The receiving tube is located at the center of one side of the storage tube, and the storage tube and the receiving tube are interconnected. The discharge component is located at one end of the inner tube of the storage tube, with a portion of the discharge component extending into the outer tube of the storage tube. The inner tube of the storage tube is provided with a partition, and the discharge component is located on one side of the partition. This utility model, by setting up a storage tube, a discharge component, and a receiving tube, achieves the effect of providing material to the analyzer multiple times after a single extraction.

[0004] However, the above-mentioned patent still has the following defects: such as powder flowability and clogging risk. Although the "one end is large and the other end is small" design of the feed hopper in the application can prevent backflow, it can cause clogging for sticky, moist or easily caking powders. For example, material accumulates in the narrow part of the feed hopper, so it cannot meet the use requirements. Therefore, a portable device for cream particle size detection is proposed to solve the problems mentioned above. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 4This embodiment discloses a portable device for detecting the particle size of cream, comprising a sampling structure for detecting the particle size of cream. The sampling structure includes a storage tube 1 and a sampling tube 2. The sampling tube 2 is fixedly connected to the top side of the storage tube 1, and the sampling tube 2 is fixed to the storage tube 1 by bolts or threads. A piston cylinder 3 is provided at one end of the storage tube 1. It should be noted that the storage tube 1 is hollow inside, and a partition 101 is fixed to the inner side of the storage tube 1, dividing the storage tube 1 into two chambers, namely a first chamber 102 and a second chamber 103. The piston cylinder 3 is disposed inside the second chamber 103, and a through hole is provided inside the partition 101 to connect the first chamber 102 and the second chamber 103. Specifically, multiple triangular elastic plates (not shown in the figure) are provided inside the through hole, and the sidewalls of two adjacent triangular elastic plates abut against each other. A suction pipe extending into the first chamber 102 is installed on one side of the piston cylinder 3. A discharge pipe is provided on the bottom side of the piston cylinder 3.

[0026] In this embodiment, a driving mechanism is provided on the outside of the storage tube 1. The driving mechanism includes an electric telescopic rod 6 located outside the storage tube 1. An adjusting plate 7 is fixed to the output end of the electric telescopic rod 6. Two connecting rods 8 are provided on the adjusting plate 7. One connecting rod 8 is connected to the piston cylinder 3, and the other connecting rod 8 is provided with a striking block 11 for striking the sampling tube 2. The adjusting plate 7 has a wave groove 71 that cooperates with the connecting rod 8. The connecting rod 8 consists of a connecting rod 81 and a roller 82. One end of the connecting rod 81 is rotatably connected to the roller 82, and the roller 82 rolls against the inner side of the wave groove 71. Specifically, the two connecting rods 8 are distributed vertically. The end of the bottom connecting rod 81 away from the roller 82 is fixed to the piston bolt inside the piston cylinder 3, and the end of the top connecting rod 81 away from the roller 82 is fixed to the outer surface of the striking block 11 by bolts. The trajectory design of the wave groove 71 allows for adjustment of the striking frequency and amplitude. Furthermore, a protective pad 12 is fixed to the inner side of the arc-shaped groove, and two limiting seats 10 are fixed to the upper surface of the storage tube 1. Through the ingenious cooperation of the adjusting plate 7, the wave groove 71, and the two connecting rods 8 distributed vertically, the piston in the piston cylinder 3 can be driven to move simultaneously to complete the sampling operation, and the striking block 11 can be driven to strike the sampling tube 2 to promote the flow of cream, all relying on only one power source, the electric telescopic rod 6. This design reduces the number of driving components required for the equipment, simplifies the structure, reduces costs, and at the same time improves the integration and ease of operation of the equipment.

[0027] It should be noted that the striking block 11 has an arc-shaped groove on the side near the sampling tube 2, which can better conform to the shape of the sampling tube 2, increase the contact area during striking, and make the striking force more evenly distributed on the sampling tube 2, thus improving the striking effect. A buffer spring 13 is fixed between one of the limiting seats 10 and the striking block 11. The combination of the protective pad 12 and the buffer spring 13 reduces mechanical impact, extends the service life of the sampling tube 2 and the striking block 11, and improves the convenience of cream particle size detection. A limiting bracket for limiting the bottom connecting rod 81 can also be installed on the outside of the piston cylinder 3.

[0028] In this embodiment, a support structure for fixing the electric telescopic rod 6 is provided on the bottom side of the storage pipe 1. The support structure includes a mounting plate 4 fixed to the bottom side of the storage pipe 1, a connecting plate 5 welded to one side of the mounting plate 4, and the electric telescopic rod 6 fixed to the upper surface of the connecting plate 5 by bolts. A guide rail 9 for limiting the adjustment plate 7 is fixed to the upper surface of the connecting plate 5, and one side of the adjustment plate 7 slides with the guide rail 9. The support structure provides a stable fixing platform for the electric telescopic rod 6 through the mounting plate 4 and the connecting plate 5. The mounting plate 4 is fixed to the bottom side of the storage pipe 1, ensuring a firm connection between the entire support structure and the storage pipe 1; the connecting plate 5 is welded to one side of the mounting plate 4, and the electric telescopic rod 6 is fixed to the upper surface of the connecting plate 5 by bolts. This fixing method is simple and reliable, and can withstand various forces generated by the electric telescopic rod 6 during operation, ensuring the stable operation of the electric telescopic rod 6.

[0029] The working principle of the above embodiments is as follows:

[0030] The electric telescopic rod 6 is activated, and its output end drives the adjustment plate 7 to move. Since the adjustment plate 7 slides with the guide rail 9, the stability of the movement of the adjustment plate 7 is ensured. During the movement of the adjustment plate 7, the roller 82 of the bottom connecting rod 8 rolls in the wave groove 71 inside the adjustment plate 7. Due to the shape characteristics of the wave groove 71, the bottom connecting rod 8 reciprocates. The bottom connecting rod 8 drives the piston inside the piston cylinder 3 to move. The piston cylinder 3 is set in the second chamber 103 of the storage tube 1. Through the through hole on the partition plate 101, the first chamber 102 is made to generate negative or positive pressure, thereby realizing the cream sampling operation.

[0031] Simultaneously, the roller 82 of the top connecting rod 8 also rolls within the wave groove 71, driving the top connecting rod 8 to reciprocate. The top connecting rod 8 drives the striking block 11 to move. The striking block 11 has an arc-shaped groove on the side near the sampling tube 2, and a protective pad 12 is fixed inside the arc-shaped groove to prevent damage to the sampling tube 2. During its movement, the striking block 11 strikes the sampling tube 2, allowing the cream inside the sampling tube 2 to flow out smoothly, facilitating subsequent particle size detection. A buffer spring 13 is fixed between the striking block 11 and one of the limiting seats 10, which acts as a buffer during the striking process, reducing equipment vibration and improving equipment lifespan.

[0032] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
