[0002] In the field of life science research, the physiological stability of laboratory mice directly determines the reliability and reproducibility of research data. Feed, as a core factor affecting mouse health, must meet stringent experimental standards regarding its mixing uniformity and hygiene safety. Currently, laboratory mouse feed often requires the addition of vitamins, drugs, or special nutrients based on research needs. This necessitates mixing equipment that can achieve efficient and uniform mixing of materials, prevent cross-contamination between different batches of feed, and meet the requirements for frequent cleaning and disinfection.

[0003] Traditional mixing equipment often uses welded blades to connect to the main shaft. When processing sticky feeds containing moisture or oil, residue easily adheres to the blade roots, corners of the mixing chamber, and gaps in the transmission components. To achieve thorough cleaning, existing equipment often requires manual disassembly of the mixing components. This cumbersome process not only increases the workload of experimental personnel but also leads to a decrease in equipment utilization due to the excessively long cleaning cycle, making it difficult to meet the continuous needs of multiple batches of experiments.

[0004] Therefore, it is necessary to invent a mouse feed mixing device that is easy to disassemble and clean to solve the above problems. Utility Model Content

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] This utility model provides, for example Figure 1-6 The mouse feed mixing device shown is easy to disassemble and clean. It includes a mixing cylinder 1, a cover 2 on the top of the mixing cylinder 1, and a discharge hopper 3 connected to the bottom. The top and bottom of the mixing cylinder 1 are provided with fixing components 4 that connect the cover 2 and the discharge hopper 3. A mixing motor 5 is installed at the center of the top of the cover 2. A mixing rod 6 is connected to the bottom of the mixing motor 5. A feed hopper 7 is installed on one side of the mixing motor 5. Specifically, the fixing component 4 includes multiple fixing blocks 41 fixed on the upper and lower sides of the outer wall of the mixing cylinder 1. The bottom of the multiple fixing blocks 41 is provided with a telescopic groove 42. A locking block 43 is installed in the telescopic groove 42. The bottom of the telescopic groove 42 is provided with a through hole 44. One end of the locking block 43 is provided with a connecting rod 45 that matches the through hole 44. A ball 46 is fixed at the end of the connecting rod 45. The upper and lower locking blocks 43 are respectively fixed to the top of the cover 2 and the edge of the discharge hopper 3.

[0018] Specifically, a limiting frame 47 is provided at the opening of the telescopic groove 42, and a limiting strip 48 matching the limiting frame 47 is provided at the end of the locking block 43. A compression spring 49 is provided between the bottom of the telescopic groove 42 and the end of the locking block 43. The compression spring 49 is located outside the connecting rod 45. The locking block 43 extends and retracts within the telescopic groove 42, and one side of the bottom of the locking block 43 is set as an inclined surface. The overall length of the locking block 43 matches the depth of the telescopic groove 42, and the size of the ball 46 is larger than the size of the through hole 44.

[0019] Specifically, the fixing block 41 is L-shaped, and the size of the compression spring 49 is larger than the size of the through hole 44.

[0020] Specifically, the top center of the cover 2 is provided with an installation groove 21, in which a stirring motor 5 is installed. The bottom of the stirring motor 5 is fixed in the installation groove 21 by bolts 51. On one side of the installation groove 21, there is an inlet installation groove 22 for installing a feeding hopper 7. The top dimension of the feeding hopper 7 is larger than the bottom dimension.

[0021] Specifically, the stirring rod 6 is connected to the bottom of the stirring motor 5, and the bottom of the stirring rod 6 is connected to the inner wall of the stirring cylinder 1. The upper and lower sides of the outer wall of the stirring cylinder 1 are provided with sealing rings 11, and the cover 2 and the discharge hopper 3 are matched and installed on the outside of the sealing rings 11.

[0022] Specifically, the bottom of the discharge hopper 3 is provided with a discharge pipe 31, and a rotating hole 32 is provided on one side of the discharge pipe 31. A discharge valve 33 is installed in the rotating hole 32.

[0023] In this embodiment, the cover 2 is aligned with the top of the mixing cylinder 1, and the edge of the cover 2 contacts the inclined surface of the locking block 43; the cover 2 is pressed down, and the inclined surface is pushed to retract the locking block 43 inward along the telescopic groove 42, and the compression spring 49 is compressed; when the cover 2 is completely in contact with the sealing ring 11 at the top of the mixing cylinder 1, the locking block 43 is reset under the elastic force of the compression spring 49 and embedded in the slot at the top of the cover 2. At the same time, the limiting strip 48 is inserted into the limiting frame 47 at the opening of the telescopic groove 42 to prevent the locking block 43 from falling off, thus completing the fixing of the cover 2.

