BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a medicine dispenser to which powder scattering prevention apparatus is applied, and more particularly, to a medicine dispenser to which powder scattering prevention apparatus is applied to prevent powder from scattering to the outside when powder is poured into a medicine dispenser.

In many cases, a raw material is input to a chemical feeder and a part of the raw material is fed to a process using a feeder. At this time, open the inlet of the medicine dispenser and open the bag containing the powder. At this time, there is a case where the powder is scattered while being scattered and flows back to the entrance of the medicine introducing machine. In particular, if the powder is a dangerous substance, it could be fatal to the operator.

In order to solve such a problem, a dust collector is installed in the medicine dispenser as shown in Fig. However, there is a problem in that the dust collector is not able to instantaneously dispose of the powder that is poured at once, and the maintenance cost is high, for example, the filter of the dust collector is frequently changed due to the scattered powder.

Therefore, it is necessary to develop a powder scattering prevention system that prevents the powder falling into the drug dispenser from being scattered at a time.

The present invention provides a drug dispenser in which a buffer space corresponding to the amount of powder poured into a medicine dispenser is provided so as to prevent powder scattered in the medicine dispenser from being sprayed into the mouth or gap of the medicine dispenser do.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. , Thereby not limiting the spirit and scope of the present invention.

FIG. 3 is a state diagram of a buffer bag of a medicine injector to which a powder spraying prevention device before powder is applied, and FIG. 4 is a cross- FIG. 5 is a state view of a buffer bag of a medicine dispenser to which a powder spraying prevention device is applied after a while. FIG. 5 is a state view of a buffer bag of a medicine injector to which a powder scattering prevention device is applied.

A drug dispenser (100) to which the powder spraying prevention device of the present invention is applied comprises: a medicine dispenser (10) having an inlet part; And a buffer module (30) connected to the medicine injector (10) by a pipe (20), wherein the buffer module (30) comprises: a housing (31) communicating with the outside; And a buffer pocket 32 located inside the housing 31 and spatially connected to the pipe 20.

The medicine dispenser 10 has an inlet 11 formed therein. A bag in which the powder P is stored is placed on the inlet portion 11 and is engaged. Thereafter, when the pouch is opened, the powder P is poured into the medicine dispenser 10 through the inlet part 11. Such powder (P) may be used for industrial use such as activated carbon, lime, and pharmaceuticals.

A pipe 20 is connected to the medicine injector 10. The pipe 20 may be coupled to the medicine injector 10 so as to be inclined upward. The powder P in the pipe 20 is inclined to slip into the medicine injector 10 to be injected.

The buffer module 30 is coupled to the end of the pipe 20. The buffer module 30 is composed of a housing 31 and a buffer pouch 32. The housing 31 is spatially connected to the outside. The inlet of the buffer pocket 32 is connected to the inlet of the pipe 20 connected to the inside of the housing 31. The inner space of the buffer pouch (32) is connected to the inner space of the medicine injector (10) through the pipe (20).

The buffer pouch 32 may be a plastic or fabric material and is of a flexible shape. On the buffer pouch 32, the mass body 41 may be further coupled. A rod 42 can be coupled to the upper portion of the buffer bag 32 and a rod 42 is guided to the housing 31.

The mass body 41 may be any member having a weight. The mass 41 should be such a mass that the buffer bag 32 can swell as shown in FIG. 4 when the powder is poured into the medicine injector 10. If the mass 41 is too heavy, the buffer bag 32 can not expand. The mass body 41 may be made of metal or plastic.

The rod 42 guides the mass body 41 so that it can move up and down. When the rod 42 is not present, the mass 41 coupled to the buffer bag 32 of a flexible material falls on the wall surface of the housing 31. As a result, as shown in FIG. 4, the buffer bag 32 can not be unfolded optimally.

Before the powder P is put into the buffer 30, the buffer pouch 32 maintains the shape as shown in Fig. And is seated on the bottom surface of the housing 31 by the weight of the mass body 41 and the weight of the buffer pouch 32.

4, the powder P scattered with the air inside the medicine injector 10 flows along the pipe 20 along the pipe 20, And enters the inside of the pocket 32. The powder P in the buffer bag 32 sinks after a lapse of time. The settled powder P flows back into the medicine injector 10 along the pipe 20. At this time, the vibration device 40 is installed in the pipe 20 to facilitate the movement of the powder P. When installing the vibrating device 40, a flexible connecting body (such as a rubber or a flexible joint) capable of absorbing vibrations between the pipe and the medicine charging device may be required.

On the other hand, when the inlet 11 of the medicine injector 10 is opened to the outside after a sufficient time, the buffer bag 32 sinks again as shown in FIG. As shown in FIG. 5, when the buffer pouch sinks, the outer diameter of the mass body should be larger than the inner diameter of the pipe so that the mass body does not enter the inside of the pipe.

The buffer pouch 32 of this embodiment does not need to be replaced, except in special cases, and can be used semi-permanently. The buffer pouch 32 may be a completely closed structure or may be a material such as a fabric so that the powder P does not leak to the outside.

The filter of the dust collector has to be replaced, and the motor of the dust collector may not be able to suck all of the powder P instantaneously scattered. On the other hand, the buffer bag 32 of the present embodiment can instantaneously expand and buffer the powder P and air scattered in the medicine injector 10. The buffer bag 32 of this embodiment has an advantage that it can be used repeatedly with no force.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Modifications and additions by those skilled in the art to an equivalent range based on the embodiments will also fall within the scope of the present invention.
