[0002] Currently, commonly used pool thermometers on the market have the following shortcomings:

[0003] 1) The thermometer is not waterproof. After water gets into the product, the display screen fogs up, making it difficult for users to see the displayed temperature, resulting in a poor user experience.

[0004] 2) The temperature sensor cable is usually connected to the host by soldering, which makes the cable easy to break.

[0005] 3) The stainless steel tube of the thermometer base is sealed, which makes the probe temperature response slow and the product has high buoyancy when placed in water, resulting in poor performance. Utility Model Content

[0006] The purpose of this invention is to provide a waterproof swimming pool thermometer to solve the above-mentioned problems.

[0007] To achieve the above objectives, the following technical solution is adopted:

[0033] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Reference Figures 1 to 7 As shown, this utility model provides a waterproof swimming pool thermometer. In one embodiment, it includes...

[0035] A base 1, wherein a stainless steel tube 11 is installed inside the base 1 along its length, and a temperature sensor is arranged inside the stainless steel tube 11.

[0036] Power box 3, which is installed in base 1 and contains a power supply battery 31;

[0037] The faceplate 4 is connected to the top of the base 1, and a PCB board 41 connected to the power supply battery 31 and temperature sensor is installed inside the faceplate 4; a first waterproof ring 42 is also fitted on the outer wall of the faceplate 4, and the bottom of the first waterproof ring 42 contacts the top of the power box 3, and one side of the outer wall of the first waterproof ring 42 contacts the inner wall of the base 1; a display screen 43 connected to the PCB board 41 is also installed on the faceplate 4.

[0038] The screw cap 5 is screwed to the upper outer wall of the base 1 and presses the faceplate 4 tightly onto the base 1.

[0039] Continue to refer to Figures 1 to 7 As shown, in this embodiment, the temperature sensor is directly connected to the PCB board 41 via a cable. In a preferred embodiment, a probe bracket 2 is also installed inside the base 1 below the power supply box 3, and a spring pin 21 is also installed on the probe bracket 2. A copper pillar 32 that contacts and connects to the spring pin 21 is also installed on the power supply box 3. The temperature sensor is connected to the PCB board 41 via the spring pin 21 (the bottom of the spring pin 21 is connected to the temperature sensor) and the copper pillar 32 (the top of the copper pillar 32 is connected to the PCB board 41). Other connection methods can also be used, and there are no restrictions on them. The following explanation uses the connection method of spring pin 21 and copper pillar 32 to illustrate the principle.

[0040] During operation, after the thermometer is placed in the swimming pool, the temperature sensor inside the stainless steel tube 11 detects the liquid temperature and transmits the detected signal to the PCB board 41 via two spring pins 21 (one positive and one negative; the spring pins 21 are glued for fixation and waterproofing after assembly) and two copper pillars 32 (the two copper pillars 32 are injection molded and arranged corresponding to the two spring pins 21). The PCB board 41 processes the signal and then sends the temperature value to the display screen 43 for easy viewing by the user. In this embodiment, the temperature sensor wire is connected by contact between the copper pillars 32 and the spring pins 21, which solves the problem of easy wire breakage caused by using cable connection.

[0041] Meanwhile, the bottom of the base 1 is provided with a first groove 13, and a first through hole is provided in the first groove 13 to penetrate into the base 1; the end of the stainless steel tube 11 with the temperature sensor installed passes through the first through hole and is inserted into the first groove 13; a number of slits 14 penetrating into the first groove 13 are provided at intervals on the outer circumference of the first groove 13. The stainless steel tube 11 is directly injection molded into the base 1 to increase the waterproof level and stability of the base 1. The bottom of the base 1 is provided with a first groove 13, and the outer circumference of the first groove 13 is provided with slits 14, which allows liquid to flow into the groove through the slits 14 and fully contact the stainless steel tube 11, thereby improving the temperature response speed and reducing buoyancy. This reduces the weight of the weight block in the thermometer, thereby improving the product's portability. In a preferred embodiment, there are four sets of slits 14, and their bottoms appear to be in a cross shape.

[0042] In addition, an antenna housing 45 extends upward from the top of the faceplate 4, and a communication antenna 46 connected to the PCB board 41 is arranged inside the antenna housing 45. The temperature value detected by the thermometer can be transmitted to an external device through the communication antenna 46 for user observation, improving convenience.

[0043] In one embodiment, the bottom of the first waterproof ring 42 extends downward with a first extension 421, and the diameter of the first extension 421 is smaller than the diameter of the first waterproof ring 42; the lower outer wall of the first extension 421 extends outward with a first protrusion 422, and the bottom of the first extension 421 also extends downward with a second extension 423, and the diameter of the second extension 423 is smaller than the diameter of the first extension 421; the bottom of the second extension 423 contacts the top of the power box 3, and the top of the power box 3 extends upward with a first protruding rib 33, which abuts against the bottom of the first protrusion 422; the inner wall of the base 1 contacts the outer wall of the first protrusion 422, and the top of the base 1 extends upward with a second protruding rib 12, which abuts against the bottom of the first waterproof ring 42.

[0044] Meanwhile, the power box 3 has a first cavity with an opening at its bottom, and the power supply battery 31 is installed in the first cavity; a battery cover 34 is installed at the bottom opening of the first cavity, and a second waterproof ring 35 that contacts the battery cover 34 is also embedded in the inner wall of the bottom opening of the first cavity.

[0045] In this embodiment, the faceplate 4 and the display screen 43 employ an ultrasonic waterproofing structure (ultrasonic welding achieves a tight connection between the faceplate 4 and the display screen 43, thereby preventing the intrusion of moisture and dust). The battery cover 34 adopts a waterproof ring structure to prevent water from entering the power box 3, which could affect the normal operation of the thermometer. The waterproofing of the faceplate 4 and power box 3 assembly adopts a waterproof ring structure, namely, the first waterproof ring 42 fitted onto the faceplate 4. Figure 5 As shown, a multi-point waterproof design with different surface structures is adopted, which can contact the second protruding rib 12 on the top of the base 1 and the inner side to achieve double waterproofing and better waterproofing effect.

[0046] In one embodiment, the outer wall of the faceplate 4 is further provided with a first mounting step 44, and the bottom of the first mounting step 44 is further provided with a first groove in an annular structure; the first waterproof ring 42 is embedded in the first groove; the outer wall of the probe bracket 2 is provided with a second groove in an annular structure, and a third waterproof ring 22 that contacts the inner wall of the base 1 is also embedded in the second groove. The base 1 and the probe bracket 2 are waterproofed by the third waterproof ring 22 located on the outer wall of the probe bracket 2, which further improves the waterproof performance.

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
