Description

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

[0003] Due to various factors, such as cost, regulations, etc., the amount of liquid matrix stored inside the atomizer is generally small. When the liquid matrix is ​​consumed, it can be continued to be used by filling it with liquid, replacing the atomizer, etc., or it can be directly discarded. On the one hand, the above method brings inconvenience to the user and reduces the user's experience, and on the other hand, it increases the user's cost of use. An existing electronic atomization device can replenish the liquid matrix to the electronic atomization device through a larger capacity liquid storage component, thereby reducing the user's cost of use and improving the user's experience. However, the problem with this device is that the rate at which the liquid storage component replenishes the liquid matrix to the electronic atomization device is uncontrollable, and it is easy to have a fast liquid conduction rate and abnormal noise during suction.

[0060] In order to facilitate the understanding of the present application, the present application is described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or there can be one or more centered elements therebetween. When an element is described as "connected to" another element, it can be directly connected to the other element, or there can be one or more centered elements therebetween.

[0062] As used herein, the terms 'upstream' and 'downstream' describe the relative positions of components, or parts of components, in the electronic atomization device in the direction of the flow of the suction airflow.

[0063] like Figure 1-Figure 5 As shown, the electronic atomization device 100 provided in one embodiment of the present application includes a shell assembly 101. The shell assembly 101 can be composed of multiple components, such as a main shell, a top cover arranged at the top end of the main shell, and a bottom cover arranged at the bottom end of the main shell. The shell assembly 101 can also be formed in one piece.

[0064] A nozzle 102 is provided at the top of the housing assembly 101. The nozzle 102 and the housing assembly 101 may be formed integrally or separately. The nozzle 102 is used for the user to inhale the aerosol generated by atomization.

[0065] The housing assembly 101 is formed with a liquid storage chamber 103 that is used to store the first liquid matrix. The first liquid matrix can be a liquid that comprises a tobacco-containing substance that contains volatile tobacco flavor components, or can be a liquid that comprises non-tobacco substances. For example, the liquid matrix can comprise water, solvent, ethanol, plant extract, spices, flavoring agent or vitamin mixture.

Flavoring agent can comprise the composition that can provide multiple fragrance or local flavor to the user. Vitamin mixture can be a material that is mixed with at least a among vitamin A, vitamin B, vitamin C and the vitamin E, but are not limited to this. In addition, the first liquid matrix can comprise an aerosol forming agent such as glycerine and propylene glycol.

[0066] A liquid storage medium 103a is provided in the liquid storage chamber 103, a sealing member 103b is provided at the upper end of the liquid storage chamber 103, and a sealing member 103c is provided at the lower end of the liquid storage chamber 103. The upper and lower ends of the liquid storage chamber 103 are sealed by the sealing members 103b and 103c.

[0067] The liquid storage medium 103a is made of, for example, a fiber material or a porous material. Figure 6 As shown, the liquid storage medium 103a is generally tubular in structure. The liquid storage medium 103a can absorb and hold the first liquid matrix and provide the first liquid matrix to the atomization assembly 104. When the liquid storage medium 103a reaches a saturated state after injection, the content of the liquid matrix in the liquid storage medium 103a is between 0.1ml and 2ml, such as 0.5ml, 0.8ml, 1ml, 1.5ml or 2ml, etc. The partial space between the end surface of the liquid storage medium 103a and the sealing member 103b defines an air portion.

[0068] An atomizing assembly 104 is disposed in the housing assembly 101 , and the atomizing assembly 104 is used to atomize a liquid matrix to generate an aerosol.

[0069] like Figure 7 As shown, the atomization assembly 104 includes a liquid guiding element 104a and a heating element 104b. The liquid guiding element 104a can absorb the liquid matrix in the liquid storage medium 103a and transfer the liquid matrix to the heating element 104b, and the heating element 104b can be heated by supplying electric current and transfer heat to the liquid matrix in contact with the heating element 104b to heat the liquid matrix, thereby generating an aerosol.

[0070] The liquid-conducting element 104a is configured as a tubular structure, and it is understood that it can also be a plate-like structure or other regular or irregular shapes. The liquid-conducting element 104a can be made of a flexible fiber material, such as cotton fiber, non-woven fabric or sponge. Alternatively, in other examples, the liquid-conducting element 104a can also be a rigid porous body, such as porous ceramics, porous glass, etc. The outer surface of the liquid-conducting element 104a has a radially outward protrusion 104a1.

[0071] The heating element 104b is arranged near the inner surface of the liquid-conducting element 104a, and can be abutted against the inner surface of the liquid-conducting element 104a, or partially or completely embedded in the liquid-conducting element 104a. The heating element 104b can be a resistive heating mesh, a resistive heating coil, etc. The heating element 104b 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 one example, the heating element 104b can be wound by a sheet or mesh substrate, and 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 electronic atomization device 100. Conductive pins 104c and conductive pins 104d are welded or arranged at both ends of the heating element 104b to guide current on the heating element 104b. In other examples, the heating element 104b can be arranged as a structure wound around the liquid-conducting element 104a.

