[0041] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.

[0042] Reference below Figure 1-Figure 11The mite removal device 100 according to the embodiment of the utility model is described, which can increase the weight of the core shaft 42 and change the weight distribution of the agitator element 4 through the supporting structure 5, thereby effectively solving the problem of shaking and dynamic imbalance caused by the suspension setting of the other end of the agitator element 4.

[0043] Combination Figure 1-Figure 11 As shown, the mite removal device 100 according to the embodiment of the utility model mainly includes a main body 1, a driving motor 2, a reduction mechanism 3, an agitator element 4 and a supporting structure 5.

[0044] Among them, the main body 1 mainly serves as a structural part of the outline of the mite removal device 100, playing a supporting and protective role; the driving motor 2 can provide the agitator element 4 with a driving force to stir dust mites and other dirt; the agitator element 4 can scrape and stir the mites, dust, hair, etc. on the surface to be cleaned and lift them from the cleaning surface; wherein, the reduction mechanism 3 can increase the torque at the input end of the agitator element 4 by reducing the speed of the output end of the driving motor 2, thereby providing the agitator element 4 with a stronger driving force and the required torque; the supporting structure 5 can increase the weight of the agitator element 4 and change the center of gravity position of the agitator element 4, thereby solving the problem of the agitator element 4 being prone to shaking and dynamic imbalance during operation.

[0045] Specifically, the main body 1 defines an agitator chamber 11, and the driving motor 2 is arranged in the main body 1. The reduction mechanism 3 is arranged in the main body 1, and one end of the reduction mechanism 3 is transmission-connected to the driving motor 2. The agitator element 4 is arranged in the agitator chamber 11. The agitator element 4 includes a stirring body 41 and a core shaft 42. A mounting groove 411 is formed at one end of the stirring body 41, and the core shaft 42 is arranged in the mounting groove 411. One end of the core shaft 42 is transmission-connected to the other end of the reduction mechanism 3, and the other end of the core shaft 42 is connected to the bottom of the mounting groove 411, and the other end of the stirring body 41 is suspended in the agitator chamber 11. The supporting structure 5 is arranged in the main body 1, and the supporting structure 5 extends into the mounting groove 411, the supporting structure 5 is sleeved on the core shaft 42, and the supporting structure 5 is supported on the inner circumferential wall of the mounting groove 411.

[0046] Specifically, a stirrer chamber 11 is defined in the main body 1 for stirring the stirrer element 4. The stirrer chamber 11 separates the stirrer element from other structures in the main body 1 to avoid the risk of mutual interference. The two ends of the speed reduction mechanism 3 respectively establish a transmission connection relationship with the drive motor 2 and the stirrer element 4, so that it is convenient to convert the high-speed and low-torque working condition at the drive motor 2 into the low-speed and high-torque working condition at the stirrer element 4, thereby improving the stirring force of the stirrer element 4.

[0047] Among them, the stirring body 41 surrounds the core shaft 42 in the circumferential direction, the core shaft 42 is arranged in the installation groove 411 in the axial direction, and one end of the core shaft 42 can establish a transmission connection relationship with the other end of the reduction mechanism 3, and the other end of the core shaft 42 is connected to the bottom of the installation groove 411. In this way, when the reduction mechanism 3 and one end of the core shaft 42 transmit each other, the other end of the core shaft 42 can transmit the transmission force to the agitator element 4, thereby achieving the effect of driving the agitator element 4 to stir and rotate.

[0048] Moreover, one end of the agitator element 4 is transmission-connected to the reduction mechanism 3, and the other end thereof is suspended in the agitator chamber 11, so that the agitator element 4 can achieve a cantilever support arrangement effect (referring to a situation where a structural element (such as a beam, plate, column, etc.) extends outward from its fixed point or support point without being directly supported at the other end), thereby adapting to the movement requirements of the specific agitator element 4 in this embodiment, solving the problem of space limitation in the agitator chamber 11, and thereby improving the rationality of the arrangement.

[0049] In addition, the supporting structure 5 in the main body 1 extends into the axially extending mounting groove 411 in the stirring body 41, and the supporting structure 5 is sleeved on the core shaft 42 along the axial direction, and the supporting structure 5 is also supported on the inner circumferential wall of the mounting groove 411, so that the supporting structure 5 is connected to the main body 1 and the agitator element 4 as a whole, and the weight of the agitator element 4 at the end connected to the reduction mechanism 3 can be increased (that is, the weight of the other free suspended end of the agitator element 4 is relatively light), so that additional weight can be added to the agitator element 4 to achieve the effect of improving the stability of the agitator element 4, and the possibility of deformation or imbalance of the agitator element 4 can be reduced by increasing the supporting structure 5 for the agitator element 4 (that is, changing the weight distribution on the agitator element 4 so that the center of gravity of the agitator element 4 is close to the side connected to the reduction mechanism 3), thereby solving the jitter and dynamic balance imbalance problems caused by the suspension setting of the other end of the agitator element 4 during operation.

