[0002] Cotton-core electronic vaporizers typically wrap the heating wire with an integrated oil reservoir. During assembly, the matrix is injected into the reservoir for storage. During use, the heating wire heats up and contacts the reservoir, atomizing the matrix. Long-term matrix precipitation within the reservoir leads to uneven matrix distribution. This can lead to poor matrix transfer during use, causing dry burning, burnt wicks, and flavor loss, negatively impacting the user experience. Therefore, improving the uniformity of matrix distribution during electronic vaporizer use has become a pressing technical challenge. Summary of the Invention

[0005] The present application also provides a method for controlling an electronic atomizer, the method comprising:

[0006] The microphone senses the airflow changes in the electronic atomizer;

[0007] The microphone controls the atomizing component to heat the substrate and controls the motor to vibrate synchronously, so that the substrate moves and diffuses under the dual effects of heating and vibration.

[0018] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute a separate or alternative embodiment that is mutually exclusive of other embodiments.

[0019] This application provides an electronic atomizer. Please also refer to Figures 1 to 3 The electronic atomizer 100 may include a housing 10, and housed within the housing 10 are a battery 20, a motor 30, an atomizer assembly 40, and a microphone 50. The atomizer assembly 40 stores a substrate, and one end of the atomizer assembly 40 abuts the motor 30. The battery 20 provides power for the electronic atomizer 100, and the microphone 50 controls the operation of the electronic atomizer 100 by sensing changes in airflow. The motor 30 is used to vibrate the atomizer assembly 40, causing the substrate within the atomizer assembly 40 to move and diffuse. The atomizer assembly 40 can also heat the substrate to atomize it and generate an aerosol.

[0020] The electronic atomizer 100 provided in the present application is provided with a motor 30 that is in contact with the atomizer assembly 40. The motor 30 drives the atomizer assembly 40 to vibrate, so that the matrix in the atomizer assembly 40 is forced to vibrate and diffuse. This can not only accelerate the matrix transfer speed during the atomization process, but also reduce the local deposition of the matrix, thereby improving the uniformity of the matrix distribution in the atomizer assembly 40, reducing product risks such as dry burning, core burn, and flavor attenuation, and improving user experience.

[0021] The electronic atomizer 100 may also include a base 60 and a nozzle 70. The base 60 is installed with an interference fit at one end of the housing 10, and the nozzle 70 is connected to the opposite end of the housing 10, away from the base 60. The microphone 50 and the battery 20 are sequentially installed within the base 60. When a user inhales through the nozzle 70, the microphone 50 detects changes in the internal airflow and controls the battery 20 to power the motor 30 and atomizer assembly 40. The motor 30 drives the atomizer assembly 40 to vibrate, improving the uniformity of the substrate distribution within the atomizer assembly 40. The atomizer assembly 40 heats the substrate to generate an aerosol, which reaches the inhalation end.

[0022] The atomizer assembly 40 includes an atomizer core 41, an oil tank 42, and an oil reservoir 43. During assembly, the substrate is injected into the oil reservoir 43 for storage. The oil reservoir 43 wraps around the atomizer core 41, and the oil reservoir 43 and atomizer core 41 are housed within the oil tank 42. The atomizer core 41 heats the substrate to generate an aerosol.

[0023] The oil tank 42 is provided with an upper oil tank cover 421 and a lower oil tank cover 422. The upper oil tank cover 421 and the lower oil tank cover 422 are located at opposite ends of the oil tank 42. The oil tank 42, the upper oil tank cover 421, and the lower oil tank cover 422 enclose a storage space, and the oil storage cotton 43 and the atomizer core 41 are accommodated in the storage space. The oil tank 42 can be made of PET (polyethylene terephthalate) or PC (polycarbonate). The upper oil tank cover 421 and the lower oil tank cover 422 can be made of silicone. The oil storage cotton 43 can be made of porous PA6 (polyamide 6) or PET fiber, or PP (polypropylene) or PE (polyethylene) fiber.

[0024] The atomizer core 41 is equipped with a heating element 411 and an oil guide 412, which wraps around the outer periphery of the heating element 411. The heating element 411 can be a filamentary or mesh-shaped resistance wire. When powered, the heating element generates heat to heat the substrate. The oil guide 412 can be an oil-conducting cotton pad, which is used to absorb the substrate to the outer periphery of the heating element 411.

