Description

Technical Field

[0001] The utility model relates to a cooling device, in particular to an air supply device for shielding fan blades. Background Art

[0002] In hot weather, in order to achieve the purpose of cooling, a fan has become an essential item in people's lives. The existing fan has a fan wheel with multiple fan blades. The fan wheel is driven by a motor to rotate, and the multiple fan blades drive air flow in an axial inlet and outlet manner. In this way, the fan can send out air flow in a predetermined direction to take away the hot air around the user, thereby achieving the purpose of cooling. However, the fan usually covers the fan wheel with a protective net cover. And in order to avoid the protective net from hindering the driving of air flow, the mesh spacing of the protective net is relatively large. Therefore, users are prone to accidentally touch the rotating fan blades and get injured. Also, the fan usually swings left and right to form a larger air supply range. When swinging in a large range for a long time, it is easy to pull the internal wires, and over time, it is easy to cause the wires to break, and even cause risks such as fires.

[0003] Moreover, in order to drive a large amount of air flow, usually the fan wheel has relatively large radial and axial dimensions. And in order to make the air flow be driven in multiple directions, therefore, the fan will swing at a large angle. In this way, not only will the volume of the fan increase, but it will also occupy a large space when in use. And, a large amount of wind cut noise will be generated when the fan wheel rotates.

[0004] In view of this, there is indeed a need to improve the existing fan. Summary of the Utility Model

[0005] To solve the above problems, the purpose of the utility model is to provide an air supply device, so that the fan blades are not exposed and have a better appearance.

[0006] The secondary purpose of the utility model is to provide an air supply device that can be thinned and generate a large amount of air volume, so as to reduce the space occupied by the air supply device and the wind cut noise.

[0061] To make the above and other objects, features and advantages of the present utility model more obvious and understandable, the following specifically gives the preferred embodiments of the present utility model and makes a detailed description in conjunction with the accompanying drawings; in addition, the same symbols marked in different drawings are regarded as the same and their descriptions will be omitted.

[0062] Please refer to Figure 1 , Figure 2 As shown, it is the first embodiment of the air supply device of the present utility model, including a housing body 1 and several air flow driving members 2, and the several air flow driving members 2 are located in the housing body 1.

[0063] The housing body 1 has a base 11, and the base 11 is used for the air supply device to be stably placed at a predetermined position, and the predetermined position can be, for example, the ground or a tabletop. The base 11 can have a relatively large bottom area (i.e., the area in contact with the predetermined position) so that the air supply device is not easily toppled. The housing body 1 can have a control panel 1a, and the control panel 1a can have physical buttons, touch buttons, knobs, display interfaces or signal lights, etc. A control unit C can be provided in the housing body 1, and the control unit C is electrically connected to the control panel 1a, so that various functions of the air supply device can be implemented. As can be understood by those skilled in the art, details are not described herein. The present utility model does not limit the setting position of the control panel 1a. In this embodiment, the control panel 1a can be located on the base 11.

[0064] The housing body 1 has an air flow output part 12 for outputting air flow. The air flow output part 12 may have a receiving space S for receiving the plurality of air flow driving members 2. The air flow output part 12 may be formed, for example, by a plate body 12a combined with a frame body 12b, so that the frame body 12b and the plate body 12a surround to form the receiving space S. The frame body 12b may be, for example, a rectangular frame body, a circular frame body or a frame body of other geometric shapes. The air flow output part 12 has an air outlet part 13, and the air outlet part 13 may be an opening formed by the frame body 12b. The air flow output part 12 has a plurality of air inlet parts 14, and the plurality of air inlet parts 14 and the air outlet part 13 are respectively located on opposite sides of the air flow output part 12. The plurality of air inlet parts 14 may be located on the plate body 12a, and the plurality of air inlet parts 14 may be a plurality of through holes. In addition, the above control panel 1a may also be located on the air flow output part 12. For example, the control panel 1a may be located on the frame body 12b.

