Description

Technical Field

[0001] This utility model relates to the field of air quality detection technology, and in particular to an indoor air quality detection device. Background Technology

[0002] "Indoor" primarily refers to living spaces. Indoor air pollution refers to the pollution of the indoor environment caused by various reasons, resulting in excessive levels of harmful substances that affect human health. Harmful substances include formaldehyde, benzene, ammonia, and radioactive radon. As pollution levels increase, it can lead to sub-health conditions and even threaten life. Therefore, it is usually necessary to conduct indoor air quality testing using air quality monitoring devices before moving in.

[0003] To address the issue of measurement errors caused by uneven indoor air quality, commercially available air quality testing devices, such as the multi-directional indoor air quality testing device disclosed in patent application CN202323542493.5, include: a content analysis component and two sets of air homogenization components. The content analysis component is used to detect the content of various components in the air. The air homogenization components include a central connecting sphere, an exhaust duct, and multiple suction ducts. The central connecting sphere has an air passage cavity inside and includes a mounting hemisphere and a connecting hemisphere. The exhaust duct is connected to the middle of the connecting hemisphere and communicates with the air passage cavity. One end of each of the multiple suction ducts is connected to the connecting hemisphere and communicates with the air passage cavity. The multiple suction ducts are evenly distributed around the circumference of the exhaust duct, with the ends of the multiple suction ducts away from the central connecting sphere facing different directions. An exhaust fan is installed inside the exhaust duct, which draws in indoor air through the suction ducts and then exhausts it through the exhaust duct. A preliminary detection module is also installed in the air passage cavity. The preliminary detection module and the exhaust fan are communicatively connected to the content analysis component.

[0004] The above-mentioned technical solutions still have some technical defects. For example, the two sets of air homogenization components are installed on the ground and on the ceiling respectively. The ground-mounted components are easily blocked by furniture and debris, affecting the suction efficiency; the ceiling-mounted components require climbing to install, which poses a safety hazard; the suction tube has a fixed direction, which does not fully sample the air in the corners of irregular rooms (such as L-shaped or polygonal ones), which may lead to incomplete circulation. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an indoor air quality detection device that can detect the average indoor air quality, ensuring detection accuracy while saving time and effort.

[0006] An indoor air quality detection device according to a first aspect of the present invention includes at least two sets of air homogenization component bodies. Each air homogenization component body includes a central connecting ball, an exhaust duct, and multiple suction ducts. The central connecting ball includes a mounting hemisphere and a connecting hemisphere connected to the mounting hemisphere. An air passage cavity is formed in the connecting hemisphere. The exhaust duct and the multiple suction ducts are respectively connected to the exhaust port and the air inlet of the air passage cavity. Each suction duct includes a universal bamboo joint tube and a suction nozzle. The two ends of the universal bamboo joint tube are respectively connected to the air inlet of the air passage cavity and the suction nozzle. Each air homogenization component body is connected to a wall surface.

[0007] The indoor air quality detection device according to the embodiments of this utility model has at least the following beneficial effects: by setting a suction tube composed of a universal bamboo joint tube and a suction nozzle, the suction tube can be bent at multiple angles to suction air from different directions.

Instead, it can be installed on the wall, which is convenient for installation and does not affect the suction efficiency. This allows the indoor air to reach a homogenized state more quickly, ensuring the accuracy of the detection and saving time and effort.

[0008] According to some embodiments of the present invention, the indoor air quality detection device further includes a content analysis component body, which is disposed at the center of the room.

[0009] According to some embodiments of the present invention, the exhaust duct is positioned toward the content analysis component body.

[0010] According to some embodiments of the present invention, an exhaust fan is connected to the exhaust duct.

[0011] According to some embodiments of the present invention, the exhaust duct includes an inner tube and an outer tube nested outside the inner tube. The inner tube is fixedly connected to the connecting hemisphere, the outer tube is slidably connected to the inner tube, and the exhaust fan is connected in the inner tube.

[0012] According to some embodiments of the present invention, a slider is connected to the inner wall of the outer tube, and a slide rail is correspondingly connected to the outer wall of the inner tube, and the slide rail is slidably connected to the slider.

[0013] According to some embodiments of the present invention, the diameter of the end of the outer tube away from the connecting hemisphere gradually decreases in the direction from near the connecting hemisphere to away from the connecting hemisphere.

