Description

Technical Field

[0001] This utility model relates to the field of mahjong tile cleaning technology, specifically to a mahjong tile cleaning machine. Background Technology

[0002] Due to the recreational nature of mahjong tiles, they are touched by many people in a short period of time, causing dust, sweat, bacteria, and other contaminants to accumulate on their surface. This is especially true in card and board game rooms, where the hygiene of the mahjong tiles is even more concerning. Currently, card and board game rooms typically clean the surface of the mahjong tiles regularly by wiping them manually. However, this manual cleaning method is labor-intensive, inefficient, and the efficiency varies greatly among different staff members.

[0003] To address this manual cleaning method, some patent documents have disclosed mahjong tile cleaning machines. For example, CN211160821 discloses a mahjong tile cleaning machine that uses a complex brush roller layout to clean the surface of the mahjong tiles. However, this method cannot guarantee that all six surfaces of the mahjong tiles are cleaned thoroughly, and the tiles are prone to accumulating and causing the machine to jam.

[0004] For example, a mahjong cleaning device disclosed in announcement number CN211247484U also has the defects of complex structure, inability to ensure that all six surfaces of the mahjong tiles are cleaned, and mahjong tiles gathering and causing the machine to jam. Summary of the Invention

[0044] This embodiment provides a mahjong tile cleaning machine, such as... Figure 1 , Figure 2 As shown, the machine includes a cleaning machine body 10, with a card inlet 11 at the top and a card outlet 12 on the side near the bottom. Mahjong tiles 100 enter the cleaning machine body 10 through the card inlet 11 and exit through the card outlet 12.

[0045] Preferably, in this embodiment, a card-feeding guide groove 30, hinged to the main body 10 of the cleaning machine, is provided at the card-feeding inlet 11. The width of the card-feeding guide groove 30 is adapted to the length of the mahjong tiles 100. In this embodiment, the function of the card-feeding guide groove 30 is to facilitate the user to regularly feed the mahjong tiles into the main body 10 of the cleaning machine from the card-feeding inlet 11. Since the card-feeding guide groove 30 is hinged, it can be extended to [a certain position] when cleaning the mahjong tiles. Figure 1 As shown, when not in use, it folds to... Figure 2 The state shown makes the mahjong tile cleaner occupy less space and easier to store; at the same time, the tile guide groove 30 covers the tile inlet 11 when folded, which can effectively prevent debris from entering the interior of the cleaner body 10 from the tile inlet 11.

[0046] In this embodiment, as Figure 3As shown, the interior of the cleaning machine body 10 has two horizontally parallel mahjong tile cleaning areas: a first cleaning area connected to the tile inlet 11 and a second cleaning area connected to the tile outlet 12. In the first cleaning area, an arc-shaped first track 50 is provided, forming a first mahjong tile channel between the first track 50 and the outer shell of the cleaning machine body 10, accommodating the movement of the mahjong tiles 100. 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.

[0047] In this embodiment, an arc-shaped second track 60 is provided in the second cleaning area, forming a second mahjong tile channel between the second track 60 and the outer shell of the cleaning machine body 10 to accommodate the movement of the mahjong tiles 100. The width of the second mahjong tile channel (i.e., the width of the second track 60) is adapted to the width of the mahjong tiles 100.

[0048] In this embodiment, as Figure 1-3 As shown, in this embodiment of the mahjong tile cleaning machine, 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 channel, and a second cleaning mechanism 202 is provided on the second mahjong tile channel.

[0049] The cleaning mechanism 20 in this embodiment is as follows: Figure 12-18 As shown, the device includes a main body 21, with a cleaning channel 24 for accommodating mahjong tiles on one side and a liquid replenishment chamber 211 on the side of the main body 21 away from the cleaning channel 24.

[0050] In this embodiment, the cleaning channel 24 is provided with four wiping surfaces: a first wiping surface 241 located on one side of the main body 21, a second wiping surface 242 and a third wiping surface 243 extending from both ends of the first wiping surface 241 away from the main body 21, and a fourth wiping surface 244 disposed opposite to the first wiping surface 241. Each wiping surface is provided with a flexible wiping material 26. This embodiment does not limit the specific material used; any existing material suitable for wiping mahjong tiles can be used, including but not limited to sponges.

[0051] In this embodiment, preferably, a through groove 25 is provided on the fourth wiping surface 244, extending through the fourth wiping surface along the extension direction of the cleaning channel. The through groove 25 facilitates driving the mahjong tiles through the cleaning channel 24.

