BACKGROUND
Heating-type humidifiers are electrothermal humidifiers. According to the principle that electric current generates heat through electrical resistance and electrical energy is converted into heat, an electric heating pipe is submerged in water and the electric heating pipe generates heat, which causes the water to boil and turn into water vapor, thereby producing a moderate humidity environment.
An existing electrothermal humidifier generally defines a cold-water tank and a hot-water tank, the cold-water tank configured to provide the hot-water tank with water supply. The cold-water tank is arranged around the hot-water tank to achieve heating atomization while reducing the temperature of a side wall of the hot-water tank, thereby avoiding the shell of the humidifier from being affected by heat. In order to enhance the usage feeling, the electrothermal humidifier performs atomization operations in the cold-water tank and hot-water tank respectively, and combines cold and hot atomized gas to obtain the atomized gas with appropriate temperature. In the above electrothermal humidifier, the cold-water tank and hot-water tank are connected with each other, which will cause hot water backflow to the cold-water tank, leading to damage to an atomization part in the cold-water tank, such that the humidifier cannot perform the atomization operation, thereby affecting the service life of the humidifier.

The gas guide pipe 300 is arranged in the water tank and connected with the gas outlet 110, forming a gas channel. A bottom surface of the water tank 100 defines a water outlet, and a top of the water tank 100 defines the water filling port. The water filling port is configured to fill the to-be-atomized water, and the water outlet is configured to refill water to the base 200. In some embodiments, a water level indicator is arranged within the water tank 100.
Specifically, the gas guide pipe 300 is a circular pipe, which has a gas inlet end and a gas outlet end. The gas outlet end is disposed at the top of the water tank 100, so as to effectively discharge the atomized gas; the gas guide pipe 300 is arranged within the water tank 100.
As shown in FIGS. 2 to 3, the base 200 is a seat body, an upper end surface of which defines a cold gas tank 210 and a heating tank 220. The cold gas tank 210 and the heating tank 220 are relatively independent and distributed at intervals; the cold gas tank is 210 an L-shaped inner recess communicated with the gas guide pipe, and an end of a bottom surface of the cold gas tank 210 is arranged with an atomization assembly 230; the atomization assembly 230 is a device to achieve the atomization operation, such as: an atomization piece and related necessary parts, etc.; the atomization assembly 230 is arranged facing the gas guide pipe; another end of the bottom surface of the cold gas tank 210 is arranged with a water supply switch 240; the water supply switch 240 is arranged facing the water filling port and configured to control opening or closing of the water filling port, for achieving water supply to the cold gas tank 210; the other end of the bottom surface of the cold gas tank 210 defines a connection port; the water supply switch 240 may be a lever switch or floating switch, etc., for opening or closing the water outlet of the water tank 100, and controlling the opening or closing of the water outlet through a water level in the cold gas tank 210, so as to realize the water replenishment operation of the cold gas tank 210. In the embodiments, the water supply switch 240 is a lever switch as an example.
It should be noted that the cold gas tank 210 is connected to an inner cavity of the water tank 100 through the water outlet of the water tank 100, and controlled to be connected or disconnected by the water supply switch 240; the water contained in the cold gas tank 210 and the water tank 100 is at room temperature, and the not too high water temperature is intended for atomization operation.
As shown in FIG. 3, the cold gas tank 210 and the heating tank 220 are connected through a guide pipe 600.

As shown in FIG. 3, the water level of the heating tank 220 is higher than the water level of the cold gas tank 210. Specifically, the height of the bottom surface of the heating tank 220 is greater than the height of the bottom surface of the cold gas tank 210, i.e.: there is a height difference between the heating tank 220 and cold gas tank 210, and the height difference design is to prevent the inflow of hot water from the heating tank 220 into the cold gas tank 210; the height difference may be formed by the end of the guide pipe 600 connected to a heating cup 700 being higher than the other end thereof connected to the cold gas tank 210, thereby reducing the temperature of the guide pipe 600.
