Description

Technical Field

[0001] This application relates to the field of atomization technology, specifically to a liquid supply mechanism and atomization device. Background Technology

[0002] In atomizing devices, the liquid supply mechanism typically supplies liquid passively to the atomizing element. During the liquid supply process, the pressure in the reservoir gradually decreases, which slows down the supply rate and results in a longer time required for the liquid matrix to wet the atomizing coil. If the user does not wait this long enough during actual use, there is a risk of the coil clogging. Utility Model Content

[0003] This application provides a liquid supply mechanism and an atomizing device to solve the problem of slow liquid supply speed in the liquid supply mechanism.

The housing also has a retaining member. The piston is movably connected to the housing, and the piston can cooperate with the retaining member and be locked to the retaining member. The driving member is connected to the piston. The locking between the piston and the retaining member can be released, and after release, the driving member can drive at least a portion of the piston to move toward the first liquid storage chamber to compress the volume of the first liquid storage chamber, thereby promoting the liquid matrix to flow out through the liquid outlet.

[0005] In some embodiments, the piston and the housing together define the first liquid reservoir.

[0006] In some embodiments, the piston has a first position in which it is locked to the retainer, and a second position in which it is disengaged from the retainer; the volume of the first reservoir partially defined when the piston is in the first position is greater than the volume of the first reservoir partially defined when the piston is in the second position.

[0009] In some embodiments, the piston is further provided with a mating portion spaced apart from the snap-fit ​​portion, and the mating portion can be driven to disengage the snap-fit ​​portion from the snap-fit ​​portion.

[0010] In some embodiments, the housing is provided with a guide member communicating with the first liquid storage chamber, the piston is at least partially disposed in the guide member, and the piston is slidable in the guide member toward the first liquid storage chamber.

[0011] In some embodiments, the housing has a third end and a fourth end opposite to each other, one end of the guide is held on the third end of the housing, and the other end of the guide extends into the first liquid storage cavity and is disposed near the fourth end of the housing.

[0012] In some embodiments, a first seal is further included between the outer wall of the piston and the inner wall of the guide.

[0013] In some embodiments, the drive member includes an elastic member, one end of which abuts against the piston and the other end of which abuts against the housing.

[0014] In some embodiments, the piston is provided with a receiving groove extending in the moving direction, and at least a portion of the elastic element is disposed within the receiving groove.

[0015] On the other hand, this application provides an atomizing device, which includes an atomizing mechanism and a liquid supply mechanism as described in any of the above embodiments, wherein the atomizing mechanism includes a second liquid storage chamber;

[0016] When the atomizing mechanism is connected to the liquid supply mechanism, the first liquid storage chamber is connected to the second liquid storage chamber through the liquid outlet, and a portion of the atomizing mechanism can release the locking connection between the piston and the retainer.

[0017] In some embodiments, the atomizing mechanism includes a top support configured to abut against the retainer or the piston when the atomizing mechanism is connected to the liquid supply mechanism, thereby releasing the engagement between the piston and the retainer.

[0018] In some embodiments, the liquid outlet is provided with a second seal, which has a cross opening or a straight opening;

[0019] The atomizing mechanism includes a liquid inlet that communicates with the second liquid storage chamber. When the atomizing mechanism is connected to the liquid supply mechanism, the wall of the liquid inlet passes through the second seal and is inserted into the liquid outlet.

[0020] In some embodiments, the liquid outlet is provided with a limiting member, and when the atomizing mechanism is connected to the liquid supply mechanism, the end of the liquid inlet abuts against the limiting member.

[0021] The liquid supply mechanism provided in this application embodiment, by setting a releasable retainer to cooperate with the drive member, allows the piston to directly compress the first liquid storage chamber after being released, so that the liquid matrix in the first liquid storage chamber can flow out quickly through the liquid outlet, thereby accelerating the liquid supply rate of the liquid supply mechanism.

[0043] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0044] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the external structure of the atomizing device in some embodiments of this application. Figure 2 yes Figure 1 A schematic diagram of the internal structure of the atomizing device in the embodiment.

[0045] This application provides an atomizing device, including an atomizing mechanism 20 and a liquid supply mechanism 10. The liquid supply mechanism 10 can deliver a liquid matrix to the atomizing mechanism 20, and the atomizing mechanism 20 can heat the liquid matrix to generate an aerosol for inhalation by a user.

[0046] The liquid supply mechanism 10 includes a housing 11, a piston 12, and a drive component 114.

