Description

Technical Field

[0001] This invention relates to the field of aerosol manufacturing technology, specifically to a main unit and an aerosol generating device. Background Technology

[0002] Currently, aerosol generating devices on the market generally consist of a main unit and an atomizer inserted into the main unit. The main unit is equipped with a main electrode, and the atomizer is equipped with an atomizing electrode. The main electrode and the atomizing electrode are electrically connected after contact, thus enabling the main unit to supply power to the atomizer. However, there are generally two types of atomizers: one type has a hollow atomizing electrode with an air inlet, while the other type does not have an air inlet on its atomizing electrode, but rather the air inlet is formed on the atomizer shell. However, in existing technology, one main unit can only be used with one type of atomizer, resulting in poor compatibility and an inability to effectively adapt to different types of atomizers. Summary of the Invention

[0003] This invention provides a host and an aerosol generating device to solve the technical problem that the host and aerosol generating device have poor compatibility and cannot be well adapted to different types of atomizers.

[0010] Optionally, the air intake chamber includes a detection chamber formed by the electrode bracket, the microphone is installed in the detection chamber, and the electrode bracket also forms a second microphone air passage. The first microphone air passage is connected to the detection chamber and the air intake chamber respectively, and the second microphone air passage is connected to the detection chamber and the air intake channel respectively.

[0011] Optionally, the housing includes an outer shell and a battery bracket, the battery bracket being mounted on the outer shell and forming the second receiving space.

[0012] Optionally, the housing has a first latch and part on the side near the receiving cavity, and the atomizer has a second latch and part that cooperates with the first latch and part.

[0013] The second technical solution adopted by the present invention is: providing an aerosol generating device, the aerosol generating device including an atomizer and a main unit as described above, the atomizer including an atomizing body and an atomizing electrode, the atomizing body being inserted into the receiving cavity and forming an atomizing channel, the atomizing electrode being installed on the atomizing body and electrically connected to the main unit electrode; wherein, the atomizing electrode forming a guide hole communicating with the atomizing channel, the main unit electrode being inserted into the guide hole, so that the electrode support is located in the first moving position; or the atomizing body forming an air inlet, the air inlet communicating with the atomizing channel and the receiving cavity respectively, the atomizing electrode pushing the main unit electrode, so that the electrode support moves to the second moving position.

[0014] The beneficial effects of this invention are as follows: By movably arranging the electrode holder within the first receiving space, and by forming an air intake channel on the electrode holder, the electrode holder has a first movement position and a second movement position when the main unit is matched with different atomizers, allowing outside air to flow into the atomizer in different ways. Therefore, this main unit has good compatibility and can be adapted to different types of atomizers. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] The present invention also provides an aerosol generating device, such as... Figure 3-6 As shown, Figure 3 This is a cross-sectional view of an aerosol generating device according to an embodiment of the present invention. Figure 4 This is a cross-sectional view of an aerosol generating device according to another embodiment of the present invention. Figure 5 yes Figure 3 A cross-sectional view of atomizer 1 in the middle. Figure 6 yes Figure 4 A cross-sectional view of the atomizer 1' in the diagram. This aerosol generating device includes a main unit 100 and an atomizer 1, which can be detachably installed on the main unit 100 via snap-fit, magnetic adsorption, or other methods. Figure 3 and Figure 5As shown, the atomizer 1 includes an atomizing body 11 and an atomizing electrode 12. The atomizing body 11 forms an atomizing channel 110, and the atomizing electrode 12 is mounted on the atomizing body 11 and forms a guide hole 120 communicating with the atomizing channel 110. The atomizing body 11 includes a liquid storage chamber 111, a base 112, and an atomizing core 113. The liquid storage chamber 111 forms a liquid storage cavity 1110 and an air outlet channel 1111. The base 112 is disposed within the liquid storage cavity 1110 and connected to one end of the liquid storage chamber 111, and the base 112 forms the atomizing channel 110. The atomizing core 113 is mounted on the base 112 and communicates with the liquid storage cavity 1110, the air outlet channel 1111, and the atomizing channel 110, respectively. The atomizing electrode 12 is mounted on the base 112 and electrically connected to the atomizing core 113. Figure 6 As shown, the atomizer 1' includes an atomizing body 11' and an atomizing electrode 12'. The atomizing body 11' has an atomizing channel 110' and an air inlet 111' that communicates with the atomizing channel 110'.

