Description

Technical Field

[0001] The utility model relates to the technical field of temperature sensors, in particular to an external temperature sensor for a new-structure pipeline. Background Art

[0002] At present, in order to achieve a constant temperature effect, water heater products on the market are equipped with temperature monitoring temperature sensors on their inlet and outlet pipes. In order to achieve accurate measurement, it is necessary to add a copper joint to the inlet and outlet copper pipes to open the installation hole. Due to the existence of the installation hole, the installation method of the temperature sensor cannot avoid using a combination of threaded tightening and sealing rings or a combination of baffle tightening and sealing rings. Matching tools are also required for installation during operation. The operation method is inefficient in the assembly of the whole machine and after-sales maintenance. At the same time, when operating in the threaded tightening method, workers are prone to twisting and breaking the wires and damaging the sealing layer, which greatly reduces the reliability of the temperature sensor. For the whole machine, once the temperature sensor fails, it will cause the whole machine to malfunction and not work, which also affects the service life of the whole machine. At the same time, the installation method with holes naturally has a leakage point. Loose installation or long-term aging will have the risk of leakage, which will leave hidden dangers for the life of the whole machine and the safety of use. For this reason, a new structure pipeline with an external temperature sensor is proposed to solve the above problems. Utility Model Content

[0020] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0021] In the description of the present invention, unless otherwise specified, "multiple" means two or more; the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] See also Figure 1-5 The utility model discloses an external temperature sensor for a new structure pipeline, comprising an injection molded part 1, an inner cavity of the injection molded part 1 is provided with a detection groove, a copper part 2 is inserted into the bottom of the inner cavity of the detection groove, a temperature measuring groove is provided in the inner cavity of the copper part 2, a thermistor 3 is provided in the inner cavity of the temperature measuring groove, a lead 4 is fixedly connected to the top of the thermistor 3, reserved card slots are provided on both sides of the injection molded part 1, and a pipe clamp spring sheet 5 is clamped in the inner cavity of the reserved card slot.

[0024] The copper part 2 is fixedly connected in the inner cavity of the detection slot by interference riveting, and a reserved height fixing strip 6 is fixedly connected to the bottom of the injection molded part 1;

[0025] By providing the reserved high-setting strip 6, the exposed length of the copper part 2 can be effectively controlled during interference assembly.

[0026] The lead wire 4 is fixed to the top of the thermistor 3 by welding, and the welding position is coated with epoxy resin;

[0027] The copper piece 2 is in the shape of a cylinder with a concave arc at the head, and the copper piece 2 adopts a structural design with a large head and a small tail. The inner cavities of the detection groove and the temperature measuring groove are both provided with fillers 7, and the material of the fillers 7 is epoxy resin;

[0028] By providing a cylindrical copper piece 2 with a concave arc at the head, the copper piece 2 can be made to fit more closely with the circular pipe 8, thereby increasing the contact area, transferring heat more rapidly, and achieving a faster reaction speed. By providing a structural design with a larger head and a smaller tail, the heat absorption area can be increased, the heat dissipation area can be reduced, and the heat absorption and heat gathering effect can be more obvious.

Since the injection molded part 1 is not in contact with the pipe 8 as a whole, the heat of the pipe 8 will be more concentrated at the copper piece 2, and then transferred from the copper piece 2 to the thermistor 3, and the lead 4 transmits the temperature information detected by the thermistor 3 to the outside.
