[0054] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings. See also Figures 1-9 .

[0055] A sterilization and storage box for nursing tools, comprising:

[0056] The base 1 has a first cavity 11 inside it;

[0057] The cover 2 is movably connected to the base 1, and a second cavity 21 is provided inside the cover 2;

[0058] A disinfection device is installed inside the first cavity 11;

[0059] The storage base 4 is mounted on the base 1 and has several storage slots 41 for placing nursing tools. The bottom of the storage slots 41 has an opening 42.

[0060] When the nursing tool is placed on the storage seat 4, the tip of the nursing tool (i.e. the nursing end) extends into the first cavity 11 through the opening 42 and is disinfected by the disinfection device, ensuring the hygiene and safety of the nursing tool.

[0061] To facilitate carrying the storage box and prevent dust from falling into the storage seat 4 and base 1 or onto the care tools, a cover 2 is designed. When the cover 2 is installed on the base 1, the rear end of the care tool is moved into the second cavity 21, preventing the rear end of the care tool from being exposed and ensuring that the care tool and the inside of the storage box are clean and tidy.

[0062] The storage seat 4 is installed inside the upper port of the first cavity 11. The storage seat 4 is a rubber stopper, such as a rubber stopper or a silicone stopper. The storage seat 4 is connected and fixed to the inner wall of the upper port of the first cavity 11 by compression or adhesive. The storage seat 4 can effectively prevent ultraviolet rays from spreading outward, thereby ensuring the safety and reliability during disinfection operations.

[0063] The bottom of the storage tray 41 is used to support the nursing tools to ensure the stability of the placement of the nursing tools. It can also be used to limit the length of the front end of the nursing tools that extends into the first cavity 11, so as to prevent the front end of the nursing tools from contacting the bottom of the first cavity 11 and to ensure the disinfection effect of the disinfection device on the nursing tools.

[0064] When the opening 42 at the bottom of the storage slot 41 makes the storage slot 41 a through slot, the nursing tool is placed in the storage slot 41 and the storage slot 41 undergoes elastic deformation, causing the inner wall of the storage slot 41 to press against the side wall of the nursing tool, thereby ensuring that the nursing tool is stably placed on the storage seat 4; the inner wall of the storage slot 41 and the outer wall of the nursing tool are fixed by friction.

[0065] The storage slot 41 has a structure that is wider at the top and narrower at the bottom to prevent nursing tools from falling into the base 1 and to ensure the stability of the nursing tools. The outer walls of the storage slot 41 are connected with reinforcing ribs 44 to improve the deformation resistance of the storage slot 41 and ensure the stability of the storage slot 41 for storing nursing tools.

[0066] An isolation seat 5 is installed inside the base 1. The isolation seat 5 divides the first cavity 11 into an upper cavity 111 and a lower cavity 112. The upper cavity 111 is used for placing nursing tools, that is, the front end of the nursing tool only extends into the upper cavity 111. The lower cavity 112 is equipped with a disinfection device. The isolation seat 5 has a through hole 51, through which the disinfection device disinfects the nursing tools. The isolation seat 5 is used to cover the disinfection device, thereby preventing the disinfection device from being exposed and affecting the appearance (that is, covering the wires, light board, circuit board and battery of the disinfection device). Only the disinfection lamp 311 of the disinfection device is exposed through the through hole 51, ensuring the overall aesthetics. At the same time, the isolation seat 5 can reduce the contact between dirt or dust and the disinfection device, ensuring the stable operation of the disinfection device.

[0067] Because some nursing tools are quite long, such as tweezers and ear picks, the middle of the isolation seat 5 is recessed to form a receiving groove 52. That is, the isolation seat 5 is provided with a receiving groove 52, which is used for the insertion and placement of the front end of the nursing tool. The bottom of the receiving groove 52 has a through hole 51, and the disinfection lamp 311 of the disinfection device is movably placed in the through hole 51. The disinfection lamp 311 disinfects the nursing tool located in the receiving groove 52. The design of the receiving groove 52 ensures that the front end of the nursing tool can be accommodated and stored.

[0068] The upper edge of the isolation seat 5 moves to abut against the lower edge of the storage seat 4 to support the storage seat 4 and prevent the storage seat 4 from moving within the first cavity 11 when nursing tools are placed, thus ensuring the stability of the storage seat 4 installation. The side wall of the isolation seat 5 abuts against the inner wall of the base 1.

[0069] The lower end of the isolation seat 5 has a protruding post 53, and the bottom inner side of the base 1 is provided with a hollow post 12;

[0070] When the isolation seat 5 is installed in the first cavity 11, the protruding post 53 is inserted into the hollow post 12, which ensures the stability of the isolation seat 5 installation and prevents the isolation seat 5 from moving in the base 1, thereby ensuring the installation of the disinfection lamp 311.

[0071] The side end of the storage seat 4 is provided with a limited rotating groove 43, and the inner wall of the base 1 is provided with a limited rotating part 13;

[0072] When the storage seat 4 is installed into the base 1, the rotation limiting part 13 is movably placed in the rotation limiting groove 43, thereby preventing the storage seat 4 from rotating or tilting within the base 1. At the same time, the rotation limiting part 13 can play a positioning role when the storage seat 4 is installed, making installation convenient.

