Description

Technical Field

[0001] The present invention belongs to the technical field of environmental humidity control, and specifically relates to a water supply system and a water supply method for environmental humidity control. Background Art

[0002] Whether in daily life or in some industrial productions, environmental humidity is particularly important. Appropriate humidity can make the human body comfortable, protect items or meet the humidity requirements of some specific industries.

[0003] For example, a fogless humidifier disclosed in the invention patent with the authorization announcement number CN118168075A in the technical field of humidifiers includes a casing and an air duct forming a hollow structure. Inside the air duct, a fan assembly, a humidifying assembly, and a water adding assembly are sequentially arranged along the air flow direction; the water adding assembly has a water outlet; the humidifying assembly includes a wet curtain bracket, a wet curtain, and a plurality of independently arranged water guiding channels. An inlet matching the water outlet is arranged in the central area at the top of the wet curtain bracket. One end of each of the plurality of water guiding channels communicates with the inlet, and the other end extends downward and obliquely to the top of the wet curtain and is evenly distributed, and the inclination angle of each water guiding channel is the same.

[0004] Combined with the above case and the actual situation, we found the following problems: In existing wet film humidifiers, water is mostly directly added and guided; during the water adding process, water is directly poured onto the wet film to wet it. However, due to the low evaporation rate and evaporation efficiency of the wet film humidifier, direct water supply is likely to cause the water flow to not be completely absorbed and evaporated by the wet film, resulting in a waste of water resources. At the same time, it is difficult to control the water volume directly and difficult to adjust the evaporation rate according to the actual situation. Summary of the Invention

[0020] On the other hand, the present invention also provides a water supply method for environmental humidity control. Using the above-mentioned water supply system for environmental humidity control, it includes the following steps:

[0021] S1. When it is necessary to humidify the environment, start the motor to drive the rotation of the rotating shaft and the driving gear synchronously, so that the driven gear drives the rotating rod to rotate. Then, drive the worm gear to rotate through the worm, so that the threaded rod rotates synchronously with the worm gear to drive the movable plate to move, thereby changing the deformation amount of the spring and changing the water inflow of the wet film.

[0022] S2. After adjustment, add water to the water inlet cavity from the external water pipe until the water pressure in the water inlet cavity is greater than the elastic force of the spring. At this time, the piston moves downward until it retreats into the middle pipe. At this time, the water flow can fall into the water diversion trough through the lower pipe. After supplying water for a period of time, the water pressure will decrease. At this time, the piston will move upward again and return to the upper pipe, and so on, to achieve intermittent water supply.

[0023] S3. When the water flow enters the water diversion trough, under the action of gravity, the water flow will pass through the water diversion holes and fall onto the wet film to cover the wet film. Then, drive the dry air to pass through the wet film by the fan and blow out from the air outlet, so that the humidity of the air increases to form moist air.

[0024] S4. While supplying water, the downward movement of the piston will drive the crank and the rocker to rotate through the pressing rod and the linkage rod, so that the water diversion rod rotates synchronously around the fixing member. When the excess water flow passes through the water diversion holes, it will flow down along the water diversion rod and be diverted by the water diversion rod to cover the wet film, making the water flow coverage more uniform.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0026] 1. In the present invention, in the water supply system, by providing a connecting member and a piston structure, when water is inlet, when the water pressure is greater than the elastic force of the spring, the piston moves downward until it retracts into the middle pipe. At this time, water can flow through the lower pipe and fall into the water diversion tank. After water supply for a period of time, the water pressure will decrease, and at this time, the piston will move upward back to the upper pipe, and so on, to achieve intermittent water supply. Intermittent water supply can be realized, reducing water resource waste.

[0027] 2. In the present invention, by providing an adjustment structure, the motor drives the rotating shaft and the driving gear to rotate synchronously, so that the driven gear drives the rotating rod to rotate. Then, the worm drives the worm wheel to rotate, causing the threaded rod to rotate synchronously with the worm wheel, thereby driving the movable plate to move, further changing the deformation amount of the spring, changing the water pressure threshold of the inlet water, and then adjusting the water supply frequency to make it more suitable for various usage environments.

[0028] 3. In the present invention, by providing a water diversion structure, when water is supplied, the downward movement of the piston will drive the rocker and the rocker arm to rotate through the pressure rod and the linkage rod, so that the water diversion rod rotates synchronously around the fixed member. When the piston moves upward, it rotates in the reverse direction. When the excess water flows through the water diversion hole, it will flow down along the water diversion rod and be diverted by the water diversion rod to cover the wet film, making the water flow coverage more uniform. The water can cover the wet film more evenly and quickly, and the fan is used to blow air towards the wet film to increase the humidity of the air. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The following will describe in detail the specific implementation manners of the present invention with reference to the drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation manners.

