Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of animal feeding devices, in particular to an animal medicine feeder. BACKGROUND

[0002] Due to the need for experiments, cages containing experimental mice are usually placed in a low-pressure and low-oxygen cabin (i.e., a simulated high-altitude environment) for experiments. Since the experimental process is relatively long, it is necessary to continuously feed water and medicine to the experimental mice during the experiment.

[0003] The utility model patent with the authorized announcement number CN216254651U provides an experimental mouse water feeder, which comprises a bottle body provided with an opening at an upper end and a bottle plug arranged at the opening of the bottle body and matched with the opening; a vertical through hole is arranged on the bottle plug, a metal water feeding pipe is sealingly installed in the through hole, the lower end of the metal water feeding pipe is in communication with the inner cavity of the bottle body, and the upper end of the metal water feeding pipe is provided with a water outlet; a water blocking ball is movably arranged in the water outlet, in a non-drinking water state, the water blocking ball sealingly cooperates with the water outlet to block the water outlet, and in a drinking water state, the experimental mouse can push open the water blocking ball to form a gap between the water blocking ball and the water outlet to make the water in the bottle body flow out from the water outlet through the metal water feeding pipe; the lower end of the bottle body is provided with an air pressure balancing assembly for connecting the external atmosphere of the bottle body with the inner cavity of the bottle body.

[0071] As shown in Figures 1-13 The present application provides an animal medicine feeder, which comprises a base 100, a water storage tank 200, a water outlet pipe assembly 300 and a water valve assembly 400.

[0072] The water storage tank 200 is fixedly installed on the top of the base 100, and the water storage tank 200 is provided with a water outlet. The water storage tank 200 comprises a tank body 210 and a tank cover 220, and the tank cover 220 is provided with a pressure balance hole 221. Under the action of the pressure balance hole 221, the air pressure in the tank body 210 can always be consistent with the air pressure outside. The first end of the water outlet pipe assembly 300 is fixedly connected with the water storage tank 200, and the second end freely extends downward. The drinking water valve assembly 400 is arranged at the second end of the water outlet pipe assembly 300, and the drinking water valve assembly 400 comprises a water blocking ball 410 and a third elastic member 420. The water blocking ball 410 is slidingly installed in the water outlet pipe assembly 300 and located at the second end of the water outlet pipe assembly 300. The third elastic member 420 is a spring, and the two ends of the third elastic member 420 are connected with the water blocking ball 410 and the water outlet pipe assembly 300 respectively. In a natural state, the third elastic member 420 has a tendency to move the water blocking ball 410 downward, so that the water blocking ball 410 abuts against the water outlet pipe assembly 300, thereby achieving the purpose of plugging the water outlet of the water outlet pipe assembly 300. When the experimental mouse needs to drink water, the experimental mouse can push open the water blocking ball 410 to form a gap between the water blocking ball 410 and the water outlet of the water outlet pipe assembly 300, so that the water in the water storage tank 200 flows out through the water outlet pipe assembly 300, thereby achieving the purpose of automatic feeding. These are all prior art, and will not be described in detail here. For details, please refer to the utility model patent with the authorization announcement number CN216254651U.

[0073] The animal medicine feeder provided by the application further comprises a controller 500, a timer 600 and a medicine feeding assembly.

[0074] The controller 500 is fixedly installed in the base 100. The timer 600 is fixedly installed in the base 100, and the timer 600 is electrically connected with the controller 500. The timer 600 is used for setting a medicine feeding time. It should be noted that the medicine feeding time mentioned here can be a time period for the experimental mouse to take medicine, or can be a starting time for the experimental mouse to take medicine. The medicine feeding assembly is arranged on the base 100 and / or the water storage tank 200, and the medicine feeding assembly is electrically connected with the controller 500. The medicine feeding assembly is used for feeding the prepared medicine liquid into the water outlet pipe assembly 300 according to the medicine feeding time set by the timer 600.

