[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] A noise-reducing and silent air source hot air blower comprises a front panel 1 and a hot air blower body 2, wherein the front panel 1 is provided with a hidden air inlet, wherein the hidden air inlet comprises an opening portion 3 arranged on the front side of the front panel 1, wherein the opening portion 3 comprises an upper edge 4 and a lower edge 5, wherein the lower edge 5 extends obliquely upward to the rear of the upper edge 4, wherein the upper edge 4 and the lower edge 5 form an air inlet opening downward.

[0023] like Figure 4-5 As shown in the figure, when the hot air blower is started, the air flows along Figure 5 The direction of the arrow in the figure enters the interior of the hot air blower, and the lower edge 5 extending obliquely upward serves as a guide. Compared with the mesh-type round holes or strip grooves of the air inlet of the traditional hot air blower, the present design has less noise, is more beautiful and is easier to clean.

[0024] Furthermore, the lateral width of the opening 3 is less than or equal to the width of the front face of the front panel 1, and the number of the hidden air inlets is several. When designing, the number and lateral width of the air inlets can be set according to the requirements of different power heat blowers for the air inlet volume. Figure 1As shown, in this embodiment, the lateral width of the opening 3 is set to be equal to the width of the front face of the front panel 1, and the number of hidden air inlets is 2.

[0025] Furthermore, a connecting rib 6 is provided between the upper edge 4 and the lower edge 5. This design can connect the upper edge 4 and the lower edge 5 to enhance the stability of the air inlet structure. Figure 3 As shown, in this embodiment, the number of the connecting ribs 6 is two.

[0026] Furthermore, side air inlets 7 are provided on both sides of the front panel 1 .

[0027] Furthermore, the edges of the upper edge 4 and / or the lower edge 5 are provided with rounded corners. When air passes through the upper edge 4 and the lower edge 5, the rounded corners on the edges have less resistance to the air than the right angles, thereby reducing the wind resistance of the air inlet and achieving the effect of reducing noise. Figure 6 As shown, in this embodiment, the edges of the upper edge 4 and the lower edge 5 are both provided with rounded corners.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
