[0023] To facilitate understanding of this application, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "upper," "lower," "left," "right," "inner," "outer," and similar expressions used in this specification are for illustrative purposes only.

[0024] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0025] like Figures 1-4 As shown, an embodiment of this application provides an electronic atomizing device including a device body 100 and a liquid storage component 200, wherein the number of liquid storage components 200 may be one or more.

[0026] The main body 100 of the device includes a first housing 101, which may be composed of multiple components, such as a main housing 101a and a bottom housing 101b disposed at the bottom of the main housing; in other examples, the first housing 101 may also be integrally formed.

[0027] A nozzle 102 is provided at the top of the first housing 101. The nozzle 102 is integrally formed with the first housing 101, but in other examples it can also be formed separately. The nozzle 102 is used for the user to inhale the aerosol generated by atomization.

[0028] A first reservoir 103 for storing a first liquid matrix is ​​formed within the first housing 101. Generally, the capacity of the first liquid matrix stored in the first reservoir 103 is between 0.1 ml and 2 ml, for example, 0.5 ml, 0.8 ml, 1 ml, 1.5 ml, etc. The first liquid matrix can be a liquid containing tobacco substances including volatile tobacco aroma components, or it can be a liquid containing non-tobacco substances. For example, the liquid matrix may include water, solvents, ethanol, plant extracts, flavorings, fragrances, or vitamin mixtures. Flavorings may include menthol, peppermint, spearmint oil, various fruit flavoring components, etc., but are not limited to these. Fragrances may include ingredients capable of providing the user with a variety of aromas or flavors. Vitamin mixtures may be substances containing at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but are not limited to these. Additionally, the first liquid matrix may include aerosol forming agents such as glycerin and propylene glycol.

[0029] The first liquid storage cavity 103 is also provided with a liquid storage medium 103a, for example made of fiber material or porous material. The first liquid storage cavity 103 can be filled with fiber cotton. The liquid storage medium 103a is used to absorb and hold the first liquid substrate and provide the first liquid substrate to the atomization core 104. When the liquid storage medium 103a is saturated after liquid injection, the content of the liquid substrate in the liquid storage medium 103a is between 0.1 ml and 2 ml, for example 0.5 ml, 0.8 ml, 1 ml, 1.5 ml or 2 ml, and the like. After the liquid storage medium 103a absorbs the first liquid substrate to near saturation, the first liquid storage cavity 103 can be divided into two parts by the end surface of the liquid storage medium 103a. The part of the first liquid storage cavity 103 not occupied by the liquid storage medium 103a is an air part, and the part occupied by the liquid storage medium 103a is a liquid substrate part.

[0030] The first housing 101 is provided with an atomization core 104 for atomizing the liquid substrate to generate aerosol.

[0031] In an example, the atomization core 104 includes a liquid transfer unit and a heating element.

[0032] The liquid transfer unit can transfer the liquid substrate in the first liquid storage cavity 103 to the heating element. For example, the liquid transfer unit can be cotton fiber, ceramic fiber, glass fiber, or porous ceramic, porous glass, and the like, but is not limited thereto. The liquid transfer unit can be configured in a tubular structure, a plate structure, or other regular or irregular shapes.

[0033] The heating element is used to heat the atomized liquid substrate to generate aerosol. The heating element can be a metal wire, a conductive track, a metal plate, a ceramic heater, and the like, but is not limited thereto. In addition, the heating element can be composed of a conductive heating wire such as a nichrome wire. The heating element can be made of a material with suitable electrical resistance temperature coefficient characteristics, for example: stainless steel 316, titanium, nickel, nickel-chromium alloy, and the like. The heating element can be arranged to be wound around the structure of the liquid transfer unit. The heating element can be heated by current supply and transfer heat to the liquid substrate in contact with the heating element to heat the liquid substrate, thereby generating aerosol.

[0034] It should be noted that the atomization core 104 is not limited to the above embodiments. In other examples, the heating element can also be a susceptor that can be heated by penetrating a variable magnetic field, or an infrared heater that radiates infrared rays. In another example, an ultrasonic atomizer can also be used instead.

