Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to an automatic opening and closing cover assembly. Background Technology

[0002] In clinical medical procedures, disinfectants such as iodine-based solutions are widely used for skin disinfection, such as skin preparation before punctures and injections. Most existing disinfectant bottles use screw-on or flip-top caps, which ensure a tight seal and prevent evaporation. However, in the fast-paced clinical environment, medical staff often leave the bottle open for extended periods to save time, or neglect to replace the cap due to the cumbersome procedures. This leads to excessive evaporation of the disinfectant due to prolonged exposure, resulting in a decrease in the concentration of the active ingredient. Furthermore, the open container opening, continuously exposed to ambient air, may become contaminated with environmental pathogens, significantly increasing the risk of cross-infection. Utility Model Content

[0003] The purpose of this invention is to provide an automatic opening and closing cover assembly to solve one or more technical problems existing in the background art.

[0004] To achieve this objective, the present invention adopts the following technical solution: An automatic opening and closing cap assembly includes a housing, an opening component, and a sensing component. The bottom of the housing is provided with a cap that mates with the mouth of a bottle. The housing has a through-hole for taking liquid medicine. The opening component is located inside the housing. The sensing component is located on the upper surface of the housing with its detection end facing upwards, and is used to detect whether a hand is approaching. When the sensing component detects a hand approaching, the opening component moves away from the liquid outlet. When the sensing component detects that the hand has left, the opening component covers the liquid outlet.

[0005] Preferably, the opening assembly includes a driving component and a baffle. The driving component is located on one side of the liquid inlet, and the baffle is located at the movable end of the driving component. A limiting groove is provided inside the housing, and the baffle slides in cooperation with the limiting groove.

[0006] Preferably, the baffle is a thin stainless steel sheet.

[0007] Preferably, the cover opening assembly includes a servo motor, a first transmission gear, a rocker arm, and a second transmission gear. The second transmission gear is integrally disposed at one end of the rocker arm, and the first transmission gear is disposed at the output end of the servo motor. The first transmission gear meshes with the second transmission gear, and the other end of the rocker arm is movably connected to the baffle.

[0008] Preferably, the baffle plate has a mating groove perpendicular to the limiting groove, and the other end of the swing rod has a limiting post, which slides in conjunction with the mating groove.

[0009] Preferably, the sensing component is a pyroelectric inductive switch.

[0010] Preferably, it also includes a sealing ring, and the bottom of the cover has an annular groove, with the sealing ring disposed in the annular groove.

[0011] Preferably, the inner side of the cover is provided with internal threads.

[0012] Preferably, the housing also includes a sealing cap, the upper surface of which is provided with a recess, the liquid inlet is opened in the recess, the outer periphery of the top of the liquid inlet is provided with an inclined portion, the bottom of the sealing cap is provided with a sealing plug, and the outer side of the sealing plug is in contact with the inner wall of the recess.

[0013] The beneficial effects of this invention are as follows: By setting a cap at the bottom of the casing that can fit with a standard bottle opening, it can replace traditional screw caps / flip caps and is compatible with various disinfectant bottles; by setting a sensing component on the casing, when the sensing component detects that a medical staff member is holding a cotton swab close to the casing, it automatically controls the cap opening component to move away from the dispensing port, making it easy to apply the disinfectant. After use, the cap opening component immediately resets and closes the dispensing port, significantly reducing the disinfectant exposure time, effectively inhibiting evaporation, ensuring stable concentration of the disinfectant components, and avoiding the problem of decreased efficacy due to continuous or frequent opening; at the same time, the automatic opening and closing method eliminates the need for manual opening and closing of the bottle cap, allowing for single-handed application, simplifying the workflow of medical staff, and avoiding human error due to negligence in not closing the bottle cap. By blocking the dispensing port with the cap opening component, the dispensing port remains closed when not in use, preventing pathogenic microorganisms in the environment from entering the bottle and reducing contamination of the disinfectant.

Detailed Implementation

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] This embodiment provides an automatic opening and closing lid assembly, as shown in the attached diagram. Figure 1-4 The device includes a housing 1, a cap opening assembly, a sensing assembly 2, and a battery assembly. The bottom of the housing 1 is provided with a cap 11 that fits with the bottle opening. The housing 1 has a liquid dispensing port 111 that runs vertically through the top and bottom for dispensing liquid. The cap opening assembly is located inside the housing 1. The sensing assembly 2 is located on the upper surface of the housing 1 with its detection end facing upwards, and is used to detect whether a hand is approaching. When the sensing assembly 2 detects a hand approaching, the cap opening assembly moves away from the liquid dispensing port 111. When the sensing assembly 2 detects that the hand has left, the cap opening assembly covers the liquid dispensing port 111. The battery assembly is located inside the housing 1 and is a rechargeable lithium battery used to power the sensing assembly 2 and the cap opening assembly.

[0019] By providing a cap 11 at the bottom of the housing 1 that mates with standard bottle openings, it can replace traditional screw caps / flip caps and accommodate various disinfectant bottles. A sensing component 2 on the housing 1 automatically moves the opening component away from the dispensing port 111 when it detects a medical worker holding a cotton swab near the housing 1, facilitating the dispensing of disinfectant. After use, the opening component immediately resets and seals the dispensing port 111, significantly reducing the disinfectant's exposure time, effectively inhibiting evaporation, ensuring stable concentration of the disinfectant, and avoiding decreased efficacy due to continuous or frequent opening. Furthermore, the automatic opening and closing eliminates the need for manual cap opening, allowing for single-handed dispensing, simplifying the workflow for medical workers and preventing human error due to neglecting to close the cap. The opening component's obstruction of the dispensing port 111 ensures it remains closed when not in use, preventing pathogens from the environment from entering the bottle and reducing contamination of the disinfectant.

