Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarette oil detection and sampling, and in particular to a sampling device for detecting the content of components in a liquid cigarette cartridge which can prevent pollution. Background Art

[0002] At present, in order to strengthen market supervision, it is necessary to use e-liquid sampling devices to assist market regulators in extracting e-liquid on the market on site.

[0003] The Chinese patent with patent number CN213875124U discloses a pollution-proof sampling device for detecting the component content of liquid cigarette cartridges, including a sampling device body, a piston head, a liquid storage chamber and a cleaning ring. The upper side axis of the sampling device body is connected to a rotating rod, and a disc is installed in the middle of the rotating rod, and a cylinder is installed at the lower end of the disc. A groove is provided on the side of the rotating block, the piston head is located inside the liquid storage chamber, and a fixed block is installed at the lower end of the sampling device body. A first spring is installed between the sampling head and the fixed block, and a second spring is welded and fixed between the middle of the clamping block and the inside of the sampling device body.

[0004] The sampling device for detecting the content of components in liquid cigarette cartridges with anti-pollution described in the above-mentioned patent can extract the cigarette oil and clean the cigarette oil adhered to the sampling port of the device when in use. However, since the extraction head on the sampling device for detecting the content of components in liquid cigarette cartridges with anti-pollution structure is a hollow cylindrical shape inside, it is impossible to directly extract the cigarette oil in the sampled cigarette cartridge, which is very inconvenient for the market regulators on site. At the same time, since the cigarette oil on the market is too viscous and does not meet the detection standards of the detector, the cigarette oil extracted by the sampling device for detecting the content of components in liquid cigarette cartridges with anti-pollution structure needs to be diluted by the detector before the next step of detection can be carried out, which makes the subsequent detection of the cigarette oil more cumbersome. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a sampling device for detecting the content of liquid cigarette cartridge components, which is pollution-proof and can directly extract the cigarette oil from the sampled cigarette cartridges on the market, and can directly dilute the cigarette oil after extracting it, so as to facilitate subsequent detection.

[0007] (II) Technical solution

[0008] The utility model is achieved through the following technical scheme: the utility model proposes a sampling device for detecting the component content of liquid cigarette cartridges that can prevent pollution, including a negative pressure sampling tube, a sampling needle tube is installed in the middle of the bottom end of the negative pressure sampling tube, a fixed screw sleeve is installed outside the negative pressure sampling tube and located outside the sampling needle tube, two installation grooves are arranged on opposite sides of the fixed screw sleeve, a hook foot is installed in each of the installation grooves, a short shaft is fixed to the upper part of the two side walls of each hook foot, a torsion spring is installed on the outside of each short shaft, a clamping groove is arranged at the clamping end of the hook foot, a threaded portion is installed on the negative pressure sampling tube at the matching position with the fixed screw sleeve, a cross swivel is also installed in the middle of the outer side of the negative pressure sampling tube, and a diluent storage tank is also arranged in the middle of the bottom end of the inner side of the negative pressure sampling tube.

[0009] Furthermore, a protective shell is installed at the bottom end of the negative pressure sampling tube located outside the sampling needle tube, and a sealing plug is installed at the discharge port of the negative pressure sampling tube.

[0010] By adopting the above technical solution, after sampling is completed, the sealing plug can be opened to realize the convenient discharge of the sampled smoke oil in the negative pressure sampling tube.

[0011] Furthermore, the negative pressure sampling tube is a PET tube, and the threaded portion is formed on the negative pressure sampling tube.

[0012] By adopting the above technical solution, the interior of the negative pressure sampling tube is in a negative pressure state before sampling, so as to ensure convenient suction of the tobacco oil in the sampled tobacco cartridge.

[0013] Furthermore, the fixing screw sleeve is threadably connected to the negative pressure sampling tube, and the negative pressure sampling tube passes through the fixing screw sleeve.

[0014] By adopting the above technical solution, pinching the fixed screw sleeve and rotating the negative pressure sampling tube can ensure that the negative pressure sampling tube is easily moved downward relative to the fixed screw sleeve, so that the sampling needle tube can be inserted into a sampling cigarette cartridge on the market to extract and sample the cigarette oil.

