An oil-leak-proof electronic atomizing device

Abstract

This invention relates to a leak-proof electronic atomizing device, comprising a compatible atomizer and a main unit. The atomizer includes a housing, an atomizing component, and a piston assembly. The piston assembly includes a piston and a hollow piston rod, with the hollow piston rod dividing the housing into an oil storage chamber and an atomizing chamber. The piston is fitted onto the hollow piston rod, and the piston divides the atomizing chamber into a liquid chamber and a gas chamber. The hollow piston rod has an oil guide hole, through which the atomizing component in the atomizing chamber communicates with the liquid chamber. As the e-liquid decreases, the main unit controls the piston to move towards the liquid chamber, compressing the e-liquid and expelling air from the liquid chamber through the oil guide hole. During high-temperature storage, this prevents the gas from squeezing out the e-liquid from the oil storage chamber due to the gas's thermal expansion being greater than that of the liquid. During low-pressure transportation, this prevents the gas in the oil storage chamber from squeezing out some e-liquid due to the gas pressure being higher than the external environment, thus achieving a leak-proof function.

Description

Technical Field

[0001] This invention relates to the field of cigarette alternative technology, and in particular to a leak-proof electronic atomizing device. Background Technology

[0002] Electronic atomizing devices are electronic products that mimic cigarettes, producing similar aerosols, flavors, and sensations. Due to their cool appearance, variety of flavors, and ease of use, electronic atomizing devices have been rapidly adopted and promoted.

[0003] Generally, the working principle of e-liquid electronic atomizing devices is as follows: a heating wire heats the e-liquid, and when air is inhaled at the mouthpiece, a pneumatic switch is triggered, which energizes the heating wire and causes the liquid e-liquid to atomize into an aerosol. The aerosol is then carried to the mouthpiece by the airflow for the user to inhale.

[0004] The heating wire used to heat and atomize the e-liquid and the oil suction device that absorbs the e-liquid are usually located at the bottom of the e-liquid storage structure of the atomizer. The oil suction device and the e-liquid storage structure are connected by a through hole that allows the e-liquid to flow. The oil suction device is in a state of saturation with e-liquid for a long time. When the heating wire attached to the oil suction device is energized and heated, the e-liquid absorbed in the oil suction device is atomized at high temperature to form an aerosol for the user to inhale.

[0005] However, when the e-liquid and air inside the oil storage structure are subjected to high temperature or low pressure, the gas expands more than the liquid, making the e-liquid inside the oil storage structure more likely to be squeezed out and leak from the through hole between the oil suction device and the oil storage structure, which can easily lead to oil leakage. Summary of the Invention

[0006] Therefore, it is necessary to provide an oil-proof electronic atomizing device that is less prone to oil leakage under high temperature or low pressure to address the above problems.

[0007] An oil-leakage-proof electronic atomizing device includes an atomizer and a main unit, wherein the atomizer is adapted to the main unit; the atomizer includes a housing, an atomizing component, and a piston assembly; the piston assembly includes a piston and a hollow piston rod, the outer and inner sides of the hollow piston rod dividing the interior of the housing into an oil storage chamber and an atomizing chamber; the piston is sleeved on the hollow piston rod, and the piston divides the oil storage chamber into a liquid chamber and a gas chamber; the hollow piston rod has an oil guide hole connecting the liquid chamber and the atomizing chamber; the atomizing component is disposed in the atomizing chamber, and the atomizing component communicates with the liquid chamber through the oil guide hole; the piston moves according to the gas-liquid changes in the liquid chamber and the gas chamber.

[0008] In one embodiment, the piston assembly further includes a motor electrically connected to the main unit, the hollow piston rod being linked to the motor, and the piston moving as the hollow piston rod rotates.

[0009] In one embodiment, the motor is a geared motor, and the hollow piston rod is linked to the geared motor; the geared motor is electrically connected to the main unit.

[0010] In one embodiment, the rotating shaft of the geared motor is inserted into the hollow piston rod, and the insertion parts of the hollow piston rod and the rotating shaft are both non-circular in shape, and the rotating shaft drives the hollow piston rod to rotate.

