AI Technical Summary
The installation method of existing ventilation fans requires the preset spacing between the air inlet and the host according to the thickness of the ceiling surface, resulting in poor visual effects or inability to adapt to the ceiling surface of different thicknesses, and hidden installation cannot be achieved.
A hidden ventilation fan is designed. By adding a panel mount seat and a panel embedding ring on the cover plate, threaded connections are used to achieve a close fit between the panel and the cover plate, adapting to different ceiling thicknesses, and forming a hidden installation.
The panels are closely fitted with the ceiling, adapting to ceiling surfaces of different thicknesses, improving installation flexibility and aesthetics, and avoiding visual defects of the raised or countersunk structure.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of household appliances, in particular to a hidden ventilation fan. Background Art
[0002] A ventilation fan is an air conditioning appliance that uses a motor to rotate blades, creating airflow and exchanging air between indoor and outdoor spaces. Also known as a ventilator, a ventilation fan removes indoor air and introduces outdoor air. It is widely used in homes and public spaces.
[0003] At present, ventilation fans are usually installed on the ceiling surface, with mounting holes opened on the ceiling surface, the main unit of the ventilation fan is installed above the ceiling surface, and the air inlet of the ventilation fan is installed in the mounting holes on the ceiling surface. This installation method requires pre-setting the distance between the air inlet and the ventilation fan main unit according to the ceiling surface to adapt to the thickness of the ceiling surface. If the distance is greater than the thickness of the ceiling surface, the protrusion of the air inlet will cause extremely poor visual effects after installation. If the distance is less than the thickness of the ceiling surface, it cannot be installed or the mounting port needs to be additionally opened into a countersunk hole structure. Therefore, a hidden ventilation fan that can adapt to different ceiling surfaces is an urgently needed product on the market. Utility Model Content
[0004] In order to solve the above problems, the utility model provides a hidden ventilation fan, including a box body, a cover plate and a panel. The top of the box body is covered with a cover plate, the cover plate is groove-shaped, and a cover plate air inlet is opened in the center of the cover plate corresponding to the fan inside the box body, and the air inlet is provided with a panel mounting seat; the panel includes a panel body, and a panel air inlet is opened in the center of the panel body corresponding to the cover plate air inlet, and the panel air inlet is provided with a panel embedding ring, and the panel embedding ring is embedded in the panel mounting seat to connect the panel and the cover plate.
[0005] Furthermore, the inner wall of the panel mounting seat and the outer wall of the panel embedding ring are provided with mutually matching threads, and the panel embedding ring and the panel mounting seat are threadedly connected to each other.
[0006] Furthermore, the diameter of the panel body is larger than the diameter of the panel embedding ring, and during installation, the edge of the panel body abuts against the surface to be installed.
[0007] Furthermore, a ventilation port is provided on the side wall of the box.
[0008] The beneficial effect of the present invention is that a panel mounting seat is added to the cover plate, and a panel embedding ring is provided corresponding to the panel. The two are screwed to each other through threads, which can flexibly adapt to the thickness of the ceiling surface and ensure that the panel and the ceiling fit tightly to form a hidden installation.

In addition, it should be noted that it should be understood that the specific embodiments described herein are merely used to explain the present application and are not intended to limit the actual scope of protection. All raw materials used in the following examples are commercially available products.
[0013] Example 1
[0014] like Figure 1-Figure 2 As shown, a hidden ventilation fan includes a box body 1, a cover plate 2 and a panel. The top of the box body 1 is sealed with a cover plate 2, the cover plate 2 is groove-shaped, and a cover plate air inlet 3 is opened in the center of the cover plate 2 corresponding to the internal fan of the box body 1. The cover plate air inlet 3 is provided with a panel mounting seat 4; the panel includes a panel body 5, and a panel air inlet 6 is opened in the center of the panel body 5 corresponding to the cover plate air inlet 3. The panel air inlet 6 is provided with a panel embedding ring 7, and the panel embedding ring 7 is embedded in the panel mounting seat 4 to connect the panel and the cover plate 2.
[0015] The inner wall of the panel mounting base 4 and the outer wall of the panel insert ring 7 are provided with mating threads, and the panel insert ring 7 and the panel mounting base 4 are screwed together. The diameter of the panel body 5 is larger than that of the panel insert ring 7, and during installation, the edge of the panel body 5 abuts the surface to be installed. The side wall of the box body 1 is provided with a ventilation port 8.
[0016] The utility model adds a panel mounting seat 4 on the cover plate 2, and a panel embedding ring 7 is correspondingly provided on the panel. The two are screwed to each other through threads, which can flexibly adapt to the thickness of the ceiling surface and ensure that the panel and the ceiling fit tightly to form a hidden installation.
