Description

Horizontal door handle with automatic disinfection

This creation is about a horizontal door handle with automatic disinfection, especially a horizontal door handle that uses UV disinfection.

The door handle is mounted on the door as a convenient component to assist in opening and closing the door. People entering and leaving the door will touch the door handle by hand, so the door handle is a highly contagious way of infection.

In view of this, the utility model of the Chinese Patent No. CN2128299Y relates to an ultraviolet disinfection door handle, which can effectively disinfect the door handle by ultraviolet rays, but the ultraviolet light is not good for human skin after all, and excessive irradiation even causes skin lesions. Therefore, CN 103015791 A mentions a sterilizable door handle, which is also provided with an ultraviolet lamp, which is characterized in that when the door handle is held by the hand, the ultraviolet light is cut off, and the ultraviolet light continues after the hand leaves the door handle. Irradiation.

However, the general door handle is made of stainless steel, and the material itself can inhibit the proliferation of germs. It does not require uninterrupted ultraviolet radiation all the time. In the case of a door that has passed for more than one month, such irradiation is wasteful. Therefore, an innovative ultraviolet irradiation door handle is required, and it is wise to irradiate the ultraviolet rays in a time range when the person is not using it, so that the sterilization can be avoided, thereby solving the above problem.

The purpose of this creation is to provide a horizontal door handle with automatic disinfection function, which not only avoids the user to irradiate the ultraviolet light when holding the door handle, but also can irradiate the ultraviolet light at the most critical time after the grip, and achieve the best in the most energy-saving manner. Sterilization effect.

This creation is about a horizontal door handle with automatic disinfection function. It is installed on the door. The horizontal door handle can control the bolt on the door. The horizontal door handle system includes the seat body, curved handlebar, UV lamp and proximity sensor. , start switch, and logic judgment module.

The seat system is fixed to the door; the curved handle extends from the seat body, and has a shaft portion and a hand-held portion, wherein the rotating hand portion rotates the shaft portion with the shaft center to control the bolt. The ultraviolet lamp is disposed around the joint of the connecting portion connecting the shaft portion for generating ultraviolet rays to illuminate the hand portion.

The proximity sensor is disposed in the hand-held portion. When the user holds the hand-held portion, the proximity sensor generates a sensing signal; the activation switch is disposed in the horizontal door handle, and when the hand-held portion rotates, in a predetermined range of travel The start switch is triggered to generate a start signal.

The logic judging module is coupled to the proximity sensor, the start switch, and the ultraviolet lamp. The logic judging module is set to the preliminary open mode when the sensing signal and the start signal are simultaneously generated, and the logic judging module is in the preliminary open mode. When the sensing signal disappears, the mode is set to the on mode. After the start mode is started and the predetermined time range before the sensing signal is generated, the ultraviolet lamp is electrically connected to the power source for ultraviolet irradiation.

The resetting of the hand-held portion can be assisted by a gas spring piston, and the problem of the predetermined time range can be solved by the slow reset of the gas spring piston. Alternatively, the manner in which the hand-held portion is reset may also take only a spring, and in this case, assistance of a timer is required to solve the problem of the predetermined time range.

Therefore, the present invention provides a horizontal door handle with automatic disinfection function, and the proximity sensor can prevent the user from being exposed to ultraviolet rays when the user holds the door handle, and then utilizes the logic judgment module from the proximity sensor and the start switch. The obtained signal is logically judged, and it can be irradiated with ultraviolet rays at the most critical time after holding, which not only has the best sterilization effect, but also considers energy saving and avoids waste.

Please refer to FIG. 1. FIG. 1 is a schematic view showing the appearance of the horizontal door handle 20 of the present invention. The present invention relates to a horizontal door handle 20 having an automatic disinfection function, a horizontal door handle 20 or an L-shaped door handle, which is mounted to the door 10, and a horizontal door handle 20 for controlling the bolt 12 on the door 10. The horizontal door handle 20 is visible from the exterior to include a seat body 30, a curved handle 32, and an ultraviolet lamp 34.

The seat body 30 is fixed to the door 10; the curved handle 32 extends from the seat body 30, and has a shaft portion 3202 and a hand portion 3204. The hand portion 3204 is rotated in the rotation direction D1 to rotate the shaft portion 3202 with its axis. Thereby, the action of opening and closing the door is completed by the control pin 12. The ultraviolet lamp 34 is disposed around the connection of the connecting portion 3204 to the shaft portion 3202, and the illumination path is directed toward the surface of the hand portion 3204 for generating an ultraviolet irradiation hand portion 3204 for disinfecting the hand portion 3204.

Please refer to FIG. 2, which is a schematic diagram of the function of the horizontal door handle 20 of the present invention. The portion of the horizontal door handle 20 that is not easily visible from the exterior further includes a proximity sensor 40, a start switch 42, and a logic determination module 44.

