The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0018] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.
[0019] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.
[0020] like Figure 1 , Figure 2 and Figure 3 As shown, an indoor air quality automatic monitor of the utility model includes an air monitor 9, a bottom plate 1 is installed on the bottom surface of the air monitor 9, half shells 2 are provided on both sides of the air monitor 9, the two half shells 2 are combined to form a protective shell covering the air monitor 9, and support strips 3 with a plurality of strip structures are protruded on the opposite sides of the half shells 2, arc grooves 11 are provided on the top surfaces of the half shells 2, and the two arc grooves 11 are combined to form a through hole, and the air inlet pipe 7 on the air monitor 9 is arranged to pass through the through hole, and a sealing sleeve 5 is installed on the air inlet pipe 7 to seal the air inlet pipe 7 and synchronously fix the half shells 2.
[0021] In this embodiment, positioning grooves 8 are vertically provided on both sides of the intake pipe 7, and positioning rods 12 are installed on the inner ring surface of the arc groove 11 opposite to the positioning groove 8. The positioning rods 12 are inserted into the positioning grooves 8, and the outer side surfaces of the positioning rods 12 are flush with the outer ring surface of the intake pipe 7. The outer ring surface of the intake pipe 7 is provided with an external thread, and the inner ring surface of the sealing sleeve 5 is provided with an internal thread. The sealing sleeve 5 is meshed with the external thread on the intake pipe 7 through the internal thread, and the outer ring surface of the sealing sleeve 5 is provided with an air inlet 6.
[0022] In this embodiment, the lower ends of the half shells 2 are fixedly connected to the bottom plate 1 via torsion spring hinges.
[0023] In this embodiment, the half shells 2 are made of plastic material, and grooves are provided in the front of the half shells 2. Transparent silicone plates 4 are installed in the grooves. The transparent silicone plates 4 are set against each other. The content displayed on the air monitor can be clearly seen through the transparent silicone plates, and the buttons on the air monitor can be touched by squeezing the transparent silicone plates, which facilitates the operation of the air monitor.
[0024] In this embodiment, the top surface of the positioning rod 12 is flush with the top surface of the air intake pipe 7, so that the sealing sleeve can move up and down along the air intake pipe without being blocked by the positioning rod.
[0025] In this embodiment, a rubber block is embedded on the outer ring surface of the air inlet pipe 7, and the outer side surface of the rubber block abuts against the open end surface inside the air inlet 6, thereby increasing the sealing of the air inlet and preventing the entry of outside air.
[0026] When not in use, Figure 1 As described above, the air monitor is covered by the bottom plate and the half shell, thereby effectively protecting the air monitor and avoiding external impacts. After falling, it is in direct contact with the half shell or the bottom plate, reducing the probability of damage.
[0027] When performing handheld monitoring, the sealing sleeve can be rotated to move upward along the air inlet pipe, but there is no need to remove the sealing sleeve from the air inlet pipe until the air inlet port is located at the upper end of the air inlet pipe, so that the air inlet port is connected with the air inlet pipe. At this time, the transparent silicone plate can be directly squeezed to complete the operation of the air monitor. In this state, the sealing sleeve still presses the positioning rod, so that the half shell cannot be opened outward;
[0028] When performing placement-type monitoring, the sealing sleeve can be directly removed. After the obstruction of the sealing sleeve is lost, the torsion of the torsion spring hinge can automatically drive the half shell to open outward until the bottom surface of the support bar is flush with the bottom surface of the bottom plate. The contact area is increased by the half shell and the support bar, so that the device can be directly placed on any plane. When monitoring the cabinet, the cabinet door can be opened and the device can be placed. After starting, the cabinet door can be closed immediately to ensure that the gas is not exposed, thereby improving the monitoring quality and increasing the adaptability of use.
[0029] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
