Description

Technical Field

[0001] This utility model relates to the field of fan and light technology, specifically a combined blowing and suction structure. Background Technology

[0002] A fan light refers to a light fixture that has both air blowing and lighting functions. For example, the earlier application with patent number CN202422245094.0 disclosed a fan light with centralized air outlet. This type of fan light adopts a structure with air intake from the back and air outlet from the front. The air intake and outlet are in the same direction, which means that the back of the light fixture needs to be raised to achieve air intake. In this case, it is difficult to reduce the height of the light fixture, and space is required to adapt to the air intake position during installation. At the same time, it adopts a single fan structure, which has a limited air volume and is difficult to meet the needs of high air volume usage scenarios. Utility Model Content

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Example 1 like Figures 1-4As shown, the combined blowing and suction structure in this embodiment mainly includes a main shell and a fan 20 disposed in the main shell. A partition 103 is disposed inside the main shell 10, which divides the internal space of the main shell 10 into at least two installation spaces 104. The installation spaces 104 have an air inlet 101 and an air outlet 102 on the same side. Here, the main shell 10 is generally circular, and three partitions 103 are evenly disposed every 120° to divide it into three installation spaces for use.

[0015] Correspondingly, a single fan 20 is installed in a single installation space for use. The fan 20 is used to introduce air from the air inlet 101 and discharge it from the air outlet 102. The air enters along the axial direction of the fan 20 and is discharged along the radial direction of the fan 20. The air inlet direction is parallel to and opposite to the air outlet direction. A centrifugal fan structure is adopted.

[0016] The main housing includes an outer cover 11 and an inner housing 12. The outer cover 11 has an opening and includes a bottom wall 111 and a side wall 112 surrounding the bottom wall 111. The side wall 112 is curved to form a basin-like structure. The air outlet 102 is located between the side wall 112 and the inner housing 12. The side wall 112 guides the air discharged radially along the fan 20 to the air outlet 102 for discharge.

[0017] The partition 103 is installed on the inner shell 12 and connected to the outer cover 11. As a result, after the air enters the installation space, it is blocked by the partition 103, the outer shell 11 and the inner shell 12 and can only be discharged from the air outlet 102.

[0018] The inner shell 12 is located at the opening of the outer cover 11. The air inlet 101 is located inside the inner shell 12. There is a gap between the outer edge of the inner shell 12 and the inner wall of the outer cover 11, forming an air outlet 102. Here, the air outlets 102 in the adjacent installation spaces 104 are continuously arranged, that is, the air outlets 102 are connected as a whole and surround the air inlet 101 in a ring. Of course, the shape of the air outlet 102 can be freely selected according to the requirements, such as rectangle, triangle, etc., and is not limited to a certain shape.

[0019] Furthermore, the inner shell 12 has a first air guide edge 121 distributed in a ring, and the air inlet 101 is surrounded by the first air guide edge 121. The first air guide edge 121 is generally arc-shaped, and its end is parallel to the axis of the fan 20.

[0020] Meanwhile, the main housing also includes a protective cover 30 that surrounds the outer cover 11. The protective cover 30 covers the outside of the outer cover 11 to provide protection and decoration. The protective cover 30 is also horizontally positioned corresponding to the bottom wall 111 to facilitate ceiling mounting.

[0021] Example 2 In this embodiment, the overall shape is square, and two partitions 103 are arranged in a cross shape to form four symmetrical installation spaces 104, which can be configured with four fans for use. The air outlet 102 is square and surrounds the space.

[0022] Example 3 In this embodiment, the whole is rectangular and a partition 103 is provided to form two symmetrical installation spaces in the length direction, which can be configured with two fans for use.

[0023] Of course, it should be noted that this utility model is not limited to the above-mentioned shape and number of fans, and different shapes and numbers of fans can be selected according to actual needs.

[0024] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
