Description

Technical Field

[0001] This application relates to the field of aerosol atomization technology, specifically to an atomizer and atomization device. Background Technology

[0002] Electronic atomizing devices are used to heat an aerosol matrix to generate aerosols. In existing technologies, electronic atomizing devices typically store the aerosol matrix. After prolonged use, the seals inside the device used to seal the aerosol matrix may fail. If the seals fail, the aerosol matrix can easily leak inside the device and flow through the air passages to the airflow sensor, causing the sensor to malfunction or be damaged. This leads to problems such as poor device operation and affects the device's lifespan. Utility Model Content

[0003] This application provides an atomizer and atomizing device, which aims to solve the technical problem of aerosol matrix leakage and damage to the airflow sensor caused by seal failure in electronic atomizing devices.

[0004] Some embodiments of this application provide an atomizer, including:

[0005] Atomizing core assembly, used to heat the aerosol matrix to atomize and generate aerosol;

[0006] An airflow sensor is used to sense negative pressure airflow to activate the atomizing core assembly; and,

[0007] The bracket is provided with a first mounting part, a first air passage and a second air passage. The atomizing core assembly is mounted on the first mounting part. The first air passage and the second air passage are separated on the bracket. The first air passage is used to guide external air into the atomizing core assembly, and the second air passage is used to guide the negative pressure airflow to act on the airflow sensor.

[0008] The first port of the first airway and the first port of the second airway are both located on the first mounting part, and the first port of the second airway is higher than the first port of the first airway.

[0009] In some embodiments, the support frame is further provided with columns;

[0010] The first port of the first air passage is disposed on the surface of the first mounting part, the column is connected to the surface of the first mounting part, the second air passage passes through the column, and the first port of the second air passage is disposed on the top of the column.

[0011] In some embodiments, the atomizer also has an air outlet;

[0012] The aerosol generated after atomization by the atomizing core component flows out through the air outlet, and the top of the column extends towards the air outlet.

[0013] In some embodiments, the bracket further includes a second mounting portion;

[0014] The first mounting part is disposed on the top of the bracket, the second mounting part is disposed on the side wall of the bracket, the airflow sensor is mounted on the second mounting part, and the second port of the second air passage is disposed on the second mounting part.

[0015] In some embodiments, the atomizer further includes a sealing plug;

[0016] The sealing plug is sealed between the airflow sensor and the second mounting part, and the sealing plug has a through hole communicating with the second air passage. The second air passage guides the negative pressure airflow to act on the airflow sensor through the through hole.

[0017] A receiving cavity is formed between the sealing plug and the second mounting part, and the second port of the second air passage is disposed in the receiving cavity.

[0018] In some embodiments, the first port of the second airway is located at the top of the bracket, the second port of the second airway is located on the side wall of the bracket, and at least one bend is provided in the path of the second airway.

[0019] In some embodiments, the bracket includes a package and a bracket body;

[0020] The bracket body is provided with a bent groove to form the bent section. The encapsulation is connected to the bracket body so that the encapsulation and the groove enclose to form the second air passage. The first air passage is provided on the bracket body.

[0021] In some embodiments, the atomizer further includes an inner shell and a sealing assembly;

[0022] The sealing assembly is connected to the inner shell and encloses it to form a liquid storage cavity, which is used to store the aerosol matrix and guide the aerosol matrix into the atomizing core assembly.

[0023] Some embodiments of this application also provide an atomizing device, including:

[0024] The atomizer described in any of the above embodiments;

[0025] A power supply component, electrically connected to the atomizer, is used to supply power to the atomizer; and,

[0026] The housing contains both the atomizer and the power supply assembly.

[0027] In some embodiments, the housing is provided with an air inlet, the second port of the first air passage in the atomizer is connected to the air inlet, and the first air passage is separated from the power supply component.

[0028] According to the atomizer in the above embodiments, by separately arranging the first and second air channels on the bracket, the first air channel can independently supply external air to the atomizing core assembly for atomization, and the second air channel can independently supply negative pressure airflow to the airflow sensor to activate the airflow sensor. The first and second air channels are isolated from each other, so even if the aerosol matrix leaks into the first air channel, it does not necessarily cause the leaked aerosol matrix to flow into the second air channel. Simultaneously, the first ports of both the first and second air channels are located at the first mounting portion, so that aerosol matrix leakage first occurs at the first mounting portion. However, because the first port of the second air channel is higher than the first port of the first air channel, it is less likely for the aerosol matrix to flow into the second air channel, thereby preventing the leaked aerosol matrix from contacting the airflow sensor. This improves the leak-proof performance of the atomizer and extends the service life of the atomizing device. Attached Figure Description

