This utility model discloses a TPE hollow wire heating hose, belonging to the technical field of heating hoses. The TPE hollow wire heating hose includes a tube body, with a stainless steel tube fixedly installed on the surface of the tube body. A temperature sensor is detachably installed inside the stainless steel tube. A snap-fit ​​mechanism is fixedly installed inside the stainless steel tube, and a limiting mechanism is fixedly installed on the surface of the stainless steel tube. The main body of the tube is made of Teflon tubing, which has good flexibility and high-temperature resistance, reducing carbonization. The outer layer of the Teflon tubing uses four layers of steel wire braided mesh to ensure the working pressure of the hose. The outer layer of the steel wire braided mesh uses four layers of thermal insulation cotton, which has good insulation and uniform heat conduction. The snap-fit ​​mechanism connects the stainless steel tube and the temperature sensor. During replacement, the snap-fit ​​plate can be removed from the snap-fit ​​groove without affecting the sealing performance. The limiting mechanism limits the snap-fit ​​plate, allowing the temperature sensor to operate for extended periods.

The utility model belongs to the field of suction guns, particularly relates to an intelligent digital display suction gun, and aims to solve the problems that a capillary tube of an existing traditional suction gun is usually arranged at an air inlet of a suction gun tube, the capillary tube of the suction gun is easily blocked in the actual use process, the measurement effect is further influenced, the capillary tube is inconvenient to disassemble, clean or replace, the maintenance is inconvenient, and the work efficiency is high. According to the scheme, the device comprises a handle, one end of the handle is communicated with a probe pipeline, the end, away from the handle, of the probe pipeline is communicated with a connecting piece, the end, away from the probe pipeline, of the connecting piece is detachably connected with a filter head, and the filter head is used for filtering moisture and dust of sucked gas. When the gas filter is used, impurities such as water, oil mist, dust and the like in gas can be filtered out, so that the accuracy of subsequent detection is ensured, the blockage of a rear pipeline is avoided, the aim of conveniently disassembling the filter head is fulfilled, and the filter head which is used for a long time can be cleaned or replaced.

The utility model relates to a carbon dioxide air-conditioning insecticidal system which comprises an air-conditioning chamber, the inner space of the air-conditioning chamber is divided into a pressure chamber and a buffer chamber by a first airtight gate, the buffer chamber is further provided with a second airtight gate, and a first electromagnetic pressure release valve is arranged between the pressure chamber and the buffer chamber. The buffer chamber is provided with a second electromagnetic pressure release valve used for being communicated with the atmosphere, an air inlet of the compressor is connected with the carbon dioxide air source, the pressure chamber and the buffer chamber through corresponding air inlet pipelines, and the pressure chamber is provided with a second electromagnetic pressure release valve used for being communicated with the atmosphere; air outlets of the compressors are connected with the atmosphere and the pressure chamber through corresponding air outlet pipelines; and the carbon dioxide air-conditioning insecticidal system further comprises a stored object moving tray for transferring stored objects between the pressure chamber and the buffer chamber. According to the utility model, the technical problems of carbon dioxide waste and greenhouse effect caused by direct emission of carbon dioxide after each use in the prior art are solved.
