The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0035] In the description of the present invention, it should be understood that the descriptions involving orientation, such as the orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0036] In the description of the utility model, if there is a description of first and second, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0037] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0038] Reference Figure 1 As shown, the grille mounting structure 1000 of the embodiment of the utility model comprises a housing 100 and a filter 200, wherein the housing 100 is provided with an air inlet 110, and the air inlet 110 is opened on the outer wall of the housing 100. The filter 200 comprises a grille 201 and a filter screen, the filter 200 is mounted at the air inlet 110 of the housing 100, and is detachably connected to the housing 100, and the filter 200 covers the air inlet 110, and the filter screen can filter the air entering the housing 100 through the air inlet 110. The grille mounting structure 1000 of the embodiment is suitable for a mobile air conditioner, the housing 100 is the rear shell of the mobile air conditioner, and the air inlet 110 is specifically arranged on the rear shell of the mobile air conditioner. In some embodiments, the housing 100 can also be the overall outer shell of the mobile air conditioner.

[0039] Reference Figure 2 and Figure 3 As shown, in the embodiment, the air inlet 110 is formed on adjacent two side walls of the shell 100, and the two side walls are arranged at an angle to each other. Specifically, the air inlet 110 extends to different side walls of the shell 100, a part of the air inlet 110 is located on the rear side wall of the shell 100, and the other part is located on the right side wall of the shell 100. The cross-sectional shape of the air inlet 110 is roughly L-shaped, and the opening area is larger, so that the size of the air inlet 110 can be increased, which is beneficial to increase the air intake.

[0040] In the related art, the grille 201 and the filter are separate parts. When assembling, the filter and the grille 201 need to be installed at the air inlet 110 in sequence, and the filter is clamped and fixed by the grille 201. The structure is complicated. When the user cleans the filter, the grille 201 and the filter need to be disassembled at the same time, which is cumbersome. In the embodiment of the utility model, the grille 201 and the filter adopt an integral molding structure, and the grille 201 and the filter are specifically formed into a whole by integral injection molding using an injection molding process. In this way, the filter element 200 has the functions of the grille 201 and filtering at the same time, and the filter element 200 is bent as a whole so that the filter element 200 can cover the air inlet 110.

[0041] It is understandable that the cross-sectional shape of the filter element 200 in the embodiment is roughly L-shaped, and the filter element 200 matches the air inlet 110, so that a part of the filter element 200 is located at the rear side of the housing 100, and the other part is located at the right side of the housing 100, ensuring that the filter element 200 can completely cover the air inlet 110. Compared with the air inlet 110 and the filter element 200 of the planar structure, by setting the air inlet 110 and the filter element 200 in an L-shape, the air intake volume is larger and the layout design of the air inlet 110 is more flexible. Of course, the air inlet 110 is not limited to being set at the rear and right sides of the shell 100. The air inlet 110 can be set at the rear and left sides of the shell 100, or the air inlet 110 can extend to the rear, left and right sides of the shell 100. In this case, the cross-sectional shape of the air inlet 110 is roughly U-shaped, and the air inlet 110 has a larger coverage area and a larger air intake volume. According to the shape of the air inlet 110, the corresponding filter element 200 is selected for matching installation, and the specific shapes of the air inlet 110 and the filter element 200 are set according to actual application requirements.

[0042] Reference Figure 2As shown, it can be understood that the grille 201 is integrated with the filter screen, wherein the plastic frame of the filter element 200 is the grille 201, and the filter screen is a metal wire mesh. A plurality of through holes 202 are distributed on the plastic frame, and the through holes 202 are in the shape of long strips. After the grille 201 and the filter screen are injection molded, the filter screen can cover all the through holes 202. The structure of the filter screen is not shown in the accompanying drawings. The bending angle of the grille 201 is set according to the angle between the rear side wall and the right side wall of the housing 100. After the filter element 200 is formed, a bending section 203 is formed at the transition connection between the rear side wall and the right side wall. The bending section 203 has a certain curvature to enhance the modeling effect. The shape of the through hole 202 is not limited to a long strip, and can also be a circular, elliptical, polygonal, and other shapes.

[0043] It is understandable that when air passes through the filter element 200 along the through hole 202, dust, debris, etc. in the air can be filtered out through the filter. During assembly, the filter element 200 is directly installed at the air inlet 110 of the housing 100. Specifically, it can be detachably connected with the housing 100 by means of a buckle 230, a screw, a magnetic attraction, etc. The filter element 200 is a single component. It only needs to be assembled on the housing 100 to complete the installation of the grille 201 and the filter, which effectively improves the assembly efficiency. The number of parts is small, making it easier to disassemble the filter element 200, and convenient for users to clean and maintain the filter element 200.

