DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It will be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some, rather than all, structures related to the present application are shown in the drawings. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0039] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0040] Existing products have the problem of liquid leaking from the atomizer core directly dripping outside the atomizer device.

[0041] In this application, the projection of the air inlet is located outside the projection of the atomizer core along the length of the atomizer device, that is, the air inlet and the atomizer core are staggered. In this way, the dripping and leakage of the atomizer core can be blocked by the bottom cover, preventing the leakage from directly falling out of the shell.

[0042] Figure 1 is a cross-sectional view of an embodiment provided by this application, Figure 2 It is an exploded view of an embodiment provided by this application.

[0043] The present application provides an atomization device 100 , which includes a housing 10 , an atomization core 20 , a sealing member 30 and a bottom cover 40 .

[0044] The bottom cover 40 is disposed at the bottom of the housing 10 and encloses the housing 10 to form a receiving space.

[0045] The sealing member 30 is disposed in the accommodating space and encloses the housing 10 to form a liquid storage chamber 110 . The atomizer core 20 is disposed in the liquid storage chamber 110 .

[0046] The atomizing device 100 includes a longitudinal direction (such as Figure 1 As shown in a), the bottom cover 40 is provided with at least one air inlet hole 410 . In the length direction of the atomizing device 100 , the projection of the air inlet hole 410 is located outside the projection of the atomizing core 20 .

[0047] Among them, see Figure 1 and Figure 2 The middle of the housing 10 is a cavity, see Figure 1In this embodiment, the top of the cavity is closed and the bottom is open. The housing 10 is provided with a nozzle airway 111 extending along the axial direction of the housing 10 (i.e., the aforementioned longitudinal direction). The top of the nozzle airway 111 passes through the shell wall at the top of the cavity to connect to the outside of the housing 10, while the bottom is disposed within the cavity. The atomizer core 20 is disposed within the cavity and connected to the bottom of the nozzle airway 111.

[0048] See also Figure 4 and Figure 5 The seal 30 can be a silicone seat. The outer contour of the seal 30 is adapted to the inner wall of the cavity. After the seal 30 is tightly fitted into the cavity, the portion of the cavity above the seal 30 forms a liquid storage chamber 110. According to the prior art, the atomizer core 20 is located in the liquid storage chamber 110, and the atomizer core 20 can absorb the atomized matrix in the liquid storage chamber 110. In addition, an oil filling hole is provided on the shell wall of the shell 10 corresponding to the liquid storage chamber 110. The oil filling hole is used to directly fill oil into the liquid storage chamber 110 from the outside, and then the oil filling hole is sealed by a rubber plug.

[0049] Bottom cover 40, see Figure 6 and Figure 7 , which can be selected as a plastic seat. Similarly, the bottom cover 40 is adapted to the inner wall of the cavity, so the bottom cover 40 seals the bottom end of the cavity.

[0050] The bottom cover 40 is provided with at least one air inlet hole 410. The number of air inlet holes 410 can be selected as needed. In this embodiment, two embodiments are taken as examples. It can be seen that the atomizer core 20 is usually arranged in the middle of the cavity, and the air inlet hole 410 can be arranged near the edge of the bottom cover 40. The key point is that in the longitudinal direction of the atomizer device 100, the projection of the air inlet hole 410 is located outside the projection of the atomizer core 20. That is, see Figure 1 In the axial direction of the shell 10, the air inlet hole 410 and the atomizer core 20 are staggered so that their projections do not cross and overlap.

[0051] by Figure 1 To illustrate the usage status, the liquid storage chamber 110 is first injected with an atomizing matrix. After the atomizing matrix flows to the atomizing core 20 and is atomized, the mist is discharged from the housing 10 to the top of the nozzle airway 111. If the atomizing core 20 leaks at this time, the leaked liquid will drip down onto the top surface of the bottom cover 40. As mentioned above, the air inlet 410 and the atomizing core 20 are staggered, so the leaked liquid will not drip from the air inlet 410 to the outside of the housing 10.

[0052] In addition, to prevent the leaked liquid dripping onto the bottom cover 40 from flowing into the air inlet hole 410 , a shielding convex ring can be provided around the inner end of the air inlet hole 410 , thereby preventing the leaked liquid from flowing into the air inlet hole 410 .

[0053] Optionally, in the length direction, the bottom cover 40 is disposed at the bottom of the sealing member 30 .

