Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and in particular to a shoe washing machine. Background Technology

[0002] With the development of technology, smart technology is gradually moving from industry to daily life. Many household chores have been replaced by machines, such as washing machines, robot vacuums, dishwashers, and shoe washing machines. These home appliances have greatly freed up residents' hands and made home life easier and more comfortable. Among them, shoe washing machines are washing equipment specifically designed for the cleaning needs of shoes, which can automatically clean shoes.

[0003] Existing shoe washing machines generally fall into two categories: brush-type and spray-type. Brush-type shoe washing machines include impeller-type and cabinet-type machines. Impeller-type machines have an impeller inside the washing tub with brushes mounted on it. Shoes are freely placed in the tub, and the impeller drives the brushes to clean them. Cabinet-type machines have rotating brushes inside the washing chamber and shoe-holding devices near the brushes. During washing, the shoes are held in place near the brushes and cleaned by the rotating brushes. Spray-type shoe washing machines are similar to cabinet-type machines, but differ in that they have spray components located near the shoe-holding devices inside. During washing, these spray components spray water onto the shoes to rinse them.

[0004] Existing shoe washing machines have poor cleaning effects on shoes and cannot clean different areas of the shoes evenly. In addition, because the shoe cavity is relatively closed, existing shoe washing machines cannot effectively clean the inside of the shoes. Summary of the Invention

[0040] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0041] Example 1

[0042] Reference Figures 1-8 As shown, a shoe washing machine of the present invention includes,

[0043] Box 1;

[0044] The shoe upper cleaning mechanism 2 includes a base plate 21, a wheel frame 22, a brush plate 23, a rack 24, and a gear system 25. The base plate 21 is connected to the housing 1. The wheel frame 22 is slidably disposed on the base plate 21. The rack 24 is connected to the housing 1 parallel to the sliding direction of the wheel frame 22. The gear system 25 includes a connecting frame 251, which is connected to the wheel frame 22. The connecting frame 251 is rotatably disposed with a driving shaft 252, a first driven shaft 253, and a second driven shaft 254 that are parallel to each other. The driving shaft 252 is respectively provided with a first driving gear 255 and a second driving gear 256. The first driven shaft 253 is provided with a first driven gear 257 that meshes with the first driving gear 255. The second driven shaft 254 is provided with a second driven gear 258 that meshes with both the second driving gear 256 and the rack 24. The brush plate 23 is connected to the first driven shaft 253.

[0045] The shoe cleaning mechanism 3 is provided in multiple symmetrical sets. Each shoe cleaning mechanism 3 includes a turntable 31, a connecting rod assembly 32, and a guide 33. The turntable 31 is rotatably disposed in the housing 1. The connecting rod assembly 32 includes a first connecting rod 321 and a second connecting rod 322. One end of the first connecting rod 321 is rotatably connected to the turntable at an eccentric position at one end of the turntable, and the other end is hinged to one end of the second connecting rod 322. A brush head 34 is hinged to the other end of the second connecting rod 322. Multiple guides 33 are provided. All multiple guides 33 are connected to the housing 1, and each guide 33 is slidably connected to one of the second connecting rods 322.

[0046] The flipping mechanism 4 includes a cam assembly 41 of equal width, a cylindrical cam 42, and a shoe rack 43. The cam assembly 41 of equal width includes a cam 411 and a movable frame 412. The movable frame 412 is slidably disposed in the housing 1. The cam 411 is rotatably disposed in the movable frame 412. Multiple cylindrical cams 42 are provided and symmetrically connected to the inner wall of the housing 1. Multiple shoe racks 43 are provided and each corresponds to one cylindrical cam 42. One end of the shoe rack 43 is rotatably connected to the movable frame 412, and the other end is connected to a push rod 44, which is slidably connected to the groove 421 of the cylindrical cam 42.

