[0037] As Figure 1 and Figure 4As shown, the feeding training device comprises a box body 100 and a feeding training module 200, the box body 100 comprises a fourth side plate 150 provided with a second through hole A2, a third through hole A3 and a fourth through hole A4, the feeding training module 200 comprises a water supply unit 210, a pressure rod unit 220, a sound stimulation unit 230 and a control unit 240, the water supply unit 210, the pressure rod unit 220, the sound stimulation unit 230 and the control unit 240 are arranged on the fourth side plate 150, and at least part of the water supply unit 210, the pressure rod unit 220 and the sound stimulation unit 230 respectively pass through the second through hole A2, the third through hole A3 and the fourth through hole A4 into the box body 100, and the water supply unit 210, the pressure rod unit 220 and the sound stimulation unit 230 are respectively connected with the control unit 240.

[0038] The water supply unit 210 comprises a water outlet nozzle 211, a pump body 212, a water storage pipe 213 and a water outlet pipe 214, the water outlet nozzle 211 passes through the third through hole A3 into the box body 100, the pump body 212 is connected with the water outlet nozzle 211 and the water storage pipe 213 through the water outlet pipe 214, and the pump body 212 is connected with the control unit 240; the pressure rod unit 220 comprises a pressure rod 221, a pressure sensor 222 and a pressure rod table 223, one end of the pressure rod 221 passes through the second through hole A2 into the box body 100, the other end of the pressure rod 221 is connected with the pressure sensor 222, one end of the pressure sensor 222 away from the pressure rod 221 is arranged on the pressure rod table 223, the pressure sensor 222 is connected with the control unit 240, the sound stimulation unit 230 is connected with the box body through the fourth through hole A4, the sound stimulation unit 230 is connected with the control unit 240, the sound stimulation unit 230 is generally a loudspeaker, and the control unit 240 is generally a single-chip microcomputer.

[0039] The training process is that the experimental body presses the pressure rod 221 and stays for a certain period of time, the control unit 240 receives the pressure signal transmitted by the pressure sensor 222, then the control unit 240 controls the sound stimulation unit 230 to give a high-frequency sound prompt, and controls the pump body 212 to start to make the water outlet nozzle 211 give water. When the experimental body licks the water outlet nozzle 211, the water outlet nozzle 211 gives a licking signal, the licking signal is transmitted to the control unit 240, the control unit 240 receives the licking signal, then controls the sound stimulation unit 230 to give a medium-frequency sound prompt, and the single test is ended. If the experimental body does not press the pressure rod 221 or presses the pressure rod 221 but does not stay for enough time after the single test starts, the control unit 240 receives the pressure signal transmitted by the pressure sensor 222, then controls the sound stimulation unit 230 to give a low-frequency sound prompt, and controls the pump body 212 to be in a closed state so that the water outlet nozzle 211 has no water, after waiting for a certain period of time, the control unit 240 controls the sound stimulation unit 230 to give a medium-frequency sound prompt, and the single test is ended.

[0040] The single test is repeated, and a certain time interval is set between the single test, and when the number of single test repetitions reaches a certain degree or the number of licking times of the experimental body reaches a certain proportion, it is considered that the experimental body has learned the pressure rod behavior task paradigm.

[0041] When the experimental body learns the task paradigm, since the experimental body needs to be connected with a wired data connection, the experimental body needs to be transferred from the feeding and training device to the collection device for experimental data collection of the experimental body. However, the transfer of the experimental body will affect the environmental factors of the experimental body, thereby causing errors in the feeding, training environment and data collection environment.

[0042] As shown in Figure 1 The present application provides an experimental device, which comprises a box body 100, a feeding and training module 200 and a signal collection module (not shown in the figure). The box body 100 is used to accommodate the experimental body, and the box body 100 is provided with a first through hole A1; the feeding and training module 200 is fixedly arranged on the box body 100, and at least part of the feeding and training module 200 extends into the box body 100, and the feeding and training module 200 is used to train the experimental body; the signal collection module comprises a data transmission line (not shown in the figure), the data transmission line enters the box body 100 through the first through hole A1, and the data transmission line is fixed on the experimental body.

