TECHNICAL FIELD

[0001] The utility model relates to purifier technical field, specifically proposes a grating assembly and purifier. BACKGROUND

[0002] At present, when the grating is injection molded, the surrounding edge or the convex rib exists around the inner ring of the grating, the mold core needs to avoid the above structure when demolding, so that the structure of the mold core required for injection molding the grating is complex, the process difficulty of the grating when injection molding is large, and the process cost is high. SUMMARY

[0003] The utility model aims at least solve one of the technical problems existing in prior art or related art.

[0004] Therefore, the first aspect of the utility model provides a grating assembly.

[0005] The second aspect of the utility model provides a purifier.

[0006] Therefore, the first aspect of the utility model provides a grating assembly.

[0007] The grating assembly provided by the utility model comprises a grating and a first supporting part. The grating is provided with a through hole, and the through hole is used for air circulation to realize that the grating assembly can be used as an air inlet grating of a purifier. The grating also comprises a cavity with at least one open end, that is, the cavity can be open at one end and closed at the other end, or both ends are open.

[0008] The through hole is communicated with the cavity, the grating is a hollow structure with the through hole on the side wall, air can enter the cavity through the through hole, and the air can smoothly enter and exit.

[0009] The inner wall of the cavity extends to the edge of the grating near the open end, that is, from the inner wall of the cavity to the edge of the grating near the open end, no convex part is arranged on the open end or the inner wall of the cavity, the grating has no mold reverse structure at the open end, that is, the surrounding edge or the rib limiting structure exists, such a design avoids forming any convex rib or convex structure that may interfere with the mold core on the inner wall and the open end of the grating, and the grating meets the requirement that the mold core can be straight up and down.

[0010] The first support part is installed on the grid and arranged along the edge of the grid close to the opening end. The first support part can provide necessary support and fixation to ensure the stability and reliability of the grid during use. The design of the first support part can perfectly replace the surrounding edge, the first support part can prevent the deformation of the top of the grid, limit the grid, and build a support platform inside the grid for bearing the top body part.

[0011] In related designs, the grid has a surrounding edge or rib limiting structure at the opening. The mold core often needs to be designed to have multiple row structures to adapt to these complex shapes, to be expanded in the cavity and to be reduced at the opening to avoid the surrounding edge or rib limiting structure.

[0012] The grid has no protruding part arranged on the inner wall of the opening or the cavity, so that the mold core for injection molding the grid can be designed as a whole, the structure of the mold core is relatively simple, and the process cost of the grid injection molding is relatively low. When the grid is injection molded, only the mold core needs to be controlled straight up and straight down, the injection molding process of the grid is simplified, and the process difficulty of the grid injection molding is reduced.

[0013] In addition, the grid assembly in the above technical scheme provided by the utility model can also have the following additional technical features:

[0014] In some technical solutions of the utility model, optionally, the minimum width of the inner wall of the cavity at the opening is a first width; the minimum width of the inner wall of the cavity at a position other than the opening is a second width; the second width is greater than or equal to the first width.

[0015] In the technical solution, the width of the grid at the opening needs to consider the entry and exit of the mold core. If the first width is too small, the mold core may interfere with the inner wall of the cavity when entering and exiting, causing the mold to be damaged or the mold to need a complex design. The width of the inner wall of the cavity other than the opening should be large enough to accommodate the expansion of the mold core during filling and solidification, while avoiding unnecessary contact or interference with other parts of the mold.

[0016] The utility model sets the minimum width of the inner wall of the cavity at the opening to be a first width, the minimum width of the inner wall of the cavity at a position other than the opening to be a second width, and the second width to be greater than or equal to the first width, thereby ensuring that the mold core will not be hindered by the sudden narrowing of the inner wall of the cavity when entering and exiting the opening. At the same time, the above width range design also provides sufficient space for stable placement of the mold core in the cavity.

[0017] In some technical solutions of the utility model, optionally, the grid assembly further comprises a mounting column, the mounting column is arranged on the inner wall of the cavity and extends towards the opening; and the first support part is connected with the mounting column.

[0018] In the technical scheme, the mounting column provides a stable mounting base for the first supporting part, and further enhances the structural strength and stability of the grating assembly.

[0019] In some technical schemes of the utility model, optionally, the grating assembly further comprises a connecting piece, the connecting piece is arranged in the first supporting part and is connected with the mounting column.

