Referring to fig. 1 to 3, fig. 1 is a schematic structural view of an acarid killing device in one or more embodiments, fig. 2 is a schematic exploded structural view of the acarid killing device shown in fig. 1, and fig. 3 is a schematic structural view of a radio frequency device in one or more embodiments. An embodiment of the present application provides an acarid killing device 100, which includes a body 10 and a radio frequency device 20.

The body 10 may include a housing 11, a dust cup assembly 12, and a dust collection assembly, where the dust collection assembly is accommodated in the housing 11, the dust cup assembly 12 is communicated with the dust collection assembly and mounted on the housing, and the dust collection assembly is used for providing suction to absorb dust, mites, and other wastes outside to the dust cup assembly 12, and the dust cup assembly 12 is used for collecting the garbage. Specifically, the housing 11 includes an upper case 111 and a lower case 112, and a receiving chamber for receiving the dust collection assembly is formed between the upper case 111 and the lower case 112. The radio frequency device 20 may also be housed within the receiving cavity.

Referring to fig. 4, the body 10 has an mite removal side 13. The mite removing side 13 is a side portion on which the mite removing device 100 can act on the object to be removed to achieve a mite removing function when the mite removing device is operated. In the embodiment of the present application, the mite removal side 13 is provided at the bottom of the main body 10, and in other embodiments, the mite removal side 13 may be provided at the side of the main body 10. Specifically, the mite removal side 13 is provided on the lower case 112.

The radio frequency device 20 is mounted on the body 10, the radio frequency device 20 has a radiation end 21, the radiation end 21 is exposed on the mite removing side 13, and the radio frequency device 20 is used for radiating high-frequency electromagnetic waves outwards through the radiation end 21.

In practical application, when the high-frequency electromagnetic wave radiated by the rf device 20 reaches the object to be removed, such as bedding, because the living things like mites and bacteria are composed of complex compounds like water and proteins, the water content in the living cells is 75% to 85%, and the water molecules have extremely strong polarity, the energy of the high-frequency electromagnetic wave can be absorbed to raise the temperature of the living things, so that the proteins of the living things like mites and bacteria are influenced, the protein space structures in the living things like mites and bacteria are forced to change or be destroyed, and a series of chain reactions occur to lose the biological activity. Thus, a preferable mite removal effect can be achieved.

Meanwhile, when other abiotic parts in the mite-removing object contain moisture, the energy of high-frequency electromagnetic waves can be absorbed to improve the temperature of the mite-removing object, so that the temperature of the bedding is improved, and the effect of drying the bedding is achieved.

Therefore, by providing the radio frequency device 20 on the mite removal instrument 100, not only the mites and bacteria on the surface of the object but also the mites and bacteria inside the object can be removed, and thus the effect of mite removal and sterilization is improved. In addition, the radio frequency device 20 radiates high-frequency electromagnetic waves with greater energy, so that the effect of removing mites and sterilizing in a short time is also better.

Referring to fig. 3, in the embodiment of the present application, the rf device 20 is electrically connected to an rf source 22, an rf power amplifier 23 and an rf module 24 in sequence. The rf source 22 is used for generating ac power, the rf power amplifier 23 is used for amplifying the power of the ac power to a target power, the rf module 24 has a radiation end 21, and the rf module 24 is used for converting the ac power having the target power into high-frequency electromagnetic waves.

The rf source 22 being configured to generate ac power means that the rf source 22 is capable of generating ac power upon power. Specifically, the RF source 22 is capable of switching on DC power and converting to AC power.

In an embodiment of the present application, the radio frequency source 22 comprises a crystal oscillator. The crystal oscillator can convert direct current into alternating current with a certain frequency range, so that high-frequency electromagnetic waves with better frequency can be selected, the mite removing effect is improved, and the damage to human bodies is reduced.

In particular, in the embodiment of the present application, the frequency range of the high-frequency electromagnetic wave is 1MHz to 100MHz.

It is found that when the frequency of the high-frequency electromagnetic wave is lower than 1MHZ, the radio frequency penetrability is too strong to concentrate, so that the mite-removing and sterilizing effects are poor. When the frequency of the high-frequency electromagnetic wave exceeds 100MHz, the penetrability is weak, the concentration capacity in unit area is strong, and once the operation is improper, certain damage is caused to the human body. Therefore, the frequency range of the high-frequency electromagnetic wave is 1MHz to 100MHz, so that the better mite-killing and sterilizing effects can be realized, and the damage to human bodies is lower.

