Description

Technical Field

[0001] This disclosure relates to the field of electronic cigarette technology, and more particularly to an electronic cigarette with a filter tip and a rotating structure. Background Technology

[0002] Electronic cigarettes are products that use electric heating of e-liquid to form aerosol vapor particles. Their core components include, but are not limited to, an atomizer coil, a reservoir, a control board, and a battery. The atomizer coil is activated via a button or a microphone airflow sensor, causing the heating coil element to heat up, which in turn heats the e-liquid introduced into the coil from the reservoir, producing aerosol vapor particles. In the initial stages of e-cigarette use, the submicron-sized aerosol formed after atomization may carry tiny particles (such as metal debris and aging residue from the atomizer coil), as well as liquid residues (containing propylene glycol, glycerin, flavorings, and nicotine) produced after the aerosol condenses upon cooling. Directly ingesting this condensate can result in a sticky or harsh mouthfeel. Therefore, some existing e-cigarette products incorporate a filter at the mouthpiece to absorb these substances. However, this filter is typically not replaced, easily accumulating condensate and losing its original function. Therefore, existing e-cigarette products need optimization and improvement to address these technical issues. Utility Model Content

[0003] In view of this, the present disclosure proposes an electronic cigarette with a filter and a rotating structure, which has a storage cavity for storing the filter and can store at least two filters for replacement. The storage cavity adopts a rotating structure cover, which can achieve a simple and beautiful electronic cigarette product.

[0004] According to one aspect of this disclosure, an electronic cigarette with a filter and a rotating structure is provided, including an electronic cigarette shell, an oil cup disposed within the electronic cigarette shell, a control board, and a battery cell. The oil cup contains an atomizing core, and its upper and lower ends are respectively provided with an air outlet and an air inlet communicating with the atomization channel within the atomizing core. The atomizing core is electrically connected to the control board, and the battery cell is also electrically connected to the control board. The upper end of the electronic cigarette shell is a first opening. The oil cup is fitted inside the electronic cigarette shell, offset to one side. The outer wall of the oil cup and the inner wall of the electronic cigarette shell form a receiving cavity, which accommodates at least two filters. A top cover is provided at the first opening. The top cover has a insertion hole corresponding to the air outlet of the oil cup. The top cover rotates circumferentially around the insertion hole to open or close the first opening. The filters are removed from the receiving cavity and inserted into the insertion hole.

[0005] As one of the preferred options, the filter nozzle is a cylindrical filter cotton rod, which is made of one piece of cotton with through holes at the top and bottom of the shaft.

[0006] Furthermore, an inverted L-shaped bracket is fastened to the upper end of the storage cavity and oil cup. The inverted L-shaped bracket includes a hollow cavity that is vertical and open at the top. The upper end of the hollow cavity is a seat that is embedded in the first opening. At least two insertion cavities are arranged side by side in the hollow cavity. The insertion cavities are used to accommodate the filter nozzle. The outer edge of the seat is tightly connected to the first opening. The seat has a matching interface at the air outlet. The insertion through hole of the upper cover is inserted into the matching interface and can rotate circumferentially along the matching interface.

[0007] As one of the preferred embodiments, the base body has at least one groove between the interface and the upper opening of the hollow cavity, a first magnet is embedded in the groove, and a second magnet that is magnetically attracted to the first magnet is embedded in the bottom of the upper cover. When the first magnet and the second magnet are attracted to each other, the upper cover and the first opening are in a closed state.

[0008] Furthermore, the oil cup includes an upper shell, an integrated oil storage cotton, and a bottom shell. The upper shell has an air outlet at the top and a hollow internal structure. The integrated oil storage cotton is fitted inside the upper shell and has a through hole corresponding to the air outlet. An atomizing core is fitted inside the through hole. The bottom shell covers the bottom of the upper shell and has an air inlet corresponding to the lower end of the atomizing core.

[0009] Furthermore, the electronic cigarette casing includes a bottom shell and a hollow straight tubular shell with a first opening at the top and a second opening at the bottom. The control board and the battery cell are installed inside the bottom shell. The control board is equipped with an airflow sensor. An air inlet is provided at the bottom of the bottom shell. The bottom shell is inserted into the second opening of the hollow straight tubular shell for fixed connection.

[0010] Furthermore, the bottom shell of the oil cup extends toward the storage cavity with a platform position. The bottom edge of the bottom shell of the oil cup and the platform position is provided with a positioning protrusion and a snap-fit ​​hook. The upper edge of the bottom shell is provided with a notch that aligns with the positioning protrusion and a snap-fit ​​opening that snaps with the snap-fit ​​hook.

[0011] The electronic cigarette with a filter and rotating structure designed in this technical solution has the following advantages: Compared to traditional electronic cigarettes where the filter and e-cigarette are separate products requiring separate purchase and storage, and where the filter is removed from its storage box and inserted into the e-cigarette's original inhalation port when needed, this solution solves the problem of inconvenient filter carrying and storage. The electronic cigarette itself has a built-in filter storage cavity, and the rotating top cover allows for opening or closing of the first opening at the top of the e-cigarette. Operation is simple, convenient, and quick. Furthermore, when not in use, the filter is stored in the storage cavity, making the e-cigarette more aesthetically pleasing and promoting filter hygiene.

[0018] The technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this disclosure.

[0019] Please refer to Figures 1 to 5 This is a specific embodiment of an electronic cigarette with a filter and a rotating structure listed in this technical solution. This embodiment shows a specific electronic cigarette shape structure that realizes this technical solution, but its specific shape is not limited to this embodiment. It may also include, but is not limited to, shapes with a rectangular, square, or elliptical cross-section.

