The liquid continuation mechanism comprises a shell, a pressurizing piece and a first movable piece. The shell is provided with a first liquid storage cavity. The pressurizing piece is configured to be driven to increase the pressure of the first liquid storage cavity. The first movable piece is used to close a liquid delivery channel communicated with the first liquid storage cavity.

Description

Technical Field

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

[0002] Atomizers are electronic products that heat a liquid matrix and convert it into an aerosol through an internal atomizing component for users to inhale. Current atomizing devices rely on a continuous liquid supply mechanism to the atomizing unit during inhalation, making it difficult to effectively control the amount of liquid matrix output from the supply mechanism. This can easily lead to a large amount of liquid matrix remaining in the atomizing unit and causing leakage. Utility Model Content

[0003] This application provides a liquid replenishment mechanism and an atomizing device to solve the problem of not being able to effectively control the amount of liquid matrix output by the liquid replenishment mechanism.

[0004] On one hand, embodiments of this application provide a fluid replenishment mechanism, including a housing, a pressurizing member, and a first movable member. The housing is provided with a first liquid storage chamber for storing a liquid matrix. The pressurizing member is configured to be driven to increase the pressure in the first liquid storage chamber. The first movable member is used to close a delivery channel communicating with the first liquid storage chamber. When the pressure in the first liquid storage chamber increases, the first movable member can move relative to the housing under the pressure to open the delivery channel and output a preset amount of liquid matrix through the delivery channel. After outputting the preset amount of liquid matrix, the first movable member can move relative to the housing again to return to the state of closing the delivery channel.

[0005] In some embodiments, the pressurizing member is configured to move relative to the housing toward the first liquid reservoir or extend into the first liquid reservoir to compress the volume of the first liquid reservoir, thereby increasing the pressure in the first liquid reservoir.

[0006] In some embodiments, the pressurizing element is independent of the housing or the pressurizing element is part of the housing.

[0007] In some embodiments, the pressurizing member and the housing together define at least a portion of the boundary of the first liquid reservoir.

[0008] In some embodiments, the housing defines an inlet, an outlet, and a connecting channel extending from the inlet to the outlet, the connecting channel forming the infusion channel; The first movable element closes the inlet to close the infusion channel, and opens the inlet to open the infusion channel when it moves relative to the housing.

[0009] In some embodiments, the first movable member includes a first blocking component disposed in the connection channel and closing the inlet. When the first movable member moves relative to the housing, the first blocking component moves toward the outlet or away from the inlet to open the inlet.

[0010] In some embodiments, the first movable element further includes a first sealing member disposed in the connection channel, the first sealing member being at least partially sandwiched between the first sealing member and the inlet.

[0011] In some embodiments, the diameter of the inlet gradually decreases along the direction from the inlet to the outlet.

[0012] In some embodiments, the housing defines an inlet, an outlet, and a connecting channel extending from the inlet to the outlet, the first movable member closes the outlet and is provided with a through hole, and the infusion channel extends from the inlet to the through hole; Before the first movable member moves relative to the housing, the through hole is hidden in the connection channel to close the infusion channel; when the first movable member moves relative to the housing, the through hole is exposed outside the connection channel to open the infusion channel.

[0013] In some embodiments, the first movable member includes a second blocking member disposed in the connection channel, wherein the end of the second blocking member near the inlet is an open end and the other end of the second blocking member near the outlet is a closed end, and the through hole is provided on the side wall of the second blocking member.

[0014] In some embodiments, the first movable member further includes a second sealing member disposed outside the connection channel and at least partially sandwiched between the closed end of the second sealing member and the outlet.

[0015] In some embodiments, the liquid replenishment mechanism further includes a first reset member, which provides a restoring force after outputting a preset amount of liquid matrix to drive the first movable member to move relative to the housing again.

[0016] In some embodiments, the fluid replenishment mechanism further includes a control element at least partially exposed outside the housing, the control element being operable to drive the first movable element to open or close the infusion channel.

[0017] In some embodiments, the control member includes a pressing member connected to the first movable member, and the fluid replenishment mechanism further includes a second reset member; When the pressing member is pressed, it can drive the first movable member to move relative to the housing to open the infusion channel; and when the pressing operation is released, the second reset member can provide a restoring force to drive the first movable member to move relative to the housing again and return to the state of closing the infusion channel.

[0018] In some embodiments, the control member includes a second movable member that is movable relative to the housing, the second movable member including a first magnetic member, and the first movable member including a second magnetic member and a third reset member; When the second movable component moves to the first position relative to the housing, the magnetic force between the first magnetic component and the second magnetic component can drive the first movable component to move relative to the housing, thereby opening the infusion channel; When the second movable member moves to the second position relative to the housing, the third reset member can provide a restoring force to drive the first movable member to move again relative to the housing and return to the state of closing the infusion channel.

[0019] In some embodiments, the housing defines an inlet, an outlet, and a connecting channel extending from the inlet to the outlet, the connecting channel forming the infusion channel, and the first movable member closes the inlet to close the infusion channel; The liquid replenishment mechanism also includes a seal disposed at the outlet, which can be punctured or removed; when the seal has not been punctured or removed and the control member drives the first movable member to open the inlet, the liquid matrix flowing out of the first liquid storage chamber through the inlet is temporarily stored in the connecting channel.

