Description

Technical Field

[0001] This utility model relates to the field of air purification equipment, and in particular to a modular indoor air purifier. Background Technology

[0002] As people's living standards improve, indoor air quality is receiving increasing attention. Indoor air pollution mainly originates from VOCs in building materials, as well as pollutants such as bacteria, viruses, and dust in the air. To improve indoor air quality, indoor air purifiers have emerged.

[0003] Traditional indoor air purifiers have limited functionality, typically addressing only one type of pollution problem, such as formaldehyde removal, dust removal, or sterilization. However, to meet the demands of comprehensive air treatment in complex environments, current technologies combine different functional modules to create multi-functional indoor air purifiers capable of simultaneously purifying air from multiple dimensions.

[0004] For example, Chinese patent CN119146519A discloses a smart multi-strain composite air sterilizer, including a housing with several purification layers fixedly connected inside for air sterilization. An air extractor is fixedly connected to the bottom wall of the housing for air extraction. A heat dissipation vent is provided on one side of the housing for expelling hot air from inside. Dust removal components are installed on both sides of the inner wall of the housing, including dust outlet grooves on both sides. The purification layers are an electrostatic adsorption filter layer, an ultraviolet lamp layer, and an ozone generator layer, capable of sterilizing and removing dust from the air. However, the above air sterilizer may have the following shortcomings: 1. The purification layers are fixedly connected to the interior of the housing, making maintenance inconvenient, and the purification layers cannot be arbitrarily combined according to actual conditions, resulting in poor flexibility. 2. Although dust removal components are installed on both sides of the inner wall of the housing, the air first passes through the air extractor and then the dust removal components, making the air extractor prone to dust accumulation, which gradually affects its performance and lifespan.

[0005] In view of this, the present invention proposes a modular indoor air purifier to solve the above problems. Summary of the Invention

[0006] This invention overcomes the shortcomings of the above-mentioned technologies and provides a modular indoor air purifier. Each module can be freely combined and disassembled, and can be flexibly applied to air purification in various indoor places.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

The intermediate purification module group includes at least one of a VOC catalytic decomposition module, a negative ion module, a sterilization module, and an oxygenation module. All modules have a box-like shell, and any two boxes are detachably connected by a mechanical connection structure. The bottom of the box has an air inlet, and the top of the box has an air outlet. A ventilation component is provided at the air inlet. The box of the air intake filter module has a first mounting plate, on which a first fan is mounted. A dust collection tray is placed on the ventilation component of the air intake filter module, and a dust removal filter plate is provided between the first fan and the dust collection tray.

[0009] Preferably, the ventilation component includes a solid plate with an upwardly inclined air intake grille on its outer periphery. The top of the air intake grille is connected to the air outlet, and the size of the air outlet is adapted to the size of the ventilation component. When the two boxes are connected by a mechanical connection structure, the ventilation component of the upper box can pass through the air outlet of the lower box and enter the lower box.

[0010] Preferably, the first mounting plate is provided with a fan inlet, the first fan is installed at the fan inlet, the dust removal filter plate is formed into a conical filter cover, one end of the conical filter cover is an opening opposite to the fan inlet, the other end of the conical filter cover faces the dust collection tray, and the dust collection tray is placed on a solid plate.

[0011] Preferably, the housing of the VOC catalytic decomposition module is provided with a first breathable partition, the first breathable partition is equipped with a VOC decomposition catalyst, and the solid plate of the VOC catalytic decomposition module is provided with a VOC detection sensor.

[0012] Preferably, the sterilization module has an ultraviolet lamp and a photocatalyst for photocatalyzing ozone installed inside its housing, and an ozone detection sensor is installed on the solid plate of the sterilization module.

[0025] The following examples provide a more detailed description of the features and other related characteristics of this utility model, to facilitate understanding by those skilled in the art:

[0026] Reference Figures 1-3 An embodiment of the present invention, a modular indoor air purifier, is presented:

[0027] A modular indoor air purifier comprises, from bottom to top, an intake filtration module 1, an intermediate purification module group, and an exhaust module 5. The intermediate purification module group includes at least one of a VOC catalytic decomposition module 2, a negative ion module 4, a sterilization module 3, and an oxygenation module.

[0028] All modules are housed in a box 6, and any two boxes 6 can be detachably connected via a mechanical connection structure. The bottom of the box 6 has an air inlet, and the top of the box 6 has an air outlet 66. A ventilation component 7 is located at the air inlet. Inside the box 61 of the air intake filter module 1, there is a first mounting plate 11. A first fan 13 is mounted on the first mounting plate 11. A dust collection tray 12 is placed on the ventilation component 7 of the air intake filter module 1. A dust removal filter plate 14 is located between the first fan 13 and the dust collection tray 12. The dust removal filter plate 14 prevents dust particles from accumulating on the first fan 13 and the module group above it. The dust collection tray 12 collects airborne dust particles, facilitating regular cleaning by the user.

