Description

Technical Field

[0001] The present application relates to the technical field of air purification, and specifically to an air inlet grille of an air purifier. Background Art

[0002] The air intake grille is a crucial component of an air purifier, with one of its primary functions being air intake. Air enters the air purifier through the grille, undergoing filtration, purification, and other processes before ultimately outputting clean air. The grille also provides protection, preventing large particles of dust, hair, and other foreign matter from entering the air purifier and protecting internal filters and electronic components from becoming clogged or damaged. The design and gap size of the grille control the direction and flow rate of the air inlet and outlet. Proper design can maintain the flow rate within a reasonable range, ensuring that air flows evenly and efficiently through the air purifier, thereby improving purification efficiency.

[0003] Patent No. CN 212253075 U, Hong Kai has developed an air inlet grille for an air purifier, including a grille plate, a support rod, a limit ring and a slag discharge port. The blades are arranged in an annular shape, and the grille holes of an annular structure are formed between the blades to prevent the airflow from entering the air purifier from being evenly blocked by the blades without causing a sharp change in the airflow speed. Therefore, the energy loss and flow resistance of the airflow are relatively small. Therefore, the airflow inlet speed is small and it is not easy to generate large noise. The filter has a certain obstructive effect on the flow rate of the airflow. When the partition exists, the obstructed airflow will move to the area between the filter and the partition and collide with the airflow passing through the grille hole at high speed to form a vortex. Therefore, dust and foreign matter brought in by the airflow are not easily attached to the filter under the action of the vortex. Even if used for a long time, the filter will not be blocked. At the same time, the vortex will discharge pressure through the slag discharge port and send dust and foreign matter into the external filter bag to complete the dust collection and realize the self-cleaning function.

[0004] However, in actual use, it has the following shortcomings:

[0005] Although the annular grille prevents the air flow from changing rapidly and generating noise, the air purifier has multiple gears. As the suction force increases, the size of the pores between the air inlet grilles cannot be adjusted, which leads to an increase in the air flow rate and thus an increase in the noise. In addition, the air flow rate decreases due to the obstruction of the grille, thus affecting the efficiency of air purification. Utility Model Content

[0006] The purpose of this application is to provide an air inlet grille of an air purifier, which solves the problem raised in the background technology that although the annular grille avoids the noise caused by sudden changes in air flow speed, the air purifier has multiple gears. As the suction force increases, the size of the pores between the air inlet grilles cannot be adjusted, which leads to an increase in air flow speed, thereby increasing the noise, and the air flow rate becomes less due to the obstruction of the grille, thereby affecting the efficiency of air purification.

[0007] The grille is mounted on two opposite sides of the frame, and the grille is mounted on two opposite sides of the frame. The grille is mounted on two opposite sides of the frame. The grille is mounted on two opposite sides of the frame. The grille is mounted on two opposite sides of the frame.

[0008] In this technical solution, the grille plate can be slid into the outer frame through the slider, center block and extrusion bolts, and the sliders at both ends of the round rod are aligned with the slide groove, and the center block is aligned with the side groove and the front groove, and then slid in. After reaching the appropriate position, the extrusion bolts are tightened so that the center block is squeezed on the center rod and remains in a fixed state, so that the position and number of the grille plates can be freely set. The angle of each grille plate can be freely adjusted to adapt to the air intake requirements of different gears of the air purifier, reduce the noise of the air intake, and improve the efficiency of air purification. At the same time, the grille plate can be stored through the storage plate below. After the extrusion bolts are loosened, the center block and the slider will slide down. Since the cleaning brush can cover the entire height of the outer frame, no matter how many grille plates are set, they can be cleaned at the same time.

[0009] As an optional solution of the technical solution of the present application, a squeeze bolt is threadedly connected to one side of the front surface of the center block, and one end of the squeeze bolt passes through the center block and contacts the surface of the center rod.

[0010] As an optional solution of the technical solution of the present application, a filter frame is detachably mounted on the surface of the outer frame on the opposite side of the slide groove.

[0011] As an optional solution of the technical solution of the present application, a top plate is detachably mounted on the top end of the outer frame.

[0012] As an optional solution of the technical solution of the present application, a storage plate is fixedly connected to the bottom edge of the outer frame above one side of the slide groove.

[0013] As an optional solution of the technical solution of the present application, the top ends of the side grooves and the front grooves are both located on the top end surface of the center rod, and the top end of the center rod is in contact with the bottom of the top plate.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. This application uses sliders, center blocks and extrusion bolts to slide the grille plate into the outer frame. The sliders at both ends of the round rod are aligned with the slide grooves, the center block is aligned with the side grooves and the front grooves, and then it is slid in. After reaching the appropriate position, the extrusion bolts are tightened so that the center block is squeezed on the center rod and remains fixed, thereby freely setting the position and number of the grille plates. The angle of each grille plate can be freely adjusted to adapt to the air intake requirements of different gears of the air purifier, reduce the noise of the air intake, and improve the efficiency of air purification.

