The lower case 21 has a cylindrical structure with both ends open. The lower housing 21 and the upper housing 11 define a housing forming the electronic atomizing device 100. The outer surface of the lower case 21 is provided with an air flow inlet through which outside air flows into the lower case 21. A part of the outer surfaces of the front and rear sides of the lower case 21 is protruded so that the size of a part of the power supply assembly 20 in the thickness direction is increased, and thus the induction coil 26 of a larger size can be accommodated.
The lower holder 22 is accommodated in the lower case 21, and the battery cell 23, the circuit 24, the base 25, the induction coil 26, the shield 27, and the sensor 28 are provided on the lower holder 22. The length direction dimension of the lower bracket 22 is smaller than the length direction dimension of the lower housing 21. A receiving cavity B is defined between the upper end of the lower bracket 22 and the upper end of the lower housing 21 or between the lower bracket 22 and the inner surface of the lower housing 21, and the lower end of the lower bracket 22 is abutted with the end part of the lower end of the lower housing 21; after assembly, a portion of the upper housing 11 is received in the receiving cavity B.
The battery 23 provides electrical power for operating the electronic atomizing device 100. The battery 23 may be a rechargeable battery or a disposable battery.
The circuit 24 may control the overall operation of the electronic atomizing device 100. The circuit 24 controls not only the operation of the battery cell 23 and the induction coil 26, but also the operation of other elements in the electronic atomizing device 100. The circuit 24 includes at least one processor. The processor may comprise an array of logic gates, or may comprise a combination of a general purpose microprocessor and a memory storing programs executable in the microprocessor. Furthermore, those skilled in the art will appreciate that the circuitry 24 may include another type of hardware.
At least a portion of the base 25 defines a receiving cavity C. In particular, the base 25 is substantially tubular, the hollow portion of the interior of which defines or forms at least part of the receiving cavity C. The second connecting portion 162 of the base 16 is at least partially received within the receiving cavity C when assembled. When the second connecting portion 162 of the base 16 is received in the receiving cavity C, the first connecting portion 161 is held in contact with the base 25, while the bottom surface of the second connecting portion 162 is held in contact with the bottom wall of the receiving cavity C or the gap is negligible.
The induction coil 26 generates a varying magnetic field under alternating current, and the battery cell 23 supplies a high frequency oscillating current to the induction coil 26. The frequency of the alternating current supplied to the induction coil 26 is between 500KHz and 3MHz; preferably, the frequency can be between 500KHz and 2.5MHz; further preferably, the frequency may be between 500KHz and 2MHz; further preferably, the frequency may be between 500KHz and 1.5MHz; further preferably, the frequency may be between 500KHz and 1MHz.
As shown in fig. 8, the main body portion 26a of the induction coil 26 is configured as a tubular induction coil spirally wound around the central axis S2. The body portion 26a is sleeved or encircling the periphery of the base 25, i.e. circumferentially or circumferentially arranged around the receiving chamber C. The body portion 26a may have an oval, circular, square, rectangular, triangular, or other polygonal cross-section. For example, for a body portion 26a of circular cross-section, the central axis S2 is the line between the center of the circular cross-section at the top end of the body portion 26a and the center of the circular cross-section at the bottom end; other shapes are similar to this. The electric connection portions 26b and 26c of the induction coil 26 are electrically connected to the battery cell 23.
The body portion 26a is wound from a longer wire material, such as: the winding and forming process is carried out by adopting 500-2000 wires, or adopting 500-1900 wires, or adopting 700-1900 wires, or adopting 900-1900 wires, or adopting 1000-1900 wires, or adopting 1200-1900 wires, or adopting 1400-1900 wires, or adopting 1600-1900 wires. The cross-section of the wire material may be rectangular, circular or oval.
The number of turns or windings of the body portion 26a is between 4 turns and 20 turns; preferably, between 6 and 20 turns; further preferably, between 6 and 15 turns; further preferably, between 6 and 12 turns; further preferably between 6 and 10 turns. The spacing between adjacent turns or windings is about 0.1-0.5 mm; in a specific embodiment, the spacing between adjacent turns or windings is 0.2 or 0.4mm.
The axial span d1 of the susceptor 141 along the central axis S1 is generally less than one third (approximately between one quarter and one third) of the axial span of the second connecting portion 162 based on factors such as the design of the susceptor 141 or the overall design of the electronic atomizing device 100. In order to enable the susceptor 141 to be fully inserted into the induction coil 26 when the second connection portion 162 of the base 16 is received in the receiving chamber C, the axial span d11 of the induction coil 26 along the central axis S2 is greater than the axial span d1 of the susceptor 141 along the central axis S1, and the axial span d11 of the induction coil 26 along the central axis S2 is more than two-thirds of the axial span d12 of the receiving chamber C along the central axis S2, which can be the same as d12 at maximum. In this way, the susceptor 141 can be completely embedded within the induction coil 26, and the coupling of the alternating magnetic field generated by the induction coil 26 to the susceptor 141 is significantly increased. Fig. 9 shows the susceptor 141 fully inserted into the induction coil 26. The susceptor 141 is fully inserted into the induction coil 26, meaning that both the upper and lower ends of the susceptor 141 are spaced apart from the upper and lower ends of the induction coil 26 correspondingly.
