Description

Technical Field

[0001] The present application relates to the technical field of air purification, and in particular to an air purifier. Background Art

[0002] Air purifier, also known as air cleaner, air freshener, or purifier, is a product that can absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odor, bacteria, allergens, decoration pollution such as formaldehyde, etc.), effectively improving air cleanliness. It is mainly divided into household, commercial, industrial, and building types.

[0003] Air purifiers include filters, such as High-Efficiency Particulate Air (HEPA), which need to be cleaned or replaced regularly. However, in current air purifier products, it is difficult to remove the filters, and users have a poor experience in disassembly. Specifically, the shapes of HEPA vary, including integrated and split-half types. For the split-half HEPA, both HEPAs need to be fixed to the main body of the air purifier through a snap-on structure. In this way, both hands are required for disassembly, that is, the HEPA is disassembled by pressing the snaps on both sides of the fuselage. In this way, both hands are occupied, which is more inconvenient. Utility Model Content

[0036] To make the technical solutions and beneficial effects of this application more clearly understood, the following detailed description is given by way of specific embodiments. The accompanying drawings are not necessarily drawn to scale, and local features may be enlarged or reduced to more clearly illustrate the details of the local features. Unless otherwise defined, the technical and scientific terms used herein have the same meanings as those in the technical field to which this application belongs.

[0037] The present application provides an air purifier, referring to Figure 1-Figure 3 , air purifier includes:

[0038] The body 10 has an air duct 11 extending along a first direction. The air duct 11 has air duct openings in the circumferential and axial directions of the body 10, one of which is an air inlet 111 and the other is an air outlet 112. The axial direction of the air duct 11 is parallel to the first direction, and the circumferential direction surrounds the first direction.

[0039] The air filter element includes a first air filter element 21 and a second air filter element 22. The first air filter element 21 and the second air filter element 22 are arranged around the outer periphery of the fuselage 10 to surround the circumferential air duct opening of the air duct 11, so that air flows into and out of the air duct 11 from the circumferential direction and passes through the air filter element.

[0040] The first mounting post 30 is mounted on a circumferential side of the fuselage 10 and is circumferentially located between the first air filter 21 and the second air filter 22. The first mounting post 30 includes a movable first fastener 31. The first and second air filters 21 and 22 are each provided with a second fastener 211 at their first ends. The first fastener 31 and the second fastener 211 engage with each other to establish a connection with the first mounting post 30.

[0041] The second mounting post 50 is mounted on the circumferential side of the fuselage 10 and is spaced apart from the first mounting post 30 in the circumferential direction of the fuselage; the second ends of the first air filter 21 and the second air filter 22 are connected to the second mounting post 50 via a mortise and tenon structure;

[0042] The first latching member 31 is further provided with a pressing portion 311 . By applying force to the pressing portion 311 , the first latching member 31 is driven to move, thereby releasing the engagement between the first latching member 31 and the second latching member 211 .

[0043] Specifically, the first direction can be a vertical direction, marked as D1 in the figure. The first mounting post extends along the first direction, and the two air filters are engaged with the first mounting post in a second direction, which can be a horizontal direction. The above directions are based on the normal operation of the air purifier.

[0044] In actual use, it is more technically reasonable for the gas to move up and down. It can be understood that in different specific environments, the first direction can also be other directions.

[0045] Specifically, the fuselage 10 may be cylindrical in shape, and the air duct 11 may be a cylindrical inner hole. In this way, the area of ​​the air duct opening in the circumferential direction of the fuselage 10 is larger, and the flow of gas in the air duct 11 is smoother.

[0046] In this embodiment, reference Figure 4 The circumferential air duct openings can be air inlets 111, and the axial air duct openings can be air outlets 112. Axial air duct openings are only provided at the top. That is, airflow enters from the circumference and exits from the top, which better conforms to gas flow patterns. The airflow directions are shown in the arrows in the figure, marked D2 and D3, respectively.

[0047] Specifically, the air filter element can be Hepa. More specifically, the first air filter element 21 and the second air filter element 22 can be identical, so that they are easy to process and install. It is understood that in some cases, the first air filter element 21 and the second air filter element 22 can be different.

