[0002] The main types of washing machines currently on the market include pulsator washing and drum washing. The above washing methods can wash clothes cleanly, but the washing methods are single and traditional, without specificity. Moreover, it is impossible to adopt a reasonable and suitable cleaning method for underwear of different thicknesses, resulting in incomplete cleaning of the underwear and easy deformation of the underwear.

[0003] For example, Chinese invention patent publication number CN107700141A discloses an underwear washing machine, which includes a housing, an upper cover, a washing chamber, a water collecting chamber, and a base.

[0062] The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the present application and, together with the general description of the present application given above and the detailed description of the embodiments given below, serve to explain the principles of the present application.

[0063] These and other characteristics of the present application will become apparent from the following description of a preferred form of embodiment given as a non-limiting example with reference to the accompanying drawings.

[0064] It should also be understood that although the present application has been described with reference to certain specific examples, those skilled in the art will readily be able to implement many other equivalent forms of the present application.

[0065] The above and other aspects, features and advantages of the present application will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

[0066] Specific embodiments of the present application will be described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments described are merely examples of the present application and may be implemented in a variety of ways. Familiar and / or repetitive functions and structures are not described in detail to avoid obscuring the present application with unnecessary or redundant details. Therefore, the specific structural and functional details described herein are not intended to be limiting, but rather serve merely as a basis and representative basis for the claims to teach those skilled in the art to variously utilize the present application with substantially any suitable detailed structure.

[0067] This specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which may all refer to one or more of the same or different embodiments according to the present application.

[0068] To address the issues raised in the background technology, the present application provides an underwear washing device, wherein the underwear described herein refers to a bra. A sponge is placed in the cup of a bra. To better clean the bra, especially the cup portion where the sponge is placed, it is necessary to focus on scrubbing the cup portion of the bra to better remove dirt from the sponge placed in the cup. However, bras are prone to deformation during scrubbing, which affects the effectiveness of the bra. Therefore, the underwear scrubbing brush head proposed in the present application can focus on scrubbing the cup portion of the bra while minimizing the deformation of the cup portion.

[0069] Combine Figure 1 and Figure 2 , the underwear washing equipment includes:

[0070] The upper housing 1 has a bottom opening.

[0071] The upper brush head mechanism 2 is disposed within the upper shell 1. Here, the upper brush head mechanism 2 being disposed within the upper shell 1 may mean that the upper brush head mechanism 2 is completely located within the upper shell 1, or may mean that part of the upper brush head is located within the upper shell 1. For example, a portion of the bottom of the upper brush head mechanism 2 may protrude from the upper shell 1 through the lower opening, and when the upper shell 1 and the lower shell 3 are assembled together, the bottom of the upper brush head mechanism 2 may extend into the lower shell 3.

[0072] The lower housing 3 has an upper opening at its top and is connected to the upper housing 1. Specifically, the lower opening of the upper housing 1 can be snapped onto the upper opening of the lower housing 3. The upper and lower housings 1 and 3 can be connected by, but are not limited to, a hinged connection. When the underwear to be cleaned is placed in the underwear cleaning device, the upper housing 1 can be flipped open relative to the lower housing 3. The lower housing 3 and the upper housing 1 can enclose a cleaning chamber, in which the underwear to be cleaned can be placed.

[0073] Lower brush head mechanism 4, combined Figure 3 、 Figure 4 and Figure 5 The lower brush head mechanism 4 is arranged in the lower shell body 3, and the shapes of the upper brush head mechanism 2 and the lower brush head mechanism 4 are respectively adapted to the shapes of the cups of the underwear, so that the upper brush head mechanism 2 and the lower brush head mechanism 4 can better fit the upper and lower surfaces of the cups, better clean the cup part of the underwear, improve the cleaning effect, and avoid deformation of the underwear during the cleaning process.

[0074] The brush head of the upper brush head mechanism 2 and the brush head of the lower brush head mechanism 4 can rotate relative to each other in forward and reverse directions to scrub the underwear, thereby scrubbing the underwear repeatedly and improving the cleaning effect of the underwear.

