Technical Field

[0001] The utility model relates to the technical field of humidifiers, in particular to a fogless humidifier for a plant tissue culture room with a self - contained water purification device. Background Technique

[0002] During the process of plant tissue culture, the humidity in the culture room is a very important factor. Too low humidity may cause the culture medium to lose water and dry up or the osmotic pressure to increase, affecting the growth and differentiation of the cultured materials. Therefore, the humidifier dedicated to the plant tissue culture room plays a very important role.

[0003] The existing humidifiers in plant tissue culture rooms usually use household humidifiers. The laboratory environment, especially the plant tissue culture room, has very high requirements for humidity control. Household humidifiers usually do not have sufficient humidity control accuracy and cannot meet the strict requirements of the laboratory for a constant humidity environment. The commonly used ultrasonic technology in household humidifiers may produce powdery particle water mist, and these particles may affect the air quality in the laboratory, especially in a sterile experimental environment with extremely high requirements for air quality. In addition, the water tanks of some humidifiers are prone to breeding bacteria, and the bacteria falling on the tissue culture dishes or culture bottles may cause microbial contamination in the tissue culture room. The water tank of the household humidifier is small, and a tank of water is not enough to support the dry plant tissue culture room with the air conditioner running for 24 hours, and there is often a risk of dry burning.

[0004] Therefore, we propose a fogless humidifier for a plant tissue culture room with a self - contained water purification device to solve the problems raised above. Content of the Utility Model

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1-6 , the present invention provides a technical solution: a mist-free humidifier dedicated to a plant tissue culture room with a built-in water purification device, including: a water tank main body 1, a humidification box body 2, a water tank partition 7, and an external humidity detector 9. The water tank partition 7 is sealed and pressed on the upper end of the water tank main body 1, and the humidification box body 2 is arranged above the water tank partition 7;

[0033] A centrifugal fan 6 is fixedly installed on the lower surface of the top wall of the humidification box body 2. An air hole 23 is opened on the top wall of the humidification box body 2 for the centrifugal fan 6 to blow air outwards. A filter net 21 is opened on the side surface of the humidification box body 2, and the filter net 21 is used for filtering the incoming air.

[0034] A cation exchange column 3 is detachably arranged in the water tank main body 1 in a suspended manner. The resin filled in the cation exchange column 3 is a styrene-divinylbenzene copolymer with a sulfonic acid group functional group;

[0035] By opening the water tank main body 1 through the water tank partition 7, tap water can be poured into the water tank main body 1, and the tap water penetrates through the cation exchange column 3 to remove cations.

[0036] A water delivery pipe 4 is detachably arranged on the water tank partition 7. The water delivery pipe 4 eccentrically penetrates through the water tank partition 7. The lower part of the water delivery pipe 4 penetrates through the cation exchange column 3 and then inserts into the bottom of the water tank main body 1. The upper part of the water delivery pipe 4 inserts into the humidification box body 2. The water body after removing calcium and magnesium ions enters the water delivery pipe 4 through the pressure difference.

[0037] An antibacterial evaporation filter element 8 is arranged on the upper surface of the water tank partition 7 through a support column. A water storage tray 81 is arranged on the upper surface of the antibacterial evaporation filter element 8. The antibacterial evaporation filter element 8 includes an antibacterial evaporation filter screen. The water storage tray 81 is provided with mesh holes in contact with the antibacterial evaporation filter screen. The water storage tray 81 is connected to the water delivery pipe 4. Deionized water enters the water storage tray 81 through the water delivery pipe 4, and then the deionized water penetrates through the mesh holes on the water storage tray 81 to the antibacterial evaporation filter screen. At the same time, the centrifugal fan 6 rotates at a high speed to accelerate the air flow rate to increase the water vapor evaporation amount of the antibacterial evaporation filter screen. The evaporated gas enters the room through the air hole 23, thereby increasing the indoor air humidity.

[0038] A guide groove 72 is provided on the water tank partition 7. The plate body where the guide groove 72 is located is sloped. The excess deionized water on the antibacterial evaporation filter element 8 returns to the water tank body 1 through the guide groove 72. Symmetrical pressure equalizing holes 73 are also provided on the water tank partition 7 to balance the pressure of the water tank body 1 and the outside. An ultraviolet lamp 71 is provided on the lower surface of the water tank partition 7.

[0039] A touch display panel 22 is installed on one side of the humidification box 2, and the touch display panel 22 is connected to the central control system. The central control system controls and connects the ultraviolet lamp 71, the water level monitor 5, the main humidity detector 11, the centrifugal fan 6 and the water hardness detector 10. The central control system is wirelessly connected to the remote control device and the external humidity detector 9. The remote control device is a mobile phone in this embodiment, and the mobile phone app is used to remotely control the central control system, and the data of the central control system is uploaded to the mobile phone app;

[0040] The ultraviolet lamp 71 emits ultraviolet rays to kill bacteria, viruses and other microorganisms in the water, thereby improving the sanitation and safety of the water quality.

