[0049] Please see Figure 1-5 The present invention provides a technical solution: a clean bench, comprising a bench body 1, wherein a shell 7 is fixedly assembled on the upper end of the bench body 1, and the front wall of the shell 7 is designed to be open.
[0050] A door cover 2 is fixedly connected to the front wall of the outer shell 7 and the main body of the workbench 1. Its lower end abuts against the ground. The door cover 2 is connected to the opening of the front wall of the outer shell 7.
[0051] An air pre-purification device 3 has an air input component 4 fixedly connected to one side of it, and a bellows pipe with a valve fixedly connected to the other side of the air pre-purification device 3.
[0052] One end of the bellows with valve 5, away from the air pre-purification device 3, is fixedly connected to the side wall of the outer casing 7.
[0053] The air pre-purification device 3 is fixedly equipped with a shock-absorbing base 6 at its lower end, with its lower end resting against the ground.
[0054] Specifically, in this embodiment, the air pre-purification device 3 is used to pre-purify the air entering the housing 7 to ensure the cleanliness of the air entering the housing 7; the valve-equipped bellows 5 is a rubber bellows with a valve installed. When the valve is closed, the air exchange can be stopped. The air input component 4 output end is connected to the housing 7 through the valve-equipped bellows 5. When the air pre-purification device 3 vibrates during operation, the rubber bellows deforms with the vibration, greatly reducing the amount of vibration transmitted to the workbench body 1.
[0055] The air pre-purification device 3 is installed on the upper part of the shock-absorbing base 6, which is installed on the ground. The shock-absorbing base 6 provides shock absorption support for the air pre-purification device 3, reducing noise generation.
[0056] Furthermore, the separate placement of the air pre-purification device 3 is reflected in the fact that its outer shell is not directly connected to the outer shell 7 or the outer wall of the workbench body 1, and the three are not attached to each other. The air pre-purification device 3 is connected to the outer shell 7 through a bellows pipe with a valve 5.
[0057] More specifically, the outer shell 7 covers the upper part of the workbench body 1, and the front opening of the outer shell facilitates experimental operations on the upper surface of the workbench body 1. A door cover 2 is installed on the outer shell 7 and the front wall of the workbench body 1 for shielding, and the operator stands inside the door cover 2.
[0058] It is understandable that the door cover 2 or the outer shell 7 is equipped with an exhaust structure for ventilation.
[0059] In some embodiments, the door cover 2 includes:
[0060] The shield 21 has an opening at the rear end, and the rear end of the shield 21 is fixedly connected to the outer shell 7 and the front wall of the workbench body 1.
[0061] The front wall of the shield 21 has an entrance / exit window 22, and its edge is hinged to a door 23;
[0062] The door 23 is fastened inside the entrance / exit window 22;
[0063] The outer wall of the shield 21 has an exhaust port 24.
[0064] Specifically in this embodiment, the door 23 of the front wall of the shield 21 is opened outward to allow entry and exit through the window 22. When the device is in use, the operator enters the shield 21 and then closes the door 23. The rear wall of the shield 21 is fixedly connected to the outer shell 7 and the front wall of the workbench body 1 by bolts, which facilitates disassembly and maintenance when needed.
[0065] Furthermore, in this embodiment, the bottom surface of the shield 21 is sealed and directly rests against the ground; in other embodiments, it can be sealed.
[0066] More specifically, the outer wall of the shield 21 is provided with an exhaust port 24 for expelling the air that enters the outer casing 7 and for ventilation;
[0067] It is understandable that a dust filter is installed inside the exhaust port 24 to prevent dust and impurities from entering the door cover 2 and the outer casing 7.
[0068] In some embodiments, first ultraviolet lamps 71 are uniformly fixedly mounted on the left and right sides of the inner wall of the outer casing 7. After the first ultraviolet lamps 71 are connected to an external power source and powered on, they work to sterilize the operating space inside the outer casing 7 in real time, ensuring a clean operating environment.
[0069] In some embodiments, the air pre-purification device 3 includes:
[0070] The box 31 has a second ultraviolet lamp 32 uniformly fixedly mounted on its inner wall top surface;
[0071] The two ends of the bellows 5 with valves are fixedly connected to the outer walls of the housing 31 and the outer shell 7, respectively.
