The term "and/or" as used in this specification includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1 to 9, the electronic atomizing device 100 includes a suction nozzle 11, a housing 12, a base 13, a liquid storage case 14, an upper end cap 15 (first end cap), a lower end cap 16 (second end cap), a transfer tube 17, a liquid storage member 18, a heating assembly 19, and a battery cell 20. The heating assembly 19 includes a base 191 and an atomizing core 192.

The suction nozzle 11 has a connection pipe 111 extending downward from a nozzle end.

The upper and lower ends of the housing 12 are open ends. The suction nozzle 11 is disposed at an upper open end of the housing 12, and the base 13 is disposed at a lower open end of the housing 12.

A reservoir 14, an upper end cap 15, and a lower end cap 16 are disposed within the housing 12.

The reservoir housing 14 is generally cylindrical. The upper and lower ends of the reservoir housing 14 are also open ends. The upper end cap 15 is disposed on or covers the upper end (third end) of the liquid storage case 14, and the lower end cap 16 is disposed on or covers the lower end (fourth end) of the liquid storage case 14.

The upper end cap 15 and the lower end cap 16 are made of sealing materials, such as silica gel.

Referring to fig. 5, the outer wall of the upper end cap 15 has radially extending protrusions 151 thereon.

The part of the upper end cover 15 above the bulge 151 extends into the suction nozzle 11, and the end surface of the lower end of the suction nozzle 11 is abutted with the upper surface of the bulge 151 to form a seal. The connection pipe 111 communicates with the through hole 152 of the upper cap 15.

In further implementation, the upper surface (or the surface facing away from the liquid storage cavity) of the upper end cover 15 is provided with a containing groove 153, and a liquid absorbing member A is arranged in the containing groove 153 and provided with a through hole for air flow to pass through; in this way, the liquid absorbing member A can absorb the condensed liquid matrix in the suction nozzle 11, thereby preventing the condensed liquid matrix from being sucked by a user.

The portion of the upper end cap 15 below the projection 151 extends into the reservoir 14. The outer wall of the upper end cover 15 of the part is abutted with the inner wall of the liquid storage shell 14 to form a seal; further, the outer wall of the upper end cover 15 is provided with a bump so as to form a good sealing effect with the inner wall of the liquid storage shell 14. An end surface of the upper end of the liquid storage case 14 abuts against the lower surface of the convex portion 151 to form a seal.

Similarly, the outer wall of the lower end cap 16 has a radially extending projection 161 thereon, and a portion of the lower end cap 16 above the projection 161 extends into the reservoir 14. The outer wall of the part of the lower end cover 16 is abutted with the inner wall of the liquid storage shell 14 to form a seal; further, the outer wall of the portion of the lower end cap 16 has a protrusion to form a good seal with the inner wall of the reservoir housing 14. An end surface of the lower end of the liquid storage case 14 abuts against the upper surface of the projection 161 to form a seal.

A transfer tube 17 is located in the reservoir 14. The upper end of the transfer tube 17 is held in the through hole 152 of the upper end cap 15 (i.e., connected to the upper end cap 15), and the lower end of the transfer tube 17 is accommodated in the base 191 and abuts against the end face of the upper end of the atomizing core 192 (i.e., is connected to the lower end cap 16 via the base 191). In other examples, the lower end of the transfer tube 17 may be directly connected to the lower end cap 16.

The gap between the inner wall of the reservoir housing 14, the upper end cap 15, the lower end cap 16, the base 191 and the outer wall of the transfer tube 17 defines a reservoir chamber (not shown) for storing the liquid matrix.

The reservoir 18 is disposed within the reservoir chamber. The reservoir 18 is for adsorbing and holding a liquid matrix, preferably made of cotton fiber media. The body 181 of the reservoir 18 is generally cylindrical. The reservoir 18 has a through hole 182 through which the transfer tube 17 passes. In some embodiments, a bayonet (not shown) is formed on a side wall of the liquid storage member 18, so that the liquid storage member 18 has a C-shape, and the liquid storage member 18 can be conveniently clamped around the transmission tube 17.

