TECHNICAL FIELD

[0001] The present application relates to the technical field of air treatment, and in particular to a humidifying filter element and an air humidifying device. BACKGROUND

[0002] Air humidifying devices are widely used in homes, offices and industrial environments to increase the humidity of indoor air. Air humidifying devices increase the humidity of air by introducing moisture into the air. The humidifying filter element, as a key component in the air humidifying device, is responsible for absorbing water and forming a humid air flow, and its performance directly affects the humidifying effect and service life of the air humidifying device.

[0003] The humidifying filter element of the existing air humidifying device is usually fixed inside the air humidifying device by a fixing device.

[0004] However, the humidifying filter element is fixed inside the air humidifying device, which makes it impossible to replace or clean. Once the filter element inside the humidifying filter element is clogged or contaminated, the entire humidifying filter element needs to be replaced, increasing the use cost. Moreover, the humidifying filter element is fixed inside the air humidifying device, which makes it difficult to disassemble and assemble the filter element, increasing the difficulty of maintaining the filter element. CONTENT OF THE INVENTION

[0005] In view of the above problems, the present application provides a humidifying filter element and an air humidifying device, which can solve the problem of difficult disassembly and assembly of the humidifying filter element in the prior art, thereby improving the convenience of maintenance.

[0006] In a first aspect, the present application provides a humidifying filter element for an air humidifying device, comprising: a shell assembly comprising a first shell and a second shell opposite along an axial direction of the humidifying filter element, the first shell and the second shell being detachably connected; and a filter element body connected to the first shell and the second shell respectively, the filter element body being configured to absorb water and form a humid air flow.

[0007] In this way, by providing the detachable first shell and second shell and arranging the filter element body between the first shell and the second shell, the filter element body can be quickly disassembled and cleaned, thereby improving the convenience of maintenance. The user can take out the filter element body from the humidifying filter element and clean or replace it thoroughly, thereby reducing the problems of reduced humidifying effect and shortened service life caused by clogging or contamination of the filter element body. In addition, the detachable design simplifies the replacement process of the filter element body, thereby reducing the use cost of the user.

[0008] In one possible implementation, the shell assembly further comprises a connecting piece arranged on one of the first shell and the second shell and connected to the other.

[0009] Therefore, the stability of the shell assembly can be ensured by the connecting piece. The first shell and the second shell can be quickly assembled and disassembled by the connecting piece, and the convenience of maintenance is improved.

[0010] In a possible implementation, the first shell comprises: a first cylinder portion, the inner side of the first cylinder portion being hollow; a first mounting portion, provided at one end of the first cylinder portion away from the second shell along the axial direction of the humidifying filter element and located at the outer side of the first cylinder portion in the radial direction, one end of the filter element body being arranged in the first mounting portion; and a first connecting portion, provided at one end of the first cylinder portion close to the second shell along the axial direction of the humidifying filter element and located at the inner side of the first cylinder portion in the radial direction, the first connecting portion being configured to be connected with the second shell and the connecting piece.

[0011] Therefore, one end of the filter element body can be arranged in the first mounting portion, so that the stable mounting and positioning of the filter element body can be ensured. The first shell can be tightly matched with the second shell and the connecting piece through the design of the first connecting portion, so that the user can quickly and accurately connect the first shell with the second shell during the installation of the humidifying filter element.

[0012] In a possible implementation, the first mounting portion and the first cylinder portion jointly define a first insertion slot open toward the second shell along the axial direction of the humidifying filter element, and one end of the filter element body is arranged in the first insertion slot.

[0013] Therefore, the first insertion slot can be defined to provide a clear mounting position for the filter element body, so that the filter element body can be quickly and accurately positioned during the installation. The design of the first insertion slot simplifies the installation and disassembly process of the filter element body, and improves the operation convenience of the user.

[0014] In a possible implementation, the second shell comprises: a second cylinder portion, the inner side of the second cylinder portion being hollow; a second mounting portion, provided at one end of the second cylinder portion away from the first shell along the axial direction of the humidifying filter element and located at the outer side of the second cylinder portion in the radial direction, the other end of the filter element body being arranged in the second mounting portion; and a second connecting portion, provided at one end of the second cylinder portion close to the first shell along the axial direction of the humidifying filter element and located at the inner side of the second cylinder portion in the radial direction, the second connecting portion being configured to be connected with the first connecting portion and the connecting piece.

[0015] Thus, by arranging the other end of the filter core body in the second mounting portion, the filter core body can be quickly positioned during installation. The first mounting portion and the second mounting portion of the first shell and the second shell can cooperate with each other to ensure the stability of the position of the filter core body after installation. The first connecting portion and the second connecting portion of the first shell and the second shell can cooperate with each other to further ensure the stability of the filter core body during use.

[0016] In a possible implementation, the second mounting portion and the second cylindrical portion together define a second insertion slot that is open toward the first shell along the axial direction of the humidification filter, and one end of the filter core body is arranged in the second insertion slot.

