Description

Technical Field

[0001] The utility model relates to a monitoring device, in particular to an air monitoring device with a protective structure. Background Art

[0002] When monitoring outdoor air, most of the air monitors installed outdoors are exposed to the outside. On rainy days, the monitors are easily wetted by rain, which will affect the service life of the monitors in the long run. For this reason, some manufacturers will install a top cover on the top of the monitor when installing the air monitor, and use the top cover to reduce the impact of rain on the monitor, as shown in the technology disclosed in the utility model patent with application number CN202122785886.3. However, this solution provides very limited protection for the monitor. Since the top cover is installed above the monitor, although it can block the rain falling from above, when it is windy and rainy, the rain will still hit the monitor directly from the side; if the length of the top cover is lengthened so that the monitor is wrapped inside the top cover, although it can play a good protective role at this time, it will also block the flowing air from contacting the monitor, and it will not have a good monitoring effect.

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] Example 1

[0031] This embodiment discloses an air monitoring device with a protective structure, which includes an air monitor 5 and a protective cover for protecting the air monitor 5. Specifically, Figure 1As shown, the protective cover includes a lower cover 3 and an upper cover 1 connected to the upper part of the lower cover 3 through a support column 2. The upper cover 1 and the lower cover 3 are both rectangular, and the sizes of the two are matched. The upper end of the upper cover 1 is closed and the lower end is open, while the lower cover 3 is a frame structure with openings on both the upper and lower ends. There are four support columns 2, which are respectively located at the four corners of the upper cover 1 and the lower cover 3, and are used to connect and support the upper cover 1 and the lower cover 3. Through the above structure, an air inlet 6 is formed between the lower cover 3 and the upper cover 1, and air can enter the interior of the protective cover through the air inlet 6; since the protective cover is rectangular, air can enter the protective cover from all sides.

[0032] In addition, if Figure 2 As shown, a deflector 4 is provided inside the protective cover. When set, the upper end of the deflector 4 is connected to the upper cover 1, and the lower end thereof extends to the inside of the lower cover 3. The air monitor 5 is installed inside the deflector 4, and the monitoring probe 51 of the air monitor 5 penetrates the bottom of the deflector 4 and extends to the bottom of the deflector 4. When specifically set, the panel covering the upper cover 1 is detachable to facilitate the installation of the air monitor 5.

[0033] The air deflector 4 has four side walls, and the four side walls correspond to the positions of the air inlet 6, that is, the air entering from the air inlet 6 will impact the side walls of the air deflector 4. In addition, the four side walls of the air deflector 4 are inclined from top to bottom toward the center of the air deflector 4, so that the air deflector 4 is in an inverted cone shape as a whole, so that the air blown in from the air inlet 6 will flow downward along the side walls of the air deflector 4 and move toward the center of the protective cover, so that the air can flow toward the monitoring probe 51.

[0034] An air vent 7 is formed between the side walls of the air deflector 4 and the lower cover 3 for air to flow downward, and the size of the air vent 7 is smaller than the size of the air inlet 6. Since the size of the air vent 7 is smaller than the size of the air inlet 6, when the air enters the protective cover from the air inlet 6, the air will flow through the air vent 7 at an accelerated speed, enter the bottom of the air deflector 4, and finally be discharged from the lower end opening of the lower cover 3, which can improve the fluidity of the air and ensure the monitoring effect.

[0035] like Figure 2 , 4 As shown, each side wall of the air guide cover 4 is formed with a first air guide portion 41 and a second air guide portion 42 connected to the lower end of the first air guide portion 41, and the inclination angle of the second air guide portion 42 is greater than the inclination angle of the first air guide portion 41. In addition, the lower end of the second air guide portion 42 is connected to a downwardly protruding air guide portion 43.

[0036] Through the above structure, after the air enters the protective cover, it will flow toward the monitoring probe 51 under the guidance of the first guide part 41 and the second guide part 42, ensuring that the monitoring probe 51 can monitor the flowing air in real time. In rainy weather, rainwater enters from the air inlet 6 under the action of wind, but will be blocked by the first guide part 41 and the second guide part 42. At this time, the rainwater flows downward along the first guide part 41 and the second guide part 42, and finally falls out of the protective cover under the guidance of the drainage part 43, preventing the rainwater from directly hitting the monitoring probe 51.

[0037] Example 2

[0038] like Figure 2 , 3 As shown, based on the embodiment 1, this embodiment is provided with a connecting sleeve 8 at the bottom of the air deflector 4, and the monitoring probe 51 passes through the connecting sleeve 8. Accordingly, a protective sleeve 10 is installed inside the lower cover 3 through a supporting structure, and the protective sleeve 10 is located below the monitoring probe 51.

[0039] Specifically, Figure 5 As shown, the support structure includes two support rods 9 relatively fixed on the inner wall of the lower cover 3 , and a flip ring 12 connected to the two support rods 9 via a universal rotating joint 11 ; the flip ring 12 can flip relative to the universal rotating joint 11 .

[0040] The protective sleeve 10 is a cylinder with one end open and the other end closed, and passes through the flip ring 12 . In addition, baffles 13 are provided at both ends of the protective sleeve 10 to prevent the protective sleeve 10 from falling out of the flip ring 12 .

[0041] In addition, the outer diameter of the protective sleeve 10 is smaller than the inner diameter of the flip ring 12, so the protective sleeve 10 can move up and down. In specific implementation, the connecting sleeve 8 can be provided with an external thread, and the inner wall of the open end of the protective sleeve 10 is provided with an internal thread, so the connecting sleeve 8 can be detachably connected to the protective sleeve 10 through the thread.

[0042] When the device is in normal use, the protective cover 10 is separated from the connecting sleeve 8, and the flip ring 12 is rotated so that the open end of the protective cover 10 faces downward. Under the action of the protective cover 10's own gravity, the protective cover 10 remains in a vertical state, and foreign matter such as rainwater and dust are not easy to enter the protective cover 10. When the device is not used for a long time, the flip ring 12 is rotated so that the open end of the protective cover 10 faces upward, and the protective cover 10 is pushed to move upward. During the upward movement of the protective cover 10, the monitoring probe 51 is inserted into it, and finally the protective cover 10 is screwed onto the connecting sleeve 8 to protect the monitoring probe 51.

[0043] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.

[0044] In addition, the above specific embodiments are exemplary, and those skilled in the art can come up with various solutions inspired by the disclosure of the utility model, and these solutions also belong to the disclosure scope of the utility model and fall within the protection scope of the utility model. Those skilled in the art should understand that the utility model specification and its drawings are illustrative and do not constitute a limitation of the claims. The protection scope of the utility model is defined by the claims and their equivalents.
