Description

Technical Field

[0001] The invention relates to the field of micro pumps, in particular to a micro pump with multiple liquid outlets for a closed liquid bottle. Background Art

[0002] The micro water pump in the prior art is generally a diaphragm pump; the upper cover is provided with an injection-molded hardware needle for water inlet, the side of the upper cover is also provided with a water outlet penetrating the upper cover, and a concave air separation chamber is provided around the water inlet and the water outlet inside the pump; a partition area is provided between the air separation chamber and the water outlet to form a separate cavity for water inlet and water outlet; however, the micro water pump cannot smoothly extract the liquid in the sealed container with vacuum and there will be a siphon phenomenon after the liquid is discharged.

[0003] In the prior art, there is an anti-siphon micro pump with automatic air replenishment function. Through structural improvement, the air inlet needle and the water outlet needle of the upper cover are connected to the sealed container at the same time, so that the air inlet needle and the water outlet needle interact with each other. In addition, a stop valve and a spring device connected to the inside are added inside the valve plate. The stop valve relies on the resistance of the spring itself, so that the stop valve structure set in the micro pump can stop the siphon phenomenon and circulate the liquid in the vacuum sealed container. However, this air replenishment method relies on the external air pressure as the air replenishment power, and the air replenishment capacity is limited.

[0004] The mop products in the foreign market usually use two outlets when spraying water. This is a rule formed in the foreign market. In order to meet the needs of the foreign market, domestic manufacturers must use more than two outlets. When one outlet of the existing multi-outlet micro pump is blocked, the flow rate decreases, and the flow rate of the other outlet will increase a lot, resulting in uneven liquid discharge.
