[0002] An electronic atomization device is an electronic product that generates an aerosol for a user to inhale by atomizing a liquid matrix. It generally has two parts: an atomizer and a power supply component; the atomizer stores a liquid matrix inside and is provided with an atomization component for atomizing the liquid matrix, and the power supply component includes a battery and a circuit board.

[0003] Limited by various factors, such as cost, regulations, etc., the amount of liquid matrix stored inside the atomizer is generally relatively small. When the liquid matrix is consumed, methods such as refilling or replacing the atomizer can be adopted to continue using it, or it can be directly discarded. The above methods bring inconvenience to users on the one hand, reducing the user experience, and on the other hand, increasing the user's usage cost. Utility Model Content

[0004] This application aims to provide a liquid storage component, an atomization component, and an electronic atomization device to avoid the problems of inconvenience to users and increased user usage cost caused by existing electronic atomization devices.

[0021] In the first position, the first through hole is communicated with the other end of the first channel, and the second through hole is communicated with the second liquid storage cavity, so that the second liquid matrix in the second liquid storage cavity sequentially flows through the second through hole, the liquid passing channel and the first through hole and flows into the first channel;

[0022] In the second position, the first through hole is misaligned with the other end of the first channel, so as not to be communicated with the other end of the first channel; the second through hole is hidden in the connecting channel, so as not to be communicated with the second liquid storage cavity.

[0023] In one example, the switch further includes a first seal and a second seal, and the first through hole is disposed between the first seal and the second seal.

[0032] In one example, the switch is disposed on the second housing assembly.

[0033] In one example, the volume of the first liquid storage cavity is smaller than the volume of the second liquid storage cavity.

[0034] In one example, the capacity of the first liquid matrix stored in the first liquid storage cavity is between 0.1 ml and 2 ml, and the capacity of the second liquid matrix stored in the second liquid storage cavity is between 2 ml and 10 ml.

[0056] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used in this specification in the description of the present application are only for the purpose of describing specific embodiments and are not used to limit the present application. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0057] As used herein, terms such as "first", "second", etc. are used to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly indicating the quantity, specific order or primary-secondary relationship of the indicated technical features.

[0058] An embodiment of the present application provides an electronic atomization device, which can be seen Figure 1 as shown, including an atomization assembly 10 that stores a liquid matrix and atomizes it to generate an aerosol, and a power supply assembly 20 that powers the atomization assembly 10. The atomization assembly 10 is detachably connected to the power supply assembly 20.

[0059] In Figure 1In the illustrated example, the power supply assembly 20 includes a receiving cavity 21 provided at one end in the longitudinal direction for receiving and accommodating at least a part of the atomizing assembly 10, and electrical contacts 22 at least partially exposed in the receiving cavity 21 for making electrical connection with the atomizing assembly 10 and thus powering the atomizing assembly 10 when at least a part of the atomizing assembly 10 is received and accommodated in the power supply assembly 20. An electrical contact 11 is provided at the end of the atomizing assembly 10 opposite to the power supply assembly 20 in the longitudinal direction. Thus, when at least a part of the atomizing assembly 10 is received in the receiving cavity 21, the electrical contact 11 forms an electrical connection by contacting and abutting against the electrical contact 22.

[0060] In Figure 1 the illustrated example, a seal 23 is provided in the power supply assembly 20, and at least a part of the internal space of the power supply assembly 20 is separated by the seal 23 to form the above-mentioned receiving cavity 21. The seal 23 is configured to extend in a direction perpendicular to the longitudinal direction of the power supply assembly 20, and is preferably made of a flexible material such as silicone, so as to prevent the liquid matrix seeping from the atomizing assembly 10 into the receiving cavity 21 from flowing to components such as the control unit 24 and the sensor 25 inside the power supply assembly 20.

[0061] In Figure 1 the illustrated example, the power supply assembly 20 further includes a battery cell 26 for power supply at the other end away from the receiving cavity 21 in the longitudinal direction; and a control unit 24 provided between the battery cell 26 and the receiving cavity 21, and the control unit 24 operably guides current between the battery cell 26 and the electrical contacts 22. In use, the power supply assembly 20 includes a sensor 25 for sensing the suction airflow generated when the atomizing assembly 10 is suctioned, and then the control unit 24 controls the battery cell 26 to supply power to the atomizing assembly 10 according to the detection signal of the sensor 25.

[0062] In Figure 1 the illustrated example, a charging interface 27 is provided at the other end of the power supply assembly 20 away from the receiving cavity 21 for charging the battery cell 26.

[0063] It can be understood that in other examples, it is also feasible that the atomizing assembly 10 and the power supply assembly 20 are non-detachably connected, that is, integrally formed.

[0064] As Figures 2 - 7 shown, an atomizing assembly 10 provided in an embodiment of the present application includes an atomizing component 100 and a liquid storage component 200.

[0065] The atomizing component 100 includes a housing assembly 101, and the housing assembly 101 is composed of a main housing 101a and a bottom cover 101b provided at the bottom end of the main housing 101a. In other examples, the housing assembly 101 may also be integrally formed.

