Technical Field

[0001] This utility model relates to the field of atomizer technology, and in particular to an air duct structure and an atomizer. Background Technology

[0002] The common airflow configuration of existing large humidifiers is that the fan is placed horizontally downwards and blows directly at an angled baffle.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0030] like Figures 1 to 4 As shown, this utility model embodiment provides a duct structure, including a fan 4 and a guide plate 2. The fan 4 is located on the windward side of the guide plate 2. The windward side of the guide plate 2 is provided with an arc-shaped guide surface 221. The exhaust direction of the fan 4 is towards the arc-shaped guide surface 221. The guide plate 2 is also provided with an air guide hole 23, which penetrates the windward side and the leeward side of the guide plate 2.

[0031] The fan 4 can be an axial flow fan or a centrifugal fan, etc. The windward side of the air guide plate 2 is provided with an arc-shaped guide surface 221. This arc-shaped guide surface 221 effectively optimizes the airflow trajectory. Specifically, when the exhaust direction of the fan 4 faces the arc-shaped guide surface 221, the arc-shaped guide surface 221 can buffer and guide the airflow. Without the arc-shaped guide surface 221, the airflow discharged from the fan 4 would directly impact the plane, generating a large rebound force and causing airflow turbulence. However, with the arc-shaped guide surface 221, the airflow can flow more smoothly along the arc surface, reducing wind rebound and lowering airflow resistance.

[0032] The air guide holes 23 are designed to better guide the airflow. The size and number of air guide holes 23 can be determined according to the actual situation. In this embodiment, there are three air guide holes 23. The air guide holes 23 can reasonably disperse the airflow discharged from the fan 4, allowing the airflow to pass more smoothly through the air guide plate 2 and enter the subsequent atomization chamber 13 and other areas, thereby ensuring smooth air pressure in the atomization chamber 13 and effectively increasing the mist output rate.

[0033] Furthermore, the apex of the arc-shaped guide surface 221 is located at the center of the arc-shaped guide surface 221 and faces the exhaust direction of the fan 4. This design allows the airflow to be subjected to more uniform force when it impacts the arc-shaped guide surface 221, further improving the air guiding effect.

[0034] Furthermore, such as Figure 4 As shown, the air guide plate 2 includes a first air guide section 21 and a second air guide section 22 arranged at an angle. The first air guide section 21 is arranged parallel to the exhaust direction of the fan 4, and the second air guide section 22 is arranged opposite to the exhaust direction of the fan 4.

[0035] The first air guide section 21 and the second air guide section 22 can be manufactured using an integral molding process, through injection molding or metal stamping, to ensure structural strength and stability.

[0036] The first air guide section 21 is arranged parallel to the exhaust direction of the fan 4. This design enables the airflow discharged from the fan 4 to be initially guided and diverted when it comes into contact with the first air guide section 21. When the airflow from the fan 4 reaches the first air guide section 21, the airflow will be guided to change direction and flow towards the second air guide section 22.

[0037] The second air guide section 22 is positioned opposite to the exhaust direction of the fan 4, and the windward side of the second air guide section 22 is provided with an arc-shaped guide surface 221. This design serves two purposes: firstly, the airflow directly blown by the fan 4 onto the arc-shaped guide surface 221 of the second air guide section 22 is guided to both sides; secondly, when the airflow, after being diverted and guided by the first air guide section 21, reaches the second air guide section 22, the arc-shaped guide surface 221 further buffers and guides the airflow, allowing the air to pass more smoothly through the air guide plate 2, thereby reducing airflow turbulence and noise.

[0038] Furthermore, such as Figure 4 As shown, the air guide hole 23 is located at the corner of the first air guide section 21 and the second air guide section 22. This design allows the air guide hole 23 to effectively balance the air pressure difference between the two air guide sections, guiding the airflow to transition more smoothly. When the airflow discharged from the fan 4 is turned after passing through the first air guide section 21, some of the airflow will pass directly through the corner via the air guide hole 23, avoiding accumulation at the corner and allowing the airflow to flow evenly and smoothly towards the arc-shaped guide surface 221 of the second air guide section 22.

[0039] To further improve the smooth flow of air, the corners of the first air guide 21 and the second air guide 22 are chamfered so that the airflow reaching this position can transition smoothly.

[0040] like Figures 1 to 4As shown, this utility model embodiment also provides an atomizer, including a shell 1, an air inlet 11, an atomizing chamber 13, a mist outlet 12, and the aforementioned air duct structure. The air inlet 11 and the mist outlet 12 are disposed on the surface of the shell 1, the atomizing chamber 13 is located inside the shell 1, the air inlet 11 is disposed on the suction side of the fan 4, the atomizing chamber 13 is disposed on the leeward side of the air guide plate 2, the mist outlet 12 is connected to the atomizing chamber 13, and the bottom of the air guide plate 2 is provided with an air inlet channel 3 that communicates with the atomizing chamber 13.

[0041] The air inlet 11 serves as the channel for the atomizer to draw in air and is located on the suction side of the fan 4. The shape of the air inlet 11 can be circular, square, etc., and its size needs to be designed to match the air intake of the fan 4.

[0042] The air inlet 11 is angled to the suction side of the fan 4. This design allows air to be naturally drawn into the fan 4 after entering through the air inlet 11, preventing the formation of airflow vortices at the air inlet 11 and reducing airflow resistance. In addition, the air inlet cavity 5 can serve as a buffer and pressure stabilizer.

[0043] The atomizing chamber 13 is the core area for realizing the atomization function. An atomizing core 131 is arranged at the bottom of the atomizing chamber 13. The atomizing core 131 can be an ultrasonic atomizing plate or a heated atomizing component, etc. When a stable airflow enters the atomizing chamber 13, the atomizing core 131 vibrates the liquid into tiny particles, which mix with the airflow to form a mist.

[0044] To further optimize the fogging effect, a fog-gathering channel is provided between the atomizing chamber 13 and the fog outlet 12. The size of the fog-gathering channel gradually decreases along the direction from the atomizing chamber 13 to the fog outlet 12. This structure enables the fog mixture to further converge and accelerate when passing through the fog-gathering channel, thereby increasing the concentration and speed of fogging and thus increasing the fogging rate.

[0045] Furthermore, the air inlet 11 is set at an angle to the air intake side of the fan 4, and an air inlet cavity 5 is provided between the air inlet 11 and the fan 4.

[0046] In this embodiment, the air inlet 11 faces downwards, and the air inlet 11 is designed at a 90-degree angle to the suction side of the fan 4. This angle design allows the outside air to flow towards the fan 4 at a suitable angle after entering the air inlet 11, reducing the eddies and resistance generated by the air directly impacting the suction side of the fan 4 at the air inlet 11. At the same time, the air inlet cavity 5 set between the air inlet 11 and the fan 4 can play a role in buffering and stabilizing pressure. When air flows into the air inlet cavity 5 from the air inlet 11 at a certain angle, the air velocity will decrease due to the sudden expansion of the space. This allows the airflow, which may have had uneven velocity, to be mixed and adjusted within the air inlet cavity 5, thereby forming a relatively stable and uniform airflow entering the fan 4. In addition, the air inlet cavity 5 can also reduce the noise generated by the fan 4 during operation to a certain extent. Through the reflection and absorption of sound waves by the inner wall of the cavity, the propagation of noise to the outside is reduced.

[0047] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
