Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
A first embodiment of the present invention relates to a cushion pad, which is provided in a housing 1 of a cleaner to separate a motor 2 of the cleaner from the housing 1 of the cleaner, as shown in fig. 1, 3 and 4. The shock pad includes shock-absorbing ring 3 and the flexible arch 4 of a plurality of, and the surface at motor 2 is established to 3 covers of shock-absorbing ring, and the flexible arch 4 of a plurality of encircles around the axis N direction of shock-absorbing ring 3 and establishes, all separates each other between two arbitrary adjacent flexible arch 4 and forms recess 5, and each flexible arch 4 at least part supports the internal surface of dust catcher casing 1. The damping ring 3 can be a rubber ring tightly sleeved on the outer surface of the motor 2 and is not easy to separate from the motor 2, and can also be a plastic ring which is clamped on the outer surface of the motor 2 and is not separated from the motor 2 when the motor 2 vibrates.
It is not difficult to find that, as the damping ring 3 and the plurality of flexible protrusions 4 are arranged, the damping ring 3 is sleeved on the outer surface of the motor 2, the damping ring 3 is connected with the motor 2, the flexible protrusions 4 are annularly arranged around the axis N direction of the damping ring 3, any two adjacent flexible protrusions 4 are mutually separated to form the groove 5, at least part of the flexible protrusions 4 are propped against the inner surface of the dust collector shell 1, the vibration generated by the motor 2 during the vibration of the motor 2 is transmitted to the damping ring 3, the flexible protrusions 4 can generate deformation after receiving the vibration, due to the existence of the grooves 5, enough deformation space is provided for the flexible protrusions 4, so that the flexible protrusions 4 are expanded to the grooves 5 at two sides when being influenced by the vibration generated by the motor 2, the vibration generated by the motor 2 is greatly reduced on the flexible protrusions 4, and the vibration really transmitted to the shell 1 is small, the vibration generated by the motor 2 is better absorbed. And only each flexible bulge 4 of the shock pad is propped against the inner surface of the shell 1, so that the contact area of the shock pad and the inner surface of the shell 1 is smaller, and the vibration transmitted to the shell 1 is further reduced. And then this shock pad is better to the shock attenuation effect of motor 2, the vibrations that also can be better absorption motor 2 produced prevent that motor 2 from shaking to transmit to dust catcher casing 1 on, improve user experience.
Further, as shown in fig. 2, both side groove walls of each groove 5 extend obliquely toward a direction away from each other from an end connected to the damper ring 3 to an end away from the damper ring 3. Therefore, the distance between two adjacent flexible protrusions 4 is large, and a large space is further generated to deform the flexible protrusions 4.
In addition, each flexible protrusion 4 is integrally formed with the shock absorption ring 3, and both the flexible protrusion 4 and the damping ring can be rubber members.
Alternatively, as shown in fig. 1 and 2, the two adjacent flexible protrusions 4 are spaced at the same distance, so that the flexible protrusions 4 can uniformly and virtually reduce the vibration generated by the motor 2, and the housing 1 of the vacuum cleaner does not receive strong vibration in any direction.
Further, as shown in fig. 1, 2 and 3, the damping ring 3 is further provided with a plurality of through holes 6, each through hole 6 is annularly arranged around the axis N direction of the damping ring 3, the axis N direction of each through hole 6 is the same as the axis N direction of the damping ring 3, and any one through hole 6 penetrates through the end surfaces of the two sides of the damping ring 3. Due to the through hole 6, when the vibration generated by the motor 2 is transmitted to the damping ring 3, the damping ring 3 deforms and extrudes into the through hole 6, so that the damping ring 3 has enough deformation space, and the vibration of the motor 2 can be weakened by the damping ring 3.
Preferably, as shown in fig. 2, a through hole 6 is formed in a center line P of any one of the flexible protrusions 4 extending toward the axis N of the damper ring 3, so that when the flexible protrusion 4 receives vibration generated by the motor 2, the flexible protrusion can deform toward the through hole 6 to release an acting force applied to the flexible protrusion 4.
It is more worth mentioning that, as shown in fig. 1 and 4, the cushion further includes a flexible positioning protrusion 7 disposed on the outer surface of the cushion ring 3, and the flexible positioning protrusion 7 is used for being fixed in the housing 1.
In addition, as shown in fig. 1 and 4, the flexible positioning projection 7 is matched with the inside of the housing 1 in shape, so that the shock-absorbing pad can be stably placed in the housing 1 of the dust collector. In this embodiment, the casing 1 of the vacuum cleaner is partially a plane, and one side of the flexible positioning protruding block 7 facing the casing 1 is also a plane, and is matched with the casing 1, and when the shock pad is placed in the casing 1, the plane of the flexible positioning protruding block 7 is abutted to the plane of the casing 1, so that the shock pad is placed in the casing 1 more stably, and the motor 2 is also placed in the casing 1 more stably.
A second embodiment of the present invention relates to a motor damping device of a cleaner. In a second embodiment of the present invention, as shown in fig. 5 and 6, the motor damping device includes at least one damping pad of the first embodiment, each damping pad is disposed in the housing 1 of the vacuum cleaner to separate the housing 1 and the motor 2 disposed in the housing 1 from each other, the damping ring 3 of each damping pad is sleeved on the outer surface of the motor 2, and the flexible protrusion 4 of each damping pad at least partially abuts against the inner surface of the housing 1. So that the motor 2 fixes the motor 2 within the housing 1.
In the present embodiment, two shock absorbing pads are provided as an example, the inner surface of the housing 1 includes a side surface 11 and a bottom surface 12, one of the shock absorbing pads is sleeved on the end of the motor 2, the end of the motor 2 is opposite to the bottom surface 12 of the housing 1, and the shock absorbing pads separate the end of the motor 2 from the bottom surface 12 of the housing 1. Another shock attenuation pad cover is established in motor 2 middle part, separates motor 2 and side 11 of casing 1 to motor 2 is stably fixed in casing 1, and each part of motor 2 also all separates with casing 1, and the vibrations that motor 2 produced can not directly transmit to casing 1.
In addition, the motor damping device can also be a damping cushion sleeve arranged on the outer surface of the motor 2.
A third embodiment of the present invention relates to a vacuum cleaner comprising a housing, a motor and the motor damping device of the second embodiment, the motor being disposed within the housing.
