Description

Technical Field

[0001] The invention relates to the technical field of disinfection, and in particular to a portable auxiliary key device with a disinfection function. Background Art

[0002] In hospitals, shopping malls, communities, office buildings or other public places, elevators, ATMs, public telephones and other devices that require keypads are widely used in daily life and are used very frequently. Keypads are one of the items that hide the most bacteria and viruses. People coming and going will press the keys, which will not only bring bacteria and viruses, but also receive bacteria and viruses from others, causing serious impacts on people's health.

[0003] Especially under the influence of the current COVID-19 epidemic, people's need to prevent contact with keys has become more prominent. In response to this situation, there are generally three existing solutions:

[0004] The first solution is to disinfect the keys regularly.

[0005] For example, the invention of CN102861348A discloses a portable UV-LED sterilizer and its disinfection use, wherein the irradiation part has a battery compartment, a power switch and a working status indicator light; the irradiation part has a gravity sensor for preventing the sterilizer from irradiating upward and burning human eyes, and at least one UV-LED light-emitting chip on the light-emitting surface; the light-emitting chip has an emission wavelength of 250nm to 300nm, preferably 265nm to 280nm. The portable UV-LED sterilizer of the present invention has the characteristics of small size, low-voltage DC power supply, low heat generation, impact resistance, and portability, and is particularly suitable for ultraviolet sterilization and disinfection of tableware, mobile phones, keyboards, elevator buttons, remote controls, underwear and other items.

[0006] This solution requires personnel to sterilize and disinfect the keys regularly. However, since there is a time interval for cleaning, although the bacteria on the keys can be reduced, when people press the keys again, they will still bring bacteria to the keys. Since personnel cannot sterilize and disinfect in time, the bacteria on the keys will still endanger people's health.

[0007] The second solution is to transform the button area.

[0008] For example, the utility model with announcement number CN210048312U discloses an elevator button auxiliary device, including a mounting seat and a plurality of pressing components, wherein the mounting seat is provided with a plurality of first operating areas and a plurality of second operating areas, wherein the plurality of first operating areas and the plurality of second operating areas are evenly spaced in the front-to-back direction, and the plurality of second operating areas are located on the right side of the plurality of first operating areas; the plurality of first operating areas and the plurality of second operating areas correspond to a plurality of floor buttons on the elevator, respectively, and a non-contact inductive switch is provided in each of the first operating areas and each of the second operating areas; the plurality of pressing components are arranged at the bottom of the mounting seat, and are connected to the plurality of non-contact inductive switches in a one-to-one correspondence, and are used to press the plurality of floor buttons respectively. According to the elevator button auxiliary device provided by the utility model, the non-contact inductive switch is used to control the pressing component to press the corresponding floor button, which can reduce the accumulation of germs, thereby reducing the probability of cross infection.

[0009] For example, the utility model with announcement number CN206340468U discloses an elevator button device with a disinfection function, which can self-disinfect in time after the elevator button is pressed. One end of the main body sleeve is placed on the base, and a fixing glue is placed on the base. The rubber ring is placed in the main body sleeve, and the limit card is placed on one end of the rubber ring. The power supply is placed between the rubber ring and the main body tube. The pressure block protrusion is placed on the limit card and is located in the rubber ring. A plurality of sterilization lamps are respectively placed on the other end of the main body sleeve, and the metal strip is horizontally embedded in the limit card, and the two ends extend out of the limit card edge. The main contact piece is placed on the inner wall of the main body sleeve, and the main contact piece extends upward from the bottom end of the inner wall of the main body sleeve, and the gap reserved with the upper edge of the main body sleeve is greater than the thickness of the metal strip. The auxiliary contact piece is placed on the inner wall of the main body sleeve and is parallel to the main contact piece.

[0010] For example, the invention of announcement number CN103417994A provides a multi-purpose cleaning and disinfecting device, including at least one elastic substrate, at least one protective layer combined with one side of the substrate, at least one disinfecting device combined with one side of the substrate, and at least one sensing module combined with the substrate, wherein the sensing module is linked with the disinfecting device. With the help of the above-mentioned structural composition, the present invention can also be applied to elevator buttons, power switches, bank ATMs or telephone buttons. Therefore, before the operator wants to touch the buttons, he will first touch the substrate and the protective layer thereon. When the sensing module senses that the object (finger) is away, the disinfecting device sprays a disinfecting solution on the protective layer to perform a disinfecting action, thereby effectively avoiding the adhesion of bacteria to the hands caused by hand contact.

[0011] However, the technical ideas including the above technical solutions require modification of the key area, which is costly and complex to modify and is difficult to promote in practical applications.

