It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0049] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0050] like Figure 1 FIG. 1 is a schematic structural diagram of a paint spray atomizing device according to an embodiment of the present invention, comprising:

[0051] Motor housing 1;

[0052] A separation sleeve 2, wherein the separation sleeve 2 is fixed in the motor housing 1;

[0053] A first fixing plate 4, wherein the first fixing plate 4 is fixed in the separation sleeve 2;

[0054] an external rotating cup 5, wherein the external rotating cup 5 is rotatably connected to the first fixed plate 4;

[0055] The inner rotating cup 6 is arranged in the outer rotating cup 5;

[0056] A side through hole 7, wherein the side through hole 7 is provided on the peripheral side of the inner rotating cup 6;

[0057] A paint supply pipe 8, which is rotatably connected to the outer rotating cup 5 and fixedly connected to the inner rotating cup 6;

[0058] The paint supply pipe 8 is connected to the outer rotating cup 5 via a turbulent rotation connection mechanism 100, and the paint supply pipe 8 is connected to a potential energy conversion mechanism 200 that drives the paint supply pipe 8 to rotate.

[0059] The paint supply pipe 8 is connected to a paint supply mechanism for supplying paint thereto.

[0060] In an embodiment of the present invention, when in use, air is supplied to the potential energy conversion mechanism 200, and the potential energy conversion mechanism 200 converts the potential energy of the compressed air into mechanical energy to drive the paint supply tube 8 to rotate, and the paint supply tube 8 drives the inner rotating cup 6 to rotate. The inner rotating cup 6 uses centrifugal action to throw the paint inside it out from the side through hole 7, and the paint collides with the inner wall of the outer rotating cup 5, thereby being atomized. At the same time, compared with the traditional atomization device, the paint supply tube 8 in this device drives the outer rotating cup 5 to rotate in the opposite direction through the turbulent rotation connection mechanism 100. Since the outer rotating cup 5 and the inner rotating cup 6 rotate in opposite directions, the force between the outer rotating cup 5 and the paint is greater, thereby enhancing the paint atomization effect.

[0061] In one case of this embodiment, the paint supply mechanism includes a rotary joint and a paint supply assembly. The output end of the paint supply assembly is connected to the rotary joint. The rotary joint is installed on the paint supply pipe 8. The rotary joint can supply paint to the paint supply pipe 8 while it rotates.

[0062] like Figure 1 As shown in FIG. 1 , as a preferred embodiment of the present invention, the chaotic rotation connection mechanism 100 includes:

[0063] A second fixing plate 9, which is fixed in the separation sleeve 2 and is rotatably connected to the paint supply pipe 8;

[0064] A rotating shaft 10, the rotating shaft 10 is rotatably disposed on the second fixing plate 9;

[0065] A first external gear 11, wherein the first external gear 11 is mounted on the paint supply tube 8;

[0066] a second external gear 12 , which is mounted on the rotating shaft 10 and meshes with the first external gear 11 ;

[0067] an internal gear 13, wherein the internal gear 13 is meshedly connected with the second external gear 12;

[0068] The connecting rod 14 is fixedly connected to the outer wall of the outer rotating cup 5 and the end face of the inner gear 13 .

[0069] In an embodiment of the utility model, when in use, the paint supply tube 8 drives the first outer gear 11 to rotate, the first outer gear 11 drives the second outer gear 12 to rotate in the opposite direction, 12 drives the inner gear 13 to rotate in the same direction, and the inner gear 13 drives the outer rotating cup 5 to rotate in the same direction through the connecting rod 14. The outer rotating cup 5 thus rotates in the opposite direction to the inner rotating cup 6, so that the atomization effect of the paint colliding with the inner wall of the outer rotating cup 5 is better.

[0070] In one aspect of this embodiment, the chaotic rotation connection mechanism 100 includes:

[0071] A second fixing plate 9, which is fixed in the separation sleeve 2 and is rotatably connected to the paint supply pipe 8;

[0072] A rotating shaft 10, the rotating shaft 10 is rotatably disposed on the second fixing plate 9;

[0073] A first gear pair, the first gear pair being connected to the rotating shaft 10 and the paint supply pipe 8;

[0074] The second gear pair is connected to the rotating shaft 10 and the outer rotating cup 5.

[0075] In this embodiment, the paint atomization effect can also be increased by the direction of the same-direction differential speed, that is, the rotational speed of the external rotating cup 5 is different from the rotational speed of the paint supply tube 8. The speed difference between the two makes the atomization effect of the paint colliding with the inner wall of the external rotating cup 5 better.

