Fig. 1 is a schematic view of an electronic atomization device according to an embodiment of the present application.

As shown in fig. 1, the electronic atomizing device 100 includes an atomizer 10 and a power supply assembly 20, and the atomizer 10 is not detachable from the power supply assembly 20.

The atomizer 10 is used to atomize a liquid substrate to produce an aerosol.

The battery 21 provides electrical power for operating the electronic atomizing device 100. The battery 21 may be a rechargeable battery or a disposable battery.

The circuit 22 may control the overall operation of the electronic atomizing device 100. The circuit 22 controls not only the operation of the battery cell 21 and the ultrasonic atomizing sheet 103, but also the operation of other elements in the electronic atomizing device 100.

Fig. 2 is a schematic view of another electronic atomizing device provided in an embodiment of the present application, unlike the example of fig. 1, the atomizer 10 is removably connected, such as by an interference fit, snap fit, or magnetic attraction, to the power supply assembly 20.

Fig. 3 to 9 show schematic structural views of an atomizer of an embodiment; in the atomizer of this embodiment, it includes:

a main body 101a having a suction nozzle port 101a1 for suction at a proximal end thereof; the main body 101a has a smoke output tube 1011a inside and a reservoir a with an opening at the distal end of the main body 101 a.

A bottom cover 106a detachably coupled to the opening or the opening of the distal end of the main body 101a, thereby defining a housing of the atomizer with the main body 101 a; the bottom cover 106a is provided with an air inlet 106a1.

The liquid guiding member 104a, as shown in fig. 7 to 8, integrally has a first side wall 104a1 and a second side wall 104a2 opposed in the thickness direction, and a notch 104a3 located between the first side wall 104a1 and the second side wall 104a 2; the liquid guiding element 104a further has an atomizing face 104a7 facing away from the first side wall 104a1 and/or the second side wall 104a2 and/or the recess 104a3 and/or the liquid reservoir a in the longitudinal direction. In this preferred implementation, the liquid guiding element 104a is a rigid porous body, such as a porous ceramic body.

A base portion 104a4 located at a lower end side of the liquid guiding member 104a in the longitudinal direction and extending between the first side wall 104a1 and the second side wall 104a 2; while the extension length of the base portion 104a4 along the length direction of the liquid guiding element 104a is the same as the extension length of the first side wall 104a1 and/or the second side wall 104a 2; according to the illustration, the lower surface of the base portion 104a4 is used as the atomizing face 104a7.

A connection portion 104a5 located at an upper end side of the liquid guiding member 104a in the longitudinal direction and disposed near a central portion of the liquid guiding member 104 a; also the connecting portion 104a5 extends between the first side wall 104a1 and the second side wall 104a 2; the extension length of the connecting portion 104a5 along the length direction of the liquid guiding element 104a is smaller than the extension length of the first side wall 104a1 and/or the second side wall 104a2 and/or the base portion 104a 4; further, the notch 104a3 is formed by an area not covered by the connection portion 104a 5.

Meanwhile, a space 104a6 extending in the longitudinal direction is defined between the connection portion 104a5 and the base portion 104a 4; the space 104a6 may be used to receive or buffer the liquid substrate, thereby adjusting the amount or efficiency of the liquid substrate supplied onto the atomizing face 104a7.

The connecting portion 104a5 of the liquid guiding element 104a is at least partially opposite the flue gas outlet tube 1011a in the longitudinal direction of the body 101a after assembly, whereby in practice the surface of the connecting portion 104a5 may be configured to receive aerosol condensate falling from within the flue gas outlet tube 1011a.

The heating element 103a is disposed on the atomizing surface 104a7 of the liquid guiding element 104a to form an atomizing assembly together, so as to heat at least part of the liquid matrix in the atomized liquid guiding element 104a to generate aerosol, and release the aerosol from the atomizing surface 104a7.

As a suitable choice of material, the elastomeric seal 102a is preferably a flexible material, for example, in some examples the elastomeric seal 102a may be made of a silicone, thermoplastic Elastomer (Thermo-Plastic-Elastomer), or thermoplastic Rubber (Thermo-Plastic-Rubber) material.

