[0023] 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).
[0024] Example 1
[0025] This embodiment provides an atomizer 100. Please refer to [reference needed]. Figures 1-4The atomizer 100 includes a first housing 110, a second housing 120, and an atomizing core 130.
[0026] Please refer to Figures 2-3 The first housing 110 is provided with a nozzle 111, which has a first air outlet 112 and a second air outlet 113. The second housing 120 is located on the side of the first housing 110 away from the nozzle 111 and is detachably connected to the first housing 110. The second housing 120 has a liquid storage chamber 121 and an atomizing chamber 122 that are connected, and a first airflow sensing channel 123 isolated from the liquid storage chamber 121 and the atomizing chamber 122. The liquid storage chamber 121 and the first airflow sensing channel 123 are spaced apart along a first direction perpendicular to the height direction of the atomizer 100. The atomizing chamber 122 is connected to the first air outlet 112. One end of the first airflow sensing channel 123 is connected to the second air outlet 113, and the other end is connected to an airflow sensor (not shown). The atomizing core 130 is disposed in the atomizing chamber 122 and is used to atomize the atomizing matrix entering the atomizing chamber 122.
[0027] In this application, by making the first housing 110, which is provided with a nozzle 111, and the second housing 120, which is provided with a liquid storage chamber 121, an atomizing chamber 122, and a first airflow sensing channel 123, detachable, the manufacturing difficulty of the atomizer 100 can be reduced. Furthermore, the first airflow sensing channel 123 is isolated from the liquid storage chamber 121 and the atomizing chamber 122, with one end connected to the second air outlet 113 and the other end connected to the airflow sensor. The atomizing chamber 122 is connected to the second air outlet 113. This prevents the aerosol condensate in the first air outlet 112 and the atomizing chamber 122 from flowing onto the airflow sensor, thus extending the service life of the airflow sensor.
[0028] Please refer to Figures 2-3 The first housing 110 further defines a condensing chamber 114, within which a sealing assembly 140 is disposed. The sealing assembly 140 is spaced apart by a second airflow sensing channel 141 and a recess. The two ends of the second airflow sensing channel 141 are connected to a second air outlet 113 and a first airflow sensing channel 123, respectively. The recess and the inner wall of the condensing chamber 114 define a condensing space 142, within which a condensing element 150 is disposed. The condensing element 150 and the sealing assembly 140 define an atomizing channel 160, with the two ends of the atomizing channel 160 connected to the first air outlet 112 and the atomizing chamber 122, respectively.
[0029] In this application, the sealing assembly 140 seals the connection between the atomizing chamber 122 and the first air outlet 112. The sealing assembly 140 and the inner wall of the first housing 110 define a condensation space 142 where a condenser 150 is provided. The condenser 150 absorbs the condensate flowing back from the atomizing airway 160 and the first air outlet 112. Furthermore, the sealing assembly 140 also includes a second airflow sensing airway 141, which is independent of the atomizing airway 160. Therefore, the entire airflow sensing element of the atomizer 100 is independent of the airway paths of the atomizing airway 160, the atomizing chamber 122, and the first air outlet 112, thus minimizing the possibility of condensate flowing back from the first air outlet 112 and the atomizing chamber 122 onto the airflow sensing element.
[0030] Please refer to Figure 2 The atomizing airway 160 is defined by a hollow airway steel tube.
[0031] Please refer to Figure 2 and Figure 4 The sealing assembly 140 includes a first seal 143 and a second seal 144. The first seal 143 is connected to the second seal 144, and the second seal 144 is disposed away from the nozzle 111 relative to the first seal 143. A portion of the first seal 143 is disposed at the connection between the nozzle 111 and the condensation chamber 114, for sealing the connection between the atomizing air passage 160 and the first air outlet 112, and between the second airflow sensing air passage 141 and the second air outlet 113. A portion of the second seal 144 extends from the condensation chamber 114 into the atomizing chamber 122, and the portion extending into the atomizing chamber 122 has an atomizing air passage opening, which seals the connection between the atomizing air passage 160 and the atomizing chamber 122.
[0032] In this application, the first seal 143 seals the connection between the atomizing air passage 160 and the first air outlet 112, and the second seal 144 seals the connection between the atomizing chamber 122 and the atomizing air passage 160, which can ensure normal suction function while preventing aerosol leakage. The first seal 143 seals the connection between the second airflow sensing air passage 141 and the second air outlet 113, which can ensure the response speed of the airflow sensor.
[0033] Please refer to Figure 2 The second airflow sensing channel 141 passes through the first seal 143 and the second seal 144. A portion of the periphery of the first seal 143 is recessed inward to form a first recessed space, and a portion of the periphery of the second seal 144 is recessed inward to form a second recessed space. The first recessed space and the second recessed space define a recessed portion.
[0034] The recessed portion is formed by the circumferential recesses of the first seal 143 and the second seal 144. The recessed portion, combined with the inner wall of the condensation chamber 114, defines the condensation space 142. This design simplifies the structure of the first seal 143 and the second seal 144, making them easy to disassemble and install, and also allows for full utilization of the space in the condensation chamber 114.
