The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0025] Embodiment 1,

[0026] See also Figures 1 to 3 The utility model discloses a structure for improving the life of a shaded pole motor, which includes a bracket 10, and the bracket 10 includes a mounting seat 11, an oil supply member 13 and an oil storage member 12. A mounting groove 112 is provided on the mounting seat 11, and the oil storage member 12 and the oil supply member 13 are sequentially installed in the mounting groove 112 and connected to the mounting groove 112, and one end of the oil storage member 12 is in contact with the mounting seat 11, and the other end of the oil storage member 12 is sleeved on the outer periphery of the oil supply member 13.

[0027] Based on the above structure, during assembly, the oil storage component 12 can be first installed in the mounting groove 112 and against the groove wall of the mounting groove 112, and the oil supply component 13 can be installed in the mounting groove 112 and located above the oil storage component 12 after the oil storage component 12 is connected to the mounting seat 11. In this way, the oil storage component 12 can cover the bottom and periphery of the oil supply component 13.

[0028] Specifically, when the motors currently on the market are used in products such as air fryers and ovens, their motor shafts need to be installed vertically downward. Since the motor shaft is installed vertically downward, when the product is running, the temperature inside the machine rises. At this time, the lubricating oil in the oil storage felt is diluted, and the lubricating oil will flow downward through the shaft, posing a risk of oil leakage, resulting in the risk of the motor getting stuck and the risk of leaked lubricating oil dripping onto food, posing a safety hazard.

[0029] Therefore, when the bracket 10 in this embodiment is applied to a motor whose motor shaft needs to be installed vertically downward, the motor shaft 30 can be inserted into the bracket 10, and the oil supply part 13 in the mounting seat 11 of the bracket 10 can provide lubricating oil to make the shaft 30 rotate more smoothly. When the motor shaft 30 rotates at high speed and generates high temperature, the oil on the oil supply part 13 is diluted and flows out. At this time, because the bottom and the outer periphery of the oil supply part 13 are covered by the oil storage part 12, the diluted lubricating oil can flow into the oil storage part 12 and be received by the oil storage part 12, so that even if the lubricating oil is diluted, it is not easy to flow out from the outer periphery of the rotating shaft. In this way, the risk of the lubricating oil on the motor shaft 30 flowing downward through the shaft can be reduced, the risk of oil leakage can be reduced, and the safety hazards such as motor jamming and oil leakage can be improved, thereby indirectly improving the service life of the motor.

[0030] It should be noted that the inner diameters of the oil storage member 12 and the oil supply member 13 in this embodiment can be consistent with the inner diameter of the mounting groove 112, so that the two can be mounted in the mounting groove 112 and can be engaged in the mounting seat 11, and the connection is tighter.

[0031] Preferably, the oil supply member 13 can be made of an existing oil absorption gasket, an oil absorption sponge or an oil supply gasket or other oil absorption pads made of other materials that can be used for oil absorption, and the oil storage member 12 can be made of a high temperature resistant elastic gasket.

[0032] Furthermore, a groove 121 is provided on the oil storage member 12 , and the groove 121 extends in the circumferential direction of the oil storage member 12 . The oil supply member 13 is installed in the groove 121 .

[0033] During assembly, a groove 121 can be provided on the oil storage member 12, and the groove 121 can be extended along the circumference of the oil storage member 12. In this way, after the oil supply member 13 is installed in the groove 121, the oil storage member 12 can be covered on the outer periphery of the oil supply member 13, and the bottom of the oil supply member 13 abuts against the bottom wall of the groove 121. Then, when the lubricating oil on the oil supply member 13 is diluted, because the oil supply member 13 is located in the groove 121 on the oil storage member 12, the lubricating oil can flow into the groove body and is not easy to overflow.

[0034] Preferably, the groove 121 may be sized to accommodate the oil supply member 13 and may be integrally formed on the oil storage member 12 .

[0035] Furthermore, the bracket 10 in this embodiment also includes an oil-containing bearing 14, which can be installed in the mounting groove 112 after the oil supply component 13 and the oil storage component 12 are connected to the mounting seat 11, and is pressed on the end of the oil supply component 13 away from the oil storage component 12.

[0036] Specifically, the bracket 10 also includes an oil-containing bearing 14. During assembly, the oil storage member 12 and the oil supply member 13 can be connected to the mounting seat 11 in sequence, and then the oil-containing bearing 14 can be inserted into the mounting groove 112 in the mounting seat 11 so that it can be pressed on the end of the oil supply member 13 away from the oil storage member 12. In this way, when the motor shaft 30 is inserted into the bracket 10, the lubricating oil inside the oil-containing bearing 14 can be used in conjunction with the oil supply member 13 to make the shaft 30 rotate more smoothly.

[0037] It should be noted that the oil-containing bearing 14 in this embodiment can be an existing porous bearing or a self-lubricating bearing.

[0038] Furthermore, a first mounting hole 122 is provided on the oil storage member 12, and the first mounting hole 122 is located in the middle of the groove 121, and a second mounting hole 131 is provided on the oil supply member 13, and the oil-containing bearing 14 is sequentially passed through the second mounting hole 131 and the first mounting hole 122 to be inserted into the mounting seat 11.

