Description

Technical Field

[0001] This application relates to the technical field of atomization devices, and particularly to a spraying device. Background Art

[0002] Pathogens are microorganisms, parasites, or other agents that can cause diseases in humans, animals, or plants. To prevent and control the occurrence of infections, it is necessary to kill pathogens to cut off the transmission route, maintain environmental hygiene, and protect the health of humans, animals, or plants.

[0003] Existing disinfection methods include two categories: physical disinfection methods and chemical disinfection methods. Physical disinfection methods include methods such as heat, ultraviolet light, and radiation. Chemical disinfection methods mainly use disinfectants for soaking, wiping, or atomization for disinfection. Among them, the atomization method is an ideal method for disinfecting a certain space such as a room, which can comprehensively cover the indoor air and the surfaces of objects at one time, and can disinfect efficiently without damaging items.

[0004] However, the disinfection aerosol generated by existing atomization devices has relatively large particles and a short hovering time in the space. And because the aerosol cannot hover in the air for a long time, the disinfection range is small, and it is difficult to disinfect positions such as the dead corners of buildings.

[0005] Therefore, how to provide a device that can extend the residence time of the disinfection aerosol in the air while reducing the impact on the environment and the human body is a technical problem that needs to be urgently solved by those skilled in the art. Summary of the Invention

[0006] To solve the above technical problems, the object of the present invention is to provide a spraying device; the spraying device provided by this application has the synergist aerosol output by the second atomizer located below the disinfectant aerosol output by the first atomizer when spraying. When the synergist aerosol rises, it will mix with the disinfectant aerosol and carry the disinfectant aerosol upward to diffuse, thereby utilizing the function that the synergist can suspend for a long time to extend the suspension time of the disinfectant aerosol mixed with it, thereby slowing down the sedimentation of the disinfectant aerosol, improving the disinfection effect and duration, and thus achieving suspension without dead corners and a large action range.

[0007] The technical solution provided by the present invention is as follows:

[0008] A spraying device, comprising:

[0009] A first storage tank for storing disinfectant;

[0010] A second storage tank for storing synergist;

[0016] Preferably, the outlets of the first atomizer and the second atomizer face the same direction, and the outlet of the first atomizer is located above the outlet of the second atomizer.

[0017] Preferably, along the direction of the aerosol spray, the outlet of the first atomizer is located downstream of the outlet of the second atomizer.

[0018] Preferably, the length of the atomizing tube of the first atomizer extending out of the first atomizer is longer than the length of the atomizing tube of the second atomizer extending out of the second atomizer.

[0019] Preferably, a first valve is further provided between the first storage tank and the first pumping mechanism, the second storage tank is communicated with the first pumping mechanism through a pipeline, and a second valve is provided between the second storage tank and the first pumping mechanism.

[0020] Preferably, a first controller is further provided, and the first controller is electrically connected to the first atomizer, the second atomizer, the first pumping mechanism, and the second pumping mechanism respectively; the first controller is further provided with a first temperature adjustment module and a second temperature adjustment module, and the first temperature adjustment module controls the atomizing temperature of the first atomizer; the second temperature adjustment module controls the atomizing temperature of the second atomizer.

[0021] Preferably, a second controller is further provided, and the second controller is electrically connected to the first atomizer, the second atomizer, the first pumping mechanism, the second pumping mechanism, the first valve, and the second valve respectively.

[0022] Preferably, the second controller is further provided with a third temperature adjustment module and a fourth temperature adjustment module, the third temperature adjustment module controls the atomizing temperature of the first atomizer; the fourth temperature adjustment module controls the atomizing temperature of the second atomizer.

[0023] The spraying device provided by the present application includes a first storage tank for storing disinfectant, a second storage tank for storing synergist, a first atomizer, a second atomizer, a first pumping mechanism, and a second pumping mechanism. The first atomizer is arranged above the second atomizer. When the spraying device provided by the present application works, the second pumping mechanism pumps the synergist out of the second storage tank and transports it through a pipeline to the second atomizer for atomization. At the same time, the first pumping mechanism pumps the disinfectant out of the first storage tank and transports it through a pipeline to the first atomizer for atomization. Then, the synergist aerosol and the disinfectant aerosol are respectively ejected from the outlets of the second atomizer and the first atomizer. The synergist aerosol is located below the disinfectant aerosol when ejected. Then, when the synergist aerosol rises, it will mix with the disinfectant aerosol and carry the disinfectant aerosol upward to diffuse. Thus, by utilizing the function that the synergist can be suspended for a long time, the suspension time of the disinfectant aerosol mixed with it is prolonged, thereby slowing down the sedimentation of the disinfectant aerosol, improving the disinfection effect and duration, and achieving dead - angle - free suspension with a large action range.

[0035] The embodiments of this application are written in a progressive manner.

