Embodiment Construction

[0037] An embodiment of the present invention relates to a needle combination device, such as shown in Figures 1 to 4C The needle assembly 10 in.

[0038] Such as Figure 1 to Figure 3AAs shown, the needle assembly 10 includes a needle housing 40 for movably mounting the needle bundle 200 therein. The needle housing 40 is formed by a tubular body portion 400 , a mouth portion 100 and a cap portion 500 . The needle housing 40 has a tubular longitudinal passage 420 therein. The tubular longitudinal channel 420 has an upper open end 422 and a lower open end 424 . The mouth 100 is provided at the lower open end 424 , and the cap 500 is provided at the upper open end 422 . As will be described in detail later, the mouth 100 has a guide surface 122 for guiding the movement of the needle and delivering ink to the needle (see Figure 3A ). The tubular longitudinal channel 420 may be formed by the tubular body portion 400 which may have the viewing window 410 .

Abstract

The invention relates to a needle assembly for a liquid applicator, and a liquid applicator. The needle assembly for a liquid applicator includes a housing comprising a tubular longitudinal channel and a guide / inner surface. The channel comprises an upper open end and a lower open end. Liquid storage grooves for storing liquid by capillary action extend generally transversely in the guide / inner surface above the lower open end. A needle bundle is mounted in the housing. The needle bundle comprise one or more needles longitudinally reciprocally movable in the channel and being biased against the guide surface, or towards the inner surface, across the grooves such that, during longitudinal reciprocal movement of the needle bundle, the needle bundle maintains contact with the guide surface and the liquid stored in the grooves, or maintains a capillary gap between the needle bundle and the inner surface, for drawing the liquid out of the grooves by capillary action. The needle assembly fora liquid applicator can realize stable and effective liquid transfer.

Description

technical field [0001] The present invention relates to devices for applying liquids to the skin, and more particularly to liquid applicating devices and disposable disposable needle assemblies utilizing capillary action to deliver ink or other liquids in such liquid applying devices. Background technique [0002] A tattoo device generally includes a tattoo needle for applying ink to the skin, a tattoo machine with a tattoo needle driver, and a tattoo needle that is connected to the tattoo machine and can be conveniently held in the operator's hand to manipulate the tattoo during use. Needle handle. Examples of tattoo devices are disclosed in, for example, US patent US6505530, US patent US8454643, Chinese patent CN204745346, and Chinese patent CN201595866, and US patent application 15 / 691125. [0003] For safety reasons, tattoo needles should generally be sterilized before use and replaced after each use. It is therefore convenient to use a replaceable and disposable tatto...