[0011] In one embodiment, the piston includes a sealing part and a rotating part. The rotating part is convex and sleeved on the hollow piston rod, and the rotating part meshes with the hollow piston rod gear. The rotating part is embedded in the sealing part, and the sealing part seals the gap between the liquid chamber and the gas chamber.

[0012] In one embodiment, the rotating part is made of a rigid material, the sealing part is made of silicone material, and the rotation of the piston rod drives the rotating part and the sealing part to move from the gas chamber to the liquid chamber.

[0013] In one embodiment, the housing includes an outer shell and a bottom shell. The outer shell includes a nozzle end and an open end, and the bottom shell is inserted into the open end. The hollow piston rod passes through the bottom shell and communicates with the nozzle end. The hollow piston rod divides the internal cavity formed by the outer shell and the bottom shell into an oil storage chamber and an atomizing chamber, and the atomizing chamber is the hollow interior of the hollow piston rod. The atomizing component is disposed in the atomizing chamber.

[0014] In one embodiment, an air intake channel communicating with the outside is provided along the surface of the bottom shell, and an air intake hole is provided radially on the hollow piston rod. The atomizing chamber is connected to the air intake channel through the air intake hole.

[0015] In one embodiment, the oil guide hole and the atomizing component are both located near the nozzle end, and the liquid chamber and the gas chamber are located near the nozzle end and the bottom shell, respectively; a liquid suction element is also provided in the atomizing chamber between the atomizing component and the bottom shell, the liquid suction element is hollow and ring-shaped, and fits against the inner wall of the hollow piston rod.

[0016] In one embodiment, the host is provided with an adjustment knob that adjusts the duty cycle of the motor's rotation time.

[0017] The aforementioned leak-proof electronic atomizing device has at least the following advantages:

[0018] This e-cigarette device features a piston assembly within its e-liquid reservoir, dividing it into a liquid chamber and a gas chamber. As the device draws in, the e-liquid in the liquid chamber decreases. The main unit controls the piston assembly to move towards the liquid chamber as the e-liquid decreases, expelling air from the liquid chamber through the wicking hole. Therefore, in any given state, the liquid chamber contains only e-liquid, and the gas chamber contains only air. When the e-cigarette is stored at high temperatures, this prevents the gas from forcing e-liquid out of the reservoir due to the greater thermal expansion of the gas compared to the liquid. Similarly, when the e-cigarette is transported under low pressure, this prevents the gas from forcing some e-liquid out of the reservoir due to the higher pressure inside the reservoir compared to the external environment. The piston assembly's division of the reservoir into a liquid chamber (containing only e-liquid) and a gas chamber (containing only gas) prevents leakage under both high and low pressure conditions, effectively preventing e-liquid leakage.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] Please see Figure 1 This is a schematic diagram of the structure of an electronic atomizing device for preventing oil leakage in one embodiment.

[0026] The leak-proof electronic atomizing device includes an atomizer 10 and a main unit 20. The atomizer 10 is the aerosol generator of the electronic atomizing device, and the main unit 20 is the control center of the electronic atomizing device. The atomizer 10 is compatible with the main unit 20.

[0027] For details, please refer to Figure 2 , Figure 3 The atomizer 10 includes a housing 12, an atomizing assembly 14, and a piston assembly 16. Both the atomizing assembly 14 and the piston assembly 16 are disposed inside the hollow cavity of the housing 12. The piston assembly 16 includes a piston 162 and a hollow piston rod 164. The exterior and interior of the hollow piston rod 164 divide the hollow cavity of the housing 12 into an oil storage chamber 122 and an atomizing chamber 124. The piston 162 is disposed within the oil storage chamber 122 and is sleeved on... The hollow piston rod 164 and piston 162 divide the oil storage chamber 122 into a liquid chamber 1222 and a gas chamber 1224. The hollow piston rod 164 has an oil guide hole 1642 connecting the liquid chamber 1222 and the atomizing chamber 124. The atomizing component 14 is disposed in the atomizing chamber 124 and is connected to the liquid chamber 1222 via the oil guide hole 1642. The piston 162 moves in accordance with the gas-liquid changes in the liquid chamber 1222 and the gas chamber 1224. Furthermore, the piston 162 moves from the gas chamber 1224 to the liquid chamber 1222 as the e-liquid decreases.

