Quantitative Burette Device

Abstract

A quantitative dropper device, comprising a locking seat, an elastic suction piece pierced in the locking seat, a dropper pierced in the elastic suction piece, a quantitative metering tube sleeved outside the locking seat Seat, a button that passes through the locking seat and the quantitative seat and is located above the elastic suction piece, and a rotating seat that is sleeved outside the quantitative seat and can be rotated. The locking seat includes a base portion and a first surrounding wall extending upward from the base portion. The first surrounding wall defines a piercing space communicating with the base portion, and a chute unit communicating with the piercing space. The elastic suction piece can push up the button. The quantitative seat includes a quantitative surrounding wall sheathed outside the first surrounding wall and defining at least one quantitative unit. The quantitative unit has several quantitative grooves with different depths. The button includes a positioning unit passing through the corresponding chute unit and the quantitative groove. The rotating seat can drive the quantitative seat to rotate relative to the locking seat.

Description

technical field [0001] The invention relates to a weighing and measuring equipment, in particular to a quantitative dropper device capable of quantitative suction. Background technique [0002] Beauty care liquid is a must-have skin care product for many women, and there are many types. Generally, the beauty care liquid is contained in a container with a pressure head. By pressing the pressure head, the beauty care liquid flows out Or spray it out for use, but for some higher-end high-priced beauty care liquids, the spray-like way of taking it will cause unnecessary waste, and the traditional design of the pressure head will cause the beauty care liquid to remain on the skin. The pressure head is in the pipeline and cannot be used, so the above-mentioned general pressure head is not suitable for taking some higher-level beauty care liquids. In view of this, manufacturers usually use droppers to take these higher-level beauty care liquids. The current dropper structure rough...

[0002] Beauty care liquid is a must-have skin care product for many women, and there are many types. Generally, the beauty care liquid is contained in a container with a pressure head. By pressing the pressure head, the beauty care liquid flows out Or spray it out for use, but for some higher-end high-priced beauty care liquids, the spray-like way of taking it will cause unnecessary waste, and the traditional design of the pressure head will cause the beauty care liquid to remain on the skin. The pressure head is in the pipeline and cannot be used, so the above-mentioned general pressure head is not suitable for taking some higher-level beauty care liquids

In view of this, manufacturers usually use droppers to take these higher-level beauty care liquids. The current dropper structure roughly includes a straw and a set of elastic extrusion heads placed on the top of the straw. Press and release the extrusion head to make the straw absorb beauty care liquid, but this kind of dropper cannot be stable and quantitative. Although there may be a scale on the surface of the straw, you have to watch the scale carefully every time you use it. It is quite inconvenient to control the dosage, so there is still room for improvement in the traditional dropper container
