Description

Technical Field

[0001] This application relates to the field of spray guns, and in particular to a real stone paint spray gun with adjustable atomization. Background Technology

[0002] A stone paint spray gun is an essential tool for transforming stone paint coatings into wall finishes. It uses compressed air to atomize and spray the coating. Existing stone paint spray guns require changing nozzles of different diameters depending on the sand pattern, a cumbersome process that is prone to loss. CN217615369U discloses an integrated adjustable nozzle diameter stone paint spray gun. By rotating a nozzle switching device, the desired diameter outlet is aligned with the nozzle outlet, allowing for easy switching between different nozzle diameters. This provides a variety of nozzle diameters to meet the needs of different sand patterns and spraying effects. CN207042703U discloses a stone paint spray gun with an optimized overall structure. Threaded connections between mechanisms allow for direct disassembly and cleaning in case of blockage or after use. A distributor pipe further enhances the mixing of high-pressure air and stone paint raw materials, improving spraying quality.

[0003] The aforementioned stone paint spray guns also have the following problems: all of the aforementioned stone paint spray guns use a direct triggering device to spray stone paint, but none of them are equipped with components for adjusting the atomization level. This makes it difficult to adjust the spray atomization of the spray gun, and thus makes it difficult for the spray gun to adapt to different decorative needs with different atomization requirements. Summary of the Invention

[0004] In view of this, this application provides a real stone paint spray gun with adjustable atomization, which can adjust the atomization.

[0005] To achieve the above objectives, this application employs the following technical solution:

[0006] A real stone paint spray gun with adjustable atomization, characterized in that it includes a spray gun body, an adjustment mechanism, and a nozzle; the spray gun body is provided with a handle and a feed inlet; the adjustment mechanism includes a mechanism tube fixedly installed on the spray gun body, a valve seat fixedly installed inside the mechanism tube, an adjustment sleeve movably sleeved outside the mechanism tube and capable of telescopic movement, a valve core fixedly installed inside the adjustment sleeve, and a telescopic adjustment structure for driving the adjustment sleeve to telescopically move; the spray gun body has a channel connecting the feed inlet and the mechanism tube; the valve seat has a frustum-shaped groove with a smaller diameter at one end near the spray gun body, the groove is coaxially arranged with the mechanism tube and both ends of the groove are respectively connected to the mechanism tube; the valve core is frustum-shaped and movably installed in the groove; the nozzle is fixedly installed at the end of the adjustment sleeve; when the adjustment sleeve moves axially towards the mechanism tube with the valve core, the gap between the valve core and the groove decreases; when the adjustment sleeve moves away from the mechanism tube with the valve core, the gap between the valve core and the groove increases, thereby adjusting the atomization.

[0007] The above-mentioned atomization controllable stone paint spray gun of this application can adjust the gap between the valve core and the valve seat by adjusting the movement position of the valve core in the tank. Since the material passes through different gaps, the atomization effect of the spray nozzle is different, thus achieving the purpose of adjusting the atomization effect.

[0008] In some embodiments, an installation sleeve is also fixedly provided on the mechanism tube. The installation sleeve is placed outside the mechanism tube, and the adjusting sleeve moves telescopically within the gap between the installation sleeve and the mechanism tube. The telescopic adjustment structure includes a worm gear rotatably connected inside the installation sleeve and a rack fixedly provided on the outer wall of the adjusting sleeve. The worm gear and the rack cooperate to drive the transmission. When the worm gear rotates, it can drive the rack and the adjusting sleeve to move telescopically together.

[0009] In some embodiments, the number of worm gears is multiple and circumferentially spaced, and the number of racks is also multiple and circumferentially spaced. A gear is fixedly mounted on one end of each worm gear near the adjusting sleeve. A gear ring is coaxially rotatably connected to the mounting sleeve. The gear ring engages with each gear for transmission, so that the gear ring can drive each gear and the worm gear to rotate together during rotation. Rotating the gear ring can drive all the gears to rotate synchronously, which in turn drives the worm gears to rotate, resulting in synchronous rotation of all the worm gears. This causes the forces on all parts of the adjusting sleeve to be balanced, making the movement of the adjusting sleeve more stable.

[0010] In some embodiments, a quick-release assembly is fixedly provided at the end of the mechanism tube. The quick-release assembly includes a retaining ring fixedly connected to the mechanism tube and the mounting sleeve. The inner wall of the retaining ring is used to fit onto the corresponding connector of the spray gun body. The retaining ring has multiple circumferentially spaced clearance grooves, which are radially connected at both ends. A ball is installed in the clearance groove. A limit ring is rotatably provided on the outer wall of the retaining ring. The inner wall of the limit ring has multiple circumferentially spaced ball grooves. When the limit ring rotates and separates the ball grooves from the clearance grooves, the inner wall of the limit ring presses down on the ball, causing the ball to move radially toward the axis of the retaining ring so that the ball can enter the retaining groove on the connector, allowing the retaining ring to lock the connector on the spray gun body. When the ball grooves align with the clearance grooves, the ball can partially enter the ball grooves, thereby releasing the locking state of the connector. The limit ring is also provided with a locking structure for fixing the limit ring in the state where the ball grooves and clearance grooves are separated.

