Description

Technical Field

[0001] This utility model relates to the field of vending machine technology, and in particular to a power failure early warning device for vending machines for chilled and fresh goods. Background Technology

[0002] With the accelerating pace of life and diversified consumer demands, vending machines for chilled and frozen goods are becoming increasingly widespread in the market. They provide consumers with fresh food, beverages, and other chilled and frozen products, meeting people's immediate consumption needs in different scenarios.

[0003] However, vending machines for chilled goods face numerous problems caused by power outages. Firstly, chilled goods have strict temperature requirements for storage; a power outage causes the vending machine's refrigeration system to stop working, leading to a rapid temperature rise. This can easily cause the chilled goods to spoil, resulting in significant economic losses. For example, some refrigerated fresh foods may experience bacterial growth and a deterioration in taste shortly after a power outage, rendering them unsellable. Secondly, if staff are not promptly aware of and take appropriate measures when a power outage occurs, it not only affects the quality of the goods but may also lead to consumers purchasing spoiled products, causing consumer dissatisfaction and complaints, and negatively impacting the business's reputation.

[0004] Existing power outage monitoring methods have certain limitations. Some vending machines for chilled goods rely solely on simple indicator lights to show power status. In real-world scenarios, staff may not be able to constantly monitor these lights, especially in large venues or when multiple vending machines are operating simultaneously. This monitoring method struggles to detect power outages promptly. Other monitoring methods require regular manual inspections, which are inefficient and cannot guarantee an immediate response to power outages.

[0005] Therefore, it is necessary to provide a new power failure early warning device for vending machines for chilled and fresh goods to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a power failure early warning device for vending machines for chilled and fresh goods.

A photosensitive sensor for monitoring the lights inside the vending machine is fixedly installed on the bottom wall of the mounting base. A controller electrically connected to the photosensitive sensor is installed on the mounting base. An audible and visual alarm is installed on the controller. A voice alarm and a contact switch for activating and deactivating the voice alarm are also installed inside the mounting base.

[0008] A connecting pipe is fixedly installed on the mounting base, and a fixing plate is fixedly installed on the connecting pipe.

[0009] The connecting pipe is fitted with an icicle and a triggering component for activating a contact switch.

[0010] Preferably, the contact switch is fixedly fitted onto the inner surface of the fixed disk, and the contact switch is electrically connected to the voice alarm.

[0011] Preferably, the mounting base also houses a battery for powering the voice alarm and the photosensitive sensor.

[0016] Preferably, the fixing plate has mounting holes.

[0017] Compared with related technologies, the power failure early warning device for refrigerated goods vending machines provided by this utility model has the following beneficial effects:

[0018] This invention uses a photosensitive sensor to monitor the status of the lighting in real time, while the melting of the icicle triggers a mechanical switch, forming a dual protection system. It features a dual alarm mode with sound and light and voice alarms.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0025] Please see Figures 1 to 4 This utility model provides a power failure early warning device for a vending machine for chilled and fresh goods. The power failure early warning device for a vending machine for chilled and fresh goods includes a mounting base 1, a photosensitive sensor 2, a triggering component 6, and a voice alarm 7.

[0026] In the embodiments of this utility model, please refer to Figure 1 , Figure 2 and Figure 3 A photosensitive sensor 2 for monitoring the lights inside the vending machine for chilled goods is fixedly installed on the bottom wall of the mounting base 1. A controller electrically connected to the photosensitive sensor 2 is installed on the mounting base 1. An audible and visual alarm is installed on the controller. A connecting pipe 3 is fixedly installed on the mounting base 1, and a fixing plate 4 is fixedly installed on the connecting pipe 3. The fixing plate 4 has a mounting hole 4a. A controller electrically connected to the photosensitive sensor 2 is installed on the mounting base 1. An audible and visual alarm is installed on the controller.

[0027] It should be noted that the mounting plate 4 is fixedly installed in the refrigerated goods vending machine using screws, and the photosensitive sensor 2 is kept facing the light in the refrigerated goods vending machine. Therefore, when the refrigerated goods vending machine loses power, its light will turn off. When the photosensitive sensor 2 detects that the light in the refrigerated goods vending machine has turned off, its photosensitive sensor 2 can quickly issue an early warning through the sound and light alarm on the controller, so that the staff can quickly know that the circuit of the refrigerated goods vending machine is damaged or the plug is loose.

