Nozzle temperature measuring device

Abstract

A cigarette tip stick temperature measuring device, comprising a device platform, a cigarette heater supporting and starting device, a suction main body, and a temperature measuring part; the cigarette heater supporting and starting device, a suction main body, and a temperature measuring part are arranged on the device platform Above; the temperature measuring part cooperates with the cigarette heater supporting and starting device, and the suction body to measure the temperature of the mouth stick of the cigarette; the suction body is a three-way structure, and the left end of the three-way structure is inserted into the mouth of the cigarette The rod is kept stable and sealed, the right end is inserted into the temperature measuring element and kept stable and sealed, and the lower end is connected to the smoking machine for cigarette smoking. The invention can realize temperature measurement without affecting the suction, and avoids inaccurate temperature measurement caused by gas leakage; it can be used for simultaneous measurement of the temperature of multiple cigarette tip sticks, especially heat-not-burn cigarette tip sticks, and improves the measurement efficiency; it can be automatically controlled The depth of the thermocouple inserted into the nozzle rod improves the convenience of operation, and the repeatability of the insertion position ensures the stability of the test results.

Description

technical field [0001] The invention belongs to the field of cigarette temperature detection, and relates to a device which can be used for measuring the temperature of a cigarette tip rod. Background technique [0002] In addition to traditional cigarettes, heat-not-burn cigarettes are currently on the rise, and there is a huge difference between the mouthpiece of non-burn cigarettes and traditional filter sticks. First of all, from a functional point of view, the main function of traditional cigarette filter rods is to filter harmful substances, while the main function of the mouthpiece of heat-not-burn cigarettes is to cool down; from a structural point of view, traditional cigarette filter rods are generally a single tow-filled structure , while most of the current heat-not-burn cigarette tip rods are multi-segment composite structures, and their materials are not pure fiber tows. Therefore, in the research on the mouth stick of non-burning cigarettes, the temperature m...

AI Technical Summary

Problems solved by technology

Traditional cigarettes have no need for temperature measurement of the mouth stick, but focus on the temperature measurement of the burning section of the cigarette. Generally, the smoke temperature of the shredded tobacco section is obtained by inserting a fine thermocouple in the radial direction of the cigarette. These methods or devices cannot be used for different purposes. The measurement of the temperature of the tip rod of the burning cigarette is mainly due to the following problems: 1. The multi-section structure of the non-burning cigarette is relatively hard, and it is not easy to insert the fine thermocouple from the radial direction; 2. The insertion point of the thermocouple is difficult to keep sealed. Entering will lead to a deviation in the measured temperature; 3. Traditional cigarettes burn, and the cigarettes are very light and do not need support. When smoking non-combustible cigarettes, a special heating device is required to heat the cut tobacco section, and the heating device needs support; 4. The traditional device only needs to be supported once. Measuring the temperature of one cigarette cannot be used for simultaneous measurement of multiple cigarettes, and cannot meet the batch measurement requirements for the development of cooling materials for non-burning cigarette tip rods; 5. The insertion position of the thermocouple has not been automatically and accurately controlled
