Refill bottles and nebulizers
[0001] This application claims priority to Chinese Patent Application No. 202423183506.9, filed on December 23, 2024, entitled "Refill Bottle and Atomizing Device", the entire contents of which are incorporated herein by reference. Technical Field
[0002] This application relates to the field of electronic atomization technology, specifically to a replenishment bottle and atomization device. Background Technology
[0003] For brand new, unused nebulizers, after attaching the replenishment bottle to the nebulizer, it is usually necessary to wait 10-15 minutes to ensure that the fluid liquid nebulizing matrix in the replenishment bottle can be fully absorbed by the liquid guide in the nebulizer and complete the lubrication of the core, thus avoiding dry burning during use.
[0004] In the existing design, there is no dedicated liquid guiding path between the refill bottle and the atomizer to facilitate rapid coil lubrication. After the refill bottle is attached to the atomizer, the fluid liquid atomizing matrix in the reservoir simply flows to the atomizer's guiding components through the outlet under gravity. Furthermore, the atomizing matrix itself has a certain viscosity, resulting in a slow lubrication process and a long waiting time before use, thus reducing the user experience. Summary of the Invention
[0005] This application provides a replenishment bottle and an atomizing device, solving the technical problems of low lubrication efficiency and long waiting time before use in existing atomizing devices. The replenishment bottle of this application utilizes the volume of the atomizer inserted into the reservoir to quickly squeeze out a portion of the atomizing matrix. This portion of the atomizing matrix is pressurized to the liquid guiding channel, where fluid pressure drives a pressure-triggered conductive structure. This allows the atomizing matrix to flow rapidly to the atomizer via the liquid guiding channel and the pressure-triggered conductive structure in a branch-flow manner. Furthermore, since the atomizer itself extends at least partially into the reservoir as the main pathway for communication with the atomizing matrix, it can simultaneously adsorb the atomizing matrix, thereby significantly improving lubrication efficiency, reducing waiting time, facilitating user operation, and enhancing the user experience.
[0006] In some embodiments of this application, a replenishment bottle is provided for use in an atomizing device, the atomizing device including an atomizer, the replenishment bottle being detachably mounted to the atomizer; the replenishment bottle is provided with a reservoir for storing a liquid atomizing matrix and at least one pressure-triggered conductive structure, the replenishment bottle including a liquid guiding channel, one end of the liquid guiding channel communicating with the reservoir and the other end of the liquid guiding channel communicating with the atomizer, the pressure-triggered conductive structure being disposed within the liquid guiding channel and configured to control the opening and closing of the liquid guiding channel; when the replenishment bottle is not mounted to the atomizer, the pressure-triggered conductive structure is closed; when the replenishment bottle is mounted to the atomizer, at least a portion of the atomizer is sealed and inserted into the replenishment bottle and extends into the reservoir, so as to press a portion of the atomizing matrix into the liquid guiding channel and drive the pressure-triggered conductive structure to open, so that the atomizing matrix is ejected through the pressure-triggered conductive structure and enters the atomizer.
[0007] In some embodiments, the refill bottle includes a bottle body and an elastic seal detachably mounted on the bottle body, wherein the elastic seal defines the reservoir cavity between the elastic seal and the inner cavity of the bottle body;

[0010] When the replenishment bottle is assembled into the nebulizer, at least a portion of the nebulizer is sealed and inserted into the insertion slot, and at least a portion pierces the bottom surface of the insertion slot and extends into the liquid storage chamber.
[0011] In some embodiments, the elastic sealing body is further provided with a drainage groove, the drainage groove is arranged along the direction of gravity, and one end of the drainage groove is connected to the liquid outlet end of the liquid guiding channel, and the other end of the drainage groove is connected to the insertion groove.
[0012] In some embodiments, the refill bottle further includes a cap and a closure, the cap being detachably fitted to the bottle body, and the resilient sealing element being sealed and clamped between the bottle body and the cap;
[0013] The cover is provided with a through-hole corresponding to the position of the insertion slot, and the sealing member is fixed to the cover and closes the insertion hole;
[0014] When the replenishment bottle is assembled into the nebulizer, at least a portion of the nebulizer punctures the closure and is sealed into the insertion slot via the insertion interface.
[0015] In some embodiments, the pressure-triggered conduction structure includes a flexible wall formed on the inner wall of the liquid guiding channel and extending axially along the liquid guiding channel. The flexible wall extends from the liquid inlet end of the liquid guiding channel to the liquid outlet end of the liquid guiding channel and gradually contracts into a conical shape.
[0016] The flexible wall has an inlet at one end facing the liquid inlet of the liquid guiding channel, and a spray hole extending axially along the liquid guiding channel at the other end facing the liquid outlet of the liquid guiding channel. The diameter of the inlet is larger than the diameter of the spray hole.
[0017] The pressure-triggered conduction structure further includes at least two flexible baffles, which are disposed at the opening of the spray hole facing the liquid outlet of the liquid guiding channel, so as to automatically close the spray hole in the non-pressurized state and automatically open and connect the liquid inlet and liquid outlet of the liquid guiding channel in the pressurized state.
[0018] In some embodiments of this application, an atomizing device is provided, the atomizing device comprising an atomizer and a replenishment bottle assembled together, the atomizer being an atomizer as described in any of the above claims, and the replenishment bottle being a replenishment bottle as described in any of the above claims; the atomizing device includes a liquid guiding component, an atomizing air passage, and a heating element, the atomizing air passage being disposed on the liquid guiding component, the heating element being housed in the atomizing air passage, and the heating element being at least partially attached to the liquid guiding component; when the replenishment bottle is assembled with the atomizer, at least a portion of the liquid guiding component is sealed and inserted into the replenishment bottle and extends into the liquid storage chamber.
[0019] In some embodiments, the liquid guiding component is an integral ceramic liquid guiding component, including a main body and a plug-in portion. The atomizing air passage is disposed through the main body along the axial direction of the atomizer, and the plug-in portion is radially connected to the main body. When the replenishment bottle is assembled into the atomizer, the plug-in portion is at least partially sealed and plugged into the replenishment bottle and extends into the liquid storage chamber.
[0020] In some embodiments, the nebulizing device further includes a locking mechanism disposed between the nebulizer and the replenishment bottle to limit the replenishment bottle on the nebulizer.
