Technical Field

[0001] The utility model relates to the technical field of power plugs, in particular to a protective cover for a water heater power plug. Background Art

[0002] A water heater is a device that uses electricity to heat cold water.

[0003] See also Figure 1 When using the water heater to boil water, you need to plug the power plug 1 into the socket 2, which is located on the wall 3. When using the hot water in the water heater, in order to avoid the risk of electric leakage, you need to unplug the power plug 1 from the socket 2.

[0004] Currently, a flap 31 is pivotally mounted on the wall. This flap 31 covers the power plug 1 only when the power plug 1 is inserted into the socket 2. When the power plug 1 is unplugged from the socket 2, the power plug 1 is not protected by the flap 31. When the water heater is unplugged to use the hot water in the water heater for bathing or washing, moisture can easily adhere to the unprotected power plug 1. When the moisture-covered power plug 1 is plugged into the socket 2 again, the risk of electric leakage increases.

[0005] Therefore, how to reduce the risk of water vapor adhering to the pins of the power plug and improve the safety of use is a technical problem that needs to be solved at present. Utility Model Content

[0006] In view of the above-mentioned deficiencies in the prior art, the present invention proposes a protective cover for a water heater power plug. The present invention can reduce the risk of water vapor adhering to the pins of the power plug, thereby improving the safety of use.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A protective cover for a power plug of a water heater comprises a power plug, which is plugged into a socket, which is arranged on a wall, a protective tube being provided on the outside of the socket, one end of which is connected to the wall, and a limiting structure being provided on the other end of the protective tube, a protective plate being provided on the back side of the power plug, which is slidably connected to the inner cavity of the protective tube, the limiting structure being used to prevent the protective plate from separating from the protective tube, a avoiding hole and two sealing gaskets for covering the avoiding hole being provided on the lower wall of the protective tube, a gap being provided between the two sealing gaskets, and the power cord of the power plug being slidably fitted into the gap.

[0009] Furthermore, the protective tube is provided with a mounting ring on the outer side of one end away from the limiting structure, and the mounting ring is connected to the wall via a fastener.

[0010] Furthermore, a sealing ring is provided on the mounting ring, a through hole is provided on the sealing ring, and the fastener is provided in the through hole.

[0011] Furthermore, the sealing ring is a rubber ring, and the sealing gasket is a rubber sheet.

[0012] Furthermore, the limiting structure includes a limiting vertical rod, a limiting horizontal rod, and a limiting baffle. There are two limiting vertical rods, the tops of the two limiting vertical rods are connected by a limiting horizontal rod, and a limiting baffle is provided between the limiting horizontal rod and the limiting vertical rod. The outer wall of the protective tube is provided with a sliding rail, and the limiting vertical rod and the sliding rail are vertically slidably matched.

[0013] Furthermore, the protection plate includes two splicing plates, and both splicing plates are connected to the back side of the power plug.

[0014] The utility model has the beneficial effects:

[0015] 1.

[0038] Example:

[0039] A water heater power plug protective cover, see Figure 1 , including a power plug 1, which is plugged into a socket 2 installed on a wall 3.

[0040] See also Figure 8 、 Figure 9 and Figure 10 , a protective tube 4 is provided on the outside of the socket 2. Figures 3 to 5 A mounting ring 41 is provided on the outer side of one end of the protective tube 4. The mounting ring 41 and the protective tube 4 are an integral structure. The mounting ring 41 is fixed to the wall 3 by a fastener. In this embodiment, the fastener can be a screw 411. A hole is provided on the mounting ring 41 (not shown in the figure). The screw 411 passes through the hole on the mounting ring 41 and is screwed into the wall 3, so that the mounting ring 41 is clamped between the head of the screw 411 and the wall 3, thereby realizing the installation and fixation of the protective tube 4 on the wall 3.

[0041] See also Figure 4 To improve sealing, a sealing ring 412 is affixed to the surface of mounting ring 41. This rubber ring is provided with a through-hole 4121 for receiving screws 411. When mounting ring 41 is secured to wall 3 using screws 411, sealing ring 412 is sandwiched between them. This prevents water on wall 3 from entering the gap between them, improving the sealing effect.

[0042] See also Figure 2 The back side of the power plug 1 is provided with a protective plate 5, which includes two splicing plates 51. The two splicing plates 51 are fixed to the back side of the power plug 1 by adhesive. The protective plate 5 is slidably matched with the inner cavity of the protective tube 4.

