Description

Technical Field

[0001] The present application relates to an electric tool, in particular to a tile paving machine. Background Art

[0002] One of the electric tools in the related art is a tile paving machine, which can use suction cups to absorb tiles and then move them to the laying position. After the tiles are moved to the laying position, the tile paving machine causes the tiles to vibrate at a high frequency to expel the air under the tiles and lay the cement flat, thereby completing the paving of the tiles and reducing the hollowing rate. Compared with the traditional manual paving method of tapping the tiles with a rubber hammer, laying tiles with a tile paving machine is not only efficient, time-saving and labor-saving, but also highly stable and has a high laying flatness.

[0003] In order to improve the stability of the user's operation, the existing tile paving machine is often provided with two handles, a main handle and an auxiliary handle. The user holds the main handle with one hand and the auxiliary handle with the other hand, and the two hands cooperate to operate the tile paving machine. The existing tile paving machine generally sets the button for controlling the start and stop of the motor on or near the handle, so that the start and stop control of the motor is single, and because the hand holding the main handle is generally the user's dominant hand, the dominant hand needs to perform other operations in addition to starting and stopping the motor, which makes the user's dominant hand busy and prone to errors.

[0056] The upper shell body also includes a shell body 13, and the shell body 13 is connected to or integrally formed with the handle 11. In one embodiment, the shell body 13 is located between the main handle 111 and the auxiliary handle 112. An installation cavity is formed in the shell body 13, and the installation cavity has a downward opening. The shock absorbing assembly 80 is installed in the installation cavity and extends downward from the opening. In one embodiment, the shell body 13 includes a main body 131 and a head shell 132, and the main body 131 forms an opening at its lower end and a mounting opening at its top end, and the head shell 132 is connected to the mounting opening. In one embodiment, the head shell 132 is detachably connected to the main body 131, and the detachable connection method includes but is not limited to snap-on, buckle-on, magnetic attraction, etc.

[0057] The upper shell can be an integrally formed part or a split structure. In order to facilitate assembly, in the embodiment of the present application, the upper shell is selected to adopt a split structure. Figure 3 As shown, in the front and rear direction of the tile tiling machine, the upper shell includes a first half shell 101 and a second half shell 102 arranged front and rear, the first half shell 101 and the second half shell 102 are spliced ​​to form the upper shell, and the first half shell 101 and the second half shell 102 both include a part of the handle 11 and the shell body 13.

[0058] The lower shell of the housing 10 further includes a first shell 14, a second shell 15 and a third shell 16. The first shell 14 is mainly used to install the suction cup assembly 20, and the second shell 15 and the third shell 16 are used to install the power assembly 30. In one embodiment, in the up and down direction of the tile tiling machine, the third shell 16 is located above the second shell 15, and the third shell 16 and the second shell 15 are detachably connected, and the detachable connection method includes but is not limited to screw connection, card connection, plug-in connection, etc. In one embodiment, the first shell 14 and the second shell 15 are integrally formed.

[0059] The suction cup assembly 20 includes a suction cup 21 for adsorbing tiles, and the first shell 14 covers the suction cup 21. The suction cup 21 can be adsorbed on the tile by generating negative pressure through deformation. In one embodiment, the bottom surface of the first shell 14 is an annular surface, and the edge of the top surface of the suction cup 21 abuts against the bottom surface of the first shell 14 to ensure the strength of the suction cup 21 to adsorb the tile and avoid the accidental drop of the tile.

[0060] In some embodiments, the diameter of the suction cup 21 is 100 mm-180 mm. In one embodiment, the diameter of the suction cup 21 is 100 mm; in one embodiment, the diameter of the suction cup 21 is 110 mm; in one embodiment, the diameter of the suction cup 21 is 120 mm; in one embodiment, the diameter of the suction cup 21 is 130 mm; in one embodiment, the diameter of the suction cup 21 is 140 mm; in one embodiment, the diameter of the suction cup 21 is 150 mm; in one embodiment, the diameter of the suction cup 21 is 160 mm; in one embodiment, the diameter of the suction cup 21 is 170 mm; in one embodiment, the diameter of the suction cup 21 is 180 mm.

