Description

Technical Field

[0001] This utility model relates to the field of electronic atomizer technology, and in particular to a refillable leak-proof electronic atomizer. Background Technology

[0002] Electronic atomizers generally consist of a cartridge and a mod. Driven by the mod, the cartridge heats the e-liquid to produce vapor for the user to inhale. Currently, cartridges include a shell, a container holder, and an atomizing component. The container holder is sealed at the bottom of the cartridge, forming a cavity with the shell to hold the e-liquid. A cotton wick is usually placed inside the cavity to absorb the e-liquid. The atomizing component is directly inserted into the container holder and placed inside the cavity, allowing the cotton wick to wrap around and heat the component for vaporization. The vapor flows from the atomizer coil to the mouthpiece. This direct-through structure between the coil and mouthpiece can easily draw out incompletely atomized e-liquid, contaminating the mouthpiece and affecting the vaping experience. Furthermore, there is a risk of condensate flowing back into the mod, potentially damaging it. Therefore, it is necessary to improve the sealing, airflow, and e-liquid intake structures of the atomizer. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned defects in the prior art and provide a refillable leak-proof electronic atomizer. This invention improves the flue structure and enhances the internal sealing performance to prevent oil leakage from entering the main unit and corroding the components on the main unit, thus preventing malfunctions.

[0004] To achieve the above objectives, this utility model provides a refillable leak-proof electronic atomizer, comprising:

[0005] The cartridge includes a mouthpiece, a first oil cup holder, a second oil cup holder, and an atomizing component. A first mounting cavity is formed on the first oil cup holder. The second oil cup holder is inserted into the first mounting cavity and fastened to the first oil cup holder. The mouthpiece wraps around the second oil cup holder and fastens to the first oil cup holder. The upper end of the mouthpiece has a mouthpiece opening, and an outlet channel communicating with the mouthpiece opening is provided inside the mouthpiece. A first air outlet communicating with the outlet channel is provided on the second oil cup holder. A first flow channel communicating with the first air outlet and the first mounting cavity is provided on the second oil cup holder. A first air inlet communicating with the first mounting cavity is provided on the first oil cup holder. An oil storage cavity is provided inside the second oil cup holder. A second through hole communicating with the oil storage cavity is opened on the second oil cup holder, and the second through hole is completely sealed and isolated from the first air outlet. The upper end of the atomizing component is placed in the oil storage cavity, and the lower end of the atomizing component is placed in the first mounting cavity, with a first conductive terminal leading out and passing through the first mounting cavity.

[0006] The main unit includes a main unit casing, a battery bracket disposed inside the main unit casing, a battery assembly, and a control assembly. The battery bracket is provided with an adsorption assembly connected to the tobacco cartridge and a second conductive terminal. The second conductive terminal is used to connect the first conductive terminal and the control assembly.

[0007] Furthermore, it also includes a third oil cup holder, which has a second air outlet and a third through hole. The third oil cup holder has a wrapping cavity, within which a plug-in post is located. The third through hole is located within the plug-in post. The wrapping cavity wraps around the upper end of the second oil cup holder and engages with it, allowing the plug-in post to be inserted into the first air outlet, thus completely sealing and isolating the second through hole and the first air outlet. The plug-in post effectively isolates the first air outlet from the second through hole, preventing condensate or e-liquid from overflowing from the mouthpiece and affecting the inhalation experience.

[0008] Furthermore, the inner wall of the second vent is provided with a first engaging protrusion that abuts against the outer wall of the outlet channel, and the outer wall of the second oil cup bracket is provided with a second engaging protrusion that abuts against the inner wall of the encapsulation cavity. The provision of the first and second engaging protrusions enhances the sealing and connection stability between the structures, thereby improving the overall leak-proof performance of the device.

[0009] Furthermore, it also includes a first sealing element, which is a ring structure. The first sealing element wraps around the upper end of the atomizing component and engages with the inner wall of the oil storage chamber. This is used to seal the atomizing component and reduce the risk of leakage.

