Description
TECHNICAL FIELD
[0001] The present application relates to a power tool, in particular to a power tool system. BACKGROUND
[0002] A power tool in the related art is a ceramic tile tiler, which can move a ceramic tile to a tiling position after adsorbing the ceramic tile by a suction cup. After the ceramic tile is moved to the tiling position, the ceramic tile tiler makes the ceramic tile vibrate at a high frequency to discharge air under the ceramic tile and flatten cement, thereby completing tiling of the ceramic tile and reducing the hollow rate. Compared with the traditional manual tiling method by using a rubber hammer to knock the ceramic tile, the ceramic tile tiler has high efficiency, saves time and effort, and has high stability and high tiling flatness.
[0003] The existing ceramic tile tiler generally uses a battery pack for power supply to avoid the influence of a pull line external power supply on convenience. The battery pack is generally installed at a handle of the ceramic tile tiler, and there is a certain difficulty in cooperation between the battery pack and the handle. If the cooperation gap is too large, although it is easy to disassemble, the battery pack will amplify the vibration transmitted to the handle due to the excitation force generated by the ceramic tile tiler during the working process while forcing the ceramic tile to vibrate, which not only makes the user's control comfort low, seriously affects the user's hand feeling, and causes pain and numbness, making it impossible to hold for a long time, and long-term use will cause arm and shoulder strain, and generate a large noise; if the cooperation gap is too small, it is not easy to disassemble. In addition to the ceramic tile tiler, other power tools with battery packs at the handle also have the same cooperation gap dilemma.

[0086] In some embodiments, the output element 32 is an eccentric wheel, and the eccentric wheel is sleeved on at least one end of a motor shaft 311 of the motor 31. In one embodiment, one eccentric wheel is provided, and the eccentric wheel is sleeved on the motor shaft 311 of the motor 31; in another embodiment, the motor 31 is a double-shaft motor, and two eccentric wheels are provided, and the two eccentric wheels are respectively sleeved on the two ends of the motor shaft 311 of the motor 31. It should be noted that the motor shaft 311 drives the eccentric wheel to rotate around a first axis a, and the first axis a is as shown in Figure 8 .
[0087] In some embodiments, as shown in Figure 10 , the distance L2 from the center of gravity of the eccentric wheel to the center of the suction cup 21 is less than or equal to 32 mm.

In some embodiments, the distance L2 from the center of gravity of the eccentric wheel to the center of the suction cup 21 is less than or equal to 20 mm.

[0090] In some embodiments, the motor 31 is a brushless motor. Compared with a brush motor, the brushless motor is more compact, so that the eccentric wheel is closer to the center of the suction cup 21, so that it is easier for the operator to align the point of the output force, thereby facilitating the reduction of the vibration felt by the operator and improving the user's hand feeling. Moreover, the use of a brushless motor facilitates the miniaturization of the tile tiler.
[0091] With continued reference to Figure 8 As shown, the power assembly 30 further comprises a first bearing 33 and a second bearing 34 supported between the second housing 15 and the third housing 16 and sleeved on both ends of the motor shaft 311 to improve the stability and accuracy of the rotation of the motor shaft 311. At least one of the second housing 15 and the third housing 16 is metal, and in this embodiment, the metal is specifically aluminum. The second housing 15 and the third housing 16 can be in direct contact with the stator sheet of the motor 31 or in indirect contact through a heat-conducting element such as a heat-conducting pad or heat-conducting glue to quickly conduct the heat on the motor 31, thereby transferring the heat to the metal housing to quickly dissipate the heat of the motor 31.
[0092] In some embodiments, the second housing 15 and the third housing 16 surround the motor chamber and the output chamber arranged at intervals, the motor 31 is installed in the motor chamber, and the output element 32 is arranged in the output chamber.
[0093] The circuit board assembly 40 is used to control the motor 31. Specifically, the circuit board assembly 40 comprises a printed circuit board and a plurality of power elements and a controller arranged on the printed circuit board, and the controller is configured to output a control signal to the plurality of power elements to control the operation of the motor 31.
