Description

Technical Field

[0001] The invention relates to the technical field of electric heating, in particular to a heating structure of an electric heating mahjong machine. Background Art

[0002] The heating structure of the electric heating mahjong machine is a device for heating. Since the indoor temperature is low in winter, a heating structure is set on the mahjong machine to improve comfort. The heating structure is mainly designed around the arrangement and fixing method of the electric heating elements and related auxiliary equipment. The number and arrangement method are set according to the size of the mahjong machine and the heating requirements. The common arrangement method is to arrange four electric heating elements along the diagonal of the rectangular structure on the lower surface of the mahjong table operating table. In order to better fix and install auxiliary equipment such as thermostats and temperature sensors, the columns of the electric heating mahjong machine usually adopt hollow structures. These hollow structures constitute installation chambers for accommodating these devices. In order to prevent safety problems caused by overheating of the electric heating elements, some electric heating mahjong machines are also equipped with overheating protection modules. When the temperature is too high, the overheating protection module will automatically cut off the power supply of the electric heating elements to ensure safe use.

[0003] During the use of the electric heating mahjong machine, different users will sit in different positions and place their legs under the electric heating mahjong machine. The existing electric heating mahjong machines usually use electric heating elements to directly generate heat for heating. The heat transfer is relatively direct, and the area of ​​the electric heating elements is limited, making it difficult to fully heat the entire area under the electric heating mahjong machine. The electric heating elements are usually fixedly installed under the mahjong machine, resulting in a single part of the user's leg being continuously heated, making it difficult for the user's entire leg to feel enough heat. When the electric heating mahjong machine works for a long time, the electric heating unit continues to work, and a single part of the user's leg may be heated too much and feel overheated, while other parts of the leg may not be heated enough and still feel cold. For this reason, we propose a heating structure for an electric heating mahjong machine. Summary of the invention

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figure 1-14The present invention provides a technical solution: a heating structure of an electric heating mahjong machine, comprising a body 1, a support tube 2 is fixedly installed at the lower end of the body 1, a bottom plate 3 is fixedly installed at the lower end of the support tube 2, four side columns 4 are fixedly connected between the body 1 and the bottom plate 3, the side columns 4 are respectively located at the four corners of the body 1, a connecting tube 32 is fixedly connected between each side column 4 and the support tube 2, a motor 9 is fixedly installed on the top of the support tube 2, a bevel gear disc 10 is fixedly installed at the output end of the motor 9, and a rotating device is installed in each connecting tube 32. There are rotating rods 12, each of which has a bevel gear 11 meshing with the bevel gear disc 10 fixedly mounted on one end, and the other end is inserted into the corresponding side column 4 and fixedly mounted with a sprocket wheel 13. Several fans 14 are rotatably mounted inside each side column 4, and a sprocket wheel 13 is also fixedly mounted on each fan 14. A chain 15 is installed between the sprocket wheels 13 for transmission. A heating tube 16 is fixedly mounted inside each side column 4. When the mahjong machine is used, the motor 9 will start and drive the bevel gear disc 10 at its output end to rotate. Rotation, through the meshing of the bevel gear 10 and the bevel gear 11, the bevel gear 11 will be driven to rotate, and through the transmission of the sprocket wheel 13 and the chain 15, the fan 14 will be driven to rotate, and the heating tube 16 will generate heat at the same time, and the fan 14 will blow the heat generated by the heating tube 16 to the user, and each side column 4 is fixedly installed with two warm cloths 5 through Velcro 6, and the upper end of each warm cloth 5 is adhered to the lower end of the main body 1 through a magnetic strip 7, and each side of each corresponding warm cloth 5 is fixedly installed with a magnetic strip 7 that attracts each other. The warm cloth 5 gathers the heat generated by the heating tube 16 under the main body 1. After the user puts the legs under the main body 1, the warm cloths 5 on both sides are adhered and attracted by the magnetic strip 7 and closed, and the user's legs are wrapped, thereby improving the warmth retention. A number of heat dissipation grooves 8 are arranged on all four sides of the support tube 2, and each heat dissipation groove 8 opens upward. Since the hot air moves upward in the air, the heat generated by the motor 9 is discharged through the heat dissipation groove 8, and since the opening is facing upward, the fan 14 can reduce the heat of the heating tube 16 from blowing into the support tube 2.

