Description

Technical Field

[0001] This utility model relates to the field of disinfection and purification, and specifically refers to a DC disinfection and purification integrated machine. Background Technology

[0002] The integrated disinfection and purification machine mainly relies on an AC fan as the air power source. Air passes through the pre-filter and activated carbon filter and enters the air disinfection chamber. Inside the chamber, the air is irradiated by a 254nm ultraviolet lamp to remove microorganisms. Then, the air is discharged outside the machine by the fan. The overall power consumption of the product is mainly due to the AC fan, which has disadvantages such as low power and high wattage.

[0003] Existing technology 202020275427.3 discloses an integrated air disinfection and purification machine for enclosed elevator spaces. Although it is also driven by DC, its disinfection and other functions are set up externally. This not only occupies space but also prevents people from entering during sterilization, which affects their lives. Furthermore, it is impossible to know immediately whether the indoor air quality meets the requirements, thus failing to stop purification in time and increasing energy consumption. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a DC disinfection and purification integrated machine.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a DC disinfection and purification integrated machine, comprising a rectangular purification and disinfection box, two sealing baffles on both sides of the purification and disinfection box for sealing, a filter disinfection chamber located in the lower middle part of one side of the length direction inside the purification and disinfection box, an exhaust chamber located on the other side of the purification and disinfection box, a detection chamber located directly above the filter disinfection chamber inside the purification and disinfection box, several ventilation holes provided on one of the two sealing baffles at the positions of the filter disinfection chamber and the detection chamber, a filter disinfection component located in the filter disinfection chamber, a DC fan connected to the filter disinfection chamber at the air intake of the exhaust chamber, several exhaust ports connected to the exhaust chamber on one side of the width direction of the purification and disinfection box, and an air quality sensor located in the detection chamber for detecting air quality.

[0006] Preferably, the filtration and disinfection assembly includes a PET primary filter disposed on the side of the filtration and disinfection chamber near the sealing baffle, an ultraviolet lamp for disinfection disposed in the filtration and disinfection chamber near the DC fan intake, and a composite filter disposed in the filtration and disinfection chamber between the PET primary filter and the ultraviolet lamp.

[0007] Preferably, the controller is located at the bottom of the exhaust chamber inside the purification and disinfection box.

[0008] Preferably, the two sealing baffles are located on one side of the exhaust cavity, with a display screen on one of the sealing baffles.

[0009] Preferably, the four drive wheels are located at the four corners of the bottom of the purification and disinfection box.

[0010] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0011] This invention, by incorporating a DC fan, can provide a larger air volume and better airflow control at the same power, thus being more energy-efficient and effective. The operating noise is typically lower than that of an AC motor, providing a quieter user experience. The disinfection setting is located inside the purification and disinfection box, reducing space occupancy. An air quality sensor can detect indoor air quality in real time, allowing for simultaneous purification and disinfection while also stopping the machine to save energy. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] Appendix Figure 1-3The DC disinfection and purification integrated machine of this utility model includes a rectangular disinfection box 1, two sealing baffles 2 on both sides of the disinfection box 1 for sealing, a filter disinfection chamber 3 located in the lower middle part of one side along the length of the disinfection box 1, an exhaust chamber 4 located on the other side of the disinfection box 1, a detection chamber 5 located directly above the filter disinfection chamber 3 in the disinfection box 1, several ventilation holes 6 on one of the two sealing baffles located at the positions of the filter disinfection chamber 3 and the detection chamber 5, and a filter disinfection assembly 7 located in the filter disinfection chamber 3. The filter and disinfection assembly 7 includes a DC fan 8 connected to the air intake of the exhaust chamber 4 and the filter and disinfection chamber 3; several exhaust ports 9 connected to the exhaust chamber 4 on one side of the purification and disinfection box 1 in the width direction; and an air quality sensor 10 installed in the detection chamber 5 for detecting air quality. The filter and disinfection assembly 7 includes a PET primary filter 71 installed on the side of the filter and disinfection chamber 3 near the sealing baffle 2; an ultraviolet lamp 72 for disinfection installed in the filter and disinfection chamber 3 near the air intake of the DC fan 8; and a composite filter 73 installed in the filter and disinfection chamber 3 and located between the PET primary filter 71 and the ultraviolet lamp 72.

[0019] Furthermore, the controller 11 located at the bottom of the exhaust chamber 4 inside the purification and disinfection box 1 facilitates automatic control of turning the purification and disinfection mode on or off.

[0020] Furthermore, the two sealing baffles 2 are located on one side of the exhaust cavity 4, and the display screen 12 on one of the sealing baffles 2 facilitates the viewing of air quality and operation of the equipment.

[0021] Furthermore, the four drive wheels 13 located at the four corners of the bottom of the purification and disinfection box 1 facilitate movement.

[0022] In use: When the air quality sensor 10 fails to meet the requirements, it sends an electrical signal to the controller 11. The controller 11 then starts the DC fan 8 to draw in air. Indoor air enters the filtration and disinfection chamber 3 through the vent holes 6 on the sealing baffle 2. The air first passes through the PET pre-filter 71, which blocks larger particles in the air. The pre-filtered air then enters the composite filter 73, where the high-efficiency HEPA filter adsorbs micron-sized dust particles. The activated carbon particles in the combined filter 73 adsorb harmful gaseous pollutants (such as formaldehyde, xylene, toluene, etc.) and capture and lock them inside the activated carbon pores. The air after deep filtration then passes through the ultraviolet lamp 72, which radiates and sterilizes the air. The sterilized air then enters the exhaust chamber 4 through the DC fan 8 and then returns to the room through the exhaust port 9. After filtration for a period of time, when the air quality sensor 10 shows that the air quality meets the requirements, it sends an electrical signal to the controller 11, which then stops the DC fan 8, and the purification and disinfection process ends.

[0023] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
