Description

Technical Field

[0001] The present invention relates to a water-based pigment preservation device, which relates to a device that can effectively preserve water-based pigments and belongs to the technical field of art supplies. In particular, it relates to a storage structure connected to a sealing structure, in which a moisturizing structure is located above the storage structure in a sealed state. The moisturizing structure replenishes moisture to the pigment in the storage structure, thereby realizing real-time monitoring of the pigment humidity under strong sealing and being able to replenish moisture to maintain the pigment humidity. Background Art

[0002] Water-based paints are widely used due to their rich colors, environmental friendliness and non-toxicity. Currently, water-based paint storage devices usually adopt a simple box structure with several compartments or storage slots inside the box for storing paints. Some water-based paint storage devices have simple sealing covers that are sealed by snaps or threads. Moisturizing usually relies on manual addition of water or simply relies on sealing to reduce water evaporation. Existing water-based paint storage devices mainly have the following problems: in terms of device sealing, the sealing structure of traditional devices is relatively simple, which can easily lead to pigment contamination; in terms of preservation function, existing water-based paint preservation devices mainly use highly sealed boxes or boxes with wet sponges to prevent the paint from drying out, but relying solely on sealing cannot achieve accurate monitoring and adjustment of humidity. Changes in humidity are a key factor affecting the preservation effect of water-based paints. The method of moisturizing with a wet sponge not only requires regular replacement of the sponge, but is also prone to breeding bacteria or mold, leading to pigment contamination, and it is difficult to maintain a good use condition for a long time.

[0003] Announcement No. CN110667300A discloses a paint preservation box, including a main box body, a sealing cover and a cleaning assembly. The interior of the main box body is provided with a plurality of containing shells separated by trays. The interior of the containing shell is provided with a replenishing box and a gear shaft. The upper end of the interior of the replenishing box is threadedly connected to a useful box. The gear shaft can be rotated by the connecting rod of the cleaning assembly, which can maintain the humidity of the paint for a long time and prevent the paint from drying out due to long exposure time. However, the above-mentioned device only relies on the sealing of the device to reduce the evaporation of moisture. In terms of moisturizing, it is impossible to accurately monitor the humidity of the paint in real time. The humidity of the paint can only be judged based on experience, and it can only rely on manual addition of moisture, which makes it difficult to ensure the quality of the paint.

The nozzle placement grooves (10) are equipped with spray nozzles (12). The spray nozzles (12) are connected to the transmission pipe (17). The transmission pipes (17) in the sealed chamber separated by the group sealing strip (14) inside the same sealing cover (8) are all connected to the same The water pipe (16) is connected, a water pipe placement groove (15) is provided in the sealing cover (8) at a position corresponding to the water pipe (16), the water pipe (16) is placed in the water pipe placement groove (15), and the sealing cover (8) is separated by the storage strip (4) into each sealed compartment, and a humidity sensor (13) is provided in each sealed compartment; the signal converter is placed on the sealing cover (8) and is connected to the humidity sensor (13) through a data transmission line, the data processor is placed on the sealing cover (8) and is connected to the signal converter through a data transmission line, the controller is placed on the sealing cover (8) and is connected to the data processor through a data transmission line, and the spray nozzle (12) is connected to the controller through a data transmission line; The signal converter is capable of receiving a humidity signal from a humidity sensor (13) and performing signal conversion; The data processor and the signal converter exchange information.

[0012] The difference between this embodiment and embodiment 1 is that a plurality of anti-adsorption particles (19) are evenly arranged at the bottom of the storage box (1). When taking out the paint, part of the paint may fall on the bottom of the storage box (1). The anti-adsorption particles (19) form a certain gap between the paint and the bottom of the storage box, reducing the contact area between the paint and the bottom of the box and reducing the possibility of the paint sticking to the bottom of the box. When cleaning the storage box, the residual paint is easier to clean, avoiding the breeding of bacteria due to the long-term residual paint, which affects the subsequent use and preservation of the paint. Example 3

[0013] The difference between this embodiment and embodiment 1 is that an auxiliary sealing groove (20) is provided on the contact surface between the group sealing strip (14) and the pigment receiving groove (4), and the size of the auxiliary sealing groove (20) is consistent with the edge size of the pigment receiving groove (4). The auxiliary sealing groove (20) and the edge size of the pigment receiving groove (4) are consistent and can fit accurately. When the sealing cover (8) is closed, an additional sealing barrier is formed. When the edge sealing strip (9) and the auxiliary sealing groove (3) cooperate to achieve overall sealing, the auxiliary sealing groove (20) further fills the small gap that may exist between the group sealing strip (14) and the pigment receiving groove (4), further improving the sealing effect, and at the same time preventing the pigment volatiles from diffusing between the storage bins, thereby avoiding the color bleeding phenomenon. The height of the partition plate (5) is slightly lower than the edge height of the pigment storage tank (4), which can prevent the pigment from flowing over the partition plate (5) into the adjacent storage bin due to excessive addition, and confine the pigment to a single storage bin, ensuring that pigments of different types and colors will not mix and contaminate each other, and maintain the purity and independence of the pigments; The partition plate (5) and the pigment storage tank (4) are designed to be detachably sealed and connected, and the partition plate (5) can be rearranged as needed to freely adjust the number, size and layout of the storage bins. The detachable design facilitates cleaning and maintenance, avoiding cleaning dead corners. The design of coating the surface of the storage box (1) and the pigment storage slot (4) with an antibacterial coating can effectively inhibit the growth and reproduction of bacteria, and prevent bacteria from decomposing the pigment components during the long-term storage of the pigment, causing the pigment to change color and deteriorate, thereby maintaining the color brightness and chemical stability of the pigment; The arc slope (18) is generally concave in shape with a concave middle and convex sides. The surface of the arc slope (18) is coated with a hydrophobic coating. The concave arc design can make the pigment automatically converge to the middle, concentrate the pigment position, and facilitate the scraping tool to scrape more pigment at one time. At the same time, the concave arc structure is easy to clean, can avoid cleaning dead corners, and with the hydrophobic coating, effectively reduces the difficulty of cleaning and facilitates daily maintenance; The auxiliary sealing groove (3) is made of a thermoplastic elastomer material and is added with an antibacterial agent and an anti-aging agent. The thermoplastic elastomer material has good elasticity and flexibility, can fit closely to the edge sealing strip (9), adapt to different degrees of extrusion deformation, and ensure the sealing effect; the addition of the antibacterial agent can inhibit the growth of bacteria in the sealing groove, avoiding the influence of the bacterial growth on the pigment quality; the anti-aging agent can extend the service life of the sealing groove and ensure long-term stable sealing performance; The material of the opening edge of the sealing cover (8) is a metal material with good magnetic conductivity, and a plurality of micro permanent magnets are embedded in the inner side of the auxiliary fixing strip (7). When the auxiliary fixing strip (7) contacts the sealing cover (8), the magnetic force makes the two fit tightly together, and the magnetic connection can provide a stable force in all directions, ensuring that the sealing cover (8) and the storage box (1) always maintain a good connection state, creating a stable storage space for the pigment; The purpose of replenishing moisture to the pigment in the storage structure through the moisturizing structure is achieved, and the humidity of the pigment is monitored in real time under strong sealing and the moisture can be replenished to maintain the humidity of the pigment.
