An ultrasonic spray device

Abstract

This utility model discloses an ultrasonic spraying device, including a barrel, an ultrasonic atomizer, a cover, and a fan. The barrel has an atomization chamber and a first cylinder for water inlet, with a water outlet at the bottom communicating with the atomization chamber. The ultrasonic atomizer is installed inside the atomization chamber and atomizes the water entering the chamber. The first cylinder also has a water level regulator to maintain the required liquid level for the ultrasonic atomizer. The fan supplies air to the atomization chamber and drives airflow within the chamber, causing the mist and water to separate vertically. The mist is then sprayed out through the nozzle under the airflow within the atomization chamber. Thus, the mist flows within the atomization chamber, and larger droplets or droplets with high water content tend to settle naturally during the flow, preventing them from being directly carried out of the nozzle, improving the dryness and uniformity of the output mist. Simultaneously, the water level regulator continuously maintains the required liquid level for the ultrasonic atomizer, enhancing the continuous stability of atomization.

[0002] In existing air conditioning fans, air conditioners, and other devices with water mist humidification functions, ultrasonic atomizing devices are often used to atomize water to achieve the humidification effect.

[0003] However, this type of spraying device still has shortcomings in practical applications: On the one hand, ultrasonic atomizers are usually placed directly near the nozzle or installed in locations with limited structural space, resulting in a large amount of liquid water being carried in the mist produced by atomization, affecting the uniformity of spraying, and excessive water can easily form water accumulation at the equipment outlet or cause the surrounding area to be damp; on the other hand, the spraying device also lacks an automatic water replenishment and control mechanism to maintain a suitable liquid level in the ultrasonic atomizer; when the water level is lower than the height required for atomization, the device cannot continue to spray normally, and users need to manually replenish water in time, which is cumbersome and affects the continuous use experience, especially in nighttime or unattended scenarios.

[0014] The top of the cover is also provided with a wire hole so that the wire of the ultrasonic atomizer can be led out through the wire hole.

[0015] Furthermore, a noise-reducing and splash-proof cone is provided inside the first cylinder at the position corresponding to the water inlet hole. The noise-reducing and splash-proof cone is used to reduce the noise generated when liquid falls from the water inlet hole.

[0019] Furthermore, the fan mounting bracket is provided with a first through hole communicating with the air inlet end of the fan;

[0020] The fan mounting bracket is provided with connecting ears on both sides, and a second through hole is provided on the connecting ears.

[0021] Furthermore, it also includes a connecting pipe, and the cover is provided with an air outlet pipe communicating with the atomizing chamber. One end of the connecting pipe is connected to the air outlet pipe, and the other end is connected to the nozzle.

[0022] Furthermore, it also includes a base, one side of which is provided with a positioning plate, and the top of the positioning plate is provided with a fastener;

[0026] In summary, this utility model has the following technical effects:

[0027] 1. The ultrasonic spraying device of this utility model, by setting up an independent and relatively large atomizing chamber, allows the mist to form a sufficient spatial flow inside the atomizing chamber. The larger droplets or droplets with high water content are more likely to settle naturally during the flow, avoiding being carried directly out of the nozzle. This makes the discharged mist more delicate and gentle, improves the dryness and uniformity of the output mist, and also avoids water accumulation at the equipment outlet or causing the surrounding area to be damp. This helps to ensure the long-term stable operation of the equipment and the safety of users.

[0028] 2. The ultrasonic spray device of this utility model forms an independent water inlet path and mist flow path by the cover abutting against the top of the first cylinder, thereby effectively separating the water inlet area and the mist area in terms of structure. At the same time, when water enters the first cylinder through the water inlet hole, it enters the atomization chamber through the water outlet at the bottom of the first cylinder, thereby forming an independent water inlet channel. In addition, the first cylinder is provided with an overflow drainage hole to maintain the liquid level required by the ultrasonic atomizer, so that the water level in the first cylinder and the water level in the atomization chamber are always consistent, avoiding the water level being too high or too low, which would affect the atomization effect of the ultrasonic atomizer, effectively extending the service life of the ultrasonic atomizer and improving the atomization stability.