[0020] On the other hand, an atomizing device is provided, including a liquid replenishing mechanism as described in any of the above embodiments and an atomizing mechanism independent of the liquid replenishing mechanism; the atomizing mechanism includes a second liquid storage chamber and an atomizing core; wherein, when the atomizing mechanism is combined with the liquid replenishing mechanism, the second liquid storage chamber is connected to the first liquid storage chamber through the liquid delivery channel, and the atomizing mechanism is capable of driving the pressurizing member to allow a preset amount of liquid matrix to flow into the second liquid storage chamber.

[0021] The refill mechanism and atomizing mechanism provided in this embodiment are independent of each other. Before the atomizing mechanism is used, the liquid matrix in the refill mechanism can be kept separate from the atomizing core, thereby avoiding damage to the atomizing core caused by prolonged immersion of the liquid matrix and preventing any impact on the flavor of the liquid matrix. When the atomizing mechanism is combined with the refill mechanism, it directly drives the pressurizing component to increase the pressure in the first liquid storage chamber. Without additional user operation, the liquid matrix can quickly flow into the second liquid storage chamber through the pressurizing component, thereby wetting the atomizing core for quick use. In addition, since the first movable component in the refill mechanism can return to the closed state after opening the infusion channel, the amount of liquid matrix output by the refill mechanism at one time is controllable, preventing excessive liquid matrix from remaining in the atomizing mechanism and reducing the risk of liquid matrix leakage.

[0026] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application. Similarly, the following embodiments are only some, not all, embodiments of the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

[0027] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the atomizing device assembly in some embodiments of this application. Figure 2 yes Figure 1 A schematic diagram of the structure of the atomizing device without assembly in the embodiment.

[0028] This application provides an atomizing device 1000, including a liquid replenishment mechanism 100 and an atomizing mechanism 200 independent of the liquid replenishment mechanism 100. The liquid replenishment mechanism 100 includes a housing 11, a pressurizing member 14, and a first movable member 12. The housing 11 is provided with a first liquid storage chamber 111 for storing a liquid matrix; the pressurizing member 14 is configured to be driven to increase the pressure of the first liquid storage chamber 111; the first movable member 12 is used to close the infusion channel 112 communicating with the first liquid storage chamber 111. When the pressure of the first liquid storage chamber 111 increases, the first movable member 12 can move relative to the housing 11 under the pressure of the first liquid storage chamber 111 to open the infusion channel 112 and output a preset amount of liquid matrix through the infusion channel 112; and after outputting the preset amount of liquid matrix, the first movable member 12 can move relative to the housing 11 again to return to the state of closing the infusion channel 112.

[0029] When the first movable member 12 closes the infusion channel 112, it is in the closed position relative to the housing 11; when the first movable member 12 opens the infusion channel 112, it is in the open position relative to the housing 11. When the first movable member 12 closes the infusion channel 112, it is held in the closed position by the pressure of the liquid matrix and external forces. When the driving member increases the pressure in the first liquid storage chamber 111, the first movable member 12 moves relative to the housing 11 to the open position under the pressure of the first liquid storage chamber 111, thereby opening the infusion channel 112 and outputting the liquid matrix. As the liquid matrix is ​​output, the pressure in the first liquid storage chamber 111 gradually decreases, causing the external force on the first movable member 12 to exceed the pressure of the liquid matrix, thus causing the first movable member 12 to move relative to the housing 11 back to the closed position, stopping the continuous output of liquid matrix by the replenishing mechanism 100. It is understandable that the process between the first movable part 12 opening the infusion channel 112 and closing the infusion channel 112 again is the working stage of the liquid replenishment mechanism 100 outputting liquid matrix. During this process, a preset amount of liquid matrix is ​​output. The preset amount can be a fixed value (i.e., a quantitative amount) or a variable value within a preset range. Here, it only means that the amount of liquid matrix output by the liquid replenishment mechanism 100 is controllable, and no specific value is limited.

[0030] Please see Figures 1 to 4 , Figure 3 This is a schematic diagram of the atomizing device during assembly in another embodiment. Figure 4 yes Figure 3This is a schematic diagram of the atomizing device without assembly in the embodiment. In some embodiments, the replenishing mechanism 100 can be attached to the atomizing mechanism 200 along its width or length, and can also be detached or removed from the atomizing mechanism 200. When the replenishing mechanism 100 is attached to the atomizing mechanism 200, it can replenish the liquid matrix to the atomizing mechanism 200; the replenishing mechanism 100 is replaceable, while the atomizing mechanism 200 is reusable; after the liquid matrix in the replenishing mechanism 100 is replenished, the user can detach and replace it with a new replenishing mechanism 100 from the atomizing mechanism 200. Alternatively, in some variations, once the replenishing mechanism 100 is attached to the atomizing mechanism 200, it cannot be detached from the atomizing mechanism 200; after the liquid matrix inside is consumed, it is recycled or discarded as a whole.

[0031] The atomizing mechanism 200 includes a second liquid storage chamber 21 and an atomizing core 23. The atomizing core 23 is disposed within the second liquid storage chamber 21 and is used to heat the liquid matrix and generate an aerosol. When the atomizing mechanism 200 is combined with the liquid replenishment mechanism 100, the second liquid storage chamber 21 is connected to the first liquid storage chamber 111 via the liquid delivery channel 112, and the atomizing mechanism 200 can drive the pressurizing member 14 to allow a preset amount of liquid matrix to flow into the second liquid storage chamber 21.

