Description

TECHNICAL FIELD

[0001] The present application relates to the field of humidifying appliances, in particular to an air humidifying device. BACKGROUND

[0002] Air humidifiers mainly function to increase the humidity of indoor air, and have the effects of improving indoor temperature, protecting furniture and electrical appliances, and promoting human health. Air humidifiers can be divided into mist-type humidifiers and mistless-type humidifiers.

[0003] Traditional mistless-type humidifiers usually include a main machine, a liquid storage cavity, and a humidifying filter element. The liquid storage cavity wets the humidifying filter element. The main machine sucks in air, which is subjected to humidification treatment by the humidifying filter element, and then sends out the humidified air to increase the humidity of indoor air.

[0004] However, in the traditional mistless-type humidifier, there is usually an assembly gap between the humidifying filter element and other components. Air is easy to bypass the humidifying filter element and flow out from the assembly gap, so that the contact area between the air and the humidifying filter element is small, the humidification efficiency is low, and the airflow loss is large. CONTENT OF THE INVENTION

[0005] The embodiments of the present application provide an air humidifying device to increase the contact area between air and a humidifying filter element, so that the air flows to the effective humidification part of the filter element, and the humidification efficiency is improved.

[0006] In a first aspect, the embodiments of the present application provide an air humidifying device, characterized in that it comprises:

[0007] a main machine, comprising:

[0008] a machine shell having a containing cavity and an airflow channel, the airflow channel and the containing cavity being distributed along the axial direction of the machine shell, and the airflow channel being located on the lower side of the containing cavity;

[0009] an airflow driving device arranged in the airflow channel;

[0010] a humidifying filter element, at least part of the structure of the humidifying filter element being arranged in the containing cavity, one end of the humidifying filter element facing the airflow channel having a wind guide surface, in the direction from outside to inside along the radial direction of the machine shell, the distance between the wind guide surface and the airflow channel gradually increases, and an air outlet is arranged on the humidifying filter element.

[0011] When needed, the air flow driving device is started and drives the air to flow in the air flow channel. The air guide surface is designed in a negative angle form so that the contact form of the humidifying filter element and the air flow is designed in a negative angle form. Therefore, when the air passes through the air guide surface of the humidifying filter element, the air will be subjected to gradually increasing space resistance, and the air is forced to flow closer to the surface of the humidifying filter element. The negative angle form also guides the air to avoid the assembly gap, increases the contact area of the air and the humidifying filter element, makes the air flow to the effective humidifying part of the filter element, reduces the air flow loss, and improves the humidifying efficiency of the whole machine.

[0012] In a possible implementation, the humidifying filter element is in clearance fit with the inner wall of the accommodating cavity.

[0013] By using the clearance fit between the humidifying filter element and the inner wall of the accommodating cavity, the humidifying filter element has a certain degree of freedom during assembly, avoiding stress concentration or deformation caused by over-tightening. In addition, during the humidifying process, due to the change of temperature and humidity, the humidifying filter element and the accommodating cavity may be subjected to thermal expansion and contraction. The clearance fit design can allow such small deformation, thereby avoiding the jamming or damage between the components.

[0014] In a possible implementation, the humidifying filter element comprises:

[0015] The shell assembly is arranged in the accommodating cavity along at least part of the axial structure of the machine shell. The shell assembly has a humidifying cavity. The shell assembly has an opening opposite to the air flow channel. The air outlet is arranged on the shell assembly.

[0016] The filter element body is arranged in the humidifying cavity and exposed from the opening. At least part of the surface of the filter element body exposed from the opening constitutes the air guide surface.

[0017] By subdividing the humidifying filter element into the shell assembly and the filter element body, the overall structure is more modularized, and it is more convenient for maintenance and replacement. The user can disassemble and replace the filter element body as needed without replacing the entire humidifying filter element, improving the cleaning convenience and reducing the maintenance and replacement cost.

[0018] In a possible implementation, the air guide surface is a flat surface or an arc surface.

[0019] The flat surface air guide surface is simple in design and easy to manufacture and process. When the air flows through the flat surface, the flow path is relatively direct, which helps to reduce the formation of vortex or turbulence. The arc surface air guide surface also has good air guiding effect, which helps to reduce vortex and turbulence, improve the uniformity and efficiency of air flow, and further increase the contact area of air and the filter element body, thereby improving the humidifying efficiency.

[0020] In a possible implementation, the air flow channel has an air inlet and an air outlet.

[0021] The air inlet is arranged on the outer side wall of the shell, and the air passage is arranged on the bottom wall of the accommodating cavity.

[0022] The air inlet arranged on the outer side wall of the shell facilitates the introduction of air from the external environment. The air passage is arranged on the bottom wall of the accommodating cavity and is in communication with the humidifying filter element, and is adapted to provide an opening for air flowing to the body of the filter element.

[0023] In a possible implementation, the bottom wall of the accommodating cavity is provided with a first grid, and the first grid defines the air passage.

[0024] The first grid serves as the boundary of the air passage, ensuring the orderliness and uniformity of air flow when passing through the filter element or the humidifying cavity. In addition, by arranging and designing the shape of the grid, the air can be guided to flow along a predetermined path, reducing vortex and dead zones, improving humidification efficiency. In addition, as a part of the bottom wall of the accommodating cavity, the first grid can also enhance the overall structural stability of the device and ensure the service life of the device.

[0025] In a possible implementation, the humidifying cavity is annular, and the humidifying cavity is close to the side wall of the accommodating cavity.

[0026] The air outlet is opposite to the humidifying cavity along the axial direction of the shell.