[0035] The first housing 101 is also provided with an airflow passage 105 to transport the aerosol generated by the atomization core 104 to the mouthpiece 102, so as to be inhaled by the user.

[0036] In an example, the lower end of the airflow passage 105 is in communication with an air inlet, which can be provided on the bottom wall of the first housing 101; the upper end of the airflow passage 105 is connected with the suction nozzle 102, i.e. in communication with an air outlet (the dashed arrow S1 in the figure is the flow direction of the airflow in the airflow passage 105). The first liquid storage cavity 103 is arranged around at least part of the airflow passage 105. The atomizing core 104 is arranged at least partially in the airflow passage 105, or the atomizing core 104 is configured in a tubular structure, the hollow part inside which defines part of the airflow passage 105. The wall forming the airflow passage 105 is provided with a liquid passing hole to communicate the first liquid storage cavity 103 and the atomizing core 104, so that the liquid matrix in the first liquid storage cavity 103 can be transferred to the atomizing core 104 and atomized.

[0037] The first housing 101 is further provided with a circuit board 106, which integrates various components. The circuit board 106 can control the overall operation of the device body 100. In detail, the circuit board 106 not only controls the operation of the battery 107 and the atomizing core 104, but also controls the operation of other components in the device body 100. In addition, the circuit board 106 can determine whether the device body 100 can operate by checking the state of the components of the device body 100.

[0038] The circuit board 106 includes at least one control unit. The control unit can include a logic gate array, or can include a combination of a general-purpose microcontroller and a memory storing a program executable by the microcontroller. In addition, those skilled in the art will understand that the circuit board 106 can include another type of hardware.

[0039] The battery 107 provides power for operating the device body 100. For example, the battery 107 can provide power to heat the heating element, and can provide power required for operating the circuit board 106. In addition, the battery 107 can provide power required for operating other components provided in the device body 100.

[0040] The battery 107 can be, but is not limited to, a lithium iron phosphate (LiFePO4) battery. For example, the battery 107 can be a lithium cobaltate (LiCoO2) battery or a lithium titanate battery. The battery 107 can be a rechargeable battery or a disposable battery.

[0041] It should be noted that only components related to the present embodiment are shown in the figure. Those skilled in the art will understand that the device body 100 can further include components other than those shown in the figure. Figures 1-4Other general components other than the components shown. For example, the first housing 101 can also be provided with a puff detector 108 for detecting a user's puffing action and generating a corresponding electrical signal, i.e., detecting whether the device body 100 is puffed, so that the circuit board 106, e.g., a control unit, controls the operation of the battery 107, the heating element, etc. according to the electrical signal, e.g., controls the battery 107 to provide power to the heating element, so that the heating element heats the aerosol liquid substrate. The puff detector 108 can employ a common pressure sensor, differential pressure sensor, airflow sensor, etc.

[0042] It is also necessary to note that, in Figures 1-4 In the example, the above components are integrally formed, and the device body 100 is a general connected device. In other examples, the device body 100 can also include an atomizer, and a power assembly detachably connected with the atomizer, the atomizer is also commonly referred to as a cartridge, and the power assembly is also commonly referred to as a stick; wherein the components such as the circuit board 106, the battery 107, and the puff detector 108 are in the power assembly; the components such as the mouthpiece 102, the first liquid storage cavity 103, and the atomizing core 104 are in the atomizer.

[0043] The liquid storage component 200 includes a second housing 201, which can be composed of multiple components, such as a main shell 201a, a bottom shell 201b, and a sealing member 201c. The main shell 201a is connected with the bottom shell 201b; in preferred implementations, the main shell 201a and the bottom shell 201b are detachably connected, e.g., snap-fit connected. Part of the bottom shell 201b extends into the main shell 201a, and the sealing member 201c is arranged between the bottom shell 201b and the main shell 201a to seal the gap therebetween. In preferred implementations, the sealing member 201c is annular and is sleeved on the bottom shell 201b. In other examples, the second housing 201 can also be integrally formed

[0044] The second housing 201 is formed with a second liquid storage cavity 202 for storing a second liquid substrate.

