Description

Technical Field

[0001] The utility model relates to the technical field of probe waterproof structures, in particular to a double waterproof structure of a wired probe. Background Art

[0002] A temperature probe with a wire is a sensor used to measure the temperature of an object. It usually consists of a probe and a measuring instrument. The probe is usually a metal rod, one end of which is connected to the measuring instrument and the other end can be inserted into the object. When the probe is inserted into the object, the temperature of the object will affect the resistance value of the probe, thereby changing the output signal of the measuring instrument. The measuring instrument can be a digital thermometer, an analog thermometer or other type of temperature measuring device. Temperature probes are usually used to measure the temperature of liquids, gases and solids, such as in industry, science and medical fields. After being used in a high temperature environment, the existing probe with a wire needs to be rinsed with cold water, which will cause the pipe mouth and the Teflon wire to cool and shrink after high temperature, and a gap will be created, causing water to enter the probe, causing the temperature sensor to change its resistance value due to moisture, affecting the accuracy of the detection. To this end, the utility model proposes a double waterproof structure of a probe with a wire. Utility Model Content

[0003] The purpose of the utility model is to address the problem in the background technology that a wired probe needs to be placed in cold water for flushing after being used in a high-temperature environment, which will cause the pipe mouth and the Teflon line to cool and shrink after high temperature, and create gaps that allow water to enter the probe, causing the temperature sensor to change its resistance value due to moisture, thereby affecting the detection accuracy. A wired probe with a double waterproof structure is proposed.

[0004] The technical solution of the utility model is as follows: a double waterproof structure of a wired probe, comprising: a stainless steel tube, wherein two high-temperature resistant Teflon wires are arranged inside the stainless steel tube; a temperature sensor is arranged at one end inside the stainless steel tube, wherein two end pins of the temperature sensor are welded to the high-temperature resistant Teflon wire; an insulating glass fiber tube is sleeved on the welding position of the high-temperature resistant Teflon wire and the temperature sensor, wherein the insulating glass fiber tube is fixedly sleeved with the stainless steel tube; a sleeve is sleeved on the high-temperature resistant Teflon wire, wherein the sleeve is fixedly sleeved with the stainless steel tube; and a waterproof ring is located at one end of the insulating glass fiber tube for waterproofing the probe, wherein the waterproof ring is arranged between the stainless steel tube and the high-temperature resistant Teflon wire.

[0005] Optionally, the joint between the stainless steel tube and the sleeve is provided with a roller seal.

[0006] Optionally, a stainless steel handle is fixedly sleeved on the riveted portion of the stainless steel tube.

[0007] Optionally, the stainless steel tube and the stainless steel handle are made of 304 stainless steel or 316 stainless steel.

[0008] Optionally, the sleeve may be a high temperature resistant plastic tube or a Teflon tube.

[0009] Optionally, the waterproof ring is made of silicone.

[0010] Compared with the prior art, the utility model has the following beneficial technical effects:

[0011] The utility model forms a first waterproof layer by riveting and sealing the joint of the stainless steel tube and the sleeve, and forms a second waterproof layer by arranging a waterproof ring at the welding joint of the temperature sensor and the high-temperature resistant Teflon wire. The utility model can improve the sealing degree inside the probe and ensure that after the probe wire is exposed to high temperature or cold water for a long time, water cannot enter through the gap due to the influence of temperature, and the internal sensor is prevented from being affected, thereby improving the accuracy of sensor detection and increasing the service life.

[0021] like Figure 1 and Figure 2 As shown, the utility model proposes a double waterproof structure of a wired probe, comprising: a stainless steel tube 1, wherein two high-temperature resistant Teflon wires 2 are arranged inside the stainless steel tube 1; a temperature sensor 3 arranged at one end inside the stainless steel tube 1, wherein both end pins of the temperature sensor 3 are welded to the high-temperature resistant Teflon wire 2, so that the connection is more stable; an insulating glass fiber tube 4 sleeved at the welding place between the high-temperature resistant Teflon wire 2 and the temperature sensor 3, wherein the insulating glass fiber tube 4 is fixedly sleeved with the stainless steel tube 1, so as to prevent current leakage and short circuit, thereby improving the safety and reliability of the circuit; a sleeve 5 sleeved on the high-temperature resistant Teflon wire 2, wherein the sleeve 5 is fixedly sleeved with the stainless steel tube 1, thereby forming a first waterproofing layer; a waterproofing ring 6 located at one end of the insulating glass fiber tube 4 for waterproofing the probe, wherein the waterproofing ring 6 is arranged between the stainless steel tube 1 and the high-temperature resistant Teflon wire 2, thereby forming a second waterproofing layer, and the two waterproofing layers can improve the sealing performance inside the probe, thereby achieving a better waterproofing effect.

[0022] Furthermore, the joint between the stainless steel tube 1 and the sleeve 5 is provided with a roll-sealed configuration, which enables the stainless steel tube 1 to fit tightly with the sleeve 5 and prevents cold water from entering the interior of the probe through the gap during flushing.

[0023] like Figure 1 As shown, a stainless steel handle 7 is fixedly sleeved on the riveted part of the stainless steel tube 1, which can cover the rolled seal between the stainless steel tube 1 and the sleeve 5, making it convenient to take and use.

[0024] Secondly, the stainless steel tube 1 and the stainless steel handle 7 are made of 304 stainless steel or 316 stainless steel. In particular, 304 stainless steel has good corrosion resistance and can be used in a variety of environments. At the same time, 304 or 316 stainless steel is a safe and hygienic material and will not cause harm to human health.

[0025] Furthermore, the sleeve 5 can be a high-temperature resistant plastic tube or a Teflon tube, both of which have good high-temperature resistance and can be used for a long time in a high-temperature environment without deformation or aging. At the same time, they have good sealing performance and can effectively prevent leakage of liquid and gas to ensure the normal operation of the system.

[0026] In addition, the waterproof ring 6 is made of silicone and is provided with two perforations. Silicone has good waterproof properties and can effectively prevent the intrusion of water and moisture, thus protecting the device from damage.

[0027] The working principle of this embodiment is as follows: firstly, the high temperature resistant Teflon wire 2 is passed through the two holes of the waterproof ring 6, then the high temperature resistant Teflon wire 2 is welded to the two end pins of the temperature sensor 3, and the insulating glass fiber tube 4 is sleeved at the welding point. Subsequently, a sleeve 5 is sleeved on the outer wall of the other end of the high temperature resistant Teflon wire 2.

[0028] Furthermore, the welded high temperature resistant Teflon wire 2 and waterproof ring 6 are inserted into the interior of the stainless steel tube 1 from one end of the stainless steel tube 1, and the sleeve 5 is located at the end of the stainless steel tube 1. The sleeve joint of the stainless steel tube 1 and the sleeve 5 is then riveted and sealed, which can improve the sealing degree inside the probe and ensure that the probe line is not affected by temperature after being flushed with high temperature or cold water for a long time, and prevent the internal sensor from being affected, thereby improving the accuracy of sensor detection and extending the service life.

[0029] The above-mentioned specific embodiments are only several optional embodiments of the present invention.
