[0003] The veterinary drencher is a medical device commonly used by veterinarians. It is usually carried by veterinarians to drench animals. However, since veterinarians have little contact time with horses that need treatment and do not understand the habits of horses, it is easy for horses to become stressed and refuse to cooperate with treatment. At the same time, in many emergencies when horses are injured or have problems outside, there is no time to mobilize more manpower and large equipment to control and treat the horses. Therefore, there is an urgent need to design a purely mechanical product that can reduce the stress of horses while allowing veterinarians to quickly complete the task of drenching horses by one person to ensure that the best treatment time is not missed.

In order to prevent the liquid in the cartridge 22 from leaking through the leakage holes 224, two sets of sealing blocks 231 arranged in parallel are fixedly installed in the bottom wall of the magnetic ring 23, and both ends of the sealing blocks 231 slide through the fixed frame 21. Two process holes 230 are symmetrically arranged on the side wall below the magnetic ring 23, and the process holes 230 penetrate the corresponding sealing blocks 231. A liquid separation head 232 connected to the process hole 230 is fixedly installed on the lower end surface of the magnetic ring 23, and the lower end of the liquid separation head 232 is connected to the hose 3.

[0034] When the magnetic piston 26 moves in the process of the cartridge 22, the injection hole 262 inside it is connected with the leakage hole 224, and at this time, the lower end of the leakage hole 224 can be connected with the upper end of the process hole 230, so that the liquid inside the cartridge 22 can enter the dispensing head 232 through the injection hole 262, the leakage hole 224 and the process hole 230 in turn, and flow out through the dispensing head 232.

[0036] Two groups of hook-shaped plates 4 symmetrically arranged are fixedly installed on the rope loop 1, one end of the hook-shaped plate 4 is fixedly connected to a connecting sleeve 11, and two connecting heads 41 are fixedly installed on the connecting sleeve 11. The two connecting heads 41 are connected to one end of the hose 3 away from the liquid dispensing head 232, one of the connecting heads 41 is connected to a first liquid pipe 44 at one end away from the hose 3, and the other connecting head 41 is connected to a second liquid pipe 45 at one end away from the hose 3.

A dispensing tube 481 is provided inside the shell 47, a ratchet 48 is fixedly installed on the outer side above the dispensing tube 481, a rubber plate 480 is fixedly fitted on the surface of the ratchet 48, and a rubber strip 471 and a limiting plate 472 fixedly installed on the inner wall of the wheel shell 47 are provided on one side of the ratchet 48. The rubber strip 471 and the limiting plate 472 fit tightly together and the length of the rubber strip 471 is longer than the limiting plate 472. By providing the limiting plate 472, excessive deformation of the rubber strip 471 can be avoided. A plurality of sets of rotating plates 482 are fixedly installed at equal angles on the outer side below the dispensing tube 481, and a nozzle 483 connected to the inside of the dispensing tube 481 is provided between any two adjacent rotating plates 482. A limiting block 461 is fixedly installed on the upper end surface of the bottom of the wheel shell 47.

[0037] A protective shell 46 connected to the interior of the wheel shell 47 is fixedly installed on one side of the wheel shell 47, and the side wall of the protective shell 46 is in close contact with the inner wall of the heat-conducting shell 42. A plurality of groups of one-way plates 462 arranged obliquely are fixedly installed inside the protective shell 46, and a liquid outlet 463 is provided at one end of the protective shell 46 away from the wheel shell 47. A medicine outlet hole 421 connected to the interior of the heat-conducting shell 42 is opened at the bottom.

[0038] In order to facilitate observation of the content of the medicine liquid inside the medicine cartridge 22 , the medicine cartridge 22 is made of a transparent material, and a scale is provided on the side of the magnetic ring 23 , through which the approximate content of the medicine liquid inside the medicine cartridge 22 can be estimated.

[0039] The specific working principle of the present invention is as follows. When an injection operation is required, the user must first put the noose 1 on the horse's head according to the installation method of a conventional horse bit, and at the same time hook the hook plate 4 into the corner of the horse's mouth for injecting medicine (it can be used as a conventional horse bit without removing it after use). The cushion 2 is fixed to the horse's back with a strap 20 to prevent the horse from moving during the injection of medicine, which makes the injection operation inconvenient. When the fixed switch 221 is pulled upward, the limit shell 220 limits the fixed switch 221 to only rotate 90 degrees. Pulling the fixed switch 221 upward will also cause the limit rod 223 to rotate 90 degrees with the fixed switch 221, thereby releasing the displacement restriction of the magnetic ring 23 in the left and right directions (such as Figure 3 The magnetic ring 23 has magnetic force, which will attract the magnetic piston 26 inside the cartridge 22 to move synchronously (the principle is similar to that of a magnetic rodless cylinder), and the magnetic piston 26 divides the internal space formed by the cartridge 22 and the piston 251 into two parts, so the movement of the magnetic piston 26 will cause the volume of the two divided internal spaces to change. The limit rod 223 on the rotating shaft 222 is a pre-designed arrangement position, which can make the position where the magnetic piston 26 moves after being locked just divide the two spaces according to a certain proportion. The user only needs to move the magnetic ring 23 to the preset limit rod 223 locking position, then reset the fixed switch 221 and inject the medicine into the above two spaces through the two liquid inlets 225 to quickly complete the proportioning of different proportions of liquid medicine. At the same time, there is a scale on the side of the magnetic ring 23. By adding the liquid medicine in the two spaces in the cartridge 22 to the same height, the total liquid medicine can be quantitatively determined, which simplifies the complex proportioning and liquid division process. The position of the leakage hole 224 at the bottom of the cartridge 22 corresponds to the position of the upper limit rod 223, and after the magnetic ring 23 and the magnetic piston 26 move, except for the leakage hole 224 corresponding to the process hole 230, the rest will be blocked by the sealing block 231 to prevent leakage.