[0015] Furthermore, one end of the short shaft is fixedly connected to the hook foot, and the other end of the short shaft is rotatably connected to the mounting groove.

[0016] By adopting the above technical solution, it can be ensured that the hook foot rotates synchronously with the short shaft.

[0017] Furthermore, the short shaft passes through the torsion spring, and the torsion spring is plugged into a socket reserved on the installation slot.

[0018] By adopting the above technical solution, the torsion spring can realize the resetting of the hook foot after the hook foot is lifted, so as to clamp the shell of the sampling cigarette cartridge with the help of the hook foot.

[0019] Furthermore, the top of the sampling needle tube is higher than the inner bottom surface of the negative pressure sampling tube, and the sampling needle tube is a stainless steel needle tube.

[0020] By adopting the above technical solution, such a design can ensure that the diluent is reliably stored at the bottom of the negative pressure sampling tube.

[0021] Furthermore, the cross swivel is bonded to the negative pressure sampling tube, and the cross swivel is composed of a fixed ring and four cross levers installed outside the fixed ring.

[0022] By adopting the above technical solution, the negative pressure sampling tube can be conveniently rotated and adjusted by turning the cross swivel.

[0023] (III) Beneficial effects

[0024] Compared with the prior art, the utility model has the following beneficial effects:

[0025] In order to solve the problem that the existing sampling device for detecting the content of components in liquid cigarette cartridges with anti-pollution can extract the smoke oil and clean the smoke oil adhering to the sampling port of the device when in use, the extraction head on the sampling device for detecting the content of components in liquid cigarette cartridges with anti-pollution structure is in the shape of a hollow cylinder inside, and it is impossible to directly extract the smoke oil in the sampled smoke cartridge, which is very inconvenient for the market supervisors on site. At the same time, because the smoke oil on the market is too viscous and does not meet the detection standard of the detector, the smoke oil extracted by the sampling device for detecting the content of components in liquid cigarette cartridges with anti-pollution structure needs to be diluted by the inspectors. The utility model solves the problem that the next step of detection can only be carried out in the long run, which makes the subsequent detection of the e-liquid more cumbersome. When extracting the e-liquid from the sampling cartridges on the market, the hooks are first clamped on the two sides outside the sampling cartridge under the action of the torsion spring and the short shaft to fix the sampling cartridge, and then the protective shell is opened, and the negative pressure sampling tube is rotated downward relative to the fixed screw sleeve by rotating the cross swivel, so that after the sampling needle tube is inserted into the sampling cartridge, the e-liquid can be automatically extracted into the negative pressure sampling tube. Since the diluent storage tank in the negative pressure sampling tube is pre-filled with diluent, the e-liquid can be directly diluted after the e-liquid is extracted, which is convenient for efficient detection of the e-liquid after extraction.

The hook foot 6 is now reset, so that the shell of the sampling cartridge can be clamped with the help of the hook foot 6. A threaded portion 8 is installed on the negative pressure sampling tube 2 at the position that cooperates with the fixed screw sleeve 4. A cross swivel 3 is also installed on the middle part of the outer part of the negative pressure sampling tube 2. By pinching the fixed screw sleeve 4 and rotating the negative pressure sampling tube 2, it can be ensured that the negative pressure sampling tube 2 is easily moved downward relative to the fixed screw sleeve 4, so that the sampling needle tube 7 can be inserted into the sampling cartridge on the market to extract and sample the tobacco oil. A diluent storage tank 9 is also provided in the middle part of the bottom end of the negative pressure sampling tube 2, and the diluent storage tank 9 is mainly used to store the diluent used to dilute the tobacco oil.

[0033] like Figure 1-Figure 3As shown, in this embodiment, the bottom end of the negative pressure sampling tube 2 is located outside the sampling needle tube 7 and a protective shell 5 is installed. The protective shell 5 can shield and protect the sampling needle tube 7 after sampling, thereby effectively avoiding contamination from sampling or the sampling needle. A sealing plug 1 is installed at the discharge port of the negative pressure sampling tube 2. When the sampling is completed, the sealing plug 1 is opened to realize the convenient discharge of the smoke oil in the negative pressure sampling tube 2 after sampling. The negative pressure sampling tube 2 is a PET tube, and the threaded portion 8 is formed on the negative pressure sampling tube 2.
