[0043] In order to facilitate maintenance of the electric water heater, the hidden cover 300 and the anti-electricity wall cover 200 can be detachably connected, but the existing hidden cover 300 and the anti-electricity wall cover 200 are difficult to disassemble. Figure 1 and Figure 2 The electric water heater further comprises a snap-in structure 400, and both the anti-electricity wall cover 200 and the hidden cover 300 are snap-in connected with the snap-in structure 400, thereby realizing a detachable connection between the anti-electricity wall cover 200 and the hidden cover 300.

[0044] The electric water heater is provided with a clamping structure 400, and the anti-electricity wall cover 200 and the hidden cover 300 are connected by the clamping structure 400. The clamping structure 400 and the anti-electricity wall cover 200 and the clamping structure 400 and the hidden cover 300 are all clamped, which is very convenient to operate. The user can assemble and disassemble the hidden cover 300 by himself, which is convenient for later maintenance and replacement.

[0045] To further facilitate assembly, the clamping structure 400 is clamped with the anti-electricity wall cover 200 along a first direction, and the hidden cover 300 is also clamped with the clamping structure 400 along the first direction, wherein the first direction is the arrangement direction of the anti-electricity wall cover 200 and the hidden cover 300. Through the above arrangement, sufficient operating space can be provided for clamping, and it is more convenient for operators to apply force during assembly. When installing the anti-electricity wall cover 200 and the hidden cover 300, the clamping structure 400 can be placed on the anti-electricity wall cover 200 first, and the clamping structure 400 can be pressed to clamp and fix with the anti-electricity wall cover 200, and then the hidden cover 300 can be placed on the anti-electricity wall cover 200, and the hidden cover 300 can be pressed to complete the clamping and fixing of the hidden cover 300 and the clamping structure 400, and then the assembly can be completed.

[0046] See also Figures 2 to 6 The anti-electrical wall cover 200 is provided with a plug-in protrusion 210 , and the clamping structure 400 can be sleeved on the plug-in protrusion 210 and clamped with the plug-in protrusion 210 .

[0047] When connecting the anti-electricity wall cover 200 and the hidden cover 300, the clamping structure 400 is firstly placed on the plug-in protrusion 210, and then the clamping structure 400 is pressed to clamp and fix the clamping structure 400 and the plug-in protrusion 210. Then, the hidden cover 300 is clamped with the clamping structure 400, and the connection between the anti-electricity wall cover 200 and the hidden cover 300 is completed.

[0048] like Figure 4 and Figure 5As shown, the plug-in protrusion 210 includes a plug-in column and a convex rib 211. The bottom end of the plug-in column is connected to the anti-electric wall cover 200. The top end of the plug-in column is provided with a convex rib 211. The convex rib 211 is provided in the radial direction of the plug-in column so that a step surface is formed between the bottom of the convex rib 211 and the plug-in column. An abutment sheet 411 is provided in the clamping structure 400. The abutment sheet 411 can abut against the bottom surface of the convex rib 211 to prevent the plug-in protrusion 210 from being disengaged from the clamping structure 400.

[0049] like Figure 5 As shown, a slot 430 is provided in the clamping structure 400, and a contact piece 411 is located on the inner wall of the slot 430 and protrudes toward the center of the slot 430. When the plug-in protrusion 210 is matched with the clamping structure 400, the plug-in protrusion 210 extends into the slot 430 from the notch at the bottom end of the clamping structure 400; during this process, the plug-in protrusion 210 contacts the contact piece 411 and applies a contact force to the contact piece 411, so that the contact piece 411 is deformed and compressed, so that the convex ridge 211 on the plug-in protrusion 210 passes over the contact piece 411 and enters the interior of the slot 430. Afterwards, the contact piece 411 is no longer squeezed and resets, and the contact piece 411 abuts against the bottom end of the convex ridge 211 to prevent the plug-in protrusion 210 from escaping from the slot 430.

[0050] Optionally, convex ridges 211 are provided on two opposite side surfaces of the plug-in column, and correspondingly, abutment sheets 411 are provided on two opposite inner walls of the clamping structure 400. When the plug-in protrusion 210 and the clamping structure 400 are assembled, the plug-in protrusion 210 is inserted into the inside of the clamping structure 400, and after the convex ridges 211 on both sides of the plug-in protrusion 210 pass through the gap between the abutment sheets 411 on both sides from bottom to top, the top of the abutment sheet 411 abuts against the bottom of the convex ridges 211, so that the clamping structure 400 will not withdraw from the plug-in protrusion 210.

[0051] Furthermore, the clamping structure 400 is provided with an observation hole 420 communicating with the slot 430 . After the abutting piece 411 abuts against the convex ridge 211 , the observation hole 420 faces the convex ridge 211 .

[0052] When the clamping structure 400 and the plug-in protrusion 210 are connected, the operator can see whether the plug-in protrusion 210 is installed in place through the observation hole 420 to ensure the firmness of the connection. In addition, the observation hole 420 can also provide deformation space for the abutment sheet 411, so that the convex ridge 211 can pass over the abutment sheet 411 and extend into the slot 430.

[0053] See also Figure 2 , Figure 6-Figure 8The bottom of the hidden cover 300 is provided with a connecting cap 310, and the connecting cap 310 and the hidden cover 300 are surrounded to form a plug-in cavity, and the clamping structure 400 can be inserted into the plug-in cavity and clamped with the connecting cap 310.
