[0036] The tipping protection device provided in this application embodiment is applied to pet health companion devices, and is used to detect and protect these devices from tipping. These pet health companion devices may include devices that are beneficial to pet health, devices that provide companionship to pets, or devices that are both beneficial to pet health and provide companionship. For example, a pet health companion device may be a pet air purifier, a pet toy, or a device that integrates both pet toy and air purification.

[0037] In one embodiment, such as Figure 1 As shown, the tipping protection device includes a tipping switch circuit 110, a mechanical contact 122, and a contact feedback device 124. The tipping switch circuit 110 is installed in the pet health companion device 200 and connected to the load and live wire of the pet health companion device 200. The tipping switch circuit 110 is in a conducting or disconnected state based on the tipping state of the pet health companion device 200. The mechanical contact 122 is installed in the pet health companion device 200 and is in a released or pressed state based on the tipping state of the pet health companion device 200. The contact feedback device 124 is connected to the mechanical contact 122 and the load, and controls the working state of the load according to the released or pressed state of the mechanical contact 122. Since the tilt switch circuit 110 is in a conducting or disconnected state based on the tilt state of the pet health companion device 200, it can control the on / off state between the load and the live wire, realizing one type of tilt detection and protection. The mechanical contact 122 and the contact feedback device 124 can control the working state of the load based on the tilt state of the pet health companion device 200, realizing another type of tilt detection and protection. Thus, the tilt protection device uses dual tilt detection and protection, with mechanical tilt detection and protection as well as circuit tilt detection and protection. This can reduce the situation where the tilt protection is missed or falsely triggered when a single tilt detection device fails, improving the accuracy of tilt detection and the effectiveness of tilt protection, and improving the safety and operational reliability of the pet health companion device 200.

[0038] The tilt switch circuit 110 is installed in the pet health companion device 200. Depending on the structure of the pet health companion device 200 or other requirements, the tilt switch circuit 110 can be installed at a designated position in the pet health companion device 200, such as at the bottom. This will not affect the installation of other devices, but will also sensitively detect the tilting state of the pet health companion device 200.

[0039] In addition, the tipping switch circuit 110 connects the load of the pet health companion device 200 with the live wire. The load of the pet health companion device 200 includes devices that need to be powered in the pet health companion device 200, such as motors in the movement assembly of the pet health companion device 200, etc. The motor is used to drive the movement of the wheels of the pet health companion device 200 to move the pet health companion device 200. Alternatively, when the pet health companion device 200 is a pet purifier, the load of the pet health companion device 200 can include a disinfection assembly, etc.; when the pet health companion device 200 is a pet toy, the load of the pet health companion device 200 can include a pet teasing assembly, etc. The pet teasing assembly can attract the attention of the pet by emitting laser, sound or pattern light, and play the role of teasing the pet. The live wire refers to the live wire in the pet health companion device 200, which is responsible for transmitting electrical energy from the power source (such as mains, built-in battery B1, etc.) to the load of the pet health companion device 200 to work.

[0040] The tipping switch circuit 110 connecting the load of the pet health companion device 200 with the live wire can be that the tipping switch circuit 110 is connected between the load of the pet health companion device 200 and the live wire. The tipping switch circuit 110 is in an on or off state based on the tipping state of the pet health companion device 200. According to the structure of the tipping switch circuit 110, the correspondence between the on or off state of the tipping switch circuit 110 and the tipping state of the pet health companion device 200 includes two possible cases: in the first case, when the pet health companion device 200 is tipped, the tipping switch circuit 110 is in the on state, and when the pet health companion device 200 is not tipped, the tipping switch circuit 110 is in the off state. In the second case, when the pet health companion device 200 is tipped, the tipping switch circuit 110 is in the off state, and when the pet health companion device 200 is not tipped, the tipping switch circuit 110 is in the on state.

