Description

Technical Field

[0001] The present invention relates to the technical field of vacuum cleaning, and particularly to a vacuum cleaner motor with a bearing moisture-proof function. Background Art

[0002] In the vacuum cleaner industry, there are approximately 50 million to 80 million wet and dry vacuum cleaners every year, which means it can vacuum and absorb water simultaneously. All wet and dry vacuum cleaners have a serious defect, that is, the bearings of the motor are very easy to break. Because when this type of motor absorbs water, although most of the water will be isolated by the filter of the vacuum cleaner, water vapor cannot be completely isolated. A part of the water vapor will enter the blower part of the motor. For all such motors, the water vapor and the motor adopt a double air duct to isolate, but the bearings cannot be completely isolated, and the water vapor will pass through the bearings from the gap between the outer ring and the inner ring of the bearings, resulting in bearing damage. Therefore, it is very necessary to design a vacuum cleaner motor with a bearing moisture-proof function that has a permanent waterproof function for the bearings and can adjust the working state according to the detection result of the water vapor volume.

Thus, different working states of the heat conduction sheet and the cooling mechanism are triggered by the liquid cylinder. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0023] Please refer to Figures 1-5 , the present invention provides a technical solution: a vacuum cleaner motor with a bearing moisture-proof function, including a housing 1. A transmission mechanism is installed inside the housing 1. A cooling mechanism is arranged on one side of the transmission mechanism. The cooling mechanism is located inside the housing 1. An air intake mechanism is arranged below the transmission mechanism. The air intake mechanism includes an air inlet pipe 5. A inlet box 26 is installed on the right side of the air inlet pipe 5. A detection mechanism is arranged inside the inlet box 26. Connect the power supply 37 and turn on the switch 36 of the vacuum cleaner. The motor of the vacuum cleaner drives the transmission mechanism to start working. The transmission mechanism triggers its air intake mechanism, enabling the vacuum cleaner to collect external garbage and water vapor, and realizing the waterproof function inside the bearing two 34 through the inverted impeller 13 and air flow pressure, so as to effectively extend the service life of the bearing two 34. The detection mechanism detects the amount of water vapor entering to facilitate the classification treatment of different levels of water vapor, and at the same time judges the power consumed inside the motor according to its water inflow. When the internal device consumes a large amount of power, the cooling mechanism is triggered to further cool the inside of the motor.

[0024] The transmission mechanism includes a cover plate, which is threadedly connected to the inside of the housing 1. In the middle of the inside of the housing 1, a rotating shaft 3 is provided. At the upper end of the rotating shaft 3, a first bearing 8 is installed. The outside of the first bearing 8 is fixed in the middle of the cover plate. An air inlet 4 is provided between the first bearing 8 and the cover plate. In the middle of the rotating shaft 3, a rotor 9 is fixed. Outside the rotor 9, a stator 10 is provided. Below the stator 10, a support plate 38 is provided. The support plate 38 is fixed to the inside of the housing 1. A number of through holes are provided on the surface of the support plate 38. The cover plate supports the rotating shaft 3 through the first bearing 8. When the switch 36 is closed, the rotating shaft 3 drives the rotor 9 to rotate. The stator 10 supports the periphery of the rotor 9. The stator 10 and the rotor 9 interact with each other, thereby triggering the dust suction process inside the device. When the rotating shaft 3 starts to rotate, air flows in from the air inlet 4 into the inside of the housing 1 and is output from the through holes through the pores of the stator 10. When the stator 10 and the rotor 9 are working, the air flow can effectively dissipate heat from the stator 10 and the rotor 9 that generate heat. The support plate 38 supports the rotating shaft 3 through a second bearing 34. This effectively enhances the stability between the components inside the motor when the rotating shaft 3 rotates. At the same time, the air flow through the internal through holes applies a downward thrust to the water vapor transmitted by the impeller 13 below, effectively preventing the water vapor from entering the inside of the second bearing 34, and effectively preventing the water vapor from entering the inside of the second bearing 34 to extend its service life.