[0061] In some parallel embodiments, the diameter of the suction cup 21 is 120 mm-160 mm. In one embodiment, the diameter of the suction cup 21 is 100 mm; in one embodiment, the diameter of the suction cup 21 is 110 mm; in one embodiment, the diameter of the suction cup 21 is 120 mm; in one embodiment, the diameter of the suction cup 21 is 130 mm; in one embodiment, the diameter of the suction cup 21 is 140 mm; in one embodiment, the diameter of the suction cup 21 is 150 mm; in one embodiment, the diameter of the suction cup 21 is 160 mm.

[0063] In order to facilitate the operator's action so that the suction cup 21 is deformed, continue to refer to Figure 2 As shown, the suction cup assembly 20 also includes a locking handle 22, a connecting seat 23, a connecting rod 24, an elastic member 25 and a connecting plate 26. An installation cavity is formed in the suction cup 21, and the installation cavity includes a first cavity and a second cavity connected in the up and down directions. The size of the first cavity is smaller than the size of the second cavity, so that the installation cavity is stepped. The connecting plate 26 enters the second cavity through the first cavity and is limited in the second cavity. The connecting rod 24 is extended in the up and down directions. The bottom end of the connecting rod 24 is connected to the center of the connecting plate 26. The connecting rod 24 passes through the second cavity and extends to the outside of the suction cup 21. The top end of the connecting rod 24 is rotatably connected to one end of the locking handle 22 through the connecting seat 23, and the other end of the locking handle 22 forms a gripping portion.

[0064] The locking handle 22 has an initial position and a locking position. In one embodiment, the locking handle 22 is located below the main handle 111. The locking handle 11 is switched between the initial position and the locking position by rotating the locking handle 11. Figure 4 As shown, compared with the initial position ( Figure 4 The locking handle 11 (in the middle dotted line position) is in the locking position ( Figure 4 The locking handle 11 in the solid line position is closer to the main handle 111, and the elastic member 25 makes the locking handle 11 tend to rotate toward the initial position.

[0065] In some embodiments, the elastic member 25 is a coil spring, which is sleeved on the connecting rod 24, with one end of the coil spring abutting against the suction cup 21 and the other end abutting against the installation cavity. In one embodiment, the coil spring is conical, with the large end of the coil spring abutting against the suction cup 21 and the small end of the coil spring abutting against the installation cavity.

[0066] In some embodiments, finger grooves are formed on the gripping portion of the locking handle 22 for easy gripping by the operator. The number of finger grooves can be set to one or more according to needs. When the user holds the main handle 111 with one hand, since the locking handle 22 and the main handle 111 are close to each other, the user's fingers can simultaneously hold the locking handle 22 and drive the locking handle 22 to rotate.

[0067] In some embodiments, Figure 5 As shown, a mounting groove 221 is formed on the connecting portion of the locking handle 22, the connecting seat 23 is placed in the mounting groove 221, a rotating shaft groove 231 is formed on the connecting seat 23, a rotating shaft rod 241 is protruded on the connecting rod 24, the top end of the connecting rod 24 is passed through the connecting seat 23, and the rotating shaft rod 241 is rotatably connected in the rotating shaft groove 231, so that the locking handle 22 and the connecting rod 24 are rotatably connected.

[0068] In order to keep the locking handle 22 in the locked position, the operator does not have to hold the locking handle 22 all the time to apply force to the locking handle 22. Figure 6 As shown, the suction cup assembly 20 also includes a locking knob 27 and a locking seat 28. The locking seat 28 is fixed on the top surface of the first shell 14. A threaded hole is penetrated through the locking seat 28. The locking knob 27 is rotatably threaded in the threaded hole. By rotating the locking knob 27, the locking knob 27 can be moved toward or away from the locking handle 22. When part of the structure of the locking knob 27 moves to the bottom of the locking handle 22, it can support the locking handle 22 from bottom to top. When the locking knob 27 is completely moved to the side of the locking handle 22, the locking handle 22 is no longer limited by the locking knob 27, so that the locking handle 22 can be reset to the initial position.