[0021] In some embodiments, the atomizing device further includes an elastic drive mechanism disposed between the atomizer and the replenishment bottle, so that when the locking mechanism is unlocked, the elastic drive mechanism automatically drives the replenishment bottle to move in the extraction direction.
[0022] The replenishment bottle provided in this application is used in an atomizing device and is detachably mounted on the atomizer of the atomizing device. The replenishment bottle is provided with a liquid storage chamber for storing a liquid atomizing matrix and at least one pressure-triggered conductive structure. The replenishment bottle includes a liquid guiding channel that connects the liquid storage chamber and the atomizer. The pressure-triggered conductive structure is disposed within the liquid guiding channel and is configured to control the opening and closing of the liquid guiding channel.
[0023] When the refill bottle is not installed in the atomizer, the pressure-triggered conduction structure is closed, preventing leakage of the atomizing matrix from the reservoir through this structure and ensuring the bottle's airtightness during shelf life. Before actual use, when the user installs the refill bottle into the atomizer along the insertion direction, at least a portion of the atomizer is sealed and inserted into the bottle, extending into the reservoir. This displacement of the atomizing matrix by volume displacement forces it into the liquid channel, where its own fluid pressure activates the pressure-triggered conduction structure. This allows the matrix to be rapidly introduced into the atomizer via the liquid channel and the pressure-triggered conduction structure in a branch-like manner. Furthermore, since at least a portion of the atomizer extends into the reservoir, it can simultaneously adsorb the atomizing matrix, significantly improving the speed of matrix adsorption, increasing lubrication efficiency, reducing pre-use waiting time, facilitating user operation, and enhancing the user experience.

Specific Implementation
[0033] Please refer to Figures 1 to 4. In some embodiments of this application, a replenishment bottle 30 is provided. The replenishment bottle 30 is used in an atomizing device 1. The atomizing device 1 includes an atomizer 100, and the replenishment bottle 30 is detachably mounted on the atomizer 100.
[0034] The replenishment bottle 30 is provided with a liquid storage chamber 301 for storing atomized matrix and at least one pressure-triggered conduction structure 321 for the passage of atomized matrix. The replenishment bottle 30 includes a liquid guiding channel 322, one end of which is connected to the liquid storage chamber 301 and the other end of which is connected to the atomizer 100. The pressure-triggered conduction structure 321 is disposed in the liquid guiding channel 322 and is configured to control the opening and closing of the liquid guiding channel 322.
[0035] When the replenishment bottle 30 is not installed in the atomizer 100, the pressure-triggered conduction structure 321 is closed; when the replenishment bottle 30 is installed in the atomizer 100 along the insertion direction, at least part of the atomizer 100 is sealed and inserted into the replenishment bottle 30 and extends into the liquid storage chamber 301, so as to press part of the atomized matrix into the liquid guiding channel 322 and drive the pressure-triggered conduction structure 321 to conduct, so that this part of the atomized matrix is sprayed out through the pressure-triggered conduction structure 321 and enters the atomizer 100.
[0036] The pressure-triggered conduction structure 321 can be a flexible nozzle with an elastic valve. Such a flexible nozzle can achieve self-sealing under normal conditions by utilizing the elasticity of the elastic valve itself. When the fluid pressure of the atomizing matrix pressed into the liquid guiding channel 322 exceeds the pressure that the elastic valve can withstand, it will deform and open, so that the atomizing matrix can be ejected through the flexible nozzle and enter the atomizer 100.
[0037] The pressure-triggered conduction structure 321 can also employ a pressure-controlled check valve, such as a check valve combining a pressure sensor and a corresponding control structure. In a non-pressurized state or when the fluid pressure of the atomized matrix detected by the pressure sensor is less than the preset minimum pressure threshold for check valve activation, the check valve self-seales. When the pressure sensor detects that the fluid pressure of the atomized matrix pressed into the liquid guiding channel 322 reaches the preset minimum pressure threshold for check valve activation, the corresponding control structure controls the valve core of the check valve to actuate and activate, allowing the atomized matrix to be ejected through the check valve and enter the atomizer 100.
[0038] The pressure-controlled check valve can also be a spring-loaded check valve, which has a spring inside that acts on the valve core. Under non-pressurized conditions or when the fluid pressure of the atomizing matrix is less than the spring's own force, the valve core closes under the spring's own force, achieving self-sealing. When the fluid pressure of the atomizing matrix pressed into the liquid channel 322 exceeds the spring's own force, the valve core is pushed open and conducts, allowing the atomizing matrix to be ejected through the spring-loaded check valve and enter the atomizer 100.
[0039] Pressure-controlled check valves can also be pilot-operated check valves, which consist of a main valve and a pilot valve. Under non-pressurized conditions or when the fluid pressure of the atomizing matrix is less than the closing pressure of the pilot valve, the pilot valve closes, the pressure in the upper chamber of the main valve recovers, and the main valve closes under spring force or other reset force to achieve self-sealing. When the fluid pressure of the atomizing matrix reaches the opening pressure of the pilot valve, the pilot valve opens first, reducing the pressure in the upper chamber of the main valve, thus creating a pressure difference between the upper and lower chambers of the main valve. This pressure difference pushes the main valve open and conducts, allowing the atomizing matrix to be ejected through the pilot-operated check valve and enter the atomizer 100.
[0040] Pressure-controlled check valves can also be pressure-sensitive check valves. These valves employ special materials or structural designs to make their valve core or seat sensitive to pressure changes. Under non-pressurized conditions or when the fluid pressure of the atomizing matrix is less than its response pressure value, the valve core or seat remains unchanged, achieving self-sealing. When the fluid pressure of the atomizing matrix reaches its response pressure value, the physical properties of the valve core or seat change, achieving conduction, allowing the atomizing matrix to be ejected through the pressure-sensitive check valve and enter the atomizer 100.
[0041] The replenishment bottle 30 provided in this application connects the liquid storage chamber 301 and the atomizer 100 through the liquid guiding channel 322, and controls the opening and closing of the liquid guiding channel 322 through the pressure-triggered conduction structure 321, so that at least part of the atomizing matrix stored in the liquid storage chamber 301 can be pressurized to the pressure-triggered conduction structure 321 through the liquid guiding channel 322, and this part of the atomizing matrix can be sprayed out through the pressure-triggered conduction structure 321 and enter the atomizer 100.
