Description
Technical Field
[0001] This utility model relates to the field of air purifier technology, and in particular to an air purifier for use in teaching aids and toys. Background Technology
[0002] Air contains fine particulate matter, such as PM2.5, dust, pollen, and pet dander. These particles, when suspended in the air for extended periods, can seriously impact human health. Air purifiers can significantly reduce the concentration of these particles indoors, thereby improving air quality. Air purifiers can also eliminate various harmful gases, such as formaldehyde, benzene, sulfur dioxide, and carbon monoxide. These gases are typically released from indoor decoration materials, furniture, and smoke; long-term inhalation can severely affect human health. They primarily rely on a fan and filter. The fan draws air into the machine, where particulate matter, odors, and toxic gases are adsorbed onto the filter, thus purifying the air. Air purifiers are usually equipped with activated carbon filters or other chemical adsorption materials to effectively adsorb and decompose these harmful gases.
[0003] Air purifiers used in teaching and as toys need to have good detachable and assembleable functions so that students can assemble them themselves to effectively complete teaching tasks. Currently, commercially available air purifiers used in teaching mainly use KT boards or wooden boards to assemble the outer shell. Air is drawn in by a rotating turbine fan inside the purifier, and then a mesh screen is used to block particulate matter in the air, thus achieving the effect of air purification.
[0004] However, among these products, KT boards are easily damaged, wooden boards are prone to burrs, and there is no filter layer, only a single layer of mesh, which does not conform to the actual principle of air purifiers. Furthermore, the boards are not easy to disassemble, making it impossible to clearly demonstrate the components and working principle of air purifiers to students, resulting in poor teaching effectiveness.

[0035] Example 1
[0036] like Figures 1-12As shown, this utility model provides an air purifier for teaching aids and toys, including a lower cover 1, an upper cover 2, a box body 3, and a box lid 4; the upper cover 2 is connected to the lower cover 1 by a first connector 5, the box body 3 is connected to the upper cover 2 by a second connector 6, and the box lid 4 is detachably installed on the box body 3; the openings of the lower cover 1 and the upper cover 2 form an accommodating space 7, a power supply device 8 is installed in the accommodating space 7, a motor device 9 and a fan blade device 10 are installed on the upper cover 2 in the lower part of the box body 3, a filter device is provided in the upper part of the box body 3, and air holes 15 are opened on the side wall of the box body 3.
[0037] Specifically, the lower cover 1 and the upper cover 2 form a base, and the power supply device 8 is placed and fixed in the accommodating space 7 formed by the lower cover 1 and the upper cover 2, which separates the power supply device 8 from the air filtration space inside the box 3, protecting the power supply device 8 from accumulating filter impurities. Moreover, the power supply device 8 is independent. When the lower cover 1 and the upper cover 2 are disassembled during teaching, students can observe the composition of the power supply system more intuitively.
[0038] The box body 3 and the top cover 2 are detachably connected by the second connector 6. During teaching, after the box body 3 is disassembled, students can directly observe the composition of the motor device 9 and the fan blade device 10 installed on the top cover 2.
[0039] The filter device is installed inside the upper part of the housing 3 and is fixed by the housing cover 4. The housing cover 4 can be placed directly on the housing 3, making it easy to remove and replace the HEPA filter 11 in the purifier. During teaching, after opening the housing cover 4, students can directly observe the composition of the filter device and replace it. Air is introduced through the air holes 15 on the side wall of the housing 3, forming an air passage with the filter device, allowing students to understand the air purification process.
[0040] Example 2
[0041] The lower cover 1, upper cover 2, box body 3, and box lid 4 are all ABS injection molded parts. The filtration device includes a HEPA filter 11.
[0042] Specifically, the box body 3 and the lid 4 are made of ABS injection molding and are white in color; the lower cover 1 and the upper cover 2 are made of ABS injection molding and are brown in color; the ABS injection molding parts have a smooth surface without burrs and are sturdy and not easily damaged. The HEPA filter 11 can be directly removed and placed for easy display.
[0043] Example 3
[0044] The power supply device 8 includes a switch module 801 and an interface module 802. Switch module slots 12 and interface module slots 13 are located at the same position on the side walls of the lower cover 1 and the upper cover 2. The switch module 801 is embedded between the switch module slots 12 of the lower cover 1 and the upper cover 2, and the interface module 802 is embedded between the interface module slots 13 of the lower cover 1 and the upper cover 2. The switch module 801 and the interface module 802 are electrically connected via wires 14. The upper cover 2 has a dot-matrix pattern of mounting holes 201. The motor device 9 includes a motor and a motor mount. The motor and the motor mount are connected by screws, and the motor mount is connected to the mounting holes 201 via screws. The motor and the interface module 802 are electrically connected via wires 14. The fan blade device 10 is connected to the motor shaft. The first connecting member 5 includes a hook-shaped cantilever buckle 501 connected to the side wall of the lower cover 1 and a latch 502 opened on the side wall of the upper cover 2.
[0045] Specifically, switch module 801 is a power switch module 801, and interface module 802 is a TYPE-C interface module 802. The TYPE-C interface module 802 obtains 5V DC power via USB and supplies power to the base power switch via interface P1. The base power switch module 801 mainly consists of a microcontroller U1, button K1, MOSFET M1, and other components such as resistors and capacitors. When K1 is pressed, a high-level signal is transmitted to the IN port of U1. U1 controls the OUT port to output a low-level signal, turning on M1. This outputs 5V voltage through pin SI of interface P1 to pin SI of the TYPE-C interface P1. Pin SI of interface P1 is also connected to pin 1 of interfaces P2 and P3, supplying power to subsequent circuit modules. When button K1 of the base power switch is pressed again, U1 outputs a high-level signal, MOSFET M1 is turned off, and power supply stops.
