Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to a cross-flow fan and a disinfection device. Background Technology

[0002] Crossflow fans, also known as cross-flow fans, are widely used in various electrical equipment because they can produce a flat, uniform and wide airflow. The basic structure of a crossflow fan usually includes a volute, a fan wheel placed inside the volute, a drive motor that drives the fan wheel to rotate, and a mounting bracket for fixing the drive motor.

[0003] In current mainstream designs, the mounting bracket includes a vertical rod and a first and a second horizontal plate connected to both ends of the vertical rod. The first horizontal plate is locked to the drive motor, and the second horizontal plate has mounting holes. During assembly, the second horizontal plate abuts against the volute housing, and bolts pass through the mounting holes and the volute housing to lock the volute housing and the mounting bracket together. While this design is quite simple, it has a significant drawback: to allow sufficient operating space for tools such as screwdrivers or wrenches when tightening bolts, the vertical rod must be of considerable height. This directly increases the overall axial dimension of the fan, a design that contradicts the current trend of miniaturization and compactness in electrical products.

[0004] Therefore, improvements to existing technologies are necessary. Utility Model Content

[0005] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a cross-flow fan and a disinfection device, which can solve the problem in the current mainstream design of cross-flow fans, where the mounting frame includes a vertical rod and a first horizontal plate and a second horizontal plate at both ends. The motor is connected through the first horizontal plate, and the second horizontal plate abuts against the volute and is locked with bolts. However, in order to leave operating space for the tool to tighten the bolts, the vertical rod needs to be high enough, which increases the overall axial size of the fan, which contradicts the trend of compactness and miniaturization of electrical products.

[0006] A cross-flow fan according to an embodiment of the present invention includes a motor, a volute, and a mounting bracket disposed between the motor and the volute. The volute has a guide hole and a groove on its side plate, the groove communicating with the guide hole.

[0024] Please refer to Figures 2-5According to an embodiment of the present invention, a cross-flow fan includes a motor 30, a volute 10, and a mounting bracket disposed between the motor 30 and the volute 10. A guide hole 13 and a sliding groove 14 are provided on the side plate of the volute 10, and the sliding groove 14 communicates with the guide hole 13. The mounting bracket is disposed between the motor 30 and the volute 10, and includes an L-shaped mounting block, a limiting block 25, and a first mounting plate 23. The L-shaped mounting block has a vertical portion 21 and a horizontal portion 22 that are perpendicular to each other. The limiting block 25 and the horizontal portion 22... The horizontal part 22 is located at the end of the vertical part 21 near the guide hole 13 and matches the shape of the guide hole 13. The first mounting plate 23 is set on the side of the mounting bracket near the motor 30 and is connected to the motor 30. The end of the vertical part 21 away from the horizontal part 22 and the limiting block 25 abut against the motor 30 and the volute 10 respectively. The vertical part 21 passes through the guide hole 13 and can move along the slide groove 14, so that the horizontal part 22 is engaged with the volute 10.

[0025] This invention connects the first mounting plate 23 to the motor 30, and then passes the vertical part 21 of the L-shaped mounting block through the guide hole 13 on the side plate of the volute 10. Since the horizontal part 22 matches the shape of the guide hole 13, it can be smoothly inserted, and the vertical part 21 can move along the connected sliding groove 14. After moving into position, the horizontal part 22 engages with the volute 10, while the end of the vertical part 21 away from the horizontal part 22 and the limiting block 25 respectively abut against the motor 30 and the volute 10, achieving a stable installation. In terms of effectiveness, this design abandons the traditional method of relying on the height of the vertical rod to leave operating space for tools and using bolts for locking. It utilizes the guide hole 13, the sliding groove 14, and the engaging structure to complete the installation, eliminating the need for a large axial operating space and significantly reducing the overall size of the fan 11 in the axial direction, thus conforming to the trend of compactness and miniaturization in electrical products.

[0026] According to some embodiments of the present invention, the first mounting plate 23 has a first through hole 24, the outer casing of the motor 30 has a corresponding first threaded hole, and the fastener passes through the first through hole 24 and is threadedly connected to the first threaded hole to lock the motor 30 and the mounting bracket.

[0027] When installing the motor 30 and the mounting bracket, align the first through hole 24 on the first mounting plate 23 with the first threaded hole on the motor 30 housing. Then, use a fastener (such as a bolt) to pass through the first through hole 24 and screw it into the first threaded hole. Through the engagement of the threads, the motor 30 and the mounting bracket are tightly connected together. This connection method is simple and reliable, and can quickly and securely lock the motor 30 and the mounting bracket together.

[0028] According to some embodiments of the present invention, the outer casing of the motor 30 is fixedly connected with a first fixing block 31 and a second fixing block 32. A first threaded hole is located between the first fixing block 31 and the second fixing block 32. When the first through hole 24 is aligned with the first threaded hole, the first fixing block 31 and the second fixing block 32 respectively abut against the opposite first side and second side of the first mounting plate 23 to jointly restrict the displacement of the first mounting plate 23 in the direction perpendicular to the fastener axis.

