[0008] Furthermore, the air inlet end and the air outlet end are smoothly transitioned.

[0009] Furthermore, the air duct is circular tubular, the air outlet is oblong hole-shaped, and the axis of symmetry of the air outlet along the length direction is parallel to the axis of the air duct.

[0010] Furthermore, the air duct includes an upper pipe body and a lower pipe body, the upper pipe body and the lower pipe body are detachably connected, and the air outlet is opened on the pipe wall of the lower pipe body near the air inlet.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Embodiment 1

[0027] According to Figures 1 to 5The wind equalizing device shown includes an wind equalizing plate 17, on which a guide surface 1 for changing the direction of the airflow is provided, the guide surface 1 includes an air inlet end 9 and an air outlet end 8, the angle formed by the cross-sections of the two end surfaces of the air inlet end 9 and the air outlet end 8 is a deflection angle, and the guide surface 1 is provided with a plurality of baffles 2, the baffles 2 include a wind receiving surface 14 close to the wind source, the plurality of wind receiving surfaces 14 are parallel to each other, the plurality of baffles 2 are arranged at equal intervals in a direction perpendicular to the end surfaces of the wind receiving surfaces 14, and an air path groove is formed between two adjacent baffles 2. The guide surface 1 is one of the end surfaces on the air equalizing plate 17. During the processing of the air equalizing plate 17, a plate can be bent so that the plate forms an angle at a certain point on the plate surface, or several plates can be connected. The plate surfaces of the plates form a certain angle with each other during the connection process. The end surface of the plate facing the bending direction can be used as the guide surface 1. When the airflow flows in a direction along the guide surface 1, since there is at least one bending point on the guide surface 1, the gas hits the bent plate surface at the bending point and turns. After turning, the airflow flows along the bent plate surface, thereby realizing the turning of the airflow through the guide surface 1. In this scheme, a retaining rib 2 is provided on the guide surface 1, and an air path groove is formed between two adjacent retaining ribs 2. The air path grooves are independent of each other, and the function of the air path groove is to guide the airflow. In an optional implementation scheme, since the wind source in this scheme is a centrifugal fan 4, the fan blows the outside air into the wind balancing plate 17. Since the centrifugal fan 4 is located at a certain point of the air inlet end 9 of the wind balancing plate 17, for most of the air path grooves, the airflow blown in at the air inlet end 9 has an angle with the groove direction of the air path groove. When the airflow enters the air path groove, it first collides with the wind receiving surface 14, and then the airflow It may turn and then hit the other side end face of the adjacent retaining rib 2. During the collision, the direction of the airflow gradually becomes consistent with the direction of the wind path slot. When the final airflow flows out from the air outlet end 8, the airflow in each wind path slot is roughly consistent with the direction of the wind path slot. Since the wind receiving surface 14 that initially impacts has the greatest influence on the direction of the airflow, when the wind receiving surface 14 remains parallel, the directions of the airflows flowing out of each wind path slot are roughly parallel to each other. Due to the diffusion of the airflow, the airflows cannot be absolutely parallel. The airflow turbulence caused by a certain mutual interference is within the allowable error range of this scheme.

[0028] The function of the retaining rib 2 in the present scheme is to evenly separate the airflow generated by the wind source originally at a certain point into a number of air path grooves. The airflow in each air path groove is independently guided, and finally blown out from the air outlet 7 on the guide surface 1 as a relatively uniform airflow, thereby increasing the air path width of the airflow and the uniformity between the airflow at each point within the air path width and the airflow in other parts, thereby avoiding the situation where the airflow is blown out along a narrow beam-shaped air path, causing the local wind force of the wind-receiving object to be too strong while the other parts cannot be affected by the wind.

[0029] A number of windward surfaces 14 in this solution are parallel to each other. A number of retaining ribs 2 are arranged at equal intervals in a direction perpendicular to the end surface of the windward surface 14. The definitions of parallel and equal intervals include the allowable errors of this solution. The included angle between two adjacent windward surfaces 14 can be equivalently regarded as parallel within the range of -1° to 1°. The distance error between two adjacent retaining ribs 2 is equal to or less than 5% of the interval, and can be equivalently regarded as equal intervals.