[0047] The housing 11 has a first liquid storage chamber 111 for storing a liquid matrix, and the housing 11 has a liquid outlet 112 communicating with the first liquid storage chamber 111. The liquid matrix can specifically be a water-based solution, such as e-cigarette liquid containing nicotine, flavorings, etc. This type of water-based solution can be effectively converted into an aerosol by the atomizing mechanism 20 to meet the user's inhalation needs. Alternatively, it can be a liquid with medicinal ingredients, such as a solution containing medications for treating respiratory diseases, which can act directly on the affected area through the respiratory tract after atomization, achieving better therapeutic effects. It can also be a plant extract, such as extracts from peppermint or lemon, which can produce a unique aroma after atomization, bringing a different experience to the user.

[0048] The housing 11 is also provided with a retainer 113. The piston 12 is movably connected to the housing 11, and the piston 12 can cooperate with the retainer 113 and be locked in the retainer 113. The retainer 113 can keep the relative position of the piston 12 and the housing 11 fixed, and prevent the piston 12 from moving and causing leakage of liquid matrix when the liquid supply mechanism 10 is not in operation.

[0049] The drive member 114 is connected to the piston 12. The lock between the piston 12 and the retainer 113 can be released, and after release, the drive member 114 can drive at least part of the piston 12 to move toward the first liquid storage chamber 111 to compress the volume of the first liquid storage chamber 111 and thereby promote the flow of liquid matrix through the outlet 112.

[0050] The atomizing mechanism 20 includes a chamber 21, within which a second liquid storage chamber 211 is provided. When the atomizing mechanism 20 is connected to the liquid supply mechanism 10, the first liquid storage chamber 111 communicates with the second liquid storage chamber 211 through the liquid outlet 112, and a portion of the atomizing mechanism 20 can release the locking connection between the piston 12 and the retainer 113. When the piston 12 pushes the liquid matrix out of the first liquid storage chamber 111, it enters the atomizing mechanism 20. The second liquid storage chamber 211 of the atomizing mechanism 20 is provided with an atomizing core 22, which may include a ceramic heating element with good thermal conductivity and stability, capable of rapidly and uniformly heating the liquid matrix, causing it to quickly vaporize into an aerosol. Alternatively, the atomizing core 22 may include a metal heating wire, where heat is generated by an electric current passing through the heating wire to heat the liquid matrix.

[0051] In the liquid supply mechanism 10 provided in this embodiment, a releasable retainer 113 cooperates with a drive member 114, allowing the piston 12 to directly compress the first liquid storage chamber 111 after the constraint is released. The compression action of the piston 12 directly causes a change in the volume of the first liquid storage chamber 111, thereby increasing the air pressure in the first liquid storage chamber 111 and causing the liquid matrix to flow out. Compared with liquid supply methods that rely on gravity or capillary action, this method can more efficiently control the output rate of the liquid matrix, accelerate the liquid supply rate of the liquid supply mechanism 10, and reduce the risk of gelatinization of the atomizing core 22 due to untimely liquid supply.

[0052] Please see Figures 3 to 5 , Figure 3 yes Figure 1 A schematic diagram of the external structure of the liquid supply mechanism in the embodiment. Figure 4 yes Figure 1 A schematic diagram of the internal structure of the liquid supply mechanism when the piston and the retainer are engaged in the embodiment. Figure 5 yes Figure 1 A schematic diagram of the internal structure of the liquid supply mechanism when the piston and the retainer are disengaged in the embodiment.

[0053] In some embodiments, the piston 12 and the housing 11 together define a first liquid reservoir 111. The piston 12 and the housing 11 are tightly fitted to prevent the liquid matrix from leaking from the gap between the piston 12 and the housing 11, and the piston 12 is movable within the housing 11 to compress the first liquid reservoir 111.

[0054] In some embodiments, the piston 12 has a first position in which it is locked to the retainer 113, and a second position in which it is disengaged from the retainer 113; the volume of the first reservoir 111 partially defined when the piston 12 is in the first position is greater than the volume of the first reservoir 111 partially defined when the piston 12 is in the second position.

[0055] That is, after the piston 12 disengages from the retainer 113, the piston 12 can move from the first position to the second position under the action of the drive member 114. During the movement of the piston 12, the volume of the first liquid storage chamber 111 defined by the piston 12 and the housing 11 gradually decreases, causing the gas pressure in the first liquid storage chamber 111 to gradually increase, thereby causing the liquid matrix to flow out through the outlet 112.

