Description

[0001] The invention relates to the technical field of plasma sterilization equipment, and in particular to a modular plasma discharge device. Background Art

[0002] In the medical and health field, the environment needs to be disinfected and bacteria killed, so plasma disinfection equipment is needed. Under the action of a strong electric field, high-energy electrons collide inelastically with gas molecules and atoms to form plasma. These plasmas kill microorganisms by oxidation, breaking cell membranes, etc., while producing negative oxygen ions, OH ions and free oxygen atoms, etc., which have extremely strong bactericidal ability; in addition, plasma can also decompose toxic organic substances such as formaldehyde, benzene, and ammonia, and convert them into low-molecular non-toxic inorganic substances.

[0003] When the plasma disinfection equipment is in use, when the fan rotates to drive the airflow through the plasma plate, the flow rate at the center of the fan is greater than the flow rate around it, which makes the wind speeds in different areas of the plasma plate different. The different wind speeds lead to different gas concentrations, which can easily cause the equipment to trigger a high temperature alarm, and filter before disinfection. After long-term use, dust accumulates on the surface of the filter plate, causing the gas flow rate to gradually weaken. The existing air inlet baffles are generally fixed. When the wind speed gradually decreases, the fixed baffles will also cause different flow rates in different areas, increase the high temperature generated by the plasma plate, and reduce the service life of the equipment.

[0044] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0045] See also Figure 1-Figure 10The present embodiment provides a modular plasma discharge device, including a box body 1, wherein the box body 1 includes a disinfection device, wherein the disinfection device is provided with a filter plate 21, a fan 22, and a plasma plate 23 in sequence from front to back, wherein the plasma plate 23 is provided with rounded corners around to avoid the tip discharge from reducing the service life of the plasma plate 23, and at the same time avoid the local temperature from being too high, and an ozone remover 24, wherein the ozone remover 24 decomposes and transforms the ozone generated by the plasma plate 23 during the discharge disinfection to avoid the generation of radiation; and further includes a plurality of wind plates 3 to form a plurality of air inlet channels, wherein a counterweight block is installed at the bottom center of the wind plate 3, When no gas passes through, the wind plate 3 maintains a horizontal state. The wind plate 3 is rotatably arranged on the inner wall of the box body 1 through the rotating shaft 31. The wind plate 3 is arranged in a rotating manner. The angle of the wind plate 3 is adjusted according to the flow rate of the gas so that the wind speed flows evenly through the plasma plate 23 to avoid equal gas concentration at different positions on the plasma plate 23; it also includes a locking member, which is used to lock the rotation of the wind plate 3. Two locking members are arranged on one wind plate 3, and the two locking members are located at the rotating shaft 31 on both sides of the wind plate 3; it also includes a movable plate 4. When ventilating, the movable plate 4 drives the locking member to unlock, so that the wind plate 3 can adaptively adjust the angle according to the gas flow rate.

[0046] In an embodiment further provided by the present invention, a connecting part is also included, which drives the locking part to move through the connecting part so that the unlocking part unlocks the wind plate 3. The inner side wall of the box body 1 is fixedly connected with a protective cover 11, and the connecting part and the locking part are both arranged in the protective cover 11 to reduce the influence of gas flow on the connecting part and the locking part.

[0047] In an embodiment further provided by the present invention, after the wind plate 3 is rotated by adaptive adjustment, the angle between the movable plate 4 and the wind plate 3 increases to reduce the gas flow, and the movable plate 4 moves downward so that the locking member passively locks the wind plate 3.

[0048] In the embodiment provided by the present invention, a fixed plate 5 is further included, on which a movable plate 4 is rotatably arranged, and the fixed plate 5 is fixed to the inner wall of the box body 1. Cloths are fixedly arranged on both sides of the movable plate 4, and the cloths are fixedly connected to the fixed plate 5. The cloths are used to seal the movable plate 4 and the fixed plate 5, so that gas entering between the movable plate 4 and the fixed plate 5 can push the movable plate 4 to rotate, and the fixed plate 5 and the movable plate 4 are both arranged to be inclined surfaces. When the gas enters between the movable plate 4 and the fixed plate 5, it will reflux and then enter the plasma plate 23. When refluxing, it can absorb part of the heat to accelerate the generation and reaction speed of plasma, thereby speeding up the disinfection process and improving the disinfection efficiency. At the same time, the gas reflux can slow down the flow rate of the gas to avoid excessive gas concentration.

[0049] In the solution further provided by the present invention, the locking member includes a friction plate 61 rotatably arranged on the inner wall of the box body 1, the friction plate 61 is abutted against the rotating shaft 31 through a locking rod 62, the locking rod 62 is slidably arranged on the inner wall of the box body 1, and the locking rod 62 is fixedly connected to the limit plate 63 outside, and an abutment spring 64 is arranged outside the locking rod 62, and the two ends of the abutment spring 64 are respectively fixedly connected to the box body 1 and the limit plate 63.

