[0086] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention as detailed in the appended claims.

[0087] Existing washing machines lack targeted cleaning capabilities for underwear and other intimate apparel, making them ineffective. The bra squeezing and washing mechanism in an embodiment of the present invention comprises a washing rack and a cam transmission structure. The washing rack has a third protrusion structure that mates with the bra cups. When a bra needs to be washed, the cam transmission structure drives the washing rack back and forth, squeezing and washing the bra cups via the two third protrusions on the washing rack. This achieves targeted washing of the bra and improves the cleaning effect.

[0088] M230040CNI-ZLSQ20230362

[0089] The following is combined with Figure 1-7 The technical solution of this embodiment is described in detail. The following implementation methods and embodiments can be combined with each other unless there is any conflict.

[0090] Example

[0091] like Figures 1-4 As shown, this embodiment provides a bra squeezing and washing mechanism, which includes a squeezing and washing device, wherein the squeezing and washing device includes:

[0092] The washing rack 5 has two third protruding structures 52 adapted to the bra cups, and the two third protruding structures 52 form two extrusion ends;

[0093] The cam transmission structure 6 includes a first cam 61 and a second cam 62 that cooperate with each other, and the axes of the first cam 61 and the second cam 62 coincide with each other. The first cam 61 has a first mating surface that cooperates with the second cam 62 and a connecting surface that connects with the washing rack 5. The second cam 62 has a second mating surface that cooperates with the first cam 62;

[0094] The second cam 62 can be driven to rotate. When the second cam 62 is driven to rotate, the second mating surface of the second cam 62 rotates and cooperates with the first mating surface of the first cam 61 to make the first cam 61 reciprocate along the axis. When the first cam reciprocates, it drives the washing rack 5 connected to it to reciprocate along the axis.

[0095] The bra squeezing and washing mechanism in the embodiment of the present invention is provided with a washing rack 5 and a cam transmission structure 6, wherein the washing rack 5 has two third protrusion structures 52 adapted to the bra cups. When the bra needs to be washed, the washing rack 5 can be driven to move back and forth by driving the cam transmission structure 6, and the two third protrusion structures 52 on the washing rack 5 are squeezed and washed on the two cups of the bra, so as to achieve targeted washing of the bra and improve the washing effect of the bra.

[0096] In any of the above embodiments, Figure 3 As shown, the washing rack 5 includes a main body 51 and two third protrusions 52 disposed on the main body 51. Both third protrusions 52 are hingedly connected to the main body 51 and connected by an elastic member. When the washing rack 5 is driven back and forth to squeeze bras, the two third protrusions 52 simultaneously rub along the surface of the bra cups, stretching and elastically deforming the elastic member between the two third protrusions 52. This means that when the washing rack 5 squeezes and washes bras, it not only achieves a squeezing washing effect but also a friction washing effect, resulting in a more effective washing process.

[0097] like Figure 4 As shown, the first mating surface of the first cam 61 is formed with a first convex-concave portion 611, and the second mating surface of the second cam 62 is formed with a second convex-concave portion 621. The first convex-concave portion 611 and the second convex-concave portion 621 can be rotatably matched;

[0098] M230040CNI-ZLSQ20230362

[0099] The first convex-concave portion 611 and the second convex-concave portion 621 have a first matching state and a second matching state that match each other;

[0100] When the first convex-concave portion 611 and the second convex-concave portion 621 are in the first mating state, the convex surface of the first convex-concave portion 611 is mated with the convex surface of the second convex-concave portion 621, and the first cam 61 and the second cam 62 are away from each other;

[0101] When the first convex-concave portion 611 and the second convex-concave portion 621 are in the second mating state, the first convex-concave portion 611 and the second convex-concave portion 621 are mated with each other, and the first cam 61 and the second cam 62 are close to each other;

[0102] When the second cam 62 is driven to rotate, the first cam 61 and the second cam 62 can be continuously switched between the first engagement state and the second engagement state.

[0103] In the embodiment of the present invention, by providing a first convex-concave portion 611 on the first cam 61 and a second convex-concave portion 621 on the second cam 62, the second convex-concave portion 621 can drive the first cam 61 to reciprocate through the cooperation of the second convex-concave portion 621 and the first convex-concave portion 611 when the second cam 621 is driven, thereby driving the washing rack 5 to reciprocate, and then the bras can be continuously squeezed and washed.