[0020] In the technical scheme, the grating assembly further comprises a connecting piece, the connecting piece is arranged in the first supporting part and is connected with the mounting column, and stable connection between the two is realized. The connection of the connecting piece not only ensures the stability and reliability of the first supporting part in the grating assembly, but also avoids the security risks caused by loose or falling connection.

[0021] In some technical schemes of the utility model, optionally, the mounting column is provided with a first buckle at one end close to the first supporting part, and the first supporting part is provided with a first clamping groove.

[0022] In the technical scheme, in the design of the grating assembly, the first buckle is arranged at one end of the mounting column close to the first supporting part, and the corresponding first clamping groove is arranged on the first supporting part, so that a simple and effective connection mode is realized.

[0023] The mounting column is provided with a first buckle at one end close to the first supporting part. The first clamping groove corresponds to the first buckle, and the first clamping groove is arranged on the first supporting part. The connection mode through the clamping structure does not need complex tools or operation, and only needs to align the first supporting part with the mounting column and then press to realize quick connection. This connection mode improves the installation efficiency and reduces the labor cost.

[0024] The close fit of the first buckle and the first clamping groove ensures the connection stability between the first supporting part and the mounting column. Even under the condition of external force impact or vibration, the first buckle can be firmly kept in the first clamping groove, avoiding loose or falling connection, so that the supporting effect is realized.

[0025] In some technical schemes of the utility model, optionally, the first supporting part is provided with a second buckle, and the second buckle is clamped in the grating.

[0026] In the technical scheme, in the design of the grating assembly, the second buckle is additionally arranged for the first supporting part and is clamped in the grating. This design not only enhances the structural stability of the grating assembly, but also simplifies the installation process and improves the overall performance.

[0027] The second buckle firmly buckles the first supporting part on the grid body, enhancing the overall structural stability of the grid assembly. This connection method avoids safety hazards caused by loose or falling connections, improving the reliability and durability of the grid assembly.

[0028] Through the buckling of the second buckle and the grid, the installation process becomes more convenient and fast. Without complex tools or additional fixing parts, the first supporting part only needs to be aligned with the buckling part on the grid, and then pressed or slid to achieve installation, reducing installation cost and time.

[0029] In some technical solutions of the present application, optionally, the mounting column extends from one end of the grid away from the opening to one end of the grid close to the opening.

[0030] In this technical solution, the mounting column extends from one end of the grid away from the opening to one end of the grid close to the opening. In mold design, interference is a common and tricky problem. If the layout of the mounting column is unreasonable, it is easy to collide with the mold core during mold opening, resulting in mold damage or product quality decline.

[0031] The mounting column of the present application extends from one end of the grid away from the opening to one end of the grid close to the opening, ensuring that the extension direction of the mounting column is perpendicular to the movement direction of the mold core or at other non-interference angles. In this way, during mold opening, the mold core can smoothly enter and exit without any interference with the mounting column.

[0032] Extending the mounting column to one end of the grid close to the opening is equivalent to adding a support structure inside the grid, thereby improving the anti-deformation and load-bearing capacity of the grid. Under stress, the mounting column can disperse and bear part of the stress, preventing the grid from being damaged due to excessive local stress.

[0033] In some technical solutions of the present application, optionally, the number of mounting columns is multiple, and the multiple mounting columns are arranged along the circumference of the grid.

[0034] In this technical solution, the multiple mounting columns are evenly distributed along the circumference of the grid, which can more effectively disperse the external pressure or impact force borne by the grid. This way of dispersing stress can significantly reduce the load of a single mounting column, thereby improving the load-bearing capacity and anti-deformation capacity of the entire grid assembly.

[0035] The multiple mounting columns are arranged along the circumference, which is equivalent to forming a stable support network inside the grid, enhancing the overall rigidity and stability of the grid. The multiple mounting columns arranged along the circumference of the grid can more effectively plan the movement path of the mold core, avoiding interference with the mounting column during mold opening. This design helps to simplify the mold structure, improve the manufacturing precision and durability of the mold.

[0036] Optionally, the first supporting component is provided with a groove, and one end of the grid close to the opening is embedded in the groove.

[0037] In the technical scheme, in the design of the grid assembly, the groove is arranged on the first supporting component, and one end of the grid close to the opening is embedded in the groove, so that the structural stability is enhanced and the installation convenience is improved.

[0038] In some technical schemes of the utility model, optionally, the cross section of the grid is circular, oval, rectangular or polygonal.

