Description

Technical Field

[0001] This invention relates to the field of bean sprout growing device technology, specifically a household bean sprout growing device. Background Technology

[0002] Bean sprouts are a common food ingredient known for their rich nutrition and tender texture. Due to their short production cycle and low cost, they have become a popular choice for everyday family meals. Traditional home cultivation of bean sprouts often involves manual methods, such as soaking beans in containers and regularly watering and changing the water. This not only requires frequent manual intervention but also easily leads to the following problems:

[0003] 1) Improper water control: Manual watering can easily lead to too much water (causing beans to rot) or too little water (affecting germination rate), and it is impossible to achieve uniform watering. Some beans will grow poorly due to lack of water or water accumulation. The operation is cumbersome and increases the burden of cleaning.

[0004] 2) Limited functionality: Traditional devices cannot adjust the texture of bean sprouts according to needs (such as crisp or soft), which is not suitable for the diverse and convenient needs of modern families. Summary of the Invention

[0068] A pump is installed inside the base 100. The inlet of the pump is connected to the first water outlet 105, and the other end of the pump is connected to the installation pipe 104. The pump draws water from the water storage chamber 102 and delivers it upward through the installation pipe 104.

[0069] The germination bucket 200 has a placement trough 201. The bottom of the placement trough 201 is not closed and is connected to the water storage chamber 102. A draining tray 203 and a seedling tray rack 204 are placed in the placement trough 201, and the seedling tray rack 204 is placed above the draining tray 203.

[0070] The bottom of the drain tray 203 is provided with a limiting ridge 205, and the lower part of the inner cavity of the placement groove 201 is provided with an inwardly protruding limiting ring. The drain tray 203 is installed at the bottom of the placement groove 201, and the limiting ridge 205 of the drain tray 203 abuts against the upper part of the limiting ring. The limiting ring prevents the drain tray 203 from falling downward.

[0071] The seedling tray rack 204 includes an extension base 206 and a seedling tray 207. The seedling tray 207 is positioned above the extension base 206, and multiple telescopic rods 208 are provided between the seedling tray 207 and the extension base 206 to adjust the height. The seedling tray rack 204 is placed above the draining tray 203, and seedling tray racks 204 can be stacked on top of the seedling tray rack 204, or it can be left empty and used as a pressure tray.

[0072] The telescopic rod 208 is equipped with a locking bolt 210. The telescopic rod 208 changes the distance between the seedling tray 207 and the extension base 206 by telescopic movement, and is then locked and fixed by the locking bolt 210.

[0073] The bottom of the telescopic rod 208 is inserted into the extension base 206. Fixing bolts 209 are installed on the extension base 206 near the telescopic rod 208. The fixing bolts 209 are screwed inward to fix the extension base 206 and the telescopic rod 208 together. The seedling tray 207 can be separated from the extension base 206 by removing the fixing bolts 209.

[0074] The seedling tray 207 has a uniform grid and a horizontal bar for limiting the position. The beans are evenly spread on the grid, and the horizontal bar divides the grid into multiple areas.

[0075] Both the draining tray 203 and the seedling tray 207 have through holes in the middle for inserting the connecting pipe 407.

[0076] The top of the germination bucket 200 is provided with a cover plate 300, and a bolt handle 302 is installed in the middle of the top of the cover plate 300. A screw is provided at the bottom of the bolt handle 302 and the screw extends downward. An air filter 301 is installed on one side of the top of the cover plate 300. The air filter 301 is responsible for the air exchange in the germination bucket 200. The air filter 301 draws out the air in the germination bucket 200 and filters it to reduce the spread of odors.

[0077] The cover plate 300 has symmetrically arranged connecting rods 303 around its four edges. The connecting rods 303 are equipped with adjusting nuts 304. Rotating the adjusting nuts 304 can adjust the downward extension length of the connecting rods 303. The top four corners of the germination bucket 200 have downwardly recessed fixing grooves 202, and the fixing grooves 202 have connecting holes in the middle.