[0045] Unless otherwise clearly stated, throughout the specification, the term "comprising" or its variations such as "including" or "having" etc. will be understood to include the stated elements or components, without excluding other elements or other components.

[0046] Referring to Figures 1 - 10 as shown, this embodiment provides a technical solution:

[0047] A water supply system for environmental humidity control includes an outer box 1 and a fan 2 provided on the rear side wall of the outer box 1. A horizontal partition board 14 is provided at the top inside the outer box 1. The space between the partition board 14 and the inner top surface of the outer box 1 is a water inlet chamber 13. A wet film assembly 4 is provided in front of the fan 2 inside the outer box 1. A water supply system 3 is provided at the position corresponding to the wet film assembly 4 below and in front of the partition board 14. The wet film assembly 4 is wetted by the water supply from the water supply system 3, and then the dry air is blown by the fan 2 to vaporize and evaporate the water molecules in the wet film assembly 4, increasing the humidity of the air to form moist air, thereby achieving the purpose of humidification. This is the basic principle of a wet film humidifier and will not be elaborated here;

[0048] The water supply system 3 includes a plurality of regularly arranged connecting pieces 32, a piston structure 33 and an adjusting structure 34 arranged in the corresponding connecting pieces 32, and a water diversion structure 35 arranged in one-to-one correspondence with the piston structure 33;

[0049] The connecting piece 32 is composed of an upper tube 321, a middle tube 322 and a lower tube 323 from top to bottom. The top of the upper tube 321 passes through the dividing plate 14 and is connected to the water inlet chamber 13. The lower tube 323 is connected to the wet membrane assembly 4. During humidification, water can be supplied to the wet membrane assembly 4 through the water inlet chamber 13 and the connecting piece 32.

[0050] The piston structure 33 includes a piston 331 arranged in the corresponding upper tube 321, two sliding rods 332 symmetrically arranged front and back, and a spring 333 sleeved on the sliding rod 332. The sliding rod 332 passes through the piston 331 and the two are slidably connected. The center of the bottom surface of the piston 331 is fixedly connected with a pressing rod 334. When supplying water, when the water flow pressure is greater than the elastic force of the spring 333, the piston 331 will be pressed down. When the piston 331 is pressed into the middle tube 322, the upper tube 321 is completely opened, and the water flows down through the lower tube 323. After a period of water supply, the water pressure decreases, and the piston 331 will move up and back into the upper tube 321 under the elastic force of the spring 333 to block the upper tube again, thereby realizing intermittent water supply and reducing water resource waste.

[0051] The adjustment structure 34 includes a movable plate 341 and threaded rods 345 symmetrically arranged on the front and rear sides of the movable plate 341. The bottom end of the sliding rod 332 is fixedly connected to the top surface of the movable plate 341. The spring 333 is arranged between the corresponding piston 331 and the movable plate 341. By setting the adjustment structure 34, the initial elastic force of the spring 333 can be adjusted before water supply, thereby changing the threshold of water supply and changing the time when the water pressure reaches the threshold, that is, changing the water supply interval, thereby achieving the purpose of changing the water supply amount according to the ambient humidity;

[0052] The water diversion structure 35 includes a water diversion rod 351 and a plurality of water diversion rods 352 staggeredly fixed on the water diversion rod 351. By providing the water diversion structure 35, the falling water flow can cover the wet membrane assembly 4 more evenly and quickly.

[0053] Among them, Figures 1 - 2 As shown, an air outlet 11 is provided at the front side of the outer box 1 corresponding to the position of the wet membrane component 4, and a plurality of external water pipes 12 corresponding to the connecting piece 32 are provided on the rear side of the top surface of the outer box 1. The external water pipes 12 are connected to the water inlet cavity 13. The dry air blown out by the fan 2 passes through the wet membrane component 4 and then discharges the humid air through the air outlet 11, thereby changing the ambient humidity.