[0041] When the tipping switch circuit 110 is on, the live wire and the load are connected, and the electrical energy transmitted by the live wire can be normally transmitted to the load for the load to work; when the tipping switch circuit 110 is off, the live wire and the load are disconnected, and the electrical energy transmitted by the live wire cannot be normally transmitted to the load, the load loses power and does not work. Therefore, when the pet health companion device 200 is tipped, the tipping switch circuit 110 can detect the tipping state of the pet health companion device 200, and by disconnecting the connection between the load and the live wire, the load is powered off, the load stops working, the pet health companion device 200 is powered off when it is tipped, and the automatic stop running function is realized. The protection function of the pet health companion device 200 prevents the pet health companion device 200 from being damaged by tipping or causing danger to the pet, improves the user experience, and improves the working performance of the pet health companion device 200.

[0042] The mechanical contact 122 is arranged on the pet health accompanying device 200, and is in a released state or a pressed state based on the tilting state of the pet health accompanying device 200. The pressed state of the mechanical contact 122 refers to a state in which the mechanical contact 122 is pressed down, and the released state of the mechanical contact 122 refers to a state in which the mechanical contact 122 is not pressed down and is popped up. The structure and size of the mechanical contact 122 can be determined according to actual conditions, as long as the mechanical contact 122 can be in the released state and the pressed state, and specific limitations are not made.

[0043] According to different arrangement positions of the mechanical contact 122 on the pet health accompanying device 200, the correspondence between the released state or the pressed state of the mechanical contact 122 and the tilting state of the pet health accompanying device 200 includes two possible cases: in the first case, when the pet health accompanying device 200 is tilted, the mechanical contact 122 is in the released state, and when the pet health accompanying device 200 is not tilted, the mechanical contact 122 is in the pressed state. In the second case, when the pet health accompanying device 200 is tilted, the mechanical contact 122 is in the pressed state, and when the pet health accompanying device 200 is not tilted, the mechanical contact 122 is in the released state.

[0044] Exemplarily, the mechanical contact 122 can be arranged on one side of the pet health accompanying device 200 close to the placement surface. The placement surface refers to a surface for placing the pet health accompanying device 200, and is generally the ground. The pet health accompanying device 200 is arranged on the ground, which is conducive to keeping the position stable, and the pet health accompanying device 200 can also move on the ground through a movement assembly or the like to expand the working range. When the placement surface is the ground, the mechanical contact 122 can be arranged at the bottom of the pet health accompanying device 200. In this arrangement position, when the pet health accompanying device 200 is tilted, the mechanical contact 122 is in the released state, and when the pet health accompanying device 200 is not tilted, the mechanical contact 122 is in the pressed state. It can be understood that in other embodiments, the mechanical contact 122 can also be arranged at other positions of the pet health accompanying device 200, such as the side surface, and the like, which are not limited herein.

[0045] The contact feedback device 124 connects the mechanical contact 122 and the load, and controls the working state of the load according to the released state or the pressed state of the mechanical contact 122. The contact feedback device 124 can detect or sense the released state or the pressed state of the mechanical contact 122, and can receive different signals or be in different states when the mechanical contact 122 is in the released state or the pressed state.

[0046] Further, the contact feedback device 124 controls the working state of the load according to the release or pressed state of the mechanical contact 122, and the working state of the load can include working or not working. Since the release or pressed state of the mechanical contact 122 is determined based on the tipping state of the pet health companion device 200, the contact feedback device 124 can control the working state of the load according to the tipping state of the pet health companion device 200, and control the load not to work when the pet health companion device 200 tips over, so that the pet health companion device 200 stops running, and the safety hazard caused by the pet health companion device 200 continuing to run when tipping over is avoided.

