Description

Technical Field

[0001] The utility model relates to the technical field of atomization, in particular to an atomization disc and an atomization device. Background Art

[0002] In the related art, centrifugal atomization technology can effectively convert liquid into fine mist particles. When the atomizing medium is a high-viscosity atomizing medium, the atomizing medium is prone to increase in viscosity, which makes it more difficult to break the liquid film, thereby reducing the atomization effect. In the related art, the viscosity of the atomizing medium is reduced by heating, and then the atomizing medium is atomized. However, this will make the overall structure of the atomizing device complex, and its volume will also increase, which is not convenient for users to use. Utility Model Content

[0074] In this application, the "rotation direction" orientation or position relationship is based on the attached Figure 3 or Fig.11 It should be understood that these directional terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application.

[0075] An embodiment of the present application provides an atomizing disk 30, which is used to atomize an atomizing medium. The atomizing disk 30 includes a disk body 10, which has an atomizing cavity 10b and an atomizing surface 10a. The disk body 10 includes a disk body 12 and a guide flange 11. The guide flange 11 is arranged around the outer edge of the disk body 12 in the circumferential direction, and the guide flange 11 extends toward a side of the disk body 10 having the atomizing surface 10a, and the atomizing cavity 10b is formed by the atomizing surface 10a. The atomizing disk 30 can rotate around the rotation axis so that the disk body 10 performs centrifugal atomization on the atomizing medium in the atomizing cavity 10b.

[0076] Another embodiment of the present application provides an atomization device, which includes a housing 40 , a drive assembly 50 , a power supply, and an atomization disk 30 . The drive assembly 50 , the power supply, and the atomization disk 30 are disposed in the housing 40 .

[0077] The atomizing disk 30 is used to atomize the atomizing medium. The atomizing disk 30 includes a disk body 10. The disk body 10 has an atomizing cavity 10b and an atomizing surface 10a. The disk body 10 includes a disk main body 12 and a guide flange 11. The guide flange 11 is arranged around the circumferential outer edge of the disk main body 12, and the guide flange 11 extends toward the side of the disk body 10 having the atomizing surface 10a. The atomizing cavity 10b is formed by enclosing the atomizing surface 10a.

[0078] Specifically, the atomizing medium is a liquid medium that can be centrifugally atomized, which can break the liquid film under the action of centrifugal force by contacting the rotating atomizing disk 30, thereby forming a fine mist with a smaller particle size. The specific type of the atomizing medium can be determined according to the actual type of the atomizing device, and can be a high-viscosity medium (such as glycerin) or other types of atomizing media.

[0079] The atomizing disk 30 including the disk body 10 means that, in some embodiments, the atomizing disk 30 may only include the disk body 10, that is, the disk body 10 is the atomizing disk 30. According to actual conditions, in other embodiments, in addition to the disk body 10, the atomizing disk 30 may also include other structures arranged on the disk body 10.

[0080] The disk body 10 of the atomizing disk 30 is not a flat disk. In fact, the guide flange 11 is a structure that guides and strengthens the airflow and is folded and extended relative to the disk body 12. Specifically, the guide flange 11 is folded and extended relative to the disk body 12, and its extension direction is toward the side of the disk body 10 having the atomizing surface 10a, thereby forming the guide flange 11.

[0081] It can be understood that the guide flange 11 is only an extension of the outer edge of the disc body 10 along the circumferential direction. There is a certain angle between the guide flange 11 and the disc body 12, and the range of the angle can be determined according to actual conditions.

[0082] For example, the included angle between the guide flange 11 and the disk body 12 is greater than or equal to 30° and less than or equal to 150°. Thus, it can be ensured that the guide flange 11 can guide the airflow well.

[0083] For example, the angle between the guide flange 11 and the disk body 12 is 30°, 40°, 45°, 50°, 60°, 70°, 80°, 90°, 100°, 110°, 120°, 130°, 135°, 140° or 150°.

[0084] When the included angle between the guide flange 11 and the disk body 12 is 90°, the atomization effect can be better and the generation of large-sized droplets can be prevented.

[0085] In addition, the specific shape of the guide flange 11 can also be set according to actual conditions. For example, the wall surface of the guide flange 11 located in the atomizing chamber 10b is an arc surface, thereby better guiding the airflow in the atomizing chamber 10b.

[0086] It can be understood that, in fact, the wall surface of the guide flange 11 located in the atomization chamber 10 b is the area where the atomization surface 10 a is located at the guide flange 11 .

[0087] In addition, the curvature of the wall surface of the guide flange 11 located in the atomization chamber 10b can be set according to actual conditions.

[0088] For example, the radius of the arc surface is greater than or equal to 0.1 times the diameter of the disk body 12, and less than or equal to 0.6 times the diameter of the disk body 12. Thus, a better flow guiding effect can be achieved.

[0089] For example, the radius of the arc surface is 0.1 times, 0.2 times, 0.25 times, 0.3 times, 0.4 times, 0.5 times or 0.6 times the diameter of the disk body 12 .

[0090] When the radius of the arc surface is 0.25 times the diameter of the disk body 12 , the guiding flange 11 can better guide the airflow.

[0091] It should be noted that the guide flange 11 extends toward the side of the disk body 10 having the atomized surface 10a, which specifically means that the outer edge of the disk body 10 along the circumferential direction extends toward the side of the disk body 10 having the atomized surface 10a to form the guide flange 11. The extension direction is the same as the orientation of the atomized surface 10a on the disk body 10.

[0092] The atomizing surface 10a is a side surface of one side of the disc body 10, and the setting direction of the atomizing surface 10a on the disc body 10 is consistent with the extension direction of the guide flange 11. The atomizing surface 10a can be used to contact with the atomizing medium to centrifugally atomize the atomizing medium. In fact, the guide flange 11 and the disc body 12 jointly form the atomizing surface 10a.

[0093] Since the atomizing surface 10a is not a plane, the enclosed area inside it is the atomizing chamber 10b. When the atomizing device provides the atomizing medium into the atomizing chamber 10b, the atomizing medium can enter the atomizing chamber 10b to contact the atomizing surface 10a. At the same time, due to the high-speed rotation of the atomizing disk 30, the atomizing surface 10a can centrifugally atomize the atomizing medium.

[0094] It should be noted that not only the atomizing surface 10a can centrifugally atomize the atomizing medium. In fact, when the atomizing device provides the atomizing medium, since the atomizing disk 30 rotates at a high speed as a whole, any area of ​​the atomizing disk 30 that contacts the atomizing medium has a centrifugal atomization effect.

[0095] In addition, the specific material and shape of the atomized surface 10a can also be set according to actual conditions. Fig.13 The area of ​​the atomized surface 10a outside the guide flange 11 is a curved surface.

