Water enters the pump body through the water inlet and is discharged from the outlet. The submersible pump method can directly throw the pump body into the water, and the pump body can be disassembled and cleaned by the water wheel method, but the transmission of the pump body needs to be driven by electricity, so there is a risk of electric leakage, and the power line needs to be led out, and some parts of the water tank need to be sealed The wires cannot be drawn out or are inconvenient to use; even though the submersible pumps that are powered by wireless charging have solved the power supply problem of the pump body and do not require power lines, there are still problems with the sealing of the pump body that cause leakage, and are used for sealed irrigation.

When cleaning, only the rotor 202 needs to be dismantled for cleaning, thereby realizing the invention purpose of convenient cleaning. Further, since the inner concave cavity where the rotor 202 is installed is essentially a sub-cavity of the second cavity 102a, and the two are integrated, it is not necessary to adopt technical means such as sealing or bonding, which can prevent the rotor 202 from being dirty when it rotates.

For example, in a water dispenser, the present application can pump the water in the water tank into the heating container, that is, the liquid outlet pipe 206 communicates with the heating container. As another example of an atomizer, the present application can pump the water in the water tank into the atomization chamber, that is, the liquid outlet pipe 206 communicates with the atomization chamber. The top cover 205 is in the shape of a volute.
如图3所示，所述底座204上形成有与所述内凹腔相适应的外凹腔，所述内凹腔嵌套在所述外凹腔内。具体地，内凹腔和外凹腔均为圆柱形，内凹腔的腔壁伸入外凹腔内实现嵌套。在其他实施方式中，泵壳可以仅包括泵2盖，不设置底座204，将外凹腔等结构直接一体地设置在外壳101上即可。为了保证定子201产生的磁场能够驱动转子202旋转，转子202和内凹腔之间的间隙，内凹腔和外凹腔之间的间隙需要设置适当，过远的距离将导致磁场衰减而无法驱动转子202旋转或者旋转动力不足。所述定子201固接在底座204上，且具有供外 凹腔的壁部穿过的通孔。As shown in FIG. 3 , an outer cavity corresponding to the inner cavity is formed on the base 204 , and the inner cavity is nested in the outer cavity.