[0050] In the present invention, the connecting part includes a first connecting member and a second connecting member, the first connecting member includes a support plate 71 slidably set on the movable plate 4, a connecting plate 72 is fixedly connected to the support plate 71, a telescopic plate 73 is rotatably connected to the inner wall of the box body 1, one end of the telescopic plate 73 is rotatably connected to the locking rod 62, and the other end of the telescopic plate 73 is in movably contact with the connecting plate 72.

[0051] Furthermore, a fixing rod 74 is fixedly connected to the inner wall of the box body 1, and the fixing rod 74 is slidably set in the support plate 71. By setting the fixing plate 5, when the movable plate 4 rotates, the support plate 71 only slides up and down, and no lateral movement occurs, thereby improving the stability of the support plate 71 sliding up and down.

[0052] Preferably, when the wind force gradually weakens, the second connecting member unlocks the locking member so that the rotation angle of the wind plate 3 gradually slows down. The second connecting member includes a guide plate 81 fixed to the inner wall of the box body 1, and a guide rod 82 is slidably arranged in the guide plate 81. The end of the guide rod 82 is fixedly connected to a wedge plate 83, and the wedge plate 83 is in movable contact with the telescopic rod. A tension spring 84 is provided on the outer sleeve of the guide rod 82, and the two ends of the tension spring 84 are respectively fixedly connected to the guide plate 81 and the wedge plate 83.

[0053] Furthermore, a guide groove 85 is provided on the wedge plate 83, and a one-way plate 86 is rotatably arranged in the guide groove 85. A limit rod 87 slidably arranged in the guide groove 85 is fixedly connected to the support plate 71. There are multiple limit rods 87. The guide groove 85 is composed of an inclined groove and a straight groove. One end of the one-way plate 86 is overlapped on the inclined groove. When the support plate 71 moves downward to drive the limit rod 87 to move, since the one-way plate 86 only rotates upward, when the limit rod 87 moves downward, the inclined groove moves in the limit rod 87, causing the wedge plate 83 to be laterally displaced. When the limit rod 87 moves out of the inclined groove, the tension spring 84 will pull the wedge plate 83 to reset. When the limit rod 87 moves upward, the limit rod 87 moves in the straight groove and will not drive the displacement of the wedge plate 83.

[0054] In the present invention, a torsion spring 41 is disposed on the outer sleeve of the movable plate 4 , and two ends of the torsion spring 41 are respectively fixedly connected to the fixed plate 5 and the movable plate 4 .

[0055] When in use: the fan 22 and the plasma panel 23 are connected to an external power supply, and air is blown into the box 1 through the fan 22, and first filtered through the filter plate 21, and the filtered gas enters the plasma panel 23 through the air plate 3, and the plasma panel 23 is energized to disinfect the passing gas;

[0056] At the beginning of use, when the gas flow enters the device, the gas enters between the movable plate 4 and the fixed plate 5, thereby pushing the movable plate 4 to rotate. The movable plate 4 rotates and pushes the support plate 71 to move upward, so that the connecting plate 72 pushes the telescopic plate 73 to rotate, and pulls the locking rod 62 to move downward, thereby moving out the friction plate 61, and the movable plate 4 is pushed to rotate by the gas flow. When the wind speeds above and below the movable plate 4 are consistent, the movable plate 4 stops rotating. At the same time, the flow rate below the movable plate 4 decreases, so that the movable plate 4 is rotated downward by the torsion spring 41, so that the connecting plate 72 moves downward, and the locking rod 62 is pushed upward by the abutment spring 64, and the friction force is pressed against the rotating shaft 31 to lock the movable plate 4.

[0057] Since the filter plate 21 will filter impurities in the gas, after long-term use, impurities will adhere to the surface of the filter plate 21, affecting the flow of the gas, causing the gas flow rate to gradually weaken. When the flow rate decreases, the gas entering the movable plate 4 is reduced, so that the angle between the movable plate 4 and the fixed plate 5 is reduced, so that the support plate 71 moves downward, driving the limit rod 87 to move downward, thereby pushing the wedge plate 83 to move toward the telescopic plate 73, pushing the telescopic plate 73 downward, so that the locking rod 62 moves out of the friction plate 61, and the angle of the wind plate 3 is adjusted according to the flow of wind speed. After the limit rod 87 moves out of the wedge plate 83, the locking rod continues to press against the friction plate;

[0058] When the flow rate continues to weaken, similarly, the limit rod 86 located at the top moves into the wedge plate 83 to continue to adjust the angle of the wind plate. When the equipment is turned off, the upper limit rod 87 moves out of the wedge plate 83, and the wind plate 3 is rotated to a horizontal state through the counterweight block of the wind plate 3. When the limit rod 87 moves out of the guide groove 85, the wedge plate 83 is pulled to reset through the tension spring 84.

[0059] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