[0056] In some embodiments, the retainer 113 may engage with the piston 12 via a snap-fit ​​connection. Exemplarily, the retainer 113 includes a snap-fit ​​portion 1131, and the piston 12 is provided with a snap-fit ​​engagement portion 122, the snap-fit ​​portion 1131 and the snap-fit ​​engagement portion 122 being snap-fit ​​connected.

[0057] The locking part 1131 can be a protruding structure or an elastic hook, and the locking mating part 122 can be a groove or a corresponding snap-fit ​​structure. The locking part 1131 and the locking mating part 122 can be made of plastic or metal, for example, an elastic arm can be provided on the retainer 113 to engage with a limiting groove on the piston 12. During installation, the snap-fit ​​structure achieves quick locking through elastic deformation. Different shapes of snap-fit ​​structures can be used, such as inclined guide snap-fits or rotary snap-fits, or the snap-fit ​​function can be achieved through the elastic deformation of the material. When releasing the retainer 113 from the piston 12, the two can be separated by moving the locking part 1131 or the locking mating part 122.

[0058] For example, such as Figure 4 As shown. In some embodiments, the retainer 113 further includes a cantilever portion 1132, which has a first end and a second end. A snap-fit ​​portion 1131 is disposed at the first end, and the second end can be driven to disengage the snap-fit ​​portion 1131 from the snap-fit ​​engagement portion 122. The cantilever portion 1132 in the retainer 113 is a structural component with elastic deformation capability. The cantilever portion 1132 and the snap-fit ​​portion 1131 can be integrally formed. The retainer 113 is made of metal or plastic and is formed by injection molding or machining.

[0059] Please combine Figure 6 and Figure 7 , Figure 6 yes Figure 1 A schematic diagram of the external structure of the atomizing mechanism in the embodiment. Figure 7 yes Figure 1 A schematic diagram of the internal structure of the atomizing mechanism in the embodiment.

[0060] The atomizing mechanism 20 includes a top holding portion 214, which is configured to abut against the retainer 113 when the atomizing mechanism 20 is connected to the liquid supply mechanism 10, thereby releasing the engagement between the piston 12 and the retainer 113. Specifically, when the atomizing mechanism 20 is connected to the liquid supply mechanism 10, the top holding portion 214 can act on the second end of the cantilever portion 1132, causing the locking portion 1131 to move away from the locking engagement portion 122, thereby separating the locking portion 1131 from the locking engagement portion 122.

[0061] Alternatively, in some embodiments, the piston 12 is further provided with a docking portion spaced apart from the snap-fit ​​portion 122, and the docking portion can be driven so that the snap-fit ​​portion 122 disengages from the snap-fit ​​portion 1131.

[0062] The top holding part 214 of the atomizing mechanism 20 can act on the docking part of the piston 12, and the docking part drives the snap-fit ​​part 122 to move, thereby separating the snap-fit ​​part 1131 from the snap-fit ​​part 122.

[0063] In some embodiments, the retainer 113 is not limited to engaging with the piston 12 via a snap-fit ​​connection; for example, the retainer 113 may be magnetically connected to the piston 12. Specifically, magnetic elements that attract each other are provided at the relative positions of the piston 12 and the retainer 113, and the piston 12 is magnetically attracted and fixed to the housing 11. The atomizing mechanism 20 includes magnetic elements with the same magnetic properties as the piston 12. When the atomizing mechanism 20 is connected to the liquid supply mechanism 10, the magnetic elements on the atomizing mechanism 20 repel the magnetic elements on the piston 12, thereby driving the piston 12 to disengage from the retainer 113 and move in the direction of compressing the first liquid storage chamber 111.

[0064] In some embodiments, the drive member 114 includes an elastic member, one end of which abuts against the piston 12 and the other end of which abuts against the housing 11.

[0065] An elastic element, acting as a driving component, is disposed between the piston 12 and the housing 11, providing driving force through elastic deformation. The elastic element includes, but is not limited to, helical springs, leaf springs, or elastic rubber materials. When the retainer 113 is connected to the piston 12, the elastic element is in a pre-compressed state. When the locking connection between the retainer 113 and the piston 12 is released, the elastic element releases potential energy, pushing the piston 12 to move, thereby compressing the wall of the first liquid storage chamber 111 and rapidly injecting the liquid matrix into the second liquid storage chamber 211. The compression amount of the elastic element can be adjusted according to the liquid supply requirements.

