Description

Technical Field

[0001] This invention relates to the field of energy-saving humidifier technology, and in particular to an energy-saving humidifier. Background Technology

[0002] Traditional energy-saving humidifiers use a water pump to deliver water from a tank to the top of the wet curtain. Under gravity, the water forms a film on the surface of the wet curtain, and water molecules evaporate when dry air passes through the wet curtain, thus achieving humidification. However, after long-term use, calcium and magnesium ions in tap water will form scale on the surface of the wet curtain, clogging the water absorption micropores and causing a significant decrease in humidification efficiency.

[0003] Patent CN210485950U, entitled "A Variable Frequency Controlled Evaporative Cooling Fan," discloses a technical solution with a detachable evaporative cooling pad. By removing the evaporative cooling pad from the casing, it is easy to thoroughly clean dust and other impurities from all surfaces of the pad and to facilitate pad replacement. However, this solution places the evaporative cooling pad above the water tank, resulting in a larger overall structural footprint. Summary of the Invention

[0004] Therefore, there is a need to provide an energy-saving humidifier to solve the technical problem of placing the wet curtain above the water tank, which results in a large overall structural space occupation.

[0005] To achieve the above objectives, the present invention provides an energy-saving humidifier, comprising:

[0006] The housing includes a housing body, an air inlet door, and an air outlet door. The air inlet door is detachably installed on the back of the housing body and has a main air inlet. The air outlet door is detachably installed on the front of the housing body and has a main air outlet door.

[0007] The humidifier is housed within a casing and includes a water tank, a water supply assembly, a humidification assembly, and a fan assembly. The main body of the casing covers the water tank. The water outlet of the water supply assembly is detachably connected to the water inlet of the humidifier assembly. The humidifier assembly includes a frame and a humidifying membrane installed within the frame. The air outlet of the fan assembly is aligned with the air inlet of the humidifying membrane, and the fan assembly blows air onto the humidifying membrane. The humidifying membrane includes a wet curtain, which allows water to evaporate into the outside air.

[0008] The lifting device includes a lifting component and a lifting base. The lifting component is installed in the water tank. The output end of the lifting component is connected to the lifting base. A humidifying component is installed on the lifting base. The lifting component raises the humidifying component so that the height of the humidifying component along the height direction of the shell is higher than the height of the water tank along the height direction of the shell.

[0009] The cleaning device is installed in the water tank and aligned with the wet curtain. The cleaning device cleans the wet curtain.

[0010] Unlike existing technologies, the above-mentioned solution places the evaporative cooling pad inside the water tank during normal use, resulting in a compact overall structure and reduced space occupation for the energy-saving humidifier. When cleaning the cooling pad is required, the detachable connection between the water outlet of the water supply component and the water inlet of the humidification component allows the humidification component to be lifted using a lifting device and removed from the water tank. This enables thorough cleaning of the humidification membrane or direct replacement, effectively removing deep-seated scale and ensuring long-term stable operation of the equipment. Furthermore, a cleaning device installed within the water tank can be used to periodically clean the cooling pad, further reducing scale buildup.

[0011] As one embodiment of the present invention, the humidification assembly also includes four lockable casters, which are installed at the four corners of the bottom of the frame.

[0012] Thus, by installing locking casters at the four corners of the bottom of the frame, it is easy to remove the frame from the water tank for deep cleaning or direct replacement. In addition, after the humidifying membrane has been deeply cleaned, it is also easy to put the frame back into the water tank and lock the casters to fix the position of the frame and prevent it from shifting during use.

[0013] In one embodiment of the present invention, a slot is provided on the upper half of one side of the water tank, and the humidification device also includes a mounting plate. The mounting plate is inserted into the slot, and the lifting component raises the humidification component so that the height of the humidification component along the height direction of the shell is higher than the height of the bottom of the slot along the height direction of the shell.

[0014] In this way, by using the mounting plate and the slot together, the height of the lifting component when raising the humidification component can be reduced without affecting the normal use of the water tank.

[0015] In one embodiment of the present invention, the lifting assembly includes two first hydraulic rods spaced apart along the width direction of the housing;

[0016] When the humidification component needs deep cleaning, the two first hydraulic rods control the lifting base to tilt towards the slot. The height of one of the first hydraulic rods closer to the slot along the height direction of the housing is lower than the height of the other first hydraulic rod farther away from the slot along the height direction of the housing.

