Description

Technical Field

[0001] This utility model relates to the field of air purification and humidification technology, and in particular to an integrated air purification and humidification machine. Background Technology

[0002] Air purifiers purify indoor air by introducing fresh air through a fan or similar structure, filtering the air using an internal filter, and then expelling it.

[0003] Air humidifiers work by drawing water into an atomizing structure within the humidifier, which then atomizes the water into mist, which is then released into the room to humidify the indoor air.

[0004] In some related technologies, air purification and air humidification are achieved using different devices. For example, if you want cleaner air, you need a separate air purifier, and if you want a certain level of humidity in the air, you need a separate humidifier. In this way, at least two devices are needed to achieve air purification and humidification, which takes up a lot of space and is costly.

[0005] In addition, standalone humidifiers humidify by expelling atomized mist. If the indoor air quality is poor, the expelled mist will also be mixed with impurities in the air, resulting in poor air quality after humidification. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

Unless otherwise stated, "a plurality of" means two or more.

[0044] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0045] See Figures 1-10 An integrated air purifier and humidifier includes a body 10, a purification and humidification component 30, and an air inlet component. The body 10 is provided with an air cavity 11, a purification and humidification cavity, an air outlet 13, and an air inlet 14. The air outlet 13 is connected to the air cavity 11, the air outlet 11 is connected to the purification and humidification cavity, and the air inlet 14 is connected to the purification and humidification cavity.

[0046] Specifically, the purification and humidification assembly 30 includes an air filter 31 and an air humidifier. Both the air filter 31 and the air humidifier are installed inside the purification and humidification chamber, and are spaced apart within the chamber. The air filter 31 is located outside the air humidifier, while a humidification space 12 is formed inside the humidifier. The air cavity 11 is connected to the humidification space 12, and the air inlet 14 is connected to the purification and humidification chamber and to the outside of the air filter 31.

[0047] The aforementioned air intake component is located in the air cavity 11. When the air intake component is activated, it can guide the airflow through the air inlet 14 and flow through the air filter 31 and the air humidifier to the humidification space 12 in sequence.

[0048] Based on the above structure, when using the air purifier and humidifier integrated machine of this utility model, the air cavity 11 is located above the purification and humidification cavity. When the air intake component is activated, the air humidifier can perform humidification treatment. The air intake component located in the air cavity 11 guides the airflow through the air outside the machine body 10 into the air inlet 14. Since the air filter 31 is located in the purification and humidification cavity and corresponds to the air inlet 14, the introduced external air can be filtered through the air filter 31, so that the purified air flows to the air humidifier. The mist generated by the air humidifier humidifies the purified air before it enters the humidification space 12. The humidified purified air in the humidification space 12 can be further guided into the air cavity 11 through the air intake component, and then discharged through the air outlet 13 connected to the air cavity 11, thus purifying and humidifying the indoor air and improving the indoor air quality.

[0049] Of course, in other embodiments, when purifying indoor air, the air humidifier can be turned on but the air intake component can operate to guide the external air through the air inlet 14 into the purification and humidification chamber. The external air can then be purified by the air filter 31. The purified air can then enter the humidification space 12. Since the air humidifier can be turned on at this time, the air purification and humidification integrated machine can be directly used as an air purifier.

[0050] Therefore, in this embodiment, by placing both the air filter 31 and the air humidifier inside the purification and humidification chamber, when humidifying the air indoors, the air intake component in the air chamber 11 guides the airflow through the air inlet 14 into the purification and humidification chamber. The airflow is then filtered and humidified before entering the humidification space 12 and exiting through the air outlet 13, thus purifying and humidifying the air. When the air needs to be purified separately, the air humidifier is not activated, allowing the integrated air purification and humidification unit to perform air purification independently, thus achieving dual-purpose functionality.

[0051] Whether humidifying or purifying the air, the airflow passing through the humidifier is purified airflow each time. This reduces the amount of impurities retained on the humidifier, thus preventing issues such as odor and extending the lifespan of the humidifier.

[0052] Of course, in some embodiments, the air filter 31 described above can be directly adopted from the air filter 31 in related technologies. For example, the air filter 31 may include a pre-filter, a HEPA filter and an activated carbon substrate filter. The pre-filter, HEPA filter and activated carbon substrate filter are all porous honeycomb structures, so that air can be purified through the air filter 31.

