[0061] In some specific embodiments of this utility model, it further includes: a first pipe, a second pipe, a third pipe, and a three-way valve. The first pipe connects the three-way valve to the first air cushion 310, the second pipe connects the three-way valve to the second air cushion 320, and the third pipe connects the three-way valve to the air source. The three-way valve has a first state and a second state. The three-way valve is configured to: in the first state, connect the air source to the first air cushion 310; and in the second state, connect the air source to the second air cushion 320.

[0062] In this embodiment, by adjusting the three-way valve, the first air cushion 310 or the second air cushion 320 can be connected to save pipe length and space, while avoiding pipe tangling. The three-way valve can also have a third state, in which the air source is connected to both the first air cushion 310 and the second air cushion 320 to improve inflation efficiency.

[0063] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 As shown, in some specific embodiments of this utility model, the head support 200 is detachably connected to the bed frame 100; or, the head support 200 is integrated with the bed frame 100.

[0064] In this embodiment, the support head 200 can be manufactured separately and detachably connected to the bed frame 100, facilitating the improvement of the existing bed frame 100 without the need for a custom bed, thus reducing modification costs. The support head 200 can be bolted to the bed frame 100, or clamped and fixed to the bed frame 100. Specifically, the support head 200 includes a base plate 220, a side wall 230 connected to the base plate 220, and a connecting plate 240 connected to the side wall 230. The connecting plate 240 has a through hole for bolts to pass through and lock to the bed frame 100.