[0096] For example, the disk body 10 of the atomizing disk 30 is a U-shaped disk body. The U-shaped disk body can facilitate the airflow to carry the atomized atomized medium out. Figure 1 The area of ​​the atomized surface 10a outside the guide flange 11 is a plane, such as a circle with a radius of 1 mm, 4 mm or 7 mm.

[0097] The atomizing disk 30 may have an overall structure made of the same material, and other regions of the atomizing disk 30 may also be made of a material different from that of the atomizing surface 10 a.

[0098] The atomizing disk 30 may be made of metal or non-metal.

[0099] For example, at least the atomizing surface 10 a of the atomizing disk 30 is made of stainless steel, aluminum, copper, iron, resin, or nylon.

[0100] Specifically, the atomizing surface 10a of the atomizing disk 30 adopts the above-mentioned material, which can reduce the contact angle between the atomizing medium and the atomizing surface 10a, thereby improving the wetting characteristics between the atomizing medium and the atomizing surface 10a, thereby further improving the atomization effect, and making the particle size of the atomizing medium after centrifugal atomization smaller. Among them, the contact angle is the wetting angle, which refers to the angle between the solid-liquid interface through the liquid interior to the gas-liquid interface at the junction of the solid, liquid and gas phases.

[0101] For example, the atomizing disk 30 is made of nylon, and the atomizing medium is glycerin. The contact angles between glycerin and nylon are successively smaller than the contact angles between glycerin and aluminum, the contact angles between glycerin and copper, and the contact angles between glycerin and stainless steel.

[0102] See also Figure 1 and Figure 2 As the extension length of the guide flange 11 increases, the enhancement effect of the guide flange 11 on the airflow movement gradually increases. However, the extension length of the guide flange 11 should not be too short. If it is too short, the enhancement effect on the airflow movement will not be obvious. If it is too long, the atomized medium will be more concentrated in the atomizing chamber 10b, which will reduce the atomization effect.

[0103] For example, the extension length of the guide flange 11 is greater than or equal to 4 mm and less than or equal to 10 mm, such as 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm or 10 mm. The extension length can be set according to actual conditions.

[0104] The extension length of the guide flange 11 refers to the length of the guide flange 11 extending toward the side of the plate body 10 having the atomized surface 10a. Figure 1 Middle A.

[0105] It should be noted that, in other embodiments, according to actual needs, the extension length of the guide flange 11 may also be greater than 0 mm or less than 4 mm.

[0106] The driving assembly 50 is disposed on a side of the atomizing disk 30 away from the atomizing surface 10 a , and the driving assembly 50 is drivingly connected to the atomizing disk 30 , and the power source is electrically connected to the driving assembly 50 .

[0107] When the atomizing device is in working state, the atomizing disk 30 can rotate around the rotation axis under the driving action of the driving assembly 50, so that the disk body 10 can centrifugally atomize the atomizing medium in the atomizing chamber 10b.

[0108] Specifically, the atomizing disk 30 of the present application is a centrifugal atomizing disk, that is, the atomizing disk 30 can cooperate with the driving assembly 50, so that under the driving action of the driving assembly 50, the atomizing medium supplied can be atomized into fine mist by rotating around its own rotation axis.

[0109] Furthermore, the rotation axis of the atomizing disk 30 is not an actual structural line, but a virtual line around which the atomizing disk 30 rotates.

[0110] The atomizing device of the present application is used to centrifugally atomize the atomizing medium to atomize it into a small fine mist. The atomizing device can be any type of centrifugal atomizing equipment, such as an atomizer for treating throat diseases, an atomizer for treating respiratory diseases, or a beauty atomizer for facial care.

[0111] The power supply is electrically connected to the driving assembly 50, and the power supply can provide electric energy to the driving assembly 50, thereby driving the atomizing disk 30 to rotate. The driving assembly 50 is a driving structure capable of driving the atomizing disk 30 to rotate. The driving assembly 50 needs to be able to satisfy the requirement of making the atomizing disk 30 rotate at a high speed.

[0112] For example, the driving component 50 is a driving motor, and the speed of the driving motor is greater than or equal to 20000 r / min, such as 20000 r / min, 30000 r / min, 40000 r / min, 50000 r / min, 60000 r / min, 70000 r / min, or 80000 r / min.

[0113] It should be noted that, as the speed of the driving motor increases, the overall action range of the airflow generated in the housing 40 can be significantly expanded, and the particle size of the atomized medium after centrifugal atomization can also be gradually reduced.

[0114] The driving connection mode between the driving motor and the atomizing disk 30 can be set according to actual conditions. For example, a connecting hole is provided at the rotation axis of the disk body 10, and the driving shaft of the driving motor is inserted into the connecting hole to drive the disk body 10 to rotate.

[0115] In the related art, the atomizing disk is a flat disk with a planar structure. The airflow generated by the rotation of the atomizing disk is weak. When the viscosity of the atomizing medium is high, the atomizing medium will adhere to the atomizing disk more, resulting in a problem of poor atomization effect.

[0116] The disk body 10 of the atomizing device of the present application has an atomizing chamber 10b and an atomizing surface 10a. The disk body 10 includes a disk body 12 and a guide flange 11. The guide flange 11 is arranged around the outer edge of the disk body 12 along the circumferential direction, and the guide flange 11 extends toward the side of the disk body 10 having the atomizing surface 10a. When the atomizing device is in a working state, the atomizing disk 30 can rotate around the rotation axis under the driving action of the driving assembly 50, so that the disk body 10 centrifugally atomizes the atomizing medium in the atomizing chamber 10b. Since the disk body 10 is formed with the guide flange 11, during the rotation of the atomizing disk 30, the guide flange 11 can strengthen the airflow generated by the rotation of the atomizing disk 30, so that the atomizing medium after centrifugal atomization can flow out more with the airflow, thereby improving the atomizing effect of the atomizing device. Therefore, when dealing with a high-viscosity atomization medium, the atomization device can realize centrifugal atomization of the high-viscosity atomization medium at room temperature, and can have a good atomization effect without the need for an additional heating device to heat the atomization medium. Its structure is simple, and the volume of the atomization device can be reduced, thereby making it easier for users to use.

[0117] Compared with a flat disk, the atomizing disk 30 of the present application has a better atomization effect and a smaller atomized particle size, can produce droplets of a larger concentration, and has a stronger atomization ability.

[0118] In addition, the guide flange 11 extends toward the side of the disk body 10 having the atomizing surface 10a, so that during the rotation of the atomizing disk 30, the airflow in the atomizing chamber 10b drives the atomized medium after centrifugal atomization to move to the guide flange 11, and then, under the action of the guide flange 11, it can have a tendency to move along the direction of the rotation axis.

