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 and then mix them in equal amounts. This method is inefficient and has a 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 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 of the product after mixing. Summary of the invention

The two hair dye fluids respectively drive the valve flaps of the corresponding valve cores to rotate. Due to the presence of the strong magnetic component, 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.

[0035] Reference Figures 1 to 6 The present invention discloses a hair dye mixing and discharging device, comprising: a soft gel bottle body 100 and a mounting seat 200 mounted at the bottle mouth of the soft gel bottle body 100, wherein a closed chamber 110 is defined between the mounting seat 200 and the soft gel bottle body 100, wherein the mounting seat 200 is provided with two connecting pipes 210 arranged in a vertical direction, wherein the lower end of the connecting pipe 210 is connected with a nozzle bag 300 located in the closed chamber 110, wherein the hair dyes in the two nozzle bags 300 are different, wherein the mounting seat 200 is connected with a valve body 400, wherein the valve body 400 is provided with two fluid chambers 410 which are independent of each other, wherein valve cores 420 are rotatably arranged in the fluid chambers 410, wherein a strong magnetic component 500 is provided between the two valve cores 420 to keep the two valve cores 420 rotating synchronously at the same angle, wherein the valve core 420 is provided with a 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, and the upper parts of the two fluid chambers 410 are both connected to 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 gel bottle body 100 is squeezed to compress the gas in the closed chamber 110, the liquid in the two nozzle bags 300 respectively enters into 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 the 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 exerts a uniform squeezing force on the two nozzle bags 300. The hair dyes in the two nozzle bags 300 are squeezed out to flow into two independent fluid chambers 410. The two hair dye fluids drive the valve flaps 430 of the corresponding valve cores 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 rates discharged from the two liquid outlet pipes 440 are basically consistent. Finally, the two discharged hair dyes enter the mixing tube 610 to merge, thereby quickly achieving a 1:1 ratio of synchronously discharged hair dyes and mixing them, 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 cavities 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. In 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, the valve body 400 is provided with a partition 450 for separating the two fluid chambers 410, the two opposite side walls of the partition 450 are formed with a rotating shaft 460 coaxial with the fluid chamber 410, the valve core 420 is provided with a sleeve portion 421 penetrating the rotating shaft 460, the valve flap 430 is formed on the outer peripheral wall of the sleeve portion 421 and radially extends outward to abut against the fluid chamber The inner wall of the chamber 410, the strong magnetic component 500 includes a first magnet 510 arranged on one of the valve cores 420 and a second magnet 520 arranged on the other valve core 420 and attracted to the first magnet 510, and the lower part of the fluid chamber 410 is provided with a first liquid outlet 470 connected to the upper end of the connecting pipe 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 that the two rotate synchronously, it needs to be penetrated through the partition 450. The connecting shaft rotates relative to the partition 450. The sealing between the connecting shaft and the partition 450 must be permanently ensured, which easily leads to reduced reliability. The strong magnetic component 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 to generate torque on the valve core 420, so that the user can manually squeeze the soft gel bottle 100 to drive the two valve cores 420 to rotate synchronously at an equal angular velocity, and finally achieve equal output and mixing of the two hair dyes, thereby ensuring the efficacy of the hair dye products after mixing.

[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, and 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 moment of 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 which 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 allows the fluid entering the fluid chamber 410 to act on the same valve disc 430 in the same clockwise direction, thereby 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 reduce turbulence and reduce working noise.

[0041] See also Fig. 9In some embodiments of the present invention, the rotating shaft 460 is a sleeve inserted into the sleeve portion 421, and the first magnet 510 and the second magnet 520 are cylindrical magnets tightly inserted into the corresponding sleeves. It can be understood 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 have a gravity 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 when rotating and causing the valve core 420 to shake. This problem can be solved by setting the rotating shaft 460 as a sleeve and setting the first magnet 510 and the second magnet 520 as the above-mentioned cylindrical magnets.

