[0038] The present invention will be further described below with reference to the accompanying drawings and examples.

[0039] refer to Figure 1 and Figure 2The first embodiment of the present invention provides an oil seal, primarily used in electronic atomization devices, to prevent leakage of atomized oil. The oil seal comprises a seal body 1, which includes a first end 2 and a second end 3. A plurality of annular sealing teeth 4 are provided along the axial direction of the first end 2 of the seal body 1, with an oil storage space 5 formed between adjacent sealing teeth 4 for storing atomized oil. The depth H of the oil storage space 5 gradually decreases from the first end 2 to the second end 3 of the seal body 1. Through this structure, in actual application, the leaked atomized oil will first flow to the first oil storage space 5, that is, the oil storage space 5 close to the end face of the first end 2 of the seal body 1, and then overflow to the next oil storage space 5 after the first oil storage space 5 is filled, until all the oil storage spaces 5 are filled. In this process, the multiple oil storage spaces 5 with depths H from deep to shallow can store the leaked atomized oil and make it more difficult for the atomized oil to flow. Compared with traditional seals with smooth outer surfaces and no oil storage space, this seal can prevent the leakage of atomized oil and has a good sealing effect. Even if a small amount of atomized oil leaks, the multiple oil storage spaces 5 with depths H from deep to shallow can also prolong the time for the atomized oil to leak.

[0040] It can be understood that a plurality of annular sealing teeth 4 may be arranged at intervals along the axial direction of the seal body 1 on the outer periphery of the second end 3 of the seal body 1, and the depth of the oil storage space 5 gradually decreases from the second end 3 to the first end 1 of the seal body 1.

[0041] The maximum outer diameter of several sealing teeth 4 is larger than the outer diameter of the sealing body 1, so that when the sealing body 1 is assembled into the channel to be sealed (the sealing body 1 is generally interference fit with the channel to be sealed during actual assembly), several sealing teeth 4 are squeezed by the inner wall of the channel to be sealed, and the tooth tip of the previous sealing tooth 4 is directed toward the next sealing tooth 4, so that a relatively closed oil storage space 5 can be formed between the previous sealing tooth 4 and the next sealing tooth 4, so that the atomized oil is not easy to flow out of the oil storage space 5.

[0042] The cross-sectional shape of the oil storage space 5 is an inverted trapezoid. It is understandable that the cross-sectional shape of the oil storage space 5 can also be a rectangle. The cross-sectional shape and number of the oil storage space 5 can be set according to actual conditions.

[0043] An annular oil storage recess 6 is provided at the bottom of the oil storage space 5 for further storing the atomized oil, thereby further preventing the atomized oil from leaking out and further prolonging the time for the atomized oil to leak out.

[0044] The minimum width of the oil storage space is 0.08-0.11 mm, preferably 0.1 mm, so that more sealing teeth 4 can be provided on the periphery of the first end 2 or the periphery of the second end 3 of the seal body 1 .

[0045] The seal body 1 is made of a hard plastic material, such as hard PVC (polyvinyl chloride) or PS (polystyrene). Hard plastic oil seals can be used in small electronic atomization devices. When the seal body 1 is used in large electronic atomization devices, the seal body 1 can also be made of a soft plastic material, such as PP (polypropylene) or PE (polyethylene).

[0046] The sealing body 1 is columnar, preferably cylindrical. When actually applied to the channel to be sealed of the electronic atomization device to achieve sealing, the sealing step includes: squeezing one end of the sealing body 1 with a plurality of annular sealing teeth 4 spaced apart from each other from the far oil leakage end of the channel to be sealed into the channel to be sealed, so that the one end of the sealing body 1 with a plurality of annular sealing teeth 4 spaced apart from each other is located at the oil leakage end of the channel to be sealed. During the squeezing process, under the action of the squeezing force, the tooth tip of the previous sealing tooth 4 will face the next sealing tooth 4, so that a relatively closed oil storage space 5 can be formed between the previous sealing tooth 4 and the next sealing tooth 4, so that the sealing of the channel to be sealed can be achieved. It can be understood that the sealing body 1 can also be screwed into the channel to be sealed. In this way, the tooth tip of the previous sealing tooth 4 of the sealing body 1 will also face the next sealing tooth 4.

[0047] Figure 3 This is a cross-sectional diagram of an oil seal applied to the battery rod of an electronic atomizer device. The oil seal is assembled within the battery rod housing 8a, located at one end of the battery 9, to seal the battery 9 and prevent damage. The first end 2 of the seal body 1 is positioned adjacent to the opening of the housing 8a. Several sealing teeth 4, as described above, are provided around the outer periphery of the first end 2 of the seal body 1 to achieve a seal.