[0066] The top of the housing assembly 101 is provided with a mouthpiece 102. In the illustrated example in the figure, the mouthpiece 102 is integrally formed with the housing assembly 101; in other examples, the mouthpiece 102 can also be separately formed from the housing assembly 101. The mouthpiece 102 is used for the user to inhale the aerosol generated by atomization.

[0067] A liquid storage cavity 103 for storing a first liquid matrix is formed inside the housing assembly 101. The first liquid matrix can be a liquid including a tobacco-containing substance containing volatile tobacco flavor components, or can also be a liquid including non-tobacco substances. For example, the liquid matrix can include water, solvents, ethanol, plant extracts, spices, flavoring agents, or vitamin mixtures. The spices can include menthol, peppermint, spearmint oil, various fruit flavor components, etc., but are not limited thereto. The flavoring agents can include components that can provide various scents or flavors to the user. 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. Additionally, the first liquid matrix can include aerosol-forming agents such as glycerol and propylene glycol.

[0068] A liquid storage medium 103a is provided in the liquid storage cavity 103. A seal 103b is provided at the upper end of the liquid storage cavity 103, and a seal 103c is provided at the lower end of the liquid storage cavity 103. The upper and lower ends of the liquid storage cavity 103 are sealed by the seal 103b and the seal 103c.

[0069] The liquid storage medium 103a is made of, for example, a fibrous material or a porous material. The liquid storage medium 103a is generally in a tubular structure. The liquid storage medium 103a can adsorb and hold the first liquid matrix and supply the first liquid matrix to the atomization core 104. When the liquid storage medium 103a reaches a saturated state after liquid injection, the content of the liquid matrix in the liquid storage medium 103a is between 0.1 ml and 2 ml, such as 0.5 ml, 0.8 ml, 1 ml, 1.5 ml, or 2 ml, etc. A partial space between the end face of the liquid storage medium 103a and the seal 103b defines an air part.

[0070] An atomization core 104 is provided inside the housing assembly 101. The atomization core 104 is used for atomizing the liquid matrix to generate an aerosol.

[0071] As Figure 8 shown, the atomization core 104 includes a liquid guiding element 104a and a heating element 104b. The liquid guiding element 104a can suck the liquid matrix in the liquid storage medium 103a and transfer the liquid matrix to the heating element 104b. The heating element 104b can be heated by current supply and transfer heat to the liquid matrix in contact with the heating element 104b to heat the liquid matrix, thereby generating an aerosol.

[0072] The liquid guiding element 104a is configured as a tubular structure. It is understandable that it can also be a plate-like structure or other regular or irregular shapes. The liquid guiding element 104a can be made of a flexible fiber material, such as prepared from cotton fiber, non-woven fabric or sponge body, etc. Or, in other examples, the liquid guiding element 104a can also be a rigid porous body, such as porous ceramics, porous glass, etc. The outer surface of the liquid guiding element 104a has a radially outward protruding portion 104a1.

[0073] The heating element 104b is disposed close to the inner surface of the liquid guiding element 104a. It can be attached to the inner surface of the liquid guiding element 104a, or partially or completely embedded in the liquid guiding element 104a. The heating element 104b can be a resistance heating mesh, a resistance heating coil, etc. The heating element 104b can be made of a material with suitable resistance temperature coefficient characteristics, such as: stainless steel 316, titanium, nickel, nickel-chromium alloy, etc. In one example, the heating element 104b can be formed by winding a sheet-like or net-like base material. The wound heating element 104b is a non-closed tubular structure in the circumferential direction, that is, a tubular structure with a side opening extending along the length direction of the atomizing member 100. Both ends of the heating element 104b are welded or provided with conductive pins 104c and conductive pins 104d. The conductive pins 104c and conductive pins 104d are electrically connected to the two electrical contacts 11 in a one-to-one correspondence for guiding current on the heating element 104b. In other examples, the heating element 104b can be arranged to be wound around the structure of the liquid guiding element 104a.

[0074] An air flow channel 105 is further provided in the housing assembly 101 to transmit the aerosol generated by the atomizing core 104 to the mouthpiece 102 for the user to inhale. The lower end of the air flow channel 105 is communicated with the air inlet 109, and the air inlet 109 is provided on the bottom cover 101b of the housing assembly 101; the upper end of the air flow channel 105 is connected to the mouthpiece 102, that is, communicated with the air outlet Figure 4 (the dotted arrow in is the air flow direction in the air flow channel 105).

[0075] As Figure 9 shown, a connecting pipe 105a is provided in the housing assembly 101. The hollow part inside the connecting pipe 105a defines a part of the air flow channel 105. The connecting pipe 105a extends along the axial direction of the liquid storage cavity 103. In a preferred implementation, the upper end of the connecting pipe 105a is connected to the seal 103b, and the lower end of the connecting pipe 105a is connected to the seal 103c. The connecting pipe 105a is preferably made of a relatively thin rigid material, such as glass fiber material, stainless steel, etc.