[0050] Optionally, the agitator element 4 may include a first agitator element and a second agitator element arranged relatively along the lateral direction (ie, the left-right direction), so as to shorten the longitudinal (ie, the front-to-back direction) installation space, thereby improving the longitudinal space compactness of the overall structure of the mite remover 100.

[0051] Therefore, by setting up the mite removal device 100, it can increase the weight of the core shaft 42 through the supporting structure 5 and change the weight distribution of the agitator element 4, thereby effectively solving the problem of shaking and dynamic imbalance caused by the suspended setting of the other end of the agitator element 4.

[0052] According to some optional embodiments of the present invention, combined with Figure 1 , Figure 4 , Fig. 9 and Fig.10 As shown, the support structure 5 includes a mounting frame 51, a sleeve 52 and a bearing 53. The mounting frame 51 is arranged on the main body 1. One end of the sleeve 52 is arranged on the mounting frame 51, and the sleeve 52 is sleeved on the core shaft 42. The bearing 53 is supported between the sleeve 52 and the inner peripheral wall of the mounting groove 411.

[0053] In detail, the mounting frame 51 can be connected and fixed on the main body 1, thereby providing a stable support effect for the mounting frame 51; the sleeve 52 extends axially and is sleeved on the core shaft 42. The sleeve 52 mainly serves as an intermediary between the mounting frame 51 and the core shaft 42. The sleeve 52 avoids the risk of direct contact and friction between the core shaft 42 and the mounting groove 411 through its own wear-resistant material, thereby extending the service life of the core shaft 42; it can also help to accurately fix the position of the core shaft 42, prevent the core shaft 42 from unexpected axial or radial movement during operation, and ensure the operation of the core shaft 42 Stability and precision; it can also withstand the sliding movement between the core shaft 42 and the sleeve 52, reduce direct friction, and provide smooth rotation conditions; the bearing 53 is supported between the sleeve 52 and the inner circumferential wall of the mounting groove 411, so that a smooth interface can be provided between the rotating sleeve 52 and the stationary inner circumferential wall of the mounting groove 411, thereby greatly reducing the friction between the two, so that the core shaft 42 and the sleeve 52 can be smoothly rotated under the premise of supporting the sleeve 52 and the core shaft 42, thereby improving the smoothness of the agitator element 4 during the stirring operation.

[0054] Specifically, combined Figure 4 and Fig.10 As shown, the sleeve 52 includes a sleeve body 521 and an end plate 522. The sleeve body 521 is sleeved on the core shaft 42, the bearing 53 is arranged on the outer peripheral wall of the sleeve body 521, the end plate 522 is arranged at one end of the sleeve body 521, and the end plate 522 is arranged on the mounting frame 51.

[0055] It can be understood that the sleeve 521 extends in the axial direction and is sleeved on the outer peripheral wall of the core shaft 42, thereby replacing the core shaft 42 in contact with the bearing 53 to protect the core shaft 42; the end plate 522 is arranged at one axial end of the sleeve 521, and it mainly serves to connect the mounting frame 51, thereby improving the installation reliability between the sleeve 52 and the mounting frame 51.

[0056] Furthermore, combined with Figure 4 and Fig.10As shown, the mounting frame 51 is provided with a mounting hole, the end plate 522 is provided in the mounting hole, and the end plate 522 is interference fit with the mounting hole. That is to say, the mounting hole on the mounting frame 51 can form an interference fit mounting relationship with the end plate 522, and the interference fit generates elastic deformation between the two parts after assembly through a small interference amount between the end plate 522 and the mounting hole (the diameter of the end plate 522 is slightly larger than the diameter of the mounting hole), forming a close contact, thereby improving the tightness of the connection between the mounting frame 51 and the end plate 522 (able to withstand higher axial force, torque and dynamic load), avoiding the risk of mutual looseness between the mounting frame 51 and the end plate 522, and thus ensuring the stability of the long-term operation of the support structure 5.

