Description

Technical Field

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

[0002] Tobacco products (such as cigarettes, cigars, etc.) produce tobacco smoke by burning tobacco during use. Efforts are being made to replace these tobacco-burning products by creating products that release compounds without combustion.

[0003] Examples of such products are heating devices that release compounds by heating rather than burning materials. For example, the material could be tobacco or other non-tobacco products, which may or may not contain nicotine. As another example, aerosol-providing articles exist, such as so-called electronic atomizing devices. These devices typically contain a liquid that is heated to vaporize, thereby producing an inhalable aerosol. The liquid may contain nicotine and / or flavorings and / or aerosol-generating substances (e.g., glycerin). Known electronic atomizing devices replenish the liquid matrix to a reusable atomizer via a separately replaceable reservoir and pump the liquid matrix from the reservoir into the atomizer via a manually or electrically operated pump.

In embodiments, the housing is defined by a plurality of components, such as in Figures 1 to 5 In the case, the outer shell includes a first housing 10 and a second housing 141 located between the first housing 10 and the first end 110.

[0111] In one embodiment, the second housing 141 is arranged close to the second side 140 and defines the first end 110. The second housing 141 is spaced apart from the first side 130, and thus the second housing 141 of the outer shell protrudes relative to the first housing 10 at the first end 110.

[0112] according to Figures 1 to 5 As shown, the power supply unit 100 includes:

[0113] A bracket 142 is arranged near the second side 140 and is covered by the second housing 141. The bracket 142 is used to house and retain the drive mechanism 150.

[0115] The first receiving cavity 111 is arranged near the first side 130 and has an opening facing the first end 110. In use, the atomizer 200 can be received at least partially from the first end 110 into the first receiving cavity 111, thereby establishing a conductive connection with the power supply body 100.

[0116] In an embodiment, a first receiving cavity 111 is formed or defined between a support 142 and a first side 130. The surface of the support 142 facing the first side 130 is a longitudinally extending flat plane; thus, in use, when the atomizer 200 is received in the first receiving cavity 111, it can move against the surface of the support 142 facing the first side 130 toward the second end 120 to be guided by the surface of the support 142.

[0127] In one embodiment, the first air inlet 131 is arranged on the first side 130. In another embodiment, the size of the first air inlet 131 is adjustable. Specifically, the first air inlet 131 is provided with a blocking component that can be moved by the user, so that the area of ​​the first air inlet 131 blocked by the blocking component can be selectively adjusted by the user's movement operation, thereby adjusting the size of the first air inlet 131.

[0129] according to Figures 1 to 5 As shown, the power supply unit 100 also includes:

[0130] An air intake passage 132 extends from a first air inlet 131 to a first receiving chamber 111; when the atomizer 200 is received in the first receiving chamber 111, the air intake passage 132 provides a communication path for delivering air from the first air inlet 131 to the atomizer 200. Alternatively, when the atomizer 200 is received in the first receiving chamber 111, the atomizer 200 is in communication with the first air inlet 131 via the air intake passage 132. When the atomizer 200 is received in the first receiving chamber 111, the second air inlet 221 of the atomizer 200 is aligned with and communicates with the port of the air intake passage 132 located in the first receiving chamber 111.

[0131] according to Figure 3 and Figure 4 As shown, the air intake channel 132 is located at the port of the first receiving cavity 111 and is arranged basically off the central axis of the first receiving cavity 111.

Figure 7 In the illustrated embodiment, the extension length of the second tubular element 28 is greater than the extension length of the capillary element 27; thus, the second tubular element 28 is at least partially held by the capillary element 27. The second tubular element 28 has an upper end facing the proximal end 210 and a lower end facing the distal end 220; the lower end of the second tubular element 28 is inserted into the sealing base 25.

In this embodiment, the first valve 238 is directly surrounding and mounted on the first free end of the first pipe 234, thus ensuring stable installation.

[0182] In one embodiment, the first valve 238 is arranged to allow fluid to flow from the first port 231 through the first conduit 234 to the first reservoir 213 only. The first valve 238 is also arranged to prevent fluid from flowing from the first reservoir 213 through the first conduit 234 to the first port 231.

[0192] During use, when the atomizer 200 is removed from the power supply unit 100, the second valve 237 can prevent external air from entering the first liquid storage chamber 213 or prevent leakage. And when the atomizer 200 is not removed from the power supply unit 100, since the space of the second liquid storage chamber 411 is larger than that of the first liquid storage chamber 213, the second valve 237 can also prevent air expansion in the second liquid storage chamber 411 from entering the first liquid storage chamber 213 under changes in the external environment or testing conditions such as high temperatures, thus avoiding leakage.