[0104] In any of the above embodiments, Figure 4 The first convex-concave portion 611 is formed with a first convex surface and a first concave surface, and a first connecting surface is formed between the first convex surface and the first concave surface;

[0105] The second convex-concave portion is formed with a second convex surface and a second concave surface, and a second connecting surface is formed between the second convex surface and the second concave surface;

[0106] When the first convex-concave portion 611 and the second convex-concave portion 621 are in the first mating state, the first convex surface of the first convex-concave portion 611 abuts against the second convex surface of the second convex-concave portion 621;

[0107] When the first convex-concave portion 611 and the second convex-concave portion 621 are in the second mating state, the first convex surface of the first convex-concave portion 611 abuts against the first concave surface of the second convex-concave portion 621, and the first concave surface of the first convex-concave portion 611 abuts against the second convex surface of the second convex-concave portion 621.

[0108] When the first convex-concave portion 611 and the second convex-concave portion 621 are in the second mating state, the first connecting surface and the second connecting surface at least partially abut against each other, thereby improving the stability of the first cam 61 and the second cam 62 in this mating state and preventing shaking therebetween.

[0109] Furthermore, in order to improve the smoothness of the transmission of the first cam 61 and the second cam 62, in the embodiment of the present invention, the first convex surface on the first convex-concave portion smoothly transitions to the first concave surface through the first connecting surface, and the second convex surface on the second convex-concave portion smoothly transitions to the second concave surface through the second connecting surface.

[0110] M230040CNI-ZLSQ20230362

[0111] In any of the above embodiments, Figure 1 As shown, a guide post 622 is formed on the second mating surface of the second cam 62. The guide post 622 is arranged at the center of the second cam 62 and extends along the axis direction of the second cam 62.

[0112] The first cam 61 is slidably sleeved on the guide post 622 . When the second cam 62 is driven to rotate, the first cam 61 reciprocates along the guide post 622 .

[0113] In the embodiment of the present invention, by providing a guide column 622 on the second cam 62, the first cam 61 can reciprocate along the axis of the second cam 62 when rotating with the second cam 62, thereby improving the stability of the first cam 61 during the reciprocating motion, and further improving the squeezing and washing effect on the bra.

[0114] Further, such as Figure 2 As shown, in this embodiment, a limiting structure 623 is provided at the end of the guide post 622 away from the second mating surface, wherein the limiting structure 623 is configured to prevent the first cam 61 from falling off the guide post 622. Preferably, the limiting structure 623 is a bolt connected to the upper end of the second cam 62, and the second cam 62 is connected to the clutch shaft 71 via the bolt.

[0115] Furthermore, a first through hole is provided on the first cam 61, and the first cam 61 is slidably sleeved on the outer periphery of the guide post 622 through the first through hole;

[0116] The washing rack 5 is provided with a second through hole, and the washing rack 5 is slidably sleeved on the outer periphery of the guide column 622 through the second through hole;

[0117] When the first cam 61 and the second cam 62 are in the first engagement state, the first cam 61 abuts against the limiting structure 623 or the washing rack 5 abuts against the limiting structure 623. Thus, when the first cam 61 is driven upward by the second cam 62, it can be quickly limited, thereby allowing the first cam 61 to quickly move downward, thereby preventing the second cam 62 and the first cam 61 from slipping during rotational engagement, improving the stability of the second cam 62 and the first cam 61 during rotational engagement, and increasing the reciprocating frequency of the first cam 61, thereby increasing the reciprocating frequency of the washing rack 5, and further improving the squeezing and washing effect on the bras.

[0118] In any of the above embodiments, the bra squeezing and washing mechanism further comprises a fixing device, such as Figure 5 As shown, the fixing device includes:

[0119] A first fixing member 1 and a second fixing member 2, wherein a clamping space for limiting the position of the bra is formed between the first fixing member 1 and the second fixing member 2;

[0120] When the washing rack 5 is driven to reciprocate, the squeezing end thereof can exert squeezing and washing force on the bra sandwiched between the first fixing member 1 and the second fixing member 2 .

[0121] M230040CNI-ZLSQ20230362

[0122] When washing a bra, the first fixing member 1 and the second fixing member 2 can clamp and limit the bra, and the washing rack 5 can squeeze and wash the clamped and limited bra, thereby preventing the bra from being deformed during washing and effectively protecting the bra.

