Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a roller brush motor with built-in axial flow fan blades. Background Art

[0002] The roller brush of smart cleaning products is generally small in size and compact in structure. Due to the particularity of the use environment, the shell is generally designed to be a nearly closed structure, and the motor is installed in the cylindrical shell. The motor will continuously generate heat when it is running. If the heat cannot be taken away in time to reach thermal equilibrium, the temperature inside the cylinder may rise to above 100°C, which will not only affect the performance and life of the motor, but may also damage the motor components and the roller brush shell. Therefore, the heat dissipation of the product is an important issue that cannot be ignored. Not only does it require a reasonable design of the product structure when designing the roller brush shell, but as a motor supplier, it is also necessary to design the motor's heat dissipation module in combination with the customer's product structure so that the temperature rise of the product during operation is within the allowable range.

[0003] For motors, the current main solution is to install heat dissipation blades on the motor rotor. The heat dissipation blades are mainly divided into centrifugal blades and axial flow blades according to the direction of air flow. The usual design is to install centrifugal blades on the rotor inside the motor. The end cover and the end face of the iron shell are the air inlet, and the side of the iron shell is the air outlet. The air path is relatively reasonable. However, for the roller brush installed in the cylindrical cavity of the motor, since the cylindrical cavity seals the air outlet on the side wall of the motor, the use of centrifugal blades cannot form a complete air path, which greatly affects the heat dissipation effect of the motor and causes the motor temperature to rise beyond expectations.

[0004] Therefore, it is urgent to design a roller brush motor with built-in axial flow fan blades to overcome the above-mentioned deficiencies of one or more prior arts. Summary of the invention

[0005] The technical solution adopted by the utility model to achieve the above-mentioned technical purpose is: a roller brush motor with built-in axial flow fan blades, characterized in that it includes: a motor body, an end cover is provided at the internal tail end of the motor body, an axial flow fan blade is provided in the end of the motor body provided with the end cover, the axial flow fan blade is connected to the rotor of the motor body, an air outlet is provided on the end cover, and an air inlet is provided at the end of the motor body away from the end cover.

[0006] The beneficial effect of the utility model is as follows: by arranging axial flow fan blades, and respectively arranging an air inlet and an air outlet at both ends of the motor body, the airflow path is changed by the axial flow fan blades to achieve heat dissipation of the motor, and the airflow movement along the motor axis is not hindered by the cylindrical cavity, ensuring that the motor operates under rated load and the temperature will be lower than the expected value, thereby ensuring the stable operation of the motor and effectively extending the service life of the motor.

[0012] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0013] In the description of the embodiments of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms, "connection" and "installation" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. In addition, "connection" can be a direct connection or an indirect connection through an intermediate medium. Among them, "fixed" means that they are connected to each other and the relative position relationship after connection remains unchanged. The directional terms mentioned in the embodiments of the present utility model, such as "inside", "outside", "top", "bottom", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present utility model, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present utility model.

[0014] In the embodiments of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0015] In the embodiment of the present invention, "and / or" is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0016] References to "one embodiment" or "some embodiments" etc. described in this specification mean that one or more embodiments of the utility model include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways. Therefore, the utility model is not limited to the specific embodiments disclosed below.

[0017] like Figure 1-Figure 3 As shown, the utility model provides a roller brush motor with built-in axial flow fan blades, characterized in that it includes: a motor body 10, an end cover 11 is provided at the internal tail end of the motor body 10, an axial flow fan blade 14 is provided in one end of the motor body 10 provided with the end cover 11, the axial flow fan blade 14 is connected to the rotor of the motor body 10, an air outlet 12 is provided on the end cover 11, and an air inlet 13 is provided at one end of the motor body 10 away from the end cover 11.

[0018] Specifically, traditional motors usually use centrifugal fan blades, and through holes corresponding to the centrifugal fan blades are opened on the side walls of the motor, and the heat inside the motor is blown out through the through holes on the side walls to achieve a heat dissipation effect. However, this method is applicable to limited environments. For example, when in some cylindrical cavities, the side walls of the cylindrical cavity will seal the side walls of the motor, so that the heat dissipation effect is reduced. For this reason, the present application specifically changes the traditional centrifugal fan blades into axial flow fan blades 14, and at the same time, an air outlet 12 is opened on the end cover 11 of the motor body 10, and an air inlet 13 is opened at the other end of the motor body 10. The airflow path is changed by the axial flow fan blades 14 to blow out the heat inside the motor body 10. Since the airflow path moves along the axis of the motor body 10, the airflow is not hindered by the cylindrical cavity, so it will not affect the heat dissipation of the motor body, and the temperature of the motor body 10 can be maintained within the expected value, thereby ensuring the stable operation of the motor and effectively extending the service life of the motor.

[0019] To sum up, the utility model sets an axial flow fan blade 14, and sets an air inlet and an air outlet at both ends of the motor body 10 respectively. The axial flow fan blade 14 changes the airflow path to achieve heat dissipation of the motor. The airflow moves along the axis of the motor without being hindered by the cylindrical cavity, ensuring that the motor runs under rated load and the temperature will be lower than the expected value, thereby ensuring the stable operation of the motor and effectively extending the service life of the motor.

[0020] The present invention is not limited to what is described in the specification and implementation modes, and therefore, additional advantages and modifications can be easily realized by those familiar with the art. Therefore, without departing from the spirit and scope of the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details, representative devices, and illustrative examples shown and described herein.
