Description

Technical Field

[0001] The invention relates to the field of air purification, and in particular to an air purification and disinfection machine. Background Art

[0002] Air purification equipment is a special equipment used to purify various pollutants in indoor air, such as PM2.5, dust, odor, decoration pollutants, bacteria, etc. Existing air purification equipment is divided into two types: filter type and electric purification type; among them, filter type air purification equipment relies on a variety of filter elements to filter out particulate pollutants in the air. In order to improve the sterilization effect of filter type air purification equipment, there are purifiers in the prior art that add ultraviolet lamps inside the equipment. Ultraviolet rays can destroy the DNA or RNA molecular structure in the cells of microorganisms, causing productive cell death and / or regenerative cell death, and have a good sterilization effect on natural air bacteria and Staphylococcus aureus.

[0003] However, ultraviolet radiation is harmful to human eyes and skin. In the prior art, there are two installation positions for ultraviolet lamps: installed on the upstream side or downstream side of the filter element inside the device; when installed on the upstream side of the filter element, the risk of ultraviolet radiation spillage is low, but the air is first sterilized by ultraviolet rays and then physically filtered through the filter element. If the filter element is not replaced for a long time, it is easy to carry out the bacteria that grow in the filter element; when installed on the downstream side of the filter element, the ultraviolet lamp is close to the air outlet of the air purification device, and the risk of ultraviolet radiation spillage is relatively large. In addition, the existing air purification equipment containing ultraviolet sterilization generally reminds users in the instruction manual: once ultraviolet rays that can be seen directly without passing through any object are found during normal use, they should be stopped and repaired; this has led to users always doubting the safety of its use, resulting in relatively low user acceptance of air purification equipment containing ultraviolet sterilization. Summary of the invention

[0004] The present invention provides an air purification and disinfection machine, one of the technical problems solved is that when the ultraviolet lamp is close to the air outlet of the air purification equipment, the risk of ultraviolet radiation spillage is relatively large, so as to achieve the purposes of reducing the risk of ultraviolet radiation spillage and improving the safety of use.

[0005] The present invention is achieved through the following technical solutions:

[0006] An air purifying and disinfecting machine comprises a machine body, a cover plate located on the top of the machine body, an ultraviolet lamp located inside the machine body, and an air outlet located on the cover plate, wherein a coaxial annular inner slide groove and an annular outer slide groove are provided on the top surface of the cover plate, the air outlet is located inside the annular inner slide groove, and the annular inner slide groove is located inside the annular outer slide groove;

[0007] It also includes an inner arc plate that is slidably fitted on the annular inner slide groove, an outer arc plate that is slidably fitted on the annular outer slide groove, and a shielding plate located above the inner arc plate and the outer arc plate, and the shielding plate is detachably connected to the cover plate.

[0008] In view of the problem in the prior art that when the ultraviolet lamp is close to the air outlet of the air purification equipment, the risk of ultraviolet radiation leakage is relatively large, the present invention proposes an air purification and disinfection machine, wherein the ultraviolet lamp is arranged inside the machine body, a cover plate is arranged on the top of the machine body, and an air outlet is opened on the cover plate, etc., which are all prior art. The present application opens two annular slide grooves distributed inside and outside on the cover plate, which are respectively defined as an inner annular slide groove and an outer annular slide groove, and the inner annular slide groove is located outside the air outlet, and the outer annular slide groove is located outside the inner annular groove. The inner arc plate matches the inner annular slide groove and can slide in the inner annular slide groove, and the outer arc plate matches the outer annular slide groove and can slide in the outer annular slide groove. The present application is also provided with a shielding plate detachably connected to the cover plate, and the shielding plate is located above the inner arc plate and the outer arc plate.