[0066] By using the pre-compression and release of elastic elements to form a mechanical energy storage device, the traditional passive gravity-driven liquid supply is converted into mechanical energy-driven operation, shortening the liquid matrix transmission time and avoiding the core-clogging problem caused by insufficient waiting time. The liquid supply speed can be flexibly controlled by adjusting the pre-compression amount of the elastic elements, ensuring both supply efficiency and reducing structural complexity.

[0067] Please see Figure 4 and Figure 5 In some embodiments, the piston 12 is provided with a receiving groove 121 extending in the moving direction, and at least part of the elastic element is provided in the receiving groove 121.

[0068] During the movement of piston 12, receiving groove 121 guides and limits the elastic element, ensuring that the elastic element remains stable when compressed or reset. For example, receiving groove 121 can be designed as an annular groove, with one end of the elastic element abutting against the bottom wall of receiving groove 121 and the other end abutting against housing 11.

[0069] By placing the elastic element within the receiving groove 121 of the piston 12, a precise fit between the elastic element and the piston 12 can be achieved, enabling the liquid supply mechanism 10 to obtain a more stable elastic support force when the piston 12 moves. Furthermore, this design saves installation space for the elastic element and improves the overall structural compactness.

[0070] In some embodiments, the housing 11 is provided with a guide 115 communicating with the first liquid storage chamber 111, the piston 12 is at least partially disposed in the guide 115, and the piston 12 is slidable in the guide 115 toward the first liquid storage chamber 111.

[0071] The guide member 115 is a hollow cylindrical structure. The cross-section of the guide member 115 can be designed as a circular ring or a rectangular ring, and the outer contour of the piston 12 is adapted to the inner contour of the guide member 115. By constraining the movement trajectory of the piston 12 through the guide member 115, the stability and sealing of the liquid delivery process are ensured.

[0072] In some embodiments, the housing 11 has opposing third and fourth ends, one end of the guide 115 is held on the third end of the housing 11, and the other end of the guide 115 extends into the first liquid reservoir 111 and is disposed near the fourth end of the housing 11. When the piston 12 slides in the guide 115 toward the first liquid reservoir 111, it can be confined by the fourth end of the housing 11 to prevent it from disengaging from the guide 115.

[0073] The guide 115 and the retainer 113 can be designed as an integral structure, thereby improving the integrity of the liquid supply mechanism 10 and reducing the number of parts to be assembled.

[0074] Please continue reading. Figure 4 and Figure 5 In some embodiments, the liquid supply mechanism 10 further includes a first seal 14 disposed between the outer side wall of the piston 12 and the inner side wall of the guide 115. The first seal 14 may be made of an elastic material, such as rubber or silicone, and is disposed in the contact area between the piston 12 and the guide 115 by an embedded installation or interference fit.

[0075] By setting the first seal 14, leakage of the liquid matrix can be effectively prevented, thus improving the sealing performance of the liquid supply mechanism 10. The blocking effect of the first seal 14 ensures the instantaneous liquid supply efficiency when the elastic element is released, avoiding problems such as liquid supply delay or insufficient pressure caused by liquid leakage.

[0076] Understandably, the first seal 14 may be part of the housing 11. Specifically, the seal may be fixed to the inner wall of the guide 115, and the piston 12 moves relative to the first seal 14 as the piston 12 moves relative to the housing 11.

[0077] Alternatively, the first seal 14 can also be part of the piston 12. The first seal 14 is an O-ring, and the piston 12 moves synchronously with the first seal 14.

[0078] Please see Figures 5 to 7 In some embodiments, the liquid outlet 112 is provided with a second seal 13, which has a cross opening or a straight opening.

[0079] The chamber 21 has a liquid inlet 212 that communicates with the second liquid storage chamber 211. When the atomizing mechanism 20 is connected to the liquid supply mechanism 10, the wall of the liquid inlet 212 passes through the second seal 13 and is inserted into the liquid outlet 112.

[0080] The opening structure of the second seal 13 allows the liquid inlet 212 to pass through while maintaining the seal between the liquid inlet 212 and the second seal 13, ensuring rapid transfer of the liquid matrix under pressure. In a specific embodiment, the second seal 13 can be a sealing component made of silicone or rubber, and the liquid inlet 212 can be a tubular structure made of metal or plastic.

