Power transmission device for water jet type body massager {APPARATUS TRAVELING OF POWER FOR EJECTING WATER-TYPE FULL BODY MASSAGE MACHINE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power transmission device of a water jet type general body massager, which is used in a water jet type general body massager for reciprocating a high pressure water injection device in a bed to perform a display massage by high pressure water. The present invention relates to a power transmission device of a water jet type full-body massager, which manufactures a timing pulley and a top cover and a bottom cover that can transmit power to improve a product's assembly and productivity and completely prevent leakage at this stage.

In general, massage refers to a certain part of the body that is repeatedly pressed for a predetermined time or more, causing painful stimulation or shaking the body part somewhat, causing fatigue to relax rigid skin and muscles and improving blood circulation. It is an artificial action to improve and activate the effect, such as fatigue recovery and stress relief, muscle pain, obesity, disc, back pain, neuralgia, joint pain, joint stiffness, lethargy, lack of exercise, neurosis, insomnia, anxiety, blood circulation, It is widely known to be effective in promoting metabolism, stroke and various hemiplegia.

Conventionally, various types of massage apparatuses for such a massage are known, and a body massage apparatus that can massage the whole body by spraying water at a high pressure is also known.

The whole body massage device of the Republic of Korea Patent Publication No. 10-0253880 as a conventional massage device using the conventional water pressure is coated on the elastic sheet of natural rubber or soft synthetic rubber on the upper surface of the bed, and sprays the high pressure water inside the bed A rodless cylinder is installed in which the sprinkler is reciprocally installed to the side in the longitudinally inner side of the bed, and a chain is installed in the inner piston thereof so as to be able to be pulled into the sprinkler. Both ends of the lease cylinder are in communication with the water pipes via the solenoid valve so that the high pressure water generated by the water pump can be selectively supplied, and a radiator or an air conditioner is installed between the reservoir and the water pump. .

However, although the conventional body massage device utilizes a portion of the high pressure water generated in the water pump as energy consumed for the reciprocating motion of the sprinkler, the sprinkler is reciprocated by the water pressure of the water pump, and several solenoid valves are used. There is a problem that it is difficult to control the sprinkler operation precisely and smoothly by controlling the operation of the sprinkler forward, backward movement and stop.

And, the sprinkler is exposed on the base plate as a whole to run, because the distance between the elastic sheet and the base plate coupled to the upper end of the bed is entirely high, so that the sprinkler is sprayed from the sprinkler and the pressure falling on the elastic sheet after falling down There was a problem in that the falling noise is greatly generated, and the operation noise of the solenoid valve by the high pressure water is greatly generated.

In addition, the conventional full-body massage device is equipped with a separate radiator for cooling the water temperature to a proper temperature because the water temperature rises due to friction, etc. when the massage operation by the water spray of the sprinkler proceeds for a long time, but the weather like winter In the case of cold, the elastic sheet and the temperature of the water is low, so the initial operation of the device is not available, and after the idle time for a predetermined time can be massaged because there is a problem not only inconvenient to use, but wasted driving energy.

In addition, the conventional body massage device has a problem that the monitor is installed on one side of the bed can be massaged by the assistant to perform the operation, the patient himself can not perform a suitable massage.

The present inventors to reduce the operating noise and falling water noise of the device in consideration of the conventional problems as described above, to increase the injection pressure of the injector running in a submersible to thereby improve the massage effect, By preheating the water to the proper temperature and supplying it to the injection device, the patient can receive a comfortable massage from the beginning of operation. He was filed as a Korean Patent Application No. 2002-21695.

The water jet type full-body massager, which is elected in this way, is provided with a water tank inside the rectangular cylindrical body case provided with four main walls and a bottom plate, and a support net and an elastic sheet are coupled to the upper end of the body case so that the inner space is sealed.

Is installed submerged in the mobile channel, the injection device is driven by the timing belt and the pulley by the driving force of the motor, there is an advantage that the operating noise and falling noise of the device is significantly reduced, the upper part of the submersible injector Ejector-type injection nozzle is installed to increase the injection pressure there is an advantage that the massage effect is improved.

Furthermore, a pair of bearings are respectively coupled to the transmission element of the driving means by the semi-cylindrical upper and lower covers, each of which is fixed with overlapping openings, and a belt passing groove formed on both sides of the main wall, and a seating groove of the upper and lower covers. And, the timing pulley is condensed to the upper and lower bearings, and the packing is inserted into the sealing groove formed in the lower bearing seating groove of the lower cover, so it is assembled into a single piece, so that it can be easily installed in the product There is an advantage of improving assembly and productivity.

In addition, the packing is installed in the lower portion of the bearing of the lower cover, the motor is disposed outside the base, the drive shaft of the motor is coupled to the drive pulley of the electric element through the through hole formed in the tank, the packing is inserted into the groove formed in the base There is an advantage that can be completely prevented leaks at this stage.

In addition, the timing pulley is installed inside the upper and lower covers, and the timing belt passing grooves are formed in the main walls of the upper and lower covers to easily connect the timing belt and the pulleys, and are advantageous for constant speed operation. The high BLDC motor is assembled, and its configuration is simple, and it is very advantageous to employ it as a power transmission device used underwater because of its excellent constant speed operation, noise reduction, assemblability, and leakage blocking power.

The present invention as described above has the advantage that the patient can receive a high-quality massage in a more comfortable environment while using a water jet type massage device, and can improve the assembly productivity, durability, and reliability of the product.

Although the above description has been made with reference to a preferred embodiment of the present invention, those skilled in the art will variously modify and change the present invention without departing from the spirit and scope of the present invention as set forth in the claims below. I can understand that you can.
