[0002] Electronic atomization devices in related technologies primarily employ electric heating to atomize a liquid aerosol generating matrix for inhalation. For example, porous media such as porous ceramics or porous cotton are combined with resistance wires or films and heated to form an aerosol. However, when using electric heating for atomization, the high temperature can easily cause the liquid aerosol generating matrix to decompose and denature on the resistance wire or film, affecting the taste. Furthermore, once the liquid aerosol generating matrix is ​​depleted, the resistance wire or film may burn dry, potentially producing harmful substances and posing safety hazards.

Detailed Implementation

[0024] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0025] Figure 1 and Figure 2An electronic atomizing device according to some embodiments of the present invention is shown. The electronic atomizing device 1 is generally elongated in shape with a circular cross-section. It is used to atomize a liquid aerosol generating matrix, such as e-liquid or liquid medicine, into an aerosol for inhalation by a user. It may include an atomizer 10 and a main unit 20. The atomizer 10 is detachably inserted into the main unit 20 along the longitudinal direction of the electronic atomizing device 1 and is electrically connected to the main unit. It is used to contain the liquid aerosol generating matrix and to atomize the aerosol generating matrix. The main unit 20 is used to power the atomizer 10 and to control the operation of the entire electronic atomizing device 1. Understandably, in some embodiments, the atomizer 10 may be a disposable atomizer 10, which can be replaced with a new atomizer 10 when the liquid aerosol generating matrix inside is consumed.

[0026] like Figures 3 to 6 As shown, in some embodiments, the atomizer 10 may include a housing 11, a connecting assembly 12, a support assembly 13, a temperature sensor 14, an atomizer bottom shell 15, and an atomizing nozzle 16. The housing 11 is located outside the atomizer 10, forming the main structure of the atomizer 10. Its lower end is connected to the atomizer bottom shell 15 and can be used to house the support assembly 13, the connecting assembly 12, etc. The support assembly 13 is connected to the housing 11 via the connecting assembly 12 and can be used to support the various functional components of the atomizer 10. The temperature sensor 14 is connected to the support assembly 13 and can be used to detect the internal temperature of the atomizer 10, thereby enabling the electronic atomizing device 1 to make corresponding adjustments to achieve stable atomization volume. The atomizer bottom shell 15 is connected to the lower end of the housing 11 and can be used to house the various components of the electronic atomizing device 1. The atomizing nozzle 16 is connected to the support assembly 13 and is in communication with the external air guide of the housing 11. It can be used to atomize liquid aerosol generating matrix.

[0027] In some embodiments, the housing 11 may include a mouthpiece hole 111, an air outlet channel 113, and a liquid storage chamber 112. The mouthpiece hole 111 is formed at the top of the housing 11, allowing the user to inhale the aerosol generated by the atomizer 10. The air outlet channel 113 is located below the mouthpiece hole 111 and extends downwards into the interior of the housing 11, allowing the aerosol to be transported through the air outlet channel 113 and inhaled by the user via the mouthpiece hole 111. The liquid storage chamber 112 is a closed space formed by the housing 11 and the support assembly 13, and can be used to contain the liquid aerosol generation matrix.

[0028] In some embodiments, the connecting assembly 12 may include a support 121, a heating element 122, an electrode 124, and a sealing gasket 123. The support 121 is a hollow tube connected to the upper end of the heating element 122 and embedded in the housing 11. It supports the heating element 122. The atomized aerosol, after condensation, is contained in the support 121 and can flow back to the heating element 122 for re-atomization, ensuring that the aerosol inhaled by the user does not have excessively large droplets, thus improving the user experience. The heating element 122 has a hollow structure and is mounted on the bracket assembly 13. It is used to further atomize the aerosol generated by the atomizing nozzle 16, thereby optimizing the atomization effect of the atomizer 10. The electrode 124 is mounted on the bracket assembly 13 and is used to electrically connect the atomizer 10 to the main unit 20 and to supply power to the atomizer 10. There can be three electrodes. The sealing gasket 123 can be made of a soft silicone material, is ring-shaped, and is installed on the bracket assembly 13. It can be used to seal the bracket assembly 13 to obtain good airtightness and prevent leakage of the liquid aerosol generation matrix, thereby ensuring the normal operation of other components, such as the temperature sensor 14.

