[0066] The technical solution of the present application is further explained below in conjunction with the accompanying drawings and through specific implementation methods.

[0067] like Figures 1 to 5 As shown, this embodiment provides a spray fan, which includes a fan assembly 100 and a nozzle 200. The fan assembly 100 is arranged on a base 300. The fan assembly 100 includes fan blades and a motor, and the motor is used to drive the fan blades to rotate. The spray fan sucks in liquid through a water inlet and a water inlet pipe and sprays it out. The liquid can be a static liquid or a dynamic liquid. The nozzle 200 is configured to spray liquid. The nozzle 200 includes a nozzle 210 and an impact portion 221, and the liquid leaves the nozzle 200 through the nozzle 210. At least part of the impact portion 221 is arranged on the spray path after the liquid leaves the nozzle 200. The nozzle 200 includes a nozzle body 201, and the nozzle 210 is arranged on the nozzle body 201. The nozzle body 201 has a cavity 212 inside for liquid flow. The spray fan is driven by direct current.

[0068] The spray fan is provided with an impact part 221, which breaks up and disturbs the flow of the liquid, so that the spray fan sprays out a finer mist. Since the liquid is broken up by impact, rather than being quickly sprayed out through a very small orifice 2111, the nozzle 210 in the present application can be designed with a larger orifice 2111, thereby allowing more viscous or impure fluids to be sprayed into a mist.

[0069] The impact part 221 is configured to break up the liquid. With the above configuration, the liquid can be broken down after passing through the impact part 221, so that the diameter of the droplets formed by the liquid is smaller. In this embodiment, the striker 220 is U-shaped, one end of the striker 220 is fixed on the nozzle 210, and the impact part 221 is located at the other end of the striker 220.

[0070] The spray head 200 extends substantially along the first direction a, and at least part of the impact portion 221 overlaps with the projection of the nozzle 210 in the first direction a. This arrangement enables the liquid to flow along the first direction a, so that the liquid must pass through the impact portion 221 and be broken by the impact during the flow process.

[0071] Regarding the power required for the flow of liquid, in this embodiment, the spray fan includes a pump disposed upstream of the nozzle 200, and the pressure generated by the pump is greater than or equal to 50 psi and less than or equal to 1000 psi. The above arrangement enables the liquid to have a certain speed after flowing out of the nozzle 200, so that it is decomposed during the impact process of the impact part 221. Among them, the degree of liquid decomposition is positively correlated with the pressure of the pump. In other words, the greater the pressure of the pump, the faster the liquid flow rate, and thus the greater the impact force generated when contacting the impact part 221, and thus the better the decomposition effect and the smaller the droplets.

[0072] The outlet of the spray hole 211 of the nozzle 210 is defined as an orifice 2111 , and the diameter of the orifice 2111 is greater than or equal to 0.1 mm and less than or equal to 0.6 mm.

[0073] In some embodiments, the diameter of the orifice 2111 is greater than or equal to 0.1 mm and less than or equal to 0.3 mm. In some embodiments, the diameter of the orifice 2111 is greater than or equal to 0.1 mm and less than or equal to 0.2 mm.

[0074] Since the liquid flow rate in the injection hole 211 is relatively high, in order to prevent the nozzle 210 from being easily worn by the high-speed flowing liquid and causing the aperture to become larger, in this embodiment, the nozzle 210 is made of ruby, and the injection hole 211 passes through the nozzle 210. Ruby has a relatively high hardness and is therefore more wear-resistant, which is conducive to extending the service life while ensuring the atomization effect.

[0075] In this embodiment, the impact part 221 includes a cone, and the cone has a tip 2211, and the tip 2211 is used to break up the liquid. Specifically, the diameter of the cone gradually decreases along the second direction b. The axis of the cone coincides with the axis L of the nozzle 200. The setting of the tip 2211 allows the liquid to be evenly dispersed around the axis of the cone when decomposing, so that the atomization effect of the liquid is also more uniform. The second direction b is opposite to the first direction a.

[0076] like Figure 6 As shown, this embodiment also provides a spray fan, which includes a fan assembly 100 and a spray head 200. The fan assembly 100 includes a fan blade and a motor, and the motor is used to drive the fan blade to rotate. The spray head 200 is configured to spray liquid. The spray head 200 includes a spiral portion 230, and the spiral portion 230 shears the liquid when guiding the liquid to flow.

[0077] The spray fan is provided with a spiral portion 230. The spiral portion 230 is provided so that liquid impacts the protruding spiral shape, causing the liquid to be sheared and split into droplets, thereby allowing the spray fan to spray out finer water mist.

[0078] Regarding the structure of the spiral portion 230, in this embodiment, the spiral portion 230 converges toward the axis L of the nozzle 200 along the liquid flow direction, and the spiral portion 230 has a plurality of layers of spiral structures. The spiral portion 230 has a tapered flow channel with a gradually decreasing diameter along the axis L, one end of the flow channel is connected to the cavity 212 of the nozzle 200, and the liquid is sheared and split by the plurality of spiral portions 230 during the flow of the flow channel.