[0047] In this embodiment, the tipping protection device is applied to the pet health companion device 200, and the tipping protection device includes the tipping switch circuit 110, the mechanical contact 122, and the contact feedback device 124. The tipping switch circuit 110 is arranged in the pet health companion device 200 and is connected between the load and the live wire of the pet health companion device 200. The tipping switch circuit 110 is in the on or off state based on the tipping state of the pet health companion device 200. The mechanical contact 122 is arranged in the pet health companion device 200 and is in the release or pressed state based on the tipping state of the pet health companion device 200. The contact feedback device 124 is connected between the mechanical contact 122 and the load and controls the working state of the load according to the release or pressed state of the mechanical contact 122. Since the tipping switch circuit 110 is in the on or off state based on the tipping state of the pet health companion device 200, the on or off state between the load and the live wire can be controlled, and a way of tipping detection and protection is realized. The mechanical contact 122 and the contact feedback device 124 can control the working state of the load based on the tipping state of the pet health companion device 200, and another way of tipping detection and protection is realized. Therefore, the tipping protection device uses double tipping detection and protection, and the mechanical tipping detection and protection is combined with the circuit tipping detection and protection, so that the situation that the tipping protection is missed or false triggered due to the failure of a single tipping detection device is reduced, the accuracy of tipping detection and the effectiveness of tipping protection are improved, and the safety and working reliability of the pet health companion device 200 are improved.

[0048] The structure of the tipping switch circuit 110 is not unique. In an exemplary embodiment, as shown in FIG. 2, the tipping switch circuit 110 includes a first tipping switch U2, a control switch tube Q1, and a relay K1 arranged in the pet health companion device 200. Figure 2 The first tipping switch U2 is connected to the control end of the control switch tube Q1. The first end of the control switch tube Q1 is connected to the power supply, and the second end of the control switch tube Q1 is connected to the coil of the relay K1. The coil of the relay K1 is connected between the load and the live wire of the pet health companion device 200.

[0049] The structure of the first tipping switch U2 is not limited as long as it can realize tipping detection. For example, the first tipping switch U2 can be a mechanical tipping detection switch, an electronic tipping detection switch, or other types. The mechanical electronic switch includes a ball type tipping detection switch and a mercury switch, etc. The electronic tipping detection switch includes a photoelectric tipping switch, an acceleration sensor, or a gyroscope sensor, etc.

[0050] The first tipping switch U2 is connected to the control end of the control switch tube Q1, and the first tipping switch U2 is in the on or off state based on the tipping state of the pet health accompanying device 200. When the first tipping switch U2 is in different states of on or off, the control end of the control switch tube Q1 receives different level signals, so that the control switch tube Q1 can be in the on or off state.

[0051] The first end of the control switch tube Q1 is connected to the power supply, and the second end of the control switch tube Q1 is connected to the coil of the relay K1. When the control switch tube Q1 is on, the power supply and the coil of the relay K1 are on, and the coil of the relay K1 is powered on. When the control switch tube Q1 is off, the power supply and the coil of the relay K1 are off, and the coil of the relay K1 is powered off. The type of the control switch tube Q1 is not unique, for example, it can be a triode, a MOS tube, etc.

[0052] The closing state of the contact of the relay K1 is determined based on the power-on or power-off state of the coil of the relay K1. In the first case, the contact of the relay K1 is a normally closed contact, and when the coil of the relay K1 is powered on, the normally closed contact is actuated to open, and when the coil of the relay K1 is not powered on, the normally closed contact is not actuated and remains closed. In the second case, the contact of the relay K1 is a normally open contact, and when the coil of the relay K1 is powered on, the normally closed contact is actuated to close, and when the coil of the relay K1 is not powered on, the normally closed contact is not actuated and remains open.

[0053] The contact of the relay K1 is connected to the load and the fire line of the pet health accompanying device 200. When the contact of the relay K1 is in different states of opening or closing, the connection state of the load and the fire line of the pet health accompanying device 200 is different. When the contact of the relay K1 is closed, the load and the fire line of the pet health accompanying device 200 are on, the load is powered on, and can work normally. When the contact of the relay K1 is open, the load and the fire line of the pet health accompanying device 200 are disconnected, the load is powered off, and stops working.

[0054] In this embodiment, the pouring switch circuit 110 includes a first pouring switch U2, a control switch tube Q1 and a relay K1 arranged in the pet health companion device 200. The first pouring switch U2 is connected to the control end of the control switch tube Q1, the first end of the control switch tube Q1 is connected to the power supply, the second end of the control switch tube Q1 is connected to the coil of the relay K1, and the coil of the relay K1 is connected to the load and the live wire of the pet health companion device 200. Thus, based on the detection result of the pouring state of the pet health companion device 200 by the first pouring switch U2, the control switch tube Q1 can be in a conductive or disconnected state, thereby affecting the power-on or power-off state of the coil of the relay K1 and the closed state of the contact of the relay K1, and further affecting the on-off state of the load and the live wire. The pouring protection of the pet health companion device 200 can be realized through a relatively simple circuit structure, which is conducive to improving the working reliability of the pet health companion device 200.

