the first small belt wheel 29 and the second small belt wheel 30 are coaxial with the second straight gear 21 and the fourth straight gear 23 respectively, the first small belt wheel 29 and the second straight gear 21 are connected with the first large belt wheel 16 and the second straight gear 21 through the synchronous belt 19, the first large belt wheel 16 and the second large belt wheel 17 are connected with the fifth straight gear 24 and the sixth straight gear 25 on the chair back plate 11 through the belt wheel shaft 18 respectively, the fifth straight gear 24 and the sixth straight gear 25 are fixed on the chair back plate 11 and are respectively meshed with the two symmetrical rubbing back plates 14, the left rubbing back plate 14 is positioned by the guide grooves 12 fixed at the upper left corner and the lower left corner of the chair back plate 11, the right rubbing back plate 14 is also arranged, four universal balls 7 in contact with the chair back plate 11 are fixed on the inner sides of four azimuth angles of the rubbing back plate 14 respectively, and the bath brush 37 is fixed on the rubbing back plate 14 through four suckers;

the motor 31 below the chair bottom plate 8, the belt wheel and the gear transmission mechanism at the rear side of the chair back plate 11 are covered by the waterproof cover 6;

the electric push rod 32 is fixed in the middle of a beam between the two front chair legs through a matched support and a screw, and the electric push rod 32 is connected with the support through a pin 13;

the lower ends of two L-shaped connecting rods 34 symmetrically distributed below a chair bottom plate 8 are connected together through a U-shaped plate 36 through screws, holes are formed in the corners of the L-shaped connecting rods 34 and are assembled at two ends of a rotating shaft fixed on the chair bottom plate 8 and can rotate through the rotating shaft, the upper ends of the L-shaped connecting rods 34 are provided with vertical grooves and transverse through holes and are connected to extension holes at the lower end of a cushion 10 through pins 13, the front end of the cushion 10 is connected to the chair bottom plate 8 through three hinges 9 which are distributed equidistantly and can rotate around the front end of the chair to lift a fifteen-degree slope;

handrail 1 is fixed in 8 both sides of chair bottom plate, is provided with three circular button on 1 inboard some button panels 4 of the left side handrail of just going to the back of the chair, is provided with the warning light on handrail 1, and 1 inboard of handrail is equipped with the timer, and the 1 outside of left handrail is furnished with the gondola water faucet seat.

In a specific using process, when the bathing chair is used for bathing, if the bathing chair is used for bathing, a power cord at the back of the bathing chair is plugged into a power socket before bathing, and the chair is in a ready-to-work state after a prompting lamp on the left armrest of the chair is turned on. At the moment, the shower head can be inserted into the shower head seat of the chair, the article basket is fixed on the armrest, then bathing articles such as shampoo and the like are placed in the basket, and bathing can be started after the reminding time is set.

When the back rubbing step is carried out, the back rubbing button on the left handrail is pressed, the motor starts to rotate, the back rubbing plate on the chair back and the central supporting shaft are driven to rotate, and the back rubbing plate and the loofah sponge bath towel on the shaft play a role in back rubbing. Since gear three only serves to change direction, the two plates turn in opposite directions but at the same rate; when the two back rubbing plates rotate to the two sides of the chair back, the central supporting shaft can play a supporting role to prevent the old from falling backwards, and can play a role in supplementing back rubbing, and the two back rubbing plates can be rotated to rub the ridge grooves which can not be rubbed by the back rubbing plates. When the back rubbing board starts to move, the electric push rod cannot be started, and the start-up switch cannot be pressed at the moment. When the back rubbing is finished, the back rubbing button is pressed again, the motor stops rotating, and the back rubbing function stops.

When the old people finish bathing and prepare to get up, the lifting-assisting button is pressed, the electric push rod slowly extends, the L-shaped connecting rod rotates around the fixed rotating shaft through the U-shaped plate, the cushion is jacked up to slowly rotate around the front end of the chair through the hinge, and finally the optimal lifting-assisting gradient is achieved when the push rod reaches the maximum pushing range, so that the lifting-assisting function is completed. The old can more conveniently stand up by utilizing the pushing force of the cushion. For safety reasons, the back rubbing button cannot be pressed at this time.

The old man leads to cerebral circulation inefficiency very easily because of the time of bathing overlength when bathing, and symptoms such as coma, shock appear even, so this product provides time and reminds the function. The old man can preset time before bathing, can manually close after bathing, or automatic stop promptly when the power cuts off. After the time countdown is finished, the loud bell rings to give an alarm.

While the utility model has been described above with reference to an embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the utility model. In particular, the various features of the disclosed embodiments of the utility model may be used in any combination, provided that no structural conflict exists, and the combinations are not exhaustively described in this specification merely for the sake of brevity and resource conservation. Therefore, it is intended that the utility model not be limited to the particular embodiments disclosed, but that the utility model will include all embodiments falling within the scope of the appended claims.
