Description
Technical field
The utility model relates to water purifier field, has particularly related to a kind of water purifier with damping noise-decreasing device.
Background technology
Water pump in water purifier and motor, it is the place that noise the most easily occurs to shake and produce, motor shock absorption mode of the prior art, as shown in Figure 1, that cushion blocking is set by the motor underfooting at motor, by bolt and nut, motor pin, cushion blocking are fixedly connected with motor base, wherein screw rod has run through whole cushion blocking, the screw rod of rigidity has very strong conductivity to vibrations and noise, can by the vibration of motor and noise to motor base and exterior conductive, cause that whole equipment noise is large, vibration is large, sometimes also can cause the generation of resonating.
Summary of the invention
The utility model, for above-mentioned shortcoming, provides a kind of water purifier with damping noise-decreasing device.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
With the water purifier of damping noise-decreasing device, motor is connected with base by damping noise-decreasing device, and damping noise-decreasing device comprises closing waist cylinder and 2 screw rods, and 2 screw rods are separately fixed at the upper and lower two ends of closing waist cylinder.Screw rod is embedded in closing waist cylinder in advance by Shooting Technique.Be not rigidly connected between the screw rod of closing waist cylinder upper end and the screw rod of lower end, can prevent from passing to motor base between the vibration of motor.Closing waist cylinder is made up of soft material, and when its axially loaded, the middle part of closing waist cylinder deformation can occur, and can reduce the transmission of motor oscillating to greatest extent.
As preferably, closing waist cylinder is flexible PVC closing waist cylinder.Flexible PVC is the PVC material that with the addition of softening agent.
As preferably, the outer contour of closing waist cylinder vertical cross-section comprises revolver profile and right skeletal lines, and revolver profile and right skeletal lines are circular arc line, and revolver profile and right skeletal lines are about the axisymmetrical of closing waist cylinder.
As preferably, the outer contour of closing waist cylinder vertical cross-section comprises revolver profile and right skeletal lines, and revolver profile and right skeletal lines are about the axisymmetrical of closing waist cylinder, and revolver profile and right skeletal lines form hyperbolic line.
As preferably, using the intersection point of the vertical axis of symmetry of closing waist cylinder vertical cross-section and horizontal symmetry axis as the center of circle, using horizontal symmetry axis as x-axis, the hyperbolic function at hyperbolic line place is x
2-y
2=k, wherein k is constant.
As preferably.k＝1。
As preferably, screw rod is also provided with nut.
The utility model mainly carries out noise reduction from two aspects to water purifier and achieves obvious effect: the connection of first motor and motor base is changed into by Hard link and being flexible coupling, and the vibrations of motor are reduced, and reduces vibration and noise from sound source; It two is by the improvement to web member hardness, the vibration of being transmitted by web member is reduced, and by testing and repairing positive k value, avoids the generation of resonance phenomenon.The utility model, owing to have employed above technical scheme, can reduce noise that water purifier runs and weaken the vibration of water purifier.

Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
Embodiment 1
With the water purifier of damping noise-decreasing device, as shown in Figure 3, comprise closing waist cylinder 4, the material of closing waist cylinder 4 is flexible PVC, and wherein plasticizer loading is 40%.The material of softening agent is that aliphatics completes vinegar.Closing waist cylinder about 4 two ends are all fixed with screw rod 3.Screw rod 3 is also provided with nut 5.
Water purifier with damping noise-decreasing device is placed on the below of the motor pin of motor 1, and as shown in Figure 2, the screw rod 3 of closing waist cylinder 4 upper end is tightened with nut 5 through after motor pin, and the screw rod 3 of closing waist cylinder 4 lower end is also tightened with nut 5 through after base 2.
The outer contour of closing waist cylinder 4 vertical cross-section comprises revolver profile 401 and right skeletal lines 402, and revolver profile 401 and the axisymmetrical of right skeletal lines 402 about closing waist cylinder 4, revolver profile 401 and right skeletal lines 402 form hyperbolic line.Using the intersection point of the vertical axis of symmetry of closing waist cylinder 4 vertical cross-section and horizontal symmetry axis as the center of circle, using horizontal symmetry axis as x-axis, the hyperbolic function at hyperbolic line place is x
2-y
2=1, x < 30cm.
The relation with contents of applicant to the elongation of flexible PVC, tensile strength, shore hardness and softening agent is all tested.For the ease of test, as Fig. 4, the PVC material set here except softening agent is total up to 100 parts, plasticizer consumption unit be part, corresponding 54 parts ~ 100 parts (54 ÷ 154=35%, the 100 ÷ 200=50%) of percentage ratio 35% ~ 50% in claim.From Fig. 4 and Fig. 5, along with the increase of plasticizer consumption, hardness, tensile strength are in decline, and elongation is in rising, and compression set is in reduction.It is that be easy to be seeped between PVC macromolecular chain, physical entanglement point reduces relatively, causes molecular force to weaken because softening agent is low-molecular material that tensile strength declines, and macro manifestations is that tensile strength reduces.
In a word, the foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
