Background

The electronic atomizing device in the related art generally comprises a nebulizer and a host for providing electric power for the nebulizer, wherein the nebulizer generally comprises a containing cavity for containing the liquid aerosol-generating substrate, and the containing cavity generally has good air tightness and liquid tightness so as to prevent the nebulizer from leaking out of the liquid aerosol-generating substrate, thereby causing bad use experience.

With the use of the electronic atomizing device by a user, the liquid aerosol generating substrate in the accommodating cavity gradually decreases, and the negative pressure in the accommodating cavity gradually increases due to the good air tightness and liquid tightness of the accommodating cavity. However, the presence of negative pressure may cause a non-smooth draining of the liquid aerosol-generating substrate, which in turn affects the atomization efficiency, and in order to keep the pressure in the receiving chamber constant, the receiving chamber of the related art is usually provided with ventilation channels.

However, when the viscosity of the liquid aerosol-generating substrate is high (for example, the dynamic viscosity exceeds 500cp at normal temperature), in the case of a pressure difference generated during the process of sucking or injecting the liquid into the atomizer by the user, the liquid aerosol-generating substrate may enter the ventilation channel in the related art, so that the ventilation channel is blocked and cannot be ventilated, thereby affecting the normal liquid discharge of the aerosol-generating substrate and the atomization efficiency.

The electronic atomizing device of some embodiments of the present utility model may be used to heat atomize a liquid aerosol-generating substrate of high viscosity (e.g., a kinetic viscosity in excess of 500cp at ambient temperature) to form an aerosol for inhalation by a user. The electronic atomizing device may in some embodiments comprise an atomizer 1 and a host computer, the atomizer 1 being detachably plugged onto the host computer in a longitudinal direction of the electronic atomizing device, and being adapted to receive a liquid aerosol-generating substrate and atomize the aerosol substrate. The host may be used to provide power to the atomizer 1 and may be used to control the operation of the entire electronic atomizing device 1. It will be appreciated that the nebuliser 1 may in some embodiments be a disposable nebuliser, which may be replaced by a new one when the liquid aerosol-generating substrate inside it is consumed; the atomizer 1 may in some embodiments also be a multiple use atomizer, which may be replenished with liquid aerosol-generating substrate after its interior has been consumed, to achieve reuse.

As shown in fig. 1 and 2, the atomizer 1 may be in the form of a flat column in some embodiments, and may have a racetrack cross section. Referring to fig. 3 and 4 together, the atomizer 1 may in some embodiments include a housing assembly 10 and an atomizing body 20 mounted inside the housing assembly 10.

Because the connecting member 12 is made of a silica gel material in some embodiments, the connecting member has a certain oleophobicity, and can facilitate the backflow of the condensed liquid aerosol-generating substrate on the inner wall surface of the connecting member 12, so as to prevent the liquid aerosol-generating substrate from being sucked out by a user, and cause bad use experience. The bottom cover 14 is in some embodiments elongated and cylindrical and snap-fitted to the bottom of the housing 13, the bottom cover 14 together with the housing 13 forming a space for receiving the atomizing body 20.

The first hook 123 can be matched with the first slot 112 on the suction nozzle 11 and is clamped together to connect the suction nozzle 11 and the connecting piece 12. The first air guide chamber 121 is smaller in diameter and can be used for ventilation of the atomizer 1 as required when aerosol-generating substrate is reduced. The first mounting hole 122 may be mounted to the housing 13 to allow communication between the housing 13 and the connector 12.

Referring again to fig. 5 to 8, the housing 13 may include a housing 130, an air duct 131 disposed in the housing 130, a first oleophilic section 133 formed on the housing 13, a liquid storage cavity 134 defined between the housing 130 and the air duct 131, second hooks 135 disposed on the inner surface of the housing 130 and on opposite sides of the long axis of the housing 13, and third hooks 136 disposed under the second hooks 135, respectively. In some embodiments, the first oleophilic segment 133 is located below the reservoir 134 and is in communication with the reservoir 134. The second hook 135 can be matched with the second slot 113 on the suction nozzle 11 and clamped together to connect the suction nozzle 11 with the housing 13.

