Description

Technical Field

[0001] This invention relates to the field of air purification technology, and more specifically, to a high-efficiency intelligent air purification device for use in neurology wards. Background Technology

[0002] Patients in the neurology ward have low immunity and extremely low noise tolerance. Therefore, the air purification device needs to be able to effectively intercept tiny particles (droplet nuclei, viral aerosols), operate quietly, and adapt to different operating conditions. In practical applications, the ward has two operating conditions: sudden high pollution (patient cough, disinfection) and daily low pollution. The device needs to switch purification modes to balance the effect and the need for quiet operation.

[0003] Most existing air purification devices use fixed-arrangement multi-layer filters to intercept fine particles. They rely on the physical sieving of the filter fibers for filtration. When the airflow passes through the filter in a straight line, there are no controllable gaps between the layers, so turbulence cannot be formed. Even if a few devices have a filter shaking function, it is only used for simple dust shaking. It does not use the shaking and gap airflow coupling to generate turbulence to achieve secondary interception of fine particles. As a result, 0.3-1μm fine particles can easily pass through the filter, making it difficult to prevent cross-infection.

[0004] Furthermore, when switching between high and low pollution purification modes, the air purifier only adjusts the fan power without adjusting the air outlet area. In high pollution mode, the fan power is increased, and the fixed air outlet can easily lead to a sudden increase in air pressure in the duct and excessive noise. In low pollution mode, the fan power is reduced, and the fixed air outlet results in insufficient contact between the airflow and the filter, reducing purification efficiency and failing to meet the adaptive quiet and purification requirements of the ward. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-efficiency intelligent air purification device for neurology wards.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A high-efficiency intelligent air purification device for use in a neurology ward, the air purification device comprising:

[0008] An integrated housing, wherein a sealing cover is provided on the integrated housing to seal its top, and an air inlet and an air outlet are provided on the integrated housing, and an adjustment mechanism for adjusting the air outlet area is provided at the air outlet;

[0009] A filter assembly is disposed within an integrated housing. The filter assembly includes multiple sets of parallel and equidistantly arranged filter units. Each filter unit consists of a filter element and a U-shaped frame slidably disposed on the outside of the filter element.

[0010] The filter element includes a filter screen, a rectangular frame, and a silicone cloth. The upper and lower sides of the filter screen are fixedly connected to the rectangular frame through the silicone cloth. A connecting shaft that is rotatably connected to the rectangular frame is fixed at the center of the left and right sides of the filter screen.

[0011] Furthermore, barrier sponges are provided in the gaps between the left and right sides of the filter screen and the rectangular frame, and the barrier sponges are adhered to the side walls of the rectangular frame, with the size of the barrier sponges corresponding to the size of the side walls of the rectangular frame.

[0012] Furthermore, one set of the U-shaped frames near the air inlet is fixedly connected to the inner wall of the integrated housing, while the other sets of U-shaped frames are slidably fitted to the inner wall of the integrated housing.

[0013] Furthermore, the two adjacent sets of the U-shaped frames are connected by a pair of electric push rods. The pair of electric push rods are symmetrically distributed on both sides of the U-shaped frame, and the direction from the air outlet to the air inlet is the direction in which the extended end of the electric push rod retracts.

[0014] Furthermore, a set of limiting components for limiting the shaking of the filter screen is provided at each of the four corners of the inner wall of the rectangular frame. The limiting components include two sets of torque limiting blocks, and the vertical distance between each set of torque limiting blocks is greater than the thickness of the filter screen.

[0015] Furthermore, the adjustment mechanism includes two sets of adjustment rods arranged on the same side that slide in cooperation with the inner wall of the integrated housing. One end of the adjustment rod is fixedly connected to a set of U-shaped frames near the air outlet. The other end of the adjustment rod is fixedly provided with a rack plate, and a sliding groove is provided on the integrated housing to limit the sliding of the rack plate. Gears are meshed on the outer side of the rack plate, and the two sets of gears are fixedly connected by a threaded rod.

[0016] Furthermore, the end of the threaded rod is rotatably engaged with the integrated housing via a bearing, and the threaded rod is externally threaded with multiple sets of parallel-installed fixing plates, which are connected together by a blocking adjustment plate to block the air outlet.

