Description

TECHNICAL FIELD

[0001] The present application relates to the field of coffee machines, in particular to a water inlet assembly and a coffee machine. BACKGROUND

[0002] In order to prevent the built-in water tank from dry burning, the coffee machine often sets a water level switch in the water tank, which includes a float arranged in the water tank and a dry reed tube below the water tank. The dry reed tube triggers the controller to control the power-on state of the coffee machine through the floating state of the float, that is, when the water level in the water tank is higher than the dry reed tube, the coffee machine is in a normal power-on state. When the water level in the water tank is low and the float is close to the dry reed tube, the dry reed tube sends a signal to the electric control board under the action of the magnetic field to cut off the power supply, preventing the coffee machine from burning out due to no water running. However, with the expansion of the use scene of the coffee machine, many users will use an external water source for water supply. If only an external interface is provided on the coffee machine, it is inconvenient to connect and switch daily. In addition, even if the coffee machine is normally supplied with water from the external water source, the coffee machine will automatically cut off the power supply because the water tank is in a low liquid level state, which is inconvenient for continuous use.

The embodiments described below are merely exemplary for the purpose of explanation and are not to be understood as limiting the present application.

In relation to the orientation description, such as the orientation or position relationship indicated by up, down, front, back, left, right and the like is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, and cannot be understood as indicating or implying that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In the description of the present application, unless otherwise explicitly limited, the words such as setting, installing, connecting and the like should be broadly understood, and the skilled in the art can reasonably determine the specific meaning of the above words in the present application in combination with the specific content of the technical scheme.

[0027] Reference Figures 1-8 The present application provides a water inlet assembly, which comprises a body 100, a Hall sensor assembly 200 and a magnetic sensing piece 300; the body 100 has a water inlet channel 101 therein, the end of the body 100 is provided with a water outlet 102 and a first water inlet 103, and the bottom of the body 100 is provided with a second water inlet 104; the water outlet 102, the first water inlet 103 and the second water inlet 104 are in communication with the water inlet channel 101.

[0028] The Hall sensor assembly 200 is arranged on one side of the body 100 and is used for sensing and obtaining the insertion state of the magnetic sensing piece 300; optionally, the Hall sensor assembly 200 comprises a Hall sensor and a driving board body, the pins of the Hall sensor are welded with the driving board body, without the need for additionally setting a circuit board, so that the overall volume of the Hall sensor assembly 200 is smaller, facilitating the arrangement on the water inlet assembly. It can be understood that the present application is not an improvement on the Hall sensor and the like assembly, and the skilled in the art can select and use the existing Hall sensor for configuration, and the specific principle will not be described here.

[0029] The magnetic sensing piece 300 is inserted and pulled along the second water inlet 104, the magnetic sensing piece 300 can be connected with the second water inlet 104 in cooperation, and the magnetic sensing piece 300 is arranged in position corresponding to the Hall sensor assembly 200. In some specific embodiments, the shape of the magnetic sensing piece 300 can be cylindrical, blocky or the like, and the magnetic sensing piece 300 can also be directly configured to correspond to the caliber of the second water inlet 104. On the one hand, the second water inlet 104 can be sealed, and on the other hand, after the magnetic sensing piece 300 is inserted into the second water inlet 104, the insertion and pulling action of the magnetic sensing piece 300 will change the magnetic field around the Hall sensor, and the Hall sensor will transmit the change signal to the driving board body, thereby indicating the opening and closing state of the second water inlet 104.

[0030] Thus, the water inlet assembly is in communication with the water inlet channel 101 through the first water inlet 103 and the second water inlet 104, forming a double-path water source mode, which can meet various water supply requirements. The water supply can be achieved by connecting the first water inlet 103 with a water tank, or by connecting the second water inlet 104 with a water faucet or a barrel of water. When the magnetic sensing piece 300 is inserted into or pulled out of the second water inlet 104, the Hall sensor can obtain the insertion state of the magnetic sensing piece 300, which can be used as an indication of the opening and closing of the second water inlet 104.