The upper end of the liquid storage member 18 may be held in contact with the end surface of the lower end of the upper end cap 15, or at least partially spaced apart from the end surface of the lower end of the upper end cap 15 to form the cavity B. Similarly, the lower end of the reservoir 18 may be held in contact with the end surface of the upper end of the lower end cap 16, or alternatively, the lower end of the reservoir 18 may be at least partially spaced from the end surface of the upper end of the lower end cap 16 to form another cavity (not shown). In the example of fig. 1-9, the upper end of the reservoir 18 is partially spaced from the end face of the lower end of the upper end cap 15 to form a cavity B, while the lower end of the reservoir 18 may remain in contact with the end face of the upper end of the lower end cap 16. The cavity can increase the volume of the liquid storage cavity on one hand and is beneficial to release trapped air or gas in the liquid storage piece 18 on the other hand.

If the outer wall of the liquid storage member 18 is in contact with or interference fit with the inner wall of the liquid storage shell 14, after the liquid storage member 18 adsorbs the liquid matrix, due to the air impermeability of the liquid matrix, when the liquid matrix at the lower end of the liquid storage member 18 is consumed, negative pressure is easily formed at the upper end of the liquid storage member 18, so that the transfer of the liquid matrix is not facilitated. To avoid this problem, in the example of fig. 1 to 9, on the one hand, the outer wall of the liquid storage member 18 is further provided with a groove 183, the groove 183 communicates with the upper and lower ends of the liquid storage member 18, and the groove 183 defines a first air pressure balancing channel; on the other hand, the upper end cover 15 is further provided with a through hole 154, the through hole 154 communicates the inside of the liquid storage shell 14 with the outside, and the through hole 154 defines a second air pressure balance channel for providing a path for discharging air to the outside of the liquid storage cavity or supplementing air to the inside of the liquid storage cavity; the first air pressure balance channel and the second air pressure balance channel are communicated through the cavity B in a fluid way; in some examples, it is also possible that the first air pressure balancing channel and the second air pressure balancing channel are in fluid communication through the liquid storage member 18 (the liquid storage member 18 itself has air permeability, for example, when the part of the liquid storage member 18 near the upper end cover 15, the adsorbed liquid matrix flows downwards, the first air pressure balancing channel and the second air pressure balancing channel are communicated through the part of the liquid storage member 18); in some examples, direct fluid communication between the first and second pressure equalization channels is also possible. Further, as can be seen from fig. 5, the accommodating groove 153 has a plurality of space grooves C, the space grooves C are formed by recessing a part of the bottom surface of the accommodating groove 153, and the space grooves C can collect the condensed liquid matrix in the suction nozzle 11; an opening of one end of the through-hole 154 may be provided in one of the space grooves C, and the plurality of space grooves C may be spaced apart from one another along the circumferential direction of the receiving groove 153, so that condensate may be uniformly and sufficiently collected.

Thus, when negative pressure is formed at the upper end of the liquid storage member 18, external air can enter the liquid storage shell 14 through the through hole 154, so that the air pressure inside and outside the liquid storage shell 14 is kept balanced, and the air pressure at the upper end and the lower end of the liquid storage member 18 is kept balanced through the groove 183, so that the transfer of liquid matrixes is facilitated. In addition, the groove 183 makes the outer wall of the liquid storage member 18 and the inner wall of the liquid storage shell 14 have a certain gap, and the gap can ensure that the liquid storage member 18 has a certain expansion space in high temperature environment, so as to avoid the problem of liquid leakage caused by the liquid matrix flowing out from the liquid guide hole 191a of the atomizing core 192.

In an alternative embodiment, as shown in fig. 10, a groove 183a may be formed on the inner wall of the reservoir 18. Similar to the foregoing, the air pressure at the upper and lower ends of the reservoir 18 is maintained in equilibrium by the grooves 183.

The groove (groove 183 or groove 183 a) may extend axially along the outer wall or the inner wall of the reservoir 18, or may be bent or spirally extended from the lower end of the reservoir 18 to the upper end of the reservoir 18. The groove may be formed on the outer wall or the inner wall of the liquid storage member 18, or may be formed so that a certain gap is provided between the outer wall of the liquid storage member 18 and the inner wall of the liquid storage case 14, or between the inner wall of the liquid storage member 18 and the outer wall of the transfer tube 17.