[0035] Please refer to Figure 2 The first airflow sensing channel 123 and the second airflow sensing channel 141 are located on the same straight line, and the straight line is parallel to the height direction of the atomizer 100.
[0036] Arranging the first airflow sensing channel 123 and the second airflow sensing channel 141 in a straight line can shorten the air path of the airflow sensing element and improve the response speed.
[0037] Please refer to Figure 2 The air inlet 1231 of the first airflow sensing channel and the air inlet 1411 of the second airflow sensing channel are offset. A buffer cavity 1232 is defined at one end of the first airflow sensing channel 123 near the second airflow sensing channel 141. Both ends of the buffer cavity 1232 are connected to the air inlets 1411 of the first and second airflow sensing channels, respectively. In this embodiment, an air inlet channel 1233 is protruding from the bottom wall of the buffer cavity 1232 and is connected to the air inlet 1231 of the first airflow sensing channel.
[0038] When a user is inhaling, water vapor or aerosol in their mouth will inevitably enter the second airflow sensing channel 141 and the first airflow sensing channel 123 from the second air outlet 113, and may eventually flow to the airflow sensor. Therefore, by staggering the air inlet 1231 of the first airflow sensing channel and the air inlet 1411 of the second airflow sensing channel, the condensate in the second airflow sensing channel 141 can be prevented from flowing directly from the air inlet 1411 of the second airflow sensing channel to the air inlet 1231 of the first airflow sensing channel, and then directly from the air inlet 1231 of the first airflow sensing channel to the airflow sensor. In addition, a buffer chamber 1232 is defined at one end of the first airflow sensing channel 123 near the second airflow sensing channel 141, so that the liquid flowing out of the air inlet 1411 of the second airflow sensing channel can be buffered in the buffer chamber 1232 first. Since the air inlet channel 1233 is provided on the bottom wall of the buffer chamber 1232, the time for the condensate to flow from the buffer chamber 1232 to the first airflow sensing channel 123 can be delayed.
[0039] Please refer to Figure 3The first housing 110 also has a mounting cavity 115, which communicates with the liquid storage cavity 121. A liquid storage container 170 is detachably mounted on the mounting cavity 115, and the liquid storage container 170 is used to replenish the atomizing matrix to the liquid storage cavity 121. In this application, a liquid storage element 173 is provided inside the liquid storage cavity 121, and the liquid storage element 173 stores the atomizing matrix.
[0040] By detachably installing the liquid storage container 170 in the mounting cavity 115, the atomizing matrix can be replenished to the liquid storage component 173. Furthermore, the liquid storage container 170 can be replaced, allowing for the recycling of other structures of the atomizer 100 besides the liquid storage container 170, thereby reducing operating costs.
[0041] Please refer to Figure 3 The container cap 171 of the oil storage container has a support step 172 for supporting the body of the oil storage container.
[0042] Please refer to Figure 3 The second seal 144 extends from the condensation chamber 114 to the space between the mounting chamber 115 and the liquid storage chamber 121, sealing the connection between the liquid storage container 170 and the liquid storage chamber 121, thus forming a liquid passage between them. The liquid storage container 170 can be installed upside down in the mounting chamber 115. The area around the liquid outlet at the lower end of the liquid storage container 170 can be press-fitted with the second seal 144, allowing the atomized matrix flowing out of the liquid outlet of the liquid storage container 170 to pass through the second seal 144 and flow into the liquid storage chamber 121.
[0043] The second seal 144 seals the connection between the liquid storage container 170 and the liquid storage chamber 121, which can prevent the leakage of the atomized matrix in the liquid storage container 170.
[0044] Please refer to Figures 3-4 The liquid storage container 173 is configured to enclose a hollow fixed steel tube 174. A push pin 175 is fixed inside the fixed steel tube 174. The push pin 175 is used to open the seal of the liquid outlet of the container cap 171 of the liquid storage container 170. Additionally, a tension spring is provided on the container cap 171, which is used to push the seal to close the liquid outlet. It should be noted that the liquid storage container 170 is prior art and will not be described in detail here.
[0045] Please refer to Figures 2-3 The atomizer 100 also includes a base 176, which is disposed at the end of the second housing 120 opposite to the first housing 110, and forms a docking cavity 180 with the second housing 120. The docking cavity 180 communicates with the atomizing cavity 122. A third sealing element 181 and a fourth sealing element 182 are provided on the base 176. The third sealing element 181 is provided with a first through hole, one end of which communicates with the first airflow sensing channel 123, and the other end of which communicates with the airflow sensing element. Figure 2The first through hole extends into one end of the air inlet 1231 of the first airflow sensing channel, ensuring the sensitivity of the airflow sensor. The fourth sealing element 182 is provided with a second through hole and a third through hole. One end of the second through hole communicates with the docking cavity 180, and the other end communicates with the outside. The pins of the atomizing core 130 extend into the docking cavity 180, and the third through hole allows the electrode post of the power supply device 210 to pass through for electrical connection with the pins.
[0046] By placing the third seal 181 and the fourth seal 182 on the base 176, the airtightness of the air passage of the airflow sensor, the airtightness of the docking chamber 180 and the atomizing chamber 122, and the reliability of the interference fit between the power supply device 210 and the atomizer 100 can be guaranteed.
