Description
Technical Field
[0001] The utility model relates to the technical field of electronic atomization devices, in particular to an electronic atomization device with a condensate recovery function. Background Art
[0002] An electronic atomizer is an electronic product that imitates cigarettes and has similar smoke, taste and feel to cigarettes. The electronic atomizer produces smoke by heating and atomizing the oil made of chemical substances and various flavorings, and controls the nicotine content by controlling the ingredients of the oil. Therefore, electronic cigarettes, which are mainly used for quitting smoking and replacing cigarettes, have been rapidly promoted and used.
[0003] In the related art, the electronic atomization device includes a main unit and a cigarette cartridge. The atomization core in the cigarette cartridge atomizes the cigarette oil through heating for the user to inhale. The smoke that is not completely inhaled will be in the smoke outlet channel. After contacting the inner wall of the smoke outlet channel, the smoke will condense into condensate on the inner wall of the smoke outlet channel, and the condensate will be stored in the condensation chamber at the bottom of the cigarette cartridge under the action of gravity. In addition, the stored cigarette oil also has the problem of leakage, and the leaked cigarette oil will also enter the condensation chamber due to gravity. However, due to the sealing reasons, the cigarette liquid in the condensation chamber is difficult to clean, and it is also easy to leak onto the main unit, affecting the operation of the electronic components in the main unit (such as the microphone and control panel, etc.).
[0004] Therefore, the prior art needs to be improved. Utility Model Content
[0005] In order to remedy the deficiencies of the prior art, the present application proposes an electronic atomization device with a condensate recovery function.
[0006] The utility model solves the technical problem by adopting the following technical solutions:
[0007] An electronic atomization device with a condensate recovery function comprises a main unit and a cigarette cartridge, wherein the main unit comprises a shell, the shell is provided with an installation cavity for installing the cigarette cartridge, a liquid storage pipe is provided in the shell, the liquid storage pipe is used to store condensate and cigarette oil, and a drainage hole is provided at the bottom of the cigarette cartridge, the drainage hole is connected to the liquid storage pipe.
[0008] By adopting the above technical solution, due to the setting of the liquid storage pipe and the drainage hole, when the smoke that has not been completely sucked out forms condensate on the inner wall of the smoke outlet channel, the condensate will slide downward under the action of gravity. When the condensate slides to the bottom of the cigarette cartridge, it can flow to the liquid storage pipe of the shell through the drainage hole set at the bottom of the cigarette cartridge for collection. At the same time, the smoke oil leaked from the atomization core of the cigarette cartridge will also flow into the liquid storage pipe, thereby minimizing the phenomenon that the condensate or smoke oil flows into the main unit and causes damage to the electronic components in the main unit.
[0009] Preferably, the liquid storage pipe is opened at one end away from the liquid discharge hole; a plugging head for plugging the opening of the liquid storage pipe is provided at the bottom of the shell, and the plugging head is detachably connected to the inner wall of the liquid storage pipe.
[0010] By adopting the above technical solution, due to the setting of the plugging head and the detachable connection between the plugging head and the inner wall of the liquid storage pipe, when the liquid in the liquid storage pipe is stored to a certain amount, the plugging head can be removed through the detachable connection between the plugging head and the liquid storage pipe to allow the liquid in the liquid storage pipe to flow out of the liquid storage pipe, thereby avoiding the overflow of liquid in the liquid storage pipe due to long-term use, thereby achieving the purpose of cleaning.
[0011] Preferably, a accommodating chamber is provided inside the cigarette cartridge, a bracket for installing an atomizer core is provided in the accommodating chamber, a side wall of the bracket is sealed and connected to the side wall of the accommodating chamber, a condensation chamber is formed between the bracket and the bottom of the accommodating chamber, the bracket is provided with through holes respectively connected to the condensation chamber and the air inlet end of the atomizer core, the drainage hole is connected to the condensation chamber, and the drainage hole is arranged opposite to the through hole, and an air inlet hole is provided at the bottom of the cigarette cartridge, and the air inlet hole is connected to the condensation chamber.