[0094] In some embodiments, one printed circuit board is provided, and the controller, the power elements, the display circuit, the speed regulation circuit, and the power supply circuit are integrated on the printed circuit board. In some parallel embodiments, two or more printed circuit boards are provided. Taking two as an example, the printed circuit boards comprise a first printed circuit board and a second printed circuit board, the power elements are arranged on the first printed circuit board, and the controller, the display circuit, the speed regulation circuit, and the power supply circuit are arranged on the second printed circuit board. Of course, in other embodiments, part of the power elements, the controller, the display circuit, the speed regulation circuit, and the power supply circuit are integrated on the first printed circuit board, and the remaining part is integrated on the second printed circuit board; or, more printed circuit boards are added, and the power elements, the controller, the display circuit, the speed regulation circuit, and the power supply circuit are re-divided and integrated on the same or different printed circuit boards. It should be noted that the principle of how the circuit board assembly 40 controls the tile tiler through the power elements, the controller, the display circuit, the speed regulation circuit, and the power supply circuit is prior art, which is not described in detail here. The first printed circuit board and the second printed circuit board can be integrated together or separately provided.
[0095] In one embodiment, the first printed circuit board integrated with the power element is arranged in the handle 11. When the handle 11 comprises a main handle 111 and a sub handle 112, the first printed circuit board can be arranged in the main handle 111 or in the sub handle 112.
[0096] In one embodiment, the first printed circuit board is arranged in the shell main body 13. When the shell main body 13 comprises a main body part 131 and a head shell part 132, the first printed circuit board can be arranged in the head shell part 132 or in the main body part 131.
[0097] In one embodiment, the first printed circuit board integrated with the power element is arranged in the angle of the power combination part 12.
[0098] In one embodiment, when the shell 10 comprises a first shell 14 covering the suction cup 21 and a second shell 15 for mounting the motor 31, the first printed circuit board integrated with the power element can be arranged in the first shell 14 or in the second shell 15.
[0099] In one embodiment, when the shell 10 further comprises a third shell 16 covering the motor 31, the first printed circuit board integrated with the power element is arranged in the third shell 16.
[0100] In some embodiments, the projection of the first printed circuit board integrated with the power element on a first plane at least partially overlaps the projection of the suction cup 21 on the first plane, and the first plane is substantially parallel to the suction cup plane of the suction cup 21. Such arrangement makes the first printed circuit board closer to the brushless motor and the display interface for displaying the parameters related to the brushless motor, so that the position layout of the first printed circuit board is more reasonable. It should be noted that the display interface is generally arranged on the top surface of the tile tiling machine and located opposite to the suction cup 21.
[0101] The battery pack 50 is used at least for powering the circuit board assembly 40 and the power assembly 30. Of course, in addition to the circuit board assembly 40 and the power assembly 30, the battery pack 50 can also be used to power other components in the tile tiling machine that need power. In some embodiments, a plug-in cavity is formed on the power combination part 12, and the battery pack 50 can be inserted into the plug-in cavity to realize plug-in connection with the power combination part 12, i.e. the power combination part 12 allows the battery pack 50 to be detachably plugged in substantially along a first direction. Figure 15
[0102] In some embodiments, the tile tiler further comprises a locking assembly for locking the battery pack 50 in the first direction. In one embodiment, the locking assembly comprises a hook and a slot, one of which is provided on the inner wall surface of the plug-in cavity and the other of which is provided on the outer wall surface of the battery pack 50. During the process of inserting the battery pack 50 into the plug-in cavity in the first direction, the hook can be clamped in the slot, thereby achieving the locking of the battery pack 50 and the power combination part 12 in the first direction.
[0103] In order to facilitate the replacement of the battery pack 50, in some embodiments, continuing to refer to Figure 1 As shown, the first half shell 101 and the second half shell 102 are detachably connected by the locking screw 17. Specifically, one locking screw sleeve 18 is respectively arranged on the part of the first half shell 101 and the second half shell 102 for forming the power combination part 12, and the locking screw 17 is arranged in the two locking screw sleeves 18. When it is necessary to replace the battery pack 50, the locking screw 17 is first screwed to separate the part of the first half shell 101 for forming the power combination part 12 and the part of the second half shell 102 for forming the power combination part 12 by a gap, so as to increase the plug-in cavity, and then the battery pack 50 is detached from the plug-in cavity. Such an arrangement reduces the difficulty of replacing the battery pack 50.
[0104] In one embodiment, the locking screw 17 is an insert screw, and a locking nut and a pressing piece are further arranged at the threaded end of the insert screw.
[0105] In one embodiment, a knob part is further arranged at one end of the locking screw 17, and the user drives the locking screw 17 by rotating the knob part.