[0069] The power assembly 30 is used to generate a vibration source. By transmitting the vibration to the tiles, the air under the tiles can be discharged and the cement used to stick the tiles can be vibrated flat, thereby reducing the hollow rate of the tiles. Figures 8 to 10 As shown, the power assembly 30 includes a motor 31 and an output element 32 driven by the motor 31.

[0071] In some parallel embodiments, the effective stack length L1 of the stator of the motor 31 is less than or equal to 15 mm.

[0072] In some embodiments, the output element 32 is an eccentric wheel, and the eccentric wheel is sleeved on at least one end of the motor shaft 311 of the motor 31. In one embodiment, there is one eccentric wheel, and the eccentric wheel is sleeved on the motor shaft 311 of the motor 31; in another embodiment, the motor 31 is a dual-axis motor, and there are two eccentric wheels, and the two eccentric wheels are sleeved on both 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 the first axis a, and the first axis a is as shown in FIG. Figure 8 as shown in .

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 28 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 25 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.

[0074] In a specific embodiment, the distance L2 from the center of gravity of the eccentric wheel to the center of the suction cup 21 is 32 mm; in a specific embodiment, the distance L2 from the center of gravity of the eccentric wheel to the center of the suction cup 21 is 30 mm; in a specific embodiment, the distance L2 from the center of gravity of the eccentric wheel to the center of the suction cup 21 is 28 mm; in a specific embodiment, the distance L2 from the center of gravity of the eccentric wheel to the center of the suction cup 21 is 25 mm; in a specific embodiment, the distance L2 from the center of gravity of the eccentric wheel to the center of the suction cup 21 is 20 mm; in a specific embodiment, the distance L2 from the center of gravity of the eccentric wheel to the center of the suction cup 21 is 19 mm.

[0079] The circuit board assembly 40 is used to control the motor 31 . Specifically, the circuit board assembly 40 includes a printed circuit board and a plurality of power components and a controller arranged on the printed circuit board. The controller is configured to output control signals to the plurality of power components to control the operation of the motor 31 .

[0080] In some embodiments, a printed circuit board is provided with one, and a controller, a power element, a display circuit, a speed regulating circuit and a 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 board includes a first printed circuit board and a second printed circuit board, the first printed circuit board is arranged with a power element, and the second printed circuit board is arranged with a controller, a display circuit, a speed regulating circuit and a power supply circuit. Of course, in other embodiments, part of the power element, the controller, the display circuit, the speed regulating 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 element, the controller, the display circuit, the speed regulating 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 realizes the control of the tile paving machine through the power element, the controller, the display circuit, the speed regulating circuit and the power supply circuit is a prior art and will not be described in detail here. The first printed circuit board and the second printed circuit board can be integrated together or separately arranged.

[0081] In one embodiment, a first printed circuit board with integrated power components is disposed in the handle 11 . When the handle 11 includes a main handle 111 and a sub-handle 112 , the first printed circuit board can be disposed in the main handle 111 or in the sub-handle 112 .

[0082] In one embodiment, the first printed circuit board is disposed in the shell body 13 . When the shell body 13 includes a main body portion 131 and a head shell portion 132 , the first printed circuit board can be disposed in the head shell portion 132 or in the main body portion 131 .

[0083] In one embodiment, the first printed circuit board with integrated power components is disposed within the extension angle of the power combining portion 12 .

[0084] In one embodiment, when the housing 10 includes 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 power components can be disposed in the first shell 14 or in the second shell 15 .

[0085] In one embodiment, when the housing 10 further includes a third shell 16 covering the motor 31 , the first printed circuit board integrated with power components is disposed in the third shell 16 .

[0086] In some embodiments, the projection of the first printed circuit board with integrated power components on the first plane overlaps at least partially with the projection of the suction cup 21 in the first plane, and the first plane is substantially parallel to the suction cup plane of the suction cup 21. This arrangement makes the first printed circuit board closer to the brushless motor and the display interface for displaying the brushless motor related parameters, making the position layout of the first printed circuit board more reasonable. It should be noted that the display interface is generally arranged on the top surface of the tile paving machine and is located directly opposite to the suction cup 21.

