DETAILED DESCRIPTION

[0016] See also Figure 1-Figure 4The utility model provides the following technical solutions: including a variable frequency electromagnetic intelligent heating machine 1, a water inlet pipe 11 and a drain pipe 12, the top of the variable frequency electromagnetic intelligent heating machine 1 is fixedly connected with a filter box 2, the filter box 2 is provided with a water inlet chamber 21 and a lower water tank 22, the water inlet pipe 11 is connected with the inner space of the water inlet chamber 21, the lower water tank 22 is located below the water inlet chamber 21, the inner wall of the filter box 2 is slidably connected with a slide plate 3, the slide plate 3 is provided with two water holes 31, and the two water holes 31 are provided with water holes 31. The inner wall of each of the two water holes 31 is hinged with an interception mesh plate 32, and a torsion spring 321 is arranged between the interception mesh plate 32 and the corresponding water through hole 31. The torsion spring 321 drives the interception mesh plate 32 to flip downward, and the two water through holes 31 slide alternately to the corresponding positions of the lower water tank 22. Two impurity discharge grooves 23 are arranged in the filter box 2, and the two interception mesh plates 32 are respectively slidably connected to the inner wall of the corresponding impurity discharge groove 23. The inner wall of the two impurity discharge grooves 23 is provided with four ball rods 4, and the ball rods 4 are in contact with the bottom end of the corresponding interception mesh plate 32.

[0017] In this implementation scheme: the variable frequency electromagnetic intelligent heating machine 1 supports the various components of the device, the water inlet pipe 11 is used to transport water for the device, and the heated water is discharged through the drain pipe 12 for use. The water transported by the water inlet pipe 11 first enters the water inlet chamber 21 before entering the variable frequency electromagnetic intelligent heating machine 1. The filter box 2 supports the internal components and provides external protection. The water in the water inlet chamber 21 is discharged downward into the lower water tank 22, and the lower water tank 22 transfers the filtered water into the variable frequency electromagnetic intelligent heating machine 1 for heating treatment. The sliding plate 3 blocks the passage of the lower water tank 22. The sliding plate 3 is transferred and slid by the motor and the screw drive inside the filter box 2. The sliding plate 3 opens the passage of the lower water tank 22 through two water holes 31. The interception mesh plate 32 filters the water source flowing in the water hole 31, so as to timely intercept and clean the impurities and the fallen scale in the water, and prevent the impurities and scale from entering the variable frequency electromagnetic intelligent heating machine 1 to block the pipeline and affect the working performance of the variable frequency electromagnetic intelligent heating machine 1. The interception mesh plate 32 is in a horizontal position under the influence of the inner wall of the filter box 2, and the impurity discharge groove 23 is used to discharge the impurities and scale intercepted by the interception mesh plate 32. When one of the interception mesh plates 32 intercepts too much impurities and scale and affects the water flow and needs to be cleaned, the slide plate 3 is controlled to move horizontally, and the slide plate 3 drives the two interception mesh plates 32 to adjust their positions, so that the other water hole 31 and the interception mesh plate 32 can slide to the lower water tank 22. The interception and filtration work continues at the position. At this time, the interception mesh plate 32 that needs to be cleaned reaches the corresponding impurity discharge groove 23, and the torsion spring 321 drives the interception mesh plate 32 to flip downward. At this time, the impurity discharge groove 23 makes way for the interception mesh plate 32, so that the interception mesh plate 32 is no longer limited by the filter box 2, and the interception mesh plate 32 limits the garbage and impurities on the water through hole 31 at the bottom, so that the intercepted impurities and scale can be temporarily stored in the space of the water through hole 31. As the torsion spring 321 drives the interception mesh plate 32 to flip downward, the impurities and scale temporarily stored on the interception mesh plate 32 and in the water through hole 31 can slide along the interception mesh plate 32 to the inside of the impurity discharge groove 23. At the same time, the interception mesh plate 32 contacts and collides with a number of corresponding ball rods 4, and the ball rods 4 collide with the attached The impurities and scale on the intercepting mesh plate 32 are impacted and vibrated off, thereby facilitating the shedding of the impurities and scale, and further realizing the cleaning of the intercepting mesh plate 32. The impurity discharge groove 23 is connected to the external space, and the inner wall of the bottom end of the impurity discharge groove 23 is arranged to be inclined, so that the impurities and scale falling into the impurity discharge groove 23 can be discharged to the outside of the device along the impurity discharge groove 23, without manual shutdown for cleaning, which greatly alleviates the labor cost, is simple and convenient, and will not compress the normal working time of the variable frequency electromagnetic intelligent heating machine 1 to affect the heating demand, and the water source that has been heated inside the variable frequency electromagnetic intelligent heating machine 1 can continue to be discharged to avoid heat loss, which meets the social needs of energy conservation and emission reduction; it should be noted that, if Figure 2As shown, when the slide board 3 is controlled to move laterally, in order to facilitate the interception mesh plate 32 located at the debris removal groove 23 to restore the horizontal state, the right side of the interception mesh plate 32 on the left is hinged to the water hole 31, and the left side of the interception mesh plate 32 on the right is hinged to the water hole 31, so that when the slide board 3 is controlled to move laterally, the interception mesh plate 32 located at the debris removal groove 23 can better restore the horizontal state.

