Description

Technical Field

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

[0002] Electronic atomizing devices typically have a liquid reservoir for storing a liquid aerosol matrix, and a liquid passage designed to work with the liquid reservoir. The liquid aerosol matrix in the liquid reservoir can be transported to the atomizing core in the atomizer through the liquid passage, where it is heated and atomized to generate an aerosol.

[0003] The liquid storage chamber of this type of atomizer relies on gravity for drainage. The drainage process is easily affected by changes in pressure and temperature within the liquid storage chamber, making it difficult to control the drainage process. Utility Model Content

[0009] A first disc and a second disc are arranged along the extension direction of the liquid passage. The first disc is provided with a first liquid guiding hole, and the second disc is provided with a second liquid guiding hole. The first liquid guiding hole and the second liquid guiding hole are staggered. When the first disc and the second disc move relative to each other in the axial and / or radial direction, the first liquid guiding hole and the second liquid guiding hole have an initial state of staggered closure and an open state of liquid communication.

[0010] And a vibration component configured to drive the first disc and / or the second disc to vibrate, so that the first liquid guiding hole and the second liquid guiding hole switch between the initial state and the open state.

[0011] In one embodiment, the vibration component is configured to drive the first disc and / or the second disc to vibrate axially, such that at least one of the first disc and the second disc moves away from and closer to the other, thereby intermittently forming a fluid-guiding gap between them that connects the first fluid-guiding through hole and the second fluid-guiding through hole.

[0012] In one embodiment, the first disc and the second disc each have a contact surface on their sides that are close to each other for contacting each other. The contact surface of one of the first discs and the second disc is provided with a protrusion, and the contact surface of the other disc is provided with a recess for the protrusion to be inserted.

[0013] In one embodiment, the first disc is disposed on the side of the second disc near the liquid storage cavity;

[0014] The protrusion is disposed on the contact surface of the first disc body, and the first liquid guiding hole is disposed corresponding to the protrusion and penetrates the protrusion;

[0015] The recessed portion is disposed on the contact surface of the second disk body, and the recessed portion and the second liquid guiding hole are staggered. The contact surface of the second disk body is provided with a liquid guiding groove that connects the adjacent recessed portion and the second liquid guiding hole, so that when the vibrating component drives the first disk body and / or the second disk body to vibrate, the liquid aerosol matrix in the recessed portion can be squeezed into the adjacent second liquid guiding hole by the protrusion.

[0016] In one embodiment, the bottom wall of the liquid guiding groove gradually moves away from the first disc body from the side connected to the recessed portion towards the side connected to the liquid guiding hole.

[0018] In one embodiment, the first disc and the second disc are disposed in the hollow cavity along the axial direction of the hollow cavity, and the sidewall of one of them is interference-fitted with the cavity wall of the hollow cavity, while the sidewall of the other is clearance-fitted or transition-fitted with the cavity wall of the hollow cavity, so that one of the first disc and the second disc is a fixed disc fixedly disposed in the hollow cavity, and the other is a movable disc movably disposed in the hollow cavity;

[0019] The vibration component includes a vibrator and an elastic element; an installation space is formed between the first disc and the second disc, and the vibrator is disposed in the installation space; a limiting step surface is provided in the hollow cavity on the side of the movable disc away from the fixed disc, and the elastic element is disposed between the movable disc and the limiting step surface to provide elastic force to the movable disc toward the fixed disc.

[0020] In one embodiment, the cross-section of the elastic element is triangular or trapezoidal, and the cross-sectional width of the elastic element on the side closer to the movable disk is greater than the cross-sectional width on the side farther from the movable disk.

[0024] The atomizer described in any of the above embodiments is disposed within the housing of the device;

[0025] And a power supply component for supplying power to the atomizer.