[0055] In one exemplary embodiment, as shown in Figure 2 the first pouring switch U2 is a photoelectric pouring switch, and the pouring switch circuit 110 further includes a first resistor R4, a second resistor R3 and a third resistor R2. The original end of the first pouring switch U2 is connected to the power supply through the first resistor R4, the auxiliary end of the first pouring switch U2 is connected to the control end of the control switch tube Q1 through the second resistor R3 and the third resistor R2, and the common end of the second resistor R3 and the third resistor R2 is connected to the power supply.

[0056] The first pouring switch U2 is a photoelectric pouring switch, and the photoelectric pouring switch detects the position change of the internal baffle or the ball to realize the detection of the pouring state. The photoelectric pouring switch has a long service life and good anti-vibration interference capability, and is suitable for high-precision or frequent triggering scenes. When the first pouring switch U2 is a photoelectric pouring switch, the photoelectric pouring switch includes a light-emitting diode and an auxiliary end triode. The original end of the first pouring switch U2 is located at one side of the light-emitting diode, and the auxiliary end of the first pouring switch U2 is located at one side of the auxiliary end triode.

[0057] The original end of the first pouring switch U2 is connected to the power supply through the first resistor R4, and the first resistor R4 can be used as a current limiting resistor to limit the current flowing from the power supply to the original end of the first pouring switch U2, thereby protecting the first pouring switch U2. It can be understood that one end of the original end of the first pouring switch U2, which is not connected to the first resistor R4, is grounded.

[0058] The secondary end of the first tipping switch U2 is connected to the control end of the control switch tube Q1 through the second resistor R3 and the third resistor R2 in sequence, and the common end of the second resistor R3 and the third resistor R2 is connected to the power supply. The second resistor R3 and the third resistor R2 can also be used as current limiting resistors. The second resistor R3 can limit the current flowing to the secondary end of the first tipping switch U2, thereby protecting the first tipping switch U2. The third resistor R2 can limit the current flowing to the control switch tube Q1, thereby protecting the control switch tube Q1. It can be understood that, in the secondary end of the first tipping switch U2, the end not connected to the second resistor R3 is grounded.

[0059] For example, if the control switch tube Q1 is a PNP triode, the control end of the control switch tube Q1 is the base of the PNP triode, the first end of the control switch tube Q1 is the emitter of the PNP triode, and the second end of the control switch tube Q1 is the collector of the PNP triode. When the pet health companion device 200 is tipped, the light-emitting diode of the primary end of the first tipping switch U2 is unshielded, causing the secondary end triode to conduct, causing the base of the PNP triode to be pulled to ground, which is a low level, so the PNP triode conducts, the coil of the relay K1 is powered, the normally closed contact of the relay K1 is actuated to open, disconnecting the load from the live wire, causing the load to lose power and stop working, and the pet health companion device 200 stops running, thereby achieving tipping protection for the pet health companion device 200. When the pet health companion device 200 is not tipped, the light-emitting diode of the primary end of the first tipping switch U2 is not unshielded, the secondary end triode of the first tipping switch U2 does not conduct, causing the base voltage of the PNP triode to be the power supply voltage, which is a high level, so the PNP triode is disconnected, the coil of the relay K1 loses power, the normally closed contact of the relay K1 does not actuate, remains closed, and keeps the load connected to the live wire, so the load is powered and works.