[0025] The main unit 100 includes a housing 2, an electrode bracket 3, and a main unit electrode 4. The electrode bracket 3 is movably installed inside the housing 2, and the main unit electrode 4 is installed on the electrode bracket 3 and forms an air intake channel 40.

[0026] For example, the housing 2 forms a first receiving space 20 and an air inlet 21 communicating with the first receiving space 20. The electrode holder 3 is movably disposed within the first receiving space 20 and divides the first receiving space 20 into a receiving cavity 20A and an air inlet cavity 20B. The receiving cavity 20A is used to insert the atomizer 1. The main electrode 4 is mounted on the electrode holder 3 and forms an air inlet channel 40, which communicates with the air inlet cavity 20B. The electrode holder 3 has a first movable position that connects the air inlet 21 with the air inlet cavity 20B and a second movable position that connects the air inlet 21 with the receiving cavity 20A. That is, when the main unit 100 is adapted to the atomizer 1, the main electrode 3 is inserted into the guide hole 120, so that the electrode holder 3 is located in the first movable position, and outside air flows into the atomization channel sequentially through the air inlet 21, the air inlet cavity 20B, and the air inlet channel 40. When the main unit 100 is paired with the atomizer 1', the atomizing electrode 12' blocks the air intake channel 40 and pushes the electrode support 3 downward, thereby placing the electrode support 3 in a second moving position. Outside air flows sequentially into the atomizing channel 110' through the air intake 21, the receiving cavity 20A, and the air intake hole 111'. By movably positioning the electrode support 3 within the first receiving space 20, and by forming the air intake channel 40 on the main unit electrode 4, the main unit 100 allows the electrode support 3 to have both a first and a second moving position when paired with the atomizer 1 or the atomizer 1', enabling outside air to flow into the atomizer 1 in different ways. Therefore, the main unit 100 has good compatibility and can be paired with different types of atomizers.

[0027] The housing 2 also forms a second receiving space 22. The main unit 100 also includes a power supply component 5, which is disposed within the second receiving space 22 and electrically connected to the main unit electrodes 4. For example, the housing 2 includes an outer shell 23 and a battery holder 24. The battery holder 24 is installed within the outer shell 23 and forms the second receiving space 22. During production and assembly, the power supply component 5 is first disposed within the second receiving space 22 and installed on the battery holder 24, and then the battery holder 24 is installed within the outer shell 23. This facilitates the assembly of the main unit 100, and the power supply component 5 has high stability after assembly.

[0028] The outer edge of the battery bracket 24 is provided with a first sealing element 241. The battery bracket 24 is sealed against the inner wall of the outer casing 23 through the first sealing element 241. This can prevent water and air from entering and increase the friction between the battery bracket 24 and the outer casing 23, making the battery bracket 24 more stable after being installed in the outer casing 23.

[0029] The electrode holder 3 is movably disposed within the first receiving space 20, dividing the first receiving space 20 into a receiving cavity 20A and an air inlet cavity 20B. The receiving cavity 20A is used to insert the atomizer 1. For example, after the battery holder 24 is installed inside the housing 23, the housing 23 and the battery holder 24 enclose the first receiving space 20. The housing 23 has an air inlet 21, which communicates with the first receiving space 20. An air inlet cavity 20B is formed between the electrode holder 3 and the battery holder 24. Furthermore, the outer edge of the electrode holder 3 is provided with a second sealing member 31, which seals against the inner wall of the housing 23. This prevents water ingress and air leakage, and also increases the friction between the electrode holder 3 and the housing 23, ensuring that the electrode holder 3 will not move without external force.

