Fig. 2 is a schematic view of another ultrasonic atomizing device provided in an embodiment of the present application, unlike the example of fig. 1, the ultrasonic atomizer 10 is detachably connected, such as by a snap or magnetic connection, to a power supply assembly 20.
For ease of illustration, the following examples are described with the ultrasonic atomizer 10 detachably connected to the power supply assembly 20 only.
As shown in fig. 3 to 10, the ultrasonic atomizer 10 includes:
the main body 101 is substantially flat and cylindrical. The body 101 has longitudinally opposed proximal and distal ends; the proximal end is configured to serve as one end for sucking aerosol by a user, and a suction nozzle opening for sucking by the user is arranged at the proximal end; while the distal end is taken as the end to which the power supply assembly 20 is coupled and the distal end of the body 101 is open, with a removable bottom cap 106, such as a snap-fit connection, mounted thereon. After being combined with the bottom cover 106, the main body 101 and the bottom cover 106 together define a housing of the ultrasonic atomizer 10, and the inside thereof is hollow and provided with necessary functional means for storing and atomizing a liquid matrix; through the opening of the main body 101, each necessary functional component can be installed inside the housing of the ultrasonic atomizer 10.
As will be understood in conjunction with fig. 10, the bottom cover 106 is provided with first electrode holes 1061 and second electrode holes 1062, to which the first electrodes 107 and the second electrodes 108 are mounted in one-to-one correspondence. The first electrode 107 and the second electrode 108 preferably employ elastic electrodes, and the ultrasonic atomizer 10 may be electrically connected to the power supply assembly 20 through the first electrode 107 and the second electrode 108. At the same time, an air inlet 1063 is also provided in the bottom cover 106 for the entry of outside air into the ultrasonic atomizer 10 during suction. The bottom cover 106 is further provided with a collecting cavity 1064, and the first electrode hole 1061, the second electrode hole 1062, and the air inlet 1063 are all protruded from the collecting cavity 1064, where the collecting cavity 1064 is used for collecting the leaked liquid matrix, so as to prevent the leaked liquid matrix from flowing to the power component 20. The side wall of the bottom cover 106 has a step 1065, which is described below.
The interior of the housing is provided with a liquid storage chamber a for storing a liquid matrix, an elastic seal 102, an ultrasonic atomizing sheet 103 for ultrasonic atomizing the liquid matrix, a liquid guiding member 104 for sucking the liquid matrix, and a liquid guiding member 105 for sucking the liquid matrix from the liquid storage chamber a and transmitting the liquid matrix to the liquid guiding member 104.
A flue gas transmission pipe 1011 is arranged in the main body 101 along the axial direction, and a liquid storage cavity A for storing liquid matrixes is defined by the space among the outer wall of the flue gas transmission pipe 1011, the inner wall of the main body 101 and the first end part 102a of the elastic sealing piece 102; one end of the fume transmission pipe 1011 is communicated with the suction nozzle, so that generated aerosol is transmitted to the suction nozzle for sucking. In a preferred embodiment, the smoke delivery tube 1011 and the main body 101 are integrally molded from a moldable material, such that the liquid storage chamber A formed after the preparation is open or open toward the distal end.
As will be appreciated in connection with fig. 7-8, the elastomeric seal 102 has a first end 102a and a second end 102b opposite in the longitudinal direction of the body 101. The elastomeric seal 102 is preferably made of a flexible material such as silicone, thermoplastic elastomer.