[0119] In one embodiment, the housing 40 has a liquid supply port 40c, which is located on a side of the atomizing disk 30 away from the driving assembly 50, so as to supply the atomizing medium into the atomizing chamber 10b.

[0120] Specifically, the liquid supply port 40c is used to introduce the atomized medium into the atomizing disk 30 so that the atomizing disk 30 can centrifugally atomize the atomized medium. For example, the side of the atomizing disk 30 having the atomizing surface 10a is the top side, the liquid supply port is located on the top side of the atomizing disk 30, and the drive assembly 50 is located on the bottom side of the atomizing disk 30.

[0121] It should be noted that the liquid supply port 40c is only for supplying the atomizing medium to the atomizing disk 30. In fact, the atomizing medium is pushed by a stepping motor or pumped by a peristaltic pump to the liquid supply port 40c and enters the atomizing chamber 10b.

[0122] In addition, the liquid supply speed of the atomizing device should not be too small to avoid a small amount of mist from the atomizing device. The liquid supply speed of the atomizing device should not be too large to avoid affecting the atomization effect. The specific value can be set according to the actual situation.

[0123] For example, the atomizing device supplies the atomizing medium into the atomizing chamber 10b through the liquid supply port at a liquid supply rate greater than or equal to 3 ml / min and less than or equal to 9 ml / min, such as 3 ml / min, 6 ml / min or 9 ml / min.

[0124] In fact, the mist outlet of the atomizing device is located on the side of the atomizing disk 30 with the atomizing surface 10a. The drive assembly 50 is located on the side of the atomizing disk 30 away from the atomizing surface 10a, which can prevent the drive assembly 50 from blocking the atomized medium after centrifugal atomization from flowing out of the mist outlet.

[0125] The driving assembly 50 being located on the side of the atomizing disk 30 facing away from the atomizing surface 10 a means that the driving assembly 50 and the atomizing surface 10 a are not located on the same side of the atomizing disk 30 , but are located on opposite sides.

[0126] In one embodiment, please refer to Figures 3 to 11 The atomizing disk 30 has a guide portion 20, and at least a portion of the guide portion 20 is located in the atomizing chamber 10b to guide the atomizing medium after centrifugal atomization to move along the direction of the rotation axis.

[0127] Specifically, the guide portion 20 is a guide structure having the effect of guiding the flow of air, and can be a solid structure, such as a guide plate, a guide rib 21, etc. It can also be a virtual structure such as a guide groove 20a, a guide channel, etc.

[0128] The guide part 20 can guide the atomized medium after centrifugal atomization to move along the direction of the rotation axis. The movement of the atomized medium along the direction of the rotation axis means that the atomized medium can move along the extension direction of the rotation axis, that is, along the axial direction of the atomizing disk 30.

[0129] In fact, in the atomizing device, the mist outlet of the atomizing device is located on the side of the atomizing disk 30 having the atomizing surface 10a. The airflow in the atomizing device flows from the side of the atomizing disk 30 away from the atomizing surface 10a to the side of the atomizing disk 30 having the atomizing surface 10a, so as to drive the atomized medium after centrifugal atomization to flow out from the mist outlet. By providing the guide part 20, the airflow near the atomizing disk 30 can be bent in the direction of the rotation axis, so as to realize a single mist outlet in the direction of the mist outlet.

[0130] It should be noted that the atomized medium after centrifugal atomization has a tendency to move radially toward the atomizing disk 30 under the action of centrifugal force, and has a tendency to move along the direction of the rotation axis under the guiding action of the guide part 20.

[0131] In addition, the specific structure of the guide portion 20 can be set according to actual conditions.

[0132] For example, see Fig.10 and Fig.11 The guide portion 20 is a guide rib 21, which is disposed in the atomizing chamber 10b, and the angle between the guide rib 21 and the atomizing surface 10a is greater than or equal to 10° and less than or equal to 170°. Thus, it is possible to avoid the angle between the guide rib 21 and the atomizing surface 10a being too small to reduce the airflow guiding effect of the guide rib 21, and it is possible to facilitate the effect of achieving a single direction of the mist outlet.

[0133] It should be noted that when the angle between the guide rib 21 and the atomizing surface 10a located at the bottom area of ​​the atomizing disk 30 is between 10° and 170°, the atomizing disk 30 can have a better atomizing effect.

[0134] For another example, the guide portion 20 is a guide rib 21, and the guide rib 21 is disposed in the atomizing chamber 10b, and the ratio of the shortest distance from the guide rib 21 to the center of the disk body 10 to the diameter of the disk body 12 is greater than or equal to 1 / 4 and less than or equal to 5 / 6. For example, the ratio of the shortest distance from the guide rib 21 to the center of the disk body 10 to the diameter of the disk body 12 is: 3 / 10, or 1 / 3, or 1 / 2, or 7 / 10, or 3 / 4, or 7 / 9.

[0135] Specifically, the shortest distance from the guide rib 21 to the center of the disc body 10 refers to the minimum value of the distance between each area on the guide rib 21 and the center of the disc body 10. The ratio of the above shortest distance to the diameter of the disc body 12 is controlled within the range of 1 / 4 to 5 / 6. On the one hand, it can ensure that the guide rib 21 will not be too short to reduce the effect of guiding the flow of air, and on the other hand, it can also ensure that the guide rib 21 will not be too long to cause material waste, and will not affect the effect of single mist discharge along the direction of the mist outlet.

[0136] It should be noted that the number of guide ribs 21 is not limited. Only one guide rib 21 may be provided, or a plurality of guide ribs 21 may be provided.

[0137] For example, the disc body 10 is provided with n guide ribs 21, n≥2 and n is a positive integer, and the guide ribs 21 are arranged at intervals around the rotation axis. Thus, the guide ribs 21 can guide the airflow and atomizing medium in the atomizing chamber 10b more evenly.

[0138] Specifically, the guide ribs 21 may be arranged at equal intervals around the rotation axis, thereby further improving the uniformity of air flow. Of course, according to actual conditions, the guide ribs 21 may also be arranged at unequal intervals around the rotation axis.

[0139] In addition, the arrangement of the guide ribs 21 in the atomizing chamber 10b can be set according to actual conditions. It can be directly attached to the atomizing surface 10a, or it can be spaced apart from the atomizing surface 10a and installed on the disk body 10 through other connecting structures.

[0140] On the other hand, when the disk body 10 of the atomizing disk 30 is a U-shaped disk body, it cooperates with the flow guiding ribs 21 to achieve a greater degree of airflow deflection, so as to further enhance the working ability of the atomizing disk 30 on the airflow.

