[0029] This application discloses a jetting machine, including a housing 100, with a mounting cavity 110 inside the housing 100; an air tank 200 is disposed inside the mounting cavity 110, and at least a portion of the air tank 200 is exposed outside the housing 100; an air pump 300 is also disposed inside the housing 100, and the air pump 300 is connected to the air tank 200 to supply air to it; wherein, the portion of the air tank 200 exposed outside the housing 100 has an air outlet, and the air outlet is connected to and connected to a nozzle connection structure 400, which is used to connect to a designated nozzle 800.

[0030] In this embodiment, the spraying machine has a housing 100, within which a mounting cavity 110 is provided. The mounting cavity 110 is used to house an air tank 200. A portion of the air tank 200 is placed within the mounting cavity 110 for protection, while another portion of the air tank 200 is exposed outside the housing 100. An air outlet is formed on this exposed portion, and the air outlet is connected to and communicates with a nozzle connection structure 400. A designated nozzle 800 is connected through the nozzle connection structure 400. The nozzle 800 includes, but is not limited to, a paper spraying pipe, a water spraying pipe, a powder spraying pipe, etc., and can be configured according to... Different usage scenarios can be selected; an air pump 300 is installed inside the housing 100 and connected to the air tank 200 to supply air, eliminating the need for an external air cylinder for air supply, resulting in a more compact structure; in use, first install the desired nozzle 800 (containing the desired type of consumables) on the nozzle connection structure 400, and then inflate the air tank 200 with air pump 300 to increase the air pressure inside the air tank 200. After reaching the preset air pressure, the spray valve of the air tank can be opened through the control terminal to release the gas from the outlet, thereby spraying out the consumables inside the nozzle 800.

[0031] Furthermore, a jet valve assembly 210 is provided at the bottom of the gas tank 200 for starting and stopping the jetting action. The gas pressure inside the gas tank 200 can be continuously increased by closing the jet valve assembly 210, and the gas pressure inside the gas tank 200 can be released by opening the jet valve assembly 210. At the same time, the main body of the jet valve assembly 210 is located at the bottom of the gas tank 200 rather than the top, making the overall structure more compact and aesthetically pleasing. The jet valve assembly 210 includes a jet valve 211 and a matching discharge pipe 212.

[0032] In an optional or preferred embodiment, the nozzle connection structure 400 can be, for example, a pipe connection clamp, to effectively fix the nozzle 800 while also allowing for quick disassembly and replacement.

[0033] In an optional or preferred embodiment, the gas tank 200 is rotatably connected to the housing 100, and the housing 100 is provided with a locking structure 130 for locking the position of the gas tank 200.

[0034] In this embodiment, the gas tank 200 is rotatably connected to the housing 100, so that when the gas tank 200 rotates, it can drive the nozzle 800 to rotate to a preset angle, thereby spraying the consumables to the designated position along a preset route; at the same time, a locking structure 130 is provided, so that after the nozzle 800 rotates to the preset angle, the position of the gas tank 200 can be fixed by the locking structure 130, that is, the tilt angle of the nozzle 800 is fixed.

[0035] In an optional or preferred embodiment, the gas cylinder 200 is configured to be cylindrical, with its outer circular surface protruding outside the housing 100; the locking structure 130 includes at least one clamping ring 131 and a fastening switch 132, all clamping rings 131 being able to contact the portion of the gas cylinder 200 protruding outside the housing 100, and the fastening switch 132 being used to clamp the gas cylinder 200 with the clamping rings 131 or to release the clamping of the gas cylinder 200.

[0036] In this embodiment, the gas tank 200 is cylindrical, which provides good air pressure resistance and facilitates rotation of the gas tank 200 to adjust the rotation angle of the nozzle 800. The locking structure 130 can be configured in various ways, such as with damped friction contact between the gas tank 200 and the housing 100, allowing it to self-lock after rotating at any angle; or it can be fixed with bolts. To match the overall structure of this jetting machine, a preferred design is shown below: the locking structure 130 includes at least one clamping ring 131 and a fastening switch 132. All clamping rings 131... The accessible portion of the gas cylinder 200 protrudes from the surface outside the housing 100. The fastening switch 132 is used to tighten or loosen the clamping ring 131 around the gas cylinder 200. This eliminates the need to modify the gas cylinder 200 itself, and the clamping ring 131 has a large contact area with the cylindrical gas cylinder 200, achieving a good fixing effect. Optionally, the fastening switch 132 can be a hand-tightening screw, which tightens or loosens the clamping ring 131 by turning it. Furthermore, two clamping rings 131 are provided, symmetrically distributed at both ends of the gas cylinder 200, thereby ensuring good stability after the gas cylinder 200 is fixed.

[0037] In an optional or preferred embodiment, the gas tank 200 is connected to the internal pressure control system 500, and the housing 100 is provided with a control panel 120 connected to the internal pressure control system 500; the internal pressure control system 500 can control the pressure value inside the gas tank 200 according to the actual use, while the control panel 120 can be easily operated manually.