[0017] Thus, by defining the second insertion slot, a clear installation position is provided for the filter core body, ensuring that the filter core body can be quickly and accurately positioned during installation. The design of the second insertion slot simplifies the installation and disassembly process of the filter core body, improving the operation convenience of the user.

[0018] In a possible implementation, the connecting piece is connected with the second cylindrical portion and passes through the second connecting portion to be connected with the first connecting portion.

[0019] Thus, the connecting piece can ensure the stable connection between the first shell and the second shell. Moreover, the design of the connecting piece also enhances the structural strength of the entire humidification filter, prolonging the service life of the humidification filter.

[0020] In a possible implementation, the connecting piece includes: a connecting ring plate connected with the second cylindrical portion and located on the side of the second connecting portion away from the first connecting portion; a plurality of connecting columns arranged on the side of the connecting ring plate facing the second connecting portion, and the plurality of connecting columns are distributed in the circumferential direction of the connecting ring plate; the first connecting portion is provided with a connecting hole corresponding to each of the connecting columns, and the connecting column passes through the corresponding connecting hole to connect the first shell and the second shell.

[0021] Thus, the plurality of connecting columns on the connecting piece can cooperate with the plurality of connecting holes on the first connecting portion to enable the stable connection of the first shell and the second shell at multiple points, enhancing the stability and structural strength of the humidification filter. Moreover, through the design of the connecting column and the connecting hole, the installation and disassembly process can be simplified, so that the user can easily connect or separate the first shell and the second shell, improving the operation convenience.

[0022] In a possible implementation, the connecting hole is formed as an arc-shaped hole extending along the circumference of the connecting ring plate, the connecting hole comprises a plug-in section and a clamping section, the width of the plug-in section is greater than the width of the clamping section; the connecting column comprises a column body and a clamping head, the diameter of the clamping head is greater than the width of the clamping section and less than the width of the plug-in section, the diameter of the column body is less than the width of the clamping section, the clamping head is adapted to pass through the arc-shaped hole via the plug-in section, and the column body is adapted to move along the clamping section, and the clamping head is clamped with the clamping section.

[0023] In this way, during the installation of the first shell and the second shell, the clamping head can be easily inserted into the connecting hole through the plug-in section, and then moved along the clamping section to the clamping position to achieve quick locking. During the disassembly of the first shell and the second shell, the user can move the clamping head from the clamping section to the plug-in section by a simple operation, and then easily pull out the connecting column from the arc-shaped hole to achieve quick disassembly. In addition, the design of the arc-shaped hole allows the connecting column to move within a certain range, thereby adapting to different assembly errors, and maintaining good connection performance even after multiple assembly and disassembly.

[0024] In a possible implementation, the first connecting part is further provided with a limiting groove, and the limiting groove is located on one side of the connecting hole in the circumferential direction; the connecting column further comprises a limiting buckle adapted to be buckled to the limiting groove.

[0025] In this way, the matching design of the limiting buckle and the limiting groove can ensure the stability of the connecting column after installation, prevent accidental loosening caused by vibration or external force during use, and improve the reliability of the connection.

[0026] In a possible implementation, the side of the second connecting part facing away from the first connecting part is provided with a first step surface and a second step surface, the first step surface is located on the radially inner side of the second step surface and on the side of the second step surface close to the second connecting part; the connecting ring plate has a first step portion abutting against the first step surface and a second step portion abutting against the second step surface.

[0027] In this way, the abutting design of the first step portion and the second step portion with the first step surface and the second step surface ensures accurate positioning and stable connection of the connecting piece during installation, and avoids deviation and misplacement during installation. Moreover, the matching design of the step surface and the step portion ensures the stability of the connecting piece after installation, prevents accidental loosening caused by vibration or external force during use, and improves the reliability of the connection.

[0028] In a possible implementation, the inner wall of the second cylindrical portion is provided with a clamping protrusion, a fixing groove is defined between the clamping protrusion and the second step surface, and the second step portion is fixed in the fixing groove.

[0029] In this way, by arranging the clamping protrusion, support can be provided to the connecting piece in the axial direction of the humidifying filter element, effectively dispersing the stress received by the connecting piece during use and reducing the risk of damage to the clamping joint caused by excessive stress.

[0030] In a possible implementation, the side of the clamping protrusion facing away from the second step surface is provided with a first guide slope; the second step portion is provided with a second guide slope parallel to the first guide slope; and the second step portion is clamped into the fixing groove by cooperation of the first guide slope and the second guide slope.

[0031] In this way, by cooperation of the first guide slope and the second guide slope, the second step portion of the connecting piece can be smoothly slid into the fixing groove during installation, reducing the resistance during installation and improving the convenience and efficiency of installation. Moreover, the design of the guide slope reduces the friction between the second step portion and the clamping protrusion, reducing wear during installation and disassembly and prolonging the service life of the connecting piece.

[0032] In a possible implementation, the first mounting portion is formed with an air outlet grille.

