The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0023] Example: like Figure 1-3 As shown, this embodiment provides an electric pipette, including a pipette frame 1, a vacuum pump 2, a buffer tank 3, a liquid dispenser 4, a connecting tube 5, a connecting valve 6, a control circuit board 7, a multi-port pipette seat 8, and a controller 9; Vacuum pump 2, buffer tank 3, and control circuit board 7 are located on pipette holder 1; The multi-port pipe socket 8 has an inlet end 801 and several outlet ends 802; The port of vacuum pump 2 is connected to one port of buffer tank 3 through connecting pipe 5. The other port of buffer tank 3 is connected to the inlet end 801 of multi-port pipe seat 8 through connecting pipe 5. The outlet end 802 of multi-port pipe seat 8 is connected to connecting pipe 5. Liquid dispenser 4 is detachably connected to connecting pipe 5 located at outlet end 802 of multi-port pipe seat 8. The connecting valve component 6 is located at the connection between the outlet end 802 of the multi-port pipe seat 8 and the connecting pipe 5; The liquid dispenser 4 includes a lower liquid dispensing pipe 401, a middle liquid retention pipe 402 and an upper connecting pipe 403. The middle liquid retention pipe 402 is connected to and communicates with the lower liquid dispensing pipe 401 and the upper connecting pipe 403 respectively. The upper connecting pipe 403 is detachably connected to the connecting pipe 5 located at the outlet end 802 of the multi-port pipe seat 8. The control circuit board 7 is electrically connected to the vacuum pump 2, the connecting valve 6, and the controller 9.

[0024] The electric pipette in this embodiment activates the vacuum pump 2 via the control circuit board 7, drawing the test liquid into the central retention tube 402 of the pipette 4 using the pipette 4. Then, the opening of the upper connecting tube 403 of the pipette 4 is sealed, and the entire pipette 4 is moved to the desired location for placing the test liquid. This achieves automated pipetting, facilitating manual operation, and is highly practical with significant results. Simultaneously, the opening and closing state of a single outlet end 802 of the multi-port pipette 8 is controlled by the connecting valve 6, adjusting the liquid-taking state of the pipette 4 connected to the corresponding outlet end 802, facilitating automated control and adjustment.

[0025] The buffer tank 3 is designed to prevent the test liquid from entering the vacuum pump 2 directly and causing damage if the user does not turn off the vacuum pump 2 in time after turning it on.

[0026] The pipette holder 1 in this embodiment includes a vertical frame 101 and a horizontal frame 102. The horizontal frame 102 is disposed on the vertical frame 101, and the multi-port tube seat is disposed on the horizontal frame 102. The bottom of the vertical frame 101 may be provided with a connecting seat that connects to the workbench.

[0027] A flow channel is provided inside the multi-port pipe seat 8. The flow channel is arranged along the length extension direction of the multi-port pipe seat 8 and is respectively connected to the inlet end 801 and the outlet end 802. The inlet end 801 is located at one end of the multi-port pipe seat 8, and the outlet end 802 is located on the outer wall surface of the multi-port pipe seat 8.

[0028] In this embodiment, there are four outlet ends 802. Each outlet end 802 can be connected to a liquid dispenser 4. The user can adjust the connecting valve 6 of each outlet end 802 according to the needs of the usage scenario to control one or more liquid dispensers 4 to perform liquid dispensing.

[0029] The control circuit board 7 in this embodiment includes a control unit 701 and a signal transceiver unit 702. The control unit 701 is electrically connected to the signal transceiver unit 702, the vacuum pump 2, and the connecting valve 6.

[0030] Specifically, controller 9 is connected to control unit 701 via signal transceiver unit 702.

[0031] Specifically, the signal transceiver unit 702 is a WIFI receiver module, an infrared receiver module, or a Bluetooth receiver module.

[0032] Specifically, controller 9 is a remote control that wirelessly connects to signal transceiver unit 702, and the remote control has multiple function buttons.

[0033] In the above structure, the user can wirelessly connect to the control circuit board 7 via a remote control, which facilitates the user to wirelessly control the working status of the vacuum pump 2 and the connecting valve 6.

[0034] In this embodiment, the liquid dispenser 4 is made of rubber. A pipe clamp 10 is provided at the upper connecting pipe 403. The pipe clamp 10 includes a pipe clamp seat 1011 and a pipe clamp body 1012. One end of the pipe clamp body 1012 is connected to the pipe clamp seat 1011, and the other end forms a clamping area with the pipe clamp seat 1011. The size of the clamping area can be adjusted. Specifically, the pipe clamp 10 is made of plastic.

[0035] Specifically, the pipe clamp body 1012 has an arc-shaped structure, and the pipe clamp body 1012 and the pipe clamp seat 1011 form a mating port 1013 that mates with the upper connecting pipe 403.

[0036] After the liquid dispenser 4 draws the test liquid into the retention tube 402 of the dispenser 4, the user can move the other end of the clamp body 1012 away from the clamp seat 1011 to increase the size of the clamping area. After moving the upper connecting tube 403 to the clamping area, the force on the clamp body 1012 is released, making the size of the clamping area smaller. The clamp 10 clamps the upper connecting tube 403 and seals it, ensuring the retention of the test liquid in the retention tube 402 of the dispenser 4. The connection between the dispenser 4 and the outlet end 802 of the multi-port pipe seat 8 is released, and the dispenser 4 is moved to the position where the test liquid needs to be placed. Then, the clamp 10 is released from the clamping and sealing state of the upper connecting tube 403, thus realizing the transfer of the test liquid in the retention tube 402 to the container where the test liquid is placed, achieving the effect of automated liquid transfer.

[0037] Meanwhile, the liquid dispenser 4 in this embodiment is a transparent part, and there are scales on the liquid retention tube 402, so that users can easily observe and know the amount of liquid in the liquid dispenser 4.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
