Problems solved by technology

Many patents have improved the appearance of traditional ear washing balls, such as CN302995235S and CN302995238S, but they have not fundamentally solved the instability of the ear washing balls when they are used for a small amount or a small amount of liquid absorption; CN204034734U has announced a convenient The controllable and easy-to-clean pipette overcomes the difficulty of cleaning the pipette. At the same time, the amount of solution absorbed can be controlled by pushing and pulling the rubber piston. There is a great deal of instability

Embodiment 1

[0020] Embodiment 1 Use plexiglass as the shell material to make a pressure fine-tuning device for ear washing balls:

[0021] Prepare 6 plexiglass plates that can be made into cuboids (length 7.6cm, width 6.1cm, height 6.1cm), 5 of which are fixed with adhesive to form a cuboid shell (the right side is not installed), and the left side Open a round hole in the middle of the surface, just to let the long mouth of the ear washing ball pass through, install the right plexiglass plate, open a round hole in the middle of the plate, so that the bolt with the protective cover just passes through, and grind a nut-shaped shallow hole on the outside of the round hole. Groove and fix the nut; finally use 4 sets of screws to reinforce the whole pressure trimming device. main view as figure 1 shown. The ear washing ball pressure fine-tuning device has a regular and beautiful shape, simple and stable operation, and a long service life.

Embodiment 2

[0022] Example 2 Use recycled disposable tea cups as shells to make a pressure fine-tuning device for ear washing balls:

[0023] Recycled disposable open-mouthed tea cup with slightly hard texture (large diameter 6.4cm, small diameter 4.4cm), a round hole is punched in the middle of the bottom of the cup so that the long mouth of the ear washing ball just passes through, and a square plastic plate (length 7cm, width 7cm) is used as the cup The lid is fixed on the mouth of the cup. A round hole is drilled in the center to allow the bolt with the protective sleeve to pass through, and a shallow groove in the shape of a nut is ground on the outside of the round hole to fix the nut. main view as figure 2 shown. The shell material of the ear washing ball pressure fine-tuning device is cheap and easy to obtain, energy-saving and environment-friendly, and the manufacturing process is simple.

Embodiment 3

[0024] Example 3 Use waste plastic bottles as the shell to make a pressure fine-tuning device for ear washing balls:

[0025] The bottle containing the chewing gum is a double-layer cylindrical shell with an inner diameter slightly larger than the outer diameter of the ear wash ball. There is a round hole in the bottom of the inner cylindrical material, which can just pass through the long mouth of the ear wash ball, in the middle of the bottle cap. Drill a round hole so that the bolt with the protective sleeve can pass through, and fix the nut with glue on the outside of the round hole. main view as image 3 shown.

[0026] The shell material of the ear washing ball pressure fine-tuning device is cheap and easy to obtain, energy-saving and environment-friendly, the manufacturing process is simple, and it is solid and durable.

Abstract

The invention discloses a method for manufacturing an ear washing bulb pressure fine-adjustment device. The device comprises 1, a housing, 2, an ear washing bulb, 3, bolts / nuts and 4, a protection sleeve. The method comprises processing two opposite surfaces of the housing to form circular holes in the surface centers, wherein a long nozzle of the ear washing bulb goes through one of the circular holes and the bolt with the protection sleeve goes through the other one of the circular holes, polishing the outer side of the circular hole at the bolt end to form a nut-shaped shallow groove and fixing the nut through glue. The pressure fine-adjustment device is prepared from organic glass or waste and old plastic, the raw materials save energy and are environmentally friendly, manufacturing and operation processes are simple, the pressure fine-adjustment device can be used for controlling most of micro-liquids, and the pressure fine-adjustment device can guarantee smooth and accurate experiment process.

Description

technical field [0001] The invention relates to the field of energy-saving and environment-friendly manufacturing experimental equipment, in particular to a method for making a pressure fine-tuning device for ear washing balls made of waste plastics and its application. Background technique [0002] The application field of ear washing ball is very wide. Because of its good practicability, convenient materials and simple production, it is widely used in fields such as chemistry, medicine and health, and engineering. However, the existing ear washing ball cannot accurately complete the experimental operation because it is greatly affected by human factors. Often due to improper human operation, it is impossible to accurately control when pipetting or dripping liquid. For example, in the experiment of measuring the surface tension of liquid in the laboratory, when we used the ear washing ball to perform the drop operation, we found that the original ear washing ball could no...