[0036] A rotating shaft 23 is rotatably installed in each connecting cylinder 32, and each rotating shaft 23 is driven to rotate by the corresponding rotating rod 12. A rotating disk 24 is fixedly installed at one end of each rotating shaft 23, and a connecting rod 25 is rotatably installed on each rotating disk 24. Each connecting rod 25 is eccentrically arranged on the rotating disk 24, and a sliding rod 26 is rotatably installed at one end of each sliding rod 26. A limiting block 27 is fixedly installed at one end of each sliding rod 26. A guide frame 17 is fixedly installed on each side column 4, and a plurality of guide plates 18 are rotatably installed on each guide frame 17. A transmission roller 19 is fixedly installed on the upper end of each guide plate 18, and a connecting belt 20 is installed between the transmission rollers 19 for transmission. A slide plate 21 is fixedly installed on each connecting belt 20, and each slide plate 21 is provided with an oblique groove 22 for limiting the limiting block 27. A slide groove 28 for limiting the slide bar 26 is provided on each guide frame 17. When the rotating shaft 23 rotates, the belt As the rotating disk 24 rotates, one end of the connecting rod 25 will move in a circle with it. Since one end of the connecting rod 25 is rotatably connected to the sliding rod 26, and the sliding rod 26 is limited by the sliding groove 28, one end of the connecting rod 25 will drive the sliding rod 26 to reciprocate up and down along the sliding groove 28, and the upper limit block 27 of the sliding rod 26 is limited by the oblique groove 22 on the slide plate 21. As the sliding rod 26 drives the limit block 27 to reciprocate up and down, it will drive the slide plate 21 to reciprocate laterally, and the slide plate 21 will drive the connecting belt 20 to reciprocate. Through the transmission of the connecting belt 20 and the transmission roller 19, the transmission roller 19 will drive the guide plate 18 to reciprocate a certain amplitude. The guide plate 18 guides the hot air blown out by the fan 14, so that the hot air is reciprocated and blows to the users on both sides of the corresponding side column 4, thereby improving the flow of heat below the body 1, making the user's legs more evenly heated, and avoiding heating a single part of the user.

[0037] Two gear sets 41 are fixedly mounted on each rotating rod 12, each gear set 41 is composed of a plurality of gears 42, and the gears 42 are arranged according to the size of the radius. Two half gear sets 43 are arranged on each rotating shaft 23, and the two half gear sets 43 are respectively located on both sides of the rotating shaft 23. Each half gear set 43 is composed of a plurality of half gears 44, and the half gears 44 are also arranged according to the size of the radius. The convex teeth on both sides of each half gear 44 and the convex teeth on both sides of each gear 42 are arranged in a wedge shape to reduce the friction caused by the collision when the half gears 44 and the gears 42 are meshed. A limiting member 46 is arranged on each of the half gears 44, and a connecting plate 49 is fixedly mounted on each half gear 44, and each connecting plate 49 is located in the limiting member 46, and each connecting plate A third spring 50 is fixedly connected between the two sides of the plate 49 and the inner walls on both sides of the limiter 46. A plurality of limit grooves 45 for limiting the limiter 46 are arranged on each rotating shaft 23, and the limit grooves 45 correspond to the limiter 46 one by one. A plurality of fixed plates 47 are fixedly installed inside the rotating shaft 23, and the fixed plates 47 correspond to the limit grooves 45 one by one. A second spring 48 is fixedly connected between each limiter 46 and the corresponding fixed plate 47. Cylinders 51 are fixedly installed on the inner walls at both ends of the rotating shaft 23, and an elastic plate 52 for pushing the limiter 46 is fixedly installed on the output end of each cylinder 51. The rigidity of the elastic plate 52 is greater than that of the second spring 48. The cylinder 51 works and extends a certain length to push the elastic plate 52 to move the corresponding limiter The part 46 is pushed along the front end of the limiting groove 45 to the rear end. Since the rigidity of the elastic plate 52 is greater than that of the second spring 48, the second spring 48 will be stretched, while the elastic plate 52 will not be deformed. The limiting part 46 will drive its upper half gear 44 to move along the rotating shaft 23 and mesh with the corresponding gear 42. When there is an error in the meshing, the connecting plate 49 will slide in the limiting part 46, and the corresponding half gear 44 will rotate relative to the rotating shaft 23 to a certain extent, and the third springs 50 on both sides thereof will be compressed and stretched accordingly. The half gear 44 will deviate to a certain extent, meshing with the gear 42, so that the rotating rod 12 can drive the rotating shaft 23 to rotate. Since the two half gear sets 43 are respectively located on both sides of the rotating shaft 23, when the rotating shaft 23 After the half gear 44 on one side is meshed with the corresponding gear 42, the half gear 44 on the other side will mesh with the corresponding gear 42, so that the rotating shaft 23 rotates continuously. When the temperature required by the user is inconsistent, the cylinder 51 in the rotating shaft 23 will extend to different lengths. After the elastic plate 52 pushes the limiter 46 to the end of the corresponding limiter groove 45, when the cylinder 51 pushes the elastic plate 52 to extend again, the limiter 46 cannot slide, and the elastic plate 52 will deform. After passing through the limiter 46, its elasticity makes it recover its deformation. The limiter 46 drives the corresponding half gear 44 to retract elastically under the second spring 48, and the meshing of the corresponding half gear 44 and the gear 42 is released. At the same time, the elastic plate 52 pushes the next limiter 46 to overcome the elastic force of the second spring 48 to move.The corresponding half gear 44 is meshed with the corresponding gear 42. When the two pairs of gears 42 and the half gear 44 meshed on the rotating shaft 23 have different sizes, due to the different radii of the half gear 44 and the gear 42, the rotation speed of the rotating shaft 23 will change every half circle. When one pair of half gears 44 is meshed with the gear 42, the rotation speed of the rotating shaft 23 is faster, and when the other pair of half gears 44 is meshed with the gear 42, the rotation speed of the rotating shaft 23 is slower, and the rotation speed of the turntable 24 will also change accordingly. When the slide bar 26 reciprocates up and down, the speed of the upward movement and the upward movement will change, so that the time for the guide plate 18 to guide heat to the users on both sides during the diversion process is changed. Users who need more heat can make the guide plate 18 rotate slowly when guiding hot air to them, so that more hot air is blown to their area, and users who need less heat can make the guide plate 18 rotate faster when guiding hot air to them, so that less hot air is blown to their area. ,

