It is possible to provide the cushion device of the solenoid for massage that can be supplied at low cost because the effect can be doubled and the structure is simple and there is no breakdown and the production cost is low.

Description

Cushion device of massage solenoid. {An cushion equipment of massages soldenoid}

The present invention provides a solenoid by installing a bobbin, a moving core, a guide part, a support hole, a spring, a striking part, etc. in the fixed cover, while simultaneously restraining the noise generated when the moving core of the solenoid moves forward and backward. A cushion solenoid for a massage solenoid, characterized in that the operation of the striking portion is performed smoothly.

As is well known, a massage chair, a portable massager, and the like are installed in various massage means, so that the magnetic field of the bobbin installed in the fixed cover is installed in the core part of the magnetic coil in order to achieve the massage effect by advancing the striking part. When the moving core of the length is penetrated and the current flows through the magnetic field coil, the moving core overcomes the force of the spring and repeatedly moves back and forth to achieve the desired massage effect.

Looking at the conventional solenoid that is applied to the massager as a retraction operation means as described above is installed through the core portion of the magnetic coil to move the bottom of the movable core to the bottom of the movable core to limit the retreat range of the movable core, movable iron core The upper side of the movable core was equipped with a support, spring, and striking part.

Therefore, it responds flexibly to the falling force applied to the moving core on the coil spring and prevents it from excessively rising. However, as the fixed cover base of the solenoid and the bottom of the moving core come into contact with each other, a lot of noise is generated as well as the moving core. Coil springs installed on the outer edge of the exposed part also have many problems because the operation noise is generated by repeated contraction and restoration, resulting in discomfort caused by the operation noise during use.

In order to solve the conventional problems as described above, the bobbin is installed in the fixed cover, and the upper and lower plates of the fixed cover coincide with the core of the bobbin to allow the movable core to penetrate through the upper and lower plates. The perforated hole of the cushion plate is matched, and the perforated hole of the upper and lower cushion is protruded up and down.The corrugated protrusion of the upper cushion plate is the bottom of the base and the bottom of the movable core It is intended to allow the user to get the maximum massage effect with a pleasant atmosphere during operation by suppressing friction noise as much as possible during the movement of the moving iron core.

This will be described in detail based on the accompanying drawings.

With a plan view

The bobbin 2 is provided between the upper plate 7 and the bottom plate 8 of the fixing cover 1, and the through hole 9 of the top plate 7 and the bottom plate 8 is connected to the core portion 16 of the bobbin 2. The guide portion 12 is inserted so that the upper limit of the movable iron core 11 is controlled and the accurate movement of the retracted operation is performed on the upper side of the core portion 16. In the upper portion of the movable iron core 11 protruding to the outside of the bobbin (2) in the order of the support port 13, the coil spring 14, the striking portion 15 in order to form a solenoid (S), 7) the upper and lower cushion rubber plates (4) and (4a) are inserted between the base plate (13), the base plate (8) and the bottom surface (10) of the movable iron core (11), respectively. The corrugated protrusions 3 protruding around the through holes 5 and 5a protrude in the vertical direction.

In the figure, reference numeral 6 is a fixing hole of the upper plate 7 and the bottom plate 8,

In the assembly method of the present invention configured as described above, the bobbin 2 and the movable core 11 are installed between the upper plate 7 and the bottom plate 8 of the fixed cover 1 as in the general solenoid S, but the upper plate 7 Insert the upper and lower cushioning rubber plates (4) and (4a) between the upper surface and the bottom of the base (13) and between the bottom plate (8) and the bottom surface (10) of the movable iron core (11), but penetrate the upper and lower cushioning rubber plates (4) and (4a). As the corrugated protrusions 3 protruding from the periphery of the balls 5 and 5a are protruded in the up and down direction, the movable iron core 11 moves when the core portion 16 of the bobbin 2 moves forward and backward. Corrugated projections (3) that generate noise when the bottom surface (10) of the iron core (11) and the bottom of the bottom plate (8) of the fixing cover (1) and the bottom surface of the support opening 13 and the top surface of the top plate (7) Is characterized in that can be sequentially absorbed by the noise.

In particular, the corrugated protrusions 3 protruding around the through-holes 5 and 5a of the upper and lower cushion rubber plates 4 and 4a of the present invention are divided into four equal parts and become wavy, and thus bobbins (2). When the movable core 11 is moved in and out of the core portion 16) of the core part 16, it is buffered in two or three times by the corrugated protrusion 3, so that the massage effect of the hitting hole 15 during massage is smooth. Noise-free noiseless operation allows the user to operate with a refreshing mood.

As described above, the present invention provides a multi-stage buffering effect due to the corrugated protrusions protruding from the periphery of the through hole of the upper and lower cushions when operating the solenoid. The effect can be doubled and the structure is simple, so there is no breakdown and the manufacturing cost is low.
