Description

Technical Field

[0001] This utility model relates to a fan, and more particularly to an integrated desktop humidifying fan that can be placed on an office desk, study desk, or bedside table. Background Technology

[0002] Desktop fans are common small household appliances primarily used to provide localized air circulation and cooling. Their basic structure typically includes fan blades, a motor, a fan guard, and a support base; some fans also come with a control switch to adjust the fan speed. Desktop fans are mainly used for airflow regulation in personal spaces, and are particularly suitable for small areas such as desktops and bedside tables.

[0003] Patent CN 212006074U discloses a desktop humidifying fan that combines the functions of a fan and a humidifier, offering two usage modes: a humidifying fan and an air-circulating humidifier. The fan assembly includes a front exhaust grille, a rear intake grille, and fan blades. The humidifier assembly includes a top cover and a base, with a water storage tank inside the base. Through rear-intake humidification, the humidifier delivers moisture into the air, which is then dispersed and blown out by the fan, achieving uniform humidification and cooling. Furthermore, it features an ultrasonic atomizing plate as a spray component, and a structural design that facilitates water filling and waterproofing. The overall structure is compact, making it suitable for desktop use in offices and residences.

[0004] Patent CN 213775757U discloses a liftable humidifying fan, comprising a fan mechanism, a lifting mechanism, and a humidifying mechanism. The lifting mechanism, connected to the fan mechanism, consists of a motor, a screw, and a lifting accessory. The motor drives the screw to rotate, allowing the lifting accessory to move up and down along the screw, thus enabling the fan to be stored. When not in use, the fan can be retracted into its casing, maintaining an aesthetically pleasing appearance. The fan also features a push-button switch and a toggle switch, allowing for separate control of the spray and fan functions, enabling independent operation of the airflow and humidification functions and enhancing practicality.

[0005] Problems with existing split-type desktop humidifiers: 1. Split-type desktop humidifiers typically consist of a separate fan and a humidifier, both of which need to be placed separately on the desktop. This takes up valuable desktop space in limited office or living environments, making them appear cumbersome. 2. The split structure makes the overall product appearance somewhat fragmented, lacking the coordination and aesthetics of an integrated design. It is difficult to meet users' high aesthetic demands for product appearance, especially in places where decorative effects are important, where split-type humidifiers may appear out of place. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide an integrated desktop humidifier fan with a compact structure and easy assembly.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is: an integrated desktop humidifier fan, comprising:

[0008] Base;

[0009] The fan body is mounted on the base;

[0010] The fan body includes a housing, a mounting frame, a water tank, a fan assembly, an air duct ring, and an atomizer;

[0011] The mounting frame is disposed inside the housing;

[0012] The water tank is located in the middle of the mounting frame;

[0013] The mounting frame is provided with an annular air outlet surrounding the water tank;

[0014] The fan assembly and the duct ring are fixed to the rear side of the mounting frame. The duct ring is located on the periphery of the fan assembly and is used to guide the airflow entering from the rear to the annular air outlet.

[0015] The atomizer is mounted on the water tank, and the mist it generates is configured to mix with the airflow at the annular air outlet.

[0016] An air inlet is provided on the outer casing at the position corresponding to the fan assembly;

[0017] The water tank is equipped with a water inlet.

[0018] A further preferred embodiment of this utility model is that the fan assembly includes a motor and fan blades driven by the motor.

[0019] A further preferred embodiment of this invention is that the fan body is connected to the base via a hinge mechanism to achieve adjustment of the tilt angle.

[0020] A further preferred embodiment of this utility model is that the water inlet of the water tank is equipped with an openable and closable plug.

[0021] A further preferred embodiment of this utility model is: the atomizing generator includes:

[0022] An absorbent cotton swab, the rear end of which extends into the water tank;

[0023] An atomizing plate is disposed at the front end of the absorbent cotton swab;

[0024] A pressure plate is used to press the atomizing sheet onto the absorbent cotton rod. The pressure plate has an opening for the mist to pass through.

[0025] A further preferred embodiment of this utility model is that a battery module is provided inside the base, and an operation panel for controlling the fan and humidification functions is provided on the surface of the base.

