Digital spring mattress capable of arbitrarily adjusting hardness

Abstract

The invention discloses a digital spring mattress with adjustable hardness, comprising an upper mattress layer, a lower mattress layer and a frame body and a peripheral circle that connect the upper mattress layer with the lower mattress layer. A plurality of cylindrical spiral springs are respectively placed into cylindrical air bags provided with an air jet; one end of the cylindrical air bag is arranged on a hard board on the lower mattress layer, while the other end thereof is fixed on the upper mattress layer. An air pump is respectively sealed by and connected with the cylindrical air bags through air delivery pipes; a control unit can optionally control the air pump to charge or discharge the air bag, so as to change the deformation degree of the cylindrical spiral spring inside the cylindrical air bag by changing the pressure of the cylindrical air bag, thus realizing the target of adjusting the hardness of the mattress. Moreover, the digital spring mattress also produces different hardness for the left zone and the right zone of a double bed; therefore, the digital spring mattress fully satisfies the requirements of the user upon the hardness of the mattress, which can not only increase the comfort degree of the user but also can effectively improve the sleeping quality of the user.

Description

technical field [0001] The invention relates to a mattress, in particular to a spring mattress which can arbitrarily adjust the softness and hardness of the mattress according to the needs of users and display it in a digital manner. Background technique [0002] Usually, the mattresses used for sleep are divided into spring mattresses, sponge mattresses, air mattresses, etc., but spring mattresses and sponge mattresses in the prior art cannot adjust the hardness of the mattress. The softness and hardness can be adjusted within a limited range, but this kind of mattress has poor air permeability and comfort. The most widely used mattress is a spring mattress, such as a spring bed body disclosed in Patent No. ZL2004200721420. This kind of mattress is supported by many supporting springs distributed between the upper and lower cushion layers, and at the same time relying on the elastic force of the springs to prevent excessive deformation of the mattress, although the supporti...

[0002] Usually, the mattresses used for sleep are divided into spring mattresses, sponge mattresses, air mattresses, etc., but spring mattresses and sponge mattresses in the prior art cannot adjust the hardness of the mattress. The softness and hardness can be adjusted within a limited range, but this kind of mattress has poor air permeability and comfort. The most widely used mattress is a spring mattress, such as a spring bed body disclosed in Patent No. ZL2004200721420. This kind of mattress is supported by many supporting springs distributed between the upper and lower cushion layers, and at the same time relying on the elastic force of the springs to prevent excessive deformation of the mattress, although the supporting springs are surrounded by a single wire in a forward and reverse direction. It is made, and the cost is lower than that of the independent cylinder spring mattress. However, the common disadvantage of this improved mattress and the independent cylinder spring mattress is that the softness and hardness of the spring cannot be adjusted, because people usually buy and use the mattress for a long time , mattresses with different hardness may be needed in different periods. In addition, the existing double mattresses are all of the same hardness. If the two people sleeping on it need different hardness, it is unsatisfactory. Therefore, There is a need for a new type of mattress that can adjust the softness and hardness of the mattress arbitrarily to meet people's needs for improving sleep quality
