Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic cigarette detection technology, and in particular to an electronic cigarette smoke sampling device. Background Technology
[0002] E-cigarettes are electronic devices that mimic traditional cigarettes, possessing a similar appearance, smoke, taste, and feel. They use rechargeable lithium polymer batteries to power an atomizer, turning substances like nicotine into vapor for users to inhale. E-cigarettes typically consist of a device and cartridges to satisfy users' cravings for these substances. As e-cigarettes gain wider acceptance among consumers, their safety and comfort are increasingly attracting attention.
[0003] According to the national standard for e-cigarettes (GB 41700-2022), 101 components of the atomized substances in e-cigarettes need to be tested. The current practice for e-cigarette quality supervision involves removing the cartridge and extracting the e-liquid for analysis. When testing atomized substances in e-cigarettes, the cartridge must first be disassembled and the e-liquid extracted before subsequent testing can begin. However, when dealing with sponge-type cartridge samples, after disassembling the cartridge, the sponge must be removed and the e-liquid squeezed out before further testing can proceed, resulting in low testing efficiency.
[0004] Because e-cigarettes ultimately produce vapor through high-temperature atomization, rather than directly analyzing the e-liquid, the main challenge lies in sampling this vapor. Currently, e-cigarette vapor sampling primarily uses rubber sleeves for suction, which makes vapor leakage easy and the extraction process difficult to control, directly impacting testing efficiency. Utility Model Content
[0005] In view of this, the purpose of this utility model is to provide an electronic cigarette smoke sampling device that is convenient and practical, facilitates control of the smoke extraction process, and improves detection efficiency.

Detailed Implementation
[0024] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.
[0025] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0026] like Figures 1-3 As shown, an electronic cigarette vapor sampling device includes a vapor collection chamber 300, a vapor analyzer 400, a mouthpiece clamp, and a tail gas collection device 500. A detection inlet tube 310 connects the vapor collection chamber 300 to the vapor analyzer, a vapor suction tube 170 connects the vapor collection chamber to the mouthpiece clamp, and an exhaust tube 320 connects the vapor collection chamber to the tail gas collection device. Air pumps, a first air pump 321 and a second air pump 311, are respectively installed on the exhaust tube 321 and the detection inlet tube 310. The first air pump 321 draws vapor from the electronic cigarette into the vapor collection chamber 300. After the vapor is collected in the vapor collection chamber 300, the second air pump 311 sends the vapor into the vapor analyzer for analysis. This electronic cigarette smoke sampling device creates a relatively enclosed space and is equipped with an exhaust gas collection device to treat the emitted smoke, reducing the impact of smoke leakage on the laboratory environment; it is convenient and practical, and the smoke extraction process is easy to control, directly affecting the testing efficiency.
[0027] In this embodiment, the mouthpiece clamp includes a sealed box 100, the front of which is sealed by a rubber sheet 110. A mouthpiece-shaped mouthpiece clamp 120 is provided on the rubber sheet, and a tightening ring 130 is provided around the mouthpiece clamp. A tightening strap 140 is provided inside the tightening ring. This utility model of an electronic cigarette mouthpiece clamp utilizes the tightening strap to shrink the mouthpiece clamp, thereby clamping the electronic cigarette mouthpiece. It is applicable to mouthpieces of various shapes (such as round, oval, and flat square mouthpieces), has good versatility, requires no customized interface, reduces testing costs, improves testing efficiency, and solves the compatibility problem of different electronic cigarette mouthpieces.
[0028] In this embodiment, the tightening ring has a notch on the side facing the inside of the box, and the two ends of the tightening band cross at the notch and then pass through the notch. The box is provided with a tightening device for pulling the two ends of the tightening band.
[0029] In this embodiment, the tightening device includes a motor 150 located inside the housing. A take-up shaft 151 is coaxially connected to the main shaft of the motor. One end of the tightening strap is wound around the take-up shaft, and the other end of the tightening strap passes over two fixed pulleys 160 and is also wound around the take-up shaft. When the motor rotates forward, the take-up shaft 151 simultaneously winds up both ends of the tightening strap to tighten the mouthpiece clamp. When the motor rotates in reverse, the take-up shaft 151 simultaneously loosens both ends of the tightening strap to loosen the mouthpiece clamp. The mouthpiece clamp can automatically open due to the elasticity of the rubber cloth. If the elasticity is insufficient, the mouthpiece clamp can also be opened manually.
[0030] In this embodiment, one of the fixed pulleys is located inside the box on the other side, and the other fixed pulley is located below the winding shaft.
[0031] In this embodiment, a smoke extraction pipe 170 is provided on the top or rear side of the box. The smoke extraction pipe 170 draws air in, creating negative pressure inside the box, which draws smoke out from the mouthpiece of the electronic cigarette.
[0032] In this embodiment, the bottom front side of the box is provided with a base plate 180 extending forward, and the front end of the base plate is provided with a support frame 181 for supporting the electronic cigarette. The support frame 181 is used to support the front end of the electronic cigarette to prevent the front end of the electronic cigarette from swinging down and to keep the electronic cigarette as horizontal as possible; the upper part of the support frame is V-shaped.
[0033] In this embodiment, a control switch is provided on one side of the outer side of the box. There are three control switches: one is the main switch, one controls the forward rotation of the motor, and the other controls the reverse rotation of the motor.
[0034] In this embodiment, the smoke collection chamber is also connected to a sampling tube 330 for connection to an external sampling device.
[0035] In this embodiment, the detection inlet tube, flue gas suction tube, extraction tube and sampling tube are all equipped with shut-off valves, namely shut-off valve A312, shut-off valve B171, shut-off valve C322 and shut-off valve D331.
[0036] In this embodiment, the exhaust pipe is also equipped with a check valve 323 that only allows gas to flow unidirectionally from the smoke collection chamber to the exhaust gas collection device.
[0037] In this embodiment, the smoke extraction pipe is also equipped with a throttling valve 172 and a pressure regulating valve 173. Since the smoke concentration is affected by the extraction speed and pressure, the throttling valve 172 and the pressure regulating valve 173 are provided. By adjusting the pressure and flow rate of the extracted smoke, the smoking process can be simulated to obtain a smoke concentration that is more in line with reality.
[0038] In this embodiment, the exhaust gas collection device can be a collection bag or a collection box. The exhaust gas collection device is connected to an exhaust pipe. The cavity of the exhaust gas collection device contains a sponge, filter element, etc. to filter atomized substances. The exhaust gas collection device is existing technology, and its structure and principle will not be described in detail here.
[0039] The working process of this electronic cigarette vapor sampling device:
[0040] 1. Place the e-cigarette mouthpiece into the mouthpiece clamp of the mouthpiece holder, and control the mouthpiece clamp to retract and hold the e-cigarette mouthpiece.
[0041] 2. Close the detection inlet tube and sampling tube, open the smoke suction tube and extraction tube, start the first air pump to start pre-suction, draw the e-cigarette smoke into the smoke collection chamber, and at the same time expel the air in the device to avoid affecting the concentration.
[0042] 3. After a period of pre-vacuuming, the air inside the device will be completely expelled.
[0043] 4. Adjust the throttle valve and pressure regulating valve to control the suction pressure and flow rate to start sampling suction;
[0044] 5. After sampling and aspiration for a period of time, the smoke gas previously aspirated in the smoke collection chamber is basically replaced by newly aspirated smoke gas, and the first air pump is turned off.
[0045] 6. Open the sample inlet tube, close the sampling tube, the extraction tube, and the flue gas suction tube, start the second air pump, and deliver a certain amount of flue gas into the flue gas analyzer for detection.