The elastomeric seal 102a includes an upstream end 102a1 (the end distal from the reservoir A), a downstream end 102a2 (the end proximal to the reservoir A), a body 102a3 extending from the upstream end 102a1 to the downstream end 102a 2; a sleeve portion (not shown) located between the upstream end 102a1 and the receiving cavity 102a4 is at least partially sandwiched between the inner wall of the body 101a and the outer side wall of the bottom cover 106a, and the downstream end 102a2 is held in contact with the inner wall of the body 106a to form a seal and define at least a portion of the reservoir chamber a.

In a preferred embodiment, a first bead (not shown) is disposed on the outer side wall of the body 102a3 adjacent to the upstream end 102a1, and a second bead (not shown) is disposed on the outer side wall of the body 102a3 adjacent to the downstream end 102a2, whereby a good seal is achieved.

The body 102a3 is provided with a housing chamber 102a4 and a liquid passage 102a5. The downstream end 102a2 has an opening to which the receiving chamber 102a4 is exposed, i.e., the receiving chamber 102a4 communicates with the opening. The atomizing assembly can be assembled or received within the receiving chamber 102a4 through the opening in the downstream end 102a2, and the liquid passage 102a5 communicates between the receiving chamber 102a4 and the liquid storage chamber a such that the liquid matrix can be transferred to the liquid guiding member 104a through the liquid passage 102a5.

In a preferred embodiment, another liquid guiding element (not shown) may be disposed in the liquid channel 102a5, for example: the liquid-conducting strands, which prevent the liquid matrix from flowing or being transferred directly to the liquid-conducting element 104a relatively quickly, act to regulate the rate at which the liquid matrix is transferred to the liquid-conducting element 104a. In a further preferred embodiment, a further fluid conducting element (not shown) may be provided on the elastic seal 102a, for example: a stiff organic cotton having the function of substantially sealing the opening of the reservoir a, for preventing liquid matrix from flowing out of the opening directly, so that the liquid matrix in the reservoir a can substantially only slowly permeate out through the liquid guiding element and is transferred to the liquid guiding element 104a through the liquid channel 102a5.

A portion of the outer surface of the liquid guide 104a is held in contact with the inner wall (or inner wall surface) of the receiving chamber 102a4 to block the flow of liquid matrix through the liquid channel 102a5 toward the bottom cap 106a, thereby providing a seal between the liquid storage chamber a and the air flow channel.

In a preferred embodiment, the widthwise dimension of the liquid guiding element 104a is greater than the widthwise dimension of the receiving cavity 102a4, and/or the widthwise dimension of the liquid guiding element 104a is greater than the widthwise dimension of the receiving cavity 102a 4; in this way, the fluid transfer element 104a is in an interference fit with the receiving cavity 102a4 to facilitate retention within the receiving cavity 102a4.

In a further preferred embodiment, a third rib (not shown) is formed in the body 102a3 or disposed on the outer sidewall defining the accommodating cavity 102a4, and the third rib is located between the first rib and the second rib, where the third rib can enable the elastic sealing element 102a to form a good sealing effect with the inner wall of the main body 101a on one hand, and can avoid that the elastic sealing element 102a forms a good sealing effect with the liquid guiding element 104a when the tolerance of the elastic sealing element 102a is too large on the other hand.

An aerosol passage 102a6 is also provided within the body 102a 3. The downstream end of the aerosol passage 102a6 is connected with the flue gas outlet pipe 1011a, specifically, the flue gas outlet pipe 1011a is inserted into the aerosol passage 102a6, a step is provided in the aerosol passage 102a6 to abut against the end of the flue gas outlet pipe 1011a, and the inner wall of the aerosol passage 102a6 is kept in contact with the side wall of the flue gas outlet pipe 1011a to form a seal. In the example of fig. 3-10, the upstream end of the aerosol passage 102a6 is an open end (i.e., in communication with the receiving cavity 102a 4) and abuts the connecting portion 104a 5; of course, the upstream end of the aerosol passage 102a6 may be a closed end and abut against the connecting portion 104a 5.

