For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0063] A mahjong tile cleaning method of this embodiment includes the following steps:

[0064] Step A, arranging the mahjong tiles neatly in a first state, and sequentially and orderly feeding the tiles from the tile inlet of the cleaning machine into the first cleaning area inside the cleaning machine;

[0065] Step B, driving the mahjong tiles to move in the first mahjong tile channel of the first cleaning area and pass through the cleaning channel of the first cleaning mechanism on the first mahjong tile channel, wherein the cleaning channel includes at least three wiping surfaces, and when the mahjong tiles pass through the cleaning channel, at least three surfaces are wiped and cleaned by the wiping surfaces;

[0066] Step C, driving the mahjong tiles from the first mahjong tile passage into the second mahjong tile passage of the second cleaning area, wherein the second state of the mahjong tiles in the second mahjong tile passage is perpendicular to the first state;

[0067] Step D, driving the mahjong tiles to move in a second mahjong tile channel in a second state, and pass through a cleaning channel of a second cleaning mechanism on the second mahjong tile channel, wherein the cleaning channel includes at least three wiping surfaces, and when the mahjong tiles pass through the cleaning channel, the remaining surfaces that are not wiped clean by the first cleaning mechanism are wiped clean by the wiping surfaces;

[0068] Step E, driving the mahjong tiles in the second mahjong tile channel to leave the cleaning machine from the tile outlet.

[0069] In this embodiment, when the mahjong tiles are moving in the first mahjong tile channel and the second mahjong tile channel, there are intervals between adjacent mahjong tiles, which can effectively prevent the mahjong tiles from gathering and piling up.

[0070] In this embodiment, the moving direction in the first mahjong tile passage in the first state is the width direction of the mahjong tile; the moving direction in the second mahjong tile passage in the second state is the length direction of the mahjong tile. Of course, as an equivalent, the moving direction in the first state can also be the length direction of the mahjong tile, and correspondingly, the moving direction in the second state can also be the width direction of the mahjong tile.

[0071] The present application is based on a mahjong tile cleaning machine of the first embodiment of the above-mentioned mahjong tile cleaning method. Figure 1 , Figure 2 As shown, the cleaning machine body 10 includes a card inlet 11 at the top of the cleaning machine body 10, and a card outlet 12 at one side of the cleaning machine body 10 near the bottom. Mahjong tiles 100 enter the cleaning machine body 10 from the card inlet 11 and leave the cleaning machine body 10 from the card outlet 12.

[0072] As a preferred embodiment, a card entry guide groove 30 is provided at the position of the card entry port 11 and is hinged to the cleaning machine body 10. The width of the card entry guide groove 30 is adapted to the length of the mahjong tiles 100. In this embodiment, the card entry guide groove 30 is used to facilitate the user to regularly feed the mahjong tiles from the card entry port 11 into the cleaning machine body 10. Since the card entry guide groove 30 is hinged, it is unfolded to the position where the mahjong tiles are cleaned. Figure 1 When not in use, folded to Figure 2 The state shown makes the mahjong tile cleaning machine occupy a smaller space and is convenient for storage; at the same time, the card inlet guide groove 30 covers the card inlet 11 in the folded state, which can effectively prevent debris from entering the interior of the cleaning machine body 10 through the card inlet 11.

[0073] In this embodiment, Figure 3 As shown, two mahjong tile cleaning areas are arranged horizontally side by side inside the cleaning machine body 10, namely, a first cleaning area connected to the card inlet 11 and a second cleaning area connected to the card outlet 12. In the first cleaning area, an arc-shaped first track 50 is provided, and a first mahjong tile channel for accommodating the mahjong tiles 100 is formed between the first track 50 and the outer shell of the cleaning machine body 10. Preferably, in this embodiment, the width of the first mahjong tile channel (i.e., the width of the first track 50) is adapted to the length of the mahjong tiles 100.

[0074] In this embodiment, an arc-shaped second track 60 is provided in the second cleaning area, and a second mahjong passage for accommodating mahjong tiles 100 is formed between the second track 60 and the housing of the cleaning machine body 10. The width of the second mahjong passage (i.e., the width of the second track 60) is adapted to the width of the mahjong tiles 100.

