Description

Technical Field

[0001] This utility model relates to the technical field of electronic atomizers, and in particular to an electronic atomizer. Background Technology

[0002] A paste-type atomizer is a type of electronic hookah. Traditional paste-type atomizers typically consist of three separate parts: a paste container, a paste scoop, and the atomizer. The paste container contains a highly concentrated paste. The user scoops a small amount of paste using the scoop and places it into the heating chamber of the atomizer. The atomizer is then turned on to preheat and heat the paste, and the user inhales the resulting aerosol.

[0003] To filter and dilute the generated aerosol, some vape paste atomizers are often integrated with a filter container, thus forming a filterable e-hookah, or e-hookah. For example... Figure 1 As shown, the electronic hookah includes an atomizer 1, a filter container 2, and an air tube 3. The filter container 2 is usually filled with purified water for filtering and diluting the vapor. To improve the filtration effect, the bottom of the air tube 3 extends almost entirely into the bottom of the filter container 2, meaning that most of the air tube 3 is submerged in the water. The vapor produced by the atomizer 1 is guided by the air tube 3 and first filtered and diluted in the water. The vapor overflowing from the water then passes through the suction device and is inhaled by the user.

[0004] In this electronic hookah, the entire airway is separated into two chambers by water, with the water level serving as the boundary. The side leading to the air inlet is called the front chamber, and the side leading to the mouthpiece is called the rear chamber. The liquid levels in the front and rear chambers are at the same height (forming a communicating vessel). When inhaling, the entire airway is open under the suction force of the mouthpiece, and at this time, there is no water inside the air duct 3. When inhaling stops, water re-enters the air duct 3, isolating the front and rear chambers. During this process, the gas inside the front chamber (a mixture of smoke and air) is impacted by the backflow of water in the air duct 3, causing it to be squeezed out along the air inlet (including all permeable gaps) (the more water flows back into the air duct 3, the more pronounced this effect). The macroscopic phenomenon is that when inhaling stops, smoke rushes out from the air inlet, affecting the user experience and lowering the product's image in the user's mind. Utility Model Content

DETAILED DESCRIPTION

[0039] To further clarify the technical means and effects adopted by the present application to achieve the predetermined purposes of the application, the specific embodiments, structures, features and effects of the electronic atomizer according to the present application are described in detail as follows in combination with the drawings and preferred embodiments:

[0040] Figure 2 is one of the structural schematic diagrams of the electronic atomizer in the present application. Figure 3 is another of the structural schematic diagrams of the electronic atomizer in the present application. Figure 4 is a third of the structural schematic diagrams of the electronic atomizer in the present application. Figure 5 is a fourth of the structural schematic diagrams of the electronic atomizer in the present application.

[0041] As Figures 2 to 5As shown, the utility model provides an electronic atomizer for cooperation with filter container 200. The electronic atomizer includes atomizer main body 100 and air guide pipe 300, one end of atomizer main body 100 is provided with fixed part 21 connected with filter container 200, one end of air guide pipe 300 is connected with atomizer main body 100, the other end of air guide pipe 300 is used to extend into filter liquid 210 of filter container 200, air guide pipe 300 is equipped with anti -backflow structure, and anti -backflow structure is used at least to prevent, reduce or slow down filter liquid 210 backflow into air guide pipe 300. Wherein, filter container 200 and the fixed part 21 of atomizer main body are detachably connected, and air guide pipe 300 is installed on the connecting part 211 of fixed part 21. Filter container 200 is used to pack filter liquid 210 (for example water), and the end of air guide pipe 300 away from fixed part 21 extends below water surface, so that the smoke flowing out of air outlet 104 is filtered and diluted by water, then flows into air suction passage 106 by back air inlet 105, and is sucked by user through suction nozzle 11.

[0042] The application sets backflow structure on air guide pipe 200, and the anti-backflow structure is used at least to prevent, reduce or slow down filter liquid 210 backflow into air guide pipe 200, so that the backflow of filter liquid 210 into air guide pipe 200 can be avoided, reduced or slowed down, the phenomenon of smoke backflow at air inlet 101 of atomizer main body is avoided or alleviated, the use experience of user is increased, and the image of product in the mind of user is improved.

