DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1 to 2 , a blade mounting structure in this embodiment includes a motor housing 1. A motor shaft 4 is fixed to the back side of the motor housing 1 and penetrates through the back side of the motor housing 1 and extends to its front side. A connecting seat 3 is fixed to the inner peripheral wall of the inner cavity of the motor housing 1. A glue overflow prevention mechanism 2 is provided inside the motor housing 1. Four support blocks 7 are fixed to the inner side wall of the inner cavity of the connecting seat 3.

[0021] In this example, a plurality of exhaust ducts extending to the back side are opened on the front surface of the connecting seat 3. A first positioning ring 5 is fixed to the back wall of the inner cavity of the motor housing 1, and a second positioning ring 6 is fixed to the back wall of the inner cavity of the motor housing 1.

[0022] Please refer to Figure 3, in order to recycle the glue, the glue overflow prevention mechanism 2 in this embodiment includes a magnet main body 201 that is movably attached to the upper surfaces of the four support blocks 7. Glue is applied inside the motor housing 1, and then the magnet main body 201 is pressed down to fix it inside the fan blade and the motor housing 1. Then, the glue is cured to ensure that the magnet is firmly fixed on the fan blade. A glue groove 202 is formed on the back wall of the inner cavity of the motor housing 1 and on the back side of the magnet main body 201. An inclined groove 203 located on the motor housing 1 is formed on the front wall of the inner cavity of the glue groove 202. In order to avoid quality problems caused by glue overflow, the glue groove 202 is designed to intercept the possibly overflowing glue.

[0023] In this example, the magnet main body 201 is movably attached to the front side of the second positioning ring 6. The glue overflow prevention mechanism 2 further includes a flow groove 204 formed on the back side of the motor housing 1. The flow groove 204 is communicated with the inclined groove 203. The glue groove 202 is located between the second positioning ring 6 and the connection seat 3. When the glue flows into the inside of the glue groove 202, it will continue to flow in the direction of the flow groove 204 along the inclined surface of the inclined groove 203 until it flows out through the flow groove 204. At this time, the excess glue can be collected, so as to achieve the purpose of recycling.

[0024] It should be noted that, in order to avoid quality problems caused by glue overflow, the glue groove 202 is designed to intercept the possibly overflowing glue. At the same time, when the glue flows into the inside of the glue groove 202, it will continue to flow in the direction of the flow groove 204 along the inclined surface of the inclined groove 203 until it flows out through the flow groove 204. At this time, the excess glue can be collected, so as to achieve the purpose of recycling.

[0025] It can be understood that in the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific situations. At the same time, those parts not detailed in the present invention are all well-known technologies in the art.

[0026] The working principle of the above embodiment is as follows:

[0027] When the fan blade needs to be installed, glue is applied inside the motor housing 1. Then, the magnet body 201 is pressed down to fix it inside the fan blade and the motor housing 1. Subsequently, the glue is cured to ensure that the magnet is firmly fixed to the fan blade. To avoid quality problems caused by glue overflow, a glue groove 202 is designed to intercept the possibly overflowing glue. At the same time, after the glue flows into the interior of the glue groove 202, it will continue to flow in the direction of the flow-through groove 204 along the inclined surface of the inclined groove 203 until it flows out through the flow-through groove 204. At this time, the excess glue can be collected, thus achieving the purpose of recycling.