[0033] In this way, the design of the air outlet grille ensures uniform distribution of air flowing out of the filter element body, avoiding poor humidification caused by uneven local air outlet, and improving the uniformity of humidification. The air outlet grille can also play a certain protective role, preventing fingers or other objects from directly contacting the filter element body and improving the use safety of the equipment. In addition, the design of the air outlet grille helps to optimize the airflow path, reduce airflow resistance, and ensure smooth airflow through the filter element body, improving the humidification effect.

[0034] In a possible implementation, the first shell further includes a partition plate arranged on the inner side of the first cylindrical portion and located on the side of the first connecting portion away from the second shell, the partition plate and the first cylindrical portion together defining a top-open split chamber for receiving water in the water storage tank; and the first cylindrical portion is provided with a plurality of split holes distributed along the circumferential direction thereof, and water in the split chamber seeps into the filter element body through the split holes.

[0035] In this way, the split chamber formed by the partition plate and the first cylindrical portion can uniformly receive water in the water storage tank, ensuring uniform distribution of water flow. The design of the plurality of split holes allows water to seep uniformly into the filter element body, improving the uniformity of humidification.

[0039] Therefore, the water storage tank is arranged on the upper side of the humidification filter core, and the water is naturally flowed to the humidification filter core by gravity, which can simplify the waterway design, reduce energy consumption and maintenance cost. The humidification filter core is arranged on the upper side of the airflow driving device, which ensures that the air can fully absorb moisture when passing through the humidification filter core, improving the humidification effect. In addition, the upper design of the water storage tank makes the water adding operation more convenient, and the user can easily add or replace the water source, which can adapt to different use environments and needs.

[0065] The specific embodiments have been shown and described in the foregoing drawings and specification, it is to be understood that the application is not limited to the embodiments disclosed, but instead can be practiced with the scope of the claims. It is intended to cover any adaptations or variations of the specific embodiments discussed herein. Therefore, it is manifestly intended that this application be limited only by the following claims and equivalents thereof. DETAILED DESCRIPTION

[0066] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The same reference numbers in different drawings represent the same or similar elements. The embodiments described in the following examples do not represent all of the ways in which the application can be practiced. Rather, they are merely illustrative of the ways in which the application can be practiced.

[0067] The humidifying filter core of the existing air humidifying device is usually fixed in the air humidifying device by a fixing device. However, the humidifying filter core is fixed in the air humidifying device, which causes it to be unable to be replaced or cleaned. Once the filter core inside the humidifying filter core is blocked or contaminated, the whole humidifying filter core needs to be replaced, which increases the use cost. In addition, the humidifying filter core is fixed in the air humidifying device, which causes the filter core to be difficult to disassemble and assemble, and increases the difficulty of maintaining the filter core.

[0068] Therefore, the humidifying filter element and the air humidifying device are provided, the humidifying filter element is designed as a detachable shell assembly, the first shell and the second shell of the shell assembly are detachably connected through the connecting piece, the quick assembly and disassembly of the humidifying filter element can be realized, and the convenience of maintenance is improved. Through the detachable design, the user can easily take out the filter element body from the humidifying filter element and perform complete cleaning or replacement, and problems of reduced humidifying effect and shortened service life caused by blockage or pollution of the filter element body are reduced. In addition, the detachable design simplifies the replacement process of the filter element body, and reduces the use cost of the user.

[0069] It can be understood that the air humidifying device can be a steam humidifier, an ion humidifier or a hybrid humidifier.

[0070] When the air humidifying device works, dry air from the outside can enter the inside of the casing of the air humidifying device through the air inlet. The airflow driving device (such as a fan or a blower) inside the air humidifying device can drive the air flow and pass through the humidified humidifying filter element. When the dry air flows through the humidified filter element, water molecules evaporate from the surface of the filter element into the airflow, thereby increasing the humidity of the air. The humidified air is discharged through the air outlet of the casing and enters the room to improve the air humidity in the room.

[0071] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail in the following specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of the present application will be described below with reference to the drawings:

[0072] Reference Figure 1 The air humidifying device 1 provided by the present application can be a mist-free humidifier or other type of humidifier. The air humidifying device 1 comprises a main machine 20, a humidifying filter element 10, an airflow driving device and a water storage tank 30.

[0073] The main machine 20 is the supporting structure of the whole air humidifying device 1, and contains the airflow driving device of the air humidifying device 1. The airflow driving device is used to drive the airflow to be discharged after passing through the air inlet 202 and the humidifying filter element 10 in sequence, so as to ensure that the dry air can be humidified by the humidifying filter element 10. The airflow driving device can be a fan, a blower or the like, and the present application does not make specific limitation. The water storage tank 30 can supply water for the humidifying filter element 10, so as to ensure that the humidifying filter element 10 can continuously absorb water and form humidified airflow.

