Description

Technical Field

[0001] This utility model relates to the field of air guide grille technology, specifically to a ventilator outlet with an adjustable air guide grille. Background Technology

[0002] A ventilator is a machine that uses input mechanical energy to increase gas pressure and discharge gas. It is a type of driven fluid machinery. Modern ventilators are widely used in factories, mines, tunnels, cooling towers, vehicles, ships and buildings for ventilation, dust removal and cooling, as well as for grain drying and conveying. In order to adapt to the needs of different ventilation angles, a ventilator outlet with an adjustable air guide grille is required.

[0003] The prior art patent document with publication number CN210373827U provides an air conditioner outdoor unit with an adjustable air outlet grille, including an air conditioner outdoor unit body, a horizontal adjustment unit and a vertical adjustment unit. The horizontal adjustment unit includes a first motor support frame, a first motor, a first rotating shaft, a first pulley, a first belt and a horizontal grille. The first motor and the second motor drive the horizontal grille and the vertical grille to rotate respectively, thereby achieving the purpose of adjusting the air outlet in the horizontal and vertical directions. A microcontroller and a signal receiver are also provided. The signal receiver receives signals and sends them to the microcontroller. The microcontroller then processes the signals and controls the second motor and the first motor to work, which can easily adjust the air outlet direction of the air conditioner outdoor unit.

[0004] Although the device has many beneficial effects, the following problems still exist: During the use of the device, the grid plate is fixedly connected to the rotating shaft, making it inconvenient to disassemble for cleaning. After long-term use, dust accumulation on the grid plate can easily cause pollution during ventilation. Secondly, during the use of the device, the motor drives the rotating shaft to rotate, which in turn rotates the grid plate to adjust the air guide angle. It is inconvenient to lock, and the angle of the grid plate can easily change due to wind force during ventilation, affecting its use. Improvements are needed. In view of this, we propose a ventilator outlet with an adjustable air guide grid. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments.

[0006] 1. Technical problems to be solved:

[0007] To address the issues mentioned above, such as the fixed connection between the central grid plate and the rotating shaft making disassembly for cleaning inconvenient, the accumulation of dust on the grid plate after long-term use leading to pollution during ventilation, and the inconvenience of locking the grid plate due to the motor-driven rotating shaft adjusting the air guide angle, which can easily cause the grid plate to change angle due to wind force during ventilation, this utility model is proposed.

[0008] Therefore, the purpose of this utility model is to provide a ventilator outlet with an adjustable air guide grille, which facilitates the removal of the grille for cleaning, avoids dust accumulation on the grille surface causing pollution during ventilation, facilitates locking the rotation angle of the grille, prevents the grille from changing its angle due to wind force during ventilation, and is convenient to use.

[0011] A ventilator outlet with an adjustable air guide grille includes a frame. Multiple grille plates are rotatably connected to the bottom of the frame's inner cavity. An electric push rod is located on the side wall of the frame, and a linkage rod is located at the output end of the electric push rod. An installation assembly is located on the outer circumference of the linkage rod. The installation assembly includes multiple fixing blocks, each with a connecting seat on its side wall.

A moving plate is located at the other end of each first spring, and multiple positioning shafts are located on the top of the moving plate. A locking assembly is located on the side wall of the frame's inner cavity. The electric push rod is electrically connected to an external power source. The inner diameter of the ball groove outlet is smaller than the diameter of the inner circumference of the ball groove to prevent the positioning ball from detaching from the ball groove.

[0012] As a preferred embodiment of the present invention, a ventilator outlet with an adjustable air guide grille is provided, wherein the locking assembly includes a fixing frame, electromagnets are provided on both sides of the top of the fixing frame, a friction cylinder is provided at one end of the outer circumference of the linkage rod, a fixing plate is provided on the inner cavity side wall of the frame, a second spring is provided on both sides of the bottom of the fixing plate, a moving block is provided at the bottom of the second spring, and a friction ring is provided on the side wall of the moving block. The electromagnets are electrically connected to an external power source. The fixing frame is recessed downward in the middle to prevent the fixing frame from obstructing the movement of the friction cylinder with the linkage rod.