[0027] The humidifying cavity forms an annular space around a certain central axis (such as the central axis of the device). This design fully utilizes the space in the accommodating cavity and optimizes the air flow path, so that the air can pass through the humidifying medium more uniformly, ensuring the humidification efficiency. The air outlet is opposite to the humidifying cavity along the axial direction of the shell. In this way, after the air is humidified in the humidifying cavity, it will be discharged through the air outlet along the axial direction of the shell. This layout reduces air flow resistance, helps to maintain the smoothness of air flow, reduces the generation of vortex and dead zones, and further improves the humidification efficiency.

[0028] In a possible implementation, the shell assembly comprises a first shell and a second shell opposite along the axial direction of the main machine, and the first shell and the second shell are detachably connected, and the first shell and the second shell jointly define the humidifying cavity.

[0029] The detachable connection design between the first shell and the second shell facilitates the disassembly and assembly of the shell assembly, which helps to improve the reliability and service life of the device. In addition, by reasonably designing the shape and structure of the first shell and the second shell and optimizing the shape and position of the humidifying cavity, the humidification efficiency can be improved, the uniformity and smoothness of air humidification can be ensured, and the user experience can be improved.

[0030] In a possible implementation, the first shell comprises:

[0031] The first cylinder part is hollow on the inner side, and is connected with the second shell;

[0032] The first mounting part is arranged at one end of the first cylinder part away from the second shell along the axial direction of the filter core body, and is located on the radial outer side of the first cylinder part. One end of the filter core body is arranged in the first mounting part.

[0033] The design of the first cylinder part and the first mounting part makes the shell assembly have a stable structure, improves the overall stability of the equipment, and in addition, the first shell and the second shell are connected in a detachable manner, so that the shell assembly can be easily disassembled and assembled, facilitating cleaning, maintenance or replacement of the filter core body and the like, and ensuring the user experience.

[0034] In a possible implementation, the first mounting part and the first cylinder part jointly define a first insertion slot that is open toward the second shell along the axial direction of the filter core body, and one end of the filter core body is inserted into the first insertion slot.

[0035] Through the close fit between the filter core body and the first insertion slot, the stability and reliability of the filter core body during humidification can be ensured, and in addition, this design also helps to improve the sealing performance of the humidification cavity, preventing water leakage or air short circuit during humidification.

[0036] In a possible implementation, the second shell comprises:

[0037] The second cylinder part is hollow on the inner side,

[0038] The second mounting part is arranged at one end of the second cylinder part away from the first shell along the axial direction of the filter core body, and is located on the radial outer side of the second cylinder part. The other end of the filter core body is arranged in the second mounting part.

[0039] The design of the second shell makes the installation and disassembly of the filter core body simple and convenient, and the user can easily perform cleaning, replacement of the filter core and the like, prolonging the service life of the equipment, and in addition, by designing the shape and size of the second cylinder part and the second mounting part, the close fit between the filter core body and the second shell can be ensured, air leakage and water overflow are reduced, and the humidification efficiency is ensured.

[0040] In a possible implementation, the second mounting part and the second cylinder part jointly define a second insertion slot that is open toward the first shell along the axial direction of the filter core body, and one end of the filter core body is inserted into the second insertion slot.

[0041] The close fit between the filter core body and the second slot can ensure the stability and reliability of the filter core body during humidification, and the design can also help improve the sealing of the humidification cavity to prevent water leakage or air short circuit during humidification.

[0042] In a possible implementation, the first mounting portion and the side wall of the accommodating cavity are opposite along the axial direction of the shell and are connected,

[0043] The filter core body is in clearance fit with the accommodating cavity,

[0044] The outer diameter of the second mounting portion is smaller than the outer diameter of the filter core body, the filter core body is exposed from the radial outside of the second mounting portion, and forms the air guide surface.

[0045] By reasonably designing the relationship between the first mounting portion, the filter core body, the second mounting portion, and the accommodating cavity, efficient and stable operation of the air humidification device can be ensured, and convenient installation and disassembly experience is provided, and the humidification effect is guaranteed.

[0046] In a possible implementation, part of the structure of the first mounting portion forms a second grid, and the second grid defines an air outlet.

[0047] The second grid as the boundary of the air outlet ensures uniform distribution and effective discharge of air. In addition, by arranging and designing the shape of the grid, the air can be guided to flow along a preset path, reducing vortex and dead zones, improving humidification efficiency. In addition, the second grid can also enhance the overall structural stability of the device and guarantee the service life of the device.

[0048] In a possible implementation, the first shell further comprises:

[0049] A partition plate is arranged on the inner side of the first cylinder portion, and the partition plate and the first cylinder portion together define a top-open split chamber, and the split chamber is used to contain water in the water storage tank.

[0050] A plurality of split holes are arranged on the first cylinder portion in the circumferential direction, and water in the split chamber penetrates into the filter core body through the split holes.

[0051] Through the design of the partition plate, the split chamber, and the split hole, it can be ensured that water can be uniformly and stably supplied to the filter core body, thereby improving the humidification efficiency. The design can ensure that the humidification filter core reaches the preset humidity level, and ensures the use stability of the air humidification device.

[0052] In a possible implementation, the device further comprises:

[0053] A water storage tank is arranged on the upper side of the humidification filter core, and the water storage tank is used to supply water to the split chamber.

[0054] The design of supplying water to the distribution chamber through the water storage tank ensures that the humidifying filter has sufficient water supply during operation, thereby improving humidification efficiency. This design enables the air humidifier to reach the required humidity level in a short time, ensuring a good user experience. In addition, the water storage tank design allows users to easily observe and replenish the water level, thereby reducing operating costs and maintenance difficulties, and improving the user experience.

