Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, specifically to an atomizer and atomization device. Background Technology

[0002] In some atomizing devices, due to the presence of a large volume of atomizing matrix, during use, such as in environments with alternating hot and cold temperatures or high-altitude low-pressure environments, the pressure difference between the storage chamber where the atomizing matrix is ​​located and the external environment can easily cause leakage of the atomizing matrix from the atomization channel.

[0003] The current technical approach to solving the above-mentioned technical problems generally involves wrapping the atomizing core around the liquid storage cotton and then attaching a steel pipe to the liquid storage cotton to control the liquid discharge speed of the liquid tank. However, this solution cannot completely prevent leakage. Utility Model Content

[0004] This application provides an atomizer and an atomizing device to solve the problem of liquid leakage in some usage environments.

[0005] In one embodiment, an atomizer is provided, comprising: a housing assembly including a first liquid chamber, a second liquid chamber, and a liquid guide hole connecting the first and second liquid chambers, wherein the first liquid chamber is used to store an atomizing matrix; an atomizing assembly disposed in the second liquid chamber for atomizing the atomizing matrix into an aerosol; a gate member disposed in the housing assembly; and a stop member abutting and sealing the liquid guide hole, wherein the gate member is configured to move in response to an electrical signal generated by a user's inhalation, exposing the liquid guide hole and forming a liquid path connecting the first and second liquid chambers; the gate member is located outside the liquid path, and the stop member is located within the liquid path.

[0006] In one embodiment, the selector is an electromagnet, and the stop is a metal part; the atomizer further includes an elastic support member, which is located between the stop and the housing assembly and connected to the stop. The selector cooperates with the stop and drives the elastic support member to deform through magnetic attraction, thereby moving the stop.

[0007] In one embodiment, the first end of the elastic support is connected to the stop, and the selector is located on the second end side of the elastic support. When the stop and the selector are located on the same side of the liquid guiding hole, the selector is energized and attracts the stop to move and expose the liquid guiding hole. When the selector is de-energized, the elastic support drives the stop to move and seal the liquid guiding hole under the action of deformation restoring force. Alternatively, when the stop and the selector are located on opposite sides of the liquid guiding hole, the selector is energized and attracts the stop to seal the liquid guiding hole. When the selector is de-energized, the elastic support drives the stop to move and expose the liquid guiding hole under the action of deformation restoring force.

[0008] In one embodiment, the first end of the elastic support is connected to the stop member, and the selector is located at the first end of the elastic support. The second end of the elastic support is connected to the housing assembly. When the stop member and the selector are located on the same side of the liquid guide hole, the selector, when energized, attracts the stop member to move and expose the liquid guide hole. When the selector is de-energized, the elastic support, under the action of deformation restoring force, drives the stop member to move and seal the liquid guide hole. Alternatively, when the stop member and the selector are located on opposite sides of the liquid guide hole, the selector, when energized, attracts the stop member to seal the liquid guide hole. When the selector is de-energized, the elastic support, under the action of deformation restoring force, drives the stop member to move and expose the liquid guide hole.

[0009] In one embodiment, the direction of the magnetic attraction force generated by the energized gate member on the blocking member is parallel to the central axis of the elastic support member.

[0010] In one embodiment, the housing assembly includes: an outer shell, the outer shell including a receiving cavity; a cover, the cover being embedded in the receiving cavity and sealed to the outer shell to form a first liquid reservoir, wherein the liquid guiding hole is formed on the cover; and a bracket, the bracket cooperating with the cover to form a second liquid reservoir, wherein at least a portion of the liquid passage is provided on the bracket.

[0011] In one embodiment, a limiting portion is provided on the end face of the bracket near the elastic support member, and the elastic support member is embedded in the limiting portion; or, the elastic support member is sleeved on the limiting portion.

[0012] In one embodiment, the support includes an electromagnetic cavity with an opening facing away from the cover, and the selector is embedded in the electromagnetic cavity; the atomizer also includes a control board, which is electrically connected to the selector to control the power supply to the selector.

[0013] In one embodiment, the housing assembly further includes an airflow channel, and the atomizer further includes a pneumatic switch electrically connected to the control board. The pneumatic switch is disposed in the airflow channel to detect the air pressure value in the airflow channel, so that the control board controls the power supply of the selector and the atomizing assembly according to the air pressure value.