[0045] Similar to the first liquid substrate, the second liquid substrate can be a liquid including a tobacco-containing substance containing volatile tobacco flavor components, and can also be a liquid including a non-tobacco substance. For example, the liquid substrate can include water, a solvent, ethanol, a plant extract, a flavor, a flavoring agent, or a vitamin mixture. The flavor can include menthol, peppermint, spearmint oil, various fruit flavor components, etc., but is not limited thereto. The flavoring agent can include components capable of providing a user with a variety of flavors or flavors. The vitamin mixture can be a substance mixed with at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but is not limited thereto. In addition, the second liquid substrate can include an aerosol forming agent such as glycerol and propylene glycol.

[0046] It is to be noted that the second liquid base can be different from the first liquid base in composition or property, or can be the same. For example, in some examples, the second liquid base is different from the first liquid base in composition, or the second liquid base is different from the first liquid base in concentration. For example, in other examples, the second liquid base is the same as the first liquid base in composition, the second liquid base can be part of a liquid formulation, and the first liquid base can be another part of the liquid formulation. The second liquid base can be introduced into the first liquid chamber 103 as a supplement to the first liquid base, so as to increase the number of puffs of the electronic atomization device.

[0047] The volume of the second liquid chamber 202 is greater than the volume of the first liquid chamber 103. Generally, the capacity of the second liquid base stored in the second liquid chamber 202 is between 2ml and 10ml, for example, 4ml, 5ml, 6ml, 8ml, etc. It can be understood that the volume of the second liquid chamber 202 is slightly greater than the capacity of the second liquid base stored therein. In this way, after the second liquid chamber 202 stores the second liquid base, it can be divided into two parts, one part being an air part and the other part being a liquid base part.

[0048] The liquid storage component 200 is independent of the device body 100, for example, in a packaged state or an unused state, the liquid storage component 200 is separated from the device body 100, and the user can assemble the liquid storage component 200 on the device body 100 before use.

[0049] In an example, the liquid storage component 200 is detachably connected to the device body 100.

[0050] Specifically, the first shell 101 of the device body 100 is substantially cuboid, and the upper left part of the first shell 101 has a mounting space B, which is in the form of a notch, i.e., the front side, the back side, the left side and the top of the mounting space B are all open. The second shell 201 can be assembled to the mounting space B in the direction from the left side of the first shell 101 to the right side of the first shell 101. After the second shell 201 is assembled to the first shell 101, the first shell 101 and the second shell 201 jointly define the outer shell of the electronic atomization device. In a specific implementation, the device body 100 and the liquid storage component 200 can be detachably connected by using a buckle mechanism. For example, the first shell 101 of the device body 100 is provided with a clamping hole 101a1, and the second shell 201 of the liquid storage component 200 is provided with a clamping buckle 201a1, and the clamping buckle 201a1 and the clamping hole 101a1 are buckled to realize the detachable connection of the device body 100 and the liquid storage component 200. In the example shown in the figure, the clamping buckle 201a1 is arranged on the side wall of the second shell 201 and close to the top of the second shell 201, and the clamping hole 101a1 is arranged on the first shell 101 and located on the right side of the mounting space B. The clamping buckle 201a1 includes a first cantilever 201a11 and a second cantilever 201a13 extending outward from the side wall of the second shell 201 in the width direction of the second shell 201, and the first cantilever 201a11 and the second cantilever 201a13 are arranged at intervals in the length direction of the second shell 201, the free end of the first cantilever 201a11 has a first protrusion 201a12 protruding toward the top of the second shell 201, and the free end of the second cantilever 201a13 has a second protrusion 201a14 protruding toward the bottom of the second shell 201. In this way, when the clamping buckle 201a1 is connected with the clamping hole 101a1, the free end of the first cantilever 201a11 and the free end of the second cantilever 201a13 can extend into the clamping hole 101a1, and the first protrusion 201a12 and the second protrusion 201a14 can be limited by the edge of the clamping hole 101a1 to prevent the clamping buckle 201a1 from being buckled off from the clamping hole 101a1, which can avoid the first shell 101 and the second shell 201 from being separated in the direction opposite to the assembly direction, i.e., in the direction from the right side of the first shell 101 to the left side of the first shell 101, and on the other hand, since the directions in which the first protrusion 201a12 and the second protrusion 201a14 protrude in the length direction of the second shell 201 are opposite, when the first shell 101 or the second shell 201 moves upward or downward, the first protrusion 201a12 and the second protrusion 201a14 will not be buckled off at the same time, which ensures the reliability of the connection between the first shell 101 and the second shell 201.

