Description

The atomizing nozzle can effectively increase the contact area between the atomized medium and the surrounding medium, and can be widely applied in the fields of dust removal, combustion, medical treatment, humidification, beauty, etc.

[0003] The atomizing nozzle used in the related art utilizes a certain pressure gas to form a high-pressure gas flow to scatter the atomized medium sprayed at low pressure to form atomized particles. The atomizing nozzle selects a small-diameter liquid outlet to reduce the liquid output of the atomized medium, so that the high-pressure gas can more easily scatter the atomized medium to form atomized particles with small particle size. However, for the atomization of liquid with high viscosity, the atomized medium is difficult to be scattered due to its large surface tension, and problems such as large atomized particles, incomplete atomization and discontinuity are prone to occur, which is difficult to meet the user's use requirements.

[0046] The embodiment of the present application provides an atomizing nozzle 11.

[0047] Specifically, the atomizing nozzle 11 is used to atomize the atomizing liquid to generate aerosol.

[0048] Please refer to Figures 2 to 8 , the atomizing nozzle 11 comprises a shell 111 and a core 112.

[0049] The shell 111 has a containing space 111a, an atomizing channel 111b, and a communication port 111c, the communication port 111c communicates the atomizing channel 111b and the containing space 111a, and one end of the atomizing channel 111b away from the communication port 111c communicates with the external environment. The core 112 is arranged in the containing space 111a, and the core 112 has a liquid outlet 112a and a liquid channel 112b, the liquid channel 112b is used to pass the atomizing liquid, one end of the liquid outlet 112a communicates with the liquid channel 112b, and the other end communicates with the communication port 111c.

[0050] The atomizing liquid refers to the liquid which is converted into fine droplets or aerosol form in the atomizing process. The atomizing liquid can be a medicine liquid or tobacco tar, etc., which is not limited here. Specifically, the atomizing liquid in the liquid channel 112b flows through the liquid outlet 112a, the communication port 111c, and the atomizing channel 111b, and the atomizing liquid is atomized in the atomizing channel 111b, and the aerosol or fine droplets generated by the atomizing liquid are directly discharged to the external environment for the user to use.

[0051] It can be understood that the atomizing channel 111b can be exposed on the outer surface of the atomizing nozzle 11, so that the aerosol or fine droplets generated after atomization can be directly used by the user.

[0052] The atomizing nozzle 11 has a gas channel 11a and a gas outlet 11b, the gas outlet 11b is communicated with the gas channel 11a and the atomizing channel 111b, and the gas outlet 11b is used for spraying gas to atomize the atomized liquid sprayed from the liquid outlet 111a.

[0053] It can be understood that the spraying here refers to that the gas sprayed from the gas outlet 11b is a gas with a certain pressure (greater than or much greater than atmospheric pressure) and flow rate, and the atomized liquid sprayed from the liquid outlet 111a is also a liquid with a certain pressure (greater than or much greater than atmospheric pressure) and flow rate, and when the two collide, a strong shear force can be generated to break the atomized liquid into fine droplets.

[0054] It can be understood that the forming mode of the gas channel 11a is not limited, and exemplarily, the core body 112 and the shell 111 can jointly define the gas channel 11a, here, the outer surface of the core body 112 and the inner surface of the accommodation space 111a can jointly define the gas channel 11a, or the core body 112 itself can define part of the gas channel 11a, and the outer surface of the core body 112 and the inner surface of the accommodation space 111a can define another part of the gas channel 11a; of course, in other examples, it can also be defined by other structures.

[0055] The forming mode of the gas outlet 11b is not limited, and exemplarily, in some embodiments, the outer surface of the core body 112 close to the liquid outlet 112a side and the space between the inner surface of the communication port 111c and the inner surface of the accommodation space 111a form the gas outlet 11b.

[0056] It can be understood that the gas outlet 11b is a structure with a certain extension size, that is, it can generally form a channel for high-pressure high-speed gas to be sprayed out. The high-pressure high-speed gas in the gas channel 11a flows to the atomizing channel 111b through the gas outlet 11b to impact and cut the atomized liquid sprayed from the liquid outlet 111a, and tear the atomized liquid.

[0057] Among them, the flow passage cross-sectional area of the gas outlet 11b decreases along the gas flow direction.

