Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, and in particular to a piezoelectric pump mounting structure, a liquid supply component, and an aerosol generation device. Background Technology

[0002] In the process of manufacturing aerosol generating devices, in order to facilitate the delivery of the aerosol generating matrix in the storage chamber to the atomizing core assembly, a piezoelectric pump is often set up to deliver the aerosol generating matrix. The piezoelectric pump has an input end and an output end. The input end is connected to the storage chamber, and the output end is connected to the atomizing core assembly. The piezoelectric pump also has a piezoelectric vibrator inside.

[0003] During the use of aerosol generation devices, the aerosol generation matrix in the storage chamber is generally transported to the atomizing core component by the vibration and deformation of the piezoelectric oscillator of the piezoelectric pump. However, the driving force of the piezoelectric pump on the aerosol generation matrix is ​​prone to decrease, resulting in a reduction in pumping efficiency. Utility Model Content

[0004] This application provides a piezoelectric pump mounting structure, a liquid supply component, and an aerosol generating device to improve the problem that the driving force of the piezoelectric pump on the aerosol generating matrix decreases and the pumping efficiency decreases during the use of the aerosol generating device.

[0005] In a first aspect, embodiments of this application provide a piezoelectric pump mounting structure, including a piezoelectric pump and a connector. The piezoelectric pump has a piezoelectric vibrator inside, and the connector is connected to the piezoelectric pump. At least one of the piezoelectric pump and the connector has a recess. The vibration zone of the piezoelectric vibrator is correspondingly provided with the recess. The recess is used to allow the piezoelectric pump and the connector to be spaced apart at the recess.

[0006] The piezoelectric pump mounting structure provided in this application embodiment has at least the following beneficial effects: Because the piezoelectric pump has a piezoelectric vibrator inside, and the connector is connected to the piezoelectric pump, and at least one of the piezoelectric pump and the connector has a recess, and the vibration zone of the piezoelectric vibrator is set corresponding to the recess, the piezoelectric pump and the connector can be spaced apart at the recess. This avoids a large part of the vibration of the piezoelectric vibrator inside the piezoelectric pump being transmitted to the connector, reducing the energy loss of the piezoelectric vibrator and making it less likely for the driving force of the piezoelectric pump to the aerosol generation matrix to decrease and the pumping efficiency to decrease.

[0007] In some embodiments, the recess is configured as a blind hole or a blind groove.

[0008] In some embodiments, the depth of the recess is 0.05mm-0.50mm.

[0009] In some embodiments, the length and / or width of the recess is 0.2 mm–1.0 mm.

[0010] In some of these embodiments, the recess is coaxially arranged with the piezoelectric vibrator.

[0011] In some embodiments, the connector is provided with a limiting groove, the recess is provided on the bottom surface of the limiting groove, the recess has an opening formed on the bottom surface of the limiting groove, and the piezoelectric pump is housed in the limiting groove and covers the opening.

[0012] In some embodiments, the bottom surface of the limiting groove is in contact with the outer surface of the piezoelectric pump.

[0013] In some embodiments, the connector is provided with a clearance groove that penetrates the sidewall of the limiting groove; the piezoelectric pump mounting structure also includes a circuit board that is connected to and electrically conductive with the piezoelectric pump, and the circuit board extends through the clearance groove to the external space of the connector.

[0014] Secondly, embodiments of this application provide a liquid supply component, including: Atomizer core assembly; A liquid storage device is provided with a liquid storage chamber, which is used to store the aerosol generation matrix; As described in the first aspect, the piezoelectric pump is used to deliver the aerosol generating matrix to the atomizing core assembly.

[0015] The liquid supply component provided in this application embodiment has at least the following beneficial effects: Because the piezoelectric pump has a piezoelectric vibrator inside, and the connector is connected to the piezoelectric pump, and at least one of the piezoelectric pump and the connector has a recess, and the vibration zone of the piezoelectric vibrator is set corresponding to the recess, the piezoelectric pump and the connector can be spaced apart at the recess. This avoids a large part of the vibration of the piezoelectric vibrator inside the piezoelectric pump being transmitted to the connector, reducing the energy loss of the piezoelectric vibrator and making it less likely for the driving force of the piezoelectric pump to the aerosol generation matrix to decrease and the pumping efficiency to decrease.

