Description

Technical Field

[0001] This application relates to the field of atomization technology, and more particularly to an atomizer. Background Technology

[0002] Nebulizers, as a common spray device, are widely used in medical, home, and personal care fields for the nebulization and inhalation of liquid medications or for environmental humidification. Traditional nebulizers typically consist of a main unit, a nebulizing module, and a liquid reservoir. They use the high-frequency vibration of an atomizing plate to convert liquid into tiny particles and spray them out.

[0003] However, existing atomizers, especially in humid environments, leave their nozzles exposed to air for extended periods, making them susceptible to the growth of bacteria, mold, and other microorganisms, potentially posing a health threat to users. Most atomizers only provide atomization functionality and lack active sterilization or self-cleaning capabilities, requiring frequent manual cleaning by users, which is inconvenient. Furthermore, some atomizers with sterilization functions use independent control modules, resulting in a bulky overall structure, higher cost, and potentially affecting atomization performance.

[0015] In some embodiments, the housing assembly further has a mounting hole, which is located within the limiting groove and through which the elastic conductive element is inserted, and the fixed end of the elastic conductive element is connected to the PCB board.

[0016] When the switch assembly slides to the closed position, the free end of the elastic conductive element moves along the opening groove and abuts against the trigger electrode; when the switch assembly slides to the open position, the free end separates from the trigger electrode.

[0017] In some embodiments, the trigger electrode is a metal spring sheet with an arched protrusion on the side facing the elastic conductive element, and the arched protrusion forms a partial contact and conduction with the free end of the elastic conductive element.

[0018] In some embodiments, the atomizing module further includes:

[0019] The atomizing housing has an atomizing chamber and a nozzle communicating with the atomizing chamber, and the power electrode is provided at the bottom of the atomizing housing;

[0020] An atomizing support is disposed within the atomizing chamber, and the atomizing support has a liquid inlet channel;

[0021] A cover plate assembly is disposed on the atomizing bracket; the cover plate assembly has a through-flow channel, the inlet of which is set corresponding to the atomizing plate, and the outlet of which is connected to the nozzle.

[0022] In some embodiments, the atomizing plate is disposed between the atomizing bracket and the cover plate assembly via a sealing gasket.

[0023] In some embodiments, the liquid inlet channel includes a first connecting portion and a second connecting portion integrally connected; the first connecting portion and the second connecting portion are arranged at an angle, the liquid inlet of the first connecting portion opposite to the second connecting portion is connected to the liquid storage tank; the liquid outlet of the second connecting portion opposite to the first connecting portion is arranged corresponding to the atomizing plate.

[0025] In some embodiments, a battery assembly is provided on the side of the receiving cavity near the PCB board. The battery assembly is electrically connected to the PCB board to supply power to the PCB board, the atomizing sheet of the atomizing module, and the disinfection lamp of the sterilization assembly.

[0026] The beneficial effects of this application are as follows: The atomizer includes a main unit assembly, an atomizing module, a liquid storage tank, a switch assembly, and a sterilization assembly; the main unit assembly has a receiving cavity and a nozzle communicating with the receiving cavity, and the outer wall of the main unit assembly is provided with a sliding groove along the axial direction; a PCB board is provided inside the main unit assembly; the atomizing module is disposed in the receiving cavity; the atomizing module includes an atomizing plate and a power electrode; the atomizing plate is disposed corresponding to the nozzle and forms an atomizing channel; the atomizing plate is electrically connected to the power electrode, and the power electrode is electrically connected to the PCB board; the liquid storage tank is detachably connected to the atomizing module and abuts against the main unit assembly; the switch assembly has an open position and a closed position and is slidably disposed in the sliding groove to open or close the nozzle; the sterilization assembly is disposed inside the switch assembly; the sterilization assembly includes a sterilization lamp, an elastic conductive element, and a trigger electrode; when the switch assembly slides to the closed position, the sterilization lamp is disposed opposite to the nozzle, the trigger electrode is connected to the PCB board through the elastic conductive element, and the sterilization lamp is turned on.