[0032] The second liquid storage chamber 21 is further provided with a liquid holding element 26, which is made of flexible or rigid porous material or fiber material, to adsorb and retain the liquid matrix stored in the first liquid storage chamber 111; the liquid holding element 26 and / or the second liquid storage chamber 21 are basically annular in shape, and the liquid holding element 26 surrounds the outer periphery of the atomizing core 23 to uniformly supply liquid to the atomizing core 23. In some embodiments, the liquid holding element 26 may also include a rigid porous material such as porous ceramic or porous glass, or it may also include flexible porous fibers such as porous cotton fibers, porous nonwoven fabric or porous sponge.

[0033] The atomizing mechanism 200 includes a housing 24 and several components disposed within the housing 24. The overall design of the housing 24 is variable, and the type or configuration of the housing 24 that defines the overall size and shape of the atomizing mechanism 200 is also variable. Typically, the housing 24 may be formed from a single integral housing 11, or the housing 24 may be formed from two or more separable bodies. In some examples, all or only part of the housing 24 may be formed from a metal or alloy such as stainless steel or aluminum, or other suitable materials including various plastics (e.g., polycarbonate), metal-plating over plastic, ceramics, etc.

[0034] like Figure 2 and Figure 4As shown, the outer casing 24 is generally constructed in an L-shape. When the replenishing mechanism 100 is attached to the atomizing mechanism 200, the replenishing mechanism 100 abuts against the first side 241 and the second side 242 of the L-shaped outer casing 24, wherein the first side 241 extends along the length direction and the second side 242 extends along the width direction, the first side 241 and the second side 242 are adjacent to each other and form an assembly space between them to accommodate the replenishing mechanism 100.

[0035] The outer casing 24 has a first side 241 or a second side 242 with an insertion interface 25 adapted to the infusion channel 112 of the liquid replenishment mechanism 100. This interface can be inserted into the infusion channel 112 when the liquid replenishment mechanism 100 is attached to the atomizing mechanism 200 to prevent liquid matrix leakage. Optionally, a liquid guiding element 27 is provided within the insertion interface 25. In this embodiment, this element is flexible, for example, made of flexible fibers such as cotton fibers, non-woven fabric, or sponge. Alternatively, in some variations, the liquid guiding element 27 may include a rigid porous element, such as porous ceramic or porous glass. The outer surface of the liquid guiding element 27 is in fluid communication with the liquid holding element 26 and the first liquid storage chamber 111. The outer surface of the liquid guiding element 27 is used to draw liquid matrix from the first liquid storage chamber 111 and transfer the liquid matrix to the liquid holding element 26, which then supplies liquid to the internal atomizing core 23.

[0036] The terms "first," "second," and "third" used in the embodiments of this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," and "third" may explicitly or implicitly include at least one of those features.

[0037] In this embodiment, since the replenishing mechanism 100 and the atomizing mechanism 200 are independent of each other, the atomizing core 23 can be kept separate from the liquid matrix in the replenishing mechanism 100 before the atomizing mechanism 200 is used. This avoids damage to the atomizing core 23 caused by prolonged immersion of the liquid matrix in the atomizing core 23, and also avoids affecting the taste of the liquid matrix. When the atomizing mechanism 200 is combined with the replenishing mechanism 100, it directly drives the pressurizing member 14 to increase the pressure in the first liquid storage chamber 111. Without additional user operation, the liquid matrix can quickly flow into the second liquid storage chamber 21 through the pressurizing member 14, thereby wetting the atomizing core 23 for quick use by the user. In addition, since the first movable member 12 in the replenishing mechanism 100 can return to the closed state after opening the infusion channel 112, the amount of liquid matrix that the replenishing mechanism 100 adds to the atomizing mechanism 200 at one time is controllable, preventing excessive liquid matrix from remaining in the atomizing mechanism 200 and reducing the risk of liquid matrix leakage.

[0038] In some embodiments, the pressurizing member 14 is configured to move relative to the housing 11 toward the first liquid storage chamber 111 or extend into the first liquid storage chamber 111 to compress the volume of the first liquid storage chamber 111, thereby increasing the pressure of the first liquid storage chamber 111.

[0039] like Figure 1 and Figure 2 As shown, in one specific embodiment, the housing 11 is further provided with a retaining member 116. The pressurizing member 14 is movably connected to the housing 11, and the pressurizing member 14 can cooperate with the retaining member 116 and be locked in place by the retaining member 116. The retaining member 116 can keep the relative position of the pressurizing member 14 and the housing 11 fixed, preventing the liquid matrix from leaking due to the movement of the pressurizing member 14 when the liquid replenishment mechanism 100 is not in operation. The pressurizing member 14 and the housing 11 together define the first liquid storage chamber 111. The pressurizing member 14 and the housing 11 are tightly fitted to prevent the liquid matrix from leaking from the gap between the pressurizing member 14 and the housing 11, and the pressurizing member 14 can move within the housing 11 to compress the first liquid storage chamber 111.

[0040] When the atomizing mechanism 200 is connected to the replenishing mechanism 100, a portion of the atomizing mechanism 200 can release the locking connection between the pressurizing member 14 and the retaining member 116. After the pressurizing member 14 pushes the liquid matrix out of the first liquid storage chamber 111, it will enter the atomizing mechanism 200.

