The present invention includes an insulation tank, a device body is arranged inside the insulation tank, a circulation pipe is arranged between the outer wall of the device body and the inner wall of the insulation tank, a support frame is arranged on the outer wall of the insulation tank, and a heating barrel is arranged on the left side of the support frame.

Description

Technical Field

[0001] The invention relates to the technical field of environmental protection equipment, in particular to a low-temperature vacuum evaporator capable of rapid preheating. Background Art

[0002] The vacuum evaporator can make the material liquid flow in a film-like manner along the heating tube wall to transfer heat and evaporate. It has the same effect as the falling film evaporator, that is, after the material moves in a film-like manner, the heating time of the material can be greatly reduced. At the same time, the difference between the negative pressure caused by the internal space of the evaporator and the pressure at the bottom of the evaporator is used as the power to make the solution circulate automatically, thereby increasing the evaporation rate.

[0003] Patent announcement number CN221412251U discloses a low-temperature vacuum evaporator that can be preheated quickly, which includes a base and a heating box, a fixing frame is arranged on the top of the base, and the side walls of the two fixing frames are provided with insulation tanks, and the device body is arranged in the insulation tank, the heating box is arranged on the top of the base, and the side walls of the inner cavity of the heating box are provided with heaters, and the top of the heating box is provided with a water pump, and a connecting pipe is embedded in the heating box, and one end of the connecting pipe is connected to the water pump. This patent facilitates the rapid preheating of the device when the low-temperature vacuum evaporator is used in seasons with lower temperatures, so that the evaporated liquid in the device can be quickly heated, the heating effect is better, the efficiency is higher, heat loss is reduced, energy consumption is reduced, and the normal use of the equipment is beneficial.

[0004] However, the device still has some shortcomings: the device can quickly preheat the liquid inside the device body and reduce energy consumption, but during the preheating process, when heating the water source, the water source is always in a static heating state, which can easily cause the water source to be heated unevenly during the heating process. When preheating the liquid inside the device body, it is easy for the uneven water temperature to cause differences in the preheating temperature of the liquid in different parts of the device body, affecting the overall preheating uniformity. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides a low-temperature vacuum evaporator that can be quickly preheated, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a low-temperature vacuum evaporator capable of rapid preheating, comprising an insulation tank, a device body is arranged inside the insulation tank, a circulation pipe is arranged between the outer wall of the device body and the inner wall of the insulation tank, a support frame is arranged on the outer wall of the insulation tank, a heating barrel is arranged on the left side of the support frame, a water pump is arranged on the top of the heating barrel, a water delivery pipe is arranged between the top of the water pump and the top of the circulation pipe, and a reflux pipe is arranged between the right side of the heating barrel and the bottom of the circulation pipe;

[0007] A heat mixing device is provided inside the heating barrel, a converging device is provided above the heat mixing device, and a scale shielding device is provided outside the converging device;

[0008] The heat mixing device includes an electric rotating rod, the bottom of which is rotatably installed at the center of the bottom of the inner wall of the heating barrel, a plurality of stirring plates are equidistantly and fixedly installed on the outer wall of the bottom end of the electric rotating rod, a collar is penetrated through and movably installed on the outer wall of the reciprocating spiral groove of the electric rotating rod, a plurality of cross plates are equidistantly and fixedly installed on the outer wall of the collar, a heating component is fixedly installed on the end of the cross plate away from the collar, a water pump is penetrated through and fixedly installed on the end of the cross plate close to the collar, a spiral hose is fixedly installed between the top of the water pump and the bottom of the water pump, an I-beam is rotatably installed inside the U-shaped groove of the stirring plate, a plurality of arc panels are equidistantly and fixedly installed on the outer wall of the I-beam near the center end of the stirring plate, and a U-shaped mesh plate is slidably installed on the outer wall of the stirring plate through a spring.