[0039] In the technical scheme, on the one hand, the cross section of the grid is circular, and the grid with the circular cross section can generate smaller resistance when the fluid passes through, which is beneficial to the smooth flow of the fluid.

[0040] On the other hand, the cross section of the grid is oval, and the oval grid can more effectively utilize the space while keeping a relatively low fluid resistance compared with the circular grid.

[0041] On the other hand, the cross section of the grid is rectangular, and the rectangular grid is more stable in structure and can withstand a larger lateral pressure.

[0042] On the other hand, the cross section of the grid is polygonal, and the polygonal grid can be designed into different numbers of sides and shapes according to actual needs to adapt to different application scenarios.

[0043] In some technical schemes of the utility model, optionally, the grid assembly further comprises: a second supporting component, the second supporting component is arranged on the side of the grid away from the opening and protrudes from the inner wall of the cavity to the inside of the grid.

[0044] In the technical scheme, the second supporting component is arranged on the side of the grid away from the opening and protrudes from the inner wall of the cavity to the inside of the grid. The main function of the second supporting component is to realize plugging at the other end of the grid and support the filtering component. Through the structure protruding from the inner wall, the second supporting component can provide a stable supporting surface to ensure that the filtering component can be firmly installed in the grid assembly.

[0045] According to the second aspect of the utility model, the utility model provides a purifier comprising the grid assembly in any of the above technical schemes.

[0046] The purifier provided in the second aspect of the utility model comprises the grid assembly in any of the above technical schemes, so it has all the beneficial effects of the grid assembly in any of the above technical schemes, which will not be repeated here.

[0047] In some technical solutions of the utility model, optionally, the through hole is an air inlet, the purifier further comprises a first shell, a fan and a filtering component, the first shell is arranged on the grating assembly, and the first shell is provided with an air outlet; the fan is arranged in the first shell, one end of an air duct of the fan is communicated with the air inlet, and the other end of the air duct of the fan is communicated with the air outlet; the filtering component is arranged in the grating assembly and opposite to the air inlet.

[0048] In the technical solution, the through hole serves as the air inlet, the air inlet allows air to smoothly enter the interior of the purifier, and the structure of the grating assembly also plays a role in supporting and fixing other components.

[0049] The first shell is the main part of the purifier, and the first shell wraps the fan, the filtering component and other key components. The first shell is provided with an air outlet for discharging filtered air out of the purifier.

[0050] The fan is a power component in the purifier, and the fan is used for generating airflow to make air enter the purifier through the air inlet and be discharged from the air outlet after being filtered by the filtering component. The air duct design of the fan ensures smooth airflow and improves the purification efficiency.

[0051] The filtering component is the core part of the purifier, and the filtering component is arranged in the grating assembly and opposite to the air inlet. The filtering component can capture particulate matters, dust, pollen and other pollutants in the air to ensure that the discharged air is fresher and cleaner.

[0052] In some technical solutions of the utility model, optionally, the first support component is provided with a mounting groove recessed towards the interior of the grating assembly; and at least part of the first shell is arranged in the mounting groove.

[0053] In the technical solution, the first shell is partially embedded in the mounting groove of the first support component to realize the close cooperation between the two. This design not only enhances the stability of the purifier as a whole, but also helps to reduce vibration and noise. The mounting groove bears the first shell at the top, avoiding the first shell directly pressing on the filtering component to prevent the filtering component from deforming.

DETAILED DESCRIPTION

[0062] In order to more clearly understand the above purpose, features and advantages of the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0063] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below.

[0064] The following description refers to the accompanying drawings that show embodiments of the present application. Figures 1 to 4 The grid assembly 100 and the purifier 10 according to some embodiments of the present application are described below.

[0065] As Figure 1 and Figure 2As shown, in an embodiment of the present application, a kind of grid assembly 100 is provided, and the grid assembly 100 includes grid 110 and first support component 120, grid 110 is provided with through hole 112 and the cavity 116 of at least one end opening 114, through hole 112 is communicated with cavity 116, the inner wall 118 of cavity 116 extends to the edge of the end of grid 110 close to opening 114;First support component 120 is installed on grid 110, and is arranged along the edge of the end of grid 110 close to opening 114.

[0066] The grid assembly 100 provided by the present application includes grid 110 and first support component 120. The grid 110 is provided with a through hole 112 for air flow to enable the grid assembly 100 to be used as an air inlet grid of the purifier 10. The grid 110 further includes a cavity 116 with at least one end opening 114, i.e. the cavity 116 can have one end opening 114 and the other end closed, or both ends open 114.

