Description

Technical Field

[0001] The utility model relates to the technical field of air circulation, in particular to an indoor air circulation device. Background Art

[0002] Indoor air circulation refers to a measure of keeping the indoor air flowing through various means to improve air quality, enhance comfort and promote health. Good indoor air circulation is crucial for maintaining a healthy living and working environment. Among the existing circulation devices, the circulation fan is the most cost-effective one.

[0003] Since the main working part of the circulation fan is the head, the center of gravity of the whole device is relatively high. When an indoor person accidentally touches the circulation device, the circulation device will tip over. At this time, the circulation device may be damaged, which will cause property losses to the user and a bad experience for the user.

[0004] To solve the above technical problems, we designed an indoor air circulation device that prevents tipping. Summary of the Utility Model

[0005] In order to overcome the disadvantage that the center of gravity of the air circulation fan is relatively high and it will tip over when touched, the technical problem of the utility model is: to provide a circulation fan for indoor use that prevents tipping.

[0006] The technical implementation scheme of the utility model is: an indoor air circulation device, which includes a chassis. A fan is rotatably connected to the top end of the chassis. Four cylinders are evenly fixedly connected to the side of the chassis far from the fan. An arc-shaped plate is fixedly connected to the outer side of the telescopic rod of the cylinder. The arc-shaped plate contacts the chassis. A limiting rod is fixedly connected to the inner side of the arc-shaped plate. The limiting rod is slidably connected to the side of the chassis far from the fan. Four symmetric threaded rods are evenly fixedly connected to the side of the chassis close to the fan. A plurality of counterweight pieces are slidably connected to the threaded rods. A threaded cap is threadedly connected to the threaded rods. The threaded cap contacts the counterweight pieces.

[0007] More preferably, it further includes a rounded corner frame. The rounded corner frame is slidably connected to the side of the chassis close to the fan. A return spring is connected between the rounded corner frame and the chassis. A connecting frame is fixedly connected to the side of the rounded corner frame far from the chassis. A suction cup is fixedly connected to the side of the connecting frame far from the chassis. Symmetric connecting plates are fixedly connected to the side of the symmetric limiting rods close to the rounded corner frame. The connecting plates are slidably connected to the chassis. The connecting plates are located on the side of the connecting frame close to the rounded corner frame. The connecting frame contacts the connecting plates.

[0008] More preferably, in order to ensure that the connecting frame can descend normally, protrusions are provided on the side of the connecting frame close to the rounded corner frame. Through the contact between these protrusions and the connecting plates, the normal lifting of the connecting frame is realized.

[0009] More preferably, it further includes a water tank. The water tank is fixedly connected to the side of the chassis away from the counterweight. A water pump is fixedly connected to the side of the water tank close to the fan. The water inlet of the water pump is communicated with the water tank. A connecting pipe is fixedly connected to the side of the water pump close to the fan. The side of the connecting pipe away from the fan is communicated with the water outlet of the water pump. A nozzle is fixedly connected to the side of the fan close to the water tank. A connecting pipe is fixedly connected to the side of the nozzle close to the water tank. The connecting pipe is communicated with the nozzle.

[0010] More preferably, in order to ensure that the connecting pipe can rotate with the nozzle, we set the material of the connecting pipe to be rubber, so that the connecting pipe can rotate normally with the nozzle.

[0011] More preferably, in order to ensure that the liquid in the water tank will not be missing and to ensure the humidifying effect of the entire device, we set an inlet on the lower rear side of the water tank, so that it can be ensured that there is no water shortage in the water tank.

[0012] The beneficial effects are as follows: When there is a local overheating or overcooling situation in the space where the user lives, or when there is poor ventilation indoors, resulting in a difference between indoor and outdoor air, the user needs to start the air circulation device at this time. Through the operation of the circulation device, the indoor air is circulated and mixed evenly to ensure the user's living experience. Because the center of gravity of the floor-standing circulation device is relatively high, when an indoor person touches the circulation device, it may cause the circulation device to tip over, which will cause property losses and affect the user's living experience. At this time, we increase the stability of the circulation device by extending the arc-shaped plate to increase the chassis area. Secondly, we also change the center of gravity position of the circulation device and increase the chassis weight by installing multiple counterweights and fixing the counterweights to avoid the tipping over of the circulation device.