[0009] According to the above technical solution, a reciprocating spiral groove is provided on the outer wall at the top of the electric rotating rod, and a U-shaped groove is provided on the bottom of the stirring plates. The outer wall of the heating component is slidably connected to the inner wall of the heating barrel, and the outer walls at both ends of the I-shaped column are in contact with the bottom of the inner wall of the heating barrel. The arc surface of the bottom of the U-shaped mesh plate is located on the movement trajectory of the arc plate. The electric rotating rod is started, and the stirring plate is driven to revolve when the electric rotating rod rotates along the bottom of the inner wall of the heating barrel, and the stirring plate revolves and stirs the water source inside the heating barrel. At the same time, the electric rotating rod limits the built-in block of the ring through the reciprocating spiral groove on its own outer wall, so that the ring can slide back and forth upward and reset along the outer wall of the electric rotating rod, and the ring drives the horizontal plate to move synchronously, and the horizontal plate drives the heating component to move synchronously along the inner wall of the heating barrel. At the same time, the horizontal plate drives The water pumping gun moves synchronously, and the water pumping gun drives the spiral hose to move synchronously. The spiral hose supplies water to the inside of the water pump through the water pumping gun. The water pump delivers hot water to the inside of the circulation pipe through the water pipe. The hot water will emit heat when circulating inside the circulation pipe. At the same time, the hot steam quickly fills the cavity between the insulation tank and the device body, thereby realizing rapid preheating of the liquid inside the device body; when the stirring plate revolves, it drives the I-beam column to move synchronously along the bottom of the inner wall of the heating barrel to generate friction. The I-beam column begins to rotate inside the stirring plate due to the friction. The I-beam column drives the arc panel to revolve. When the arc panel revolves, it breaks away from the resistance to the arc surface at the bottom of the U-shaped mesh plate. At this time, the U-shaped mesh plate moves downward due to the elastic force of the spring. When the arc panel resists again, the U-shaped mesh plate is reset, and this process repeats.

[0010] According to the above technical solution, the converging device includes a round rod, a spoiler frame, a cross bar, a flip plate and a guide arc block. The top of the round rod is rotatably installed at the top edge of the inner wall of the heating barrel, and several spoiler frames are fixedly installed on the outer wall of the top end of the round rod. Both ends of the cross bar are fixedly installed inside the spoiler frame. The flip plate passes through and is hinged on the outer wall of the cross bar. The guide arc block is fixedly installed on the outer wall of the flip plate close to the spoiler frame.

[0011] According to the above technical solution, the bottom of the round rod passes through and is threadedly connected to the inside of the end of the cross plate away from the collar, and a number of the spoiler frames are equidistantly distributed on the outer wall of the round rod. A torsion spring is arranged between the inside of the flip plate and the cross bar. The upward movement of the cross plate will drive the threaded round rod to generate a rotational force. The round rod rotates along the top of the inner wall of the heating barrel and drives the spoiler frame to revolve. The spoiler frame drives the cross bar to move synchronously when it revolves. When the cross bar drives the flip plate to revolve, the flip plate drives the guide arc block to move synchronously. When the guide arc block revolves, it unilaterally guides the water source contacted by its own arc surface. At this time, the flip plate generates a rotational force through the resistance generated between its own revolution and the water source, and the water source guided by the guide arc block. The flip plate starts to rotate along the outer wall of the cross bar, and then the flip plate is reset by the torsion spring.

[0012] According to the above technical solution, the convergence device also includes a cam, a sliding arc plate and a circular plate. The cam passes through and is fixedly installed on the outer wall of the top end of the round rod. The top of the sliding arc plate is slidably installed on the top of the inner wall of the heating barrel through a spring. The spiral hose is located on the arc motion trajectory of the sliding arc plate. The outer wall of the circular plate is fixedly installed on one end of the sliding arc plate close to the cam, and the outer wall of the circular plate is in contact with the cam. When the round rod rotates, it drives the cam to rotate. When the cam rotates, it will resist the outer wall of the circular plate. The circular plate generates a force moving toward the center of the heating barrel through the resistance of the cam. At this time, the circular plate pushes the sliding arc plate to slide synchronously along the inner wall of the heating barrel. When the cam is reset, the sliding arc plate will drive the circular plate to reset when it resets itself through the spring, and so on.

