[0027] The directional terms such as "up," "down," "left," "right," "front," "back," "top," and "bottom" (if present) used in the specification and claims of this utility model are defined according to the position of the structures in the drawings and the relative positions of the structures, and are only for the purpose of clarity and convenience in expressing the technical solution. It should be understood that the use of directional terms should not limit the scope of protection claimed by this utility model.

[0028] like Figures 1 to 4 and Figure 7 As shown, this utility model embodiment provides an electronic atomizer, including a housing 1, a liquid storage chamber 10, an atomizing component 2, and a delivery pump 3. The liquid storage chamber 10, the atomizing component 2, and the delivery pump 3 are all disposed inside the housing 1, and the atomizing component 2 is located above the liquid storage chamber 10.

[0029] The atomizing component 2 includes an atomizing core 21 and a liquid reservoir 22. The liquid reservoir 22 is used to store atomizing liquid, and the atomizing liquid (e.g., e-liquid) stored on the liquid reservoir 22 can be conducted to the atomizing core 21. The atomizing core 21 is used to heat up after being powered on to heat and atomize the atomizing liquid.

[0030] The storage chamber 10 is used to store atomized liquid. The delivery pump 3 has an inlet 31 and an outlet 32. The inlet 31 is connected to the storage chamber 10 through an inlet pipe 6, and the outlet 32 ​​is connected to the stored liquid 22 through an outlet pipe 7. The delivery pump 3 is used to pump the atomized liquid stored in the storage chamber 10 to the stored liquid 22. When the delivery pump 3 is powered on and running, it can draw the atomized liquid stored in the storage chamber 10 into the delivery pump 3 through the inlet pipe 6, and then pump the atomized liquid in the delivery pump 3 to the stored liquid 22 through the outlet pipe 7 (the atomized liquid in the inlet pipe 6 is drawn into the delivery pump 3 through the inlet 31 and discharged to the outlet pipe 7 through the outlet 32).

[0031] The electronic atomizer provided by the embodiment of the utility model, through setting up the delivery pump 3, the delivery pump 3 is used to pump the atomized liquid stored in the liquid storage cavity 10 to the liquid storage body 22, then the liquid storage body 22 conducts the atomized liquid to the atomizing core 21, so that the atomizing core 21 generates smoke by heating and atomizing. Compared with the traditional liquid supply mode using the gravity of the atomized liquid, the liquid supply mode using the delivery pump 3 can improve the liquid supply efficiency, ensure sufficient liquid supply and meet the liquid supply requirements in different use scenarios (for example, meet the requirements of continuous liquid supply for a long time); moreover, the liquid supply amount of the delivery pump 3 is controllable (by controlling the opening and closing of the delivery pump 3, the liquid supply amount of the delivery pump 3 can be controlled), thereby avoiding the delivery of too much atomized liquid to the liquid storage body 22, and further avoiding the problem of liquid leakage of the liquid storage body 22 and the atomizing core 21.

[0032] As shown in Figure 3 , Figure 4 and Figure 7 , as an embodiment, the liquid storage body 22 is a ring-shaped structure of liquid storage cotton (oil storage cotton), and the liquid storage body 22 is sleeved outside the atomizing core 21, so that the atomized liquid stored on the liquid storage body 22 can be conducted to the atomizing core 21.

[0033] Specifically, in the embodiment, the liquid supplementing hole 221 is a through hole penetrating the liquid storage body 22 from top to bottom (of course, in other embodiments, the liquid supplementing hole 221 can also be a blind hole not penetrating the liquid storage body 22; or the liquid supplementing hole 221 can extend in other directions, for example, the liquid supplementing hole 221 extends obliquely), and the liquid outlet pipe 7 is inserted into the liquid supplementing hole 221 from bottom to top, thereby avoiding liquid leakage; since the liquid storage body 22 is liquid storage cotton, after the delivery pump 3 pumps the atomized liquid into the liquid supplementing hole 221, the atomized liquid can be rapidly conducted to each position of the liquid storage cotton by using the liquid conducting function of the liquid storage cotton, thereby ensuring uniform liquid supply of the liquid storage cotton.

