The working principle of the basic scheme is as follows: firstly, the sliding cover seals the storage chamber and is matched with the bed body, and the bed body is embedded on the wall body. When the bed body is needed, the control switch is pressed, the second electromagnet is electrified, the forward and reverse rotating motor starts to work, the second electromagnet generates magnetic force repelling with the second magnetic object after being electrified, the magnetic force can overcome the elastic force of the elastic support to do work, so that the sliding cover is pushed to slide towards the direction far away from the bed body, and the storage chamber is opened in the sliding process. The positive and negative rotation motor works to drive the rotating shaft to rotate forwards, when the sliding cover slides out for a certain distance, the height of the bed body is reduced, and at the moment, the rotating shaft rotates forwards to drive the bed body and the storage chamber embedded in the wall body to rotate downwards along the hinged position of the bed body and the storage chamber and the sofa seat; when the rotating shaft rotates forwards, the cam connected with the rotating shaft rotates along with the rotating shaft, the cam enables the connecting rod abutted against the rotating shaft to perform reciprocating linear movement in the rotating process, the connecting rod reciprocates to drive the piston connected with the connecting rod to reciprocate in the cavity, the piston reciprocates in the cavity to intermittently extrude the air bag, the air bag is extruded and then injects air into the storage chamber communicated with the air bag, and the injected air can remove dust in the opened storage chamber to clean the storage chamber; when the bed body and the storage chamber rotate downwards to a certain moment, the repulsive force of the second electromagnet to the second magnetic object is reduced to be insufficient to overcome the elasticity of the elastic support, the elastic support pulls the sliding cover to move and reset towards the direction close to the bed body, and the sliding cover closes the storage chamber again after resetting and is matched with the bed body, so that articles in the storage chamber are prevented from falling off when the storage chamber rotates downwards along with the bed body. When the bed body rotates to be parallel to the surface of the sofa seat, namely, the bed body is in a horizontal state, the proximity switch detects the storage chamber and immediately sends a control signal to control the forward and reverse rotating motor to stop working, the rotating shaft stops rotating after the forward and reverse rotating motor stops working, the bed body is automatically put down, and after the bed body is put down, the length of the storage chamber is adjusted to enable the storage chamber to be abutted against the ground, so that the bed body can be supported; when the bed body needs to be folded for use, the control switch is pressed again, the second electromagnet is powered off, the forward and reverse rotating motor starts to work again and drives the rotating shaft to rotate reversely, and the rotating shaft rotates reversely to drive the bed body in a horizontal state to rotate upwards along the hinged position of the bed body and the sofa seat; when the bed body rotates upwards to contact with a wall body, the sliding cover extruding the bed body moves towards the direction far away from the bed body again, so that the storage chamber is opened, after the storage chamber is opened, the rotating shaft rotates reversely to drive the cam to rotate, the cam rotates to drive the piston to reciprocate through the connecting rod abutting against the cam, the air bag is extruded by the piston intermittently again, and the air bag is extruded and then blows air out of the storage chamber again, so that dust in the storage chamber is blown out of the storage chamber again, and the storage chamber is cleaned again; when the bed body rotates to be embedded into the wall body again, namely the bed body is in a vertical state, the sliding cover is not extruded any more, the elastic support drives the sliding cover to reset again, so that the storage chamber is closed, the control mechanism receives a detection signal that the bed body is vertical and immediately sends a control signal to control the forward and reverse motor to stop working again, the rotating shaft stops rotating after the forward and reverse motor stops working, and the bed body is lifted automatically. When the bed body is in a vertical state, the control mechanism can send a control signal to control the first electromagnet to conduct electricity after receiving the detection signal, magnetic force is generated after the first electromagnet conducts electricity, and the generated magnetic force attracts a first magnetic object arranged on the bed body, so that the bed body is firmly attracted to a wall body after being lifted, and the bed body is prevented from suddenly falling to damage a sofa seat or injure a person; when the bed body is needed, the control switch is pressed down, the control switch can also control the first electromagnet to be powered off, the magnetic force for attracting the first magnetic substance on the bed body is lost after the first electromagnet is powered off, at the moment, the bed body is not firmly attracted on the wall body any more, and the bed body can be put down from the wall body by the forward rotation of the rotating shaft.

The beneficial effect of this basic scheme lies in: the bed body is automatically lifted and put down, the space utilization rate of a room is greatly improved, manual operation is not needed, manpower is saved, and the use is convenient; according to the scheme, the length-adjustable storage chamber is arranged at the tail of the bed body, so that articles can be stored, such as a bookshelf for placing books, and the bed body can be supported when the bed body is in a horizontal state; this scheme can also realize the self-cleaning to the storing room in the lifting with put down the bed body, has alleviateed the clean burden of later stage to storing space, labour saving and time saving.

Further, the control mechanism is a light-operated switch, and the light-operated switch is arranged on a wall body which can be in contact with the bed body.