[0042] For the new atomizing device 1, during shelf life or before use, the replenishment bottle 30 is not installed in the atomizer 100. At this time, the pressure-triggered conductive structure 321 is not affected by the fluid pressure of the atomizing matrix and achieves self-sealing to close the liquid channel 322. This can prevent the atomizing matrix in the liquid storage chamber 301 from leaking out through the pressure-triggered conductive structure 321, thus ensuring the sealing of the replenishment bottle 30 during shelf life.
[0043] Before actual use, when the user assembles the replenishment bottle 30 into the atomizer 100 along the insertion direction, at least part of the atomizer 100 is sealed and inserted into the replenishment bottle 30 and extends into the liquid storage chamber 301. This displaces part of the atomizing matrix in the liquid storage chamber 301 by occupying volume, and presses this part of the atomizing matrix into the liquid guiding channel 322. The fluid pressure of the atomizing matrix itself can drive the pressure-triggered conductive structure 321 to conduct, so that this part of the atomizing matrix can flow quickly to the atomizer 100 through the liquid guiding channel 322 and the pressure-triggered conductive structure 321 in a branch-conducting manner. Furthermore, since at least a portion of the atomizer 100 extends into the liquid storage chamber 301 as the main path for communication with the atomizing matrix, it can simultaneously adsorb the atomizing matrix in the liquid storage chamber 301 in a manner that combines the main path with the branch path. This significantly improves the speed at which the atomizer 100 adsorbs the atomizing matrix, increases the lubrication efficiency, reduces the waiting time before use, makes it more convenient for users, and enhances the user experience.
[0044] In other embodiments, the replenishment bottle 30 may also be provided with two or more liquid guiding channels 322 simultaneously. Each liquid guiding channel 322 is provided with a pressure-triggered conduction structure 321 to control the opening or closing of the liquid guiding channel 322. The distribution position of each pressure-triggered conduction structure 321 can be set according to the specific shape, size, position and other characteristics of the atomizer 100, ensuring that each pressure-triggered conduction structure 321 can efficiently and quickly spray the atomized matrix and deliver it to the atomizer 100. After the replenishment bottle 30 is assembled onto the atomizer 100 along the insertion direction, the portion of the atomized matrix displaced by the part of the atomizer 100 inserted into the liquid storage chamber 301 can be pressed into the corresponding pressure-triggered conduction structure 321 through each liquid guiding channel 322 and sprayed out. Thus, by using multiple pressure-triggered conduction structures 321 at the same time and in multiple different positions to simultaneously lubricate the atomizer 100, the lubrication efficiency can be further improved and the waiting time before use can be further reduced.
[0045] Please refer to Figure 1. In some embodiments of this application, an atomizing device 1 is provided. The atomizing device 1 includes an atomizer 100 and a replenishment bottle 30 assembled together. The atomizer 100 is the atomizer 100 as described above, and the replenishment bottle 30 is the replenishment bottle 30 as described above.
[0046] The atomizer 100 is provided with a liquid guide 13 for adsorbing the atomized matrix. After the replenishment bottle 30 is assembled onto the atomizer 100 along the insertion direction, at least part of the liquid guide 13 is sealed and inserted into the replenishment bottle 30 and extends into the liquid storage chamber 301, so as to press part of the atomized matrix into the liquid guide channel 322 and drive the pressure-triggered conduction structure 321 to conduct, so that this part of the atomized matrix is sprayed out through the pressure-triggered conduction structure 321 and enters the atomizer 100, thereby achieving rapid lubrication of the core.
[0047] For a brand-new replenishment bottle 30, the reservoir 301 is pre-filled with atomizing matrix before leaving the factory. Preferably, the reservoir 301 is completely filled with atomizing matrix, leaving no unfilled space. Alternatively, the reservoir 301 may have only a small amount of unfilled space. The volume of the unfilled space in the reservoir 301 should be smaller than the volume of the portion of the liquid guide 13 of the atomizer 100 that extends into the reservoir 301. This ensures that after the replenishment bottle 30 is assembled onto the atomizer 100, the portion of the liquid guide 13 extending into the reservoir 301 can displace a sufficient amount of atomizing matrix through volume occupation, and this displaced atomizing matrix is then forced through the liquid guide channel 322 into the pressure-triggered conductive structure 321 and ejected.
[0048] When the reservoir 301 is filled with atomizing matrix, the volume of the portion of the liquid guide 13 extending into the reservoir 301 is actually equal to the volume of the displaced atomizing matrix. In actual manufacturing, the volume of the portion of the liquid guide 13 extending into the reservoir 301 can be appropriately designed according to the filling amount of atomizing matrix in the reservoir 301 and the amount of atomizing matrix that the liquid guide 13 needs to adsorb to complete the wick lubrication, so as to ensure that after the replenishment bottle 30 is assembled on the atomizer 100, rapid wick lubrication can be achieved through the replenishment bottle 30 of this application.
[0049] When the replenishment bottle 30 is assembled into the atomizer 100, the liquid guide 13 replaces part of the atomizing matrix in the liquid storage chamber 301 by occupying volume, achieving rapid lubrication of the core. During subsequent use, since the insertion volume of the liquid guide 13 remains unchanged, and the liquid guide 13 continuously and extensively adsorbs the atomizing matrix through the portion inserted into the liquid storage chamber 301, it is difficult for the liquid guide 13 to replace the atomizing matrix by occupying volume through the liquid guide channel 322 and the pressure-triggered conductive structure 321. This avoids leakage of the atomizing matrix in the liquid storage chamber 301 through the liquid guide channel 322 and the pressure-triggered conductive structure 321 during subsequent use.
[0050] In one specific embodiment, the volume of the portion of the liquid guide 13 extending into the liquid storage chamber 301 is designed to be 0.6 ml. When the liquid storage chamber 301 is filled with atomizing matrix, after the replenishment bottle 30 is assembled onto the atomizer 100 along the insertion direction, the portion of the liquid guide 13 extending into the liquid storage chamber 301 can squeeze out 0.6 ml of atomizing matrix in equal amounts, and this portion of atomizing matrix is pressed into the pressure-triggered conductive structure 321 through the liquid guide channel 322 and sprayed out, thereby achieving rapid lubrication of the core.
