Description

Technical Field

[0001] The utility model belongs to the technical field of vacuum cleaners, and in particular relates to an anti-deviating vacuum cleaner motor positioning structure. Background Art

[0002] The vacuum cleaner uses a motor to drive the blades to rotate at high speed, generating negative air pressure inside the sealing pad shell, thereby achieving the effect of sucking up dust. In order to avoid instability when the motor starts, which causes the motor to shift due to vibration, it is often necessary to install a motor positioning structure inside the vacuum cleaner to position the vacuum cleaner motor.

[0003] At present, the existing vacuum cleaner motor positioning structure often uses bolts for positioning and fixing. This positioning method does not have a shock-absorbing function. Since the vacuum cleaner motor rotates very fast, the vibration generated can easily cause the bolts to fall off, causing the motor to shake and shift.

[0004] Therefore, in order to solve the problem that the motor often shifts due to vibration in the existing vacuum cleaner motor positioning structure using bolts to fix the motor, the existing vacuum cleaner motor positioning mechanism is improved to add an anti-shift function to prevent the motor from shaking and shifting. Utility Model Content

[0007] Preferably, the vibration between the motor fan and the positioning assembly is reduced by an anti-deviance assembly to prevent the motor or fan from being deviated due to damage to parts caused by excessive vibration. The motor is used to drive the fan to rotate to change the air pressure inside the vacuum cleaner housing. The positioning assembly limits the installation position of the motor to prevent the motor from shaking inside the vacuum cleaner housing.

The motor room separates the motor fan and other parts, and a dust filter bag is used to prevent dust from entering the motor and fan, thereby preventing damage to the motor and fan.

[0009] Preferably, the positioning structure includes a positioning groove and a positioning column; a positioning groove is opened on the partition, and a positioning column matching the positioning groove is fixedly connected to one side of the fan. The positioning column is inserted into the positioning groove to fix the fan and the motor in the vacuum cleaner housing.

[0010] Preferably, the positioning structure also includes a positioning plate; a positioning plate matching the fan and motor housings is fixedly connected to the vacuum cleaner housing, and the positioning plate can limit the position of the motor and the fan, and restrict the movement of the motor and the fan.

[0011] Preferably, an anchor hole No. 1 is opened on the partition and the fan, a screw rod is inserted into the anchor hole No. 1, a nut is screwed on the screw rod, the screw rod passes through the anchor hole No. 1, and the nut is screwed tightly against the back side of the fan casing to fix the fan on the partition.

[0012] Preferably, the bottom end of the motor is fixedly connected to a mounting seat located in the positioning plate (, a No. 2 anchor hole is opened on the mounting seat, a bolt is inserted into the No. 2 anchor hole, and the bolt passes through the No. 2 anchor hole to fix the motor inside the vacuum cleaner housing, and the fan and the motor are fixed together in the vacuum cleaner housing by welding the housings of the fan and the motor.

The rubber ring can reduce the impact between the positioning column and the positioning groove caused by vibration, the rubber pad can reduce the impact between the positioning plate and the motor caused by vibration, and the sound-absorbing sponge pad can reduce the noise generated by vibration.

[0014] Beneficial effects of the utility model:

[0015] 1. By installing an anti-drift component in the vacuum cleaner housing, the gap between the motor and fan and the vacuum cleaner housing can be filled, which plays a barrier role. The gap filling reduces the range of movement of objects due to amplitude when vibration occurs. At the same time, the anti-drift component is soft in texture, which can reduce the collision between parts, prevent damage due to vibration, and avoid the displacement of the fixed parts of the fixed motor due to vibration;

The positioning column 602 is inserted into the positioning groove 601 to fix the fan 3 and the motor 2 in the vacuum cleaner housing 1, and the positioning plate 603 can limit the position of the motor 2 and the fan 3, and limit the position of the motor 2 and the fan 3.

[0027] See also Figure 4-6 In this embodiment, a No. 1 anchor hole 7 is provided on the partition 4 and the fan 3, a screw rod is inserted into the No. 1 anchor hole 7, a nut is screwed on the screw rod, the bottom end of the motor 2 is fixedly connected to a mounting seat 8 located in the positioning plate 603, a No. 2 anchor hole 9 is provided on the mounting seat 8, a bolt is inserted into the No. 2 anchor hole 9, the anti-deviation component includes a rubber ring 1001, a rubber pad 1002, and a sound-absorbing sponge pad 1003; a rubber ring 1001 is sleeved on the positioning column 602, rubber pads 1002 are bonded to the left and right sides of the mounting seat 8, and a sound-absorbing sponge pad 1003 is attached to the vacuum cleaner housing 1, Pass the screw through the No. 1 anchor hole 7, screw the nut tightly against the rear side of the fan 3 casing, so that the fan 3 is fixed on the partition 4, and the bolt passes through the No. 2 anchor hole 9 to fix the motor 2 inside the vacuum cleaner casing 1.

The rubber ring 1001 can reduce the impact caused by vibration between the positioning column 602 and the positioning groove 601, the rubber pad 1002 can reduce the impact caused by vibration between the positioning plate 603 and the motor 2, and the sound-absorbing sponge pad 1003 can reduce the noise caused by vibration.

[0028] When working, the staff responsible for assembling the vacuum cleaner first aligns the mounting seat 8 with the area circled by the positioning plate 603, places the motor 2 in the vacuum cleaner housing 1, then installs the fan blades of the fan 3 on the transmission element of the motor 2, and welds the housings of the fan 3 and the motor 2, then sleeves the rubber ring 1001 on the positioning column 602, then aligns the positioning column 602 with the positioning groove 601, inserts the positioning column 602 into the positioning groove 601, passes the screw rod through the No. 1 anchor hole 7 on the partition plate 4 and the housing of the fan 3, then tightens the nut to fix it, then inserts the bolt into the No. 2 anchor hole 9 and fixes it, and then plugs the sound-absorbing cotton into the motor room 5;
