[0017] In order to make the technical problems, technical solutions and beneficial technical effects of the utility model to be solved clearer, the following will further describe the utility model in combination with the drawings and multiple exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model, and are not used to limit the protection scope of the utility model.

[0018] It should be understood that, in this paper, the expressions "first", "second", etc. are only used for descriptive purposes, and should not be understood as indicating or implying relative importance, nor should it be understood as implicitly indicating the number of the indicated technical features. The features limited by "first", "second" can be explicitly or implicitly indicated to include at least one feature.

[0019] As Figures 1-5The capsule cup bottom membrane puncture mechanism shown is disposed on the lower side of the bottom membrane 12 of the capsule cup body 1. The capsule cup body 1 includes a cup body 10 and a cup bottom 11. The bottom membrane 12 is fixed to the bottom of the cup body 10, and the cup bottom 11 is provided with an outlet 13. The feature is that a receiving cavity 100 is formed between the bottom membrane 12 and the cup bottom 11. A puncture needle assembly 2 is provided in the receiving cavity 100. The cup bottom 11 is configured to deform when subjected to external force, so that when the cup bottom 11 is subjected to an upward external force, it can drive the puncture needle assembly 2 to move closer to the bottom membrane 12 and puncture the bottom membrane 12.

[0020] The needle assembly 2 includes a guide plate 20 and a plurality of needles 21 disposed on the upper surface of the guide plate 20. When the needle assembly 2 approaches the bottom membrane 12, the needles 21 pierce the bottom membrane 12. The outlet 13 is located at the center of the cup bottom 11. A plurality of guide holes 200 are provided at the edge of the guide plate 20, and a plurality of guide channels 201 converging from the edge to the center are provided at the bottom of the guide plate 20. One end of the guide channel 201 is connected to the guide hole 200, and the other end of the guide channel 201 is connected to the outlet 13. A flow-guiding boss 22 is provided at the center of the bottom surface of the guide plate 20, and the flow-guiding boss 22 extends into the outlet 13.

[0021] The cup bottom 11 is configured as an arc-shaped curved surface with a lower center and higher edges, and the outlet 13 is located at the center of the cup bottom 11; the cup bottom 11 can undergo elastic deformation when subjected to a preset external force. In some embodiments, the cup bottom is made of a thin plastic sheet, which has a certain supporting strength and is not easily deformed under small pressure, but is easily deformed under large pressure, thereby driving the needle assembly closer to the bottom membrane.

[0022] Referring to the accompanying drawings, the principle of this utility model is as follows: Figure 1 As shown, in its natural state (unused state), the needle assembly 2 is located within the receiving cavity 100, and the needle 21 does not exert pressure on the substrate, keeping the substrate intact; as Figure 4 As shown, when the capsule cup is inserted into the capsule support 3, the pressure plate 4 presses down, and the bottom of the capsule support 3 exerts an upward force on the bottom of the cup, causing the bottom of the cup to deform upward. This, in turn, pushes the needle assembly upward and punctures the bottom membrane. The liquid inside the capsule cup then flows out from the bottom membrane and flows out along the guide hole 200, the guide channel 201, and the outlet 13. This structure utilizes external force to exert pressure on the bottom of the cup, causing the needle assembly to actively move upward and actively puncture the bottom membrane. The overall structure is stable, and the bottom membrane puncture is more reliable.

[0023] In the description of the utility model, need understanding is, up and down, left and right, inner end, outer end, one end, another end and so on the direction or position relation indicated based on the position or position relation shown in the drawing, only is for more clearly convenient for describing the technical scheme of the utility model, and is not the device or the element indicated or implied must have a specific direction, with a specific position structure and operation, can not be understood as the limitation to the utility model.

[0024] Although the specific embodiments of the utility model are described in detail here, they are only given for the purpose of explanation, and should not be considered as limiting the scope of the utility model. Various alternatives, changes and modifications can be conceived without departing from the spirit and scope of the utility model.