[0051] In some other embodiments, the volume of the portion of the liquid guide 13 that extends into the liquid storage cavity 301 can be set according to the actual situation of the atomizing device 1. This application does not limit this, as long as it can meet the lubrication requirements.
[0052] Referring to Figure 4, in some embodiments, in the replenishment bottle 30 of this application, the liquid guiding channel 322 is located above the liquid guiding member 13 in the direction of gravity. The inlet end of the liquid guiding channel 322 is connected to the liquid storage chamber 301, and the outlet end of the liquid guiding channel 322 is connected to the liquid guiding member 13. The direction of gravity is represented in Figure 4 as the vertical direction and the axial direction of the atomizer 100.
[0053] The pressure-triggered conductive structure 321 is located in the liquid guiding channel 322. The sprayed atomized matrix automatically flows to the liquid guiding component 13 through the liquid outlet end of the liquid guiding channel 322 under the action of gravity.
[0054] In this application, the liquid guiding channel 322 is located in the upper part of the liquid guiding component 13 in the direction of gravity, and the pressure-triggered conductive structure 321 is located in the liquid guiding channel 322. The liquid guiding channel 322 actually plays the role of drainage. On the one hand, it can guide the atomized matrix in the liquid storage chamber 301 to the pressure-triggered conductive structure 321. On the other hand, it can also guide the atomized matrix sprayed through the pressure-triggered conductive structure 321 to the liquid guiding component 13 in a directional manner, preventing the atomized matrix from splashing around and causing leakage.
[0055] In addition, after the liquid guide 13 is inserted, the internal pressure of the liquid storage chamber 301 increases and squeezes part of the atomizing matrix into the liquid guide channel 322. This also facilitates the atomizing matrix to be ejected at high speed from the pressure-triggered conductive structure 321 at a greater pressure, and to flow automatically and quickly to the liquid guide 13 under the action of gravity, resulting in high lubrication efficiency and good effect.
[0056] Referring to Figure 4, in some embodiments, the pressure-triggered conductive structure 321 is preferably located near the inlet end of the liquid guiding channel 322 to reserve sufficient spray distance for the atomized matrix to be ejected, which is conducive to the accumulation and diversion of the atomized matrix to the liquid guiding component 13 at the outlet end of the liquid guiding channel 322.
[0057] Referring to Figure 4, in some embodiments, the liquid guiding channel 322 is preferably arranged along the insertion direction of the replenishment bottle 30, and the liquid guiding channel 322 is located above the gravity direction of the liquid guiding component 13. In this way, the path length of the atomized matrix sprayed through the pressure-triggered conductive structure 321 to the liquid guiding component 13 can be minimized, and the atomized matrix discharged through the liquid outlet end of the liquid guiding channel 322 can automatically flow onto the liquid guiding component 13 under the action of gravity, thereby improving the lubrication efficiency.
[0058] Referring to Figures 2 to 4, in some embodiments, the refill bottle 30 includes a bottle body 31 and an elastic sealing body 32 detachably mounted on the bottle body 31. The elastic sealing body 32 and the inner cavity of the bottle body 31 define a liquid storage cavity 301. A liquid guiding channel 322 is provided on the elastic sealing body 32 along the insertion direction of the refill bottle 30.
[0059] The elastic seal 32 is preferably made of silicone material, which gives the elastic seal 32 itself good elasticity, ensures the sealing of the liquid storage cavity 301 defined between the elastic seal 32 and the inner cavity of the bottle 31, and prevents the atomized matrix from leaking out through the gap between the elastic seal 32 and the bottle 31.
[0060] The liquid guiding channel 322 and the pressure-triggered conductive structure 321 are both integrally formed on the elastic sealing body 32, which makes the pressure-triggered conductive structure 321 also have good elasticity, ensuring the self-sealing effect of the pressure-triggered conductive structure 321 under normal conditions, avoiding leakage of the pressure-triggered conductive structure 321 when not in use, and also ensuring that when the replenishment bottle 30 is assembled in the insertion direction into the atomizer 100, the part of the atomizing matrix squeezed and displaced by the liquid guiding component 13 can be opened by the pressure-triggered conductive structure 321 and sprayed out under pressure.
[0061] In some embodiments, the bottle body 31 is made of plastic and has a barrel-shaped structure with an inner cavity, while the elastic seal 32 is made of silicone and has a plate-shaped structure that fits the opening end of the inner cavity of the bottle body 31. The elastic seal 32 has opposing inner and outer wall surfaces, wherein the inner wall surface faces the inner cavity of the bottle body 31 and defines the liquid storage cavity 301 therewith, and the outer wall surface faces the liquid guide 13.
[0062] The inlet end of the liquid guiding channel 322 penetrates the inner wall of the elastic seal 32, so that the atomizing matrix in the liquid storage chamber 301 can flow directly into the liquid guiding channel 322 through the inlet end of the liquid guiding channel 322.
[0063] Please refer to Figures 2 to 4. In some embodiments, the elastic sealing body 32 is also provided with a plug groove 323. The plug groove 323 is arranged along the plugging direction of the replenishment bottle 30, and the plug groove 323 is located at the lower part of the gravity direction of the liquid guiding channel 322.
[0064] When the user assembles the replenishment bottle 30 into the atomizer 100 along the insertion direction, the liquid guide 13 is at least partially sealed and inserted into the insertion groove 323, at least partially pierces the bottom surface of the insertion groove 323 and extends into the liquid storage chamber 301.
[0065] The insertion groove 323 can guide the replenishment bottle 30 to be assembled into the atomizer 100 along the insertion direction, and guide at least a portion of the liquid guide 13 to be inserted into the liquid storage chamber 301. The inner wall of the insertion groove 323 can seal and wrap the outer wall surface of the corresponding portion of the liquid guide 13 in contact with it to form a seal, so as to ensure that after the replenishment bottle 30 is assembled into the atomizer 100, the atomizing matrix in the liquid storage chamber 301 will not leak out through the gap between the insertion groove 323 and the liquid guide 13, thus playing a sealing and protective role.