[0075] The first driving mechanism 8, combined Figure 2 and Figure 11 The first driving mechanism 8 is arranged in the upper shell 1. Specifically, the first driving mechanism 8 can be arranged on the inner top surface of the upper shell 1. The first driving mechanism 8 is connected to the upper brush head mechanism 2 and drives the upper brush head mechanism 2 to move left and right or back and forth relative to the lower brush head mechanism 4, so as to perform translational scrubbing on the underwear placed between the upper brush head mechanism 2 and the lower brush head mechanism 4. Figure 16 、 Figure 17 and Figure 18 , the upper brush head mechanism 2 can move to the left to a position away from the lower brush head mechanism 4, or can move to just above the lower brush head mechanism 4, or can move to the right to a position away from the lower brush head mechanism 4. For example, the upper shell 1 and the lower shell 3 are both rectangular shell-like structures, and the length direction of the upper shell 1 can be used as the left-right direction or the front-back direction of the washing device. Taking the length direction of the upper shell 1 as the left-right direction of the washing device as an example, the first driving mechanism 8 can drive the upper brush head mechanism 2 to move back and forth left and right. During the reciprocating movement of the upper brush head mechanism 2 left and right, the upper brush head mechanism 2 can perform translational scrubbing on the upper surface of the cup of the underwear.

[0076] The second driving mechanism 5, combined Figure 4 、 Figure 5 、 Figure 6 and Figure 7 , which is connected to the lower housing 3. The second drive mechanism 5 can drive the lower brush head mechanism 4 to rise and fall to adjust the vertical distance between the lower brush head mechanism 4 and the upper brush head mechanism 2, thereby adapting the distance to underwear of different thicknesses. When cleaning, the user can choose the corresponding normal gear according to their needs. If the underwear is of a relatively common material thickness and regular size, they can simply select the corresponding normal gear. If the underwear is of a more special size and thickness, different gears can be selected according to the thickness of the underwear. The machine automatically adjusts the distance between the upper brush head mechanism 2 and the lower brush head mechanism 4 according to the selected gear, making the cleaning of the underwear more targeted and ensuring better washing results.

[0077] The first drive mechanism 8 drives the upper brush head mechanism 2 to move back and forth left and right or back and forth, and simultaneously coordinates the reciprocating rotation of the upper brush head mechanism 2 relative to the lower brush head mechanism 4 to achieve a combined washing method of two scrubbing methods: translational scrubbing and rotational scrubbing, thereby improving the cleaning effect of the underwear. The second drive mechanism 5 drives the lower brush head mechanism 4 to move up and down to adjust the vertical spacing between the lower brush head mechanism 4 and the upper brush head mechanism 2, thereby adapting the spacing between the two to underwear of different thicknesses, ensuring the cleaning effect while minimizing deformation of the underwear during the cleaning process. The relative reciprocating forward and reverse rotation of the brush heads of the upper brush head mechanism 2 and the lower brush head mechanism 4 can achieve repeated scrubbing of the underwear, thereby improving the cleaning effect of the underwear.

[0078] In some embodiments, combined Figure 8 、 Figure 9 and Figure 10 The underwear washing device further includes an upper inner shell 101, which is disposed within the upper shell 1, and an upper brush head mechanism 2 disposed on the upper inner shell 101. The upper inner shell 101 is a rectangular parallelepiped structure with an open top. The size of the upper inner shell 101 is smaller than that of the upper shell 1. The upper inner shell 101 can move left and right or forward and backward within the upper shell 1. The range of movement of the upper inner shell 101 within the upper shell 1 satisfies the requirement that the upper brush head mechanism 2 and the lower brush head mechanism 4 move back and forth relative to each other to perform translational cleaning of the underwear.