[0051] It can be understood that the above-mentioned clamping buckle is realized by a cantilever and a protrusion, which is also feasible. It can also be understood that the above-mentioned clamping hole is arranged on the second shell 201, and the above-mentioned clamping buckle is arranged on the first shell 101, which is also feasible.

[0052] In an example, a guide mechanism can be arranged between the device body 100 and the liquid storage component 200, so as to facilitate the assembly of the second shell 201 to the first shell 101 in the direction from the left side of the first shell 101 to the right side of the first shell 101. For example, a sliding block 101a2 is arranged on the first shell 101 of the device body 100, and a sliding groove 201b1 is arranged on the second shell 201 of the liquid storage component 200, and the sliding block 101a2 can slide in the sliding groove 201b1, so as to assemble the second shell 201 to the first shell 101. In the example in the figure, the sliding groove 201b1 is arranged at the bottom of the second shell 201, and the sliding block 101a2 is arranged on the first shell 101 and located at the bottom of the mounting space B. The sliding groove 201b1 includes a first baffle 201b12 and a second baffle 201b13 arranged at intervals along the length direction of the second shell 201 and a groove top 201b11, and the first baffle 201b12 and the second baffle 201b13 are arranged at intervals along the thickness direction of the second shell 201; the sliding block 101a2 includes a protrusion 101a21 extending along the length direction of the first shell 101 towards the mouthpiece 102 or the top of the first shell 101, and a sliding plate 101a22 connected with the protrusion 101a21 and extending horizontally along the width direction and the thickness direction of the first shell 101. In this way, when the second shell 201 is assembled to the first shell 101, the protrusion 101a21 moves in the gap 201b14 between the first baffle 201b12 and the second baffle 201b13, and the sliding plate 101a22 is limited by the first baffle 201b12 and the second baffle 201b13 and moves between the groove top 201b11 and the two baffles.

[0053] It can be understood that the above-mentioned sliding block is arranged on the second shell 201, and the above-mentioned sliding groove is arranged on the first shell 101, which is also feasible.

[0054] In further implementations, to prevent the device body 100 and the liquid storage component 200 from loosening or even falling off, the reliability of the connection between the device body 100 and the liquid storage component 200 is ensured. A retreat prevention mechanism can also be provided between the device body 100 and the liquid storage component 200. For example, the first housing 101 of the device body 100 is provided with a retreat prevention buckle 101a3, and the second housing 201 of the liquid storage component 200 is provided with a retreat prevention groove 201b2, the retreat prevention buckle 101a3 is buckled in the retreat prevention groove 201b2, thereby firmly connecting the second housing 201 to the first housing 101, and avoiding the second housing 201 from being separated from the first housing 101 in the direction opposite to the assembly direction (i.e., the direction from the right side of the first housing 101 to the left side of the first housing 101). In the example shown in the figure, the retreat prevention buckle 101a3 is arranged on the first housing 101 and located at the bottom of the installation space B, the retreat prevention buckle 101a3 and the sliding block 101a2 are arranged in sequence in the assembly direction, the retreat prevention buckle 101a3 is connected to one end of the sliding block 101a2, for example, connected to the end of the sliding block 101a22 close to the left side of the first housing 101; the retreat prevention groove 201b2 is arranged at the bottom of the second housing 201, the retreat prevention groove 201b2 and the sliding groove 201b1 are arranged in sequence in the assembly direction, and the retreat prevention groove 201b2 is located at one side of the sliding groove 201b1, i.e., corresponding to the side of the sliding groove 201b1 close to the left side of the second housing 201. In this way, when the second housing 201 is assembled to the first housing 101, the retreat prevention buckle 101a3 can be buckled in the retreat prevention groove 201b2 when the sliding block 101a2 is slid to the right position in the sliding groove 201b1, thereby firmly connecting the second housing 201 to the first housing 101.

