Abstract
Description
technical field
[0001] The invention belongs to the technical field of reed switch water meters, and in particular relates to a transparent window with a reed switch sampling device, a processing method thereof and a special water meter. Background technique
[0002] With the continuous improvement of people's living standards, smart water meters gradually replace ordinary water meters and enter people's daily lives. Compared with ordinary water meters, smart water meters are more convenient for counting and data post-processing. Commonly used sensors for existing smart water meters include photoelectric sampling devices, Hall elements, and reed switches. Among them, reed switches are the most widely used as passive device sensors. They have low power consumption and long service life. The tube is used in conjunction with a pointer with a magnet, and the reed switch is used as a magnetic switch. With the rotation of the pointer, the reed switch is closed to obtain the corres...
Examples
Embodiment 1
[0027] Embodiment 1: a transparent window with a reed switch sampling device, including a window body 1, the window body 1 is made of transparent plastic, and the inside of the window body 1 is provided with one or more reed switches 2 through an injection molding process. The reed switch 2 cooperates with the magnetic pointer 4 , and the lead wire 3 of the reed switch 2 extends out of the window body 1 .
[0028] Such as figure 1 with figure 2 As shown, during manufacture, the shape of the window body 1 is not required. The window body 1 can be regular or irregular with bosses. Parallel to magnetic pointer 4.
[0029] Such as image 3 As shown, the special water meter with the transparent window of the reed switch sampling device includes a water meter body 6, a dial 5 is arranged in the water meter body 6, a magnetic pointer 4 is arranged on the dial 5, and a magnet 7 is arranged in the magnetic pointer 4; the water meter body 6 The above-mentioned transparent window wi...
Embodiment 2
[0038] Embodiment 2: The injection molding shape and size of the reed switch 2 in step 3 correspond to the installation groove 9, and a small amount of injected reed switch 2 in step 3 is assembled into the installation groove 9, and the two are processed into a A whole; others are identical with embodiment one.
[0039] The present invention processes the reed switch 2 and the window body 1 step by step, which can effectively avoid damage to the reed switch 2 by direct injection molding, improves the qualified rate of products, and facilitates batch processing.