The baffle wall 137 defines, in conjunction with the housing 130, the reservoir 134 for receiving the liquid aerosol-generating substrate and also defines a receiving cavity 138 for receiving the atomizing body 20. The blocking wall 137 is located below the liquid storage cavity 134, and the first oleophilic segment 133 is formed by penetrating from the top surface to the bottom surface of the blocking wall 137.

The air duct 131 is installed in the first installation hole 122 of the connector 12 and is in air-guide communication with the nozzle hole 111 of the nozzle portion 11 upward, and the air duct 131 can be used for guiding out the aerosol generated by the atomizing body 20. The upper end of the liquid storage cavity 134 is in air guide connection with the first air guide cavity 121 of the connecting piece 12, so that the first air guide cavity 121, the liquid storage cavity 134 and the first lipophilic segment 133 are in air guide communication in sequence; thus, the first oleophilic segment 133 can be used for ventilation of the reservoir 134 as required by pressure changes as the aerosol-generating substrate is reduced. The reservoir 134 may in some embodiments be adapted to hold a liquid aerosol-generating substrate and be in communication with the first oleophilic segment 133 to ensure that the pressure level within the reservoir 134 holding the liquid aerosol-generating substrate is in a relatively stable state.

The sealing member 21, which may be made of silicone material in some embodiments, may be disposed at an upper end of the atomizing base 22 and is in sealing connection with the housing 13 of the housing assembly 10 to seal the liquid storage cavity 134 of the housing 13. Specifically, the seal 21 is abutted against the bottom surface of the blocking wall 137 in the housing 13.

The atomizing base 22 is mounted in the housing 13 and abuts against the blocking wall 137 in the longitudinal direction of the atomizer 1 via the seal 21. The mounting base 23, which may be made of silica gel in some embodiments, is mounted between an upper base 221 and a lower base 222 of the atomizing base 22, and is used to fix the atomizing assembly 24. The atomizing assembly 24 is mounted in the mount 23 and abuts an electrode 25, which can be used to heat a liquid aerosol-generating substrate. The atomizing base 22 is hollow and defines an atomizing chamber 2226. In some embodiments, the atomizing chamber 2226 is formed by the lower base 222 in conjunction with the upper base 221, and is configured to atomize a liquid aerosol-generating substrate and to receive the aerosol generated. The mount 23 and atomizing assembly 24 are mounted in the atomizing chamber 2226. The electrodes 25 are disposed in pairs and are elongated, with their lower ends respectively mounted in the lower housing 222, and their upper ends respectively abutting against the atomizing assembly 24 to provide the atomizing assembly 24 with electric energy required for atomization.

The oleophobic section 211 is positioned corresponding to the first oleophilic section 133 and is connected in series with the first oleophilic section 113, which can extend from the top surface to the bottom surface of the seal body 210. The oleophobic section 211 can be in air-conducting communication with the first oleophilic section 133 and, along with the first oleophilic section 133, ensures that the pressure level within the liquid reservoir 134 containing the liquid aerosol-generating substrate is in a relatively stable state. The second mounting holes 212 are provided at the bottom of the seal body 210, and in some embodiments, the number of the second mounting holes 212 is 4, and the second mounting holes 212 can be used to mount the seal 21 on the lower base 22. A second air vent 213 is provided in the center of the seal body 210 and is in communication with the air vent 131 of the housing 13, which can be used to conduct out aerosol generated by the atomizing assembly 24. The first liquid guiding hole 214 is in liquid connection with the liquid storage cavity 134, and is used for guiding the liquid aerosol-generating substrate in the liquid storage cavity 134 to the atomizing assembly 24 for heating and atomizing by the atomizing assembly 24.

The upper base 221, which is mounted at the lower end of the sealing member 21 and is tightly attached to the sealing member 21 in some embodiments, may include an upper base body 2210 made of a lipophilic material, a mounting post 2211 disposed on the upper base body 2210, second liquid guiding holes 2212 disposed at two opposite ends on a long axis of the upper base body 2210, second lipophilic sections 2213 disposed at two opposite ends on a short axis of the upper base body 2210, fourth hooks 2214 disposed at two outer sides of two opposite ends on the long axis of the upper base body 2210, and a third liquid guiding hole 2215 disposed at the center of the upper base body 2210.

