Abstract
Description
Technical Field
[0001] This utility model belongs to the field of disinfectant swab technology, and specifically relates to a press-type automatic ejection device for disinfectant swabs. Background Technology
[0002] Disinfecting swabs are widely used for cleaning and disinfecting skin and wounds. They consist of a swab, compound iodine or povidone-iodine or alcohol, with the swab itself consisting of a cotton stalk and a cotton tip. The initial bacterial count of the disinfecting swab should be ≤100 cfu / g, and no pathogenic bacteria should be detected.
[0003] Currently, disinfectant swabs are stored in sealed transparent plastic bags. When using them, the packaging needs to be opened. However, the number of swabs used each time is limited. Since the remaining swabs are not stored separately, they are very easy to contaminate other unused swabs when they are taken out. Utility Model Content
[0004] In view of this, the purpose of this utility model is to address the shortcomings of the existing technology by providing a press-type automatic ejection device for disinfectant swabs, which dispenses one swab per press, is stored independently, is convenient to use, and is more hygienic and safe.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] The automatic ejection device for press-type disinfectant swabs includes a box and a base. The base contains a motor, a controller, a push-button switch, and a power supply. The controller is electrically connected to the motor, the push-button switch, and the power supply.
[0007] The box is set on the base and rotated by a motor. The box is cylindrical and has several through holes evenly and vertically opened at the end of the box along the circumference. Disinfectant swabs can be placed inside the through holes, and elastic baffles are set at both ends of the through holes.
[0008] A top rod is vertically slidably mounted on the base. The top of the top rod passes through an elastic baffle from the bottom of one of the through holes and reaches into the through hole. An elastic element connects the top rod to the base. A button switch is located below the top rod. By pressing the top rod, its top can be disengaged from the through hole, and the bottom of the top rod can be turned downwards to activate the button switch. The controller controls the motor to drive the box to rotate at the angle between two adjacent through holes through the activation signal of the button switch.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0034] Please refer to Figures 1-9 The automatic ejection device for press-type disinfectant swabs provided by this utility model includes a box body 1 and a base 2. The base 2 is equipped with a motor 3, a controller 4, a push-button switch, and a power supply 6. The controller 4 is electrically connected to the motor 3, the push-button switch, and the power supply 6. The motor 3 is a servo-controlled motor, which can precisely control the position of the motor 3. The power supply 6 is a rechargeable battery that provides power to the circuit.
[0035] Please combine Figure 3 , Figure 4 , Figure 6 The box body 1 is mounted on the base 2 and rotated by a motor 3. The motor 3 has a drive shaft connected to a connecting rod, which is inserted into the bottom of the box body 1 to drive its rotation. The box body 1 has a cylindrical structure, and several through holes 101 are evenly and vertically opened along the circumference at its end. Disinfectant swabs can be placed inside the through holes 101. See details... Figure 2 , Figure 5 Elastic baffles 7 are provided at both ends of the through hole 101 to prevent foreign objects from entering the through hole 101 and contaminating the disinfectant swab.
[0036] A top rod 8 is vertically slidable on the base 2. The top of the top rod 8 passes through the bottom of one of the through holes 101, through an elastic baffle 7, and reaches into the through hole 101, pushing the sterile cotton swab inside the through hole 101 upwards and out from above the through hole 101 for retrieval. The elastic baffle 7 has a central cross-shaped opening structure, which serves to block the flow while facilitating the passage of the top rod 8 and the sterile cotton swab. An elastic element 9 connects the top rod 8 to the base 2. When the top rod 8 is pressed, the elastic force of the elastic element 9 allows the top rod 8 to return to its original position. A push-button switch is provided. Below the top rod 8, during use, pressing the top rod 8 causes its top to disengage from the through hole 101, and the bottom of the top rod 8 touches the button switch downwards. This causes the controller 4 to control the motor 3 to drive the box body 1 to rotate at the angle between two adjacent through holes 101 via the touch signal of the button switch. When the top rod 8 is reset under the elastic force of the elastic element 9, the position of the through hole 101 changes due to the rotation of the box body 1. The top rod 8 then moves upwards into a new through hole 101, pushing the disinfectant swabs in the through hole 101 upwards, thus forming a cycle.
[0037] The through-hole 101 is located on the outer edge of the box body 1. The closer it is to the outer edge, the larger the area, and the more through-holes 101 can be made, allowing for more disinfection swabs to be placed, and leaving a larger area in the middle of the box body 1. A storage cavity is provided in the middle of the box body 1, and a lid 10 is provided on the storage cavity for placing other items.
[0038] The base 2 has a cylindrical structure with a vertical groove 201 on its side. A horizontal bar 801 is provided on the side of the top rod 8, extending through the groove 201 to the outside of the base 2. By pressing the horizontal bar 801 from the outside, it moves within the groove 201, simultaneously moving the top rod 8 downwards. This allows other components within the base 2 to be integrated inside, leaving only the end of the horizontal bar 801 exposed on the outside for pressing. A support rod 802 is also provided on the side of the top rod 8. An elastic element 9 is positioned between the support rod 802 and the base 2. The top rod 8 is indirectly and elastically connected to the base 2 via the support rods 802 on both sides, resulting in better stability. In this embodiment, the elastic element 9 is a spring.
[0039] During operation, pressing the end of the crossbar 801 once causes the crossbar 801 to move the top rod 8 downwards. The top of the top rod 8 disengages from the through hole 101, allowing the box body 1 to rotate. The bottom of the top rod 8 touches the button switch downwards. The controller 4 receives the touch signal from the button switch and controls the motor 3 to drive the box body 1 to rotate a certain angle. Then, the top rod 8 is released to reset it. Due to the rotation of the box body 1, the position of the through hole 101 changes. When the top rod 8 resets, it moves upwards to a new through hole 101 and pushes the disinfectant swab in the through hole 101 upwards. Each press causes the system to operate once, pushing the disinfectant swab in one through hole 101 upwards, thus forming a cycle.
[0040] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
