[0031] As used herein, the terms 'upstream' and 'downstream' are used to describe the relative positions of components, or parts of components, in an electronic atomization device, in the direction of flow of the suction air flow.

[0032] As Figures 1-4 As shown in the drawings, an embodiment of the present application provides an electronic atomization device 10 comprising an atomization assembly 100 and a power supply assembly 200. The electronic atomization device 10 is generally cuboid-shaped, and the X direction in the drawing represents the thickness direction of the electronic atomization device 10, the Y direction represents the width direction of the electronic atomization device 10, and the Z direction represents the length direction of the electronic atomization device 10. The length direction has a size greater than the width direction, and the width direction has a size greater than the thickness direction.

[0033] The atomization assembly 100 and the power supply assembly 200 are detachably connected, for example, the atomization assembly 100 and the power supply assembly 200 are magnetically connected by a magnetic mechanism, the magnetic mechanism comprises a first magnetic element arranged on the atomization assembly 100 and a second magnetic element arranged on the power supply assembly 200, the first magnetic element and the second magnetic element are magnetically attracted to each other. After the atomization assembly 100 and the power supply assembly 200 are connected, they together define the outer shell of the electronic atomization device 10.

[0034] AsFigures 5-7 As shown, the atomization assembly 100 includes a mouthpiece 101, a main shell 102, a bottom cover 103, a sealing member 104, and an atomization core 105.

[0035] The main shell 102 and the bottom cover 103 can be detachably connected by a connecting mechanism, for example, the connecting mechanism includes a clamping hole (not shown) provided on the main shell 102 and a clamping buckle (not shown) provided on the bottom cover 103, and the clamping hole and the clamping buckle can be matched to achieve the clamping connection of the main shell 102 and the bottom cover 103. The main shell 102 and the bottom cover 103 together define an outer shell of the atomization assembly 100.

[0036] The main shell 102 is substantially cuboid-shaped, and the bottom wall and the right side wall of the main shell 102 are both open. The main shell 102 is provided with a partition plate 102a, one end of the partition plate 102a is arranged on the inner side surface of the top wall of the outer shell or the main shell 102, and the other end of the partition plate 102a extends towards the bottom wall of the outer shell or the main shell 102. The hollow part in the outer shell or the main shell 102 can be divided into a first chamber 102b and a second chamber 102c by the partition plate 102a. The top wall of the outer shell or the main shell 102 is provided with a plug-in port 102d, and the plug-in port 102d is in communication with the first chamber 102b. One end of the mouthpiece 101 is removably plugged into the plug-in port 102d, and the other end of the mouthpiece 101 can be held in the mouth of a user for inhaling the aerosol generated by the atomization assembly 100. In further embodiments, a sealing ring (not shown) can be provided on the outer wall of the mouthpiece 101, and the sealing ring can seal the gap between the outer wall of the mouthpiece 101 and the inner wall of the plug-in port 102d.

[0037] The bottom cover 103 is configured in an L shape. The bottom cover 103 includes a first part 103a extending along the width direction and the thickness direction of the electronic atomization device 10, and a second part 103b extending along the length direction of the electronic atomization device 10. The first part 103a covers the opening of the bottom wall of the main shell 102, and the second part 103b covers the opening of the right side wall of the main shell 102.

[0038] The first chamber 102b is formed with a liquid storage cavity 102b1 for storing a liquid substrate. The liquid substrate can be a liquid including a tobacco-containing substance containing volatile tobacco flavoring components, or a liquid including a non-tobacco substance. For example, the liquid substrate can include water, a solvent, ethanol, a plant extract, a flavoring, a flavoring agent, or a vitamin mixture. The flavoring can include menthol, peppermint, spearmint oil, various fruit flavoring components, etc., but is not limited thereto. The flavoring agent can include components capable of providing a user with a variety of flavors or flavors. The vitamin mixture can be a substance mixed with at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but is not limited thereto. In addition, the liquid substrate can include an aerosol forming agent such as glycerol and propylene glycol.