[0014] In one embodiment, an atomizing device is provided, including an atomizer as described in any of the above-described utility models.

[0015] According to the atomizer of the above embodiment, two independent first and second liquid chambers are connected by a liquid guide hole. The liquid guide hole, through the cooperation of a selector and a stopper, controls the flow of the atomizing matrix from the first liquid chamber into the second liquid chamber. When the atomizer is in use, the stopper can be moved by the selector to open the liquid guide hole and replenish the second liquid chamber, thereby replenishing the liquid volume consumed by the suction in the second liquid chamber. When the atomizer is not in use, the stopper can be used to seal the liquid guide hole to prevent leakage. Attached Figure Description

[0034] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0035] Existing atomizing devices suffer from leakage issues in some operating environments.

[0036] In this application, two independent first liquid chambers 102 and second liquid chambers 103 are connected by a liquid guide hole 101. The liquid guide hole 101, through the cooperation of a selector 4 and a stopper 6, controls the flow of the atomizing matrix from the first liquid chamber 102 into the second liquid chamber 103. When the atomizer is in use, the selector 4 can move the stopper 6 to open the liquid guide hole 101 to replenish the second liquid chamber 103, thereby replenishing the liquid consumed by the second liquid chamber 103. When the atomizer is not in use, the stopper 6 can seal the liquid guide hole 101 to prevent leakage from the atomizer.

[0037] Please refer to Figures 1 to 13 In one embodiment, an atomizer is provided, which may include a housing assembly 1, an atomizing assembly 2, a gate 4, and a stop 6.

[0038] The housing assembly 1 can be understood as a collection of related components that constitute the external shape and internal structural support of the atomizer. The housing assembly 1 may include a first liquid chamber 102, a second liquid chamber 103, and a liquid guide hole 101. The first liquid chamber 102 is used to store the atomizing matrix. The atomizing matrix may include substances such as propylene glycol and flavorings, which, when heated and atomized, produce an aerosol that can be inhaled by the user. The liquid guide hole 101 is provided to connect the first liquid chamber 102 and the second liquid chamber 103.

[0039] The atomizing component 2 is used to atomize the atomizing matrix into an aerosol. The atomizing component 2 is disposed in the second liquid chamber 103 and includes an atomizing channel. Thus, by providing two independent first liquid chambers 102 and second liquid chambers 103, the atomizing matrix in the first liquid chamber 102 is separated from the atomizing channel in the second liquid chamber 103. The atomizing matrix in the first liquid chamber 102 flows from the liquid guide hole 101 into the atomizing component 2 in the second liquid chamber 103. For example, the atomizing component 2 may also include a liquid storage element 21, which adsorbs the atomizing matrix flowing into the second liquid chamber 103. Thus, when the atomizing component 2 is operating, the atomizing matrix in the liquid storage element 21 is heated and atomized to form an aerosol, which flows out of the atomizer along the airflow channel 104 connected to the atomizing channel.

[0040] The selector 4 is installed in the housing assembly 1, and the stop 6 abuts against the sealed liquid guide hole 101. The selector 4 is configured to move the stop 6 away from the liquid guide hole 101 in response to an electrical signal generated by user suction, thereby exposing the liquid guide hole 101 and forming a liquid passage 1301 connecting the first liquid tank 102 and the second liquid tank 103. The selector 4 is located outside the liquid passage 1301, and the stop 6 is located inside the liquid passage 1301. By setting the selector 4 and the stop 6 on the inner and outer sides of the liquid passage 1301 respectively, a more flexible selector 4 can be selected, and the selector 4 can be used to avoid contaminating the liquid passage 1301.

[0041] In summary, when the atomizer is not used, the stopper 6 remains in contact with the sealed liquid guide hole 101, improving the sealing performance of the liquid guide hole 101 and preventing the atomized matrix from flowing out of the first liquid chamber 102 due to pressure differences between the inside and outside of the environment. When the atomizer is used, the electrical signal generated by the user's inhalation activates the gate 4, moving the stopper 6 and thus connecting the liquid path 1301. The atomized matrix in the first liquid chamber 102 can flow through the liquid guide hole 101 to the atomizing component 2 in the second liquid chamber 103. During the user's inhalation, the duration of the user's inhalation is kept consistent with the movement duration of the stopper 6, ensuring a continuous supply of atomized matrix from the first liquid chamber 102 to the second liquid chamber 103. After one inhalation cycle, the gate 4 stops operating, and the atomized matrix in the first liquid chamber 102 is no longer supplied to the second liquid chamber 103, thus achieving immediate replenishment and preventing leakage due to over-replenishment of the atomized matrix.