[0074] The main machine 20 further comprises a casing 201. The humidifying filter 10 is detachably arranged in the casing 201. The casing 201 of the main machine 20 is provided with an air inlet 202 through which dry air from the outside can enter the air humidifying device 1. The air inlet 202 can be arranged at the bottom of the side wall of the casing 201. Alternatively, the air inlet 202 can be arranged at the middle of the side wall of the casing 201. Alternatively, the air inlet 202 can be arranged at the top of the casing 201. Alternatively, the air inlet 202 can be arranged at multiple positions of the casing 201, such as the bottom, the middle and the top of the side wall of the casing 201.

[0075] It can be understood that the humidifying filter 10 is detachably arranged in the casing 201, so that the user can maintain and replace the humidifying filter 10. In addition, the user can also take out the filter in the humidifying filter 10 for thorough cleaning or replacement, thereby reducing the problem of reduced humidifying effect and shortened service life caused by filter blockage or pollution. In addition, the detachable design simplifies the replacement process of the humidifying filter 10 and reduces the use cost of the user.

[0076] In a possible implementation, referring to Figure 1 、 Figure 2 , the water storage tank 30 of the air humidifying device 1 is arranged at the upper side of the air humidifying device 1. The air inlet 202 of the air humidifying device 1 is arranged at the bottom of the side wall of the air humidifying device 1. The humidifying filter 10 and the airflow driving device can be arranged between the water storage tank 30 and the air inlet 202. Specifically, the humidifying filter 10 is located at the upper side of the airflow driving device, and the humidifying filter 10 is close to the water storage tank 30. The airflow driving device is arranged inside the casing 201 and close to the air inlet 202. In this way, the water in the water storage tank 30 arranged at the upper side of the air humidifying device 1 can flow to the humidifying filter 10 under the action of gravity.

[0077] It can be understood that the water storage tank 30 is arranged at the upper side of the humidifying filter 10, and the water is naturally flowed to the humidifying filter 10 by the action of gravity, which can simplify the waterway design and reduce energy consumption and maintenance cost. The humidifying filter 10 is arranged at the upper side of the airflow driving device, which ensures that the air can fully absorb moisture when passing through the humidifying filter 10, thereby improving the humidifying effect. In addition, the upper design of the water storage tank 30 makes the water adding operation more convenient, and the user can easily add or replace the water source, which can adapt to different use environments and requirements.

[0078] Referring to Figure 2 、 Figure 3 、 Figure 4The humidifying filter element 10 provided by the utility model, which comprises a shell assembly 100 and a filter element body 200. The shell assembly 100 is used for containing and fixing the filter element body 200. Further, the shell assembly 100 comprises a first shell 110 and a second shell 120, and the first shell 110 and the second shell 120 are detachably connected. For example, the first shell 110 and the second shell 120 can be connected through buckling; or the first shell 110 and the second shell 120 can be connected through screw threads; or the first shell 110 and the second shell 120 can be connected through elastic clamps, of course, the present application does not limit this. The first shell 110 and the second shell 120 are oppositely arranged along the axial direction of the humidifying filter element 10. In this way, the filter element body 200 can be arranged between the first shell 110 and the second shell 120 and connected with the first shell 110 and the second shell 120 respectively.

[0079] The filter element body 200 can be made of synthetic fibers, fiber cotton, non-woven fabric and the like, so that the filter element body 200 has good water absorption, thereby effectively absorbing moisture and forming a humid air flow. Moreover, the filter element body 200 made of the above-mentioned materials can be washed with water and reused after drying. It can be understood that by arranging the detachable first shell 110 and the second shell 120 and arranging the filter element body 200 between the first shell 110 and the second shell 120, the filter element body 200 can be quickly disassembled and cleaned, improving the convenience of maintenance. The user can take out the filter element body 200 from the humidifying filter element 10 and clean or replace it thoroughly, reducing the problem of reduced humidification effect and shortened service life caused by blockage or pollution of the filter element body 200. In addition, the detachable design simplifies the replacement process of the filter element body 200, reducing the user's use cost.

[0080] In a possible implementation, the shell assembly 100 further comprises a connecting piece 130. The connecting piece 130 is used for connecting the first shell 110 and the second shell 120. The connecting piece 130 can be arranged on the first shell 110, and the first shell 110 can be connected with the second shell 120 through the connecting piece 130 thereon. Alternatively, the connecting piece 130 can be arranged on the second shell 120, and the second shell 120 can be connected with the first shell 110 through the connecting piece 130 thereon. Alternatively, the connecting piece 130 is an independent component and can be separately installed between the first shell 110 and the second shell 120.

[0081] Optionally, the connecting member 130 can be a snap-fit connecting member, a screw-fixed connecting member or a ring-shaped connecting member. For example, the connecting member 130 can be a snap-fit connecting member. The snap-fit connecting member can include a snap and a slot. The snap is arranged on the first shell 110, and the slot is arranged on the second shell 120 and cooperates with the snap. Specifically, during installation, the snap on the first shell 110 can be aligned with the slot on the second shell 120, and the snap can be embedded in the slot by pressing.

[0082] It can be understood that the stability of the shell assembly 100 can be ensured by arranging the connecting member 130. The user can quickly assemble and disassemble the first shell 110 and the second shell 120 through the connecting member 130, thereby improving the convenience of maintenance.