[0030] In an alternative embodiment, the air distribution device further includes an air duct 3. The air duct 3 is cooperatively connected with the air distribution plate 17. An air outlet 7 is provided on the pipe wall of the air duct 3 near the air inlet end 9. An air inlet 18 is provided on the air duct 3, and an air source is provided at the air inlet 18. The air outlet 7 is communicated with at least a part of all the air path grooves. The function of the air duct 3 is to connect the air source and the air distribution plate 17. Since the width of the air distribution plate 17 is much larger than the size of the air outlet of the air source, the air duct 3 is needed to divert the air flow at the air source to the air inlet end 9 of the air distribution plate 17. The air flow enters the air duct 3 from the air inlet 18, flows in the pipe under the action of air pressure, and flows out from the air outlet 7 into the air inlet end 9 of the diversion surface 1 of the air distribution plate 17. At least a part of the air inlet end 9 of each air path groove is communicated with the air outlet 7. The air flow flowing out from the air outlet 7 can enter each air path groove, so that the width of the air path where the final air flow flows out from the air outlet end 8 is consistent with the interval between the two outermost retaining ribs 2. In this solution, the width of the wind-receiving area of the wind-receiving object can be adjusted by adjusting the interval between the two outermost retaining ribs 2 when the air flow blows to the wind-receiving object.

[0031] Since the width of the air distribution plate 17 is much larger than the size of the air outlet of the air source, during the process of the air flow from the air inlet 18 to the air outlet 7, a part of the air flow needs to flow horizontally in the air duct 3 to reach the air outlet 7 corresponding to the air path groove at the edge. At this time, the direction of the air flow at the air outlet 7 has a longitudinal component from the air inlet 18 to the air outlet 7 and a transverse component generated by the flow in the air duct 3. Due to the existence of the transverse component, after the air flow enters the air path groove, it impacts the windward surface 14, and through the baffle effect of the windward surface 14, the air flow direction consistent with the groove direction of the air path groove is achieved at the air outlet end 8.

[0032] For product applications that do not require changing the wind direction and have low requirements for the uniformity of the air outlet, the air distribution plate 17 can also be directly cancelled, and the air is directly discharged through the air duct 3, which can reduce the overall structural size.

[0033] In an alternative embodiment, the end face of the baffle rib 2 close to the diversion surface 1 is completely fitted to the diversion surface 1. The function of the baffle rib 2 is to form independent air passage grooves. Through the independent diversion of the air flow in each air passage groove, the air flow at the air outlet end 8 is made to be substantially parallel to the wind-receiving surface 14 in the width direction of the diversion surface 1 at the air outlet end 8. At the same time, due to the existence of the air passage grooves, the air flow can evenly pass through the diversion surface 1 and finally flow out from the air outlet end 8, so as to avoid the situation where the air flow blows laterally to the two side edges of the diversion surface 1 and the required air output cannot be formed at the air outlet end 8 near the middle of the diversion surface 1. Therefore, in this solution, the baffle rib 2 and the diversion surface 1 are completely fitted to avoid the situation where the adjacent two air passage grooves are in a connected state due to the gap at the connection between the baffle rib 2 and the diversion surface 1, and the air flow may enter the adjacent air guide grooves from the gap when hitting the wind-receiving surface 14.

[0034] In this solution, the air distribution plate 17 and the baffle rib 2 can be integrally injection-molded, or can be processed separately as plate parts. The fitting between the baffle rib 2 and the diversion surface 1 can be completed by processes such as adhesive bonding and hot melting, or can be inserted and sealed at the joint, so as to ensure the fitting tightness between the baffle rib 2 and the air distribution plate 17.

[0035] In an alternative embodiment, the air inlet end 9 and the air outlet end 8 are smoothly transitioned. The air distribution plate 17 can be formed by bending the surface of a plate part through sheet metal working, or can be formed by splicing two plate parts, with a rounded corner bending point formed at the splicing position, or the required smooth transition structure can be integrally injection-molded. Since part of the kinetic energy is lost during the impact of the air flow, and the air distribution plate 17 may vibrate during the impact, a smooth transition is adopted, and the slope of the bending part gradually increases. When the air flow changes direction, the included angle between the flow direction and the tangent of the plate surface at the bending part gradually increases. Then, during each impact, the air flow will have a small-angle impact, and the energy loss each time is small, and the resulting vibration is small. The conversion from a large-angle impact to several small-angle impacts reduces the significant reduction in the kinetic energy and the significant reduction in the flow velocity caused by the air flow being blocked by the plate part at a large included angle with the air flow direction at the bending part, as well as the situation where the plate part vibrates due to direct impact.