[0087] The battery pack 50 is used to at least supply power to 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 supply power to other components in the tile tiling machine that require electricity. In some embodiments, a plug-in cavity is formed on the power supply combination 12, and the battery pack 50 can be inserted into the plug-in cavity to achieve plug-in connection with the power supply combination 12.

[0088] In order to facilitate replacement of the battery pack 50, in some embodiments, continue to refer to Figure 1 As shown, the first half shell 101 and the second half shell 102 are detachably connected by a locking screw 17. Specifically, a locking screw 18 is provided on the first half shell 101 and the second half shell 102 for forming the power supply combination 12, respectively, and the locking screw 17 is inserted into the two locking screws 18. When the battery pack 50 needs to be replaced, the locking screw 17 is first screwed to form a gap between the part of the first half shell 101 for forming the power supply combination 12 and the part of the second half shell 102 for forming the power supply combination 12, so as to increase the plug-in cavity, and then the battery pack 50 is removed from the plug-in cavity. Such a configuration reduces the difficulty of replacing the battery pack 50.

[0089] In some embodiments, the projection of the center of gravity of the tile paving 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. This arrangement makes the center of gravity position of the tile paving machine more reasonable, and the operator feels comfortable when holding the tile paving machine to lay tiles, which is helpful to reduce the labor intensity of the operator, especially when the operator works for a long time.

[0090] In some parallel embodiments, the center of gravity of the tile paving machine after the battery pack 50 is installed is on the handle 11. Such an arrangement enables the tile paving machine to be placed in a manner that the battery pack 50 is tilted against the placement surface, which not only has good stability, but also facilitates the operator to hold the handle 11 again to lift the tile paving machine for operation.

[0091] In some parallel embodiments, the center of gravity of the tile paving machine when the battery pack 50 is not installed is on the handle 11. Such a configuration makes it convenient for the user to replace the battery pack 50 by placing the tile paving machine without the battery pack 50 in a manner that the handle 11 is tilted against the placement surface, which not only has good stability, but also facilitates the operator to hold the handle 11 again to lift the tile paving machine to assemble the battery pack 50.

[0092] In some embodiments, continue to refer to Figure 2 As shown, the plugging and unplugging 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 is, the less likely the user's elbow will touch the battery pack during operation. However, considering the grip length under the handle 11 (to ensure the human-machine grip length basis of the handle), about 153° is close to the maximum value. In one embodiment, β is 153°; in one embodiment, β is 150°; in one embodiment, β is 140°; in one embodiment, β is 130°; in one embodiment, β is 120°.

[0093] In some embodiments, the weight of the battery pack 50 is greater than or equal to 200 g and less than or equal to 450 g. In one embodiment, the weight of the battery pack 50 is 350 g; in one embodiment, the weight of the battery pack 50 is 390 g; in one embodiment, the weight of the battery pack 50 is 420 g; in one embodiment, the weight of the battery pack 50 is 450 g.

[0096] In some embodiments, the total power of the battery pack 50 is greater than or equal to 1.5 Ah and less than or equal to 3.5 Ah.

[0097] In some embodiments, the total power of the battery pack 50 is less than or equal to 2.5A·h. In one embodiment, the total power of the battery pack 50 is 2.5A·h; in one embodiment, the total power of the battery pack 50 is 2A·h; in one embodiment, the total power of the battery pack 50 is 1.8A·h; in one embodiment, the total power of the battery pack 50 is 1.5A·h.

[0098] In some embodiments, the total power of the battery pack 50 is greater than or equal to 2A·h and less than or equal to 2.5A·h.

[0099] In some embodiments, the energy of the battery pack 50 is less than or equal to 50Wh.

[0101] The user input device is used for the operator to start or stop the motor 31. In some embodiments, when the hand is held on the auxiliary handle 112, the user input device can be touched by the operator's finger held on the auxiliary handle 112 to start or stop the motor 31. The user input device can be set to one or more according to needs.

[0102] In some embodiments, at least one user input device includes a first user input device 60, and the first user input device 60 is disposed on the auxiliary handle 112. The first user input device 60 is disposed on the back or side of the auxiliary handle 112 as required, and the side here may be the front side, the left side, or the right side. Of course, in other embodiments, the first user input device 60 may also be disposed on the top surface 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 that is convenient for the user to operate.

