Description

Technical Field

[0001] This utility model relates to the field of cigarette substitute technology, and in particular to an electronic cigarette with separate oil and core. Background Technology

[0002] Electronic atomizing devices are electronic products that mimic cigarettes, atomizing e-liquid into vapor for users to inhale. Due to their similar taste and ease of use to cigarettes, electronic atomizing devices have been rapidly promoted and used.

[0003] Existing electronic atomizing devices generally include a battery-operated main unit and an atomizer. The atomizer is the vapor-generating part of the electronic atomizing device, containing e-liquid. High temperatures cause the e-liquid to atomize and form vapor. The battery-operated main unit is the control center and power supply unit of the electronic atomizing device. The atomizer coil is usually in contact with the e-liquid for a long time, guiding the e-liquid through the coil. When electricity is applied, the heating wire generates high temperatures to atomize the e-liquid.

[0004] E-cigarette devices are often plagued by e-liquid leakage during storage and transportation, severely impacting user experience and operating costs. To address this issue, a coil-separation structure is typically incorporated into e-cigarette devices. This structure keeps the e-liquid separate from the coil when not in use, preventing contact and wicking between them. Common coil-separation technology involves placing a separator around the coil and applying external force to allow it to move axially or radially, thus separating or connecting the e-liquid to the coil.

[0005] However, friction or wear during the movement of the isolator can impair its sealing performance, resulting in incomplete sealing. The movement can also cause the e-liquid to be squeezed, leading to oversaturation and leakage of the atomizer coil. Furthermore, the need for a dedicated movement gap increases the internal space occupied by the atomizer, requiring a larger atomizer volume to maintain the e-liquid capacity, which also increases costs. Utility Model Content

[0026] Please see Figure 1 This is a schematic diagram of the structure of an electronic cigarette with automatic oil-core separation in one embodiment.

[0027] The e-cigarette with separate oil and core includes an atomizer 10 and a battery main unit 30. The atomizer 10 is the aerosol generator of the e-cigarette, which heats up when powered on, causing the e-liquid inside the atomizer 10 to form vapor for the user to inhale. The battery main unit 30 is the control center and power supply center of the e-cigarette. The battery 34 provides power to the entire circuit of the e-cigarette, enabling the control center to power on and control the various components in the circuit to work, so that the atomizer 10 can be powered on and heated. The atomizer 10 is compatible with the battery main unit 30.

[0028] For details, please refer to Figure 2 , Figure 3 The atomizer 10 includes a housing 12, an atomizing assembly 14, and a base 16. The housing 12 includes a mouthpiece 121 end and an open end. The base 16 is inserted into the open end, and the atomizing assembly 14 is disposed inside the housing 12. The atomizing assembly 14 includes a first dividing sleeve 142, an oil guiding element 144, and a heating element 146. The oil guiding element 144 covers the heating element 146 and is disposed inside the first dividing sleeve 142. The interior of the housing 12 is divided into an oil storage chamber 122 and an atomizing chamber 124 by the first dividing sleeve 142. The sleeve 142 has a first oil guide hole that connects the oil storage chamber 122 and the atomizing chamber 124; a guide post 126 is grown inside the housing 12 where the nozzle 121 is located; the base 16 includes a fixed seat 162 and a movable seat 164; the fixed seat 162 is inserted into the bottom of the oil storage chamber 122; the movable seat 164 is inserted into the bottom of the atomizing chamber 124; the two ends of the first separating sleeve 142 are respectively sleeved / inserted into the guide post 126 and the movable seat 164; the movable seat 164 and the atomizing assembly 14 can move axially along the guide post 126.

[0029] This oil-coil separated electronic cigarette features a guide post 126 within the housing 12 corresponding to the mouthpiece, and includes an atomizing assembly 14 and a movable base 164 that can move along the guide post 126. (See [link to relevant documentation]). Figure 2 In the initial state before using the electronic cigarette, the first separating sleeve 142 isolates the oil storage chamber 122 and the atomizing chamber 124, achieving oil-wick separation and preventing oil leakage caused by temperature and pressure changes during storage and transportation; please refer to Figure 3In use, the contact with the movable seat 164 causes the atomizing component 14 to move as a whole, connecting the oil reservoir 122 and the atomizing chamber 124 to supply e-liquid for atomization. Since the atomizing component 14 moves within the atomizing chamber 124, it does not cause pressure changes to the e-liquid in the oil reservoir 122, thus preventing leakage and improving the sealing performance of the electronic cigarette. Furthermore, the moving friction parts of the first separating sleeve 142 are equipped with elastic seals to prevent damage to the sealing performance due to friction. Moreover, no additional components are needed to separate the oil reservoir 122 and the atomizing chamber 124, saving internal space in the atomizer 10 and contributing to the compact design of the electronic cigarette.