[0024] Specifically, upon inspection of the top of the cover 2, the stirring motor 5 in the mounting groove 21 is fixed by bolts 51, the feed hopper 7 in the feeding mounting groove 22 is installed in place, and the bottom of the stirring rod 6 is connected to the bearing pre-set on the inner wall of the stirring cylinder 1 to ensure that the stirring rod 6 can rotate flexibly.

[0025] In this embodiment, referring to the assembly logic of the cover 2, the discharge hopper 3 is aligned with the bottom of the mixing drum 1, and the edge of the discharge hopper 3 contacts the inclined surface of the lower locking block 43; the discharge hopper 3 is pushed upward, and the locking block 43 retracts and resets, embedding into the groove on the edge of the discharge hopper 3. The limiting strip 48 and the limiting frame 47 cooperate to limit the movement, and at the same time, the inner wall of the discharge hopper 3 is in contact with the sealing ring 11 at the bottom of the mixing drum 1, achieving sealing and fixation. Check the bottom of the discharge hopper 3: the discharge pipe 31 is unobstructed, and the discharge valve 33 in the rotating hole 32 is in the closed state.

[0026] In this embodiment, the mixing operation involves pouring mouse feed into the feed hopper 7 through the top opening. The feed naturally slides down the conical structure of the feed hopper 7 and enters the mixing cylinder 1 through the bottom outlet, preventing feed from adhering to the inner wall of the feed hopper and causing waste. When the power to the mixing motor 5 is turned on, the motor output shaft drives the mixing rod 6 to rotate. As the mixing rod 6 rotates inside the mixing cylinder 1, it pushes the feed up and down, ensuring that the feed in different locations inside the cylinder is evenly mixed. The mixing time is set according to the total amount of feed.

[0027] In this embodiment, after mixing is completed, the discharge valve 33 at the bottom of the discharge hopper 3 is manually rotated: the valve rod rotates along the rotating hole 32, and the contact state between it and the inner wall of the discharge pipe 31 is released, forming a discharge channel; the mouse feed slides down the conical inner wall of the discharge hopper 3 under the action of gravity to the discharge pipe 31 and flows out from the pipe opening; according to the feeding requirements, the discharge speed is controlled by adjusting the rotation angle of the valve 33 to avoid feed spillage.

[0028] In this embodiment, the power supply to the stirring motor 5 is disconnected before cleaning. For the cover 2: manually pull the ball 46 inside the bottom through hole 44 of the fixing block 41, the connecting rod 45 drives the locking block 43 to compress the spring 49, so that the locking block 43 exits the slot of the cover 2; lift the cover 2 upwards, and simultaneously separate the bearing between the bottom of the stirring rod 6 and the inner wall of the cylinder 1, completing the overall disassembly of the cover, stirring motor, stirring rod, and feed hopper. For the discharge hopper 3: similarly pull the lower ball 46, so that the locking block 43 exits the slot of the discharge hopper 3, and remove the discharge hopper 3 downwards.

[0029] In this embodiment, the mixing cylinder 1, cover 2, mixing rod 6, feed hopper 7, and discharge hopper 3 are cleaned respectively. They can be rinsed with clean water or cleaned with a soft brush. Since each part is detachable, there are no dead corners for cleaning, thus avoiding the growth of bacteria from feed residue.

[0030] In this embodiment, the fixing component 4 can be assembled and disassembled manually without the aid of tools, and the operation time for a single person is no more than 2 minutes. Compared with traditional bolt-connected equipment, the efficiency is improved by more than 60%, which is especially suitable for the needs of frequent cleaning in the laboratory. Specifically, the bottom of the stirring rod 6 is connected to the bearing on the inner wall of the stirring cylinder 1 to ensure stable rotation without shaking; during the stirring process, the feed forms an up-and-down circulation inside the cylinder to avoid local feed accumulation. After testing, the uniformity of the mixed mouse feed reached more than 95%, which meets the requirements of balanced nutrition for mouse breeding.

[0031] In this embodiment, each component is detachable and separable, with no hidden gaps, allowing direct contact with all surfaces during cleaning to effectively remove feed residue; the sealing ring 11 is made of food-grade silicone, which is odorless and does not breed mold after cleaning; the stirring motor 5 is fixed by bolts 51, and there is no need to contact the inside of the motor during disassembly, resulting in a high level of operational safety.

[0032] The above description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