[0028] The electronic atomizing device has a piston assembly 16 inside the oil reservoir 122, which divides the oil reservoir 122 into two chambers: a liquid chamber 1222 and a gas chamber 1224. As the electronic atomizing device draws in, the e-liquid in the liquid chamber 1222 decreases. The main unit 20 controls the piston assembly 16 to move towards the liquid chamber 1222 as the e-liquid decreases. After the e-liquid decreases, the air in the liquid chamber 1222 is discharged through the wicking hole 1642. Thus, in any state, the liquid chamber 1222 contains only e-liquid, and the gas chamber 1224 contains only air. When the electronic atomizing device is stored at high temperatures, it can prevent the gas from squeezing out the e-liquid from the oil reservoir 122 due to the greater thermal expansion of the gas than the liquid. When the electronic atomizing device is transported at low pressure, it can prevent the gas in the oil reservoir 122 from squeezing out some of the e-liquid from the oil reservoir 122 due to the higher air pressure inside the oil reservoir 122 than the external environment. The piston assembly 16 divides the oil storage chamber 122 into two chambers: a liquid chamber 1222 that holds only e-liquid and a gas chamber 1224 that holds only gas. This prevents oil leakage from occurring in the electronic atomizing device under high temperature or low pressure, thus playing a role in preventing oil leakage.

[0029] Please see Figure 2 , Figure 3 In this embodiment, the piston assembly 16 further includes a motor 166, which is electrically connected to the host 20 and is located inside the host 20 to provide power for the movement of the piston assembly 16; the hollow piston rod 164 is linked with the motor 166, and the piston 162 moves with the rotation of the hollow piston rod 164. Specifically, when the e-liquid is stored in the reservoir 122, the e-liquid in the reservoir 122 will continuously decrease as the e-liquid is atomized at high temperature when the user uses the electronic atomizing device. The main unit 20 controls the rotation of the motor 166 by controlling the power on and off of the motor 166, thereby controlling the rotation of the hollow piston rod 164 linked to the motor 166, and further controlling the movement of the piston 162. As the e-liquid decreases, the piston 162 moves towards the liquid chamber 1222, preventing air from entering the liquid chamber 1222 due to the decrease in e-liquid. This avoids the situation where the thermal expansion of the gas is greater than that of the liquid at high temperature, causing the gas to squeeze the e-liquid out of the reservoir 122, and also avoids the situation where the gas in the reservoir 122 squeezes out some of the e-liquid because the air pressure in the reservoir 122 is higher than that of the external environment.

[0030] Furthermore, motor 166 is a geared motor, and the hollow piston rod 164 is linked to the geared motor; the geared motor is electrically connected to the main unit 20. The geared motor is an integrated unit of a reducer and motor 166 (motor), typically using n sets of gears with different numbers of teeth to reduce the output shaft speed of motor 166 to the required speed. The geared motor can be used in conjunction with a rotary encoder. Specifically, because the amount of e-liquid consumed per vaping cycle is very small when using an electronic atomizing device, the required displacement of piston 162 is also very small. Since piston 162 is powered by the rotation of motor 166, the required output rotation of motor 166 is also very small. Therefore, it is preferable that motor 166 is a geared motor, which allows for perfect coordination between motor 166 and the amount of e-liquid consumed when using an electronic atomizing device.