[0013] According to the above technical solution, the scale shielding device includes an L-shaped frame, a hollow flexible plate, an elastic strip and a protrusion plate. The L-shaped frame is fixedly installed on the outer wall of the sliding arc plate near the cam, the hollow flexible plate is fixedly installed on the outer wall of the L-shaped frame near the cam, the elastic strip is fixedly installed on the outer wall of the L-shaped frame near the circular plate, the top of the protrusion plate is fixedly installed on the top of the inner wall of the heating barrel, the arc surface of the protrusion plate is located on the motion trajectory of the end of the hollow flexible plate away from the L-shaped frame, the sliding arc plate slides toward the center of the heating barrel and resets, driving the L-shaped frame to move synchronously, and the L-shaped frame drives the hollow flexible plate to move synchronously. During the process, the hollow flexible plate drives the elastic strip to move synchronously. When the hollow flexible plate moves toward the center of the heating barrel, it will contact the arc surface of the protruding plate and generate resistance. The hollow flexible plate will bend and deform under the resistance of the protruding plate. As the hollow flexible plate continues to move, it will be able to overcome the resistance of the protruding plate in a bent posture. At this time, the hollow flexible plate will swing back and forth during the process of resetting through its own toughness, and the hollow flexible plate drives the elastic strip to move synchronously. When the elastic strip swings, the vibration frequency of the hollow flexible plate will be enhanced, thereby amplifying the vibration force generated by the swinging of the hollow flexible plate, and the sliding arc plate will be prompted to vibrate synchronously through the transmission of force.

[0014] According to the above technical scheme, the scale shielding device also includes a telescopic baffle, an elastic arc sheet, an L-shaped push plate and a curved scraper. The top of the telescopic baffle is fixedly installed on the bottom of the L-shaped frame, the elastic arc sheet is fixedly installed on the outer wall of the fixed end of the telescopic baffle away from the spiral hose, the bottom of the L-shaped push plate is fixedly installed on the outer wall of the telescopic end of the telescopic baffle close to one end of the spiral hose, and the outer wall of the curved scraper is slidably installed on the outer wall of the fixed end of the telescopic baffle away from the spiral hose.

[0015] According to the above technical scheme, the bottom of the telescopic end of the telescopic baffle is located on the movement trajectory of the top of the cross plate, the telescopic baffle is built with a spring, and the bottom of the arc scraper is fixedly installed on the top of the L-shaped push plate. The L-shaped frame drives the telescopic baffle to move synchronously, and when the telescopic baffle moves toward the center of the heating barrel, it drives the elastic arc plate to move synchronously. The elastic arc plate is limited by two adjacent telescopic baffles to generate a folding force, that is, the outer concave surface of the elastic arc plate gradually turns into a convex surface. At the same time, the cross plate resists the telescopic end of the telescopic baffle during the upward movement. When the telescopic end of the telescopic baffle contracts upward, it drives the L-shaped push plate to move synchronously, and the L-shaped push plate pushes the arc scraper to slide upward along the outer wall of the fixed end of the telescopic baffle.

[0016] The present invention provides a low-temperature vacuum evaporator that can be quickly preheated. It has the following beneficial effects:

[0017] (1) The present invention effectively expands the range of movement of the heating component by setting up a heat mixing device, and by cooperating with an electric rotating rod, a stirring plate, a sleeve, a cross plate, a heating component, a water pumping gun, a spiral hose, an I-beam and an arc panel. At the same time, the stirring plate is relied on to prevent the heating component from always being in a static state when heating the water source inside the heating barrel, thereby affecting the heat exchange efficiency, reducing the temperature fluctuation when the water source is heated, and ensuring that the water source is heated uniformly as a whole. At the same time, the water pumping gun moves synchronously with the heating component, so that even if the water source as a whole is heated unevenly, the temperature of the water source pumped by the water pumping gun is still relatively balanced, thereby preventing the preheating temperature of the liquid in different parts of the device body from being different due to uneven water temperature, thereby affecting the overall preheating effect; and during the revolution and rotation of the arc panel, the scale or other sediments deposited on the bottom of the inner wall of the heating barrel are continuously stirred, and the sediments that are stirred and float upward are concentrated and evenly collected through the U-shaped mesh plate, thereby ensuring the cleanliness of the water source and preventing the scale from continuously eroding the circulation pipe and increasing its rupture risk.

[0018] (2) The present invention sets a convergence device, and cooperates with a transverse plate, a round rod, a spoiler frame, a transverse rod, a flip plate, a guide arc block, a cam, a sliding arc plate and a circular plate. The spoiler frame and the flip plate continuously disturb the water source at the inner edge of the heating barrel to gather it toward the center, and the flip plate continuously flips and swings to accelerate the surge frequency of the water source under the same disturbance frequency of the spoiler frame, that is, to promote the overall heat exchange speed of the water source inside the heating barrel, shorten the waiting time when the device body is used, and further ensure the balance of the water temperature of the transported water source; at the same time, the sliding arc plate continuously resists the spiral hose, causing the spiral hose to generate a shaking force during the water delivery process. The spiral hose relies on continuous shaking to accelerate the smoothness of its internal water delivery, avoiding insufficient water supply in the spiral hose, resulting in bubbles and cavities in the circulation pipe, thereby reducing the vacuum preheating cycle effect of the evaporator.

[0019] (3) The scale shielding device is provided in the present invention. The sliding arc plate, L-shaped frame, hollow flexible plate, elastic strip, convex plate, telescopic baffle, elastic arc sheet, L-shaped push plate and arc scraper are coordinated to make the sliding arc plate carry vibration contact and resist the spiral hose, so that the spiral hose carries slight vibration during the shaking process, that is, the bubbles in the spiral hose are quickly exploded and eliminated, which is convenient for the water source in the remaining part to quickly fill and fill, and ensure that the water source entering the circulation pipe will not cause the formation of cavities inside it, prevent the vacuum degree from being reduced and avoid affecting the rapid preheating efficiency; and rely on the telescopic baffle and the elastic arc sheet to block the water flow disturbed by the spoiler frame to a certain extent, prevent the water source from carrying tiny sediments or scale to directly flush the outer wall of the spiral hose, causing excessive dirt to adhere to the outer wall of the spiral hose and thus accelerate its own oxidation rate, and avoid the spiral hose from being damaged on the surface and thus increasing the bubbles generated during water delivery. At the same time, the dirt on the outer wall of the fixed end of the telescopic baffle is removed by the arc scraper. When it is stationary inside the heating barrel, the dirt settles to the bottom of the inner wall of the heating barrel and is collected by the U-shaped mesh plate at the next start.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] A heat mixing device 4 is arranged inside the heating barrel 3, a converging device 5 is arranged above the heat mixing device 4, and a scale shielding device 6 is arranged outside the converging device 5;

[0033] The heat mixing device 4 includes an electric rotating rod 41, the bottom of which is rotatably installed at the center of the bottom of the inner wall of the heating barrel 3, a plurality of stirring plates 42 are equidistantly and fixedly installed on the outer wall of the bottom end of the electric rotating rod 41, a collar 43 is penetrated through the outer wall of the reciprocating spiral groove of the electric rotating rod 41 and movably installed, a plurality of cross plates 44 are equidistantly and fixedly installed on the outer wall of the collar 43, a heating component 45 is fixedly installed on the end of the cross plate 44 away from the collar 43, a water pumping gun 46 is penetrated through and fixedly installed on the end of the cross plate 44 close to the collar 43, a spiral hose 47 is fixedly installed between the top of the water pump 46 and the bottom of the water pump 31, an I-beam 48 is rotatably installed inside the U-shaped groove of the stirring plate 42, a plurality of arc panels 49 are equidistantly and fixedly installed on the outer wall of the I-beam 48 close to the center end of the stirring plate 42, and a U-shaped mesh plate 410 is slidably installed on the outer wall of the stirring plate 42 through a spring.