[0040] The present application will be further described in detail below with reference to specific embodiments and accompanying drawings. Similar elements in different embodiments are referred to by associated similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0041] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0042] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0043] In existing technologies, electronic atomizing devices typically use sealing silicone to isolate the aerosol matrix. When the sealing silicone fails or is damaged, the aerosol matrix can easily leak from the atomizer core within the electronic atomizing device. Since the atomizer core is usually connected to the air intake channel that provides the air needed for atomization, and this air intake channel also has a negative pressure channel for activating the airflow sensor, leaking aerosol matrix can easily flow directly from the air intake channel through the negative pressure channel to the airflow sensor. This can cause malfunctions such as the electronic atomizing device malfunctioning or failing to start, thus affecting the normal lifespan of the electronic atomizing device.

[0044] This application provides an atomizing device, such as... Figures 1 to 3 As shown, the atomizing device may include an atomizer 1, a power supply component 2, and a housing 3. The atomizer 1 can be used to heat the aerosol matrix and atomize it to generate an aerosol. The power supply component 2 is electrically connected to the atomizer 1 and is used to supply power to the atomizer 1. The atomizer 1 and the power supply component 2 can be installed in the same housing 3, thereby allowing the atomizer 1 and the power supply component 2 to be assembled to form a disposable atomizing device with a non-replaceable atomizer 1. Alternatively, the atomizer 1 and the power supply component 2 can also be installed in different housings 3, thereby allowing the atomizer 1 and the power supply component 2 to be assembled to form an atomizing device with a replaceable atomizer 1. Different housings 3 can be detachably connected by means of snap-fit, screw-fit, or magnetic attraction. This application does not impose any special restrictions on whether the atomizer 1 of the atomizing device is replaceable.

[0045] Among them, such as Figures 1 to 3 As shown, the overall shape of the atomizing device can be configured as a box-shaped structure with width, thickness, and height directions. For ease of description, the following embodiments will use the X direction as the width direction, the Y direction as the thickness direction, and the Z direction as the height direction for illustrative purposes. Of course, the overall shape of the atomizing device is not limited to a box shape; it can also be cylindrical or other shapes. This application does not impose any special limitations on the overall shape of the atomizing device.

[0046] To improve the leak-proof performance of the atomizer 1, this application also provides an atomizer 1, such as... Figures 2 to 6As shown, the atomizer 1 may include an atomizing core assembly 11, an airflow sensor 12, and a bracket 13. The atomizing core assembly 11 is used to heat the aerosol matrix to atomize and generate an aerosol. The airflow sensor 12 is used to sense negative pressure airflow to activate the atomizing core assembly 11. The bracket 13 is provided with a first mounting portion 131, a first air passage 133, and a second air passage 134. The atomizing core assembly 11 is mounted on the first mounting portion 131. The first air passage 133 and the second air passage 134 are separately disposed on the bracket 13. The first air passage 133 is used to guide external air into the atomizing core assembly 11, and the second air passage 134 is used to guide negative pressure airflow to act on the airflow sensor 12. The first port D11 of the first air passage 133 and the first port D21 of the second air passage are both located on the first mounting portion 131, and the first port D21 of the second air passage is higher than the first port D11 of the first air passage.

[0047] This application separates the first airway 133 and the second airway 134 on the bracket 13, allowing the first airway 133 to independently supply external air to the atomizing core assembly 11 for atomization, and the second airway 134 to independently supply negative pressure airflow to the airflow sensor 12 to activate it. The isolation between the first and second airways ensures that even if the aerosol matrix leaks into the first airway 133, it does not necessarily flow into the second airway 134. Simultaneously, both the first port D11 of the first airway 133 and the first port D21 of the second airway are located at the first mounting portion 131, ensuring that aerosol matrix leakage first occurs at the first mounting portion 131. However, since the first port D21 of the second airway is higher than the first port D11 of the first airway, the aerosol matrix is ​​less likely to flow into the second airway 134, thus preventing the leaked aerosol matrix from contacting the airflow sensor 12. This improves the leak-proof performance of the atomizer 1 and extends the service life of the atomizing device.

[0048] Understandably, during normal use of the atomizing device, the aerosol matrix flows downwards in the Z-direction. The fact that the first port D21 of the second airway is higher than the first port D11 of the first airway means that, in the opposite direction of the downward flow of the aerosol matrix, the first port D21 of the second airway is located above the first port D11 of the first airway in the Z-direction. When the aerosol matrix converges at the first port D11 of the first airway, because the first port D21 of the second airway is higher than the first port D11 of the first airway, the aerosol matrix is ​​less likely to flow into the second airway 134, thus preventing contact between the aerosol matrix and the airflow sensor 12.