[0011] When the ball groove and the ball are misaligned, the ball clamps the connector on the spray gun body. Rotating the limit ring aligns the ball groove with the ball, allowing the ball to move and the retaining ring to be removed from the spray gun body 1, thus achieving quick disassembly and assembly.

[0012] In some embodiments, the spray gun body is provided with two circumferentially spaced insertion holes. The locking structure includes a push block slidably connected to the limiting ring along the axial direction of the limiting ring and a spring connected between the push block and the limiting ring to provide an elastic restoring force for movement toward the insertion hole. When the push block is inserted into the first insertion hole, the ball groove of the limiting ring and the clearance groove of the retaining ring are in a separated state. When the push block is inserted into the second insertion hole, the ball groove of the limiting ring and the clearance groove of the retaining ring are in contact.

[0013] When the push block is inserted into the first socket, there is no relative rotation between the limit ring and the retaining ring. Pushing the push block to the right allows it to disengage from the first socket, which in turn allows the limit ring to rotate. When the cam shaft switches positions between two adjacent sockets, the positions of the ball groove and the ball are switched between aligned and staggered states, which facilitates disassembly and adjustment of the mechanism and cleaning.

[0014] In some embodiments, the inner wall of the retaining ring is provided with a limiting groove, and the connector of the spray gun body is provided with a limiting protrusion that mates with the limiting groove. The limiting groove and the limiting protrusion engage, allowing the ball bearings to directly align with the retaining groove on the spray gun body, preventing misalignment. This limiting groove also allows for the calibration of the retaining ring's position.

[0015] In some embodiments, the adjusting sleeve is further provided with scale lines. The scale lines are used to indicate the amount of movement of the valve core, and thus correspond to the degree of atomization.

[0016] As can be seen from the above technical solution, this application has at least the following advantages and positive effects:

[0017] This application discloses a real stone paint spray gun with adjustable atomization. By adjusting the movement position of the valve core in the tank, the gap between the valve core and the valve seat can be adjusted. Since the material passes through different gaps, the atomization effect of the spray nozzle is different, thus achieving the purpose of adjusting the atomization effect. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the application will be described in further detail below with reference to the accompanying drawings. The terminology used in the embodiments section of this application is only for explaining specific embodiments and is not intended to limit the application.

[0025] See Figures 1 to 5This application provides a real stone paint spray gun with adjustable atomization, including a spray gun body 1, an adjustment mechanism 4, and a nozzle 5. The spray gun body 1 is provided with a handle 2 and a feed inlet 3. The adjustment mechanism 4 includes a mechanism tube 41 fixedly installed on the spray gun body 1, a valve seat 42 fixedly installed inside the mechanism tube 41, an adjustment sleeve 43 movably sleeved outside the mechanism tube 41 and capable of telescopic movement, a valve core 44 fixedly installed inside the adjustment sleeve 43, and a telescopic adjustment structure for driving the adjustment sleeve 43 to telescopically move. A channel connecting the feed inlet 3 and the mechanism tube 41 is provided inside the spray gun body 1; the valve seat 42... A frustum-shaped groove 421 with a smaller diameter at one end near the spray gun body 1 is provided in the middle. The groove 421 is coaxially arranged with the mechanism tube 41 and both ends of the groove 421 are connected to the mechanism tube 41. The valve core 44 is frustum-shaped and is movably installed in the groove 421. The nozzle 5 is fixedly installed at the end of the adjusting sleeve 43. When the adjusting sleeve 43 moves axially toward the mechanism tube 41 with the valve core 44, the gap between the valve core 44 and the groove 421 decreases. When the adjusting sleeve 43 moves away from the mechanism tube 41 with the valve core 44, the gap between the valve core 44 and the groove 421 increases, thereby adjusting the atomization.

[0026] This adjustable atomization stone paint spray gun can adjust the gap between the valve core 44 and the valve seat 42 by adjusting the movement position of the valve core 44 in the tank 421. As the material passes through different gaps, the atomization effect of the spray nozzle 5 is different, thus achieving the purpose of adjusting the atomization effect.

[0027] An installation sleeve 410 is also fixedly installed on the mechanism tube 41. The installation sleeve 410 is sleeved on the outside of the mechanism tube 41. The adjusting sleeve 43 moves in and out within the gap between the installation sleeve 410 and the mechanism tube 41. The telescopic adjustment structure includes a worm gear 45 rotatably connected in the installation sleeve 410 and a rack 46 fixedly installed on the outer wall of the adjusting sleeve 43. The worm gear 45 and the rack 46 cooperate to drive the transmission. When the worm gear 45 rotates, it can drive the rack 46 and the adjusting sleeve 43 to move in and out together.

