Water-leakage-proof upward water adding humidifier

Abstract

The invention discloses a water-leakage-proof upward water adding humidifier. Opening and closing of a water outlet of a water tank are controlled by using double valve bodies by the water-leakage-proof upward water adding humidifier, so that the possibility of water leakage of the water tank is reduced, and the space occupied by the double valve bodies is reduced; and the upward water adding humidifier comprises the water tank, a water discharging part used for communicating with an atomization cavity is arranged on the water tank, a first water outlet hole and a second water outlet hole which are connected in series are formed in the water discharging part, a first valve body is arranged at the first water outlet hole, a second valve body is arranged at the second water outlet hole, thecritical point lies in the fact that a through hole is formed in an valve element of the second valve body, an valve element of the first valve body penetrates through the through hole, a detecting and driving mechanism is further arranged on the upward water adding humidifier, the detecting and driving mechanism controls the first valve body and the second valve body to act in a mode that the valve element of the first valve body and the valve element of the second valve body are driven to move, the first valve element is arranged with an auxiliary sealing ring in a sleeve mode, and when thefirst valve body and the second valve body are both closed, the auxiliary sealing ring abuts against the end face of the valve element of the second valve body.

Description

technical field [0001] The invention belongs to the technical field of humidifiers, and in particular relates to an upward water-filling humidifier. Background technique [0002] The upper water humidifier has the advantage of adding water conveniently, and is very popular among consumers. In the top-filling humidifier, the bottom of the water tank communicates with the atomization chamber through the water outlet, and a valve and a water replenishment control mechanism for controlling the action of the valve are arranged at the water outlet. When the water level of the atomization chamber drops to a predetermined height, the water supply control mechanism will open the valve at the water outlet, and the water in the water tank will flow into the atomization chamber. The valve at the position is closed to prevent the water in the water tank from continuing to flow into the atomization chamber and causing the water level in the atomization chamber to be too high.

Problems solved by technology

The above three related mechanisms will cause the water part to occupy a large vertical height (at least greater than the sum of the lengths of the two valve cores). When opening the two valve bodies, only two valve bodies can be opened one after another. The larger the moving distance, the larger the moving distance of the driving mechanism, which expands the required space, which is not conducive to the miniaturization of the humidifier; moreover, the increase of the moving distance of the lower valve body will increase the corresponding The moving distance of the reset member, for example, will make the length of the return spring longer, which will increase the driving force requirements of the driving mechanism, and reduce the driving force of the driving mechanism, and it will be necessary to reduce the reset force of the reset member, which in turn It will make it difficult for the reset part to press the water sealing part tightly on the outlet hole, resulting in poor sealing of the valve body

4. Use the wedge structure set on the two valve cores to make the two valve cores move in association, but the wedge structure is more complicated, the installation is difficult, and the production cost is increased
