[0022] Embodiments of the present application are described in detail below with reference to the attached drawing figures, wherein the same or like reference numerals and characters are used throughout the drawings and the following detailed description is intended to be read in conjunction with the accompanying drawings. The following description is intended to explain and enable not limit the application. Embodiments of the present application include all changes, modifications and equivalents that fall within the spirit and scope of the appended claims.

[0023] It should be noted that all directionality indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative position relationship, movement condition, etc. between components in a certain posture. If the certain posture changes, the directionality indications also change accordingly.

[0024] It should also be noted that when a component is referred to as "fixed to" or "provided on" another component, it can be directly on the other component or can have a middle component. When a component is referred to as "connected to" another component, it can be directly connected to the other component or indirectly connected to the other component through a middle component.

[0025] The distance between the first detection point and the second detection point in the embodiments of the present application is in a small first preset range, and whether the first detection point and the second detection point are touched is detected by the laser beams of the first photoelectric opposite radiation tube and the second photoelectric opposite radiation tube respectively, so that the micro-current is prevented from entering the animal body, and the accuracy of animal behavior training is improved.

[0026] Figure 1 is a top view of the detection device provided by the first embodiment of the present application. Figure 2 is another top view of the detection device provided by the first embodiment of the present application. Figure 1 and Figure 2 The detection device comprises a first photoelectric opposite radiation tube 1, a second photoelectric opposite radiation tube 2, a first detection point 3 and a second detection point 4.

[0027] In the embodiment of the present application, the first detection point 3 and the second detection point 4 independently receive signals. In the animal behavior training related to water supply, the first detection point 3 is the first water nozzle, and the second detection point 4 is the second water nozzle. Water is hung in the form of water droplets at the first water nozzle and the second water nozzle, and the animal licks the first water nozzle or the second water nozzle according to the instruction of the behavior training. The first water nozzle and the second water nozzle receive the action of licking by the animal. According to the size of the animal to be trained, the distance between the first detection point 3 and the second detection point 4 is within a first preset range. For example, when the animal is a mouse or a rat, the distance between the first detection point 3 and the second detection point 4 is about 5.5 mm. When the animal is fixed on the central axis of the first detection point 3 and the second detection point 4 and close to the two detection points (i.e., the two detection points are located in front of the left and right of the animal respectively), the animal can lick the first detection point 3 and the second detection point 4 respectively, but cannot lick them at the same time. According to different requirements of the animal behavior training, the first detection point 3 and the second detection point 4 can also receive other actions of the animal, which are not limited herein. The first photoelectric transceiver tube 1 includes a transmitting end and a receiving end, which are opposite to each other and form a laser beam therebetween. The second photoelectric transceiver tube 2 is the same as the first photoelectric transceiver tube 1, which is not described herein again. The laser beam of the first photoelectric transceiver tube 1 is close to the first detection point 3, and the distance is within a second preset range, which is used to detect the licking of the first detection point 3. The laser beam of the second photoelectric transceiver tube 2 is close to the second detection point 4, and the distance is within a third preset range, which is used to detect the licking of the second detection point 4. When the animal licks the first water nozzle, the laser beam of the first photoelectric transceiver tube 1 is interrupted, and the action of licking by the animal is detected and the number of licking is recorded. When the animal licks the second water nozzle, the laser beam of the second photoelectric transceiver tube 2 is interrupted, and the action of licking by the animal is detected and the number of licking is recorded.

[0028] Figure 3 is a schematic view of the body provided by the first embodiment of the present application. In order to fix the parts, the detection device further includes a body 5. The body 5 includes a first fixing seat 51, a second fixing seat 52, a third fixing seat 53, a fourth fixing seat 54, a first channel 55 and a second channel 56. The first fixing seat 51 and the second fixing seat 52 are used to fix the transmitting end and the receiving end of the first photoelectric transceiver tube 1, and the third fixing seat 53 and the fourth fixing seat 54 are used to fix the transmitting end and the receiving end of the second photoelectric transceiver tube 2. The end of the first channel 55 is used to fix the first water nozzle, and the end of the second channel 56 is used to fix the second water nozzle. Preferably, the first channel 55 and the second channel 56 are hollow, and water can be guided from the other end of the first channel 55 to the first water nozzle and from the other end of the second channel 56 to the second water nozzle. According to the licking needs of the animal, the shape of the first water nozzle and the second water nozzle is set, such as an olive type, and the end facing the animal is a flat end face.

