[0002] The ceiling unit is also known as a ceiling unit or an embedded air conditioner. Generally, a mounting groove that is basically the same size as the ceiling unit is pre-opened on the ceiling, and then the ceiling unit is suspended in the mounting groove using the hook provided on the ceiling unit. Since the size of the mounting groove is basically the same as that of the ceiling unit, only an avoidance hole can be opened on the main frame of the ceiling unit. The user extends his hand through the avoidance hole into the mounting groove to install the hook and other fixed structures. After the ceiling unit is installed, the avoidance hole is always in an open state. Since the avoidance hole is connected to the air duct, the hot and humid air outside will come into contact with the gas in the air duct through the avoidance hole, condensation will occur on the fixed structure, and there will be problems such as dripping and corrosion damage of the fixed structure, resulting in low reliability of the ceiling unit.

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] like Figures 1 to 3 The illustrated ceiling machine includes: a main frame 1, provided with a relief hole 11 for installing a fixing structure 2, said fixing structure 2 being used to fix the main frame to the ceiling; and a sealing structure 3, said sealing structure 3 being provided on the main frame 1 and capable of sealing said relief hole 11. By sealing said relief hole 11 with said sealing structure 3, gas within the air duct of the main frame 1 is prevented from coming into contact with gas outside the main frame 1 through said relief hole 11, thereby effectively preventing condensation on the fixing structure 2, thereby avoiding problems such as dripping and rusting of the fixing structure 2, and improving the reliability of the ceiling machine and the user experience.

[0026] It should be noted that the main frame 1 is the primary load-bearing structure of the overhead crane. When the overhead crane is installed, the main frame 1 is used to be mounted on the ceiling. Other structures can be directly or indirectly mounted on the main frame 1 and fixed to the ceiling through the main frame 1. The fixing structure 2 is a structure such as a hook that can fix the main frame 1 to the ceiling.

[0027] In order to facilitate the installation of the fixed structure 2, the skylight machine also includes a mounting plate 4, which is provided on the main frame 1, and the mounting plate 4 is located at the avoidance hole 11. The fixed structure 2 is connected to the mounting plate 4, and the sealing structure 3 has a closed state that closes the avoidance hole 11 and an open state that exposes the mounting plate 4. When installing the fixed structure 2, first connect the fixed structure 2 to the inner wall of the mounting groove, then switch the sealing structure 3 to the open state, expose the mounting plate 4 connected to the main frame 1, and connect the fixed structure 2 to the mounting plate 4 through the avoidance hole 11. When completing the installation of the fixed structure 2, control the sealing structure 3 to switch to the closed state to complete the closure of the avoidance hole 11. When disassembling the main frame 1, first switch the sealing structure 3 to the open state, and then operate the mounting plate 4 and the fixed structure 2 through the avoidance hole 11 to disengage the fixed structure 2 and the mounting plate 4, thereby removing the skylight machine. Figure 1 As shown, the mounting plate 4 and the sealing structure 3 are fixed to the main frame by the same bolt, and the mounting plate 4 is located on the avoidance hole 11. Of course, the mounting plate 4 can also be directly set in the avoidance hole 11, for example, the edge of the mounting plate 4 is interference fit with the inner surface of the avoidance hole 11.

[0028] The mounting plate 4 is provided with a mounting hole, to which the fixing structure 2 is detachably connected. When the sealing structure 3 is in the open state, the sealing structure 3 can expose the mounting hole. The fixing structure 2 is provided with a connecting post, and the mounting hole is provided with an internal thread. The connecting post is provided with an external thread. The internal and external threads cooperate to achieve the connection between the fixing structure 2 and the mounting plate 4.

[0029] The sealing structure 3 includes a first sealing portion 31 and a second sealing portion 32. The first sealing portion 31 is disposed on the main frame 1, and the second sealing portion 32 is movably disposed on the first sealing portion 31. When the sealing structure 3 is in the closed state, the first sealing portion 31 and the second sealing portion 32 cooperate to seal the avoidance hole 11. When the sealing structure 3 is in the open state, at least a portion of the second sealing portion 32 is projected onto the first sealing portion 31. The first sealing portion 31 facilitates the fixation of the sealing structure 3, while the movable arrangement of the second sealing portion 32 facilitates the switching of the sealing structure 3 between the closed state and the open state.

