Description

Technical Field

[0001] The invention relates to the field of aerosol cans, in particular to a self-shaking aerosol spraying device for continuous spraying and a spraying method. Background Art

[0002] The aerosol can is composed of an aerosol can body, a nozzle, a bag valve and water-based latex paint.

[0003] When in use, place the water-based latex paint in the bag valve, and install the bag valve in the aerosol tank containing liquefied gas containing gas propellant, such as trichlorofluoromethane or dichlorodifluoromethane. When the button on the aerosol tank is pressed, the water-based latex paint becomes mist as the liquefied gas vaporizes and sprays out from the tank. This spraying method is called aerosol spraying. It is suitable for repairing small household items and small equipment and shells on transportation vehicles, etc. It is not suitable for large-scale continuous operations. At the same time, because the button needs to be pressed frequently during spraying, it is necessary to press the button and control the spraying speed during spraying, which greatly increases the difficulty of spraying and makes it difficult to control the spraying effect. Before spraying, the tank should be shaken vigorously to allow the stirring beads in the self-spraying paint to fully mix the paint. Summary of the invention

At the same time, under the action of the mounting board, on the one hand, the gas vaporization is ensured, and on the other hand, the gas is prevented from cooling due to long-distance movement, resulting in insufficient pressure in the aerosol tank;

[0036] By setting up a range changing component, the spray range of the nozzle can be increased when the pressure in the conduit is high, and vice versa, so that the spray range of the nozzle can be adaptively adjusted with the pressure in the conduit, and the spray range can be controlled by changing the pressure.

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0051] See also Figures 1 to 11 In an embodiment of the present invention, a self-shaking aerosol sprinkler device for continuous sprinkler irrigation includes: an aerosol tank 1, a mounting head 5, a driving mechanism, a two-way adjustment component, a blocking component and a range change component.

[0052] A connection kit is detachably installed in the aerosol can 1, and the connection kit is formed by a coaxially arranged connection piece 2, an agitator 3, and a bag valve 4, wherein the connection piece 2 and the agitator 3, and the agitator 3 and the bag valve 4 are sealed and rotatably connected, and a detachable connection method is adopted between the connection piece 2 and the aerosol can 1, and the detachable connection method includes, for example, a threaded connection or a snap connection, so as to facilitate the disassembly and cleaning of the connection kit;

[0053] The mounting head 5 is communicated with the bag valve 4 and is rotatably connected to the agitator 3. A conduit 25 communicating with the agitator 3 is provided on one side of the mounting head 5, and a blocking member 24 is movably provided inside the mounting head 5. The blocking member 24 is in the shape of a stepped shaft, and the mounting head 5 is fixedly connected to the connecting member 2.

[0054] When in use, gas is injected into the aerosol can 1, and the gas is specifically liquefied gas of trichlorofluoromethane or dichlorodifluoromethane. When the liquefied gas of trichlorofluoromethane or dichlorodifluoromethane is shaken, the molecules collide to generate heat, so that the trichlorofluoromethane or dichlorodifluoromethane is vaporized, thereby increasing the pressure in the aerosol can 1. Under the action of pressure, the water-based latex paint in the bag valve 4 can be squeezed out.

[0055] In the initial state, the blocking piece 24 can block one end of the conduit 25. When spraying is required, the blocking piece 24 is driven to move away from the conduit 25. Since the blocking piece 24 is in the shape of a stepped shaft, the amount of water-based latex paint flowing out of the conduit 25 per unit is different when the blocking piece 24 moves at different strokes. Therefore, during spraying, the spray amount of the water-based latex paint can be adjusted, making the spraying easier to control and improving the uniformity of the water-based latex paint after spraying.

[0056] Among them, a one-way valve is arranged on the mounting head 5, so that after the water-based latex paint in the bag valve 4 is used up, it can be replenished into the bag valve 4 through the one-way valve. Different from the existing aerosol can 1, the aerosol can 1 can be reused when in use to avoid material waste.

[0057] See also Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 The driving mechanism is arranged at the other side of the mounting head 5 and connected to the blocking member 24. The driving mechanism includes a transmission assembly and a power assembly. The power assembly can drive the blocking member 24 to periodically move toward or away from the conduit 25 through the transmission assembly.