[0079] The first drive mechanism 8 includes a first drive motor 801, a first eccentric wheel 802, a connecting piece 803 and a fixing pin 804. The first drive motor 801 is arranged on the upper shell 1, and the output shaft of the first drive motor 801 is connected to the first eccentric wheel 802. One end of the connecting piece 803 is eccentrically arranged on the first eccentric wheel 802 through the fixing pin 804, and the other end of the connecting piece 803 is movably connected to the fixing column 1011 of the upper inner shell 101. Specifically, the first drive motor 801 can be arranged on the upper shell 1 through a motor base, and the output shaft of the first drive motor 801 extends downward and extends into the upper inner shell 101 and is connected to the first eccentric wheel 802. When the first drive motor 801 drives the first eccentric wheel 802 to rotate, the first eccentric wheel 802 drives the connecting piece 803 eccentrically arranged on the first eccentric wheel 802 to rotate, while pushing the upper inner shell 101 and the upper brush head mechanism 2 on the upper inner shell 101 to move back and forth left and right or back and forth.

[0080] Of course, it is understandable that the first drive mechanism 5 may also adopt other structural forms. For example, as needed, a rotating motor may be connected to one end of a connecting rod, the other end of the connecting rod being connected to the upper brush head body 203, and the rotating motor may reciprocate forward and reverse to achieve reciprocating drive of the upper brush head body 203. This is merely an example and does not constitute a limitation on the scope of protection of the claims.

[0081] The first driving mechanism 8 can realize the reciprocating drive of the upper brush head mechanism 2 to move left and right or back and forth, so that the underwear washing device can not only perform rotational washing on the underwear, but also perform translational scrubbing on the underwear.

[0082] In some embodiments, the Figure 8 and Figure 9 The underwear washing device also includes a guide shaft 102, one end of which is arranged on the inner side wall of one side of the upper shell 1, and the other end of the guide shaft 102 passes through the upper inner shell 101 and is connected to the inner side wall of the other side of the upper shell 1, so as to move the upper inner shell 101 back and forth or back and forth. For example, the underwear washing device may include two parallel guide shafts 102, and through-holes are provided on two opposite shell walls near the top opening of the upper inner shell 101, and the guide shaft 102 passes through the upper inner shell 101 through the through-holes. The two ends of the guide shaft 102 are respectively fixed to the two opposite inner side walls of the upper shell 1. The surface of the guide shaft 102 may be provided with a coating to increase its surface smoothness.

[0083] The guide shaft 102 is used to guide the upper inner shell 101 to move left and right or back and forth, so that the upper inner shell 101 and the upper brush head mechanism 2 arranged on the upper inner shell 101 can move smoothly.

[0084] In some embodiments, combined Figure 8 The upper brush head mechanism 2 includes two upper brush head assemblies 201, and the two upper brush head assemblies 201 are arranged at the same height.

[0085] Combined with 13 and Figure 14 , the two upper brush head assemblies 201 each include an upper brush head body 203, a plurality of upper flexible scrubbing bodies 204 and a third driving mechanism 9. The upper brush head body 203 is located below the upper inner shell 101, and the lower surface of the upper brush head body 203 is convex upward. The plurality of upper flexible scrubbing bodies 204 are arranged on the lower surface of the upper brush head body 203. The surface formed by the plurality of upper flexible scrubbing bodies 204 is adapted to the outer shape of the upper surface of the cup of the underwear. Specifically, the upper flexible scrubbing body 204 can protrude or extend downward from the lower surface of the upper brush head body 203 and form the free end of the upper flexible scrubbing body 204. The surface formed by the free ends of the plurality of upper flexible scrubbing bodies 204 is adapted to the outer shape of the upper surface of the cup of the underwear, so that the upper surface of the underwear cup can be better fitted on the upper flexible scrubbing body 204, thereby ensuring the cleaning effect of the upper brush head mechanism 2 on the upper surface of the cup.

[0086] The third driving mechanism 9 is located in the upper inner shell 101, and the third driving mechanism 9 passes through the upper inner shell 101 and is connected to the upper brush head body 203. Alternatively, the upper brush head body 203 is set on the upper fixing plate 202, and the upper fixing plate 202 is located below the upper inner shell 101. The upper fixing plate 202 can be convex upward to form an upwardly protruding upper protrusion adapted to the upper brush head body 203, and the two upper brush head bodies 203 are respectively mounted on the two upper protrusions.

