Technical Field

[0001] This application relates to the field of electronic atomization technology, and in particular to an ultrasonic atomizing device and electronic atomization equipment. Background Technology

[0002] Electronic atomizing devices are electronic products that mimic cigarettes, producing similar smoke, taste, and sensation. They convert atomized liquid into an aerosol for users to inhale.

[0003] Among related technologies, ultrasonic atomization technology is gradually being applied to electronic atomization devices. The ultrasonic atomization structure generally includes a liquid guiding rod and a piezoelectric ceramic atomizing plate. The liquid guiding rod guides the atomized liquid to the surface of the atomizing plate, and atomization is achieved through the high-frequency vibration of the atomizing plate.

[0004] However, because the liquid guide rod and atomizing plate typically have a microporous structure, and the ultrasonic atomizing liquid (such as an water-based solution containing flavorings and sweeteners) has low viscosity and high fluidity, when the external environment changes (such as high temperature or low pressure), the liquid in the storage chamber can easily seep out through the micropores of the liquid guide rod and atomizing plate and flow out of the device through the nozzle channel, causing leakage, which affects the user experience and the service life of the device. Utility Model Content

[0005] Therefore, it is necessary to provide an ultrasonic atomizing device and electronic atomizing equipment that can effectively prevent leakage in order to address the above-mentioned technical problems.

[0006] This application provides an ultrasonic atomizing device, comprising: a housing, a nozzle, an ultrasonic atomizing assembly, and a sealing assembly.

[0009] In one embodiment, the sealing cylinder includes a first sealing part and a second sealing part; wherein, the first sealing part is located at the top of the sealing cylinder and abuts against the lower surface of the atomizing plate to seal the outlet end of the first atomizing channel; the second sealing part is a flange extending outward from the outer wall of the sealing cylinder, and the flange is clamped and fixed between the nozzle and the fixing frame along the height direction of the ultrasonic atomizing device.

[0010] In one embodiment, the sealing assembly further includes a second sealing ring; the second sealing ring has an annular structure, is sleeved on the outer periphery of the fixing frame, and is clamped between the suction nozzle and the fixing frame along the radial direction of the ultrasonic atomizing device to seal the connection between the suction nozzle and the fixing frame.

[0011] In one embodiment, the sealing assembly that mates with the fixture includes a first sealing cap; the first sealing cap is installed at the end of the fixture away from the nozzle and closes the bottom opening of the fixture for sealing the bottom of the liquid storage chamber.

[0012] In one embodiment, the side wall of the fixing frame is provided with an injection hole that communicates with the liquid storage chamber, and the housing is provided with an opening corresponding to the injection hole; the sealing assembly also includes an injection plug, which passes through the opening and is detachably sealed in the injection hole.

[0013] In one embodiment, the nozzle and the first sealing ring together form an air outlet communicating with the first atomization channel; the sealing assembly also includes a removable sealing plug, the sealing plug including a plug body portion; wherein, the plug body portion is adapted to the air outlet, and the bottom end of the plug body portion is embedded in the first sealing ring and abuts against the first sealing ring for sealing.

[0014] In one embodiment, the outer surface of the housing is provided with a fixing part, and the sealing plug further includes a connecting strap; one end of the connecting strap is connected to the plug body part, and the other end is connected to the fixing part, so as to secure the sealing plug to the housing.

[0020] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application. Similarly, the following embodiments are only some, not all, embodiments of the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] The directional terms used in this description, such as "up," "down," "left," "right," "inner," and "outer," are only for reference to the directions shown in the attached diagram. These directional terms should be changed if the directions in the attached diagram change.

[0023] The first aspect of this application provides an ultrasonic atomizing device 10, please refer to... Figures 1 to 4 .

[0024] like Figure 1 and Figure 2 As shown, the ultrasonic atomizing device 10 includes a housing 100. The housing 100 serves as the main support structure of the device, and its interior is provided with a liquid storage chamber for storing the atomizing liquid. Specifically, in this embodiment, the housing 100 has two independent liquid storage spaces: a first liquid storage chamber 511 located above and a second liquid storage chamber 512 located below. It should be noted that this application does not strictly limit the specific number of liquid storage chambers; in other embodiments, a single chamber or more liquid storage chambers may be provided according to actual needs.

[0025] The ultrasonic atomizing device 10 also includes a suction nozzle 200. The suction nozzle 200 is located at one end of the housing 100 (the top as shown in the figure) for the user to draw in air. The suction nozzle 200 has a first atomization channel 221 inside, which is connected to the first liquid storage chamber 511 for transferring the atomized aerosol.