[0016] In some embodiments, the piezoelectric pump is located on one side of the liquid storage device, and the connector is located on the side of the piezoelectric pump opposite to the liquid storage device; the piezoelectric pump has an input end and an output end, the input end is connected to the liquid storage chamber, and the output end is connected to the atomizing core assembly.

[0017] Thirdly, embodiments of this application provide an aerosol generating device, which includes a liquid supply component as described in the second aspect.

[0018] The aerosol generating apparatus provided in this application has at least the following beneficial effects: Because the piezoelectric pump has a piezoelectric vibrator inside, and the connector is connected to the piezoelectric pump, and at least one of the piezoelectric pump and the connector has a recess, and the vibration zone of the piezoelectric vibrator is set corresponding to the recess, the piezoelectric pump and the connector can be spaced apart at the recess. This avoids a large part of the vibration of the piezoelectric vibrator inside the piezoelectric pump being transmitted to the connector, reducing the energy loss of the piezoelectric vibrator and making it less likely for the driving force of the piezoelectric pump to the aerosol generation matrix to decrease and the pumping efficiency to decrease.

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0023] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0025] In this specification, references to "one embodiment," "some embodiments," or simply "embodiment" mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. Furthermore, in one or more embodiments, specific features, structures, or characteristics may be combined in any suitable manner.

[0026] In the process of manufacturing aerosol generating devices, in order to facilitate the delivery of the aerosol generating matrix in the storage chamber to the atomizing core assembly, a piezoelectric pump is often set up to deliver the aerosol generating matrix. The piezoelectric pump has an input end and an output end. The input end is connected to the storage chamber, and the output end is connected to the atomizing core assembly. The piezoelectric pump also has a piezoelectric vibrator inside.

[0027] In the use of aerosol generation devices, the aerosol generation matrix in the storage chamber is generally transported to the atomizing core assembly by the vibration and deformation of the piezoelectric vibrator of the piezoelectric pump. For example, when the piezoelectric vibrator is a piezoelectric ceramic sheet, it will vibrate at a high frequency of tens to hundreds of kHz during operation, with an amplitude in the range of 1 micrometer to 10 micrometers.

[0028] When installing a piezoelectric pump, if the valve body or housing structure of the pump directly contacts the vibration zone of the piezoelectric oscillator against the external structure, some of the piezoelectric oscillator's vibrations will be absorbed by the external structure, causing energy attenuation. This can lead to a decrease in the driving force of the piezoelectric pump on the aerosol-generating matrix, resulting in reduced pumping efficiency. Simultaneously, it can cause nonlinear interference to the piezoelectric oscillator, leading to unstable flow rates or liquid blockage, making it difficult to achieve metered liquid supply. Furthermore, the long-term superimposed stress from micro-vibrations between the piezoelectric pump and the external structure may cause cracks or delamination in the piezoelectric oscillator, posing a risk of structural damage.

[0029] In view of this, this application provides a piezoelectric pump mounting structure, a liquid supply component, and an aerosol generating device. The piezoelectric pump mounting structure includes a piezoelectric pump and a connector. A piezoelectric vibrator is disposed inside the piezoelectric pump. The connector is connected to the piezoelectric pump. At least one of the piezoelectric pump and the connector is provided with a recess. The recess is provided corresponding to the piezoelectric vibrator. The recess is used to allow the piezoelectric pump and the connector to be spaced apart at the recess.

[0030] The piezoelectric pump mounting structure provided in this application embodiment has a piezoelectric vibrator inside the piezoelectric pump. The connector is connected to the piezoelectric pump, and at least one of the piezoelectric pump and the connector has a recess. The vibration zone of the piezoelectric vibrator is correspondingly arranged with the recess. Therefore, the piezoelectric pump and the connector are spaced apart at the recess, which can prevent a large part of the vibration of the piezoelectric vibrator inside the piezoelectric pump from being transmitted to the connector, reducing the energy loss of the piezoelectric vibrator and making it less likely for the driving force of the piezoelectric pump to the aerosol generation matrix to decrease and the pumping efficiency to decrease.

[0031] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0032] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 1This is a schematic diagram of the structure of the aerosol generating device 100 in one embodiment of this application. Figure 2 yes Figure 1 The diagram shows a top view of the aerosol generating device 100. Figure 3 yes Figure 2 The aerosol generating apparatus 100 shown is a cross-sectional view along the MM direction. Figure 4 yes Figure 3 A magnified view of a portion of point A in the middle.

