[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] like Figures 1 to 6 As shown, the specific structure of this air quality monitor can be as follows:

[0036] An air quality monitor includes a housing 1, a power supply component 2, an air monitoring component 3, and a display component 4. In one embodiment of this application, both the power supply component 2 and the air monitoring component 3 are located within a cavity in the housing 1. The power supply component 2 provides power to both the air monitoring component 3 and the display component 4. When the power supply component 2 starts supplying power, the air monitoring component 3 is activated, monitoring pollutants in the air and transmitting the monitoring results to the display component 4, allowing the display component 4 to show the current air quality. Of course, in other embodiments, the power supply component 2 and the air monitoring component 3 can be located outside the housing 1, or partly inside the cavity and partly outside; the specific arrangement can be determined according to actual conditions. This embodiment of the application describes the situation in detail with both the power supply component 2 and the air monitoring component 3 located within a cavity in the housing 1.

[0037] Specifically, the longitudinal section of the outer shell 1 is an isosceles trapezoid that is narrower at the top and wider at the bottom. The wider side is the bottom surface (or lower surface), and the narrower side is the top surface (or upper surface). This shape design makes the monitor more stable when placed on a table or other load-bearing surface, and it is less likely to tip over.

[0038] The outer casing 1 includes a casing body 11 and a cover plate. The cover plate can be detachably installed on the casing body 11, and the installation method can be snap-fit, plug-in, or by screws, etc.

[0039] Specifically, the cover includes a front cover 12 and a rear cover 13, which are located on opposite sides of the shell body 11. A receiving cavity 113 is provided on the side of the shell body 11 closest to the front cover 12. The air monitoring component 3 is fixed in the receiving cavity 113 and can be fixed to the shell body 11 by the front cover 12, thereby shielding the receiving cavity 113 and protecting the air monitoring component 3.

[0040] The size of the front cover 12 is adapted to the size of the side of the shell body 11 where the receiving cavity 113 is opened. For example, the size of the front cover 12 can be larger than the side of the shell body 11 where the receiving cavity 113 is opened, or it can be equal to the side of the shell body 11 where the receiving cavity 113 is opened. The specific situation can be set according to the actual situation, and this embodiment does not limit it.

[0041] The front cover 12 is provided with a vent hole so that outside air can enter the receiving cavity 113 through the vent hole of the front cover, thereby improving the accuracy of the air quality monitor.

[0042] The front cover 12 and the shell body 11 can be connected by screws. For example, multiple threaded holes are opened on the surface of the shell body 11 on the side where the receiving cavity 113 is opened, and through holes are opened at the corresponding positions of the front cover 12. The number of through holes is the same as the number of threaded holes and their positions correspond, so that screws can be passed through the through holes and threaded holes in sequence. The screws are threaded into the threaded holes, so that the front cover 12 and the shell body 11 can be fixed to each other.

[0043] Of course, the connection between the front cover 12 and the shell body 11 can also be a sliding connection. A T-shaped groove that penetrates the top surface but not the bottom surface is vertically formed on the surface of the shell body 11 on the side where the receiving cavity 113 is opened. A T-shaped block corresponding to the T-shaped groove is fixed on the side of the front cover 12 near the shell body 11. In this way, after aligning the T-shaped block with the T-shaped groove during use, the T-shaped block can be slid into the T-shaped groove from top to bottom, so that the front cover 12 and the shell body 11 can be connected to each other, and at this time, the sides of the front cover 12 and the shell body 11 that are close to each other abut against each other.

[0044] Furthermore, the front cover 12 and the shell body 11 can also be connected by a snap-fit ​​mechanism. For example, a slot communicating with the receiving cavity 113 is provided on the side wall of the shell body 11, and a flexible buckle is fixed on the side of the front cover 12 near the shell body 11, with the buckle's position corresponding to the slot's position. When the front cover 12 and the shell body 11 are aligned and the buckle and slot are aligned, as the front cover 12 and the shell body 11 move closer together, the limiting part of the buckle will insert into the slot, thereby fixing the front cover 12 and the shell body 11. When disassembly is required, by pressing the limiting part in the slot, the buckle deforms, and the limiting part disengages from the slot, at which point the front cover 12 and the shell body 11 can be separated.