[0027] The power electrode is connected to the PCB board of the main unit to supply power to the atomizing plate, causing it to vibrate at high frequency and atomize the liquid in the storage tank into an aerosol. The atomizing module is detachably connected to the storage tank, which abuts against the main unit to ensure a stable supply of liquid to the atomizing plate. The atomizing module is installed in the receiving cavity of the main unit, with its atomizing plate facing the nozzle to ensure that the atomized liquid can be sprayed out smoothly. Furthermore, when the user slides the switch assembly to the open position, the atomization mode is activated, exposing the nozzle and enabling the atomizing plate to operate, resulting in the normal spraying of atomized liquid. When the switch assembly is slid to the closed position, the sterilization mode is activated, with its structure covering the nozzle to prevent external contamination from entering, while simultaneously triggering the sterilization function. At this time, the sterilization lamp inside automatically aligns with the nozzle, irradiating and sterilizing the flow channel and nozzle. The elastic conductive component deforms under pressure when the switch assembly slides, ensuring stable contact with the trigger electrode. Specifically, after the trigger electrode connects to the PCB board, a sterilization circuit is formed, the sterilization lamp starts working, and automatically cuts off the power after a certain period, stopping the sterilization lamp. Alternatively, when the switch assembly leaves the closed position, the elastic conductive component rebounds, the circuit breaks, and the sterilization lamp stops, preventing accidental activation or wasted power. The sterilization lamp, which slides with the switch assembly, is convenient to use. In other words, after the atomizer is turned off, the sterilization lamp automatically applies a sterilization lamp to the nozzle for effective sterilization, ensuring that the nozzle is sterilized and bacteria-free after each use, thereby improving user experience and hygiene safety, while maintaining a compact structure and easy operation.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0039] like Figures 1 to 6 As shown, this application provides an atomizer, including a main unit assembly 2, an atomizing module 4, a liquid storage tank 1, a switch assembly 3, and a sterilization assembly 6; the main unit assembly 2 has a receiving cavity and a nozzle 212 communicating with the receiving cavity, and the outer wall of the main unit assembly 2 is provided with a sliding groove 211 along the axial direction; a PCB board 8 is provided inside the main unit assembly 2; the atomizing module 4 is disposed in the receiving cavity; the atomizing module 4 includes an atomizing plate 7 and a power electrode 44; the atomizing plate 7 is disposed corresponding to the nozzle 212 and forms an atomizing channel; the atomizing plate 7 is electrically connected to the power electrode 44, and the power electrode 44 is connected to the PCB board 8; the liquid storage tank 1 is detachably connected to the atomizing module 4 and abuts against the main unit assembly 2;

[0040] The switch assembly 3 has an open position and a closed position, and is slidably disposed within the slide groove 211 to open or close the nozzle 212; wherein, as Figure 5 and Figure 6 As shown, when the switch assembly 3 slides to the open position, the switch assembly 3 is misaligned with the nozzle 212 to open the nozzle 212; Figures 1 to 3 As shown, when the switch assembly 3 slides to the closed position, the switch assembly 3 covers the nozzle 212 to close the nozzle 212; the sterilization assembly 6 is disposed inside the switch assembly 3; the sterilization assembly 6 includes a sterilization lamp 64, an elastic conductive element 62, and a trigger electrode 63; when the switch assembly 3 slides to the closed position, the sterilization lamp 64 is disposed opposite to the nozzle 212, the trigger electrode 63 is connected to the PCB board 8 through the elastic conductive element 62, the sterilization lamp 64 is turned on, that is, the sterilization lamp 64 is automatically turned off after working for a predetermined time.