[0026] Meanwhile, the ultrasonic atomizing device 10 also includes an ultrasonic atomizing component, which mainly includes an atomizing plate 310 and a liquid guiding rod 320. The atomizing plate 310 is disposed in the first atomizing channel 221, and one end of the liquid guiding rod 320 abuts against the atomizing plate 310, while the other end extends downward into the first liquid storage chamber 511. The function of the ultrasonic atomizing component is to guide the atomized liquid in the first liquid storage chamber 511 to the surface of the atomizing plate 310 using the liquid guiding rod 320, and to disperse the liquid into micron-sized aerosols through the high-frequency vibration of the atomizing plate 310.

[0027] In one embodiment, the atomizing liquid stored in the first liquid reservoir 511 for use by the ultrasonic atomizing component mainly consists of water, and may also include cooling materials such as mint, mainly to provide users with a moist and cool suction experience.

[0028] In addition, the ultrasonic atomizing device 10 also includes a sealing assembly. The sealing assembly is used to cooperate with any of the nozzle 200, the housing 100, and the ultrasonic atomizing assembly to form a sealing structure inside the device or at the joints of the components, preventing the atomized liquid in the reservoir from leaking to the outside of the device.

[0029] Continue reading Figures 1 to 4 To ensure the sealing performance and atomization efficiency of the ultrasonic atomizing assembly during operation, in one embodiment, the sealing assembly specifically includes a first sealing ring 411 and a sealing cylinder 420. These two components are typically made of elastic soft materials such as silicone or rubber. They not only provide a physical seal but also absorb mechanical noise generated by the high-frequency vibration of the atomizing plate 310 to a certain extent.

[0030] The specific fit is as follows: the first sealing ring 411 is located at the end of the first atomizing channel 221 away from the first liquid storage chamber 511 (i.e., the top end), while the sealing cylinder 420 is embedded inside the nozzle 200. The atomizing plate 310 is sandwiched between the first sealing ring 411 and the sealing cylinder 420. This clamping structure has the following two advantages: on the one hand, by utilizing the interference fit of the soft rubber, it can effectively prevent the atomized liquid or aerosol from overflowing from the side gaps of the atomizing plate 310, ensuring that the atomized product can only be transported upward along the preset path; on the other hand, this structure stably defines the position of the atomizing plate 310, keeping it in a horizontal position and avoiding the atomization effect being affected by vibration and displacement.

[0031] Furthermore, the sealing cylinder 420 structurally serves a sealing function. Extending axially, the hollow internal structure of the sealing cylinder 420, together with the liquid guide rod 320, forms the first atomization channel 221. The upper part of the liquid guide rod 320 extends into and passes through the sealing cylinder 420, and the inner wall of the sealing cylinder 420 surrounds the outer circumference of the liquid guide rod 320; the annular gap formed between them is the path for aerosol flow. At the top of the suction nozzle 200, the inner wall of the suction nozzle 200 and the first sealing ring 411 together form the first air outlet 211. The first air outlet 211 and the first atomization channel 221 within the sealing cylinder 420 are coaxially aligned and connected in the vertical direction, thus forming a smooth, straight-through air path. This helps reduce condensation and wall adhesion of aerosols during transmission, increasing the mist output.

[0032] In one embodiment, to ensure the continuous stability of the ultrasonic atomization process, the ultrasonic atomization assembly further includes a spring 330. For example... Figure 2 and Figure 4 As shown, spring 330 is located at the bottom of liquid guide rod 320. In the assembled state, spring 330 is in a compressed and energy-storing state, constantly applying a resisting force towards atomizing plate 310 to liquid guide rod 320. Considering the potential dimensional shrinkage or subsidence of liquid guide rod 320 (typically made of microporous cotton) under long-term immersion or vibration conditions, the continuous pressing of spring 330 ensures that the top surface of liquid guide rod 320 is always in close contact with the lower surface of atomizing plate 310, thereby ensuring that the atomized liquid can be continuously supplied to atomizing plate 310 through capillary action, avoiding "dry burning" or atomization interruption due to poor contact.

[0033] See Figure 6 and Figure 7 Furthermore, the ultrasonic atomizing device 10 also includes a mounting bracket 500. The mounting bracket 500, serving as the internal framework of the device, is installed inside the housing 100. The main function of the mounting bracket 500 is to physically divide and support the internal space of the device. Specifically, the mounting bracket 500 divides the inner cavity of the housing 100 into an upper ultrasonic atomizing chamber (for accommodating the sealing cylinder 420 and the ultrasonic atomizing components) and a lower first liquid storage chamber 511. This separation design helps to isolate circuit components (such as batteries and circuit boards) from the liquid storage area, thereby reducing the risk of short circuits due to leakage.

