Description

Technical Field

[0001] The present application relates to the technical field of air purification, and in particular to a combined formaldehyde removal and odor purifier. Background Art

[0002] Formaldehyde remover and odor purifier, also known as "air cleaner", air freshener or purifier, refers to a product that can absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odor, decoration pollution such as formaldehyde, bacteria, allergens, etc.), and effectively improve the cleanliness of the air.

[0003] The formaldehyde remover and odor purifier in the prior art generally includes a casing, which is provided with an air inlet and an air outlet. A filter device and a fan assembly are arranged inside the casing. When the fan assembly is working, the air outside the casing is sucked into the casing from the air inlet, and is filtered by the filter device and then sent out of the casing from the air outlet.

[0004] However, when replacing the filter device, the formaldehyde remover and odor purifier in the prior art needs to open the casing, take out the old filter device and then replace it with a new filter device, which is inconvenient for users. In addition, due to factors such as the location and size of the air inlet of the casing, the filtering effect of the filter device still needs to be improved. Summary of the invention

[0084] Formaldehyde remover and odor purifier, also known as "air cleaner", air freshener or purifier, refers to a product that can absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odor, decoration pollution such as formaldehyde, bacteria, allergens, etc.), and effectively improve the cleanliness of the air.

[0085] However, when replacing the filter device of the prior art formaldehyde remover, the user needs to open the housing, take out the old filter device and then replace it with a new filter device, which is inconvenient for the user.

[0086] In order to solve this problem, the present application provides a combined formaldehyde removal and odor purifier, which can effectively improve the above-mentioned problem.

[0087] like Figure 1 As shown, a combined formaldehyde remover and odor purifier is an exemplary embodiment of the present application, which includes a filter module 1 and a host module 2.

[0088] like Figure 2 As shown, the filter module 1 is used to filter air. In this embodiment, the filter module 1 includes a filter body 11 and an end cover 12.

[0089] Specifically, the filter body 11 is used to filter air pollutants in the air, and includes activated carbon, filter screen, filter paper, etc. or a combination of activated carbon, filter screen, filter paper, etc., so that the filter body 11 can filter harmful substances such as dust and formaldehyde. In this embodiment, the filter body 11 has a first air inlet surface 111 on the peripheral side, the filter body 11 is hollow and a first airflow channel 112 is formed in the hollow part, and the first airflow channel 112 is connected to the first air inlet surface 111. For example, the filter body 11 is a column as a whole, and the interior of the column is hollow to form the first airflow channel 112; and the column is a loose and porous filter structure, and air can pass through the loose and porous filter structure, so that the filter body 11 forms the first air inlet surface 111, and the first airflow channel 112 is connected to the first air inlet surface 111.

[0090] Specifically, the end cap 12 is disposed at one end of the filter body 11. In this embodiment, the end cap 12 is disposed at the top of the filter body 11. The end cap 12 is provided with a first air outlet 121 connected to the first air channel 112. In this embodiment, the shape of the end cap 12 matches the surface of the top of the filter body 11 to form a circular ring, and the middle of the circular ring forms the first air outlet 121. For example, air can enter the filter module 1 through the first air inlet surface 111, then be filtered by the filter body 11, enter the first air channel 112, and finally be discharged from the filter module 1 from the first air outlet 121.

[0091] like Figure 3 As shown, the host module 2 is used to inhale air and discharge the air into the room. In this embodiment, the host module 2 includes a housing 21, a fan assembly 22, an air duct 23, and an ozone generator 24.

[0092] Specifically, the housing 21 is a cylindrical housing that matches the filter module 11 and is used to accommodate the fan assembly 22. In this embodiment, the housing 21 is provided with a second air inlet 211 and a second air outlet 212, and the housing 21 is provided with a fan assembly 22, and the second air inlet 211 is connected to the first air outlet 121. For example, the top surface of the housing 21 is provided with a second air outlet 212, and the bottom surface is provided with a second air inlet 211. The second air outlet 212 and the second air inlet 211 are both sieve-shaped, which can ensure air circulation while preventing foreign matter from entering; the middle part of the housing 21 is provided with a fan assembly 22, and the fan assembly 22 can work to transport the air from the second air inlet 211 to the second air outlet 212. For example, the fan assembly 22 includes a motor and a fan blade, and the rotation of the motor drives the fan blade to rotate, so that the air can flow from the second air inlet 211 to the second air outlet 212.