[0048] In addition, it can be understood that the air filter element may not only be the first air filter element 21 and the second air filter element 22, but may be more air filters; the structure of multiple air filters connected to the fuselage 10 is the same as the first air filter element 21 or the second air filter element 22.

[0049] It is understandable that the first latch 31 can move in a direction different from the latching direction to achieve the purpose of releasing the latch. For example, if the latching direction is horizontal, the movement direction of the first latch 31 can be vertical.

[0050] The force applied to the pressing portion 311 may be a force in the same direction as the movement direction of the first latch 31. It is understood that in other cases, forces in other directions may be applied, but a force component in the same direction as the movement direction of the first latch 31 may be generated through a certain structure.

[0051] The mortise and tenon structure of the second mounting post 50 secures both ends of the air filter, ensuring a more stable installation. Furthermore, the mortise and tenon structure only positions the two connected components, not clamps them, making installation and removal of the air filter easier. Specifically, the second end of the air filter is first positioned using the mortise and tenon structure, and then the snap-fit ​​structure at the first end is used to position and clamp it. For removal, the reverse process occurs: the snap-fit ​​structure at the first end is first released, allowing the mortise and tenon structure at the second end to naturally release under the action of gravity.

[0052] Specifically, the mortise (not shown in the figure) in the mortise and tenon structure can be a rectangular groove, and the tenon 212 can be a rectangular protrusion. In this way, compared with the use of structures such as dovetail tenon, the tenon 212 can be inserted into the mortise along the connection direction without having to be connected in other directions, which is convenient for installation.

[0053] The air purifier of the embodiment of the present application is provided with a first mounting column 30 installed on the side of the body 10, and the first mounting column 30 includes a movable first fastener 31; the air filter is provided with a second fastener 211, which is connected to the first mounting column 30 by snapping; the first fastener 31 is provided with a pressing portion 311, and by applying force to the pressing portion 311, the connection between the first fastener 31 and the second fastener 211 can be released, and the air filters on the left and right sides can be released at the same time; in this way, the removal of the air filter is convenient and quick.

[0054] In other embodiments of the present application, reference is made to Figure 3 The first mounting column 30 further includes a reset elastic member 32 , which is located at one end of the movement trajectory of the first latch member 31 . When force is applied to the pressing portion 311 , the reset elastic member 32 is compressed and stores energy.

[0055] Thus, during the process of engaging the first and second latches 31 and 211, the state of the reset elastic member 32 changes as follows: the second latch 211 moves in the direction of contact with the first latch 31, and after contacting the first latch 31, a driving force is generated to drive the first latch 31 to move. The reset elastic member 32 is compressed and stores energy. After the second latch 211 moves to a preset position, the reset elastic member 32 is reset, and the first latch 31 locks the second latch 211 to complete the engagement. During disassembly, force is applied to the pressing portion 311, the reset elastic member 32 is compressed, the first latch 31 releases the second latch 211, and the second latch 211 is disconnected from the first latch 31 under the action of external force or gravity.

[0056] Moving to the preset position refers to moving to the position where the clamping is completed. After the clamping is completed, the second clamping member 211 stops generating the driving force for driving the first clamping member 31 to move, so that the reset elastic member 32 is reset.

[0057] The compression or extension direction of the resetting elastic member 32 is the same as the movement direction of the first locking member 31 .

[0058] Specifically, the resetting elastic member 32 may be a compression spring, the elastic force of which can be controlled by parameters such as wire diameter and pitch, making the elastic force more controllable and the cost lower.

[0059] In other embodiments of the present application, reference is made to Figure 3 The first mounting column 30 is provided with a mounting groove 33 for accommodating the first fastener 31, and the first fastener 31 can move in the mounting groove 33; the side wall of the mounting groove 33 is provided with a first through hole 331, so that the second fastener 211 passes through the first through hole 331 and is engaged with the first fastener 31.

[0060] In this way, the movement of the first latch 31 is more stable.

[0061] In some other embodiments of the present application, the first fastening member 31 includes a fastening slot 312 , and the second fastening member 211 includes a hook 2111 that cooperates with the fastening slot 312 .

[0062] That is, the hook 2111 hooks the slot 312 to complete the snap connection. The shape of the hook 2111 is shown in the accompanying drawings. The front end of the hook 2111 is provided with an arc surface or an inclined surface, which is conducive to entering the slot 312.

