Description

Technical Field

[0001] The utility model relates to the field of temperature probes, in particular to a temperature probe that is waterproof and permeable. Background Art

[0002] A temperature probe is a device used to measure temperature, converting temperature changes into an electrical signal for quantitative analysis. Widely used in industry, healthcare, environmental monitoring, and other fields, temperature probes can measure the temperature of gases, liquids, and solids. Contact temperature probes require physical contact with the object being measured, achieving thermal equilibrium through conduction or convection, allowing the probe's reading to directly represent the object's temperature. Non-contact temperature probes, on the other hand, measure temperature through heat radiation or convection from the medium without requiring contact.

[0003] Temperature probes typically contain sensitive electronic components. If water enters the probe, it may cause a short circuit or damage the circuit board, affecting the normal operation of the probe. Water molecules will change the heat conduction characteristics between the probe and the measured medium, thereby affecting the accuracy of the temperature reading. To ensure the water-proof function of the temperature probe, waterproof materials such as high-strength plastic or rubber are used to manufacture the probe housing to ensure that water molecules cannot penetrate the probe interior. Sealing rings or sealants are used at the joints of the probe to prevent moisture penetration.

[0004] In the existing technology, waterproof materials and sealing rings are generally used to protect temperature probes from water seepage. However, when the temperature probe is idle, the detection end lacks protection and will be corroded by the humid environment, resulting in water infiltration. At the same time, the lack of positioning protection function will increase the risk of damage when it is subjected to external impact. Therefore, a waterproof temperature probe is proposed to solve the above problems. Summary of the Invention

[0005] In order to make up for the above shortcomings, the utility model provides a waterproof and permeable temperature probe, which aims to improve the problem that the waterproof and permeable temperature probe in the existing technology lacks the protection function for the probe, causing it to be corroded by moisture in a humid environment and subjected to external collision and impact, resulting in an increased risk of damage.

[0032] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figure 1-Figure 3The utility model provides an embodiment: a temperature probe capable of waterproof penetration, comprising a temperature probe body 1, a threaded groove 2 is provided on the surface of the temperature probe body 1, a fixing ring 3 is threadedly connected to the inner wall of the threaded groove 2, a protective tube 4 is fixedly connected to the outer wall of the fixing ring 3, the protective tube 4 is sleeved on the outer wall of the temperature probe body 1 to provide protection for the temperature probe body 1, a positioning frame 5 is fixedly connected to the inner wall of the protective tube 4, two groups of positioning frames 5 are provided, and the two groups of positioning frames 5 are mirror-imaged with the center point of the protective tube 4 as the axis of symmetry, and the positioning frames 5 are arranged in a U shape. The positioning frame 5 near one end of the thread groove 2 is sealed, and the positioning frame 5 is convenient for inserting and placing the desiccant bag 7. A through hole 6 is opened through the surface of the positioning frame 5, and a desiccant bag 7 is provided on the inner surface of the positioning frame 5. The desiccant bag 7 is made of a non-woven bag containing desiccant particles. A sealing cover 12 is provided on the inner surface of the protective tube 4. The sealing cover 12 seals and blocks the opening of the protective tube 4, and an inner concave handle is provided on the surface of the sealing cover 12 for easy insertion of fingers for extraction. A protective component is provided on the inner wall of the protective tube 4, and a sealing component is provided on the surface of the sealing cover 12.

[0034] Reference Figure 4-Figure 6 The outer surface of the sealing cover 12 is adapted to the inner surface of the protective tube 4. The protective assembly includes a telescopic rod 8. The end of the telescopic rod 8 away from the protective clip 10 is fixedly connected to the inner wall of the protective tube 4. The outer wall of the telescopic rod 8 is provided with a spring 9. One end of the spring 9 is fixedly connected to the inner wall of the protective tube 4. The other end of the spring 9 is fixedly connected to the outer surface of the protective clip 10. The movable end of the telescopic rod 8 is fixedly connected to the protective clip 10. The protective clip 10 is provided in two groups, and the two groups of protective clips 10 are mirror-imaged with the center point of the protective tube 4 as the symmetry axis. The two groups of protective clips 10 are both arranged through multiple groups of equally spaced telescopic rods. The retracted rod 8 and the spring 9 provide support and limitation. The elasticity of the spring 9 brings the two sets of protective clips 10 closer to each other. The inner surface of the protective clip 10 is fixedly connected with a sponge pad 11. The sponge pad 11 contacts the outer wall of the temperature probe body 1. The softness of the sponge pad 11 will not cause wear on the surface of the temperature probe body 1. The sealing assembly includes an annular groove 13. The annular groove 13 is opened on the outer wall of the sealing cover 12. The inner wall of the annular groove 13 is adapted to the outer wall of the sealing ring 14. The inner wall of the annular groove 13 is provided with a sealing ring 14. The sealing ring 14 improves the sealing degree of the sealing cover 12 to the protective tube 4.

[0035] Reference Figure 3 and Figure 6The inner wall of the protective tube 4 is fixedly connected with a sealing strip 16, and the outer surface of the sealing cover 12 is provided with a groove 15. The inner wall of the groove 15 is adapted to the outer wall of the sealing strip 16. There are several groups of sealing strips 16 and grooves 15, and several groups of sealing strips 16 and grooves 15 are distributed in a circular array with the center point of the protective tube 4 as the axis of symmetry. The setting of the sealing strips 16 and grooves 15 can increase the friction between the sealing cover 12 and the protective tube 4 and reduce the risk of the sealing cover 12 falling off the protective tube 4.

[0036] Working principle: The temperature probe body 1 detects temperature. When the temperature probe body 1 is in an idle state, the protective tube 4 is first put on the outer wall of the temperature probe body 1. At this time, the two sets of sponge pads 11 will contact the outer wall of the temperature probe body 1. The spring 9 is loaded and drives the telescopic rod 8 to compress synchronously until the fixing ring 3 approaches the thread groove 2. The fixing ring 3 is then screwed into the inner part of the thread groove 2 to fix the protective tube 4 on the temperature probe body 1. When the protective tube 4 is in a stationary state on the temperature probe body 1, the elastic force of the spring 9 is restored, allowing the two sets of protective clips 10 to fit and fix the temperature probe body 1. After the desiccant bag 7 is inserted into the interior of the positioning frame 5, the groove 15 of the sealing cover 12 is aligned with the corresponding sealing strip 16 and inserted until the sealing cover 12 cannot move, thereby sealing the opening of the protective tube 4. This prevents the temperature probe body 1 from being affected by moisture and causing water seepage when placed in a humid environment. At the same time, it provides positioning protection for the temperature probe body 1 to prevent damage caused by impact, thereby ensuring the accuracy of subsequent detection of the temperature probe body 1.
