Description

TECHNICAL FIELD

[0001] The utility model relates to a smoking machine temperature measuring module, especially to a temperature measuring module for cigarette product temperature detection and suitable for flexible expansion linear smoking machine device. BACKGROUND

[0002] With the increasing demand for cigarette products, cigarettes have developed into many types, such as heat-not-burn cigarettes, ordinary cigarettes, etc. Regardless of the type of cigarette, smokers need to heat the cigarette to a certain temperature to produce smoke for smoking. Cigarette smoke contains many harmful substances, and higher smoke temperature will produce more harmful substances. At the same time, higher temperature will cause the taste of smoking to deteriorate, and in severe cases, it may cause the smoker's mouth to be scalded. When the cigarette burning temperature is low, it will also cause the cigarette smoke to release abnormally, which will lead to unqualified cigarettes. Therefore, flexible expansion smoking modules have emerged. It solves the problem that the traditional cigarette temperature detection device cannot support the simultaneous detection of the internal and external temperatures of the cigarette, the cigarette smoke outlet temperature, and the simultaneous detection of multiple types and multiple cigarettes. It cannot perform simple cigarette temperature detection and cannot detect other aspects of the cigarette.

[0003] The technical solution disclosed in the invention patent document with the application publication number CN 115389051 A and the name "A device for detecting the temperature of smoke generated by an electric heating cigarette during heating by a heating smoking set" has a temperature probe that can be inserted into the other end of the electric heating cigarette, which can detect the temperature of the functional section of the electric heating cigarette. The piston, temperature detection mounting seat, and mounting ring form a sealed space, and the smoke temperature sensor is arranged on the side wall of the space, and the probe head extends into the space to measure the temperature of the smoke drawn out. However, this technical solution has the following problems: 1) This scheme can only detect the temperature inside the cigarette axis position, and does not support temperature detection inside the radial position of the cigarette axis, resulting in inaccurate detection temperature; 2) This scheme cannot detect the temperature of the outer surface of the cigarette, and cannot meet the increasing detection demand.

[0004] The technical scheme disclosed in the utility model patent document with the publication number CN 217483701 U and the title "Cigarette smoking temperature detection device" is that a first temperature sensor, a second temperature sensor and a suction port for smoking a cigarette are arranged on the cigarette holder of the cigarette smoking temperature detection device, the first temperature sensor is used for detecting the temperature at the position where the filter tip contacts the smoker's lip surface, the second temperature sensor is used for detecting the smoke temperature at the proximal end of the filter tip, and the first temperature sensor and the second temperature sensor are both signal-connected with a data collector. The cigarette smoking temperature detection device clamps the cigarette by means of the cigarette holder, smokes the cigarette through the suction port, and the data detected by the first temperature sensor and the second temperature sensor is recognized and processed by the data collector, so as to simultaneously measure the temperature of the filter tip part that can be contacted by the smoker's lip surface and the smoke temperature entering the smoker's oral cavity. The technical scheme has the following problems: 1) This scheme cannot detect the temperature of each structure section inside the cigarette; 2) This scheme needs manual cigarette insertion positioning detection, and the detection efficiency is relatively low.