In another alternative embodiment, as shown in fig. 11, the liquid storage member 18 and the liquid storage shell 14 are both substantially cylindrical, and the liquid storage member 18 and the liquid storage shell 14 are both circular in cross section; considering the portion of the transfer tube 17, the cross-section of the reservoir 18 has a diameter d1 and the reservoir 14 has a cross-section with a diameter d2, d1< d2. Thus, in any cross-section along the length of the reservoir 18, the reservoir 18 does not fully occupy the reservoir cavity, and the cross-sectional area of the reservoir 18 is smaller than the cross-sectional area of the reservoir 14. Thus, there is a gap between the outer wall of the reservoir 18 and the inner wall of the reservoir housing 14. The air pressure at the upper end and the lower end of the liquid storage piece 18 is balanced through the gap between the outer wall of the liquid storage piece 18 and the inner wall of the liquid storage shell 14. Similarly, a similar gap may be formed between the inner wall of the reservoir 18 and the outer wall of the transfer tube 17.

In yet another alternative embodiment, as shown in fig. 12, the reservoir 18 has a through hole 183c therein extending from the lower end of the reservoir 18 to the upper end of the reservoir 18. The cross-sectional formation of the through hole 183c is not limited, for example: may be circular, oval, triangular, quadrilateral, other irregular, etc. The through hole 183c may extend axially, curved or helically within the reservoir 18. The air pressure at the upper and lower ends of the reservoir 18 is balanced by the through hole 183c.

In yet another alternative embodiment, as shown in FIG. 13, a vent tube 183d is disposed within the recess 183. The rigidity of the material of the vent tube 183d may prevent the reservoir 18 from collapsing or collapsing when inflated. Thus, the air pressure at the upper and lower ends of the reservoir 18 is balanced by the grooves 183 or the vent tubes 183d.

In the above example, the vent pipe 183d may be provided in each gap. That is, the breather pipe 183d may be provided between the outer wall of the reservoir 18 and the inner wall of the reservoir housing 14, between the inner wall of the reservoir 18 and the outer wall of the transfer pipe 17, interposed in the reservoir 18, and the like.

The embodiments of the groove, the gap, the through hole, the vent pipe, and the like may be combined.

For the through-hole 154, in an alternative embodiment, it is also possible to communicate the inside of the liquid storage case 14 with the outside through a through-hole formed in the lower end cap 16 or the transfer tube 17. In another alternative embodiment, it is also possible to communicate the inside of the liquid storage case 14 with the outside through a gap between the upper end cap 15 and the transfer tube 17, or a gap between the lower end cap 16 and the transfer tube 17 (when the lower end of the transfer tube 17 is directly connected to the lower end cap 16), or a gap between the lower end cap 16 and the base 191 (when the lower end of the transfer tube 17 is connected to the lower end cap 16 through the base 191), or a gap between the upper end cap 15 and the liquid storage case 14, or a gap between the lower end cap 16 and the liquid storage case 14. Similar to the foregoing, the above-described through holes, gaps may be used in combination.

The lower end of the seat 191 is held in the through hole 162 of the lower end cap 16. The base 191 has a housing chamber therein for housing the atomizing core 192. The side wall of the base 191 is provided with a liquid guide hole 191a communicated with the liquid storage cavity and the atomization core 192, and a sleeve (not shown) is sleeved on the base 191 and the transmission pipe 17; the cannula may draw up the liquid matrix stored within the reservoir and transfer it to the atomizing core 192 through the liquid transfer port 191 a. In other examples, the sleeve may be omitted.

The atomizing core 192 is disposed adjacent the lower end cap 16. The atomizing core 192 includes a liquid guiding element 1921 and a heating element 1922. The liquid guiding element 1921 may be, for example, cotton fiber, metal fiber, ceramic fiber, glass fiber, porous ceramic, or the like, and is preferably a tubular structure made of cotton fiber and configured to extend in the longitudinal direction of the electronic atomizing device 100. The heating element 1922 is a heating mesh made of a resistive material. The heating element 1922 may be disposed on an inner wall of the fluid guide element 1921. In other examples, the atomizing core 192 may be disposed extending along a lateral direction of the electronic atomizing device 100, such as: the heating element 1922 is wrapped around the fluid guide element 1921 and laterally across the base 191; wherein the heating element 1922 is disposed within the base 191, both ends of the fluid guide element 1921 may extend into the fluid reservoir.

