[0038] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.

[0039] Reference below Figure 1-Figure 7 The dust mite removal device 100 according to the embodiment of the utility model is described, which realizes efficient and continuous suction work on dust mites through a brushless motor, and can improve the running smoothness and accuracy of the suction work.

[0040] Combination Figure 1-Figure 7 As shown, the mite removal device 100 according to the embodiment of the utility model includes a main body 1, a stirrer element 2, a dust cup 3 and a suction motor 4.

[0041] Among them, the main body 1 mainly serves as a structural part of the outline of the mite remover 100, playing a supporting and protective role; the agitator element 2 can scrape and stir the mites, dust, lint, etc. on the surface to be cleaned and bring them up from the cleaning surface; the dust cup 3 can be detachably installed on the main body 1 to facilitate the collection and dumping of mites, dust, lint, etc. brushed up by the agitator element 2, and the gas can be filtered and discharged; the suction motor 4 can suck the dust mites stirred up by the agitator element 2 and collect the dirt to achieve a cleaning effect.

[0042] Specifically, the main body 1 defines a stirrer chamber 11, and the stirrer chamber 11 has a suction port 111 and an exhaust port 112. The stirrer element 2 is disposed in the stirrer chamber 11. The dust cup 3 is detachably disposed above the main body 1, and the dust cup 3 is communicated with the exhaust port 112. The suction motor 4 is disposed in the main body 1, and the suction motor 4 is located behind the stirrer chamber 11, and the suction motor 4 is communicated with the dust cup 3. Among them, the suction motor 4 is a brushless motor.

[0043] Furthermore, at least part of the agitator element 2 is connected to the surface to be cleaned through the suction port 111, and the dust cup 3 is provided with an exhaust port 112 connected to the agitator chamber 11. In the process of cleaning dust mites, the agitator element 2 picks up and stirs the dirt and hair on the surface to be cleaned and is guided to the exhaust port 112 under the suction action of the suction motor 4, and then transported to the dust cup 3 through the suction pipe, thereby achieving the effect of dust removal and collection. Among them, the suction motor 4 is located behind the agitator chamber 11, so that it can reasonably form an arrangement relationship with the agitator chamber 11 in the front-to-back direction, making full use of the longitudinal space in the main body 1, so that the internal structure of the dust mite removal device 100 is more regular and orderly.

[0044] In addition, the suction motor 4 adopts a brushless motor. A brushless motor is a motor that uses electronic commutation rather than mechanical carbon brushes for current switching. Compared with a traditional brushed motor, a brushless motor has no physical contact with carbon brushes and commutators when working. It mainly generates a constant magnetic field through the permanent magnets on the rotor and a variable magnetic field through the stator coil when current passes through. The interaction between the two drives the rotor to rotate. In this way, the signal provided by the rotor position sensor (such as a Hall effect sensor) is constantly changed. The current direction in the stator coil is switched in time to maintain the continuous rotation of the rotor, thereby controlling its rotational force (torque) to always maintain a high value, thereby ensuring that the dust mite removal device 100 continues to efficiently perform the cleaning work of sucking out dust mites.

[0045] Moreover, since the brushless motor has no energy loss caused by mechanical friction and brush sparks during operation, it runs more smoothly, generates less noise and electromagnetic interference, reduces maintenance requirements, prolongs the service life of the motor, and makes it faster and more accurate when receiving control instructions for starting, stopping and speed regulation. In summary, the mite removal device 100 uses a brushless motor as the suction motor 4, which can effectively improve the working efficiency and working stability of the mite removal device 100 during the suction process.

[0046] Therefore, by providing the dust mite removal device 100, efficient and continuous suction work can be achieved on dust mites through the brushless motor, and the running smoothness and accuracy of the suction work can be improved.

[0047] According to some optional embodiments of the present invention, combined with Figure 5 and Figure 6 As shown, the mite removal device 100 also includes a high-voltage power line 5, which is electrically connected to the suction motor 4. Specifically, the high-voltage power line 5 can be electrically connected between the power supply and the suction motor 4, so as to transmit power to the suction motor 4, and in the process of transmitting power, the high-voltage power line 5 has a small power loss due to its own small resistance, thereby improving the power transmission efficiency.

[0048] Furthermore, combined with Figure 5 and Figure 6 As shown, the rectifier circuit 6 is electrically connected to the high-voltage power line 5 and the suction motor 4, respectively. That is to say, the rectifier circuit 6 is electrically connected between the high-voltage power line 5 and the suction motor 4. As a circuit configuration, the rectifier circuit 6 mainly plays the role of converting AC power into DC power, so that the normal operation of the brushless motor can be stably guaranteed (for example, in the scenario where the brushless motor needs rapid acceleration, deceleration or precise position control, DC power can provide better dynamic response and control accuracy; and DC power is also easier to accurately control the voltage and current of the brushless motor), thereby ensuring the stability and efficiency of the suction work.