The proximity sensor 40 is disposed on the handheld portion 3204 or disposed near the handheld portion 3204. When the user holds the handheld portion 3204, the proximity sensor 40 senses the presence of the hand to generate the sensing signal 50. The start switch 42 is disposed in the horizontal door handle 20. When the hand portion 3204 is rotated, the start switch 42 is triggered within a predetermined stroke range during the rotation to generate the start signal 52.

The logic determination module 44 is coupled to the proximity sensor 40, the activation switch 42, and the ultraviolet lamp 34. The logic determination module 44 is set to the preliminary on mode when the sensing signal 50 and the activation signal 52 occur simultaneously, which may occur when the user is turning the hand portion 3204 by hand. The logic determination module 44 is set to the on mode when the sensing signal 50 disappears in the ready-on mode, which occurs when the user's hand leaves the hand-held portion 3204. The ultraviolet lamp 34 is electrically connected to the power source for ultraviolet irradiation within a predetermined time range after the start mode is started and before the sensing signal 50 is generated again. For example, if the predetermined time range is 5 seconds, the ultraviolet lamp 34 will irradiate the hand-held portion 3204 with ultraviolet rays for 5 seconds after the hand portion 3204 is manually rotated and the hand is moved away from the hand-held portion 3204.

The logic determination module 44 can be implemented by using a programmable processor as a core, or can be designed as a logic circuit for interpretation. It is a currently implementable technology and will not be described herein.

Please refer to FIG. 3. FIG. 3 is a schematic diagram of the first embodiment of the present creation reset control. The horizontal door handle 20 is as described above, wherein the horizontal door handle 20 further includes a gas spring piston 60. The shaft portion 3202 extends into the seat body 30. The shaft portion 3202 of the seat body 30 is a laterally extending rod member 62. The rod member 62 is axially coupled to one end of the gas spring piston 60, and the other end of the gas spring piston 60 is coupled to the shaft. Connected to the inside of the seat body 30. After the hand is held and the hand portion 3204 is rotated in the direction of the arrow, the gas spring piston 60 is compressed. After the grip is released, the gas spring piston 60 has a spring and a gas plug therein, and the spring elastically recovers to extend the gas spring piston 60. However, the air plug and the air in the cylinder block the elongation of the gas spring piston 60, and the hand portion 3204 is slowly reset.

Further, in conjunction with FIG. 2, the logic determination module 44 needs to set the sensing signal 50 to disappear and the activation signal 52 to be set to the on mode. The activation signal 52 continues to occur during the extension of the gas spring piston 60, so that the speed at which the gas spring piston 60 is slowly extended is such that the activation switch 42 corresponds to the predetermined range of travel to produce the predetermined time range. . In other words, as shown in the figure, because the piston rod 6002 is slowly rising, as long as the start switch 42 is designed to grow a strip-shaped electrical contact, and one of the portions of the contact piston rod 6002 is used as the electrical conduction start signal 52, the piston rod 6002 In the slow process, the time range can be generated, that is, the time during which the piston rod 6002 is electrically contacted with the long strip-shaped electrical contact is just the predetermined time range. Therefore, by adjusting the length of the long strip-shaped electrical contact or adjusting the piston rod 6002 air plug to adjust the rising speed, the time of the start signal 52 can be controlled to be the same as the predetermined time range, and the ultraviolet light can be controlled. The length of time that 34 is illuminated, for example five seconds as set forth in the previous example, will illuminate the handpiece 3204 for five seconds.

Please refer to FIG. 4 and FIG. 5. FIG. 4 is a schematic diagram of the second embodiment of the present creation reset control. Figure 5 is a functional diagram of the second embodiment of the present creation. The horizontal door handle 20 as shown in FIGS. 1 and 2, wherein the horizontal door handle 20 further includes a spring 70 and a timer 72. The timer 72 is coupled to the logic determination module 44. The shaft portion 3202 extends into the seat body 30. The shaft portion 3202 of the seat body 30 is connected to one end of the spring 70, and the other end of the spring 70 is coupled to the seat body 30. When the hand grip 3204 is held and rotated in the direction of the arrow, the tension spring 70 is pulled. After the grip is released, the elastic restoring force of the spring 70 resets the hand portion 3204. This reset is relatively fast and difficult to implement as the first implementation. The example uses the slowing of the reset to generate the required predetermined time range, for example five seconds. Therefore, the predetermined time range is calculated by using the timer 72. As in the previous example, after the start mode is started and the timer 72 is counted for five seconds, the logic determination module 44 determines that the ultraviolet lamp 34 has to stop the illumination.

Thereby, the horizontal door handle 20 with automatic disinfection function is provided by the present invention, and the proximity sensor 40 can be used to prevent the user from being exposed to ultraviolet rays when the user holds the door handle, and then the logic determination module 44 is used from the proximity sensor. 40 and the signal obtained by the start switch 42 is logically judged, and the ultraviolet light can be irradiated at the most critical time after the grip, which not only has the best sterilization effect, but also saves energy and avoids waste.