[0141] In one embodiment, please refer to Fig.10 Along the direction of the rotation axis, an atomizing chamber opening 10c is provided on the side of the atomizing chamber 10b away from the driving assembly 50, and along the direction of the rotation axis, the guide rib 21 extends to the atomizing chamber opening 10c.

[0142] Specifically, the direction along the rotation axis refers to the direction extending along the rotation axis, that is, the axial direction of the atomizing disk 30. Along the rotation axis, the atomizing chamber opening 10c and the driving assembly 50 are located on opposite sides of the atomizing chamber 10b, respectively. In addition, the guide rib 21 is flush with the atomizing chamber opening 10c along the rotation axis.

[0143] Therefore, the guide ribs 21 extend along the direction of the rotation axis, thereby enhancing the effect of the guide portion 20 in guiding the airflow to move along the direction of the rotation axis, so as to enhance the ability of the atomizing disk 30 to do work on the airflow.

[0144] In addition, the guide rib 21 may also extend in other directions. For example, one end of the guide rib 21 is located on the disk body 12 , and the other end of the guide rib 21 extends in a direction perpendicular to the rotation axis, and the guide rib 21 extends to the guide flange 11 .

[0145] Specifically, the direction perpendicular to the rotation axis refers to a direction perpendicular to the extending direction of the rotation axis, which is actually the radial direction of the atomizing disk 30 . The guide ribs 21 extend radially from the disk body 12 to the guide flange 11 .

[0146] Therefore, the guide ribs 21 extend in a direction perpendicular to the rotation axis, that is, the guide ribs 21 also extend radially along the atomizing disk 30. Therefore, the guide ribs 21 can reduce the speed of the circumferential movement of the airflow in the atomizing chamber 10b around the rotation axis to increase the speed of the airflow in the radial direction, thereby enabling the airflow to form an axial jet through deflection under the action of the guide flange 11 on the outer edge of the disk body 10.

[0147] It should be noted that the guide ribs 21 may extend in a direction perpendicular to the rotation axis or in the direction of the rotation axis, or may extend in two directions simultaneously.

[0148] It should be noted that the length of the guide rib 21 along the direction of the rotation axis should not be too large, otherwise it will affect the mist discharge effect, but the length of the guide rib 21 along the direction of the rotation axis should not be too small, otherwise it will lead to a weak guide effect of the guide rib 21. Therefore, by extending the guide rib 21 along the direction of the rotation axis to the opening 10c of the atomization chamber, it is possible to better guide the airflow to drive the atomized medium after centrifugal atomization to move along the axial direction while avoiding affecting the mist discharge effect.

[0149] In addition, the guide ribs 21 extend to the guide flange 11 in a direction away from the rotation axis, which can also maximize the guide ribs 21 to guide the airflow in the atomization chamber 10 b to move radially and deflect it through the guide flange 11 .

[0150] In addition, as the extension length of the guide flange 11 increases, the guide flange 11 cooperates with the guide rib 21 to enhance the movement of the airflow on the side of the disk body 10 having the atomizing surface 10a along the direction of the rotation axis, which can further improve the effect of the single air outlet.

[0151] In one embodiment, please refer to Fig.10 and Fig.11 The guide rib 21 has a windward side 21a and a leeward side 21b, the windward side 21a is located on the side of the guide rib 21 along the rotation direction of the atomizing disk 30, and the leeward side 21b is located on the side of the guide rib 21 away from the rotation direction of the atomizing disk 30, wherein the leeward side 21b is concave in shape and the windward side 21a is convex in shape.

[0152] Specifically, the windward side 21a of the guide rib 21 refers to the side of the guide rib 21 on one side along the rotation direction, and the leeward side 21b refers to the side of the guide rib 21 on the side opposite to the rotation direction. The rotation direction here refers to the direction in which the atomizing disk 30 rotates when the atomizing disk 30 is working. In fact, the windward side 21a and the leeward side 21b are respectively located on opposite sides of the guide rib 21. During the rotation of the atomizing disk 30, the windward side 21a is located in front of the leeward side 21b along the rotation direction.

[0153] The leeward side 21b of the guide rib 21 is relatively concave, and the windward side 21a is relatively convex. Thus, the guide rib 21 can be bent relative to the radial direction of the atomizing disk 30, and bend from the side close to the axis of rotation to the side away from the axis of rotation, toward the side opposite to the direction of rotation. By making the leeward side 21b concave and the windward side 21a convex, the wind resistance of the guide rib 21 can be reduced while the guide rib 21 has a better guiding effect, and the airflow and the atomized medium can also be better guided to move radially to the guide flange 11 for deflection. Thus, on the one hand, the air intake effect can be better and a greater inlet velocity can be generated, and on the other hand, it can be more conducive to centrifugal atomization.

[0154] Of course, in other embodiments, according to actual conditions, the guide ribs 21 may also be linear ribs extending along the radial direction of the atomizing disk 30 .

[0155] In one embodiment, please refer to Figures 3 to 8 The guide portion 20 is a guide groove 20a, and a part of the disc body 10 is disconnected to form the guide groove 20a. The disc body 10 has a departure surface 10d on the side away from the atomizing surface 10a. The guide groove 20a connects the side of the disc body 10 having the atomizing surface 10a and the side having the departure surface 10d to guide the airflow to move the atomized medium after centrifugal atomization along the direction of the rotation axis. By forming the guide groove 20a, the airflow near the atomizing disc 30 can be better deflected along the axial direction, so as to realize a single mist outlet.

[0156] Specifically, the guide groove 20a is a wind passage groove that penetrates the disc body 10 along the rotation axis direction, and is formed by disconnecting a part of the disc body 10. Since one side of the guide groove 20a is connected to the atomizing surface 10a, the connection point between the guide groove 20a and the atomizing surface 10a is also located in the atomizing chamber 10b.

[0157] As the atomizing disk 30 rotates, the airflow can flow from the side of the disk body 10 away from the surface 10d through the guide groove 20a to the atomizing cavity 10b on the side of the atomizing surface 10a, and then can drive the atomized medium after centrifugal atomization to move along the direction of the rotation axis.

[0158] It can be understood that, in fact, the atomized medium after centrifugal atomization has a tendency to move along the direction of the rotation axis under the action of the guide groove 20a, and has a tendency to move radially along the atomizing disk 30 under the action of centrifugal force, so it is a movement formed by the superposition of the two.

[0159] It should be noted that the specific configuration of the guide groove 20a is not limited and can be set according to actual conditions.

[0160] For example, see Figures 3 to 8One end of the guide groove 20a is located on the disk body 12, and the other end of the guide groove 20a extends to the guide flange 11 along the direction perpendicular to the rotation axis, and the end of the guide groove 20a extending to the guide flange 11 is open or closed.

