Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and in particular to an electronic cigarette that improves the utilization rate of e-liquid. Background Technology

[0002] Electronic cigarettes heat e-liquid into vapor using an atomizing core for inhalation. During inhalation, the aerosol formed by the e-liquid within the atomizing chamber cannot be fully expelled from the airway, leaving some aerosol residue after inhalation. This residue condenses back into e-liquid, resulting in waste. Furthermore, the e-liquid is stored in the e-cigarette's reservoir, which has a limited capacity, leading to low e-liquid utilization and impacting the cost-effectiveness of electronic cigarettes.

[0003] To improve the utilization rate of e-liquid, the amount of e-liquid atomized can be controlled, but this will affect the taste of e-cigarette inhalation. In addition, most existing e-cigarettes reduce the residual aerosol in the atomization chamber by optimizing the structure of the airway, but the effect is not ideal. Utility Model Content

[0031] The specific embodiments of this utility model are described with reference to the accompanying drawings.

[0032] refer to Figure 1 The figure shows a three-dimensional structural diagram of an electronic cigarette that improves the utilization rate of e-liquid. The cartridge part of the electronic cigarette is shown (the main body part of the electronic cigarette is not shown). The overall shape is a cuboid. The mouthpiece 104 protrudes outward from the upper side. An air inlet 31, a magnet 36 and an electrode 34 are provided on the end face of the base 3.

[0033] refer to Figures 1 to 6 An electronic cigarette that improves e-liquid utilization includes an air intake duct 101 leading to an atomizing chamber 102. The air intake duct 101 includes an air intake port 31, a pressurizing chamber 61, and a Laval nozzle 7. The air intake port 31 is located at the bottom of the outer shell. The air intake port 31 has multiple micro-holes 32 on the side of the pressurizing chamber 61. The micro-holes 32 connect the air intake port 31 and the pressurizing chamber 61. The constriction section 71 of the Laval nozzle 7 is connected to the pressurizing chamber 61. The expansion section 72 of the Laval nozzle 7 is positioned toward the atomizing core 1 of the atomizing chamber 102.

[0034] The electronic cigarette of this application that improves the utilization rate of e-liquid utilizes the Laval effect in the air intake duct 101 to accelerate the airflow, so that the Laval nozzle 7 can spray a faster airflow into the atomizing chamber 102, which fully carries out the aerosol in the atomizing chamber 102, reduces the amount of residual aerosol in the atomizing chamber 102, avoids excessive e-liquid condensation in the atomizing chamber 102, and improves the utilization rate of e-liquid; the air intake port 31 introduces air through multiple micro-holes 32, increases the speed of the airflow entering the pressurization chamber 61, and increases the air pressure in the pressurization chamber 61.

[0035] In order to install the atomizer core 1, in this embodiment, refer to Figures 2 to 6 The e-cigarette that improves the utilization rate of e-liquid also includes an oil cup 2, a base 3, and a bracket 4. The oil cup 2 is snapped into the base 3. The atomizing core 1 is installed inside the oil cup 2 through the bracket 4. An oil-sealing silicone 5 is provided between the oil cup 2 and the bracket 4. An oil cavity 21 is formed between the oil-sealing silicone 5 and the inner wall of the oil cup 2. The atomizing cavity 102 is provided between the bracket 4 and the base 3. An air outlet 103 is provided between the mouthpiece 104 of the oil cup 2 and the atomizing cavity 102.

[0036] Understandably, with this setup, the oil chamber 21 is used to hold e-liquid, and the oil chamber 21 is sealed by the sealing silicone 5 to prevent oil leakage. The atomizing core 1 is installed inside the oil cup 2 through the bracket 4. The air intake 101, the atomizing chamber 102 and the air outlet 103 are connected to form the air passage for drawing e-liquid.

[0037] In order to configure the Laval nozzle 7, in this embodiment, refer to Figures 2 to 5 The base 3 is provided with an airway silicone 6, the Laval nozzle 7 is provided on the airway silicone 6, the outer wall of the airway silicone 6 is provided with a protrusion 62 that is in sealing contact with the inner wall of the base 3, a pressurization chamber 61 is formed between the airway silicone 6 and the inner wall of the base 3, and the air inlet 31 is provided on the end face of the base 3.

[0038] Understandably, with this configuration, the Laval nozzle 7 is integrally molded onto the airway silicone 6, and the airway silicone 6 is sealed to the inner wall of the base 3 by the protrusion 62, so that the pressurization chamber 61 has good airtightness and ensures that the Laval nozzle 7 can accelerate the airflow well.

[0039] In order to seal the space between the base 3 and the oil cup 2, in this embodiment, reference is made to... Figures 2 to 4 A sealing ring 33 is provided between the outer wall of the base 3 and the inner wall of the oil cup 2.

[0040] Understandably, with this configuration, the sealing ring 33 is an O-ring, which seals the gap between the outer wall of the base 3 and the inner wall of the oil cup 2, ensuring the airtightness of the internal air passage.

[0041] To avoid oil leakage, in this embodiment, reference is made to Figures 2 to 4 Oil-absorbing cotton 8 is provided between the airway silicone 6 and the bracket 4 and inside the pressurization chamber 61.

