Description

Technical Field

[0001] The embodiments of the present application relate to the field of electronic atomization technology, and in particular to an electronic atomization device and a liquid storage device for the electronic atomization device. Background Art

[0002] Smoking articles (eg, cigarettes, cigars, etc.) burn tobacco during use to produce tobacco smoke. People have attempted to replace these tobacco-burning articles by creating products that release compounds without combustion.

[0003] An example of such a product is a heating device that releases compounds by heating rather than burning a material. For example, the material may be tobacco or other non-tobacco products that may or may not contain nicotine. As another example, there are aerosol-providing products, such as so-called electronic atomization devices. These devices typically contain a liquid that is heated to vaporize it, thereby producing an inhalable aerosol. The liquid may contain nicotine and / or a fragrance and / or an aerosol-generating substance (e.g., glycerol). Known electronic atomization devices replenish a liquid matrix to a reusable body by an independently replaceable liquid source. Utility Model Content

[0058] 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 implementation methods.

[0059] The present application proposes an electronic atomization device for atomizing a liquid matrix to generate an aerosol.

[0060] Figures 1 to 3 A schematic diagram of an electronic atomization device according to an embodiment is shown; in this embodiment, the electronic atomization device includes a first body 100 and a second body 200; the first body 100 and the second body 200 can both exist independently and can be combined with each other.

[0061] In one embodiment, the first body 100 can store more liquid matrix than the second body 200, so as to replenish the liquid matrix to the second body 200 during use. The second body 200 can store relatively less liquid matrix and atomize the liquid matrix to produce an aerosol. Before the first body 100 and the second body 200 are combined, they exist independently of each other; and after the first body 100 is combined with the second body 200, they jointly define a complete electronic atomization device for use or aerosol inhalation by the user. Or in some embodiments, the first body 100 is mainly used as a liquid reservoir for storing more liquid matrix; the second body 200 defines the atomization function part for storing relatively less liquid matrix and atomizing to produce an aerosol.

[0062] In some embodiments, when the first body 100 and the second body 200 are separated or exist independently, they cannot be used or sucked by the user independently. Figures 1 to 4 As shown in the figure, the first body 100 at least partially defines a mouthpiece for a user to use or inhale; the second body 200 can atomize a liquid matrix to generate an aerosol. When the first body 100 is removed or separated from the second body 200, the first body 100 cannot atomize the liquid matrix to generate an aerosol alone, and the second body 200 cannot be inhaled by a user alone.

[0063] In some embodiments, the first body 100 and the second body 200 can only be used by the user when they are combined to define a complete electronic atomization device, and the liquid matrix inside them is completely recycled after being consumed. In some embodiments, after the first body 100 is combined with the second body 200 to define a complete electronic atomization device, the first body 100 cannot be disassembled or replaced from the second body 200.

[0064] Alternatively, in some other embodiments, the first body 100 is removably coupled to the second body 200; in use, the first body 100 is used as a consumable and can be replaced, while the second body 200 is reusable; when the liquid matrix in the first body 100 is consumed, the user can remove the consumed first body 100 from the second body 200 and replace it with a new first body 100.

[0065] according to Figures 1 to 7 As shown, the first body 100 has a proximal end 110 and a distal end 120 opposite to each other in the longitudinal direction; in use, the proximal end 110 is an end close to the user for suction; and the distal end 120 is an end away from the user.

[0066] according to Figures 1 to 7As shown, the first body 100 includes several components disposed within a first housing 10 (which may be referred to as a housing). The overall design of the first housing 10 may vary, and the type or configuration of the first housing 10 that may define the overall size and shape of the first body 100 may vary. Generally, the first housing 10 may be formed of a single integral housing, or the first housing 10 may be formed of two or more separable bodies. Figures 1 to 7 As shown, the first housing 10 may include one or more reusable components; the first housing 10 is close to and defines the proximal end 110 of the first body 100; in some examples, all or only part of the first housing 10 may be formed of a metal or alloy such as stainless steel, aluminum, or other suitable materials including various plastics (e.g., polycarbonate), metal-plating over plastic, ceramic, etc. The first housing 10 is open toward the distal end 120.

