[0037] In addition, the technical features involved in the different embodiments of the utility model described below can be combined with each other as long as there is no conflict between them.

[0038] As Figure 1 Indicated, the embodiment provides a blowing system, comprising, cabinet 1, heating assembly 2 and blowing assembly 3.Cabinet 1 is provided with the flow channel suitable for airflow circulation inside, and the air inlet 11 and the air outlet 12 are arranged on the side wall of the cabinet 1.The flow channel is communicated with the outside through the air inlet 11 and the air outlet 12.Heating assembly 2 is arranged in the flow channel, and heating assembly 2 is arranged between the air inlet 11 and the air outlet 12, and heating assembly 2 is suitable for heating the airflow flowing through heating assembly 2.Blowing assembly 3 has several blowing assemblies 3, which are arranged at the air inlet 11 and the air outlet 12;The air inlet 11 and the air outlet 12 are arranged on the cabinet 1, the distance between the air inlet 11 and the air outlet 12 is shortened, and the blowing assembly 3 is arranged at the air inlet 11 and the air outlet 12, which can ensure that the airflow entering the flow channel is blown out, and the distance between the air inlet 11 and the air outlet 12 is shortened, and the blowing assembly 3 with small power and small volume is arranged at the air inlet 11 and the air outlet 12, by increasing the number of blowing assembly 3, the volume and cost of blowing assembly 3 can be reduced while meeting the demand of equipment for blowing assembly 3.

[0039] It needs to be explained that, as Figure 2 Indicated, the blowing assembly 3 selects the small power and small volume axial flow fan, and the small volume axial flow fan can increase the overall aesthetic appearance.As an alternative embodiment, the blowing assembly 3 can also select centrifugal fan, cross-flow fan or multi-fan series-parallel design.

[0040] It should be noted that, as shown in Figure 3 The heating assembly 2 is selected as a PTC thermistor, which has the advantages of good stability and strong overload capacity. The airflow passes through the pores in the interior of the heating assembly 2 and carries the heat generated by the heating assembly 2, thereby achieving the heating effect on the airflow. As an alternative embodiment, a resistance wire heating can also be selected.

[0041] Further, a handheld blowing structure 4 is provided, which is arranged on one side of the cabinet 1 and communicates with the flow-through channel. The handheld blowing structure 4 communicates with the flow-through channel through a pipeline, and the airflow in the flow-through channel is transmitted to the handheld blowing structure 4 through the pipeline. The handheld blowing structure 4 can blow to places that cannot be blown by the air outlet 12, thereby increasing the practicability of the device.

[0042] Further, the air outlet 12 is provided with a plurality of air outlets 12, which are arranged at intervals along the airflow direction. The plurality of air outlets 12 can be applied to different scenes, such as human warming area, towel and clothing drying area, pet drying area, and ground drying area.

[0043] Further, the air inlet 11 includes an indoor air inlet 111 and an outdoor air inlet 112, which are oppositely arranged on the side wall of the cabinet 1. The indoor air inlet 111 is suitable for indoor air to enter the flow-through channel, and the outdoor air inlet 112 is suitable for outdoor air to enter the flow-through channel. In this embodiment, the indoor air inlet 111 and the outdoor air inlet 112 are oppositely arranged on the side wall of the cabinet 1. As an alternative embodiment, the indoor air inlet 111 and the outdoor air inlet 112 can also be arranged at other positions. By arranging the indoor air inlet 111 and the outdoor air inlet 112, the air intake of the cabinet 1 can be further increased, and the air volume of the air outlet 12 can be ensured.

[0044] Further, the cabinet 1 includes a plurality of wind baffles 5, which are arranged corresponding to the air outlets 12. The wind baffles 5 are arranged perpendicular to the airflow direction. When the airflow meets the wind baffles 5, the flow direction of the airflow will flow along the direction of the wind baffles 5, thereby being guided out of the air outlets 12. By arranging the wind baffles 5, the airflow flow rate at the air outlets 12 can be increased.

[0045] Further, the wind blocking area of the wind baffles 5 is increased along the airflow direction, thereby ensuring that each wind baffle 5 can block the airflow. The wind baffle 5 located near the air inlet prevents the wind baffle 5 behind from being blocked, thereby ensuring that each wind baffle 5 can intercept a certain amount of air.

[0046] Further, the air blowing system further comprises an outdoor exhaust port, which is arranged on the side wall of the cabinet body 1 and is in communication with the outdoor. The outdoor exhaust port 13 is adapted to exhaust the air in the flow channel to the outdoor. The outdoor exhaust port 13 and the outdoor air inlet 112 form a fresh air system, so that the indoor and outdoor form an air exchange, so that the indoor and outdoor form a certain flow, and the indoor air is fresh.

[0047] Further, the air blowing system further comprises an outdoor exhaust port, which is arranged on the side wall of the cabinet body 1 and is in communication with the outdoor. The outdoor exhaust port 13 is adapted to exhaust the air in the flow channel to the outdoor. The outdoor exhaust port 13 and the outdoor air inlet 112 form a fresh air system, so that the indoor and outdoor form an air exchange, so that the indoor and outdoor form a certain flow, and the indoor air is fresh.

[0048] It should be noted that different modules can be additionally arranged at different air outlets 12, such as a steam module for clothes care or water vapor disinfection, an anion module for deodorization and sterilization, a fragrance module for air purification, etc.

[0049] Obviously, the above embodiments are only examples for clearly illustrating, but not limit the embodiments. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, all the embodiments need not and cannot be exhausted. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
