The present utility model relates to a pipette structure including a pipette body 100 and a pipette tip 200.

As shown in fig. 1, 2 and 3, the tube body 100 is a hollow long tubular structure, and is made of silica gel. In the illustrated direction, the lower end of the tube body 100 has a first connection portion 110. Inside the pipe body 100 is a first flow passage 120, and the first flow passage 120 penetrates from the upper end of the pipe body 100 to the bottom of the connection portion. In the embodiment, the suction head 200 is made of hard rubber, the suction head 200 is wrapped with the balancing weight 300, the balancing weight 300 is pre-buried in a die for manufacturing the suction head 200 during production, and the balancing weight 300 is fixed in the suction head 200 by injection molding and other modes. The suction head 200 is provided with a second connecting portion 210, and the second connecting portion 210 is used for being matched with the first connecting portion 110. The second flow path 220 is provided in the cleaner head 200, one end of the second flow path 220 is located on the surface of the cleaner head 200, and the other end extends through to the end of the second connection portion 210. In use, the first connection portion 110 and the second connection portion 210 are detachably connected to each other to connect the vessel 100 to the cleaner head 200. After the first and second connection parts 110 and 210 are assembled with each other, the first and second flow passages 120 and 220 communicate with each other. When the suction tube structure is used, the suction tube structure can be applied to products such as a milk bottle or a water bottle, for example, the suction tube structure is applied to the milk bottle, the upper end of the tube body 100 is connected with the suction head 200 of the milk bottle, the suction tube extends into the milk bottle, the lower end of the tube body 100 and the suction head 200 are settled at the bottom of the milk bottle through the gravity of the balancing weight 300, and therefore liquid at the bottom of the milk bottle is conveniently sucked out. The pipe body 100 and the suction head 200 are detachably connected through the first connecting part 110 and the second connecting part 210, so that the production and the installation of the suction head 200 are convenient, the suction heads 200 with different sizes and the pipe bodies 100 with different lengths can be matched for use, the applicability is improved, and the production cost is reduced.

In some embodiments of the present utility model, as shown in fig. 2 and 4, an annular groove 121 is provided at a position corresponding to the first connection portion 110, that is, at the inner wall of the lower end of the first flow passage 120. The annular groove 121 is disposed around the central axis of the first flow passage 120. As shown in fig. 3, the second connecting portion 210 is cylindrically protruded upward at the upper end of the suction head 200. The second connecting portion 210 has a protruding collar 211 on a circumferential sidewall, and the collar 211 surrounds the central axis of the second flow channel 220. When the connector is installed, the second connecting portion 210 is inserted into the first connecting portion 110, and the snap ring 211 is clamped into the annular groove 121. The detachable connection between the first connection portion 110 and the second connection portion 210 is achieved by the mutual cooperation of the snap ring 211 and the annular groove 121. The outer wall of the snap ring 211 is tightly attached to the inner wall of the annular groove 121, so that on one hand, the connection stability between the first connection portion 110 and the second connection portion 210 is ensured, and on the other hand, the tightness of the butt joint between the first flow channel 120 and the second flow channel 220 can be ensured, so that the liquid in the bottle can stably flow to the first flow channel 120 through the second flow channel 220.

In some embodiments of the utility model, as shown in FIGS. 1 and 2, the cleaner head 200 is provided with a cambered surface 230 that protrudes in the axial direction of the second flow path 220. In the illustrated orientation, the second connecting portion 210 faces upward and the cambered surface 230 faces downward away from the second connecting portion 210. The lower end of the second flow channel 220 penetrates through the center of the cambered surface 230. A plurality of diversion trenches 231 are arranged on the cambered surface 230, and each diversion trench 231 is uniformly distributed around the center of the cambered surface 230. The diversion trench 231 extends along the arc direction of the arc surface 230, and one end of the diversion trench 231 is communicated with the end of the second flow passage 220. When the suction pipe structure is used for sucking liquid, part of liquid can flow into the second flow channel 220 along the diversion trench 231, so that the phenomenon that the lower end of the second flow channel 220 is adsorbed on the bottle wall to block the liquid when the suction head 200 is sunk to the bottom of the bottle can be avoided.

In some embodiments of the present utility model, as shown in fig. 2, 3 and 4, the first connection portion 110 faces the end surface of the second connection portion 210, that is, the lower end surface of the first connection portion 110 is the first plane 111 in the illustrated direction. The end surface of the suction head 200 where the second connection portion 210 is located, that is, the upper end surface of the suction head 200 is a second plane 240. After the first connection portion 110 and the second connection portion 210 are connected, the first plane 111 is abutted with the second plane 240. The first plane 111 and the second plane 240 serve as connection base surfaces, which limit the insertion depth of the second connection part 210 with respect to the first connection part 110, thereby confirming whether the suction head 200 and the tubular body 100 are assembled in place. Wherein the edge outer diameter of the second plane 240 is larger than the edge outer diameter of the first plane 111. The edges of the second plane 240 may be rounded. The tip 200 is easily removed from the vessel body 100 after grasping the edge of the tip 200.

In some embodiments of the present utility model, the balancing weight 300 is annular, and the balancing weight 300 surrounds the second flow passage 220. The balancing weight 300 can ensure that the lower end of the second flow passage 220 is balanced and is settled at the bottom of the bottle to the greatest extent to absorb liquid.
