Description

Technical Field

[0001] The utility model relates to the technical field of air duct detectors, in particular to a novel air duct sensor airflow detection and drainage structure. Background Art

[0002] Currently, there are two types of conventional instruments for measuring airflow in confined spaces, such as air ducts. One approach is the pump-suction method, which uses an air pump to extract air from the space and then analyze it. However, this approach has several drawbacks. First, the high cost of air pumps makes them unsuitable for mass production, and commercial buildings cannot afford the high cost. Furthermore, commercial and industrial air conditioners may need to operate continuously for 24 hours, which greatly tests the lifespan and reliability of the air pumps.

[0003] The second solution is to use a physical drainage structure to create a probe tube with a middle partition, with an air inlet and outlet on the front and back. The airflow enters the probe tube from port A, encounters resistance and runs to the detector's measuring chamber, and then is discharged from the other port B. The air pressure on the windward side is greater than that on the leeward side. The pressure difference between the windward and leeward sides is used to achieve physical drainage to reach the internal space of the detector for detection and measurement. Its structure is shown in the attached figure. Figure 1 / 2. However, it also has its drawbacks. The manufacturing process of this structure is too complicated and the assembly convenience is poor. During production, it is necessary to manufacture a stretched circular tube (stretching die) with a spacer in the middle. Because it is a stretching die, the drainage holes need to be processed using drilling and milling equipment, and the ends of the drainage tubes need to be sealed with glue, which makes processing and installation particularly inconvenient. Therefore, those skilled in the art have provided a new air duct sensor airflow detection and drainage structure for solving the inconvenience of manufacturing and producing the existing air duct detector drainage structure. Utility Model Content

[0005] Preferably, a baffle is provided inside the half-tube A, and a slot is provided inside the half-tube B. The baffle and the slot are adapted to each other and are plugged and fastened to each other.

[0024] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.

[0025] Example

[0026] like Figures 1 and 2 As shown, it is a structural diagram of a detector in the prior art, and its specific structure and principle are not described in detail. The accompanying drawings are only used to better illustrate the problems of the prior art and to compare with the technical solution of the present utility model;

[0027] like Figures 3 to 10 As shown, it is a novel air flow detection and drainage structure of an air duct sensor provided in this embodiment, including a tube body 1. The front end of the tube body 1 is connected to the sensor in the detector. The tube body 1 is composed of a half tube A2 and a half tube B3. The half tube A2 and the half tube B3 are connected together by a clip-on connection. Moreover, the rear ends of the half tube A2 and the half tube B3 are tightly clamped by an end cap 4 after they are clipped together. At the same time, the end cap 4 is also connected to the half tube A2 and the half tube B3 in the form of a clip-on connection, that is, the half tube A2, the half tube B3 and the end cap 4 are clipped and fixed to each other to form the entire tube body 1 structure. The entire structure is a split type, and each part can be manufactured separately, with a simple process. At the same time, its assembly is also very convenient, and installation is convenient, which is conducive to mass production, thereby solving the problem of inconvenient manufacturing and production of the drainage structure in the existing air duct detector;

[0028] Specifically, a baffle 21 is provided inside the half-tube A2 to block airflow. Correspondingly, a slot 31 is provided inside the half-tube B3. The baffle 21 fits in the slot 31 and can be plugged and fastened to each other. When the half-tubes A2 and B3 are engaged together, the entire tube body 1 can be divided into upper and lower parts, thereby blocking airflow.

[0029] The side where half-tube A2 and half-tube B3 engage with each other is provided with a plurality of equally spaced engagement points 23. At the same time, corresponding engagement grooves 33 are provided on half-tube B3, allowing the two to engage with each other, thereby tightly clamping half-tube A2 and half-tube B3. Furthermore, to enhance the sealing effect, a protruding plate 22 is provided between the engagement points 23 on half-tube A2, and a corresponding groove 32 is provided on half-tube B3, with the protruding plate 22 and the groove 32 engaging with each other.

[0030] Half holes A24 are provided on the rear side wall of half-tube A2, located on both the upper and lower sides of baffle 21. Similarly, half holes B34 are provided on the rear side wall of half-tube B3. Half holes A24 and B34 combine to form two upper and lower air ports. External gas enters from the bottom air port, and under the blocking effect of baffle 21, it moves toward the front end and passes through the sensor, which then enables measurement. After passing through the sensor, the gas flows from above the baffle 21 and is discharged from the upper air port, realizing gas circulation.

[0031] The rear ends of both half-tube A2 and half-tube B3 are provided with a through groove 5, and after half-tube A2 and half-tube B3 are engaged, two identical limit grooves 6 are formed at the rear ends thereof, and the through groove 5 is engaged with the end cap 4. Two clamping plates 42 are provided in the end cap 4, and the clamping plates 42 can be engaged with the through groove 5, so that after the end cap 4 is installed, it plays the role of a clamp and will not fall off. It can be installed stably and is very convenient. A limit strip 41 is also provided in the end cap 4, which is adapted to the limit groove 6. The limit strip 41 can provide convenience when installing the end cap 4. When installing it, first match the limit strip 41 with the limit groove 6, and then push the end cap 4 toward the front end of the tube body 1 with force. At this time, the clamping plate 42 will be stuck in the through groove 5, and the limit groove 6 plays the role of a guide rail, which can improve the convenience of installing the end cap 4.

[0032] The drainage structure of the present invention is formed by the mutual clamping of the half-tube A2 and the half-tube B3 of the built-in baffle 21 and the end cap 4. Its structural design is ingenious, the production and assembly are convenient, the integrity is good, no glue is required, and it is convenient for mass production. It solves the problem of the inconvenience in manufacturing the drainage structure in the existing air duct detector, has good practicality and broad market prospects.

[0033] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making any creative efforts should fall within the scope of protection of the present invention.