[0012] Another solution is to use portable devices to replace direct contact between hands and buttons. For example, using tools such as paper, toothpicks or pens to replace hands to press buttons is a temporary tool with weak targeting or requires the cooperation of property services. In addition, as a temporary tool, it is difficult to disinfect it at any time, and the effect is also poor in actual application.

[0013] This urgently requires a special elevator auxiliary button device to replace the direct contact between the hands and the buttons, and the elevator auxiliary button device can also be disinfected at any time to ensure safe use. Summary of the invention

[0014] The object of the present invention is to provide a portable auxiliary key device with a disinfection function.

[0015] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0016] A portable auxiliary key device with a disinfection function comprises a base body, one end of which is provided with a pressing part for auxiliary pressing keys, and the pressing part is matched with a disinfection mechanism for disinfecting the pressing part.

[0017] The base is a bullet-shaped structure composed of a cylindrical section and a conical section. The pressing part is arranged at the conical section of the base. The pressing part includes a guide cylinder axially arranged on the conical section and fixed thereto. A guide column slidably matched therewith is arranged in the guide cylinder. An elastic reset unit is arranged between one end of the guide column and the guide cylinder. A pressing head is arranged at the other end of the guide column. A part of the pressing head is exposed at the small diameter end of the conical section. A necking portion is arranged at the small diameter end of the conical section. The necking portion is limitedly matched with the top contact of the pressing head.

[0018] The elastic force reset unit is a reset compression spring arranged along the axial direction of the base body, and two ends of the reset compression spring are respectively connected to the guide column and the guide cylinder.

[0019] The guide sleeve is sealed and fixedly connected to the cone section through a sealing plate.

[0020] The disinfection mechanism comprises a cavity axially arranged in the cylindrical section of the base body, a piston matched with the guide is arranged in the cavity, one side of the piston and the cavity form a disinfection liquid cavity, and an elastic force compensation unit is arranged between the other side of the piston and the cavity;

[0021] The disinfectant cavity contains disinfectant, the conical section of the base body is provided with a flow channel, one end of the flow channel leads to the necking part, a drip hole is provided on the contact surface between the necking part and the pressing head, and the other end of the flow channel extends to communicate with the disinfectant cavity.

[0022] The side wall of the cone section of the base body is provided with a clamping cavity, and the clamping cavity is used as a flow channel.

[0023] The cavity is an annular structure, and the elastic force compensation unit includes a plurality of compensation compression springs arranged circumferentially in the cavity, and the compensation compression springs all extend axially and are respectively connected to the piston and the cavity.

[0024] A battery module is also provided in the base body, and the battery module is located at the central axis of the cavity of the annular structure.

[0025] The base is also provided with a lighting module, a positioning module and / or an alarm module, and the battery module supplies power to the lighting module, the positioning module and / or the alarm module.

[0026] The base is also provided with a writing core, which is located at the central axis of the cavity of the annular structure, and the writing end of the writing core extends outward from the cylindrical section of the base. A pen cap covering the writing end is also provided on one side of the cylindrical section of the base.

[0027] The beneficial effects of the present invention are:

[0028] 1. The present invention provides a special portable auxiliary key device with a disinfection function to replace the direct contact between the hand and the key. When in use, the key is pressed by the pressing part, and the pressing part is disinfected by the equipped disinfection mechanism to avoid the bacteria and viruses on the key from being contacted and transmitted to the user, thereby ensuring safe use.

There is no damage to the device when in use, which is convenient for large-scale promotion and application.

[0029] 2. The specific working principle of the base, the pressing part and the disinfection mechanism of the present invention is as follows: when in use, the person holds the base and presses the button with the assistance of the pressing head to replace the direct contact between the hand and the button. At the same time, when the pressing head presses the button, the pressing head is subjected to force, causing the guide column to shrink backward along the guide cylinder, so that the pressing head is separated from the necking part of the cone section. Since the contact surface between the necking part and the pressing head 4 is provided with a drip hole, the disinfectant in the disinfectant liquid cavity flows to the drip hole through the flow channel under the action of the piston and the elastic compensation unit, and then flows to the surface of the exposed part of the pressing head, thereby disinfecting the pressing head.

[0030] After the pressing head leaves the button, the force on the pressing head disappears, and the guide column is reset under the action of the elastic reset unit, thereby driving the pressing head to reset, so that the pressing head contacts the tapered part of the cone section, blocking the drip hole, and the disinfectant no longer flows out, thus completing an auxiliary button operation.

[0031] 3. The present invention can also integrate a battery module in the base, and cooperate with the lighting module, positioning module and alarm module (the lighting module, positioning module and alarm module can be set at the same time, or any one or two of them can be set) to have lighting function, positioning function and alarm function.

[0032] 4. The present invention can also integrate a writing refill on the base, so that the present invention has a writing function and avoids viruses and bacteria brought by public pens BRIEF DESCRIPTION OF THE DRAWINGS
