Description

Technical Field

[0001] This utility model relates to a liquid suction pump device and a liquid dispenser, belonging to the field of liquid dispenser technology. Background Technology

[0002] With the continuous advancement of technology, various daily necessities are increasingly equipped with automation functions to enhance convenience and user experience. Taking cleaning products as an example, several automatic liquid dispensers are now available on the market. These dispensers use electric pumps to automatically extract cleaning solutions such as hand soap and dishwashing liquid from the bottle, replacing the traditional manual pump method. Users only need to touch a switch to dispense the liquid, making operation more convenient and effortless, significantly improving the user experience.

[0003] However, existing automatic liquid dispensing devices still have certain limitations in application scenarios, especially in high-humidity and high-temperature environments such as bathrooms, where applicable products are relatively limited. Because bathroom environments are consistently characterized by high temperature and humidity, high requirements are placed on the waterproof performance of the equipment. The liquid pump, as the core component of the automatic liquid dispensing device, is typically driven by a motor to complete the functions of liquid suction and discharge. However, motors themselves often have weak waterproof performance; without effective protective measures, they are prone to malfunction due to moisture intrusion in humid environments, affecting the overall lifespan and reliability of the machine.

[0004] Therefore, there is an urgent need for a simple, reliable, and low-cost liquid suction pump device to promote the widespread application of automatic liquid dispensers in special environments such as bathrooms. Utility Model Content
