[0024] A wall-breaking machine of the present utility model will be described in conjunction with the accompanying drawings.
[0025] As Figures 1 to 7 shown, a wall-breaking machine includes a cup body 1, a cover body 2, a magnet 3, a reed switch 4, and a main control circuit board 5. The cover body 2 includes an inner cover 21 and an outer cover 22. The cup body 1 has an open upper end. The inner cover 21 is hermetically covered on the open upper end of the cup body 1 to form a wall-breaking cavity in the cup body 1. The outer cover 22 is covered on the inner cover 21. The inner cover 21 extends toward the handle 11 of the cup body 1 to form an extension portion 211. The magnet 3 is installed in the extension portion 211. The reed switch 4 and the main control circuit board 5 are installed in the cup body 1. When the inner cover 21 is covered, the reed switch 4 is attracted and closed under the action of the magnet 3. A wire groove 12 is provided inside the handle 11. The reed switch 4 is directly electrically connected to the main control circuit board 5 through the wire groove 12. With the detection structure of the reed switch 4, since the reed switch 4 does not require additional power supply and signal amplification and directly cooperates with the magnet 3 to form the on / off of the loop where the reed switch 4 is located, it can be directly applied to the main control circuit board 5, thereby reducing the overall manufacturing cost of the wall-breaking machine; the connection line between the reed switch 4 and the main control circuit board 5 passes through the wire groove 12 in the handle 11, which does not occupy the space inside the main body of the cup body 1, so that the wall-breaking cavity in the cup body 1 can be made larger.
[0026] As Figure 4As shown, the extension part 211 extends outward. The extension part 211 further includes a detachable mounting base 213 which is detachably connected by screws. During assembly, first install the magnet 3 on the mounting base 213, and then fix the mounting base 213 with screws so that the magnet 3 is clamped and fixed in the extension part 211. In order to facilitate covering the inner cover 21, the outer cover 22 is provided with a first avoidance opening 221 at a position corresponding to the extension part 211, so that when the outer cover 22 is covered on the inner cover 21, the extension part 211 can be accommodated in the first avoidance opening 221.
[0027] As Figure 2 shown, the main body of the cup body 1 includes an outer shell 13 and an inner liner 14. An installation cavity is formed between the outer shell 13 and the inner liner 14. An upper connection part 113 and a lower connection part 114 are formed between the handle 11 and the outer shell 13. Through holes are provided at the upper connection part 113 and the lower connection part 114, which can facilitate the connection line of the reed switch 4 to pass through. The reed switch 4 is installed at the top of the installation cavity, corresponding to the position of the upper connection part 113. The main control circuit board 5 is installed at the bottom of the installation cavity, corresponding to the position of the lower connection part 114. The connection line of the reed switch 4 and its supporting structure do not occupy the size of the inner liner 14, so that the inner liner 14 of the cup body 1 can be made larger.
[0028] As Figure 3 shown, a reinforcing plate 111 is provided inside the handle 11. A notch 112 for forming a wire groove 12 is provided on the reinforcing plate 111. The reinforcing plate 111 strengthens the structural strength of the handle 11 and does not affect the passing of the connection line of the reed switch 4.
[0029] As Figure 2 shown, it further includes a brushless motor 6 and a cutter 7. The brushless motor 6 is installed in the installation cavity. The output shaft of the brushless motor 6 extends into the wall-breaking cavity. The cutter 7 is detachably installed on the output shaft. By adopting the brushless motor 6, the wall-breaking machine will not generate carbon powder during operation, can work more quietly, and also has better frequency conversion technology, making it more convenient to break the wall.
