Description

Technical Field

[0001] This utility model relates to the field of humidifiers, and in particular to a humidifier that prevents water accumulation. Background Technology

[0002] In modern living environments, humidifiers are widely used as a common household appliance to improve indoor air humidity and enhance living comfort. Among them, mist-generating humidifiers are favored by consumers because they can directly produce mist, enhancing the visual and sensory experience of the room. The working principle of this type of humidifier is mainly based on the conversion of electrical energy into mechanical energy, as well as the physical decomposition and diffusion process of water molecules.

[0003] Specifically, mist-type humidifiers use a built-in transducer as their core component. When powered on, this transducer efficiently converts electrical energy into high-frequency mechanical vibration energy. This vibration acts on the water in the humidifier's tank, causing water molecules to be subjected to a strong impact force and broken down into extremely fine water vapor particles, commonly known as "mist." These tiny water vapor particles are then carried by the airflow generated by the humidifier's internal air duct system and evenly dispersed into the indoor air, thus achieving the purpose of humidification.

[0004] However, while mist humidifiers are highly effective at increasing indoor humidity and their mist can add warmth and vibrancy to the indoor environment, they also reveal some problems during operation. Because water vapor particles are continuously blown into the air, the humidifier can easily cause excessively high humidity in localized areas. Water can accumulate on the floor around the humidifier and on the surface where it is placed, especially after prolonged operation. This not only affects aesthetics but can also create safety hazards, such as an increased risk of slipping and damage to electrical equipment due to moisture. Therefore, how to reduce or avoid these problems while maintaining effective humidification has become a pressing technical challenge in the design and improvement of mist humidifiers. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned technical problems and provide a humidifier that prevents water accumulation. This application aims to avoid the problem of water accumulation caused by excessive local humidity around the humidifier.

[0006] A humidifier designed to prevent water accumulation includes a main unit, a mist-emitting fan, a diffusion fan, and an atomizer. The main unit contains an atomizing chamber and a diffusion duct chamber. The atomizing chamber and the diffusion duct chamber have a spray nozzle and a diffusion port respectively formed on the same side of the main unit, with the diffusion port surrounding the spray nozzle. The atomizer generates mist in the atomizing chamber. The mist-emitting fan blows air into the atomizing chamber, causing the mist to be blown out from the spray nozzle. The diffusion fan blows air into the diffusion duct chamber, and the air velocity blown out of the diffusion duct chamber through the diffusion port is greater than the air velocity blown out from the spray nozzle.

[0007] A humidifier designed to prevent water accumulation includes a main unit, a diffuser fan, and an atomizer. The main unit contains an atomizing chamber and a diffuser duct chamber. The atomizing chamber and the diffuser duct chamber have a spray nozzle and a diffuser outlet respectively formed on the same side of the main unit, with the diffuser outlet surrounding the spray nozzle. A connecting channel is provided between the diffuser duct chamber and the atomizing chamber. The diffuser fan blows air into the diffuser duct chamber, and the atomizer generates mist in the atomizing chamber. The air blown by the diffuser fan into the diffuser duct chamber is blown into the atomizing chamber through the connecting channel, causing the mist to be blown out from the spray nozzle. The wind speed blown out of the diffuser duct chamber through the diffuser outlet is greater than the wind speed blown out from the spray nozzle.

[0008] According to the water-proof humidifier of this application, in order to avoid water accumulation around the humidifier, a diffuser is provided around the spray nozzle of the humidifier. The high-speed airflow from the diffuser blows the mist sprayed from the spray nozzle higher, making the humidity diffuse faster. The annular diffuser can diffuse the mist that was originally blown from a single spray nozzle into an annular blowing direction, so that the mist can spread to a wider area around the humidifier, and will not cause the problem of excessive local humidity and water accumulation around the humidifier. Since the wind speed of the high-speed airflow from the diffuser is greater than the wind speed of the mist airflow from the spray nozzle, the high-speed airflow from the outside will accelerate the low-speed mist inside, making the mist blow higher and the diffusion area larger.

[0009] Furthermore, the main unit includes an atomizing housing and a diffusion duct housing. The atomizing chamber is formed within the atomizing housing, and the diffusion duct housing surrounds the atomizing housing, with the diffusion duct cavity formed between the atomizing housing and the diffusion duct housing. This arrangement of the diffusion duct housing and the atomizing housing makes it easier for the diffuser to blow out a high-speed airflow surrounding the spray nozzle.