[0034] A reciprocating spiral groove is provided on the outer wall of the top of the electric rotating rod 41, and a U-shaped groove is provided on the bottom of the stirring plates 42. The outer wall of the heating component 45 is slidably connected with the inner wall of the heating barrel 3, and the outer walls of the two ends of the I-shaped column 48 are in contact with the bottom of the inner wall of the heating barrel 3. The arc surface of the bottom of the U-shaped mesh plate 410 is located on the movement trajectory of the arc plate 49. Through the above cooperation, the activity range of the heating component 45 is effectively expanded. At the same time, the stirring plate 42 is relied on to prevent the heating component 45 from heating the water source inside the heating barrel 3. The water source is always in a static state, thereby affecting the heat exchange efficiency, reducing the temperature fluctuation when the water source is heated, and ensuring that the water source is heated evenly as a whole. At the same time, the pumping gun 4 6 moves synchronously with the heating component 45, so that even if the temperature of the water source as a whole rises unevenly, the temperature of the water source pumped by the water pumping gun 46 is still relatively balanced, thereby preventing the preheating temperature of the liquid in different parts of the device body 2 from being different due to the uneven water temperature, thereby affecting the overall preheating effect; through the above cooperation, during the revolution and rotation of the arc panel 49, the scale or other sediments deposited on the bottom of the inner wall of the heating barrel 3 are continuously stirred, and the sediments floating upward by the stirring are concentrated and evenly collected through the U-shaped mesh plate 410, thereby ensuring the cleanliness of the water source and preventing the scale from continuously corroding the circulation pipe 21, thereby increasing the risk of its rupture.

[0035] When in use, the electric rotating rod 41 is started, and the electric rotating rod 41 drives the stirring plate 42 to revolve when rotating along the bottom of the inner wall of the heating barrel 3, and the stirring plate 42 revolves and stirs the water source inside the heating barrel 3. At the same time, the electric rotating rod 41 limits the built-in block of the ring 43 through the reciprocating spiral groove on its outer wall, so that the ring 43 can slide upward and reset along the outer wall of the electric rotating rod 41 reciprocatingly, and the ring 43 drives the horizontal plate 44 to move synchronously, and the horizontal plate 44 drives the heating component 45 to move synchronously along the inner wall of the heating barrel 3. At the same time, the horizontal plate 44 drives the water pumping gun 46 to move synchronously, and the water pumping gun 46 drives the spiral hose 47 moves synchronously, the spiral hose 47 supplies water to the inside of the water pump 31 through the water pumping gun 46, and the water pump 31 delivers hot water to the inside of the circulation pipe 21 through the water pipe 32. The hot water will emit heat when circulating in the circulation pipe 21, and the hot steam will quickly fill the cavity between the insulation tank 1 and the device body 2, so as to realize the rapid preheating of the liquid inside the device body 2. The above cooperation effectively expands the range of movement of the heating component 45, and at the same time relies on the stirring plate 42 to prevent the heating component 45 from being in a static state when heating the water source inside the heating barrel 3, thereby affecting the heat The exchange efficiency is improved, and the temperature fluctuation when the water source is heated is reduced to ensure that the water source is heated evenly as a whole. At the same time, the pumping gun 46 moves synchronously with the heating component 45, so that even if the water source as a whole is heated unevenly, the temperature of the water source pumped by the pumping gun 46 is still relatively balanced, thereby preventing the preheating temperature of the liquid in different parts of the device body 2 from being different due to uneven water temperature, thereby affecting the overall preheating effect. When the stirring plate 42 revolves, it drives the I-beam column 48 to move synchronously along the bottom of the inner wall of the heating barrel 3 to generate friction. The I-beam column 48 starts to rotate inside the stirring plate 42 through the friction, and the I-beam column 48 drives The arc panel 49 revolves, and when the arc panel 49 revolves, it disengages from the resistance to the arc surface at the bottom of the U-shaped mesh plate 410. At this time, the U-shaped mesh plate 410 moves downward due to the elastic force of the spring, and when the arc panel 49 resists again, it prompts the U-shaped mesh plate 410 to return to its original position, and this process is repeated repeatedly. Through the above coordination, during the revolution and rotation of the arc panel 49, the scale or other sediments deposited on the bottom of the inner wall of the heating barrel 3 are continuously stirred, and at the same time, the sediments floating upward by the stirring are concentrated and evenly collected through the U-shaped mesh plate 410, thereby ensuring the cleanliness of the water source and preventing the scale from continuously corroding the circulation pipe 21, thereby increasing its risk of rupture.