[0029] 3. This utility model of ultrasonic spray device simplifies the assembly process of ultrasonic atomizers by setting an installation groove in the atomization chamber, allowing the ultrasonic atomizer to be installed in the groove via a snap-fit ​​method. This avoids the use of complex fixing structures such as screws, facilitating quick installation of the ultrasonic atomizer and improving the convenience of subsequent disassembly, replacement, or maintenance. Furthermore, users only need to open the cover to directly access the interior of the atomization chamber, enabling quick disassembly and assembly of the ultrasonic atomizer without the need for additional tools, further reducing maintenance difficulty, extending the overall service life of the equipment, and enhancing the user experience.

[0042] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0043] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0045] like Figure 1-10An ultrasonic spraying device is shown, comprising a barrel 1, an ultrasonic atomizer 2, a cover 3, and a fan 5. The barrel 1 has an atomizing chamber 11 and a first cylinder 13 for water inlet. The bottom of the first cylinder 13 has a water outlet 131 communicating with the atomizing chamber 11, facilitating the guidance of water from the first cylinder 13 into the atomizing chamber 11. The ultrasonic atomizer 2 is installed in the atomizing chamber 11 and is used to ultrasonically atomize the water entering the atomizing chamber 11 to form a fine and uniform water mist. The first cylinder 13 also has a water level regulator to maintain a stable liquid level required by the ultrasonic atomizer 2, thereby ensuring that the ultrasonic atomizer 2 operates continuously under optimal working conditions, improving spraying efficiency and device operation. Reliability; The cover 3 has a water inlet 31 that communicates with the first cylinder 13. The cover 3 is placed on the top of the barrel 1 and is connected to the top of the first cylinder 13. A nozzle 8 for outputting mist is connected to the top of the cover 3. The fan 5 is used to supply air to the atomizing chamber 11 and drive the air flow in the atomizing chamber 11. During the flow of mist, droplets with larger particle size or higher water content are easy to settle naturally and achieve separation. Thus, the floating fine and uniform mist is output through the nozzle 8 under the action of air flow in the atomizing chamber 11, thereby improving the uniformity and quality of spraying. At the same time, it avoids water accumulation at the equipment outlet or causing the surrounding area to be damp, which is conducive to ensuring the long-term stable operation of the equipment and the safety of users.

[0046] See Figure 2-3 The bottom of the cover 3 is provided with an insert 37 that mates with the first cylinder 13. The insert 37 is inserted into the top of the first cylinder 13 to form a stable insertion structure. The water level regulating component is an overflow drain hole 14 for preventing excess water from overflowing, so that the water level in the first cylinder 13 enters the atomizing chamber 11 through the water outlet 131 and remains consistent, thereby maintaining a suitable working liquid level for the ultrasonic atomizer 2 and ensuring that the liquid level in the atomizing chamber 11 is always at the effective working height of the ultrasonic atomizer 2 (e.g., Figure 3 The water level and water flow direction shown in the figure prevent the atomization efficiency from decreasing due to water shortage or excessively high liquid level, effectively improving the reliability and continuous working capability of the spraying device.

[0047] It should be noted that during use, one end of the connecting water pipe can be connected to the bottom of the overflow drain hole 14, and the other end can be connected to the water inlet pipe 9 or directly to the second cylinder 32. Excess water entering the cylinder 1 through the water inlet hole 31 will automatically overflow through the overflow drain hole 14 in the first cylinder 13, and then flow back into the first cylinder 13 through the connecting water pipe, achieving continuous water circulation and replenishment. This structure not only continuously provides water to the first cylinder 13 during use, preventing low water levels from affecting the atomization effect, but also, relying on the limiting height of the overflow drain hole 14, maintains the working liquid level of the ultrasonic atomizer 2 within a suitable range, effectively ensuring the stable and continuous operation of the atomizing device, improving the overall automation level of the equipment and user convenience, and reducing the inconvenience caused by frequent water addition.