[0017] Furthermore, the filter assembly divides the integrated housing into a pretreatment chamber and a sterilization and purification chamber. The pretreatment chamber is connected to the air inlet and is equipped with an antibacterial and washable pre-filter cotton module. The sterilization and purification chamber is equipped with a safety sterilization and disinfection module, an odor adsorption and decomposition module, and a silent fan, sequentially inserted on the inner wall from near the air inlet to far away from the air outlet.

[0018] The technical effects and advantages of this invention are as follows:

[0019] 1. This invention uses a multi-layer filter screen with a controllable narrow gap between the layers and a limiting position. The filter screen is elastically connected and has a central limiting structure design, which enables a slight sway driven by the wind speed of a silent fan. Finally, through the coupling and synergistic effect of the gap turbulence disturbance and the dynamic sway of the filter screen, the dual functions of secondary interception of small particles and self-cleaning and anti-clogging between layers are achieved simultaneously.

[0020] 2. This invention achieves the state switching of "parallel and equidistant - superimposed and overlapping" by driving multiple U-shaped frames with electric push rods; at the same time, the frame movement is linked to the air outlet shielding adjustment plate through gears and rack plates to achieve the mechanical linkage of "filter unit superposition → air outlet opening wide, filter units parallel → air outlet shrinking", matching the air volume and air pressure requirements under high / low pollution conditions, and ensuring the balance between purification efficiency and quiet effect.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figures 1-9 As shown, the following solutions can be used to address the problem that existing technologies cannot generate turbulence through shaking and gap airflow coupling to achieve secondary interception of microparticles, which makes it easy for microparticles to penetrate the filter and difficult to prevent cross-contamination.

[0034] This embodiment provides a high-efficiency intelligent air purification device for use in a neurology ward. The air purification device includes: an integrated housing 1 and a filter assembly 5.

[0035] The integrated housing 1 is provided with a sealing cover 2 to seal its top. The sealing cover 2 and the integrated housing 1 are interference fit to ensure the sealing performance in the closed state. The integrated housing 1 is provided with an air inlet 9 and an air outlet 3. An adjustment mechanism for adjusting the air outlet area is provided at the air outlet 3 to realize the dynamic adaptive adjustment of the cross-sectional area of ​​the air outlet 3.

[0036] The filter assembly 5 is disposed within the integrated housing 1. The filter assembly 5 includes multiple sets of parallel and equidistantly arranged filter units. Each filter unit consists of multiple sets of filter elements and a U-shaped frame 52 that is slidably disposed on the outside of the filter elements.

[0037] The filter element includes a filter screen 53, a rectangular frame 54, and a silicone cloth 55. The upper and lower sides of the filter screen 53 are fixedly connected to the rectangular frame 54 through the silicone cloth 55. The center of the left and right sides of the filter screen 53 is fixedly provided with a connecting shaft 56 that is rotatably connected to the rectangular frame 54. The gaps between the left and right sides of the filter screen 53 and the rectangular frame 54 are provided with barrier sponges 57, and the barrier sponges 57 are adhered to the side walls of the rectangular frame 54. The size of the barrier sponges 57 corresponds to the size of the side walls of the rectangular frame 54 to ensure the sealing between the filter screen 53 and the rectangular frame 54 and prevent unfiltered airflow from leaking from the gaps.

[0038] To further explain this embodiment, the dimensions of the silicone cloth 55 must precisely match the connection area of ​​the filter screen 53 and the rectangular frame 54. The specific setting standards are as follows:

[0039] Length: The length of the silicone cloth 55 is consistent with the left and right width of the filter screen 53, ensuring that there are no gaps between the upper and lower edges of the filter screen 53 and the rectangular frame 54.

[0040] Width: The width of silicone cloth 55 is 8-12mm. The width value must meet two core conditions: first, provide sufficient elastic deformation space, and second, avoid excessive deformation leading to fatigue damage.

[0041] Thickness: 0.3-0.5mm ultra-thin wear-resistant silicone cloth 55 is selected, which combines elasticity and weather resistance, is suitable for the disinfection environment of neurology wards, and can withstand wiping with alcohol and chlorine-containing disinfectants;

[0042] This embodiment further explains the principle behind the shaking of the filter screen 53.