[0010] Furthermore, the atomizing housing includes a mist outlet cover, an atomizing water tank, and an inner housing. The inner housing is installed in the atomizing water tank to form the atomizing chamber. The spray nozzle is located on the mist outlet cover. The inner housing has a mist outlet pipe that connects to the spray nozzle. The atomizer and the mist outlet fan are installed on the outer bottom surface of the atomizing water tank.

[0011] Furthermore, an extension extending out of the diffuser housing is provided on one side of the atomizing water tank, the extension being used to inject water into the atomizing water tank.

[0012] Furthermore, the atomizing housing also includes a motor mounting base, the diffuser fan includes a motor and a fan wheel, the motor mounting base is located at the bottom of the atomizing water tank, the motor is fixed on the motor mounting base, the output shaft of the motor passes downward through the motor mounting base and extends into the diffuser cavity, and the fan wheel is fixed on the output shaft in the diffuser cavity.

[0013] Furthermore, the mist-emitting fan is positioned between the atomizing water tank and the motor mounting base, and the motor mounting base has a first air inlet connected to the mist-emitting fan. Providing a first air inlet avoids interfering with the mist-emitting fan's ability to blow air into the atomizing chamber.

[0014] Furthermore, the spray nozzle and diffuser are located on the top surface of the main unit, and the bottom surface of the main unit is provided with a second air inlet, which is connected to both the mist outlet fan and the diffuser fan.

[0015] Furthermore, it also includes a water tank, on which the main unit is detachably mounted, and the water tank injects water into the atomizing chamber via a water pump.

[0016] Furthermore, a third air inlet is provided on the upper side of the water tank, which is connected to the second air inlet, and the lower end of the water tank is a water storage chamber. Attached Figure Description

[0023] The present invention relates to a humidifier that prevents water accumulation, as illustrated in the accompanying drawings.

[0024] like Figures 1 to 6The illustrated humidifier for preventing water accumulation includes a main unit 1, a mist-emitting fan 2, a diffuser fan 3, and an atomizer 4. The main unit 1 contains an atomizing chamber 11 and a diffuser duct chamber 12. The atomizing chamber 11 and the diffuser duct chamber 12 have a spray nozzle 111 and a diffuser 121 respectively formed on the same side of the main unit 1. The diffuser 121 surrounds the spray nozzle 111. This surround arrangement includes either a complete annular shape or an arc shape such as a semicircle or a quarter circle surrounding the spray nozzle 111. The atomizer 4 produces mist, and the mist-emitting fan 2 blows air into the atomizing chamber 11, causing the mist to exit through the spray nozzle 111. Traditional humidifiers, because they only have... The presence of a single spray nozzle 111 can lead to excessively high local humidity around the humidifier after prolonged operation, resulting in water accumulation in the surrounding environment. This application addresses this by using a diffuser fan 3 to blow air into the diffuser duct cavity 12. The airflow speed from the diffuser 121 is greater than that from the spray nozzle 111. The diffuser fan 3 is a larger, better, and higher-speed fan than the mist-emitting fan 2, thus enabling it to blow out a faster airflow speed from the diffuser 121. This allows the high-speed external airflow to further accelerate the low-speed internal mist, causing the mist to be blown higher. Furthermore, the annular diffuser 121 can diffuse the mist originally blown out by the single spray nozzle 111 into an annular blowing direction, allowing the mist to diffuse further around the humidifier.

[0025] like Figures 1 to 3 As shown, in order to better form a high-speed annular airflow blown out by the annular diffuser 121, the main unit 1 is provided with an atomizing shell 13 and a diffuser duct shell 14. The atomizing chamber 11 is formed in the atomizing shell 13, the diffuser duct shell 14 is arranged around the atomizing shell 13, and the diffuser duct cavity 12 is formed between the atomizing shell 13 and the diffuser duct shell 14. The arrangement of the diffuser duct shell 14 and the atomizing shell 13 makes it easier for the diffuser 121 to blow out a high-speed airflow surrounding the spray nozzle 111.