In other examples, as shown in fig. 10, the liquid guiding element may be a plate-shaped porous body 104b, the plate-shaped porous body 104b having a first face facing the liquid storage chamber a and a second face facing away from the liquid storage chamber a, the heating element 103a being provided on the second face; the upstream end of the aerosol passage 102a6 is closed end (i.e. spaced from the receiving cavity 102a 4) and spaced from the first face. A gap is provided between the closed end and the first face of the porous body 104b, and in some implementations, a laterally extending groove (not shown) is provided on a surface of the closed end opposite the first face of the porous body 104b, the groove constituting the gap. In this way, the liquid matrix can be transferred to the middle part of the porous body 104b through the gap between the closed end and the porous body 104b (indicated by the arrow in fig. 10), and the problem of dry combustion caused by insufficient liquid supply can be avoided.

In another example, the atomizing face of the liquid guiding element, i.e. the surface incorporating the heating element, is facing towards the liquid reservoir a, and the liquid absorbing face is facing away from the liquid reservoir a, such that the atomizing face is closer to the aerosol passage than the liquid absorbing face. In this case, the upstream end of the aerosol passage may be an open end and in fluid communication with the atomizing face of the liquid guiding element.

In the example of fig. 3 to 10, gaps remain between the first side wall 104a1 of the liquid guiding element 104a and the inner wall of the elastic seal member 102a, and between the second side wall 104a2 of the liquid guiding element 104a and the inner wall of the elastic seal member 102a in the thickness direction, thereby forming an air flow passage (i.e., a portion of the outer surface of the liquid guiding element 104a and the inner wall surface of the elastic seal member 102a remain spaced apart to form an air flow passage). During the suction process, after the air enters the atomizing chamber defined by the atomizing face 104a7, the aerosol is carried by the air flow channel across the liquid guiding element 104a or the accommodating cavity 102a4 (i.e. the aerosol flows through the side surface between the upper surface and the lower surface of the liquid guiding element 104 a), and then is output to the central portion near the smoke output pipe 1011a into the aerosol channel 102a6 and further output to the smoke output pipe 1011a. In a preferred embodiment, the inner wall (or inner wall surface) of the resilient seal 102a has a groove 102a7 to define the air flow channel with the first side wall 104a1 or the second side wall 104a 2; one end of the groove 102a7 is provided near the upstream end 102a1 of the elastic seal member 102a, and the other end extends in the longitudinal direction of the main body 101a and spans the liquid guiding element 104a or the housing chamber 102a4. As can be seen, the inner wall of the resilient seal 102a has 2 correspondingly arranged grooves 102a7; thus, each groove 102a7 forms an air flow passage with the side surface of the liquid guiding member 104a.

With further reference to fig. 9, an air flow groove 102a8 is provided in the elastic seal member 102a, and the air flow groove 102a8 is arranged along the housing chamber 102a4 and the liquid passage 102a5 to form an air pressure balance passage. Air entering the atomization cavity can flow into the liquid storage cavity A through the airflow groove 102a8, so that negative pressure in the liquid storage cavity A is relieved.

One end of the first electrode 107a is kept in contact with the electrical connection portion of the heating element 103a to form an electrical connection, and the other end of the first electrode 107a is exposed on the bottom cover 106 a; one end of the second electrode 108a is held in contact with another electrical connection of the heating element 103a to form an electrical connection, and the other end of the second electrode 108a is exposed on the bottom cover 106 a. The first electrode 107a and the second electrode 108a also serve to support the atomizing assembly to retain the atomizing assembly within the receiving cavity.

Fig. 11 to 17 show schematic structural views of a nebulizer 10 of another embodiment; in the atomizer 10 of this embodiment, it includes:

the main body 101 is substantially flat and cylindrical. The body 101 has longitudinally opposed proximal and distal ends; the proximal end is configured to serve as one end for sucking aerosol by a user, and a suction nozzle opening for sucking by the user is arranged at the proximal end; while the distal end is taken as the end to which the power supply assembly 20 is coupled and the distal end of the body 101 is open, with a removable bottom cap 106, such as a snap-fit connection, mounted thereon. After being combined with the bottom cap 106, the body 101 and the bottom cap 106 together define the housing of the atomizer 10, and the interior thereof is hollow and provided with necessary functional means for storing and atomizing the liquid matrix; through the opening of the main body 101, each necessary functional part can be installed inside the housing of the atomizer 10.