[0039] It should be understood that Figure 8 In an example, the top wall of the outer shell or main shell 102 is further provided with a liquid injection opening 102b2 in fluid communication with the liquid storage cavity 102b1 and a movable plate 102e movable relative to the main shell 102. The liquid injection opening 102b2 can be opened when the movable plate 102e is moved to a first position relative to the main shell 102, so that the user can supplement the liquid matrix in the liquid storage cavity 102b1; the liquid injection opening 102b2 can be closed when the movable plate 102e is moved to a second position relative to the main shell 102.

[0040] In further implementations, a sealing member 106 can be further provided between the movable plate 102e and the top wall of the main shell 102. The sealing member 106 can seal the liquid injection opening 102b2 when the movable plate 102e is moved to the second position relative to the main shell 102, so as to prevent leakage of the liquid matrix. Part of the sealing member 106a can extend into the liquid injection opening 102b2 and form a structure similar to a one-way valve, i.e., the liquid injection component can pass through the part of the sealing member 106a and inject the liquid matrix into the liquid storage cavity 102b1, and when the liquid injection component is removed, the part of the sealing member 106a can prevent the liquid matrix from flowing out of the liquid storage cavity 102b1, thereby preventing leakage of the liquid matrix.

[0041] The sealing member 104 can be made of silica gel material or other flexible material. Similar to the bottom cover 103, the sealing member 104 is configured in an L shape. The sealing member 104 includes a first part of the sealing member 104a extending in the width direction and the thickness direction of the electronic atomization device 10, and a second part of the sealing member 104b extending in the length direction of the electronic atomization device 10. After assembly, the other end of the partition plate 102a is clamped between the first part of the sealing member 104a and the second part of the sealing member 104b; the first part of the sealing member 104a is located in the first chamber 102b, thereby sealing the liquid storage cavity 102b1; and the second part of the sealing member 104b is located in the second chamber 102c, i.e., clamped between the partition plate 102a and the second part of the bottom cover 103b.

[0042] The first part of the sealing member 104a is provided with a first through hole 104a1. The first through hole 104a1 and the plug-in port 102d can be coaxially arranged.

[0043] It should be understood that Figure 9 It should be understood that the atomization core 105 includes a connecting tube 1051, a liquid guide element 1052, and a heating element 1053.

[0044] The upper end of the connecting tube 1051 is inserted into the insertion port 102d after passing through the liquid storage cavity 102b1. A sealing ring (not shown) can be sleeved on the outer wall of the connecting tube 1051 near the upper end, so as to seal the gap between the outer wall of the connecting tube 1051 and the inner wall of the insertion port 102d. The lower end of the connecting tube 1051 is retained on the first sealing member 104a, i.e., is inserted into the first through hole 104a1 of the sealing member 104. In this way, the outer wall of the connecting tube 1051, the sealing member 104 and the cavity wall of the first cavity 102b together define the liquid storage cavity 102b1. The connecting tube 1051 is preferably made of a relatively thin rigid material, such as glass fiber material, stainless steel, etc. The side wall of the connecting tube 1051 also has a liquid guide port 1051a.

[0045] The liquid guide element 1052 can absorb the liquid substrate in the liquid storage cavity 102b1 and deliver the liquid substrate to the heating element 1053. The heating element 1053 can be heated by an electric current supply and transfer heat to the liquid substrate in contact with the heating element 1053 to heat the liquid substrate, thereby generating an aerosol.

[0046] The liquid guide element 1052 has a generally tubular structure. It can be understood that in other examples, it can also have a plate-like structure or other regular or irregular shapes. The liquid guide element 1052 can be made of a flexible fiber material, such as cotton fiber, non-woven fabric or sponge, etc. Alternatively, in other examples, the liquid guide element 1052 can also be a rigid porous body, such as porous ceramic, porous glass, etc. The outer surface of the liquid guide element 1052 has a radially outward protruding portion.