[0055] It can be understood that the retreat prevention buckle is arranged on the second housing 201, and the retreat prevention groove is arranged on the first housing 101, which is also feasible.

[0056] It should be noted that the buckle mechanism, the guide mechanism, and the retreat prevention mechanism can be used in combination to reliably connect the second housing 201 to the first housing 101.

[0057] In an example, when the second housing 201 is connected to the first housing 101, the first liquid storage cavity 103 and the second liquid storage cavity 202 are arranged in sequence along the width direction of the electronic atomization device. The first liquid storage cavity 103 is arranged close to the right end of the electronic atomization device, and the second liquid storage cavity 202 is arranged close to the left end of the electronic atomization device.

[0058] In an example, when the second housing 201 is connected to the first housing 101, a connection channel A connecting the first liquid storage cavity 103 and the second liquid storage cavity 202 can be established between the first liquid storage cavity 103 and the second liquid storage cavity 202.

[0059] Specifically, the first shell 101 is further provided with a connector 101a4, and the second shell 201 is further provided with a plug-in interface 201b3. One end of the connector 101a4 is connected with the first shell 101, and the other end of the connector 101a4 extends away from the first shell 101 along the width direction of the first shell 101; the connector 101a4 has a through hole, one end of the through hole is in communication with the first liquid storage cavity 103, and the other end of the through hole is in communication with the outside of the first shell 101; one end of the plug-in interface 201b3 is arranged close to the bottom of the second liquid storage cavity 202 and is in communication with the second liquid storage cavity 202, and the other end of the plug-in interface 201b3 is in communication with the outside of the second shell 201. In this way, when the second shell 201 is connected with the first shell 101, the connector 101a4 can be plugged into the plug-in interface 201b3, so as to establish a connecting channel A between the second liquid storage cavity 202 and the first liquid storage cavity 103, and the connecting channel A is in communication with the second liquid storage cavity 202 and the first liquid storage cavity 103. The through hole in the connector 101a4 defines at least part of the connecting channel A.

[0060] It can be understood that the connector 101a4 and the plug-in interface 201b3 between the first shell 101 and the second shell 201 can also limit the movement of the first shell 101 or the second shell 201 along the length direction of the electronic atomization device, so as to cause the disconnection between the first shell 101 and the second shell 201.

[0061] In an example, a liquid guide medium is arranged in the connecting channel A to transfer the liquid substrate stored in the second liquid storage cavity 202 to the first liquid storage cavity 103. The gap between the liquid guide medium and the inner wall of the connecting channel A defines an air channel for air flow between the first liquid storage cavity 103 and the second liquid storage cavity 202. In this way, through the liquid guide medium, the second liquid substrate stored in the second liquid storage cavity 202 can supplement the consumed liquid substrate in the first liquid storage cavity 103; through the air channel, the air pressure difference between the first liquid storage cavity 103 and the second liquid storage cavity 202 can be balanced, so that the second liquid substrate stored in the second liquid storage cavity 202 can flow smoothly to the first liquid storage cavity 103, and the consumed liquid substrate in the first liquid storage cavity 103 can be supplemented in time, so as to avoid the negative pressure caused by the reduction of the liquid substrate in the second liquid storage cavity 202 to prevent the remaining liquid substrate from flowing into the first liquid storage cavity 103. It can be understood that the part of the connecting channel A occupied by the liquid guide medium can be considered as a liquid channel between the first liquid storage cavity 103 and the second liquid storage cavity 202.

[0062] In an example, the liquid guiding medium comprises a first liquid guiding medium 109 disposed in the joint 101a4, one end of the first liquid guiding medium 109 is disposed close to the liquid storage medium 103a and abuts or contacts the liquid storage medium 103a, and the other end of the first liquid guiding medium 109 is disposed close to the other end of the joint 101a4; the first liquid guiding medium 109 has a gap A1 with the inner wall of the joint 101a4, and the gap A1 defines at least part of the air passage.