[0041] For example, the retainer 116 can engage with the pressure member 14 via a snap-fit ​​connection. Specifically, the retainer 116 includes a snap-fit ​​portion 1161, and the pressure member 14 has a snap-fit ​​mating portion 141, with the snap-fit ​​portion 1161 and the snap-fit ​​mating portion 141 snap-fitted together. The snap-fit ​​portion 1161 can be a protruding structure or an elastic hook, and the snap-fit ​​mating portion 141 can be a groove or a corresponding snap-fit ​​structure. The snap-fit ​​portion 1161 and the snap-fit ​​mating portion 141 can be made of plastic or metal. During installation, the snap-fit ​​structure achieves quick locking through elastic deformation. Different shapes of snap-fit ​​structures can be used, such as beveled guide snap-fits or rotating snap-fits, or the snap-fit ​​function can be achieved through the elastic deformation of the material.

[0042] Such as 1 and Figure 2As shown, in some embodiments, the atomizing mechanism 200 includes a first supporting portion 22, which is configured to abut against the retainer 116 when the atomizing mechanism 200 is connected to the liquid replenishment mechanism 100, thereby releasing the engagement between the pressure member 14 and the retainer 116. Specifically, when the atomizing mechanism 200 and the liquid replenishment mechanism 100 are engaged, the first supporting portion 22 can move the locking portion 1161 or the locking engagement portion 141 to separate them, thereby releasing the locking connection between the retainer 116 and the pressure member 14. Optionally, the first supporting portion 22 and the insertion interface 25 may be spaced apart on the same side of the housing 24, such as the first side 241 or the second side 242.

[0043] like Figure 3 and Figure 4 As shown, in some embodiments, the first supporting portion 22 is configured to abut against the pressurizing member 14 when the atomizing mechanism 200 is connected to the replenishing mechanism 100, and drive the pressurizing member 14 to move into the first liquid storage chamber 111. During the movement of the pressurizing member 14, the locking engagement portion 141 moves relative to the locking portion 1161, thereby releasing the locking connection between the retaining member 116 and the pressurizing member 14. Optionally, the first supporting portion 22 and the insertion interface 25 are disposed in the same position. The first supporting portion 22 can be reused as the insertion interface 25. For example, the pressurizing member 14 forms at least a portion of the infusion channel 112, the first supporting portion 22 is inserted into the infusion channel 112 and communicates with the first liquid storage chamber 111, and the first supporting portion 22 abuts against the pressurizing member 14 within the infusion channel 112.

[0044] It is understood that the retainer 116 is not limited to engaging with the pressure member 14 via a snap-fit ​​connection; for example, the retainer 116 can be magnetically connected to the pressure member 14. Specifically, magnetic elements that attract each other are provided at the relative positions of the pressure member 14 and the retainer 116, and the pressure member 14 is magnetically attracted and fixed to the housing 11. The atomizing mechanism 200 includes magnetic elements with the same magnetic properties as the pressure member 14. When the atomizing mechanism 200 is connected to the liquid replenishment mechanism 100, the magnetic elements on the atomizing mechanism 200 and the magnetic elements on the pressure member 14 repel each other, thereby driving the pressure member 14 to detach from the retainer 116 and move in the direction of compressing the first liquid storage chamber 111.

[0045] like Figure 1 and Figure 2As shown, in some embodiments, a first elastic member 142 is provided between the pressurizing member 14 and the housing 11. The locking between the pressurizing member 14 and the retaining member 116 can be released, and after release, the first elastic member 142 can drive at least a portion of the pressurizing member 14 to move into the first liquid storage chamber 111, thereby compressing the volume of the first liquid storage chamber 111. That is, the pressurizing member 14 has a locked position where it is locked to the retaining member 116, and an unlocked position where it is disengaged from the retaining member 116. When the pressurizing member 14 is disengaged from the retaining member 116, it can move from the locked position to the unlocked position under the action of the first elastic member 142. During the movement of the pressurizing member 14, the volume of the first liquid storage chamber 111 defined by the pressurizing member 14 and the housing 11 gradually decreases, causing the air pressure in the first liquid storage chamber 111 to gradually increase.

[0046] The first elastic element 142, acting as a driving component, is disposed between the pressure member 14 and the housing 11, providing driving force through elastic deformation. The first elastic element 142 includes, but is not limited to, a coil spring, a leaf spring, or an elastic rubber material. When the retainer 116 is connected to the pressure member 14, the elastic element is in a pre-compressed state. When the locking connection between the retainer 116 and the pressure member 14 is released, the elastic element releases potential energy, pushing the pressure member 14 to move, thereby compressing the first liquid storage chamber 111 and rapidly injecting the liquid matrix into the second liquid storage chamber 21. The compression amount of the elastic element can be adjusted according to the liquid supply requirements.

[0047] Alternatively, the first movable member 12 can be set independently of the pressurizing member 14. The pressurizing member 14 moves into the first liquid storage chamber 111, thereby compressing the volume of the first liquid storage chamber 111 and increasing the pressure inside the first liquid storage chamber 111. The liquid matrix further transmits the pressure to the first movable member 12, thereby driving the first movable member 12 to move and open the infusion channel 112.

[0048] Please see Figure 3 and Figure 4 Optionally, the first movable member 12 can be directly mounted on the pressurizing member 14, and the infusion channel 112 is also mounted on the pressurizing member 14. As the pressurizing member 14 moves into the first liquid storage chamber 111, it drives the first movable member 12 to move synchronously, thereby increasing the pressure in the first liquid storage chamber 111. When the pressure in the first liquid storage chamber 111 is greater than other external forces acting on the first movable member 12, the first movable member 12 moves relative to the pressurizing member 14 and opens the infusion channel 112.