[0043] Based on the above setting, the data transmission line of the signal collection module enters the box body 100 through the first through hole A1 on the box body 100 and is fixed on the experimental body. In this way, the signal collection module can directly collect the information of the experimental body in the feeding and training module 200 without transferring the experimental body, thereby ensuring the consistency of the feeding, training environment and data collection environment, and also avoiding the time cost of transferring the experimental body.

[0044] In an embodiment, referring to Figure 1 and Figure 5 The experimental device further comprises an auxiliary collection module 300, the auxiliary collection module 300 comprises an auxiliary body 310 and a length adjusting member 320 fixed on the auxiliary body 310, the data transmission line (not shown in the figure) is connected with the length adjusting member 320, and the length adjusting member 320 is used to increase or decrease the length of the data transmission line located in the box body 100 when the experimental body moves.

[0045] If the length adjusting member 320 is not set, when the experimental body moves in the box 100, more data transmission lines will be dragged into the box 100, and the data transmission lines will be placed at the bottom of the box 100. During the experiment, the experimental body may gnaw the data transmission lines placed at the bottom of the box 100, and the data transmission lines will be damaged. In the embodiment, the length adjusting member 320 is set, and the length adjusting member 320 can increase or decrease the length of the data transmission lines in the box 100 along with the movement of the experimental body, so that the data transmission lines connected to the experimental body always maintain a relative length and will not fall to the bottom of the box 100, thereby avoiding the damage of the data transmission lines caused by the gnawing of the experimental body.

[0046] In the embodiment, referring to Figure 1 and Figure 5 , the length adjusting member 320 is an elastic member, and the data transmission lines are fixed to the elastic member. The elastic member herein can be an elastic rope, an elastic band, a spring, or other elastic components. When the experimental body moves away from the first through hole A1, part of the data transmission lines enters the box 100, the elastic member is elongated and provides a back-up force to the data transmission lines. Because of the back-up force, the data transmission lines will not fall to the bottom of the box 100, thereby avoiding the damage of the data transmission lines caused by the gnawing of the experimental body. When the experimental body moves towards the first through hole A1, the back-up force will pull the part of the data transmission lines that have entered the box 100 away from the box 100, so that the data transmission lines gradually return to the initial state.

[0047] In summary, whether the experimental body moves away from the first through hole A1 or moves towards the first through hole A1, the data transmission lines will not fall to the bottom of the box 100, thereby avoiding the damage of the data transmission lines caused by the gnawing of the experimental body.

[0048] Further, referring to Figure 1 and Figure 5 , the auxiliary body 310 further includes a first fixing member 311 provided with a groove 311a, and the elastic member is clamped in the groove 311a.

[0049] In the embodiment, the elastic member is fixed by the groove 311a, which has a simple structure, low cost, and is easy to set. Of course, in other embodiments, other fixing devices can also be used to fix the elastic member, such as fixing clips, fixing locks, etc.

[0050] Of course, in other embodiments, other structures can also be used to increase or decrease the length of the data transmission lines in the box 100 along with the movement of the experimental body. For example, the length adjusting member includes a driving part and a fixed part, the data transmission lines are fixed to the fixed part, and the driving part drives the fixed part to move, thereby increasing or decreasing the length of the data transmission lines in the box 100.

[0051] For example, the driving part can be a rotating motor, the fixed part includes a fixing member, a gear, and a rack, the data transmission line is fixed on the fixing member, the rack is fixed in the length direction of the fixing member, the rotating motor is arranged in cooperation with the gear, and the gear and the rack are arranged correspondingly. When the rotating motor rotates, the rotating motor can drive the gear to rotate, thereby driving the rack to move, and further driving the fixing member to move in the length direction thereof. Therefore, the rotating motor can drive the fixing member to move away from or close to the first through hole A1, so that the data transmission line located in the box body 100 maintains an appropriate length, so that the data transmission line will not fall to the bottom of the box body 100, thereby avoiding damage caused by the experimental body gnawing the data transmission line.

[0052] In addition, the driving part can also be a vertical linear displacement device. The vertical linear displacement device directly drives the fixed part to move away from or close to the first through hole A1 in the vertical direction, so that the data transmission line located in the box body 100 maintains an appropriate length, so that the data transmission line will not fall to the bottom of the box body 100, thereby avoiding damage caused by the experimental body gnawing the data transmission line. The driving part can also be a horizontal linear displacement device. The horizontal linear displacement device directly drives the fixed part to move away from or close to the first through hole A1 in the horizontal direction, so that the data transmission line located in the box body 100 maintains an appropriate length, so that the data transmission line will not fall to the bottom of the box body 100, thereby avoiding damage caused by the experimental body gnawing the data transmission line. The vertical linear displacement device and the horizontal linear displacement device can both adopt a hydraulic device.

