Background

In the existing ultrasonic humidifier, a main machine part of the existing ultrasonic humidifier is mostly arranged at the bottom of a box body, water is controlled to enter a water tank in a mode of flowing to a low position by utilizing water, and then reasonable water depth is controlled, and then water is oscillated by an oscillating piece to form mist to be blown out. Among them, the conventional ultrasonic humidifier is classified into an intermittent water supply mode and a direct water supply mode according to a water supply mode.

The intermittent water supply scheme includes two modes of adding water at the lower part and adding water at the upper part. The lower water adding scheme realizes intermittent water supply to the water tank by inverting the tank body and opening the floater by utilizing atmospheric pressure. However, the box body is extremely high in sealing requirement and cannot be cleaned, and meanwhile, the box body is separated from the main machine, so that the problems of easiness in pouring, water leakage and the like exist, and water adding is extremely inconvenient. The upper water adding scheme is that the opening and closing of the water outlet are controlled through buoyancy and a spring, or the opening and closing of the box body are realized through an electromagnetic valve, and water is discharged to the water tank for humidification. However, the seal of the water outlet is easy to lose efficacy and overflow is easy to cause, the box body is separated from the top cover of the main machine and is easy to fall, and the building block type building and placing is easy to disperse.

In the direct water supply scheme, a box body and a main machine are generally integrated, the oscillation energy is concentrated through an energy-gathering ring, and then deeper water is beaten into mist to be blown out. However, in the scheme, the liquid level in the box body cannot be too high, so that the water in the box body can be only halved, and the whole humidifier is scattered in structure and easy to lose.

Referring now to fig. 1-5, a humidifier 100 according to an embodiment of the present invention is described.

As shown in fig. 1 to 5, a humidifier 100 according to an embodiment of the present invention includes: the device comprises a box body 10, a main machine 20, an atomizing part 30 and a liquid level control part 40.

According to the humidifier 100 of the embodiment of the present invention, the main unit 20 includes the main body portion 21 and the protruding portion 22. The main body 21 is mounted on the case 10, and the protrusion part 22 is connected to the main body 21 and protrudes into the case 10, so that the liquid in the case 10 enters the protrusion part 22 and the atomization operation is performed in the protrusion part 22.

Specifically, the protruding portion 22 defines an atomizing chamber 22a and a mist outlet channel 22b, the atomizing chamber 22a is a place for atomizing the liquid in the protruding portion 22, and the mist outlet channel 22b is used for guiding the mist in the atomizing chamber 22a to the outside. The inlet 22 is further provided with a liquid inlet 22c for supplying liquid to the atomizing chamber 22a for continuous atomization. The atomizing member 30 is provided on the protruding portion 22 for atomizing the liquid in the atomizing chamber 22a, and the liquid control member 40 is used for controlling the opening and closing of the liquid inlet 22 c. When the amount of the liquid in the atomizing chamber 22a is insufficient, the liquid control member 40 opens the liquid inlet 22c to allow the liquid in the tank 10 to flow to the atomizing chamber 22 a; when the amount of liquid in the atomizing chamber 22a is sufficient, the liquid control member 40 closes the liquid inlet 22c to prevent the liquid level in the atomizing chamber 22a from being too high to affect the atomizing effect of the atomizing member 30.

In the existing humidifier, an atomization chamber or a water tank is arranged on a host machine, liquid inlet is controlled by utilizing the principle that water flows to a low position, so that liquid in a box body can be used for humidification, and the box body is usually arranged above the host machine. If the main machine and the box body are of a split structure, the humidifier can be wholly tilted and scattered once the gravity center of the box body is unstable due to the fact that the gravity center of the box body is located above the main machine, and the box body is difficult to seal. If the main machine and the box body are of an integral structure, too much water cannot be added into the box body.

