[0026] Reference Figures 1 to 4 The three-proofing paint spraying device provided by the embodiments of the application can include a bottom plate 1, at least two liquid storage tanks 2, connecting pieces 3, iron blocks, moving pieces 5 and electromagnets 6. The bottom plate 1 has a first side and a second side oppositely arranged in a first direction, and the first direction is perpendicular to the bottom plate 1. The at least two liquid storage tanks 2 are arranged on the same side of the bottom plate 1 in a second direction, and the second direction is perpendicular to the first direction. The connecting pieces 3 are arranged on the side of the first side away from the second side and correspond to the liquid storage tanks 2 one by one.

[0027] The three-proofing paint spraying device provided by the embodiments of the application sets the new liquid storage tank 2 corresponding to the three-proofing paint on the bottom plate 1. The moving piece 5 moves to drive the electromagnet 6 to move synchronously, so that the electromagnet 6 contacts an iron block. The electromagnet 6 is powered on, so that the moving piece 5 can drive a connecting piece 3 to move. The water pump internally provided in the connecting piece 3 delivers the three-proofing paint in the corresponding liquid storage tank 2 to the nozzle 31 to be sprayed out. When it is necessary to replace the new three-proofing paint, the moving piece 5 is moved to the appropriate position, the electromagnet 6 is powered off, the corresponding iron block is separated from the electromagnet 6, the moving piece 5 starts to move to make the electromagnet 6 contact the iron block corresponding to the new three-proofing paint, the electromagnet 6 is powered on, so that the moving piece 5 can drive the connecting piece 3 corresponding to the new three-proofing paint and the nozzle 31 to move and spray. In this way, the operation of replacing the new three-proofing paint is fast, and it is not necessary to wait for the cleaning of the pipeline corresponding to the original three-proofing paint to be completed before the new spraying work is performed, so that the work efficiency is high.

[0028] Specifically, as shown in Figure 1

[0029] It should be understood that the water pump and the electromagnet 6 in the connecting piece 3 can be connected with an external power source, of course, a storage battery can also be built in the moving piece 5 and the connecting piece 3, and the water pump and the electromagnet 6 can be powered by the storage battery.

[0030] It should be noted that when the electromagnet 6 on the moving piece 5 is connected with the corresponding iron block, the moving piece 5 can be first moved above the iron block, at this time the moving piece 5 is moved downward so that the electromagnet 6 is in contact with the iron block, and then the electromagnet 6 is powered.

[0031] In addition, in the preferred embodiment, the number of liquid storage tanks 2 can be two, so that the three-proofing paint can be conveniently switched, and the spraying device has low cost.

[0032] Reference Figures 2 to 4 In the example embodiment, the three-proofing paint spraying device can further include a support 7, the support 7 is arranged on the side of the first side away from the second side and corresponds to the connecting piece 3 one by one, the side of the support 7 away from the bottom plate 1 is provided with a first containing groove 71 containing the connecting piece 3, and the first containing groove 71 is provided with a second containing groove 72 containing the nozzle 31; wherein the nozzle 31 is inserted into the second containing groove 72, and the connecting piece 3 is inserted into the first containing groove 71.

[0033] Specifically, when the iron block on the connecting piece 3 is not connected with the electromagnet 6 on the moving piece 5, the connecting piece 3 is inserted into the first containing groove 71, and the nozzle 31 is inserted into the second containing groove 72, so that the connecting piece 3 is conveniently placed.

[0034] Reference Figure 2 With Figure 3 In the example embodiment, the three-proofing paint spraying device can further include a cleaning tank 81 and a three-way valve 82, the cleaning tank 81 is arranged on the side of the first side away from the second side; the three-way valve 82 corresponds to the liquid storage tank 2 one by one, and the three-way valve 82 has two water inlets and one water outlet, wherein the two three-way valves 82 have one water inlet in communication with the cleaning tank 81, the other water inlet of the two three-way valves 82 is in communication with one liquid storage tank 2, and the water outlet of the two three-way valves 82 is in communication with the water pump built in the connecting piece 3 through the hose.

[0035] ​Specifically, the three-way valve 82 can switch which water outlet is in communication with which water inlet. Taking one three-way valve 82 and the pipeline connected thereto as an example, the nozzle 31 is in communication with the liquid storage tank 2 through the three-way valve 82. The nozzle 31 can be brought into communication with the cleaning tank 81 by switching the three-way valve 82. In this way, when a certain nozzle 31 and the hose connected thereto need to be cleaned, the corresponding three-way valve 82 is switched to bring the nozzle 31 into communication with the cleaning tank 81, and the corresponding water pump is started to clean the nozzle 31, which is more convenient.

[0036] Referring to Figure 2 With Figure 3 In the example embodiment, the connecting piece 3 extends out of the first containing groove 71 along the first direction X; wherein the connecting region of the hose and the connecting piece 3 is located on the side wall of the connecting piece 3 parallel to the first direction X.

[0037] It should be understood that if the connecting region of the hose and the connecting piece 3 is located above the connecting piece 3, the moving piece 5 moves from top to bottom, and the electromagnet 6 and the iron block can be blocked by the hose during the process of contacting each other. Therefore, the connecting region of the hose and the connecting piece 3 is arranged on the side wall of the connecting piece 3, so that the process of contacting the electromagnet 6 and the iron block is smoothly carried out, and the use is more convenient.