[0025] Below the rotor 9, a second bearing 34 is installed. The outside of the second bearing 34 is fixedly connected to the middle of the support plate 38. The left side of the air inlet pipe 5 is fixed to the surface of the housing 1 and is internally connected. At the bottom end of the rotating shaft 3, an impeller 13 is fixed. The impeller 13 is inverted. An air inlet is provided inside the impeller 13. The air inlet of the impeller 13 faces the second bearing 34. Outside the impeller 13, a wind cover 2 is installed. A number of ventilation openings are provided on the surface of the wind cover 2. At the bottom of the wind cover 2, a chassis is provided. The chassis supports the entire device. Compared with a common impeller 13, the impeller 13 inside this device adopts an inverted design and a special right-side pipe air inlet method. The dust suction air flow enters the inside of the inverted impeller 13 through the air inlet pipe 5. Under the guidance of the impeller 13 and the action of the downward output air flow through the through holes, the inhaled water vapor flows downward and is discharged from the ventilation openings on the surface of the wind cover 2. Such a design prevents the water vapor from penetrating into the inside of the second bearing 34, protects the inside of the second bearing 34, and at the same time, through the design of the right-side air inlet pipe 5, extends the air inlet pipe below the device, effectively reducing the noise pollution generated when the motor works.

[0026] A dust suction pipe is fixed to the right side of the inlet box 26. The other end of the dust suction pipe is provided with a dust suction port 6. A heat conducting sheet 7 is arranged inside the dust suction port 6. A filter disc 27 is arranged on the right side of the inlet box 26. A liquid storage cavity 29 is arranged below the left side of the filter disc 27. A U-shaped pipe 28 is arranged between the upper end of the liquid storage cavity 29 and the lower end of the filter disc 27. When the motor starts to work, the dust suction port 6 is in full contact with the external water vapor and sundries. The inhaled water vapor is in full contact with the filter disc 27 through the dust suction pipe. At the same time, fine holes are arranged on both sides of the filter disc 27. Only extremely fine water vapor can enter the inside of the inlet box 26 through the fine holes. Most of the water vapor accumulates inside the filter disc 27 after passing through the fine holes on the right side of the filter disc 27, and the water vapor seeping out from the left fine holes is distributed in a fixed proportion to the water vapor accumulated inside the filter disc 27. When the height of the water vapor accumulated inside the filter disc 27 is higher than the height of the left pipe orifice of the U-shaped pipe 28, a siphon phenomenon occurs inside the liquid storage cavity 29. The water vapor accumulated inside the filter disc 27 forms a liquid and enters the inside of the liquid storage cavity 29 through the right pipe orifice of the U-shaped pipe 28. When the water content at the place where dust suction is carried out is relatively low, that is, the level of the inhaled water vapor is mild, the liquid storage cavity 29 directly collects the inhaled water vapor. The clamping ball 31 has always been located inside the clamping orifice 30. In this way, the detection and collection of mild water vapor volume are effectively realized, the entry of water vapor inside the impeller 13 is reduced, and at the same time, the mild-level water vapor volume cannot trigger the subsequent heat conducting sheet 7 and the cooling mechanism, reducing the power consumption inside it.

[0027] A clamping orifice 30 is opened at the bottom of the liquid storage cavity 29. A clamping ball 31 is installed inside the clamping orifice 30. A group of brackets 33 are installed at the bottom on the right side inside the inlet box 26. A convex block 32 is fixed between the group of brackets 33. The outside of the liquid storage cavity 29 is slidably connected with the brackets 33. When the level of the entered water vapor is moderate, water continuously accumulates inside the filter disc 27, and the inside of the liquid storage cavity 29 is filled with water vapor. At the same time, affected by gravity, the liquid storage cavity 29 drives the internal water vapor to slide downward along the inner wall of the brackets 33 and contacts the lower convex block 32. The convex block 32 on both sides between the brackets 33 supports the liquid storage cavity 29 filled with water vapor. At this time, the convex block 32 exerts an upward thrust on the lower surface of the liquid storage cavity 29 in contact with it. Affected by the thrust, the clamping ball 31 moves out of the clamping orifice 30, and the liquid output volume below the clamping orifice 30 is equal to the liquid input volume above the liquid storage cavity 29. Thus, when the water vapor volume entering the filter disc 27 is at a medium level, the liquid storage cavity 29 becomes a water vapor flow transfer station. When the inside of the filter disc 27 continues to admit water, an equal amount of water vapor flows out from the inside of the liquid storage cavity 29 and enters the lower cavity inside the liquid cylinder one 23. Through such a setting, the liquid storage cavity 29 can automatically detect and adjust the water vapor entry volume in a timely manner, effectively preventing the filter disc 27 from accumulating too much water vapor and overflowing.