[0009] It can be seen that the present application uses the inner arc plate and the outer arc plate to shield the area around the air outlet, and uses the shielding plate to shield the top of the air outlet. If a malfunction or damage occurs inside the machine body, causing ultraviolet rays to leak out from the air outlet, the inner arc plate and the outer arc plate can block most of the ultraviolet rays, thereby reducing the risk of ultraviolet light waves escaping into the external environment; and the ultraviolet light waves are constantly reflected between the inner arc plate, the outer arc plate and the shielding plate, which can consume a lot of their energy and further reduce the harm to the human body; by protecting and shielding the air outlet, the user's doubts about the safety of air purification and disinfection machines containing ultraviolet sterilization can be effectively reduced, and the user's acceptance of such equipment can be improved; and the built-in ultraviolet lamp tube of the present application can be installed on the downstream side of the filter element, which is more conducive to ensuring the sterilization effect. In addition, when the present application is working, the specific air outlet direction and the size of the air outlet area can be adjusted by adjusting the specific positions of the inner arc plate and the outer arc plate. Compared with the prior art method of adjusting the direction of the air outlet fan blades, the adjustability is higher, and the air outlet direction can be truly adjusted 360°, and the size of the air outlet area can also be adjusted.

[0010] Furthermore, the sum of the central angle of the inner arc plate and the central angle of the outer arc plate is greater than 360°, so as to ensure that the inner arc plate and the outer arc plate always have a partially overlapping area, ensuring that the air outlet can be completely blocked in all directions when the present application is not needed.

[0011] The inner arc plate and the outer arc plate have the same height, and the distance between the top of the inner arc plate and the outer arc plate and the bottom surface of the shielding plate is less than or equal to 2 mm. This solution makes the gap between the inner arc plate, the outer arc plate and the shielding plate small enough to reduce the air that escapes from the gap and ensure that the purified air is discharged from the gap between the inner arc plate and the outer arc plate. Preferably, the top of the inner arc plate and the outer arc plate directly abuts against the bottom surface of the shielding plate.

[0012] Furthermore, the baffle plate is a circle coaxial with the annular inner slide groove and the annular outer slide groove; it also includes a plurality of annular evenly distributed positioning holes opened on the top surface of the cover plate, and a plurality of annular evenly distributed positioning columns fixedly connected to the bottom of the baffle plate, and the positioning holes correspond to the positioning columns one by one and match each other; the inner walls of the positioning holes, the annular inner slide groove, and the annular outer slide groove are all provided with vibration-damping pads.

[0013] In this solution, by inserting each positioning column into the corresponding positioning hole, a detachable connection between the shielding plate and the cover plate is achieved, so that the shielding plate can be quickly removed when it is not needed. In addition, in this solution, the air discharged from the inside of the machine body blows upward to act on the shielding plate, and then spreads to the surroundings to act on the inner arc plate and the outer arc plate, which easily causes the shielding plate, the inner arc plate, and the outer arc plate to shake in the corresponding grooves. In this solution, vibration-damping pads are arranged on the inner walls of the positioning holes, the annular inner slide groove, and the annular outer slide groove, so that each positioning column, as well as the bottom ends of the inner arc plate and the outer arc plate are in contact with the corresponding vibration-damping pads and not directly in contact with the groove wall, thereby eliminating the noise interference caused by the disturbance of the airflow.

[0014] Furthermore, the inner arc plate, outer arc plate and shielding plate are all made of anti-UV glass, so that when ultraviolet light overflows from the air outlet to the outside of the body, the anti-UV glass can further enhance the blocking effect of escaping ultraviolet light, while helping the body maintain a good aesthetic level.