In other embodiments, the pump casing may only include the cover of the pump 2 without the base 204 , and it is sufficient to directly and integrally set the outer concave cavity and other structures on the casing 101 . In order to ensure that the magnetic field generated by the stator 201 can drive the rotor 202 to rotate, the gap between the rotor 202 and the inner concave cavity, and the gap between the inner concave cavity and the outer concave cavity need to be set appropriately. Too long distance will cause the magnetic field to attenuate and cannot be driven. The rotor 202 rotates or has insufficient rotational power. The stator 201 is fixed on the base 204, and has a through hole for the wall of the outer cavity to pass through.
如图8所示，所述定子201包括线圈和铁芯，线圈缠绕在铁芯的一端部上，所述铁芯的另一端部向外延伸，并具有用于套接所述外凹腔腔壁的套接孔。也即外凹腔的腔壁直接穿过铁芯上的套接孔。As shown in Figure 8, the stator 201 includes a coil and an iron core, the coil is wound on one end of the iron core, the other end of the iron core extends outwards, and has a cavity for socketing the outer cavity socket holes in the wall. That is, the cavity wall of the outer cavity directly passes through the socket hole on the iron core.
进一步地，所述泵壳上配置有液位检测装置3，以用于检测第二容腔102a中的液位。所述液位检测装置3包括电容极片301，该电容极片301电连接至所述控制电路。在本实施例中，电容极片301位于内壳102的底部下方，但与第二容腔102a隔离，也即不伸入第二容腔102a内，以防止污染液体。当电容极片301检测到其上方没有液体时，其电容值产生变化，与该电容极板连接的控制电路检测到该电容变化后，停止向定子201供电，使得转子202停转不再向外界排出液体。Further, the pump casing is provided with a liquid level detection device 3 for detecting the liquid level in the second cavity 102a. The liquid level detection device 3 includes a capacitive pole piece 301, and the capacitive pole piece 301 is electrically connected to the control circuit. In this embodiment, the capacitive pole piece 301 is located under the bottom of the inner shell 102, but is isolated from the second cavity 102a, that is, does not protrude into the second cavity 102a, so as to prevent liquid from being polluted. When the capacitive plate 301 detects that there is no liquid above it, its capacitance value changes, and after the control circuit connected with the capacitive plate detects the change in capacitance, it stops supplying power to the stator 201, so that the rotor 202 stalls and no longer supplies the liquid to the outside world. Drain the liquid.
本实用新型还提供一种液体供应设备，包括上述液体供应组件。所述液体供应设备为饮水机、加湿器、香薰机、空调扇或空气净化器。除了上述液体供应设备外，本申请的液体供应组件还可以应用在其它需要供应液体的设备中。The utility model also provides a liquid supply device, including the above-mentioned liquid supply assembly. The liquid supply equipment is a water dispenser, a humidifier, an aromatherapy machine, an air conditioner fan or an air purifier. In addition to the above-mentioned liquid supply equipment, the liquid supply assembly of the present application can also be applied to other equipment that needs to supply liquid.
实施例二：Embodiment two:
如图10和11所示，在本实施例中，其基本结构和实施例一相同，二者不同之处在于：在实施一中，动子202配置在定子201的中部，而在本实施例中，动子202配置在定子201的外周。具体地，在外壳101的底部向上凸起形成一个凹字形结构，也即中部形成一个向下的凹腔，凹腔的两侧形成两个凸台，凸台内部围绕腔壁形成有用于安装定子201的空腔，定子202安装在该空腔内。在该凹字形结构的外侧可转动地套接有动子，动子202上的磁铁和凹字形结构内的动子相对应以建立磁场连接。动子202的中部固接一个定位轴，在其它实施方式中也可以是枢转连接。定位轴***在凹字形结构中部的凹腔内以对动子202进行定位，在定子201上产生激励磁场时可以驱动动子202围绕该定位轴的中心轴线进行转动，从而驱动固接在动子202上的旋转叶轮转动实现排水。As shown in Figures 10 and 11, in this embodiment, its basic structure is the same as that of Embodiment 1, the difference between the two is: in Embodiment 1, the mover 202 is arranged in the middle of the stator 201, while in this embodiment , the mover 202 is disposed on the outer periphery of the stator 201. Specifically, the bottom of the housing 101 protrudes upward to form a concave-shaped structure, that is, a downward concave cavity is formed in the middle, and two bosses are formed on both sides of the concave cavity. 201, the stator 202 is installed in the cavity. A mover is rotatably sleeved on the outside of the concave-shaped structure, and the magnet on the mover 202 corresponds to the mover in the concave-shaped structure to establish a magnetic field connection. The middle part of the mover 202 is fixedly connected with a positioning shaft, which may also be pivotally connected in other embodiments. The positioning shaft is inserted into the concave cavity in the middle of the concave-shaped structure to position the mover 202. When the excitation magnetic field is generated on the stator 201, the mover 202 can be driven to rotate around the central axis of the positioning shaft, thereby driving the mover 202 fixed on the The rotary impeller on the 202 rotates to realize drainage.
本实用新型的工作原理如下：The working principle of the utility model is as follows:
定子201通电后，定子201上产生电磁场带动转子202转动，转子202与旋转叶轮连接，当转子202转动时，驱动旋转叶轮也高速旋转，排水腔内的液体随着旋转叶轮一起旋转，在离心力的作用下，液体飞离旋转叶轮向外射出，液体从出液孔进入出液管206，然后从出液管206离开液体供应组件。此时，旋转叶轮中心处由于液体被甩向周围而形成既没有空气又没有液体的真空低压区，第二容腔102a中的液体在大气压的作用下又进入泵壳内，液体就是这样连续不断地从第二容腔102a中被抽吸上来又连续不断地从出液管206流出。After the stator 201 is energized, the electromagnetic field generated on the stator 201 drives the rotor 202 to rotate, and the rotor 202 is connected to the rotating impeller. When the rotor 202 rotates, the rotating impeller is also driven to rotate at a high speed, and the liquid in the drainage chamber rotates with the rotating impeller. Under the action, the liquid flies away from the rotating impeller and shoots out, the liquid enters the liquid outlet pipe 206 from the liquid outlet hole, and then leaves the liquid supply assembly through the liquid outlet pipe 206 . At this time, the center of the rotating impeller forms a vacuum low-pressure area without air or liquid due to the liquid being thrown to the surroundings, and the liquid in the second chamber 102a enters the pump casing under the action of atmospheric pressure, and the liquid is continuous like this It is sucked up from the second chamber 102a and flows out from the outlet pipe 206 continuously.
以上所述，仅为本实用新型的具体实施方式，但本实用新型的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本实用新型揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本实用新型的保护范围之内。因此，本实用新型的保护范围应以权利要求的保护范围为准。The above is only a specific embodiment of the present utility model, but the scope of protection of the present utility model is not limited thereto. Any skilled person familiar with the technical field can easily think of changes within the technical scope disclosed by the utility model Or replacement, all should be covered within the scope of protection of the present utility model. Therefore, the protection scope of the present utility model should be based on the protection scope of the claims.