[0081] In some embodiments, the outlet 112 is provided with a limiting member 15. When the atomizing mechanism 20 and the liquid supply mechanism 10 are connected in place, the end of the inlet hole 212 abuts against the limiting member 15. The limiting member 15 can limit the depth of the inlet hole 212 inserted into the outlet 112, avoiding the impact on the liquid matrix transmission effect due to excessive or shallow insertion. For example, if the inlet hole 212 is inserted too deeply, it may cause the liquid transmission channel to be obstructed or even blocked; if it is inserted too shallowly, it may not be able to guarantee good sealing, resulting in leakage.

[0082] Please see Figure 4 In some embodiments, the liquid outlet 112 and the piston 12 are located at different positions on the housing 11. For example, the liquid outlet 112 is located near the bottom of the housing 11, and the piston 12 is located near the top of the housing 11. When the piston 12 compresses the space of the first liquid storage chamber 111, the liquid matrix flows into the second liquid storage chamber 211 under the push of the piston 12 and the action of gravity, effectively improving the flow rate of the liquid matrix.

[0083] In some embodiments, the liquid outlet 112 and the piston 12 are located at the same position on the housing 11. For example, the liquid outlet 112 is disposed on or adjacent to the retainer 113. When the piston 12 is locked, it can simultaneously seal the liquid outlet 112. The wall of the liquid inlet 212 in the atomizing mechanism 20 can serve as a pusher for unlocking, so that when the atomizing mechanism 20 is connected to the liquid supply mechanism 10, the locking state of the piston 12 can be released and the liquid outlet 112 can be opened.

[0084] When the atomizing mechanism 20 is connected to the liquid supply mechanism 10, the wall of the liquid inlet 212 can also be inserted into the piston 12. A sealing structure is provided between the outer wall of the liquid inlet 212 and the inner wall of the piston 12, so that the liquid inlet 212 and the liquid outlet 112 are in a sealed communication.

[0085] Please see Figure 7 In some embodiments, the second liquid storage chamber 211 is further provided with a liquid storage component 23, which covers the periphery of the atomizing core 22 to guide the liquid matrix into the atomizing core 22. The liquid storage component 23 is not limited to being made of porous materials that easily absorb water, such as fibers or cotton cores.

[0086] In some embodiments, the liquid storage component 23 has a chamfered surface 231, which faces the end side of the liquid inlet 212, and the chamfered surface 231 is inclined from the inner wall of the second liquid storage cavity 211 in a direction away from the liquid inlet 212. It is understood that the liquid inlet 212 not only serves to transport the liquid matrix between the first liquid storage cavity 111 and the second liquid storage cavity 211, but also enables air exchange between them. During the operation of the atomizing device, the liquid storage component 23 is prone to thermal expansion, and the chamfered surface 231 of the liquid storage component 23 does not completely fit the inner wall of the second liquid storage cavity 211, meaning that the liquid storage component 23 does not completely fill the second liquid storage cavity 211. The portion of the liquid storage component 23 near the liquid inlet 212 has ample expansion space to prevent the liquid storage component 23 from blocking the liquid inlet 212 when it expands due to heat, thus affecting the liquid supply rate and air exchange efficiency of the first liquid storage chamber 111 and the second liquid storage chamber 211.

[0087] Please combine Figure 7 and Figure 8 , Figure 8 yes Figure 1 A partial structural diagram of the atomizing mechanism in the embodiment. An air exchange groove 213 is provided on the inner wall of the second liquid storage chamber 211. The air exchange groove 213 extends along the length direction of the atomizing mechanism 20 to balance the air pressure at the upper and lower ends of the second liquid storage chamber 211.

[0088] At least a portion of the ventilation groove 213 is located between the oblique surface 231 and the inner wall of the second liquid storage chamber 211, and the ventilation groove 213 communicates with the liquid inlet 212. When the liquid matrix flows into the second liquid storage chamber 211 from the liquid outlet 112 and is absorbed by the liquid storage component 23, due to the presence of the ventilation groove 213, the air in the second liquid storage chamber 211 can be replenished to the first liquid storage chamber 111 in a timely manner through the ventilation groove 213 and the liquid inlet 212, maintaining the air pressure balance between the first liquid storage chamber 111 and the second liquid storage chamber 211. In practical applications, the number of ventilation grooves 213 can be reasonably set according to the size of the second liquid storage chamber 211 and the working requirements of the atomizing mechanism 20.

[0089] The above description is only a part of the embodiments of this application and does not limit the scope of protection of this application. Any equivalent device or equivalent process transformation made based on the content of this application specification and drawings, or direct or indirect application in other related technical fields, are similarly included in the patent protection scope of this application.
