DETAILED DESCRIPTION

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0029] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0030] It should be understood that the orientation or position relationship indicated by terms such as "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0031] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0032] As mentioned in the background art, when assembling the atomizer, the liquid matrix needs to be injected into the liquid storage cavity through the liquid injection port. In order to reduce the leakage of liquid injection, an inverted liquid injection is generally selected, that is, the liquid injection port is formed at the end of the liquid storage cavity away from the suction nozzle. However, the liquid storage cavity of the current inverted liquid injection atomizer is generally narrower near the suction nozzle. When the liquid is inverted, it is difficult for the bubbles in the liquid storage cavity near the suction nozzle to escape in time, which is prone to liquid injection leakage.

[0033] In order to solve the above problems, the embodiment of the present application provides an atomizer and an electronic atomization device, which not only sets the liquid injection port at the end of the liquid storage chamber 1000 away from the suction nozzle assembly 300 to achieve the advantages of inverted liquid injection, but also sets the suction nozzle assembly 300 and the main shell 200 separately, so that the structure of the main shell 200 is simple, and the main shell 200 can be made of materials other than plastic. For example, the main shell 200 can be made of glass, and the material compatibility of the main shell 200 is higher. In addition, the end of the main shell 200 connected to the suction nozzle 310 does not need to be radially retracted to form the suction nozzle 310, so that the inner diameter of the main shell 200 can be guaranteed to remain unchanged, and then when the atomizer is inverted, the cross-sectional size of the end of the liquid storage chamber 1000 away from the suction nozzle 310 is larger, which is conducive to the escape of bubbles during liquid injection, thereby alleviating the problem of liquid injection leakage.

[0034] The electronic atomization device provided in an embodiment of the present application is now described. The electronic atomization device includes an atomizer and a power supply assembly. The power supply assembly is used to power the atomizer. A liquid matrix is ​​stored in the atomizer. The atomizer is used to heat the liquid matrix and atomize it to form an aerosol after power is supplied.

[0035] The liquid matrix includes, but is not limited to, materials for medical, health, wellness, and beauty purposes. The power supply assembly generally includes a battery for powering the atomizer and a control circuit for controlling the heating of the atomizer. The power supply assembly may be mechanically connected to the atomizer to support the atomizer, or the power supply assembly may not be mechanically connected to the atomizer, and the two may be independently arranged.

[0036] See also Figures 1 to 3, the atomizer provided by the embodiment of the present application is now described. The atomizer includes a vent pipe 100, a main shell 200, a nozzle assembly 300 and a bottom cover 400; the main shell 200 is arranged outside the vent pipe 100 and is spaced from the vent pipe 100 to form a liquid storage chamber 1000; a flange 210 extends inward at one end of the main shell 200, the nozzle assembly 300 includes a nozzle 310 and a first sealing member 320, the first sealing member 320 abuts against the inner side of the flange 210, the nozzle 310 penetrates the flange 210 to be connected with the first sealing member 320, and at least part of the nozzle 310 abuts against the outer side of the flange 210, the nozzle 310 is sleeved outside the vent pipe 100 and communicated with the vent pipe 100; a bottom cover 400 that can be disassembled and used to seal the liquid storage chamber 1000 is provided at one end of the liquid storage chamber 1000 away from the nozzle 310.

[0037] Among them, the liquid injection port is formed at one end of the liquid storage chamber 1000 away from the suction nozzle 310. When liquid injection is required, the atomizer is turned upside down and the liquid matrix is ​​injected into the liquid storage chamber 1000 through the liquid injection port. After the liquid injection is completed, the liquid injection port is sealed through the bottom cover 400, and then the atomizer is rotated to the forward direction.