[0079] The spiral portion 230 forms a plurality of impact surfaces, each of which has a different angle relative to the axis L. This arrangement allows the liquid sheared by the spiral portion 230 to impact the impact surface, thereby dispersing in a direction away from the axis L. Since the angles of the impact surfaces relative to the axis L are different, the range of liquid dispersion is larger. In some embodiments, three impact surfaces are provided, and along the first direction a, the angles between the three impact surfaces and the axis L gradually decrease. In some embodiments, four impact surfaces are provided, and along the first direction a, the angles between the four impact surfaces and the axis L gradually decrease. In some embodiments, six impact surfaces are provided, and along the first direction a, the angles between the six impact surfaces and the axis L gradually decrease. The more impact surfaces there are, the more layers the liquid can be sheared, thereby forming a more uniform spraying surface. The fewer impact surfaces there are, the lower the speed at which the liquid needs to leave the nozzle 200, and the more energy-saving it is. In this embodiment, along the first direction a, multiple impact surfaces are smoothly connected end to end. The impact surface is inclined toward the first direction a along the direction away from the axis L, that is, the angle between the flow direction of the decomposed liquid and the first direction a is an acute angle.

[0080] like Figure 7 and Figure 8As shown, this embodiment also provides a spray fan, which includes a fan assembly 100 and a spray head 200. The fan assembly 100 includes a fan blade and a motor, and the motor is used to drive the fan blade to rotate. The spray head 200 is configured to spray liquid, and the spray head 200 includes a cavity 212 for liquid flow. The cavity 212 is provided with a vortex portion, and the vortex portion is configured to cause the liquid to generate a vortex.

[0081] The spray fan is provided with a vortex portion, and the liquid generates eddy current motion after passing through the vortex portion, and the generated turbulence breaks the liquid into droplets. Afterwards, when the broken droplets leave the orifice 2111, a complete cone pattern is formed, so that the spray fan sprays a finer mist.

[0082] Regarding the structure of the vortex portion, in the present embodiment, the vortex portion includes a stopper 240, the stopper 240 collides with the liquid to cause the liquid to generate a vortex, and the stopper 240 is arranged in the cavity 212. The setting structure of the stopper 240 is simple and easy to manufacture and install. Specifically, the stopper includes at least two vortex rods, and the two vortex rods intersect with each other. In some embodiments, the stopper includes three vortex rods, and the three vortex rods intersect with each other. In some embodiments, the stopper includes four vortex rods, and the four vortex rods intersect with each other.

[0083] In some embodiments, the vortex portion is formed with a guide portion, which guides the liquid to generate a vortex, and the guide portion is disposed in the cavity 212. The guide portion is a flow channel structure, and the liquid forms a complete cone pattern when it leaves the orifice 2111 under the guidance of the guide portion.

[0084] The nozzle 200 extends substantially along the axis L, and the rotation axis of the vortex is substantially parallel to the axis L. The above-mentioned direction arrangement is conducive to the atomized liquid flowing out of the nozzle 200 smoothly.

[0085] like Figures 9 to 11 As shown, this embodiment also provides a spray fan, which includes a fan assembly 100 and a nozzle 200. The fan assembly 100 includes a fan blade and a motor, and the motor is used to drive the fan blade to rotate; the nozzle 200 is configured to spray liquid, and the nozzle 200 includes a mixing chamber 260 for liquid flow. The spray fan also includes a pressurizing system, and the pressurizing system is configured to pressurize the gas. The pressurizing system includes a gas outlet 250, and the gas outlet 250 is connected to the mixing chamber 260.

[0086] The spray fan is provided with a pressurizing system, and the high-pressure gas generated by the pressurizing system impacts the liquid in the mixing chamber 260, causing it to split into fine sprays, so that the spray fan sprays a finer mist. The pressurizing system includes a pressurizing pump and a pipeline, and the pressurizing pump delivers gas to the gas outlet 250 through the pipeline. The provision of the pressurizing pump makes the gas supply more convenient and is conducive to the adjustment of the pressure, thereby achieving different degrees of adjustment of the atomization. The pressurizing pump includes a plunger air pump, a screw air pump, etc. The specific structure and pressure adjustment method of the pressurizing pump are well known to those skilled in the art, so they are not repeated here.

[0087] The nozzle 200 extends substantially along the axis L, and the opening direction of the mixing chamber 260 is substantially parallel to the axis L. The nozzle 200 includes a nozzle 210, the nozzle 210 is made of ruby, and the mixing chamber 260 runs through the nozzle 210. The nozzle 200 extends substantially along the axis L, and the opening direction of the mixing chamber 260 is substantially perpendicular to the axis L. The nozzle 200 includes a nozzle 210, the nozzle 210 is made of ruby, and the mixing chamber 260 runs through the nozzle 210.

[0088] In some embodiments, the nozzle 200 extends substantially along the axis L, and the opening direction of the mixing chamber 260 is arranged at an acute angle to the axis L. That is, the flow direction of the liquid is at an acute angle to the first direction a. The nozzle 200 includes a nozzle 210, which is made of ruby, and the mixing chamber 260 passes through the nozzle 210.

[0089] The nozzle 200 extends substantially along the axis L, and a plurality of gas outlets 250 are provided, and the plurality of gas outlets 250 are arranged circumferentially around the axis L. This arrangement can evenly impact the liquid, thereby increasing the liquid flow rate and evenly dispersing and decomposing the liquid to form a mist.

[0090] The liquid flows out from the internal channel 261 of the nozzle 200 through the channel outlet 262 and then enters the mixing chamber 260, wherein the inner diameter of the channel 261 is much larger than the inner diameter of the channel outlet 262. Specifically, the ratio of the inner diameter of the channel 261 to the inner diameter of the channel outlet 262 is greater than five. This arrangement can prevent the liquid from flowing back into the channel 261 under the action of air pressure.

[0091] Obviously, the above embodiments of the present application are only examples for clearly illustrating the present application, and are not intended to limit the implementation methods of the present application. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here.