[0044] Reference Figure 2 and Figure 3 As shown, along the length direction of the filter element 200, one end of the filter element 200 is provided with a plug-in portion 210, and the other end is provided with a buckle portion 220, and the shell 100 is provided with a slot 120 and a card slot 130, wherein the slot 120 cooperates with the plug-in portion 210 for plugging, and the card slot 130 cooperates with the buckle portion 220 for buckling, so that the filter element 200 and the shell 100 can be quickly disassembled and assembled.

[0045] Specifically, the slot 120 is arranged on the right side wall of the housing 100 and is located at the edge of the air inlet 110, and the card slot 130 is arranged on the rear side wall of the housing 100 and is close to the air inlet 110. When assembling, the filter element 200 is inserted into the slot 120 through the plug-in portion 210, and the buckle portion 220 is buckled into the card slot 130. Among them, the plug-in portion 210 can be a plug-in structure matching the slot 120, for example, a plug-in structure such as a latch 211 or a buckle, and the above plug-in structure can be inserted into the slot 120 for positioning. The buckle portion 220 can be a buckle structure matching the card slot 130, for example, a buckle 230, a lock, etc. The buckle portion 220 and the card slot 130 are connected by buckling or clamping, so that the filter element 200 can be connected to the housing 100, and the disassembly and assembly operation is more convenient and quick compared with the fixing method such as screws.

[0046] Reference Figure 2and Figure 3 As shown, in some embodiments, the plug-in portion 210 is specifically a plug pin 211, and the buckle portion 220 is an elastic buckle 221. Four plug pins 211 are provided on one side of the filter element 200, and the four plug pins 211 are spaced and distributed at the edge of the filter element 200 along the height direction of the filter element 200. Two elastic buckles 221 are provided on the other side of the filter element 200, and the two elastic buckles 221 are spaced and distributed at the edge of the filter element 200 along the height direction of the filter element 200. It can be understood that four slots 120 and two card slots 130 are provided on the housing 100, and the four slots 120 are spaced and distributed on the right side wall of the housing 100, and the two card slots 130 are spaced and distributed on the rear side wall of the housing 100, to ensure the stability and reliability of the connection structure between the filter element 200 and the housing 100.

[0047] Reference Figure 3 As shown, during assembly, the right end of the filter element 200 is first inserted into the slot 120 through the latch 211, and the latch 211 cooperates with the slot 120 to play a positioning role. At this time, the filter element 200 can be rotated around the plug-in position under the action of external force, so that the left end of the filter element 200 is close to the direction of the card slot 130, wherein the above-mentioned plug-in position can be understood as the position where the latch 211 is connected to the slot 120. When the filter element 200 rotates to a position that completely covers the air inlet 110, it is buckled in the card slot 130 through the elastic buckle 221, so that the filter element 200 can be quickly assembled. Figure 3 The direction indicated by the arrow below the middle filter element 200 is the direction in which the filter element 200 rotates around the insertion point.

[0048] Reference Figure 5 As shown, it should be noted that when the filter element 200 is rotated to a position close to the slot 130, the elastic buckle 221 is squeezed to deform and inserted into the slot 130, so that the elastic buckle 221 is clamped in the slot 130 by deformation to achieve the purpose of fixing. When disassembly is required, the elastic buckle 221 is manually pressed to deform and remove the elastic buckle 221 from the slot 130, and then the latch 211 is separated from the slot 120, thereby realizing the disassembly and separation of the filter element 200 and the housing 100, which is easy to operate.

[0049] Of course, the latch 211 and the elastic buckle 221 are not limited to the number shown in the above embodiment. The latch 211 and the elastic buckle 221 can be set to have the same number. For example, the number of the latch 211 and the elastic buckle 221 can be two, three or more respectively. Considering that the connection structure between the filter element 200 and the housing 100 is sufficiently stable, in some embodiments, the number of the latch 211 and the elastic buckle 221 is respectively set to at least two, which is selected according to the actual shape and size requirements of the filter element 200. It can be understood that the specific number of the slot 120 and the card slot 130 is set according to the number of the latch 211 and the elastic buckle 221. In addition, the latch 211 and the elastic buckle 221 can also be set at both ends of the filter element 200 along the height direction, and the positions of the slot 120 and the card slot 130 are adjusted accordingly. For example, the pin 211 is set at the lower end of the filter element 200, and the elastic buckle 221 is set at the upper end of the filter element 200. First, the pin 211 at the lower end of the filter element 200 is inserted into the slot 120 on the lower side of the air inlet 110, and then the filter element 200 is rotated upward so that the elastic buckle 221 at the upper end of the filter element 200 can be buckled into the slot 130 on the upper side of the air inlet 110.

