Detailed Description

The technical solution of the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention.

Referring to fig. 1 and 2, an aluminum bubble extruding apparatus according to an embodiment of the present invention is used for extruding aluminum bubbles on a microfluidic chip to extrude a solution in the aluminum bubbles to the outside, and includes a base 10, a lead screw 20, a driving mechanism 30, and an extruding member 40. The base 10 has a first end face 10a and a second end face 10b disposed opposite to each other and a side face 10c connecting the first end face 10a and the second end face 10b, and is provided with a mounting hole 11 extending in a longitudinal direction (a vertical direction shown in fig. 1), wherein the mounting hole 11 may be disposed through the first end face 10a, the second end face 10b, the first end face 10a and the second end face 10b, and in practice, it is preferable that the mounting hole 11 penetrates through the first end face 10a and the second end face 10 b.

The lead screw 20 is assembled in the mounting hole 11 and comprises a lead screw body 21 and a nut 22, the lead screw body 21 is connected with the extrusion piece 40, the nut 22 is sleeved outside the lead screw body 21, the nut 22 and the lead screw body 21 are in threaded connection, and the nut 22 can rotate relative to the base 10. In practice, the nut 22 may be mounted in the mounting hole 11 by a bearing and may rotate relative to the base 10 under the action of the bearing. During the rotation process, the nut 22 converts the rotation motion into the linear motion of the lead screw body 21, so that the lead screw body 21 can drive the extrusion piece 40 to move.

The driving mechanism 30 is installed on the side surface 10c of the base 10 and connected to the nut 22 in the installation hole 11 to drive the nut 22 to rotate. By providing the driving mechanism 30 on the side surface 10c of the base 10, the space occupied by the aluminum bulb extruding device in the longitudinal direction can be reduced, so that the installation of other parts and/or mechanisms can be facilitated.

Specifically, as shown in fig. 2, the nut 22 includes a nut body 22a and a first conical gear 22b, the first conical gear 22b is connected to the driving mechanism 30, the driving mechanism 30 drives the nut 22 to integrally rotate through the first conical gear 22b, and the nut 22 drives the lead screw body 21 to move during rotation. In this embodiment, the nut body 22a and the first conical gear 22b are integrally formed, but in other embodiments, the nut body 22a and the first conical gear 22b may also be designed in a split manner, and the nut body and the first conical gear 22b are integrally connected by corresponding connecting members, such as the nut 22.

As shown in fig. 2, the driving mechanism 30 includes a second conical gear 31 and a power source 32 for driving the second conical gear 31 to rotate, the second conical gear 31 is engaged with the first conical gear 22b, and the power source 32 is connected to the second conical gear 31. In implementation, the power source 32 drives the second bevel gear 31 to rotate, the second bevel gear 31 drives the nut 22 to rotate through the first bevel gear 22b meshed with the second bevel gear, the nut 22 further drives the lead screw body 21 to move, the lead screw body 21 drives the extrusion piece 40 to move to the position of the aluminum bubble, so that the aluminum bubble is extruded, and the solution in the aluminum bubble is extruded to the outside. In the present embodiment, the power source 32 is preferably a rotary electric machine.

As shown in fig. 2, the extruding member 40 has an overall cylindrical structure, and the end surface contacting the aluminum bulb is outwardly protruded to form an arc-shaped extruding surface 41. By arranging the arc-shaped extrusion surface 41, the solution in the aluminum bubbles can be completely extruded. In this embodiment, the extrusion member 40 is preferably made of a flexible material to avoid damage to the aluminum bubbles during the extrusion process.

As shown in fig. 2, in order to accurately control the moving stroke of the lead screw body 21, the aluminum bulb extruding device further comprises a limit switch 50, and a trigger 60 matched with the limit switch 50 is arranged on the lead screw body 21. The cooperation here means that when the trigger 60 triggers the limit switch 50, the limit switch 50 outputs an active signal to the control system. In practice, when the trigger 60 is close to the limit switch 50, the limit switch 50 outputs an effective signal to the control system, and the control system further controls the power source 32 to stop working. In this embodiment, limit switch 50 is preferably a proximity switch.

Further, in order to control the stroke of the lead screw body 21 to adapt to different application scenarios, for example, in some application scenarios, the lead screw body 21 needs to move for a longer distance, and in some application scenarios, the lead screw body 21 needs to move for a shorter distance, so that the stroke of the movement of the lead screw 20 can be controlled by adjusting the position of the trigger 60, that is, the position of the trigger 60 on the lead screw body 21 is adjustable.

The utility model also discloses equipment for controlling the micro-fluidic chip to detect a target object, which comprises at least one aluminum bubble extrusion device. Because the aluminum bubble extrusion device can reduce the occupied space, the equipment tends to be more miniaturized and portable.

The driving mechanism 30 is arranged on the side surface 10c of the base 10, so that the occupied space of the aluminum bulb extruding device in the longitudinal direction is reduced, and the installation of other parts and/or mechanisms is facilitated.

Therefore, the scope of the present invention should not be limited to the disclosure of the embodiments, but includes various alternatives and modifications without departing from the scope of the present invention, which is defined by the claims of the present patent application.