[0075] In use, after the time period for the experimental mouse to take medicine set by the timer 600 is reached, the medicine feeding assembly directly feeds the prepared medicine liquid into the water outlet pipe assembly 300 under the action of the medicine feeding assembly. This not only enables the experimental mouse to drink the medicine liquid first when drinking water, but also ensures that the experimental mouse will not take too much medicine in the time period, and also ensures the amount of medicine taken by the experimental mouse in the time period.

[0076] It should be noted that the medicament is put into the water outlet pipe assembly 300 by the medicament delivery assembly instead of being directly put into the water storage tank 200 or being stored in a storage tank connected with the water outlet pipe assembly 300. If the medicament is stored in a storage tank connected with the water outlet pipe assembly 300, the medicament in the storage tank will flow into the water outlet pipe assembly 300 and be drunk by the experimental mouse as soon as the experimental mouse drinks water, which will easily cause the experimental mouse to ingest too much medicament within the specified time, thereby causing harm to the experimental mouse. If the medicament is directly put into the water storage tank 200, the medicament will be diluted, the experimental mouse will ingest insufficient medicament within the specified time, and the quality of the medicament and water will be affected for a long time.

[0077] Therefore, by setting the timer 600 and the medicament delivery assembly, when the time period for the experimental mouse to take the medicament is reached, the medicament delivery assembly directly puts the medicament into the water outlet pipe assembly 300, so that the experimental mouse will drink the medicament first when drinking water, thereby achieving the purpose of satisfying the amount of medicament ingested by the experimental mouse within the specified time period.

[0078] In an embodiment, the water outlet pipe assembly 300 includes a first water outlet pipe 310, a second water outlet pipe 320, and a first valve structure 330.

[0079] The first water outlet pipe 310 is arranged in a transverse direction, and the first water outlet pipe 310 is fixedly connected with the water storage tank 200 and / or the base 100 and is in communication with the water outlet of the water storage tank 200. Specifically, in this embodiment, the first water outlet pipe 310 is fixedly connected with the water storage tank 200.

[0080] The second water outlet pipe 320 is L-shaped, and the second water outlet pipe 320 is fixedly connected with the water storage tank 200 and / or the base 100. Specifically, in this embodiment, the second water outlet pipe 320 is fixedly connected with the water storage tank 200. A first end of the second water outlet pipe 320 is arranged opposite to an end of the first water outlet pipe 310 away from the water storage tank 200, and a second end of the second water outlet pipe 320 freely extends downward, and the water valve assembly 400 is arranged at the second end of the second water outlet pipe 320.

[0081] The first valve structure 330 is arranged at the end of the first water outlet pipe 310 away from the water storage tank 200 and the first end of the second water outlet pipe 320, i.e., the opposite ends of the first water outlet pipe 310 and the second water outlet pipe 320.

[0082] The medicament delivery assembly includes a medicament storage unit 700, a storage unit 800, and a delivery unit.

[0083] The medicine storage unit 700 comprises a medicine storage shell 710 and a second valve structure 720. The medicine storage shell 710 is in a cylindrical shape, and has a hollow medicine storage cavity 711 with two open ends. Preferably, the sidewall of the medicine storage shell 710 is provided with a medicine injection port 712, and a gas nozzle 730 is arranged at the medicine injection port 712. In use, the staff can inject the prepared medicine into the medicine storage cavity 711 through the medicine injection port 712. The second valve structure 720 is provided in two, and arranged at the two ends of the medicine storage shell 710 respectively, and used to control the opening and closing of the two ends of the medicine storage cavity 711.

[0084] The storage unit 800 is used to store the medicine storage unit 700, and comprises a storage box 810. The storage box 810 is arranged in the longitudinal direction on the water storage tank 200 and / or the base 100, and fixedly connected with the water storage tank 200 and / or the base 100. Specifically, in the embodiment, the storage box 810 is fixedly connected with the water storage tank 200. The storage box 810 has a hollow storage cavity 811, and the length and width of the storage cavity 811 are adapted to the length and width of the medicine storage shell 710. It should be noted that, when the medicine storage shell 710 is in a cylindrical shape, the width herein refers to the outer diameter of the medicine storage shell 710. In use, a plurality of medicine storage units 700 can be stacked in the storage cavity 811 in the longitudinal direction.