[0053] Air humidifiers can directly adopt air humidification structures from related technologies. For example, an air humidifier may include a humidifying mesh with a porous honeycomb structure to increase the contact area between water and air. By increasing air humidity through the principle of natural evaporation, air can be humidified through the air humidifier.

[0054] Of course, the aforementioned air humidifier can be an atomizing structure in related technologies, such as an ultrasonic atomizing structure, which uses high-frequency oscillations generated by an ultrasonic transducer to atomize water into ultrafine particles, or a thermal atomizing structure, which uses a heating element to heat the liquid to its boiling point, generating water vapor and releasing it into the air for humidification. The specific structure of the air humidifier can be selected and set according to actual needs.

[0055] As an optional implementation, see [link to implementation details]. Figure 6 as well as Figure 7The aforementioned air humidifier may include a filter frame 32 and a humidifying filter 33. The humidifying filter 33 is arranged around the filter frame 32, and the inner side of the filter frame 32 forms a humidification space 12. Based on this structure, the filter frame 32 is installed in the purification humidification chamber as the mounting base for the humidifying filter 33, allowing the humidifying filter 33 to be arranged around the filter frame 32. When humidifying the air, water needs to be added to the humidifying filter 33. This activates the air intake assembly, guiding the airflow through the air filter 31 for filtration. The purified airflow then passes through the moistened humidifying filter 33, forming a mist-like airflow containing moisture that enters the humidification space 12, then enters the air cavity 11 and is discharged through the air outlet 13.

[0056] It should be noted that if unfiltered airflow is directly guided onto the humidifying filter 33, impurities and dust from the unpurified air will remain, leading to odor and bacterial growth on the humidifying filter 33 over long-term use, thus affecting the quality of the humidified air. Therefore, in this embodiment, the airflow flowing to the humidifying filter 33 is purified by the air filter element 31, thereby reducing odor and improving the quality of air humidification.

[0057] As an optional implementation, see [link to implementation details]. Figure 8 A humidification tank 322 can be provided at the top of the filter frame 32. The humidification tank 322 has multiple water passage holes 323. The multiple water passage holes 323 are distributed in the circumferential direction of the filter frame 32 and guide the water in the humidification tank 322 to the humidification filter 33. With this arrangement, since the humidification filter 33 is surrounded outside the filter frame 32, when humidifying, the water in the humidification tank 322 at the top can flow to the humidification filter 33 through the multiple water passage holes 323 in the axial direction. In this way, the water flow on the humidification filter 33 is evenly distributed. When the air intake component guides the air flow, the air can enter through the circumferentially distributed humidification filter 33, so that the airflow can fully contact the humidification filter 33 and the humidification effect is uniform.

[0058] Of course, since the multiple water passages 323 guide the water in the humidification tank 322 to the humidification filter 33 in an upward circumferential direction, it helps to form a water curtain. When there is gas flowing to the humidification filter 33, it is easier to form mist for humidification, thus the humidification efficiency is higher.

[0059] In related technologies, in addition to directly adding water into the humidification tank 322, the humidification tank 322 can also be connected to an external water pipe, or the following embodiment can be used to guide water flow into the humidification tank 322 for humidification by setting a water tank 15 and a water pump assembly 40 on the body 10.

[0060] In this embodiment, a water tank 15 is provided at the bottom of the body 10, and a water pump assembly 40 is provided in the water tank 15. The water pump assembly 40 is used to guide the water in the water tank 15 to the humidification tank 322. A water return port 121 is provided at the bottom of the purification humidification chamber. The water return port 121 is connected to the bottom of the humidification space 12 and is connected to the water tank 15.

[0061] It should be noted that water can be stored by setting up a water tank 15. The water tank 15 can be connected to the main body of the all-in-one machine by snap-fit ​​or sliding. Users can add water by pulling out the water tank 15.

[0062] Specifically, when using the air humidifier, the water pump assembly 40 is activated, which guides the water in the water tank 15 to the humidification tank 322. After the water flows to the humidification tank 322, it flows through multiple water passages 323 to the humidification filter 33, so that the water flow on the humidification filter 33 comes into full contact with the airflow guided by the air intake assembly to humidify the air.