[0063] The second liquid substrate stored in the second liquid storage cavity 202 can flow into the connecting passage A, and then be absorbed and transmitted by the first liquid guiding medium 109 to the liquid storage medium 103a, so as to replenish the consumed liquid substrate in the first liquid storage cavity 103 (as shown by the dashed arrow S2 in Figure 5 When the liquid substrate in the second liquid storage cavity 202 is reduced, the air in the first liquid storage cavity 103, for example, the air in the part of the space in the first liquid storage cavity 103 not occupied by the liquid storage medium 103a, flows into the connecting passage A along the gap between the liquid storage medium 103a and the cavity wall of the first liquid storage cavity 103, and then flows into the second liquid storage cavity 202 through the gap A1 between the first liquid guiding medium 109 and the inner wall of the joint 101a4 (as shown by the dashed arrow S3 in Figure 5 ), so as to balance the air pressure difference between the first liquid storage cavity 103 and the second liquid storage cavity 202, so that the second liquid substrate stored in the second liquid storage cavity 202 can flow smoothly to the first liquid storage cavity 103 and timely replenish the consumed liquid substrate in the first liquid storage cavity 103; Similarly, the air in the second liquid storage cavity 202 can also flow into the first liquid storage cavity 103 in the reverse direction through the above-mentioned path (as shown by the dashed arrow S3 in Figure 5 ), so as to balance the air pressure difference between the first liquid storage cavity 103 and the second liquid storage cavity 202.

[0064] The first liquid guiding medium 109 is prepared from flexible fibers such as cotton fibers, non-woven fabrics or sponge bodies, etc. In use, when the second liquid substrate stored in the second liquid storage cavity 202 flows to the first liquid storage cavity 103 through the connecting passage A, the first liquid guiding medium 109 can store and absorb the liquid substrate by capillary adsorption, so as to adjust the flow rate of the liquid substrate flowing from the second liquid storage cavity 202 to the first liquid storage cavity 103, both to prevent the liquid substrate from flowing too fast to cause leakage, and to release the liquid substrate to ensure the supply rate when the liquid substrate flows slowly.

[0065] In an example, the cross-sectional shape of the first liquid guide medium 109 matches the cross-sectional shape of the through-hole in the connector 101a4, for example, the cross-sectional shape of the through-hole in the connector 101a4 is oval or the cross-sectional shape of the connector 101a4 is track-shaped, while the cross-sectional shape of the first liquid guide medium 109 is also oval, but the outer surface of the first liquid guide medium 109 is further provided with a groove 109a, which, when the first liquid guide medium 109 is placed in the connection channel A, together with the inner wall of the connector 101a4 defines the boundary of the above-mentioned gap A1, that is, the boundary of the above-mentioned air channel. It can be understood that it is also feasible that the outer surface of the first liquid guide medium 109 is not provided with a groove 109a, and the inner wall of the connector 101a4 is provided with a groove.

[0066] In an example, the cross-sectional shape of the first liquid guide medium 109 can not match the cross-sectional shape of the through-hole in the connector 101a4, so that the above-mentioned gap A1 is defined by the shape difference between the two. For example, the cross-sectional shape of the through-hole in the connector 101a4 is oval or the cross-sectional shape of the connector 101a4 is track-shaped, while the cross-sectional shape of the first liquid guide medium 109 is square or circular. Thus, when the first liquid guide medium 109 is placed in the connection channel A, part of the outer surface of the first liquid guide medium 109 is in contact with the inner wall of the connector 101a4, while another part of the outer surface of the first liquid guide medium 109 is kept apart from the inner wall of the connector 101a4, thereby forming the above-mentioned gap A1.

[0067] In an example, a sealing ring 101a5 is sleeved on the connector 101a4. When the connector 101a4 is inserted into the insertion port 201b3, the sealing ring 101a5 can seal the gap between the connector 101a4 and the insertion port 201b3, preventing leakage of the liquid matrix.

[0068] In an example, when the second housing 201 is not connected to the first housing 101, the through-hole of the connector 101a4 can be plugged by a sealing member, for example, a removable silica gel plug or a silica gel cap, or a puncturable film member, to prevent leakage of the liquid matrix.

