Description

Technical Field

[0001] This utility model relates to the field of air purification equipment technology, and in particular to a purifier that supports multi-angle air intake and exhaust. Background Technology

[0002] With increasing attention to air pollution and rising demand for a healthy living environment, air purifiers have become common equipment in homes, offices, and other indoor environments. Existing air purifiers typically use a built-in fan to drive airflow, allowing indoor air to pass through an internal filter for purification before being discharged.

[0003] Traditional air purifiers typically employ a separate airflow channel design, meaning that the air inlet and outlet are set up independently and each is equipped with a dedicated grille structure. This design requires the air inlet and outlet grilles to be designed and installed independently, resulting in a complex outer shell structure, reduced internal space utilization, and increased production costs. In addition, if multi-angle coverage of the air inlet and outlet is required at the same time, two independent grille systems must be adjusted separately, which is cumbersome and difficult to optimize in coordination. Utility Model Content

[0004] The purpose of this invention is to provide an air purifier that supports multi-angle air intake and exhaust, enabling efficient and uniform intake of air to be purified from multiple angles of space, and uniform delivery of purified air back into the indoor space in a non-directional and diffused manner, thereby significantly improving purification efficiency, eliminating purification dead zones, improving user experience, and having the advantages of simple structure and high space utilization.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a purifier that supports multi-angle air intake and exhaust, comprising a purifier body, a purification component disposed inside the purifier body, a grid structure covering the outer surface of the purifier body, the grid structure having an air intake area and an air exhaust area spaced apart along the vertical direction, the grid structure including at least two sets of grid plates with different orientations, the grid plates allowing external airflow to be drawn into the purifier body from the air intake area at multiple angles, and the purified airflow to diffuse outward from the air exhaust area at multiple angles.

[0006] By adopting the above technical solution, multi-angle air intake and exhaust can be achieved using a single independent grille structure, which not only eliminates purification dead corners and improves purification efficiency, but also avoids setting up two separate grille structures for air intake and exhaust, saving production costs and optimizing equipment space utilization.

[0007] A further feature of this invention is that: a top plate is provided above the main body of the purifier, and a base is provided below it; the grille structure is located between the top plate and the base; a control panel is provided between the top plate and the base; and the control panel is fixedly connected to the grille structure.

[0008] By adopting the above technical solution, it is possible to avoid setting up two sets of grille structures for air intake and exhaust, thereby saving production costs, optimizing the space utilization of the equipment, and making the overall appearance symmetrical and beautiful. The control panel is a touch screen.

[0009] A further feature of this invention is that the control panel is vertically separated from the grille structure, and divides the grille structure into a first grid plate group with a first inclination angle and a second grid plate group with a second inclination angle, wherein the first inclination angle and the second inclination angle are opposite in direction.

[0010] A further feature of this invention is that the grid structure further includes a third set of grid plates connected to the first grid plate group and the second grid plate group. The end of the third set of grid plates near the first grid plate group is inclined away from the first grid plate group, and the end near the second grid plate group is inclined away from the second grid plate group. The inclination angles on both sides of the third set of grid plates gradually decrease towards the center.

[0011] By adopting the above technical solution, each set of grid plates can cooperate with each other to achieve multi-angle air intake and exhaust.

[0012] A further feature of this invention is that: the first grid plate group and the second grid plate group are each provided with a positioning rib near one end of the third grid plate group; the third grid plate group is provided with a positioning groove for accommodating the positioning rib; the positioning rib is provided with a limiting buckle protruding towards the third grid plate group; a limiting grid plate is fixedly connected to the inner wall of the third grid plate group; the limiting grid plate is provided with a limiting opening corresponding to the position of the limiting buckle; the limiting buckle is engaged with the limiting opening, so that the first grid plate group and the second grid plate group are respectively fixedly connected to the third grid plate group.

[0013] A further feature of this invention is that the purifier is cylindrical, the grille structure is annularly arranged around the outer periphery of the purifier, and together with the control panel, forms the side of the cylinder. The top plate and the base are both fixedly connected to the control panel, and respectively form the top and bottom surfaces of the cylinder.

[0014] A further feature of this invention is that the top plate and the grille structure are spaced apart to form an annular groove, and an exhaust hood is fixedly installed on the top of the grille structure. The exhaust hood forms the bottom wall of the annular groove, and the exhaust hood and the upper area of ​​the grille structure together form the air outlet of the air outlet area.

[0015] By adopting the above technical solution, the air intake and exhaust areas are increased, and the efficiency of air intake and exhaust is improved.

[0016] A further feature of this invention is that the exhaust screen is wavy.

[0017] By adopting the above technical solutions, not only is energy saving achieved, but noise reduction is also achieved.

[0018] A further feature of this invention is that the center of the exhaust screen is recessed downward to form an installation cavity, the top plate is placed into the installation cavity and fixedly connected to the exhaust screen, a portion of the top plate and a portion of the base extend toward the control panel and respectively form a first extension and a second extension, and the upper and lower ends of the control panel are fixedly connected to the first extension and the second extension, respectively.

