Description

Technical Field

[0001] The invention relates to the technical field of disinfection equipment, in particular to a multifunctional drying and disinfecting device. Background Art

[0002] Most of the existing small sterilizers only have the function of sterilizing by using ultraviolet light. For a single piece of clothing, the irradiation range of the ultraviolet light is limited, resulting in poor actual sterilization effect and failure to achieve the purpose of sterilization.

[0003] Moreover, the handle of the sterilizer is integrally formed with the box cover or fixedly connected to the box cover, and the handle cannot be folded, resulting in an unsightly, untidy and bulky appearance of the sterilizer. Summary of the invention

[0004] The purpose of the present invention is to provide a multifunctional drying and sterilizing device with good sterilizing effect.

[0005] The object of the present invention is achieved in this way.

[0006] A multifunctional drying and disinfecting device comprises a bottom box, an upper cover and a control circuit board, wherein a storage cavity is arranged on the bottom box, and the upper cover is arranged on the bottom box and seals the storage cavity. The device is characterized in that it also comprises a hot air module and an exhaust fan, wherein the hot air module comprises a flexible hot air hood, a heating device and an ozone disinfection device, wherein a flexible hot air hood is provided with a flexible hot air channel, wherein the heating device and the ozone disinfection device are respectively fixed on the flexible hot air channel, wherein the hot air module is fixed on the bottom wall of the storage cavity in the bottom box, wherein the bottom wall of the storage cavity is provided with ventilation holes, wherein the ventilation holes are connected to the outlet of the flexible hot air channel, wherein the exhaust fan is fixed beside the hot air module, and the exhaust port of the exhaust fan is connected to the inlet of the flexible hot air channel, wherein an air inlet is also arranged on the bottom box, wherein the exhaust port of the exhaust fan is close to the air inlet, and the control circuit board is electrically connected to the heating device, the ozone disinfection device and the exhaust fan. In this sterilizer, the exhaust fan draws in air flow, which is heated by a heating device in a flexible hot air channel and mixed with ozone generated by an ozone disinfection device before entering the storage cavity. This can not only dry objects in the storage cavity, but also utilize ozone to fully contact with objects in the storage cavity, thus having a good disinfection effect. The hot air module design facilitates the assembly and production of the sterilizer.

[0007] The above technical solution can be further improved as follows.

[0008] In a more specific solution, the bottom box includes an outer box and an inner box, the inner box is placed on the inner cavity of the outer box, the inner cavity of the inner box constitutes the storage cavity, the bottom wall of the inner box is provided with the ventilation holes, the gap between the bottom wall of the inner box and the inner cavity of the outer box constitutes the installation cavity, and the hot air module and the exhaust fan are both arranged in the installation cavity. The storage cavity and the installation cavity are isolated to prevent water from entering the installation cavity to affect the normal operation of the electrical components, and the use is safer.

[0009] In a more specific solution, the air inlet is opened on the bottom wall of the outer box of the installation cavity, and the exhaust fan is fixed on the bottom wall of the inner box in the installation cavity and close to the air inlet. The exhaust fan blows the air flow toward the entrance of the flexible hot air channel and forms a negative pressure area, so that the outside air automatically enters the negative pressure area through the air inlet.

[0010] In a more specific solution, the ventilation hole of the bottom wall of the inner box extends downward to form an annular surrounding wall, one end of the flexible hot air hood is sleeved on the annular surrounding wall, and the outer wall of the annular surrounding wall abuts against and is sealed against the inner wall of the flexible hot air hood. The flexible hot air hood and the annular surrounding wall are sealed to allow the high-temperature hot air flow to enter the storage cavity through the air inlet, thereby preventing the high-temperature hot air flow from entering the installation cavity and affecting the normal operation of the electrical components.

[0011] In a more specific solution, the flexible hot air channel is a groove with an open top on the flexible hot air cover, and the top opening of the groove includes a front opening and a rear opening, the front opening is the outlet of the flexible hot air channel, the rear opening is against and sealed against the bottom wall of the inner box, and the flexible hot air cover at the tail end of the rear opening is provided with an inlet of the flexible hot air channel. The front opening is convenient for connection with the annular surrounding wall, and the rear opening is convenient for installing a heating device and an ozone disinfection device.

[0012] In a more specific solution, the inlet of the flexible hot air channel and the outlet of the flexible hot air channel are perpendicular to each other, so that the objects in the storage cavity are not easy to enter the installation cavity through the flexible hot air channel.

[0013] In a more specific solution, the heating device and the ozone disinfection device are arranged at the entrance of the flexible hot air channel. The airflow entering the flexible hot air channel is heated by the high-temperature hot airflow, and the airflow is mixed with ozone at the same time.

[0014] In a more specific solution, the bottom surface of the groove extends upwardly from the outlet of the flexible hot air channel toward the inlet of the flexible hot air channel. Water in the storage cavity will enter the flexible hot air cover through the air inlet. Due to the inclined design of the bottom of the flexible hot air channel, the outlet of the flexible hot air channel is not easy to flow to the inlet of the flexible hot air channel, and is easily dried by the high-temperature hot air flow, thereby avoiding affecting the normal operation of the heating device and the ozone disinfection device.

[0015] In a more specific solution, the two ends of the heating device are embedded in the two side walls of the inlet of the flexible hot air channel, the outlet bottom wall of the flexible hot air channel is provided with a drainage gap, and the ozone outlet of the ozone disinfection device is arranged between the heating device and the exhaust port of the exhaust fan. If there is too much water in the storage cavity, the water flows through the drainage gap of the flexible hot air channel to the top of the air inlet, and flows out of the shell from the air inlet, thereby realizing the drainage function, and the drainage gap prevents the water from contacting the heating device.

[0016] In a more specific solution, the control circuit board is arranged on the side wall of the bottom box, and an ultraviolet disinfection lamp is arranged on the control circuit board, and the ultraviolet disinfection lamp extends into the storage cavity. The ozone disinfection device cooperates with the ultraviolet disinfection lamp to improve the sterilization effect.

[0017] The beneficial effects of the present invention are as follows:

[0018] (1) This sterilizer has a reasonable overall structural design. The exhaust fan draws in airflow, which is heated by the heating device in the flexible hot air channel and mixed with the ozone generated by the ozone sterilizer before entering the storage cavity. This can not only dry the objects in the storage cavity, but also make full contact between the ozone and the objects in the storage cavity. Combined with the ultraviolet disinfection lamp, it has a good disinfection effect. The hot air module design facilitates the assembly and production of the sterilizer.

[0019] (2) Secondly, the flexible protective cover and the annular surrounding wall are easy to install and low in cost. In addition, the flexible protective cover is resistant to high temperatures, allowing high-temperature hot air to enter the storage cavity through the air inlet, thereby preventing high-temperature hot air from entering the installation cavity and affecting the normal operation of electrical components.

[0020] (3) Furthermore, the storage cavity and the installation cavity are isolated from each other to prevent water from entering the installation cavity and affecting the normal operation of the electrical components. The water in the storage cavity will enter the flexible hot air hood through the air inlet. Due to the inclined design of the bottom of the flexible hot air channel, it is not easy for the outlet of the flexible hot air channel to flow to the inlet of the flexible hot air channel, and it is easy to be dried by the high-temperature hot air flow. If there is too much water in the storage cavity, the water will flow through the drainage gap of the flexible hot air channel to the top of the air inlet, and then flow out of the shell from the air inlet, thereby realizing the drainage function and preventing a large amount of water in the storage cavity from accumulating in the flexible hot air channel or the installation cavity, which is safe to use.