[0040] When the medicine liquid ratio is completed, the handle 242 is pulled at a uniform speed so that the two sliders 241 are displaced in the horizontal direction gradually approach the axis plate 233 at different speeds and finally reach the position of the longitudinal axis of the axis plate 233 at the same time (assuming that there is no restriction from the driven groove 252, pushing the handle 242 will eventually make the two sliders 241 and the center of the axis plate 233 move to the same longitudinal line, which means that the two sliders 241 will reach the contact position at the same time, but now there is the driven groove 252, which will make the two sliders 241 unable to move to the same longitudinal line as the center of the axis plate 233, but the intermediate movement process remains unchanged), so the sliding of the two sliders 241 will drive the driven groove 252 and then drive the two pistons 251 to approach the magnetic piston 26 at different speeds and finally fit to the side surface of the magnetic piston 26 at the same time. The ratio of the two spaces is constant, and the time to push the medicine is the same. Therefore, the same concentration will be maintained when the medicine is mixed in any time period to prevent the inability to fully and evenly mix in the horse's mouth and reduce the effect of the medicine. At the same time, the handle 242 is controlled so that although the two liquid medicines are sprayed at different rates, the total injection rate after mixing is consistent, and then the handle 242 can be pushed at a constant speed to achieve the effect of constant injection speed, preventing the horse from being frightened by the excessive injection rate. When the handle 242 is pushed, the ratio of the two internal spaces is always constant, so it can be stopped at any time for the next injection without the need for re-proportioning. The two liquid medicines will be ejected from the two injection holes 262 designed opposite to each other on the magnetic piston 26 (the sealing sleeve 261 clamps the magnetic piston 26 for sealing), and after passing through the matching leakage hole 224 and the process hole 230, the two liquid medicines will be evenly divided into two parts by the liquid separation head 232 and injected into the hook plate 4 on both sides.

[0041] The two kinds of liquid medicine enter into two connectors 41 through the hose 3 respectively. The connector 41 connects the first liquid pipe 44 and the second liquid pipe 45 in the hook plate 4. The liquid in the first liquid pipe 44 will pass through the ratchet 48 and enter the liquid dispensing pipe 481 and be discharged from the nozzle 483. The liquid discharged from the second liquid pipe 45 is opposite to the liquid discharged from the second liquid pipe 45, so it can reduce the water flow from colliding with the inner wall of the protective shell 46 to make a loud sound to alert the horse. The liquid medicine sprayed from the nozzle 483 and the second liquid pipe 45 collide and mix fully and drive the rotating plate 482 to rotate clockwise ( Fig. 9As shown in the direction, after rotating 180 degrees, it will pass through the one-way plate 462 and finally be discharged from the liquid outlet 463 (because the limiting block 461 is fixed on the upper end surface of the bottom of the wheel shell 47, the rotation of the rotating plate 482 will make the other three nozzles 483 except the nozzle 483 relative to the second liquid pipe 45 blocked from the inside to prevent the medicine from flowing back). Since the one-way plate 462 is fixed on the inner wall of the shorter side of the protective shell 46, the mixed medicine liquid will squeeze the one-way plate 462 to be discharged, and cling to the inner wall of the longer side of the protective shell 46. The inner wall of the longer side of the protective shell 46 clings to the inner wall of the heat-conducting shell 42, and the heat-conducting shell 42 clings to the flesh wall inside the horse's mouth. Therefore, the medicine liquid will be heated by the temperature of the horse's mouth to a relatively less irritating temperature during the process of coming out, making it more acceptable to the horse. The sprayed liquid medicine will mix with the horse's saliva coming in from the saliva hole 43 and finally be discharged from the medicine outlet hole 421. This design is to release the pressure when the liquid medicine is sprayed, so that the medicine slowly enters the horse's mouth and improves the horse's acceptance.

[0042] When the injection stops, the rotating plate 482 will stop rotating. A ratchet 48 is fixed on the upper end of the rotating plate 482. The ratchet 48 is a one-way rotating mechanism and can rotate clockwise, but cannot rotate counterclockwise under the action of the rubber strip 471 and the rubber plate 480, which can prevent the liquid medicine from flowing back and polluting the pipeline. The separation of the rubber strip 471 and the limiting plate 472 can make the rubber strip 471, which is a softer material, also play a limiting role. The rubber material is also used because it does not make a loud noise when rotating and colliding to alert the horse. At the same time, the one-way plate 462 can well block solid magazines from the outside to further prevent contamination of the internal liquid medicine. When the same horse needs to be injected with medicine again, it can be used directly without taking it out for cleaning.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
