本申请的实施方式
为了使本申请所要解决的技术问题、技术方案及有益效果更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
请一并参阅图1至图15，现对本申请提供的空气质量监测设备进行说明。所述空气质量监测设备，包括进气装置1、空气监测装置2、气泵3和控制装置4，进气装置1内部具有适于空气进入的空腔，在空腔内设有用于加热空气的加热组件11；空气监测装置2的进气口连通空腔的出气口，空气监测装置2用于监测加热后的空气质量；气泵3的进气口连通空气监测装置2的出气口，适于抽吸空气且抽吸的空气通过进气装置1进入空气监测装置2内；控制装置4适于控制加热组件11和气泵3运行，并接收空气监测装置2监测的空气质量信息。
本申请提供的空气质量监测设备，与现有技术相比，本申请空气质量监测设备包括进气装置1、空气监测装置2、气泵3和控制装置4，气泵3抽吸空气，空气依次通过进气装置1和空气监测装置2，进气装置1内的加热组件11对空气加热，便于空气监测装置2监测空气质量，控制装置4控制加热组件11和气泵3运行并接收空气监测装置2监测到的空气质量信息。本申请提供的空气质量监测设备，通过控制装置4控制运行，气泵3抽吸空气，具有空气质量监测操作方便，空气采样量可控，可连续采样和连续监测，监测信息易收集和提高空气质量监测效率的技术效果。
现有技术中使用的空气质量监测设备，一般不设置进气装置1和加热组件11，而且也很少设置气泵3，只设置空气监测装置2对空气质量进行监测，这样的监测方式监测效率低，空气监测装置2内部的空气进入量较少，且进气不连续，导致对空气的监测结果不精准、模糊的现象，这样会影响对空气质量的评判结果。本申请设置进气装置1、加热组件11和气泵3，通过控制装置4控制运行和收集空气质量监测结果。具体地，通过气泵3抽吸空气，空气依次进入到进气装置1和空气监测装置2内，进入空气监测装置2的空气为热空气，这样容易对空气质量进行监测，提高监测精准度，气泵3的进气量可调节，通过使用气泵3，增大空气监测装置2内部的空气进入量，使得空气可以持续进入，从而提高了空气质量监测的精准度，便于后期对空气质量监测结果的分析和判断。
当空气监测装置2发生损坏或故障时，为了容易检修或观察空气监测装置2，则在一些实施例中，请参阅图3、图4、图12和图13，空气质量监测设备还包括第一安装支架5和第二安装支架6，进气装置1和空气监测装置2形成的核心单元连接于第一安装支架5上；控制装置4连接于第二安装支架6上，第一安装支架5与第二安装支架6转动配合连接，向远离第一安装支架5的方向转动第二安装支架6可逐渐露出空气监测装置2。通过转动第二安装支架6，空气监测装置2逐渐露出，待完全露出后，此时可对空气监测装置2进行检修或维护，当检修完毕后，可反向转动第二安装支架6使其复位，则可继续使用本设备，通过设置相互转动的第一安装支架5和第二安装支架6，解决了当空气监测装置2发生损坏或故障时，难以对空气监测装置2进行检修或维护、拆装困难的技术问题。
具体的，本申请的核心单元就是进气装置1和空气监测装置2，将其设置在第一安装支架5上，进气装置1和空气监测装置2之间相对固定，则不会影响两者使用。核心单元与控制装置4为电性连接，核心单元与气泵3之间通过管路13（气路或气管）连通。
通常情况下，第一安装支架5沿竖直方向设置，第二安装支架6沿水平方向设置，第一安装支架5的上端通过转轴64与第二安装支架6的一端转动连接，第一安装支架5与第二安装支架6之间的夹角约为90°，在第一安装支架5或第二安装支架6上设有用于限制第二安装支架6的转动角度的限位件65，即第二安装支架6转动后的状态或角度可通过该限位件65锁定，这样在后期对空气监测装置2维修时，第二安装支架6不发生转动，不影响检修操作。在本实施例中限位件65可选为螺栓或螺丝。
具体的，第二安装支架6为上下层叠的框架结构，控制装置4为一种电控板，通过如螺丝等连接件固定连接在第二安装支架6上，优选为固定连接在第二安装支架6的上端。
该框架结构包括与第一安装支架5铰接的电路板支架61、设置在电路板支架61上方的转接板62以及设置在转接板62上方的主控板63，控制装置4设置在主控板63的上端，主控板63与转接板62之间通过多个隔离柱66相隔设置，转接板62与电路板支架61之间也通过多个隔离柱66或其他形式的支柱等（竖向设置，相当于一种支柱）相隔设置，因此电路板支架61、转接板62和主控板63共同形成了该框架结构。隔离柱66为双头PC板隔离柱。
为了使进气装置1可以对空气加热，而且最大限度保证加热后的空气温度在预设范围内（可在控制装置4上预设温度范围），则在一些实施例中，请参阅图3、图4和图14，进气装置1包括加热盒12，进气装置1的空腔设于加热盒12内部，加热盒12上设有连通加热盒12外部的进气口和出气口，加热盒12的出气口连通空气监测装置2的进气口，加热组件11设于空腔内，空气在空腔内被加热后通过加热盒12的出气口流入空气监测装置2。加热盒12内部空腔的空气被加热组件11加热后，从空气监测装置2的进气口流入到空气监测装置2内部，便于空气监测装置2对热空气的质量进行监测。
在本实施例中，加热盒12为一种呈长方体形状的盒体或箱体，其内部为中空，具有进气口和出气口，加热盒12的进气口用来使外部的空气进入到加热盒12内部，加热盒12的进气口处设有过滤网或防虫网，加热盒12的出气口与空气监测装置2的进气口连通。优选的，在加热盒12的外壁上包裹有隔热层，这样可以防止加热盒12温度过高，对其外部的部件产生热影响。

