Abstract
Description
Technical Field
[0001] This utility model relates to the field of food testing technology, and in particular to a portable egg-beating device for food sampling. Background Technology
[0002] Food safety inspection indicators mainly include general component analysis, trace element analysis, pesticide residue analysis, veterinary drug residue analysis, mycotoxin analysis, food additive analysis, and analysis of other harmful substances. Depending on the characteristics of the tested items, each indicator corresponds to a specific testing method. Sampling kits are typically used during food safety supervision and random inspections.
[0003] In sampling at egg-laying hen farms, multiple eggs need to be cracked into a container and thoroughly mixed before being dispensed into sampling bottles to prepare the samples. In current practice, due to the environmental conditions of the farms, it is inconvenient to clean conventional containers. Existing technologies mostly use disposable sealed bags as an alternative, cracking the eggs directly into the bag, mixing them by hand, and then transferring them to sampling bottles. However, manual egg cracking and mixing are inefficient, especially when processing a large number of samples, making it difficult to meet the sampling schedule requirements. While electric egg beaters commonly found on the market can improve mixing efficiency, their design is based on reusable scenarios, requiring thorough cleaning of the mixing head after each use, otherwise cross-contamination of the samples may occur.

A drive assembly is fixedly installed on the top of the fixed plate base. The drive assembly includes a rotating motor and a rotating rod. The rotating motor is fixedly installed on the top of the fixed plate base, and a rotating seat is fixedly installed on the drive end of the rotating motor. The rotating rod is fixedly installed inside the rotating seat. A cross-shaped protrusion is fixedly installed at the bottom of the rotating rod. A wedge block is fixedly installed at the top of the cross-shaped protrusion. A positioning pin is fixedly installed at the middle of the bottom end of the cross-shaped protrusion. The rotating rod, the cross-shaped protrusion, the wedge block, the wedge block, and the positioning pin are integrally formed. A stirring head assembly is detachably installed on the outside of the bottom of the rotating rod. The stirring head assembly includes a cylinder and a stirring paddle. A limiting groove matching the bottom of the rotating rod is opened inside the cylinder. The stirring paddle is threaded onto the bottom of the cylinder. A liquid collection tank is placed at the bottom of the fixed plate base, and the stirring head assembly is inserted into the liquid collection tank.
[0005] As an improvement to the above technical solution, the bottom of the insert is fixedly provided with an external thread, and the middle of the stirring paddle is provided with an internal thread, and the internal thread and the external thread can be detachably installed.
[0006] As an improvement to the above technical solution, the drive assembly includes a mounting box and an L-shaped mounting base. A tripod seat is bolted to the side wall of the mounting box and the top wall of the limiting groove. The L-shaped mounting base is bolted to the inner wall of the mounting box. The rotating motor is wired to a speed regulating seat and a switch button. Both the speed regulating seat and the switch button are embedded in the outer wall of the mounting box.
[0007] As an improvement to the above technical solution, a limiting groove is provided on the bottom upper surface of the fixed plate base, and the liquid collection tank can be placed inside the limiting groove.
[0008] As an improvement to the above technical solution, the rotating rod, cross protrusion, inclined block, wedge block, insert, stirring paddle and liquid collection tank are all made of plastic.

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.
[0013] Please see Figure 1-4 This utility model provides a technical solution: A portable egg-beating device for food sampling includes a fixed plate base 1. A drive assembly 2 is fixedly installed on the top of the fixed plate base 1. The drive assembly 2 includes a rotating motor 23 and a rotating rod 24. The rotating motor 23 is fixedly installed on the top of the fixed plate base 1. A rotating seat 231 is fixedly installed on the drive end of the rotating motor 23. The rotating rod 24 is fixedly installed inside the rotating seat 231. A cross-shaped protrusion 241 is fixedly installed on the bottom of the rotating rod 24. A wedge block 242 is fixedly installed on the top of the cross-shaped protrusion 241. A wedge-shaped locking block 24 is fixedly installed on the bottom of the cross-shaped protrusion 241. 3. A positioning pin 244 is fixedly installed at the middle of the bottom end of the cross-shaped protrusion 241. The rotating rod 24 is integrally formed with the cross-shaped protrusion 241, the inclined block 242, the wedge block 243 and the positioning pin 244. A stirring head assembly 3 is detachably installed on the bottom of the rotating rod 24. The stirring head assembly 3 includes a tube 31 and a stirring paddle 32. The inside of the tube 31 is provided with a limiting groove 311 that matches the bottom of the rotating rod 24. The stirring paddle 32 is threadedly installed on the bottom of the tube 31. A liquid collection tank 4 is placed at the bottom of the fixed plate base 1. The stirring head assembly 3 is inserted and installed inside the liquid collection tank 4.