[0161] Specifically, part of the guide groove 20 a is located on the disc body 12 , and part of the guide groove 20 a is located on the guide flange 11 , and extends from the disc body 12 toward the guide flange 11 .

[0162] Part of the area at the guide flange 11 is disconnected to form a part of the guide groove 20a. In fact, the guide groove 20a can be extended to the outer edge of the guide flange 11 and open, that is, the side of the guide groove 20a extending to the outer edge of the guide flange 11 is not closed, but open. By making this side of the guide groove 20a open, the guide groove 20a can be better connected to the outside world to improve the diversion effect. In this way, the air intake effect of the guide groove 20a can be improved, and the effect of the airflow deflecting along the axial direction to form an axial jet can be further improved.

[0163] Of course, according to actual conditions, in some embodiments, the end of the guide groove 20a extending to the guide flange 11 may also be closed.

[0164] For example, see Figure 7 and Figure 8 The guide groove 20a has groove walls 22 on both sides opposite to each other along the width direction, the groove walls 22 extend from the atomizing surface 10a to the away surface 10d, and the groove walls 22 are inclined toward the rotation direction of the atomizing disk 30 when working. In fact, the groove walls 22 on both sides of the guide groove 20a can be inclined relative to the direction of the rotation axis, and are inclined in a direction that is consistent with the rotation direction. Therefore, during the rotation of the atomizing disk 30, it can further facilitate the airflow to enter the atomizing chamber 10b along the guide groove 20a, so as to further enhance the guiding effect of the guide groove 20a.

[0165] Moreover, as the inclination angle of the guide groove 20a gradually decreases, the tendency of the airflow to move along the direction of the rotation axis gradually decreases. The specific value of the inclination angle of the guide groove 20a can be set according to actual conditions.

[0166] For example, the inclination angle of the groove wall 22 is greater than or equal to 15° and less than or equal to 45°. For example, the inclination angle of the groove wall 22 is 15°, 20°, 25°, 30°, 35°, 40°, or 45°.

[0167] It should be noted that, in other embodiments, according to actual conditions, the groove wall 22 on the side of the guide groove 20a may also extend along the direction of the rotation axis, that is, it is not inclined.

[0168] Also, see Figure 4 and Figure 5 The number of guide grooves 20a can also be set according to actual conditions, and can be one or more, such as 2, 3, 4, 5, 6, 7 or 8. Adjacent guide grooves 20a can be arranged at intervals, and can be arranged at equal intervals or at non-equal intervals.

[0169] Exemplarily, the disc body 10 has a plurality of guide grooves 20a, which are arranged at intervals around the circumference of the rotation axis. By providing a plurality of guide grooves 20a, the atomizing disc 30 can further improve the working ability of the airflow, so that the airflow can have a greater axial deflection, a longer jet range, and a greater axial velocity.

[0170] For example, the number of the guide grooves 20a is greater than or equal to 1 and less than or equal to 6. For example, the number of the guide grooves 20a is 1, 3, 4 or 6.

[0171] In addition, the specific shape and size of the guide groove 20a can also be set according to actual conditions.

[0172] For example, see Figure 3 and Figure 4 , the width of the guide groove 20a is greater than or equal to 1 mm and less than or equal to 3 mm. For example, the width of the guide groove 20a is 1 mm, 2 mm or 3 mm.

[0173] It should be noted that the guide groove 20a adopts the above-mentioned width size, which is a better size range obtained by comprehensive consideration of the structure, strength, processing and manufacturing, and service life, so that the guide groove 20a can have a better guiding effect and can better improve the atomization effect of the atomization disk 30. At the same time, it can avoid the problem of poor atomization effect caused by the guide groove 20a being too large, and the problem of difficult processing caused by the guide groove 20a being too small.

[0174] As the width of the guide groove 20a gradually increases, the tendency of the airflow to move along the direction of the rotation axis gradually increases.

[0175] Of course, in other embodiments, the guide groove 20a may also adopt other width dimensions, such as 4 mm or 6 mm.

[0176] For another example, the guide groove 20a extends in a direction away from the rotation axis, and the width of the guide groove 20a is the same along the direction away from the rotation axis. In other words, the guide groove 20a has a uniform groove width, which can facilitate processing and manufacturing.

[0177] Of course, the guide groove 20a can also be formed by gradually increasing the width along the extending direction of the guide groove 20a, thereby facilitating the guide groove 20a to guide the airflow.

[0178] It should be noted that the guide groove 20 a extends in a direction away from the rotation axis, which means that one end of the guide groove 20 a extends toward a side away from the rotation axis (ie, the outside of the disk body 10 ), for example, extends in the radial direction of the disk body 10 .

[0179] For example, the width of the guide groove 20a at one end close to the rotation axis is 1 mm, the width of the guide groove 20a gradually increases along the extension direction, and the width of the guide groove 20a at one end away from the rotation axis is 4 mm or 6 mm.

[0180] In one embodiment, please refer to Figure 6 A partial area away from the surface 10d is recessed to form an air inlet groove 10e, and one side of the guide groove 20a along the rotation direction of the atomizing disk 30 is connected to the air inlet groove 10e.

[0181] Specifically, in order to facilitate the airflow to enter the guide groove 20a, an air inlet groove 10e is set on the back surface 10d of the atomizer disk 30, and the air inlet groove 10e is set on the side of the guide groove 20a along the rotation direction of the atomizer disk 30. It can facilitate the airflow to enter the guide groove 20a through the air inlet groove 10e, thereby enhancing the guide effect of the guide groove 20a.

[0182] In one embodiment, the depth of the concave inlet groove 10e gradually decreases along the rotation direction of the atomizing disk 30. Thus, the concave surface of the air inlet groove 10e can form an inclined slope, which can be used to guide the airflow into the guide groove 20a, and at the same time, the concave of the atomizing disk 30 away from the surface 10d can be less, which can ensure the structural strength of the atomizing disk 30.

[0183] In a specific embodiment, the atomizing disk 30 is made of nylon, the atomizing medium is glycerol, and its concentration is 100%. As the liquid supply speed of the atomizing medium increases from 3ml / min to 9ml / min, the atomized particle size also shows an increasing trend. When the concentration of glycerol is changed to 80% and 40%, at the same rotation speed, there is no obvious regularity between the atomized particle size and the glycerol concentration.

[0184] In a specific embodiment, the atomizing medium is glycerin, and its viscosity is 100%. As the rotation speed increases from 40,000 rpm to 80,000 rpm, the atomized particle size shows a downward trend. Fig.14 , Fig.16 and Fig.19 The atomizing device includes an impeller assembly 60. The housing 40 has a receiving chamber 40a, one end of which has a mist outlet 40b, and the mist outlet 40b is connected to the outside. The atomizing disk 30 and the driving assembly 50 are arranged in the receiving chamber 40a. The driving assembly 50 is located on the side of the atomizing disk 30 away from the mist outlet 40b.