[0020] An electronic cigarette with a filter and a rotating structure in this embodiment includes an electronic cigarette shell 1, an oil cup 2 disposed inside the electronic cigarette shell 1, a control board and a battery cell. The oil cup 2 is provided with an atomizing core. The upper and lower ends of the oil cup 2 are respectively provided with an air outlet 031 and an air inlet communicating with the atomization channel inside the atomizing core. The atomizing core is electrically connected to the control board, and the battery cell 6 is electrically connected to the control board. The upper end of the electronic cigarette shell 1 is a first opening 011. The oil cup 2 is fitted inside the electronic cigarette shell 1 and offset to one side. The outer wall of the oil cup 2 and the inner wall of the electronic cigarette shell 1 form a storage cavity. The storage cavity can accommodate at least two filter tips 3. A top cover 4 is provided at the first opening 011. The top cover 4 is provided with a insertion hole 401 corresponding to the air outlet 031 of the oil cup 2. The top cover 4 rotates circumferentially around the insertion hole 401 to cover or close the first opening 011. The filter tip 3 is taken out from the storage cavity and inserted into the insertion hole 401.

[0021] In a preferred embodiment, the filter nozzle 3 is a cylindrical filter cotton rod, which is made of one-piece cotton with through holes at both ends. The one-piece cotton is made of polyester fiber material, which is made by carding, web laying and needle punching reinforcement. It has very good oleophilicity and can quickly absorb oil and condensate dozens of times its own weight. It also has the characteristics of high temperature resistance, low resistance and fast filtration speed, making it the preferred material for making the filter nozzle 3.

[0022] In this embodiment, as a preferred option, an inverted L-shaped bracket 5 is fastened to the upper end of the storage cavity and oil cup 2. The inverted L-shaped bracket 5 includes a vertical hollow cavity 05 with an open upper end. The upper end of the hollow cavity 05 is a seat 06 embedded in the first opening 011. The hollow cavity 05 has at least two insertion cavities arranged side by side. The insertion cavities are used to accommodate the filter nozzle 3. The outer edge of the seat 06 is tightly connected to the first opening 011. The seat 06 has a connecting interface 061 at the air outlet. The insertion through hole 401 of the upper cover 4 is inserted into the connecting interface 061 and can rotate circumferentially along the connecting interface 061. Setting the inverted L-shaped bracket 5 allows the hollow cavity 05 to serve as an independent storage cavity for the filter nozzle 3. On the one hand, it is beneficial to the stability of the assembly structure, and on the other hand, the size of the insertion cavity and the filter nozzle 3 are compatible, preventing the filter nozzle 3 from shaking inside. On the other hand, the filter tip 3, which absorbs e-liquid and condensate, is inserted into the hollow cavity position 05, so it will not contaminate the interior.

[0023] In a preferred embodiment, the base 06 has at least one recess between the interface 061 and the upper opening of the hollow cavity 05. A first magnet 062 is embedded in the recess, and a second magnet is embedded at the bottom of the upper cover 4, which is magnetically attracted to the first magnet 062. When the first magnet 062 and the second magnet are attracted, the upper cover 4 is in a closed state with the first opening 011. By setting the magnetic attraction between the first magnet 062 and the second magnet, it can be achieved that when the upper cover 4 rotates to the position of magnetic attraction, it is exactly the position where the upper cover 4 closes the first opening 011. This facilitates quick positioning and closure of the first opening 011, and also facilitates the connection and fixation of the upper cover 4, making it less prone to shaking.

[0024] In this embodiment, the oil cup 2 includes an upper shell 03, an integrated oil storage cotton, and a bottom shell 04. The upper shell 03 has an air outlet 031 at its upper end and is hollow inside. The integrated oil storage cotton is fitted inside the upper shell 03, and has a through-hole corresponding to the air outlet position, with an atomizing core housed inside the through-hole. The bottom shell 04 covers the bottom of the upper shell 03 and has an air inlet corresponding to the lower end of the atomizing core. Using the integrated oil storage cotton as the oil reservoir in the oil cup 2 reduces the requirements for the oil sealing components compared to open-oil oil cups, making leakage less likely. Of course, this technical solution can be adapted to be used in open-oil electronic cigarettes.

[0025] In this embodiment, to facilitate the assembly of the electronic cigarette components, the electronic cigarette housing 1 includes a bottom housing 02 and a hollow straight tubular housing 01 with a first opening 011 at the upper end and a second opening at the lower end. The control board and the battery cell 6 are installed inside the bottom housing 02. The control board is equipped with an airflow sensor, and the bottom of the bottom housing 02 is provided with an air inlet. The bottom housing 02 is inserted into the second opening of the hollow straight tubular housing 01 for fixed connection. The oil cup bottom housing 04 extends toward the storage cavity with a platform position 041. The bottom edge of the oil cup bottom housing 04 and the platform position 041 is provided with a positioning protrusion 042 and a snap-fit ​​hook 043. The upper edge of the bottom housing 02 is provided with a notch 021 that aligns with the positioning protrusion 042 and a snap-fit ​​opening 022 that snaps with the snap-fit ​​hook 043.

[0026] Please refer to Figures 2 to 5 This solution solves the problem of inconvenience in carrying and storing the filter tip 3. The electronic cigarette designed in this way has a hollow cavity 05 for storing the filter tip 3, and the first opening 011 at the top of the electronic cigarette can be opened or closed by rotating the top cover 4. The operation is simple, convenient and quick. When the filter tip 3 is not in use, it can be stored in the hollow cavity 05, making the electronic cigarette more concise and beautiful, and also conducive to the cleanliness and hygiene of the filter tip 3.