[0013] To further increase the stability of the entire device, we also lower the connecting frame and make the suction cup more firmly adsorbed on the ground, so that the circulation device becomes an integral part with the ground. And because of the installation position of the suction cup, the circulation device can further reduce the risk of shaking and tipping over. And through the linkage between the connecting frame and the connecting plate, the load and power consumption of the circulation device are also reduced.

[0014] To increase the linkage between the connecting plate and the connecting frame, we set a raised block at the upper end of the connecting frame. In this way, when the connecting plate moves, the connecting frame will also descend at the same time, which further reduces the complexity of the entire device.

[0015] When the user needs to change the dryness of the surrounding environment and the dryness of their own skin, they can start the water pump. Through the spraying of the nozzle and the spreading of the circulation device, the dryness and humidity of the surrounding environment can be changed. After achieving the desired effect, the water pump can be stopped from operating.

[0016] To ensure the spreading effect and that the connecting pipe can rotate with the nozzle, we set the material of the connecting pipe to rubber. In this way, when the connecting pipe twists, water interruption will not occur at the nozzle.

[0017] To ensure that there is no pause during humidification, we set a water inlet at the rear side of the water tank. In this way, the user can always replenish the liquid in the water tank and ensure the continuous operation of this function. Description of the Drawings

Detailed Embodiments

[0027] The following describes the embodiments of the present utility model in detail with reference to the drawings.

[0028] Embodiment 1: An indoor air circulation device, as Figures 1-3As shown in the figure, it includes a chassis 1. A fan 2 is rotatably connected to the top end of the chassis 1. Four cylinders 4 are fixedly connected to the lower end of the chassis 1 circumferentially and evenly. An arc-shaped plate 3 is fixedly connected to the outer side of the telescopic rod of the cylinder 4. The arc-shaped plate 3 contacts the lower end of the chassis 1. Symmetric limiting rods 301 are fixedly connected to the inner side of the arc-shaped plate 3. The limiting rods 301 are slidably connected to the lower end of the chassis 1. Four symmetric threaded rods 5 are fixedly connected to the upper end of the chassis 1 evenly. A plurality of counterweight pieces 6 are slidably connected to the threaded rods 5. A threaded cap 7 is threadedly connected to the upper part of the threaded rod 5. The threaded cap 7 contacts the counterweight piece 6.

[0029] When using the device as needed, first unscrew the threaded cap 7 on the threaded rod 5. Then, according to the needs of the user, take a certain number of counterweight pieces 6. Then put the counterweight pieces 6 on the threaded rod 5. The counterweight pieces 6 will slide down from the threaded rod 5. Then thread the threaded cap 7 onto the threaded rod 5. Then tighten the threaded cap 7. Finally, start the fan 2, and then start the cylinder 4. The telescopic rod of the cylinder 4 drives the arc-shaped plate 3 and the limiting rod 301 to move outward. After extending a fixed distance, the cylinder 4 stops operating. After improving the air, the fan 2 can be stopped. When the user needs to put away the device, start the cylinder 4 to operate in the reverse direction. The cylinder 4 drives the arc-shaped plate 3 and the limiting rod 301 to contract together. When the arc-shaped plate 3 contacts the chassis 1, the cylinder 4 stops operating.

[0030] Embodiment 2: On the basis of Embodiment 1, as Figures 4-6 shown, it further includes a rounded corner frame 11. The rounded corner frame 11 is slidably connected to the middle of the upper end of the chassis 1. A return spring 12 is connected between the rounded corner frame 11 and the chassis 1. A connecting frame 9 is fixedly connected to the lower end of the rounded corner frame 11. A suction cup 10 is fixedly connected to the lower end of the connecting frame 9. Symmetric connecting plates 8 are fixedly connected to the inner sides of the symmetric limiting rods 301. The connecting plates 8 are slidably connected to the lower end of the chassis 1. The connecting plates 8 are located above the connecting frame 9. The connecting frame 9 contacts the connecting plates 8.