[0066] The insertion groove 323 is recessed on one side of the outer wall of the elastic sealing body 32, and the bottom surface of the insertion groove 323 forms a sealing membrane 3231 that seals the liquid storage cavity 301. During the assembly process of the replenishment bottle 30, the end of the liquid guide 13 that extends into the liquid storage cavity 301 can pierce the sealing membrane 3231.
[0067] The bottom surface of the insertion groove 323 is preferably located close to the inner wall surface of the elastic seal 32 to reduce the thickness of the formed sealing film 3231, making it easier for the liquid guide 13 to puncture the replenishment bottle 30 during assembly, thereby reducing assembly resistance and the degree of deformation of the elastic seal 32.
[0068] Referring to Figure 2, in some embodiments, the opening of the insertion groove 323 on the outer wall of the elastic sealing body 32 is configured as an outwardly expanding flared structure, so that the opening end of the insertion groove 323 forms an inwardly inclined extending guide surface 3232, so as to guide the insertion of the liquid guiding component 13 through the guide surface 3232, which facilitates the assembly of the replenishment bottle 30 and the atomizer 100 and improves the assembly efficiency of the atomizing device 1.
[0069] Please refer to Figure 2. In some embodiments, at least one circumferentially surrounding sealing ring 3233 is provided on the inner wall of the insertion groove 323. After the replenishment bottle 30 is assembled on the atomizer 100, the sealing ring 3233 seals the gap between the insertion groove 323 and the liquid guide 13, further improving the sealing effect between the insertion groove 323 and the liquid guide 13 and preventing leakage.
[0070] In some embodiments, the elastic sealing body 32 is further provided with a drainage groove 324, which is arranged along the direction of gravity, and the upper end of the drainage groove 324 is connected to the liquid outlet end of the liquid guiding channel 322, and the lower end of the drainage groove 324 is connected to the insertion groove 323.
[0071] This application connects the outlet end of the liquid guiding channel 322 to the insertion groove 323 through the diversion groove 324, so that the atomized matrix sprayed through the pressure-triggered conductive structure 321 can automatically flow to the liquid guiding component 13 through the diversion groove 324 under the guidance of the outlet end of the liquid guiding channel 322 and under the action of gravity, which plays a diversion role and facilitates the rapid adsorption of the atomized matrix onto the liquid guiding component 13 to achieve core lubrication.
[0072] The liquid outlet of the liquid channel 322 preferably penetrates the outer wall of the elastic seal 32 along the insertion direction of the replenishment bottle 30, and the drainage groove 324 is formed vertically inward from the outer wall of the elastic seal 32. This reduces the manufacturing difficulty of the elastic seal 32, facilitates demolding, and saves production costs.
[0073] Please refer to Figures 2 and 4. In some embodiments, the refill bottle 30 of this application further includes a cap 33 and a closure 34. The cap 33 is detachably assembled to the bottle body 31, and the elastic sealing body 32 is sealed and clamped between the bottle body 31 and the cap 33.
[0074] The cover 33 has a through-hole interface 331 at the position corresponding to the insertion slot 323, and the sealing member 34 is fixed to the cover 33 and closes the interface 331.
[0075] When the replenishment bottle 30 is assembled into the nebulizer 100, the end of the liquid guide 13 inserted into the liquid storage chamber 301 will pierce the sealing member 34 and be sealed and inserted into the insertion slot 323 through the insertion interface 331.
[0076] The cap 33, in conjunction with the bottle body 31, confines the elastic seal 32 within the replenishment bottle 30, ensuring the airtightness of the storage cavity 301 defined between the elastic seal 32 and the inner cavity of the bottle body 31, and preventing leakage. The cap 33 also provides protection for the elastic seal 32, preventing it from loosening or breaking due to external forces during transportation or shelf life. Furthermore, the combination of the cap 33 and the bottle body 31, which confines the elastic seal 32, prevents significant deformation of the elastic seal 32 caused by external forces during the insertion of the liquid guide 13 into the insertion groove 323 and puncture of the sealing film 3231, thus avoiding leakage.
[0077] This application uses the sealing element 34 to seal the insertion interface 331 on the cover 33, which can prevent external impurities from entering the insertion slot 323 through the insertion interface 331 during shelf life or before use, thus playing a role in isolation and protection.
[0078] In some embodiments, the sealing element 34 is an aluminum film, which is fixed to the outer wall of the cover 33 by adhesive. The aluminum film itself has a certain strength, which can prevent it from being easily punctured by external objects during non-assembly processes, but will not affect the normal puncture of the liquid guiding element 13 during assembly. In addition, the liquid guiding element 13 only punctures an opening in the aluminum film rather than detaching the entire aluminum film, and the part of the aluminum film sealing the periphery of the insertion interface 331 can still play a certain sealing role. Therefore, even if an abnormality occurs during use where the liquid guiding element 13 excessively absorbs the atomized matrix and drips, the dripping droplets will be blocked by the aluminum film, avoiding the problem of leakage.
[0079] In some other embodiments, the sealing member 34 may also be a silicone film, a plastic film, etc. This application does not limit this, as long as it can play an isolation and protection role and does not affect the normal piercing and insertion of the liquid guiding member 13.
[0080] Please refer to Figures 4 and 6. In some embodiments, a reinforcing member 35 is provided on the elastic seal. The reinforcing member 35 is at least partially embedded inside the elastic seal body 32 and at least partially exposed outside the elastic seal body 32. After the bottle body 31, the elastic seal body 32, and the cap body 33 are assembled to form the replenishment bottle 30, the cap body 33 at least partially abuts against the portion of the reinforcing member 35 exposed outside the elastic seal body 32.
[0081] This application reinforces the structure of the elastic sealing body 32 with the reinforcing member 35, and the exposed part of the reinforcing member 35 abuts against the cover 33 to prevent the pressure of the cover 33 from damaging the elastic sealing body 32. This ensures that the overall structure of the elastic sealing body 32 will not undergo significant deformation during the assembly of the replenishment bottle 30 into the atomizer 100, thus ensuring the sealing effect.
[0082] The reinforcing member 35 is preferably made of stainless steel.
[0083] Please refer to 6. In some embodiments, the pressure-triggered conductive structure 321 of the replenishment bottle 30 of this application includes a flexible wall 3211 formed on the inner wall of the liquid guiding channel 322 and extending axially along the liquid guiding channel 322. The flexible wall 3211 extends from the liquid inlet end of the liquid guiding channel 322 to the liquid outlet end of the liquid guiding channel 322 and gradually contracts into a conical shape.
