The first control circuit is equipped with an alarm element and multiple timing elements connected in parallel. The second control circuit is equipped with multiple docking ports connected in parallel, through which each headlamp is plugged in. The multiple timing elements are respectively electrically connected to the multiple docking ports through intermediate relays. The timing elements are electrically connected to the alarm element. When any of the timing elements reaches a predetermined time, the alarm element is triggered to provide an alarm reminder.
[0006] In one possible implementation, the first control circuit is a 220V AC circuit.
[0007] In one possible implementation, the second control circuit is a 24V DC circuit.
[0008] In one possible implementation, the timing element is a time relay.
[0009] In one possible implementation, the alarm element is an audible and visual alarm or a buzzer.
[0010] In one possible implementation, there are three of each of the docking ports, the intermediate relay, and the timing element.
[0011] Beneficial effects: Compared with the prior art, the electrical appliance storage system with overtime reminder function provided in this application can issue an alarm reminder when the headlamp is not returned to its place after the predetermined time through the cooperation of the docking port, timing element and alarm element, so as to remind the staff to return the headlamp in time and avoid the headlamp being left in the evaporator chamber and contaminating the chamber.
[0012] These and other objects, features and advantages of this utility model will be fully realized through the following detailed description. Attached Figure Description
[0013] Figure 1 A circuit diagram of the electrical appliance storage system with timeout reminder function of this application is shown. Detailed Implementation
[0014] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.
[0015] Those skilled in the art should understand that, in the disclosure of this specification, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.
[0016] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.
[0017] Evaporation machines are key electronic process experimental devices in semiconductor chip manufacturing and integrated circuit processes. During operation, the equipment undergoes a vacuuming process followed by heating. Because the evaporation machine chamber is a high-vacuum, high-cleanliness environment, cleaning is required before vacuuming. Due to the chamber's special nature, additional lighting equipment is not feasible; typically, workers wear headlamps for cleaning, which can take several tens of minutes. There is a risk of headlamps being left inside the chamber, melting when the equipment heats up and contaminating the chamber. To address this issue, an electrical storage system with a timeout reminder function has been developed. This system issues an alarm if the headlamp is not returned to its designated location within a predetermined time, thus preventing headlamp contamination.
[0018] Specifically, this application provides an appliance storage system with an overdue reminder function, including a first control circuit and a second control circuit. The first control circuit is equipped with an alarm element 10 and multiple timing elements connected in parallel. The second control circuit is equipped with multiple docking ports connected in parallel, through which each headlamp is plugged in. At the same time, the multiple timing elements are electrically connected to the multiple docking ports one by one through intermediate relays, and the timing elements are electrically connected to the alarm element 10. When any of the timing elements reaches a predetermined time, the alarm element 10 is triggered to provide an alarm reminder, thereby preventing the headlamp from being left in the evaporator chamber and contaminating the chamber.
[0019] In one embodiment, the first control circuit is a 220V AC circuit, which can ensure no risk of electric shock and thus guarantee the safety of the staff.
[0020] In one embodiment, the second control circuit is a 24V DC circuit, which can be used directly and is convenient to use.
[0021] In one embodiment, the timing element is a time relay.
[0022] In one embodiment, the alarm element 10 is an audible and visual alarm or a buzzer.
[0023] Specifically, combined Figure 1Taking an example where there are three timing elements, three intermediate relays, and three docking ports, the three timing elements are KT1, KT2, and KT3, the three intermediate relays are KA1, KA2, and KA3, and the three docking ports are labeled SB1, SB2, and SB3 to represent the headlamp status. The headlamp is normally closed when in its original position and normally open when removed. When a worker needs to use the #2 headlamp and removes it, SB2 will disconnect, cutting off the 24V DC power. The intermediate relay KA2 will then be de-energized, and its normally closed contact will close, allowing 220V AC power to flow into the KT2 time relay through the normally closed contact of KA2, starting the timer. If the employee has not returned the headlamp by the set time, the normally open contact of the KT2 time relay will close, and alarm element 10 will emit an audible and visual alarm signal or a sound alarm signal. If the employee returns the headlamp within the predetermined time (e.g., 30 minutes, 1 hour, which can be adjusted according to actual needs), the headlamp will reset, and the electrical storage system will reset without emitting an alarm signal.
[0024] It should be noted that the terms "first" and "second" used in this application are for descriptive purposes only and do not indicate any order. They should not be construed as indicating or implying relative importance, and can be interpreted as names.
[0025] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from the stated principles.
