DETAILED DESCRIPTION

[0022] In order to facilitate the understanding of those skilled in the art, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figure 1 and Figure 2 As shown, a top-piercing two-component self-spraying paint can includes a can body 1, a partition layer 2 is provided at the bottom of the inner cavity of the can body 1, and the inner cavity of the can body 1 is separated into a main chamber 11 and a sub-chamber 12 by the partition layer 2, which are used to independently store two components of the two-component paint. A through hole 21 connecting the main chamber 11 and the sub-chamber 12 is provided on the partition layer 2, and a sealing sheet 3 is provided on the through hole 21. The sealing sheet 3 is a brittle material, and the sealing sheet 3 seals the through hole 21 to prevent the two components of the two-component paint from mixing. Openings are provided at both ends of the can body 1, and a nozzle 4 connected to the main chamber 11 is provided on the opening at one end, and a top pressure valve 5 extending into the sub-chamber 12 and used to pierce the sealing sheet 3 is provided on the opening at the other end. The openings at both ends of the can body 1 are convenient for pouring the two components of the two-component paint into the main chamber 11 and the sub-chamber 12 respectively. When paint spraying is required, pressure is applied to the top pressure valve 5 so that the top pressure valve 5 punctures the sealing sheet 3. Since the sealing sheet 3 is a brittle material, the sealing sheet 3 is broken over a large area by force, so that the through hole 21 is fully opened, which is convenient for the two components of the two-component paint to be fully mixed. Then the nozzle 4 is pressed to spray the mixed paint, thereby spraying. The sealing sheet 3 is made of glass, ceramic or acrylic material, which is easy to break by force. The nozzle 4 is connected to a liquid supply pipe 41, and the bottom end of the liquid supply pipe 41 extends to the bottom of the main chamber 11, which is convenient for spraying paint.

[0024] like Figure 3 As shown, a step structure 211 is provided on the through hole 21, and a sealing ring 301 is provided at the step structure 211. One side of the edge of the sealing sheet 3 abuts against the sealing ring 301, and the other side is provided with a fixing ring 303. The fixing ring 303 makes the installation and fixation of the sealing sheet 3 reliable, and the sealing ring 301 makes the sealing sheet 3 more effectively seal the through hole 21.

[0025] like Figure 4 , Figure 5 and Figure 6 As shown, the pressure valve 5 includes a sealing cover 51 fixed to the opening, a valve seat 52 is provided on the sealing cover 51, a valve hole 521 is provided in the valve seat 52, a valve core 53 is provided in the valve hole 521 and is movably sealed with the valve hole 521, one end of the valve core 53 is connected to a top thorn 54 with a spike portion 541, the spike portion 541 is arranged just opposite to the sealing sheet 3, and the other end of the valve core 53 penetrates the sealing cover 51 and is exposed on the outer surface of the sealing cover 51. The valve core 53 is pressed, and the valve core 53 slides, thereby driving the top thorn 54 to pierce the sealing sheet 3, and the spike portion 541 presses the sealing sheet 3, so that the sealing sheet 3 is broken.

[0026] A return spring 55 is provided between the valve seat 52 and the valve core 53. The return spring 55 is sleeved on the valve core 53, and the return spring 55 facilitates the reset of the valve core 53. One end of the valve core 53 exposed on the outer surface of the sealing cover is connected with a pressing cover 56. An avoidance groove 511 corresponding to the pressing cover 56 is provided on the sealing cover 51, and the avoidance groove 511 facilitates the travel position when the pressing cover 56 is pressed. A plurality of sharp spines 542 are provided on the puncturing thorn 54, and each sharp spine 542 is distributed on the circumference of the thorn part 541. This structure can effectively increase the breaking area of the sealing sheet 3 and improve the mixing speed of the two-component paint.

[0027] The above embodiments are the preferred implementation manners of the present invention, and are not intended to limit the present invention. Without departing from the inventive concept of the present invention, any obvious replacement is within the protection scope of the present invention.
