[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] Refer to Figures 1-5 , a snap-in type installation liquid level switch, including a glue box 3 and a glue box support pillar 4 thereon. A reed switch 12 and a pair of wires 5 are installed inside the glue box support pillar 4. The two ends of the reed switch 12 are respectively connected to the wires 5. The lower end of the glue box support pillar 4 is installed with a flap 1 through a fixing structure. A float 2 is sleeved on the outer wall of the glue box support pillar 4 between the glue box 3 and the flap 1. The bottom of the glue box 3 is provided with a slot with a right-side opening through a slot structure, and a bracket 7 inserted from the right is slidably arranged inside the slot. The horizontal plate at the lower end of the bracket 7 is inserted into the slot, and a U-shaped groove 9 for accommodating the glue box support pillar 4 is opened on the left end surface of the horizontal plate. An activity groove is penetrated through the upper end surface of the glue box 3, and an elastic plate 8 is arranged inside the activity groove. The right end of the elastic plate 8 is fixedly connected to the glue box 3. An elastic buckle 10 is fixedly arranged at the bottom of the left end of the elastic plate 8. A mounting hole 15 matching the elastic buckle 10 is penetrated through the upper end surface of the horizontal plate of the bracket 7, and the elastic buckle 10 is inserted into the mounting hole 15.

[0021] The slot structure includes an L-shaped plate 11. A pair of L-shaped plates 11 located at the front and rear ends are integrally formed at the lower end of the glue box 3, and the cross-sections of the pair of L-shaped plates 11 are symmetrical. The pair of L-shaped plates 11 cooperate with the lower end surface of the glue box 3 to form a slot, and the bracket 7 is inserted into the slot. The top, bottom and side surfaces of the horizontal plate of the bracket 7 are respectively slidably connected to the glue box 3 and the L-shaped plate 11.

[0022] A toggle post 6 is fixedly arranged at the top of the left end of the elastic plate 8.

[0023] The elastic buckle 10 is cylindrical.

[0024] An inclined surface is opened at the lower end of the elastic buckle 10, and the inclined surface is lower on the left and higher on the right.

[0025] The fixing structure includes a card slot 13. A card slot 13 is opened on the outer wall of the lower end of the glue box support pillar 4, and the card slot 13 is annular. A flap 1 is clamped inside the card slot 13.

[0026] The flap 1 is circular and provided with a ninety-degree notch 14.

[0027] Working principle: when the water level rises / falls, the float 2 rises / falls with the liquid. When the distance between the magnet in the float 2 and the reed switch 12 is within the sensing range, the sensor is turned on. Similarly, when it is outside the sensing range, the sensor is disconnected. Sending a signal acts on the controller, thereby achieving the purpose of controlling other components; when installing, insert the horizontal plate of the bracket 7 into the slot, fix the bracket 7 in the up and down front and back directions through the L-shaped plate 11 and the plastic box 3, and fix the bracket 7 in the left and right directions through the elastic buckle 10 inserted into the mounting hole 15 to complete the fixed installation; when the horizontal plate of the bracket 7 is inserted into the slot, it first abuts against the inclined surface with the left lower and the right higher, and the right end is at the same height as the height of the plastic box 3, and in the process of continuing to insert, the elastic buckle 10 is squeezed upward and automatically inserted into the mounting hole 15 when the elastic buckle 10 is aligned with the mounting hole 15. When disassembling, the upper end of the right push-toggle column 6 can tilt and drive the left end of the elastic plate 8 to deform upward and drive the elastic plate 8 to rotate the left end to move the elastic buckle 10 upward and disengage from the mounting hole 15, making disassembly more convenient.

[0028] When installing the liquid level switch, the bracket 7 can be installed by inserting the bracket 7 into the slot at the bottom of the plastic box 3, the shape of which matches the cross plate of the bracket 7. The installation is more convenient and quick. Compared with the general liquid level switch, there is no need to assemble nuts during production and installation, and no need to use glue during installation, which can reduce the production and installation time, improve the production and installation efficiency, reduce product costs, and better meet environmental protection requirements. In addition, when disassembling and replacing, you only need to turn the elastic fixing buckle to take out the liquid level switch, and the disassembly will be more convenient and quick.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