[0050] Reference Figure 1 and Figure 5 As shown, in some embodiments, the shell 100 is provided with a recess 170, and the recess 170 is connected to the card slot 130 on the side close to the filter element 200. The recess 170 is specifically formed by the rear side wall of the shell 100 being recessed toward the interior of the shell 100. When removing the filter element 200, a finger can be inserted into the recess 170, which makes it convenient for the finger to press the elastic buckle 221 to disengage the elastic buckle 221 from the card slot 130, and the operation is faster.

[0051] Reference Figure 3 and Figure 7 As shown, the housing 100 is provided with a limiting edge 140 along the periphery of the air inlet 110, and the slot 120 is a notch 121 formed on the limiting edge 140. The number of the notches 121 is consistent with the number of the latches 211 on the filter element 200. The latches 211 can pass through the notches 121 from the outside of the housing 100 and be inserted into the inside of the housing 100, so as to position the right end of the filter element 200. Since one side of the notch 121 is an open structure, it is convenient for the filter element 200 to rotate around the plug-in position. It can be understood that the periphery of the filter element 200 is limited by the limiting edge 140 to prevent the filter element 200 from passing through the air inlet 110 and entering the interior of the housing 100.

[0052] Reference Figure 4 and Figure 6As shown, the inner wall of the shell 100 is provided with a first protrusion 180, and the first protrusion 180 is arranged adjacent to the notch 121; the latch 211 is flat, and a second protrusion 2111 is arranged on the side of the latch 211 facing the notch 121. When the latch 211 is inserted into the notch 121, the first protrusion 180 and the second protrusion 2111 abut against each other, thereby being able to cooperate to play a limiting role, so that the filter element 200 can rotate around the plug-in position more stably.

[0053] In some embodiments, reference Figure 6 and Fig. 9 As shown, a first guiding bevel 181 is provided on the side of the first protrusion 180 facing away from the notch 121, and a second guiding bevel 2112 is provided on the side of the second protrusion 2111 facing the notch 121, wherein the first guiding bevel 181 and the second guiding bevel 2112 are inclined in the same direction, so that the first guiding bevel 181 and the second guiding bevel 2112 can abut against each other, the limiting structure is more stable, and the pin 211 is not easy to disengage from the notch 121 during the rotation of the filter element 200.

[0054] Specifically, combined Fig. 9 It can be understood that the first protrusion in the embodiment is specifically a rib protruding from the inner wall of the housing 100, and the rib is transitionally connected to the bottom wall of the notch 121; the second protrusion is specifically a protrusion protruding from the surface of the plug 211, and after the plug 211 is inserted into the notch 121, the protrusion and the rib can abut against each other, wherein the rib is formed with a first guide slope 181 on the side facing the protrusion, and a second guide slope 2112 is formed on the side facing the rib. It should be noted that Fig. 9 The ribs and protrusions shown are only examples, and their specific shapes and sizes can be adjusted according to actual requirements and are not specifically limited.

[0055] Reference Figure 2 and Figure 3 As shown, four buckles 230 are respectively provided on the upper and lower sides of the filter element 200, and the buckle 230 position 150 is on the side wall of the filter element 200 facing the air outlet; the upper and lower limiting edges 140 are respectively provided with four buckle positions 150, that is, the eight buckles 230 are buckled with the eight buckle positions 150 in a one-to-one correspondence, so that the upper and lower ends of the filter element 200 can be fixed, and in this way, the connection structure at the left and right ends of the filter element 200 is matched, so that the four sides of the filter element 200 can be fitted on the limiting edges 140, ensuring that the filter element 200 and the shell 100 are more closely matched, the surface transition between the two is also smoother, the installation gap is smaller and more uniform, and the overall appearance is more beautiful.

[0056] Combination Figure 1 and Figure 4It can be understood that since the filter element 200 is L-shaped, the two ends of the filter element 200 need to be fixed on different sides of the shell 100, and four buckle positions 150 are provided on the right side wall of the shell 100, and the four buckle positions 150 on the right side are distributed on the upper and lower sides of the air inlet 110; four buckle positions 150 are provided on the rear side wall of the shell 100, and the four buckle positions 150 on the rear side are distributed on the upper and lower sides of the air inlet 110. During assembly, the buckle 230 is directly buckled to the buckle position 150, which is easy to operate, and can realize rapid assembly of the filter element 200, and the structure is stable and reliable.

