Description

Technical Field

[0001] This application relates to the field of air quality monitoring, specifically to an air quality monitoring instrument. Background Technology

[0002] An air quality monitor is an instrument used to measure and analyze the concentration of pollutants in the air. It can monitor a variety of air pollutants, including but not limited to particulate matter (such as PM2.5 and PM10), harmful gases (such as carbon monoxide, sulfur dioxide, nitrogen dioxide, ozone, etc.), volatile organic compounds, and other substances that may affect air quality.

[0003] Air quality monitors use sensors inside their housing to monitor pollutants in the air and transmit the relevant information to a display screen on the outside of the monitor. The data is then fed back to the user, for example, through a digital display.

[0004] In related technologies, when the number of air inlets in the monitor is too small and the number of sensors inside the monitor is too large, the monitoring accuracy of the sensors will be affected due to insufficient air intake. On the other hand, if the monitor casing has too many air inlets, dust can easily enter the sensor. Utility Model Content

[0005] This application provides an air quality monitor that can maximize the air intake inside the monitor and reduce the possibility of dust in the air entering the monitor.

[0006] This application provides an air quality monitor, including:

[0007] The outer casing has a receiving cavity and a first vent hole communicating with the receiving cavity;

[0008] An air monitoring component, wherein the air monitoring component is disposed within the receiving cavity; and

[0009] The display component is disposed on the outside of the housing and is directly opposite the first vent hole. There is a flow gap between the display component and the housing, and external gas can enter the receiving cavity through the flow gap and the first vent hole in sequence.

[0017] Optionally, in some embodiments, the outer casing is recessed on the side facing the display component towards the receiving cavity to form a recessed region, the display component is disposed in the recessed region, and the first vent is opened in the area of ​​the recessed region opposite to the display component.

[0018] Optionally, in some embodiments, the sidewall of the recessed area is provided with a plurality of second vent holes communicating the receiving cavity with the outside, the plurality of second vent holes surrounding the first vent hole; and / or

[0019] The recessed area includes a mounting surface and a side surface located outside the mounting surface. The display component is mounted on the mounting surface and spaced apart from the mounting surface. The back side surface of the display component is opposite to and spaced apart from the side surface of the recessed area.

The status indication structure includes a plurality of different status indication sections, each indicating a different air quality state. The drive device is used to drive the status indication structure to move so that the status indication section corresponding to the current air quality state is located outside the housing, and the status indication sections other than the one corresponding to the current air quality state are located inside the housing.

[0025] This application provides an air quality monitor, including a housing with a receiving cavity and a first vent connecting the receiving cavity; an air monitoring component disposed within the receiving cavity; and a display component disposed on the outside of the housing and facing the first vent.

[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, for example, 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, a front cover 12, and a rear cover 13, wherein the front cover 12 and the rear cover 13 are located on both sides of the casing body 11 and are arranged opposite to each other. A receiving cavity 111 is formed on the side of the casing body 11 near the front cover 12. The air monitoring component 3 is fixed in the receiving cavity 111 and can be fixed to the casing body 11 by the front cover 12, thereby shielding the receiving cavity 111 and protecting the air monitoring component 3.

[0039] The size of the front cover 12 is adapted to the size of the side of the shell body 11 where the receiving cavity 111 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 111 is opened, or it can be equal to the side of the shell body 11 where the receiving cavity 111 is opened. The specific situation can be set according to the actual situation, and this embodiment does not limit it.

[0040] 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 111 is opened, and through holes are opened at the corresponding positions on 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.

[0041] Of course, the connection between the front cover 12 and the shell body 11 can also be a sliding connection. A T-shaped groove is vertically formed on the surface of the shell body 11 on the side where the receiving cavity 111 is opened, penetrating the top surface but not the bottom surface. 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.

[0042] 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 111 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.

[0043] 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. 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 fixed to the circuit board 31 with screws and electrically connected to the circuit board 31 via wires.

[0044] The shell body 11 is fixed with a plurality of support columns located in the receiving cavity 111. 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.

[0045] Meanwhile, a control chip is also fixed on the circuit board 31. The control chip is electrically connected to the display screen 41 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 display screen 41, thereby controlling the display screen 41 to change its indication state.