[0067] exist Figures 1 to 7 As shown in FIG. 1 , the first body 100 further includes a closing element 140 , which is close to and defines the distal end 120 of the first body 100 . Furthermore, the opening of the first housing 10 toward the distal end 120 is closed by the closing element 140 .

[0068] exist Figures 1 to 7 As shown in FIG. 1 , the first housing 10 includes:

[0069] The first part 11 and the second part 12 are arranged in sequence along the longitudinal direction; when the first body 100 is combined with the second body 200, the second part 12 is inserted or extended into the second body 200, and the first part 11 is located outside the second body 200. The first part 11 and the second part 12 have different widths or thicknesses, so that a step is formed or defined between the first part 11 and the second part 12; when the first body 100 is combined with the second body 200, the first end 210 of the second body 200 abuts against the step between the first part 11 and the second part 12 to provide a stop.

[0070] according to Figures 1 to 7 As shown, at least one or more connecting structures 121 are arranged on the outer surface of the second part 12. When the first body 100 is combined with the second body 200, the second part 12 is inserted or extended into the second body 200, and a mechanical connection is established with the second body 200 by at least one or more connecting structures 121, so that the first body 100 is stably combined with the second body 200. Figures 1 to 7 In the illustrated embodiment, the connection structure 121 is, for example, a protrusion or a groove located on the outer surface of the second portion 12 .

[0071] according to Figures 1 to 7 As shown, the first body 100 further includes:

[0072] An air outlet 113, located at the proximal end 110, for the user to draw air;

[0073] an aerosol output tube 111 extending from the air outlet 113 toward the distal end 120 for delivering the aerosol to the air outlet 113; in an embodiment, the aerosol output tube 111 is integrally molded with the first housing 10;

[0074] The first liquid storage chamber 112 is used to store a liquid matrix; at least a portion of the first liquid storage chamber 112 is defined between the aerosol output tube 111 and the first shell 10. The side of the first liquid storage chamber 112 close to the proximal end 110 is closed, and the boundary of the first liquid storage chamber 112 toward the distal end 120 is closed or defined by the closure element 140. In use, the liquid matrix in the first liquid storage chamber 112 leaves the closure element 140. In some embodiments, the first liquid storage chamber 112 is mainly defined between the first portion 11 of the first shell 10 and the aerosol output tube 111; and at least a portion of the first shell 10, such as the first portion 11, is transparent. Therefore, the liquid matrix in the first liquid storage chamber 112 is visible through the outer surface of the first portion 11 of the first shell 10.

[0075] according to Figures 1 to 7 As shown, the first body 100 also includes:

[0076] The sealing element 140 is substantially arranged perpendicular to the longitudinal direction of the first body 100 and is arranged at the distal end 120 of the first body 100. The sealing element 140 is close to and closes the opening of the first liquid storage chamber 112 toward the distal end 120.

[0077] according to Figures 1 to 7 As shown, a tracheal through hole 143 is also arranged on the sealing element 140 ; ​​after assembly, the aerosol output tube 111 at least partially passes through the tracheal through hole 143 and then extends to the outside of the first body 100 , thereby facilitating connection with the second body 200 .

[0078] In some embodiments, the closure element 140 is rigid, for example, made of a rigid polymer plastic. The closure element 140 is combined with the first housing 10 by a tight fit, and a seal is formed therebetween. In this embodiment, there is no flexible sealing material between the closure element 140 and the first housing 10 to provide a seal.

[0079] according to Figures 1 to 7As shown, at least one or more liquid output connectors 144 are arranged on the closure element 140; at least one or more liquid output connectors 144 are arranged to extend away from the liquid storage chamber 112. In this embodiment, at least one or more liquid output connectors 144 are arranged to extend toward the distal end 120. And at least one or more liquid output connectors 144 terminate at the distal end 120 and define the distal end 120. In an embodiment, the liquid output connector 144 is a hollow tubular shape. The liquid output connector 144 surrounds or defines a liquid output channel 141; the liquid output channel 141 is used to provide a channel path for the liquid matrix in the first liquid storage chamber 112 to leave or be output. After assembly, the liquid matrix in the first liquid storage chamber 112 can only be output or leave from the liquid output channel 141 in the liquid output connector 144 of the closure element 140.

