Description

[Technical Field]

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

[0002] Electronic atomizing devices typically include an atomizer and a power supply unit. The atomizer is used to atomize the liquid matrix stored inside to produce an aerosol, while the power supply unit is used to provide the atomizer with the electrical energy required for atomization. Electronic atomizing devices also need to be equipped with an air inlet for external air to enter, so that air can enter the electronic atomizing device during inhalation and carry the aerosol produced after atomization out for the user to inhale.

[0003] Existing air intakes are usually located on the side or bottom of the power supply assembly, and then flow into the atomizer through the internal airflow channel. This method has two drawbacks: firstly, the airflow channel is too long, making it difficult to control the draw resistance; secondly, because the airflow needs to pass through the power supply assembly, there is a risk of failure of the internal electronic components of the power supply assembly. [Utility Model Content]

[0004] This application provides an electronic atomizing device to solve the technical problem in the prior art where air intake from the power supply component leads to poor control of suction resistance or causes the internal electronic components of the power supply component to fail.

The atomizer is provided with a liquid reservoir for storing a liquid matrix and an atomizing assembly for atomizing the liquid matrix to generate an aerosol. The power supply assembly comprises:

[0007] The housing has a first end and a second end disposed opposite to each other along its length, and a first sidewall and a second sidewall extending between the first end and the second end and disposed opposite to each other.

[0008] A nozzle is disposed at the first end, and the nozzle defines a first air outlet for the aerosol to escape from the electronic atomizing device;

[0015] In one embodiment, the containment chamber includes a first opening on the first sidewall and a second opening on the second sidewall, the atomizer being contained in the containment chamber through the first opening or the second opening.

[0016] In one embodiment, the width of the first opening is greater than or equal to the width of the atomizer, thereby allowing the atomizer to be received in the receiving chamber through the first opening, and the width of the second opening is less than the width of the atomizer.

[0017] In one embodiment, the cross-sectional shape of the receiving chamber is non-circular.

[0018] In one embodiment, one of the atomizer and the receiving chamber is provided with guide ribs, and the other is provided with guide grooves that match the guide ribs.

[0019] In one embodiment, the receiving chamber includes a bottom wall, and the power assembly includes an electrical connection terminal that protrudes at least partially from the bottom wall for electrical connection with the atomizer.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0041] One embodiment of this application provides an electronic atomizing device 100, such as... Figure 1 and Figure 2 As shown, the electronic atomizing device includes an atomizer 10 and a power supply component 20. The atomizer 10 is used to store an atomizable liquid matrix and atomize the liquid matrix to generate an aerosol that can be inhaled by the user. The power supply component 20 is used to provide the atomizer 10 with the electrical energy required for atomization.

[0042] The power supply assembly 20 includes a housing 21 having a first end 211 and a second end 212 disposed opposite to each other along its length, and a first sidewall 213 and a second sidewall 214 extending between the first end 211 and the second end 212 and disposed opposite to each other. The housing 21 also includes a receiving chamber 215 extending through the first sidewall 213 and the second sidewall 214, the receiving chamber 215 for removably receiving and holding the atomizer 10. The first end 211 is provided with a mouthpiece 22, which defines a first air outlet 221 for aerosol to escape from the electronic atomization 100. The user can inhale the aerosol by inhaling through the first air outlet 221.

[0043] Please continue reading. Figure 2 The atomizer 10 includes a housing 11, which has a third end 111 and a fourth end 112 disposed opposite to each other along the length of the power supply assembly 20. When the atomizer 10 is housed in the housing chamber 215, the third end 111 faces the mouthpiece 22 and the fourth end 112 is away from the mouthpiece 22. When the atomizer 10 is housed in the housing chamber 215, the second air outlet 1111 and the first air outlet 211 are connected so that the aerosol generated after atomization can enter the first air outlet 211 through the second air outlet 1111. By setting the second air outlet 1111 at the third end 111, the flow path of the aerosol can be shortened, so that the aerosol formed after atomization by the atomizer 10 can quickly reach the first air outlet 211 for the user to inhale.

[0044] like Figure 3 As shown, a liquid storage chamber 13 is provided in the outer shell 11, and a liquid storage component 14 is provided in the liquid storage chamber 13. The liquid storage component 14 is used to absorb and maintain the atomizable liquid matrix in the liquid storage chamber 13. The liquid storage component 14 has a through hole (not shown) that runs longitudinally through the liquid guide component 14. The atomizer 10 also includes an air guide tube 110. One end of the air guide tube 110 is connected to the second air outlet 1111, and the other end extends into the through hole. An atomizing component is provided inside the air guide tube 110. The atomizing component includes a liquid guide component 15 and a heating element 16 attached to the liquid guide component 15. The tube wall of the air guide tube 110 has a notch (not shown). A part of the liquid guide component 15 passes through the notch and contacts the liquid storage component 14. The liquid storage component 14 can then transfer the liquid matrix it stores to the liquid guide component 15, and the liquid guide component 15 can further transfer it to the heating element 16. The heating element 16 can heat and atomize the liquid matrix to generate an aerosol, and release the generated aerosol into the air guide tube 110, and then the air guide tube 110 transmits it to the second air outlet 1111.