[0087] The third drive mechanism 9 passes through the upper inner shell 101 and is connected to the upper fixed plate 202. It drives the upper brush head body 203 and the multiple upper flexible scrubbing bodies 204 provided on the upper brush head body 203 to rotate back and forth to scrub the upper surface of the underwear cup with rotation. The rotation scrubbing can be performed simultaneously with the translation scrubbing to achieve a combination of multiple scrubbing methods for the underwear, thereby improving the cleaning effect of the underwear. Here, the translation scrubbing and rotation scrubbing can be combined to achieve a cleaning effect similar to hand washing, that is, ensuring the cleaning effect while reducing the impact on the deformation of the underwear. When the upper brush head mechanism 2 rotates, the lower brush head can provide good support for the underwear. Although the lower brush head mechanism 4 does not rotate and translate, the rotation and translation of the upper brush head mechanism 2, in conjunction with the lower brush head mechanism 4, can achieve a certain degree of squeezing of the underwear, so that the lower brush head mechanism 4 can still clean the lower surface of the cup.

[0088] The third drive structure drives the upper brush head body 203 and the upper flexible scrubbing body 204 to rotate back and forth, scrubbing the upper surface of the cup. The upwardly convex lower surface of the upper brush head body 203 and the upper flexible scrubbing body 204 form a surface that conforms to the shape of the upper surface of the cup, thereby improving the fit between the upper brush head mechanism 2 and the upper surface of the cup and ensuring a good cleaning effect.

[0089] In some embodiments, combined Figure 13 、 Figure 14 and Figure 15 The third driving mechanism 9 includes a fixed seat, a third driving motor 903, a small gear 904, a large gear 905, a second hinge 906, a camshaft 908, a connecting shaft 909, a first hinge 910 and a rotating shaft 911.

[0090] The fixing base is arranged on the upper inner shell 101, and the fixing base includes an upper fixing base 902 and a lower fixing base 901, and the upper fixing base 902 is arranged on the lower fixing base 901. The third drive motor 903 is arranged on the upper fixing base 902, and the pinion 904 is connected to the output shaft of the third drive motor 903, wherein the output shaft of the third drive motor 903 is arranged horizontally. The large gear 905 is engaged with the small gear 904 so that it can rotate synchronously with the small gear 904 when the small gear 904 rotates. The large gear 905 is arranged horizontally, and a second eccentric wheel 907 is provided on the upper surface of the large gear 905. The camshaft 908 is connected to the large gear 905 and the second eccentric wheel 907, and the large gear 905 can rotate around the camshaft 908. One end of the camshaft 908 can be set on the fixing base. The camshaft 908 is arranged vertically. One end of the second hinge 906 is mounted on the second eccentric 907. The other end of the second hinge 906 is hinged to one end of the first hinge 910 via a connecting shaft 909. The first hinge 910 is movably mounted on the upper fixed seat 902. The second eccentric 907 can rotate with the rotation of the large gear 905. When the second eccentric 907 rotates, it can push one end of the second hinge 906 to rotate with the second eccentric 907. At the same time, the second hinge 906 can push the first hinge 910 connected to it to swing. The other end of the first hinge 910 is hinged to one end of the rotating shaft 911. The other end of the rotating shaft 911 passes through the fixed seat and is connected to the upper brush head body 203. The reciprocating rotation of the brush head body is driven by the above-mentioned connecting rod mechanism.

[0091] In some embodiments, the Figure 4 、 Figure 5 、 Figure 6 and Figure 7 The second driving mechanism 5 includes a second driving motor 501, a screw 502 and a fixed block 503. The output shaft of the second driving motor 501 is connected to one end of the screw 502, and the other end of the screw 502 is connected to the fixed block 503 by a thread, and the fixed block 503 is connected to the lower brush head mechanism 4. The second driving motor 501 can be set on the bottom plate 301 of the lower shell 3, and the screw 502 is arranged vertically. When the second driving motor 501 drives the screw 502 to rotate, the screw 502 drives the fixed block 503 and the lower brush head mechanism 4 to rise and fall. The fixed block 503 is equivalent to a nut that cooperates with the screw 502. The thickness of the nut is relatively large, so that when the screw 502 rotates, it can drive the lower brush head mechanism 4 to have a sufficient lifting distance, thereby meeting the cleaning requirements of underwear with different thickness requirements.