[0106] In addition to using the cooperation of the locking screw sleeve 18 and the locking screw 17 to achieve the locking of the battery pack 50, as Figures 15 to 19 shown, the tile tiler can also adjust the fitting gap between the battery pack 50 and the power combination part 12 of the machine shell 10 by the biasing member 90, thereby achieving the locking of the battery pack 50. At least part of the biasing member 90 is connected with the machine shell 10, specifically with the power combination part 12, and the biasing member 90 is used to lock the battery pack 50 in the second direction in the power combination part 12. The second direction is as shown in Figure 15 .
[0107] Combined with Figure 3 and Figure 15The battery pack 50 is provided with an unlocking member 51 connected to a buckle 511 for mounting the battery pack 50 to the power combining portion 12. When the battery pack 50 is combined with the power combining portion 12, the first surface 52 of the battery pack 50 is in contact with the power combining portion 12. When the battery pack 50 is not mounted to the power combining portion 12, the user can insert the battery pack 50 into the power combining portion 12 in the plug-in direction of the battery pack 50. As the battery pack 50 is inserted into the power combining portion 12, the buckle 511 protrudes from the first surface 51 and extends into the power combining portion 12, and the battery pack 50 is combined with the power combining portion 12. The user then operates the biasing member 90 to further lock the battery pack 50 to the power combining portion 12. When it is necessary to detach the battery pack 50 from the power combining portion 12, the biasing member 90 needs to be loosened first, and then the unlocking member 51 is operated. The unlocking member 51 is connected to the buckle 511 provided on the battery pack 50. When the user presses the unlocking member 51, the buckle 511 is retracted to be flush with the first surface 51, so that the battery pack 50 is loosened from the power combining portion 12.
[0108] Specifically, the biasing member 90 includes a clamping member 91 provided on one side of the battery pack 50, an operating member 92 for the user to operate, and an adjusting member. The clamping member 91 is configured to be movable in a second direction and to synchronously drive the battery pack 50 to move in the second direction, so that the side of the battery pack 50 away from the clamping member 91 can be pressed against the power combining portion 12, i.e., the battery pack 50 is clamped between the clamping member 91 and the power combining portion 12. The first direction is substantially perpendicular to the second direction, and such arrangement does not affect the plug-in force of the battery pack 50, so that the user can easily plug in and plug out the battery pack 50 while conveniently adjusting the fitting gap between the battery pack 50 and the power combining portion 12 of the case 10. The operating member 92 can drive the clamping member 91 to switch between a first position for clamping the battery pack 50 and a second position for releasing the battery pack 50, and the operating member 92 is configured to be rotatable about a first straight line. If the operating member 92 is operated in reverse, the clamping member 91 releases the clamping of the battery pack 50 in the second direction. The adjusting member is used to adjust the clamping degree of the clamping member 91 on the battery pack 50.
[0109] It should be noted that the first straight line is as shown by c in Figure 15 In one embodiment, the two ends of the operating member 92 are provided with two oppositely arranged ring portions, and the operating member 92 is rotatably connected to the case 10 through the ring portions. The first straight line is a straight line passing through the centers of the two ring portions.
[0110] In some embodiments, as shown in Figures 15 to 17As shown, the biasing member 90 further comprises a rotating rod 93, a first cam 94 and a second cam 95. The rotating rod 93 is rotatably arranged on the power combination portion 12 of the casing 10, the operating member 92 is connected with the rotating rod 93, the first cam 94 and the second cam 95 are arranged in the power combination portion 12 of the casing 10, the first cam 94 is movably sleeved on the rotating rod 93, and the first cam 94 is fixedly connected with the clamping member 91, the second cam 95 is sleeved on the rotating rod 93 and is fixed in position, and a first curved surface on the first cam 94 and a second curved surface on the second cam 95 slide against each other. By changing the abutting position of the first curved surface and the second curved surface, the first cam 94 and the second cam 95 can be switched to the fully fitted state as shown in FIG. 1B, and can also be switched to the state with the maximum spacing as shown in FIG. 1C. Figure 17 Figure 16
[0111] When the operating member 92 rotates around the first straight line, the rotating rod 93 can be synchronously rotated around the first straight line under the driving of the operating member 92, the rotating rod 93 can drive the second cam 95 to synchronously rotate around the first straight line, the second cam 95 rotating around the first straight line can push the first cam 94 to move in the second direction, and the first cam 94 can drive the clamping member 91 to synchronously move in the second direction, so as to switch the clamping member 91 between the first position for clamping the battery pack 50 and the second position for releasing the battery pack 50. Whether the clamping member 91 moves towards the battery pack 50 to clamp the battery pack 50 or moves away from the battery pack 50 to release the battery pack 50 depends on the rotating direction of the operating member 92. For example, if the operating member 92 rotates counterclockwise, the clamping member 91 moves towards the first position, and if the operating member 92 rotates clockwise, the clamping member 91 moves towards the second position.
