[0003] As one of the components for starting the cleaner, the button plays an important role. At present, the related technology uses physical buttons to trigger the cleaner to work. However, in this way, the button circuit is abnormally squeezed during transportation or in a backpack, which will cause false triggering and serious power consumption, affecting the normal use of the cleaner and easily causing safety hazards.

The advantage of such a setting is that, since the human body itself is a conductor, that is, it has resistance, the control module on the circuit board can determine whether it is a human-operated button based on the contact resistance value of the outer surface of the first button mechanism detected, that is, when the contact resistance value is greater than or equal to the preset threshold, it is determined that it is a human-operated button, and controls the electrical appliance to start, thereby being able to largely avoid the false triggering and serious power consumption of non-human-operated buttons, ensuring safety.

DETAILED DESCRIPTION

[0041] In order to enable those skilled in the art to better understand the disclosed solution, the technical solution in the disclosed embodiment will be clearly and completely described below in conjunction with the drawings in the disclosed embodiment. Obviously, the described embodiment is only a part of the disclosed embodiment, not all of the embodiments. Based on the embodiments in the disclosed embodiment, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the disclosed embodiment.

[0042] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described can be implemented in sequences other than those illustrated or described herein.

[0043] In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or modules is not necessarily limited to those steps or modules explicitly listed, but may include other steps or modules not explicitly listed or inherent to these processes, methods, products, or apparatuses.

[0044] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other. Figures 1 to 9 The key module, the cleaner, the control method and the storage medium provided by the embodiments of the present disclosure are described in detail.

[0045] Please refer to Figure 1 , which is a structural block diagram of a key module provided by an embodiment of the present disclosure. The key module 10 includes a first key mechanism 11 and a circuit board 12, and the circuit board 12 includes a control module 121. Among them, when the first key mechanism 11 is subjected to external force, the first key mechanism 11 is electrically connected to the circuit board 12, and the control module 121 detects the contact resistance value of the outer surface of the first key mechanism 11, and when the contact resistance value is greater than or equal to a preset threshold, controls the electrical appliance to start; when the contact resistance value is less than the preset threshold, keeps the electrical appliance from starting. Since the human body itself is a conductor, that is, it has resistance, the control module 121 on the circuit board 12 can determine whether it is a manually operated key according to the contact resistance value of the outer surface of the first key mechanism 11 detected, that is, when the contact resistance value is greater than or equal to the preset threshold, it is determined that it is a manually operated key, and controls the electrical appliance to start, thereby greatly avoiding the false triggering and serious power consumption of non-human operated keys, ensuring safety.

[0046] Optionally, in the embodiment of the present disclosure, the first key mechanism 11 includes but is not limited to a key body 111 and a conductive member 112 disposed on the key body 111, and a metal contact 122 corresponding to the conductive member 112 is disposed on the circuit board 12, which is used to be electrically connected to the conductive member 112 when the key body 111 is subjected to an external force. The advantages of such a setting are simple structure, high sensitivity, and convenience for miniaturization of the key module 10.

[0047] Optionally, the embodiments of the present disclosure can control the start of the electrical appliance by an electrical signal. Alternatively, some embodiments of the present disclosure can also be combined with the second button mechanism 13 to control the start of the electrical appliance, such as Figure 2 As shown, the key module 10 also includes a second key mechanism 13, which is arranged on the circuit board 12 and is located below the key body 111. Therefore, when the key body 111 is subjected to external force, the key body 111 can press the second key mechanism 13, so that the control module 121 controls the start of the electrical appliance according to the pressing state and the contact resistance value. The advantage of this arrangement is that by stacking the two key mechanisms, that is, the first key mechanism 11 is located above the second key mechanism 13, the two parameters of the contact resistance value of the outer surface of the first key mechanism 11 and the pressing state of the second key mechanism 13 can be combined to achieve double judgment, and the reliability is strong.

Alternatively, in other embodiments of the present disclosure, the conductive member 112 is arranged around the key body 111, and the metal contact 122 is arranged around the second key mechanism 13. The advantage of such an arrangement is that the conductive member 112 can evenly disperse the external force on the key body 111, so that the key body 111 will not easily tilt up due to unbalanced force, thereby extending the service life, and at the same time, the conductive member 112 and the metal contact 122 can be well and firmly electrically connected without offset.

