Description

[0002] During the production process of e-cigarette oil, the quality of the oil needs to be inspected according to the standards of the regulatory agency. Usually the key test parameters of the oil include nicotine content, propylene glycol / vegetable glycerin ratio (PG / VG), water content, boiling point, refractive index, density, specific gravity and pH value.

[0003] In the prior art, the component detection of e-liquid usually relies on manual or automatic pipetting to extract a portion of the e-liquid product and inject it into an instrument corresponding to different test parameters, and then operate the instrument to perform component detection.

[0004] In a production line of e-liquid or a batch of e-liquid products, there are many samples to be tested, so manual pipetting is inefficient. When mechanical automatic pipetting is used, one pipette usually only extracts e-liquid from one container.

[0019] 2. The electronic cigarette oil component detector does not test the four sample containers separately during the testing process. Instead, it is divided into three testing steps. First, the liquid circuit is controlled to mix the oils in the four sample containers into one portion for testing. Considering that the product qualification rate is usually high, the mixed sample is likely to have qualified ingredients, so most testing processes only require the first step. If the product ingredients are detected to be unqualified, the second step of testing is carried out, and then the product is divided into two portions and mixed separately for synchronous testing to determine which portion contains unqualified products. Then the third step is carried out to separately test the portion detected to be unqualified in the second step. This makes the testing process faster and reduces the number of component detectors required to be set up.

[0020] 3. The electronic cigarette oil component detector can automatically shake the sample container through the swing component during the transportation process of the sample container, so as to mix it evenly and improve the detection accuracy. The swing process can be automatically generated during the transportation process by using the guide groove, which also saves time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] For example, see Figure 1-Figure 6 , an electronic cigarette oil component detector, comprising a workbench 100, on which two component detectors 200 are arranged, characterized in that: a conveying mechanism 400 and a liquid suction mechanism 500 are also arranged on the workbench 100, and the conveying mechanism 400 is used to convey a sample container 300; The liquid suction mechanism 500 includes a first screw conveying assembly 510 disposed on the workbench 100, a first mounting seat 520 is disposed on the first screw conveying assembly 510, a liquid suction pipe assembly 530 is disposed on the first mounting seat 520, and the liquid suction pipe assembly 530 includes a first liquid suction pipe 531, a second liquid suction pipe 532, a third liquid suction pipe 533 and a fourth liquid suction pipe 534 arranged in sequence from left to right; The liquid aspiration mechanism 500 further includes a liquid path control component 540. After the first liquid aspiration tube 531, the second liquid aspiration tube 532, the third liquid aspiration tube 533 and the fourth liquid aspiration tube 534 respectively aspirate the e-liquid in the four sample containers 300, the liquid path control component 540 controls the flow direction of the four e-liquids, thereby controlling the four e-liquids to be mixed into one part, mixed into two parts or not mixed for component detection; The workbench 100 is also provided with a pipetting mechanism 600, which includes a second screw conveying assembly 610 provided on the workbench 100, a second mounting seat 620 provided on the second screw conveying assembly 610, a pipette assembly 630 provided on the second mounting seat 620, and the pipette assembly 630 includes a first electric pipette 631, a second electric pipette 632, a third electric pipette 633 and a fourth electric pipette 634 arranged in sequence from left to right; The first electric pipette 631 , the second electric pipette 632 , the third electric pipette 633 and the fourth electric pipette 634 are all provided with a pipette nozzle 635 , and the four pipette nozzles 635 are respectively connected to the upper ports of the first pipette tube 531 , the second pipette tube 532 , the third pipette tube 533 and the fourth pipette tube 534 .

[0037] In this embodiment: First, in order to realize automatic component detection of the e-liquid placed in a large number of sample containers 300, a conveying mechanism 400 is installed on the workbench 100 along the left and right directions, and four sample containers 300 are conveyed to the four detection stations on the right at one time through the conveying mechanism 400.