[0057] Specifically, combined Figure 4 and Fig.10 As shown, the bearing 53 is multiple and includes a first bearing 531 and a second bearing 532. The first bearing 531 is supported at one end of the outer peripheral wall of the sleeve 52, and the second bearing 532 is supported at the other end of the outer peripheral wall of the sleeve 52. The first bearing 531 and the second bearing 532 are supported at both ends of the outer peripheral wall of the sleeve 52 in the axial direction, respectively. Such an arrangement can form a stable support effect on both ends of the sleeve 52 in the axial direction, and can also more evenly distribute the axial or radial load transmitted from the core shaft 42, and can also ensure the correct position of the sleeve 52 and the core shaft 42, thereby improving the support stability of the bearing 53 on the sleeve 52 and the core shaft 42.

[0058] Furthermore, combined with Figure 4 and Fig.10 As shown, a first axial stop portion 523 is provided on the sleeve 52 , and a second axial stop portion 4111 is provided on the inner peripheral wall of the mounting groove 411 . The first axial stop portion 523 and the second axial stop portion 4111 stop on opposite sides of the bearing 53 .

[0059] It can be understood that, in the axial direction of the bearing 53, the first axial stop portion 523 and the second axial stop portion 4111 can respectively form a stop and limit effect on the opposite sides of the bearing 53, thereby preventing the bearing 53 from moving unexpectedly on the sleeve 52, thereby ensuring the position stability of the bearing 53.

[0060] Optionally, combined Figure 4 , Fig. 9 and Fig.10As shown, an input member 421 is provided at one end of the mandrel 42, and a relief hole 511 is formed on the mounting frame 51. The mandrel 42 is passed through the relief hole 511, and the mandrel 42 is connected to the input member 421. The mandrel 42 is provided with an input member 421 for transmitting power at one end thereof close to the reduction mechanism 3 in the axial direction, and the relief hole 511 on the mounting frame 51 can be used to avoid the mandrel 42, so that the mandrel 42 can smoothly pass through the mounting frame 51 and establish a transmission connection relationship with the input member 421, thereby achieving the effect of driving the stirring body 41 to perform stirring action.

[0061] Alternatively, combining Figure 4 , Fig. 9 and Fig.10 As shown, an input member 421 is provided at one end of the mandrel 42, a avoidance hole 511 is formed on the mounting frame 51, a receiving groove is formed on the shaft sleeve 52, the reduction mechanism 3 is passed through the avoidance hole 511, and the mandrel 42 is connected with the input member 421 in the receiving groove. Among them, an input member 421 for transmitting power is provided at one end of the mandrel 42 axially close to the reduction mechanism 3, the reduction mechanism 3 can pass through the avoidance hole 511, and the receiving groove of the shaft sleeve 52 can provide a receiving space for the part of the structure of the reduction mechanism 3 passing through the avoidance hole 511, and the part of the mandrel 42 located in the receiving groove establishes a transmission connection relationship with the reduction mechanism 3, thereby achieving the effect of transmitting the driving force from the reduction mechanism 3 to the agitator element 4, and then the agitator element 4 achieves the effect of stirring dust mites.

[0062] Specifically, combined Figure 9-11 As shown, a limiting groove 12 is formed at one end of the agitator chamber 11 of the main body 1, and a limiting portion 512 is provided on the mounting frame 51. The limiting groove 12 and the limiting portion 512 cooperate in the axial and / or circumferential limiting of the agitator element 4. Such an arrangement can limit the positional relationship between the main body 1 and the mounting frame 51, thereby ensuring the positional stability of the mounting frame 51 on the main body 1 and preventing the risk of relative shaking between the mounting frame 51 and the main body 1.

[0063] Furthermore, combined with Fig.11 As shown, the limiting groove 12 is formed on opposite sides of one end of the agitator chamber 11, and the limiting portion 512 is arranged on opposite sides of the mounting frame 51. The limiting groove 12 and the limiting portion 512 correspond one-to-one in the axial and / or circumferential limiting cooperation of the agitator element 4.

[0064] For example, along the longitudinal direction (that is, the front-to-back direction), limiting grooves 12 are formed on the opposite sides of the agitator chamber 11, and limiting portions 512 corresponding to the limiting grooves 12 are formed on the opposite sides of the mounting frame 51. The limiting grooves 12 and the limiting portions 512 are matched in a limiting manner along the axial direction. In this way, the limiting points of the mounting frame 51 and the main body 1 can be increased, thereby enhancing the installation stability between the two.

[0065] Specifically, combined Figure 2 , Figure 7 and Fig.11 As shown, the main body 1 includes a casing 13 and a pressure plate 14. The casing 13 forms a stirrer chamber 11, and the casing 13 forms an opening 131 below the stirrer chamber 11. The pressure plate 14 is arranged at the opening 131, and the pressure plate 14 abuts against the mounting frame 51, and the pressure plate 14 is connected to the casing 13.