[0038] The atomizer in the embodiment of the present application is provided with a detachable bottom cover 400 at the end of the liquid storage chamber 1000 away from the suction nozzle 310, so that the atomizer can be inverted for liquid injection, thereby reducing the risk of oil leakage. At the same time, by separating the main shell 200 and the suction nozzle 310, the main shell 200 does not need to form the suction nozzle 310 by radial contraction, so that the cross-sectional area of ​​the end of the liquid storage chamber 1000 corresponding to the suction nozzle 310 will not be reduced relative to other positions of the liquid storage chamber 1000 along the axial direction, thereby reducing the problem of gas difficulty escaping at the end of the liquid storage chamber 1000 corresponding to the suction nozzle 310 during liquid injection, thereby reducing the problem of liquid injection leakage. In addition, by respectively contacting the interconnected suction nozzle 310 and the first sealing member 320 to the inner and outer sides of the flange 210, the sealing of the end of the liquid storage chamber 1000 corresponding to the suction nozzle 310 can be improved, thereby reducing the leakage of the atomizer.

[0039] It should be noted that the cross-sectional area here refers to the area of ​​the cross section perpendicular to the axial direction of the ventilation pipe 100 .

[0040] In one embodiment, the main housing 200 is made of glass. Glass has good transparency, so that the user can directly observe the internal situation of the atomizer, which is very beneficial for maintaining and checking the operating status of the atomizer; at the same time, glass has the advantages of environmental protection, good chemical stability, heat preservation, beauty, durability and high safety. It can be understood that in other embodiments of the present application, the main housing 200 can also be made of plastic or other materials.

[0041] In one embodiment, see Figure 3 The inner diameter of the main shell 200 remains unchanged from one end connected to the suction nozzle 310 to the other end, that is, the main shell 200 is roughly cylindrical, so that the cross-sectional area of ​​the end of the liquid storage chamber 1000 corresponding to the suction nozzle 310 will not become smaller due to the radial inward contraction of the main shell 200, thereby alleviating the situation in which the inverted liquid injection gas is difficult to escape.

[0042] In one embodiment, see Figure 3 , along the axial direction of the vent pipe 100, the outer diameter of the vent pipe 100 gradually decreases at least from the position close to the flange 210 to the direction of the flange 210. In this way, the cross-sectional area of ​​the liquid storage chamber 1000 can be gradually increased at least from the position close to the flange 210 to the direction of the flange 210, which can facilitate the gas at the flange 210 to quickly escape outward around the outer peripheral wall of the vent pipe 100 during liquid injection, thereby reducing oil leakage.

[0043] In one embodiment, see Figures 2 to 5 The nozzle 310 includes a nozzle appearance part 311 and a nozzle inner fastener 312. The nozzle inner fastener 312 penetrates the flange 210 to be connected with the first sealing part 320. The nozzle appearance part 311 is sleeved outside the nozzle inner fastener 312 and is clamped with the nozzle inner fastener 312. The nozzle appearance part 311 abuts against the outer side of the flange 210. In this way, the nozzle appearance part 311 and the first sealing part 320 can be respectively abutted against the inner and outer sides of the flange 210 through the clamping between the nozzle appearance part 311 and the nozzle inner fastener 312, thereby ensuring the sealing of the liquid storage chamber 1000 corresponding to one end of the nozzle 310, and further ensuring the sealing of the entire atomizer.

[0044] During assembly, the nozzle inner fastener 312 can be connected to the first sealing member 320 and sleeved on the outside of the vent pipe 100, and then the main housing 200 can be axially slid with the inner side of the flange 210 facing the first sealing member 320 until the flange 210 and the first sealing member 320 abut, and finally the nozzle appearance member 311 can be snap-fitted and sleeved on the nozzle inner fastener 312 and the outside of the vent pipe 100. It can be understood that in other embodiments of the present application, the nozzle appearance member 311 and the nozzle inner fastener 312 can also be an integral structural member, which is not limited here.

[0045] In one embodiment, see Figure 3 The nozzle appearance part 311 is connected to the ventilation pipe 100 , and the aerosol generated in the ventilation pipe 100 is discharged through the nozzle appearance part 311 .

[0046] In one embodiment, see Figure 3 , Figure 4 , Figure 6 and Figure 7The first sealing member 320 is interference fitly mounted on the outside of the ventilation pipe 100, and the inner peripheral wall of the first sealing member 320 is concavely formed with an annular groove 321, and a convex ring 3121 is convexly provided on the outer periphery of one end of the inner fastener 312 of the suction nozzle, and the convex ring 3121 is inserted into the annular groove 321; a plurality of openings 3122 are formed on the side wall of the inner fastener 312 of the suction nozzle, and the openings 3122 penetrate through one end of the inner fastener 312 of the suction nozzle where the convex ring 3121 is formed.

