In one embodiment, the mesh plate 127 is connected to the case, and the mesh plate 127 may be plural, and the mesh plates 127 may be arranged in a square grid or other shape to filter the water in the water storage case 120.

Further, the water purification module further comprises a buffer waterway for reducing the flow rate of the water passing through the mesh plate 127, so that the time for the water to pass through the mesh plate 127 is prolonged, the mesh plate 127 can purify the water flowing through the mesh plate more sufficiently, and finally the water flowing out of the water quality filtering structure is purified sufficiently; after the purified water passes through the steam generating system 400 of the steam sterilizing cabinet, purer steam is generated, the sterilizing effect of the steam sterilizing cabinet is effectively improved, and meanwhile, the purified water cannot cause blockage, corrosion and other influences on a pipeline or a water box in the steam sterilizing cabinet, so that the service life of the steam sterilizing cabinet is prolonged.

The buffer waterway can be used for reducing the water flow rate in various ways, for example, the shape and the structure of the buffer waterway are arranged to change the flow track of water, and the kinetic energy loss of the water is caused when the water flow direction is changed, so that the water flow rate is reduced; in another embodiment, the flow rate of water can be directly reduced by arranging barriers such as protrusions in the flow channel; in yet another embodiment, the flow rate of water may also be reduced by modifying the slope of the flow path such that water flows through the flow path having an upward slope.

In this scheme, the shape of the buffer waterway is preferably a serpentine shape, for example, the buffer waterway is spiral, serpentine or other special-shaped, so that when water flows in the buffer waterway, large particulate matters in the water can be deposited to the bottom of the water storage box 120 in a natural precipitation manner, thereby improving the water purifying effect. The setting of buffering water route shape can be directly realized through the setting of runner shape, still can be through setting up the drainage piece that can change the water flow direction in original runner to realize the change of water flow direction. In an embodiment, the buffer waterway includes a plurality of baffles, and the baffles are staggered to form the serpentine buffer waterway; the baffle can be in a straight plate shape or a bent plate shape. The material and thickness of the baffle are not limited herein. Preferably, one end of the buffer waterway corresponds to the water outlet 121, and at least one mesh plate 127 is disposed at the water outlet 121, so that most of the water flowing out of the water outlet 121 can be purified under the combined action of the buffer waterway and the mesh plate 127, thereby improving the utilization effect of the buffer waterway and the mesh plate 127.

Specifically, the steam sterilizing cabinet comprises a cabinet body, a door body, a steam generating system 400 and a water box assembly 100. The cabinet body comprises an inner container 200 and a shell 300 arranged outside the inner container 200. Specifically, the inner container 200 has a disinfection chamber therein, and the door body can open or close the disinfection chamber; the water cartridge assembly 100 may be disposed between the inner container 200 and the outer case 300 or detachably coupled to the outside of the outer case 300 for delivering water to the steam generation system 400; the steam generation system 400 is used for processing water in the water box to form steam and delivering the steam into the disinfection cavity; the steam generating system 400 is disposed between the liner 200 and the outer case 300 to prevent the user from being scalded due to contact; the water outlet 121 of the water box assembly 100 and the steam generation system 400 may be connected directly or through a pipe.

In this solution, the box base 110 is connected to the liner 200 by means of a fastener, a screw, or the like, an inlet into which the water storage box 120 is inserted is provided on the surface of the liner 200, and the user pushes the water storage box 120 into the box base 110 from the inlet, so that the box base 110 is connected to the water storage box 120, and the water storage box 120 is fixed in the liner 200; the water storage cartridge 120 is pulled out of the inlet by pushing the water storage cartridge 120 again toward the inlet, thereby disengaging the cartridge holder 110 from the water storage cartridge 120.

The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