[0020] Preferably, the opening assembly includes a driving component and a baffle 32. The driving component is located on one side of the liquid inlet 111, and the baffle 32 is located at the movable end of the driving component. A limiting groove 112 is provided inside the housing 1, and the baffle 32 slides in cooperation with the limiting groove 112. The driving component is used to drive the baffle 32 to cover or move away from the liquid inlet 111. When the sensing component 2 outputs a sensing signal, the driving component drives the baffle 32 to slide along the limiting groove 112, ensuring stable and reliable opening and closing action and avoiding jamming or displacement.

[0021] Preferably, the baffle 32 is a thin stainless steel sheet. The baffle 32 is made of stainless steel, which, due to its high hardness, can withstand the frequent pushing and pulling motions of the drive components over a long period, preventing deformation of the plastic baffle 32 that could lead to uneven opening and closing. The use of stainless steel also provides corrosion resistance, preventing corrosion caused by prolonged contact with volatile disinfectant gases.

[0022] Preferably, the cover opening assembly includes a servo motor 31, a first transmission gear 33, a rocker arm 341, and a second transmission gear 342. The second transmission gear 342 is integrally mounted on one end of the rocker arm, and the first transmission gear 33 is located at the output end of the servo motor 31. The first transmission gear 33 meshes with the second transmission gear 342, and the other end of the rocker arm is movably connected to the baffle 32. By using the servo motor 31 to output rotational motion, the accurate positioning of the baffle 32 can be achieved by controlling its forward and reverse rotation and rotation angle, thereby blocking or moving away from the liquid inlet 111. The first transmission gear 33 is meshed with the second transmission gear 342 to convert the rotational motion output by the servo motor 31 into the swing motion of the rocker arm 341 with the second transmission gear 342 as the axis. The other end of the rocker arm 341 is movably connected to the baffle 32 and the two sides of the baffle slide in cooperation with the inner wall of the limiting groove 112. Thus, under the limitation of the limiting groove 112, the swing of the rocker arm 341 pulls the baffle 32 to block or move away from the liquid outlet 111.

[0023] Preferably, the baffle 32 has a mating groove 321 perpendicular to the limiting groove 112, and the other end of the swing rod has a limiting post 343, which slides in engagement with the mating groove 321. When the swing rod 341 swings and drives the baffle 32 to move, the other end of the swing rod slides in the mating groove 321 and pulls or pushes the baffle 32 away from or blocks the liquid outlet 111 during the sliding process, ensuring smooth opening and closing. The width of the mating groove 321 is slightly larger than the diameter of the limiting post 343 to allow for slight positional deviations and prevent jamming.

[0024] Preferably, the sensing component 2 is a pyroelectric inductive switch. By installing the pyroelectric inductive switch on one side of the dispensing port 111, when a medical staff member's handheld cotton swab passes over the dispensing port 111, the pyroelectric sensor can quickly identify it, avoiding accidental triggering by instruments or paper. Furthermore, it eliminates the need to touch the equipment, avoiding the risk of contamination due to contact and meeting medical aseptic requirements. The pyroelectric inductive switch can use a human infrared sensing module of model HC-SR501, which is small in size and saves safety space.

[0025] Preferably, it also includes a sealing ring 13, and an annular groove 12 is formed at the bottom of the cap 11, with the sealing ring 13 disposed in the annular groove 12. By providing a sealing ring 13 at the bottom of the cap 11, when the cap 11 is closed at the bottle opening, the bottom of the cap 11 and the bottle opening simultaneously press the sealing ring 13, ensuring the seal between the cap 11 and the bottle, and preventing the disinfectant from evaporating from the gap between the cap 11 and the bottle.

[0026] Preferably, the inner side of the cap 11 is provided with an internal thread 14. By providing the internal thread 14 on the inner side of the cap 11, it can be directly screwed into the external thread on the standard disinfectant bottle, which is versatile. The screwing of the cap 11 into the bottle prevents loosening or falling off due to movement or operation.

[0027] Preferably, the device also includes a sealing cap 4. A recess 113 is provided on the upper surface of the housing 1, and a liquid outlet 111 is located within the recess 113. An inclined portion is provided on the outer periphery of the top of the liquid outlet 111. A sealing plug 41 is provided at the bottom of the sealing cap 4, and the outer side of the sealing plug 41 is in contact with the inner wall of the recess 113. Since the baffle 32 is a moving part, there will inevitably be a gap in its movement, making it impossible to achieve a tight static seal. Therefore, this embodiment also includes a sealing cap 4. During working hours or frequent operation, the baffle 32 maintains an automatic opening and closing mode to facilitate quick access and provide a certain degree of sealing, preventing rapid evaporation caused by prolonged exposure. At night or during long-term storage, the sealing cap 4 is closed to ensure a seal. By providing a sealing plug 41 at the bottom of the sealing cap 4, after the sealing cap 4 is installed, the sealing plug 41 is squeezed by the inner side of the recess 113, thereby ensuring a tight seal.

[0028] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