[0033] In a first aspect, embodiments of this application provide a piezoelectric pump mounting structure that can be used in an aerosol generating device 100.

[0034] Please see Figure 4 The piezoelectric pump mounting structure includes a piezoelectric pump 10 and a connector 20. The piezoelectric pump 10 has a piezoelectric vibrator 11 inside, and the connector 20 is connected to the piezoelectric pump 10.

[0035] The piezoelectric vibrator 11 can be a piezoelectric ceramic sheet, or it can be made of piezoelectric polymer materials or piezoelectric composite materials. The connector 20 can be connected to the piezoelectric pump 10 by means of bonding, snap-fitting, welding, bolting, screwing, or clipping. The ceramic valve body or the outer casing of the piezoelectric pump 10 is connected to the connector 20.

[0036] By applying an AC voltage to the piezoelectric vibrator 11, the piezoelectric vibrator 11 can bend and vibrate, thereby increasing or decreasing the volume of the pump chamber of the piezoelectric pump 10.

[0037] Please refer to this as well. Figure 5 , Figure 6 , Figure 7 and Figure 8 , Figure 5 yes Figure 3 The diagram shown illustrates the connection principle of the piezoelectric pump 10 and the connector 20 in the aerosol generating device 100. Figure 6 yes Figure 3 The diagram shows the structure of the piezoelectric pump 10, connector 20, and circuit board 30 in the aerosol generating device 100. Figure 7 yes Figure 6 The schematic diagram of the piezoelectric pump 10 and the connector 20 shown is as follows. Figure 8 yes Figure 7 The top view of the connector 20 shown.

[0038] At least one of the piezoelectric pump 10 and the connector 20 is provided with a recess 201, and the vibration zone 111 of the piezoelectric vibrator 11 is provided corresponding to the recess 201. The recess 201 is used to make the piezoelectric pump 10 and the connector 20 spaced apart at the recess 201.

[0039] The vibration zone 111 of the piezoelectric vibrator 11 is the vibration part of the piezoelectric vibrator 11. Figure 5 The structure of the slightly reduced pressure electric pump 10 has been simplified.

[0040] The recess 201 can be a hole, such as a blind hole or a through hole. The recess 201 can also be a groove, such as a blind groove or a through groove. The recess 201 can also be a cavity. The shape of the recess 201 can be annular, strip-shaped, or other shapes. For example, when the recess 201 is a groove, it can be a straight groove, an annular groove, or an interlaced groove.

[0041] It should be noted that the presence of a recess 201 in at least one of the piezoelectric pump 10 and the connector 20 can be: the piezoelectric pump 10 has a recess 201, while the connector 20 does not; or the piezoelectric pump 10 does not have a recess 201, while the connector 20 has a recess 201; or both the piezoelectric pump 10 and the connector 20 have recesses 201.

[0042] It is understandable that when the piezoelectric pump 10 is provided with a recess 201, the recess 201 can be provided in the ceramic valve body or the outer shell of the piezoelectric pump 10. The piezoelectric pump 10 and the connector 20 are spaced apart at the recess 201, and other parts of the piezoelectric pump 10 and other parts of the connector 20 are connected except for the recess 201. The vibration zone 111 of the piezoelectric vibrator 11 is correspondingly provided with the recess 201, and the non-vibration zone 111 of the piezoelectric vibrator 11 is still fixed to the pump cavity by a sealing ring or adhesive to ensure overall sealing.

[0043] Since the recess 201 is used to allow the piezoelectric pump 10 and the connector 20 to be spaced apart at the recess 201, the vibration transmitted from the piezoelectric vibrator 11 to the connector 20 can be reduced, thereby reducing the energy loss of the piezoelectric vibrator 11 and making it less likely that the driving force of the piezoelectric pump 10 on the aerosol generation matrix will decrease and the pumping efficiency will be reduced.

[0044] As can be seen from the above, the piezoelectric pump installation structure provided in this application embodiment has a piezoelectric vibrator 11 inside the piezoelectric pump 10, and the connector 20 is connected to the piezoelectric pump 10. At least one of the piezoelectric pump 10 and the connector 20 is provided with a recess 201, and the vibration zone 111 of the piezoelectric vibrator 11 is correspondingly provided with the recess 201. Therefore, the piezoelectric pump 10 and the connector 20 are spaced apart at the recess 201 through the recess 201, thereby avoiding the transmission of a large part of the vibration of the piezoelectric vibrator 11 inside the piezoelectric pump 10 to the connector 20, reducing the energy loss of the piezoelectric vibrator 11, improving the stability of the pump fluid flow, and making it less likely for the driving force of the piezoelectric pump 10 to the aerosol generation matrix to decrease and the pumping efficiency to decrease.

