Description

Technical Field

[0001] The invention relates to a hair dye mixing and discharging device. Background Art

[0002] In hair dyeing, it is often necessary to mix two hair dyes with different ingredients in a 1:1 ratio. Currently, the only way is to manually squeeze the two hair dyes into a measuring cup separately and then mix them in equal amounts. This method is inefficient and has poor mixing effect.

[0003] In the related art, some hair dye containers are equipped with multiple liquid discharge pump heads on one product, which simultaneously squeeze the nozzle membrane bags containing different hair dyes to drive different liquids to be discharged together. The hair dye container with this structure cannot achieve the same flow rate from different liquid discharge pump heads, and the uneven discharge causes unstable efficacy after product mixing. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, one of the objectives of the present invention is to provide a hair dye mixing and discharging device that can achieve synchronous discharge of two hair dyes in a ratio of substantially 1:1.

[0005] According to an embodiment of the present invention, a hair dye mixing and discharging device comprises: a soft gel bottle body and a mounting base mounted at the bottle mouth of the soft gel bottle body, a closed chamber is defined between the mounting base and the soft gel bottle body, the mounting base is provided with two connecting pipes arranged in a vertical direction, the lower ends of the connecting pipes are connected to a suction nozzle bag located in the closed chamber, the hair dyes in the two suction nozzle bags are different, the mounting base is connected to a valve body, two independent fluid chambers are provided in the valve body, valve cores are rotatably provided in the fluid chambers, a strong magnetic component is provided between the two valve cores to keep the two valve cores rotating synchronously at the same angle, and the valve core is arranged around its rotation axis. Three valve flaps are provided, and a unit cavity is defined between two adjacent valve flaps and the inner wall of the fluid chamber. The lower parts of the two fluid chambers are respectively connected to the upper ends of the two connecting pipes, and the upper parts of the two fluid chambers are connected to liquid outlet pipes. A mixing pipe for merging the liquids discharged from all the liquid outlet pipes is provided on the mounting seat; when the soft plastic bottle body is squeezed to compress the gas in the closed chamber, the liquid in the two nozzle bags respectively enters one of the unit cavities of the corresponding fluid chamber to drive the two valve cores to rotate synchronously, and the other unit cavity of the fluid chamber can be connected to the liquid outlet pipe to output the liquid to the mixing pipe.

[0006] The hair dye mixing and discharging device according to the embodiment of the present invention has at least the following beneficial effects:

[0007] When two hair dyes need to be mixed, the user squeezes the soft gel bottle to compress the gas in the closed chamber. The compressed gas produces a uniform squeezing force on the two nozzle bags. The hair dyes in the two nozzle bags are squeezed out respectively to flow into two independent fluid chambers. The two hair dye fluids respectively drive the valve flaps of the corresponding valve cores to rotate. Due to the presence of strong magnetic components, the two valve cores can rotate synchronously to produce the same angular displacement, thereby ensuring that the flow rate discharged from the two liquid outlet pipes is basically consistent. Finally, the two discharged hair dyes enter the mixing tube to merge, thereby quickly achieving a 1:1 ratio of synchronously discharged hair dyes and mixing, ensuring that the efficacy of the hair dye product after mixing is more stable.

For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0035] Reference Figures 1 to 6 , a hair dye mixing and discharging device of the present invention comprises: a soft plastic bottle body 100 and a mounting base 200 mounted at the bottle mouth of the soft plastic bottle body 100, a closed chamber 110 is defined between the mounting base 200 and the soft plastic bottle body 100, the mounting base 200 is provided with two connecting pipes 210 arranged in a vertical direction, the lower end of the connecting pipe 210 is connected to a suction nozzle bag 300 located in the closed chamber 110, the hair dyes in the two suction nozzle bags 300 are different, the mounting base 200 is connected to a valve body 400, the valve body 400 is provided with two independent fluid chambers 410, the fluid chamber 410 can be rotatably provided with a valve core 420, a strong magnetic component 500 is provided between the two valve cores 420 to keep the two rotating synchronously at the same angle, and the valve core 420 is provided with a rotating shaft around its rotation axis. There are three valve flaps 430, and a unit cavity 411 is defined between two adjacent valve flaps 430 and the inner wall of the fluid chamber 410. The lower parts of the two fluid chambers 410 are respectively connected to the upper ends of the two connecting pipes 210. The upper parts of the two fluid chambers 410 are connected to the liquid outlet pipes 440. The mounting seat 200 is provided with a mixing pipe 610 for merging the liquids discharged from all the liquid outlet pipes 440. When the soft plastic bottle body 100 is squeezed to compress the gas in the closed chamber 110, the liquid in the two nozzle bags 300 respectively enters one of the unit cavities 411 of the corresponding fluid chamber 410 to drive the two valve cores 420 to rotate synchronously, and the other unit cavity 411 of the fluid chamber 410 can be connected to the liquid outlet pipe 440 to output the liquid to the mixing pipe 610.