[0065] In addition, the air flow output part 12 may be directly combined with the base 11. Or, in this embodiment, the air flow output part 12 may be combined with the base 11 through a connecting column 15, so that the air flow output part 12 can be located at an appropriate height. Preferably, the connecting column 15 may have a sleeve part 151 combined with a telescopic part 152, and the telescopic part 152 can be displaced relative to the sleeve 151, so that the air flow output part 12 can be displaced relative to the base 11 for lifting. The sleeve part 151 may be connected to the base 11, and the telescopic part 152 may be connected to the air flow output part 12. Or, in another embodiment, the sleeve part 151 may be connected to the air flow output part 12, and the telescopic part 152 may be connected to the base 11, which is not limited in the present invention. Also, the user can pull the telescopic part 152 to displace relative to the sleeve part 151, and use a fixing member 153 such as a bolt to position the telescopic part 152. Or, the telescopic part 152 can be driven to displace relative to the sleeve part 151 in an electric manner by a linear motor, a hydraulic rod, a pneumatic rod or a gear. In this way, it has the function of enabling the user to appropriately adjust the height position of the air flow output part 12.

[0066] The housing body 1 is provided with a plurality of flow guiding plates 16 which can be located at the air outlet portion 13, and the plurality of flow guiding plates 16 can guide the air flow sent out by the air outlet portion 13 to a predetermined direction. Specifically, the plurality of flow guiding plates 16 are pivotally located at the air outlet portion 13. For example, the plurality of flow guiding plates 16 can be respectively pivotally connected to the openings of the frame body 12b. Each of the plurality of flow guiding plates 16 can be pivotally connected to the upper and lower sides of the frame body 12b so that the plurality of flow guiding plates 16 can swing pivotally left and right. Or, each of the plurality of flow guiding plates 16 can be pivotally connected to the left and right sides of the frame body 12b so that the plurality of flow guiding plates 16 can swing pivotally up and down. Preferably, some of the flow guiding plates 16 can be pivotally connected to the upper and lower sides of the frame body 12b and some of the flow guiding plates 16 can be pivotally connected to the left and right sides of the frame body 12b. In this way, the user can freely adjust the swinging direction of the plurality of flow guiding plates 16 according to needs to guide the air flow sent out by the air outlet portion 13 to a predetermined direction.

[0067] Please refer to Figure 1 、 Figure 5 As shown in the figure, in this embodiment, the housing body 1 is provided with a coupling frame 17 which can have a shape corresponding to the frame body 12b of the air flow output portion 12. The coupling frame 17 has an opening 17a. The coupling frame 17 can be detachably coupled to the frame body 12b by means such as screwing or clamping, so that the opening 17a is aligned with the air outlet portion 13, and the plurality of flow guiding plates 16 are pivotally connected to the opening 17a. In this way, the coupling frame 17 can be disassembled to repair or clean the plurality of flow guiding plates 16. In another embodiment, a linkage rod 18 can be connected to each flow guiding plate 16 (such as Figure 5 ), so that the plurality of flow guiding plates 16 can be pivoted simultaneously through the linkage rod 18. The user can adjust the swinging direction of the plurality of flow guiding plates 16 by, for example, pulling a control handle 181 of the linkage rod 18, which has the effect of better usability.

[0068] In addition, the housing body 1 can be provided with a filter element 19 which can be, for example, a filter screen. The filter element 19 can be adjacent to the plurality of air inlet portions 14. The filter element 19 can be detachably coupled to the frame body 12b by means such as screwing or clamping. In this way, when the outside air enters the air inlet portions 14 through the filter element 19, the filter element 19 can be used to adsorb dust and other particles in the air so that the air outlet portion 13 can output clean air flow. In this embodiment, the frame body 12b has a slot 121 which is adjacent to the plurality of air inlet portions 14. The filter element 19 can be located in the slot 121, so that it is convenient to clean or replace the filter element 19.