[0017] After the humidification component has been thoroughly cleaned, the two first hydraulic rods control the lifting base to tilt away from the slot. The height of the first hydraulic rod closer to the slot along the height direction of the housing is higher than the height of the other first hydraulic rod farther from the slot along the height direction of the housing.

[0018] Thus, depending on the different states of the humidification component, the two first hydraulic rods are positioned at different heights to create a height difference, making it easier to remove or place the humidification component into the water tank.

[0019] As one embodiment of the present invention, the humidification device further includes two limiting blocks, which are installed opposite to each other on both sides of the water tank. The frame is located between the two limiting blocks, and the two limiting blocks restrict the frame from moving along the width direction of the shell.

[0020] Thus, when the frame is installed in the water tank, the two limiting blocks cooperate to restrict the frame from moving along the width direction of the shell.

[0021] As one embodiment of the present invention, the humidification device further includes two limiting baffles. The two limiting baffles extend along the width direction of the shell and are installed in the water tank. The two limiting baffles are located at the air inlet and air outlet of the humidification membrane, respectively, and the two limiting baffles restrict the frame from moving along the length direction of the shell.

[0022] Similarly, when the frame is installed in the water tank, two limiting baffles can be used to further restrict the movement of the frame along the length of the shell, so as to achieve precise positioning and ensure that the air outlet of the wet curtain and the fan assembly are precisely aligned.

[0023] In one embodiment of the present invention, the cleaning device includes a cleaning assembly, which includes a mounting frame, a movable lead screw, a moving drive unit, a spray pipe, a cleaning pipe, and two or more nozzles. The mounting frame is installed in a water tank and located at the air outlet of the humidifying membrane. The movable lead screw extends along the height direction of the housing and is installed on the mounting frame. The moving drive unit is installed on the top of the mounting frame and its output end is connected to the movable lead screw. The spray pipe is sleeved outside the movable lead screw and is threadedly connected to the movable lead screw. The water inlet of the spray pipe is connected to the water outlet of the cleaning pipe. Two or more nozzles are installed on the side of the spray pipe facing the wet curtain. The moving drive unit drives the movable lead screw to rotate, and the spray pipe reciprocates along the height direction of the housing.

[0024] In this way, the spray pipe can move back and forth along the height of the housing under the action of the mobile drive unit, thereby cleaning the wet curtain and reducing the scale on the wet curtain.

[0025] In one embodiment of the present invention, the cleaning device further includes a guide assembly, which includes a guide rod and a guide block. The guide rod extends along the height direction of the housing and is mounted on the mounting bracket. The guide block is sleeved on the guide rod and slides outside the guide rod. The guide block is connected to the spray pipe.

[0026] In this way, by setting up a guide component to improve the stability of the spray pipe movement, the distance between the nozzle and the wet curtain is kept constant, thereby improving the water flow impact effect.

[0027] As one embodiment of the present invention, the cleaning device further includes a reciprocating lateral movement component, which causes the spray pipe to reciprocate along the width direction of the housing.

[0028] In this way, by superimposing the cleaning components with the reciprocating horizontal moving components, the spray pipe can move back and forth along both the height and width of the shell, forming a grid-like cleaning path and improving the descaling efficiency.

[0029] In one embodiment of the present invention, the cleaning assembly further includes a cleaning tank and a control valve. The cleaning tank is filled with cleaning agent, the outlet of the cleaning tank is connected to the inlet of the cleaning pipe, and the control valve is installed on the cleaning pipe.

[0030] In this way, the concentration of the cleaning agent can be intelligently adjusted according to the thickness of the scale by controlling the valve, which improves the efficiency of dissolving calcium and magnesium scale while protecting the fiber structure of the wet curtain.

[0031] The above description of the invention is merely an overview of the technical solution of this application. In order to enable those skilled in the art to better understand the technical solution of this application and to implement it based on the description and drawings, and to make the above-mentioned objectives and other objectives, features and advantages of this application easier to understand, the following description is provided in conjunction with the specific embodiments and drawings of this application.

[0058] While existing technologies disclose detachable evaporative cooling pads, these solutions place the evaporative cooling pads above the water tank, resulting in a large overall structural footprint.