[0045] The air quality monitor also includes a circuit board 31. The air monitoring component 3 includes one or more sensors 32 connected to the circuit board 31, including but not limited to temperature and humidity sensors, dust sensors, carbon monoxide sensors, carbon dioxide sensors, formaldehyde sensors, and TVOC (Total Volatile Organic Compounds) sensors, which may be one or more of these. The circuit board 31 also has various interfaces, including but not limited to a power supply interface 23 and a network transmission interface. The sensors 32 can be directly soldered to the circuit board 31, or they can be fixed to the circuit board 31 with screws and electrically connected to the circuit board 31 via wires.

[0046] The shell body 11 is fixed with a plurality of support columns located in the receiving cavity 113. The support columns are coaxially provided with threaded holes, and the circuit board 31 is provided with fixing holes. The support columns and fixing holes correspond one-to-one. During installation, the circuit board 31 can be fixed to the support columns by passing screws through the fixing holes, thereby fixing the circuit board 31 to the shell body 11.

[0047] A control chip is also fixed on the circuit board 31. The control chip is electrically connected to the drive device 42 and the aforementioned sensor. When the chip detects the corresponding data of pollutants in the air, the control chip processes the data and sends the processing result to the drive device 42, thereby enabling the drive device 42 to drive the state indication structure 43 to change its indication state.

[0048] The display component 4 also includes a display screen 41 fixed to the front cover 12. The display screen 41 is located on the side of the front cover 12 away from the shell body 11. The display screen 41 can be fixed by means of double-sided tape or Velcro, or by screws, or by any other means of fixing the display screen 41. This embodiment does not limit the method of fixing the display screen 41.

[0049] An air gap is formed between the display component 4 and the front cover 12. This air gap can be formed by providing an insulating element between the display component 4 and the front cover 12, such as four insulating pillars at the four corners of the non-display surface of the display screen 41, thereby isolating the display component 4 from the front cover 12 and creating the air gap. Furthermore, the front cover 12 has a through hole, allowing air to enter the receiving cavity 113 through the through hole. Air can also enter the space between the display component 4 and the front cover 12 through the air gap, and then enter the receiving cavity 113 through the through hole, enabling the sensor 32 to monitor air contact.

[0050] In some embodiments, the display component 4 may cover the vent on the front cover 12.

[0051] The display screen 41 is electrically connected to the control chip via wires. When the control chip receives signals from various sensors, processes them, and then transmits the signals to the display screen 41 via wires, the display screen 41 can display the current air quality, for example, in digital form. Of course, the wires can be any lines capable of data transmission and power supply. The display screen 41 is also electrically connected to the power supply module on the circuit board 31 via wires. The power supply module is electrically connected to the power source, as well as to the control chip, sensors, and drive device 42. The power supply module provides power to the control chip, display screen 41, sensors, and drive device 42 via the power source.

[0052] Meanwhile, one or more air inlets 5 are provided on both sides of the shell body 11. The air inlets 5 connect the receiving cavity 113 to the outside. In this way, while the front cover 12 blocks the receiving cavity 113 to protect the air monitoring component 3, air can enter the receiving cavity 113 through the air inlets 5, so that the air can come into contact with the sensor.

[0053] The power supply component 21 is located on one side of the drive device 42 and / or the status indication structure 43. That is, the power supply component 21 can be located inside the receiving cavity 113 or on the side close to the first cavity 111. This application takes the example of the power supply component 21 being located inside the first cavity 111.

[0054] Specifically, the power supply component 2 includes a battery compartment 21, in which a power supply battery 22 can be installed. The battery compartment 21 is located on the side of the housing body 11 away from the front cover 12, that is, on the side near the first cavity 111. The battery compartment 21 is located between the rear cover 13 and the receiving cavity 113, and is located near the bottom surface. The battery compartment 21 is elongated. Metal conductive plates are fixed at both ends of the battery compartment 21, and the metal conductive plates are electrically connected to the power supply module through wires. A battery can be placed in the battery compartment 21. When the battery is placed in the battery compartment 21 and the positive and negative terminals of the battery are in contact with the metal conductive plates at both ends of the battery compartment 21, the battery supplies power to the control chip, display screen 41, drive device 42, and various sensors through the power supply module.

