DETAILED DESCRIPTION

[0020] The essential features of the present utility model are further described below in conjunction with the accompanying drawings and specific implementation methods.

[0021] Embodiment 1:

[0022] This embodiment provides a fan assembly structure.

[0023] like Figure 1 and 2A fan assembly structure shown is composed of a housing 1 with a volute 2 inside, a fan blade 3 arranged in the volute 2, and a functional panel arranged below the housing 1. The middle part of the bottom surface of the housing 1 is provided with an air outlet 4 and an air inlet 5 connected to the volute 2. The air outlet 4 and the air inlet 5 are arranged along the length direction of the housing 1 to form a linear ventilation area, and the linear ventilation area is exposed to the outside through a functional panel with differentiated functions. By setting a linear ventilation area to cooperate with different functional panels for installation, the scope of application is effectively expanded, and the installation of a large panel and a linear panel 11 is satisfied at the same time, and the structure is effectively simplified, which is convenient for assembly and use, and improves the user experience.

[0024] In this embodiment, the functional panel is a square panel 6, and the square panel 6 is provided with air outlet holes 8 and air inlet holes 7 corresponding to the air outlet 4 and the air inlet 5, respectively. The size of the square panel 6 is consistent with the size of the adjacent decorative panel, so that the square panel 6 can not only effectively block the fan, but also match and splice with the adjacent decorative panel to form a flat decorative surface. The decorative panel is a large-size panel with a width of 30 cm or 60 cm, ensuring that the square panel 6 can fill the space reserved between the decorative panels, thereby achieving the matching use of the square panel 6 and the decorative panel.

[0025] In this embodiment, the top surface of the square panel 6 is fastened to the bottom surface of the shell 1 by fasteners, which not only ensures that the square panel 6 can be connected flush with the adjacent decorative panel at the same height, but also effectively blocks the fan, improves the aesthetics, and facilitates disassembly and assembly, thereby improving the convenience of assembly.

[0026] In this embodiment, the volute 2 is located in the middle of the housing 1, the bottom surface of the volute 2 is exposed and forms the air inlet 5, and the two air outlets 4 are symmetrically arranged on both sides of the air inlet 5, so that the air inlet 5 and the air outlet 4 are arranged linearly. The two sides of the volute 2 are connected to the corresponding air outlet 4 through the blowing channel 16, so that the air outlet 4 and the air inlet 5 are arranged on the same straight line and form a linear ventilation area, which is convenient for cooperation with the square panel 6 provided with the air inlet through hole 7 and the air outlet through hole 8.

[0027] In actual operation, the housing 1 includes a base 14 with an exposed bottom surface and a cover plate 15 covering the bottom surface of the base 14. The base 14 is provided with a volute 2 and a blowing channel 16 disposed at both ends of the volute 2. The cover plate 15 is provided with an air inlet 5 vertically aligned with the volute 2 and an air outlet 4 corresponding to the end of the blowing channel 16. The cover plate 15 covers the bottom surface of the base 14 and encloses the blowing channel 16, the ventilation channel 17 and the volute 2, ensuring that the airflow flows in a well-sealed space, preventing leakage, effectively reducing wind resistance, and improving airflow transmission efficiency.

[0028] In actual operation, the side wall of the housing 1 is provided with a ventilation port 18, a ventilation channel 17 is provided between the volute 2 and the ventilation port 18, the axes of the blowing channel 16 and the ventilation channel 17 are arranged tangentially along the periphery of the volute cavity in opposite directions, and the fan blades 3 switch the airflow path between the blowing channel 16 and the ventilation channel 17 by forward and reverse bidirectional rotation. The periphery of the volute 2 is provided with a ventilation channel 17 connected to the outdoor space, the axes of the blowing channel 16 and the ventilation channel 17 are arranged tangentially along the periphery of the volute cavity in opposite directions, and the fan blades 3 switch the airflow path between the blowing channel 16 and the ventilation channel 17 by forward and reverse bidirectional rotation. The axes of the blowing channel 16 and the ventilation channel 17 are arranged tangentially along the periphery of the snail cavity in opposite directions. The fan blades 3 deliver the airflow to the blowing channel 16 or the ventilation channel 17 through forward and reverse bidirectional switching, thereby realizing the switching of the airflow flow path in the fan, which not only simplifies the structure, facilitates production, and reduces equipment costs, but also effectively reduces the volume of the shell 1 and improves the user experience.

