Description

Technical Field

[0001] The utility model belongs to the technical field of spray fans, and in particular relates to a multifunctional spray fan and a battery pack adapter device thereof. Background Art

[0002] Existing spray fans usually include a fan body and a spray head. The spray head is connected to a water tank so that the spray head can spray out atomized water vapor when the fan body is working. Generally, existing spray fans are all one-piece structures. The fan body cannot rotate forward and backward, so the position of the spray head cannot be adjusted up and down. At the same time, existing spray fans often only blow air through the wind hood, and there is no air guide structure inside the wind hood. The fan consumes high energy and makes a lot of noise when working. Secondly, existing spray fans are often powered by an external plug and need to be used with a socket, which has poor versatility. Therefore, it is necessary to design a multifunctional spray fan and its battery pack adapter to overcome the above difficulties. Summary of the Invention

[0003] In response to the problems existing in the prior art, the utility model designs a multifunctional spray fan and a battery pack adapter device thereof. The wind cover assembly of the utility model can be rotated relative to the base assembly, and the direction of the spray head can be adjusted arbitrarily; when the wind cover assembly is rotated, it can be conveniently taken out by the handle; a side air guide strip assembly is provided in the wind cover assembly to guide the airflow, thereby improving the air outlet effect.

[0004] The invention object of the utility model is achieved through the following technical solutions: a multifunctional spray fan, including a wind cover assembly, base assemblies rotatably connected to the wind cover assembly are provided on both sides of the wind cover assembly, and a rotating adjustment knob for adjusting the angle is provided between the base assembly and the wind cover assembly; a first handle is provided at one end of the wind cover assembly, and a spray head is provided at the other end of the wind cover assembly; a water inlet and several water outlets are provided on the spray head.

[0005] Preferably, the water inlet is provided with a water inlet pipe assembly threadedly connected thereto, the water inlet pipe assembly including a filter head; the water inlet and the water outlet are in communication with each other. When the water inlet pipe assembly is connected to the water inlet, water can be easily supplied to the spray head through the water inlet pipe assembly; the filter head is placed in a water bucket, and the motor in the fan cover assembly is activated to pump water into the spray head.

[0006] Preferably, the water inlet pipe assembly can be threadedly connected to any of the water outlets. When the water inlet pipe assembly is connected to the water outlet, the water inlet is blocked to close the water outlet; thus, when the motor in the fan assembly is operating, only gas can be discharged from the water outlet. The water inlet pipe assembly as a whole functions as an oxygen pump, and the filter head is placed in the water to oxygenate the aqueous solution.

[0007] Preferably, the protrusion of the hood assembly is disposed within a through-hole of the base assembly, and the rotary adjustment knob passes through the base assembly and extends into the interior of the hood assembly; the rotary adjustment knob is threadedly connected to the protrusion of the hood assembly; and a first handle and a spray head are respectively provided at each end of the hood assembly. The hood assembly and the base assembly are rotatable, and the rotary adjustment knob is threadedly connected to the protrusion of the hood assembly. When the hood assembly and the base assembly are rotated to the angle desired by the operator, they are locked by rotating the adjustment knob, thereby maintaining the hood assembly and base assembly in place and preventing further rotation. When the hood assembly rotates, the spray head also rotates accordingly, making it easy to adjust the position of the water outlet and thereby change the diffusion state of the water mist.

[0008] Preferably, the spray head is further provided with a second handle, both of which are positioned toward the back of the hood assembly. The hood assembly is provided with a first handle and a second handle, and both the first handle and the second handle rotate synchronously with the hood assembly, making it easier for the operator to select either the first handle or the second handle to pick up the spray fan according to actual working conditions, thereby improving versatility.

[0009] Preferably, the hood assembly includes a front hood and a rear hood; the front hood and the rear hood are detachably connected, and a side air guide strip assembly is provided between the front hood and the rear hood; the side air guide strip assembly includes an air guide strip rib plate and a plurality of air guide ribs evenly distributed on the air guide strip rib plate, and the outer contour of the air guide strip rib plate matches the outer contour of the hood assembly; the rear hood is provided with a plurality of evenly distributed second ribs, with gaps being left between the air guide ribs and the second ribs. Here, the vertical spacing between the air guide ribs and the second ribs is greater than 6 cm.