[0085] The delivery unit is arranged on the base 100 and / or the water storage tank 200, and electrically connected with the controller 500. The delivery unit is used to deliver the medicine storage unit 700 storing the medicine in the storage box 810 to the position between the first water outlet pipe 310 and the second water outlet pipe 320. Specifically, when the medicine storage unit 700 is delivered to the position between the first water outlet pipe 310 and the second water outlet pipe 320, the two ends of the medicine storage unit 700 are sealed with the first water outlet pipe 310 and the second water outlet pipe 320 respectively. For example, elastic sealing rings are fixedly arranged at the opposite ends of the first water outlet pipe 310 and the second water outlet pipe 320.

[0086] When the medicine storage unit 700 is delivered to the position between the first water outlet pipe 310 and the second water outlet pipe 320, the first valve structure 330 and the second valve structure 720 are both opened.

[0087] In use, the staff prepares the medicine to be fed into the medicine liquid, and then injects the medicine liquid into the medicine storage shell 710 through the medicine injection port 712. Then, the staff puts a plurality of medicine storage units 700 storing the medicine liquid into the storage box 810, and sets the medicine delivery time (i.e. the medicine taking time of the experimental mice) by using the timer 600.

[0088] When the dosing time set by the timer 600 is reached, the controller 500 controls the conveying unit to convey one of the storage units 700 in the storage magazine 810 to between the first water outlet pipe 310 and the second water outlet pipe 320, and when the storage unit 700 is conveyed to between the first water outlet pipe 310 and the second water outlet pipe 320, the first valve structure 330 and the second valve structure 720 are both opened.

[0089] When the experimental mouse drinks water, the experimental mouse pushes away the water-blocking ball 410, and the liquid medicine in the storage unit 800 enters the second water outlet pipe 320, and finally flows out from the gap between the second end of the second water outlet pipe 320 and the water-blocking ball 410, and is drunk by the experimental mouse.

[0090] Preferably, the first water outlet pipe 310 is also provided with a one-way valve 340, under the action of the one-way valve 340, only the water in the water storage tank 200 is allowed to flow out from the first water outlet pipe 310, and the liquid medicine in the medicine storage shell 710 is not allowed to seep into the water storage tank 200 through the first water outlet pipe 310.

[0091] In one embodiment, the first valve structure 330 includes a first valve body 331, a first limiting ring 332, a first elastic member 333, and a first magnet 334.

[0092] The first valve body 331 is uniformly provided with a plurality of first water outlet holes around its own axis, and the first valve body 331 is slidingly arranged in the first water outlet pipe 310 or the second water outlet pipe 320. Specifically, the first valve body 331 of the first valve structure 330 arranged on the first water outlet pipe 310 is slidingly arranged in the first water outlet pipe 310, and the first valve body 331 of the first valve structure 330 arranged on the second water outlet pipe 320 is slidingly arranged in the second water outlet pipe 320.

[0093] The first limiting ring 332 is arranged in the first water outlet pipe 310 or the second water outlet pipe 320 and is fixedly connected with the first water outlet pipe 310 or the second water outlet pipe 320. Specifically, the first limiting ring 332 of the first valve structure 330 arranged on the first water outlet pipe 310 is arranged in the first water outlet pipe 310, and the first limiting ring 332 of the first valve structure 330 arranged on the second water outlet pipe 320 is arranged in the second water outlet pipe 320. And the first water outlet hole is located between the inner diameter of the first limiting ring 332 and the inner diameter of the first water outlet pipe 310 or the second water outlet pipe 320.

[0094] The two ends of the first elastic member 333 are connected with the first valve body 331 and the first water outlet pipe 310 or the second water outlet pipe 320 respectively, and in the natural state, the first elastic member 333 has a tendency to move the first valve body 331 to the direction close to the first limiting ring 332. Specifically, the first elastic member 333 is a spring. Then in the natural state, under the action of the first elastic member 333, the first elastic member 333 makes the first valve body 331 abut against the first limiting ring 332, thereby achieving the purpose of blocking the opposite ends of the first water outlet pipe 310 and the second water outlet pipe 320. The first magnet 334 is fixedly embedded on the first valve body 331.

