Description

Technical Field

[0001] This utility model relates to an atomizer that produces mist in accordance with the beat, and more specifically, to a structure that combines an atomizer and a music player, in which a speaker is used as an air supply device and an airflow channel is used as a resonant cavity for a music player. Background Technology

[0002] In ultrasonic atomizers and heated evaporative atomizers, the atomizing component is responsible for arousing or evaporating the liquid to be atomized into a mist. Then, air supply devices such as fans, blowers, and air pumps apply air pressure to the air carrying the liquid mist, blowing the liquid mist away so that it can be utilized.

[0003] If the liquid mist is not blown away in time, as atomization continues and the concentration of the liquid mist increases, the liquid mist particles will agglomerate and recombine into larger droplets, falling back into the liquid to be atomized or spilling elsewhere, resulting in low atomization efficiency or atomization failure. Therefore, an air supply device is essential in this type of atomization device.

[0004] Small and medium-sized atomizing devices are mostly used in homes or small to medium-sized public places to improve air humidity. These settings often aim for a relaxed and pleasant atmosphere, with a similar need for music. Traditionally, humidifiers and music players are placed separately, especially in small spaces. This configuration not only occupies a significant amount of space but also requires separate power supplies, which is clearly not the optimal solution. While combining a humidifier and music player simply solves the space and power supply issues, it is the least technologically advanced and cost-effective solution, offering no practical value or improvement in user experience. Utility Model Content

[0005] This invention addresses the limitations of traditional technologies in real life and market demands by providing an atomizer that produces mist in sync with the beat, thus solving the problems of existing technologies.

[0006] Based on practical needs, this specification provides one or more embodiments of an atomizer that emits mist in sync with a beat, overcoming the limitations and defects of the current technology listed in the background section, and providing a practical solution. The technical solution of this utility model is as follows:

[0007] The present invention provides an atomizer that emits mist in time with the beat, comprising a liquid container, an atomizing chamber, an atomizing component, an airflow channel, a mist outlet cover, a speaker, and a control circuit.

[0008] The mist outlet cover is fastened to the top of the liquid container and has a mist outlet on it;

[0009] The liquid container is used to hold the liquid to be atomized, wherein the space above the liquid surface and the mist beam cover is the atomization chamber;

[0010] The atomizing component has its working surface in contact with the liquid to be atomized, which is inside or supplied by the liquid container.

[0011] The airflow channel is a hollow channel, with its first end connected to the atomizing chamber, a speaker installed at the second end, and an air inlet at the root of the second end; the inner diameter of the first end of the airflow channel is smaller than the inner diameter of the second end.

[0012] The control circuit is electrically connected to the atomizing component and the speaker.

[0013] This solution uses a speaker as a blower and an airflow channel as a resonant cavity for a music player, deeply integrating the functions of the atomizer and the music player. This simplifies the structure, reduces the size, and lowers the cost.

[0014] As a further technical solution, the airflow channel is provided with a resonant diaphragm and a replenishment port between the speaker and the air inlet. The replenishment port is located between the resonant diaphragm and the mist outlet, close to the resonant diaphragm.

[0015] This solution can significantly improve the sound quality of music players by adding a resonant diaphragm. The vibration source that drives the airflow is transferred to the resonant diaphragm. Therefore, an air inlet is provided near the resonant diaphragm, and its function is the same as that of the supplementary air inlet.

[0016] As a further technical solution, the airflow channel is provided with at least one pressurization section, which is a guide narrowing section and a widening section arranged sequentially in the airflow direction.

[0017] This design incorporates a structure within the airflow channel that facilitates unidirectional airflow, thereby improving the driving efficiency of the airflow.

[0018] As a further technical solution, the airflow channel is provided with a first diameter reduction section, a sphere, a second diameter reduction section and a diameter expansion section in sequence along the airflow direction; the first diameter reduction section has a smooth and flat opening wall on the side near the sphere; the second diameter reduction section has a groove on the inner wall on the side near the sphere; the sphere is a hollow sphere or a low-density sphere with a halo around its outer wall.

[0019] This design incorporates the aforementioned structure within the airflow channel to create a threshold for airflow movement. Specifically, when the instantaneous air pressure in the airflow channel exceeds this threshold, the sphere rises, the airflow channel becomes unobstructed, and airflow is rapidly discharged from the mist outlet. Conversely, when the instantaneous air pressure in the airflow channel falls below this threshold, the sphere descends, increasing the resistance of the airflow channel or causing it to become blocked, resulting in weakened or suspended airflow at the mist outlet. Because the instantaneous air pressure in the airflow channel is synchronized with the rhythm of the music played by the speaker, this design can precisely control the mist outlet's shape, resulting in a more pronounced rhythmic effect.

[0020] As a further technical solution, the control circuit includes music playback and power amplification circuits.

[0021] This solution combines the functions of an atomizer and a music player into one.

[0022] As a further technical solution, the control circuit includes a frequency generator below 20Hz or above 20kHz, and a driving circuit for the output signal of the frequency generator, used to drive the loudspeaker in a frequency range inaudible to the human ear.