In the scheme of the embodiment of the invention, the extending part 22 is arranged on the main machine 20, so that the extending part 22 can extend below the liquid level of the box body 10, and the liquid level control part 40 is used for controlling the liquid inlet amount, and the brand new structure and the liquid inlet mode relieve the limitation on the structure of the humidifier, enable the positions and the structure selection of the box body 10 and the main machine 20 to be more flexible and diversified, and the liquid level height of the box body 10 is not limited by the position of the atomizing part 30 any more.

First, since the atomizing member 30 and the atomizing chamber 22a are provided on the protruding portion 22, that is, the atomizing place is not in the main body portion 21 but protrudes into the housing 10 along with the protruding portion 22, the internal space of the housing 10 is fully utilized, and water does not need to be introduced into the main body portion 21. Since the main body 21 is generally provided with a controller, a mist amount adjusting member (or a fan or a speaker), and the like, the sealing requirement for the main body 21 is greatly reduced after liquid is not introduced any more.

Secondly, because the atomizing place is not in main part 21, no longer set up basin, the atomizing chamber that is used for atomizing in main part 21, be favorable to main part 21 to change shape, thickness according to mounted position and outward appearance demand. Particularly, after the main body 21 is thinned, the main body 21 is disposed at the bottom, the top or the side of the case 10, and the main body 21 and the case 10 are detachably connected or integrally arranged (i.e., not detachable when used by a user), so that the center of the humidifier can be prevented from being too far away from the center of gravity of the case 10, and the humidifier can be prevented from being easily tilted.

Thirdly, because the atomizing part 30 and the atomizing cavity 22a are arranged on the extending part 22, the mist can be guided out only through the mist outlet channel 22b after the atomization is finished, if the extending part 22 and the box body 10 need to be sealed, the sealing connection part does not need to be drained, and the sealing difficulty is much simpler than that of the existing scheme.

In addition, because the box is installed in the upper end of host computer mostly among the current scheme, if liquid contains impurity in the box, impurity receives the action of gravity also can flow to atomizing chamber or basin along with the rivers in, finally adheres to on chamber wall or atomizing surface, is difficult to wash. In the scheme of the invention, if impurities are deposited at the bottom of the box body 10, the impurities can be prevented from being accumulated on the surface of the atomizing cavity or the atomizing part due to the action of gravity. Compared with the impurities deposited on the surface of the atomizing cavity or the atomizing part, the impurities deposited on the bottom of the box body are easier to clean.

According to the humidifier 100 of the embodiment of the invention, the extending part 22 is arranged on the main machine 20, and the atomizing member 30 and the atomizing chamber 22a for forming mist are arranged in the extending part 22 and extend into the case 10, so that water leakage between the main body part 21 and the case 10 is avoided, and the light and thin design of the main body part 21 is facilitated. Thus, with reasonable arrangement, no matter where the main unit 20 is installed on the cabinet 10, the situation that the center of gravity of the cabinet 10 is too high to cause the cabinet to be easily tilted and scattered can be avoided, and the sealing requirement of the humidifier 100 is also lowered. Since the impurities in the case 10 are not easily caused to flow toward the atomization chamber 22a by gravity after being deposited, the cleaning of the humidifier 100 is facilitated. In addition, the liquid level control member 40 controls the amount of liquid in the atomizing chamber 22a, thereby preventing the atomizing member 30 from being affected by an excessive amount of water in the housing 10.

In the embodiment of the present invention, the main body 21 of the main body 20 is located in a very various positions on the casing 10.

For example, in the schematic diagram shown in fig. 6, the main unit 20 is disposed at the bottom of the housing 10, and the top of the housing 10 is provided with a fluid infusion port 20 a. Since the protruding portion 22 is located in the case 10, the main body 21 can be disposed at the bottom of the case 10 in a flattened shape, and the center of gravity of the humidifier 100 gradually lowers when the liquid level in the case 10 lowers. In this example, the mist outlet 21a is located in the main body 21, and the mist formed in the inlet 22 is discharged from the main body 21.