[0048] refer to Figure 4 The second embodiment of the present invention provides an oil-sealing seal. Unlike the first embodiment, the seal body 1 includes a first sealing portion 1a, a connecting portion 1b, and a second sealing portion 1c connected in sequence. The outer diameters of the first sealing portion 1a and the second sealing portion 1c are equal and larger than the outer diameter of the connecting portion 1b. The plurality of sealing teeth 4 are arranged at intervals along the axial direction of the seal body 1 on the outer periphery of the first end 2a of the first sealing portion 1a. The depth of the oil storage space 5 gradually decreases from the first end 2a to the second end 2b of the first sealing portion 1a. It can be understood that the plurality of sealing teeth 4 are arranged at intervals along the axial direction of the seal body 1 on the outer periphery of the second end 3b of the second sealing portion 1c, and the depth of the oil storage space 5 gradually decreases from the second end 3b to the first end 3a of the second sealing portion 1c. The first sealing portion 1a, the connecting portion 1b, and the second sealing portion 1c are preferably integrally formed.

[0049] refer to Figure 5The third embodiment of the present invention provides an oil-sealing seal, which differs from the first embodiment in that the seal body 1 includes a first sealing portion 1d and a second sealing portion 1e connected together. The outer diameter of the first sealing portion 1d is smaller than the outer diameter of the second sealing portion 1e. The plurality of sealing teeth 4 are arranged at intervals along the axial direction of the seal body 1 on the outer periphery of the first end 2c of the first sealing portion 1d and the outer periphery of the first end 3c of the second sealing portion 1e. The depth of the oil storage space 4 of the first sealing portion 1d gradually decreases from the first end 2c to the second end of the first sealing portion 1d, and the depth of the oil storage space 4 of the second sealing portion 1e gradually decreases from the first end 3c to the second end 3d of the second sealing portion 1e.

[0050] Figure 6 、 Figure 7 This is a cross-sectional diagram of the oil seal applied to the upper silicone member 8b and the lower silicone member 8c of the atomizer. The upper silicone member 8b is generally applied to the upper end of the oil cup of the atomizer, and the lower silicone member 8c is generally applied to the lower end of the oil cup of the atomizer. The entire oil seal is assembled into the upper silicone member 8b and the lower silicone member 8c. The plurality of sealing teeth 4 on the outer periphery of the first end 3c of the second sealing portion 1e are used to achieve sealing at one end of the upper silicone member 8b and the lower silicone member 8c. Figure 7 In the embodiment, based on assembly requirements, a boss 3e is formed on the outer periphery of the second end 3d of the second sealing portion 1e to seal the assembly of the oil seal and the lower silicone member 8c.

[0051] Figure 8 This is a cross-sectional diagram of an oil seal applied to the vent tube 8d of an atomizer. The vent tube is typically connected between the atomizer's nozzle and atomizer core. A first sealing portion 1d is assembled to the corresponding end of the vent tube 8d. Several sealing teeth 4, located around the first end 2c of the first sealing portion 1d, seal the corresponding end of the vent tube 8d. It is understood that the oil seal may be structurally modified to facilitate better integration with other components.

[0052] refer to Figures 9 to 11 The present invention provides an electronic atomization device, including an atomizer and a battery rod connected to the atomizer, and the battery rod is used to power the atomizer. The atomizer includes an oil cup 10, an electrode base 20 installed at one end of the oil cup 10, an atomizing core 30 installed in the oil cup 10, and an atomizing base 50 installed in the oil cup 10. A protective cover 40 is installed at the end of the oil cup 10 where the electrode base 20 is installed, and the electrode base 20 is accommodated in the protective cover 40, thereby protecting the electrode base 20. The end of the oil cup 10 away from the electrode base 20 has an air intake 11 for the user to inhale. An air intake pipe 12 is formed at the edge position on the inner side of the air intake 11, and the air intake pipe 12 is located in the oil cup 10.