[0047] Specifically, the first sealing member 320 has a central hole 322 , the ventilation pipe 100 is disposed through the central hole 322 , and the first sealing member 320 is interference-fitted on the outside of the ventilation pipe 100 through the central hole 322 .

[0048] Specifically, the protruding ring 3121 is inserted into the annular groove 321 along the radial direction of the first sealing member 320 .

[0049] In this embodiment, the provision of the opening 3122 can improve the elasticity of the position of the convex ring 3121 corresponding to the inner fastener 312 of the nozzle, so that during assembly, the position of the inner fastener 312 of the nozzle corresponding to the convex ring 3121 can be squeezed radially inward to reduce the outer diameter of the position of the inner fastener 312 of the nozzle corresponding to the convex ring 3121, so that the convex ring 3121 can be inserted into the center hole 322 along the axial direction and snapped into the annular groove 321 along the radial direction. At the same time, due to the elasticity of the inner fastener 312 of the nozzle, the convex ring 3121 and the annular groove 321 are interference-fitted and firmly connected. In addition, due to the insertion of the convex ring 3121 and the annular groove 321, when the nozzle appearance 311 and the inner fastener 312 of the nozzle are snapped, the first sealing member 320 can be pressed against the inner side of the flange 210 through the convex ring 3121 to ensure the sealing of the connection between the nozzle assembly 300 and the main shell 200.

[0050] In one embodiment, see Figure 4 The inner wall of the first seal 320 is provided with a convex rib 323, which extends along the circumference of the first seal 320. The convex rib 323 is used to interfere with the outer wall of the ventilation pipe 100 to form an interference fit between the first seal 320 and the ventilation pipe 100.

[0051] In one embodiment, see Figure 4 , Figure 7 and Figure 8 The inner wall of the nozzle appearance part 311 is formed with a first step surface 3111 and a first block 3112, and the outer wall of the nozzle internal fastener 312 is formed with a second block 3123; along the axial direction of the ventilation pipe 100, the second block 3123 is stopped at the side of the first block 3112 facing the first step surface 3111, and the first end surface 3124 of the nozzle internal fastener 312 facing away from the first sealing component 320 abuts against the first step surface 3111.

[0052] During assembly, the nozzle appearance part 311 is sleeved on the outside of the nozzle inner fastener 312 and slid along the axial direction of the ventilation pipe 100 until the first clamping block 3112 is inserted into the second clamping block 3123 away from the first end face 3124 from the side of the second clamping block 3123 toward the first end face 3124, and the first end face 3124 is axially abutted against the first step surface 3111, thereby achieving axial position limitation of the nozzle appearance part 311 and the nozzle inner fastener 312. In addition, due to the axial clamping effect of the first clamping block 3112 and the second clamping block 3123, the convex ring 3121 has an axial pressing effect on the first sealing member 320, thereby improving the abutment sealing performance of the first sealing member 320 and the flange 210.

[0053] It should be noted here that the main shell 200, the first seal 320, the nozzle inner fastener 312 and the nozzle appearance part 311 are all mounted on the outside of the ventilation pipe 100. Generally, the ventilation pipe 100, the shell, the first seal 320, the nozzle inner fastener 312 and the nozzle appearance part 311 are all coaxially arranged. For the convenience of description, the axial direction of the ventilation pipe 100, the main shell 200, the first seal 320, the nozzle inner fastener 312 and the nozzle appearance part 311 is referred to as the axial direction in this application.

[0054] In one embodiment, see Figure 4 When the first clamping block 3112 and the second clamping block 3123 form a clamping connection, the second end surface 3113 of the nozzle appearance part 311 facing the main shell 200 just interferes with the outer side surface of the flange 210 along the axial direction, that is, the nozzle appearance part 311 and the first sealing part 320 interfere with the outer side surface and the inner side surface of the flange 210 respectively, thereby ensuring the sealing of the connection between the nozzle assembly 300 and the main shell 200 and the ventilation pipe 100, and further ensuring the sealing of the liquid storage chamber 1000 corresponding to one end of the nozzle assembly 300.

