping unit 7 is located at both ends of the electronic cigarette 4, used to seal and fix the mouthpiece 42 of the electronic cigarette within the interface assembly 5.
[0022] The bracket 2 has a U-shaped structure. A support slide 3 is provided in the middle of the bracket 2. The support slide 3 includes a base 31 welded and fixed to the bottom surface of the bracket 2. A U-shaped placement seat 32 is fixedly provided above the base 31. Multiple guide rollers 33 are arranged rotatably in the placement seat 32 along the seat body direction. The surface of the guide rollers 33 is arc-shaped and matches the shape of the cigarette body 41 of the electronic cigarette 4. The electronic cigarette 4 is placed in the support slide 3 and is on the same axis as the interface component 5. When the pushing mechanism 6 pushes the electronic cigarette 4 forward to dock with the interface component 5, the guide rollers 33 play a role in sliding and guiding the electronic cigarette and limiting its movement, so that the electronic cigarette is guided to the interface component 5 in a directional manner and the friction of the electronic cigarette body 41 when it moves forward is reduced.
[0023] The interface assembly 5 consists of a detachable interface 52 and a fixed interface 51. The fixed interface 51 is directly fixed to the inlet of the smoking machine 1 and extends through one side of the bracket 2, supported by the bracket 2. The detachable interface 52 is installed in front of the fixed interface 51. A clamping airbag 53 is arranged around the inner wall of the detachable interface 52. The clamping airbag 53 is used to seal and clamp the mouthpiece 42. Taking a cylindrical mouthpiece 42 as an example, the clamping airbag 53 is an annular airbag with a channel in the middle for the mouthpiece 42 to be inserted and communicate with the smoking machine 1. The clamping airbag 53 is controlled to expand and contract by the air pressure clamping unit 7. When the mouthpiece 42 is inserted into the detachable interface 52, the clamping airbag 53 expands and presses against the mouthpiece 42, thus clamping and sealing the mouthpiece 42. A baffle 54 is provided in front of the detachable interface 52 to prevent the body 41 of the electronic cigarette 4 from entering the interface.
[0024] An air pressure clamping unit 7 is provided on the rear side of the electronic cigarette 4, such as... Figure 3As shown, the pneumatic clamping unit 7 includes a main airbag 71. Rigid plates are provided on both sides of the main airbag 71 to support and stabilize the shape of the main airbag 71. A telescopic rod 72 is horizontally fixed inside the main airbag 71. A spring 73 is fitted on the telescopic rod 72. The two ends of the spring 73 are respectively connected to the two sides of the main airbag 71. The main airbag 71 and the clamping airbag 53 in the detachable interface 52 are connected by an air guide tube 74. In order to accommodate the change in the moving distance between the main airbag and the clamping airbag, the air guide tube is designed as a pipe structure with telescopic function. When the main airbag 71 is compressed against the elastic force of the spring 73, the gas in the main airbag 71 will enter the clamping airbag 53 along the air guide tube 74, causing the clamping airbag 53 to inflate and seal the mouthpiece 42.
[0025] The main airbag 71 is located at the rear of the electronic cigarette 4, and the pushing mechanism 6 is located at the rear of the electronic cigarette 4 and the main airbag 71. The main airbag 71 is moved forward by the pushing mechanism 6. During the forward movement, the main airbag 71 first contacts the rear end of the cigarette body 41. As the main airbag 71 moves forward, it will push the electronic cigarette 4 forward. When the mouthpiece 42 of the electronic cigarette is inserted into the detachable interface 52 and the front end of the cigarette body 41 is blocked by the baffle 54, the electronic cigarette can no longer be pushed forward. At this time, the pushing mechanism 6 continues to control the main airbag 71 to move forward, which will overcome the elastic force of the spring 73 and compress the main airbag 71, so that the gas in the main airbag 71 is forced into the clamping airbag 53, thereby achieving the clamping and sealing of the mouthpiece 42. The mouthpiece 42 of the electronic cigarette is fixed, and the rear end of the cigarette body 41 is pushed by the main airbag 71, thereby limiting and clamping the electronic cigarette 4 to the front side of the smoking machine 1, so that the electronic cigarette can be stably positioned at the front side of the smoking machine 1 for smoke absorption. This method can link the pushing and inserting of the electronic cigarette with the sealing clamping of the mouthpiece 42, so that the insertion and sealing of the electronic cigarette on the smoking machine can be achieved with a single operation, which is simple and convenient.