[0029] In some embodiments, the heating element 122 may further include a heating body (not numbered) and two electrical wires 1221. The heating body is tubular and may be made of a material with good thermal conductivity, such as ceramic. It can be used to heat the aerosol sprayed from the atomizing nozzle 16 to further atomize the aerosol and achieve a better atomization effect. The electrical wires 1221 are connected to the heating body and can be used to transmit electrical energy to the heating element 122. There are two electrical wires 1221, which are respectively connected to two opposite sides of the heating body. They can be used to electrically connect the heating element 122 to the host 20 to realize the heating function of the heating element 122.

[0030] In some embodiments, the support assembly 13 may include a sealing cap 131, a support 132, and a base 133. The sealing cap 131, in some embodiments, may be made of silicone and is generally circular. Its upper end is connected to the housing 11, forming a liquid storage chamber 112, and its lower end is connected to the support 132, allowing the liquid aerosol generation matrix to be introduced into the atomizing nozzle 16. The support 132 has the same shape as the sealing cap 131 and is mounted on the base 133. It supports the sealing cap 131 and other components of the atomizer 10 and also stores a portion of the aerosol generation matrix. The base 133 is located at the lower part of the atomizer 10, with a sealing gasket 123 connected to its upper end and connected to the support 132. Specifically, the sealing gasket 123 is sandwiched between the base 133 and the support 132, effectively preventing leakage of the liquid aerosol generation matrix. The space formed by the base 133 and the support 132 can be used to accommodate other components of the atomizer 10, such as the temperature sensor 14.

[0031] like Figure 7As shown, in some embodiments, the sealing cap 131 may include a first liquid guide port 1311 and a first receiving cavity 1312. The first liquid guide port 1311 is formed on the top surface of the sealing cap 131 and extends vertically through the top surface. It can be used to guide the liquid aerosol generating matrix in the liquid storage cavity 122 to the atomizing nozzle 16, thereby realizing the atomization function of the atomizer 10. The first receiving cavity 1312 is located at the center of the sealing cap 131 and can be used to receive the atomizing nozzle 16. In some embodiments, the first receiving cavity 1312 may include a second liquid guide port 1313. The second liquid guide port 1313 is disposed on the cavity wall of the first receiving cavity 1312 and can be used to introduce the liquid aerosol generating matrix into the atomizing nozzle 16.

[0032] In some embodiments, the support 132 may include a first air guide hole (not labeled), an electrode receiving groove 1321, and a third liquid guide port 1322. The first air guide hole is formed at the center of the support 132 and can be used to guide gas upward to the atomizing nozzle 16 housed in the sealing cap 131.

[0033] Three electrode receiving slots 1321 are formed on the lower surface of the support 132, which can be used to house three electrodes 124 for conducting electricity. One of the three electrodes 142 is a ground wire, one of the other two electrodes can be connected to the ground wire to supply power to the heating element 122, and the other can be connected to the ground wire to the temperature sensor 14. Two of the three receiving slots are symmetrically arranged on two opposite sides of the support 132, and the position of the third receiving slot is perpendicular to the line connecting the center of the support 132 and the line connecting the two symmetrically arranged receiving slots. The two electrical wires 1221 of the heating element 122 are installed in the receiving slots symmetrically arranged on two opposite sides of the support 132, and are mechanically and electrically connected to the two electrodes 124 installed therein, so that the heating element 122 can conduct electricity for heating.

[0034] The third liquid guide port 1322 is formed on the top surface of the support 132 and extends vertically through the top surface. It is interconnected with the first liquid guide port 1311. The liquid aerosol generating matrix enters the atomizing nozzle 16 from the liquid storage cavity through the first liquid guide port 1311 and the third liquid guide port 1322, and from the second liquid guide port 1313.

[0035] In some embodiments, the base 133 may include a through hole 1331. The through hole 1331 is formed at the lower end of the base 133, and the number of through holes 1331 may be at least 5, which can be used to accommodate the electrode 124, conduct gas, etc.

[0036] like Figure 9 , Figure 10As shown, in some embodiments, the atomizing nozzle 16 may include an airflow channel 161, a liquid inlet channel 162, and an atomizing chamber 163. The airflow channel 161 is arranged longitudinally along the electronic atomizing device 1 and can be used to transmit the airflow provided by the host 20. The liquid inlet channel 162 is arranged transversely, with one end connected to the second liquid guide port 1313 and the other end located on one side of the airflow channel 161 and communicating with the atomizing chamber 163. It can be used to transmit the liquid aerosol generating matrix into the atomizing chamber 163. The atomizing chamber 163 is connected to both the airflow channel 161 and the liquid inlet channel 162, and can be used to atomize the liquid aerosol generating matrix in a non-phase-change manner.

