Description

Technical Field

[0001] The utility model belongs to the technical field of sensors, in particular to a dustproof and moisture-proof sensor. Background Art

[0002] A sensor (English name: transducer / sensor) is a detection device that can sense the information being measured and can transform the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording and control. The existence and development of sensors have given objects senses such as touch, taste and smell, making objects come alive. Sensors are an extension of human five senses. Sensors have the characteristics of miniaturization, digitization, intelligence, multi-function, systematization and networking. They are the primary link in realizing automatic detection and automatic control.

[0003] For example, a dustproof and moisture-proof sensor with publication number CN220871787U improves the heat dissipation holes to prevent damage to the internal components of the sensor. However, in daily use, the probe of the sensor is exposed to the outside and the sensor detects through the probe. The sensor does not provide dustproof and moisture-proof protection for the probe, resulting in a decrease in the accuracy of the sensor. In order to solve the above problems, a dustproof and moisture-proof sensor is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a dustproof and moisture-proof sensor to solve the above problems, comprising:

[0005] A sensor body, one side of which is fixedly mounted with a probe;

[0006] The protective sleeve is threadedly connected to the outer wall of the probe, a plurality of spring pieces are integrally arranged at the end of the protective sleeve, an anti-static dust-sticking pad is bonded to the inner wall of the spring piece, and a desiccant is fixedly installed on the inner wall of the spring piece.

[0007] Through the above technical solution, when the sensor is not needed, the protective sleeve is threadedly connected to the outer wall of the probe. At this time, the end of the probe is located inside the protective sleeve, and the moisture in the air is removed by the desiccant fixedly installed on the inner wall of the spring sheet, thereby protecting the probe from moisture. When the sensor needs to be used, the protective sleeve is rotated clockwise, and the protective sleeve moves to the left along the outer wall of the probe. During the movement, the spring sheet is pushed outward by the end of the probe. At this time, the anti-static sticky pad on the inner wall of the spring sheet contacts the outer wall of the probe, thereby removing the dust on the outer wall of the probe, thereby preventing the dust from affecting the accuracy of the sensor.

[0008] In a preferred embodiment, a threaded portion is provided in the middle of the probe, and an internal thread matching the threaded portion is provided at the lower end of the inner portion of the protective sleeve.

[0009] Through the above technical solution, the probe and the protective sleeve are connected by threads, which is convenient for installation and disassembly.

[0010] In a preferred embodiment, a ball is rotatably connected to the inner wall of the spring.

[0011] Through the above technical solution, the friction between the spring sheet and the probe is reduced by arranging the ball.

[0012] In a preferred embodiment, a limiting ring is welded to the outer wall of the protective sleeve on a side away from the shrapnel.

[0013] Through the above technical solution, by providing a limiting ring, on the one hand, the limiting ring is used to facilitate the rotation of the protective sleeve, and on the other hand, the limiting ring is used to fix the sensor on the object to be tested during the detection process.

[0014] In a preferred embodiment, the outer wall of the limiting ring is provided with friction patterns.

[0015] Through the above technical solution, the friction force of the limit ring is improved, making it easier to rotate the protective sleeve.

[0016] In a preferred embodiment, an observation window is provided on the middle outer wall of the protective sleeve.

[0017] With the above technical solution, the situation of the probe in the protective sleeve can be easily observed through the observation window.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effect of the utility model is: the utility model provides a dustproof and moisture-proof sensor.

[0019] 1. When the sensor is not needed, the protective sleeve is threadedly connected to the outer wall of the probe. At this time, the end of the probe is located inside the protective sleeve, and the desiccant fixed on the inner wall of the shrapnel removes moisture from the air, thereby protecting the probe from moisture.

[0020] 2. When the sensor needs to be used, rotate the protective sleeve clockwise, and the protective sleeve moves to the left along the outer wall of the probe. During the movement, the spring is pushed outward by the end of the probe. At this time, the anti-static sticky pad on the inner wall of the spring contacts the outer wall of the probe, thereby removing the dust on the outer wall of the probe, thereby preventing the dust from affecting the accuracy of the sensor.

[0027] Example:

[0028] A dust and moisture proof sensor, comprising:

[0029] The sensor body 1 has a probe 2 fixedly mounted on one side thereof, and a protective sleeve 3 which is threadedly connected to the outer wall of the probe 2. A threaded portion 21 is provided in the middle of the probe 2, and an internal thread matched with the threaded portion 21 is provided at the lower end of the inner part of the protective sleeve 3. The probe 2 and the protective sleeve 3 are connected by threads, which is convenient for installation and disassembly. An observation window is provided on the outer wall in the middle of the protective sleeve 3, through which the situation of the probe 2 in the protective sleeve 3 can be observed;

[0030] The end of the protective sleeve 3 is integrally provided with a plurality of spring pieces 31, and an anti-static dust-sticking pad 32 is bonded to the inner wall of the spring piece 31. When the sensor needs to be used, the protective sleeve 3 is rotated clockwise, and the protective sleeve 3 moves to the left along the outer wall of the probe 2. During the movement, the spring piece 31 is pushed outward by the end of the probe 2. At this time, the anti-static dust-sticking pad 32 on the inner wall of the spring piece 31 contacts the outer wall of the probe 2, thereby removing the dust contaminated by the outer wall of the probe 2, thereby preventing the dust from affecting the accuracy of the sensor. A desiccant 35 is fixedly installed on the inner wall of the spring piece 31, and a ball 33 is rotatably connected to the inner wall of the spring piece 31. The friction between the spring piece 31 and the probe 2 is reduced by setting the ball 33. When the sensor is not needed, the protective sleeve 3 is threadedly connected to the outer wall of the probe 2. At this time, the end of the probe 2 is located inside the protective sleeve 3, and the moisture in the air is removed by the desiccant 35 fixedly installed on the inner wall of the spring piece 31, thereby protecting the probe from moisture.

[0031] A limiting ring 34 is welded to the outer wall of the protective sleeve 3 on the side away from the spring piece 31. The limiting ring 34 is provided to facilitate the rotation of the protective sleeve 3 on the one hand, and to fix the sensor on the object to be tested through the limiting ring 34 during the detection process on the other hand. The outer wall of the limiting ring 34 is provided with friction patterns to increase the friction force of the limiting ring 34 and facilitate the rotation of the protective sleeve 3.

[0032] Working principle:

[0033] When the sensor is not needed, the protective sleeve 3 is threadedly connected to the outer wall of the probe 2. At this time, the end of the probe 2 is located inside the protective sleeve 3, and the moisture in the air is removed by the desiccant 35 fixedly installed on the inner wall of the spring clip 31, so as to provide moisture-proof protection for the probe. When the sensor needs to be used, the protective sleeve 3 is rotated clockwise, and the protective sleeve 3 moves to the left along the outer wall of the probe 2. During the movement, the spring clip 31 is pushed outward by the end of the probe 2. At this time, the anti-static sticky pad 32 on the inner wall of the spring clip 31 contacts the outer wall of the probe 2, so as to remove the dust on the outer wall of the probe 2, thereby preventing the dust from affecting the accuracy of the sensor.