具体的，加热棒111呈棒状，插接在加热盒12内部，加热棒111上端与加热盒12的上端固定连接，加热棒111上的线束从加热盒12的上端引出、并与控制装置4电性连接。而温度传感器112也是插接在加热盒12内部，便于实时监测温度数据，并可将温度数据实时传递给控制装置4。
本实施例中的控制装置4还电性连接有显示器（在图中未示出），在显示器上可以观察到当前的空气温度数据，便于合理控制加热棒111的加热程度。该显示器还电性连接有报警器，若加热后的空气温度不在预设温度范围内，则控制装置4会向报警器发出指示，则报警器发出报警信号。

具体的，上述的第一颗粒物传感器21、过滤器22均可采用现有技术产品，相互之间通过管路13连通，其具体操作原理在此不再赘述。
为了使空气质量监测结果更加精准，则在一些实施例中，请参阅图5至图9，气室组件23包括基体231、多个形成于基体231上的半封闭的气室232以及设于基体231内且串联连通多个气室232的气流通道233，每个气室232内均密封设有传感器模块234，传感器模块234与气室232形成封闭腔室（即气室232的顶部封闭），传感器模块234适于监测封闭腔室内流通在气流通道233的空气的质量。

空气进入的最后一个气室232内设有PID传感器236，此气室232内不再设置其他种类的传感器模块234，通过PID传感器236可以更加灵敏的监测空气中挥发性有机化合物（VOC），PID传感器236与控制装置4电性连接，在控制装置4上可实时接收到空气中挥发性有机化合物的监测结果。在PID传感器236的上端设有PID压环237，PID压环237通过螺丝与基体231可拆卸连接，其目的是将PID传感器236压紧在气室232内部，起到固定PID传感器236的作用。
为了实现在气室组件23上进一步监测空气中的温度和湿度，则在一些实施例中，请参阅图8至图9，其中一个或多个气室232的底部具有开口238，开口238连通基体231的外部，开口238内设有与基体231密封连接的第一温湿度传感器239，第一温湿度传感器239适于监测封闭腔室内空气的温度和湿度。一般情况下，在一个气室232内部设置一个第一温湿度传感器239即可，这样可以判断流通在气室232内的空气的温度和湿度。
具体的，第一温湿度传感器239与控制装置4电性连接，并可实时向控制装置4发送空气温湿度数据信息，控制装置4可第一时间收到空气温湿度数据信息。当不需要使用第一温湿度传感器239时，可将其从开口238处拆卸下来，安装和拆卸操作比较容易，最后用密封板等密封件将该开口238密封即可。第一温湿度传感器239呈凸字型的平板状结构，通过多个螺丝等紧固件固定在气室232底部的凹槽内（凹槽开设在开口238的底部）。

气泵3设置在底板7底部，气泵3并联设置为两组，分别与气室组件23的气体出口连通，其中一个气泵3为备用。当一个气泵3无法运行或出现故障时，则启动另一个气泵3，另一个气泵3运行后可抽吸空气，实现了空气质量的不间断监测。
如图1和图15所示，壳体8位于底板7上端，包括连接于底板7的内壳81、连接于底板7的外壳82以及通过多个螺丝等连接件连接在外壳82上端的上盖83，内壳81位于外壳82内部，内壳81与外壳82间隔设置、内壳81与上盖83间隔设置，且在内壳81与外壳82之间、内壳81与上盖83之间形成隔热空腔，进而起到对空气监测装置2隔热的作用，防止壳体8外部的环境温度对空气监测装置2的空气质量监测产生影响，提高了空气监测的精准度。
本申请还包括光伏供电组件（在图中未示出），光伏供电组件包括依次电性连接的太阳能电池板、控制器和蓄电池，太阳能电池板设置在底板7的底端或壳体8外表面上，控制器和蓄电池设置在壳体8内部，控制器用于将太阳能转化为电能，蓄电池用于储存电能，并为上述负载（例如，加热组件11、气泵3等）供电。蓄电池与负载之间连接有控制装置4，通过控制装置4的控制，可实现对负载的自动供电。控制装置4上设有用于控制是否向负载供电的供电开关（在图中未示出），通过人工或自动操作该供电开关，就可以控制是否执行供电。
以上所述仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本申请的保护范围之内。
