[0032] An embodiment of the present application provides an atomization device, see Figure 1 , Figure 3 and Figure 6The atomizing device includes a housing 10 , an atomizing disk 20 , a driving assembly 30 and an impeller assembly 40 .

[0033] The housing 10 has a housing chamber 10a, one end of which has a mist outlet 10b, which is connected to the outside. The atomizing disk 20 is disposed in the housing chamber 10a.

[0034] The driving assembly 30 is disposed in the accommodating chamber 10 a and is located on a side of the atomizing disk 20 away from the mist outlet 10 b . The driving assembly 30 is drivingly connected to the atomizing disk 20 to drive the atomizing disk 20 to rotate.

[0035] The atomizing device of the present application is used to centrifugally atomize the atomizing medium to atomize it into fine mist. The atomizing device can be any type of centrifugal atomizing equipment, such as an atomizer for treating throat diseases, or a beauty atomizer for facial care.

[0036] The atomizing medium is a liquid medium that can be centrifugally atomized. The specific type of the atomizing medium can be determined according to the actual type of the atomizing disk 20 and the atomizing device. It can be a high-viscosity medium (such as glycerin) or other types of atomizing medium.

[0037] Specifically, the driving assembly 30 is a driving structure capable of driving the atomizing disk 20 to rotate, for example, the driving assembly 30 is a high-speed motor. Under the driving action of the driving assembly 30, the atomizing disk 20 can rotate around its own rotation axis. When the atomizing medium enters the accommodating chamber 10a and moves to the atomizing disk 20, the rotating atomizing disk 20 can centrifugally atomize the atomizing medium, thereby atomizing the atomizing medium into a small fine mist.

[0038] The specific connection mode between the driving assembly 30 and the atomizing disk 20 can be set according to actual conditions.

[0039] For example, the driving assembly 30 and the atomizing disk 20 are welded, bonded, keyed, or connected by a coupling, thereby meeting the requirements in different situations.

[0040] It can be understood that the driving assembly 30 drives the atomizing disk 20 to rotate so as to centrifugally atomize the atomizing medium into fine mist.

[0041] For example, the driving component 30 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, 40000r / min, 60000r / 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 20 can have a better 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.

[0042] 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.

[0043] 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.

[0044] The atomizing disk 20 may be made of metal or non-metal.

[0045] For example, the atomizing disk 20 is made of stainless steel, aluminum, copper, iron, resin or nylon.

[0046] Specifically, the atomizing disk 20 adopts the above-mentioned material, which can reduce the contact angle between the atomizing medium and the atomizing disk 20, thereby improving the wetting characteristics between the atomizing medium and the atomizing disk 20, so as to further improve the atomization effect and make the particle size of the atomizing medium after centrifugal atomization smaller.

[0047] Among them, the contact angle is the wetting angle, which refers to the angle from the solid-liquid interface through the liquid to the gas-liquid interface at the junction of solid, liquid and gas.

[0048] For example, the atomizing disk 20 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.

[0049] The impeller assembly 40 is rotatably disposed in the accommodating chamber 10a, and the impeller assembly 40 is located on the side of the atomizing disk 20 away from the mist outlet 10b. The impeller assembly 40 rotates to form an air flow path in the accommodating chamber 10a. The air flow path extends from the side of the atomizing disk 20 away from the mist outlet 10b to the mist outlet 10b, and the air flow path passes through the atomizing disk 20.

[0050] Specifically, the impeller assembly 40 and the drive assembly 30 are both located on the side of the atomizing disk 20 away from the mist outlet 10b, that is, the impeller assembly 40 and the drive assembly 30 are both located on the same side of the atomizing disk 20, and on the side opposite to the mist outlet 10b. Thus, the impeller assembly 40 and the drive assembly 30 are prevented from obstructing the atomized medium after centrifugal atomization from flowing out of the mist outlet 10b.

[0051] The airflow path refers to the flow path of the airflow formed in the accommodating chamber 10a due to the rotation of the impeller assembly 40 and the airflow passing through the accommodating chamber 10a.

[0052] The impeller assembly 40 can form an airflow moving toward the mist outlet 10b in the accommodating chamber 10a 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 20, it drives the atomized medium after centrifugal atomization by the atomizing disk 20 to move until it flows out from the mist outlet 10b.

[0053] In fact, the housing 10 further includes an airflow inlet, which is connected to the accommodating chamber 10a. Under the rotation of the impeller assembly 40, the airflow will flow into the accommodating chamber 10a from the airflow inlet, and flow through the atomizing disk 20 before flowing out from the mist outlet 10b. By forming the airflow inlet, it is convenient for external air to enter the accommodating chamber 10a through the airflow inlet and flow along the airflow path.