[0036] See also Figure 1-Figure 9 , based on the above embodiment, another embodiment of the present invention further includes a convergence device 5;

[0037] The converging device 5 includes a round rod 51, a spoiler frame 52, a cross bar 53, a flip plate 54 and a guide arc block 55. The top of the round rod 51 is rotatably installed at the top edge of the inner wall of the heating barrel 3, the spoiler frames 52 are fixedly installed on the outer wall of the top end of the round rod 51, both ends of the cross bar 53 are fixedly installed inside the spoiler frame 52, the flip plate 54 passes through the inside and is hinged on the outer wall of the cross bar 53, the guide arc block 55 is fixedly installed on the outer wall of the flip plate 54 close to the spoiler frame 52, and the surface of the round rod 51 is a non-self-locking spiral groove.

[0038] The bottom of the round rod 51 passes through and is threadedly connected to the inside of the end of the cross plate 44 away from the ring 43. If the interference flow frame 52 is equidistantly distributed on the outer wall of the round rod 51, a torsion spring is arranged between the inside of the flip plate 54 and the cross rod 53. Through the above cooperation, the spoiler frame 52 and the flip plate 54 are used to continuously disturb the water source at the inner edge of the heating barrel 3 to gather toward its center, and the flip plate 54 is continuously flipped and swung to accelerate the surging frequency of the water source at the same disturbance frequency of the spoiler frame 52, that is, to promote the overall heat exchange speed of the water source inside the heating barrel 3, shorten the waiting time when the device body 2 is used, and further ensure the balance of the water temperature of the transported water source.

[0039] The converging device 5 also includes a cam 56, a sliding arc plate 57 and a circular plate 58. The cam 56 passes through and is fixedly installed on the outer wall of the top end of the round rod 51. The top of the sliding arc plate 57 is slidably installed on the top of the inner wall of the heating barrel 3 by a spring. The spiral hose 47 is located on the arc motion trajectory of the sliding arc plate 57. The outer wall of the circular plate 58 is fixedly installed on the end of the sliding arc plate 57 close to the cam 56, and the outer wall of the circular plate 58 is in contact with the cam 56. Through the above cooperation, the sliding arc plate 57 continuously resists the spiral hose 47, causing the spiral hose 47 to generate a shaking force during the water delivery process. The spiral hose 47 relies on continuous shaking to accelerate the smoothness of its internal water source delivery, thereby avoiding insufficient water supply from the spiral hose 47, resulting in bubbles and cavities inside the circulation pipe 21, thereby reducing the vacuum preheating cycle effect on the evaporator.

