Description

Technical Field

[0001] The utility model belongs to the technical field of air quality detection, and specifically relates to a multi-angle air quality detector. Background Art

[0002] People pay more and more attention to air quality year by year, and gradually realize the great impact of air quality on people's health. Therefore, a large number of air quality detection devices and purification equipment have entered our lives.

[0003] When using an outdoor air quality detector, external air is sucked into the detector. During the inhalation, large foreign particles in the air will enter, which will then affect the internal equipment. Therefore, a corresponding dust net will be installed at the air inlet. However, when encountering windy and rainy weather, rain will enter the instrument through the air inlet. The dust net alone cannot effectively block the external rain. If rain enters the instrument, it will cause damage to the instrument. At the same time, if the unidirectional wind force is too strong, convection may form between multiple air inlets, causing the external wind to be discharged from the air inlet on the other side, resulting in incorrect detection data. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a multi-angle air quality detector, which can automatically close the air inlet according to the wind direction when encountering windy and rainy weather to prevent rainwater from entering the instrument along the wind direction and ensure the normal operation of the instrument.

DETAILED DESCRIPTION

[0020] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0021] Please refer to Figure 1 -As shown in the figure, a multi-angle air quality detector includes a chassis 1, a vertical tube 2 is vertically arranged on the upper surface of the chassis 1, a lifting rod 3 is installed on the top of the vertical tube 2, the lifting rod 3 can slide vertically to adjust the overall height of the equipment, and the lifting rod 3 is kept stable by the pins and the holes on the surface of the lifting rod 3. A control box 5 is fixed on the top of the lifting rod 3, and a power supply, a controller, a detector, etc. are arranged inside the control box 5. An air intake pipe 6 is vertically arranged at the center of the top of the control box 5. The air intake pipe 6 is connected to the fan inside the control box 5 and passes into the detector. The top of the air intake pipe 6 is provided with multi-directional The suction head 8, the air intake pipe 6 and the multi-directional suction head 8 are internally connected, and the surface of the multi-directional suction head 8 is evenly provided with air inlets 9, so as to realize multi-angle and multi-directional suction detection. A dustproof net 10 is arranged on the inner side of the air inlet 9, which can block and control medium and large-sized particles or foreign objects. The inner wall of the multi-directional suction head 8 is evenly provided with slide grooves 11, and multiple slide grooves 11 are respectively placed above multiple dustproof nets 10. A sealing slide plate 12 is vertically slidably installed on the inner side of the slide groove 11. The sealing slide plate 12 is controlled to move downward to seal the bottom of the air inlet 9 or reduce the opening size of the air inlet 9 to control the air intake volume.

[0022] Please refer to Figure 2 As shown, a hemispherical seat 13 is installed on the upper surface of the multi-directional suction head 8, and a mounting shaft 14 vertically penetrates the center of the hemispherical seat 13. The mounting shaft 14 can be offset in any direction along with the hemispherical seat 13. A swing cylinder 15 is arranged on the top of the mounting shaft 14. The inside of the swing cylinder 15 is hollow and has a light weight so that it can swing along with the wind direction. The swing cylinder 15 is placed at the center position above the outer side of the multi-directional suction head 8. A control panel 16 is arranged at the bottom of the mounting shaft 14. The control panel 16 is placed above the inside of the multi-directional suction head 8. When the swing cylinder 15 deviates to one side, the control panel 16 deviates to the other side.

[0023] Among them, the side surface of the control panel 16 is arc-shaped, and the arc-shaped structure can reduce the friction with the baffle 19 when swinging. Lower extension seats 17 are evenly arranged on the upper part of the multi-directional suction head 8, and multiple lower extension seats 17 correspond to the air inlet 9 one by one. A sliding rod 18 slides through the inner side of the lower extension seat 17, and the sliding rod 18 slides horizontally. A baffle 19 is arranged on the side where the multiple sliding rods 18 are close to each other, and the side surfaces of the multiple baffles 19 facing away from the sliding rod 18 are in contact with the arc of the side surface of the control panel 16. When the swing cylinder 15 at the top deviates to one side, the corresponding baffle 19 on the other side can be squeezed.

[0024] Please refer to Figure 2 and Figure 3 As shown, a spring 20 is sleeved on the surface of the slide rod 18, and the spring 20 is placed between the baffle 19 and the lower extension seat 17. The elastic force of the spring 20 can be used to push the control panel 16 to the center of the multi-directional suction head 8 in windless weather to keep the swing cylinder 15 in a vertical state.

[0025] Among them, the end of the sliding rod 18 away from the baffle 19 is hinged with a connecting rod 21, and the end of the connecting rod 21 away from the sliding rod 18 is hinged at the top of the sealing slide 12. The connection direction of the connecting rod 21 ensures that when the sliding rod 18 moves away from the center, it can drive the sealing slide 12 at the corresponding position to move downward.

[0026] Please refer to Figure 1 As shown, a wind vane 7 is provided on one side of the top of the control box 5, a display screen 4 is fixed on the front side of the lifting rod 3, and the display screen 4 is placed below the control box 5 to display various parameters of the air in real time.

[0027] The working principle of the utility model is as follows: the overall height of the multi-directional suction head 8 can be controlled by lifting and lowering the lifting rod 3, and its height can be kept stable. Due to the presence of multiple springs 20, multiple baffles 19 all have a force toward the center position, and pull the sealing slide plate 12 to be placed at the top, and place the control disk 16 at the set center position. The mounting shaft 14 and the swing cylinder 15 are in a vertical state. When the wind force on one side is too large, the swing cylinder 15 can be blown to tilt it, so that the control disk 16 is offset to the other side to push the baffle 19 to move toward the wind direction, and then the sealing slide plate 12 can be driven downward by the cooperation of the slide bar 18 and the connecting rod 21 to block the air inlet 9 to reduce the wind force. At this time, the spring 20 close to the wind direction side is squeezed and stored. When the wind force decreases, the stored force of the spring 20 can be used to push the control disk 16 back to keep the swing cylinder 15 back to the vertical state.

[0028] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