[0010] Furthermore, the first mounting cavity is provided with a plurality of first pillars and second pillars, and the first air inlet is disposed in the first pillar. A third through hole is provided on the second pillar for connecting the first conductive terminal. The first mounting cavity is filled with first oil-absorbing cotton, which has through holes matching the first and second pillars. By providing the first oil-absorbing cotton, the condensate generated during atomization can be effectively absorbed, reducing the impact of condensate accumulation on the conductive terminal and improving the safety and stability of the device.

[0011] Furthermore, it also includes a second oil-absorbing cotton, which is attached to the upper side of the first mounting cavity, separating the atomizing component from the first air inlet. The second oil-absorbing cotton has several vent holes. While ensuring unobstructed airflow, it works in conjunction with the first oil-absorbing cotton to form a double absorption system, further preventing the risk of leakage due to condensate buildup.

[0012] Furthermore, a first inner groove is provided at the bottom end of the first oil cup holder, and the third through hole is placed within the first inner groove. A metal connector is connected to the end of the first conductive terminal. When the first conductive terminal is inserted into the third through hole, the metal connector is placed within the first inner groove. The metal connector enables the adsorption connection between the e-cigarette cartridge and the main unit, while ensuring stable contact between the conductive terminal and the main unit circuit, thus improving the overall conductivity and safety of the device.

[0013] Furthermore, the upper end of the battery holder forms a second mounting cavity, and a first mounting groove matching the position of the first inner groove is provided in the second mounting cavity. The adsorption component is disposed in the first mounting groove, and the cartridge and the battery holder are quickly connected and firmly fixed through magnetic attraction, while facilitating disassembly and replacement.

[0014] Furthermore, the battery holder has a first air inlet groove and a second air inlet hole for connecting the second mounting cavity and the first air inlet groove along its outer periphery, and a third air inlet hole communicating with the first air inlet groove is provided on the main unit housing. This forms a stable air intake channel, providing sufficient air input for atomization.

[0015] Furthermore, a connecting notch is provided on the wall of the first air intake slot. This connecting notch connects the first air intake slot to the third air intake port, enhancing the airflow efficiency between the air intake slot and the outside air, and further improving the airflow stability of the device during use.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. This utility model achieves complete separation of the air intake and oil passage by optimizing the internal structure of the mouthpiece, the first oil cup bracket, the second oil cup bracket and the third oil cup bracket. That is, the mouthpiece is provided with an outlet channel, which together with the first mounting cavity of the first oil cup bracket, the first air outlet and the first flow channel of the second oil cup bracket, and the second air outlet and the plug-in column inside the third oil cup bracket form an independent air intake channel.

[0018] The oil inlet channel is formed by the oil storage chamber and second through hole of the second oil cup bracket, and the third through hole of the third oil cup bracket. The air intake channel and the oil inlet channel are completely separated. This independent operating mechanism ensures that the air intake process is only responsible for air circulation, while the oil delivery process focuses on the delivery of e-liquid. This fundamentally eliminates the possibility of e-liquid overflowing into the mouthpiece due to pressure changes or design defects. This not only avoids the discomfort and pollution caused by e-liquid entering the user's mouth when inhaling, but also improves the overall smoothness and comfort of inhaling, ensuring that every use is safer and more reliable.

[0019] 2. This utility model adopts a multi-level layered sealing structure and sets snap-fit ​​protruding rings on each sealing structure, which can significantly improve the overall sealing performance and structural stability of the product. On this basis, a first sealing element is set to seal the oil storage chamber, and a double layer of oil-absorbing cotton (i.e., the first oil-absorbing cotton and the second oil-absorbing cotton) is set in the second installation chamber to work together to form multiple physical barriers and adsorption barriers. It can efficiently intercept and absorb any condensate or residual e-liquid that may be generated, effectively preventing it from seeping or leaking outward along gaps or structural gaps. This not only completely solves the risk of leakage, but also fundamentally ensures the safe operating environment of the internal components of the host, thereby greatly enhancing the stability and reliability of the equipment during long-term use and significantly extending the overall service life of the product.

[0037] like Figures 1 to 11 The present invention discloses a refillable leak-proof electronic atomizer, comprising a cartridge 1 and a main unit 2;

[0038] like Figures 1 to 3 As shown, the cartridge 1 is connected to the main body by an adsorption connection, specifically by a magnetic connection. In this embodiment, the cartridge 1 includes a mouthpiece 11, a first oil cup holder 12, a second oil cup holder 13, a third oil cup holder 14, an atomizing component 15, and a first sealing element 16.

