Description

Technical Field

[0001] The present application relates to the field of fans, and in particular to a rainproof wall-mounted fan. Background Art

[0002] In the indoor ventilation system of a family, a fresh air blower is a relatively common device, which can replenish fresh air from the outside into the room. Although the existing ventilators are constantly innovating and developing, and basically meet people's needs, there is still room for improvement. For example, a rainproof wall ventilator disclosed in China Publication No. CN217274630U includes a tubular ventilator body and a rain shielding mechanism arranged at the air outlet / air inlet end of the tubular ventilator body; the tubular ventilator body includes a first tubular body that runs through the wall; the rain shielding mechanism includes a second tubular body that is connected to the outside of the first tubular body, and the second tubular body is provided with an inclined section at one end away from the first tubular body, and the section is arranged downward. The ventilator is provided with a rain shielding mechanism at the port of the tubular ventilator body located outside, so as to avoid the rain from the outside from blowing into the wall ventilator due to wind force and other effects when it rains. Although the ventilator is equipped with a rain shield to prevent rain, once the natural wind is strong or the wind force of the ventilator increases, rainwater is still easily sucked into the pipe, and the actual use effect is not good. If this continues for a long time, it is still easy to cause certain impacts on the internal electrical appliances. Utility Model Content

[0007] In a specific embodiment, a detachable oil box is provided at the bottom of the protective cover.

[0008] In a specific embodiment, a draw-out opening is provided on the bottom side wall of the protective cover, and the oil container is drawn through the draw-out opening and is disposed at the bottom of the protective cover.

[0009] In a specific embodiment, the oil container is located outside the protective cover and is also provided with a handle.

[0010] In a specific embodiment, a mounting ear plate is fixedly connected to the protective cover.

[0011] In a specific embodiment, sealing gaskets are adhered to the other two side walls of the air outlet.

[0012] In a specific embodiment, the breathable cotton filter rain shield includes a fixed frame plate and a breathable filter cotton plate, and the breathable filter cotton plate is arranged inside the fixed frame plate.

[0022] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0023] See also Figure 1-Figure 4 The present application provides a rainproof wall-mounted fan, including a fan body 10 and a rainproof component 20.

[0024] The fan body 10 is installed at the ventilation port on the wall so that the fan body 10 can exchange the indoor air. The rainproof component 20 can protect the fan body 10 from rain and prevent rainwater from entering the fan body 10 and causing corrosion damage to the fan body 10.

[0025] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The rainproof assembly 20 includes a protective cover 210, which is arranged on the outside of the fan body 10. The side wall of the protective cover 210 is provided with an air outlet 211. The protective cover 210 is provided with a detachable breathable cotton filter rain shield 230 at the air outlet 211. After the fan body 10 is installed at the ventilation port of the wall, the protective cover 210 is installed on it and surrounds the fan body 10, and then the breathable cotton filter rain shield 230 is installed at the air outlet 211 to achieve shielding of the air outlet 211. After the sun comes out, the breathable cotton filter rain shield 230 can expose the rainwater absorbed by itself to the sun to achieve drying, thereby ensuring the next use of rain protection. By setting the protective cover 210 and the breathable cotton filter rain shield 230, rain can still be shielded in a storm, and the breathable cotton filter rain shield 230 can prevent rain from entering the fan body 10. Since the breathable cotton filter rain shield 230 itself is breathable, it will not hinder the exhaust of the fan body 10, thereby increasing the service life of the fan body 10. Through the detachable connection of the breathable cotton filter rain shield 230 to the rain outlet 211, the breathable cotton filter rain shield 230 can be replaced regularly to ensure its rain shielding effect.

[0026] In this embodiment, both side walls of the protective cover 210 at the air outlet 211 are provided with a clearance groove 250, a U-shaped spring 240 is installed inside one of the clearance grooves 250, and both ends of the breathable cotton filter rain shield 230 are arranged inside the two clearance grooves 250, and one end of the breathable cotton filter rain shield 230 is pressed and pressed against by the U-shaped spring 240. The breathable cotton filter rain shield 230 includes a fixed frame plate and a breathable filter cotton plate. Specifically, the breathable filter cotton plate is formed by pressing a rainproof breathable membrane, a filter net and a honeycomb plate. The breathable filter cotton plate is arranged inside the fixed frame plate. Among them, when installing the breathable cotton filter rain shield 230, one end of the breathable cotton filter rain shield 230 is inserted into the yield groove 250 with a U-shaped reed 240 installed on one side, and then squeezed inward so that the other side of the breathable cotton filter rain shield 230 can be inserted into the other yield groove 250, and then under the action of the U-shaped reed 240, the breathable cotton filter rain shield 230 is fixed. When disassembling, the friction force of the hand is used to push the breathable cotton filter rain shield 230 to move to the yield groove 250 on the side with the U-shaped reed 240, so that the other side of the breathable cotton filter rain shield 230 is completely exposed, and the breathable cotton filter rain shield 230 can be removed.

[0027] In this embodiment, an oil container 270 is detachably provided at the bottom of the protective cover 210. A draw-out opening 212 is provided at the bottom side wall of the protective cover 210, and the oil container 270 is drawn out and provided at the bottom of the protective cover 210 through the draw-out opening 212. The oil container 270 is located outside the protective cover 210 and is also provided with a handle 280. If the fan body 10 is on the kitchen wall, the oil container 270 can be used to collect the oil sucked out by the fan body 10 during gas exchange to prevent the inside of the protective cover 210 from being dirty.

[0028] In this embodiment, a mounting ear plate 220 is also fixedly connected to the protective cover 210. The mounting ear plate 220 enables the protective cover 210 to be mounted on the wall.

[0029] In the specific configuration, sealing pads are attached to the other two side walls of the air outlet 211 to increase the sealing performance and prevent rainwater from penetrating into the protective cover 210 .

[0030] Working principle of the rainproof wall-mounted fan:

[0031] After the fan body 10 is installed at the ventilation port of the wall, the protective cover 210 is installed on it and surrounds the fan body 10, and then the breathable cotton filter rain shield 230 is installed at the air outlet 211 to achieve shielding of the air outlet 211, and the breathable cotton filter rain shield 230 can expose the rainwater absorbed by itself to the sun after the sun comes out to achieve drying, thereby ensuring the next rainproof use. Through the arrangement of the protective cover 210 and the breathable cotton filter rain shield 230, rainwater can still be shielded in a storm, and the breathable cotton filter rain shield 230 can prevent rainwater from entering the fan body 10. And because the breathable cotton filter rain shield 230 itself is breathable, it will not hinder the exhaust of the fan body 10, thereby increasing the service life of the fan body 10. By means of the detachable connection of the breathable cotton filtering rain shield 230 and the rain outlet 211, the breathable cotton filtering rain shield 230 can be replaced regularly to ensure its rain shielding effect.
