[0011]

[Embodiment of the invention]

 4 and 5 are a perspective view and a sectional view of the present invention. The waterbed of the present invention includes a waterbed main body 10, a buffer sponge 20, a strip 30, an air sac 40, and a plug 50. The features of the entire structure will be described below.

A buffer sponge 20 is placed inside the water bed main body 10, and the inside of the water bed main body 10 is divided into three hydropouch chambers 11 in the longitudinal direction, and the buffer sponge 20 is divided into one main sponge body 21 and two. The main sponge body 21 and the sub-sponge body 22 are each provided with three penetrating circular holes 211 and 221, and three air bladders 40 are accommodated therein. A recess 212 having an opening at the bottom is provided below the main sponge body 21, and one plastic film 213 is formed on each of both longitudinal end faces of the main sponge body 21 by hot-melt bonding. The periphery of the sealing piece 32 in the pieces 30 on both sides in the longitudinal direction of the water bed 10 is joined to the inner periphery of the water bed main body 10 by high frequency. Independent air gaps 12 for accommodating a sponge are formed between both ends of the bed body 10 and the sealing piece 32 so that the water bed body 10 can maintain a well-shaped edge. The space between the partition 32 and the ventilation partition 31 is the air chamber 13, and the ventilation partition 31 is provided with three air inlets 311, and between both ends of the plurality of air sacs 40 and the three air inlets 311. Are subjected to high frequency welding to form the overall structure of the present invention.

When water is injected into the water bed main body 10 using the water tap 52 in the plug body 50 and water enters the water sac chamber 11, the buffer sponge 20 absorbs water and fills the water sac chamber 11. After the water injection is completed, the gas is directly injected into the three air sacs 40 from the air inlets 311 through the air chamber 13 having a sponge inside, on both sides of the air inlet 51, and at this time, the gas in the air sacs 40 is injected. The volume of water occupying the interior of the sac chamber 11 is determined by the air volume, whereby the hardness of the water bed main body 10 is adjusted, and thus the water bed main body 10 of the present invention can be adjusted to the required hardness of the user. It can be adjusted.

The air sac 40 is provided in the buffer sponge 20 of the water sac chamber 11, and when the water bed body 10 receives pressure, pressure is generated to directly transfer the water in the water sac chamber 11 to the buffer sponge 20. At this time, the pressure applied to the bladder chamber 11 presses the three air bladders 40, and the gas density in the three air bladders 40 increases to reduce the volume, buffer the pressure and prevent rupture. In this way, not only the effect of preventing the water in the water sac chamber 11 from oscillating can be obtained, but also the effective use of the plastic film 213 on the adjacent interface between the main sponge body 21 and the sealing strip 32 in the buffer sponge 20. The vibration wave and the acting force generated during 11 are buffered, and the working energy is absorbed when water passes through the gap of the buffer sponge 20, so that the effect of pressure drop is obtained. In addition, the elastic support of the buffer sponge 20 provides an auxiliary support function, so that the water bed of the present invention is hardly damaged and has high stability.

Regarding the use method of the present invention during production and production, please refer to FIGS. 6 and 7 show an embodiment of the combination of the structural materials of the present invention. When using the waterbed body 10 of the present invention in which the above-described combination is completed, the waterbed body 10 of the present invention can be placed in a separately provided waterbed seat body 60 by using a simple manufacturing method. By using the water bed body 10 of the present invention, a single bed or a double bed type water bed can be manufactured. When manufacturing a bed of a double form or more, it is only necessary to extend a water bed of the same form with the same structure, which is convenient for producing a water bed of a different size.

[0016]

[Effect of the invention]

 The present invention has achieved the following effects. 1. In the present invention, the water bed body is provided with a plurality of bladder chambers that divide the water bed body in a longitudinal direction, and a plurality of air bladders are provided in the water bed body, and the impact force and vibration when receiving pressure are provided. Waves can be reduced. For example, when the pressure is 15 pounds, a conventional water bed is directly subjected to a pressure of 15 pounds, and it is easy for the water bed to oscillate, rupture or break due to shock and vibration waves, and to cause water leakage. However, in the present invention, when the water bed is under pressure, the pressure is distributed evenly to the buffer sponge and the air sac in the pressurized sac chamber, and the gas density increases due to the compression of the air sac. The reduced volume provides an effective cushioning effect and a pressure drop effect. For this reason, the present invention is considered to be hardly damaged and extremely stable. 2. In the present invention, the water bed body is divided into a plurality of bladder chambers by the buffer sponge, and after the water is injected into the bladder chambers, the hardness of the water bed body can be adjusted by the filling amount of the air bag. In other words, if 90% of water is injected into the water bed body and the remaining space is 10%, if 15% of gas is injected into the air sac, the gas presses the water to form a full water bed, The water bed has elasticity, is firmly in contact with the body, can be adjusted to any hardness, and is less likely to swing. 3. The present invention can provide a single bed, a double bed, or a multi-person bed by combining water beds of the same standard with different water bed seats. 4. The present invention has a temperature adjustment function by installing the heating parts used in general water beds on the water bed body. As described above, the present invention is stable and does not easily generate oscillation, has a pressure buffering effect, is easy to manufacture, can save manufacturing costs, has both practicality and novelty, and has industrial utility value. It can be said that this is a device having.