[0047] The heating element 1053 is arranged near the inner surface of the liquid guide element 1052 and can abut against the inner surface of the liquid guide element 1052 or partially or completely embedded in the liquid guide element 1052. The heating element 1053 can be a resistance heating net, a resistance heating coil, etc. The heating element 1053 can be made of a material having a suitable resistance temperature coefficient characteristic, such as stainless steel 316, titanium, nickel, nickel-chromium alloy, etc. In an example, the heating element 1053 can be wound from a sheet-like or net-like base material, and the wound heating element 1053 has a non-closed tubular structure in the circumferential direction, i.e., has a tubular structure with a side opening extending in the length direction of the atomization core 105. The two ends of the heating element 1053 are welded or arranged with leads 1054, which can pass through the sealing member 104 and be arranged outside the sealing member 104, such as passing through the first sealing member 104a of the sealing member 104 and being arranged on the surface of the first sealing member 104a facing the bottom cover 103.

[0048] The liquid guiding element 1052 and the heating element 1053 are disposed within the connecting pipe 1051. Preferably, the tubular liquid guiding element 1052 is coaxially arranged with the connecting pipe 1051. Part of the liquid guiding element 1052 is exposed in the liquid storage chamber 102b1 through the liquid guiding port 1051a of the connecting pipe 1051, thereby allowing the liquid matrix in the liquid storage chamber 102b1 to flow into the atomizing core 105 through the liquid guiding port 1051a, that is, to be absorbed by the liquid guiding element 1052 and atomized by the heating element 1053 to generate an inhalable aerosol.

[0049] Please refer to Figures 5-7 To understand this, in one example, an air inlet 103b1 is provided on the second part of the bottom cover 103, the bottom cover 103b, or the right side wall of the outer casing. The air inlet 103b1 communicates with the second chamber 102c. The atomizing assembly 100 has an airflow channel extending from the air inlet 103b1 to the mouthpiece opening at the other end of the mouthpiece 101. Specifically, as... Figure 7 As shown in S1, air can flow into the atomizing assembly 100 through the air inlet 103b1, that is, into the second chamber 102c. Then, it flows in a different direction along the gap between the inner surface of the second part of the sealing member 104b and the inner surface of the second part of the bottom cover 103b or the inner surface of the right side wall of the outer shell towards the first part of the bottom cover 103a of the bottom cover 103. Then, it flows in a different direction again along the gap between the inner surface of the first part of the sealing member 104a and the inner surface of the first part of the bottom cover 103a or the inner surface of the bottom wall of the outer shell towards the first through hole 104a1, thereby flowing into the first through hole 104a1. After passing through the atomizing core 105, it mixes with the aerosol generated by the heating element 1053 and flows into the mouthpiece 101, and finally flows out from the mouthpiece.

[0050] In one example, a groove 104c is provided on the surface of the seal 104 facing the bottom cover 103 (or the surface facing the right side wall and bottom wall of the housing), extending from the first through hole 104a1 to near the air inlet 103b1. The groove 104c can increase or form the gap between the second part of the seal 104b and the second part of the bottom cover 103b, as well as the gap between the first part of the seal 104a and the first part of the bottom cover 103a, facilitating airflow from the air inlet 103b1 into the first through hole 104a1.

[0051] In one example, an absorbent medium 107, such as fiber cotton, is also provided between the seal 104 and the bottom cover 103. The absorbent medium 107 is sandwiched between the first part of the seal 104a and the first part of the bottom cover 103a. One end of the absorbent medium 107 is located near the first through hole 104a1, and the other end of the absorbent medium 107 is located near the left side wall of the outer shell or the main shell 102, that is, extending in a direction away from the second part of the seal 104b. The absorbent medium 107 can absorb condensate or condensate that falls from the first through hole 104a1.

