Description

Technical Field

[0001] The present application relates to the technical field of humidifiers, and in particular to a fog-free humidification module for a micro-inkjet printing system. Background Art

[0002] In the existing micro-inkjet printing system, some printing materials with special requirements for the environment are often affected by the ambient temperature and humidity. In view of the specific ambient temperature and humidity requirements, the equipment needs to be able to adjust the ambient temperature and humidity in time.

[0003] As for the humidity control problem, the current humidifier is mainly adjusted manually. There are certain drawbacks in its production management, and manual operation is bound to make mistakes, resulting in distortion of relevant parameters. Humidifiers are mainly divided into ultrasonic humidifiers and thermal evaporation humidifiers. Among them, ultrasonic humidifiers use ultrasonic high-frequency oscillation to break up the water body into water mist particles, and then bring them into the indoor air through components such as fans to achieve the purpose of humidification. This ultrasonic humidifier will produce a large amount of visible water mist when working, and will cause white mist on the surface of surrounding objects and even wet the electrical equipment in the micro-inkjet printing system. The thermal evaporation humidifier vaporizes the water body to produce steam by electric heating. It is the safest, most effective, energy-saving and environmentally friendly, and has a large humidification capacity. Therefore, the application demand for fog-free humidification humidifiers is increasing. In addition, the current humidification methods are mostly global humidification, which may affect some electrical equipment in the micro-inkjet printing system.

[0004] As for the temperature control problem, the temperature is currently mainly adjusted by desktop air conditioners. The temperature adjustment process is manually operated, the indoor space is large, and the temperature change is not adjusted in time, resulting in a large deviation between the actual value and the preset value. For example, the tolerance of the operating conditions is exceeded, resulting in the working environment not meeting the standards and the printed products mutating. This not only increases production costs, but also causes problems such as waste of resources and low production efficiency. Utility Model Content

[0037] The exemplary embodiments of the present application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present application, and are not intended to exhaust all possible methods of the present application, nor to limit the scope of the present application.

[0038] The present application provides a fog-free humidification module, which can be used, for example, in a micro-inkjet printing system to control the ambient temperature and humidity of printing materials with special environmental requirements. Of course, the fog-free humidification module can also be used in other occasions.

[0039] See also Figures 1 to 3 The mistless humidification module provided in the embodiment of the present application may include a wet film evaporator 100, a liquid heat exchanger 210, a gas heat exchanger 310, a liquid delivery device 220, and a gas delivery device 320. The liquid heat exchanger 210 is used to adjust the temperature of the liquid entering the wet film evaporator 100, and the gas heat exchanger 310 is used to adjust the temperature of the gas entering the wet film evaporator 100. The liquid delivery device 220 is used to control the liquid to enter the wet film evaporator 100, and the gas delivery device 320 is used to control the gas to pass through the wet film evaporator 100.

[0040] It can be understood that the wet film evaporator 100 is a prior art, and its principle is that when unsaturated air flows through the wet film evaporator 100, the water molecules in the wet film evaporator 100 absorb the heat of the air and vaporize and evaporate, so that the humidity of the air increases and the temperature decreases, which plays a role in regulating the humidity and temperature of the environment. At the same time, the air in the environment can also be filtered through the wet film evaporator 100. The present application realizes fog-free humidification by using the wet film evaporator 100, which is safe, effective, energy-saving and environmentally friendly, and has a large humidification capacity.

[0041] Furthermore, the liquid heat exchanger 210 and the gas heat exchanger 310 of the present application are integrated into the fog-free humidification module, and more temperature and humidity control requirements can be met by adjusting the working states of the liquid heat exchanger 210, the gas heat exchanger 310, the liquid delivery device 220, and the gas delivery device 320. For example, controlling the liquid heat exchanger 210 to increase the temperature of the liquid can speed up the humidification rate, controlling the gas heat exchanger 310 to increase the temperature of the gas can increase the ambient temperature, and increasing the temperature of the liquid and gas at the same time can achieve thermal humidification, etc. (see below for specific adjustment methods). The equipment has a high degree of integration and few requirements for the equipment installation environment, which makes it easy to quickly deploy it in the application scenario.

