(12) As shown in FIGS. 1 to 6, an airbrush with quick switchable atomization mode a airbrush body 100 and a nozzle assembly installed at one end of the airbrush body 100 for ejecting atomized liquid. The nozzle assembly includes an air cap 200 and an adjustment mechanism, and the adjustment mechanism is used to regulate the spray pattern of the atomized liquid. The adjustment mechanism includes an switchable ring 400 movably mounted on the air cap 200, and an annular air guide chamber 410 is formed between the switchable ring 400 and the air cap 200. The adjustment mechanism further includes an air jet channel 220 and an air delivery channel 210 that supplies air to the air jet channel 220. The switchable ring 400 has a first position and a second position. When the switchable ring 400 is in the first position, the air delivery channel 210 communicates with the air jet channel 220 through the air guide chamber 410, the airflow flows through the air jet channel 220 and is ejected therefrom to shape the atomized liquid droplets, causing the atomized liquid to form a first pattern. The switchable ring 400 is provided with a partition part 420 that, when in the second position, isolates the air delivery channel 210 from the air jet channel 220, maintaining the atomized liquid in a second pattern.

(13) Referring to FIGS. 1, 2, and 3, in this embodiment, the switchable ring 400 is slidably sleeved on the air cap 200 and can reciprocate along its length to adjust the spray pattern of the atomized liquid. The first position means that the switchable ring 400 is placed at an end of the air cap 200 away from the airbrush body 100, while the second position means that the switchable ring 400 is located at an end of the air cap 200 near the airbrush body 100. Simply sliding the switchable ring 400 enables rapid switching between two atomization modes, enabling rapid switching of the atomization mode by users, effectively accommodating diverse operational requirements and multiple application scenarios.

(14) In other embodiments (not shown), the switchable ring 400 may be rotatably arranged on the air cap 200, with the annular air guide chamber 410 replaced by a single square-shaped chamber. This square chamber also has a first and second position. When the air guide chamber 410 is rotated to the first position, the air delivery channel 210 communicates with the air jet channel 220 through the air guide chamber 410, and the air jet channel 220 ejects gas to shape the atomized liquid droplets, thereby causing the atomized liquid to form a first pattern. When the air guide chamber 410 is rotated to the second position, the air delivery channel 210 and the air jet channel 220 are disconnected from the air guide chamber 410, thereby maintaining the atomized liquid ejected from the nozzle assembly in a second pattern.

(15) As shown in FIGS. 5 and 6, in this embodiment, the air cap 200 is also equipped with a conical nozzle 300 for ejecting liquid. An annular central air passage 240 exists between the nozzle 300 and the air cap 200. The central air passage 240 emits gas to atomize the liquid ejected from the nozzle 300 into a second pattern. Regardless of the position of the switchable ring 400, the central air passage 240 remains unobstructed, ensuring continuous atomization of the liquid into the second pattern. The nozzle 300 is provided with a plurality of air guide grooves 310 along its length direction. The number of air guide grooves 310 is not specifically limited, with four being the preferred configuration. These air guide grooves 310 direct the gas flow, ensuring smoother passage through the channel, thereby preventing wind energy loss and backflow noise caused by gas collisions.

(16) As shown in FIGS. 1, 3, and 5, in this embodiment, the first pattern is a fan-shaped atomized liquid, and the second pattern is a circular atomized liquid. When the switchable ring 400 is in the first position, gas passes through the air delivery channel 210, enters the air jet channel 220 via the air guide chamber 410, and is ejected from the air jet channel 220 located on the atomizing protrusion 230. This reshapes the atomized liquid into a fan shape, suitable for spraying applications requiring large-area uniform coverage. When the switchable ring 400 slides to the second position, the partition part 420 disconnects the air delivery channel 210 from the air jet channel 220, stopping gas flow through the air jet channel 220. At this point, the liquid is only atomized by the gas from the central air passage 240, forming a circular atomized liquid, which is ideal for localized precision spraying and spot spraying applications.

(17) Please refer to FIGS. 4 and 5. In this embodiment, both the air delivery channel 210 and the air jet channel 220 are formed on the air cap 200 and extend toward the air guide chamber 410. The air delivery channel 210, air jet channel 220, and atomizing protrusion 230 are symmetrically arranged. One end of the air delivery channel 210 communicates with the central air passage 240, while the other end connects to the air guide chamber 410. The air cap 200 also features an atomizing protrusion 230 at the end away from the airbrush body 100. One end of the air jet channel 220 penetrates the atomizing protrusion 230, while the other end extends toward the air guide chamber 410 and passes through the air cap 200. When the switchable ring 400 is in the first position, gas flows from the central air passage 240 through the air delivery channel 210 into the air guide chamber 410, and finally jets out from the end of the air jet channel 220 located at the atomizing protrusion 230. This shapes the atomized liquid into a fan pattern and performs secondary atomization, breaking the liquid into finer droplets and improving overall atomization. When the switchable ring 400 is in the second position, the partition part 420 disconnects the communication between the air delivery channel 210 and the air jet channel 220. The air jet channel 220 stops airflow and disengages from the air guide chamber 410, while the air delivery channel 210 remains connected to the air guide chamber 410, preventing gas leakage.

