Description

Technical Field

[0001] This application relates to the field of laboratory equipment technology, and more specifically to a digital quantitative bottle mouth dispenser. Background Technology

[0002] In laboratory environments, accurately extracting a specific volume of reagent from a vial is a common task. Traditional methods typically rely on pouring from a graduated cylinder or drawing from a pipette, which are not only inefficient but also pose safety hazards, especially with highly corrosive or toxic chemicals. Therefore, bottle-top dispensers have emerged to provide precise and highly repeatable dispensing operations, ensuring safety for operators and the experimental environment. However, most existing bottle-top dispensers operate manually, requiring multiple manual operations for large-volume dispensing needs, resulting in low efficiency. Furthermore, the reagent comes into direct contact with the dispenser's inner wall, making it susceptible to contamination and affecting the accuracy of experimental results. Therefore, developing an efficient, safe, accurate, and compact automated dispenser is of paramount importance. Summary of the Invention

It will also be understood that the terms “comprising” and / or “having” as used in this specification specify the presence of the described features, numbers, steps, operations, components, elements or combinations thereof, without excluding the presence or addition of one or more other features, numbers, steps, operations, components, elements or groups thereof.

[0027] refer to Figures 1 to 4 According to a preferred embodiment of the present invention, a digital quantitative bottle-top dispenser is described, wherein the structure of the digital quantitative bottle-top dispenser is as follows: Figure 2 As shown, it includes a bottle body 10, the bottle body 10 having a first cavity 101 with an opening, and the opening being located at the top of the bottle body 10. It should be noted that the reagent solution is placed inside the first cavity 101.

[0028] Specifically, the digital quantitative bottle-mouth dispenser also includes a first connecting shell 20, the structure of which is as follows: Figure 2 As shown, one end of the first connecting shell 20 has a connecting hole 201, which is threadedly connected to the end of the bottle body 10 with the opening. It should also be noted that the bottom wall forming the connecting hole 201 has an insertion hole, the two ends of which connect the connecting hole 201 to the outside.

[0029] Specifically, the digital quantitative bottle-top dispenser further includes a second connecting shell 30, one end of which has a third cavity 301, and the end of the second connecting shell 30 with the third cavity 301 is fixedly connected to the first connecting shell 20. Specifically, the connection between the second connecting shell 30 and the first connecting shell 20 can be implemented as a screw connection, and the first connecting shell 20 and the second connecting shell 30 form a shell assembly. Furthermore, when the first connecting shell 20 is fixed to the second connecting shell 30, the insertion hole communicates with the third cavity 301.

[0030] Specifically, the digital quantitative bottle-top dispenser further includes a drive assembly, which is fixed within the third chamber 301. For example... Figure 2As shown, the digital quantitative bottle-top dispenser further includes an inlet pipe 40 and an outlet pipe 50. One end of the inlet pipe 40 is located at the bottom of the first cavity 101, and the other end passes sequentially through the opening of the first cavity 101, the connecting hole 201, and the insertion hole, and is connected to the drive assembly. One end of the outlet pipe 50 is connected to the drive assembly, and the other end is located externally. It is worth noting that the drive assembly is configured to guide the solution from the inlet pipe 40 to the outlet pipe 50, thereby creating a pressure difference between the inlet pipe 40 and the outlet pipe 50, allowing the solution to be quantitatively output from the bottle 10. It should be noted that the drive assembly can be implemented as a motor 60 and a peristaltic pump 70. The motor 60 is located in the third cavity, and one end of the peristaltic pump 70 cooperates with the motor 60, while the other end is located at the top of the second connecting shell 30. The motor 60 can be a stepper motor 60.

[0031] It is worth mentioning that one side of the second connecting shell 30 also has a protrusion 31. The protrusion 31 has a flow hole. One end of the flow hole is connected to the outside, and the other end is connected to the third cavity 301. The peristaltic pump 70 has a pump tube 71. The pump tube 71 is located outside and is connected to one end of the flow hole. The inlet pipe 40 is connected to the other end of the flow hole. The outlet pipe 50 is connected to the peristaltic pump 70. That is, the solution is guided from the inlet pipe 40 to the pump tube 71 and then from the pump head of the peristaltic pump 70 to the outlet pipe 50.

[0032] It should also be noted that a display screen 80 is installed on one side of the second connecting shell 30, and a main control circuit board (not shown in the figure) is also installed in the third cavity 301. The main control circuit board is connected to the display screen 80 and the motor 60 respectively. Specifically, the main control circuit board is directly connected to the tail of the motor 60 by four screws. Those skilled in the art should understand that the display screen 80 is a capacitive touch screen with integrated serial port interaction functionality. Two input boxes are designed on the screen to receive the dispensing volume and dispensing speed set by the user. A "Start Output" and a "Stop Output" button are also designed on the screen. When the user clicks the "Start Output" button, the display screen 80 communicates with the main control circuit board via serial port signal, transmitting the user-set dispensing volume and dispensing speed data to the main control circuit board. After receiving the data, the main control circuit board performs calculations to determine the corresponding number of pulses and pulse frequency. A pulse signal generator is designed on the main control board. After completing the calculations, the main control board actively generates the correct pulse signal and sends it to the stepper motor 60. The motor shaft of the stepper motor 60 is connected to the peristaltic pump 70. The stepper motor 60 rotates according to the received pulses, driving the peristaltic pump 70. During operation, the peristaltic pump 70 squeezes the pump tube 71, creating a pressure difference between the inlet pipe 40 and the outlet pipe, causing the solution to be quantitatively output from the bottle 10. The functions of the display screen 80 described above are for illustrative purposes only and are not the focus of this utility model.

[0033] It should also be noted that a circular magnetic sheet is installed at the bottom of the motor shaft of the stepper motor 60. During the rotation of the motor shaft, the magnetic sheet is driven to rotate and form a rotating magnetic field. A magnetic induction sensor is provided on the main control circuit board to monitor the speed and number of revolutions of the motor 60 in real time in a closed loop. If the motor 60 loses steps, the main control circuit will compensate to ensure that the peristaltic pump 70 reaches the predetermined number of revolutions.

[0034] It is worth mentioning that the side wall of the first connecting shell 20 also has a vent 202, the two ends of which are connected to the outside and the connecting hole 201 respectively, so as to maintain the pressure balance inside and outside the bottle 10.

[0035] In summary, the digital quantitative bottle cap dispenser described in the embodiments of this application is explained, which provides advantages such as high efficiency, safety, accuracy, and compact layout.

[0036] It is worth mentioning that, in this embodiment, the digital quantitative bottle cap dispenser has a simple structure, does not involve complex manufacturing processes or expensive materials, and is highly economical. At the same time, for manufacturers, the digital quantitative bottle cap dispenser provided in this application is easy to produce and inexpensive, which is more conducive to controlling production costs and further facilitates product promotion and use.