[0046] The non-display surface of the display component 41 is provided with a first positioning part 413, and the outer casing 1 is provided with a second positioning part 125 around the first vent 121. The first positioning part 413 and the second positioning part 125 are adapted to each other. Specifically, the first positioning part 413 can be a positioning post fixed to the non-display surface of the display component 41, and the second positioning part 125 is a positioning hole opened on the outer casing 1. Of course, the relationship between the two can also be reversed, that is, the first positioning part 413 can be a positioning hole opened on the non-display surface of the display component 41, and the second positioning part 125 can be a positioning post fixed on the outer casing 1. The positioning post can be inserted into the positioning hole to position the display component 41, thereby ensuring that the display component 41 is installed correctly as much as possible.

[0047] Furthermore, the display component 4 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 method of fixing the display screen 41. This embodiment does not limit the method. Of course, in another embodiment, the display component may also include a baffle plate. This embodiment uses the display screen as the display component for detailed description.

[0048] Taking the first positioning part 413 as a positioning post and the second positioning part 125 as a positioning hole as an example, in one embodiment, in order to ensure the correct installation of the display screen 41 and to prevent the display screen 41 from moving during the installation process, the positioning post is vertically fixedly connected to the non-display surface of the display screen 41, and the positioning hole is opened on the front cover 12, corresponding to the position of the positioning post. When the positioning post is aligned with the positioning hole and inserted into the positioning hole, the display screen 41 can be positioned to prevent the display screen 41 from moving and to facilitate the fixing of the display screen 41.

[0049] Of course, in some embodiments, the positioning part can also be a positioning mark. The positioning mark can be set at the position near the corner of the non-display surface of the display screen 41. There can be one positioning mark or two diagonally arranged. Similarly, the front cover 12 is provided with a mark corresponding to the positioning mark. During the installation process, the user can match the positioning mark on the display screen 41 with the mark on the front cover 12, thereby ensuring the accuracy of the installation position of the display screen 41 and preventing the display screen 41 from being installed backwards.

[0050] The display screen 41 is electrically connected to the control chip via wires. When the control chip receives signals from the 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 supply, as well as to the control chip and sensors. The power supply module provides power to the control chip, display screen 41, and sensors.

[0051] Reference Figure 2 and Figure 4 A flow passage gap 8 is provided between the non-display surface of the display screen 41 and the outer casing 1. The front cover 12 has several first vent holes 121 penetrating through it. When the front cover 12 is fixed to the casing body 11, the first vent holes 121 can communicate with the receiving cavity 111 and connect to the outside through the flow passage gap 8. At this time, air can enter the receiving cavity 111 through the first vent holes 121 and come into contact with the sensor. The flow passage gap 8 connects the outside with the first vent holes 121, thereby allowing the display screen 41 to shield against dust while allowing air to enter the receiving cavity 111 through the flow passage gap 8 and the first vent holes 121.

[0052] Furthermore, one or more isolation components are provided between the non-display surface of the display screen 41 and the outer casing 1. In this embodiment, the isolation components are several isolation ribs 411. That is, several isolation ribs 411 are provided between the non-display surface of the display screen 41 and the side of the front cover 12 away from the casing body 11, thereby separating the front cover 12 from the display screen 41. The non-display surface of the display screen 41 is the back of the display screen 41. In this embodiment, the display screen 41 is rectangular. On the back of the display screen 41, a mounting post 412 is fixed at each of the four corners near the display screen 41. The mounting post 412 has screw holes, and the corresponding position of the front cover 12 has through holes. The user can pass screws through the through holes and the threaded holes in sequence and tighten the screws so that the display screen 41 and the front cover 12 can be fixed by screws.

[0053] Multiple isolation components are distributed at least around the first vent 121. Specifically, the isolation rib 411 is located between the display screen 41 and the front cover 12, and is arranged around the first vent, that is, the isolation rib 411 surrounds the first vent 121 within an annular area, thereby forming a cavity 9 between the isolation rib 411, the front cover 12, and the display screen 41. Under the isolation effect of the isolation rib 411, an annular gap, namely the flow gap 8, is formed between the display screen 41 and the front cover 12. The cavity 9 connects the flow gap 8 and the first vent 121, so that air can enter the cavity 9 from the outside through the flow gap 8, and then enter the receiving cavity 111 through the first vent 121.

[0054] When there is only one isolation rib 411, the isolation rib 411 is fixed between the front cover 12 and the display screen 41, thereby separating the front cover 12 and the display screen 41. At this time, an annular gap can be formed between the front cover 12 and the display screen 41 around the periphery of the display screen 41. This gap is the flow gap 8. The flow gap 8 surrounds all the first vent holes 121, so that air enters the receiving cavity 111 from the outside through the flow gap 8 and the first vent holes 121 in sequence, thereby contacting the sensor 32 and realizing air detection.