[0042] Compared with the global humidification form of laboratories and factories in the prior art, the fog-free humidification module provided in the present application belongs to local humidification, which can prevent humidity from affecting some electrical equipment in, for example, a micro-inkjet printing system.

[0043] In one embodiment of the present application, the liquid delivery device 220 can be a pump, etc. When the liquid delivery device 220 is turned on, the humidification function can be realized; when the liquid delivery device 220 is turned off, the fog-free humidification module can also realize simple air filtration and circulation functions, and adjust the ambient temperature under the action of the gas heat exchanger 310. The gas delivery device 320 can be a fan, etc. After the gas delivery device 320 is turned on, the corresponding humidification and / or temperature adjustment functions can be performed. After the gas delivery device 320 is turned off, the humidification and temperature adjustment can be stopped.

[0044] The liquid heat exchanger 210 and the gas heat exchanger 310 can be set to an electric heating mode, and the working state of the fog-free humidification module can be controlled by the on and off state. For example, the corresponding relationship between the working state of the fog-free humidification module and the corresponding device switch can include the following examples.

[0045] (1) Air circulation: the liquid heat exchanger 210 is turned off, the liquid delivery device 220 is turned off, the gas heat exchanger 310 is turned off, and the gas delivery device 320 is turned on.

[0046] (2) Heating and drying: the liquid heat exchanger 210 is turned off, the liquid conveying device 220 is turned off, the gas heat exchanger 310 is turned on, and the gas conveying device 320 is turned on.

[0047] (3) Thermal humidification: the liquid heat exchanger 210 is turned on, the liquid delivery device 220 is turned on, the gas heat exchanger 310 is turned on, and the gas delivery device 320 is turned on.

[0048] (4) Cold humidification: the liquid heat exchanger 210 is turned off, the liquid delivery device 220 is turned on, the gas heat exchanger 310 is turned off, and the gas delivery device 320 is turned on.

[0049] (5) Rapid humidification: the liquid heat exchanger 210 is turned on, the liquid delivery device 220 is turned on, the gas heat exchanger 310 is turned off, and the gas delivery device 320 is turned on.

[0050] It can be understood that in the (5) rapid humidification working state, the liquid heat exchanger 210 heats the liquid, which can promote the vaporization of the liquid to generate steam, improve the humidification efficiency, and achieve the purpose of "rapid".

[0051] It can be understood that when the liquid heat exchanger 210 and the gas heat exchanger 310 in the above five working states are heat exchangers capable of heating or cooling, the above "on" can correspond to heating, and "off" can correspond to not working. Of course, it is also possible to achieve a temperature and humidity adjustment mode such as cooling and drying by, for example, cooling the air passing through the gas heat exchanger 310, and not working the liquid heat exchanger 210 and the liquid delivery device 220.

[0052] In one embodiment of the present application, see Figure 1 and Figure 3, the fog-free humidification module may include an air inlet 410, a first sensor 510, an air outlet 420, and a second sensor 520. The air inlet 410 is connected to the wet film evaporator 100, and the first sensor 510 is used to monitor the temperature and humidity of the gas entering the air inlet 410. The wet film evaporator 100 is connected to the air outlet 420, and the second sensor 520 is used to monitor the temperature and humidity of the gas after passing through the wet film evaporator 100. Among them, the first sensor 510 can be an integrated temperature and humidity sensor, or the first sensor 510 includes a temperature sensor and a humidity sensor. The second sensor 520 is the same. Figure 3 In the figure, the black arrows indicate the direction of gas inlet and outlet. Figure 1 In the figure, the “×” at the air inlet 410 indicates that the air is entering perpendicular to the paper plane, and the “·” at the air outlet 420 indicates that the air is passing perpendicular to the paper plane. Figure 1 The components indicated by the air inlet 410 and / or the air outlet 420 in the figure have a perspective relationship in the figure, and the air inlet and outlet directions thereof can also be adaptively adjusted.