[0095] The second valve structure 720 includes a second valve body 721, a second limiting ring 722, a second elastic member 723 and a second magnet 724.

[0096] The second valve body 721 is uniformly provided with a plurality of second water outlet holes around its own axis, and the second valve body 721 is slidingly arranged in the medicine storage shell 710. The second limiting ring 722 is arranged in the medicine storage shell 710 and fixedly connected with the medicine storage shell 710, specifically, the second limiting ring 722 is arranged at the end of the medicine storage shell 710, and the second water outlet hole is located between the inner diameter of the second limiting ring 722 and the inner diameter of the medicine storage shell 710.

[0097] The two ends of the second elastic member 723 are connected with the second valve body 721 and the medicine storage shell 710 respectively, and in the natural state, the second elastic member 723 has a tendency to move the second valve body 721 to the direction close to the second limiting ring 722. Specifically, the second elastic member 723 is a spring, and in the natural state, under the action of the second elastic member 723, the second elastic member 723 makes the second valve body 721 abut against the second limiting ring 722, thereby achieving the purpose of blocking the two ends of the medicine storage shell 710. The second magnet 724 is fixedly embedded on the second valve body 721. The magnetic properties of the opposite sides of the first magnet 334 and the second magnet 724 are the same.

[0098] When the conveying unit conveys the medicine storage unit 700 to the space between the first water outlet pipe 310 and the second water outlet pipe 320, the magnetic repulsion will be generated between the first magnet 334 and the second magnet 724 due to the opposite magnetic properties of the opposite sides of the first magnet 334 and the second magnet 724. Under the action of the magnetic repulsion, the first valve body 331 is moved away from the first limiting ring 332 against the elastic force of the first elastic member 333, and the second valve body 721 is moved away from the second limiting ring 722 against the elastic force of the second elastic member 723, so that the first water outlet pipe 310, the medicine storage shell 710 and the second water outlet pipe 320 are sequentially communicated. When the experimental mouse pushes away the water-blocking ball 410 to drink water, the medicine liquid and water can flow out from the gap between the water-blocking ball 410 and the water outlet of the water outlet pipe assembly 300 through the first water outlet pipe 310, the medicine storage shell 710 and the second water outlet pipe 320 to be drunk by the experimental mouse.

[0099] The first valve structure 330 and the second valve structure 720 have simple structure and reasonable design, and can be automatically opened when the first valve structure 330 and the second valve structure 720 are corresponded.

[0100] Preferably, the first magnet 334 and / or the second magnet 724 is an electromagnet, and the electromagnet is electrically connected with the controller 500. If both the first magnet 334 and the second magnet 724 are permanent magnets, the first valve structure 330 and the second valve structure 720 will be opened in advance under the action of the magnetic repulsion between the first magnet 334 and the second magnet 724 when the medicine storage unit 700 is moved to the space between the first water outlet pipe 310 and the second water outlet pipe 320, so that the medicine liquid and water are leaked, and the resources are wasted.

[0101] If at least one of the first magnet 334 and the second magnet 724 is an electromagnet, the electromagnet is only powered when the medicine storage unit 700 is conveyed to the space between the first water outlet pipe 310 and the second water outlet pipe 320, so that the leakage of the medicine liquid and water is avoided, and the purpose of saving resources is achieved.

[0102] When the second magnet 724 is an electromagnet, the end portions of the first water outlet pipe 310 and the second water outlet pipe 320 are provided with fixed electrodes, and the end portion of the medicine storage shell 710 is provided with a movable electrode. When the conveying unit conveys the medicine storage unit to the space between the first water outlet pipe 310 and the second water outlet pipe 320, the fixed electrodes and the movable electrode are in contact, so that the second magnet can be powered.

[0103] In an embodiment, the conveying unit comprises a conveying mechanism 910 and a pushing mechanism 920.