[0012] By adopting the above technical solution, since the drainage hole and the through hole are arranged opposite to each other, when the condensed liquid and the leaked smoke oil drip from the air inlet end of the atomizer core, they drip directly into the drainage hole as much as possible, which can avoid the accumulation of liquid in the condensation chamber and cause it to flow out from the air inlet hole.
[0013] Preferably, the air inlet is arranged in a trumpet shape, and the cross-sectional area of a side of the air inlet close to the condensation chamber is smaller than the cross-sectional area of a side away from the condensation chamber.
[0014] By adopting the above technical solution, since the air inlet hole is set in a trumpet shape and the cross-sectional area of the hole opening close to the condensation chamber is small, it is possible to avoid the liquid in the condensation chamber from flowing out of the air inlet hole as much as possible.
[0015] Preferably, a liquid blocking cylinder is provided in the condensation chamber, and the liquid blocking cylinder is communicated with the air inlet.
[0016] By adopting the above technical solution, due to the setting of the liquid blocking cylinder and the fact that the liquid blocking cylinder has a certain height, when condensate or smoke oil flows into the condensation chamber, the side wall of the liquid blocking cylinder will block the liquid, thereby preventing the liquid from flowing out of the air inlet hole as much as possible.
[0017] Preferably, the bottom of the condensation chamber is inclined toward the drainage hole.
[0018] By adopting the above technical solution, since the bottom of the condensation chamber is inclined toward the drain hole, when the liquid flows into the condensation chamber but not directly into the drain hole, the liquid will be at the bottom of the condensation chamber. Therefore, under the action of the inclined surface, the liquid will move toward the drain hole, so as much liquid in the condensation chamber as possible can be discharged into the liquid storage pipe.
[0019] Preferably, a connecting hole is provided on the shell, and an air intake passage which connects the air intake hole with the connecting hole is provided in the shell; an adjustment groove is provided on the shell, the bottom of the adjustment groove is connected with the connecting hole, an adjustment plate is slidably provided on the bottom of the adjustment groove, an adjustment hole is opened on the adjustment plate, and the adjustment plate is used to adjust the overlapping area between the adjustment hole and the connecting hole.
[0020] By adopting the above technical solution, due to the setting of the adjustment plate, when it is necessary to adjust the suction resistance of the electronic atomization device, the adjustment block is slid to change the position of the adjustment block in the adjustment groove, so that the overlapping area between the adjustment hole and the connecting hole can be changed, thereby achieving the purpose of changing the air intake amount of the atomization core and further achieving the purpose of changing the suction resistance of the electronic atomization device.
[0021] Preferably, a liquid pipette is provided in the liquid storage pipeline.
[0022] By adopting the above technical solution, since the electronic atomization device will tilt or shake to varying degrees when being carried, causing the liquid to flow out from the upper opening of the liquid storage pipe, the liquid suction rod is provided. Therefore, when the liquid enters the liquid storage pipe, the liquid will be absorbed by the liquid suction rod, thereby avoiding the liquid in the liquid storage pipe from flowing freely as much as possible.
[0023] Preferably, the side wall of the liquid storage pipe and the portion of the shell corresponding to the liquid storage pipe are made of transparent material.
[0024] By adopting the above technical solution, since the side walls of the liquid storage pipe and the corresponding parts of the shell are made of transparent materials, the liquid inventory in the liquid storage pipe can be observed in real time when the electronic atomization device is in use. When the liquid inventory in the liquid storage pipe reaches a certain value, the plugging head is removed through the detachable connection between the plugging head and the liquid storage pipe to release the liquid in the liquid storage pipe, thereby avoiding as much as possible the phenomenon that the liquid storage pipe is filled with liquid and overflows due to long-term use.