[0049] In this embodiment, to ensure the stable position of the pressurizing member 14 relative to the housing 11 after the atomizing mechanism 200 and the liquid replenishing mechanism 100 are combined, two snap-fit ​​positions are provided between the pressurizing member 14 and the housing 11. For example, the housing 11 is provided with two snap-fit ​​portions 1161, and the two snap-fit ​​portions 1161 are spaced apart along the moving direction of the pressurizing member 14 relative to the housing 11. The pressurizing member 14 is provided with a snap-fit ​​mating portion 141. When the liquid replenishing mechanism 100 is independent, the snap-fit ​​mating portion 141 on the pressurizing member 14 snaps with one of the snap-fit ​​portions 1161. When the liquid replenishing mechanism 100 is combined with the atomizing mechanism 200, the atomizing mechanism 200 releases the connection between the snap-fit ​​mating portion 141 and the snap-fit ​​portion 1161, and drives the pressurizing member 14 to move into the first liquid storage chamber 111 until it snaps with the other snap-fit ​​portion 1161. At this time, the liquid replenishing mechanism 100 and the atomizing mechanism 200 are assembled in place. Of course, in other embodiments, the housing 11 may also have a snap-fit ​​portion 1161, and the pressure member 14 may have multiple snap-fit ​​mating portions 141 spaced apart, or the housing 11 and the pressure member 14 may each have multiple corresponding snap-fit ​​portions 1161 and snap-fit ​​mating portions 141. In this way, during the user's suction process, the position of the pressure member 14 can remain stable relative to the housing 11, thereby preventing the first movable member 12 from moving relative to the housing 11 under pressure changes in the first liquid storage chamber 111, causing the pressure member 14 to move synchronously, resulting in unstable liquid supply.

[0050] In one specific embodiment, a second elastic member (not shown) is provided between the pressurizing member 14 and the housing 11. The pressurizing member 14 and the housing 11 together define the first liquid storage cavity 111, and the pressurizing member 14 and the housing 11 are movably connected. The atomizing mechanism 200 includes a second supporting portion. The second elastic member provides a force to the pressurizing member 14 to move away from the first liquid storage cavity 111. A limiting structure is provided on the housing 11 to limit the pressurizing member 14 from moving excessively away from the first liquid storage cavity 111 under the force of the second elastic member. When the replenishing mechanism 100 is independent, the pressurizing member 14 abuts against the limiting structure under the action of the second elastic member, so that the initial volume of the first liquid storage cavity 111 remains stable. When the liquid replenishment mechanism 100 is combined with the atomizing mechanism 200, the second top holding part of the atomizing mechanism 200 will apply a thrust to the pressurizing member 14 toward the first liquid storage chamber 111. This thrust overcomes the force of the second elastic member and causes the pressurizing member 14 to move toward the first liquid storage chamber 111, thereby compressing the volume of the first liquid storage chamber 111.

[0051] In one specific embodiment, the pressure-applying member 14 can be a deformable sealing structure communicating with the first liquid storage chamber 111. By squeezing the pressure-applying member 14, the pressure inside the first liquid storage chamber 111 increases. For example, the pressure-applying member 14 is a compression nozzle independent of the housing 11; or the pressure-applying member 14 is part of the housing 11, and the pressure inside the first liquid storage chamber 111 can be increased by pressing the housing 11. When the atomizing mechanism 200 is combined with the liquid replenishment mechanism 100, the atomizing mechanism 200 partially squeezes the pressure-applying member 14.

[0052] In some embodiments, the pressurizing member 14 and the housing 11 together define at least a portion of the boundary of the first liquid reservoir 111. Thus, by driving the movement or deformation of the pressurizing member 14, the boundary of the first liquid reservoir 111 is changed, thereby changing the volume of the first liquid reservoir 111 and consequently changing the pressure within the first liquid reservoir 111.

[0053] Please see Figure 1 and Figure 2 In some embodiments, the housing 11 defines an inlet 113, an outlet 115, and a connecting channel 114 extending from the inlet 113 to the outlet 115, the connecting channel 114 forming an infusion channel 112; a first movable member 12 closes the inlet 113 to close the infusion channel 112, and opens the inlet 113 to open the infusion channel 112 when movable relative to the housing 11. The inlet 113 communicates with a first liquid storage chamber 111, and the outlet 115 can communicate with a second liquid storage chamber 21 in the atomizing mechanism 200.

[0054] In some embodiments, the first movable member 12 includes a first blocking member 121 disposed in the connection channel 114 and closing the inlet 113. When the first movable member 12 moves relative to the housing 11, the first blocking member 121 moves toward the outlet 115 or away from the inlet 113 to open the inlet 113.

[0055] Specifically, the diameter of the connecting channel 114 is larger than the diameter of the inlet 113, and there is a gap between the first sealing component 121 and the inner wall of the connecting channel 114. When the first sealing component 121 closes the inlet 113 of the connecting channel 114, the first sealing component 121 covers the inlet 113, thereby blocking the liquid matrix from flowing into the connecting channel 114 through the inlet 113; during the process of the first sealing component 121 opening the inlet 113, the first sealing component 121 is moved away from the inlet 113 or towards the outlet 115 by the pressure of the liquid matrix, thereby forming a gap between the first sealing component 121 and the inlet 113, and allowing the liquid matrix to flow into the connecting channel 114 through the gap.

[0056] In some embodiments, the first movable member 12 further includes a first sealing member 122 disposed in the connection channel 114, the first sealing member 122 being at least partially sandwiched between the first blocking member 121 and the inlet 113.

