The invention is described in further detail below with reference to the attached drawings and detailed description:
as shown in fig. 3, 4 and 5, the pump body device for dripping pills of the present embodiment comprises a body 110 and a valve rod assembly 120. Specifically:
the body 110 is provided with a liquid passage 111, and a first switch passage 112, a second switch passage 113 and a dosing passage 114 which are substantially vertical and are communicated with the liquid passage 111, respectively. The quantitative passage 114 is located between the first switch passage 112 and the second switch passage 113, and the junction of the first switch passage 112 and the liquid passing passage 111 is located upstream of the junction of the second switch passage 113 and the liquid passing passage 111. In addition, the liquid passage 111 is provided with a liquid inlet 1111 for inputting an external solution, and a liquid outlet 1112 for outputting the solution.
The valve rod assembly 120 includes a first switch rod 121, a second switch rod 122, and a dosing rod 123, where the first switch rod 121 is movably disposed in the first switch channel 112, the second switch rod 122 is movably disposed in the second switch channel 113, and the dosing rod 123 is movably disposed in the dosing channel 114. And the first switch lever 121 is provided with a first liquid passing section 1211 through which the solution passes, and the second switch lever 122 is provided with a second liquid passing section 1221 through which the solution passes.
The working principle is as follows:
As shown in fig. 4, when the pump body device 100 needs to draw a fixed amount of external solution, the first switch lever 121 is controlled to move upward along the first switch channel 112 to position the first liquid passing section 1211 in the liquid passing channel 111, the second switch lever 122 is controlled to move downward along the second switch channel 113 to block the liquid passing channel 111 by the second switch lever 122, and the fixed amount lever 123 is controlled to move upward along the fixed amount channel 114 by a predetermined height. At this time, during the upward movement of the dosing rod 123, a negative pressure is formed inside the liquid passing passage 111, and thus the solution is drawn from the outside through the liquid inlet 1111.
As shown in fig. 5, when the pump body device 100 needs to quantitatively supply liquid outwards, the first switch lever 121 is controlled to move downwards along the first switch channel 112, the first switch lever 121 intercepts the liquid passing channel 111, the second switch lever 122 is controlled to move upwards along the second switch channel 113, the second liquid passing section 1221 is positioned in the liquid passing channel 111, and the quantitative lever 123 is controlled to move downwards along the quantitative channel 114 by a preset height. At this time, the pressure inside the liquid passing passage 111 becomes large during the downward movement of the dosing rod 123, and the solution is discharged to the outside through the liquid outlet 1112.
The quantitative rod 123 is moved by a specific height during both the process of withdrawing the solution from the outside and the process of supplying the solution to the outside. Therefore, the volume of the liquid passing channel 111 enclosed by the first switch lever 121, the second switch lever 122 and the dosing rod 123 is constant in each process of extracting the solution from the outside and supplying the solution to the outside, so that the pump body device 100 can quantitatively supply the solution to the outside each time.
In addition, in the present embodiment, the first switch lever 121, the second switch lever 122, and the dosing lever 123 are respectively in sealing engagement with the first switch passage 112, the second switch passage 113, and the dosing passage 114. In the actual operation, the parts of the first switch lever 121, the second switch lever 122, and the dosing rod 123 that are engaged with the body 110 may be cylindrical bodies made of flexible sealing materials. 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 dosing rod 123. Or annular sealing rings are sleeved on the surfaces of the first switch rod 121, the second switch rod 122 and the quantifying rod 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 switch lever 121, and the second liquid passing section 1221 is provided with an annular groove centered on the central axis of the second switch lever 122. The first liquid passing section 1211 and the second liquid passing section 1221 of the annular groove structure not only can allow the solution to smoothly pass through the first switch lever 121 and the second switch lever 122, but also can facilitate the processing of the annular groove in the actual processing process and control the precision. In another embodiment, the first fluid passage 1211 is a cylinder with a smaller diameter than the first switch channel 112, and the second fluid passage 1221 is a cylinder with a smaller diameter than the second switch channel 113. Still or in another embodiment, both the first and second liquid passing sections 1211, 1221 are provided with a gap 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 penetrating the body 110 from top to bottom, the dosing 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 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 screw fixing hole 115 for fixing the body 110.
In addition, in the pump body device 100 of the present embodiment, when the pump body device is specifically operated, the valve rod assembly 120 is required to be controlled by another driving mechanism. Specifically:
As shown in fig. 1 and 2, in the present embodiment, in the preparation process of the dripping pill, the supply of the liquid medicine and the glue solution is provided by two independent pump body devices 100, and the two pump body devices 100 are driven by one cam device 200, respectively. Wherein each cam gear 200 is provided with 3 cams corresponding to the first switch lever 121, the second switch lever 122 and the dosing lever 123, respectively, by which different movement states of the valve stem assembly 120 are controlled.
Through the above-mentioned scheme of this embodiment, the pump body device 100 of the present disclosure is composed of only one pump body, the first switch lever 121, the second switch lever 122, and the dosing lever 123. Compared with other liquid supply devices for dripping pills in the prior art, the pump body device 100 of the scheme 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 of the preferred embodiments of the present invention and is not intended to limit the present invention, and various modifications and variations may be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
