The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.
[0022] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.
[0023] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0024] like Figure 1-4 As shown, a high-capacity suction resistance tester includes a base 1, on which a product clamp 2, a suction resistance test device, a suction device, and a smoke exhaust device are fixedly mounted. The product clamp 2 is used to mount the product to be tested.
[0025] The suction device includes a large-capacity glass cover 3 and a piston 4. The large-capacity glass cover 3 is connected to the product clamp 2 via a suction hose. A smoke extraction device is connected to the large-capacity glass cover 3 via a smoke extraction hose and is used to extract smoke from inside the large-capacity glass cover 3. The piston 4 extends into the large-capacity glass cover 3 and slides within it. A drive device 5 is provided on the base 1. The output end of the drive device 5 is connected to the end of the piston 4 that extends out of the large-capacity glass cover 3. The drive device 5 is used to drive the piston 4 to slide within the large-capacity glass cover 3. During suction, the electronic cigarette is mounted on the product clamp 2. The operation of the drive device 5 drives the piston 4 to rise within the large-capacity glass cover 3, thereby generating a negative pressure suction force within the large-capacity glass cover 3 and the suction hose. This causes the electronic cigarette on the product clamp 2 to start working, and the smoke flows into the large-capacity glass cover 3 through the suction hose, completing the suction process. After the test is completed, the smoke is drawn out of the large-capacity glass cover 3 by the smoke exhaust component, and at the same time the drive device 5 drives the piston 4 to descend to the initial position inside the large-capacity glass cover 3.
[0026] The suction resistance testing device includes a pressure transmitter 6 and a detection sensor 7. The detection sensor 7 is connected to a large-capacity glass cover 3 and is used to detect whether there is smoke inside the large-capacity glass cover 3. A first mounting base 8 is provided on the base 1, and the pressure transmitter 6 is fixedly connected to the first mounting base 8. The pressure transmitter 6 is connected to the product clamp 2 through a pipeline. The pressure transmitter 6 is externally connected to a controller for detecting the suction pressure value of the suction hose. During the test, when the drive device 5 drives the piston 4 to rise inside the large-capacity glass cover 3, the electronic cigarette is activated, and smoke flows from the suction hose into the large-capacity glass cover 3. At this time, the detection sensor 7 can detect the smoke inside the large-capacity glass cover 3, and then controls the pressure transmitter 6 to work. The pressure transmitter 6 detects the suction pressure inside the suction hose and feeds the suction pressure data back to the controller. The controller has a preset control program, which converts the suction pressure data provided by the pressure transmitter 6 into suction resistance data for the user to view, thereby realizing the function of testing the suction resistance of the electronic cigarette. Using a large-capacity glass cover can reduce the number of cycles required for a single product test, greatly improving testing efficiency and reducing labor costs.
[0027] like Figure 2 As shown, the drive device 5 includes a drive motor 51, which is connected to a base 1. A rotatable lifting screw 52 is mounted on the base 1. The output end of the drive motor 51 is connected to the lifting screw 52. A lifting slider 53 slides on the lifting screw 52 and is connected to a piston 4. During operation, the drive motor 51 drives the lifting screw 52 to rotate, thereby causing the lifting slider 53 to slide on the lifting screw 52, achieving the purpose of driving the piston 4 to move up and down within the large-capacity glass cover 3. In other embodiments, the drive device 5 can also use a cylinder structure or other devices or structures capable of linear drive.
[0028] In order to limit and guide the movement direction of the lifting slider 53, a guide rail 54 is fixedly installed on the base 1, and the lifting slider 53 is slidably engaged with the guide rail 54. When the drive motor 51 is working, the lifting screw 52 will drive the lifting slider 53 to slide on the guide rail 54, thereby limiting and guiding the movement direction of the lifting slider 53, so that the piston 4 can move stably up and down in the large-capacity glass cover 3, and improving the stability of the transmission.
[0029] In this embodiment, a drive wheel 55 is provided on the output end of the drive motor 51, and a driven wheel 56 is provided on one end of the lifting screw 52. A transmission belt 57 is sleeved on the drive wheel 55 and the driven wheel 56. During operation, the drive motor 51 drives the drive wheel 55 to rotate, which in turn drives the transmission belt 57 to move. The transmission belt 57 pulls the driven wheel 56 to rotate, thereby driving the lifting screw 52 to rotate. The lifting screw 52 drives the lifting slider 53 to slide up and down on the guide rail 54.
[0030] like Figure 1 , Figure 3 As shown, a second mounting base 9 is fixedly installed on the base 1. Two finger cylinders 10 are fixedly installed on the second mounting base 9. One finger cylinder 10 is positioned at the corresponding position of the suction hose and can clamp the suction hose to control the opening or closing of the suction hose. The other finger cylinder 10 is positioned at the corresponding position of the exhaust hose and can clamp the exhaust hose to control the opening or closing of the exhaust hose. In specific operation, during suction, the finger cylinder 10 on the exhaust hose side is activated, clamping the exhaust hose and closing it; the finger cylinder 10 on the suction hose side is deactivated, allowing the suction hose to open and the smoke to flow into the large-capacity glass cover 3 through the suction hose. During the smoke extraction process after testing, the two finger cylinders 10 interchange their functions. The finger cylinder 10 corresponding to the suction hose clamps the suction hose, closing it; the finger cylinder 10 corresponding to the smoke extraction hose is inactive, allowing the smoke extraction hose to remain open. This ensures that when the smoke extraction device is operating, the smoke inside the large-capacity glass cover 3 can flow into the device through the smoke extraction hose. Replacing the existing clamp valve with finger cylinders 10 improves stability and prevents control failure due to overheating during prolonged operation.
[0031] In this embodiment, the detection sensor 7 is a photoelectric switch that is fixedly installed on both sides of the lower end of the large-capacity glass cover 3; in other embodiments, other sensors capable of detecting smoke may also be used.
[0032] The large-capacity glass cover 3 has a scale 31 on its side wall. By setting the scale 31, the suction capacity of the suction device can be adjusted so that it can be used to meet the testing needs of different types of products, thereby improving the versatility of the large-capacity suction resistance tester.
[0033] The smoke extraction device includes a vacuum pump 11, which is fixedly mounted on the base 1. The input end of the vacuum pump 11 is connected to the large-capacity glass cover 3 via a smoke extraction hose. During the smoke extraction process, the vacuum pump 11 operates to extract the smoke from inside the large-capacity glass cover 3 through the smoke extraction hose and discharge it into the outside air, thereby achieving the purpose of smoke extraction from the large-capacity glass cover 3.
[0034] like Figure 4 As shown, the product fixture 2 includes a third mounting base 21, which is fixedly mounted on the base 1. Four suction nozzles 22 and four air pipe connectors 23 are evenly distributed on the third mounting base 21. Each suction nozzle 22 corresponds to one air pipe connector 23, which is used to connect an air pipe to the suction hose and the pressure transmitter 6. By providing four suction nozzles 22, this high-capacity suction resistance testing machine can simultaneously perform suction resistance tests on four electronic cigarettes, further improving testing efficiency. In other embodiments, the number of suction nozzles 22 can also be any other arbitrary number.
[0035] The above-described specific embodiments are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