[0053] In one embodiment of the present application, the fog-free humidification module may include a control module, the first sensor 510 and the second sensor 520 may be connected to the control module and transmit detection signals to the control module, the liquid heat exchanger 210, the gas heat exchanger 310, the liquid delivery device 220 and the gas delivery device 320 are connected to the control module and controlled by the signal of the control module, so as to be able to timely and comprehensively control the working state of the fog-free humidification module and provide suitable temperature and humidity for, for example, a micro-inkjet printing system.

[0054] In one embodiment of the present application, see Figure 1 and Figure 2 The wet film evaporator 100 includes a wet film body 110, and the membrane surface of the wet film body 110 is arranged horizontally. The liquid entering the wet film evaporator 100 passes downward through the membrane surface (such as Figure 2 As shown in FIG. 1 ), the gas entering the wet film evaporator 100 passes upward through the membrane surface (as shown in FIG. Figure 1 shown).

[0055] It can be understood that the liquid generally enters from the top of the wet membrane body 110. When the membrane surface is set vertically, the liquid flows on the membrane surface in the up-down direction, and the gas passes through the membrane surface in the horizontal direction. The liquid at each position of the membrane surface is unevenly distributed, and the liquid flow direction is roughly perpendicular to the gas flow direction, and the contact is not sufficient. However, in this embodiment of the present application, the membrane surface is set horizontally, the liquid passes through the membrane surface from top to bottom, and the gas passes through the membrane surface from bottom to top, the gas-liquid contact is more sufficient, and the humidity of the gas can be provided, thereby improving the humidification efficiency.

[0056] In one embodiment of the present application, see Figure 2, the wet film evaporator 100 may include a water tank 120, a water pipe 130 and a plurality of irrigation pipes 140. The water tank 120 is used to set a liquid, and the liquid is, for example, water or other medium that is more sensitive to temperature (for example, smaller specific heat capacity). Exemplarily, the liquid in the water tank 120 may be 25% salt water. When the temperature-sensitive liquid medium is affected by the external temperature change, it can feedback the temperature change to the temperature sensor more quickly, and then realize the rapid control of the temperature through the liquid heat exchanger 210, etc. Similarly, the temperature-sensitive liquid medium can feel more subtle temperature changes and has a higher "temperature range", thereby improving the temperature control accuracy. By replacing the liquid medium, the effect of controlling the temperature and humidity more quickly and accurately can be achieved. The water pipe 130 is used to transport the liquid, and the plurality of irrigation pipes 140 are respectively connected to the water pipe 130, and the plurality of irrigation pipes 140 are arranged above the membrane surface, so that the irrigation area that can be covered is larger, so that the liquid at each position of the membrane surface is sprayed evenly, the gas-liquid contact is more sufficient, and the humidification efficiency is higher.

[0057] In one embodiment of the present application, see Figure 2 The wet film evaporator 100 includes a collecting device 150 disposed below the membrane surface, and the collecting device 150 is connected to the water tank 120 to collect liquid passing through the membrane surface and send the liquid into the water tank 120 to achieve liquid recycling with high stability. For example, the collecting device 150 may be funnel-shaped.

[0058] In one embodiment of the present application, see Figure 2 The liquid heat exchanger 210 is disposed in the water tank 120 to facilitate direct heat exchange with the liquid medium.

[0059] In one embodiment of the present application, see Figure 1 The gas heat exchanger 310 is disposed between the air inlet 410 and the wet film evaporator 100 to facilitate adjusting the temperature of the gas passing through the wet film evaporator 100 to achieve various working states.

[0060] In one example, the gas heat exchanger 310 may be a gas heater. In another example, the liquid heat exchanger 210 may be a liquid heater.

[0061] In one embodiment of the present application, see Figure 1 The fog-free humidification module may further include a frame 600 for loading the components described above and other possible components.

[0062] The above is a preferred embodiment of the present application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