[0052] In this embodiment, as Figure 17As shown, the surface of the cleaning channel 24 is provided with a mounting groove 261 for mounting the wiping material 26. The mounting groove 261 has retaining edges 262 on both the side near the through groove 25 and the rear side (the side where the mahjong tile leaves the cleaning channel). Alternatively, retaining edges can also be provided on the front side of the mounting groove 261 (the side where the mahjong tile enters the cleaning channel).

[0053] As a special feature of this embodiment, a fluid replenishment mechanism for replenishing the cleaning fluid is also included. In this embodiment, as... Figure 12-17 As shown, the replenishment mechanism includes a liquid storage tank 221 disposed on the side of the main body of the mechanism away from the cleaning channel. The liquid storage tank 221 is provided with a sliding part 222 that is slidably connected to the replenishment chamber 211. A guide structure is provided between the sliding part 222 and the inner wall of the replenishment chamber 211. Preferably, in this embodiment, the guide structure includes a plurality of guide grooves 224 vertically disposed on the sliding part 222 and a guide protrusion 213 disposed on the inner wall of the replenishment chamber and slidably adapted to the guide grooves 224. Preferably, guide structures are distributed between the sliding part 222 and the replenishment chamber on opposite sides.

[0054] Furthermore, such as Figure 15 , Figure 18 As shown, a limiting step 226 is provided at one end of the guide groove 224 near the main body of the mechanism. The limiting step 226 and the guide protrusion 213 form a limiting mechanism to prevent the liquid storage tank from separating from the liquid replenishment chamber.

[0055] In this embodiment, as Figure 14 , Figure 16 As shown, the outlet 223 of the liquid storage tank 221 faces the bottom of the replenishment chamber 211, and the outlet 223 is equipped with a one-way valve 27. It should be noted that the structure of this one-way valve is prior art and will not be described in detail here. Under normal conditions, the one-way valve 27 closes the outlet 223. When the one-way valve 27 is pressed, the outlet 223 is opened, and the cleaning fluid in the liquid storage tank can flow into the replenishment chamber.

[0056] In this embodiment, as Figure 17 As shown, the main body 21 of the mechanism is provided with several liquid replenishment holes 214 that connect the liquid replenishment chamber 211 and the wiping material 26. The cleaning liquid in the liquid replenishment chamber flows to the wiping material through the liquid replenishment holes 214 and penetrates the wiping material, thereby improving the cleaning effect of the mahjong tiles.

[0057] In this embodiment, as Figure 17 As shown, the bottom of the fluid replenishment chamber 211 is provided with a protrusion 212 that abuts against the one-way valve 27, and a plurality of protrusions 215 are provided around the protrusion 212, which form the spring mounting part of this embodiment.

[0058] In this embodiment, a boss 225 is provided on the side of the liquid storage tank 221 facing the liquid replenishment chamber, and the liquid outlet is provided on the boss 225. Furthermore, in this embodiment, an elastic element is provided between the bottom of the liquid storage tank and the liquid replenishment chamber. Preferably, this elastic element is a spring 28, one end of which is sleeved on the boss 225, and the other end is mounted on a spring mounting portion.

[0059] The mahjong tile cleaning mechanism in this embodiment, in its natural state, is as follows: Figure 12-15 As shown, the outlet is closed by a one-way valve. When the mahjong tiles pass through the cleaning channel, the outer surfaces of the tiles that come into contact with each wiping surface are cleaned by that surface. Further, by pressing the storage tank... Figure 16 In the indicated state, the outlet is open, allowing cleaning fluid from the reservoir to flow into the replenishment chamber. The cleaning fluid in the replenishment chamber then permeates through the replenishment hole onto the wiping material, enhancing the cleaning effect. Upon releasing the pressure, the reservoir returns to its original position under spring pressure. Figure 12-15 In this state, the outlet is closed by a one-way valve.

[0060] In this embodiment, in the first cleaning mechanism 201, the width of the cleaning channel 24 is adapted to the length of the mahjong tile 100. When the mahjong tile passes through the cleaning channel 24 of the first cleaning mechanism 201, its upper and lower surfaces (formed by its length and width), and its two end surfaces (formed by its width and height), totaling four surfaces, are wiped clean. When the mahjong tile passes through the second cleaning mechanism 202 in the second cleaning area, since the width of the cleaning channel of the second cleaning mechanism 202 is adapted to the width of the mahjong tile, its upper and lower surfaces (formed by its length and width), and its two side surfaces (formed by its length and height), totaling four surfaces, are wiped clean. Thus, after the mahjong tile passes through the first cleaning mechanism 201 and the second cleaning mechanism 202 in sequence, all six surfaces are wiped clean, thereby achieving the purpose of thoroughly cleaning the surface of the mahjong tile and changing the cleaning method of existing mahjong tile cleaning machines. Its advantage is that the mahjong tile passes through the first and second cleaning areas in a regular sequence, preventing mahjong tile accumulation and blockage.