[0045] The liquid guiding element 15 and the liquid storage element 14 are made of porous materials, such as cotton fibers, non-woven fabrics, fiberglass ropes, porous glass, or porous ceramics. This allows the liquid storage element 14 and the liquid guiding element 15 to absorb or conduct the liquid matrix through their internal microporous structure or pores. Correspondingly, the heating element 16 can be attached to the liquid guiding element 15 or wound around it by means of printing, deposition, sintering, or physical assembly.

[0046] like Figure 4 As shown, the power supply assembly 20 also includes a battery cell 22 and a main board 23. The main board 23 is equipped with a controller for the electronic atomizing device 100. The power supply assembly 20 also includes an electrical connection terminal 24 that is at least partially exposed in the receiving chamber 215. Meanwhile, the atomizer 10 also includes a conductive electrode 17 that is partially exposed on the end face of the fourth end 112. The conductive electrode 17 is electrically connected to the heating element 16. When the atomizer 10 is received in the receiving chamber 215, the conductive electrode 17 of the atomizer 10 is electrically connected to the electrical connection terminal 24 of the power supply assembly 20, so that the controller can control the battery cell 22 to provide the electrical energy required for atomization to the atomizer 10.

[0047] Please continue reading. Figure 2 and Figure 3 The atomizer 10 has a first surface 113. When the atomizer 10 is housed in the housing chamber 215, at least a portion of the first surface 113 avoids the mating surface of the housing chamber 215 and is exposed to the outside of the housing 21. An air inlet 1131 is provided in the exposed area. The air inlet 1131 is used to provide external air to enter the air inlet of the electronic atomizing device 100. When the user inhales through the first air outlet 221, external air enters the electronic atomizing device 100 through the air inlet 1131, and then flows further into the air guide tube 110, thereby carrying the aerosol released in the air guide tube 110 and flowing into the first air outlet 211 through the second air outlet 1111, thus forming an airflow channel for the atomizer 10. The airflow channel is used to provide an airflow path for the airflow in the atomizer 10. The airflow channel is described in detail below. Figure 3 As shown by arrow R in the diagram. In this embodiment, by providing an air inlet 1131 in the exposed area of ​​the first surface 113, external air can directly enter the atomizer 10 through the air inlet 1131. The airflow does not need to flow through the power supply component 20, thereby avoiding the risk of electronic components in the power supply component 20 failing due to airflow. In addition, allowing external air to enter the atomizer 10 directly through the air inlet 1131 also shortens the airflow path, thus controlling the draw resistance.

[0048] In some embodiments, such as Figure 2As shown, the receiving chamber 215 is located adjacent to the first end 211, so that when the atomizer 10 is received in the receiving chamber 215, it is closer to the mouthpiece 22, and the aerosol generated after atomization can be quickly inhaled by the user.

[0049] In some embodiments, such as Figure 3 As shown, the airflow channel R includes a first part R1 extending from the third end 111 towards the fourth end 112 and a second part R2 substantially perpendicular to the first part R1. The first part R1 connects to the second air outlet 1111, and the second part R2 connects to the outside through the air inlet 1131. This allows the air inlet 1131 to be located below the atomizing component, meaning the distance between the air inlet 1131 and the fourth end 112 is less than the distance between the atomizing component and the fourth end 112. External air entering through the air inlet 1131 can then flow quickly through the atomizing component. This arrangement simplifies the airflow path design between the air inlet 1131 and the atomizing component. If the air inlet 1131 is positioned too high, above the atomizing component, a more complex airflow path needs to be designed to guide the air entering through the air inlet 1131 to the area below the atomizing component. On the other hand, the airflow channel R can shorten its extension length by passing through the first part R1 and the second part R2, which are perpendicular to each other, so that the user can draw in the aerosol generated after atomization in a timely manner.

[0050] And, in some embodiments, such as Figure 3 As shown, the atomizer 10 also includes a seal 18 for sealing the liquid storage chamber 13, and a base 19 installed on the fourth end 112. The seal 18 is supported on the base 19, and a chamber 181 for airflow is defined between the seal 18 and the base 19. The chamber 181 connects the air inlet 1131 and the atomizing assembly, so that after the external air enters from the air inlet 1131, it can flow smoothly to the atomizing assembly through the chamber 181.