[0015] Flexible parts are provided at both circumferential ends of the inner arc plate, and the thickness of the flexible parts gradually decreases from the middle to both ends along the circumferential direction, and the maximum thickness of the flexible parts is greater than the difference between the outer diameter of the inner arc plate and the inner diameter of the outer arc plate. In this scheme, in order to avoid friction and scratches between the outer wall of the inner arc plate and the inner wall of the outer arc plate, a certain gap is provided between the inner arc plate and the outer arc plate in the radial direction, and the exhausted air will be partially discharged from the gap, which is not conducive to the overall control of the air outlet direction. To this end, this scheme also provides flexible parts at both circumferential ends of the inner arc plate. Along the circumferential direction, the flexible parts are thin at both ends and thick in the middle, and the thickness of the thickest part is greater than the aforementioned gap. Then, when one end of the inner arc plate rotates relatively to the inner area of ​​the outer arc plate, the thinner end of the flexible part first enters the aforementioned gap, and then gradually squeezes the flexible part until the flexible part is compressed in the aforementioned gap. This arrangement can not only block the gap and reduce the risk of air being discharged from the gap, but also can firmly abut between the inner arc plate and the outer arc plate through the compressed flexible part, thereby improving the stability of the inner arc plate and the outer arc plate in the radial direction and further reducing the probability of the inner arc plate and the outer arc plate shaking or even making noise in the radial direction.

[0016] Furthermore, the body has detachable side panels on opposite sides, and a plurality of air inlet holes are provided on the side panels; it also includes a fixing plate fixed inside the body, and a fan installed on the fixing plate, and the exhaust end of the fan is connected to the inlet end of the air outlet.

[0017] This solution adopts a structure that allows air to enter both sides of the machine body at the same time, and the fan draws air from both sides of the machine body and discharges it upward. The fixing plate is fixed to the inner wall of the machine body to provide a stable installation position for the fan.

[0018] Furthermore, two positioning plates are connected to the bottom surface of the fixing plate, the positioning plates are parallel to the side plates, and the two positioning plates are respectively located on both sides of the fan; a lamp holder is provided on the surface of the positioning plate facing the direction of the fan, and the ultraviolet lamp is installed on the lamp holder.

[0019] This solution connects two mutually parallel positioning plates under the fixed plate. The two positioning plates face the side plates on both sides respectively. The area between the positioning plates and the side plates on the same side is used to install the filter assembly. The positioning plates provide an installation position for the lamp holder. It can be seen that this solution installs the ultraviolet lamp tube on the positioning plates on both sides and its installation direction faces inward, which can disinfect and sterilize the air after physical filtration. At the same time, due to the presence of a fixed plate above the ultraviolet lamp tube, the ultraviolet rays can be effectively blocked inside the machine body. Under non-fault conditions, it is difficult for ultraviolet rays to spread from the air outlet to the outside of the machine body, so that users cannot observe ultraviolet rays with the naked eye under normal conditions.

[0020] Furthermore, it also includes a partition fixed on the bottom surface of the body, the partition is parallel to the side panel, and the partition divides the lower area of ​​the body into a first area and a second area; it also includes a baffle hinged on the top of the partition and a driving device for driving the baffle to rotate, and the baffle can independently cover the first area and the second area at the top when driven by the driving device.

[0021] In the prior art, many air purifiers and disinfectors are equipped with side panels and air inlets on both sides of the machine body. This arrangement is to improve the air intake efficiency and to facilitate users to place it in different positions and orientations for use. However, the inventors of this case found in the research process that this type of prior art has the following disadvantages: many users need to place the machine body against the wall in the corner of the room. This double-sided air intake structure causes one side of the air intake hole to be too close to the wall, which is easy to produce a large airflow sound when the wind is strong, that is, the wind noise is large. In the prior art, the silent design of air purification equipment is mostly focused on the silence inside the machine body, and there is rarely any research on reducing the wind noise between the machine body and the external wall.

[0022] In order to overcome this problem, this solution sets a partition on the bottom surface of the body while maintaining the traditional double-sided air intake structure. Since the partition is parallel to the side panel, the partition divides the lower area of ​​the body into a first area and a second area, and the first area and the second area are respectively connected to the air intake holes on the side panels on both sides. The baffle is hinged at the top of the baffle and driven to rotate by the driving mechanism. The baffle can block the top of the first area alone, can also block the top of the second area alone, and can also keep the first area and the second area connected to the air intake end of the fan above.

