DETAILED DESCRIPTION

[0045] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0046] As described in the background, in the current decoration scene, a paint spray gun is usually used as a paint brushing device. However, the flowability of paint in the spray gun will decrease due to factors such as environmental changes, standing time and use mode, resulting in thickening or even solidification of the paint, which not only affects the construction efficiency, but also may cause the spray gun to be blocked, so that it is difficult to smoothly spray the paint when used again.

[0047] Based on this, the present application provides a paint spray gun for house construction, aiming to solve the technical problems of poor flowability and easy solidification of paint in the prior art.

[0048] Reference Figure 1 and Figure 2 The paint spray gun of the present application is specifically a handheld small spray gun, which generally comprises: a gun body 30 as the main body structure of the spray gun, for spraying paint; a storage body 10 for storing paint and providing paint to the gun body 30; a first stirring mechanism 20 for stirring the paint in the storage body 10 to make the paint flow; and a second stirring mechanism 40 also for stirring the paint in the storage body 10 to make the paint flow, but the stirring mode of the second stirring mechanism 40 is different from that of the first stirring mechanism 20.

[0049] The structure of the spray gun of the present application will be specifically analyzed below with reference to the drawings of the specification, Figure 1 and Figure 2The utility model provides a paint spraying gun for house construction, which comprises a storage body 10 for storing paint, a first stirring mechanism 20 comprising a rod body 200 and a plurality of blades 210, the rod body 200 being arranged through the storage body 10, and the blades 210 being arranged along the length direction of the rod body 200 and configured to stir the paint as the rod body 200 rotates, and a gun body 30 connected to the storage body 10 and configured to perform a buffering operation on the stirred paint before spraying it to a designated position.

[0050] By arranging the first stirring mechanism 20, i.e., the combination of the rod body 200 and the blades 210, in the storage body 10, the paint can be continuously stirred to prevent the paint from thickening or solidifying due to being in a non-flowing state, thereby avoiding the problems of clogging of the spraying gun and uneven spraying. In addition, the gun body 30 sprays the paint after performing a buffering operation on it, effectively reducing the accumulation of paint at the spray head and further improving the reliability of the spraying gun and the uniformity of the spraying. In this way, the construction efficiency is improved, the maintenance period of the spraying gun is prolonged, and the downtime caused by replacement of paint due to solidification of the paint is reduced.

[0051] In a specific embodiment, as shown in Figure 1 and Figure 2 , the storage body 10 is in the shape of a barrel-shaped cylinder with an opening at the top, through which the gun body 30 is connected to the lower part of the storage body 10.

[0052] In a specific embodiment, as shown in Figure 1 and Figure 2 , the rod body 200 is arranged through the inside of the storage body 10 along the height direction of the storage body 10, and the blades 210 are arranged along the length direction of the rod body 200 and are divided into two sides of the rod body 200 in the transverse direction; each blade 210 and the rod body 200 have a preset included angle therebetween to improve the stirring efficiency of the paint.

[0053] In a specific embodiment, the spraying gun controls the spraying speed and thickness of the paint by adjusting the pressure of the compressed air provided by the air flow mechanism, thereby achieving the buffering operation of the paint and improving the spraying efficiency and quality.

[0054] Preferably, referring to Figure 1 and Figure 2 , the first stirring mechanism 20 further comprises a first driving member 220 connected to the rod body 200 and arranged at the top end of the storage body 10 and configured to drive the rod body 200 to rotate.

[0055] In a specific embodiment, as shown in Figure 1 and Figure 2As shown, the first driving member 220 adopts a driving motor, the main body of the driving motor is arranged at the top end of the storage body 10, the output shaft faces the inside of the storage body 10, and is connected with the rod body 200. When the driving motor is started, the output shaft drives the rod body 200 to rotate synchronously, and then the blade 210 stirs the paint.

[0056] In a specific embodiment, as shown in Figure 1 and Figure 2 , the number of the first driving member 220 is two, both of which adopt driving motors, and the two motors work simultaneously to drive the rod body 200 to rotate.

[0057] Preferably, the number of the first stirring mechanism 20 is multiple, and the rod bodies 200 of different first stirring mechanisms 20 have different rotating directions, or all the rod bodies 200 have the same rotating direction.