[0034] As shown in Figure 3 , Figure 4 and Figure 7 , as an embodiment, the atomizing core 21 includes a porous base body 211 and a heating body 212, the porous base body 211 is a hollow tubular structure, and the heating body 212 is arranged on the inner wall of the porous base body 211; the atomized liquid stored on the liquid storage body 22 can be conducted to the porous base body 211, and the heating body 212 generates heat after being electrified, thereby heating and atomizing the atomized liquid on the porous base body 211. The heating body 212 can be a heating net, a heating wire or the like. In the embodiment, the porous base body 211 is oil guiding cotton; of course, in other embodiments, the porous base body 211 can also be a porous ceramic body, a porous glass body or the like. In other embodiments, the atomizing core 21 can also have other structures.

[0035] As shown in Figure 3 , Figure 4 and Figure 7 , as an implementation form, the atomization assembly 2 further comprises an atomization tube 23, which can be a stainless steel tube or the like. The atomization tube 23 is sleeved outside the atomization core 21, and the liquid storage body 22 is sleeved outside the atomization tube 23. The atomization tube 23 is provided with a liquid guide hole 231 corresponding to the position of the atomization core 21, and the atomization liquid stored on the liquid storage body 22 can be conducted to the atomization core 21 through the liquid guide hole 231. The atomization tube 23 is used to fix and protect the atomization core 21, and can also play a role of guiding smoke (that is, the atomization tube 23 can guide the smoke generated on the atomization core 21 into the suction nozzle 17).

[0036] As shown in Figure 3 , Figure 4 and Figure 7 , as an implementation form, the atomization assembly 2 further comprises a transparent shell 24, and the atomization core 21 and the liquid storage body 22 are located in the transparent shell 24. The transparent shell 24 is a hollow cylindrical structure with open upper and lower ends. The upper end of the transparent shell 24 is provided with an upper silica gel 25, and the lower end of the transparent shell 24 is provided with a lower silica gel 26. The upper silica gel 25 and the lower silica gel 26 are used to seal the upper and lower ends of the transparent shell 24. The lower silica gel 26 is provided with a perforation 261, and the liquid outlet pipe 7 is inserted into the liquid supplementing hole 221 of the liquid storage body 22 after passing through the perforation 261.

[0037] As shown in Figure 3 , Figure 4 and Figure 7 , as an implementation form, the top of the shell 1 is provided with a suction nozzle 17 corresponding to the atomization assembly 2. The smoke generated on the atomization core 21 can flow into the suction nozzle 17 for the user to smoke. The upper silica gel 25 is provided with a groove 251, and the groove 251 is provided with an oil absorbing cotton 27. The oil absorbing cotton 27 is used to absorb the condensate generated after the smoke is condensed.

[0038] As shown in Figures 1 to 4 , as an implementation form, the shell 1 is provided with a window 13 (which is specifically provided on the upper shell 1A) corresponding to the position of the transparent shell 24. The window 13 is fixedly provided with a transparent cover plate 14, and the transparent cover plate 14 seals the window 13.

[0039] Specifically, since the transparent cover plate 14 and the transparent shell 24 are both transparent structures, the user can directly observe the liquid storage condition on the liquid storage body 22 through the window 13, so that the user can actively control the opening and closing of the delivery pump 3 according to the liquid storage condition of the liquid storage body 22 (for example, when the amount of atomized liquid on the liquid storage body 22 is observed to be relatively large, the delivery pump 3 can be actively controlled to be closed; or when the amount of atomized liquid on the liquid storage body 22 is observed to be relatively small, the delivery pump 3 can be actively controlled to be opened), and meanwhile, the electronic atomizer can have improved aesthetics, interest and technological sense. The transparent cover plate 14 and the transparent shell 24 can be made of transparent plastic, transparent glass or the like.

[0040] As shown in Figure 3 and Figure 4 , as an embodiment, one end of the liquid inlet pipe 6 is connected to the liquid inlet 31 of the delivery pump 3, and the other end (i.e. the lower end) of the liquid inlet pipe 6 extends into the bottom of the liquid storage cavity 10, and there is a gap 101 between the lower end of the liquid inlet pipe 6 and the inner bottom wall of the liquid storage cavity 10. In this way, since the liquid inlet pipe 6 extends into the bottom of the liquid storage cavity 10, the delivery pump 3 can suck the atomized liquid in the liquid storage cavity 10 as completely as possible through the liquid inlet pipe 6 during use, thereby improving the utilization rate of the atomized liquid; meanwhile, since there is a gap 101 between the lower end of the liquid inlet pipe 6 and the inner bottom wall of the liquid storage cavity 10, the atomized liquid in the liquid storage cavity 10 can enter the liquid inlet pipe 6 through the gap 101 to realize normal liquid suction function.