[0025] The vibration direction of the motor 30 may be the longitudinal direction of the electronic atomizer 100 , that is, the motor 30 may vibrate along the longitudinal direction of the electronic atomizer 100 , providing a vibration source along the longitudinal direction.

[0026] In one embodiment, the vibration frequency of the motor 30 is 100-1000 Hz, and the amplitude is 0.01-0.5 mm. Specifically, the vibration frequency can be 100 Hz, 200 Hz, 300 Hz, 400 Hz, 500 Hz, 600 Hz, 700 Hz, 800 Hz, 900 Hz, 1000 Hz, etc.; the amplitude can be 0.01 mm, 0.05 mm, 0.1 mm, 0.15 mm, 0.2 mm, 0.25 mm, 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, etc., without specific limitation herein. When the vibration frequency and amplitude of the motor 30 are within the above ranges, the matrix in the atomizing assembly 40 can be fully diffused, thereby improving the uniformity of the matrix distribution.

[0027] To prevent the motor 30 from affecting the contact stability of the wires connected to the battery 20 when in operation, a first vibration isolation member 80 can be provided between the motor 30 and the battery 20. The first vibration isolation member 80 can be made of a flexible material such as silicone, TPE (thermoplastic elastomer), or TPR (thermoplastic rubber). Silicone, TPE, and TPR have excellent weather resistance, fatigue resistance, and temperature resistance, and possess high resilience. They can deform significantly when subjected to force, thus acting as a buffer. This can attenuate the vibration generated by the motor 30, reduce the transmission of vibration, and prevent the motor 30 from affecting the contact stability of the wires connected to the battery 20 when in operation.

[0028] In one embodiment, a second vibration isolation member 90 is provided at the end of the atomizer assembly 40 away from the motor 30. The second vibration isolation member 90 abuts against the oil tank cover 421. The second vibration isolation member 90 can be made of a flexible material such as silicone, TPE, or TPR. These materials have good elasticity, preventing vibrations from the atomizer assembly 40 from being transmitted outward, thereby reducing the impact of vibrations on the inhalation end.

[0029] Since the vibration direction of the motor 30 is along the longitudinal direction of the electronic atomizer 100, it is beneficial to set a first vibration isolation member 80 and a second vibration isolation member 90 at both ends of the atomization assembly 40 to reduce the impact of vibration on other components and prevent the vibration from being transmitted outward and affecting the reliability of the electronic atomizer 100 or user experience.

[0030] The atomizer assembly 40 and the motor 30 can be independently controlled. Specifically, independent control elements are provided to control the atomizer assembly 40 and the motor 30 respectively, such as controlling the atomizer assembly 40 through the microphone 50 and controlling the motor 30 through other circuit boards, and the two are independent of each other. Before use, the user can turn on the motor 30 to vibrate the matrix to improve the uniformity of the matrix distribution in the atomizer assembly 40, and avoid dry burning, burnt core or taste attenuation caused by matrix deposition. It is also possible to turn on the motor 30 to vibrate the matrix when the user feels that the taste has faded, to improve the uniformity of the matrix distribution in the atomizer assembly 40 and enhance the taste experience.

[0031] The atomizer assembly 40 and motor 30 can also be controlled synchronously. In one embodiment, both the atomizer assembly 40 and the motor 30 are electrically connected to a microphone 50. The microphone 50 controls the heating of the substrate by the atomizer assembly 40 by sensing changes in airflow, and controls the synchronous vibration of the motor 30, thereby causing the substrate to move and diffuse under the dual effects of heating and vibration. On the one hand, heating the substrate by the atomizer assembly 40 increases its fluidity, and the forced vibration of the fluid substrate accelerates its movement and diffusion. On the other hand, the synchronous control of the atomizer assembly 40 and the motor 30 by the microphone 50 reduces the number of control components and simplifies the control process compared to independent control of the two.

[0032] The oil tank upper cover 421 is provided with an upper cover air outlet 4211 , and the aerosol formed by atomization of the atomization assembly 40 can reach the user's inhalation end through the upper cover air outlet 4211 and the second shock isolator 90 .

