Each set of strip-shaped wall grooves 14 is slidably connected to a triangular cavity sleeve 51 in the vertical direction. A bottom pad 53 is fixedly installed at the bottom corner of the bed body 1. A support spring 52 is fixedly connected between the triangular cavity sleeve 51 and the bottom pad 53. A hollow bracket 5 is fixedly connected between the multiple triangular cavity sleeves 51. Through the above structure, the cooperation between the triangular cavity sleeve 51 and the strip-shaped wall grooves 14 can strengthen the bed body 1 and improve the structural stability at the corners of the bed body 1.

[0045] As a further scheme of the present application, the gas delivery unit comprises a gas cavity 44 opened on the headrest 4, and the gas cavity 44 is in communication with the ventilation channel 43, a plurality of branch openings 45 are evenly distributed and opened on the position of the headrest 4 close to the gas cavity 44, and the plurality of branch openings 45 are in communication with the gas cavity 44, and the branch opening 45 is in S-shaped structure; by using the branch opening 45 in S-shaped structure, the air can be buffered to a certain extent, so that the air is discharged at a more gentle rate, avoiding the direct blowing to the personnel.

[0048] Through the above structure, when the slide column 73 moves, the push-pull plate 81 can be driven to move synchronously, and when a person gets on the bed, the hollow bracket 5 moves downward under the weight, and by the conduction of the piston rod 71 and the slide column 73, the push-pull plate 81 is pushed to move, so that the air in the bellows 8 can be discharged into the ventilation channel 43 through the exhaust pipe 84, and then the air is uniformly discharged to the vicinity of the personnel through the gas cavity 44 and the branch opening 45.

[0052] Through the above structure, the auxiliary end cylinder 6, the piston supporting rod 62, and the reset spring two 63 cooperate with each other to assist in supporting the hollow bracket 5. When the hollow bracket 5 moves downward, the piston supporting rod 62 moves downward synchronously, and the air in the auxiliary end cylinder 6 is discharged through the plurality of conical head air pipes 61, thereby effectively enhancing the air flow below the mesh carbon plate 3, and effectively avoiding the heavy humidity condition of the bed body after long-term use.

[0053] As a further scheme of the present application, a strip-shaped sliding groove 12 is formed on each side of the bed body 1, and a base baffle 2 is slidingly connected in the two strip-shaped sliding grooves 12, a sleeve plate 22 is slidingly sleeved on the base baffle 2, and a bristle end 26 is arranged on the bottom side wall of the sleeve plate 22.

[0054] Further, a sink groove 21 is formed on each side of the top end of the base baffle 2, an extension flap 23 is fixedly installed on each end of the top of the sleeve plate 22, and the extension flap 23 is slidingly connected to the sink groove 21, a vibration spring 24 is fixedly installed between the extension flap 23 and the sink groove 21, and a ball head rod 25 is fixedly installed on each end of the sleeve plate 22.

[0055] Further, a set of limiting stop columns 11 are fixedly arranged on the surface of the bed body 1, and the limiting stop columns 11 are in a cylindrical structure, and the two sets of limiting stop columns 11 are staggered.

[0056] Through the above structure, the base baffle 2 is moved to one end of the bed body 1, and the base baffle 2 cooperates with the plurality of limiting stop columns 11 to effectively limit the laid bedding, thereby increasing the use experience of the spring bed.

[0057] When the bed body 1 needs to be cleaned subsequently, the laid bedding can be removed, and the base baffle 2 is pushed to move along the strip-shaped sliding groove 12, the ball head rod 25 on the sleeve plate 22 can abut against the limiting stop column 11, and the vibration spring 24 cooperates to make the sleeve plate 22 reciprocate along the base baffle 2, thereby greatly improving the cleaning effect of the bristle end 26 on the mesh carbon plate 3.

[0058] The specific working method is: in use, the bedding is laid on the mesh carbon plate 3 of the bed body 1, the base baffle 2 is pushed to one end of the bed body 1, and the base baffle 2 cooperates with the plurality of limiting stop columns 11 to effectively limit the laid bedding; when the bed body 1 needs to be cleaned subsequently, the laid bedding can be taken away, and the base baffle 2 is pushed to move along the strip-shaped sliding groove 12, the ball head rod 25 on the cover plate 22 abuts against the limiting stop column 11, the vibration spring 24 is arranged in cooperation, the cover plate 22 reciprocates along the base baffle 2, so that the cleaning effect of the brush end 26 on the mesh carbon plate 3 is greatly improved, the mesh carbon plate 3 adsorbs odors, and the air in the bed body 1 area is purified;