For example, in the diagram shown in fig. 7, the main body 20 is provided on the side of the casing 10, the opening 10a is provided on the top of the casing 10, and the protruding portion 22 protrudes from the opening 10a into the casing 10. The mist formed in the protruding portion 22 at this time may be discharged directly from the top of the protruding portion 22, or may be discharged after passing through the main body portion 21.

For another example, the protruding portion 22 and the main body portion 21 may be connected by a hose, and the main body portion 21 may be disposed at any position of the box 10, for example, a groove is formed on a sidewall of the box 10, and the main body portion 21 is clamped in the groove.

In some embodiments of the present invention, the top or side of the tank 10 is provided with an opening 10a, or the opening 10a opens from the top of the tank 10 to the side of the tank 10, and the protrusion 22 protrudes into the tank 10 from the opening 10a, and the highest liquid level in the tank 10 is below the opening 10 a. With this arrangement, no matter which side of the case 10 the main body 21 is disposed on (even if the main body 21 is located at the bottom of the case 10), since the opening 10a is located above the highest liquid level, no sealing member is required to be disposed between the protruding portion 22 and the case 10, thereby effectively avoiding the problems of water leakage and water overflow of the humidifier.

Specifically, the main body 21 is disposed at the top or the side of the case 10, so as to avoid raising the height of the center of gravity of the case 10, and effectively avoid the problem that the humidifier is prone to toppling and falling off.

Further, the main unit 20 is detachably coupled to the cabinet 10, so that the main unit 20 is easily and conveniently mounted and dismounted to and from the cabinet 10. When the main unit 20 is detached from the housing 10, it is also convenient to store water in the housing 10 and clean the interior of the housing 10.

In the example of fig. 1, the top of the case 10 is provided with an opening 10a, the main unit 20 is fitted to the top of the case 10, the main body 21 is used to seal the opening 10a, and the protruding part 22 protrudes from the opening 10a into the case 10. The bottom of the main body 21 is provided with a ring of steps which fit the opening 10a when placed on the box 10. Thus, the main body 21 corresponds to a cover of the case 10 and can be opened and closed directly. In other embodiments, a snap connection structure or the like may be provided between the host 20 and the case 10.

Further, as shown in fig. 3 and 4, the main body 21 is provided with a mist outlet 21a, and the mist outlet passage 22b extends upward to communicate with the mist outlet 21 a. The mist outlet 21a is used for discharging mist from the main body 21, that is, guiding the mist generated in the atomizing chamber 22a out through the mist outlet passage 22b, so as to ensure the circulation of the mist. In other embodiments, the mist outlet 21a may be disposed on the box 10 or directly on the top of the protrusion 20, which is not limited herein.

Further, as shown in fig. 3 and 4, the atomizing member 30 is an oscillating member and is provided at the bottom of the protruding portion 22. Here, the oscillating piece is actuated by the main body 20 so that the oscillating piece operates to atomize the liquid. Secondly, the oscillating piece is arranged at the bottom of the extending part 22, so that mist generated by oscillation is directly upwards dissipated, the circulation stroke of the mist is short, the consumed time is short, and the mist can be rapidly gathered at the top of the atomizing cavity 22 a. In particular, the oscillating piece may be an oscillator.

In addition, the atomizing element 30 may be an electrical heating tube or an electrode rod. Since the atomization mode of the oscillator, the electric heating tube and the electrode rod belongs to the known technology, the details are not described here.

In some embodiments, the atomizer 30 may be integrated with the housing 10, so that the host 20 makes contact with the atomizer 30 through the joint with the housing 10, thereby activating the atomizer and facilitating the operation.

Further, as shown in fig. 4 and 5, the liquid inlet port 22c is located at the bottom of the protruding portion 22, and the liquid level control member 40 is a float structure fitted to the bottom of the protruding portion 22. The float structure is a pure mechanical valve body structure, and the opening and closing control of the float structure does not need to be electrified, so that the reliability of the opening and closing control in a liquid environment is improved. In addition, the liquid inlet 22c is positioned at the bottom of the extending portion 22, and the position of the liquid inlet 22c is low, so that water can be taken out as much as possible even when the liquid level of the tank 10 is low, and the float structure can control the switch by making full use of the variation relationship between the buoyancy and the gravity.