[0055] Of course, in another embodiment, the non-display surface of the display screen 41 can directly contact the front cover 12, and a plurality of connection holes are formed on the non-display surface of the display screen 41, the connection holes communicating with the first vent hole 121, and these connection holes together form a flow gap 8. Alternatively, a connecting plate can be fixedly connected between the non-display surface of the display screen 41 and the front cover 12, one side of the connecting plate being fixedly connected to the non-display surface of the display screen 41, and the other side being fixedly connected to the front cover 12, and a plurality of connection holes communicating with the first vent hole 121 are formed on the side wall of the connecting plate, and these connection holes together form a connection gap 8.

[0056] In one embodiment, the isolation rib 411 is fixed to the back of the display screen 41 and near the edge of the display screen 41. The isolation rib 411 can be integrally formed with the back of the display screen 41, fixed by welding, or glued, that is, fixed to the front cover 12 with glue or double-sided tape. The isolation rib 411 includes a first end and a second end that are opposite to each other, with the side closer to the non-display surface of the display screen 41 being the first end. After the display screen 41 is connected and fixed to the front cover, the first end of the isolation rib 411 is fixedly connected to the non-display surface of the display screen 41, and the second end abuts against the front cover 12. The height of the isolation rib 411 is greater than or equal to the height of the mounting post. Thus, the isolation rib 411 can support the display screen 41 and the front cover 12, forming a gap between them. Air can enter between the display screen 41 and the front cover 12 through the gap and enter the receiving cavity 111 through the first vent 121.

[0057] In this way, the display screen 41 can block the first vent 121 to a certain extent, allowing air to enter the receiving cavity 111 while minimizing the occurrence of dust directly entering the receiving cavity 111 from the first vent 121, and ensuring the aesthetics of the monitor as much as possible.

[0058] In another embodiment, the isolation rib 411 is fixed to the side of the front cover 12 near the display screen 41. The isolation rib 411 can be integrally formed with the front cover 12, or it can be fixed by welding or adhesive bonding, that is, by using glue or double-sided tape to fix the isolation rib 411 to the front cover 12. In this case, the side of the isolation rib 411 near the front cover 12 is the first end. After the display screen 41 and the front cover 12 are connected and fixed to each other, the first end of the isolation rib 411 is fixedly connected to the front cover 12, and the second end abuts against the non-display surface of the display screen 41.

[0059] In one embodiment, refer to Figure 5 The isolation component may also include a support column 7 connected to the non-display surface of the display screen 41. A fixing hole 71, which is a threaded hole, is coaxially formed at the center of the support column 7. Multiple support columns 7 are respectively positioned on the non-display surface near the edge of the display screen 41; in this embodiment, there are four support columns 7. A connecting hole 124, corresponding to the fixing hole 71 of the support column 7, is formed on the side of the front cover 12 near the display screen 41, and the connecting hole 124 penetrates the front cover 12.

[0060] The support column 7 supports the display screen 41. During the connection between the display screen 41 and the front cover 12, the fixing holes 71 of the support column 7 are aligned with the corresponding connecting holes 124. Then, screws are passed through the connecting holes 124 and the fixing holes 71 in sequence, and the display screen 41 is fixed to the front cover 12 by tightening the screws. At the same time, under the support of the support column 7, a flow gap 8 can be formed between the display screen 41 and the front cover 12, so that air can enter the receiving cavity 111 through the flow gap 8 and the first vent hole 121. In this way, the display screen 41 can be supported at the same time, and the material consumption can be reduced.

[0061] Furthermore, in order to better ensure that air can enter the receiving cavity 111 while minimizing the occurrence of dust directly entering the receiving cavity 111 through the first vent 121, all the first vent 121 are located between the display screen 41 and the front cover 12. That is, when the display screen 41 is connected to the front cover 12, the display screen 41 can completely block the first vent 121 when viewed from the front of the display screen 41.

[0062] Furthermore, the outer casing 1 is recessed towards the receiving cavity 111 on the side near the display screen 41 to form a recessed region 123. That is, the front cover 12 is recessed towards the receiving cavity 111 to form the recessed region 123. The recessed region 123 is generally frustum-shaped, and the opening of the recessed region 123 gradually increases from the side near the receiving cavity 111 to the side away from the receiving cavity 111. To prevent scratches during the installation of the display screen 41 into the recessed region 123, the connection between the inner walls of the recessed region 123 is made with a recessed arc surface. Of course, in another embodiment, the recessed region 123 can also be cuboid in shape.