Adjacent the second end 102b, a receiving chamber 102c for receiving the ultrasonic atomizing plate 103 is also provided in the elastic seal member 102. The liquid guiding element 104 is combined on part of the upper surface of the ultrasonic atomizing sheet 103 and is accommodated in the accommodating cavity 102c together with the ultrasonic atomizing sheet 103; in an alternative implementation, a portion of the liquid guiding element 104 is bonded to a portion of the upper surface of the ultrasonic atomizing sheet 103, and another portion of the liquid guiding element 104 is sandwiched between another portion of the upper surface of the ultrasonic atomizing sheet 103 and the abutment 102 d. An abutting part 102d is arranged in the accommodating cavity 102c, and the upper surface 103a of the part of the ultrasonic atomizing sheet 103 which is not combined with the liquid guide element 104 is kept in contact with the abutting part 102d and elastically abutted; the inner wall of the housing chamber 102c is kept in contact with the peripheral side wall (extending from the upper surface to the lower surface) of the ultrasonic atomizing sheet 103; in this way, a good sealing effect is facilitated between the elastic sealing member 102 and the ultrasonic atomizing sheet 103. The area of the portion of the upper surface 103a not bonded to the liquid guiding member 104 is much smaller than the area of the portion of the upper surface bonded to the liquid guiding member 104, and the portion of the upper surface 103a not bonded to the liquid guiding member 104 is disposed next to the peripheral side wall of the ultrasonic atomizing sheet 103. Because the abutting part 102d is elastically abutted with the ultrasonic atomizing sheet 103, the ultrasonic atomizing sheet 103 can buffer vibration through the elasticity of the ultrasonic atomizing sheet 103 when vibrating at high frequency, so that damage to the ultrasonic atomizing sheet 103 is avoided.
A pair of liquid channels 102e are symmetrically arranged along the transverse direction of the main body 101, the liquid channels 102e penetrate from the first end 102a to the accommodating cavity 102c, the liquid matrix in the liquid storage cavity a is transferred to the liquid guide element 104 through the liquid channels 102e, and is atomized into aerosol under the high-frequency vibration generated by the ultrasonic atomization sheet 103, and the transfer path of the liquid matrix can be shown by referring to R1 in fig. 5. As shown in fig. 8, the port at the lower end (liquid outlet end) of the liquid passage 102e is arranged stepwise with the abutting portion 102 d; the portion of the upper surface 103a not bonded to the liquid guiding member 104 is offset or displaced from the port at the lower end of the liquid passage 102 e; the liquid guide 104 covers the port at the lower end of the liquid channel 102 e.
In an alternative embodiment, a liquid guiding element 105 is disposed in the liquid channel 102e for sucking the liquid matrix from the liquid storage cavity a and transferring the liquid matrix to the liquid guiding element 104; advantageously, by liquid-guiding element 104 drawing liquid matrix from liquid-guiding element 105, excessive or too rapid transfer of liquid matrix to ultrasonic atomizing sheet 103 causing frying oil may be avoided. In alternative embodiments, the liquid guiding element 105 and the liquid guiding element 104 may be integrally formed.
In another alternative embodiment, the liquid guiding element 105 may be arranged between the elastic seal 102 and the liquid storage chamber a; in this way, the liquid guide member 105 draws the liquid matrix from the liquid storage chamber a and transmits it to the liquid guide member 104 through the liquid passage 102 e.
A smoke passage 102g is formed between the pair of liquid passages 102e, i.e., from the first end 102a to the housing chamber 102c. The other end of the flue gas transmission pipe 1011 is inserted into the flue gas channel 102 g; one end of the flue gas channel 102g is kept in contact with the liquid guiding element 104, so that the liquid guiding element 104 is abutted against part of the upper surface of the ultrasonic atomization sheet 103; the inner wall of the flue gas channel 102g and the upper surface of the ultrasonic atomizing sheet 103 define at least part of an atomizing chamber; the airflow guide 102f is symmetrically provided in the thickness direction of the main body 101, and one end of the smoke passage 102g is recessed to form an airflow groove (not shown) communicating with the airflow guide 102 f. In this way, at the time of suction (refer to R2 in fig. 6), after the external air enters the ultrasonic atomizer 10 through the air inlet 1063, the external air flows into the smoke passage 102g along the air flow guide 102f and the air flow groove in a direction-changing manner, flows into the smoke transmission pipe 1011 together with the aerosol formed by ultrasonic atomization, and is sucked by the user. Further, the air flow guide portion 102f is also provided with an air flow guide surface (not shown) inclined with respect to the upper surface of the horizontally arranged liquid guide element 104 or the ultrasonic atomizing sheet 103 so that the redirected air flow can flow into the smoke passage 102g at a preset angle.