[0055] The air humidification device provided in this application starts the airflow drive device and drives the air to flow in the airflow channel. The air guide surface is designed so that the contact shape between the humidification filter and the airflow is in the form of a negative angle. When this part of the air passes through the air guide surface of the humidification filter, it will be subject to the gradually increasing spatial resistance, forcing the air to flow closer to the surface of the humidification filter. The negative angle shape will also guide the air to avoid the assembly gap, increase the contact area between the air and the humidification filter, so that the air flows to the effective humidification part of the filter, reduce airflow loss, and improve the overall humidification efficiency of the machine.

It is therefore contemplated that the application covered by the appended claims can include any variations falling within the purview of the application. DETAILED DESCRIPTION

[0067] The exemplary embodiments will be described in detail herein with reference to the accompanying drawings. In the following description, like reference numerals refer to like elements, unless the context clearly dictates otherwise. The following exemplary embodiments are described in the context of the accompanying drawings. These embodiments are not intended to represent all embodiments in accordance with the present application. Rather, they are merely examples of apparatuses and methods in accordance with some aspects of the present application, as detailed in the appended claims.

[0068] Air humidifiers mainly function to increase the humidity of indoor air, and have the effects of improving indoor temperature, protecting furniture and electrical appliances, and promoting human health. From the classification of working principles, air humidifiers can be divided into mist type humidifiers (also known as ultrasonic humidifiers), mistless type humidifiers (also known as cold evaporation humidifiers or pure type humidifiers), and hot evaporation humidifiers. From the classification of use ranges, air humidifiers can also be divided into industrial humidifiers, commercial humidifiers, and household humidifiers, etc.

[0069] Among them, the mist type humidifier usually uses ultrasonic waves to oscillate to atomize water into small particles, and uses a wind moving device to diffuse the water mist into the air to achieve the humidifying effect. This type of humidifier has the advantages of simple structure, high efficiency, and large humidifying capacity. The mistless type humidifier usually simulates the natural evaporation of water, accelerates the evaporation speed of water through a continuous evaporation core, and circulates the air to change the liquid water into gaseous water to achieve the humidifying effect. This type of humidifier has the advantages of low water quality requirement, small humidifying capacity, and is suitable for small space environment, etc.

[0070] Specifically, the conventional mist-free humidifier generally comprises a main body, a liquid storage cavity and a humidifying filter element, the liquid storage cavity wets the humidifying filter element, the main body sucks in air, the air is humidified by the humidifying filter element, and then the humidified air is sent out to increase the humidity in the room.

[0071] However, in the conventional mist-free humidifier, there is usually an assembly gap between the humidifying filter element and other components, air is easy to bypass the humidifying filter element and flow out from the assembly gap, so that the contact area between the air and the humidifying filter element is small, and the humidification efficiency is low.

[0072] In addition, the humidifying filter element of the conventional mist-free humidifier is generally in a vertical cross-section state in the air outlet direction, which also causes the contact area between the humidifying filter element and the initial contact state of the air direction to be small, and has the disadvantage of low humidification efficiency.

[0073] Therefore, the air humidification device provided in the present application is proposed, the airflow driving device is started and drives the air to flow in the airflow channel, and the air deflector makes the contact form between the humidifying filter element and the airflow be designed as a negative angle form, so that the air passing through the air deflector of the humidifying filter element will be subjected to gradually increasing space resistance, forcing the air to flow closer to the surface of the humidifying filter element, the negative angle form also guides the air to avoid the assembly gap, increases the contact area between the air and the humidifying filter element, makes the air flow to the effective humidification part of the filter element, reduces the airflow loss, and improves the humidification efficiency of the whole machine.

[0074] The air humidification device of the embodiment of the present application will be described below. Figures 1-4 The air humidification device of the embodiment of the present application will be described below.

[0075] With reference to Figures 1 to 4 The air humidification device of the embodiment of the present application can be a mist-free air humidification device or a pure type humidification device, and exemplarily, the air humidification device can be a cold evaporation humidifier.

[0076] The air humidification device can comprise a main body 100 and a humidifying filter element 200. The main body 100 comprises a casing 110 and an airflow driving device 120.

[0077] The casing 110 has a containing cavity 111 and an airflow channel 112, the containing cavity 111 is used to install the humidifying filter element 200 and other components, the airflow channel 112 and the containing cavity 111 are distributed along the axial direction of the casing 110, and the airflow channel 112 is located on the lower side of the containing cavity 111, used to guide the air flow, so that the air can be humidified by the humidifying filter element 200, and the airflow is prevented from forming vortex or dead angle in the device.

[0078] The air flow driving device 120 is arranged in the air flow channel 112 and is configured to generate and drive air flow in the air flow channel 112. For example, the air flow driving device 120 can be a fan, a blower or other air driving device. Optionally, the air flow driving device 120 can be designed to operate at low noise to reduce or avoid noise generated during use of the air humidifying device.

[0079] The humidifying filter 200 is a core component in the humidifying process and is configured to absorb moisture and evaporate the moisture into air through air flow. Optionally, the humidifying filter 200 can be made of activated carbon, high efficiency particulate air (HEPA) filter, nanofiber, ceramic, ceramic ball or the like.

[0080] At least part of the structure of the humidifying filter 200 is arranged in the accommodating cavity 111. The humidifying filter 200 has a wind guide surface 200a at one end thereof facing the air flow channel 112. In a radial direction of the machine shell 110 and from outside to inside, the distance between the wind guide surface 200a and the air flow channel 112 gradually increases. The wind guide surface 200a can guide air to flow through the humidifying filter 200 more uniformly and improve the humidifying efficiency. The humidifying filter 200 is provided with an air outlet 200b to discharge humidified air to the environment.