[0076] In a preferred implementation, the liquid storage medium 103a is sleeved on the connecting pipe 105a; the inner diameter of the liquid storage medium 103a is slightly smaller than the outer diameter of the connecting pipe 105a, so that the liquid storage medium 103a is tightly sleeved on the connecting pipe 105a. The atomization core 104 is arranged inside the connecting pipe 105a. The atomization core 104 is coaxially arranged with the connecting pipe 105a. A liquid guiding port 105a1 is also provided on the side wall of the connecting pipe 105a near the lower end of the connecting pipe 105a. The liquid storage medium 103a covers the liquid guiding port 105a1, and a part of the liquid guiding element 104a is exposed in the liquid storage cavity 103 through the liquid guiding port 105a1, so that this part of the liquid guiding element 104a is arranged close to the liquid storage medium 103a or remains in contact with the liquid storage medium 103a. Furthermore, the liquid matrix in the liquid storage cavity 103 flows into the atomization core 104 through the liquid guiding port 105a1, that is, it is absorbed by the liquid guiding element 104a and atomized by the heating element 104b to generate an inhalable aerosol.

[0077] A notch groove 105a2 is also provided on the side wall of the connecting pipe 105a. The notch groove 105a2 extends from the lower end of the connecting pipe 105a towards the upper end of the connecting pipe 105a. The protruding part 104a1 of the liquid guiding element 104a extends into the notch groove 105a2, so as to be exposed in the liquid storage cavity 103. After assembly, a part of the liquid storage medium 103a remains in contact with the protruding part 104a1, which is beneficial for the liquid guiding element 104a to absorb the liquid matrix.

[0078] Please refer to Figures 10 - 12 for understanding. The liquid storage component 200 includes a housing assembly 201. A bracket 205, a seal 206, a seal 207, a holding member 208 and a switch 209 are arranged inside the housing assembly 201. In Figure 10 the example, the housing assembly 201 is integrally formed; in other examples, the housing assembly 201 can be composed of multiple components.

[0079] A liquid storage cavity 202 for storing the second liquid matrix is formed inside the housing assembly 201. One end of the liquid storage cavity 202 is closed and the other end is open. The bracket 205, the seal 206, the seal 207, the holding member 208 and the switch 209 can be assembled into the liquid storage cavity 202 together from the open end of the liquid storage cavity 202.

[0080] Similar to the first liquid matrix, the second liquid matrix can be a liquid containing a tobacco-containing substance with volatile tobacco flavor components, or can also be a liquid containing non-tobacco substances. For example, the liquid matrix can include water, solvents, ethanol, plant extracts, spices, flavorants, or vitamin mixtures. The spices can include menthol, peppermint, spearmint oil, various fruit flavor components, etc., but are not limited thereto. The flavorants can include components that can provide various scents or flavors to the user. 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. Additionally, the second liquid matrix can include aerosol-forming agents such as glycerin and propylene glycol.

[0081] It should be noted that the components or properties of the second liquid matrix can be different from or the same as those of the first liquid matrix. For example, in some examples, the composition of the second liquid matrix is different from that of the first liquid matrix, or the concentration of the second liquid matrix is different from that of the first liquid matrix. For example, in some other examples, the components of the second liquid matrix are exactly the same as those of the first liquid matrix. The second liquid matrix can be a part of a certain liquid formulation, while the first liquid matrix can be another part of a certain liquid formulation. The second liquid matrix can be introduced into the liquid storage cavity 103 as a supplementary source of the first liquid matrix, thereby increasing the number of puffs of the electronic atomization device.

[0082] The volume of the liquid storage cavity 202 is larger than that of the liquid storage cavity 103. Generally, the capacity of the second liquid matrix stored in the liquid storage cavity 202 ranges from 2 ml to 10 ml, such as 2 ml, 4 ml, 5 ml, 6 ml, 8 ml, 10 ml, etc. It can be understood that the volume of the liquid storage cavity 202 is slightly larger than the capacity of the second liquid matrix stored. In this way, after the second liquid matrix is stored in the liquid storage cavity 202, it can be divided into two parts, one part is the air part, and the other part is the liquid matrix part. Usually, no liquid storage medium is provided in the liquid storage cavity 202.

[0083] The liquid storage component 200 is independent of the atomization component 100. For example, before leaving the factory, the liquid storage component 200 and the atomization component 100 are separated, and the user can assemble the liquid storage component 200 and the atomization component 100 during use. In one example, the liquid storage component 200 and the atomization component 100 are detachably connected, that is, the housing assembly 201 and the housing assembly 101 are detachably connected, such as snap connection, magnetic connection, etc. In one example, the liquid storage component 200 cannot be disassembled again once it is connected to the atomization component 100. It can be understood that it is also feasible if the liquid storage component 200 and the atomization component 100 are assembled before leaving the factory.