[0028] The interior of the inlet box 26 is respectively provided with a first hydraulic cylinder 23 and a second hydraulic cylinder 24. The interiors of the first hydraulic cylinder 23 and the second hydraulic cylinder 24 are both provided with upper and lower chambers. The interiors of the first hydraulic cylinder 23 and the second hydraulic cylinder 24 are both slidably connected with push plates. The upper chambers of the first hydraulic cylinder 23 and the second hydraulic cylinder 24 are both filled with gas. The middle of the push plate is connected with a baffle cloth 22 by a spring. The bottom of the liquid storage chamber 29 is connected to the lower chamber of the first hydraulic cylinder 23 through a pipeline. A baffle block 25 is arranged inside the upper chamber of the first hydraulic cylinder 23. The right side of the baffle block 25 is connected to the lower chamber of the second hydraulic cylinder 24 through a pipeline. When it is detected that the water vapor quantity level is moderate, the water vapor inside the liquid storage chamber 29 enters the lower chamber of the first hydraulic cylinder 23 through the pipeline below. The water vapor in the lower chamber of the first hydraulic cylinder 23 exerts an upward thrust on the push plate inside the first hydraulic cylinder 23, and when it contacts the lower side of the baffle block 25, it is the maximum value in the moderate range of the water vapor quantity. Under this thrust, the gas in the upper chamber of the first hydraulic cylinder 23 enters the lower chamber of the cylinder 11 through the pipeline, thereby triggering the subsequent cooling mechanism and the heat conducting sheet 7 to work. When the water vapor quantity level entering the filter disc 27 is high, the liquid storage chamber 29 still maintains the previous process. Only the water vapor entering the lower chamber of the first hydraulic cylinder 23 will exert an upward thrust on the baffle block 25. The baffle block 25 is pushed open under the action of the thrust. The water vapor in the lower chamber of the first hydraulic cylinder 23 enters the lower chamber of the second hydraulic cylinder 24 through the pipeline on the right side of the baffle block 25. The water vapor entering the second hydraulic cylinder 24 exerts an upward thrust on the push plate inside it. The gas in the upper chamber of the second hydraulic cylinder 24 enters the lower chamber of the cylinder 11 under the action of the extrusion force, so as to facilitate more effective cooling of the interior of the device subsequently. The baffle cloth 22 is made of a water-absorbing material. When the water vapor quantity level is low, the baffle cloth 22 directly absorbs the water vapor passing through the pores of the filter disc 27, thereby reducing the amount of water vapor entering the impeller 13 and effectively protecting the second bearing 34. When the detected water vapor quantity level is moderate, the push plate inside the first hydraulic cylinder 23 pulls the baffle cloth 22 open to a certain height through the spring during the rising process, which can effectively prevent the water vapor accumulated on the baffle cloth 22 from becoming liquid water flow and flowing into the impeller 13, which is likely to cause damage to the interior of the motor. When the water vapor quantity level is high, the push plate inside the second hydraulic cylinder 24 continues to pull the baffle cloth 22 upward to open during the rising process. Thus, the baffle cloth 22 can be opened to a larger angle according to the water vapor entry quantity level, effectively protecting the interior of the device.

[0029] A cylinder 11 is externally installed on the stator 10. The cylinder 11 is fixed to the upper surface of the support plate 38. The interior of the cylinder 11 is divided into upper and lower chambers. A piston 19 is slidably connected inside the cylinder 11. The upper chamber of the cylinder 11 is filled with liquid nitrogen. The upper chambers of the first liquid cylinder 23 and the second liquid cylinder 24 are both connected to the lower chamber of the cylinder 11 through pipelines. When the water vapor level is mild, the gas inside the first liquid cylinder 23 does not enter the lower chamber of the cylinder 11, so the cooling mechanism is not triggered. The motor can achieve the heat dissipation effect on the stator 10 and the rotor 9 only by the air flow entering through the air inlet 4. When the water vapor level is moderate, the gas inside the first liquid cylinder 23 is pushed upward by the push plate into the lower chamber of the cylinder 11. The gas entering the lower chamber of the cylinder 11 exerts an upward force on the piston 19. The liquid nitrogen in the upper chamber of the cylinder 11 enters the inside of the ball block 12 under the extrusion force of the piston 19 to facilitate the subsequent cooling process inside the motor. When the water vapor level is high, the gas in the upper chamber of the second liquid cylinder 24 enters the lower chamber of the cylinder 11 through the pipeline. The piston 19 continues to move upward and continuously squeezes the liquid nitrogen into the inside of the ball block 12 to facilitate the continuous cooling of the internal device. Due to the different amounts of water vapor entering and the operation of the heat conduction sheet 7, the power consumed inside the motor is also different. Thus, the cooling control can be carried out according to different water vapor detection amounts, effectively extending the service life of the device.

