Description
Technical Field
[0001] This utility model relates to the field of spray device technology, and specifically to an adjustable spray device. Background Technology
[0002] A spray device is a device that uses a high-pressure pump to pressurize a liquid, which is then sprayed out through a narrow nozzle. During this process, the liquid and high-pressure gas can be mixed, and the mixture is sprayed out to create an atomization effect.
[0003] For example, Chinese patent CN220654555U discloses a spraying device that is equipped with multiple nozzles. During use, the connection state between the delivery pipe and different nozzles can be changed to achieve various spraying effects.
[0004] However, the device cannot adjust the sprayed medium; for example, when cleaning, it is necessary to spray a gas-liquid mixture to dissolve the dirt, and then it is necessary to clean it with high-pressure airflow; the device and existing equipment are difficult to spray different media through simple switching operations.
[0005] Based on this, the present invention designs an adjustable spray device to solve the above problems. Utility Model Content
[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an adjustable spraying device.

[0010] The adjustable spray gun includes a housing, a gas channel, a liquid channel, and an adjustment module. The gas channel and the liquid channel are installed inside the housing, and a nozzle for spraying is installed at the end of the liquid channel. The nozzle is connected to the gas channel and the liquid channel respectively. An adjustment module for controlling the opening and closing of the liquid channel is installed on the housing.
[0011] The upper part of the water tank is connected to the air pump via a pressurization hose; the bottom of the water tank is connected to the gas channel via a delivery hose.
[0012] Furthermore, the water tank opening is threaded with a tank cover, and a sealing gasket is placed between the tank cover and the water tank; a pressure gauge for detecting the pressure inside the water tank is fixedly installed on the tank cover; and a pressure relief valve for releasing pressure inside the water tank is fixedly installed on the tank cover.
[0013] Furthermore, the outer casing includes a gun body and a spray bar, with the gun body fixedly connected to one end of the spray bar and the other end of the spray bar inserted into a nozzle.

An air inlet channel is provided inside the gun body, and an outer tube is fixedly installed inside the spray bar. The air pump is connected to the nozzle through the hose, the air inlet channel, and the outer tube.
[0015] Furthermore, the liquid channel includes a second flexible hose, a connecting seat, and an inner tube. One end of the second flexible hose is fixedly connected to the bottom of the water tank, and the other end of the second flexible hose is fixedly connected to the gun body. The gun body has an inlet channel, a cavity, and an outlet channel. The connecting seat is fixedly installed in the gun body and is fixedly connected to one end of the inner tube. The male connector of the quick connector is fixedly connected to the other end of the inner tube, and the female connector of the quick connector is fixedly connected to the nozzle.

One end of the hose 721 is fixedly connected to the air pump 4, and the other end of the hose 721 is fixedly connected to the gun body 711. An air inlet passage 722 is provided inside the gun body 711, and the outer tube 723 is fixedly installed inside the spray bar 712. The air pump 4 is connected to the nozzle 8 through the hose 721, the air inlet passage 722, and the outer tube 723.
[0043] The liquid channel 73 includes a second hose 731, a connecting seat 735, and an inner tube 736. One end of the second hose 731 is fixedly connected to the bottom of the water tank 5, and the other end of the second hose 731 is fixedly connected to the gun body 711. The gun body 711 has an inlet channel 732, a cavity 733, and an outlet channel 734. The connecting seat 735 is fixedly installed inside the gun body 711 and is fixedly connected to one end of the inner tube 736. The male connector of the quick connector is fixedly connected to the other end of the inner tube 736, and the female connector of the quick connector is fixedly connected to the nozzle 8. The water tank 5 is connected to the nozzle 8 through the second hose 731, the inlet channel 732, the cavity 733, the outlet channel 734, the connecting seat 735, the inner tube 736, and the quick connector.
[0044] The adjustment module 74 includes an unlocking module and a blocking module, which are mounted on the gun body 711 and connected together.
[0045] The unlocking module includes a trigger 741, a lever 742, and a limiting sleeve 743. The middle part of the trigger 741 is rotatably mounted on the gun body 711. One end of the trigger 741 is rotatably connected to the lever 742. The limiting sleeve 743 is fixedly mounted on the gun body 711. The other end of the lever 742 passes through the limiting sleeve 743 and is located in the cavity 733.
[0046] The sealing module includes a spring 744, a piston 745, and a sealing ring 746. The sealing ring 746 is snapped into the end of the cavity 733 away from the limiting sleeve 743. The piston 745 for blocking the end of the cavity 733 away from the limiting sleeve 743 is fixedly installed on the end of the pull rod 742 located in the cavity 733. The spring 744 is sleeved on the outside of the pull rod 742 located in the cavity 733. One end of the spring 744 is fixedly connected to the cavity 733, and the other end of the spring 744 is fixedly connected to the piston 745.
[0047] In this embodiment, when the adjustable spray gun 7 is working normally, under normal conditions, the pull rod 742 and piston 745 are inserted into the middle of the sealing ring 746 under the restoring force of the spring 744; thereby disconnecting the connection between the cavity 733 and the outflow channel 734; at this time, the air pump 4 is turned on, and the air pump 4 causes the gas to enter the nozzle 8 through the hose 721, the air inlet channel 722 and the outer tube 723 and then be sprayed out directly; forming a jet effect;
[0048] Pressing the trigger 741 rotates the lever 742, which moves the lever 742. Under the limiting action of the limiting sleeve 743, the lever 742 moves in a straight line outward from the gun body 711. The lever 742 drives the piston 745 to move, and the spring 744 is compressed. At this time, the piston 745 disengages from the sealing ring 746. The air pump 4 causes gas to enter the nozzle 8 through the first hose 721, the air inlet channel 722, and the outer tube 723. At the same time, the air pump 4 pressurizes the water tank 5 through the pressurizing hose 61. Then, the liquid in the water tank 5 flows through the delivery hose 62, the second hose 731, the liquid inlet channel 732, the cavity 733, and the outlet channel 734 to the connecting seat 735 and the inner tube 736. Then, it enters the nozzle 8 through the quick connector along the inner tube 736. The gas flowing out of the outer tube 723 and the liquid flowing out of the inner tube 736 come into contact and mix in the nozzle 8 and are then sprayed out through the nozzle 8 to form a spray effect.
[0049] The support clip 21 is engaged with the spray bar 712.