[0031] When the cylinder 4 starts to extend, the limiting rods 301 on the left and right sides will drive the connecting plates 8 to move to the left and right sides together. When the connecting plates 8 move, the connecting plates 8 will squeeze the connecting frame 9 downward. While the connecting frame 9 descends, it will also drive the rounded corner frame 11 to descend together. At this time, the return spring 12 located below the rounded corner frame 11 is compressed. Also, because the suction cup 10 is fixedly connected to the lower side of the connecting frame 9, the suction cup 10 will also descend together. And during the descending process, the suction cup 10 first contacts the ground, then the suction cup 10 is squeezed, and finally the suction cup 10 will be adsorbed on the ground. When the cylinder 4 starts to retract, the limiting rods 301 will also drive the connecting plates 8 to move to the left and right sides. When the connecting plates 8 no longer contact the connecting frame 9, the connecting frame 9 and the rounded corner frame 11 will move upward under the upward reset of the return spring 12 and stop at the uppermost side.

[0032] As Figure 5As shown, in order to ensure that the connecting frame 9 can descend normally, we have provided protrusions at the upper end of the connecting frame 9. Through the contact of these protrusions with the connecting plate 8, the normal lifting and lowering of the connecting frame 9 is achieved.

[0033] In order to ensure that the connecting frame 9 can descend normally, we have provided a protruding block on the connecting frame 9. Through the contact of the connecting plate 8 with the protruding block, and the connecting plate 8 can only move horizontally, and the connecting frame 9 can only move up and down, so the connecting plate 8 will squeeze the connecting frame 9 to the lower side.

[0034] As Figure 7 and Figure 8 shown, it also includes a water tank 13. The water tank 13 is fixedly connected to the upper side of the rear part of the chassis 1. A water pump 14 is fixedly connected to the upper end of the water tank 13. The water inlet of the water pump 14 is communicated with the water tank 13. A connecting pipe 15 is fixedly connected to the upper end of the water pump 14. The lower end of the connecting pipe 15 is communicated with the water outlet of the water pump 14. A nozzle 16 is fixedly connected to the rear end of the fan 2. The lower end of the nozzle 16 is fixedly connected to the connecting pipe 15. The upper end of the connecting pipe 15 is communicated with the nozzle 16.

[0035] In order to improve the air quality, when needed by the user, the water pump 14 can be started. The water pump 14 pumps out the liquid in the water tank 13 and transfers it to the nozzle 16 through the connecting pipe 15. Finally, the liquid is sprayed out from the nozzle 16. After meeting the needs of the user, the water pump 14 stops operating.

[0036] As Figure 8 shown, in order to ensure that the connecting pipe 15 can rotate with the nozzle 16, we set the material of the connecting pipe 15 to be rubber, so that the connecting pipe 15 can rotate normally with the nozzle 16.

[0037] In order to ensure that the connecting pipe 15 can rotate left and right with the nozzle 16, we set the material of the connecting pipe 15 to be rubber. In this way, during the left and right rotation process, the connecting pipe 15 will not lose its function and ensure that the liquid can flow normally.

[0038] As Figure 7 shown, to ensure that the liquid in the water tank 13 will not be missing and to ensure the humidifying effect of the entire device, we have provided a water inlet at the lower rear side of the water tank 13, so that it can be ensured that there will be no water shortage in the water tank 13.

[0039] In order to ensure the continuity of the humidifying effect, we have provided a water inlet at the rear end of the water tank 13, so that it can be ensured that there will always be sufficient liquid in the water tank 13 to ensure that the nozzle 16 can operate continuously.

[0040] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