[0043] The core function of the silicone cloth 55 is elastic connection and reset traction. Together with the rotation constraint of the connecting shaft 56 and the limiting of the torque limiting block 58, it achieves controllable micro-shaking of the filter screen 53. The specific process is as follows:

[0044] When the airflow passes through the filter unit, the wind speed generates a thrust on the filter plate 53, causing the filter plate 53 to rotate around the connecting shafts 56 on the left and right sides. During the rotation of the filter plate 53, the silicone cloth 55 is stretched, and the elastic deformation of the silicone cloth 55 generates a reverse rebound force. The torque limiting block 58 limits the maximum rotation angle of the filter plate 53 to 5°-10° to avoid excessive rotation that could cause the silicone cloth 55 to tear. When the airflow pressure fluctuates with the turbulence, the rebound force of the silicone cloth 55 causes the filter plate 53 to reset, thus forming a reciprocating micro-sway, and finally forming a controlled turbulent vortex at the gap between the layers of the filter plate 53.

[0045] This embodiment further illustrates the optimized pore size design of the filter screen 53.

[0046] The filter screen 53 needs to adopt a graded gradient design for its pore size to adapt to the mixed pollution scenario of "large particulate dust + tiny microorganisms, aerosols, viruses, and droplet nuclei" in the neurology ward. The specific setting scheme is as follows:

[0047] The filter unit near the air inlet 9 uses a coarse filter with a pore size of 10-15μm and is made of polyester fiber. It prioritizes the interception of large particulate impurities such as dust and dander larger than 5μm, reducing the load on the downstream filter.

[0048] Intermediate layer filtration unit: It adopts a medium-efficiency activated carbon composite filter with a pore size of 3-5μm. The material is polyester fiber composite modified activated carbon particles. While intercepting fine dust of 3-5μm, it also initially adsorbs the odor of disinfectant in the ward.

[0049] The filter unit near the air outlet 3 uses an H13 grade high-efficiency activated carbon composite filter with a pore size of 0.3-0.5μm. The material is ultra-fine glass fiber composite activated carbon fiber felt. It can intercept tiny particles such as virus aerosols and droplet nuclei of 0.3-1μm, while deeply adsorbing residual odor molecules.

[0050] Optimization principles: The pore size of adjacent filter units decreases in a gradient, and the pore size difference is controlled within 2-12μm to avoid a sharp increase in airflow resistance caused by abrupt changes in pore size. In addition, all filter fiber surfaces are coated with a medical-grade nano antistatic hydrophobic coating to prevent particles from adhering to the fiber surface due to electrostatic adsorption and extend the filter cleaning cycle.

[0051] Please see Figures 2-3 As shown, a set of U-shaped frames 52 near the air inlet 9 is fixedly connected to the inner wall of the integrated housing 1, and multiple other sets of U-shaped frames 52 are slidably engaged with the inner wall of the integrated housing 1. To supplement the above, slide rail grooves are provided on the inner walls of both the left and right sides of the integrated housing 1 to limit the movement of the U-shaped frames 52. A magnetic sliding shaft is fixed to the side wall of the U-shaped frame 52, penetrating into the slide rail groove. An electromagnetic plate is embedded in the inner wall of the slide rail groove and magnetically attracted to the magnetic sliding shaft. The clearance between the magnetic sliding shaft and the slide rail groove is ≤0.1mm, ensuring that the U-shaped frame 52 moves smoothly without jamming. When the electric push rod 59 drives the U-shaped frame 52 to a preset position, i.e., the overlapping position or the parallel position, the electromagnetic plate is activated. The electromagnetic plate, through magnetic attraction with the magnetic sliding shaft, provides an attraction force of 50-80N, locking the position of the U-shaped frame 52 and preventing airflow impact from causing frame displacement, thus ensuring the stability of the interlayer gap.

[0052] Please see Figures 3-4As shown, two adjacent sets of U-shaped frames 52 are connected by a pair of electric push rods 59. The pair of electric push rods 59 are symmetrically distributed on both sides of the U-shaped frame 52, and the direction from the air outlet 3 to the air inlet 9 is the direction in which the extended end of the electric push rod 59 retracts. To supplement the above, a limiting groove is provided on the inner wall of the integrated housing 1 to limit the extension trajectory of the electric push rod 59. (Refer to...) Figure 4 The end of the electric push rod 59 is connected to a rectangular block that is adapted to the size of the limiting groove and slides in fit, so as to prevent gas from being directly discharged through the limiting groove;

[0053] The clearance between the rectangular block and the limiting groove is controlled at 0.05-0.1mm, and the overflow volume accounts for only 1%-3% of the total air volume, which has no significant impact on the overall purification efficiency and can be ignored.

