DETAILED DESCRIPTION

[0023] 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.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a pull-out two-component spray can includes a tank body 1, and a nozzle 2 is provided on the top of the tank body 1, and the nozzle 2 is used to spray the liquid in the tank body 1. The nozzle 2 is connected to a liquid supply pipe 21, and the bottom end of the liquid supply pipe 21 extends to the bottom of the inner cavity of the tank body 1. The nozzle 21 can basically spray out all the liquid in the tank body 1, avoiding excessive liquid from remaining in the tank body 1 and excessive waste.

[0025] The bottom end of the tank body 1 is provided with a through hole 11, and a cylindrical tank 3 extending into the inner cavity of the tank body 1 is fixed in the through hole 11. During production and assembly, it is only necessary to insert the cylindrical tank 3 into the through hole 11 and then fix it. The production process is simple and the cost is low. The two-component agent is stored in the inner cavity of the tank body 1 and the inner cavity of the cylindrical tank 3 respectively, and is separated by the wall of the cylindrical tank 3. The cylindrical tank 3 is of a regular shape. When different volumes are required in the cylindrical tank 3, cylindrical tanks 3 of different specifications and lengths can be used, and the control is accurate and convenient.

[0026] The lower part of the side wall of the cylindrical tank 3 is provided with a connecting hole 31 for connecting the inner cavity of the cylindrical tank 3 and the inner cavity of the tank body 1. The liquid in the inner cavity of the cylindrical tank 3 and the inner cavity of the tank body 1 can be mixed through the connecting hole 31. Since the connecting hole 31 is located at the lower part of the side wall of the cylindrical tank 3, when in use, the liquid in the cylindrical tank 3 can basically flow into the inner cavity of the tank body 1 through the connecting hole 31, and then be sprayed out for use, with less residual liquid accumulation, avoiding excessive waste. There are multiple connecting holes 31, which are arranged in a circle on the side wall of the cylindrical tank 3. This structure can increase the flow area between the inner cavity of the cylindrical tank 3 and the inner cavity of the tank body 1, and increase the uniformity of liquid mixing between the two inner cavities.

[0027] The lower end of the cylindrical tank 3 is provided with an opening 32, and the opening 32 is exposed outside the tank body 1. Liquid can be directly poured into the cylindrical tank 3 through the opening 32, which is convenient for filling and improves production efficiency. A pull-out valve 4 is provided at the opening 32, and a sealing plug 5 that is movably sealed with the inner wall of the cylindrical tank 3 is provided in the cylindrical tank 3. The pull-out valve 4 is connected to the sealing plug 5. When the sealing plug 5 is located above the connecting hole 31, the liquid in the inner cavity of the cylindrical tank 3 can be sealed without contacting the liquid in the tank body 1. When the pull-out valve 4 is operated to pull the sealing plug 5 to slide below the connecting hole 31, the liquid in the inner cavity of the tank body 1 and the inner cavity of the cylindrical tank 3 are contacted and mixed through the connecting hole 31. A sealing ring 51 is sleeved on the sealing plug 5 to increase the sealing effect. There are two sealing rings 51, which are distributed at the upper and lower parts of the sealing plug 5, which further improve the sealing effect and make the sliding of the sealing plug 5 more stable.

[0028] The pull-out valve 4 includes a sealing cover 41 that seals the opening 32. The sealing cover 41 is provided with a sliding hole 42. A pull rod 43 that is movably sealed with the sliding hole 42 is provided in the sliding hole 42. The upper end of the pull rod 43 is connected to the sealing plug 5, and the lower end is exposed outside the sealing cover 41. The sealing plug 5 can be pulled to slide in the cylindrical tank 3 by pulling the pull rod 43. A transverse hole 431 is provided at the lower end of the pull rod 43. A pull ring 47 is installed on the transverse hole 431, and the pull rod 43 can be easily pulled through the pull ring 47.

[0029] A groove 44 is provided at the edge of the sliding hole 42 on the sealing cover 41, and a sealing ring 45 is provided in the groove 44 and is sleeved on the pull rod 43. A fixed pressure block 46 is provided in the groove 44 to press and fix the sealing ring 45. The setting of the sealing ring 45 facilitates sealing the gap between the pull rod 43 and the sealing cover 41 to avoid liquid leakage between the pull rod 43 and the sealing cover 41.

[0030] The working process of this embodiment is as follows: during filling, firstly, the first component is poured into the cylindrical tank 3 through the opening 32, and then the sealing plug 5 and the pull-out valve 4 are assembled. At this time, the sealing plug 5 seals the first component in the cylindrical tank 3, and then the second component is poured into the tank body 1, and then the nozzle 2 is installed, thereby completing the filling of the two-component agent. During use, the sealing plug 5 is pulled to slide through the pull-out valve 4, so that the connecting hole 31 connects the inner cavity of the cylindrical tank 3 with the inner cavity of the tank body 1, and the two-component agent is mixed and sprayed through the nozzle 2.

[0031] The above embodiments are preferred implementations 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 replacements are within the protection scope of the present invention.