[0047] Specifically, the housing 1 is rectangular in shape with an opening at the top. A base plate 21 spans the top of the housing 1 along its length. Two symmetrically arranged tracks extending along the length of the base plate 21 are provided on the base plate 21, and a through groove parallel to the tracks is provided between the two tracks. A rack 24 is connected to the housing 1 parallel to the base plate 21, and is located below the base plate 21. The wheel frame 22 includes a base plate, on the bottom surface of which two symmetrically arranged connecting seats are vertically connected. The ends of the two connecting seats opposite to the base plate are rotatably mounted. The rollers are mounted on a base plate, and a vertical rod is connected between two connecting seats. The two rollers roll along two slides, while the vertical rod passes through a through slot and extends vertically downward into the housing 1. The gear system 25 includes a connecting frame 251, which is connected to the bottom of the vertical rod. The drive shaft 252, the first driven shaft 253, and the second driven shaft 254 are all vertically rotatably connected to the connecting frame 251. The drive shaft 252 is located between the first driven shaft 253 and the second driven shaft 254. The drive shaft 252 is connected to the first driven shaft 253 and the second driven shaft 254 respectively. A first driving gear 255 and a second driving gear 256 are provided. A first driven gear 257 is coaxially mounted on a first driven shaft 253 and meshes with the first driving gear 255. A brush disk 23 is coaxially connected to the bottom of the first driven shaft 253. A second driven gear 258 is coaxially mounted on a second driven shaft 254 and meshes with both the rack 24 and the second driving gear 256. A base is connected to the bottom surface of the base plate 21. A first drive source is slidably mounted on the base, and the output shaft of the first drive source is coaxially connected to the driving shaft 252. It is conceivable that when the first drive source drives the driving shaft 252 to rotate, the first driving gear 255 and the second driving gear 256, which rotate with the driving shaft 252, respectively drive the first driven gear 257 and the second driven gear 258 that mesh with them to rotate, thereby causing the brush disk 23 connected to the first driven shaft 253 to rotate. At the same time, the rotating second driven gear 258 moves along the rack 24 that meshes with it, so that the brush disk 23 can move in the horizontal direction to clean different positions on the surface of the shoe.

[0048] Specifically, the shoe cleaning mechanism 3 can be set in one or more groups according to actual needs; for example, two groups can be symmetrically set to clean a pair of shoes. Each shoe cleaning mechanism 3 includes a turntable 31 driven by a second drive source and a connecting rod assembly 32. The connecting rod assembly 32 includes a first connecting rod 321 and a second connecting rod 322. One end of the first connecting rod 321 is rotatably connected to an eccentric position on any end face of the turntable 31, and the other end of the first connecting rod 321 is rotatably connected to one end of the second connecting rod 322. The other end of the second connecting rod 322 is rotatably connected to a brush head 34 for cleaning the inside of the shoe. The housing 1 is provided with multiple guide members 33 located on one side of each turntable 31. The guide members 33 are provided with guide grooves, and the second connecting rod 322 is slidably connected in the guide grooves. When the second drive source drives the turntable 31 to rotate, the connecting rod assembly 32 drives the brush head 34 connected to it to perform reciprocating extension and retraction actions (similar to the actions when manually cleaning the inside of the shoe), thereby cleaning the inside of the shoe.

[0049] Specifically, the flipping mechanism 4 is used to flip the shoes so that the brush 23 can wash different surfaces of the shoes. The flipping mechanism 4 includes a width-equal cam assembly 41, a cylindrical cam 42, and a shoe rack 43 for fixing the shoes. The width-equal cam assembly 41 and the cylindrical cam 42 are arranged opposite to each other in the housing 1. The width-equal cam assembly 41 includes a movable frame 412 that is horizontally slidably arranged in the housing 1 and a cam 411 that is rotatably arranged in the movable frame. The cam 411 is driven by a third drive source. There are multiple cylindrical cams 42 that correspond to the positions of the shoe rack 43. One end of the cylindrical cam 42 is connected to the inner wall of the housing 1. The shoe rack 43 is arranged between the width-equal cam assembly 41 and the cylindrical cam 42. One end of the shoe rack 43 is rotatably connected to the movable frame 412, and the other end is connected to a push rod 44. The end of the push rod 44 away from the shoe rack 43 is slidably connected to the groove of a corresponding cylindrical cam 42. When the third drive source drives the cam 411 to rotate, the movable frame 412 can drive the shoe rack 43 to move in the horizontal direction. The push rod 44 connected to the shoe rack 43 cooperates with the slide groove, so that the shoe rack 43 can flip during the process of moving the shoes forward, so that the brush plate 23 can brush the sides and bottom of the shoes. At the same time, the brush head 34 can be dislodged from the shoes to avoid the brush head 34 interfering with the shoes during the flipping process, ensuring the smooth progress of the shoe washing process.

[0050] Reference Figure 3 and Figure 4 As shown, further, it includes a first drive component 26, which includes a first drive source and a base. The base is connected to the substrate, the first drive source is slidably connected to the base, and the output end of the first drive source is connected to the drive shaft 252.