[0048] In addition, such as Figure 9-10 As shown in the application, a water storage tank 91 or a water storage bucket can be installed at the top of the water inlet pipe 9 to meet the atomization requirements. The other end of the water pipe can be connected to the water storage tank 91 or the water storage bucket. The overflow from the overflow drain hole 14 flows back into the water storage tank 91 or the water storage bucket, and then flows into the bucket body 1 through the water inlet pipe 9 to achieve continuous circulation. The overflow backflow can be achieved by setting a water pump or other structures.

[0049] Furthermore, to facilitate convenient disassembly and maintenance, the atomizing chamber 11 is provided with an installation slot 12. The ultrasonic atomizer 2 can be fixed in the installation slot 12 by snap-fit, without the need for screws or other additional fasteners. Users only need to open the cover 3 to access the ultrasonic atomizer 2, which enables quick removal and replacement of the ultrasonic atomizer 2, simplifies the maintenance process, and improves the ease of operation for users. The top of the cover 3 is also provided with a wire hole 36 for leading out the wire of the ultrasonic atomizer 2, ensuring safe and stable electrical connection.

[0050] In addition, a wire hole 36 is provided on the top of the cover 3 to lead the wire of the ultrasonic atomizer 2 out of the barrel 1, which effectively avoids the problem of wire tangling or damage. At the same time, it also allows the ultrasonic atomizer 2 to be disassembled without cutting or disassembling the wire connection, further improving the maintainability and safety of the structure, and enhancing the serviceability of the device in long-term operation and the user's operating experience.

[0051] In this embodiment, in order to reduce the noise generated by the liquid falling in during the water inlet process, a sound-absorbing and splash-proof cone 15 is provided in the first cylinder 13 at the position corresponding to the water inlet hole 31, which can effectively suppress the water flow impact noise and splashing problem, and improve the product's quiet performance and user experience.

[0052] See Figure 7The device also includes a second cylinder 32 located on top of the cover 3. The second cylinder 32 has an opening at the top, through which water is added via a water inlet pipe 9. The bottom of the second cylinder 32 has a water inlet hole 31, and a filter sponge 6 is installed inside to perform preliminary filtration of the added water, preventing impurities from entering the atomization chamber 11 through the first cylinder 13, thereby improving the atomization cleanliness and spray quality of the system, while protecting the stable operation of the ultrasonic atomizer 2.

[0053] Furthermore, to facilitate the fixing of the fan 5 and the realization of its air supply function, the device also includes a fan fixing bracket 51 for reliably installing the fan 5 on the top of the cover 3. The cover 3 is provided with an air inlet 331 communicating with the atomizing chamber 11. The air inlet end of the fan 5 is engaged in the slot 33 and fixed to the cover 3 by the fan fixing bracket 51. When the fan 5 rotates, air can be supplied to the atomizing chamber 11 through the air inlet 331, driving the air in the atomizing chamber 11 to circulate. This allows larger droplets or droplets with higher water content to easily settle and separate during the flow of the mist. The floating, fine, and uniform mist is output through the nozzle 8 under the action of the air flow in the atomizing chamber 11.

[0054] Specifically, the fan mounting bracket 51 has a first through hole 52 communicating with the air inlet of the fan 5, and connecting ears 53 on both sides. The connecting ears 53 have second through holes, and the top of the cover 3 has a connecting post 34 corresponding to the position of the connecting ears 53. The fan mounting bracket 51 is sleeved on the outside of the fan 5 and locked to the connecting post 34 by the first fastener passing through the second through hole, ensuring that the fan 5 is securely installed and runs smoothly, and improving the structural strength of the device and the reliability of component installation.

[0055] See Figure 4 The device also includes a connecting pipe 7. The cover 3 is provided with an air outlet pipe 35 that communicates with the atomizing chamber 11. One end of the connecting pipe 7 is connected to the air outlet pipe 35, and the other end is connected to the nozzle 8. The fan 5 blows air into the atomizing chamber 11, which drives the air in the atomizing chamber 11 to circulate. During the flow of the mist, the larger droplets or the mist droplets with high water content are easy to settle naturally and achieve separation. The floating fine and uniform mist passes through the air outlet pipe 35 under the action of the air flow in the atomizing chamber 11 and is guided to the outlet of the nozzle 8 for output through the connecting pipe 7. This realizes the controllable and directional discharge of the mist output from the atomizing chamber 11, thereby improving the spraying efficiency.