[0026] According to the atomizer of the above embodiment, in one usage state, the liquid storage chamber is located above the liquid passage, so that the liquid aerosol matrix in the liquid storage chamber can automatically flow into the liquid passage under the action of gravity; by setting a drain control component, when not activated, the first liquid guide hole and the second liquid guide hole are in an initial state of misalignment and closure, so that the liquid passage is blocked and cannot drain, which helps to prevent the atomizer from leaking; when draining is required, the drain control component is adjusted to the open state, and the vibration component drives the first disc and / or the second disc to vibrate. During the vibration, the first liquid guide hole and the second liquid guide hole can be intermittently connected to the liquid to drain, so that the atomizer can control whether to drain as needed.

[0027] The vibration of the liquid control component can also promote the full mixing of various components in the liquid aerosol matrix, which helps to maintain a uniform inhalation taste and reduce flavor decay during atomizer use. Attached Figure Description

[0044] In this embodiment, a drain control component 300 is provided in the liquid passage 200 through which the liquid aerosol matrix is ​​discharged from the liquid storage chamber 100. When draining is not required, the first liquid guiding hole 311 on the first disc 310 and the second liquid guiding hole 321 on the second disc 320 are in an initial state of misalignment and isolation, and the first disc 310 and the second disc 320 cooperate to isolate the liquid passage 200. When draining is required, the vibration component 330 is controlled to drive the first disc 310 and / or the second disc 320 to vibrate, so that the first liquid guiding hole 311 and the second liquid guiding hole 321 can move to the open state of liquid communication, and repeatedly switch between the initial state and the open state, so that the liquid aerosol matrix can be discharged through the drain control component 300, thereby realizing the control of the opening and closing of the liquid passage 200, which makes it convenient for the atomizer to control whether to drain as needed.

[0045] An embodiment of the atomizer in this application:

[0046] In one embodiment, please refer to Figures 1-4 The atomizer has a liquid storage chamber 100, a liquid passage 200, and a liquid discharge control component 300.

[0047] The liquid storage chamber 100 is used to store the liquid aerosol matrix. In some embodiments, please refer to... Figure 1 The atomizer may include a housing 400 and a liquid storage container 500. The housing 400 has a mounting cavity 410, and the liquid storage container 500 is mounted in the mounting cavity 410 in a detachable or non-detachable manner, so that the inner cavity of the liquid storage container 500 can serve as a liquid storage chamber 100. In other embodiments, the liquid storage chamber 100 may also be integrally formed in the housing 400, or the liquid storage chamber 100 may be formed by the housing 400 and components such as a bracket and a base.

[0048] Please refer to Figure 1 and Figure 2 The liquid passage 200 is in liquid communication with the liquid storage chamber 100 and is used to allow the liquid aerosol matrix in the liquid storage chamber 100 to be discharged under gravity. In some embodiments where the liquid storage chamber 100 is provided by the liquid storage container 500, the liquid storage container 500 may have a container opening 510, which can form at least part of the liquid passage 200. In other embodiments, the liquid passage 200 may also be formed by a drain hole or drain groove provided on the cavity wall of the liquid storage chamber 100.

[0049] Those skilled in the art will understand that, in order to enable the liquid aerosol matrix in the reservoir 100 to automatically enter the liquid passage 200 when the atomizer is in use, the atomizer can be configured such that the reservoir 100 is located above the liquid passage 200 when in use, so that the liquid aerosol matrix in the reservoir 100 can automatically enter the liquid passage 200 under the action of gravity.

[0050] In one embodiment, please refer to Figure 1 and Figure 2 The atomizer may include a housing 400 and a liquid reservoir 500. The housing 400 is located in... Figure 1 The upper side of the image shows a mounting cavity 410 and an air outlet channel 420 arranged side by side, while the lower side shows a buffer cavity 430. A liquid storage container 500 is disposed within the mounting cavity 410. A communication port is provided on the cavity wall between the mounting cavity 410 and the buffer cavity 430. The container opening 510 of the liquid storage container 500 is inserted and fixed into the communication port, thereby connecting the liquid storage cavity 100 and the buffer cavity 430. That is, the liquid storage container 500... Figure 1 As shown, it is inserted upside down into the mounting cavity 410. The buffer cavity 430 is provided with an atomizing tube 431 and a liquid storage component 432. The liquid storage component 432 covers the atomizing tube 431 and is used to absorb the liquid aerosol matrix discharged into the buffer cavity 430 and supply it to the atomizing tube 431. The atomizing tube 431 has an atomizing core for atomizing the liquid aerosol matrix to form an aerosol. The atomizing tube 431 is connected to the end of the air outlet channel 420 near the buffer cavity 430. The air outlet of the air outlet channel 420 is located at the end away from the buffer cavity 430, that is, on the upper surface of the housing 400 in the illustrated view.

