Description

Technical Field

[0001] The invention relates to the technical field of fans, in particular to a novel spray fan with movable power supply. Background Art

[0002] A spray fan is a device that uses an electric fan to rotate and a spray device to cool down and relieve heat. It can speed up air circulation while evenly increasing air humidity. The structure of a conventional spray fan is not much different from that of an ordinary floor fan. Both use a chassis as the center of gravity at the bottom of the fan to fix the entire upper structure of the fan. A spray fan only has a water tank that can store water on the chassis, and then the water is transported to the fan's mesh cover through an external duct, and the water mist is blown out by the rotation of the fan blades.

[0003] However, the existing structure of the spray fan has many defects in actual use. For example, since the general use place of the spray fan is outdoors, and the general spray fan has a power cord inside the body to connect to a fixed power supply, it is not possible to find a stable power supply outdoors and cannot be used, which brings great inconvenience to consumers; secondly, the conventional spray fan chassis is fixed and heavy, and consumers cannot easily move the spray fan. When using the spray fan outdoors, such a chassis structure also makes the spray fan extremely inconvenient to move; finally, since the current mainstream spray fan is similar to the conventional vertical floor fan structure, the fan head is set at a high height, but such a structure makes the area of ​​water mist diffused too large, which is easy to get on others or other electrical appliances, causing certain safety hazards. Therefore, there is an urgent need for a spray fan with a more reasonable structure that can solve the existing defects. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a new type of spray fan with a more reasonable structure and movable power supply in view of the problems existing in the prior art.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: A new type of spray fan with movable power supply, comprising a fan assembly and an outer bracket assembly installed outside the fan assembly. The fan assembly includes fan blades, a mesh cover installed outside the fan blades, and a mesh cover ring installed between the mesh covers. An installation bin with a fixing plate is arranged inside the mesh cover. A water supply pipe is installed on the fixing plate. A plurality of convex water supply joints are evenly distributed on the water supply pipe. A plurality of limit posts are arranged on the fixing plate corresponding to the water supply joints. One side of the water supply pipe is connected to a water delivery pipe. The fan assembly is installed on one side of the outer bracket assembly, and protective shells are symmetrically installed on the other side. The protective shells enclose a power supply accommodation bin, and a battery pack is installed in the power supply accommodation bin. A power supply accommodation bin upper cover is installed on the upper side of the power supply accommodation bin and is installed on the protective shell through installation parts on both sides of the power supply accommodation bin upper cover. A control panel is arranged on the upper side of the power supply accommodation bin. A caster is installed on one side below the outer bracket assembly, and a telescopic rod is installed on the other side.

[0006] Preferably, the outer bracket assembly includes a plurality of connecting brackets and corner guards installed between the connecting brackets. The corner guards include a three-way first corner guard and a second corner guard, as well as two-way third, fourth, fifth, and sixth corner guards. Fixed corner guards parallel to each other are symmetrically arranged between the connecting brackets on the lower side of the fan assembly.

[0007] Preferably, the first corner guard is composed of a rectangular branch and a long branch perpendicular to the rectangular branch. The second corner guard is composed of a "匚"-shaped branch and a short branch perpendicular to the "匚"-shaped branch. A connecting bracket is installed between the long branch and the short branch. An integral fourth corner guard and symmetrically arranged and parallel sixth corner guards are installed between the connecting brackets on the lower side of the first corner guard. The third and fifth corner guards parallel to each other are symmetrically arranged on the connecting bracket on the lower side of the second corner guard.

[0008] Preferably, a rotating shaft is arranged on the fourth corner guard on one side of the mesh cover ring. An outer adapter plate with one side connected to the mesh cover ring is installed in the fourth corner guard. Another outer adapter plate is correspondingly installed inside the protective shell. An inner adapter plate adapted to the outer adapter plate is installed inside the mesh cover ring.

[0009] Preferably, a water pump is installed below the battery pack in the power supply accommodation bin. One end of the water pump is connected to the water delivery pipe, and the other end is connected to a water inlet pipe extending out of the protective shell.

[0010] Preferably, a caster is installed on the lower side of the fifth corner guard. An opening is arranged on one side of the sixth corner guard, and a telescopic rod is installed in the opening. A handle is arranged at the front end of the telescopic rod.

[0011] Preferably, a motor connected to the driving shaft of the fan blade is installed at the rear side of the fan blade. The motor is a 48V DC brushless motor.

[0012] Compared with the prior art, the new type of spray fan with movable power supply of the present invention has the following beneficial effects: when used outdoors, there is no need to find an external power source, and the spray fan can be driven by the power pack carried by itself, which greatly improves the portability and stability of the spray fan outdoors; by setting an external bracket component instead of the traditional chassis, the height of the spray fan is reduced, which greatly increases the structural stability and strength of the spray fan, and also prevents the water mist from spreading to other electrical appliances, thereby improving the safety of the spray fan. In addition, the replaceable spray head and the mesh cover ring that can be flipped back and forth further enhance the consumer's experience. BRIEF DESCRIPTION OF THE DRAWINGS