[0052] In one example, the second part of the bottom cover 103, the bottom cover 103b, is also provided with a third through hole 103b2. The third through hole 103b2 is spaced apart from the air inlet 103b1. The third through hole 103b2 is connected to the second chamber 102c and to the airflow channel in the atomizing assembly 100.

[0053] In one example, the atomizing assembly 100 further includes a first electrode assembly 108, which includes a positive electrode 108a and a negative electrode 108b spaced apart. The first electrode assembly 108 preferably employs a flexible electrode, such as a columnar POGOPIN. One end of the first electrode assembly 108 is exposed on the outer surface of the bottom cover 103 or the bottom wall of the housing, and the other end of the first electrode assembly 108 passes through the bottom cover 103 and can maintain contact with the lead 1054 of the heating element 1053 to form an electrical connection.

[0054] In one example, at least one first magnetic element 109 is also provided on the outer surface of the bottom cover 103, through which the atomizing component 100 and the power supply component 200 can be magnetically connected.

[0055] like Figures 10-12 As shown, the power supply assembly 200 includes:

[0056] The shell 201 is roughly rectangular in shape. The upper end of the shell 201 is open, and the lower end of the shell 201 is closed.

[0057] A support 202 is disposed within the housing 201. Similar to the bottom cover 103, the support 202 is configured in an L-shape. The support 202 includes a first portion 202a extending along the width and thickness directions of the electronic atomizing device 10, and a second portion 202b extending along the length direction of the electronic atomizing device 10. The support 202 divides the cavity within the housing 201 into a first receiving cavity 201a and a second receiving cavity 201b, namely the first receiving cavity 201a. The first receiving cavity 201a communicates with the upper opening of the housing 201, and the first receiving cavity 201a and the second receiving cavity 201b are arranged along the length direction of the electronic atomizing device 10. The second receiving cavity 201b is a substantially sealed chamber.

[0058] When the atomization assembly 100 is connected with the power supply assembly 200, for example, the atomization assembly 100 is assembled into the first accommodating cavity 201a from top to bottom through the upper end opening of the shell 201, the first part of the bracket 202a is close to or next to the first part of the bottom cover 103a, and the second part of the bracket 202b is close to or next to the second part of the bottom cover 103b, that is, the second part of the bracket 202b is located between the right side wall of the second part of the bottom cover 103b or the shell of the atomization assembly 100 and the right side wall of the shell 201. At this time, part of the atomization assembly 100 is accommodated in the first accommodating cavity 201a, and the other end of the suction nozzle piece 101 is exposed outside the shell 201; in addition, the air inlet 103b1 on the bottom cover 103 is also located in the shell 201, that is, in the first accommodating cavity 201a.

[0059] Further in the implementation, in order to facilitate the removal of the atomization assembly 100 from the first accommodating cavity 201a, a notch groove 201c is further provided on the right side wall of the shell 201, through which part of the atomization assembly 100 is exposed outside the shell 201. The user can operate the exposed part of the atomization assembly 100 with one hand to remove the atomization assembly 100 from the first accommodating cavity 201a.

[0060] The battery cell 203 is arranged in the second accommodating cavity 201b. The battery cell 203 is used to provide power. The battery cell 203 can be a primary battery cell or a secondary battery cell.

[0061] The circuit board 204 is arranged in the second accommodating cavity 201b. The circuit board 204 and the battery cell 203 are arranged in sequence along the width direction of the electronic atomization device 10. The circuit board 204 is electrically connected with the battery cell 203, and the circuit board 204 is used to control the overall operation of the electronic atomization device 10.

[0062] In an example, the power supply assembly 200 further comprises a second through hole 205, one end of the second through hole 205 penetrates through the right side wall of the shell 201, and the other end of the second through hole 205 penetrates through the second part of the bracket 202b of the bracket 202.

