detailed description

The preferred embodiments of the present invention are described in the following, and the preferred embodiments described herein are intended to illustrate and explain the invention.

Embodiments of the present invention provide a cooling fan including a water tank, a water adding device, an ice crystal box, an ice box, and other structures.

As shown in Fig. 1, a water adding device 1 is provided on the lower middle portion of the cooling fan, that is, on the side wall of the portion of the water tank. Water can be directly added to the cooling fan water tank by the water adding device 1, or the hand can be put in or removed by the water adding device 1. Ice crystal box. The water adding device 1 is configured as a rotatable open structure. As shown in FIG. 5, when the water adding device 1 is opened, water can be added to the water tank of the cooling fan through the water adding device 1, or the ice crystal box can be taken out or placed by the water adding device 1 into the water tank. As shown in Figures 3 and 4, when the watering device 1 is closed, at least a portion of the watering device 1 constitutes a portion of the side wall of the cooling fan, thereby forming an enclosed space of the water tank when closed. As shown, the watering device 1 is preferably of a tapered configuration, such as a funnel-shaped structure having a larger upper end opening 11 and a smaller lower end opening 12. In the present embodiment, the water adding device 1 further has a side opening 13. Among them, the upper end opening 11, the side opening 13 and the lower end opening 12 are actually formed as an integral opening suitable for a person to take out the ice crystal box 2 from the ice box 3 or place the ice crystal box 2 in the ice box 3. Therefore, when it is necessary to take out or place the ice crystal box, it is not necessary to open the filter 4 and the evaporating filter 5 shown in Fig. 2.

At least a portion of the water adding means constituting a part of the side wall of the cooling fan is a square member. Preferably, the square member is a square plate that fits the opening of the side wall of the tank. In a preferred structure of the watering device 1 such as a funnel-shaped structure, the square plates are opposite to the side openings 13, and the ends of the square plates forming the end of the ice crystal box are respectively connected to the side plates, between the two side plates and the square plates. An opening is formed to fit the entire hand of the ice crystal box from the ice box. In an embodiment of the funnel-shaped structure, the two side panels may be sector-shaped side panels. A roller is provided in the lower portion of the water adding device 1, i.e., near the lower end opening 12, for rotatably connecting the water adding device 1 to the side wall of the cooling fan and enabling the water adding device 1 to be rotated open or closed as needed. The roller is preferably arranged to protrude outwardly through the two sector-shaped side plates, and the outwardly projecting portion is rotatably disposed on the side wall of the cooling fan. As shown in Figs. 4 and 8, a water adding device holder 6 is provided on the side wall of the cooling fan, and an outwardly projecting portion of the roller is mounted on the water adding device holder 6. As shown in Fig. 9, two grooves are respectively provided on the left and right sides of the lower portion of the water adding device holder 6, and the roll axially outward convex portion is rotatably installed in the groove.

A buckle is also provided on the water adding device 1. Specifically, the buckle is disposed outside the square plate, and is recessed inward to form a structure for the human hand to enter and outwardly pull the square plate. The user can open the watering device by pressing the hand. A snap structure for engaging with the water supply device bracket on the side wall of the cooling fan is further disposed on the upper portion of the water adding device 1, and the water adding device is pushed toward the water tank to be fastened to the side wall of the cooling fan.

As shown in FIG. 3 to FIG. 5, the ice crystal box 2 is placed in the ice box frame 3 when it is used, and the ice box frame 3 is obliquely disposed at a certain angle in the water tank, so that the ice crystal box is also placed in a diagonal state. The ice box frame 3 is integrally disposed obliquely below the water adding device 1, and the two form a spatial connection through the respective openings.

As shown in FIGS. 6 and 7, the top of the ice box frame 3 is an opening 31 for picking up the ice crystal box, and the middle portion is formed by four side plates for accommodating the ice crystal box, and the bottom portion is fixed to the bottom of the water tank. The opening 31 for picking up the ice crystal box at the top of the ice box corresponds to the overall opening of the water adding device through which the human hand can take out or place the ice crystal box. The opening 31 for picking up and dropping the ice crystal box at the top of the ice box is arranged as a diverging opening, which is convenient for picking up and dropping the ice crystal box, and is suitable for Reduce the overall weight of the ice box. Further, a support plate is provided outside the middle of the ice box frame 3 for tilting the ice box frame 3 at a certain angle in the water tank.

Holes

32, 33 for supplying liquid (for example, water) into and out of the side panel of the ice box are also provided. Preferably, holes are provided in each of the side panels at a lower position. The position and shape of the holes can be changed as needed. The water in the water tank can enter the ice box through these holes, and the low temperature ice crystal box close to 0 degree can transfer the cold air to the water, so that the water temperature in the water tank is lowered, and when the cold fan is running, the low temperature water evaporates and absorbs heat to achieve cooling. effect. These holes also help to reduce the overall weight of the ice box. The bottom of the ice box is provided with two screw holes that are fixed to the bottom surface of the tank by screw connections. It is also conceivable to fix the bottom of the ice box frame to the bottom surface of the water tank by snapping or glue bonding.

Preferably, the cooling fan may further include a filter net 4 and an evaporative filter element assembly 5, wherein, as shown in FIG. 2, the filter net 4 and the evaporative filter element assembly 5 are disposed on a side wall adjacent to the side wall of the cold fan where the water adding device is located. .

If the water adding device and the ice box frame structure provided by the embodiment of the present invention are not used, when the cold fan needs to take out or place the ice crystal box, the filter net and the evaporating filter element assembly are opened as shown in FIG. 2, and then the ice crystal box can be placed or taken out. There are two disadvantages to this: 1. Each time you have to take out the filter and evaporative filter components separately before you can take out the ice crystal box, the operation is very inconvenient; 2. The evaporative filter element and the filter are both through the buckle and the cooling fan side. The wall is fixed and often removed to wear the buckle, shortening the service life of the filter and the evaporative filter element assembly. The above embodiment of the present invention avoids the above disadvantages by the rotatably opening and closing water adding device and the ice box frame structure for tilting the ice crystal box, and is convenient to operate, and also prolongs the use time of the filter net and the evaporating filter element assembly buckle. Improved user experience.

The technical content and the technical features of the present invention have been disclosed as above, but those skilled in the art can still make various alternatives and modifications without departing from the spirit and scope of the present invention based on the teachings and disclosures of the present invention. Therefore, the scope of protection of the present invention should not be limited to The disclosure of the present invention is intended to cover various modifications and alternatives and modifications of the invention.