[0073] A limited rotating groove 54 is provided on the side end of the isolation seat 5;

[0074] When the isolation seat 5 is installed in the base 1, the rotation limiting part 13 is movably placed in the rotation limiting groove 54, thereby preventing the isolation seat 5 from rotating or tilting in the base 1. At the same time, the rotation limiting part 13 can play a positioning role when the isolation seat 5 is installed, which facilitates the installation.

[0075] The disinfection device can be an alcohol sprayer, an ultrasonic humidifier, a steam sterilizer, a high-temperature dryer, or an ultraviolet disinfection device. In this design, the disinfection device is an ultraviolet disinfection device.

[0076] The disinfection device includes:

[0077] The disinfection mechanism 31 is installed at the bottom of the first cavity 11 and is used to disinfect nursing tools; the disinfection mechanism 31 has a lamp plate 312 and a disinfection lamp 311 installed on the lamp plate 312;

[0078] A switch 32 is mounted on a base 1 and is connected to a disinfection mechanism 31 via a wire. The switch 32 has a button and a circuit board. An indicator light 321 is provided on the circuit board. The button is slidably mounted on the side wall of the base 1 and extends into the base 1. The circuit board is installed in the base 1 and is movably connected to the button.

[0079] Battery 33 is installed in base 1 and is connected to sterilization mechanism 31 via wire;

[0080] The charging port 34 is mounted on the base 1 and is connected to the sterilization mechanism 31 via a wire; the charging port 34 is a Type-C charging port.

[0081] The base 1 is provided with a mounting groove 14. The side wall of the mounting groove 14 has a clearance opening 141 for avoiding the wire. The bottom of the mounting groove 14 has a fixing post 142. The lamp plate 312 of the disinfection device is movably placed in the mounting groove 14, and the fixing post 142 passes through the fixing hole 313 of the lamp plate 312. The fixing post 142 prevents the lamp plate 312 from moving in the mounting groove 14, thus ensuring the stability of the lamp plate 312 installation.

[0082] Indicator light 321 is used to display the working status and charging status of the disinfection device. The light panel 312 of the disinfection mechanism 31 can control the lighting time of the disinfection lamp 311, thereby controlling the working time of the disinfection mechanism 31 to achieve the effect of automatically ending the disinfection work without the need for manual shutdown of the disinfection device, saving time and effort.

[0083] The isolation seat 5 is designed to limit the disinfection device, ensuring the stability of the disinfection device installed in the base 1;

[0084] The base 1 is provided with a second mounting groove 15, and the outer side wall of the isolation seat 5 has a first limiting part 55. The battery 33 is snapped into the second mounting groove 15 and the first limiting part 55 moves to abut the upper end of the battery 33.

[0085] The base 1 has a mounting groove 3 16 inside, and the outer side wall of the isolation seat 5 has a mounting groove 4 56. The upper end of the charging interface 34 is engaged in the mounting groove 4 56, and the lower end is engaged in the mounting groove 3 16. The side wall of the mounting groove 3 16 is movable and abuts against the side wall of the charging interface 34.

[0086] The base 1 has a mounting groove 17, and the outer wall of the isolation seat 5 has a mounting groove 57. The upper end of the switch 32 is engaged in the mounting groove 57, and the lower end is engaged in the mounting groove 17.

[0087] The side wall of the isolation seat 5 is provided with several limiting protrusions. The limiting protrusions are L-shaped and have mounting grooves 56. The limiting protrusions abut against the rear end of the charging interface 34. The base 1 is provided with a limiting plate 1 and a limiting plate 2. The upper protrusion of the limiting plate 1 abuts against the front side of the lower end of the charging interface 34. The limiting plate 2 is located at the side end of the limiting plate 1 and abuts against the side wall of the charging interface 34. The protrusion of the limiting plate 1 cooperates with the limiting plate 2 to form a mounting groove 16.

[0088] The side wall of the isolation seat 5 is provided with several limiting protrusions 2. The limiting protrusions 2 are L-shaped and are provided with mounting grooves 6 57. The limiting protrusions 2 abut against the rear side of the circuit board of the switch 32. The base 1 is provided with limiting plate 3 and limiting plate 4. The limiting plate 3 is provided with a groove. The lower end of the circuit board of the switch 32 is inserted into the groove. The limiting plate 4 is located on both sides of the limiting plate 3 and abuts against both sides of the circuit board. The limiting plate 4 and the groove form mounting groove 5 17.

[0089] The upper end of the base 1 has a protruding edge 18, and a locking block 181 is provided on the protruding edge 18; the lower end of the inner wall of the cover 2 is provided with a locking groove 22 and a relief groove 23, the relief groove 23 is connected to the side wall of the locking groove 22 and the lower end face of the cover 2; an anti-detachment part 24 is provided in the relief groove 23, and the anti-detachment part 24 cooperates with the locking groove 22 to form an anti-detachment groove 25;

[0090] When the cover 2 is installed on the base 1, the protruding edge 18 is inserted into the cover 2, and the locking block 181 is inserted into the slot 22 through the relief groove 23. As the locking block 181 moves in the slot 22, under the action of external force, the locking block 181 overcomes the obstruction of the anti-detachment part 24 and is placed in the anti-detachment groove 25. The anti-detachment part 24 moves to abut against the locking block 181 to limit the movement of the locking block 181 in the slot 22, thus ensuring the stability of the cover 2 installation.