[0057] The first sealing component 122 is made of, but is not limited to, easily compressible materials such as rubber or silicone. The first sealing component 122 is sandwiched between the first sealing component 121 and the inlet 113 to provide a seal between the first sealing component 121 and the portion of the housing 11 that defines the inlet 113 when the first sealing component 121 closes the inlet 113, thereby preventing leakage of the liquid matrix.

[0058] In some embodiments, the diameter of the inlet 113 gradually decreases along the direction from the inlet 113 to the outlet 115.

[0059] Understandably, when inlet 113 is opened, the liquid matrix gradually flows from inlet 113 into connecting channel 114 along the direction from inlet 113 to outlet 115. Therefore, the diameter of inlet 113 is set to gradually decrease along the flow direction of the liquid matrix. Thus, when the liquid matrix flows in from the large-diameter end of inlet 113, as the cross-section of inlet 113 gradually contracts along the flow direction, the flow velocity of the liquid matrix will significantly increase due to the narrowing of the channel, thereby quickly passing through inlet 113 into connecting channel 114 and moving towards outlet 115. At the same time, the increase in flow velocity will strengthen the impact of the liquid matrix on the first sealing component 121, enabling the first sealing component 121 to overcome the initial resistance and move away from inlet 113 more quickly during the opening process, avoiding slow opening or unstable flow due to insufficient pressure.

[0060] Please see Figure 3 and Figure 4 In some embodiments, the housing 11 defines an inlet 113, an outlet 115, and a connecting channel 114 extending from the inlet 113 to the outlet 115, with the first movable member 12 closing the outlet 115. The inlet 113 communicates with the first liquid storage chamber 111, and the outlet 115 communicates with the second liquid storage chamber 21 in the atomizing mechanism 200. The first movable member 12 is provided with a through hole 125, and the infusion channel 112 extends from the inlet 113 to the through hole 125. Before the first movable member 12 moves relative to the housing 11, the through hole 125 is hidden in the connecting channel 114 to close the infusion channel 112; when the first movable member 12 moves relative to the housing 11, the through hole 125 is exposed outside the connecting channel 114 to open the infusion channel 112.

[0061] Specifically, the first movable member 12 can be slidably disposed in the housing 11 along the axial direction of the connecting channel 114. Before the first movable member 12 moves relative to the housing 11, the through hole 125 is completely covered by the inner wall of the connecting channel 114, and the liquid matrix cannot enter the outlet 115 side through the through hole 125. When the first movable member 12 is subjected to the impact pressure of the liquid matrix and moves axially toward the outlet 115, the through hole 125 moves synchronously with it. Subsequently, the hole wall of the through hole 125 is removed from the inner wall covered area of ​​the connecting channel 114 from the outlet 115 side, and the through hole 125 is gradually exposed in the space communicating with the outlet 115. At this time, the liquid matrix can enter the second liquid storage chamber 21 in sequence through the inlet 113, the connecting channel 114, and the through hole 125, thereby realizing the smooth opening of the infusion channel 112.

[0062] In some embodiments, the first movable member 12 includes a second blocking member 123 disposed in the connecting channel 114. The end of the second blocking member 123 near the inlet 113 is an open end 123a, and the other end of the second blocking member 123 near the outlet 115 is a closed end 123b. A through hole 125 is provided on the side wall of the second blocking member 123.

[0063] like Figure 4 As shown, the second sealing component 123 is a hollow cylindrical structure, such as a cylinder or square tube. The open end 123a of the second sealing component 123 allows fluid to enter the second sealing component 123, while the closed end 123b of the second sealing component 123 blocks the entry and exit of fluid, so that when the first movable component 12 is separated from the atomizing mechanism 200 and the liquid replenishment mechanism 100, the first movable component 12 can close the outlet 115, thereby closing the infusion channel 112. The second sealing component 123 has a through hole 125 on its side wall. When the atomizing mechanism 200 is combined with the liquid replenishing mechanism 100, the first movable component 12 moves relative to the housing 11, causing the through hole 125 to move with the second sealing component 123 to the outside of the connecting channel 114. The liquid matrix of the second liquid storage chamber 21 enters the second liquid storage chamber 21 from the inlet 113, the connecting channel 114, the inlet 113 end of the second sealing component 123, and the through hole 125, thereby realizing the function of injecting liquid into the second liquid storage chamber 21 and the ventilation function between the first liquid storage chamber 111 and the second liquid storage chamber 21.

[0064] In some embodiments, the first movable member 12 further includes a second sealing member 124, which is disposed outside the connecting channel 114 and is at least partially sandwiched between the closed end 123b of the second sealing member 123 and the outlet 115.

[0065] The second sealing component 124 is made of, but is not limited to, easily compressible materials such as rubber or silicone. The second sealing component 124 is sandwiched between the second sealing component 123 and the outlet 115 to provide a seal between the second sealing component 123 and the portion of the housing 11 that defines the outlet 115 when the second sealing component 123 closes the outlet 115, thereby preventing leakage of the liquid matrix.

