Description

Technical Field

[0001] The utility model relates to the technical field of humidifiers, in particular to a waterless shutdown device for a humidifier. Background Art

[0002] In the prior art, the waterless shutdown device and the water discharge float used in the humidifier are separated. The waterless sensing method of the humidifier is usually a reed switch combined with a floating ball with a magnet or a floating ball with a magnet combined with a Hall switch, but they do not have the function of a water discharge float. This makes the structure inside the humidifier water tank somewhat complicated. In view of the above technical problems, the utility model proposes a new waterless shutdown device for the humidifier, which can optimize the structure inside the humidifier water tank, making it simple and practical.

[0003] It can be seen that the existing technology still needs to be improved and enhanced. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the present utility model is to provide a waterless shutdown device for a humidifier, aiming to solve the technical problem in the prior art that the waterless shutdown device and the drain float of the humidifier are two independent devices, resulting in a relatively complex structure in the humidifier water tank.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A waterless shutdown device for a humidifier comprises a water tank, a support is arranged at the bottom of the water tank, a float is rotatably connected to the support, a magnet is arranged at the end of the long arm of the float; a Hall switch is arranged at the bottom of the water tank corresponding to the magnet.

[0007] Furthermore, in the waterless shutdown device for the humidifier, the magnet is arranged on the lower surface of the end of the long arm of the float.

[0008] Furthermore, in the waterless shutdown device for the humidifier, the Hall switch is arranged on the lower surface of the bottom of the water tank.

[0009] Furthermore, in the waterless shutdown device for the humidifier, the lower surface of the magnet is flush with the lower surface of the long arm of the float.

[0010] Furthermore, in the waterless shutdown device for the humidifier, a pivot is provided on the support, a through hole is provided on the float, and the pivot passes through the through hole on the float.

[0011] Beneficial effect: The utility model provides a waterless shutdown device for a humidifier. Compared with the prior art, the present application arranges a magnet and a Hall switch at the end of the long arm of the float, so that the float not only plays the role of the float of the drain valve, but also has the function of waterless shutdown, thereby eliminating the need to set up a separate waterless shutdown device and making the structure in the water tank simpler. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 This is a simplified structural diagram of the waterless shutdown device for a humidifier provided by the utility model, in which the float is in a floating state.

[0013] Figure 2 This is a simplified structural diagram of the waterless shutdown device for a humidifier provided by the utility model, in which the float is in a descending state.

[0014] Figure 3 for Figure 2 A partial enlarged view of the middle S region. DETAILED DESCRIPTION

[0015] The utility model provides a waterless shutdown device for a humidifier. To make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail below. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0016] See also Figures 1 to 3 The utility model provides a waterless shutdown device for a humidifier. The drawings are only used to explain the structural principle and are not proportional to the actual product. The drawings only depict structures related to the invention of this application, and some conventional structures are not specifically depicted.

[0017] A humidifier waterless shutdown device includes a water tank 91, a support 1 is arranged at the bottom of the water tank, a float 2 is rotatably connected to the support, and a magnet 3 is arranged at the end of the long arm of the float; a Hall switch 4 is arranged at the bottom of the water tank corresponding to the magnet. The average density of the float and the magnet as a whole is less than the density of water, that is, even if the magnet is added, the float can float normally due to the buoyancy of water.

[0018] In practical applications, the humidifier is provided with a controller (eg, a single chip microcomputer), and the Hall switch is electrically connected to the controller of the humidifier. The humidifier is provided with a controller, which is a prior art, and therefore, this application will not specifically limit or elaborate on it.

[0019] Preferably, the magnet is arranged on the lower surface of the end of the long arm of the float, which makes it easier for the magnet to be sensed by the Hall switch.

[0020] Preferably, the Hall switch is arranged on the lower surface of the bottom of the water tank. This arrangement facilitates the installation and subsequent maintenance or replacement of the Hall switch.

[0021] Preferably, the lower surface of the magnet is flush with the lower surface of the long arm of the float, that is, the magnet is embedded from the lower surface of the long arm of the float, without affecting the normal outer structure of the float.

[0022] There are many ways to realize the rotatable connection between the float and the support. Here is a preferred solution: Figure 3 As shown, a pivot 11 is provided on the support 1, and a through hole (corresponding to the pivot 11) is provided on the float, and the pivot passes through the through hole on the float.

[0023] For ease of understanding, the working principle is briefly described below: (1) Figure 1 As shown, when there is water in the water tank 92 and the water tank 91, the float floats upward in the water, and can push the drain valve 93 to open, ensuring that the water in the water tank can flow into the water tank normally; at this time, the Hall switch cannot detect the magnet, the humidifier will not shut down, and the float plays the role of the drain valve float; (2) Figure 2 As shown, when the water tank and sink are exhausted, the long arm end of the float drops under the action of gravity; the Hall switch detects the magnet, and the humidifier controller further controls the humidifier to shut down.

[0024] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and the utility model concept of the utility model, and all these changes or substitutions should fall within the protection scope of the utility model.