[0042] In one embodiment, the selector 4 is an electromagnet. An electromagnet refers to an electromagnetic device composed of a coil and a magnetic conductor. When current flows through the coil, the magnetic conductor is magnetized to form a strong magnetic field. When the current in the coil is cut off, the magnetism of the magnetic conductor quickly disappears. The stopper 6 is a metal component, which can be a sheet-like structure or a columnar structure, etc. The metal used in the metal component is a metal that can be magnetically attracted; for example, the metal component can be made of a ferromagnetic material. In one or more embodiments, the stopper 6 can be made of a steel sheet, so that the selector 4 can be energized after the user's suction signal to generate a magnetic attraction force, making it easier for the stopper 6 to be attracted by the selector 4 and move.

[0043] The atomizer may also include an elastic support 5, which is located between the stop member 6 and the housing assembly 1 and connected to the stop member 6. The selector 4 cooperates with the stop member 6, and magnetic attraction drives the elastic support 5 to deform, thereby moving the stop member 6. The elastic support 5 is a support that undergoes elastic deformation under force and returns to its original shape after the external force is removed. For example, the elastic support 5 may include a spring, a spring sheet, or other structures. The elastic support 5 may be located within the housing assembly 1, and its position relative to the stop member 6 is defined by its connection to the housing assembly 1.

[0044] In one embodiment, the atomizer may further include a liquid-guiding seal 3, which is disposed at the liquid-guiding hole 101. For example, the liquid-guiding seal 3 may be located on either side of the liquid-guiding hole 101. The liquid-guiding seal 3 and the abutment 6 are located on the same side of the liquid-guiding hole 101, so that the liquid-guiding hole 101 can be sealed by abutting against the abutment 6. Thus, when the atomizer is not in use, the abutment 6 resets to abut against and seal the liquid-guiding hole 101, thereby maintaining the separation and sealing between the first liquid chamber 102 and the second liquid chamber 103. Furthermore, the atomizing matrix in the second liquid chamber 103, which is connected to the airflow channel 104, is adsorbed by the liquid storage element 21. Even if there is an internal and external pressure difference between the second liquid chamber 103 and the external environment of the atomizer, the atomizing matrix in the second liquid chamber 103 will not leak out along the airflow channel 104.

[0045] In one embodiment, the gate element 4 can be electrically attracted to the stop element 6, and the elastic support element 5 can be deformed by magnetic attraction, thereby moving the stop element 6 away from the liquid-guiding seal element 3, or causing the stop element 6 to approach the liquid-guiding hole 101 and abut against the liquid-guiding seal element 3. When the gate element 4 is de-energized, the elastic support element 5 deforms and recovers, thereby moving the stop element 6 closer to the liquid-guiding hole 101 and abut against the liquid-guiding seal element 3, or moving the stop element 6 away from the liquid-guiding seal element 3.

[0046] In one embodiment, the elastic support 5 has a first end and a second end at its two ends along its axial direction. For example, when the first liquid tank 102 and the second liquid tank 103 are distributed vertically, the first end of the elastic support 5 can be the upper end and the second end can be the lower end. As another example, when the first liquid tank 102 and the second liquid tank 103 are distributed horizontally, the first end of the elastic support 5 can be the left end and the second end can be the right end.

[0047] The first end of the elastic support 5 is connected to the abutment 6. The connection method includes abutment or fixed connection. In some embodiments, if the first liquid tank 102 and the second liquid tank 103 are distributed vertically, the elastic support 5 and the abutment 6 can be in abutment. Here, abutment can be understood as no fixed connection between the abutment 6 and the elastic support 5, and contact is maintained by pressure.