[0036] Please as Figures 1 to 4 As shown, an embodiment of the present invention provides a spraying device, including:

[0037] A first storage tank 1 for storing disinfectant;

[0038] The second storage tank 2 for storing synergist;

[0039] The first atomizer 3 for atomizing the disinfectant;

[0040] The second atomizer 4 for atomizing the synergist;

[0041] A first pumping mechanism 5 is provided between the first storage tank 1 and the first atomizer 3;

[0042] A second pumping mechanism 6 is provided between the second storage tank 2 and the second atomizer 4;

[0043] The first atomizer 3 is located above the second atomizer 4.

[0044] In view of the problems existing in the prior art, the present application provides a spraying device, including a first storage tank 1 for storing disinfectant, a second storage tank 2 for storing synergist, a first atomizer 3, a second atomizer 4, a first pumping mechanism 5, and a second pumping mechanism 6, and the first atomizer 3 is arranged above the second atomizer 4. When the spraying device provided by the present application works, the second pumping mechanism 6 pumps the synergist out of the second storage tank 2 and transports it to the second atomizer 4 through a pipeline for atomization; at the same time, the first pumping mechanism 5 pumps the disinfectant out of the first storage tank 1 and transports it to the first atomizer 3 through a pipeline for atomization. Then the synergist aerosol and the disinfectant aerosol are respectively ejected from the outlets of the second atomizer 4 and the first atomizer 3. The synergist aerosol is located below the disinfectant aerosol when ejected. Then the synergist aerosol will mix with the disinfectant aerosol when rising, and carry the disinfectant aerosol upward to diffuse, so as to utilize the function that the synergist can suspend for a long time, extend the suspension time of the disinfectant aerosol mixed with it, thereby slowing down the sedimentation of the disinfectant aerosol, improving the disinfection effect and duration, and thus achieving dead - angle - free suspension with a large action range.

[0045] In this application, the synergist stored in the second storage tank 2 can be any substance that can vaporize under certain conditions and can be suspended for a long time. It is more preferably a substance that can vaporize to form a smoke when heated to a certain temperature condition, such as an alcohol substance. Since the smoke formed by the synergist provided in this application is formed by fully vaporizing the synergist itself under heating conditions, there are no problems of environmental pollution and use safety; and the smoke particle size is small, and using the Brownian motion of molecules, it can drive the disinfectant aerosol to stay in the air for a long time. The disinfectant stored in the first storage tank 1 can be any disinfectant that does not change in nature after being atomized and mixed with the synergist and can be suspended for a long time. Peroxides such as hydrogen peroxide and peracetic acid are preferably used. After being atomized, they form a water mist, which can be miscible with the smoke generated by the synergist and has a good disinfection effect. In addition, since the disinfectant and the synergist are atomized in different atomizers respectively, the parameters of the atomizers can be adjusted correspondingly according to the different characteristics of the disinfectant and the synergist to achieve a better atomization effect.

[0046] When using heating to atomize the disinfectant and the synergist, the heating temperature can be adjusted according to the different vaporization temperatures and failure temperature ranges of the disinfectant and the synergist, so as to ensure that the disinfectant and the synergist can be atomized smoothly and avoid the failure of the disinfectant or the synergist from affecting the disinfection effect.

[0047] The first pumping mechanism 5 and the second pumping mechanism 6 used in this application are preferably electromagnetic pumps. When extracting the disinfectant and the synergist, by controlling the power of the pump, the amount of the extracted liquid can also be controlled, so as to control the ratio of the disinfectant aerosol and the synergist aerosol.

[0048] Preferably, the outlet of the first atomizer 3 and the outlet of the second atomizer 4 face the same direction, and the outlet of the first atomizer 3 is located above the outlet of the second atomizer 4.

[0049] Preferably, along the direction of the aerosol ejection, the outlet of the first atomizer 3 is located downstream of the outlet of the second atomizer 4.

[0050] Preferably, the length of the atomizing tube of the first atomizer 3 extending out of the first atomizer 3 is longer than the length of the atomizing tube of the second atomizer 4 extending out of the second atomizer 4.

[0051] Due to the diffusion characteristics of the aerosol, when the first atomizer 3 is arranged above the second atomizer 4, the synergist aerosol will come into contact with the disinfectant aerosol above after diffusion. However, in order to achieve a better mixing effect, it is preferably to set the outlets of the first atomizer 3 and the second atomizer 4 to face the same direction, and set the outlet of the first atomizer 3 above the outlet of the second atomizer 4. Facing the same direction means that when looking down or up along the vertical direction, the angles of the outlets of the two atomizers in the circumferential direction are the same or similar, so that different aerosols can come into contact and mix in a more concentrated space.

[0052] More preferably, along the direction of the aerosol spray, the outlet of the first atomizer 3 is located downstream of the outlet of the second atomizer 4. That is, when looking down or up at the first atomizer 3 and the second atomizer 4 in the vertical direction, along the direction of the aerosol spray, the outlet of the first atomizer 3 is located downstream of the outlet of the second atomizer 4. Then, while the synergist aerosol in the second atomizer 4 diffuses forward along its spraying direction, it will also diffuse upward. After having spread a certain distance, it comes into contact with the disinfectant aerosol just sprayed above, improving the mixing and driving effect of the synergist on the disinfectant.