[0030] The main electrode 4 is mounted on the electrode bracket 3 and forms an air intake channel 40, which communicates with the air intake chamber 20B. For example, the electrode bracket 3 has a through hole 32, into which the main electrode 4 is inserted, with one side of the main electrode 4 located in the receiving cavity 20A and the other side located in the air intake chamber 20B. The main electrode 4 is hollow, thus forming the air intake channel 40, which can penetrate the main electrode 4 from top to bottom, thereby communicating with the air intake chamber 20B. Alternatively, the air intake channel 40 can extend from the upper end of the main electrode 4 to the position of the main electrode 4 corresponding to the air intake chamber 20B, and then a through hole 41 is formed on the main electrode 4, communicating with both the air intake chamber 20B and the air intake channel 40, thereby communicating with the air intake chamber 20B through the through hole 41. It should be noted that when the main unit 100 is matched with the atomizer 1, a hole can be made on the upper end face or side wall of the main unit electrode 4 so that the air intake channel 40 is connected to the atomization channel 110.

[0031] The power supply assembly 5 is disposed within the second receiving space 22 and electrically connected to the host electrode 4. Exemplarily, the power supply assembly 5 includes a battery 51 and a circuit board 52. The circuit board 52 is electrically connected to both the battery 51 and the host electrode 4.

[0032] The power assembly 5 may also include a charging tail plate 53, which is electrically connected to the battery 51. The charging tail plate 53 has a charging interface 531. The battery bracket 24 has a first mounting hole 242 corresponding to the position of the charging interface 531, and the housing 23 has a second mounting hole 231 corresponding to the position of the charging interface 531. The charging interface 531 is disposed within the first mounting hole 242 and the second mounting hole 231. Users can charge the battery 51 through the charging interface 531, allowing the main unit 100 to be reused and preventing resource waste.

[0033] The main unit 100 also includes a resilient return member 6, one end of which is connected to or abuts against the electrode holder 3, and the other end is connected to or abuts against the housing 2. For example, the electrode holder 3 has a mounting post 33, one end of the resilient return member 6 is mounted on and abuts against the mounting post 33, and the other end abuts against the battery holder 24. When the main unit 100 is matched with the atomizer 1', the atomizer 1' pushes the electrode holder 3 from a first moving position to a second moving position. When the atomizer 1' is separated from the main unit 100, the resilient return member 6 can push the electrode holder 3 from the second moving position back to the first moving position, that is, the resilient return member 6 can reset the moved electrode holder 3, allowing the main unit 100 to match the atomizer 1 or the atomizer 1' again. It is understood that the battery holder 24 may also be provided with a mounting portion, one end of the resilient return member 6 is mounted on and abuts against the mounting post 33, and the other end is mounted on and abuts against the mounting portion, thus making the resilient return member 6 more stable after installation.

[0034] It should be noted that the main unit 100 may also omit the elastic return element 6, instead providing a first magnetic element on the electrode holder 3, and a second magnetic element on the housing 2 at the position corresponding to the first magnetic element. The opposing end faces of the first and second magnetic elements have the same magnetism, generating a repulsive force. This allows the moved electrode holder 3 to reset, enabling the main unit 100 to reconnect with the atomizer 1 or atomizer 1'. For example, the electrode holder 3 is provided with the first magnetic element, and the battery holder 24 is provided with the second magnetic element at the position corresponding to the first magnetic element.

[0035] It is understandable that the host 100 may be equipped with a first magnetic component and a second magnetic component, while also having a flexible recovery component 6.