[0058] Among them, the arrangement of multiple first stirring mechanisms 20 can improve the stirring efficiency of the paint. In one case, when the rod bodies 200 of the first stirring mechanisms 20 have different rotating directions, three-dimensional stirring of the paint can be more effectively realized, the flowability of the paint is increased, and thus the solidification of the paint is more effectively prevented. In another case, when the rod bodies 200 of all the first stirring mechanisms 20 have the same rotating direction, the design and control of the first stirring mechanism 20 can be simplified, the complexity of the control system is reduced, the stirring is more regular, and thus the control and maintenance are facilitated, and the flowability of the paint can also be ensured. In summary, different rotating directions and the same rotating direction both have their advantages in technology, and in actual application, they can be selected according to the construction requirements and stirring effect.

[0059] Preferably, referring to Figure 1 and Figure 2 , the spray gun further comprises a second stirring mechanism 40, which comprises a pushing member 400 arranged inside the storage body 10 in a direction away from the first stirring mechanism 20 and configured to reciprocate along a preset direction to push the paint.

[0060] Among them, the pushing member 400 reciprocates to further push the paint, so as to ensure that the paint is always in a flowing state in the storage body 10. In addition, the reciprocating movement of the second stirring mechanism 40 and the rotating force of the first stirring mechanism 20 are combined, which enhances the stirring effect of the paint and makes the flowability of the paint stronger.

[0061] In a specific embodiment, as shown in Figure 1 and Figure 2 , the pushing member 400 is a rectangular plate located directly below the two rod bodies 200 and can move along the direction close to or away from the rod bodies 200 to push the paint.

[0062] Preferably, referring to Figure 1 andFigure 2 The second stirring mechanism 40 further comprises a second driving member 410 connected to the pushing member 400 and arranged at the bottom end of the storage body 10 and configured to drive the pushing member 400 to move; the pushing member 400 has a preset distance from the end of the rod body 200 when the pushing member 400 moves to the maximum distance.

[0063] In a specific embodiment, as shown in Figure 1 and Figure 2 , the second driving member 410 is a pneumatic cylinder, the main body of the pneumatic cylinder is arranged at the bottom end of the storage body 10, the output shaft is connected to the pushing member 400, and when the pneumatic cylinder is started, the output shaft drives the pushing member 400 to move in the direction of approaching the rod body 200 to the maximum distance, and the pushing member 400 and the rod body 200 still have a preset distance therebetween, so as to prevent the stirring mechanism from being damaged due to the pushing member 400 touching the rod body 200 when the moving distance of the pushing member 400 is too large.

[0064] Preferably, referring to Figure 2 , the spray gun further comprises an upper shell 50 connected to the top end of the storage body 10 and used for covering the first driving member 220, and a lower shell 60 connected to the bottom end of the storage body 10 and used for covering the second driving member 410.

[0065] The first driving member 220 and the second driving member 410 are protected by the upper and lower shells when working, the interference of the external environment on the driving members is avoided, and the reliability of the spray gun in working is improved.

[0066] In a specific embodiment, as shown in Figure 2 , the upper shell 50 and the lower shell 60 are threadedly and rotatably detachably connected to the storage body 10, so that when the first driving member 220 or the second driving member 410 fails, the upper and lower shells can be detached for timely maintenance.

[0067] Preferably, referring to Figure 1 , the gun body 30 comprises a containing cavity 300 configured to store the paint sucked from the storage body 10, a communication structure 310 having one end connected to the containing cavity 300 and the other end connected to the storage body 10 and configured to allow the paint to pass through, and an airflow mechanism connected between the containing cavity 300 and the storage body 10 and configured to generate airflow and use the suction force of the airflow to suck the paint from the storage body 10 into the containing cavity 300.

[0068] The airflow mechanism generates airflow, and uses the suction force generated by the airflow to suck the paint from the storage body 10 into the containing cavity 300, so as to ensure the flowability of the paint when the paint is transferred from the storage body 10 to the containing cavity 300, so as to facilitate subsequent spraying operation, and improve the continuity and uniformity of the spraying of the spray gun.

[0069] In a specific embodiment, as shown in Figure 1 andFigure 2 As shown, the storage body 10 comprises a pipeline 100, one end of which passes through the upper shell 50 and is connected to the accommodating cavity 300 through the communication structure 310, and the other end extends towards the inside of the storage body 10. When the airflow mechanism works to generate negative pressure, the paint in the storage body 10 flows through the pipeline 100 and the communication structure 310 into the accommodating cavity 300, preparing for subsequent spraying operation.