[0018] Two drain grooves 24 are provided in the filter box 2, and both drain grooves 24 are connected to the internal space of the lower water tank 22, and the inner walls of the two drain grooves 24 are installed with one-way valves 241; when the sliding plate 3 drives the water through hole 31 and the intercepting mesh plate 32 to move toward the direction of the impurity discharge groove 23, the water through hole 31 and the intercepting mesh plate 32 will first reach the top opening of the drain groove 24, and at this time, the water through hole 31 is completely separated from the lower water tank 22, thereby preventing the water source flowing inside the lower water tank 22 from entering the water through hole 31 again, and then the water source retained in the water through hole 31 is released through the drain groove 24, and then the intercepting mesh plate 32 drives the intercepted impurities and scale to reach the impurity discharge groove 23 for discharge, reducing the resource waste problem caused by the discharge of impurities in the water source retained in the water through hole 31, and the one-way valve 241 intercepts the water source entering the drain groove 24 from the lower water tank 22 to prevent the water source in the lower water tank 22 from leaking.

[0019] Two fixed plates 25 are fixedly connected to the inner wall of the lower water tank 22, and telescopic plates 26 are installed in the two fixed plates 25. The output ends of the two telescopic plates 26 are in contact with the inner wall of the lower water tank 22; there is an expansion space under the lower water tank 22, and the two fixed plates 25 support the corresponding telescopic plates 26. The telescopic plates 26 and the fixed plates 25 form a blockade for the expansion space of the lower water tank 22. The water source flowing from top to bottom in the lower water tank 22 first enters the expansion space under the lower water tank 22. When the water level in the expansion space under the lower water tank 22 is filled When the two water holes 31 and the two intercepting mesh plates 32 are used interchangeably, the sliding plate 3 blocks the lower water tank 22 during the sliding process, so that the water inside the water inlet chamber 21 cannot flow into the lower water tank 22 temporarily, and the two telescopic plates 26 are controlled to shrink toward the inside of the fixed plate 25, so that the gap under the fixed plate 25 is no longer blocked. At this time, the water stored in the expanded space under the lower water tank 22 is discharged, thereby avoiding dry burning caused by lack of water inside the variable frequency electromagnetic intelligent heating machine 1.

[0020] Two touch-pressure switches 261 corresponding to the telescopic plates 26 are installed on the inner wall of the filter box 2, and the sliding board 3 is in contact with one end of the two touch-pressure switches 261; the two touch-pressure switches 261 control the two telescopic plates 26, and when the sliding board 3 squeezes one of the touch-pressure switches 261, the touch-pressure switch 261 controls the telescopic plate 26 to extend to intercept the water source in the expanded space below the lower water tank 22; when the sliding board 3 slides, the two touch-pressure switches 261 are not squeezed by the sliding board 3, and at this time, the two telescopic plates 26 shrink at the same time to release the water source.

[0021] The side wall of the ball rod 4 is slidably connected to a limit tube 41, and the limit tube 41 is fixedly connected to the inner wall of the corresponding impurity removal groove 23. A spring 42 is fixedly connected between the ball rod 4 and the impurity removal groove 23; the limit tube 41 supports the ball rod 4, and the spring 42 elastically pushes the ball rod 4. When the intercepting mesh plate 32 collides with the ball rod 4, the ball rod 4 can use the spring 42 to produce a rebound effect, so that the intercepting mesh plate 32 can be impacted multiple times, thereby improving the ability to separate impurities and scale.

[0022] The working principle and use process of the utility model are as follows: when the device is in use, the water inlet pipe 11 transports water into the water inlet chamber 21, and the water inlet chamber 21 transfers the water into the lower sink 22. The sliding plate 3 intercepts and filters impurities and scale in the water source through the water through hole 31 and the interception mesh plate 32. The filtered water fills the expansion space below the lower sink 22 and then is discharged into the variable frequency electromagnetic intelligent heating machine 1 through the lower sink 22 for heating treatment. When one of the interception mesh plates 32 intercepts too much impurities and scale and affects the water flow and needs to be cleaned, the sliding plate 3 is controlled to move horizontally, and the sliding plate 3 drives the two interception mesh plates 32 to adjust their positions, so that the other water through hole 31 and the interception mesh plate 32 can slide to the position of the lower sink 22 to continue intercepting and filtering. The water through hole 31 and the interception mesh plate 32 will first reach the top opening of the drain trough 24, and then the water retained in the water through hole 31 is released through the drain trough 24, and then the interception mesh plate 32 drives the intercepted The impurities and scale are discharged into the drainage groove 23, which reduces the resource waste problem caused by the discharge of impurities in the water source retained in the water hole 31. The interception mesh plate 32 reaches the corresponding drainage groove 23, and the torsion spring 321 drives the interception mesh plate 32 to flip downward, and the interception mesh plate 32 collides with the ball rod 4. The ball rod 4 can use the spring 42 to produce a rebound effect, so that the interception mesh plate 32 can be impacted multiple times, thereby improving the ability of impurities and scale to be separated, and thus the interception mesh plate 32 is cleaned. The impurities and scale that fall into the drainage groove 23 can be discharged to the outside of the device along the drainage groove 23. There is no need to manually stop the machine for cleaning, which greatly alleviates the labor expenditure. It is simple and convenient, and the normal working time of the variable frequency electromagnetic intelligent heating machine 1 will not be compressed to affect the heating demand. In addition, the water source that has been heated inside the variable frequency electromagnetic intelligent heating machine 1 can continue to be discharged to avoid heat loss, which meets the social needs of energy conservation and emission reduction.