[0054] It should be noted that, since the atomizing disk 20 is located on the side of the impeller assembly 40 close to the mist outlet 10b, the air volume gradually decreases as the diameter of the atomizing disk 20 increases. If the diameter of the atomizing disk 20 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 10b, 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.

[0055] For example, the diameter of the atomizing disk 20 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.

[0056] Preferably, the diameter of the atomizing disk 20 is greater than or equal to 24 mm and less than or equal to 32 mm. As the diameter of the atomizing disk 20 gradually increases, the particle size of the atomizing medium particles after centrifugal atomization gradually decreases.

[0057] The impeller assembly 40 also rotates around its own rotation axis, and forms a single-direction airflow through the rotation. In fact, the impeller assembly 40 is an impeller structure using an axial flow method. The axial flow method allows the airflow to flow through the atomizing disk 20 along the airflow path and flow out from the mist outlet 10b.

[0058] It should be noted that the impeller assembly 40 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.

[0059] In addition, the impeller assembly 40 is rotatably arranged in the accommodating chamber 10a, which means that the impeller assembly 40 can rotate in the accommodating chamber 10a, and when the atomizing device is in working state, the impeller assembly 40 rotates, and when the atomizing device stops working, the impeller assembly 40 does not rotate.

[0060] The impeller assembly 40 may rotate in any manner.

[0061] For example, see Figures 4 to 6 The impeller assembly 40 includes a second drive motor and an impeller. The second drive motor is drivingly connected to the impeller to drive the impeller to rotate.

[0062] 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 10a. Thus, on the one hand, the misting effect can be improved, and on the other hand, the impeller assembly 40 is independent of the drive assembly 30, and the speed of the second drive motor can be the same as that of the drive assembly 30, or a different speed, so that it can be set according to actual requirements, which can meet the actual needs in various situations.

[0063] It should be noted that the impeller is a structure with blades, such as a fan, which can generate airflow by rotating.

[0064] 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.

[0065] For example, see Figure 2 and Figure 3 The driving assembly 30 is drivingly connected to the impeller assembly 40 to drive the impeller assembly 40 to rotate.

[0066] Specifically, in addition to being connected to the atomizing disk 20, the driving assembly 30 is also connected to the impeller assembly 40, so that the impeller assembly 40 can be driven to rotate synchronously under the driving action of the driving assembly 30, and the integrated design of the driving assembly 30, the impeller assembly 40 and the atomizing disk 20 can be realized. Therefore, the impeller assembly 40 and the atomizing disk 20 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.

[0067] 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.

[0068] The atomizing device in the embodiment of the present application includes a housing 10, an atomizing disk 20, a driving assembly 30 and an impeller assembly 40. On the one hand, the driving assembly 30 is arranged in the accommodating chamber 10a and is located on the side of the atomizing disk 20 away from the mist outlet 10b, and the driving assembly 30 is connected to the atomizing disk 20 to drive the atomizing disk 20 to rotate. Thus, under the driving action of the driving assembly 30, the atomizing disk 20 can rotate around the axis of rotation to centrifugally atomize the atomizing medium moving to the atomizing disk 20. On the other hand, the impeller assembly 40 is rotatably arranged in the accommodating chamber 10a and is located on the side of the atomizing disk 20 away from the mist outlet 10b. The impeller assembly 40 rotates to form an airflow flow path from the side of the atomizing disk 20 away from the mist outlet 10b to the mist outlet 10b in the accommodating chamber 10a, and the airflow flow path passes through the atomizing disk 20. Therefore, the impeller assembly 40 can form an airflow moving toward the mist outlet 10b in the accommodating chamber 10a through rotation. When the airflow flows through the atomizing disk 20, it can bring the atomized medium that has been centrifugally atomized by the atomizing disk 20 to the mist outlet 10b and output it, which can effectively reduce the adhesion of the atomized medium to the inside of the shell 10 and the atomizing disk 20, thereby enhancing the mist outlet effect of the atomizing device, and further improving the atomization effect of the atomizing device.

[0069] 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.

[0070] In one embodiment, please refer to Figure 3 The impeller assembly 40 is located on the side of the driving assembly 30 away from the atomizing disk 20. The driving assembly 30 is a first driving motor. The driving shaft 31 of the first driving motor extends to the atomizing disk 20 at one end close to the mist outlet 10b. The driving shaft 31 is drivingly connected to the atomizing disk 20. The driving shaft 31 extends to the impeller assembly 40 at one end away from the mist outlet 10b. The driving shaft 31 is drivingly connected to the impeller assembly 40.

