Description

Technical Field

[0001] The present application relates to the technical field of aerosol atomization, and in particular to an atomizer and an atomization device. Background Art

[0002] Heat Not Burning (HNB) electronic atomization devices can be used to heat aerosol products to generate aerosols. In the existing technology, most HNB devices use circumferential heating or central heating to make the aerosol product directly contact the heating element. The heating element heats the aerosol product by heat conduction, causing the part of the aerosol product that is in direct contact with the heating element to be over-baked, resulting in a burning problem. At the same time, the part of the aerosol product that is not in contact with the heating element cannot be baked, resulting in uneven baking of the aerosol product, thereby affecting the atomization effect of the aerosol product.

Therefore, the specification and drawings are only for the purpose of clearly describing a particular embodiment and do not imply a required composition and / or sequence.

[0038] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0039] The present application provides an atomizing device, such as Figures 1 to 3 As shown, the atomizing device may include a shell 1, a power supply component 2 and an atomizer 100. The power supply component 2 may be arranged in the shell 1, the atomizer 100 may be electrically connected to the power supply component 2, and the power supply component 2 may supply power to the atomizer 100 so that the atomizer 100 heats the aerosol product 3 and generates an aerosol.

[0040] Among them, the housing 1 can be set to a box-shaped or long strip-shaped structural shape, the power supply component 2 can include electronic components such as a circuit board, a battery, and a controller, the atomizer 100 can be electrically connected to the circuit board, the circuit board can be electrically connected to the battery, the controller can be electrically connected to the circuit board, and the battery can power the atomizer 100. In other embodiments, the atomizer 100 can also be directly electrically connected to the battery. In addition, the power supply component 2 can also be set outside the housing 1, and the power supply component 2 can be detachably connected to the housing 1. This application does not impose any special restrictions on the specific structure of the housing 1 and the power supply component 2.

[0041] In order to better atomize the aerosol product 3, the present application also provides an atomizer 100, such as Figures 1 to 5 As shown, the atomizer 100 may include an atomizer 110, a heating component 120 and an air pump component 130. The atomizer 110 may include an atomizer tube 111 and a receiving portion 112 connected to each other. The atomizer tube 111 has a lumen 1110. The receiving portion 112 has a receiving cavity 1120 communicating with the lumen 1110. The atomizer tube 111 is provided with at least one atomizer hole 1100 communicating with the lumen 1110. The atomizer tube 111 may be used to insert an aerosol product. 3; the heating component 120 is arranged in the accommodating cavity 1120, and the heating component 120 is provided with a heat exchange channel 1200 connected to the tube cavity 1110; the inlet of the air pump component 130 can be connected to the external airflow, and the outlet of the air pump component 130 is connected to the heat exchange channel 1200. The air pump component 130 can be used to blow pressurized air into the heat exchange channel 1200, so that the heated pressurized airflow flows from the tube cavity 1110 to the atomization hole 1100 to atomize the aerosol product 3.

[0042] When the atomizer 100 atomizes the aerosol product 3, the air pump assembly 130 can blow pressurized air into the heat exchange channel 1200 of the heating assembly 120. The heating assembly 120 heats the pressurized airflow, forming a high-pressure hot airflow that flows into the lumen 1110 of the atomizing tube 111. Because the atomizing tube 111 is inserted into the aerosol product 3, the high-pressure hot airflow ejected from the atomizing hole 1100 can quickly penetrate all parts of the aerosol product 3. Furthermore, the high-pressure hot airflow can be forced to circulate within the aerosol product 3, thereby ensuring that all parts of the aerosol product 3 are fully and evenly atomized under the action of the high-pressure hot airflow, thereby improving the atomization efficiency of the aerosol product 3. Furthermore, atomizing the aerosol product 3 through forced convection of the high-pressure hot airflow avoids direct contact between the heating element and the aerosol product 3, thereby preventing the aerosol product 3 from being overheated and preventing it from being scorched.

[0043] Among them, the housing 1 can be provided with an air hole, and the inlet of the air pump assembly 130 can be connected to the air hole on the housing 1, so that the external air flow can flow into the air pump assembly 130. Alternatively, the inlet of the air pump assembly 130 can also be directly set in the housing 1, and the external air flow can flow into the housing 1 and then into the air pump assembly 130. The present application does not impose any special restrictions on the specific location of the inlet of the air pump assembly 130. The atomizing tube 111 can be provided with one, two or more atomizing holes 1100, and the present application does not impose any special restrictions on the specific number of atomizing holes 1100.