[0055] Optionally, the second clamping block 3123 may extend along the circumference of the inner fastener 312 of the nozzle, and the plurality of first clamping blocks 3112 may be clamped with the second clamping block 3123 at different positions along the circumference. It is understandable that in other embodiments, the number of the second clamping blocks 3123 may also be multiple, and the plurality of second clamping blocks 3123 may be clamped with the plurality of first clamping blocks 3112 in a one-to-one correspondence.

[0056] In one embodiment, see Figure 4 , Figure 7 and Figure 8The nozzle appearance part 311 is formed with a slot 3114, and the nozzle inner fastener 312 is formed with an insert block 3125, and the insert block 3125 is inserted into the slot 3114 along the axial direction of the vent 100. The insert block 3125 and the slot 3114 are inserted along the axial direction of the vent 100, so as to form a circumferential limit between the nozzle inner fastener 312 and the nozzle appearance part 311, so as to avoid the nozzle appearance part 311 rotating during use or carrying, thereby affecting the user experience.

[0057] Optionally, there are multiple insert blocks 3125, and each insert block 3125 is sequentially spaced along the circumference of the nozzle inner fastener 312. There are also multiple slots 3114, and each slot 3114 is sequentially spaced along the circumference of the nozzle appearance 311. During assembly, each insert block 3125 is plugged and matched with each slot 3114 in a one-to-one correspondence, thereby forming a circumferential limit between the nozzle appearance 311 and the nozzle inner fastener 312.

[0058] In one embodiment, see Figure 4 , Figure 7 and Figure 8 The nozzle exterior part 311 is formed with a second step surface 3115, the nozzle inner fastener 312 is formed with a third clamping block 3126, the vent pipe 100 is provided with a stop ring 110 protruding outward, and the vent pipe 100 has a third end face 120 away from the bottom cover 400; along the axial direction of the vent pipe 100, the second step surface 3115 abuts against the third end face 120, and the third clamping block 3126 abuts against the side of the stop ring 110 away from the third end face 120. The above arrangement can limit the vent pipe 100 in the axial direction. In addition, since the first sealing member 320 is interference-fitted on the vent pipe 100, the vent pipe 100 can be limited in the circumferential direction to prevent the vent pipe 100 from rotating during assembly or use.

[0059] In one embodiment, see Figure 3 , the vent tube 100 is formed with an air guide channel 130 that runs axially therethrough, and the outlet end of the air guide channel 130 is connected to the nozzle appearance part 311. A heating element 500 is provided at a position of the air guide channel 130 near the bottom cover 400, and the heating element 500 is electrically connected to the power supply assembly. A liquid inlet hole 140 is formed on the side wall of the vent tube 100 at a position corresponding to the heating element 500, and the liquid inlet hole 140 is connected to the liquid storage chamber 1000. The liquid matrix in the liquid storage chamber 1000 is introduced into the heating element 500 via the liquid inlet hole 140. When the power supply assembly supplies power to the heating element 500, the heating element 500 heats the atomized liquid medium to generate aerosol particles, and the airflow in the air guide channel 130 carries the aerosol particles to the nozzle appearance part 311 for the user to inhale.

[0060] In one embodiment, see Figure 5The heating element 500 includes a ceramic core 510, an oil-absorbing cotton 530 and a heating wire 540. The oil-conducting cotton 520 is sleeved on the outside of the ceramic core 510, the oil-absorbing cotton 530 abuts against the ceramic core 510 and the end surface of the oil-conducting cotton 520 away from the nozzle assembly 300, and the heating wire 540 is wound around the inner circumferential wall of the ceramic core 510. The opposite ends of the heating wire 540 are respectively led out from the ceramic core 510 for electrical connection with the power supply assembly. The liquid matrix in the liquid storage chamber 1000 enters the oil-conducting cotton 520 from the liquid storage chamber 1000 through the liquid inlet hole 140, and is adsorbed and stored by the oil-conducting cotton 520. The liquid matrix in the oil-conducting cotton 520 is guided to the porous ceramic core 510. When the power supply assembly energizes the heating wire 540, the heating wire 540 is heated to heat the liquid matrix in the ceramic core 510 to atomize and form an aerosol.

