[0033] In order to describe this utility model in detail, the stirring rod cleaning device of this utility model will be described in detail below:

[0034] Please combine Figures 1 to 5 As shown, this utility model provides a stirring rod cleaning device, including: a cleaning cup body 10 and a cleaning core body 20, wherein the cleaning cup body 10 is provided with a cleaning inlet 12, a cleaning mounting cavity 11 and a cleaning outlet 13, the cleaning inlet 12 is connected to the side wall of the cleaning mounting cavity 11, and the cleaning outlet 13 is connected to the bottom of the cleaning mounting cavity 11; the cleaning core body 20 is disposed in the cleaning mounting cavity 11, the peripheral side wall of the cleaning core body 20 is provided with an annular groove 21, the interior of the cleaning core body 20 is provided with a cleaning flow channel 22 extending along its own axial direction, the annular groove 21 is provided with a water inlet hole 23 communicating with the cleaning flow channel 22, and the cleaning inlet 12 is aligned with the annular groove 21.

[0035] Specifically, the cleaning installation cavity 11 is used to accommodate the cleaning core 20 and discharge the cleaning liquid, the cleaning inlet 12 is used to introduce the cleaning liquid into the cleaning installation cavity 11, and the cleaning outlet 13 is used to discharge the waste liquid after cleaning. The cleaning inlet 12 is located on the side wall of the cleaning cup 10 and communicates with the side wall of the cleaning installation cavity 11. The cleaning outlet 13 is located on the bottom wall of the cleaning cup 10 and communicates with the bottom of the cleaning installation cavity 11. The cleaning core 20 is disposed in the cleaning installation cavity 11. The cleaning liquid enters the cleaning installation cavity 11 through the cleaning inlet 12. Since the cleaning inlet 12 is aligned with the annular groove 21, the cleaning liquid flows along the annular groove 21 and is flushed into the cleaning channel 22 from the water inlet 23 on the annular groove 21 to rinse the stirring rod located in the cleaning channel 22. The annular groove 21 accelerates the flow of the cleaning fluid. The cleaning fluid enters the cleaning channel 22 inside the cleaning core 20 through the inlet hole 23 on the annular groove 21, enabling a rinsing-like cleaning of the agitator rod, resulting in better cleaning performance. The cleaning fluid enters the cleaning channel 22 through the annular groove 21 to clean the agitator rod. This method reduces fluid loss in the channel area, avoids prolonged fluid retention in dead zones, reduces the risk of cross-contamination, and improves cleaning and maintenance efficiency.

[0036] See Figure 4In some embodiments, the cleaning mounting cavity 11 is vertically connected to the cleaning cup body 10, and the cleaning inlet 12 is connected to the cleaning mounting cavity 11 and aligned with the annular groove 21 through the inlet channel 14. The inlet channel 14 is horizontally connected to the cleaning cup body 10. Specifically, the vertical connection of the cleaning mounting cavity 11 to the cleaning cup body 10 allows the cleaning fluid to flow smoothly and effectively clean all parts of the stirring rod; the horizontal connection of the inlet channel 14 to the cleaning cup body 10 not only optimizes the flow path of the cleaning fluid but also improves the cleaning efficiency. When the cleaning fluid flows in from the cleaning inlet 12, it can quickly enter the annular groove 21 through the inlet channel 14, thereby cleaning the stirring rod in all directions; the annular groove 21 can be provided with upper and lower layers. This design eliminates the need for assembly. Regardless of the orientation of the cleaning core 20, the cleaning fluid can be ensured to enter the cleaning channel 22 from each inlet hole 23 to clean the stirring rod. Furthermore, the annular groove 21 effectively reduces the velocity difference (or flow rate difference) of the cleaning fluid entering from the inlet holes 23 of the cleaning core 20 and rinsing the stirring rod, thus more effectively removing residues from the stirring rod. Simultaneously, this design improves assembly efficiency, making the assembly between the cleaning core 20 and the cleaning cup 10 simpler and faster, even when the inlet holes 23 are set eccentrically. Due to the structure of the annular groove 21, there is no need to precisely consider the alignment of the inlet holes 23 during the assembly of the cleaning core 20 and the cleaning cup 10. Because regardless of the setting of the inlet holes 23, the cleaning fluid can smoothly flow into the annular groove 21 through the inlet channel 14, thus achieving effective cleaning of the stirring rod. This feature not only simplifies the assembly process but also reduces assembly difficulty, improving the reliability and stability of the entire cleaning device.