[0026] like Figure 1 and Figure 2As shown, the atomizing housing 13 includes a mist outlet cover 131, an atomizing water tank 132, and an inner housing 133. The atomizing water tank 132 is an upward-opening tank. The inner housing 133 is installed into the atomizing water tank 132 through the upper opening to form the atomizing chamber 11. The outer wall of the inner housing 133 presses against the inner wall of the atomizing water tank 132, so that the mist generated by the atomizer 4 can be gathered into the atomizing chamber 11. The spray nozzle 111 is provided on the mist outlet cover 131, and the inner housing 133 forms a mist outlet pipe 1331. The mist outlet pipe 1331 is connected to the spray nozzle 111. The atomizer 4 and the mist outlet fan 2 are installed on the outer bottom surface of the atomizing water tank 132. A through hole is provided on the bottom surface of the atomizing water tank 132. The transducer of the atomizer 4 is fixed at the through hole, so that the transducer can act on the water in the atomizing water tank 132 to generate water mist. The bottom surface of the atomizing water tank 132 is also provided with an air inlet pipe. The air outlet of the mist outlet fan 2 is opposite to the air inlet pipe. The outlet of the air inlet pipe is higher to prevent water from the atomizing water tank 132 from flowing back into the air inlet pipe.

[0027] like Figures 1 to 3 As shown in the figure, an extension 1321 extending out of the diffuser housing 14 is provided on one side of the atomizing water tank 132. The extension 1321 is used to fill water into the atomizing water tank 132. The extension 1321 makes it easier to fill water into the atomizing water tank 132, so that the user does not need to remove the mist outlet cover 131 and the inner housing 133 to fill water into the atomizing water tank 132. As shown in the figure, the diffuser housing 14 of this application is divided into an upper part 142 and a lower part 141. The upper part 142 is integrally formed with the atomizing water tank 132. The upper part 142 surrounds the main body of the atomizing water tank 132 in a C-shape. Both ends of part 142 are connected to extension 1321, and the upper part 142 and the outer side wall of the atomizing water tank 132 are connected by reinforcing rod 1421. The upper part 142 strengthens the overall structural strength of the atomizing water tank 132, making the atomizing water tank 132 less prone to deformation. After assembly, the upper part 142 and the lower part 141 will be joined together to form a diffuser duct shell 14. The lower part 141 is also provided with a notch 1411 for extension 1321 to extend out of the diffuser duct shell 14. The extension 1321 is provided with a water inlet 1322, through which water is injected into the atomizing water tank 132.

[0028] like Figures 1 to 3 As shown, the atomizing housing 13 also includes a motor mounting base 134, and the diffuser fan 3 includes a motor 31. The motor mounting base 134 is located at the bottom of the atomizing water tank 132, and the motor 31 is fixed on the motor mounting base 134. The diffuser fan 3 also includes a fan wheel 32. The output shaft 311 of the motor 31 passes downward through the motor mounting base 134 and extends into the diffuser duct cavity 12. The fan wheel 32 is fixed on the output shaft 311 in the diffuser duct cavity 12.

[0029] The mist-emitting fan 2 is disposed between the atomizing water tank 132 and the motor mounting base 134. The atomizing water tank 132 and the motor mounting base 134 can be fixedly connected by welding or other methods. The motor mounting base 134 can also serve as a mounting base for the mist-emitting fan 2. The mist-emitting fan 2 is fixed to the screw posts of the motor mounting base 134 by screws. The motor mounting base 134 is provided with a first air inlet 1342 that communicates with the mist-emitting fan 2. Figure 3 As shown, the motor mounting base 134 includes a groove and a limiting plate 1341. The motor 31 is installed in the groove. The limiting plate 1341 is fixed to the screw post on the inner side wall of the groove by screws. The output shaft 311 passes through the limiting plate 1341. In order to avoid affecting the air intake of the mist fan 2, the bottom surface of the groove is set as the first air inlet 1342. When the limiting plate 1341 is fixed, it will not completely close the groove. There is a gap for air intake between the limiting plate 1341 and the side wall of the groove.

