Description

Technical Field

[0001] This invention relates to a cooling device, and more particularly to an air supply device that shields fan blades. Background Technology

[0002] In hot weather, fans have become essential household items for cooling. Existing fans have a fan wheel with multiple blades. The fan wheel is driven to rotate by a motor, and the blades drive airflow in an axial-to-axial manner. This allows the fan to deliver airflow in a predetermined direction to remove heat from the user's surroundings, thus achieving cooling. However, these fans typically use a protective net to cover the fan wheel, and to prevent the net from obstructing airflow, the mesh has large gaps. Therefore, users can easily touch the rotating blades and get injured. Furthermore, these fans usually create a large airflow range by oscillating left and right. Prolonged oscillation of this large range can strain the internal wiring, potentially leading to wire breakage or even a fire hazard.

[0003] Moreover, in order to drive a large amount of airflow, the fan wheel usually has a large radial and axial dimension, and in order to drive the airflow in multiple directions, the fan will oscillate at a large angle. As a result, the fan will not only increase in size and occupy a large space when in use, but also generate a lot of wind shear noise when the fan wheel rotates.

[0004] Therefore, there is indeed a need to improve the existing fans. Summary of the Invention

[0005] To address the aforementioned problems, the present invention aims to provide an air supply device that allows the fan blades to be partially concealed, resulting in a better appearance.

[0006] A secondary objective of the present invention is to provide an air supply device that can be made thin and generate a large air volume, thereby reducing the space occupied by the air supply device and the wind shear noise.

[0007] The directions or similar terms used throughout this invention, such as "front," "back," "left," "right," "top," "bottom," "inner," "outer," and "side," are mainly for reference to the directions in the accompanying drawings. These directions or similar terms are only used to assist in explaining and understanding the various embodiments of this invention and are not intended to limit this invention.

[0008] The use of the quantifiers “a” or “an” for the elements and components described throughout this invention is for convenience and to provide the general meaning of the scope of the invention; in this invention, it should be interpreted as including one or at least one, and a single concept also includes multiple cases, unless it clearly means otherwise.

[0009] The terms "combination," "integration," or "assembly" used throughout this invention mainly refer to forms such as those in which the components can be separated without damaging them after connection, or those in which the components cannot be separated after connection. Those skilled in the art can choose the appropriate term based on the material of the components to be connected or the assembly requirements.

[0010] The air supply device of the present invention includes: a housing body having an airflow output section having an accommodating space, the airflow output section having an air outlet and a plurality of air inlets facing each other; and a plurality of airflow driving members located in the accommodating space of the airflow output section, each airflow driving member having a fan wheel, the fan wheel of each airflow driving member being respectively located in each air inlet, each airflow driving member having an air outlet facing the air outlet of the airflow output section, the air outlet being connected to the air inlets through an airflow channel.

[0011] Therefore, the air supply device of the present invention has several airflow drive members in the airflow output section of the housing body. The fan wheel is located inside the airflow drive members and is not exposed, so the user will not accidentally touch the fan wheel and be injured. This achieves the effects of better appearance and better safety in use. In addition, by forming a low axial thickness by each airflow drive member, the thickness of the frame of the airflow output section can be further reduced, and a larger air volume can be generated, thereby reducing the space occupied by the air supply device and the wind shear noise.

[0012] The air outlet and the fan wheel are not axially aligned. This prevents the fan wheel from being exposed at the air outlet.

[0013] The casing has a base, and the airflow outlet is connected to the base via a connecting post. The connecting post has a sleeve portion, which is connected to a telescopic portion in a relatively displaced manner, allowing the airflow outlet to move relative to the base. This allows the user to adjust the height of the airflow outlet as needed.

[0014] The connecting column includes a fixing member for positioning the telescopic part. This allows the airflow outlet to be fixed at an appropriate height.

[0015] The airflow outlet includes a plate and a frame, which surround the plate to form the accommodating space. The air outlet is an opening formed by the frame, and the plurality of air inlets are located on the plate. In this way, by combining the frame and the plate to form the airflow outlet, the airflow outlet can be made thinner, thereby improving its appearance.

[0016] The shell body has several guide vanes located at the air outlet. These guide vanes effectively guide the airflow from the outlet in a predetermined direction.

[0017] The housing body has a connecting frame with an opening located at the air outlet, and the plurality of air deflectors are pivotally connected to the opening. This allows for the disassembly of the connecting frame for maintenance or cleaning of the air deflectors.

[0018] A linkage connects each deflector plate. This linkage allows for the simultaneous pivoting of several deflectors plates.

[0019] The housing body includes a filter element adjacent to the plurality of air inlets. This allows the air outlet to output clean airflow.

[0020] The housing body has a slot adjacent to the plurality of air inlets, and the filter element is located in the slot. This allows the filter element to be positioned within the slot for easy cleaning or replacement.

[0021] The slot includes a sensor to detect whether the filter is located within it. This prevents users from accidentally touching the rotating fan wheel through the air inlets and getting injured.