[0112] In an embodiment, the clamping member 91 is a Z-shaped folded plate structure, which comprises a first vertical plate, a horizontal plate and a second vertical plate connected in sequence, the first vertical plate is used for fixedly connecting with the first cam 94, and the second vertical plate is used for clamping the battery pack 50.
[0113] In order to realize the fixed connection between the first vertical plate and the first cam 94, a waist-shaped hole is arranged on the first vertical plate, the first cam 94 comprises two oppositely arranged arc-shaped blocks, the two arc-shaped blocks are inserted into the waist-shaped hole and respectively abut against two arc surfaces oppositely arranged on the waist-shaped hole.
[0114] In an embodiment, the operating member 92 is a handle 921. The handle 921 can be an L-shaped handle, a U-shaped handle, a T-shaped handle or the like. The handle 921 has a connecting end, which is used for fixedly connecting with the rotating rod 93.
[0115] In one embodiment, the rotating rod 93 is a bolt. The bolt includes a nut and a stud, and the connecting end of the handle 921 is provided with a hexagonal hole. The nut is hexagonal, and the nut is installed in the hexagonal hole, so as to fix the bolt and the handle 921.
[0116] In one embodiment, the rotating rod 93 is provided with a threaded segment, such as a stud of a bolt. The adjusting member is an adjusting nut 97 which is screwed on the threaded segment of the rotating rod 93. The adjusting nut 97 is in limiting abutment with the second cam 95. By screwing the adjusting nut 97, the pressing force of the second cam 95 on the first cam 94 can be changed. The first cam 94, the second cam 95 and the adjusting nut 97 are installed on the stud of the bolt in sequence. The adjusting nut 97 can rotate and move left and right on the stud of the bolt. The adjusting nut 97 can press the first cam 94 through the second cam 95, so as to adjust the tightness of the clamping member 91 on the battery. In addition, a limiting surface can be provided on the power combination part 12 of the case 10, so as to limit the movement of the second cam 95 on the rotating rod 93. Thus, when the rotating rod 93 is rotated, the second cam 95 only rotates relative to the power combination part 12 of the case 10, and does not move.
[0117] In one embodiment, the biasing member 90 further includes a first reset elastic member 96. The first reset elastic member 96 is sleeved on the rotating rod 93. One end of the first reset elastic member 96 is fixed in the power combination part 12 of the case 10, and the other end is in abutment with the first cam 94. The first reset elastic member 96 has a tendency to reset the clamping member 91 to the second position. The first reset elastic member 96 can be a spiral spring. A limiting groove is formed on the power combination part 12 of the case 10. One end of the spiral spring is placed in the limiting groove and abuts against the groove bottom surface.
[0118] In some parallel embodiments, as shown in Figure 18 and Figure 19 , the power combination part 12 of the case 10 is provided with a slide way in the second direction. The clamping member 91 includes a sliding block 911 and a pressing plate 912 which are connected with each other. The sliding block 911 is slidably placed in the slide way and is circumferentially limited. The pressing plate 912 is arranged opposite to part of the structure of the battery pack 50, and is used to press the battery pack 50. The biasing member 90 further includes a screw rod 98. The screw rod 98 is rotatably arranged on the power combination part 12 of the case 10. The operating member 92 is fixed on one end of the screw rod 98. The other end of the screw rod 98 is in threaded connection with the sliding block 911.
[0119] When the operating member 92 rotates around the first straight line, the screw rod 98 can rotate around the first straight line synchronously under the driving of the operating member 92. Since the sliding block 911 is circumferentially limited, the sliding block 911 cannot rotate. Under the driving of the screw rod 98, the clamping member 91 can move in the second direction, so that the clamping member 91 is switched between the first position for clamping the battery pack 50 and the second position for releasing the battery pack 50. Whether the clamping member 91 moves towards the battery pack 50 to clamp the battery pack 50 or moves away from the battery pack 50 to release the battery pack 50 depends on the rotating direction of the operating member 92. For example, if the operating member 92 rotates counterclockwise, the clamping member 91 moves towards the first position. If the operating member 92 rotates clockwise, the clamping member 91 moves towards the second position.