[0013] As a preferred embodiment of the present invention, the number and position of the screws are matched with the number and position of the grille plates, and the screws are threadedly connected to the side wall of the grille plates.

[0014] In a preferred embodiment of the present invention, a ventilator outlet with an adjustable air guide grille is provided, wherein both ends of the movable plate protrude through the sidewalls of the frame, and both ends of the bottom of the movable plate are provided with support blocks.

[0018] 3. Beneficial effects:

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] The air outlet of this type of ventilator with adjustable air guide grille can be manually pushed to move the moving plate, causing the positioning shaft to disengage from the connecting groove.

[0033] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0034] This utility model provides an overall structural schematic diagram of an embodiment of a ventilator outlet with an adjustable air guide grille, including:

[0035] Please see Figures 1-5 This embodiment provides a ventilator outlet with an adjustable air guide grille, comprising a frame 1. Multiple grille plates 2 are rotatably connected to the bottom of the inner cavity of the frame 1. The grille plates 2 guide the air outlet angle of the ventilator. An electric push rod 3 is threadedly connected to the side wall of the frame 1. A linkage rod 4 is threadedly connected to the output end of the electric push rod 3. The electric push rod 3 drives the linkage rod 4 to move, causing the multiple grille plates 2 to rotate synchronously. An installation assembly 5 is interference-fitted to the outer circumference of the linkage rod 4. The installation assembly 5 includes multiple fixing blocks 501. Connecting seats 502 are welded to the side walls of each fixing block 501. A ball groove 503 is formed on the side wall of the connecting seat 502. A positioning ball 504 is rotatably connected to the inner circumference of the ball groove 503. The ball groove 503 allows the positioning ball 504 to rotate freely, preventing the grille plates 2 from rotating. This causes the connection with the linkage rod 4 to jam. A screw 505 is welded to one side of the outer circumference of the positioning ball 504. The screw 505 is for threaded connection with the grid plate 2 for easy disassembly and assembly. The top and bottom of the grid plate 2 are provided with connecting grooves 506. Multiple first springs 507 are welded to the inner cavities of the top and bottom of the frame 1. A moving plate 508 is welded to the other end of the first spring 507. The first spring 507 is for rebound to drive the moving plate 508 to move, thereby moving the positioning shaft 509. Multiple positioning shafts 509 are welded to the top of the moving plate 508. The positioning shafts 509 are for inserting into the connecting grooves 506 for rotational connection, limiting the position of the grid plate 2 to prevent it from falling off, and facilitating the disassembly and assembly of the grid plate 2 for cleaning. A locking component 6 is welded to the inner cavity side wall of the frame 1. The electric push rod 3 is electrically connected to an external power source.

[0036] It is worth noting that, in order to facilitate locking the angle of the grille plate 2, the locking assembly 6 specifically includes a fixing frame 601. Electromagnets 602 are glued to both sides of the top of the fixing frame 601. A friction cylinder 603 is welded to one end of the outer circumference of the linkage rod 4. A fixing plate 604 is welded to the inner wall of the frame 1. A second spring 605 is welded to both sides of the bottom of the fixing plate 604. The second spring 605 is used to rebound and drive the moving block 606 to move upward and reset, so as to prevent the friction ring 607 from obstructing the movement of the linkage rod 4 when adjusting the air guide angle. A moving block 606 is welded to the bottom of the second spring 605. The moving block 606 is used to attract and drive the friction ring 607 downward after the electromagnet 602 conducts electricity. A friction ring 607 is welded to the side wall of the moving block 606. The friction ring 607 is used to fit tightly with the friction cylinder 603 for friction locking, so as to prevent the movement of the linkage rod 4 from causing the grille plate 2 to rotate and affect the air guide direction. The electromagnet 602 is electrically connected to an external power source.

[0037] Next, in order to facilitate the synchronous rotation of multiple grille plates 2, the number and position of screws 505 are matched with the number and position of grille plates 2. The screws 505 are threadedly connected to the side wall of the grille plate 2. By using screws 505 that match the number and position of grille plates 2, it is easy to make multiple grille plates 2 rotate synchronously to adjust the ventilation angle.