[0010] The radial distance between the air guide ribs and the fan blades in the wind cover assembly is relatively far, and there is a large gap between the air guide ribs and the second ribs; therefore, the side air guide strip assembly can guide the airflow to form a cyclone, increase the fan's air outlet speed, and increase the air outlet distance; the air guide ribs can improve the airflow direction, reduce the noise generated by the airflow, and improve energy efficiency.

[0011] Existing spray fans are often plug-in structures. The utility model provides a detachable battery pack adapter on the back of the wind cover assembly, including a battery pack waterproof cavity component, which has a waterproof function and is convenient for installing the battery pack body.

[0013] The battery pack waterproof cavity assembly can be assembled through fasteners and wind cover assemblies, which is convenient for separate assembly and disassembly, thus making the battery pack waterproof cavity assembly have better compatibility.

[0014] Preferably, the battery pack waterproof cavity assembly includes a waterproof cavity, and a seal for sealing the waterproof cavity and the back of the wind cover assembly is provided between the two; the battery pack connecting seat is provided on the inner side of the open end of the waterproof cavity, and the seal is provided around the open end of the waterproof cavity; the back of the wind cover assembly is provided with a first step, and the seal rests on the first step.

[0015] By providing a seal on the first step, a better seal is achieved between the waterproof cavity and the wind shield assembly. A fastener extends from the wind shield assembly and is installed to the battery pack connector, thereby squeezing the seal, so that the seal abuts against the first step to achieve a better sealing effect.

[0016] Preferably, the battery pack waterproof cavity assembly includes a waterproof cavity, and the top open end of the waterproof cavity is provided with a sealing cover rotatably connected to it; a rotating shaft for pivotally connecting the waterproof cavity and the sealing cover is provided between the waterproof cavity and the sealing cover, and a torsion spring for resetting is mounted on the rotating shaft; a water-stop step is provided on the open end of the waterproof cavity, and the water-stop step is arranged around the open end of the waterproof cavity; a buckle is provided on the edge of the water-stop step, and a strip protrusion for cooperating in locking is provided on the sealing cover, and the strip protrusion rests on the buckle when the sealing cover and the waterproof cavity are covered.

[0017] When the sealing cover and waterproof cavity are closed, water is blocked by the water-stopping step, preventing it from entering the waterproof cavity. The buckle and the bar-shaped protrusion cooperate to ensure a tight seal between the sealing cover and the waterproof cavity; as the fan cover assembly rotates forward and backward, the battery pack waterproof cavity component meets the IPX4 waterproof rating. When the bar-shaped protrusion disengages from the buckle, the sealing cover automatically opens via a torsion spring, facilitating replacement of the battery pack.

[0018] Compared with the existing technology, the utility model has the following beneficial effects: 1. The utility model effectively guides the airflow to form a cyclone through the side wind guide strip assembly, thereby increasing the fan's air outlet speed and increasing the air outlet distance; the air guide ribs improve the airflow direction, reduce the noise generated by the airflow, and improve energy efficiency; 2. The water inlet and the water outlet are respectively connected through the water inlet pipe assembly, so that the water inlet pipe assembly not only has the function of filtering the water intake, but also has the function of oxygenating the aqueous solution. 3. The spray head can rotate synchronously with the wind cover assembly, so the spray angle of the spray head can be adjusted at will, thereby changing the diffusion state of the water mist. 4. The utility model adopts a double handle structure, so that the handle is located above the base assembly at any rotation angle of the fan, which is convenient for use and operation. 5. The battery pack waterproof cavity assembly and the wind cover assembly are detachably connected, which has better compatibility and better versatility. The waterproof cavity has a waterproof function and a wider range of usage environments. BRIEF DESCRIPTION OF THE DRAWINGS