[0023] This solution allows users to ensure that the atomizer can still operate independently when music is not needed.

[0024] As a further technical solution, the mist outlet cover has a shaped tongue inside its mist outlet. The shaped tongue is an island-shaped structure that is set in the inner cavity of the mist outlet and has connecting ribs with the inner cavity of the mist outlet, which is used to constrain the shape of the mist flow output from the mist outlet.

[0025] This solution utilizes a shaped tongue at the mist outlet to shape the mist stream, achieving various mist patterns such as hearts and smoke rings, adding more fun to the product, expanding its application scenarios, and improving the user experience.

[0026] As a further technical solution, the length of the airflow channel is less than 118mm.

[0027] This solution limits the length of the airflow channel, ensuring that the half-wave of the signal driven by the center frequency of the mid-frequency in the music (the main component of the music) (corresponding to the movement of the speaker diaphragm towards the mist outlet), and the standing wave formed in the airflow channel, are all output outside the mist outlet through the entire airflow channel. This reduces the probability of backflow and greatly improves the driving efficiency of the airflow.

[0028] As a further technical solution, a light-emitting device is provided inside the atomizing chamber, directly opposite the mist outlet, with its light emission direction facing the mist outlet.

[0029] This design adds a feature to the atomizer where the emitted mist is illuminated by a light, increasing the product's appeal.

[0030] As a further technical solution, the control circuit is equipped with an infrasound or ultrasonic generator and a music player, the working states of which are switched by the control circuit, so that the drive signal output to the speaker can be selected by the user.

[0031] The advantages of implementing this utility model are:

[0032] ①Using the speaker of a music player as a traditional air supply device (fan, blower, etc.) can simplify the overall structure, reduce the size, and lower the cost;

[0033] ② Added a visual effect to the whole machine, in which the fog dances in sync with the music, improving the user experience and increasing its practical value;

[0034] ③ The airflow channel and the atomization chamber (the space above the liquid surface in the container cavity 17) are used as the speaker resonant cavity, which further simplifies the overall structure, reduces the overall size, and lowers the cost.

[0035] ④ It provides several specific solutions, such as enhancing the fog rhythm effect, brightening the fog flow, switching between music and mute functions, and fog shape, which adds more use value to the product and makes it more practical. Attached Figure Description

[0036] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the accompanying drawings:

[0037] Figure 1 A schematic diagram of the basic structure of an atomizer that produces mist in accordance with the beat;

[0038] Figure 2 A partial structural diagram of an airflow channel with two-stage pressurization sections; Detailed Implementation

[0039] Example 1 - Atomizer that produces mist in sync with the beat

[0040] like Figure 1 As shown, the atomizer that emits mist in sync with the beat consists of a bottom shell (not shown), a middle shell 1, a mist outlet cap 2, a speaker 3, and a control circuit board (not shown). Among these:

[0041] The middle shell 1 is a double-layer structure with openings at the top and bottom. The upper layer has a container 11, and the lower layer has a speaker mounting base 14, an atomizer mounting base (not shown due to angle), a circuit board mounting hole (not shown due to angle), and a bottom shell fixing post 19, etc. There is a mating edge 18 on the outer side between the upper and lower layers, and the inner side is the bottom of the container. There is an atomizer mounting hole on the bottom of the container, and the atomizer 12 is sealed and installed on the atomizer mounting hole on the bottom of the container. Inside the container cavity 17 of the upper container 11, there is an airflow channel 13 that communicates with the speaker mounting base 14. The upper opening 16 is inclined and faces the outer side of the container cavity 17. The inner diameter of the upper opening 16 is smaller than the inner diameter of the lower opening of the airflow channel 13 (speaker mounting base 14). In the lower layer, there is a flow inlet 15 on the side wall of the speaker mounting base 14.

[0042] The mist outlet cover 2 is a cover-shaped structure used to fasten onto the container 11 of the middle shell 1. Its lower opening 21 matches the mating edge 18 of the middle shell 1, and the upper central position is provided with a mist outlet 22.

[0043] The speaker 3 is mounted on the speaker mounting base 14 of the middle shell 1.

[0044] The bottom shell serves as the base of the entire machine and is fixed to the bottom shell fixing post 19 of the middle shell 1 by screws.