[0046] The switch module slot 12 is a 1.7cm arc-shaped groove used to house the power switch module 801 and the button cap. The button cap prevents direct hand contact with the power switch module 801, extending the lifespan of the circuit board and facilitating student use. The interface module slot 13 has two screw slots and a 1cm opening slot for housing the TYPE-C interface module 802. The TYPE-C interface module 802 needs to be fixed to the copper pillar groove with screws. After the upper cover 2 and lower cover 1 are fixed together, only the TYPE-C interface is visible from the outside, improving aesthetics and simplicity. The lower cover 1 and upper cover 2 have through screw holes at their four corners, which can be used to fix other components.
[0047] The lower cover 1 has upward-protruding hook-shaped cantilever buckles 501 on the other two sides where there are no slots, which are used to connect with the buckles 502 of the upper cover 2. The upper cover 2 has four recessed buckles 502 at the same position, which are fixed with the buckles 501.
[0048] The top cover 2 has dot-matrix mounting holes 201 with a gap of 0.5cm, which increases DIY expandability and ease of use. There are two 0.7cm*0.4cm DuPont wire connectors on the TYPE-C interface side for connecting to the TYPE-C interface module 802 below.
[0049] Example 4
[0050] The box body 3 includes a first half-box 301 and a second half-box 302, which are joined together to form the box body 3. Upper connecting posts 304 are provided at the internal corners of the first half-box 301 and the second half-box 302. Lower connecting posts 101 are provided at the four corners of the lower cover 1 and the upper cover 2. The second connecting member 6 includes screws, which are inserted into the lower cover 1 and threadedly connect the lower connecting posts 101 and the upper connecting posts 304. A stepped placement hole 303 is provided in the upper center of the box body 3, and the filter device is placed inside the placement hole 303. Multiple air holes 15 are arrayed on the lower side wall of the box body 3, with the diameter of the air holes gradually increasing downwards along the height direction. Air holes 15 are distributed in a petal-like pattern on the lid 4.
[0051] Specifically, box body 3 features a two-part snap-fit design (501). The sides of box body 3 have 0.3cm hexagonal grooves and 0.2cm circular protrusions. Combining the different shaped grooves and protrusions makes the assembly more stable. Box body 3 is perfectly symmetrical, ensuring consistent dimensions. Each corner of box body 3 has a 0.7cm diameter, 6.7cm high cylinder with 0.3cm screw holes inside. Box body 3 is 0.2cm thick, ensuring quality and durability.
[0052] After the air purifier body 3 is assembled, it forms a cube with sides of 9.4cm and a height of 7cm. Once fixed in place, there is a 3cm recessed circular hole in the center with an outer diameter of 8cm and an inner diameter of 7cm. This design prevents the filter from falling down, and the hole size is suitable for most HEPA filters on the market. At the top, there are four 0.2cm circular protrusions distributed at 7.5cm sides, and 1.5cm curved grooves on both sides for securing it to the lid 4. At the bottom 4.5cm of the body 3, there are four rows of 15 air vents spaced 0.3cm apart, increasing in size towards the bottom in a diamond pattern, for expelling air.
[0053] The lid 4 has petal-shaped holes distributed outwards, which is aesthetically pleasing and allows air to be drawn in. When the lid 4 is assembled with the box body 3, the recessed area of the lid 4 is arc-shaped, providing a certain gap for easy removal of the lid 4. Furthermore, the four recessed holes on the lid 4 correspond to the raised holes on the box body 3, increasing stability.
[0054] Assembly process of the air purifier of this utility model:
[0055] First, connect the power switch module 801 to the TYPE-C interface module 802 using a 3-pin cable. Then, place the power switch module 801 and the button cap on one side of the arc-shaped groove of the lower cover 1 of the standard base. The TYPE-C interface module 802 needs to be fixed to the other side with screws. Then, assemble the upper cover 2 and the lower cover 1.
[0056] Next, use screws to install the motor and motor mount in the middle of the standard base, and connect the motor wire 14 to any port of the TYPE-C interface module 802. Then, install the turbine fan on the motor shaft.
[0057] There are four screw holes at the bottom of the base, which are needed to secure the air purifier housing 3. Finally, place the HEPA filter 11 and the air purifier housing cover 4.
[0058] The working principle of this air purifier is as follows: It uses a TYPE-C cable to connect to the TYPE-C interface module 802. The power switch on the base controls whether the power is on. When it is turned on, the motor starts and drives the turbine fan device 10 to rotate. Due to the structure of the turbine fan device 10, air is drawn in from the top of the purifier. After the particulate matter is blocked by the filter, it is discharged from the holes at the bottom, resulting in clean air.
[0059] This utility model air purifier features a simple and aesthetically pleasing design. It is composed of independent components including a TYPE-C module, a detachable base, a power switch module 801, a housing 3, a motor, a motor mount, a turbine fan blade assembly 10, a HEPA filter 11, and a cover 4. Operating according to the principles of a typical air purifier, it offers advantages such as easy assembly and disassembly and a clear understanding of its operating principles. The materials are safe, and screws are used for secure fixing, increasing stability and facilitating teaching activities.
[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