[0014] In this embodiment, the fixed plate base 1 serves as the base of the device, providing a stable support platform to ensure the relative positions of the drive assembly 2, the stirring head assembly 3, and the collection tank 4 are fixed, preventing sample splashing or equipment damage due to shaking during operation. The rotating motor 23 of the drive assembly 2 is the core power source, driving the rotating seat 231 to rotate via electrical energy, providing continuous power for stirring. The rotating rod 24 connects the motor and the stirring head assembly 3, transmitting rotational power. Its bottom integrates a cross-shaped protrusion 241, an inclined block 242, a wedge-shaped locking block 243, and a positioning pin 244, forming a quick-assembly and disassembly structure. The rotating rod 24 and the bottom cross-shaped protrusion 241 are integrally formed. To enhance mechanical strength and prevent loosening or breakage after long-term use, the insert 31 of the stirring head assembly 3 has a limiting groove 311 inside, which matches the cross protrusion 241 at the bottom of the rotating rod 24, etc., to achieve quick positioning and locking. The stirring paddle 32 is threadedly installed at the bottom of the insert 31, directly contacting the egg liquid, and achieves uniform stirring through rotation. The detachable design makes it easy to replace different specifications of paddle blades, such as double spiral and single spiral, to adapt to different sample volume requirements. The collection tank 4 serves as a disposable stirring container to receive the beaten eggs and the stirred egg liquid. The flat bottom design facilitates dispensing into sampling bottles. Food-grade plastic meets food safety standards and avoids sample contamination.
[0015] Workflow: Align the limiting groove 311 of the insert 31 with the cross protrusion 241 at the bottom of the rotating rod 24, press down to engage the wedge block 243 with the inner wall of the insert 31, and simultaneously insert the positioning pin 244 into the positioning hole at the bottom of the insert 31 to complete the quick locking of the stirring head assembly 3 and the drive assembly 2. Place the collection bucket 4 at the designated position at the bottom of the fixed plate base 1, ensuring that the stirring paddle 32 is completely immersed in the bucket to prevent egg liquid from splashing out during stirring. Remove the lid 4 of the collection bucket and crack 3-5 eggs directly. Place the mixture into the container, start the rotating motor 23, and drive the rotating rod 24 and the stirring paddle 32 to rotate at a high speed of 500-1500 rpm (adjustable). The egg mixture will be fully mixed within 10-15 seconds. Turn off the motor, pull the stirring head assembly 3 off the rotating rod 24, and pour the mixture directly from the collection container 4 or use a sampling tube to draw the egg mixture into sampling bottles. If you need to process the next set of samples, you only need to replace the stirring head assembly 3. There is no need to clean the collection container 4 or the drive assembly 2. The preparation is completed within 30 seconds.
[0016] Results: By replacing manual stirring with electric drive, the sample preparation time for a single sample is reduced from 2 minutes to 30 seconds, and the processing time for 50 samples is reduced from 2 hours to 25 minutes, meeting the requirements of large-scale sampling. The stirring head assembly 3 is disposable and can be quickly replaced. It is discarded after each use to avoid contamination of subsequent samples by residual egg liquid. Aseptic operation is required. The mechanical locking of the cross-shaped protrusion 241 and the wedge-shaped locking block 243 allows the stirring head assembly to be installed or disassembled by one hand within 3 seconds. The stirring head assembly 3 is made of disposable plastic material, resulting in a low unit cost. This device is not only suitable for sampling in egg-laying chicken farms, but can also be extended to the homogenization of dairy products such as milk and yogurt; pretreatment of liquid food such as juice and honey for microbial detection; and rapid mixing of small laboratory samples.