[0044] In addition, the heating component 120 can be connected in parallel with the air pump component 130, and the controller can control the operation or stop of the heating component 120 and the air pump component 130 respectively. Alternatively, the heating component 120 can also be connected in series with the air pump component 130, and the controller can control the heating component 120 and the air pump component 130 to operate or stop simultaneously. This application does not impose any special restrictions on the control method of the operation of the heating component 120 and the air pump component 130.

[0045] In some embodiments, as Figures 2 to 5 As shown, the air pump assembly 130 may include an air duct component 131 and an air pump 132 connected to each other; the air duct component 131 has an air duct 1310, the atomizing component 110 is connected to the air duct component 131, the heat exchange channel 1200 is connected to one end of the air duct 1310, the outlet of the air pump 132 is connected to the other end of the air duct 1310, and the inlet of the air pump 132 is connected to the external airflow.

[0046] Depending on the structural shape of the housing 1, the heating component 120 and the air pump 132 can be positioned at different locations within the housing 1. The airway component 131 can be configured as a T-shaped tube, a straight tube, or a curved tube, depending on the specific locations of the heating component 120 and the air pump 132 within the housing 1. This allows the outlet of the air pump 132 to communicate with the heat exchange channel 1200 via the air channel 1310, thereby allowing the air pump 132 to blow pressurized air into the heat exchange channel 1200. This application does not impose any particular restrictions on the specific shape of the airway component 131.

[0047] In some embodiments, the outlet flow rate of the air pump 132 can be set to 200 mL / min-750 mL / min, the outlet pressure of the air pump 132 can be set to 60 kPa-95 kPa, and the noise of the air pump 132 can be set to be lower than 35 dB.

[0048] When the outlet flow rate of the air pump 132 is lower than 200mL / min and the outlet pressure is lower than 60kPa, the pressure of the air flow flowing into the lumen 1110 is relatively small, and the atomization effect of the hot air flow on the aerosol product 3 is poor. When the outlet flow rate of the air pump 132 is higher than 750mL / min and the outlet pressure is higher than 95kPa, the noise of the air pump 132 is relatively large, which has a significant impact on the user's experience. Therefore, the outlet flow rate of the air pump 132 can be set to 200mL / min, 300mL / min, 500mL / min or 750mL / min, and the outlet pressure of the air pump 132 can be set to 60kPa, 70kPa, 80kPa or 95kPa, so that while ensuring the atomization effect, the noise of the air pump 132 can be controlled within 35dB. This application does not impose any special restrictions on the specific parameters of the outlet flow rate and outlet pressure of the air pump 132.

[0049] In some embodiments, as Figure 4 and Figure 5 As shown, the heating component 120 may include a heating element 122 and a heat exchange element 121; the heat exchange channel 1200 is arranged on the heat exchange element 121, and the heat exchange element 121 is connected to the heating element 122. The heating element 122 can be used to conduct heat to the heat exchange element 121 so that the heat exchange element 121 heats the pressurized airflow.

[0050] The heating element 122 is connected to the heat exchange element 121 and transfers heat to the heat exchange element 121 through heat transfer. The heat exchange element 121 then heats the pressurized airflow, preventing direct contact between the heating element 122 and the aerosol product 3, thereby preventing the aerosol product 3 from burning. The heat exchange element 121 can be made of a material with high thermal conductivity, such as aluminum alloy, copper, or aluminum nitride, to reduce heat loss from the heating element 122. This application does not impose any specific restrictions on the specific material of the heat exchange element 121.

[0051] In some embodiments, as Figure 4 and Figure 5 As shown, the heating component 120 may further include a heat insulating member 123 ; the heat insulating member 123 may be coated on the outer wall of the heat exchanging member 121 , and the heat exchanging member 121 may be connected to the inner wall of the accommodating portion 112 through the heat insulating member 123 .

[0052] The thermal insulation member 123, which covers the outer wall of the heat exchanger 121, can reduce heat loss from the heat exchanger 121, thereby providing thermal insulation for the heat exchanger 121. The thermal insulation member 123 can be made of materials such as silicone or rubber, allowing the heat exchanger 121 to be sealed within the accommodating cavity 1120 of the accommodating portion 112 via the thermal insulation member 123. This application does not impose any particular restrictions on the specific material of the thermal insulation member 123.

[0053] In some embodiments, as Figure 4 and Figure 5 As shown, the shape of the heat exchange element 121 can be set to be cylindrical, and the material of the heat insulation element 123 can be ceramic glue; the heating element 122 can be attached to the outer wall of the heat exchange element 121, and the heat exchange element 121 can be sintered to the inner wall of the accommodating portion 112 through the heat insulation element 123.