[0049] Furthermore, combined with Figure 5 and Figure 6 As shown, the rectifier circuit 6 includes a transformer 61, a rectifier main circuit 62 and a filter 63. The transformer 61 is electrically connected to the high voltage power line 5, the rectifier main circuit 62 is electrically connected to the transformer 61, and the filter 63 is electrically connected to the rectifier main circuit 62 and the suction motor 4 respectively.

[0050] It can be understood that the transformer 61 is electrically connected between the high-voltage power line 5 and the rectifier main circuit 62, and the filter 63 is electrically connected between the rectifier main circuit 62 and the suction motor 4. When the suction motor 4 is working, the current passes through the power supply, the high-voltage power line 5, the rectifier main circuit 62, the transformer 61, the filter 63 in sequence and finally flows to the suction motor 4, thus realizing a complete power connection path for the suction motor 4.

[0051] Among them, the transformer 61 can convert the voltage of the input circuit into the voltage required by the output circuit, and the voltage can be increased or decreased by changing the turns ratio of the primary coil and the secondary coil; the rectifier main circuit 62 can be used to convert AC power into DC power; the filter 63 can reduce the AC component in the pulsating DC voltage to make the output voltage smoother, and can also filter out electromagnetic signals of a specified frequency, thereby reducing electromagnetic interference and protecting electronic equipment from external interference sources. In summary, the rectifier circuit 6 can ensure the working stability of the suction motor 4.

[0052] According to some embodiments of the present invention, Figure 4 and Figure 5 As shown, the suction motor 4 has a suction outlet 41, and the main body 1 is provided with an air outlet 12. The mite removal device 100 further includes a heating device, which is provided on the main body 1 and selectively heats the wind flowing from the suction outlet 41 to the air outlet 12.

[0053] In detail, the suction motor 4 can finally discharge the sucked air from its own suction outlet 41, thereby achieving the exchange and circulation effect of the gas inside and outside the suction motor 4, thereby ensuring the continuous suction effect of the suction motor 4. Among them, the main body 1 is formed with an air outlet 12 that is interconnected with the suction outlet 41, so that the air discharged from the suction outlet 41 can be smoothly discharged to the outside of the main body 1 through the air outlet 12, thereby forming a continuously circulating suction airflow and improving the suction efficiency.

[0054] In addition, the heating device on the main body 1 can selectively heat the wind flowing from the suction outlet 41 to the air outlet 12, so that a small number of harmful bacteria existing in the wind can be heated and inactivated, thereby improving the air purification rate.

[0055] Furthermore, the heating device is a heating wire or a PTC heater. For example, when current passes through the heating wire, heat is generated, thereby efficiently converting electrical energy into thermal energy, thereby heating the nearby air. For another example, when current passes through a PTC heater (usually a high-voltage electric drive), due to the characteristics of the PTC thermistor (the resistance value increases with the increase in temperature, and the PTC heater can automatically adjust when overheated to prevent overheating), the efficiency and safety of the heating process are taken into account.

[0056] According to some embodiments of the present invention, Figure 3 and Figure 6 As shown, the agitator element 2 includes a first agitator element 21 and a second agitator element 22 , the first agitator element 21 and the second agitator element 22 are arranged in the agitator chamber 11 , and the first agitator element 21 and the second agitator element 22 are arranged opposite to each other in the lateral direction of the mite removal device 100 .

[0057] Among them, the first agitator element 21 and the second agitator element 22 are arranged opposite to each other in the horizontal direction (that is, in the left-right direction), which can also shorten the installation space in the longitudinal direction (that is, in the front-to-back direction), thereby improving the longitudinal space compactness of the overall structure of the mite removal device 100. Moreover, compared with the mite removal device with agitator elements arranged side by side or in a single row in the longitudinal direction, the embodiment of the present application can increase the cleaning coverage area in contact with the cleaning surface while realizing the coordinated control of the first agitator element 21 and the second agitator element 22 to perform cleaning work, thereby improving the work efficiency of each cleaning and completing the cleaning task of a large area more quickly.

[0058] Specifically, combined Figure 3 As shown, the first agitator element 21 and the second agitator element 22 are symmetrically arranged with respect to a vertical center plane perpendicular to the horizontal direction of the mite removal device 100 .

[0059] It can be understood that such an arrangement can improve the uniformity of the stirring action of the mite remover 100 on both sides along the lateral direction when it is working, avoid the problem of uneven dust suction and mite removal effect when the first agitator element 21 and the second agitator element 22 are cleaning the dirt on the cleaning surface, and can also make the structure inside the main body 1 more regular and orderly, which is convenient for improving processing and manufacturability.

[0060] Furthermore, combined with Figure 3 As shown, the central axis of the first agitator element 21 and the central axis of the second agitator element 22 are both inclined relative to the bottom surface of the mite removal device 100.