[0031] In some embodiments, the water inlet assembly further comprises a stop piece 400. When the coffee machine is used with a self-provided water tank, the stop piece 400 can be used to block the second water inlet 104 to ensure the sealing. Specifically, the stop piece 400 comprises a first connecting part 410, one end of the first connecting part 410 is connected with the second water inlet 104, so that the first connecting part 410 is inserted into the second water inlet 104. The first connecting part 410 is provided with a receiving groove 411, and the magnetic sensing piece 300 is arranged in the receiving groove 411. The magnetic sensing piece 300 is inserted into the receiving groove 411, and then the first connecting part 410 is connected with the second water inlet 104, so that when the first connecting part 410 is inserted into the second water inlet 104, the magnetic sensing piece 300 is accurately located at a position corresponding to the Hall sensor.

[0032] Since the first connecting part 410 lacks additional fixation, the stop piece 400 may be loosened due to vibration when the self-provided water tank is used for water supply. When the external water source is used, the first connecting part 410 also needs to be separately removed and placed. Once the stop piece 400 is loosened and falls off or is lost, it will not only affect the normal use of the coffee machine, but also bring inconvenience to find or replace the parts. Thus, with reference to Figure 4 and Figure 5 In yet another embodiment, the stop piece 400 further comprises a second connecting part 420, the first connecting part 410 is connected with the second connecting part 420, and the bottom of the body 100 is provided with a mounting opening 105, the second connecting part 420 is connected with the mounting opening 105 to fix one end of the stop piece 400 on the body 100, so that when the first connecting part 410 is removed, it is not necessary to additionally fix and place the first connecting part 410. Further, with reference to Figure 1 The second connecting part 420 can also be inserted into one end of the mounting opening 105 and fixed by a latch, so that the second connecting part 420 is fixed with the body 100.

[0033] Then, with reference to Figures 1-3In order to facilitate the fixation of the Hall sensor assembly 200, in some embodiments, the body 100 is provided with a mounting groove 110 on one side, and the Hall sensor assembly 200 can be fixedly inserted into the mounting groove 110. Since the shape of the Hall sensor assembly 200 is matched with the mounting groove 110, the Hall sensor assembly 200 can be fixed by being inserted into the mounting groove 110, so as to ensure that the relative position of the Hall sensor assembly 200 and the second water inlet 104 inside the body 100 is appropriate, and the Hall sensor assembly 200 can accurately sense the insertion state of the magnetic induction piece 300 without repeatedly matching the position of the magnetic induction piece 300.

[0034] Next, referring to Figure 4 and Figure 5 , in some embodiments, the bottom of the body 100 is provided with a recess 120 and a flip cover 130 corresponding to the recess 120, one side of the flip cover 130 is movably connected with the body 100, and the second water inlet 104 and the stopper 400 are arranged in the recess 120. For example, the flexible opening and closing of the flip cover 130 can be realized by a hinge, so as to arrange the second water inlet 104 and the stopper 400 in the recess 120. When the flip cover 130 is closed, the components in the recess 120 can be protected. When the coffee machine needs to operate the second water inlet 104 or the stopper 400, the flip cover 130 can be opened.

[0035] Further, referring to Figure 4 and Figure 6 , the side of the flip cover 130 facing the recess 120 is provided with a protruding part 131, and the protruding part 131 is arranged corresponding to the second water inlet 104. When the second water inlet 104 is inserted with the stopper 400 and the flip cover 130 is closed, the protruding part 131 gradually approaches the second water inlet 104, so that when the flip cover 130 is closed, the protruding part 131 can abut against the outer side end surface of the first connecting part 410 of the stopper 400. That is, after the flip cover 130 is closed, the protruding part 131 on the flip cover 130 exerts pressure on the first connecting part 410 of the stopper 400, so as to prevent the first connecting part 410 from loosening after being connected, and further strengthen the sealing performance when the first connecting part 410 is connected with the second water inlet 104. At the same time, after the protruding part 131 exerts pressure on the first connecting part 410, the magnetic induction piece 300 also has a proper insertion depth, so that the magnetic induction piece 300 can be inserted in place, the position of the magnetic induction piece 300 can correspond to the sensing area of the Hall sensor assembly 200, and the Hall sensor assembly 200 can be accurately triggered.

[0036] In addition, referring to Figure 4 and Figure 5The other side of the flip cover 130 is provided with a bayonet 133, and the groove 120 is provided with a clamping hook 121 corresponding to the bayonet 133, and the clamping hook 121 is buckled with the bayonet 133. Because the bayonet 133 and the clamping hook 121 are matched with each other, when the flip cover 130 is closed, the bayonet 133 is buckled with the clamping hook 121 to fix the position of the flip cover 130, and the closed state of the flip cover 130 is stable. When the flip cover 130 needs to be opened, an external force is applied to separate the clamping hook 121 from the bayonet 133. Further, the flip cover 130 is also provided with a lifting part 132 to facilitate the opening and closing of the flip cover 130.