[0049] The atomizing core assembly 11 may include a porous ceramic liquid guide and a heating element. The heating element may be integrally formed with the porous ceramic liquid guide in the shape of a heating mesh or heating wire. The porous ceramic liquid guide can adsorb the aerosol matrix for heating by the heating element. Alternatively, the atomizing core assembly 11 may also include an atomizing cover, a liquid guide, and a heating element. The heating element may be a heating mesh or heating wire fitted inside the liquid guide. The liquid guide is installed inside the atomizing cover, and the atomizing cover may have liquid guide holes so that the liquid guide can adsorb the aerosol matrix for heating by the heating element.

[0050] The power supply component 2 may include a battery cell 21 and a circuit board 22. The circuit board 22 is electrically connected to both the battery cell 21 and the heating element (or heating source), allowing the battery cell 21 to supply power to the atomizing core assembly 11 via the circuit board 22. An airflow sensor 12 may be electrically connected to the circuit board 22. Furthermore, the circuit board 22 may also be electrically connected to electronic devices such as a controller and a charging interface. The controller can be used to control the heating power of the atomizing core assembly 11, and the charging interface can be used to charge the battery cell 21. Depending on the different functional designs of the atomizing device, this application does not impose special limitations on the specific structure of the atomizing core assembly 11 and the power supply component 2.

[0051] In some embodiments, such as Figure 3 As shown, the bracket 13 may also be provided with a column 135; the first port D11 of the first air passage is provided on the surface of the first mounting part 131, the column 135 is connected to the surface of the first mounting part 131, the second air passage 134 passes through the column 135, and the first port D21 of the second air passage is provided on the top of the column 135.

[0052] For example, the first mounting part 131 can be configured as a groove, and the atomizing core assembly 11 can be installed in the groove. The first port D11 of the first air passage can be located at the bottom of the groove, allowing external air to flow into the atomizing core assembly 11 from the first port D11 of the first air passage for atomization. The column 135 is arranged along the Z direction, with its bottom connected to the bottom of the groove and its top higher than the bottom of the groove. By setting the first port D21 of the second air passage at the top of the column 135, the first port D21 of the second air passage can be suspended in the groove, thereby preventing a portion of the aerosol matrix from flowing downward along the groove wall into the second air passage 134, thus improving the leak-proof performance of the atomizer 1. Of course, in other embodiments, when the downward flow path of the aerosol matrix does not pass through the groove wall on one side, the first port D21 of the second air passage can also be located on the groove wall on that side, so that the first port D21 of the second air passage is higher than the first port D11 of the first air passage.

[0053] Depending on the shape of the inner support 13 of the atomizer 1, the first mounting part 131 can also be configured as a planar structure, on which the atomizing core assembly 11 can be mounted. The first port D11 of the first air passage can be located on this plane, and the bottom of the column 135 can be connected to this plane. Similarly, the first port D21 of the second air passage can be higher than the first port D11 of the first air passage. This application does not impose any special restrictions on the specific structure of the first mounting part 131.

[0054] In some embodiments, such as Figure 4 As shown, the atomizer 1 also has an air outlet 136; the aerosol generated after the atomizing core assembly 11 is atomized flows out through the air outlet 136, and the top of the column 135 extends towards the air outlet 136.

[0055] The air outlet 136 can be the mouthpiece on the atomizer 1, or it can be an atomizing tube connected to the mouthpiece. This application does not impose any special restrictions on the specific structure of the air outlet 136. When a user uses the atomizing device, such as... Figure 4 As shown, airflow exits from outlet 136, creating a negative pressure at outlet 136. Airflow within the second airway 134 flows in the direction indicated by the solid arrow in the figure, thus creating a negative pressure environment within the second airway 134. The top of the column 135 is extended closer to outlet 136, allowing the first port D21 of the second airway to be closer to outlet 136, i.e., closer to the negative pressure source. This allows the negative pressure airflow within the second airway 134 to more sensitively activate the airflow sensor 12. Upon sensing the negative pressure airflow within the second airway 134, the airflow sensor 12 can quickly activate the atomizing core assembly 11 via circuit board 22, thereby rapidly atomizing the aerosol matrix. The atomized aerosol flows out through outlet 136 in the direction indicated by the hollow arrow in the figure for user use.