[0043] In the embodiment, as shown, Figure 2 As shown, the length of anti-backflow structure is 2-7mm along the extension direction of air guide pipe 300. For example, the length of air guide pipe 300 extending into filter liquid 210 along the extension direction (i.e. length direction) of air guide pipe 300 is 2-7mm, that is, the height difference H between the end of air guide pipe 300 extending into filter liquid 210 and liquid surface 220 is 2-7mm. The length of air guide pipe 300 extending into filter liquid 210 is for example 5mm, so that the length of air guide pipe 300 extending into filter liquid 210 is shortened, and the amount of water backflowing into air guide pipe 300 is greatly reduced after the design.

[0044] Further, the anti-backflow structure includes a venting conduit plug 310, which is installed at the end of the air conduit 300 extending into the filtering liquid 210, and is used to reduce or slow down the backflow of the filtering liquid 210 into the air conduit 300. That is, the venting conduit plug 310 is arranged at the end of the air conduit 300 extending into the filtering liquid 210, and fills the cavity at the end of the air conduit 300 extending into the filtering liquid 210 as much as possible. In this way, the amount of water flowing back into the air conduit 300 is insufficient to cause the problem of backflow of product smoke.

[0045] In one embodiment, as shown in Figure 3 the anti-backflow structure includes a one-way valve 320, which is installed in the air conduit 300, and is used to prevent the backflow of the filtering liquid 210 into the air conduit 300. That is, the one-way valve 320 can only allow the gas in the air conduit 300 to enter the filtering liquid 210, and prevent the filtering liquid 210 from flowing back into the air conduit 300, thereby avoiding the problem of backflow of product smoke.

[0046] In one embodiment, as shown in Figure 4 the anti-backflow structure includes a tapered structure of the air conduit 300, which gradually reduces in diameter towards the filtering liquid 210. That is, the cavity at the end of the air conduit 300 extending into the filtering liquid 210 is reduced, so that the amount of water flowing back into the air conduit 300 is insufficient to cause the problem of backflow of product smoke.

[0047] In one embodiment, as shown in Figure 5 the air conduit 300 includes a first conduit 300a, and the anti-backflow structure includes a second conduit 300b, which is located at the end of the first conduit 300a towards the filtering liquid 210, and has a smaller diameter than the first conduit 300a. That is, the cavity at the end of the air conduit 300 extending into the filtering liquid 210 is reduced, so that the amount of water flowing back into the air conduit 300 is insufficient to cause the problem of backflow of product smoke.

Among them, the air inlet 101, the atomization cavity 102, the first air inlet channel 103a, the first air suction channel 106a, the air suction port 107 and the suction nozzle 11 are all arranged on the upper body 10. The air outlet 104, the air return port 105, the second air inlet channel 103b, the second air suction channel 106b and the fixed part 21 are all arranged on the lower body 20. A switch mechanism is arranged between the upper body 10 and the lower body 20, which is used to control the conduction and closing between the first air inlet channel 103a and the second air inlet channel 103b, and the conduction and closing between the first air suction channel 106a and the second air suction channel 106b. When the atomizer body 100 is not needed, the air inlet channel 103 and the air suction channel 106 are closed through the switch mechanism, so that even in the case of shaking or overturning the filter container 200, such as in the scene of being put in a bag, on a car, or in a hand, etc., the water in the filter container 200 can be prevented from entering the atomizer body 100 through the air channel (air inlet channel 103 and air suction channel 106), so as to prevent the atomizer body 100 from being damaged.

[0051] Further, the side of the upper body 10 facing the lower body 20 is provided with a first interface 103c communicating with the first air inlet channel 103a, and a second interface 106c communicating with the first air suction channel 106a, and the side of the lower body 20 facing the upper body 10 is provided with a third interface 103d communicating with the second air inlet channel 103b, and a fourth interface 106d communicating with the second air suction channel 106b, the first interface 103c cooperates with the third interface 103d, and the second interface 106c cooperates with the fourth interface 106d.

[0052] The upper body 10 and the lower body 20 are rotationally connected. When the upper body 10 rotates relative to the lower body 20 to the open position, the first interface 103c corresponds to and opens the third interface 103d, and the second interface 106c corresponds to and opens the fourth interface 106d, so as to open the first air inlet 103a and the second air inlet 103b, and open the first air inlet 103a and the second air inlet 103b, thereby facilitating the user to suck the smoke.

