Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, specifically to a desktop water-cooled fan. Background Technology

[0002] Small desktop water-cooled fans are popular among office workers and students due to their compact size. Traditional desktop water-cooled fans consist of a fan inside the casing, with a water evaporation carrier placed between the fan and the air outlet. This carrier draws in water from a tank to keep it moist. The fan draws air in through the air inlet, through the water evaporation carrier, where the water vaporizes to form cool, humid air, which is then blown out through the outlet. However, the water evaporation carrier obstructs airflow, affecting wind speed and noise, resulting in a poor user experience. To address this issue, some researchers have eliminated the water evaporation carrier and installed a small atomizing device in front of the fan. This device atomizes the water in the tank into a mist, which is then blown out by the airflow from the fan. While this solution solves the wind speed and noise problems, over time, the water mist accumulates on the desktop due to gravity, again negatively impacting the user experience. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a desktop water-cooled fan that features low noise and does not create water mist or condensation on the desktop, resulting in a superior user experience.

[0046] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0047] like Figures 1 to 3As shown, this utility model provides a desktop water-cooled fan, including a body assembly 1 and a water tank assembly 2. The water tank assembly 2 is located at the lower end of the body assembly 1. The body assembly 1 includes a housing 11, a water tank 17, a bracket 14, a fan assembly 16, and an evaporator 12 disposed within the housing 11. The housing 11 has an air outlet B on one side and an air inlet A on the other side. The bracket 14 is fixed to the air outlet B of the housing 11 and has an annular exhaust port 141 connected to the air outlet B. The annular exhaust port 141 is located near the edge of the bracket. The fan assembly 16 is fixed to the bracket 14. The air generated by the fan assembly 16 is discharged through the annular exhaust port 141 on the bracket 14. The evaporator carrier 12 is located at the air inlet A. The water tank 17 is located on the upper part of the casing 11. The water tank 17 has an open structure at the top, and its edge side forms a sealed connection with the inner side of the casing 11, so that there will be no air leakage. The drain port 173 of the water tank 17 corresponds to the upper end of the evaporator carrier 12. The lower end of the evaporator carrier 12 is connected to the water tank 21 of the water tank assembly 2, so that water can be directly added to the water tank 17 and the water in the water tank 17 can flow directly into the water tank 21 to realize the water filling of the water tank 21. The water tank 21 is equipped with a water pump 22 and a water injection pipe 25. The two ends of the water injection pipe 25 are connected to the outlet of the water pump 22 and the water injection port 172 of the water tank 17, respectively. When the water pump 22 is working, it directly transports the water in the water tank 21 to the water filling chamber 171 of the water tank 17 through the water injection pipe 25. The water in the water filling chamber 171 is then sprayed onto the evaporator 12 through the drain outlet 173, so that the evaporator 12 absorbs water and becomes moist. When the fan assembly 16 is working, it draws in air from the air inlet A of the casing 11, and the air passes through the moistened evaporator 12 to achieve cooling. Finally, the air is discharged from the air outlet B through the annular exhaust port 141.

[0048] As a further preferred embodiment of this utility model, a detachable top cover 3 is also provided at the upper end of the housing 11. The top cover 3 is fastened to the upper opening of the water tank 17, making it convenient to directly add water from the water tank 17. Alternatively, a water inlet can be opened on the top cover 3, so that water can be added to the water tank 17 without opening the top cover. The top cover 3 can also be fixed to the upper end of the housing 11, in which case the water tank 21 needs to be filled with water beforehand; or a water inlet (not shown in the figure) can be directly opened on the top cover 3, so that water can be added directly from the water inlet on the top cover 3 when adding water to the water tank 17, without opening the top cover 3 or removing the water tank 21, which is more convenient.

[0049] Meanwhile, this utility model also has a panel 18 fastened to the air outlet position, and an annular air outlet is formed at the edge of the panel 18, which is connected to the annular exhaust port 141. The setting of the annular exhaust port 141 significantly reduces exhaust noise, and at the same time, the air passing through the evaporator carrier 12 is used for cooling, so that no liquid droplets are mixed in the exhaust air, and no water mist or water accumulation is formed on the table.