[0016] 2. This application uses the storage plate below to store the grille plates. After the extrusion bolts are loosened, the center block and the slider will slide downward and eventually reach the inner bottom of the outer frame. Several grille plates can be prepared in advance for storage and can be slid on and fixed when needed. This eliminates the need to frequently disassemble the top plate to slide the grille plates in and out, thereby improving the convenience and practicality of the device.

[0017] 3. This application can facilitate the cleaning of the surface of the grille plate through the slide groove, support block, support rod and cleaning brush. The sliding support block moves horizontally with the support rod and cleaning brush, and the cleaning brush will sweep off the dust on the surface of the grille plate. Since the cleaning brush can cover the entire height of the outer frame, no matter how many grille plates are set up, they can all be cleaned at the same time, thereby improving the cleaning efficiency.

[0025] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, they are further elaborated below in conjunction with specific implementation methods.

[0026] like Figure 1 As shown, an air inlet grille of an air purifier includes an outer frame 1, a round rod 10, a center rod 2 and a grille plate 15. A slide groove 501 is provided below the surface of the frame 1. A support block 5 is slidably connected to the inner side of the slide groove 501. The top of the support block 5 is fixedly connected to the support rod 6. The top of the outer frame 1 is detachably mounted with a top plate 3.

[0027] like Figure 2 As shown, a filter frame 4 is detachably mounted on the surface of the outer frame 1 on the opposite side of the slide 501, and a storage plate 16 is fixedly connected to the inner bottom edge of the outer frame 1 above one side of the slide 501. The filter frame 4 can be removed for cleaning, and the storage plate 16 can cover and store the unused grille plate 15 to prevent dust from adhering to its surface.

[0028] like Figure 1 and Figure 3As shown, a center rod 2 is vertically fixedly connected to the center of the inner bottom of the outer frame 1, a side groove 14 is opened through the side wall of the center rod 2, and a front groove 13 is vertically opened on the front surface of the center rod 2, and the front groove 13 is connected to the side groove 14. The center block 11 is vertically slidably connected on the inner side of the side groove 14 and the front groove 13. An extrusion bolt 12 is threadedly connected to one side of the front surface of the center block 11. One end of the extrusion bolt 12 passes through the center block 11 and contacts the surface of the center rod 2. After the extrusion bolt 12 is tightened, the center block 11 will be tightly squeezed against the surface of the center rod 2, thereby maintaining a fixed state.

[0029] like Figure 3 As shown, the top ends of the side grooves 14 and the front grooves 13 are both located on the top surface of the center rod 2, making it convenient to slide in and out of the center block 11 from above. The top end of the center rod 2 is in contact with the bottom of the top plate 3, and after being removed, the side grooves 14 and the front grooves 13 can be exposed.

[0030] like Figure 1 and Figure 4 As shown, a cleaning brush 7 is fixedly connected to the surface of the support rod 6 facing the grille plate 15, and vertical grooves 8 are vertically opened on the left and right inner walls of the outer frame 1. The cleaning brush 7 can cover the inner side of the outer frame, thereby cleaning multiple grille plates 15 at the same time.

[0031] like Figure 5 As shown, both ends of the round rod 10 are fixedly connected with sliders 9, and the sliders 9 are vertically slidably connected on the inner side of the vertical groove 8. Grille plates 15 are passed through and fixedly connected on both sides of the surface of the round rod 10, and a center block 11 is passed through and movably connected to the center of the surface of the round rod 10. The center block 11 fits tightly with the round rod 10, and both surfaces have relatively large friction, so it can play a partial limiting role when rotating the grille plate 15.

[0032] In actual use, the top plate 3 can be disassembled from the top of the outer frame 1, so that the vertical slots 8 on both sides and the front slot 13 and side slots 14 on the surface of the center rod 2 are exposed, and the sliders 9 at both ends of the round rod 10 are aligned with the slide slot 501, and the center block 11 is aligned with the side slots 14 and the front slot 13, and then slides in. After reaching the appropriate position, the extrusion bolts 12 are tightened so that the center block 11 is squeezed on the center rod 2 and remains in a fixed state, thereby freely setting the position and number of the grille plates 15. The angle of each grille plate 15 can be freely adjusted to adapt to the air intake requirements of different gears of the air purifier, reduce the noise of the air intake, and improve the efficiency of air purification. The extrusion bolts After 12 is loosened, the center block 11 and the slider 9 will slide downward and eventually reach the inner bottom of the outer frame 1. Several grille plates 15 can be prepared and stored in advance, and can be slid on to be fixed when needed. There is no need to frequently disassemble the top plate 3 to slide the grille plates 15 in and out, which improves the convenience and practicality of the device. The sliding support block 5 moves horizontally with the support rod 6 and the cleaning brush 7, and the cleaning brush 7 sweeps the dust off the surface of the grille plates 15. Since the cleaning brush 7 can cover the entire height of the outer frame 1, no matter how many grille plates 15 are set, they can be cleaned at the same time, thereby improving the cleaning efficiency.