[0040] When in use, the upward movement of the cross plate 44 will drive the threaded round rod 51 to generate a rotational force. When the round rod 51 rotates along the top of the inner wall of the heating barrel 3, it drives the spoiler frame 52 to revolve. When the spoiler frame 52 revolves, it drives the cross bar 53 to move synchronously. When the cross bar 53 drives the flip plate 54 to revolve, the flip plate 54 will drive the guide arc block 55 to move synchronously. When the guide arc block 55 revolves, it unilaterally guides the water source contacted by its own arc surface. At this time, the flip plate 54 generates a rotational force through the resistance between its own revolution and the water source, as well as the water source guided by the guide arc block 55. The flip plate 54 will start to rotate along the outer wall of the cross bar 53, and then the flip plate 54 will reset through the torsion spring. Through the above cooperation, the spoiler frame 52 and the flip plate 54 continuously disturb the water source at the inner edge of the heating barrel 3 to gather toward its center, and the flip plate 54 continuously flips and swings to accelerate the surge of the water source at the same disturbance frequency of the spoiler frame 52. Frequency, that is, to promote the overall heat exchange speed of the water source inside the heating barrel 3, shorten the waiting time when the device body 2 is used, and further ensure the balance of the water temperature of the transported water source; when the round rod 51 rotates, it drives the cam 56 to rotate. When the cam 56 rotates, it will resist the outer wall of the circular plate 58. The circular plate 58 generates a force to move toward the center of the heating barrel 3 through the resistance of the cam 56. At this time, the circular plate 58 pushes the sliding arc plate 57 to slide synchronously along the inner wall of the heating barrel 3. When the cam 56 is reset, the sliding arc plate 57 will drive the circular plate 58 to reset when it is reset by the spring, and so on. Through the above cooperation, the sliding arc plate 57 continuously resists the spiral hose 47, causing the spiral hose 47 to generate a shaking force during the water delivery process. The spiral hose 47 relies on continuous shaking to accelerate the smoothness of its own internal water source delivery, avoiding insufficient water supply of the spiral hose 47, resulting in bubbles and cavities in the circulation pipe 21, thereby reducing the vacuum preheating cycle effect of the evaporator.

[0041] See also Figure 1-Figure 9 , based on the above embodiment, another embodiment of the present invention further includes a scale shielding device 6;

[0042] The scale shielding device 6 includes an L-shaped frame 61, a hollow flexible plate 62, an elastic strip 63 and a protrusion plate 64. The L-shaped frame 61 is fixedly installed on the outer wall of the sliding arc plate 57 near the cam 56, the hollow flexible plate 62 is fixedly installed on the outer wall of the L-shaped frame 61 near the cam 56, the elastic strip 63 is fixedly installed on the outer wall of the L-shaped frame 61 near the circular plate 58, and the top of the protrusion plate 64 is fixedly installed on the top of the inner wall of the heating barrel 3. The arc surface of the protrusion plate 64 is located on the movement trajectory of the end of the hollow flexible plate 62 away from the L-shaped frame 61. Through the above cooperation, the sliding arc plate 57 is caused to carry out vibration contact and resist the spiral hose 47, so that the spiral hose 47 carries a slight vibration during the shaking process, that is, the bubbles in the spiral hose 47 are quickly exploded and eliminated, so that the remaining water source can be quickly supplemented and filled, ensuring that the water source entering the circulation pipe 21 will not cause a cavity to be formed inside it, preventing the vacuum degree from being reduced and avoiding affecting the rapid preheating efficiency.

[0043] The scale shielding device 6 also includes a telescopic baffle 65, an elastic arc sheet 66, an L-shaped push plate 67 and a curved scraper 68. The top of the telescopic baffle 65 is fixedly installed on the bottom of the L-shaped frame 61, the elastic arc sheet 66 is fixedly installed on the outer wall of the fixed end of the telescopic baffle 65 away from the spiral hose 47, the bottom of the L-shaped push plate 67 is fixedly installed on the outer wall of the telescopic end of the telescopic baffle 65 close to one end of the spiral hose 47, and the outer wall of the curved scraper 68 is slidably installed on the outer wall of the fixed end of the telescopic baffle 65 away from the spiral hose 47.

