Description
Technical Field
The invention relates to humidifier technology, in particular to an ultrasonic humidifier.
Background
The traditional ultrasonic humidifier comprises a base and a water tank, wherein the water tank is connected above the base, and the water quantity flowing into the base is controlled through the bottom structure of the water tank, so that water mist is generated when the water level covered on the energy converter has a fixed height. Accordingly, the conventional ultrasonic humidifier has at least two drawbacks: firstly, the water tank needs to be detached from the base to be added with water, so that the water tank is inconvenient to use; secondly, the atomization effect depends on good cooperation with the bottom structure of the water tank, and the atomization effect needs to be improved.
Accordingly, the structure of the humidifier is being studied and improved, so that the atomization ability is improved, and an optimal humidification effect is desired. CN2013105638692 proposes an upper water-adding ultrasonic humidifier: an energy collecting ring assembly is arranged above the ultrasonic oscillation head, and the upper end of the energy collecting ring assembly is fixedly connected with an energy collecting ring floater; the energy collecting ring component comprises at least two sleeves which are vertically and slidably nested with each other, and the length and the diameter of the sleeves are gradually reduced from bottom to top, and the energy collecting ring component is transversely limited and vertically moves up and down along with the energy collecting ring floats according to the change of the water level; the energy-gathering ring assembly further comprises a hanging plate fixedly connected with the upper end of the uppermost sleeve, the hanging plate is fixedly connected with the energy-gathering ring floater, and the hanging plate is circular and vertically matched with the energy-gathering ring guide rail in a sliding mode. However, this solution has the following drawbacks:
1. when the water level in the water tank is higher, the sleeve pipes of the energy gathering ring assembly are lengthened after being sleeved, so that the axial length of the energy gathering ring assembly is longer, the lower tail end of the energy gathering ring assembly is not provided with a limiting or guiding element, ultrasonic energy generated when the ultrasonic oscillation head works can vibrate water, the lower tail end part of the energy gathering ring assembly can float and swing, the axial aperture of the energy gathering ring assembly cannot be ensured to be just above the ultrasonic oscillation head, that is, the energy generated by the ultrasonic oscillation head cannot be effectively guided to the water surface by the energy gathering ring assembly, and thus the energy gathering effect cannot be achieved.
2. By varying the length of the energy gathering ring assembly with the water level, one of the objectives is to maximize the consumption of water in the tank by atomization! However, even if the sleeves of the energy collecting ring assembly are completely overlapped, the lowermost sleeve with the largest pipe diameter has a certain axial height, corresponding to the energy collecting ring assembly, and if the water level in the water tank is lower than the minimum axial height of the energy collecting ring assembly, the ultrasonic energy is gathered to the water level, but the water level is lower than the upper port of the energy collecting ring assembly, so that the ultrasonic energy is difficult to vibrate water into water mist in the sleeve with the smaller pipe diameter, the atomization amount is small, and the humidifying effect is poor. That is, when the water level of the water tank is lower than the minimum axial height of the energy-collecting ring assembly, the energy-collecting ring is ineffective, but more water still exists in the water tank and cannot be atomized effectively, so that the humidifier cannot have a due humidifying effect.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides the ultrasonic humidifier which is simple in structure and reliable in operation, so that the humidifier can maintain an optimal atomization working state, and the humidifying capacity is improved.
The invention is realized by adopting the following technical scheme: an ultrasonic humidifier comprises a base, a water tank connected with the base, a cover body covered on the water tank and a blowing device arranged in the water tank; the bottom surface of the water tank is provided with a lower concave part, and the bottom of the lower concave part is provided with a transducer; the energy collector floats on the water surface of the water tank and the axial center of the energy collector is provided with an energy collecting shaft hole, and the central axis of the energy collecting shaft hole is consistent with the central axis of the energy converter.
The vertical height between the upper surface of the energy converter and the bottom surface of the water tank is not smaller than the axial height of the energy collector, the axial height of the energy collector does not exceed the preset minimum working water level height, and the preset minimum working water level height refers to the distance between the water surface of the water tank and the upper surface of the energy converter when a water shortage prompt is sent.
Wherein, the aperture of the energy-gathering shaft hole gradually becomes smaller from bottom to top.