[0054] In addition, if Figures 3 - 6As shown in the figure, an annular baffle plate 3211 is fixed at the inlet on the top surface of the upper pipe 321. The baffle plate 3211 can prevent the piston 331 from being pushed out of the upper pipe 321 under the action of the spring 333. The distribution range of the bottom end of the baffle plate 3211 is larger than the distribution range of the corresponding slide rod 332, so as to prevent the baffle plate 3211 from blocking the upward movement of the slide rod 332 when adjusting the elastic force of the spring 333;

[0055] Specifically, the diameter of the lower half of the piston 331 is the same as the inner diameter of the upper pipe 321 to ensure the sealing performance between the piston 331 and the upper pipe 321. The diameter of the middle pipe 322 is larger than that of the upper pipe 321. When the piston 331 retracts into the middle pipe 322, water can flow into the middle pipe 322;

[0056] In addition, a driving structure 31 for driving the adjusting structure 34 is provided at the rear side of the outer box 1 inside the outer box 1. The driving structure 31 includes a motor 311 fixed on the right outer wall of the outer box 1, a rotating shaft 312 coaxially fixed to the output shaft of the motor 311, and a number of driving teeth 313 corresponding to the adjusting structure 34 in terms of position and quantity. The motor 311 drives the driving teeth 313 to rotate synchronously through the rotating shaft 312, and the motor 311 can rotate in two directions;

[0057] Furthermore, the front end of the rotating rod 342 passes through the middle pipe 322 and a driven tooth 343 is coaxially fixed to the front end of the rotating rod 342. The driving tooth 313 meshes with the corresponding driven tooth 343. A horizontally front-back rotating rod 342 is provided on the bottom surface of the movable plate 341 near the right side. A worm 344 is provided on the rotating rod 342 at a position corresponding to the threaded rod 345. The driving tooth 313 drives the rotating rod 342 to rotate through the driven tooth 343, and then drives the worm 344 to rotate;

[0058] Furthermore, the top end of the threaded rod 345 is embedded in the inner wall of the middle pipe 322 and the two are rotatably connected. A threaded hole 3411 corresponding to the threaded rod 345 is provided on the movable plate 341. The bottom end of the threaded rod 345 passes through the threaded hole 3411 and a worm gear 346 is coaxially fixed to the bottom end of the threaded rod 345. The worm gear 346 meshes with the corresponding worm 344. When the worm 344 rotates, the threaded rod 345 can be driven to rotate through the worm gear 346. Since the threaded rod 345 is threadedly connected with the threaded hole 3411, the movable plate 341 can be driven to slide up and down;

[0059] In addition, outwardly extending outer frames 3221 are symmetrically provided on the front and rear sides of the side wall of the middle pipe 322. The front and rear ends of the movable plate 341 are arranged in the outer frames 3221. A limiting rod 3222 is provided between the upper and lower inner walls of the outer frames 3221. The limiting rod 3222 passes through the movable plate 341 and the two are slidably connected. By providing the limiting rod 3222, the movable plate 341 is prevented from rotating together with the threaded rod 345.

[0060] In addition, as Figures 7 - 10As shown in the figure, the wet film assembly 4 includes a mounting frame 41 and a wet film 42 disposed within the mounting frame 41. The top surface of the mounting frame 41 is provided with a water diversion trough 411. The bottom of the water diversion trough 411 is provided with a water diversion hole 412. The bottom of the water diversion trough 411 is higher on the side close to the lower pipe 323 and lower on the side away from the lower pipe 323. The diameter of the water diversion hole 412 is greater than the thickness of the wet film 42. When water is supplied, the water flows through the lower pipe 323 and falls into the water diversion trough 411, and under the action of gravity, it flows along the water diversion trough 411 and falls from the water diversion hole 412 onto the wet film 42, and covers the wet film 42 under the action of gravity;

[0061] Further, the water diversion structure 35 is provided both in front of and behind the wet film 42 and is in close contact with the wet film 42. The top surface of the water diversion rod 351 is provided with a fixing member 353. The top end of the fixing member 353 is fixed to the inner wall of the corresponding water diversion hole 412, and the bottom end of the fixing member 353 is rotatably connected to the top end of the water diversion rod 351. The water diversion rod 351 can rotate around the bottom end of the fixing member 353;

[0062] In addition, the pressing rod 334 is integrally in the shape of a tuning fork. A linkage rod 335 is fixed to the side wall of the bottom end of the pressing rod 334. A left - right horizontal sliding groove 3351 is provided on the linkage rod 335. The top end of the water diversion rod 351 is fixedly connected to the outside in a left - right horizontal direction with a rocker 354. The other end of the rocker 354 is fixed with a crank 355. The outer end of the crank 355 extends into the sliding groove 3351 and is slidably connected to the sliding groove 3351. When water is supplied, the piston 331 moves downward, thereby driving the pressing rod 334 to press downward. Since the crank 355 is slidably connected to the sliding groove 3351, the pressing rod 334 drives the crank 355 to rotate, and drives the water diversion rod 351 to rotate around the fixing member 353 through the rocker 354, thereby dispersing the water flow, so that the water flow can be more quickly and evenly dispersed on the surface of the wet film 42;

[0063] It should be noted that the outer end of the crank 355 is provided with a circular plate having a diameter larger than that of the crank 355 to prevent the crank 355 from disengaging from the sliding groove 3351. The front - rear water diversion structures 35 and the linkage rod 335 are symmetrically distributed about the center to ensure the uniformity of the water flow distribution on both sides of the wet film 42.

