Description

Technical Field

[0001] The utility model relates to an electric kitchen appliance, in particular to a soybean milk machine. Background Art

[0002] There are three main ways to install the power board in the existing motor-mounted soybean milk machine. The first installation method is to set the power board on the machine head. For example, patent No. CN201420850956.6 discloses a soybean milk machine, in which the control board is installed on the transition bracket between the upper cover and the lower cover of the machine head. At this time, the display panel is usually also installed on the machine head. On the one hand, in order to accommodate the control board and the display panel, the machine head is larger in size, which makes the machine head bulky and inconvenient for users to use; on the other hand, the control board needs to be connected to the power transmission harness and the signal detection harness. The power transmission harness is a strong power harness, and the signal detection harness is a weak power harness. The strong power harness and the weak power harness are connected to the control board together. When the control board is working, the electromagnetic generated by the strong electric signal will interfere with the weak signal, affecting the detection sensitivity and hindering the normal operation of the soybean milk machine. The second installation method is to set the power board on the cup body. For example, patent No. CN201720103814.7 discloses a soymilk machine, in which the power board is installed on the cup body. At this time, the signals generated by the anti-overflow electrode and temperature sensor and other signal detection devices on the machine head need to be transmitted to the power board by separate wiring harnesses, resulting in more signal transmission wiring harnesses, so that the machine head and the cup body need to have a larger wiring space. During installation and maintenance, too many wiring harnesses will affect the installation and maintenance efficiency. The third installation method is to respectively set circuit boards on the machine head and the cup body. For example, patent CN201721889594.1 discloses a soymilk maker, in which the machine head is provided with a machine head circuit board, the cup body is provided with a cup body circuit board, the machine head circuit board is provided with a processing unit, and the processing unit includes a signal acquisition unit and a load drive unit. The signal acquisition unit is responsible for detecting and processing the signals generated by the temperature sensor and the anti-overflow electrode, and the load drive unit is responsible for driving the load motor. The detection signal is a weak current signal, and the load drive is a strong current drive. The strong and weak current signals are connected to the machine head circuit board together. The electromagnetic generated by the strong current signal will interfere with the detection signal, affect the detection sensitivity, and thus affect the normal operation of the soymilk maker.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, the embodiment of the utility model discloses a soymilk machine, including a machine head 1, a cup body 2, and a coupler assembly. The machine head 1 includes a machine head upper cover and a machine head lower cover, a motor 4 is arranged in the machine head lower cover, and a power supply board 3 is arranged on the cup body. A transition bracket 8 is arranged on the machine head lower cover, and a protrusion 11 extending horizontally inward is arranged on the inner wall of the transition bracket 8. A baffle 12 extending vertically upward is arranged on the edge of the protrusion 11 away from the inner wall of the transition bracket. The inner wall of the transition bracket 8, the protrusion 11 and the baffle 12 are enclosed to form a receiving cavity, and the signal board is sealed and installed in the receiving cavity. Specifically, the signal board includes a substrate 5 and a glue potting box 7, and the substrate 5 is glued and sealed in the glue potting box 7. A buckle 13 is arranged on the inner wall of the transition bracket 8 and the inner wall of the baffle 12. After the substrate 5 is glued and sealed in the glue potting box 7, the glue potting box 7 is placed in the receiving cavity, and the buckle 13 is buckled on the upper end of the side wall of the glue potting box 7 to fix the glue potting box 7 in the receiving cavity. Lugs 71 are provided on both sides of the glue potting box 7 , and the protruding portion 11 is provided with vertically upward screw columns, which correspond to the lugs 71 . The screws pass through the lugs 71 and are threadedly connected with the screw columns to further fix the glue potting box 7 .

[0027] On one side of the signal board, the protrusion 11 is also provided with an anti-overflow electrode 6 extending downward from the machine head, and the anti-overflow electrode 6 is electrically connected to the signal board through a wire. After the signal board receives the detection signal transmitted by the anti-overflow electrode, it is processed and electrically connected to the power board through a port of the coupler assembly, thereby completing the transmission of the signal. Specifically, the coupler assembly includes an upper coupler arranged on the machine head and a lower coupler arranged on the cup body. The signal board is connected to a pin of the upper coupler through a wire in the machine head. After the cup body and the machine head are assembled, the pin contacts the plug spring, and the plug spring is electrically connected to the power board through another wire in the cup body. Therefore, after the signal board receives the detection signal, it is processed and the processed result is transmitted to the power board through a wire in the machine head and the upper and lower couplers and another wire in the cup body.

[0028] The lower cover of the machine head is provided with a step structure, the protrusion is located above the step, a sealing member is provided between the protrusion and the step, the anti-overflow electrode passes through the sealing member and the step in sequence and extends out of the machine head, and the protrusion presses the sealing member onto the step. Specifically, a through hole for the anti-overflow electrode to pass through is provided on the step, the sealing member can be a silicone pad, and the silicone pad includes a sealing sleeve sleeved on the outside of the anti-overflow electrode and a holding portion connected to the sealing sleeve and held on the step, the anti-overflow electrode is interference-fitted with the through hole through the sealing sleeve, and the protrusion presses the holding portion onto the step.

[0029] In this embodiment, the signal board and the motor are electrically connected to the power board through other ports of the coupler assembly, so that the power board supplies power to the signal board and the motor. Specifically, the signal board and the motor are connected to the pins of the upper coupler located at the head through multiple wire harnesses. After the cup body and the head are assembled, the pins are in contact with the plug springs, and the plug springs are electrically connected to the power board through other wire harnesses in the cup body. A plurality of wire slots 16 are provided on the inner wall of the transition bracket, and the wire harnesses connecting the signal board and the motor to the upper coupler can be inserted into the wire slots.

