Description

Technical Field

[0001] The utility model relates to the technical field of underwear cleaning equipment, in particular to underwear cleaning equipment. Background Art

[0002] The main types of washing machines currently on the market include pulsator washing and drum washing. The above washing methods can wash clothes clean, but the washing methods are relatively traditional and not targeted. 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, and cannot adjust the position of the washing structure according to the thickness of the underwear. Utility Model Content

[0004] The purpose of the embodiments of the present utility model is to provide an underwear cleaning device to solve the problem in the prior art that the cleaning structure cannot be adjusted according to the thickness of the underwear to prevent the underwear from being deformed.

[0005] The embodiment of the present utility model adopts the following technical solution: an underwear cleaning device, comprising:

[0006] An upper shell having a bottom opening;

[0007] an upper brush head mechanism, which is disposed in the upper shell;

[0008] A lower shell having an upper opening on its top, the lower shell being connected to the upper shell, and the lower shell and the upper shell enclosing each other to form a cleaning chamber;

[0009] a lower brush head mechanism disposed within the lower housing, wherein the shapes of the upper brush head mechanism and the lower brush head mechanism are respectively adapted to the shapes of the cups of the underwear, and the brush heads of the upper brush head mechanism and the lower brush head mechanism are capable of relatively reciprocating forward and reverse rotations to scrub the underwear;

[0010] A driving mechanism is arranged in the lower shell body, and the driving mechanism can drive the lower brush head mechanism to rise and fall, so as to adjust the vertical distance between the lower brush head mechanism and the upper brush head mechanism, thereby making the distance adapt to underwear of different thicknesses.

[0011] The lower brush head mechanism is driven by a driving mechanism to move up and down to adjust the vertical spacing between the lower and upper brush head mechanisms, thereby adapting the spacing between the two to accommodate underwear of varying thicknesses, thereby ensuring a cleaning effect while minimizing deformation of the underwear during the cleaning process. The brush heads of the upper and lower brush head mechanisms can be rotated back and forth relative to each other in forward and reverse directions to achieve repeated scrubbing of the underwear, thereby improving the cleaning effect.

[0012] In some embodiments, the lower brush head mechanism includes two lower brush heads, and the two lower brush heads are arranged at the same height;

[0013] The upper brush head mechanism includes two upper brush head assemblies, and the two upper brush head assemblies are arranged at the same height;

[0014] The underwear is placed on the lower brush head mechanism, and the driving mechanism drives the lower brush head mechanism to move upward until the upper surface of the cup of the underwear contacts the upper brush head assembly.

[0015] The above-mentioned structural form of the upper brush head mechanism and the lower brush head mechanism enables the cup of the underwear to be flattened between the upper brush head mechanism and the lower brush head mechanism when the underwear is washed, thereby reducing deformation of the underwear during the washing process.

[0016] In some embodiments, the driving mechanism includes a driving motor, a screw and a fixed block. The output shaft of the driving motor is connected to one end of the screw, and the other end of the screw is connected to the fixed block through a thread. The fixed block is connected to the lower brush head mechanism. When the driving motor drives the screw to rotate, the screw drives the fixed block and the lower brush head mechanism to rise and fall.

[0017] The lower brush head mechanism is driven to rise and fall by the cooperation of the driving motor, the screw rod and the fixing block, so that the lower brush head can push the underwear placed on the lower brush head mechanism to rise and fall smoothly.

[0018] In some embodiments, the underwear washing device further comprises a movable connecting member, and the movable connecting member is capable of deformation;

[0019] The lower brush head mechanism is connected to the inner peripheral wall of the lower shell through the movable connecting piece. When the lower brush head mechanism moves upward / downward, the end of the movable connecting piece connected to the lower brush head mechanism moves upward / downward along with the lower brush head mechanism.

[0020] The deformable movable connecting piece can be deformed when the lower brush head mechanism moves up and down, so that the lower brush head mechanism can be stably arranged in the lower shell.

