Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0026] As Figure 1-4As shown in the figure, this embodiment proposes a ball valve for an electric water heater, including a valve body 1. At the rear end of the valve body 1, there are two water inlet components 5 for guiding water flow into the interior of the valve body 1. Above the two water inlet components 5, there is an operation component 2 for controlling the valve body 1. At the lower end of the operation component 2, there are two lifting components 3 for controlling the mixing of cold and hot water.

At the front end of the two water inlet components 5, there is a mixing component 6 for guiding the water body to flow out of the valve body 1 and mix. At the front end of the valve body 1, there are two control panels 7 fixedly connected. The operation component 2 includes an operation cavity 201 opened at the top end inside the valve body 1. Inside the operation component 2, there is a first bevel gear 202. The inner wall of the first bevel gear 202 is fixedly connected with an operation rod 203. The front end of the operation rod 203 penetrates through the front outer wall of the valve body 1 and is rotatably connected thereto. The front end of the operation rod 203 is fixedly connected with a rotating wheel 204. The operation component 2 further includes a second bevel gear 205 meshingly connected to the outer wall of one side of the first bevel gear 202. The inner wall at the center of the second bevel gear 205 is fixedly connected with a first rotating rod 206. Below the second bevel gear 205, there is a first spur gear 207. The inner wall of the first spur gear 207 is fixedly connected with the first rotating rod 206. The bottom end of the first rotating rod 206 is rotatably connected to the bottom inner wall of the operation cavity 201 through a bushing. The operation component 2 further includes second spur gears 208 meshingly connected to the outer walls on the left and right sides of the first spur gear 207. The inner walls at the centers of the two second spur gears 208 are fixedly connected with second rotating rods 209. The top ends of the two second rotating rods 209 are rotatably connected to the top inner wall of the operation cavity 201 through bushings. The lifting component 3 includes an electric telescopic rod 302 fixedly connected to the bottom end of each second rotating rod 209. An lifting cavity 301 is arranged outside the electric telescopic rod 302. The output end of the electric telescopic rod 302 is fixedly connected with a sliding sleeve 303. When the rotating wheel 204 rotates, the operation rod 203 is driven to rotate by the rotating wheel 204, so that the operation rod 203 drives the second bevel gear 205 to mesh and rotate, so that the second bevel gear 205 drives the first rotating rod 206 to rotate. The first spur gear 207 is driven to rotate by the first rotating rod 206. The second spur gears 208 are driven to mesh and rotate by the first spur gear 207. At the same time, the second spur gears 208 on both sides of the first spur gear 207 drive the ball 402 to control the hot water pipe and the cold water pipe, so that cold and hot water enter and exit the valve body 1 simultaneously and are mixed.

[0027] As Figure 1-6As shown, the lifting assembly 3 further includes a plurality of engaging grooves 304 penetrating through the outer wall of the bottom end of the sliding sleeve 303.

A plurality of engaging blocks 306 are fixedly connected to the bottom end of the fixed disk 305. The plurality of engaging blocks 306 are annularly arrayed at the bottom end of the fixed disk 305. The number of the engaging blocks 306 is the same as that of the engaging grooves 304 and they correspond to each other one by one. The ball valve assembly 4 includes a connecting rod 401 fixedly connected to the center of the bottom end of the fixed disk 305. A ball 402 is fixedly connected to the bottom end of the connecting rod 401. A spherical closing cavity 403 is formed in the inner wall of the bottom end of the valve body 1. The spherical closing cavity 403 is rotatably connected to the outer wall of the ball 402. The inner wall of the bottom end of the sliding sleeve 303 is rotatably connected to the outer wall of the connecting rod 401. When the user needs to use only the water flow on the left side, the left control panel 7 is controlled, so that the output end of the left electric telescopic rod 302 moves upward, so that the output end of the electric telescopic rod 302 drives the left sliding sleeve 303 to move upward, so that the engaging groove 304 at the bottom end of the left sliding sleeve 303 moves upward to engage with the engaging block 306, so that the engaging block 306 is fixed to the sliding sleeve 303, and further the sliding sleeve 303 is fixed to the fixed disk 305. At this time, by rotating the runner 204, the second spur gears 208 on both sides of the first spur gear 207 rotate, so that the two second spur gears 208 drive the electric telescopic rod 302 to rotate. The sliding sleeve 303 is driven to rotate by the two electric telescopic rods 302. At the same time, the left sliding sleeve 303 is fixed to the fixed disk 305. Therefore, the left sliding sleeve 303 can drive the left fixed disk 305 to rotate. At the same time, the left fixed disk 305 drives the left connecting rod 401 to rotate. At the same time, the left connecting rod 401 drives the ball 402 to rotate, so that the inside of the left spherical closing cavity 403 is in a communicating state, so that the water flow on the left side flows out. At the same time, when the right sliding sleeve 303 rotates, the right fixed disk 305 is inside the sliding sleeve 303 and will not rotate with the rotation of the sliding sleeve 303. Therefore, it is in a closed state, so that the right spherical closing cavity 403 is in a closed state.