[0017] Specifically, the bottom of the insert 31 is fixedly provided with an external thread 312, and the middle of the stirring paddle 32 is provided with an internal thread 321. The internal thread 321 and the external thread 312 can be detached and installed.
[0018] In this embodiment, the threaded connection achieves a tight fit between components through mechanical engagement, which is far more stable than simple connection methods such as snaps and pins. In the mixing equipment, the threaded fit between the insert 31 and the mixing paddle 32 needs to withstand the centrifugal force, fluid impact force and vibration load generated during the mixing process. The precise fit between the external thread 312 and the internal thread 321 can effectively disperse stress, prevent the connection from loosening or falling off, and ensure that the mixing paddle 32 maintains stable operation when rotating at high speed. For example, in the feed additive dispensing device, a similar thread design is used to connect the can lid and the mixing tank. Through the engagement of the external thread 312 and the internal thread 321, the can lid can be disassembled and sealed, providing a basic guarantee for the stable operation of the mixing paddle 32.
[0019] Specifically, the drive assembly 2 includes a mounting box 21 and an L-shaped mounting base 22. A tripod seat 211 is bolted to the side wall of the mounting box 21 and the top wall of the limiting groove 11. The L-shaped mounting base 22 is bolted to the inner wall of the mounting box 21. The rotating motor 23 is wired to a speed regulating seat 232 and a switch button 233. Both the speed regulating seat 232 and the switch button 233 are embedded in the outer wall of the mounting box 21.
[0020] In this embodiment, the side wall of the mounting box 21 of the tripod base 211 is connected to the top wall of the limiting groove 11 by bolts. The tripod base 211 utilizes the stability of the triangular structure to disperse the vibration generated by the drive component 2 during operation. For example, during the operation of the high-speed rotating motor 23, the tripod base 211 can effectively reduce the impact of motor vibration on the mounting box 21, avoiding bolt loosening or structural deformation caused by long-term vibration. This design is particularly common in heavy machinery or high-precision equipment, such as the spindle support structure of CNC machine tools. The L-shaped mounting base 22 is fixed to the inner wall of the mounting box 21 by bolts to form an independent motor mounting module, which is vertical. The dual fixing method of the surface and the horizontal plane not only restricts the axial displacement of the rotating motor 23, but also offsets the radial torque through the rigidity of the L-shaped structure. For example, in the mixing equipment, this design can ensure that the mounting base will not break due to uneven force when the motor outputs large torque. At the same time, it is convenient to quickly disassemble the motor during subsequent maintenance. The speed regulating seat 232 is embedded in the outer wall of the mounting box 21 and is connected to the rotating motor 23 through the wire to realize the stepless speed regulation function. The embedded design of the switch button 233 takes into account both the convenience of operation and safety. Its position is usually located in an easily accessible area on the outer wall of the mounting box 21, so that the operator can quickly cut off the power in an emergency.
[0021] Specifically, a limiting groove 11 is provided on the bottom upper surface of the fixed plate base 1, and the liquid collection tank 4 can be placed inside the limiting groove 11.
[0022] In this embodiment, the contour of the limiting groove 11 matches the outer diameter of the bottom of the liquid collection tank 4, forming a unique placement position, which can ensure that the liquid collection tank 4 is always directly below the stirring head assembly 3, preventing liquid leakage or detection errors.
[0023] Specifically, the rotating rod 24, the cross protrusion 241, the inclined block 242, the wedge block 243, the insert 31, the stirring paddle 32, and the liquid collection tank 4 are all made of plastic.
[0024] In this embodiment, the low density and lightweight design of the plastic make the egg-beating action more effortless and convenient, reducing operator fatigue, improving user experience, and can be used as a disposable replacement part.
[0025] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