[0185] Specifically, the driving assembly 50 is a driving structure capable of driving the atomizing disk 30 to rotate, for example, the driving assembly 50 is a high-speed motor. Under the driving action of the driving assembly 50, the atomizing disk 30 can rotate around its own rotation axis. When the atomizing medium enters the accommodating chamber 40a and moves to the atomizing disk 30, the rotating atomizing disk 30 can centrifugally atomize the atomizing medium, thereby atomizing the atomizing medium into a small fine mist.

[0186] The specific connection method between the driving assembly 50 and the atomizing disk 30 can be set according to actual conditions.

[0187] For example, the driving assembly 50 and the atomizing disk 30 are welded, bonded, keyed, or connected by a coupling, thereby meeting the requirements in different situations.

[0188] It can be understood that the driving assembly 50 drives the atomizing disk 30 to rotate so as to centrifugally atomize the atomizing medium into fine mist.

[0189] For example, the driving component 50 is a first driving motor, and the speed of the first driving motor is greater than or equal to 20000r / min. For example, 20000r / min, 30000r / min, 40000r / min, 50000r / min, 60000r / min, 70000r / min, 80000r / min, or 100000r / min. The use of a high-speed motor can atomize the atomizing medium into a fine mist of micron level, so that the atomizing disk 30 can have a good centrifugal atomization effect on the atomizing medium. As a result, the atomizing device can atomize high-viscosity media at room temperature without the need to add a heating device.

[0190] At the same time, as the rotation speed of the first driving motor gradually increases, the particle size of the atomized medium after centrifugal atomization also gradually decreases as the rotation speed increases.

[0191] It should be noted that the size of the first driving motor should not be too large, such as an outer diameter of 28.8 mm or 30 mm. Therefore, a high-speed, small-sized motor can be used to achieve small-scale centrifugal atomization.

[0192] The impeller assembly 60 is rotatably disposed in the accommodating chamber 40a, and the impeller assembly 60 is located on the side of the atomizing disk 30 away from the mist outlet 40b. The impeller assembly 60 rotates to form an air flow path in the accommodating chamber 40a. The air flow path extends from the side of the atomizing disk 30 away from the mist outlet 40b to the mist outlet 40b, and the air flow path passes through the atomizing disk 30.

[0193] Specifically, the impeller assembly 60 and the drive assembly 50 are both located on the side of the atomizing disk 30 away from the mist outlet 40b, that is, the impeller assembly 60 and the drive assembly 50 are both located on the same side of the atomizing disk 30, and on the side opposite to the mist outlet 40b. Thus, the impeller assembly 60 and the drive assembly 50 are prevented from obstructing the atomized medium after centrifugal atomization from flowing out of the mist outlet 40b.

[0194] The airflow path refers to the flow path of the airflow formed in the accommodating chamber 40a due to the rotation of the impeller assembly 60 and the airflow passing through the accommodating chamber 40a.

[0195] The impeller assembly 60 can form an airflow moving toward the mist outlet 40b in the accommodating chamber 40a by rotating, thereby enabling the atomizing device to have a single-direction mist outlet effect. The airflow flows along the airflow path, and when flowing through the atomizing disk 30, it drives the atomized medium after centrifugal atomization by the atomizing disk 30 to move until it flows out from the mist outlet 40b.

[0196] In fact, the housing 40 also includes an airflow inlet, which is connected to the accommodating chamber 40a. Under the rotation of the impeller assembly 60, the airflow will flow into the accommodating chamber 40a from the airflow inlet, and flow through the atomizing disk 30, and then flow out from the mist outlet 40b. By forming the airflow inlet, it is convenient for external air to enter the accommodating chamber 40a through the airflow inlet and flow along the airflow path.

[0197] It should be noted that, since the atomizing disk 30 is located on the side of the impeller assembly 60 close to the mist outlet 40b, the air volume gradually decreases as the diameter of the atomizing disk 30 increases. If the diameter of the atomizing disk 30 is too large or too small, it cannot form an effective single-direction mist outlet. If the diameter is too large, it will hinder the flow of airflow, which is not conducive to the airflow to carry the atomized medium after centrifugal atomization out of the mist outlet 40b, and make the noise louder. However, if the diameter is too small, it will lead to insufficient atomization and less mist outlet, which will lead to poor atomization effect of the atomizing device.

[0198] For example, the diameter of the atomizing disk 30 is greater than or equal to 20 mm and less than or equal to 34 mm, such as 20 mm, 22 mm, 24 mm, 26 mm, 28 mm, 32 mm, 34 mm, 36 mm or 39 mm.

[0199] Preferably, the diameter of the atomizing disk 30 is greater than or equal to 24 mm and less than or equal to 32 mm. As the diameter of the atomizing disk 30 gradually increases, the particle size of the atomizing medium particles after centrifugal atomization gradually decreases.

[0200] The impeller assembly 60 also rotates around its own rotation axis, and forms a single-direction airflow through the rotation. In fact, the impeller assembly 60 is an impeller structure using an axial flow method. The axial flow method allows the airflow to flow through the atomizing disk 30 along the airflow path and flow out from the mist outlet 40b.

[0201] It should be noted that the impeller assembly 60 may be an entire structure that rotates around the axis, or only a partial area or a partial structure that rotates, as long as it can form an airflow path through rotation.

[0202] In addition, the impeller assembly 60 is rotatably arranged in the accommodating chamber 40a, which means that the impeller assembly 60 can rotate in the accommodating chamber 40a, and when the atomizing device is in working state, the impeller assembly 60 rotates, and when the atomizing device stops working, the impeller assembly 60 does not rotate.

[0203] The impeller assembly 60 may rotate in any manner.

[0204] For example, see Figures 17 to 19 The impeller assembly 60 includes a second drive motor and an impeller. The second drive motor is drivingly connected to the impeller to drive the impeller to rotate.

[0205] Specifically, the second drive motor does not rotate, but drives the impeller to rotate to form an airflow along the airflow path in the accommodating chamber 40a. Thus, on the one hand, the misting effect can be improved, and on the other hand, the impeller assembly 60 is independent of the drive assembly 50, and the speed of the second drive motor can be the same as that of the drive assembly 50, or a different speed, so that it can be set according to actual requirements, which can meet the actual needs in various situations.

[0206] It should be noted that the impeller is a structure with blades, such as a fan, which can generate airflow by rotating.

[0207] For example, the second driving motor can adopt a small motor structure with high wind power and low noise, thereby being able to achieve miniaturization while satisfying the atomization effect and having a good silent effect.