[0060] In this embodiment, the first tipping switch U2 is a photoelectric tipping switch, and the tipping switch circuit 110 further includes a first resistor R4, a second resistor R3, and a third resistor R2. The primary end of the first tipping switch U2 is connected to the power supply through the first resistor R4, the secondary end of the first tipping switch U2 is connected to the control end of the control switch tube Q1 through the second resistor R3 and the third resistor R2, and the common end of the second resistor R3 and the third resistor R2 is connected to the power supply. The photoelectric tipping switch as the first tipping switch U2 has the advantages of long service life and good anti-vibration interference capability, and is suitable for high-precision tipping detection or frequent tipping triggering use scenarios. By setting the first resistor R4, the second resistor R3, and the third resistor R2, the current can be limited, thereby protecting the first tipping switch U2 and the control switch tube Q1, and prolonging the service life of the tipping switch circuit 110.

[0061] In one exemplary embodiment, as Figure 3As shown, the tilt switch circuit 110 also includes a second tilt switch U1, which is disposed in the pet health companion device 200 and is connected to the coil of the relay K1.

[0062] The structure of the second tilt switch U1 is not limited, as long as it can achieve tilt detection. For example, the second tilt switch U1 can be a mechanical tilt detection switch, an electronic tilt detection switch, or other types. Mechanical and electronic switches include ball-type tilt detection switches and mercury switches, etc. Electronic tilt detection switches include photoelectric tilt switches, accelerometer sensors, or gyroscope sensors, etc. Furthermore, the first tilt switch U2 and the second tilt switch U1 can be of the same type, so that the tilt detection results of the pet health companion device 200 are the same, which also helps to reduce the structural design difficulty of the tilt protection device.

[0063] The second tilt switch U1 can be connected to the end of the coil of relay K1 that is not connected to the control switch Q1. Since the conduction state of control switch Q1 is determined by the tilt detection result of the first tilt switch U2, by setting the second tilt switch U1, the energization / de-energization state of the relay K1 coil can be determined jointly by the detection results of the first and second tilt switches U2. For example, when both the first and second tilt switches U2 detect that the pet health companion device 200 has tilted, the coil of relay K1 is energized, causing the normally closed contact of relay K1 to open, disconnecting the load from the live wire, de-energizing the load, and stopping its operation.

[0064] In this embodiment, the tilt switch circuit 110 further includes a second tilt switch U1, which is disposed in the pet health companion device 200 and connected to the coil of the relay K1. The second tilt switch U1 provides redundancy for the tilt detection device, effectively reducing the possibility of false triggering of the tilt protection.

[0065] In one exemplary embodiment, such as Figure 3 As shown, the tilt switch circuit 110 also includes a battery B1. The second tilt switch U1 is a photoelectric tilt switch. The battery B1 is connected to the primary terminal of the second tilt switch U1, and the secondary terminal of the second tilt switch U1 is connected to the coil of the relay K1.

[0066] Among them, the second tilt switch U1 is a photoelectric tilt switch. The photoelectric tilt switch uses a photoelectric sensor to detect changes in the position of the internal baffle or ball to detect the tilting state. The photoelectric tilt switch has a long life and good anti-vibration interference capability, and is suitable for high-precision or frequent triggering scenarios.

[0067] When the second tipping switch U1 is a photoelectric tipping switch, the photoelectric tipping switch includes a light-emitting diode and a secondary-end triode, the primary end of the second tipping switch U1 is at the side where the light-emitting diode is located, and the secondary end of the second tipping switch U1 is at the side where the secondary-end triode is located.

[0068] The primary end of the second tipping switch U1 is connected to the battery B1, and the battery B1 can provide power for the second tipping switch U1 to work normally. In addition, the battery B1 can also serve as a power supply to connect devices that need power, such as the common end of the first tipping switch U2, the second resistor R3, and the third resistor R2, and the first end of the control switch tube Q1, so that the tipping protection circuit can work normally. It can be understood that in the primary end of the second tipping switch U1, the end not connected to the battery B1 is grounded. The battery B1 can be a button cell, and the parameters of the button cell are determined according to the parameters of the second tipping switch U1.