[0058] The power assembly includes a mounting plate 6 fixedly mounted on one side of the mounting head 5, and two transmission wheels 8 are symmetrically arranged on the mounting plate 6, wherein the output shaft of one of the transmission wheels 8 passes through the mounting plate 6 and is connected to a driving device 7 fixed on the mounting plate 6, and a transmission belt 9 is sleeved between the two transmission wheels 8;

[0059] The power assembly further includes an interlocking structure penetrating the mounting head 5 and connected to the transmission belt 9, the interlocking structure including a follower 20 penetrating the mounting head 5, an interlocking groove 19 being formed at one end of the follower 20, an interlocking block 17 being slidably mounted in the interlocking groove 19, and the interlocking block 17 being rotationally connected to the transmission belt 9;

[0060] A connecting block is provided at one end of the blocking member 24, and the connecting block is slidably connected to a guide rod 44 provided in the mounting head 5;

[0061] The transmission assembly includes two follower plates 21 fixedly mounted on the connecting block. An inclined groove 22 is formed on the follower plate 21. Two protrusions 23 symmetrically mounted on the other end of the follower 20 can slide in the inclined groove 22.

[0062] When in use, the driving device 7 is controlled to work, and the output shaft of the driving device 7 will drive one of the transmission wheels 8 to rotate, and the transmission belt 9 sleeved between the two transmission wheels 8 will move. When the transmission belt 9 moves, it will drive the engaging block 17 to move, and the transmission belt 9 can be regarded as consisting of two circular segments and two straight segments. When the engaging block 17 moves to the circumferential segment of the transmission belt 9, the engaging block 17 will move in the engaging groove 19. In the process of continuous rotation of the transmission wheel 8, the engaging block 17 can be reciprocated and the follower 20 can be driven to reciprocate and rise and fall. At this time, the protrusion 23 will reciprocate and rise and fall, and the protrusion 23 slides in the inclined groove 22 on the follower plate 21, so that in the process of reciprocating and rising of the protrusion 23, the sealing member 24 can be driven by the follower plate 21 to periodically move toward or away from the conduit 25, and the stroke amount of the protrusion 23 rising and falling is constant, so that the stroke amount of each movement of the sealing member 24 is constant, so that the conduction amount of the conduit 25 is constant each time, that is, the amount of water-based latex paint extruded and sprayed is constant.

[0063] Through the above-mentioned arrangement, continuous periodic spraying of water-based latex paint can be achieved. Compared with the existing manual press spraying, on the one hand, the operation amount is reduced and the difficulty of operation during spraying is reduced. On the other hand, since the spraying amount of water-based latex paint is constant, the thickness of the water-based latex paint after spraying is more uniform and the spraying effect is better.

[0064] See also Figure 7 , Fig. 9 , the other transmission wheel 8 is connected to the tensioning structure arranged on the mounting plate 6, the tensioning structure includes a No. 1 slide groove 10 opened on the mounting plate 6, a vertical rod 11 is fixedly installed in the No. 1 slide groove 10, the vertical rod 11 is slidably connected with a No. 1 slider 13 slidably arranged in the No. 1 slide groove 10, and a No. 1 spring 12 is sleeved on the vertical rod 11, one end of the No. 1 spring 12 is connected to the end of the No. 1 slide groove 10, and the other end is connected to the No. 1 slider 13;

[0065] The first slider 13 is rotatably connected to one of the transmission wheels 8;

[0066] The bidirectional adjustment component is arranged on the mounting head 5, and the bidirectional adjustment component is connected with two tensioning wheels 18 that are rollingly matched with the power component. When the two tensioning wheels 18 are close to or away from each other, the driving stroke of the power component will increase or decrease;

[0067] The bidirectional adjustment assembly includes a No. 2 slide groove 14 arranged on the mounting plate 6 and perpendicular to the No. 1 slide groove 10, and two No. 2 sliders 15 are slidably installed in the No. 2 slide groove 14. The No. 2 sliders 15 are each provided with a threaded sleeve, and the threaded sleeve is threadedly matched with a bidirectional screw rod 16 rotatably installed in the No. 2 slide groove 14.

[0068] When in use, by rotating the bidirectional screw 16, the two threaded sleeves threadedly matched with the bidirectional screw 16 can be moved closer to or away from each other in the axial direction of the bidirectional screw 16 (the No. 2 slide 14 has a guiding effect on the No. 2 slider 15, and the No. 2 slider 15 is fixedly connected to the threaded sleeve, thereby preventing the threaded sleeve from rotating with the bidirectional screw 16). When the two threaded sleeves move away from each other, the two No. 2 sliders 15 will be driven to move away from each other, and the two tensioning wheels 18 will be driven to move away from each other, thereby moving the transmission belt 9 to the two ends. Side pulling, at this time, since the length of the transmission belt 9 is constant, when the two sides of the transmission belt 9 are pulled, the transmission wheel 8 connected to the No. 1 slider 13 will move toward the other transmission wheel 8. At this time, the No. 1 slider 13 compresses the No. 1 spring 12, thereby changing the length of the transmission belt 9 along the movement direction of the follower 20, so that the rising amplitude of the follower 20 decreases, thereby reducing the stroke of the protrusion 23 and the inclined groove 22 to drive the sealing member 24 to move, so that the maximum conduction amount of the conduit 25 is reduced, thereby reducing the amount of water-based latex paint sprayed in a single time.