[0051] By adopting the above-mentioned atomizer structure, the liquid storage container 500 can be in an inverted state with the container opening 510 facing downward during suction, so that the liquid aerosol matrix in the liquid storage chamber 100 can automatically enter the liquid passage 200 under the action of gravity.

[0052] The drain control assembly 300 is used to control the on / off state of the liquid passage 200 so that the atomizer can control whether to drain liquid as needed. In one embodiment, please refer to... Figures 2-4 The drainage control component 300 is disposed in the liquid passage 200 and includes a first disc 310, a second disc 320, and a vibration component 330.

[0053] The first disc 310 and the second disc 320 are arranged along the extension direction of the liquid passage 200. The first disc 310 is provided with a first liquid guiding hole 311, and the second disc 320 is provided with a second liquid guiding hole 321. The first liquid guiding hole 311 and the second liquid guiding hole 321 are staggered. When the first disc 310 and the second disc 320 move relative to each other in the axial and / or radial directions, the first liquid guiding hole 311 and the second liquid guiding hole 321 have an initial state of staggered closure and an open state of liquid communication.

[0054] The vibration component 330 is configured to drive the first disc 310 and / or the second disc 320 to vibrate, so that the first liquid guiding hole 311 and the second liquid guiding hole 321 switch between an initial state and an open state.

[0055] When drainage is not required, the first liquid guiding hole 311 and the second liquid guiding hole 321 are in an initial state of misalignment and closure, and the first disc 310 and the second disc 320 isolate the liquid passage 200. When drainage is required, the vibration component 330 drives the first disc 310 and / or the second disc 320 to vibrate, so that the relative positions of the first liquid guiding hole 311 and the second liquid guiding hole 321 change back and forth, so as to repeatedly switch between the initial state of misalignment and closure and the open state of liquid connection, and continuously connect during the switching process, thereby draining the liquid.

[0056] The first disc 310, the second disc 320, and the vibrating component 330 work together to allow the atomizer to control whether to discharge liquid as needed. Furthermore, the vibration of the discharge control component 300 helps overcome the effects of pressure and temperature changes within the liquid storage chamber 100 and the surface tension of the liquid aerosol matrix on the discharge process, ensuring a stable discharge rate. It also promotes thorough mixing of the various components in the liquid aerosol matrix, helping to maintain a uniform inhalation experience and reduce flavor degradation during atomizer use. In addition, compared to using a fluid pump as the discharge control component 300, this method is less expensive and requires less space, thus reducing the design and manufacturing costs of the atomizer.

[0057] Those skilled in the art should understand that the liquid discharge control component 300 being disposed in the liquid passage 200 can be understood as the liquid discharge control component 300 being completely disposed in the liquid passage 200, or it can be understood as being partially disposed in the liquid passage 200. For example, only the portion of the first disc 310 having the first liquid guiding hole 311 and the portion of the second disc 320 having the second liquid guiding hole 321 are disposed in the liquid passage 200.

[0058] The liquid passage 200 can be arranged in a straight line, a curved line or other shapes as needed, and the cross-section of the liquid passage 200 can be circular, triangular, square or other shapes.

[0059] One or more of the first liquid guiding hole 311 and the second liquid guiding hole 321 can be arranged on the corresponding first disk 310 or second disk 320, as long as the design and usage requirements are met.