[0041] The power electrode 44 is electrically connected to the PCB board 8 of the main unit 2. Preferably, the power electrode 44 includes an elastic electrode needle, one end of which is electrically connected to the electrode of the atomizing plate 7, and the other end is electrically connected to the PCB board 8. The power electrode 4 supplies power to the atomizing plate 7, causing it to vibrate at high frequency and atomize the liquid in the liquid storage tank 1 into an aerosol. The atomizing module 4 is detachably connected to the liquid storage tank 1, and the liquid storage tank 1 abuts against the main unit 2 to ensure that the liquid can be stably supplied to the atomizing plate 7. The atomizing module 4 is installed in the receiving cavity of the main unit 2, and its atomizing plate 7 is directly facing the nozzle 212 to ensure that the atomized liquid can be smoothly sprayed out.

[0042] Specifically, such as Figure 5 and Figure 6 As shown, when the user slides the switch assembly 3 to the open position, the atomization mode is activated, the nozzle 212 is exposed, the atomizing plate 7 works, and the atomized liquid is sprayed out normally; when the user slides the switch assembly 3 to the closed position, the sterilization mode is activated, its structure covers the nozzle 212 to prevent external contamination from entering, and the sterilization function is triggered at the same time; at this time, the sterilization lamp 64 inside automatically aligns with the nozzle 212 to irradiate and sterilize the flow channel 431 and the nozzle 212; wherein, the elastic conductive element 62 is deformed by pressure when the switch assembly 3 slides, ensuring stable contact with the trigger electrode 63; specifically: after the trigger electrode 63 is connected to the PCB board 8, a sterilization circuit is formed, the sterilization lamp 64 starts to work, and automatically cuts off the power after a certain period of time, and the sterilization lamp 64 stops; or as Figures 1 to 3 As shown, when the switch assembly 3 leaves the closed position, the elastic conductive element 62 rebounds, the circuit is broken, and the disinfection lamp 64 stops, avoiding accidental touch or wasting power. The disinfection lamp 64, which slides with the switch assembly 3, is convenient to use.

[0043] The sterilization component 6 is integrated inside the switch component 3. Utilizing the triggering mechanism of the sliding switch component 3, where the trigger electrode 63 is connected to the PCB board 8 via the elastic conductive element 62, no separate control module is needed. Combined with the mechanical structure of the sliding groove 211, this achieves linked atomization and sterilization functions. When turned on, the atomization mode is activated; when turned off, it automatically switches to sterilization mode, making operation simple and requiring no additional user steps. In other words, after the atomizer is turned off, the disinfection lamp 64 automatically applies disinfection light 64 to the nozzle 212 to effectively sterilize it, ensuring that the nozzle 212 is sterilized and bacteria-free after each use. This improves user experience and hygiene safety while maintaining a compact structure and easy operation.

[0044] It is understood that by storing the liquid to be atomized in the storage tank 1, only the storage tank 1 and the atomizing module 4 need to be assembled. Compared with open-type liquid filling, this reduces bacterial growth and improves safety. Furthermore, by making the storage tank 1 and the atomizing module 4 detachably connected, the liquid in the storage tank 1 can be prevented from prolonged contact with the atomizing module 4, thus avoiding the growth of microorganisms and further enhancing safety. Moreover, when the storage tank 1 needs to be replaced, the atomizing module 4 does not need to be replaced simultaneously, which improves the utilization rate of the atomizing module 4 and reduces costs.

[0045] In this embodiment, the main unit 2 further includes a housing assembly 21 and a support assembly 22; the housing assembly 21 has the receiving cavity and the sliding groove 211; wherein, the nozzle 212 passes through the housing assembly 21 and is located within the sliding groove 211; the support assembly 22 is disposed within the receiving cavity; the support assembly 22 includes a partition plate 221, which divides the receiving cavity into a first mounting groove and a second mounting groove distributed vertically; the first mounting groove accommodates the atomizing module 4, and the bottom wall of the first mounting groove is provided with a positioning boss for positioning the atomizing module 4; the second mounting groove accommodates the PCB board 8; the partition plate 221 is provided with a through hole for the power electrode 44 to pass through.

