DETAILED DESCRIPTION

[0025] like Figures 1 to 3 As shown, the utility model provides an air purification and heating device, comprising: a shell 1, on which an air inlet 101 and an air outlet 102 are provided, a filtering mechanism 2, a disinfecting mechanism 3, an air suction fan 4 and a static pressure box 5 are sequentially installed in the shell 1 along the air inlet direction, the static pressure box 5 is connected to the air outlet 102, a PTC heater 501 is installed in the static pressure box 5 near the air outlet 102, and the air outlet of the air suction fan 4 is connected to the static pressure box 5;

[0026] The filter mechanism 2 includes a filter screen 201, a filter sponge 202, and a purification filter screen 203 which are sequentially installed in the housing 1 along the air inlet direction. There are two filter sponges 202 to improve the filtering effect and save costs. The purification filter screen 203 is composed of ultra-fine glass fiber and artificial fiber filter paper, which can filter air particles larger than 0.3um, and the filtering efficiency can reach 99%;

[0027] The disinfection mechanism 3 includes a mesh shell 301, which is meshed to facilitate air passage. A liquid storage tank 302 is provided at the bottom of the mesh shell 301. The liquid storage tank 302 stores a disinfectant capable of removing toxic gases such as ammonia and hydrogen sulfide. The disinfectant has a preset color change through a chain reaction, so that it is easy to judge and remind to replace the disinfectant by color. A wet curtain 303 is installed in the mesh shell 301, and the liquid storage tank 302 is connected to a pipe 304. The water inlet of the pipe 304 extends into the liquid storage tank 302, and the water outlet of the pipe 304 extends to the top of the wet curtain 303. A water pump (not shown in the figure) is installed in the mesh shell 301 to pump the disinfectant in the liquid storage tank 302 to the top of the wet curtain 303 through the pipe 304. The disinfectant is discharged from the pipe 304, poured on the wet curtain 303 and falls into the liquid storage tank 302 for recycling. Among them, the wet curtain 303 has a honeycomb structure, which is a finished product well known to those skilled in the art and will not be described here.

[0028] In this solution, the suction fan 4 is started to suck in external air from the air inlet 101. The air is filtered out of air particles through the filter 201, the filter sponge 202, and the purification filter 203 in turn. The air then passes through the wet curtain 303, is disinfected and deodorized by the disinfectant, and is discharged into the static pressure box 5 through the air outlet of the suction fan 4. After being heated by the PTC heater 501, the air is discharged through the air outlet 102. The static pressure box 5 is used to stabilize the airflow, reduce turbulence to achieve the purpose of reducing noise, and can increase the static pressure to ensure the effective operation of the device, and can evenly distribute the air volume to ensure uniform heating of the air by the PTC heater 501.

[0029] This solution can disinfect, sterilize and deodorize the air by setting the wet curtain 303, thereby improving the air quality.

[0030] In one embodiment of the utility model, the static pressure box 5 is provided with a notch that matches the air outlet of the suction fan 4, the air outlet of the suction fan 4 extends from the notch to the inside of the static pressure box 5, and the air outlet of the suction fan 4 is sealed and connected to the static pressure box 5.

[0031] In this solution, the air outlet of the suction fan 4 is extended to the inside of the static pressure box 5 and sealed, thereby ensuring the speed at which air enters the static pressure box 5 and avoiding air leakage.

[0032] In one embodiment of the utility model, a partition 103 is provided in the shell 1, and the partition 103 divides the internal chamber of the shell 1 into an air inlet channel 104 and a heating chamber 105. The air inlet channel 104 and the heating chamber 105 are connected to form a U shape, and the suction fan 4 and the static pressure box 5 are installed in the heating chamber 105 to reduce the length of the shell 1; the suction port of the suction fan 4 is arranged opposite to the partition 103 to avoid deformation of the wet curtain 303 caused by excessive suction wind force.

[0033] In one embodiment of the present invention, the air inlet 101 and the air outlet 102 are respectively arranged on two opposite side walls of the housing 1 to avoid interference between the external air and the air purified by the air purification and heating device.

[0034] In one embodiment of the present invention, the wet curtain 303 is U-shaped, so that air passes through a double layer of the wet curtain 303, thereby improving the air purification effect.

[0035] In one embodiment of the utility model, a temperature sensor is installed in the shell 1, and the temperature sensor is used to transmit a temperature sensing signal to a controller 6 installed on the shell. The controller 6 controls the opening or closing of the PTC heater 501 according to the temperature sensing signal to achieve an automatic heating effect and reduce energy consumption.

[0036] In one embodiment of the utility model, an air quality sensor for detecting air quality is installed in the shell 1. The air quality sensor transmits the sensing signal to the controller 6. The controller 6 controls the opening or closing of the water pump according to the sensing signal. When the air quality does not meet the standard, the controller 6 turns on the water pump, and the water pump pumps the disinfectant to the wet curtain 303, so that the air passing through the wet curtain 303 is disinfected, sterilized and deodorized; when the air quality meets the preset conditions, the controller 6 turns off the water pump, realizing automatic air purification and filtration, and reducing energy consumption.

[0037] In one embodiment of the utility model, the filter mechanism 2 is slidably installed in the shell 1, wherein the filter 201, the filter sponge 202, and the purification filter 203 are all slidably installed in the shell 1 to facilitate disassembly and replacement; specifically, a cover body 106 is detachably installed on the shell 1, and opening the cover 106 can display the internal chamber of the shell 1, and the shell 1 is provided with limiting slide grooves that respectively cooperate with the filter 201, the filter sponge 202, and the purification filter 203. After opening the cover body 106, the filter 201, the filter sponge 202, and the purification filter 203 are respectively slid out or installed along the limiting slide grooves to realize the replacement of the filter mechanism 2.

[0038] In one embodiment of the utility model, the air purification and heating device also includes a bracket 7 for placing the shell 1, and a universal wheel 701 is installed at the bottom of the bracket 7. A handle 702 is provided on the bracket 7 to facilitate the movement of the air purification and heating device by holding the handle 702.

[0039] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