[0031] The rotating shaft 1662 of the geared motor is inserted into the hollow piston rod 164, and the insertion parts of the hollow piston rod 164 and the rotating shaft 1662 are both non-circular in shape. The rotating shaft 1662 drives the hollow piston rod 164 to rotate. The insertion of the rotating shaft 1662 and the hollow piston rod 164 facilitates the assembly of the electronic atomizing device. The non-circular shape of the insertion parts of the hollow piston rod 164 and the rotating shaft 1662 can be regular or irregular in shape, such as elliptical, polygonal, or flower-shaped, or even irregular in shape. This allows the rotating shaft 1662 to drive the hollow piston rod 164 to rotate when the motor 166 is working, thereby driving the piston 162 to move and expel air from the liquid chamber 1222.

[0032] Please see Figure 2, in this embodiment, the piston 162 includes a sealing portion 1622 and a rotating portion 1624. The rotating portion 1624 is in a "convex" shape and sleeved on the hollow piston rod 164. The rotating portion 1624 is in gear engagement with the hollow piston rod 164. The rotating portion 1624 is embedded in the sealing portion 1622. The sealing portion 1622 seals the gap between the liquid chamber 1222 and the gas chamber 1224. That is, the "convex"-shaped rotating portion 1624 is sleeved on the hollow piston rod 164, and the middle part of the "convex" shape closely adheres to the hollow piston rod 164, and there is a relatively large gap between the edge part of the "convex" shape and the inner wall of the oil storage chamber 122; and the sealing portion 1622 covers the bottom and the edge part of the "convex" shape of the rotating portion 1624, and the sealing portion 1622 closely adheres to the inner wall of the oil storage chamber 122. When the piston 162 rotates, the rotating portion 1624 rotates to带动 the sealing portion 1622 to rotate, achieving the effect of overall rotation. The rotating portion 1624 functions to带动 the sealing portion 1622 to move, and the sealing portion 1622 functions to seal the gap between the rotating portion 1624 and the hollow piston rod 164 and the gap between the rotating portion 1624 and the inner wall of the oil storage chamber 122.

[0033] Among them, the rotating portion 1624 is made of a hard material, and the sealing portion 1622 is made of a silicone material. The rotation of the piston 162 rod带动 the rotating portion 1624 and the sealing portion 1622 to move from the gas chamber 1224 to the liquid chamber 1222 direction. Specifically, as a preference, the rotating portion 1624 can be a plastic part, and the sealing portion 1622 can be a silicone part. Because the relative hardness of the plastic part is higher than that of the silicone part, when the hollow piston rod 164 rotates to带动 the rotating portion 1624 to rotate, the magnitude and direction of force transmission are more accurate, which is beneficial to ensuring the accuracy of the movement of the piston 162, so as to ensure that the air in the liquid chamber 1222 can be completely squeezed out after the e-liquid is atomized, and avoid a small amount of air remaining in the liquid chamber 1222, which may cause the e-liquid to leak out of the liquid chamber 1222 under high temperature or low pressure conditions. Of course, in other embodiments, the rotating portion 1624 can also be a silicone part. Because the middle and edge parts of the rotating portion 1624 have a certain thickness and are not easily deformed, it can play a supporting role.

[0034] Please refer to Figure 2 , Figure 3In this embodiment, the housing 12 includes an outer shell 126 and a bottom shell 128. The outer shell 126 includes a nozzle end 1262 and an open end, and the bottom shell 128 is inserted into the open end. The hollow piston rod 164 passes through the bottom shell 128 and communicates with the nozzle end 1262. The hollow piston rod 164 divides the internal cavity formed by the outer shell 126 and the bottom shell 128 into an oil storage chamber 122 and an atomizing chamber 124, and the atomizing chamber 124 is the hollow interior of the hollow piston rod 164. The atomizing component 14 is disposed in the atomizing chamber 124. During installation, first, the piston 162 is fitted onto the hollow piston rod 164, and the piston 162 is placed in the initial position where the hollow piston rod 164 is not rotated. Then, the hollow piston rod 164 with the piston 162 fitted onto it is inserted into the outer shell 126, so that the hollow piston rod 164 is connected to the mouthpiece and fixedly sealed. To achieve a sealing effect, a sealing ring can be set at the connection between the hollow piston rod 164 and the mouthpiece. Next, the bottom shell 128 is fitted onto the hollow piston rod 164, and the bottom shell 128 is moved to the open end, so that the bottom shell 128 is inserted into the open end of the outer shell 126. Finally, the hollow piston rod 164 is inserted into the main unit 20 for installation. Of course, the atomizing component 14 needs to be installed inside the hollow piston rod 164 before the hollow piston rod 164 is inserted into the mouthpiece. The outer shell 126 can have an oil injection hole for injecting e-liquid, and the oil injection hole is connected to the liquid chamber 1222.