[0078] The connecting rod 303 is inserted downward into the connecting hole of the fixing groove 202, and the adjusting nut 304 is placed in the fixing groove 202;

[0079] The distance between the cover plate 300 and the germination bucket 200 is changed by adjusting the nut 304, and the gap between the cover plate 300 and the germination bucket 200 is used as an air exchange channel;

[0080] A sprinkler tray frame 400 is installed below the cover plate 300. The sprinkler tray frame 400 includes a sprinkler tray 401, a fixing seat 402 and a connecting rod 403. The top of the fixing seat 402 is provided with an upwardly extending screw seat. The screw seat has a screw hole. The screw at the bottom of the bolt handle 302 is installed downward in the screw seat to install the sprinkler tray frame 400 and the cover plate 300 together. The spraying distance between the sprinkler tray frame 400 and the germination bucket 200 can also be adjusted by rotating the bolt handle 302.

[0081] A connecting pipe 407 is installed at the bottom of the fixed base 402. The bottom of the connecting pipe 407 is connected downward to the mounting pipe 104. The connecting pipe 407 supplies water to the sprinkler tray frame 400. The inner cavity of the fixed base 402 is connected to the connecting pipe 407 and the connecting rod 403.

[0082] A connecting rod 403 is symmetrically arranged around the fixed base 402. Multiple rings of sprinkler discs 401 are installed on the connecting rod 403. A sprinkler channel 406 is opened in the connecting rod 403. The sprinkler channel 406 connects the fixed base 402 and the sprinkler disc 401, and guides the water flow in the connecting pipe 407 into the sprinkler disc 401.

[0083] The bottom of the sprinkler plate 401 is evenly provided with sprinkler screw holes 405. A micro water drip head 404 is screwed onto the sprinkler screw hole 405. The micro water drip head 404 includes nozzles with various opening diameters and solid plug nozzles. The solid plug nozzles are used to plug the sprinkler screw holes 405.

[0084] The connecting pipe 407 includes upper and lower sections. The lower section of the connecting pipe 407 is provided with a screw connector 408, and the inner cavity at the end of the upper section of the connecting pipe 407 is provided with a threaded wall. The upper and lower sections of the connecting pipe 407 are connected to the threaded wall through the screw connector 408.

[0085] A filter layer 409 is provided in the inner cavity of the lower connecting pipe 407. The filter layer 409 filters the upward water flow, reduces the carrying of impurities, and improves the purity of the spray water.

[0086] A tilting device 600 is installed in the middle of the inner cavity of the germination bucket 200. The tilting device 600 receives the water flow sprayed by the sprinkler tray 400 and tilts it after the water flow accumulates to a certain extent to complete the irrigation.

[0087] The tilting device 600 includes multiple tilting boxes 601 and a rotating rod 602. The tilting box 601 is sleeved on the rotating rod 602. Both ends of the rotating rod 602 are inserted into the germination bucket 200 and extend outward. Both ends of the rotating rod 602 are provided with threaded sections, and limit nuts 603 are installed on the threaded sections. The limit nuts 603 are located on the outer side of the germination bucket 200, so that the rotating rod 602 will not come off while rotating.

[0088] The pouring box 601 is an inverted "convex" shape. The rotating rod 602 is inserted into the lower middle part of the pouring box 601. The bottom of the inner cavity of the pouring box 601 is provided with an upwardly protruding water-dividing ridge 604. The inner cavity of the pouring box 601 has a biased structure. When water is stored in the pouring box 601, one side is biased. Under the action of gravity, the pouring box 601 tilts to one side and then pours out the water inside to water the beans. This can achieve intermittent watering.

[0089] The bottom of the pouring box 601 is provided with an inverted cone-shaped balance block 605. After the water is poured out of the pouring box 601, it returns to its initial state under the action of the balance block 605 and receives the water again.

[0090] To achieve intermittent irrigation, the micro-drip irrigation head 404 can be adjusted. For example, the micro-drip irrigation head 404 above the pouring box 601 can be replaced with a micro-drip irrigation head 404 with the same opening diameter, while the micro-drip irrigation heads 404 not located in the pouring box 601 can be replaced with solid blockage nozzles to improve the utilization rate of water flow.