[0069] In an example, the insertion port 201b3 is provided with a movable member 203. The movable member 203 is configured to be movable relative to the second housing 201 between a first position and a second position. When moved to the first position (as shown in Figure 4 , the movable member 203 can prevent the liquid matrix in the second liquid storage cavity 202 from leaving or flowing out, for example, preventing the liquid matrix in the second liquid storage cavity 202 from flowing into the connection channel A; when moved to the second position (as shown in Figure 3 , the movable member 203 allows the liquid matrix in the second liquid storage cavity 202 to leave or flow out, for example, allowing the liquid matrix in the second liquid storage cavity 202 to flow into the connection channel A.

[0070] In an example, the movable member 203 is at least partially located in the insertion interface 201b3 when the movable member 203 is in the first position. When the second housing 201 is assembled to the first housing 101, the movable member 203 can be actuated by the connector 101a4 inserted into the insertion interface 201b3, and the movable member 203 is moved from the first position to the second position, for example, the movable member 203 is moved along the width direction of the second housing 201 from the first position to the second position. When the movable member 203 is moved to the second position, part of the movable member 203 is located in the second liquid storage cavity 202, and another part of the movable member 203 remains in the insertion interface 201b3.

[0071] In a further implementation, the second liquid storage cavity 202 further comprises a limiting portion 201b4, and the limiting portion 201b4 limits the movable member 203 when the movable member 203 is moved to the second position, thereby achieving the effect of assembly in place.

[0072] In an example, the movable member 203 comprises a sealing valve 203a. The sealing valve 203a is configured as a hollow cylindrical structure. The sealing valve 203a is arranged in the insertion interface 201b3 along the width direction of the second housing 201. One end of the sealing valve 203a close to the connector 101a4 is an open end, and the other end of the sealing valve 203a away from the connector 101a4 is a closed end. The sealing valve 203a has a through hole 203a1 on the side wall, and the through hole 203a1 is in communication with the internal hollow of the sealing valve 203a.

[0073] When the movable member 203 is moved to the first position, the through hole 203a1 of the sealing valve 203a is hidden in the insertion interface 201b3 and is blocked by the inner wall of the insertion interface 201b3, thereby preventing the liquid matrix in the second liquid storage cavity 202 from flowing into the sealing valve 203a through the through hole 203a1.

[0074] When the movable member 203 is moved to the second position, the through hole 203a1 of the sealing valve 203a is exposed in the second liquid storage cavity 202, thereby allowing the liquid matrix in the second liquid storage cavity 202 to flow into the sealing valve 203a through the through hole 203a1, and then flow out of the open end of the sealing valve 203a.

[0075] When the second housing 201 is combined with the first housing 101, the connector 101a4 inserted into the insertion interface 201b3 is in contact with the sealing valve 203a, and the open end of the sealing valve 203a is in contact with the connector 101a4, thereby allowing the connector 101a4 inserted into the insertion interface 201b3 to actuate the sealing valve 203a, and allowing the sealing valve 203a to move from the first position to the second position; on the other hand, the hollow part inside the sealing valve 203a is in communication with the through hole in the connector 101a4.

[0076] Thus, the second liquid substrate stored in the second reservoir 202 can flow into the sealing valve 203a through the through-hole 203al, and then flow into the joint 101a4 from the open end of the sealing valve 203a, so as to be absorbed by the first liquid guiding medium 109 and transferred to the liquid storage medium 103a, thereby replenishing the consumed liquid substrate in the first reservoir 103 (as shown by the dashed arrow S2 in FIG. 2B). Figure 5 When the liquid substrate in the second reservoir 202 is reduced, the air in the first reservoir 103, for example, the air in the part of the space in the first reservoir 103 not occupied by the liquid storage medium 103a, flows into the connecting channel A along the gap between the liquid storage medium 103a and the wall of the first reservoir 103, and then flows into the sealing valve 203a through the gap Al between the first liquid guiding medium 109 and the inner wall of the joint 101a4, and finally flows out of the sealing valve 203a through the through-hole 203al to the second reservoir 202 (as shown by the dashed arrow S3 in FIG. 2B), thereby balancing the air pressure difference between the first reservoir 103 and the second reservoir 202. Figure 5

[0077] In an example, the joint 101a4 has a dimension along the height direction of the first housing 101 greater than the dimension of the sealing valve 203a along the height direction of the second housing 201. Thus, when the joint 101a4 inserted into the insertion port 201b3 is in abutment with the sealing valve 203a, part of the first liquid guiding medium 109 can abut the open end of the sealing valve 203a, thereby preventing the first liquid guiding medium 109 from sliding into the sealing valve 203a.

