[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 The utility model discloses an indoor gas purification device, comprising a purifier body 1, a semi-circular installation groove is provided on the lower side of the side wall of the purifier body 1, a semi-circular air intake grille 16 is embedded in the installation groove, and air enters the purifier body 1 through the air intake grille 16.

[0025] In one embodiment, the shielding plate 2 includes a plate body 21 with a semi-circular shape, an air intake port 22 is opened in the middle of the plate body 21, and a socket 23 is opened on the air intake grille 16. The shielding plate 2 can be rotatably installed at a height position corresponding to the air intake grille 16 in the purifier body 1. When the plate body 21 rotates until the air intake port 22 coincides with the socket 23, the plate body 21 blocks the air intake grille 16. A driving device is provided on the purifier body 1, and the driving device is used to drive the shielding plate 2 to rotate in the purifier body 1 so that the shielding plate 2 blocks the air intake grille 16 or exposes the air intake grille 16. A removable air intake duct is inserted in the socket 23.

[0026] In a specific implementation, under normal conditions, the disc 21 will not block the air intake grille 16, so that the air around the purifier body 1 can evenly pass through the air intake grille 16 and be sucked into the purifier body 1 for purification when the purifier body 1 is in use. When it is necessary to absorb the gas at a specified position, the disc 21 is driven by the driving device to rotate around the axis of the purifier body 1, and stops after it rotates until the air intake port 22 and the socket 23 coincide with each other. At this time, the disc 21 blocks the air intake grille 16, and the air intake duct is connected to the interior of the purifier body 1 through the coincident air intake port 22 and the socket 23, and the other end of the air intake duct away from the purifier body 1 is aimed at the gas at the specified position. This design enables the device to more concentratedly absorb toxic gases continuously generated at welding stations in factories, such as those in factories, so that the toxic gases will not dissipate, but will be quickly absorbed and purified.

[0027] In one embodiment, the purifier body 1 includes an upper shell 12 and a lower shell 11 detachably mounted on the bottom of the upper shell 12. An air outlet is provided on the top wall of the upper shell 12. A plurality of longitudinally distributed filter discs 15 are detachably mounted inside the lower shell 11. Fan blades 14 are rotatably mounted on the inner side of the upper shell 12. A power device 13 for driving the fan blades 14 to rotate is mounted on the upper shell 12. An air intake grille 16 is embedded in the lower shell 11, and the position of the air intake grille 16 in the lower shell 11 is lower than the position of the filter disc 15 in the lower shell 11. The filter disc 15 is used to purify the air sucked into the lower shell 11. The rotation of the fan blades 14 is used to allow the air to pass through the air intake grille 16 into the lower shell 11 and the upper shell 12, and to discharge the purified air from the air outlet.

[0028] In a specific implementation, the filter disc 15 mentioned above can be a filter screen and activated carbon, etc., which is used to filter dust impurities and toxic components in the air sucked into the lower shell 11. The power device 13 is started to rotate the fan blades 14 to allow air to enter the lower shell 11. The air passes through multiple filter discs 15 from top to bottom in sequence for purification, and the purified air is discharged from the air outlet on the top wall of the upper shell 12.

[0029] In one embodiment, the driving device includes a ring gear 3 installed on the disk body 21 and a handle 5 rotatably installed on the bottom wall of the lower shell 11. The handle 5 is provided with a gear 4 meshing with the ring gear 3. The ring gear 3 is used to rotate synchronously when the gear 4 rotates, and drive the disk body 21 to rotate synchronously. The handle 5 cooperates with the lower shell 11 in a dynamic seal. A moving seat 17 is installed at the bottom of the lower shell 11. A universal wheel with a brake pad is rotatably installed at the bottom of the moving seat 17, and the gripping end of the handle 5 passes through the moving seat 17 and extends to the bottom of the moving seat 17.

[0030] In a specific implementation, the operator holds the handle 5 and rotates it, the gear 4 will rotate synchronously and drive the meshing gear ring 3 to rotate around the axis of the purifier body 1. At this time, the disk 21 rotates synchronously therewith, so that the disk 21 can rotate to a state of covering the air intake grille 16 or not covering the air intake grille 16. When the air inlet 22 of the disk 21 coincides with the socket 23 on the air intake grille 16, the disk 21 covers the air intake grille 16. The setting of the movable seat 17 can facilitate the flexible movement of the device. There is a gap between the movable seat 17 and the ground to accommodate the universal wheel. The staff can extend their hands into the gap to contact the handle 5 and adjust it.

[0031] In one embodiment, a ball rolling rod 6 is provided on the disk body 21, and the ball rolling rod 6 includes a rod body connected to the disk body 21 and a ball rotatably installed on the end of the rod body away from the disk body 21. An annular groove 7 with an annular shape is opened on the inner wall of the upper shell body 12, and the end of the ball rolling rod 6 away from the disk body 21 extends into the annular groove 7.

[0032] With this design, when the disc body 21 rotates, the ball rod 6 will synchronously perform a circular motion in the annular groove 7. At this time, the ball contacts the corresponding annular groove 7 of the upper shell 12, which can make the disc body 21 very stable and smooth during rotation adjustment.

[0033] In one embodiment, the air intake duct includes a connecting duct 8, one end of which is detachably inserted into the socket 23, and the other end of the connecting duct 8 is equipped with an air intake hopper 9, the connecting duct 8 is a hose, and the air intake hopper 9 is used to approach the toxic gas and cooperate with the purifier body 1 for concentrated absorption.

[0034] This design allows the suction hopper 9 to be very conveniently installed at the place where toxic gases are produced (such as a welding station in a factory), so that the toxic gases can be directly absorbed instead of being discharged into the air and then purified. In actual circumstances, the connecting pipe 8 can be a pipe structure with multiple branch pipe bodies, and the multiple branch pipe bodies are all equipped with suction hoppers 9, so that one purifier body 1 can quickly absorb and purify toxic gases in multiple places.

[0035] In one embodiment, a fixing device 10 is provided on the air suction hopper 9, and the fixing device 10 includes a bracket 101 installed on the air suction hopper 9, a clamp 102 hingedly provided on the bracket 101, and a fixing plate 103 installed on the clamp 102, a bolt member is provided on the clamp 102, and a lock hole is opened on the fixing plate 103.

[0036] With this design, the clamp 102 cooperates with the bolt to fix the suction hopper 9 to a circular fixing point (such as a round tube), and the fixing plate 103 cooperates with the screws inserted into the lock hole to fix the suction hopper 9 to a flat fixing point, so that the suction hopper 9 can be fixed at different installation points in cooperation with the fixing device 10 to improve the flexibility of use.
