It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, a first embodiment of the present invention provides a water pumping device 10 for connecting with a water tank to deliver liquid in the water tank, which includes a liquid-containing chamber p and a squeezing device 14.
In particular, the cavity p is delimited by a rigid wall and a deformable wall. In some embodiments, the cavity p may be entirely bounded by deformable walls.
Referring to fig. 1-3, a water pumping device 10 includes a flexible pump core 11, an outer bracket 12 and a baffle 13, wherein the outer bracket 12 is disposed on an outer peripheral side of the flexible pump core 11, and the baffle 13 is disposed between the flexible pump core 11 and the outer bracket 12 and extends from one of the flexible pump core 11 and the outer bracket 12 to be positioned on the other. The schematic cross-sectional view of the cavity p is shown in fig. 3, and the flexible pump core 11 is made of a deformable material.
Specifically, referring to fig. 2, 4 and 5, the flexible pump core 11 is annular (as shown in fig. 5), the outer bracket 12 is annular (as shown in fig. 4) with a notch 120, the baffle 13 is fixed on the flexible pump core 11, and an end of the baffle 13 away from the flexible pump core 13 is clamped in the notch 120 of the outer bracket 12. In some embodiments, the baffle 13 may be fixed on the outer bracket 12, and an end of the baffle 13 away from the outer bracket 12 is closely attached to the flexible pump core 11, as long as the baffle 13 is disposed between the flexible pump core 11 and the outer bracket 12, and the baffle 13 separates the first water channel 121 and the second water channel 122.
Specifically, the baffle 13 is made of a deformable material, the thickness of the side, close to the flexible pump core 11, of the baffle 13 is smaller than that of the side, far from the flexible pump core 11, of the baffle 13, and when the squeezing device 14 squeezes the position, corresponding to the baffle 13, of the flexible pump core 11, the side, close to the flexible pump core 11, of the baffle 13 moves towards the side, far from the flexible pump core 11, so that the squeezing device 14 is given a way to enable the squeezing device 14 to continue to move.
Specifically, the cavity p is annular with an opening, the baffle 13 is located at the opening of the cavity p, and the extruding device 14 is an eccentric wheel 141. In some embodiments, the pressing device 14 may be a circular roller or the like, the cavity p may be in other shapes, such as a sector shape or an oval shape with an opening, a straight shape, etc., as long as the opposite ends of the cavity p are respectively communicated with the first water channel 121 and the second water channel 122, and the pressing device 13 periodically presses the deformable material from one end of the cavity p to the other end to pump the first water channel 121 and supply the second water channel 122 with water.
Alternatively, the flexible pump core 11 may be entirely made of a deformable material, and the thickness of the deformable material is changed to allow the flexible pump core 11 to partially support, for example, the upper and lower surfaces of the flexible pump core 11 are thicker to support the flexible pump core 11 to have a certain shape, and the middle portion of the flexible pump core 11 is thinner to be squeezed to generate a certain deformation, and to substantially restore the original shape when the squeezing force is removed. Preferably, the flexible pump core 11 is made of rubber, which not only can generate a certain deformation when being squeezed, but also can enable the cavity p to have good sealing performance, thereby preventing water leakage. In some embodiments, the flexible pump core 11 may also be made of other materials, such as other deformable materials like silicone, as long as the flexible pump core 11 can be squeezed and deformed to some extent, and the cavity p has good sealing performance.
It is understood that the interior of the flexible pump core 11 may be partially or entirely made of a deformable material and may be deformed by being pressed, and it is only necessary that the portion in contact with the pressing device 14 is made of a deformable material and is deformed by being pressed.
Alternatively, the outer bracket 12 may be entirely made of a hard material, may be partly made of a deformable material, or may be entirely made of a deformable material with a small deformation degree, as long as the outer bracket 12 is supported when being sleeved on the outer peripheral side of the flexible pump core 11, and is defined with the flexible pump core 11 to form the cavity p.
With reference to fig. 2 and 4, the first water channel 121 and the second water channel 122 are disposed on the outer frame 12, two opposite ends of the cavity p are respectively connected to the first water channel 121 and the second water channel 122, the first water channel 121 is used for connecting to a water tank, a wall surface of the cavity p is at least partially made of a deformable material, and the pressing device 14 periodically presses the deformable material from one end of the cavity p to the other end of the cavity p to pump water from the first water channel 121 and send water from the second water channel 122.

It can be understood that when the pressing device 14 moves continuously from the state shown in fig. 7, the water inlet chamber p1 generates negative pressure, and the liquid is pumped into the water inlet chamber p1 from the first water channel 121, and at the same time, the water outlet chamber p2 generates positive pressure, and the liquid in the water outlet chamber p2 is pumped out from the second water channel 122, when the pressing device 14 moves to the state shown in fig. 8, the liquid in the water outlet chamber p2 is pumped out, and there is no hose structure between the first water channel 121 and the second water channel 122, because the chamber does not need to be additionally provided with a hose to accommodate the liquid, the number of components is reduced, the overall structure is simplified, and the simplicity of the structure of the water pumping device 10 is improved.
