Description

Technical Field

[0001] This utility model relates to the field of shared fan technology, and in particular to a shared blower control device for use in universities. Background Technology

[0002] Driven by both the sharing economy and the optimization of university logistics services, shared hair dryers have gradually become a common feature in university dormitories and public washrooms because they solve problems such as "space occupation, electrical safety hazards, and resource waste" associated with students purchasing their own hair dryers. However, the shared hair dryers currently used in universities still have several technical defects and insufficient adaptability to different scenarios in practical applications, as follows:

[0003] Most existing shared hair dryers adopt a basic "simple mounting and plug-in" model, lacking effective return detection and activation control mechanisms. On the one hand, some devices lack dedicated storage and positioning structures, making hair dryers prone to being carelessly placed, lost, or damaged after use, increasing the equipment maintenance costs and management difficulties for university logistics departments. On the other hand, most devices lack identity verification and usage authorization functions, leading to safety risks such as misuse by unauthorized users, prolonged student occupation of equipment resulting in idle resources, or accidental activation when not returned to its proper place, causing the equipment to fall. This makes it difficult to meet the university's needs for "orderly management and efficient utilization" of shared equipment.

[0004] In university settings, student electrical safety is a core priority for logistics management, but existing shared hair dryers generally lack real-time monitoring methods. Firstly, key parameters such as air temperature and wind speed cannot be collected in real time. If overheating or abnormal wind speed occurs due to equipment aging or blocked ducts, it can easily lead to burns, equipment damage, or even short circuits, making early warning and timely intervention difficult. Secondly, some devices lack protective structures for the hair dryer's nozzle, allowing hair, paper scraps, and other foreign objects to easily get caught inside, potentially causing equipment malfunctions and personal safety hazards such as hair entanglement, indicating insufficient safety protection.

[0005] University students often use shared hair dryers for grooming and personal care, but existing equipment doesn't consider this need and lacks integrated auxiliary functions. Students have to carry or search for makeup mirrors, resulting in poor convenience. Furthermore, some externally mounted makeup mirrors are easily exposed to dust and water stains in public environments, leading to mirror contamination, reduced clarity, and a negative impact on the user experience. In addition, some shared hair dryer installation methods are limited and cannot flexibly adapt to the limited space in university public areas, often resulting in obstructed walkways or insufficient stability after mounting. Their adaptability needs improvement.

[0006] In summary, current shared hair dryer equipment in universities has significant shortcomings in terms of management standardization, safety monitoring capabilities, and scenario adaptability. There is an urgent need for a shared hair dryer control device that can achieve "standardized management, safety monitoring, and functional integration" to meet the needs of university logistics management and student user experience. Therefore, this solution proposes a shared hair dryer control device for universities. Utility Model Content

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0027] Reference Figure 1-4 This utility model embodiment is used for a shared hair dryer control device in universities, which includes: a base plate 1, a control unit 2 fixedly connected to the front surface of the base plate 1, a fan storage rack 4 fixedly connected to the front surface of the base plate 1, two sets of fan storage racks 4, a card seat 5 fixedly connected inside the two sets of fan storage racks 4, and a hair dryer 6 detachably connected inside the two sets of fan storage racks 4. The hair dryer 6 is engaged with the card seat 5 by a handle. A monitoring switch 14 is provided on the upper surface of the card seat 5, and the monitoring switch 14 abuts against the handle of the hair dryer 6.

[0028] A control box 8 is fixedly connected to the front surface of the base plate 1. A scanning code 10 and a start switch 9 are located on the front surface of the control box 8. A backpack 11 is fixedly connected to the rear surface of the base plate 1. A mirror frame 12 is slidably connected inside the backpack 11, and a makeup mirror 15 is fixedly connected inside the mirror frame 12. Two sets of fan storage racks 4 have through holes 16 on both sides. Protective nets 17 are fixedly connected to the ends of the through holes 16. The two ends of the blower 6's nozzle are respectively connected to the through holes 16. An anemometer 18 and a temperature probe 19 are located inside the through hole 16 connected to the air outlet of the blower 6. A hanging bracket 13 is fixedly connected to the rear surface of the base plate 1, and a main input cable 3 is fixedly connected to the upper surface of the control unit 2.

