The servo motor 61 is fixedly mounted on the side wall of the fixed plate 4, and the threaded rod 62 is fixedly mounted on the output shaft of the servo motor 61. When the servo motor 61 is started, the threaded rod 62 rotates, gradually reducing the amount of impurities entering the humidifier after humidification is completed. The threaded rod 62 is rotatably connected to the fixed plate 4 and the side wall of the housing 1. The fixed plate 4 and the housing 1 can support the threaded rod 62, the limiting rod 7 is located below the threaded rod 62, the movable seat 63 is threadedly connected to the outer surface of the threaded rod 62, and the rotation of the threaded rod 62 can push the movable seat 63 to move. The movable seat 63 is slidably connected to the outer surface of the limiting rod 7, limiting the freedom of rotation of the movable seat 63, so that the movable seat 63 can only move laterally and will not rotate. The replacement seat 64 is in an inverted T shape, and the replacement seat 64 is plugged into the outlet hole 5. The replacement seat 64 on the right can block the outlet hole 5, thereby reducing the entry of impurities into the humidifier after humidification is completed.

[0023] In addition, the connecting rod 65 is hinged between the movable seat 63 and the opposite side of the replacement seat 64. Under the connection of the connecting rod 65, the movement of the movable seat 63 can promote the lateral movement and up and down movement of the replacement seat 64, thereby realizing the blocking of the outlet hole 5 and reducing the entry of impurities into the humidifier after humidification. The guide column 66 is fixedly installed on the front wall and the rear wall of the replacement seat 64. The shape of the guide column 66 is cylindrical. The first guide groove 67 is opened on the front side wall and the rear side wall of the shell 1, and the second guide groove 68 is opened on the front side wall and the rear side wall of the shell 1 and is located on the outside of the first guide groove 67.

The guiding column 66 is movably connected to the inner walls of the first guiding groove 67 and the second guiding groove 68, and the guiding column 66 extends into the inner walls of the first guiding groove 67 and the second guiding groove 68. Under the connection of the guiding column 66, the replacement seat 64 can move horizontally and vertically along the trajectories of the L-shaped first guiding groove 67 and the second guiding groove 68, which is beneficial to retracting the replacement seat 64 provided with the humidifying port 114 into the housing 1 to be blocked, and the replacement seat 64 without the humidifying port 114 blocks the outlet hole 5, playing a role in blocking air impurities in the laboratory. The number of the movable seat 63, the replacement seat 64, the connecting rod 65, the first guiding groove 67 and the second guiding groove 68 is two each.

[0025] Please refer to Figure 2-3 As shown in the figure, a humidifying component 11 is provided on the housing 1 and the replacement seat 64. The humidifying component 11 includes an oscillator 111, a water tank 112, a hose 113 and a humidifying port 114. The oscillator 111 is installed on the inner bottom wall of the housing 1 and is the oscillator 111 of an ultrasonic humidifier. The control panel 2 is electrically connected to the servo motor 61 and the oscillator 111. After the oscillator 111 is started, it generates high-frequency mechanical vibrations. These vibrations pass through the medium of water to form a local pressure wave on the water surface, breaking the water molecules into tiny water mist. The oscillator 111 is a prior art and will not be elaborated here. The water tank 112 is installed on the top of the oscillator 111 and is used to store the water required for humidifying the laboratory. The top wall of the water tank 112 is threadedly connected with a lock cover, which is beneficial for replenishing water into the water tank 112.

[0026] Among them, the side wall of the water tank 112 is in contact with the cover plate 3. A limiting frame 12 abutted against the water tank 112 is fixedly installed on the top of the oscillator 111. The shape of the limiting frame 12 is U-shaped, which plays a role in limiting the water tank 112. The hose 113 is fixedly installed between the opposite sides of the water tank 112 and the replacement seat 64. The humidifying port 114 is opened in the replacement seat 64. The hose 113 communicates with the inner cavity of the water tank 112 and the humidifying port 114. Under the connection of the hose 113, the water mist can be introduced to the humidifying port 114 and discharged for humidification outside.

[0027] When this embodiment is in use, the servo motor 61 is started, the threaded rod 62 rotates, the movable seat 63 moves laterally, and moves in the inner walls of the guide column 66 and the L-shaped first guide groove 67 and the second guide groove 68, and the telescopic sleeve 10 guides the replacement seat 64 vertically downward, so that the left connecting rod 65 drives the left replacement seat 64 to move downward first, and then to the left, so that the humidification port 114 moves to the inside of the device shell 1 and is blocked, and the right connecting rod 65 drives the right replacement seat 64 to move left first, and then upward, and the replacement seat 64 moves to the outlet hole 5 to block the outlet hole 5, thereby preventing impurities in the laboratory from entering the humidification port 114 and sliding into the water tank 112 to cause water contamination when the humidifier is not in use.

[0028] The beneficial effects of the above embodiments are:

[0029] The humidifier for laboratory environment is provided with a replacement component 6. After the replacement component 6 is used, the movable seat 63 is moved laterally.