[0058] It should be noted that the decrease of the flow passage cross-sectional area of the gas outlet 11b refers to the overall decrease of the flow passage cross-sectional area, and the decrease here can be continuous or stepwise. The continuous decrease here can be linear, exponential or logarithmic.

[0059] Exemplarily, the flow passage cross-sectional area of the gas outlet 11b continuously decreases along the gas flow direction, so that the flow stability of the high-pressure high-speed gas in the gas outlet 11b can be increased, thereby increasing the atomizing effect.

[0060] It should be noted that the flow passage cross-sectional area refers to the flow area for the gas flow.

[0061] It can be understood that the gas can be pressurized and accelerated by mechanical means before entering the gas channel 11a of the atomizing nozzle 11, for example, by a gas pump (also known as an air compressor or compressor), so as to obtain high-pressure and high-speed gas, which is sprayed out through the gas channel 11a and the gas outlet 11b. Thus, when passing through the gas outlet 11b with a continuously decreasing flow area, the pressure and speed of the gas can be further increased.

[0062] That is, the flow area of the gas outlet 11b decreases in the direction close to the atomizing channel 111b. When the flow area decreases, the flow rate and pressure of the high-pressure and high-speed gas in the gas outlet 11b increase, thereby generating stronger shear force.

[0063] Specifically, the high-pressure and high-speed gas flow meets the atomizing liquid at the inlet of the atomizing channel 111b, generating strong shear force, which helps to split the atomizing liquid into small particles and tear the atomizing liquid into liquid film, liquid wire, liquid strip and small droplets, thereby realizing atomization. Meanwhile, the increase of the flow rate and pressure of the gas flow also helps to drive the atomizing liquid at the liquid outlet 112a to pass through the liquid outlet 112a faster, thereby reducing the risk of blockage.

[0064] The atomizing nozzle 11 provided by the embodiment of the present application has a decreasing flow area of the gas outlet 11b along the flow direction of the gas flow, which can enable the gas to be sprayed out at a higher speed and a higher pressure, the high-pressure and high-speed gas can generate stronger shear force to effectively split the atomizing liquid to form atomized particles with a small enough particle size, thereby reducing the probability of incomplete atomization of the high-viscosity medium, and the high-pressure and high-speed gas flow can also facilitate the atomizing liquid to flow out through the liquid outlet 112a quickly, thereby reducing the probability of blockage of the liquid outlet 112a by the high-viscosity atomizing liquid and increasing the user experience.

[0065] For example, the gas pressure of the high-pressure and high-speed gas entering the gas channel 11a can be adjusted by adjusting the parameters of the gas pump. Of course, the gas pressure of the high-pressure and high-speed gas sprayed out from the gas outlet 11b can also be adjusted by adjusting the decreasing manner of the flow area of the gas outlet 11b and the size of the flow area of the gas outlet 11b, which is not limited herein.

[0066] Of course, the flow area of the liquid channel 112b and the liquid outlet 112a can also be designed to adjust the liquid inlet amount of the liquid channel 112b, so as to facilitate atomization with appropriate liquid inlet amount and appropriate gas pressure.

[0067] The number of the gas outlets 11b is not limited and can be one or multiple.

[0068] For example, in some embodiments, please refer to Figure 5 and Figure 6The number of the gas outlets 11b is multiple, and the multiple gas outlets 11b are arranged in a circumferential direction and surround the liquid outlet 112a in a planar projection perpendicular to the axial direction of the atomizing nozzle 11.

[0069] It can be understood that the multiple gas outlets 11b arranged in the circumferential direction are independent of each other and do not affect each other.

[0070] In this embodiment, the multiple gas outlets 11b can simultaneously spray high-pressure and high-speed gas, so that the gas flow forms multiple high-speed gas flow points around the liquid outlet 112a, and more uniformly contacts the atomized liquid. The gas outlets 11b arranged around the liquid outlet 112a can make the gas flow effectively mixed with the atomized liquid in all directions, thereby improving the atomization effect.

[0071] At the same time, the high-speed gas flow generated by the multiple gas outlets 11b can apply shear force to the atomized liquid in multiple directions, so that the atomized liquid is cut multiple times to be broken into small particles, thereby increasing the atomization completeness and reducing the atomization particle size. In addition, the multiple gas outlets 11b can also provide multiple gas flow paths, so that even if one gas outlet 11b is blocked, the other gas outlets 11b can still work. At the same time, it can also help the atomized liquid to flow out of the liquid outlet 112a.

