[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. In the case of the housing assembly of this air purification device, when the anti-collision plate is impacted by an external force during daily use, the anti-collision plate will cause the moving plate to slide. Subsequently, the moving plate will cause the moving block to slide inside the strip groove and on the surface of the round rod. Then, the moving block will squeeze and compress the buffer spring. At this time, the anti-collision plate will cause the damping rod to retract inside the base. Subsequently, the anti-collision plate can squeeze and compress the return spring. The impact force can be buffered by the buffer spring and return spring, thereby reducing the damage to the housing and improving its service life.
[0013] 2. In the daily use of this air purification equipment's housing assembly, the operator activates the pneumatic cylinder, which causes the support frame to slide. Subsequently, the support frame drives the guide rod to slide inside the circular tube.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4This utility model provides a technical solution: a housing assembly for an air purification device, including a base 1. Four strip-shaped grooves 2 are circumferentially formed around the bottom of the base 1, and all grooves 2 are of the same size. A round rod 3 is fixedly installed inside each of the strip-shaped grooves 2. A movable block 4 is movably sleeved on the surface of each round rod 3. The inner surface of the movable block 4 and the outer surface of the round rod 3 are both smooth, allowing the movable block 4 to slide more smoothly on the surface of the round rod 3 and reducing the occurrence of jamming. A buffer spring 5 is fixedly installed on one side of each movable block 4. The inner surface of the movable block 4 is movably connected to the outer surface of the round rod 3. When the movable block 4 slides inside the strip groove 2 and on the surface of the round rod 3, it will squeeze and compress the buffer spring 5, thus buffering the impact force. A movable plate 6 is movably installed around the surface of the base 1. One side of the movable plate 6 passes through the base 1 and extends into the interior of the base 1. The bottom of the movable plate 6 is fixedly connected to the top of the movable block 4. Anti-collision plates 7 are fixedly installed on the other side of the movable plate 6. The outer surface of the movable plate 6 and the inner surface of the base 1 are both smooth. When the anti-collision plate 7 slides, it will cause the movable plate 6 to move. A damping rod 8 is movably mounted inside the base 1, and it has the function of compressing and contracting. One side of the damping rod 8 passes through the base 1 and is fixedly connected to one side of the anti-collision plate 7. The outer surface of the damping rod 8 and the inner surface of the base 1 are both smooth. When the anti-collision plate 7 slides, it will cause the damping rod 8 to contract and buffer inside the base 1. A return spring 9 is fixedly installed between the anti-collision plate 7 and the base 1, and the inner surface of the return spring 9 is movably connected to the outer surface of the damping rod 8. When the anti-collision plate 7 slides, it will cause the return spring 9 to slide, thereby mitigating the impact force. The base 1 has four circular tubes 10 fixedly installed around its interior. The number of circular tubes 10 is the same, and each circular tube 10 has a guide rod 11 movably installed inside its interior. The bottom of the guide rod 11 passes through the base 1 and extends to the bottom of the base 1. A support frame 12 is fixedly installed at the bottom of the guide rod 11. The support frame 12 is cross-shaped. When the support frame 12 slides, it will cause the guide rod 11 to slide inside the circular tube 10. Thus, the guide rod 11 and the support frame 12 can provide auxiliary support for the base 1, thereby improving its stability.
[0021] The outer surface of the circular tube 10 is provided with grooves 13, and sliders 14 are movably installed inside the grooves 13. One side of the slider 14 is fixedly connected to one side of the guide rod 11. When the guide rod 11 slides, it will drive the slider 14 to slide inside the groove 13. The design of the grooves 13 and sliders 14 makes the sliding of the guide rod 11 more stable. A pneumatic cylinder 15 is fixedly installed at the bottom of the base 1. The output end of the pneumatic cylinder 15 passes through the base 1 and is fixedly connected to the top of the support frame 12. When the pneumatic cylinder 15 is running, it will cause the support frame 12 to slide, thereby improving the adjustment efficiency. A housing 16 is fixedly installed on the top of the base 1. Air inlets 17 are opened at equal intervals at one end of the housing 16. The housing 16 can protect the parts of the equipment. The air that needs to be purified will enter through the air inlets 17. Inside the housing 16, a control panel 18 is fixedly installed at one end of the housing 16. A display screen 19 is fixedly installed at one end of the control panel 18. Operation buttons 20 are equidistantly installed at one end of the control panel 18. The device can be operated through the operation buttons 20. The display screen 19 can display the operation data for easy observation by the operator. Universal wheels 23 are movably installed at the four corners of the bottom of the base 1. The design of the universal wheels 23 allows the device to move freely, thereby increasing its convenience. A top cover 21 is movably installed on the top of the housing 16. An exhaust hole 22 is opened on the top of the top cover 21. The top cover 21 can close the operation buttons 20. The purified air will be discharged through the exhaust hole 22. The positions of the air inlet 17 and the exhaust hole 22 can be set according to the placement.
[0022] Working Principle: First, the operator can connect the pneumatic cylinder 15, control panel 18, display screen 19, and operation buttons 20 via wires, and move the base 1 and housing 16 using casters 23. Then, the pneumatic cylinder 15 is activated. The operation of the pneumatic cylinder 15 causes the support frame 12 to slide. The support frame 12 then drives the guide rod 11 to slide inside the circular tube 10. At this time, the guide rod 11 drives the slider 14 to slide inside the groove 13 until the bottom of the support frame 12 is placed on the working ground. The guide rod 11 and support frame 12 then provide auxiliary support for the housing 16. Next, when the anti-collision plate 7 receives an external impact, it will cause the moving plate 6 to slide. The moving plate 6 will then drive the moving block 4 to slide inside the strip groove 2 and on the surface of the circular rod 3. Subsequently, the moving block 4 will compress the buffer spring 5. At this time, the anti-collision plate 7 will cause the damping rod 8 to retract, and the anti-collision plate 7 will compress the return spring 9, thus creating a damping buffer effect.
[0023] The impact force can be buffered by the buffer spring 5 and the return spring 9.
[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