The energy collector comprises a collector body, an upper buoyancy part and a lower buoyancy part which are respectively arranged at the upper tail end and the lower tail end of the collector body, and an energy collecting shaft hole is formed in the collector body.
The air blowing device comprises an air duct, a fan and an air inlet which are arranged below the air duct, and an air outlet which is arranged above the air duct.

The cover body comprises a water tank cover and a fog nozzle cover which are mutually independent, the fog nozzle cover is arranged at the upper tail end of the isolator, and a fog nozzle is arranged on the fog nozzle cover.
Compared with the prior art, the invention has the following beneficial effects:
1. the invention has simple structure and lower realization cost, the energy converter is arranged in the concave part by arranging the concave part at the bottom of the water tank, and when the humidifier gives out a water shortage prompt, a small amount of residual water is almost only left in the concave part, thereby ensuring that the humidifier can almost use all water in the water tank for atomization in a normal working state.
2. According to the invention, the energy concentrator guided by the limiting cylinder is utilized to concentrate and guide ultrasonic energy generated by the energy transducer to the water surface, so that the atomization capacity is improved; and the axial height of the energy collector is not more than the preset minimum working water level, so that the energy collector can always play a role in energy collection and guide when the residual water level in the water tank is lower but not lower than the preset minimum working water level, and the humidifier is ensured to maintain stable atomization amount, thereby improving the working stability and reliability of the humidifier.
3. According to the invention, the isolator is arranged in the water tank, and the pressurizing cavity of the humidifier is reduced by using the isolator, so that the pressure of water mist is larger, the sprayed distance is longer, and the humidifying capacity of the humidifier is further improved.

Description of the embodiments
Referring to fig. 1 to 4, an ultrasonic humidifier according to the present invention includes: a base 11, a water tank 12 arranged on the base 11, a cover 13 arranged on the top of the water tank 12, and a fog outlet nozzle 14 arranged on the cover 13; a blower device arranged in the water tank 12, the blower device comprises an air duct 21, a fan 22 and an air inlet 23 arranged below the air duct 21, and an air outlet 24 arranged above the air duct 21; the bottom of the water tank 12 is provided with a lower concave part, and the bottom of the lower concave part is provided with a transducer 16; the limiting cylinder 3 is fixed on the concave part, the limiting cylinder 3 is positioned above the transducer 16, and the central axis of the limiting cylinder 3 is consistent with the axial central axis of the transducer 16; the limiting cylinder 3 is provided with a plurality of through holes 31, the inside of the limiting cylinder 3 is provided with an energy collector 4, the energy collector 4 comprises a collector body 41 with an energy collecting shaft hole 411 in the axial center, the outer side surface of the collector body 41 is provided with a plurality of reinforcing ribs 412, the upper tail end and the lower tail end of the collector body 41 are respectively provided with an upper buoyancy part 42 and a lower buoyancy part 43 which are circular, and the energy collector 4 floats on the water surface of the water tank 12 and moves up and down axially along with the change of the height of the water surface in the limiting cylinder 3.
The cross section of the concave part is any shape such as square, round, trapezoid and the like. Preferably circular, i.e. the recess is a cylindrical recess.
The upper buoyancy part 42 and the lower buoyancy part 43 can provide buoyancy to enable the energy collector 4 to float on the water surface of the water tank 12, so that the upper buoyancy part 42 is consistent with the water surface of the water tank 12, and the upper buoyancy part 42 and the lower buoyancy part 43 are in clearance fit with the inner wall of the limiting cylinder 3, so that the central axis of the energy collecting shaft hole 411 is ensured to be coincident with the central axis of the limiting cylinder 3 and consistent with the axial central line of the transducer 16.
Ultrasonic energy generated by the transducer 16 enters the energy collecting shaft hole 411 upwards, and the ultrasonic energy is collected and guided to the water surface by the energy collecting shaft hole 411, so that water mist is generated by vibration. The fan 22 works to suck air into the air inlet 23 through the air duct 21 and blow the air out from the air outlet 24, so that the pressure above the water tank 12 is increased, and air flow is generated to blow out water mist from the mist outlet nozzle 14. Also, when the aperture of the energy collecting shaft hole 411 becomes smaller from bottom to top, the humidifier can obtain a better mist outlet effect through the energy collector 4.