[0021] In some embodiments, the movable connecting member is annular, the lower brush head mechanism is connected to the inner circumference of the movable connecting member, and the outer circumference of the movable connecting member is connected to the inner circumference of the lower shell to separate the lower shell into two parts.

[0022] The annular movable connecting piece connects the lower brush head mechanism to the inner wall of the lower shell, realizing the upper and lower separation of the lower shell, preventing water in the upper half of the lower shell from entering the lower half of the lower shell and affecting the structure installed in the lower half of the lower shell.

[0023] In some embodiments, the lower brush head mechanism includes a guide column, and a guide sleeve is provided in the lower shell body. One end of the guide column is connected to the lower brush head mechanism, and the other end of the guide column extends into the guide sleeve. When the lower brush head mechanism is raised or lowered, the guide column moves up and down in the guide sleeve to guide the raising and lowering of the lower brush head mechanism.

[0024] The cooperation between the guide column and the guide sleeve realizes the smooth lifting and lowering of the lower brush head mechanism, and plays a guiding role in the lifting and lowering of the lower brush head mechanism.

[0025] In some embodiments, the driving mechanism is connected to a controller of the underwear washing device. After receiving a control instruction sent by the controller, the driving mechanism moves up / down a preset distance according to the control instruction.

[0026] The controller can be implanted with an electronic control program, which sets the default lifting height according to the general thickness parameters of the underwear. It can also set default height values ​​for ultra-thick or ultra-thin underwear in a targeted manner. According to user needs, if it is underwear of ordinary thickness, the controller can issue control instructions adapted to underwear of ordinary thickness; if it is underwear of special size and thickness, different gears are selected according to underwear of different thicknesses, and the controller issues corresponding control instructions to automatically adjust the distance between the upper and lower brush head mechanisms, which is more targeted for cleaning underwear, so as to ensure better washing effects while reducing the impact on the deformation of the underwear.

[0027] In some embodiments, both of the lower brush heads include a lower brush head body and a plurality of lower flexible scrubbing bodies, the upper surface of the lower brush head body protrudes upward, and the plurality of lower flexible scrubbing bodies are arranged on the upper surface of the lower brush head body, and the plurality of lower flexible scrubbing bodies are used to clean the lower surface of the cup of the underwear.

[0028] By setting the lower brush head body to a structural form that is adapted to the shape of the cup, the underwear can be well supported. During the cleaning process of the underwear, the lower brush head mechanism is well fitted with the lower surface of the cup, ensuring the cleaning effect while reducing the deformation of the underwear.

[0029] In some embodiments, both of the upper brush head assemblies include an upper brush head body and a plurality of upper flexible scrubbing bodies, the lower surface of the upper brush head body is convex upward, and the plurality of upper flexible scrubbing bodies are arranged on the lower surface of the upper brush head body, and the plurality of upper flexible scrubbing bodies are used to clean the upper surface of the cup of the underwear.

[0030] By setting the upper brush head body 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 is well fitted with the upper surface of the cup, ensuring the cleaning effect while reducing the deformation of the underwear.

[0031] In some embodiments, the lower brush head mechanism further comprises a lower fixing plate having two upwardly protruding lower protrusions adapted to the lower brush head body, the two lower brush head bodies being respectively mounted on the two lower protrusions, and the multiple lower flexible scrubbing bodies of the two lower brush heads being used to support the two cups of the underwear;

[0032] The lower fixing plate is connected to the driving mechanism to drive the two lower brush heads and the underwear to rise and fall synchronously.

[0033] The two brush heads of the lower brush head mechanism respectively support the two cups of the underwear and can simultaneously achieve the lifting and lowering of the two cups.

[0034] The beneficial effects of the embodiments of the present utility model are:

[0035] The lower brush head mechanism is driven to move up and down by a driving mechanism to adjust the vertical distance between the lower brush head mechanism and the upper brush head mechanism, so that the distance between the two can adapt to underwear of different thicknesses, ensuring the cleaning effect while avoiding deformation of the underwear during the cleaning process as much as possible.

