Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to an elastic conductive element, an atomization assembly and its assembly method, an ultrasonic atomizer, and an ultrasonic atomization device. Background Technology

[0002] An ultrasonic atomizer includes an ultrasonic atomizing plate with micropores. When the ultrasonic atomizing plate vibrates at high frequency, it can atomize the liquid matrix in the micropores into a liquid mist, which is then sprayed out from the micropores for the user to inhale.

[0003] A resistor plate is connected between the upper and lower surface electrodes of the existing ultrasonic atomizing plate. After the ultrasonic atomizer is powered off, the ultrasonic atomizing plate and the resistor on the resistor plate form a closed circuit. This allows the ultrasonic atomizing plate to dissipate the energy stored in it after power is turned on and off, preventing the release of instantaneous high voltage when the ultrasonic atomizing plate is powered on again, which could burn out other electronic components. This ensures that the ultrasonic atomizing plate can work normally after power is turned on again.

[0004] The presence of the resistance plate results in more parts, more processes, and higher costs for the ultrasonic atomizer. Furthermore, the resistance plate is fixed and conductive to the upper and lower surface electrodes of the ultrasonic atomizing plate by screws or solder, which can easily lead to problems such as poor soldering and unreliable fixation. Summary of the Invention

[0035] Figure 1 This is a schematic diagram of the ultrasonic atomizing device provided in the embodiments of this application.

[0036] like Figure 1 As shown, the ultrasonic atomizing device 100 includes an ultrasonic atomizer 10 and a power supply assembly 20, and the ultrasonic atomizer 10 and the power supply assembly 20 are not detachable.

[0037] The ultrasonic atomizer 10 includes a liquid storage chamber (not shown in the figure) for storing a liquid matrix and an atomizing component 11. Under the power provided by the power supply component 20, the atomizing component 11 generates high-frequency oscillation, which atomizes the liquid matrix into liquid mist.

[0038] The power supply assembly 20 includes a battery cell 21 and a circuit 22.

[0039] Battery cell 21 provides power for operating the ultrasonic atomizing device 100. Battery cell 21 can be a rechargeable battery cell or a disposable battery cell.

[0040] Circuit 22 can control the overall operation of the ultrasonic atomizing device 100. Circuit 22 not only controls the operation of the battery cell 21 and the atomizing assembly 11, but also controls the operation of other components in the ultrasonic atomizing device 100.

[0041] Figure 2 This is a schematic diagram of another ultrasonic atomizing device provided in the embodiments of this application, and... Figure 1 The difference is that the ultrasonic nebulizer 10 is detachably connected to the power supply assembly 20.

[0042] like Figures 3-5 As shown, this application provides an atomizing component 11, including an ultrasonic atomizing sheet 111, a first electrical connector (112, 115), an elastic conductive element 113, and a second electrical connector 114.

[0043] In this example, the ultrasonic atomizing sheet 111 includes a piezoelectric ceramic substrate, which is generally circular, with a first electrode 111a formed on its upper surface and a second electrode 111b formed on its lower surface.

[0044] The first electrical connector (112, 115) includes a conductive sleeve 112 and a coupling member 115. The ultrasonic atomizing plate 111, the elastic conductive element 113, and the second electrical connector 114 are all disposed within the conductive sleeve 112. Specifically, the ultrasonic atomizing plate 111 is horizontally positioned near the upper end (first end) of the conductive sleeve 112, and the elastic conductive element 113 and the second electrical connector 114 are disposed between the ultrasonic atomizing plate 111 and the lower end (second end) of the conductive sleeve 112. The conductive sleeve 112 is separated from the second electrical connector 114 by the elastic conductive element 113.

[0045] One region of the elastic conductive element 113 is directly or indirectly electrically connected to the first electrode 111a of the ultrasonic atomizing plate 111, and another region of the elastic conductive element 113 is directly or indirectly electrically connected to the second electrode 111b, so that a circuit is formed between the first electrode 111a, the elastic conductive element 113, and the second electrode 111b. It should be noted that one region and the other region of the elastic conductive element 113 can be any two regions or parts of the elastic conductive element 113, as long as direct contact between the first electrode 111a and the second electrode 111b is avoided to prevent a short circuit.