[0084] The flexible wall 3211 has an inlet 3212 at one end facing the liquid inlet end of the liquid guiding channel 322, and a spray hole 3213 extending axially along the liquid guiding channel 322 at the other end facing the liquid outlet end of the flexible wall 3211. The diameter of the inlet 3212 is larger than the diameter of the spray hole 3213.
[0085] The pressure-triggered conductive structure 321 of the replenishment bottle 30 of this application also includes at least two flexible baffles 3214. The at least two flexible baffles 3214 are disposed at the opening of the spray hole 3213 facing the liquid outlet end of the liquid guiding channel 322, so as to automatically close the spray hole 3213 in the non-pressurized state and automatically open and connect the liquid inlet end and the liquid outlet end of the liquid guiding channel 322 in the pressurized state.
[0086] The pressure-triggered conductive structure 321 of the replenishment bottle 30 of this application has a conical flexible wall 3211 and at least two flexible baffles 3214, which makes the diameter of the inlet 3212 of the flexible wall 3211 facing the opening end of the liquid guiding channel 322 significantly larger than the diameter of the spray hole 3213 of the flexible wall 3211 facing the liquid guiding channel 322. This conical flexible wall 3211 structure design is beneficial to the atomizing matrix entering through the inlet 3212 under the compression of the liquid guiding component 13 during the assembly of the replenishment bottle 30 into the atomizer 100, which is then sprayed out at high speed through the spray hole 3213, significantly improving the spray speed of the atomizing matrix and forming an effect similar to a Tesla valve, which can further improve the lubrication efficiency.
[0087] The flexible baffles 3214 are arranged in a centrally symmetrical structure. Adjacent flexible baffles 3214 can be configured to have end-face contact or allow for minute gaps, so that the flexible baffles 3214 together form a structure similar to an elastic valve. Under normal conditions, the flexible baffles 3214 achieve self-sealing through their own elasticity, preventing the atomized matrix from being exposed through the pressure-triggered conductive structure 321. During the assembly of the replenishment bottle 30 into the nebulizer 100, the liquid guide 13 presses the atomized matrix into the pressure-triggered conductive structure 321. The flexible baffles 3214 open under the fluid pressure of the atomized matrix, allowing the atomized matrix to be ejected through the pressure-triggered conductive structure 321.
[0088] Because the flexible wall 3211 adopts a conical structure design and the spray hole 3213 itself extends along the axial direction of the liquid guiding channel 322 and has a certain axial depth, the flexible baffle 3214 blocks the liquid outlet end of the spray hole 3213, making the spray hole 3213 form a blind hole-like structure. This ensures that the flexible baffle 3214 of the pressure-triggered conductive structure 321 will only open when it is subjected to an external force from the liquid inlet end of the liquid guiding channel 322. When it is not subjected to an external force, it can ensure the closed state of the pressure-triggered conductive structure 321, which significantly reduces the risk of leakage of the pressure-triggered conductive structure 321.
[0089] This application achieves the pressure-triggered conduction function of the flexible nozzle by automatically closing the spray hole 3213 under normal conditions through at least two flexible baffles 3214, so that the pressure-triggered conduction structure 321 constitutes a flexible nozzle with an elastic diaphragm. While realizing the pressure-triggered conduction function of the flexible nozzle, it eliminates the need for complex pressure sensors, control mechanisms, check valves and other structures, which significantly reduces the production cost of the replenishment bottle 30.
[0090] In some embodiments, the inner diameter of the spray hole 3213 of the pressure-triggered conductive structure 321 is preferably set to 0.3 mm. The axial depth of the spray hole 3213 is preferably set to 0.2 mm to 0.5 mm, such as 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, etc. The diameter of the inlet 3212 of the pressure-triggered conductive structure 321 is preferably set to 1.0 mm to 1.5 mm, such as 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, etc. The straight-line distance between the inlet 3212 and the inlet end of the spray hole 3213 is preferably set to 0.4 mm to 0.8 mm, such as 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, etc.
[0091] Please refer to Figures 3 and 4. The atomizing device 1 of this application also includes an atomizing air passage 1311 and a heating element 14. The atomizing air passage 1311 is disposed on the liquid guiding member 13 as described above. The heating element 14 is housed in the atomizing air passage 1311 and the heating element 14 is at least partially attached to the liquid guiding member 13.
[0092] In actual use, the liquid guide 13 transfers the adsorbed atomized matrix to the surface of the atomizing air passage 1311. The heating element 14, driven by electricity, performs work to heat the atomized matrix transferred by the liquid guide 13, atomizing it and generating an aerosol. The generated aerosol mixes with the airflow entering from outside the atomizer 100 within the atomizing air passage 1311 to form atomized gas that can be inhaled by the user.
[0093] In the following embodiments, the atomizing device 1 is described using an electronic cigarette as an example, and the atomizing matrix is described using liquid e-liquid as an example. However, the atomizing device 1 of this application is not limited to electronic cigarettes, and the atomizing matrix is not limited to liquid e-liquid.
[0094] Please refer to Figures 4 and 7. In some embodiments, the liquid guiding component 13 of the atomizing device 1 of this application is an integral ceramic liquid guiding component, including a main body 131 and a plug-in portion 132. The atomizing air passage 1311 is disposed through the main body 131 along the axial direction of the atomizer 100, and the plug-in portion 132 is radially connected to the main body 131.
[0095] When the replenishment bottle 30 is assembled into the atomizer 100, the insertion part 132 of the liquid guide 13 is at least partially sealed and inserted into the replenishment bottle 30 and extends into the liquid storage chamber 301, so as to achieve rapid lubrication of the core.
[0096] In some embodiments, the main body 131 is configured as a cylindrical structure, the atomizing air passage 1311 extends through the upper and lower end faces of the main body 131 along the axial direction of the atomizer 100, and the insertion part 132 is configured as a strip structure that matches the insertion groove 323 on the elastic sealing body 32.
[0097] Compared to fiber cotton liquid guides, ceramic liquid guides have higher structural strength. They can use their strength advantage to easily pierce the sealing part 34 and sealing film 3231 on the replenishment bottle 30 and insert into the liquid storage chamber 301. This improves the reliability of the replenishment bottle 30 being assembled into the atomizer 100 and realizing the liquid circuit connection between the liquid storage chamber 301 and the liquid guide 13.