[0044] The bottom of the telescopic end of the telescopic baffle 65 is located on the movement trajectory of the top of the horizontal plate 44. The telescopic baffle 65 has a built-in spring, and the bottom of the arc scraper 68 is fixedly installed on the top of the L-shaped push plate 67. Through the above cooperation, the telescopic baffle 65 and the elastic arc sheet 66 are used to block the water flow disturbed by the spoiler frame 52 to a certain extent, thereby preventing the water source from carrying tiny sediments or scale to directly flush the outer wall of the spiral hose 47, causing excessive dirt to adhere to the outer wall of the spiral hose 47, thereby accelerating its own oxidation rate, and avoiding the spiral hose 47 from being damaged on the surface and increasing the bubbles generated during water delivery. At the same time, the dirt on the outer wall of the fixed end of the telescopic baffle 65 is removed by the arc scraper 68. When it is stationary inside the heating barrel 3, the dirt settles to the bottom of the inner wall of the heating barrel 3, and is collected by the U-shaped mesh plate 410 when it is started next time.

[0045] When in use, the sliding arc plate 57 slides toward the center direction of the heating barrel 3 and drives the L-shaped frame 61 to move synchronously when it is reset. During the process of the L-shaped frame 61 driving the hollow flexible plate 62 to move synchronously, the hollow flexible plate 62 drives the elastic strip 63 to move synchronously. During the process of the hollow flexible plate 62 moving toward the center direction of the heating barrel 3, it will contact with the arc surface of the protruding plate 64 and generate a resistance force. The hollow flexible plate 62 will bend and deform under the resistance of the protruding plate 64. As the hollow flexible plate 62 continues to move, it can pass through the resistance of the protruding plate 64 in a bent posture. At this time, the hollow flexible plate 62 will be reset through its own toughness. The hollow flexible plate 62 swings back and forth, and the elastic strip 63 drives the synchronous movement. When the elastic strip 63 swings, the vibration frequency of the hollow flexible plate 62 is enhanced, thereby amplifying the vibration force generated by the swing of the hollow flexible plate 62, and the sliding arc plate 57 is caused to vibrate synchronously through the transmission of force. Through the above cooperation, the sliding arc plate 57 is caused to carry vibration contact and resist the spiral hose 47, so that the spiral hose 47 carries a slight vibration during the shaking process, that is, the bubbles in the spiral hose 47 are quickly exploded and eliminated, so that the remaining water source is quickly filled, and it is ensured that the water source entering the circulation pipe 21 will not cause the inside thereof. The L-shaped frame 61 drives the telescopic baffle 65 to move synchronously, and the telescopic baffle 65 drives the elastic arc piece 66 to move synchronously when it moves toward the center of the heating barrel 3. The elastic arc piece 66 is limited by two adjacent telescopic baffles 65 to generate a folding force, that is, the outer concave surface of the elastic arc piece 66 gradually changes to a convex surface. At the same time, the horizontal plate 44 contacts the telescopic end of the telescopic baffle 65 during the upward movement. When the telescopic end of the telescopic baffle 65 shrinks upward, it drives the L-shaped push plate 67 to move synchronously, and the L-shaped push plate 67 pushes the arc scraper 68 along the telescopic baffle 65. The outer wall of the fixed end slides upward, and through the above cooperation, the telescopic baffle 65 and the elastic arc sheet 66 are used to block the water flow disturbed by the spoiler frame 52 to a certain extent, preventing the water source from carrying tiny sediments or scale directly scouring the outer wall of the spiral hose 47, causing excessive dirt to adhere to the outer wall of the spiral hose 47, thereby accelerating its own oxidation rate, and avoiding the spiral hose 47 from being damaged on the surface and increasing the bubbles generated during water delivery. At the same time, the dirt on the outer wall of the fixed end of the telescopic baffle 65 is removed by the arc scraper 68. When it is stationary inside the heating barrel 3, the dirt settles to the bottom of the inner wall of the heating barrel 3, and is collected by the U-shaped mesh plate 410 when it is started next time.