[0025] Preferably, a sealing gasket is provided at the bottom of the installation cavity, and the sealing gasket is provided with an avoidance gap corresponding to the air inlet channel and the liquid storage pipe. A sealing ring is provided on the sealing gasket, and the sealing ring is arranged around the upper opening of the liquid storage pipe. The sealing ring abuts against the bottom of the cigarette cartridge, and when the cigarette cartridge is installed in the installation cavity, the drainage hole at the bottom of the cigarette cartridge is in the sealing ring.
[0026] By adopting the above technical solution, due to the setting of the sealing gasket and the sealing ring, when the cigarette cartridge is installed in the installation cavity of the shell, the upper part of the sealing ring will abut against the bottom of the cigarette cartridge, so that the liquid storage pipe forms a sealed chamber, and only allows liquid to enter the liquid storage pipe from the drainage hole, which helps to prevent liquid from entering the inside of the host.
[0027] In summary, the present application includes at least one of the following beneficial technical effects:
[0028] 1. Due to the arrangement of the liquid storage pipe and the liquid drainage hole, when the smoke that has not been completely sucked out forms condensate on the inner wall of the smoke outlet channel, the condensate will slide downward under the action of gravity. When the condensate slides to the bottom of the cigarette cartridge, it can flow to the liquid storage pipe of the shell through the liquid drainage hole arranged at the bottom of the cigarette cartridge for collection. At the same time, the smoke oil leaked from the atomization core of the cigarette cartridge will also flow into the liquid storage pipe, thereby minimizing the phenomenon that the condensate or smoke oil flows into the host and causes damage to the electronic components in the host;
[0029] 2. Due to the setting of the plugging head and the detachable connection between the plugging head and the inner wall of the liquid storage pipe, when the liquid in the liquid storage pipe is stored to a certain amount, the plugging head can be removed through the detachable connection between the plugging head and the liquid storage pipe, so that the liquid in the liquid storage pipe can flow out of the liquid storage pipe, thereby avoiding the overflow of the liquid in the liquid storage pipe due to long-term use, thereby achieving the purpose of cleaning;
[0030] 3. Because the bottom of the condensation chamber is inclined toward the drain hole, when the liquid flows into the condensation chamber but not directly into the drain hole, the liquid will be at the bottom of the condensation chamber. Therefore, under the action of the inclined surface, the liquid will move toward the drain hole, so as much liquid in the condensation chamber as possible can be discharged into the liquid storage pipe.

DETAILED DESCRIPTION
[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0039] The present application embodiment discloses an electronic atomization device with a condensate recovery function. Figures 1 to 5The electronic atomization device includes a host 1 and a cartridge 2. Specifically, the host 1 includes a shell 11. The upper portion of the shell 11 is provided with an installation cavity 12 for installing the cartridge 2. A liquid storage pipe 13 is provided in the shell 11. The liquid storage pipe 13 is in a vertical posture as a whole, so that the liquid stored in the liquid storage pipe 13 can slide down to the lower end of the liquid storage pipe 13. The liquid storage pipe 13 is provided below the installation cavity 12. The cartridge 2 is used to be inserted into the installation cavity 12 of the shell 11. The cartridge 2 is provided with a receiving cavity in a hollow configuration. A liquid storage pipe 13 is provided at the upper portion of the cartridge 2. There is a smoke outlet channel, which is connected to the external atmosphere. A bracket 22 is arranged in the accommodating chamber 21. The bracket 22 is arranged at the lower side of the accommodating chamber 21. The peripheral side of the bracket 22 is sealed and abutted against the side wall of the accommodating chamber 21 to separate the accommodating chamber 21 into two chambers. The upper chamber is the oil storage chamber, and the lower chamber is the condensation chamber 23. The atomization core of the cigarette cartridge 2 is arranged in the oil storage chamber, and the air outlet end of the atomization core is sealed and connected to the smoke outlet channel. At the same time, a through hole 221 is arranged on the bracket 22. The cross section of the through hole 221 is circular when viewed from the direction of the hole on one side. The U-shaped air inlet end of the cartridge 2 is sealed and connected to