Title: SPA Cushion

Description:
TECHNICAL FIELD 
     The present utility invention relates to the technical field of height-enhancing cushions, in particular to a SPA cushion. 
     BACKGROUND ART 
     A SPA cushion makes people feel more comfortable to sit on. Most SPA heightening cushions available on the market are inflated and lack of softness. Besides, air leakage and explosion often occurs, for it is not able to subject to the pressure of the whole body. Additionally, an inflatable SPA cushion is easy to float in the water, which makes it inconvenient to use in water environment. When users get up, it will float away. And when user wants to use it again, she or he has to pick it up and fix position again, which is quite cumbersome to use. 
     SUMMARY OF THE INVENTION 
     The main purpose of the utility invention is to provide a SPA cushion to solve the users&#39; problems of poor softness and comfort, easy air leakage, risk of explosion, and cumbersome use in water proposed in the above-mentioned background art. 
     In order to achieve the above purpose, the SPA cushion provided by the present utility invention consists of an outer jacket, the outer jacket is filled with an core, and the bottom of the core is provided with a counterweight. The outer jacket is a 3D mesh jacket, and the core also of 3D mesh material. There is non-slip rubber base at the bottom side of the outer jacket for increasing friction to prevent moving easily, and there are four mounting holes for installing suction cups at the bottom side of the outer jacket. 
     Preferably, the outer jacket is provided with a handle or hanger. 
     Preferably, the counterweight include glass beads or stone or marble beads. 
     Preferably, the top of the outer jacket is provided with a zipper. 
     Preferably, the bottom side of the outer jacket is provided with a Non-slip rubber base. 
     Compared with the prior art, the beneficial effects of the present utility invention are: 
     The SPA cushion provided by the present utility invention is more soft and comfortable, and offers significant support for buttock. At the same time, the outer jacket and the core are made of 3D mesh material, which is a breathable, water-permeable, and quick-drying fabrics. As a result, the SPA cushion will dry up quickly after use in water. 
     The SPA cushion provided by the present utility invention is used in the water, the counterweight will drive it sink quickly by itself, and the cushion will not move or float, as a result, it is more convenient for user to sit on again. 
     The SPA cushion provided by the present utility invention is of high quality and more safe to use. The core is not inflatable, thus, problems such as air leakage and explosion will not occur.

     Embodiments 
     The solutions in the embodiments of the present utility invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments. The following are just preferred embodiments of the present invention, and do not limit the scope of the present utility invention. Any equivalent structure transformation made in accordance with the specification of the present utility invention and the content of the drawings under the inventive concept of the present utility invention or directly or indirectly applied to other related fields is included in the scope of patent protection of the present utility invention. 
     It should noted that if one embodiment of the present invention comprises a direction indication (e.g., “upper, lower, front, rear, left, right, top, bottom, inside . . . ”), the direction indication is only used to interpret the relative positional relationship among various parts and their movement under a certain attitude (see the Drawings). It is only for the convenience of simplifying the description, rather than indicating or implying that the indicated device or element must have a specific orientation, or are constructed and operated in a specific orientation, and therefore cannot be limited the scope of patent protection of the present utility invention. 
     In one embodiment,  FIGS. 1 ˜ 5 , the present utility invention provides a solution: a SPA cushion, including an outer jacket  1 , the outer jacket  1  is filled with a core  6 , and the bottom of the core  6  is provided with counterweight  7 , which can make the cushion sink easily by itself in the water. The outer jacket  1  is made of a 3D mesh fabric, and the core  6  is made of 3D mesh material or a polymer air fiber material. The 3D mesh material is high of air and moisture permeability and redistribution of compression pressure, thus, the SPA cushion is quick-drying when get out from the water. The bottom of the outer jacket  1  is provided with non-slip rubber base  5  for increasing friction, and the non-slip rubber base  5  consists of rubber dots. In addition, there are four mounting holes  8  at the bottom side of the outer jacket for installing the suction cups, which fixes the position of the SPA cushion without moving or floating easily. 
     The outer jacket  1  is provided with a handle  2  or a hanger  3 , the counterweight  7  can be glass beads or stones or marble beads. And a zipper  4  is arranged at the top of the outer jacket  1  to facilitate the removal of the core  6  from the outer jacket  1 . The bottom of the jacket  1  is provided with non-slip rubber base with robber dots. 
     Operating principle: Outer jacket  1  and the core  6  which is of high air and moisture permeability and redistribution of compression pressure, so the SPA cushion can be quick-drying and more comfortable to support for the buttock. The SPA cushion will quickly sink in the water by itself due to the weight of counterweight  7 . Moreover, it is easy to fix itself in right direction and will not float or move because of the non-slip rubber base  5  at the bottom of the outer jacket  1 , or suction cups on the mounting holes  8 .