[0081] It can be understood that the wind guide surface 200a realizes a negative angle mode of contact between air flow and the humidifying filter 200. The wind guide surface 200a provides a guiding effect for air. In a radial direction of the machine shell 110 and from outside to inside, the distance between the wind guide surface 200a and the air flow channel 112 gradually increases. When air flows through the wind guide surface 200a, the air is subjected to gradually increasing space resistance, thereby forcing the air to flow closer to the surface of the humidifying filter 200, and thus increasing the contact area between the air and the humidifying filter 200. The negative angle mode of design also causes the air to avoid the assembly gap and thus flow to the humidifying part of the humidifying filter 200, thereby ensuring the humidifying efficiency and reducing wind power loss.

[0082] Optionally, the wind guide surface 200a can be designed as a surface inclined towards the axis, a surface inclined away from the axis, or both a surface inclined towards the axis and a surface inclined away from the axis. The specific design can be made according to the position of the assembly gap.

[0083] For example, when the assembly gap is located on the side of the wind guide surface 200a away from the axis, the wind guide surface 200a can be designed to be inclined towards the axis. When the assembly gap is located between the wind guide surface 200a and the axis, the wind guide surface 200a can be designed to be inclined away from the axis. When the assembly gap is located on the side of the wind guide surface 200a away from the axis and between the wind guide surface 200a and the axis, the wind guide surface 200a can be designed to include a folded surface or a curved surface inclined towards the axis and a folded surface or a curved surface inclined away from the axis.

[0084] In some examples, for some soft material compositions of the humidifying filter 200, such as fiber cotton, sponge, activated carbon (which can exist in the form of particles or powder and be embedded in soft materials), special fibers (such as nanofiber, antibacterial and mildew-resistant fiber, etc.), etc., can have high elasticity and high resilience. It can be understood that when air is blown to the air guide surface 200a, the air guide surface 200a can produce a certain deformation. In this way, when air is blown to the air guide surface 200a, the inclined surface design of the air guide surface 200a will guide the air flow and produce slight deformation, thereby making the humidifying filter 200 tightly fit the assembly gap, making the assembly gap sealed, avoiding air entering the assembly gap, and thereby ensuring the humidifying efficiency.

[0085] In this way, the air humidifying device provided by the present application can drive the air to flow in the air flow channel 112 when it needs to be used, and the contact form of the humidifying filter 200 and the air flow is designed in the form of a negative angle by the air guide surface 200a. Therefore, when the part of the air passes through the air guide surface 200a of the humidifying filter 200, it will be subjected to gradually increasing space resistance, forcing the air to flow closer to the surface of the humidifying filter 200. The negative angle form will also guide the air to avoid the assembly gap, increase the contact area between the air and the humidifying filter 200, make the air flow to the effective humidifying part of the filter, and improve the humidifying efficiency of the whole machine.

[0086] In addition, the axial distribution of the air flow channel 112 and the containing cavity 111, and the special design of the air guide surface 200a, together optimize the air flow path, so that the air can smoothly flow through the humidifying filter 200, reducing the possibility of air bypassing the filter and flowing out directly.

[0087] In some embodiments, in combination Figure 2 The humidifying filter 200 is gap-fitted with the inner wall of the containing cavity 111.

[0088] It can be understood that gap fitting refers to that when two parts are assembled, there is a certain gap between the fitting surfaces of the two parts. This fitting method allows the parts to have a certain relative movement or deformation after assembly, so as to adapt to different working conditions and assembly requirements.

[0089] By gap-fitting the humidifying filter 200 and the inner wall of the containing cavity 111, the humidifying filter 200 has a certain degree of freedom during assembly, avoiding stress concentration or deformation caused by over-tightening. In addition, during the humidifying process, due to the change of temperature and humidity, the humidifying filter 200 and the containing cavity 111 can expand and contract with heat. The gap-fitting design can allow such small deformation, thereby avoiding the jamming or damage between the parts.

[0090] It should be noted that the size of the gap should be determined according to the material, size, working condition and required sealing performance of the humidifying filter element 200. A too large gap may result in a decrease in sealing performance, while a too small gap may increase assembly difficulty and stress concentration.

[0091] Optionally, a sealing member such as a sealing ring, sealing glue or the like can be designed between the humidifying filter element 200 and the fitting surface of the accommodating cavity 111.

[0092] In addition, the humidifying filter element 200 is gap-fitted with the inner wall of the accommodating cavity 111, that is, the assembly gap is located on the side of the humidifying filter element 200 away from the axis. Correspondingly, in some embodiments, in combination with Figure 1 and Figure 2 , the air guide surface 200a can be designed to be inclined towards the axis, so that when the air flows to the air guide surface 200a, the air will be close to the air guide surface 200a and move along the axis under the guidance of the air guide surface 200a, greatly reducing the influence of the assembly gap on the air flow direction and ensuring the humidifying efficiency.

[0093] In some embodiments, in combination with Figure 1 , Figure 2 and Figure 3 , the humidifying filter element 200 comprises a shell assembly 210 and a filter element body 220. The shell assembly 210 constitutes the main frame of the humidifying filter element 200, and the filter element body 220 is the core part of the humidifying filter element 200, responsible for absorbing and evaporating water to increase the humidity of the air.

[0094] Among them, at least part of the structure of the shell assembly 210 along the axis of the cabinet 110 is arranged in the accommodating cavity 111, the shell assembly 210 has a humidifying cavity 210a for accommodating and supporting the filter element body 220 and serving as the main place for water evaporation, and the shell assembly 210 has an opening opposite to the air flow channel 112, which allows air to enter the humidifying cavity 210a and contact the filter element body 220. The air outlet 200b is arranged on the shell assembly 210 for discharging the humidified air from the device.

