Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and grasped.

As shown in fig. 1 and 2, the utility model discloses automatic imbibition burette device, including liquid storage bottle 1 and lid, the lid includes inner cup 2, enclosing cover 3, button 4 and piston 7, and inner cup 2 fixed connection is inside enclosing cover 3, is formed with a burette 21 on inner cup 2, button 4 and inner cup 2 sliding connection, and be equipped with spring 5 between button 4 and the inner cup 3, piston 7 one end is connected with button 4, and piston 7 is in inner cup 2, just piston 7 can take place the displacement in inner cup 2, just piston 7 is in burette 21 top, when automatic imbibition burette device is the encapsulated situation, burette 21 inserts in the liquid storage bottle 1, the bottleneck threaded connection of button 4 and liquid storage bottle 1, just button 4 drives piston 7 and shifts down in inner cup 2. When the automatic liquid suction and dropping tube device is in an open state, the button 4 is separated from the liquid storage bottle 1, and the spring 5 drives the button 2 to bounce, so that the piston 7 moves upwards in the inner cover 2.

Specifically, as shown in fig. 3 to 7, the inner lid 2 includes a dropper 21, an inner cylinder 22 and an outer cylinder 23, the outer cylinder 22 is hollow, the inner cylinder 22 is located in the outer cylinder 23, the inner cylinder 22 and the outer cylinder 23 are connected by a connecting portion 27, an opening 271 is formed on the connecting portion 27, the dropper 21 is located below the inner cylinder 22, and the dropper 21 is communicated with the inner cylinder 22, and the whole inner lid 2 is integrally formed. The inner side surface of the top surface of the button 4 is provided with a connecting piece 42, one end of the piston 7 is connected with the connecting piece 42, the piston 7 is positioned in the inner cylinder 22 of the inner cover 2, and the piston 7 can displace in the inner cylinder 22. The button 4 is formed with a plate 44, a lower edge of the plate 44 passes through the opening 271, and a screw 41 for screw coupling is formed on an inner wall of the plate 44.

The outer wall of button 4 is equipped with joint portion 43, and the inner wall of inner cup 2 is equipped with spout 24, the joint portion 43 of button 4 is spacing in the spout 24 of inner cup 2 for button 4 can take place the displacement along its axis direction in inner cup 2. The outer wall of inner cup 2 is equipped with joint groove 25 and joint portion 26, and the inner wall of enclosing cover 3 is equipped with joint portion and joint groove respectively corresponding to the position of joint groove 25 and joint portion 26.
