[0052] Specifically, the handle portion 4 can be arranged at any position of the edge of the decorative cover 31, and as a preferred embodiment, as shown in FIG. Figure 2 and Figure 3As shown, the hand-grip portion 4 is arranged at the bottom of the end cover assembly 3, and the bottom edge of the front cover 32 is bent toward the direction of the rear cover 33 so that the hand-grip cavity gradually increases from top to bottom. It can be understood by those skilled in the art that the hand-grip portion 4 is arranged at the bottom of the end cover assembly 3 so that the hand-grip portion 4 is in a position that is not easily seen directly. Only when the operator leans over and looks up from the bottom of the water purifier can the position of the hand-grip portion 4 be seen. Therefore, the hand-grip portion 4 forms a hidden design, which helps to improve the aesthetics; the bottom edge of the front cover 32 is bent toward the direction of the rear cover 33 so that the hand-grip cavity gradually increases from top to bottom, which is convenient for the operator to easily insert his fingers into the hand-grip cavity by feeling in the absence of vision to disassemble the front cover 32, thereby improving the convenience of operation.
[0053] As a preferred embodiment of the present application, Figure 5 , Figure 6 , Figure 7 , Fig. 9 and Fig.10 As shown, the decorative cover 31 is provided with a buckle protrusion 312, and the front cover 32 is provided with a buckle hole 321 matched with the buckle protrusion 312. The decorative cover 31 is detachably mounted on the front cover 32 through the cooperation between the buckle protrusion 312 and the buckle hole 321. The decorative cover 31 is detachably mounted on the front cover 32 through the cooperation between the buckle protrusion 312 and the buckle hole 321, so that the decorative cover 31 is easy and quick to install and can be disassembled and assembled by hand. Moreover, when the operator inserts his finger into the buckle hand cavity and applies force to the decorative cover 31 to remove the cover, it is not easy for the decorative cover 31 to be loosened from the front cover 32. At the same time, it is also convenient to regularly remove the decorative cover 31 to clean dust and dirt, so as to maintain the cleanliness of the decorative cover 31.
[0054] As a preferred embodiment of this implementation, Figures 4 to 7 As shown, the inner surface of the decorative cover 31 is provided with a protruding inner boss 313, the buckle boss 312 is formed on the inner boss 313 and extends downward, the outer surface of the front cover 32 is provided with a protruding outer boss 322, the buckle hole 321 is formed on the outer boss 322 and opens upward, and the decorative cover 31 is installed from top to bottom so that the buckle boss 312 and the buckle hole 321 are matched. When installing, the decorative cover 31 is taken above the front cover 32, and the buckle boss 312 on the decorative cover 31 is aligned with the buckle hole 321 below, and then the decorative cover 31 is moved down until the buckle boss 312 and the buckle hole 321 are matched, at which time the inner boss 313 abuts against the upper side of the outer boss 322 and is limited, so that the decorative cover 31 can be assembled in place. In addition, when the decorative cover 31 is installed, the inner boss 313 and the outer boss 322 are hidden behind the decorative cover 31, achieving the effect of hiding ugliness.
[0055] Furthermore, if Figure 4As shown, at least one side of the inner boss 313 is provided with a guide rib 314 extending in the vertical direction. When the decorative cover 31 is installed from top to bottom, the guide rib 314 slides along the surface of the outer boss 322 to guide the buckle protrusion 312 to cooperate with the clamping hole 321. It can be understood by those skilled in the art that, in the process of installing the decorative cover 31 toward the front cover 32, the inner boss 313 and the outer boss 322 are hidden at the rear side of the decorative cover 31, and the operator needs to install them without vision. The buckle protrusion 312 and the clamping hole 321 are not easy to align, and the installation is difficult. Therefore, by setting the guide rib 314, when the decorative cover 31 is installed from top to bottom, the buckle protrusion 312 is guided to cooperate with the clamping hole 321, ensuring that the buckle protrusion 312 is aligned with the clamping hole 321 and quickly cooperates, which greatly reduces the installation difficulty of the decorative cover 31.
