Description

Technical Field

[0001] The present application relates to the technical field of air purification equipment, and more specifically, to a negative oxygen ion formaldehyde removal warm air humidification air purifier. Background Art

[0002] An air purifier is a household appliance used to remove pollutants from indoor air and improve air quality. As modern consumers become increasingly aware of environmental protection, formaldehyde levels in newly renovated homes have drawn their attention. Formaldehyde primarily originates from decorative materials, artificial boards, furniture, paints, coatings, curtains, textiles, and wallpaper, and can be released for over 10 years. Therefore, air purifiers that can remove formaldehyde are widely popular. Existing air purifiers primarily reduce indoor formaldehyde levels through the reaction of negative oxygen ions with formaldehyde. Typical solutions include:

[0003] 1. Chinese utility model patent publication number CN204478302U discloses an air purification device comprising a housing, a formaldehyde removal layer, and a negative ion release layer. An air inlet is provided on one side of the housing, and an air outlet is provided on the other side. The formaldehyde removal layer and the negative ion release layer are arranged side by side within the housing, separating the air inlet and outlet. The device is characterized in that the formaldehyde removal layer comprises an air filter substrate and a formaldehyde-removing coating attached to the air filter substrate that directly reacts chemically with formaldehyde. The negative ion release layer comprises an air filter substrate and a modified tourmaline layer attached to the air filter substrate. Directly filtering air with the formaldehyde removal layer and the negative ion release layer will quickly become covered by dust particles, thereby losing their ability to generate negative oxygen ions and interact with formaldehyde in the air.

[0004] 2. The Chinese invention patent with publication number CN106871285A discloses a negative oxygen ion formaldehyde removal warm air humidification air purifier, which is equipped with a palygorskite composite filter. The housing is fixedly connected to the air inlet grille, the bottom of the housing is fixedly connected to the water tray, the right side of the housing is fixedly connected to the filter, the left side of the housing is fixedly connected to the heating plate, the dripper at the upper end of the filter is fixedly connected to the right side wall of the housing, the upper end section of the housing is fixedly connected to the fan, and the upper left corner of the front wall of the housing is fixedly connected to the control panel. The upper end of the filter is fixedly connected to the upper frame, the lower end of the filter is fixedly connected to the lower frame, and the filter inside the filter is fixedly connected to two layers of continuously bent glass fiber membrane filter screens. A composite sterilizing filter is placed between the two layers of filter screens. The heating plate switch on the control panel is electrically connected to the heating plate, and the fan switch is electrically connected to the fan. The upper end of the dripper has a water inlet, and the upper end of the fan has an air outlet. The invention proposes to continuously drip water onto the palygorskite composite filter screen used to remove formaldehyde and filter air through the dripper, thereby cleaning it. However, the palygorskite composite filter screen that is wet for a long time is very prone to breeding bacteria.

[0005] It can be seen that existing air purifiers have the problem that the negative oxygen ion generators that filter the air and eliminate formaldehyde are easily contaminated and covered with dust, and continuous cleaning can easily breed bacteria. Utility Model Content

[0006] To solve the problems existing in existing air purifiers, the technical solution adopted in this application is a negative oxygen ion formaldehyde removal, warm air humidification air purifier, comprising a housing and a control system. The housing is provided with a detachable water tank, an air outlet, and an air inlet. An air purification passage is connected between the air outlet and the air inlet, and at least one wind power supply device is provided in the air purification passage.

[0007] It also includes an annular negative oxygen ion generator circulation passage that intersects the air purification passage twice. The air purification passage includes a filtration section, a first intersection section, a formaldehyde adsorption section, a second intersection section and a humidification section in sequence. The negative oxygen ion generator circulation passage includes a first intersection section, a second drying section, a second intersection section and a first drying section in sequence. A carrier is provided in the negative oxygen ion generator circulation passage. The carrier is loaded with particulate negative oxygen ion generator, and a segmented filter is provided to divide the carrier into multiple segments. A blocking filter is provided on the side wall of the carrier. The negative oxygen ion generator circulation passage is provided with a rotating device to rotate the carrier. The humidification section is provided with a liquid outlet device for spraying liquid toward the second intersection section.

