Abstract

The invention discloses a transparent window with a reed pipe sampling device, a processing method of the transparent window and a special water meter, and belongs to the technical field of reed pipe water meters. The transparent window mainly comprises a window body, the window body is made of transparent plastics, more than one reed pipe is arranged in the window body, the reed pipes are matched with a magnetic pointer of the water meter, and leads of the reed pipes extend out of the window body. According to the invention, the reed pipe and the lead are directly embedded into the transparent window made of the plastic material through a repeated injection molding process, so that the reed pipe meets the requirements of sealing and pressure resistance required by the use of the water meter, the production cost is reduced, the reed pipe is more convenient to replace, and the intelligent water meter with the reed pipe is easier to popularize and produce in batches. The transparent window is mainly used for the reed pipe water meter.

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.
