Description

Technical Field

[0001] This utility model relates to a DC motor with an external shroud, belonging to the field of DC motor technology. Background Technology

[0002] A DC motor is a rotating electric machine that can convert DC electrical energy into mechanical energy or vice versa. It mainly consists of a stator, a rotor, and a commutator. The stator is the stationary part of the motor, usually made of stacked silicon steel sheets with coils embedded inside. The rotor is the rotating part of the motor, consisting of a shaft, a rotor core, and a commutator. The commutator is the conductive part of the motor, used to convert DC electrical energy into mechanical energy.

[0003] DC motors are usually equipped with an external shroud to protect the motor's interior from external contaminants and prevent unnecessary damage. Existing external shrouds are usually installed using screws, which makes the installation and removal process relatively troublesome and replacement cumbersome. Therefore, we provide a DC motor with an external shroud. Utility Model Content

[0004] To solve the above problems, this utility model provides a DC motor with an external shroud, and the specific technical solution is as follows:

[0005] A DC motor with an external shroud includes a DC motor body, a fan connected to the right side of the DC motor body, a slot formed on the right side of the DC motor body, two movable slots formed on the outer surface of the DC motor body, a sliding plate provided inside each of the two movable slots, two cavities formed on the inner wall of the DC motor body, an external shroud assembly provided inside the slot, two positioning blocks connected to the outer surface of the external shroud assembly, positioning openings formed on the outer surfaces of the two positioning blocks, and the sides of the two sliding plates that are far apart from each other passing through the positioning openings and extending into the cavity.

[0006] Preferably, the outer shroud assembly includes a connecting cylinder, and a filter shell is threadedly connected to the outer surface of the connecting cylinder.

[0007] Preferably, the outer surface of the DC motor body is connected to a mounting base, and the outer surface of the mounting base has two sets of threaded holes.

[0008] Preferably, the outer surface of the fan is connected to a connecting shaft, one end of which is connected to a cleaning brush, and the outer surface of the cleaning brush is in contact with the filter housing.

[0009] Preferably, the outer surfaces of both slide plates are connected to actuating blocks, and the outer surfaces of both actuating blocks penetrate the movable slot and extend to the outside of the DC motor body.

[0010] Preferably, the inner walls of both cavities are connected to magnets, and the sides of the two sliding plates that are far apart from each other are connected to the outer surfaces of the magnets.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This DC motor with an outer shroud positions the outer shroud assembly by inserting it into a slot and rotating it within the slot, which moves the positioning block to a designated position. The sliding plate then moves through the positioning port into the cavity, completing the positioning of the outer shroud assembly. This device has a simple structure and is easy to install and disassemble, facilitating the replacement of the outer shroud assembly and solving the problems of cumbersome disassembly and replacement processes in existing systems.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] 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.

[0021] Please see Figure 1-5 In this utility model, a DC motor with an outer fan cover includes a DC motor body 1. A fan 3 is connected to the right side of the DC motor body 1. A slot 4 is provided on the right side of the DC motor body 1. Two movable slots 6 are provided on the outer surface of the DC motor body 1. Slide plates 5 are provided inside the two movable slots 6. Two cavities 15 are provided on the inner wall of the DC motor body 1. An outer fan cover assembly 2 is provided inside the slot 4. Two positioning blocks 9 are connected to the outer surface of the outer fan cover assembly 2. Positioning holes 12 are provided on the outer surface of the two positioning blocks 9. The sides of the two slide plates 5 that are far apart from each other pass through the positioning holes 12 and extend into the cavity 15. By providing a slot 4, it is easy to fasten the outer fan cover assembly 2 with the positioning blocks 9. By providing a movable slot 6, it is easy for the slide plates 5 to slide through the slots and be positioned. By providing a cavity 15, it is easy to store the slide plates 5 and prevent one end of the slide plates 5 from tilting up. By providing a positioning hole 12, it is easy for the slide plates 5 to pass through the positioning blocks 9, thereby facilitating the positioning of the outer fan cover assembly 2.

[0022] The outer fan shroud assembly 2 includes a connecting cylinder 201, on the outer surface of which a filter housing 202 is threadedly connected. The threaded connection between the connecting cylinder 201 and the filter housing 202 facilitates the replacement of the filter housing 202 independently. The outer surface of the DC motor body 1 is connected to a mounting base 7, which has two sets of threaded holes 8 on its outer surface, allowing the DC motor body 1 to be installed with screws. The outer surface of the fan 3 is connected to a connecting shaft 10, one end of which is connected to a cleaning brush 11. The outer surface of the cleaning brush 11 contacts the filter housing 202. The connecting shaft 10 rotates with the fan 3, thereby driving the cleaning brush 11 to clean the dust on the filter housing 202.

[0023] Both slide plates 5 have actuating blocks 13 connected to their outer surfaces. The outer surfaces of both actuating blocks 13 penetrate the movable slot 6 and extend to the outside of the DC motor body 1. By setting the actuating blocks 13, the slide plates 5 can be easily driven to slide. The inner walls of both cavities 15 are connected to magnets 14. The sides of the two slide plates 5 that are far apart from each other are connected to the outer surfaces of the magnets 14. By magnetically connecting the slide plates 5 and the magnets 14, the slide plates 5 can be positioned to prevent them from sliding.

[0024] The working principle of this utility model is as follows:

[0025] When in use, first insert the outer hood assembly 2 into the slot 4, then rotate the outer hood assembly 2 to move the positioning block 9 to the designated position, and then move the sliding plate 5 so that the sliding plate 5 passes through the positioning port 12 and is inserted into the cavity 15, thereby positioning the outer hood assembly 2 to complete the installation. When disassembling, move the sliding plate 5 to disengage it from the cavity 15 and the positioning block 9, and then rotate the outer hood assembly 2 to move the positioning block 9 to the designated position to complete the disassembly.