It should be noted that although the rf device 20 is used for mite-killing sterilization by high-frequency electromagnetic waves, the rf device is less harmful to the human body because the rf device is lower in frequency than ultraviolet and far infrared.

In an embodiment of the present application, the target power ranges from 10W to 1000W.

By setting the range of the target power to 10W to 1000W, the power requirements of the limited acarid remover and the wireless acarid remover can be met.

Thus, by arranging the radio frequency source 22, the radio frequency power amplifier 23 and the radio frequency module 24, the external power supply can be successfully converted into the required high-frequency electromagnetic wave, and the structure is simple and reliable.

As shown in fig. 4 to 6, the radio frequency module 24 further includes a protective cover 241 and a radio frequency antenna 242. The rf antenna 242 is electrically connected to the rf power amplifier 23, and the rf antenna 242 is accommodated in the protective cover 241.

The rf antenna 242 can radiate high-frequency electromagnetic waves outward, and a portion of the protective cover 241 has characteristics such that the high-frequency electromagnetic waves are not penetrated and/or the high-frequency electromagnetic waves are absorbed in a small amount, thereby preventing accidental injury to a human body. In addition, the protective cover 241 also protects the rf antenna 242 from the external environment.

Specifically, the protective cover 241 has a transparent portion 2411, and high-frequency electromagnetic waves are radiated outward from the transparent portion 2411.

By providing the transparent portion 2411, the high-frequency electromagnetic wave can be radiated only from the transparent portion 2411, and thus, the radiation range is defined in a simple manner.

In some embodiments, the interior of the protective cover 241 has a reflective portion disposed on the outer periphery of the transparent portion 2411.

By providing the reflection portion, the protective cover 241 is not penetrated by the high-frequency electromagnetic wave, and the high-frequency electromagnetic wave can be radiated only from the transparent portion 2411, thereby preventing accidental injury to the human body.

Alternatively, the reflective portion is disposed around the transparent portion 2411. By the surrounding form, the high-frequency electromagnetic wave can be further reflected intensively to the transparent portion 2411, reducing the loss of the high-frequency electromagnetic wave.

Alternatively, the reflective portion may be formed inside the protective cover 241 by coating a reflective material, or by sticking reflective paper, etc

In other embodiments, some wave absorbing material may be coated on the inner side of the protective cover 241 to consume energy of the high-frequency electromagnetic wave, which is not particularly limited.

In the embodiment of the present application, the protective cover 241 is tapered, and the transparent portion 2411 is provided at the bottom of the protective cover 241.

Note that the bottom of the protective cover 241 having a tapered shape means a portion of the protective cover 241 having a larger-sized end.

In this way, the high-frequency electromagnetic wave can be emitted so as to diverge toward the transparent portion 2411 along the inner wall of the protective cover 241, and the radiation range is increased.

Specifically, the protective cover 241 may be in a quadrangular pyramid shape, and in other embodiments, may be in a conical shape or other polygonal pyramid shapes, and is not particularly limited.

Further, the reflecting portion is provided on the inner peripheral side wall of the cone-shaped protection cover 241.

In particular, in the embodiment of the present application, the protection cover 241 includes a transparent plastic plate, where the transparent plastic plate forms the transparent portion 2411, and the protection cover 241 further includes a cone-shaped cover 2412, where the cone-shaped cover 2412 and the transparent plastic plate can enclose to form a containing cavity for containing the rf antenna 242.

Referring to fig. 6 and 7, in some embodiments, one of the rf module 24 and the body 10 includes a buckle 243, and the other has a buckle slot 14, and the buckle 243 is engaged with the buckle slot 14 to fix the rf module 24 to the body 10.

The mode of matching and fixing by arranging the buckle 243 and the buckle groove 14 is simple. In other embodiments, the fixing may be performed by a screw hole or the like, and is not particularly limited.

