Description

Technical Field

[0001] This utility model relates to the technical field of animal laboratory cage cleaning equipment, specifically an animal laboratory cage cleaning device. Background Technology

[0002] Animal laboratory cages are specialized equipment used in laboratories for raising and managing laboratory animals. They are typically made of materials such as stainless steel and plastic, and come in various types, including individually ventilated cages and metabolic cages. They provide a living environment for laboratory animals and protect the safety of personnel and the environment. Animal laboratory cage cleaning devices are specifically designed to clean these cages. Through high-pressure water jets, cleaning agents, and disinfectants, they effectively remove dirt, residues, and microorganisms, ensuring the cleanliness and sterility of the cages, thereby protecting the health of laboratory animals and the accuracy of experimental results.

[0003] For example, the automatic cleaning and treatment device for laboratory animal cages disclosed in Chinese patent literature (publication number: CN223070107U) uses several nozzles to clean the cages evenly from all directions; this cleaning device can clean the cages evenly and effectively, avoiding leaving a large amount of residue on the cages, and has a good cleaning effect while improving cleaning efficiency.

[0004] However, after the cages in this device are cleaned, the top cover must be opened to remove the cages, and then they must be transferred to a separate draining device for further processing. The cleaning and draining processes are sequentially connected. This process not only increases the number of manual transfer steps, but also limits the number of cages that can be processed per unit time due to the significant waiting gap between the two processes, resulting in low overall cleaning efficiency.

[0009] As a further embodiment of this utility model: the support assembly includes a support leg sleeve, a movable support leg, and a spring. The support leg sleeve is fixedly connected to the other end of the bottom of the multi-hole loading box. The movable support leg is vertically slidably connected to the inside of the support leg sleeve. The spring is fixedly connected to the top of the inside of the support leg sleeve, and the other end of the spring is fixedly connected to the top of the movable support leg. A base frame and rollers are also included. The base frame is fixedly connected to the bottom of the movable support leg, and the rollers are rotatably connected to the lower inner side of the base frame.

[0010] As a further embodiment of this utility model: the cleaning mechanism includes a cylinder, a telescopic folding tube, and a connecting diverter head.

After cleaning, the operation is reversed to send the cage to the higher draining position. Simultaneously, another loading mechanism prepares new cages, achieving simultaneous rinsing and draining without waiting or removing cages, significantly improving efficiency. Once the cage reaches the cleaning station, a liquid pump draws liquid from the cleaning liquid tank, which flows through a delivery pipe and a diversion component to a frame-shaped pipe. A cylinder drives the rinsing assembly to move up and down, rinsing the cage from all directions. The height can be adjusted to accommodate different cage sizes, improving cleaning effectiveness and versatility. Waste rinsing liquid flows into the bottom of the cleaning chamber through the holes in the loading box and the track grooves. After impurities are filtered by the filter cartridge, it is discharged from the outlet pipe. A retaining ring facilitates filter cartridge replacement, ensuring convenient waste liquid treatment.

The embodiments of this utility model will be described below based on its overall structure.

[0017] Reference Figures 1 to 6 In this embodiment of the utility model, an animal experimental cage cleaning device includes: a base frame 1 and a cleaning liquid tank 2. The base frame 1 serves as the overall support structure of the device, and the cleaning liquid tank 2 stores the cleaning liquid required for cleaning the cages. A cleaning chamber 3 is fixedly connected to the top of the base frame 1. The core working space is divided into a central low-level cleaning station and two high-level draining stations on both sides by a U-shaped structure, realizing the functional zoning of cleaning and draining, while collecting rinsing waste liquid and providing space for parallel operations.

[0018] The bottom of the cleaning chamber 3 is fixedly connected to a double track 4, which provides a sliding path for the movement of the vehicle. The cleaning chamber 3 has a loading mechanism 5 on both the inner and outer sides, which is responsible for loading, transporting and limiting the cage. A support frame 6 is fixedly connected above the base frame 1 and on the back of the cleaning chamber 3 to provide stable support.

