Description

Technical Field

[0001] This utility model relates to the field of hair dyeing pen technology, specifically a hair dyeing pen. Background Technology

[0002] Hair dye pens are convenient hair dyeing tools suitable for home use. Existing hair dye pens use cotton wicks to store water. When the water volume is large and full, the liquid is easily shaken or splashed out during transportation, causing ink splattering. The applicant's previous application has solved this problem by adding a cotton wick cover.

[0003] The applicant discovered in actual production that due to technical barriers in manufacturing cotton wicks, it is difficult to produce wicks with a diameter greater than 20mm. This makes it impossible to produce large-diameter wicks with a fixed length, affecting the overall canning capacity and failing to meet the consumer market's demand for large-capacity wicks. In addition, the cotton wick itself absorbs a large amount of liquid during use, and this liquid remains inside the wick and cannot be utilized. After a period of use, as the liquid volume decreases, the liquid color lightens, and a large portion of the remaining material inside the wick cannot be fully extracted and utilized, resulting in waste.

[0004] Therefore, a hair dye pen is needed to improve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a hair dyeing pen to solve the problems mentioned in the background art.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, the ink reservoir is set separately, containing only liquid. Its internal liquid storage capacity is maximized to meet the needs of large-capacity use. The liquid in the ink reservoir is introduced into the cotton core through the water inlet core. The edge of the water inlet core hole has an air vent groove to maintain the balance of internal and external air pressure when water is introduced outward. Once the cotton core is saturated, it stops absorbing water and simultaneously supplies the absorbed liquid to the fiber head, achieving the functions of water control and supply, and playing a role in water intake regulation. The reduction in the size of the cotton core greatly reduces the waste caused by the final residual material in the cotton core not being fully utilized. Attached Figure Description
