[0016] In the description of the utility model, it should be explained that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected;It can be mechanically connected, or it can be electrically connected;It can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the communication between two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0017] The utility model discloses further illustrate below combining with the drawing.

[0018] Please combine with the reference Figs. 1-2 The utility model discloses a filter device for pharmacy medicine, which comprises an outer barrel 1, an inner barrel 3 sleeved in the inner barrel 1, a supporting ring 2 fixedly connected to the inner wall of the outer barrel 1, the inner barrel 3 being arranged on the supporting ring 2, a filter dish 4 detachably connected to the top of the outer barrel 1 and directly above the inner barrel 3, a plurality of connecting holes 9 being formed on one side of the upper end of the inner barrel 3, an air extraction hole 10 being formed on one side of the outer barrel 1, and a pressure relief hole 11 being formed on the side of the outer barrel 1 away from the air extraction hole 10.

[0019] A plurality of filter holes 5 are formed at equal intervals on the bottom of the filter dish 4, a flow guide ring 8 is fixedly connected to the inner wall of the inner barrel 3 and above the connecting holes 9, the filter holes 5 are opposite to the flow guide ring 8, the flow guide ring 8 is annular and triangular in cross section, the filtering speed is slow in the initial and later stages of filtration, most of the filtrate flows down along the inner wall, and the flow guide ring 8 guides the filtrate to avoid being sucked out from the connecting holes 9, the outer wall of the filter dish 4 is fixedly connected to a connecting ring 6, a plurality of pull buckles 7 are connected at equal intervals between the outer wall of the connecting ring 6 and the outer wall of the outer barrel 1, the outer barrel 1 is in a relatively sealed state by the tension of the pull buckles 7, air can only enter through the filter holes 5 and then flow out through the connecting holes 9 and the air extraction hole 10, the pressure relief hole 11 is located at one end of the inner barrel 1 and is provided with a movable sealing ball 14, the sealing ball 14 is sealingly connected to the pressure relief hole 11, the inner barrel 1 is fixedly connected to a mounting ring 12, one end of the mounting ring 12 close to the sealing ball 14 is fixedly connected to a spring 13, the other end of the spring 13 away from the mounting ring 12 is fixedly connected to the sealing ball 14, as the filtration proceeds, the solids at the bottom of the filter dish 4 increase, causing the filtrate to enter the inner barrel 1, resulting in a rapid decrease in the air pressure in the inner barrel 1, if the filtration continues, there is a risk of bottle explosion, by the arrangement of the sealing ball 14, when the air pressure in the inner barrel 1 is too low, the external air pressure drives the sealing ball 14 to move, temporarily opening the pressure relief hole 11, air enters the outer barrel 1 through the pressure relief hole 11, avoiding the equipment from exploding due to the negative pressure.

[0020] Specifically, the utility model uses, inner bucket 3 is placed on the support ring 2 in the inside of outer bucket 1, then filter dish 4 is placed at the top of outer bucket 1, through the pull of pull buckle 7, make filter dish 4, inner bucket 3 and outer bucket 1 form a relative whole, can avoid multiple vessels to produce the collision in the use process, the filter paper is laid on the bottom of filter dish 4 and covers all filter hole 5, opens the air pump, and the air in the inside of outer bucket 1 is separated, makes the filter paper adsorption at the bottom of filter dish 4, pours the filtrate that needs to filter into filter dish 4, the filtrate of external pressure greater flows to the inner pressure smaller outer bucket 1, realizes the purpose of filtering, and the granular medicine remains on the filter paper, and the solution of making the filtrate flows into inner bucket 3, along with the increase of the filtration time, the medicine on the filter paper is more and more, and the solution becomes difficult after the filter paper is blocked, and the air pressure in the inside of outer bucket 1 is still reduced, at this moment, the air pressure in the inside of outer bucket 1 is much smaller than the external air pressure, when the inner and outer pressure difference of outer bucket 1 is greater than the pull of spring 13, sealing ball 14 moves, and the inside and outside of outer bucket 1 are communicated through pressure relief hole 11, avoid that the pressure difference is too large, improve the security.

[0021] The above is only the preferred embodiment of the utility model, and it should be pointed out that, for ordinary skilled person in the art, without departing from the principle of the utility model, a number of improvements and refinements can be made, and these improvements and refinements should be considered as the protection scope of the utility model.