[0008] Optionally, the control system includes a detection module, a signal transmission module, a display module, a control module, an alarm module and a power supply.

[0009] Optionally, the formaldehyde adsorption section includes a detachable activated carbon layer.

[0010] Optionally, the wind supply device is arranged between the filtering section and the first crossing section.

[0011] Optionally, the filtration section includes a primary filter and a HEPA filter.

[0012] Optionally, outer walls of the first drying section and the second drying section are surrounded by heating pipes.

[0013] Optionally, the detection module includes an air outlet temperature sensor arranged at the air outlet, a liquid level sensor arranged at the water tank, and drying temperature sensors arranged at the first drying section and the second drying section.

[0014] Optionally, a detachable filter box is provided at the air inlet position, and the detachable filter box includes a filter box frame, a mesh cover and a bottom mesh. A detachment sensor is provided at the installation position of the detachable filter box.

[0015] Optionally, the particle size of the negative oxygen ion generator is distributed between 0.3-1 mm.

[0016] Optionally, the mesh diameters of the segment filter and the barrier filter are both smaller than 0.27 mm.

[0017] The beneficial effects of the utility model are:

[0018] 1. The air to be purified is drawn into the negative oxygen ion formaldehyde removal, warm air, and humidification air purifier provided herein under the influence of a wind power supply device. The air enters the air purification path through the air inlet, passes through the filtration section to filter out larger solid pollutants, and then enters the first crossover section, where formaldehyde is removed by a negative oxygen ion generator. The air then enters the formaldehyde adsorption section, where residual formaldehyde is adsorbed. The air to be purified becomes clean air, which is then carried away by the second crossover section, where water vapor carrying negative oxygen ions is removed. The moisture from the composite humidification section and the hot air from the drying section are then delivered through the air outlet, producing warm air with formaldehyde removal and humidification.

[0019] 2. The negative oxygen ion generator exists in the form of particles. The increased specific surface area can produce more negative oxygen ions. The air has completed preliminary filtration through the filter section before passing through the negative oxygen ion generator to prevent the negative oxygen ion generator from being covered by dust and dirt. The negative oxygen ion generator moves in the second cross section driven by wind and is sprayed by the liquid outlet device to prevent clogging the filter. The negative oxygen ion generator after sedimentation is driven by the rotating device of the negative oxygen ion generator circulation path to pass through the first drying section for preliminary drying, and complete the final drying through the second drying section to prevent it from remaining in a moist state for a long time and breeding bacteria.

DETAILED DESCRIPTION

[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0028] The illustrations of the filters in the drawings in the specification are only for illustration of their setting positions and working modes. The mesh sizes of each filter cannot represent the actual design sizes, and the ratios between the mesh sizes of each filter cannot be understood as the actual design ratios.

[0029] Now, a negative oxygen ion formaldehyde removal warm air humidification air purifier provided in the embodiment of the present application is described. Figure 1-Figure 4 As shown, a negative oxygen ion formaldehyde removal warm air humidification air purifier includes a body shell and a control system. The body shell is provided with a detachable water tank 5, an air outlet 3, and an air inlet 4. An air purification passage is connected between the air outlet 3 and the air inlet 4. At least one wind supply device is provided in the air purification passage.