[0123] In any of the above embodiments, the first fixing member 1 has two first protruding structures 11 adapted to the shape of the bra cup;

[0124] The second fixing member 2 has two second protruding structures 21 adapted to the shape of the bra cup;

[0125] The second fixing member 2 is covered on the first fixing member 1, and the two first protruding structures 11 and the two second protruding structures 21 are arranged in a one-to-one correspondence and have the same protruding direction;

[0126] When washing a bra, the two first protrusions 11 are used to fit the inner contour of the bra cup to serve as a support for the bra, and the two second protrusions 21 are used to fit the outer contour of the bra cup to clamp and limit the bra placed on the first fixing member 1.

[0127] Specifically, in the embodiment of the present invention, by arranging the first and second fixing members 1 and 2 according to the shape of the bra, the first and second fixing members 1 and 2 can effectively fit the front and back of the bra when washing, thereby improving the bra's securement while further reducing deformation during washing. Furthermore, because the bra is placed between the first and second fixing members 1 and 2 during washing, the washing rack 5 does not directly impact the bra's surface during washing, thereby effectively protecting the bra and reducing wear and tear on the bra.

[0128] In any of the above embodiments, Figure 5 As shown, the main contours of the first fixing member 1 and the second fixing member 2 are both arc-shaped components; it is worth noting that the arc in this embodiment is not an arc in the full sense, and the shape in some subtle places can also be other shapes that are different from the arc, as long as the overall shape is roughly arc-shaped.

[0129] The first protruding structure 11 is protruding from the main body contour of the first fixing member 1, and the first protruding structure 11 has a first outer convex surface;

[0130] The second protruding structure 21 is protruding from the main body contour of the second fixing member 2, and the second protruding structure 21 has a second inner convex surface;

[0131] The first outer convex surface of the first convex structure 11 is used to fit the inner contour surface of the bra cup, and the second inner convex surface of the second convex structure 21 is used to fit the outer contour surface of the bra cup.

[0132] In this embodiment, by configuring the first fixing member 1 and the second fixing member 2 to be arc-shaped, the bra can be placed between the first fixing member 1 and the second fixing member 2 to have a better fit.

[0133] M230040CNI-ZLSQ20230362

[0134] When washing a bra, the first outer convex surface of the first convex structure 11 is adapted to the inner contour surface of the bra, so that the inner contour surface of the bra is completely fitted on the first fixing component 1. The second inner convex surface of the second convex structure 21 is adapted to the outer contour surface of the bra, so that the second fixing component 2 can completely fit the outer contour surface of the bra when fixing the bra, and the first fixing component 1 can completely fit the inner contour surface of the bra, so as to achieve the effect of maximizing the squeezing coverage area of ​​the washing rack 5 during the washing process, thereby improving the fixing effect and washing effect of the bra and avoiding deformation of the bra.

[0135] like Figure 5 As shown in FIG, the two first protruding structures 11 are symmetrically arranged with the central axis of the first fixing member 1 as the symmetry center. The two second protruding structures 21 are symmetrically arranged with the central axis of the second fixing member 2 as the symmetry center.

[0136] In any of the above embodiments, the second fixing member is rotatably arranged, wherein the second fixing member 2 has a first state and a second state when rotating;

[0137] When the second fixing member 2 is in the first state, the second fixing member 2 clamps the limited bra;

[0138] When the second fixing member 2 is in the second state, the second fixing member 2 cancels the clamping limit on the bra, and the bra can be taken in and out.

[0139] In the embodiment of the present invention, the second fixing member 2 is rotatably arranged to facilitate the clamping and limiting of the bra, which is convenient for the user to operate and use.

[0140] In any of the above embodiments, a hollow structure is provided on the first fixing member 1 and / or the second fixing member 2, and when washing the bra, washing water can pass through the hollow structure and act on the bra. Preferably, a hollow structure is provided on both the first fixing member 1 and the second fixing member 2, and washing water can pass through the hollow structure and act on the outer contour surface and the inner contour surface of the bra.

[0141] When washing a bra, by providing a hollow structure on the first fixing member 1 and the second fixing member 2, washing water can pass through the hollow structure and act on the surface of the bra, thereby improving the cleaning ratio of the bra.

[0142] In any of the above embodiments, Figure 5 As shown, the fixing device further includes a bracket 3 whose position can be fixed, and the bracket 3 serves as a mounting carrier for the first fixing member 1;

[0143] When the first fixing member 1 is mounted on the bracket 3, the first fixing member 1 is closely fitted to the bracket 3. This improves the stability of the first contour frame 1 when mounted on the bracket 3, prevents the first fixing member 1 from shifting relative to the bracket 3 when washing bras, thereby preventing the bras from shifting during washing and improving the washing and fixing effects of the underwear.