[0063] In other embodiments of the present application, reference is made to Figure 5-Figure 7 The first latch 31 is provided with a guide slope 313 on the outside of the slot 312 toward the second latch 211, so that when the second latch 211 contacts the first latch 31, a component force is generated to push the first latch 31 to expose the slot 312 through movement.

[0064] It is understood that the direction of the component force generated by the guide inclined surface 313 is perpendicular to the movement direction of the second latch 211. For example, if the second latch 211 moves horizontally, the direction of the component force is vertical. The magnitude of the component force is related to the inclination angle of the inclined surface.

[0065] The guiding inclined surface 313 can cooperate with the arc surface or inclined surface at the front end of the hook 2111 described above, so that the contact area is larger and the force is more stable.

[0066] In some other embodiments of the present application, the number of the second fasteners 211 is two, and the side wall of the installation slot 33 is defined with two first through holes 331 .

[0067] In this way, disassembly is more convenient and the buckle connection is more secure.

[0068] In other embodiments of the present application, reference is made to Figure 3 The body 10 further includes a cover plate 40 , which covers the first mounting post 30 and seals the first fastener 31 in the mounting groove 33 ; a guide groove for the first fastener 31 to move is formed on the inner wall of the cover plate 40 .

[0069] The first latching member 31 and the resetting elastic member 32 can be enclosed in the mounting groove 33 by the cover plate 40. The movement of the first latching member 31 is more stable and reliable.

[0070] In other embodiments of the present application, the cover plate 40 is provided with a second through hole 41 that exposes the pressing portion 311 and allows the pressing portion 311 to move, so that the user can apply force to the pressing portion 311 from the outside of the cover plate 40 .

[0071] In this way, it is convenient for the user to apply force to the pressing portion 311 on the outer side of the cover plate 40 without removing the cover plate 40 , and the movement of the first latch 31 is more stable.

[0072] Specifically, the pressing portion 311 can be a bump protruding from the side wall of the first latch 31. The bump protrudes from the side wall of the cover plate 40 through the second through hole 41. The user can apply force to the bump, such as pressing downward, to drive the first latch 31 downward. Because the second through hole 41 is sufficiently long in the direction of movement of the first latch 31, it does not block the bump and does not affect the movement of the first latch 31.

[0073] In other embodiments of the present application, reference is made to Figure 8 and Figure 9 The insertion direction of the mortise and tenon structure intersects with the clamping direction of the first clamping member 31 and the second clamping member 211.

[0074] In this way, the positioning direction is different, making the position of the air filter more accurate and stable. The clamping direction is shown by the arrows in the figure, which are marked as D4 and D5 respectively in the figure.

[0075] Specifically, the connection direction of the mortise and tenon structure is the radial direction of the circumference of the fuselage 10 , and the clamping direction of the first clamping member 31 and the second clamping member 211 is the chord direction of the circumference side of the fuselage 10 .

[0076] In other embodiments of the present application, the second ends of the first air filter element and the second air filter element are provided with tenons, and the second mounting column is provided with mortises that cooperate with the tenons; the front ends of the tenons are provided with guiding inclined surfaces or curved surfaces.

[0077] In this way, during installation, there is a guiding inclined surface or arc surface to guide, which makes installation faster.

[0078] In some other embodiments of the present application, the body 10 further includes a base 12 located at the bottom end of the body 10 in the first direction; the bottom end of the air filter element abuts against the base 12 .

[0079] In this way, the position of the air filter element is not only limited in the circumferential direction, but also relatively reliably limited in the axial direction.

[0080] In other embodiments of the present application, reference is made to Figure 1 , air purifier includes:

[0081] The diffusion device 90 diffuses the filtered air over a long distance. The diffusion device 90 is located above the air purifier, and the air inlet of the diffusion device 90 is connected to the air outlet 112.

[0082] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations of the technical solutions of this application. Various modifications and variations may be made based on the above embodiments without departing from the scope disclosed herein. Similarly, the various technical features of the above embodiments may be arbitrarily combined to form additional embodiments of the present application that may not be explicitly described. Therefore, the above embodiments merely represent several implementations of the present application and do not limit the scope of protection of the patent application.