[0030] Please see Figure 2 , Figure 3 In this embodiment, the base 16 further includes an end cap 166, which is inserted into the open end of the housing 12 and can move toward the fixed seat 162. The end cap 166 is provided with a push rod 1662, which abuts against the movable seat 164. The movement of the end cap 166 toward the fixed seat 162 causes the push rod 1662 to abut against the movable seat 164 and the atomizing component 14 to move. The side of the end cap 166 abuts against the open end and can move along the inner wall of the open end. The push rod 1662 is provided at the middle of the end cap 166 corresponding to the movable seat 164 to abut against the movable seat 164. When the end cap 166 abuts against the movable seat 164 and causes the atomizing component 14 to move, it can balance the force on the movable seat 164 and prevent the atomizing component 14 from tilting due to uneven force on the movable seat 164, which would cause the movement to be unsmooth or even leak oil.

[0031] In this embodiment, a first guide weir 1622 is provided on the side of the fixed base 162. The first guide weir 1622 is adapted to the inner wall of the open end and fits snugly during installation. A second guide weir 1664 is provided on the side of the end cover 166. The second guide weir 1664 is adapted to the inner wall of the first guide weir 1622, and the second guide weir 1664 can drive the end cover 166 to move along the inner wall of the first guide weir 1622. The first guide weir 1622 and the second guide weir 1664 are arranged in a stacked manner with the inner wall of the open end, and can be guided sequentially along the inner wall of the open end and the inner wall of the first guide weir 1622. The first guide weir 1622 and the second guide weir 1664 increase the force-bearing area of ​​the side of the fixed base 162 and the side of the end cover 166, making it less likely to deviate due to uneven force during movement. This allows each moving component to move along a preset path during installation and use, avoiding errors.

[0032] In this embodiment, a liquid storage tank 1666 is formed in the space between the end cap 166 and the second guide weir 1664, and the liquid storage tank 1666 can accommodate absorbent cotton. The liquid storage tank 1666 and the absorbent cotton can absorb the small amount of e-liquid that may be carried out during the movement of the atomizing component 14, and can also absorb the condensate that may be formed when the smoke cools during the atomization process, so as to prevent e-liquid or condensate from leaking into the battery host 30.

[0033] Please see Figure 2 , Figure 3 In this embodiment, the atomizing assembly 14 further includes a second separating sleeve 147, which is sleeved on the oil guiding element 144, and the second separating sleeve 147, the oil guiding element 144, and the heating element 146 are integrally housed within the atomizing chamber 124; the second separating sleeve 147 has a second oil guiding hole communicating with the oil guiding element 144 and the oil storage chamber 122. The first separating sleeve 142 and the second separating sleeve 147 are both inserted and fixed to the movable seat 164, and a buffer chamber 148 is provided between the first separating sleeve 142 and the second separating sleeve 147, the buffer chamber 148 being filled with oil storage cotton. By setting a buffer cavity 148 between the first separating sleeve 142 and the second separating sleeve 147, and filling the buffer cavity 148 with oil-retaining cotton, on the one hand, the oil-retaining cotton has a good oil absorption and storage function. In the initial state, the oil-retaining cotton will store a certain amount of e-liquid. When the atomizing component 14 is separated from the oil-retaining cavity 122, it provides e-liquid for the wicking element 144 to lubricate the coil. This avoids the need to wait a long time for the wicking element 144 to deliver the e-liquid required for atomization when the atomizing component 14 is connected to the oil-retaining cavity 122. It also avoids the problem of the coil burning due to heating atomization when the wicking element 144 does not deliver enough e-liquid during the waiting time. On the other hand, the oil-retaining cotton has good oil storage and locking performance. It can store e-liquid without dripping while lubricating the coil. After being connected to the oil-retaining cavity 122, it will not leak e-liquid by absorbing the e-liquid in the oil-retaining cavity 122.