[0049] Furthermore, in the disclosed embodiment, the height (h1) of the conductive member 112 is greater than the height (h2) of the second button mechanism 13, and is less than the distance (d) between the button body 111 and the second button mechanism 13, thereby preventing the conductive member 112 from accidentally contacting the metal contact 122 when the button body 111 is not subjected to external force, and enabling the conductive member 112 to be quickly electrically connected to the metal contact 122 when the button body 111 is subjected to external force, thereby improving reliability. For example, the conductive member 112 may be a metal column 1123, and the advantage of such a setting is that it is convenient for processing and manufacturing, and reduces production costs. For another example, the bottom end of the metal column 1123 may also be provided with a protrusion 1124, and the protrusion 1124 is integrally formed with the metal column 1123, thereby being more solid and greatly extending the service life.

[0050] Optionally, in the embodiments of the present disclosure, a reset member 14 is further provided between the first button mechanism 11 and the second button mechanism 13, thereby providing sufficient push force to facilitate the button mechanism to quickly return to the starting position. For example, the reset member 14 can be a spring, which is sleeved on the second button mechanism 13 and fixed to the circuit board 12 at the bottom. The advantage of such a setting is that the structure is simple and the cost is low. Alternatively, in some embodiments of the present disclosure, the bottom of the button body 111 is made of elastic material, and the button mechanism can also be reset in this case.

[0051] Optionally, the control module 121 in the embodiment of the present disclosure includes but is not limited to a control chip 1211, a resistance detection unit 1212, and a start unit 1213. Among them, the first input terminal (A1) of the resistance detection unit 1212 is connected to the power supply (VDD), the second input terminal (A2) of the resistance detection unit 1212 is connected to the first terminal (AD_KEY) of the control chip 1211, the third terminal (A3) of the resistance detection unit 1212 is grounded (GND), and the fourth terminal (A4) of the resistance detection unit 1212 is connected to the first terminal (B1) of the second key mechanism 13; and the first terminal (D1) of the start unit 1213 is connected to the power supply (VDD), the second terminal (D2) of the start unit 1213 is connected to the second terminal (OPEN_IO) of the control chip 1211, the third terminal (D3) of the start unit 1213 is connected to the second terminal (B2) of the second key mechanism 13, and the fourth terminal (D4) of the start unit 1213 is connected to the third terminal (KEY1) of the control chip 1211. The advantage of this arrangement is that the resistance detection unit 1212 can quickly detect the contact resistance value of the outer surface of the first button mechanism 11, so that the control chip 1211 can control the electrical appliance to start through the start unit 1213 based on the comparison result between the contact resistance value and the preset threshold, which is efficient and convenient.

[0052] For example, Figure 3 As shown, for example, in some embodiments of the present disclosure, the control chip 1211 may be a BF7615BM28 chip; Figure 4 As shown, in some embodiments of the present disclosure, the resistance detection unit 1212 includes but is not limited to a first metal contact 1221, a second metal contact 1222, a first resistor R1 and a capacitor C1, wherein the first metal contact 1221 is connected to a power supply (VDD), the second metal contact 1222 is respectively connected to a first end (AD_KEY) of the control chip 1211, a first end (a1) of the first resistor R1 and a first end (a2) of the capacitor (C1), a second end (a3) ​​of the first resistor R1 is grounded (GND), a second end (a4) of the capacitor C1 is grounded (GND), and is connected to a first end (B1) of the second key mechanism 13; still as shown in FIG. Figure 4 As shown in the figure as an example, in some embodiments of the present disclosure, the startup unit 1213 includes but is not limited to a second resistor R2, a third resistor R3, a field effect transistor Q1, a fourth resistor R4 and a fifth resistor R5, wherein the first end (d1) of the second resistor R2 and the first end (d2) of the field effect transistor Q1 are both connected to the power supply (VDD), the first end (d3) of the third resistor R3 is connected to the second end (OPEN_IO) of the control chip 1211, the second end (d4) of the third resistor R3 is respectively connected to the second end (d5) of the second resistor R2 and the second end (d6) of the field effect transistor Q1, the third end (d7) of the field effect transistor Q1 is connected to the first end (d8) of the fourth resistor R4, the second end (d9) of the fourth resistor R4 is respectively connected to the first end (d10) of the fifth resistor (R5) and the third end (KEY1) of the control chip (1211), and the second end (d11) of the fifth resistor R5 is connected to the second end (B2) of the second key mechanism 13.