[0098] Moreover, ceramic liquid guides have a better liquid-locking effect than fiber cotton liquid guides, which can minimize the excessive adsorption of atomizing matrix by the liquid guide 13 and prevent leakage caused by oversaturation of the liquid guide 13.
[0099] In addition, ceramic liquid guiding components have higher heat resistance and better chemical stability than fiber cotton liquid guiding components, are less prone to clogging, and have better atomization effect on atomizing matrix, thus improving the user experience.
[0100] Referring to Figure 7, in some embodiments, the end of the plug portion 132 inserted into the liquid storage cavity 301 is configured as a wedge-shaped structure, so that the end of the plug portion 132 has a beveled surface 1321 similar to a blade. During the process of assembling the replenishment bottle 30 into the atomizer 100, the beveled surface 1321 at the end of the plug portion 132 breaks through the sealing film 3231 formed by the sealing member 34 and the bottom surface of the plug groove, thereby reducing assembly resistance and improving the assembly efficiency of the replenishment bottle 30. At the same time, it can also significantly reduce the deformation of the elastic sealing body 32, ensuring the sealing effect of the replenishment bottle 30.
[0101] Please refer to Figures 1 and 3. The nebulizer 100 includes an atomizing device 10 and a power supply device 20, with the atomizing device 10 detachably connected to the power supply device 20. The atomizing device 10 includes a first housing 11 and a mounting base 12 housed in and engaged with the first housing 11. A mouthpiece 111 is provided near the mouth end of the first housing 11, and an atomizing air guide tube 112 extending inward from the mouthpiece 111 is provided inside the first housing 11. An installation cavity 113 is also provided on the first housing 11, and a replenishment bottle 30 is assembled in the installation cavity 113 along the insertion direction.
[0102] The mounting base 12 is provided with an atomizing chamber 121 that is connected to the atomizing air guide tube 112. One side of the atomizing chamber 121 is connected to the mounting cavity 113 and has a positioning groove 1211. The bottom of the atomizing chamber 121 penetrates the mounting base 12 for external gas to enter the atomizing chamber 121.
[0103] The main body 131 of the liquid guide 13 is fixed in the atomizing chamber 121 along the axial direction of the atomizer 100, and the atomizing air passage 1311 communicates with the atomizing chamber 121. The insertion part 132 of the liquid guide 13 extends radially into the mounting cavity 113 through the positioning slot 1211.
[0104] Referring to Figure 4, the heating element 14 includes a heating mesh 141 and positive and negative leads 142. The heating mesh 141 is housed in the atomizing air passage 1311 of the main body 131, and the heating mesh 141 is at least partially attached to the inner wall surface of the main body 131. The positive and negative leads 142 are electrically connected to the heating mesh 141 and the power supply device 20.
[0105] Please refer to Figures 1 and 3. The power supply device 20 includes a second housing 21, a support body 22 housed in the second housing 21 and defining the equipment compartment 23 therewith, a battery 24 fixed to the support body 22 and housed in the equipment compartment 23, and a control board 25.
[0106] When the atomizing device 10 is connected to the power supply device 20, a sealed air intake chamber 40 is formed between the two. The second housing 21 is provided with an air intake hole 211 for outside air to enter the air intake chamber 40. The bottom of the atomizing chamber 121 is connected to the air intake chamber 40. The positive and negative terminals 142 of the heating element 14 are electrically connected to the battery 24 and the control board 25.
[0107] In actual use, the liquid guide 13 continuously adsorbs the atomizing matrix in the liquid storage chamber 301 through the insertion part 132 inserted into the liquid storage chamber 301, and transmits it to the heating element 14 in the atomizing air passage 1311 via the main body 131. The atomizer 100 supplies power to the heating element 14 through the battery 24 and controls the operation of the heating element 14 through the control module on the control board 25. When the user inhales through the mouthpiece 111, the air pressure in the atomizing device 1 decreases, and outside air enters the air intake chamber 40 through the air inlet 211 and enters the atomizing chamber 121 through the opening at the bottom of the mounting base 12 to form an airflow. The heating element 14 performs work and generates heat under the power of the battery 24 to heat the atomizing matrix transmitted by the liquid guide 13 to atomization and generate an aerosol. The generated aerosol mixes with the incoming airflow in the atomizing air passage 1311 to form atomized gas. The atomized gas is discharged through the mouthpiece 111 under the guidance of the atomizing air guide tube 112 for the user to inhale.
[0108] Please refer to Figure 3. In some embodiments, the atomizing device 10 and the power supply device 20 are detachably connected by magnetic attraction.
[0109] At least two sets of magnetic attraction components are provided between the bottom of the mounting base 12 and the top of the bracket 22 to achieve a detachable connection between the atomizing device 10 and the power supply device 20 through at least two sets of magnetic attraction components.
[0110] Each magnetic assembly includes a first magnetic body 15 fixed to the bottom of the mounting base 12 and a second magnetic body 26 fixed to the top of the bracket 22. After the atomizing device 10 is connected to the power supply device 20, the first magnetic body 15 and the second magnetic body 26 are fixedly connected by magnetic attraction, thereby limiting the atomizing device 10 to the power supply device 20.
[0111] In some other embodiments, the atomizing device 10 and the power supply device 20 can also be detachably connected by a snap-fit method, or they can be detachably connected by both magnetic fixation and snap-fit method. This application does not limit this, as long as it can ensure that the atomizing device 10 is stably connected to the power supply device 20 and ensure that the atomizing device 1 operates normally.
[0112] Please refer to Figures 3 and 5. In some embodiments, the atomizing device 1 further includes a locking mechanism, which is located between the atomizer 100 and the replenishment bottle 30 to limit the replenishment bottle 30 on the atomizer 100.
[0113] The atomizing device 1 of this application, through the locking mechanism, can reliably limit the replenishment bottle 30 on the atomizer 100 during use, ensuring continuous liquid supply to the liquid guide 13 in the atomizing device 10, and also preventing the atomizing matrix from leaking out through the gap between the liquid guide 13 and the insertion groove 323 due to problems such as the replenishment bottle 30 becoming loose or falling out.