[0095] The filter element body 220 is arranged in the humidifying cavity 210a and exposed from the opening, and at least part of the surface of the filter element body 220 exposed from the opening constitutes the air guide surface 200a. The air guide surface 200a plays a guiding role when the air flows through the humidifying filter element 200, guiding the air to flow more evenly through the filter element body 220, ensuring that the air is in sufficient contact with the filter element body 220, increasing the contact area between the air and the water, and improving the humidifying efficiency.

[0096] By subdividing the humidifying filter element 200 into the shell assembly 210 and the filter element body 220, the overall structure is more modular, more convenient to maintain and replace, and the user can disassemble and replace the filter element body 220 as needed without replacing the entire humidifying filter element 200, improving cleaning convenience and reducing maintenance and replacement costs.

[0097] Optionally, the connection between the shell assembly 210 and the filter element body 220 can be a clamping connection, a flange connection, a fixing piece connection, a plug-in connection, or a sliding rail connection, and the specific connection mode can be selected according to actual needs, which is not limited here.

[0098] In some embodiments, in combination with Figure 4 The air guide surface 200a is a flat surface or an arc surface.

[0099] The flat surface air guide surface 200a is simple in design, easy to manufacture and process, and when air flows through the flat surface, the flow path is relatively direct, which helps to reduce the formation of vortex or turbulent flow. Optionally, the flat surface air guide surface 200a can be suitable for small household humidifying devices, portable humidifying devices, etc.

[0100] The arc surface air guide surface 200a also has good air guiding effect, which helps to reduce vortex and turbulent flow, improve the uniformity and efficiency of air flow, and in addition, the arc surface design can further increase the contact area between air and the filter element body 220, thereby improving the humidifying efficiency. Optionally, the arc surface air guide surface 200a can be suitable for industrial humidifying devices.

[0101] Optionally, the air guide surface 200a can also be a wave-shaped air guide surface 200a, a conical or funnel-shaped air guide surface 200a, etc., as long as the functional guiding effect of the air guide surface 200a is achieved, which is within the protection scope of the present application, which is not limited here.

[0102] In addition, it should be noted that the shape of the air guide surface 200a can also be considered comprehensively according to the specific needs of the device, the humidifying efficiency, the air flow uniformity, the manufacturing cost, and the appearance of the device, etc., which is not limited here.

[0103] In some embodiments, in combination with Figure 1 、 Figure 2 and Figure 3 The air flow channel 112 has an air inlet 1121 and an air passage 1122, the air inlet 1121 is arranged on the outer side wall of the cabinet 110, and the air passage 1122 is arranged on the bottom wall of the accommodating cavity 111.

[0104] The air inlet 1121 arranged on the outer side wall of the shell 110 facilitates the introduction of air from the external environment. Optionally, the air inlet 1121 can be arranged at the upper end, lower end or central position of the outer side wall. Optionally, the shape of the air inlet 1121 can be annular, such as being distributed circumferentially around the axis of the air humidifying device. It should be noted that the shape, size and position of the air inlet 1121 can be adjusted according to the humidifying capacity of the device and the air flow demand, which is not limited herein.

[0105] Optionally, a filter can also be designed at the air inlet 1121 to block dust and impurities in the air from entering the interior of the device. Optionally, the filter can be designed to be detachable for easy disassembly, cleaning or replacement.

[0106] Optionally, the air inlet 1121 can be designed as a grille. Optionally, the grille can also be designed with an inclined surface to limit the air inlet direction.

[0107] The air outlet 1122 is arranged on the bottom wall of the accommodating cavity 111 and communicates with the humidifying filter element 200, and is adapted to provide an opening for air flowing to the filter element body 220. Optionally, the air flow channel 112 can be provided with a guide member which can be inclined from the air inlet 1121 towards the air outlet 1122 to guide the air flowing to the air outlet 1122.

[0108] In addition, the position of the air outlet 1122 needs to match the arrangement of the filter element body 220. For example, in combination with Figure 1 and Figure 2 , the filter element body 220 can be designed as an axially arranged annular column structure, and the air guide surface 200a is arranged on the end of the filter element body 220 and is axially annularly distributed. Correspondingly, the air outlet 1122 can be designed as an annularly distributed opening and is opposite to the filter element body 220 to ensure that the air flowing out of the air outlet 1122 can uniformly flow through the filter element body 220 to avoid the situation of local over-humidification or insufficient humidification.

[0109] For example, the air outlet 1122 can be designed in a diffuser shape or a converging shape to achieve smooth transition and uniform distribution of air flow.

[0110] In some embodiments, in combination with Figure 2 , the bottom wall of the accommodating cavity 111 is provided with a first grille 113, and the first grille 113 defines the air outlet 1122.

[0111] Optionally, the shape of the grille bars of the first grille 113 can be designed according to the humidifying capacity of the device and the air flow demand. For example, the first grille 113 can be designed as a rectangle, a circle or an ellipse, etc. to achieve uniform distribution of air.

[0112] Optionally, the grille bars of the first grille 113 can also be designed with an inclined surface to guide the air direction.

[0113] Optionally, the spacing between the grid bars can be designed according to the humidification capacity or air flow requirement of the device to ensure the stability of the air flow. It should be noted that too large spacing may result in uneven air flow, while too small spacing may increase the resistance of air flow.

[0114] It can be seen that the first grid 113, as the boundary of the air passage 1122, ensures the orderliness and uniformity of the air flow when passing through the filter core or the humidification cavity 210a. In addition, through the arrangement and shape design of the grid, the air can be guided to flow along the preset path, reducing vortex and dead zones, and improving the humidification efficiency. In addition, the first grid 113, as a part of the bottom wall of the containing cavity 111, can also enhance the overall structural stability of the device and ensure the service life of the device.