[0037] Continue reading Figure 4In some embodiments, the annular groove 21 spirally surrounds the cleaning core 20, and at least two water inlet holes 23 are provided circumferentially along the cleaning core 20, with the water inlet holes 23 inclined downwards, and the end cleaning surface of the water inlet hole 23 being higher than the highest liquid level surface of the stirring rod during stirring. Specifically, the spiral design of the annular groove 21 surrounding the cleaning core 20 allows the cleaning fluid to form a continuous spiral flow within the annular groove 21. This spiral flow pattern reduces fluid loss in the flow channel area, prevents prolonged fluid retention in dead zones, reduces the risk of cross-contamination, and improves cleaning and maintenance efficiency. Multiple water inlets 23 can simultaneously introduce cleaning fluid, increasing the efficiency of the cleaning fluid entering the cleaning channel 22 and thus accelerating the cleaning speed. The downward-sloping water inlets 23 allow the cleaning fluid to rinse the stirring rod from top to bottom, effectively removing residues from the stirring rod. This rinsing method is not only efficient but also prevents liquid from splashing onto the outside of the cleaning cup 10, maintaining cleanliness throughout the cleaning process. More importantly, the end cleaning surface of the water inlet 23 is higher than the highest liquid level of the stirring rod during the stirring process, ensuring that any part of the stirring rod is fully covered and cleaned by the cleaning fluid even during the stirring process.

[0038] See Figures 5 to 6 In the above embodiment, the top of the cleaning installation cavity 11 has a mounting base 15, and the top of the cleaning core 20 has a mounting part 24, which is snapped onto the mounting base 15; the mounting part 24 is provided with an overflow guide groove 25 on the side away from the mounting base 15, and a plurality of notches are provided on the outer peripheral wall of the overflow guide groove 25 along the circumference of the cleaning core 20. Specifically, the cleaning core 20 is connected to the mounting base 15 at the top of the cleaning mounting cavity 11 via the mounting part 24. The mounting part 24 and the mounting base 15 are structurally compatible and can be locked together by fasteners. The installation method is simple and reliable, and it is convenient to quickly assemble the cleaning core 20 and the cleaning cup 10. The mounting part 24 of the cleaning core 20 is also provided with an annular overflow guide groove 25. The overflow guide groove 25 is lower than the top of the cleaning channel 22, so that the cleaning liquid overflowing in the cleaning channel 22 can overflow through the overflow guide groove 25, thereby avoiding the overflow liquid from flowing back into the cleaning channel 22 of the cleaning core 20 and causing secondary pollution.

[0039] Continue reading Figure 4It should be noted that the cleaning installation cavity 11 includes a core installation section 111, a connecting section 112, a diameter reduction section 113, and a connector installation section 114 connected in sequence. The diameters of the core installation section 111, the connecting section 112, and the diameter reduction section 113 gradually decrease. The cleaning core 20 is located inside the core installation section 111, and the cleaning drain port 13 is located at the end of the connector installation section 114. Specifically, the core mounting section 111 is used to install the cleaning core 20. The connecting section 112 is located after the core mounting section 111, and its diameter gradually decreases, serving as a transition and guide. It also helps to prevent waste liquid from splashing onto the cleaning part and stirring rod of the cleaning core 20 during the moment the forced discharge is activated or deactivated, thus avoiding cross-contamination. The diameter reduction section 113 has a smaller aperture than the connecting section 112 and the core mounting section 111. The end of the diameter reduction section 113 connected to the connecting section 112 has a tapered structure that is larger at the top and smaller at the bottom, which can prevent waste liquid from remaining in dead corners and causing crystallization or bacterial growth over time. The tapered structure facilitates the complete discharge of waste liquid or more effectively discharges waste liquid into the cleaning drain port 13, and the cleaning drain port 13 enables forced suction of the cleaning waste liquid. The diameter reduction section 113 and the cleaning drain port 13 reduce the retention of cleaning waste liquid in the flow channel, improve the discharge efficiency of waste liquid, and thus keep the flow channel clean and unobstructed.