[0051] Furthermore, a groove parallel to the rack 24 is provided on the base, and the shape of the groove matches the shape of the first drive source. The first drive source is slidably disposed in the groove. Specifically, while driving the drive shaft 252 to rotate, the first drive source slides along the groove; the groove can support the first drive source and also limit the first drive source, making the brushing process of the brush plate 23 more stable.

[0052] Reference Figure 5 and Figure 6 As shown, further, a second drive assembly 35 is included. The second drive assembly 35 includes a second drive source, the output end of which is connected to a first rotating shaft. A driving bevel gear is connected to the end of the first rotating shaft away from the second drive source. A turntable 31 is coaxially mounted on a second rotating shaft, which is rotatably connected to the housing 1 via a bracket. A driven bevel gear meshing with the driving bevel gear is connected to the second rotating shaft. Specifically, the second drive source is mounted on a horizontal plate connected to the housing 1, and its output end is coaxially connected to a vertical first rotating shaft. It is conceivable that the bevel gear transmission structure can transmit large torques, making it suitable for heavy-load applications. Furthermore, due to the special properties of the bevel gear teeth, the entire drive mechanism can achieve angle changes, allowing the transmission shafts (i.e., the aforementioned first and second rotating shafts) to be on the same straight line, thus providing greater design flexibility. Simultaneously, bevel gear transmission has high transmission efficiency and stability.

[0053] This invention provides a selection of gear parameters, wherein the driving bevel gear is selected as follows: Figure 1 The gear parameters are as follows:

[0054]

[0055]

[0056] Driven gear selection such as Figure 2 The gear parameters are as follows:

[0057] Modulus mn 1 Number of teeth z 34 Tooth angle a 20 Tooth tip height coefficient h 1 helix angle B 0 Spiral direction Straight teeth Radial displacement coefficient xn 0 Common normal length w 11.63 Number of teeth across the test k 4.28 Accuracy level 5-HA GI Axial angle ∑ 90 Paired gears Drawing number Number of teeth 17 Gear ring radial runout tolerance Fr Cumulative tolerance of tooth pitch Fp 0.016 Tangential composite tolerance F'i 0.0206 Tooth pitch deviation Fpt 0.006

[0058] Furthermore, the guide member 33 is connected to the inner wall of the housing 1 via a fixed rod. The guide member 33 is provided with a guide groove that slopes towards the shoe rack, and the second connecting rod 322 is slidably connected to the guide groove. When the turntable 31 rotates, its angle... Where θ represents the rotation angle of the crank (i.e., the line connecting the center of turntable 31 to the hinge point between turntable 31 and the first connecting rod 321), ω represents the angular velocity of the crank, and t represents time. This represents the initial phase angle. In this mechanism, ω = 2π rad / s. Then θ = 2πt. Since one end of the first connecting rod 321 is connected to the eccentric position of the turntable 31, the rotation of the turntable 31 will cause the connecting rod assembly 32 to reciprocate in the horizontal direction. The position of the brush head 34 is: x = r cos(θ) + L2 cos(α) + L3 + d, where x represents the position of the guide 33, r represents the distance from the center of the turntable 31 to the hinge point between the turntable 31 and the first connecting rod 321, α represents the angle between the first connecting rod 321 and the horizontal direction, L2 represents the length of the first connecting rod 321, L3 represents the length of the second connecting rod 322, and d represents the length of the brush head 34. Therefore, x = 50cos(θ) + 100cos(α) + 240 + 95 (mm).

[0059] The velocity of brush head 34 is: v = -rωsin(θ) - L2αsin(α), where v represents the velocity of brush head 34 and α represents the angular acceleration of the second link 322; α = ω 2 r = (2π) 2 ×50=200π 2 .

[0060] Motion relationship: v = rωsin(θ) - L2αsin(α), that is, the velocity of brush head 34 is equal to the vector sum of the velocity of turntable 31 and the velocity of first link 321; therefore, v = -100πsin(θ) - 200π 2 sin(α)(m / s).

[0061] The acceleration of brush head 34: a = -rω 2 cos(θ)-L2α 2 cos(α), where a represents the acceleration of brush head 34, r represents the distance from the center of turntable 31 to the hinge point between turntable 31 and first link 321, L2 represents the length of first link 321, and a = -100π. 2 cos(θ) - 1.6 × 10 7 ×4π 4 cos(α)(m / s 2 ).