In an embodiment, the first connector 521 of the fluid transfer mechanism 500 can compress or apply pressure to the first blocking portion 431, causing the first slit to open in response to an increase in pressure on the first blocking portion 431, allowing the first connector 521 to extend through the first blocking portion 431 into and communicate with the second reservoir 411. In this embodiment, when the reservoir 400 is independently removed or replaced from the electronic atomizing device, the first slit on the first blocking portion 431 contracts to form a self-sealing seal, thereby providing a barrier or seal between the first insertion port 421 and the second reservoir 411 to prevent the liquid matrix inside the second reservoir 411 from flowing out of the exposed first insertion port 421. Here, "self-sealing" is a mechanical term referring to the ability of an object to achieve a seal under certain conditions without the need for external auxiliary sealing devices.

In an embodiment, the second connector 522 of the fluid transfer mechanism 500 can compress or apply pressure to the second blocking portion 432, causing the second slit to open in response to an increase in pressure on the second blocking portion 432, thereby allowing the second connector 522 to extend through the second blocking portion 432 into and communicate with the second reservoir 411. In an embodiment, when the reservoir 400 is independently removed or replaced from the electronic atomizing device, the first slit on the second shielding portion 432 contracts to form a self-sealing mechanism, thereby providing shielding or sealing between the second insertion port 422 and the second reservoir 411 to prevent the liquid matrix inside the second reservoir 411 from flowing out from the exposed second insertion port 422.

In an embodiment, the third connector 523 of the fluid transfer mechanism 500 can compress or apply pressure to the third blocking portion 433, causing the third slit to open in response to the increased pressure on the third blocking portion 433, allowing the third connector 523 to extend through the third blocking portion 433 into and communicate with the second reservoir 411. In an embodiment, when the reservoir 400 is independently removed or replaced from the electronic atomizing device, the first slit on the third shielding portion 433 contracts to form a self-sealing mechanism, thereby providing shielding or sealing between the third insertion port 423 and the second reservoir chamber 411 to prevent the liquid matrix inside the second reservoir chamber 411 from flowing out from the exposed third insertion port 423.

Furthermore, the first connector 521, the second connector 522, and the third connector 523 are exposed in the second receiving cavity 122.

[0216] When the reservoir 400 is received in the second receiving cavity 122, the first connector 521 is inserted into the first connector 421 of the reservoir 400 and communicates with the second reservoir cavity 411, the second connector 522 is inserted into the second connector 422 of the reservoir 400 and communicates with the second reservoir cavity 411, and the third connector 523 is inserted into the third connector 423 of the reservoir 400 and communicates with the second reservoir cavity 411.

[0218] Connector 531 and connector 532. After assembly, the ports of connector 531 and connector 532 can be exposed on the bottom surface of the first receiving cavity 111.

[0230] In use, the first orientation of the electronic atomizing device in its upright position can be characterized by the user holding the electronic atomizing device with the first end 110 facing away from the ground.

[0257] In some embodiments, the flat flexible cable 146 may include at least one electrically insulating substrate layer and at least one or more conductors formed on the substrate layer. In some embodiments, the substrate layer is flexible, thereby making the flat flexible cable 146 flexible. In some embodiments, the substrate layer may include a polyimide film, a resin film, a surface-insulating metal film, etc. In some embodiments, the at least one or more conductors may include conductive lines printed, sprayed, or deposited on the substrate layer. Alternatively, in some other embodiments, the flat flexible cable 146 may include two electrically insulating substrate layers arranged laminated or stacked, with at least one or more conductors sandwiched between the two electrically insulating substrate layers.

[0258] In this embodiment, the flat flexible cable 146 may have a thickness of 0.05 mm to 3 mm.

[0259] In an embodiment, the flat flexible cable 146 may include at least one signal transmission wire for transmitting signals between the detection circuit board 145 and the main circuit board 114. Additionally, the flat flexible cable 146 may include at least one power transmission wire for transmitting power between the circuit board detection circuit board 145 and the main circuit board 114.

[0260] according to Figures 1 to 5 As shown, the flat flexible cable 146 is at least partially attached to or held against the surface of the bracket 142 facing the first side 130. This is advantageous for the secure installation of the flat flexible cable 146.

[0261] In some embodiments, the first pump 151 and / or the second pump 152 can be electrically connected to the main circuit board 114 via a flat flexible cable 146. This allows the main circuit board 114 to control the activation of the first pump 151 and / or the second pump 152.

