[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0034] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0035] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0036] Please combine them together Figures 1 to 14 The electronic cigarette provided by this utility model will now be described.

[0037] The electronic cigarette includes: a shell 1, an atomizing component 2, a piezoelectric micropump 3, and a flexible pouch 4. The shell 1 has a receiving space 100. The atomizing component 2 is fixed in the receiving space 100. The flexible pouch 4 is used to store e-liquid. The piezoelectric micropump 3 connects the flexible pouch 4 and the atomizing component 2 and is used to pump the e-liquid in the flexible pouch 4 to the atomizing component 2. The flexible pouch 4 gradually shrinks as the e-liquid is consumed, avoiding the generation of air bubbles after air enters the oil tank in the prior art, and preventing negative pressure, thus ensuring stable oil pumping.

[0038] It should be noted that the flexible bag 4 can be an infusion bag, a sealing bag, or a food-grade heat-sealing bag. Using this method for oil storage is low-cost and easy to install. The four corners of the flexible bag 4 are attached to the housing 1 within the accommodating space 100.

[0039] In this embodiment, the flexible bag 4 and the piezoelectric micropump 3 have multiple communication methods: In one embodiment, three adjacent sides of the four sides of the flexible bag 4 are sealed, and the piezoelectric micropump 3 is connected to the unsealed side. That is, the flexible bag has no tube 42. In this way, the oil inlet pipe 31 of the piezoelectric micropump 3 can be connected to the unsealed side, so that the piezoelectric micropump 3 can pump the e-liquid in the flexible bag 4 into the atomizing assembly 2.

[0040] In another embodiment, the flexible bag 4 includes a bag body 41 and a tube 42 connected to the bag body 41. A seal 421 is provided inside the tube 42. The piezoelectric micropump 3 punctures the seal 421 and connects to the bag body 41. After the oil inlet tube 31 of the piezoelectric micropump 3 punctures the seal 421, it connects to the bag body 41, allowing the piezoelectric micropump 3 to pump the e-liquid in the bag body 41 into the atomizing assembly 2. By providing the seal 421, the e-liquid in the bag body 41 will not flow out through the tube 42.

[0041] Furthermore, the bag body 41 is provided with a hanging opening 411, which is used to hang the bag body 41 inside the accommodating space 100. In this way, the bag body 41 can be hung upright on the shell 1 inside the accommodating space 100, which is beneficial for the disassembly and replacement of the flexible bag 4.

[0042] Furthermore, the flexible bag 4 can be square or irregularly shaped. A square flexible bag 4 increases capacity. An irregularly shaped flexible bag 4 increases the utilization of structural space.

[0043] In one embodiment, such as Figure 6 and Figure 13 As shown, the piezoelectric micropump 3 includes an oil inlet pipe 31, an oil outlet pipe 32, a first mounting base 33, a first partition 34, a valve plate 35, a second partition 36, a second mounting base 37, a deformable diaphragm 38, and a drive plate 39. The first mounting base 33, the first partition 34, the valve plate 35, the second partition 36, the second mounting base 37, the deformable diaphragm 38, and the drive plate 39 are connected sequentially. The second mounting base 37 has a pump chamber 200. The first mounting base 33, the first partition 34, the valve plate 35, the second partition 36, and the second mounting base 37 all have an oil inlet channel 300 and an oil outlet channel 400 that communicate with the pump chamber 200. The oil inlet pipe 31 connects the flexible bag 4 to the oil inlet channel 300, and the oil outlet pipe 32 connects the atomizing component 2 to the oil outlet channel 400. Specifically, the valve plate 35 is made of PET, and the drive plate 39 is made of PZT piezoelectric ceramic. When the drive plate 39 is energized, it deforms, causing the diaphragm to deform and reducing or increasing the volume of the pump chamber 200, thereby creating a negative or positive pressure. This pressure drives the e-liquid from the inlet pipe 31 through the inlet channel 300 into the pump chamber 200. The e-liquid in the pump chamber 200 then flows out through the outlet channel 400 and out through the outlet pipe 32. The first mounting base 33 facilitates the fixation of the piezoelectric micropump 3.