[0071] Specifically, the driving assembly 30 is a first driving motor, which is connected to the impeller assembly 40 and the atomizing disk 20 respectively through a driving shaft 31 to synchronously drive the two to rotate around the axis.

[0072] The impeller assembly 40 and the atomizing disk 20 are respectively located on opposite sides of the driving assembly 30. The airflow generated by the rotation of the impeller assembly 40 will flow through the impeller assembly 40, the driving assembly 30 and the atomizing disk 20 in sequence, and the atomized medium after centrifugal atomization at the atomizing disk 20 is taken out from the atomizing outlet 10b. Therefore, the impeller assembly 40 and the atomizing disk 20 can be separated by the driving assembly 30 to avoid interference between the impeller assembly 40 and the atomizing disk 20, and the atomized medium can also be reduced from adhering to the impeller assembly 40.

[0073] Both opposite ends of the driving shaft 31 along the extension direction are driving ends, which are respectively connected to the impeller assembly 40 and the atomizing disk 20 for driving. Thus, the impeller assembly 40 and the atomizing disk 20 can be synchronously driven to rotate by one motor.

[0074] It should be noted that since the impeller assembly 40 and the atomizing disk 20 are driven by the same drive shaft 31 , the axial length of the drive shaft 31 needs to be accurately considered, which needs to be able to satisfy the requirement of stably rotating the impeller assembly 40 and the atomizing disk 20 at high speed.

[0075] In other embodiments, the impeller assembly 40 and the atomizing disk 20 may also be located on the same side of the first driving motor, that is, the impeller assembly 40 and the atomizing disk 20 are driven by the same end of the driving shaft 31 of the first driving motor.

[0076] In one embodiment, the driving assembly 30 includes a power supply board having a through hole, and one end of the driving shaft 31 away from the mist outlet 10 b passes through the through hole to be drivingly connected to the impeller assembly 40 .

[0077] Specifically, since both opposite ends of the driving shaft 31 are driving ends, by providing a through hole on the power board for the driving shaft 31 to pass through, on the one hand, it is convenient to drive and connect the driving shaft 31 with the impeller assembly 40. On the other hand, it can avoid potential conflicts between the driving shaft 31 and the power line of the power board, and it is convenient to arrange the power board of the driving assembly 30, so as to optimize the overall structural layout of the driving assembly 30, and ensure the stability and efficiency of the operation of the driving assembly 30, the impeller assembly 40 and the atomizing disk 20.

[0078] In one embodiment, please refer to Figure 3 and Figure 6 The area of ​​the shell 10 located on the side of the atomizer disk 20 close to the mist outlet 10b is the outlet section 11, and the outlet section 11 includes a first section 111 and a contraction section 112. The contraction section 112 is located between the outlet section 11 and the mist outlet 10b. The cross-sectional opening size of the first section 111 is larger than the opening size of the mist outlet 10b. From the side close to the atomizer disk 20 to the side close to the mist outlet 10b, the cross-sectional opening size of the contraction section 112 gradually decreases.

[0079] Specifically, the name of the first section 111 is only used for the convenience of description to distinguish it from the contraction section 112. The use of the description "first" does not mean that the outlet section 11 must also have a "second section", "third section", or "fourth section". Of course, it does not mean that the outlet section 11 only has the first section 111 and the contraction section 112. Its specific structure can be set according to actual conditions.

[0080] The inner cavity of the outlet section 11 is a part of the accommodating chamber 10a, and the contraction section 112 is used to contract the size of the inner cavity toward the mist outlet 10b, thereby facilitating the airflow to drive the atomized medium after centrifugal atomization to flow out through the mist outlet 10b.

[0081] The cross-sectional opening size of the first section 111 is larger than the opening size of the mist outlet 10b, so that the first section 111 can be easily connected to the area of ​​the housing 10 located on the side of the atomizer disk 20 away from the mist outlet 10b, so as to accommodate the atomizer disk 20. The opening size of the mist outlet 10b should not be too large to avoid too small air flow rate at the mist outlet 10b, which is not conducive to user use.

[0082] The contraction section 112 is used for transition between the first section 111 and the mist outlet 10b. By setting the contraction section 112, it is possible to avoid the formation of a step between the first section 111 and the mist outlet 10b due to excessive change in the opening size, thereby avoiding the mist outlet effect being affected by the formation of the step.

