Mixer for Fluid ComponentsFIELD
[0001] 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.BACKGROUND
[0002] Sometimes, a composite fluid material, prior to be used or distributed, may be produced by mixing at least two fluid components. In the field of cosmetics, a hair dye is considered as such a composite fluid material. Usually, the hair dye is comprised of two fluid components, such as fluid agents. Before the hair dye will be applied or distributed onto a person's hair, 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. Conventionally, 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. In this case, the discharged fluid components or fluid agents are exposure to air and smell pungent, thus discomforting a worker. Moreover, the quality of the hair dye generated by manual stirring will greatly depend on the worker's experience.
[0003] Furthermore, 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.
[0004] Although there are some 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.SUMMARY
[0005] In order to solve the above issues, the present disclosure is aimed at proposing a novel and compact mixer for fluid components such that the fluid components when passing the mixer can be mixed with each other evenly and quickly without human experience and thus the mixed final product after being discharged out of the mixer can be for direct usage.
[0006] According to one aspect, the present disclosure proposes a mixer for fluid components, comprising:
[0007] a mixing head having a body and configured to releasably receive at least two cartridges for storing different pressurized fluid components therein; and
[0008] a mixing assembly slidably installed in the body of the mixing head, wherein at least a first mixing pathway and a second mixing pathway are defined in the mixing assembly respectively at different planes substantially perpendicular to a direction along which the mixing assembly is selectively slidable between a first state, in which fluid components to be mixed are prevented from flowing sequentially through the first mixing pathway and the second mixing pathway from the cartridges, and a second state, in which fluid components to be mixed are allowed to flow sequentially through the first mixing pathway and the second mixing pathway, at least a mixing rod is arranged in each of the first mixing pathway and the second mixing pathway to mix the fluid components flowing through the same.
[0009] Because in the first state of the mixing assembly the fluid components to be mixed are prevented from flowing sequentially through the first mixing pathway and the second mixing pathway from the cartridges, the fluid components can be safely stored in the cartridges. Therefore, the quality of the fluid components will not be deteriorated by contacting ambient air. Moreover, only in the second state of the mixing assembly, the fluid components can be mixed by the mixing rods when they flow through the mixing pathways. This enables the finally mixed product to be used or distributed directly after its discharging from the mixing head. This will also ensure that the quality of the finally mixed product will not be deteriorated by contacting ambient air. Moreover, defining the mixing pathways in the mixing assembly at different parallel planes will enable the whole mixer to be more compact and the lengths of the mixing pathways to be maximized, facilitating even mixing of the fluid components.
[0010] In an embodiment, the mixing assembly comprises a seat slidable in the body of the mixing head, the seat is provided with a basin part in which a first mixing member, a second mixing member and a discharge member are installable such that the first mixing pathway is defined between the first mixing member and the second mixing member and the second mixing pathway is defined between the second mixing member and the discharge member.
[0011] In an embodiment, each mixing rod has a central shaft and a plurality of petals extending radially outwards therefrom, longitudinally spaced from each other along the central shaft, and rotated relative to each other about the shaft by identical or different angles in alternate reverse spiral manner such that fluid components, when passing through them, will be mixed with each other.
[0012] In an embodiment, the first and / or second mixing pathway comprises two parallel first and / or second straight mixing pathway branches respectively extending in a lateral direction of the mixing assembly, and each of the mixing pathway branches is provided with the mixing rod therein.
[0013] In an embodiment, the first mixing member and the second mixing member are at least partially recessed on their facing sides such that the two parallel first straight mixing pathway branches are formed therebetween, the first mixing member is formed with a first straight middle ridge which is configured to protrude from the side of the first mixing member and be insertable into the second mixing member between the two first straight mixing pathway branches such that the two first mixing pathway branches are connected to each other at only one lateral end of the first mixing member, and an inlet opening is formed in the first mixing member at or adjacent to the other opposite lateral end of the first mixing member.
[0014] In an embodiment, the seat is also provided with at least two tubes protruding from the basin part and configured to receive the pressurized fluid components from the cartridges in the second state of the mixing assembly, and the inlet opening of the first mixing member is configured to be in fluid communication with the tubes of the seat.
[0015] In an embodiment, the two first straight mixing pathway branches have the same length such that the mixing rods arranged therein are substantially identical to each other in length.