[0072] The enclosure 31 has an opening on the side away from the outer shell 7, and the opening end of the enclosure 31 is fixedly connected to a conical cover 33;
[0073] The output end of the air input component 4 is fixedly connected to the middle part of the outer wall of the conical cover 33 on the side away from the box 31;
[0074] A filter plate 34 is longitudinally fixed inside the conical cover 33.
[0075] Specifically in this embodiment, the air input component 4 is used to introduce outside air into the conical hood 33, which is filtered by the filter plate 34 inside the conical hood 33 and then enters the box 31. The second ultraviolet lamp 32 inside the box 31 is powered on to sterilize the air.
[0076] Furthermore, multiple second ultraviolet lamps 32 are provided and located on the top surface of the inner cavity of the box 31, so that ultraviolet light can be evenly irradiated into the inner cavity of the box 31.
[0077] More specifically, the opening end of the conical cover 33 is fixedly connected to the edge of the opening end of the box 31 by bolts, and the filter plate 34 can be easily cleaned and maintained after the bolts are removed;
[0078] It is understandable that the output end of the air input component 4 is fixedly connected to the middle of the smaller end of the conical cover 33, and the air intake diffuses as the inner diameter of the conical cover 33 increases.
[0079] In some embodiments, there are two filter plates 34, which are longitudinally fixedly assembled in the inner cavity of the conical cover 33 on the side near the box 31.
[0080] Specifically, in this embodiment, two filter plates 34 are provided along the air intake direction to perform multi-stage purification of the incoming air and ensure the purification effect.
[0081] Furthermore, the pore sizes of the two filter plates 34 can be the same or different. When they are different, the pore size of the filter plate 34 on the side away from the air input component 4 is smaller, thereby improving the effect of multi-stage filtration.
[0082] In some embodiments, a uniform air distribution net 35 is longitudinally fixedly mounted on the side of the conical cover 33 away from the box 31, and the uniform air distribution net 35 is located between the filter plate 34 and the air input component 4. The supplied air is uniformly dispersed by the uniform air distribution net 35 and then filtered and purified by the filter plate 34.
[0083] In some embodiments, the air input component 4 includes:
[0084] Air pump 42 is fixedly mounted on the outer wall of conical cover 33, and the output end of air pump 42 is fixedly connected to the middle part of the outer wall of conical cover 33 away from box 31.
[0085] The input end of the air pump 42 is fixedly connected to the air inlet pipe 41 with a valve.
[0086] Specifically, in this embodiment, the driving component is an air pump 42, which supplies external air into the housing 31. In other embodiments, a fan may also be used.
[0087] Furthermore, the input end of the air pump 42 is connected to the valved air inlet pipe 41, which is an air inlet pipe equipped with a valve. When the device is not in use, the valve on the air inlet pipe is closed.
[0088] In some embodiments, the shock-absorbing base 6 includes:
[0089] Flat plate 61, with support columns 62 vertically fixed at the four corners of its bottom surface;
[0090] The lower ends of the four pillars 62 are fixedly equipped with shock-absorbing support seats 63 to provide shock absorption support for the air pre-purification device 3.
[0091] In some embodiments, the shock-absorbing support 63 includes:
[0092] A top plate 631 and a bottom plate 632 are arranged in parallel vertically.
[0093] Shock absorbers 633 are uniformly and longitudinally fixedly assembled on the opposite surfaces of the top plate 631 and the bottom plate 632.
[0094] The outer wall of the shock absorber 633 is fitted with a shock-absorbing spring 634, and its two ends abut against the opposite surfaces of the top plate 631 and the bottom plate 632 respectively. The shock absorber 633 works together with the shock-absorbing spring 634 to achieve the shock absorption effect. Multiple sets of evenly distributed shock absorbers 633 and shock-absorbing springs 634 ensure uniform and effective shock absorption.
[0095] In some embodiments, a guide rod 64 is fixedly mounted on the upper surface of the base plate 632, and the guide rod 64 and the shock absorber 633 are distributed alternately.
[0096] The upper end of the guide rod 64 extends longitudinally through the top plate 631, guiding the damping direction of the damping support 63 longitudinally and preventing the damper 633 from being affected by the deflection force.
[0097] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