[0072] The housing assembly 101 is also provided with an air flow channel 105 to transmit the aerosol generated by the atomization assembly 104 to the mouthpiece 102 for inhalation by the user. The lower end of the air flow channel 105 is connected to the air inlet, which can be arranged on the side wall of the housing assembly 101; the upper end of the air flow channel 105 is connected to the mouthpiece 102, that is, connected to the air outlet (the dotted arrow in the figure indicates the air flow direction in the air flow channel 105).

[0073] like Figure 8 As shown, a connecting tube 105a is provided in the housing assembly 101, and the hollow portion inside the connecting tube 105a defines a portion of the air flow channel 105. The connecting tube 105a extends along the axial direction of the liquid storage chamber 103. The upper end of the connecting tube 105a is connected to the sealing member 103b, and the lower end of the connecting tube 105a is connected to the sealing member 103c. The connecting tube 105a is preferably made of a thinner rigid material, such as glass fiber material, stainless steel, etc.

[0074] In a preferred embodiment, the liquid storage medium 103a is sleeved on the connecting tube 105a; the inner diameter of the liquid storage medium 103a is slightly smaller than the outer diameter of the connecting tube 105a, so that the liquid storage medium 103a is tightly sleeved on the connecting tube 105a. The atomizing assembly 104 is arranged in the connecting tube 105a. The atomizing assembly 104 and the connecting tube 105a are coaxially arranged. The side wall of the connecting tube 105a also has a liquid guide port 105a1 arranged near the lower end of the connecting tube 105a, and the liquid storage medium 103a covers the liquid guide port 105a1. A portion of the liquid guide element 104a is exposed to the liquid storage cavity 103 through the liquid guide port 105a1, so that the portion of the liquid guide element 104a is arranged close to the liquid storage medium 103a or keeps contact with the liquid storage medium 103a, so that the liquid matrix in the liquid storage cavity 103 flows into the atomization component 104 through the liquid guide port 105a1, that is, it is sucked by the liquid guide element 104a and atomized by the heating element 104b to generate an inhalable aerosol.

[0075] A notch 105a2 is also provided on the side wall of the connecting tube 105a, and the notch 105a2 extends from the lower end of the connecting tube 105a toward the upper end of the connecting tube 105a. The protruding portion 104a1 of the liquid-conducting element 104a extends into the notch 105a2, thereby being exposed in the liquid storage chamber 103. After assembly, the liquid storage medium 103a maintains contact with a portion of the protruding portion 104a1, thereby facilitating the liquid-conducting element 104a to absorb the liquid matrix.

[0076] A circuit 106 is also provided in the housing assembly 101, and the circuit 106 can control the overall operation of the electronic atomization device 100. In detail, the circuit 106 not only controls the operation of the battery cell 107 and the atomization assembly 104, but also controls the operation of other components in the electronic atomization device 100. In addition, the circuit 106 can determine whether the electronic atomization device 100 can be operated by checking the status of the components of the electronic atomization device 100.

[0077] The circuit 106 includes at least one controller. The controller may include a logic gate array, or may include a combination of a general-purpose microprocessor and a memory storing a program executable in the microprocessor. In addition, those skilled in the art will appreciate that the circuit 106 may include another type of hardware.

[0078] The battery cell 107 provides power for operating the electronic atomization device 100. For example, the battery cell 107 can provide power to heat the heating element and can provide power required to operate the circuit 106. In addition, the battery cell 107 can provide power required to operate other components provided in the electronic atomization device 100.

[0079] The battery cell 107 may be, but is not limited to, a lithium iron phosphate (LiFePO4) battery. For example, the battery cell 107 may be a lithium cobalt oxide (LiCoO2) battery or a lithium titanate battery. The battery cell 107 may be a rechargeable battery or a disposable battery.

[0080] It should be noted that the figure only shows the components related to this embodiment. A person skilled in the art should understand that the electronic atomization device 100 may also include Figure 1-Figure 5 Other common components other than the components shown. For example, a puff detector 112 may also be provided in the housing assembly 101, which is used to detect the user's puffing action and generate a corresponding electrical signal, that is, to detect whether the electronic atomization device 100 is puffed, so that the circuit 106, such as a controller, controls the operation of the battery cell 107, the heating element, etc. according to the electrical signal, for example, controls the battery cell 107 to provide power to the heating element, so that the heating element heats the atomized liquid matrix. The puff detector 112 can adopt common pressure sensors, differential pressure sensors, airflow sensors, etc. The puff detector 112 is connected to the airflow channel 105, so that when the user puffs, the change of the puff airflow can be sensed.