[0067] The through hole 112 is communicated with the cavity 116, and the grid 110 is a hollow structure with a through hole 112 on the side wall. Air can enter the cavity 116 through the through hole 112, and air can smoothly enter and exit.

[0068] The inner wall 118 of the cavity 116 extends to the edge of the end of the grid 110 close to the opening 114, that is, from the inner wall 118 of the cavity 116 to the edge of the end of the grid 110 close to the opening 114, there is no protruding component on the opening 114 or the inner wall 118 of the cavity 116, and there is no mold undercut structure, i.e. the edge or rib limiting structure, at the opening 114 of the grid 110. Such design avoids forming any convex rib or protruding structure inside the grid 110 and at the opening 114 that may interfere with the mold core, and the grid 110 meets the requirement of the mold core extending upward and downward.

[0069] The first support component 120 is installed on the grid 110 and arranged along the edge of the end of the grid 110 close to the opening 114. The first support component can provide necessary support and fixation to ensure the stability and reliability of the grid 110 during use. The design of the first support component can perfectly replace the edge, and the first support component can prevent the deformation of the top of the grid 110, while building a support platform inside the grid 110 for carrying the top body part.

[0070] In related designs, the grid has an edge or rib limiting structure at the opening, and the mold core often needs to be designed with multiple row structures to adapt to these complex shapes, and to be expanded in the cavity and reduced at the opening to avoid the edge or rib limiting structure.

[0071] The utility model discloses a grid 110 does not have the protruding component setting on the inner wall 118 of opening 114 or cavity 116, so that the mold core for injection molding grid 110 can be designed as a whole, and the structure of the mold core is relatively simple, so that the process cost of grid 110 injection molding is lower.

[0072] Specifically, the first support component 120 is a partition plate, and the main function of the partition plate is to build a surrounding edge inside the grid 110 for carrying the top body part, so as to avoid the top body directly pressing on the filter screen inside the grid 110 and prevent the filter screen from deforming.

[0073] As shown in the drawings, Figure 3 In some embodiments of the utility model, the minimum width of the inner wall 118 of the cavity 116 at the opening 114 is a first width W1; the minimum width of the inner wall 118 of the cavity 116 at a position other than the opening 114 is a second width W2; and the second width W2 is greater than or equal to the first width W1.

[0074] In this embodiment, the width of the grid 110 at the opening 114 needs to be considered when the mold core is put in or taken out. If the first width W1 is too small, the mold core may interfere with the inner wall 118 of the cavity 116 when it is put in or taken out, which may cause damage to the mold or require a complex design of the mold. The width of the inner wall 118 of the cavity 116 other than the opening 114 should be large enough to accommodate the expansion of the mold core during the filling and curing process, while avoiding unnecessary contact or interference with other parts of the mold.

[0075] The utility model sets the minimum width of the inner wall 118 of the cavity 116 at the opening 114 to be a first width W1, and the minimum width of the inner wall 118 of the cavity 116 at a position other than the opening 114 to be a second width W2, and the second width W2 is greater than or equal to the first width W1, thereby ensuring that the mold core will not be hindered when it is put in or taken out of the opening 114 due to the sudden narrowing of the inner wall 118 of the cavity 116. At the same time, the above width range design also provides sufficient space for the stable placement of the mold core in the cavity 116.

[0076] By avoiding mold interference, the utility model can reduce wear and tear and damage during the process of putting in and taking out the mold, thereby prolonging the service life of the mold. It can ensure the stable placement and uniform filling of the mold core in the cavity 116, thereby improving the quality and consistency of the finished product.

[0077] As shown in the drawings, Figure 1 and Figure 2As shown, in some embodiments of the present application, the grid assembly 100 further comprises a mounting column 130, which is arranged on the inner wall 118 of the cavity 116 and extends towards the opening 114; the first support component 120 is connected with the mounting column 130.

[0078] In this embodiment, the mounting column 130 provides a stable mounting basis for the first support component 120, and further enhances the structural strength and stability of the grid assembly 100.

[0079] Specifically, the mounting column 130 is arranged on the inner wall 118 of the cavity 116 and extends towards the opening 114. This design ensures the close connection of the mounting column 130 with the grid 110, while avoiding interference with the mold core.