[0059] In view of this, this application provides an energy-saving humidifier 100, including a housing 1, a humidifying device 2, a lifting device 4, and a cleaning device 3. The housing 1 includes a housing body 11, an air inlet 12, and an air outlet 12. The air inlet 12 is detachably installed on the back of the housing body 11 and has a main air inlet. The air outlet 12 is detachably installed on the front of the housing body 11 and has a main air outlet. The humidifying device 2 is disposed inside the housing 1 and includes a water tank 21, a water supply assembly 22, a humidifying assembly 23, and a fan assembly 24. The housing body 11 covers the water tank 21. The water outlet of the water supply assembly 22 is detachably connected to the water inlet of the humidifying assembly 23. The humidifying assembly 23 includes a frame 231 and a fan assembly 24 mounted on the frame 231. The humidifying membrane 232 inside the tank 21 has its air outlet aligned with the air inlet of the fan assembly 24, which blows air onto the humidifying membrane 232. The humidifying membrane 232 includes a wet curtain 2321, which allows water to evaporate into the outside air. The lifting device 4 includes a lifting component 41 and a lifting base 42. The lifting component 41 is installed inside the water tank 21, and its output end is connected to the lifting base 42. A humidifying component 23 is installed on the lifting base 42. The lifting component 41 raises the humidifying component 23 so that the height of the humidifying component 23 along the height Z direction of the housing is higher than the height of the water tank 21 along the height Z direction of the housing. The cleaning device 3 is installed inside the water tank 21 and aligned with the wet curtain 2321. The cleaning device 3 cleans the wet curtain 2321.

[0060] According to some embodiments of this application, please refer to Figures 1 to 12This embodiment relates to an energy-saving humidifier 100, including a housing 1, a humidifying device 2, a lifting device 4, and a cleaning device 3. The housing 1 includes a housing body 11, an air inlet 12, and an air outlet. The air inlet 12 is detachably installed on the back of the housing body 11 and has a main air inlet. The air outlet 12 is detachably installed on the front of the housing body 11 and has a main air outlet. The humidifying device 2 is disposed inside the housing 1 and includes a water tank 21, a water supply assembly 22, a humidifying assembly 23, and a fan assembly 24. The housing body 11 covers the water tank 21. The water outlet of the water supply assembly 22 is detachably connected to the water inlet of the humidifying assembly 23. The humidifying assembly 23 includes a frame 231 and components installed inside the frame 231. The humidifying membrane 232 has its air outlet aligned with the air inlet of the fan assembly 24, which blows air onto it. The humidifying membrane 232 includes a wet curtain 2321, which allows water to evaporate into the outside air. The lifting device 4 includes a lifting component 41 and a lifting base 42. The lifting component 41 is installed inside the water tank 21, and its output end is connected to the lifting base 42. A humidifying component 23 is mounted on the lifting base 42. The lifting component 41 raises the humidifying component 23 so that its height along the height Z direction of the housing is higher than that of the water tank 21 along the height Z direction of the housing. The cleaning device 3 is installed inside the water tank 21 and aligned with the wet curtain 2321. The cleaning device 3 cleans the wet curtain 2321.

[0061] The main body 11 is detachably connected to the water tank 21, covering the water tank 21. When the water tank 21 needs to be opened, the main body 11 can be removed; when the water tank 21 needs to be closed, the main body 11 can be re-covered. The water tank 21 is used for water storage and collection of return water. An air inlet 12 is detachably mounted (using clips or bolts) on the back of the main body 11, and an air outlet 12 is detachably mounted (using clips or bolts) on the front of the main body 11.

