Description

Technical Field

[0001] This utility model relates to a purification device, specifically an indoor air purification device, and belongs to the technical field of air purification devices. Background Technology

[0002] An indoor air purifier is a device used to improve indoor air quality. Its core function is to remove pollutants from the air through physical, chemical, or biological means, so that the air meets the standards suitable for human respiration. In household air purifiers, physical filtration technology is often used to purify the air. For example, by using an air filter element, which has a fiber interwoven structure, the filtration efficiency for particles larger than 0.3 microns can reach 99.97%, making it a key component for removing PM2.5 and dust.

[0003] A Chinese utility model patent (publication number: CN218179165U) discloses an indoor air purification device. It uses a centrifugal fan in the top of the fan base to allow outside air to enter the ventilation hood, be filtered by the air filter, and be adsorbed by activated carbon in the purification hood to remove pollutants from the air. The air can enter from the four sides of the ventilation hood and be filtered by the air filter. The honeycomb activated carbon has low wind resistance, which allows the air to pass through quickly without generating noise. The low wind resistance allows the air to pass through quickly to complete the purification.

[0004] While it effectively filters and purifies the air, its air filter replacement process has significant drawbacks. When replacing the filter, users need to disassemble the entire unit into upper and lower parts, involving complex clips and screws. This tedious disassembly process is not only time-consuming and labor-intensive but also requires a certain level of dexterity from the user. For users lacking relevant experience, improper operation can easily lead to equipment malfunction, greatly affecting ease of use and maintenance efficiency. Therefore, an indoor air purification device is proposed. Utility Model Content

[0005] In view of this, the present invention provides an indoor air purification device to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0006] The technical solution of this utility model embodiment is implemented as follows: an indoor air purification device includes a disassembly assembly, which includes a ventilation base, a cover plate, a rotating seat, a bearing, a trapezoidal top block, a support sleeve, a spring, a support seat, and a toggle block;

[0007] Magnetic strips are embedded in the opposite surfaces of the cover plate and the ventilation base. The cover plate is attracted to the ventilation base by the magnetic strips. The shape of the cover plate is adapted to the shape of the ventilation base. The support sleeve is fixedly connected to the inner bottom wall of the ventilation base. The support seat is slidably connected to the inner side wall of the support sleeve. The spring is located inside the support sleeve. The rotating seat is rotatably connected to the top of the outer side wall of the support sleeve through a bearing. The trapezoidal top block is fixedly connected to the inner top wall of the rotating seat and the upper surface of the support seat, respectively. The actuating block is fixedly connected to the outer side wall of the rotating seat.

[0008] More preferably, the bottom end of the spring abuts against the inner bottom wall of the ventilation base, and the top end of the spring abuts against the lower surface of the support base.

[0009] More preferably, the rotating seat is attached to the upper surface of the support seat by a trapezoidal top block.

[0010] More preferably, the ventilation base has a filter element inside, and the bottom end of the filter element is attached to the upper surface of the support base.

[0011] More preferably, the upper surface of the ventilation base is fitted with an upper mounting base by a snap-fit ​​mechanism.

[0012] More preferably, a guide fan is installed on the inner top wall of the upper mounting base, and an air guide pipe is fixedly connected inside the upper mounting base. The top end of the air guide pipe is connected to the guide fan, and a sealing ring is fixedly connected to the bottom end of the air guide pipe.

[0013] More preferably, the air duct is attached to the upper surface of the filter element by a sealing ring.

[0014] More preferably, a protective net is installed on the upper surface of the upper mounting base, and the position of the protective net corresponds to the position of the guide fan.

[0015] The present invention has the following advantages due to the adoption of the above technical solution:

[0016] When replacing the filter element, this invention involves pulling the cover plate to separate it from the ventilation base, then rotating the actuating block. Under the action of the upper and lower trapezoidal top blocks, the support base moves downward inside the support sleeve, separating the top of the filter element from the air duct. At this point, the filter element can be removed and replaced with a new one. The new filter element is then placed on the support base, and the actuating block is rotated counterclockwise. Under the push of the spring, the filter element is kept in contact with the air duct by the sealing ring, thus completing the filter element replacement. Compared with the prior art, this invention facilitates filter element replacement by setting up a disassembly component. During the replacement process, there is no need to deal with clips, screws, or other structures, reducing the difficulty of operation and improving the convenience of use and maintenance efficiency.

Detailed Implementation

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figures 1-5As shown, this utility model embodiment provides an indoor air purification device, including a disassembly assembly 101. The disassembly assembly 101 includes a ventilation base 11, a cover plate 13, a rotating seat 14, a bearing 16, a trapezoidal top block 17, a support sleeve 18, a spring 19, a support seat 20, and a toggle block 21.

[0028] Magnetic strips 15 are embedded on the opposite surfaces of the cover plate 13 and the ventilation base 11. The cover plate 13 is attracted to the ventilation base 11 through the magnetic strips 15. The shape of the cover plate 13 is adapted to the shape of the ventilation base 11. The cover plate 13 is installed by magnetic attraction, which ensures structural stability and facilitates the disassembly or installation of the cover plate 13. Air inlet holes are provided on both the ventilation base 11 and the cover plate 13.