[0063] Since the water flowing on the humidifying filter 33 may not completely produce mist, or there may be mist in the humidifying space 12 that is not discharged in time and produces water droplets inside, the excess water that remains in the humidifying space 12 or on the humidifying filter 33 can flow to the return water inlet 121 of the humidifying space 12. The return water inlet 121 guides the water flow into the water tank 15 for recycling, thus enabling water recycling and saving water resources.

[0064] Furthermore, the water tank 15 is equipped with an inlet filter 141, which forms a filter chamber within the water tank 15. The water pump assembly 40 is installed within the filter chamber and is used to guide the water in the filter chamber to flow into the humidification tank 322.

[0065] In some embodiments, the water pump assembly 40 includes a water pump 41 and a water guide pipe 41. The water inlet of the water pump 41 is connected to the filter chamber, the water outlet of the water pump 41 is connected to the water guide pipe 41, and the water guide pipe 41 is connected to the humidification tank 322. In this way, when the water pump 41 is started, the filtered water in the filter chamber can be guided into the water guide pipe 41 and then guided to the humidification tank 322 through the water guide pipe 41.

[0066] When humidifying, the water pump 41 is started, which guides the water flow in the water tank 15. The water flows to the inlet filter 141, and after being filtered by the inlet filter 141, it enters the filter chamber. Then, the water pump 41 guides it to the water guide pipe 41. The water flow from the water guide pipe 41 to the humidification tank 322 is the filtered water flow from the filter chamber. When it flows to the humidification filter 33, since the water flow has been filtered and the airflow has also been filtered, the resulting mist is purified mist. Thus, the air quality after humidification and purification is better.

[0067] Furthermore, since the water flowing to the humidifying filter 33 is filtered, this reduces the amount of impurities in the water flowing to the humidifying filter 33, thereby reducing the possibility of the humidifying filter 33 becoming smelly due to the retention of impurities. At the same time, the airflow introduced through the humidifying filter 33 is also filtered, and the water returning to the humidifying filter 33 also has less air impurities mixed in, thus reducing the amount of impurities brought into the water tank 15 by the returning water, and reducing the formation of scale in the water tank 15.

[0068] As an optional implementation, see [link to implementation details]. Figure 6 , Figure 7 as well as Figure 8 To facilitate the assembly of the humidifying filter 33 and the filter frame 32, a first positioning frame 16 can be provided at the top of the filter frame 32, and a second positioning frame 17 can be provided on the bottom wall of the purification humidification chamber. Both the first positioning frame 16 and the second positioning frame 17 can extend in the circumferential direction of the filter frame 32. The first positioning frame 16 is provided with a first positioning groove 161, and the second positioning frame 17 is provided with a second positioning groove 171. When assembling the humidifying filter 33, the top end of the humidifying filter 33 is installed in the first positioning groove 161, and the bottom end of the humidifying filter 33 is installed in the second positioning groove 171. In related technologies, the filter frame 32 can be selected as a support formed by a grid structure. The top and bottom ends of the humidifying filter 33 are installed in a ring with the first positioning groove 161 and the second positioning groove 171, so as to fit against the grid structure of the filter frame 32. When replacing the humidifying filter 33, the top and bottom ends of the humidifying filter 33 can be removed from the corresponding first positioning frame 16 and second positioning frame 17.

[0069] It should be noted that since the humidifying filter 33 is attached and supported by the mesh structure of the filter frame 32, it does not affect the flow of the mist formed on the humidifying filter 33 into the humidifying space 12 enclosed by the filter frame 32. Furthermore, based on this structure, a humidifying tank 322 can be set on the first positioning frame 16, and a water guiding channel 321 can be set on the filter frame 32. The water guiding channel 321 is connected to the water guiding pipe 41 of the water pump assembly 40. After the water pump 41 guides the water flow from the water tank 15 into the water guiding pipe 41, it is then guided through the water guiding channel 321 into the humidifying tank 322 to humidify the humidifying filter 33.

[0070] Of course, the first positioning frame 16 and the second positioning frame 17 can be assembled into the purification and humidification chamber of the body 10 by means of screws, clips and other structures, so as to facilitate subsequent cleaning.

[0071] As an optional implementation, in order to facilitate the positioning and assembly of the air filter 31, a third positioning frame 18 is provided at the top of the purification and humidification chamber, and the third positioning frame 18 is provided with a third positioning groove 181; the second positioning frame 17 is also provided with a fourth positioning groove 191, the fourth positioning groove 191 is located outside the second positioning groove 171, the top of the air filter 31 is installed in the third positioning groove 181; the bottom of the air filter 31 is located in the fourth positioning groove 191.

