Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
The first embodiment is as follows:
referring to fig. 1-5, in this embodiment, the electric water heater includes an electric water heater body 1, and an outlet pipe 3, a magnesium rod 2 and a sewage draining outlet 4 installed on the electric water heater body 1, a water outlet channel 19 is installed at a lower end of the electric water heater body 1, a water outlet pipe 20 communicated with the water outlet channel 19 is installed on a side wall of the water outlet pipe 3, a ball valve 10 is installed at a connection position of the water outlet pipe 20 and the water outlet pipe 3, a device groove 16 communicated with the water outlet channel 19 is installed in the side wall of the electric water heater body 1, a rotating rod 18 is rotatably connected to an inner wall of the device groove 16, an impeller 17 is fixedly connected to an outer side wall of the rotating rod 18, a lower end of the impeller 17 is located in the water outlet channel 19, a device cavity 25 is installed at a rear side of the device groove 16, one end of the rotating rod 18 extends into the device cavity 25 and is fixedly provided with a cam 24, a cavity 13 is installed above the device cavity 25, a resisting rod 23 is slidably connected to an inner bottom of the cavity 13, a lower end of the resisting rod 23 extends into the device cavity 25 and is abutted against an outer side wall of the cam 24 through the pulley, the upper end of the resisting rod 23 is provided with a piston 14, the resisting rod 23 is sleeved with a first spring 15, the inner wall of the cavity 13 is connected with an air suction pipe 12 communicated with the outer side wall of the electric water heater body 1, a one-way valve is arranged in the air suction pipe 12, the inner walls opposite to the electric water heater body 1 are provided with sliding grooves 9, and a cleaning mechanism is arranged in the sliding grooves 9.
In the invention, the cleaning mechanism comprises a strip-shaped folding airbag 6 which is connected in a sliding groove 9 in a sliding way, the strip-shaped folding airbag 6 is communicated with a cavity 13 through an air outlet pipe 7, a one-way valve is arranged in the air outlet pipe 7, an air pipe 5 which is communicated with the outside of the electric water heater body 1 in a sealing way is arranged on the strip-shaped folding airbag 6, two ends in the strip-shaped folding airbag 6 are connected through a second spring 22, a connecting rod 8 is fixed on the side wall of the strip-shaped folding airbag 6, an arc-shaped scraper 11 is fixed at the tail end of the connecting rod 8, and the one-way valve in the air outlet pipe 7 ensures that gas can only be discharged from the air outlet pipe 7 but can not be sucked. The shape of the arc-shaped scraper 11 is the same as that of the inner wall of the electric water heater body 1, the rubber eraser 21 is fixed on the outer side wall of the arc-shaped scraper 11, the rubber eraser 21 is in contact with the inner wall of the electric water heater body 1, and the rubber eraser 21 can increase the friction force with the inner wall of the electric water heater body 1, so that the cleaning effect is improved. The pipe diameter of the air outlet pipe 7 is far larger than that of the air vent pipe 5, so that the air output of the air outlet pipe 7 is larger than the air output of the air vent pipe 5, and the strip-shaped folding air bag 6 can be normally unfolded.
In the invention, when the electric water heater body 1 needs to be cleaned, only water needs to be kept, the ball valve 10 is rotated to enable water in the electric water heater body 1 to be discharged into the water discharge pipe 20 through the water outlet pipe 3 and then flow into the water outlet channel 19, the impeller 17 is driven to rotate by the high water flow speed, the rotating rod 18 rotates along with the rotating rod, the rotating rod 18 drives the cam 24 to rotate, the abutting rod 23 is always abutted against the cam 24 by the first spring 15, so that the abutting rod 23 is driven to slide up and down in a reciprocating manner, the abutting rod 23 drives the piston 14 to slide in the cavity 13, gas is filled into the strip-shaped folding air bag 6 through the air outlet pipe 7 in the upward moving process, gas is sucked through the air suction pipe 12 in the downward moving process and is inflated in a reciprocating manner, the strip-shaped folding air bag 6 expands and stretches out, the arc-shaped scraper 11 is driven by the connecting rod 8 to clean the inner wall of the electric water heater body 1, adhered dirt is scraped, and finally the dirt is discharged by opening the sewage discharge port 4, close drain pipe 20 after the blowdown is finished, reset through second spring 22 to the folding gasbag of strip 6 this moment, the inside gas of the folding gasbag of strip 6 slowly discharges through air vent 5, and it is worth noting that because the pipe diameter of outlet duct 7 is greater than the pipe diameter of breather pipe 5, the air output of outlet duct 7 is greater than the displacement of breather pipe 5 for the folding gasbag of strip 6 can normally stretch out.
Example two:
referring to fig. 6, in this embodiment, a space of the cavity 13 below the piston 14 is a gas storage cavity 26, an annular folding airbag 28 is fixed around the bottom end of the magnesium rod 2, a plurality of brush heads 27 contacting with the outer side wall of the magnesium rod 2 are uniformly distributed on the inner wall of the annular folding airbag 28, and the gas storage cavity 26 is communicated with the annular folding airbag 28 through a connecting pipe 29.
After the electric water heater body 1 works for a period of time, a large amount of dirt can be attached to the inner wall, more dirt can be adsorbed on the magnesium rod 2, if the cleaning is not timely carried out, the normal decomposition of the magnesium rod 2 can be influenced, the cation content in water is reduced, and the water can erode the inner container more easily. When the magnesium rod 2 needs to be cleaned, when the piston 14 moves up and down in the cavity 13, the gas in the gas storage cavity 26 is squeezed into the annular folding airbag 28 through the connecting pipe 29 in the downward moving process, the annular folding airbag 28 expands and rises to wrap the magnesium rod 2, the surface of the magnesium rod 2 is scrubbed through the plurality of brush heads 27, dirt is brushed down, the gas in the annular folding airbag 28 is sucked away in the upward moving process of the piston 14, the annular folding airbag 28 contracts to scrub downwards, and therefore the magnesium rod 2 is scrubbed in a reciprocating mode, and the cleaning effect is good.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