[0066] In some embodiments, a fluid replenishment mechanism 100 is provided. The difference between this embodiment and the previous embodiment is that the first movable member 12 does not have a through hole 125. Specifically, the housing 11 defines an inlet 113, an outlet 115, and a connecting channel 114 extending from the inlet 113 to the outlet 115. The first movable member 12 closes the outlet 115. The connecting channel 114 forms a fluid delivery channel 112. The inlet 113 communicates with the first liquid storage chamber 111, and the outlet 115 can communicate with the second liquid storage chamber 21 in the atomizing mechanism 200. The first movable member 12 includes a second sealing member 123 disposed in the connecting channel 114, with a gap between the second sealing member 123 and the inner wall of the connecting channel 114. The first movable member 12 also includes a second sealing member 124 disposed outside the connecting channel 114 and at least partially sandwiched between the second sealing member 123 and the outlet 115.

[0067] In this embodiment, before the first movable member 12 moves relative to the housing 11, the second sealing member 124 provides a seal between the second blocking member 123 and the portion of the housing 11 that defines the outlet 115, preventing leakage of the liquid matrix. When the first movable member 12 moves relative to the housing 11, a gap is formed between the second sealing member 124 and the portion of the housing 11 that defines the outlet 115. The liquid matrix can then enter the second liquid storage chamber 21 through the gap between the inlet 113, the connecting channel 114 and the second blocking member 123, and the gap between the portion of the housing 11 that defines the outlet 115 and the second sealing member 124, thereby achieving smooth opening of the infusion channel 112.

[0068] Please see Figure 5 and Figure 6 , Figure 5 This is a structural schematic diagram of the atomizing device during assembly in another embodiment. Figure 6 yes Figure 5 A schematic diagram of the structure of the atomizing device when it is not assembled in the embodiment. In some embodiments, the liquid replenishment mechanism 100 further includes a first reset member 15, which can provide a restoring force after outputting a preset amount of liquid matrix to drive the first movable member 12 to move relative to the housing 11 again.

[0069] The first reset member 15 includes, but is not limited to, magnetic components or elastic components such as compression springs, torsion springs, and sheet springs. For example, the first reset member 15 is a compression spring, with one end abutting against the first movable member 12 and the other end abutting against the housing 11. The first reset member 15 provides elastic force to the first movable member 12 against the liquid matrix. Before the first movable member 12 moves relative to the housing 11, it is held in the closed infusion channel 112 position by the elastic force of the first reset member 15. When the first movable member 12 moves relative to the housing 11, the elastic force applied by the first reset member 15 to the first movable member 12 is less than the pressure applied by the liquid matrix to the first movable member 12. The first movable member 12 squeezes the first reset member 15 to move and opens the infusion channel 112, thereby allowing the liquid matrix to flow out through the infusion channel 112 and releasing the pressure in the first reservoir 111. When the pressure in the first liquid storage chamber 111 decreases to less than the elastic force of the first reset member 15 as the liquid matrix flows out, the first movable member 12 moves again relative to the housing 11 to the position of closing the infusion channel 112.

[0070] Please see Figures 1-2 , Figures 3-4 As shown, in some embodiments, the fluid replenishment mechanism 100 further includes a control element 13 that is at least partially exposed outside the housing 11, the control element 13 being operable to drive the first movable element 12 to open or close the infusion channel 112.

[0071] When the atomizing mechanism 200 is combined with the liquid replenishment mechanism 100, the first movable part 12 can be independently driven to open or close the infusion channel 112 by operating the control component 13, so as to replenish the liquid matrix into the second liquid storage chamber 21 during the user's aspiration process and meet the liquid supply requirements of the atomizing core 23.

[0072] In some embodiments, at least a portion of the first movable member 12 is disposed within the infusion channel 112, while at least a portion of the control member 13 is exposed outside the housing 11. The first movable member 12 passes through the infusion channel 112 and the first liquid storage chamber 111 and is connected to the control member 13. There is a gap between the outer wall of the first movable member 12 and the inner wall of the infusion channel 112. After the control member 13 drives the first movable member 12 to open the infusion channel 112, the liquid matrix in the first liquid storage chamber 111 can enter the infusion channel 112 through the gap between the first movable member 12 and the inner wall of the infusion channel 112.

[0073] Please continue reading. Figure 1 and Figure 2In some embodiments, the control member 13 includes a pressing member 131 connected to the first movable member 12, and the infusion replenishment mechanism 100 further includes a second reset member 133. When the pressing member 131 is pressed, it can move the first movable member 12 relative to the housing 11 to open the infusion channel 112; and when the pressing operation is released, the second reset member 133 can provide a restoring force to drive the first movable member 12 to move again relative to the housing 11 and return to the state of closing the infusion channel 112.

[0074] The second reset member 133 includes, but is not limited to, elastic elements such as compression springs, torsion springs, and spring sheets. For example, the second reset member 133 is a compression spring, with one end abutting against the first movable member 12 and the other end abutting against the housing 11. This abutment can be direct or indirect; for example, one end of the second reset member 133 abuts against the control member 13, which is connected to the first movable member 12. The second reset member 133 provides elastic force to the first movable member 12 against the liquid matrix. Before the first movable member 12 moves relative to the housing 11, it is held in the closed infusion channel 112 position by the elastic force of the second reset member 133. When the first movable member 12 moves relative to the housing 11, for example, when the pressing member 131 is pressed, the first movable member 12 compresses the second reset member 133, causing it to move and open the infusion channel 112, thereby allowing the liquid matrix to flow out through the infusion channel 112. When the press operation is released, the second reset member 133 provides a restoring force, and the first movable member 12 moves again relative to the housing 11 to the position where the infusion channel 112 is closed. It can be understood that the second reset member 133 can also be equivalent to the aforementioned first reset member 15; that is, before the first movable member 12 moves relative to the housing 11, the first movable member 12 is held in the position where the infusion channel 112 is closed by the elastic force of the second reset member 133. When the first movable member 12 moves relative to the housing 11, the elastic force applied by the second reset member 133 to the first movable member 12 is less than the pressure applied by the liquid matrix to the first movable member 12. The first movable member 12 squeezes the second reset member 133 to move and open the infusion channel 112, thereby allowing the liquid matrix to flow out through the infusion channel 112, and releasing the pressure in the first reservoir 111. When the pressure in the first reservoir 111 decreases to less than the elastic force of the second reset member 133 as the liquid matrix flows out, the first movable member 12 moves again relative to the housing 11 to the position where the infusion channel 112 is closed.