[0080] according to Figures 1 to 7 As shown, the liquid output connector 144 is arranged to protrude relative to the first body 100 / closure element 140 at the distal end 120; or, the liquid output connector 144 is protruding relative to other parts of the first body 100 at the distal end 120. In this embodiment, the liquid output channel 141 basically extends along the longitudinal direction of the first body 100. In an embodiment, the liquid output connector 144 and / or the liquid output channel 141 has a length of about 4 to 12 mm. In an embodiment, the liquid output channel 141 has a diameter of 1.5 to 5.0 mm. For example, in a specific embodiment, the diameter of the liquid output channel 141 is 1.9 mm.

[0081] according to Figures 1 to 7 As shown, the liquid output connector 144 has a closed free end 146; and the distal end 120 of the first body 100 is defined by the closed free end 146 of the liquid output connector 144. The liquid output connector 144 has an increased outer diameter or tube wall thickness at the free end 146. In addition, abutment steps are defined on the outer surface of the liquid output connector 144 by the increased outer diameter or tube wall thickness. A liquid outlet 145 is arranged on the side wall of the liquid output connector 144 for the liquid matrix to flow out. In some embodiments, the diameter or width of the liquid outlet 145 can limit the liquid matrix from flowing out in large quantities and allow the liquid matrix to flow out only at a predetermined rate. In a specific embodiment, the diameter or width of the liquid outlet 145 is between 0.5 and 1.5 mm; in a more specific embodiment, the diameter or width of the liquid outlet 145 is 0.8 mm. The liquid outlet 145 is arranged near the free end 146 of the liquid output connector 144.

[0082] according to Figures 1 to 7 As shown, the first body 100 also includes:

[0083] The movably arranged shielding element 160 is arranged around the liquid output connector 144 ; the shielding element 160 can be moved relative to the liquid output connector 144 along the axial direction of the liquid output connector 144 to selectively shield and close the liquid outlet 145 or expose and open the liquid outlet 145 .

[0084] For example Figure 6 and Figure 7 Schematic diagrams showing the shielding element 160 in an open position and a closed position. Figure 6 In the embodiment, the shielding element 160 surrounds or wraps the liquid output connector 144 from the outside, and shields and closes the liquid outlet 145 to prevent the liquid matrix from being output from the liquid outlet 145. When the shielding element 160 moves along the axial direction of the liquid output connector 144 to Figure 7 In the open position, for example Figure 7 As indicated by the middle arrow P3 , the shielding element 160 avoids the liquid outlet 145 , thereby revealing and opening the liquid outlet 145 to allow the liquid medium to be output from the liquid outlet 145 .

[0085] In some embodiments, the shielding element 160 is flexible, for example, made of flexible silicone, thermoplastic elastomer, etc. In some embodiments, the shielding element 160 is configured to be annular around the liquid output connector 144 .

[0086] according to Figures 1 to 7 As shown, the first body 100 further includes:

[0087] The elastic element 150 is used to provide elastic force to bias the shielding element 160 toward the closed position and to stably maintain the shielding element 160 in the closed position.

[0088] In an embodiment, the elastic element 150 comprises a linear spring surrounding the liquid output connector 144. In assembly, the elastic element 150 is arranged between the closing element 140 and the shielding element 160. One end of the elastic element 150 abuts against or connects to the closing element 140, and the other end abuts against or connects to the shielding element 160. Figure 6 In the embodiment, the elastic force of the elastic element 150 stably presses the shielding element 160 against the step defined by the free end 146 to provide a stop, thereby stably maintaining the shielding element 160 in the closed position. The elastic element 150 can be actuated between an extended state and a compressed state, and is biased to return to the extended state; Figure 6 In the embodiment, when the shielding element 160 is in the closed position, the elastic element 150 is in the extended state; Figure 7 In the embodiment, the elastic element 150 is pressed into a compressed state.

[0100] After assembly, the first support portion 3210, the second support portion 3220 and the first end 210 of the second housing 20 define a receiving cavity 211. The second support portion 3220 is close to the second side 290; and the second support portion 3220 extends substantially straight, so that the boundary of the receiving cavity 211 close to the second side 290 is straight, which is beneficial for providing foolproofing or prompting the user to only receive the first body 100 in the receiving cavity 211 according to a predetermined direction.