[0062] When the crank reaches its maximum eccentric position, the brush head 34 reaches its farthest position. At this point, the brush head 34 is at its maximum displacement point, also known as the apex or pole of the brush head 34. In this device, the farthest distance is the farthest range of motion of the brush head 34. As the shaft continues to rotate, the crank gradually returns to its original position, causing the brush head 34 to gradually return in the horizontal direction.

[0063] Furthermore, the system includes a third drive assembly 45, which comprises a third drive source connected to the housing 1, with its output end connected to a cam 411. The shoe washing machine of the present invention can control the rotation angle of the shoe rack 43 and the flip angle of the shoes by controlling the rotation angle of the cam 411.

[0064] Verification is as follows:

[0065] Because the pushing distance of cam 411 is S = R 凸轮 -R 凸轮 cosθ, the pushing distance S of cam 411 is equal to the travel distance S′ of push rod 44. Right now (Refer to Figure 16 Therefore, it can be seen that the angle through which the cam 411 rotates is in a one-to-one correspondence with the angle through which the push rod 44 rotates.

[0066] R 凸轮 The value is 85.52, and r is 5.52 (Note: When the cam 411's rotation angle is 0-30°, it is in the far-end stage; 30-90° is the range for discussion. When the cam 411's rotation angle is 30°, θ is 0°.)

[0067] The relevant parameters for cam 411 calculation are as follows:

[0068]

[0069]

[0070] Specifically, such as Figure 14 and Figure 15 As shown, cam 411 consists of six circular arcs. Composed of circles centered at O, O', and O', with O as the rotation reference axis, to achieve a thrust of 80mm, S max =Rr=80mm, and since the law of pushing distance is S=R-Rcosθ, and when θ=60° (cam 4 rotates through an angle of 90°), in order to ensure that OA is horizontal at this time, From the design outline, we can conclude that, taking the vertical position of OA as the starting position, the far-resting stage of the cam is... When cam 411 rotates 30°, the resting period ends and the push begins. When OA reaches the horizontal position, cam 411 pushes to half of its maximum push stroke; thereafter, it moves in a symmetrical motion pattern.

[0071] Furthermore, a support plate is connected to the inner wall of the housing 1, and the movable frame 412 is slidably mounted on the support plate. Specifically, a horizontally extending support plate is connected to the inner wall of the housing 1, the movable frame 412 is slidably mounted on the top of the support plate, a third drive source is connected to the bottom of the support plate, and the output shaft of the third drive source passes through the support plate and is connected to the cam 411 located inside the movable frame 412.

[0072] Furthermore, the first driving gear 255 and the second driven gear 258 are large-diameter gears, while the second driving gear 256 and the first driven gear 257 are small-diameter gears. Specifically, when the teeth of one gear mesh with the teeth of another gear, they rotate at a certain angular velocity; for the rack 24, when the teeth on the gear mesh with the teeth on the rack 24, they can transmit force through the friction between the tooth surfaces and the meshing geometry.

[0073] In gear transmissions, the transmission ratio can be achieved by changing the combination of gears. Different transmission ratios can be obtained by selecting gear combinations of different sizes.

[0074] The following are some gear parameters: the first driving gear 255 and the second driven gear 258 are as follows:

[0075]

[0076]

[0077] The gear parameters of the second driving gear 256 and the first driven gear 257 are as follows:

[0078] Modulus mn 1 Number of teeth z 20 Tooth angle a 20 Tooth tip height coefficient h 1 helix angle B 0 Spiral direction Straight teeth Radial displacement coefficient xn 0 Common normal length w 7.66 Number of teeth across the test k 3 Accuracy level 7-LF Gear pair center distance a 50 Paired gears Drawing number Number of teeth 80 Gear ring radial runout tolerance Fr 0.023 Total deviation of tooth profile Fɑ 0.01 Pitch accumulation tolerance FP 0.029 Tooth pitch limit deviation ±fpt ±0.01

[0079] Where N1 is the number of teeth on the large-diameter gear and N2 is the number of teeth on the small-diameter gear; the rack has 24 teeth, so N3 has 400 teeth, and the large-diameter gear has 80 teeth, therefore the transmission ratio is...

[0080] To adjust the speed of the gear transmission, the rotational speed of the drive shaft 252 can be changed, or the gear combination can be altered. In this mechanism, the rotational speed of the drive shaft 252 is the same as that of the first drive gear 255 and the second drive gear 256, therefore ω1 = ω4 = ω5, and...