[0064] The present invention also provides a water supply method for environmental humidity control. Using the above - mentioned water supply system for environmental humidity control, it includes the following steps:

[0065] S1. When it is necessary to humidify the environment, start the motor 311 to drive the rotating shaft 312 and the driving gear 313 to rotate synchronously, so that the driven gear 343 drives the rotating rod 342 to rotate, and then drives the worm gear 346 to rotate through the worm 344, so that the threaded rod 345 rotates synchronously with the worm gear 346, thereby driving the movable plate 341 to move, and then changing the deformation amount of the spring 333 and changing the water inflow of the wet film 42;

[0066] S2. After adjustment, water is added to the water inlet chamber 13 from the external water pipe 12 until the water pressure in the water inlet chamber 13 is greater than the elastic force of the spring 333. At this time, the piston 331 moves downward until it retracts into the middle pipe 322. At this time, the water flow can fall into the water guiding groove 411 through the lower pipe 323. After supplying water for a period of time, the water pressure will decrease. At this time, the piston 331 will move upward again and return to the upper pipe 321, and so on, to achieve intermittent water supply;

[0067] S3. When the water flow enters the water guiding groove 411, under the action of gravity, the water flow will pass through the water guiding hole 412 and fall onto the wet film 42 to cover the wet film 42. Then, the fan 2 drives the dry air to pass through the wet film 42 and blow out from the air outlet 11, increasing the humidity of the air and forming moist air;

[0068] S4. While supplying water, the downward movement of the piston 331 will drive the crank 355 and the rocker 354 to rotate through the pressure lever 334 and the linkage rod 335, so that the water guiding rod 351 rotates synchronously around the fixing member 353. When the excess water flow passes through the water guiding hole 412, it will flow down along the water guiding rod 351 and be diverted by the water dividing rod 352 to cover the wet film 42, making the water flow coverage more uniform.

[0069] The foregoing description of the specific exemplary embodiments of the present invention is for purposes of illustration and exemplification. These descriptions are not intended to limit the invention to the precise forms disclosed, and it is apparent that many changes and variations are possible in light of the above teaching.

10. A water supply method for environmental humidity control, using the water supply system for environmental humidity control according to claim 9, characterized in that: The following steps are involved: S1. When the environment needs to be humidified, the motor (311) is started to drive the rotating shaft (312) and the driving gear (313) to rotate synchronously, so that the driven gear (343) drives the rotating rod (342) to rotate, and then the worm gear (346) is driven to rotate through the worm gear (344), so that the threaded rod (345) and the worm gear (346) rotate synchronously, thereby driving the movable plate (341) upward, thereby compressing the spring (333), changing the water pressure threshold of water supplied from the connecting piece (32) to the water guide groove (411) and then flowing into the wet membrane (42), thereby adjusting the frequency of water supply; S2, after adjustment, water is added to the water inlet chamber (13) from the external water pipe (12) until the water pressure in the water inlet chamber (13) is greater than the elastic force of the spring (333), at which time the piston (331) moves downward until it retreats into the middle tube (322), and the water can flow through the lower tube (323) into the water diversion trough (411). After a period of water supply, the water pressure will decrease, and the piston (331) will move upward back to the upper tube (321), and this reciprocating process is repeated to achieve intermittent water supply; S3. After the water flows into the water inlet groove (411), under the action of gravity, the water flows through the water inlet hole (412) and falls onto the wet film (42) to cover the wet film (42). Thereafter, the fan (2) drives the dry air to pass through the wet film (42) and blow it out from the air outlet (11), thereby increasing the humidity of the air and forming humid air. S4. While supplying water, the piston (331) moves downward, which drives the crank (355) and the rocker (354) to rotate through the pressure rod (334) and the linkage rod (335), thereby causing the water diversion rod (351) to rotate synchronously around the fixing member (353). When excess water flows through the water diversion hole (412), it flows down along the water diversion rod (351) and is diverted through the water diversion rod (352) to cover the wet film (42), so that the water flow covers more evenly.