[0046] Furthermore, the housing assembly 21 has a receiving cavity for installing the atomizing module 4, the bracket assembly 22, and some circuit structures. The bracket assembly 22 divides the receiving cavity into two parts by a partition plate 221: a first mounting slot at the top for fixing the atomizing module 4, and a second mounting slot at the bottom for accommodating the PCB board 8, which supplies power to the atomizing module 4 and the sterilization component 6. The power electrode 44 of the atomizing module 4 passes through the through hole of the partition plate 221 and connects to the PCB board 8 in the second mounting slot to ensure stable power supply. The nozzle 212 passes through the housing assembly 21 and is located within the slide groove 211 to ensure that the atomized liquid can be sprayed out smoothly. When the switch assembly 3 slides to the closed position, the nozzle 212 is covered to prevent external contamination from entering, while the sterilization lamp 64 is aimed at the nozzle 212 for sterilization. Thus, by sliding the switch assembly 3 up and down in the slide groove 211, it can switch between the open position (i.e., atomizing mode) and the closed position (i.e., sterilization mode).

[0047] Understandably, after the liquid storage tank 1 is installed, the liquid flows into the atomizing module 4; when the user slides the switch assembly 3 to the open position, the power electrode 44 is energized, and the atomizing plate 7 vibrates to produce an atomization effect; when the user slides the switch assembly 3 to the closed position, the nozzle 212 is covered, and the disinfection lamp 64 automatically irradiates the nozzle 212; at this time, the elastic conductive element 62 contacts the trigger electrode 63, the disinfection circuit is activated, and timed or continuous sterilization is performed; after the switch assembly 3 is moved out of the closed position, the circuit is automatically disconnected, and the disinfection lamp 64 stops, avoiding energy waste. That is, the sterilization function is automatically triggered or turned off by sliding the switch assembly 3, without additional operation, improving hygiene and safety. In addition, the partition design of the bracket assembly 22 optimizes the layout of the atomizing module 4 and the power supply, making the structure more compact. In other words, through the structural optimization of the outer shell assembly 21 and the bracket assembly 22, the main unit assembly 2 achieves an efficient layout of the atomizing module 4 and the PCB board 8, while ensuring the precise linkage between the sterilization component 6 and the switch assembly 3. It should be noted that the elastic conductive element 62 is only turned on in the off position to prevent accidental activation of the disinfection lamp 64.

[0048] In other embodiments, the bottom wall of the first mounting groove is provided with a positioning boss, and the side of the atomizing module 4 facing the bracket assembly 22 is provided with an assembly groove that matches the positioning boss; the positioning boss engages with the assembly groove, so that the atomizing module 4 can be detachably installed in the first mounting groove, ensuring that the atomizing module 4 is fixed in the first mounting groove, thereby making the atomizing sheet 7 and the nozzle 212 accurately aligned and improving atomization efficiency. The height of the boss is slightly less than the depth of the assembly groove, ensuring that the atomizing module 4 and the bracket assembly 22 fit together without gap after engagement. Specifically, align the assembly groove of the atomizing module 4 with the positioning boss of the bracket assembly 22, and gently press axially until the boss and the bottom of the groove are fully engaged. At this time, the atomizing sheet 7 automatically aligns with the nozzle 212; pinch the sides of the atomizing module 4 and apply force to overcome the friction between the boss and the groove, and it can be removed vertically. That is, through the cooperation of the positioning boss and the assembly groove, the atomizing module 4 is accurately positioned in the bracket assembly 22 and easily disassembled.

[0049] In this embodiment, the housing assembly 21 is further provided with a limiting groove located below the nozzle 212. The limiting groove includes a fixing member 61. The limiting groove constrains the sliding trajectory of the switch assembly 3, ensuring it accurately reaches the open or closed position. The fixing member 61 has an opening slot, providing a movement channel for the free end of the elastic conductive member 62, preventing interference with other components, and isolating the elastic conductive member 62 from other metal components to prevent accidental short circuits. In other words, the limiting groove and the fixing member 61 work together to prevent overshooting or misalignment of the switch assembly 3, ensuring that the elastic conductive member 62 is aligned with the trigger electrode 63.

