Abstract

The utility model provides a double quality vibration device for a massage. A magnet is considered as a center. The upper end and the lower end of the magnet are respectively connected with an outer case through springs. A group of coils is respectively arranged in the upper half part and the lower half part of the magnet. The bottom of the outer case is connected with springs in beds or sofa beds. After the alternating current is switched on, the coils produce an AC magnetic field which is either the same or opposite to the polarity of the magnet from time to time. Thus, the magnet moves either upwards or downwards from time to time. Because the outer case is connected with the springs, the utility model follows upwards and downwards. Thus, the massage is implemented for the person lying in bed or the person sitting in sofa bed. The utility model has no spark, no noise and long service life and is suitable for use in spring beds, sofa beds, etc.

Description

Double quality vibration device for massage

This utility model belongs to a kind of vibrator, particularly is used for two quality vibrators of massaging.

The Simmons bed and the sofa of extensive use at present are the plank bed that in the past used and the modified model of plate chair, and purpose is to provide comfortable, a softish rest, sleep environment to people.But to old people, athlete or the bigger physical labourer of some labor intensity, when they lie up or are sitting in the sofa, need massage, so that alleviating pain and degree of fatigue quicken sleeping.Obviously, this Simmons bed and sofa are difficult to meet the demands.

In order to address this problem, China applies for a patent CN90210178.1 a kind of massage Simmons bed and Massage sofa is provided, its technical essential is: in the groups of springs in Simmons bed and sofa, after the vibrator energising is installed, vibrator just along with the vibration of the perpendicular direction of the contact surface of bed surface or sofa, bed or the people that sits sofa are produced massage effect.Formed on the driving shaft of direct current generator but the vibrator that this massage couch or Massage sofa are selected for use is connected in by eccentric, therefore, the problem that this vibrator exists when work is: (1) easily produces electric spark; (2) noise is bigger; (3) life-span is shorter.

This utility model purpose just is to provide a kind of can avoid the two quality vibrators of above-mentioned insufficient massage.

Below in conjunction with description of drawings this utility model is how to realize its purpose:

Fig. 1 is a longitudinal sectional view of the present utility model.

The utility model is centered by cylindrical permanent magnet 5, the magnet lower end is placed on the base 7 by pressuring spring 8, and the upper end of magnet is connected on the loam cake 1 by spring 2, in the first half and the Lower Half of magnet one group of coil 3 is arranged respectively, be magnetic guiding loop 4 in the outer ring of coil, connect together with shell 6. The utility model is placed in the groups of springs in sofa or the Simmons bed, and it accounts for the position of a spring, and its base links to each other with adjacent four springs.

Operation principle is: after giving the coil indirect current, in coil, produce alternation magnetic field boundary, identical with the polarity chron of permanent magnet, the time and opposite, so the time and repel each other, the time and inhale mutually , so that permanent magnet moves upward when alternating current is positive half cycle, during negative half period, move downward. Because base of the present utility model is to be connected on the spring, so the moving up and down of magnet, by being connected in magnet spring 2 and 8 up and down, drive the utility model also and then the time at present, therefore when the people lies in bed or be sitting on the sofa rest, the people is produced massage effect.

This utility model compared with prior art has the following advantages:

1, no-spark;

2, noiselessness;

3, the life-span is long.

Claims

1, the two quality vibrators of a kind of massage, it is characterized in that: it is to be the center with the cylindrical permanent magnet, pressuring spring is passed through in the lower end of Magnet, be placed on the base, the upper end of Magnet is connected in by spring and covers, the first half and Lower Half at Magnet respectively have one group of coil, are magnetic guiding loops in the outer ring of coil, connect together with shell.