[0081] It should also be noted that Figure 1-Figure 5 In the example, the above components are formed in one piece, and the electronic atomization device 100 is a common one-piece device. In other examples, the electronic atomization device includes an atomizer and a power supply assembly detachably connected to the atomizer, the atomizer is usually also called a cigarette cartridge, and the power supply assembly is usually also called a cigarette rod; wherein the circuit 106, the battery cell 107, and the puff detector are in the power supply assembly; the nozzle 102, the liquid storage chamber 103, and the atomization assembly 104 are in the atomizer, which is also feasible.

[0082] Please combine Figure 10-13 It is understood that the liquid storage component 200 provided in one embodiment of the present application includes a housing assembly 201, and the housing assembly 201 can be composed of multiple components, such as a main body 201a, a bottom cover 201b, a sealing member 201c and a sealing member 201d.

[0083] The main body 201a is connected to the bottom cover 201b. In a preferred embodiment, the main body 201a is detachably connected to the bottom cover 201b, such as a snap connection. A portion of the bottom cover 201b extends into the main body 201a. The main body 201a and the bottom cover 201b together define a liquid storage chamber 202 for storing a second liquid matrix. In a further embodiment, the bottom cover 201b is provided with a liquid injection port 201b1, through which the second liquid matrix can be injected into the liquid storage chamber 202; the liquid injection port 201b1 can be sealed by a sealing member, or sealed by other means, which is not limited in this application. The sealing member 201c is arranged between the bottom cover 201b and the main body 201a to prevent the second liquid matrix from leaking from the gap between the bottom cover 201b and the main body 201a. In a preferred embodiment, a groove 201b2 is provided on the outer surface of the bottom cover 201b, and the sealing member 201c is annular and at least partially received in the groove 201b2, thereby achieving sealing between the bottom cover 201b and the main body 201a.

[0084] Similar to the first liquid matrix, the second liquid matrix can be the liquid that comprises the tobacco-containing material that contains volatile tobacco flavor component, can also be the liquid that comprises non-tobacco material.For example, the liquid matrix can comprise water, solvent, ethanol, plant extract, spices, flavoring agent or vitamin mixture.Spice can comprise menthol, European mint, spearmint oil, various fruity fragrance components etc., but is not limited to this.Flavoring agent can comprise the composition that can provide multiple fragrance or local flavor to the user.Vitamin mixture can be for being mixed with at least a material in vitamin A, vitamin B, vitamin C and the vitamin E, but is not limited to this.In addition, the second liquid matrix can comprise the aerosol forming agent as glycerine and propylene glycol.

[0085] It should be noted that the composition or characteristics of the second liquid matrix and the first liquid matrix may be different or the same. For example, in some examples, the second liquid matrix and the first liquid matrix have different components, or the concentration of the second liquid matrix and the first liquid matrix are different. For example, in other examples, the second liquid matrix and the first liquid matrix have exactly the same composition, the second liquid matrix can be part of a certain liquid formula, and the first liquid matrix can be another part of a certain liquid formula. The second liquid matrix can be introduced into the liquid storage chamber 103 as a supplementary source of the first liquid matrix, thereby increasing the number of puffs of the electronic atomization device.

[0086] The volume of the liquid storage chamber 202 is larger than that of the liquid storage chamber 103. Generally, the volume of the second liquid matrix stored in the liquid storage chamber 202 is between 2ml and 10ml, such as 2ml, 4ml, 5ml, 6ml, 8ml, 10ml, etc. It can be understood that the volume of the liquid storage chamber 202 is slightly larger than the volume of the stored second liquid matrix. In this way, after the liquid storage chamber 202 stores the second liquid matrix, it can be divided into two parts, one part is the air part, and the other part is the liquid matrix part. Usually, the liquid storage medium 103a is not set in the liquid storage chamber 202.

[0087] The liquid storage component 200 is independent of the main part of the electronic atomization device 100. For example, when the product is in a packaged state or unused state, the liquid storage component 200 is separated from the main part of the electronic atomization device 100, that is, the shell component 101. The user can assemble the liquid storage component 200 on the shell component 101 before use. In one example, the liquid storage component 200 is detachably connected to the electronic atomization device 100, that is, the shell component 201 is detachably connected to the shell component 101, such as a snap connection, a magnetic connection, etc. In one example, once the liquid storage component 200 is connected to the electronic atomization device 100, it cannot be disassembled again.