[0034] In one embodiment, the fixing frame 500 has a through hole 520. The through hole 520 penetrates the fixing frame 500 in a vertical direction. Figure 2The liquid guide rod 320 passes through the through hole 520, thereby spanning the fixing frame 500 and connecting the upper atomizing plate 310 and the lower first liquid storage chamber 511. The diameter of the through hole 520 is designed to match the outer diameter of the liquid guide rod 320, allowing the liquid guide rod 320 to make a small axial displacement under the action of the spring 330, while also providing radial restraint to prevent it from tilting excessively when the device shakes.

[0035] In one embodiment, the mounting bracket 500 is further provided with a pressure relief hole 530. The pressure relief hole 530 is located adjacent to the through hole 520 and connects the first liquid storage chamber 511 with the space above the mounting bracket 500. The function of the pressure relief hole 530 is to balance the air pressure inside and outside the first liquid storage chamber 511. Specifically, as the ultrasonic atomizing component operates, the atomized liquid in the first liquid storage chamber 511 is gradually consumed, and negative pressure is easily formed inside the chamber. Without a pressure relief structure, negative pressure will hinder the upward transport of the atomized liquid along the guide rod 320, resulting in insufficient liquid supply. The pressure relief hole 530 allows external air to enter the first liquid storage chamber 511 to fill the volume after the liquid is reduced, thereby maintaining stable air pressure inside the chamber and ensuring that the guide rod 320 can continuously and stably draw in the atomized liquid.

[0036] In one embodiment, a liquid injection hole 540 is also provided on the side wall of the mounting bracket 500. The liquid injection hole 540 is directly connected to the first liquid storage chamber 511. This design enables the ultrasonic atomizing device 10 to have a refillable liquid function. The user can replenish the atomizing liquid into the first liquid storage chamber 511 through the liquid injection hole 540, thereby extending the service life of the device.

[0037] In one embodiment, to facilitate the injection operation, the housing 100 is provided with an opening 110 corresponding to the injection hole 540 (see...). Figure 5 The sealing assembly may also include an injection plug 440, which passes through the opening 110 and is removably sealed within the injection hole 540 to maintain a seal and prevent leakage. The injection plug 440 can be removed during injection.

[0038] In addition, the mounting bracket 500 is provided with an air inlet 550. The air inlet 550 is mainly used for the passage of components of the heating atomization system (which will be described in detail in subsequent embodiments).

[0039] Continue reading Figure 2 , Figure 3 and Figure 4 In one embodiment, in order to further improve the sealing performance of the internal flow channel, the sealing cylinder 420 may have a special structural design, specifically including a first sealing part 421 located at the top and a second sealing part 422 located on the outside of the cylinder body.

[0040] The first sealing part 421 is located at the top of the sealing cylinder 420, and its end face directly abuts against the lower surface of the atomizing plate 310. Since the sealing cylinder 420 is usually made of elastic materials such as silicone, the first sealing part 421 will undergo a slight elastic deformation under assembly pressure, thereby forming a tight fit with the atomizing plate 310. This fit seals the outlet end of the first atomizing channel 221, ensuring that the atomized aerosol can only be discharged upward through the first air outlet 211, and will not enter the internal cavity of the nozzle 200 from the lower edge of the atomizing plate 310, effectively preventing the risk of internal short circuit or side leakage caused by the accumulation of condensate.

[0041] The second sealing part 422 is a flange structure (or stepped structure) extending outward from the outer wall of the sealing cylinder 420. This flange is clamped and fixed between the bottom surface of the suction nozzle 200 and the top surface of the fixing frame 500 along the height direction of the ultrasonic atomizing device 10. This "upper and lower clamping" fixing method has the following advantages: on the one hand, it locks the position of the sealing cylinder 420 in the axial direction, preventing it from shifting under the pressure of the liquid guide rod 320 or the spring 330; on the other hand, the flange deformed by pressure forms a reliable sealing interface at the connection between the suction nozzle 200 and the fixing frame 500, blocking the path of leakage of the atomized liquid along the outer wall of the sealing cylinder 420.

[0042] Furthermore, in one embodiment, the sealing assembly may also include a removable sealing plug 450. For example... Figure 3 and Figure 4 As shown, the sealing plug 450 is mainly composed of a plug body 451 and a connecting band 452.