The aerosol generated by heating the atomizing core 192 passes through the delivery tube 17, the through-hole 152, the through-hole of the liquid absorbing material a, and the connection tube 111 (indicated by the broken-line arrow in fig. 3), and is then delivered from the mouth end of the mouthpiece 11, and is then sucked by the user.

The battery cell 20 is disposed between the lower end cap 16 and the base 13. The battery cell 20 provides electrical power for operating the electronic atomizing device 100. The battery cell 20 may be a rechargeable battery or a disposable battery. Rechargeable batteries are preferred.

The base 13 is provided with an air inlet, from which air outside the electronic atomizing device 100 can flow into the electronic atomizing device 100, and then flows into the atomizing core 192 from the through hole 162 of the lower end cover 16. Further, an air flow sensor may be provided on the base 13 for sensing the user's suction action to activate the atomizing core 192.

As shown in fig. 14, in another example, in order to prevent the liquid absorbing member a from absorbing the liquid matrix in the liquid storage chamber through the through-hole 154, causing the liquid matrix to leak through the through-hole 154 in the upper end cap 15, or in order to prevent the liquid absorbing member a from damaging the liquid sealing effect of the through-hole 154 in the upper end cap 15, causing the liquid matrix to leak through the through-hole 154 in the upper end cap 15, the liquid absorbing member a has a notched groove A1, through which the through-hole 154 in the upper end cap 15 can be avoided.

In a further embodiment, a space groove 155 is provided in the accommodation groove 153 of the upper end cover 15, and the space groove 155 is formed by a baffle plate protruding from the bottom surface of the accommodation groove 153. An opening at one end of the through-hole 154 is provided in the space groove 155, and the liquid absorbing member a is provided outside the space groove 155, for example, the liquid absorbing member a is provided at a lateral periphery of the space groove 155.

If the through hole 154 is provided in the lower end cap 16, the liquid absorbing member a and the corresponding notch groove A1 may be provided on the surface of the lower end cap 16 facing away from the liquid storage chamber.

As shown in fig. 15 to 16, in another example, the upper end cap 15 has a plurality of space grooves D on a surface facing the liquid storage chamber, the space grooves D are formed by recessing a portion of the surface of the liquid storage chamber, and an opening of one end of the through hole 154 may be provided in one of the space grooves D. Adjacent space grooves D are spaced apart from each other by the ribs 156 such that the plurality of space grooves D are spaced apart from each other in the circumferential direction of the receiving groove 153, are not communicated with each other, and are thus independent of each other. The plurality of space grooves D divide the surface of the upper end cover 15 facing the liquid storage chamber into a plurality of sections that are not communicated with each other, so that the liquid matrix in one space groove D is difficult to enter into the other space groove D, thereby being able to reduce the flow velocity of the liquid matrix on the surface of the upper end cover 15 facing the liquid storage chamber and helping to block the liquid matrix in the other space groove D from entering into one space groove D, and thus helping to reduce the amount of the liquid matrix in the space groove D. For one of the space grooves D provided with an opening at one end of the through-hole 154, the speed and amount of the liquid matrix entering the one of the space grooves D can be restricted, so that it helps to prevent leakage of the liquid matrix through the through-hole 154.

It should be noted that, if the through hole 154 is provided on the lower end cover 16, a plurality of space slots D may be provided on the surface of the lower end cover 16 facing the liquid storage chamber, and an opening at one end of the through hole 154 may be provided in one of the space slots D.

It should be noted that the description and drawings of the present application show preferred embodiments of the present application, but the present application may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, which are not to be construed as additional limitations on the content of the present application, but are provided for the purpose of providing a more thorough understanding of the present disclosure. The above-described features are further combined with each other to form various embodiments not listed above, and are considered to be the scope described in the present specification; further, modifications and variations of the present utility model may occur to those skilled in the art in light of the foregoing teachings, and all such modifications and variations are intended to be within the scope of the appended claims.