[0080] Specifically, the shape of the mounting column 130 can be cylindrical, square or other suitable shapes, depending on the connection method of the first support component 120 and the overall design of the grid 110.

[0081] The main function of the mounting column 130 is to serve as a connection point for the first support component 120. The mounting column 130 can be stably connected with the first support component 120. The mounting column 130 provides a solid mounting basis for the first support component 120, ensuring its stability and reliability in the grid assembly 100, so that it can cooperate with the first support component 120 to prevent the top of the grid 110 from deforming, and build a support platform inside the grid 110 to carry the top part of the fuselage.

[0082] Specifically, the mounting column 130 is a screw column, and the thickness of the screw column is generally large, which also enhances the overall strength of the grid assembly 100.

[0083] Specifically, according to the conventional grid design requirements, a circle of limiting grooves will be designed on the top of the inner circle of the grid for use with the grid, which will make the top of the inner circle of the grid have a circle of structure similar to the surrounding edge. Since it is a plastic part, it is produced by mold injection. In the mold design, in order to ensure that the surrounding ring on the top of the inner circle can be normally demolded, multiple row structures need to be designed inside the mold, and the mold will be more complex. The present application does not use a circle of clamping groove limiting structure, but directly extends multiple screw columns from the bottom of the grid 110 to the top of the grid 110, and directly uses the screw fixing method to complete the structure limiting with other assembled parts of the grid 110. This will ensure that the entire internal structure of the grid 110 is simple, the mold can be directly designed in a straight way, without the need to increase multiple internal sliders or row structures, and the mold manufacturing and injection molding process will be much simpler.

[0084] As Figure 1 and Figure 2As shown, in some embodiments of the present invention, optionally, the grille assembly 100 further includes a connector 140, which passes through the first support member 120 and is connected to the mounting post 130.

[0085] In this embodiment, the grille assembly 100 further includes a connector 140, which passes through the first support portion and is connected to the mounting post 130, thus achieving a stable connection between the two. The connection through the connector 140 not only ensures the stability and reliability of the first support component 120 in the grille assembly 100, but also avoids safety hazards caused by loosening or detachment of the connection.

[0086] Specifically, the presence of connector 140 enhances the overall structural strength of the grille assembly 100. Through the tight connection between connector 140 and the first support member 120 and mounting post 130, the grille assembly 100 exhibits better resistance to deformation when subjected to external pressure or impact.

[0087] Specifically, the connector 140 includes a connecting bolt, and the first support member 120 is provided with a first connecting hole. The connecting bolt passes through the first connecting hole and connects with the mounting post 130.

[0088] Specifically, the mounting post 130 is provided with a second connecting hole, and the connecting bolt passes through the first connecting hole and then enters the second connecting hole.

[0089] like Figure 1 and Figure 2 As shown, in some embodiments of this utility model, optionally, a first buckle 150 is provided at one end of the mounting post 130 near the first support member 120, and a first slot 160 is provided in the first support member 120, with the first buckle 150 engaging in the first slot 160.

[0090] In this embodiment, in the design of the grille assembly 100, a simple and effective connection method is achieved by setting a first buckle 150 at one end of the mounting post 130 near the first support member 120 and setting a corresponding first slot 160 on the first support member 120.

[0091] A first latch 150 is provided at one end of the mounting post 130 near the first support member 120. Specifically, the first latch 150 may be a protrusion made of elastic material or a hook formed by bending a metal sheet.

[0092] The first clamping groove 160 corresponds to the first clamping buckle 150, and the first clamping groove 160 is arranged on the first supporting component 120. The connection through the clamping structure does not require complex tools or operations, and only needs to align the first supporting component 120 with the mounting column 130 and then press to achieve quick connection. This connection mode improves the installation efficiency and reduces the labor cost.

[0093] The close fit of the first clamping buckle 150 and the first clamping groove 160 ensures the connection stability between the first supporting component 120 and the mounting column 130. Even if subjected to external force impact or vibration, the first clamping buckle 150 can be firmly retained in the first clamping groove 160, avoiding loose connection or falling off, thereby realizing the supporting effect.

[0094] As shown in Figure 1 and Figure 2 In some embodiments of the utility model, the first supporting component 120 is provided with a second clamping buckle 170, and the second clamping buckle 170 is clamped on the grid 110.