[0075] In this embodiment, Figure 1-3 As shown, in the mahjong tile cleaning machine of this embodiment, at least one cleaning mechanism 20 is provided in both the first cleaning area and the second cleaning area. Preferably, in this embodiment, a first cleaning mechanism 201 is provided on the first mahjong tile passage, and a second cleaning mechanism 202 is provided on the second mahjong tile passage.

[0076] The cleaning mechanism 20 of this embodiment is as follows Figure 12-18As shown, it includes a mechanism body 21 , one side of which is provided with a cleaning channel 24 for accommodating the passage of mahjong tiles, and a side of the mechanism body 21 away from the cleaning channel 24 is provided with a liquid replenishing chamber 211 .

[0077] In this embodiment, the cleaning channel 24 is provided with four wiping surfaces, namely, a first wiping surface 241 located on one side of the mechanism body 21, a second wiping surface 242 and a third wiping surface 243 extending from both ends of the first wiping surface 241 in a direction away from the mechanism body 21, and a fourth wiping surface 244 arranged opposite to the first wiping surface 241. A flexible wiping material 26 is provided on each wiping surface, and the specific material is not limited in this embodiment, and existing materials that can be used to wipe mahjong tiles can be selected, including but not limited to sponges.

[0078] In this embodiment, as a preference, a through groove 25 penetrating the fourth wiping surface along the extension direction of the cleaning channel is provided on the fourth wiping surface 244 . The provision of the through groove 25 facilitates driving the mahjong tiles through the cleaning channel 24 .

[0079] In this embodiment, Fig.17 As shown, a mounting groove 261 for mounting the wiping material 26 is provided on the surface of the cleaning channel 24, and a retaining edge 262 is provided on the side of the mounting groove 261 close to the through groove 25 and the rear side (the side where the mahjong tiles leave the cleaning channel). Of course, a retaining edge can also be provided on the front side of the mounting groove 261 (the side where the mahjong tiles enter the cleaning channel).

[0080] As a special feature of this embodiment, it also includes a liquid replenishing mechanism for replenishing the cleaning liquid. Figure 12-17 As shown, the refilling mechanism includes a liquid storage tank 221 disposed on a side of the mechanism body away from the cleaning channel, and the liquid storage tank 221 is provided with a sliding portion 222 slidably connected to the refilling chamber 211. A guide structure is provided between the sliding portion 222 and the inner wall of the refilling chamber 211. Preferably, in this embodiment, the guide structure includes a plurality of guide grooves 224 vertically disposed on the sliding portion 222 and a guide protrusion 213 disposed on the inner wall of the refilling chamber and slidably connected to the guide grooves 224. Preferably, guide structures are distributed between the opposite sides of the sliding portion 222 and the refilling chamber.

[0081] Furthermore, if Fig.15 , Fig.18 As shown, a limiting step 226 is provided at one end of the guide groove 224 close to the mechanism body, and the limiting step 226 and the guide protrusion 213 form a limiting mechanism to prevent the liquid storage tank from being separated from the liquid replenishing cavity.

[0082] In this embodiment, Fig.14 , Fig.16As shown, the liquid outlet 223 of the liquid storage tank 221 faces the bottom of the liquid replenishing chamber 211, and the liquid outlet 223 is provided with a one-way valve 27. It should be noted that the structure of the one-way valve is a prior art and is not described in detail here. In a natural state, the one-way valve 27 closes the liquid outlet 223. When the one-way valve 27 is pressed, the liquid outlet 223 is opened, and the cleaning liquid in the liquid storage tank can flow into the liquid replenishing chamber.

[0083] In this embodiment, Fig.17 As shown, the mechanism body 21 is provided with a plurality of liquid replenishing holes 214 connecting the liquid replenishing cavity 211 and the wiping material 26. The cleaning liquid in the liquid replenishing cavity flows to the wiping material through the liquid replenishing holes 214 and penetrates into the wiping material, thereby improving the cleaning effect of the mahjong tiles.