[0029] In the embodiment of the present application, the distance between the center point of the first water nozzle end face and the center point of the second water nozzle end face is within a first preset range, such as 5-6 mm. The distance between the laser beam of the first photoelectric counter 1 and the center point of the first water nozzle end face is within a second preset range, such as 0.5-0.7 mm. The distance between the laser beam of the second photoelectric counter 2 and the center point of the second water nozzle end face is within a third preset range, such as 0.5-0.7 mm. Preferably, the second preset range and the third preset range are equal, such as both being 0.5 mm. According to the size of the trained animal, the appropriate first preset range, second preset range and third preset range are set, which can not only ensure that the animal can lick the two detection points in the left front and right front respectively, but also ensure that the animal will not break the laser beam of the other detection point when licking one detection point, thereby ensuring the accuracy of the animal behavior training.

[0030] When the size of the trained animal is small, the distance between the first detection point 3 and the second detection point 4 is small, and the distance between the laser beam of the first photoelectric counter 1 and the first detection point 3, the distance between the laser beam of the second photoelectric counter 2 and the second detection point 4 are also relatively small, while the first photoelectric counter 1 and the second photoelectric counter 2 are relatively large. Figure 4 is another top view of the detection device provided by the first embodiment of the present application. As shown in Figure 4 In order to reasonably arrange the components, the laser beam of the first photoelectric counter 1 and the laser beam of the second photoelectric counter 2 intersect to form an intersection point, which is located on the median line of the line connecting the first detection point 3 and the second detection point 4 and away from the animal. When the first detection point 3 and the second detection point 4 are water nozzles, preferably, the distance between the line connecting the center point of the first water nozzle end face and the center point of the second water nozzle end face and the intersection point is within a fourth preset range, such as about 1.7 mm, so as to ensure that the distance between the laser beam of the first photoelectric counter 1 and the center point of the first water nozzle end face is within the second preset range, and the distance between the laser beam of the second photoelectric counter 2 and the center point of the second water nozzle end face is within the third preset range.

[0031] In the embodiment of the present application, the first channel 55 and the second channel 56 are symmetrical about the symmetry axis of the body 5, in order to realize the intersection of the laser beam of the first photoelectric counter 1 and the laser beam of the second photoelectric counter 2, the first fixed seat 51 and the third fixed seat 53 are symmetrical about the symmetry axis of the body 5, and the second fixed seat 52 and the fourth fixed seat 54 are symmetrical about the symmetry axis of the body 5. The first fixed seat 51 is used to fix the emitting end or receiving end of the first photoelectric counter 1, the second fixed seat 52 is used to fix the receiving end or emitting end of the first photoelectric counter 1, the third fixed seat 53 is used to fix the emitting end or receiving end of the second photoelectric counter 2, and the fourth fixed seat 54 is used to fix the receiving end or emitting end of the second photoelectric counter 2.

[0032] Figure 5 is a top view of the body provided by the embodiment one of the present application. As shown in the figure, the first channel 55 and the second channel 56 are symmetrical about the symmetry axis of the body 5, and each is divided into two parts, and there is a bend at the joint of the two parts. The part close to the water nozzle is gathered towards the symmetry axis of the body 5, so that the distance between the center point of the first water nozzle end face and the center point of the second water nozzle end face is within a first preset range. Figure 5 Figure 7 is a schematic diagram of the angle relationship provided by the embodiment one of the present application. In combination with Figure 5 and Figure 7 , the perpendicular of the first water nozzle end face forms a second included angle with the symmetry axis of the body 5, and the perpendicular of the second water nozzle end face forms a fourth included angle with the symmetry axis of the body 5.

[0033] Figure 6 is still another top view of the detection device provided by the embodiment one of the present application. As shown in the figure, the first photoelectric opposite radiation tube 1 and the second photoelectric opposite radiation tube 2 are symmetrical about the symmetry axis of the body 5, and the laser beam of the first photoelectric opposite radiation tube 1 and the laser beam of the second photoelectric opposite radiation tube 2 intersect with each other. In combination with Figure 6 Figure 6 and Figure 7 , the laser beam of the first photoelectric opposite radiation tube 1 forms a first included angle with the symmetry axis of the body 5, and the laser beam of the second photoelectric opposite radiation tube 2 forms a third included angle with the symmetry axis of the body 5.