[0072] It should be noted that, since the air filter 31 and the air humidifier in this embodiment are respectively selected from the filter screen, filter element or filter membrane in related technologies, in order to form a certain filter support strength after assembly, the corresponding filter screen, filter element or filter membrane is unfolded on the top and bottom by the first positioning frame 16, the second positioning frame 17 and the third positioning frame 18 and the fourth positioning frame 19, so that the effective filtration and humidification surface is larger and the assembly structure is stable.

[0073] See Figure 7 In some embodiments, the second positioning frame 17 and the fourth positioning frame 19 are made of an integrally formed positioning plate structure. The second positioning frame 17 and the fourth positioning frame 19 are formed by processing positioning rings, positioning pieces and other structures on the positioning plate structure, and the positioning pieces and positioning rings are used to form corresponding positioning groove structures.

[0074] As an optional implementation, the air outlet 13 is provided with an air outlet assembly, which includes an air outlet main structure 50. The end of the air outlet main structure 50 is provided with a water inlet, which is connected to a water guide, which is connected to a water tank 15. An air outlet is provided around the water inlet, and the water guide and the air outlet are offset from each other in the circumferential direction of the air outlet main structure 50.

[0075] The air intake assembly includes a fan structure 20, which is installed inside the air outlet main body structure 50. There is an air outlet duct 111 between the air outlet main body structure 50 and the fan structure 20. The top end of the air outlet duct 111 is connected to the air outlet section, and the bottom end of the air outlet duct 111 is connected to the humidification space 12.

[0076] The air outlet assembly of this utility model is provided with a water inlet, which is connected to a water guide. The air outlet is located around the water inlet, so when adding water, the user can avoid the air outlet and add water at the air outlet assembly location. Moreover, the fan structure 20 does not need to be stopped during the water adding operation. The air outlet is located around the water inlet, and the water guide and the air outlet are offset in the circumferential direction of the air outlet main structure 50. There is an air outlet duct 111 between the air outlet main structure 50 and the fan structure 20. In this way, when purifying and humidifying the air, the fan mechanism is activated, and air can be generated in the air cavity 11. Negative pressure guides external airflow through the air inlet 14 into the purification and humidification chamber. After entering, the airflow first passes through the air filter 31 to filter the airflow introduced by the air inlet 14. The filtered airflow reaches the air humidifier. Under the guidance of the fan structure 20, the airflow passes through the air humidifier and mixes with the mist generated at the air humidifier before entering the humidification space 12. In this way, the purified and humidified airflow in the humidification space 12 can enter the air cavity 11 and flow through the air cavity 11 to the air outlet duct 111. The air outlet duct 111 guides the airflow to the air outlet section of the main air outlet structure 50 for discharge.

[0077] It should be noted that, since the water inlet is provided with an air outlet, and there is an air outlet duct 111 between the air outlet main structure 50 and the fan structure 20, and the fan structure 20 is provided with an air inlet, when the fan structure 20 is working, the airflow enters the air cavity 11 and is then guided through the air outlet duct 111 to multiple air outlets on the periphery of the air outlet main structure for discharge. This easily forms a rotating airflow and is less likely to become a direct current. Compared with a direct current, the rotating airflow is more comfortable and gentle. For applications that require humidification using airflow, the rotating airflow can reduce the situation of excessively high local humidity.

[0078] Since the water inlet is surrounded by an air outlet, meaning the water inlet is located in the central area of ​​the air outlet, and the central area of ​​the air outlet generally has weaker winds and forms a low-pressure zone, compared to placing the water inlet and the air outlet side by side, having an air outlet around the water inlet can utilize the central area of ​​the air outlet, thereby reducing the impact of the water inlet on the air outlet.

[0079] Since a water guide is installed inside the air outlet duct 111, when the user adds water at the air outlet component, the water is introduced into the water storage section of the air purifier and humidifier integrated machine below through the water inlet and the water guide. The water does not pass through the fan structure 20, and the fan structure 20 and the water guide do not interfere with each other. Therefore, the fan structure 20 does not need to be stopped when adding water, which is convenient for the user.