[0046] Various aspects and features of the present application are described herein with reference to the accompanying drawings.

[0047] It should be understood that various modifications may be made to the embodiments of the present application. Therefore, the above description should not be considered as limiting, but merely as an example of an embodiment. Other modifications within the scope and spirit of the present application will occur to those skilled in the art.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] The embodiments of the present application provide an underwear cleaning 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 where the sponge is placed, it is necessary to focus on scrubbing the cup to better remove dirt from the sponge. However, bras are prone to deformation during scrubbing, which affects the effectiveness of the bra. Therefore, the underwear scrubbing brush head proposed in this application can focus on scrubbing the cup of a bra while minimizing the deformation of the cup.

[0055] Combine Figure 1 and Figure 2 , the underwear cleaning device includes:

[0056] The upper housing 1 has a bottom opening.

[0057] 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.

[0058] 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.

[0059] The lower brush head mechanism 4 is arranged in the lower shell body 3. 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 with 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.

[0060] 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.

[0061] The drive mechanism 5 is connected to the lower housing 3 and is capable of driving the lower brush head mechanism 4 to rise and fall, thereby adjusting the vertical spacing between the lower brush head mechanism 4 and the upper brush head mechanism 2, thereby adapting the spacing to underwear of different thicknesses. When cleaning, the user can select the corresponding normal gear according to their needs. If the underwear is of a relatively common material thickness and regular size, the corresponding normal gear can be simply selected. If the underwear is of a more special size and thickness, a different gear 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.

[0062] In the embodiment of the present application, the driving mechanism 5 drives the lower brush head mechanism 4 to move up and down to adjust the vertical distance between the lower brush head mechanism 4 and the upper brush head mechanism 2, so that the distance between the two is adapted to underwear of different thicknesses, ensuring the cleaning effect while avoiding deformation of the underwear during the cleaning process as much as possible.

[0063] In some embodiments, combined Figure 3 、 Figure 4 and Figure 5 The lower brush head mechanism 4 includes two lower brush heads 401, and the two lower brush heads 401 are arranged at the same height. When the underwear needs to be cleaned, 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.

[0064] 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.

[0065] 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 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 upper brush head mechanism 2 can cooperate with the two lower brush heads 401 to achieve the same 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.

[0066] The underwear is placed on the lower brush head mechanism 4, and the 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 7 and Figure 8 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.

[0067] 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.

[0068] In some embodiments, combined Figure 2 and Figure 4 The driving mechanism 5 includes a driving motor 501, a screw 502 and a fixed block 503. The output shaft of the 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 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 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.

[0069] 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.

[0070] Of course, it is understandable that the driving mechanism 5 can also adopt other driving mechanisms to drive the lower brush head mechanism 4.

[0071] In some embodiments, combined Figure 4 、 Figure 5 、 Figure 7 and Figure 8 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.

[0072] 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.

[0073] In some embodiments, as Figure 5 As shown, 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.

[0074] 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.

[0075] In some embodiments, as Figure 4 As shown, 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.

[0076] 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.

[0077] In some embodiments, as Figure 2 As shown, the drive mechanism 5 is connected to the controller 7 of the underwear washing device. The underwear washing device can be configured with multiple washing positions, each corresponding to underwear of different 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 washing position as needed. The washing position is connected to the controller 7, which generates corresponding control instructions based on the selected position and sends the control instructions to the drive mechanism 5.

[0078] After receiving control commands from the controller 7, the drive mechanism 5 moves up / down a preset distance in response to the control commands. 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 specifically set default height values ​​for extra-thick or extra-thin underwear. Based on user needs, if the underwear is of normal thickness, the controller 7 can issue control commands adapted to normal thickness. For underwear of a special size or thickness, different gears are selected based on the thickness of the underwear. The controller 7 issues corresponding control commands, automatically adjusting the distance between the upper and lower brush head mechanisms 4, providing more targeted cleaning of the underwear, ensuring better washing results while minimizing the impact on underwear deformation.