[0054] Please see Figures 5-6 As shown, a set of limiting components for limiting the shaking of the filter screen plate 53 is provided at the four corners of the inner wall of the rectangular frame 54. The limiting components include two sets of torque limiting blocks 58, and the vertical distance between each set of torque limiting blocks 58 is greater than the thickness of the filter screen plate 53. Protective pads are attached to the opposite side walls of each set of torque limiting blocks 58 to avoid damaging the filter screen plate 53.

[0055] The protective pad is made of medical-grade silicone, which has the advantages of being wear-resistant, quiet, cushioning, and antibacterial. The thickness of the protective pad is 1-2mm.

[0056] The working principle of this embodiment one:

[0057] (i) High pollution fluctuation conditions, short-term enhanced purification

[0058] In response to sudden high-contamination scenarios such as patient coughing and ward disinfection, an external PLC control system controls the synchronous retraction of the extended ends of multiple sets of electric push rods 59, driving multiple sets of U-shaped frames 52 to translate along the slide rails. This causes multiple sets of filter units to translate, overlap, and merge with each other, maintaining a narrow gap of 0.3-0.8mm between the filter screens 53. Simultaneously, the power of the silent fan 6 is increased, allowing airflow to pass through the filter units at a high speed of 3-5m / s. When the airflow penetrates the filter units and passes through the narrow gaps, the filter screens 53 sway slightly under the influence of the wind speed. The airflow exerts a pushing force on the filter screens 53 as it passes through them, causing them to... Rotating around the connecting shaft 56, the elastic rebound force of the silicone cloth 55 drives the filter screen to reset, while the torque limiting block 58 precisely limits the rotation amplitude of the filter screen plate 53 to 5°-10°, ultimately causing the filter screen plate to form a high-frequency reciprocating oscillation of 10-15 times / second. The oscillation of the filter screen generates local turbulent eddies in the gaps, which change the linear trajectory of tiny impurities, causing particles that could originally pass through the pores of the filter screen plate 53 to be carried by the eddies and collide with the filter screen fibers, achieving secondary interception. The superimposed multi-layer filter screen fibers form a three-dimensional interception network, improving the filtration accuracy of the filter screen plate 53 and achieving rapid and efficient purification of sudden pollution.

[0059] (ii) For applications requiring low-pollution steady-state conditions and long-term continuous purification:

[0060] To meet the daily low-pollution, steady-state purification needs of wards, the external PLC control system controls multiple sets of electric push rods 59 to extend synchronously to their longest positions, driving multiple sets of U-shaped frames 52 to reset along the slide rails, so that multiple sets of filter units are restored to a parallel and equidistant arrangement. At this time, the power of the silent fan 6 automatically drops to 30%-50% of its rated power, and the airflow passes evenly across the entire surface of the filter screen 53 at a low wind speed of 1-1.5m / s. Due to the low wind speed, the thrust of the airflow on the filter screen 53 is significantly reduced, and the filter screen 53 only produces a weak amplitude sway of 1°-3° with a swaying frequency ≤3 times / second. Under this condition, the silicone cloth 55 only undergoes slight elastic deformation. With the limiting effect of the torque limiting block 58, the filtration area is maximized and the airflow resistance is minimized, ensuring stable purification efficiency, reducing fatigue wear of components such as the silicone cloth 55, extending the service life of the device, and meeting the long-term, low-fluctuation purification needs of wards.

[0061] By stacking and arranging multiple layers of filter screens 53 with controllable narrow gaps reserved between layers and limiting their position, the filter screens 53 achieve micro-oscillation driven by the wind speed adaptively by the silent fan 6 through the structural design of elastic connection and central limiting. Finally, through the coupling and synergistic effect of gap turbulence disturbance and dynamic oscillation of the filter screen, the dual functions of secondary interception of micro particles and self-cleaning and anti-clogging between layers are achieved simultaneously.

[0062] Example 2: Please refer to Figures 7-9 As shown, further explanations are provided based on Example 1;

[0063] The adjustment mechanism includes two sets of adjustment rods 61 that slide in cooperation with the inner wall of the integrated housing 1. One end of the adjustment rod 61 is fixedly connected to a set of U-shaped frames 52 near the air outlet 3. The other end of the adjustment rod 61 is fixedly provided with a rack plate 62. The integrated housing 1 is provided with a sliding groove for sliding limit of the rack plate 62. The outer side of the rack plate 62 is meshed with a gear 63. The two sets of gears 63 are fixedly connected by a threaded rod 64.