[0063] The opening area of ​​the recessed region 123 is larger than the area of ​​the display screen 41, allowing the display screen 41 to be placed into and fixed within the recessed region 123 through the opening. The first vent 121 is located in the area of ​​the recessed region 123 opposite to the display component 4. Let the side of the recessed region 123 closest to the receiving cavity 111 be the bottom surface of the recessed region 123. Taking the display component 4 as an example, which is the bottom surface of the recessed region 123 where the display screen 41 is mounted, the area of ​​the recessed region 123 opposite to the display component 4 is the bottom surface of the recessed region 123. Therefore, the first vent 121 is located on the bottom surface of the recessed region 123. The isolation rib 411 is located between the bottom surface of the recessed area 123 and the non-display surface of the display screen 41. When the display screen 41 is installed in the recessed area 123, the isolation rib 411 can support the display screen 41, so that gaps can be formed between the perimeter of the display screen 41, the non-display surface and the recessed area 123, thereby facilitating air to enter the recessed area 123 through the gaps and then enter the first vent 121.

[0064] Furthermore, refer to Figure 2 and Figure 3 The inner wall of the front cover 12 has a second vent 122 located within the recessed area 123. In other words, the side wall of the recessed area 123 has a second vent 122 that penetrates the front cover 12, and the second vent 122 connects to the receiving cavity 111. The side wall of the recessed area 123 refers to all surfaces of the recessed area 123 except for its bottom surface. That is, the second vent 122 surrounds the first vent 121.

[0065] Specifically, the recessed area 123 includes a mounting surface 1231 and a side surface 1232 located outside the mounting surface 1231. The display component 4 is mounted on the mounting surface 1231 and spaced apart from it. The back side of the display component 4 is opposite to and spaced apart from the side surface 1232 of the recessed area 123. A second vent 122 is opened on the side surface 1232 of the recessed area 123, and a first vent 121 is opened on the mounting surface 1231 of the recessed area 123. Under the action of the isolation rib 411, the display component 4 is spaced apart from the mounting surface 1231, and the back side of the display component 4 is opposite to the side surface 1232 of the recessed area 123, with a gap between them. The area forming the gap is the flow gap 8.

[0066] With the above-mentioned arrangement, the front cover 12 is recessed inward to form a recessed area 123, and a second vent 122 is provided on the side wall of the recessed area 123, which can further improve the air circulation and allow air to enter the receiving cavity 111 more smoothly. At the same time, due to the shielding of the receiving cavity 111 and the display screen 41, when the monitor is placed normally, dust is not easy to enter the receiving cavity 111 through the first vent 121 and the second vent 122, thus reducing the impact of dust on the monitor.

[0067] Furthermore, the depth of the recessed area 123 is greater than the thickness of the display screen 41, and the depth of the recessed area 123 is greater than or equal to the thickness of the display screen 41 plus the thickness of the isolation rib 411, so that the display screen 41 can be completely located within the recessed area 123, or the screen surface of the display screen 41 is flush with the surface of the front cover 12, so that the display screen 41 can be protected by the front cover 12, thereby minimizing the possibility of the display screen 41 being damaged by collision.

[0068] Meanwhile, in order to improve the ease of use of the monitor, the monitor also includes a voice speaker connected to the outer shell 1, and the voice speaker is electrically connected to the air monitoring component 3 and the power supply component 2. The voice speaker can be a speaker fixed inside the receiving cavity 111 or a speaker fixed outside the shell body 11. The voice speaker can be any device that can play voice.

[0069] After the control chip detects the data from the corresponding sensor, it processes the data and converts it into a corresponding signal, which is then sent to the speaker. The speaker then plays the monitoring results, such as "good", "average", or "poor". The specific settings can be adjusted according to the actual situation, and this embodiment does not impose any restrictions on this.

[0070] 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 111 to the outside. In this way, while the front cover 12 blocks the receiving cavity 111 to protect the air monitoring component 3, air can enter the receiving cavity 111 through the air inlets 5, so that the air can come into contact with the sensor.

[0071] Furthermore, in order to facilitate observation of the air quality status monitored by the monitor, the monitor also includes a drive device 42 disposed inside the housing 1; and a status indication structure 43 connected to the drive device 42, wherein the drive device 42 is used to drive the status indication structure 43 to move in order to indicate different air quality statuses.