[0053] For another example, the driving part is a driving spring, the fixed part includes a first fixing member and a second fixing member, the first fixing member and the second fixing member are arranged at an angle, and the spring is arranged at the angle and connected with the first fixing member and the second fixing member respectively. The data transmission line is fixed on the first fixing member, and the second fixing member is fixed externally. When the experimental body moves, the first fixing member is driven to rotate through the data transmission line, thereby changing the angle between the first fixing member and the second fixing member, and further driving the spring to stretch and contract. Therefore, the data transmission line located in the box body 100 can maintain an appropriate length, so that the data transmission line will not fall to the bottom of the box body 100, thereby avoiding damage caused by the experimental body gnawing the data transmission line.

[0054] It should be noted that in other embodiments, the first through hole can also not be provided, as long as the length of the data transmission line located in the box body 100 is controlled to be within the protection scope of the present application.

[0055] In an embodiment, with reference to Figure 1 and Figure 5As shown, the auxiliary body 310 further comprises a second fixing member 312, and the signal acquisition module comprises a camera 410 configured to acquire a position image of the experimental body, and the camera 410 is arranged on the second fixing member 312. The surface of the box body 100 corresponding to the camera 410 is transparent.

[0056] Since the surface of the box body 100 corresponding to the camera 410 is transparent, the camera 410 can acquire image information in the box body 100 to obtain a position image of the experimental body. In combination with the driving part (not shown in the figure) and the fixing part in the above embodiment, the length of the data transmission line in the box body 100 can be more accurately controlled. For example, the camera 410 periodically acquires image information in the box body 100. Assuming that the distance L1 between the experimental body and the first through hole A1 at T1, and the distance L2 between the experimental body and the first through hole A1 at T2, when the absolute value of the difference between L2 and L1 is greater than a preset value, the driving part is started to drive the fixing part to move. In this embodiment, the distance of the fixing part moving is the difference between L2 and L1. At the same time, when the difference between L2 and L1 is positive, the fixing part moves close to the first through hole A1; when the difference between L2 and L1 is negative, the fixing part moves away from the first through hole A1. Through the above setting, the length of the data transmission line in the box body 100 can be more accurately controlled. It should be noted that as long as the time difference between T1 and T2 is small enough, the experimental body will not feel that it is pulled by the data transmission line.

[0057] The camera 410 acquires image information in the box body 100, and can also obtain the scene when the experimental body is fed and trained, so as to timely find the condition of the experimental body, such as the occurrence of the experimental body being sick or the abnormal physiological state of the experimental body, and the operator can find it at the first time.

[0058] It should be further noted that the camera 410 is generally arranged at the top of the box body 100, and therefore the top of the box body 100 is transparent. Therefore, the bottom surface opposite to the top can also be set to be the color opposite to that of the experimental body, for example, the experimental body is black, and the bottom surface is white. Since the contrast is very high, the camera 410 can capture more obvious image information, and the operator can also distinguish the box body 100 and the experimental body more easily.

[0059] In an embodiment, as shown in the figure, Figure 5 The auxiliary body 310 comprises a fixing column 313, the first fixing member 311 and the second fixing member 312 are fixed to the fixing column 313 through a connecting member 314, and the part of the connecting member 314 located on the fixing column 313 is cylindrical and matches the diameter of the fixing column 313, and the connecting member 314 can rotate around the fixing column 313.

[0060] Since the connecting piece 314 can rotate around the fixing column 313, and the first fixing piece 311 and the second fixing piece 312 are fixed to the fixing column 313 through the connecting piece 314, the first fixing piece 311 and the second fixing piece 312 can also rotate around the fixing column 313 under the driving of the connecting piece 314. Since the length adjusting piece 320 and the camera 410 are respectively fixed on the first fixing piece 311 and the second fixing piece 312, the relative position relationship between the length adjusting piece 320, the camera 410 and the box 100 can be adjusted by rotating around the fixing column 313.