[0055] Meanwhile, a buffer 6 is also provided on the back cover 13. The buffer 6 is located at the bottom of the back cover 13 and is directly opposite the position of the battery compartment 21. The buffer 6 can be an elastic component, such as foam, sponge or soft rubber. When the back cover 13 is closed, the buffer 6 can press the battery in the battery compartment 21 tightly, which can prevent the battery from loosening and falling off, resulting in poor contact.

[0056] In some embodiments, a control switch is provided between the battery and the power supply module. By turning the control switch on or off, the air quality monitor can be powered on or off. Alternatively, no control switch is provided; power is supplied when the battery is connected to the power cord, and power is cut off when the connection is broken.

[0057] Furthermore, the power supply component 2 also includes a power supply interface 23, which is electrically connected to the power supply module. The power supply interface 23 is fixed on the circuit board 31. The power supply interface 23 can be, for example, a Type-C interface, or any other type of power supply interface 23. There can be one or more power supply interfaces 23, and they can be of one type or a combination of multiple different types.

[0058] The shell body 11 has a charging hole located below the charging compartment. The charging hole is connected to the receiving cavity 113. The power supply interface 23 is located inside the charging hole. The back cover 13 has a notch at the position corresponding to the charging hole. When the user connects the charging cable to the power supply interface 23, the cable can be inserted into the power supply interface 23 inside the charging hole through the notch to achieve charging.

[0059] Of course, during the process of supplying power to the monitor through the power supply interface 23, the power supply module can directly power the control chip, various sensors, display screen 41, and drive device 42, and can also charge the battery through the power supply module's conversion. This charging and discharging technology is a conventional method at present and will not be elaborated on here.

[0060] In some embodiments, a battery may not be provided, and an external power source may be directly connected to the power supply interface 23 for power supply.

[0061] To facilitate battery removal and adjustment of the status indicator structure 43, the rear cover 13 and the housing body 11 can be connected by an insertion method, such as a snap-fit, similar to the connection method between the front cover 12 and the housing body 11. Alternatively, they can be connected by a sliding insertion method, similar to the connection method between the front cover 12 and the housing body 11. Another option is a hinged connection, where a hinge is fixed on the side of the rear cover 13 closest to the housing body 11, and a snap-fit ​​is fixed on the side of the rear cover 13 furthest from the hinge, thus enabling the rear cover 13 to open and close in the left and right directions.

[0062] In one embodiment, a first cavity 111 is formed between the shell body 11 and the cover plate. Specifically, the first cavity 111 is located on the side of the shell body 11 near the rear cover 13. A connecting opening 112 is formed on the upper surface of the shell body 11 along its length, and the connecting opening 112 connects to the first cavity 111. A connecting hole is formed on the shell body 11, connecting the receiving cavity 113 and the first cavity 111. The connecting hole is located on the vertical centerline of its surface. A status indicator structure 43 is rotatably connected to the first cavity 111. Specifically, the driving device 42 includes a drive motor 421, which is fixed on the circuit board 31 and electrically connected to the power supply module and the control chip.

[0063] The drive shaft of the drive motor 421 extends through the circuit board 31 and the connecting hole into the first cavity 111. The status indication structure 43 includes a connecting plate 431 and a status indication part 432. The connecting plate 431 is circular, and a fixing hole is provided in the center of the connecting plate 431. The fixing hole is triangular, but it can also be rectangular. A fixing block adapted to the fixing hole is fixed on the drive shaft of the drive motor 421. When the fixing block is inserted into the fixing hole, the connecting plate 431 can rotate with the rotation of the drive motor. Each status indication part 432 is different, and different status indication parts 432 can indicate different air quality states.

[0064] In one embodiment, there may be one status indicator 432; in another embodiment, there may be multiple indicators. This application uses multiple indicators as an example. If there are multiple indicators, different results can be determined based on different status indicators 432. If there is only one indicator, if the status indicator 432 extends to the outside of the shell body 11, it can be determined that the air quality is good; otherwise, it is poor. Poor air quality can refer to pollution. Of course, in some embodiments, if the status indicator 432 extends to the outside of the shell body 11, it can be determined that the air quality is poor; otherwise, it is good. This can be set according to the actual situation, and this application does not limit it.