[0033] In order to allow external air to enter the atomizer assembly 40 through the base 60, the bottom of the base 60 is provided with a base air inlet hole 61 and a base transverse air inlet groove 62 that are interconnected. The side wall of the base is provided with a base longitudinal air inlet groove 63, which is connected to the base transverse air inlet groove 62. There can be multiple base transverse air inlet grooves 62, for example, four base transverse air inlet grooves 62 can be provided. Figure 4 As shown, four base transverse air inlet slots 62 are evenly distributed on the bottom of the base 60 to form a cross-shaped air inlet channel. The microphone 50 is installed at the base air inlet hole 61 of the base 60 so that the microphone 50 can sense the airflow changes generated by the user's inhalation.

[0034] External air flows into the motor 30 through the longitudinal air inlet slots 63 of the base. To ensure smooth airflow through the motor 30, the horizontal projection of the motor 30's outer contour is positioned within the horizontal projection of the sidewalls of the base 60. This arrangement, on the one hand, allows the outer contour of the motor 30 to be retracted inward, allowing airflow to flow smoothly through the gap between the motor 30 and the inner wall of the housing 10. On the other hand, the outer contour of the motor 30 is larger than the inner wall of the sidewalls of the base 60, allowing the motor 30 to abut against the end of the base 60 without falling into the base 60.

[0035] The external air flowing through the motor 30 further flows to the oil tank 42. The oil tank lower cover 422 is provided with a lower cover transverse air inlet groove 4221 and a lower cover air inlet hole 4222 that are interconnected. There can be multiple lower cover transverse air inlet grooves 4221, for example, four lower cover transverse air inlet grooves 4221 can be provided. Figure 5 As shown, the four lower cover transverse air intake grooves 4221 are evenly distributed on the oil tank lower cover 422 to form a cross-shaped air intake channel.

[0036] External air can flow through the base air inlet hole 61, the base transverse air inlet groove 62, the base longitudinal air inlet groove 63, the gap between the motor 30 and the inner wall of the shell 10, the lower cover transverse air inlet groove 4221 and the lower cover air inlet hole 4222 in sequence, thereby connecting the atomization assembly 40 with the external air.

[0037] This application provides a control method for an electronic atomizer, which can be used to control the electronic atomizer 100 as described above. Figure 6 , Figure 6 This is a flow chart of an embodiment of the control method of the electronic atomizer provided by the present application. The control method 200 of the electronic atomizer includes steps S210 to S220:

[0038] S210, the microphone 50 senses the change in airflow in the electronic atomizer 100;

[0039] S220, the microphone 50 controls the atomizing assembly 40 to heat the substrate, and controls the motor 30 to vibrate synchronously, so that the substrate moves and diffuses under the dual effects of heating and vibration.

[0040] The control method 200 of the electronic atomizer provided in the present application can, on the one hand, accelerate the movement and diffusion speed of the matrix, and on the other hand, simplify the control procedure.

[0041] The electronic atomizer provided in this application has at least the following beneficial effects:

[0042] 1. By setting a motor 30 in contact with the atomizer assembly 40, the motor 30 drives the atomizer assembly 40 to vibrate, so that the matrix in the atomizer assembly 40 is forced to vibrate and diffuse, which can not only accelerate the matrix transfer speed during the atomization process, but also reduce the local deposition of the matrix, thereby improving the uniformity of the matrix distribution in the atomizer assembly 40.

[0043] 2. The vibration direction of the motor 30 is along the longitudinal direction of the electronic atomizer 100 , which is beneficial for arranging the first vibration isolation member 80 and the second vibration isolation member 90 at both ends of the atomization assembly 40 to reduce the impact of the vibration on other components.

[0044] 3. A first shock isolator 80 is provided between the motor 30 and the battery 20 to act as a buffer to prevent the motor 30 from affecting the contact stability of the wire connected to the battery 20 when the motor 30 is working.

[0045] 4. A second vibration isolation member 90 is provided at one end of the atomizing assembly 40 away from the motor 30 to prevent the vibration of the atomizing assembly 40 from being transmitted outward, thereby reducing the impact of the vibration on the inhalation end.

[0046] 5. The atomizing assembly 40 and the motor 30 are both electrically connected to the microphone 50. The microphone 50 controls the heating of the substrate by the atomizing assembly 40 by sensing the change of the airflow, and controls the synchronous vibration of the motor 30. On the one hand, it can accelerate the movement and diffusion speed of the substrate, and on the other hand, it reduces the number of control components and simplifies the control program.