[0062] like Figure 2As shown, the water delivery assembly 22 includes a water pump 221 and a water delivery pipe 222. The inlet of the water pump 221 is connected to the water tank 21, and the outlet of the water pump 221 is connected to the inlet of the water delivery pipe 222. The outlet of the water delivery pipe 222 is detachably connected to the inlet of the frame 231 (which can be a threaded connection, a butt joint connection, or a pipe clamp connection). Specifically, the water pump 221 can be directly installed at the bottom of the water tank 21. The water pump 221 draws water from the water tank 21 and delivers it through the water delivery pipe 222 to the water sprinkler (not shown in the figure) at the top of the frame 231, where it evenly wets the wet curtain 2321. The humidifying membrane 232 has the wet curtain 2321 built into it, and it is made of hydrophilic fiber material, forming a uniform water film through capillary action. The fan assembly 24 blows air onto the evaporative cooling pad 2321 to accelerate water molecule evaporation (the fan assembly 24 is an existing structure, generally including a fan motor and fan blades; the fan motor drives the fan blades to rotate, and the fan blades draw air in from the main air inlet and blow it onto the humidifying membrane 232), finally humidifying the outside air through the main air outlet. Preferably, the water supply pipe 222 is a flexible pipe, so that when the frame 231 undergoes a certain displacement, the flexibility of the water supply pipe 222 allows it to be aligned and connected with the water inlet of the frame 231. In some embodiments, such as Figures 3 to 6 As shown, the humidifying assembly 23 also includes a handle 234, which is mounted on the frame 231. The handle 234 can be mounted on the top and / or side of the frame 231, allowing staff to easily access the frame 231 from different angles.

[0063] The evaporative humidifier 2321 has two states. When the energy-saving humidifier 100 is in normal use, the bottom of the evaporative humidifier 2321 is located inside the water tank 21, reducing the space occupied by the evaporative humidifier 2321. When the evaporative humidifier 2321 needs to be replaced after long-term use, the energy-saving humidifier 100 is stopped and the lifting device 4 is used to raise the humidification component 23. The humidification component 23 is then removed from the water tank 21 to thoroughly clean the humidification membrane 232 or replace it directly. This thoroughly removes deep scale and ensures the long-term stable operation of the equipment.

[0064] The cleaning device 3 can be an existing cleaning structure, which can clean the wet curtain 2321 inside the housing 1 at any time or at regular intervals (such as daily or bi-weekly) to reduce scale buildup in the wet curtain 2321. Based on this, the need for deep cleaning or replacement of the wet curtain 2321 can be reduced (it can be set to be done once every six months or a year).

[0065] Optionally, the dimensions of the lifting base along the length direction X and the width direction Y of the housing are equal to the dimensions of the frame 231 along the length direction X and the width direction Y of the housing.

[0066] In some embodiments, such as Figure 2As shown, the energy-saving humidifier 100 also includes an inlet pipe 5, a drain pipe 6, and a drain valve 61. The inlet pipe 5 and the drain pipe 6 are installed on one side outside the water tank 21. The inlet of the inlet pipe 5 and the inlet of the drain pipe 6 are both connected to the main inlet pipe 5, and a drain valve 61 is provided on the drain pipe 6. The drain valve 61 can be an electronic valve or a manual valve.

[0067] Unlike existing technologies, the above-mentioned technical solution places the evaporative cooling pad 2321 within the water tank 21 during normal use, resulting in a compact overall structure for the energy-saving humidifier 100 and reduced space occupation. When cleaning the evaporative cooling pad 2321 is required, based on the detachable connection between the outlet of the water supply component 22 and the inlet of the humidification component 23, the humidification component 23 can be lifted using the lifting device 4 and removed from the water tank 21. This allows for thorough cleaning of the humidification membrane 232 or direct replacement, effectively removing deep-seated scale and ensuring long-term stable operation of the equipment. Furthermore, the cleaning device 3 installed within the water tank 21 can be used to periodically clean the evaporative cooling pad 2321, reducing scale buildup.

[0068] like Figure 4 As shown, the humidifying device 2 includes four lockable casters 233, which are installed at the four corners of the bottom of the frame 231.

[0069] Lockable caster 233 is existing technology and will not be described further. Lockable caster 233 can be locked or unlocked.

[0070] Thus, by providing locking casters 233 at the four corners of the bottom of the frame 231, it is easy to remove the frame 231 from the water tank 21 for deep cleaning or direct replacement. In addition, after the humidifying membrane 232 has been deeply cleaned, it is also easy to put the frame 231 back into the water tank 21 and lock the casters to fix the position of the frame 231 and prevent the frame 231 from shifting during use.

[0071] like Figure 2 As shown, a slot 211 is provided on the upper half of one side of the water tank 21. The humidifying device 2 also includes a mounting plate 25. The mounting plate 25 is inserted into the slot 211. The lifting component 41 raises the humidifying component 23 so that the height of the humidifying component 23 along the height direction Z of the shell is higher than the bottom of the slot 211 along the height direction Z of the shell.