[0023] When this solution is used specifically: if both side panels are not placed against the wall and there is no need to worry about the wind noise, the baffle can be rotated vertically upward by the driving device. At this time, the first area and the second area are both connected to the air inlet end of the fan above, and the fan can draw air from the outside through the air inlet holes on the side panels on both sides; if any side panel is placed against the wall and the wind noise on that side is relatively large, the baffle can be driven by the driving device to rotate to a position that blocks the top of the first area or the second area corresponding to that side. At this time, the fan can only draw external air from the air inlet holes on the other side panel away from the wall, and there will be no high-speed airflow at the side panel against the wall, so there will be no large airflow sound.

[0024] It can be seen that this solution solves the problem in the prior art that the machine body with double-sided air intake is prone to generate large wind noise when placed against a wall or at a corner, and the solution maintains the use of only one fan, which is more conducive to controlling production costs compared to the solution of independently setting up fans for air inlets on different sides.

[0025] Furthermore, a first arc-shaped groove is provided on the surface of one side of the positioning plate facing the direction of the fan, and a step surface is provided at the bottom end of the first arc-shaped groove; the bottom surface of the fixing plate is connected to the mounting bracket located below the fan, and a second arc-shaped groove is provided on the bottom surface of the mounting bracket; the end of the baffle away from the direction where the partition is located can enter the first arc-shaped groove and the second arc-shaped groove, and the axes of the first arc-shaped groove and the second arc-shaped groove are colinear with the rotation axis of the baffle; it also includes a first magnet arranged at the end of the baffle away from the direction where the partition is located, a second magnet arranged at the bottom of the first arc-shaped groove, and a third magnet arranged at the bottom of the second arc-shaped groove, and the first magnet is magnetically attracted to the second magnet and the third magnet.

[0026] This solution defines the specific rotation and limiting structure of the baffle. The first arc-shaped groove is provided on the side surface of any one positioning plate in the direction of the other positioning plate. The top of the first arc-shaped groove extends to the surface of the positioning plate, and a step surface is provided at the bottom end thereof for positioning the rotation of the baffle. The mounting frame is connected to the bottom surface of the fixed plate, and the mounting frame is located below the fan. It is a frame structure and will not affect the normal entry of air into the fan. A second arc-shaped groove is provided on the bottom surface of the mounting frame, wherein the axes of the first arc-shaped groove and the second arc-shaped groove are colinear with the rotation axis of the baffle, that is, the first arc-shaped groove and the second arc-shaped groove are both located on the rotation trajectory of the end of the baffle, so that the end of the baffle can enter the first arc-shaped groove and the second arc-shaped groove.

[0027] In this solution, if the side panels on both sides are not placed against the wall and there is no need to worry about the wind noise, the baffle is rotated vertically upward by the driving device, and the baffle enters the second arc groove; if any side panel is placed against the wall and the wind noise on that side is large, the baffle is driven by the driving device to rotate from top to bottom to the first arc groove that blocks that side and abuts against the corresponding step surface. Considering the need to maintain the stability of the baffle state, and because the end of the baffle is a certain distance away from the output end of the driving device, it may shake under the action of the airflow, and even collide with the groove wall to produce noise, so this solution also sets a first magnet at the end of the baffle, a second magnet at the bottom of the first arc groove, and a third magnet at the bottom of the second arc groove, so that after the baffle enters the corresponding arc groove, it can maintain temporary stability through magnetic adsorption to avoid shaking and noise at the end of the baffle. Of course, when the baffle position needs to be adjusted again, the output power of the driving device can overcome the magnetic attraction. It should be noted that the groove bottom of the first arc-shaped groove and the second arc-shaped groove refers to the groove wall on one side away from the open end of the groove.

[0028] Furthermore, it also includes a filter assembly connected to the inner wall of the side plate; when the side plate is connected to the body, the filter assembly abuts against the positioning plate on the same side.

