[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model is provided with a filtering and water injection assembly. After the collection box is moved and fitted to the lower side of the filter box, the screw is rotated and moved to tighten. The movement of the tightening screw drives the moving bar to move. The movement of the moving bar drives the supporting block to move. When the supporting block moves and fits the lower side of the collection box, the rotation of the tightening screw is stopped. Subsequently, external water is input into the filter box through the water injection pipe. After passing through the filter screen, the water enters the water delivery mechanism in the cabinet through the pores on the filter screen. The sundries mixed in the water fall into the collection box through the opening for collection operation, thereby preventing the sundries mixed in the water from entering the water delivery mechanism, causing the water delivery mechanism components to be blocked, and affecting the use effect of the water delivery mechanism.

[0014] 2. The utility model is provided with a protection component. After the operator observes the water pressure and the water temperature, he pulls the positioning rod upwards. The movement of the positioning rod drives the external ring to move. The movement of the external ring squeezes the connecting spring, and then moves the protective cover toward the side strip. The movement of the protective cover drives the plug-in strip to move and plug into the inside of the plug-in slot. Then, the positioning rod is released. The connecting spring loses the external force and returns to its original state, driving the positioning rod to move and plug into the inside of the plug-in strip. The plug-in strip is positioned and fixed, and then the protective cover can be limited and fixed to ensure the stability of the connection between the protective cover and the side strip. Under the action of the protective cover and the side strip, the temperature-pressure integrated meter can be protected to prevent dust and other debris in the external environment from falling onto the temperature-pressure integrated meter, thereby ensuring the subsequent observation effect of the temperature-pressure integrated meter.