[0120] In an embodiment, the operating member 92 is a knob 922, and the knob 922 is fixed to one end of the screw rod 98.
[0121] In an embodiment, the screw rod 98 is an insert bolt, the knob 922 is fixed to the large-size end of the insert bolt, and the small-size end of the insert bolt is threadedly connected with the sliding block 911.
[0122] In an embodiment, the biasing member 90 further comprises a second reset elastic member 99, the second reset elastic member 99 is sleeved on the screw rod 98, one end of the second reset elastic member 99 is fixed in the power combination portion 12 of the casing 10, the other end of the second reset elastic member 99 abuts against the sliding block 911, and the second reset elastic member 99 has a tendency to reset the clamping member 91 to the second position. The first reset elastic member 96 can be a coil spring, a limiting groove is formed on the power combination portion 12 of the casing 10, one end of the coil spring is arranged in the limiting groove, and the other end of the coil spring abuts against the bottom surface of the limiting groove.
[0123] It should be noted that in the foregoing embodiments, the biasing member 90 is arranged on the power combination portion 12 of the casing 10. In other embodiments, the biasing member 90 can also be arranged on the battery shell of the battery pack 50. For example, the clamping member 91 is arranged on the battery shell, and the position of the clamping member 91 can be changed by rotating the operating member 92, so that the clamping member 91 can be clamped from the outside on the outer wall surface of the power combination portion 12 of the casing 10 or abut against the inner wall surface of the power combination portion 12 of the casing 10 from the inside, thereby adjusting the fitting gap between the battery pack 50 and the power combination portion 12 of the casing 10.
[0124] In addition, regardless of whether the operating member 92 is arranged as the handle 921 or the knob 922, the operating member 92 has a tensioning position and a releasing position, and a receiving space is formed on the power combination portion 12 of the casing 10, and the operating member 92 in the tensioning position is arranged in the receiving space. In this way, the compactness of the structure can be improved. In an embodiment, the receiving space is a receiving groove; in another embodiment, the receiving space is a receiving hole.
[0125] Further, the operation member 92 is connected with a locking device for locking the operation member 92 in the tension position or the release position. In an embodiment, the locking device can be a binding belt arranged at the opening of the accommodating space, a magnetic member, a limiting elastic protrusion, etc. For example, if the handle 921 enters the accommodating space, the handle 921 can be bound by the binding belt, or the handle 921 enters the accommodating space by extruding the limiting elastic protrusion, and then the limiting elastic protrusion is used for limiting to avoid accidental disengagement from the accommodating space, or a magnet member is arranged on the knob 922, and after the knob 922 enters the accommodating space, the knob 922 is locked by the adsorption of the magnetic member and the magnet member.
[0126] In some embodiments, the projection of the center of gravity of the tile tiling machine after the battery pack 50 is installed in the first plane does not overlap with the projection of the suction cup 21 in the first plane. Such an arrangement makes the center of gravity of the tile tiling machine more reasonable, and the operator feels comfortable when holding the tile tiling machine for tiling, especially when the operator works for a long time, which is beneficial to reduce the labor intensity of the operator.
[0127] In some parallel embodiments, the center of gravity of the tile tiling machine after the battery pack 50 is installed is on the handle 11. Such an arrangement enables the tile tiling machine to be placed in a manner that the battery pack 50 is tilted and abuts to the placement surface, which not only has good stability, but also facilitates the operator to hold the handle 11 again to lift the tile tiling machine for work.
[0128] In some parallel embodiments, the center of gravity of the tile tiling machine without the battery pack 50 is on the handle 11. Such an arrangement facilitates the user to place the tile tiling machine without the battery pack 50 in a manner that the handle 11 is tilted and abuts to the placement surface when the user replaces the battery pack 50, which not only has good stability, but also facilitates the operator to hold the handle 11 again to lift the tile tiling machine to assemble the battery pack 50.
[0129] In some embodiments, continuing to refer to Figure 2 As shown in the figure, the plug-in direction of the battery pack 50 forms an angle β with the second plane, wherein β is less than or equal to 153°, and the second plane is parallel to the first plane. It should be noted that the larger the angle β, the less likely the elbow of the user to touch the battery pack during operation. However, considering the length of the grip below the handle 11 to ensure the length of the handle-man machine grip, 153° is close to the maximum value. In an embodiment, β is 153°; in an embodiment, β is 150°; in an embodiment, β is 140°; in an embodiment, β is 130°; in an embodiment, β is 120°.