[0041] As shown in Figure 3 , Figure 4 and Figure 6 , as an embodiment, the delivery pump 3 is located above the liquid storage cavity 10. The shell 1 is provided with a sealing member 11, which is located between the atomization assembly 2, the delivery pump 3 and the liquid storage cavity 10, and is located above the liquid storage cavity 10.

The sealing member 11 can also be made of soft materials such as silica gel, and the sealing member 11 and the lower shell 1B can be sealed by interference fit or the like.

[0043] As shown in Figure 3 , Figure 4 and Figure 6 , as an embodiment, the liquid inlet pipe 6 includes a first liquid inlet pipe 61 and a second liquid inlet pipe 62, the first liquid inlet pipe 61 is arranged on the sealing member 11 and located in the liquid storage cavity 10, and the second liquid inlet pipe 62 is located above the sealing member 11.

[0045] As shown in Figures 3 to 5 and Figure 7 , as an embodiment, a support member 12 is fixedly arranged in the shell 1 (in the embodiment, the support member 12 is specifically fixed by clamping with the lower shell 1B, and the support member 12 abuts against the sealing member 11), the support member 12 is located between the atomization assembly 2, the delivery pump 3 and the liquid storage cavity 10, the support member 12 is located above the sealing member 11, and the atomization assembly 2 and the delivery pump 3 are arranged on the support member 12. The support member 12 can be specifically a plastic member.

[0046] The liquid outlet pipe 7 includes a first liquid guide pipe 71 and a second liquid guide pipe 72, the first liquid guide pipe 71 is arranged on the support member 12, and the second liquid guide pipe 72 is located below the support member 12.

The delivery pump 3 can sequentially pump the atomized liquid to the liquid storage body 22 through the second liquid guide pipe 72 and the first liquid guide pipe 71.

[0047] Specifically, in the present embodiment, the first liquid guide pipe 71 is arranged vertically, the lower end of the first liquid guide pipe 71 is connected with the support 12, and the upper end of the first liquid guide pipe 71 is inserted into the liquid supplement hole 221 of the liquid storage body 22 from bottom to top. The first liquid guide pipe 71 is located on the upper side of the support 12 and is in an integrated structure with the support 12. The first liquid guide pipe 71 is a hard pipe, and the support 12 is provided with a second convex pipe portion 122 in communication with the first liquid guide pipe 71, which is located below the first liquid guide pipe 71. The second liquid guide pipe 72 is a soft pipe, one end of the second liquid guide pipe 72 is fixedly connected with the liquid outlet 32 of the delivery pump 3, and the other end of the second liquid guide pipe 72 is fixedly connected with the second convex pipe portion 122, thereby facilitating assembly.

[0048] As shown in Figures 1 to 5 , as an embodiment, the support 12 is provided with an extension portion 121 corresponding to the window 13 on the shell 1, and the transparent cover plate 14 is fixed (specifically, fixed by clamping) with the extension portion 121.

[0049] As shown in Figures 1 to 4 , as an embodiment, the side wall of the shell 1 is provided with an air inlet hole 15 (the air inlet hole 15 is specifically arranged on the upper shell 1A), and the shell 1 is provided with an air flow channel 16, the air inlet hole 15 is in communication with the atomization core 21 through the air flow channel 16 (specifically, in communication with the inner cavity of the porous base 211), so that the external air can reach the atomization core 21 through the air inlet hole 15 and the air flow channel 16 in sequence.

[0050] As shown in Figures 1 to 4 , as an embodiment, the electronic atomizer further comprises an electronic control assembly 4 and a power supply assembly 5 arranged in the shell 1 (the electronic control assembly 4 and the power supply assembly 5 are specifically arranged in the upper shell 1A), the electronic control assembly 4 specifically comprises a circuit board (not labeled in the figure) and electronic elements arranged on the circuit board, and the power supply assembly 5 comprises a battery; the electronic control assembly 4 and the power supply assembly 5 are both located above the liquid storage cavity 10. Since the atomization assembly 2, the delivery pump 3, the electronic control assembly 4 and the power supply assembly 5 are all arranged above the liquid storage cavity 10, the setting space of the liquid storage cavity 10 can be avoided, the liquid storage cavity 10 can be arranged larger, and more atomization liquid can be stored.