[0056] See Figure 8 The device also includes a base 4, with a positioning plate 41 on one side and a fastener 42 on the top of the positioning plate 41. When the bucket 1 is installed on the base 4, one side of it abuts against the positioning plate 41, and the fastener 42 is fastened to the top of the cover 3, which can realize the quick positioning and fixing of the bucket 1 and the base 4, effectively enhancing the stability of the overall structure and preventing shaking or falling off due to vibration or movement during use.

[0057] See Figure 5-6 The barrel body 1 has first connecting plates 16 on both sides, and the first connecting plates 16 have grooves 17 for fasteners to pass through. The positioning plate 41 has second connecting plates 43 on both sides, and the second connecting plates 43 have mounting holes 44 corresponding to the grooves 17. When the barrel body 1 is in contact with the positioning plate 41, the first connecting plates 16 and the second connecting plates 43 abut against each other, and the second fasteners pass through the grooves 17 and are locked in the mounting holes 44, thereby further improving the connection strength and ensuring that the barrel body 1 and the base 4 are firmly fixed.

[0058] It should be noted that the bottom of the barrel 1 is provided with a locking block 18, and the base 4 is provided with a locking groove 45 corresponding to the locking block 18. When the barrel 1 is installed in close contact with the positioning plate 41, the locking block 18 can be accurately embedded in the locking groove 45, so as to effectively limit and securely fix the barrel 1, further improve the structural stability of the equipment during operation, and prevent the assembly from loosening due to vibration or displacement.

[0059] Furthermore, the second fastener features a detachable structure, allowing users to loosen or remove it as needed. This enables quick assembly and disassembly between the barrel 1 and the base 4, facilitating daily cleaning and maintenance and enhancing usability. In other embodiments, a rotating block can be provided on the second fastener, allowing users to tighten or loosen it manually, eliminating the need for specialized tools and further improving the efficiency and ease of assembly and disassembly of the barrel 1 and base 4, thus adapting to the maintenance needs of more household or portable applications.

[0060] In summary, the ultrasonic spraying device of this invention, by setting up an independent and relatively large atomizing chamber 11, allows the mist to form a sufficient spatial flow inside the atomizing chamber 11. The larger droplets or droplets with high water content are more likely to settle naturally during the flow, avoiding being directly carried out of the nozzle 8. This results in a finer and softer mist, improving the dryness and uniformity of the output mist. It also prevents water accumulation at the equipment outlet or causes dampness in the surrounding area, which helps ensure the long-term stable operation of the equipment and the safety of users.

[0061] This novel ultrasonic spray device, through the abutment of the cover 3 against the top of the first cylinder 13, forms an independent water inlet path and mist flow path, thereby effectively separating the water inlet area and the mist area structurally. Simultaneously, when water enters the first cylinder 13 through the water inlet 31, it enters the atomization chamber 11 through the water outlet 131 at the bottom of the first cylinder 13, thus forming an independent water inlet channel. Furthermore, the first cylinder 13 is equipped with an overflow drain hole 14 to maintain the required liquid level for the ultrasonic atomizer 2, ensuring that the water level inside the first cylinder 13 remains consistent with the water level inside the atomization chamber 11. This prevents the water level from being too high or too low, thus avoiding impact on the atomization effect of the ultrasonic atomizer 2, effectively extending the service life of the ultrasonic atomizer 2, and improving atomization stability.

[0062] This utility model of ultrasonic spray device simplifies the assembly process of ultrasonic atomizer 2 by setting an installation groove 12 in the atomization chamber 11 and installing the ultrasonic atomizer 2 in the installation groove 12 by snap-fit. It avoids the use of complex fixing structures such as screws, which facilitates the quick installation of ultrasonic atomizer 2 and also improves the convenience of its later disassembly, replacement or maintenance. Moreover, the user only needs to open the cover 3 to directly access the inside of the atomization chamber 11, so as to realize the quick disassembly and assembly of ultrasonic atomizer 2 without the need for additional tools, further reducing the difficulty of maintenance, helping to extend the overall service life of the equipment and improve the user experience.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