[0072] In some embodiments, referring to Figure 6 The number of the gas outlets 11b is three, and the included angle β between the center line of any two adjacent gas outlets 11b and the center line of the liquid outlet 112a is 120°.

[0073] In this embodiment, the number of the gas outlets 11b is three, and each gas outlet 11b is uniformly arranged, which facilitates to increase the uniformity of the atomization effect. At the same time, the distance between the three gas outlets 11b can be relatively appropriate, so that the atomizing nozzle 11 has three gas flow paths, thereby enhancing the cutting effect on the atomized liquid. In addition, the three gas outlets 11b do not affect each other, and the overall structure of the atomizing nozzle 11 is relatively stable, thereby increasing the atomization reliability.

[0074] In other embodiments, referring to Figure 5 The number of the gas outlets 11b is four, and the included angle between the center line of any two adjacent gas outlets 11b and the center line of the liquid outlet 112a is 90°.

[0075] In some embodiments, referring to Figure 5 The included angle α between the center line of the liquid outlet 112a and the center line of the gas outlet 11b is 30°-60°, i.e., 30°≤α≤60°, for example, 30°, 32°, 37°, 40°, 43°, 45°, 48°, 50°, 54°, 56°, 59°, 60°, etc.

[0076] In this embodiment, the angle between the center line of the liquid outlet 112a and the center line of the gas outlet 11b is set, which can facilitate the liquid outlet 112a to spray the high-pressure and high-speed gas at a more appropriate angle, so as to facilitate the contact between the high-pressure and high-speed gas and the atomized liquid, and then impact and split the atomized liquid, thereby improving the atomization effect, and at the same time, the mist outlet angle can be controlled within a good range.

[0077] In some embodiments, referring to Figure 7 and Figure 8 , in the projection along the plane perpendicular to the axial direction of the atomizing nozzle 11, the gas outlet 11b is in the shape of a sector.

[0078] In this embodiment, the sector-shaped gas outlet 11b can provide a larger coverage area, so that sufficient high-pressure and high-speed gas can be sprayed out of the gas outlet 11b, and at the same time, the sector-shaped gas outlet 11b can generate a relatively uniform distribution of high-pressure and high-speed gas, so that the high-pressure and high-speed gas is sprayed out more stably, facilitating the mixing of the high-pressure and high-speed gas and the atomized liquid, and increasing the atomization effect.

[0079] Exemplarily, the liquid outlet 112a can be in the shape of a circular hole, and the axis of the liquid outlet 112a is the center line of the liquid outlet 112a.

[0080] In some embodiments, referring to Figure 8 , the diameter of the liquid outlet 112a is 0.2mm (millimeter) to 0.4mm, for example, 0.2mm, 0.24mm, 0.25mm, 0.27mm, 0.3mm, 0.32mm, 0.34mm, 0.36mm, 0.38mm, 0.4mm, etc.

[0081] In this embodiment, the range of the diameter of the liquid outlet 112a is set, on the one hand, so that the atomized liquid with a larger viscosity will not block the liquid outlet 112a, and on the other hand, so that the size of the sprayed atomized liquid is appropriate, facilitating the atomization by the high-speed gas to form smaller atomized particles.

[0082] In some embodiments, referring to Figure 4 , the liquid channel 112b includes a first channel 112c and a second channel 112d in communication with each other, and the first channel 112c communicates the liquid outlet 112a and the second channel 112d.

[0083] In the direction close to the liquid outlet 112a, the flow passage cross-sectional area of the first channel 112c decreases.

[0084] Here, the decrease can be continuous or stepwise. The flow passage cross-sectional area of the first channel 112c refers to the flow area of the atomized liquid flowing through the first channel 112c.

[0085] That is, in the direction close to the atomization channel 111b, the flow passage cross-sectional area of the first channel 112c decreases, and when the flow passage area decreases, the flow rate of the atomized liquid sprayed from the liquid outlet 112a increases, thereby increasing the rate of the atomized liquid sprayed from the liquid outlet 112a.

[0086] In this embodiment, the flow passage cross-sectional area of the first channel 112c decreases, which facilitates the formation of a high-speed jet at the liquid outlet 112a, thereby increasing the kinetic energy of the atomized liquid. The high-pressure high-speed liquid can reduce the residence time of the liquid in the atomizing nozzle 11, thereby reducing the risk of clogging. The combination of the high-pressure high-speed liquid and the high-pressure high-speed airflow can facilitate the mixing of the gas and the liquid, and generate stronger shear force to break the atomized liquid into fine particles.