[0038] Meanwhile, to facilitate single-person operation when disassembling the grating plate 2, specifically, both ends of the movable plate 508 protrude through the side wall of the protruding frame 1, and both ends of the bottom of the movable plate 508 are engaged with support blocks 510. Through the movable plate 508 that protrudes through the side wall of the protruding frame 1, it is convenient for the staff to manually pull the edge of the movable plate 508 to move it. The support blocks 510 can be inserted into the top edge of the movable plate 508 after the movable plate 508 has moved, so that the position of the movable plate 508 remains unchanged, which facilitates the movement of the other movable plate 508 and facilitates single-person operation to disassemble the grating plate 2.

[0039] Furthermore, to facilitate stable locking of the linkage rod 4, specifically, the friction cylinder 603 is slidably connected to the side wall of the frame 1. The size and position of the friction cylinder 603 match the size and position of the friction ring 607. The slidable connection between the friction cylinder 603 and the side wall of the frame 1 prevents the side wall of the frame 1 from blocking the movement of the linkage rod 4. The friction cylinder 603, which matches the size and position of the friction ring 607, makes it easier for the friction cylinder 603 and the friction ring 607 to fit more tightly, thereby increasing the friction and making the locking more stable.

[0040] It is worth noting that, in order to facilitate the control of the moving block 606 by magnetic attraction, specifically, the friction cylinder 603 and the friction ring 607 are both made of copper-based powder metallurgy material, and the moving block 606 is made of 340 stainless steel. The friction cylinder 603 and the friction ring 607, made of copper-based powder metallurgy material, have good wear resistance and long service life, and are non-magnetic and will not be attracted by the electromagnet 602 and cause interference. The moving block 606, made of 340 stainless steel, is protected from corrosion and can be attracted by the electromagnet 602 to move.

[0041] Finally, in order to limit the smooth movement of the friction ring 607, specifically, the bottom of the fixed plate 604 is slidably connected to the connecting rods 608 located on the top of the moving block 606. The top of the outer circumference of the two connecting rods 608 is welded with limit rings 609. The connecting rods 608 help to limit the movement of the moving block 606 and prevent the friction ring 607 from tilting and affecting the locking of the friction cylinder 603. The limit rings 609 help to limit the connecting rods 608 to prevent them from disengaging.

[0042] In addition, the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. Furthermore, the scope of protection of this utility model does not involve improvements to the internal structure and methods.

[0043] The device or equipment models mentioned in this article may be as follows:

[0044] Electric linear actuator 3: LAM33-B.

[0045] Combination Figures 1-5 The specific usage process of a ventilator outlet with an adjustable air guide grille according to this embodiment is as follows:

[0046] 1. When this device is needed for use at the air outlet of a ventilator with an adjustable air guide grille, connect the frame 1 to the air outlet of the ventilator by thread. Start the electric push rod 3 to move the linkage rod 4, which causes the fixed block 501 to move the connecting seat 502. This causes the positioning ball 504 to rotate in the ball groove 503, which in turn causes the grille plate 2 at one end of the screw 505 to rotate and adjust the air outlet angle. After long-term use, pull out the support block 510, manually push the moving plate 508 to move so that the positioning shaft 509 is disengaged from the connecting groove 506. Insert the support block 510 into the top edge of the moving plate 508 to keep the position of the moving plate 508 unchanged. Repeat the operation for the other moving plate 508. Manually turn the screw 505 to disengage the grille plate 2 from the screw 505. Remove the grille plate 2 separately for cleaning.

[0047] 2: When it is necessary to stop the rotation of the grille plate 2 and fix the air guide angle, control the electromagnet 602 to conduct electricity, so that the electromagnet 602 attracts the moving block 606 to move downward, causing the friction ring 607 to fit tightly with the friction cylinder 603 for friction locking. When it is necessary to adjust the rotation angle of the grille plate 2, the electromagnet 602 is de-energized, the second spring 605 rebounds and causes the moving block 606 to move upward and reset, so that the friction ring 607 moves away from the friction cylinder 603.

[0048] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
