Description

Technical Field

[0001] The utility model relates to a new type of air purifier, belonging to the purification field. Background Art

[0002] The challenges in improving the performance of air purifiers are multifaceted. First of all, increasing the fan speed can indeed increase the air circulation volume, but this will inevitably bring noise problems. Especially in places where a quiet environment is required, such as bedrooms or libraries, the increase in noise will directly affect the user's comfort and experience. In addition, the increase in fan speed will also impose a greater burden on the motor, which may lead to a shortened lifespan of the motor and an increase in maintenance costs.

[0003] Based on the problems of the existing technology, the main drawbacks are as follows:

[0004] (1) Noise problem: Increasing the fan speed to increase the air circulation volume is a common method to improve performance, but this will inevitably increase noise and affect the user's experience. When expanding the air inlet, it is bound to increase the volume of the entire device;

[0005] (2) Energy consumption problem: Increasing the fan speed or enlarging the filter area will increase energy consumption, which not only increases the user's electricity bill but also does not conform to the environmental protection concept of energy conservation and emission reduction.

[0032] The present utility model will be further described below in conjunction with specific embodiments, and the advantages and features of the present utility model will become clearer with the description. However, these embodiments are merely exemplary and do not constitute any limitation to the scope of the present utility model. Those skilled in the art should understand that without departing from the spirit and scope of the present utility model, modifications or replacements can be made to the details and forms of the technical solution of the present utility model, but these modifications and replacements all fall within the protection scope of the present utility model.

[0033] Referring to Figures 1 to 7 , the present utility model relates to a new type of air purifier, which includes a front panel assembly 1, a middle frame assembly 3, an air guiding assembly 4, and a rear shell assembly 5. The front panel assembly 1 is detachably installed at the front part of the middle frame assembly 3, and the rear shell assembly 5 is detachably installed at the rear part. An air guiding assembly 4 is installed between the rear shell assembly 5 and the middle frame assembly 3. A filter assembly 2 corresponding to the air guiding assembly 4 is installed in the middle frame assembly 3. A main air inlet communicating with the air guiding assembly 4 is formed between the front panel assembly 1 and the middle frame assembly 3. A main air outlet is formed at the upper part of the rear shell assembly 5. The air guiding assembly 4 includes an air guiding mounting plate, an air guiding ring 9, a fan 8, a fan support frame, and a flow guiding assembly. A fan mounting hole is provided on the air guiding mounting plate, and the air guiding ring 9 is installed on the air guiding mounting plate near the fan mounting hole, on the side of the air guiding ring 9 close to the filter assembly 2; the fan 8 is installed at the center of the fan mounting hole and is installed on the air guiding mounting plate through several fan support frames 21, and a spacing is formed between adjacent two fan support frames 21; the flow guiding assembly is installed on the air guiding mounting plate above the fan 8, on the side of the flow guiding assembly close to the rear shell assembly 5, for guiding the air flow generated by the fan 8.

[0034] Based on the above structural settings, the present utility model realizes:

[0035] Efficient air circulation: The main air inlet is communicated with the air guiding assembly 4 to ensure that air can smoothly enter the interior of the purifier. The main air outlet is located at the upper part of the rear shell assembly 5, which helps to effectively output the purified air and form a good air circulation.

[0036] Optimized fan layout: The fan 8 is installed at the central position of the air guiding mounting plate and fixed by the fan support frames 21. This layout helps to reduce vibration and noise, and at the same time maintain the stability and balance of the fan.

[0037] Application of the air guiding ring 9: The setting of the air guiding ring 9 helps to guide air to flow more evenly towards the fan 8, reduce the resistance of air flow, and improve the air flow efficiency and filtration effect.

[0038] Innovation of the air guiding component: The air guiding component is installed on the air guiding installation plate above the fan 8, close to one side of the rear shell component 5, and can effectively guide the airflow generated by the fan 8.

[0039] Effective cooperation of the filter component 2: The filter component 2 corresponds to the air guiding component 4 to ensure that the air can be efficiently filtered by the filter after passing through the air guiding component, removing pollutants in the air.

[0040] Noise reduction: By optimizing the designs of the fan 8 and the air guiding component, the turbulence and eddy currents generated during air flow can be reduced, thereby reducing noise and providing a quieter operating environment.

[0041] The described air guiding component includes a guiding inclined plate 14 and an arc-shaped plate 15 integrally formed with the guiding inclined plate 14. The upper end of the guiding inclined plate 14 extends to the main air outlet 6, the lower end of the guiding inclined plate 14 is smoothly transitionally connected to one end of the arc-shaped plate 15, the arc-shaped plate 15 is arranged along the circumferential direction of the air outlet of the fan, and a spacing is formed between the arc-shaped plate 15 and the air outlet of the fan. The angle of the described air guiding component is adjustable.

[0042] The advantages of this air guiding component are as follows:

[0043] Airflow directivity: The upper end of the guiding inclined plate 14 extends to the main air outlet 6, which helps to buffer and guide the airflow generated by the fan 8 to the air outlet;

[0044] Smooth transition: The lower end of the guiding inclined plate 14 is smoothly transitionally connected to the arc-shaped plate 15. This design can reduce the turbulence generated at the turning point of the airflow, reduce noise, and improve the stability of the airflow.

[0045] Circumferential setting: The arc-shaped plate 15 is arranged along the circumferential direction of the air outlet of the fan. This annular air guiding design helps to evenly distribute the airflow and improve the overall purification efficiency.

[0046] The described main air inlet includes a side air inlet 17 and a bottom air inlet 16. One of the side air inlets is respectively arranged on both sides between the front panel component 1 and the middle frame component 3, and the bottom air inlet is arranged at the bottom between the front panel component 1 and the middle frame component 3; an air outlet grille is installed at the main air outlet 6 of the rear shell component 5, realizing air intake from multiple wind directions.