[0054] The shell 10 is formed with a nozzle airway 111, which passes through the liquid storage chamber 110 and is connected to the outside of the shell 10. The atomizer core 20 is provided with an atomization airway, and the seal 30 is provided with a vent. The nozzle airway 111, the atomization airway and the vent are connected in sequence.

[0055] The sealing member 30 is provided with at least one air inlet channel 310 , one end of the air inlet channel 310 is connected to the vent hole, and the other end is connected to the air inlet hole 410 .

[0056] In the aforementioned embodiment, a relatively large gap may exist between the bottom cover 40 and the seal 30, and the gap may be used as a channel for external air to flow to the vent hole of the seal 30 after entering the housing 10 from the air inlet hole 410. In this embodiment, in order to maximize the compactness of the spatial positions of the various components of the atomizing device 100 and thereby reduce the overall volume of the atomizing device 100, the top of the bottom cover 40 is as close as possible to the bottom of the seal 30, or even directly abuts against the bottom of the seal 30. In order to ensure that external gas can flow smoothly to the vent hole of the seal 30 after entering the accommodation space, an air inlet channel 310 may be provided in the seal 30. This can be achieved by providing the air inlet channel 310 inside the seal 30. Importantly, one end of the air inlet channel 310 is connected to the vent hole of the seal 30, and the other end is provided directly above the air inlet hole 410, so that the air entering from the air inlet hole 410 can flow into the air inlet channel 310 unobstructed. See. Figure 3 The air in the air inlet channel 310 directly flows into the vent hole of the seal 30, so the air passes through the seal 30, the atomizer core 20 and the nozzle air channel 111 in sequence, and is finally discharged outside the housing 10. It should be noted that two air inlet channels 310 should be provided correspondingly to the two air inlet holes 410.

[0057] It should be noted that the middle portion of the atomizer core 20 provides a heat source to atomize the atomized matrix, thereby forming an atomizing channel in the middle portion of the atomizer core 20 in the axial direction, the top of which is connected to the mouthpiece airway 111. The middle portion of the seal 30 is provided with an air vent in the axial direction, the top of which is connected to the bottom of the atomizing channel. In this way, from bottom to top, the air inlet hole 410, the air inlet channel 310, the air vent, the atomizing airway, and the mouthpiece airway 111 form a complete airflow path.

[0058] Optional, see Figure 5 The air inlet passage 310 is provided on the bottom surface of the sealing member 30 close to the bottom cover 40 .

[0059] It is known that if the air inlet channel 310 is arranged from the inside of the sealing member 30, the air inlet channel 310 will not be easy to process. Therefore, in this embodiment, the air inlet channel 310 is directly arranged on the bottom surface of the sealing member 30, and the bottom side of the air inlet channel 310 is directly open, which makes it easier to form the air inlet channel 310.

[0060] Optionally, in combination with the above, the atomization device 100 further includes a liquid absorbing member 50 , which is disposed between the sealing member 30 and the bottom cover 40 .

[0061] The absorbent element 50 can be made of absorbent cotton or foam. It should be noted that the absorbent element 50 can be directly mounted on the bottom cover 40, and the larger the absorbent element 50, the better. A larger volume can absorb more leaked liquid. Importantly, along the length of the atomizing device 100 (i.e., in the axial direction of the housing 10), the absorbent element 50 is provided with a clearance hole corresponding to the air inlet 410 to prevent it from obstructing the air inlet 410.

[0062] See also Figure 4 Optionally, at least one first sealing protrusion 330 is provided on the outer side wall of the sealing member 30 .

[0063] When the sealing member 30 is disposed in the housing 10 , the first sealing protrusion 330 is used to seal the gap between the outer wall of the sealing member 30 and the inner wall of the housing 10 .

[0064] The cross section of the first sealing protrusion 330 is an arc-shaped profile, and the first sealing protrusion 330 forms a circle along the outer wall of the sealing member 30. The number of the first sealing protrusion 330 can be one or more, and multiple first sealing protrusions 330 are arranged in parallel up and down along the axial direction of the shell 10.

[0065] In particular, the first sealing protrusion 330 is used to seal the gap between the outer wall of the seal 30 and the inner wall of the shell 10, and this gap is directly connected to the liquid storage chamber 110, so leakage may be involved. In this embodiment, at least two first sealing protrusions 330 can be provided.

[0066] Optional, see Figure 6 , the bottom cover 40 is provided with an inserting portion 41, and the sealing member 30 includes a main body portion and a boss portion;

[0067] When the bottom cover 40 is plugged into the bottom of the housing 10 , the plug-in portion 41 is disposed around the periphery of the boss portion.