[0084] The housing assembly 201 is provided with a receiving cavity 203 for receiving or accommodating at least a part of the housing assembly 101. Specifically, the receiving cavity 203 penetrates through the end faces at the upper and lower ends of the housing assembly 201 and is separated from the liquid storage cavity 202 by a partition wall 204. The housing assembly 101 can be assembled into the receiving cavity 203 from the opening at the lower end face of the housing assembly 201, and the suction nozzle 102 extends out from the opening at the upper end face of the housing assembly 201. In a further implementation, a clamping groove (not shown) may be provided on the inner wall of the receiving cavity 203, and a snap connector 101a1 is provided on the outer wall of the housing assembly 101. Through the cooperation of the clamping groove and the snap connector 101a1, the snap connection between the housing assembly 201 and the housing assembly 101 is achieved. After the housing assembly 201 and the housing assembly 101 are connected, they jointly define the outer shell of the atomization component 100. It can be understood that the connection manner between the housing assembly 201 and the housing assembly 101 is not limited to the above situation.

[0085] When the housing assembly 201 and the housing assembly 101 are connected, the liquid storage cavity 103 and the liquid storage cavity 202 are arranged in sequence substantially along the width direction of the atomization component 100. The liquid storage cavity 103 is arranged near the left end of the atomization component 100, while the liquid storage cavity 202 is arranged near the right end of the atomization component 100. It can be understood that the arrangement of the liquid storage cavity 103 and the liquid storage cavity 202 is not limited to the above situation.

[0086] In one example, the housing assembly 101 further includes through holes 108 and 107 arranged at intervals. One end of the through hole 108 is communicated with the liquid storage cavity 103, and the other end of the through hole 108 protrudes from the right side wall of the housing assembly 101 and is communicated with the outside of the housing assembly 101; one end of the through hole 107 is communicated with the liquid storage cavity 103, and the other end of the through hole 107 protrudes from the right side wall of the housing assembly 101 and is communicated with the outside of the housing assembly 101. Liquid matrix can be replenished to the liquid storage cavity 103 through the through hole 108, and air can be replenished to or discharged from the liquid storage cavity 103 through the through hole 107. The through hole 108 is arranged adjacent to the through hole 107 and is spaced longitudinally along the housing assembly 101. The advantage of arranging the through hole 108 adjacent to the through hole 107 is that the same seal can be used to connect the through holes 108, 107 and the liquid storage component, thereby improving the sealing reliability.

[0087] In a specific implementation, one end of the through hole 107 can be communicated with the air part of the liquid storage cavity 103 through the gap between the liquid storage medium 103a and the wall defining the liquid storage cavity 103. For example, the liquid storage medium 103a has a notch groove, and a gap is formed between the notch groove and the wall defining the liquid storage cavity 103, so as to communicate the through hole 107 with the air part of the liquid storage cavity 103; alternatively, the liquid storage medium 103a has a ventilation hole, and the through hole 107 is communicated with the air part of the liquid storage cavity 103 through the ventilation hole.

[0088] In a specific implementation, the external air can also be partially communicated with the air in the liquid storage cavity 103 through the gap between the connecting pipe 105a and the seal 103c.

[0089] When the housing assembly 201 and the housing assembly 101 are not connected, the through-hole 108 or the through-hole 107 can be blocked by a seal, such as being blocked by a removable silicone plug or a silicone cap, or can also be blocked by a pierceable film member.

[0090] The bracket 205 is provided with a spaced-apart receiving cavity 2051 and a connecting channel 2052. The receiving cavity 2051 extends along the width direction of the atomizing member 100 and communicates with the outside of the bracket 205. When the bracket 205 is assembled to the liquid storage cavity 202, the wall defining the receiving cavity 2051 can be snapped onto the notch groove 204a of the partition wall 204. The connecting channel 2052 extends along the longitudinal direction of the atomizing member 100, and one end communicates with the liquid storage cavity 202 and the other end communicates with the outside of the bracket 205.

[0091] The bracket 205 is further provided with a through-hole 2051a and a through-hole 2051b. The through-hole 2051a communicates the receiving cavity 2051 and the liquid storage cavity 202, and the through-hole 2051b communicates the receiving cavity 2051 and the connecting channel 2052. In the example in the figure, the through-hole 2051a is provided on the wall between the receiving cavity 2051 and the liquid storage cavity 202, the through-hole 2051b is provided on the wall between the receiving cavity 2051 and the connecting channel 2052, and one end of the through-hole 2051b protrudes from the wall between the receiving cavity 2051 and the connecting channel 2052 and extends into the receiving cavity 2051.

[0092] The seal 206 is provided on the bracket 205. Part of the seal 206 is located between the outer surface of the bracket 205 and the inner surface of the wall defining the liquid storage cavity 202, so as to seal the gap between the outer surface of the bracket 205 and the inner surface of the wall defining the liquid storage cavity 202. The seal 206 covers the through-hole 2051a and the connecting channel 2052, and has through-holes corresponding to the through-hole 2051a and the connecting channel 2052 one by one. For example, the through-hole 2061 in the figure communicates with the connecting channel 2052, and the through-hole 2062 communicates with the through-hole 2051a.