[0039] After the battery holder 22 is inserted into the main unit housing 21, a connection space adapted to the e-cigarette cartridge 1 is formed at the upper end of the main unit housing 21, which facilitates the insertion of the e-cigarette cartridge 1. After the e-cigarette cartridge 1 is inserted into the connection space, a stable connection is achieved through magnetic attraction.

[0040] like Figure 2 As shown, the upper end of the mouthpiece 11 is provided with a mouthpiece opening 111, and an outlet channel 112 communicating with the mouthpiece opening 111 is provided inside the mouthpiece 11. The outlet channel 112 is formed by a tubular structure provided inside the mouthpiece 11, which can separate the outlet channel 112 from other spaces inside the mouthpiece 11.

[0041] like Figures 5 to 8The first oil cup bracket 12 forms a first mounting cavity 121, and the second oil cup bracket 13 is inserted into the first mounting cavity 121 and fastened to the first oil cup bracket 12. Specifically, a first insertion part 131 is formed at the lower end of the second oil cup bracket 13, and first snap-fit ​​protrusions 1311 are provided on both sides of the first insertion part 131. A second snap-fit ​​protrusion 122 and a first snap-fit ​​through hole 123 that cooperates with the first snap-fit ​​protrusion 1311 are formed on the first oil cup bracket 12. During assembly, the first insertion part 131 is directly inserted into the first mounting cavity 121, so that the first snap-fit ​​protrusion 1311 is fastened to the first snap-fit ​​through hole 123. In this embodiment, the third oil cup bracket 14 is provided with a covering cavity 141. The frame 14 has a third snap-fit ​​groove 142 at both ends, and a third snap-fit ​​protrusion 132 at the upper ends of both sides of the second oil cup bracket 13. During assembly, the bracket will wrap the upper end of the second oil cup bracket 13 with the enclosing cavity 141, and the third snap-fit ​​groove 142 and the third snap-fit ​​protrusion 132 will be press-fitted to achieve the snap-fit ​​between the third oil cup bracket 14 and the second oil cup bracket 13. A second snap-fit ​​groove 113 is provided on the inner wall of the lower end of the mouthpiece 11 to cooperate with the second snap-fit ​​protrusion 122. After the second oil cup bracket 13 and the first oil cup bracket 12 are snapped together, the mouthpiece 11 directly wraps the third oil cup bracket 14, the second oil cup bracket 13 and the first oil cup bracket 12. The connection between the three is relatively fixed by the snap-fit ​​between the second snap-fit ​​protrusion 122 and the second snap-fit ​​groove 113.

[0042] In this embodiment, a first vent 133 communicating with the outlet channel 112 is provided on the second oil cup support 13, and a second vent 143 and a third through hole 144 are provided on the third oil cup support 14. An insertion post 145 is provided inside the enclosing cavity 141, through which the second vent 143 is formed. The outer diameter of the insertion post 145 is smaller than the inner diameter of the first vent 133. When the third oil cup support 14 and the second oil cup support 13 are fastened together, the insertion post 145 is directly inserted into the first vent 133, achieving communication between the first vent 133 and the second vent 143. Similarly, the outlet on the mouthpiece 11... The outer diameter of the channel 112 is smaller than the inner diameter of the second air outlet 143. After assembly, the outlet channel 112 is directly inserted into the second air outlet 143, thereby achieving communication between the second air outlet 143 and the outlet channel 112. The front and rear sides of the second oil cup bracket 13 are connected to the first air outlet 133 and the first flow channel 134 of the first mounting cavity 121. The first oil cup bracket 12 is provided with a first air inlet 124 that communicates with the first mounting cavity 121.

In this embodiment, a total of two second through holes 137 and two third through holes 144 are provided. The positions of the second through holes 137 and the third through holes 144 are correspondingly arranged and are respectively placed on both sides of the first vent hole 133 and the second vent hole 143. The insertion column 145 is connected to the outlet through hole. All channels 112 are hollow tubular structures. Therefore, when the insertion column 145 is inserted into the first air outlet 133, the second through hole 137 and the first air outlet 133 are completely sealed and isolated. When the outlet channel 112 is inserted into the second air outlet 143, the third through hole 144 and the second air outlet 143 are completely sealed and isolated.