[0095] In this embodiment, the second clamping buckle 170 is additionally arranged on the first supporting component 120 in the design of the grid assembly 100, and is clamped on the grid 110. This design not only enhances the structural stability of the grid assembly 100, but also simplifies the installation process and improves the overall performance.

[0096] Specifically, the second clamping buckle 170 is arranged on the first supporting component 120, and the second clamping buckle 170 can be a protruding structure made of elastic material or a clamping hook formed by special processing of a metal sheet.

[0097] Specifically, the clamping mode of the second clamping buckle 170 and the grid 110 can be direct clamping or sliding clamping. The direct clamping buckle usually has elasticity and can be easily clamped into the reserved clamping groove or hole on the grid 110. The sliding clamping buckle needs to be aligned with the clamping part on the grid 110 first, and then slid in a specific direction to realize clamping.

[0098] The second clamping buckle 170 firmly clamps the first supporting component 120 on the main body of the grid 110, enhancing the overall structural stability of the grid assembly 100. This connection mode avoids the safety hazards caused by loose connection or falling off, improving the reliability and durability of the grid assembly 100.

[0099] Through the clamping of the second clamping buckle 170 and the grid 110, the installation process becomes more convenient and fast. Without complex tools or additional fixing parts, only needs to align the first supporting component 120 with the clamping part on the grid 110, and then press or slide to realize installation, reducing the installation cost and time.

[0100] AsFigure 1 and Figure 2 As shown in

[0101] In this embodiment, the mounting post 130 extends from the end of the grid 110 away from the opening 114 to the end of the grid 110 close to the opening 114. In mold design, interference is a common and tricky problem. If the layout of the mounting post 130 is unreasonable, it is easy to collide with the mold core during mold opening, resulting in mold damage or product quality decline.

[0102] The mounting post 130 of the utility model extends from the end of the grid 110 away from the opening 114 to the end of the grid 110 close to the opening 114, which ensures that the extension direction of the mounting post 130 is perpendicular to the movement direction of the mold core or at other non-interference angles. In this way, during mold opening, the mold core can smoothly enter and exit without any interference with the mounting post 130.

[0103] Extending the mounting post 130 to the end of the grid 110 close to the opening 114 also means adding a support structure inside the grid 110, thereby improving the anti-deformation and load-bearing capacity of the grid 110. Under stress conditions, the mounting post 130 can disperse and bear part of the stress, preventing the grid 110 from being damaged due to excessive local stress.

[0104] As shown in Figure 1 and Figure 2 In some embodiments of the utility model, the number of mounting posts 130 is multiple, and the multiple mounting posts 130 are arranged along the circumference of the grid 110.

[0105] In this embodiment, the multiple mounting posts 130 are evenly distributed along the circumference (such as the direction indicated by arrow A in Figure 1 ) of the grid 110, which can more effectively disperse the external pressure or impact force borne by the grid 110. This way of dispersing stress can significantly reduce the load of a single mounting post 130, thereby improving the load-bearing capacity and anti-deformation capacity of the entire grid assembly 100.

[0106] The multiple mounting posts 130 are arranged along the circumference, which forms a stable support network inside the grid 110, enhancing the overall rigidity and stability of the grid 110. Arranging multiple mounting posts 130 along the circumference of the grid 110 can more effectively plan the movement path of the mold core, avoiding interference with the mounting post 130 during mold opening.

[0107] As shown in Figure 2 and Figure 2 ​​​As shown in some embodiments of the present application, the first support component 120 is provided with a groove 122, and one end of the grid 110 close to the opening 114 is embedded in the groove 122.

[0108] In this embodiment, in the design of the grid assembly 100, the groove 122 is provided on the first support component 120, and one end of the grid 110 close to the opening 114 is embedded in the groove 122, which not only enhances the structural stability but also improves the installation convenience.

[0109] In some embodiments of the present application, the cross section of the grid 110 is circular, elliptical, rectangular or polygonal.

[0110] In this embodiment, on the one hand, the cross section of the grid 110 is circular, and the circular cross section of the grid 110 can generate smaller resistance when the fluid passes through, which is conducive to the smooth flow of the fluid.

[0111] On the other hand, the cross section of the grid 110 is elliptical, and the elliptical grid 110 can utilize space more effectively while maintaining a low fluid resistance compared to the circular grid 110.

[0112] On the other hand, the cross section of the grid 110 is rectangular, and the rectangular grid 110 is more stable in structure and can withstand larger lateral pressure.