[0044] In this embodiment, the oil inlet pipe 31 and the oil outlet pipe 32 are arranged in the same direction or in different directions. The arrangement direction of the oil inlet pipe 31 and the oil outlet pipe 32 can be set according to the structure, which is highly flexible and helps in structural design.

[0045] In one embodiment, such as Figure 10As shown, there are two piezoelectric micropumps 3, which are mirror images of each other with the drive plate 39 as the axis. This makes the piezoelectric micropumps 3 form a dual-channel configuration, specifically, there are two oil inlet pipes 31 and two oil outlet pipes 32, which can increase the oil inflow and outflow.

[0046] In one embodiment, such as Figure 11 As shown, at least two piezoelectric micropumps 3 are provided, with the oil outlet pipe 32 of one piezoelectric micropump 3 connected to the oil inlet pipe 31 of the other piezoelectric micropump 3. In this way, the two piezoelectric micropumps 3 are connected in series, which can increase the power.

[0047] Of course, in other embodiments, the oil outlet pipe 32 of one piezoelectric micropump 3 can be eliminated, and the oil inlet pipe 31 of the other piezoelectric micropump 3 can be eliminated, so that the oil outlet channel 400 of one piezoelectric micropump 3 is directly connected to the oil inlet channel 300 of the other piezoelectric micropump 3, thereby reducing the volume.

[0048] In one embodiment, such as Figure 12 and Figure 13 As shown, the electronic cigarette also includes a fixed housing 5, a first pipe 6, and a second pipe 7. Two piezoelectric micropumps 3 are provided, fixed together by the fixed housing 5 and symmetrically arranged. The oil inlet pipes 31 of the two piezoelectric micropumps 3 are interconnected, as are the oil outlet pipes 32 of the two piezoelectric micropumps 3. The first pipe 6 connects to the oil inlet pipe 31, and the second pipe 7 connects to the oil outlet pipe 32. This allows the two piezoelectric micropumps 3 to be connected in parallel, increasing power.

[0049] Specifically, when the two piezoelectric micropumps 3 are working, oil enters from the first pipe 6 into the oil inlet pipe 31, and then the e-liquid in the oil inlet pipe 31 flows into the pump chamber 200 through the oil inlet channel 300. The e-liquid in the pump chamber 200 then enters the oil outlet pipe 32 through the oil outlet channel 400, and then flows out through the second pipe 7.

[0050] In one embodiment, such as Figure 14As shown, the piezoelectric micropump 3 includes an oil inlet pipe 31, an oil outlet pipe 32, a first mounting base 33, a first partition 34, a second partition 36, a second mounting base 37, a deformable film 38, and a drive plate 39. The first mounting base 33, the first partition 34, the second partition 36, the second mounting base 37, the deformable film 38, and the drive plate 39 are connected in sequence. The second mounting base 37 has a pump chamber 200. The first mounting base 33, the first partition 34, the second partition 36, and the second mounting base 37 all have an oil inlet channel 300 and an oil outlet channel 400 that communicate with the pump chamber 200. The oil inlet pipe 31 connects the flexible bag 4 and the oil inlet channel 300, and the oil outlet pipe 32 connects the atomizing component 2 and the oil outlet channel 400. Specifically, the drive plate 39 is made of PZT piezoelectric ceramic. When the drive plate 39 is energized, it deforms, causing the diaphragm to deform and reducing or increasing the volume of the pump chamber 200, thereby creating negative or positive pressure. This pressure drives the e-liquid from the inlet pipe 31 through the inlet channel 300 into the pump chamber 200. The e-liquid in the pump chamber 200 then flows out through the outlet channel 400 and out through the outlet pipe 32. The first mounting base 33 facilitates the fixation of the piezoelectric micropump 3. In addition, the valve plate 35 is eliminated to prevent the valve plate 35 from clogging the orifice.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