[0050] like Figure 2 As shown, the fan assembly 16 includes a motor 161 and a diagonal flow fan blade 162. The diagonal flow fan blade 162 is connected to the shaft of the motor 161. The motor 161 is fixedly connected to the bracket 14 by screws. When the diagonal flow fan blade 162 is driven to rotate, it drives air to enter from the air inlet A and pass through the evaporator carrier 12. The cooled air is discharged from the annular exhaust port 141 of the bracket 14. The diagonal flow fan blade used in this invention significantly reduces the noise generated during operation and has a good quiet effect.

[0051] To further enhance the user experience, a duct 163 is provided in the fan assembly 16. One end of the duct is fixedly connected to the bracket 14. The oblique flow fan blade 162 is placed in the duct 163. Preferably, the duct 163 adopts a conical structure, with its large end fixedly connected to the bracket 14 and its small end close to the air inlet A. The air inlet A, the duct 163, and the oblique flow fan blade 162 are coaxially arranged. The cooled airflow entering the duct 163 is directly discharged from the annular exhaust port 141. Of course, other shapes of ducts can also be used, such as those with a rectangular cross-section.

[0052] As a further preferred embodiment of this utility model, such as Figure 2 and Figure 4 As shown, a water receiving box 15 is also installed at the lower part of the casing 11. The water receiving box 15 is detachably and fixedly connected to the water tank 21. The water receiving box 15 is provided with a water receiving trough 151 and a water return port 152. The lower part of the evaporator 12 is inserted into the water receiving trough 151. The water return port 152 is located at the bottom of the water receiving trough 151 and is connected to the water tank 21. Excess water flows from the evaporator 12 into the water tank 21 through the water return port 152.

[0053] In this utility model, the water receiving box 15 and the water tank 21 are detachably and fixedly connected by a snap-fit ​​connection structure. The specific structure is as follows: Figure 2 and Figure 5As shown, snap holes 153 are provided at both ends of the water receiving box 15. When the body assembly 1 is installed on the water tank 21, horizontal elongated holes 211 corresponding to the positions of the snap holes 153 are provided at both ends of the water tank 21. A push button 23 and a latch 24 are installed at the elongated holes 211. The push button 23 and the latch 24 are fixedly connected at the elongated holes 211 by screws or direct fastening. Since the length of the elongated hole 211 is greater than the length of the push button 23, the push button 23 is manually pushed to move along the elongated hole 21. 1. The locking buckle 24 is also provided with a protruding bone 241 extending into the water tank 21. When the push button 23 is manually pushed to move back and forth along the elongated hole 211, the protruding bone 241 is disengaged or engaged in the buckle hole 153. When the protruding bone 241 is disengaged from the buckle hole 153, the body assembly 1 can be removed from the water tank 21 for cleaning. When the protruding bone 241 is engaged in the buckle hole 153, the water receiving box 15 is connected to the water tank 21.

[0054] As a further preferred embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the casing 11 includes a front casing 111 and a rear casing 112 that are snap-fitted together. An air inlet A is provided on the rear casing 112, and a recess 1121 is formed at the air inlet A. The bottom plate of the recess 1121 is grid-shaped, allowing external air to enter the inner cavity of the casing. An evaporator 12 is installed in the recess 1121, with its lower end penetrating through the recess 1121 and interlocking with the water collection tank 151. A dustproof net 13 is installed on the outside of the evaporator 12. When the oblique flow fan blades rotate, external air passes through the dustproof net, the evaporator, and the grid-shaped bottom plate of the recess in sequence, forming cooled and humidified air, which then enters the annular exhaust port through the air duct 163 and is discharged.

[0055] The specific steps are as follows:

[0056] Open the top cover and add an appropriate amount of water to the water tank above the machine. The water will drip onto the evaporator from the drain outlet and then flow into the water tank from the return outlet of the water collection box.

[0057] When the start switch is turned on, the motor drives the diagonal-flow fan blades to rotate, drawing air in through the air inlet and through the evaporator. Simultaneously, the water pump pumps water from the tank into the water filling tank, which then sprays water onto the evaporator through the drain outlet to keep it moist. As the air passes through the evaporator, it vaporizes the water on the evaporator, absorbing heat from the air and lowering its temperature. The evaporated water is then blown out through the air duct and the annular air outlet. Any unevaporated water flows back to the tank for reuse.

[0058] When the water tank needs cleaning, push the push button, the protruding bone on the latch will disengage from the buckle hole of the water box, lift the body part, and remove the water tank for easy independent cleaning.

[0059] Any aspects not covered in this utility model are applicable to the prior art.

[0060] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