[0029] In the prior art, the filter assembly is generally installed inside the machine body, and the side panel needs to be opened before the filter assembly can be removed for cleaning or replacement. However, the present solution integrates the filter assembly on the side panel, and the filter assembly can be removed at the same time by removing the side panel, which significantly reduces the difficulty for users to remove the filter assembly for cleaning or replacement. At the same time, the positioning plates on both sides respectively position the filter assemblies on both sides, which is convenient for users to install the filter assembly, and also facilitates the airflow to flow more concentratedly to the first area and / or the second area. Among them, the filter assembly can preferably be implemented using a multi-layer filter screen or a composite filter screen structure in the prior art.

[0030] Furthermore, the filter assembly includes a frame with closed bottom and top surfaces, and the frame is provided with installation channels on two opposite side surfaces perpendicular to the side plates. It also includes a pressure plate that slides in the installation channel in a direction perpendicular to the side plate surface, and a plurality of elastic parts are connected between the pressure plate and a groove wall on one side of the installation channel close to the side plate surface.

[0031] This solution uses a frame to achieve the effect of integrating the filter assembly on the side panel. The frame is directly connected to the side panel, and the filter element or filter screen used for filtering is installed in the frame. The bottom and top of the frame are closed, forcing the airflow entering the body from the air inlet to flow forward to the corresponding first area or second area. Installation channels are opened on the lateral sides of the frame for installing the two ends of the filter element or filter screen, and the two ends are pressed and fastened by the pressure plates at both ends, and the pressing and fastening force is provided by a number of elastic parts. It can be seen that this solution can simultaneously meet the disassembly, cleaning and replacement of the integrated filter element as a whole, and can also meet the disassembly, cleaning and replacement of the multi-layer composite filter screen piece by piece or as a whole. It has excellent versatility and improves the adaptability of the air purification and disinfection machine to the internal filter screen or filter element.

[0032] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0033] 1. In an air purifier and disinfector of the present invention, if a malfunction or damage occurs inside the machine body causing ultraviolet rays to escape from the air outlet, most of the ultraviolet rays can be blocked by the inner arc plate and the outer arc plate, thereby reducing the risk of ultraviolet light waves escaping into the external environment.

[0034] 2. The air purification and disinfection machine of the present invention can adjust the specific positions of the inner arc plate and the outer arc plate to control the specific air outlet direction and the size of the air outlet area during operation. Compared with the prior art method of adjusting the direction of the air outlet fan blades, the air purification and disinfection machine has higher adjustability, can achieve true 360° adjustment of the air outlet direction, and can also achieve adjustment of the size of the air outlet area.

[0035] 3. The air purification and disinfection machine of the present invention can reduce the probability of the inner arc plate and the outer arc plate shaking or even making noise in the radial direction.

[0036] 4. The present invention provides an air purifier and disinfector, in which ultraviolet lamps are installed on positioning plates on both sides and the installation direction thereof faces inwards, so that the air after physical filtration can be disinfected and sterilized. At the same time, due to the presence of a fixing plate above the ultraviolet lamp, the ultraviolet rays can be effectively blocked inside the machine body, and under non-fault conditions, it is difficult for the ultraviolet rays to escape from the air outlet to the outside of the machine body, so that the user cannot observe the ultraviolet rays with the naked eye under normal circumstances.

[0037] 5. An air purification and disinfection machine of the present invention solves the problem in the prior art that the machine body with double-sided air intake is prone to generate large wind noise when placed against a wall or at a corner, and the solution maintains the use of only one fan, which is more conducive to controlling production costs compared to the solution of independently setting fans for air inlets on different sides.

[0038] 6. In an air purification and disinfection machine of the present invention, after the baffle enters the corresponding arc groove, the baffle is temporarily stabilized by magnetic adsorption to prevent the end of the baffle from shaking and generating noise.

