Description

Ultrasonic washing device and charging base

Technical Field

The disclosure relates to the technical field of portable cleaning machines, in particular to an ultrasonic washing device and a charging base.

Background

The principle of ultrasonic cleaning is that a high-frequency oscillation signal is emitted from an ultrasonic generator, converted into high-frequency mechanical oscillation by a transducer and propagated into a medium (such as a cleaning solvent), ultrasonic waves are radiated forward at intervals in a cleaning liquid, the liquid flows to generate tens of thousands of micro-bubbles with the diameter of 50-500 μm, and the micro-bubbles existing in the liquid vibrate under the action of an acoustic field. These bubbles are formed and grown in a negative pressure region where the ultrasonic wave propagates in the longitudinal direction, and in a positive pressure region, when the sound pressure reaches a certain value, the bubbles rapidly increase and then suddenly close. When the bubbles are closed, shock waves are generated, thousands of atmospheric pressures are generated around the bubbles, insoluble dirt is damaged, and the insoluble dirt is dispersed in the cleaning liquid, and when the group particles are wrapped by the oil dirt and adhered to the surface of a cleaning piece, the oil is emulsified, solid particles are separated, so that the aim of cleaning the cleaning piece is fulfilled. In this process, known as the "cavitation" effect, the closing of the bubbles can create high temperatures of several hundred degrees and transient high pressures in excess of 1000 atmospheres.

The existing ultrasonic wave washing machine or the washing machine with ultrasonic waves has the disadvantages of complex structure, high price, large volume and inconvenient use. In addition, in the ultrasonic cleaning process, as turbidity of solid dirt, oily dirt, water-soluble dirt, and the like in water increases, an internal friction coefficient (viscosity coefficient) of water increases, which reduces a cavitation effect of ultrasonic waves, thereby reducing a cleaning effect of the ultrasonic waves. Therefore, the washing device needs to detect the situation and further, the water change can be reminded, but some washing devices in the prior art do not solve the problems.

Detailed Description

The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.

It should be noted that, if directional indication is referred to in the embodiments of the present disclosure, the directional indication is only used to explain a relative positional relationship, a motion situation, and the like between components in a certain posture, and if the certain posture is changed, the directional indication is changed accordingly.

Referring to fig. 1, an embodiment of the present disclosure provides an ultrasonic washing device 100 (hereinafter, also referred to as a washing device 100), in use, the washing device 100 may be put into a washing machine along with laundry, and when the washing machine washes the laundry, the washing device 100 may further wash the laundry by using ultrasonic waves generated by the washing device, thereby improving the washing capability of the washing machine. The washing device 100 exists independently of the washing machine, and is put into the washing machine only when clothes are washed, so that ultrasonic washing with low cost can be realized compared with a large-scale complex ultrasonic washing machine. The shape of the washing apparatus 100 is not particularly limited, and may be, for example, a spherical shape, a square shape, or the like, and is preferably a spherical shape in the present disclosure. The size of the washing device 100 is also not particularly limited, and may be portable and small relative to the size of the washing machine, for example, the spherical radius may be 15mm to 50 mm. In other examples, the washing device may be placed in other containers that may contain cleaning fluid, such as a basin, bucket, or the like. The type of the cleaning solution is not particularly limited, and the cleaning solution may be water alone or a solution of a chemical cleaning agent dispersed in water.

In some examples, the washing device 100 is capable of acting on a cleaning fluid, which may include: a body 1; a built-in power supply 2 provided in the body 1 to supply power to the washing apparatus 100; an ultrasonic wave generating device 3 electrically connected to the built-in power supply 2 and generating ultrasonic waves; a humidity-sensitive switch 4 provided on the main body 1 and controlling an electrical connection state between the built-in power supply 2 and the ultrasonic generator 3; and a water change reminding module 5, which comprises a turbidity sensor 53, wherein the turbidity sensor 53 is used for detecting the turbidity value of the cleaning liquid in the cleaning process of the washing device 100 in real time, and the water change reminding module 5 can send a water change reminding signal.

