Embodiment
Core of the present utility model is to provide a kind of pressure regulating switch, to reduce the load of pressure regulating switch.Another core of the present utility model is to provide a kind of water purifier with above-mentioned pressure regulating switch.
In order to make those skilled in the art person understand better the utility model scheme, below in conjunction with drawings and embodiments, the utility model is described in further detail.
Please refer to shown in Fig. 1-Fig. 3, the utility model embodiment discloses a kind of pressure regulating switch, comprise seesaw 1 and switch main body 2, and the spring that connects this seesaw 1 and switch main body 2, wherein, this spring comprises: the first spring 31 and the second spring 32, and the coefficient of elasticity of the first spring 31 is less than the coefficient of elasticity of the second spring 32, and one end of this first spring 31 connects the one in seesaw 1 and switch main body 2, and the other end connects seesaw 1 and another one in switch main body 2 or be connected one end of the second spring 32, the other end of the second above-mentioned spring 32 is fixed between seesaw 1 and switch main body 2.
In the application, spring is set to the spring of two kinds of different coefficient of elasticity, can increase the coefficient of elasticity of spring integral body, at pressure hour, the first spring 31 that coefficient of elasticity is little is first compressed, along with the second spring 32 that the increase coefficient of elasticity of pressure is large is compressed again, to slow down the movement velocity of seesaw 1, thereby extend the time of pressure switch closure, improved by the upper limit amount of water storage; And in the process disconnecting in pressure switch, due to the existence of the first less spring 31 of coefficient of elasticity, can reduce the coefficient of elasticity of whole spring, thereby reduce the pressure requirement of recoil of spring, thereby reduced by the lower limit amount of water storage, to sum up the application has improved the moisture storage capacity of water purifier.
The application's medi-spring is the spring of two kinds of different coefficient of elasticity, when seesaw is pressed, and when switch main body base internal water pressure degree changes, the first spring stress when hydraulic pressure is lower, when hydraulic pressure is higher, to be compressed into the second spring also stressed for the first spring.The low hydraulic pressure of such the first spring major control, the second spring is controlled high hydraulic pressure, so that the hydraulic pressure pressure differential range that pressure regulating switch is controlled is larger, prevents water purifier water pump frequent starting processed.
Please refer to shown in Fig. 1 and Fig. 2, in specific embodiment, one end of the first spring 31 is connected with switch main body 2, the other end is connected with seesaw 1, the second spring 32 is set in the first spring 31 outsides, preferably, the length of the second spring 32 is less than the length of the first spring 31, and after the first spring 31 is compressed to certain position, the second spring 32 starts compression.By above-mentioned setting, when pressing seesaw 1, first the first spring 31 compresses, and when being compressed to the height of the second spring 32, the second spring 32 and the first spring 31 are simultaneously compressed, owing to having increased by the second spring 32, therefore, increased the coefficient of elasticity of whole spring, therefore, can avoid seesaw 1 to be stressed excessive, and make the great problem of spring deflection.
In practice, also interchangeable for the relative position of the first spring 31 and the second spring 32, be about to the inside that the second spring 32 is arranged on the first spring 31.
The second spring 32 providing in the application is fixed on switch main body 2 by fixed head 5, particularly, this second spring 32 is fixed away from one end of seesaw 1, and the second spring 32 range switch main body 2 preset height, and the second spring 32 is set in the centre position of the first spring 31.In practice, this second spring 32 also can directly be fixedly connected with switch main body 2.
In order to realize the coefficient of elasticity of the first spring 31, be less than the coefficient of elasticity of the second spring 32, in preferred embodiment, the steel wire diameter of the first spring 31 is set to be less than the steel wire diameter of the second spring 32.The deformation quantity method that changes by the way spring is simple, easy operating.
During work, the water entering by inlet/outlet 5 applies certain pressure to the sealing ring 6 arranging, so that sealing ring 6 distortion exert pressure to seesaw 1, and promotes seesaw 1 and moves downward, thereby disconnect normally closed sensitive switch 7.And after sensitive switch 7 closures, water purifier carries out water storage, after disconnection, stop water storage.
Please refer to shown in Fig. 3, in another specific embodiment, one end of the first spring 31 is connected with switch main body 2, the other end is connected with the second spring 32, and the second spring 32 is connected with seesaw 1, the first spring 31 and the second spring 32 are arranged between switch main body 2 and seesaw 1 after connecting.Because the coefficient of elasticity of the second spring 32 is greater than the coefficient of elasticity of the first spring 31, therefore, can increase the coefficient of elasticity of whole spring.In compression process, because 31 coefficient of elasticity of the first spring are little, therefore, its deformation quantity is larger, and the coefficient of elasticity of the second spring 32 is larger, therefore, deformation quantity is little, thereby reduces the elastic module of whole spring, and don't can cause coefficient of elasticity to make to press very greatly difficulty.In practice, for the link position of the first spring 31 and the second spring 32, can also exchange, the first spring 31 connects seesaws 1, and the second spring 32 connecting valve main bodys 2.Coefficient of elasticity and length for the first spring 31 and the second spring 32 can be set according to actual requirement, and all in protection range.
Further, the first spring 31 is connected by connecting plate 4 with the second spring 32.During installation, one end of the first spring 31 is arranged on connecting plate 4, and one end of the second spring 32 is connected on connecting plate 4 equally, those skilled in the art are known, by connecting plate 4 is set, can improve the stability that the first spring 31 is connected with the second spring 32.
The utility model also provides a kind of water purifier, and it comprises pressure regulating switch, and this pressure regulating switch is disclosed pressure regulating switch in above-described embodiment, and therefore, the water purifier with this pressure regulating switch also has above-mentioned technique effect.
In this specification, each embodiment adopts the mode of going forward one by one to describe, and each embodiment stresses is the difference with other embodiment, between each embodiment identical similar part mutually referring to.
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the utility model.To the multiple modification of these embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