[0030] The air purification system further includes an annular negative oxygen ion generator circulation path that intersects the air purification system twice. The air purification system sequentially includes a filtration section 9, a first intersection section 10, a formaldehyde adsorption section 11, a second intersection section 12, and a humidification section 13. The negative oxygen ion generator circulation path 2 sequentially includes a first intersection section 10, a second drying section 15, a second intersection section 12, and a first drying section. A carrier 26 is provided in the negative oxygen ion generator circulation path. The carrier 26 is loaded with particulate negative oxygen ion generator and is provided with a segmented filter 16 that divides the carrier 26 into multiple segments. The side walls of the carrier 26 are provided with a blocking filter 17, and both the inner and outer walls of the carrier 26 are blocking filters 17. The negative oxygen ion generator circulation path is provided with a rotating device to rotate the carrier 26. The humidification section 13 is provided with a liquid outlet device 8 that sprays liquid toward the second intersection section 12. The water tank supplies water to the humidification section 13 through the humidification management 6, and supplies water to the liquid outlet device 8 through the injection pipeline 7.

[0031] The negative oxygen ion formaldehyde removal, warm air humidification air purifier provided in the present application operates under the control of a control system. The air to be purified is sucked into the negative oxygen ion formaldehyde removal, warm air humidification air purifier provided in the present application under the stimulation of a wind power supply device, enters the air purification path through the air inlet, passes through the filter section 9 to filter out larger solid pollutants, and then enters the first intersection section 10. In the first intersection section 10, formaldehyde is removed by a negative oxygen ion generator, and then enters the formaldehyde adsorption section 11, where residual formaldehyde is adsorbed. The air to be purified becomes clean air, and the water vapor carrying negative oxygen ions is removed through the second intersection section 12. The moisture in the composite humidification section 13 and the hot air in the drying section are sent out through the air outlet to obtain warm air with formaldehyde removal and humidification.

[0032] As a feasible implementation method, in this embodiment, the negative oxygen ion generator is tourmaline particles, and the negative oxygen ion generator circulation path exists in the form of a ring, wherein the inner wall and the outer wall are both negative oxygen ion generator carriers that block the filter 17, and the carrier 26 is divided by the segmented filter 16. The negative oxygen ion generator exists in a particulate state, and the increased specific surface area can produce more negative oxygen ions. The air has passed through the filter section to complete preliminary filtration before passing through the negative oxygen ion generator to prevent the negative oxygen ion generator from being covered by dust and dirt. The negative oxygen ion generator moves in the second intersection section 12 driven by wind and is sprayed by the liquid outlet device 8 to prevent it from clogging the filter. The settled negative oxygen ion generator is driven by the rotating device of the negative oxygen ion generator circulation path to pass through the first drying section 14 for preliminary drying, and completes the final drying through the second drying section 15 to prevent it from remaining in a moist state for a long time and breeding bacteria.

[0033] In another embodiment of the present application, Figure 1-3As shown, the control system includes a detection module, a signal transmission module, a display module, a control module, an alarm module, and a power supply. The control module receives information from the detection module and the alarm module. In this embodiment, the detection module includes temperature sensors for monitoring the drying section and the air outlet 3, as well as a liquid level sensor provided in the water tank 5. The control module directly controls and records the status information of the rotating device, the wind power supply device, and the humidification section 13, and displays the information from the sensors and the status information on the display module. When the temperature sensors of the drying section and the air outlet receive a temperature higher than the warning value, or when the liquid level sensor detects that the liquid level is too low, the alarm module provides a light or sound warning and notifies the control module to stop the equipment until the alarm is lifted.

[0034] In another embodiment of the present application, Figure 1 and Figure 3 As shown, the formaldehyde adsorption section 11 includes a detachable activated carbon layer. Although the formaldehyde adsorption section 11 of the negative oxygen ion formaldehyde removal warm wind humidification air purifier provided in this application is arranged after the filter section 9 and the first cross section 10, theoretically the dust particles and formaldehyde content reaching there are relatively rare, but in order to ensure a stronger air purification effect, the formaldehyde adsorption section 11 is designed to be replaceable in this embodiment. The detachable activated carbon layer of the formaldehyde adsorption section 11 connected by the connecting rod 18 can be pulled out and replaced through a handle 19 set on the surface of the negative oxygen ion formaldehyde removal warm wind humidification air purifier.