The upper housing body 2210 may, in some embodiments, include a top wall 2216, the top wall 2216 being formed by an upper planar surface of the upper housing body 2210. The mounting post 2211 is disposed on the top surface of the top wall 2216; the second lipophilic segment 2213 is formed by penetrating the top and bottom surfaces of the top wall 2216.

The number of the mounting posts 2211 is four in some embodiments and is disposed corresponding to the second mounting hole 212, and the mounting posts 2211 are positioned corresponding to the second mounting hole 212 and can be embedded in the mounting hole 212 to achieve tight connection between the upper housing 221 and the sealing member 21. The second liquid guiding hole 2212 corresponds to the first liquid guiding hole 214 in position, and is in liquid guiding connection, so as to guide the liquid aerosol-generating substrate accommodated in the liquid storage cavity 134 into the atomizing assembly 24, and for the atomizing assembly 24 to atomize the liquid aerosol-generating substrate.

Referring to fig. 4, the second oleophilic segment 2213 is located corresponding to the oleophobic segment 211 and is in communication with the oleophobic segment 211 and the first oleophilic segment 133, respectively, which can be used to ensure that the pressure level in the liquid storage chamber 134 containing the liquid aerosol-generating substrate is in a relatively stable state. Meanwhile, since the lipophilic segment 113 is communicated with the liquid storage cavity 134, the second lipophilic segment 2213 is also communicated with the external air guide through the lower seat 222; the first oleophilic segment 133, the oleophobic segment 211 and the second oleophilic segment 2213 constitute a ventilation channel T of the atomizer 1.

Specifically, the housing 13 in which the first lipophilic segment 133 is located may be made of a lipophilic material in some embodiments, and the first lipophilic segment 133 is a first segment of the ventilation channel T, which is in communication with the liquid storage cavity 134. The seal 21 in which the oleophobic section 211 is located may be made of an oleophobic material in some embodiments, the oleophobic section 211 being the second section of the ventilation channel T. The oleophobic section 211 is remote from the reservoir 134 relative to the first oleophilic section 133; the first oleophilic segment 133 is positioned adjacent to the reservoir 134 relative to the oleophobic segment 211. The atomizing base 22 where the second lipophilic portion 2213 is located can be made of a lipophilic material in some embodiments, which is the third portion of the ventilation channel T. One end of the second lipophilic segment 2213 is communicated with one end of the oleophobic segment 211 away from the liquid storage cavity 134, and the other end of the second lipophilic segment 2213 is communicated with the atomization cavity 2226.

In some embodiments, the oleophilic material can include a plastic material and the oleophobic material can include a silicone material. It will be appreciated that other materials or coatings than plastics materials and silica gel materials which are capable of being oleophilic or oleophobic are also suitable.

The length of the first lipophilic segment 133 should be greater than or equal to 2mm and less than or equal to 10mm, and the diameter of the first lipophilic segment 133 is within 1 mm. The first oleophilic segment 133 is longer than the length of the oleophobic segment 221 and the resulting resistance of the liquid aerosol-generating substrate along its inner wall surface of the first oleophilic segment 133 is capable of overcoming the pressure differential created during aspiration or priming.

The length of the oleophobic section 211 is above 0.2mm, and the diameter of the oleophobic section 211 is less than or equal to the diameter of the first oleophilic section 133. Since the oleophobic section 211 may be made of an oleophobic material in some embodiments, liquid aerosol-generating substrate is not present within the oleophobic section 211, thereby preventing liquid aerosol-generating substrate from entering the oleophobic section 211 and thereby preventing the ventilation channel T from entering too much liquid aerosol-generating substrate.

The second lipophilic segment 2213 is the same as the first lipophilic segment 133, and the atomizing base 22 and the baffle 137 where they are respectively located are made of lipophilic materials, and the second lipophilic segment 2213 can be used for accommodating the liquid aerosol generating substrate breaking through the oleophobic segment 211, so as to prevent the atomizer 1 from leaking. In some embodiments, the first oleophilic segment 133 and the oleophobic segment 211 can form a segment set C, it being understood that the number of segment sets C is not limited to one, two, three, or more as well. Specifically, the segment group C may be arranged in series in plural groups, to constitute the ventilation passage T.