[0016] In an embodiment, the second mixing member and the discharge member are at least partially recessed on their facing sides such that the two parallel second straight mixing pathway branches are formed therebetween, the second mixing member is formed with a second straight middle ridge which is configured to protrude from the side of the second mixing member and be insertable into the discharge member between the two second straight mixing pathway branches, an inlet opening is formed in the second mixing member aside the second straight middle ridge at one lateral end of the second mixing member, the two second mixing pathway branches are connected to each other at the opposing lateral end of the second mixing member and a barrier is formed adjacent to the inlet opening in the second mixing member such that one of the two second mixing pathway branches directly adjacent to the barrier is shorter than the other of the two second mixing pathway branches, and the fluid components to be mixed are able to flow from the longer second mixing pathway branch to the shorter second mixing pathway.
[0017] In an embodiment, the inlet opening of the second mixing member is longitudinally oriented towards a location of the first mixing pathway which is directly opposite to the inlet opening of the first mixing member apart by the first straight middle ridge.
[0018] In an embodiment, the discharge member is provided with a spray port configured to protrude from the body of the mixing head and in fluid communication with the second mixing pathway.
[0019] In an embodiment, a cover is installed in the body of the mixing head and is provided with a cantilever part to contact the discharge member of the mixing assembly, and the mixing assembly can be slid from the first state to the second state by pressing the cantilever part.
[0020] In an embodiment, the cantilever part is formed with several bulges spaced from each other, such that the cover is in contact with the discharge member via the bulges only.
[0021] In an embodiment, the mixing head is provided with a base releasably connected to the body longitudinally opposite to the cover, and configured to receive the cartridges.
[0022] In an embodiment, the mixer further comprises a cartridge receiving compartment releasably connected to the body of the mixing head, in which cartridge receiving compartment the at least two cartridges are releasably installable.
[0023] In an embodiment, the tubes of the seat are configured to contact the respective cartridges in the base such that in the second state of the mixing assembly the tubes of the seat are driven to longitudinally press the respective cartridges and thus the pressurized fluid components can be discharged from the cartridges into the tubes.
[0024] In an embodiment, the tubes of the seat are arranged side-by-side in the lateral direction of the mixing assembly.
[0025] In an embodiment, the mixer is configured to generate a hair dye by mixing two fluid components. Using the technical means as disclosed here, the mixer can be designed in a compact way and thus the fluid components, when flowing the mixing head of the mixer, can be automatically and more evenly mixed with each other. Besides, although the mixer is compact in shape, the length of the mixing pathway can be maximized in the mixing head such that the mixing effect can be improved. Moreover, as the mixing occurs in the interior of the mixing head, no odor discomforting a worker may be smelt during the mixing. Especially when the mixer is used a mixer for generating a hair dye, the hair dye discharged from the mixer can be directly distributed onto one's hairs, to avoid deterioration of the hair dye due to exposure to air.BRIEF DESCRIPTION OF THE DRAWINGS

[0036] A mixer for fluid components or fluid agents according to an embodiment of the present disclosure will be explained below. Here, the mixer as explained is used to mix two fluid components or fluid agents therein. However, it could be conceived by a person skilled in the art that the mixer as explained here can be used to mix three or more fluid components or fluid agents by revising the mixer in a reasonable way which is well-known in the art. Moreover, although the mixer will be explained here as a mixer for generating a hair dye through two fluid components or fluid agents thereof for example, the mixer according to the present disclosure can be used to generate any other composite fluid material which is formed by mixing at least two fluid components or fluid agents.
[0037] As shown by Fig. 1, the mixer 100 according to the embodiment of the present disclosure generally comprises a mixing head 3 configured to releasably receive two or more cartridges 4. In Fig. 1, only two cartridges 4 are shown side-by-side along a lateral direction of the mixer 100 for example. Each cartridge 4 is substantially cylinder-shaped, configured to store a pressurized fluid component or fluid agent for generating the hair dye therein, and provided with an outlet tube (invisible) protruding from an end of the cartridge 4. The cartridge 4 is configured such that when a resilient part around the outlet tube or the outlet tube itself is axially pressed, the pressurized fluid component or fluid agent will be sprayed out of the cartridge via the outlet tube. Therefore, the resilient part can be regarded as an activation part of the cartridge for selectively discharging the pressurized fluid component or fluid agent therefrom. In an alternative embodiment, the resilient part or the activation part of the cartridge can be the outlet tube itself. In this case, when the outlet tube is axially pressed, the pressurized fluid component or fluid agent will be sprayed out of the cartridge via the outlet tube. When the two cartridges 4 are connected to the mixing head 3 in place, their outlet tubes can be exposed in the mixing head 3.