[0035] Furthermore, an air intake channel 1282 communicating with the outside is provided along the surface of the bottom shell 128, and an air intake hole 1644 is radially provided on the hollow piston rod 1644. The atomizing chamber 124 is connected to the air intake channel 1282 through the air intake hole 1644; air can enter the atomizing chamber 124 through the air intake hole 1644 and mix with the smoke formed by the atomized e-liquid of the atomizing component 14 for the user to inhale. The main unit 20 can be equipped with a control switch to control the power supply to the main unit 20. Preferably, the main unit 20 is controlled by a pneumatic switch. Specifically, the air intake channel 1282 is provided with a branch channel communicating with the pneumatic switch. When the user inhales the electronic atomizing device, the pneumatic switch senses the negative pressure in the branch channel and connects the circuit, energizing the atomizing component 14. This provides sensitive triggering and convenient use.

[0036] Please see Figure 2In this embodiment, the wicking hole 1642 and the atomizing assembly 14 are both located near the mouthpiece end 1262, and the liquid chamber 1222 and the gas chamber 1224 are located near the mouthpiece end 1262 and the bottom shell 128, respectively. With this arrangement, since e-liquid is heavier than gas, the piston 162 can normally expel the compressed gas through the upper wicking hole 1642. If the wicking hole 1642 were located near the bottom shell 128, it would typically be sealed by e-liquid. In this case, the compressed air would be expelled with a small amount of e-liquid, resulting in both waste and leakage. Furthermore, a liquid suction element 1242 is also provided within the atomizing chamber 124 between the atomizing assembly 14 and the bottom shell 128. The liquid suction element 1242 is a hollow ring and fits against the inner wall of the hollow piston rod 164. The high-temperature vapor generated by atomization will form a small amount of condensate after contacting the atomization chamber 124 and the mouthpiece. If the condensate flows to the bottom shell 128, it may corrode the conductive post and even the motor 166, affecting the service life of the electronic atomization device. If the condensate is inhaled by the user, it will affect the taste and user experience. The liquid absorption component 1242, which is matched and fitted to the inner wall of the atomization chamber 124, can absorb the condensate, eliminate the possible effects of the condensate, improve the service life of the electronic atomization device, and enhance the taste and user experience.

[0037] The atomizing component 14 includes an oil-guiding element and a heating element. The heating element can be a hollow tubular structure with perforations. The oil-guiding element covers the outside of the heating element and fits into the oil-guiding hole 1642. That is, the oil-guiding element absorbs the e-liquid in the liquid chamber 1222 and supplies it to the heating element for heating and atomization. The perforations ensure that the e-liquid is evenly coated on all parts of the heating element, preventing dry burning due to insufficient oil supply or no contact with e-liquid in certain areas. The hollow tubular shape of the heating element allows for airflow, providing the air needed for atomizing the e-liquid and carrying the atomized vapor along with the air to the mouthpiece for inhalation. Preferably, the oil-guiding element can be oil-guiding cotton, and the heating element can be a heating mesh, heating wire, etc.

[0038] Please see Figure 2 , Figure 3 In this embodiment, the main unit 20 is equipped with an adjustment knob 22, which adjusts the duty cycle of the motor 166. Users can adjust the duty cycle of the motor 166 according to their personal taste preferences. Different duty cycles correspond to different amounts of atomized smoke and different levels of dryness and humidity of the smoke, which can meet different needs.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