[0055] Furthermore, a sealing element 22 is provided between the upper body 10 and the lower body 20. Both the air inlet 103 and the air intake 106 pass through the sealing element 22, preventing air leakage at the contact surface between the upper body 10 and the lower body 20. The sealing element 22 can be made of silicone, which has a certain degree of elasticity to enhance the sealing effect.

By providing the connecting part 211 with the external air guide tube 300, the size of the atomizer body can be further reduced for easy carrying. The air guide tube 300 can be a regular beverage straw, allowing any beverage straw to be assembled with the connecting part 211. Of course, the atomizer body 100 can also be equipped with a separate air guide tube 300, which can be a flexible tube or detachably connected to the connecting part 211 for easy carrying. Alternatively, the fixing part 21 can be made longer to eliminate the need for an additional air guide tube 300, but this would increase the size of the atomizer body 100 and make it less portable.

[0057] Furthermore, the fixing part 21 is also provided with a fixing mechanism 212 that mates with the filter container 200. The fixing mechanism 212 can be a threaded structure or a snap-fit ​​structure that mates with the filter container 200, thereby achieving a detachable connection with the filter container 200.

Preferably, the fixing mechanism 212 is detachably connected to the fixing part 21, thereby facilitating the replacement of fixing mechanisms 212 of different specifications and types for installation on different filter containers 200, increasing applicability. Of course, multiple fixing mechanisms 212 of different types or specifications can also be provided on the fixing part 21, such as multiple threaded structures of different specifications, so that they can be connected to multiple different filter containers 200.

[0058] In this embodiment, the oil cup 40 is provided with a heating element 41 and a heat insulation cotton 42.

The sealing cover 121 is detachably connected with the atomizer main body 100, for example, can be detached or flipped open to leak out or close the material adding port 108. When it is necessary to add tobacco extract to the oil cup 40, the sealing cover 121 can be opened to add tobacco extract to the oil cup 40. After the addition is completed, the sealing cover 121 is closed to seal the oil cup 40.

[0060] The upper main body 10 of the atomizer main body 100 is provided with a mouthpiece cover 122 used to cover the mouthpiece 11.

Optionally, the mouthpiece 11 and the material adding port 108 are arranged on the top of the upper main body 10, and the mouthpiece cover 122 can cover the mouthpiece 11 and the material adding port 108 at the same time.

[0061] Further, the atomizing cavity 102 is provided with an oil absorption cotton 131 corresponding to the atomizing core 30. The oil absorption cotton 131 is located below the atomizing core 30, thereby absorbing the tobacco extract that is not completely atomized, avoiding the tobacco extract from blocking the air inlet 103. Optionally, the atomizing cavity 102 is provided with a smoke blocking sheet 132 arranged between the atomizing core 30 and the oil absorption cotton 131. The smoke blocking sheet 132 can reduce the contact between the smoke and the oil absorption cotton 131, thereby reducing the absorption of the smoke by the oil absorption cotton 131, and avoiding the weakening of the aroma and sweetness of the smoke. The smoke blocking sheet 132 can be made of silica gel.

[0062] Further, the atomizer body 100 is provided with a circuit board 141, a battery 142, a microphone 143, and a charging interface 144. The microphone 143 is arranged in the air inlet channel 106, and can also be arranged in the air inlet channel 103. The microphone 143 functions as a trigger switch, and controls the working state of the atomizing core 30 according to the gas flow in the air channel. The battery 142, the microphone 143, the charging interface 144, the atomizing core 30, and the heating element 41 are electrically connected to the circuit board 141. The battery 142 is used to supply power to the microphone 143, the atomizing core 30, and the heating element 41. The circuit board 141 is used to control the normal working of the atomizing core 30 and the heating element 41. The charging interface 144 is used to charge the battery 142.