[0038] At this time, the first screw conveying assembly 510 that moves up and down and front and back biaxially drives the first mounting seat 520 to descend, so that the first pipette 531, the second pipette 532, the third pipette 533 and the fourth pipette 534 are respectively inserted into the four sample containers 300. Then, the first electric pipette 631, the second electric pipette 632, the third electric pipette 633 and the fourth electric pipette 634 are controlled to generate a negative pressure of a corresponding magnitude according to the set pipetting amount, and then the second screw conveying assembly 610 that moves back and forth, up and down, and left and right triaxially drives the second mounting seat 620 to descend, so that the four pipette nozzles 635 are respectively inserted into the first pipette 531, the second pipette 532, the third pipette 533 and the fourth pipette 534. At this time, the tobacco oil in the four sample containers 300 will be extracted into the pipette assembly 630 under the action of suction.

[0039] The second screw conveying assembly 610 then drives the second mounting seat 620 to move backward to the position of the component detector 200 to drip the smoke oil, and then controls the component detector 200 to analyze the smoke oil components.

[0040] Secondly, considering that the unqualified rate of regular e-liquid products is usually very low and unqualified products are rarely encountered, in order to improve the detection efficiency, the liquid path of the liquid pipette assembly 530 is controlled.

[0041] Specifically, the e-liquids in the four sample containers 300 are first mixed into one portion for testing. If the components detected by the component detector 200 are qualified, the four sample containers 300 can be further transported to the right through the transport mechanism 400.

[0042] If the test fails, the four sample containers 300 are further mixed into two parts, and after the two parts are mixed, they are respectively tested for components by two component detectors 200.

[0043] If one of them is qualified and the other is unqualified, the two sample containers 300 corresponding to the unqualified one are further extracted without mixing and tested separately using two component detectors 200. At this time, it can be clearly determined which sample container 300 has the unqualified e-liquid component.

[0044] If both samples are unqualified, the e-liquid in the four sample containers 300 are further extracted separately and tested in sequence without mixing.

[0045] It should be supplemented that the component detector 200 can be selected from different instruments according to the parameters to be tested, such as using a density meter to test the density of the e-liquid, using a refractometer to test the refractive index, and using a Brix meter to test the Brix content, etc. Usually, the instrument interface for detecting components can automatically detect the e-liquid by dropping it in. As a conventional technical means, the structure and working principle of the specific component detector 200 will not be described in detail.

[0046] The sample container 300 may be a smoke oil product produced on a production line, which is injected after extraction, or may be a smoke oil sample on a testing line.

[0047] The pipette assembly 630 can be automatically controlled according to the program to accurately absorb a set volume of e-liquid. As conventional technical means, the specific structure and working principle of the pipette assembly 630 are not described in detail.

[0048] When the pipette assembly 630 is working, the smoke oil only contacts the suction nozzle 635. Usually, if the suction nozzle 635 is a disposable product and needs to be replaced after use, an automatic replacement device can be set, or a reusable product can be selected. A cleaning tank 700 is installed on the workbench 100, and the pipette assembly 530 and the suction nozzle 635 can be cleaned in the cleaning tank 700.

[0049] Four sample containers 300 are selected to correspond to four pipette assemblies 530 and four pipette assemblies 630 , and the specific number is not limited and may also be six, eight, etc.

[0063] In this embodiment, when testing the composition of the e-liquid, the e-liquid in the sample container 300 is usually shaken before extraction to improve the accuracy of the e-liquid composition test result. Therefore, the step of shaking the e-liquid is also required to be automated.

[0064] When the stage 450 is in the first horizontal section 4741, the two guide rods 473 are parallel to each other, and the sample container 300 remains vertically upward without shaking. When the stage 450 moves to the wave section 4742, the front and rear guide rods 473 are driven by the two wave sections 4742. Since the crests and troughs of the two wave sections 4742 are staggered, when one guide rod 473 is at the lower side, the other guide rod 473 is at the upper side, and the two guide rods 473 are alternately moved up and down, so that the rotating seat 464 swings back and forth based on the X-axis in the arc groove 463. This drives the sample container 300 to swing back and forth to shake it evenly.
