The top of the sprayer body is provided with a guide groove into which the sliding member can be inserted and slidably connected. The guide groove is inclinedly disposed on the top of the sprayer body.

[0005] When the pressure ring drives the telescopic pressure ring to rotate in the first direction, the sliding member slides along the guide groove and drives the telescopic pressure block to move towards the center of the bottle body, and presses the inner liner and / or lid of the paint bottle through the telescopic pressure block; when the pressure ring drives the telescopic pressure ring to rotate in the second direction, the sliding member slides along the guide groove and drives the telescopic pressure block to move away from the center of the bottle body to loosen the inner liner and / or lid of the paint bottle.

[0006] Optionally, the top of the pot body is fixedly provided with an annular flange extending outward from the pot body, and the top of the pot body is provided with an annular platform inside the annular flange, the top surface of the annular platform being lower than the top surface of the annular flange.

[0007] Optionally, the pressure ring includes an annular body, a first sidewall extending downward from the inner side of the annular platform, and a second sidewall extending downward from the outer side of the annular platform. When the pressure ring is placed on the top of the annular body, the first sidewall and the second sidewall are respectively sandwiched between the inner and outer sides of the annular flange.

[0008] The first sidewall is provided with a first barb, the second sidewall is provided with a second barb, and the annular flange is provided with a strip groove through which the first barb can pass and hook onto the bottom wall of the annular flange. The second barb hooks onto the bottom wall of the annular flange from the outside of the annular flange.

[0011] Optionally, the outer side wall of the first barb is provided with a protruding buckle, and the side wall of the strip groove is provided with a first positioning groove and a second positioning groove at a position corresponding to the protruding buckle, so that the protruding buckle can be engaged and connected.

[0012] When the pressure ring drives the telescopic pressure block to extend from the first and second extension openings, the protruding buckle is engaged in the second positioning groove for positioning. When the pressure ring drives the telescopic pressure block to retract to the first and second extension openings, the protruding buckle is engaged in the first positioning groove for positioning.

[0013] Optionally, the guide groove is disposed on the annular flange, and the guide groove extends from the outer side of the annular flange to the inner side of the annular flange.

[0014] As described above, the paint sprayer with a detachable and replaceable inner liner of this utility model has the following beneficial effects: When using the paint sprayer with a detachable and replaceable inner liner of this utility model, when it is necessary to replace the inner liner, the pressure ring can be rotated. The pressure ring drives the telescopic pressure ring to rotate together with the pressure ring. At the same time, the sliding block located on the telescopic pressure ring rotates, and the sliding member rotates along the guide groove in the guide groove. Since the guide groove is inclinedly set at the top of the sprayer body, during the rotation of the telescopic pressure block in the first direction, the sliding member slides along the guide groove and drives the telescopic pressure block to move towards the center of the sprayer body. The telescopic pressure block presses the top edge of the inner liner and / or the edge of the sprayer lid, thereby fixing the inner liner and / or the lid. When it is necessary to loosen the inner liner and / or the lid, rotate the pressure ring in the opposite direction. The pressure ring drives the telescopic pressure ring to rotate in the second direction. The sliding member slides in the opposite direction along the guide groove and drives the telescopic pressure block to move away from the center of the sprayer body, thereby loosening the top edge of the inner liner and / or the edge of the lid, so that the inner liner can be quickly removed and replaced.