[0041] The water level monitor 5 is arranged at the bottom of the water tank body 1, below the cation exchange column 3, and the water level monitor 5 is composed of a water level monitoring probe, a data processing module, a communication module and an early warning module;

[0042] The water level monitoring probe senses subtle changes in the water level. When the water level is about to drop to the warning line, the data processing module receives the water level information from the water level monitoring probe and uses the communication module to synchronously transmit the water level information data to the humidifier early warning module and the central control system, thereby triggering the humidifier alarm and app push reminder.

[0043] The water hardness detector 10 is arranged at the bottom of the water tank body 1, and is used to detect the hardness of deionized water. The tap water flows through the cation exchange column 3, and the hardness of the water is detected by detecting the concentration of sodium ions in the outflowing water. Specifically, the tap water passes through the cation exchange resin containing sodium ions, and the resin is a styrene-ethylenediene benzene copolymer with a sulfonic acid functional group. The calcium and magnesium ions in the water are exchanged with the sodium ions on the resin. The total amount of calcium and magnesium ions in the water is calculated according to the change in the concentration of sodium ions before and after the exchange. When the sodium ion content in the deionized water is lower than the predetermined value, it is judged that the calcium and magnesium ions adsorbed by the cation exchange column 3 are saturated, and a signal is sent to the central control system, prompting that the cation exchange column 3 needs to be eluted and regenerated. If the deionized water still does not meet the standard after elution and regeneration, it is judged that the resin of the cation exchange column 3 is damaged and failed, and the central control system prompts to replace the cation exchange resin in the cation exchange column 3;

[0044] When the cation exchange column 3 is saturated with the cations in tap water, the water quality hardness detector 10 sends a signal to the central control system, and the app connected to the mobile phone will give an alarm reminder. Then, the cation exchange column 3 is taken out and replaced, and the saturated cation exchange column 3 is eluted with brine with a concentration of 10%. The brine is prepared by mixing softening salt with deionized water or pure water or distilled water.

[0045] The main body humidity detectors 11 are arranged on different outer walls of the water tank main body 1, and at least three are provided.

[0046] The external humidity detectors 9 are arranged at predetermined positions in the room, and at least one is provided.

[0047] Both the main body humidity detectors 11 and the external humidity detectors 9 are composed of a humidity detector module, a data processing module, a communication module, and a warning module.

[0048] The external humidity detectors 9 and the main body humidity detectors 11 respectively measure the humidity in different areas. The data processing module receives the real-time information from the humidity detectors in different areas, and the communication module synchronously transmits the data of the humidity information in different areas to the warning module of the humidifier. When the humidity has not reached the set value, the machine continues to work. When the humidity reaches the set value, the warning module triggers a reminder, and the machine automatically adjusts the wind force of the centrifugal fan 6 to keep the environmental humidity within the set range.

[0049] Working principle: In the shutdown state, remove the water tank partition 7 and the components above it, pour tap water into the water tank main body 1. The tap water penetrates through the cation exchange column 3 and becomes deionized water. The deionized water enters the water storage tray 81 at the top of the antibacterial evaporation filter through the water supply pipe 4 due to the upper and lower pressure difference. The deionized water penetrates the antibacterial evaporation filter through the holes in the water storage tray 81, and the excess deionized water flows back to the water tank main body 1 through the diversion groove 72 of the water tank partition 7 at the bottom of the antibacterial evaporation filter element 8.

[0050] Using the cold evaporation technology, the centrifugal fan 6 is used to accelerate the air flow rate to increase the water vapor evaporation amount of the antibacterial evaporation filter element 8, thereby increasing the air humidity.

[0051] When the cation exchange column 3 is saturated with the cations in tap water, the water quality hardness detector 10 sends a signal, indicating that the cation exchange column 3 needs to be eluted and regenerated.

[0052] The water level monitoring probe monitors the change of the water level. When the water level reaches the specified height, the data processing module receives the water level information from the water level monitoring probe, and uses the communication module to synchronously transmit the data of the water level information to the warning module and the central control system, thereby triggering an alarm and a push reminder to the remote mobile phone app.

[0053] The external humidity detector 9 and the main body humidity detector 11 respectively measure the humidity in different areas. The data processing module receives the real-time information from the humidity detectors in different areas. The communication module synchronously transmits the data of the humidity information in different areas to the central control system. When the humidity has not reached the set value, the machine continues to work. When the humidity reaches the set value, the warning module triggers a reminder, and the central control system automatically adjusts the rotation speed of the centrifugal fan 6 to reduce the wind force, reduce the evaporation amount, and keep the environmental humidity within the set range.

[0054] The content not detailedly described in this specification belongs to the prior art well-known to those skilled in the art.

[0055] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