[0069] The secondary end of the second tipping switch U1 is connected to the coil of the relay K1. It can be understood that in the secondary end of the second tipping switch U1, the end not connected to the relay K1 is grounded. When the pet health companion device 200 is tipped, the light-emitting diode of the primary end of the first tipping switch U2 and the second tipping switch U1 is unblocked, causing the secondary-end triode of the first tipping switch U2 to conduct, the control switch tube Q1 to conduct, and the secondary-end triode of the second tipping switch U1 to conduct, so that the coil of the relay K1 is powered, the normally closed contact of the relay K1 is actuated to open, the connection between the load and the live wire is disconnected, the load loses power, stops working, and the pet health companion device 200 stops running, achieving tipping protection for the pet health companion device 200.

[0070] In this embodiment, the tipping switch circuit 110 further includes a battery B1, the second tipping switch U1 is a photoelectric tipping switch, the battery B1 is connected to the primary end of the second tipping switch U1, and the secondary end of the second tipping switch U1 is connected to the coil of the relay K1. As the second tipping switch U1, the photoelectric tipping switch has the advantages of long service life, good anti-vibration interference ability, and is suitable for high-precision tipping detection or frequent tipping triggering use scenarios. The battery B1 can provide power, which is conducive to making the tipping switch circuit 110 work normally.

[0071] In an extendable embodiment, as shown in Figure 3 the tipping switch circuit 110 further includes a fourth resistor R1, and the battery B1 is connected to the primary end of the second tipping switch U1 through the fourth resistor R1. The fourth resistor R1 can act as a current-limiting resistor to limit the current flowing from the battery B1 to the primary end of the second tipping switch U1, thereby protecting the second tipping switch U1. It can be understood that in the primary end of the second tipping switch U1, the end not connected to the fourth resistor R1 is grounded.

[0072] In an extendable embodiment, as shown inFigure 3 As shown, the pour switch circuit 110 further comprises a freewheeling diode D1 connected to the coil of the relay K1. The connection of the freewheeling diode D1 to the coil of the relay K1 is not unique. Exemplarily, when the pour switch circuit 110 comprises the first pour switch U2, the second pour switch U1, the control switch Q1 and the relay K1 arranged in the pet health companion device 200, the anode of the freewheeling diode D1 is connected to one end of the coil of the relay K1 connected to the second pour switch U1, and further connected to one end of the secondary side of the second pour switch U1, and the cathode of the freewheeling diode D1 is connected to one end of the coil of the relay K1 connected to the second end of the control switch Q1.

[0073] In the embodiment, the pour switch circuit 110 further comprises a freewheeling diode D1 connected to the coil of the relay K1. The freewheeling diode D1 can discharge the current of the coil of the relay K1, so that the breaking of the contact of the relay K1 is more secure.

[0074] The structure of the contact feedback device 124 is also not unique. In an exemplary embodiment, the contact feedback device 124 comprises a mechanical contact circuit and a controller, the mechanical contact circuit is connected to the mechanical contact 122 and the controller; the mechanical contact circuit is in different conduction states based on the release or pressed state of the mechanical contact 122, and the controller controls the working state of the load according to the conduction state of the mechanical contact circuit.

[0075] The mechanical contact circuit is connected to the mechanical contact 122 and is in different conduction states based on the release or pressed state of the mechanical contact 122. Based on the structure of the mechanical contact circuit, the correspondence between the conduction state of the mechanical contact circuit and the release or pressed state of the mechanical contact 122 includes two possible cases: in the first case, when the mechanical contact 122 is released, the mechanical contact circuit is in the conduction state, and when the mechanical contact 122 is pressed, the mechanical contact circuit is in the off state. In the second case, when the mechanical contact 122 is released, the mechanical contact circuit is in the off state, and when the mechanical contact 122 is pressed, the mechanical contact circuit is in the conduction state. The working state of the load can include working or not working of the load.

[0076] The mechanical contact circuit is also connected to a controller, and the controller controls the working state of the load according to the conduction state of the mechanical contact circuit. Since the conduction state of the mechanical contact circuit is determined based on the release or pressing state of the mechanical contact 122, and the release or pressing state of the mechanical contact 122 is determined based on the tipping state of the pet health companion device 200, the controller can control the working state of the load according to the tipping state of the pet health companion device 200, and control the load to not work when the pet health companion device 200 tips over, so that the pet health companion device 200 stops running, and the safety hazard caused by the pet health companion device 200 continuing to run when it tips over is avoided.

