Description of the embodiments

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

Examples

Referring to fig. 1-3, the present utility model provides a technical solution: the utility model provides a water level switch communication valve, including valve casing 1, the internally mounted of valve casing 1 has case 3, installs hall subassembly 2 on the valve casing 1, and case sealing head 5 is installed to the front end of case 3, has seted up through-hole 4 on the case 3, and link crank 6 is installed to the bottom of valve casing 1, and link crank 6's one end is located the inside of through-hole 4, and link joint 7 is installed to the other end, and connecting rod 8 is installed to link joint 7's the other end, installs floater 9 on the connecting rod 8.

As shown in fig. 2 and 3: the hall assembly 2 comprises an integrated circuit board 20, the integrated circuit board 20 is mounted on the top of the valve housing 1, and an electric shell 21 is further mounted on the top of the valve housing 1; with the above arrangement, the electric housing 21 can protect the integrated circuit board 20.

As shown in fig. 2 and 3: a hall switch plate 22 is installed at one side of the electric housing 21; with the above arrangement, the hall switch plate 22 can sense the position of the magnet 23.

As shown in fig. 3: the hall switch plate 22 is electrically connected to the integrated circuit board 20.

As shown in fig. 2: the inside of the electric housing 21 is sealed with epoxy resin glue; through the arrangement, the sealing effect is achieved.

As shown in fig. 2 and 3: the Hall assembly 2 further comprises a connecting plate 24, the bottom of the connecting plate 24 is arranged at the tail part of the valve core 3, and the top of the connecting plate 24 is provided with a magnet 23; with the above arrangement, the signal is turned on and off by the position of the induction magnet 23.
