[0028] Disclosed is a portable sterilization case of PPE (Personal Protective Equipment) with a rechargeable battery. Referring to Fig.l which shows a box body 10 of the disclosed portable sterilization case. The box body 10 is of a container configuration having an opening and an inner volume. The opening can receive an article for sterilization, wherein the size of the article can be proportional to the inner volume of the box body 10. Particularly the box body can have a volume to accommodate a PPE kit for sterilization. Small articles, such as N95 masks, paper currency, coins, gloves, phones, or any personal items can also be sterilized in the disclosed portable sterilization case. The box body 10 includes a base, a front wall, a rear wall, and opposite sidewalls defining the volume of the box body 10. The top of the box body is open to receive an article for sterilization. On an edge of the rear wall can be a fastener 15, such as hinge joints for attaching a cover (shown in Fig. 2). On an edge of the front side can be a locking member 20 for securing the cover to the box body. In one case, the locking member can be a magnet. [0029] Furthermore, shown in Fig. 1 is an elongated UV-C lamp 25 integrated into the base of the box body 10. The UV-C lamp can be configured to provide irradiation in the UV-C range of spectrum having the desired intensity. The construction and working of the UV-C lamps are known in the art. In one case, the UV-lamp can be a solid-state UV lamp. The inner surface of the box body can be made from a reflective material to enhance the efficiency of UV sterilization. The box body can also be provided with hooks 32 for coupling a net. Fig. 1 shows four hooks 32 coupled on the opposite sidewalls of the box body 10, the four hooks can attach the four loops of the net. An exemplary embodiment of the net is shown in Fig. 5. The net 90 is shown to have loops at four comers that can engage with the four hooks shown in Fig. 1. Fig. 1 also shows several spikes 33 configured on the base of the box body 10. The spikes 33 and the net 90 can enhance the efficiency and effectiveness of the sterilization.

[0030] Additionally, the box body 10 can include a charging port 30 for charging of portable electronic device, such as a smartphone, wherein the portable electronic device is secured inside the case 10. The charging port 30 as shown in Fig. 1 extends through a flexible cable, wherein a plug of the charging port 30 can be easily connected to the smart phone. In one implementation, the case body can also be provided with wireless charging option. Any electronic device having wireless charging option can be charged both inside and on top of the sterilization case. For example, the sterilization case can be configured with a QI Wireless charging circuitry for wireless charging.

[0031] Fig. 2 shows an embodiment of the cover 35 that can be coupled with the box body 10 for closing its opening. The cover 35 can include fasteners 40 that correspond to the fastener

15 for coupling the cover to the box body 10. In one case the fasteners 15 and 40 can be a pair of hinge joints for pivotally coupling the cover to the box body. The cover can pivot between a closed position and an open position. In the closed position, the opening of the box body is closed by the cover. While in the open position, the inner volume of the box body is accessible. The cover also comprises a locking member 45 that engages with the locking member 20 of the box body for securing the cover to the box body. In one exemplary embodiment, the locking member can be a magnet/magnet or magnet/iron pair that releasably attaches the cover to the box body.

[0032] The cover can also include a UV-lamp 50 like the UV-lamp of the box body. Both the UV lamps 25 and 50 can simultaneously operate to provide efficient sterilization. The inner surface of the cover can also be made of reflective material for synergizing the UV- sterilization. Referring to Fig. 3, which shows the front side of the disclosed portable sterilization case. The front side of the portable sterilization case can be provided with a recess 55 to lift the cover. The recess can be a protrusion, or a handle coupled to the cover. In one case, the recess can include a locking mechanism as well for securing the cover to the box body. Fig. 3 also shows a button 60 for turning on deep cycle sterilization. The button 60 can trigger a predetermined program defining the intensity of the UV irradiation and the duration. A battery status indicator 65 can show the battery status as well as indicate the charging of the battery. The indicator 70 can show the status of UV lamps. The indicator 70 is off when the UV lamps are off. The indicator 70 can blink showing warming of the UV lamps. A continuous blue indicator can show the normal operation of the UV lamp. While the red indicator can show the deep cycle operation of the UV lamps. Fig. 4 also shows a pair of charging port for charging an electronic device, such as a smartphone. Charging port 80 can be a USB-C type charging port or like known to a skilled person for charging any electronic device. Another charging port 85 can be a USB-C type charging port for wireless charging.

[0033] Fig. 6 shows a control unit 105 operably coupled with a sensor 110, a timing circuitry

115, and a power supply 120. The control unit 105, the sensor 110, the timing circuitry 115, and the power supply 120 can be configured in the case box and the cover of the disclosed portable sterilization case. The sensor can detect the state of the cover i.e. if the cover is in a close state or the open state. The timing circuitry can be configured with a duration for which the UV-lamps should be turned on i.e. the duration of the sterilization cycle. When the cover is closed i.e. switched to the closed state, the event of the closing of the cover can be detected by the sensor and the corresponding signal can be received by the control unit from the sensor. The control unit in response can trigger the timing circuitry which turns the power on to the UV lamps for the predetermined duration. After the predetermined duration, the UV-lamps can be turned off. Moreover, an event of the opening of the cover during the sterilization cycle can trigger the turning of power off to the UV lamps for safety. In one case, the sensor 110 can be a toggle button that can detect the status of the cover. Fig. 1 shows the button 33 on the edge of the box body, such as when the cover is closed, the button is pushed down by the cover. Thus, the button can detect closing and opening of the cover. The opening of the cover, releases the pressure on the button and the button is released, indicating the open state of the cover.

[0034] The disclosed portable sterilization case can be powered by a portable rechargeable battery that can also be housed in the box body or cover. The charging ports of the disclosed portable sterilization case can be powered by the rechargeable battery or any other external power supply. In one case, the charging ports and the wireless charging can be powered by a separate external supply. In an alternate case, the rechargeable battery of the disclosed sterilization case can power the Ql wireless charging circuitry and one or more charging ports. [0035] While the foregoing written description of the invention enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein. The invention should therefore not be limited by the above-described embodiment, method, and examples, but by all embodiments and methods within the scope and spirit of the invention as claimed.
