Description

Technical Field

[0001] This utility model relates to the field of water temperature sensor technology, specifically a novel water temperature sensor. Background Technology

[0002] A water temperature sensor is a device used to measure the temperature of liquids and is widely used in automobiles, home appliances, industrial control, and other fields. It senses changes in the temperature of water or other liquids and converts them into electrical signals for processing or display by the control system. The specific design and operating principle of water temperature sensors may vary in different applications, but most are based on the working principle of thermistors (NTC or PTC) or thermocouples.

[0003] Most existing water temperature sensors require copper components to sense water temperature during use. However, copper components are expensive to manufacture, and existing contact-type water temperature sensors require a large number of sealing rings if they come into direct contact with water, which increases the number of production steps and affects product quality. Therefore, we propose a new type of water temperature sensor. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-5 This utility model provides a technical solution: a novel water temperature sensor, including a connecting pipe 1 connected to an external water pipe and a detection mechanism 4 for detecting water temperature. Both ends of the connecting pipe 1 are fixedly connected to connecting joints 2. Two sets of reinforcing rings 5 ​​are fixedly connected to the outside of the connecting pipe 1. An installation mechanism 3 is provided at the top of the connecting pipe 1. The detection mechanism 4 is snapped into the inside of the installation mechanism 3. The connecting pipe 1 and the installation mechanism 3 are both made of plastic material.

[0020] The connecting pipe 1 and the installation mechanism 3 are both made of plastic, which makes the whole device lightweight. The external water pipe is connected to the connecting pipe 1 through the connecting joint 2. Then, the detection mechanism 4 is installed inside the installation mechanism 3. In this way, the detection mechanism 4 can be used to detect the water temperature delivered by the connecting pipe 1. The detection mechanism 4 installed in this way can complete the water temperature detection without the need for a sealing ring. The multiple sets of reinforcing rings 5 ​​can prevent the connecting pipe 1 from deforming during operation.

[0021] Please see Figure 1 , Figure 2 and Figure 5 The testing mechanism 4 includes a conductive plate auxiliary mounting base 9, a conductive plate body 10, a thermistor 11, and a support frame 12. The conductive plate body 10 is mounted on the conductive plate auxiliary mounting base 9. The conductive plate auxiliary mounting base 9 is made of plastic material. The thermistor 11 is connected to the bottom of the conductive plate body 10. The support frame 12 is fixedly mounted on the bottom of the conductive plate auxiliary mounting base 9.

[0022] The detection mechanism 4 is installed inside the installation mechanism 3. After the connecting pipe 1 is connected to the external water pipe, the thermistor 11 can collect the water temperature change in time and convert the water temperature change into an electrical signal. The conductive plate body 10 is used to transmit the electrical signal. The conductive plate auxiliary mounting base 9 can complete the installation of the conductive plate body 10. The support frame 12 can facilitate the fixed installation of the thermistor 11 and the conductive plate auxiliary mounting base 9.

[0023] Please see Figure 1 , Figure 2 and Figure 4 The installation mechanism 3 includes an installation sleeve 6, an extension tube 7, and a positioning groove 8. The installation sleeve 6 is fixedly installed on one side of the connecting tube 1. One end of the installation sleeve 6 is fixedly connected to the extension tube 7 extending into the interior of the connecting tube 1. A positioning platform 16 that fits against the outer wall of the conductive plate auxiliary mounting seat 9 is provided on one side of the installation sleeve 6. A positioning groove 8 that contacts one end of the conductive plate auxiliary mounting seat 9 is provided inside the installation sleeve 6.

[0024] During the installation of the detection mechanism 4, the positioning platform 16 can be positioned against the outer wall of the conductive plate auxiliary mounting base 9, and the front end of the conductive plate auxiliary mounting base 9 can be positioned in contact with the positioning groove 8. The thermistor 11 can be inserted into the interior of the extension tube 7, and the extension tube 7 is inserted into the interior of the connecting tube 1. This makes it convenient for the thermistor 11 inserted into the extension tube 7 to collect water temperature.

[0025] Please see Figure 1 , Figure 4 and Figure 5 The auxiliary mounting base 9 for the conductive plate is externally fixed with a locking block 14. The inner wall of the mounting sleeve 6 is provided with a locking groove 15 that engages with the locking block 14. When the auxiliary mounting base 9 for the conductive plate is installed, the auxiliary mounting base 9 for the conductive plate, made of plastic material, is elastic, which allows the locking block 14 to retract. Then, when the locking block 14 moves to the position of the locking groove 15, it can pop out, so that the locking block 14 and the locking groove 15 can engage with each other, thus completing the fixation of the auxiliary mounting base 9 for the conductive plate.

[0026] Please see Figure 1 and Figure 2 The top of the connecting pipe 1 and the outside of the mounting sleeve 6 are fixedly connected by multiple sets of reinforcing plates 13. The multiple sets of reinforcing plates 13 can prevent deformation between the connecting pipe 1 and the mounting sleeve 6 during use.

[0027] Please see Figure 1 , Figure 2 and Figure 3 The connecting pipe 1, mounting sleeve 6, extension pipe 7 and reinforcing plate 13 are integrally injection molded. The process is simple, the production cost is low and the service life is long.

[0028] In use, both the connecting pipe 1 and the mounting mechanism 3 are made of plastic, which makes the entire device lightweight. An external water pipe is connected to the connecting pipe 1 via a connecting connector 2. The detection mechanism 4 is then installed inside the mounting mechanism 3, allowing it to detect the water temperature supplied by the connecting pipe 1. This design eliminates the need for sealing rings to detect water temperature. Multiple reinforcing rings 5 ​​prevent deformation of the connecting pipe 1 during operation. After the connecting pipe 1 is connected to the external water pipe, the thermistor 11 promptly detects water temperature changes and converts them into electrical signals. The conductive plate body 10 transmits these signals, and the auxiliary mounting base 9 facilitates the connection of the conductive plate. The main body 10 is installed, and the support frame 12 can be used to fix the thermistor 11 and the conductive plate auxiliary mounting seat 9. When the detection mechanism 4 is installed, the positioning platform 16 can fit against the outer wall of the conductive plate auxiliary mounting seat 9 for positioning, and the front end of the conductive plate auxiliary mounting seat 9 can contact the positioning groove 8 for positioning. The thermistor 11 can be inserted into the interior of the extension tube 7, and the extension tube 7 can be inserted into the interior of the connecting tube 1. This makes it convenient for the thermistor 11 inserted into the extension tube 7 to collect water temperature. When the conductive plate auxiliary mounting seat 9 is installed, because the conductive plate auxiliary mounting seat 9 is made of plastic material, it can cause the locking block 14 to retract. Then, when the locking block 14 moves to the position of the locking groove 15, it can pop out, so that the locking block 14 and the locking groove 15 can be locked together to complete the fixation of the conductive plate auxiliary mounting seat 9.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