[0072] A slot 211 is provided in the upper half of one side (left or right) of the water tank 21. The position of the slot 211 does not interfere with the water in the water tank 21, meaning the water level in the water tank 21 is lower than the bottom of the slot 211. Therefore, the mounting plate 25 does not need to be sealed to the slot 211. Optionally, the mounting plate 25 can be made of transparent material to facilitate observation of the water level in the water tank 21. When deep cleaning of the humidifying component 23 is required, the mounting plate 25 is removed from the slot 211, and the humidifying component 23 is raised by the lifting component 41 and removed from the lifting base 42 for cleaning. After the humidifying component 23 is cleaned, it is placed back on the lifting base 42, and the position of the humidifying component 23 is lowered by the lifting component 41 until the humidifying component 23 returns to its original position. Finally, the mounting plate 25 is inserted into the slot 211.

[0073] In this way, by cooperating with the mounting plate 25 and the slot 211, the height of the lifting component 41 when raising the humidifying component 23 can be reduced without affecting the normal use of the water tank 21.

[0074] like Figure 5 and Figure 6 As shown, the lifting assembly 41 includes two first hydraulic rods 411 spaced apart along the width direction Y of the housing. When the humidifying assembly 23 requires deep cleaning, the two first hydraulic rods 411 control the lifting base 42 to tilt towards the slot 211. The height of one of the first hydraulic rods 411 near the slot 211 along the height direction Z of the housing is lower than the height of the other first hydraulic rod 411 away from the slot 211 along the height direction Z of the housing. After the humidifying assembly 23 has been deeply cleaned, the two first hydraulic rods 411 control the lifting base 42 to tilt away from the slot 211. The height of one of the first hydraulic rods 411 near the slot 211 along the height direction Z of the housing is higher than the height of the other first hydraulic rod 411 away from the slot 211 along the height direction Z of the housing.

[0075] The first hydraulic rod 411 raises or lowers the lifting base 42 along the height direction Z of the housing. The lifting assembly 41 can also be a lifting rod or other lifting device to raise or lower the lifting base 42. In some embodiments, the lifting assembly 41 further includes two second hydraulic rods spaced apart along the width direction Y of the housing, each first hydraulic rod 411 corresponding to one second hydraulic rod, and operating synchronously. The first and second hydraulic rods are spaced apart along the length direction X of the housing. The cooperation between the second and first hydraulic rods 411 allows for better support of the humidification assembly 23 and better control of the tilt direction of the lifting base 42.

[0076] In practical use, such as Figure 5As shown, when the humidifying component 23 requires deep cleaning, the two first hydraulic rods 411 control the lifting base 42 to tilt towards the slot 211. The height (H1) of one of the first hydraulic rods 411 near the slot 211 along the height direction Z of the housing is lower than the height (H2) of the other first hydraulic rod 411 away from the slot 211 along the height direction Z of the housing. At the same time, the height of the humidifying component 23 along the height direction Z of the housing is higher than the bottom height of the slot 211 along the height direction Z of the housing, thereby removing the humidifying component 23 from the water tank 21. Figure 6 As shown, after the humidification component 23 has been deeply cleaned, the two first hydraulic rods 411 control the lifting base 42 to tilt away from the slot 211. The height (H1) of one of the first hydraulic rods 411 near the slot 211 along the height direction Z of the housing is higher than the height (H2) of the other first hydraulic rod 411 away from the slot 211 along the height direction Z of the housing, which makes it easier to put the humidification component 23 into the water tank 21.

[0077] Thus, depending on the different states of the humidification component 23, the two first hydraulic rods 411 are positioned at different heights to create a height difference, which facilitates the removal or placement of the humidification component 23 into the water tank 21.

[0078] like Figure 7 As shown, the humidifying device 2 also includes two limiting blocks 26, which are installed opposite each other on both sides of the water tank 21. The frame 231 is located between the two limiting blocks 26, and the two limiting blocks 26 restrict the frame 231 from moving along the width direction Y of the shell.