[0063] The circuit board 141 can control the working state of the atomizing core 30 and the heating element 41 according to the switch state of the switch mechanism. For example, when it is detected that the upper body 10 is rotated relative to the lower body 20 to the on position, the atomizer body 100 automatically starts the preheating mode, and the circuit board 141 controls the battery 142 to supply power to the heating element 41, so as to heat and melt the paste in the oil cup 40 to flow into the atomizing core 30. When the user inhales, the microphone 143 switch is triggered, and the atomizing core 30 starts to work, so as to heat the atomized tobacco tar to generate smoke for inhalation. When the atomizer body 100 is not used, the upper body 10 and the lower body 20 are rotated in the opposite direction. When it is detected that the upper body 10 is rotated relative to the lower body 20 to the off position, the circuit of the entire atomizer body 100 is disconnected, the first air inlet channel 103a and the second air inlet channel 103b are closed, and the first air inlet channel 106a and the second air inlet channel 106b are closed. At this time, the atomizer body 100 cannot be started.

[0064] Further, the upper body 10 is provided with a through hole 109 corresponding to the charging interface 144. The charging interface 144 is exposed from the through hole 109, so as to facilitate charging of the battery 142.

[0065] Further, the upper body 10 is provided with a first support 171, a second support 172, a first accommodating cavity 161 for accommodating the first support 171, and a second accommodating cavity 163 for accommodating the second support 172. The first accommodating cavity 161 and the second accommodating cavity 163 are arranged in the lower shell 16. The first support 171 is provided with a mounting hole 171a for mounting the oil cup 40, the heating element 41, the heat insulation cotton 42, and the atomizing core 30. The oil cup 40, the heating element 41, and the heat insulation cotton 42 are arranged in the upper part of the mounting hole 171a, and the atomizing core 30 is arranged in the lower part of the mounting hole 171a. The first support 171 and the second support 172 are made of silica gel.

[0066] Further, the lower shell 16 is provided with a mounting surface 164, and the circuit board 141 is mounted on the mounting surface 164, and the circuit board 141 is mounted in the second mounting groove 151 of the upper shell 15 together with the lower shell 16, so that the structure of the atomizer body 100 is more compact, and the volume of the atomizer body 100 is reduced, and the atomizer body 100 is convenient to carry.

[0067] In summary, the working principle of the entire electronic atomizer is as follows:

[0068] 1. The oil cup 40 of the atomizer body 100 is pre-stored with a paste medium (smoke paste);

[0069] 2. The atomizer body 100 is fixed on the filter container 200 containing the filtering liquid 210 (such as water), and one end of the air guide pipe 300 is inserted below the liquid surface 220;

[0070] 3. Rotate the upper body 10 and the lower body 20, when it is detected that the upper body 10 is rotated to the on position relative to the lower body 20, the circuit switch and the airway (air inlet 103, air inlet 106) of the entire electronic atomizer are opened, and the circuit board 141 controls the battery 142 to supply power to the heating element 41 outside the oil cup 40, so as to heat and melt the solid paste medium in the oil cup 40;

[0071] 4. After preheating, the user can open the suction nozzle cover 122, and suck from the suction nozzle 11. The microphone 143 detects the suction negative pressure, and the circuit board 141 controls the atomizer core 30 to start working to heat the liquid medium flowing into the atomizer core 30 from the oil cup 40, and mix with the air flowing into the air inlet 101 in the atomization cavity 102 to form a smoke that can be sucked;

[0072] 5. The smoke that can be sucked is transmitted to the bottom air guide pipe 300 in sequence through the first air inlet 103a, the first interface 103c, the third interface 103d, the second air inlet 103b and the air outlet 104, and is transmitted to below the liquid surface from the opening at the bottom of the air guide pipe 300;

[0073] 6. The gas coming out of the liquid is sucked by the user from the suction nozzle 11 in sequence through the air return port 105, the second air inlet 106b, the fourth interface 106d, the second interface 106c, the first air inlet 106a and the air inlet 107;

[0074] 7. After the suction is completed, the upper body 10 and the lower body 20 are reversely rotated, when it is detected that the upper body 10 is rotated to the closed position relative to the lower body 20, the circuit of the whole atomizer body 100 is disconnected, the first air inlet 103a and the second air inlet 103b are closed and conducted, and the first air inlet 103a and the second air inlet 103b are closed and conducted, at this time the atomizer body 100 cannot be started. Because the first air inlet 103a and the second air inlet 103b, and the first air inlet 103a and the second air inlet 103b are completely staggered, at this time even if the whole electronic atomizer is turned over, the liquid in the filter container 200 will not enter the inside of the atomizer body 100 through the airway (air inlet 103, air inlet 106), so as to avoid the electronic atomizer from being damaged by water in the scene of turning over or shaking.