[0036] In an alternative embodiment, the air duct 3 is circular tubular, and the air outlet 7 is a long oval hole. The axis of symmetry of the air outlet 7 along the length direction is parallel to the axis of the air duct 3. During the process of the air flow from the air inlet 18 to the air outlet 7, a part of the air flow needs to flow axially in the air duct 3. During the flow, it is affected by the negative pressure at the air outlet 7, generating a radial flow, gradually approaching the air outlet 7, and finally flowing out from the air outlet 7. Another part is affected by the negative pressure at the air outlet 7 in the radial direction of the air inlet 18 and directly moves radially to flow out from the air outlet 7. The direction of the first part of the air flow at the air outlet 7 has a radial component from the air inlet 18 to the air outlet 7 and an axial component generated by the axial flow in the air duct 3. Due to the existence of the axial component, after the air flow enters the air passage groove, it impacts the wind-receiving surface 14, and through the flow deflection effect of the wind-receiving surface 14, the air flow direction consistent with the groove direction of the air passage groove is achieved at the air outlet end 8.

[0037] Since the air duct 3 is circular tubular, the air inlet 18 for connecting the centrifugal fan 4 is located at a certain section of the air duct 3 along the axial direction. At this time, the end face of the retaining rib 2 facing the air inlet 18 is the wind-receiving surface 14.

[0038] In an alternative embodiment, the air duct 3 includes an upper pipe body 5 and a lower pipe body 6. The upper pipe body 5 and the lower pipe body 6 are detachably connected, and the air outlet 7 is formed on the pipe wall of the lower pipe body 6 near the air inlet 18. The air duct 3 is cut along the plane where the axis is located to form the upper pipe body 5 and the lower pipe body 6. The upper pipe body 5 and the lower pipe body 6 are separately molded by die-casting. Therefore, taking the plane where the axis is located as the fitting surface between the upper pipe body 5 and the lower pipe body 6 is beneficial to reducing the tolerance requirements during molding and at the same time reducing the die-casting difficulty. The upper pipe body 5 and the lower pipe body 6 are connected by snap fasteners.

[0039] In an alternative embodiment, support plates 10 for cooperating with the air duct 3 are respectively provided at both ends of the air distribution plate 17 along the direction perpendicular to the end face of the wind-receiving surface 14. First screw holes 11 for engaging fixing screws are provided on the support plates 10. The axis of the first screw holes 11 is perpendicular to the end face of the wind-receiving surface 14. Second screw holes 19 for engaging fixing screws are provided at corresponding positions of the air duct 3. The air duct 3 and the air distribution plate 17 are clamped by the support plates 10 to achieve axial positioning, and then connected by fixing screws. The circumferential fixation between the support plates 10 and the ends of the air duct 3 is only through friction. In this solution, the air duct 3 rotates around the axes of the first screw holes 11 and the second screw holes 19 to adjust the relative angular relationship between the air outlet 7 on the air duct 3 and the air distribution plate 17. Since the wind-receiving object in this solution mainly relies on receiving the air flow blown out from the air outlet end 8 on the guiding surface 1, and there is a window structure for passing through this air flow in this solution, the directional relationship between the guiding surface 1 and the window structure can be used to adjust the wind force. By rotating the air duct 3, after reaching a certain angle, the fixing screws are tightened to keep the air duct 3 stable. At this time, a part of the air flow at the air outlet 7 blows onto the guiding surface 1, so as to realize the diversion of the air flow and finally blow out from the window structure. Another part of the air flow cannot blow onto the guiding surface 1 due to the angle, and the air flow enters the cavity for accommodating this air distribution device in this solution. Under the action of other wind-blocking structures or pressure relief holes in the cavity, this part of the air flow is finally dissipated and not effectively utilized. In this solution, the rotation of the air duct 3 is used to adjust the matching angle between the air outlet 7 and the guiding surface 1 to achieve the effect of adjusting the air flow rate at the air outlet end 8.

[0040] The perpendicularity of the axis of the screw hole to the end face of the wind-receiving surface 14 ensures that during the rotation of the air duct 3, the relative positions and angles between the air outlets 7 on the air duct 3 and the respective air passage grooves are consistent, avoiding that during the rotation of the air duct 3 due to the angle between the rotating shaft and the wind-receiving surface 14, the impact angle of the air flow blown out from a part of the air outlets 7 with the wind-receiving surface 14 is a, and the impact angle of the air flow blown out from another part of the air outlets 7 with the wind-receiving surface 14 is b. The different values of a and b result in different flow directions of the air flow blown out from the air outlet ends 8 of different air passage grooves and mutual interference, causing air flow disorder.

[0041] The air duct 3 in this solution can be driven by a motor to control its rotation around the first screw holes 11 and the second screw holes 19, and fixed by locking the motor to change the air volume at the final wind-receiving object.