[0038] Adjustment grooves 31 are provided on the four sides of the support cylinder 2, and an adjustment block 29 is slidably installed in each adjustment groove 31, and an adjustment piece 33 is fixedly installed on each adjustment block 29. Each adjustment piece 33 is located in the support cylinder 2, and a limit rod 36 is slidably installed on both sides thereof. A plurality of limit plates 38 are fixedly installed on the inner wall of the support cylinder 2, and the limit plates 38 are respectively located on both sides of the adjustment piece 33, and a plurality of limit holes 39 for limiting the limit rod 36 are provided thereon, and a sensing piece 40 for controlling the cylinder 51 is fixedly installed on the inner wall of each limit hole 39, and a device block 30 is slidably installed on each adjustment block 29, and a wedge plate 34 is fixedly connected to one end of each device block 30, and each wedge plate 34 is located in the corresponding adjustment piece 33, and one end thereof is set to be a two-sided wedge, and a wedge block 35 matching the wedge plate 34 is fixedly installed on one end of each limit rod 36, and each two corresponding The wedge blocks 35 are fixedly connected with a first spring 37, which pushes the device block 30 into the inside of the adjustment block 29. The device block 30 drives the wedge plate 34 to move in the adjustment member 33. The two wedge blocks 35 are relatively moved by the cooperation of the inclined surfaces on both sides of the wedge plate 34 and the inclined surfaces of the wedge blocks 35 on both sides thereof, and the first spring 37 is compressed, and at the same time, the limiting rods 36 on both sides are driven to move into the adjustment member 33. After the limiting rods 36 are separated from the limiting position of the limiting holes 39, they push the adjustment block 29 to move along the adjustment slot 31. After the limiting rods 36 are aligned with the required limiting holes 39, the device block 30 is no longer pushed. The elastic force of the first spring 37 makes the limiting rods 36 extend again and reset the wedge plate 34 and the device block 30. After the limiting rods 36 are inserted into the corresponding limiting holes 39, the corresponding sensing parts 40 are sensed, and the corresponding cylinders 51 on both sides of the user will extend a specified length to adjust the hot air input amount in the area where the user is located.