[0104] The conveying mechanism 910 comprises a carrier 911 and a motor 912.

[0105] The carrier 911 is rotationally connected with the base 100 and / or the water storage tank 200, and specifically, in this embodiment, the carrier 911 is rotationally connected with the base 100. The carrier 911 is provided with n carrier holes around its own rotation center line, the carrier holes being adapted to the storage units 700, wherein n≥2. Specifically, at any time, one carrier hole corresponds to the first water outlet pipe 310, and another carrier hole corresponds to the storage box 810.

[0106] The motor 912 is fixedly arranged on the water storage tank 200 and / or the base 100, and specifically, in this embodiment, the motor 912 is fixedly arranged on the base 100. The motor 912 is electrically connected with the controller 500, and the power output shaft of the motor 912 is in transmission connection with the power input end of the carrier 911, and specifically, the power output shaft of the motor 912 is in transmission connection with the power input end of the carrier 911 through a gear structure. The motor 912 is used to drive the carrier 911 to rotate by a preset angle α, wherein α=360° / n. Preferably, the motor 912 is a step motor or a servo motor.

[0107] The pushing mechanism 920 is used to push the storage units 700 in the storage box 810 into the carrier holes. Specifically, the bottom end of the storage box 810 is provided with a transversely-through pushing hole 812, the pushing mechanism 920 is arranged at the first end of the pushing hole 812, and the carrier 911 is located at the second end of the pushing hole 812.

[0108] In use, first, the pushing mechanism 920 pushes the storage units 700 in the storage box 810 into the carrier holes on the carrier 911, and then the motor 912 drives the carrier 911 to rotate by an angle α, so as to deliver the storage units 700 containing the liquid medicine between the first water outlet pipe 310 and the second water outlet pipe 320.

[0109] The delivery unit of this structure is simple in structure and reasonable in design.

[0110] In one embodiment, the pushing mechanism 920 includes a pushing slider 921 and an electric push rod 922.

[0111] The push slider 921 is slidingly connected with the storage box 810. Specifically, the push slider 921 is slidingly installed in the push hole 812, and the push slider 921 can reciprocate linearly along the axial direction of the push hole 812 between a first working position and a second working position. Specifically, when the push slider 921 is in the first working position, the push slider 921 is located at the first end of the push hole 812, and when the push slider 921 is in the second working position, the push slider 921 is located at the second end of the push hole 812. In use, the push slider 921 moves from the first end to the second end of the push hole 812, so as to push the storage unit 700 in the storage box 810 into the bearing hole.

[0112] The electric push rod 922 is fixedly arranged on the base 100 and / or the water tank 200, and the electric push rod 922 is electrically connected with the controller 500. The power output shaft of the electric push rod 922 is fixedly connected with the push slider 921. The electric push rod 922 is used to drive the push slider 921 to reciprocate linearly between the first working position and the second working position.

[0113] In use, the electric push rod 922 extends, so as to move the push slider 921 from the first end to the second end of the push hole 812, and then push the storage unit 700 in the storage box 810 into the bearing hole. At the same time, the storage unit 700 pushed into the bearing hole pushes the original storage unit 700 in the bearing hole out of the bearing hole.

[0114] After the storage unit 700 is pushed into the bearing hole, the electric push rod 922 retracts, so as to drive the push slider 921 back to the original position. Under the action of its own gravity, the storage unit 700 in the storage box 810 falls into the push hole 812, to be pushed into the bearing hole.

[0115] In an embodiment, a collection box 930 and a flow guide plate 940 are further included.

[0116] The collection box 930 is arranged in a drawer structure with the base 100, and is used to collect the storage unit 700 falling from the bearing member 911. The flow guide plate 940 is fixedly connected with the base 100 and / or the water tank 200, and is used to guide the storage unit 700 falling from the bearing member 911 into the collection box 930.

[0117] In use, the storage unit 700 falling from the bearing member 911 falls onto the flow guide plate 940, and under the action of the flow guide plate 940, falls into the collection box 930 along the flow guide plate 940.