[0083] In a possible implementation, referring to Figure 4 、 Figure 5 、 Figure 9 The first shell 110 includes a first cylinder portion 111, a first mounting portion 112 and a first connecting portion 113. Specifically, the inner side of the first cylinder portion 111 is hollow. The inner side of the first cylinder portion 111 can be provided with a water feeding mechanism. The water feeding mechanism can be connected with the water storage tank 30 located on the upper side of the air humidifying device 1.

[0084] Optionally, the water feeding mechanism can be a float ball valve type water feeding mechanism, an electromagnetic valve type water feeding mechanism, a capillary tube type water feeding mechanism, etc. For example, the water feeding mechanism can be a float ball valve type water feeding mechanism. The float ball valve type water feeding mechanism can include a float ball, a lever and a valve. The float ball is located in the water storage tank 30, and the float ball can float up and down with the change of water level. The float ball is connected with the valve of the water storage tank 30 through the lever. When the water level drops, the float ball drops, and the float ball opens the valve through the lever, so that the water in the water storage tank 30 flows into the filter core body 200; when the water level rises to a certain height, the float ball rises, and the valve is closed through the lever, thereby stopping water feeding. The type of the water feeding mechanism can be determined according to actual needs, and the present application does not make any limitation.

[0085] Further, the first mounting portion 112 and the first connecting portion 113 are distributed along the axial direction of the humidifying filter core 10. The first mounting portion 112 is located at one end of the first cylinder portion 111, and the first connecting portion 113 is located at the other end of the first cylinder portion 111. The first mounting portion 112 is away from the second shell 120 and located on the radial outer side of the first cylinder portion 111. One end of the filter core body 200 can be arranged on the first mounting portion 112. The first connecting portion 113 is close to the second shell 120 and located on the radial inner side of the first cylinder portion 111. The first connecting portion 113 is used for connecting with the second shell 120 and the connecting member 130.

[0086] It can be understood that by arranging one end of the filter core body 200 at the first mounting portion 112, the stable installation and positioning of the filter core body 200 can be ensured. By designing the first connecting portion 113, the first shell 110 can be tightly matched with the second shell 120 and the connecting piece 130, so that the user can quickly and accurately connect the first shell 110 with the second shell 120 during the installation of the humidification filter core 10.

[0087] In a possible implementation, referring to Figure 9 、 Figure 10 , the first mounting portion 112 and the first barrel portion 111 form a first insertion slot 114. The opening of the first insertion slot 114 faces the second shell 120. The first insertion slot 114 is used for inserting one end of the filter core body 200. The entrance edge of the first insertion slot 114 is designed with a smooth bevel or chamfer, so that the filter core body 200 can be easily and accurately inserted. The size of the first insertion slot 114 can match the outer contour of one end of the filter core body 200, so as to ensure that the filter core body 200 can be stably fixed in the first shell 110 after being inserted into the first insertion slot 114.

[0088] It can be understood that by defining the first insertion slot 114, an installation position can be provided for the filter core body 200, so as to ensure that the filter core body 200 can be quickly and accurately positioned during installation. The design of the first insertion slot 114 simplifies the installation and disassembly process of the filter core body 200, and improves the operation convenience of the user.

[0089] In a possible implementation, referring to Figure 4 、 Figure 5 、 Figure 9 , the second shell 120 includes a second barrel portion 121, a second mounting portion 122, and a second connecting portion 123. Specifically, the inner side of the second barrel portion 121 is hollow. The radial dimension of the second barrel portion 121 is the same as that of the first barrel portion 111. In order to ensure the stability and durability of the humidification filter core 10, a support structure such as a support rib, a support ring, etc. can be arranged inside the second barrel portion 121.

[0090] Further, the second mounting portion 122 and the second connecting portion 123 are distributed along the axial direction of the humidifying filter element 10. The second mounting portion 122 is located at one end of the second cylinder portion 121, and the second connecting portion 123 is located at the other end of the second cylinder portion 121. The second mounting portion 122 is away from the first shell 110 and located at the radial outer side of the second cylinder portion 121. The other end of the filter element body 200 can be arranged at the second mounting portion 122. The second mounting portion 122 can include a ring plate and a bottom plate. The ring plate is distributed along the circumferential direction of the second cylinder portion 121 to form a ring structure around the outside of the second cylinder portion 121. The bottom plate connects the ring plate and the bottom of the second cylinder portion 121, and the ring plate and the bottom plate jointly constitute the second mounting portion 122. The second connecting portion 123 is close to the first shell 110 and located at the radial inner side of the first cylinder portion 111.

[0091] The second connecting portion 123 is used to connect with the first shell 110 and the connecting piece 130.

