[0001] The utility model relates to the technical field of water treatment equipment, and more specifically, to a direct drinking water system with a power failure alarm function. Background Art

[0002] As a new drinking water trend, direct drinking water from pipes has now become popular in every household. Since direct drinking water from pipes is a livelihood project, users are highly dependent on it. If the equipment loses power, the power supply system of the equipment will be paralyzed, which will cause the direct drinking water system to shut down, resulting in water supply interruption. The company will not be notified in time for maintenance, resulting in delayed maintenance response, affecting user water use. Moreover, there are many types of equipment power outages. Some power outages may be caused by serious system failures, such as line short circuits, circuit breakers tripping, equipment terminals falling off, and power supply interruption. It is also possible that the circuit of the direct drinking water system is damaged by external units or individuals, and the lines are maliciously or unintentionally cut off, which will cause the equipment to shut down and affect the normal operation of the equipment. It is necessary to notify the administrator as soon as possible for inspection and maintenance. Utility Model Content

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] like Figure 1 As shown, the utility model provides a direct drinking water system with a power failure alarm function, including a PLC control system 1, an Internet of Things gateway 2, a lithium battery 3, a network cable 4, a relay 5, a connection contact 6, a maintenance button 7, a power supply 8, and an AC contactor 9:

[0018] The PLC control system 1 is connected to the Internet of Things gateway 2 via a network cable 4, the network cable 4 is connected between the PLC control system 1 and the Internet of Things gateway 2, the Internet of Things gateway 2 is connected to a relay 5, a power supply 8 is connected between the relay 5 and the Internet of Things gateway 2, the Internet of Things gateway 2 is connected to a lithium battery 3, a connection contact 6 is connected between the lithium battery 3 and the Internet of Things gateway 2, and an AC contactor 9 is connected to the outside of the PLC control system 1;

[0019] When the power supply system is abnormal, relay 5 loses power. At this time, the normally closed relay 5 is turned on, and the lithium battery 3 supplies power to the IoT gateway 2, thereby sending the power failure of the direct drinking water system to the platform through the IoT gateway 2, and notifying the company's operation and maintenance personnel in time to avoid water outage and large losses, thereby achieving the effect of power outage alarm.

[0020] Wherein, a heat sink 15 is provided on the surface of the lithium battery 3, and the heat sink 15 is a hollow cavity;

[0021] The radiator 15 on the surface of the lithium battery 3 can efficiently dissipate the heat of the lithium battery 3 through the radiator 15, so as to avoid the situation that the temperature of the lithium battery 3 is too high during use, thereby causing the lithium battery 3 to be unable to be used normally. The radiator 15 is a hollow cavity, so that the interior of the radiator 15 can be filled with coolant.

[0022] Among them, a maintenance button 7 is connected between the Internet of Things gateway 2 and the lithium battery 3;

[0023] By setting the maintenance button 7, the maintenance button 7 can be pressed during maintenance, so that the lithium battery 3 will not supply power to the Internet of Things gateway 2 regardless of whether the power is off, so that the Internet of Things gateway 2 will not generate a signal.

[0024] Among them, the outsides of the relay 5 and the AC contactor 9 are connected to L110, L211, and L312;

[0025] The electricity used for the direct drinking water system is provided through L110, L211 and L312, and whether the power is off is detected through relay 5 and AC contactor 9.

[0026] Among them, the rated power of power supply 8 is 24V;

[0027] The rated power of the power supply 8 is 24V, so that the power supply 8 can supply power to the Internet of Things gateway 2, so that the Internet of Things gateway 2 cooperates with the relay 5 and the AC contactor 9 to determine whether the power is off.

[0028] The outsides of the relay 5 and the AC contactor 9 are both connected to a neutral row 13 and a ground row 14;

[0029] Through the zero row 13 and the ground row 14 outside the relay 5 and the AC contactor 9, L110, L211, and L312 can be used normally through the zero row 13 and the ground row 14.

[0030] The working principle and use process of the utility model are as follows: the Internet of Things gateway 2 is connected to the power supply 8, the lithium battery 3 is connected in parallel with the output end of the power supply 8, and then the Internet of Things gateway 2 is powered together. The lithium battery 3 is connected in series with the normally closed contact of the relay 5 and a normally closed button switch. If the system power supply is normal, after the relay 5 is powered on, the normally closed contact of the relay 5 is disconnected. At this time, the lithium battery 3 does not power the Internet of Things gateway 2. If the system power supply is abnormal, the relay 5 loses power. At this time, the normally closed contact is turned on, and the lithium battery 3 powers the Internet of Things gateway 2. The platform can continue to send the power failure of the direct drinking water system, and promptly notify the company's operation and maintenance personnel to perform on-site inspection and processing to avoid water outages and increased losses. Under normal circumstances, the PLC control system 1 will collect whether the system is powered on, and judge through the on-off of the auxiliary contacts of the AC contactor 9. The PLC control system 1 collects the on-off signal of the AC contactor 9, and interacts with the Internet of Things gateway 2 through the network cable 4. The Internet of Things gateway 2 reads the system power on-off signal in the PLC control system 1 and reports it to the platform in real time. However, there may be human operation to cut off the power of the equipment. In order to avoid false alarms of the system, a maintenance button 7 is connected in series with the lithium battery 3. If the equipment needs to be repaired, etc., the maintenance button 7 is pressed first. At this time, regardless of whether the system is powered off, the lithium battery 3 does not participate in the power supply and will not upload data to the company's operation and maintenance platform. After the maintenance is completed, the maintenance button 7 is turned off, and the equipment returns to normal, which will not affect the alarm after subsequent abnormalities.

[0031] The direct drinking water system with power-off alarm function can accurately determine whether the equipment is operating normally and notify the company's management as soon as possible. Problems can be discovered and handled in time to minimize the impact of accidents.

[0032] Furthermore, the heat sink 15 can be used to cool the lithium battery 3 to prevent the lithium battery 3 from being overheated during use.