[0036] When two hair dyes need to be mixed, the user squeezes the soft gel bottle 100 to compress the gas in the closed chamber 110. The compressed gas produces a uniform squeezing force on the two nozzle bags 300. The hair dyes in the two nozzle bags 300 are squeezed out respectively to flow into two independent fluid chambers 410. The two hair dye fluids respectively drive the valve flap 430 of the corresponding valve core 420 to rotate. Due to the presence of the strong magnetic component 500, the two valve cores 420 can rotate synchronously to produce the same angular displacement, thereby ensuring that the flow rate discharged from the two liquid outlet pipes 440 is basically consistent. Finally, the two discharged hair dyes enter the mixing tube 610 to merge, thereby quickly achieving a 1:1 ratio of synchronous discharge and mixing of the hair dyes, ensuring that the efficacy of the hair dye product after mixing is more stable.

[0037] Specifically, see Figure 3 Three unit cavities 411 are defined between the three valve flaps 430 and the inner wall of the fluid chamber 410. When the fluid in the nozzle bag 300 enters one of the unit cavities 411 of the fluid chamber 410 and fills the unit cavity 411, the fluid pushes the valve core 420 to rotate to another unit cavity 411 to align with the fluid output by the nozzle bag 300, and the unit cavity 411 is filled and pushed to rotate again. During this process, when the unit cavity 411 filled with fluid rotates to align with the liquid outlet pipe 440, part of the fluid is discharged into the liquid outlet pipe 440. When the unit cavity 411 that has discharged the fluid is aligned with the upper end of the connecting pipe 210 again, the unit cavity 411 can be filled again, thereby repeatedly achieving continuous and uniform release of the hair dye.

[0038] See also Figure 2 and Figure 4 In some embodiments of the present invention, the fluid chamber 410 is in a horizontal cylindrical shape, and a partition is provided in the valve body 400 to separate the two fluid chambers 410. The opposite side walls of the partition are formed with a rotating shaft 460 coaxial with the fluid chamber 410. The valve core 420 is provided with a sleeve portion 421 passing through the rotating shaft 460. The valve flap 430 is formed on the outer peripheral wall of the sleeve portion 421 and extends radially outward to abut against the fluid chamber 41. 0, the strong magnetic component 500 includes a first magnet 510 provided on one of the valve cores 420 and a second magnet 520 provided on the other valve core 420 and attracted to the first magnet 510, and a first liquid outlet 470 is provided at the lower portion of the fluid chamber 410, which is connected to the upper end of the connecting tube 210 and offset from the rotating shaft 460, so that the fluid flowing into the fluid chamber 410 from the first liquid outlet 470 can drive the valve flap 430 to rotate.

[0039] It should be noted that in order to ensure that the two hair dyes can output the same flow rate independently, the two fluid chambers 410 need to be isolated from each other. If a connecting shaft is used to connect the two valve cores 420 to ensure synchronous rotation, it needs to be passed through a partition. The connecting shaft rotates relative to the partition, and the sealing between the connecting shaft and the partition must be permanently ensured, which can easily lead to reduced reliability. The strong magnetic assembly 500 composed of the first magnet 510 and the second magnet 520 solves this problem well. When one valve core 420 rotates at any clockwise angle, the other valve core 420 also follows and rotates at the same angle. Figure 3 , wherein the direction of travel of the fluid discharged from the first liquid outlet 470 is offset from the axis of the rotating shaft 460, that is, the fluid can act on a valve flap 430 and generate torque on the valve core 420, so that the user can manually squeeze the soft gel bottle body 100 to drive the two valve cores 420 to rotate synchronously at an equal angular velocity, and finally achieve the output and mixing of the two hair dyes in equal amounts, thereby ensuring the efficacy of the mixed hair dye products.