[0262] according to Figures 1 to 5As shown, the power supply unit 200 also includes:

[0263] The indicator element 144 is at least partially exposed outside the second housing 141. Alternatively, the indicator element 144 passes through the second housing 141 and is exposed outside the first end 210.

[0264] In use, the indicator element 144 is electrically connected to the main circuit board 114 via a flat flexible cable 146; the main circuit board 114 can then control the indicator element 144 to provide the user with visual or tactile prompts related to the use of the electronic atomizing device. In some embodiments, the indicator element 144 may include a flashlight, a display screen, a vibration motor, or a buzzer, etc.

[0265] For example, when the first pump 151 and / or the second pump 152 are starting up, the main circuit board 114 can control the indicator element 144 to generate a first indication, such as a visual or tactile one, to inform the user that the first pump 151 and / or the second pump 152 are starting up. For example, in some embodiments, the first indication is a light signal indication. And, the first indication is continuous. In a more specific embodiment, the first indication is a continuous green light to indicate to the user that the first pump 151 and / or the second pump 152 are starting up normally.

[0266] For example, when the first pump 151 and / or the second pump 152 malfunctions or malfunctions, the main circuit board 114 can control the indicator element 144 to generate a second indication, such as a visual or tactile one, to inform the user that the first pump 151 and / or the second pump 152 has malfunctioned or malfunctioned. For example, in some embodiments, the second indication is a light signal indication. And, the second indication is continuous. In a more specific embodiment, the second indication is a continuous red light to alert the user when the first pump 151 and / or the second pump 152 has malfunctioned or malfunctioned.

[0267] For example, when the liquid matrix in the second reservoir 411 is completely replenished into the first reservoir 213, and thus the liquid matrix in the second reservoir 411 is completely consumed, the main circuit board 114 can control the indicator element 144 to generate a third indication, such as a visual or tactile one, to inform the user to replace the reservoir 400. For example, in some embodiments, the third indication is a light signal. And, the second indication is intermittent. In a more specific embodiment, the third indication is an intermittently flashing yellow light to prompt the user to replace the reservoir 400.

[0268] In use, the user operates the input element 143 to drive the first pump 151 and the second pump 152 to pump the liquid matrix and air between the first liquid storage chamber 213 and the second liquid storage chamber 411. (See [link to relevant documentation]). Figures 19 to 21 As shown, it includes:

[0269] S10, according to Figure 19As indicated by the middle arrow R41, the first pump 151 starts working and pumps the liquid matrix in the second liquid storage chamber 411 to the first liquid storage chamber 213 via the first fluid channel. Specifically, the liquid matrix in the second liquid storage chamber 411 enters from the liquid output pipe 441, and then, driven by the first pump 151, passes through the second connector 522, the connecting channel 543, the first pump 151, the connecting channel 544, the connector 532, the first pipe 234, and the first valve 238 in sequence before being pumped into the first liquid storage chamber 213.

[0270] S20, according to Figure 20 As indicated by arrow R42, when the first pump 151 pumps the liquid matrix from the second storage chamber 411 into the first storage chamber 213, the second pump 152 can start working almost simultaneously, thereby drawing air from the first storage chamber 213 into the second storage chamber 411 via the second fluid channel. Specifically, the air in the first storage chamber 213 enters through the second free end of the second pipe 233, and then sequentially passes through the second valve 237, connector 531, connecting channel 542, second pump 152, connecting channel 541, and first plug 521 before entering the second storage chamber 411. In use, the first pump 151 and the second pump 152 can start working almost simultaneously, so that when the liquid matrix is ​​pumped from the second storage chamber 411 into the first storage chamber 213, air can be drawn from the first storage chamber 213 into the second storage chamber 411, maintaining pressure balance between the first storage chamber 213 and the second storage chamber 411.

[0271] In use, the load of the first pump 151 pumping the liquid matrix is ​​usually greater than the load of the second pump 152 drawing in air; therefore, the operating frequency or motor speed of the first pump 151 is less than that of the second pump 152. Thus, within a unit time, the volume of air drawn by the second pump 152 from the first liquid storage chamber 213 into the second liquid storage chamber 411 is greater than the volume of liquid matrix pumped by the first pump 151 from the second liquid storage chamber 411 into the first liquid storage chamber 213; or, the flow rate of the air drawn by the second pump 152 is greater than the flow rate of the liquid matrix drawn by the first pump 151. Therefore, when the first pump 151 and the second pump 152 start working approximately simultaneously, the first liquid storage chamber 213 is always under negative pressure. This negative pressure prevents the liquid matrix in the first liquid storage chamber 213 from seeping out through the atomizing component 29. And for the first liquid storage chamber 213 under negative pressure, since it is connected to the airflow channel through the capillary element 27, the air from the outside atmosphere can enter the first liquid storage chamber 213 in reverse through the airflow channel of the atomizer 200 via the capillary element 27 to partially relieve the negative pressure of the first liquid storage chamber 213.