[0087] For example, the flow passage cross-sectional area of the first channel 112c continuously decreases to increase the stability of the liquid sprayed from the liquid outlet 112a, thereby increasing the atomization effect.

[0088] In some embodiments, referring to Figure 4 , the flow passage cross-sectional area of the second channel 112d decreases in the direction close to the liquid outlet 112a.

[0089] In this embodiment, the flow passage cross-sectional area of the second channel 112d decreases, which facilitates the atomized liquid to be sprayed from the liquid outlet 112a at a higher speed, thereby helping to break the atomized liquid into finer droplets.

[0090] In the embodiment in which the flow passage cross-sectional area of the first channel 112c decreases in the direction close to the communication port 111c, the flow passage cross-sectional area of the second channel 112d decreases, which can further increase the flow rate of the atomized liquid, thereby combining with the high-speed airflow, reducing the form of large particles, and making the spray more delicate.

[0091] For example, the flow passage cross-sectional area of the second channel 112d continuously decreases to increase the stability of the liquid sprayed from the liquid outlet 112d, thereby increasing the atomization effect.

[0092] For example, the flow passage cross-sectional area of the second channel 112d at any position is greater than the flow passage cross-sectional area of the first channel 112c. While having sufficient liquid inlet amount, the liquid flowing from the first channel 112c to the liquid outlet 112a also has a high enough pressure and flow rate.

[0093] Of course, in other embodiments, the second channel 112d can also be a constant-diameter channel.

[0094] The specific structure of the core 112 is not limited.

[0095] In some embodiments, referring to Figures 3 to 6, the core 112 includes a first cylinder portion 1121 and a second cylinder portion 1122, a space in the first cylinder portion 1121 defines a liquid channel 112b and a liquid outlet 112a, the second cylinder portion 1122 surrounds an outer periphery of a part of structure of the first cylinder portion 1121, and is connected with the first cylinder portion 1121 at an end away from the liquid outlet 112a in an axial direction, a circumferential inner surface of the second cylinder portion 1122 and a circumferential outer surface of the first cylinder portion 1121 have an annular space 1122a therebetween, the annular space 1122a, a space between another part of structure of the circumferential outer surface of the first cylinder portion 1121 and an inner surface of the accommodation space 111a jointly define an air channel 11a.

[0096] In this embodiment, the first cylinder portion 1121 and the second cylinder portion 1122 are arranged to separate the air channel 11a and the liquid channel 112b, that is, the air channel 11a and the liquid channel 112b are independent of each other and not communicated with each other, so that the gas-liquid mixing is avoided from being too early, and the efficiency of the gas-liquid mixing is improved. Meanwhile, the independent design of the air channel 11a and the liquid channel 112b can facilitate the optimization of the flow paths of the gas and the liquid respectively, and improve the overall performance. The annular space 1122a can facilitate the increase of the flow stability and uniformity of the high-pressure high-speed gas, and has sufficient flow space.

[0097] In some embodiments, referring to Figures 3 to 6 , the atomizing nozzle 11 is provided with an air inlet 11c, the air inlet 11c penetrates the side wall of the accommodation space 111a and the side wall of the annular space 1122a, and the air channel 11a is communicated with the air inlet 11c and the air outlet 11b.

[0098] That is, the high-pressure high-speed gas enters the air channel 11a through the air inlet 11c, and then exits the air channel 11a through the air outlet 11b.

[0099] In this embodiment, the air inlet 11c penetrates the side wall of the accommodation space 111a and the side wall of the annular space 1122a, that is, the high-pressure high-speed gas first enters the core 112 through the shell 111, and the core 112 does not need to be directly communicated with the external environment, so that the shell 111 can protect the core 112 and increase the arrangement stability of the core 112, meanwhile, the shell 111 and the core 112 jointly cooperate with air intake, which can increase the air intake stability, increase the impact resistance, and improve the structural stability of the atomizing nozzle 11.

[0100] In some embodiments, referring to Figure 4The first cylinder portion 1121 includes a first tapered portion 11211 and a second tapered portion 11212. The second tapered portion 11212 protrudes from the second cylinder portion 1122. The taper of the second tapered portion 11212 is greater than that of the first tapered portion 11211.
