Detailed Description
The utility model will now be described in further detail with reference to the accompanying drawings and examples, which are simplified schematic drawings and illustrate only the basic structure of the utility model in a schematic manner, and thus show only the constituents relevant to the utility model. It should be noted that the terms "front," "back," "left," and "right" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.
As shown in fig. 1 to 3, a sofa with adjustable softness comprises a base 1, a backrest 2, armrests 3, a controller 4, an operation screen 5 and legs 6. The base 1 is in a cuboid structure; the backrest 2 is arranged at the long edge of one side of the upper surface of the base 1; two handrails 3 are arranged and symmetrically arranged at a pair of short edges on the upper surface of the base 1; the landing leg 6 sets up a plurality ofly, and the equipartition is in the bottom of base 1.
The base 1 is provided with a cavity with an upward opening, an elastic support 12 and an air pump 13 are arranged in the cavity, the opening of the cavity is fixedly connected with a flexible cushion 11, and the opening of the cavity is sealed by the flexible cushion 11.
The elastic support 12 is a vertically arranged hollow cylinder, is positioned below the flexible cushion 11 and abuts against the lower surface of the flexible cushion 11 from bottom to top; the side surface of the elastic support 12 is provided with a corrugated structure 121 surrounding the periphery of the elastic support, and the wave-shaped extending direction of the corrugated structure 121 is parallel to the axial direction of the elastic support 12; the bottom of the elastic support 12 is provided with an air valve 122, correspondingly, the bottom of the base 1 is provided with a through hole matched with the air valve 122, so that the hollow structure of the elastic support 12 is communicated with the outside; meanwhile, the elastic support 12 is further provided with a pressure detection device 123, and the pressure detection device 123 is a conventional air pressure detector and is used for detecting the air pressure in the hollow structure of the elastic support 12; preferably, the elastic support 12 is made of silica gel or latex; the gas valve 122 is a solenoid valve.
The air pump 13 is positioned below the backrest 2 and at the same horizontal position as the elastic support 12. The air pump 13 is communicated with the elastic support 12 through an air conveying pipe 14 and is used for inflating the hollow structure of the elastic support 12.
The controller 4 is a conventional PLC controller, is also arranged in the cavity of the base 1, is connected with the air pump 13, the air valve 122 and the pressure detection device 123 through conventional electrical connection or other conventional connection modes, and is used for receiving and recording a detection value of the pressure detection device 123 and controlling the air pump 13 and the air valve 122; the operation panel 5 is disposed inside the armrest 3 and is connected to the controller 4 by means of a conventional electrical connection.
When in use, a user sets a target air pressure value (or air pressure level) in the hollow structure of the elastic support 12 through the operation screen 5; the controller 4 controls the operation of the air pump 13 to realize inflation after receiving the instruction, and controls the opening and closing of the air valve 122 to realize deflation, thereby realizing the adjustment of the air pressure in the hollow structure of the elastic support 12. Meanwhile, the pressure detection device 123 detects the air pressure in the hollow structure of the elastic support 12 and feeds the air pressure back to the controller 4; when the target value (or target level) is reached, the operation of the air pump 13 is stopped or the air valve 122 is closed. The bearing capacity of the elastic support 12 can be adjusted by adjusting the target air pressure value in the hollow structure of the elastic support 12, so that the buffering amplitude and capacity of the elastic support 12, namely the hardness degree, are adjusted when the gravity is transmitted to the elastic support 12 through the flexible cushion 11.
The conventional inflatable air bag has smooth outer wall, so that the outer wall of the inflatable air bag is often greatly dragged when the inflatable air bag is compressed and deformed by gravity, and the service life and the compression smoothness are adversely affected; but also more pronounced when the air pressure inside the inflatable bladder is lower (i.e., the sofa behaves softer). The side surface of the elastic support 12 of the utility model is provided with the corrugated structure 121, so when the elastic support 12 is compressed and deformed under the action of the body weight force, the side wall of the elastic support 12 is less dragged, thereby the service life is longer, especially the service life under the condition that the air pressure in the hollow structure is lower (namely the sofa is softer); meanwhile, the elastic support 12 is compressed more smoothly due to the presence of the bellows structure 121 than the conventional air bag.
It is of course to be noted that the core object of the utility model can also be achieved in a manual manner, instead of using the controller 4 and the operating screen 5. The method specifically comprises the following steps: manually measuring the air pressure value inside the hollow structure of the elastic support 12 by the pressure detection device 123; then, the air pressure value in the hollow structure of the elastic support 12 is adjusted to a target value by manually opening the air valve 122 to deflate or manually starting the air pump 13 to inflate; then the air valve 122 or the air pump 13 is closed to complete the operation.
In addition, the water bags 7 are respectively arranged on the upper surface of the flexible cushion 11 and the outer side surface of the backrest 2, so that the local softness of a person sitting on the sofa can be increased, and the comfort level of the sofa is improved. The water bags 7 are provided with water gaps 71 and air exhaust holes, so that water can be conveniently filled or drained inwards. Preferably, the water sac 7 is of a double-layer structure, water is arranged inside the inner layer, and a sodium polyacrylate layer 72 is arranged between the two layers; because of its high water absorption capacity, the sodium polyacrylate layer 72 can effectively absorb water to avoid wetting other parts of the sofa in the event of an accident by rupturing the water bladder 7. Sodium polyacrylate can be placed between the two layers of the water bladder 7 by way of being packed into a cotton cloth bag.
In light of the foregoing description of the preferred embodiments of the present invention, it is to be understood that various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the utility model. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