[0088] The housing assembly 101 is also provided with a receiving cavity 108 for receiving or accommodating at least part of the housing assembly 201. Specifically, the shape of the receiving cavity 108 is adapted to the shape of the housing assembly 201, and the receiving cavity 108 is a notch groove that penetrates part of the left side wall and part of the top wall of the housing assembly 101, and the housing assembly 201 can be assembled to or retained on the housing assembly 101 from the left side of the housing assembly 101. The inner wall of the receiving cavity 108 is provided with a card slot 108a, and the outer wall of the housing assembly 201 is provided with a snap connector (not shown), and the snap connection between the housing assembly 201 and the housing assembly 101 is realized by the cooperation of the card slot 108a and the snap connector. After the housing assembly 201 is connected to the housing assembly 101, they jointly define the outer shell of the electronic atomization device 100. It can be understood that the connection method between the housing assembly 201 and the housing assembly 101 is not limited to the above situation.

[0089] When the housing assembly 201 is connected to the housing assembly 101, the liquid storage chamber 103 and the liquid storage chamber 202 are arranged in sequence approximately along the width direction of the electronic atomization device 100. The liquid storage chamber 103 is arranged near the right end of the electronic atomization device 100, and the liquid storage chamber 202 is arranged near the left end of the electronic atomization device 100. It can be understood that the arrangement of the liquid storage chamber 103 and the liquid storage chamber 202 is not limited to the above situation.

[0090] When the housing assembly 201 is connected to the housing assembly 101 , the air portion of the liquid storage chamber 103 is connected to the air portion of the liquid storage chamber 202 , and the liquid matrix of the liquid storage chamber 202 can be replenished into the liquid storage chamber 103 in a timely manner.

[0091] Specifically, the housing assembly 101 further includes a through hole 109 and a through hole 110 that are arranged at intervals. One end of the through hole 109 is in communication with the liquid storage chamber 103, and the other end of the through hole 109 protrudes from the right side wall of the receiving chamber 108 and is in communication with the outside of the housing assembly 101; one end of the through hole 110 is in communication with the liquid storage chamber 103, and the other end of the through hole 110 protrudes from the right side wall of the receiving chamber 108 and is in communication with the outside of the housing assembly 101. The liquid matrix can be added to the liquid storage chamber 103 through the through hole 109, and the air can be added or discharged from the liquid storage chamber 103 through the through hole 110. The through hole 109 can be arranged close to the through hole 110, for example, the through hole 109 is arranged next to the through hole 110; the through hole 109 and the through hole 110 can also be arranged at a certain distance. In some examples, the advantage of the through hole 109 being arranged close to the through hole 110 is that the same sealing member can be used to realize the connection between the through hole 109, the through hole 110 and the liquid storage assembly, thereby improving the sealing reliability.

[0092] In a specific implementation, one end of the through hole 110 can be connected to the air part of the liquid storage chamber 103 through the gap between the liquid storage medium 103a and the wall defining the liquid storage chamber 103. For example, the liquid storage medium 103a has a notch groove 103a1, and a gap is formed between the notch groove 103a1 and the wall defining the liquid storage chamber 103, thereby allowing the through hole 110 to communicate with the air part of the liquid storage chamber 103; or, the liquid storage medium 103a has an air vent, and the through hole 110 is connected to the air part of the liquid storage chamber 103 through the air vent.

[0093] In one example, the external air can also communicate with the air portion of the liquid storage chamber 103 through the gap between the connecting tube 105a and the sealing member 103c.

[0094] When the housing component 201 is not connected to the housing component 101 , the through hole 109 or the through hole 110 may be sealed by a sealing member, such as a removable silicone plug or silicone cap, or may be sealed by a pierceable film.

[0095] The bottom cover 201b is also provided with a receiving chamber 201b3, a through hole 201b4 and a through hole 201b5. The receiving chamber 201b3 is in communication with the outside of the housing assembly 201. One end of the through hole 201b4 is arranged near the bottom of the liquid storage chamber 202 and is in communication with the liquid storage chamber 202, and the other end of the through hole 201b4 is in communication with the receiving chamber 201b3; in a further implementation, the bottom of the liquid storage chamber 202 is also provided with an inclined portion 201b6 inclined toward one end of the through hole 201b4, and the inclined portion 201b6 is used to guide the liquid matrix to flow toward one end of the through hole 201b4 without accumulating at the bottom of the liquid storage chamber 202, thereby improving the utilization rate of the liquid matrix. The through hole 201b5 is arranged at intervals from the through hole 201b4, and the through hole 201b5 can be adjacent to the through hole 201b4, or can be at a certain distance from the through hole 201b4; the through hole 201b5 can replenish or discharge air into the liquid storage chamber 202. One end of the wall defining the through hole 201b5 extends into the liquid storage chamber 202 and is disposed close to the top of the liquid storage chamber 202, thereby facilitating direct communication with the air portion of the liquid storage chamber 202, and the other end of the through hole 201b5 is communicated with the accommodating chamber 201b3.

