Description

Technical Field

[0001] The utility model relates to the technical field of atomizers, in particular to an atomizer structure without peculiar smell and oil leakage. Background Art

[0002] Traditional smoking is done by lighting tobacco with an open flame, which burns to produce smoke for smokers to inhale. The smoke produced by tobacco burning usually contains thousands of harmful substances. Therefore, traditional tobacco not only causes serious respiratory diseases to smokers, but also easily brings harm from secondhand smoke. In order to solve the technical problem of traditional tobacco burning producing more harmful substances such as tar, technicians have developed products such as atomizers and tobacco curing machines. It can simulate the appearance and taste of cigarettes, but does not contain harmful ingredients such as tar and suspended particles. This kind of electronic cigarette can be a substitute for cigarettes, helping people who have been smoking for a long time and have formed a smoking addiction.

[0003] The oil cup of the current atomizer usually uses a whole large piece of silicone to seal the bottom of the oil cup. The large silicone has a large size tolerance and is prone to large distortion during assembly, which will cause the sealing of the bottom of the oil cup to be poor, resulting in oil leakage at the bottom of the oil cup and causing the atomizer to have odor. In addition, the large silicone sealing design results in a small oil storage space at the bottom of the oil cup, causing the condensed smoke oil in the oil storage space to easily produce odor.

DETAILED DESCRIPTION

[0029] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0030] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0031] This embodiment relates to an atomizer structure without odor and oil leakage, such as Figure 1-7 As shown, it includes: an oil cup 100 and an atomization unit 200 .

[0032] Among them, the atomization unit 200 is arranged inside the oil cup 100, so that a smoke oil chamber 110 and a mist chamber 120 are formed inside the oil cup 100. The smoke oil chamber 110 is located on the peripheral side of the atomization unit 200, and is the area where the atomizer stores smoke oil. The smoke oil in the smoke oil chamber 110 can be transported to the atomization unit 200 for atomization by the atomization unit 200; the mist chamber 120 is located at the bottom of the atomization unit 200, and is connected to the inner cavity of the atomization unit 200. When the atomization unit 200 heats the atomized smoke oil, the generated smoke will fill the mist chamber 120, and the smoke oil that has not been atomized will flow into the mist chamber 120. After the atomizer stops working, the condensed waste oil will also flow into the mist chamber 120. An oil-absorbing cotton 300 is arranged in the mist chamber 120 to absorb the waste oil flowing into the mist chamber 120, so as to avoid the waste oil in the mist chamber 120 from generating odor and affecting the user experience. As a preferred solution, the oil-absorbing cotton 300 is arranged on the peripheral side of the mist storage chamber 120, which can effectively prevent the smoke flow inside the atomizer from passing through the oil-absorbing cotton 300, causing the oil-absorbing cotton 300 and the waste oil inside to produce odor, which is absorbed by the user and causes a bad user experience.

[0033] In this embodiment, the atomization unit 200 includes: a central tube 210 and a ceramic atomization core 220; the central tube 210 and the oil cup 100 are interference fit so that the upper end of the central tube 210 sealed and mortised at the inner center of the oil cup 100 is exposed for inhaling the smoke generated by the atomization unit 200, and a plurality of oil guide holes 211 connected to the smoke oil chamber 110 are evenly arranged on the circumference of the central tube 210, and the ceramic atomization core 220 is arranged at the inner side oil guide hole 211 of the central tube 210, so that the smoke oil in the smoke oil chamber 110 can be smoothly introduced into the ceramic atomization core 220, thereby achieving a good atomization effect. A circle of oil-guiding cotton 230 is also arranged between the oil-guiding hole 211 and the ceramic atomization core 220. The oil-guiding cotton 230 can first absorb the smoke oil, and then make the smoke oil evenly contact the surface of the ceramic atomization core 220, so that the smoke oil can be fully heated and atomized by the ceramic atomization core 220, thereby improving the atomization efficiency. At the same time, it can prevent the smoke oil from flowing directly into the mist storage chamber 120 without being atomized, causing the accumulation and waste of smoke oil.

[0034] The upper end of the oil cup 100 is designed with a large opening to facilitate the assembly of the atomization unit 200 inside the oil cup 100. The upper end of the oil cup 100 is provided with an upper sealing silicone 400 for sealing the upper end of the oil cup 100 to prevent the oil in the oil chamber 110 from leaking out. The upper sealing silicone 400 has a hole for exposing the upper end of the central tube 210 of the atomization unit 200, so as to absorb the smoke generated in the atomization unit 200. The central tube 210 and the upper sealing silicone 400 are interference-fitted to achieve a good seal between the central tube 210 and the upper sealing silicone 400, so as to prevent the oil in the oil chamber 110 from leaking out from between the central tube 210 and the upper sealing silicone 400, thereby wasting the oil and generating odor due to the oil leakage. In this embodiment, an upper sealing step 410 is provided on the inner circumference of the upper end of the oil cup 100, and the upper sealing silicone 400 is pressed and sealed with the upper sealing step 410, and the upper sealing step 410 is pressed and sealed with the top surface, bottom surface and side surface, so as to achieve the upper sealing silicone 400 to seal the upper end of the oil cup 100 in the horizontal direction and the vertical direction, and improve the sealing effect of the upper sealing silicone 400. As a preferred solution, an oil filling nail 500 is also pierced on the upper sealing silicone 400, and the oil filling nail 500 is connected to the smoke oil chamber 110 of the oil cup 100. The sealing of the oil cup 100 can be tested by pumping air into the smoke oil chamber 110 through the oil filling nail 500, and then smoke oil can be added into the smoke oil chamber 110 through the oil filling nail 500 to avoid the occurrence of oil leakage in the smoke oil chamber 110.