[0045] During operation, the liquid to be atomized is poured into the inner cavity 17 of container 11, and the mist jet cover 2 is fastened onto container 11 of the middle shell 1. The control circuit board is activated to operate, applying driving power to the atomizing head 12 and transmitting a music signal to the speaker 3. The atomizing head 12 vibrates at high frequency, exciting the liquid to be atomized in contact with it, causing it to form a mist above the liquid surface; at the same time, the diaphragm of the speaker 3 vibrates back and forth with the music being played, and this vibration drives the air column inside the airflow channel 13 to generate a standing wave that moves up and down along a straight line inside it. Since the speed of sound in air is about 340m / s, and taking the mid-frequency center of music, 720Hz, as a reference, when the length of the airflow channel 13 is less than 236mm, the head of the upward standing wave generated by the diaphragm of the speaker 3 each time it vibrates upward within the airflow channel 13 can move from the front of the speaker, through the entire airflow channel 13, to the upper opening 16; while when the length of the airflow channel 13 is less than 118mm, the entire upward vibration wave generated by the diaphragm of the speaker 3 each time it vibrates upward within the airflow channel 13 can completely pass through the upper opening 16 and reach above the liquid surface in the inner cavity 17 of the container. Subsequently, because the inner diameter of the upper opening 16 of the airflow channel 13 is smaller than the inner diameter of the lower opening (speaker mounting base 14), the diaphragm of the speaker 3 moves upward, driving a half-standing wave in the airflow channel 13. After the air passes through the upper opening 16, the diaphragm of the speaker 3 moves downward, generating a negative pressure in the lower part of the airflow channel 13. The nearest inlet 15 preferentially flows into the lower part of the airflow channel 13 to fill the negative pressure. This cycle continues, and the speaker generates an upward driving pressure in the airflow channel 13, driving air to flow in from the inlet 15, through the airflow channel 13, and from the upper opening 16 to the liquid surface in the container cavity 17, carrying the liquid mist in this space, and flowing out from the mist outlet 22 of the mist outlet cover 2, forming a visible mist stream.

[0046] At the beat of the music, the audio frequency or intensity changes, causing a sudden change in the frequency or amplitude of speaker 3, and the air pressure or flow rate it drives also changes synchronously. This manifests as a synchronous change in the mist flow at the mist outlet 22. In other words, the strength of the mist flow at the mist outlet 22 can be synchronized with the beat of the music, adding interest to the atomizer.

[0047] The advantages of implementing this embodiment are:

[0048] ①Using the speaker of a music player as a traditional air supply device (fan, blower, etc.) can simplify the overall structure, reduce the size, and lower the cost;

[0049] ② Added a visual effect to the whole machine, in which the fog dances in sync with the music, improving the user experience and increasing its practical value;

[0050] ③ The airflow channel and the atomization chamber (the space above the liquid surface in the container cavity 17) are used as the speaker resonant cavity, which further simplifies the overall structure, reduces the overall size, and lowers the cost.

[0051] Other embodiments

[0052] In another embodiment, the airflow channel is provided with multiple pressurization stages, such as... Figure 2 As shown, the airflow channel 4 is composed of a speaker mounting base 41, a speaker mounting port 42, a main channel 43, a supplementary flow port 44, a first guide plate 45, a first buffer chamber 46, a second guide plate 47, and a second buffer chamber 48. The first guide plate 45 and the first buffer chamber 46 constitute a first-stage pressurization section, and the second guide plate 47 and the second buffer chamber 48 constitute a second-stage pressurization section.

[0053] The speaker diaphragm faces the main channel 43 and is mounted on the speaker mounting port 42. When the speaker diaphragm moves upward, the resulting standing wave propagates in a straight line along the centerline of the speaker. The air inside the airflow channel 4 is compressed upward and moves upward, with a portion moving straight upward along the central main channel 43. In the first-stage pressurization section, another portion of the air is constrained by the first guide plate 45 and moves towards the first buffer chamber 46. The first guide plate 45 creates the first narrowing within the airflow channel 4, and the first buffer chamber 46 then creates the first widening within the airflow channel 4. This allows the airflow section, which has been given positive pressure by the speaker, to achieve its first pressure balance within the first buffer chamber 4, reducing the force of its reverse backflow.

[0054] Within the secondary pressurization stage, the second guide vane 47 and the second buffer chamber 48 are positioned opposite the first guide vane 45 and the first buffer chamber 46, ensuring that the main channel 43 between them in the center is straight, thus reducing flow resistance. The airflow movement within the secondary pressurization stage is analogous to its movement within the primary pressurization stage. The multi-stage pressurization design allows the airflow pressure to be balanced multiple times and gradually reduces the backflow force, effectively functioning as a one-way valve.

[0055] The advantage of implementing this embodiment is that by upgrading the structure of the airflow channel, the driving efficiency of the airflow is further improved.

[0056] In another embodiment, the control circuit board includes an infrasound or ultrasonic generator and a music player, the operating states of which are switched by the control circuit so that the drive signal output to the speaker can be selected by the user.

[0057] In this embodiment, it is preferably applied to solutions that combine airflow drive with a music player, such as atomizers or air delivery mechanisms with music players. During operation, when the user selects simultaneous music playback and air delivery, the speaker is driven by a music signal, allowing both functions to operate concurrently. When the user selects silent operation, the system switches to infrasound or ultrasonic drive to ensure normal air delivery, but the speaker's vibration frequency remains within the audible range, thus considered silent.

[0058] The benefits of implementing this embodiment are that it improves the functional configuration of the atomizer + music player combo product, making it compatible with more application scenarios.

In some cases, the structure described in the claims can be used to achieve the desired results according to the specific embodiments described above.

For those skilled in the art, the techniques of one or more embodiments of this specification can be combined in new ways to achieve new implementations, or various modifications and variations can be made. Any modifications, equivalent substitutions, improvements, technical combinations, etc., made within the spirit and principles of one or more embodiments of this specification should be included within the scope of the claims of this specification.
