Referring to fig. 1-4, the local buried type medicine applying and irrigating device can realize medicine mixing and medicine applying and sprinkling irrigation, the corrugated baffle 12 can be driven to compress by driving the pushing plate 16, so that the medicine liquid in the medicine liquid cavity 13 is pressed into the water liquid cavity 14 to be mixed with the water liquid cavity, and then the medicine applying and sprinkling irrigation is realized by pressing out the spray head 15.
Specifically, a screw rod 17 is rotatably connected in the box body 1 through a sealing bearing, the screw rod 17 is in threaded connection with the pushing plate 16, a servo motor 171 for driving the screw rod 17 to rotate is fixed on the box body 1, an operator drives the screw rod 17 through the servo motor 171, the screw rod 17 can drive the pushing plate 16 to vertically seal and slide, when the pushing plate 16 moves upwards, pressure is applied to the liquid medicine cavity 13 and the water liquid cavity 14 at the same time, liquid medicine in the liquid medicine cavity 13 can only be sprayed into the water liquid cavity 14 through a pressure spraying device, and liquid in the water liquid cavity is sprayed out from the spray head 15 under the action of the pushing plate 16, so that an irrigation function is realized;
the pressure spraying device comprises a telescopic pipe fitting 2 fixed in a partition plate 11, wherein the telescopic pipe fitting 2 comprises a first pipe part 21, a second pipe part 22 and a third pipe part 23, the second pipe part 22 stretches and slides in the first pipe part 21, the third pipe part 23 stretches and slides in the second pipe part 22, the first pipe part 21 is connected in the partition plate 11 in a sealing way and is communicated with a liquid medicine cavity 13, liquid leakage holes 24 are formed in the side walls of the first pipe part 21, the second pipe part 22 and the third pipe part 23, a one-way valve is arranged at each liquid leakage hole 24, the arranged one-way valve can ensure that liquid medicine in the liquid medicine cavity 13 flows into the water liquid cavity 14 in one direction, and the liquid medicine cavity 13 generates negative pressure when a pushing plate 16 descends, but external air and liquid cannot flow back to the liquid medicine cavity 13 due to the action of the one-way valve; therefore, the telescopic pipe fitting 2 can be retracted, when the screw rod 17 drives the pushing plate 16 to ascend, the pressure in the liquid medicine cavity 13 is increased, the telescopic pipe fitting 2 which is originally in a telescopic state is pushed and elongated, the second pipe part 22 is pushed out of the first pipe part 21, the third pipe part 23 is pushed out of the second pipe part 22, and therefore the liquid medicine in the liquid medicine cavity 13 can be sprayed out through the liquid leakage hole 24, and the purpose of medicine mixing is achieved.
Wherein, a plurality of stirring paddles 25 are fixed on the outer part of the third pipe part 23, and the stirring paddles 25 are made of soft materials and can be compressed and deformed; when the third pipe portion 23 rotates, the stirring blade 25 outside the third pipe portion 23 can sufficiently mix the chemical liquid in the water liquid chamber 14, and the rotation thereof is performed by providing a linkage device between the third pipe portion 23 and the screw 17.
The linkage device comprises a first bevel gear 18 fixed on the outside of a screw rod 17, an overhanging plate 31 is fixed in a box body 1, a supporting shaft 32 is connected with the overhanging plate 31 in a horizontal rotation mode, a second bevel gear 33 meshed with the first bevel gear 18 is fixed at the end portion of the supporting shaft 32, a locking structure is arranged between a third pipe portion 23 and the supporting shaft 32, when an operator rotates the screw rod 17, the linkage device can drive the first bevel gear 18 to rotate, the supporting shaft 32 is driven to rotate through meshing of the first bevel gear 18 and the second bevel gear 33, and due to the fact that the locking structure is arranged between the supporting shaft 32 and the third pipe portion 23, when the locking structure enables the supporting shaft 32 to drive the third pipe portion 23 to rotate, the stirring blade 25 can be driven to rotate, and an automatic stirring effect is achieved.
The locking structure comprises a protruding part 41, an embedded part 42 and an embedded groove 43, wherein the protruding part 41 is fixed with the supporting shaft 32, the embedded part 42 is fixed at the end part of the third pipe part 23, the embedded groove 43 is formed in the protruding part 41 and is used for the embedded part 42 to be clamped in, when the third pipe part 23 is pushed to be pulled out of the second pipe part 22, the embedded part 42 at the end part of the embedded part can be inserted into the embedded groove 43 in the protruding part 41 at the end part of the supporting shaft 32, so that the third pipe part 23 is driven to rotate when the supporting shaft 32 rotates, and the stirring effect of the stirring blade 25 is realized; the fitting structure of the embedded groove 43 and the embedded part 42 needs to be non-circular, and may be polygonal or have a corner, if the fitting structure is circular, it is necessary to make the friction force between the embedded part 42 and the embedded groove 43 large enough to rotate the support shaft 32 to drive the third pipe part 23 to rotate, and it is also necessary to make the embedded part 42 conveniently inserted into the embedded groove 43; therefore, the circular connection is relatively difficult, and when the circular connection is polygonal or has an angular, the supporting shaft 32 can have enough acting force to drive the third pipe portion 23 to rotate when rotating; and there is no concern about whether the embedded portion of the third pipe portion 23 would extend into the embedded groove 43, because the embedded portion 42 is inserted into the embedded groove 43 when the third pipe portion 23 extends, the first time embedded portion 42 may not be exactly fitted into the embedded groove 43; however, when the screw 17 rotates, the insert groove 43 also rotates, and when the screw rotates to a proper position, the insert portion 42 of the third pipe portion 23 can extend into the insert groove 43, so that the support shaft 32 drives the third pipe portion 23 to rotate, and the stirring blade 25 can play a role in stirring.
When the medicine application irrigation is completed and the reset is needed, the screw rod 17 rotates reversely, so that the pushing plate 16 can be driven to move downwards to return to the original position, and the water cavity 14 is communicated with the outside because of the relation of the spray head 15, so that negative pressure cannot be generated because of the enlarged space; but the medical fluid chamber 13 is still in a closed state; the liquid medicine is extruded, but air and liquid cannot enter due to the action of the one-way valve, so that negative pressure is generated in the liquid medicine cavity 13; this allows the second tube 22 and the third tube 23 to retract; thus preparing for the next dosing mixing irrigation.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