[0084] In this embodiment, Fig.17 As shown, a convex column 212 abutting against the one-way valve 27 is disposed at the bottom of the fluid infusion chamber 211 , and a plurality of protrusions 215 are disposed around the convex column 212 , and the plurality of protrusions 215 form a spring mounting portion of this embodiment.

[0085] In this embodiment, a boss 225 is provided on the side of the liquid storage tank 221 facing the liquid replenishing cavity, wherein the liquid outlet is provided on the boss 225. In addition, in this embodiment, an elastic member is provided between the liquid storage tank and the bottom of the liquid replenishing cavity. Preferably, the elastic member is a spring 28, one end of which is sleeved on the boss 225, and the other end is installed on the spring mounting portion.

[0086] The mahjong tile cleaning mechanism of this embodiment is as follows in the natural state: Figure 12-15 As shown, the liquid outlet is closed by a one-way valve. When the mahjong tiles pass through the cleaning channel, the outer surfaces of the mahjong tiles that contact the wiping surfaces are wiped clean by the wiping surfaces. Fig.16 In the state shown, the liquid outlet is opened, and the cleaning liquid in the liquid storage tank flows into the liquid replenishing cavity. The cleaning liquid in the liquid replenishing cavity penetrates from the liquid replenishing hole to the wiping material on the wiping surface, which can improve the cleaning effect. After the pressure is released, the liquid storage tank returns to the Figure 12-15 The liquid outlet is closed by the one-way valve.

[0087] In the present embodiment, in the first cleaning mechanism 201, the width of the cleaning channel 24 is adapted to the length of the mahjong tiles 100. When the mahjong tiles pass through the cleaning channel 24 of the first cleaning mechanism 201, the upper surface and lower surface formed by the length and width, and the two end surfaces formed by the width and height, a total of four surfaces are wiped clean. When the mahjong tiles pass through the second cleaning mechanism 202 in the second cleaning area, because the width of the cleaning channel of the second cleaning mechanism 202 is adapted to the width of the mahjong tiles, the upper surface and lower surface formed by the length and width of the mahjong tiles, and the two side surfaces formed by the length and height, a total of four surfaces are wiped clean. In this way, after the mahjong tiles pass through the first cleaning mechanism 201 and the second cleaning mechanism 202 in turn, the six surfaces are wiped clean, thereby achieving the purpose of thoroughly cleaning the surface of the mahjong tiles, and changing the cleaning method of the existing mahjong tile cleaning machine. Its advantage is that the mahjong tiles regularly pass through the first cleaning area and the second cleaning area in turn, and will not cause the mahjong tiles to accumulate and block.

[0088] It should be noted that, although in this embodiment, the cleaning channels 24 of the first cleaning mechanism 201 and the second cleaning mechanism 202 are both provided with four wiping surfaces. As a feasible implementation, the cleaning channel 24 of the first cleaning mechanism 201 can also be provided with three wiping surfaces, namely the second wiping surface 242, the third wiping surface 243 and the fourth wiping surface 244; correspondingly, the cleaning channel 24 of the second cleaning mechanism 202 is still provided with four wiping surfaces. With such an arrangement, after the mahjong tiles pass through the first cleaning mechanism 201 and the second cleaning mechanism 202 in sequence, it can still be ensured that the six surfaces are wiped clean, thereby achieving the purpose of thoroughly cleaning the surface of the mahjong tiles.

[0089] In addition, it should be noted that, in this embodiment, the width of the first mahjong tile passage is adapted to the length of the mahjong tile, and the width of the second mahjong tile passage is adapted to the width of the mahjong tile. As an equivalent embodiment, the states of the mahjong tiles in the first mahjong tile passage and the second mahjong tile passage can also be changed to each other. In short, the directions of the mahjong tiles in the first mahjong tile passage and the second mahjong tile passage need to be deflected, and after passing through the cleaning mechanism twice, all six surfaces are wiped clean.

[0090] In this embodiment, Figure 4a As shown, the driving system 70 for driving the mahjong tiles to move forward includes a first driving disc 71, a second driving disc 72 and a driving motor 73. The first driving disc 71 is provided with a first external gear 713, and the second driving disc 72 is provided with a second external gear 722 meshing with the first external gear 713, so that the first driving disc 71 and the second driving disc 72 rotate synchronously.