[0038] Fig. 2 schematically illustrates the mixer 100 in an exploded and perspective view. As shown, the mixing head 3 generally comprises a body 1. The body 1 is formed or defined with a central hollow space in which a seat 37 is slidably receivable. As shown by Fig. 3, the central hollow space is surrounded by an inner wall 1b of the body 1. The body 1 is also formed with an outer wall 1a which is substantially spaced from and parallel to the inner wall 1b. The outer wall 1a of the body 1 is accessible by a user when the entire mixer 100 is assembled. The outer wall 1a is formed with a gripping zone 12 (see Fig. 1) on its exposure face; especially on its opposite faces respectively. For instance, the gripping zone 12 is defined by a rectangle-shaped wall part which is cut from the major portion of the wall 1a by a gap and is connected to the same at opposite points only. Besides, in the gripping zone 12, several (three, as shown) straight ridges are also formed to protrude from the respective face to facilitate the user gripping the mixing head 3. Besides, a first notch 1c and a second notch 1d are formed in the body 1 of the mixing head 3 such that the first notch 1c and the second notch 1d extend from an exposure part of the body 1 which connects the outer wall 1a and the inner wall 1b. The first notch 1c is configured to leave a space for containing a continent part of the mixing head 3 which will be explained below. The second notch 1d is configured to leave a space allowing movement of another continent part of the mixing head 3 which will be explained below.
[0039] According to the embodiment as shown, a base 2 of the mixing head 3 is connectable to, for example insertable into, the body 1 of the mixing head 3 longitudinally opposite to the seat 37. The inner wall 1b of the body 1 is longitudinally shorter than the outer wall 1a of the body 1. Therefore, as shown by Fig. 3, when the base 2 is inserted in place, it can be surrounded only by the outer wall 1a of the body 1. As an example, for the sake of aesthetic, the base 2 is configured such that when it is inserted into the body 1, it will not protrude longitudinally from the body 1.
[0040] As shown by Fig. 8, the base 2 is formed with two annular parts 22 which are spaced from each other. It is conceivable by a person skilled in the art that the base 2 is inversely shown in Figs. 2 and 8. Therefore, in Fig. 2, the two annular parts 22 are partially hidden. The two annular parts 22 are at a side of the base 2 which faces the cartridges when the cartridges 4 are connected to the mixing head 3. Each annular part 22 is formed with a partial circumferential slot 23 which is configured to releasably receive an end edge of a respective cartridge 4. As shown, the base 2 is formed with two opposite lugs 24, only one of which is visible in Fig. 2. Correspondingly, two opposite slots 11 are formed in the body 1 of the mixing head 3, especially in the gripping zone 12 of the body 1 such that when the base 2 is inserted in the bod 1, the two opposite lugs 24 can be releasably held in the two opposite slots 11 respectively. In this way, the base 2 can be secured in the body 1 in place. In an additional embodiment, the mixer may comprise a cartridge receiving compartment (not shown) which is releasably connected to the mixing head 3. For instance, the cartridge receiving compartment is configured to be partially insertable into the mixing head 3. The cartridge receiving compartment is substantially shaped as a double-hollow cylinder, especially a side-by-side double-hollow cylinder such that two cartridges 4 can be removably installed in the cartridge receiving compartment side-by-side. When the cartridge receiving compartment is inserted in the mixing head 3, the cartridges 4 in the cartridge receiving compartment can be naturally connected to the base 2 of the mixing head 3.
[0041] As shown by Figs. 2 and 3, the seat 37 is generally comprised of a basin part 373 and two tubes 371 which integrally protrude from the basin part 373. The basin part 373 of the seat 37 is profiled such that it is slidably installed in the central hollow space of the body 1. As shown by Fig. 4, the basin part 373 generally comprises a circumferential wall 3731 and a bottom wall 3732 integrally with and surrounded by the circumferential wall 3731. The two tubes 371 are spaced from each other by a distance which is identical to a distance between the outlet tubes of the cartridges. The seat 37, when received in the body 1, is slidable between a released state and a pressed state. In the released state, the tubes 371 of the seat 37 received in the body 1 are in slight contact with the resilient parts (i.e., the activation parts) of the cartridges respectively such that the tubes 371 coaxially align with the outlet tubes of the cartridges respectively. Here, the contact therebetween is not enough such that the resilient parts are pressed to discharge the pressurized fluid components or fluid agents. In the pressed state, the tubes 371 are driven to press the resilient parts of the cartridges. Each of the tubes 371 is defined with a channel 31 in its interior. As shown by Fig. 4, the channels 31 are in fluid communication with each other by a groove 39 formed in the bottom wall 3732. Except for the groove 39, the bottom wall 3732 is planar. Therefore, after the cartridges 4 are connected to the mixing head 3, the channels 31 defined by the tubes 371 of the seat 37 are in fluid communication with the outlet tubes of the cartridges respectively in the second state of the body 1 only.