[0019] By adopting the above technical solution, the grille structure can be arranged on the outside of the purifier body over a larger area, achieving large-area air intake and exhaust.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. An integrated grille structure is adopted, including at least two sets of grille plates with different orientations. The grille plates allow external airflow to be drawn into the main body of the purifier from multiple angles through the air inlet area, and the purified airflow is diffused outward from multiple angles through the air outlet area. Multi-angle air inlet and exhaust can be achieved using a single independent grille structure, which not only eliminates purification dead corners and improves purification efficiency, but also avoids setting up two sets of grille structures for air inlet and exhaust, saving production costs and optimizing equipment space utilization.

[0022] 2. The first, second, and third grid groups are interconnected. The tilt angles on both sides of each grid group gradually decrease towards the center, and the tilt angles of adjacent grid groups are opposite. This not only allows each grid group to cooperate to achieve multi-angle air intake and exhaust, but also creates airflow towards the center of each grid group during exhaust, thus improving air intake efficiency.

[0023] 3. The use of a wave-shaped exhaust grille disperses the exhaust air into a softer and more evenly distributed airflow, thereby reducing turbulence and wind resistance. This reduces the resistance that the exhaust components need to overcome, resulting in greater energy savings. In addition, when the airflow passes over a straight grille, it generates alternating vortices behind it, which are a significant source of noise. The irregular wave-shaped surface disrupts the formation of these regular vortices, thus reducing noise. Attached Figure Description

[0031] The present invention will be further described below with reference to the accompanying drawings.

[0032] A type of air purifier that supports multi-angle air intake and exhaust, such as Figure 1-6 As shown, the device includes a main body 1 of an air purifier, a purification component inside the main body 1, and a grille structure 2 covering the outer surface of the main body 1. The grille structure 2 has an air inlet area 211 and an air outlet area 212 arranged at intervals along the vertical direction. The grille structure 2 includes at least two sets of grille plates with different orientations. The grille plates allow external airflow to be drawn into the main body 1 of the air purifier through the air inlet area 211 at multiple angles, and the purified airflow diffuses outward through the air outlet area 212 at multiple angles. The purification assembly includes a filter element 11 and an exhaust assembly 12 located above the filter element 11. The filter element 11 and the exhaust assembly 12 are distributed vertically and together constitute the main body 1 of the purifier. The grille structure 2 is an integrated structure that covers the outer surface of the filter element 11 and the exhaust assembly 12. The air inlet area 211 of the grille structure 2 corresponds to the position of the filter element 11, and the air outlet area 212 of the grille structure 2 corresponds to the exhaust assembly 12. The grating groups located in the air inlet area 211 and the grating groups located in the air outlet area 212 are integrated structures and face the same direction as their respective grating groups. The grid arrays facing the same direction draw outside air from different areas into the filter element 11 through the air inlet zone 211, and then discharge the filtered air through the inside of the filter element 11 to the upward air outlet zone 212. Since the grid arrays in the air outlet zone 212 and the grid arrays in the air inlet zone 211 are an integrated structure, the filtered air can also be discharged to different areas. Using a set of independent grid structures 2 can achieve multi-angle air intake and exhaust, which not only eliminates purification dead corners and improves purification efficiency, but also avoids setting up two sets of grid structures 2 for air intake and exhaust, saving production costs and optimizing equipment space utilization.

[0033] Preferably, the purifier body 1 has a top plate 3 on top and a base 4 on the bottom. The grille structure 2 is located between the top plate 3 and the base 4. A control panel 5 is provided between the top plate 3 and the base 4. The control panel 5 is fixedly connected to the grille structure 2, so that the grille structure 2 is arranged in a ring between the top plate 3 and the base 4, forming a structural design in which the grille structure 2 is used in both the air intake and exhaust areas. This avoids setting up two sets of grille structures 2 for air intake and exhaust, saves production costs, and optimizes the space utilization of the equipment. The control panel 5 is a touch screen, which has a control circuit board that integrates a display module, a sound module, and an interaction module. The touch screen is a conventional existing technology and will not be described in detail here.

[0034] Preferably, the control panel 5 is vertically separated from the grille structure 2, dividing the grille structure 2 into a first grille group 21 with a first inclination angle and a second grille group 22 with a second inclination angle, the first inclination angle and the second inclination angle being opposite in direction. The sidewalls of the control panel 5 are screwed to the first grille group 21 and the second grille group 22 respectively. The ends of the first grille group 21 and the second grille group 22 near the control panel 5 are both inclined away from the control panel 5, thereby forming the first inclination angle and the second inclination angle in opposite directions. The ends of the first grille group 21 and the second grille group 22 near the third grille group 23 are both inclined away from the third grille group 23, and the inclination angles on both sides of the first grille group 21 and the second grille group 22 gradually decrease towards their respective centers.