[0040] See also Figure 3 and Figure 6 In some embodiments of the present invention, the valve flap 430 is an arc-shaped arch plate formed on the outer peripheral wall of the sleeve portion 421. The arc-shaped arch plate extends along the length direction of the sleeve portion 421. A cylindrical cavity is formed between the arc-shaped arch plate and the sleeve portion 421, which is beneficial to reducing the mass and rotational inertia of the valve core 420, so that it rotates faster under the same torque and increases the liquid discharge speed. There are arc transitions between adjacent arc arch plates and between the arc arch plates and the sleeve portion 421. The lower part of the valve body 400 is provided with an outer sleeve 480 that is sleeved on the upper part of the connecting pipe 210. The axis of the outer sleeve 480 is orthogonal to the axis of the rotating shaft 460. The first liquid outlet 470 passes through the outer sleeve 480 on one side of the axis of the rotating shaft 460 to act on one of the arc arch plates. The first liquid outlet 470 of the above structure enables the fluid entering the fluid chamber 410 to act on the same valve disc 430 in the same clockwise direction, reducing interference with the rotation direction of the valve core 420. Moreover, the arc transitions between adjacent arc arch plates and between the arc arch plates and the sleeve portion 421 can also reduce turbulence and reduce working noise.

[0041] See also Figure 9In some embodiments of the present invention, the rotating shaft 460 is a sleeve that is inserted into the sleeve portion 421, and the first magnet 510 and the second magnet 520 are cylindrical magnets that are tightly inserted into the corresponding sleeves. It is understandable that when the first magnet 510 and the second magnet 520 are offset relative to the rotating shaft 460, the first magnet 510 and the second magnet 520 each exert a gravitational torque on the corresponding valve core 420, thereby causing a dynamic imbalance when the fluid drives the valve core 420 to rotate, affecting the uniformity of the angular velocity of the valve core 420 during rotation and causing the valve core 420 to vibrate. This problem can be solved by configuring the rotating shaft 460 as a sleeve and configuring the first magnet 510 and the second magnet 520 as the aforementioned cylindrical magnets.

[0042] In some embodiments of the present invention, the liquid outlet pipes 440 corresponding to the two fluid chambers 410 are each provided with a Hall effect sensor for detecting the flow of the fluid, the Hall effect sensor is electrically connected to a control module, and the control module is electrically connected to a prompt module. It should be noted that if a problem occurs with the strong magnetic component 500 and the two valve cores 420 cannot rotate synchronously, the ratio of the two hair dyes discharged will not be close to 1:1, thereby affecting the efficacy of the hair dye product after mixing. At this time, when the two Hall effects sensors detect that the flow rate of the fluid has a large deviation from the set range, the control module can control the prompt module to operate, and the prompt module can light up or play audio to remind the user to replace the strong magnetic component 500 or the entire valve core 420.

[0043] See also Figures 2 to 4In some embodiments of the present invention, the mounting seat 200 is provided with a circle of annular wall plates 220, on which a cover shell 600 with a downward opening is mounted, and the mixing liquid tube 610 is provided in the middle position of the top of the cover shell 600. The cover shell 600, the annular wall plates 220 and the mounting seat 200 define a mounting cavity for accommodating the valve body 400. The upper portion of the valve body 400 is provided with a fluid tube that is movably passed through the mixing liquid tube 610, and the two liquid outlet pipes 440 are both formed inside the fluid tube. The interior of the connecting pipe 210 is provided with a channel 230 that is wide at the top and narrow at the bottom. The lower portion of the valve body 400 is provided with an outer sleeve 480 that is sleeved on the upper portion of the connecting pipe 210 and a plug-in column portion 481 located within the outer sleeve 480. The valve body 400 can be raised and lowered relative to the mounting seat 200 so that the plug-in column portion 481 opens or closes the narrow portion of the channel 230. It is understood that when the valve body 400 is lowered relative to the mounting base 200 so that the plug-in portion 481 closes the narrow portion of the passage 230, the nozzle of the nozzle bag 300 is blocked, preventing the hair dye from being discharged. This prevents the user from accidentally discharging the hair dye when grasping the soft plastic bottle 100. Therefore, when a user wishes to use the hair dye mixing and discharging device of the present invention, they must first raise the valve body 400 relative to the mounting base 200 so that the plug-in portion 481 opens the narrow portion of the passage 230.

