Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an air conditioning energy-saving presence sensor. Background Technology

[0002] Air conditioners, as key devices for regulating indoor temperature and humidity and improving air quality, are widely used in homes, offices, and various public places, providing people with a comfortable indoor environment. With the popularization of energy conservation and environmental protection concepts, air conditioner energy-saving presence sensors have emerged. These sensors detect the presence of people in the air conditioner's installation environment and automatically control the air conditioner's on / off state, effectively avoiding energy waste caused by the air conditioner continuing to run after people leave. They also help extend the service life of air conditioning equipment, making them an important application device in the field of air conditioning energy conservation.

[0003] The applicant obtained the following prior art through a search, specifically, patent CN223294984U discloses a sensing device for air conditioner energy saving, which includes an air conditioner body, a power cord fixedly connected to the air conditioner body, a plug fixedly connected to the end of the power cord away from the air conditioner body, an installation box on the power cord, an infrared sensing sensor fixedly connected to one side of the installation box, a time-delay switch module and a control relay inside the installation box, and a microcontroller on the bottom of the inner wall of the installation box; in use, the plug is connected to a power strip to supply power to the air conditioner body through the power cord, and the infrared sensing sensor can detect whether there are people in the room. The infrared sensing sensor, together with the time-delay switch module, the control relay and the microcontroller, enables the air conditioner body to automatically turn off when no one is present, thereby achieving a sensing energy-saving effect, reducing unnecessary energy waste during use, and making this application more conducive to practical use.

[0004] As can be seen from the patent above, although the energy-saving sensor for air conditioning can automatically shut off the air conditioner when no one is present, thus achieving an energy-saving effect, in actual use, due to its fixed installation structure, the orientation of the sensor is difficult to adjust flexibly after installation. This easily leads to a limited detection range for infrared sensors and other detection components, making it difficult to optimize the sensing angle according to the needs of the actual usage scenario, thus affecting the accuracy and comprehensiveness of personnel detection. In addition, the existing sensor technology also suffers from drawbacks such as cumbersome disassembly and assembly processes. When the equipment needs to be repaired, charged, or its installation location changed, it often requires auxiliary tools and complex operations, which is time-consuming, labor-intensive, and inconvenient to use. Utility Model Content

The housing is equipped with the control system for detecting the presence of personnel and controlling the start and stop of the air conditioner. The base is detachably installed at the bottom of the housing. A ball head is provided on the base. A cone adapted to the ball head is provided on the pedestal. The cone is used to achieve universal positioning and locking of the ball head through the sleeve.

[0008] Preferably, the cone cylinder has several through slots evenly and at intervals along its circumference to divide its cylinder wall into several clamping plates, and the cone cylinder is threadedly engaged with the clamping sleeve so that the several clamping plates clamp the ball head.

[0009] Preferably, a support base is provided inside the cone cylinder to support the ball head, and an arc-shaped groove is formed on the top surface of the support base, the outer dimensions of which are adapted to the ball head.

[0010] Preferably, an annular flange is provided on the inner wall of the top of the jacket; and anti-slip texture is formed on the outer wall of the jacket.

[0011] Preferably, the bottom surface of the base is provided with a plurality of slots spaced apart along its circumference for external hooks to extend into, and the openings of the plurality of slots are respectively formed with limiting protrusions.

[0012] Preferably, the bottom surface of the housing has a plurality of heat dissipation holes along its circumference; the top surface of the housing has a display panel; and the side wall of the housing has a plurality of through holes and is provided with an identification structure and an interface.

[0025] Example 1: This utility model proposes an air conditioner energy-saving presence sensor.

[0026] In one embodiment of this utility model, an air conditioner energy-saving presence sensor includes a housing 1, a base 2, a sleeve 3, a base 4, and a control system. The housing 1 is equipped with a control system for detecting the presence of people and controlling the start and stop of the air conditioner. The base 2 is detachably installed at the bottom of the housing 1. A ball head 7 is provided on the base 2. A cone 5 adapted to the ball head 7 is provided on the base 4. The cone 5 realizes the universal positioning and locking of the ball head 7 through the sleeve 3.

[0027] It should be noted that in this embodiment, a control system is provided inside the housing 1. This control system includes a personnel presence detection module, a signal processing module, and an air conditioning control module. The control system can accurately detect the presence of personnel in the current installation environment of the air conditioner and automatically control the start and stop of the air conditioner based on the detection results, ensuring basic energy-saving effects. This core function is the same as the design concept of achieving air conditioning energy saving by sensing the presence of personnel in existing technologies, such as the air conditioning energy-saving sensing device with announcement number CN223294984U. This embodiment does not improve the detection principle, and the main purpose of this embodiment is to provide an air conditioning energy-saving presence sensor that can flexibly adjust the sensing direction, can be quickly installed and removed without auxiliary tools, and improves the comprehensiveness of detection and ease of use.