[0043] See also Figures 3 to 5 The protective tube 4 is provided with a limiting structure 6 at one end away from the mounting ring 41, and the limiting structure 6 is used to prevent the protective plate 5 from being separated from the protective tube 4. Figure 6 and Figure 7 The limiting structure 6 includes a limiting vertical rod 61, a limiting horizontal rod 62, and a limiting baffle 63. Two limiting vertical rods 61 are provided, with a limiting horizontal rod 62 positioned at the top of each limiting vertical rod 61. A limiting baffle 63 is positioned between the limiting horizontal rod 62 and the limiting vertical rod 61. The limiting vertical rod 61 is provided with a sliding hole 611. The limiting vertical rod 61, limiting horizontal rod 62, and limiting baffle 63 form an integral structure. A slide rail 43 is welded to the outer wall of the protective tube 4 at the end away from the mounting ring 41. The limiting vertical rod 61 and the slide rail 43 slide vertically together.

[0044] See also Figures 3 to 5The lower wall of the protective tube 4 is provided with an avoidance hole 44, and two sealing gaskets 45 are glued and fixed to the lower wall of the protective tube 4. The sealing gaskets 45 can be rubber gaskets. The two sealing gaskets 45 are used to cover the avoidance hole 44. A gap is provided between the two sealing gaskets 45. When the protective plate 5 on the back side of the power plug 1 is located inside the protective tube 4 and slides, the power cord 11 of the power plug 1 slides with the gap.

[0045] When assembling the limiting structure 6, the protective plate 5 and the protective tube 4: (1) insert the protective plate 5 installed on the back side of the power plug 1 into the interior of the protective tube 4 from the end of the protective tube 4 away from the mounting ring 41; (2) align the sliding hole 611 on the limiting vertical rod 61 with the sliding rail 43 on the side wall of the protective tube 4, and slide the limiting vertical rod 61 down along the sliding rail 43 until the limiting horizontal rod 62 abuts against the upper tube wall of the protective tube 4. At this time, the limiting baffle 63 can limit the protective plate 5 from falling from the end of the protective tube 4 away from the mounting ring 41, thereby improving the safety of the protective plate 5 sliding in the protective tube 4.

[0046] When separating the limiting structure 6, the protective plate 5 and the protective tube 4: (1) slide the limiting vertical rod 61 up along the slide rail 43 so that the limiting vertical rod 61 is separated from the slide rail 43, thereby separating the limiting structure 6 and the protective tube 4; (2) pull the protective plate 5 out of the protective tube 4 in a direction away from the power plug 1, thereby separating the protective plate 5 and the protective tube 4.

[0047] The working principle of this embodiment is as follows:

[0048] When using a water heater to boil water, you need to plug it in: Figures 9 and 10 The state of the power plug 1 changes, and the power plug 1 is pushed toward the socket 2, so that the pins of the power plug 1 are inserted into the sockets of the socket 2. During this process, the pins of the power plug 1 are in the closed environment formed by the protective tube 4, the protective plate 5, the sealing gasket 45 and the wall 3, and the power cord 11 of the power plug 1 is located in the gap between the two sealing gaskets 45. The sealing gasket 45 can improve the sealing effect of the protective tube 4.

[0049] When using the water heater for bathing or washing, you need to unplug the power cord: Figures 10 to 9 The state of the power plug 1 is changed, and the power plug 1 is pulled away from the socket 2, so that the pins of the power plug 1 are pulled out from the sockets of the socket 2. During this process, the pins of the power plug 1 are still in the closed environment composed of the protective tube 4, the protective plate 5, the sealing gasket 45 and the wall 3.

[0050] It can be seen from the above-mentioned plugging and unplugging process that during the process of plugging and unplugging the power plug 1, the pins of the power plug 1 can be located in a closed environment composed of the protective tube 4, the protective plate 5, the sealing gasket 45 and the wall 3, which can reduce the risk of water vapor adhering to the pins of the power plug 1 and improve the safety of use.

[0051] Since the protection plate 5 is in sliding cooperation with the protection tube 4 , when the power plug 1 is plugged in or out, the protection plate 5 can slide adaptively in the protection tube 4 without hindering the plugging or unplugging of the power plug 1 , thereby improving the flexibility of use.

[0052] The setting of the limiting structure 6 can prevent the protective plate 5 on the back side of the power plug 1 from detaching from the end of the protective tube 4 away from the mounting ring 41, thereby preventing the power plug 1 from detaching from the protective tube 4. When the water heater is not plugged in and used, the power plug 1 is supported by the protective tube 4, which makes it convenient for users to find and use the power plug 1, thereby improving the flexibility of use.

[0053] The limiting structure 6 and the protective tube 4 are easy to assemble and disassemble. It is only necessary to plug and unplug the limiting vertical rod 61 in the limiting structure 6 and the slide rail 43 on the outer wall of the protective tube 4, which is beneficial to improving the disassembly and assembly efficiency of the limiting structure 6 and the protective tube 4. Then, when the power plug 1 is inspected and maintained, the power plug 1 equipped with the protective plate 5 can be easily taken out of the protective tube 4 for inspection, which is more convenient to use.

[0054] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