[0208] For example, see Fig.15 and Fig.16 The driving assembly 50 is drivingly connected to the impeller assembly 60 to drive the impeller assembly 60 to rotate.

[0209] Specifically, in addition to being connected to the atomizing disk 30, the driving assembly 50 is also connected to the impeller assembly 60, so that the impeller assembly 60 can be driven to rotate synchronously under the driving action of the driving assembly 50, and the integrated design of the driving assembly 50, the impeller assembly 60 and the atomizing disk 30 can be realized. Therefore, the impeller assembly 60 and the atomizing disk 30 can be driven to rotate synchronously through a driving structure, which can simplify the size of the atomizing device and reduce the complexity of the structure.

[0210] In the related art, there is also a method of heating the atomizing medium by adding a heating device to increase the temperature of the atomizing medium to reduce the viscosity and thus improve the misting effect. However, the above technical solution of adding a heating device makes the atomizing device complex in structure, bulky in size, and inconvenient to use.

[0211] The atomizing device in the embodiment of the present application includes a housing 40, an atomizing disk 30, a driving assembly 50 and an impeller assembly 60. On the one hand, the driving assembly 50 is arranged in the accommodating chamber 40a and is located on the side of the atomizing disk 30 away from the mist outlet 40b, and the driving assembly 50 is connected to the atomizing disk 30 to drive the atomizing disk 30 to rotate. Thus, under the driving action of the driving assembly 50, the atomizing disk 30 can rotate around the axis of rotation to centrifugally atomize the atomizing medium moving to the atomizing disk 30. On the other hand, the impeller assembly 60 is rotatably arranged in the accommodating chamber 40a and is located on the side of the atomizing disk 30 away from the mist outlet 40b. The impeller assembly 60 rotates to form an airflow flow path from the side of the atomizing disk 30 away from the mist outlet 40b to the mist outlet 40b in the accommodating chamber 40a, and the airflow flow path passes through the atomizing disk 30. Therefore, the impeller assembly 60 can form an airflow moving toward the mist outlet 40b in the accommodating chamber 40a through rotation. When the airflow flows through the atomizing disk 30, it can bring the atomized medium that has been centrifugally atomized by the atomizing disk 30 to the mist outlet 40b and output it, which can effectively reduce the adhesion of the atomized medium to the inside of the shell 40 and the atomizing disk 30, thereby enhancing the mist outlet effect of the atomizing device, and further improving the atomization effect of the atomizing device.

[0212] It can be seen that the atomizing device of the present application can centrifugally atomize the atomizing medium at room temperature and has a good atomizing effect. It does not require an additional heating device, thereby simplifying the structure of the atomizing device and reducing its volume for ease of use by users.

[0213] In one embodiment, please refer to Fig.16The impeller assembly 60 is located on the side of the driving assembly 50 away from the atomizing disk 30. The driving assembly 50 is a first driving motor. The driving shaft 51 of the first driving motor extends to the atomizing disk 30 at one end close to the mist outlet 40b. The driving shaft 51 is drivingly connected to the atomizing disk 30. The driving shaft 51 extends to the impeller assembly 60 at one end away from the mist outlet 40b. The driving shaft 51 is drivingly connected to the impeller assembly 60.

[0214] Specifically, the driving assembly 50 is a first driving motor, which is connected to the impeller assembly 60 and the atomizing disk 30 respectively through a driving shaft 51 to synchronously drive the two to rotate around the axis.

[0215] The impeller assembly 60 and the atomizing disk 30 are respectively located on opposite sides of the driving assembly 50. The airflow generated by the rotation of the impeller assembly 60 will flow through the impeller assembly 60, the driving assembly 50 and the atomizing disk 30 in sequence, and the atomized medium after centrifugal atomization at the atomizing disk 30 is taken out from the atomizing outlet 40b. Therefore, the impeller assembly 60 and the atomizing disk 30 can be separated by the driving assembly 50 to avoid interference between the impeller assembly 60 and the atomizing disk 30, and the atomized medium can also be reduced from adhering to the impeller assembly 60.

[0216] The two opposite ends of the driving shaft 51 along the extension direction are both driving ends, which are respectively connected to the impeller assembly 60 and the atomizing disk 30 for driving. Thus, the impeller assembly 60 and the atomizing disk 30 can be synchronously driven to rotate by one motor.

[0217] It should be noted that since the impeller assembly 60 and the atomizing disk 30 are driven by the same drive shaft 51 , the axial length of the drive shaft 51 needs to be accurately considered, which needs to be able to satisfy the requirement of stable and high-speed rotation of the impeller assembly 60 and the atomizing disk 30 .

[0218] In other embodiments, the impeller assembly 60 and the atomizing disk 30 may also be located on the same side of the first driving motor, that is, the impeller assembly 60 and the atomizing disk 30 are driven by the same end of the driving shaft 51 of the first driving motor.

[0219] In one embodiment, the driving assembly 50 includes a power supply board having a through hole, and one end of the driving shaft 51 away from the mist outlet 40 b passes through the through hole to be drivingly connected to the impeller assembly 60 .

[0220] Specifically, since both opposite ends of the driving shaft 51 are driving ends, by providing a through hole on the power board for the driving shaft 51 to pass through, on the one hand, it is convenient to drive and connect the driving shaft 51 with the impeller assembly 60. On the other hand, it can avoid potential conflicts between the driving shaft 51 and the power line of the power board, and it can be convenient to arrange the power board of the driving assembly 50, so as to optimize the overall structural layout of the driving assembly 50, and ensure the stability and efficiency of the operation of the driving assembly 50, the impeller assembly 60 and the atomizing disk 30.

[0221] In one embodiment, please refer to Fig.16 and Fig.19 The area of ​​the shell 40 located on the side of the atomizer disk 30 close to the mist outlet 40b is the outlet section 41, and the outlet section 41 includes a first section 411 and a contraction section 412. The contraction section 412 is located between the outlet section 41 and the mist outlet 40b. The cross-sectional opening size of the first section 411 is larger than the opening size of the mist outlet 40b. From the side close to the atomizer disk 30 to the side close to the mist outlet 40b, the cross-sectional opening size of the contraction section 412 gradually decreases.

[0222] Specifically, the name of the first section 411 is only used for the convenience of description to distinguish it from the contraction section 412. The use of the description "first" does not mean that the outlet section 41 must also have a "second section", "third section", or "fourth section". Of course, it does not mean that the outlet section 41 only has the first section 411 and the contraction section 412. Its specific structure can be set according to actual conditions.

[0223] The inner cavity of the outlet section 41 is a part of the accommodating cavity 40a, and the contraction section 412 is used to contract the size of the inner cavity toward the mist outlet 40b, thereby facilitating the airflow to drive the atomized medium after centrifugal atomization to flow out through the mist outlet 40b.

