Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0055] In the description of this specification, it should be understood that the directional words such as "upper" and "lower" described in the embodiments of the present invention are described at the angles shown in the drawings and should not be understood as limiting the embodiments of the present invention. In addition, in the context, it should also be understood that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0056] like Figure 1 As shown, an embodiment of the present invention provides a color palette, including a power chamber 1, a plurality of pigment chambers 2 and at least one mixing chamber 3;

[0057] The power chamber 1 includes a power piston 4, and the power piston 4 is driven to change the space in the power chamber 1, and the power chamber 1 contains fluid;

[0058] Each of the pigment bins 2 is provided with a metering piston 5, and the metering piston 5 divides the pigment bin 2 into a storage part 201 and a driving part 202, the driving part 202 is connected to the power bin 1 through a driving pipe 6, the storage part 201 is connected to the mixing bin 3 through an output pipe 7, and the mixing bin 3 is connected to a ventilation component;

[0059] The driving pipeline 6 between the power bin 1 and the driving part 202 is provided with a valve 8 to control the communication between the power bin 1 and the driving part 202, and the output pipeline 7 between the material storage part 201 and the mixing bin 3 is provided with a valve 8 to control the communication between the material storage part 201 and the mixing bin 3;

[0060] The mixing chamber 3 is provided with an output unit, through which the pigment is output;

[0061] The pigment bin 2 is used to store pigments and is provided with a scale. By driving the power piston 4 to drive the adjusting piston 5 to move through the fluid, a preset amount of pigment in the pigment bin 2 is pushed into the mixing bin 3 .

[0062] In this embodiment, in order to facilitate accurate blending of pigment colors, pigments of different colors can be placed in different pigment bins 2, and the power bin 1 drives the power piston 4, using the fluid as the pressure carrier to drive the pigment in the pigment bin 2 to be output to the mixing bin 3, and the mixing bin 3 is connected to a breathable component, and the mixing bin 3 achieves air pressure balance through the breathable component, so that the pigment in the pigment bin 2 can smoothly enter the mixing bin 3 under moderate thrust. By controlling the opening and closing of different valves 8, the pigments of different colors can be controlled to enter the mixing bin 3. The pigment bin 2 is provided with a scale, and the amount of the output pigment can be accurately controlled by observing the change of the adjusting piston 5 at different positions of the scale. The mixing bin 3 is provided with an output unit, and the various pigments entering the mixing bin 3 can be output through the output unit.

[0063] In this embodiment, the pigments are stored and mixed in a relatively closed space, which can prevent children or teenagers from spilling the pigments during use, thereby contaminating clothing, the body, and the use environment. At the same time, the new mixing method can increase the fun of the operation.

[0064] In some embodiments of the present invention, a porous plug is provided at one end of the output pipe 7 connected to the mixing chamber 3, and the pigment is sprayed and output in the form of multiple droplets in the mixing chamber 3 through the porous plug, so that pigments of different colors are dispersed in the mixing chamber 3, thereby facilitating uniform mixing.

[0065] In this embodiment, in order to facilitate uniform mixing of pigments of different colors in the mixing chamber 3, a porous plug is used to output the pigment. The pigment can be sprayed out in the form of multiple droplets through the porous plug and distributed more evenly in the mixing chamber 3.

[0066] It is understandable that the valves 8 of the two pigment bins 2 can be opened at the same time, and the power bin 1 can be used to provide power to output two colors of droplets to the mixing bin 3 at the same time, which can further increase the mixing degree and mixing speed of pigments of different colors.

[0067] It should be noted that the top of the pigment bin 2 is made of transparent material, which is convenient for observing the positional relationship between the internal adjusting piston 5 and the scale. The valve 8 can be a rotary valve or a press valve with a simple structure.

[0068] In some embodiments of the present invention, the cross-sectional area of ​​the power piston 4 is not greater than the sum of the cross-sectional areas of any two of the adjusting pistons 5 , the volume of the power chamber 1 is greater than the volume of any one of the pigment chambers 2 , and greater than the volume of the mixing chamber 3 .

[0069] Since the viscosity of the pigment is high and relatively thick, if the pressure provided is insufficient, it is difficult to output fine droplets through the porous plug. Therefore, the cross-sectional area of ​​the power piston 4 is set to be no greater than the sum of the cross-sectional areas of any two of the adjusting pistons 5. In this way, the cross-sectional area of ​​the power piston 4 is multiple times smaller than the cross-sectional area of ​​the adjusting piston. According to the hydraulic principle, when the force output by the power piston 4 is transmitted to the adjusting piston, the output force is also doubled. Although the power piston 4 with a small cross-section can save effort, the displacement of the adjusting piston will be reduced. Therefore, the power bin 1 is set to be long and narrow. In order to ensure that all the pigments in the pigment bin 2 enter the mixing bin 3, the volume of the power bin 1 is set to be larger than the volume of any one of the pigment bins 2, and larger than the volume of the mixing bin 3.

[0070] In some embodiments of the present invention, a feeding door 9 is disposed on the top of the pigment bin 2 , and the feeding door 9 is opened and closed to allow pigment to be added, and one end of the output pipe 7 is disposed at the bottom of the pigment bin 2 .