[0093] In this embodiment, in order to better purify the air, the purifier further includes an ozone generator 24, which is disposed in the housing 21 and located at the second air inlet 211. The air passing through the second air inlet 211 can carry away ozone or react with ozone to remove bacteria. Specifically, the ozone generator 24 is vertically installed in the housing 21 and extends in the radial direction, so that the ozone generator 24 can contact more air without hindering air circulation.

[0094] Specifically, the air duct 23 is provided in the housing 21 and extends from the second air inlet 211 to the second air outlet 212; the ozone generator 24 and the fan assembly 22 are sequentially arranged in the air duct 23 and along the axial direction from the second air inlet 211 to the second air outlet 212. For example, air enters the host module 2 through the second air inlet 211, and then the air passes through the ozone generator 24 to be sterilized and purified, or ozone is discharged from the second air outlet 212 to the room together with the air through the fan assembly 22.

[0095] In this embodiment, the end cover 12 has a first connection surface 122, and the first air outlet 121 is opened on the first connection surface 122; the housing 21 has a second connection surface 213, and the second air inlet 212 is opened on the second connection surface 213. The filter module 1 and the host module 2 are detachably connected, and when the two are connected, the first and second connection surfaces are engaged, so that the first air outlet 121 and the second air inlet 211 are opposite. Specifically, when the filter module 1 is connected to the host module 2, the first and second connection surfaces are engaged, and the first air outlet 121 and the second air inlet 211 are opposite. At this time, the fan assembly 22 is working, and the indoor air enters the filter module 1 through the first air inlet surface 111, and reaches the first air flow channel 112 after passing through the filter body 11. At this time, the air is purified by passing through the filter body 11. The air is discharged from the filter module 1 through the first air outlet 121 along the first air flow channel 112, and enters the host module 2 through the second air inlet 211 directly opposite to the first air outlet 121, and finally discharged into the room through the second air outlet 212, completing air purification.

[0096] like Figures 4a-4dAs shown, when the user needs to replace the filter device, the user only needs to disassemble the filter module 1 and the host module 2, and then directly reconnect the host module 2 with the new filter module 1, that is, the first and second connection surfaces are engaged, and the filter body 11 can be replaced. In this embodiment, the filter module 1 serves as the base of the host module 2, and the filter module 1 supports the host module 2, so that the user can more conveniently replace the filter device. It should be understood that in other embodiments, the filter module 1 and the host module 2 can also be placed in other relative positions. For example, the host module 2 is a base to support the filter module 1 above the host module 2. When replacing the filter device, it is only necessary to take away the filter module 1 located above and replace it with a new filter module 1; or the filter module 1 and the host module 2 are placed horizontally on the ground. When replacing the filter device, the filter module 1 is separated from the host module 2, and a new filter module 1 is replaced and connected to the host module 2.

[0097] Compared with the prior art, the present application avoids the tedious steps of disassembling and opening the casing, replacing the filter device, and reinstalling the casing, and is more convenient and quick. In addition, the present application does not need to set up a casing, and the air can be directly filtered through the first air inlet surface 111, so that the filtering area is large and the effect is good, and the influence of the position and size of the casing air inlet on the air entering the formaldehyde removal and deodorization device is avoided.

[0098] Preferably, the combined formaldehyde removal and odor purifier also includes a connecting structure 3 for connecting the filter module 1 with the host module 2. Specifically, the connecting structure 3 includes a first connecting member 31 provided on the filter module 1 and a second connecting member 32 provided on the host module 2, and the first and second connecting members are matched and connected together. For example, when the filter module 1 is docked with the host module 2, the first connecting member 31 can fix the second connecting member 32, for example, the first connecting member 31 is a buckle, the second connecting member 32 is a groove, and the first and second connecting members are mutually buckled and connected; for another example, the first connecting member 31 can also be threaded, the second connecting member 32 is a threaded hole, and the first and second connecting members are mutually threaded; for another example, the first connecting member 31 and the second connecting member 32 can also be connected by magnetic attraction.

