Detailed Description

The present invention will be described below based on examples, but the present invention is not limited to only these examples. In the following detailed description of the present invention, certain specific details are set forth. It will be apparent to one skilled in the art that the present invention may be practiced without these specific details. Well-known methods, procedures, and components have not been described in detail so as not to obscure the present invention.

Further, those of ordinary skill in the art will appreciate that the drawings provided herein are for illustrative purposes and are not necessarily drawn to scale.

Unless the context clearly requires otherwise, throughout the description and the claims, the words "comprise", "comprising", and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is, what is meant is "including, but not limited to".

In the description of the present invention, it is to be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified.

The water storage groove 11, the liquid level switch groove 12 and the humidification region groove 13 are spaced from each other to reduce the amount of water stored in the water tank 1, thereby preventing water from overflowing from the water tank 1 and reducing the evaporation amount. However, when the humidifier shakes, water cannot rapidly circulate between the grooves, and thus the level switch in the level switch groove 12 cannot accurately reflect the water level of the water tank 1, which results in erroneous switching of the level switch.

In order to solve the problems, in the invention, the liquid level switch groove 12 is respectively communicated with the water storage groove 11 and the humidification region groove 13 through the first passage and the second passage, so that when the liquid level switch groove 12 inclines or shakes, the liquid in the liquid level switch groove 12 can be rapidly communicated with the water storage groove 11 and the humidification region groove 13 through the passages, the liquid level in the liquid level switch groove 12 can be rapidly stabilized, the sensitivity of the liquid level switch for adjusting the liquid level is improved, and the use reliability of a humidification device adopting the liquid level switch groove is further improved.

Further, the water storage groove 11 is communicated with the humidification region groove 13 through a third passage, so that water in the water storage groove 11 can enter the humidification region groove 13 through the third passage, and water supply to the humidification region is realized.

Further, liquid level switch recess 12 is close to water storage recess 11 and sets up for liquid level switch can in time make the response to the water level, improves the accuracy that liquid level switch detected, avoids the water in the basin 1 to exceed the working water level.

The arrangement of the first, second, and third passages is not limited, and communication among the grooves may be achieved, and in a specific embodiment, as shown in fig. 1 and 2, the first passage is a first communicating groove 14 formed by a sink bottom surface 17 being concave, the second passage is a second communicating groove 15 formed by a sink bottom surface 17 being concave, and the third passage is a third communicating groove 16 formed by a sink bottom surface 17 being concave. In order to ensure that the liquid between the grooves can completely circulate, the phenomenon that the liquid is stored in one of the grooves for too long is avoided, and the bottom surfaces of the communicating grooves and the grooves are flush with each other.

Further, the water storage groove 11 of the water tank 1 has a stepped groove structure including a first groove unit 111 and a second groove unit 112 located at a lower portion of the first groove unit 111, a radial dimension of the first groove unit 111 is larger than a radial dimension of the second groove unit 112, and the first groove unit 111 and the second groove unit 112 are preferably circular grooves and are coaxially arranged. The water storage groove 11 is set to be in a stepped groove structure, so that water is only stored in the second groove unit 112 at the lower part (detailed description is given later), namely the working water level of the humidifying device is set at the position of the step surface 113 of the stepped groove structure or lower than the position of the step surface 113, the water storage amount is reduced, the evaporation area is small, the evaporation amount of the water in the water tank 1 is reduced, the water vapor is unlikely to flow to the inner wall of the humidifying device body shell to be condensed, the water leakage false phenomenon is caused, the working environment of electric devices is optimized, and the service life of the electric devices is prolonged.

The pillar structures 114 are preferably integrated with the bottom surface of the second groove unit 112.

Furthermore, the plane of the notch of the liquid level switch groove 12 and the plane of the notch of the humidification region groove 13 are both higher than the step surface 113 of the stepped groove structure, that is, the bottom surface 17 of the water tank where the liquid level switch groove 12 is located and the bottom surface 17 of the water tank where the humidification region groove 13 is located are both higher than the step surface 113 of the stepped groove structure, because the working water level of the humidification device is set at the position of the step surface 113 of the stepped groove structure or lower than the position of the step surface 113, the other areas of the bottom surface 17 of the water tank except the water storage groove 11, the liquid level switch groove 12 and the humidification region groove 13 are all higher than the working water level of the humidification device, the area of the water tank 1 lower than the working water level is small, and only in the three groove areas, therefore, the amount of water in the water tank is small, and the water occupies a very small ratio compared with the whole space formed by the side wall of the water tank, therefore, the water tank can hardly overflow when the whole machine tilts and shakes in the daily use process. Furthermore, the whole humidifying device generally falls down when the humidifying device is inclined by 11-15 degrees, and the water tank provided by the invention does not overflow water under the angle.

The height of the second groove unit 112 determines the maximum liquid level in the water reservoir, and setting the height of the second groove unit 112 to be small reduces the water storage amount in the water reservoir.

Further preferably, the peripheral shape of the drainage device 21 is adapted to the shape of the side wall of the first groove unit 111, that is, after the drainage device 21 is inserted into the first groove unit 111, the peripheral wall of the drainage device 21 is in contact with the inner side wall of the first groove unit 111, so that the installation reliability of the water supply tank 2 is improved, a certain sealing effect can be achieved on the water in the second groove unit 112, and the water is not easy to overflow when the humidifying device shakes.

Furthermore, the side wall of the water supply tank 2 is also abutted against the limit protrusion 18 on the side wall of the water tank 1, the water supply tank 2 is further limited through the limit protrusion 18, the installation reliability of the water supply tank 2 is improved, in addition, the limit protrusion 18 can also play a certain guiding role in setting, the installation of the water supply tank 2 is guided, and the installation convenience of the water supply tank 2 is improved.