As shown in FIG. 3, the guide pipe 600 is a heat dissipation pipe. In some embodiments, the heat dissipation pipe is a metal pipe as a heat dissipation structure to improve heat exchange. In order to further improve the heat dissipation effect, the base 200 is arranged with a heat dissipation fan 400; an air outlet end of the heat dissipation fan 400 is arranged towards the guide pipe 600 to improve the heat dissipation effect of the guide pipe 600, thereby effectively preventing heating tank 220 from affecting the water temperature of the cold gas tank 210. It should be noted that the guide pipe 600 and the bottom surface of the cold gas tank 210 are connected, and the guide pipe 600 is disposed away from an end of the atomization piece, so as to reduce the impact of water temperature on the atomization piece.
As shown in FIGS. 2 to 3, the heating tank 220 is a water receiving tank arranged with a built-in electric heating assembly 250, and the shape of the heating tank 220 may be set according to specific practical needs. In the embodiments, the heating tank is a rectangular tank and is opened next to the cold gas tank 210. The through hole is defined on the bottom surface of the heating tank 220. Specifically, the heating tank 220 defines a ring-shaped inflow tank on the bottom surface, and a bottom surface of the ring-shaped inflow tank defines the through hole. The electric heating assembly 250 is arranged on the bottom surface of the heating tank 220.
Combined with FIGS. 4 to 6, the heating tank 220 is a heating cup, specifically: a mounting hole defined on the base, and a heating cup 700 is assembled in the mounting hole; in some embodiments, the heating cup 700 is made of stainless steel to achieve rapid heating while also preventing rust and other phenomena, thereby extending the service life of the heating cup 700; the heating cup 700 is removably arranged in the mounting hole, thereby facilitating the maintenance and replacement thereof; the heating cup 700 may be a stainless steel cup arranged with electric heating wires, for heating the water, so as to evaporate its content of water and generate hot atomized gas; the heating cup 700 is arranged near an end of the cold gas tank 210, but not communicated with the cold gas tank 210; the gas inlet end of the gas guide pipe 300 is arranged near the heating cup 700 and cold gas tank 210. It is to be noted that the heating cup 700 is near an end of the cold gas tank 210 where the atomization piece 111 is installed.
Combined with FIGS. 4 to 8, an opening of the heating cup 700 is arranged with a switch 500, and the switch 500 includes a fixing member 510 and an opening-closing member 520. The opening-closing member 520 can be displaced towards the fixing member 510 driven by a spring and is pressed to the fixing member 510 with the pressure released from the spring to reset, to seal the opening 511 defined by the fixing member 510. The opening 511 is configured to connect an inner cavity of the heating cup 700 with the gas guide pipe 300. The fixing member 510 defines a central hole at the center, and an edge of the central hole extends along its axial direction to form a tubular protrusion, an outer side of the tubular protrusion being sleeved on the spring. The opening-closing member 520 is arranged with a drive post 521 toward the fixing member 510. The drive post 521 includes a body and a limit cap; the body passes through the fixing member 510 and is connected to the limit cap, and the limit cap is screwed to a top of the body. The spring is a helical compression spring and is sleeved by the outer side of the tubular protrusion of the fixing member 510. An end of the spring abuts against a side of the fixing member 510 toward the water tank 100, and the other end of the spring abuts against a side of the limit cap of the drive post 521 toward the fixing member 510. The water tank 100 abuts against the drive post 521 and compresses the spring, to drive the opening-closing member 520 to move away from the fixing member 510 and open the opening 511 on the fixing member 510, which causes the inner cavity of the heating cup 700 and the gas guide pipe 300 to be connected; the water tank 100 is moved away from the drive post, compresses the elasticity, and releases the spring, to drive the opening-closing member 520 to be displaced close to the fixing member 510 and to press the opening-closing member 520 on the fixing member 510, thereby sealing the opening on the fixing member 510 and causing the heating cup 700 and the gas guide pipe 300 to be disconnected.
Combined with FIGS. 4 to 8, the fixing member 510 is a disc with the through hole at its center and an opening 511 defined thereon. The opening 511 is a fan-shaped hole, and a plurality of the openings 511 are arranged in the same circle at intervals; each the opening 511 is a structure that penetrates the inner cavity of the heating cup 700 and the gas guide pipe 300 to realize the export of heat gas in the heating cup 700.