[0026] A further preferred embodiment of this invention is that the fan body is rotatably mounted on the base to achieve tilt adjustment of the airflow direction.

[0027] A further preferred embodiment of this utility model is that the top of the outer shell is provided with a water inlet that communicates with the water tank.

[0028] A further preferred embodiment of this utility model is that the operation panel integrates a timer control unit for setting the automatic shutdown time of the fan and / or humidification function.

[0029] Compared with the prior art, the advantages of this utility model are: 1. By setting the water tank in the middle of the installation frame and using the surrounding annular air outlet and air duct ring to construct a unified air supply path, the humidification and fan functions are successfully integrated into a compact unit, solving the problem that the traditional solution requires two devices and occupies too much desktop space, and realizing structural integration.

[0030] 2. Because the mist generated by the atomizer is directly mixed with the airflow at the annular air outlet, the mist is fully carried away and diffused throughout the space by a strong and uniform airflow the moment it leaves the device. This "instant mixing" mechanism fundamentally overcomes the technical biases of uneven mist diffusion in traditional humidifiers and insufficient mixing leading to condensation along the way in traditional fan humidifiers, providing a humid and uniform comfortable airflow.

[0031] 3. Through the integrated air duct design of "rear air intake - air duct ring guide - ring air outlet", the airflow is smooth and the resistance is small. This not only improves the air delivery efficiency and distance, but also effectively reduces the working noise of the fan and achieves quiet operation.

[0032] 4. By setting up an independent mounting frame as the core load-bearing structure, the main components such as the water tank, fan assembly, and air duct ring are modularly integrated onto it, greatly facilitating product assembly and production. At the same time, this clear structural division also facilitates subsequent cleaning, maintenance, and component replacement. Attached Figure Description

[0046] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0047] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it will not be further defined and explained in subsequent figures.

[0048] like Figures 1 to 4 As shown, this embodiment provides an integrated desktop humidifier fan 100, including a base 10 and a fan body 20 mounted on the base 10.

[0049] The base 10 supports the fan body 20, and a battery module 12 is installed inside the base to provide power to the entire unit. An operation panel 13 is located on the surface of the base, used to control the fan and humidification functions, including starting and stopping, adjusting the fan speed, and setting a timer to turn off.

[0050] The control panel 13 integrates a timer control unit, allowing users to preset the automatic shutdown time of the fan and / or humidification functions as needed.

[0051] The base 10 and the fan body 20 are connected by a hinge mechanism. Users can adjust the tilt angle of the fan body 20 relative to the base 10 through the hinge mechanism to change the airflow direction.

[0052] The fan body 20 includes: a housing 21, a mounting frame 22, a water tank 23, a fan assembly 24, an air duct ring 25, and an atomizer 26.

[0053] The outer casing 21 forms the external protective structure of the fan body, and an air inlet 211 is provided at the rear to allow air to enter the fan body. The top of the outer casing 21 has a water inlet v that communicates with the water tank 23, allowing users to directly add water to the tank, making it convenient to use.

[0054] In addition, the mounting frame 22 is located inside the outer shell 21 and is the core structure that supports the fan assembly 24, water tank 23, air duct ring 25 and atomizer 26.

[0055] A water tank 23 is installed in the middle of the mounting frame 22, and an annular air outlet 221 is formed around it. The airflow delivered by the fan is guided by the air duct ring 25 and then blown out evenly from the annular air outlet 221.

[0056] The water tank 23 is located in the middle of the mounting frame 22 and is used to store the water required for humidification. The upper part of the water tank 23 is provided with a water inlet 231, and an openable and closable plug 27 is installed at the water inlet 231 to prevent water leakage and dust from entering.

[0057] It should be noted that the fan assembly 24 and the duct ring 25 are mounted on the rear side of the mounting frame 22, and include a motor 241 and a fan blade 242 driven by the motor.

[0058] When the motor 241 is running, it drives the fan blades 242 to rotate, drawing in air through the air inlet 211 of the housing 21. The air flows through the air duct ring 25, which is used to evenly guide the airflow entering from the rear to the annular air outlet 221, achieving a stable and gentle airflow effect.

