Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in fig. 1 to 3, the present invention includes a gun-shaped housing 1; a cavity 2 is arranged at a handle 5 of the shell 1, a piston plate 3 which can move left and right and reset right is arranged in the cavity 2, a piston rod 4 arranged outside the shell 1 is connected to the piston plate 3, and the shell 1 is hinged with the handle 5 which can swing left and right; a pesticide spraying pipe 6 is inserted in the shell 1; a medicament bottle 7 communicated with the medicament spraying pipe 6 is arranged at the upper end of the shell 1, a rotatable disc 8 is arranged at the joint of the medicament bottle 7 and the medicament spraying pipe 6, and a plurality of grooves 9 are uniformly distributed on the circumference of the disc 8; the chamber 2 is communicated with a hose 10 arranged in the pesticide spraying pipe 6; the handle 5 moves leftwards to extrude the piston plate 3 leftwards and drive the disc 8 to rotate, and after the disc 8 rotates, the medicament can fall into the medicament spraying pipe 6.

In order to realize the installation of the handle 5, the middle part of the handle 5 is hinged on the shell 1.

In order to realize that the disc 8 rotates after the lower end of the handle 5 swings leftwards, a rotating shaft 11 in the front-back direction penetrates through the medicament bottle 7, and the disc 8 is fixedly sleeved on the rotating shaft 11 positioned in the medicament bottle 7; a gear 13 is arranged at the front end and the rear end of the rotating shaft 11 through a one-way clutch 12, two racks 14 which are respectively meshed with the gear 13 are arranged on the shell 1, a vertical through groove 15 is formed in the upper end of the handle 5, and a bulge 16 which is arranged in the through groove 15 is arranged on the rack 14; a compression spring 17 which can lead the rack 14 to reset leftwards is sleeved on the rack 14.

In order to realize the medicine adding of the medicine bottle 7, the upper end of the medicine bottle 7 is provided with a bottle stopper 18.

In order to realize that the extrusion of the piston plate 3 can discharge the air in the chamber 2 through the hose 10, a one-way air inlet valve is arranged at the lower left corner of the chamber 2; the hose 10 is provided with a one-way air outlet valve.

In order to facilitate the resetting of the piston plate 3, the piston rod 4 is sleeved with a spring which enables the piston rod 4 to reset rightwards.

The utility model discloses during the use, at first open bottle plug 18, add the powder inside medicament bottle 7 to cover bottle plug 18, because the lower extreme of medicament bottle 7 is equipped with can the pivoted disc 8 this moment, when disc 8 does not rotate, the powder can't flow in the medicament bottle 7 from.

When the medicine feeding operation is needed, the shell 1 is held by hand, and the medicine spraying pipe 6 is sprayed to the affected part in the oral cavity; then, the handle 5 is pressed, and when the handle 5 is pressed, the air in the hose 10 can be blown out stably by slowly pressing at a constant speed; preventing the powder medicine from being blown away after the flow rate is too high.

The left end and the right end of the rack 14 are installed through the fixing blocks, the rack 14 penetrates through the left fixing block and the right fixing block, and therefore guiding and installation of the rack 14 are achieved, when the lower end of the handle 5 swings leftwards, the upper end of the handle 5 swings rightwards, at the moment, the upper end of the handle 5 is provided with the vertical through groove 15, the rack 14 is provided with the protrusion 16 arranged in the through groove 15, the rack 14 is driven to move rightwards, at the moment, the rack 14 drives the gear 13 to rotate anticlockwise, and after the gear 13 rotates anticlockwise, the one-way clutch 12 drives the rotating shaft 11 and the disc 8 located on the rotating shaft 11 to rotate; after the disk 8 rotates, the groove 9 originally arranged inside the medicine bottle 7 on the disk 8 rotates to the lower end of the medicine bottle 7, namely, the powder medicine falls into the medicine spraying pipe 6; at this time, the air flow in the spraying tube 6 is just blown from left to right, so that the powder medicine can be blown to be sprayed out from the right end of the spraying tube 6 and directly cover the affected part in the oral cavity.

When the handle 5 moves leftwards, the handle 5 is loosened, and the handle 5 is reset rightwards; the power of the handle 5 towards the right is mainly provided by a rack 14, the rack 14 can reset towards the left under the action of a pressure spring 17 sleeved on the rack 14, and then the upper end of the handle 5 is driven to swing towards the left, namely the lower end of the handle 5 can reset towards the right; when the rack 14 is reset to the left, the gear 13 rotates clockwise, and the one-way clutch 12 cannot drive the rotating shaft 11 to rotate, i.e. the disk 8 does not rotate, and the powder cannot fall off. At the same time, the piston plate 3 will be reset to the right under the action of the spring sleeved on the piston rod 4, at this time, the hose 10 is not spraying gas, and the chamber 2 will suck gas from the one-way air inlet valve. The whole device is restored to the initial state; then the pesticide can be sprayed repeatedly according to the requirement, and the dosage can meet the requirement.

This device is at first through setting up rifle shape casing 1, the one-hand operation of being convenient for that can be great only needs handheld casing 1 to press handle 5, alright in order to accomplish the process of adding medicine to, the spray tube 6 of 1 right-hand members of casing simultaneously can conveniently enter into the inside in oral cavity, makes the medicine can spout any disease position.

The device realizes a plurality of functions by pressing the handle 5; on the one hand, the rotation of the disc 8 is realized, the reciprocating motion of the handle 5 is changed into the rotation of the disc 8 through a simple motion traditional mechanism, the groove 9 on the disc 8 is utilized again, the dropping of powder medicines is realized, and the quantity and the size of the groove 9 can directly determine the medicine feeding quantity at each time. On the other hand, the gas is discharged by pressing the handle 5, so that the gas in the spray pipe 6 is sprayed out from left to right through the spray pipe 6, and the powder medicine is just sprayed out; the two supplement each other.

In the resetting process of the device, the disc 8 is prevented from rotating through the one-way clutch 12, so that the medicament can not fall off in the resetting process of the device, and the accuracy and the saving of the medicament are ensured.

The utility model discloses convenient operation, the structure is ingenious, low cost, and it is convenient to make, and is safe effective, has improved the convenient of powder medicine application greatly, has ensured that the position of using medicine is accurate, and the dose is accurate.