Combined with FIGS. 4 to 8, the opening-closing member 520 is disposed below the fixing member 510. That is, the opening-closing member 520 is arranged closer to the inner cavity of the heating cup 700 than the fixing member 510; the drive post 521 is arranged in the middle of the opening-closing member 520, the drive post 521 protrudes from the through hole on the fixing member 510 and is matched with the water tank 100, and the opening-closing member 520 is arranged with the spring. When the water tank 100 is arranged on top of the base 200, the water tank 100 abuts against the drive post 521, the spring is in a compressed energy-storage state, and the drive post 521 drives the opening-closing member 520 to move away from fixing member 510. In this case, the opening 511 on the fixing member 510 is in an opened state, so as to conduct the inner cavity of the heating cup 700 and the gas guide pipe 300. When the water tank 100 is removed from the base 200, i.e.: when the water tank 100 is separated from the base 200, the drive post 521 is in a free state. In this case, the spring in the compressed energy-storage state performs reset energy release, driving the opening-closing member 520 to move towards the fixing member 510, and pressing the opening-closing member 520 to abut against the fixing member 510. In this way, any opening on the fixing member 510 is sealed by the opening-closing member 520 to cut off the connection between the inner cavity of the heating cup 700 and the gas guide pipe 300, thereby closing the heating cup 700, which effectively prevents the hot water in the heating cup 700 from spilling or overflowing or pouring out, so as to avoid users or other people from being scalded by the hot water in the heating cup 700.
It is to be noted that, in combination with FIGS. 4 to 8, the opening-closing member 520 may define the through hole or not, and the opening-closing member 520 may seal either opening without defining the through hole. When the through hole is defined on the opening-closing member 520, the through hole is required to be arranged in a staggered position with the opening. That is, a solid part of the opening-closing member 520 (i.e., a part of the opening-closing member without any through hole defined thereon) is required to effectively seal either opening on the fixing member 510 to achieve the switching purpose.
In the embodiments, as shown in FIGS. 4, 7 and 8, the opening-closing member 520 includes a main body and a conductor, the main body being on a disc, and the conductor being integrally connected to the main body. The conductor is adapted to the inner cavity of the heating cup 700 and affixed to the inner wall of the heating cup 700. A plurality of the through holes are defined on the main body and staggeredly distributed with a plurality of the openings 511 on the fixing member 510.
As shown in FIG. 4 and FIG. 5, to achieve efficient export of hot gas, a gas guide cover (not shown in the drawings) may be further arranged above the heating cup 700. The gas guide cover defines a gas guide port, which is communicated with the gas inlet end of the gas guide pipe 300. It should also be noted that the gas guide cover is fixed with the bottom surface of the water tank 100. Specifically, the gas guide cover is a circular cover which can be fastened to the fixing member 510, and a side of the gas guide cover facing the gas guide pipe 300 defines the gas guide port. The gas guide cover is communicated with the gas inlet end of the gas guide pipe 300 through the gas guide port. A side of the gas guide cover facing the drive post 521 is arranged with a pressure protrusion, which presses the drive post 521 towards the inner cavity of the heating cup 700.
It is to be noted that, as shown in FIGS. 4 to 8, the self-weight of the water tank 100 (i.e.: the tank not filled with water) can turn on the switch 500 at the opening of the heating cup 700. Specifically, the water tank 100 not filled with water is placed on top of the base 200 and the switch 500 at the opening of the heating cup 700 (as shown in FIG. 8, A) is turned on to open the inner cavity of the heating cup 700. That is, the inner cavity of the heating cup 700 is communicated with the gas guide pipe 300 to achieve the export of hot gas. Conversely, when the tank 100 not filled with water is removed from the base, the switch 500 at the opening of the heating cup 700 is turned off (as shown in FIG. 8, B) to close the inner cavity of the heating cup 700. That is, the inner cavity of the heating cup 700 in a connected state is disconnected with the gas guide pipe 300, to achieve hot gas off.
The above mentioned is only specific implementations of the present disclosure, but the scope of the present disclosure is not limited to it, and any variation or replacement that can be readily thought of by any person skilled in the art within the technical scope disclosed by the present disclosure should be covered by the scope of the present disclosure. Therefore, the scope of the present disclosure should be subject to the scope of the claims.