[0037] In some embodiments, as Figure 7 needed, the water inlet assembly further comprises a water inlet pipe 500. Specifically, the water inlet pipe 500 comprises a joint segment 510 and a connecting segment 520 in communication with each other, and the water inlet pipe 500 is provided with a blocking ring 530, the joint segment 510 and the connecting segment 520 are separated by the blocking ring 530, the joint segment 510 is connected with the water inlet channel 101, and the liquid outlet hole 511 of the joint segment 510 corresponds to the water outlet 102. The external water source is introduced into the water inlet channel 101 through the water inlet pipe 500, and the water is guided to the water outlet 102 through the communicated liquid outlet hole 511.

[0038] Further, referring to Figure 8 , the diameter of the blocking ring 530 is greater than the diameter of the second water inlet 104. The larger diameter makes it impossible to pass through the second water inlet 104. When the joint segment 510 of the water inlet pipe 500 is inserted into the water inlet channel 101, the blocking ring 530 is in close contact with the edge of the second water inlet 104, limiting the installation depth of the water inlet pipe 500 on the water inlet assembly, so that the liquid outlet hole 511 of the joint segment 510 can accurately correspond to the water outlet 102, ensuring that the water flow can smoothly flow from the water inlet pipe 500 into the water inlet channel 101 and flow out through the water outlet 102.

[0039] In order to enhance the sealing performance between the joint segment 510 and the water inlet channel 101, the joint segment 510 is sleeved with a first sealing ring 540 and a second sealing ring 550 arranged at intervals, and when the joint segment 510 is inserted into the water inlet channel 101, the first water inlet 103 is arranged between the first sealing ring 540 and the second sealing ring 550, forming a double-layer sealing structure, and when the joint segment 510 is inserted into the water inlet channel 101, it is in close contact with the inner wall of the water inlet channel 101, preventing water leakage from the gap between the joint segment 510 and the water inlet channel 101.

[0040] The application also provides a coffee machine, which comprises a water pump and a water tank, and further comprises the water inlet assembly according to any one of the preceding technical solutions, the water outlet pipe of the water tank is connected with the first water inlet 103 of the water inlet assembly, and the water pump is connected with the water outlet 102 of the water inlet assembly.

[0041] When using the water tank for water supply, the water pump is started to provide power to suck water from the pipeline of the self-provided water tank, and the water enters the first water inlet 103 of the water inlet assembly through the water outlet pipe and then flows into the water inlet channel 101; when using an external water source, the water flows into the water inlet channel 101 from the second water inlet 104, is extracted from the water outlet 102 in the water inlet channel 101, and is delivered to the brewing device of the coffee machine for coffee making.

[0042] In the conventional coffee machine water supply mode switching technical solution, additional sensors and circuit boards are often required to achieve multi-mode water supply. This not only occupies a large amount of limited space inside the coffee machine, but also makes the design and assembly process extremely complex. However, by providing a water inlet assembly in the coffee machine and reasonably connecting and configuring the control assembly and the Hall sensor assembly 200, the switching of the water supply mode can be achieved.

[0043] When using the self-provided water tank of the coffee machine, the magnetic induction piece 300 is only inserted into the second water inlet hole, and the Hall sensor assembly 200 immediately senses and sends a corresponding signal. At this time, the control assembly is configured to start the active monitoring function of the float in the self-provided water tank after receiving the signal. In this way, dry burning of the water tank can be prevented, and safe and stable operation of the coffee machine can be ensured.

[0044] When switching to the external water source water supply mode, the magnetic induction piece 300 is pulled out, and the Hall sensor assembly 200 converts this state change into a signal and transmits it to the control assembly. After receiving the signal, the control assembly adjusts the float function to an auxiliary monitoring mode. In this mode, even if the water level is below the float position, the coffee machine will not automatically cut off the power, thereby breaking through the limitation of the traditional water level switch.

[0045] Therefore, by providing the water inlet assembly, the internal structure of the coffee machine is simplified, the internal space of the coffee machine is saved, the connection is convenient to use, and the user experience of the coffee machine is further improved.