[0046] In the preferred implementation, such as Figure 5 , Figure 8 As shown, the elastic conductive element 113 is constructed as a cylindrical structure, comprising a cylindrical body. The upper end 113a (proximal end) of the cylindrical body has multiple annular protrusions 113b arranged radially. The lower end 113d (distal end) of the cylindrical body has a downwardly extending portion to form a boss 113e. The hollow portion of the cylindrical body forms a receiving chamber 113c, which extends from the upper end 113a to the lower end 113d. The shape of the receiving chamber 113c matches the shape of the second electrical connector 114 for accommodating and securing the second electrical connector 114. The protrusions 113b abut against the lower surface of the ultrasonic atomizing plate 111 to support the ultrasonic atomizing plate 111. At least partially, the sidewall of the elastic conductive element 113 abuts against the inner wall of the conductive sleeve 112 to form an electrical connection.

[0047] The elastic conductive element 113 is molded from a mixture of elastic material and metal particles. The elastic material can be silicone, soft rubber, etc. Thus, the elastic conductive element 113 itself has a certain resistance, which is greater than 500KΩ; or greater than 800KΩ; or greater than 1MΩ; or greater than 1MΩ and less than 2MΩ. The elastic conductive element 113, on the one hand, reduces the vibration transmission of the ultrasonic atomizing plate 111 through its own elasticity; on the other hand, it maintains contact with both the first electrical connector and the second electrical connector 114 to form an electrical connection, thereby forming a circuit to consume the energy stored in the ultrasonic atomizing plate 111 after being energized and de-energized. This ensures that the ultrasonic atomizing plate 111 can work normally after being energized again, preventing the release of instantaneous high voltage upon re-energization and thus avoiding damage to other electronic components. Because the elastic conductive element 113 itself has a relatively high resistance, while the ultrasonic atomizing plate 111 has a relatively low resistance, the energy consumed by the elastic conductive element 113 is very small when the ultrasonic atomizing plate 111 is working. Understandably, the elastic conductive element 113 also has a sealing effect. Because it is in contact with the lower surface of the ultrasonic atomizing plate 111 and the inner wall of the conductive sleeve 112, it can prevent the liquid matrix from leaking or flowing towards the lower end 113d in the cylindrical body.

[0048] In this example, since the elastic conductive element 113 is used instead of a separate resistor plate, the distance d1 between the upper and lower ends of the conductive sleeve 112 is much smaller than that of the existing scheme. Generally, d1 is between 5mm and 6mm; or between 5.2mm and 6mm; or between 5.4mm and 6mm; or between 5.5mm and 6mm.

[0049] The lower surface of the ultrasonic atomizing plate 111 faces the second electrical connector 114, such that one end of the second electrical connector 114 abuts against the second electrode 111b formed on the lower surface of the ultrasonic atomizing plate 111 to maintain contact and thus form an electrical connection, and the other end of the second electrical connector 114 extends toward the lower end of the conductive sleeve 112. The upper end of the conductive sleeve 112 has a radially extending extension (not shown in the figure), which abuts against the first electrode 111a formed on the upper surface of the ultrasonic atomizing plate 111 to maintain contact and thus form an electrical connection.

[0050] It should be noted that the first electrode 111a and the second electrode 111b on the ultrasonic atomizing plate 111 are not limited to the situation shown in the figure. In other examples, the first electrode 111a and the second electrode 111b can be respectively disposed on both sides of the ultrasonic atomizing plate 111, or on one side, or disposed on the same surface of the ultrasonic atomizing plate 111 (for example, both disposed on the lower surface of the ultrasonic atomizing plate 111). As the positions of the first electrode 111a and the second electrode 111b change, the structures of the elastic conductive element 113, the first electrical connector (112, 115), and the second electrical connector 114 can also change accordingly; for example, the elastic conductive element 113 can be electrically connected to the first electrode 111a and the second electrode 111b on one side of the ultrasonic atomizing plate 111; the elastic conductive element 113 can also be disposed in a manner that wraps around the ultrasonic atomizing plate 111, electrically connected to the first electrode 111a on one side and electrically connected to the second electrode 111b on the other side.

[0051] The coupling element 115 is disposed near the lower end of the conductive sleeve 112 and held on the boss 113e. The coupling element 115 is ring-shaped and can be sleeved on the boss 113e. The coupling element 115 and the conductive sleeve 112 are kept in contact to form an electrical connection. In this way, when the atomizing assembly 11 is coupled to the battery cell 21, the lead wire can be advantageously soldered to the other end of the coupling element 115 and the second electrical connector 114.

[0052] exist Figures 3-8 In the example, the first electrical connector (112, 115) includes a conductive sleeve 112 and a coupling member 115, meaning the first electrical connector is formed by two or more separate components. Figures 3-8 Unlike the example, in other examples, it is also possible for the first electrical connection to be implemented by a single or integrally formed structural component.

