Abstract
Description
Technical Field
[0001] The utility model relates to a water leakage protector and a water purifier. Background Art
[0002] A water purifier, also called a water purifier, is a water treatment device that deeply filters and purifies water according to the requirements of water use. Since the water inlet of the water purifier is connected to the tap water pipe, in order to meet the need to make water at any time, the water inlet is in an open state for a long time, and various pipelines and water-making components are under high pressure, which will cause the risk of leakage. At present, in order to remind users of water purifier leakage in time, existing water purifiers are usually installed with leakage protectors. The principle of the leakage protector is: the two metal guides of the leakage board are connected through the conductivity of water, so that the main control board receives a signal and controls the alarm to alarm. When the leakage protector sounds an alarm, it reminds the user that there is a leakage point. However, these leakage protectors have great defects in their structural design. Often, due to a small amount of liquefied water droplets or water vapor inside the machine, the circuit of the leakage protector is turned on and false alarms are triggered, which brings troubles to users and maintenance manufacturers. Utility Model Content
[0003] The technical problem to be solved by the utility model is to overcome the defect of false alarm of the water leakage protector in the prior art, and to provide a water leakage protector and a water purifier.
[0004] The utility model solves the above technical problems through the following technical solutions:
[0005] A water leakage protector comprises a main control board and a water leakage detection unit, wherein the water leakage detection unit comprises:
[0006] an insulating member having a first side surface and a second side surface opposite to each other;
[0007] A first conductive electrode, mounted on the first side surface and electrically connected to the main control board;
[0008] The second conductive electrode is installed on the second side surface and is electrically connected to the main control board.
[0009] In this solution, the water leakage protector includes a main control board and a water leakage detection unit. The main control board is used to detect the electrical signal of the water leakage detection unit. The water leakage detection unit is used to detect the water leakage point. By setting the first conductive electrode and the second conductive electrode connected to the main control board on the first side and the second side of the insulating member respectively, the first conductive electrode and the second conductive electrode are separated by the insulating member. Even if there are a small amount of water droplets or water vapor, the first conductive electrode and the second conductive electrode will not be connected, thereby avoiding the possibility of false alarm of the water leakage protector and improving the reliability of the water leakage protector. When there is a water leakage point, the first conductive electrode and the second conductive electrode are connected by the leaked water, and then an electrical signal is sent to the main control board. After receiving the electrical signal, the main control board first closes the water inlet solenoid valve and uses a variety of methods to alarm at the same time, such as sending a text message to the operating user, displaying a fault on the working machine, or alarming through an alarm light or an alarm. Preferably, the lower end of the first conductive electrode and the lower end of the second conductive electrode are at the same height position, so that a certain amount of water can simultaneously contact the first conductive electrode and the second conductive electrode and connect the two. If the water only submerges one of the first conductive electrode and the second conductive electrode, the first conductive electrode and the second conductive electrode will not be connected, and leakage will occur, posing a safety hazard.

Even if a small amount of condensed water remains at the bottom, the first conductive electrode and the second conductive electrode will not be connected, thereby preventing false alarms. Preferably, the lower end of the first conductive electrode and the lower end of the second conductive electrode are both set higher than the bottom surface of the insulating member by a preset height. This preset height can be set according to the amount of condensed water in the use environment, for example, the preset height is 2 mm or 2 cm.

The insulating member is installed in the vertical direction, so that the lower end of the first conductive electrode and the lower end of the second conductive electrode can be used to detect the water leakage and accurately detect the water leakage point. The insulating member and the fixing bracket are detachably connected, which is convenient for disassembly and assembly of the insulating member.

The lower end of the vertical plate is provided with an L-shaped support portion for supporting the lower end of the PCB board, and the upper end of the vertical plate is provided with a buckle for buckling the upper end of the PCB board.
[0019] In this solution, the insulating member is set as a PCB board (Printed Circuit Board), and the first conductive electrode and the second conductive electrode can be printed on the PCB board, which is convenient for processing and manufacturing the water leakage detection unit. The fixed bracket is used to fix the insulating member, and is also used to fix the insulating member on the external component. Specifically, the vertical plate is used to fix the insulating member, and the horizontal plate is used to connect with the external component. Furthermore, an L-shaped support portion is provided at the lower end of the vertical plate, and a buckle is provided at the upper end of the vertical plate, so that the PCB board can be firmly fixed and the PCB board can be conveniently disassembled and assembled. During installation, the lower end of the PCB board is placed in the groove of the L-shaped support portion, and then the upper end of the PCB board is pressed, and the PCB board is buckled by the buckle. During disassembly, the buckle is opened and the PCB board can be taken out.
[0020] Preferably, the vertical plate is further provided with a limiting portion, and both sides of the PCB board are provided with the limiting portion for abutting against the two sides of the PCB board.

By setting the first conductive electrode 2 and the second conductive electrode 3 connected to the main control board on the first side 101 and the second side 102 of the insulating member 1 respectively, the first conductive electrode 2 and the second conductive electrode 3 are separated by the insulating member 1, even if there are a small amount of water droplets or water vapor, the first conductive electrode 2 and the second conductive electrode 3 will not be connected, thereby avoiding the possibility of false alarm of the water leakage protector and improving the reliability of the water leakage protector. When there is a water leakage point, the first conductive electrode 2 and the second conductive electrode 3 are connected by the leaked water, and then an electrical signal is sent to the main control board. After receiving the electrical signal, the main control board first closes the water inlet solenoid valve, and at the same time uses a variety of methods to alarm, such as sending a text message to the operating user, displaying a fault on the working machine, or alarming through an alarm light or an alarm.