[0069] Among them, since the above-mentioned bidirectional screw 16 and the threaded sleeve are connected by a thread, and the threaded connection has a self-locking property, after the external force is removed from the bidirectional screw 16, the position of the threaded sleeve will remain constant, thereby improving the stability of the device, and by controlling the conductance of the conduit 25, the spraying amount of water-based latex paint can be regulated, and can be adjusted according to actual needs, so that a more precise supply of water-based latex paint can be achieved during spraying.

[0070] It should be noted that the number of rotations of the bidirectional screw 16 should be based on the step thickness of the sealing member 24 within an integer. Taking the present invention as an example, the sealing member 24 is composed of three steps. After the bidirectional screw 16 is rotated a certain number of times, after the follower 20 rises to the maximum height, the sealing member 24 will protrude from the end of the conduit 25 by the thickness of one, two or three bosses.

[0071] See also Figure 2 , Figure 6 , Figure 8 The blocking component is arranged on the aerosol can 1, the blocking component is connected to the power component and is controlled by the two-way adjustment component. When the driving stroke of the power component increases, the blocking component can increase the collision degree of the gas in the aerosol can 1;

[0072] The output shaft of the driving device 7 is connected to a bevel gear set 34 rotatably mounted on the connecting member 2 through a belt 33, the bevel gear set 34 is connected to the stirring member 3, and a plurality of blades 32 are equidistantly arranged on the stirring member 3;

[0073] The blocking assembly includes a plurality of impact plates 31 rotatably mounted in the aerosol can 1, a first connecting rod 30 is rotatably mounted on the impact plates 31, and one end of the first connecting rod 30 away from the impact plates 31 is rotatably connected to a pull rod 29 movably arranged to penetrate the aerosol can 1;

[0074] The blocking assembly also includes a circular engaging member 28 fixedly connected to the end of the pull rod 29 away from the No. 1 connecting rod 30 and a lifting rod 26 fixedly installed on the No. 1 slider 13. A circular groove is provided in the circular engaging member 28, and a pulley 27 rotatably installed on the end of the lifting rod 26 away from the No. 1 slider 13 can roll in the circular groove.

[0075] When the driving device 7 is working, its output shaft will drive the agitator 3 to rotate through the belt 33 and the bevel gear set 34, so that the fan blades 32 on the agitator 3 rotate, and the fan blades 32 collide with the gas in the aerosol can 1 to vaporize the gas and generate pressure.

[0076] When the No. 1 slider 13 moves downward, the conduction of the conduit 25 decreases. At the same time, the No. 1 slider 13 drives the pulley 27 to move downward through the lifting rod 26. The pulley 27 is rollingly installed in the circular groove in the circular clamping member 28, so that the circular clamping member 28 is driven to move downward during the downward movement of the pulley 27. The circular clamping member 28 deflects the impact plate 31 through the No. 1 connecting rod 30, thereby reducing the rotation of the upper fan blade 32, driving the impact area between the gas in the aerosol tank 1 and the impact plate 31. At this time, the pressure generated in the aerosol tank 1 will also decrease synchronously, that is, the pressure in the aerosol tank 1 can follow the change of the discharge amount of the conduit 25.

[0077] Through the above arrangement, the pressure in the aerosol can 1 is matched with the storage amount of the conduit 25, so that the spraying amount of the water-based latex paint is easier to control, thereby further improving the spraying effect.

[0078] In the process of the rotation of the fan blade 32, the gas in the aerosol can 1 will circulate, and the gas will vaporize when colliding with the fan blade 32, the impact plate 31 and the bottom of the aerosol can 1. In order to better circulate the gas in the aerosol can 1, the fan blade 32 needs to be set at a higher height in the aerosol can 1. Although the higher height can circulate the gas in the aerosol can 1, the speed of the gas is slower when it reaches the bottom of the aerosol can 1, so that the impact force of the gas is smaller, resulting in insufficient gas vaporization, causing the pressure in the aerosol can 1 to be too low. By setting the impact plate 31, the gas interacts with the impact plate 31 before colliding with the bottom of the aerosol can 1, which ensures gas vaporization on the one hand and avoids cooling of the gas due to long-distance movement on the other hand, resulting in insufficient pressure in the aerosol can 1.

