Description

Technical Field

[0001] This utility model relates to the field of spray paint can technology, specifically a new type of environmentally friendly self-spraying paint can. Background Technology

[0002] Spray paint is a portable paint packaging product consisting of an aerosol can, an aerosol valve, the contents (paint), and a hardener. It is widely used in home DIY, car repair, artistic creation, and industrial coating.

[0003] Existing spray paint cans are used by first mixing the hardener with the contents to turn the contents into easily sprayable mist particles. Then, the nozzle is pressed, and the paint is drawn into the nozzle position through the liquid inlet tube. Finally, the mist paint is sprayed out through the aerosol valve at the nozzle position, thus achieving the spraying of the item.

[0004] However, in most spray paint cans, the inlet tube is typically located inside the can, with its end usually at the bottom of the can's interior to draw up paint for spraying. Even when the inlet tube is in direct contact with the bottom wall of the can's interior, some paint may still fail to enter the inlet tube when the can is nearly empty. This can lead users to mistakenly believe the paint is used up and discard the can, resulting in paint waste. To address this, we propose a new type of environmentally friendly spray paint can to effectively solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a new type of environmentally friendly self-spraying paint can to solve the problems mentioned in the background art.

[0010] Optionally, the moving component includes a slide bar that vertically penetrates the bottom wall of the curing agent storage chamber, and a piston is fixedly provided at the top of the slide bar, which is slidably disposed at the discharge port.

[0011] Optionally, a push plate is fixedly provided at the bottom end of the slide bar, and push rods are fixedly provided at the bottom of both the left and right ends of the push plate. Both push rods are arranged vertically, and the bottom ends of the two push rods extend to the bottom of the tank. The bottom ends of the two push rods are connected to a pressing plate.

[0012] Optionally, a spring is fitted on the outer side of a section of the slide rod extending to the bottom of the curing agent storage chamber, with the upper and lower ends of the spring abutting against the bottom of the curing agent storage chamber and the top of the push plate, respectively; in its natural state, the spring is in a compressed state.

[0013] Compared with the prior art, this utility model provides a new type of environmentally friendly spray paint can, which has the following characteristics:

[0014] Beneficial effects:

[0015] This invention incorporates a funnel-shaped storage tank within the main body of the container, creating a connection gap between the storage tank and the main body. This allows the liquid inlet pipe to be moved from inside the storage tank into the connection gap, enabling the pipe to connect to the bottom of the storage tank from the outside.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 - Figure 3 A novel environmentally friendly self-spraying paint can includes a can body 1, with a pressing nozzle 101 at the top. The interior of the can body 1 is hollow, and a storage tank 2 is fixedly installed inside the cavity of the can body 1. The bottom of the storage tank 2 is funnel-shaped, and a discharge pipe 201 is fixedly installed at the bottom of the storage tank 2. This allows the contents to be stored in the storage tank 2 and then discharged from the discharge pipe 201 at the bottom of the storage tank 2, ensuring better drainage of the contents and preventing waste caused by excessive residue that cannot be absorbed. Furthermore, the double-layer structure provides protection for the storage tank 2 from the can body 1, allowing the device to continue functioning even if the can body 1 is damaged.

[0023] It is worth mentioning that the inner wall of the storage tank 2 is coated with a nano-Teflon anti-stick coating, which gives the inner wall of the storage tank 2 excellent anti-stick performance. The nano-Teflon coating has a smooth surface and extremely low adhesion, which can prevent various substances from easily adhering to its surface. This makes it difficult for the paint in the storage tank 2 to adhere to the inner wall, thereby allowing the paint to be sprayed out and used to a great extent, improving the utilization rate of the paint and making the device more environmentally friendly.

[0024] A connection gap 3 exists between the tank body 1 and the storage tank 2. A connector 301 is fixedly installed within the connection gap 3. The tank body 1 and the storage tank 2 are fixedly connected by the connector 301, so that the storage tank 2 can be fixed inside the tank body 1, avoiding direct contact between the tank body 1 and the storage tank 2, thus improving the protective effect of the tank body 1 on the storage tank 2. The pressing nozzle 101 and the discharge pipe 201 are connected by a liquid inlet pipe 4. The liquid inlet pipe 4 is located within the connection gap 3, so that the liquid inlet pipe 4 is not directly placed inside the storage tank 2 to draw in the contents, but rather cooperates with the funnel-shaped bottom of the storage tank 2 and the discharge pipe 201 to draw in the contents from the outside of the storage tank 2. The method of drawing in the contents from the outside of the discharge pipe 201, relative to the liquid inlet pipe 4 being located inside the storage tank 2, reduces the final residual contents in the storage tank 2, thereby improving the utilization rate of the paint. After use, the disposal of the paint can also reduce the environmental harm caused by the contents, making it more environmentally friendly.