[0022] Each airflow drive component has a fan housing, which is integrally formed with the plate of the airflow output section. This further reduces the axial thickness of each fan housing, thereby reducing the space occupied by the air supply device and the wind shear noise.

[0023] The plate has several mounting ports, which are respectively located on several fan housings. Several sealing plates are detachably connected to each mounting port, and each air inlet is located on each sealing plate. This facilitates the installation and maintenance of the fan wheel.

[0024] Each air inlet section has a mesh screen. This mesh screen ensures airflow and prevents the user from accidentally activating the airflow drive mechanism. Attached Figure Description

Detailed Implementation

[0027] To make the above and other objects, features and advantages of the present invention more apparent and understandable, preferred embodiments of the present invention are described below in detail with reference to the accompanying drawings; in addition, those symbols that are used in different drawings are considered to be the same and their descriptions will be omitted.

[0028] Please refer to Figure 1 , Figure 2 As shown, it is the first embodiment of the air supply device of the present invention, which includes a shell body 1 and several airflow driving components 2, the several airflow driving components 2 being located in the shell body 1.

[0029] The housing body 1 has a base 11 for stably placing the air supply device at a predetermined position, such as the ground or a tabletop. The base 11 may have a relatively large bottom area (i.e., the area in contact with the predetermined position) to prevent the air supply device from tipping over. The housing body 1 may have a control panel 1a, which may include physical buttons, touch buttons, knobs, a display interface, or indicator lights to perform various functions of the air supply device. These features are well understood by those skilled in the art and will not be described in detail here. This invention does not limit the location of the control panel 1a; in this embodiment, the control panel 1a may be located on the base 11.

[0030] The housing body 1 has an airflow outlet 12 for outputting airflow. The airflow outlet 12 may have a receiving space S for accommodating the plurality of airflow driving members 2. The airflow outlet 12 may be formed, for example, by a plate 12a combined with a frame 12b, such that the frame 12b and the plate 12a surround to form the receiving space S. The frame 12b may be, for example, a rectangular frame, a circular frame, or a frame of other geometric shapes. The airflow outlet 12 has an air outlet 13, which may be an opening formed by the frame 12b. The airflow outlet 12 has a plurality of air inlets 14, which are located on opposite sides of the airflow outlet 12, respectively. The air inlets 14 may be located on the plate 12a and may be a plurality of through holes. In addition, the control panel 1a can also be located in the airflow output section 12, for example, the control panel 1a can be located in the frame 12b.

[0031] Furthermore, the airflow output section 12 can be directly connected to the base 11, or, in this embodiment, the airflow output section 12 can be connected to the base 11 via a connecting post 15, so that the airflow output section 12 can be positioned at an appropriate height. Preferably, the connecting post 15 can have a sleeve section 151, which is connected to a telescopic section 152. The telescopic section 152 can be displaced relative to the sleeve 151, so that the airflow output section 12 can be displaced relative to the base 11 for raising and lowering. The sleeve section 151 can be connected to the base 11, and the telescopic section 152 can be connected to the airflow output section 12. Alternatively, in another embodiment, the sleeve section 151 can be connected to the airflow output section 12, and the telescopic section 152 can be connected to the base 11; this invention is not limited thereto. Furthermore, the user can pull the telescopic section 152 to displace it relative to the sleeve 151, and position the telescopic section 152 with a fastener 153, such as a bolt. Alternatively, the telescopic part 152 can be electrically displaced relative to the sleeve 151 by means of a linear motor, hydraulic rod, pneumatic rod, or gear. This allows the user to adjust the height of the airflow outlet 12 as needed.

[0032] The shell body 1 has several guide vanes 16, which can be located in the air outlet 13. These guide vanes 16 can guide the airflow from the air outlet 13 to a predetermined direction. Specifically, the guide vanes 16 can be pivotally located in the air outlet 13. For example, the guide vanes 16 can be pivotally connected to the opening of the frame 12b, and each guide vane 16 can be pivotally connected to the upper and lower sides of the frame 12b, allowing the guide vanes 16 to pivot left and right. Alternatively, each guide vane 16 can be pivotally connected to the left and right sides of the frame 12b, allowing the guide vanes 16 to pivot up and down. Preferably, some guide vanes 16 can be pivotally connected to the upper and lower sides of the frame 12b, and some guide vanes 16 can be pivotally connected to the left and right sides of the frame 12b. In this way, the user can freely adjust the swing direction of the several deflectors 16 as needed to guide the airflow delivered by the air outlet 13 to a predetermined direction.

[0033] Please refer to Figure 1 , Figure 5 As shown, in this embodiment, the shell body 1 has a connecting frame 17, which may have a shape corresponding to the frame 12b of the airflow outlet 12. The connecting frame 17 has an opening 17a, and the connecting frame 17 can be detachably connected to the frame 12b by means of, for example, screwing or snapping, so that the opening 17a is aligned with the air outlet 13. The plurality of guide plates 16 are pivotally connected to the opening 17a. Thus, the connecting frame 17 can be disassembled to allow for maintenance or cleaning of the plurality of guide plates 16. In another embodiment, a linkage 18 can connect each guide plate 16 (e.g., Figure 5 Thus, the linkage 18 can simultaneously pivot the multiple deflectors 16, and the user can adjust the swing direction of the multiple deflectors 16 by, for example, turning a control handle 181 of the linkage 18, which has the effect of better ease of use.