[0044] See also Figure 4 、 Figure 5 and Figure 6In some embodiments of the present invention, the inner circumferential wall of the housing 600 is provided with an annular member 620, and the annular member 620 is rotatably provided on the outer circumferential wall of the annular wall plate 220, and the annular wall plate 220 is provided with a vertical guide groove 221 provided in the vertical direction, and the side wall of the annular member 620 is provided with a spiral guide groove 621, and the valve body 400 has a guide column 490 located in the vertical guide groove 221 and passing through the spiral guide groove 621, and the annular member 620 and the housing The shell 600 rotates relative to the mounting seat 200 to make the valve body 400 rise relative to the mounting seat 200 and make the plug-in column 481 open the channel 230, or to make the valve body 400 fall relative to the mounting seat 200 and make the plug-in column 481 close the channel 230. A plurality of serrated grooves 222 are distributed around the upper end surface of the annular wall plate 220, and a positioning buckle portion 622 is provided on the inner wall of the annular member 620 to be elastically engaged with the serrated groove 222. It should be noted that when opening or closing the channel 230, the user grasps the soft gel bottle body 100 with one hand and the cover 600 with the other hand, and then drives the soft gel bottle body 100 and the mounting base 200 to rotate relative to the cover 600. At this time, the guide post 490 moves along the spiral guide groove 621. The guide post 490 can only move up and down relative to the mounting base 200 under the limitation of the vertical guide groove 221. In the absence of torsion, the valve body 400 cannot move up and down, and the positioning buckle portion 622 and the serrated groove 222 cooperate to keep the valve body 400 stable after the movement. Among them, when the cover 600 and the annular member 620 rotate relative to the mounting base 200, the positioning buckle portion 622 can elastically move in and out of each serrated groove 222 until the guide post 490 moves to the upper end or lower end of the spiral guide groove 621.

[0045] See also Figure 2 and Figure 4In some embodiments of the present invention, a cover 700 is snap-connected to the cover shell 600, and an inner top wall of the cover 700 is provided with a downwardly extending limit plug-in 710. When the valve body 400 descends relative to the mounting seat 200 and causes the plug-in portion 481 to close the channel 230, the cover 700 is snap-connected to the cover shell 600 so that the limit plug-in 710 is fully inserted into the mixing tube 610. When the valve body 400 rises relative to the mounting seat 200 and causes the plug-in portion 481 to open the channel 230, the upper end of the fluid tube presses against the limit plug-in 710 to prevent the cover 700 from being snap-connected to the cover shell 600. It should be noted that when the soft gel bottle body 100 rotates relative to the cover shell 600 so that the guide column 490 moves to the upper end of the spiral guide groove 621, the valve body 400 moves upward, the column portion 481 opens the channel 230, and the upper end of the fluid tube moves upward relative to the mixing liquid tube 610. At this time, if the cover 700 is directly used to snap on the cover shell 600, the limit plug-in 710 is inserted downward along the mixing liquid tube 610 and is supported by the upper end of the fluid tube, and the cover 700 cannot be installed on the cover shell 600, thereby reminding the user that the positions of the valve body 400 and the column portion 481 have not been completely reset, preventing fluid leakage.

[0046] See also Figure 7 and Figure 8In some embodiments of the present invention, the mounting seat 200 is provided with a gas pipe 240 arranged in a vertical direction and capable of connecting the closed chamber 110 with the outside world, and a gravity ball 250 is movably raised and lowered in the gas pipe 240, and the upper and lower ends of the gas pipe 240 respectively have an upper necking portion 241 and a lower necking portion 242 that can be sealed with the gravity ball 250, and a side wall of the gas pipe 240 is provided with a notch portion 243; when the soft plastic bottle body 100 is placed upright, the gravity ball 250 is in sealing contact with the lower necking portion 242 so that the notch portion 243 can connect the upper necking portion 241 with the closed chamber 110; when the soft plastic bottle body 100 is inverted, the gravity ball 250 is in sealing contact with the upper necking portion 241 so that the notch portion 243 is isolated from the upper necking portion 241. It is understandable that when the hair dye mixing and discharging device of the present invention is used normally, the soft plastic bottle body 100 needs to be inverted, that is, the soft plastic bottle body 100 is located above the mounting seat 200, the mixing tube 610 is facing downward, and the gravity ball 250 contacts the upper constricted portion 241 due to its own gravity. At this time, the closed chamber 110 is in a completely sealed state, and the user squeezes the soft plastic bottle body 100 to compress the gas in the closed chamber 110, thereby discharging the fluid in the nozzle bag 300. When the soft gel bottle body 100 is placed upright, that is, the soft gel bottle body 100 is located below the mounting seat 200, the mixing tube 610 is facing upward, and the gravity ball 250 contacts the lower necked portion 242 under the action of its own gravity. At this time, the closed chamber 110 can be connected to the outside air. When the user squeezes the soft gel bottle body 100, the gas can be discharged after passing through the notch portion 243, the gas pipe 240 and the upper necked portion 241 in sequence. Moreover, when the gas enters the gas pipe 240 from the notch portion 243, it can also exert pressure to keep the gravity ball 250 against the lower necked portion 242.