[0029] The output end of control box 8 is fixedly connected to the fan power cord 7, and the other end of the fan power cord 7 is connected to the blower 6. Control unit 2 is electrically connected to control box 8, anemometer 18, and temperature probe 19. Two sets of mirror frames 12 are provided, each corresponding to one of the two blowers 6. Monitoring switch 14 is electrically connected to control box 8. A contact block for monitoring switch 14 is provided on one side of the handle of blower 6.

[0030] Working principle: This device uses the control unit 2 as the core module to coordinate multiple components such as the fan storage rack 4, control box 8, and monitoring switch 14. It achieves automated management of the entire process of "activation - usage monitoring - return and reset" of the shared hair dryer 6. The specific use of each stage is as follows:

[0031] I. Equipment Activation Phase: Linking QR Code Verification with Location Detection

[0032] Before using the device, students need to scan the QR code 10 on the front surface of the control box 8 to complete the identity binding process through the backend system, such as linking a campus account or pre-authorizing fees. After successful verification, the backend sends a "startup allowed" signal to the control box 8, and the control box 8 enters the standby state.

[0033] The upper surface of the slot 5 inside the blower storage rack 4 is equipped with a monitoring switch 14, and the contact block on the handle side of the blower 6 abuts against the monitoring switch 14. If the blower 6 is not properly inserted into the slot 5, the monitoring switch 14 cannot be triggered and will send a "not returned" signal to the control box 8. At the same time, the mobile device APP will also display the word "return failed".

[0034] When in use, remove the hair dryer. Once the monitoring switch 14 confirms that the hair dryer 6 is disconnected and the user presses the start switch 9, the control box 8 supplies power to the hair dryer 6 through the fan power cord 7, and the hair dryer 6 is officially started. Manually pull out the mirror frame 12 to remove the makeup mirror 15 from the backpack 11 for use.

[0035] II. Usage Monitoring Phase: Real-time Data Acquisition and Security Management

[0036] The fan storage rack 4 has through holes 16 on both sides. The two ends of the blower 6's air tube connect to the through holes 16, and the through hole 16 corresponding to the air outlet of the blower 6 contains an anemometer 18 and a temperature probe 19. The control unit 2 periodically sends detection commands to the control box 8. When sending the commands, it is ensured that the fan is in standby mode and correctly placed inside the fan storage rack 4. This can be monitored by the monitoring switch 14. After the blower 6 is started, the anemometer 18 collects the air velocity, and the temperature probe 19 collects the air temperature, and the data is synchronously transmitted to the control unit 2.

[0037] When the control unit 2 is electrically connected to the anemometer 18, temperature probe 19, and control box 8, if the control unit 2 analyzes the data and finds that the wind speed is lower than the safety threshold (e.g., due to duct blockage) or the temperature is higher than the safety threshold (e.g., due to equipment failure), it will immediately send a "stop signal" to the control box 8. The control box 8 will then cut off the power supply to the fan power cord 7, causing the blower 6 to stop and await inspection. The protective mesh 17 at the through hole 16 prevents foreign objects from entering the air duct, thus avoiding damage to the internal parts of the blower 6.

[0038] Return and reset phase: return confirmation and device standby

[0039] After the student finishes using the hair dryer, the handle of the hair dryer 6 is repositioned into the slot 5, and the handle contact block abuts against the monitoring switch 14 again. The monitoring switch 14 sends a "reset" signal to the control box 8.

[0040] After receiving the "reset" signal, control box 8 cuts off the power supply to the fan power line 7, and the blower 6 stops. At the same time, control box 8 uploads the usage time data to the backend, completes the billing, and then resets to the scan-ready state.

[0041] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