[0083] Along the extension direction of the airflow path (i.e., the direction from the side of the atomizing disk 20 away from the mist outlet 10b to the mist outlet 10b), the cross-sectional opening size of the first section 111 may be constant, or may gradually decrease according to actual conditions.

[0084] It should be noted that the specific contraction setting method of the contraction section 112 can be set according to actual conditions.

[0085] For example, the curvature of the contraction section 112 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 112 gradually increases, the airflow velocity of the mist outlet 10b can be gradually increased. The above curvature can ensure that the mist outlet 10b has a good misting effect while meeting the needs of users.

[0086] 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.

[0087] In addition, the contraction section 112 is located between the first section 111 and the mist outlet 10b, and the mist outlet 10b can be located at the end of the contraction section 112 away from the first section 111. According to actual conditions, a certain distance can be formed between the contraction section 112 and the mist outlet 10b.

[0088] 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 112 and the mist outlet 10b 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 112 gradually approaches the mist outlet 10b, the airflow velocity out of the mist outlet 10b 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 10b has a good misting effect.

[0089] The working state of the atomizing device refers to the state in which the atomizing device is started and performs centrifugal atomization.

[0090] 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.

[0091] In a specific embodiment, the outlet section 11 further includes a second section located between the contraction section 112 and the mist outlet 10b, the mist outlet 10b is located at one end of the second section away from the contraction section 112, and the cross-sectional opening size of the second section is the same as the opening size of the mist outlet 10b.

[0092] In one embodiment, the area of ​​the housing 10 located on the side of the atomizing disk 20 close to the mist outlet 10b is the outlet section 11, and the extension length of the outlet section 11 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 11 is greater than or equal to 20 mm and less than or equal to 26 mm.

[0093] Specifically, the distance between the atomizer disc 20 and the mist outlet 10b can be set according to actual conditions, but the distance between the atomizer disc 20 and the mist outlet 10b 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 10b. The outlet section 11 adopts the above-mentioned extended length, which can make the airflow flowing out of the mist outlet 10b have a better air volume.

[0094] Of course, according to actual conditions, the extension length of the outlet section 11 may also adopt other specific dimensions, such as 13 mm or 35 mm.

[0095] For example, the extension length of the outlet section 11 is 13 mm, and the air volume of the mist outlet 10b is 1.3 m 3 / h.

[0096] For example, the extension length of the outlet section 11 is 23 mm, and the air volume of the mist outlet 10b is 1.9 m 3 / h.

[0097] For example, the extension length of the outlet section 11 is 35 mm, and the air volume of the mist outlet 10b is 1.4 m 3 / h.

[0098] In one embodiment, please refer to Figure 2 The housing 10 has a liquid supply port 10c, which is located between the atomizing disk 20 and the mist outlet 10b, and a liquid supply rate of the liquid supply port 10c 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.

[0099] Specifically, the liquid supply port 10c is used to introduce the atomized medium into the atomizing disk 20, so that the atomizing disk 20 can centrifugally atomize the atomized medium. For example, the liquid supply port 10c is located on the top side of the atomizing disk 20, and the drive assembly 30 is located on the bottom side of the atomizing disk 20. Thus, the atomized medium flowing into the container from the liquid supply port 10c can fall to the atomizing disk 20 under the action of gravity for centrifugal atomization.

[0100] The liquid supply speed of the liquid supply port 10c 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 10c should not be too large, as a large liquid supply speed will reduce the atomization effect and affect the atomization effect. The specific value can be set according to actual conditions.

[0101] In one embodiment, the atomizing device further comprises a motor clamping device, which is located in the accommodating chamber 10a and is arranged between the atomizing disc 20 and the driving assembly 30. The motor clamping device is connected to the inner wall surface of the housing 10, and the motor clamping device has a through hole connecting the side close to the atomizing disc 20 and the side away from the atomizing disc 20. The opening size of a part of the area of ​​the through hole away from the end of the atomizing disc 20 is increased to form a snap-in groove, and a part of the area of ​​the driving assembly 30 is snapped into the snap-in groove, and the driving shaft of the driving assembly 30 passes through the through hole to be driven and connected with the atomizing disc 20. Thus, by forming the motor clamping device, the driving assembly 30 can be stably installed in the housing 10 to improve the stability of the driving assembly during operation.

[0102] At that time, at the end of the driving assembly 30 away from the atomizing disk 20 , a partial area of ​​the housing 10 extends into the accommodating cavity 10 a to be connected to the end of the driving assembly 30 away from the atomizing disk 20 , thereby further improving the stability of the driving assembly 30 .