[0053] exist Figures 3-8 In the example, the elastic conductive element 113 maintains contact with the first electrical connector to form an electrical connection, and the elastic conductive element 113 also maintains contact with the second electrical connector 114 to form an electrical connection. That is, it is indirectly electrically connected to the first electrode 111a through the first electrical connector and indirectly electrically connected to the second electrode 111b through the second electrical connector 114. Figures 3-8The difference lies in the example itself. In other examples, it is also feasible for the elastic conductive element 113 not to maintain contact with the first electrical connector, nor with the second electrical connector 114. Specifically, it is feasible for the elastic conductive element 113 to directly maintain contact with the first electrode 111a to form an electrical connection, and for the elastic conductive element 113 to directly maintain contact with the second electrode 111b to form an electrical connection. Furthermore, it is also feasible for the elastic conductive element 113 to maintain contact with both the first electrode 111a and the first electrical connector to form an electrical connection, and for the elastic conductive element 113 to maintain contact with both the second electrode 111b and the second electrical connector 114 to form an electrical connection.

[0054] exist Figures 3-8 In the example, the atomizing assembly 11, consisting of an ultrasonic atomizing plate 111, first electrical connectors (112, 115), an elastic conductive element 113, and a second electrical connector 114, is disposed within the ultrasonic atomizer 10 (and may be detachable from or non-detachable from the power supply assembly 20). Figures 3-8 Unlike the example, in other examples, the atomizing assembly 11, consisting of the ultrasonic atomizing plate 111 and the elastic conductive element 113, can be disposed in the ultrasonic atomizer 10 (detachable or non-detachable from the power supply assembly 20); and it is also feasible to dispose of the first electrical connector (112, 115) and the second electrical connector 114 in the power supply assembly 20; in this case, the first electrical connector (112, 115) and the second electrical connector 114 can be electrically connected to the electrodes in the ultrasonic atomizing plate directly or indirectly.

[0055] Another embodiment of this application also provides a method for assembling an atomizing component, the assembly method comprising:

[0056] Step S11: Provide a conductive sleeve, the first end of which has a first extension extending radially toward its center;

[0057] Step S12: Install the ultrasonic atomizing sheet inside the conductive sleeve, and the first electrode of the ultrasonic atomizing sheet abuts against the first extension.

[0058] Step S13: Install the second electrical connector and the elastic conductive element inside the conductive sleeve, with the second electrical connector abutting against the second electrode of the ultrasonic atomizing sheet and the elastic conductive element abutting against the ultrasonic atomizing sheet.

[0059] In this step, the second electrical connector can be installed inside the conductive sleeve first, and then the elastic conductive element can be installed inside the conductive sleeve; or, the assembled second electrical connector and the elastic conductive element can be installed together inside the conductive sleeve.

[0060] In one example, after installing the second electrical connector and the resilient conductive element within the conductive sleeve, the process further includes:

[0061] The coupling element is installed inside the conductive sleeve, and the coupling element abuts against the inner wall of the conductive sleeve and the elastic conductive element respectively.

[0062] In one example, after installing the second electrical connector and the resilient conductive element within the conductive sleeve, the process further includes:

[0063] The second end of the conductive sleeve is bent to form a second extension that extends radially toward its center.

[0064] In this example, the second extension formed after the second end of the conductive sleeve is bent, and... Figures 3-8 The coupling 115 in the example has a similar function.

[0065] Another embodiment of this application also provides a method for assembling an atomizing component, the assembly method comprising:

[0066] Step S21: Provide a conductive sleeve, the second end of which has a second extension that extends radially toward its center;

[0067] In this step, the second extension of the second end, and Figures 3-8 The coupling 115 in the example has a similar function.

[0068] Step S22: Install the second electrical connector and the elastic conductive element inside the conductive sleeve, with the elastic conductive element abutting against the second extension, and the elastic conductive element separating the conduit sleeve from the second electrical connector;

[0069] In this step, the second electrical connector can be installed inside the conductive sleeve first, and then the elastic conductive element can be installed inside the conductive sleeve; or, the assembled second electrical connector and the elastic conductive element can be installed together inside the conductive sleeve.

[0070] Step S23: Install the ultrasonic atomizing sheet inside the conductive sleeve, and the first electrode of the ultrasonic atomizing sheet abuts against the second electrical connector;