[0079] See also Figure 1 , Fig.10 , Fig.11 The range changing assembly is connected to the conduit 25, and an adjusting shield 41 is installed on the range adjusting assembly. The adjusting shield 41 cooperates with a nozzle 42 disposed at the end of the conduit 25 to change the spraying range of the nozzle 42;

[0080] The range changing assembly comprises a connecting sleeve 35 symmetrically arranged on both sides of the conduit 25, a piston disc 36 is sealingly and slidably installed in the connecting sleeve 35, the piston disc 36 is fixedly connected to a connecting rod 38 passing through the connecting sleeve 35, and a second connecting rod 39 is rotatably installed at one end of the connecting rod 38 away from the piston disc 36, the second connecting rod 39 is connected to a telescopic rod 40 connected to the adjustment shield 41 and passing through the outer shield 43, and the outer shield 43 is connected to the conduit 25;

[0081] A No. 2 spring 37 is sleeved in the connecting sleeve 35 . One end of the No. 2 spring 37 is connected to the piston disc 36 , and the other end is connected to the connecting sleeve 35 .

[0082] When in use, the water-based latex paint in the aerosol can 1 is squeezed into the conduit 25 by pressure and sprayed by the nozzle 42 on the conduit 25. In the initial state, there is no pressure in the conduit 25. At this time, if the nozzle 42 sprays the water-based latex paint, since the nozzle 42 is hemispherical, the water-based latex paint it sprays can be dispersed in a hemispherical shape. At this time, the water-based latex paint sprayed by the nozzle 42 will be blocked by the adjustable shield 41, so that the spray range of the nozzle 42 is smaller than the end of the large diameter of the outer shield 43. When the pressure in the conduit 25 increases, the piston disc 36 compresses the second spring 37, and drives the adjustable shield 41 to move away from the nozzle 42 through the connecting rod 38, the second connecting rod 39, and the telescopic rod 40, so that the spray range of the nozzle 42 is increased. At this time, the spray range of the nozzle 42 is affected by the diameter of the large diameter end of the outer shield 43 and the distance between the large diameter end of the outer shield 43 and the object to be sprayed.

[0083] Through the above arrangement, when the pressure in the conduit 25 is high, the spray range of the nozzle 42 increases, and vice versa, it decreases, so that the spray range of the nozzle 42 can be adaptively adjusted with the pressure in the conduit 25, so that the spray range can be controlled by changing the pressure.

[0084] As an embodiment of the present invention, a method for spraying using the device is also proposed, comprising the following steps:

[0085] Step 1: pouring water-based latex paint into the bag valve 4 through the one-way valve provided on the mounting head 5;

[0086] Step 2: According to the actual required spraying thickness or range, the driving stroke of the power component is adjusted by the bidirectional adjustment component, and the position state of the blocking component is changed at the same time, so that the pressure generated by the gas in the aerosol can 1 matches the actual required pressure;

[0087] Step 3: Start the power assembly, which will drive the blocking member 24 to move through the transmission assembly, so that the water-based latex paint in the bag valve 4 is intermittently squeezed out. At the same time, under the action of the nozzle 42, the water-based latex paint is squeezed out in the form of water mist. At this time, the nozzle 42 can be aimed at the area to be sprayed;

[0088] Step 4: The power component synchronously drives the agitator 3 to rotate, and under the action of the blocking component, the gases in the aerosol can 1 collide with each other to collide and generate pressure;

[0089] Step 5: When the water-based latex paint enters the conduit 25 to change the pressure in the conduit 25, the range changing component will change the distance between the regulating shield 41 and the nozzle 42, thereby changing the range of the nozzle 42 spraying the water-based latex paint.

[0090] To summarize, when in use, gas is injected into the aerosol can 1, and the gas is specifically liquefied gas of trichlorofluoromethane or dichlorodifluoromethane. When the liquefied gas of trichlorofluoromethane or dichlorodifluoromethane is shaken, the molecules collide to generate heat, so that the trichlorofluoromethane or dichlorodifluoromethane is vaporized, thereby increasing the pressure in the aerosol can 1. Under the action of pressure, the water-based latex paint in the bag valve 4 can be squeezed out.

[0091] In the initial state, the blocking piece 24 can block one end of the conduit 25. When spraying is required, the blocking piece 24 is driven to move away from the conduit 25. Since the blocking piece 24 is in the shape of a stepped shaft, the amount of water-based latex paint flowing out of the conduit 25 per unit is different when the blocking piece 24 moves at different strokes. Therefore, during spraying, the spray amount of the water-based latex paint can be adjusted, making the spraying easier to control and improving the uniformity of the water-based latex paint after spraying.