[0115] In some embodiments, in combination with Figure 1 , Figure 2 and Figure 3 , the humidification cavity 210a is annular, and the humidification cavity 210a is close to the side wall of the containing cavity 111. Thus, the humidification cavity 210a forms an annular space around a certain central axis (such as the central axis of the device), which fully utilizes the space in the containing cavity 111 and optimizes the air flow path, so that the air can pass through the humidification medium more uniformly, ensuring the humidification efficiency.

[0116] The air outlet 200b is opposite to the humidification cavity 210a along the axial direction of the shell 110. Thus, after being humidified in the humidification cavity 210a, the air is discharged through the air outlet 200b along the axial direction of the shell 110. This layout reduces the air flow resistance, helps to maintain the smoothness of the air flow, reduces the generation of vortex and dead zones, and thus improves the humidification efficiency.

[0117] Optionally, the position of the air outlet 200b can be arranged above or below the humidification cavity 210a. The specific position can be selected according to the actual design requirements of the device to ensure that the humidified air can be directly and efficiently discharged to the target area.

[0118] Optionally, in combination with Figure 2 , the position of the air outlet 200b can be arranged above the humidification cavity 210a, and the air inlet 1121 can be arranged at a lower position of the side wall of the air humidification device. Thus, during actual operation, the airflow driving device 120 drives the air to enter the air humidification device from the lower end through the air inlet 1121, and the air flows out from the top of the air humidification device through the air outlet 200b after passing through the humidification filter 200, ensuring the smoothness and stability of the air flow.

[0119] In some embodiments, in combination with Figure 2 and Figure 3The shell assembly 210 comprises a first shell 211 and a second shell 212 which are axially opposite to each other and detachably connected, and together define a humidifying cavity 210a.

[0120] As such, it can be understood that the first shell 211 and the second shell 212 are respectively located at two sides of the main machine 100 and arranged in opposite directions along the axial direction of the main machine 100. The detachable connection between the first shell 211 and the second shell 212 allows the user to easily disassemble and assemble the shell assembly 210 for cleaning, maintenance, or replacement of the filter core body 220, etc. When the first shell 211 and the second shell 212 are connected together, they together define a ring-shaped humidifying cavity 210a for accommodating the filter core body 220 to ensure that the air contacts the filter core body 220 and is humidified.

[0121] For example, the detachable connection between the first shell 211 and the second shell 212 can be a threaded connection, a snap connection, a sliding rail connection, etc.

[0122] It can be seen that the detachable connection between the first shell 211 and the second shell 212 facilitates the disassembly and assembly of the shell assembly 210, which helps to improve the reliability and service life of the device. In addition, by reasonably designing the shape and structure of the first shell 211 and the second shell 212 and optimizing the shape and position of the humidifying cavity 210a, the humidifying efficiency can be improved, the uniformity and smoothness of air humidification can be ensured, and the user's experience can be improved.

[0123] In some embodiments, in combination with Figure 2 and Figure 3 The first shell 211 comprises a first cylinder portion 2111 and a first mounting portion 2112.

[0124] The first cylinder portion 2111 is hollow on the inside to form part of the humidifying cavity 210a. This hollow area together with the second shell 212 defines a complete humidifying cavity 210a for air to contact the humidifying medium and be humidified. The first cylinder portion 2111 is connected to the second shell 212, and the connection mode can be a snap connection, a sliding connection, etc.

[0125] The first mounting portion 2112 is arranged at one end of the first cylinder portion 2111 away from the second shell 212 along the axial direction of the filter core body 220 (also the axial direction of the shell 110), and is located on the radial outer side of the first cylinder portion 2111. One end of the filter core body 220 is arranged in the first mounting portion 2112.

[0126] It can be understood that the first mounting portion 2112 is suitable for providing a stable mounting platform for the first cylinder portion 2111, and is used for mounting one end of the filter core body 220 to realize the mounting and limiting of the filter core body 220. Optionally, the first mounting portion 2112 and the filter core body 220 can be in clamping cooperation. For example, the first mounting portion 2112 can be provided with a limiting clamping groove, and the filter core body 220 can be embedded in the limiting clamping groove to ensure the stability and reliability of the filter core body 220 during humidification.

[0127] It can be seen that the design of the first cylinder portion 2111 and the first mounting portion 2112 makes the shell assembly 210 have a stable structure, improves the overall stability of the equipment, and in addition, the first shell 211 and the second shell 212 are connected in a detachable manner, so that the shell assembly 210 can be easily disassembled and assembled, facilitating cleaning, maintenance or replacement of the filter core body 220 and the like, and ensuring the user's experience.

[0128] In some embodiments, in combination Figure 2 The first mounting portion 2112 and the first cylinder portion 2111 together define a first insertion slot 2113 that is open in the axial direction of the filter core body 220 towards the second shell 212, and one end of the filter core body 220 is inserted into the first insertion slot 2113.

[0129] Optionally, the shape and size of the first insertion slot 2113 are adapted to the filter core body 220 to ensure that the filter core body 220 can be tightly and stably inserted therein. When the filter core body 220 is inserted, its surface will be in close contact with the inner wall of the first insertion slot 2113, thereby forming a stable connection.

[0130] Through the close cooperation between the filter core body 220 and the first insertion slot 2113, the stability and reliability of the filter core body 220 during humidification can be ensured, and in addition, this design also helps to improve the sealing of the humidification cavity 210a to prevent water leakage or air short circuit during humidification.

[0131] It can be seen that the design of the first insertion slot 2113 improves the convenience of mounting and dismounting the filter core body 220. In actual operation, only one end of the filter core body 220 needs to be aligned with the opening of the first insertion slot 2113, and then inserted along the axial direction. Correspondingly, when dismounting, the filter core body 220 only needs to be pulled out of the first insertion slot 2113, thereby facilitating cleaning, maintenance or replacement of the filter core and the like, which helps to improve the reliability and service life of the equipment and improve the user's experience.