[0144] M230040CNI-ZLSQ20230362

[0145] In any of the above embodiments, the bracket 3 is an arc-shaped structure. When the first fixing member 1 is placed in contact with the bracket 3, the outer arc surface of the bracket 3 is in contact with the inner arc surface of the first fixing member 1. By setting both the bracket 3 and the first fixing member 1 in an arc-shaped structure, the two can be easily connected.

[0146] In any of the above embodiments, the second fixing member 2 mentioned above is rotatably arranged on the first fixing member 1 or the bracket 3. By rotatably arranging the second fixing member 2 on the first fixing member 1 or the bracket 3, the bra can be conveniently taken in and out.

[0147] It should be noted that the second fixing member 2 in the embodiment of the present invention can be an integrated structure or a split structure. Figure 5 As shown, when the second fixing member 2 is an integrated structure, it is only necessary to hinge the left or right end of the second fixing member 2 to the first fixing member 1 or the bracket 3. Correspondingly, the right or left end of the second fixing member 2 is fixed to the first fixing member 1 and the bracket 3. When the second fixing member 2 is a split structure, it is necessary to hinge both the left and right ends of the second fixing member 2 to the first fixing member 1 or the bracket 3. At this time, the second fixing member 2 is composed of two separate arc-shaped frames on the left and right. When the second fixing member 2 needs to be closed, the two split contour frames are docked and fixed in the middle of the second fixing member 2. It should also be noted that when fixing the second fixing member 2, its fixing method can be any locking method with a locking effect, such as snap locking or bolt locking.

[0148] During the process of washing bras, the washing rack 5 squeezes the first fixing member 1 by moving up and down. Since the bracket 3 is arranged at the lower end of the first fixing member 1, when the washing rack 5 squeezes the first fixing member 1 by moving up and down, the bracket 3 will be squeezed first, which will affect the washing effect of the bras.

[0149] In order to improve the washing effect of the bra, the bracket 3 in this embodiment is provided with two clearance holes 31. When the first fixing member 1 is arranged on the bracket 3, the two clearance holes 31 are opposite to the two first inner convex surfaces of the two first protruding structures.

[0150] The two third protrusions 52 on the washing rack 5 are arranged in a one-to-one correspondence with the two clearance holes 31. When the washing rack 5 is driven to reciprocate, the two third protrusions 52 are driven to squeeze the first fixing member 1 and the bra sandwiched between the first fixing member 1 and the second fixing member 2.

[0151] When washing bras, the washing rack 5 can pass through the clearance hole 31 and act on the first fixing member 1, repeatedly squeezing the first fixing member 1 to achieve squeeze washing of the bras. The width of the clearance hole 31 is larger than the width of the washing rack 5, thereby preventing interference between the washing rack 5 and the support frame 3 during reciprocating motion. This improves the bra washing effect while enhancing the stability of the bra washing mechanism.

[0152] M230040CNI-ZLSQ20230362

[0153] It is worth noting that in this embodiment, the washing rack 5 at least partially passes through the clearance hole 31. This can be done either during reciprocating motion, or partially or entirely within the clearance hole 31. This is sufficient to ensure that the washing rack 5 can apply a washing force to the brassieres mounted on the first fixing member 1 during reciprocating motion without interfering with the clearance hole 31. However, it is relatively preferred that the extrusion end of the washing rack 5 be positioned so as to remain within the clearance hole 31. This results in a shorter reciprocating stroke, a higher reciprocating frequency, and a better extrusion washing effect.

[0154] In any of the above embodiments, in order to prevent the washing rack 5 from damaging the bras when squeezing and washing the bras, in this embodiment, part or all of the first fixing member 1 is designed to be flexible; and / or part or all of the washing rack 5 is designed to be flexible;

[0155] When part of the first fixing member 1 is designed to be flexible, the first protruding structure of the first fixing member 1 is designed to be flexible. When part of the washing rack 5 is designed to be flexible, the extrusion end of the washing rack 5 is designed to be flexible.

[0156] In any of the above embodiments, Figure 5 As shown, the bra squeezing and washing mechanism further includes a rotating structure, which includes a rotating portion having a cylindrical structure. The rotating portion is arranged around the outer periphery of the fixing device and is fixed to the fixing device in a linkage manner.