[0093] The seal 207 is received in the receiving cavity 2051. The seal 207 has a through hole 2071 and a through hole 2072. The through hole 2071 and the through hole 2072 are adjacent to each other and are arranged at intervals along the longitudinal direction of the housing assembly 201. When the seal 207 is assembled into the receiving cavity 2051, the through hole 2071 is aligned and communicated with the through hole 2051a (the through hole 2071, the through hole 2051a, and the through hole 2062 form a fourth channel), and one end of the through hole 2051b extends into the through hole 2072, so that the through hole 2072 is communicated with the through hole 2051b (the through hole 2072 and the through hole 2051b form a third channel). The outer surface of the seal 207 also has a plurality of convex rings (not shown), and the convex rings abut against the inner surface of the wall that defines the receiving cavity 2051, so as to form a good sealing effect.

[0094] Both the above-mentioned seal 206 and the seal 207 are made of a flexible material, such as silica gel.

[0095] The retaining member 208 is sleeved on the wall that defines the receiving cavity 2051. The retaining member 208 is used to hold the seal 207 in the receiving cavity 2051 to prevent the seal 207 from moving out of the receiving cavity 2051.

[0096] Similar to the foregoing, when the housing assembly 201 and the housing assembly 101 are not connected, the through hole 2071 or the through hole 2072 can be blocked by a seal, such as being blocked by a removable silica gel plug or a silica gel cap, or can also be blocked by a pierceable film member.

[0097] When the housing assembly 201 and the housing assembly 101 are connected, at least a part of the wall that defines the through hole 108 and the through hole 107 extends into or is received in the seal 207, so that the through hole 107 is communicated with the through hole 2071, and the through hole 108 is communicated with the through hole 2072. In this way, the air part of the liquid storage cavity 103 can be communicated with the air part of the liquid storage cavity 202, and the liquid matrix in the liquid storage cavity 202 can be timely replenished into the liquid storage cavity 103.

[0098] In this case, the through-hole 108, the through-hole 2072, and the through-hole 2051b together define a liquid channel (the first channel) for providing a fluid path that enables the flow of the first liquid matrix and / or the second liquid matrix between the liquid storage chamber 103 and the liquid storage chamber 202; one end of the liquid channel (the end of the through-hole 108 close to the liquid storage chamber 103) communicates with the liquid storage chamber 103, and the other end of the liquid channel (the end of the through-hole 2051b close to the connection channel 2052) communicates with the liquid storage chamber 202. The through-hole 107, the through-hole 2071, the through-hole 2051a, and the through-hole 2062 together define an air channel (the second channel) for providing an air exchange path that enables air to communicate between the liquid storage chamber 103 and the liquid storage chamber 202; one end of the air channel (the end of the through-hole 107 close to the liquid storage chamber 103) communicates with the air part of the liquid storage chamber 103, and the other end of the air channel (the end of the through-hole 2062 close to the liquid storage chamber 202) communicates with the air part of the liquid storage chamber 202. At least part of the air channel and at least part of the liquid channel are adjacent to each other and are arranged at intervals along the longitudinal direction of the housing assembly 101 or the housing assembly 201.

[0099] The air pressure difference between the liquid storage chamber 103 and the liquid storage chamber 202 can be balanced through the air channel, so that the second liquid matrix stored in the liquid storage chamber 202 can smoothly flow through the liquid channel to the liquid storage chamber 103, timely replenish the consumed liquid matrix in the liquid storage chamber 103, and avoid the negative pressure generated as the liquid matrix in the liquid storage chamber 103 decreases from preventing the remaining liquid matrix from further flowing into the liquid storage chamber 202. As can be seen from the foregoing, external air can also communicate with the air part of the liquid storage chamber 103 through the gap between the connecting pipe 105a and the seal 103c. Therefore, external air can also achieve air exchange with the air part of the liquid storage chamber 103 and / or the liquid storage chamber 202.

[0100] As Figure 3 、 4, as shown in FIGS. 7, in a further implementation, a liquid guiding element 106 is further provided in the liquid storage cavity 103. The liquid guiding element 106 is generally in a tubular structure. The liquid guiding element 106 and the liquid storage medium 103a are arranged in sequence along the axial direction of the liquid storage cavity 103. The liquid guiding element 106 is disposed close to the through hole 108, that is, the liquid guiding element 106 is in communication with the liquid channel, and the through hole 108 is covered by the liquid guiding element 106. The upper surface of the liquid guiding element 106 is in contact with the lower surface of the liquid storage medium 103a, the lower surface of the liquid guiding element 106 is in contact with the bottom of the liquid storage cavity 103, and the outer surface of the liquid guiding element 106 is in contact with the wall defining the liquid storage cavity 103. In this way, when the second liquid matrix in the liquid storage cavity 202 flows through the liquid channel to the liquid storage cavity 103, it can be sucked by the liquid guiding element 106 and transferred to the liquid storage medium 103a, and then indirectly transferred to the liquid guiding element 104a in the atomization core 104, that is, sucked by the liquid guiding element 104a in the atomization core 104. With such a setting, the second liquid matrix stored in the liquid storage cavity 202 can flow more smoothly to the atomization core 104, avoiding the problems of abnormal noise generated when the user sucks due to a relatively fast liquid supply rate and the user being prone to sucking the liquid matrix.