[0091] Preferably, in this embodiment, the second drive disk 72 is coaxially fixedly connected with a driven gear 75, and a driving gear 74 is connected to the output shaft of the drive motor 73. The driving gear 74 meshes with the driven gear 75, thereby driving the first drive disk 71 and the second drive disk 72 to rotate synchronously through the drive motor.

[0092] In this embodiment, the first driving disk 71 is rotatably connected to the bottom of the first track 50, wherein the bottom of the first track 50 is provided with a first track groove 51 extending along the first track, and correspondingly, the first driving disk 71 is evenly provided with a plurality of first card-pushing protrusions 711 protruding from the first track groove 51 to the first track 50 in the circumferential direction. The spacing between adjacent first card-pushing protrusions 711 is greater than the width of the mahjong tiles, and the mahjong tiles are driven to move in the first track 50 by the first card-pushing protrusions 711.

[0093] As a preferred embodiment, in this embodiment, Figure 4a , Figure 4b As shown, a radially extending mounting groove 712 is provided on the first driving disk 71 for mounting the first card-pushing protrusion 711, so that the radial position of the first card-pushing protrusion 711 on the first driving disk 71 is adjustable. Furthermore, a hinge column 714 penetrating the mounting groove 712 is provided at the bottom of the first card-pushing protrusion 711, so that the first card-pushing protrusion 711 can perform a combined movement in radial and rotational directions in the mounting groove 712. The purpose of such a setting is that the first track 50 and the first track groove 51 do not extend with equal diameters, and the first card-pushing protrusion 711 can adapt to the track change of the first track groove 51.

[0094] In this embodiment, the second driving disk 72 is rotatably connected to the bottom of the second track 60, wherein the bottom of the second track 60 is provided with a second track groove 61 extending along the second track. Accordingly, the second driving disk 72 is evenly provided with a plurality of second card-pushing protrusions 721 protruding from the second track groove to the second track in the circumferential direction. The spacing between adjacent second card-pushing protrusions 721 is greater than the length of the mahjong tiles, and the second card-pushing protrusions 721 drive the mahjong tiles to move in the second track 60.

[0095] In this embodiment, Figure 3As shown, the end of the first track 50 is connected to the second track 60. The mahjong tiles 100 enter the first track 50 from the card inlet 11, and are driven by the first card-pushing protrusion 711 to move in the first track 50 and pass through the first cleaning mechanism 201 until the end, and enter the second track 60. No special reversing structure is required to achieve the state switching of the mahjong tiles in the first track 50 and the second track 60. After the mahjong tiles enter the second track 60, the second card-pushing protrusion 721 drives the mahjong tiles to move in the second track 60 and pass through the second cleaning mechanism 202, and then leave the cleaning machine body 10 at the card outlet 12, completing the cleaning of the mahjong tiles.

[0096] In this embodiment, in order to make the mahjong tile 100 enter the first mahjong tile channel more smoothly, Figure 3 , Figure 5 , Figure 6 As shown, an inclined card entry slot 40 is also provided at the card entry end of the first mahjong card passage, i.e., the card entry opening 11, wherein the width of the card entry slot is adapted to the width of the first mahjong card passage. In this embodiment, the card entry guide slot 30 is hingedly connected to the card entry end of the card entry slot through a hinge structure 31, and the mahjong cards sequentially enter the first mahjong card passage through the card entry guide slot and the card entry slot.

[0097] Preferably, in this embodiment, a card sorting mechanism is provided on the card inlet slot 40. The card sorting mechanism includes a card leakage slot 42 provided on the slot bottom 41 of the card inlet slot and a card leakage channel 43 connected to the card leakage slot 42, and the card leakage channel 43 is connected to the outside of the cleaning machine body 10.

[0098] In this embodiment, the width of the card leakage groove 42 is between the length and width of the mahjong tile 100. Since, in this embodiment, the width of the first mahjong tile channel is adapted to the length of the mahjong tile, if the mahjong tile entering the card feed groove 40 from the card feed guide groove 30 is in a vertical direction, it will slide from the card leakage groove 42 along the card leakage channel 43 to the outside of the cleaning machine body 10.

