[0002] A wall-mounted electric water heater is a hot water supply device designed specifically for homes or small spaces. It is typically installed on a wall to save floor space. The water heater usually includes an outer casing, which is typically made of stainless steel, galvanized steel, or high-strength plastic. The casing is designed not only to protect the internal components and provide waterproofing and moisture resistance, but also to improve heat retention and coordinate with the home environment, enhancing the overall aesthetics.

[0003] Existing wall-mounted electric water heaters typically have sharp edges on their outer casing. Users usually attach protective pads to the casing for protection. However, due to changes in temperature and humidity during use, the protective pads can easily slip off. The lack of proper securing of the protective pads can lead to accidental injuries when they slip off. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a wall-mounted electric water heater shell, which aims to improve the problem of the lack of a protective pad for fixing the electric water heater shell during use.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A wall-mounted electric water heater casing includes a housing. The inner wall of the housing has a slot, and the outer wall of the housing has a protective pad. A hollow block is fixedly connected inside the protective pad, and a push rod is slidably connected inside the hollow block. A connecting plate is fixedly connected to the upper surface of the push rod, and a first inclined block is fixedly connected to the upper surface of the connecting plate. A second inclined block is slidably connected to the upper surface of the first inclined block, and a third inclined block is fixedly connected to the right outer wall of the second inclined block. A telescopic rod is fixedly connected to the front outer wall of the third inclined block, and a support block is fixedly connected to the middle outer wall of the telescopic rod. A spring is fixedly connected to the rear outer wall of the support block, and the other end of the spring is fixedly connected to the front outer wall of the third inclined block. The rear outer wall of the third inclined block is slidably connected to the inner wall of the slot. A support assembly is provided on the inner wall of the wall to support the housing.

[0007] Preferably, the support assembly includes a fixing frame, the rear outer wall of which is fixedly connected to the inner wall of the wall, and the front outer wall of which is fixedly connected to a semi-circular plate.

[0008] Preferably, the outer wall of the inclined block three is disposed on the inner wall of the shell, the right outer wall of the inclined block two is slidably connected to the outer wall of the support block, the outer wall of the inclined block three is slidably connected to the inner wall of the hollow block, the outer wall of the inclined block three is slidably connected to the inner wall of the support block, and the outer wall of the support block is fixedly connected to the inner wall of the hollow block.

[0009] Preferably, a slider is slidably connected to the outer wall of the semicircular plate, the upper surface of the slider is fixedly connected to the lower surface of the housing, and a handle is rotatably connected to the inside of the slider.

[0010] Preferably, a worm gear is fixedly connected to the rear outer wall of the handle, and sleeves are rotatably connected to both ends of the worm gear.

[0011] Preferably, the outer wall of the sleeve is fixedly connected to the inner wall of the slider, and the outer wall of the worm is engaged with a worm wheel.

[0012] Preferably, a semi-cylinder is fixedly connected inside the worm gear, and both ends of the semi-cylinder are fixedly connected to the outer wall of the semi-circular plate.

[0013] Preferably, the inner wall of the slider is fixedly connected to a limiting block, and the outer wall of the limiting block is slidably connected to the inner wall of the semicircular plate.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by pushing the push rod, the connecting plate and the first inclined block move upward, which in turn causes the second and third inclined blocks to slide forward. The third inclined block slides out of the inner wall of the slot and no longer restricts the hollow block, thus quickly fixing and disassembling the protective pad, making it easy to clean or replace.

[0016] 2. In this utility model, the worm is rotated by turning the handle. The worm wheel is fixed to the semi-cylinder, so the worm drives the slider to slide through the sleeve. Under the action of the semi-circular plate, the slider slides forward along the outer wall of the semi-circular plate, thereby adjusting the angle of the housing and improving the user experience.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1-Figure 3 This utility model provides an embodiment of a wall-mounted electric water heater shell, including a shell 1. A groove 2 is formed on the inner wall of the shell 1, and a protective pad 3 is provided on the outer wall of the shell 1. A hollow block 4 is fixedly connected inside the protective pad 3, and a push rod 5 is slidably connected inside the hollow block 4. A connecting plate 22 is fixedly connected to the upper surface of the push rod 5, and a first inclined block 6 is fixedly connected to the upper surface of the connecting plate 22. A second inclined block 7 is slidably connected to the upper surface of the first inclined block 6, and a third inclined block 8 is fixedly connected to the right outer wall of the second inclined block 7. The front outer wall of the third inclined block 8 is fixedly connected to the third inclined block 8. A telescopic rod 9 is fixedly connected, and a support block 11 is fixedly connected to the middle outer wall of the telescopic rod 9. A spring 10 is fixedly connected to the rear outer wall of the support block 11. The other end of the spring 10 is fixedly connected to the front outer wall of the inclined block 3 8. The rear outer wall of the inclined block 3 8 is slidably connected to the inner wall of the slot 2. A support assembly is provided on the inner wall of the wall 21. The support assembly is used to support the shell 1. The support assembly includes a fixing frame 20. The rear outer wall of the fixing frame 20 is fixedly connected to the inner wall of the wall 21. A semi-circular plate 17 is fixedly connected to the front outer wall of the fixing frame 20.