In order to avoid the situation that the water level in the water tank 12 is too low and the working failure occurs, the invention sets the transducer 16 and the lower end of the limiting cylinder 3 at the bottom of the concave part, and the vertical height between the upper surface of the transducer 16 and the bottom surface of the water tank 12 (i.e. the concave height or concave distance of the concave part) is not less than the axial height of the energy collector 4 (i.e. the axial length of the energy collecting shaft hole 411), and the axial height of the energy collector 4 is not more than the preset minimum working water level of the ultrasonic humidifier (wherein, a water level detection device is arranged in the water tank 12, and when the height between the water surface in the water tank 12 and the surface of the transducer 16 is detected to be less than the preset minimum working water level, a water shortage prompt signal is sent out and the humidifier can be stopped, which is the prior art and is not described in detail herein). Thus, when the ultrasonic humidifier stops operating due to a lack of water, only a small portion of water remains in the recess, so that the water in the water tank 12 can be maximally exhausted. For example, the concave portion is provided as a circular groove slightly larger than the limiting cylinder 3, so that the height of the circular groove=the preset minimum working water level height=the axial height of the energy collector 4, and when the ultrasonic humidifier stops working due to water shortage, almost all the water in the water tank 12 is used up.
Therefore, compared with the Chinese patent application CN2013105638692 mentioned in the background art, the technical scheme of the invention is a new way, and the water in the water tank 12 can be almost consumed in a normal working state, so that one of the purposes of the invention is realized; furthermore, the present invention does not require the energy concentrator 4 to be provided in a variable axial height structure similar to CN2013105638692, so that the structure of the energy concentrator 4 can be simplified and the dependence on the energy concentrator 4 can be reduced.
Another object of the present invention is to achieve upper water addition without the need to remove the water tank 12. When the water in the water tank 12 is consumed, the cover 13 is opened to add water into the water tank, so that the operation is simple and the use is convenient for users.
In addition, an overflow port 15 is provided above the water tank 12, and the position of the overflow port 15 is lower than the position of the air outlet 24. The overflow port 15 is used for overflowing the water tank 12 when the water is full, so that the water is prevented from flowing back into the air duct 21 from the air outlet 24 to damage the humidifier.
In addition, a baffle 131 extending downward is provided at the edge of the cover 13 to block the overflow port 15. When the cover 13 is lifted to add water, the overflow port 15 is opened; when the cover 13 is assembled on the water tank 12, the baffle 131 resists the overflow opening 15, so that water and mist in the water tank 12 cannot overflow from the overflow opening 15.
In connection with another embodiment shown in fig. 5. Compared with the embodiment shown in fig. 2, in this embodiment, the separator 17 is added in the water tank 12, the air duct 21 and the limiting cylinder 3 are arranged in the separator 17, the upper end of the separator 17 is connected with the cover 13, the lower end of the separator 17 is fixed on the bottom surface of the water tank 12, and the lower end of the separator 17 is provided with the water flow port 171, so that water outside the separator 17 can enter the separator 17 to increase the water surface equal height inside and outside the separator 17, and the part inside the separator 17 and above the water level of the water tank forms the pressurizing cavity of the humidifier. Therefore, the space above the water level of the water tank 12 is isolated as a pressurizing chamber by the isolator 17, i.e., the space size of the original pressurizing chamber is reduced. Under the equivalent condition, the pressurizing cavity with smaller space can obtain larger pressure more easily, so that the water mist can be sprayed out from the mist outlet nozzle 14 more far, and the humidifying capacity of the humidifier can be improved.
Based on this, since the above-water surface portion of the water tank 12 is divided into two independent portions by the separator 17, the cover 13 is also divided into the water tank cover 131 and the fog nozzle cover 132 independent of each other for further convenience of use by the user; the fog nozzle cover 132 is arranged at the upper end of the isolator 17, and the fog nozzle cover 132 is provided with a fog nozzle 14; the remainder of the cover 13 except the demister nozzle cover 132 is the water tank cover 131. Thus, the water tank cover 131 is opened to add water into the water tank 12, and the normal operation of the humidifier is not affected during the water adding operation.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
