Description

Water purifier Technical Field The utility model relates to a water purifier. Background With the improvement of public drinking water demands, commercial water purifiers are widely applied to scenes such as offices, shops and large-scale entertainment facilities. Such devices typically employ removable door panel structures to allow a user to quickly service a filter cartridge, replace consumables, or clean internal components. At present, the buckle connection is a mainstream installation scheme because of the characteristics of convenient operation and no auxiliary tool. The door plate is used as a core component of the appearance of the equipment, not only needs to meet the maintenance requirement of frequent disassembly, but also needs to bear the self weight and the external mechanical load (such as the impact force of opening and closing the door) for a long time. Conventional snap-fit connection schemes are difficult to meet long-term use needs. The hook-shaped structure of the buckle repeatedly bears bending stress in the process of carrying out high-frequency disassembly under the condition of bearing the weight of the door plate, so that plastic deformation is easy to occur in the material, and further stress relaxation is caused. The long-term cantilever load caused by the dead weight of the door plate can cause microcracks in the stress concentration area of the root parts of the buckles, the door plate can be not tightly covered after long-term use, even brittle fracture can be caused, the door plate can be accidentally dropped, and the safety of equipment and user experience are endangered. Disclosure of utility model The utility model aims to overcome the defect that a buckle for connecting a door plate is easy to fail under the condition of bearing the gravity of the door plate for a long time in the prior art. The utility model solves the technical problems by the following technical scheme: The utility model provides a water purifier, which comprises a water purifier shell, wherein the water purifier shell comprises an opening, a door plate covered on the opening, a clamping piece is arranged on the door plate and used for enabling the door plate to be clamped on the water purifier shell, the water purifier further comprises a pressing device, the clamping piece and the pressing device are oppositely arranged on the door plate, the pressing device and the door plate are elastically connected to switch a first position and a second position of the door plate, the first position is that the door plate is abutted to the wall surface of the opening, the clamping piece is clamped on the water purifier shell, and the second position is that the door plate is separated from the wall surface of the opening, and the clamping piece is separated from the water purifier shell. In the scheme, on the basis of connection of the clamping piece, the pressing device elastic support door plate is additionally arranged, so that the door plate is maintained at a first position, namely in an installation state. The door plate is pressed by the pressing device to apply a supporting force to the door plate, so that the side edge of the door plate away from the pressing device is propped against the wall surface of the opening, and when the door plate is horizontally arranged, the friction force between the door plate and the wall surface of the opening can be increased under the action of the supporting force, so that the connecting load born by the clamping piece is relieved. When the door plate is arranged vertically or obliquely, the supporting force provided by the pressing device can directly offset part of the gravity of the door plate, so that the service life of the clamping piece is prolonged. When the door plate is in the second position, namely in the dismounting state, the door plate is driven to elastically compress by pushing the door plate downwards, a space for giving way appears above the door plate, and the clamping piece is separated from the shell of the water purifier, so that the door plate can be dismounted by simply turning the door plate. By adopting the structure, the clamping piece can be effectively prevented from bearing excessive door plate weight for a long time, and further the risk of failure of the clamping piece is reduced in long-term use. Preferably, the setting direction of the door panel is at least partially coincident with the vertical direction, the presser is arranged at the bottom of the door panel, and the clamping piece is arranged above the presser. In this scheme, make the presser support the door plant at least in vertical direction through above-mentioned setting, even the supporting force that the presser provided has the component in the direction of gravity that offsets the door plant to let the weight that the presser supported the door plant in order to the connecting load of the furthest buffering joint spare. Preferably, the presser comprises a presser hou