[0053] The atomizer core 30 includes an atomizer tube 31 and a ceramic heating element 32 installed in the atomizer tube 31. The first end of the atomizer tube 31 is installed in the upper end of the atomizer base 50. The second end of the atomizer tube 31 is connected to the intake pipe 12 through a connector 33. The connector 33 is a leak-proof silicone member. Specifically, the two ends of the connector 33 each have an installation groove, and the second end of the atomizer tube 31 and the end of the intake pipe 12 are respectively installed in the corresponding installation grooves. The connector 33 has an air passage 331 connecting the intake pipe 12 and the atomizer tube 31, so that the gas heated and atomized by the heating element 32 can enter the air passage 331 from the second end of the atomizer tube 31, and then enter the intake pipe 12 through the air passage 331, and finally be inhaled by the user at the intake port 11. An oil storage chamber 13 is formed between the outer side of the atomizer tube 31 and the inner wall of the oil cup 10 for storing atomized oil.

[0054] The lower end of the atomizer base 50 is installed in the electrode base 20. At least one side of the upper end of the atomizer base 50 is provided with an oil inlet channel 52 connected to the oil storage chamber 13. The first end of the atomizer tube 31 has an oil inlet hole 311 connected to the oil inlet channel 52. The atomizer base 50 has a separation channel 53 running through it from the upper end to the lower end. The separation channel 53 intersects with the oil inlet channel 52 and divides the oil inlet channel 52 into a first part 521 connected to the oil storage chamber 13 and a second part 522 connected to the oil inlet hole 311. In this embodiment, the separation channel 53 and the oil inlet channel 52 are preferably orthogonal. The electrode base 20 has a through hole 21 connected to the separation channel 53. The protective cover 40 has a protective cover through hole 41 connected to the through hole 21.

[0055] Furthermore, at least one side of the upper end of the atomizing base 50 has a slot 511 (see Figure 11 ), an oil inlet space 51 is formed between the groove 511 and the inner wall of the oil cup 10, and the oil inlet channel 52 is arranged at the bottom of the groove 511 and communicates with the oil storage chamber 13 through the oil inlet space 51.

[0056] In this embodiment, the upper end surface of the atomizing base 50 is provided with a mounting position 54 (see Figure 11), the first end of the atomizing tube 31 is installed in the mounting position 54. At least two sealing rings 312 and 313 are provided between the inner wall of the mounting position 54 and the first end of the atomizing tube 31. Among the at least two sealing rings 312 and 313, one sealing ring 312 is located above the oil inlet hole 311 to prevent the atomized oil in the oil storage chamber 13 from entering the mounting position 54, and the other sealing ring 313 is located below the oil inlet hole 311 to prevent the atomized oil entering the oil inlet hole 311 from entering the mounting position 54. In this way, the atomized oil can be prevented from leaking from the air inlet channel of the electrode base 20 and the protective cover 40. In this embodiment, there is one sealing ring 312 located above the oil inlet hole 311, and two sealing rings 313 located below the oil inlet hole 311. It can be understood that the number of sealing rings 312 and 313 located above and below the oil inlet hole 311 can be other numbers.

[0057] The partition channel 53 is provided with Figure 4 The oil seal shown is movable within the partition channel 53 along the axial direction of the partition channel 53. It is used to block or open the connection between the first portion 521 and the second portion 522 and to prevent the atomized oil in the oil reservoir 13 from leaking out of the partition channel 53. The seal body 1 of the oil seal forms an interference fit with the partition channel 53. The seal body 1 is made of hard rubber.

[0058] The first sealing portion 1a and the second sealing portion 1c are respectively located at the two ends of the partition channel 53, and the first sealing portion 1a is located between the first portion 521 and the second portion 522, thereby blocking the communication between the first portion 521 and the second portion 522. In this way, the atomized oil in the oil storage chamber 13 can be prevented from entering the oil inlet hole 311 through the oil inlet channel 52, thereby isolating the atomized oil and the atomizer core 30. Even if the atomizer is transported, carried or stored for a long time, the atomized oil will not enter the oil inlet hole 311, so that the heating element 32 will not accumulate atomized oil and oil leakage will not occur. Therefore, the user will have a better smoking experience when using it for the first time.

[0059] The first sealing portion 1a is located between the first portion 521 and the second portion 522. The plurality of oil storage spaces 5 around the first end 2a of the first sealing portion 1a store atomized oil flowing from the oil storage cavity 13 into the partition channel 53. This seal also prevents the atomized oil from leaking out of the partition channel 53, thereby sealing the partition channel 53. The oil storage recess 6 at the bottom of the oil storage space 5 further prevents the atomized oil from leaking out of the partition channel 53.

[0060] The second sealing portion 1 c is used to seal the distal oil storage cavity end of the separation channel 53 , thereby preventing water, dust, etc. from entering the separation channel 53 through the protective cover through-holes 41 and 21 .