[0043] The shape of the plug portion 451 is adapted to the first air outlet 211 on the nozzle 200. When the device is not in use (such as during transportation or carrying), the user can insert the plug portion 451 into the first air outlet 211. It should be noted that the bottom end of the plug portion 451 needs to be able to pass through the wall thickness of the nozzle 200, partially embedded in the inner hole of the first sealing ring 411, and form an interference fit with the first sealing ring 411. This "embedded" sealing design directly blocks the first air outlet 211 of the first atomization channel 221 from the outside, structurally cutting off the leakage path, thereby ensuring that the device can achieve a sealed state under various conditions.

[0044] To improve user experience and prevent accidental loss of the sealing plug 450 during use, in one embodiment, a fixing part 120 is provided on the exterior (e.g., the top side) of the housing 100. One end of the connecting strap 452 is integrally formed or fixedly connected to the plug body 451, while the other end is sleeved or fastened to the fixing part 120. With this securing structure, the sealing plug 450 is always suspended beside the housing 100, which is convenient for use at any time and avoids the inconvenience of losing accessories.

[0045] See Figure 2 , Figure 3 and Figure 6 In one embodiment, the sealing assembly further includes a second sealing ring 412. The second sealing ring 412 has an annular structure and is fitted onto the outer periphery of the top of the mounting bracket 500. After the device is assembled, the second sealing ring 412 is located at the connection between the nozzle 200 and the mounting bracket 500. Specifically, the second sealing ring 412 is radially clamped between the inner wall surface of the nozzle 200 and the outer wall surface of the mounting bracket 500. Through this radial compression fit, the second sealing ring 412 fills the assembly gap between the nozzle 200 and the mounting bracket 500, thereby sealing the connection and preventing liquid or gas from leaking out from the joint.

[0046] Furthermore, to achieve a bottom seal of the liquid storage space, in one embodiment, the sealing assembly cooperating with the bracket 500 further includes a first sealing cap 431. For example... Figure 2 and Figure 6 As shown, the first sealing cap 431 is installed at the end of the fixture 500 away from the nozzle 200. The shape of the first sealing cap 431 is adapted to the shape of the opening at the bottom of the fixture 500, and its edge is tightly fitted to the inner wall of the fixture 500, thereby sealing the bottom opening of the fixture 500.

[0047] In this configuration, the structure of the first liquid storage chamber 511 is defined. The sidewalls of the first liquid storage chamber 511 are formed by the fixing frame 500, the top is defined by the sealing cylinder 420, the injection plug 440, and the upper structure of the fixing frame 500, and the bottom is defined by the first sealing cover 431. The first sealing cover 431 not only serves to seal and prevent leakage but also acts as a load-bearing component. Please refer to [link / reference]. Figure 2 The spring 330 at the bottom of the liquid guide rod 320 abuts against the upper surface of the first sealing cover 431 and the bottom end of the liquid guide rod 320, thereby providing a continuous upward support force for the liquid guide rod 320.

[0048] In order to provide the electrical energy and control signals required for the operation of the ultrasonic atomizing components (and possibly the heating atomizing system), in one embodiment, the ultrasonic atomizing device 10 may include a power supply module.

[0049] Please refer to the following: Figure 2 and Figure 8 The power module includes a bracket 740 disposed at the bottom of the housing 100. The internal space of the bracket 740 defines a battery compartment 741 for mounting and securing the battery 710. To protect the battery 710 and prevent it from shifting or being damaged within the housing 100, the battery 710 is surrounded by a covering 730 (such as cushioning foam or insulating sticker). The battery 710, as an energy storage element, is electrically connected to the atomizing plate 310 to provide driving voltage.

[0050] The power module may also include a circuit board 720 for integrating control circuitry (such as a microcontroller, power drive chip, etc.). In this embodiment, the circuit board 720 is vertically disposed within the housing 100 along the height direction of the ultrasonic atomizing device 10. A clamping plate 140 is provided inside the device to securely fix the circuit board 720. Figure 2 As shown, the circuit board 720 is clamped between the clamping plate 140 and the side wall of the fixing frame 500. This clamping and fixing method saves space and ensures the stability of the circuit board 720. The clamping plate 140 and the housing 100 are fixedly connected by fasteners (such as screws) to realize the assembly of the whole component.

[0051] In addition, in order to achieve airflow triggering (such as detecting the suction action through the microphone) and to provide air for the atomization process, an air inlet 130 is provided at the bottom of the housing 100. External air can enter the device through the air inlet 130 and flow through the sensor area on the circuit board 720, thereby triggering the power module to control the ultrasonic atomization component to start working.