[0056] In some embodiments, such as Figure 5 and Figure 6 As shown, the bracket 13 may also have a second mounting part 132; the first mounting part 131 is disposed on the top of the bracket 13, the second mounting part 132 is disposed on the side wall of the bracket 13, the airflow sensor 12 is mounted on the second mounting part 132, and the second port D22 of the second air passage is disposed on the second mounting part 132.

[0057] For example, the second mounting portion 132 can be configured as a groove, and the airflow sensor 12 can be installed inside the groove. The second port D22 of the second air passage can be located on the groove wall or bottom. When a negative pressure airflow is formed in the second air passage 134, the airflow sensor 12 can sense the negative pressure at the second port D22 of the second air passage within the groove, thereby activating the airflow sensor 12. Furthermore, by mounting the airflow sensor 12 on the second mounting portion 132, since the second mounting portion 132 is located on the side wall of the bracket 13, the airflow sensor 12 can be moved away from the atomizing core assembly 11, thereby increasing the distance between the airflow sensor 12 and the atomizing core assembly 11, and reducing the possibility of the aerosol matrix flowing directly to the airflow sensor 12.

[0058] In other embodiments, the second mounting portion 132 may also be configured as a through hole, which is directly connected to the second port D22 of the second air passage. The airflow sensor 12 is installed in the through hole, thereby activating the airflow sensor 12 by sensing the negative pressure airflow in the second air passage 134. This application does not impose any special restrictions on the specific structure of the second mounting portion 132.

[0059] In some embodiments, such as Figure 2 , Figure 5 and Figure 6 As shown, the atomizer 1 may also include a sealing plug 14; the sealing plug 14 is sealed between the airflow sensor 12 and the second mounting part 132, and the sealing plug 14 has a through hole communicating with the second air passage 134, through which the second air passage 134 guides negative pressure airflow to act on the airflow sensor 12; wherein, a receiving cavity 137 is formed between the sealing plug 14 and the second mounting part 132, and the second port D22 of the second air passage is disposed in the receiving cavity 137.

[0060] When the sealing plug 14 is inserted into the groove of the second mounting portion 132, the side of the sealing plug 14 facing the bottom of the groove does not contact the bottom of the groove, thus forming a receiving cavity 137 between the sealing plug 14 and the bottom of the groove. When a small portion of the aerosol matrix flows along the second air passage 134 to the airflow sensor 12, the receiving cavity 137 can store the leaked aerosol matrix, thereby preventing the leaked aerosol matrix from flowing directly to the airflow sensor 12, thus enhancing the leak-proof performance of the bracket 13. The working surface of the airflow sensor 12 is connected to the second port D22 of the second air passage through the through hole on the sealing plug 14, allowing the airflow sensor 12 to sensitively sense the negative pressure airflow within the second air passage 134. Therefore, the sealing plug 14 not only seals the gap between the airflow sensor 12 and the second mounting portion 132, but also forms a receiving cavity 137 between the sealing plug 14 and the second mounting portion 132 to prevent the leaked aerosol matrix from flowing directly to the airflow sensor 12.

[0061] In other embodiments, the groove of the second mounting portion 132 can also be configured as a stepped groove structure. When the sealing plug 14 is inserted into the groove of the second mounting portion 132, the side of the sealing plug 14 facing the bottom of the groove contacts the stepped bottom of the groove, and the part not in contact with the sealing plug 14 forms a receiving cavity 137 between the sealing plug 14 and the sealing plug 14, which can also prevent the leaked aerosol matrix from flowing directly to the airflow sensor 12. This application does not impose any special restrictions on the specific structure of the receiving cavity 137.

[0062] In some embodiments, such as Figure 7 As shown, the first port D21 of the second airway is located on the top of the bracket 13, the second port D22 of the second airway is located on the side wall of the bracket 13, and at least one bend 1340 is provided on the path of the second airway 134.

[0063] For example, a portion of the second airway 134 can be configured as a horizontal segment along the X direction on the support 13. One end of the horizontal segment can connect to the column 135 configured in the Z direction, forming a bend 1340; the other end of the horizontal segment can connect to the vertical segment configured in the Z direction, forming a bend 1340; this vertical segment then connects to the second port D22 of the second airway configured in the Y direction, forming a bend 1340. In this way, the path of the second airway 134 can form bends 1340 in all three directions (X, Y, and Z). Multiple bends 1340 can create a labyrinthine channel in the second airway 134, thereby extending the leakage path of the aerosol matrix and reducing the flow rate of the aerosol matrix to the airflow sensor 12. Furthermore, since the airflow within the second airway 134 is a negative pressure airflow, it can also slow down the flow rate of the aerosol matrix towards the airflow sensor 12.