[0224] The cross-sectional opening size of the first section 411 is larger than the opening size of the mist outlet 40b, so that the first section 411 can be easily connected to the area of ​​the housing 40 located on the side of the atomizing disk 30 away from the mist outlet 40b, so as to accommodate the atomizing disk 30. The opening size of the mist outlet 40b should not be too large to avoid too small air flow velocity at the mist outlet 40b, which is not conducive to user use.

[0225] The contraction section 412 is used for transition between the first section 411 and the mist outlet 40b. By setting the contraction section 412, it is possible to avoid the formation of a step between the first section 411 and the mist outlet 40b due to excessive change in the opening size, thereby avoiding the mist outlet effect being affected by the formation of the step.

[0226] Along the extension direction of the airflow path (ie, the direction from the side of the atomizing disk 30 away from the mist outlet 40b to the mist outlet 40b), the cross-sectional opening size of the first section 411 may be constant, or may be gradually reduced according to actual conditions.

[0227] It should be noted that the specific contraction setting method of the contraction section 412 can be set according to actual conditions.

[0228] For example, the curvature of the contraction section 412 is greater than or equal to 25 m -1 And less than or equal to 80m -1 For example, 25m -1 、33.1m-1 、76.9m -1 or 80m -1 As the curvature of the contraction section 412 gradually increases, the airflow velocity of the mist outlet 40b can be gradually increased. The above curvature can ensure that the mist outlet 40b has a good misting effect while meeting the needs of users.

[0229] It can be understood that curvature refers to the rotation rate of the tangent direction angle at a certain point on the curve to the arc length. The larger the curvature, the greater the curvature of the curve.

[0230] In addition, the contraction section 412 is located between the first section 411 and the mist outlet 40b, and the mist outlet 40b can be located at the end of the contraction section 412 away from the first section 411. According to actual conditions, a certain distance can be formed between the contraction section 412 and the mist outlet 40b.

[0231] For example, when the atomizing device is in working state, along the extension direction of the airflow path, the minimum distance between the contraction section 412 and the mist outlet 40b is greater than or equal to 9 mm and less than or equal to 21 mm. For example, 9 mm, 12.5 mm, 15 mm, 17 mm, 20.5 mm or 21 mm. As the contraction section 412 gradually approaches the mist outlet 40b, the airflow velocity out of the mist outlet 40b can be gradually increased. By adopting the above distance range, it is possible to meet the needs of users while ensuring that the mist outlet 40b has a good misting effect.

[0232] The working state of the atomizing device refers to the state in which the atomizing device is started and performs centrifugal atomization.

[0233] The minimum distance between the contraction section 112 and the mist outlet 10 b refers to the minimum value of the distance between each area on the contraction section 112 and the mist outlet 10 b.

[0234] In a specific embodiment, the outlet section 41 also includes a second section located between the contraction section 412 and the mist outlet 40b, and the mist outlet 40b is located at one end of the second section away from the contraction section 412, and the cross-sectional opening size of the second section is the same as the opening size of the mist outlet 40b.

[0235] In one embodiment, the area of ​​the housing 40 located on the side of the atomizing disk 30 close to the mist outlet 40b is the outlet section 41, and the extension length of the outlet section 41 is greater than or equal to 10 mm and less than or equal to 39 mm. For example, 10 mm, 12 mm, 14 mm, 16 mm, 18 mm, 20 mm, 23 mm, 26 mm, 29 mm, 33 mm, 36 mm or 39 mm. Preferably, the extension length of the outlet section 41 is greater than or equal to 20 mm and less than or equal to 26 mm.

[0236] Specifically, the distance between the atomizing disk 30 and the mist outlet 40b can be set according to actual conditions, but the distance between the atomizing disk 30 and the mist outlet 40b should not be too large. Too large or too small a distance will result in a decrease in the air volume of the airflow flowing out of the mist outlet 40b. The outlet section 41 adopts the above-mentioned extended length, so that the airflow flowing out of the mist outlet 40b has a better air volume.

[0237] Of course, according to actual conditions, the extension length of the outlet section 41 may also adopt other specific dimensions, such as 13 mm or 35 mm.

[0238] For example, the extension length of the outlet section 41 is 13 mm, and the air volume of the mist outlet 40b is 1.3 m 3 / h.

[0239] For example, the extension length of the outlet section 41 is 23 mm, and the air volume of the mist outlet 40b is 1.9 m 3 / h.

[0240] For example, the extension length of the outlet section 41 is 35 mm, and the air volume of the mist outlet 40b is 1.4 m 3 / h.

[0241] In one embodiment, please refer to Fig.15 The housing 40 has a liquid supply port 40c, which is located between the atomizing disk 30 and the mist outlet 40b, and a liquid supply rate of the liquid supply port 40c is greater than or equal to 3 ml / min and less than or equal to 9 ml / min, such as 3 ml / min, 6 ml / min or 9 ml / min.

[0242] Specifically, the liquid supply port 40c is used to introduce the atomized medium into the atomizing disk 30, so that the atomizing disk 30 can centrifugally atomize the atomized medium. For example, the liquid supply port 40c is located on the top side of the atomizing disk 30, and the drive assembly 50 is located on the bottom side of the atomizing disk 30. Thus, the atomized medium flowing into the container from the liquid supply port 40c can fall to the atomizing disk 30 under the action of gravity for centrifugal atomization.

[0243] The liquid supply speed of the liquid supply port 40c should not be too small to avoid a small amount of mist from the atomizing device. The liquid supply speed of the liquid supply port 40c should not be too large, as a large liquid supply speed will reduce the atomizing effect and affect the atomizing effect. The specific value can be set according to actual conditions.

[0244] In one embodiment, the atomizing device further comprises a motor clamping device, which is located in the accommodating chamber 40a and is arranged between the atomizing disc 30 and the driving assembly 50. The motor clamping device is connected to the inner wall surface of the housing 40, and the motor clamping device has a through hole connecting the side close to the atomizing disc 30 and the side away from the atomizing disc 30. The opening size of a part of the area of ​​the through hole away from the end of the atomizing disc 30 is increased to form a snap-in groove, and a part of the area of ​​the driving assembly 50 is snapped into the snap-in groove, and the driving shaft of the driving assembly 50 passes through the through hole to be driven and connected with the atomizing disc 30. Thus, by forming the motor clamping device, the driving assembly 50 can be stably installed in the housing 40 to improve the stability of the driving assembly during operation.

[0245] At that time, at the end of the driving assembly 50 away from the atomizing disk 30 , a partial area of ​​the housing 40 extends into the accommodating cavity 40 a to be connected to the end of the driving assembly 50 away from the atomizing disk 30 , thereby further improving the stability of the driving assembly 50 .