[0071] In this embodiment, when the pigment bin 2 is filled through the top feeding door 9, if it is filled too full, it is easy to overflow when the feeding door 9 is closed. Therefore, it is preferred to fill it half full. When the pigment bin 2 is half full, it cannot be guaranteed that the volume of the pigment output under the extrusion of the adjusting piston 5 is equal to the volume of the small compression. When the pigment and gas are output together, the effect of accurately adjusting the output pigment through the scale is lost. In order to solve this problem, the output pipe 7 is set at the bottom of the pigment bin 2, so that the end of the output pipe 7 connected to the pigment bin 2 is kept covered with pigment, so that the piston pushes the compression volume equal to the output pigment volume.

[0072] In some embodiments of the present invention, the feeding door 9 is rotatably connected to the top of the pigment bin 2 via a rotating shaft and a hinge.

[0073] In some embodiments of the present invention, the ventilation component includes a ventilation pipe 11 and a ventilation chamber 12 whose maximum volume is not less than the volume of the mixing chamber 3, the mixing chamber 3 is provided with a cleaning piston 14, the space at one end of the cleaning piston 14 is connected to the power chamber 1 through the driving pipe 6, the space at the other end of the cleaning piston 14 is connected to the ventilation chamber 12, the ventilation chamber 12 is provided with an openable and closable communicating hole, the ventilation chamber 12 is provided with a ventilation piston 13, the communicating hole is provided on the wall of the ventilation chamber 12 on the side of the cleaning piston 14 facing the ventilation pipe 11, and the wall of the ventilation chamber 12 on the side of the cleaning piston 14 facing away from the ventilation pipe 11 is provided with an air pressure regulating hole;

[0074] The air-permeable chamber 12 and the air-permeable piston 13 are used to adjust the air pressure. After water is injected through the connecting hole, the mixing chamber 3 can be cleaned through the cooperation of the power piston and the air-permeable piston 13.

[0075] The color palette provided by the present application is a closed type drawing board, and the pigment has a certain viscosity and is easy to adhere to the wall. It is difficult to completely clean it directly after the mixing chamber 3 mixes the pigment. Therefore, the mixing chamber 3 and the air-permeable chamber 12 are used for cleaning. The reciprocating push can not only control the water to enter and exit the mixing chamber 3 for cleaning, but also clean the inner wall of the mixing chamber 3 during the movement of the cleaning piston 14.

[0076] The air pressure regulating hole connects a part of the air-permeable chamber 12 to the atmosphere, so as to facilitate the movement of the air-permeable piston 13.

[0077] In some embodiments of the present invention, a bolt 15 is provided on the top of the power piston, the bolt 15 is rotatably connected to the power piston 4, the power chamber 1 is provided with a thread, and the bolt 15 cooperates with the thread to control the movement of the power piston 4.

[0078] The bolt 15 can precisely control the moving distance of the power piston 4 by rotating it, thereby precisely adjusting the amount of output pigment.

[0079] In some embodiments of the present invention, the output unit is an openable and closable output door 10, and the output door 10 is opened to mix and dip the paint.

[0080] In this embodiment, sealing rings may be provided at the edges of the feeding door 9 and the output door 10 to achieve a sealed connection.

[0081] The embodiment of the present invention further provides a method for cleaning a color palette. Based on the above color palette, the method for cleaning the color palette includes:

[0082] Open the valve 8 between the power chamber 1 and the mixing chamber 3, and close the other valves 8;

[0083] By pushing the power piston 4 to control the pressure of the cleaning piston 14 and the movement of the cleaning piston 14;

[0084] Open the communicating hole to add water into the air-permeable chamber 12, and then close the communicating hole;

[0085] Push and pull the power piston 4 back and forth to allow water to enter and exit the mixing chamber 3 multiple times through the air-permeable pipe 11;

[0086] The communicating hole is opened to discharge the sewage.

[0087] In some embodiments of the present invention, the method for cleaning the pigment bin 2 includes:

[0088] Open the valve 8 between the pigment bin 2 to be cleaned and the power bin 1 and the valve 8 between the pigment bin 2 to be cleaned and the mixing bin 3;

[0089] Open the feeding door 9 and inject water into the pigment bin 2 to be cleaned;

[0090] Push and pull the power piston 4 back and forth to allow water to flow into and out of the paint bin 2 to be cleaned;

[0091] Pushing the power piston 4 to discharge the sewage into the mixing chamber 3;

[0092] Close the valve 8 between the pigment bin 2 to be cleaned and the mixing bin 3, and open the valve 8 between the power bin 1 and the mixing bin 3;

[0093] The power piston 4 is pushed to discharge the sewage into the air-permeable chamber 12 and then discharged through the connecting hole.

[0094] The pigment bin 2 can be filled with one color of pigment for a long time without cleaning. However, if the pigment color needs to be changed or it is not used for a long time and needs to be cleaned, the above method can be used to clean the pigment bin 2.

[0095] It is understandable that a push-pull rod can be installed on the breathable piston 13 to freely adjust the position of the breathable piston 13 when the communicating hole is opened.

[0096] Of course, after cleaning, the sewage can be directly discharged through the feeding door 9. However, in order to prevent stains from remaining on the inner wall of the pigment bin 2, it is preferred to push out the sewage and discharge it through the mixing bin 3 and the ventilation bin 12.

[0097] It should be noted that attention should be paid to the tilt angle when pushing and pulling, so that when the water is pushed to the mixing chamber 3, the water covers the output end of the output pipe 7 under the action of gravity, so that when the power piston 4 is pulled, the water can be sucked into the pigment chamber 2 to be cleaned again.

[0098] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