[0103] In some embodiments, Figure 7As shown, the at least one user input device includes a second user input device 70 , and the second user input device 70 is disposed on the shell body 13 .

[0104] In some parallel embodiments, two user input devices are provided, namely, a first user input device 60 and a second user input device 70, and the first user input device 60 or the second user input device 70 is configured to start the motor 31. By adding a user input device, the operator can be provided with a better human-machine operation experience when holding the tile paving machine with both hands, thereby achieving the purpose of optimizing the operator's use experience.

[0105] In some embodiments, the motor 31 can be started only when the first user input device 60 and the second user input device 70 are triggered simultaneously. In some parallel embodiments, the motor 31 can be started only when the first user input device 60 or the second user input device 70 is triggered alone.

[0106] In order to improve the startup intelligence of the tile tiling machine, in one embodiment, the first user input device 60 is triggered alone to cause the motor 31 to rotate at a first speed, the second user input device 70 is triggered alone to cause the motor 31 to rotate at a second speed, and the first user input device 60 and the second user input device 70 are triggered simultaneously to cause the motor 31 to rotate at a third speed, wherein the first speed, the second speed and the third speed are different.

[0107] In one embodiment, the first speed, the second speed and the third speed correspond to three speed gears of the tile paving machine. In a specific embodiment, the first speed, the second speed and the third speed increase in sequence, and correspondingly, the three speed gears are the first speed gear, the second speed gear and the third speed gear.

[0108] In order to improve the speed range of the tile paving machine, continue to refer to Figure 7 As shown, a speed regulating button 71 for adjusting the output speed of the motor 31 is also provided on the shell body 13. Of course, the speed gears of the tile paving machine can be set to more than three, such as four, five or more. In addition to the first speed gear, the second speed gear and the third speed gear corresponding to the first speed, the second speed and the third speed, respectively, other speed gears can be located between these three speed gears, and can also be higher or lower than these three speed gears. When the tile paving machine is started at the first speed gear, the second speed gear or the third speed gear, the tile paving machine can be switched to other speed gears by triggering the speed regulating button 71.

[0109] In one embodiment, the speed adjustment button 71 is an acceleration button; in one embodiment, the speed adjustment button 71 is a deceleration button; in one embodiment, two speed adjustment buttons 71 are provided, and the two speed adjustment buttons 71 are an acceleration button and a deceleration button respectively.

[0110] Continue to refer to Figure 7 As shown, the housing body 13 is also provided with a gear indicator light 72 for indicating the gear position of the output speed of the motor 31. The number of the gear indicator lights 72 is equal to the number of speed gears, and they are arranged one by one. The multiple gear indicator lights 72 are arranged in sequence or marked with symbols, and the speed gear position of the tile paving machine is indicated by lighting a certain gear indicator light 72.

[0111] In some embodiments, the speed control button 71 and the gear indicator light 72 are both arranged on the top surface of the head shell 132, so that the speed control button 71, the gear indicator light 72 and the head shell 132 together constitute a human-computer interaction structure for the tile tiling machine to interact with the operator.

[0112] In some embodiments, the tile paving machine further includes a pressure sensor, and the operator adjusts the pressure applied to the pressure sensor to adjust the output speed of the motor 31. For example, a pressure sensing area is formed on the housing 10, and the pressure sensor is arranged in the pressure sensing area. When the pressure applied by the user to the pressure sensing area increases, the pressure on the pressure sensor increases. After the circuit board assembly 40 obtains the pressure increase signal, it controls the motor 31 to increase its output speed. On the contrary, when the pressure applied by the user to the pressure sensing area decreases, the pressure on the pressure sensor decreases. After the circuit board assembly 40 obtains the pressure decrease signal, it controls the motor 31 to reduce its output 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 between 1kgf-10kgf can be added as a starting protection value. Since the operator needs to press the tile paving machine when laying tiles, the motor 31 is started after the pressing force exceeds the starting protection value in the first half of the pressing process. When the pressing stops, the motor 31 is turned off.

