Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of liquid sampling, in particular to an intelligent pipette with a cleaning function. Background Art
[0002] A pipette, also known as a micropipettor or pipetting gun, is a laboratory device used to measure and transfer liquids. They are widely used in laboratory work in biology, chemistry, medicine, and other scientific fields. The design of the pipette enables it to accurately measure a specific volume of liquid and transfer this liquid to another container.
[0003] When using a pipette to transfer liquid, first rotate the volume adjustment knob on the pipette according to the volume of liquid to be aspirated, then vertically immerse the tip into the liquid to be aspirated, press the piston button of the pipette to the first gear to aspirate the liquid, after aspiration, place the tip into the target container, and press the piston button to the bottom second gear to release the liquid, thus completing the transfer of the liquid. However, manually operating the adjustment knob is prone to errors. Especially in the case of frequent volume adjustment, the experimenter may make mistakes due to fatigue or distraction, resulting in inaccurate aspiration volume of the pipetting, affecting the accuracy of the experimental results. In addition, after the pipette is used, there will be residual liquid inside its outer shell and in the tip, which needs to be cleaned. Most cleaning methods require careful disassembly of the outer shell and removal of the tip according to the instructions in the manual, and then soaking and cleaning with a cleaning agent. This method is time-consuming and laborious, and if the operation is improper, it may damage the pipette or cause parts to be lost.
[0004] Therefore, there is a particular need for an intelligent pipette with a cleaning function to solve the above problems. Summary of the Utility Model

[0024] Embodiment: An intelligent pipette with a cleaning function, refer to Figures 1 - 4As shown in the figure, it includes a housing 1, a micro water pump 2, a connecting pipe 201, a suction pipe 3, a dust cover 4, a controller 5, a touch integrated display 6, a transparent plate 8 and a charging port 12. On the arc surface at the top of the housing 1, there are a plurality of anti-slip grooves evenly spaced and horizontally distributed to increase the friction between the hands of the experimenter and the housing 1. Inside the housing 1, a micro water pump 2 is connected by bolts at the upper right side. The left rear side of the micro water pump 2 is connected with a connecting pipe 201, and the lower end of the connecting pipe 201 is close to the inner bottom of the housing 1 to facilitate sucking the liquid or cleaning agent inside the housing 1. The right side of the micro water pump 2 is plugged with a suction pipe 3, and the outer end of the suction pipe 3 is covered with a dust cover 4 to prevent dust and other impurities from entering the inside of the suction pipe 3. On the left side outside the housing 1, a controller 5 is connected by bolts, and in the middle position of the front side outside, a touch integrated display 6 is connected by bolts. The controller 5 is electrically connected to the micro water pump 2 and the touch integrated display 6. Inside the housing 1, a transparent plate 8 for viewing is embedded at the rear side. On the left front side outside the housing 1, a charging port 12 is connected, and the charging port 12 is connected to the battery of the controller 5. It also includes a cleaning mechanism, and a cleaning mechanism for cleaning the residual liquid is arranged inside the housing 1.
[0025] Refer to Figures 1 - 3 As shown in the figure, the cleaning mechanism includes a motor 90, a scraper 91, a screw 92, a baffle 110, a support block 111 and a telescopic spring 112. A motor 90 is connected by bolts on the left side outside the housing 1. The motor 90 is located below the controller 5 and is electrically connected to it, and a screw 92 is connected to the output shaft through a coupling. The screw 92 is located at the lower part inside the housing 1. A scraper 91 is slidably connected inside the housing 1. The edge of the scraper 91 fits with the inner wall of the housing 1 and is threadedly connected to the outside of the screw 92. And there is a groove on the right side of the scraper 91, so that when the scraper 91 moves to the right limit, it will not press the micro water pump 2. The scraper 91 is made of sealing rubber and has a relatively slow compression stress, which can achieve a good sealing effect. A baffle 110 is slidably connected at the lower right side inside the housing 1, and support blocks 111 distributed front and back are connected by welding. The baffle 110 is made of sealing rubber and has a relatively slow compression stress, which can achieve a good sealing effect. The baffle 110 slides between the two support blocks 111, and telescopic springs 112 distributed front and back are sleeved on the right side. The two ends of the telescopic spring 112 are respectively connected to the support block 111 and the baffle 110.