[0096] The sealing member 201d is at least partially received in the receiving chamber 201b3. The sealing member 201d is provided with a receiving chamber 201d1, a through hole 201d2 and a through hole 201d3. The receiving chamber 201d1 is communicated with the outside of the housing assembly 201. One end of the through hole 201d2 is arranged on the left side wall of the sealing member 201d, and the other end of the through hole 201d2 is communicated with the receiving chamber 201d1. One end of the through hole 201d3 is arranged on the top wall of the sealing member 201d, and the other end of the through hole 201d3 is communicated with the receiving chamber 201d1.

[0097] like Figure 4 As shown, when the housing assembly 201 is not connected to the housing assembly 101, the other end of the through hole 201b4 or at least part of the wall defining the through hole 201b4 extends into the through hole 201d2, so that the through hole 201b4 is connected to the through hole 201d2; and the other end of the through hole 201b5 is misaligned with one end of the through hole 201d3, so that the through hole 201b5 is not connected to the through hole 201d3, that is, the other end of the through hole 201b5 is closed by the sealing member 201d, so as to close the through hole 201b5. At this time, the through hole 201d2 and / or the through hole 201d3 can be blocked by other sealing members, such as by a removable silicone plug or silicone cap, or by a pierceable film member. Since the through hole 201b5 is blocked by the sealing member 201d, at this time, the through hole 201b5 can also be considered not to be blocked by other sealing members.

[0098] When the shell component 201 is assembled onto the shell component 101 from the left side of the shell component 101, at least part of the wall defining the through hole 109 and the through hole 110 extends into or is accommodated in the accommodating cavity 201b3, thereby abutting against the sealing member, and the through hole 109 is connected with the through hole 201d2, and the through hole 110 is connected with the through hole 201d3, thereby making the through hole 109 connected with the through hole 201b4. Since the through hole 201b5 is blocked by the sealing member 201d, the through hole 110 and the through hole 201b5 are not connected in the initial connection state.

[0099] When the housing assembly 201 is further assembled onto the housing assembly 101 from the left side of the housing assembly 101, the sealing member 201d is squeezed or pushed by the wall defining the through hole 109 and the through hole 110, and is driven to move into the receiving chamber 201b3 (at this time, the wall defining the through hole 201b4 moves in the through hole 201d2). When the sealing member 201d moves a certain distance into the receiving chamber 201b3 or moves to a position, for example, when the end of the wall defining the through hole 201d2 abuts against the bottom of the receiving chamber 201b3, the other end of the through hole 201b5 is aligned with one end of the through hole 201d3, so that the through hole 201b5 is connected with the through hole 201d3, and then the through hole 110 is connected with the through hole 201b5, that is, the through hole 201b5 is opened (first position). The other end of the through hole 201b4 or at least part of the wall defining the through hole 201b4 moves in the through hole 201d2. In this way, the air portion of the liquid storage chamber 103 is connected to the air portion of the liquid storage chamber 202 , and the liquid matrix of the liquid storage chamber 202 can be replenished into the liquid storage chamber 103 in a timely manner.

[0100] In this case, the through hole 201b4, the through hole 201d2 and the through hole 109 together define a liquid channel (first channel), thereby providing a fluid path between the liquid storage chamber 103 and the liquid storage chamber 202 that enables the first liquid matrix and / or the second liquid matrix to flow. One end of the liquid channel is in communication with the liquid storage chamber 103, and the other end of the liquid channel is in communication with the liquid storage chamber 202. The through hole 201b5, the through hole 201d3 and the through hole 110 together define an air channel (second channel), which is used to provide an air path for air exchange between the liquid storage chamber 103 and the liquid storage chamber 202. One end of the air channel is in communication with the air portion of the liquid storage chamber 103, and the other end of the air channel is in communication with the air portion of the liquid storage chamber 202. 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 flow smoothly to the liquid storage chamber 103 through the liquid channel, and the consumed liquid matrix is ​​replenished to the liquid storage chamber 103 in time, so as to avoid the negative pressure generated by the reduction of the liquid matrix in the liquid storage chamber 103 from preventing the remaining liquid matrix from further flowing into the liquid storage chamber 202. In an example, it can be known from the above that the external air can also communicate with the air part of the liquid storage chamber 103 through the gap between the connecting tube 105a and the sealing member 103c. Therefore, the external air can also achieve air exchange with the air part of the liquid storage chamber 103 and / or the liquid storage chamber 202.

