Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 The utility model provides a technical solution: a nursing chair, comprising a seat 1 and a chair back 2, a sponge cushion 21 is installed on the upper surface of the seat 1, and the sponge cushion 21 is provided to improve the comfort of the user sitting on the seat 1, and mounting grooves 13 are opened on the outer walls of both sides of the seat 1, and second electric telescopic rods 14 are installed inside the two mounting grooves 13, and the telescopic ends of the two second electric telescopic rods 14 are connected to a fixed seat 15, and an armrest 16 is installed on the upper surface of the fixed seat 15, and a controller 23 is installed on the upper surface of the armrest 16. The controller 23 is controlled to open, and the two second electric telescopic rods 14 are extended outward, thereby driving the two fixed seats 15 to move outward at the same time, so that the armrests 16 also extend outward, and the two second electric telescopic rods 14 are closed after reaching a suitable width, so that the distance between the two armrests 16 and the seat 1 can be adjusted according to users of different body shapes and widths, so that they will not feel crowded and restrained when sitting on the seat 1, and the comfort of the seat when in use is further improved.

[0022] A receiving groove 3 is provided on the chair back 2, and moving grooves 4 are provided on the inner walls of both sides of the receiving groove 3. A screw rod 5 is rotatably connected inside the left moving groove 4, and a moving block 6 is threadedly connected to the screw rod 5. A slide rod 7 is installed in the right moving groove 4, and the moving block 6 is slidably connected to the slide rod 7. Three connecting rods 8 are welded on the front of the moving block 6, and a massage block 9 is fixedly connected to the other end of the three connecting rods 8. A number of massage beans 10 are installed on the massage block 9. A motor 22 is installed on the back of the chair back 2, and the output end of the motor 22 is fixedly connected to one end of the screw rod 5. It is controlled by a controller 23, and the motor 22 is turned on to drive the screw rod 5 to rotate forward and then reverse, thereby driving the moving block 6 and the massage block 9 to move forward and backward under the limit guide of the slide rod 7, so that a number of massage beans 10 can move forward and backward, thereby massaging the user's back, thereby improving the user's comfort when using it.

[0023] A first electric telescopic rod 11 is installed on the front of the chair back 2, and a latex support block 12 is fixedly connected to the telescopic end of the first electric telescopic rod 11. When the controller 23 is turned on, the first electric telescopic rod 11 extends outward, thereby driving the latex support block 12 to extend outward until the latex support block 12 abuts against the user's back. The latex support block 12 supports the user's back, reduces the pressure on the user's waist, and thereby improves the user's comfort.

[0024] Five groups of third electric telescopic rods 17 are installed on the lower surface of the seat 1, and the telescopic ends of the five groups of third electric telescopic rods 17 are fixedly connected to the supporting base plate 18. The first electric telescopic rod 11, the second electric telescopic rod 14, the third electric telescopic rod 17 and the motor 22 are electrically connected to the controller 23. The five groups of third electric telescopic rods 17 are controlled to be turned on by the controller 23, and extend outward or retract inward to drive the seat 1 to move upward or downward. After reaching the appropriate position, the five groups of third electric telescopic rods 17 are closed, thereby realizing the effect of automatic adjustment of the seat height, facilitating use by users of different heights, and improving the practicality of the seat.

[0025] Two support seats 19 are welded to the lower surface of the support base plate 18. Anti-slip grooves are provided on the lower surfaces of the two support seats 19. A stabilizing rod 20 is fixedly connected between the two support seats 19. By setting two support seats 19, anti-slip grooves and stabilizing rod 20, the stability of the seat is increased during use.

[0026] Working principle: When in use, the controller 23 is controlled to open, and the five groups of third electric telescopic rods 17 extend outward or retract inward, driving the seat 1 to move upward or downward. After reaching the appropriate position, the five groups of third electric telescopic rods 17 are closed, realizing the effect of automatic adjustment of the seat height, which is convenient for users of different heights to use, improves the practicality of the seat, allows users to sit on the seat 1, and improves the comfort of users sitting on the seat 1 by setting the sponge cushion 21. The controller 23 is controlled to open, and the two second electric telescopic rods 14 are extended outward, thereby driving the two fixed seats 15 to move outward at the same time, so that the armrests 16 also extend outward. After reaching the appropriate width, the two second electric telescopic rods 14 are closed, so that the two armrests can be adjusted according to users of different body shapes and widths. The distance between the hand 16 and the seat 1 can be adjusted so that the user will not feel crowded or restrained when sitting on the seat 1, thereby further improving the comfort of the seat when in use. The controller 23 is controlled to turn on, and the first electric telescopic rod 11 extends outward, thereby driving the latex support block 12 to extend outward until the latex support block 12 abuts against the user's back. The latex support block 12 supports the user's back and reduces the pressure on the user's waist, thereby improving the user's comfort. The controller 23 is controlled to turn on the motor 22 to drive the screw rod 5 to rotate forward and then reverse, thereby driving the moving block 6 and the massage block 9 to move back and forth under the limit guide of the slide rod 7, so that several massage beans 10 can move back and forth, thereby massaging the user's back, thereby improving the user's comfort when in use.
