[0081] The present application will be described below in conjunction with the accompanying drawings and a specific embodiment.

[0082] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only to represent selected embodiments of the present application.

[0083] It should be noted that: similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it can not be further defined and explained in subsequent drawings.

[0084] Referring to Figures 1 to 5 The quick release homogenizer described in the embodiments mainly consists of a motor 200, a mounting seat 100, a drive shaft 210, a cutter head assembly 300 and a quick release mechanism 400. The motor 200 provides a power source for the entire device, the mounting seat 100 serves to support and connect various components, the drive shaft 210 is responsible for transmitting power from the motor 200 to the cutter head assembly 300, and the cutter head assembly 300 is the core part for realizing the homogenization function, and the design of the quick release mechanism 400 greatly improves the convenience of disassembling and assembling the cutter head assembly 300.

[0085] The mounting seat 100 is provided with a plurality of first pin holes 101 and a first plug hole 102. The first pin holes 101 are arranged in pairs, preferably two pairs, in a circumferential array. These first pin holes 101 correspond precisely with the second pin holes 321 on the second cutter head 320, providing a stable and reliable working basis for the quick-release assembly. The first plug hole 102 is detachably plugged with the second cutter head 320, further enhancing the stability and flexibility of the connection.

[0086] The drive shaft 210 is firmly connected to the output shaft of the motor 200 at one end, and is provided with a second plug hole 211 and a drive pin 212 at the other end. The second plug hole 211 is detachably plugged with the top end of the first cutter head 310, ensuring the stability and flexibility of the connection. The drive pin 212 is tightly connected with the transmission pin 311 on the first cutter head 310, ensuring accurate and efficient power transmission. The motor 200 transmits power to the cutter head assembly 300, driving it to rotate at high speed and providing strong power support for the homogenization process.

[0087] The cutter head assembly 300 includes a first cutter head 310 and a second cutter head 320. The first cutter head 310 is a cylinder, and the second cutter head 320 is a circular tube. The first cutter head 310 is coaxially arranged in the second cutter head 320. After the first cutter head 310 and the second cutter head 320 are assembled, the rotational pair is constrained and axially fully positioned, i.e. the first cutter head 310 can only rotate around the axis and cannot slide in the second cutter head 320.

[0088] The outer wall of the first cutter head 310 is designed with a downward first step 312, and the inner wall of the second cutter head 320 is correspondingly provided with an upward second step 322. When the two cutter heads are assembled together, the first step 312 is stably placed on the second step 322, forming a tight and stable structure. In the preferred embodiment, a bushing 330 is further arranged between the first step 312 and the second step 322. The bushing 330 not only effectively reduces the wear of the cutter head assembly 300 during high-speed operation, but also positions the first cutter head 310, ensuring the stability of the homogenizer.

[0089] The quick release mechanism 400 includes a quick release pin 410, a spring 420, a quick release ring 430, a quick release groove 431, a quick lock ring 432, an upper guide surface 433, a lower guide surface 434, and a limiting plate 440. The quick release pin 410, the spring 420, and the quick release ring 430 form a highly efficient and coordinated work team. The quick release pin 410 is usually arranged in the first pin hole 101 of the mounting seat 100, and the quick release ring 430 controls the extension length of the quick release pin 410, so that the quick release pin 410 can be connected or disconnected with the second pin hole 321 of the second tool head 320, thereby quickly locking or releasing the tool head assembly 300. The limiting plate 440 is fixedly connected with the bottom surface of the mounting seat 100, and accurately limits the sliding stroke of the quick lock ring 432, so that the quick lock ring 432 can slide accurately within a predetermined range, further improving the accuracy and stability of the disassembly of the tool head assembly 300. The quick release ring 430 is provided with the quick release groove 431, the quick lock ring 432 is arranged above the quick release groove 431, the quick lock ring 432 is provided with the upper guide surface 433 and the lower guide surface 434, and the quick release pin 410 is in sliding cooperation with the continuous curved surface formed by the upper guide surface 433, the quick lock ring 432, the lower guide surface 434, and the quick release groove 431. The upper guide surface 433 and the lower guide surface 434 are inclined surfaces or curved surfaces, which facilitate the switching of the quick release pin 410 between the quick lock ring position and the quick release groove position when the quick lock ring 432 slides up and down. In addition, the sliding stroke of the quick lock ring 432 on the mounting seat 100 is equal to the width of the quick lock ring 432 plus the width of the lower guide surface 434 plus the width of the quick release groove 431 minus the diameter of the quick release pin 410. It is recommended that the width of the quick lock ring 432, the width of the quick release groove 431, and the diameter of the quick release pin 410 are equal. This design ensures the stable sliding of the quick release pin 410 in the quick release groove 431, avoids the problems of looseness or jamming caused by size mismatch, and further improves the reliability and durability of the quick release mechanism 400.

[0090] When the quick release pin 410 is in contact with the quick release groove 431, the quick release pin 410 is separated from the second pin hole 321, and at this time the tool head assembly 300 is in the process of assembly or disassembly. When the quick release ring 430 is slid downward, the quick release pin 410 is in contact with the quick lock ring 432, the quick release pin 410 slides in the first pin hole 101, the spring 420 is compressed, the quick release pin 410 is inserted into the second pin hole 321, the second pin hole 321 is coaxially aligned with the first pin hole 101, and the second tool head 320 is completely locked. Under the positioning action of the plurality of quick release pins 410, the homogenizer is in a high-speed working state, and the tool head assembly 300 and the mounting seat 100 always remain stable.

[0091] In the installation of the tool head assembly 300, the operator only needs to plug the tool head assembly 300 into the mounting seat 100 and the driving shaft 210, and then easily lock the tool head assembly 300 on the mounting seat 100 and the driving shaft 210 through the cooperation of the quick release pin 410 and the quick release ring 430 of the quick release mechanism 400. The whole installation process does not need to use any tool, and the operation is simple and fast, which greatly saves time and labor cost.

[0092] When it is necessary to disassemble the tool head assembly 300 for cleaning, maintenance or replacement, the operator can easily pull out the tool head assembly 300 by sliding the quick release ring 430 upwards, sliding the quick release pin 410 from the quick lock ring 432 to the quick release slot 431, and completely exiting the quick release pin 410 from the second pin hole 321 under the action of the spring 420. The quick disassembly design makes the cleaning and maintenance of the tool head assembly 300 extremely convenient, effectively avoids the hygiene problem caused by sample residue, reduces the maintenance cost, and also provides a powerful guarantee for the efficient operation of the equipment.

[0093] In the homogenization operation process, the motor 200 drives the driving shaft 210 to rotate at high speed, and the power is transmitted to the tool head assembly 300 through the connection of the driving pin 212 and the transmission pin 311. When the tool head assembly 300 rotates at high speed, strong shearing force, impact force and cavitation effect are generated, so that the sample to be detected and the solvent are fully mixed and uniformly mixed, and finally the standard solution required for detection is reached. The whole homogenization process is efficient and stable, and can meet the homogenization needs of various samples in the laboratory.