[0114] The locking mechanism includes a locking member 16, a first elastic member 17, and a locking groove 311. The locking member 16 has a locking portion 161, which engages with the locking groove 311. The locking member 16 and the locking groove 311 are respectively disposed on the nebulizer 100 and the replenishment bottle 30. The locking member 16 is connected to the first elastic member 17 so that it moves to a reset position or swings to a reset position under the elastic force of the first elastic member 17, thereby controlling the locking portion 161 to engage with the locking groove 311 in its normal state and limiting the replenishment bottle 30 in the insertion slot 323 of the nebulizer 100.
[0115] When disassembling the replenishment bottle 30, simply apply external force to overcome the elastic force of the first elastic member 17, drive the locking member 16 to move or swing in the opposite direction, thereby controlling the locking part 161 to disengage from the locking groove 311, and the replenishment bottle 30 can be pulled out of the insertion groove 323 in the insertion direction.
[0116] Please refer to Figures 3 and 5. In one specific embodiment, the locking member 16 is hingedly connected to the upper part of the first housing 11. One end of the locking member 16 has a locking part 161, the middle part has a hinge hole 162, and the other end has a pressing part 163. A pin 164 is inserted through the hinge hole 162, and the locking member 16 is movably connected to the first housing 11 through the pin 164. The first elastic member 17 is preferably a helical spring, arranged along the direction of gravity. The lower end of the first elastic member 17 elastically abuts against the first housing 11, and the upper end of the first elastic member 17 elastically abuts against the pressing part 163, so that under normal conditions, the locking member 16 elastically drives the locking member 16 to swing around the pin 164 to the reset position, and drives the locking part 161 to extend downward into the insertion groove 323 and the pressing part 163 to extend upward out of the first housing 11.
[0117] A locking groove 311 is provided on the outer wall of the bottle body 31 of the replenishment bottle 30. After the replenishment bottle 30 is assembled into the insertion groove 323 of the nebulizer 100 along the insertion direction, the locking groove 311 engages with the locking part 161 to limit the replenishment bottle 30 on the nebulizer 10 through the locking mechanism. When disassembling the replenishment bottle 30, the user only needs to press down on the pressing part 163 to overcome the elastic force of the first elastic member 17 and drive the locking member 16 to swing until the locking part 161 moves upward to disengage from the locking groove 311, and then the replenishment bottle 30 can be pulled out of the insertion groove 323.
[0118] In some other embodiments, the locking mechanism may also be configured as a structure in which an elastic positioning bead engages with a positioning groove, or it may be configured as a structure in which an elastic buckle engages with a slot. This application does not limit this, as long as it can reliably limit the replenishment bottle 30 on the nebulizer 100 during use without affecting the normal disassembly and assembly of the replenishment bottle 30.
[0119] In some embodiments, the atomizing device 1 of this application further includes an elastic drive mechanism, which is disposed between the atomizer 100 and the replenishment bottle 30, so that when the locking mechanism is unlocked, the elastic drive mechanism automatically drives the replenishment bottle 30 to move in the extraction direction.
[0120] The atomizing device 1 of this application, through its elastic drive mechanism, can automatically push the replenishment bottle 30 out in the extraction direction during disassembly, thereby improving the disassembly efficiency of the replenishment bottle 30.
[0121] Referring to Figure 7, in one specific embodiment, the elastic drive mechanism includes a movable push rod 18 and a second elastic element 19. The movable push rod 18 is preferably rod-shaped, with a radially protruding limiting portion 181 in the middle. The movable push rod 18 is movably connected to the mounting base 12 of the atomizing device 10 along the insertion direction of the replenishment bottle 30, and at least partially extends into the mounting cavity 113 at one end of the movable push rod 18 facing the replenishment bottle 30. The limiting portion 181 in the middle of the movable push rod 18 stops against the mounting base 12 to prevent the movable push rod 18 from dislodging.
[0122] The second elastic element 19 is preferably a helical spring, which is axially sleeved on the movable push rod 18. The end of the second elastic element 19 facing away from the replenishment bottle 30 elastically abuts against the inner wall of the mounting base 12 or the first housing 11, and the end of the second elastic element 19 facing the replenishment bottle 30 elastically abuts against the limiting part 181 of the movable push rod 18. Under normal conditions, the movable push rod 18 moves towards the replenishment bottle 30 to its reset position under the elastic force of the second elastic element 19. At this time, the end of the movable push rod 18 facing the replenishment bottle 30 extends into the mounting cavity 113.
[0123] After the replenishment bottle 30 is installed in the insertion slot 323 of the atomizer 100 along the insertion direction, the outer end face of the cover 33 abuts against the movable push rod 18 and drives it to retract inward. At this time, the second elastic member 19 is compressed and stores force under the pressure of the limiting part 181. When the replenishment bottle 30 is disassembled, the compressed force of the second elastic member 19 is released, which can act on the replenishment bottle 30 and drive it to pop out in the extraction direction.
[0124] In some embodiments, two movable push rods 18 may be provided, each movable push rod 18 being connected to a second elastic element 19. Preferably, the two sets of movable push rods 18 and the second elastic element 19 are respectively arranged on both sides of the atomizing chamber 121, so as to elastically abut against the replenishment bottle 30 from both sides of the liquid guide 13, resulting in more uniform and balanced force application, and less occupation of the internal space of the atomizing device 10, which is conducive to the compact design of the atomizing device 10.
[0125] Correspondingly, guide cavities 122 are provided on both sides of the atomizing chamber 121 of the mounting base 12. Guide ports 123 are provided at both ends of the guide cavities 122, corresponding to the insertion direction of the replenishment bottle 30. The guide ports 123 facing the replenishment bottle 30 connect to the mounting cavity 113. Movable push rods 18 are movably connected to their respective guide cavities 122. The end of the movable push rod 18 facing the replenishment bottle 30 extends movably into the mounting cavity 113 through the corresponding guide port 123, while the end of the movable push rod 18 facing away from the replenishment bottle 30 extends movably out through the corresponding guide port 123. A second elastic element 19 is movably sleeved on the corresponding movable push rod 18 and housed in the guide cavity 122. The movable push rod 18 reciprocates along the insertion direction of the replenishment bottle 30 under the constraint of the guide ports 123.