[0081] In this mechanism, the rack 24 is fixed to convert rotational torque into linear motion, thereby driving the entire gear train's forward and backward movement. At this time, the second driven gear 258, meshing with the rack 24, rotates one revolution, and the brush disc 23 rotates [number of revolutions]. After the second driven gear 258 moves along the rack 24 for one cycle, the brush disk 23 rotates for the following number of revolutions:

[0082] Through the transmission and speed adjustment of the gear train 25, the brush disc 23 achieves a relatively high speed. This high-speed rotation allows for optimal cleaning of the shoe surface. Meanwhile, the gear and rack mechanism enables the brush disc to achieve a slower and smoother reciprocating motion. When the gear rotates via the rack 24, it transmits the torque from the drive shaft 252 to the two driven shafts. The speed and torque of the driven shafts relative to the drive shaft 252 can be adjusted according to the dimensions and transmission ratio of the gears and rack 24. Through the meshing transmission of the gear and rack, rotation is converted into forward motion, driving the gear train 25 mechanism forward, thereby achieving the reciprocating motion of the brush disc 23, enabling it to efficiently clean the shoe surface.

[0083] Reference Figure 4 As shown, furthermore, an elastic element 27 is connected between the wheel frame 22 and the connecting frame 251. Specifically, the elastic element 27 is a spring, which can provide some buffer space between the brush plate 23 and the shoe being washed, thereby ensuring that the brush plate 23 fits tightly with the shoe and improving the washing effect of the brush plate.

[0084] Reference Figure 7 As shown, the shoe rack 43 further includes a frame, with two opposite frame edges connected to a movable frame 412 and a push rod 44, respectively. Each of these two frame edges is connected to a locking block, which are arranged facing each other with their opposite surfaces being curved. Specifically, the frame is a rectangular frame, with a locking block on each of the two shorter frame edges, symmetrically arranged, and both locking blocks having curved surfaces on their opposite sides. When washing shoes, the two ends of the shoes are secured to the two locking blocks. Since the ends of the shoes are generally curved, they can fit snugly against the curved end faces of the locking blocks, providing good stability for the shoes.

[0085] Reference Figure 8 As shown, the cylindrical cam 42 further includes a main body, which is a cylindrical structure open at both ends, and a groove is provided on the inner wall of the main body. A typical cylindrical cam 42 has a cylindrical body with the groove on the outer side of the main body; however, the cylindrical cam 42 of this invention has a cylindrical structure open at both ends, with the groove located on the inner surface of the main body. It is conceivable that the cylindrical shape of the cylindrical cam 42 facilitates the connection between the push rod 44 and the cylindrical cam 42, reducing the overall size of the structure. Specifically, the push rod 44 is L-shaped, with one end connected to the shoe rack 43 and the other end slidably connected in the groove of the cylindrical cam 42. It is also conceivable that the equal-width cam assembly can avoid rigid impacts between mechanisms, making the entire structure operate smoothly and reliably with a longer service life.

[0086] Specifically, if the push stroke of the equal-width cam assembly 41 is 80mm, then the length of the cylindrical cam 42 is 80mm. Since it takes a 180° rotation angle to flip the upper to the sole, the spiral route of the groove is chosen to cover half of the side of the cylindrical cam 42. Considering that the push rod 44 may have a lot of contact surface in the cylindrical cam 42, which may cause excessive friction, one end of the push rod 44 is set to a hemispherical shape.

[0087] Specifically, the motion law of the equal-width cam assembly 41 is the same as that of the cylindrical cam 42. Let the radius of the cylindrical cam 42 be R, and the meanings of the other parameters are the same as in the previous table. When the rotation angle φ of the push rod 44 is 0, S = 0; when φ = φ... max S = S′ max The displacement formula for the constant width cam assembly 41 during its movement is: At this time, the pressure angles at various points of the cylindrical cam 42 are: The maximum pressure angle should then appear at Place, that is At this time, the maximum pressure angle of the cam mechanism is The maximum pressure angle α was calculated. max =9.87°, which is less than the commonly used allowable stress angle of 40°.

[0088] Example 2

[0089] Based on Embodiment 1, a spraying device and a drying device can be further installed in the housing 1. Together with the shoe upper cleaning mechanism, the shoe interior cleaning mechanism and the flipping mechanism, the shoe washing efficiency and quality of the entire shoe washing machine can be further improved, providing users with more convenience.

[0090] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