[0272] When the first pump 151 and the second pump 152 start working at approximately the same time during operation, the second liquid storage chamber 411 is in a positive pressure state because the volume of air entering the second liquid storage chamber 411 is greater than the volume of the pumped liquid matrix. Therefore, according to... Figure 21 As indicated by the middle arrow R31, excess air entering the second liquid storage chamber 411 can exit the second liquid storage chamber 411 through the pressure relief channel 545, thereby relieving pressure in the second liquid storage chamber 411. Alternatively, in some other embodiments, the second pump 152 is activated immediately in response to the activation of the first pump 151.

[0273] In some embodiments, the first pump 151 and / or the second pump 152 are electric pumps with motors, such as DC motors. Due to the different loads on the first pump 151 when pumping liquid matrix and air, the different torque and speed of the motor result in different operating currents for the first pump 151. Specifically, the operating current of the first pump 151 when pumping liquid matrix is ​​greater than the operating current when pumping air. Furthermore, when the first pump 151 is blocked or the first reservoir 213 is completely filled with liquid matrix and cannot be replenished, the motor stops rotating, and the first pump 151 functions as a pure conductor with no energy conversion, thus the operating current of the first pump 151 reaches its maximum peak value.

[0274] In some embodiments, the main circuit board 114 can determine whether the liquid matrix in the second reservoir 411 is depleted by monitoring the operating current of the first pump 151. More specifically, the main circuit board 114 can determine whether the fluid pumped by the first pump 151 is air by monitoring whether the operating current of the first pump 151 is less than a first predetermined threshold, thereby determining whether the liquid matrix in the second reservoir 411 is depleted. The first predetermined threshold can be set based on the current difference when the first pump 151 pumps liquid matrix and air.

[0275] In some embodiments, the main circuit board 114 can determine adverse conditions of the first pump 151 by monitoring its operating current; for example, the first pump 151 may be blocked or the first reservoir 213 may be completely filled with liquid matrix, preventing further replenishment. More specifically, the main circuit board 114 can determine adverse conditions of the first pump 151 by monitoring whether its operating current exceeds a second predetermined threshold. The second predetermined threshold can be set based on the difference in current between when the first pump 151 is pumping liquid matrix and when it is blocked.

[0276] Correspondingly, the main circuit board 114 can also monitor the operating current of the second pump 152 to determine whether the first liquid storage chamber 213 is completely filled with liquid matrix. When the first liquid storage chamber 213 is not filled with liquid matrix, the fluid pumped by the second pump 152 is air, and the operating current of the second pump 152 is relatively small. When the first liquid storage chamber 213 is filled with liquid matrix, the fluid pumped by the second pump 152 is mixed with or contains liquid matrix, and the operating current of the second pump 152 is relatively large. Thus, the main circuit board 114 can determine whether the second free end of the second pipe 233 in the first liquid storage chamber 213 is submerged in liquid matrix or whether the first liquid storage chamber 213 is basically filled with liquid matrix by monitoring that the operating current of the second pump 152 is greater than a predetermined threshold.

[0277] In some embodiments, the main circuit board 114 can control the first pump 151 and the second pump 152 to start working based on the input signal generated by the user through the operation input element 143.

[0278] Alternatively, in some embodiments, the main circuit board 114 may automatically control the first pump 151 and the second pump 152 to start operating according to a predetermined time or frequency, or when the remaining amount of liquid matrix in the first reservoir 213 is lower than a predetermined threshold. For example, in some embodiments, the main circuit board 114 analyzes the user's aerosol inhalation volume or inhalation habits by collecting data such as the number of user inhalations or inhalation duration per day, and then automatically controls the first pump 151 and the second pump 152 to start operating, so that the amount of liquid matrix in the first reservoir 213 is maintained within a predetermined range, such as 2 to 4 mL. For example, in a more specific embodiment, the main circuit board 114 controls the first pump 151 and the second pump 152 to start operating when the remaining amount of liquid matrix in the first reservoir 213 is lower than 2 mL; for example, in a more specific embodiment, the main circuit board 114 controls the first pump 151 and the second pump 152 to start operating to replenish the liquid matrix in the first reservoir 213 during the early morning or morning hours or between 0:00 and 6:00 every day.