[0099] As a preferred embodiment, in this embodiment, Figure 2 As shown, one side of the cleaning machine body 10 is provided with a card leakage opening 13 connected to the card leakage channel 43, and a flip cover 14 is hingedly connected to the card leakage opening 13. When the mahjong tiles in the card leakage channel 43 slide out of the card leakage opening 13, the flip cover 14 is pushed open. After the mahjong tiles fall down, the flip cover 14 is reset to cover the card leakage opening 13.

[0100] In this embodiment, Figure 5 , Figure 6As shown, a card dropping mechanism is provided between the end of the card input slot 40 and the first track 50. The card dropping mechanism includes a card dropping plate 80 hingedly provided with the card input slot 40, wherein an accommodating slot 44 for accommodating the card dropping plate 80 is provided at one end of the card input slot 40 close to the first track 50, and symmetrical first hinge holes 45 are provided on both sides of the accommodating slot 44.

[0101] In this embodiment, the structure of the card drop plate 80 is as follows: Figure 7 , Figure 8 As shown, a pair of symmetrical hinged parts 84 are provided, and a second hinged hole 85 is provided on the hinged part 84, which corresponds to the first hinged hole 45. A pin shaft connected to the first hinged hole 45 and the second hinged hole 85 can be provided, so as to realize the swinging action of the drop plate.

[0102] In this embodiment, the card drop plate 80 is provided with a card blocking edge 81 located at the hinged part near the card inlet slot, a card blocking part 82 located at the hinged part near the first track, and a card drop inclined surface 83 located at the card blocking part away from the hinged part. The end of the card drop plate near the first track is located on the motion track of the first card pushing protrusion.

[0103] like Fig. 9 As shown, mahjong tiles are arranged in the card feed slot, and the card blocking edge 81 protrudes from the bottom of the card feed slot, thereby preventing the mahjong tiles from sliding onto the first track. Fig.10 As shown, during the rotation of the first drive disk, when the first card-pushing protrusion 711 passes under the card-dropping plate 80, the first card-pushing protrusion 711 acts on the bottom of the card-dropping plate where the card-dropping inclined surface 83 is located, driving the card-dropping plate to rotate around the hinged position until the card-blocking edge 81 is lower than the bottom of the card-entering slot, wherein a mahjong tile slides onto the card-dropping plate, and the card-blocking portion 82 applies a certain limiting resistance to it. Then, after the first card-pushing protrusion 711 leaves the position where the card-dropping plate is located, under the action of the gravity of the mahjong tile, the card-dropping plate rotates around the hinged position until the card-blocking edge 81 protrudes from the bottom of the card-entering slot, blocking other mahjong tiles in the card-entering slot, and the sliding mahjong tiles fall into the first track. When the next first card-pushing protrusion 711 passes through the card-dropping plate again, the above-mentioned action is repeated, and the mahjong tile that has slid into the first track is driven to move along the first track.

[0104] The card dropping mechanism of this embodiment effectively controls the rhythm of the mahjong tiles entering the first track, so that the mahjong tiles enter the first track in an orderly manner, and prevents the mahjong tiles from gathering and clogging. It has the technical advantages of high cleaning efficiency and stable and reliable operation of the mahjong tile cleaning machine.

[0105] The present application is based on a mahjong tile cleaning machine of the second embodiment of the above-mentioned mahjong tile cleaning method.

[0106] In this embodiment, Fig.19 As shown, a card entry port 11 communicating with the upper mahjong track 101 is provided on the upper cover 110. Preferably, in order to facilitate card loading, in this embodiment, a card entry guide groove 30 is provided at a position on the upper cover 110 connected with the card entry port 11, and the width of the card entry guide groove 30 is adapted to the width of the upper mahjong track 101.

[0107] In this embodiment, Fig. 20 , Fig.24 As shown, the lower Mahjong tile track 105 is provided with a tile outlet 12 .