[0039] During assembly, by setting the first mounting hole 122 and the second mounting hole 131 on the oil storage member 12 and the oil supply member 13 respectively, the oil-containing bearing 14 can pass through the second mounting hole 131 and the first mounting hole 122 in sequence to be connected to the mounting seat 11. In this way, the oil-containing bearing 14 can be passed through the mounting seat 11, the oil storage member 12 and the oil supply member 13, and the entire structural connection is more tightened.

[0040] Preferably, the first mounting hole 122 and the second mounting hole 131 have the same hole diameter.

[0041] More specifically, the oil storage member 12 in this embodiment is formed of a high temperature resistant rubber ring, and the oil supply member 13 is an oil supply felt.

[0042] Furthermore, the oil-containing bearing 14 is provided with a first through hole 141 which is communicated with the first mounting hole 122 and the second mounting hole 131 . The mounting seat 11 is provided with a second through hole 111 which is used to pass the rotating shaft 30 .

[0043] Specifically, in this embodiment, the oil-containing bearing 14 and the mounting seat 11 are respectively provided with a first through hole 141 and a second through hole 111. Specifically, the first through hole 141 and the second through hole 111 are both connected with the first mounting hole 122 and the second mounting hole 131, and can be connected with the motor shaft 30 when the motor and the bracket 10 are assembled.

[0044] Furthermore, the bracket 10 also includes an elastic gasket 15, which can be sleeved on the end of the shaft 30 away from the mounting seat 11 after the motor shaft 30 passes through the oil-containing bearing 14 and the mounting seat 11, and abuts against the end of the oil-containing bearing 14 away from the oil supply part 13 to lock the shaft 30 and the oil-containing bearing 14.

[0045] Based on the above structure, the bracket 10 also includes an elastic gasket 15. During assembly, after the motor shaft 30 passes through the oil-containing bearing 14 and the mounting seat 11, the elastic gasket 15 can be sleeved on the motor shaft 30, and the shaft 30 and the oil-containing bearing 14 can be locked by the elastic gasket 15.

[0046] Specifically, the elastic gasket 15 can be a rubber gasket or a silicone gasket or other rubber gasket with a certain degree of flexibility and elasticity, so that after being sleeved onto the motor shaft 30, the elasticity of its own material can increase the friction between it and the outer periphery of the shaft 30, so that after being sleeved onto the shaft 30, it can lock the shaft 30 and the oil-containing bearing 14 that abuts against it.

[0047] In addition, due to its own flexibility and elasticity, it can also play a certain shock-absorbing role when the motor shaft 30 is running.

[0048] Furthermore, a third penetration hole 151 is provided on the elastic gasket 15 , and the third penetration hole 151 is arranged corresponding to the first penetration hole 141 and the second penetration hole 111 , and is used to penetrate the rotating shaft 30 .

[0049] Specifically, the elastic gasket 15 is further provided with a third penetration hole 151 for passing the rotating shaft 30 . The diameter of the third penetration hole 151 can be consistent with the diameters of the first penetration hole 141 and the second penetration hole 111 .

[0050] Embodiment 2,

[0051] See also Figure 3 A motor is shown, which includes a rotating shaft 30, a stator 20 and the structure for improving the life of the shaded pole motor in Example 1. One end of the rotating shaft 30 is connected to the stator 20, and the other end of the rotating shaft 30 passes through the bracket 10 and is connected to the outside. The stator 20 is used to drive the rotating shaft 30 to rotate.

[0052] When the motors currently on the market are used in products such as air fryers and ovens, their shafts 30 need to be installed vertically downward. Since the shafts 30 are installed vertically downward, when the product is running, the temperature inside the machine rises, and the lubricating oil in the oil storage felt is diluted. The lubricating oil will flow downward through the shaft, posing a risk of oil leakage, which may lead to the risk of the motor getting stuck and the risk of leaked lubricating oil dripping onto food, posing a safety hazard.

[0053] Therefore, when using the motor in this embodiment, the motor shaft 30 can be inserted into the bracket 10, and the oil supply part 13 in the mounting seat 11 of the bracket 10 can provide lubricating oil to make the shaft 30 rotate more smoothly. When the motor shaft 30 rotates at high speed and generates high temperature, the oil on the oil supply part 13 is diluted and flows out. At this time, because the bottom and the outer periphery of the oil supply part 13 are covered by the oil storage part 12, the diluted lubricating oil can flow into the oil storage part 12 and be received by the oil storage part 12, so that even if the lubricating oil is diluted, it is not easy to flow out from the outer periphery of the rotating shaft. In this way, the risk of the lubricating oil on the motor shaft 30 flowing downward through the shaft can be reduced, the risk of oil leakage can be reduced, the safety hazards such as motor jamming and oil leakage can be improved, and the service life of the motor can be indirectly improved.

[0054] Furthermore, a retaining ring 40 is provided on one end of the rotating shaft 30 away from the bracket 10. The retaining ring 40 is sleeved on the outer circumference of the rotating shaft 30. The retaining ring 40 is connected to an external device to fix the motor stator 20 and support the rotating shaft 30, thereby preventing the motor rotor from swinging or deviating during high-speed rotation, thereby improving the stability and maintenance of the motor operation.

[0055] Preferably, the clamping ring 40 can be a ferrule made of aluminum alloy or steel.

[0056] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