[0025] Specifically, when it is necessary to remove the protective pad 3, by pushing the push rod 5, the connecting plate 22 and the first inclined block 6 move upward. The inclined surface of the first inclined block 6 pushes the second inclined block 7 to slide forward, which in turn drives the third inclined block 8 to slide forward out of the inner wall of the slot 2. This removes the restriction on the hollow block 4 and achieves the effect of quickly removing the protective pad 3. The sliding of the second inclined block 7 by the inner wall of the support block 11 achieves the effect of range restriction, and the sliding of the push rod 5 by the interior of the hollow block 4 achieves the effect of offset restriction.

[0026] Reference Figure 2 and Figure 3The outer wall of the inclined block 3 8 is set on the inner wall of the shell 1. The right outer wall of the inclined block 2 7 is slidably connected to the outer wall of the support block 11. The outer wall of the inclined block 3 8 is slidably connected to the inner wall of the hollow block 4. The outer wall of the inclined block 3 8 is slidably connected to the inner wall of the support block 11. The outer wall of the support block 11 is fixedly connected to the inner wall of the hollow block 4.

[0027] Specifically, the offset restriction effect is achieved by the sliding of the hollow block 4 and the support block 11 onto the inclined block 7, and the offset restriction effect is achieved by the sliding of the inner wall of the support block 11 onto the inclined block 8.

[0028] Reference Figure 1 and Figure 4 A slider 12 is slidably connected to the outer wall of the semicircular plate 17. The upper surface of the slider 12 is fixedly connected to the lower surface of the housing 1. A handle 13 is rotatably connected inside the slider 12. A worm 14 is fixedly connected to the rear outer wall of the handle 13. A sleeve 15 is rotatably connected to both ends of the worm 14. The outer wall of the sleeve 15 is fixedly connected to the inner wall of the slider 12. A worm wheel 19 is meshed with the outer wall of the worm 14. A semi-cylinder 18 is fixedly connected inside the worm wheel 19. Both ends of the semi-cylinder 18 are fixedly connected to the outer wall of the semicircular plate 17. A limit block 16 is fixedly connected to the inner wall of the slider 12. The outer wall of the limit block 16 is slidably connected to the inner wall of the semicircular plate 17.

[0029] Specifically, rotating the handle 13 drives the worm gear 14 to rotate. When the worm gear 14 rotates, it is fixed to the semi-cylinder 18 through the worm wheel 19, causing the worm gear 14 to drive the slider 12 to slide backward through the sleeve 15. Under the action of the outer wall of the semi-circular plate 17, the slider 12 slides backward along the outer wall of the semi-circular plate 17, thereby achieving the effect of angle adjustment of the slider 12. The shape of the lower part of the limiting block 16 is larger than the inner wall of the semi-circular plate 17, which achieves the effect of assisting the slider 12 to slide and limiting the range. When the slider 12 is not in use, the worm gear 14 and the worm wheel 19 achieve a self-locking effect.

[0030] Working principle: When using the housing, the hollow block 4 is slid towards the inner wall of the housing 1 by holding the protective pad 3. Under the action of the inclined surface of the inclined block 3 8, the inclined block 3 8 is pushed forward, compressing the spring 10. The hollow block 4 smoothly fits against the inner wall of the housing 1. When the inclined block 3 8 slides to the inner wall of the slot 2, the elastic force of the spring 10 pushes the inclined block 3 8 backward, causing the outer wall of the inclined block 3 8 to slide into the inner wall of the slot 2 and lock the hollow block 4, achieving the effect of quickly fixing the protective pad 3. The protective pad 3 is fixed to the sharp edge of the housing 1, achieving the effect of preventing accidental injury. When it is necessary to adjust the tilt of the housing 1, the worm gear 14 is rotated by the handle 13. Under the action of the sleeve 15, the rotation of the worm gear 14 is supported, and the worm wheel 19 is used to adjust the tilt. The fixing of the semi-cylinder 18 causes the worm gear 14 to rotate, driving the lower outer wall of the slider 12 to slide forward along the outer wall of the semi-circular plate 17. The outer wall of the limiting block 16 slides along the inner wall of the semi-circular plate 17, thus limiting the sliding of the slider 12 and adjusting the angle of the housing 1. The fixing bracket 20 supports the housing 1 without it contacting the wall 21. During use, the housing not only has a protective pad 3 to reduce the risk of injury to the user when touching or cleaning it, but also allows for the fixing and removal of the protective pad 3, making it easy for the user to clean or replace it. It also allows for the adjustment of the angle of the housing 1, making the control panel and display screen of the water heater easy to observe and operate, thus improving the user experience.