[0108] In this embodiment, the width of the upper mahjong tile track 101 is adapted to the length of the mahjong tile 100, and the width of the lower mahjong tile track 105 is adapted to the width of the mahjong tile 100. In this embodiment, a connecting port 102 is provided between the lower mahjong tile track 105 and the upper mahjong tile track 101, and a guide portion 104 for guiding the deflection of the mahjong tile 100 is provided in the upper mahjong tile track 101 at a position adjacent to the connecting port 102, and the guide portion 104 guides the mahjong tile to deflect approximately 90°.

[0109] In this embodiment, as a preference, the upper tile passage 11 is provided with a slope 103 at a position adjacent to the communication port 102, and the guide portion 104 is provided on the slope 103. The purpose of such a configuration is that the mahjong tiles 100 can slide from the upper tile track into the lower tile track under the action of their own weight, and deflect during the sliding process.

[0110] In this embodiment, Fig.19 , Fig.23 , Fig.24 As shown, the cleaning machine body 10 is provided with a mounting groove 107 for mounting the cleaning mechanism 20. The structure of a cleaning mechanism 20 of this embodiment is as follows Fig.26As shown, it includes a mechanism body 21, which is provided with an upper cleaning channel 241 located in the upper mahjong tile track and a lower cleaning channel 242 located in the lower mahjong tile track, wherein the upper cleaning channel 241 and the lower cleaning channel 242 respectively cover the three surfaces of the mahjong tiles. Specifically, the upper cleaning channel 241 covers the two end faces and the lower surface in the length direction of the mahjong tiles, and the lower cleaning channel 242 covers the two side faces and the upper surface in the width direction of the mahjong tiles. In this way, after the mahjong tiles pass through the upper cleaning channel 241 and the lower cleaning channel 242 in turn, the six surfaces can be cleaned.

[0111] It should be noted that, in this embodiment, the first cleaning mechanism in the upper mahjong tile track and the second cleaning mechanism in the lower mahjong tile track are integrated into one body, which is the preferred implementation of this embodiment. Of course, they can also be designed as separate and independent parts like the cleaning mechanism in the first embodiment.

[0112] In this embodiment, the inner surface of the cleaning channel of the cleaning mechanism 20 is provided with a flexible wiping material 26. The specific material is not limited in this embodiment, and any existing material that can be used to wipe mahjong tiles can be selected, including but not limited to sponges.

[0114] In this embodiment, Fig. 22 As shown, the upper driving plate 76 has a plurality of card receiving grooves 761 spaced apart along the circumferential direction in the upper mahjong tile track. The card receiving grooves 761 are used to accommodate mahjong tiles 100 and to drive the mahjong tiles 100 to move in the upper mahjong tile channel.

[0115] In this embodiment, a motor installation cavity 762 for accommodating the drive motor 73 is further provided at the center of the upper drive disk 76, so that the structure is more compact and the space utilization rate is higher.

[0116] In this embodiment, Fig.25 As shown, the lower driving disk 77 is arranged below the lower mahjong tile track, and the upper surface of the lower driving disk is also evenly provided with a plurality of driving tile convex strips 771 in the circumferential direction for driving the mahjong tiles to move in the lower mahjong tile track.

[0117] Preferably, in this embodiment, a plurality of rollers 772 are evenly distributed along the circumferential direction at the bottom of the lower driving disk 77, and the rollers 772 are in contact with the upper surface of the base 120, so that the running resistance of the lower driving disk 77 is smaller and the power consumption of the driving motor is smaller.

[0118] In the mahjong tile cleaning machine of this embodiment, the mahjong tiles enter the upper mahjong tile track from the card feed guide groove in the first state, and after the three surfaces are wiped by the cleaning mechanism in the upper mahjong tile track, the mahjong tiles pass through the guide part to make the mahjong machine deflect by a certain angle, and then enter the lower mahjong tile track in the second state, and after the remaining three surfaces are wiped by the cleaning mechanism, they exit the cleaning machine from the card outlet.

[0119] The mahjong tile cleaning machine of this embodiment has the advantages of being compact and occupying little space due to its vertical structure and non-layout form.

[0120] In short, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