[0047] See also Figure 9 and Figure 10In some embodiments of the present invention, the valve body 400 has a horizontally placed cylindrical member 401, the partition is formed in the middle of the cylindrical member 401, and sealing end covers 402 are respectively installed at both ends of the cylindrical member 401. The sleeve portion 421 of at least one of the valve cores 420 is provided with a pivot portion 422 that passes through the corresponding sealing end cover 402 at one end away from the partition, and a sealing ring 403 is provided between the pivot portion 422 and the sealing end cover 402. The end of the pivot portion 422 extending out of the sealing end cover 402 is connected to a damping disk 404, and a damping adjustment mechanism 800 is provided between the mounting seat 200 and the damping disk 404, and / or a brake mechanism 900 is provided between the mounting seat 200 and the damping disk 404. It is understandable that when the user squeezes the soft-gel bottle 100 too hard, the valve core 420 maintains inertial rotation for a long time, resulting in the inability to stop the fluid discharge in time, thereby causing waste of hair dye. For this reason, by providing a damping adjustment mechanism 800, the waste of hair dye can be greatly reduced, and the force of squeezing the hair dye can also be adjusted, thereby adjusting the feel of use. In addition, when the valve body 400 rises relative to the mounting seat 200 and the plug-in column 481 opens the channel 230, it is easy to squeeze the soft-gel bottle 100 uncontrollably during the inversion process of the soft-gel bottle 100, causing the fluid to be accidentally discharged. The brake mechanism 900 can be used to lock the damping disc 404 in advance to prevent the valve core 420 from rotating, playing a multiple insurance role. Before squeezing out the hair dye, the brake mechanism 900 needs to be used to unlock the valve core 420.

[0048] Specifically, see Figure 10 In some embodiments, the damping disk 404 is made of a magnetic conductive material, and the damping adjustment mechanism 800 includes a rotating arm 810 rotatably arranged on the mounting base 200, and the rotating arm 810 has two clamping plates 820 respectively located on both sides of the damping disk 404 and parallel to each other, and one of the clamping plates 820 facing the damping disk 404 is provided with a plurality of third magnets 830 distributed along the length direction of the rotating arm 810, and the other clamping plate 820 facing the damping disk 404 is provided with a plurality of fourth magnets 840 corresponding to the third magnets 830 one by one. The magnetic poles of the third magnet 830 and the fourth magnet 840 are opposite, and the rotating arm 810 is connected to a first motor 850 that drives it to rotate. The first motor 850 drives the rotating arm 810 to rotate to adjust the number of the third magnets 830 and the fourth magnet 840 located on both sides of the damping disk 404, thereby adjusting the magnitude of the damping force.

[0049] See also Figure 9In some embodiments, a magnetic member is provided on the damping disc 404, and a friction pad 910 is provided on the side wall of the damping disc 404. A brake disc 920 that can move close to or away from the friction pad 910 is slidably provided on the mounting seat 200, and the brake disc 920 is connected to a spring member 930 that drives it to abut against the friction pad 910. An electromagnetic coil 940 is also provided on the mounting seat 200. When the electromagnetic coil 940 is energized, the magnetic member on the damping disc 404 is magnetically attracted to compress the spring member 930, and the valve core 420 can rotate freely. When the electromagnetic coil 940 is de-energized, the spring member 930 drives the brake disc 920 to abut against the friction pad 910, and the valve core 420 cannot rotate. The electromagnetic coil 940 is electrically connected to a switch that controls its power on and off. The switch is provided on the outer wall of the mounting seat 200 for user convenience.