[0061] The length adjusting piece 320 and the first fixing piece 311 will be rotated or shaken when the experimental body moves. If the length adjusting piece 320 and the camera 410 are both arranged on the first fixing piece 311, the camera 410 will also be rotated or shaken, which will affect the captured pattern information. In the embodiment, the length adjusting piece 320 and the camera 410 are respectively arranged on the first fixing piece 311 and the second fixing piece 312, and the second fixing piece 312 will not be affected by the first fixing piece 311, so that the above-mentioned rotation or shaking problem can be avoided, and stable pattern information can be captured.

[0062] Further, a buffer can be arranged at the connection between the length adjusting piece 320 and the first fixing piece 311, so as to reduce the rotation or shaking generated when the experimental body moves. The buffer can be shock-absorbing cotton, shock-absorbing spring, etc. In the above-mentioned embodiment, the length adjusting piece 320 is an elastic piece, and the elastic piece is clamped in the groove 311a. The buffer can be arranged in the groove 311a, so as to reduce the rotation or shaking generated when the experimental body moves.

[0063] In the embodiment, the first fixing piece 311 and the second fixing piece 312 can be connected through a connecting piece, so that the first fixing piece 311 and the second fixing piece 312 can synchronously rotate.

[0064] When the experimental body moves, the length adjusting piece 320 and the first fixing piece 311 are first rotated, and then the second fixing piece 312 and the camera 410 fixed on the second fixing piece 312 are moved, so that the camera 410 can move following the movement of the experimental body, thereby realizing the effect of following the experimental body.

[0065] Since the first fixing member 311 and the second fixing member 312 have a certain weight, and the length adjusting member 320 and the camera 410 fixed thereon also have a weight, it is easy to cause the falling problem by only relying on the friction force between the connecting member 314 and the fixing column 313 to provide support. The embodiment provides a support member arranged below the connecting member 314 to provide additional support force. For example, a support rod is arranged to abut against the bottom of the connecting member 314 to prevent it from falling.

[0066] In an embodiment, referring to Figures 1-3 The box 100 includes an outer box 100A and an inner box 100B. The outer box 100A includes a box body having a first opening 160 and a cover plate 110 arranged on the first opening 160. A first through hole A1 is arranged on the cover plate 110. The inner box 100B is arranged in the outer box 100A and is used to accommodate experimental subjects. The box body includes a first side plate 120, a second side plate 130, a third side plate 140, and a fourth side plate 150. The volume of the inner box 100B is smaller than the volume of the outer box 100A.

[0067] Since the experimental subjects need to be fed and trained in the box 100, the box 100 needs to be cleaned frequently. If only one layer of the box 100 is arranged, the box 100 needs to be opened, and then the inside of the box 100 needs to be cleaned, which requires a lot of time. The embodiment arranges the outer box 100A and the inner box 100B. When cleaning is needed, the inner box 100B only needs to be taken out of the outer box 100A, and the inner box 100B can be directly cleaned, which can greatly reduce the cleaning time.

[0068] In an embodiment, referring to Figure 1 and Figure 4 The box body further includes a second opening 170 arranged on the side and a third side plate 140. The third side plate 140 can be switched between a first state and a second state. When the third side plate 140 is in the first state, the third side plate 140 closes the second opening 170. When the third side plate 140 is in the second state, the third side plate 140 is separated from the second opening 170, and the inner box 100B communicates with the outside through the second opening 170.

[0069] Through the above arrangement, when the third side plate 140 is in the first state, the second opening 170 is closed, and thus the box body can wrap the inner box 100B, thereby preventing the experimental subjects from escaping from the second opening 170. When the third side plate 140 is in the second state, the second opening 170 is opened, and the inner box 100B can be taken out or put in through the second opening 170, thereby the inner box 100B can be cleaned.

[0070] Based on the above setting, in the present embodiment, the third side plate 140 here can also be arranged under the cover plate 110, when the third side plate 140 needs to be converted into the second state, the cover plate 110 can be removed first, and then the third side plate 140 is converted into the second state. It can be known that the third side plate 140 is pressed by the cover plate 110, which can prevent the third side plate 140 from being opened by the experimental object, so as to cause the experimental object to escape.