[0092] The lower brush head mechanism 4 is driven to rise and fall by the driving motor 501 , the screw 502 and the fixing block 503 , so that the lower brush head can push the underwear placed on the lower brush head mechanism 4 to rise and fall smoothly.

[0093] In some embodiments, the lower brush head mechanism 4 includes a guide post 402, and a guide sleeve 302 is disposed within the lower housing 3. One end of the guide post 402 is connected to the lower brush head mechanism 4, and the other end of the guide post 402 extends downward and into the guide sleeve 302. When the lower brush head mechanism 4 is raised or lowered, the guide post 402 moves up and down within the guide sleeve 302 to guide the lower brush head mechanism 4. The cooperation between the guide post 402 and the guide sleeve 302 ensures smooth raising and lowering of the lower brush head mechanism 4, and also serves as a guide for the raising and lowering of the lower brush head mechanism 4.

[0094] Specifically, the lower brush head mechanism 4 may include two or more guide posts 402, each of which is parallel to each other and arranged vertically. One end of the guide sleeve 302 can be fixed to the bottom plate 301 of the lower shell 3, and the other end of the guide sleeve 302 extends upward. The guide sleeve 302 is arranged vertically, and the number of guide sleeves 302 corresponds to the number of guide posts 402. The lower shell 3 can be a rectangular shell, and the guide sleeves 302 can include four, which are respectively arranged at the four corners of the lower shell 3. The arrangement of the guide sleeves 302 does not affect the arrangement of other structural components in the lower shell 3.

[0095] In some embodiments, the second drive mechanism 5 is connected to a controller 7 of the underwear washing device. The underwear washing device can be configured with multiple wash positions, each corresponding to underwear of varying thicknesses. For example, the controller 7 can be designed as a PCB and placed within the lower housing 3. The controller 7 can be mounted on the bottom plate 301 of the lower housing 3. The user can select the appropriate wash position as needed. The wash position is connected to the controller 7, which generates corresponding control instructions based on the selected position and transmits the control instructions to the second drive mechanism 5.

[0096] Combine Figure 6 and Figure 7 After receiving the control command from the controller 7, the second drive mechanism 5 moves up / down a preset distance according to the control command. The controller 7 can be embedded with an electronic control program that sets a default lifting height based on the general thickness parameters of underwear. It can also set a default height value specifically for ultra-thick or ultra-thin underwear. Based on user needs, if the underwear is of normal thickness, the controller 7 can issue a control command adapted to the normal thickness; if the underwear is of a special size and thickness, different gears are selected according to the different thicknesses of the underwear. The controller 7 issues corresponding control commands to automatically adjust the distance between the upper and lower brush head mechanisms 4, making the cleaning of the underwear more targeted, ensuring better washing results while reducing the impact on the underwear's deformation.

[0097] In some embodiments, the lower brush head mechanism includes a lower fixing plate 403 and two lower brush heads, which are arranged at the same height on the lower fixing plate 403. When cleaning underwear, the two cups of the underwear can be placed on the two lower brush heads 401 respectively, and the two lower brush heads 401 respectively support the two cups.

[0098] The two lower brush heads 401 set at the same height can achieve the same height placement of the two cups of the underwear. When the second driving mechanism 5 drives the lower brush head mechanism 4 to rise to the set position, the two upper brush head assemblies 201 of the equal-height upper brush head mechanism 2 can cooperate with the two lower brush heads 401 to achieve equal-height support and fixation of the two cups, avoiding the deformation of the underwear caused by pulling due to the different heights of the two cups during the cleaning process.