[0061] It should be noted that, although in this embodiment, both the first cleaning mechanism 201 and the second cleaning mechanism 202 have four wiping surfaces in their cleaning channels 24, as a feasible implementation, the first cleaning mechanism 201 can also have three wiping surfaces in its cleaning channel 24: a second wiping surface 242, a third wiping surface 243, and a fourth wiping surface 244; correspondingly, the second cleaning mechanism 202's cleaning channel 24 still has four wiping surfaces. With this 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 all six surfaces are wiped clean, thereby achieving the purpose of thoroughly cleaning the surface of the mahjong tiles.

[0062] Furthermore, it should be noted that in this embodiment, the width of the first mahjong tile channel is adapted to the length of the mahjong tile, and the width of the second mahjong tile channel is adapted to the width of the mahjong tile. As an equivalent implementation, the state of the mahjong tile within the first and second mahjong tile channels can also change. In short, the orientation of the mahjong tile in the first and second mahjong tile channels needs to be deflected so that all six surfaces are wiped clean after passing through the cleaning mechanism twice.

[0063] In this embodiment, as Figure 4a As shown, the drive system 70 for driving the mahjong tiles includes a first drive disk 71, a second drive disk 72, and a drive motor 73. The first drive disk 71 is provided with a first external gear 713, and the second drive disk 72 is provided with a second external gear 722 that meshes with the first external gear 713, so that the first drive disk 71 and the second drive disk 72 rotate synchronously.

[0064] Preferably, in this embodiment, the second drive disk 72 is coaxially fixedly connected to the driven gear 75, and the output shaft of the drive motor 73 is connected to the driving gear 74. 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.

[0065] In this embodiment, the first drive disk 71 is rotatably connected to the lower part of the first track 50. The bottom of the first track 50 is provided with a first track groove 51 extending along the first track. Correspondingly, the first drive disk 71 is evenly distributed with a plurality of first push-tile protrusions 711 protruding from the first track groove 51 and extending out of the first track 50 along the circumferential direction. The distance between adjacent first push-tile protrusions 711 is greater than the width of the mahjong tile, and the first push-tile protrusions 711 drive the mahjong tile to move within the first track 50.

[0066] As a preferred embodiment, in this case, Figure 4a , Figure 4b As shown, the first drive disk 71 has a radially extending mounting groove 712 for mounting the first pusher protrusion 711, making the radial position of the first pusher protrusion 711 on the first drive disk 71 adjustable. Further, the bottom of the first pusher protrusion 711 is provided with a hinge post 714 penetrating the mounting groove 712, allowing the first pusher protrusion 711 to perform a combination of radial and rotational movements within the mounting groove 712. The purpose of this arrangement is that the first track 50 and the first track groove 51 are not of equal diameter, allowing the first pusher protrusion 711 to adapt to changes in the trajectory of the first track groove 51.

[0067] In this embodiment, the second drive disk 72 is rotatably connected to the lower part 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. Correspondingly, the second drive disk 72 is provided with a plurality of second push-tile protrusions 721 evenly distributed along the circumferential direction, protruding from the second track groove and extending from the second track. The distance between adjacent second push-tile protrusions 721 is greater than the length of the mahjong tile, and the second push-tile protrusions 721 drive the mahjong tile to move in the second track 60.

[0068] In this embodiment, as Figure 3 As shown, the end of the first track 50 is connected to the second track 60. Mahjong tiles 100 enter the first track 50 through the inlet 11, are driven by the first pusher 711 to travel within the first track 50, pass through the first cleaning mechanism 201, and then enter the second track 60. No special reversing structure is needed to switch the state of the mahjong tiles between the first track 50 and the second track 60. After entering the second track 60, the second pusher 721 drives the mahjong tiles to travel within the second track 60, pass through the second cleaning mechanism 202, and then exit the cleaning machine body 10 through the outlet 12, completing the cleaning of the mahjong tiles.

