Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] See Figures 1 to 4This invention provides an animal weighing bowl 10, which works in conjunction with an external weighing component 600 for use in laboratories to detect weight changes in animals such as mice and rabbits. The animal weighing bowl 10 can automatically identify animals using RFID (Radio Frequency Identification) tags, quickly and automatically recording experimental information such as the species and number of the animal to be weighed. This improves the detection and recording of animal information changes by laboratory personnel, reduces experimental errors, and facilitates analysis and long-term management.

[0034] Furthermore, the animal weighing bowl 10 includes a support component 100, an RFID detection module 200, a control module 300, and a posture detection device 400. The support component 100 is used to carry the animal to be inspected, and it includes an inner shell 110 and an outer shell 120 nested together. The inner shell 110 has a receiving cavity 111 for accommodating the animal, and the outer shell 120 has an installation cavity 130 between it and the inner shell 110. The RFID detection module 200 is built into the support component 100. The RFID detection module 200 can read the RFID tag information of the animal within a certain range through short-range wireless communication technology. The posture detection device 400... The measuring device 400 is installed on the control module 300. The posture detection device 400 is used to detect the vertical state of the inner shell 110 and the outer shell 120. The control module 300 is connected to the RFID detection module 200 and the posture detection device 400 for data transmission. The control module 300 can receive and process the information data from the RFID detection module 200 and the posture detection device 400. The control module 300 also transmits the detected animal information to external devices, such as computers, thereby realizing automatic recording of the entire process, greatly reducing the errors caused by manual detection and recording during the experiment, and improving detection efficiency and analysis accuracy. It should be noted that in this embodiment, the control module 300 is a PCBA, which is fixed in the mounting cavity 130. The control module 300, the RFID detection module 200, and the posture detection device 400 can be wirelessly or wiredly connected, or the RFID detection module 200 can be embedded in the control module 300. The animal weighing bowl 10 also includes a power supply component, which is fixed in the mounting cavity 130 and supplies power to the control module 300.

[0035] In this embodiment, the attitude detection device 400 is integrated into the control module 300. The attitude detection device 400 can employ a gyroscope sensor, accelerometer, or liquid level, etc., and its specific structure is not limited, as long as it can detect the attitude of the supporting component 100. The control module 300 is fixed in the mounting cavity 130 by a fixing rod. The attitude detection device 400 can detect the attitude of the inner shell 110 and the outer shell 120. Specifically, the attitude detection device 400 includes three detection states: the first is the upright state, in which all modules enter the correct working state, and the weighing data is recorded to the control module 300; the second is the tilted state, in which the experimenter is alerted that the supporting component 100 is unstable; and the third is the inverted state, in which the control module 300 controls the shutdown of all modules and enters the shutdown mode. It can be understood that by setting up the attitude detection device 400, it is possible to ensure that the animal weighing bowl can be started or stopped without setting up a physical button. In the laboratory, mice are generally kept in an environment free from external pollution to prevent external factors from affecting the experimental results. Controlling the start and stop of the load-bearing assembly 100 by flipping it can reduce contact contamination of the animal weighing bowl and reduce cleaning costs. Furthermore, the bottom of the inner shell 110 is provided with an arc surface 112 that connects circumferentially. In this embodiment, the bottom wall edge of the inner shell 110 is provided with an arc surface 112 that surrounds circumferentially, and the arc surface 112 transitions between the side surface and the bottom surface of the inner shell 110, specifically, the arc surface 112 is chamfered. When the animal enters the receiving cavity 111, due to the presence of the arc surface 112, the animal will slide from the edge of the receiving cavity 111 to the middle position of the receiving cavity 111, thereby reducing the risk of the animal hitting the side wall of the inner shell 110 and causing the entire load-bearing assembly 100 to tip over. It is understandable that the curved surface 112 can also be replaced by an inclined surface, for example, the inclined surface is connected to the side and bottom surfaces of the receiving cavity 111 respectively, so that the lower half of the receiving cavity 111 is funnel-shaped.

[0036] Further, refer to Figure 2The opening edges of the inner shell 110 and the outer shell 120 are connected, and the RFID detection module 200 is fixedly positioned around the opening edges of the inner shell 110 and the outer shell 120. In this embodiment, both the openings of the inner shell 110 and the outer shell 120 are circular. The RFID detection module 200 is positioned at the opening edges of the inner shell 110 and the outer shell 120, allowing the RFID detection module 200 to quickly read and identify animal information when an animal enters the opening of the receiving cavity 111. The RFID detection module 200 is circularly positioned around the opening of the receiving cavity 111, allowing for rapid reading and identification when an animal enters the receiving cavity 111 from any direction. It should be noted that the RFID detection modules 200 can also be spaced apart at the opening for multi-directional reading. The RFID detection module 200 is wirelessly connected to the control module 300. After identifying information such as the animal's species and number, it quickly transmits the information to the control module 300, which then categorizes the information and simultaneously sends it to external devices.

[0037] Further, referring to Figure 4, the mounting cavity 130 is a U-shaped cavity, with the outer sidewall of the inner shell 110 and the inner sidewall of the outer shell 120 spaced apart, and a gap space formed between the bottom of the inner shell 110 and the bottom wall of the outer shell 120. In this embodiment, the inner shell 110 has an approximately cylindrical structure, with the sidewall of the inner shell 110 forming an angle with the axis of the inner shell 110, and the diameter of the inner shell 110 gradually decreasing from top to bottom in the vertical direction. A gap is formed between the sidewall of the inner shell 110 and the sidewall of the outer shell 120, and a gap space is formed between the bottom of the inner shell 110 and the bottom of the outer shell 120. This gap space is part of the mounting cavity 130, and the control module 300 and the attitude detection device 400 are disposed within this gap space.