[0139] In some embodiments, the at least one user input device includes a first user input device 60 provided on the auxiliary handle 112. The first user input device 60 is provided on the back or side of the auxiliary handle 112 according to the needs, where the side can be the front side, the left side or the right side, and of course, in other embodiments, the first user input device 60 can also be provided on the top of the auxiliary handle 112 or at the connection between the auxiliary handle 112 and the shell body 13, as long as it is located at a position convenient for the user to operate.
[0140] In some embodiments, as shown in Figure 7 the at least one user input device includes a second user input device 70 provided on the shell body 13.
[0141] In some parallel embodiments, two user input devices are provided, which are the first user input device 60 and the second user input device 70, and the first user input device 60 or the second user input device 70 is configured to be able to start the motor 31. By increasing one user input device, the operator can provide a more optimal human-machine operation experience when the operator holds the tile tiling machine with both hands, so as to achieve the purpose of optimizing the use experience of the operator.
[0142] In some embodiments, the first user input device 60 and the second user input device 70 are simultaneously triggered to start the motor 31. In some parallel embodiments, the first user input device 60 or the second user input device 70 is triggered alone to start the motor 31.
[0143] In order to improve the intelligent start of the tile tiler, in an embodiment, the first user input device 60 is triggered alone to make the motor 31 rotate at a first rotating speed, the second user input device 70 is triggered alone to make the motor 31 rotate at a second rotating speed, and the first user input device 60 and the second user input device 70 are triggered simultaneously to make the motor 31 rotate at a third rotating speed, wherein the first rotating speed, the second rotating speed and the third rotating speed are different.
[0144] In an embodiment, the first rotating speed, the second rotating speed and the third rotating speed correspond to three speed gears of the tile tiler respectively. In a specific embodiment, the first rotating speed, the second rotating speed and the third rotating speed are sequentially increased, and correspondingly, the three speed gears are a first speed gear, a second speed gear and a third speed gear respectively.
[0145] In order to improve the speed regulation range of the tile tiler, continuing to refer to Figure 7 It is shown that the speed regulation button 71 for regulating the output rotating speed of the motor 31 is further arranged on the shell body 13. Of course, the speed gears of the tile tiler can be arranged to be more than three, for example, four, five or more, and in addition to the first speed gear, the second speed gear and the third speed gear corresponding to the first rotating speed, the second rotating speed and the third rotating speed respectively, the other speed gears can be arranged between the three speed gears or higher or lower than the three speed gears. When the tile tiler is started at the first speed gear, the second speed gear or the third speed gear, the tile tiler can be switched to other speed gears by triggering the speed regulation button 71.
[0146] In an embodiment, the speed regulation button 71 is an acceleration button; in an embodiment, the speed regulation button 71 is a deceleration button; and in an embodiment, two speed regulation buttons 71 are arranged, and the two speed regulation buttons 71 are an acceleration button and a deceleration button respectively.
[0147] Continuing to refer to Figure 7 It is shown that the gear position indicating lamp 72 for indicating the gear position of the output rotating speed of the motor 31 is further arranged on the shell body 13. The number of the gear position indicating lamps 72 is equal to the number of the speed gears, and is arranged one by one in correspondence, and the plurality of gear position indicating lamps 72 are arranged in sequence or marked with symbols, and the speed gear of the tile tiler is prompted by lighting a certain gear position indicating lamp 72.
[0148] In some embodiments, the speed regulation button 71 and the gear position indicating lamp 72 are arranged on the top surface of the head shell part 132, so that the speed regulation button 71, the gear position indicating lamp 72 and the head shell part 132 jointly constitute the human-machine interaction structure of the tile tiler and the operator.
