Description

Water treatment equipment, water leakage alarm device and water leakage detection device thereof, and assembly method and water leakage detection method of water leakage detection device
Technical Field
The invention relates to a detection device, in particular to a water treatment device, a water leakage alarm device, a water leakage detection device, an assembly method of the water leakage detection device and a water leakage detection method.
Background
Water treatment facilities are widely used in daily life and industrial production, and for example, water treatment facilities such as water softeners and water purifiers are expected by consumers to improve quality of domestic water. However, water leakage is a big problem often faced by water treatment equipment during use. Generally, water treatment facilities all have higher requirement to the sealing performance of internals, in case the pipeline appears the gap, or the valve body trouble, or precision between the spare part does not reach standard, and the water treatment facilities all takes place to leak in the use because of appearing the clearance between the spare part of interconnect cooperation etc. problem. Once the water treatment equipment has water leakage problem in the using process and is not found in time, a series of troubles are inevitably brought to users. Firstly, most water treatment equipment can be operated only by being directly communicated with a power supply, and water leakage easily causes short circuit of a circuit, so that the water treatment equipment is damaged, and serious possibility of causing electric shock danger to a user threatens the life safety of the user. Secondly, long-time water leakage not only causes water resource waste, but also can cause serious water accumulation in the use environment of the water treatment equipment to soak other surrounding equipment or furniture, thereby causing economic loss for users.
In order to find out that water leakage occurs in water treatment equipment in time and reduce potential safety hazards, the conventional water treatment equipment detects whether water leakage occurs in the water treatment equipment or not by means of a water leakage alarm. Specifically, the water treatment equipment comprises a water treatment main body and at least one water leakage alarm, wherein the water leakage alarm is arranged on the water treatment main body, wherein the water leakage alarm comprises a water leakage detection device and an alarm device, the water leakage detection device is communicably connected to the alarm device, the water leakage detection device comprises a control circuit board and a pair of probes, the pair of probes is fixed on one side of the control circuit board, the probe is electrically connected with the control circuit board, the control circuit board is provided with mounting holes distributed on two sides, the control circuit board is mounted on the water treatment main body by the mounting holes in a mode that the probe faces towards the inner space of the water treatment main body, so that the probe mounted to the control circuit board is held in the inner space of the water treatment body. Once water leaks from the inside of the water treatment main body, the water passes through the water leakage detection device, the pair of probes are electrically connected, the circuit is communicated, and the alarm device which is communicably connected with the control circuit gives an alarm to remind a user of finding out the water leakage of the water treatment equipment in time, so that the water treatment equipment can be repaired in time to reduce the damage caused by the water leakage of the water treatment equipment. However, the water leakage detection device of the water leakage alarm has many problems in the actual use process.
First, the conventional water leakage detecting device is cumbersome to install and disassemble. In order to detect water leakage from the water treatment apparatus in a timely manner, the control circuit board of the water leakage detection device is generally fixed to a bottom of a housing of the water treatment body by screws, and a water treatment body is mounted to the housing to complete assembly of the water treatment body. In addition, the control circuit board of the existing water leakage detection device is installed at the bottom of the housing in a top-down manner, that is, the control circuit board enters the bottom of the accommodating cavity of the housing through an opening of the accommodating cavity of the housing, so that the installation efficiency is low. In addition, once the water treatment body is detected to leak water by the pair of probes fixed to the control circuit board, the user needs to detach the housing of the water treatment body from the water treatment body, take out the control circuit board fixed to the bottom of the housing, and wipe off the water to remove the alarm of the alarm device connected to the control circuit board. The disassembly and assembly process is complex, and the service time of a user is wasted. Furthermore, the mounting and dismounting operations are difficult for inexperienced users, and the control circuit board and the probe are easily damaged during the mounting and dismounting processes, which increases the use cost and maintenance cost of the water leakage alarm.
Secondly, the volume of the pair of probes is small, the area proportion of the probes to the control circuit board is small, if the water treatment body leaks water, water can easily bypass the probes, so that the circuit of the control circuit board is not conducted, the water leakage detection device cannot detect the water leakage phenomenon to cause the water leakage alarm to be in a virtual shape, and the water leakage phenomenon of the water treatment device cannot be found in time.
In addition, the conventional water leakage detecting device is mounted to the housing in such a manner as to be closely attached to an inner wall of the housing of the water treatment main body, and the probe provided to the control circuit board is mounted to one side of the control circuit board so as to face the inner space of the water treatment main body, that is, the conventional water leakage detecting device can only detect whether or not water leaks inside the water treatment main body, and if water leaks from the water treatment main body of the water treatment main body, but the water flows directly to the outside without passing through the inner space, the water leakage detecting device cannot detect the water leakage of the water treatment apparatus.
Furthermore, once the air in the internal space of the water treatment body is humid, the water drops in the air easily cause the pair of probes directly exposed to the air to be conducted, and further cause the alarm device to give a false alarm, which causes trouble to the user.