[0091] In addition, after disassembling the tilting device 600, all micro-water drip irrigation heads 404 can be installed as flowable micro-water drip irrigation heads 404 to achieve all-round spraying; micro-water drip irrigation heads 404 of different diameters can also be installed in different positions; for example, the micro-water drip irrigation heads 404 near the fixed base 402 use a smaller opening diameter, while the micro-water drip irrigation heads 404 far from the fixed base 402 use a larger opening diameter. By limiting the irrigation flow at different positions by the opening diameter, balanced spraying at different positions can be achieved;

[0092] Depending on the desired texture of the bean sprouts, you can choose the appropriate watering method. For example, when you choose direct spraying, the bean sprouts can absorb more water, their cells will swell excessively, their tissue structure will be loose, and the bean sprouts will have larger and softer roots, making them suitable for stewing.

[0093] The intermittent irrigation method using the 600-pour device allows for intermittent water flow. The beans absorb water intermittently and have a digestion time, resulting in a moderate cell expansion rate and smaller bean sprouts with a crisp and tender texture, suitable for stir-frying. Through flexible selection, it is possible to cultivate bean sprouts with various textures, which is very convenient.

[0094] A water-passing device 500 is provided on the rear side of the base 100, which is responsible for filtering and draining the water that has been used multiple times in the water storage chamber 102, and injecting new water into the water storage chamber 102.

[0095] The water conveying device 500 includes a mounting bracket 501, a housing 502, an inlet pipe 503, and an outlet pipe 504. The base 100 has a mounting groove on its rear side, and the mounting bracket 501 is fixed in the mounting groove. The housing 502 is installed in the middle of the mounting bracket 501, and the inlet pipe 503 and the outlet pipe 504 are installed at the bottom of the mounting bracket 501.

[0096] The housing 502 is equipped with a bidirectional pump 505 and a switching valve 506. One end of the bidirectional pump 505 is connected to the second water outlet 106, and the other end of the bidirectional pump 505 is connected to the switching valve 506. The switching valve 506 is connected to the inlet pipe 503 and the outlet pipe 504.

[0097] An extension pipe is provided at one end of the inlet pipe 503. The extension pipe extends outward and is installed on a faucet (or other water source) via an adapter. The extension pipe introduces water into the inlet pipe 503. An inlet valve 507 is installed at the connection between the inlet pipe 503 and the extension pipe. A flow monitor 510 is installed on the inlet valve 507. A pressure reducing check valve 508 is installed at the connection between the inlet valve 507 and the inlet pipe 503.

[0098] A connecting valve 509 is installed at the other end of the water inlet pipe 503. The connecting valve 509 is connected to the switching valve 506 through a pipe. The water inlet pipe 503 is connected to tap water to provide new water flow to the water storage chamber 102.

[0099] A filter inner cylinder 511 is provided in the inner cavity of the water outlet pipe 504. A flow cavity 512 is reserved between the filter inner cylinder 511 and the inner cavity of the water outlet pipe 504. A pipe port valve 514 is installed at one end of the water outlet pipe 504 near the switching valve 506, and the pipe port valve 514 is connected to the switching valve 506 through a pipe.

[0100] The other end of the water outlet pipe 504 is equipped with a drain valve 513, which is connected to the flow chamber 512. The outer end of the drain valve 513 is equipped with a drain pipe that extends to the drain outlet of the sink for discharging wastewater.

[0101] Clean water is introduced into the inlet pipe 503 and then injected into the water storage chamber 102 through the switching valve 506 and the two-way pump 505. When it is necessary to discharge the water in the water storage chamber 102, the switching valve 506 switches the flow path to the outlet pipe 504 and injects the sewage into the filter inner cylinder 511 of the outlet pipe 504. The sewage is filtered through the permeation of the filter membrane. The filtered water permeates into the flow chamber 512 and is discharged through the discharge valve 513, which can reduce sewage and odor.