[0045] It is understood that in the piezoelectric pump installation structure provided in this application embodiment, the piezoelectric pump 10 is not prone to unstable flow or liquid blockage, can achieve quantitative liquid supply, and reduces stress concentration and mechanical damping, reduces the risk of fatigue damage to the piezoelectric oscillator 11, the structure is not easily damaged, and the service life is extended. At the same time, the structure is compact and does not require a significant increase in parts or buffer layers to achieve energy isolation between the connector 20 and the piezoelectric pump 10.

[0046] Please refer to Figures 3 to 8 In some of these embodiments, the recess 201 is configured as a blind hole or a blind groove.

[0047] By adopting the above solution, it is possible to ensure that the piezoelectric pump 10 and the connector 20 are spaced apart at the recess 201, while ensuring that the piezoelectric pump 10 and / or connector 20 with the recess 201 have high strength.

[0048] It is understandable that the piezoelectric pump 10 is provided with a recess 201. When the recess 201 is set as a blind hole or blind groove, it can ensure that the piezoelectric pump 10 and the connector 20 are spaced apart at the recess 201 while ensuring that the piezoelectric pump 10 has high strength. Similarly, when the connector 20 is provided with a recess 201, and the recess 201 is set as a blind hole or blind groove, it can ensure that the piezoelectric pump 10 and the connector 20 are spaced apart at the recess 201 while ensuring that the connector 20 has high strength.

[0049] Optionally, the depth of the recess 201 is 0.05mm-0.50mm, such as 0.05mm, 0.15mm, 0.25mm, 0.40mm or 0.50mm.

[0050] This arrangement ensures that the piezoelectric pump 10 and the connector 20 are spaced apart at the recess 201, preventing a large portion of the vibration of the piezoelectric vibrator 11 in the piezoelectric pump 10 from being transmitted to the connector 20. It also ensures that the piezoelectric pump 10 and / or the connector 20 with the recess 201 have high strength.

[0051] Understandably, the position, shape, and depth of the recess 201 can be optimized according to the vibration mode of the piezoelectric vibrator 11, as long as it does not affect the vibration of the piezoelectric vibrator 11 itself. By adjusting the size of the recess 201, piezoelectric vibrators 11 of different thicknesses (such as 0.1 mm to 0.5 mm) can be accommodated.

[0052] Optionally, the length and / or width of the recess 201 are 0.2mm–1.0mm, such as 0.2mm, 0.5mm, 0.6mm, 0.8mm or 1.0mm.

[0053] This arrangement ensures that the piezoelectric pump 10 and the connector 20 are spaced apart at the recess 201, preventing a large portion of the vibration of the piezoelectric vibrator 11 inside the piezoelectric pump 10 from being transmitted to the connector 20.

[0054] Optionally, the recess 201 is coaxially arranged with the piezoelectric vibrator 11.

[0055] This configuration makes it easier to control the relative position of the connector 20 and the piezoelectric pump 10.

[0056] It is understandable that the axis of the recess 201 is collinear with the axis of the piezoelectric vibrator 11.

[0057] As one possible implementation method, the recess 201 is configured as a cylindrical groove, and the piezoelectric vibrator 11 is configured as a disc.

[0058] Please refer to Figures 3 to 8 In some embodiments, the connector 20 is provided with a limiting groove 202, and a recess 201 is provided on the bottom surface of the limiting groove 202. The recess 201 has an opening formed on the bottom surface of the limiting groove 202, and the piezoelectric pump 10 is housed in the limiting groove 202 and covers the opening.

[0059] By adopting the above solution, it is easy to connect the connector 20 to the piezoelectric pump 10, and the recessed part 201 can prevent most of the vibration of the piezoelectric vibrator 11 from being transmitted to the bottom surface of the limiting groove 202 and then to the connector 20.

[0060] Understandably, in order to avoid a large portion of the vibration of the piezoelectric vibrator 11 being transmitted to the side of the limiting groove 202, the piezoelectric pump 10 can be spaced apart from the side of the limiting groove 202, or the non-vibration area 111 of the piezoelectric pump 10 can be fitted to the side of the limiting groove 202.

