Description

Technical Field

[0001] This utility model relates to atomizing devices, specifically to a wireless atomizer. Background Technology

[0002] Nebulizers have wide applications in humidifiers, fragrances, and pharmaceuticals. Traditional nebulizers are wired and integrated, combining the atomizer, power supply, and liquid container into one unit. This often presents the problem of inconvenience when adding water or fragrances. To address this issue, those skilled in the art developed wireless nebulizers, where the atomizing nozzle and wireless power supply module are separate. The wireless power supply module transmits power to the atomizing nozzle wirelessly. Because the atomizing nozzle is a wireless, separate module, adding water or fragrances to the liquid container on the nozzle is convenient. However, after application, this wireless nebulizer was found to have excessive power consumption, especially when the atomizing nozzle is removed from the wireless charging module to add the solution. In this case, the atomizing nozzle's spray function is not activated, and the continuous power transmission from the wireless power supply module to the atomizing nozzle becomes ineffective energy loss. Utility Model Content

[0014] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0015] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0016] See Figure 1-4 As shown in the preferred embodiment of this utility model, a wireless atomizer is provided, including a wireless power supply module 1 and a spray module 2. The wireless power supply module 1 and the spray module 2 are two separable independent modules. The wireless power supply module 1 can wirelessly supply power to the spray module 2. Specifically, the wireless power supply module 1 includes a first housing, a power cord 12, a wireless power transmitting coil 13 installed in the first housing, and a first control circuit board 14. The first housing is composed of an upper cover 110 and a lower cover 120. The first control circuit board 14 further includes a power conversion circuit, a signal generation circuit, a coil driving circuit, and a control circuit. The coil driving circuit is used to controllably drive the wireless power transmitting coil 13 to supply power to the spray module. The spray module 2 includes a second housing with a spray nozzle 21 formed thereon. An atomizing plate 22 is fixedly disposed at the spray nozzle 21. A second control circuit board 23 and a wireless power receiving coil 24 are fixedly disposed inside the second housing. The second housing consists of a front cover 210, a rear cover 220, and a nozzle cover 230. A storage chamber for atomized liquid is also provided inside the second housing. Electrical energy is transmitted to the wireless power receiving coil 24 via the wireless power transmitting coil 13. The second control circuit board 23 controls the activation of the atomizing plate 22, causing the atomized liquid to be sprayed from the spray nozzle 21 after being atomized by the atomizing plate 22. Silicone rings are provided on the atomizing plate 22 and the spray nozzle 21 to prevent atomized water from leaking out of the spray nozzle 21. The atomization function of the atomizing plate 22 and the wireless power supply function of the wireless power supply module 1 to the spray module 2 are achievable by those skilled in the art using existing technology; therefore, the underlying principles will not be further elaborated in this example.

[0017] See Figure 3 and Figure 4In this embodiment, a first proximity sensor 3 and a second proximity sensor 4 are fixedly mounted on the wireless power supply module 1 and the spray module 2, respectively. The first proximity sensor 3 can sense the approach or departure of the second proximity sensor 4. For example, the first proximity sensor 3 can be a Hall sensor and the second proximity sensor 4 can be a magnet; or, the first proximity sensor 3 can be an inductive sensor and the second proximity sensor 4 can be a metal part; or, the first proximity sensor 3 and the second proximity sensor 4 can be through-beam photoelectric sensors. Any proximity sensor capable of displacement detection is a feasible solution. However, to prevent false alarms and improve sensing accuracy, it is preferable that the first proximity sensor 3 and the second proximity sensor 4 use a Hall sensor and a magnet.

[0018] The first proximity sensor 3 and the first control circuit board 14 are connected by a signal. The first control circuit board 14 can control the coil drive circuit to turn on and off based on whether the first proximity sensor 3 receives a sensing signal from the second proximity sensor 4. That is, when the wireless power supply module 1 and the spray module 2 are close together, the first proximity sensor 3 detects the second proximity sensor 4 and generates a signal. At this time, the first control circuit board 14 controls the coil drive circuit to turn on the power supply from the wireless power supply module 1 to the spray module 2. When the wireless power supply module 1 and the spray module 2 are far apart, the sensing signals from the first proximity sensor 3 and the second proximity sensor 4 are interrupted, and the first control circuit board 14 controls the coil drive circuit to turn off the power supply from the wireless power supply module 1 to the spray module 2. Therefore, the wireless atomizer of this application can actively enter a low-power mode when the spray module 2 is removed to replace the atomizing liquid and is relatively far away from the wireless power supply module 1, reducing the overall power consumption to below 1mA and saving power consumption during non-atomizing operation.

[0019] To save installation space and improve the overall compactness of the device, both the wireless power transmitting coil 13 and the wireless power receiving coil 24 are flat structures. The wireless power transmitting coil 13 is attached to the first control circuit board 14, and the wireless power receiving coil 24 is attached to the second control circuit board 23.

[0020] See Figure 1 and Figure 2A first connecting portion 100 and a second connecting portion 200 are respectively provided on the first housing and the second housing. The first connecting portion 100 and the second connecting portion 200 are configured to be detachably connected and engaged. In this embodiment, the first connecting portion 100 and the second connecting portion 200 are respectively a locking post and a buckle. The wireless power supply module 1 and the spray module 2 can be temporarily integrated into one unit through the connection of the first connecting portion 100 and the second connecting portion 200, which is convenient for transportation, carrying and packaging. The detachable design of the first connecting portion 100 and the second connecting portion 200 also allows the wireless power supply module 1 and the spray module 2 to be quickly separated. Furthermore, a foolproof positioning groove 300 and a foolproof positioning post 400 are respectively provided on the first housing and the second housing. The quick positioning when the wireless power supply module 1 and the spray module 2 are connected is achieved by inserting the foolproof positioning groove 300 and the foolproof positioning post 400.

[0021] In this embodiment, the first housing has a sheet-like structure, including a first sheet-like plane 101. The second housing includes a second sheet-like plane 201 adapted to the first sheet-like plane 101. The first connecting part 100 and the second connecting part 200 are respectively fixedly disposed on the first sheet-like plane 101 and the first sheet-like plane 102. The spray nozzle 21 and the second sheet-like plane 201 are respectively disposed on opposite sides of the second housing. Thus, when the wireless power supply module 1 and the spray module 2 are temporarily connected as one unit, the overall appearance of the wireless atomizer is more integrated, the structure is compact, and it occupies less space. Furthermore, the spray nozzle 21 can still normally spray atomized liquid without hindering the normal use of the atomizer.
