Description

Technical Field

[0001] The utility model relates to the field of machinery, in particular to a constant temperature and humidity purification integrated machine. Background Art

[0002] Archival materials are very sensitive to temperature and humidity. Paper, ink, glue and other materials will undergo different physical and chemical changes under different temperatures and humidity. Too high or too low temperature will cause the paper to deform, age, and fade, affecting the shelf life of the archives; and humidity fluctuations may cause the paper to become damp and moldy, and in severe cases may even cause the archives to be completely destroyed. Therefore, in order to maintain the stability of archival materials, the temperature and humidity in the archive room must be controlled to keep it in a relatively stable state (usually the temperature is 14-24°C, and the relative humidity is 45-60%). Therefore, constant temperature and humidity equipment is usually installed in the archive room to keep the temperature and humidity in the archive room within a relatively constant range. In addition, in order to avoid the influence of dust in the air on the archives, a filter structure is usually set up to filter the air. The filter structure is usually divided into two levels, namely the primary filter and the multi-layer filter element. The current problems are:

[0003] 1. Since the primary filter needs to filter out large air particles, it often needs to be taken out, cleaned and replaced, which is time-consuming.

[0004] 2. The multi-layer filter element has small pores and large resistance, which leads to a high air pressure at the air inlet. Therefore, the air tightness of the installation point must be ensured during installation, and the wind cover must fit tightly with the outer frame of the multi-layer filter element. However, the existing installation structure does not have a pressure indication function, which leads to problems such as loose pressing and air leakage when installing after replacing the multi-layer filter element, or excessive pressing force causing damage to the frame.

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and examples.

[0021] Example 1

[0022] like Figures 1 to 3 A constant temperature and humidity purification machine shown in the figure includes a cabinet 1, an air inlet 2, an air outlet louver 3, a first air inlet hood 4, a second air inlet hood 5, a filter element structure 6, an outer frame 61, a three-in-one HEPA filter 62, a lower frame 7, an upper frame 8, bolts 9, an upper pressure plate 10, a positioning protrusion 91, an upper pressure plate 10, a spring 11, a lower pressure plate 12, a first air outlet hood 13, a bellows 14, an air outlet pipe 15, a second air outlet hood 16, a cyclone separator 17, a dust collection box 18, a humidifier 19, an internal threaded pipe 20, a first three-way valve 21, a refrigeration serpentine pipe 22, a heating serpentine pipe 23, an electric cooling plate 24, a second three-way valve 25, a water-blocking pipe 26, a UV lamp 27 and an air pump 28.

[0023] The air inlet 2 is at the bottom of the cabinet 1, the air outlet louver 3 is at the upper part of the cabinet 1, the first air inlet cover 4 is installed at the air inlet 2, and the second air outlet cover 16 is installed at the air outlet louver 3. A temperature sensor and a humidity sensor (which belong to the prior art and are not shown) are arranged at the air inlet 2.

[0024] When in use, the air pump 28 draws in external air through the air inlet 2 and the first air inlet hood 4, and then enters the cyclone separator 17 to separate the larger dust particles into the dust collection box 18. In this way, the dust collection box 18 can be taken out after a period of time and the dust can be poured out. The air is then further filtered through the three-in-one HEPA filter 62 (ionic silver antibacterial cloth + multi-layer HEPA filter element + coconut shell activated carbon filter element). After the filtered air is humidified by the humidifier 19, the first three-way valve 21 and the second three-way valve 25 are opened according to the set temperature, so that the air flows through the heating surface of the electric cooling plate 24 for heating or the process cooling surface for cooling, and then flows out. The air outlet louver 3 can adjust the air outlet angle.

[0025] When the filter element structure 6 needs to be replaced, the bolt 9 is loosened and the filter element structure 6 is pulled out, and the filter element structure 6 is inserted again and the bolt 9 is tightened. The bolt 9 drives the upper pressure plate 10 downward and applies pressure to the lower pressure plate 12 through the spring 11 until the positioning protrusion 91 presses against the lower pressure plate 12 and then rotates into place. At this time, it indicates that the filter element structure 6 has been pressed and fixed, thereby preventing the problem of insufficient sealing due to too low pressure or damage to the filter element structure 6 due to excessive pressure.

[0026] A water-blocking pipe 26 is installed in the water tank of the humidifier 19, and an ultraviolet lamp 27 is installed in the water-blocking pipe 26 to sterilize the added water. Several water level sensors (not shown) are also installed in the water tank of the humidifier 19 to indicate the water level therein. Universal wheels are installed at the bottom of the cabinet 1 for easy movement, and a liquid crystal touch screen is installed in the middle to display and set the temperature and humidity.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