[0060] In one embodiment, the vibration component 330 may be configured to drive the first disc 310 and / or the second disc 320 to vibrate along their own axial direction, such that at least one of the first disc 310 and the second disc 320 moves away from and closer to the other, so as to intermittently form a liquid-guiding gap between the two, connecting the first liquid-guiding hole 311 and the second liquid-guiding hole 321, thereby allowing the liquid aerosol matrix to pass through the drainage control component 300.

[0061] The arrangement of the vibrating component 330 driving the first disc 310 and / or the second disc 320 to vibrate along its own axis helps to drive the liquid aerosol matrix to vibrate during the liquid discharge process, reduces the possibility of the liquid aerosol matrix forming an interfacial liquid film due to gas pressure and surface tension, and facilitates the discharge of the liquid aerosol matrix.

[0062] In other embodiments, the vibration component 330 may also be configured to drive the first disc 310 and / or the second disc 320 to vibrate radially, so that the first liquid guiding hole 311 and the second liquid guiding hole 321 can be intermittently directly connected, thereby allowing the liquid aerosol matrix to pass through. The vibration component 330 may also be configured to drive the first disc 310 and / or the second disc 320 to vibrate axially and radially, and by adjusting the axial and radial amplitudes, the first disc 310 and / or the second disc 320 can vibrate in any other direction that meets the design and usage requirements.

[0063] In a further embodiment, the first disc 310 and the second disc 320 each have a contact surface for contacting each other on the side that is close to each other. One of the contact surfaces of the first disc 310 and the second disc 320 is provided with a protrusion 312, and the other contact surface is provided with a recess 322 for the protrusion 312 to be inserted.

[0064] The coordinated arrangement of the protrusion 312 and the recess 322 facilitates the guidance and positioning of the first disc 310 and / or the second disc 320, corrects possible positional deviations during vibration, and ensures that after the vibrating component 330 stops, the first liquid guiding hole 311 and the second liquid guiding hole 321 can return to their initial misaligned and closed state, which helps to prevent leakage.

[0065] In one embodiment, the first disc 310 is disposed on the side of the second disc 320 near the liquid storage chamber 100; the protrusion 312 is disposed on the contact surface of the first disc 310, the first liquid guiding hole 311 is correspondingly disposed with the protrusion 312, and can penetrate the protrusion 312 along the axial direction or other directions of the first disc 310; the recess 322 is disposed on the contact surface of the second disc 320, the recess 322 and the second liquid guiding hole 321 are staggered, and the contact surface of the second disc 320 is provided with a liquid guiding groove 323 connecting the adjacent recess 322 and the second liquid guiding hole 321, so that when the vibrating component 330 drives the first disc 310 and / or the second disc 320 to vibrate, the liquid aerosol matrix in the recess 322 can be squeezed into the adjacent second liquid guiding hole 321 by the protrusion 312.

[0066] By adopting the above-described configuration, when drainage is required, the liquid aerosol matrix can be discharged into the recessed portion 322 through the first liquid guiding hole 311, where it gathers. Then, during the process of the protrusion 312 entering the recessed portion 322, the liquid aerosol matrix in the recessed portion 322 can be squeezed into the liquid guiding groove 323 by the protrusion 312, and then discharged through the adjacent second liquid guiding hole 321. This helps to promote the liquid aerosol matrix to enter the second liquid guiding hole 321, reduce the residue of the liquid aerosol matrix between the contact surfaces of the first disc 310 and the second disc 320, and thus improve the drainage control effect.

[0067] Those skilled in the art will understand that the bottom wall of the liquid guiding groove 323 can be configured such that the side connected to the recess 322 gradually moves away from the first disc 310 towards the side connected to the liquid guiding hole, so that the liquid aerosol matrix entering the liquid guiding groove 323 can actively flow to the second liquid guiding hole 321 and is less likely to flow back to the recess 322, which helps to ensure smooth drainage.

[0068] In one embodiment, please refer to Figure 2 The atomizer includes a liquid storage container 500, a liquid storage chamber 100 disposed within the liquid storage container 500, a container opening 510, and a sealing sleeve 600 disposed within the container opening 510. The sealing sleeve 600 has a hollow inner cavity 610, which forms at least a portion of the liquid passage 200. A drain control assembly 300 is disposed within the hollow inner cavity 610. By providing the sealing sleeve 600, resonance is reduced, lowering the risk of leakage around the drain control assembly 300. In other embodiments, the sealing sleeve 600 may also be disposed at other locations within the liquid passage 200.