[0051] In some embodiments, to facilitate the user inserting or removing the atomizer 10 from the receiving chamber 215, the receiving chamber 215 is configured to receive the atomizer 10 along the thickness direction of the housing 21. That is, the user only needs to move along... Figure 2 The atomizer 10 can be inserted into or removed from the receiving chamber 215 from the X-direction.

[0052] Alternatively, in some embodiments, the atomizer 10 may also be housed in the receiving chamber 215 along the width direction of the housing 21, or removed from the receiving chamber 215, such as... Figure 2 Y direction shown.

[0053] Furthermore, in some embodiments, such as Figure 5As shown, the receiving chamber 215 includes a first opening 2131 on the first sidewall 213 and a second opening 2141 on the second sidewall 214. The atomizer 10 also includes a second surface 114 disposed opposite to the first surface 113. When the atomizer 10 is received in the receiving chamber 215, the first surface 113 is at least partially exposed through the first opening 2131, and the second surface 114 is at least partially exposed through the second opening 2141. The atomizer 10 can be inserted into the receiving chamber 215 through either the first opening 2131 or the second opening 2141, thereby facilitating the user to remove the atomizer 10 from the receiving chamber 215.

[0054] For example, a user inserts the atomizer 10 into the receiving chamber 215 through the first notch 2131. After use, the user applies a pushing force to the atomizer 10 through the first notch 2131, causing the atomizer 10 to detach from the receiving chamber 215 through the second notch 2141. Alternatively, the user applies a pushing force to the atomizer 10 through the second notch 2141, causing the atomizer 10 to detach from the receiving chamber 215 through the first notch 2131.

[0055] And, in some embodiments, such as Figure 6 As shown, the width d1 of the first notch 2131 is greater than or equal to the width of the atomizer 10, while the width d2 of the second notch 2141 is less than the width of the atomizer 10. That is to say, the width d1 of the first notch 2131 is greater than the width of the second notch 2141. Therefore, the atomizer 10 can only be inserted into the receiving chamber 215 through the first notch 2131. During the process of inserting the atomizer 10 into the receiving chamber 215, since the width of the second notch 2141 is less than the width of the atomizer 10, when the atomizer 10 is completely contained in the receiving chamber 215, the edge of the second notch 2141 will abut against the atomizer 10, thereby limiting the atomizer 10 and preventing the atomizer 10 from continuing to move in the receiving chamber 215. This allows the second air outlet 1111 and the first air outlet 211 to be aligned and connected after the atomizer 10 is contained in the receiving chamber 215, and the conductive electrode 17 to be aligned and electrically connected with the heating element 17.

[0056] And, in some embodiments, such as Figure 2 As shown, the cross-sectional shape of the receiving chamber 215 is elliptical. Therefore, when the user inserts the atomizer 10 into the receiving chamber 215, the user needs to adjust the posture of the atomizer 10 to fit the shape of the receiving chamber 215 before the atomizer 10 can be inserted into the receiving chamber 215. The user cannot insert the atomizer 10 into the receiving chamber 215 in any posture. This method can further ensure that after the atomizer 10 is received in the receiving chamber 215, the second air outlet 1111 and the first air outlet 211 are aligned and connected, and the conductive electrode 17 and the heating element 17 are aligned to achieve electrical connection.

[0057] It is easy to understand that the cross-sectional shape of the containment chamber 215 can also be other shapes, such as rectangle, square, cylinder, etc., as long as the cross-sectional shape of the containment chamber 215 is not circular.

[0058] In some embodiments, the inner wall of the receiving chamber 215 is provided with guide ribs, and the atomizer 10 is provided with guide grooves adapted to the guide ribs. The guide ribs and guide grooves cooperate to provide guidance for the atomizer 10 during the process of being installed in the receiving chamber 215. By providing guidance, after the atomizer 10 is received in the receiving chamber 215, the second air outlet 1111 and the first air outlet 211 are aligned and connected, and the conductive electrode 17 and the heating element 17 are aligned to achieve electrical connection.

[0059] In some embodiments, guide ribs may be provided on the atomizer 10, and guide grooves may be provided on the inner wall of the receiving chamber 215.

[0060] Specifically in one embodiment, such as Figure 5 and Figure 6 As shown, the receiving chamber 215 includes a bottom wall 2151, and an electrical connection terminal 24 protrudes at least partially from the bottom wall 2151, thereby exposing at least part of the electrical connection terminal 24 in the receiving chamber 215 so that when the atomizer 10 is received in the receiving chamber 215, the electrical connection terminal 24 and the conductive electrode 17 of the atomizer 10 are electrically connected. A first guide rib 2151a and a second guide rib 2151b are provided on the bottom wall 2151, and the first guide rib 2151a and the second guide rib 2151b are distributed on both sides of the electrical connection terminal 24. On the end face of the fourth end 112 of the atomizer 10, guide grooves 115 are provided, which are adapted to the first guide rib 2151a and the second guide rib 2151b respectively.