[0042] In some embodiments of the present invention, the liquid outlet pipes 440 corresponding to the two fluid chambers 410 are both provided with Hall sensors for detecting the flow of the fluid, the Hall sensors are electrically connected to a control module, and the control module is electrically connected to a prompt module. It should be noted that if there is a problem 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 sensors detect that the flow of the fluid has a large deviation from the set range, the control module can control the prompt module to work, and the prompt module can be in the form of lighting or audio playback, so as 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, and a cover shell 600 with an opening facing downward is installed on the annular wall plate 220, and the mixing tube 610 is arranged at the middle position of the top of the cover shell 600, and the cover shell 600, the annular wall plate 220 and the mounting seat 200 define a mounting cavity for accommodating the valve body 400, and the upper part of the valve body 400 is provided with a fluid tube movably arranged in the mixing tube 610, and the two liquid outlet pipes 440 are both formed in the fluid tube, and the interior of the connecting pipe 210 is provided with a channel 230 that is wide at the top and narrow at the bottom, and the lower part of the valve body 400 is provided with an outer sleeve 480 sleeved on the upper part of the connecting pipe 210 and a plug-in column part 481 located in the outer sleeve 480, and the valve body 400 can be lifted and moved relative to the mounting seat 200 so that the plug-in column part 481 opens or closes the narrow part of the channel 230. It is understandable that when the valve body 400 is lowered relative to the mounting seat 200 so that the plug-in column 481 closes the narrow portion of the channel 230, the nozzle of the nozzle bag 300 is blocked and the hair dye cannot be discharged, thereby preventing the user from accidentally discharging the hair dye when grabbing the soft plastic bottle 100. Therefore, when the user wants to use the hair dye mixing and discharging device of the present invention, the valve body 400 needs to be raised relative to the mounting seat 200 so that the plug-in column 481 opens the narrow portion of the channel 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 arranged 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 arranged along 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 penetrating the spiral guide groove 621, and the annular member 620 and the housing The shell 600 rotates relative to the mounting seat 200, so that the valve body 400 rises relative to the mounting seat 200 and the plug-in column portion 481 opens the channel 230, or the valve body 400 descends relative to the mounting seat 200 and the plug-in column portion 481 closes the channel 230. A plurality of serrated grooves 222 are distributed circumferentially on the upper end surface of the annular wall plate 220, and the inner wall of the annular member 620 is provided with a positioning buckle portion 622 elastically snapped into the serrated groove 222. It should be noted that when opening or closing the channel 230, the user holds 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 seat 200 to rotate relative to the cover 600. At this time, the guide column 490 moves along the spiral guide groove 621. The guide column 490 only moves up and down relative to the mounting seat 200 under the limitation of the vertical guide groove 221. In the absence of torque, the valve body 400 cannot move up and down, and the positioning buckle part 622 and the serrated groove 222 cooperate to keep the valve body 400 stable after the lifting and moving. Among them, when the cover 600 and the ring part 620 rotate relative to the mounting seat 200, the positioning buckle part 622 can elastically move in and out of each serrated groove 222 until the guide column 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 a downwardly extending limit plug-in 710 is provided on the inner top wall of the cover shell 700. When the valve body 400 descends relative to the mounting seat 200 and the plug-in column 481 closes the channel 230, the cover 700 is snap-connected to the cover shell 600 so that the limit plug-in 710 is completely inserted into the mixing tube 610. When the valve body 400 rises relative to the mounting seat 200 and the plug-in column 481 opens 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 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 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 position of the valve body 400 and the column portion 481 has not been completely reset, thereby preventing fluid leakage.

[0046] See also Figure 7 and Figure 8In some embodiments of the present invention, a gas pipeline 240 is provided on the mounting seat 200 and is arranged in a vertical direction so as to connect the closed chamber 110 with the outside world. A gravity ball 250 is movably raised and lowered in the gas pipeline 240. The upper end and the lower end of the gas pipeline 240 respectively have an upper constricted portion 241 and a lower constricted portion 242 which can be sealed with the gravity ball 250. A notch portion 243 is provided on the side wall of the gas pipeline 240. When the soft plastic bottle body 100 is placed upright, the gravity ball 250 is in sealing contact with the lower constricted portion 242 so that the notch portion 243 can connect the upper constricted 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 constricted portion 241 so that the notch portion 243 is isolated from the upper constricted portion 241. It is understandable that when the hair dye mixing and discharging device of the present invention is used normally, the soft gel bottle body 100 needs to be inverted, that is, the soft gel 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 gel 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 neck portion 242 due to 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 pipeline 240 and the upper neck portion 241 in sequence, and when the gas enters the gas pipeline 240 from the notch portion 243, it can also exert pressure to keep the gravity ball 250 against the lower neck portion 242.

[0047] See also Fig. 9 and Fig.10In some embodiments of the present invention, the valve body 400 has a horizontally placed cylindrical member 401, the partition 450 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, and at least one end of the sleeve portion 421 of the valve core 420 away from the partition 450 is provided with a pivot portion 422 that penetrates the corresponding sealing end cover 402, a sealing ring 403 is provided between the pivot portion 422 and the sealing end cover 402, and the end of the pivot portion 422 extending out of the sealing end cover 402 is connected to a damping disk 404, 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 keeps rotating for a long time due to inertia, which makes it impossible to stop the fluid discharge in time, thus causing the waste of hair dye. Therefore, by setting the damping adjustment mechanism 800, the waste of hair dye can be greatly reduced, and the force of squeezing the hair dye can 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, the soft gel bottle 100 is easily squeezed uncontrollably during the inversion process, resulting in accidental discharge of the fluid. The brake mechanism 900 can be used to lock the damping disc 404 in advance to prevent the valve core 420 from rotating, which plays a role of multiple insurance. Before squeezing out the hair dye, the valve core 420 needs to be unlocked by the brake mechanism 900.

[0048] Specifically, see Fig.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 disposed on the mounting base 200, the rotating arm 810 has two clamping plates 820 respectively located on both sides of the damping disk 404 and parallel to each other, one of the clamping plates 820 is provided with a plurality of third magnets 830 distributed along the length direction of the rotating arm 810 on the side wall facing the damping disk 404, and the other clamping plate 820 is provided with a plurality of fourth magnets 840 corresponding to the third magnets 830 one by one on the side wall facing the damping disk 404, and 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, and 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 Fig. 9In some embodiments, a magnetic member is provided on the damping disk 404, and a friction pad 910 is provided on the side wall of the damping disk 404. A brake disk 920 that can approach or move away from the friction pad 910 is slidably provided on the mounting seat 200, and the brake disk 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 disk 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 disk 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 power off. The switch is provided on the outer wall of the mounting seat 200 for user convenience.