[0051] The electronic control assembly 4 is electrically connected with the atomization core 21, the delivery pump 3 and the power supply assembly 5 (specifically, electrically connected with the heating body 212) respectively. The power supply assembly 5 is used for supplying power to each component, and the electronic control assembly 4 is used for controlling the work of each component. The electronic control assembly 4 is used for controlling the opening and closing of the delivery pump 3 and the atomization core 21 (that is, controlling whether the delivery pump 3 and the atomization core 21 are connected to the power supply).

[0052] In one implementation, the electronic control component 4 records the working time of the atomizing core 21 (specifically, the cumulative working time of the atomizing core 21 since the last time the delivery pump 3 was turned on), and controls the opening and closing of the delivery pump 3 based on the working time of the atomizing core 21. For example, when the cumulative working time of the atomizing core 21 since the last time the delivery pump 3 was turned on reaches a preset value (e.g., 5 minutes), the electronic control component 4 controls the delivery pump 3 to turn on for a period of time (e.g., 10 seconds) to replenish the storage liquid 22, and then controls the delivery pump 3 to turn off. This ensures the liquid supply balance of the storage liquid 22 (i.e., ensuring that there is sufficient atomized liquid on the storage liquid 22, without leakage due to excessive atomized liquid).

[0053] Specifically, in this embodiment, a pressure sensing element 43 (i.e., a microphone) is provided in the airflow channel 16, and the electronic control component 4 is electrically connected to the pressure sensing element 43. The electronic control component 4 is used to control the opening and closing of the atomizing core 21 according to the opening and closing of the pressure sensing element 43. During inhalation, the gas in the airflow channel 16 can be drawn to the atomizing core 21, causing the air pressure in the airflow channel 16 to decrease (at this time, the airflow channel 16 is generally under negative pressure). After sensing the change in air pressure, the pressure sensing element 43 opens, and the electronic control component 4 controls the atomizing core 21 to be energized, so that the atomizing core 21 works; that is, the pressure sensing element 43 can act as a switch. When the pressure sensing element 43 is open, the electronic control component 4 controls the atomizing core 21 to open; when the pressure sensing element 43 is closed, the electronic control component 4 controls the atomizing core 21 to close. The specific working principle of the pressure sensing element 43 can be found in the prior art, and will not be elaborated here.

[0054] The electronic control component 4 is also used to calculate the working time of the atomizing core 21 (the working time of the atomizing core 21 is also the working time of the atomizing core 21) based on the opening duration of the pressure sensing element 43 (specifically, the cumulative opening duration of the pressure sensing element 43 since the last opening of the delivery pump 3), and then control the opening and closing of the delivery pump 3. For example, when the cumulative opening duration of the pressure sensing element 43 since the last opening of the delivery pump 3 reaches a preset value (e.g., 5 minutes), the electronic control component 4 controls the delivery pump 3 to open for a period of time (e.g., 10 seconds) to replenish the storage liquid 22, and then controls the delivery pump 3 to close.

[0055] like Figures 1 to 4 As shown, in one embodiment, the delivery pump 3 and the power supply component 5 are located on one side of the atomizing component 2, and the delivery pump 3 is located between the power supply component 5 and the atomizing component 2; the electronic control component 4 is located on the side of the atomizing component 2 away from the delivery pump 3. Of course, in other embodiments, the atomizing component 2, the delivery pump 3, the electronic control component 4, and the power supply component 5 can also be arranged in other ways.

[0056] like Figures 1 to 4As shown, as an embodiment, the electric control assembly 4 is provided with a control button 41 and a charging interface 42, both of which are electrically connected with the electric control assembly 4. The control button 41 extends out of the shell 1 through the air inlet hole 15; by pressing the control button 41, the working mode of the electronic atomizer (for example, the size of the smoke output of the electronic atomizer) can be adjusted. The shell 1 is provided with a charging hole 18 at a position corresponding to the charging interface 42, so that the charging interface 42 is exposed through the charging hole 18; the charging interface 42 is used for charging the power supply assembly 5.

[0057] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
