[0033] In order to better understand the above technical solution, the above technical solution will be explained in detail in the following combining with the drawings of the specification and specific embodiment.

[0034] (Example 1)

[0035] like Figures 1 to 3 The filling needle cleaning device shown includes a cleaning head 1 and a waste discharge pipe 2. Multiple cleaning heads 1 are arranged along the length of the waste discharge pipe 2 to simultaneously clean multiple filling needles, improving cleaning efficiency. The inlet of each filling needle is connected to a storage tank containing cleaning agent or compressed gas, and is detachably inserted into the corresponding cleaning head 1, forming a sealed cleaning chamber surrounding the lower part of the filling needle. A drain pipe 3, connected to the waste discharge pipe 2, is located in the cleaning chamber above the media submersion level of the filling needle. During cleaning, the cleaning agent or compressed gas flows through the filling needle to clean its inner wall. Subsequently, thanks to the existence of the cleaning chamber, it is temporarily stored, thereby cleaning or drying and sterilizing the outer wall of the filling needle. Finally, it flows from the drain pipe 3 into the same drain pipe 3 and is discharged.

[0036] Specifically, the cleaning head 1 is installed at an angle towards the drain pipe 3 on the waste pipe 3, preferably between 30° and 45°. This allows the cleaning liquid flowing from the filling needle to more easily form mixed flow and rise, creating a reverse impact on the outer wall of the filling needle, achieving excellent cleaning results. The cleaning head 1 is a cleaning tube with a cylindrical inner cavity 1-1. The top of the inner cavity 1-1 has an opening, and the filling needle is inserted into the inner cavity from the opening. The outer diameter of the upper part matches the inner diameter of the inner cavity, achieving a sealed contact between the upper part of the filling needle and the inner cavity, forming a cleaning chamber. This ensures that the filling needle is centrally positioned within the cleaning chamber, guaranteeing that the outer wall of the filling needle can be thoroughly cleaned, achieving a better cleaning effect. The bottom of the inner cavity is hemispherical, allowing the cleaning agent to better flow back at the bottom of the cleaning chamber, creating an impact and improving the cleaning effect. The diameter of the drain pipe 3 is greater than or equal to the diameter of the inlet of the filling needle, which accelerates the drainage and prevents the cleaning liquid from accumulating and not being able to drain out of the drain pipe in time, thus forming a high pressure expansion force, which in turn impacts the connection between the filling needle and the cleaning head, damaging the stability of the sealing connection.

[0037] The upper part of the inner cavity is provided with a first annular groove 1-2 opened on the cleaning tube. A sealing ring 1-3 is fitted inside the first annular groove 1-2. The inner ring of the sealing ring 1-3 fits tightly with the filling needle, improving the sealing of the cleaning cavity and preventing leakage during the cleaning process.

[0038] The upper portion of the first annular groove 1-2 is provided with a locking mechanism 4, and the filling needle and the cleaning pipe are detachably connected through the locking mechanism 4, which can quickly fix and effectively prevent the filling needle from falling off. Specifically, the outer circle of the filling needle is provided with a second annular groove, and the locking mechanism 4 comprises a mounting buckle 4-1 fixedly installed on the outer wall of the cleaning head, a spring pin 4-2 elastically installed in the mounting buckle 4-1 through a spring, and the spring pin 4-2 is arranged along the radial direction of the cleaning head and the tail end is inserted into the second annular groove, so that the locking is quickly achieved, the structure is simple, and the disassembly and assembly are convenient. In order to improve the overall structural stability of the filling needle inserted into the cleaning head, a plurality of locking mechanisms 4 can be uniformly arranged along the circumference of the cleaning pipe.

[0039] The working process of the embodiment is as follows:

[0040] The filling needle is inserted into the cleaning pipe and locked by the locking mechanism 4;

[0041] The cleaning agent, which can be water at different temperatures or corresponding cleaning solvents, is continuously introduced into the storage tank, the valve of the filling needle is opened to form a passage, so that the cleaning agent can flow out of the filling needle to clean the inner wall of the filling needle;

[0042] When the cleaning agent flows out of the outlet of the filling needle, it will accumulate and rise in the cleaning cavity. Since the cleaning pipe is inclined, the cleaning liquid flowing out of the filling needle will form a mixed flow and rise, and the cleaning liquid flowing back from the bottom of the cleaning cavity will form a reverse impact, which together completes the cleaning of the outer wall of the filling needle. When the cleaning liquid rises to the drain pipe, it is collected into the waste pipe and finally discharged;

[0043] After the cleaning agent is cleaned, purified compressed air is introduced into the storage tank to clean the residual cleaning agent in the pipeline and the bottom of the cleaning pipe, so that the residual cleaning liquid in the pipeline is discharged from the filling needle, and the residual cleaning liquid at the bottom of the cleaning pipe is discharged from the drain pipe;

[0044] When the residual cleaning agent is cleaned to a set state and no obvious water is visible, high-temperature compressed gas is introduced into the storage tank to dry and sterilize the inner wall of the pipeline and the inner wall of the cleaning pipe and the outer wall of the filling needle. The hot gas flow completes the heating and temperature maintenance of each part, sublimates the residual water droplets, and then dries and maintains the temperature for high-temperature sterilization;

[0045] Considering that some cleaning agents contain substances that are not soluble in water or form crystals after drying, normal-temperature compressed gas and high-temperature compressed gas can be repeatedly introduced for drying and sterilization. Repeated blowing can discharge the substances, and the residual moisture can be blown out again or the sterilization can be performed multiple times.

[0046] Finally, the locking mechanism is opened, the filling needle is separated from the cleaning device, and the cleaning is completed.

[0047] The cleaning head and the filling needle form a cleaning cavity, and when the filling needle is cleaned, the cleaning agent or compressed gas can be temporarily stored in the cleaning cavity, so that the outer wall of the filling needle can also be cleaned in the process of cleaning the inner wall of the filling needle, meeting the dual-purpose of one machine; meanwhile, the waste liquid discharged after cleaning is recycled through the liquid discharge pipe, the outer wall of the filling needle is circularly cleaned, compressed gas can be introduced to dry and sterilize the filling needle, liquid dripping on the equipment is avoided, and an overall cleaning effect is formed.

[0048] The above-described specific embodiments further specifically describe the purpose, technical scheme and beneficial effects of the utility model, and it should be understood that the above-described specific embodiments are only specific embodiments of the utility model and are not used to limit the utility model, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