The peripheral side wall of the elastic seal 102 abuts against the inner wall of the main body 101, thereby forming a seal. Further, the peripheral side wall of the elastic seal member 102 is provided with a protrusion 102h and a protrusion 102i, the protrusion 102h being provided near the first end 102a, the protrusion 102i being provided near the second end 102 b; in this way, a better sealing effect can be formed by the protruding portion 102h and the protruding portion 102 i.
A step 102j is also provided between the receiving cavity 102c and the second end 102b.
After assembly, the second end 102b abuts against the step 1065 of the bottom cover 106 and is clamped between the peripheral side wall of the bottom cover 106 and the inner wall of the main body 101, the step 102j abutting against the upper end face of the bottom cover 106; in this way, a good seal is facilitated between the resilient seal 102 and the bottom cover 106.
As will be understood from fig. 9, the ultrasonic atomizing plate 103 has a substantially elongated shape, unlike a conventional circular ultrasonic atomizing plate, and has a portion of its upper surface combined with the liquid guiding element 104, and a lower surface formed with a first electrical connection portion 1031 and a second electrical connection portion 1032, the first electrical connection portion 1031 being disposed next to the right end of the ultrasonic atomizing plate 103, and the second electrical connection portion 1032 being disposed next to the left end of the ultrasonic atomizing plate 103. After assembly, one end of the first electrode 107 is exposed on the bottom cover 106, and the other end is kept in contact with the first electrical connection portion 1031 to form an electrical connection; one end of the second electrode 108 is exposed on the bottom cover 106, and the other end is kept in contact with the second electrical connection portion 1032 to form an electrical connection; one end of the electrode exposed on the bottom cover 106 is electrically connected to an electrical contact (not shown) on the power supply assembly 20. The first electrode 107 and the second electrode 108 simultaneously form a support for the lower surface of the ultrasonic atomizing sheet 103 to hold the ultrasonic atomizing sheet 103 in the housing chamber 102c. In a preferred implementation, the projections of the first electrical connection 1031 and the second electrical connection 1032 on the upper surface of the ultrasonic atomizing sheet 103 at least partially overlap with the portion of the upper surface 103a that is not bonded to the liquid guiding element 104; in this way, the ultrasonic atomizing sheet 103 is advantageously held in the housing chamber 102c by the abutment of the abutment portion 102d and the support of the electrode.
It should be noted that, in other examples, the first electrical connection portion 1031 and the second electrical connection portion 1032 are provided on different surfaces, as well. For example: the first electrical connection portion 1031 is provided on the lower surface of the ultrasonic atomizing sheet 103, and the second electrical connection portion 1032 is provided on the upper surface of the ultrasonic atomizing sheet 103; in further implementations, the second electrical connection 1032 may also extend along the peripheral wall to the lower surface to be disposed on the same surface as the first electrical connection 1031.
In other examples, it is also possible to support the ultrasonic atomizing sheet 103 by any one of the first electrode 107 and the second electrode 108.
The liquid guiding element 104 is made of flexible strips or rod-like fibrous material, such as cotton fibers, nonwoven fibers, sponges, etc.
The liquid guiding member 105 is made of an organic porous material having elasticity, and exhibits moderate flexibility and rigidity. In practice, the fluid transfer element 105 has a modulus of elasticity or stiffness that is less than the body 101 or the material defining the fluid storage chamber a, and greater than the material of the fluid transfer element 104. In particular to hard artificial cotton with the Shore hardness of 20-70A. In alternative implementations, the liquid guiding element 105 is a hard rayon comprising oriented polyester fibers, or a hard rayon or rayon made of a filiform polyurethane, or the like.
