Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.
Referring to fig. 1 and 2 together, a perspective view and another perspective view of the aerosol generating device 1 are shown, respectively. The aerosol-generating device 1 comprises a metal sheet 100 and a piezoelectric transducer 200. The metal sheet 100 is connected to a piezoelectric transducer 200. The metal sheet 100 is provided with a guide hole. The piezoelectric transducer 200 is provided with a positive terminal 210, and the metal sheet 100 is provided with a negative terminal lug 120 for connecting the aerosol generating device to a circuit. The piezoelectric transducer 200 converts the electric energy into mechanical energy, and the piezoelectric transducer 200 vibrates, thereby driving the metal sheet 100 to vibrate. The tension between the test liquids is broken by the metal sheet 100 to generate aerosol, which is ejected through the piezoelectric transducer 200 after passing through the flow guide hole (not shown) and vibrating at the same frequency.
As shown in fig. 1, the metal sheet 100 is divided into a first surface 101 and a second surface 102, the first surface 101 is provided with a groove 110, the groove 110 is formed by recessing from the first surface 101 to the second surface 102 of the metal sheet 100, and the second surface 102 is regarded as a protrusion. The groove 110 includes sidewalls 111 and a groove bottom 112. The side wall 111 is a conical surface, the groove bottom 112 is a planar surface, and the area of the cross section of the groove 110 gradually decreases from the first surface 101 to the second surface 102 of the metal sheet 100. The angle between the sidewall of the groove 110 and the central axis of the groove 110 is in the range of 2.5 degrees to 87.5 degrees, and the aerosol vibrating to the second surface 102 has a spraying force.
Further, the vertical height of the notch of the groove 110 to the groove bottom of the groove 110 is greater than 0.1 mm. The height drop exists, so that the liquid medicine can be fully contacted with the groove 110 on one hand, the damage to the surface tension of the liquid is facilitated, on the other hand, the axial distance of the side wall of the groove 110 is lengthened, the aerosol continuously obtains vibration energy in the space, and the spraying strength of the aerosol is enhanced. Further, the vertical height of the notch of the groove 110 to the groove bottom 112 of the groove 110 is less than or equal to 0.4 mm. When the vertical height is more than 0.4 mm, the rigidity of the metal sheet 100 is lowered and the fatigue resistance is also greatly lowered.
Optionally, the groove bottom 112 is a circular plane and is provided with flow guiding holes, the diameter range of the flow guiding holes is 1 micron to 4 microns, and the flow guiding holes are uniformly distributed on the groove bottom 112. The flatness of the groove bottom 112 has a great influence on the aerosol performance of the metal sheet 100, the flat groove bottom 112 can enable the liquid medicine to be in full contact with the second surface 102 of the metal sheet 100, and the liquid medicine is in continuous contact with the flow guide holes during vibration of the metal sheet 100, so that intermittent aerosol cannot be formed. Intermittent aerosol is retained in the water conservancy diversion hole, leads to 1 ponding of aerosol generating device easily, shows the atomizer infiltration at last, when atomizing some turbid liquid medicines, leads to 1 stifled hole of aerosol generating device even. Therefore, the groove bottom 112 is flat to prevent the atomizer from water leakage. Alternatively, the diversion holes may be helical. The spiral flow guide hole is used for prolonging the vibration distance of the metal sheet 100 to the aerosol so that the aerosol continuously receives vibration energy; moreover, the aerosol is sprayed out along the spiral shape, the circumferential speed of the aerosol is increased, and the spraying speed of the aerosol is further increased.
The piezoelectric transducer 200 shown in fig. 1 is flat and annular, a first through hole 201 is formed in the middle, the piezoelectric transducer 200 is fixed to the first surface 101 of the metal sheet 100, and the piezoelectric transducer 200 has an effect of converting electric energy into mechanical energy. The piezoelectric transducer 200 of the present embodiment is made of piezoelectric ceramics. The connection mode of the piezoelectric ceramic and the metal sheet 100 can be selected as follows: bake the sheetmetal 100 on piezoceramics or adopt sticky mode to connect, also or through connection modes such as welding, the utility model discloses do not prescribe a limit to this.
Further, the first through holes 201 of the piezoelectric transducer 200 should cover even more than the area of the groove 110 of the metal sheet 100, i.e. the area of the first through holes 201 is larger than the area of the notches of the groove 110. The aerosol is ejected from the first surface 101 to the area of the first through hole 201 without interference. Further, the first through hole 201 is coaxial with the groove 110 of the metal sheet 100, so that the aerosol ejecting direction is not deviated during the vibration of the piezoelectric transducer 200.
As shown in fig. 1, the piezoelectric transducer 200 is provided with a positive terminal 210 on the side facing away from the metal sheet 100. Optionally, two positive terminals 210 are provided to facilitate user installation options. The edge of the metal sheet 100 is provided with a negative terminal lug 120. The central axes of the positive terminal 210 and the negative terminal groove 110 are uniformly distributed at intervals, so as to prevent the electrode bar from short circuit in the use process or in water seepage. It should be understood that the negative terminal lug 120 of the aerosol-generating device 1 may also be disposed on the connecting surface of the piezoelectric transducer 200 and the metal sheet 100, but at the same time, it is also spaced uniformly around the central axis of the first through hole 201.
The piezoelectric transducer 200 is provided with a conducting coating (not shown) on the side away from the metal sheet 100, and the conducting coating is provided with a conducting loop which is in contact with the positive terminal 210. Optionally, the conductive coating material is silver paste.