[0038] Referring to Figure 2 With Figure 3 In the example embodiment, the three-proof paint spraying device can further include a support table 11 fixed to one side of the first side away from the second side, wherein the liquid storage tank 2, the support piece 7 and the cleaning tank 81 are located on the side of the support table 11 away from the bottom plate 1.

[0039] Specifically, as Figure 2 shown, the liquid storage tank 2, the support piece 7 and the cleaning tank 81 are arranged on the support table 11, which can effectively prevent the hose between the connecting piece 3 and the three-way valve 82 from falling on the bottom plate 1 and affecting the three-proof paint spraying.

[0040] Referring to Figure 2 With Figure 3 In the example embodiment, the support piece 7 is provided with a third containing groove 73, and the first containing groove 71, the second containing groove 72 and the third containing groove 73 are arranged in sequence and in communication in the first direction X; the three-proof paint spraying device can further include a waste liquid barrel 91 and a connecting pipeline 92. The waste liquid barrel 91 is arranged between the support table 11 and the bottom plate 1, and the side of the waste liquid barrel 91 away from the bottom plate 1 is a barrel opening. The connecting pipeline 92 has at least two water inlets and one water outlet. The water inlets of the connecting pipeline 92 correspond to the support pieces 7 one by one. The water inlets of the connecting pipeline 92 penetrate through the support table 11 and the corresponding support pieces 7 and are in communication with the corresponding third containing grooves 73. The water outlet of the connecting pipeline 92 faces the barrel opening of the waste liquid barrel 91.

[0041] When the connector 3 is inserted into the first receiving groove 71, the nozzle 31 is inserted into the second receiving groove 72. The three-way valve 82 is switched to connect the nozzle 31 to the cleaning tank 81. At this time, the water pump is turned on, and the cleaning fluid cleans the nozzle 31. At the same time, the waste liquid after cleaning falls into the third receiving groove 73 and flows into the waste liquid tank 91 through the connecting pipe 92. In this way, when a nozzle 31 is not being sprayed and is inserted into the support 7, it can be cleaned, which is convenient and quick. It is also convenient to remove the waste liquid tank 91 from under the support table 11, which facilitates the unified treatment of waste liquid.

[0042] refer to Figure 2 and Figure 3 In an exemplary embodiment, at least two support members 7 are spaced apart in the second direction Y, and the support members 7, the cleaning tank 81, and the liquid storage tank 2 are arranged in sequence at intervals in the third direction Z. In an exemplary embodiment, the spraying device may further include a connecting hose 21, which corresponds one-to-one with the liquid storage tank 2 and connects the corresponding liquid storage tank 2 to the corresponding three-way valve 82, and the connecting hose 21 and the three-way valve 82 are detachably connected.

[0043] The two support members 7 are spaced apart in the second direction Y, so that the two hoses connected to the two connectors 3 are spaced apart in the second direction Y, preventing the two hoses connected to the two connectors 3 from tangling and overlapping when the moving member 5 moves one connector 3.

[0044] Furthermore, such as Figure 2 As shown, the support 7, cleaning tank 81, and liquid storage tank 2 are arranged in sequence at intervals along the third direction Z. Thus, the liquid storage tank 2 is located at the edge of the support table 11. The corresponding liquid storage tank 2 can be removed by disconnecting the connecting hose 21. The new liquid storage tank 2 and connecting hose 21 corresponding to the new conformal coating can be replaced. The replaced connecting hose 21 is then connected to the corresponding three-way valve 82, which facilitates the spraying of different types of conformal coatings.

[0045] It should be understood that before replacing the corresponding liquid tank 2 and connecting hose 21 with new conformal coating, the three-way valve 82 should be switched and the water pump turned on to clean the corresponding nozzle 31.

[0046] refer to Figure 2 and Figure 3 In an exemplary embodiment, the connector 3 is provided with a groove 32 on the side away from the base plate 1, the depth direction of which is the same as the first direction X. The cross section of the groove 32 perpendicular to the first direction X is non-circular. The iron block is fixed to the bottom of the groove 32. When the electromagnet 6 is inserted into the groove 32, the electromagnet 6 fits against the side wall of the groove 32 and abuts against the iron block.

[0047] Specifically, when the moving piece 5 moves above the connecting piece 3, the moving piece 5 moves from top to bottom and drives the electromagnet 6 to move along the first direction X and insert into the corresponding groove 32. When the electromagnet 6 contacts the iron block, the electromagnet 6 can be connected with the iron block by being powered. Thus, when the moving piece 5 moves, the corresponding connecting piece 3 can be synchronously moved.

[0048] Further, the cross section of the groove 32 perpendicular to the first direction X is non-circular. When the electromagnet 6 inserts into the groove 32, the electromagnet 6 is fitted with the side wall of the groove 32. Thus, when the moving piece 5 drives the connecting piece 3 to move, the relative position relationship between the connecting piece 3 and the moving piece 5 is fixed, so that the connecting piece 3 will not shake or rotate, and the spraying process is more stable.

[0049] Reference Figures 1 to 3 In the example embodiment, the side of the first side away from the second side is further provided with two first sliding grooves 12 extending along the third direction Z, and the two first sliding grooves 12 are spaced apart in the second direction Y.