[0042] In an alternative embodiment, a heating device is provided inside the air duct 3. The heating device is a heating wire. A hole for passing the heating wire is provided in the upper pipe body 5 of the air duct 3. The heating wire is arranged along the axial direction of the air duct 3 and is fixed to the inner wall of the air duct 3 with heat-resistant glue for heating the air flow inside the air duct 3 to increase the drying effect of the air flow blown out from the air outlet end 8 on the object being dried. The heating wire can be strip-shaped and attached to the inner wall of the upper pipe body 5, so that during the assembly process, the wire of the heating device can first pass through the corresponding hole in the upper pipe body 5, then the heating wire is attached to the inner wall of the upper pipe body 5, and finally the upper pipe body 5 is buckled with the lower pipe body 6. To increase the heating efficiency and uniformity of the air flow inside the air duct 3, the heating wire can be spirally wound. The winding radius is the same as the inner diameter of the air duct 3, and the axial length is less than the axial dimension of the air duct 3. The heating wire is placed into the cavity of the upper pipe body 5 in a manner that fits with the upper pipe body 5, and a part of it is attached to the inner wall of the upper pipe body 5. Since the heating wire is spiral, the part that does not fit with the upper pipe body 5 just fits with the inner wall of the lower pipe body 6 when the upper pipe body 5 and the lower pipe body 6 are buckled.

[0043] On the other hand, a disinfection knife holder includes a base, and an air distribution device is provided inside the base. This air distribution structure can also be applied to products with requirements for uniform air inlet and outlet, such as air purifiers and dehumidifiers.

[0044] In an alternative embodiment, a plurality of gratings 15 for the air flow to pass through are provided on the side end face of the base near the air outlet end 8. A bottom plate 16 is provided at the position below the gratings 15 on the side end face of the base. The bottom plate 16 includes a fixed end connected to the base and a free end inclined upward, and the slope from the free end to the fixed end gradually decreases. Since the air outlet end 8 faces the long circular hole, it is necessary to set the deflection angle formed by the cross-sections of the two end faces of the air inlet end 9 and the air outlet end 8. In this solution, the long circular hole needs to be close to the bottom plate 16. During actual use, a chopping board is vertically placed on the bottom plate 16. Since the drying principle of this disinfection knife holder is to blow the air flow onto the chopping board, the air flow impacts the chopping board to generate a deflected flow. Part of the air flow flows along the surface of the chopping board and takes away the moisture on the surface of the chopping board during the flow process to achieve the drying purpose. Since the chopping board is vertically placed on the bottom plate 16, the moisture on the chopping board will drip downward or flow along the surface to the contact position between the bottom of the chopping board and the bottom plate 16. This place is prone to mildew because it is in a waterlogged state for a long time. In this solution, the long circular hole is close to the bottom plate 16, so that the blown air flow can first impact the contact position between the bottom plate 16 and the chopping board, where the wind force is the greatest, so it is convenient to dry the large amount of moisture accumulated here.

[0045] Since the long circular hole is close to the bottom plate 16, and the air distribution device in this solution is located on the extended plate body of the bottom plate 16 inside the base, the cross-section of the end face at the air outlet end 8 is set to be horizontal. The air flow blown out from the air outlet end 8 horizontally passes through the long circular hole and finally blows to the contact position between the bottom plate 16 and the chopping board.

[0046] Example 2

[0047] In an alternative embodiment, there are engaging teeth 12 for circumferentially fixing the air duct 3 provided near the support plate 10 of the air distribution plate 17, and a card slot 20 for cooperating with the engaging teeth 12 is provided at the corresponding position of the air duct 3. The cooperation between the card slot 20 and the engaging teeth 12 plays a circumferential constraint role on the air duct 3. The engaging teeth 12 are close to the support plate 10 and are provided on the retaining ribs 2 at both ends of the edge. A bracket 13 that fits against the outer wall of the lower pipe body 6 is provided on the retaining rib 2 close to the upper edge of the air duct 3. The engaging teeth 12 are provided in the middle of the bracket 13, and a card slot 20 is provided on the pipe wall at the fitting position of the lower pipe body 6 and the bracket 13. The card slot 20 is recessed in the pipe wall. When the lower pipe body 6 is placed on the bracket 13, the engaging teeth 12 just fit into the card slot 20, so that the relative position between the air duct 3 and the air distribution plate 17 and the relative angle between the air outlet 7 and the air distribution plate 17 are kept fixed. In this solution, the air volume at the air outlet end 8 is adjusted by changing the rotational speed of the centrifugal fan 4.
