Description

Technical Field

[0001] This utility model relates to the field of waterproof temperature sensor technology, and in particular to a waterproof temperature sensor probe with a silicone plug. Background Technology

[0002] Waterproof thermometers are temperature measurement tools specifically designed for special environments. They are waterproof and typically equipped with stainless steel probes. These instruments generally feature temperature hold and extreme value memory functions, with probe response times as fast as 3 seconds. Their waterproof rating exceeds IP67 standards, and they are widely used in HACCP system temperature monitoring in food processing, warehousing, and logistics scenarios.

[0003] Stainless steel tube NTC temperature sensor probes typically use heat-shrink silicone tubing attached to a wire, which is then rolled to the steel tube opening to achieve a certain degree of waterproofing. However, existing stainless steel tube NTC temperature sensor probes usually use stainless steel mesh wire, and the silicone tubing and wire cannot be tightly bonded, resulting in compromised waterproofing performance. Utility Model Content

[0004] The purpose of this invention is to provide a waterproof temperature sensor probe with a silicone plug, which solves the problem that existing stainless steel tube NTC temperature sensor probes usually use stainless steel wire mesh, and the silicone tube and wire cannot be tightly bonded, which leads to the inability to guarantee the waterproof performance of the product.

[0005] To achieve the above objectives, a waterproof temperature sensor probe with a silicone plug is provided, comprising: a water temperature sensor probe body, a probe head fixedly connected to one end of the water temperature sensor probe body, core wires fixedly connected to both sides of the interior of the water temperature sensor probe body, a silicone plug inserted into one end of the water temperature sensor probe body, through holes formed on both sides of the interior of the silicone plug, a sealing cover fixedly connected to one end of the through hole, the core wires passing through the through holes and the sealing cover respectively, and a lead wire fixedly connected to one end of the core wires.

[0006] As a preferred technical solution of this utility model, a flip-over rubber layer is fixedly connected to the outer side of the middle part of the silicone plug, and the flip-over rubber layer is flipped to cover the outside of the water temperature sensor probe body.

[0007] As a preferred embodiment of this utility model, one end of the sealing cover is fixedly connected to a rubber tube, and the rubber tube is sleeved on the outside of the core wire.

[0008] As a preferred embodiment of this utility model, two arc-shaped grooves are formed inside the water temperature sensor probe body near the silicone plug.

[0009] As a preferred embodiment of this utility model, one end of the silicone plug is fixedly connected to two rubber rings, and the rubber rings and the arc-shaped groove are in arc-shaped fit.

[0010] The above-mentioned solution has the following beneficial effects: This invention comprises a silicone plug, a core wire, a sealing cover, and rubber rings. One end of the silicone plug is inserted into the water temperature sensor probe body. During insertion, the core wire passes through a through hole and then through the sealing cover. This ensures that the core wire does not affect its use while achieving a high-strength waterproof effect. Two rubber rings at one end of the silicone plug fit into the arc-shaped groove on the inner wall of the water temperature sensor probe body, achieving a sealing effect. Adding a silicone plug between the steel pipe and the lead wire ensures the internal sealing of the product, solves the waterproof problem, and guarantees the normal electrical performance of the product.

[0011] This invention comprises a rubber tube, a core wire, a lead wire, and a flip-over rubber layer. The core wire expands the rubber tube, which is then firmly and tightly bonded to the core wire, achieving a high-strength waterproof effect. The core wire and lead wire are then connected. Finally, the flip-over rubber layer is fitted onto the connection between the water temperature sensor probe body and the silicone plug using a silicone flip-over mechanism, further blocking water from the source. This structure achieves highly efficient waterproofing.

[0012] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0016] Reference Figure 1-4 This utility model discloses a waterproof temperature sensor probe with a silicone plug, comprising: a water temperature sensor probe body 1, a probe head 2 fixedly connected to one end of the water temperature sensor probe body 1, and core wires 3 fixedly connected to both sides of the interior of the water temperature sensor probe body 1. The core wires 3 are passed through through holes 9 and then through a sealing cover 7, thereby ensuring that the core wires 3 do not affect use while achieving a high-strength waterproof effect. A silicone plug 4 is inserted into one end of the water temperature sensor probe body 1. The silicone plug 4 is connected to the water temperature sensor probe body 1 by inserting one end of the silicone plug 4 into it. Through holes 9 are provided on both sides of the interior of the silicone plug 4. A sealing cover 7 is fixedly connected to one end of the through hole 9. The core wires 3 pass through the through hole 9 and the sealing cover 7 respectively. A lead wire 6 is fixedly connected to one end of the core wire 3, and the connection is completed through the core wire 3 and the lead wire 6.

[0017] A flip-over rubber layer 8 is fixedly connected to the outer side of the middle of the silicone plug 4. The flip-over rubber layer 8 is fitted onto the connection between the water temperature sensor probe body 1 and the silicone plug 4 through the flipping action of the silicone, thereby blocking the water source again. This facilitates use. The flip-over rubber layer 8 covers the outside of the water temperature sensor probe body 1 by flipping. A rubber tube 10 is fixedly connected to one end of the sealing cover 7. The core wire 3 passes through the rubber tube 10 at one end of the sealing cover 7. The core wire 3 expands the rubber tube 10, and the rubber tube 10 is firmly and tightly fitted to the core wire 3, thereby achieving a high-strength waterproof effect. The rubber tube 10 is fitted onto the outside of the core wire 3. Two arc-shaped grooves are opened inside the water temperature sensor probe body 1 near the end of the silicone plug 4. Two rubber rings 5 ​​are fixedly connected to one end of the silicone plug 4. The two rubber rings 5 ​​at one end of the silicone plug 4 can cooperate with the arc-shaped grooves on the inner wall of the water temperature sensor probe body 1 to achieve a plug-in sealing effect. The rubber rings 5 ​​and the arc-shaped grooves are arc-shaped.

[0018] Working principle: In use, one end of the silicone plug 4 is first inserted into the water temperature sensor probe body 1. During the insertion process, the core wire 3 needs to be passed through the through hole 9, and then through the sealing cover 7 again. This ensures that the core wire 3 does not affect the use and achieves a high-strength waterproof effect. One end of the silicone plug 4 is equipped with two rubber rings 5, which can cooperate with the arc-shaped groove on the inner wall of the water temperature sensor probe body 1 to achieve the insertion and sealing effect. After insertion, the core wire 3 passes through the rubber tube 10 at one end of the sealing cover 7. The core wire 3 expands the rubber tube 10, and the rubber tube 10 is firmly and tightly attached to the core wire 3, thereby achieving a high-strength waterproof effect. Then, the core wire 3 is connected to the lead wire 6. Finally, the flipped rubber layer 8 is sleeved on the connection between the water temperature sensor probe body 1 and the silicone plug 4 through the silicone flipping action, which can block the water source again. At this time, it can be used.