[0099] The underwear is placed on the lower brush head mechanism 4, and the second driving mechanism 5 drives the lower brush head mechanism 4 to move upward until the upper surface of the underwear cup contacts the upper brush head assembly 201. Here, the upward movement distance of the lower brush head mechanism 4 can be adjusted according to the thickness of the underwear. Since there is a sponge inside the cup, the contact degree between the upper surface of the cup and the upper brush head assembly 201 can be adjusted as needed. Figure 6 and Figure 7 For example, the greater the distance the lower brush head mechanism 4 moves upward, the higher the degree of contact between the upper surface of the cup and the upper brush head assembly 201, that is, the greater the force with which the cup is supported by the upper brush head mechanism 2 and the lower brush head mechanism 4, and the sponge in the cup can be cleaned more thoroughly; similarly, the smaller the distance the lower brush head mechanism 4 moves upward, the lower the degree of contact between the upper surface of the cup and the upper brush head assembly 201, that is, the smaller the force with which the cup is supported by the upper brush head mechanism 2 and the lower brush head mechanism 4, and the more gently the sponge in the cup is cleaned.

[0100] The above-mentioned structural form of the upper brush head mechanism 2 and the lower brush head mechanism 4 enables the cup of the underwear to be flattened between the upper brush head mechanism 2 and the lower brush head mechanism 4 when the underwear is washed, thereby reducing deformation of the underwear during the washing process.

[0101] Both lower brush heads 401 include a lower brush head body 4011 and multiple lower flexible scrubbing bodies 4012. The upper surface of the lower brush head body 4011 protrudes upward, and the multiple lower flexible scrubbing bodies 4012 are arranged on the upper surface of the lower brush head body 4011. The multiple lower flexible scrubbing bodies 4012 are used to clean the lower surface of the cup of the underwear.

[0102] The multiple lower flexible scrubbing bodies 4012 may be, but are not limited to, particles protruding upward from the upper surface of the lower brush head body 4011, or columns, or bristles disposed on the upper surface of the lower brush head body 4011. The lower flexible scrubbing bodies 4012 are deformable; the particles may be spherical, the columns may be cylindrical or conical, and the bristles may be soft or hard plastic. When cleaning underwear, the particles, columns, or bristles directly contact the surface of the underwear, generating friction with the lower surface of the cup to scrub the lower surface of the cup.

[0103] Both upper brush head assemblies 201 include an upper brush head body 203 and multiple upper flexible scrubbing bodies 204. The lower surface of the upper brush head body 203 is convex upward, and the multiple upper flexible scrubbing bodies 204 are arranged on the lower surface of the upper brush head body 203. The multiple upper flexible scrubbing bodies 204 are used to clean the upper surface of the cup of the underwear.

[0104] Similarly, the multiple upper flexible scrubbing bodies 204 can be particles protruding downward from the lower surface of the upper brush head body 203, or columns, or bristles disposed on the lower surface of the upper brush head body 203. The upper flexible scrubbing bodies 204 are deformable, the particles can be spherical particles, the columns can be cylindrical or conical, etc., and the bristles can be soft or hard bristles made of plastic, etc. When cleaning underwear, the particles, columns, or bristles directly contact the surface of the underwear, generating friction with the upper surface of the cup, thereby scrubbing the upper surface of the cup.

[0105] By setting the lower brush head body 4011 and the upper brush head body 203 to a structural form that is adapted to the shape of the cup, during the cleaning process of the underwear, the upper brush head mechanism 2 and the lower brush head mechanism 4 can fit well with the upper and lower surfaces of the cup, ensuring the cleaning effect while reducing the deformation of the underwear.

[0106] The lower brush head mechanism is driven by the second driving mechanism 5 to move up and down, so that the lower brush head mechanism 4 can cooperate with the upper brush head mechanism 2 to achieve cleaning of underwear of different thicknesses.

[0107] The lower fixing plate 403 has two upwardly protruding lower protrusions 4031 adapted to the lower brush head body. The two lower brush head bodies are respectively installed on the two lower protrusions 4031. The multiple lower flexible scrubbing bodies 4012 of the two lower brush heads are used to support the two cups of the underwear.

[0108] While the upper brush head mechanism is rotating and scrubbing the underwear, it can also perform translational scrubbing, so that upper scrubbing bodies of different lengths of the upper brush head mechanism can contact different positions on the upper surface of the cup, thereby improving the cleaning effect of the underwear. This cleaning effect is not a superposition of the cleaning effects of translational cleaning and rotational cleaning.