the through hole 221. An air inlet hole 24 and a liquid discharge hole 25 are arranged at the bottom of the cartridge 2. The air inlet hole 24 is connected to the condensation chamber 23, and the liquid discharge hole 25 is also connected to the condensation chamber 23. The orifice cross-sectional area of the liquid discharge hole 25 is smaller than the cross-sectional area of the upper end opening of the liquid storage pipe 13. When the cartridge 2 is installed in the installation cavity 12, the liquid discharge hole 25 will be located directly above the upper end opening of the liquid storage pipe 13. Therefore, when the user uses the electronic atomization device, the smoke formed by the atomization of the smoke oil is not completely sucked out, and then under the action of air, the smoke is discharged. , will condense into condensate. Since there is less water and more smoke oil in the condensate, the water in the condensate in this embodiment can be ignored. The condensate will slide along the smoke outlet channel and the atomizer core into the condensation chamber 23 under the action of gravity. At the same time, the smoke oil leaked in the atomizer core will also slide together with the condensate, flow into the condensation chamber 23 through the through hole 221, and finally flow into the liquid storage pipe 13 through the drainage hole 25 for collection. In this way, it is possible to avoid the leakage of smoke oil or condensate from the smoke cartridge 2, which may cause damage to the electronic components in the host 1.
[0040] In order to facilitate the cleaning of the liquid in the liquid storage pipe 13, the side of the liquid storage pipe 13 away from the drain hole 25 is set to be an opening, and the liquid storage pipe 13 extends to the bottom of the shell 11 so that the lower end opening passes through the bottom of the shell 11, and a plugging head 3 is provided at the bottom of the shell 11. The plugging head 3 is used to seal the lower end opening of the liquid storage pipe 13, and the plugging head 3 is detachably connected to the side wall of the lower end of the liquid storage pipe 13. In this embodiment, the plugging head 3 is made of elastic material, and the detachable connection with the lower end opening of the liquid storage pipe 13 is achieved through the elastic deformation of the plugging head 3 itself. Therefore, after using the electronic atomization device for a long time, a certain amount of condensate and smoke oil will be stored in the liquid storage pipe 13, and the lower end opening of the liquid storage pipe 13 can be revealed by directly pulling out the plugging head 3, so that the liquid in the liquid storage pipe 13 can flow out of the liquid storage pipe 13, thereby achieving the purpose of cleaning.
[0041] In order to make the condensate and smoke oil dripping from the atomization core flow into the liquid storage pipe 13 better, the following settings are made accordingly. First, the drainage hole 25 at the bottom of the cigarette cartridge 2 is set opposite to the through hole 221 on the bracket 22, so that the condensate and smoke oil dripping from the through hole 221 will flow directly from the drainage hole 25 to the liquid storage pipe 13, so that they can drip into the drainage hole 25 as directly as possible, which can avoid the accumulation of liquid in the condensation chamber 23 and cause it to flow out from the air inlet 24; second, the lower wall of the condensation chamber 23 is inclined toward the drainage hole 25 at the part where the drainage hole 25 is located, so the liquid dripping on the bottom of the condensation chamber 23 and on the side of the drainage hole 25 will also move toward the drainage hole 25 under the action of the inclined surface, so as to discharge as much liquid in the condensation chamber 23 as possible into the liquid storage pipe 13.
[0042] In order to further prevent the liquid from flowing out of the air inlet 24 of the cigarette cartridge 2, the following settings are made accordingly. First, the air inlet 24 of the cigarette cartridge 2 can be set to be a trumpet shape (not shown in the figure), that is, the air inlet 24 has a small upper cross-sectional area and a large lower cross-sectional area. This design method is conducive to preventing the smoke liquid in the condensation chamber 23 from flowing out of the air inlet 24; second, a liquid blocking cylinder 4 is provided in the condensation chamber 23, and the liquid blocking cylinder 4 is penetrated by the air inlet 24 so that the liquid blocking cylinder 4 is annular as a whole. Since the liquid blocking cylinder 4 has a certain height, the liquid in the condensation chamber 23 can be blocked, so that the liquid in the condensation chamber 23 does not easily flow out of the air inlet 24, thereby minimizing the outflow of liquid from the cigarette cartridge 2.