[0064] The end of the threaded rod 64 is rotatably engaged with the integrated housing 1 through a bearing. The threaded rod 64 is externally threaded to multiple sets of parallel-installed fixed plates 65. The multiple sets of fixed plates 65 are connected together to a shielding adjustment plate 66 that shields the air outlet 3.

[0065] The filter assembly 5 divides the integrated housing 1 into a pretreatment chamber and a sterilization and purification chamber. The pretreatment chamber is connected to the air inlet 9, and an antibacterial washable pre-filter cotton module 4 is inserted in the pretreatment chamber. The sterilization and purification chamber is provided with a safe sterilization and disinfection module 7, an odor adsorption and decomposition module 8, and a silent fan 6 on the inner wall from near the air inlet 9 to far away from the air outlet 3. The antibacterial washable pre-filter cotton module 4, the safe sterilization and disinfection module 7, the odor adsorption and decomposition module 8, and the silent fan 6 mentioned above are all existing technologies and will not be described in detail here.

[0066] The working principle in this second embodiment is as follows:

[0067] As the U-shaped frame 52 moves towards the air inlet 9, the two sets of adjusting rods 61 fixedly connected to it move synchronously towards the air inlet 9 along with the U-shaped frame 52. The adjusting rods 61 drive the rack plate 62 at the other end to slide smoothly along the preset groove of the housing. Since the rack plate 62 meshes with the gear 63, the linear motion of the rack plate 62 is converted into the rotational motion of the gear 63, which in turn drives the threaded rod 64 fixedly connected to the two sets of gears 63 to rotate synchronously around the deep groove ball bearing. When the threaded rod 64 rotates, the bidirectional trapezoidal thread on its surface drives the two sets of fixed plates 65 to move smoothly upward along the axial direction of the threaded rod 64. The fixed plates 65 drive the shielding adjusting plate 66 to lift upward synchronously, thereby increasing the air outlet area of ​​the air outlet 3. According to the set mechanical transmission ratio, when the U-shaped frame 52 moves to its maximum stroke, that is, when the filter units are fully stacked, the shielding adjustment plate 66 is raised to the highest position, and the air outlet 3 reaches 100% opening, fully open. At this time, the clean air after filtration, sterilization and deodorization can be quickly discharged, effectively releasing the excessively high wind pressure generated by the high power operation of the fan in the sterilization and purification chamber, avoiding the noise caused by the increased airflow turbulence in the air duct due to excessive wind pressure, ensuring that the noise of the device operation is ≤30dB, and ensuring a quiet environment in the neurology ward;

[0068] Conversely, during the repositioning and translation of the U-shaped frame 52, the adjusting rod 61 moves away from the air inlet 9 along with the U-shaped frame 52, causing the rack plate 62 to slide in the opposite direction along the slide groove, thereby driving the gear 63 and the threaded rod 64 to rotate in the opposite direction. When the threaded rod 64 rotates in the opposite direction, it drives the fixed plate 65 to move downward along the threaded rod 64 axis through the threaded transmission, and the shielding adjusting plate 66 falls downward simultaneously, reducing the air outlet area of ​​the air outlet 3. When the U-shaped frame 52 is fully repositioned, that is, when the filter units are parallel and equidistant, the shielding adjusting plate 66 falls back to the preset position, and the opening of the air outlet 3 is reduced to 30%-50%. At this time, the residence time of the airflow in the sterilization and purification chamber can be extended, ensuring that the airflow fully contacts the safety sterilization and disinfection module 7 and the odor adsorption and decomposition module 8. The purification efficiency can still be maintained at low wind speed, while further reducing the fan operating noise to ≤28dB, which is suitable for the long-term continuous purification and quiet requirements of the neurology ward.

[0069] In summary, this embodiment uses an electric push rod 59 to drive multiple U-shaped frames 52 to achieve the state switching of "parallel and equidistant - superimposed and overlapping". At the same time, with the meshing transmission of the rack plate 62 and gear 63, and the threaded transmission of the threaded rod 64 and the fixed plate 65, the precise mechanical linkage of the movement of the U-shaped frame 52 and the lifting of the shielding adjustment plate 66 is achieved. Ultimately, the adaptive adjustment of "filter unit superposition → air outlet 3 opening larger, filter units parallel → air outlet 3 shrinking" is achieved, perfectly matching the air volume and air pressure requirements under high / low pollution conditions. This ensures that the device can balance purification efficiency and quiet operation under different conditions, and fully adapts to the special usage requirements of neurology wards.