[0053] The outlet of the first atomizer 3 being located downstream of the outlet of the second atomizer 4 can be achieved by controlling the length of the atomizing tube extending out of the atomizer. The length of the atomizing tube of the first atomizer 3 extending out of the first atomizer 3 is set to be longer than the length of the atomizing tube of the second atomizer 4 extending out of the second atomizer 4. Then, not only can the synergist aerosol be better miscible with the disinfectant aerosol, but the heat and kinetic energy contained in the synergist aerosol can also drive the disinfectant water droplets condensed at the atomizing tube of the first atomizer 3 into the air, reducing the residue of the disinfectant water droplets, thereby reducing the corrosive effect of the disinfectant on the equipment.

[0054] Preferably, a first valve 7 is further provided between the first storage tank 1 and the first pumping mechanism 5. The second storage tank 2 is connected to the first pumping mechanism 5 through a pipeline, and a second valve 8 is provided between the second storage tank 2 and the first pumping mechanism 5.

[0055] More preferably, the second storage tank 2 for storing the synergist is not only connected to the second atomizer 4 through the second pumping mechanism 6, but also connected to the first pumping mechanism 5 through a pipeline. And a second valve 8 is provided between the second storage tank 2 and the first pumping mechanism 5. When the spraying mechanism is working normally, the second valve 8 is closed to cut off the connection between the second storage tank 2 and the first pumping mechanism 5, without interfering with the atomization of the disinfectant and the synergist through the first atomizer 3 and the second atomizer 4 respectively.

[0056] When it is necessary to clean the spraying mechanism, especially to remove the disinfectant to reduce the corrosive effect of the disinfectant on the pipelines and various components inside the equipment, through the cooperation of the first valve 7 provided between the first storage tank 2 and the first pumping mechanism 5 and the second valve 8, it is possible to use the synergist in the second storage tank 2 or cleaning agents such as temporarily contained water to clean the spraying mechanism. Specifically, the first valve 7 is closed, the second valve 8 is opened, and then the first pumping mechanism 5 is started. At this time, the first pumping mechanism 5 can only extract liquid from the second storage tank 2 and send it into the first atomizer 3. Then, the liquid in the second storage tank 2 can wash away the disinfectant in the pipeline and the first atomizer 3.

[0057] Preferably, a first controller 9 is further provided, and the first controller 9 is electrically connected to the first atomizer 3, the second atomizer 4, the first pumping mechanism 5, and the second pumping mechanism 6 respectively; the first controller 9 is further provided with a first temperature adjustment module 91 and a second temperature adjustment module 92, and the first temperature adjustment module 91 controls the atomization temperature of the first atomizer 3; the second temperature adjustment module 92 controls the atomization temperature of the second atomizer 4.

[0058] For the first atomizer 3 and the second atomizer 4 used in this application, a heating atomizer is preferably used. After the disinfectant or synergist is fed into the corresponding atomizer, it flows in the spirally wound vaporization tube and is heated by the thermal energy of the heating resistance wire outside the vaporization tube, thereby being converted into an aerosol.

[0059] Preferably, a first controller 9 is provided, which is electrically connected to the first atomizer 3, the second atomizer 4, the first pumping mechanism 5, and the second pumping mechanism 6 respectively and controls the operation of the above components; and a first temperature adjustment module 91 and a second temperature adjustment module 92 are provided to control the atomization temperatures of the first atomizer 3 and the second atomizer 4 respectively to meet the different requirements of the disinfectant and the synergist.

[0060] Preferably, a second controller 10 is further provided, and the second controller 10 is electrically connected to the first atomizer 3, the second atomizer 4, the first pumping mechanism 5, the second pumping mechanism 6, the first valve 7, and the second valve 8 respectively.

[0061] Preferably, the second controller 10 is further provided with a third temperature adjustment module 101 and a fourth temperature adjustment module 102, and the third temperature adjustment module 101 controls the atomization temperature of the first atomizer 3; the fourth temperature adjustment module 102 controls the atomization temperature of the second atomizer 4.

[0062] When the first valve 7 and the second valve 8 are provided in this application, preferably, the controller is electrically connected not only to the first atomizer 3, the second atomizer 4, the first pumping mechanism 5, and the second pumping mechanism 6, but also to the first valve 7 and the second valve 8. To distinguish it from the previous solution, the controller is named the second controller 10 here. The second controller 10 can not only control the spraying device to form a synergist aerosol and a disinfectant aerosol, but also, when stopping for cleaning, control the operation of the first valve 7, the second valve 8, and the first pumping mechanism 5 to use the liquid in the second storage tank 2 to clean the first atomizer 3.

[0063] The second controller 10 can also be provided with a third temperature adjustment module 101 and a fourth temperature adjustment module 102 to adjust the atomization temperatures of the first atomizer 3 and the second atomizer 4 respectively to meet the different requirements of the disinfectant and the synergist.