[0038] It should be noted that in the first embodiment, the animal weighing bowl 10 does not include the weighing component 600. The weighing component 600 is used in combination with the animal weighing bowl 10 as an external device. During weighing, the bottom of the outer shell 120 is placed on the external weighing component 600 to perform the weighing. This allows the animal weighing bowl 10 to be used with different types of weighing components 600, making it suitable for different weighing components 600 and improving its applicability.

[0039] Further, refer to Figure 3 and Figure 4 The bottom of the outer casing 120 has a fixing cavity 122, which is used to snap onto the external support surface. In this embodiment, the bottom of the outer casing is mounted on the external weighing assembly 600 for weighing. The upper surface of the weighing assembly 600 can be provided with a locking block that snaps into the fixing cavity 122. When the outer casing is placed on the weighing assembly 600, the locking block snaps into the fixing cavity 122, thereby making the outer casing 120 and the weighing assembly 600 stably connected.

[0040] Further, refer to Figure 3 and Figure 4 A support member 121 is fixedly installed at the bottom of the fixed cavity 122. The support member 121 is used to abut against the external support surface to support the outer shell 120. The support member 121 is integrally connected and fixed to the bottom surface of the fixed cavity 122. The support member 121 is used to improve the stability of the outer shell 120 to prevent the outer shell 120 from tipping over due to animal activity. It should be noted that the support member 121 can also serve as an auxiliary support. For example, if the main support part of the outer shell 120 is the bottom, the support member 121 can be multiple inclined support rods set at the bottom edge. The support rods are inclined away from the center of the bottom surface, thereby increasing the overall support area of ​​the outer shell 120 and improving stability.

[0041] Furthermore, the support member 121 comprises multiple spherical protrusions. In this embodiment, the spherical protrusions are hemispherical structures, and multiple spherical protrusions are located on the bottom surface of the outer shell 120 and arranged at relative intervals. It can be understood that there are no fewer than two spherical protrusions, so that each spherical protrusion serves as a fulcrum, improving stability. The spherical protrusions are fixed within the fixing cavity 122. In this embodiment, a portion of the structure of the spherical protrusion is built into the fixing cavity 122 and fixedly connected to the bottom wall of the fixing cavity 122. The upper surface of the corresponding weighing component 600 is also provided with a groove for the spherical protrusion to be inserted into. A portion of the structure of the spherical protrusion extends out of the fixing cavity 122 to be inserted into the aforementioned groove. It can be understood that the space of the fixing cavity 122 can be used to avoid debris on the external support surface, ensuring that the entire weighing device is not affected and reducing weighing errors. The side walls of the fixing cavity 122 can also provide support, further improving the stability of the device. In addition, the side walls of the fixing cavity 122 can cover part of the support member 121, making its appearance cleaner. It should be noted that the spherical protrusion of the support member 121 can avoid stress concentration, has stronger compressive strength, and the arc-shaped surface can absorb some vibration energy to provide a partial cushioning effect. It can be understood that the support member 121 can also be set as a square protrusion.

[0042] Furthermore, a buzzer 500 connected to the control module 300 is installed inside the mounting cavity 130. The control module 300 controls the buzzer 500 to turn on or off based on the detection results of the attitude detection device 400. In this embodiment, the buzzer 500 can be a passive electromagnetic buzzer 500. The buzzer 500 is installed in the mounting cavity 130 and passes through the side wall of the mounting cavity 130. The sound hole of the buzzer 500 extends out of the outer side of the outer shell 120. Specifically, when the RFID detection module 200 fails to read the animal's RFID tag information or the posture detection device 400 detects a tilted state, the control module 300 activates the buzzer 500, which emits continuous short beeps. When the posture detection device 400 detects an upright state, the control module 300 activates the buzzer 500, which emits a long and a short beep to indicate that the detection is correct and the detection process begins. When the posture detection device 400 detects that the supporting component 100 is inverted, the control module 300 shuts everything down, and the posture detection device 400 enters a low-power state. It can be understood that the buzzer 500 is used to alert the experimenter to changes in the state of the animal weighing bowl 10 and to identify detection problems.

[0043] Furthermore, the animal weighing bowl 10 also includes a USB radio frequency (RF) transmitter. The control module 300 connects to the USB RF transmitter and transmits detection information. In this embodiment, the USB RF transmitter can connect to a computer via a USB interface. Specifically, the USB RF transmitter has a built-in 2.4GHz RF receiver chip and a USB-to-serial chip. The control module 300 can establish a wireless connection with the USB RF transmitter and package and send the RFID animal tag information data to the USB RF transmitter. After receiving the data, the USB RF transmitter uploads it to the computer for analysis and processing by researchers. It should be noted that the control module 300 can also connect directly to the computer via a built-in Bluetooth module to establish a data transmission channel through Bluetooth wireless communication.

[0044] Further, refer to Figure 5 In the second embodiment, the animal weighing bowl further includes a weighing component 600, with the bottom of the outer shell placed on the weighing component 600. The weighing component 600 is used to detect the weight of the animal in the containment cavity. In this embodiment, the supporting component, RFID detection module, control module, and posture detection device are all the same as in the first embodiment described above. The specific details of the weighing component 600 in this embodiment are also the same as the structure of the external weighing component 600 described above, and will not be described in detail here.

[0045] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