[0061] When the user uses the device for the first time, the oil sealing member can be moved along the partition channel 53 to a position where the communication portion 1b is located between the first portion 521 and the second portion 522. Figure 12 As shown, the connecting portion 1b can open the connection between the first part 521 and the second part 522. At this time, the atomized oil in the oil storage chamber 13 can enter the oil inlet hole 311 through the oil inlet channel 52 and enter the heating element 32, thereby being heated by the heating element 32 and atomized into gas. The oil seal is moved to the position where the connecting portion 1b is located between the first part 521 and the second part 522. This can be done using other auxiliary tools equipped with the atomizer, such as a tubular object. Specifically, one end of the tubular object is inserted into the through hole 21 from the protective sleeve through hole 41, and the oil seal is pushed upward with force until the connecting portion 1b of the oil seal is located between the first part 521 and the second part 522. At this time, the user can use it. To facilitate user observation, the oil cup 10 and the atomizer base 50 can be set to be transparent. When the first sealing portion 1a of the oil seal is almost completely located in the oil storage chamber 13, the oil seal can be stopped from being pushed. At this time, the atomizer is ready for use. When the first sealing portion 1 a is located in the oil storage chamber 13 , the atomized oil in the oil storage chamber 13 can also enter the second portion 522 from the partition channel 53 .

[0062] In this embodiment, the outer diameters of the first and second sealing portions 1a and 1c are larger than the inner diameter of the partition channel 53, thereby blocking the connection between the first portion 521 and the second portion 522 and sealing the partition channel 53. The outer diameters of the first and second sealing portions 1a and 1c are preferably equal. The outer diameter of the connecting portion 1b is smaller than the inner diameter of the partition channel 53, thereby opening the connection between the first and second portions 521 and 522. The lengths of the first, second, and connecting portions 1a and 1c are all greater than the inner diameter of the oil inlet channel 52, enabling the first and second sealing portions 1a and 1b to block or open the oil inlet channel when located between the first and second portions 521 and 522, respectively.

[0063] In this embodiment, two oil inlet channels 52 are provided on either side of the upper end of the atomizer base 50, each communicating with the oil storage chamber 13. This means there are two oil inlet channels 52, which can increase the amount of oil inlet. Therefore, a groove 51 is provided on either side of the upper end of the atomizer base 50, and the atomizer base 50 has two separating channels 53, which are located on either side of the atomizer base 50. The first end of the atomizer tube 31 has an oil inlet hole 311, each communicating with the two oil inlet channels 52. There are also two oil sealing seals. That is, the number of oil inlet channels 52, separating channels 53, oil inlet holes 311, and oil sealing seals is the same.

[0064] In other embodiments, the number of the oil inlet channel 52 , the partition channel 53 , the oil inlet hole 311 and the oil sealing member may be, for example, three or four or more, and may be set according to actual conditions.

[0065] In an alternative solution to the oil seal, Figure 13 As shown, the oil seal is based on Figure 1 The oil seal shown is Figure 1 The seal body 1 shown is provided with a through-hole 7 for connecting the first and second parts 521, 522. The through-hole 7 is located below the first and second parts 521, 522, thereby blocking the connection between them and preventing the atomized oil in the oil reservoir 13 from leaking out of the partition channel 53. During initial use, the oil seal can be moved to a position where the through-hole 7 is located between the first and second parts 521, 522. This allows the connecting portion 1b to open the connection between the first and second parts 521, 522 through the through-hole 7, thereby allowing the atomized oil in the oil reservoir 13 to enter the oil inlet hole 311 through the oil inlet channel 52 and ultimately into the heating element 32. In actual use, the oil seal can also be pushed upward using the tubular member until the through-hole 7 of the connecting portion 1b is located between the first and second parts 521, 522. The oil cup 10 and atomizer base 50 can be made transparent to facilitate observation of the movement position.

[0066] The inner diameter of the through hole 21 of the electrode base 20 is smaller than the inner diameter of the partition channel 53, thereby limiting the movement of the oil sealing seal. That is, the oil sealing seal can only be pushed upward to make the connecting portion 1b of the oil sealing seal located between the first part 521 and the second part 522, but the oil sealing seal cannot be pulled downward.

[0067] The above embodiments merely represent preferred implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art will be able to make various modifications and improvements without departing from the spirit of the present invention, such as combining different features from the various embodiments, and all such modifications and improvements fall within the scope of protection of the present invention.