Referring to fig. 4 and 8, in some embodiments, the mite removal device 100 further includes a temperature sensor 30, where the temperature sensor 30 is disposed on the mite removal side 13 for detecting an ambient temperature to start or stop the rf device.

Specifically, in actual operation, before the mite removing device 100 is to remove mites, the mite removing side 13 of the mite removing device 100 is closely attached to the surface of the mites to be removed, and the temperature sensor 30 can detect the temperature of the mites to be removed at this time, so as to determine whether the mite removing operation can be performed, for example, if the detected temperature does not reach the set value, the radio frequency device 20 can be started, otherwise, the radio frequency device 20 is stopped.

Secondly, the temperature sensor 30 can also detect the ambient temperature in real time when the mite removal operation is performed, and can stop the rf device 20 when the temperature rises to a set value or a set range, thereby avoiding burn by mites.

It should be noted that, after the radio frequency device 20 of the present application is stopped, it can be stopped, and there is no phenomenon of temperature rising inertia, so that the protection of the mites to be removed is better.

In some embodiments, the mite removal instrument 100 further includes a distance sensor 40, the distance sensor 40 being provided on the mite removal side 13 for detecting a distance from the mite to be removed to activate or deactivate the radio frequency device 20.

Specifically, in actual operation, before the mite removing device 100 is to perform the mite removing operation on the mite to be removed, the mite removing side 13 of the mite removing device 100 is closely attached to the surface of the mite to be removed, and at this time, the distance sensor 40 detects the distance between the mite to be removed, so as to determine whether the mite removing operation can be performed, for example, if the detected distance reaches the set value or the set range, the radio frequency device 20 can be started, otherwise, the radio frequency device 20 is stopped.

Secondly, the distance sensor 40 can also detect the distance in real time when the mite removal operation is performed, and the radio frequency device 20 can be stopped when the distance rises to a set value or a set range, thereby avoiding the damage of the high frequency electromagnetic wave to the human body and improving the safety of the mite removal instrument 100.

In other embodiments, the mite controller 100 may include both a temperature sensor 30 and a distance sensor 40 to enable or disable the RF device 20 through the common detection of the temperature sensor 30 and the distance sensor 40.

In some embodiments, the mite controller 100 further includes a controller 50 communicatively coupled to the RF device 20, the temperature sensor 30, and/or the distance sensor 40, wherein the controller 50 can activate or deactivate the RF device 20 based on the detection result of the temperature sensor 30 and/or the distance sensor 40.

In some embodiments, the radiating end of the RF device 20 includes a receiving end and a transmitting end, the receiving end and the transmitting end being spaced apart from one another.

The rf module 24 includes a plurality of rf antennas 242, wherein at least one rf antenna 242 is a transmitting end, wherein at least one other rf antenna 242 is a receiving end, a magnetic field is formed between each transmitting end and a corresponding receiving end, so as to form a high-frequency electromagnetic wave in a corrugated form, and the mite to be removed is included in the coverage range of the high-frequency battery wave.

In the embodiment of the present application, the rf module 24 includes two rf antennas 242, wherein one of the rf antennas 242 is a transmitting end, and the other rf antenna 242 is a receiving end, and the two rf antennas 242 are spaced apart from each other.

Further, the temperature sensor 30 is disposed between the receiving end and the transmitting end. The temperature sensor 30 is arranged between the radio frequency devices 20, so that the accuracy of temperature detection can be improved, and the reliability of protecting the mites to be removed can be further improved.

In some embodiments, the distance sensors 40 also include at least two, all of the distance sensors 40 being spaced apart from one another. In this way, the reliability of distance detection can be improved.

Alternatively, all of the distance sensors 40 are provided on the outer periphery of all of the radio frequency antennas 242.

For a more detailed understanding of the present application, the working principle of the mite controller 100 is given below:

after the distance sensor 40 and the temperature sensor 30 detect no abnormality, the controller 50 starts the power supply, then the direct current is supplied to the voltage control crystal oscillator, the voltage control crystal oscillator converts the direct current into alternating current with the frequency in the range of 1MHz to 300MHz, then the power of the radio frequency is adjusted to be between 10W and 1000W by passing through the radio frequency power amplifier 23, and finally a radiation electric field is formed by the radio frequency module 24 to radiate high frequency electromagnetic waves.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
