The invention is described in further detail below with reference to the following detailed description and accompanying drawings:

referring to fig. 3, 4 and 5, the pump body device for pills according to the present embodiment includes a body 110 and a valve stem assembly 120. Specifically, the method comprises the following steps:

the body 110 is provided with a liquid passing channel 111, and a first switch channel 112, a second switch channel 113 and a quantitative channel 114 which are respectively approximately vertical and communicated with the liquid passing channel 111. The dosing channel 114 is located between the first switching channel 112 and the second switching channel 113; and the junction of the first switching passage 112 and the liquid passing passage 111 is located upstream of the junction of the second switching passage 113 and the liquid passing passage 111. In addition, the liquid passing channel 111 is provided with a liquid inlet 1111 for inputting an external solution and a liquid outlet 1112 for outputting the solution.

The valve stem assembly 120 includes a first switch rod 121, a second switch rod 122 and a quantitative rod 123, the first switch rod 121 is disposed in the first switch channel 112 in a vertically movable manner, the second switch rod 122 is disposed in the second switch channel 113 in a vertically movable manner, and the quantitative rod 123 is disposed in the quantitative channel 114 in a vertically movable manner. The first switch rod 121 is provided with a first liquid passing section 1211 for passing the solution therethrough, and the second switch rod 122 is provided with a second liquid passing section 1221 for passing the solution therethrough.

The specific working principle is as follows:

as shown in fig. 4, when the pump device 100 needs to draw a fixed amount of external solution: controlling the first switch rod 121 to move upwards along the first switch channel 112, so that the first liquid passing section 1211 is located in the liquid passing channel 111; the second switch rod 122 is controlled to move downwards along the second switch channel 113, so that the second switch rod 122 cuts off the liquid passing channel 111; simultaneously the dosing rod 123 is moved upwards along the dosing channel 114 by a preset height. At this time, during the upward movement of the quantitative rod 123, a negative pressure is formed inside the liquid passage 111, so that the solution is drawn from the outside through the liquid inlet 1111.

As shown in fig. 5, when the pump device 100 needs to supply a fixed amount of liquid to the outside: the first switch rod 121 is controlled to move downwards along the first switch channel 112, and the first switch rod 121 cuts off the liquid passing channel 111; the second switch rod 122 is controlled to move upwards along the second switch channel 113, so that the second liquid passing section 1221 is positioned in the liquid passing channel 111; while the metering rod 123 is moved downwardly along the metering channel 114 by a predetermined height. At this time, during the downward movement of the quantitative rod 123, the pressure inside the liquid passing channel 111 will be increased, and the solution will be discharged to the outside through the liquid outlet 1112.

It should be noted that the metering rod 123 moves to a specific height during the process of extracting the solution from the outside and supplying the solution to the outside. Therefore, the volume of the liquid passing channel 111 under the first switch rod 121, the second switch rod 122 and the dosing rod 123 is constant during each volume change of the processes of extracting the solution from the outside and supplying the solution to the outside, thereby ensuring that the pump body device 100 can supply the solution to the outside in a dosing manner.

In addition, in the present embodiment, the first switch rod 121, the second switch rod 122 and the quantitative rod 123 are respectively in sealing fit with the first switch channel 112, the second switch channel 113 and the quantitative channel 114. In practical operation, the portions of the first switch rod 121, the second switch rod 122 and the quantitative rod 123, which are engaged with the body 110, may be columns made of flexible sealing material. Or sealing sleeves made of flexible sealing materials are sleeved on the surfaces of the first switch rod 121, the second switch rod 122 and the quantitative rod 123. Alternatively, annular sealing rings may be fitted to the surfaces of the first and second switch levers 121 and 122 and the metering lever 123.

As shown in fig. 3, in the present embodiment, the first liquid passing section 1211 is provided with an annular groove centered on the central axis of the first switching lever 121, and the second liquid passing section 1221 is provided with an annular groove centered on the central axis of the second switching lever 122. The first liquid passing section 1211 and the second liquid passing section 1221 of the annular groove structure not only allow the solution to smoothly pass through the first switch rod 121 and the second switch rod 122, but also allow the annular groove to be easily processed in an actual processing process, and also allow controller precision to be easily achieved. In another embodiment, the first liquid passing section 1211 is a cylinder with a diameter smaller than that of the first switch channel 112, and the second liquid passing section 1221 is a cylinder with a diameter smaller than that of the second switch channel 113. In yet another embodiment, the first liquid passing section 1211 and the second liquid passing section 1221 are both provided with a notch for the solution to pass through.

As shown in fig. 3, 6 and 7, in the present embodiment, the body 110 is a rectangular geometric body, wherein the first switch channel 112 and the second switch channel 113 are through holes respectively penetrating through the body 110 from top to bottom, the quantitative channel 114 is a blind hole disposed on the body 110 from top to bottom, and the liquid passing channel 111 is a channel disposed on the body 110 substantially horizontally. The liquid inlet 1111 is exposed at the side of the body 110, the liquid outlet 1112 is exposed at the bottom of the body 110, and both the liquid inlet 1111 and the liquid outlet 1112 are provided with connecting threads so as to be connected with a pipeline. In addition, in the present embodiment, the bottom of the body 110 is further provided with a threaded fixing hole 115 for fixing the body 110.

In addition, when the pump body device 100 of the present embodiment is specifically operated, the up-and-down movement of the valve rod assembly 120 needs to be controlled by another driving mechanism. Specifically, the method comprises the following steps:

referring to fig. 1 and 2, in the present embodiment, during the preparation of the dropping pill, the liquid medicine and the glue solution are supplied by two independent pump devices 100, and the two pump devices 100 are driven by a cam device 200. Wherein each cam gear 200 is provided with 3 cams corresponding to the first switch lever 121, the second switch lever 122 and the quantitative lever 123, respectively, by which different motion states of the valve stem assembly 120 are controlled.

Through the above scheme of the present embodiment, the pump device 100 of the present invention is only composed of one pump body, the first switch rod 121, the second switch rod 122 and the quantitative rod 123. Compared with other liquid supply devices for dripping pills in the prior art, the pump body device 100 is simple in structure and can accurately control the liquid amount output by the pump body device 100 every time.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