[0068] The main body, the upper portion, conforms to the inner contour of the housing 10. The aforementioned first sealing protrusion 330 is located on the outer wall of the main body. The platform portion is located at the bottom of the main body. The platform portion can be understood as being scaled down proportionally to the main body portion, forming an annular step between the outer walls of the platform and the main body. When the bottom cover 40 is sealed against the bottom of the housing 10, the cylinder is inserted into the annular step to enclose the platform portion, and the outer wall of the cylinder is in close contact with the inner wall of the housing 10.

[0069] In addition, the bottom cover 40 is provided with an insertion groove 420 . In the length direction of the atomizing device 100 , a protrusion 120 is provided at the bottom end of the shell 10 . When the bottom cover 40 is sealed at the bottom of the shell 10 , the protrusion 120 is inserted into the insertion groove 420 .

[0070] Secondly, the raised member 120 can be a raised block or a raised ring. An annular raised ring is provided around the circumference of the sealing member 30. The top of the annular raised ring is provided with a plug-in groove 420 (which is adapted to the raised member 120). When the bottom cover 40 is sealed against the bottom of the housing 10, the plug-in groove 420 is sleeved on the raised member 120, thus forming a stepped seal on the bottom wall of the housing 10. In addition, the outer wall of the annular raised ring is flush with the outer wall of the housing 10 to improve the overall appearance.

[0071] See also Figure 4 Optionally, at least one second sealing protrusion 321 is provided on the side wall of the boss portion, and the second sealing protrusion 321 acts on the gap between the sealing plug-in portion 41 and the boss portion.

[0072] The second sealing protrusions 321 have an arcuate cross-section and are arranged in a circle along the annular sidewall. The number of second sealing protrusions 321 can be one or more, with multiple second sealing protrusions 321 arranged in parallel vertically along the axial direction of the housing 10. The second sealing protrusions 321 fill the gap between the plug portion 41 and the plugging position 320, thereby improving the tightness of the plug-in connection between the two.

[0073] In addition, at least one buckle can be provided on each of the two opposite outer walls of the plug-in portion 41, and a corresponding buckle can be provided on the side wall of the shell 10. When the plug-in portion 41 is plugged into the shell 10, one buckle can be correspondingly buckled with one buckle.

[0074] Optional, see Figure 8 and Figure 9 One end of the atomizer core 20 is sleeved on one end of the nozzle air passage 111 , and the other end is plugged into the sealing member 30 .

[0075] The device further comprises a sealing ring 60 , which is disposed at the joint between the atomizer core 20 and the nozzle air passage 111 to seal the joint gap between the two.

[0076] In this embodiment, the atomizer core 20 and the sealing member 30 are connected by interference fit, so as to achieve better sealing performance.

[0077] The key point of this embodiment lies in the connection arrangement of the atomizer core 20, the sealing member 30 and the sealing ring 60. As mentioned above, a vent hole is provided in the middle of the sealing member 30, and one end of the above-mentioned air inlet channel 310 is connected to this vent hole.

[0078] See also Figure 1 In the longitudinal direction of the atomizing device 100, the sealing member 30, the atomizing core 20, and the sealing ring 60 are connected in sequence. As can be seen from the above, the top end of the atomizing core 20 is sleeved on the bottom end of the nozzle air passage 111, and the sealing ring 60 is provided between the inner wall of the atomizing core 20 and the outer wall of the nozzle air passage 111. The sealing ring 60 can be a rubber ring. In addition, to ensure the installation and positioning of the sealing ring 60, a protrusion is provided on the outer wall of the sealing ring 60, and a slot 61 is provided at the axial end of the protrusion of the sealing ring 60. Before the atomizer core 20 is sleeved onto the nozzle airway 111, the sealing ring 60 can be first installed in the inner wall of the top end of the atomizer core 20. At this time, the top end of the atomizer core 20 is inserted into the slot 61, thereby ensuring the stability of the installation of the sealing ring 60. Then, the top end of the atomizer core 20 is sleeved onto the bottom end of the nozzle airway 111 from bottom to top. At this time, due to the limitation of the slot 61, even if the sealing ring 60 is pushed toward the inside of the atomizer core 20 by the nozzle airway 111, the sealing ring 60 will not shift.

[0079] The aforementioned seal 30 can be a silicone seat, so a socket is provided at the top of the seal 30, and the bottom end of the atomizer core 20 is inserted into the socket. Due to the relatively low hardness of the silicone seat, an interference fit can be used between the atomizer core 20 and the seal 30 to achieve a quick and reliable connection. It should be noted that, depending on design requirements, the interference fit solution between the atomizer core 20 and the seal 30 can be provided separately or combined with a solution in which the sealing ring 60 is provided at the socket connection between the atomizer core 20 and the nozzle airway 111.

