Description

Technical Field

[0001] The utility model relates to the technical field of constant temperature and humidity equipment, in particular to a humidification module for box-type products. Background Art

[0002] Constant temperature and humidity chambers are mostly used for testing, monitoring and storing products in specific environments, and are widely used in the market; for constant humidity, a set of humidification modules will be equipped in the chamber. The traditional humidification module is the evaporation humidification equipment of a boiler. This equipment can achieve efficient humidification effect. However, due to the simple structure of the traditional boiler humidifier, there are problems such as dry burning damage, excessive cold water supply, and waste of the discharged heated water in the furnace, resulting in an increase in operating costs. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a humidification module for box-type products with functions of preventing dry burning, saving water and accurately monitoring water level.

[0004] To achieve the above object, the utility model provides a humidification module for box-type products, which includes a boiler, a water inlet module, a drainage module, a water-saving module, a PTC heater, a liquid level sensor and a moisture exhaust pipe;

[0005] The water inlet module is communicated with the water inlet of the boiler and is signal-connected with the liquid level sensor. The liquid level sensor is arranged in the boiler to detect the water level; the drainage module is connected with the drainage port at the bottom of the boiler; one end of the water-saving module is communicated with the boiler, and the other end is communicated with the drainage port; the PTC heater is communicated with the inside of the boiler to heat the boiler; the moisture exhaust pipe is communicated with the moisture exhaust port of the boiler, and an intake valve is arranged on the moisture exhaust pipe.

[0006] Further, the water inlet module includes a water storage tank and a water inlet pump;

[0007] The water storage tank is communicated with the water inlet of the boiler through the water inlet pump, and a water inlet valve is arranged between the water inlet pump and the boiler; the water inlet pump is signal-connected with the liquid level sensor through a PLC control module.

[0008] Further, the drainage module includes a first drainage pipe and a drainage valve. The drainage valve is arranged on the first drainage pipe, and the first drainage pipe is communicated with the drainage port of the boiler.

[0009] Further, the water-saving module includes a water accumulation kettle, a pressure balance pipe and a second drainage pipe;

One end of the second drainage pipe is communicated with the water accumulation kettle, and the other end is communicated with the first drainage pipe for drainage.

[0011] Compared with the prior art, the advantages of the utility model are as follows:

[0012] 1. The utility model replaces the traditional heating tube with a PTC heater, and utilizes the change of the internal resistance and heating power unique to PTC heating. As the temperature of the internal water body increases during heating and evaporation, an effective dry-burning prevention function is achieved.

[0013] 2. By setting up a water-saving module in the utility model, due to the pressure change generated in the furnace after heating and cooling, the water accumulation kettle can play the role of storing water and refluxing, avoiding the direct discharge of internal water and causing serious waste of resources.

[0014] 3. The utility model realizes the switching between high and low humidity by setting a liquid level sensor in cooperation with an air inlet valve, and can achieve precise water supply by setting a liquid level sensor in cooperation with a water inlet valve, avoiding large fluctuations in humidity. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] To make the purpose, technical solutions and advantages of the utility model clearer, the technical solutions of the utility model will be further described below.

[0017] As Figure 1 shown, the utility model provides a humidification module for a box-type product, which includes a boiler 9, a water inlet module, a drainage module, a water-saving module, a PTC heater 1, a liquid level sensor 2 and a dehumidification pipeline;

[0018] The water inlet module is connected to the water inlet of the boiler 9 and is in signal connection with the liquid level sensor 2. The liquid level sensor 2 is arranged in the boiler 9 to detect the water level; the drainage module is connected to the drainage port at the bottom of the boiler 9; one end of the water-saving module is connected to the boiler 9, and the other end is connected to the drainage port; the PTC heater 1 is connected to the inside of the boiler 9 to heat the boiler 9; the dehumidification pipeline is connected to the dehumidification port 3 of the boiler 9, and an air inlet valve 7 is arranged on the dehumidification pipeline. By adding the air inlet valve 7 and controlling the start and stop of the valve, it can quickly and stably reach the set value when switching between high and low humidity.

[0019] In this embodiment, the water inlet module includes a water storage tank 11 and a water inlet pump 8; the water storage tank 11 is connected to the water inlet of the boiler 9 through the water inlet pump 8, and a water inlet valve 5 is arranged between the water inlet pump 8 and the boiler 9; the water inlet pump 8 is in signal connection with the liquid level sensor 2 through a PLC control module. During the heating process of the boiler 9, the internal water will continuously evaporate and decrease. After the liquid level sensor 2 senses that the water level reaches the lowest threshold, the water inlet valve 5 is opened through the PLC control module, and the water inlet pump 8 is started to supply water; when the liquid level sensor 2 senses that the water level reaches the highest threshold, the water inlet valve 5 is opened through the PLC control module, and the water inlet pump 8 is closed to avoid excessive cold water supply and cause large fluctuations in humidity.

[0020] In this embodiment, the drainage module includes a first drainage pipe and a drainage valve 6. The drainage valve 6 is arranged on the first drainage pipe. The first drainage pipe is communicated with the drainage port of the boiler 9. When the cumulative humidification duration reaches a certain value and there is no current humidity control requirement, the drainage valve 6 is opened to drain water automatically, so as to achieve the purpose of cleaning the interior of the boiler 9.

[0021] In this embodiment, the water-saving module includes a water accumulation pot 10, a pneumatic balance pipe 4 and a second drainage pipe; one end of the pneumatic balance pipe 4 is connected to the drainage port at the bottom of the boiler 9, and the other end is communicated with the bottom of the water accumulation pot 10. One end of the second drainage pipe is communicated with the water accumulation pot 10, and the other end is communicated with the first drainage pipe for drainage; the water accumulation pot 10 is added and the installation height is set. It is connected with the boiler 9 through the pneumatic balance pipe 4. When the intake valve 7 is in the closed state, the pressure generated by the heating of the boiler 9 is released through the balance pipe, and the excess water is discharged through the overflow port of the water accumulation pot 10. After the water accumulation pot 10 cools down, the water below the overflow port flows back into the boiler 9 to achieve the purpose of water saving.