[0054] For example, the heating element 122 can be configured as a heating net or heating wire, and the heating element 122 can be attached to the outer wall of the heat exchange element 121, so that the heat exchange element 121 can quickly and evenly heat the pressurized airflow, thereby improving the efficiency of atomization. In other embodiments, the heating element 122 can also be partially connected to the heat exchange element 121, so that the heat of the heating element 122 is transferred to the heat exchange element 121. This application does not impose any special restrictions on whether the heating element 122 is attached to the heat exchange element 121.

[0055] The thermal insulation 123 uses ceramic adhesive to secure the heating element 122 to the outer wall of the heat exchange element 121 and allows the heat exchange element 121 to be sintered to the inner wall of the accommodating portion 112. The ceramic adhesive also provides insulation and sealing. The pins of the heating mesh or heating wire can pass through the ceramic adhesive and be electrically connected to the power supply assembly 2. The ceramic adhesive also seals the gap between the heat exchange element 121 and the accommodating portion 112, thereby allowing the entire airflow to flow into the heat exchange channel 1200.

[0056] When assembling the atomizer 100, the heating element 120 and the airway component 131 may be sintered and formed using ceramic glue, thereby sealing the heating element 120 and the airway component 131. In other embodiments, a sealing member such as a silicone ring or a rubber ring may also be provided between the heating element 120 and the airway component 131. This application does not impose any particular limitation on the sealing method between the heating element 120 and the airway component 131.

[0057] In some embodiments, as Figure 4 and Figure 5 As shown, the heat exchange element 121 may have multiple heat exchange channels 1200 ; the multiple heat exchange channels 1200 may be arranged at intervals along the axial direction of the heat exchange element 121 , and the multiple heat exchange channels 1200 communicate with the lumen 1110 and the outlet of the air pump assembly 130 .

[0058] The multiple heat exchange channels 1200 can divide the pressurized airflow into multiple streams, thereby increasing the contact area between the pressurized airflow and the heat exchange element 121, rapidly increasing the temperature of the pressurized airflow and improving atomization efficiency. The end of the airway element 131 facing the heat exchange channels 1200 can be configured as a trumpet-shaped airway 1310, allowing the pressurized airflow to be dispersed into the multiple heat exchange channels 1200. The multiple heat exchange channels 1200 arranged axially along the heat exchange element 121 can converge into the tubular lumen 1110 and be ejected from the atomization hole 1100.

[0059] In other embodiments, the heat exchange channel 1200 can also be set as a spiral channel or a serpentine channel, so as to extend the time that the pressurized airflow flows in the heat exchange channel 1200. This application does not impose any special restrictions on the specific shape of the heat exchange channel 1200.

[0060] In some embodiments, as Figure 6 As shown, the atomization tube 111 may include a connected spike portion 1111 and a tube wall 1112; the tube wall 1112 is connected to the accommodating portion 112, and a plurality of atomization holes 1100 are arranged at intervals on the tube wall 1112, and the spike portion 1111 is arranged at one end of the tube wall 1112 away from the accommodating portion 112, and the spike portion 1111 is used to penetrate into the aerosol product 3.

[0061] The provision of the spike portion 1111 can reduce resistance when the atomizing tube 111 is inserted into the aerosol product 3, thereby facilitating insertion of the aerosol product 3 by the user. The multiple atomizing holes 1100 can increase the flow rate of the high-pressure hot air flow, thereby more fully atomizing the aerosol product 3. The multiple atomizing holes 1100 can be arranged at different locations along the axial and circumferential directions of the tube wall 1112, allowing the high-pressure hot air flow to penetrate into the aerosol product 3 from different directions.

[0062] In some embodiments, as Figure 2 and Figure 3 As shown, the shell 1 may include an outer shell 11 and a product container 12; the product container 12 is connected to the outer shell 11, one end of the product container 12 has an insertion port for inserting the aerosol product 3, the atomizer 100 is connected to the other end of the product container 12, and the atomizer 110 and the heating component 120 are arranged in the product container 12.

[0063] The atomizer 110 and heating element 120 are placed within the product container 12, allowing the product container 12 to provide insulation and heat insulation for the atomized aerosol product 3, thereby reducing heat loss. In some embodiments, the airway member 131 can be connected to the bottom of the product container 12, forming a container with an insertion port at one end. This allows the residue produced by the atomization of the aerosol product 3 to fall into the product container 12, making it easier for the user to clean the residue after use. This application does not impose any specific restrictions on the specific structure of the product container 12.

[0064] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