[0038] In an optional or preferred embodiment, the tank pressure control system 500 includes a safety valve assembly 510. The safety valve assembly 510 is connected to the side of the gas tank 200 facing the bottom of the housing 100, and the mounting cavity 110 is provided with a rotation space corresponding to the safety valve assembly 510. With the safety valve assembly 510, when the gas pressure in the gas tank 200 exceeds a preset value, it can automatically release pressure to prevent accidents. At the same time, the connection of the safety valve assembly 510 to the side of the gas tank 200 facing the bottom of the housing 100 and the rotation space provided by the mounting cavity 110 corresponding to the safety valve assembly 510 facilitate the concealment and protection of the safety valve assembly 510, and avoid interference with the safety valve assembly 510 when the gas tank 200 drives the nozzle 800 to rotate.

[0039] In an optional or preferred embodiment, the internal pressure control system 500 further includes an external pressure detection component 520 and an exhaust valve component 530; the pressure detection component 520 monitors the pressure changes inside the gas tank 200 in real time; and the exhaust valve component 530 controls the gas tank 200 to exhaust gas when needed, for example, to discharge residual gas after each use of consumables.

[0040] Optionally, the pressure detection component 520 includes a pressure tube 521 and a pressure gauge 522 connected to the pressure tube 521. The pressure tube 521 is connected to the gas tank 200 and detects the pressure inside the gas tank 200 externally. This avoids making the mounting components on the gas tank 200 too dense and prevents interference of the sensing lines on the pressure detection component 520 when the gas tank 200 rotates. Preferably, the pressure detection component 520 also includes a separate pressure sensor 523 for real-time detection of the pressure inside the gas tank 200 and feedback to the control terminal.

[0041] Furthermore, the nozzle connection structure 400 can be connected to a water spray pipe; the exhaust valve assembly 530 is connected to an exhaust pipe 531 and the outlet of the exhaust pipe 531 is located outside the housing 100; since a water spray pipe can be connected to the nozzle connection structure 400, if the liquid in the water spray pipe seeps into the gas tank 200, the outlet may cause a short circuit or affect the life of electrical components inside the housing 100 if it is inside the housing 100 during exhaust. Therefore, the liquid can be discharged smoothly through the exhaust pipe 531 outside the housing 100, reducing the risk when using the water spray pipe; preferably, the outer end of the exhaust pipe 531 is connected to a muffler 532 to reduce the noise generated by the exhaust.

[0042] In an optional or preferred embodiment, the air pump 300 and the air tank 200 are connected by an air supply pipe 310.

[0043] In an optional or preferred embodiment, the pressure pipe 521, the air supply pipe 310, and the exhaust valve assembly 530 are connected via the distributor 900, and the air tank 200 is also connected. It is understood that the distributor 900 can also connect to pipes that need to be connected as needed, depending on the actual situation.

[0044] In an optional or preferred embodiment, an angle limiting structure 140 is provided on the housing 100 to limit the rotation angle of the gas tank 200, so as to prevent the gas tank 200 from rotating too much with the nozzle 800 and causing a phenomenon such as collision with the housing 100. At the same time, it can also provide a positioning effect for the nozzle 800. Optionally, the angle limiting structure 140 limits the rotation angle of the nozzle 800 to a range of -30° to 30°. Preferably, the rotation range is set to -45° to 45° to meet the tilt angle requirements of the nozzle 800 in most situations.

[0045] In an optional or preferred embodiment, the limiting structure 140 includes a first limiting member 141 and a second limiting member 142, which are adapted to abut against each other in the rotation direction of the gas tank 200, and the gas tank 200 connects one of them; the other of the two is disposed on the housing 100.

[0046] In this embodiment, the first limiting member 141 and the second limiting member 142 are configured such that after the gas tank 200 rotates by a certain angle, the first limiting member 141 and the second limiting member 142 will abut against each other, thereby preventing the gas tank 200 from continuing to rotate and achieving a limiting effect. Optionally, a buffer structure is provided between the first limiting member 141 and the second limiting member 142, such as an elastic layer or a soft layer with shock absorption and buffering effect on the outer side of at least one of them. For ease of understanding, as... Figure 2-4 As shown, a first limiting member 141 is connected to one side of the gas tank 200. The first limiting member 141 is a bent structure, and its abutting end extends upward beyond the housing 100. A second limiting member 142 is provided on the hoop 131. The second limiting member 142 can be a buffer column. After the gas tank 200 rotates a certain angle, the abutting end of the bent structure is blocked by the buffer column, so that the nozzle 800 cannot continue to rotate with the gas tank 200.

[0047] In an optional or preferred embodiment, the bottom of the housing 100 is provided with a caster wheel assembly to facilitate the free movement of this application.

[0048] In an optional or preferred embodiment, one or more control switches 700 are provided on the top of the housing 100. The control switches 700 can control, for example, the opening and closing of the exhaust valve assembly 530 (i.e., the exhaust switch, which can control the opening and closing of the exhaust and the exhaust speed), the opening and closing of the safety valve assembly 510 (i.e., the safety valve switch), the opening and closing of the outlet valve (i.e., the injection valve switch), the opening and closing of the air pump 300 (i.e., the air pump switch), etc. Different control switches 700 can be set according to the actual situation.