[0037] In some embodiments, the airflow channel 161 may include a connecting channel 1612 and a constricting channel 1611. The connecting channel 1612 has a longitudinally elongated rectangular cross-section, is located below the constricting channel 1611, and communicates with it. It can be used to connect the first air guide hole of the support 132, thereby guiding the airflow into the atomizing chamber 163. The constricting channel 1611 has a trapezoidal cross-section with the upper base smaller than the lower base, which can be used to increase the airflow velocity, thereby enabling the liquid aerosol generating matrix to have a better atomization effect in the atomizing nozzle 16. In some embodiments, the airflow channel opening 1613 is located on the bottom surface of the atomizing chamber 163, so that atomization occurs at the point of maximum airflow.

[0038] In some embodiments, the liquid inlet channel 162 may include a liquid inlet front section 1621, a liquid inlet end section 1622, and a liquid inlet 1620. One end of the liquid inlet front section 1621 is connected to a second liquid guide port, and the other end is connected to one end of the liquid inlet end section 1622, which can be used to introduce the liquid aerosol generating matrix in the liquid storage chamber 112 into the atomizing chamber 163. The liquid inlet end section 1622 has a trapezoidal cross-section, and its other end is connected to the atomizing chamber 163 and is perpendicular to the axis of the airflow channel 161. It can be used to introduce the liquid aerosol generating matrix into the atomizing chamber 163. The liquid inlet 1620 is located at the junction of the liquid inlet end section 1622 and the side of the atomizing chamber 163, and the liquid aerosol generating matrix flows into the atomizing chamber 163 through the liquid inlet 1620.

[0039] In some embodiments, the atomizing chamber 163 has a generally rectangular cross-section, including a first atomizing point 1631, a second atomizing point 1632, and a spray outlet 1633. The first atomizing point 1631 is formed on the bottom surface of the atomizing chamber 163 near the airflow channel opening 1613. The liquid aerosol generating matrix enters through the liquid inlet 1620 and flows to the airflow channel opening 1613, where the airflow cuts the liquid aerosol generating matrix into large droplets. Understandably, due to the small size of the airflow channel opening 1613, the liquid aerosol generating matrix, due to its viscosity, usually does not fall into the airflow channel.

[0040] The cross-section of the spray outlet 1633 is a trapezoid with the upper base larger than the lower base. It is formed at the top of the atomizing chamber 163. The atomized aerosol is discharged upward through the spray outlet 1633 for the user to inhale.

[0041] Figure 11 This is a schematic longitudinal cross-sectional view of the atomizing nozzle 16 in the prior art. Figure 12 This is a longitudinal cross-sectional schematic diagram of the atomizing nozzle 16 in some embodiments of the present invention, such as... Figure 11 as well as Figure 12 As shown, in Figure 11 The distance between the outlet of the liquid inlet channel and the axis of the airflow channel opening is greater than half the width of the airflow channel opening. Figure 12 The distance between the outlet of the liquid inlet channel and the axis of the airflow channel opening is no greater than half the width of the airflow channel opening. It can be understood that, in this embodiment, the width of the airflow channel refers to the horizontal distance of the airflow channel along the plane of the paper in the figure. Figure 12 The second atomizing point 1632 is formed on the side of the atomizing chamber 163 near the upper end of the liquid inlet 1620 (i.e., the end of the liquid inlet channel away from the airflow channel). Large droplets, after being cut, are further cut by the second atomizing point 1632 to form smaller sizes, thus achieving a better atomization effect. The specific atomization effects are shown in the table below, where Z represents the atomizing nozzle 16 of this invention, and Z1 represents the atomizing nozzle 16 in the prior art, with the following atomization parameters. Because this invention performs further cutting at the second atomizing point 1632, the maximum particle radius (Dmax) significantly decreases from 220 μm in the prior art to 120 μm; the particle radius (D90) significantly decreases from 90.8 μm in the prior art to 53.8 μm; and the particle radius (D50) significantly decreases from 35.0 μm in the prior art to 22.2 μm. These differences indicate that using the atomizing nozzle 16 of this invention can achieve a more ideal atomization effect.

[0042] In some embodiments, the airflow channel opening 1613 is not located at the center of the bottom surface of the atomizing chamber 163, that is, the atomizing chamber 163 and the airflow channel 161 are designed asymmetrically, thereby increasing the relative velocity between the airflow and the liquid aerosol generating matrix, resulting in better atomization. Specifically, this asymmetrical design can be such that the distance between one side of the liquid inlet 1620 of the atomizing chamber 163 and the axis of the airflow channel 161 is less than the distance between the other side of the atomizing chamber 163 and the axis of the airflow channel 161.