[0101] In the above implementation, the material of the liquid guiding element 106 and the liquid storage medium 103a may be the same or different. The density of the liquid guiding element 106 is greater than the density of the liquid storage medium 103a. In this way, on the one hand, it can ensure that the liquid guiding element 106 can strongly suck the liquid matrix in the liquid channel, so that the liquid matrix in the liquid guiding element 106 can be smoothly transferred to the liquid storage medium 103a. On the other hand, through the liquid guiding element 106, the oversaturation of the liquid storage medium 103a can be slowed down, and the probability of liquid matrix leakage can be reduced. In other examples, the liquid guiding element 106 and the liquid storage medium 103a adopt the same fiber material, and both can play the role of sucking the liquid matrix from the liquid channel, that is, the through hole 108, and transferring it to the atomization core 104. The liquid guiding element 106 and the liquid storage medium 103a can be filled in the liquid storage cavity 103 as an integral liquid absorption element.

[0102] In the above embodiment, the liquid guiding element 106 is sleeved on the connecting pipe 105a, that is, the liquid guiding element 106 is arranged around the connecting pipe 105a. The liquid guiding element 106 is located between the liquid channel and the atomizing core 104. The inner diameter of the liquid guiding element 106 is larger than the outer diameter of the connecting pipe 105a, so that a spaced space is maintained between the inner surface of the liquid guiding element 106 and the outer surface of the connecting pipe 105a, and the liquid guiding element 106 is spaced from the atomizing core 104. In this way, when the second liquid matrix in the liquid storage cavity 202 flows through the liquid channel to the liquid storage cavity 103, it can be absorbed by the liquid guiding element 106 and transferred to the liquid storage medium 103a, and then indirectly transferred to the atomizing core 104. The liquid guiding element 106 can adjust or slow down the rate at which the liquid channel supplies the atomizing core 104, avoiding an excessive amount of liquid supplied to the atomizing core 104, which may cause abnormal noise in the atomizing core 104 during suction use; in addition, the liquid guiding element 106 does not directly contact the atomizing core 104, and at the same time, the liquid storage medium 103a only contacts a part of the atomizing core 104 (the liquid storage medium 103a only covers a part of the atomizing core 104 longitudinally or axially), avoiding the liquid absorbed by the atomizing core 104 from being too saturated, and can reduce the risk of the liquid matrix leaking from the liquid storage cavity 103 to the outside (for example, leaking to the circuit 106).

[0103] In the above embodiment, since the protruding portion 104a1 of the liquid guiding element 104a extends into the notch groove 105a2 of the connecting pipe 105a, it is thus exposed in the spaced space between the inner surface of the liquid guiding element 106 and the outer surface of the connecting pipe 105a, and the liquid matrix in the spaced space can be absorbed by the liquid guiding element 104a, thereby reducing the risk of the liquid matrix leaking from the liquid storage cavity 103 to the outside.

[0104] It should be noted that the above atomizing component 100 and the liquid storage component 200 are independent of each other. Before the atomizing component 100 and the liquid storage component 200 are connected (that is, before the housing assembly 101 and the housing assembly 201 are connected), the atomizing component 100 can be used alone and suctioned, and the atomizing core 104 only atomizes the first liquid matrix. After the atomizing component 100 and the liquid storage component 200 are connected (that is, after the housing assembly 101 and the housing assembly 201 are connected), the atomizing core 104 can atomize both the first liquid matrix and the second liquid matrix. In other examples, the atomizing component 100 can be combined with the power supply component 20 first, and then connected to the liquid storage component 200 for use.

[0105] It should be noted that in other examples, the number of the liquid storage components 200 can be multiple.

[0106] It should be noted that in other examples, before the housing assembly 201 is connected to the housing assembly 101, the electronic atomization device cannot be used and sucked. That is, only after the housing assembly 201 is connected to the housing assembly 101, the electronic atomization device can be used and sucked. At this time, the atomization core 104 can atomize both the first liquid matrix and the second liquid matrix.

[0107] The above-mentioned switch 209 is configured to be able to open the air passage and the liquid passage simultaneously or close the air passage and the liquid passage simultaneously based on the user's operation. When the switch 209 opens the air passage and the liquid passage, the air part of the liquid storage cavity 103 is communicated with the air part of the liquid storage cavity 202, so as to realize air exchange between the liquid storage cavity 103 and the liquid storage cavity 202. The second liquid matrix stored in the liquid storage cavity 202 can flow to the liquid storage cavity 103 through the liquid passage to timely supplement the consumed liquid matrix in the liquid storage cavity 103; when the switch 209 closes the air passage and the liquid passage, the air part of the liquid storage cavity 103 is not communicated with the air part of the liquid storage cavity 202, and the second liquid matrix stored in the liquid storage cavity 202 cannot flow to the liquid storage cavity 103 through the liquid passage.