[0064] In other embodiments, the second airway 134 may also have a greater number of bends 1340. For example, the horizontal segments of the second airway 134 may be configured as wavy or zigzag structures. Alternatively, the horizontal segments of the second airway 134 may also be bent in the Y direction. This application does not impose any special limitations on the specific shape of the second airway 134 or the specific number of bends 1340.

[0065] In some embodiments, such as Figure 8 As shown, the bracket 13 may include a package 13b and a bracket body 13a; the bracket body 13a is provided with a bent wire groove to form a bent section 1340, the package 13b is connected to the bracket body 13a so that the package 13b and the wire groove enclose to form a second air passage 134, and a first air passage 133 is provided on the bracket body 13a.

[0066] Since the second airway 134 has multiple bent segments 1340 formed on the bracket 13, in order to reduce the difficulty of processing the bent segments 1340 on the bracket 13, this application uses a bent groove on the bracket body 13a. This allows the bent segments 1340 to be processed into a semi-open groove structure by etching, stamping, injection molding, etc., to first process the second airway 134. Then, the encapsulation 13b is connected to the bracket body 13a by pasting or hot pressing, so that the encapsulation 13b and the groove structure enclose the second airway 134 with multiple bent segments 1340, thus reducing the difficulty of processing the second airway 134 on the bracket 13. Furthermore, when the atomizing device has been used for a long time and the user needs to clean the leaked aerosol matrix inside the second airway 134, they only need to remove the encapsulation 13b to clean the leaked aerosol matrix, making the operation simple.

[0067] In other embodiments, the bracket 13 can also be formed into a second airway 134 with multiple bent segments 1340 by 3D printing. However, compared to 3D printing, the structure in which the encapsulation component 13b is connected to the bracket body 13a can save on the manufacturing cost of the bracket 13. The encapsulation component 13b can be a sheet structure made of materials such as plastic or silicone to ensure the sealing performance of the second airway 134 after the encapsulation component 13b is connected to the bracket body 13a. This application does not impose any special limitations on the forming method of the second airway 134 or the material of the encapsulation component 13b.

[0068] In some embodiments, such as Figure 2 and Figure 5 As shown, the atomizer 1 may also include an inner shell 32 and a sealing assembly 15; the sealing assembly 15 is connected to the inner shell 32 and encloses it to form a liquid storage chamber 16, which is used to store the aerosol matrix and guide the aerosol matrix into the atomizing core assembly 11.

[0069] For example, the sealing assembly 15 may include a seal 151 and a support 152. The support 152 is mounted on the bracket 13 to support the seal 151 and the atomizing core assembly 11. The seal 151 is sealed within the inner shell 32 and forms a liquid storage chamber 16 with the inner shell 32. Simultaneously, drainage channels may be provided on the seal 151 and the support 152 to guide the aerosol matrix in the liquid storage chamber 16 towards the atomizing core assembly 11, thereby preventing the aerosol matrix from flowing into the second air passage 134 and reducing the risk of aerosol matrix leakage. The drainage channel may be a ramp sloping towards the atomizing core assembly 11, or it may be a pipe extending towards the atomizing core assembly 11. This application does not impose any special limitations on the specific shapes of the seal 151 and the support 152.

[0070] In some embodiments, such as Figure 2 and Figure 5As shown, the housing 3 is provided with an air inlet 30, the second port D12 of the first air passage in the atomizer 1 is connected to the air inlet 30, and the first air passage 133 is separated from the power supply component 2.

[0071] For example, the housing 3 may include an outer shell 31 and a bottom cover 33. An air inlet 30 may be located on the bottom cover 33. The bottom cover 33 can be detachably connected to the outer shell 31 via snap-fit, screw-fit, or magnetic attachment. The atomizer 1 and the power supply assembly 2 are both installed inside the housing 31. Wherein, for example... Figure 5 As shown, the first air passage 133 can be configured as a channel isolated from the battery cell 21 and the circuit board 22. External air flows through the air inlet 30 along the first air passage 133 to the atomizing core assembly 11 for atomization. When the aerosol matrix leaks from the first port D11 of the first air passage, the first air passage 133 can guide the leaked aerosol matrix to flow out from the air inlet 30, thereby preventing the aerosol matrix from leaking onto the battery cell 21 and / or the circuit board 22 and causing damage to the atomizing device.

[0072] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