[0030] like Figures 1 to 3 As shown, the spray nozzle 111 and diffuser 121 are disposed on the top surface of the main unit 1. The bottom surface of the main unit 1 is provided with a second air inlet 161, which communicates with the mist outlet fan 2 and the diffuser fan 3. The main unit 1 also includes a housing 15 and a bottom cover 16. The top surface of the housing 15 surrounds the mist outlet cover 131. The diffuser 121 is disposed on the top surface of the housing 15. The side surface of the housing 15 surrounds the diffuser duct housing 14. The extension 1321 extends into the housing 15. In the cavity between the diffuser housing 14 and the diffuser housing 15, the bottom cover 16 is fixed to the bottom opening of the outer housing 15. The second air inlet 161 is provided on the bottom cover 16. The lower end of the diffuser housing 14 is open and directly abuts against the bottom cover 16, so that the second air inlet 161 can be opposite to the air inlet of the impeller 32. Since there is still a gap between the impeller 32 and the motor mounting base 134, the second air inlet 161 can still be connected to the mist blower 2 through the first air inlet 1342.

[0031] like Figures 1 to 6As shown, it also includes a water tank 5. The main unit 1 is detachably installed on the water tank 5. The water tank 5 injects water into the atomizing chamber 11 through a water pump 53. The water pump 53 is located at the bottom of the water tank 5. The water pump 53 is connected to a water supply port 531 formed at the top of the water tank 5 through a pipe. The bottom cover 16 of the main unit 1 has a step 164 that cooperates with the side wall of the water tank 5, so that when the main unit 1 is installed on the water tank 5, the step 164 can abut against the side wall of the water tank 5. A water supply pipe 162 is on the bottom cover 16. The water supply pipe 162 is inserted downward into the water supply port 531 and connected upward through a water supply pipe 1323 to the water inlet 1322 of the extension 1321, so that the water pump 53 can pump water from the water tank 5 into the atomizing water tank 132. In addition, a power supply structure for supplying power from the main unit 1 to the water pump 53 is also formed between the installation structure of the main unit 1 and the water tank 5, such as Figure 5 and Figure 6 As shown, a power supply socket 163 and a power supply plug 532 are formed next to the water supply socket 531 and the water supply pipe 162, respectively. The power supply socket 163 and the power supply plug 532 work together to form a structure in which the main unit 1 supplies power to the water pump 53, so that the water tank 5 does not need to be equipped with an additional power supply line.

[0032] like Figures 1 to 6 As shown, the upper side of the water tank 5 is provided with a third air inlet 51, which is connected to the second air inlet 161, and the lower end of the water tank 5 is a water storage chamber 52.

[0033] Furthermore, the water-resistant humidifier of this invention can also omit the mist-emitting fan 2 and instead use a diffuser fan 3. A connecting channel is provided between the diffuser duct cavity 12 and the atomizing chamber 11. For example, a through hole is opened on the side wall or bottom wall of the atomizing housing 13, connecting the diffuser duct cavity 12 and the atomizing chamber 11. While the diffuser fan 3 blows air into the diffuser duct cavity, the air also blows into the atomizing chamber through the channel, causing the mist to be blown out from the spray nozzle and the diffuser port. For example, the diffuser fan introduces air into the main unit 1 through the impeller 32 via the third air inlet 51 on the water tank 5 and the second air inlet 161 on the bottom surface. The air entering the main unit 1 is blown out through the diffuser port 121 of the diffuser duct cavity 12, and simultaneously blown into the atomizing chamber 11 through the connecting channel between the diffuser duct cavity 12 and the atomizing chamber 11, causing the mist in the atomizing chamber 11 to be blown out from the spray nozzle 111. The resistance to airflow within the diffuser duct cavity 12 is lower than that within the atomizing cavity 11. Therefore, the airflow velocity from the diffuser port 121 of the diffuser duct cavity 12 is higher than that from the spray port 111 in the atomizing cavity 11. Consequently, the airflow from the diffuser port 121 accelerates the mist from the spray port 111, causing the mist to rise higher and diffuse further around the humidifier. Furthermore, to further ensure the acceleration effect, the connecting channel between the diffuser duct cavity 12 and the atomizing cavity 11 can be made with a smaller diameter, resulting in a lower airflow velocity entering the atomizing cavity. This increases the difference between the airflow velocity from the diffuser port 111 and the spray port 121, allowing the airflow from the diffuser port 111 to better accelerate the mist from the spray port 121, enabling the mist to diffuse further in all directions.

[0034] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model.