[0108] In Figure 3 and Figure 4 In the examples, the switch 209 includes a manually operated switch 209. The manually operated switch 209 moves relative to the housing assembly 201 based on the user's manual operation. The stroke of this movement has a first position ( Figure 4 shown) for simultaneously opening the air passage and the liquid passage and a second position ( Figure 3 shown) for simultaneously closing the air passage and the liquid passage, that is, moving from the first position to the second position or returning from the second position to the first position relative to the housing assembly 201 based on the user's operation.

[0109] Specifically, the switch 209 includes an operating member 2091, a connecting member 2092, and a blocking member. The blocking member includes a first blocking member 2093 and a second blocking member 2094. The first blocking member 2093 is disposed in the connection channel 2052 or at least partially received in the connection channel 2052. One end of the operating member 2091 is fixed to the end of the first blocking member 2093 away from the liquid storage cavity 202 through the connecting member 2092, and the other end of the operating member 2091 extends out of the housing assembly 201, that is, is exposed outside the housing assembly 201, so as to receive the user's manual operation. The second blocking member 2094 is disposed in the liquid storage cavity 202. One end of the second blocking member 2094 is fixedly connected to the other end of the first blocking member 2093 close to the liquid storage cavity 202, and the other end of the second blocking member 2094 extends toward the through hole 2062.

[0110] In a preferred embodiment, at least a part of the interior of the first plugging member 2093 is hollow. Specifically, the first plugging member 2093 has a through-hole 2093a disposed near the through-hole 2051b, a through-hole 2093b disposed near the liquid storage chamber 202, and a liquid passage 2093c extending from the through-hole 2093a to the through-hole 2093b. The other end of the second plugging member 2094 has a convex post 2094a.

[0111] When the switch 209 moves to the second position where the air passage and the liquid passage are closed, the convex post 2094a of the second plugging member 2094 is inserted into the through-hole 2062, thereby plugging the through-hole 2062 and closing the air passage; the through-hole 2093a is misaligned with the through-hole 2051b, and the through-hole 2093b is hidden in the connection passage 2052, that is, not communicated with the liquid storage chamber 202 (the through-hole 2061 abuts against the first plugging member to form a seal), thereby plugging the through-hole 2051b and closing the liquid passage.

[0112] When the switch 209 moves to the first position where the air passage and the liquid passage are opened, the convex post 2094a of the second plugging member 2094 is removed from the through-hole 2062, thereby opening the through-hole 2062, that is, opening the air passage; the through-hole 2093a is aligned with the through-hole 2051b, the other end of the first plugging member 2093 extends into the liquid storage chamber 202, and the through-hole 2093b is exposed from the connection passage 2052 to the liquid storage chamber 202, that is, communicated with the liquid storage chamber 202, thereby opening the through-hole 2051b, that is, opening the liquid passage. At this time, the second liquid matrix stored in the liquid storage chamber 202 can flow into the through-hole 2051b through the through-hole 2093b, the liquid passage 2093c, and the through-hole 2093a in sequence.

[0113] When the switch 209 opens the air passage and the liquid passage, the second liquid matrix stored in the liquid storage chamber 202 can flow into the liquid storage chamber 103 through the through-hole 2093b, the liquid passage 2093c, the through-hole 2093a, the through-hole 2051b, and the through-hole 108 in sequence, so as to timely supplement the consumed liquid matrix to the liquid storage chamber 103; a part of the air in the liquid storage chamber 202 can realize air exchange with a part of the air in the liquid storage chamber 103 through the through-hole 2062, the through-hole 2051a, the through-hole 2071, and the through-hole 108 in sequence.

[0114] The user can operate the other end of the operating member 2091 to move the switch 209 relative to the housing assembly 201 to the first position where the air passage and the liquid passage are opened ( Figure 4 as shown) or the second position where the air passage and the liquid passage are closed ( Figure 3As shown. For example, it is assumed that before leaving the factory, the liquid storage component 200 and the atomization component 100 have been assembled, and the initial position of the switch 209 is the second position that closes the air passage and the liquid passage. When the user pinches the other end of the operating member 2091 and moves it towards the nozzle side or axially or longitudinally upwards, the operating member 2091 drives the first plugging member 2093 and the second plugging member 2094 to move towards the nozzle side, so that the convex column 2094a of the second plugging member 2094 is removed from the through hole 2062, the through hole 2093a is aligned with the through hole 2051b, and the through hole 2093b is exposed from the connection passage 2052 to the liquid storage cavity 202, and the switch 209 moves from the second position to the first position; when the user pinches the other end of the operating member 2091 and moves it towards the side away from the nozzle or axially or longitudinally downwards, the operating member 2091 drives the first plugging member 2093 and the second plugging member 2094 to move towards the side away from the nozzle, so that the convex column 2094a of the second plugging member 2094 is inserted into the through hole 2062, the through hole 2093a is misaligned with the through hole 2051b, and the through hole 2093b is hidden in the connection passage 2052, and the switch 209 moves from the first position to the second position. It can be understood that it is also feasible that the initial position of the switch 209 is the first position that opens the air passage and the liquid passage, and the operation process is similar to the above.