[0029] When in use, the fan blade 3 is driven by the motor to rotate forward and reverse, thereby switching the airflow path between the blowing mode of exhausting through the blowing channel 16 and the ventilation mode of exhausting through the ventilation channel 17. Specifically, one end of the blowing channel 16 is tangentially arranged counterclockwise along the periphery of the volute 2, and the end of the ventilation channel 17 is tangentially arranged clockwise along the periphery of the volute 2. When the fan blade 3 rotates in the counterclockwise direction, the fan blade 3 drives the airflow to flow counterclockwise along the volute 2 and pour into the blowing channel 16. When the fan blade 3 rotates in the clockwise direction, the fan blade 3 drives the airflow to flow clockwise along the volute 2 and pour into the ventilation channel 17, so that the airflow can switch the flow path by adjusting the rotation direction of the fan blade 3, effectively simplifying the structure, facilitating assembly and use, and reducing equipment costs.

[0030] Embodiment 2:

[0031] Compared with the first embodiment, this embodiment provides another fan assembly structure.

[0032] like Figure 3 In the fan assembly structure shown, the middle of the square panel 6 is provided with a light-emitting member 9 exposed downward, and the light-emitting member 9 is arranged in the air inlet hole 7. The light-emitting member 9 and the air inlet hole 7 are arranged in the center so that the outer edge of the light-emitting member 9 and the periphery of the air inlet hole 7 enclose a ring-shaped air inlet passage. The air inlet 5 is circular, and the air inlet hole 7 has the same profile as the air inlet 5. The light-emitting member 9 is circular, and the diameter of the light-emitting member 9 is smaller than the air inlet hole 7, so that the light-emitting member 9 is installed in the air inlet hole 7 and encloses a ring-shaped air inlet passage, which not only uses the light-emitting member 9 to shield the fan blades 3, but also meets the air inlet demand of the volute 2 by reserving the air inlet passage.

[0033] In this embodiment, a light-transmitting plate 10 is provided below the light-emitting element 9, and the light-transmitting plate 10 covers the light-emitting element 9 from bottom to top and is fixedly connected. The light-transmitting plate 10 covers the bottom surface of the light-emitting element 9, which not only facilitates the light generated by the light-emitting element 9 to pass through the light-transmitting plate 10 downward and diffuse outward, but also protects the light-emitting element 9.

[0034] In this embodiment, the light-transmitting plate 10 is sealed and covered on the bottom surface of the light-emitting element 9 , so that the light-emitting element 9 is sealed and wrapped to prevent dust and water vapor from entering, thereby effectively extending the service life of the light-emitting element 9 .

[0035] The other features and effects of the fan assembly structure described in this embodiment are consistent with those in the first embodiment and will not be described in detail.

[0036] Embodiment three:

[0037] Compared with the first embodiment, this embodiment provides another fan assembly structure.

[0038] like Figure 4 In the fan assembly structure shown, the functional panel is a long linear panel 11, and the linear panel 11 is provided with vents extending along its length, and the linear ventilation area vertically overlaps with the vents, so that the air inlet 5 and the air outlet 4 are both connected to the outside through the vents. The linear panel 11 is used to be installed in the long strip gap reserved between adjacent decorative panels. The linear panel 11 can not only realize air flow between the fan and the indoor space through the vents to ensure the normal operation of the fan, but also cooperate with the adjacent decorative panels to shield the fan, effectively improving the aesthetics.

[0039] In this embodiment, the assembly structure includes two triangular keels 13 arranged at preset positions and arranged in parallel at the same height. The top surface of the linear panel 11 is connected to the triangular keels 13 by inserting strips, and the shell is overlapped and installed on the top surface of the triangular keels 13 so that the vents are vertically aligned with the linear ventilation area. The distance between the two triangular keels 13 matches the width of the linear panel 11, and the side edge of the top surface of the linear panel 11 extends upward to form an insert strip. The linear panel 11 is tightly attached to the adjacent decorative panel and is fixedly connected by the corresponding triangular keels 13, which not only ensures that the linear panel 11 is vertically aligned with the linear ventilation area of ​​the fan, but also ensures that the linear panel 11 is flush with the adjacent decorative panel.

[0040] In this embodiment, an air guide plate 12 that can be swung and switched by a swing arm is provided in the air vent. The air guide plate 12 is driven by a motor to switch between a blocking state and an air guiding state. The air guide plate 12 in the blocking state can be used to block the air vent to improve the aesthetics, and the air guide plate 12 in the air guiding state can also be used to guide and redirect the airflow to ensure that the airflow can be transported to the preset space, thereby increasing the area of ​​the airflow transport area and improving the user experience.