[0075] Please see Figure 7 and Figure 8 , Figure 7 This is a structural diagram of the atomizing device during assembly in another embodiment. Figure 8 yes Figure 7This is a schematic diagram of the nebulizer device when it is not assembled. In some embodiments, the control member 13 includes a second movable member 132 that is movable relative to the housing 11. The second movable member 132 includes a first magnetic member 135, and the first movable member 12 includes a second magnetic member 126 and a third reset member 134. When the second movable member 132 moves relative to the housing 11 to a first position, the magnetic force between the first magnetic member 135 and the second magnetic member 126 can drive the first movable member 12 to move relative to the housing 11, thereby opening the infusion channel 112. When the second movable member 132 moves relative to the housing 11 to a second position, the third reset member 134 can provide a restoring force to drive the first movable member 12 to move relative to the housing 11 again and return to the state of closing the infusion channel 112.

[0076] The third reset member 134 includes, but is not limited to, elastic elements such as compression springs, torsion springs, and spring sheets. For example, the third reset member 134 is a compression spring, with one end abutting against the first movable member 12 and the other end abutting against the housing 11. This abutment can be direct or indirect. The third reset member 134 provides the first movable member 12 with a force resisting the liquid matrix and a magnetic force between the first magnetic element 135 and the second magnetic element 126.

[0077] The second movable component 132 includes, but is not limited to, being able to slide, rotate, or flip relative to the housing 11. It is only required to change the distance between the first magnetic component 135 and the second magnetic component 126 during the movement process, and no specific limitation is made here.

[0078] In one specific embodiment, the first magnetic element 135 and the second magnetic element 126 repel each other. When the second movable element 132 is in the first position, the distance from the second movable element 132 to the closed position of the first movable element 12 is less than the distance from the second movable element 132 to the open position of the first movable element 12. When the second movable element 132 is in the first position, the distance between the first magnetic element 135 and the second magnetic element 126 is less than the distance between the first magnetic element 135 and the second magnetic element 126 when the second movable element 132 is in the second position. Therefore, when the second movable element 132 moves from the second position to the first position, the repulsive force between the first magnetic element 135 and the second magnetic element 126 increases.

[0079] In the initial state, the first movable member 12 is in the closed infusion channel 112 position, and the second movable member 132 is in the second position. The user can overcome the repulsive force between the first magnetic member 135 and the second magnetic member 126, and operate the second movable member 132 to move closer to the first movable member 12 to the first position, thereby increasing the repulsive force between them. When the magnetic force and the pressure of the liquid matrix on the first movable member 12 are greater than the force of the third reset member 134, the first movable member 12 can overcome the force of the third reset member 134 and move to the open position, allowing the liquid matrix in the first reservoir 111 to flow out and the pressure in the first reservoir 111 to be released. After the user releases the second movable member 132, the second movable member 132 is repelled by magnetic force and moves away from the first movable member 12 to the second position. Simultaneously, as the pressure within the first liquid storage chamber 111 gradually decreases, the force exerted on the first movable member 12 by the third reset member 134 is greater than the pressure of the liquid matrix within the first liquid storage chamber 111 and the magnetic force between the magnetic components. Therefore, the third reset member 134 can drive the first movable member 12 to move towards the closed position and maintain it in the closed position. Similarly, the third reset member 134 can also be equivalent to the aforementioned first reset member 15.

[0080] Please see Figure 2 In some embodiments, the housing 11 defines an inlet 113, an outlet 115, and a connecting channel 114 extending from the inlet 113 to the outlet 115, the connecting channel 114 forming an infusion channel 112, and the first movable member 12 closes the inlet 113 to close the infusion channel 112. The replenishing mechanism 100 also includes a seal 16 disposed at the outlet 115, the seal 16 being puncturable or removable; when the seal 16 has not been punctured or removed and the control member 13 drives the first movable member 12 to open the inlet 113, the liquid matrix flowing out of the first reservoir 111 through the inlet 113 is temporarily stored in the connecting channel 114.

[0081] The connecting channel 114 has a larger diameter in the middle than at both ends, which facilitates the temporary storage of the liquid matrix, especially in case of accidental operation of the control component 13. Furthermore, when the replenishing mechanism 100 is removed from the atomizing mechanism 200, the connecting channel 114 can also temporarily store the liquid matrix located between the connecting channel 114 and the second storage chamber 21: when the replenishing mechanism 100 is removed from the atomizing mechanism 200, the diameters at both ends of the connecting channel 114 shrink to form a physical barrier, and the expanded section in the middle forms a receiving cavity. This allows residual liquid matrix to be temporarily stored in the middle receiving cavity, preventing it from overflowing from the port of the connecting channel 114 and reducing the probability of liquid matrix leakage.