In some examples, the main function of the body 1 is to provide an external support function for the whole washing device 100, i.e. to facilitate the support/placement of various devices/elements of the washing device 100 to be placed. The shape and the material for production thereof are not particularly limited. The damping function of the damping structure is mainly embodied by an elastic material, the type of the elastic material is not particularly limited, and for example, the elastic material may be any one or a combination of silica gel, rubber, plastic and silicon rubber, and in the washing device 100, it is preferable that a layer of elastic silica gel is disposed outside the body 1 to form a damping structure, so as to reduce the vibration and abrasion of the washing device 100 in the washing machine. In other examples, the damping structure may be embodied by an elastic mesh, an elastic net, an internal spring, and the like.

In some examples, referring to fig. 3, the moisture sensitive switch 4 includes a first contact point 40 and a second contact point 41, both the first contact point 40 and the second contact point 41 being made of a metallic conductive material. The first contact point 40 and the second contact point 41 may be at the lower end and the upper end of the body 1, respectively. In the washing stage of the washing machine, after the washing device 100 is put into the washing machine, the humidity sensitive switch 4 immediately switches on the ultrasonic wave generating device 3 and the built-in power supply 2 after the washing machine discharges water until the first contact point 40 and the second contact point 41 are submerged simultaneously, and then the ultrasonic wave generating device 3 is started to generate ultrasonic waves; in the dewatering stage of the washing machine, the water is gradually removed, the first contact point 40 and the second contact point 41 are not conducted, and the washing device 100 stops generating the ultrasonic waves.

It should be noted that the presence of the humidity-sensitive switch 4 is in fact equivalent to enabling the washing apparatus 100 to be automatically activated or deactivated according to the washing mode of the washing machine. The clothes washing machine is very suitable for the daily use habit of consumers, namely, the clothes washing machine only needs to be put into the washing machine together with clothes.

In addition, the first contact point 40 and the second contact point 41 may have other shapes or configurations as long as they are sufficient for electrical conduction. The advantage of the first and second contacts 40 and 41 being at the lower and upper ends of the body 1 respectively is that this enables the moisture sensitive switch 4 to be rendered conductive only in the event that at least half of the washing apparatus 100 is submerged. Since if the two contact points are too close, it is likely that the washing apparatus 100 will be turned on to generate ultrasonic waves when only a small portion of the apparatus is submerged.

In some examples, referring to fig. 2, the aforementioned body 1 may be a spherical body, which may include an inner shell 10 and an outer shell 11 from inside to outside, the inner shell 10 may be structured to seal a cavity, and thus related devices/elements of the washing apparatus 100 may be disposed. For example, the internal power supply 2 and the ultrasonic generator 3 may be disposed in a sealed cavity of the inner housing 10, so as to achieve a waterproof function. The aforementioned outer casing 11 may be specifically provided with the aforementioned shock absorbing structure, that is, the whole outer casing 11 realizes the shock absorbing function of the washing device 100. Alternatively, the outer case 11 may be made of an elastic material. In addition, a plurality of friction protrusions 110 may be disposed on the outer shell 11, and when the outer shell 11 is made of silicone, the friction protrusions 110 are also silicone protrusions, that is, the friction protrusions 110 and the outer shell 11 may be integrally formed. The friction protrusion 110 is mainly used for friction washing of the laundry in the washing machine, and improves a washing effect. Of course, in other examples, the friction protrusion 110 may not be made of the same material as the outer housing 11, and will not be described herein.

In some examples, referring to fig. 3, the inner housing 10 may include a first inner housing 101 and a second inner housing 102. The first inner housing 101 and the second inner housing 102 may be two symmetrical hemispheres. The first inner housing 101 and the second inner housing 102 may be connected by a fastening member. The type of the fastening member is not particularly limited, and may be, for example, a screw, a bolt, and the like. A plurality of internally threaded holes 1020 may be formed in the second inner case 102, and a plurality of through holes 1010 corresponding to each of the internally threaded holes may be formed in the first inner case 101, and a fastening member (e.g., a screw) may be screwed into the internally threaded hole 1020 through the through hole 1010, thereby stably coupling the first inner case 101 and the second inner case 102. In addition, each through hole 1010 may be sealed, for example, by titrating a corresponding sealing glue, so that the inner housing 10 forms a hollow sealed cavity.