[0030] The movable setting of the second sealing portion 32 may be a flexible segment connection or a hinge connection.

[0031] Optionally, the sealing structure 3 further includes a flexible section 33, which connects the first sealing portion 31 and the second sealing portion 32. The flexible section 33 can drive the second sealing portion 32 to rotate. The flexible deformation of the flexible section 33 enables the rotational connection between the first sealing portion 31 and the second sealing portion 32. The flexible section 33 can also seal the connection between the first sealing portion 31 and the second sealing portion 32, thereby enhancing the sealing effect of the sealing structure 3.

[0032] The sealing structure 3 is provided with a clamping structure, which is clamped and matched with the mounting plate 4. When the sealing structure 3 is in a closed state, the clamping structure is clamped and matched with the mounting plate 4. Figure 2 As shown, the snap-fit ​​mechanism is provided on the second sealing portion 32, and the mounting plate 4 is used to restrict the movement of the second sealing portion 32, thereby preventing the second sealing portion 32 from moving under the action of gravity. When the sealing structure 3 needs to be switched to the open state, the snap-fit ​​mechanism is disengaged from the mounting plate 4, and the second sealing portion 32 can be freely moved.

[0033] Specifically, the snap-fit ​​structure includes a snap-fit ​​34 , a snap-fit ​​protrusion is provided on the mounting plate 4 , and the snap-fit ​​34 is snap-fitted with the snap-fit ​​protrusion.

[0034] To facilitate the movement of the buckle 34, the snap-fit ​​structure further includes a pressing portion 35, which is connected to the buckle 34 and can drive the buckle 34 to move. The user can directly press the pressing portion 35 inside the main frame 1 to drive the buckle 34 to move and release the snap-fit ​​protrusion.

[0035] The pressing portion 35 is provided with an anti-skid structure to prevent the pressing portion 35 from sliding relative to the user's hand during the pressing of the pressing portion 35 and preventing the second sealing portion 32 from being separated from the mounting plate 4 .

[0036] The pressing portion 35 is provided with protrusions and / or grooves, and the protrusions and / or grooves constitute the anti-slip structure.

[0037] The pressing portion 35 is tilted toward the inside of the main frame 1. From the force analysis of the pressing portion 35, when the angle between the pressing portion 35 and the horizontal plane is 90° (that is, the pressing portion 35 and the horizontal plane are perpendicular to each other), the user can save the most effort when squeezing the pressing portion 35. However, due to the limited space inside the skylight machine, it is not convenient for the user to squeeze the pressing portion 35. Therefore, the pressing portion 35 is tilted toward the inside of the main frame 1 to facilitate the user's squeezing operation.

[0038] As an embodiment, the pressing portion 35 and the buckle 34 are both connected to the edge of the second sealing portion 32 away from the first sealing portion 31, and the buckle 34 is located on the side of the second sealing portion 32 facing the fixed structure 2, and the pressing portion 35 is located on the side of the second sealing portion 32 facing the inside of the main frame 1.

[0039] The plane where the pressing portion 35 is located has an angle α with the horizontal plane, and α≥45°. Preferably, the angle range of the angle α is 45° to 75°. The projection of the pressing portion 35 is located on the second sealing portion 32. When pressing the pressing portion 35, the user's squeezing force on the pressing portion 35 is in the direction of the second sealing portion 32. When the snap-fit ​​structure is disengaged from the mounting plate 4, the user can continue to squeeze the pressing portion 35 to drive the second sealing portion 32 to rotate, thereby facilitating the sealing structure 3 to switch to the open state. When the angle α is less than 45°, the installation is inconvenient because the smaller the angle, the greater the force required to be applied; and when the angle α is greater than 75°, the installer has insufficient operating space, making it impossible for the installer to operate the pressing portion 35.

[0040] The plane on which the pressing portion 35 is located forms an angle β with the vertical plane, and β is ≥ 15°. Preferably, the angle β ranges from 15° to 45°. By setting the angle β, the user can more easily squeeze the pressing portion 35, making the squeezing operation of the pressing portion 35 more convenient.

[0041] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