[0052] See Figure 2 and Figure 6 In one embodiment, the sealing assembly may further include a second sealing cap 432. The second sealing cap 432 is mounted at the bottom end of the mounting bracket 500 (i.e., below the first sealing cap 431). Structurally, the second sealing cap 432, the first sealing cap 431, and the lower sidewall of the mounting bracket 500 together define a second liquid storage chamber 512. The second liquid storage chamber 512 is provided independently of the first liquid storage chamber 511 and is used to store different types of atomizing liquids (e.g., atomizing liquids adapted for heated atomization), thereby enabling the device to store multiple media.

[0053] Furthermore, the ultrasonic atomizing device 10 may also include other heating atomizing systems (specific heating elements are not shown in detail in the figure, but are collectively referred to as heating atomizing systems) to cooperate with the second liquid storage chamber 512. In order to achieve independent transmission of heated atomized aerosol, a dedicated airflow channel is designed inside the device.

[0054] Combination Figure 3 , Figure 6 and Figure 7 The mounting bracket 500 has an air supply hole 550. An air supply pipe 560 passes through the air supply hole 550 and vertically through the first liquid storage chamber 511. An air supply channel 561 is formed inside the air supply pipe 560, which connects the lower heating atomization area with the upper suction nozzle 200.

[0055] Correspondingly, in addition to the first atomizing channel 221 mentioned above, the nozzle 200 also has a second atomizing channel 222 arranged side by side, and a second air outlet 212 communicating with the second atomizing channel 222 is opened at the top of the nozzle 200. The top of the air supply tube 560 is inserted into the bottom of the nozzle 200 and docks with the second atomizing channel 222, thereby constructing a complete air outlet path that is independent of the ultrasonic atomization path.

[0056] Further, see Figure 3 A liquid-absorbing component 570 (such as oil-absorbing cotton) is also provided at the connection between the gas delivery pipe 560 and the suction nozzle 200. The liquid-absorbing component 570 is arranged around the gas delivery channel 561 to absorb the condensate generated during the aerosol transmission process, preventing the condensate from accumulating and clogging the channel or being inhaled by the user.

[0057] With the above design, the atomized liquid in the second liquid storage chamber 512, after being heated and atomized, can be output through the gas delivery channel 561 and the second atomization channel 222, and then mixed with the ultrasonic atomized aerosol (such as low-temperature humidified gas) generated in the first liquid storage chamber 511 in the oral cavity or inhaled separately. This dual-system combination not only enriches the aerosol's texture but also alleviates the dryness caused by heating and atomization through the ultrasonic atomized liquid (such as peppermint water), significantly improving the user experience.

[0058] The ultrasonic atomizing device 10 provided in the first aspect of this application constructs a leak-proof system by setting a sealing component and making it closely cooperate with the nozzle 200, the housing 100 and the ultrasonic atomizing component. Specifically, by utilizing the cooperation between the first sealing ring 411 and the sealing cylinder 420, the atomizing plate 310 is clamped between the two, which not only fixes the atomizing plate 310, but also effectively prevents the atomizing liquid from seeping out from the side gaps of the atomizing plate 310; by utilizing the flange extending from the outer wall of the sealing cylinder 420 (i.e., the second sealing part 422), it is clamped between the nozzle 200 and the fixing frame 500, sealing the outer boundary of the first atomizing channel 221; by utilizing the second sealing ring 412, it is radially clamped between the nozzle 200 and the fixing frame 500, sealing the connection and mating of the upper components of the device; by utilizing the first sealing cover 431 to seal the bottom of the fixing frame 500, a reliable seal is achieved at the bottom of the first liquid storage chamber 511; by utilizing the liquid injection plug 440 to seal the liquid injection hole 540, both the convenience of liquid injection and the leak-proof performance are taken into account; by utilizing the detachable sealing plug 450, its plug body part 451 is partially embedded in the inner hole of the first sealing ring 411, physically blocking the first air outlet 211. The combined effect of the above-mentioned multiple sealing structures can effectively block the risk of leakage of atomized liquid in various paths, and can ensure the sealing performance of the device even in environments such as high temperature, low pressure transportation or violent shaking.

[0059] A second aspect of this application provides an electronic atomizing device, including a heated atomizing device 600 and an ultrasonic atomizing device 10 according to any embodiment of the first aspect described above. The mouthpiece 200 has a second atomizing channel 222, which is independent of and arranged side-by-side with the first atomizing channel 221. The aerosol generated by the heated atomizing device 600 is transported to the second atomizing channel 222 through an air delivery channel 561 formed inside the air delivery pipe 560, and then inhaled by the user. This electronic atomizing device combines ultrasonic atomization and heated atomization, providing a richer inhalation experience.
