[0025] Filter device 200, ring plate 210, filter element body 220;

[0026] Air inlet shroud 300, center plate 310, ribs 320; Detailed Implementation

[0027] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0028] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intermediary element (e.g., the third element) between the element and the other element.

[0030] An embodiment of this utility model provides a horizontal fan, such as... Figure 1-3As shown, the fan body 100 and a filter device 200 are included. A groove 101 is provided on the top surface of the fan body 100, an air inlet 102 is provided on the bottom wall of the groove 101, and an air outlet 103 is provided on the front side of the fan body 100. When the fan is working, outside air enters the fan body 100 through the air inlet 102 and is then blown out through the air outlet 103. The filter device 200 is inserted into the groove 101. On the one hand, the groove 101 helps to position the filter device 200, preventing misalignment during installation; on the other hand, the depth of the groove 101 provides sufficient space to secure the filter device 200. The filter device 200 is also detachably connected to the fan body 100, therefore, the filter device 200 can be removed from or installed on the fan body 100 as needed.

[0031] When the filter device 200 is fixed to the fan body 100, outside air is filtered by the filter device 200 before flowing into the fan body 100, resulting in cleaner air being blown out of the outlet 103. When the filter device 200 is removed from the fan body 100, outside air is not filtered by the filter device 200 and is directly blown out of the outlet 103. In this embodiment, the filter device 200 is externally mounted and uses a detachable connection structure, which facilitates the installation and removal of the filter device 200. The fan can be switched freely between "clean air supply" and "normal air supply" operating modes as needed by the user, offering high flexibility and a wide range of applications.

[0032] In some embodiments, the sidewalls of the groove 101 are provided with a plurality of snap fasteners 104. The filter device 200 includes an annular plate 210, which may be annular with a central through-hole to allow airflow through the annular plate 210. The annular plate 210 is inserted into the groove 101, and the snap fasteners 104 are fastened to the top surface of the annular plate 210. The snap fastener connection allows for installation and disassembly without the aid of other tools, making the operation simpler and enabling quick installation and disassembly. Since the groove 101 is located on the top surface of the fan assembly 100, the filter device 200 is inserted into the groove 101 and, under its own weight, can be held in the groove 101. Therefore, the snap fastener connection is sufficient to install and fix the filter device 200 on the fan body 100.

[0033] Furthermore, the filter device 200 is a filter element, which includes a filter element body 220 and an annular plate 210 fixed to the bottom of the filter element body 220. The outer diameter of the annular plate 210 is larger than the outer diameter of the filter element body 220, which allows space to be reserved on the top surface of the annular plate 210, and the buckle 104 can be fastened to the periphery of the top surface of the annular plate 210.

[0034] In some embodiments, such as Figure 1 and Figure 4As shown, the bottom surface of the fan body 100 is provided with multiple downward-protruding support rods 140. When the entire fan is placed horizontally, the support rods 140 can support the fan body 100. The top surface of the fan body 100 is provided with insertion holes 130 that are adapted to the support rods 140. The support rod 140 of one of the two horizontal fans can be inserted into the insertion hole 130 of the other to realize the stacking of the two horizontal fans. This allows multiple fans to be stacked, which is convenient for centralized storage or transportation of products and can reduce the space occupied.

[0035] In some embodiments, such as Figure 1 and Figure 5 As shown, an air inlet shroud 300 is provided at the air inlet 102. The air inlet shroud 300 includes a central disk 310 and multiple ribs 320. The central disk 310 is located at the center of the air inlet 102. The two ends of the ribs 320 are connected to the outer side wall of the central disk 310 and the inner side wall of the air inlet 102, respectively. A gap is formed between adjacent ribs 320, allowing airflow to enter the fan body 100 through the gap. In the radial and outward direction, the top surface of the ribs 320 is arc-shaped, and the height of the ribs 320 gradually decreases. Thus, the entire air inlet shroud 300 forms an arc-shaped structure with a central arch, a design that reduces air intake noise.

[0036] In some embodiments, such as Figure 1 and Figure 5 As shown, the fan body 100 includes an upper cover 110 and a lower cover 120. The upper cover 110 and the lower cover 120 enclose an air outlet 103. The upper cover 110 includes an air inlet 111, a guide section 112, and an air outlet 113 near the air outlet 103. The height of the air inlet 111 is greater than the height of the air outlet 113. A groove 101 is provided on the top surface of the air inlet 111. The guide section 112 is connected to the air inlet 111 and the air outlet 113 respectively. The guide section 112 is streamlined, and its height gradually decreases in the air outlet direction.

[0037] Since the air inlet 111 is at a higher height than the air outlet 113, the air inlet chamber is relatively larger, which can increase the volume of air intake at one time. The airflow is guided by the guide section 112 and then flows to the air outlet 103. The streamlined design also minimizes wind noise.

[0038] In some embodiments, such as Figure 1 and Figure 6 As shown, a handle 150 is provided on the rear side of the fan body 100, which allows the user to lift the entire fan for easy transport. Supports 160 are provided on both sides of the handle 150, allowing the user to place the entire fan vertically with the air outlet 103 facing upwards, supported by the supports 160 to meet the user's need for upward airflow.

[0039] Furthermore, a vibration damping pad 161 is fixed to the rear side of the support platform 160. The vibration damping pad 161 can reduce the vibration transmission of the placement surface, so that the entire fan can be placed stably vertically, and also helps to reduce noise.

[0040] In some embodiments, such as Figure 1 and Figure 7 As shown, the left and right sides of the fan body 100 are provided with support planes 170. Users can place the entire fan on its side, and the support planes 170 can contact the placement surface to stably support the entire fan through the flat support planes 170.

[0041] The terms and words used in the foregoing description and claims are not limited to their literal meaning, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