(18) Please refer to FIGS. 4 and 5. In this embodiment, both ends of the switchable ring 400 are equipped with partition parts 420, and the air guide chamber 410 is confined between these partition parts. Each partition part 420 includes a mounting slot 430 formed on the inner wall of the switchable ring 400 and a sealing ring 440 installed in the mounting slot 430. The cross-section of the sealing ring 440 is circular or D-shaped, ensuring tight contact with the outer surface of the air cap 200. The air guide chamber 410 achieves sealing through the sealing ring 440, guaranteeing airtight closure while allowing the switchable ring 400 to slide for easy control of opening and blocking of the airflow. This design offers simple operation and excellent sealing performance.

(19) As shown in FIGS. 1 and 3, in this embodiment, the air cap 200 is rotationally connected to the airbrush body 100 via a fastening nut 500. The end of the air cap 200 near the airbrush body 100 is at least partially inserted into the airbrush body 100, with a sealing ring 440 installed on the inserted portion. The air cap 200 is then rotationally fixed to the airbrush body 100 via the fastening nut 500, maintaining a certain gap between the air cap 200 and the airbrush body 100 to allow the air cap 200 to rotate relative to the airbrush body 100. The sealing ring 440 ensures an airtight fixation between the air cap 200 and the airbrush body 100, hence by rotating the air cap 200, the angle of the atomizing protrusion 230 can be switched to meet the requirements for spray width and scattering pattern in different spraying scenarios. The adjustment process does not require disassembling the airbrush; simply rotating the air cap 200 completes the angle adjustment, making the operation simple, efficient, and improving the flexibility and convenience of the airbrush. This design is suitable for complex applications such as multi-angle spraying and precise work in confined spaces.

(20) As shown in FIGS. 1 and 3, in this embodiment, the airbrush body 100 is equipped with an air intake mechanism and an atomizing material cup 140. The air intake mechanism includes an air inlet port 110 and an air inlet channel 120. The air inlet port 110 is used to connect to an external air source, such as a compressed air pipeline or portable air cylinder. One end of the air inlet channel 120 extends internally through the airbrush body 100, connecting to the air inlet port 110, while the other end penetrates into the central air passage 240 inside the airbrush body 100. The air inlet channel 120 is also equipped with an adjustment valve 130, which can be a knob, wheel, or paddle structure. The adjustment valve 130 controls the gas flow rate by altering the cross-sectional size of the air inlet channel 120, such as through the rotational offset of a valve core within the channel, enabling continuous adjustment of the gas passage area. Depending on the spraying requirements, the adjustment valve 130 can be used to regulate the pressure and flow of atomizing gas, thereby modifying the atomization effect and spray range.

(21) In summary, the above description demonstrates that the present disclosure achieves the following technical effects:

(22) By configuring the switchable ring 400 and the controllable air flow channel structure, simply sliding the switchable ring 400 to connect or disconnect the air delivery channel 210 and the air jet channel 220 through the air guide chamber 410 enables switching between two atomization patterns (fan-shaped and circular), fulfilling both large-area coverage and localized precision spraying needs with a single-step operation. Additionally, the rotatable connection between the air cap 200 and the airbrush body 100 allows users to adjust the orientation of the atomizing protrusion 230 by rotating the air cap 200 without removing the nozzle 300, adapting to various spraying angles and width requirements. This simple and quick operation further enhances the airbrush's adaptability and practicality.

(23) In the description of the present disclosure, it should be appreciated that directional terms such as front, rear, up, down, left, right, horizontal, vertical, perpendicular, horizontal and top, bottom etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present disclosure and simplifying the description. In the absence of a contrary explanation, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present disclosure; the directional terms inside, outside refer to the inside and outside relative to the contour of each component itself.

(24) For the convenience of description, spatial relative terms such as on . . . , above . . . , on the upper surface of . . . , upper etc. may be used here to describe the spatial positional relationship of a device or feature with other devices or features as shown in the drawings. It should be appreciated that spatial relative terms are intended to encompass different orientations of the device in use or operation other than the orientation described in the drawings.