[0028] In the embodiments of this utility model, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The mounting base 1 also houses a voice alarm 7 and a contact switch 71 for turning the voice alarm 7 on and off. The contact switch 71 is fixedly fitted onto the inner surface of the mounting plate 4 and is electrically connected to the voice alarm 7.

[0029] An icicle 5 and a triggering component 6 for activating a contact switch 71 are inserted into the connecting pipe 3. A semi-circular opening 3a is provided on one side of the connecting pipe 3. The icicle 5 is inserted into the connecting pipe 3 through the semi-circular opening 3a. The triggering component 6 includes a sliding cylinder 61, which is inserted into the connecting pipe 3 and slidably connected to the inner wall of the connecting pipe 3. A spring 62 is installed at the bottom of the sliding cylinder 61. One end of the spring 62 is fixedly connected to the bottom of the sliding cylinder 61, and the other end of the spring 62 is fixedly connected to the inner bottom wall of the connecting pipe 3. A side plate 63 extending out of the connecting pipe 3 is fixedly installed on one side of the sliding cylinder 61, and an abutment post 64 corresponding to the contact switch 71 is fixedly installed on the side plate 63.

[0030] It should be noted that: the ice column 5 is formed by freezing with water, and then the sliding cylinder 61 is pressed down to compress the spring 62. After the ice column 5 is inserted into the sliding cylinder 61, the sliding cylinder 61 is released, so that one end of the ice column 5 abuts against the inner wall of the fixed plate 4, and the other end of the ice column 5 abuts against the sliding cylinder 61. Thus, under the internal support of the ice column 5, the sliding cylinder 61 abuts against the column 64 and the contact switch 71.

[0031] If the chilled goods vending machine loses power, the ice column 5 will melt while being pressed by the sliding cylinder 61, causing the ice column 5 to break quickly. Therefore, the sliding cylinder 61, under the action of the spring 62, drives the abutment column 64 to abut the contact switch 71, thereby enabling the voice alarm 7 to provide a secondary warning. Together with the sound and light alarm, this further improves the comprehensiveness of the warning after a power outage for the chilled goods vending machine.

[0032] In this solution, the photosensitive sensor 2 monitors the status of the lighting in real time, and the melting of the icicle 5 triggers the mechanical switch, forming a dual protection system with a dual alarm mode of sound and light + voice. The sound and light alarm provides immediate warning, while the voice alarm enhances the reminder effect and avoids failure of a single method. After the icicle 5 melts and breaks after the power is cut off, the spring 62 drives the sliding cylinder 61 to trigger the contact switch 71, ensuring that the mechanical alarm is triggered after the power is cut off.

[0033] Furthermore, the mounting base 1 also houses a battery for powering the voice alarm 7 and the photosensitive sensor 2, thus improving the device's battery life.

[0034] Furthermore, a limiting semicircular sleeve 611 is fixedly fitted into the outer wall of the sliding cylinder 61. The limiting semicircular sleeve 611 is fitted onto the connecting pipe 3 and slidably connected to the connecting pipe 3, thus avoiding the potential risk of the sliding cylinder 61 rotating inside the connecting pipe 3.

[0035] The working principle of the power failure early warning device for refrigerated goods vending machines provided by this utility model is as follows:

[0036] The mounting plate 4 is fixedly installed in the refrigerated goods vending machine using screws, ensuring that the photosensitive sensor 2 is facing the light in the vending machine. Therefore, when the vending machine experiences a power outage, its light will turn off. When the photosensitive sensor 2 detects that the light in the vending machine is off, it will quickly issue a warning via the audible and visual alarm on the controller, allowing staff to quickly know that the vending machine's circuitry is damaged or the plug is loose. The ice is then frozen into an ice column 5 structure by water. The sliding cylinder 61 is then pressed down, compressing the spring 62. The ice column 5 is then inserted into the sliding cylinder 61, and the sliding cylinder is released. The sliding cylinder 61 is positioned so that one end of the ice column 5 abuts against the inner wall of the fixed plate 4, while the other end of the ice column 5 abuts against the sliding cylinder 61. Under the internal support of the ice column 5, the sliding cylinder 61 abuts against the contact switch 71. If the vending machine loses power, the ice column 5 melts while being pressed by the sliding cylinder 61, causing it to break quickly. Therefore, under the action of the spring 62, the sliding cylinder 61 drives the contact switch 71 to abut against the contact switch 71, thereby enabling the voice alarm 7 to provide a secondary warning. Combined with the sound and light alarm, this further improves the comprehensiveness of the warning after a power outage for the vending machine.

[0037] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