[0125] The flexible base 370 is arranged between the third supporting portion 3230 and the second end 220 of the bracket 320; the flexible base 370 is at least partially inserted into the third supporting portion 3230, thereby closing the opening of the third supporting portion 3230 and / or the second liquid storage chamber 324 toward the second end 220, and supporting the liquid retaining element 330 and the atomization assembly.

[0126] Specifically, the base 370 is provided with a plug-in groove 372 for inserting and installing the tubular element 340; after assembly, the lower end of the tubular element 340 is inserted into the plug-in groove 372 of the base 370 for installation and fixation.

[0127] according to Figures 8 to 13 As shown, the second body 200 further includes:

[0128] An air inlet 221, located at the second end 220, for allowing external air to enter during suction;

[0129] The air inlet passage 371 , defined by the base 370 , provides a flow path for delivering air entering through the air inlet 221 to the atomizing assembly.

[0130] according to Fig.11 As shown, when the first body 100 is combined with the second body 200, the electronic atomization device defined includes:

[0131] The air flow channel provides a flow path from the air inlet 221 to the air outlet 113 via the atomizer assembly / heating element 360 to output the aerosol generated by the atomizer assembly / heating element 360 to the air outlet 113. In an embodiment, the complete air flow channel is partially defined by the second body 200 and partially defined by the first body 100. The supporting inner wall 321 surrounds and defines a portion of the air flow channel.

[0132] Specifically, the complete airflow path during suction is as follows Figure 8 and Fig.11 As shown by the middle arrow R2, the air entering from the air inlet 221 passes through the air inlet channel 371 to the atomizer assembly / heating element 360, and carries the aerosol generated by the heating element 360, passes through the support inner wall 321 and the trachea plug hole 311 of the sealing element 310 in turn, and then enters the aerosol output tube 111, and is finally output to the air outlet 113 to be inhaled by the user.

[0133] In some embodiments, the liquid retaining element 330 has an upper surface and a lower surface opposite to each other in the axial direction. The upper surface of the liquid retaining element 330 abuts against the supporting inner wall 321 and covers the liquid input interface 322. In some other specific embodiments, the base 370 is provided with a plurality of protrusions extending toward the liquid retaining element 330; after assembly, the lower surface of the liquid retaining element 330 abuts against the protrusions and forms or defines a gap with the base 370.

[0134] In some embodiments, the liquid retaining element 330 is defined by a single porous fiber element. Or in some other variations, the liquid retaining element 330 includes a first porous fiber material layer and a second porous fiber material layer arranged in sequence along the axial direction. The upper surface of the liquid retaining element 330 is defined by the first porous fiber material layer; and the lower surface of the liquid retaining element 330 is defined by the second porous fiber material layer. The liquid retaining element 330 is composed of the first porous fiber material layer and the second porous fiber material layer arranged in layers on top of each other.

[0135] In some embodiments, the second porous fiber material layer is made of a flexible capillary fiber material, such as natural cotton fiber, non-woven fabric fiber, and the like.

[0136] In some embodiments, the first porous fiber material layer includes artificial cotton, or hard artificial cotton or artificial foam made of filamentous polyurethane. For example, the first porous fiber material layer uses 138# hard synthetic organic polymer fiber; for another example, the first porous fiber material layer uses 138# hard synthetic organic polymer fiber with a density of 0.1-0.9 mg / mm 3 The first porous fiber material layer is made of oriented fibers that are basically arranged along the length direction, width direction or radial direction. The oriented fibers are arranged in the length direction or width direction of the first porous fiber material layer, so that the first porous fiber material layer has a strong bending resistance and thus has a hard characteristic. Specifically, for example, the first porous fiber material layer is hard artificial cotton including oriented polyester fibers, or hard artificial cotton or artificial foam made of filamentous polyurethane.