[0019] A liquid pump 7 is fixedly connected to the front bottom of the cleaning liquid tank 2 via a pipe. The output end of the liquid pump 7 is fixedly connected to the cleaning liquid delivery pipe 8. The liquid pump 7 serves as the power source for the cleaning liquid delivery, drawing out the cleaning liquid from the cleaning liquid tank 2, pressurizing it, and delivering it to the cleaning liquid delivery pipe 8 to ensure the rinsing pressure. The front end of the support frame 6 and the cleaning liquid delivery pipe 8 are jointly provided with a cleaning mechanism 9, which is responsible for the all-round rinsing of the cage. The bottom surface of the cleaning chamber 3 and the double track 4 are both U-shaped structures, and the connection between the high and low positions of the cleaning chamber 3 and the double track 4 is inclined. There are two sets of double track 4. The bottom surface of the middle section of the double track 4 is provided with a through groove for liquid flow. The cleaning liquid delivery pipe 8 is fixedly connected to the support frame 6.

[0020] Reference Figure 2 The inner middle of the cleaning chamber 3 is located at the liquid outlet. The inner ring of the retaining ring 10 is fixedly connected to the filter cartridge 11. The bottom middle of the cleaning chamber 3 is fixedly connected to the liquid outlet pipe 12. After the waste liquid is collected at the bottom of the cleaning chamber 3, it flows through the filter cartridge 11. Impurities are intercepted by the filter cartridge. The filtered waste liquid is discharged from the cleaning chamber through the liquid outlet pipe 12, realizing centralized treatment of waste liquid. The retaining ring 10 facilitates the replacement of the filter cartridge 11.

[0021] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 The loading mechanism 5 includes a perforated loading box 51, a limiting block 52, and a support assembly 53. The limiting block 52 is fixedly connected to one bottom end of the perforated loading box 51, and the support assembly 53 is provided in multiple sets, symmetrically arranged at the bottom of the perforated loading box 51. The system comprises a motor 54, a shaft 55, and a rotating stop 56. The motor 54 is fixedly connected to one end of the outer side of the cleaning chamber 3. The shaft 55 is fixedly connected to the output end of the motor 54 and rotatably connected to the cleaning chamber 3, with a portion extending into the interior of the cleaning chamber 3. The rotating stop 56 is fixedly connected to the end of the shaft 55 extending into the cleaning chamber 3. The animal experimental cages to be cleaned are placed on the porous loading box 51, whose porous structure allows for penetrating cleaning with the cleaning solution. The motor 54 is started, and its output end drives the shaft 55 to rotate, causing the rotating stop 56 on the shaft 55 to rotate accordingly. When the limiting block 52 at the bottom of the perforated loading box is blocked, the limiting of the perforated loading box 51 is released, allowing the perforated loading box 51 containing the cage to be cleaned to move along the double track 4 via the support assembly 53 until the cage is transported to the cleaning station in the lower middle part of the cleaning chamber 3. After cleaning, the operation is reversed, pushing the perforated loading box 51 containing the cleaned cage along the double track 4 towards the higher part of the cleaning chamber 3. The motor 54 drives the shaft 55 to rotate, causing the rotating stop 56 on the shaft 55 to come into contact with the rotating stop 56, thereby limiting the movement and performing the draining operation.

[0022] Reference Figure 4 and Figure 5 The support assembly 53 includes a support leg sleeve 531, a movable support leg 532, and a spring 533. The support leg sleeve 531 is fixedly connected to the other end of the bottom of the multi-hole loading box 51. The movable support leg 532 is vertically slidably connected to the inside of the support leg sleeve 531. The spring 533 is fixedly connected to the top end of the inside of the support leg sleeve 531. The other end of the spring 533 is fixedly connected to the top of the movable support leg 532. The base frame 534 is fixedly connected to the bottom of the movable support leg 532, and the roller 535 is rotatably connected to the lower inner side of the base frame 534. The perforated loading box 51, which contains the cage to be cleaned, moves along the double track 4 via the roller 535. During the sliding process, the spring 533 in the support assembly 53 can elastically extend and retract, which, together with the vertical sliding of the movable support leg 532 in the support leg sleeve 531, adapts to the height changes of the U-shaped structure and inclined connection part of the double track 4 and the cleaning chamber 3, ensuring that the perforated loading box 51 smoothly transports the cage to the cleaning station in the lower middle part of the cleaning chamber 3.