[0092] Optionally, the first connecting portion 113 of the first shell 110 and the second connecting portion 123 of the second shell 120 and the connecting piece 130 can be connected by thread connection, buckle connection, pin connection, etc. For example, the first connecting portion 113 and the second connecting portion 123 and the connecting piece 130 can be connected by thread connection. Specifically, threads can be arranged on the outer surfaces of the first connecting portion 113 and the second connecting portion 123, and matching threads can be correspondingly arranged on the outer surface of the connecting piece 130. During installation, the connecting piece 130 is arranged between the first connecting portion 113 and the second connecting portion 123, and the connection between the first shell 110 and the second shell 120 is realized by rotating the connecting piece 130.

[0093] It can be understood that by arranging the other end of the filter element body 200 at the second mounting portion 122, the rapid positioning of the filter element body 200 during installation can be realized. The first mounting portion 112 and the second mounting portion 122 of the first shell 110 and the second shell 120 can cooperate with each other to ensure the position stability of the filter element body 200 after installation. The first connecting portion 113 and the second connecting portion 123 of the first shell 110 and the second shell 120 can cooperate with each other to further ensure the stability of the filter element body 200 during use.

[0094] In a possible implementation, referring to Figure 9 、 Figure 10 A second insertion slot 124 is formed between the second mounting portion 122 and the second cylinder portion 121. The opening of the second insertion slot 124 faces the first shell 110. The second insertion slot 124 is used to insert the other end of the filter element body 200.

[0095] It can be understood that by defining the second slot 124, a clear mounting position can be provided for the filter core body 200, ensuring that the filter core body 200 can be quickly and accurately positioned during installation. The design of the second slot 124 simplifies the installation and removal process of the filter core body 200, improving the operational convenience of the user.

[0096] Optionally, the size of the first shell 110 can be greater than the size of the second shell 120. Preferably, the size of the first slot 114 is greater than the size of the second slot 124. Thus, the filter core body 200 can be a ring structure with a gradually changing inner diameter. The inner diameter of the upper ring structure of the filter core body 200 is greater than the inner diameter of the lower ring structure. Further, the first shell 110 can be connected with the upper ring structure of the filter core body 200, and the second shell 120 can be connected with the lower ring structure of the filter core body 200.

[0097] In a possible implementation, referring to Figure 5 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 The connecting piece 130 is connected with the second cylinder part 121. After the connecting piece 130 is connected with the second cylinder part 121, part of the structure of the connecting piece 130 can pass through the second connecting part 123 and be connected with the first connecting part 113. The connecting piece 130 can be fixedly connected with the second cylinder part 121. For example, the connecting piece 130 can be directly welded, riveted or screwed on the second cylinder part 121 to ensure the firmness of the connection. Alternatively, the connecting piece 130 can be movably connected with the second cylinder part 121. For example, the connecting piece 130 is snap-connected, screw-connected with the second cylinder part 121. Optionally, the connecting piece 130 can be connected with the second cylinder part 121 through a connecting disc, a connecting frame, a connecting block, a connecting rod or the like.

[0098] It can be understood that the connecting piece 130 can ensure the stable connection between the first shell 110 and the second shell 120. Moreover, the design of the connecting piece 130 also enhances the structural strength of the entire humidifying filter core 10, prolonging the service life of the humidifying filter core 10.

[0099] In a possible implementation, referring to Figure 5 、 Figure 9 、 Figure 9 、 Figure 10 、 Figure 11The connecting piece 130 comprises a connecting ring plate 131 and a plurality of connecting columns 132. The plurality of connecting columns 132 are located on one side of the connecting ring plate 131. Moreover, the plurality of connecting columns 132 are distributed along the circumference of the connecting ring plate 131. The connecting ring plate 131 of the connecting piece 130 can be movably connected with the second cylinder portion 121. Moreover, the connecting ring plate 131 is located on the side of the second connecting portion 123 which is away from the first connecting portion 113. In this way, the plurality of connecting columns 132 on the connecting ring plate 131 can pass through the second connecting portion 123 and be connected with the first connecting portion 113. In order to realize the connection between the first connecting portion 113 and the plurality of connecting columns 132, the first connecting portion 113 is provided with a plurality of connecting holes 1131 corresponding to the plurality of connecting columns 132. When the connecting ring plate 131 is connected with the second cylinder portion 121, the connecting columns 132 can pass through the corresponding connecting holes 1131 to realize the connection between the first shell 110 and the second shell 120. Alternatively, the plurality of connecting columns 132 are distributed along the circumference of the connecting ring plate 131.

[0100] In a possible design, the connecting piece 130 can further comprise a connecting ring plate 131 and a plurality of buckles. The plurality of buckles are located on one side of the connecting ring plate 131. Moreover, the plurality of buckles are uniformly distributed along the circumference of the connecting ring plate 131. The connecting piece 130 can be connected with the plurality of buckle slots on the first connecting portion 113 through the plurality of buckles of the connecting ring plate 131. Alternatively, the connecting piece 130 can further comprise a connecting ring plate 131 and a plurality of hooks located on one side of the connecting ring plate 131. The connecting piece 130 can be connected with the plurality of locking buckles on the first connecting portion 113 through the plurality of hooks of the connecting ring plate 131.

