And, a start button 220 is provided on the lower housing 130

During detection, the main working principle of the air tightness detection device 10 applied to the electronic cigarette of the invention is as follows:

when the electronic cigarette positioning device is used, a worker places the electronic cigarette 20 to be tested into the positioning jig 300 (as shown in fig. 6), and then sets required values, such as pressure, negative pressure and the like, through the man-machine interaction console 211, and then presses the start button 220, so that the air cylinder 400 starts to operate. The telescopic rod 410 of the air cylinder 400 drives the lifting platform 420 to descend, and the vacuum pumping part 500 gradually approaches the electronic cigarette 20. In the process, the negative pressure suction nozzle 510 preferentially contacts the power connection port 21 of the electronic cigarette 20, and under the pressure of the cylinder 400, the negative pressure suction nozzle 510 is tightly attached to the edge of the power connection port 21, so that the negative pressure suction nozzle 510 covers the power connection port 21, and a small closed space is formed at the power connection port 21. Then, the vacuum machine starts to work, the air in the closed space is pumped out through the air suction through hole 511 and the negative pressure channel 521, negative pressure is formed in the closed space, the closed space is kept for a certain time in the negative pressure state, if the pressure in the closed space can be kept constant, the air tightness of the power connection port 21 of the electronic cigarette 20 is good, and at this time, the indicator lamp 212 displays that the electronic cigarette 20 is qualified for detection. Then, the air cylinder 400 drives the vacuum part 500 to ascend, the negative pressure suction nozzle 510 no longer presses the electronic cigarette 20, the worker takes the electronic cigarette away and replaces the electronic cigarette 20 with a new electronic cigarette 20, and the operation is repeated to perform a new round of test.

Moreover, for the air tightness detecting device 10 applied to the electronic cigarette of the present invention, a worker may use one of the stations alone for detection, or may use two stations at the same time. Even, the staff can set different values for each station through the human-computer interaction console 211, and the electronic cigarettes 20 of two different models can be detected simultaneously. Such a design is advantageous for improving the detection efficiency of the air-tightness detection device 10.

Further, in the present embodiment, as shown in fig. 7, the negative pressure suction nozzle 510 is provided with: the limiting block 512, the guiding inclined plane 513 and the extending blocking piece 514, the limiting through hole 531 of the buffer plate 530 is provided with a stepped groove 532 (as shown in fig. 4) matched with the limiting block 512, and the limiting block 512 and the stepped groove 532 are matched to realize that the negative pressure suction nozzle 510 is quickly clamped on the buffer plate 530. The guiding inclined surface 513 is engaged with the power connection port 21 of the electronic cigarette 20, and the extending stop piece 514 is used for abutting against the edge of the power connection port 21.

During detection, when the negative pressure suction nozzle 510 gradually contacts the power connection port 21, the guiding inclined plane 513 can provide a guiding function for the negative pressure suction nozzle 510, that is, when the negative pressure suction nozzle 510 deviates from the power connection port 21, the guiding inclined plane 513 abuts against the edge of the power connection port 21, so as to generate a pushing force, and the negative pressure suction nozzle 510 is turned back to be aligned with the power connection port 21. When the negative pressure suction nozzle 510 presses and holds the power connection port 11, the extension flap 514 also presses and holds the edge of the power connection port 21, so that the extension flap 514 seals and blocks the gap between the negative pressure suction nozzle 510 and the power connection port 21, thereby improving the sealing degree. Therefore, the negative pressure suction nozzle 510 and the power connection port 21 can be aligned stably during detection, and under the action of the extension baffle 514, the edges of the negative pressure suction nozzle 510 and the power connection port 11 are tight, so that external air cannot enter a closed space at the power connection port 21, and the detection accuracy is ensured.

In this embodiment, it is preferable that the negative pressure suction nozzle 510 is of a super rubber structure and the buffer plate 530 is of a rubber structure. The negative pressure suction nozzle 510 with the acrylic adhesive structure can have elasticity and rigidity, so that the negative pressure suction nozzle 510 can be tightly attached to the power connection port 21, and can transmit corresponding pressure. When the negative pressure suction nozzle 510 presses and holds the electrical port 21, other positions of the electronic cigarette 20 are pressed and held with the buffer plate 530, and the buffer plate 530 with a rubber structure has the function of reducing the impact force, so that the electronic cigarette 20 can be prevented from being damaged.

Furthermore, during the detection, the structural size of the electronic cigarette 20 may be changed a little due to the different models of the electronic cigarette 20, and conventionally, the fixture matched with the detected electronic cigarette 20 is replaced, which is time-consuming and labor-consuming. In order to make the positioning jig 300 better match with various electronic cigarettes 20 of different models, thereby eliminating the step of replacing the jig, the present invention makes a special design for the structure of the positioning jig 300.

Specifically, as shown in fig. 8 and 9, the positioning fixture 300 includes a base 310 and a clamping assembly 320, the base 310 is mounted on the placing platform 110, a positioning groove 311 is formed on the base 310, and the clamping assembly 320 is movably disposed on a groove wall of the positioning groove 311. Moreover, the number of the clamping assemblies 320 is two, the two groups of clamping assemblies 320 are symmetrically distributed in the positioning slot 311, and the two groups of clamping assemblies 320 are used for clamping the outer wall of the electronic cigarette 20.

In the present embodiment, as shown in fig. 9 and 10, each group of clamping assemblies 320 includes: the first clamping arm 321 is movably hinged to the second clamping arm 322, the first elastic element 323 connects the base 310 and the first clamping arm 321, and the first elastic element 323 provides the first clamping arm 321 with an elastic force toward the center of the positioning slot 311; the second elastic member 324 connects the base 310 and the second clipping arm 322, and the second elastic member 324 provides an elastic force to the second clipping arm 322, and the direction of the elastic force is also toward the center of the positioning slot 311.

in an initial state, that is, when the electronic cigarette 20 is not placed in the positioning slot 311, the state of the clamping assembly 320 is as shown in fig. 12, at this time, the first elastic member 323 and the second elastic member 324 are in a free state, and the first clamping arm 321 and the second clamping arm 322 are close to the center of the positioning slot 311; an included angle is formed between the first clamping arm 321 and the second clamping arm 322, and the included angle is greater than 90 degrees and smaller than 180 degrees (obtuse angle);

when the worker inserts the electronic cigarette 20 into the positioning slot 311, the electronic cigarette 20 props up the two sets of clamping components 320, the first elastic member 323 and the second elastic member 324 are compressed, and the size of the included angle between the first clamping arm 321 and the second clamping arm 322 changes along with the radian of the outer wall of the electronic cigarette 20. At this time, the elastic force provided by the first elastic member 323 and the second elastic member 324 enables the first clamping arm 321 and the second clamping arm 322 to abut against the electronic cigarette 20, and the two sets of clamping assemblies 320 cooperate to clamp and fix the electronic cigarette 20; meanwhile, the first clamping arm 321 and the second clamping arm 322 can deflect around the rotating shaft 325 as a center, and an included angle between the first clamping arm 321 and the second clamping arm is changed to be more attached to the outer wall of the electronic cigarette 20, so that the electronic cigarette 20 is clamped more stably. So, the electronic cigarette 20 of multiple different models can be compromise to positioning jig 300 after the improvement for need not change the tool when detecting different model electronic cigarettes 20, thereby made things convenient for staff's operation, improved work efficiency.