[0070] Preferably, referring to Figure 1 and Figure 3 , the gun body 30 further comprises an atomization mechanism 320 in communication with the accommodating cavity 300, and a buffer structure 330 comprising a straight member 3300 and a spiral member 3310, the spiral member 3310 being wound around the straight member 3300 and configured to slow down the flow speed of the paint sucked to the atomization mechanism 320.

[0071] As the paint is in a rotating flow state in the storage body 10, when the paint enters the accommodating cavity 300 from the storage body 10, it still has an initial speed, so the buffer structure 330 is used to reduce the flow speed of the paint to the atomization mechanism 320, so as to reduce the turbulence and splashing of the paint due to the flow at a certain speed, thereby improving the uniformity and quality of the spraying. The design of the spiral member 3310 wound around the straight member 3300 causes the paint to be continuously disturbed when passing through, which helps to maintain the fluidity of the paint while slowing down the flow speed of the paint, reduces the dynamic changes in the flow of the paint, thereby avoiding the uneven phenomenon that may occur in the spraying process. At the same time, the atomization mechanism 320 cooperates with the airflow mechanism to suck the paint from the storage body 10 into the accommodating cavity 300 by the airflow suction generated by the airflow mechanism, and then adjusts it through the buffer structure 330, so as to ensure that the paint has a suitable flow rate and pressure when it reaches the atomization mechanism 320, so as to achieve better atomization effect.

[0072] Preferably, referring to Figure 1 , the atomization mechanism 320 comprises a needle valve (not shown in the figure) connected to the accommodating cavity 300 and configured to open or block the passage of the paint to adjust the flow rate of the paint, a nozzle (not shown in the figure) connected to the needle valve and configured to spray the paint, and an air cap (not shown in the figure) surrounding the nozzle and configured to atomize the paint into a preset spray shape.

[0073] In a specific embodiment, in the spraying process, the paint is first sucked from the storage body 10 into the accommodating cavity 300 by the airflow mechanism, then the flow rate is adjusted by the needle valve, the needle valve opens or blocks the passage of the paint to control the flow rate of the paint, then the adjusted paint flows to the nozzle connected to the needle valve, the nozzle sprays the paint, at the same time, the air cap atomizes the sprayed paint into a preset spray shape by using high-speed airflow, achieving uniform spraying and improving the quality and efficiency of the spraying operation.

[0074] Preferably, the gun body 30 further comprises a trigger 340 configured to control the opening degree of the needle valve; and a transmission rod (not shown in the figure) connected between the trigger 340 and the needle valve.

[0075] In a specific embodiment, when the trigger 340 is pulled by the worker, the trigger 340 drives the transmission rod to move in a first direction, and the transmission rod drives the needle valve to move in the first direction to expand the paint flow passage and increase the paint flow rate; when the trigger 340 is released by the worker, the trigger 340 drives the transmission rod to move in a second direction, and the transmission rod drives the needle valve to move in the second direction to reduce the paint flow passage and decrease the paint flow rate; wherein the first direction and the second direction are opposite.

[0076] Preferably, the gun body 30 further comprises an air valve rod 350 connected with the trigger 340 and configured to move with the trigger 340 to control the flow rate of the compressed air generated by the air flow mechanism.

[0077] In a specific embodiment, when the trigger 340 is pulled by the worker, the air valve rod 350 is pressed to expand the air flow passage and increase the flow rate of the compressed air; when the trigger 340 is released by the worker, the air valve rod 350 returns to the initial position to reduce the air flow passage and decrease the flow rate of the compressed air.

[0078] Preferably, referring to Figure 1 , the gun body 30 further comprises a handle portion 360 configured to be held by the user to pick up the gun body 30.

[0079] In a specific embodiment, the worker holds the handle portion 360 with one hand, places the fingers on the trigger 340, and holds the gun body 30 with the other hand to perform the wall painting operation.

[0080] Preferably, the spray gun further comprises a shielding mechanism (not shown in the figure) sleeved on the outer wall surface of the gun body 30 in a direction close to the atomization mechanism 320 and configured to shield the splashed paint points during the painting operation.

[0081] Wherein, the worker may be splashed with paint during the painting operation, and the shielding mechanism is provided to shield the splashed paint during the painting operation of the spray gun, thereby avoiding the influence of the paint on the worker.

[0082] In a specific embodiment, the shielding mechanism is a transparent baffle, the baffle is in the form of a radial ring, the side cross-section is in the form of an isosceles trapezoid, and the baffle is sleeved on the outer wall surface of the gun body 30.