[0079] The limiting block 26 can be a protrusion, and the corresponding limiting block 26 can be installed on both sides of the water tank 21 by bolts or direct welding. The length of the limiting block 26 along the length X of the housing is less than or equal to the length of the frame 231 along the length X of the housing. The setting of the limiting block 26 does not affect the raising or lowering of the humidifying component 23 by the lifting component 41, and two limiting blocks 26 can be slidably connected to both sides of the humidifying component 23.

[0080] Thus, when the frame 231 is installed in the water tank 21, the two limiting blocks 26 cooperate to restrict the frame 231 from moving along the width direction Y of the shell.

[0081] like Figure 2 and Figure 7 As shown, the humidifying device 2 also includes two limiting baffles 27. The two limiting baffles 27 extend along the width direction Y of the shell and are installed in the water tank 21. The two limiting baffles 27 are located at the air inlet and air outlet of the humidifying membrane 232, respectively. The two limiting baffles 27 restrict the frame 231 from moving along the length direction X of the shell.

[0082] The limiting baffle 27 is installed inside the water tank 21, which does not affect the main air inlet and the main air outlet, nor does it affect the lifting component 41 from raising or lowering the humidifying component 23. Two limiting baffles 27 can be set to slide and connect with the front and back of the humidifying component 23.

[0083] Similarly, when the frame 231 is installed in the water tank 21, the two limiting baffles 27 can further restrict the movement of the frame 231 along the length direction X of the shell for precise positioning, thereby ensuring that the wet curtain 2321 and the air outlet of the fan assembly 24 are precisely aligned.

[0084] like Figure 2 , Figure 8 and Figure 9 As shown, the cleaning device 3 includes a cleaning assembly 31, which includes a mounting frame 311, a movable screw 312, a moving drive unit 313, a spray pipe 314, a cleaning pipe 316, and two or more nozzles 317. The mounting frame 311 is installed inside the water tank 21 and located at the air outlet of the humidifying membrane 232. The movable screw 312 extends along the height direction Z of the housing and is installed on the mounting frame 311. The moving drive unit 313 is installed on the top of the mounting frame 311, and the output end of the moving drive unit 313 is connected to the movable screw 312. The spray pipe 314 is sleeved on the movable screw 312 and threadedly connected to the movable screw 312. The water inlet of the spray pipe 314 is connected to the water outlet of the cleaning pipe 316. Two or more nozzles 317 are installed on the side of the spray pipe 314 facing the wet curtain 2321. The moving drive unit 313 drives the movable screw 312 to rotate, and the spray pipe 314 reciprocates along the height direction Z of the housing.

[0085] The mounting bracket 311 includes a mounting base 3111, on which a movable drive unit 313 is fixedly mounted. The spray pipe 314 is linked to the movable drive unit 313 (which may be a motor, capable of forward or reverse rotation) via a movable lead screw 312, and moves up and down reciprocally along the height direction Z of the housing. Optionally, the cleaning assembly 31 also includes a threaded sleeve 315, through which the spray pipe 314 is threadedly connected to the movable lead screw 312.

[0086] The inlet of the cleaning pipe 316 can be directly connected to the water tank 21 via the first cleaning pump, allowing direct use of the water in the water tank 21 for cleaning and avoiding water waste. The inlet of the cleaning pipe 316 can also be connected to an external water tank or cleaning tank 3191 via the second cleaning pump.

[0087] Thus, the spray pipe 314 can reciprocate along the height direction Z of the housing under the action of the moving drive unit 313, thereby cleaning the wet curtain 2321 and reducing the scale on the wet curtain 2321.

[0088] In some embodiments, the cleaning device 3 includes a cleaning assembly, which includes a cleaning motor, a cleaning screw, and a cleaning brush. The cleaning motor is mounted on the frame 231, and the output end of the cleaning motor is connected to the cleaning screw. The cleaning screw extends along the height direction Z of the housing and is disposed on the frame 231. The cleaning brush extends along the width direction Y of the housing and is sleeved on the cleaning screw. The cleaning brush is threadedly connected to the cleaning screw, and the two sides of the cleaning brush slide against the two sides of the frame 231. The brush surface of the cleaning brush is in contact with the wet curtain 2321.

[0089] Thus, the sweeping brush moves up and down along the height Z direction of the housing to clean the wet curtain 2321 under the linkage of the sweeping screw and the sweeping motor.