[0078] In an example, the liquid guiding medium further comprises a second liquid guiding medium 203b arranged in the sealing valve 203a. The second liquid guiding medium 203b is arranged in the sealing valve 203a along the width direction of the second housing 201. The second liquid guiding medium 203b is made of or comprises flexible fibers such as cotton fibers, non-woven fabric, or sponge, etc. Similar to the first liquid guiding medium 109, the second liquid guiding medium 203b has a gap A2 with the inner wall of the sealing valve 203a, for example, defined by a groove 203bl on the outer surface of the second liquid guiding medium 203b.

[0079] Thus, when the joint 101a4 inserted into the insertion port 201b3 is in abutment with the sealing valve 203a, the second liquid guiding medium 203b can maintain contact with the first liquid guiding medium 109. When the second liquid substrate stored in the second reservoir 202 flows into the sealing valve 203a through the through-hole 203al, it can be absorbed by the second liquid guiding medium 203b and then transferred out of the second housing 201, and then transferred to the liquid storage medium 103a through the first liquid guiding medium 109, thereby replenishing the consumed liquid substrate in the first reservoir 103 (as shown by the dashed arrow S2 in FIG. 2B). Figure 5 ​air in the first liquid storage chamber 103 flows out to the second liquid storage chamber 202 (as indicated by the dotted arrow S3 in FIG. 3B) through the air passage, thereby balancing the air pressure difference between the first liquid storage chamber 103 and the second liquid storage chamber 202. Figure 5

[0080] It is to be noted that, in this example, the gap A1 between the first liquid guiding medium 109 and the inner wall of the connector 101a4 defines a part of the air passage (a first air passage), and the gap A2 between the second liquid guiding medium 203b and the inner wall of the sealing valve 203a defines another part of the air passage (a second air passage).

[0081] Similar to the first liquid guiding medium 109, the second liquid guiding medium 203b can store liquid matrix by capillary adsorption, so as to adjust the flow rate of the liquid matrix flowing from the second liquid storage chamber 202 to the first liquid storage chamber 103, preventing the liquid matrix from flowing too fast to cause leakage, and releasing the liquid matrix to ensure the supply rate when the liquid matrix flows too slowly. On the other hand, the second liquid guiding medium 203b abuts against the first liquid guiding medium 109, so as to prevent the first liquid guiding medium 109 from sliding towards the sealing valve 203a, and facilitate the transfer of the liquid matrix to the liquid storage medium 103a.

[0082] In an example, the movable member 203 further comprises a first sealing ring 203c and a second sealing ring 203d sleeved on the sealing valve 203a, the first sealing ring 203c, the through hole 203a1 and the second sealing ring 203d are arranged in sequence along the width direction of the second housing 201, i.e., the through hole 203a1 is sandwiched between the first sealing ring 203c and the second sealing ring 203d. In this way, when the movable member 203 is in the first position, the first sealing ring 203c and the second sealing ring 203d are both located between the outer surface of the sealing valve 203a and the inner wall of the plug-in port 201b3, and the first sealing ring 203c and the second sealing ring 203d can seal the gap between the outer surface of the sealing valve 203a and the inner wall of the plug-in port 201b3, preventing the leakage of the liquid matrix. When the movable member 203 is moved to the second position, the first sealing ring 203c is exposed in the second liquid storage chamber 202, and the second sealing ring 203d is still located between the outer surface of the sealing valve 203a and the inner wall of the plug-in port 201b3, and the second sealing ring 203d can still seal the gap between the outer surface of the sealing valve 203a and the inner wall of the plug-in port 201b3, preventing the leakage of the liquid matrix.

[0083] It is to be noted that, the connector can be arranged on the second housing 201, and the plug-in port can be arranged on the first housing 101, which is also feasible.​