[0080] The impact of the water guide on the air outlet can be reduced by controlling the shape, size, and number of the water guide. For example, a straight tubular water guide with an outer diameter of 1cm-2cm can be set, and the outer diameter of the main air outlet structure 5010 can be 10cm-20cm.

[0081] Of course, in some embodiments, since a water inlet is provided at the top of the main air outlet structure 50, water can be added directly to the water inlet from the top of the unit 10, and the water guide of the water inlet can guide the water flow into the water tank 15 of the unit 10. Alternatively, the water tank 15 of the unit 10 can be removed directly, and water can be added directly into the water tank 15.

[0082] As an optional implementation, see [link to implementation details]. Figure 4 , Figure 9 as well as Figure 10 The end of the air outlet main structure 50 is provided with a water inlet groove 51; the water inlet groove 51 is formed as a water inlet part;

[0083] The wall of the water inlet groove 51 is provided with a water outlet 511. The water inlet groove 51 is connected to a drain pipe 512 through the water outlet 511. The drain pipe 512 passes through the air duct and extends to the outside of the air outlet main structure 50, forming a water guide section.

[0084] In this embodiment of the utility model, a water inlet groove 51 is provided at the end of the air outlet main structure 50, and the water inlet groove 51 forms a water inlet part.

[0085] When the end of the air outlet main structure 50 is set facing upwards or to the side, the user can directly add water to the water inlet groove 51 from the end of the air outlet main structure 50.

[0086] In this embodiment of the utility model, the groove wall of the water inlet groove 51 is provided with a water guide outlet 511, and the water inlet groove 51 is connected to a drain pipe 512 through the water guide outlet 511. The drain pipe 512 passes through the air duct and extends to the outside of the air outlet main structure 50, and the drain pipe 512 forms a water guide part.

[0087] When the end of the main air outlet structure 50 is set upward, the top of the water inlet groove 51 has an opening for adding water. The water outlet 511 can be set on the side wall or bottom wall of the water inlet groove 51. In order to avoid the water outlet 511 affecting the setting of the fan structure 20, the water outlet 511 is set on the side wall of the water inlet groove 51. When the water outlet 511 is set on the side wall of the water inlet groove 51, in order to facilitate drainage and avoid water accumulation in the water inlet groove 51, the water outlet 511 is set close to the bottom wall of the water inlet groove 51.

[0088] As an optional implementation, see [link to implementation details]. Figure 9 as well as Figure 10 The main air outlet structure 50 includes an air outlet grille, which is arranged around the periphery of the water inlet. Specifically, the air outlet grille includes at least two air guides 53, and two adjacent air guides 53 form an air outlet 52, which forms an air outlet section.

[0089] The extension direction of the air guide vane 53 has an angle α with the axial direction of the air outlet main structure 50.

[0090] In this embodiment of the utility model, the air outlet main structure 50 includes an air outlet grille, which is arranged around the periphery of the water inlet. The air outlet grille includes at least two air guides 53, and two adjacent air guides 53 form an air outlet hole 52, which forms an air outlet. The extension direction of the air guides 53 has an angle α with the axial direction of the air outlet main structure 50.

[0091] Specifically, the air outlet grille has a ring-shaped structure, and the main air outlet structure 50 also includes a main body, which is a hollow sleeve structure. For ease of assembly, the main body is formed by connecting two separate parts. The air outlet grille and the main body can be connected and fixed by means of tight fit, snap-fit, etc. The water inlet groove 51 can be formed by recessing into the main body, or the water inlet groove 51 can be a sleeve structure. The water inlet groove 51 of the sleeve structure can be connected and fixed to the main body by means of tight fit, snap-fit, etc.

[0092] It is understandable that the air outlet formed between two adjacent air guide vanes 53 is a through-hole structure, and multiple air guide vanes 53 are arranged circumferentially at intervals around the water inlet groove 51 to form a multi-hole air outlet structure.

[0093] To facilitate airflow, multiple air guide vanes 53 are arranged circumferentially around the water inlet groove 51. Since the extension direction of the air guide vanes 53 has an angle α with the axial direction of the main air outlet structure 50, and the value of α is in the range of 30°≤a≤60°, the airflow can form a rotating airflow after passing through the air inlet, air duct and air outlet, thereby increasing the air outlet speed and air volume and reducing the air outlet noise.

[0094] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