[0066] That is to say, the housing 13 can serve as the main outer contour structure of the main body 1, which plays the role of protecting the internal structure and providing support and installation. The housing 13 is formed with an agitator chamber 11 on the side facing the surface to be cleaned (the agitator chamber 11 separates the agitator element 4 from other elements in the housing 13). The agitator chamber 11 can be specifically used to provide a stirring working environment for the agitator element 4. Since the agitator element 4 needs to contact the surface to be cleaned, the housing 13 is formed with an opening 131 below the agitator chamber 11, so that the agitator element 4 in the agitator chamber 11 can pass through the opening 131 and contact the surface to be cleaned, thereby smoothly achieving the stirring of dust mites. Among them, the pressure plate 14 is buckled at the opening 131. The pressure plate 14 can provide a certain degree of protection for the agitator element 4 without interfering with the agitator element 4 contacting the surface to be cleaned. The pressing plate 14 is in abutment with the mounting frame 51 , and the pressing plate 14 is connected to the housing 13 , so that the mounting frame 51 , the pressing plate 14 and the housing 13 are connected as a whole, thereby enhancing the relative position stability and structural reliability.

[0067] Furthermore, combined with Figure 4 , Figure 5 , Fig. 9 and Fig.10 As shown, the speed reduction mechanism 3 includes a first transmission wheel 31, a second transmission wheel 32 and a transmission belt 33. The first transmission wheel 31 is in transmission connection with the driving motor 2, the second transmission wheel 32 is arranged at one end of the agitator element 4, the transmission belt 33 is sleeved on the first transmission wheel 31 and the second transmission wheel 32, the first transmission wheel 31 transmits power to the second transmission wheel 32 through the first transmission wheel 31, and the second transmission wheel 32 is in transmission connection with the core shaft 42.

[0068] Among them, the speed reduction mechanism 3 can increase the torque of the output end (agitator element 4) by reducing the rotation speed of the input end (drive motor 2), thereby providing a stronger driving force and the required torque for the agitator element 4, thereby ensuring the stirring force of the agitator element 4.

[0069] For example, the first transmission wheel 31 is smaller than the second transmission wheel 32, and the first transmission wheel 31 is equivalent to a driving wheel, and the second transmission wheel 32 is equivalent to a driven wheel. When the first transmission wheel 31 rotates, the driving force is transmitted to the second transmission wheel 32 through the transmission belt 33, and the second transmission wheel 32 transmits the power to the core shaft 42. Such a transmission arrangement can ensure the accuracy of the transmission ratio between the first transmission wheel 31 and the second transmission wheel 32, and also provide a power transmission route between the first drive motor 2 and the first agitator element 4, thereby improving the transmission reliability and transmission rationality.

[0070] Specifically, combined Figure 4 and Fig. 9 As shown, the speed reduction mechanism 3 further includes an output member 34 and a shaft body 35 . An input member 421 is disposed at one end of the core shaft 42 , and the output member 34 is in transmission cooperation with the input member 421 . The second transmission wheel 32 and the output member 34 are disposed on the shaft body 35 .

[0071] It can be understood that the second transmission wheel 32 and the output member 34 are sleeved on the axial ends of the shaft 35. The second transmission wheel 32 can transmit power to the shaft 35. The shaft 35 smoothly transmits the transmission force from the reduction mechanism 3 to the agitator element 4 through the cooperation relationship between the output member 34 and the input member 421, thereby ensuring the power transmission effect between the reduction mechanism 3 and the agitator element 4.

[0072] Furthermore, combined with Fig. 9 and Fig.10 As shown, the mite removal device 100 further includes a bracket 6 and a third bearing 7. The bracket 6 is arranged on the main body 1, the third bearing 7 is arranged on the bracket 6, the shaft 35 passes through the third bearing 7, and the second transmission wheel 32 and the output member 34 are located on opposite sides of the third bearing 7.

[0073] That is to say, the bracket 6 is connected between the main body 1 and the third bearing 7, so that the main body 1, the bracket 6 and the third bearing 7 can be connected as a whole, so as to provide stable support and installation conditions for the third bearing 7. Among them, the shaft body 35 passes through the third bearing 7, and the second transmission wheel 32 and the output member 34 are respectively located on the opposite sides of the third bearing 7 in the axial direction. Such an arrangement can improve the running stability of the shaft body 35, and can also make the power on the shaft body 35 be transmitted by the second transmission wheel 32 at one end and the output member 34 at the other end (that is, the driving force is transmitted along the axial span of the shaft body 35). The third bearing 7 can also be used to separate the second transmission wheel 32 and the output member 34 in the axial direction, so as to form a certain axial limit effect on the above two, thereby improving the rationality of the arrangement.