[0040] See Figure 4 and Figure 5 It is understood that a first sealing ring 31 is provided between the mounting portion 24 of the cleaning core 20 and the mounting base 15, and a second sealing ring 32 is provided between the bottom end of the cleaning core 20 and the bottom end of the core mounting section 111. The first sealing ring 31 ensures a seal between the mounting portion 24 of the cleaning core 20 and the mounting base 15 of the cleaning cup 10, and the second sealing ring 32 ensures a seal between the bottom end of the cleaning core 20 and the cleaning mounting cavity 11. This prevents the cleaning fluid from being directly sucked away by the forced discharge or overflowing from the top of the cleaning core 20 into the overflow cavity 16 without entering the chute.

[0041] See Figure 5 In some embodiments, the cleaning cup 10 is further provided with an overflow chamber 16, which is located at the top of the cleaning cup 10. The cleaning mounting cavity 11 communicates with the overflow chamber 16, and the mounting base 15 is located within the overflow chamber 16. Specifically, under normal circumstances, the cleaning waste liquid after cleaning is forcibly pumped out through the cleaning drain port 13. However, if the forced drainage at the cleaning drain port 13 fails, the cleaning waste liquid may overflow the cleaning channel 22. In this case, the overflow chamber 16 can contain this overflowing cleaning liquid, thereby preventing the cleaning waste liquid from further overflowing into the equipment and causing damage or contamination.

[0042] Continue reading Figure 5It is understood that the cleaning cup body 10 is also provided with an overflow channel 17, which communicates with the overflow cavity 16 and is arranged parallel to the cleaning installation cavity 11. An overflow inlet 18 is provided between the overflow channel 17 and the overflow cavity 16. Specifically, the overflow channel 17 is used to discharge the cleaning fluid in the overflow cavity 16 through the overflow inlet 18, thus preventing the accumulation of cleaning waste fluid inside the equipment. This automatic discharge mechanism greatly improves the efficiency and safety of the cleaning process. The overflow channel 17 is parallel to the cleaning installation cavity 11, which helps to save space and makes the entire structure more compact and reasonable. The overflow channel 17 is set with an irregularly shaped staggered structure, which includes a first overflow section and a second overflow section connected to each other. The axis of the second overflow section is staggered from that of the first overflow section, and the second overflow section is at least partially connected to the first overflow section. The overflow channel 17 is parallel to the cleaning installation cavity 11, which helps to save space and makes the entire structure more compact and reasonable. This design is compact and ensures that overflowing waste liquid can be effectively discharged through overflow channel 17.

[0043] Continue reading Figure 5 In the above embodiment, the bottom of the cleaning cup 10 is provided with an overflow drain port 19, which is connected to the overflow channel 17, and an overflow connector 43 is connected to the overflow drain port 19. Specifically, when cleaning fluid overflows from the cleaning channel 22 into the overflow chamber 16 during the cleaning process, this liquid can smoothly reach the overflow drain port 19 at the bottom through the overflow channel 17, and the cleaning waste liquid can be effectively discharged. The overflow drain port 19 is located at the bottom of the cleaning cup 10, and due to gravity, the cleaning waste liquid will naturally flow to the bottom, which is conducive to the smooth discharge of the cleaning waste liquid and reduces the possibility of the cleaning waste liquid remaining inside the equipment. The overflow connector 43 connected to the overflow drain port 19 can facilitate the connection of a suitable drain pipe or other draining equipment.

[0044] See Figure 4 It is understood that an inlet connector 41 is connected to the cleaning inlet 12, and a drain connector 42 is connected to the cleaning outlet 13. The inlet connector 41 facilitates the connection of a suitable inlet pipe or other inlet device; the drain connector 42 facilitates the connection of a suitable drain pipe or other drain device. These features not only make the inlet and outlet processes more convenient and controllable, but also improve the versatility and adaptability of the equipment.

[0045] In summary, the stirring rod cleaning device provided by this utility model, by setting a cleaning core 20 inside the cleaning cup 10, and setting an annular groove 21 on the cleaning core 20 and a water inlet hole 23 on the annular groove 21 that communicates with the cleaning flow channel 22, allows the cleaning liquid to be accelerated from the cleaning inlet 12 through the annular groove 21 and then flushed into the cleaning flow channel 22 through the water inlet hole 23 to rinse the stirring rod located in the cleaning flow channel 22. This reduces the risk of contamination and cross-contamination during the stirring rod cleaning process, improves the cleaning effect of the stirring rod, increases the cleaning efficiency of the stirring rod, and reduces the difficulty of disassembly and assembly.

[0046] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