[0080] See also Figure 2 and Figure 9 The atomizer core 20 includes a heating wire 21 and an atomizer cotton 22 surrounding the heating wire 21 .

[0081] The heating wire 21 is provided with two positive pins 211 and one negative pin 212 . One end of the two positive pins 211 and one negative pin 212 passes through the sealing member 30 to be connected to an external power source.

[0082] In this embodiment, the number of the positive electrode pins 211 of the heating wire 21 is two, and the number of the negative electrode pin 212 is one, thereby forming a double-fired atomizer core 20, which has a higher heating efficiency.

[0083] In this embodiment, two positive contact pieces 2111 and one negative contact piece 2121 are embedded on the bottom surface of the bottom cover 40. In addition, the positive contact piece 2111 and the negative contact piece 2121 are respectively provided with plug-in posts, which at least pass through the bottom cover 40, or after the bottom cover 40 is installed to the bottom of the shell 10, the plug-in posts are even inserted into the sealing member 30, thereby completing the fixation of each contact piece. However, it should be noted that there should be no air between the plug-in posts and the liquid absorbing part 50 to prevent the liquid in the liquid absorbing part 50 from flowing out of the shell 10 along the plug-in posts; it can be seen from the above that the double-shot structure of this embodiment shares a negative pin 212; alternatively, the double-shot structure can also share a positive pin 211.

[0084] In addition, a receiving groove 70 is provided on the bottom surface of the sealing member 30. Along the length direction, the sealing member 30 is provided with a through hole 71. The bottom end of the through hole 71 is connected to the receiving groove 70. One end of the atomizer core 20 passes through the entire through hole 71 from the top end and is received in the receiving groove 70.

[0085] Specifically, the bottom ends of the positive pin 211 and the negative pin 212 include a vertical bend to form a horizontal pin segment. Correspondingly, three horizontal receiving grooves 70 are provided on the bottom surface of the seal 30 (the side away from the liquid storage chamber 110). One end of the receiving groove 70 is provided with a through hole 71 that penetrates the seal 30. In this way, one pin corresponds to one through hole 71, passes through the through hole 71 from top to bottom, and is finally received in the receiving groove 70 at the bend. The bottom end of the pin is located in the end of the receiving groove 70 away from the through hole. The aforementioned plug-in column can be plugged into the end of the receiving groove 70 away from the through hole 71 and connected to the bottom end of the corresponding pin.

[0086] See Figure 9 In addition, the atomizer core 20 further includes a first outer protective tube 23 , in which the heating wire 21 and the atomizer cotton 22 are disposed.

[0087] In this embodiment, the atomizer core 20 further includes a second outer protective tube 24 , which is sleeved onto the first outer protective tube 23 .

[0088] Liquid holes are provided on the side walls of the first outer protective tube 23 and the second outer protective tube 24, and the liquid holes of the first outer protective tube 23 and the second outer protective tube 24, which are arranged in a mutually nested manner, are aligned so that the atomized matrix in the liquid storage chamber 110 can flow to the atomizing cotton 22 through the liquid holes. In this embodiment, the first outer protective tube 23 and / or the second outer protective tube 24 are used to connect with the nozzle airway 111 and the sealing member 30, and the first outer protective tube 23 and / or the second outer protective tube 24 mainly play a fixing role on the outside of the atomizing cotton 22. In the above scheme, according to design requirements, the first outer protective tube 23 and the second outer protective tube 24 can be provided separately or together.

[0089] The embodiment of the present application further provides an atomization device, comprising a power supply assembly and the atomization device 100 as described above, wherein the power supply assembly is electrically connected to the atomization core 20 .

[0090] The power supply assembly is used to provide electrical energy to the atomizing device 100. The power supply assembly and the atomizing device 100 can be fixedly connected or detachably connected. When the atomizing device 100 and the power supply assembly are detachably connected, the atomizing device 100 and the power supply assembly can be replaced depending on the usage.

[0091] The power supply assembly includes a power supply. Usually, the power supply is installed in the outer shell. The power supply is provided with two positive terminals and one negative terminal. Thus, when the outer shell is connected to the bottom end of the shell 10, a positive terminal is connected to a positive contact piece 2111, and a negative terminal is connected to a negative contact piece 2121.

[0092] The above description is only an implementation method of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