[0071] Further, referring to Figure 1 and Figure 4 It is shown that the fourth side plate 150 and the inner box body 100B side wall corresponding to the fourth side plate 150 are both provided with a second through hole A2, and the feeding and training module 200 includes a pressing rod 221, the pressing rod 221 extends into the inner box body 100B through the second through hole A2; the fourth side plate 150 and the inner box body 100B side wall corresponding to the fourth side plate 150 are both provided with a third through hole A3, and the feeding and training module 200 further includes a water outlet nozzle 211, the water outlet nozzle 211 extends into the inner box body 100B through the third through hole A3. The second opening 170 is arranged opposite to the fourth side plate 150. In other embodiments, the fourth side plate 150 and the inner box body 100B side wall corresponding to the fourth side plate 150 are both provided with a second through hole A2, and the feeding and training module 200 includes a pressing rod 221, the pressing rod 221 extends into the inner box body 100B through the second through hole A2, or the fourth side plate 150 and the inner box body 100B side wall corresponding to the fourth side plate 150 are both provided with a third through hole A3, and the feeding and training module 200 further includes a water outlet nozzle 211, the water outlet nozzle 211 extends into the inner box body 100B through the third through hole A3. The second opening 170 is arranged opposite to the fourth side plate 150.

[0072] In the present embodiment, the pressing rod 221 extends into the inner box body 100B through the second through hole A2 and the water outlet nozzle 211 extends into the inner box body 100B through the third through hole A3, so that the inner box body 100B in the present embodiment is difficult to be taken out or entered from the first opening 160. Therefore, the second opening 170 is arranged opposite to the fourth side plate 150 in the present embodiment, so that the inner box body 100B can be taken out or entered along the direction in which the pressing rod 221 and the water outlet nozzle 211 extend.

[0073] In an embodiment, referring to Figure 1 and Figure 4 It is shown that the cover plate 110 includes a first plate 111 and a second plate 112, the first plate 111 and the second plate 112 cooperate to close or open the first opening 160, a part of the first through hole A1 is arranged on the first plate 111, and another part is arranged on the second plate 112. The first plate 111 and the second plate 112 can be connected to the first side plate 120 and the second side plate 130 respectively through metal hinges.

[0074] If the first through hole A1 is only arranged on the first plate 111 or the second plate 112, the experimental body cannot be taken out from the inner box 100B when the data transmission line is connected to the experimental body, and if the end of the data transmission line connected to the experimental body is provided with a device larger than the first through hole A1, the first through hole A1 cannot be penetrated, and the experimental body cannot be connected. In the arrangement of the embodiment, when the first plate 111 and the second plate 112 open the first opening 160, the first through hole A1 is also opened, and the first through hole A1 can be understood as being enlarged to the first opening 160. The experimental personnel can take out the experimental body connected with the data transmission line from the inner box 100B, or connect the device larger than the first through hole A1 to the experimental body.

[0075] Further, the first plate 111 and the second plate 112 can also be provided with a locking member matched with each other, so that when they are matched with each other to close, they cannot be pushed open by the experimental body, so that the experimental body escapes from the box 100.

[0076] Further, the first plate 111 and the second plate 112 can also be provided with a locking member matched with each other, so that when they are matched with each other to close, they cannot be pushed open by the experimental body, so that the experimental body escapes from the box 100.

[0077] Because the first plate 111 and the second plate 112 have a certain thickness, when the first plate 111 and the second plate 112 are closed to each other, there will be a certain gap between the first plate 111 and the second plate 112. When the data transmission line is thin enough, the data transmission line will enter the gap under the driving of the experimental body, so that the length adjusting member 320 fails. Therefore, the blocking member arranged here can prevent the data transmission line from entering the gap under the driving of the experimental body, and ensure the stability of the length adjusting member 320.

[0078] In an embodiment, as shown in FIGS. 1 to 3, the outer box 100A and the inner box 100B are matched with each other. Figure 1 and Figure 4 As shown in FIGS. 1 to 3, at least one side surface of the outer box 100A and the inner box 100B is made of transparent material. The transparent material can be transparent glass.

[0079] Through the above arrangement, the experimental personnel can observe the experimental body in the inner box 100B through the transparent material on the side surface.

[0080] In the present application, the structural embodiments and the method embodiments can be complementary to each other without conflict.