The rear ends of both water outlet cavities 601 communicate with the inside of the spherical closing cavity 403, and a fusion box 602 is communicated with the front ends of both water outlet cavities 601. The outer wall at the rear end of the fusion box 602 is fixedly connected to the outer wall of the valve body 1, and a water outlet pipe 603 is communicated with the front end of the fusion box 602. When both water outlet cavities 601 on both sides are in a communicating state, the water flows on both sides enter the fusion box 602 through the water outlet cavities 601 for fusion, so that the fused water is in a warm state. At the same time, the water outlet pipe 603 is opened, so that the warm water flows out through the water outlet pipe 603.

[0029] In this embodiment, when in use, the two water inlet pipes 501 at the rear end of the valve body 1 are respectively connected to the cold water pipe and the hot water pipe. At the same time, the two electric telescopic rods 302 are controlled by the two control panels 7, so that the output ends of the two electric telescopic rods 302 move upward simultaneously. At the same time, the output ends of the electric telescopic rods 302 drive the sliding sleeves 303 to move upward, and the engaging grooves 304 are driven to move upward by the two sliding sleeves 303 and are engaged with the engaging blocks 306 at the bottom end of the fixed disk 305, so that the bottom end of the fixed disk 305 is attached to the inner wall of the bottom end of the sliding sleeve 303, and the fixed disk 305 is fixed to the sliding sleeve 303. At this time, manually rotate the rotating wheel 204, drive the operating rod 203 to rotate through the rotating wheel 204, drive the first bevel gear 202 to rotate through the operating rod 203, drive the second bevel gear 205 to engage and rotate through the first bevel gear 202, so that the second bevel gear 205 drives the first rotating rod 206 to rotate, drive the first spur gear 207 to rotate through the first rotating rod 206, drive the second spur gears 208 on both sides of the first spur gear 207 to engage and rotate simultaneously through the first spur gear 207, so that the second spur gears 208 on both sides of the first spur gear 207 rotate simultaneously, drive the second rotating rods 209 to rotate through the two first spur gears 207 simultaneously, drive the electric telescopic rods 302 to rotate through the two second rotating rods 209 simultaneously, drive the sliding sleeves 303 to rotate through the two electric telescopic rods 302 simultaneously, drive the fixed disks 305 to rotate through the two sliding sleeves 303 simultaneously, drive the connecting rods 401 to rotate through the two fixed disks 305 simultaneously, drive the spheres 402 to rotate through the two connecting rods 401 simultaneously, so that the inside of the spherical closing cavities 403 outside the two spheres 402 is in a connected rotation state, so that the water flows in the cold water pipe and the hot water pipe enter the two water inlet cavities 502 through the two water inlet pipes 501 simultaneously, enter the two water outlet cavities 601 through the two spherical closing cavities 403 simultaneously, and guide the cold water and the hot water to enter the fusion box 602 simultaneously for fusion.
