Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, specifically to a floor diffuser. Background Technology

[0002] Floor diffusers utilize a sandwich floor airflow system for heat dissipation. They are primarily suitable for situations requiring enhanced airflow convection in occupant areas, where airflow convection or upward airflow may be caused by people, machines, or electrical equipment. Floor-to-ceiling airflow is increasingly being used in rooms employing computers and other electronic instruments, allowing for the targeted and rapid elimination of localized heat loads.

[0003] Currently, floor diffusers on the market are generally expensive, time-consuming and labor-intensive to install, easily wasting a lot of manpower and money. In addition, the airflow direction of the diffuser is fixed, and the noise is loud, which is inconvenient when used in some special occasions. Therefore, improvements are needed. Utility Model Content

[0004] This utility model proposes a floor diffuser, which solves the problems in related technologies.

[0005] The technical solution of this utility model is as follows: A floor diffuser includes a housing and a cover plate. An air inlet pipe is fixedly connected through and to the side of the housing. A sliding rod is slidably connected through and to the side of the housing. A pressure plate and a fastening ring are fixedly connected to both ends of the sliding rod, respectively. A compression spring is sleeved on the surface of the sliding rod. A retaining ring is fixedly connected inside the housing. An adjustable diffuser mechanism is provided inside the housing. The adjustable diffuser mechanism includes a vertical rod. A support shell is fixedly connected to the surface of the vertical rod. A dust collection hopper is fixedly connected to the bottom of the vertical rod. A rotating block is rotatably connected to the top of the support shell. A first fan blade is fixedly connected to the surface of the rotating block. A second fan blade is rotatably connected to the surface of the rotating block. A support ring is fixedly connected to the top of the support shell. A compression mechanism is provided on the side of the vertical rod.

[0006] Optionally, the two ends of the compression spring are fixedly connected to the pressure plate and the housing, respectively. The end of the fastening ring away from the slide rod is initially in contact with the surface of the support housing. The compression spring ensures that the fastening ring is always in contact with the support housing.

[0007] Optionally, the surface of the support shell is provided with grooves, and the side of the fastening ring away from the slide rod is provided with teeth corresponding to the grooves on the surface of the support shell. The teeth on the side of the fastening ring cooperate with the grooves on the surface of the support shell to limit the position of the support shell.

[0008] Optionally, the surface of the rotating block is provided with anti-slip texture. The second fan blade is fixedly connected to the support ring. The first fan blade can be rotated by manually rotating the rotating block, while the second fan blade will not rotate due to the restriction of the support ring.

[0009] Optionally, the top of the retaining ring is initially in contact with the bottom of the support ring, and the bottom of the cover plate is initially in contact with the top of the support ring. The retaining ring provides support for the support ring, and the support ring provides support for the cover plate.

[0010] Optionally, the compression mechanism includes a pressure chamber and a compression block. The pressure chamber is fixedly connected to the side of the vertical rod. An air bladder is provided at one end of the pressure chamber. A piston rod is slidably connected to the piston inside the other end of the pressure chamber. A compression block is fixedly connected to the bottom of the piston rod. The compression block is fixedly connected to the surface of the rotating block.

[0011] Optionally, the airbag is initially inflated, and the end of the airbag away from the pressure chamber is close to the surface of the rotating block. When the rotating block rotates, it will cause the compression block to squeeze the airbag. The airbag is squeezed and the air pressure inside it will enter the pressure chamber and push the piston rod to move downward.

[0012] Optionally, the compression blocks are configured in three groups, and the compression blocks are generally in the shape of a frustum. The downward movement of the frustum-shaped compression blocks can compress the dust and lint in the dust collection hopper.

[0013] The working principle and beneficial effects of this utility model are as follows:

[0014] 1. This utility model is equipped with an adjustable diffuser mechanism, which allows the support shell, cover plate and other structures to be installed by cooperating with components such as fastening rings and retaining rings. The installation is simple, time-saving and labor-saving. When it is necessary to change the airflow direction, rotating the rotating block can drive the first blade to rotate. The change in the angle between the first blade and the second blade changes the airflow direction to adapt to the needs of different scenarios.

[0015] 2. In this utility model, by setting up a compression mechanism, during the process of rotating the rotating block driving the first blade plate to rotate, the compression block will also move downward repeatedly through the cooperation of components such as the extrusion block, air bag, and air pressure chamber to compress the dust and lint in the dust collection hopper, so that the dust and lint are compacted and prevented from flying when the airflow passes through.