[0099] like Figure 5 , Figure 6As shown, in this embodiment, the connection structure 3 is a snap-fit ​​structure, which includes a fixing member and a hook tongue, and the fixing member has a recess 311 that cooperates with the hook tongue. In this embodiment, the first connecting member 31 is a fixing member provided on the first connecting surface 122; the second connecting member 32 is a hook tongue provided on the second connecting surface 213. Specifically, the fixing member is provided on the upper surface of the end cover 12, and the recess 311 of the fixing member faces the axis; the hook tongue is provided on the lower surface of the housing 21, and the hook tongue faces the radial direction. When the host module 2 is connected to the filter module 1, the hook tongue hooks the recess 311 of the fixing member, so that the first connecting member 31 is connected to the second connecting member 32, and the filter module 1 is connected to the host module 2. In other embodiments, the first connecting member 31 can also be a hook tongue provided on the first connecting surface 122; the second connecting member 32 is a fixing member provided on the second connecting surface 213. When the host module 2 is connected to the filter module 1 , the hook tongue on the end cover 12 of the filter module 1 hooks the fixing member recess 311 on the host module 2 , so that the first connecting member 31 is connected to the second connecting member 32 , and the filter module 1 is connected to the host module 2 .

[0100] like Figure 7 As shown, in other embodiments, the connection structure 3 is a threaded matching structure, which includes an internal thread and an external thread; wherein the first connection member 31 is an internal thread provided on the filter module 1; correspondingly, the second connection member 32 is an external thread provided on the host module 2. For example, there is a protrusion on the first connection surface 122, and the position of the protrusion facing the axis is provided with an internal thread; the second connection surface 213 is also provided with a protrusion, and the position of the protrusion facing the radial direction is provided with an external thread, the first connection member 31 is the internal thread here, and the second connection member 32 is the external thread here. When the host module 2 is connected to the filter module 1, the external thread of the second connection member 32 is screwed into the internal thread of the first connection member 31, so that the filter module 1 is connected to the host module 2. The number of threads of the internal and external threads can be multiple turns or one turn. Here, the number of threads of the internal and external threads is one turn, so as to reduce the number of rotations and make docking more convenient. In order to facilitate docking and positioning, the length of the external thread can be shortened. For example, the external thread here is a shorter external thread, and the internal thread has a corresponding limit groove. The external thread is first embedded in the limit groove and then tightened with the internal thread. It should be understood that in another embodiment, the first connecting member 31 can also be an external thread provided on the filter module 1; correspondingly, the second connecting member 32 is an internal thread provided on the host module 2. When the host module 2 is connected to the filter module 1, the internal thread of the second connecting member 32 is screwed into the external thread of the first connecting member 31 to achieve the connection between the filter module 1 and the host module 2.

[0101] In other embodiments, the connecting structure 3 can also be a magnetic matching structure, which includes a first magnetic component and a second magnetic component; the first and second magnetic components are both magnets with opposite polarities, or the first magnetic component is a magnet or a metal component, and the second magnetic component is a metal component or a magnet; wherein the first connecting component 31 is a first magnetic component provided on the filter module 1; correspondingly, the second connecting component 32 is a second magnetic component provided on the host module 2. For example, the first connecting member 31 is a magnet provided on the filter module 1, and the second connecting member 32 is a magnet provided on the host module 2. The two magnets have opposite polarities. When the host module 2 is close to the filter module 1, the magnets attract each other, so that the host module 2 and the filter module 1 are connected; for another example, in order to reduce costs, the first connecting member 31 is a metal member provided on the filter module 1, and the second connecting member 32 is a magnet provided on the host module 2. When the host module 2 is close to the filter module 1, the magnet can attract the metal member, so that the host module 2 and the filter module 1 are close to each other and thus complete the connection; for another example, in order to prevent the magnet from generating a magnetic field to interfere with the host module 2, the first connecting member 31 is a magnet provided on the filter module 1, and the second connecting member 32 is a metal member provided on the host module 2. When the host module 2 is close to the filter module 1, the magnet can attract the metal member, so that the host module 2 and the filter module 1 are close to each other and thus complete the connection.

[0102] Further, such as Figure 6 As shown, in this embodiment, the connection structure 3 further includes an operating component 33 for separating the first connection member 31 from the second connection member 32 .