[0048] For example, the contact force between the elastic support 5 and the stop 6 can be generated by the deformation force of the elastic support 5 (including tensile deformation and compressive deformation). Alternatively, the contact force between the elastic support 5 and the stop 6 can be generated by the gravity of the stop 6. Or, the contact force between the elastic support 5 and the stop 6 can be generated by the gravity of the stop 6 and the hydraulic pressure of the atomizing matrix in the first liquid tank 102. The selector 4 is located on the second end side of the elastic support 5, that is, the elastic support 5 is located between the selector 4 and the stop 6. Thus, the compression of the elastic support 5 can be controlled by generating a magnetic attraction force through the energization of the selector 4, thereby realizing the opening and closing of the liquid passage of the liquid guide hole 101.

[0049] In some implementations, refer to Figure 3 , Figure 4 as well as Figure 5 As shown, if the abutment 6 and the selector 4 are located on the same side of the liquid guiding hole 101, for example, both the abutment 6 and the selector 4 are located on the end face of the liquid guiding hole 101 near the first liquid chamber 102, or both the abutment 6 and the selector 4 are located on the end face of the liquid guiding hole 101 away from the first liquid chamber 102. When the selector 4 is energized, it attracts the abutment 6, thereby causing the elastic support 5 located between the selector 4 and the abutment 6 to deform and compress. It moves away from the liquid guiding seal 3 to open the liquid guiding hole 101, thereby allowing the atomized matrix in the first liquid chamber 102 to flow through the liquid guiding hole 101 to the second liquid chamber 103. When the selector 4 is de-energized, the elastic support 5, under the action of deformation restoring force, drives the abutment 6 to move closer to the liquid guiding seal 3 to seal the liquid guiding hole 101.

[0050] In one or more embodiments, reference is made to Figure 4 and Figure 5As shown, when the blocking member 6 and the selector 4 are located on the same side of the liquid guide hole 101, and the first liquid chamber 102 and the second liquid chamber 103 are distributed vertically, when the selector 4 is de-energized, the blocking member 6 is subjected to its own gravity, the hydraulic pressure of the atomizing matrix in the first liquid chamber 102, and the elastic force of the elastic support member 5. At this time, the upward elastic force is greater than the downward gravity and the cumulative pressure of the hydraulic pressure, and the liquid guide hole 101 is in a sealed state. When the selector 4 is energized, the downward magnetic attraction, the downward gravity, and the cumulative pressure of the hydraulic pressure are greater than the elastic force. The elastic support member 5 is compressed downward, and the blocking member 6 moves away from the liquid guide hole 101, thereby opening the liquid guide hole 101, and the atomizing matrix in the first liquid chamber 102 flows to the second liquid chamber 103 through the liquid guide hole 101.

[0051] In one or more embodiments, when the blocking member 6 and the selector 4 are located on the same side of the liquid guide hole 101, and the first liquid chamber 102 and the second liquid chamber 103 are distributed to the left and right, the elastic support member 5 and the blocking member 6 can be fixedly connected. When the selector 4 is de-energized, the blocking member 6 is subjected to hydraulic pressure in the horizontal direction and the elastic force of the elastic support member 5. At this time, the hydraulic pressure is less than the elastic force, and the liquid guide hole 101 is in a sealed state. When the selector 4 is energized, the cumulative pressure value of the hydraulic pressure and magnetic attraction in the horizontal direction is greater than the elastic force. The elastic support member 5 is compressed to one side, and the blocking member 6 moves away from the liquid guide hole 101, thereby opening the liquid guide hole 101, and the atomizing matrix in the first liquid chamber 102 flows to the second liquid chamber 103 through the liquid guide hole 101.

[0052] In one embodiment, reference is made to Figure 6 and Figure 7 As shown, when the stop member 6 and the selector member 4 are located on opposite sides of the liquid guide hole 101, that is, the spring support member will pass through the liquid guide hole 101. The stop member 6 can be located on the end side of the liquid guide hole 101 near the first liquid tank 102, and the selector member 4 can be located on the end side of the liquid guide hole 101 away from the first liquid tank 102. If the stop member 6 is located on the end side of the liquid guide hole 101 away from the first liquid tank 102, the selector member 4 can be located on the end side of the liquid guide hole 101 near the first liquid tank 102. The magnetic attraction generated by the energized selector member 4 will attract the stop member 6, thereby compressing the elastic support member 5 located between the selector member 4 and the stop member 6. The stop member 6 will move closer to the liquid guide seal member 3 to seal the liquid guide hole 101. When the selector member 4 is de-energized, the elastic support member 5, under the action of deformation restoring force, will drive the stop member 6 to move away from the liquid guide seal member 3 to open the liquid guide hole 101.

