[0039] Embodiment 3 of the utility model of an electric lifting bed

[0040] Reference Figure 1-Figure 5As shown, a mounting seat 1008 is installed on the upper end surface of the base frame 1001 near the bottom end of the worm gear 3005, and a worm 1002 is rotatably connected inside the mounting seat 1008, and the worm 1002 and the worm gear 3005 are meshed with each other. A reducer 1006 is installed on one side of the mounting seat 1008 at the upper end of the base frame 1001, and a servo motor 1007 is installed on one side of the reducer 1006. The output end of the servo motor 1007 is transmission-connected to the input end of the reducer 1006, and the output end of the reducer 1006 is transmission-connected to the worm 1002. A telescopic plate 1005 is installed on the inner top of the slide 1004, and the bottom end of the telescopic plate 1005 is fixedly connected to the bed board 2001. A touch panel is installed on one side of the bed frame 1003, and the touch panel The input and output ends are communicated with the input and output ends of the servo motor 1007, the heating coil 4002 and the fan 2004. By meshing the worm wheel 3005 with the worm 1002, when the worm 1002 rotates, the bidirectional screw 3002 can be driven to rotate. By installing the servo motor 1007 and the reducer 1006, the transmission effect of the servo motor 1007 can be improved, thereby driving the worm 1002 to rotate, so that the bed board 2001 can be raised and lowered.

By installing the touch panel, the user can conveniently control the opening and closing of the servo motor 1007, the heating coil 4002 and the fan 2004.

[0041] Specifically, the working principle of this electric lifting bed is as follows: when in use, the user can start the servo motor 1007 through the touch panel, so that when it works, the worm 1002 is driven to rotate through the reducer 1006, and the worm 1002 is meshed with the worm wheel 3005 sleeved on one end of the bidirectional screw 3002, so that the bidirectional screw 3002 is rotated, and the wedge block 3003 threadedly connected at both ends of the bidirectional screw 3002 is slidably connected to the slide bar 3001.

By installing a plurality of fans 2004 at the bottom end of the bed board 2001, when the fans 2004 are working, air can be blown into the interior of the bed board 2001 and blown to the patient's back through the air grooves 2002, thereby improving the heat dissipation and ventilation effect of the contact part between the patient and the bed board 2001. By arranging a heating coil 4002 inside the breathable non-woven bag 4001, when the patient needs to keep warm, the heating coil 4002 can be turned on, and at this time, the fan 2004 blows the gas inside the bed board 2001, and generates hot air that blows toward the patient after heating.

[0042] It should be noted that in an electric lifting bed, the specific models and specifications of the touch panel, servo motor 1007, heating coil 4002 and fan 2004 need to be selected and determined according to the actual specifications of the device.
