[0017] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0018] The embodiments of the present application are:

[0019] See also Figure 1-Figure 3 , Figure 1 This is a schematic diagram of the overall structure of the fiber fabric air duct with a fabric check valve of the utility model. Figure 2 This is a schematic structural diagram of the fiber cloth 104 of the present invention. Figure 3 It is a structural diagram of the magnet 107 and the iron block 108 of the present invention.

[0020] The fiber fabric air duct with a fabric check valve of the present invention comprises a fan body 101, an air duct 102, a support frame 103, a fiber fabric 104, a hook 105, a groove 106, a magnet 107, an iron block 108, a blocking net 109, a vent 110, and an inspection window 111. This solves the problem of reverse airflow during use of the fiber fabric air duct, which is incapable of preventing airflow from flowing backward due to the lack of a check device in the prior art. It is understood that the above solution can also be used to improve practicality.

[0021] In this embodiment, the fan body 101 is the existing technology. Through the air duct assembly, the problem of reverse flow of air in the fiber fabric air duct during use is solved, and the existing technology does not have a non-return device and cannot achieve air flow non-return.

[0022] The air duct 102 is fixedly connected to the fan body 101 and is located on one side of the fan body 101. The support frame 103 is fixedly connected to the air duct 102 and is located inside the air duct 102. The fiber cloth 104 is in multiple pieces, and multiple pieces of the fiber cloth 104 are evenly arranged on the support frame 103. The hook 105 is installed on the fiber cloth 104 and is located on one side of the fiber cloth 104. The groove 106 is opened on the support frame 103. The hook 105 is connected to the fiber cloth 104. The groove 106 cooperates with the air duct 102 to connect with the fan body 101 for conveying cold air or hot air. The support frame 103 is fixedly installed in the air duct 102. The support frame 103 is a hollow rectangular frame with a partition in the middle to separate the support frame 103 into two or more independent cavities. The number of the fiber cloth 104 is multiple (for ease of understanding, only two pieces of the fiber cloth 104 are drawn in the accompanying drawings). One side of the fiber cloth 104 is fixedly connected to the support frame 103 (from As can be seen from the drawings of the specification, the fiber cloth 104 of the uppermost layer is connected to the outer frame of the support frame 103, and the fiber cloth 104 of the lower layer is connected to the partition of the support frame 103), and the other side is suspended. When the air is supplied in the forward direction, the fiber cloth 104 is blown up and the air flow passes normally. The hooks 105 are sewn on the suspended side of the fiber cloth 104. There are multiple hooks and they are arranged side by side. The grooves 106 are opened on the partition of the support frame 103 (the grooves 106 of the bottom layer are opened on the bottom of the support frame 103). The fiber cloth 104 is a fiber fabric and droops in a natural state. The hook 105 hooks the groove 106, thereby blocking the cavity of the support frame 103, thereby achieving non-return. By arranging the fiber cloth 104 in the air duct 102 and cooperating with the hook 105 and the groove 106, the air flow non-return is achieved, which solves the problem that the fiber fabric air duct has a reverse flow of air during use, and the prior art does not have a non-return device and cannot achieve air flow non-return.

[0023] Secondly, the magnet 107 is installed on the support frame 103 and is located on the side of the support frame 103 close to the fiber cloth 104; the iron block 108 is installed on the fiber cloth 104 and cooperates with the magnet 107. The number of the magnets 107 is multiple and they are embedded in the support frame 103 side by side. The iron block 108 is sewn to the suspended side of the fiber cloth 104, corresponding to the magnet 107 (the magnetic force of the magnet 107 is small, and the fiber cloth 104 can be blown away normally when the fan body 101 is supplying air. The magnet 107 and the iron block 108 are used to assist the hook 105 to hang into the groove 106 when the fiber cloth 104 is in a naturally drooping state). The iron block 108 is adsorbed by the magnet 107, so that the hook 105 can be accurately hung in the groove 106.

[0024] At the same time, the blocking net 109 is fixedly connected to the support frame 103 and is located inside the support frame 103. The blocking net 109 is fixedly installed in the cavity of the support frame 103. The blocking net 109 can ensure that the fiber cloth 104 cannot be blown up in the reverse direction.

[0025] In addition, the vent 110 is opened on the air duct 102 and is located at one end of the air duct 102 away from the fan body 101. The vent 110 is set at the bottom of the air duct 102. The air can be discharged from the air duct 102 through the vent 110.

[0026] Finally, the inspection window 111 is detachably connected to the air duct 102 and is located on one side of the air duct 102 close to the support frame 103. The inspection window 111 is installed on the air duct 102 through a zipper. When maintenance and inspection of the interior of the air duct 102 is required later, the zipper can be pulled to open the inspection window 111 for maintenance and inspection. Through the inspection window 111, it is convenient to perform maintenance and inspection on the air duct 102 later.

[0027] In this embodiment, when the airflow passes through in the forward direction, the fiber cloth 104 will be blown up, the cavity of the support frame 103 will be in an open state, and the airflow can pass through normally; the fiber cloth 104 will naturally droop due to gravity, blocking the cavity of the support frame 103. In addition, with the cooperation of the magnet 107 and the iron block 108, the hook 105 will hook into the groove 106 to ensure that the fiber cloth 104 blocks the cavity of the support frame 103, thereby realizing airflow check, solving the problem that the fiber fabric air duct has reverse flow during use, and the existing technology does not have a check device and cannot achieve airflow check.

[0028] The above disclosure is merely one or more preferred embodiments of the present application and is not intended to limit the scope of the present application. A person skilled in the art will understand that all or part of the processes of the above embodiments and equivalent changes made in accordance with the claims of the present application are still within the scope of the present application.