[0043] In order to facilitate the adjustment of the suction resistance of the electronic atomization device, an air intake channel 15 is provided in the shell 11. One end of the air intake channel 15 passes through the bottom of the installation cavity 12, and the other end passes through the side wall of the shell 11 to form a connecting hole 14. At the same time, an adjusting groove 16 is provided on the side wall of the shell 11. The bottom of the adjusting groove 16 is connected with the connecting hole 14. An adjusting plate is provided at the bottom of the adjusting groove 16. The adjusting plate slides against the bottom of the adjusting groove 16 to block the connecting hole 14. An adjusting hole 51 is provided on the adjusting plate. During the sliding of the adjusting plate, the overlapping area between the adjusting hole 51 and the connecting hole 14 will change. Therefore, the air intake amount entering the air intake channel 15 from the connecting hole 14 can be changed, thereby changing the air intake amount of the atomization core, and then the suction resistance of the electronic atomization device can be changed, so that the electronic atomization device can be applied to a wider area.
[0044] A sealing gasket 6 is arranged at the bottom of the installation cavity 12. The sealing gasket 6 is made of silicone material. Notches corresponding to the air inlet channel 15, the liquid storage pipe 13 and the negative pressure channel are opened on the sealing gasket 6. A sealing ring 61 is arranged on the sealing gasket 6. The sealing ring 61 surrounds the upper end opening of the liquid storage pipe 13. At the same time, when the cigarette cartridge 2 is installed in the installation cavity 12, the discharge hole 25 at the bottom of the cigarette cartridge 2 is in the space surrounded by the sealing ring 61, and the sealing ring 61 abuts against the bottom of the cigarette cartridge 2, so that the liquid storage pipe 13 is not connected with the air inlet channel 15 and the negative pressure channel, so as to increase the sealing performance when the liquid storage pipe 13 is connected with the discharge hole 25. In addition, when the cigarette cartridge 2 is installed in the installation cavity 12, there is a certain gap between the bottom of the cigarette cartridge 2 and the sealing gasket 6, so that the air inlet channel 15 is connected with the negative pressure channel, and the microphone arranged at the other end of the negative pressure channel is used to control the start and stop of the electronic atomization device.
[0045] In this embodiment, in order to improve the functionality of the electronic atomization device, the side wall of the liquid storage pipe 13 and the part of the liquid storage pipe 13 corresponding to the shell 11 are made of transparent material, that is, the liquid storage pipe 13 and the corresponding part on the shell 11 are transparent, so that the user can observe the amount of liquid in the liquid storage pipe 13 conveniently, so that the user knows when the liquid in the liquid storage pipe 13 needs to be cleaned, and the phenomenon that the liquid storage pipe 13 is full and overflowing due to long-term cleaning can be avoided as much as possible; at the same time, a liquid absorption rod (not shown in the figure) can also be provided in the liquid storage pipe 13, the liquid absorption rod is a cotton swab, and is disposable, the liquid absorption rod is used to absorb condensed liquid and smoke oil, because the electronic atomization device will appear different degrees of tilt or shaking when being carried, so the liquid absorption rod can absorb the liquid to avoid the liquid from flowing freely and flowing out from the upper end opening of the liquid storage pipe 13 as much as possible.
[0046] The implementation principle of an electronic atomization device with a condensate recovery function in an embodiment of the present application is as follows: due to the arrangement of the drainage hole 25 and the liquid storage channel, the smoke oil and condensate leaked from the atomization core will drip from the drainage hole 25 into the liquid storage pipe 13 for collection, thereby minimizing the risk of liquid leakage affecting the operation of the electronic components in the host 1.
[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