[0113] On the other hand, the cross section of the grid 110 is polygonal, and the polygonal grid 110 can be designed with different number of sides and shapes according to actual needs to adapt to different application scenarios.

[0114] As shown in some embodiments of the present application, the grid assembly 100 further comprises a second support component 180, which is provided on the side of the grid 110 away from the opening 114 and protrudes from the inner wall 118 of the cavity 116 towards the inside of the grid 110. Figure 1 Figure 2 As shown in some embodiments of the present application, the grid assembly 100 further comprises a second support component 180, which is provided on the side of the grid 110 away from the opening 114 and protrudes from the inner wall 118 of the cavity 116 towards the inside of the grid 110.

[0115] In this embodiment, the second support component 180 is provided on the side of the grid 110 away from the opening 114 and protrudes from the inner wall of the cavity 116 towards the inside of the grid 110. The main function of the second support component 180 is to block the other end of the grid 110 and support the filter component 400. Through the structure of protruding from the inner wall, the second support component 180 can provide a stable support surface to ensure that the filter component 400 can be firmly installed in the grid assembly 100.

[0116] Specifically, the second support component 180 forms the bottom wall of the grid 110.

[0117] As shown in some embodiments of the present application, the grid assembly 100 further comprises a filter component 400, which is provided in the cavity 116 of the grid 110. Figure 1 ​As shown, in one embodiment of the present invention, a purifier 10 is provided, which includes a grille assembly 100 as described in any of the above embodiments.

[0121] The first housing 200 is the main body of the purifier 10, and it encloses key components such as the fan 300 and the filter element 400. An air outlet 210 is provided on the first housing 200 for discharging filtered air from the purifier 10.

[0122] The fan 300 is the power component in the purifier 10. The fan 300 generates airflow, allowing air to enter the purifier 10 through the air inlet 190, and after being filtered by the filter element 400, it is discharged from the air outlet 210. The air duct 330 design of the fan 300 ensures smooth airflow and improves purification efficiency.

[0123] The filter element 400 is the core component of the air purifier 10. It is located within the grille assembly 100 and faces the air inlet 190. The filter element 400 can capture pollutants such as particulate matter, dust, and pollen in the air, ensuring that the exhaust air is fresher and cleaner.

[0124] When the fan 300 is started, the fan 300 will generate suction, causing air to enter the interior of the purifier 10 through the air inlet 190 of the grille assembly 100. The air entering the purifier 10 will be filtered by the filter component 400, which can capture pollutants such as particulate matter, dust, and the like in the air. The filtered air will enter the air duct 330 of the fan 300 and ultimately be discharged from the air outlet 210 of the first shell 200. The purifier 10 can continuously provide fresh, clean air for the indoor environment.

[0125] As shown in Figure 4 and Figure 4 In some embodiments of the present application, the first support component 120 is optionally provided with a mounting groove 124 recessed towards the interior of the grille assembly 100; at least part of the first shell 200 is arranged in the mounting groove 124.

[0126] In this embodiment, by partially embedding the first shell 200 in the mounting groove 124 of the first support component 120, a close fit between the two is achieved. This design not only enhances the stability of the purifier 10 as a whole, but also helps to reduce vibration and noise. The mounting groove 124 carries the first shell 200 at the top, avoiding direct pressure of the first shell 200 on the filter component 400, preventing deformation of the filter component 400.

[0128] In this embodiment, the purifier includes a main control board 920, which is the control core of the entire product. The chip included therein contains control schemes for all electrical components and display schemes of the entire machine.

[0129] The purifier 10 includes a top cover 500, which is the top appearance surface of the product and can hold objects, having certain load-bearing requirements.

[0130] The purifier 10 includes an upper shell 600, which supports the top cover 500 at the top and is connected to the air outlet grille 800 at the bottom, playing a role of connecting the upper and lower parts, and the appearance surface is a gradually flat arc surface, which, together with the appearance arc surface of the air outlet grille 800, forms a flow guide layer of the air outlet 210 of the air duct 330 system.

[0131] The purifier 10 further comprises a power supply box 700 made of fireproof material and mounted on the motor support 900, inside which a power board 710 is sleeved to ensure complete isolation of the power board 710 and the safety of the whole machine.

[0132] The power board 710 is connected with external power supply through a power line and converts the voltage into the voltage required by the whole machine through the power board 710 to provide power to the whole machine.