Preferably, an oil filling hole can be provided on the side of the mouthpiece 11, and the oil filling hole can directly enter the third through hole 144 to fill oil.

[0045] In this embodiment, a first sealing member 16 is also included. The first sealing member 16 has a ring structure. After the first sealing member 16 wraps around the upper end of the atomizing component 15, it is engaged with the inner wall of the oil storage cavity 136, so that the upper end of the atomizing component 15 is placed in the oil storage cavity 136 to absorb e-liquid.

The second pillar 126 is provided with a third through hole 144. The first mounting cavity 121 is filled with a first oil-absorbing cotton 4. The first oil-absorbing cotton 4 is provided with through holes that match the first pillars 125 and second pillars 126. Specifically, the first conductive terminal 3 is provided with a first inner groove 127 at the bottom end of the first oil cup bracket 12. The third through hole 144 is placed in the first inner groove 127. The end of the first conductive terminal 3 is connected to a metal connector 31. The other end of the first conductive terminal 3 passes through the third through hole 144 and is connected to the atomizing component 15. The metal connector 31 is fixed in the first inner groove 127.

[0047] Preferably, it also includes a second oil-absorbing cotton 5, which is attached to the upper side of the first mounting cavity 121 to separate the atomizing component 15 and the first air inlet 124. Several air vents are provided on the second oil-absorbing cotton 5.

[0048] The battery holder 22 is provided with an adsorption component 6 connected to the cartridge 1 and a second conductive terminal 7. The second conductive terminal 7 is used to connect the first conductive terminal 3 and the control component 24. In this embodiment, the adsorption component 6 is a permanent magnet. A second mounting cavity 221 is formed at the upper end of the battery holder 22. A first mounting groove 222 that matches the position of the first inner groove 127 is provided in the second mounting cavity 221. The adsorption component 6 is disposed in the first mounting groove 222. The adsorption connection between the cartridge 1 and the main unit 2 is realized by the cooperation of the adsorption component 6 and the metal connector 31.

[0049] like Figure 2 , Figure 10 and Figure 11 As shown, the battery bracket 22 has a first air inlet groove 223 and a second air inlet hole 224 for connecting the second mounting cavity 221 and the first air inlet groove 223 on its outer periphery. The main housing 21 has a third air inlet hole 211 communicating with the first air inlet groove 223. A connecting notch 225 is formed in the wall of the first air inlet groove 223. The connecting notch 225 enables communication between the first air inlet groove 223 and the third air inlet hole 211, enhancing the airflow efficiency between the air inlet groove and the outside air, and further improving the airflow stability of the device during use.

[0050] Preferably, a fourth through hole 226 is also provided on the battery holder 22, and the fourth through hole 226 is connected to the microphone 8 for automatic control of opening and closing during inhalation.

[0051] The control component 24 includes a control board 241, a display screen 242, and control buttons 243. The control board 241 is electrically connected to the battery and is used to adjust the atomization temperature and power output. The display screen 242 is located on the surface of the main unit housing 21 and is used to display the current operating parameters and the remaining battery power. The control buttons 243 are located on one side of the main unit housing 21 and can be adjusted to switch between different power modes and turn the entire unit on and off.

[0052] The airway flow direction of this invention is such that during inhalation, if... Figure 11 As shown, the third air inlet 211 is positioned between the cartridge 1 and the battery holder 22. Airflow enters the main unit 2 from the third air inlet 211 on both sides of the main unit housing 21, and then enters the first air inlet slot 223 through the connecting notch 225. The airflow flows along the first air inlet slot 223 and enters the second mounting cavity 221 through the second air inlet 224. Then, the airflow enters the first mounting cavity 121 from the first air inlet 124, providing the basis for atomization of the atomizing component 15. The smoke generated by the atomization of the atomizing component 15 flows sequentially to the first circulation channel 134, the first air outlet 133, the second air outlet 143, the outlet channel 112, and finally outputs smoke from the mouthpiece 111.
