Self priming micro water pump for soap dispenser

Why can micro water pumps be used in smart sensing soap dispensers?

The DC Diaphragm Water Pump compresses and stretches the air inside the pump chamber by reciprocating the diaphragm inside the pump through the circular motion of the motor. This movement creates positive pressure at the drainage outlet, creates a vacuum at the pumping outlet, and thus creates a pressure difference with the external atmospheric pressure. Under the pressure difference, the liquid is sucked into the inlet and then discharged from the outlet, forming a stable flow rate.

In the infrared sensing soap dispenser, the main function of the Mini Water Pump is to extract the soap solution from the storage container and transport it through a pipeline to the soap outlet. When the infrared sensor detects that the user's hand is approaching, it will trigger the operation of the 12V Water Pump to pump out the soap solution. In this way, users can easily obtain soap without directly contacting the soap dispenser.

How can a Micro Water Pump achieve automatic extraction and transportation of soap solution?

1. Induction stage: When the user's hand approaches the infrared sensing soap dispenser, the infrared sensor will detect this action. This sensor can detect human heat or movement very sensitively, triggering the next action.

2. Start the water pump: Once the infrared sensor is triggered, it will send a signal to the self primign micro water pump to start working. This process is automatic and users do not need to manually operate it

3. Soap extraction: When the Mini Liquid Pump starts working, it will generate positive and negative pressure through the internal diaphragm movement. Under negative pressure, the soap liquid is sucked into the inlet of the water pump

4. Delivery of soap solution: Subsequently, under the positive pressure of the micro diaphragm water pump, the already inhaled soap solution is compressed and transported to the soap solution outlet through the outlet. This process is continuous, as long as the water pump remains in operation, the soap will be continuously extracted and transported.

5. Stop working: When the user's hand leaves the sensing range of the infrared sensing soap dispenser, the infrared sensor will stop sending signals to the micro diaphragm water pump, and the water pump will also stop working. In this way, the automatic extraction and transportation of soap liquid have been achieved.

Technical Specification

What are the advantages of a DC Liquid Pump in an infrared sensing soap dispenser?

1. Efficient and energy-saving: During the operation of the Liquid Dispenser Pump, the circular motion of the motor causes the diaphragm inside the pump to move back and forth through a mechanical device, effectively compressing and stretching the air inside the pump chamber. This design allows the water pump to create a vacuum during pumping, creating a pressure difference with the external atmospheric pressure, thereby more efficiently introducing water pressure into the inlet and discharging it from the outlet. This efficient working method helps to reduce energy waste and achieve energy-saving goals.

2. Good stability: During the pumping process, the Portable Electric Liquid Pump continuously sucks in and out water due to the circular motion of the motor, forming a relatively stable flow rate. This stability is crucial for infrared sensing soap dispensers to ensure timely and stable supply of soap when needed.

3. Strong durability: The diaphragm of the Mini DC Liquid Pump is made of soft plastic material, which does not have significant mechanical stress, thus having high durability. In addition, when there is no liquid in the pump, due to the soft nature of the diaphragm, it is not as easily damaged as other types of water pumps. This durability allows the micro diaphragm water pump to maintain good performance even after long-term use in infrared sensing soap dispensers.

4. Wide application range: Micro diaphragm water pumps are suitable for various power supply methods, including DC low voltage and AC power. This makes it widely applicable in various environments and application scenarios. For example, in an infrared soap dispenser, a suitable power supply method can be selected based on actual needs and conditions.

How can micro diaphragm water pumps adapt to conveying different liquid viscosities?

1. Diaphragm design: The core component of a Mini Hydraulic Pump is the diaphragm, which is responsible for forming a seal in the pump chamber and generating pressure changes. The material and thickness of the diaphragm have a significant impact on the delivery capacity of the pump. For high viscosity liquids, it is usually necessary to use thicker diaphragms to increase the durability and sealing of the pump. For low viscosity liquids, thinner diaphragms can be used to reduce pump resistance and improve efficiency.

2. Pump chamber design: The size and shape of the pump chamber can also affect the pump's conveying capacity. For high viscosity liquids, the pump chamber is usually designed to be larger to accommodate more liquid and reduce the flow resistance of the liquid inside the pump. At the same time, the shape of the pump chamber will also be optimized to reduce liquid retention and accumulation.

3. Motor and driving mechanism: The motor and driving mechanism of the miniature hydraulic pump are responsible for driving the diaphragm to move back and forth. For high viscosity liquids, greater driving force is required to overcome the viscous resistance of the liquid. Therefore, motors typically require higher power and are equipped with appropriate reduction mechanisms to provide sufficient driving force.

4. Control system: The control system of the DC electric hydraulic pump can be adjusted according to the viscosity of the liquid and the conveying needs. For example, for high viscosity liquids, the control system can adjust the motor speed and diaphragm motion frequency to optimize the pump's conveying effect. At the same time, the control system can also monitor the working status of the pump and make automatic adjustments or fault alarms as needed.

Why can DSB413-H Mini Diaphragm Pump spray hand sanitizer with foam?

The reason why DSB413-H can spray foam out of hand sanitizer is mainly due to its special foaming device and design. Within this type of device a special bubbler or foam generator is installed in the part. When the hand sanitizer flows through this bubbler, it will pass through a series of physical process converts the liquid into foam.

Specifically, there are some small holes or slender channels inside the bubbler. When hand sanitizer passes through these small holes, due to changes in pressure under the tension of the liquid surface, the hand sanitizer is stretched into slender filaments and quickly breaks to form foam. These foam have larger surface area and softer touch make users feel richer foam when using it, and clean hands more effectively.