[0025] Furthermore, the storage tank 2 is hollow inside, and a curing agent storage chamber 5 is fixedly installed inside the storage tank 2. The storage tank 2 and the curing agent storage chamber 5 are fixedly connected by a support member 202. The curing agent storage chamber 5 is also hollow inside, and a discharge port 501 is opened at the top of the curing agent storage chamber 5 so that there is a gap between the storage tank 2 and the curing agent storage chamber 5, so that the contents inside the storage tank 2 can mix with the curing agent in the curing agent storage chamber 5, thereby turning the contents into a mist of particles, which is convenient for spraying.

[0026] In order to control when the curing agent in the curing agent storage chamber 5 mixes with the contents, this application has a moving component 6 slidably connected vertically to the curing agent storage chamber 5. The moving component 6 is used to control the opening and closing state of the discharge port 501. The moving component 6 is described in detail below:

[0027] The moving component 6 includes a slide bar 601, which vertically penetrates the bottom wall of the curing agent storage chamber 5. A piston 602 is fixedly provided at the top of the slide bar 601. The piston 602 is vertically slidably disposed at the discharge port 501, so that when the slide bar 601 moves up and down on the curing agent storage chamber 5, it can drive the piston 602 to move up and down at the discharge port 501, thereby realizing the closing and opening of the discharge port 501.

[0028] Furthermore, a push plate 603 is fixedly provided at the bottom end of the slide rod 601, and push rods 604 are fixedly provided at the bottom of both the left and right ends of the push plate 603. Both push rods 604 are arranged vertically, and the bottom ends of the two push rods 604 extend to the bottom of the tank body 1. The bottom ends of the two push rods 604 are connected to a pressing plate 605, so that the user can press the pressing plate 605 on the outside of the bottom of the tank body 1, thereby enabling the push rods 604 to push the push plate 603 to move, which in turn causes the slide rod 601 to move, and finally drives the piston 602 to move at the discharge port 501, making it easier to control the discharge of the curing agent.

[0029] It should be noted that sealing elements are provided between the slide rod 601 and the bottom wall of the curing agent storage chamber 5, between the push rod 604 and the bottom wall of the storage tank 2, and between the push rod 604 and the bottom wall of the tank body 1. The sealing elements are slidably connected to the slide rod 601 and the push rod 604 so that the contents of the storage tank 2 and the curing agent storage chamber 5 will not leak, and at the same time, the vertical sliding process of the slide rod 601 and the push rod 604 will not be affected.

[0030] Furthermore, a spring 606 is fitted on the outer side of the section of the slide rod 601 extending to the bottom of the curing agent storage chamber 5. The upper and lower ends of the spring 606 abut against the bottom of the curing agent storage chamber 5 and the top of the push plate 603, respectively. In its natural state, the spring 606 is in a compressed state, so that when the user releases the pressing plate 605, the spring 606 will push the push plate 603 towards the bottom of the tank 1, thereby causing the slide rod 601 and the piston 602 to move downward, and then causing the piston 602 to be embedded in the leakage port 501, thereby sealing the leakage port 501.

[0031] The working principle and usage process of this utility model are as follows: First, in use, invert the can 1 and press the bottom pressing plate 605. The pressing plate 605 will drive the push rod 604 to move into the storage tank 2. The push rod 604 pushes the push plate 603 to move into the curing agent storage chamber 5. The push plate 603 will then push the slide rod 601 to move into the discharge port 501. The slide rod 601 will eventually push the piston 602 out of the discharge port 501. At this time, the curing agent in the curing agent storage chamber 5 will leak out. At this time, the contents of the storage tank 2 are located at the end near the pressing nozzle 101, thus preventing them from entering the curing agent storage chamber 5. Subsequently, after the curing agent leaks out and mixes with the contents, release the pressing plate 605. The spring 606 will cause the pressing plate 605 to return to its original position, causing the slide rod 601 to drive the piston 602 to move back into the discharge port 501, thereby sealing the discharge port 501 and preventing the curing agent from leaking out further. Finally, return the can 1 to its upright position, shake the can 1 to fully mix the contents and hardener, and atomize the contents into mist-like particles. Then press the press nozzle 101 to draw the contents of the storage tank 2 into the press nozzle 101 through the liquid inlet pipe 4 and the discharge pipe 201, thus completing the spraying of the item.