It is to be noted that the reason why the inner housing 10 is provided to detachably couple the first inner housing 101 and the second inner housing 102 is convenience of an assembly process or easy disassembly for maintenance. In other examples, inner housing 10 may also be integrally formed. The material of the inner housing 10 is not particularly limited, and ABS engineering plastic is preferable in the washing apparatus 100.

In some examples, the ultrasonic wave generating device 3 may include a driver and at least one transducer, which may be disposed at an upper end face 31 of the ultrasonic wave generating device 3. The driver can also be called a driving circuit, and may include an oscillation circuit, a power amplification circuit and an output matching circuit, which are electrically connected in sequence, wherein the oscillation circuit is configured to generate a specific frequency signal, the power amplification circuit is configured to amplify the specific frequency signal, and the output matching circuit is configured to transmit the specific frequency signal to the transducer so that the transducer generates an ultrasonic wave of a corresponding frequency.

The frequency of the ultrasonic wave generated by the transducer may be 20KHZ ~ 100KHZ, and the type of the transducer is not particularly limited, and examples thereof include an electromagnetic transducer, an electrostatic transducer, a mechanical ultrasonic transducer, a magnetostrictive transducer, and a piezoelectric transducer.

In some examples, the transducer may be disposed inside the inner housing 10, i.e., the entire transducer is within the sealed cavity of the inner housing 10 and protected by the seal. At this time, in consideration of attenuation characteristics during the propagation of the ultrasonic waves, the material of the inner housing 101 should ensure good sound transmission performance for the ultrasonic waves (i.e., small attenuation degree for the ultrasonic waves), which can be satisfied by the inner housing 10 made of ABS engineering plastic in the washing apparatus 100. In addition, the attenuation of the ultrasonic wave by the outer shell 11 is also considered, i.e. the material of the outer shell 11 should also have good sound transmission performance.

It is worth noting that the integral placement of the transducer within the inner housing 10 reduces the probability that the transducer may be damaged by impact or the like, while also avoiding the possibility of corrosion of the transducer by air/liquid or the like due to prolonged exposure.

Of course, referring to fig. 3, it will be appreciated that the transducer described above may also extend through the inner housing 10, for example when the transducer is a piezo ceramic transducer, the entire transducer may be inserted through/into the inner housing 10. The piezo ceramic transducer may include a vibrating end (not shown), which is a specific portion for generating ultrasonic waves, and the transducer is inserted/inserted into the inner housing 10, which is equivalent to exposing the vibrating end. Correspondingly, the outer shell 11 may have a flow guiding channel 111 thereon, and the piezoelectric ceramic transducer 30 (specifically, the vibrating end portion) may contact with water or the cleaning solution through the flow guiding channel 111. Namely, the vibration end part is exposed in water or cleaning liquid, so that the generated ultrasonic waves can directly act on the water or the cleaning liquid without loss, and the cleaning effect is good.

The number and size of the above-mentioned guide channels are not particularly limited, and it is preferable that one guide channel 111 having a size (cross-sectional area) approximately corresponding to the cross-sectional area of the vibration end of the transducer 30 is provided in the washing apparatus 100.

It is also worth noting that the specific penetration/embedding location of the transducers on the inner housing 10 is not particularly limited, nor is the number of transducers in this case.

In some examples, the water change reminding module 5 may be electrically connected to the internal power source 2 and communicatively connected to the ultrasonic wave generating device 3. The water change reminding module 5 is mainly made by arranging a singlechip and related peripheral functional chips or circuits on a circuit board (PCB). Specifically, the water change reminding module 5 may include a single chip microcomputer 50, an off-chip memory 51, a signal conditioning unit 52, a turbidity sensor 53, a D/a conversion unit 54, and an alarm reminder 55. The internal hardware structure of the water change reminding module 5 and the connection/communication relationship of each part can be seen in fig. 5.

In some examples, the type of the one-chip microcomputer 50 is not particularly limited as long as a micro size is satisfied. The off-chip memory 51 may store related control program instructions for the single-chip microcomputer 50 to retrieve. For example, the aforementioned control program instructions may include a timing program that automatically sets the wash time of the washing apparatus when the washing apparatus 100 is not in the washing machine, but is placed in a tub, bucket, or the like. The signal conditioning unit 52 is connected to the turbidity sensor 53 in a communication manner, and the signal conditioning unit 52 may also be called a signal conditioning circuit, and mainly conditions, such as filtering, amplifying, and performing analog-to-digital conversion on the signal transmitted from the turbidity sensor 53.

