Abstract

The utility model discloses an electric-massaging sofa, comprising a backrest, arm rests, a seat cushion, etc. A pounding device or a vibration device is arranged in the sofa. The pounding device is realized by that under the combined action of a spring and an eccentric pin driven by a small motor, a pounding rod pounds the inner wall of the sofa where the pounding rod is positioned at certain frequency, and the vibration device is realized by a small motor which is provided with an eccentric wheel. The utility model has certain massage and physical therapy action for the people who often feel discomfortable or aching pain and numb on the back position, waist position or leg position and has the advantages of simple device and small size. The utility model can be installed in any position in the sofa.

Description

Electric-massaging sofa

The utility model relates to the sofa in the furniture class, specifically a kind of electric massage sofa with physical therapy function.

Chinese patent 85201448 and 86205084 discloses a kind of tilting-type fluctuation couch, the undulator of being made up of extension spring, stage clip and interior overcoat etc. is housed between bearing and handrail, by the gravity center of human body change cause fluctuation be the elastic force undulator, be the power fluctuation device by motor through what lever, pull bar etc. drove, in addition can in adorn the massager of forming by electromagnet.

The utility model provides a kind of simple in structure, safe in utilization, by knocking to strengthen the new-type sofa of massaging and physiotherapeutical function.

The purpose of this utility model is achieved in that to be exactly device one cover or number cover knocking device or vibrating device in the backrest of various sofas or cushion.The knocking device is the knocking rod of straight or a broken line or an arc shape, one end is a caput, in wrap up in foamed plastics, the cloth that outsourcing is wear-resisting or other abrasion resistant fibrous fabrics, the other end is excellent tail, is connected with drive unit, between caput and excellent tail, a fulcrum is arranged, fulcrum is fixed on the support by activity by sliding sleeve, and fulcrum be a power arm to a section of excellent tail, and fulcrum is the arm of thumping to a section of caput.Drive unit is a small machine, adorn a driving wheel on its axle, same follower of this driving wheel is meshed, on the disk of follower, at least one cam pin of positioned vertical, when static, cam pin is being supported excellent tail, after the startup, cam pin drives power arm with passive crop rotation circular motion the time and moves, behind certain position, rod tail slippage cam pin, but under the effect of spring, excellent tail is fallen on the cam pin that rapid rotation comes once more, goes round and begins again, the circular motion of eccentric rod orders about power arm with certain warble, thereby make the also swing synchronously of knocking arm, caput reaches the relevant position of human body then and plays massage effect with constantly the thump inwall of sofa backrest or seat cushion of same frequency.Spring has multiple device mode, but has at least an end to be fixed on the power arm or knocking arm of knocking rod.After the rotating ratio of the rotating speed of small machine and driving wheel and follower was determined, the frequency of knocking mainly determined by the radical of cam pin, cam pin the more, frequency is higher.The strength of knocking is with the quality of beating head and the intensity positive correlation of spring.Vibrating device is a small machine, and its axle head is fixed an eccentric wheel, and behind the connection power supply, small machine just is in the unstable equilibrium operating condition, thereby produces vibration, and this vibration is passed to human body through the inwall of sofa backrest or seat cushion and played massage effect.For the protection small machine also conveniently is fixed on the sofa, can and be fastened in the plastic casing the small machine sealing, also can wrap outside it with foamed plastics.These two kinds of devices can be fixed on the interior a certain position of sofa as required, and these the two kinds used power supplys of device are 220 volts of alternating currents, and the safe voltage that becomes below 36 volts through transformer is added on the small machine, as using direct-flow small motor, also needs to add thereon after the rectification.It is controlled to be secondary; the first order is the power switch that is contained on the handrail; the second level is respectively to adorn a spring contact switch on the incoming line that leads to each small machine behind the transformer; after the people sits on the sofa, the spring contact switch connection, can select power switch this moment as required; device is started working after connecting power supply; the people leaves sofa, and the spring contact switch opens circuit, just autostop.

Advantage of the present utility model is that the function of thumping, vibrating does not often feel well to those backs, waist or shank even the numb people that aches can play certain massaging and physiotherapeutical effect, to remove people's pain, sets up as early as possible.Knocking and vibrating device are simple in structure in addition, and volume is little, can be contained on any one position of any sofa and select use for people.

Fig. 1 is for being equipped with knocking and vibrating device schematic diagram on backrest.

Fig. 2 is knocking apparatus structure schematic diagram.

Fig. 3 is the vibrating device structural representation.
