[0004] ② The equipment is prone to heat generation during operation, which causes problems in user experience;

[0005] ③ Hydrogen peroxide gas is prone to condensation and liquefaction reflux during the spraying process, which easily causes corrosion of the internal coil of the exhaust fan. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a small hydrogen peroxide vaporization device that improves the vaporization and jetting effects of hydrogen peroxide.

[0007] To solve the above technical problems, the utility model provides a small hydrogen peroxide vaporization device, which includes a housing, a liquid storage bottle placed on one side of the housing, and a heating core arranged inside the housing and used for heating hydrogen peroxide solution, so that the hydrogen peroxide solution in the liquid storage bottle is transported to the heating core for evaporation. The outlet end of the heating core is communicated with an exhaust cavity, and an exhaust fan is arranged on one side of the bottom of the exhaust cavity, so that the evaporated hydrogen peroxide gas is blown out along the exhaust cavity by the exhaust fan.

[0008] Furthermore, a pump body is arranged inside the housing, and the pump body is used to connect the liquid storage bottle and the heating core.

[0009] Furthermore, the heating core is wrapped with heat insulation equipment.

[0010] Furthermore, the heating core and the exhaust fan are located on both sides of the bottom of the exhaust cavity, so that the outlet direction of the heating core and the exhaust path of the exhaust fan are both inclined.

[0011] Furthermore, the heating core is inclined, and the angle between the axis of the heating core and the vertical direction is 45°-50°.

[0012] Furthermore, a fixing plate is provided on one side of the exhaust air cavity, and the heating core is connected to the fixing plate.

[0013] Furthermore, a nozzle is connected to the air outlet at the top of the exhaust air cavity, and the nozzle extends towards the outside of the housing.

[0014] Furthermore, a liquid inlet male-female head is provided on the side of the housing, so that both ends of the liquid inlet male-female head are respectively connected to the liquid storage bottle and the pump body.

[0015] Furthermore, a top plate is provided on the top of the housing, and a placement table is provided on one side of the top plate, and the liquid storage bottle is placed in the placement table.

[0016] The beneficial effects of the present utility model are as follows: The hydrogen peroxide solution is stored in the liquid storage bottle. When sterilization is required, the hydrogen peroxide solution is transported to the heating core for heating, so that the hydrogen peroxide solution is evaporated by heat. Then, the vaporized hydrogen peroxide rises along the exhaust air cavity. At this time, the vaporized hydrogen peroxide is blown by the exhaust fan, so that the hydrogen peroxide gas is quickly ejected to the outside, in order to improve the sterilization effect of the hydrogen peroxide gas. And because the hydrogen peroxide needs to be vaporized before it can rise along the exhaust air cavity, the problem that the sterilization effect is reduced due to incomplete vaporization of the hydrogen peroxide can be effectively avoided.

Detailed Description of the Embodiment

[0024] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present utility model.

[0025] Those skilled in the art should understand that in the disclosure of the present utility model, the orientation or positional relationship indicated by terms such as "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on the present utility model.

[0026] It can be understood that the term "one" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of one element can be one, while in other embodiments, the number of this element can be multiple. The term "one" should not be construed as a limitation on the quantity.

[0027] As Figures 1-6 described, the present utility model provides a small hydrogen peroxide gasification device, including a housing 1, a liquid storage bottle 3 placed on one side of the housing 1, and a heating core 7 provided inside the housing 1 and used for heating the hydrogen peroxide solution, so that the hydrogen peroxide solution in the liquid storage bottle 3 is transported to the heating core 7 for evaporation. The outlet end of the heating core 7 is communicated with an exhaust air chamber 8, and an exhaust fan 13 is arranged on one side of the bottom of the exhaust air chamber 8, so that the evaporated hydrogen peroxide gas is blown out along the exhaust air chamber 8 by the blowing of the exhaust fan 13.

[0028] The hydrogen peroxide solution is stored through the liquid storage bottle. When sterilization is required, the hydrogen peroxide solution is transported to the heating core for heating, so that the hydrogen peroxide solution is heated and evaporated. Then, the gasified hydrogen peroxide rises along the exhaust air chamber. At this time, the gasified hydrogen peroxide is blown by the exhaust fan, so that the hydrogen peroxide gas is quickly ejected to the outside, which is convenient to improve the sterilization effect of the hydrogen peroxide gas. And because hydrogen peroxide needs to be gasified before it can rise along the exhaust air chamber, the problem that the sterilization effect is reduced due to incomplete gasification of hydrogen peroxide can be effectively avoided.

