Definitions

  • the present disclosure generally relates to a mixer for fluid components or fluid agents, especially a mixer for generating a hair dye by mixing the fluid components or fluid agents.
  • a composite fluid material prior to be used or distributed, may be produced by mixing at least two fluid components.
  • a hair dye is considered as such a composite fluid material.
  • the hair dye is comprised of two fluid components, such as fluid agents.
  • the two fluid components or fluid agents are separately stored in their respective cartridges. This is because the fluid components or fluid agents are chemically active. Therefore, prior to being mixed with each other to generate the hair dye, they have to be hermetically stored in the cartridges. When necessary, the fluid components or fluid agents will be discharged from their respective cartridges and be mixed with each other to generate the hair dye. In order to guarantee the quality of the generated hair dye, they need be mixed evenly and quickly.
  • the fluid components or fluid agents may be manually discharged from the cartridges onto a plane or into a container and mixed with each other manually by a rod which is used to stir the discharged fluid components or fluid agents.
  • the discharged fluid components or fluid agents are exposure to air and smell pungent, thus discomforting a worker.
  • the quality of the hair dye generated by manual stirring will greatly depend on the worker's experience.
  • the hair dye generated by mixing needs to be applied or distributed onto a person's hair in a shorter time. Otherwise, the hair dye exposure to air for a long term before its application or distribution onto the hair will be deteriorated and thus the final hair coloration effect will be negatively affected.
  • mixers for generating a hair dye from two fluid components or fluid agents found in the market, some of them do not mix the fluid components or fluid agents, some of them cannot mix the fluid components or fluid agents evenly, some of them can be used only once, and the others of them are not compact enough for usage.

  • the notch 3425 is configured to substantially align with the middle position of the straight second middle ridge 3422.
  • the barrier 3424 is substantially between the notch 3425 and the inlet opening 3423.
  • the facing sides of the second mixing member 342 and of the discharge member 38 are complementarily recessed such that the second mixing pathway will have two second straight mixing pathway branches parallel to each other.
  • one of the second mixing pathway branches (the lower one in Fig. 6) is longer than the other of the second mixing pathway branches (the upper one in Fig. 6) .
  • the two second mixing pathway branches are connected to each other at or adjacent to one lateral end of the second mixing member 342 and/or the discharge member 38.
  • each second mixing pathway branch has a substantially circular cross-section.
  • Each second mixing pathway branch is sized such that a mixing rod 36 can be placed in the second mixing pathway branch. Therefore, the mixing rod 36 in the longer second mixing pathway branch is longer than the mixing rod 36 in the other second mixing pathway branch.
  • the mixing rods 36 of the second mixing pathway are formed similar to the mixing rods 36 of the first mixing pathway and correspondingly placed in the respective second mixing pathway branches. Therefore, after the fluid components or fluid agents has flowed through the first mixing pathway and stirred or mixed with each other through the same, they will continue to flow through the second mixing pathway.
  • the fluid components or fluid agents entering the inlet opening 3423 will be deflected by the barrier 3424 and thus can flow only along a direction represented by a dotted arrow as shown by Fig. 6, to the notch 3425.
  • the fluid components or fluid agents will be continuously stirred or mixed by the petals of the mixing rods 36 of the second mixing pathway although the mixing rods may be stationary in the second mixing pathway.
  • the discharge member 38 is formed with a spray port 32 which is for example in the form of a tube.
  • the spray port 32 aligns with the notch 3425. Therefore, after the fluid components or fluid agents have flowed through the second mixing pathway, the already stirred or mixed fluid components or fluid agents can be sprayed out of the spray port 32 for direct usage of hair coloration.
  • the spray port 32 is configured to protrude from the body 1 of the mixing head 3 through both the first notch 1c of the body 1 and the notch 3733 of the seat 37.
  • the inlet opening 3423 of the second mixing pathway is adjacent to the other lateral end of the second mixing member 342 opposite to the one lateral end at or adjacent to which the two second mixing pathway branches are connected to each other. Therefore, this enables the second mixing pathway to extend between the second mixing member 342 and the discharge member 38 by a maximized length.