As will be understood in conjunction with fig. 17, the bottom cover 106 is provided with first electrode holes 1061 and second electrode holes 1062, to which the first electrodes 107 and the second electrodes 108 are mounted in one-to-one correspondence. The first electrode 107 and the second electrode 108 preferably employ elastic electrodes, and the atomizer 10 may be electrically connected to the power supply assembly 20 through the first electrode 107 and the second electrode 108. At the same time, an air inlet 1063 is provided in the bottom cover 106 for the entry of outside air into the atomizer 10 during suction. The bottom cover 106 is further provided with a collecting cavity 1064, and the first electrode hole 1061, the second electrode hole 1062, and the air inlet 1063 are all protruded from the collecting cavity 1064, where the collecting cavity 1064 is used for collecting the leaked liquid matrix, so as to prevent the leaked liquid matrix from flowing to the power component 20. The side wall of the bottom cover 106 has a step 1065, which is described below.

The interior of the housing is provided with a liquid storage chamber a for storing a liquid matrix, an elastic seal 102, an ultrasonic atomizing sheet 103 for ultrasonic atomizing the liquid matrix, a liquid guiding member 104 for sucking the liquid matrix, and a liquid guiding member 105 for sucking the liquid matrix from the liquid storage chamber a and transmitting the liquid matrix to the liquid guiding member 104.

A flue gas transmission pipe 1011 is arranged in the main body 101 along the axial direction, and a liquid storage cavity A for storing liquid matrixes is defined by the space among the outer wall of the flue gas transmission pipe 1011, the inner wall of the main body 101 and the first end part of the elastic sealing piece 102; one end of the fume transmission pipe 1011 is communicated with the suction nozzle, so that generated aerosol is transmitted to the suction nozzle for sucking. In a preferred embodiment, the smoke delivery tube 1011 and the main body 101 are integrally molded from a moldable material, such that the liquid storage chamber A formed after the preparation is open or open toward the distal end.

As will be appreciated in connection with fig. 14-15, the elastomeric seal 102 has a first end 1021 and a second end 1022 opposite in the longitudinal direction of the body 101. The elastomeric seal 102 is preferably made of a flexible material such as silicone, thermoplastic elastomer.

Adjacent the second end 1022, a receiving chamber 1023 for receiving the ultrasonic atomizing sheet 103 is also provided in the elastic seal 102. The liquid guide member 104 is bonded to a part of the upper surface of the ultrasonic atomizing sheet 103 and housed in the housing chamber 1023 together with the ultrasonic atomizing sheet 103; in an alternative implementation, a portion of the liquid guiding element 104 is bonded to a portion of the upper surface of the ultrasonic atomizing plate 103, and another portion of the liquid guiding element 104 is sandwiched between another portion of the upper surface of the ultrasonic atomizing plate 103 and the abutment 1024. An abutting part 1024 is arranged in the accommodating cavity 1023, and the upper surface 1031 of the part of the ultrasonic atomization sheet 103 which is not combined with the liquid guide element 104 is kept in contact with the abutting part 1024 and elastically abutted; the inner wall of the housing chamber 1023 is kept in contact with the side wall (extending from the upper surface to the lower surface) of the ultrasonic atomizing sheet 103; in this way, a good sealing effect is facilitated between the elastic sealing member 102 and the ultrasonic atomizing sheet 103. The area of the portion of the upper surface 1031 not bonded to the liquid guiding member 104 is much smaller than the area of the portion of the upper surface bonded to the liquid guiding member 104, and the portion of the upper surface 1031 not bonded to the liquid guiding member 104 is disposed next to the side wall of the ultrasonic atomizing plate 103. Because the abutting part 1024 is elastically abutted with the ultrasonic atomizing sheet 103, the ultrasonic atomizing sheet 103 can buffer vibration through the elasticity of the ultrasonic atomizing sheet 103 when vibrating at high frequency, so that damage to the ultrasonic atomizing sheet 103 is avoided.