[0137] according to Figures 8 to 13 As shown, after assembly, the upper surface of the liquid retaining element 330 abuts against the port of the liquid input interface 322 defined by the support element 320, and covers the port of the liquid input interface 322, so as to prevent or avoid the air in the liquid input interface 322 from communicating with the outside air through the gap or clearance between the liquid retaining element 330 and the third support portion 3230. When the liquid matrix in the second liquid storage chamber 324 is consumed, the portion of the liquid retaining element 330 close to the upper surface is free of liquid matrix, and the porous pores in this portion provide a channel for transmitting negative pressure between the capillary channel / liquid input interface 322 and the second liquid storage chamber 324, so that the capillary channel / liquid input interface 322 can maintain balance with the negative pressure or pressure in the second liquid storage chamber 324.

[0138] according to Fig.11 and Fig.13 As shown, when the first body 100 is combined with the second body 200, the liquid output connector 144 of the closing element 140 of the first body 100 at least partially extends into or penetrates the liquid input interface 322, thereby connecting the first liquid storage chamber 112 of the first body 100 and the second liquid storage chamber 324 of the second body 200.

[0139] according to Fig.11 and Fig.13As shown, when the first body 100 is combined with the second body 200, the liquid outlet 145 on the liquid output connector 144 of the closing element 140 is located in the liquid input interface 322. Also, the outer surface of the liquid output connector 144 is not in contact with the inner surface of the liquid input interface 322, and a first distance d21 is defined between the outer surface of the liquid output connector 144 and the inner surface of the liquid input interface 322. Also, a second distance d22 is defined between the outer surface of the free end 146 of the liquid output connector 144 inserted into the liquid input interface 322 and the inner surface of the liquid input interface 322. Also, the free end 146 of the liquid output connector 144 inserted into the liquid input interface 322 is not in contact with the liquid retaining element 330 located in the second liquid storage chamber 324, and a third distance d23 is defined between the liquid output connector 144 and the liquid retaining element 330.

[0140] In an embodiment, the first spacing d21 is greater than the second spacing d22. In some optional embodiments, the first spacing d21 is approximately between 0.2 and 2.0 mm; in some optional embodiments, the second spacing d22 and / or the third spacing d23 are approximately between 0.1 and 0.5 mm. In some further specific embodiments, the first spacing d21 is approximately 0.5 mm; the second spacing d22 and / or the third spacing d23 are 0.15 mm. Or in some further specific embodiments, the first spacing d21 is approximately 1.0 mm; the second spacing d22 and / or the third spacing d23 are 0.25 mm.

[0141] In the embodiment, the capillary channel between the liquid output connector 144 and the liquid input interface 322 is defined by the first spacing d21 and the second spacing d22; the capillary channel defined by the first spacing d21 and the second spacing d22 adsorbs and retains the liquid matrix flowing out of the liquid outlet 145 of the liquid output connector 144, so as to prevent the liquid matrix in the first liquid storage chamber 112 from being replenished to the second liquid storage chamber 324 in large quantities. In the embodiment, the capillary channel defined by the first spacing d21 and the second spacing d22 can control the liquid matrix in the first liquid storage chamber 112 to be replenished to the second liquid storage chamber 324 according to a predetermined amount through capillary action; this is beneficial for preventing the second liquid storage chamber 324 from being oversaturated with the liquid matrix.

[0142] Specifically, in use, when the amount of liquid matrix absorbed and retained by the liquid retaining element 330 in the second liquid storage chamber 324 is sufficient, the negative pressure or pressure in the second liquid storage chamber 324 is lower than the preset threshold. Fig.13As shown by the middle arrow R11, the liquid matrix flowing out of the liquid outlet 145 of the liquid output connector 144 is absorbed and retained in the capillary channel defined by the first spacing d21 and the second spacing d22 and forms a liquid film to close the liquid outlet 145, thereby preventing the liquid matrix in the first liquid storage chamber 112 from being replenished in large quantities to the second liquid storage chamber 324. As the liquid matrix absorbed and retained by the liquid retaining element 330 in the second liquid storage chamber 324 is consumed, when the negative pressure in the second liquid storage chamber 324 exceeds a predetermined threshold, the liquid matrix retained in the capillary channel defined by the first spacing d21 and the second spacing d22, driven by the negative pressure, flows into and is replenished in the second liquid storage chamber 324 along the inner surface of the liquid input interface 322, as shown in FIG. Fig.13 As shown by the arrow R12. When a predetermined amount of liquid matrix is ​​added to the second liquid storage chamber 324 so that the negative pressure of the second liquid storage chamber 324 is lower than the predetermined threshold again, the liquid matrix flowing out of the liquid outlet 145 on the liquid output connector 144 is adsorbed in the capillary channel defined by the first spacing d21 and the second spacing d22 to reach a balance and prevent the liquid matrix from being further added to the second liquid storage chamber 324. Furthermore, by maintaining the capillary channel between the liquid output connector 144 and the liquid input interface 322, the first liquid storage chamber 112 can be controlled to only add liquid matrix to the second liquid storage chamber 324 according to a predetermined amount each time as the user sucks or uses. Specifically, the electronic atomization device can respond to the user's suction and automatically add the liquid matrix of the first body 100 to the second body 200 according to a predetermined amount during each suction process or during the lag period after the suction is completed.