[0069] In a further embodiment, the first disc 310 and the second disc 320 are arranged axially in the hollow cavity 610, and the sidewall of one of them is interference-fitted with the cavity wall of the hollow cavity 610, while the sidewall of the other is clearance-fitted or transition-fitted with the cavity wall of the hollow cavity 610, so that one of the first disc 310 and the second disc 320 serves as a fixed disc fixedly arranged in the hollow cavity 610, and the other serves as a movable disc movably arranged in the hollow cavity 610.

[0070] For example, the second disc 320 has an outwardly expanding flange 324 on the side opposite to the first disc 310. The outer peripheral wall of the outwardly expanding flange 324 is press-fitted with the cavity wall of the hollow inner cavity 610 so that the second disc 320 is snapped and fixed in the hollow inner cavity 610, serving as a fixed disc. The first disc 310 is disposed on the side of the second disc 320 near the liquid storage cavity 100. The maximum outer diameter of the first disc 310 is slightly smaller than the diameter of the hollow inner cavity 610, so that there is a gap between the first disc 310 and the cavity wall of the hollow inner cavity 610, serving as a movable disc.

[0071] The vibration component 330 may include a vibrator 331 and an elastic element 332; an installation space is formed between the first disc 310 and the second disc 320, and the vibrator 331 is disposed in the installation space; a limiting step surface 611 is provided in the hollow inner cavity 610 on the side of the movable disc away from the fixed disc, and the elastic element 332 is disposed between the movable disc and the limiting step surface 611 to provide elastic force to the movable disc in the direction of the fixed disc so that the movable disc and the fixed disc are pressed together and the liquid passage 200 is blocked.

[0072] For example, the first disc 310 and the second disc 320 may each have an annular clearance groove on the side that is close to each other. The two annular clearance grooves together form an installation space. The vibrator 331 is installed in the installation space. The vibrator 331 can be an annular Z-axis vibration motor, which drives the first disc 310 to move back and forth along its axial direction away from and towards the second disc 320.

[0073] The elastic element 332 can be annular and can be adhered to the end face of the movable disc facing away from the fixed disc. The side of the elastic element 332 facing away from the movable disc abuts against the limiting step surface 611 to provide elastic force to the movable disc in the direction of the fixed disc. This allows the distance between the first disc body 310 and the second disc body 320 in the initial state to be reduced to a state where the first liquid guiding hole 311 and the second liquid guiding hole 321 are difficult to connect with liquid, for example, the distance is reduced to 0.2 mm, thereby reducing the risk of leakage. The elastic element 332 should also remain intact when the movable disc moves to the maximum distance with the fixed disc, for example, when the movable disc is displaced 0.3 mm in the axial direction, allowing the first liquid guiding hole 311 and the second liquid guiding hole 321 to connect with liquid. Therefore, the elastic element 332 can be made of a material with a high elastic coefficient, such as silicone material with high elasticity.

[0074] In some embodiments, the cross-section of the elastic element 332 can be triangular or trapezoidal, and the cross-sectional width of the elastic element 332 on the side closer to the movable disk is greater than the cross-sectional width on the side farther from the movable disk, so that when the vibrator 331 drives the movable disk to vibrate, the deformation part of the elastic element 332 is mainly located on the side farther from the movable disk, which helps to reduce the influence of deformation on the bonding strength and maintain the bonding stability.

[0075] In other embodiments, the cross-section of the elastic element 332 may also be hexagonal or other shapes. The elastic element 332 may also be fixed to the movable disc or the limiting step surface 611 by snap-fit, welding or other means.

[0076] In another embodiment, the vibration component 330 may also include only the vibrator 331, and the first disc 310 may be connected to the vibrator 331 so that the vibrator 331 can independently drive the first disc 310 to vibrate.