[0101] It can be understood that the plurality of connecting columns 132 on the connecting piece 130 can be matched with the plurality of connecting holes 1131 on the first connecting portion 113, so that the first shell 110 and the second shell 120 are firmly connected at a plurality of points, thereby enhancing the stability and structural strength of the humidifying filter element 10. Moreover, through the design of the connecting columns 132 and the connecting holes 1131, the installation and disassembly process can be simplified, so that the user can easily connect or separate the first shell 110 and the second shell 120, thereby improving the convenience of operation.

[0102] In a possible implementation, with reference to Figure 6 , Figure 12The connecting hole 1131 includes a plug-in section 1131a and a clamping section 1131b. The width of the plug-in section 1131a is greater than the width of the clamping section 1131b. The larger width of the plug-in section 1131a can serve as a guide part to help the connecting column 132 smoothly enter the connecting hole 1131. The smaller width of the clamping section 1131b can wrap the connecting column 132 to prevent it from loosening or falling off during use, ensuring the stability and reliability of the connection. Because the width of the plug-in section 1131a is greater than the width of the clamping section 1131b, the connecting hole 1131 is formed as an arc-shaped hole extending along the circumference of the connecting ring plate 131.

[0103] Further, the connecting column 132 includes a column body 1321 and a clamping head 1322. The diameter of the clamping head 1322 is greater than the width of the clamping section 1131b and less than the width of the plug-in section 1131a. The diameter of the column body 1321 is less than the width of the clamping section 1131b. In this way, in the specific implementation process, the clamping head 1322 of the connecting column 132 can pass through the arc-shaped hole through the plug-in section 1131a, and the column body 1321 of the connecting column 132 can move along the clamping section 1131b under the action of external force to make the clamping head 1322 and the clamping section 1131b clamped and matched, and because the diameter of the clamping head 1322 is greater than the width of the clamping section 1131b, the locking is achieved.

[0104] It can be understood that in the installation process of the first shell 110 and the second shell 120, the clamping head 1322 can be easily inserted into the connecting hole 1131 through the plug-in section 1131a, and then moved to the clamping position along the clamping section 1131b to achieve quick locking. In the disassembly process of the first shell 110 and the second shell 120, the user can move the clamping head 1322 from the clamping section 1131b to the plug-in section 1131a by simple operation, and then easily pull out the connecting column 132 from the arc-shaped hole to achieve quick disassembly. In addition, the design of the arc-shaped hole allows the connecting column 132 to move within a certain range, which can adapt to different assembly errors, and even after multiple assembly and disassembly, it can maintain good connection performance.

[0105] In a possible implementation, with reference to Figure 6 , Figure 12In order to realize the stable connection between the connecting piece 130 and the first connecting part 113, the first connecting part 113 is further provided with a limiting groove 1132. The connecting column 132 is further provided with a limiting buckle 1323. The limiting groove 1132 cooperates with the limiting buckle 1323. After the clamping head 1322 and the clamping section 1131b are clamped and cooperated, the limiting buckle 1323 can be buckled in the limiting groove 1132 to realize further locking. Specifically, the limiting groove 1132 is a plurality of limiting grooves corresponding to the connecting holes 1131. The limiting groove 1132 is located on one side of the connecting hole 1131 in the circumferential direction. The limiting buckle 1323 can also be a plurality of limiting buckles corresponding to the limiting grooves 1132.

[0106] It can be understood that the cooperation design of the limiting buckle 1323 and the limiting groove 1132 can ensure the stability of the connecting column 132 after installation, prevent accidental loosening due to vibration or external force during use, and improve the reliability of the connection.

[0107] In a possible implementation, referring to Figure 8 、 Figure 9 、 Figure 10 The second connecting part 123 is provided with a first step surface 1231 and a second step surface 1232 on one side. Specifically, the first step surface 1231 and the second step surface 1232 are located on the side of the second connecting part 123 away from the first connecting part 113. Further, the second step surface 1232 is closer to the filter core body 200 than the first step surface 1231.

[0108] In order to realize the stable contact between the connecting piece 130 and the second connecting part 123, the connecting ring plate 131 of the connecting piece 130 is provided with a first step part 1311 and a second step part 1312. After the connecting piece 130 is connected with the second cylinder part 121, the first step part 1311 of the connecting piece 130 can abut against the first step surface 1231, and the second step part 1312 of the connecting piece 130 can abut against the second step surface 1232.

[0109] It can be understood that the abutment design of the first step part 1311 and the second step part 1312 with the first step surface 1231 and the second step surface 1232 ensures the accurate positioning and stable connection of the connecting piece 130 during installation, avoids deviation and misplacement during installation, and ensures the stability of the connecting piece 130 after installation, prevents accidental loosening due to vibration or external force during use, and improves the reliability of the connection.

