Description

Technical Field

[0001] The utility model belongs to the technical field of water leakage protection, in particular to a water leakage protection device for a pure water system. Background Art

[0002] The existing water leakage protection device is a non-powered water leakage protection device: it mainly consists of four parts: the water inlet, the water outlet, the valve between the inlet and the outlet, and the induction cotton. When the water purifier works normally, the water inlet and the water outlet are connected; when the water purifier leaks, the induction cotton will absorb water and expand to the valve between the inlet and the outlet, thereby cutting off the water inlet and playing the role of water leakage protection.

[0003] However, the induction cotton of the existing power-free water leakage protection device needs to absorb a certain amount of water and have a certain degree of expansion to play the role of water leakage protection. Therefore, it is easy to happen that the valve cannot be cut off due to insufficient expansion of the induction cotton. In addition, this water leakage protection device is only suitable for small pure water machines with small inlets and outlets, and cannot be used on large pure water machines.

[0090] A driving member 17, wherein the driving member 17 is used to drive the bidirectional screw 14 to rotate;

[0091] The clamping member 18 is fixed to one end of the fourth connecting rod 16 located outside the mounting base 1 .

[0093] like Figure 3 As shown, as another preferred embodiment of the utility model, a one-way movement limiting mechanism 400 is connected between the moving seat 15 and the inner wall of the mounting base 1, and the one-way movement limiting mechanism 400 includes:

[0094] Fixed sleeve 23;

[0095] A first elastic member 24, wherein the first elastic member 24 is fixed to the inner wall of the fixing sleeve 23;

[0096] A moving block 25, wherein the moving block 25 is fixedly connected to an end of the first elastic member 24 away from the inner wall of the fixing sleeve 23, and the moving block 25 slides inside the fixing sleeve 23;

[0097] A seventh connecting rod 26, wherein the seventh connecting rod 26 is slidably connected to the fixing sleeve 23 and fixedly connected to the moving block 25;

[0098] The moving block 25 is connected with a limiting component for limiting its position.

[0099] In the embodiment of the utility model, when in use, the bidirectional screw 14 drives the moving seat 15 to move, the moving seat 15 drives the seventh connecting rod 26 to move, and the seventh connecting rod 26 drives the moving block 25 to move. At this time, the end of the moving block 25 away from the seventh connecting rod 26 is limited by the limiting assembly, so that it cannot be reset and moved, thereby ensuring that the clamping effect of the moving seat 15, the fourth connecting rod 16, and the driving member 17 is stable.

[0100] In one case of this embodiment, the limiting component includes:

[0101] A limiting plate 27, wherein the limiting plate 27 is slidably disposed in the fixing sleeve 23;

[0105] In this embodiment, when in use, the position of the eighth connecting rod 28 is controlled by the power unit 300, that is, the position of the limit plate 27 is controlled, so that the elastic limit unit 500 in the limit plate 27 limits the end face of the moving block 25, and the moving block 25 can squeeze the elastic limit unit 500 to contract through the first inclined surface, and no movement obstacle will be generated. By setting the eighth connecting rod 28 to be driven by the power unit 300, it is possible to adjust the position of the limit plate 27 when draining water, that is, when maintaining the pure water machine, so that the moving block 25 can be reset, that is, the clamping member 18 can release the clamping of the pure water machine, so as to facilitate maintenance by maintenance personnel.

[0111] The stopper 31 is provided with a second inclined surface matched with the first inclined surface.

[0112] In the embodiment of the utility model, when in use, the moving block 25 squeezes the second inclined surface through the first inclined surface, so that the stopper 31 drives the slider 30 to move into the slide groove 29. At this time, the second elastic member 32 is squeezed. When the moving block 25 passes over the stopper 31, the elastic force of the second elastic member 32 drives the slider 30 and the stopper 31 to reset, thereby limiting the end face of the moving block 25, so that the moving block 25 cannot be reset and moved, thereby ensuring that the clamping effect of the moving seat 15, the fourth connecting rod 16, and the driving member 17 is stable.
