Detailed Description

The above-described scheme is further illustrated below with reference to specific examples. It should be understood that these examples are for the purpose of illustration and are not intended to limit the scope of the invention. The conditions used in the examples may be further adjusted according to the conditions of the particular manufacturer, and the conditions not specified are generally the conditions in routine experiments.

In a specific embodiment, a micro filter for traditional Chinese medicine experiments is provided, which comprises a first base 1, wherein a first shell 2 is installed at the top end of the first base 1, the top end of the first shell 2 is of an open structure, and in order to realize the collection of a medicament after filtration, a storage tube 4 is installed inside the first shell 2; in addition, an air suction pipe 2.1 communicating with the inside is provided in the peripheral wall of the first casing 2. The second casing 5 that first casing 2 top seal installation was equipped with to both ends are the opening setting about the second casing 5, and its inside places the filtration lid 6 that can filter the medicament.

Wherein, in order to do benefit to the accurate flow of medicament and advance to accomodate inside 4, be provided with in 6 bottoms of filter lid and accomodate the first water conservancy diversion hole 6.1 that 4 mouths of pipe correspond and set up to in order to filter the medicament, at 6 internally mounted filter screens 6.2 of filter lid.

A third casing 8 capable of containing a medicine therein is hermetically attached to the top end of the second casing 5, and a second guide hole capable of allowing the medicine to flow into the filter cover 6 is provided in the bottom end of the third casing 8.

In addition, a top cover 9 is hermetically mounted at the top end of the third shell 8; the top cover 9 is provided with an inflation tube 10 communicating with the inside of the third casing 8. When the medicament is filtered, the air flow flows from the air charging pipe 10 to the exhaust pipe 2.1, so that the pressure difference is formed between the upper end and the lower end of the filter screen 6.2, and the filtering of the liquid medicament is realized.

Synthesize above-mentioned, when using, in the experimenter will need filterable medicament to inject into third casing 8, on the medicament flowed into filter screen 6.2 of filter cover 6 through second water conservancy diversion hole, at this moment, because filter screen 6.2 mesh is higher, the medicament can be detained here. In order to enable the filter screen 6.2 to generate pressure difference up and down, two ventilation modes can be adopted: one of them, connect negative pressure pump with exhaust tube 2.1 to inside the air current from gas tube 10 access to equipment, produce pressure differential from top to bottom at filter screen 6.2, and then can make the medicament filter speed accelerate, improve filtration efficiency, and the medicament flows into through first water conservancy diversion hole 6.1 after the filtration and accomodates pipe 4 and realize the collection of medicament.

Secondly, connect the positive pressure pump through gas tube 10 to the air current flows out from exhaust tube 2.1, also can make filter screen 6.2 produce the pressure differential from top to bottom, filters the medicament fast.

In addition, in order to improve the convenience of the apparatus, an inflating handle 11 is provided at an end of the inflating tube 10 away from the top cover 9, and an experimenter can pinch the inflating handle 11 to pressurize the inside of the third housing 8, thereby forming air pressure inside the apparatus.

In addition, in order to prevent fine impurities in the air from entering the device through the exhaust tube 2.1 when the device is not used, a plug 2.11 for sealing the end part of the exhaust tube 2.1 is arranged at the end, far away from the first shell 2, of the exhaust tube 2.1.

By integrating the scheme, in order to further improve the flowing speed of the medicament, the vibrator 5.2 capable of vibrating the filter cover 6 is arranged on the peripheral wall of the outer side of the second shell 5, and the medicament residue is loosened and dredged by the vibration generated by the vibrator 5.2, so that the filtering efficiency is improved.

In addition, in order to facilitate the placing of filtering cover 6, the inner wall of second casing 5 is provided with boss 5.1 which can make filtering cover 6 joint inside second casing 5, and in order to facilitate filtering cover 6 to take, handle 7 is installed on the top end of filtering cover 6.

In addition, a second base 3 is attached to the bottom in the first casing 2 to facilitate fixing of the storage pipe 4. The storage tube 4 is mounted on the second base 3.

In order to make the more convenient closure or opening in third casing 8 top, be provided with mounting 8.1 on third casing 8 top, top cap 9 is provided with through-hole 9.1, top cap 9 passes through-hole 9.1 suit mounting 8.1, can make top cap 9 slide along third casing 8 tip, can make when the experimenter need inject into third casing 8 with the medicament, make third casing 8 open or closed through rotatory top cap 9, and then improve experimenter's convenience of use nature. And a clamping plate 8.2 is arranged on the opposite side of the fixing piece 8.1 at the top end of the third shell 8, and the edge of the top cover 9 can enter the bottom of the clamping plate 8.2 to realize sealing clamping by rotating.

With the basic embodiment and the above embodiments, the sealing connection between the third housing 8 and the top cover 9 is not limited to one type, and the third housing 8 and the top cover 9 may be sealed by screwing or snap-fit connected by using the snap assembly 12.

Similarly, for the convenience of sealing installation among the shells, the first shell 2, the second shell 5 and the third shell 8 are all provided with the buckle assembly 12, and the adjacent shells are pulled by the buckle assembly 12 to realize sealing of the joint. Also, a threaded or press-fit connection between the housings may be used. The primary reason for using the snap assembly 12 is that no rotation of the housing is required.

Wherein, buckle subassembly 12 is the buckle structure that present glass sealed bottle lid and body realization sticiss sealing connection's buckle structure or toolbox/box are used for keeping the buckle structure of case/lid lock, and above-mentioned buckle structure includes two parts usually to install respectively on the link and by the link, connect earlier through the two and then the tractive form makes the sealing tightly laminate, also realizes high strength's connection simultaneously.

In light of the foregoing description of the preferred embodiments of the present invention, it is to be understood that various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
