Description

Technical Field

[0001] This utility model relates to the field of water pump technology, and in particular to a split-type water pump with an automatic shut-off function when there is no water. Background Technology

[0002] In daily life and production, split-type electric water pumps are widely used in scenarios such as bottled water supply and water extraction from small storage containers due to their flexible installation and ease of use. However, most mainstream split-type electric water pumps on the market currently have a functional defect: they lack an automatic shut-off mechanism when there is no water.

[0003] However, the operation and control of traditional water pumps are highly dependent on the switching on and off of external water-using equipment. The pump can only be indirectly controlled by opening or closing water terminals such as faucets when there is sufficient water. Once the water in the bucket or storage container is exhausted, the traditional water pump cannot recognize the water shortage state on its own. Even if the water-using equipment is turned off, the water pump will continue to run dry. At this time, if the user forgets to turn off the power or does not replenish the water in time, the water pump will be in a dry-burning state without liquid cooling and lubrication for a long time. This will not only quickly damage the pump body components and shorten the service life of the equipment, but may also cause the insulation layer to burn due to continuous high temperature, leading to serious safety accidents such as fires, posing a great threat to the user's property and personal safety. Therefore, we propose a split-type water pump with a water shortage automatic shutdown function to solve the above problems. Utility Model Content

A one-way valve is provided on the branch pipe, and a pressure switch is connected to the branch pipe. A circuit board for controlling the water pump is installed on one inner wall of the water pump housing. A water shortage indicator light is provided on the top of the water pump housing.

[0021] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0022] This application discloses a split-type water pump with an automatic shut-off function when there is no water.

[0023] Reference Figure 1-2 A split-type water pump with a water shortage automatic shut-off function includes a water pump housing 1, a water pump 2 installed inside the water pump housing 1, a water inlet 3 at the bottom of the water pump housing 1, a branch pipe 31 connected between the water pump 2 and the water inlet 3, and a liquid sensor 301 installed on the branch pipe 31; a water outlet 4 at the bottom of the water pump housing 1, a branch pipe 41 connected between the water pump 2 and the water outlet 4, a one-way valve 401 installed on the branch pipe 41, and a pressure switch 402 connected to the branch pipe 41; a circuit board 5 for controlling the water pump 2 is installed on one inner wall of the water pump housing 1; and a water shortage indicator light 6 is installed on the top of the water pump housing 1.

[0024] In this embodiment, a reset button 7 is provided on one side of the water pump housing 1, and a power plug socket 8 for powering the circuit board 5 and the water pump 2 is provided on one side of the water pump housing 1. The reset button 7 is provided so that the water pump can be quickly restored to normal operation when water is replenished after the water pump stops running due to lack of water. The power plug socket 8 provides a stable power input to the circuit board 5 and the water pump 2 to ensure the normal operation of the equipment.

[0025] In this embodiment, the inlet 3 is connected to a water tank via a pipe fitting, and the outlet 4 is connected to a water-using device via a pipe fitting. This split connection method makes the connection between the pump, the water tank, and the water-using device more flexible and convenient. Multiple pumps 2 are configured and connected in parallel within the housing. The parallel connection of multiple pumps 2 improves pumping efficiency and meets the needs of high-flow-rate pumping.

[0026] In this embodiment, the circuit board 5 includes a circuit board control module, which is connected to a power supply and is also electrically connected to a water shortage indicator light 6. As the control core of the water pump, the circuit board control module can receive signals transmitted by various sensors and switches, and control the water pump 2 and the water shortage indicator light 6 according to a preset program. The power supply provides the circuit board control module with the electrical energy required for its operation, ensuring its stable operation. The water shortage indicator light 6 lights up when the water pump detects insufficient water, providing users with an intuitive status prompt so that users can replenish the water source in a timely manner.

[0027] In this embodiment, the liquid sensor 301 is electrically connected to the circuit board control module, the circuit board control module is electrically connected to the pressure switch 402, and the pressure switch 402 is electrically connected to the water pump 2. The liquid sensor 301 is used to detect whether there is liquid flowing in the first branch pipe 31. When no liquid is detected in the first branch pipe 31, it indicates that the water source has been exhausted, and the liquid sensor 301 transmits a signal to the circuit board control module. The pressure switch 402 is used to detect the liquid pressure in the second branch pipe 41. When the pressure in the second branch pipe 41 reaches a preset value, the pressure switch 402 is activated and transmits a signal to the circuit board control module. The circuit board control module controls the operating status of the water pump 2 according to the received signals from the liquid sensor 301 and the pressure switch 402 to realize the automatic stop function when there is no water.

[0028] In this embodiment, the power supply is also electrically connected to the reset button 7, and the reset button 7 is also electrically connected to the water pump 2. When the water pump stops running due to lack of water, the user replenishes the water supply and presses the reset button 7. The reset button 7 transmits a signal to the power supply and the water pump 2, so that the power supply can re-supply the water pump 2, and the water pump 2 resumes operation, thereby restarting the equipment.

[0029] The working principle of this utility model is as follows: First, an external power source is connected via the power plug socket 8 to power the circuit board 5 and the water pump 2. After the water pump 2 starts, it draws liquid from the bucket through the inlet 3 and branch pipe 31, then delivers it to the water-using equipment through branch pipe 41 and outlet 4. During the pumping process, the liquid sensor 301 on branch pipe 31 continuously monitors whether liquid is flowing through it. When there is sufficient water in the bucket, the liquid sensor 301 detects liquid in branch pipe 31 and transmits a signal to the circuit board control module. The circuit board control module then controls the water pump 2 to continue operating normally, while the water shortage indicator 6 remains off. When the water in the bucket is depleted, no more liquid flows through branch pipe 31. The liquid sensor 301 detects the absence of liquid and transmits this signal to the circuit board control module. Upon receiving the no-liquid signal, the circuit board control module, on the one hand, controls the water pump 2 to stop running to prevent it from running dry and being damaged; on the other hand, it controls the water shortage indicator 6 to illuminate, reminding the user that the water source is depleted and needs to be replenished promptly.

[0030] The one-way valve 401 on branch pipe 2 41 can prevent liquid backflow, ensuring that liquid can only flow from the water pump 2 to the water-using equipment, avoiding the impact on pumping efficiency or damage to the equipment due to liquid backflow. The pressure switch 402 is used to detect the liquid pressure in branch pipe 2 41. When the pressure in branch pipe 2 41 is abnormal, the pressure switch 402 transmits a signal to the circuit board control module. The circuit board control module can control the water pump 2 to stop running according to the preset program, which plays a role in protecting the equipment. When the user replenishes the water source, press the reset button 7 on one side of the water pump housing 1. The reset button 7 transmits a signal to the power supply and the water pump 2. The power supply re-supply the water pump 2, the water pump 2 resumes normal operation, the water shortage indicator 6 goes out, and the equipment continues to pump water.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