[0036] The housing 2 is provided with a first latching part on the side near the first receiving space 20, and the atomizer 1' is provided with a second latching part that cooperates with the first latching part. The housing 2 is snapped into place with the atomizer 1' through the mutual cooperation of the first latching part and the second latching part. For example, the outer shell 23 is provided with a first latching part on the side near the first receiving space 20, and the first latching part is located inside the first receiving space 20. The atomizer 1' is provided with a second latching part that cooperates with the first latching part. When the atomizer 1' is inserted into the receiving cavity 20A, the first latching part and the second latching part cooperate with each other to fix the atomizer 1' in the receiving cavity 20A. In this way, the electrode support 3 can be pushed downward, and when the first latching part and the second latching part cooperate with each other, the electrode support 3 and the atomizer 1' will no longer move under the restoring force of the elastic restoring member 6 or the first magnetic member and the second magnetic member.

[0037] It is understandable that the housing 2 may not have the first clip and part, and the atomizer 1' may not have the second clip and part. As long as the sum of the frictional forces between the atomizer 1' and the electrode holder 3 and the housing 2 is greater than the restoring force of the elastic restoring member 6 or the first magnetic member and the second magnetic member, the electrode holder 3 and the atomizer 1' will no longer move under the restoring force of the elastic restoring member 6 or the first magnetic member and the second magnetic member.

[0038] The main unit 100 also includes a microphone 7, which is electrically connected to the power supply assembly 5. For example, the microphone 7 is disposed within the air intake chamber 20B and electrically connected to the circuit board 52. The electrode holder 3 also forms a first microphone air passage 34, which communicates with both the receiving chamber 20A and the air intake chamber 20B. When the electrode holder 3 is in the first moving position, outside air flows sequentially into the atomization channel through the air intake port 21, the air intake chamber 20B, and the air intake channel 40. The microphone 7 can detect whether airflow is generated in the air intake chamber 20B. When the electrode holder 3 is in the second moving position, outside air flows sequentially into the atomization channel 110' through the air intake port 21, the receiving chamber 20A, and the air intake hole 111'. The microphone 7 can detect whether airflow is generated in the receiving chamber 20A through the first microphone air passage 34. Only when the microphone 7 detects airflow generated in the air intake chamber 20B or the receiving chamber 20A will the microphone 7 activate the battery 51, causing the main unit 100 to supply power to the atomizer 1.

[0039] It should be noted that the air intake chamber 20B may include a detection chamber 35 formed by the electrode holder 3. The microphone 7 is installed in the detection chamber 35. The first microphone air passage 34 is connected to both the receiving chamber 20A and the detection chamber 35, meaning that the microphone 7 detects whether airflow is generated in the receiving chamber 20A through the first microphone air passage 34. After the microphone 7 is installed in the detection chamber 35, the detection chamber 35 is not connected to the air intake chamber 20B. The electrode holder 3 also forms a second microphone air passage 36, which is connected to both the detection chamber 35 and the air intake channel 40, meaning that the microphone 7 detects whether airflow is generated in the air intake channel 40 through the second microphone air passage 36. When the electrode holder 3 is in the first moving position, the atomizer 1 blocks the first microphone air passage 34, and the microphone 7 can detect whether airflow is generated in the air intake channel 40 through the second microphone air passage 36. When the electrode holder 3 is in the second moving position, the atomizer 1' blocks the air intake channel 40, and the microphone 7 can detect whether airflow is generated in the receiving cavity 20A through the first microphone air passage 34. Only when the microphone 7 detects airflow generated in the receiving cavity 20A or the air intake channel 40 will the microphone 7 activate the battery 51, so that the host 100 supplies power to the atomizer 1.

[0040] Compared with related technologies, the host 100 provided in this application movably mounts the electrode holder 3 within the first receiving space 20, and the host electrode 4 forms an air intake channel 40. This allows the electrode holder 3 to have a first movement position and a second movement position when the host 100 is matched with the atomizer 1 or atomizer 1', thereby allowing outside air to flow into the atomizer 1 in different ways. Therefore, the host 100 has good compatibility and can be adapted to different types of atomizers.