[0028] Multiple worm gears 45 are arranged circumferentially at intervals, as are multiple racks 46, also arranged circumferentially at intervals. A gear 48 is fixedly mounted on one end of each worm gear 45 near the adjusting sleeve 43. A gear ring 49 is coaxially rotatably connected to the mounting sleeve 410. The gear ring 49 engages with each gear 48 for transmission, enabling the gear ring 49 to drive each gear 48 and the worm gear 45 to rotate together during rotation. Rotating the gear ring 49 drives all the gears 48 to rotate synchronously, which in turn drives the worm gears 45 to rotate, resulting in synchronized rotation of all worm gears 45. This ensures that the forces on all parts of the adjusting sleeve 43 are balanced, making the movement of the adjusting sleeve 43 more stable.

[0029] A quick-release assembly 47 is fixedly provided at the end of the mechanism tube 41. The quick-release assembly 47 includes a retaining ring 471 fixedly connected to the mechanism tube 41 and the mounting sleeve 410. The inner wall of the retaining ring 471 is used to fit onto the corresponding connecting head of the spray gun body 1. The retaining ring 471 has a plurality of circumferentially spaced clearance grooves, the two ends of which are connected radially. Ball bearings 472 are installed in the clearance grooves. A limit ring 473 is rotatably provided on the outer wall of the retaining ring 471. The inner wall of the limit ring 473 has a plurality of circumferentially spaced ball grooves 474. 3. When the ball groove 474 is rotated to separate from the clearance groove, the inner wall of the limiting ring 473 presses against the ball 472, so that the ball 472 moves radially towards the axis of the retaining ring 471, so that the ball 472 can enter the retaining groove 11 on the connector head, allowing the retaining ring 471 to lock the connector on the spray gun body 1; when the ball groove 474 is docked with the clearance groove, the ball 472 can partially enter the ball groove 474, thereby releasing the locking state of the connector head; the limiting ring 473 is also provided with a locking structure for fixing the limiting ring 473 in the state where the ball groove 474 and the clearance groove are separated.

[0030] When the ball groove 474 and the ball 472 are misaligned, the ball 472 clamps the connector on the spray gun body 1. Rotating the limit ring 473 makes the ball groove 474 aligned with the ball 472, allowing the ball 472 to move. This allows the retaining ring 471 to be removed from the spray gun body 11, thus achieving a quick disassembly and assembly effect.

[0031] The spray gun body 1 is provided with two circumferentially spaced insertion holes 477. The locking structure includes a push block 475 that is slidably connected to the limiting ring 473 along the axial direction of the limiting ring 473, and a spring 476 connected between the push block 475 and the limiting ring 473 to provide an elastic restoring force for moving towards the insertion hole 477. When the push block 475 is inserted into the first insertion hole 477, the ball groove 474 of the limiting ring 473 is separated from the clearance groove of the retaining ring 471. When the push block 475 is inserted into the second insertion hole 477, the ball groove 474 of the limiting ring 473 is engaged with the clearance groove of the retaining ring 471.

[0032] When the push block 475 is inserted into the first socket 477, there will be no relative rotation between the limiting ring 473 and the retaining ring 471. Pushing the push block 475 to the right allows it to disengage from the first socket 477, thereby allowing the limiting ring 473 to rotate. When the cam shaft switches positions between two adjacent sockets 477, the positions of the ball groove 474 and the ball 472 switch between aligned and staggered states, facilitating the disassembly and adjustment of the mechanism 4 for cleaning.

[0033] The inner wall of the retaining ring 471 is provided with a limiting groove 478, and the connector of the spray gun body 1 is provided with a limiting protrusion that cooperates with the limiting groove 478. The limiting groove 478 and the limiting protrusion engage, so that the ball bearing 472 can be directly aligned with the retaining groove 11 on the spray gun body 1, preventing them from misaligning. In this way, the limiting groove 478 can calibrate the position of the retaining ring 471.

[0034] The adjusting sleeve 43 is also provided with a scale line 411. The scale line 411 is used to indicate the amount of movement of the valve core 44, and thus corresponds to the degree of atomization.

[0035] The following is a brief description of the working process and usage method of a real stone paint spray gun with controllable atomization according to the above embodiment: Rotating the gear ring 49 causes all gears 48 to rotate synchronously, which in turn causes the gears 48 to rotate the worm gear 45, which in turn causes the worm gear 45 to move the rack 46 left and right. When the rack 46 moves left and right, it causes the adjusting sleeve 43 to move left and right. When the adjusting sleeve 43 moves left and right, it causes the valve core 44 to move left and right. The gap between the valve core 44 and the valve seat 42 changes, thereby making the flow rate of real stone paint through the valve core 44 controllably adjustable, so as to achieve the purpose of adjusting the atomization degree of the spray gun.

[0036] In the initial state, the ball groove 474 and the ball 472 are misaligned, so that the limiting ring 473 fixes the ball 472, preventing the ball 472 from moving. This causes the ball 472 to be locked in the groove, and the retaining ring 471 is fixed on the spray gun body 1. By rotating the limiting ring 473, the ball groove 474 is aligned with the ball 472, allowing the ball 472 to move. This allows the retaining ring 471 to be removed from the spray gun body 1, enabling quick assembly and disassembly.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of this application, and are not intended to limit them; although the embodiments of this application have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
