[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, comprising the following steps:

[0021] S1. When the environment needs to be humidified, the motor is started to drive the rotating shaft and the driving gear to rotate synchronously, so that the driven gear drives the rotating rod to rotate, and then the worm drives the worm wheel to rotate, so that the threaded rod and the worm wheel rotate synchronously and drive the movable plate to move, thereby changing the deformation of the spring and the water inflow of the wet film;

[0022] S2. After adjustment, add water from the external water pipe to the water inlet chamber until the water pressure in the water inlet chamber is greater than the elastic force of the spring. At this time, the piston moves down 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 a period of water supply, the water pressure will decrease. At this time, the piston will move up and return to the upper pipe, and this reciprocating cycle will be used to achieve intermittent water supply.

[0023] S3. When the water flows into the water diversion trough, under the action of gravity, the water flows through the water diversion hole and falls onto the wet film to cover the wet film. After that, the fan drives the dry air to pass through the wet film and blow out from the air outlet, so that the humidity of the air increases and humid air is formed.

[0024] S4. While supplying water, the downward movement of the piston will drive the crank handle and the rocker to rotate through the pressure rod and the linkage rod, causing the water diversion rod to rotate synchronously around the fixed part. When excess water flows through the water diversion hole, it will flow down along the water diversion rod and be diverted through 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, the water supply system is provided with a connecting piece and a piston structure. When water is taken in, when the water pressure is greater than the elastic force of the spring, the piston moves down until it retreats into the middle tube. At this time, the water flow can fall into the water diversion trough through the lower tube. After a period of water supply, the water pressure will decrease. At this time, the piston will move up and return to the upper tube. In this way, intermittent water supply can be realized, thereby reducing the waste of water resources.

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

[0028] 3. In the present invention, by setting a water diversion structure, when supplying water, the downward movement of the piston will drive the crank and the rocker to rotate through the pressure rod and the linkage rod, so that the water diversion rod will rotate synchronously around the fixed part. When the piston moves up, it will rotate in the opposite direction. When excess water flows through the water diversion hole, it will flow down along the water diversion rod and be diverted through the water diversion rod to cover the wet film, so that the water flow can cover the wet film more evenly and quickly, and the fan can be used to blow towards the wet film to increase the humidity of the air.

[0044] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation modes.

[0045] Unless explicitly stated otherwise, throughout the specification, the term “comprise” or variations thereof such as “include” or “comprising” will be understood as including the stated elements or components but not excluding other elements or components.

[0046] Reference Figure 1-Figure 10 As shown, this embodiment provides a technical solution:

[0047] A water supply system for environmental humidity control comprises an outer box 1 and a fan 2 arranged on the rear side wall of the outer box 1. A horizontal partition plate 14 is arranged near the top of the outer box 1. A water inlet chamber 13 is formed between the partition plate 14 and the inner top surface of the outer box 1. A wet film assembly 4 is arranged in the outer box 1 in front of the fan 2. A water supply system 3 is arranged at the front side below the partition plate 14 and at a position corresponding to the position of the wet film assembly 4. The water supply system 3 supplies water to wet the wet film assembly 4. Then, dry air is blown out by the fan 2 to vaporize and evaporate the water molecules in the wet film assembly 4, thereby increasing the humidity of the air and forming humid air, thereby achieving the purpose of humidification. This is the basic principle of the 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, Figure 1-Figure 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 Figure 3-Figure 6As shown, an annular blocking plate 3211 is fixed at the inlet of the top surface of the upper tube 321. The blocking plate 3211 can prevent the piston 331 from being pushed out of the upper tube 321 under the action of the spring 333. The distribution range of the bottom end of the blocking plate 3211 is larger than the distribution range of the corresponding slide bar 332, so as to prevent the blocking plate 3211 from blocking the slide bar 332 from moving upward when the elastic force of the spring 333 is adjusted.

[0055] Specifically, the diameter of the lower half of the piston 331 is the same as the inner diameter of the upper tube 321, ensuring the sealing between the piston 331 and the upper tube 321. The diameter of the middle tube 322 is larger than the diameter of the upper tube 321. When the piston 331 retreats to the middle tube 322, water can flow into the middle tube 322.