[0079] In some embodiments, the Figure 2 、 Figure 3 and Figure 5The two lower brush heads 401 each include a lower brush head body 4011 and a plurality of lower flexible scrubbing bodies 4012. The upper surface of the lower brush head body 4011 protrudes upward, and the plurality of lower flexible scrubbing bodies 4012 are arranged on the upper surface of the lower brush head body 4011. The plurality of lower flexible scrubbing bodies 4012 are used to clean the lower surface of the cup of the underwear.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] The upper brush head mechanism 2 can also be connected to the rotation drive mechanism, which can drive the upper brush head body 203 of the upper brush head and the multiple upper flexible scrubbing bodies 204 arranged on the upper brush head body 203 to rotate back and forth, so as to cooperate with the lower brush head mechanism 4 to achieve focused scrubbing of the cup part of the underwear.

[0085] The rotation drive mechanism can be in many forms. For example, by connecting a rotating motor to one end of a connecting rod, and connecting the other end of the connecting rod to the upper brush head body 203, the rotating motor can reciprocate forward and reverse to achieve reciprocating drive of the upper brush head body 203.

[0086] like Figure 6 As shown, the upper brush head mechanism 2 may further include an upper fixing plate 202, on which two upper protrusions protruding downward are provided, and two upper brush head bodies 203 are respectively provided on the two upper protrusions. A connecting rod may pass through the upper fixing plate 202 and be connected to the upper brush head bodies 203.

[0087] Of course, it is understandable that the rotation drive mechanism can also have other structural forms, as long as it can drive the upper brush head body 203 to rotate back and forth. This is only used as an example and does not constitute a limitation on the scope of protection of the claims.

[0088] In some embodiments, combined Figure 3 and Figure 5 The lower brush head mechanism 4 also includes a lower fixing plate 403, which has two upwardly protruding lower protrusions 4031 respectively adapted to the lower brush head body 4011. The lower fixing plate 403 can be made in an integral molding manner or by stamping.

[0089] The lower surfaces of the two lower brush head bodies 4011 are respectively fitted to the upper surfaces of the two lower raised portions 4031. The lower raised portions 4031 have a smooth curved surface that matches the lower surface of the lower brush head body 4011. The two lower brush head bodies 4011 can be fixed to the two lower raised portions 4031 respectively. For example, the lower brush head body 4011 can be fixed to the lower raised portions 4031 by gluing, or the lower brush head body 4011 can be detachably fixed to the lower raised portions 4031 by connecting members such as screws. The multiple lower flexible scrubbing bodies 4012 of the two lower brush heads are used to support the two cups of underwear. The upper ends of the multiple lower flexible scrubbing bodies 4012 enclose a curved surface that matches the lower surface shape of the cups, so that the lower surface of the cups can be highly fitted to the lower surface of the cups, thereby improving the cleaning effect of the underwear.

[0090] The lower fixing plate 403 is connected to the driving mechanism 5 to drive the two lower brush heads and the underwear to rise and fall synchronously. Specifically, the middle part of the bottom surface of the lower fixing plate 403 can be connected to the driving mechanism 5 to make the lower fixing plate 403 more stable when rising and falling.

[0091] The lower brush head mechanism 4 also includes a lower fixing plate 403, on which two lower brush heads are mounted, each used to support the two bra cups. The lower fixing plate 403 is connected to the drive mechanism 5 to drive the two lower brush heads and the underwear placed on them to rise and fall synchronously.

[0092] After the underwear is cleaned, the lower brush head mechanism 4 supports the underwear, so that the underwear can maintain its original shape during drying.

[0093] The two brush heads of the lower brush head mechanism 4 respectively support the two cups of the underwear and can synchronously realize the lifting and lowering of the two cups, so that when the underwear needs to be cleaned, the underwear can be pushed smoothly to the upper brush head mechanism 2; or after the underwear is cleaned, the underwear can be moved downward smoothly so that the underwear is separated from the upper brush head mechanism 2.

[0094] 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.