[0030] A clamping block 21 is fixed to the left side of the inlet box 26. The upper end of the baffle cloth 22 is fixed to the upper end inside the clamping block 21. A ball block 12 is installed above the stator 10. The ball block 12 is of a hollow structure. A number of air holes are provided on the upper surface of the ball block 12. The clamping block 21 and the right end of the air inlet pipe 5 are of a detachable structure. When the motor stops working, the clamping block 21 can be removed in time and the baffle cloth 22 inside it can be dried for the next use. When the liquid nitrogen in the cylinder 11 is squeezed into the inside of the ball block 12, in order to prevent the liquid nitrogen from damaging the device in liquid form after being extruded from the cylinder 11, the liquid nitrogen first enters the inside of the ball block 12 and is converted into nitrogen at room temperature and output from the air holes. The nitrogen passes through the inside of the rotor 9 and the stator 10 under the guidance of the air flow direction, thus effectively further cooling the stator 10 and the rotor 9 inside the motor on the basis of the initial air flow cooling.

[0031] An insulating rod 20 is fixed to the upper end face of the piston 19. Above the insulating rod 20, a resistor housing 14 is installed. Inside the resistor housing 14, a resistor block 18 is installed. Inside the resistor housing 14, a first energizing groove 15 and a second energizing groove 16 are respectively provided. A partition plate 17 is provided between the first energizing groove 15 and the second energizing groove 16. The second energizing groove 16 is electrically connected to the heat conducting sheet 7. When the water vapor level is mild, the piston 19 does not move. When the water vapor level is moderate, the gas inside the upper cavity of the first liquid cylinder 23 is squeezed into the inside of the steel cylinder 11. This gas exerts an upward thrust on the piston 19. The piston 19 drives the insulating rod 20 to move upward. The top end of the insulating rod 20 is in full contact with the bottom of the upper resistor block 18 above, and pushes the resistor block 18 to slide upward. When a part of the resistor block 18 enters the inside of the second energizing groove 16, an electric current passes through the heat conducting sheet 7 and starts to heat up. The heated heat conducting sheet 7 dries the moisture at the dust collection place, thereby reducing the entry of water vapor from the source. When the push plate inside the second liquid cylinder 24 pushes the gas in the upper cavity into the inside of the steel cylinder 11, the piston 19 continues to push the insulating rod 20 to slide upward under the action of the gas. The insulating rod 20 drives the resistor block 18 to move upward again. The heat conducting sheet 7 continues to heat up. At the same time, the volume of the resistor block 18 inside the second energizing groove 16 becomes larger, and the current flowing through the heat conducting sheet 7 will decrease. Thus, the power consumed by the heat conducting sheet 7 will be reduced. Thus, while drying the surrounding water vapor, the energy-saving effect inside the device is achieved.

[0032] A set of terminal posts 35 are installed outside the housing 1. A power supply 37 and a switch 36 are provided outside the housing 1. The inside of the terminal posts 35 is electrically connected to the inside of the resistor housing 14. The partition plate 17 is located inside the resistor housing 14 and breaks the connection between the first energizing groove 15 and the second energizing groove 16, effectively realizing different proportional resistor distributions of the resistor block 18 in the groove, enabling the heat conducting sheet 7 to achieve the energy-saving effect under the normal current-carrying state. And the terminal posts 35 are electrically connected to the power supply 37, effectively realizing the normal rotation of the rotating shaft 3 inside the motor, thereby realizing the dust collection effect of the device.