[0143] In an embodiment, the volume of the first liquid storage chamber 112 in the first body 100 is greater than the volume of the second liquid storage chamber 324 in the second body 200. The amount of liquid matrix that can be absorbed and stored by the first liquid storage chamber 112 is greater than the amount of liquid matrix that can be absorbed and stored by the second liquid storage chamber 324 in the second body 200. For example, in some specific embodiments, the first liquid storage chamber 112 in the first body 100 can absorb and store 5 to 20 mL of liquid matrix, more specifically, for example, 10 mL; the second liquid storage chamber 324 in the second body 200 can store 5 to 20 mL of 0.5 to 3 mL of liquid matrix, more specifically, for example, 2 mL.

[0144] Or in some other variant embodiments, the capillary channel defined by the outer surface of the liquid output connector 144 and the inner surface of the liquid input interface 322 through non-contact can also be variably replaced by a capillary groove on the outer surface of the liquid output connector 144 and / or the inner surface of the liquid input interface 322. In this variant embodiment, when the liquid output connector 144 is inserted into the liquid input interface 322, the outer surface of the liquid output connector 144 can be against or in contact with the inner surface of the liquid input interface 322, and the capillary channel is defined between them by the capillary groove on the outer surface of the liquid output connector 144 and / or the inner surface of the liquid input interface 322.

[0145] Or in some other embodiments, a plurality of ridges extending in the longitudinal direction are arranged on the outer surface of the liquid output connector 144, and the plurality of ridges are arranged at intervals around the liquid output connector 144 in the circumferential direction. When the liquid output connector 144 is inserted into the liquid input interface 322, a capillary channel between the liquid output connector 144 and the liquid input interface 322 is defined by the gaps between the plurality of ridges.

[0146] exist Fig.11 and Fig.13 As shown, the third distance d23 defined between the liquid output connector 144 and the liquid retaining element 330 can prevent the liquid matrix in the capillary channel from being directly sucked away by the porous liquid retaining element 330 .

[0147] In an embodiment, the diameter of the liquid outlet 145 of the liquid output connector 144 is greater than the first spacing d21; and the first spacing d21 is greater than the second spacing d22. Through such an arrangement, the area of ​​the channel during the outflow of the liquid matrix is ​​gradually reduced, which is beneficial for gradually reducing the flow rate and improving the lock liquid to achieve a predetermined amount of liquid matrix supply.

[0148] according to Figures 3 to 13 As shown, the number of the liquid output connectors 144 of the first body 100 may include multiple ones; for example, in the embodiment, the number of the liquid output connectors 144 of the first body 100 is two. And, the number of the liquid outlets 145 on each liquid output connector 144 may also include multiple ones. Then, in use, when the liquid matrix in the first liquid storage chamber 112 flows out from at least one of the liquid outlets 145 on the multiple liquid output connectors 144, at least another liquid outlet 145 is used as an air inlet for providing air to enter the liquid output connector 144 and then to the first liquid storage chamber 112, so as to maintain the pressure balance in the first liquid storage chamber 112.

[0149] according to Figures 3 to 13As shown, the number of liquid output connectors 144 of the first body 100 is at least two, for example, the liquid output connector 144 may include a first connector and a second connector arranged in parallel; accordingly, the number of liquid input interfaces 322 on the second body 200 is also at least two, for example, the liquid input interface 322 may include a first interface and a second interface arranged in parallel. The first connector and the second connector are respectively arranged on both sides of the atomization assembly, and the first interface and the second interface are respectively arranged on both sides of the atomization assembly. In some embodiments, the free end 146 of the first connector and the free end 146 of the second connector are flush. And, the distance between the liquid outlet 145 on the first connector and the free end 146 is equal to the distance between the liquid outlet 145 on the second connector and the free end 146.

