Description

Technical Field

[0001] This utility model belongs to the field of vacuum cleaner motor technology, and specifically relates to a waterproof vacuum cleaner motor that can be used for both wet and dry applications. Background Technology

[0002] Vacuum cleaners are generally divided into dry vacuum cleaners and wet / dry vacuum cleaners. Wet / dry vacuum cleaners need to have a waterproof structure for the electrodes. However, the waterproof structure of current waterproof vacuum cleaner motors is relatively simple. Most of them add a waterproof plate between the fan and the motor or install a sealing ring between the bearing on the motor shaft and the waterproof plate, such as the waterproof structure of the vacuum cleaner motor disclosed in CN208176525U.

[0003] However, when encountering small water vapor molecules, water vapor can easily pass through between the bearing and the motor shaft, and a single-layer sealing ring is difficult to achieve a complete seal. In addition, the integrated sealing cover makes it difficult to replace and repair the motor. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a waterproof vacuum cleaner motor that can be used for both wet and dry applications, so as to solve the problems mentioned in the background art.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. Example

[0025] refer to Figures 1 to 4 The waterproof vacuum cleaner motor for both wet and dry use described in this embodiment includes a motor 1, a waterproof shell 2, and a waterproof cover 3. The motor 1 is installed inside the waterproof shell 2. The waterproof cover 3 passes through the motor shaft 11 of the motor 1 and is detachably connected to the open end of the waterproof shell 2 via an installation component 4. An organic shaft waterproof component and a water absorption component are installed between the motor shaft 11 and the waterproof cover 3. A shell cover waterproof component is installed between the waterproof cover 3 and the waterproof shell 2.

[0026] The waterproof assembly for the motor shaft includes a mounting groove 21 located in the middle of the waterproof cover 3. An oil seal 7 is installed in the mounting groove 21. The inner wall of the oil seal 7 is in close contact with the motor shaft 11, and the outer wall of the oil seal 7 is in close contact with the inner wall of the mounting groove 21.

[0027] The water-absorbing assembly includes an integrally formed mounting cylinder 8 on the waterproof cover 3. The mounting cylinder 8 has a second mounting groove 81 that coincides with the axis of the motor shaft 11. The second mounting groove 81 is connected to the first mounting groove 21. A water-absorbing component 9 is installed in the second mounting groove 81.

[0028] The inner diameter of mounting slot 281 on the side closest to motor 1 is not less than the inner diameter of mounting slot 121, so as to facilitate the installation of oil seal 7.

[0029] Preferably, the inner diameter of the side of the second mounting groove 81 away from the motor 1 is larger than the inner diameter of the first mounting groove 21 but smaller than the inner diameter of the second mounting groove 81, so as to facilitate the insertion of the water suction component 9.

[0030] Preferably, the absorbent element 9 is made of sponge 91.

[0031] The waterproof housing assembly includes an annular mounting plate 5 installed on the end of the waterproof cover 3 away from the motor shaft 11. The mounting plate 5 contacts the waterproof housing 2, and a sealing ring 6 is installed between the mounting plate 5 and the inner wall of the waterproof cover 3. The sealing ring 6 is tightly attached to the waterproof housing 2.

[0032] Preferably, the mounting assembly 4 includes multiple sets of snap-fit ​​plates 41 mounted on the waterproof cover 3 and multiple sets of snap-fit ​​plates 43 mounted on the waterproof shell 2. The snap-fit ​​plates 41 and 43 are in one-to-one correspondence and have the same central angle. There is a snap-fit ​​groove 42 between two adjacent sets of snap-fit ​​plates 41.

Then the waterproof shell cover 3 is rotated so that the snap-fit ​​plate 43 is located between the snap-fit ​​plate 41 and the mounting plate 5, thus completing the assembly between the waterproof shell 2 and the waterproof cover 3. The sealing ring 6 seals the waterproof shell 2 and the waterproof cover 3, preventing water vapor from entering the waterproof shell 2 from the side. When water vapor is transferred from the fan to the motor, the water-absorbing part 9 absorbs water, which plays the role of the first layer of sealing. The oil seal 7 further seals the water vapor, preventing water vapor from entering the motor 1 along the motor shaft 11. At the same time, the sponge 9 can also absorb the oil overflowing from the oil seal 7. Example