[0028] Example 1

[0029] Reference Figures 1-6 This is the first embodiment of the present invention, which proposes a floor diffuser, including a housing 1 and a cover plate 8. An air inlet pipe 2 is fixedly connected through and to the side of the housing 1, and a slide rod 3 is slidably connected through and to the side of the housing 1. A pressure plate 4 and a fastening ring 5 are fixedly connected to both ends of the slide rod 3, respectively. A compression spring 6 is sleeved on the surface of the slide rod 3. A retaining ring 7 is fixedly connected inside the housing 1. An adjustable diffuser mechanism 9 is provided inside the housing 1. The adjustable diffuser mechanism 9 includes a vertical rod 91, and a support shell 92 is fixedly connected to the surface of the vertical rod 91. Both ends of the compression spring 6 are fixedly connected to the pressure plate 4 and the housing 1, respectively. The end of the fastening ring 5 away from the slide rod 3 is initially in contact with the surface of the support shell 92. The compression spring 6 ensures that the fastening ring 5 is always in contact with the support shell 92. The surface of the support shell 92 has grooves, and the side of the fastening ring 5 away from the slide rod 3 has teeth corresponding to the grooves on the surface of the support shell 92. The side teeth mesh with the grooves on the surface of the support shell 92 to limit the position of the support shell 92. The bottom of the vertical rod 91 is fixedly connected to the dust collection hopper 93. The top of the support shell 92 is rotatably connected to the rotating block 94. The surface of the rotating block 94 is fixedly connected to the first fan blade 95, and the surface of the rotating block 94 is rotatably connected to the second fan blade 96. The surface of the rotating block 94 is provided with anti-slip texture. The second fan blade 96 is fixedly connected to the support ring 97. By manually rotating the rotating block 94, the first fan blade 95 can be rotated, while the second fan blade 96 will not rotate under the restriction of the support ring 97. The top of the support shell 92 is fixedly connected to the support ring 97. The top of the retaining ring 7 is initially in contact with the bottom of the support ring 97. The bottom of the cover plate 8 is initially in contact with the top of the support ring 97. The retaining ring 7 provides support for the support ring 97, and the support ring 97 provides support for the cover plate 8. The side of the vertical rod 91 is provided with a compression mechanism 10.

[0030] In this embodiment, during installation, the pressure plate 4 pulls the slide rod 3 outward, causing the fastening ring 5 to move. The compression spring 6 is stretched, allowing the support shell 92 to be placed into the housing 1. The retaining ring 7 provides support for the support ring 97. When the pressure plate 4 and slide rod 3 are released, the compression spring 6 rebounds, causing the pressure plate 4 and slide rod 3 to move in the opposite direction to return to their original positions. At this time, the teeth on the side of the fastening ring 5 engage with the grooves on the surface of the support shell 92, limiting the position of the support shell 92. The overall installation is simple, saving time and effort. Connecting the air outlet duct of the air conditioning equipment to the air inlet duct 2 ensures airflow. The air enters through the inlet duct 2 and is blown out from the ground under the guidance of the first blade 95 and the second blade 96. Dust and lint enter the dust collection hopper 93 for collection. When it is necessary to change the airflow direction, the cover plate 8 is removed and the rotating block 94 is manually rotated. The rotation of the rotating block 94 can drive the first blade 95 to rotate, while the second blade 96 will not rotate due to the restriction of the support ring 97. The change in the angle between the first blade 95 and the second blade 96 changes the airflow direction to adapt to the needs of different scenarios.

[0031] Example 2

[0032] Reference Figures 1-6 This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: the compression mechanism 10 includes a pressure chamber 101 and a compression block 105. The pressure chamber 101 is fixedly connected to the side of the vertical rod 91. An air bladder 102 is provided at one end of the pressure chamber 101. A piston rod 103 is slidably connected to the piston inside the other end of the pressure chamber 101. A compression block 104 is fixedly connected to the bottom of the piston rod 103. The compression block 105 is fixedly connected to the surface of the rotating block 94. The air bladder 102 is initially in an inflated state, and the end of the air bladder 102 away from the pressure chamber 101 is close to the surface of the rotating block 94. When the rotating block 94 rotates, it will drive the compression block 105 to squeeze the air bladder 102. The air pressure inside the air bladder 102 will enter the pressure chamber 101 and push the piston rod 103 downward. There are three sets of compression blocks 105. The compression block 104 is frustum-shaped. The downward movement of the frustum-shaped compression block 104 can compress the dust and lint in the dust collection hopper 93.

[0033] Compared to Embodiment 1, further, when the rotating block 94 is manually rotated, the rotation of the rotating block 94 drives the first fan blade 95 to rotate for adjustment. The rotation of the rotating block 94 also drives the compression block 105 to compress the airbag 102. The airbag 102 is compressed, and the air pressure inside it enters the air pressure chamber 101, pushing the piston rod 103 to move downward. The downward movement of the piston rod 103 drives the compression block 104 to move downward. The downward movement of the frustum-shaped compression block 104 can compress the dust and lint in the dust collection hopper 93. When the airbag 102 rebounds, the air pressure drives the piston rod 103 and the compression block 104 to move upward to restore their original position.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
