[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] Please refer to the attached Figure 1-6 As shown, a photoelectric liquid level detection sensor provided by an embodiment of the utility model includes a front shell 10, a rear shell 20 and an infrared detection component 30, wherein a liquid inlet pipe joint 11 and a liquid outlet pipe joint 12 are provided on both sides of the front shell 10, and a liquid flow groove 13 is provided on the front shell 10, wherein the liquid inlet pipe joint 11 is connected to one end of the liquid flow groove 13, and the liquid outlet pipe joint 12 is connected to the other end of the liquid flow groove 13, and the liquid inlet pipe joint 11 and the liquid outlet pipe joint 12 are integrally designed with the front shell 10; a first mounting portion 21 and a second mounting portion 22 are provided on both sides of the rear shell 20, and a lens portion 24 and a mounting groove 23 are provided on the rear shell 20, wherein the infrared detection component 30 is arranged in the mounting groove 23, and the first mounting portion 21 and the second mounting portion 22 are integrally designed with the rear shell 20; the front shell 10 and the rear shell 20 are covered with each other to form a closed whole, and the lens portion 24 extends into the liquid flow groove 13.

[0027] The front housing 10 is provided with a step portion 14 on one side facing the rear housing 20, and the rear housing 20 is provided with a sealing portion 25 at a position corresponding to the step portion 14 on one side facing the front housing 10. When the front housing 10 and the rear housing 20 are covered, the sealing portion 25 abuts against the step portion 14, and the sealing portion 25 and the rear housing 20 are designed in an integrated manner. Optionally, the step portion 14 includes a first step 141 and a second step 142, and the sealing portion 25 includes a first sealing ring 251 corresponding to the first step 141 and a second sealing ring 252 corresponding to the second step 142. The material of the sealing portion 25 is a soft rubber material, and the material of the rear housing 20 is a hard transparent rubber material. During manufacturing, the integrated rear housing 20 including the first mounting portion 21 and the second mounting portion 22 is first manufactured with a hard transparent rubber material, and then the manufactured rear housing 20 is placed in a preset mold, and the sealing portion 25 is manufactured by a secondary molding process.