[0042] Understandably, with this setup, the aerosol remaining in the atomizing chamber 102 during inhalation will condense into e-liquid droplets. Furthermore, the remaining aerosol diffuses into the pressurizing chamber 61 under molecular action. The oil-absorbing cotton 8 between the airway silicone 6 and the support 4 absorbs the condensed e-liquid in the atomizing chamber 102, and the oil-absorbing cotton 8 in the pressurizing chamber 61 absorbs the condensed e-liquid, thus preventing e-liquid from leaking to the outside.

[0043] To better remove the aerosol from the atomizing chamber 102, in this embodiment, reference is made to... Figures 2 to 5 The bracket 4 is provided with a mounting groove 41, an oil inlet 42 and a Y-shaped air outlet channel 43. The atomizing core 1 is fixed in the mounting groove 41. The oil inlet 42 is connected to the oil chamber 21 and the mounting groove 41 to guide the e-liquid in the oil chamber 21 to penetrate into the atomizing core 1. The Y-shaped air outlet channel 43 is connected to the air outlet channel 103 and the atomizing chamber 102 to guide the airflow in the atomizing chamber 102 to mix and be transported to the air outlet channel 103.

[0044] It should be further explained that the atomizing core 1 is a ceramic atomizing core 1, which is fitted with a silicone sleeve. The ceramic atomizing core 1 is sealed to the inner wall of the mounting groove 41 through the silicone sleeve, so that the e-liquid in the oil chamber 21 only permeates into the ceramic atomizing core 1 through the oil inlet 42, thus avoiding oil leakage at the mounting groove 41.

[0045] Understandably, with this setup, the atomizing core 1 atomizes the e-liquid into an aerosol, which diffuses into the atomizing chamber 102. The Laval nozzle 7 sprays airflow into the atomizing chamber 102. After carrying the aerosol, the airflow in the atomizing chamber 102 splits into two streams that enter the Y-shaped air outlet channel 43 from both sides. At the intersection of the Y-shaped air outlet channel 43, the two streams collide before entering the air outlet channel 103. The collision process can accelerate the mixing of the aerosol and air, improve the taste, and finally be inhaled by people through the mouthpiece 104.

[0046] To ensure that the e-liquid in the oil cup 2 can stably penetrate into the atomizer core 1, in this embodiment, reference is made to... Figure 3 The bracket 4 is provided with two oil inlet holes 42, which are arranged in a V-shape.

[0047] Understandably, this design increases the amount of e-liquid that penetrates the atomizer core 1 into the oil chamber 21 through the two oil inlet holes 42, thus preventing the atomizer core 1 from burning due to dry burning.

[0048] In order to power the atomizer core 1, in this embodiment, reference is made to Figures 2 to 6 An electrode 34 is provided on the base 3 towards the atomizing core 1. The electrode 34 is electrically connected to the atomizing core 1, and the conductive surface 35 of the electrode 34 is exposed on the end face of the base 3.

[0049] Understandably, with this configuration, the conductive surface 35 of electrode 34 contacts and conducts with the spring pin of the main unit, and the current of the main unit flows to the atomizing core 1 through electrode 34. The increased conductive surface 35 of electrode 34 ensures the contact area between electrode 34 and spring pin.

[0050] For ease of connection with the host, in this embodiment, reference is made to... Figures 1 to 2 A magnet 36 is fixed on the end face of the base 3.

[0051] Understandably, with this setup, two magnets 36 are installed on the base 3, and the base 3 is magnetically fixed to the main unit through the magnets 36, making it convenient for the e-cigarette cartridge to connect with the main unit.

[0052] To achieve the Laval effect, in this embodiment, reference is made to... Figure 3 and Figure 4 The contraction section 71 is a hemispherical cavity, and the expansion section 72 is a trumpet-shaped cavity.

[0053] Understandably, with this configuration, there is a narrow throat 73 between the contraction section 71 and the expansion section 72 of the Laval nozzle 7. The hemispherical cavity can effectively contract the airflow and compress it to the narrow throat 73. The trumpet-shaped cavity can guide the airflow to expand, creating a negative pressure relative to the narrow throat 73, attracting the airflow at the narrow throat 73, increasing the airflow velocity, and forming the Laval effect.

[0054] The electronic cigarette of this application that improves e-liquid utilization integrates the Laval nozzle 7 into the airway silicone 6. The airway silicone 6 and the base 3 form a pressurization chamber 61. Air is introduced through multiple micro-holes 32 of the air inlet 31, increasing the speed of the airflow into the pressurization chamber 61 and increasing the air pressure in the pressurization chamber 61. The airflow in the pressurization chamber 61 is accelerated by the Laval nozzle 7, so that the Laval nozzle 7 can spray a faster airflow into the atomization chamber 102, fully carrying out the aerosol in the atomization chamber 102, reducing the amount of residual aerosol in the atomization chamber 102, avoiding excessive e-liquid condensation in the atomization chamber 102, and improving e-liquid utilization.

[0055] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