[0035] Preferably, the grille structure 2 further includes a third set of grilles 23 connected to the first grille group 21 and the second grille group 22. The end of the third set of grilles 23 closest to the first grille group 21 is inclined away from the first grille group 21, and the end closest to the second grille group 22 is inclined away from the second grille group 22. The inclination angles on both sides of the third set of grilles 23 gradually decrease towards the center. The first grille group 21, the second grille group 22, and the third set of grilles 23 interlock to form a ring. The top and bottom of each set of grilles are fixedly connected to the purifier body 1 by bolts. Through the above structure, not only can each set of grilles cooperate to achieve multi-angle air intake and exhaust, but the inclination angles on both sides of each set of grilles gradually decrease towards the center, forming a gathering of air towards the center of the grilles during exhaust, thus improving the air intake efficiency.

[0036] Preferably, the first grid plate group 21 and the second grid plate group 22 are each provided with a positioning rib 20 near one end of the third grid plate group 23. The third grid plate group 23 is provided with a positioning groove 231 for accommodating the positioning rib 20. The positioning rib 20 is provided with a limiting buckle 201 protruding towards the third grid plate group 23. A limiting grid plate 24 is fixedly connected to the inner wall of the third grid plate group 23. The limiting grid plate 24 is provided with a limiting opening 241 corresponding to the position of the limiting buckle 201. The limiting buckle 201 is inserted into the limiting opening 241, so that the first grid plate group 21 and the second grid plate group 22 are respectively fixedly connected to the third grid plate group 23. The limiting buckle 201 is set at an angle to the positioning rib 20, and the limiting buckle 201 is tilted towards the limiting port 241. The limiting grid plate 24 is fixedly connected to the exhaust screen 7. When the positioning rib 20 is placed into the positioning groove 231, the first grid plate group 21 and the second grid plate group 22 are respectively connected to the third grid plate group 23. At this time, the limiting buckle 201 is fastened into the limiting port 241, which restricts the displacement of the first grid plate group 21, the second grid plate group 22 and the third grid plate group 23 in the horizontal and vertical directions, so that the first grid plate group 21, the second grid plate group 22 and the third grid plate group 23 are fastened to the purifier body 1.

[0037] Preferably, the purifier is cylindrical, the grille structure 2 is arranged in a ring around the outer periphery of the purifier, and together with the control panel 5, it forms the side of the cylinder. The top plate 3 and the base 4 are both fixedly connected to the control panel 5, and respectively form the top surface and bottom surface of the cylinder.

[0038] Preferably, the top plate 3 and the grille structure 2 are spaced apart to form an annular groove 6. An exhaust hood 7 is fixedly installed on the top of the grille structure 2. The exhaust hood 7 forms the bottom wall of the annular groove 6. The exhaust hood 7 and the upper area of ​​the grille structure 2 together form the air outlet of the air outlet area 212. The exhaust screen 7 is fixedly connected to the top plate 3. The spaced arrangement between the top plate 3 and the grille structure 2 allows the air purified by the filter element 11 to be discharged from both the side grille structure 2 and the top exhaust screen 7, increasing the exhaust area and improving exhaust efficiency. An air inlet screen 8 is installed between the base 4 and the grille structure 2. The air inlet screen 8 is arc-shaped and tilted towards the purifier body 1. The top of the arc is fixedly connected to the grille structure 2, and the bottom is fixedly connected to the base 4. The spaced arrangement between the base 4 and the grille structure 2 allows the purifier to draw air in from both the side grille structure 2 and the air inlet screen 8. Because the air inlet screen 8 is arc-shaped, the natural air entering from the end of the air inlet screen 8 is drawn into the top of the air inlet screen 8 in a streamlined manner, reducing the dispersion of natural air. It then converges with the natural air entering from the side grille structure 2 and passes through the filter element 11 together, thereby increasing the air intake area and improving air intake efficiency.

[0039] Preferably, the exhaust hood 7 is wavy. The wavy surface disperses the exhaust air into a softer, more evenly distributed airflow, thereby reducing turbulence and wind resistance. This reduces the resistance that the exhaust assembly 12 needs to overcome, achieving a more energy-efficient effect. In addition, when the airflow passes over a straight hood, it generates alternating vortices behind it, which are a significant source of noise. The irregular surface of the wavy shape disrupts the formation of these regular vortices, thus reducing noise. The wavy shape can be arranged horizontally or vertically. Taking a horizontally arranged wavy shape as an example, when the wind passes through the troughs of the wave, it is guided by the crests and discharged towards the outside along the contour of the crests, reducing the time the wind swirls in the annular groove 6 and improving exhaust efficiency.

[0040] Preferably, the exhaust screen 7 has a downwardly recessed center forming an installation cavity 71. The top plate 3 is inserted into the installation cavity 71 and fixedly connected to the exhaust screen 7. Part of the top plate 3 and part of the base 4 extend towards the control panel 5, forming a first extension 31 and a second extension 41, respectively. The upper and lower ends of the control panel 5 are fixedly connected to the first extension 31 and the second extension 41, respectively. The top plate 3 is fixed to the exhaust screen 7 with bolts, and the first extension 31 and the second extension 41 are fixed to the control panel 5 with bolts. The top plate 3, through the first extension 31, and the base 4, through the second extension 41, respectively fit against the outer contour of the control panel 5, forming a smooth curved surface in the vertical direction.

[0041] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