[0050] In this embodiment, the housing assembly 21 also has a through-hole, which is located within the limiting groove and through which the elastic conductive element 62, such as a metal spring or spring contact, is disposed. Preferably, the elastic conductive element 62 is made of a flexible material to reduce mechanical wear with the trigger electrode 63 and extend its lifespan. The fixed end of the elastic conductive element 62 is connected to the PCB board 8. Preferably, the PCB board 8 can be a built-in power supply or circuit board to maintain continuous power supply capability. When the switch assembly 3 slides to the closed position, the free end of the elastic conductive element 62 moves along the opening groove and abuts against the trigger electrode 63. When the switch assembly 3 slides to the open position, the free end separates from the trigger electrode 63.

[0051] When the switch assembly 3 slides to the closed position, it presses the free end of the elastic conductive element 62, causing it to move along the opening groove toward the trigger electrode 63. After the free end contacts the trigger electrode 63, a closed circuit is formed to conduct the disinfection circuit, and the disinfection lamp 64 is powered on. When the switch assembly 3 slides to the open position, it releases the pressure, and the elastic conductive element 62 retracts due to its own deformation recovery force. The free end disengages from the trigger electrode 63, the disinfection circuit is disconnected, and the atomization function operates independently.

[0052] In other words, the outer casing assembly 21, through the cooperation of the limiting groove, the fixing part 61, and the mounting hole, achieves stable movement and reliable switching of the elastic conductive part 62, ensuring that the sterilization component 6 is activated only when the switch assembly 3 is in the closed position, thus avoiding conduction failure caused by spring failure. In addition, the atomizer achieves intelligent sterilization function with mechanical sliding trigger circuit switching while maintaining a compact structure, taking into account both ease of operation and electrical safety.

[0053] In this embodiment, as Figure 4 As shown, the trigger electrode 63 is a metal spring sheet, and an arched protrusion is provided on the side facing the elastic conductive member 62. The arched protrusion forms a partial contact and conduction with the free end of the elastic conductive member 62.

[0054] The trigger electrode 63 is fixed at both ends to the side of the fixing member 61 near the limiting groove. The arched protrusion faces the opening groove and protrudes. When the free end of the elastic conductive member 62 moves along the opening groove, it abuts against the arched protrusion to form a point contact or a small area contact. The current is conducted through the contact surface between the arched protrusion and the free end, activating the disinfection lamp 64. When the switch assembly 3 is retracted, the free end of the elastic conductive member 62 breaks contact with the arched protrusion, and the circuit is disconnected.

[0055] In other words, the trigger electrode 63 adopts a metal spring structure, and through the design of the arched protrusion, it forms a highly reliable contact with the free end of the elastic conductive element 62, ensuring stable conduction of the sterilization circuit. Furthermore, the circuit can be automatically switched on and off simply by sliding the switch assembly 3, without the need for additional buttons. Even slight displacement ensures circuit continuity, preventing sterilization failure. In addition, the arched protrusion provides elastic cushioning to prevent poor contact when the device shakes.

[0056] In this embodiment, the atomizing module 4 further includes an atomizing shell 41, an atomizing bracket, and a cover plate assembly 43; the atomizing shell 41 has an atomizing chamber and a nozzle 212 communicating with the atomizing chamber, providing an atomizing space; the atomizing shell 41 is provided with a bottom cover, and an atomizing magnet 412 is provided on the side of the bottom cover facing the first mounting groove.

[0057] The atomizing housing 41 has an assembly groove at its bottom for quick module positioning and installation; the atomizing bracket is located in the atomizing chamber and has a liquid inlet channel 42 to control the liquid flow, prevent overflow, and ensure that a uniform liquid film is formed on the surface of the atomizing plate 7; the cover plate assembly 43 is located on the atomizing bracket; the cover plate assembly 43 has a through-flow channel 431, the inlet of which is set corresponding to the atomizing plate 7 and the outlet is connected to the nozzle 212 to directionally transport the atomized particles to the nozzle 212 and reduce eddy current loss.