[0034] In order to ensure that the intersection point of the two laser beams is located on the perpendicular of the line connecting the first detection point 3 and the second detection point 4 and away from the animal, the distance between the line connecting the center point of the first water nozzle end face and the center point of the second water nozzle end face and the intersection point is within a fourth preset range. In the embodiment of the present application, under the condition of axial symmetry, the first included angle of the laser beam of the first photoelectric opposite radiation tube 1 with the symmetry axis of the body 5 is greater than the second included angle of the perpendicular of the first water nozzle end face with the symmetry axis of the body 5, and the sum of the first included angle and the second included angle is within a fifth preset range; the third included angle of the laser beam of the second photoelectric opposite radiation tube 2 with the symmetry axis of the body 5 is greater than the fourth included angle of the perpendicular of the second water nozzle end face with the symmetry axis of the body 5, and the sum of the third included angle and the fourth included angle is within the fifth preset range; the first included angle is equal to the third included angle, and the second included angle is equal to the fourth included angle. For example, the first included angle and the third included angle are 45.2 degrees, and the second included angle and the fourth included angle are 35.9 degrees. Figure 7 ​​The scenario shown is where the sum of the first and second included angles is 90 degrees, and the sum of the third and fourth included angles is also 90 degrees. In this case, the laser beam from the first photoelectric transmitter 1 is parallel to the end face of the first water nozzle, and the laser beam from the second photoelectric transmitter 2 is parallel to the end face of the second water nozzle. In practical applications, the laser beams and the end faces of the water nozzles may be slightly non-parallel, meaning the sum of the first and second included angles deviates from 90 degrees by a certain angle, such as within the range of 80-100 degrees (the fifth preset range includes 90 degrees). This ensures that the distance between the laser beam from the first photoelectric transmitter 1 and the center point of the end face of the first water nozzle is within the second preset range. Similarly, the sum of the third and fourth included angles deviates from 90 degrees by a certain angle.

[0035] Figure 8 This is a schematic diagram of the detection device provided in Embodiment 1 of the present invention. Figure 8 As shown, in order to make the plane formed by the intersection of the laser beam and the two water nozzles close to the horizontal plane, the laser beam forms an angle with the bottom surface of the body 5, such as 11 degrees.

[0036] Figure 9 This is a side view of the main body provided in Embodiment 1 of the present invention. Figure 9 As shown, the central axis of the two water spouts forms an angle with the bottom surface of the main body 5, such as 1 degree, so that the two water spouts are slightly upward, and the water droplets can be better hung at the water spouts, while conforming to the animal's licking action from bottom to top.

[0037] Figure 10 This is another schematic diagram of the main body provided in Embodiment 1 of the present invention. For example... Figure 10 As shown, the main body 5 also includes a third channel 57 for guiding gas. The outlet of the third channel 57 is higher than the first and second water nozzles. In animal behavior training related to smell and water supply, the outlet of the third channel 57 corresponds to the animal's nasal cavity, providing odor stimulation to the animal. The gas includes one or more different odors, such as octane, butanol, ethyl acetate, etc.

[0038] In this embodiment of the invention, the distance between the first detection point and the second detection point is within a small first preset range. The laser beams of the first photoelectric tube and the second photoelectric tube are used to detect whether the first detection point and the second detection point are touched, respectively, which avoids the microcurrent from entering the animal's body and improves the accuracy of animal behavior training.

[0039] Figure 11 This is a structural block diagram of the animal behavior training system provided in Embodiment 2 of the present invention. Figure 11 As shown, the animal behavior training system includes a controller, a water source, and a detection device described in Example 1. In this embodiment of the invention, the detection device is the same as in Example 1, including all the features described in Example 1, and will not be repeated here.

[0040] In the embodiment of the present application, the water source is guided to the first detection point 3 and the second detection point 4 through a pipeline, and the controller controls the on-off of the water source and detects whether the first detection point 3 and the second detection point 4 are touched or licked through the first photoelectric opposite radiation tube 1 and the second photoelectric opposite radiation tube 2.

[0041] Compared with one detection point, two detection points can provide more complex animal behavior training, but the increase of parts and the relationship between parts also put higher requirements on the overall integration of the detection device.

[0042] The distance between the first detection point and the second detection point in the embodiment of the present application is in a small first preset range, and whether the first detection point and the second detection point are touched is detected through the laser beams of the first photoelectric opposite radiation tube and the second photoelectric opposite radiation tube, so that the micro-current is prevented from entering the animal body, and the accuracy of animal behavior training is improved.

[0043] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limiting the present application, and those skilled in the art can make changes, modifications, replacements and variations to the above embodiments within the scope of the present application.