[0042] As shown by Figs. 2 and 5, a first mixing member 341 comprises a bed plate 3415, a first circumferential edge 3413 surrounding the bed plate, and a second circumferential edge 3414 radially external to the first circumferential edge 3413. A circumferential recess is thus formed between the first circumferential edge 3413 and the second circumferential edge 3414 to receive a part of a second mixing member 342 that will be explained below and partially shown by Fig. 3.
[0043] The bed plate 3415 has a planar side to contact the bottom wall 3732 of seat 37 when the first mixing member 341 is securely received in the basin part 373. The other side of the bed plate 3415 opposing the planar side is formed with a first straight middle ridge 3412 extending substantially along a lateral direction of the bed plate 3415. As shown by Fig. 3, the first straight middle ridge 3412 is higher than the first circumferential edge 3413 which is higher than the second circumferential edge 3414 when the first mixing member 341 is securely received in the basin part 373. The first straight middle ridge 3412 is configured to define a first mixing pathway between the bed plate 3415 and the second mixing member 342, especially at the other side of the bed plate 3415. The first mixing pathway has two first straight mixing pathway branches parallel to each other and connected with each other at or adjacent to one lateral end of the bed plate 3415 only. It can be seen that the first mixing pathway is in a plane substantially perpendicular to a direction along which the tubes 371 or the channels 31 of the seat 37 can be moved when the first mixing member 341 is securely received in the basin part 373 of the seat 37. The circumferential wall 3731 in its radial inner side is formed with a step 3734 such that when the first mixing member 341 is securely received in the basin part 373 of the seat, the first mixing member 341 will not extend beyond the step 3734. A notch 3733 is formed in the circumferential wall 3731 of the basin part 373 above the step 3737, as shown by Fig. 4.
[0044] An inlet opening 3411 is formed in the bed plate 3415, especially at or adjacent to the opposing lateral end of the bed plate 3415 where the two first mixing pathway branches are separated from each other by a barrier integrally formed below the first straight middle ridge 3412. The inlet opening 3411 is configure such that when the first mixing member 341 is securely received in the basin part 373 of the seat 37, the inlet opening 3411 will be in fluid communication with the groove 39 of the basin part 373. It can be seen that the inlet opening 3411 is substantially laterally opposite to the end of the bed plate 3415 where the two first mixing pathway branches are connected to each other. This will enable the first mixing pathway to extend between the first and second mixing members 341 and 342 by a maximized length. Therefore, when the entire mixer is assembled in place and the seat 37 is in its pressed state, the discharged fluid components or fluid agents of the cartridges will flow through the groove 39, via the inlet opening 3411, finally into the first mixing pathway in which the fluid components or fluid agents, after being deflected by the barrier below the first middle ridge 3412, will flow along a direction represented by a dotted arrow as shown by Fig. 5.
[0045] The second mixing member 342 as shown by Fig. 6 can be placed over the first mixing member 341 in the basin part 373 of the seat 37 such that a step 3427 formed on an outer wall of the second mixing member 342 is able to substantially flush with the step 3734 of the basin part 373. The second mixing member 342 has a side which faces the first mixing member 341 when the second mixing member 342 is placed over the first mixing member 341 in the basin part 373. This side invisible in Fig. 6 can be formed in a manner substantially complementary to the side of the bed plate 3415 of the first mixing member 341 where its first mixing pathway is defined. As shown by Fig. 3, the side of the second mixing member 342 is formed with a straight slot 3421 into which the first straight middle ridge 3412 of the first mixing member 341 can be inserted such that the two first mixing pathway branches of the first mixing pathway can be fluidly isolated from each other except for at or adjacent to the lateral end of the bed plate 3415 where they are connected with each other. Besides, a lower circumferential edge of the second mixing member 342 is configured to be insertable into the circumferential recess of the first mixing member 341 to avoid undesired fluid leakage. It can be seen that each first mixing pathway branch has a substantially circular cross-section. Each first mixing pathway branch is sized such that a mixing rod 36 can be placed in the first mixing pathway branch. Therefore, two mixing rods 36 can be placed in the first mixing pathway between the first mixing member 341 and the second mixing member 342. Each mixing rod 36 has a length substantially equal to that of the respective first mixing pathway branch. As shown by Figs. 2 and 3, each mixing rod 36 has a plurality of petals which extend radially outwards from a central shaft of the mixing rod 36. Those petals are angled relative to the central shaft, longitudinally spaced from each other along the central shaft, and rotated relative to each other about the central shaft by identical or different angles in alternate reverse spiral manner such that they are distributed in an alternate reverse spiral or other suitable regular or even irregular manner. For example, the mixing rods 36 are supported between the first and second mixing members 341 and 342 by the petals. When the pressurized fluid components or fluid agents entering the inlet opening 3411 flow between the petals of the mixing rods 36 in the first mixing pathway, the fluid components or fluid agents will be continuously stirred or mixed by the petals of the mixing rods 36 although the mixing rods may be stationary in the first mixing pathway.