[0028] Specifically, such as Figures 1 to 4 As shown, in this embodiment, the ball head 7 on the base 2 and the cone 5 on the base 4 form a precise fit, and the locking effect of the clamp 3 together constructs a reliable universal adjustment mechanism. Furthermore, in actual use, the user only needs to loosen the clamp 3, and the ball head 7 can swing and adjust at multiple angles within the cone 5, thereby driving the housing 1 and the internal control system to adjust their orientation synchronously. This expands the detection range of components such as infrared sensors in the control system, adapting to different spatial layouts and personnel movement trajectories, significantly improving the accuracy and comprehensiveness of personnel detection. Simultaneously, after the angle of the housing 1 is adjusted to the correct position, the user only needs to tighten the clamp 3 to stably lock the ball head 7 in the current position, effectively preventing the housing 1 from shifting its orientation due to vibration or other factors during use. The operation is simple and convenient, improving the flexibility of use.

[0029] Understandably, when it is necessary to remove the housing 1 from the base 4 to repair or charge the control system and other related structural components, the user only needs to loosen the clamp 3 to quickly pull the base 2 and housing 1 from the base 4. The operation is simple and efficient. At the same time, when it is necessary to reinstall the housing 1, simply insert the ball head 7 into the cone 5 and tighten the clamp 3 to make the cone 5 converge to fix the ball head 7. The entire disassembly and assembly process of the housing 1 does not require any auxiliary tools, which greatly reduces the difficulty of operation, saves time and costs, and significantly improves the ease of use and maintenance of the equipment.

[0030] In one embodiment, a hinge rod 6 is provided on the bottom surface of the base 2, tapering downwards from top to bottom. The end of the hinge rod 6 has a ball head 7 for extending into the cone 5. Specifically, as shown... Figures 1 to 3 As shown, since the hinge rod 6 is tapered from top to bottom, it can increase the reserved space between the outer wall of the hinge rod 6 and the jacket 3 in the tilted state, thereby increasing the rotation range of the hinge rod 6 after the ball head 7 and the cone cylinder 5 are inserted and matched. This makes the orientation adjustment of the housing 1 and the internal control system more flexible, and can cover a wider detection area, further expanding the detection range of the detection components in the control system. The structural design is simple and reasonable.

[0031] In one embodiment, the conical cylinder 5 has a plurality of through slots evenly and at intervals along its circumference to divide its cylinder wall into a plurality of clamping plates 8. The conical cylinder 5 is threadedly engaged with the clamping sleeve 3 so that the plurality of clamping plates 8 clamp the ball head 7. Specifically, as shown in the figure Figures 1 to 4 As shown, by evenly and intermittently opening several through slots on the wall of the cone 5, each clamping plate 8 has a certain elastic deformation capacity. When the user tightens the clamping sleeve 3, the clamping sleeve 3 moves downward along the axial direction of the cone 5 through the threaded transmission. Its inner wall will form a uniform squeezing force on the outer side of the clamping plate 8, causing several clamping plates 8 to contract towards the center, thereby accurately clamping the ball head 7 located in the cone 5, and realizing stable locking of the ball head 7 at multiple points. Compared to a single locking structure, this multi-clamping method with 8 clamps simultaneously provides a more uniform clamping force on the ball head 7, resulting in a more reliable locking effect. This effectively prevents the ball head 7 from loosening or shifting its orientation after prolonged use or slight vibration, further ensuring the positional stability and accuracy of the detection components. Furthermore, when adjusting the orientation or disassembling the housing 1, simply unscrew the clamping sleeve 3 in the reverse direction. The clamping plates 8 automatically spring back to their original position under their own elasticity, releasing the clamping restriction on the ball head 7. At this point, the ball head 7 can rotate flexibly or be quickly removed. Throughout the entire adjustment or disassembly process, the user can operate conveniently without any auxiliary tools, significantly reducing operational difficulty and saving time.