[0059] Further details are needed regarding the atomizer 26, which is mounted on the water tank 23, and its structure is as follows: Figure 5 , Figure 10 , Figure 11 , Figure 12As shown, it includes: a water-absorbing cotton swab 261: the rear end of which extends into the water tank 23, and the front end which is connected to the atomizing plate 262, for absorbing water.

[0060] Atomizing plate 262 is located at the front end of absorbent cotton swab 261. When energized, it generates ultrasonic vibrations, atomizing water molecules into fine water mist. Pressure plate 263 presses and fixes atomizing plate 262 firmly onto absorbent cotton swab 261 to prevent loosening. Opening 264 is provided on pressure plate 263 to allow the mist to pass smoothly and mix with the airflow in the duct.

[0061] The mist generated by the atomizer 26 is discharged through the opening 264 of the pressure plate 263 and directly enters the annular air outlet 221, where it mixes instantly with the airflow delivered by the fan assembly 24 at the outlet, forming a humid and comfortable air delivery effect.

[0062] Preferably, such as Figure 6 , Figure 11 , Figure 12 As shown, a water tank cover 233 can be installed at the front end of the water tank 23. A connecting post is provided on its outer surface. The connecting post passes through the corresponding connecting hole on the connecting plate 267 to achieve a fixed connection.

[0063] The outer surface of the connecting plate 267 is provided with a snap-fit ​​hole, which cooperates with the snap-fit ​​part on the inner wall of the pressure plate 263 to make the pressure plate 263 securely connected to the outside.

[0064] The connecting plate 267 has a clearance hole in the center to ensure that the mist can be discharged smoothly.

[0065] This structure is easy to disassemble and clean, and the exterior part of the pressure plate 263 can also serve as a decorative part, enhancing the overall aesthetics.

[0066] A decorative annular plate r can be installed in the outer annular area of ​​the annular air outlet 221, which not only serves an aesthetic purpose but also improves airflow guidance.

[0067] When the user turns on the fan function, the motor 241 drives the fan blades 242 to rotate, and air is drawn in through the air inlet 211, passes through the air duct ring 25, and is blown out evenly through the annular air outlet 221.

[0068] When the humidification function is turned on, the mist generated by the atomizing plate 262 is discharged along the opening 264 and immediately mixed with the airflow of the fan at the annular air outlet 221. It is then quickly carried out by the airflow to form a fine, moist and evenly distributed mist airflow.

[0069] Throughout the process, water tank 23 provides a continuous water supply, and the water level sensor monitors the water volume in real time and provides an indication via a water level indicator light. The control panel 13 allows for independent or coordinated control of humidification, air supply, and timer functions.

[0070] In summary, this embodiment integrates the fan assembly 24, water tank 23, and atomizing module within the same mounting frame 22, reducing assembly steps and connection interfaces, significantly improving product stability and sealing, and avoiding the problems of water mist backflow and loose connections in traditional split designs. Integrating the water tank 23, fan assembly 24, and atomizing device within the mounting frame creates an integrated airflow path for simultaneous airflow and mist output, achieving a close integration of humidification and air delivery functions. This not only enhances the product's functionality and practicality but also optimizes its overall appearance and user experience.

[0071] The atomized airflow mixes synchronously with the main airflow at the annular air outlet and is then output, making the water mist particles more evenly distributed and able to quickly diffuse into the air, improving humidification efficiency and avoiding localized dampness.

[0072] The ring-shaped air duct design creates a closed-loop airflow, resulting in smoother airflow, reduced turbulence and noise, and improved quiet operation, making it suitable for use in bedrooms, offices, and other environments.

[0073] Furthermore, the pressure plate 263, connecting plate 267, and decorative ring r form an independent module, which is convenient to assemble and improves production efficiency. Moreover, through the cooperation of the water level sensor and the timer control unit, it can automatically prompt or shut down the operation when the water level is insufficient or the timer expires, preventing dry burning and circuit damage, making it safer and more reliable to use.
