[0019] In order to make the purpose, technical scheme of the utility model to be clear, complete description, and the advantage is more clear and clear, following combining the drawing to the utility model embodiment further detailed explanation.Should understand, the specific embodiment described here is a part of the embodiment of the utility model, instead of all the embodiment, just to explain the embodiment of the utility model, and does not use to limit the embodiment of the utility model, and all other embodiments obtained by the ordinary skill in the art without doing the creative labor are within the scope of the utility model protection.

[0020] Please refer to Figs. 1 to 4 The utility model provides a technical scheme: embedded temperature and humidity transmitter, including:

[0021] The outer casing 1 has an extension rod 2 fixed to its bottom. A brush 5 is installed inside the extension rod 2. A through groove 4 is formed inside the extension rod 2, and a probe 3 is inserted into the through groove 4. After being inserted into the through groove 4, the probe 3 contacts the rubber pad on the surface of the moving ring 7, allowing the probe 3 to move within the through groove 4. A dust collection trough 12 is formed inside the through groove 4, located at the bottom of the brush 5 and the extension rod 2. A moving groove 6 is formed within the through groove 4, and the moving ring 7 is located within the moving groove 6, allowing the moving ring 7 to move within the moving groove 6. A spring 10 is installed within the moving groove 6, with one end of the spring 10 connected to the moving ring 7. The surface of ring 7 is connected to the inner wall of moving groove 6 at the other end. A limiting groove 8 is opened inside the through groove 4. Connecting rod 9 is located in limiting groove 8 and can move in limiting groove 8. Connecting rod 9 moves with moving ring 7. Rubber pad is provided on the surface of moving ring 7. Moving ring 7 is provided in through groove 4. Connecting rod 9 is fixed at the end of moving ring 7. Contact ring 11 is fixed at the end of connecting rod 9. Connecting rod 9 moves in limiting groove 8. Connecting rod 9 drives contact ring 11 to move. Contact ring 11 moves on the surface of brush 5 and knocks off the dust on the surface of brush 5, so that the dust falls from dust collection groove 12.

[0022] When not in use, probe 3 is inserted into the through groove 4 inside extension rod 2. A brush 5 is installed inside the through groove 4. After probe 3 is inserted into the through groove 4, the end of probe 3 will contact the brush 5. The brush 5 will remove dust from the end of probe 3. When probe 3 is inserted into the through groove 4, it first contacts the moving ring 7. The surface of the moving ring 7 is provided with a rubber pad, so that the moving ring 7 moves with probe 3. The moving ring 7 drives the connecting rod 9 to move. The connecting rod 9 moves in the limiting groove 8. The connecting rod 9 drives the contact ring 11 to move. The contact ring 11 moves on the surface of brush 5, knocking off the dust on the surface of brush 5, so that the dust falls into the dust collection groove 12. After the moving ring 7 is held against the end of the moving groove 6, the moving ring 7 stops moving as probe 3 continues to move. The moving ring 7 returns to the initial position under the push of spring 10.