[0026] The pushing mechanism 6 includes a screw 61 horizontally rotated and fitted inside the bracket 2. The two ends of the screw 61 are respectively fitted onto the base 31 and the other side of the bracket 2 via a rotating shaft and a bearing seat. A rotating handle 63 is fixed to the outer end of the screw 61. A nut 62 is threaded onto the screw 61, and an inverted L-shaped push rod 65 is vertically fixed to the side of the nut 62. The front end of the push rod 65 is fixed to a rigid plate behind the main airbag 71. The screw 61 is rotated by rotating the rotating handle 63. With the cooperation of the screw 61 and the nut 62, the push rod 65 can push the main airbag 71 forward, so that the main airbag 71 contacts the rear end of the smoke body 41 and pushes it forward. A guide groove is opened on the bottom surface of the bracket 2 along the direction of the screw 61. A guide block 64 is fixed on the nut 62. The nut 62 is slidably fitted into the guide groove through the guide block 64. The guide groove and the guide block 64 guide the movement of the nut 62 and the main airbag 71.
[0027] In practical use, this utility model provides an interface for smoking machines with various diameters. First, the electronic cigarette 4 is placed on the guide roller 33 of the support slide 3. Then, the handle 63 is rotated to control the screw 61 to rotate. With the cooperation of the screw 61 and the nut 62, the push rod 65 pushes the main airbag 71 forward, so that the main airbag 71 contacts the rear end of the cigarette body 41 and pushes it forward. When the mouthpiece 42 of the electronic cigarette 4 is inserted into the detachable interface 52 and the front end of the cigarette body 41 is blocked by the baffle 54, the electronic cigarette 4 can no longer be pushed forward. At this time, the main airbag 71 is controlled to overcome the elasticity of the spring 73 and compress it. The gas in the main airbag 71 is forced into the clamping airbag 53, causing the clamping airbag 53 to expand and bulge, sealing and clamping the mouthpiece 42 around it, thus achieving the clamping and sealing of the mouthpiece 42. Then, the smoke from the electronic cigarette 4 is drawn in by the smoking machine 1.
[0028] After the smoking machine 1 is finished operating, the control screw 61 reverses. At this time, the main airbag 71 expands and reshapes under the rebound force of the spring 73. The gas in the clamping airbag 53 returns to the main airbag 71 through the air guide tube 74. The sealing clamping effect of the clamping airbag 53 on the mouthpiece 42 disappears. Finally, the electronic cigarette 4 can be removed from the support slide 3. Example
[0029] Based on Example 1, such as Figure 4 As shown, the detachable interface 52 and the fixed interface 51 can be disassembled and assembled with each other. The inner wall of the detachable interface 52 away from the clamping airbag 53 is provided with an internal thread, and the outer wall of the fixed interface 51 near the detachable interface 52 is provided with an external thread. The detachable interface 52 can be threadedly installed on the fixed structure. A sealing gasket 8 is provided on the inner wall of the bracket 2 located on the side of the fixed interface 51 and fitted onto the fixed structure to improve the sealing performance at the connection between the detachable interface 52 and the fixed interface 51.
[0030] The detachable interface 52 is equipped with a sealing connector that connects to the clamping airbag 53. The end of the air duct 74 is detachably connected to the detachable interface 52 through the sealing connector. The clamping airbag 53 inside the detachable interface 52 is not limited to annular airbags. The shape of the airbag that can be used here matches the shape of the mouthpiece 42 of commercially available electronic cigarettes 4, such as annular or flat mouth. When it is necessary to seal and clamp electronic cigarettes 4 with different shapes of mouthpiece 42, it is only necessary to replace the detachable interface 52 to match the shape of the detachable interface 52 with the mouthpiece 42. This structure can then be applied to electronic cigarettes 4 with different shapes and sizes, further improving the applicability of this structure.
[0031] The above description is only a preferred embodiment of the present utility model and does not limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