[0061] In some embodiments, at least one of the atomizer 10 and the power supply assembly 20 is provided with a soft rubber component, which can be any of silicone, rubber or latex. When the atomizer 10 is housed in the housing chamber 215, the atomizer 10 and the housing chamber 215 can be press-fitted by the soft rubber component, thereby keeping the atomizer 10 in the housing chamber 215.

[0062] For example, in a specific embodiment, such as Figure 2As shown, the soft rubber part 1112 is disposed at the third end 111 of the atomizer 10 and surrounds the second air outlet 1111. The soft rubber part 1112 protrudes at least partially from the end face of the third end 111. When the atomizer 10 is installed into the receiving chamber 215, the inner wall of the receiving chamber 215 squeezes the protruding soft rubber part 1112, thereby causing the atomizer 10 and the receiving chamber 215 to have an interference fit. The interference fit also allows the soft rubber part 1112 to play a sealing role in sealing the second air outlet 1111 and preventing aerosol from leaking from the assembly gap between the atomizer 10 and the inner wall of the receiving chamber 215.

[0063] And, in a specific embodiment, such as Figure 3 , Figure 4 and Figure 5 As shown, the air duct 110 serves as the atomization chamber of the electronic atomizing device 100, providing a space for aerosol release. The atomizer 10 also includes a first air duct 191 disposed on the base 19, which communicates with the atomization chamber. The power supply assembly 20 also includes an airflow sensor (not shown) for sensing negative pressure generated in the atomization chamber, and a second air duct 27 communicating with one side of the airflow sensor. When the atomizer 10 is housed in the housing chamber 215, the first air duct 191 and the second air duct 27 are aligned to form a trigger airflow channel for the airflow sensor. When the user inhales through the first air outlet 221, negative pressure is generated in the atomization chamber, which triggers the airflow sensor to generate an electrical signal. This electrical signal is sent to the controller, which then controls the battery 22 to supply power to the heating element 16 based on the electrical signal.

[0064] like Figure 4 As shown, the power supply assembly 20 is also provided with a soft rubber part 28, which is at least partially exposed in the receiving chamber 215. When the atomizer 10 is received in the receiving chamber 215, the atomizer 10 squeezes the soft rubber part 28 to make the atomizer 10 and the receiving chamber 215 interference fit. In the process of interference fit, the soft rubber part 28 also provides a seal between the atomizer 10 and the power supply assembly 20 to seal the assembly gap between the atomizer 10 and the power supply assembly 20, thereby preventing external air from entering the trigger air passage through the assembly gap, so as to improve the trigger sensitivity of the airflow sensor 26.

[0065] Furthermore, in some embodiments, such as Figure 4 , Figure 5 and Figure 8As shown, the soft rubber part 28 includes an end face 281 and an annular protrusion 282 protruding from the end face 281. The annular protrusion 282 is at least partially exposed in the receiving chamber 215. The annular protrusion 282 surrounds the first air guide hole 191 and the second air guide hole 27. When the atomizer 10 is installed in the receiving chamber 215, the atomizer 10 squeezes the annular protrusion 282 to make the atomizer 10 and the receiving chamber 215 interference fit. During the interference fit, the first air guide hole 191 and the second air guide hole 27 are sealed to prevent external air from entering the first air guide hole 191 and / or the second air guide hole 27 through the assembly gap between the atomizer 10 and the power assembly 20.

[0066] And, in some embodiments, such as Figure 4 and Figure 9 As shown, the soft rubber component 28 also includes a first tubular body 283 extending from the end face 281 away from the receiving chamber 215. The first tubular body 283 extends into the second air guide hole 27 and is hollow to allow airflow. When the atomizer 10 is installed in the receiving chamber 215, the first air guide hole 191 and the first tubular body 283 are aligned to form the trigger air passage of the airflow sensor 26. Since the first tubular body 283 is located in the second air guide hole 27, the diameter of the first tubular body 283 is relatively small. During the heating process, the high-temperature aerosol in the atomizing chamber mixes with the external cold air to form condensate. This condensate drips along the trigger air passage into the power supply assembly 20. By setting the first tubular body 283 with a small diameter, the backflowing condensate can be effectively locked, preventing the condensate from further flowing into the power supply assembly 20.

[0067] And, in some embodiments, such as Figure 4 , Figure 8 and Figure 9 As shown, the power supply assembly 20 also includes a bracket 29 for holding the airflow sensor.