A pair of liquid channels 1025 are symmetrically arranged along the transverse direction of the main body 101, the liquid channels 1025 penetrate from the first end to the accommodating cavity 1023, the liquid matrix in the liquid storage cavity a is transferred to the liquid guiding element 104 through the liquid channels 1025, and is atomized into aerosol under the high-frequency vibration generated by the ultrasonic atomization sheet 103, and the transfer path of the liquid matrix can be shown by referring to R1 in fig. 12. As shown in fig. 15, the port at the lower end (liquid outlet end) of the liquid channel 1025 is arranged in a step with the abutting portion 1024; the portion of the upper surface 1031 not associated with the liquid directing member 104 is offset or offset from the port at the lower end of the liquid passage 1025; the liquid guide 104 covers the port at the lower end of the liquid channel 1025.

In an alternative embodiment, liquid guide member 105 is disposed within liquid channel 1025 for drawing liquid matrix from liquid reservoir A and delivering liquid matrix to liquid guide member 104; advantageously, by liquid-guiding element 104 drawing liquid matrix from liquid-guiding element 105, excessive or too rapid transfer of liquid matrix to ultrasonic atomizing sheet 103 causing frying oil may be avoided. In alternative embodiments, the liquid guiding element 105 and the liquid guiding element 104 may be integrally formed.

In another alternative embodiment, the liquid guiding element 105 may be arranged between the elastic seal 102 and the liquid storage chamber a; in this way, the liquid matrix is drawn from the liquid storage chamber A by the liquid guiding element 105 and transferred to the liquid guiding element 104 through the liquid channel 1025.

Also included between the pair of liquid passages 1025 is an aerosol passage 1026 formed hollow therethrough, i.e., extending from the first end to the receiving cavity 1023. The other end of the flue gas transmission pipe 1011 is inserted into the aerosol channel 1026; one end of the aerosol passage 1026 is kept in contact with the liquid guiding element 104 so that the liquid guiding element 104 abuts on a part of the upper surface of the ultrasonic atomizing sheet 103; the inner wall of the aerosol passage 1026 and the upper surface of the ultrasonic atomizing sheet 103 define at least a partial atomizing chamber; the airflow guide 1027 is symmetrically provided in the thickness direction of the main body 101, and one end of the aerosol passage 1026 is recessed to form an airflow groove (not shown) communicating with the airflow guide 1027. In this way, at the time of suction (refer to R2 in fig. 13), after the outside air enters the atomizer 10 through the air inlet 1063, the outside air flows into the aerosol passage 1026 along the air flow guide 1027 and the air flow groove in a direction changing manner, flows into the smoke transmission pipe 1011 together with the aerosol formed by ultrasonic atomization, and is sucked by the user. Further, the air flow guide 1027 is also provided with an air flow guide surface (not shown) inclined with respect to the upper surface of the horizontally arranged liquid guide element 104 or the ultrasonic atomizing sheet 103 so that the redirected air flow can flow into the aerosol passage 1026 at a preset angle.

The side wall of the elastic seal 102 abuts against the inner wall of the main body 101, thereby forming a seal. Further, the side wall of the elastic seal 102 is provided with a protrusion 1028 and a protrusion 1029, the protrusion 1028 being provided near the first end and the protrusion 1029 being provided near the second end; in this way, a better seal can be created by the protrusions 1028 and 1029.

There is also a step 1020 between the receiving cavity 1023 and the second end 1022.

After assembly, the second end 1022 abuts the step 1065 of the bottom cover 106 and is clamped between the side wall of the bottom cover 106 and the inner wall of the main body 101, the step 1020 abuts the upper end face of the bottom cover 106; in this way, a good seal is facilitated between the resilient seal 102 and the bottom cover 106.