[0029] The ventilation component 7 includes a solid plate 71 with an upwardly inclined air intake grille 72 on its outer periphery. The air intake grille 72 ensures that air flows evenly into each module. The top of the air intake grille 72 is connected to the air outlet 66, the size of which is adapted to the size of the ventilation component 7. When the two boxes 6 are connected by a mechanical connection structure, the ventilation component 7 of the upper box 6 can pass through the air outlet 66 of the lower box 6 and enter the lower box 6, increasing the stability of the connection between the boxes 6.

[0030] The first mounting plate 11 is provided with a fan inlet, and the first fan 13 is installed at the fan inlet. The dust removal filter plate 14 forms a conical filter cover. One end of the conical filter cover is an opening opposite to the fan inlet, and the other end of the conical filter cover faces the dust collection tray 12. The conical filter cover can guide dust particles to fall onto the dust collection tray 12, thereby improving dust removal efficiency.

[0031] Specifically, in order to dehumidify the air, a dehumidifying plate can be installed on the inside of the dust filter plate 14.

[0032] like Figure 2 As shown, the housing 62 of the VOC catalytic decomposition module 2 is equipped with a first breathable baffle 21, on which a catalyst holder 22 is mounted. The catalyst holder 22 houses the VOC decomposition catalyst and a catalyst detection sensor for monitoring the health status of the VOC decomposition catalyst. Specifically, the VOC decomposition catalyst is a CeO2-TiO2 catalyst, capable of efficiently decomposing harmful substances from VOCs into harmless water and carbon dioxide. A VOC detection sensor is mounted on the solid plate 71 of the VOC catalytic decomposition module 2.

[0033] The sterilization module 3 has an ultraviolet lamp 31 and a photocatalyst 32 for photocatalyzing ozone installed inside its housing 63. The ultraviolet lamp 31 can destroy the DNA / RNA of microorganisms, and the photocatalyst 32 generates free radicals under the action of the ultraviolet lamp 31, which decompose harmful gases (such as ozone) and sterilize. An ozone detection sensor is installed on the solid plate 71 of the sterilization module 3 to monitor the ozone content in the air.

[0034] The negative ion module 4 has a second breathable partition 42 inside its housing 64, and a negative oxygen ion generator 41 mounted on the second breathable partition 42. The negative oxygen ion generator 41 can ionize oxygen molecules in the air, thereby generating negatively charged oxygen ions, effectively neutralizing positive ions and pollutants in the air, freshening the air, and promoting human health. A negative oxygen ion content detection sensor is installed on the solid plate 71 of the negative ion module 4.

[0035] The oxygenation module housing contains an oxygen-generating device (not shown in the attached diagram), such as an oxygen generator using sodium peroxide. An oxygen content detection module is mounted on the solid plate 71 of the oxygenation module.

[0036] like Figure 3 As shown, the mechanical connection structure is provided by the insertion rod 68 at the bottom of the box 6 and the slot 67 at the top of the box 6. The insertion rod 68 is inserted into the slot 67, so that the two boxes 6 are connected. The operation is simple and convenient for the maintenance and modular combination of the air purifier.

[0037] The air outlet module 5 contains a second mounting plate 51 and a second fan 52 mounted on the second mounting plate 51. The first fan 13 and the second fan 52 serve as the power source for the air purifier, allowing indoor air to enter through the air inlet at the bottom of the air purifier, pass through all purification modules, and finally exit through the air outlet 66 at the top of the air purifier, optimizing the airflow path and improving air purification efficiency. The air outlet 66 of the air outlet module 5 is equipped with a ventilated protective cover 53, which not only ensures even airflow from the air purifier but also prevents other objects from falling into the air outlet module 5 and damaging the second fan.

[0038] A pollutant detection sensor is mounted on the solid plate of the air outlet module 5 to detect the quality of the purified air. A VOC detection sensor, an ozone detection sensor, and a negative ion concentration detection sensor are used to detect the quality of the air before purification.

[0039] In this embodiment, the bottom end of the plug 68 is an electrical connection contact point. The plug 68 is hollow, allowing wires to pass through, and the electrical appliances of each module can be electrically connected to the adjacent electrical connection contact point.

[0040] The pole 68 located at the bottom of the air purifier can be equipped with casters for easy movement of the air purifier.

[0041] This invention allows for the creation of multiple air purification modes through freely combinable modules. For example, during or after renovation, the air intake filter module 1, VOC catalytic decomposition module 2, and air outlet module 5 can be combined. In normal use, the air intake filter module 1, VOC catalytic decomposition module 2, negative ion module 4, oxygenation module, and air outlet module 5 can be combined. For locations requiring disinfection and sterilization, the air intake filter module 1, VOC catalytic decomposition module 2, negative ion module 4, sterilization module 3, oxygenation module, and air outlet module 5 can be combined.

[0042] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