[0039] 7. An air purifier and disinfector of the present invention integrates a filter assembly on a side panel. The filter assembly can be removed simultaneously by removing the side panel, which significantly reduces the difficulty for users to disassemble the filter assembly for cleaning or replacement. It can also meet the needs of disassembly, cleaning and replacement of the integrated filter element as a whole, and can also meet the needs of disassembly, cleaning and replacement of multi-layer composite filter screens piece by piece or as a whole. It has excellent versatility and improves the adaptability of the air purifier and disinfector to the internal filter screen or filter element. BRIEF DESCRIPTION OF THE DRAWINGS

[0072] In this embodiment, the partition plate 20 and the baffle plate 23 are as follows: Figure 4 The depths shown match the internal dimensions of the body 1 to ensure effective separation and blocking of the interior of the body.

[0073] The driving device 24 preferably uses a servo motor to facilitate controlling the rotation angle of the baffle 23; in addition, a sensing device for sensing the end of the baffle 23, such as a contact switch, a distance sensor, a pressure sensor, etc., can be set in the first arc groove 25 and the second arc groove 28.

[0074] When this embodiment is used specifically: if the side panels on both sides are not placed against the wall and there is no need to worry about the wind noise, the baffle can be rotated to a vertical position by the driving device, at which time the end of the baffle enters the second arc groove 28, the driving device 24 is locked, and the first magnet 29 is attracted to the third magnet 31.

[0076] Embodiment 3:

[0077] An air purification and disinfection machine, based on embodiment 2, as Figure 1 and Figure 8 As shown, it also includes a filter assembly 32 connected to the inner wall of the side plate 14; when the side plate 14 is connected to the body 1, the filter assembly 32 abuts against the positioning plate 18 on the same side.

[0078] The filter assembly 32 includes a frame 321 with closed bottom and top surfaces, and a filter element installed in the frame 321. The frame 321 is provided with installation channels 322 on two opposite side surfaces perpendicular to the side plate 14, and also includes a pressure plate 323 that slides in the installation channel 322 in a direction perpendicular to the surface of the side plate 14. A plurality of elastic members 324 are connected between the pressure plate 323 and a groove wall on one side of the installation channel 322 close to the surface of the side plate 14.

[0079] The filter element in this embodiment may be an integrated composite filter structure, or a split structure formed by overlapping multiple layers of independent filter screens.

[0080] The elastic members 324 in this embodiment are a plurality of springs that are always in a compressed state, and thus always provide a thrust to the pressure plate 323 in a direction away from the side plate 14 .

[0081] When the filter element needs to be removed, the pressing plate 323 is pushed toward the side plate 14 by manpower to further compress the elastic member 324, so that the pressing plates 323 on both sides contact and hold the filter element, and the filter element can be taken out from the installation channel 322;

[0082] When the filter element needs to be installed, the pressure plate 323 is pushed toward the side plate 14 by manpower to open the installation channel 322, and the filter element is inserted from the side. After the filter element is adjusted into position, the force on the pressure plate 323 is released, so that the pressure plates 323 on both sides can firmly hold the two ends of the filter element in the frame 321 under the action of the elastic members.

[0083] In a more preferred embodiment, a telescopic plate 325 is further connected between the pressing plate 323 and the side wall of the frame 321 close to the surface of the side plate 14, and the telescopic plate 325 is located in the outer direction of the elastic member in the horizontal direction. The telescopic stroke of the telescopic plate 325 can meet the sliding range of the pressing plate 323 in the installation channel 322, so that no matter how the pressing plate 323 slides, the telescopic plate 325 can be telescoped externally. Through the telescopic plates 325 on both sides, the frame 321 is not only closed at the bottom and top, but also can maintain relative closure on both sides in the horizontal direction regardless of the thickness of the clamped filter element, so that the airflow entering the frame 321 can only completely pass through the internal filter element and then move toward the inside of the body 1, which further ensures the full physical purification effect of the airflow.