[0035] In another embodiment of the present application, Figure 3 As shown, the wind supply device is arranged between the filter section 9 and the first intersection section 10. In this embodiment, the wind supply device is a fan 25. The wind supply device is arranged after the filter section 9 to reduce dust contamination of the fan, while being arranged before the first intersection section 10 to reduce the impact of water vapor received.

[0036] In another embodiment of the present application, Figure 3 As shown, the filtration section includes a primary filter 20 and a HEPA filter 21. The primary filter 20 captures larger particles such as dust, hair, and pet dander, while the HEPA (High Efficiency Particulate Air Filter) filter 21 removes tiny particles with a diameter of 0.3 microns and above, including bacteria, viruses, and mold spores.

[0037] In another embodiment of the present application, Figure 3As shown, the outer walls of the first drying section 14 and the second drying section 15 are surrounded by a heating tube 24. As a feasible embodiment, the use of the heating tube surrounding the drying section to dry the negative oxygen ion generator in the drying section, although it generates excess heat loss, can prevent leakage from affecting the operation of other components, thereby enhancing reliability.

[0038] In another embodiment of the present application, Figure 2 and Figure 3 As shown, the detection module includes an outlet air temperature sensor provided at the air outlet 3, a liquid level sensor provided at the water tank 5, and a drying temperature sensor provided at the first drying section 14 and the second drying section 15. The outlet air temperature sensor is used to detect the outlet air temperature of the negative oxygen ion formaldehyde removal warm air humidification air purifier provided in this application to prevent burns. The drying temperature is adjusted in combination with the drying temperature sensors of the first drying section 14 and the second drying section 15 to ensure maximum drying efficiency. The liquid level sensor provided at the water tank 5 is used to remind users to add water. When the water level is too low, the machine is forced to shut down to prevent dry burning.

[0039] In another embodiment of the present application, Figure 3 As shown, a detachable filter cartridge is provided at the air inlet 4. The detachable filter cartridge comprises a filter cartridge frame, a mesh cover 22, and a bottom mesh 23. A detachment sensor is provided at the detachable filter cartridge installation location. Pet-keeping households are increasingly demanding air purifiers, and air purifiers are very susceptible to absorbing pet hair. An easily detachable filter cartridge is provided before the filter section 9 to intercept animal hair and facilitate disassembly and cleaning. After the detachable filter cartridge is removed, the detachment sensor detects that the filter cartridge is not loaded, preventing the air purifier from starting and sucking pet hair deeper into the air, thereby increasing the cleaning workload. This can also reduce filter clogging and reduce the number of times the filter section 9 needs to be disassembled and cleaned.

[0040] In another embodiment of the present application, Figure 4 As shown, the particle size of the negative oxygen ion generator is distributed between 0.3 and 1 mm. In order to allow the negative oxygen ion generator to be fully stirred by the wind, the maximum particle size of the negative oxygen ion generator is set to no more than 1 mm. In order to allow the negative oxygen ion generator to settle quickly without clogging the filter 17, the minimum particle size of the negative oxygen ion generator is set to no less than 0.3 mm. Negative oxygen ion generators within this particle size range can obtain the largest specific surface area without affecting the drying effect, thereby providing the highest negative oxygen ion generation efficiency.

[0041] In another embodiment of the present application, Figure 3 and Figure 4As shown, the mesh diameters of the segmented filter 16 and the blocking filter 17 are both less than 0.27 mm. The blocking filter 17 is primarily used to prevent the negative oxygen ion generator from entering the non-intersection area of ​​the air purification passage 1 under wind force, while the segmented filter 16 is used to prevent the negative oxygen ion generator from moving toward the second intersection section 12 under wind force. Both functions are to limit the migration of the negative oxygen ion generator, and thus their design dimensions are designed based on the particle size of the negative oxygen ion generator. To ensure the stability of the negative oxygen ion generator, the mesh diameters of the segmented filter 16 and the blocking filter 17 are both less than 0.27 mm.

[0042] The above-described embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present application, and should all be included in the scope of protection of the present application.
