[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1 , Figure 4 and Figure 5 The utility model provides an embodiment of a wall-mounted electric auxiliary heating type solar water heater, comprising an insulated water tank 1 and a collector 2, the bottom of the insulated water tank 1 is fixedly connected with a filter box 3, the bottom connecting part of the filter box 3 is fixedly connected with a water inlet pipe 5, the filter box 3 is slidably connected with a filter plate 4 inside, the filter box 3 is provided with a connecting groove 10 on both sides, the connecting groove 10 is rotatably connected with a telescopic rod 11, one end of the telescopic rod 11 is rotatably connected with a clamping block 13, the inner side wall of the connecting groove 10 is provided with a limiting groove 7, the limiting groove 7 is fixedly connected with a spring 8, the other end of the spring 8 is fixedly connected with a limiting block 9, one side of the limiting block 9 is fixedly connected with a push rod 12, the left and right sides of the filter plate 4 are provided with a clamping groove 14, and the outside of the collector 2 is provided with an angle adjustment component 6.

[0026] Specifically, the heated water can be kept warm by the insulated water tank 1, so that it is convenient to use at any time, which improves convenience. The insulated water tank 1 is connected with the filter box 3, and the tap water entering the insulated water tank 1 is filtered by the filter plate 4 inside the filter box 3, so that the scale generated after the water is heated is greatly reduced, and the scale adhering to the inside of the collector 2 is reduced, thereby ensuring the heating efficiency and extending the service life of the water heater. The push rods 12 on both sides of the filter box 3 can push the limit block 9 to slide inside the limit groove 7, thereby causing the spring 8 to contract, wherein the limit groove 7 limits the movement of the limit block 9 and the spring 8 to ensure smooth movement. At the same time, the limit block 9 drives one end of the telescopic rod 11 to move, thereby causing it to rotate and driving the card block 14 to move through the other end, so that the card block 13 is disengaged from the card slot 14. At this time, the filter plate 4 can be pulled out of the filter box 3, thereby realizing the replacement of the filter plate 4, which can extend the service life of the filter box 3 and facilitate maintenance.

[0027] Reference Figure 4 and Figure 5The angle adjustment component 6 includes a mounting frame 601, which is fixedly connected to the wall by screws. A slide groove 602 is provided on both sides of the mounting frame 601. A threaded rod 603 is rotatably connected inside the left slide groove 602, and a threaded sleeve 604 is threadedly connected to the outside of the threaded rod 603. A slide rod 605 is fixedly connected inside the right slide groove 602, and a slider 606 is slidably connected to the outside of the slide rod 605. The outsides of the threaded sleeve 604 and the slider 606 are rotatably connected to a support rod 607. A fixing frame 608 is rotatably connected to the top of the mounting frame 601. The outside of the threaded sleeve 604 and the outside of the slider 606 are slidably connected to the inner wall of the slide groove 602. One end of the support rod 607 is rotatably connected to the outside of the fixing frame 608. A handle is provided at one end of the threaded rod 603 fixedly passing through the top outer wall of the mounting frame 601.

[0028] Specifically, the installation frame 601 is fixed to the wall by screws, so that the collector 2 can be fixed. The sliding groove 602 can limit the sliding of the threaded sleeve 604 and the slider 606. The threaded sleeve 604 can slide in the sliding groove 602 by rotating the handle at one end of the threaded rod 603. At the same time, with the cooperation of the slider 606, the two support rods 607 are pushed to move, and then the fixed frame 608 is pushed to rotate, so as to adjust the inclination angle of the collector 2. The support rods 607 support the fixed frame 608, so that the sun can maintain direct radiation on the collector 2, thereby improving its absorption efficiency of solar energy and enhancing the heating effect. The fixed frame 608 can fix the collector 2 to prevent it from slipping after installation.

[0029] Reference Figure 1 , Figure 3 and Figure 5 A controller 17 is provided on the outer wall of the insulated water tank 1, and the bottom connecting part of the insulated water tank 1 is connected to the collector 2 through two circulating water pipes. A plurality of heating rods 15 are fixedly connected inside the insulated water tank 1, and a fixing frame 16 is provided on the top and bottom ends of the outer walls of the plurality of heating rods 15. The outside of the spring 8 and the outside of the limit block 9 are both slidably connected to the inside of the limit groove 7, and the outside of the limit block 9 is rotatably connected to one end of the telescopic rod 11. The cross-section of the clamping block 13 is set to a square, and the clamping block 13 is slidably connected to the outside and the inside of the clamping groove 14.

[0030] Specifically, the controller 17 can start the heating rod 15 in the insulated water tank 1 to heat the water, which has the effect of electric auxiliary heating. It can ensure that the use of solar energy is not affected on rainy days, and the flexibility of the use of the solar water heater is improved. The insulated water tank 1 and the collector 2 are connected through a circulating water pipe, so that the water can be heated and circulated. The fixing frame 16 can limit the heating rod 15 so that it will not loosen. The limiting groove 7 can limit the sliding of the spring 8 and the limiting block 9 so that they slide on the same horizontal line to ensure stable operation. The filter plate 4 is fixed by the plug-in cooperation of the clamping block 13 and the clamping slot 14, which is convenient for disassembly and replacement, thereby extending the service life of the device.

[0031] Working principle: When using this solar water heater, water enters the filter box 3 through the water inlet pipe 5, enters the insulated water tank 1 after being filtered by the filter plate 4, and then enters the insulated water tank 1 through the two connecting water pipes at the bottom. After the water is heated, it returns to the insulated water tank 1 for insulation. The filter plate 4 can be disassembled, and the push rods 12 on both sides of the filter box 3 are pressed to push the limit block 9 to slide inside the limit groove 7, thereby causing the spring 8 to contract. At the same time, the limit block 9 drives one end of the telescopic rod 11 to move, thereby causing it to rotate and drive the clamping block 14 to move through the other end, so that the clamping block 13 is disengaged from the clamping groove 14. At this time, the filter plate 4 can be pulled out of the filter box 3, and the water is filtered through the filter plate 4, so that the scale generated after the water is heated is greatly reduced, thereby preventing the adhesion of the scale from affecting the heating effect. At the same time, the filter plate 4 can be easily disassembled and replaced through the clamping method, thereby extending the service life of the water heater. The controller 17 can start the heating rod 15 in the thermal insulation water tank 1 to heat the water, thereby ensuring that the use of solar energy is not affected on rainy days.

[0032] If the inclination angle of the collector 2 needs to be adjusted, it can be achieved through the angle adjustment component 6, specifically, the handle at one end of the threaded rod 603 is rotated to make the threaded sleeve 604 slide inside the slide groove 602, thereby pushing a support rod 607 to move. At the same time, the slider 606 slides along the direction of the slide rod 605, and also pushes a support rod 607 to move, thereby changing the inclination angle of the fixed frame 608, which can change the inclination angle of the collector 2, thereby improving its absorption efficiency of solar energy and enhancing the heating effect.