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0023] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0025] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0026] refer to Figure 1 as well as Figure 2 As shown, the indoor air quality detection device according to an embodiment of the present invention includes at least two sets of air homogenization component bodies. Each air homogenization component body includes a central connecting ball, an exhaust duct, and multiple suction ducts. The central connecting ball includes a mounting hemisphere 110 and a connecting hemisphere 120 connected to the mounting hemisphere 110. An air passage cavity (not shown in the figure) is formed in the connecting hemisphere 120. The exhaust duct and multiple suction ducts are respectively connected to the exhaust port and air inlet of the air passage cavity. The suction duct includes a universal bamboo joint tube 310 and a suction nozzle 320. The two ends of the universal bamboo joint tube 310 are respectively connected to the air inlet of the air passage cavity and the suction nozzle 320. Each air homogenization component body is connected to the wall.

[0027] In practical use, the suction tube composed of the universal bamboo joint tube 310 and the suction nozzle 320 can be bent at multiple angles to suction air from different directions. This avoids the need for the air homogenization component to be installed at the top or bottom to suction air at different heights and positions. Instead, it can be installed on the wall, which is convenient for installation and does not affect the suction efficiency. This allows the indoor air to reach a homogenized state more quickly, ensuring the accuracy of the detection and saving time and effort.

[0028] Specifically, multiple sets of air homogenizing components are connected to different walls. When there are only two sets of air homogenizing components, they are placed on two opposite walls. The air intake of the suction nozzle 320 of one set of air homogenizing components is bent so that it is higher than the direction of the central connecting ball. The multiple suction nozzles of the other set of air homogenizing components are bent so that the air intake of the suction nozzle 320 is lower than the direction of the central connecting ball. When there are more than two air homogenizing components, the suction nozzles of two adjacent air homogenizing components are set to face opposite directions.

[0029] In some specific embodiments of this utility model, it may also have the following additional technical features: the indoor air quality detection device further includes a content analysis component body (not shown in the figure), which is located at the center of the room.

[0030] In some specific embodiments of this utility model, it may also have the following additional technical features: the exhaust duct is oriented toward the content analysis component body.

[0031] In some specific embodiments of this utility model, it may also have the following additional technical features: an exhaust fan 210 is connected in the exhaust duct.

[0032] With the above settings, the homogenized indoor air can be directly discharged toward the content analysis component, allowing the content analysis component to analyze the homogenized indoor air quality more quickly.

[0033] In some specific embodiments of this utility model, it may also have the following additional technical features: the exhaust duct includes an inner tube 220 and an outer tube 230 nested outside the inner tube 220, the inner tube 220 is fixedly connected to the connecting hemisphere 120, the outer tube 230 is slidably connected to the inner tube 220, and the exhaust fan 210 is connected in the inner tube 220.

[0034] In some specific embodiments of this utility model, it may also have the following additional technical features: a slider (not shown in the figure) is connected to the inner wall of the outer tube 230, and a slide rail (not shown in the figure) is correspondingly and compatiblely connected to the outer wall of the inner tube 220, and the slide rail and the slider are slidably connected.

[0035] In some specific embodiments of this utility model, it may also have the following additional technical features: the diameter of the end of the outer tube 230 away from the connecting hemisphere 120 gradually decreases in the direction from near the connecting hemisphere 120 to away from the connecting hemisphere 120. Specifically, the end of the outer tube 230 away from the connecting hemisphere 120 is the air outlet, that is, the diameter of the air outlet gradually decreases.

[0036] In some specific embodiments of this utility model, it may also have the following additional technical features: a return spring 240 is connected between the outer tube 230 and the connecting hemisphere 120.

[0037] With the above design, when the exhaust fan is working, the airflow in the inner tube 220 will pass through the outer tube 230 before being discharged. As the diameter of the air outlet of the outer tube 230 gradually decreases, the airflow will continuously impact the outer tube 230, thereby causing the outer tube 230 to overcome the elastic force of the return spring 240 and extend outward. This makes the length of the entire exhaust duct longer, resulting in a longer period of concentrated airflow. In addition, the narrowed air outlet design allows the initial velocity of the airflow ejected from the outlet to be higher, thus enabling it to concentrate and flow over a longer distance. This, in turn, drives the surrounding airflow during this distance, accelerating the uniformity of air throughout the room, making it suitable for use in large indoor spaces.

[0038] In some specific embodiments of this utility model, it may also have the following additional technical features: the suction nozzle 320 has a flared structure, and the smaller end of the suction nozzle 320 is connected to the universal bamboo tube 310.

[0039] Through the above design, the flared nozzle 320 can draw in a larger volume of air.

[0040] In some specific embodiments of this utility model, it may also have the following additional technical features: a dustproof net (not shown in the figure) is connected to the suction nozzle 320.

[0041] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