[0029] Among them, the heating core can adopt electric wire heating, induction heating, etc.

[0030] Preferably, a pump body 6 is arranged inside the housing 1, and the pump body 6 is used to connect the liquid storage bottle 3 and the heating core 7.

[0031] Specifically, the peracetic acid solution in the liquid storage bottle is pumped and transported to the heating core by a pump body to ensure the stable transportation of the peracetic acid solution.

[0032] In an embodiment of this solution, the pump body can adopt a peristaltic pump structure.

[0033] Preferably, the heating core 7 is wrapped with a heat insulation device 12.

[0034] Specifically, by wrapping the outside of the heating core with a heat insulation device, during the process of the heating core heating the peracetic acid solution, the internal heat will not dissipate outward, thereby avoiding the problem of overheating of the overall device. At the same time, it can also reduce the energy loss at the heating core and improve the gasification effect of the peracetic acid solution.

[0035] Among them, the heat insulation device can adopt heat insulation asbestos wrapped with a flame retardant material on the outside.

[0036] Preferably, the heating core 7 and the exhaust fan 13 are located on both sides of the bottom of the exhaust air chamber 8, so that the outlet direction of the heating core 7 and the exhaust air path of the exhaust fan 13 are both inclined.

[0037] Specifically, by setting the outlet direction of the heating core and the exhaust air path of the exhaust fan to be inclined, the outlet of the heating core will not directly face the inner wall of the exhaust air chamber, and at the same time, the exhaust fan will not be directly below the bottom of the exhaust air chamber. The advantage of this setting is that the peracetic acid gas rising from the heating core will not be blocked by the inner wall of the exhaust air chamber. At the same time, if condensation and liquefaction occur during the spraying process of the peracetic acid gas and it flows back, at this time, the condensate is blown by the side exhaust air, and since the exhaust fan is not directly below the bottom of the exhaust air chamber, the condensate will not directly fall into the exhaust fan, thereby avoiding the problem of corrosion of the internal coil of the exhaust fan.

[0038] In an embodiment of this solution, the heating core 7 is inclined, and the angle between the axis of the heating core 7 and the vertical direction is 45° - 50°, preferably 47°.

[0039] Preferably, a fixing plate 14 is provided on one side of the exhaust air chamber 8, and the heating core 7 is connected to the fixing plate 14.

[0040] Specifically, through the setting of the fixing plate, the stable connection between the heating core and the exhaust air chamber is improved, thereby ensuring that the peracetic acid gas can smoothly rise and enter the exhaust air chamber.

[0041] Preferably, a nozzle 2 is connected to the air outlet at the top of the exhaust air chamber 8, and the nozzle 2 extends outward from the housing 1.

[0042] Specifically, through the nozzle structure extending to the outside of the housing, after the hydrogen peroxide gas in the exhaust air chamber is blown by the exhaust fan, it can be quickly ejected to the outside along the nozzle position, improving the sterilization effect of the hydrogen peroxide gas.

[0043] Preferably, a liquid inlet male-female head 5 is provided on the side of the housing 1, so that both ends of the liquid inlet male-female head 5 are respectively connected to the liquid storage bottle 3 and the pump body 6.

[0044] Specifically, the connection between the liquid storage bottle and the pump body is ensured to be stable through the liquid inlet male-female head, and pipeline entanglement is avoided.

[0045] In an embodiment of this solution, the liquid inlet male-female head adopts a waterway joint, and both ends are respectively connected to the liquid storage bottle and the pump body through pipelines to ensure the stable transportation of the hydrogen peroxide solution.

[0046] Preferably, a top plate 9 is provided on the top of the housing 1, and a placement table 11 is provided on one side of the top plate 9, and the liquid storage bottle 3 is placed in the placement table 11.

[0047] Specifically, the top of the housing is shielded by the top plate, and at the same time, a placement table is provided on one side of the top plate. The liquid storage bottle is stably carried by the placement table to provide the stability of the liquid storage bottle, and thus ensure the stability of the hydrogen peroxide solution.

[0048] Among them, a bottom plate 10 is further provided at the bottom of the housing. The exhaust fan 13, the exhaust air chamber 8 and other structures inside the housing 1 are supported by the bottom plate 10.

[0049] In an embodiment of this solution, a display screen 4 is further provided on the outside of the housing 1, which can be used to display information such as the temperature of the heating core 7 and the wind speed of the exhaust fan 13.

[0050] The present utility model is not limited to the above-mentioned optimal implementation manner. Anyone can obtain other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in its shape or structure, as long as it has a technical solution identical or similar to the present application, it falls within the protection scope of the present utility model.