[0043] All features of the airflow channel 161 and the liquid inlet channel 162 have the same thickness δ. In some embodiments, the thickness δ of the airflow channel 161 and the liquid inlet channel 162 can be 0.15 mm to 0.25 mm. By ensuring the dimensions of the airflow channel 161 and controlling the gas-liquid shear rate, the atomization effect and air volume can be controlled.

[0044] The width of the atomizing chamber 163 is related to the magnitude of the negative pressure generated within it. In some embodiments, the width of the atomizing chamber 163 can range from 0.5 mm to 1.4 mm. The width of the connecting channel 1612 is related to the magnitude of the air intake resistance. In some embodiments, the width of the connecting channel 1612 can range from 0.8 mm to 2 mm. By controlling the width of the airflow channel opening 1613, the gas-liquid shear rate can be controlled, thereby controlling the atomization effect and air volume. In some embodiments, the width of the airflow channel opening 1613 can range from 0.15 mm to 0.25 mm. The angle of the injection outlet 1633 can be 20° to 80° in some embodiments. The size of the contraction angle formed by the contraction channel 1611 is related to the magnitude of the resistance within the contraction channel 1611. In some embodiments, the contraction angle formed by the contraction channel 1611 can be 20° to 80°. The width of the inlet 1620 can be 0.2mm to 0.4mm, and the extension length of the inlet end section can be greater than or equal to 0.4mm. The capillary force within the inlet end section 1622 can reduce the backflow of the liquid matrix. The height of the atomizing chamber 163 can be 0.6mm to 1.3mm, and the vertical distance between the lower end of the inlet 1620 and the lower end of the atomizing chamber 163 can be 0.2mm to 0.6mm. The height-to-width ratio of the atomizing chamber 163 can be 1 to 1.2 to ensure sufficient negative pressure within the atomizing chamber 163 and to prevent the atomized droplets from hitting the walls.

[0045] The manufacturing process of the atomizing nozzle 16 may include micro-nano fabrication and anodic bonding in some embodiments. The material of the atomizing nozzle 16 may be a silicon wafer and a glass plate in some embodiments; preferably, the silicon wafer may be made of monocrystalline silicon, and the glass plate may be made of alkali metal silicate glass.

[0046] The method for preparing the atomizing nozzle 16 includes the following steps: S1. Clean the substrate thoroughly with organic solvent and pure water; The organic solution can be one or more of solutions such as acetone and isopropanol; the substrate can be made of silicon wafers and glass plates, preferably monocrystalline silicon or alkali metal silicate glass.

[0047] S2. A plurality of regularly arranged nozzle structures are etched on a silicon wafer substrate; The etching methods can include photolithography and dry etching.

[0048] S3. Clean the etched silicon substrate again with organic solvent and pure water; S4. The substrate is sealed by anodic bonding; Specifically, the etched and cleaned silicon wafer substrate and glass substrate are permanently sealed together by anodic bonding to form a complete structure of multiple regularly arranged nozzles; wherein, the sealing can be performed by sandwiching a silicon wafer between two glass substrates.

[0049] S5. Cut and seal a plurality of regularly arranged nozzle structures to obtain a single atomizing nozzle 16.

[0050] One cutting method is the use of a cutting wheel.

[0051] like Figure 8 As shown, in some embodiments, the main unit 20 may include a housing 21, a battery assembly 22, a main control board 23, and a diaphragm pump 24. The housing 21 is made of a rigid material and has a circular cross-section, forming the external main structure of the main unit 20, and can be used for the battery assembly 22 and the main control board 23. The battery assembly 22 can be used to provide the necessary electrical energy for the main unit 20 and the atomizer 10. The main control board 23 is generally plate-shaped, with one side close to and electrically connected to the battery assembly 22. The lower end of the diaphragm pump 24 is electrically connected to the upper end of the battery assembly 22 and can be used to provide a stable airflow for the electronic atomizing device 1.

[0052] Understandably, the above-mentioned technical features can be used in any combination without restriction.

[0053] The above embodiments merely illustrate specific implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can freely combine the above technical features without departing from the concept of the present invention, and can also make several modifications and improvements, all of which fall within the protection scope of the present invention. Therefore, all equivalent transformations and modifications made with respect to the scope of the claims of the present invention should fall within the scope of the claims of the present invention.