[0090] like Figure 8 and Figure 9 As shown, the cleaning device 3 also includes a guide assembly 32, which includes a guide rod 321 and a guide block 322. The guide rod 321 extends along the height direction Z of the housing and is mounted on the mounting bracket 311. The guide block 322 is sleeved on the guide rod 321 and slides outside the guide rod 321. The guide block 322 is connected to the spray pipe 314.

[0091] When the cleaning assembly 31 also includes a threaded sleeve 315, the guide block 322 is connected to the spray pipe 314 through the threaded sleeve 315. The guide block 322 slides up and down along the guide rod 321 in the height direction Z of the housing. The working principle of the cleaning assembly 31 is as follows: When the humidifying membrane 232 needs to be cleaned, the moving drive unit 313 is activated. The moving drive unit 313 drives the moving screw 312 to rotate, causing the threaded sleeve 315 to drive the guide block 322 to slide down along the guide rod 321. The spray pipe 314 slides down with the threaded sleeve 315, and the nozzles 317 on the spray pipe 314 begin to rinse the scale on the wet curtain 2321. When the threaded sleeve 315 slides to the bottom of the moving screw 312, the moving drive unit 313 drives the moving screw 312 to reverse, causing the spray pipe 314 to rise accordingly. This process is repeated to achieve reciprocating rinsing of the wet curtain 2321 by the nozzles 317.

[0092] Thus, by setting the guide component 32, the stability of the spray pipe 314 is improved, thereby ensuring that the distance between the nozzle 317 and the wet curtain 2321 is constant and improving the water flow impact effect.

[0093] like Figures 8 to 11 As shown, the cleaning device 3 also includes a reciprocating transverse component 33, which causes the spray pipe 314 to reciprocate along the width direction Y of the housing.

[0094] The reciprocating lateral movement component 33 can be selected from a gear 335 rack and pinion or a synchronous belt mechanism to drive the spray pipe 314 to reciprocate along the width direction of the housing 1, thereby achieving lateral scanning cleaning. In this embodiment, as... Figures 8 to 11As shown, the reciprocating lateral movement assembly 33 also includes a base plate 332, a first connecting plate 333, a rotating shaft 334, a gear 335, a cam 336, a toothed plate 337, a second connecting plate 338, a limiting rod 3391, and an elastic element 3392. The base plate 332 is installed below the spray pipe 314, and the bottom of the spray pipe 314 slides on the base plate 332 along the width direction Y of the housing. The first connecting plate 333 is installed on one side of the base plate 332, and the rotating shaft 334 is rotatably connected inside the first connecting plate 333. The two ends of the rotating shaft 334 are respectively connected to the gear 335 and the cam 336. 335 engages with toothed plate 337, which is mounted on one side of mounting bracket 311 along the height direction Z of the housing. A second connecting plate 338 is mounted on the other side of base plate 332. A limiting rod 3391 is mounted on the corresponding side of the second connecting plate 338 of spray pipe 314. The limiting rod 3391 is parallel to the width direction Y of the housing. The second connecting plate 338 is sleeved outside the limiting rod 3391 and slides outside it. An elastic element 3392 is sleeved outside the limiting rod 3391, with its two sides connected to spray pipe 314 and the second connecting plate 338, respectively. The elastic element 3392 is elastic, capable of elastically contracting under pressure and returning to its initial shape when the pressure is removed. The elastic element 3392 can be made of metallic elastic materials such as metal springs, or non-metallic elastic materials such as rubber or silicone. Optionally, when the cleaning assembly 31 further includes a threaded sleeve 315, the reciprocating transverse assembly 33 further includes a connecting bracket 331, which is connected to the threaded sleeve 315, and a base plate 332 is fixedly installed on the connecting bracket 331.

[0095] The working principle of the reciprocating lateral movement assembly 33 is as follows: During the reciprocating movement of the spray pipe 314 along the height direction Z of the housing, the gear 335 continuously meshes with the toothed plate 337, causing the rotating shaft 334 to drive the cam 336 to rotate. This causes the cam 336 to continuously contact the side wall of the spray pipe 314, and drives the spray pipe 314 to slide along the width direction Y of the housing on the bottom plate 332. The spray pipe 314 then drives the limiting rod 3391 to slide relative to the second connecting plate 338 and compress the elastic element 3392. When the cam 336 is not in contact with the spray pipe 314, the spray pipe 314 quickly returns to its original position under the elastic force of the elastic element 3392 until the cam 336 contacts the spray pipe 314 again. This reciprocating motion causes the spray pipe 314 to drive the nozzle 317 to move back and forth along the width direction Y of the housing.