[0149] In some embodiments, the tile tiler further comprises a pressure sensor, and the operator adjusts the output rotation speed of the motor 31 by adjusting the pressure applied to the pressure sensor. For example, a pressure sensing area is formed on the casing 10, and the pressure sensor is arranged on the pressure sensing area. When the user increases the pressure applied to the pressure sensing area, the pressure sensor receives an increased pressure, and the circuit board assembly 40 obtains the increased pressure signal and controls the motor 31 to increase its output rotation speed. Conversely, when the user decreases the pressure applied to the pressure sensing area, the pressure sensor receives a decreased pressure, and the circuit board assembly 40 obtains the decreased pressure signal and controls the motor 31 to decrease its output rotation speed. When the operator does not press the pressure sensing area, the motor 31 stops. Of course, in order to ensure the safety of starting, a common pressing force of between 1 kgf and 10 kgf can be added as a starting protection value. Since the operator needs to press the tile tiler when laying tiles, the motor 31 is started only after the pressing force exceeds the starting protection value during the first half of the pressing process, and the motor 31 is stopped when the pressing is stopped.
[0150] In some embodiments, the tile tiler further comprises an orientation sensor and a prompting mechanism. The orientation of the tile tiler can be obtained by the orientation sensor, and the prompting mechanism reminds the operator whether the tile tiler has reached the target orientation. When the circuit board assembly 40 obtains that the tile tiler has reached the target orientation, the motor 31 can be automatically stopped. It should be noted that, in the process of pressing and laying tiles, according to the laying position of the tiles, when the tiles are in a completely horizontal or completely vertical state, i.e., the angle of the tiles is 0° or 90°, it indicates that the tiles have been laid in place, and at this time the motor 31 can be stopped, so that the power assembly 30 does not have to generate a vibration source.
[0151] As Figures 11 to 14As shown, the damping assembly 80 is used to reduce the adverse effects of the vibration source generated by the power assembly 30 on the user's hand feeling, specifically, the damping assembly 80 includes a moving seat 81, a support seat 82, a damping spring 83, a guide rod 84, a linear bearing 85, a first connecting piece 86, a second connecting piece 87 and a pre-tightening cap 88. Among them, the support seat 82 is fixed on the first shell 14, the support seat 82 includes a support table 821 and a support column 822, the support table 821 and the support column 821 can be an integral structure, or can be a split structure, the support table 821 is detachably connected to the first shell 14 by screws, the support column 821 is protruded above the support table 821 and extends along the up-down direction of the tile laying machine, the damping spring 83 is sleeved on the support column 821, and the top end of the support column 821 is connected with the pre-tightening cap 88 through the first connecting piece 86, the moving seat 81 is fixed in the shell body 13, the moving seat 81 is connected with the guide rod 84 through the second connecting piece 87, the linear bearing 85 is fixed in the support seat 82, the guide rod 84 is slidingly connected in the linear bearing 85, and the first connecting piece 86 and the second connecting piece 87 can be selected by screws.
[0152] When the motor 31 drives the eccentric wheel to swing, the lower shell with the suction cup assembly 20 swings along the up-down direction. Since the upper shell and the lower shell are separated, the guide rod 84 and the linear bearing 85 of the damping assembly 80 are slidingly connected, and the use of the damping spring 83 can consume excess vibration, so that the vibration transmitted from the lower shell to the upper shell through the damping assembly 80 can be reduced, thereby reducing the adverse effects of the vibration source generated by the power assembly 30 on the user's hand feeling. Moreover, the damping spring 83 is added between the power source combination part 12 and the support seat 82, which can realize the relative positioning of the parts in the vertical direction and the transmission and buffering of force and vibration. The operating force applied by the user on the handle 11, i.e. the downward pressure on the handle 11, is not directly transmitted to the support seat 82, but indirectly transmitted to the support seat 82 and the suction cup 21 through the damping spring 83, and the peak value of the excitation force transmitted in the opposite direction on the suction cup 21 and the support seat 82 will be absorbed by the damping spring 83, thereby reducing the vibration feeling on the handle 11.
[0153] In some embodiments, the guide rod 84 and the linear bearing 85 are provided in multiple groups to improve the accuracy of the movement of the upper shell relative to the lower shell. In one embodiment, the guide rod 84 and the linear bearing 85 are provided in two groups and are respectively arranged on the front and rear sides of the tile laying machine. The moving seat 81 and the support seat 82 are slidingly connected through the linear bearing 85 and the guide rod 84, and are limited to be separated by the pre-tightening cap 88 and the first connecting piece 86, the moving seat 81, the power source combination part 12 and the handle 11 are relatively fixed, and finally the handle 11 is movable up and down relative to the support seat 82. The guide rod 84 and the linear bearing 85 allow the handle 11 and the support seat 82 to relatively slide in the vertical direction, cooperate with the deformation of the damping spring 83; while limiting the handle 11 from swinging greatly relative to the support seat 82 in the vertical direction.