In one example, the axial span d11 of the induction coil 26 along the central axis S2 may be more than twice the axial span d1 of the susceptor 141 along the central axis S1. Preferably between 2 and 3 times.
In one example, the axial span d11 of the induction coil 26 along the central axis S2 is between 10mm and 15mm; preferably, the diameter is between 10mm and 14mm; further preferably, the diameter is between 10mm and 13mm; more preferably, the diameter is 11mm to 13mm.
In further implementations, the offset distance between the central axis S1 of the susceptor 141 and the central axis S2 of the induction coil 26 is between 0 and 3mm (inclusive). The susceptor 141 is offset from the midpoint K1 of the axial span of the central axis S1 by an offset distance (including the end point values) of 0-3 mm from the midpoint K2 of the axial span of the induction coil 26 along the central axis S2. When the offset distance between the central axis S1 of the susceptor 141 and the central axis S2 of the induction coil 26 is 0mm, this means that the central axis S1 coincides with the central axis S2; when the distance between the midpoint K1 of the axial span of the susceptor 141 along the central axis S1 and the midpoint K2 of the axial span of the induction coil 26 along the central axis S2 is 0mm, this means that the center of the susceptor 141 coincides with the center of the induction coil 26 or the center in the axial direction. Fig. 10-11 show the situation where these 2 are all coincident.
This is advantageous in that the alternating magnetic field generated by the induction coil 26 is strongest at its center and weaker at its two ends; therefore, the center axis S1 coincides with the center axis S2 and the center of the susceptor 141 coincides with the center of the induction coil 26, meaning that the coupling of the alternating magnetic field generated by the induction coil 26 to the susceptor 141 is optimized and the conversion efficiency of the induction heating assembly constituted by the induction coil 26 and the susceptor 141 is optimized.
The inventors tested the distance between the central axis S1 and the central axis S2 (corresponding to D2 in the following table), the distance between the midpoint K1 of the axial span of the susceptor 141 along the central axis S1 and the midpoint K2 of the axial span of the induction coil 26 along the central axis S2 (corresponding to D1 in the following table), and the test results were as follows:
| sequence number | D1 | D2 | Conversion efficiency |
| 1 | 0 | 0 | 85.34％ |
| 2 | 1mm | 0 | 74.58％ |
| 3 | 2mm | 0 | 63.26％ |
| 4 | 3mm | 0 | 51.24％ |
| 5 | 0 | 1mm | 72.56％ |
| 6 | 0 | 2mm | 59.76％ |
| 7 | 0 | 3mm | 46.59％ |
The above test results can indicate that: the central axis S1 coincides with the central axis S2, and the center of the susceptor 141 coincides with the center of the induction coil 26, so that the conversion efficiency of the induction heating assembly is optimal, about 85.34%; when the distance between the central axis S1 and the central axis S2 increases, or the distance between the midpoint K1 of the axial span of the susceptor 141 along the central axis S1 and the midpoint K2 of the axial span of the induction coil 26 along the central axis S2 increases, the conversion efficiency of the induction heating assembly tends to decrease; the change in distance between the central axis S1 and the central axis S2 has a greater influence on the conversion efficiency of the induction heating assembly than the change in distance between the central point K1 of the axial span of the susceptor 141 along the central axis S1 and the central point K2 of the axial span of the induction coil 26 along the central axis S2.
Referring again to fig. 4-5 and 7, similar to the foregoing, the distance between the midpoint K1 of the axial span of the susceptor 141 along the central axis S1 and the bottom end surface of the second connecting portion 162 is d2, the distance between the midpoint K2 of the axial span of the induction coil 26 along the central axis S2 and the bottom wall of the receiving chamber C is d13, and the difference between d2 and d13 is 0-3 mm. The distance between the central axis S1 and the outer surface of the second connecting portion 162 is d3, the distance between the central axis S2 and the inner wall of the receiving chamber C is d14, and the difference between d3 and d14 is 0 to 3mm.
In a further implementation, the minimum radial distance d15 between the induction coil 26 and the susceptor 141 is between 3 and 7mm; preferably, the diameter is 3-6 mm; further preferably, the diameter is 4 to 6mm. The coupling of the alternating magnetic field generated by the induction coil 26 to the susceptor 141 is ensured.
The shield 27 is disposed around or sleeved outside the induction coil 26. The shield 27 serves to shield the magnetic field emanating from the induction coil 26 in a generally radial direction to avoid that emanating magnetic field affects other components.
The sensor 28 senses a change in the air flow in the lower housing 21 by sensing the passage, i.e. detects the user's suction, to generate a signal to control the start of operation of the nebuliser 10.
