[0002] Interior decoration encompasses room design, renovation, furniture arrangement, and various minor decorative touches. It focuses on the interior of a building, encompassing both the design and construction phase and ongoing renovations after moving in. Furthermore, the concept of "light renovation, heavy decoration" should be gradually established. The more materials used and the more complex the renovation, the more pollutants are likely to occur.

[0003] When doing interior decoration, ventilation devices are usually needed to exhaust the indoor air. However, due to the large amount of dust and small stones left over from the decoration in the house, it is easy to cause stones to fly during ventilation, which is inconvenient to use. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art that there is a lot of dust and small stones left over from decoration in the house, which easily causes the stones to fly away during ventilation, and to propose a ventilation device for indoor decoration.

[0010] In one possible design, the filter assembly includes a filter screen fixedly connected between the inner walls on both sides of the through hole, the filter screen is tilted, and an ash discharge hole is opened at the bottom of the outer frame, and the bottom of the filter screen is used in conjunction with the ash discharge hole.

[0011] In one possible design, the collection assembly includes a collection box, which is located at the bottom of the outer frame. A side panel is fixedly connected to one side of the collection box, and a convex plate is fixedly connected to the top of one side of the side panel, and the convex plate is engaged with the through hole.

[0012] In one possible design, the adjustment assembly includes a rack slidably connected to the inner wall of the cavity, a spring is fixedly connected between the top of the rack and the inner wall of the top of the cavity, and a gear is fixedly sleeved on the outer wall of the rotating shaft, and the gear is meshed with the rack.

[0013] In a possible design, a vertical groove and multiple side grooves are opened on one side of the outer frame, and the multiple side grooves are all located on one side of the vertical groove and connected to the vertical groove. The vertical groove and the multiple side grooves are all connected to the cavity.

[0014] In a possible design, a sliding groove is provided on one side of the rack, a slider is slidably connected to the inner wall of the sliding groove, and a tension spring is fixedly connected between one side of the slider and the inner wall of one side of the sliding groove.

[0015] In a possible design, a toggle rod is fixedly connected to one side of the slider, one end of the toggle rod passes through the vertical slot and is fixedly connected to an operating block, and the vertical slot and the side slot are both used in conjunction with the toggle rod.

[0016] In this application, when ventilation is needed, the fan can be started. At this time, the fan can suck out the indoor air and discharge it through the other side of the through hole. If there are impurities such as small stones, they can be intercepted by the filter. Since the filter is set at an angle, they can slide along the inclined surface of the filter and fall into the collection box through the ash discharge hole at the bottom of the outer frame to complete the collection.

[0017] When the angles of multiple blades need to be adjusted, the operating block can be toggled horizontally, and the operating block drives the toggle rod to move horizontally, and the toggle rod drives the slider to move horizontally and stretch the tension spring. At this time, the toggle rod moves from the inside of the side groove to the inside of the vertical groove, and pushes the operating block vertically upward. The operating block drives the rack to move vertically upward, and the rack drives multiple gears to rotate and squeeze the spring. The gears drive the rotating shaft to rotate, and the rotating shaft drives the blades to rotate, so that the angle of the blades can be adjusted to control the air output.

[0018] Beneficial effects:

[0019] In the present invention, the ventilation device for indoor decoration can adjust the angles of multiple blades by adjusting the components, thereby controlling the air volume. After the angle adjustment is completed, the device can be locked to ensure the stability of the multiple blades.

[0020] In the utility model, the ventilation device for indoor decoration can achieve the effect of filtering and collecting impurities through the filtering component and the collecting component, thereby avoiding the situation of stone splashing, and can quickly collect impurities for easy processing;

[0021] In the utility model, the fan can suck out the indoor air and discharge it through the other side of the through hole. If there are impurities such as small stones, they can be intercepted by the filter and fall into the collection box through the dust discharge hole at the bottom of the outer frame to complete the collection. This can avoid the splashing of stones and can quickly collect impurities for easy processing. By turning the operating block, the shaft will eventually drive the blade to rotate, and then the angle of the blade can be adjusted to control the air output. BRIEF DESCRIPTION OF THE DRAWINGS