[0154] In some embodiments, the tile tiler further comprises a shock absorbing pad arranged on the support base 82 and horizontally arranged to reduce vibration in the horizontal direction. The shock absorbing pad is an elastic ring, and the number of elastic rings is four, and the four elastic rings are arranged on the left and right sides of the support base 82 respectively. In one embodiment, the shock absorbing pad is a silica gel ring or a rubber ring. Of course, other structures capable of reducing vibration are also applicable to the tile tiler of the present application. For example, a buffer silica gel pad is added between the main handle 111 and the shell main body 13.
[0155] The tile tiler further comprises a vibration isolation cap 89 arranged between the pre-tightening cap 88 and the moving base 81, and a rubber pad 810 arranged between the moving base 81 and the shell main body 13 of the casing 10, and the vibration isolation cap 89 and the rubber pad 810 are used to achieve flexible isolation. The rubber pad 810 functions to isolate the shell main body 13 and the moving base 81, and the vibration isolation cap 89 functions to isolate the moving base 81 and the support base 82, so as to prevent rigid parts from directly transmitting vibration, thereby avoiding the phenomenon of increased amplitude due to rigid collision with each other.
[0156] It should be emphasized that during the operation of the tile tiler by the user holding the handle 11, the transmission path of the pressure applied by the user to the tile tiler is as follows: handle 11→rubber pad 810→moving base 81→shock absorbing spring 83→support base 82→sucker 21→tile. The excitation force generated by the motor 31 driving the eccentric wheel acting on the tile, and the transmission path of the counter-vibration force on the tile to the handle 11 is just the opposite, and is as follows: tile→sucker 21→support base 82→shock absorbing spring 83→moving base 81→rubber pad 810→handle 11.
[0157] In summary, the use of the shock absorbing assembly 80 has the following advantages:
[0158] 1. The user's downward pressure is not directly transmitted to the support base 82, but is transmitted to the support base 82, the sucker 21 and the tile in turn through the handle 11, the rubber pad 810, the shock absorbing spring 83, etc. The vibration of the tile and the support base 82 is transmitted in the opposite direction and then transmitted to the handle 11 after being damped by the shock absorbing spring 83, so as to reduce the amplitude at the handle 11 and change the frequency. The vibration at the support base 82, the sucker 21 and the tile, etc. and the vibration sensation on the handle 11 do not correspond, and through the cooperation of the rigidity coefficient of the shock absorbing spring 83 and the user's common downward pressure, the vibration sensation on the handle 11 can be greatly reduced, and the vibration isolation cap 89 can also prevent the mutual collision, sound, transmission and expansion of vibration when the rigid elements are in contact under no load.
[0159] 2. The guide rod 84 and the linear bearing 85 allow the housing body 13 and the support seat 82 to slide relative to each other in the vertical direction. With the deformation of the shock-absorbing spring 83, the handle 11 can be limited to swinging significantly in the vertical direction relative to the support seat 82.
[0160] 3. Because the handle 11, support base 82, suction cup 21, etc., are elastically connected, the overall vibration mass of the tile paving machine no longer includes the large mass generated by the human body, and the excitation force generated by the eccentric wheel can act more on the tiles. Under the same excitation force, the vibration on the tiles can reach about 2 to 3 times that of existing technologies, which greatly improves work efficiency.
[0161] The average output power of the tile paving machine is greater than or equal to 60W and less than or equal to 200W. In one embodiment, the average output power of the tile paving machine is 60W; in another embodiment, it is 70W; in yet another embodiment, it is 80W; in one embodiment, it is 90W; in one embodiment, it is 100W; in one embodiment, it is 110W; and in one embodiment, it is 120W.
[0162] In the embodiments of this application, in order to make the tile paving machine compact and lightweight, structures specifically for heat dissipation, such as fans, are generally not installed inside the tile paving machine. In some embodiments, the tile paving machine relies on the natural heat dissipation of the casing 10. To improve the heat dissipation performance of the tile paving machine, heat dissipation structures such as heat dissipation holes and heat dissipation fins can be provided on the casing 10, and heat dissipation structures such as heat dissipation holes and heat dissipation fins can also be provided on the second casing 15 and / or the third casing 16 to improve the heat dissipation effect on the motor 31 and the circuit board assembly 40.

Those skilled in the art should understand that the above embodiments do not limit this application in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this application.