[0058] In this system, liquid in the storage tank 1 is supplied to the surface of the atomizing plate 7 via the inlet channel 42 of the atomizing bracket through capillary action / gravity. The high-frequency vibration of the atomizing plate 7 breaks the droplets into particles, which are then accelerated through the guide channel 431 of the cover plate assembly 43 and ejected from the nozzle 212. This three-layer modular design—comprising the atomizing shell 41, the atomizing bracket, and the cover plate assembly 43—combines modular, split-structure design with optimized fluid dynamics, achieving efficient liquid atomization and directional delivery. This improves atomization performance while addressing industry pain points such as difficult cleaning and uneven droplet distribution in traditional atomizers.

[0059] In this embodiment, the atomizing plate 7 is disposed between the atomizing bracket and the cover plate assembly 43 by a sealing gasket 5, which prevents unatomized liquid in the liquid inlet channel 42 from seeping out from the joint, while improving the airtightness of the interface of the guide channel 431.

[0060] In this embodiment, the liquid inlet channel 42 includes a first connecting portion 421 and a second connecting portion 422 integrally connected to avoid leakage risks caused by seams. The first connecting portion 421 and the second connecting portion 422 are arranged at an angle. The liquid inlet of the first connecting portion 421, away from the second connecting portion 422, is connected to the liquid storage tank 1. The liquid outlet of the second connecting portion 422, away from the first connecting portion 421, is arranged corresponding to the atomizing plate 7. The aperture size of the first connecting portion 421 gradually decreases along the direction close to the second connecting portion 422, forming a tapered contraction to gradually increase pressure and improve the liquid flow rate. The aperture size of the second connecting portion 422 gradually increases along the direction close to the atomizing plate 7, expanding in a trumpet shape to reduce flow resistance and allow the liquid to be evenly spread on the surface of the atomizing plate 7.

[0061] To elaborate further, the liquid flows naturally from the storage tank 1 through the inlet, and its kinetic energy increases as it passes through the first connecting part 421 of the conical channel, where its flow direction is adjusted in the transition zone. Then, it reaches the second connecting part 422 of the expansion channel, where the flow rate decreases, and the liquid covers the active area of ​​the atomizing plate 7 in a laminar flow state. This combination of gradual fluid cross-section change and bending guidance solves the problems of large flow fluctuations, easy flow interruption when tilted, and low atomization efficiency inherent in traditional atomizers without the need for an external pump, making it particularly suitable for the compact structure requirements of portable atomizing devices. Furthermore, the inner wall of the inlet channel 42 is mirror-polished to reduce liquid adsorption loss.

[0062] In this embodiment, the inner wall of the switch assembly 3 is further provided with a sensing control component 9. The sensing control component 9 is electrically connected to the atomizing plate 7 so that when the switch assembly 3 slides to the closed position, the atomizing plate 7 is de-energized and closed under the sensing action of the sensing control component 9; when the switch assembly 3 slides to the open position, the atomizing plate 7 is energized and opened under the sensing action of the sensing control component 9. This allows the operation of the atomizing plate 7 to be controlled by changing the position of the switch assembly 3, improving convenience. Preferably, the sensing control component 9 includes a Hall switch and a sensing magnet. The sensing magnet is disposed on the inner wall of the switch assembly 3, and the Hall switch is mounted on the host PCB board of the PCB board 8. The sensing magnet can follow the movement of the switch assembly 3 to sense the Hall switch, that is, directly control the gate voltage of the two MOS transistors through the Hall signal to ensure that they are not physically turned on at the same time, thereby realizing the connection and disconnection between the atomizing plate 7 and the power electrode 44 to determine whether atomization is performed.

[0063] In this embodiment, a battery assembly is provided on the side of the receiving cavity near the PCB board 8. The battery assembly is electrically connected to the PCB board 8 to supply power to the PCB board 8, the atomizing sheet 7 of the atomizing module 4, and the disinfection lamp 64 of the sterilization component 6.