[0133] The purifier 10 further comprises an air outlet grille 800 which is the air outlet 210 of the purifier 10. The appearance surface of the air outlet 210 is an arc surface, and the inclined arc transition scheme with the inner height being higher than the outer height is conducive to the flow guide of the airflow.

[0134] The purifier 10 further comprises a motor support 900 which is a load-bearing component and inside which a motor 310 is mounted. The outer ring of the guide vane is designed in an inclined manner, and the height of the outer ring of the guide vane is lower than that of the inner ring.

[0135] The purifier 10 further comprises a motor 310 which is a power component of the machine and the power core of the whole machine and is assembled in the middle region of the motor support 900.

[0136] The purifier 10 further comprises a fan wheel 320 which is a component driven by the motor 310 to stir air to form an airflow.

[0137] The purifier 10 further comprises an air duct 330 which is a medicine injection component in the air duct 330 system of the purifier 10. The bottom is an air inlet 190, and the airflow passing through the filtering component 400 directly passes through the air inlet 190 at the bottom of the air duct 330 to enter the inside of the air duct 330 system. The top of the air duct 330 is connected with the motor support 900 and is fixed by screws. The motor 310, the fan wheel 320 and the air duct 330 constitute a fan 300.

[0138] The purifier 10 further comprises a grille assembly 100 which forms an air inlet grille and is an air inlet component of the purifier 10.

[0139] The filtering component 400 of the purifier 10 is a filter screen which is a core component of the whole purification and adsorption of the purifier 10 and is assembled inside the air inlet grille.

[0140] The purifier 10 further comprises a base 910 which is a base of the product and supports all the loads of the product.

[0141] The first supporting part 120 in the grille assembly 100 is a partition plate, which is a secondary appearance surface of a product, and the main function of the partition plate is to be fixed with a screw of an air inlet grille to prevent the top of the air inlet grille from being easily deformed, and to build a support platform inside the air inlet grille to bear the top body part, thereby avoiding the top body directly pressing on the filter screen to prevent the filter screen from being deformed.

[0142] The air inlet grille mainly comprises a grille assembly 100 and a filter screen;

[0143] The bottom of the grille assembly 100 is closed, and the filter screen is borne inside, and a grille 110 hole is formed around the grille assembly 100 for air inlet;

[0144] The main function of the partition plate is to be fixed with a screw of an air inlet grille to prevent the top of the air inlet grille from being easily deformed, and to build a support platform inside the air inlet grille to bear the top body part, thereby avoiding the top body directly pressing on the filter screen to prevent the filter screen from being deformed.

[0145] According to the conventional air inlet grille structure design, a limiting groove is designed on the top of the inner ring of the air inlet grille, which is used for slot limiting with the grille, so that the top of the inner ring of the air inlet grille has a structure similar to a surrounding edge, and since it is a plastic part, a mold injection production mode is adopted, and when the mold is designed, in order to ensure that the surrounding ring on the top of the inner ring can normally be demolded, a plurality of row position structures need to be designed inside the mold, and the mold is very complex.

[0146] In the utility model, a limiting groove limiting structure is not adopted, a plurality of screw columns are directly designed from the bottom of the air inlet grille to the top of the air inlet grille, and a screw fixing mode is directly adopted to complete structure limiting with other assembly parts of the air inlet grille.

[0147] At the same time, the plurality of screw column structures are directly designed from the bottom, and since the thickness of the screw column is generally large, the overall strength of the product is also strengthened;

[0148] It should be noted that the bottom of the air inlet grille is closed, if the bottom is not completely closed, as long as the inner ring of the bottom is designed to have a structure, it needs to be noted that the inner ring on the other side cannot be designed to have a structure, so as to ensure the simplicity of the mold.

[0149] Meanwhile, if the top is closed or a ring of surrounding ribs is opened in the inner ring of the top, that is, the partition support platform structure in the present scheme is directly realized through the air inlet grille, only the bottom is completely punched through, and a plurality of screw columns can be directly fixed with the base screws of the bottom, and the same effect as the present scheme can be achieved.

[0150] In summary, the present application avoids forming any convex ribs or convex structures that may interfere with the mold core inside the grid 110 and at the opening 114 through the design of the grid 110 and the first support member 120, while achieving necessary support, simplifying the mold core, improving filling efficiency, and reducing the manufacturing process difficulty and cost of the grid 110. The present application simplifies the internal structure of the grid 110, simplifies complex problems, and makes the injection molding process of the grid 110 more simple and efficient.
