Description

Technical Field

[0001] The utility model belongs to the field of spraying equipment, and relates to a portable backpack type lithium battery spraying machine, in particular to a portable backpack type plunger type high pressure airless spraying machine. Background Art

[0002] For waterproofing of walls, waterproof materials are usually sprayed on the walls evenly by high-pressure airless sprayers. High-pressure airless sprayers have the characteristics of high production efficiency, fast spraying speed, less paint mist during operation, and good coating quality. High-pressure airless sprayers use high-pressure pumps to press the paint to a certain pressure and then spray it out through a special nozzle hole. As the impact air and pressure drop sharply, the solvent evaporates rapidly, the volume of the paint suddenly expands and disperses into atomization, and is sprayed onto the surface of the workpiece at high speed. Because the paint atomization does not use compressed air, it is called high-pressure airless spraying.

[0003] The existing spraying machine lower barrel is set at the bottom, and the negative pressure adsorption is generated. The spraying pressure and reflux need to be repeatedly adjusted during the spraying process, and the spraying efficiency is low. Utility Model Content

[0004] In view of this, the utility model provides a portable backpack type lithium battery sprayer to solve the problem that the existing sprayer needs to repeatedly adjust the spraying pressure and reflux during the spraying process, resulting in low spraying efficiency.

[0005] In order to achieve the above object, the utility model provides the following technical solutions:

[0006] A handbag-type lithium battery sprayer includes a fuselage, a discharge barrel located above the fuselage, a motor at the rear end of the fuselage, and a booster chamber at the front end of the fuselage. A plunger used in conjunction with the telescopic rod of the motor is provided in the fuselage. The motor is electrically connected to a battery. One end of the plunger is fixedly connected to the telescopic rod of the motor, and the other end is connected to a discharge port that passes through the booster chamber. Beneficial effect: The telescopic rod of the motor moves back and forth, driving the plunger to move back and forth, pushing the paint to the discharge port for spraying. A regulating valve is provided on one side of the booster chamber, and a safety valve is provided on the side of the booster chamber opposite to the regulating valve. Beneficial effect: The spraying pressure of the discharge port is controlled by the regulating valve; when the spraying pressure exceeds the set pressure, the pressure is released through the safety valve to control the spraying pressure within a safe range.

[0007] Furthermore, the battery is a lithium battery.

[0008] Furthermore, a shell is mounted on the outer body of the machine, a handle is movably connected to the shell, and the handle is connected to the shell through a screw.

[0009] Furthermore, a switch electrically connected to the motor is provided on the housing. Beneficial effect: the start or stop of the motor is controlled by the switch.

[0010] Furthermore, foot pads are provided at the four corners of the bottom of the shell.

[0011] Furthermore, corresponding positions on both sides of the shell are provided with rope buckles. Beneficial effect: the back rope passes through the rope buckle to realize that the sprayer can be carried outside.

[0012] Furthermore, the discharge port is externally connected with a hose, and the hose is connected with a nozzle.

[0013] The beneficial effects of the utility model are:

[0014] 1. The portable backpack lithium battery sprayer disclosed by the utility model has a high spraying efficiency after the motor is started and the telescopic rod drives the plunger to move back and forth.

Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on the present invention. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0025] like Figure 1-Figure 3 A handbag-type lithium-ion sprayer is shown, in which the paint spraying operation direction is defined as the front end of the fuselage 2, including the fuselage 2, a discharge barrel 6 located above the fuselage 2, a motor 3 at the rear end of the fuselage 2 and a booster bin 7 at the front end of the fuselage 2. The fuselage 2 is covered with an outer shell 1, the motor 3 is electrically connected to a lithium battery 4 arranged outside the outer shell 1, and a switch 5 electrically connected to the motor 3 is arranged on the outer shell 1. A plunger (the plunger is a commonly used component in this field) is arranged in the fuselage 2, one end of the plunger is fixedly connected to the telescopic rod of the motor 3, and the other end is connected to a discharge port 13, and the discharge port 13 passes through the booster bin 7. When the motor 3 is started, the telescopic rod moves back and forth, driving the plunger to move and push the paint to the discharge port 13.

[0026] A regulating valve 8 is provided on one side of the boosting bin 7, which can adjust the pressure of the spraying at the discharge port 13. Before the spraying operation, the spraying pressure is adjusted by the regulating valve 8. A safety valve 9 is provided on the side of the boosting bin 7 opposite to the regulating valve 8. When the spraying pressure exceeds the set pressure, the pressure is released through the safety valve 9 to control the spraying pressure within a safe range.

[0027] A handle 10 is movably connected to the shell 1 through a screw rod 11, and the handle 10 is provided for easy carrying. Foot pads 12 are provided at the four corners of the bottom of the shell 1, and rope buckles 14 are provided at corresponding positions on both sides of the shell 1. The back rope passes through the rope buckles 14 so that the operator can carry the sprayer on his back.

[0028] The boosting chamber 7 is externally connected with a hose, and the hose is connected with a nozzle.

[0029] When the handbag-type lithium-ion sprayer is used, the spraying pressure is adjusted in advance through the regulating valve 8 according to the working conditions, the paint is put into the lower barrel 6, the motor 3 is started through the switch 5, and the telescopic rod of the motor 3 drives the plunger to move back and forth. The plunger pushes the paint to the discharge port 13, and the paint is sprayed out through the hose and the nozzle. When the spraying pressure is too high, the pressure is released through the safety valve 9 to control the pressure. After the spraying operation is completed, the switch 5 is pressed to shut down the motor 3, and the lithium battery 4 can be replaced at any time.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