[0023] Reference Figure 1 , Figure 3 and Figure 6 The cleaning mechanism 9 includes a cylinder 91, a telescopic folding tube 92, and a connecting diverter head 93. The cylinder 91 is symmetrically fixedly connected to the front two sides above the support frame 6. The telescopic folding tube 92 is fixedly connected to the pipe opening above the cleaning fluid delivery pipe 8. The connecting diverter head 93 is fixedly connected to the bottom of the telescopic folding tube 92. The branch pipes 94 and the connecting brackets 95 are provided in multiple sets and are symmetrically fixedly connected to the outside of the connecting head 93. The connecting brackets 95 are fixedly connected to the top of the multiple sets of branch pipes 94. The movable end of the cylinder 91 is fixedly connected to the connecting brackets 95. The frame tube 96 and nozzles 97 are fixedly connected to the bottom of the multi-group branch pipes 94. Multiple sets of nozzles 97 are symmetrically fixed to the inside of the frame tube 96. When the cage reaches the cleaning station in the lower middle part of the cleaning chamber 3, the liquid pump 7 is started to extract the cleaning liquid in the cleaning liquid tank 2 and transport it through the pipeline to the cleaning liquid delivery pipe 8. The cleaning liquid enters the connecting diverter head 93 through the telescopic folding pipe 92, and then the connecting diverter head 93 distributes the cleaning liquid to multiple branch pipes 94, and finally delivers it to the frame tube 96. At the same time, the movable end of the cylinder 91 pushes the connecting frame 95, which drives the connecting diverter head 93, branch pipes 94, frame tube 96 and other components to move downward to form a full-range rinsing range, thoroughly rinsing all surfaces of the cage and improving the cleaning effect. The cylinder 91 can adjust the rinsing height to adapt to different sizes of animal experimental cages and improve the versatility of the device.

[0024] The working principle of this utility model is as follows: During use, the animal experimental cages to be cleaned are placed on the porous loading box 51. Its porous structure allows for the penetration and cleaning of the cleaning solution. The motor 54 is started, and its output drives the shaft 55 to rotate. The rotating stop 56 on the shaft 55 rotates accordingly, contacting the limiting block 52 at the bottom of the porous loading box, thus releasing the limitation of the porous loading box 51. This allows the porous loading box 51, containing the cages to be cleaned, to move along the double track 4 via the rollers 535. During sliding, the spring 533 in the support assembly 53 can elastically extend and retract, cooperating with the vertical sliding of the movable support leg 532 within the support leg sleeve 531. This adapts to the height changes of the concave structure and inclined connection of the double track 4 and the cleaning chamber 3, ensuring that the porous loading box 51 smoothly transports the cages to the lower center of the cleaning chamber 3. After cleaning, the cleaning station reverses the operation, pushing the perforated loading box 51 containing the cleaned cages along the double track 4 via rollers 535 towards a higher position on one side of the cleaning chamber 3. The motor 54 drives the shaft 55 to rotate, causing the rotating stop 56 on the shaft 55 to come into contact with the rotating stop 56, thereby limiting the position and performing the draining operation. At this time, the cages can be loaded through another loading mechanism 5 to perform the above operation. In this way, the cages in the cleaning station can be rinsed while the cleaned cages are drained in the draining station. By dividing the cleaning and draining into two independent functional areas, and with the alternating use of two loading mechanisms 5, the two processes can be carried out in the same space without having to take out the washed cages or wait for them to drain. This achieves simultaneous operation of rinsing and draining, greatly improving cleaning efficiency. When the cage reaches the cleaning station at the lower part of the middle of the cleaning chamber 3, the liquid pump 7 starts, extracting the cleaning liquid from the cleaning liquid tank 2 and transporting it through the pipeline to the cleaning liquid delivery pipe 8. The cleaning liquid enters the connecting diverter head 93 through the telescopic folding pipe 92, and then the connecting diverter head 93 distributes the cleaning liquid to multiple diverter branches 94, and finally delivers it to the frame pipe 96. At the same time, the movable end of the cylinder 91 pushes the connecting frame 95, causing the connecting diverter head 93, diverter branches 94, frame pipe 96 and other components to move downward, forming a full-range rinsing range to thoroughly rinse all surfaces of the cage, improving the cleaning effect. In addition, the cylinder 91 can adjust the rinsing height to adapt to different sizes of animal experimental cages, improving the versatility of the device. During the rinsing process, waste liquid containing impurities such as animal feces and food residue flows into the bottom of the cleaning chamber 3 through the holes of the porous loading box 51. The through groove in the middle section of the double track bar 4 avoids obstructing the water flow. After the waste liquid collects at the bottom of the cleaning chamber 3, it flows through the filter cartridge 11. The impurities are intercepted by the filter cartridge, and the filtered waste liquid is discharged from the cleaning chamber through the outlet pipe 12, realizing centralized treatment of waste liquid. The filter cartridge 11 is easy to replace through the setting of the retaining ring 10.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