As will be understood from fig. 16, the ultrasonic atomizing plate 103 has a substantially elongated shape, unlike a conventional circular ultrasonic atomizing plate, and has a portion of its upper surface combined with the liquid guiding element 104, and a lower surface formed with a first electrical connection portion 1031 and a second electrical connection portion 1032, the first electrical connection portion 1031 being disposed next to the right end of the ultrasonic atomizing plate 103, and the second electrical connection portion 1032 being disposed next to the left end of the ultrasonic atomizing plate 103. After assembly, one end of the first electrode 107 is exposed on the bottom cover 106, and the other end is kept in contact with the first electrical connection portion 1031 to form an electrical connection; one end of the second electrode 108 is exposed on the bottom cover 106, and the other end is kept in contact with the second electrical connection portion 1032 to form an electrical connection; one end of the electrode exposed on the bottom cover 106 is electrically connected to an electrical contact (not shown) on the power supply assembly 20. The first electrode 107 and the second electrode 108 simultaneously form a support for the lower surface of the ultrasonic atomizing sheet 103 to hold the ultrasonic atomizing sheet 103 in the housing chamber 1023. In a preferred implementation, the projections of the first electrical connection 1031 and the second electrical connection 1032 on the upper surface of the ultrasonic atomizing sheet 103 at least partially overlap with the portion of the upper surface 1031 not bonded to the liquid guiding element 104; this facilitates holding the ultrasonic atomizing sheet 103 in the housing chamber 1023 by abutment of the abutment 1024 and support of the electrode.

It should be noted that, in other examples, the first electrical connection portion 1031 and the second electrical connection portion 1032 are provided on different surfaces, as well. For example: the first electrical connection portion 1031 is provided on the lower surface of the ultrasonic atomizing sheet 103, and the second electrical connection portion 1032 is provided on the upper surface of the ultrasonic atomizing sheet 103; in further implementations, the second electrical connection 1032 may also extend along the sidewall to the lower surface to be disposed on the same surface as the first electrical connection 1031.

In other examples, it is also possible to support the ultrasonic atomizing sheet 103 by any one of the first electrode 107 and the second electrode 108.

The liquid guiding element 104 is made of flexible strips or rod-like fibrous material, such as cotton fibers, nonwoven fibers, sponges, etc.

The liquid guiding member 105 is made of an organic porous material having elasticity, and exhibits moderate flexibility and rigidity. In practice, the fluid transfer element 105 has a modulus of elasticity or stiffness that is less than the body 101 or the material defining the fluid storage chamber a, and greater than the material of the fluid transfer element 104. In particular to hard artificial cotton with the Shore hardness of 20-70A. In alternative implementations, the liquid guiding element 105 is a hard rayon comprising oriented polyester fibers, or a hard rayon or rayon made of a filiform polyurethane, or the like.

FIG. 18 shows a schematic structural view of another embodiment of the elastomeric seal 102 a; unlike the elastic seal 102a illustrated in fig. 9, the following is: the air pressure equalization passage includes an air flow slot 102a81 disposed on an inner wall of the receiving chamber 102a4, and a through bore 102a82, the through bore 102a82 extending longitudinally from the downstream end 102a2 to the receiving chamber 102a4 and being physically separated from the liquid passage 102a5. Thus, the air entering the atomization cavity can flow into the liquid storage cavity A through the airflow groove 102a81 and the through hole 102a82, and the negative pressure in the liquid storage cavity A is relieved. After the liquid guide element 104a is assembled on the elastic sealing member 102a, a part of the outer surface of the liquid guide element 104a is kept in contact with the inner wall (or the inner wall surface) of the accommodating cavity 102a4, so that the air pressure balance channel is completely and physically separated from the liquid channel 102a5, and bubbles formed by entering outside air from the air pressure balance channel can directly escape into the liquid storage cavity, and the problem that bubbles are accumulated in the liquid channel 102a5 to cause unsmooth liquid draining of the liquid matrix through the liquid channel 102a5 can be avoided.

It should be noted that the air pressure balancing channel is not limited to the two cases of fig. 9 and 18. In other examples, the air pressure equalization channel may also extend from the downstream end 102a2 to the recess 102a7 or the aerosol channel 102a6, either slotted or through-hole disposed; the air pressure equalization passage may also be partially disposed between the elastomeric seal 102a and the body 101 a.
