[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0020] Examples, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the utility model provides a laboratory humidifying device, including a device body 1, a top cover 2 is arranged on the top of the device body 1, the device body 1 is divided into a water storage chamber 4 and a humidifying chamber 5 by a partition 3, a water supply pipe 6 is arranged in the water storage chamber 4, a float valve 7 is arranged on the water supply pipe 6, a humidifying component 8 is arranged in the humidifying chamber 5, and a water inlet pipe 9 and a spray pipe 10 are arranged at the water inlet end and the spraying end of the humidifying component 8. Among them, the humidifying component 8 can pump the water in the water storage chamber 4 into the inside through the water inlet pipe 9, and generate water mist through evaporation; the top cover 2, the device body 1, the water storage chamber 4, the humidifying chamber 5, the water supply pipe 6, the float valve 7 and the humidifying component 8 are all prior arts, and their specific structures and principles are not repeated here in this embodiment. On this basis, in order to improve the humidification performance of the device, two sets of humidification components 8 are arranged in the humidification chamber 5, and the spray pipes 10 of the two sets of humidification components 8 pass through the top cover 2 and are connected to the output valve block 11 arranged on the top cover 2. The output end of the output valve block 11 is provided with a spray pipe 12, and the output end of the spray pipe 12 is provided with a coil 13. The output end of the coil 13 is provided with a plate-type sprayer 14, and the spray end of the plate-type sprayer 14 is provided with a plurality of spray holes 141 arranged in a straight line.

[0021] Specifically, the spray ends of the two humidifying components 8 are connected by the output valve block 11, and the output valve block 11 is used to converge or divert the water mist generated by the two humidifying components 8, thereby realizing multiple working modes, such as one standby and one use and simultaneous operation, which is beneficial to improving the utilization rate of the device. The coil 13 has a universal adjustment function, which can adjust the actual direction and angle of the spray after the spray valve block outputs the spray, and the plate-type sprayer 14 can increase the coverage of the spray to improve the distribution effect of the spray moisture in the room, thereby improving the humidification performance of the device.

[0022] In order to improve the control performance of the output valve block 11 over the two humidification components 8, the utility model is provided with a spray branch 111 connected to the two spray pipes 10 inside the output valve block 11, and the distribution heights of the two spray branches 111 are different. The spray branch 111 is connected to a valve cavity 112 arranged in the vertical direction of the output valve block 11, a valve core 113 is arranged in the valve cavity 112, a valve stem 114 is arranged on the valve core, and a hand wheel 115 is arranged on the top of the valve stem 114. A spray main path 116 connected to the valve cavity 112 is arranged in the horizontal direction of the output valve block 11, and the spray main path 116 is connected to the spray pipe 12. In this way, the water mist generated by the humidification component 8 can enter the valve cavity 112 through the spray branch 111, and the valve core can be rotated by the hand wheel 115 to make the spray branch 111 communicate with the valve cavity 112 and the spray main path 116, and then finally sprayed out through the spray pipe 12, so as to achieve the purpose of confluence and improve the actual humidification performance of the device. At the same time, the scaling conditions inside the two humidifying components 8 do not affect each other, which is conducive to ensuring that the device has a long actual service life. In the case where one is needed for backup and the other is needed, the actual passage inside the actual output valve block 11 can be controlled by operating the hand wheel 115 to change the angle of the valve core.

[0023] Furthermore, the valve core provided by the utility model includes an upper core 113a and a lower core 113b, both of which are cylindrical structures. Two inlets 113c are arranged on the sides of the upper core 113a and the lower core 113b, and outlets 113d are arranged at the center of the upper core 113a and the lower core 113b, and the outlets 113d of the two are opposite. When the valve stem 114 rotates a certain angle, an inlet 113c on the upper core 113a and an inlet 113c on the lower core 113b can be in an upper and lower staggered relative position, and at this angle, the two humidification components 8 can simultaneously input spray into the spray main path 116; another inlet 113c on the upper core 113a and another inlet 113c on the lower core 113b are staggered but not opposite after the valve stem 114 rotates a certain angle, and if one of the spray branches 111 is connected to the spray main path 116, one backup and one use can be achieved.