[0150] For example, in the embodiment, two liquid outlets 145 opposite to each other in the radial direction are arranged on the side wall of each liquid output connector 144; when the liquid matrix in the liquid output connector 144 flows out from one of the two liquid outlets 145 to the liquid input interface 322, the air in the liquid input interface 322 enters the liquid output connector 144 from the other of the two liquid outlets 145.

[0151] according to Figures 10 to 13 As shown, during the process of the user operating to combine the first body 100 with the second body 200, the bracket 320 drives the shielding element 160 of the first body 100 to move from the closed position to the open position, so that when the first body 100 is combined with the second body 200, the liquid outlet 145 of the liquid output connector 144 extends into the liquid input interface 322 and is exposed to form conduction.

[0152] Specifically, according to Figure 8 and Fig. 9 As shown, when the sealing element 310 is received in the accommodating cavity 323, the inner diameter of the avoidance hole 312 of the sealing element 310 is slightly larger than the inner diameter of the liquid input interface 322; thereby, an operation step 326 is formed between the accommodating cavity 323 of the bracket 320 and the liquid input interface 322; when the user operates to combine the first body 100 with the second body 200, the operation step 326 blocks the shielding element 160, so that the liquid output connector 144 is inserted into the liquid input interface 322 and moves relative to the shielding element 160, so that the shielding element 160 moves from the closed position to the open position to open the liquid outlet 145. In the embodiment, the operation step 326 is partially defined by the supporting inner wall 321 and partially defined by the bottom wall of the accommodating cavity 323.

[0153] During the user operation, the operation step 326 blocks the shielding element 160 to make it move relative to the liquid output connector 144. Figures 10 to 13As shown. Among them:

[0154] Fig.10 and Fig.11 The following figure shows the Fig.10 The arrow P11 in the middle shows a schematic diagram of a state in the process of combining the first body 100 with the second body 200; there is still a distance d11 between the first body 100 and the second body 200, so that the predetermined combination state is not reached. Fig.10 and Fig.11 As shown in FIG, the liquid output connector 144 is only partially inserted into or inserted into the liquid input interface 322, and the shielding element 160 in the closed position abuts against the operating step 326 to form a blockage. Fig.10 and Fig.11 In the state shown, only the free end 146 of the liquid output connector 144 extends into the liquid input interface 322. Fig.10 and Fig.11 As shown, the elastic element 150 is in an extended state.

[0155] Fig.12 and Fig.13 The user operation is shown in Fig.12 The arrow P12 further Fig.10 The first body 100 is pressed to be combined with the second body 200 in a predetermined combination state; Fig.12 and Fig.13 As shown in , the user further presses the first body 100, and the liquid output connector 144 further extends or inserts into the liquid input interface 322, while the shielding element 160 is blocked by the operating step 326 and stays in the sealing element 310. Fig.13 In the predetermined combined state shown, the liquid outlet 145 of the liquid output connector 144 extends into the liquid input interface 322 and is exposed, thereby forming conduction. Fig.12 and Fig.13 As shown, the elastic element 150 is in a compressed state.

[0156] exist Fig.12 and Fig.13 As shown, when the first body 100 is combined with the second body 200 in a predetermined combination state, the shielding element 160 is blocked and thus retained in the avoidance hole 312 of the sealing element 310; and, the annular shielding element 160 is at least partially radially compressed or squeezed by the sealing element 310 and the liquid output connector 144, thereby providing a seal therebetween.

[0157] In some embodiments, when the first body 100 is disassembled or removed from the second body 200 by a user, the elastic element 150 provides bias to move the shielding element 160 from an open position to a closed position; so that when the first body 100 is removed and taken out, the liquid outlet 145 is closed.

[0158] It should be noted that the preferred embodiments of the present application are given in the specification and drawings of the present application, but are not limited to the embodiments described in the specification. Furthermore, it is possible for a person of ordinary skill in the art to make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to the present application.