[0053] In one embodiment, reference is made to Figure 8 , Figure 9 , Figure 10 as well as Figure 11As shown, the first end of the elastic support 5 is connected to the stop 6, and the selector 4 is located on the side of the first end of the elastic support 5. The second end of the elastic support 5 is connected to the housing assembly 1. That is, the stop 6 and the selector 4 are located on the same side of the elastic support 5.

[0054] In one or more embodiments, reference is made to Figure 8 and Figure 9 As shown, when the stop member 6 and the selector member 4 are located on the same side of the liquid guiding hole 101 (simultaneously located on the end side of the liquid guiding hole 101 near the first liquid tank 102, or simultaneously located on the end side of the liquid guiding hole 101 away from the first liquid tank 102), the elastic support member 5 will penetrate through the liquid guiding hole 101. When the selector member 4 is energized, it generates a magnetic attraction force, which will attract the stop member 6, thereby causing the elastic support member 5 located between the selector member 4 and the stop member 6 to stretch, thus attracting the stop member 6 to move away from the liquid guiding seal member 3, in order to open the liquid guiding hole 101. When the selector member 4 is de-energized, the elastic support member 5, under the action of deformation restoring force, drives the stop member 6 to move closer to the liquid guiding seal member 3, in order to seal the liquid guiding hole 101.

[0055] In one or more embodiments, reference is made to Figure 10 and Figure 11 As shown, the stopper 6 and the selector 4 are located on opposite sides of the liquid guide hole 101. The stopper 6 can be located on the end of the liquid guide hole 101 closer to the first liquid tank 102, while the selector 4 is located on the end of the liquid guide hole 101 farther from the first liquid tank 102. When the selector 4 is energized, it generates a magnetic attraction force to attract the stopper 6, thereby causing the spring support member fixedly connected to the stopper 6 to stretch. The stopper 6 moves closer to the liquid guide seal 3 to seal the liquid guide hole 101. When the selector 4 is de-energized, the elastic support member 5, under the action of deformation restoring force, drives the stopper 6 to move away from the liquid guide seal 3 to open the liquid guide hole 101.

[0056] In one embodiment, reference is made to Figure 4 As shown, the direction of the magnetic attraction force generated by the energized selector 4 on the resisting member 6 is parallel to the central axis of the elastic support member 5.

[0057] In this embodiment, considering that the elastic support 5 is located between the blocking member 6 and the selecting member 4, the direction of the magnetic attraction force generated by the selecting member 4 on the blocking member 6 when energized is parallel to the central axis of the elastic support 5. This ensures that the radial component of the magnetic attraction force along the elastic support 5 is zero or negligible. Under the action of the blocking member 6, the elastic support 5 undergoes compressive or tensile deformation along its axial direction. This prevents the elastic support 5 from undergoing radial deformation due to the radial component force, thus reducing the service life and functional reliability of the elastic support 5.

[0058] In one embodiment, reference is made to Figure 3As shown, the housing assembly 1 may include an outer shell 11, a cover 12, and a bracket 13.

[0059] The outer casing 11 includes a receiving cavity 1101, which provides mounting space for internal components of the atomizer. For example, it provides mounting space for the cover 12 and the bracket 13. The cover 12 is embedded in the receiving cavity 1101 and is sealed to the outer casing 11 to form a first liquid reservoir 102, wherein a liquid guide hole 101 is formed on the cover 12. In one or more embodiments, the receiving cavity 1101 has an opening, and the inner surface of the outer casing 11 is provided with a mounting groove. The cover 12 is located at the mounting groove and forms a clearance fit and sealing connection with the outer casing 11, thereby forming the first liquid reservoir 102. The sealing connection between the cover 12 and the outer casing 11 can be achieved by providing a liquid reservoir seal at the connection between the cover 12 and the outer casing 11, or by providing a liquid reservoir seal covering the connection between the two at the end face of the cover 12 away from the first liquid reservoir 102. In some embodiments, if the liquid reservoir seal and the liquid guiding seal 3 can be an integral structure, the integrated design can improve the sealing performance while reducing the production cost of the seal. The liquid reservoir seal and the liquid guiding seal 3 can be made of soft materials. Soft materials can include, but are not limited to, silicone, rubber, etc.