[0032] In one embodiment, such as Figure 3 and Figure 4As shown, a support base 9 is provided inside the cone cylinder 5. The support base 9 supports the ball head 7, and an arc-shaped groove is formed on the top surface of the support base 9. The outer dimensions of the arc-shaped groove are adapted to the ball head 7. It can be understood that after the ball head 7 and the cone cylinder 5 are installed, the arc-shaped groove of the support base 9 fits tightly with the surface of the ball head 7, thereby providing uniform support force to the ball head 7, effectively dispersing the pressure on the ball head 7 during adjustment, locking and use, avoiding wear and deformation caused by long-term hard contact between the ball head 7 and the bottom of the cone cylinder 5, and extending the service life of the ball head 7 and the cone cylinder 5; at the same time, the guiding effect of the arc-shaped groove makes the ball head 7 more directional when rotating and adjusting, reducing the occurrence of deviation and jamming, making the orientation adjustment smoother and more precise, and further improving the convenience of operation. In addition, the support base 9 and the clamping plate 8 form a double fixing structure of "lower support and upper clamping", which makes the locking state of the ball head 7 more stable. Even when the equipment is subjected to slight collision or vibration, it can effectively prevent the ball head 7 from shifting, ensuring that the detection component always stays at the preset detection angle, and further ensuring the accuracy of personnel detection.

[0033] In one embodiment, an annular flange 10 is provided on the inner wall of the top of the sleeve 3; anti-slip texture is formed on the outer wall of the sleeve 3. Specifically, as shown in the figure... Figures 1 to 4 As shown, the annular flange 10 on the inner wall of the jacket 3 can form a limiting fit with the end face of the top of the cone 5 when the jacket 3 is tightened. On the one hand, this prevents the jacket 3 from being over-tightened, which would cause excessive compression and deformation of the clamping plate 8, thus protecting the clamping plate 8 and the ball head 7. On the other hand, the annular flange 10 can more concentratedly transmit the locking force of the jacket 3 to the upper area of ​​the clamping plate 8, making the force more even when the clamping plate 8 contracts towards the center, further improving the clamping stability of the ball head 7, and ensuring that the equipment can maintain the preset detection angle even after long-term use or slight vibration, thus ensuring detection accuracy. In addition, the anti-slip texture on the outer wall of the jacket 3 effectively increases the friction between the user's hand and the jacket 3. When adjusting the orientation or disassembling the housing 1, the user can easily turn the jacket 3 without the need for auxiliary tools, simplifying the operation process and making it convenient and reliable to use.

[0034] In one embodiment, such as Figures 1 to 3As shown, the bottom surface of the base 2 is provided with several slots 11 spaced apart along its circumference for external connectors to insert into. Each slot 11 has a limiting protrusion at its opening. Understandably, when the user's environment is unsuitable for installation via the ball joint 7 and cone 5, the slots 11 on the base 2 and the external connector can be used for auxiliary connection. Specifically, the user can align the external connector with the opening of the slot 11 and insert it until the external connector is fully engaged inside the slot 11. At this point, the limiting protrusion at the opening axially limits the external connector, preventing it from accidentally coming out, thus achieving a stable connection between the base 2 and the external connector. This provides the housing 1 with diverse installation options, adapting to more different usage scenarios, such as walls without a smooth adhesive surface or requiring suspended installation, improving usability.

[0035] In one embodiment, such as Figure 1 and Figure 3 As shown, the bottom surface of the housing 1 has several heat dissipation holes 12 arranged circumferentially; the top surface of the housing 1 has a display panel 13; and the side walls of the housing 1 have several through holes 14 and are equipped with marking structures 15 and interfaces 16. Understandably, the control system inside the housing 1 will generate heat during long-term operation. The heat dissipation holes 12 on the bottom surface of the housing 1 can form an air circulation channel and quickly dissipate the internal heat, thereby preventing the high-temperature environment from affecting the operational stability and service life of the control system, ensuring that the equipment can continuously and reliably perform personnel detection and air conditioning control functions. Furthermore, the display panel 13 on the top surface of the housing 1 is electrically connected to the control system, and can intuitively display key detection and operation information such as personnel presence status, equipment operating mode, and power level. Users can quickly grasp the equipment status without additional operation, improving ease of use. The through holes 14 on the side walls correspond to the positions of the detection components in the control system, thereby reducing the obstruction of detection signals by the housing 1, ensuring smooth signal transmission, and further improving the sensitivity and accuracy of personnel detection. In addition, the labeling structure 15 can clearly mark the device's parameters, name, operation instructions, functional areas and other information, making it easy for users to quickly become familiar with the usage methods; while the interface 16 can be used as a charging interface or a data interface, which not only meets the power supply needs of the device for long-term use, but also provides a convenient channel for subsequent function debugging and parameter updates. The structural design is simple and reasonable.

[0036] In one embodiment, such as Figure 2 As shown, an adhesive piece 17 is provided on the bottom surface of the base 4, so that users do not need to perform destructive operations such as drilling or nailing on the installation surface when installing the base 4. They only need to peel off the protective film on the surface of the adhesive piece 17, align the base 4 with the preset installation position such as a wall or a flat area around the air conditioner, and press it to adhere. The adhesive force of the adhesive piece 17 can quickly fix the base 4. The installation process is simple and efficient and will not damage the installation surface.

[0037] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art.
