Technical Field

[0001] This utility model relates to the field of sprayer technology, specifically a cleaning sprayer for cleaning services. Background Technology

[0002] A sprayer is short for spraying equipment. A sprayer is a device that uses air suction to turn chemicals or other liquids into a mist and spray it evenly onto other objects. Usually, during the cleaning service process, it is necessary to spray cleaning agents on the areas that need to be cleaned. When spraying cleaning agents, a cleaning service sprayer is needed.

[0003] The existing technology has the following problems:

[0004] When spraying cleaning agents, the agent is usually squeezed out by pressing the handle. The amount of cleaning agent sprayed out at one time is limited, and multiple presses of the handle are required to spray out the cleaning agent. This operation is relatively cumbersome, and it is not convenient to increase the pressure inside the sprayer to spray out the cleaning agent, nor is it convenient to observe the pressure inside the sprayer.

[0014] By employing a combination of an injection pipe, sealing frame, sealing spring, fixed pipe, measuring cylinder, and piston, external air is connected to one end of the injection pipe. Injecting outside air into the injection pipe causes the sealing spring to bend downwards, opening the sealing frame and facilitating the injection of outside air into the storage tank. This allows for easy pressurization of the storage tank. The fixed pipe connects the measuring cylinder to the movable cover and simultaneously to the storage tank, enabling air flow from the storage tank into the measuring cylinder. Higher pressure within the storage tank pushes the piston downwards a greater distance. By observing the position of the piston, the pressure inside the storage tank can be monitored, facilitating timely inflation and pressurization. By holding the handle and rotating it to align with the measuring cylinder, the sealing plug moves to the left, connecting the delivery pipe and spray pipe. The pressure inside the storage tank forces the cleaning agent through the delivery pipe into the spray pipe, allowing for continuous atomization and spraying of the cleaning agent. This eliminates the need for repeated handle presses, making operation simple and quick. Attached Figure Description

A sealing frame 21 is fixedly connected to the inner side of the air injection pipe 2. A sealing spring 22 is fixedly installed at the bottom of the sealing frame 21. A movable cover 3 is threadedly connected to the top of the storage tank 1. A fixing frame 4 is fixedly installed on one side of the movable cover 3. One end of the fixing frame 4 extends into the inner side of the movable cover 3 and is fixedly installed with a spray pipe 5. One end of the spray pipe 5 extends out of the other side of the movable cover 3. A delivery pipe 9 is fixedly installed at the bottom of the spray pipe 5 inside the movable cover 3. One end of the delivery pipe 9 extends... Inside the storage tank 1, a sealing plug 12 is slidably installed inside the spray pipe 5. A handle 7 is movably installed inside the fixing frame 4. One end of the handle 7 extends below the fixing frame 4. A connecting rod 13 extending to the inside of the fixing frame 4 is movably installed on one side of the sealing plug 12. One end of the connecting rod 13 is movably connected to the handle 7. A measuring cylinder 6 is fixedly installed at the bottom of the fixing frame 4 on one side of the handle 7. A piston 16 is slidably installed inside the measuring cylinder 6. A measuring spring 18 is fixedly connected between the bottom of the piston 16 and the measuring cylinder 6. A fixing tube 14 is fixedly installed inside the fixing frame 4.

[0024] Atomizing nozzle 8 is fixedly installed at one end of the spray pipe 5. The atomizing nozzle 8 is connected to the spray pipe 5. One end of the delivery pipe 9 is connected to the spray pipe 5. The sealing plug 12 is located at the top of the delivery pipe 9.

[0025] The inner wall of the movable cover 3 below the fixed frame 4 is fixedly installed with an internal thread 10, and the outer periphery of the storage tank 1 is provided with a threaded groove 11 corresponding to the internal thread 10;

[0026] The top of the fixing bracket 4 inside the movable cover 3 is provided with a fixing hole 15. One end of the fixing tube 14 is connected to the fixing hole 15, and the other end of the fixing tube 14 is connected to the measuring cylinder 6.

[0027] A measuring rod 17 extending below the measuring cylinder 6 is fixedly mounted on the bottom of the piston 16, and a measuring spring 18 is located on the periphery of the measuring rod 17.

[0028] A thrust spring 19 is fixedly installed between one side of the handle 7 and the measuring cylinder 6, and the thrust spring 19 is located below the fixing frame 4;

[0029] A water injection pipe 20 is fixedly installed on the rear side of the storage tank 1, and a sealing sleeve is provided at one end of the water injection pipe 20.

[0030] The working principle of the cleaning sprayer for cleaning services based on the embodiment is as follows: by rotating the movable cover 3, the internal thread 10 and the thread groove 11 are separated, making it easy to remove the movable cover 3 from the top of the storage tank 1 for cleaning. The cleaning agent is introduced into the storage tank 1 through the water injection pipe 20. By connecting the external air inflation device to one end of the air injection pipe 2, the outside air is injected into the air injection pipe 2, and the air pressure pushes the sealing spring 22 to bend downward, which can open the sealing frame 21 and allow the outside air to flow downward through the sealing frame 21 into the storage tank 1.

[0031] It is convenient to fill the storage tank 1 with outside air through the air injection pipe 2, which facilitates the filling and pressurization of the storage tank 1. When the filling of air into the air injection pipe 2 is stopped, the elasticity of the sealing spring 22 can be used to reset and fit with the sealing frame 21, which can seal the sealing frame 21 and simultaneously seal the air injection pipe 2.

[0032] The measuring cylinder 6 and the movable cover 3 are connected by the fixed tube 14, and simultaneously connected to the storage tank 1. This allows the air in the storage tank 1 to flow through the fixed hole 15 to the inside of the fixed tube 14, and at the same time, the air flows into the measuring cylinder 6. The pressure in the air pushes the piston 16 to move downward.

[0033] By utilizing the thrust of the measuring spring 18, the piston 16 can be pushed down a greater distance when the air pressure is higher, and the piston 16 can be pushed down a shorter distance when the air pressure is lower. As the piston 16 moves up and down, it can drive the measuring rod 17 to move up and down synchronously. By observing the length of the measuring rod 17 extending below the measuring cylinder 6, the position of the piston 16 can be observed, and the pressure inside the storage tank 1 can be observed simultaneously. This facilitates the monitoring of the pressure inside the storage tank 1, so that the storage tank 1 can be pressurized in a timely manner.

[0034] By having a person hold the handle 7 and rotate it to the left, one end of the connecting rod 13 can be moved to the left, causing the other end of the connecting rod 13 to move the sealing plug 12 to the left. This opens the top of the delivery pipe 9, connecting it to the spray pipe 5. The air pressure inside the storage tank 1 can then push the cleaning agent through the delivery pipe 9 into the spray pipe 5, where it is then atomized and sprayed out through the atomizing nozzle 8. The air pressure allows for continuous atomization and spraying of the cleaning agent, eliminating the need to repeatedly press the handle 7. This makes the operation simple and quick.

[0035] By releasing the handle lever 7, the thrust of the thrust spring 19 can push the handle lever 7 back to its original position. The connecting rod 13 then simultaneously drives the sealing plug 12 back to its original position, thus sealing the delivery pipe 9.

[0036] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
