[0048] The ceiling-mounted air conditioner, i.e. ceiling-mounted machine, is an air purification or temperature regulation device installed on the ceiling of a room or a place.

[0049] The air inlet panel of the ceiling-mounted machine is provided with an air inlet, and the air inlet grille is installed at the air inlet by screws.

[0050] The air suction machine needs to disassemble the air inlet grid first when cleaning the dust screen and evaporator, and needs to install the air inlet grid after cleaning. When disassembling and assembling the existing air inlet grid, the screws need to be installed and disassembled, thereby causing low disassembly and assembly efficiency of the air inlet grid.

[0051] In order to solve the technical problem of low disassembly and assembly efficiency of the existing air inlet grid, the application provides an air inlet grid structure and an air suction machine. The air inlet grid structure comprises an air inlet grid body and at least one latch assembly: the air inlet grid body is used for covering the air inlet of the air suction machine; the latch assembly comprises a fixed seat, a latch shaft and a limiting strip, the fixed seat is arranged on the air inlet grid body, the fixed seat is provided with a first latch hole and a limiting groove, the latch shaft is arranged in the first latch hole, and the limiting strip is arranged on the latch shaft; the latch shaft is used for being inserted into the air suction machine, so as to connect the air inlet grid body to the air suction machine.

[0052] The latch shaft is configured to rotate the limiting strip into the limiting groove when being inserted into the air suction machine and rotating around its own axis, so as to limit the movement of the latch shaft.

[0053] The air inlet grid structure of the application rotates the limiting strip into the limiting groove by inserting the latch shaft into the air suction machine and rotating the latch shaft around its own axis, so that the latch is locked and inserted into the air suction machine; when the air inlet grid body needs to be disassembled, the limiting strip is rotated to be separated from the limiting groove by rotating the latch shaft, so that the latch shaft is pulled out of the air suction machine, realizing the separation of the air inlet grid body and the air suction machine. At this time, the air inlet grid body can be removed from the air inlet, realizing the disassembly of the air inlet grid body.

[0054] Because the air inlet grid structure of the application only needs to insert the latch shaft into the air suction machine and rotate the latch shaft to make the limiting strip enter the limiting groove to realize the installation of the air inlet grid body, when disassembly is needed, only the limiting strip needs to be separated from the limiting groove by rotating the latch shaft, and then the latch shaft is pulled out of the air suction machine to realize the disassembly of the air inlet grid body. Compared with the existing disassembly and assembly of multiple screws to realize the disassembly and assembly of the air inlet grid, the efficiency of disassembling and assembling the air inlet grid of the application is higher, and the use is more convenient.

[0055] The technical solutions of the application will be described in detail below with reference to the specific embodiments combined with the drawings. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described in detail in some embodiments.

[0072] By adopting the above technical scheme, the fixing seat 210 is fixed on the air inlet grille body 100 more firmly, preventing the fixing seat 210 from falling off the air inlet grille body 100, and similarly, the limiting strip 230 is more firmly fixed on the plug shaft 220.

[0073] In other embodiments, referring to Figure 7 As shown, further comprising a dust filter screen 300, the dust filter screen 300 is detachably connected to one side of the air inlet grille body 100 facing the ceiling-mounted air conditioner 10.

[0074] The existing air inlet grille and the dust filter screen 300 are respectively and separately installed at the air inlet 20 of the ceiling-mounted air conditioner 10, and when the dust filter screen 300 and the evaporator need to be cleaned, the air inlet grille and the dust filter screen 300 need to be respectively and sequentially disassembled.

[0086] The second aspect of the embodiment of the application provides a ceiling-mounted machine 10, which comprises a shell, an air inlet panel 30 arranged on the shell, an air inlet 20 arranged on the air inlet panel 30, and the air inlet grille structure of any of the above embodiments, which is arranged at the air inlet 20.

[0087] The ceiling-mounted machine 10 of the embodiment of the application is provided with the air inlet grille structure of the application, which comprises an air inlet grille body 100 and at least one pin assembly 200. The air inlet grille body 100 is used to cover the air inlet 20 of the ceiling-mounted machine 10. The pin assembly 200 comprises a fixing seat 210, a pin shaft 220, and a limiting strip 230. The fixing seat 210 is arranged on the air inlet grille body 100, the fixing seat 210 is provided with a first pin hole 211 and a limiting groove 212, the pin shaft 220 is arranged in the first pin hole 211, and the limiting strip 230 is arranged on the pin shaft 220. The pin shaft 220 is used to be inserted into the ceiling-mounted machine 10, so as to connect the air inlet grille body 100 to the ceiling-mounted machine 10. The pin shaft 220 is configured to, when being inserted into the ceiling-mounted machine 10 and rotating around the axis thereof, drive the limiting strip 230 to rotate into the limiting groove 212, so as to limit the movement of the pin shaft 220.

[0088] The air inlet grille structure of the application is configured to, after the pin shaft 220 is inserted into the ceiling-mounted machine 10, rotate the pin shaft 220 around the axis thereof, so that the limiting strip 230 rotates into the limiting groove 212, so that the pin is locked and inserted into the ceiling-mounted machine 10. When it is necessary to disassemble the air inlet grille body 100, the pin shaft 220 is rotated, so that the limiting strip 230 rotates out of the limiting groove 212, so as to pull the pin shaft 220 out of the ceiling-mounted machine 10, thereby separating the air inlet grille body 100 from the ceiling-mounted machine 10. At this time, the air inlet grille body 100 can be removed from the air inlet 20, so as to realize the disassembly of the air inlet grille body 100.

[0089] Because the air inlet grille structure of the application is used, only the pin shaft 220 needs to be inserted into the ceiling-mounted machine 10, and then the pin shaft 220 is rotated, so that the limiting strip 230 enters into the limiting groove 212, so as to realize the installation of the air inlet grille body 100. When it is necessary to disassemble, only the pin shaft 220 needs to be rotated, so that the limiting strip 230 is separated from the limiting groove 212, and then the pin shaft 220 is pulled out of the ceiling-mounted machine 10, so as to realize the disassembly of the air inlet grille body 100. Compared with the existing method of disassembling and assembling multiple screws to realize the disassembly and assembly of the air inlet grille, the efficiency of disassembling and assembling the air inlet grille of the application is higher, and the use is more convenient.