[0030] The signal board is arranged in the receiving cavity of the transition bracket, and the power board is arranged in the cup body. The signal board processes the signal in the receiving cavity, and the processed signal is transmitted to the power board through a port of the coupler assembly, which avoids the electromagnetic interference of the strong electric signal on the signal board, can improve the detection sensitivity, and also avoids the connection of each detection device with the power board through different ports, reduces the number of coupler ports, can reduce the volume of the coupler and the number of wiring harnesses, and is convenient for installation and maintenance. The baffles on the bottom wall and the side wall of the receiving cavity can block the heat generated when the motor is working to a certain extent, and avoid the heat generated when the motor is working to be transferred to the signal board, affecting the sensitivity of signal detection. The signal board is sealed with glue to isolate the signal board from the outside world. When the soymilk machine is working, the water vapor generated by high temperature enters the machine head, and the water vapor may condense into water droplets when it is cooled. After the signal board is sealed with glue, the water droplets can be prevented from entering the signal board, ensuring the safe and effective operation of the electronic device. The anti-overflow electrode is arranged on the protruding part, and the sealing member is pressed onto the step through the protruding part. There is no need to set up an additional installation position for the anti-overflow electrode, and the space of the protruding part is fully utilized. At the same time, the protruding part presses the sealing member to better seal the position where the anti-overflow electrode extends out of the machine head, thereby preventing the slurry from entering the machine head from the position where the anti-overflow electrode extends out when the soymilk machine is working.

[0031] Of course, the location of the accommodating cavity is not limited to being set on the transition bracket. The machine head may include a machine head upper cover and a machine head lower cover, the motor is arranged in the machine head lower cover, and the accommodating cavity is arranged on the inner wall of the machine head upper cover. Specifically, the inner wall of the machine head upper cover is provided with a protrusion extending horizontally inward, and the edge of the protrusion away from the inner wall of the machine head upper cover is provided with a baffle extending vertically upward, and the accommodating cavity is formed by the inner wall of the machine head upper cover, the protrusion and the baffle. The accommodating cavity may also be arranged on the machine head lower cover. In this case, the machine head lower cover includes a metal lower cover and a plastic lower cover located inside the metal lower cover, the motor is arranged inside the plastic lower cover, the inner wall of the plastic lower cover is provided with a protrusion extending horizontally inward above the motor, and the edge of the protrusion away from the inner wall of the plastic lower cover is provided with a baffle extending vertically upward, and the accommodating cavity is formed by the inner wall of the plastic lower cover, the protrusion and the baffle.

[0032] The shape of the protrusion can be adjusted according to the shape of the signal plate. The central angle formed by the two connecting ends of the protrusion and the inner wall of the machine head and the center of the machine head can be an acute angle or an obtuse angle. Of course, Figure 4 As shown, the protrusion can also be arranged around the head inner wall. As mentioned above, the head inner wall can be the inner wall of the transition bracket on the head lower cover, or the inner wall of the head upper cover or the inner wall of the plastic lower cover inside the metal lower cover.

[0033] Regarding the sealing of the signal board, in addition to sealing the substrate in a glue filling box, the signal board can also be directly sealed in the accommodating cavity by glue filling. In this case, a partition extending vertically upward can be provided on the protrusion between the signal board and the anti-overflow electrode. The two sides of the partition are respectively connected to the inner wall of the machine head and the baffle. The partition separates the accommodating cavity into two parts isolated from each other, including a first accommodating cavity for accommodating the anti-overflow electrode and a second accommodating cavity for accommodating the signal board. The signal board is sealed in the second accommodating cavity by glue filling. Of course, the anti-overflow electrode and the signal board can also be sealed in the accommodating cavity by glue filling. Similarly, the inner wall of the machine head can be the inner wall of the transition bracket located on the lower cover of the machine head, or it can be the inner wall of the upper cover of the machine head or the inner wall of the plastic lower cover on the inner side of the metal lower cover.

[0034] The signal board is directly sealed in the accommodating cavity. On the one hand, it prevents water droplets generated by water vapor generated when the soymilk machine is working from condensing into the signal board when it is cold, thereby protecting the safe operation of electronic components on the signal board. On the other hand, the signal board is fixed while being sealed by glue, without the need to set up an additional fixing mechanism, thus simplifying the internal structure of the machine head and improving the efficiency of processing and assembly.

[0035] The installation position of the anti-overflow electrode is not limited to the protruding part. A mounting part extending horizontally inward can be provided on the inner wall of the machine head at one side of the signal plate, and the anti-overflow electrode is provided on the mounting part and extends downward from the machine head. The mounting part can also be provided on the inner wall of the machine head between the signal plate and the top of the motor. The mounting part can be located below the signal plate or below the side of the signal plate. In this case, the height of the horizontal plane where the mounting part is located is lower than the height of the horizontal plane where the signal plate is located. The inner wall of the machine head can also be the inner wall of the transition bracket located on the lower cover of the machine head, or the inner wall of the upper cover of the machine head or the inner wall of the plastic lower cover inside the metal lower cover.

[0036] In an embodiment of the utility model, a temperature sensor can also be arranged in the machine head. Specifically, the temperature sensor probe can be arranged at the bottom of the machine head, with one end of the temperature sensor probe extending out of the machine head, and the other end of the temperature sensor probe being connected to a wire, which is connected upward to a signal board to transmit the detected temperature signal to the signal board for processing. At this time, the signal board processes the anti-overflow signal and the temperature signal, and transmits them to the power board through a port of the coupler assembly.