[0061] Optionally, the bottom surface of the limiting groove 202 is in contact with the outer surface of the piezoelectric pump 10.

[0062] This configuration not only enables the connection between the connector 20 and the piezoelectric pump 10, but also prevents a large portion of the vibration of the piezoelectric vibrator 11 from being transmitted to the bottom surface of the limiting groove 202 and then to the connector 20 through the recessed portion 201.

[0063] Optionally, the connector 20 is provided with a clearance groove 203, which penetrates the side wall of the limiting groove 202; the piezoelectric pump mounting structure also includes a circuit board 30, which is connected to and electrically conductive with the piezoelectric pump 10, and the circuit board 30 extends through the clearance groove 203 to the external space of the connector 20.

[0064] With this configuration, the circuit board 30 can be routed to the external space of the connector 20 through the recess 203.

[0065] It should be noted that circuit board 30 can be FPC (Flexible Printed Circuit Board).

[0066] Please refer to Figures 1 to 8 Secondly, embodiments of this application provide a liquid supply component, including an atomizing core assembly 40, a liquid storage component 50, and a piezoelectric pump mounting structure as described in the first aspect.

[0067] The liquid storage component 50 is provided with a liquid storage chamber 51, which is used to store the aerosol generation matrix.

[0068] The piezoelectric pump 10 is used to deliver the aerosol generation matrix to the atomizing core assembly 40.

[0069] The liquid supply component provided in this application embodiment has a piezoelectric vibrator 11 inside the piezoelectric pump 10, and the connector 20 is connected to the piezoelectric pump 10. At least one of the piezoelectric pump 10 and the connector 20 is provided with a recess 201. The vibration zone 111 of the piezoelectric vibrator 11 is correspondingly provided with the recess 201. Therefore, the piezoelectric pump 10 and the connector 20 are spaced apart at the recess 201 through the recess 201. This avoids a large part of the vibration of the piezoelectric vibrator 11 inside the piezoelectric pump 10 being transmitted to the connector 20, reducing the energy loss of the piezoelectric vibrator 11, and making it less likely that the driving force of the piezoelectric pump 10 on the aerosol generation matrix will decrease and the pumping efficiency will decrease.

[0070] Optionally, the piezoelectric pump 10 is located on one side of the liquid storage unit 50, and the connector 20 is located on the side of the piezoelectric pump 10 away from the liquid storage unit 50; the piezoelectric pump 10 has an input end and an output end, the input end is connected to the liquid storage chamber 51, and the output end is connected to the atomizing core assembly 40.

[0071] This design allows for a more compact structure in the liquid supply components.

[0072] It is understood that the atomizing core assembly 40 may include a liquid storage cotton and an atomizing core. The aerosol generating matrix in the liquid storage chamber 51 can enter the interior of the piezoelectric pump 10 through the input end. The piezoelectric oscillator 11 of the piezoelectric pump 10 vibrates and deforms, and the deformation generates a change in the volume of the pump chamber, so that the aerosol generating matrix is ​​output from the output end to the liquid storage cotton.

[0073] Thirdly, embodiments of this application provide an aerosol generating apparatus 100, which includes a liquid supply component as described in the second aspect.

[0074] The aerosol generating apparatus 100 provided in this application embodiment has a piezoelectric vibrator 11 inside the piezoelectric pump 10, and a connector 20 connected to the piezoelectric pump 10. At least one of the piezoelectric pump 10 and the connector 20 is provided with a recess 201. The vibration zone 111 of the piezoelectric vibrator 11 is correspondingly provided with the recess 201. Therefore, the piezoelectric pump 10 and the connector 20 are spaced apart at the recess 201 through the recess 201. This avoids a large part of the vibration of the piezoelectric vibrator 11 inside the piezoelectric pump 10 being transmitted to the connector 20, reducing the energy loss of the piezoelectric vibrator 11, and making it less likely that the driving force of the piezoelectric pump 10 on the aerosol generating matrix will decrease and the pumping efficiency will decrease.

[0075] It is understood that the aerosol generating device 100 provided in the embodiments of this application may also include a housing 60, a power supply component and other sealing components, etc. The piezoelectric pump 10, connector 20, atomizing core assembly 40, liquid storage component 50, power supply component and other sealing components are all disposed inside the housing 60, and will not be described in detail here.

[0076] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