[0102] A threaded sleeve is provided at the end of the water outlet pipe 504 away from the discharge valve 513. The threaded sleeve is installed on one side of the water outlet pipe 504. The filter inner cylinder 511 can be removed and replaced by opening the threaded sleeve. The filter inner cylinder 511 has outwardly protruding support ribs at both ends, and the other end of the support ribs abuts against the inner wall of the flow cavity 512.

[0103] Working principle: The device consists of two parts: a base 100 and a germination bucket 200, which are installed by splicing. The base 100 and the germination bucket 200 are fixed by splicing groove 103 and splicing edge, ensuring that the two are tightly connected. At the same time, the sealing cover at the bottom of the germination bucket 200 can prevent water leakage.

[0104] The draining tray 203 and the seedling tray frame 204 inside the germination bucket 200 are fixed in position by the limiting ring and the limiting ridge 205, forming a vertical structure of seedling layer-draining layer-water storage layer, which not only ensures the stability of the beans, but also realizes water circulation.

[0105] Water supply and circulation system: Water storage chamber 102 is used to store clean water, and water supply device 500 is responsible for water replenishment and drainage;

[0106] When water is introduced, tap water is injected into the water storage chamber 102 through the inlet pipe 503, switching valve 506 and bidirectional pump 505. Pressure reducing check valve 508 can prevent water backflow, and flow monitor 510 monitors the water inflow.

[0107] When draining, the sewage in the water storage chamber 102 enters the filter inner cylinder 511 of the outlet pipe 504 through the second water outlet 106 and the bidirectional pump 505 to filter impurities, and then is discharged through the discharge valve 513 to reduce odor.

[0108] The pump inside the base 100 draws water from the water storage chamber 102 through the first water outlet 105, and then transports it upward to the sprinkler tray frame 400 through the installation pipe 104 and the connecting pipe 407. The water after spraying continues to collect downward in the water storage chamber 102, and is continuously transported by the pump. The filter layer 409 in the connecting pipe 407 filters the upward water flow to ensure the purity of the spray water. The first water outlet 105 is equipped with a filter screen, which can block large particles of impurities when the water flows through. The second water outlet 106 adopts a large-diameter water passage hole, and impurities are transported through the pipeline to the water passing device 500 for filtration.

[0109] The sprinkler tray frame 400 delivers water to multiple sprinkler trays 401 via the connecting rod 403, and then sprays it out through the micro-water drip head 404 to achieve two irrigation modes: The first mode is that after the tilting device 600 is disassembled, all micro-water drip heads 404 are turned on, and the water flow is sprayed directly onto the beans in the seedling tray 207, which is suitable for soft and tender bean sprouts that require more moisture; the micro-water drip head 404 can be replaced with different diameter or solid plug nozzles to flexibly adjust the spray range and water volume to adapt to the irrigation needs of different locations, such as using large diameter nozzles at the edges to ensure a balanced water volume;

[0110] The second method involves retaining the tilting device 600, while the micro-drip irrigation head 404 supplies water only to the tilting box 601. After water accumulates, the tilting box 601 automatically tilts to pour water due to the shift in its center of gravity, completing intermittent irrigation. This method is suitable for tender bean sprouts with moderate moisture and a compact structure. The balance block 605 of the tilting device ensures that the tilting box 601 automatically resets after pouring water, continuously receiving the water flow and realizing automated intermittent irrigation.

[0111] Excess water leaks through the mesh of the seedling tray 207 to the drain tray 203, and then flows back to the water storage chamber 102 through the opening at the bottom of the placement trough 201, forming a water cycle;

[0112] The telescopic rod 208 of the seedling tray frame 204 can adjust the height of the seedling tray 207 to adapt to the height changes during the growth process of different bean sprouts, avoid squeezing, and improve the germination rate;

[0113] The air filter 301 of the cover plate 300 enables air exchange within the germination chamber 200 and filters odors; the gap between the cover plate 300 and the germination chamber 200 can be controlled by adjusting the nut 304 to balance ventilation and humidity.

It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or basic characteristics.