In some embodiments, as shown in fig. 5, the float structure comprises: float 41, connector 42, seal 43. The floating body 41 is positioned in the protruding part 22, the sealing member 43 is positioned outside the protruding part 22, and the connecting member 42 is connected to the floating body 41 and the sealing member 43 through the protruding part 22, respectively. The connector 42 can lift the sealing member 43 to open and seal the liquid inlet 22c by lifting the floating body 41 under the buoyancy. By adopting the built-in floater structure, the liquid level control is realized by controlling the lifting of the floater through buoyancy, the cost is low, and the manufacturing cost of the humidifier is greatly reduced. Furthermore, the float structure is arranged such that the connection member 42 passes through the protrusion 22 to connect the float 41 and the sealing member 43, so that the protrusion 22 can perform a positioning and guiding function on the float structure.

Further, the outer peripheral wall of the connecting member 42 is provided with a ring groove 421, and the sealing member 43 is clamped in the ring groove 421 to achieve fixing. In addition, the sealing member 43 includes a collar 431 and a cover 432, the collar 431 is sleeved on the connecting member 42, and the cover 432 is connected to one end of the collar 431. The connection strength of the sealing member 43 to the connecting member 42 is enhanced by the grommet 431, and the canopy 432 mainly serves as a sealing function. The umbrella cover 432 is connected at one end of the ring pipe 431 far away from the floating body 41, and the umbrella cover 432 gradually extends towards the floating body 41 in the direction from the ring pipe 431 to the periphery, so that the top of the umbrella cover 432 is closer to the liquid inlet 22c at the bottom of the stretching part 22, the liquid inlet 22c can be sealed in time through buoyancy lifting more sensitively, and the liquid in the box body 10 is prevented from excessively flowing into the stretching part 22.

In some embodiments, the float 41 may be a hollow floating ball. Under the condition of the same volume of materials, the floating ball is adopted, so that materials are saved, better buoyancy can be obtained, the floating body 41 is favorable for driving the sealing piece 43 to lift, and the liquid inlet 22c is opened and sealed.

Further, as shown in fig. 2 and 5, a fitting hole 22d is formed in the bottom wall of the protruding portion 22, the connecting member 42 fits into the fitting hole 22d, and the fitting hole 22d plays a role in supporting and guiding the connecting member 42, so that the connecting member 42 is prevented from moving up and down stably under the action of the floating body 41. The liquid inlet 22c is plural and provided around the fitting hole 22d, and here, the number of the liquid inlet 22c is not limited in the present embodiment. A plurality of liquid inlets 22c are arranged, so that the liquid circulation capacity is improved, and liquid is rapidly supplemented into the extending part 22; and set up inlet 22c around mating holes 22d for inlet 22c is whole to be arranged closely, makes things convenient for sealing member 43 fully to seal inlet 22c, improves sealed effect.

Further, the floating body 41 and the connecting piece 42 are integrated into a whole injection molding piece, so that the whole structure is firm and is not easy to break and separate. The sealing piece 43 is a flexible sealing piece, and can be tightly attached to the liquid inlet 22c during sealing, so that the sealing effect is better. Specifically, the flexible sealing sheet may be a sealant, and the like, which is not described herein.

Here, the bottom cap 222 and the working chamber 223 formed by the inlet pipe 221 can position and fix the atomizing member 30 to prevent the atomizing member 30 from being displaced. Wherein the working through hole 221a ensures that the atomizing member 30 contacts the liquid in the atomizing chamber 22a to atomize the liquid to generate the mist. In addition, the working chamber 223 limits the atomizing member 30 in a certain space region, which is beneficial to gather the heat or oscillation generated by the atomizing member 30, accelerate the atomizing speed and improve the atomizing efficiency.