[0063] When the atomization assembly 100 is connected with the power supply assembly 200, the air inlet 103b1 on the bottom cover 103 is located in the first accommodating cavity 201a and is in alignment and communication with the second through hole 205. In this way, external air can flow into the air inlet 103b1 through the second through hole 205, which can be specifically referred to as S1 shown in Figure 3

[0064] ​In a further embodiment, the power supply assembly 200 further comprises an air regulating member 206. The air regulating member 206 is sandwiched between the housing 201 and the second portion 202b of the bracket 202, and in a preferred embodiment, a portion of the air regulating member 206 is exposed on the right side wall of the housing 201. A user can adjust the size of the second through hole 205, and thus the air flow into the air inlet 103b1, by operating the exposed portion of the air regulating member 206, such as sliding the air regulating member 206 up and down.

[0065] In an example, the power supply assembly 200 further comprises a second electrode assembly 207. One end of the second electrode assembly 207 is exposed in the first accommodating cavity 201a through the first portion 202a of the bracket 202, and the other end of the second electrode assembly 207 is electrically connected to the circuit board 204. The second electrode assembly 207 preferably employs a resilient electrode, such as a POGO PIN in a columnar shape. The second electrode assembly 207 comprises a positive electrode 207a and a negative electrode 207b arranged at intervals.

[0066] When the atomization assembly 100 is connected to the power supply assembly 200, the first electrode assembly 108 and the second electrode assembly 207 are in contact, thereby forming an electrical connection. That is, the positive electrode 108a and the positive electrode 207a are in contact, and the negative electrode 108b and the negative electrode 207b are in contact.

[0067] In an example, the power supply assembly 200 further comprises an air flow sensor 208. The air flow sensor 208 can be a common microphone or a MEMS (Micro Electro Mechanical System) sensor; in a preferred embodiment, the air flow sensor 208 employs a small-volume silicon microphone that can be directly mounted on the circuit board 204 without the need for lead soldering.

[0068] Please understand that Figure 13 The second portion 202b of the bracket 202 is further provided with a fourth through hole 202b1, and a sensing channel is formed between the sensing surface of the air flow sensor 208 and the fourth through hole 202b1, as shown by the S2 dashed arrow in the figure.

[0069] When the atomization assembly 100 is connected to the power supply assembly 200, the third through hole 103b2 on the bottom cover 103 is located in the first accommodating cavity 201a and is in alignment and communication with the fourth through hole 202b1, thereby being in communication with the air flow channel in the atomization assembly 100. In this way, when the electronic atomization device 10 is being smoked, the air flow sensor 208 can sense the change in air flow in the air flow channel through the sensing channel S2, thereby generating a corresponding electrical signal, which facilitates the control of the heating element 1053 by the control unit in the circuit board 204.

[0070] When the aerosol generated by heating the heating element 1053 and atomization flows towards the sensing surface of the airflow sensor 208 through the sensing channel S2, at least one direction change is required to reach the sensing surface of the airflow sensor 208 (three direction changes are required to reach the sensing surface, as shown in the figure, refer to S2). The configuration of the sensing channel S2 can reduce the damage of the aerosol to the airflow sensor 208.

[0071] In an example, the power supply assembly 200 further comprises a second magnetic element 209, and the cooperation of the first magnetic element 109 and the second magnetic element 209 can realize the magnetic attraction connection between the atomization assembly 100 and the power supply assembly 200.

[0072] It should be noted that the preferred embodiments of the present application are given in the specification and drawings of the present application, but the present application can be implemented in many different forms, and is not limited to the embodiments described in the specification. These embodiments are not additional limitations on the content of the present application, and the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive. Furthermore, the above technical features continue to be combined with each other, forming various embodiments not listed above, which are considered to be within the scope of the present application. Furthermore, for those skilled in the art, the above description can be improved or changed, and all these improvements and changes shall fall within the scope of the claims of the present application.