[0061] In one embodiment, see Figure 3 and Figure 5 The end of the ventilation tube 100 away from the inner fastener 312 of the suction nozzle is sleeved with an atomizer seat 600, and the atomizer seat 600 is sleeved with the ventilation tube 100 by interference fit. The atomizer seat 600 is at least sleeved on the outside of the ventilation tube 100 where the heating element 500 is provided. The atomizer seat 600 is used to form an electrical connection and a mechanical connection between the atomizer and the power supply assembly.

[0062] In one embodiment, see Figure 5 A first electrode 700 is provided in the inner cavity of the atomizer seat 600 at a position away from the heating element 500. The atomizer seat 600 is made of a conductive material and serves as a second electrode. An insulating sleeve 800 is sleeved between the first electrode 700 and the atomizer seat 600. The opposite ends of the heating wire 540 are respectively connected to the atomizer seat 600 and the first electrode 700. The atomizer seat 600 and the first electrode 700 are respectively electrically connected to the positive and negative electrodes of the power supply assembly, so that the power supply assembly can supply power to the heating element 500. Directly using the atomizer seat 600 as the second electrode can simplify the structure of the atomizer.

[0063] In one embodiment, see Figure 5 An external thread is formed on the outer periphery of one end of the atomizer seat 600 away from the heating element 500, and the atomizer seat 600 forms a detachable electrical connection with the power supply assembly through the external thread.

[0064] In one embodiment, see Figure 5 An air inlet hole 610 is formed on the side wall of the atomizer seat 600, and the air inlet hole 610 is connected to the inner cavity of the atomizer seat 600, and the inner cavity of the atomizer seat 600 is connected to the air guide channel 130 of the ventilation tube 100. The external atmosphere or the airflow delivered from the power supply assembly enters the air guide channel 130 through the air inlet hole 610, and carries the aerosol to the nozzle appearance part 311 for the user to inhale.

[0065] In one embodiment, see Figure 5 The bottom cover 400 includes a bottom plate 410 and a sleeve 420 formed on the bottom plate 410, the sleeve 420 is sleeved with the atomizer seat 600, and a second sealing member 900 is abutted between the bottom plate 410 and the main housing 200 along the axial direction of the vent pipe 100. The second sealing member 900 is provided to ensure the sealing between the bottom cover 400 and the main housing 200, and further ensure the sealing of the liquid storage chamber 1000.

[0066] In one embodiment, see Figure 5 The second sealing member 900 includes a contact portion 910 and a sleeve portion 920 formed on the contact portion 910. The contact portion 910 contacts between the bottom plate 410 and the main housing 200 along the axial direction of the vent pipe 100, and the sleeve portion 920 is sleeved between the sleeve 420 and the main housing 200. The setting of the sleeve portion 920 not only improves the connection stability between the second sealing member 900 and the bottom cover 400, but also improves the sealing performance between the bottom cover 400 and the main housing 200.

[0067] In one embodiment, see Fig. 9 The inner and outer walls of the sleeve part 920 are concave to form a plurality of grooves 930, and the grooves 930 are arranged in sequence and spaced apart along the circumference of the sleeve part 920. The arrangement of the grooves 930 can increase the structural elasticity of the sleeve part 920, and facilitate the interference fit of the sleeve part 920 between the sleeve 420 and the main shell 200.

[0068] In one embodiment, see Figure 5 , the sleeve 420 is threadedly connected to the atomizer seat 600. During assembly, it is only necessary to sleeve the second sealing member 900 on the bottom cover 400, and then sleeve the second sealing member 900 and the bottom cover 400 as a whole on the outside of the atomizer seat 600, and rotate the bottom cover 400 so that the bottom cover 400 is threadedly connected to the atomizer seat 600. Among them, the setting of the threaded connection can not only make the bottom cover 400 detachable, but also ensure that the second sealing member 900 is interference-contacted between the bottom cover 400 and the main housing 200 by rotating the bottom cover 400 during assembly to ensure the connection sealing. In addition, the sealing of the threaded connection is also good, which can ensure the connection sealing between the bottom cover 400 and the atomizer seat 600.

[0069] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
