Abstract
Description
Technical Field
[0001] This utility model belongs to the field of motor equipment technology, specifically relating to a heater motor for noise reduction. Background Technology
[0002] An electric motor (commonly known as a "motor") is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. It is divided into electric motors (symbol M) and generators (symbol G).
[0003] Due to prolonged use, a large amount of dust accumulates on the fan blades of the motor used in the heater, which causes slight noise when it rotates. This reduces the comfort of using the heater and makes cleaning the internal dust very inconvenient. Utility Model Content
[0004] The present invention aims to solve the technical problems existing in the prior art and provide a heater motor for noise reduction.
[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a heater motor for noise reduction, comprising a motor, a main shaft provided at the output end of the motor, an mounting sleeve fitted on the top surface of the main shaft, fan blades provided on the outer ring surface of the mounting sleeve, an outer shell provided on the outer surface of the motor, four mounting protrusions correspondingly provided on the outer ring of the outer shell, a mounting bolt inserted into each mounting protrusion, a cleaning sleeve fitted on the outer ring of the fan blades, a brush inserted into the surface of the cleaning sleeve, the brush inserted into the inner cavity of the cleaning sleeve, a limiting rod provided at the bottom of the cleaning sleeve, the limiting rod slidably inserted into the outer shell, a limiting piece provided at the bottom of the limiting rod, the limiting piece located below the outer shell, two hinge seats symmetrically provided at the bottom of the cleaning sleeve, a small electric telescopic rod provided at the bottom of each of the two hinge seats, the small electric telescopic rod being installed on the outer shell.
[0006] Preferably, each mounting bolt has an auxiliary rubber sleeve fitted on its bottom surface, and each of the four auxiliary rubber sleeves has a washer connected to its bottom. The bottom of the motor is provided with a bottom rubber ring.
[0007] Preferably, the outer shell has a mounting groove corresponding to the small electric telescopic rod, the small electric telescopic rod is installed on the outer shell through the mounting groove, and the top and bottom surfaces of the connection between the small electric telescopic rod and the outer shell are fitted with fixing sleeves.
[0008] Preferably, the top of the motor is provided with a middle sleeve, the outer surface of the middle sleeve is provided with a silent bearing, the surface of the silent bearing is provided with a roller, and the outer wall of the roller is in contact with the inner wall of the mounting sleeve.
[0009] The beneficial effects of this utility model are as follows: By setting a cleaning sleeve on the outer ring of the fan blade, the cleaning sleeve can move up and down around the outer ring of the fan blade through a small electric telescopic rod at the bottom. In conjunction with the rotation of the fan blade, it can clean the dust on the surface of the fan blade. At the same time, the cleaned dust is blown out by the wind generated by the fan blade, achieving a self-cleaning effect. Meanwhile, the brush is made of a relatively hard material, which, together with the annular fan blade, prevents the brush from being caught in the fan blade. At the same time, auxiliary rubber sleeves are fitted on the surface of the mounting bolts of the housing, and washers are connected to the bottom of multiple auxiliary rubber sleeves. When the motor is installed on the housing of the heater, it can reduce vibration. In addition, a middle sleeve is set on the top of the motor, and a silent bearing is set on its surface. A roller is rotated on the outside of the silent bearing. The roller contacts the inner ring of the mounting sleeve, which limits the mounting sleeve and prevents the mounting sleeve from rotating eccentrically after a long period of rotation.
