Detailed Description

In order to more clearly illustrate the embodiments of the present invention and the technical solutions in the prior art, the following description will explain specific embodiments of the present invention with reference to the accompanying drawings. It is obvious that the drawings in the following description are only some examples of the invention, and for a person skilled in the art, other drawings and other embodiments can be obtained without inventive effort, and the invention is not limited to this example.

Please refer to fig. 1 to 4. The utility model provides a powder storage, extraction element for the storage and extraction of powder, including box 1 and two supports 2 that are used for supporting box 1, be equipped with compression channel 3 in the box 1 and communicate the thing chamber 4 that puts that compression channel 3 is used for holding powder, put the thing chamber 4 bottom and be equipped with through-hole 5, communicate the clear glass pipe 6 of through-hole 5 and be used for sealing the rubber buffer 7 of clear glass pipe 6; a threaded hole 8 and a screw 9 in threaded connection with the threaded hole 8 are formed in the side wall of the box body 1; be equipped with piston 31 and one end in the compression passageway 3 and connect piston 31, the other end pass through rolling bearing 10 and rotate the connection the piston rod 32 of screw rod 9, be equipped with a plurality of bellyings on the piston 31 and with the sealed journal ring 311 of 3 inner wall looks butt of compression passageway, with through precession screw rod 9 promotes piston 31 removes in compression passageway 3, accomplishes the discharge through the clear glass pipe to powder.

In specific implementation, the rubber plug 7 is plugged at the lower end of the transparent glass tube 6, and the whole storage cavity 4 is in a closed state, so that the medicine powder is hermetically stored; when the medicine powder needs to be extracted, the rubber plug 7 is pulled down, at the moment, because the object placing cavity 4 is in a closed state, the medicine powder rarely or completely cannot fall off from the transparent glass tube 6, the piston 31 can be pushed to move towards the object placing cavity 4 in the compression channel 3 only by screwing the screw rod 9 (namely, the piston moves towards the right direction in the figure 2), the pressure intensity in the object placing cavity 4 is increased, and in order to keep the balance of the internal air pressure and the external air pressure, the medicine powder can be extruded to be discharged through the transparent glass tube 6, so that the medicine extraction is completed; the discharge or descent speed of the powder can also be observed through the transparent glass tube 6; the sealing support ring 311 serves to increase the contact area between the piston 31 and the inner wall of the compression passage 3, and ensure that no gap is formed between the piston 31 and the inner wall of the compression passage 3 when the piston moves.

It should be understood that, since the powder is generally smaller and thinner in volume and is likely to be accumulated at the opening of the transparent glass tube 6 or the through hole 5, in the specific implementation, the diameter of the transparent glass tube 6 and/or the aperture of the through hole 5 can be set within a certain range, so that the powder can not be discharged from the transparent glass tube 6 any more when the screw 9 stops screwing in, and the discharge of the medicine is not affected.

Please refer to fig. 2 again. In this case, the top of the box 1 may further be provided with a feeding hole 11 for communicating the storage cavity 4 with the outside and an end cap 12 for closing the feeding hole 11, so that the produced powder can enter the storage cavity 4 through the feeding hole 11 and the feeding hole 11 is closed by the end cap 12.

In specific implementation, one connection mode of the feeding hole 11 and the end cover 12 is as follows: the inner wall of the feed hole 11 is provided with internal threads, and the outer wall of the end cover 12 is provided with external threads matched with the internal threads of the feed hole 11, namely, the two are connected through threads.

Another embodiment is: the outer wall of the end cover 12 is sleeved with a rubber ring (not shown in the figure) for abutting against the inner wall of the feed hole 11, that is, the end cover 12 is inserted into the feed hole 11, and the feed hole 11 is sealed by abutting the rubber ring against the outer wall of the feed hole 11.

The specific embodiment of the bracket 2 may be: the glass tube support device comprises a base 21 and two vertical plates 22 arranged on the base 21, wherein the vertical plates 22 are fixedly connected with the outer wall of the box body 1 to support the box body 1, and a space is reserved below the box body 1 to accommodate the transparent glass tube 6.

Please refer to fig. 3 again. In this example, the screw rod may further include a disc 13, and one end of the screw rod 9 is fixedly connected with the center of the disc 13; a rocker 131 for rotating the disc 13 in a handheld manner is further arranged on the disc 13 in a protruding manner; put thing chamber 4 bottom and still be equipped with an inclined plane 41, inclined plane 41 keeps away from the one end height that through-hole 5 is higher than being close to the one end of through-hole 5, the benefit of doing so is: the disc 13 can be rotated by holding the rocker 131 to screw in or out the screw 9.

Specific embodiments of the present invention have been described above in detail. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by logical analysis, reasoning or limited experiments in the prior art, which are already known to those skilled in the art, should be within the scope of protection defined by the claims.