[0029] Once the first through hole 24 and the first threaded hole are aligned, the first fixing block 31 and the second fixing block 32 will naturally contact the first and second opposing sides of the first mounting plate 23, respectively. During the tightening of the fasteners, the first fixing block 31 and the second fixing block 32 will always be firmly pressed against the first mounting plate 23 to prevent it from moving in the direction perpendicular to the fastener axis, thus ensuring the relative positional accuracy between the mounting bracket and the motor 30.

[0030] According to some embodiments of the present invention, the cross-flow fan also includes a fan wheel, and the mounting bracket also includes a fixing ring 20. The fan wheel is rotatably housed in the receiving cavity of the volute 10. The outer shell of the motor 30 is provided with a first opening through which its rotating shaft passes, and a second opening is provided on the side plate of the volute 10. The rotating shaft passes through the first opening, the fixing ring 20 and the second opening in sequence and is then connected to the fan wheel for drive.

[0031] When assembling the cross-flow fan, first place the impeller in the receiving cavity of the volute 10 and ensure that it can rotate freely. Then, align the first opening on the housing of the motor 30 with the predetermined direction so that the rotating shaft of the motor 30 passes through the first opening. Pass the rotating shaft through the fixing ring 20 and the corresponding second opening on the side plate of the volute 10 in sequence, and then connect the rotating shaft to the impeller by means of key connection, so that the motor 30 drives the impeller to rotate.

[0032] According to some embodiments of the present invention, the vertical part 21 and the first mounting plate 23 are connected to the outer wall of the fixing ring 20, and the first mounting plate 23 and the horizontal part 22 are respectively disposed on opposite sides of the fixing ring 20 and staggered.

[0033] The first mounting plate 23 and the horizontal part 22 are staggered on both sides of the fixing ring 20 to avoid interference between components, making the installation compact and easy to maintain and repair.

[0034] According to some embodiments of the present invention, the volute 10 further includes an air outlet 12, which is connected to the accommodating cavity. The impeller is used to draw air into the accommodating cavity and discharge it from the air outlet 12.

[0035] When the cross-flow fan is started, the motor 30 drives the impeller to rotate. During the rotation of the impeller, negative pressure is generated, which draws the surrounding air from the air inlet of the volute 10 into the accommodating cavity. The air in the accommodating cavity is accelerated by the action of the impeller and then discharged from the air outlet 12 connected to the accommodating cavity. This achieves directional airflow and can generate a flat, uniform and wide airflow to meet the airflow requirements of various electrical equipment, such as ventilation and heat dissipation.

[0036] According to some embodiments of the present invention, a second mounting plate 15 is connected to the side plate of the volute 10, and the second mounting plate 15 has a second through hole 16.

[0037] When it is necessary to install the cross-flow fan onto other equipment, the second mounting plate 15 on the side plate of the volute 10 can be used to fix the cross-flow fan to other equipment by inserting fasteners (such as bolts) through the second through hole 16.

[0038] Please refer to Figure 1 According to an embodiment of the present invention, a disinfection device includes a heating element and a cross-flow fan. The cross-flow fan has an air outlet 12. The heating element is detachably installed on one side of the air outlet 12 of the cross-flow fan to heat the air discharged from the air outlet 12. The second mounting plate 15 and the second through hole 16 facilitate the installation of the cross-flow fan, enabling it to be easily integrated into different electrical devices, thus improving its versatility and applicability.

[0039] According to some embodiments of the present invention, a second threaded hole is provided on the side plate of the volute 10. The heating component includes a fixed frame, a fixed plate 45 and a heating element 44. The fixed frame is provided with an air inlet and an air outlet, which are parallel to the air outlet 12. An installation hole is provided on the fixed frame. Fasteners pass through the installation hole and are threaded to the second threaded hole to connect the fixed frame and the volute 10. The fixed plate 45 is disposed inside the fixed frame, and the heating element 44 is sleeved on the fixed plate 45.

[0040] The heating element 44 is fitted onto the fixing plate 45, and then the fixing plate 45 with the heating element 44 fitted onto it is placed into the fixing frame. Next, align the mounting holes on the fixed frame with the second threaded holes on the side plate of the volute 10. Then, use fasteners (such as bolts) to pass through the mounting holes and screw them into the second threaded holes, thus tightly connecting the fixed frame and the volute 10. When the cross-flow fan is started, air flows out from the air outlet 12. Since the air inlet and outlet of the fixed frame are parallel to the air outlet 12, the air can pass through the fixed frame along the shortest and smoothest path. When the air flows through the heating element 44 inside the fixed frame, the heating element 44 heats the air, turning the air flowing out of the air outlet 12 into hot air, thereby achieving the heating function.

[0041] According to some embodiments of the present invention, the fixing frame includes a first side panel 40, a second side panel 41, a top plate 42 and a bottom plate 43. The first side panel 40 and the second side panel 41 are each provided with a first fixing groove, a second fixing groove and a third fixing groove. The two ends of the top plate 42 are inserted into the first fixing groove, the two ends of the bottom plate 43 are inserted into the third fixing groove, and the two ends of the fixing plate 45 are inserted into the second fixing groove.

[0042] This plug-in installation method requires no complicated tools or techniques. Operators simply need to insert each component into its corresponding slot in a specific order to assemble the frame. This simple operation reduces installation difficulty and improves installation efficiency.

[0043] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
