In other embodiments, the nozzle 400 and the showerhead 100 may be integrally formed, which is beneficial to enhance the structural strength and sealing performance.

Further, in some embodiments, the radial dimension of the shaft bore 130 is equal to the radial dimension of the nozzle 400 to prevent the nozzle 400 from loosening within the shaft bore 130, resulting in an uneven water mist emitted by the nozzle 400. In other embodiments, the radial dimension of the shaft hole 130 may be larger than the radial dimension of the nozzle 400, and the outer wall of the nozzle 400 and the inner wall of the shaft hole 130 may be connected by a pin key to fix the nozzle 400.

In some embodiments, the nozzle 400 is cylindrical and the shaft bore 130 is also circular. In other embodiments, nozzle 400 may have a rectangular parallelepiped or other irregular shape and shaft bore 130 may have a rectangular or other irregular shape to mate with nozzle 400.

In other embodiments, the cross-section of the first cavity 411 and the second cavity 412 perpendicular to the extending direction may also be rectangular, oval or other irregular shapes.

In other embodiments, a protection pad may be further disposed on the sidewall 432 of the gap 430 to enhance protection of the liquid inlet pipe 200, and prevent the sidewall 432 of the gap 430 from directly abutting against the liquid inlet pipe 200 to press the liquid inlet pipe 200.

In some embodiments, the second branch pipe 220 is arranged coaxially with the inlet chamber 410 to make the generated water mist more uniform. In other embodiments, the second branch pipe 220 and the liquid inlet chamber 410 may be arranged non-coaxially as long as the water mist can be generated.

Further, in some embodiments, the outer wall of the inlet conduit 300 is threaded with the inlet chamber 420 and the inner wall of the inlet passage 120 and is sealed by a sealing ring to prevent air leakage during the air supply process. In other embodiments, the outer wall of the inlet pipe 300, the inlet chamber 420 and the inner wall of the inlet passage 120 may be further provided with a sealing gasket or sealant to enhance the sealing effect.

The external gas is compressed air.

In the atomizing device, the liquid inlet cavity 410 is stepped, and after the gas enters the second cavity 412 from the gas inlet cavity 420, the gas surrounds the outer wall of the liquid inlet pipeline 200 in the second cavity 412, so that the gas and the liquid are mixed at the outlet 413 of the liquid inlet pipeline 200 of the nozzle 400 to form water mist for spraying, and the liquid is prevented from being frozen before being sprayed out again due to too low external temperature and cannot be sprayed out from the nozzle 400; the second branch pipe 220 is coaxially arranged with the liquid inlet cavity 410 so as to generate more uniform water mist; the outer wall of the air inlet pipeline 300 is connected and sealed with the air inlet cavity 420 and the inner wall of the air inlet channel 120 through threads, air leakage in the air supply process is prevented, the structural design is simple, and the atomization effect is good.