[0056] In addition, a driving structure 31 for driving the adjustment structure 34 is provided in the outer box 1 at the rear side of the connecting piece 32. The driving structure 31 includes a motor 311 fixed to the outer wall of the right side of the outer box 1, a rotating shaft 312 coaxially fixed to the output shaft of the motor 311, and a plurality of active teeth 313 whose positions correspond to the number of the adjustment structure 34. The motor 311 drives the active teeth 313 to rotate synchronously through the rotating shaft 312, wherein the motor 311 can rotate in two directions;

[0057] Furthermore, the front end of the rotating rod 342 passes through the middle tube 322 and a driven tooth 343 is coaxially fixed to the front end, the driving tooth 313 is meshed with the corresponding driven tooth 343, and a front and rear horizontal rotating rod 342 is provided on the right side of the bottom surface of the movable plate 341, and a worm 344 is provided on the rotating rod 342 at a position corresponding to the position of the threaded rod 345, and the driving tooth 313 drives the rotating rod 342 to rotate through the driven tooth 343, thereby driving the worm 344 to rotate;

[0058] Furthermore, the top of the threaded rod 345 is embedded in the inner wall of the middle tube 322 and the two are rotatably connected. The movable plate 341 is provided with a threaded hole 3411 corresponding to the position of the threaded rod 345. The bottom end of the threaded rod 345 passes through the threaded hole 3411. The bottom end of the threaded rod 345 is coaxially fixedly connected with a worm gear 346. The worm gear 346 is meshed 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 to the threaded hole 3411, the movable plate 341 can be driven to slide up and down.

[0059] In addition, the side walls of the middle tube 322 are symmetrically provided with an extended outer frame 3221, and the front and rear ends of the movable plate 341 are arranged on the outer frame 3221. A limiting rod 3222 is provided between the upper and lower inner walls of the outer frame 3221. The limiting rod 3222 passes through the movable plate 341 and the two are slidably connected. By setting the limiting rod 3222, the movable plate 341 is prevented from rotating together with the threaded rod 345.

[0060] In addition, if Figure 7-10As shown, the wet film assembly 4 includes a mounting frame 41 and a wet film 42 arranged in the mounting frame 41. A water diversion groove 411 is arranged on the top surface of the mounting frame 41. A water diversion hole 412 is arranged at the bottom of the water diversion groove 411. The bottom of the water diversion groove 411 is high on the side close to the lower tube 323 and low on the side away from the lower tube 323. The diameter of the water diversion hole 412 is greater than the thickness of the wet film 42. When water is supplied, water flows through the lower tube 323 and falls into the water diversion groove 411. Under the action of gravity, water flows along the water diversion groove 411 and falls from the water diversion hole 412 to the wet film 42, and covers the wet film 42 under the action of gravity.

[0061] Furthermore, the water diversion structure 35 is arranged along the front and rear of the wet film 42 and is close to the wet film 42. A fixing piece 353 is arranged on the top surface of the water diversion rod 351. The top of the fixing piece 353 is fixed to the inner wall of the water diversion hole 412 at the corresponding position. The bottom end of the fixing piece 353 is rotatably connected to the top of the water diversion rod 351. The water diversion rod 351 can rotate around the bottom end of the fixing piece 353.

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

[0063] It should be noted that a circular plate with a diameter larger than that of the crank 355 is provided at the outer end of the crank 355 to prevent the crank 355 from being separated from the slide groove 3351. The front and rear water diversion structures 35 and the linkage rod 335 are centrally symmetrically distributed to ensure the uniformity of water flow distribution before and after 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, comprising the following steps:

[0065] 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 344 drives the worm wheel 346 to rotate, so that the threaded rod 345 and the worm wheel 346 rotate synchronously and drive the movable plate 341 to move, thereby changing the deformation 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 which time the piston 331 moves down until it retreats into the middle tube 322, and the water can flow through the lower tube 323 and fall into the water diversion groove 411. After a period of water supply, the water pressure will decrease, and the piston 331 will move up and back to the upper tube 321, and this reciprocating process is repeated to achieve intermittent water supply;

[0067] 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. After that, the fan 2 drives the dry air to pass through the wet film 42 and blow out from the air outlet 11, so that the humidity of the air increases and humid air is formed.

[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 rod 334 and the linkage rod 335, so that the water diversion rod 351 will rotate synchronously around the fixing part 353. When the excess water flows through the water diversion hole 412, it will flow down along the water diversion rod 351 and be diverted through the water diversion rod 352 to cover the wet film 42, so that the water flow coverage is more uniform.

These descriptions are not intended to limit the present invention to the precise form disclosed, and it is clear that many changes and variations can be made based on the above teachings.

10. A water supply method for environmental humidity control, using the water supply system for environmental humidity control according to any one of claims 1 to 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 (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 movement 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). Afterwards, 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.