[0060] The bracket 13 is used to fix the components in the accommodating cavity 1101, which can improve the positional assembly accuracy between the components in a small space. For example, the bracket 13 can be assembled on the side of the outer shell 11 away from the first liquid tank 102 to abut against the cover 12 to form the assembly positioning of the cover 12, or to abut against the liquid tank seal to form the assembly positioning of the liquid tank seal. The cover 12 can be a plate-like structure with a flange. The bracket 13 and the cover 12 cooperate to form the second liquid tank 103. The atomizing component 2 is located in the second liquid tank 103 and can be assembled and positioned by the bracket 13, or by the bracket 13 and the cover 12.

[0061] A liquid guide hole 101 is formed on the cover 12 and is a through hole penetrating the wall thickness of the cover 12. For example, the liquid guide hole 101 can be located at the bottom or lower side of the first liquid chamber 102. Thus, when the liquid guide hole 101 is not sealed, the atomized matrix located in the first liquid chamber 102 flows from the liquid guide hole 101 to the second liquid chamber 103 by gravity. At least a portion of the liquid passage 1301 is provided on the support 13, connecting the liquid guide hole 101 and the second liquid chamber 103. That is, the first liquid tank 102 and the second liquid tank 103 containing the atomizing matrix can be separated by the liquid passage 1301, so that the atomizing matrix in the first liquid tank 102 will not directly contact the atomizing component 2 in the second liquid tank 103 through the liquid guide hole 101. For example, it will not directly contact the liquid storage element 21 in the atomizing component 2. This avoids the liquid storage element 21 from easily absorbing too much atomizing matrix and becoming oversaturated. When there is atomizing matrix remaining at the bottom of the second liquid tank 103 that has not been absorbed by the liquid storage element 21, the atomizing matrix in the second liquid tank 103 will leak outward along the airflow channel 104 when there is an internal and external pressure difference between the second liquid tank 103 and the external environment of the atomizer.

[0062] In one embodiment, reference is made to Figure 3 , Figure 4 , Figure 12 as well as Figure 13 As shown, the second liquid tank 103 has a liquid guiding notch 1302 on the support 13 near the liquid passage 1301. The height of the liquid guiding notch 1302 is higher than the bottom height of the liquid passage 1301.

[0063] In this embodiment, the liquid guiding notch 1302 is used to guide the atomized matrix in the liquid path 1301 into the second liquid chamber 103. The height of the liquid guiding notch 1302 is higher than the bottom height of the liquid path 1301, so that after the liquid guiding hole 101 is closed, a portion of the atomized matrix in the liquid path 1301 can flow into the second liquid chamber 103 through the liquid guiding notch 1302 and be adsorbed by the liquid storage element 21. Another portion of the atomized matrix in the liquid path 1301 is stored in the area below the liquid guiding notch 1302, thereby avoiding direct contact between the atomized matrix in this area and the liquid storage element 21. This prevents the liquid storage element 21 from becoming oversaturated with too much atomized matrix and dripping to the bottom of the second liquid chamber 103 with atomized matrix that has not been adsorbed by the liquid storage element 21, which could lead to leakage of the atomized matrix in the second liquid chamber 103 along the airflow channel 104 when there is a pressure difference between the inside and outside of the environment.

[0064] In one embodiment, reference is made to Figure 3 , Figure 4 as well as Figure 13As shown, a limiting part 131 is provided on the end face of the bracket 13 near the elastic support member 5, and the elastic support member 5 is embedded in the limiting part 131. The limiting part 131 is used to fix the end of the elastic support member 5 near the gate member 4. For example, the elastic support member 5 can be limited in the radial direction by being embedded in the limiting part 131. In one or more embodiments, at least one guide groove flush with the bottom of the limiting part 131 can be uniformly formed on the limiting part 131, thereby avoiding the situation where the atomized matrix remains in the cavity formed by the limiting part 131 and cannot be discharged.