[0077] In this embodiment, the contact feedback device 124 includes a mechanical contact circuit and a controller, the mechanical contact circuit is connected to the mechanical contact 122 and the controller, and the controller controls the working state of the load according to the conduction state of the mechanical contact circuit. Thus, based on the feedback of the release or pressing state of the mechanical contact 122 by the mechanical contact circuit, the controller can control the working state of the load according to the tipping state of the pet health companion device 200, and control the load to not work when the pet health companion device 200 tips over, so that the pet health companion device 200 stops running, and the running safety of the pet health companion device 200 is improved.

[0078] In one exemplary embodiment, as shown in Figure 4 The mechanical contact circuit includes a pin seat CN1, a first end of the pin seat CN1 is connected to the controller (may be connected to the MCU_IO pin of the controller) and a power supply, the voltage of the power supply can be +5V, a second end of the pin seat CN1 is grounded, and the pin seat CN1 is in different conduction states based on the release or pressing state of the mechanical contact 122.

[0079] The pin seat CN1 is connected to the mechanical contact 122. The pin seat CN1 is in different conduction states based on the release or pressing state of the mechanical contact 122. Based on the different structures of the pin seat CN1, there are two possible cases of the correspondence between the conduction state of the pin seat CN1 and the release or pressing state of the mechanical contact 122: in the first case, when the mechanical contact 122 is pressed, the first end and the second end of the pin seat CN1 are not conductive, and when the mechanical contact 122 is released, the first end and the second end of the pin seat CN1 are conductive. In the second case, when the mechanical contact 122 is pressed, the first end and the second end of the pin seat CN1 are conductive, and when the mechanical contact 122 is released, the first end and the second end of the pin seat CN1 are not conductive.

[0080] The first end of the needle seat CN1 is connected with the controller and the power supply, and the second end of the needle seat CN1 is grounded. When the first end and the second end of the needle seat CN1 are conducted, the controller receives a low level. When the first end and the second end of the needle seat CN1 are not conducted, the controller receives a high level. The controller controls the working state of the load according to the received high and low levels, and the control process is simple.

[0081] In the embodiment, the mechanical contact circuit includes a needle seat CN1, the first end of the needle seat CN1 is connected with the controller and the power supply, and the second end of the needle seat CN1 is grounded. The needle seat CN1 is in different conduction states based on the release or pressed state of the mechanical contact 122. Based on the structure and connection relationship of the needle seat CN1, when the mechanical contact 122 is in the release or pressed state according to the tilting state of the pet health accompanying device 200, the conduction state of the needle seat CN1 is different, and the controller can receive different level signals, which is convenient for controlling the load to protect the pet health accompanying device 200 from tilting.

[0082] In an exemplary embodiment, as shown in Figure 4 The mechanical contact circuit further includes a fifth resistor R5, a sixth resistor R6 and a capacitor C1. The first end of the needle seat CN1 is connected with the power supply through the fifth resistor R5, and is connected with the controller through the sixth resistor R6. The capacitor C1 is connected in parallel with the needle seat CN1.

[0083] The fifth resistor R5 and the sixth resistor R6 can both be used as current limiting resistors to limit the current size.

[0084] The first end of the needle seat CN1 is connected with the power supply through the fifth resistor R5, which can limit the current flowing to the needle seat CN1 and protect the needle seat CN1. The first end of the needle seat CN1 is connected with the controller through the sixth resistor R6, which can limit the current flowing to the controller and protect the controller. The capacitor C1 is connected across the two ends of the needle seat CN1, and can be used as a filter capacitor C1 to prevent abnormal level interference and improve the working performance of the mechanical contact circuit.

[0085] In the embodiment, the mechanical contact circuit further includes a fifth resistor R5, a sixth resistor R6 and a capacitor C1. The first end of the needle seat CN1 is connected with the power supply through the fifth resistor R5, and is connected with the controller through the sixth resistor R6. The capacitor C1 is connected in parallel with the needle seat CN1. The fifth resistor R5 and the sixth resistor R6 can protect the controller and the needle seat CN1, and the capacitor C1 can filter out noise to improve the working performance of the mechanical contact circuit.