[0046] As shown by Figs. 2 and 3, a discharge member 38 can be installed at least partially in the seat 37 such that the discharge member 38 is placed over the second mixing member 342. When the discharge member 38 is placed over the second mixing member 342, a lower circumferential edge of the discharge member 38 can be seated on the steps 3427 and 3734 of the second mixing member 342 and the basin part 373 flushing with each other. A side of the second mixing member 342 opposing the first mixing member 341 and a side of the discharge member 38 facing the second mixing member 342 can be recessed such that a second mixing pathway can be defined between the second mixing member 342 and the discharge member 38. The second mixing pathway is in a plane also substantially perpendicular to the direction along which the tubes 371 or the channels 31 of the seat 37 can be moved when the first mixing member 341 is securely received in the basin part 373 of the seat 37. In order to define the second mixing pathway, a second straight middle ridge 3422 is formed on the side of the second mixing member 342. The discharge member 38 is formed with a straight slot 381 on its side facing the second mixing member 342, such that when the discharge member 38 is placed over the second mixing member 342, the second straight middle ridge 3422 can be partially inserted into the straight slot 381 in an interference-fit manner. The side of the discharge member 38 where the straight slot 381 is formed is surrounded by a circumferential wall 382 of the discharge member 38. The circumferential wall 382 of the discharge member 38 is configured to be sleeved about a part of the outer wall of the second mixing member 342 above the stelp 3427 as shown by Fig. 6, when the discharge member 38 is placed over the second mixing member 342.
[0047] As shown by Fig. 6, an inlet opening 3423 is formed in the side of the second mixing member 342 aside the second straight middle ridge 3422. When the second mixing member 342 is placed over the first mixing member 341, the inlet opening 3423 is longitudinally oriented towards a location of the first mixing pathway between the first mixing member 341 and the second mixing member 342 which location is directly opposite to the inlet opening 3411 of the first mixing pathway apart by the first straight middle ridge 3412. A barrier 3424 is formed on the side of the second mixing member 342 immediately adjacent to the inlet opening 3423. A notch 3425 is formed in the part of the outer wall of the second mixing member 342 above the step 3427. As an example, 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. As shown, 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. Unlike the first mixing pathway, due to the existence of the barrier 3424, 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. It can be seen that 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. In this case, 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. During this, 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.
[0048] As shown by Fig. 8, the discharge member 38 is formed with a spray port 32 which is for example in the form of a tube. When the discharge member 38 is placed over the second mixing member 342, 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.
[0049] According to the embodiment of the present disclosure, 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. According to the embodiment of the present disclosure, 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.
[0050] It is conceivable by a person skilled in the art that 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. In this case, 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.
[0051] As shown by Fig. 2, 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. In an alternative embodiment, 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.
[0052] Because in 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. Especially, 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. In the assembled mixer, when the cantilever part 51 or the button part 52 is not pressed, 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. With the cantilever part 51 or the button part 52 being pressed, 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. When the cantilever part 51 or the button part 52 is released, 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.
[0053] It is conceivable by a person skilled in the art that depending on actual requirements, 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.
[0054] Although some specific embodiments and / or examples of the present disclosure are described here, they are given for illustrative purposes only and cannot be deemed to constrain the scope of the present disclosure in any way. Furthermore, it should be understood by a skilled person in the art that the embodiments and / or examples described here can be combined with each other. Without departing from the spirit and scope of the present disclosure, various replacements, modifications, and alternations can be carried out.