In addition, the D/a conversion unit 54 can convert the digital control signal from the single chip microcomputer 50 into an analog signal for directly controlling the alarm reminder 55 to initiate a water change reminder (alarm). For example, the single chip microcomputer 50 can be pre-programmed, once the turbidity value returned by the turbidity sensor 53 is greater than the preset turbidity threshold value, the single chip microcomputer 50 can control the alarm reminder 55 to send a water change reminding signal, namely, the turbidity of the cleaning liquid at the moment can influence the ultrasonic cleaning effect, and the cleaning is carried out again after the water change. At this time, the water change reminding module 5 can also send a control signal to the ultrasonic wave generating device 3 to stop generating the ultrasonic wave.

In some examples, the water change reminder module may further include a wireless communication unit 56, and the type of the wireless communication unit 56 is not particularly limited, and may be, for example, an infrared wireless communication type, a bluetooth communication type, a WIFI type, and a Radio Frequency (RF) type. Preferably a bluetooth wireless communication unit in the washing device 100. The wireless communication unit may include a signal receiver, a signal transmitter, and a signal processor. The signal receiver, the signal transmitter and the signal processor are also implemented by chips or circuits.

In addition, the wireless communication unit can be communicated or connected with a remote controller, a mobile phone, a PDA (palm computer) and other intelligent terminals. For example, in the washing apparatus 100, preferably controlled by a hand, the frequency and power of the ultrasonic waves required may vary, for example, depending on the amount of laundry to be washed. Therefore, the frequency or the power of the ultrasonic waves can be adjusted remotely through the wireless communication unit, and the device is very convenient.

Generally speaking, the ultrasonic washing device provided by the first aspect of the present disclosure has a small volume and is convenient to carry and use, and is independent from a washing machine or a laundry device, and when the washing machine is needed to wash clothes, the ultrasonic washing device can be put into the washing machine to perform auxiliary washing on the clothes by using ultrasonic waves, so that the washing capacity of the washing machine or the laundry device is improved. Meanwhile, the humidity-sensitive switch in the ultrasonic generator can automatically control the start and stop of the ultrasonic generator, so that the ultrasonic generator is more convenient for people to use. In addition, in the cleaning process, the turbidity value of the cleaning liquid can be detected in real time, and if the turbidity value is larger than a preset turbidity threshold value, the water change reminding module can send a water change reminding signal. The actual effect of ultrasonic cleaning is guaranteed not to be reduced.

Referring to fig. 1, a washing device charging base 200 is provided, and the washing device charging base 200 can charge the washing device 100. Thereby ensuring the sustainable use of the washing apparatus 100.

It is noted that, in some examples, the type, number and model of the built-in power source 2 are not particularly limited, and may be, for example, a dry battery, a lead storage battery, a lithium battery, a fuel cell, and the like, and preferably a rechargeable lithium battery in the washing apparatus 100. The charging method of the charging cradle 200 with respect to the internal power supply 2 is not particularly limited, and may be, for example, wireless charging or contact charging. The wireless charging method may include, for example, electromagnetic induction charging, magnetic resonance charging, and radio wave charging.

In some examples, the charging mode in the washing apparatus 100 is preferably contact charging, for example, referring to fig. 4 and 1, a contact ring 112 may be disposed on the inner casing 10, and the contact ring 112 may be used together with the first contact point 40 of the humidity-sensitive switch to realize contact charging. It can be seen that the first contact point 40 now in fact assumes two functions. This is mainly for the purpose of material saving, but in other examples, a contact tip, a contact piece, etc. may be provided for the contact ring piece 112 separately for contact charging.

In addition, two corresponding contact points 201 are provided on the charging base 200, and the charging base 200 can be connected to other power supply devices or commercial power. Thus, the washing device 100 is placed on the charging base 200, and the first contact point 40 and the contact ring 112 are respectively contacted with one contact point 201, so as to complete the charging of the internal power source 2.