[0034] In this embodiment, a limiting platform 149 is provided at the top of the buffer chamber 148 and the second separating sleeve 147. When the oil storage chamber 122 is connected to the buffer chamber 148, the limiting platform 149 abuts against the guide post 126. Both the guide post 126 and the limiting platform 149 have through holes in their middle sections, connecting the atomizing chamber 124 and the mouthpiece 121. The limiting platform 149 can restrict the stroke of the atomizing component 14 during the process of the movable seat 164 driving the atomizing component 14 to move towards the mouthpiece 121 and connecting the oil storage chamber 122, so that the atomizing component 14 moves according to the preset stroke, avoiding insufficient or excessive movement. Of course, the atomizing component 14 between the guide post 126 and the limiting platform 149 has a preset stroke for the atomizing component 14 to move.

[0035] In this embodiment, the first dividing sleeve 142 is provided with at least two first oil guide holes evenly spaced around its circumference, and the second dividing sleeve 147 is provided with at least two second oil guide holes evenly spaced around its circumference. The evenly spaced first and second oil guide holes can facilitate uniform oil supply, provide a good sucking experience, and avoid burning the oil guide element 144 due to uneven oil supply.

[0036] Please see Figure 2 , Figure 3 In this embodiment, a first sealing element 17 is provided between the housing 12, the first partition sleeve 142 and the fixed base 162; a second sealing element 18 is provided between the first partition sleeve 142, the second partition sleeve 147 and the movable base 164; a third sealing element 19 is provided between the first partition sleeve 142 and the guide post 126; and a fourth sealing element 20 is provided between the first partition sleeve 142, the second partition sleeve 147 and the limiting platform 149. The first sealing element 17 ensures the sealing performance of the bottom of the oil storage cavity 122, preventing oil leakage from the oil storage cavity 122; the second sealing element 18 ensures the sealing performance of the bottom of the buffer cavity 148, preventing oil leakage from the buffer cavity 148; the third sealing element 19 ensures the sealing performance between the first partition sleeve 142 and the guide post 126 when the first partition sleeve 142 moves along the guide post 126, preventing oil leakage; and the fourth sealing element 20 ensures the sealing performance of the top of the buffer cavity 148, preventing oil leakage. That is, sealing elements are provided at each assembly point of the components to ensure sealing performance and achieve good oil leakage prevention. Among them, the first seal 17, the second seal 18, the third seal 19, and the fourth seal 20 are preferably made of silicone sealing material.

[0037] Please see Figure 2 , Figure 3In this embodiment, the battery host 30 includes a housing 32, a battery 34, and a main control board 36. The battery 34 and the main control board 36 are housed in the housing 32. The housing 32 is provided with a plug-in end. The outer wall of the open end of the housing 12 and the inner wall of the plug-in end of the housing 32 are respectively provided with a first locking member 128 and a second locking member 322. The first locking member 128 and the second locking member 322 are compatible with each other. The first locking member 128 and the second locking member 322 are both adapted to have several positions. When the electronic cigarette is in the initial state, the atomizer 10 and the battery host 30 are locked by one of the positions, ensuring that the movable seat 164 and the atomizing component 14 are in a preset position separated from the oil reservoir 122. When the electronic cigarette needs to be used, the atomizer 10 is pressed down or the battery host 30 is pressed up, so that the atomizer 10 and the battery host 30 are squeezed against each other, so that the end cap 166 squeezes the movable seat 164 and the atomizing component 14 to move along a preset path. When it moves to the preset position, the oil reservoir 122 is connected to the atomizing component 14. At this time, the atomizer 10 and the battery host 30 are locked by another position to ensure that the atomizer 10 and the battery host 30 will not bounce back and to ensure the airtightness between the atomizer 10 and the battery host 30.

[0038] Of course, the first locking member 128 and the second locking member 322 can be matched in various ways, such as the cooperation between the latches, the cooperation of meshing teeth, the cooperation between the slide and the locking member, etc.

[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 this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