[0061] Among them, the central axis of the first agitator element 21 is inclined toward the bottom surface from one end thereof (i.e., the end of the first agitator element 21 away from the second agitator element 22) to the other end (i.e., the end of the first agitator element 21 close to the second agitator element 22), and the central axis of the second agitator element 22 is inclined relative to the bottom surface of the mite removal device 100 from one end thereof (i.e., the end of the second agitator element 22 away from the first agitator element 21) to the other end (i.e., the end of the second agitator element 22 close to the first agitator element 21), so that the first agitator element 21 and the second agitator element 22 are constructed with a double-conical structure relative to the bottom surface. When the inclined first agitator element 21 and the second agitator element 22 are wound around the hair during operation, the hair will form a component force along the inclined surface, and the height distances of the hair at different sections in the lateral direction of the agitator element 2 are different, so that the hair is less likely to accumulate into continuous bundles and be wound around the agitator element 2, thereby solving the problem of hair entanglement on the first agitator element 21 and the second agitator element 22.

[0062] Furthermore, the angle between the central axis of the first agitator element 21 and the bottom surface of the mite removal device 100 is α1, and α1 satisfies: 0°<α1≤15°; and / or the angle between the central axis of the second agitator element 22 and the bottom surface of the mite removal device 100 is α2, and α2 satisfies: 0°<α2≤15°.

[0063] For example, the angle α1 between the central axis of the first agitator element 21 and the bottom surface of the mite removal device 100 is small, so that the problem of hair entanglement on the first agitator element 21 can be solved while ensuring that the first agitator element 21 contacts the cleaning surface. For example, α1 can be 5°, 8°, 10° or 15°, but is not limited thereto.

[0064] For another example, the angle α2 between the central axis of the second agitator element 22 and the bottom surface of the mite removal device 100 is small, so that the problem of hair entanglement on the second agitator element 22 can be solved while ensuring that the second agitator element 22 contacts the cleaning surface. For example, α1 can be 5°, 8°, 10° or 15°, but is not limited thereto.

[0065] Optionally, combined Figure 3 As shown, the mite removal device 100 further includes a first drive motor 8 and a second drive motor 9. One end of the first agitator element 21 is in driving connection with the first drive motor 8. One end of the second agitator element 22 is in driving connection with the second drive motor 9.

[0066] Among them, the first drive motor 8 and the second drive motor 9 are respectively connected to each other with one end of the first agitator element 21 and one end of the second agitator element 22, so that the first drive motor 8 and the second drive motor 9 can respectively drive the first agitator element 21 and the second agitator element 22 to remove dust and mites. Such an arrangement can achieve the first agitator element 21 and the second agitator element 22 to stir at different speeds and in different directions at the same time, and can also achieve the situation where only one agitator element 2 is stirred at the same time while the other agitator element 2 is kept stationary, thereby effectively increasing the dust and mite removal scenarios of the mite removal device 100.

[0067] In addition, compared with a single-drum mite remover (that is, a mite remover with only one agitator element and one drive motor), the embodiments of the present application can effectively increase the use scenarios of the mite remover 100 and improve the power supply for dust removal; compared with a single-motor mite remover with agitator elements arranged side by side longitudinally, the embodiments of the present application can independently control the first agitator element 21 and the second agitator element 22 for dust removal, and the first agitator element 21 and the second agitator element 22 are arranged opposite to each other in the horizontal direction (that is, the left and right direction), which can save longitudinal (that is, the front and back direction) installation space, improve the spatial compactness of the overall structure, and improve the efficiency of dust removal and mite removal.

[0068] Alternatively, combining Figure 7 As shown, the mite removal device 100 also includes a driving motor 10, which has a first power output end 101 and a second power output end 102. One end of the first agitator element 21 is transmission connected to the first power output end 101 of the driving motor 10, and one end of the second agitator element 22 is transmission connected to the second power output end 102 of the driving motor 10.

[0069] Among them, the first power output end 101 and the second power output end 102 of the driving motor 10 are respectively connected to one end of the first agitator element 21 and the second agitator element 22. With such an arrangement, when the driving motor 10 starts working, it can simultaneously drive the first agitator element 21 and the second agitator element 22 to perform cleaning actions. Compared with the mite removal device with a single motor and a single roller brush, the embodiment in this case can also increase the cleaning coverage area in contact with the cleaning surface under the premise that only the single driving motor 10 provides driving force, thereby improving the work efficiency of each cleaning and completing large-area cleaning tasks more quickly; it can also penetrate deeper into the fabric fibers, effectively loosen and absorb tiny particles such as mites, dandruff, and dust, thereby improving the deep cleaning ability of the mite removal device 100. In addition, the transmission system arrangement of the single driving motor 10 can reduce the mechanical parts and electronic components inside the main body 1, thereby simplifying the overall structure and improving practicality and economy.