[0034] Furthermore, the housing body 1 may have a filter element 19, which may be, for example, a filter screen. The filter element 19 may be adjacent to the plurality of air inlets 14 and may be detachably attached to the frame 12b by means of, for example, screwing or snapping. Thus, when outside air enters the air inlet 14 through the filter element 19, the filter element 19 can adsorb dust and other particles in the air, allowing the air outlet 13 to output clean airflow. In this embodiment, the frame 12b has a slot 121 adjacent to the plurality of air inlets 14, and the filter element 19 may be located in the slot 121, thus facilitating cleaning or replacement of the filter element 19.

[0035] Please refer to Figure 1 , Figure 3 , Figure 4 As shown, the plurality of airflow drive components 2 are located in the accommodating space S, and each airflow drive component 2 is respectively located opposite to the air inlet 14, so that the plurality of airflow drive components 2 can draw in outside air through the air inlet 14 and output airflow toward the air outlet 13. Specifically, each airflow drive component 2 has a fan housing 2a, which can be integrally formed with the plate 12a of the airflow outlet 12, or the fan housing 2a can be locked or snapped together with the plate 12a. The fan housing 2a has a fan wheel 21, which is axially opposite to the air inlet 14. The fan wheel 21 can be driven to rotate by a motor, for example, the fan wheel 21 can be driven to rotate by direct current or alternating current. The fan wheel 21 can be an axial flow fan blade or a centrifugal fan blade to drive the airflow, and the present invention is not limited thereto. Preferably, each air inlet 14 can be shielded by a mesh 14a. The mesh 14a can be integrally formed on the air inlet 14, or it can be attached to the air inlet 14 by means of snap-fitting or welding, etc. The present invention is not limited thereto. The mesh 14a can ensure the passage of airflow and prevent the user from accidentally touching the airflow drive component 2.

[0036] When the fan housing 2a is locked or snapped onto the plate 12a, the fan housing 2a can have an opening at the air inlet 14 to drive airflow. In this embodiment, the fan housing 2a and the plate 12a are integrally formed, that is, the fan housing 2a is formed at the same time as the plate 12a. The plate 12a can have several mounting ports 122, which are respectively located on the several fan housings 2a to facilitate the installation and maintenance of the fan wheel 21. Each mounting port 122 can be closed by a sealing plate 123 by means of locking or snapping. At this time, the air inlet 14 can be located on the sealing plate 123 so that the air inlet 14 can be axially aligned with the fan wheel 21. In this way, the axial thickness of each fan housing 2a can be further reduced, thereby reducing the thickness of the frame 12b of the airflow output section 12, thereby generating a larger air volume, and thus reducing the space occupied by the air supply device and the wind shear noise. Preferably, the slot 121 may have a sensing unit 124, which can sense whether the filter 19 is engaged in the slot 121. The sensing unit 124 may be electrically connected to the airflow drive 2, and may be, for example, an infrared sensor, a micro switch, or a reed switch. When the sensing unit 124 does not detect that the filter 19 is engaged in the slot 121, the sensing unit 124 can control the disconnection of the airflow drive 2. When the sensing unit 124 detects that the filter 19 is engaged in the slot 121, the airflow drive 2 can be allowed to start. In this way, the user can be prevented from being injured by accidentally touching the rotating fan wheel 21 through the air inlets 14.

[0037] Each airflow drive component 2 has an air outlet 22, which is generally oriented towards the air outlet 13 of the airflow output section 12. The air outlet 22 is connected to the air inlet section 14 through an airflow channel R. Thus, regardless of whether it is an axial or centrifugal fan blade, the fan wheel 21 can be driven by the air inlet section 14 to enter, and the airflow is guided to the air outlet 22 through the airflow channel R. It is worth noting that the air outlet 22 and the fan wheel 21 are not axially aligned, so that the fan wheel 21 is not exposed by the air outlet 22. This can prevent the user from accidentally touching the fan wheel 21, providing better safety. In addition, the present invention does not limit the number or the arrangement of the airflow drive components 2. The manufacturer can arrange the air outlets 22 of the airflow drive components 2 to generally cover the air outlet 13 as needed to achieve the optimal airflow efficiency.

[0038] In summary, the air supply device of the present invention has several airflow drive members in the airflow output section of the housing body. The fan wheel is located inside the airflow drive members and is not exposed, so the user will not accidentally touch the fan wheel and cause injury. This achieves the effects of better appearance and better safety in use. In addition, by forming a low axial thickness by each airflow drive member, the thickness of the frame of the airflow output section can be further reduced, and a larger air volume can be generated, thereby reducing the space occupied by the air supply device and the wind shear noise.

Any modifications and alterations made by those skilled in the art to the above embodiments without departing from the spirit and scope of the present invention shall still fall within the technical scope protected by the present invention.