  • the lengths of the first and second mixing pathways are maximized in the seat 37 such that the fluid components or fluid agents discharging out of the cartridges can be stirred or mixed as over a long distance and/or quickly and/or evenly as possible.
  • the seat 37, the first mixing member 341, the second mixing member 342 and the discharge member 38 can be secured to each other by any suitable mechanical means, for example bonding or ultrasonic welding, to ensure fluid-tightness therebetween.
  • the seat 37, the first mixing member 341, the second mixing member 342, the mixing rods 36, and the discharge member 38 can be regarded to constitute a mixing assembly in which the first and second mixing pathways are provided.
  • the mixing assembly is selectively slidable in the body 1 of the mixing head 3 between a first state, in which the seat 37 is in its released state, and a second state, in which the seat 37 is in its pressed state.
  • a cover 5 can be installed in the body 1 of the mixing head 3 longitudinally opposing the base 2.
  • the cover 5 is formed with several tabs 53 (for example four, as shown by Fig. 9) which are distributed along an outer circumferential edge of the cover 5.
  • Those tabs 53 are configured to be snapped into the body 1 of the mixing head 3, especially into an opening edge of the body 1 of the mixing head 3 such that an exposure side of the cover 5 flushes with the opening edge of the body 1, resulting in both securing of the cover 5 relative to the body 1 and aesthetic appearance of the assembled mixer.
  • the cover 5 is integrally formed with a cantilever part 51 which is accessible from the exposure side of the cover 5 and is configured to contact the discharge member 38 when the cover 5 is installed in the body 1 of the mixing head 3.
  • the cantilever part 51 can be formed with several bulges 54, which are spaced from each other, such that the cover 5 is in contact with the discharge member 38 only via the bulges 54 when the cover 5 is installed in the body 1 of the mixing head 3.
  • the cantilever part 51 is integrally formed with a button part 52 which is in the second notch 1d of the body 1 when the cover 5 is installed in the body 1 of the mixing head 3.
  • the second notch 1d is sized that when the cantilever part 51 or the button part 52 is pressed, the button part 52 is freely movable in the second notch 1d.
  • a groove-shaped shelter part 55 is formed in the cover 5 opposing the button part 52 and is configured to be located in the first notch 1c when the cover 5 is installed in the body 1 of the mixing head 3, not affecting protrusion of the spray port 32 from the body 1 of the mixing head 3.
  • the existence of the groove-shaped shelter part 55 will visually conceal the majority portion of the discharge member 38 and/or the basin part 373, thus contributing to aesthetic appearance of the assembled mixer.
  • the seat 37 is connected together with the discharger member 38, moving the discharger member 38 longitudinally will enable the seat 37 to slide in the body 1 of the mixing head 3.
  • the first notch 1c is sized such that the spray port 32 of the discharge member 38 can be freely moved in the first notch 1c when the mixer has been assembled in place.
  • the mixing assembly is in its first state. As the cantilever part 51 or the button part 52 is pressed by a user, it will drive the mixing assembly via the discharge member 38 to slide from the first state to the second state.
  • the mixing assembly can be held in its second state during which the pressurized fluid components or fluid agents can be discharged out of the cartridges due to the face that the resilient or activation parts thereof are pressed by the tubes 371 of the seat 37, and the discharged fluid components or fluid agents will flow through the first and second mixing pathways sequentially and be stirred or mixed with each other by the mixing rods 36 arranged therein such that the well stirred or mixed fluid components or fluid agents can be finally sprayed from the spray port 32.
  • the resilient or activation parts are also released such that the pressurized fluid components or fluid agents are prevented from discharging out of the cartridges respectively and thus under the action of the resilient or activation parts the mixing assembly is able to return to its first state.
  • an additional mixing pathway similar to the first or second mixing pathway can be provided in the mixing assemble so as to enhance the mixing effect of the fluid components or fluid agents as soon as the pressure of the discharged fluid components or fluid agents from the cartridges is sufficient to support the smooth flow and stirring or mixing of them through the mixing pathways.