[0072] Specifically, a first cavity 112 is formed on the side of the shell body 11 near the rear cover 13. A connecting groove is formed on the upper surface of the shell body 11 along the length of the upper surface of the shell body 11, and the connecting groove connects to the first cavity 112. A connecting hole is formed on the shell body 11, and the connecting hole connects the receiving cavity 111 and the first cavity 112. The connecting hole is located on the vertical centerline of its surface. The status indicator structure 43 is rotatably connected to the first cavity 112. 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. The drive motor can drive the status indicator structure 43 to rotate, so that the status indicator part 431 of the status indicator structure 43 extends from the connecting groove to the outside of the shell body 11.

[0073] The drive shaft of the drive motor 421 extends through the circuit board 31 and the connecting hole into the first cavity 112. The status indication structure 43 includes a connecting plate 431 and a status indication part 432. Each status indication part 432 is different, and different status indication parts 432 can indicate different air quality states.

[0074] Specifically, in this embodiment, 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. After the sensor 32 detects the corresponding air quality state, the drive motor drives the connecting plate 431 to rotate the status indicator 432, thereby enabling the status indicator 432 corresponding to the current air quality state to rotate to the outside of the outer shell 1, and the status indicator 432 other than the one corresponding to the current air quality state to rotate to the inside of the outer shell 1, that is, to rotate into the first cavity 112.

[0075] In one embodiment, there may be one status indicator 432; in another embodiment, there may be multiple status indicators 432. This application uses multiple status indicators as an example. If there are multiple status indicators 432, different results can be determined based on different status indicators 432. If there is only one status indicator 432, if it extends to the outside of the shell body 11, it can be considered that the air quality is qualified; otherwise, it is unqualified. Of course, in some embodiments, if the status indicator 432 extends to the outside of the shell body 11, it can be considered that the air quality is unqualified; otherwise, it is qualified. This can be set according to the actual situation, and this application does not limit it.

[0076] 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 adhesive or with 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.

[0077] In some embodiments, the indicator 4321 includes a sticker, a plastic sheet, a template, or an indicator light, etc.

[0078] 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.

[0079] 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 represented by emoticons, such as a smiley face, a calm face, or a 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.

[0080] Reference Figure 6The power supply component 2 includes a battery compartment 21 and a battery 22. The battery compartment 21 is located on the side of the housing body 11 away from the front cover 12, and is situated between the rear cover 13 and the housing body 11. The battery compartment 21 is elongated and located near the bottom surface. Metal conductive plates are fixed to both ends of the battery compartment 21, and these plates are electrically connected to the power supply module via wires. A battery can be placed in the battery compartment 21. When the battery is placed in the battery compartment 21 and its positive and negative terminals 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 via the power supply module.

[0081] 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 can press the battery in the battery compartment 21 tightly, which can prevent the battery from loosening and falling off, resulting in poor contact.

[0082] 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.

[0083] 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 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.

[0084] The shell body 11 has a charging hole located below the charging compartment, and 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.

[0085] 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.

[0086] 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.

[0087] As can be seen from the above, this embodiment includes a housing, a power supply component, and an air monitoring component and a display component connected to the housing. The air monitoring component is connected to the display component, and the power supply component is electrically connected to the air monitoring component and the display component. The housing has a receiving cavity for accommodating the air monitoring component. The display component includes a display screen connected to the air monitoring component. The display screen is disposed on the outside of the housing. The side of the housing near the display screen has several first vent holes communicating with the receiving cavity. The first vent holes are located between the display screen and the housing. Several isolation ribs are provided between the non-display surface of the display screen and the housing. This application utilizes isolation ribs to separate the display screen from the outer casing, creating a gap between them. Simultaneously, a first vent on the outer casing further enhances airflow, allowing air to enter the housing more smoothly. When the monitor is placed normally, the display screen's obstruction prevents dust from easily entering the housing through the first vent, reducing the impact of dust on the monitor. Furthermore, the inward-curving front cover forms a recessed area, and a second vent is provided on the side wall of this recessed area, further improving airflow and allowing air to enter the housing more smoothly. Again, due to the housing and the display screen's obstruction, when the monitor is placed normally, dust is less likely to enter the housing through the first and second vents, reducing the impact of dust on the monitor.

[0088] The above provides a detailed description of an air quality monitor provided in the embodiments of this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
