Description

Technical Field

[0001] The utility model relates to the technical field of spraying devices, in particular to a spraying device which is easy to clean. Background Art

[0002] With the rapid development of society, various applicable machines and equipment have evolved in the field of interior decoration, such as sprayers. Traditional interior decoration uses manual painting to apply putty on the wall, but now most people use spraying devices to apply putty, which has the advantages of high efficiency and labor saving.

[0003] During use of the existing spraying device, the putty in the spray tank is often pressed into the discharge pipe by compressed gas, and sprayed out through the nozzle on the discharge pipe, and then the putty is evenly sprayed on the wall by manually swinging the nozzle. However, the spraying device needs to be cleaned after the spraying operation is completed. The current cleaning method is basically to introduce water into the spray tank through the feed pipe, and then use the stirring device inside the spray tank to stir the water, so as to complete the cleaning of the spraying device. Since the original putty spray material has a large viscosity inside the spray tank, part of the putty spray material is easy to adhere to the inner wall of the spray tank, and the adhered putty spray material cannot be effectively cleaned by simply stirring the water flow, so that the adhered putty spray material will dry on the inner wall of the spray tank, thereby forming lumps mixed in the putty spray material to be sprayed next time, affecting the spraying effect.

[0012] An active cavity is provided inside the lower side of the rotating shaft;

[0014] The upper portion of the vertical rod extends into the active cavity, and a reciprocating thread is arranged on the outer surface of the vertical rod extending into the active cavity.

[0015] Preferably, the vertical rod includes:

[0016] A reciprocating magnetic slider, the transmission sleeve of which is connected to the outer surface of the vertical rod and is located at the reciprocating thread;

[0017] Limit rods, the number of which is two, the two limit rods are symmetrical with the vertical rod as the symmetry axis and are fixedly connected to the bottom surface of the inner cavity of the activity cavity;

[0018] The reciprocating magnetic slider is slidably sleeved with the limiting rod.

[0019] Preferably, the interior of the rotating shaft further includes:

[0020] An electromagnetic coil is fixedly arranged inside the rotating shaft and located at the outer circle of the active cavity;

[0022] Compared with the prior art, the utility model has the following beneficial effects:

[0023] 1. By designing a spiral strip at the top of the stirring rod, when the spray device needs to be cleaned after spraying, turn on the motor, use the motor to drive the rotating shaft and the stirring rod to rotate, and the stirring rod drives the spiral strip to rotate inside the spray tank. Since the outer surface of the spiral strip is in contact with the inner wall of the spray tank, the spiral strip will scrape off the spray material adhering to the inner wall of the spray tank during the rotation process, and the scraped spray material will be mixed with the cleaning water in the spray tank and finally taken away by the cleaning water, which effectively prevents the spray material from adhering to the inner wall of the spray tank and improves the cleaning effect of the spray device.

[0024] 2. By designing the movable cavity, vertical rod, reciprocating thread, reciprocating magnetic slider and electromagnetic coil, when the spray tank is cleaned, the motor will drive the rotating shaft to rotate. At this time, the reciprocating thread on the vertical rod is used in conjunction with the limit rod to make the reciprocating magnetic slider do up and down reciprocating motion inside the movable cavity, so that the up and down reciprocating motion of the reciprocating magnetic slider is used in conjunction with the electromagnetic coil to form an electromagnetic effect, so that the electromagnetic coil generates current. Since the electromagnetic coil is connected to the heating wire through a wire, the current generated by the electromagnetic effect of the electromagnetic coil will be transmitted to the heating wire, causing the heating wire to heat up, so that the heating wire is used to heat the cleaning water in the spray tank, so that the spray material attached to the inner wall of the spray tank can be accelerated to merge with the cleaning water, further improving the cleaning effect of the spray device.

[0025] 3. When the spray device is performing the spraying operation, the heating energy of the electric heating wire can increase the fluidity of the spray material inside the spray tank. At this time, in conjunction with the rotation of the stirring rod and the spiral strip, the uniformity of the mixing of the spray material in the spray tank is improved, thereby improving the spraying effect of the spray material.

The electric heating wire 82 is used to heat the cleaning water to accelerate the mixing of the spray material and the cleaning water. Secondly, the electric heating wire 82 can be used to heat the spray material during the spraying operation, thereby increasing the fluidity of the spray material and improving the spraying effect.

[0036] See also Figure 1-Figure 5 A movable cavity 71 is provided inside the lower side of the rotating shaft 7, and a vertical rod 72 is fixedly welded to the middle of the bottom surface of the inner cavity of the spray tank 3.

[0037] The upper portion of the vertical rod 72 extends into the movable cavity 71 , and a reciprocating thread 73 is provided on the outer surface of the vertical rod 72 extending into the movable cavity 71 .

[0038] See also Figure 1-Figure 5 The outer surface of the vertical rod 72 is located at the reciprocating thread 73 and the transmission sleeve is connected with a reciprocating magnetic slider 74 to ensure that when the shaft 7 rotates, the reciprocating magnetic slider 74 will be driven to reciprocate up and down along the reciprocating thread 73 on the vertical rod 72.

[0043] Working principle: When the spraying device is normally performing the spraying operation, the spray material is put into the spray tank 3 through the feed port 4, and then the motor 6 is turned on. The motor 6 drives the rotating shaft 7 and the stirring rod 8 to rotate, and the stirring rod 8 is used to stir the spray material. The stirred spray material is transmitted through the discharge pipe 5 and sprayed at the nozzle.

When the inside of the spray tank 3 needs to be cleaned, the spiral strip 81 is driven to rotate by the rotating shaft 7 and the stirring rod 8, and the outer surface of the spiral strip 81 is in contact with the inner wall of the spray tank 3. The spray material adhering to the inner wall of the spray tank 3 is scraped off by the rotating spiral strip 81, and the scraped spray material will be taken away by the cleaning water in the spray tank 3. Secondly, the heat of the heating wire 82 will heat the cleaning water in the spray tank 3, and the scraped spray material will accelerate the mixing of the spray material and the cleaning water after contacting with the heated cleaning water, thereby improving the cleaning effect of the spray device.
