DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following further details the specific embodiments of the utility model with reference to the accompanying drawings.

[0028] Embodiment 1. Consisting of Figures 1 to 5Provided is an air volume auxiliary diffusion device for a household device, including a housing and a diffusion structure. The housing consists of a first support plate 18 at the air outlet end 4 of the diffusion structure, a second support plate 19 at the air inlet end 3 of the diffusion structure, a connecting plate 20 located between the first support plate 18 and the second support plate 19 and forming an open space at both ends with the first support plate 18 and the second support plate 19, and an end plate 21 located at the opening of the space formed by the first support plate 18, the second support plate 19 and the connecting plate 20 for closing the opening. The diffusion structure is located in the enclosed space formed by the above structures. Constructing the housing with the above structure, on the one hand, the separate design of each structure can reduce the processing procedures and processing costs, and on the other hand, the assembled design of multiple structures is convenient for disassembly and maintenance.

[0029] The diffusion structure is installed in the housing for transporting hot air or cold air, and under the action of the diffusion structure, the hot air or cold air generated by the household device that generates hot air or cold air is further condensed and transported.

[0030] The diffusion structure includes an air volume driving component 1, a fixing component 2 and an air duct arranged in sequence along the direction of hot air or cold air transportation. The air volume driving component 1 strengthens the hot air or cold air generated by the household device and transports it outward through the reasonable condensation of the air duct.

[0031] The fixing component 2 is fixedly connected to the air duct and is used for supporting and fixing the air volume driving component 1. Under the action of the fixing component 2, the detachable connection between the air volume driving component 1 and the air duct is realized, so that the appropriate air volume driving component 1 can be selected according to the appropriate situation.

[0032] The air volume driving component 1 is a fan with the wind direction facing the air duct. The fan blows air into the air duct, so as to achieve the effect of strengthening the hot air or cold air. The fixing component 2 is a hollow frame body and is fixed on the air duct by bolts. The outer shell of the fan is fixedly connected to the fixing component 2.

[0033] The air duct includes an air inlet end 3, an air outlet end 4 and a connecting part 5 along the direction of hot air or cold air transportation. The plane where the air inlet end 3 is located forms an angle of 60 degrees to 110 degrees with the plane where the air outlet end 4 is located. The plane where the air inlet end 3 is located and the plane where the air outlet end 4 is located are optimally set to 90 degrees, and their projections overlap. Under the action of the above angles, the condensation effect of hot air or cold air can be improved.

[0034] The connecting part 5 is used to connect the air inlet end 3 and the air outlet end 4, and its cross-section along the direction of hot air or cold air transportation is arc-shaped. The inner arc of the connecting part 5 is smaller than the outer arc. The arc shape and arc setting of the connecting part 5 are also for better condensing of hot air or cold air.

[0035] The area of the air inlet end 3 is larger than that of the air outlet end 4. The larger area of the air inlet end 3 is set to increase the air intake volume, and the smaller area of the air outlet end 4 is set to increase the flow rate of the hot air or cold air ejected, so that the hot air or cold air can be diffused to a farther distance.

[0036] The air duct is integrally injection-molded, and the air duct can be integrally injection-molded through a mold.

[0037] The diffusion structure is provided in plurality within the housing. The housing is provided with air outlets 11 corresponding to and for the use of the air outlet end 4 one by one. A sealing gasket 12 corresponding to the air outlet 11 is provided on the air outlet end 4. The sealing gasket 12 is used to increase the tightness at the air outlet 11, so that the hot air or cold air can be ejected better from the air outlet 11;

[0038] The housing is provided with air inlets 13 corresponding to and for the use of the air inlet end 3 one by one. A dust-proof net 14 is provided at the air inlets 13. The dust-proof net 14 is used to increase the service life of the air volume driving component 1.

[0039] It further includes a control structure provided within the housing for controlling the air volume driving component 1. The control structure includes a battery 22 for supplying power to the air volume driving component 1, a circuit board 23 for opening and closing the air volume driving component 1, and a charging interface 24 for charging the battery 22.