[0086] The pet health accompanying device 200 can include a device beneficial to pet health, or a device that can accompany a pet, or a device that can both be beneficial to pet health and accompany a pet. Illustratively, the pet health accompanying device 200 can be a pet purifier, or can be a pet toy, or can be a device integrating a pet toy and a purifier.

[0087] In order to better understand the above-mentioned embodiments, the following will be explained in detail in combination with a specific embodiment. In one embodiment, as shown in Figure 5 The pet health accompanying device 200 includes a tipping protection device, an operation panel, a display panel, a pet teasing module, a pet nest, an air outlet, an air inlet, and a moving assembly. As shown in Figures 1-4 The tipping protection device includes a tipping switch circuit 110, a mechanical contact 122, and a contact feedback device 124. The tipping switch circuit 110 includes a first tipping switch U2, a second tipping switch U1, a control switch tube Q1, a relay K1, a first resistor R4, a second resistor R3, a third resistor R2, a fourth resistor R1, a battery B1, and a freewheeling diode D1. The contact feedback device 124 includes a mechanical contact circuit and a controller. The mechanical contact circuit includes a needle seat CN1, a fifth resistor R5, a sixth resistor R6, and a capacitor C1. The first tipping switch U2 and the second tipping switch U1 are ball-type photoelectric switches, the control switch tube Q1 is a PNP triode, and the battery B1 is a button cell. In the figure, MCU IO connects the pin of the controller, and the controller can receive high and low levels through this pin. The needle seat CN1 is connected with the mechanical contact 122. When the whole machine is not tipped, the mechanical contact 122 is pressed down, and the needle seat CN1 is turned on. When the whole machine is tipped, the mechanical contact 122 is released, and the needle seat CN1 is not turned on.

[0088] The working process of the pet health accompanying device 200 is as shown in Figure 6 First, the whole machine is powered on, and the whole machine is tipped. If U1, U2, and the mechanical contact 122 are faulty, ① as shown in Figure 3 the circuit. After tipping, if U2 is internally faulty, the original end light-emitting diode is not removed from the blockage, the secondary end triode is not turned on, the base of the triode is pulled to VCC, the triode Q1 is not turned on, the relay K1 K1 is not powered, the normally closed switch is not actuated, the live wire (AC_L) is still connected to the subsequent load (AC_L2), the whole machine works normally, and the tipping protection function is not achieved. If U1 is internally faulty, the original end light-emitting diode is not removed from the blockage, the secondary end triode is not turned on, and the relay K1 K1 coil is not powered, and the tipping protection function is not achieved. ② The whole machine is tipped, and the mechanical contact 122 is faulty and not popped up, as shown in Figure 4, CN1 is not connected, MUC IO is connected to +5V (high level), the controller receives a high level signal, and the load is not controlled to be turned off, and the dump protection function is not achieved.

[0089] If U1, U2 and the mechanical contact 122 are not faulty, ① as shown in Figure 3 The circuit, after dumping, as shown in U2, the original end light emitting diode is unblocked, causing the secondary end triode to conduct, causing the base of the triode Q1 to be pulled to GND, so that the triode Q1 conducts, and in U1, the original end light emitting diode is unblocked, causing the secondary end triode to conduct, so that the relay K1 K1 coil is energized, the normally closed switch is opened, the live wire (AC_L) is disconnected, and the whole machine is powered off, achieving the dump protection function; ② the whole machine is dumped, and the mechanical contact 122 is popped up, as shown in Figure 4 , CN1 is connected, MUC IO is pulled to GND, and the chip receives a low level signal, and the load is completely turned off, achieving the dump protection function. The dump switch circuit 110 serves as the first dump protection structure, and the mechanical contact 122 and the contact feedback device 124 serve as the second dump protection structure. Through the two dump protection structures, even if one fails, the other can still provide protection, greatly improving the success probability of dump protection. In addition, the use of dual dump protection method can ensure that the pet health companion robot is completely powered off and automatically stopped running, providing protection effect, preventing damage due to dumping or causing danger to pets, and improving user experience.