[0030] It also includes a control module which is used to control the 6-commutation or 12-commutation and the rotational speed of the brushless motor 6. The control module includes an electronic commutator, a current controller and a position sensor. The DC brushless motor realizes brushless drive through electronic commutation technology, replacing the carbon brush and mechanical commutator in the traditional DC motor. The electronic commutator controls the current direction of the motor winding through a control circuit, thus realizing the continuous rotation of the motor; it detects the relative position of the rotor with respect to the stator winding during movement and converts this position information into an electrical signal. These electrical signals are then sent to the current controller to timely adjust the direction and magnitude of the current; the current controller uses Pulse Width Modulation (PWM) technology to control the magnitude of the current. By adjusting the duty cycle of the PWM signal, it controls the on-time and off-time of the switching element (such as MOSFET), thereby controlling the average value of the current and further controlling the rotational speed and torque of the motor; the circuit diagram of the control module is as Figure 8 shown.
[0031] As Figure 2 and Figure 4 shown, a sealing ring 212 is provided at the bottom of the inner cover 21. The sealing ring 212 presses against the inner side wall of the inner container 14, so that the breaking-wall cavity formed in the inner container 14 can be kept sealed.
[0032] As Figure 1 shown, an exhaust hole 215 is provided on the inner cover 21. The exhaust hole 215 is not blocked by the outer cover 22. The cover body 2 extends downward and inward with a first baffle 214. The first baffle 214 is arranged around the exhaust hole 215. The first baffle 214 can prevent liquid such as soy milk from splashing onto the exhaust hole 215 during the working process of the wall breaker, such as making soy milk. In order to facilitate covering the inner cover 21, a second avoidance opening 222 is provided at the position corresponding to the exhaust hole 215 on the outer cover 22, so that when the outer cover 22 covers the inner cover 21, the exhaust hole 215 can be communicated with the outside through the second avoidance opening 222 for exhausting steam.
[0033] As Figure 1 and Figure 2 shown, it also includes a silica gel plug 216. The silica gel plug 216 is installed on the exhaust hole 215. An exhaust channel 217 is provided in the silica gel plug 216. A handle 218 is provided at the top of the outer cover 21. The outlet of the exhaust channel 217 faces away from the handle 218. As Figure 2 shown, the exhaust channel 217 is L-shaped. The inlet of the exhaust channel 217 is communicated with the breaking-wall cavity where the first baffle 214 is located, so that the steam generated during the operation of the wall breaker can be discharged from the exhaust channel 217. The outlet of the exhaust channel 217 faces away from the handle 218, thus avoiding the discharged steam from heating the handle 218 and preventing the user from being scalded when holding the handle 218.
[0034] AsFigure 6 and Figure 7 As shown, it further includes a power supply assembly 15. A clamping port 131 is provided on the cup body 1. Specifically, the clamping port 131 is provided on the outer shell 13. For example Figure 6 As shown, the outer shell 13 includes an upper and a lower shell. The upper and lower shells cooperate to form the clamping port 131. The power supply assembly 15 is clamped and installed in the clamping port 131, that is, the power supply assembly 15 is clamped and installed between the upper and lower shells.
[0035] For example Figure 6 and Figure 7 As shown, the power supply assembly 15 includes a socket 151, a mounting bracket 152 and a second baffle 153. The socket 151 and the second baffle 153 are installed on the mounting bracket 152. The second baffle 153 extends upward with a first limiting strip. The mounting bracket 152 extends upward with a second limiting strip 1521. A limiting hole 1531 is formed in the first limiting strip. When the second baffle 153 is installed on the mounting bracket 152, the first limiting strip penetrates upward through the mounting bracket 152, so that the limiting hole 1531 can be hung on the second limiting strip 1521. The second baffle 153 is made of soft rubber material, so that the second baffle 153 is movably arranged at the socket of the socket 151. A first limiting groove 1523 is arranged behind the second limiting strip on the mounting bracket 152. A first limiting block 1511 is provided at the front end of the socket 151. The first limiting groove 1523 opens upward, so that the first limiting block 1511 can be clamped into the first limiting groove 1523 from above, so that the socket 151 is installed on the mounting bracket 152 and the socket of the socket 151 faces the second baffle 153. A second limiting block 1522 is further provided on the side wall of the mounting bracket. A second limiting groove is formed in the clamping port 131. The second limiting block 1522 cooperates with the second limiting groove, so that the whole power supply assembly 15 is clamped and installed in the clamping port 131 through the mounting bracket 152.