[0101] In a further implementation, a liquid conducting element 111 is further provided in the liquid storage chamber 103. Fig. 9 As shown, the liquid-conducting element 111 is generally in a tubular structure. The liquid-conducting element 111 and the liquid storage medium 103a are arranged in sequence along the axial direction of the liquid storage chamber 103. The liquid-conducting element 111 is arranged close to the through hole 109 and the through hole 110, that is, the liquid-conducting element 111 is connected to the liquid channel, and the through hole 109 and the through hole 110 are both covered by the liquid-conducting element 111. The upper surface of the liquid-conducting element 111 is in contact with the lower surface of the liquid storage medium 103a, the lower surface of the liquid-conducting element 111 is in contact with the bottom of the liquid storage chamber 103, and the outer surface of the liquid-conducting element 111 is in contact with the wall defining the liquid storage chamber 103. In this way, when the second liquid matrix in the liquid storage chamber 202 flows to the liquid storage chamber 103 through the liquid channel, it can be sucked by the liquid guide element 111 and transferred to the liquid storage medium 103a, and then indirectly transferred to the liquid guide element 104a in the atomizer assembly 104, that is, sucked by the liquid guide element 104a in the atomizer assembly 104. Such a configuration can make the second liquid matrix stored in the liquid storage chamber 202 flow to the atomizer assembly 104 more smoothly, avoiding the problem of abnormal noise generated when the user inhales due to the fast liquid supply rate and the problem that the user easily inhales the liquid matrix.

[0102] In the above implementation, the material of the liquid-conducting element 111 can be the same as or different from that of the liquid storage medium 103a. The density of the liquid-conducting element 111 is greater than that of the liquid storage medium 103a. In this way, on the one hand, it can be ensured that the liquid-conducting element 111 can strongly absorb the liquid matrix in the liquid channel, so that the liquid matrix in the liquid-conducting element 111 is smoothly transferred to the liquid storage medium 103a. On the other hand, the liquid-conducting element 111 can slow down the oversaturation of the liquid storage medium 103a, reducing the probability of liquid matrix leakage.

[0103] In the above implementation, since the outer surface of the liquid-conducting element 111 maintains contact with the wall defining the liquid storage chamber 103, in order to avoid the air channel from being blocked, there can be a certain gap between the wall defining the liquid storage chamber 103 and the outer surface of the liquid-conducting element 111, so that air can pass through the gap between the wall defining the liquid storage chamber 103 and the outer surface of the liquid-conducting element 111, flow to the notch groove 103a1, and then communicate with the air part of the liquid storage chamber 103 to achieve air exchange.

[0104] In the above implementation, the liquid guiding element 111 is sleeved on the connecting tube 105a, that is, the liquid guiding element 111 is arranged around the connecting tube 105a. The liquid guiding element 111 is located between the liquid channel and the atomizing assembly 104. The inner diameter of the liquid guiding element 111 is larger than the outer diameter of the connecting tube 105a, so that the inner surface of the liquid guiding element 111 and the outer surface of the connecting tube 105a are kept separated by a space. In this way, when the second liquid matrix in the liquid storage chamber 202 flows to the liquid storage chamber 103 through the liquid channel, it can be absorbed by the liquid guiding element 111 and transferred to the liquid storage medium 103a, thereby indirectly transferred to the atomizing assembly 104. In this way, the liquid guiding element 111 can adjust or slow down the rate at which the liquid channel supplies the atomizer assembly 104, thereby avoiding excessive liquid supply to the atomizer assembly 104, thereby causing the atomizer assembly 104 to produce abnormal noise during suction use; in addition, the liquid guiding element 111 does not directly contact the atomizer assembly 104, and the liquid storage medium 103a only partially contacts the atomizer assembly 104 (the liquid storage medium 103a only covers a portion of the atomizer assembly 104 in the longitudinal or axial direction), thereby avoiding the atomizer assembly 104 from saturating with liquid, and reducing the risk of the liquid matrix leaking from the liquid storage chamber 103 to the outside (for example, leaking to the circuit 106).

[0105] In the above implementation, the axial distance between the bottom of the liquid storage chamber 103 and the liquid guide port 105a1 of the connecting tube 105a is greater than the axial distance between the bottom of the liquid storage chamber 103 and the lower surface of the liquid storage medium 103a, or the axial distance between the bottom of the liquid storage chamber 103 and the liquid guide port 105a1 of the connecting tube 105a is greater than the axial distance between the upper and lower surfaces of the liquid guide element 111. In this way, when the second liquid matrix in the liquid storage chamber 202 flows to the liquid storage chamber 103 through the liquid channel, it will not be directly absorbed by the liquid guide element 104a in the atomizing assembly 104 through the liquid guide port 105a1. That is, it is helpful to slow down the speed of the liquid matrix to the liquid guide element 104a.

[0106] In the above implementation, since the protruding portion 104a1 of the liquid-conducting element 104a extends into the notch groove 105a2 of the connecting tube 105a and is exposed in the interval space between the inner surface of the liquid-conducting element 111 and the outer surface of the connecting tube 105a, the liquid matrix in the interval space can be absorbed by the liquid-conducting element 104a, thereby reducing the risk of the liquid matrix leaking from the liquid storage chamber 103 to the outside.