[0092] When in use, the driving device 7 is controlled to work, and the output shaft of the driving device 7 will drive one of the transmission wheels 8 to rotate, and the transmission belt 9 sleeved between the two transmission wheels 8 will move. When the transmission belt 9 moves, it will drive the engaging block 17 to move, and the transmission belt 9 can be regarded as consisting of two circular segments and two straight segments. When the engaging block 17 moves to the circumferential segment of the transmission belt 9, the engaging block 17 will move in the engaging groove 19. In the process of continuous rotation of the transmission wheel 8, the engaging block 17 can be reciprocated and the follower 20 can be driven to reciprocate and rise and fall. At this time, the protrusion 23 will reciprocate and rise and fall, and the protrusion 23 slides in the inclined groove 22 on the follower plate 21, so that in the process of reciprocating and rising of the protrusion 23, the sealing member 24 can be driven by the follower plate 21 to periodically move toward or away from the conduit 25, and the stroke amount of the protrusion 23 rising and falling is constant, so that the stroke amount of each movement of the sealing member 24 is constant, so that the conduction amount of the conduit 25 is constant each time, that is, the amount of water-based latex paint extruded and sprayed is constant.

[0093] When in use, by rotating the bidirectional screw 16, the two threaded sleeves threadedly matched with the bidirectional screw 16 can be moved closer to or away from each other in the axial direction of the bidirectional screw 16 (the No. 2 slide 14 has a guiding effect on the No. 2 slider 15, and the No. 2 slider 15 is fixedly connected to the threaded sleeve, thereby preventing the threaded sleeve from rotating with the bidirectional screw 16). When the two threaded sleeves move away from each other, the two No. 2 sliders 15 will be driven to move away from each other, and the two tensioning wheels 18 will be driven to move away from each other, thereby moving the transmission belt 9 to the two ends. Side pulling, at this time, since the length of the transmission belt 9 is constant, when the two sides of the transmission belt 9 are pulled, the transmission wheel 8 connected to the No. 1 slider 13 will move toward the other transmission wheel 8. At this time, the No. 1 slider 13 compresses the No. 1 spring 12, thereby changing the length of the transmission belt 9 along the movement direction of the follower 20, so that the rising amplitude of the follower 20 decreases, thereby reducing the stroke of the protrusion 23 and the inclined groove 22 to drive the sealing member 24 to move, so that the maximum conduction amount of the conduit 25 is reduced, thereby reducing the amount of water-based latex paint sprayed in a single time.

[0094] When the driving device 7 is working, its output shaft will drive the agitator 3 to rotate through the belt 33 and the bevel gear set 34, so that the fan blades 32 on the agitator 3 rotate, and the fan blades 32 collide with the gas in the aerosol can 1 to vaporize the gas and generate pressure.

[0095] When the No. 1 slider 13 moves downward, the conduction of the conduit 25 decreases. At the same time, the No. 1 slider 13 drives the pulley 27 to move downward through the lifting rod 26. The pulley 27 is rollingly installed in the circular groove in the circular clamping member 28, so that the circular clamping member 28 is driven to move downward during the downward movement of the pulley 27. The circular clamping member 28 deflects the impact plate 31 through the No. 1 connecting rod 30, thereby reducing the rotation of the upper fan blade 32, driving the impact area between the gas in the aerosol tank 1 and the impact plate 31. At this time, the pressure generated in the aerosol tank 1 will also decrease synchronously, that is, the pressure in the aerosol tank 1 can follow the change of the discharge amount of the conduit 25.

[0096] When in use, the water-based latex paint in the aerosol can 1 is squeezed into the conduit 25 by pressure and sprayed by the nozzle 42 on the conduit 25. In the initial state, there is no pressure in the conduit 25. At this time, if the nozzle 42 sprays the water-based latex paint, since the nozzle 42 is hemispherical, the water-based latex paint it sprays can be dispersed in a hemispherical shape. At this time, the water-based latex paint sprayed by the nozzle 42 will be blocked by the adjustment shield 41, so that the spray range of the nozzle 42 is smaller than the end of the large diameter of the outer shield 43. When the pressure in the conduit 25 increases, the piston disc 36 compresses the No. 2 spring 37, and drives the adjustment shield 41 to move away from the nozzle 42 through the connecting rod 38, the No. 2 connecting rod 39, and the telescopic rod 40, thereby increasing the spray range of the nozzle 42.