[0132] In some embodiments, in combination Figure 2The second shell 212 comprises a second cylinder portion 2121 and a second mounting portion 2122.

[0133] The second cylinder portion 2121 is hollow on the inside, which can provide installation space for other components of the air humidifying device, such as a water storage portion. In addition, it can be understood that the second cylinder portion 2121 is designed in a cylindrical shape, which, together with the first cylinder portion 2111, supports the inside of the filter core body 220, thereby ensuring the installation stability of the filter core body 220.

[0134] The second mounting portion 2122 is arranged at one end of the second cylinder portion 2121 away from the first shell 211 along the axial direction of the filter core body 220 and is located on the radial outside of the second cylinder portion 2121. The other end of the filter core body 220 is arranged in the second mounting portion 2122.

[0135] The second mounting portion 2122 is used to fix the other end of the filter core body 220, thereby ensuring the stability and reliability of the filter core body 220 in the second shell 212. Optionally, the mounting manner between the second mounting portion 2122 and the filter core body 220 can be clamping, sliding connection, etc. Optionally, the second mounting portion 2122 can also be designed with a guide groove to provide guidance for the installation of the filter core body 220.

[0136] The design of the second shell 212 makes the installation and disassembly of the filter core body 220 simple and convenient, so that the user can easily perform cleaning, filter replacement, etc., thereby prolonging the service life of the device. In addition, by designing the shape and size of the second cylinder portion 2121 and the second mounting portion 2122, the close fit between the filter core body 220 and the second shell 212 can be ensured, air leakage and water overflow can be reduced, and the humidification efficiency can be ensured.

[0137] In some embodiments, in combination with Figure 2 The second mounting portion 2122 and the second cylinder portion 2121 together define a second insertion slot 2123 that is open toward the first shell 211 along the axial direction of the filter core body 220. One end of the filter core body 220 is arranged in the second insertion slot 2123.

[0138] Optionally, the second insertion slot 2123 can be adapted to the end of the filter core body 220, so as to ensure that the filter core body 220 can be tightly and stably inserted therein. When the filter core body 220 is inserted, the surface thereof will be in close contact with the inner wall of the second insertion slot 2123, thereby forming a stable connection.

[0139] Through the close fit between the filter core body 220 and the second insertion slot 2123, the stability and reliability of the filter core body 220 during the humidification process can be ensured. This design also helps to improve the sealing performance of the humidification cavity 210a, thereby preventing water leakage or air short circuit during the humidification process.

[0140] It can be seen that the design of the second slot 2123 improves the convenience of installing and dismounting the filter core body 220. In actual operation, only one end of the filter core body 220 needs to be aligned with the opening of the second slot 2123 and then inserted along the axial direction. Correspondingly, when dismounting, the filter core body 220 only needs to be pulled out of the second slot 2123, thereby facilitating cleaning, maintenance or replacement of the filter core and the like, which helps to improve the reliability and service life of the equipment and improve the user experience.

[0141] In some examples, in combination with Figure 2 and Figure 4 Since one end of the filter core body 220 is provided with the air guide surface 200a, and the host 100 is also designed with the air passage 1122 in cooperation with the air guide surface 200a, it can be understood that in order to provide an air flow channel for the air guide surface 200a and the air passage 1122, one end of the filter core body 220 inserted into the second slot 2123 can be smaller than the outer diameter of the filter core body 220, so as to provide a flow space for the air flowing through the air passage 1122 and the air guide surface 200a, and ensure the smoothness of air flow.

[0142] In some embodiments, in combination with Figure 2 , the first mounting portion 2112 is opposite to the side wall of the accommodating cavity 111 along the axial direction of the shell 110 and is connected. Optionally, the mounting manner between the first mounting portion 2112 and the shell 110 can be clamping, sliding fit connection or the like. In this way, when it is necessary to install the humidification filter core 200 on the host 100, the connection and fixation between the first mounting portion 2112 and the shell 110 can be realized by opposing and applying force. Optionally, a sealing element can also be designed at the connection to ensure the sealing property of the connection.

[0143] The filter core body 220 is gap-fitted with the accommodating cavity 111. Such gap fitting allows the filter core body 220 to have a certain activity space in the accommodating cavity 111, and also prevents the filter core body 220 from being rubbed or stressed with the accommodating cavity 111 due to possible expansion or contraction during humidification.

[0144] The outer diameter of the second mounting portion 2122 is smaller than the outer diameter of the filter core body 220, and the filter core body 220 is exposed from the radial outer side of the second mounting portion 2122 and forms the air guide surface 200a. In this way, it can be understood that when the filter core body 220 is inserted into the second slot 2123, part of the outer surface of the filter core body 220 will be exposed from the radial outer side of the second mounting portion 2122, and the exposed outer surface of the filter core body 220 forms an air guide surface 200a. The air guide surface 200a can guide the direction of air flow, so that the air can be more uniformly humidified through the filter core body 220. In addition, the air guide surface 200a also helps to reduce the turbulence and vortex of air flow, thereby improving the humidification efficiency.

[0145] It can be seen that, by reasonably designing the relationship between the first mounting portion 2112, the filter element body 220, the second mounting portion 2122, and the accommodating cavity 111, the efficient and stable operation of the air humidifying device can be ensured, and convenient installation and disassembly experience is provided, and the humidifying effect is guaranteed.

[0146] In some embodiments, in combination with Figure 2 and Figure 3 , part of the structure of the first mounting portion 2112 forms a second grid 2114, and the second grid 2114 defines the air outlet 200b.

[0147] Optionally, the shape of the grid bars of the second grid 2114 can be designed according to the humidifying capacity and air flow demand of the device. For example, the second grid 2114 can be designed as a rectangle, a circle, or an ellipse, etc., to achieve uniform distribution of air.