[0029] The support sleeve 18 is fixedly connected to the inner bottom wall of the ventilation base 11, and the support seat 20 is slidably connected to the inner side wall of the support sleeve 18. The inner side wall of the support sleeve 18 is symmetrically provided with guide ribs (not shown in the figure) to limit the position of the support seat 20. The support seat 20 can slide up and down inside the support sleeve 18.

[0030] The rotating seat 14 is rotatably connected to the top of the outer wall of the support sleeve 18 via the bearing 16. The trapezoidal top block 17 is fixedly connected to the inner top wall of the rotating seat 14 and the upper surface of the support seat 20 respectively. The rotating seat 14 is attached to the upper surface of the support seat 20 via the trapezoidal top block 17. When the rotating seat 14 is rotated, the rotating seat 14 drives the trapezoidal top block 17. At this time, the trapezoidal top block 17 on the rotating seat 14 contacts the trapezoidal top block 17 on the support seat 20. Under the action of the upper and lower trapezoidal top blocks 17, the support seat 20 is pushed downward and moves downward inside the support sleeve 18.

[0031] The actuating block 21 is fixedly connected to the outer wall of the rotating seat 14, and the rotating seat 14 can be rotated conveniently by the actuating block 21.

[0032] In one embodiment, the spring 19 is located inside the support sleeve 18, with the bottom end of the spring 19 abutting against the inner bottom wall of the ventilation base 11 and the top end of the spring 19 abutting against the lower surface of the support seat 20. Under the push of the spring 19, the support seat 20 always bears an upward force.

[0033] In one embodiment, a filter element 12 is disposed inside the ventilation base 11, and the bottom end of the filter element 12 is attached to the upper surface of the support base 20, which is used to define the bottom position of the filter element 12.

[0034] In one embodiment, an upper mounting base 31 is installed on the upper surface of the ventilation base 11 by snap-fit, and the upper mounting base 31 is used to define the position of the guide fan 33 and the air guide duct 34.

[0035] A guide fan 33 is installed on the inner top wall of the upper mounting base 31. An air guide pipe 34 is fixedly connected inside the upper mounting base 31. The top end of the air guide pipe 34 is connected to the guide fan 33, and a sealing ring 35 is fixedly connected to the bottom end of the air guide pipe 34. The air guide pipe 34 is attached to the upper surface of the filter element 12 through the sealing ring 35. When the guide fan 33 is working, the outside air enters the inside of the device through the air inlet holes in the ventilation base 11 and the cover plate 13, and then is discharged along the air guide pipe 34 after being purified by the filter element 12.

[0036] Driven by the spring 19, the support base 20 always bears an upward force, which pushes the filter element 12 upward. The filter element 12 is kept in contact with the air duct 34 by the sealing ring 35, which can enhance the sealing effect and ensure the efficiency of air purification.

[0037] The guide fan 33 and filter element 12 are both existing technologies, so their working principle, internal structure, connection and control methods will not be described in detail.

[0038] In one embodiment, a protective net 32 ​​is installed on the upper surface of the upper mounting base 31. The position of the protective net 32 ​​corresponds to the position of the guide fan 33. The protective net 32 ​​can play a protective role and prevent the user from accidentally touching the guide fan 33.

[0039] When this utility model is in operation: the guide fan 33 is turned on, and at this time, the outside air enters the interior of the device through the air inlet holes in the ventilation base 11 and the cover plate 13. After being purified by the filter element 12, it is discharged along the air guide pipe 34, thereby achieving air purification.

[0040] When the filter element 12 needs to be replaced, pull the cover plate 13 to separate it from the ventilation base 11, and then rotate the actuating block 21 clockwise. The actuating block 21 drives the rotating seat 14 to rotate. At this time, the trapezoidal top block 17 on the rotating seat 14 contacts the trapezoidal top block 17 on the support seat 20. Under the action of the upper and lower trapezoidal top blocks 17, the support seat 20 moves downward inside the support sleeve 18, and the top of the filter element 12 separates from the air guide duct 34, so that the tops of the upper and lower trapezoidal top blocks 17 contact each other. At this point, filter element 12 can be removed and replaced with a new filter element. Place the new filter element 12 on the support base 20, align the top of filter element 12 with the air duct 34, and then rotate the toggle block 21 counterclockwise to separate the upper and lower trapezoidal top blocks 17. Under the push of the spring 19, the support base 20 pushes the filter element 12 upward. The filter element 12 is kept in contact with the air duct 34 by the sealing ring 35. Then, the cover plate 13 is attracted to the ventilation base 11. At this point, the filter element 12 has been replaced.

[0041] Compared with the prior art, this utility model facilitates the replacement of the filter element 12 by setting up a disassembly component 101. During the replacement process, there is no need to deal with structures such as clips and screws, which reduces the difficulty of operation and improves the convenience of use and maintenance efficiency.

[0042] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
