Description

一种用于密闭液瓶的多出液口微型泵A multi-outlet micropump for closed liquid bottle 技术领域technical field
本发明涉及微型泵领域，具体涉及用于密闭液瓶的多出液口微型泵。The invention relates to the field of micro-pumps, in particular to a multi-outlet micro-pump used for closed liquid bottles.
背景技术Background technique
现有技术中的微型水泵一般为隔膜泵；在上盖带有已注塑五金针用于进水使用的进水针，在上盖侧面还设有贯穿所述上盖的出水口，在泵内上面围绕进水口和出水口设有凹陷的分气室；在分气室与出水口之间设有隔断区隔开，用于进水与出水形成单独的腔体；但该微型水泵不能将带有真空的密封容器中的液体顺利抽出及在出液后会有虹吸的现象。The miniature water pump in the prior art is generally a diaphragm pump; the upper cover is provided with a water inlet needle that has been injection-molded with a metal needle for water inlet, and a water outlet passing through the upper cover is also provided on the side of the upper cover. There is a concave air dividing chamber around the water inlet and water outlet; there is a partition between the air dividing chamber and the water outlet, which is used to form a separate cavity for the water inlet and the water outlet; The liquid in the vacuum sealed container can be drawn out smoothly and there will be a siphon phenomenon after the liquid is discharged.
现有技术中存在一种防虹吸带自动补气功能微型泵，通过结构的改进，使上盖的进气针和出水针同时连接密封的容器，以使进气针和出水针相互作用。且在阀板的内部增加设有与内部连通的止流阀、弹簧装置，止流阀依托弹簧的自身阻力，使微型水泵设置的止流阀结构能将虹吸现象得到止制且能将带有真空密封容器中的液体循环抽出，但是这种补气方式依靠的是外界气压为补气动力，补气能力有限。In the prior art, there is a micro-pump with an anti-siphon function of automatic air supply. Through the improvement of the structure, 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. And the inside of the valve plate is provided with a stop valve and a spring device that communicate with the inside. The stop valve relies on the resistance of the spring, so that the stop valve structure set by the micro water pump can stop the siphon phenomenon and can reduce the siphon phenomenon. The liquid in the vacuum-sealed container is pumped out circularly, but this method of supplying gas relies on the external air pressure as the power for supplying gas, and the supplying capacity is limited.
国外市场的地拖产品，喷水时多采用两个出液口，这是国外市场形成的定例，国内厂家为了满足国外市场的需求，必须采用两个以上的出液口。现有的多出液口微型泵的一个出液口堵塞后，流量减少，另一个出液口的流量就会增大很多，出液不均衡。Floor mop products in foreign markets use two more liquid outlets when spraying water. This is a rule formed by foreign markets. In order to meet the needs of foreign markets, domestic manufacturers must use more than two liquid outlets. When one liquid outlet of the existing multi-outlet micropump is blocked, the flow rate is reduced, and the flow rate of the other liquid outlet is greatly increased, resulting in unbalanced liquid output.

Usually, in the application scenario of this kind of pump, the liquid bottle is on the top, and the liquid in the liquid bottle is relatively dense.

The one-way valve can provide a stronger stop flow effect and effectively prevent siphon.
与现有技术相比，本发明具有的有益效果为：多个出液口的供液相对独立，即使发生堵塞，隔膜的变形由电机带动，受堵塞的影响较小，未被堵塞的出液口的流量不会增大；被堵塞的出液口处流量变小但压力增大，较大压力的液体有可能将堵塞冲开，从而实现均衡地向多个出液口供液。利用泵自身的结构进行主动补气，补气同输送液体几乎是同步进行的，可以持续的向液瓶内补充气体，保证液体的稳定输送，尤其是可以稳定地从真空瓶内连续地抽出液体。Compared with the prior art, the present invention has the beneficial effects as follows: the liquid supply of the plurality of liquid outlets is relatively independent, and even if blockage occurs, the deformation of the diaphragm is driven by the motor, which is less affected by the blockage, and the unblocked liquid is discharged. The flow rate of the outlet will not increase; the flow rate at the blocked liquid outlet becomes smaller but the pressure increases, and the liquid with higher pressure may flush out the blockage, so as to achieve a balanced supply of liquid to multiple liquid outlets. The structure of the pump is used for active air supply. The air supply is almost synchronous with the liquid delivery. It can continuously supply gas to the liquid bottle to ensure the stable delivery of the liquid, especially the continuous extraction of the liquid from the vacuum bottle. .
尤其适用于多出液口的地拖产品均衡连续出液，在一定程度上防止出液口堵塞。It is especially suitable for mopping products with multiple liquid outlets in a balanced and continuous manner, preventing the liquid outlet from being blocked to a certain extent.
