[0022] In order to make the purpose, technical solutions and advantages of the utility model clearer, the following further describes the utility model in detail with reference to the drawings and embodiments. Embodiment 1

[0023] As Figures 1-3 shown, the heat pump temperature control system integration module includes an inlay shell 2 having a cylindrical inner cavity. A panel 1 is integrally fixed to the edge of the outer port face of the inlay shell 2. The inlay shell 2 is fixed on the surface of the heat pump medium container through the panel 1. An inner extension pipe 3 is axially penetrated and fixed at the center position of the inner end face of the inlay shell 2. The diameter of the inner extension pipe 3 is smaller than the inner diameter of the inlay shell 2. A through port 31 is opened on the surface of the inner extension pipe 3. A plug board 4 is slidably fitted in the inner extension pipe 3. A spring is connected between the plug board 4 and the end of the inner extension pipe 3, so that the plug board 4 has a tendency to move towards the inlay shell 2;

[0024] The port part of the embedded shell 2 has an enlarged-diameter groove 6. The temperature sensor body 7 has an enlarged-diameter housing adapted to the enlarged-diameter groove 6. The edge of the enlarged-diameter housing has a positioning block 71, and the edge of the enlarged-diameter groove 6 has a positioning groove. The temperature sensor body 7 is axially inserted into the embedded shell 2, and the positioning block 71 is axially inserted into the positioning groove for axial alignment. The enlarged-diameter housing is adapted to be inserted into the enlarged-diameter groove 6. Four groups of screws are axially penetrated through the enlarged-diameter housing and threadedly connected to the inner end face of the enlarged-diameter groove 6 to fixedly connect the temperature sensor body 7 and the embedded shell 2. The monitoring component of the temperature sensor body 7 is inserted into the inner extension pipe 3, and the monitoring component of the temperature sensor body 7 abuts against the plug plate 4 to move, opening the through port 31. The medium in the container enters the inner extension pipe 3 through the through port 31, and the monitoring component of the temperature sensor body 7 monitors the temperature of the medium in real time;

[0025] When the temperature sensor body 7 fails and needs to be replaced, the detachable screws are used to axially pull out the temperature sensor body 7 from the embedded shell 2. As the temperature sensor body 7 is withdrawn, the plug plate 4 moves towards the embedded shell 2 under the action of elastic force. When the temperature sensor body 7 is taken out, the plug plate 4 blocks the through port 31 to prevent the medium from flowing out.

[0026] The axial adaptation length between the temperature sensor body 7 and the embedded shell 2 is greater than the axial length of the through port 31 opened by the plug plate 4. When the temperature sensor body 7 is assembled into the embedded shell 2, when the temperature sensor body 7 and the embedded shell 2 have been combined for a certain distance inside, the plug plate 4 moves to open the through port 31 and the medium flows out. Similarly, when the temperature sensor body 7 is disassembled, the plug plate 4 completely blocks the through port 31 before the temperature sensor body 7 is disengaged from the inner wall adaptation of the embedded shell 2.

[0027] The connection part between the inner extension pipe 3 and the embedded shell 2 has a necking part 5. The diameter of the plug plate 4 is greater than the inner diameter of the necking part 5, and the maximum movement range of the plug plate 4 is blocked and limited by the necking part 5.

[0028] Rubber sealing rings are provided on the inner wall of the embedded shell 2 and the surface of the plug plate 4 to improve the sealing effect between the plug plate 4 and the inner extension pipe 3, and between the embedded shell 2 and the temperature sensor body 7. Embodiment 2

[0029] The difference from Embodiment 1 lies in the axial fixing method between the temperature sensor body 7 and the embedded shell 2;

[0030] As Figures 4-5 shown, internal threads are provided on the inner side of the port part of the embedded shell 2, and external threads are provided on the outside of the temperature sensor body 7. Through the combination of the internal threads and the external threads, the temperature sensor body 7 is axially thread-assembled into the embedded shell 2;

[0031] The end face of the temperature sensor body 7 has a groove 72, and it is convenient to rotate the temperature sensor body 7 for thread adaptation with the embedded shell 2 by putting the hand into the groove 72.

[0032] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