[0057] It should be noted that the number of buckles 230 and buckle positions 150 is not limited to that shown in the above embodiments, and is selected based on the actual shape and size requirements of the filter element 200 and the air outlet. It can be understood that the longer the length of the filter element 200 and the air outlet, the more buckles 230 and buckle positions 150 are set along the length direction of the filter element 200 to ensure that the filter element 200 is installed more stably.

[0058] For details, refer to Figure 4 and Figure 7 As shown, after the latch 211 is positioned with the notch 121, when the filter element 200 rotates around the insertion point to the right position, the buckles 230 are buckled in the buckle positions 150 one by one, and the elastic buckles 221 are buckled in the card slot 130, thereby completing the installation of the filter element 200. In addition, the latch 211, the elastic buckle 221, the buckle 230 and the filter element 200 are an integrally formed structure, and the slot 120, the card slot 130, the limiting edge 140, the buckle position 150 and the housing 100 are an integrally formed structure, and only a single filter element 200 can meet the installation requirements, without relying on screws and other components for connection, reducing the number of parts and components, and effectively improving assembly efficiency.

[0059] Reference Figure 3 and Figure 8 As shown, in some embodiments, each buckle position 150 is provided with an elastic rib 151, and the elastic rib 151 is connected to the limiting edge 140. Compared with the structure in which the buckle 230 is directly buckled with the limiting edge 140, since the elastic rib 151 has a certain elastic deformation, when the buckle 230 abuts against the elastic rib 151, the elastic rib 151 undergoes elastic deformation, which makes it easier for the buckle 230 to be buckled on the elastic rib 151.

[0060] It can be understood that in the embodiment, ribs 152 are respectively provided at both ends of the elastic rib 151, and the size of the rib 152 is smaller than that of the elastic rib 151, and the rib 152 is a curved structure, so that the rib 152 can be easily deformed, thereby providing elastic force to the elastic rib 151; in addition, the side of the elastic rib 151 away from the air inlet 110 is spaced from the limiting edge 140, and a through groove 153 is formed, that is, a hollow structure is formed on one side of the elastic rib 151 through the through groove 153. When the buckle 230 abuts against the elastic rib 151, the elastic rib 151 is subjected to an extrusion force in the direction of the through groove 153, so that the elastic rib 151 is deformed, so that the buckle 230 and the elastic rib 151 can be quickly buckled, and the elastic rib 151 is in a compressed state during the buckling, and the elastic rib 151 will generate elastic force to press the buckle 230, thereby improving the stability of the buckling.

[0061] Reference Figure 8 As shown, in the embodiment, a third guide slope 1511 is provided on the side of the elastic rib 151 away from the through groove 153. When the elastic rib 151 contacts the buckle 230, the third guide slope 1511 can guide the buckle 230 to be quickly buckled onto the elastic rib 151, making the buckling operation more labor-saving and faster.

[0062] Reference Figure 3 As shown, in some embodiments, the shell 100 is further provided with a plurality of baffles 160 at the air inlet 110. The plurality of baffles 160 are cross-distributed in the transverse and longitudinal directions, and the baffles 160 are connected to the limiting edges 140 to form a grid structure. The grid structure can support the filter element 200, improve the installation strength of the filter element 200, and prevent the filter element 200 from being sunken and deformed toward the inside of the shell 100.

[0063] An embodiment of the utility model also provides a mobile air conditioner, including the grille mounting structure 1000 of the above embodiment, the shell 100 is the rear shell of the mobile air conditioner, the air inlet 110 is arranged on the rear shell of the mobile air conditioner, the filter element 200 is detachably connected to the rear shell, the filter element 200 is installed at the air inlet 110, and the air passing through the air inlet 110 can be filtered through the filter element 200.

[0064] Reference Figure 1 and Figure 3 As shown, specifically, the air inlet 110 is formed on the rear side wall and the right side wall of the housing 100, which is conducive to increasing the air intake of the mobile air conditioner and achieving better use effect. The specific position of the air inlet 110 can be set according to the actual application requirements of the mobile air conditioner, and the corresponding filter element 200 can be selected according to the shape of the air inlet 110 for matching installation.

[0065] The filter element 200 is formed by integrally injecting the grille 201 and the filter screen. Since the air outlet extends to different sides of the housing 100, the filter element 200 is formed with a bending section 203 after injection molding. The cross-sectional shape of the filter element 200 is roughly L-shaped, so that the filter element 200 can completely cover the air inlet 110. It can be understood that the filter element 200, as a single component, can reduce the number of parts. The grille 201 and the filter screen can be installed by simply assembling the filter element 200 on the housing 100, effectively improving the assembly efficiency. The filter element 200 is more convenient to disassemble, which is convenient for users to clean and maintain the filter element 200.