[0039] Specifically, when the mahjong machine is used, the motor 9 will start and drive the bevel gear disc 10 at its output end to rotate. The bevel gear disc 10 is meshed with the bevel gear 11, which drives the bevel gear 11 to rotate. The transmission of the sprocket wheel 13 and the chain 15 will drive the fan 14 to rotate. At the same time, the heating tube 16 generates heat. The fan 14 blows the heat generated by the heating tube 16 to the user. The user can use his feet to push the device block 30 into the inside of the adjustment block 29. The device block 30 drives the wedge plate 34 to move in the adjustment member 33. Through the cooperation of the inclined surfaces on both sides of the wedge plate 34 and the inclined surfaces of the wedge blocks 35 on both sides thereof, the two wedge blocks 35 move relative to each other, and the first spring 37 is compressed, and at the same time, the limit rods 36 on both sides are driven to move into the adjustment member 33. After the limiting rod 36 is released from the limiting hole 39, it pushes the adjustment block 29 to move along the adjustment slot 31. After the limiting rod 36 is aligned with the required limiting hole 39, the device block 30 is no longer pushed. The elastic force of the first spring 37 makes the limiting rod 36 extend again and reset the wedge plate 34 and the device block 30. After the limiting rod 36 is inserted into the corresponding limiting hole 39, the corresponding sensing member 40 is sensed, and the corresponding cylinders 51 on both sides of the user will extend the specified length. The elastic plate 52 is pushed by the cylinder 51 to push the corresponding limiting member 46 along the head end of the limiting slot 45 to the end. Since the rigidity of the elastic plate 52 is greater than that of the second spring 48, the second spring 48 will be stretched, while the elastic plate 52 will not be deformed, and the limiting member 46 will drive its upper half gear 44 along the rotating shaft 23 moves and meshes with the corresponding gear 42. When there is an error in the meshing, the connecting plate 49 will slide in the limiter 46, and the third springs 50 on both sides thereof will be compressed and stretched accordingly, and the half gear 44 will be offset to a certain extent, so that it meshes with the gear 42, so that the rotating rod 12 can drive the rotating shaft 23 to rotate. Since the two half gear sets 43 are respectively located on both sides of the rotating shaft 23, when the half gear 44 on one side of the rotating shaft 23 is meshed with the corresponding gear 42, the half gear 44 on the other side will mesh with the corresponding gear 42, so that the rotating shaft 23 rotates continuously. When the user requires different temperatures, the cylinder 51 in the rotating shaft 23 will extend to different lengths, and the elastic plate 52 will push the limiter 46 to the end of the corresponding limit slot 45 After the end, when the cylinder 51 pushes the elastic plate 52 to extend again, the limiter 46 cannot slide, and the elastic plate 52 will be deformed. After passing through the limiter 46, its elasticity makes it recover its deformation. The limiter 46 drives the corresponding half gear 44 to retract elastically due to the second spring 48, and the meshing of the corresponding half gear 44 and the gear 42 is released. At the same time, the elastic plate 52 pushes the next limiter 46 to overcome the elastic force of the second spring 48 to make the corresponding half gear 44 mesh with the corresponding gear 42. When the two pairs of gears 42 and the half gears 44 meshing on the rotating shaft 23 are of different sizes, due to the different radii of the half gears 44 and the gear 42, the rotation speed of the rotating shaft 23 will change every half turn. When a pair of half gears 44 mesh with the gear 42, the rotating shaft 23 rotates faster.When the other pair of half gears 44 meshes with the gear 42, the rotation speed of the shaft 23 is slower. When the rotating rod 12 drives the shaft 23 to rotate, it will drive the turntable 24 to rotate, and one end of the connecting rod 25 will perform circular motion therewith. Since one end of the connecting rod 25 is rotatably connected with the sliding rod 26, and the sliding rod 26 is limited by the sliding groove 28, one end of the connecting rod 25 will drive the sliding rod 26 to reciprocate up and down along the sliding groove 28. The upper limit block 27 of the sliding rod 26 is limited by the oblique groove 22 on the slide plate 21. As the sliding rod 26 drives the limit block 27 to reciprocate up and down, it will drive the slide plate 21 to reciprocate laterally. The slide plate 21 will drive the connecting belt 20 to reciprocate. Through the transmission of the connecting belt 20 and the transmission roller 19, the transmission roller 19 will drive the guide plate 18 The guide plate 18 guides the hot air blown out by the fan 14 with a certain amplitude of reciprocating rotation, so that the hot air is blown back and forth to the users on both sides of the corresponding side column 4. When the rotation speed of the rotating shaft 23 changes, the rotation speed of the turntable 24 will also change accordingly. When the slide bar 26 reciprocates up and down, the speed of the upward movement and the upward movement will change, so that the time for the guide plate 18 to guide heat to the users on both sides during the diversion process changes. Users who need more heat can make the guide plate 18 rotate slowly when guiding the hot air to them, so that more hot air is blown to their area.