[0065] Reference Figure 3 In this application embodiment, the status indicator 432 is used as one of the three examples. The status indicator 432 is evenly distributed around the drive shaft of the drive motor 421, that is, the status indicator 432 is evenly distributed around the connecting plate 431 and is fixedly connected to the connecting plate 431. The connecting plate 431 and the status indicator 432 can be integrally formed, or they can be fixed later.

[0066] Reference Figure 4 The status indicator unit 432 includes an indicator body 4322 connected to the connecting plate 431 and an indicator label 4321 detachably connected to the indicator body 4322. The indicator label 4321 and the indicator body 4322 can be connected magnetically. For example, the indicator body 4322 can be a magnetic metal, and the indicator label 4321 can be a soft magnetic label. Alternatively, the indicator body 4322 and the indicator label 4321 can be fixed with double-sided tape or Velcro. The indicator label 4321 can be located on the side of the body closer to the display screen 41, on both sides of the indicator body 4322, or on the side of the indicator body 4322 away from the display screen 41. It can be set according to the actual situation, and this embodiment does not limit this.

[0067] The sign body 4322 is fixedly connected to the connecting plate 431. The fixing method can be integral molding or other methods, such as hot-melt fixing or adhesive bonding. The specific method can be selected according to the actual situation, and this embodiment does not limit this. Of course, in one embodiment, the sign body 4322 itself has an indicator mark. The indicator mark can refer to the style of the indicator mark 4321, such as different colors, shapes, and patterns. The indicator mark is located on the surface of the sign body 4322, for example, at the location where the indicator mark 4321 is fixed. The setting method can be set according to the actual situation, such as by embossing, injection molding, or etching. This application does not limit the setting method.

[0068] In some embodiments, the indicator 4321 includes a sticker, a plastic sheet, a template, or an indicator light, etc.

[0069] Reference Figure 5 Different indicator signs 4321 have different indicator symbols. These symbols can be displayed in text form, such as "Excellent," "Good," or "Pollution." They can also be in the form of emoticons, such as "smiley face," "calm," or "sad face," where a smiley face represents "Excellent," a calm face represents "Good," and a sad face represents "Pollution." They can also be represented by colors, such as green for "Excellent," yellow for "Good," and red for "Pollution." Furthermore, they can be represented by symbols, such as "√" for "Excellent," "○" for "Good," and "×" for "Pollution," or combinations thereof.

[0070] The indicator 4321 can be replaced according to actual needs. For example, the back cover 13 can be opened to separate the back cover 13 from the shell body 11, and then the connecting plate 431 can be separated from the drive motor 421, that is, the fixing block can be separated from the fixing hole. Then the user can remove the original indicator 4321 on the indicator body 4322 and replace it with a new indicator 4321.

[0071] Furthermore, each status indicator has a different shape; and / or each status indicator has a different color; and / or each status indicator includes an indicator element, and the indicator element of each status indicator is different. That is, the indicator body 4322 can have different shapes and different colors, and similarly, the indicator element 4321 can also have different colors, different shapes, and different patterns. The status indicators 432 can be distinguished solely by different colors, or solely by different shapes, or by different patterns, or of course, by a combination of these forms.

[0072] For example, taking a mixed form, for excellent air quality, the sign body 4322 could be round, the indicator 4321 green, and the pattern a smiley face. For good air quality, the sign body 4322 could be square, the indicator 4321 yellow, and the pattern calm. For poor air quality, i.e., polluted, the sign body 4322 could be triangular, the indicator 4321 red, and the pattern sad.

[0073] Air quality can be determined by the different shapes of individual sign bodies 4322, by the different colors of individual sign bodies 4322, and by the different colors, shapes, and patterns of individual indicator pieces 4321. In other words, air quality can be determined solely by the differences in sign bodies 4322. If all sign bodies 4322 are the same, air quality can also be determined by the differences in indicator pieces 4321. Of course, it can also be determined by a combination where both are different.

[0074] The first cavity 111 is an incomplete circle. The length from the center of the connecting hole to the outermost edge of the first cavity 111 is greater than or equal to the length from the center of the connecting plate 431 to the farthest end of the status indicator 432. The connecting hole is close to the upper surface of the shell body 11, and the length from the center of the connecting plate 431 to the outermost edge of the connecting plate 431 is greater than or equal to the length from the connecting hole to the upper surface of the shell body 11. As a result, during the rotation of the status indicator 432, the status indicator 432 can rotate completely within the first cavity 111 without stopping due to touching the edge surface of the first cavity 111. Thus, one of the status indicators 432 can be located outside the first cavity 111, while the other status indicators 432 can be completely located within the first cavity 111.