[0148] Optionally, the grid bars of the second grid 2114 can also be designed with inclined surfaces, which are suitable for guiding the air direction.

[0149] Optionally, the spacing between the grid bars can be designed according to the humidifying capacity or air flow demand of the device to ensure the stability of air flow. It should be noted that too large spacing can cause uneven air flow, and too small spacing can increase air flow resistance.

[0150] It can be seen that, as the boundary of the air outlet 200b, the second grid 2114 ensures the uniform distribution and effective discharge of air. In addition, by arranging and designing the shape of the grid, the air can also be guided to flow along the preset path, reducing vortex and dead zones, improving the humidifying efficiency. In addition, the second grid 2114 can also enhance the overall structural stability of the device, and guarantee the service life of the device.

[0151] In some embodiments, in combination with Figure 2 , the first shell 211 further includes a partition plate 2115 arranged on the inner side of the first cylindrical portion 2111, and the partition plate 2115 and the first cylindrical portion 2111 together define a top-opened shunt cavity 2116 for containing water in the water storage tank 300. By designing the partition plate 2115, the required amount of water stored in the shunt cavity 2116 is ensured, and the structural stability and reliability are maintained. In addition, the top of the shunt cavity 2116 is open, allowing water to flow from the water storage tank 300 and fill the shunt cavity 2116.

[0152] The first cylinder part 2111 is provided with a plurality of shunt holes 2117 distributed along the circumferential direction of the first cylinder part 2111. The water in the shunt cavity 2116 seeps into the filter core body 220 through the shunt holes 2117. The circumferential distribution design of the shunt holes 2117 ensures that the water seeps out of the shunt cavity 2116 uniformly, avoiding the situation of local over-wetting or dryness.

[0153] Optionally, the number and size of the shunt holes 2117 can be designed according to different humidification requirements to further adjust the seepage speed and amount of water.

[0154] Through the design of the partition plate 2115, the shunt cavity 2116 and the shunt holes 2117, it can be ensured that the water can be uniformly and stably supplied to the filter core body 220, thereby improving the humidification efficiency. The design can ensure that the humidification filter core 200 reaches the preset humidity level, and ensures the use stability of the air humidification equipment.

[0155] Optionally, the partition plate 2115 can be designed to be inclined downward along the radial direction of the center axis, suitable for forming a downward air guide surface 200a, providing potential energy for water, accelerating water flow, and also avoiding the residue of excess water flow in the shunt cavity 2116.

[0156] In some embodiments, in combination with Figure 1 and Figure 2 , the air humidification equipment further comprises a water storage tank 300 arranged on the upper side of the humidification filter core 200, and the water storage tank 300 is used to supply water to the shunt cavity 2116.

[0157] Optionally, the water in the water storage tank 300 can flow into the shunt cavity 2116 through a preset mode, such as gravity, pumping, etc. For example, by arranging the water storage tank 300 on the upper side of the humidification filter core 200, the water can be naturally flowed into the shunt cavity 2116 by gravity. This design is simple and convenient, and reduces the operation cost and maintenance difficulty of the equipment.

[0158] Optionally, a sealing member such as a sealing gasket, a sealing ring, etc. can be designed between the water storage tank 300 and the shunt cavity 2116 to ensure the sealing performance of the connection between the two.

[0159] Through the design of the water storage tank 300 supplying water to the shunt cavity 2116, it can be ensured that the humidification filter core 200 has sufficient water supply during operation, thereby improving the humidification efficiency. The design makes the air humidification equipment can reach the required humidity level in a short time, ensuring the use experience. In addition, the design of the water storage tank 300 also makes the user can conveniently observe and supplement the water amount, thereby reducing the use cost and maintenance difficulty, and improving the use experience of the user.

[0160] Optionally, in some embodiments, in combination with Figure 2, a blocking assembly 400 can be designed between the shunt hole 2117 and the shunt cavity 2116. Its main function is to control the water flow channel between the shunt hole 2117 and the shunt cavity 2116, that is, when the blocking assembly 400 is in a blocking state, it can prevent water flow from the shunt hole 2117 into the shunt cavity 2116; and when the blocking assembly 400 is opened, it allows water to flow smoothly. This design can achieve communication and blocking through the opening or closing of the device, and also achieve the stage of the humidifying filter element 200 during use.

[0161] Optionally, the design of the blocking assembly 400 can be various, including but not limited to valves, plugs, knobs, etc.

[0162] Optionally, the operation mode of the blocking assembly 400 can be manual or automatic. Exemplarily, manual operation can include rotating, pushing, pulling or pressing, etc. Automatic operation can rely on sensors, motors and other auxiliary equipment or structural design. The specific selection can be made according to actual needs, which is not limited here.

[0163] It should be noted that any implementation of the blocking assembly 400 can be within the scope of the present application, which is not limited here.

[0164] By introducing the blocking assembly 400, the running state of the humidifying device can be more flexibly controlled, and timely water replenishment can be achieved. In addition, the design of the blocking assembly 400 makes the maintenance of the device more convenient. When cleaning or replacing the filter element is needed, the blocking assembly 400 can be closed to cut off the water flow, thereby avoiding the risk of water splashing or leakage.

[0165] Finally, it should be noted that: other embodiments of the present application will be easily thought of by those skilled in the art after considering the specification and practicing the application disclosed herein. The present application is intended to cover any variations, uses or adaptive changes of the present application, which follow the general principles of the present application and include common knowledge or conventional technical means in the art which are not disclosed by the present application, and are not limited to the precise structure described above and shown in the drawings, and various modifications and changes can be made without departing from the scope thereof. The scope of the present application is only limited by the appended claims.
