[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 3As shown, the utility model provides a motor end cover that is easy to install, including a motor end cover 1, a fixing ear 2, a positioning hole 3 and a heat dissipation through hole 4, the fixing ear 2 is fixedly connected to both sides of the motor end cover 1, the positioning hole 3 is opened on the back side of the motor end cover 1, four positioning holes 3 are provided, the heat dissipation through hole 4 is opened on the back side of the motor end cover 1, a plurality of heat dissipation through holes 4 are opened and distributed in a circular shape with equal distances, the rear side of the inner wall of the motor end cover 1 is movably connected with an interception filter ring 5, and the left side of the front side of the interception filter ring 5 is fixedly connected with a clamping component 6.

[0024] refer to Figure 3 The clamping assembly 6 includes an elastic clamping plate 61, which is provided with a plurality of elastic clamping plates 61 and is distributed in a circular shape with equal distances. A clamping groove 62 is opened on the left side of the inner wall of the motor end cover 1, and the clamping groove 62 is provided with a plurality of elastic clamping plates 61 and is distributed in a circular shape with equal distances. The clamping groove 62 is movably connected to the elastic clamping plate 61.

[0025] As a technical optimization solution of the utility model, by setting a snap-in assembly 6, after the intercepting filter ring 5 is installed inside the motor end cover 1, the installation of the intercepting filter ring 5 can be completed by snapping the elastic snap-in plate 61 into the snap-in groove 62, thereby facilitating the user to install the intercepting filter ring 5.

[0026] refer to Figure 3 The bottom of the inner wall of the clamping groove 62 is fixedly connected with an inclined plate 7, and the inclined plate 7 is movably connected to the elastic clamping plate 61.

[0027] As a technical optimization scheme of the utility model, by setting the inclined plate 7, the intercepting filter ring 5 will contact the inclined plate 7 when driving the elastic snap-in plate 61 to rotate. When the inclined plate 7 contacts the elastic snap-in plate 61, the snap-in plate will elastically deform along with the inclination of the inclined plate 7, so that the elastic snap-in plate 61 will separate from the snap-in groove 62, thereby facilitating the user to disassemble and replace the intercepting filter ring 5.

[0028] refer to Figure 3 A positioning groove 8 is provided on the rear side of the inner wall of the motor end cover 1 , and a positioning ring 9 is fixedly connected to the back of the interception filter ring 5 , and the positioning ring 9 is movably connected to the positioning groove 8 .

[0029] As a technical optimization scheme of the utility model, by setting the positioning groove 8 and the positioning ring 9, the positioning groove 8 and the positioning ring 9 can be used in combination to position the intercepting filter ring 5, which is convenient for the user to install the intercepting filter ring 5 and can further reduce the movable gap between the intercepting filter ring 5 and the motor end cover 1.

[0031] As a technical optimization solution of the utility model, by providing an installation spring plate 10 and a handle 11, the handle 11 on the installation spring plate 10 can facilitate the user to rotate the intercepting filter ring 5, thereby facilitating the installation or removal of the intercepting filter ring 5.

[0032] refer to Figure 3 A rubber fitting pad 12 is fixedly connected to the top of the left side of the mounting spring plate 10 , and the rubber fitting pad 12 is movably connected to the inner wall of the motor end cover 1 and fits tightly.

[0033] As a technical optimization solution of the utility model, by providing a rubber fitting pad 12, the use of the rubber fitting pad 12 can increase the friction between the mounting spring plate 10 and the motor end cover 1, thereby avoiding the self-rotation of the interception filter ring 5 under non-human conditions.

[0035] As a technical optimization solution of the present invention, by providing the rubber fitting pad 12 with a wear-resistant rubber material, the use of the wear-resistant rubber material can increase the wear resistance of the rubber fitting pad 12 , thereby extending the service life of the rubber fitting pad 12 .

[0036] The working principle and use process of the utility model are as follows: when in use, the intercepting filter ring 5 is placed into the interior of the motor end cover 1 by installing the handle 11 on the spring plate 10, so that the positioning ring 9 is inserted into the positioning groove 8 and the elastic snap-in plate 61 can be snapped into the snap-in groove 62, so that the intercepting filter ring 5 is installed inside the motor end cover 1, so that the intercepting filter ring 5 can filter the air entering the interior of the motor end cover 1 through the heat dissipation through hole 4, and prevent the air from carrying dust into the interior of the motor end cover 1, thereby achieving the filtering effect.

[0037] To sum up: this kind of motor end cover is easy to install. By setting an interception filter ring 5, the interception filter ring 5 can filter and intercept dust in the air entering the inside of the motor end cover 1 through the heat dissipation hole 4, which solves the problem of increasing the heat dissipation effect of the motor end cover through the heat dissipation hole during use. However, no filtering structure is set, so that air carrying dust enters the inside of the motor through the heat dissipation hole, which will affect the normal operation of the motor for a long time and increase the loss of the motor.