[0075] Of course, in one embodiment, the length from the center of the connecting plate 431 to the outermost edge of the connecting plate 431 can also be less than the length from the connecting hole to the upper surface of the shell body 11, so that the status indicator 432 can display the indicator marker 4321 normally.

[0076] During use, when the sensor detects air quality, if the air quality is excellent, the control chip will control the drive motor 421 to rotate, causing the status indicator 432 to display an indicator 4321 related to "excellent," such as a "smiley face" or a green indicator. Of course, if the air quality is polluted, a "sad face" or a red indicator will be displayed. During the rotation of the drive motor 421, the connecting plate 431 will rotate, and the connecting plate 431 will cause the status indicator 432 to rotate within the first cavity 111, ultimately extending the required status indicator 432 from the communication port 112 to the top of the housing body 11.

[0077] Reference Figure 6In another embodiment, the outer casing 1 has a second cavity 114 for accommodating the status indicator structure 43. The second cavity 114 is rectangular and located between the rear cover 13 and the casing body 11. The driving device 42 includes multiple drive pumps 422 electrically connected to the control chip and the power supply component 2. The drive pumps 422 can be miniature electric cylinders, and the drive rod of the drive pumps 422 is the telescopic rod of the electric cylinder. The electric cylinder is fixed in the second cavity 114 in a direction perpendicular to the top of the casing body 11. Each electric cylinder has a status indicator 432 fixed at the end of its telescopic rod. When the electric cylinder's telescopic rod is in the retracted state, the status indicator 432 is located inside the second cavity 114. When the electric cylinder's telescopic rod is in the extended state, the status indicator 432 is located outside the second cavity 114, that is, it extends to the top of the casing body 11 through the connecting port 112, i.e., the connecting port 112 is located directly above the drive pumps 422.

[0078] The status indicator 432 is detachably connected to the telescopic rod of the electric cylinder. Specifically, the connection can be fixed by the friction of bolts. For example, a cylinder is fixed on the outer surface of the status indicator 432. A circular hole is coaxially opened at the end of the cylinder away from the status indicator 432. The diameter of the circular hole is equal to the diameter of the telescopic rod. A threaded hole is opened on the side wall of the cylinder, which connects to the circular hole. A stud is threaded into the threaded hole. When the telescopic rod is inserted into the circular hole, the stud can be rotated to make the stud abut against the telescopic rod. The friction between the stud and the telescopic rod fixes the telescopic rod to the status indicator 432.

[0079] When the sensor detects air quality, the control chip processes the signal and sends the result to the corresponding electric cylinder. Upon receiving the signal, the electric cylinder is energized to extend the telescopic rod, causing the status indicator 432 to extend from the communication port 112 for user viewing. (For example, refer to...) Figure 6 The status indicator 432 is labeled as excellent, good, and polluted from left to right. When the air quality monitored by the sensor is excellent, the telescopic rod of the electric cylinder on the left extends, causing the status indicator 432 to extend out of the second cavity 114. If the monitoring result is polluted, the telescopic rod of the electric cylinder on the right extends, causing the status indicator 432 to extend out of the second cavity 114. When one status indicator 432 extends out of the second cavity 114, all other status indicator 432s are located inside the second cavity 114.

[0080] As described above, this embodiment includes a housing 1, a power supply component 2, and an air monitoring component 3 and a display component 4 connected to the housing 1. The air monitoring component 3 is connected to the display component 4, and the power supply component 2 is electrically connected to both the air monitoring component 3 and the display component 4. The display component 4 includes a drive device 42 connected to the air monitoring component 3 and a status indication structure 43 connected to the drive device 42. The drive device 42 is used to drive the status indication structure 43 to change its indication state so that the status indication structure 43 is located outside the housing 1. During use, based on the air quality monitoring results from the air monitoring component 3, the drive device 42 can drive the status indication structure 43 to change, thereby allowing for a more intuitive determination of the air quality status based on the markings on the status indication section 432. This application can determine air quality through changes in the status indication structure 43, allowing users to more clearly determine whether the monitored air quality is up to standard, making the use of the air quality monitor simpler and easier to understand.