[0115] In an example, the housing assembly 101 is further provided with a notch groove 101c. Through the notch groove 101c, on the one hand, the axial movement stroke of the operating member 2091 or the switch 209 can be increased, and on the other hand, the housing assembly 101 and the housing assembly 201 can limit the operating member 2091, so as to achieve the effect of in-place operation. That is, when the switch 209 moves to the first position that opens the air passage and the liquid passage, the housing assembly 201 can limit the operating member 2091; when the switch 209 moves to the second position that closes the air passage and the liquid passage, the housing assembly 101 can limit the operating member 2091.

[0116] In one example, the switch 209 further includes a seal 2095 and a seal 2096. Both the seal 2095 and the seal 2096 are annular and sleeved on the first plugging member 2093. The seal 2095 is located above the through hole 2093a, and the seal 2096 is located below the through hole 2093a, that is, the through hole 2093a is provided between the seal 2095 and the seal 2096. After assembly, both the seal 2095 and the seal 2096 are in contact with the inner surface of the wall that defines the connection channel 2052, thereby forming a seal. In this way, when the switch 209 opens the air channel and the liquid channel, the seal 2095 is located above the through hole 2093a and the through hole 2051b, and the seal 2096 is located below the through hole 2093a and the through hole 2051b. When the liquid matrix passes through the liquid channel, it can prevent the liquid matrix from leaking outside the housing assembly 201. When the switch 209 closes the air channel and the liquid channel, both the seal 2095 and the seal 2096 are located below the through hole 2051b, which can prevent the liquid matrix in the through hole 2051b from leaking outside the housing assembly 201. On the other hand, the seal 2095 and the seal 2096 can increase the friction between the first plugging member 2093 and the wall that defines the connection channel 2052. When the switch 209 moves to the first position where the air channel and the liquid channel are opened, the switch 209 can be kept in the first position.

[0117] It should be noted that in the above examples, the switch is a manually operated switch. In other examples, the switch is an electrically operated switch, which is also feasible to simultaneously open the air passage and the liquid passage or simultaneously close the air passage and the liquid passage under electric operation. For example, when it is detected that the liquid matrix in the liquid storage cavity 103 is less, the liquid passage can be electrically operated to open, so that the second liquid matrix stored in the liquid storage cavity 202 can flow through the liquid passage to the liquid storage cavity 103 to timely supplement the consumed liquid matrix in the liquid storage cavity 103. Also for example, in some examples, when it is detected that the housing assembly 201 is connected to the housing assembly 101, the liquid passage can be electrically operated to open, so that the second liquid matrix stored in the liquid storage cavity 202 can flow through the liquid passage to the liquid storage cavity 103. In other examples, when the housing assembly 201 is connected to the housing assembly 101, the on-off state or the position of the switch 209 is changed by the structural interference at the assembly position of the two, so that the first passage and the second passage between the liquid storage cavity 202 and the liquid storage cavity 103 are simultaneously conducted. When the housing assembly 201 is removed from the housing assembly 101, the switch 209 can be restored to the closed state to re-close the first passage and the second passage. In other examples, the switch 209 is exposed at one end where the atomizing assembly 10 is connected to the power supply assembly 20. When the end of the atomizing assembly 10 is received in the receiving cavity 21 of the power supply assembly 20, the power supply assembly 20 can push the switch 209 to move to the open state, so that the first passage and the second passage between the liquid storage cavity 202 and the liquid storage cavity 103 are simultaneously conducted.

[0118] It should be noted that in the above examples, the switch is provided on the housing assembly 201, while in other examples, it is also feasible to provide the switch on the housing assembly 101. For example, by the switch provided on the housing assembly 101, the through hole 107 and the through hole 108 are simultaneously opened, or the through hole 107 and the through hole 108 are simultaneously closed.

[0119] It should be noted that in the above examples, the setting of the switch is not limited to Figure 12 the described situation. For example, in other examples, the bracket 205 does not have the connecting passage 2052, the through hole 2051b is directly communicated with the liquid storage cavity 202 through the through hole 2061, and the second plugging member 2094 of the switch is located above the through hole 2061 and the through hole 2062; when the switch 209 moves to the second position to close the air passage and the liquid passage, the second plugging member 2094 can directly plug the through hole 2061 and the through hole 2062, so as to simultaneously close the air passage and the liquid passage; conversely, the air passage and the liquid passage are simultaneously opened.

[0120] It should be noted that the description and drawings of this application provide preferred embodiments of this application.

Moreover, the above technical features continue to be combined with each other to form various embodiments not listed above, which are all regarded as within the scope described in the specification of this application; further, for those of ordinary skill in the art, improvements or transformations can be made according to the above description, and all such improvements and transformations should fall within the protection scope of the appended claims of this application.