[0040] It further includes a fixing structure provided outside the housing for fixing the housing. The fixing structure includes a support plate 15 extending beyond the outer edge surface of the housing, and a pressing component 16 provided on one side of the support plate 15 and capable of approaching or departing from the side surface of the support plate 15. The support plate 15 positions the household device that generates hot air or cold air, and the pressing component 16 approaches or departs from the support plate 15 to adapt to the sizes of more household devices.

[0041] There are two pressing components 16. The two pressing components 16 are symmetrically arranged along the hot air or cold air conveying direction and are located on both sides of the air inlet 13.

[0042] The pressing device can adopt a bracket and a screw. A plastic block located between the support plate 15 and the screw is fixed on the screw. Under the action of the thread, the plastic block approaches or departs from the support plate 15.

[0043] The housing is provided with a buffer pad 17 for buffering the household device between the two pressing components 16. The buffer pad 17 contacts the outer edge surface of the household device. On the one hand, it prevents damage to the outer edge surface of the household device when the housing is fixed to the air outlet 11 of the household device, and on the other hand, it tightly limits and fixes the housing through the buffer pad 17.

[0044] Embodiment 2

[0045] From the attached description Figures 6 - 7It is concluded that the air duct is assembled and connected by two side parts symmetrically arranged along the direction of hot air or cold air transportation. The two side parts are injection-molded respectively, which reduces the mold design amount and is more convenient for production. A sealing groove 6 is formed on one side part, and a sealing plate 7 inserted into the sealing groove 6 is arranged on the other side part. The sealing plate 7 and the sealing groove 6 are used to increase the airtightness of the air duct.

[0046] A plurality of limiting rings 8 distributed on the outer edge surface of the side part are arranged on one side part, and a limiting plate 9 inserted into the limiting rings 8 is arranged on the other side part. One end of the limiting plate 9 extends out of the limiting rings 8 and is provided with a stop block 10 for blocking the movement of the limiting plate 9. The limiting rings 8, the limiting plate 9 and the stop block 10 are used to assemble the two side parts more tightly together.

[0047] Since the air duct in the second embodiment is assembled and formed by two side parts, in terms of the design requirements of the injection molding die, the design amount is less than that of the whole air duct. Therefore, the second embodiment is a preferred embodiment compared with the first embodiment.

[0048] When the utility model is in use, the user rotates the screw in the pressing component 16 so that the distance between the plastic block and the support plate 15 in the pressing component 16 can accommodate the household equipment. The household equipment is used in cooperation with the air inlet 13. The buffer cushion block 17 is attached to the outer edge surface of the household equipment. Under the cooperation of the plastic block and the support plate 15 in the pressing component 16, the housing is fixed on the household equipment. The air volume driving component 1 is started to enhance the hot air or cold air generated by the household equipment, so that the hot air or cold air generated by the household equipment passes through the air duct and is ejected from the air outlet 11, so that the hot air or cold air can be dispersed into the room faster.

[0049] In the utility model, the connecting part is arranged in an arc shape and the radian of the inner edge surface is smaller than that of the outer edge surface, which can further condense the hot air or cold air generated by the household equipment, so that the hot air or cold air generated by the household equipment can be dispersed into the room faster;

[0050] The utility model adopts a diffusion structure to diffuse the hot air or cold air generated by the household equipment outward. The household equipment can be an air conditioner or an electric heater, or some equipment with a large heat production. It can be used for an air conditioner or an electric heater to accelerate the change of indoor temperature, and for some equipment with a large heat production to accelerate the cooling of the equipment, thereby increasing the service life of the equipment;

[0051] The utility model adopts the cooperation of the pressing component and the support plate, so that the utility model can be applied to a wider range of equipment, increasing the application range of the utility model and improving the universality of the utility model;

[0052] The utility model adopts the setting that the area of the air outlet end is smaller than that of the air inlet end. On the one hand, the larger air inlet end is used to expand the air intake of hot air or cold air. On the other hand, the smaller air outlet end and Bernoulli's principle are used to make the air flow rate at the air outlet end of the air outlet end higher, so that the hot air or cold air flowing out from the air outlet flows outwards for a longer distance, achieving the purpose of reducing the dispersion time of hot air or cold air.