[0110] In a possible implementation, referring to Figure 7 、 Figure 8 、 Figure 10The inner wall of the second cylinder portion 121 is provided with a clamping protrusion 1211. Optionally, the clamping protrusion 1211 is a plurality of protrusions distributed circumferentially along the inner wall of the second cylinder portion 121. The clamping protrusion 1211 and the second step surface 1232 can define a fixing groove. The second step portion 1312 of the connecting piece 130 can be fixed in the fixing groove. When the connecting piece 130 is connected to the second cylinder portion 121, a force in the axial direction of the second cylinder portion 121 can be applied to the connecting piece 130, so that the second step portion 1312 of the connecting piece 130 passes through the clamping protrusion 1211 and enters the fixing groove, thereby achieving stable connection between the connecting piece 130 and the second cylinder portion 121.

[0111] Alternatively, the second step portion 1312 of the connecting piece 130 can be provided with a plurality of notches corresponding to the clamping protrusion 1211. When the connecting piece 130 is connected to the second cylinder portion 121, the notches on the second step portion 1312 can be aligned with the clamping protrusion 1211, so that the second step portion 1312 enters the fixing groove, and then the second step portion 1312 is rotated to misalign the notches with the clamping protrusion 1211, thereby achieving stable connection between the connecting piece 130 and the second cylinder portion 121. Further, a rotating handle can be arranged on the side of the second step portion 1312 away from the second step portion 1312, so as to facilitate rotation of the second step portion 1312.

[0112] It can be understood that by arranging the clamping protrusion 1211, the connecting piece 130 can be provided with support in the axial direction of the humidifying filter element 10, effectively dispersing the stress received by the connecting piece 130 during use and reducing the risk of damage to the clamping joint 1322 due to excessive stress.

[0113] In a possible implementation, referring to Figure 8 、 Figure 10 The side of the clamping protrusion 1211 away from the second step surface 1232 is provided with a first guide inclined surface 1211a. The second step portion 1312 is provided with a second guide inclined surface 1312a. In order to facilitate the second step portion 1312 to enter the fixing groove, the first guide inclined surface 1211a should be parallel to the second guide inclined surface 1312a, so that the second step portion 1312 can be clamped into the fixing groove through cooperation of the first guide inclined surface 1211a and the second guide inclined surface 1312a. The inclination angles of the first guide inclined surface 1211a and the second guide inclined surface 1312a can be determined according to actual needs, which are not limited in the present application.

[0114] It can be understood that through the matched design of the first guide slope 1211a and the second guide slope 1312a, the second stepped portion 1312 of the connecting piece 130 can smoothly slide into the fixing groove during installation, reducing the resistance during installation and improving the convenience and efficiency of installation. Moreover, the design of the guide slope reduces the friction between the second stepped portion 1312 and the clamping convex portion 1211, reduces the wear during installation and disassembly, and prolongs the service life of the connecting piece 130.

[0115] In a possible implementation, referring to Figure 4 、 Figure 5 、 Figure 7 、 Figure 9 、 Figure 10 , the first mounting portion 112 is formed with an air outlet grille 1121.

[0116] It can be understood that the design of the air outlet grille 1121 ensures uniform distribution of air flowing out of the filter core body 200, avoids poor humidification effect caused by local air outlet unevenness, and improves the uniformity of humidification. The air outlet grille 1121 can also play a certain protection role to prevent fingers or other objects from directly contacting the filter core body 200, thereby improving the use safety of the equipment. In addition, the design of the air outlet grille 1121 helps to optimize the airflow path, reduce airflow resistance, and ensure smooth airflow through the filter core body 200, thereby improving the humidification effect.

[0117] In a possible implementation, referring to Figure 5 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 , the first shell 110 further includes a partition plate 115. The partition plate 115 is located on the inner side of the first cylinder portion 111 and on the side of the first connecting portion 113 away from the second shell 120. The partition plate 115 and the first cylinder portion 111 can form a top-open split chamber. Further, the partition plate 115 can be inclined to extend so that the water in the water storage tank 30 can flow smoothly into the filter core body 200, maintaining the humidification state of the filter core body 200.

[0118] It can be understood that when the water in the water storage tank 30 flows under the action of gravity to the humidification filter core 10, the water flow first passes through the split chamber and then enters the filter core body 200. The design of the split chamber can make the water flow more uniformly dispersed, avoiding direct impact of the water flow on a part of the filter core body 200, thereby reducing the local wear of the filter core body 200. In addition, the split chamber can also slow down the water flow speed, ensuring that the water flow can flow more smoothly into the filter core body 200, improving the humidification effect.

[0119] To ensure that the moisture can uniformly penetrate into the filter core body 200, a plurality of shunt holes 116 are arranged on the inner side wall of the first cylinder portion 111. The plurality of shunt holes 116 are distributed circumferentially along the inner side wall of the first cylinder portion 111. By arranging the shunt holes 116, the water in the shunt cavity can penetrate into the filter core body 200 through the shunt holes 116.

[0120] It can be understood that the shunt cavity formed by the partition plate 115 and the first cylinder portion 111 can uniformly hold the water in the water storage tank 30, ensuring uniform distribution of the water flow. The design of the plurality of shunt holes 116 allows the moisture to uniformly penetrate into the filter core body 200, improving the uniformity of humidification.