[0103] Specifically, the operating assembly 33 includes an elastic member 331, a fixing seat 332, and an operating member 333. The elastic member 331 can be a spring, rubber, etc., and the operating member 333 is a button. One end of the elastic member 331 is connected to the fixing seat 332, and the other end of the elastic member 331 is connected to the operating member 333. When the user presses the operating member 333, the operating member 333 can overcome the spring force and move. In this example, the operating member 333 is connected to the second connecting member 32. Under the action of external force, the operating member 333 overcomes the elastic force of the elastic member 331 and moves, driving the second connecting member 32 connected thereto to move, so that the first connecting member 31 is separated from the second connecting member 32. For example, the elastic member 331 is a spring, the second connecting member 32 is a hook tongue, and the operating member 333 is disposed on the housing 21 of the host module 2. When the user presses the operating member 333, the operating member 333 overcomes the spring force and moves toward the axial direction, driving the hook tongue connected thereto to also move toward the axial direction, so that the hook tongue is separated from the recess 311 of the fixing member, and the first connecting member 31 is separated from the second connecting member 32. It should be understood that in other embodiments, the connecting structure 3 does not require the operating component 33. For example, in some embodiments, the first connecting member 31 and the second connecting member 32 are connected by threads, and the first connecting member 31 and the second connecting member 32 can be separated or connected only by rotation.

[0104] In other embodiments, the operating member 333 may also be connected to the first connecting member 31. Under the action of external force, the operating member 333 overcomes the elastic force of the elastic member 331 and moves, driving the first connecting member 31 connected thereto to move, so that the first connecting member 31 is separated from the second connecting member 32. For example, the operating member 333 is disposed on the outer surface of the filter module 1 or the end cover 12. When the user presses the operating member 333, the operating member 333 overcomes the elastic force of the elastic member 331 and moves, driving the fixed member connected thereto to move, so that the hook tongue is separated from the recess of the fixed member, so that the first connecting member 31 is separated from the second connecting member 32.

[0105] It should be understood that in other embodiments, when the first connecting member 31 is a hook tongue and the second connecting member 32 is a fixing member, the operating member 333 can still be connected to the first connecting member 31 or the second connecting member 32 in the above manner, thereby driving the hook tongue or the fixing member to move, thereby separating the first connecting member 31 from the second connecting member 32.

[0106] In this embodiment, in order to facilitate the user to use the operating member 333, an operating hole 214 is provided on the housing 21 to accommodate the operating member 333. Specifically, the depth of the operating hole 214 is consistent with the length of the operating assembly 33, so that the outer surface of the housing 21 is flat. When the user uses the operating member 333, the operating member 333 is pressed into the operating hole 214, and the first connecting member 31 is separated from the second connecting member 32.

[0107] In this embodiment, the filter module 1 is provided with two operating components 33, that is, there are two first connecting members 31 and second connecting members 32 connected, so that the filter module 1 is more tightly connected to the host module 2. When the user replaces the filter module 1, the user presses the operating member 333 with both hands and lifts the host module 2 with both hands at the same time, and replaces the host module 2 with the new filter module 1 to complete the replacement.

[0108] It should be understood that in other embodiments, when the connection structure 3 is a threaded matching structure or a magnetic matching structure, the combined formaldehyde removal and odor purifier may also include an operating component 33 to separate the first connection member 31 from the second connection member 32. For example, when the connection structure 3 is a threaded matching structure, the operating component 33 reduces the diameter of the part with the internal thread or expands the diameter of the part with the external thread, so that the first connection member 31 is threadedly separated from the second connection member 32. For example, when the connection structure 3 is a magnetic matching structure, the operating component 33 moves the magnet so that the magnet is separated from the attracted state with the metal part, so that the first connection member 31 is magnetically separated from the second connection member 32. Of course, when the connection structure 3 is a threaded matching structure or a magnetic matching structure, the combined formaldehyde removal and odor purifier may not include the operating component 33. For example, when the connection structure 3 is a threaded matching structure, the user can directly rotate the host module 2 to complete the separation of the internal and external threaded connections, thereby realizing the separation of the first connection member 31 from the second connection member 32. When the connection structure 3 is a magnetic attraction structure, the user applies a force stronger than the magnetic force to enable the host module 2 to move, thereby completing the separation of the magnet-to-magnet or magnet-to-metal connection and realizing the separation of the first connection member 31 and the second connection member 32.