[0076] like Figure 1 As shown, as another preferred embodiment of the present invention, the potential energy conversion mechanism 200 includes:

[0077] A support base 15, the support base 15 is rotatably connected to the paint supply pipe 8;

[0078] A driving cavity 16 is provided on the peripheral side of the support seat 15;

[0079] A rebound assembly, the rebound assembly being evenly fixed to the peripheral side of the support base 15 located in the driving cavity 16;

[0080] A first air inlet pipe 19 , one end of which is connected to a first air supply mechanism for supplying air thereto, and the other end of which is in communication with the driving chamber 16 .

[0081] In the embodiment of the present invention, air is supplied to the first air inlet pipe 19 through the first air supply mechanism, and compressed air is ejected from the first air inlet pipe 19 into the driving chamber 16, thereby acting on the rebound component, and the rebound component drives the paint supply pipe 8 to rotate.

[0082] In one aspect of this embodiment, the rebound component includes:

[0083] A fixing ring 17 is evenly fixed to the circumference of the support base 15 located in the driving cavity 16;

[0084] The fan plate 18 is fixedly connected to the fixing ring 17 .

[0085] In this embodiment, the first air inlet pipe 19 can also be opposed by an inclined end surface. The effective area of this structure is not as large as that of the above solution.

[0086] like Figure 1As shown, as another preferred embodiment of the present invention, the device further includes:

[0087] A sealing seat 3, wherein the sealing seat 3 is fixedly connected to the inner wall of the opening side of the motor housing 1 and the end surface of the separation sleeve 2;

[0088] A guide air jet hole 22 is provided in the sealing seat 3 and faces between the side through hole 7 and the inner wall of the outer rotating cup 5;

[0089] The cavity between the motor housing 1 and the separation sleeve 2 is connected to a second air supply mechanism.

[0090] In the embodiment of the present invention, air is supplied to the cavity between the motor housing 1 and the separation sleeve 2 through the second air supply mechanism, and the gas is ejected from the guide jet hole 22 on the sealing seat 3, thereby colliding with the paint ejected from the side through hole 7, thereby increasing the atomization effect.

[0091] In one aspect of this embodiment, the air supply mechanism includes a second air inlet pipe 21 , and the second air inlet pipe 21 is connected to the first air supply mechanism.

[0092] In one case of this embodiment, the potential energy conversion mechanism 200 also includes a connecting pipe 20, one end of which is connected to the cavity between the motor housing 1 and the separation sleeve 2, and the other end of the connecting pipe 20 is connected to the drive chamber 16. The residual compressed air is used to replenish the cavity between the motor housing 1 and the separation sleeve 2, thereby increasing the pressure rise rate.

[0093] In one case of this embodiment, the connecting pipe 20 is tilted, and one end of the connecting pipe 20 connected to the separation sleeve 2 is close to the guide injection hole 22. This arrangement allows the initial direction of the flow to be toward the guide injection hole 22, thereby enhancing diffusion efficiency.

[0094] In one case of this embodiment, the first air supply mechanism, the second air supply mechanism, and the third air supply mechanism can all supply air through the same compressed air system.

[0095] The above embodiment of the present invention provides a paint spray atomization device, which is provided by arranging a motor housing 1, a separation sleeve 2, an outer rotating cup 5, an inner rotating cup 6, a side through hole 7, a paint supply pipe 8, a turbulent rotation connection mechanism 100 and a potential energy conversion mechanism 200. When in use, air is supplied to the potential energy conversion mechanism 200, and the potential energy conversion mechanism 200 converts the potential energy of the compressed air into mechanical energy to drive the paint supply pipe 8 to rotate. The paint supply pipe 8 drives the inner rotating cup 6 to rotate, and the inner rotating cup 6 is centrifugal. The paint inside the inner rotating cup is thrown out from the side through hole 7, and the paint collides with the inner wall of the outer rotating cup 5, thereby being atomized. At the same time, compared with the traditional atomization device, the paint supply pipe 8 in this device drives the outer rotating cup 5 to rotate in the opposite direction through the turbulent rotation connection mechanism 100. Since the outer rotating cup 5 and the inner rotating cup 6 rotate in opposite directions, the force between the outer rotating cup 5 and the paint is greater, thereby enhancing the paint atomization effect.