[0107] In a further implementation, since the liquid matrix in the liquid storage chamber 202 may flow into the through hole 201b5 (for example, during the injection process, or during the inversion process, etc.), during the process of assembling the housing assembly 201 to the housing assembly 101, the sealing member 201d can be pushed from the starting position (refer to Figure 4 The seal 201d position shown) moves to the end position (reference Figure 3 The sealing member 201d is positioned as shown in the figure, and the space of the receiving chamber 201b3 is compressed. At this time, the gas in the compressed space can be discharged toward the through hole 201b5 through the gap between the sealing member 201d and the receiving chamber 201b3, thereby discharging the liquid matrix in the through hole 201b5 back to the liquid storage chamber 202, thereby avoiding the blockage of the air passage by the liquid matrix. The gap between the sealing member 201d and the receiving chamber 201b3 can be at least partially defined by an exhaust groove 201d4 arranged on the outer surface of the sealing member 201d. One end of the exhaust groove 201d4 is arranged close to the through hole 201d3, and the other end extends to the left side wall of the sealing member 201d.

[0108] In some examples, during the process of the seal 201d moving from the starting position to the ending position, the air passage between the two liquid storage chambers is closed, and the liquid passage between the two is always connected. That is to say, during the process of the seal 201d being pushed until the through hole 201b5 and the through hole 201d3 are connected to each other, the space of the receiving chamber 201b3 can be continuously compressed, thereby increasing the air pressure inside the liquid storage chamber 202, which is beneficial for forcing the liquid matrix in the liquid storage chamber 202 to transfer to the liquid storage chamber 103.

[0109] In a further implementation, a plurality of convex portions 201d5 are further provided on the outer surface of the sealing member 201d, and the convex portions 201d5 abut against the inner surface of the liquid storage chamber 202, thereby forming a good sealing effect. Fig.11 or Fig.12 It can be seen that there is at least one protrusion 201d5 between one end of the exhaust groove 201d4 and the through hole 201d3; thus, when the other end of the through hole 201b5 is aligned with one end of the through hole 201d3, the exhaust groove 201d4 can be separated from the through hole 201b5 by the at least one protrusion 201d5, thereby ensuring the air tightness of the air passage.

[0110] It should be noted that, in the above example, the through hole 109 and the through hole 110 are arranged closely, and the through hole 201b4 and the through hole 201b5 corresponding thereto are also arranged closely, and the above function is achieved by a separate sealing member 201d. In other examples, the through hole 109 and the through hole 110 are arranged at a certain distance, and the through hole 201b4 and the through hole 201b5 corresponding thereto are also arranged at a certain distance, and the above function is achieved by two independent sealing members, which is also feasible.

[0111] It should be noted that the main body and the liquid storage component 200 of the above-mentioned electronic atomization device 100 are independent of each other. Before the main body and the liquid storage component 200 of the electronic atomization device 100 are not connected (that is, before the shell component 101 is not connected to the shell component 201), the main body can be used alone and sucked, and the atomization component 104 only atomizes the first liquid matrix. After the main body and the liquid storage component 200 are connected (that is, after the shell component 101 is connected to the shell component 201), the atomization component 104 can atomize both the first liquid matrix and the second liquid matrix. The combination of the main body and the liquid storage component 200 can also be collectively referred to as an electronic atomization device. In other examples, the atomizer or the cigarette cartridge can be used in combination with the power supply component (or the cigarette rod) first, and then connected to the liquid storage component 200 for use.

[0112] It should be noted that there may be multiple liquid storage components 200 .

[0113] It should be noted that in other examples, it is also feasible that the electronic atomization device cannot be used and inhaled before the housing component 201 is not connected to the housing component 101. That is, the electronic atomization device can be used and inhaled only after the housing component 201 is connected to the housing component 101, and the atomization component 104 can atomize both the first liquid matrix and the second liquid matrix.

[0114] It should be noted that no air flow channel is provided in the housing assembly 201. In other examples, part of the air flow channel may be provided in the housing assembly 201. When the housing assembly 201 is connected to the housing assembly 101, the air flow channel in the housing assembly 201 is connected to the air flow channel in the housing assembly 101, thereby forming a complete air flow channel to transmit the aerosol generated by the atomization assembly 104.

[0115] It should be noted that, in other examples, when the housing assembly 201 is connected to the housing assembly 101 , it is also feasible that the liquid storage cavity 202 is arranged around at least a portion of the liquid storage cavity 103 .

[0116] It should be noted that in other examples, it is also feasible to connect the through hole 109 and the through hole 201d2, or the through hole 110 and the through hole 201d3, respectively, through an independent connector. In this case, the internal channel of the connector may also constitute a partial liquid channel or a partial air channel.

[0117] It should be noted that, in other examples, a switch member may be provided on the liquid channel (air channel), and the switch member is configured to selectively open or close the liquid channel (air channel). The switch member includes a manually operated switch member to selectively open or close the liquid channel (air channel) under manual operation of the user. It is also feasible that the switch member includes an electrically operated switch member to selectively open or close the liquid channel (air channel) under electrical operation.