[0065] In one embodiment, the elastic support 5 can be sleeved on the outer surface of the limiting part 131 to limit the elastic support 5 in the radial direction. The elastic support 5 and the limiting part 131 can be fitted with an interference fit, clearance fit, or other methods. The limiting part 131 and the elastic support 5 can be an integral structure, which can reduce the number of parts in the atomizer and also reduce the production cost of the atomizer.

[0066] In one embodiment, reference is made to Figure 3 As shown, the support 13 includes an electromagnetic cavity 1303 with its opening facing away from the cover 12, and a selector 4 is embedded in the electromagnetic cavity 1303. The electromagnetic cavity 1303 can be disposed on the back side of the end face of the support 13 where the elastic support 5 is mounted, and the selector 4 can be clearance-fitted with the electromagnetic cavity 1303 to achieve positioning of the selector 4. The atomizer also includes a control board 7, which serves as an electronic controller for monitoring and adjusting the atomizer's operating status. For example, the control board 7 is electrically connected to the selector 4 to control the on / off state of the selector 4.

[0067] In one embodiment, reference is made to Figure 3 As shown, the housing assembly 1 also includes an airflow channel 104, and the atomizer also includes a pneumatic switch 8 electrically connected to the control board 7. The pneumatic switch 8 is disposed in the airflow channel 104 to detect the air pressure value in the airflow channel 104, so that the control board 7 controls the power supply to the selector 4 and the atomizing assembly 2 according to the air pressure value. For example, the pneumatic switch 8 can be integrated into the control board 7. For example, a portion of the housing 11 can form a mouthpiece for the user to inhale, with an air outlet 1102 communicating with the airflow channel 104. An air inlet 1103 is also provided in the area of ​​the housing 11 near the support 13, and the air inlet 1103 is used to guide external airflow into the airflow channel 104. When suction is applied at the air outlet 1102 to create a negative pressure in the airflow channel 104, the pneumatic switch 8 is activated under the negative pressure. At this time, the control board 7 can control the atomizing component 2 to work and heat up, so as to heat the atomizing matrix adsorbed by the liquid storage element 21 into an aerosol, and discharge it from the airflow channel 104 to the air outlet 1102.

[0068] Furthermore, when the pneumatic switch 8 detects that the user is suctioning, the control board 7 can energize or de-energize the selector 4, causing it to generate or lose magnetic attraction. This moves the stopper 6 in the liquid path 1301, exposing the liquid guide hole 101 and opening the liquid path 1301. Thus, the atomized matrix in the first liquid chamber 102 flows along the liquid path 1301 to the second liquid chamber 103 for replenishment. This ensures that the amount of atomized matrix consumed during suction is replenished in real-time through the liquid path 1301, without requiring additional control structures. When the pneumatic switch 8 detects that the user has finished suctioning, the control board 7 can de-energize or energize the selector 4, causing the stopper 6 to move and abut against the sealing liquid guide hole 101. This improves the sealing of the atomized matrix in the first liquid chamber 102, preventing leakage due to pressure differences between the inside and outside environment.

[0069] Please refer to Figure 14 In one embodiment, an atomizing device is provided, which may include an atomizer and an atomizing host 9 as described in any of the above embodiments. The atomizing host 9 includes a power supply component for supplying electrical energy to the atomizer. The atomizing device may be a disposable product or a refillable product. For a disposable atomizing device, the atomizer and the atomizing host 9 are fixedly connected. For a refillable atomizing device, the atomizer and the atomizing host 9 are detachably connected, and the atomizer and the atomizing host 9 can be replaced as needed.

[0070] In summary, this application provides an atomizer and an atomizing device. This application embodiment allows two independent first liquid chambers 102 and second liquid chambers 103 to be connected via a liquid guide hole 101. The liquid guide hole 101, through the cooperation of a selector 4 and a stopper 6, controls the flow of the atomizing matrix from the first liquid chamber 102 into the second liquid chamber 103. When the atomizer is in use, the selector 4 can move the stopper 6 to open the liquid guide hole 101, replenishing the second liquid chamber 103 and thus refilling the liquid consumed by the second liquid chamber 103. When the atomizer is not in use, the stopper 6 can seal the liquid guide hole 101 to prevent leakage.