[0026] Refer to Figure 1 and Figures 4 - 7As shown, it further includes a dust-proof shell 100, a heating wire 101, a fan 102, an electromagnet 103, a sealing plate 104, a return spring 105, a guide post 106, and a convex rod 107. The front side of the outer shell 1 is connected with the dust-proof shells 100 distributed left and right by welding. The touch integrated display 6 is located between the two dust-proof shells 100. A plurality of through holes 108 distributed circumferentially are formed in the rear side of the dust-proof shell 100. The front side inside the dust-proof shell 100 is connected with the heating wire 101 and is connected with the fan 102 by bolts. The fan 102 is located behind the heating wire 101. The rear side inside the dust-proof shell 100 is connected with the guide posts 106 distributed left and right by welding. A sealing plate 104 is slidably connected between the two guide posts 106. The rear side of the sealing plate 104 is connected with a plurality of convex rods 107 distributed circumferentially by welding. Each convex rod 107 is inserted into each through hole 108 one by one, so that the rear side of the dust-proof shell 100 is sealed. The front end of the guide post 106 is connected with the electromagnet 103. There is a certain distance between the electromagnet 103 and the fan 102 to prevent the electromagnet 103 from affecting the rotation of the fan 102. The controller 5 is electrically connected with the heating wire 101, the fan 102, and the electromagnet 103. A return spring 105 distributed left and right is connected between the sealing plate 104 and the dust-proof shell 100. Each return spring 105 surrounds each guide post 106 one by one.
[0027] When it is necessary to use a pipette gun to transfer liquid, first, the experimenter holds the outer shell 1, pulls out the dust cover 4 to open the suction tube 3, then turns on the touch integrated display 6 through the controller 5, and sets the running time of the micro water pump 2 on the touch integrated display 6 according to the volume of the liquid to be pipetted. Subsequently, the suction tube 3 is vertically immersed in the liquid to be transferred, the micro water pump 2 is turned on, and its operation is controlled to suck the liquid into the suction tube 3, and then it is transported through the connecting tube 201 into the outer shell 1. When an appropriate amount of liquid is transported, the micro water pump 2 just reaches the pre-set running time, and the touch integrated display 6 issues an instruction to the controller 5 to control the micro water pump 2 to turn off and stop running. Then, the suction tube 3 is placed into the target container, the micro water pump 2 is turned on again, and its operation is controlled to suck the liquid in the outer shell 1 into the connecting tube 201, and then it is transported to the suction tube 3 and discharged into the target container. After the liquid discharge of the suction tube 3 is completed, the micro water pump 2 is turned off and stops running. Thus, the liquid transfer operation is completed. When it is necessary to clean the pipette gun, the suction tube 3 is vertically immersed in the cleaning agent bottle, and then the above steps are repeated to fill the inside of the outer shell 1 with the cleaning agent. Then, the motor 90 is turned on, and the output shaft of the motor 90 drives the screw 92 to rotate, so that the scraper 91 moves to the right to scrape the residual liquid on the inner wall of the outer shell 1, so that the liquid dissolves in the cleaning agent, and at the same time, the cleaning agent is pushed to the right, so that the cleaning agent squeezes the baffle 110 to move to the right to open the lower part of the outer shell 1, and the telescopic spring 112 is compressed accordingly, and then the cleaning agent is discharged. During this process, the position of the scraper 91 is viewed through the transparent plate 8. When the scraper 91 moves to the right to the limit and all the cleaning agent in the outer shell 1 is discharged, the telescopic spring 112 returns to its original state, prompting the baffle 110 to move to the left to close the lower part of the outer shell 1. Then, the output shaft of the motor 90 is controlled to reverse to drive the screw 92 to reverse, so that the scraper 91 moves to the left to reset. Then, the above steps are repeated with clean water to clean the inside of the outer shell 1 for the second time to remove the residual cleaning agent and any possible residual impurities. Thus, the cleaning operation of the outer shell 1 is completed. Then, the suction tube 3 is pulled out and cleaned separately, and after cleaning, the suction tube 3 is inserted back. Finally, the heating wire 101 and the fan 102 are turned on, and the electromagnet 103 is controlled to be energized. The electromagnet 103 generates magnetism when energized to adsorb the sealing plate 104 to move forward, and the return spring 105 is stretched accordingly. The sealing plate 104 simultaneously drives the convex rod 107 to move forward to disengage from the through hole 108, thereby opening the dust-proof shell 100. The fan 102 operates to suck the outside air into the dust-proof shell 100. After the air is heated by the heating wire 101, it enters the outer shell 1 through the through hole 108, thereby drying the inside of the outer shell 1. After drying is completed, the heating wire 101 and the fan 102 are turned off, and the electromagnet 103 is controlled to be de-energized. The electromagnet 103 no longer generates magnetism to adsorb the sealing plate 104, and the return spring 105 returns to its original state, prompting the sealing plate 104 to move backward, thereby driving the convex rod 107 to move backward and snap into the through hole 108 to close the dust-proof shell 100. When the pipette gun is not needed, the dust cover 4 is covered to close the suction tube 3, and then the charging cable is connected to the charging port 12.The micro water pump 2, the motor 90, the heating wire 101 and the fan 102 are respectively controlled by the controller 5 for charging. After the charging is completed, the connection between the charging wire and the charging port 12 can be disconnected.
[0028] It should be noted that the above steps can be repeated multiple times to clean the inside of the housing 1 until it is completely clean. And when there is less residual liquid in the connecting pipe 201, the residual liquid and cleaning agent inside the connecting pipe 201 can be cleaned during the process of filling the housing 1 with the cleaning agent and clean water.

Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, rather than to limit the present invention, and the scope of protection is defined by the content of the claims.