[0053] The key module provided in the embodiment of the present disclosure determines whether the key is manually operated based on the contact resistance value detected on the outer surface of the first key mechanism through the control module on the circuit board. That is, when the contact resistance value is greater than or equal to a preset threshold, it is determined that the key is manually operated, and the electrical appliance is controlled to start, thereby greatly avoiding false triggering and serious power consumption of non-human operation keys, ensuring safety.

[0054] Based on the above examples, please refer to Figure 5 and Figure 6 , are respectively a cross-sectional structural diagram and a structural block diagram of a cleaning device provided in an embodiment of the present disclosure. The cleaning device 20 includes a cleaning body 21, a battery 22 disposed in the cleaning body 21, a motor 23 and Figures 1 to 4 In the key module 10 of the corresponding embodiment, the battery 22 and the motor 23 are respectively connected to the circuit board 12, and the first key mechanism 11 is located on the outer surface of the cleaning body 21. For example, the cleaner 20 can be a rechargeable handheld cleaning brush or a vacuum cleaner.

[0055] Alternatively, if Figure 7As shown, in the disclosed embodiment, the circuit board 12 also includes a charging module 123, a temperature detection module 124, a power detection module 125, a voltage stabilizing module 126 and a motor driving module 127, which are respectively connected to the control module 121. For example, the voltage stabilizing module 126 may include a low drop-out regulator (LDO) circuit. Among them, the temperature detection module 124 can detect the temperature of the battery 22; the power detection module 125 can detect the power of the battery 22; the control module 121 can control the charging module 123 to charge the battery 22 according to the temperature and power; the voltage stabilizing module 126 can stabilize the voltage during the operation of the battery 22; and the motor driving module 127 can drive the motor 23 to work. The advantage of this arrangement is that it improves the endurance of the cleaner 20, while ensuring charging safety and extending the service life.

[0056] Alternatively, if Figure 8 As shown, the cleaner 20 in the disclosed embodiment also includes a display panel 24 arranged on the outer surface of the cleaning body 21, and the display panel 24 is connected to the display panel terminal 128 of the circuit board 12, thereby being able to intuitively display the power level, motor gear and charging status, which is clear at a glance and greatly enhances the user's good experience.

[0057] The cleaner provided by the embodiment of the present disclosure can largely avoid false triggering and serious power consumption of non-human-operated buttons, since the button module of the cleaner can determine whether it is a manually-operated button based on the contact resistance value detected on the outer surface of the first button mechanism, thereby ensuring safety.

[0058] Based on the above examples, please refer to Fig. 9 , which is a flow chart of a control method of a key module provided by an embodiment of the present disclosure. The method can be used for Figures 1 to 4 The key module 10 of the corresponding embodiment specifically includes the following steps:

[0059] S101, detecting a contact resistance value of an outer surface of a first key mechanism.

[0060] For example, Figures 2 to 4 As shown in the figure, the initial state of the OPEN_IO port is high level, and the KEY1 port is low level. When a person presses a finger, the first conductive member 1121 of the first key mechanism 11 contacts the first metal contact 1221 of the circuit board 12, and the second conductive member 1122 contacts the second metal contact 1222. At the same time, the second key mechanism 13 is pressed, and the finger resistance, the first resistor R1 and the ground terminal GND form a detection loop.

[0061] S102, when the contact resistance value is greater than or equal to a preset threshold, the control device starts.

[0062] For example, the AD_KEY port is a detection channel, that is, when the contact resistance value is greater than or equal to the preset threshold, it is determined that the human operation key condition is met. At this time, the OPEN_IO port is switched to a low level, and the field effect tube Q1 is turned on, so that the KEY1 port becomes a high level. Furthermore, the KEY1 port generates a rising edge, which means that the key is triggered. At this time, the field effect tube Q1 can be turned off to reduce power consumption, so that the appliance starts and performs the corresponding operation.

[0063] S103, when the contact resistance value is less than the preset threshold value, the electrical appliance is kept not started.

[0064] It should be noted that if the contact resistance value is less than the preset threshold, it indicates that the button is not operated manually. At this time, the electrical appliance is kept from starting, thereby avoiding false triggering.

[0065] The control method of the button module provided in the embodiment of the present disclosure utilizes the fact that the human body is a conductor, that is, has the property of resistance, to detect the contact resistance value of the outer surface of the first button mechanism to determine whether the button is manually operated, and when the contact resistance value is greater than or equal to a preset threshold, the cleaner is controlled to start, thereby greatly avoiding false triggering and serious power consumption of non-human operated buttons, thereby ensuring safety.