[0096] In some embodiments, gear 335 and toothed plate 337 can be omitted, and cam 336 can be rotated directly by transverse motor, which is simpler.

[0097] Thus, by superimposing the cleaning component 31 on the reciprocating horizontal moving component 33, the spray pipe 314 can reciprocate both along the height direction Z of the shell and along the width direction Y of the shell, forming a gridded cleaning path and improving the descaling efficiency.

[0098] like Figure 8 As shown, the cleaning assembly 31 also includes a flow guide 318, which is installed at the outlet of the nozzle 317 and is flat.

[0099] In this way, the flow guide 318 can transform the water flow into a fan-shaped mist, expand the rinsing range of the nozzle 317, and make up for the rinsing gap between adjacent nozzles 317.

[0100] like Figure 12 As shown, the cleaning assembly 31 also includes a cleaning tank 3191 and a control valve 3192. The cleaning tank 3191 is filled with cleaning agent. The outlet of the cleaning tank 3191 is connected to the inlet of the cleaning pipe 316. The control valve 3192 is installed on the cleaning pipe 316.

[0101] The cleaning assembly 31 also includes a second cleaning pump, which is installed on the cleaning pipe 316 or at the bottom of the cleaning tank 3191.

[0102] The cleaning agent can be acidic or chelated, and is delivered to the spray pipe 314 through the cleaning pipe 316, and finally sprayed through the nozzle 317. The control valve 3192 can adjust the flow rate of the cleaning agent to achieve metered spraying.

[0103] In this way, the concentration of the cleaning agent can be intelligently adjusted according to the thickness of the scale by controlling valve 3192, which improves the efficiency of dissolving calcium and magnesium scale while protecting the fiber structure of the wet curtain 2321.

[0104] In some embodiments, the energy-saving humidifier 100 further includes a control device, which is communicatively connected to the humidifying device 2, the cleaning device 3, and the lifting device 4. The control device enables unified control, making it more convenient and intelligent. In other embodiments, the energy-saving humidifier 100 also includes a wind sensor and an alarm. The wind sensor is installed at the air outlet of the humidifying membrane 232 to detect the airflow rate of the humidifying membrane 232. Both the wind sensor and the alarm are communicatively connected to the control device. When the wind sensor detects that the airflow rate of the humidifying membrane 232 is lower than a specified airflow rate, the control device controls the alarm to sound an alarm, prompting personnel to clean or perform a deep cleaning of the humidifying membrane 232.

[0105] The energy-saving humidifier 100 has three working modes, including humidification mode, cleaning mode, and deep cleaning mode.

[0106] Humidification mode: When the energy-saving humidifier 100 is turned on and in normal use, the water pump 221 supplies water to the top of the wet curtain 2321, and the fan assembly 24 drives the air through the wet curtain 2321, and the water evaporates to humidify the air.

[0107] Cleaning mode: The mobile drive unit 313 is activated, and the spray pipe 314 moves in a combined motion along the height direction Z and the width direction Y of the housing. During this process, the control valve 3192 is opened, and the cleaning agent mixed with water flows through the nozzle 317 to form a flat water curtain, which impacts the surface and micropores of the wet curtain 2321 from all directions; the water tank 21 collects the scale-containing wastewater and discharges it periodically.

[0108] Deep cleaning mode: First, stop the machine, then disconnect the connection between the water outlet of the water supply pipe 222 and the water inlet of the frame 231. Next, the lifting device 4 controls the humidification component 23 to rise, so that the height of the humidification component 23 along the height Z direction of the housing is higher than the height of the water tank 21 along the height Z direction of the housing. The humidification component 23 can then be removed using the handle 234. Finally, perform a deep cleaning of the humidification membrane 232 or replace it directly.

[0109] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection of the present invention. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of the present invention, or equivalent structural or procedural transformations made using the content of the present invention's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of patent protection of the present invention.