[0157] The rotating part can be driven to rotate and drive the fixing device to rotate synchronously.

[0158] In this embodiment, by providing a rotating portion that can be linked to the fixing device, the bra squeezing and washing mechanism can have multiple washing modes when in use. For example, when the rotating portion is linked to the fixing device, the rotating portion can drive the fixing device to rotate synchronously to perform a bra dehydration operation. When the rotating portion is not driven to rotate, the washing rack 5 can be driven to reciprocate to squeeze and wash the bras, thereby performing a bra washing operation.

[0159] In any of the above embodiments, Figure 5 As shown, the rotating portion includes a bottom wall and side walls disposed on the bottom wall. The side walls of the rotating portion are provided with protruding first ribs 42 and / or the bottom wall of the rotating portion is provided with protruding second ribs 411. The first ribs 42 and / or the second ribs 411 are arranged in an arc, strip, or wave shape. In this embodiment, the provision of ribs on the side walls and / or bottom wall of the rotating portion can enhance the water agitation effect during washing.

[0160] Specifically, such as Figure 5 As shown, the rotating part includes: a drain cylinder 4 formed by the bottom wall and side wall mentioned above, wherein the bottom of the drain cylinder 4 is constructed in a circular shape and the cylinder wall is constructed in an annular shape, one end of the annular cylinder wall is formed at the outer periphery of the cylinder bottom and the other end extends along the axial direction of the cylinder bottom; at least one drain hole is provided on the side wall of the drain cylinder 4, and at least one protruding

[0161] A rib 42 is provided around the outer periphery of the bracket 3 and is fixedly connected to the bracket 3. A laundry washing space is formed between the drain drum 4 provided around the outer periphery of the bracket 3 and the first and second fixing members 2 to achieve washing and dehydration of bras. At the same time, the formed laundry washing space can also prevent the bra straps from getting entangled with the first rib 42 on the drain drum 4.

[0162] More specifically, Figure 5 As shown, the rotating portion further includes a reinforcing plate 41, which is disposed at the bottom of the drain drum 4. The reinforcing plate 41 is provided with at least one protruding second rib 411. The reinforcing plate 41 at the bottom of the drain drum 4 improves the strength of the drain drum 4. The second rib 41 further enhances the stability of the drain drum 4 and creates a torrent flushing effect during washing.

[0163] In any of the above embodiments, Figure 1-Figure 5 As shown, the bra squeezing and washing mechanism further includes a driving device, which can selectively transmit power to the rotating part or to the cam transmission structure 6;

[0164] When the driving device selects to transmit power to the rotating part, the rotating part can be driven to rotate and drive the fixing device to rotate synchronously;

[0165] When the driving device selects to transmit power to the cam transmission structure 6 , the cam transmission structure can drive the washing rack to reciprocate to squeeze the bra sandwiched between the first fixing member 1 and the second fixing member 2 .

[0166] By enabling the driving device to selectively be connected to the cam transmission structure 6 for power or to be connected to the rotating part for power, the bra squeezing and washing mechanism can realize different washing modes. Specifically, when the driving device is selectively connected to the cam transmission structure 6 for power, the squeezing and washing mode is executed; when the driving device is selectively connected to the rotating part for power, the dehydration and washing mode is executed, thereby enabling the bra squeezing and washing device to have multiple washing modes.

[0167] Specifically, such as Figure 1-Figure 5 As shown, the driving device includes:

[0168] The clutch 7 and the clutch output shaft 71 provided at the output end of the clutch 7, the clutch output shaft 71 can be selectively connected to the cam transmission structure 6 or the rotating part through the clutch 7;

[0169] When the clutch output shaft 71 is connected to the cam transmission mechanism 6, the clutch output shaft 71 drives the second cam 62 in the cam transmission mechanism 6 to rotate, and the first cam 61 that cooperates with the second cam 62 drives the washing rack 5 to reciprocate, performing a squeezing and washing operation on the bras;

[0170] When the clutch output shaft 71 is connected to the rotating part, the clutch output shaft 71 drives the rotating part and the fixing device to rotate synchronously, performing a dehydration operation for bras or a spin washing operation for ordinary clothes.

[0171] On the other hand, Figure 6 and Figure 7 As shown, an embodiment of the present invention further provides a washing machine, which includes the bra washing mechanism mentioned above, wherein the washing machine includes a washing tub 8, and the bra washing mechanism is rotatably arranged in the washing tub 8.