[0113] In some embodiments, the tile paving machine also includes an orientation sensor and a prompt mechanism. The orientation sensor can obtain the position of the tile paving machine, and the prompt mechanism can remind the operator whether the tile paving machine has reached the target position. When the circuit board assembly 40 obtains that the tile paving machine has reached the target position, the motor 31 can be controlled to automatically stop. It should be noted that in the process of applying pressure to pave the tiles, according to the laying position of the tiles, when the tiles are in a completely horizontal or completely vertical state, that is, the angle of the tiles is 0° or 90°, it indicates that the tiles have been laid in place. At this time, the motor 31 can be stopped, so that the power assembly 30 does not need to generate a vibration source.

[0114] like Figures 11 to 14 As shown, the shock absorbing assembly 80 is used to reduce the adverse effect of the vibration source generated by the power assembly 30 on the user's hand feeling. Specifically, the shock absorbing assembly 80 includes a moving seat 81, a support seat 82, a shock absorbing 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, and the support seat 82 includes a support platform and a support column. The support platform and the support column can be an integrally formed structure or a split structure. The support platform is detachably connected to the first shell 14 by screws, and the support column is convexly arranged above the support platform and extends along the vertical direction of the tile paving machine. The top of the support column is connected to the pre-tightening cap 88 through the first connecting piece 86. The moving seat 81 is fixed in the shell body 13, and the moving seat 81 is connected to the guide rod 84 through the second connecting piece 87. The linear bearing 85 is fixed in the support seat 82, and the guide rod 84 is slidably connected in the linear bearing 85. The first connecting piece 86 and the second connecting piece 87 can both be screws.

[0115] When the motor 31 drives the eccentric wheel to swing, the lower shell swings with the suction cup assembly 20 in the up and down directions. Since the upper shell and the lower shell are separated, the guide rod 84 and the linear bearing 85 of the shock absorbing assembly 80 are slidably connected, and the use of the shock absorbing spring 83 can consume excess vibration, so that the vibration transmitted from the lower shell to the upper shell can be reduced through the shock absorbing assembly 80, thereby reducing the adverse effect of the vibration source generated by the power assembly 30 on the user's feel.

[0116] In some embodiments, the guide rod 84 and the linear bearing 85 are provided with multiple groups to improve the accuracy of the upper shell moving relative to the lower shell. In one embodiment, the guide rod 84 and the linear bearing 85 are provided with two groups and are respectively arranged on the front and rear sides of the tile paving machine.

[0117] In some embodiments, the tile paving machine further includes a shock-absorbing pad, which is arranged on the support seat 82 and arranged horizontally to reduce vibration in the horizontal direction. The shock-absorbing pad is an elastic ring, and the number of the elastic rings is four, and the four elastic rings are arranged in groups of two and are respectively arranged on the left and right sides of the support seat 82. In one embodiment, the shock-absorbing pad is a silicone ring or a rubber ring. Of course, other structures that can reduce vibration are also applicable to the tile paving machine of the present application. For example, a buffer silicone pad is added between the main handle 111 and the shell body 13.

[0118] The average output power of the tile paving machine is greater than or equal to 60 W and less than or equal to 200 W. In one embodiment, the average output power of the tile paving machine is 60 W; in one embodiment, the average output power of the tile paving machine is 70 W; in one embodiment, the average output power of the tile paving machine is 80 W; in one embodiment, the average output power of the tile paving machine is 90 W; in one embodiment, the average output power of the tile paving machine is 100 W; in one embodiment, the average output power of the tile paving machine is 110 W; in one embodiment, the average output power of the tile paving machine is 120 W.

[0119] In the embodiments of the present application, in order to make the tile paving machine compact and light in weight, a structure such as a fan specifically used for heat dissipation is generally not provided in the tile paving machine. In some embodiments, the tile paving machine relies on the natural heat dissipation of the housing 10. In order to improve the heat dissipation performance of the tile paving machine, heat dissipation structures such as heat dissipation holes and heat dissipation fins may be provided on the housing 10, and heat dissipation structures such as heat dissipation holes and heat dissipation fins may also be provided on the second housing 15 and / or the third housing 16 to enhance the heat dissipation effect on the motor 31 and the circuit board assembly 40.

[0120] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the above embodiments do not limit the present application in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present application.