[0047] There are four fan support frames 21, which are evenly arranged along the circumferential direction of the fan installation holes. A fan air inlet 10 is formed between adjacent two fan support frames; the four fan support frames 21 are evenly arranged along the circumferential direction of the fan installation holes. This layout helps to provide the stability and balanced support of the fan 8, reduce the vibration and noise caused by uneven force, increase the air intake volume, and reduce the resistance.

[0048] The air inlet 10 of the fan formed between two adjacent fan support frames 21 helps to guide air into the fan evenly, improve the air flow efficiency, and reduce the air flow resistance.

[0049] The filter assembly 2 includes a filter frame 18, on which a primary filter layer, a secondary HEPA filter layer 18, and an activated carbon layer 20 are successively laminated. The air flow enters the filter assembly 2 through the side air inlet and the bottom air inlet between the front panel assembly 1 and the middle frame assembly 3 of the air purifier, then enters the fan air inlet 10 from the filter assembly 2, and finally flows out from the main air outlet 6 after flowing through the fan 8.

[0050] When the opening area of the fan air inlet 10 is 150 cm 2 , the performance of the air purifier is relatively low and does not meet the requirements.

[0051] When the opening area of the volute air inlet 10 is 235 cm 2 , the performance of the air purifier is greatly improved and meets the requirements.

[0052] In view of the above situation and combined with the experimental test data of the product sample, in this example, it is finally confirmed that the opening area S of the volute air inlet 10 is 235 cm 2 .

[0053] The air guide ring 9 is arranged in a Venturi shape, which can not only increase the structural strength but also optimize the air flow in the flow channel, and solve the problems such as uneven air flow at the air inlet of the fan, poor air flow inside the fan, and significant eddy current impact noise.

[0054] The filter frame is installed on the middle frame assembly 3 through a filter lock 13.

[0055] A micro switch 11 is installed between the middle frame assembly 3 and the front panel assembly 1, and a safety switch 12 is installed between the middle frame assembly 3 and the filter assembly 2. The safety switch 12 and the micro switch 11 are electrically connected to the control panel. When the front panel assembly 1 is disassembled from the middle frame assembly 3, the micro switch 11 is powered off; when the filter assembly 2 is disassembled from the middle frame assembly 3, the safety switch 12 is powered off. When the safety switch 12 or the micro switch 11 is powered off, the control panel controls the fan to stop rotating.

[0056] The front panel assembly 1 is installed on the middle frame assembly 3 through magnets, and the middle frame assembly 3 and the rear shell assembly 5 are locked by screws.

[0057] The working principle of the present utility model is:

[0058] Air intake: Air enters the purifier through the main air inlet formed between the front panel assembly 1 and the middle frame assembly 3. This air inlet includes a side air inlet 17 and a bottom air inlet 16, thus achieving the introduction of air from multiple directions and increasing the air collection efficiency.

[0059] Primary filtration: The introduced air first passes through the filter assembly 2, which includes a filter frame 18, and is successively laminated with a primary filter layer, a secondary HEPA filter layer, and an activated carbon layer 20. These filter layers are responsible for removing large particulate matter, fine particles, and harmful gases in the air.

[0060] Fan suction: The filtered air enters the fan air inlet 10, which is formed by the spacing between four fan support frames 21. The fan 8 is fixed to the air guiding mounting plate through the fan support frames 21. The uniform distribution of the fan support frames helps to provide the stability and balanced support of the fan, reducing vibration and noise.

[0061] Airflow diversion: The airflow generated by the fan 8 is diverted through the diversion assembly. The diversion assembly includes a diversion inclined plate 14 and an arc plate 15 integrally formed therewith. The upper end of the diversion inclined plate 14 extends to the main air outlet 6, and the lower end is smoothly connected to the arc plate 15. The arc plate 15 is arranged along the circumference of the fan air outlet, forming an effective air flow guide.

[0062] Optimized airflow: The design of the diversion inclined plate 14 and the arc plate 15 helps to buffer and guide the airflow, reduce the turbulence generated at the turning point of the airflow, reduce noise, and improve the stability of the airflow. The angle of the diversion assembly is adjustable, allowing the adjustment of the airflow direction as needed to optimize the air flow.

[0063] Air output: The purified air flows out through the main air outlet 6 at the upper part of the rear shell assembly 5. The setting of the air outlet grille helps to control the direction and flow rate of the air output.

[0064] Safety mechanism: A micro switch 11 is installed between the middle frame assembly 3 and the front panel assembly 1, and a safety switch 12 is installed between the filter assembly 2 and the middle frame assembly 3. The safety switch 12 and the micro switch 11 are electrically connected to the control panel. When the front panel assembly 1 is disassembled from the middle frame assembly 3, the micro switch 11 is powered off. When the filter assembly 2 is disassembled from the middle frame assembly 3, the safety switch 12 is powered off. In both cases, the control panel can control the fan to stop rotating to ensure safe use.

[0065] Convenient installation and maintenance: The front panel assembly 1 is installed on the middle frame assembly 3 through magnets, simplifying the installation process. The middle frame assembly 3 and the rear shell assembly 5 are locked by screws to ensure structural stability. The filter frame is installed on the middle frame assembly 3 through a filter lock 13, facilitating replacement and maintenance.

[0066] Optimization of the air guiding ring 9: The air guiding ring 9 is arranged in a Venturi shape, which increases the structural strength, optimizes the airflow in the flow channel, and reduces the uneven airflow and vortex impact noise at the air inlet of the fan.

[0067] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