[0069] Please refer to Figure 1 、 Figure 3 、 Figure 4As shown in the figure, the several air flow driving members 2 are located in the accommodation space S. Each air flow driving member 2 is respectively opposite to each air inlet portion 14, so that the several air flow driving members 2 can inhale external air through the air inlet portion 14 and output air flow toward the air outlet portion 13. Specifically, each air flow driving member 2 has a fan housing 2a. The fan housing 2a can be integrally formed with the plate body 12a of the air flow output portion 12. Alternatively, the fan housing 2a can be combined with the plate body 12a by locking or clamping. The fan housing 2a has a fan wheel 21. The fan wheel 21 is axially opposite to the air inlet portion 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 air flow, which is not limited in the present utility model. Preferably, each air inlet portion 14 can be blocked by a net member 14a. The net member 14a can be integrally formed with the air inlet portion 14, or combined with the air inlet portion 14 by means of clamping or welding, etc., which is not limited in the present utility model. Through the net member 14a, the passage of air flow can be ensured, and the user can be prevented from accidentally touching the air flow driving member 2.

[0070] When the fan housing 2a is combined with the plate body 12a by locking or clamping, the fan housing 2a can have an opening opposite to the air inlet portion 14 to drive the air flow. In this embodiment, the fan housing 2a and the plate body 12a are integrally formed, that is, the fan housing 2a is formed together when the 12a is formed. The plate body 12a can have several mounting openings 122. The several mounting openings 122 are respectively opposite to the several fan housings 2a to facilitate the installation and maintenance of the fan wheel 21. Each mounting opening 122 can be closed by a closing plate 123 by means of, for example, locking or clamping. At this time, the air inlet portion 14 can be located on the closing plate 123 so that the air inlet portion 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, and then the thickness of the frame body 12b of the air flow output portion 12 can be reduced, thereby generating a larger air volume, and further having the effect of reducing the occupied space and wind cut noise of the air supply device. Preferably, the slot 121 can have a sensing portion 124. The sensing portion 124 can be used to sense whether the filter element 19 is combined with the slot 121. The sensing portion 124 can be electrically connected to the air flow driving member 2. The sensing portion 124 can be, for example, an infrared sensor, a micro switch or a reed switch, etc. When the sensing portion 124 does not detect that the filter element 19 is combined with the slot 121, the sensing portion 124 can control to disconnect the start of the air flow driving member 2. When the sensing portion 124 detects that the filter element 19 is combined with the slot 121, the start of the air flow driving member 2 can be allowed. In this way, the user can be prevented from accidentally touching the rotating fan wheel 21 through each air inlet portion 14 and getting injured.

[0071] Each air flow driving member 2 has an air outlet 22 which can be generally oriented towards the air outlet portion 13 of the air flow output portion 12. The air outlet 22 is communicated with the air inlet portion 14 through an air flow channel R. In this way, whether it is an axial flow fan blade or a centrifugal fan blade, the fan wheel 21 can be driven by the air inlet portion 14 to allow air to enter, and the air can be introduced into the air outlet 22 through the air flow channel R. It should be noted that the air outlet 22 and the fan wheel 21 are not axially aligned, so that the fan wheel 21 is not exposed from the air outlet 22. In this way, it is possible to prevent the user from accidentally touching the fan wheel 21, which has the effect of better safety. In addition, the present utility model does not limit the number and installation positions of the several air flow driving members 2, and workers can, according to requirements, make the air outlets 22 of the several air flow driving members 2 generally cover the air outlet portion 13 to achieve the optimal air outlet efficiency.

[0072] In summary, for the air supply device of the present utility model, since the air flow output portion of the housing body has several air flow driving members, the fan wheel is located inside the air flow driving members and is not exposed, and the user will not accidentally touch the fan wheel and get injured, so that the effects of better appearance and better use safety can be achieved. In addition, by forming a lower axial thickness for each air flow driving member, the thickness of the housing of the air flow output portion can be further reduced, and a larger air volume can be generated, achieving the effects of reducing the occupied space and wind cut noise of the air supply device.