[0118] like Fig.13 As shown, in other examples, one end of the wall defining the through hole 201b5 extends into the liquid storage chamber 202, but is not arranged near the top of the liquid storage chamber 202, which is also feasible; when the liquid storage chamber 202 is injected with liquid matrix, the liquid matrix can flow into the through hole 201b5; when the housing assembly 201 is connected to the housing assembly 101, the liquid matrix in the through hole 201b5 can be discharged back to the liquid storage chamber 202, and the liquid matrix in the liquid storage chamber 202 can flow into the through hole 201d3, and then flow toward the through hole 110. When negative pressure is generated as the liquid matrix in the liquid storage chamber 103 decreases, the negative pressure can squeeze the liquid matrix in the through hole 201b5, the through hole 201d3 and the through hole 110 into the liquid storage chamber 202. At this time, the bubbles generated by the negative pressure can be discharged into the air part of the liquid storage chamber 202 through the liquid matrix in the liquid storage chamber 202, thereby balancing the air pressure difference between the liquid storage chamber 103 and the liquid storage chamber 202, so that the second liquid matrix stored in the liquid storage chamber 202 can flow smoothly to the liquid storage chamber 103 through the liquid channel, and the consumed liquid matrix is ​​replenished to the liquid storage chamber 103 in time.

[0119] Figure 14-Figure 19 This is an electronic atomization device 100 and a liquid storage component 200 provided in another embodiment of the present application. Figure 14-Figure 19 For the examples, the parts with the same mark and their descriptions can refer to Figure 1-Figure 12 Examples and their explanations. It should be noted that Figure 14-Figure 19 In the example, the wall defining the through hole 201b5 is Fig.13 The same as the example, it can be understood that it is also possible to use Figure 1-Figure 12 The structure of the example.

[0120] exist Figure 14-Figure 19 In the example, Figure 1-Figure 12 The difference between the examples is that the outer surface of the wall defining the through hole 109 also has a protrusion 109a, and the outer surface of the wall defining the through hole 110 also has a protrusion 110a; correspondingly, the inner surface of the sealing member 201d also has a slot 201d6 and a slot 201d7. When the housing assembly 201 is connected to the housing assembly 101, the protrusion 109a is clamped in the slot 201d6, and the protrusion 110a is clamped in the slot 201d7. In this way, when the housing assembly 201 is disassembled from the housing assembly 101, the sealing member 201d can be driven and move outward, thereby returning to the state when the housing assembly 201 is not connected to the housing assembly 101, that is, the position (second position) of closing the through hole 201b5 to prevent the liquid matrix from leaking out. Specifically, the through hole 201b4 is connected to the through hole 201d2; and the other end of the through hole 201b5 is staggered with one end of the through hole 201d3, so that the through hole 201b5 is not connected to the through hole 201d3. Fig.15 Such arrangement allows the liquid storage component 200 to be disassembled and reused repeatedly.

[0121] In other variations, the connection can be realized by only one protrusion and one corresponding slot. Alternatively, the sealing member 201d and the wall defining the through hole 109 or the through hole 110 can be connected by other connection methods.

[0122] In another variation, an elastic member, such as a compression spring, may be provided in the receiving cavity 201b3 of the bottom cover 201b. One end of the elastic member is fixed in the receiving cavity 201b3, and the other end is connected to the sealing member 201d, such as abutting or fixedly connected. In this way, when the housing assembly 201 is connected to the housing assembly 101, the elastic member may be in a compressed state; when the housing assembly 201 is disassembled from the housing assembly 101, the sealing member 201d may move outward under the elastic force of the elastic member, thereby returning to the state when the housing assembly 201 is not connected to the housing assembly 101.

[0123] In a further implementation, a blocking member 201e is further provided on the bottom cover 201b. When the sealing member 201d is driven to move outward, the blocking member 201e can prevent the sealing member 201d from falling off from the receiving cavity 201b3.

[0124] It should be noted that in Figure 14-Figure 19 In the example of the embodiment, the sealing member 201d moves between the first position and the second position, thereby opening the liquid channel or closing the liquid channel. In other examples, the sealing member 201d moves between the first position and the second position, thereby only opening the air channel or only closing the air channel, which is also feasible. It can be further understood that simultaneously opening the air channel and the liquid channel or simultaneously closing the air channel and the liquid channel is also feasible.

[0125] It should be noted that the preferred embodiments of the present application are given in the specification and drawings of the present application. However, 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 used as additional limitations on the content of the present application.

In addition, the above-mentioned technical features continue to be combined with each other to form various embodiments not listed above, which are all regarded as the scope of the description of the present application; further, for ordinary technicians in this field, they can be improved or transformed according to the above description, and all these improvements and transformations should belong to the scope of protection of the claims attached to the present application.
