Description

Technical Field

[0001] The utility model belongs to the field of accessories for daily necessities, and specifically relates to a water temperature detection and display device with replaceable batteries. Background Art

[0002] At present, some thermos cups and bathtubs on the market have water temperature detection and display functions, which can intuitively display the water temperature. However, there are deficiencies in battery replacement. In order to ensure the appearance of the product and prevent water ingress, the battery and circuit board are generally sealed by direct glue filling after installation. The temperature display function has a lifespan of only 3-6 months. After the battery is exhausted, the battery cannot be replaced and the temperature cannot be displayed. Utility Model Content

[0003] The utility model provides a water temperature detection and display device with replaceable batteries to solve the technical problems existing in the technical field.

[0004] The utility model provides a water temperature detection and display device with replaceable batteries to solve the above technical problems, comprising a base and an upper cover, wherein a water temperature detection circuit board is arranged on the base, and the upper cover is arranged on the base by ultrasonic welding. A battery sliding window is opened on the upper cover, and a push-pull button battery assembly is arranged at the position of the battery sliding window, a button battery is arranged on the push-pull button battery assembly, and a push-pull button battery sealing ring is also sleeved on the push-pull button battery assembly. After the push-pull button battery assembly is pushed into the battery sliding window, the button battery provides power for the water temperature detection circuit board, and the push-pull button battery sealing ring is sealed and connected to the battery sliding window.

[0005] Furthermore, the water temperature detection circuit board is provided with a detection cable connected to the water temperature sensor and a water temperature display screen. The detection cable passes through the bottom of the base and is provided with a wiring sealing ring at the passing position. The upper cover is provided with an observation window for observing the water temperature information, and the observation window is made of light-transmitting material.

[0006] Furthermore, a button battery blocking piece is provided at the bottom of the water temperature detection circuit board, and an elastic battery clamping piece is provided on the button battery blocking piece. After the button battery assembly is pushed in from the battery sliding window, the button battery is stuck on the button battery blocking piece and is clamped by the elastic battery clamping piece.

[0007] Furthermore, the base is also provided with a snap-in ear, which is snap-connected with the component to be tested via the snap-in ear.

[0008] Furthermore, the base and the upper cover are in the shape of a square structure or a circular structure.

[0009] Compared with the prior art, the technical solution solves the problem that the button batteries of water temperature detection and display devices such as traditional thermos cups and bathtubs cannot be replaced, resulting in the display function having only 3-6 months, by using a push-pull button battery assembly, which facilitates the replacement of button batteries. At the same time, a push-pull button battery sealing ring is provided on the push-pull button battery assembly to ensure sealing, thereby solving the problem that the circuit assembly cannot be disassembled and the battery cannot be replaced after glue filling in the traditional glue filling process, and the circuit module with problems after glue filling can only be scrapped as a whole. At the same time, if there is a problem with the push-pull battery circuit, it can be repaired to reduce the defective rate and reduce production costs. BRIEF DESCRIPTION OF THE DRAWINGS