[0109] The underwear washing device further comprises a movable connecting member 6, which is deformable. The movable connecting member 6 can be made of a deformable material such as rubber.

[0110] The lower brush mechanism 4 is connected to the inner circumferential wall of the lower housing 3 via a movable connector 6. When the lower brush mechanism 4 moves upward or downward, the end of the movable connector 6 connected to the lower brush mechanism 4 moves upward or downward with the lower brush mechanism 4, while the end of the movable connector 6 connected to the inner circumferential wall of the lower housing 3 remains stationary. The movable connector 6 limits the maximum upward or downward movement of the lower brush mechanism 4. Specifically, when the movable connector 6 is deformed to its maximum upward position, the vertical spacing between the lower brush mechanism 4 and the upper brush mechanism 2 cannot be further reduced; when the movable connector 6 is deformed to its maximum downward position, the vertical spacing between the lower brush mechanism 4 and the upper brush mechanism 2 cannot be further reduced. Of course, the vertical movement distance of the lower brush mechanism 4 is achieved by the drive mechanism 5. For underwear of varying thicknesses, the movable connector 6 can achieve the minimum vertical spacing between the lower brush mechanism 4 and the upper brush mechanism 2 to accommodate the desired thickness without reaching maximum upward deformation. The deformable movable connecting member 6 can be deformed when the lower brush head mechanism 4 moves up and down, so that the lower brush head mechanism 4 can be stably arranged in the lower shell 3.

[0111] The movable connecting member 6 is annular, and the lower brush head mechanism 4 is connected to the inner circumference of the movable connecting member 6. The outer circumference of the movable connecting member 6 is connected to the inner circumferential wall of the lower shell 3 to separate the lower shell 3 into two parts, an upper and a lower part. Specifically, the annular movable connecting member 6 includes an inner ring body 601, an intermediate body and an outer ring body 602. The inner ring body 601, the intermediate body and the outer ring body 602 can be integrally formed, for example, made of a rubber material. The inner ring body 601, the intermediate body and the outer ring body 602 are arranged in sequence from the inside to the outside, and the inner ring body 601 can be folded and deformed upward and downward relative to the outer ring body 602. The inner circumference of the inner ring body 601 is connected to the lower brush head mechanism 4, and the outer circumference of the outer ring body 602 is connected to the inner circumferential wall of the lower shell 3.

[0112] The annular movable connecting piece 6 connects the lower brush head mechanism 4 to the inner wall of the lower shell 3, realizing the upper and lower separation of the lower shell 3, preventing water in the upper half of the lower shell 3 from entering the lower half of the lower shell 3 and affecting the structure installed in the lower half of the lower shell 3.

[0113] In some embodiments, combined Figure 2 and Figure 12The underwear washing device also includes a drying component 10, which is arranged on the upper shell 1, and the air outlet of the drying component 10 is connected to the washing chamber. The drying component 10 is used to dry the underwear placed on the lower brush head mechanism 4 after the underwear is washed. The drying component 10 includes a fan 1001, an air duct 1002 and a heating element 1003. The air duct 1002 is respectively arranged on the upper shell 1, the fan 1001 is arranged on the air duct 1002, and the heating element 1003 is arranged near the air inlet of the air duct 1002, and the air inlet of the air duct 1002 is connected to the outside. The air outlet of the air duct 1002 is connected to the washing chamber. When the fan 1001 rotates, it can blow the air heated by the heating element 1003 into the washing chamber through the air outlet of the air duct 1002 to dry the underwear placed on the lower brush head mechanism 4.

[0114] The drying assembly 10 can dry the underwear placed on the lower brush head mechanism 4, avoiding deformation of the underwear during drying. Moreover, when the underwear is in a drying state, the clothes are lifted up, and the underwear is dried more efficiently and more dryly.

[0115] The above describes in detail several embodiments of the present invention, but the present invention is not limited to these specific embodiments. Those skilled in the art can make various variations and modifications based on the concept of the present invention, and these variations and modifications should fall within the scope of protection claimed by the present invention.