[0035] The lower end of the oil cup 100 is a bottom structure, and the design of not using a large silicone bottom seal can avoid the problem of poor sealing of the bottom of the oil cup 100 and leakage of waste oil from the bottom of the mist chamber 120 due to the tolerance of the large silicone and the distortion during assembly. At the same time, the internal space of the mist chamber 120 is larger, which can accommodate more smoke oil. A larger oil-absorbing cotton 300 can be set inside the mist chamber 120 to avoid wasting oil and generating odor in the mist chamber 120.

[0036] In this embodiment, an air inlet hole 130 is provided in the middle of the bottom of the oil cup 100, and an air inlet pipe 600 is provided inside the air inlet hole 130 to realize the air intake atomization of the atomization unit 200 and achieve a good atomization effect. A lower sealing silicone 700 is provided between the air inlet pipe 600 and the air inlet hole 130 to realize the dedicated fixing of the air inlet pipe 600 and the sealing between the air inlet pipe 600 and the air inlet hole 130, so as to prevent the waste oil in the mist storage chamber 120 from leaking from between the air inlet pipe 600 and the air inlet hole 130, thereby causing the atomizer to produce odor. As a preferred solution, the thickness of the lower sealing silicone 700 is 0.5 mm, and the distortion and deformation of the sealing silicone during installation is small, thereby ensuring the sealing effect at the lower sealing silicone 700. Of course, in other implementations, the thickness of the lower sealing silicone 700 can also be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, etc. to achieve a good sealing effect.

[0037] As a preferred solution, a lower sealing step 710 is provided on the inner peripheral side of the lower end of the air inlet hole 130, and the outer side of the lower sealing silicone 700 is pressed and sealed with the lower sealing step 710, so that the outer side of the lower sealing silicone 700 is pressed and sealed with the bottom and side surfaces of the lower sealing step 710, which can achieve the sealing cooperation of the upper and lower sealing silicone 700 with the air inlet hole 130 in the horizontal direction and the vertical direction, thereby improving the sealing effect of the lower sealing silicone 700.

[0038] In this embodiment, an oil absorption chamber 310 for accommodating the oil absorption cotton 300 is provided on the peripheral side of the mist storage chamber 120, and an installation window 320 for placing the oil absorption cotton 300 is provided on the side wall of the oil cup 100 and the outer side of the oil absorption chamber 310, so that the oil absorption cotton 300 can be installed in the oil absorption chamber 310 to achieve a good oil absorption effect. A sealing cover 800 is fixedly provided on the installation window 320 to seal the installation window 320 to prevent the waste oil in the mist storage chamber 120 and the waste oil in the oil absorption cotton 300 from leaking from the installation window 320, causing the atomizer to produce odor. The oil absorption chamber 310 is provided on the peripheral side of the mist storage chamber 120, and a larger space can be provided to accommodate the larger volume of the oil absorption cotton 300, so as to achieve a better oil absorption effect, and it can prevent the airflow inside the atomizer from excessively contacting the oil absorption cotton 300, causing the generation of odor when absorbing smoke. As a preferred solution, the sealing cover 800 and the installation window 320 are sealed and fixed by double ultrasonic line double groove welding to ensure the sealing performance of the sealing cover 800 and the installation window 320 and prevent waste oil from leaking from the installation window 320.

[0039] In this embodiment, a blocking wall 900 is provided between the oil absorption chamber 310 and the mist chamber 120 to block the middle and upper parts of the oil absorption cotton 300, reduce the connection area between the oil absorption cotton 300 and the mist chamber 120, thereby preventing the atomized airflow from contacting the oil absorption cotton 300 over a large area when flowing through the mist chamber 120, so as to bring out the odor of the oil absorption cotton 300, resulting in a bad user experience. As a preferred solution, the bottom of the mist chamber 120 is tilted toward the oil absorption chamber 310, and the side of the bottom of the mist chamber 120 away from the oil absorption chamber 310 is higher than the side close to the oil absorption chamber 310, so that the waste oil at the bottom of the mist chamber 120 can flow into the oil absorption chamber 310 and be absorbed by the oil absorption cotton 300, achieving a good oil absorption effect, and the waste oil will not accumulate at the bottom of the mist chamber 120, further preventing the waste oil from leaking from the lower sealing silica gel 700.

[0040] The above is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