[0109] Preferably, the combined formaldehyde removal and odor purifier further includes a linkage switch 4, which includes a trigger 41, a switch 42 matched with the trigger 41; a circuit module, which is electrically connected to the switch 42; and the host module 2 works when the switch 42 is triggered. For example, the trigger 41 is arranged on the filter module 1, the switch 42 is arranged on the host module 2, and the circuit module is arranged in the housing 21. When the separated filter module 1 is reconnected with the host module 2, the trigger 41 triggers the switch 42, so that the switch 42 transmits an electrical signal to the circuit module, and the circuit module can control the host module 2 to work, thereby avoiding the host module 2 working when the filter module 1 and the host module 2 are not connected, thereby improving safety.

[0110] Specifically, the switch element 42 is a Hall switch or a micro switch. For example, the switch element 42 is a micro switch. Figure 8 , Fig. 9 As shown, the linkage switch 4 includes a convex part and a micro switch, wherein the trigger member 41 is a convex part, and the convex part is arranged on the first connection surface 122, the switch member 42 is a micro switch, and the circuit module is electrically connected to the micro switch. When the separated filter module 1 is reconnected with the host module 2, the first connection surface 31 is close to the second connection surface 213, and the convex part presses the micro switch, so that the micro switch is triggered, and then the micro switch transmits an electrical signal to the circuit module, and the circuit module can control the host module 2 to work.

[0111] Taking the switch element 42 as a Hall switch as an example, the trigger element 41 is a magnet disposed on the first connection surface 122, and the switch element 42 is a Hall switch; the circuit module is electrically connected to the Hall induction switch. When the separated filter module 1 is reconnected with the host module 2, the first connection surface 31 is close to the second connection surface 213, and the magnet is close to the Hall switch, so that the magnetic field around the Hall switch changes, the Hall switch is triggered, and then the Hall switch transmits an electrical signal to the circuit module, and the circuit module can control the host module 2 to work.

[0112] like Fig.10 , Fig.11 As shown, in this embodiment, the purifier also includes: a pre-connection structure 6, which includes a first rail 61 provided on the first connection surface 122 and a second rail 62 provided on the second connection surface 213; the first and second rails cooperate with each other to form a pre-connection structure of the host module 2 and the filter module 1. Specifically, the first rail 61 is an annular protrusion on the first connection surface 122, and the second rail 62 is an annular groove on the second connection surface 213. When the first connection surface 122 contacts the second connection surface 213, the annular protrusion of the first rail 61 can be pre-engaged in the annular groove of the second rail 62, so that the host module 2 can only move within a certain range, which is more convenient for the docking of the filter module 1 and the host module 2.

[0113] like Fig.11 As shown, in this embodiment, the periphery of the second air inlet 211 extends downward to form a pre-joint edge 2111, and the pre-joint edge 2111 can be inserted into the first air outlet 121. Specifically, an annular protrusion extends downward from the periphery of the second air inlet 211, which cooperates with the shape of the first air outlet 121, so that the pre-joint edge 2111 can be inserted into the first air outlet 121, and the host module 2 is limited so that the host module 2 cannot move in the radial direction. When the pre-joint edge 2111 is inserted into the first air outlet 121, the first connecting member 31 and the second connecting member 32 can also complete the connection together, so that the filter module 1 is connected to the host module 2.

[0114] like Fig.12 As shown, in order to facilitate the user to conveniently move the combined formaldehyde removal and deodorizer, the filter module 1 also includes a bottom cover 13 provided at the other end of the filter body 11, and a roller 131 provided on the bottom cover 13. Specifically, the bottom cover 13 is provided at the bottom end of the filter body 11, the bottom cover 13 is fixedly connected to the filter body 11, and a plurality of rollers 131 are provided on the lower surface of the bottom cover 13, and the rollers 131 can move freely, so that the user can conveniently carry the purifier.

[0115] Preferably, in this embodiment, the filter module 1 further comprises a support member disposed on the peripheral side of the filter body 11, and the two ends of the support member are respectively connected to the bottom cover 13 and the end cover 12, so as to provide a supporting force when the host module 2 is placed on the filter module 1. For example, a support member is disposed on the outer surface of the filter body 11, and the two ends of the support member are respectively connected to the bottom cover 13 and the end cover 12, so as to strengthen the supporting force of the filter body, further support the host module 2, and prevent the host module 2 from falling. In other embodiments, a support member may also be disposed in the hollow channel in the filter body 11 to provide a supporting force.

[0116] According to the disclosure and teaching of the above description, those skilled in the art to which the present invention belongs may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the present invention.