[0069] In this embodiment, in order to allow the mahjong tile 100 to enter the first mahjong tile channel more smoothly, such as Figure 3 , Figure 5 , Figure 6 As shown, an inclined card-feeding slot 40 is also provided at the card-feeding end, i.e., the card-feeding opening 11, of the first mahjong tile channel. The width of the card-feeding slot is adapted to the width of the first mahjong tile channel. In this embodiment, the card-feeding guide slot 30 is hinged to the card-feeding end of the card-feeding slot via a hinge structure 31. The mahjong tiles enter the first mahjong tile channel sequentially through the card-feeding guide slot and the card-feeding slot.

[0070] Preferably, in this embodiment, the card feeding slot 40 is provided with a card sorting mechanism. The card sorting mechanism includes a card leakage slot 42 disposed on the bottom 41 of the card feeding slot and a card leakage channel 43 communicating with the card leakage slot 42, the card leakage channel 43 communicating with the outside of the washing machine body 10.

[0071] In this embodiment, the width of the card-draining groove 42 is between the length and width of the mahjong tile 100. Since the width of the first mahjong tile channel is adapted to the length of the mahjong tile in this embodiment, if the mahjong tile entering the card-feeding groove 40 from the card-feeding guide groove 30 is in a vertical direction, it will slide down from the card-draining groove 42 along the card-draining channel 43 to the outside of the washing machine body 10.

[0072] As a preferred embodiment, in this case, Figure 2As shown, a tile-leaking opening 13 is provided on one side of the main body 10 of the cleaning machine, which is connected to the tile-leaking channel 43. A flip cover 14 is hinged to the tile-leaking opening 13. When the mahjong tiles in the tile-leaking channel 43 slide out of the tile-leaking opening 13, the flip cover 14 is opened. After the mahjong tiles fall, the flip cover 14 returns to its original position to cover the tile-leaking opening 13.

[0073] In this embodiment, as Figure 5 , Figure 6 As shown, a card-dropping mechanism is provided between the end of the card-feeding slot 40 and the first track 50. The card-dropping mechanism includes a card-dropping plate 80 hinged to the card-feeding slot 40, wherein a receiving groove 44 for accommodating the card-dropping plate 80 is provided at one end of the card-feeding slot 40 near the first track 50, and symmetrical first hinge holes 45 are provided on both sides of the receiving groove 44.

[0074] In this embodiment, the structure of the card-dropping plate 80 is as follows: Figure 7 , Figure 8 As shown, a pair of symmetrical hinge portions 84 are provided, and each hinge portion 84 has a second hinge hole 85 corresponding to the position of the first hinge hole 45. A pin can be provided to connect to both the first hinge hole 45 and the second hinge hole 85, thereby realizing the swinging motion of the card-dropping plate.

[0075] In this embodiment, the card-dropping plate 80 is provided with a card-blocking edge 81 located on the side of the hinge portion near the card-feeding slot, a card-blocking part 82 located on the side of the hinge portion near the first track, and a card-dropping inclined surface 83 located on the side of the card-blocking part away from the hinge portion. The end of the card-dropping plate near the first track is located on the movement trajectory of the first card-pushing protrusion.

[0076] like Figure 9 As shown, the mahjong tiles are arranged in the tile-feeding slot, and the tile-blocking edge 81 protrudes from the bottom of the slot, thus preventing the mahjong tiles from sliding onto the first track. Figure 10 As shown, during the rotation of the first drive disc, when the first pusher protrusion 711 passes below the tile-dropping plate 80, it acts on the bottom of the tile-dropping plate at the location of the tile-dropping slope 83, driving the tile-dropping plate to rotate around the hinged position until the tile-blocking edge 81 is lower than the bottom of the tile-feeding slot. A mahjong tile slides onto the tile-dropping plate, where the tile-blocking part 82 applies a certain limiting resistance. Then, after the first pusher protrusion 711 leaves the tile-dropping plate, the tile-dropping plate rotates around the hinged position under the weight of the mahjong tile until the tile-blocking edge 81 protrudes beyond the bottom of the tile-feeding slot, blocking other mahjong tiles in the slot, while the sliding mahjong tile falls into the first track. When the next first pusher protrusion 711 passes the tile-dropping plate, the above action is repeated, driving the mahjong tile that previously slid into the first track to move along the first track.

[0077] The tile-dropping mechanism in this embodiment effectively controls the rhythm of the mahjong tiles entering the first track, ensuring that the mahjong tiles enter the first track in an orderly manner and preventing the mahjong tiles from gathering and blocking. It has the technical advantages of high cleaning efficiency and stable and reliable operation of the mahjong tile cleaning machine.

[0078] In summary, the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