[0077] To reduce the risk of displacement of the fixed disk due to vibration, in one embodiment, a retaining ring 620 may be fixedly disposed in the hollow cavity 610. The retaining ring 620 is disposed on the side of the fixed disk opposite to the movable disk, and is used to restrict the movement of the fixed disk. Exemplarily, the sidewall of the retaining ring 620 is interference-fitted with the cavity wall of the hollow cavity 610 to snap-fit ​​and fix it in the hollow cavity 610, thereby limiting the contact of the fixed disk. In other embodiments, the retaining ring 620 may also be fixed in the hollow cavity 610 by bonding, welding, or other means.

[0078] In a further embodiment, please refer to Figure 1 and Figure 2The hollow inner cavity 610 may have a positioning step surface 612 on its cavity wall, and the side wall of the fixed plate away from the movable plate is flush with the positioning step surface 612; the atomizer also includes a liquid guide tube 433 that constitutes part of the liquid passage 200, the liquid guide tube 433 has an insertion end that is inserted into the hollow inner cavity 610, and a fixing ring 620 is clamped between the insertion end and the positioning step surface 612.

[0079] For example, the liquid guide tube 433 is a straight tube. One end of the liquid guide tube 433 is located in the buffer cavity 430 and abuts against the cavity wall of the buffer cavity 430, while the other end is inserted into the hollow inner cavity 610 and abuts against the fixing ring 620 coaxially, limiting the fixing ring 620. The liquid guide tube 433 and the hollow inner cavity 610 together form a liquid passage 200. The side wall of the liquid guide tube 433 located in the buffer cavity 430 is provided with a liquid outlet, and the liquid storage port is covered by a liquid storage component 432, so that the liquid aerosol matrix can be discharged from the liquid outlet through the liquid passage 200, and after being absorbed by the liquid storage component 432, it is supplied to the atomizing tube 431.

[0080] In one embodiment, please refer to Figure 1 The atomizer also includes an airflow sensor 700 for detecting the suction intensity. The airflow sensor 700 is electrically connected to the vibration component 330, which has a variable vibration amplitude. The vibration amplitude of the vibration component 330 can be configured to be positively correlated with the suction intensity detected by the airflow sensor 700, so that the atomizer can automatically discharge liquid according to the suction action and adjust the discharge speed without the user having to perform any additional operation. This not only helps to reduce the user's operating burden, but also reduces the risk of dry burning caused by failure to control the discharge in a timely and accurate manner.

[0081] For example, the airflow sensor 700 can be set at the air inlet end of the atomizing tube 431 so that when the suction action occurs, the airflow sensor 700 can detect the suction intensity in time, thereby linking the vibration component 330 to work to drain the liquid. When the suction intensity is increased, the liquid drainage speed is also accelerated to ensure sufficient liquid supply and reduce the risk of dry burning.

[0082] Examples of electronic atomizing devices in this application:

[0083] In one embodiment, please refer to Figures 1-4 The electronic atomizing device includes a device housing 800, a power supply component 900, and an atomizer according to any of the above embodiments. The atomizer is disposed in the device housing 800 and may be at least partially disposed in the device housing 800. The power supply component 900 is used to supply power to the atomizer and may also be disposed in the device housing 800.

[0084] The power supply component 900 can be understood as a collection of circuit boards, battery cells, and other related components. It primarily supports all or some functions of the atomizing device, such as: controlling the start and stop of the vibrator 331, adjusting the vibration amplitude and frequency of the vibrator 331, controlling the start and stop of heating of the atomizing core in the atomizing tube 431, adjusting the heating power of the atomizing core, supplying power to the airflow sensor 700, and displaying the status information of the atomizing device. The power supply component 900 can also be housed within a receiving cavity to supply power to the atomizer.

[0085] The power supply component 900 and the atomizer can be either fixedly connected or detachably connected. When the atomizer and the power supply component 900 are detachably connected, the atomizer and the power supply component 900 can be replaced depending on the usage.

[0086] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