The ventilation pathway T may in some embodiments include one or more segment groups C of first oleophilic segments 133 and oleophobic segments 211 and a second oleophilic segment 2213 disposed after the last segment group C. The second oleophilic segment 2213 is used for accommodating a liquid aerosol-generating substrate that breaks through the last oleophobic segment 211. It will be appreciated that the second oleophilic segment 2213 is not necessary and that the ventilation channel T may also be adapted to include only one or more segment sets C.

The fourth hook 2214 may be used to connect to the lower housing 222. The third air vent 2215 is disposed in the center of the upper housing body 2210 and penetrates through the upper housing body 2210 in some embodiments, and the third air vent 2215 corresponds to the second air vent 213 and the air vent 131, which can be used for guiding the aerosol generated by the atomizing assembly 24 upwards and conducting the aerosol to the outside through the nozzle hole 111.

The lower housing 222 may include a lower housing body 2220, a fourth air guide hole 2223 disposed at the center of the lower housing body 2220, fourth clamping grooves 2224 disposed at two opposite ends of the long axis of the lower housing body 2220, air exchange holes 2225 disposed at two opposite ends of the short axis of the lower housing body 2220, an atomization chamber 2226 formed by the lower housing body 2220 and the upper housing body 2210, and mounting holes 2227 disposed at the bottom of the lower housing body 2220 and symmetrically disposed at intervals on the long axis of the lower housing body 222. The mounting holes 2227 are used in some embodiments to mount a pair of electrodes 25, respectively. In some embodiments, the ventilation channel T communicates with the nebulization chamber 2226.

The lower housing body 2220 may include a bottom wall 2221 and two columns 2222 mounted to opposite ends of the long axis of the bottom wall 2221, respectively, in some embodiments. Two columns 2222 are arranged at intervals, the atomizing cavity 2226 is located between the two columns 2222, and a plurality of grooves are arranged on the two columns 2222 for guiding air. The fourth clamping groove 2224 is disposed on the two columns 2222 and located at the outer side of the lower base body 2220, and can be clamped with the fourth clamping hook 2214 on the upper base 221, so as to realize the connection between the upper base 221 and the lower base 222.

The fourth air hole 2223 is disposed at the center of the bottom wall 2221 and penetrates the bottom wall 2221, and can be in communication with the external air, and corresponds to the position of the third air hole 2215, and is in communication with the third air hole 2215, the second air hole 213 and the air pipe 131 sequentially, which can be used for air intake of the atomizer 1, specifically, for introducing the air in the environment into the atomization cavity 2226. In one aspect, during the process of sucking the suction nozzle 111 by the user, the air can be introduced from the environment through the fourth air guide hole 2223 to generate an air flow to guide out the aerosol generated by the atomizing assembly 24. On the other hand, during the process of reducing the liquid aerosol-generating substrate in the liquid storage chamber 134, the liquid storage chamber 134 may be filled with the ambient gas through the fourth gas-guiding hole 2223 to ensure the pressure inside thereof to be stable. The ventilation holes 2225 are respectively arranged at two opposite sides of the fourth ventilation hole 2223, and can be used for ventilation between the atomizer 1 and the outside. An atomizing chamber 2226 is formed between the two liquid reservoirs 2502 and is in communication with the fourth air vent 2223, and is configured to receive an aerosol generated by atomizing from the atomizing assembly 24.

The mounting base 23 is configured in a rectangular frame in some embodiments, and includes a first sidewall 231, a second sidewall 232 opposite the first sidewall 231, a third sidewall 233, and a fourth sidewall 234 opposite the third sidewall. The first, second, third and fourth side walls 231, 232, 233 and 234 are arranged in a stepped manner and have a smaller receiving space at an upper portion and a larger receiving space at a lower portion.

The atomizing assembly 24 may, in some embodiments, include a wicking unit 241 and a heat generating unit 242 mounted below the wicking unit 241. The liquid absorbing unit 241 and the heat generating unit 242 have rectangular plate shapes, and in some embodiments, the heat generating unit 242 is electrically connected to the positive and negative electrodes of the electrode 25, respectively. The cross section of the liquid sucking unit 241 perpendicular to the longitudinal direction of the atomizer 1 is smaller than the cross section of the heat generating unit 242.
