     Dogs also often urinate and defecate adjacent to automobile tires. After dogs urinate and defecate at the tires, the smell is unpleasant, and the acid contained in the excrement will corrode the tires, which not only causes troubles to the automobile owner but also poses a safety hazard. 
     In order to prevent dogs and other pets from urinating and defecating at car tires, car owners have taken many measures, for example, spraying agents on the tires regularly for repelling animals. However, the agent for repelling animals requires users to spray manually. Moreover, due to strong volatility, the agent sprayed on the tires would disappear quickly with wind, rain, car washing or the like. 
     In addition to the tires mentioned above, animals such as pets are not expected to appear or step in gardens or waterscape in neighborhoods. In order to prevent the animals from appearing in such places, users often spray the agents for repelling animals or put drugs for repelling animals in an open space, and have to observe the degree of vaporization of the drugs from time to time. However, they cannot find in time that the drugs have vaporized totally. 
       FIG. 1  is a perspective view illustrating an animal repelling device in accordance with some embodiments of the present disclosure.  FIG. 2  is a structural block diagram illustrating a monitoring system of the animal repelling device in accordance with some embodiments of the present disclosure.  FIG. 3  is an exploded view of the animal repelling device in accordance with some embodiments of the present disclosure. 
     Referring to  FIGS. 1, 2 and 3 , the exemplary embodiment of the present disclosure provides an animal repelling device  10  including a container  101 , an end cap  102 , one or more liquid level sensors  104  and a wireless communication component  109 . 
     An opening is formed at one end of the container  101 , and a liquid storage space is formed in the container  101 . The end cap  102  includes a top plate and a side wall surrounding the opening, and through holes  103  are formed on the side wall or the top plate. The one or more liquid level sensors  104  are disposed in the container  101 , at a position proximal to the bottom of the container  101 . The wireless communication component  109  is disposed on the container  101  and configured to receive a liquid level signal sent by the liquid level sensor  104 . 
     The through holes  103  may be provided on a circumferential side surface of the end cap  102  or a top surface of the end cap  102 . 
     The above structure constitutes the animal repelling device  10  provided by the present disclosure. Volatile liquid is stored in the liquid storage space in the container  101  and can volatilize to the outside of the container  101  via through holes on the end cap  102 . In the present embodiment, a plurality of through holes  103  are formed on the side wall or the top plate of the end cap  102  to improve the vaporization effect of liquid to the outside of the device. The liquid level in the container  101  is sensed by the liquid level sensor  104 . when volatile liquid is insufficient (namely, the liquid level is lower than the position of the liquid level sensor  104 ), the wireless communication component  109  is adopted to control the liquid to stop vaporization to the outside of the container  101 . 
     The above animal repelling device has the function of effectively repelling animals by injecting the volatile liquid for repelling animals in the container  101 , and can automatically detect the remaining amount of the volatile liquid by arrangement of the liquid level sensor  104  so as to replenish the volatile liquid in time. The animal repelling device can intelligently control the vaporization of drugs for repelling animals, and automatically monitor the remaining amount of the drugs for repelling animals so as to replenish the volatile liquid drugs in time. 
     Vaporization of the volatile liquid can be accelerated as the temperature rises. 
     By utilization of this characteristic, the liquid can be heated to increase the speed of liquid vaporization. 
     In some embodiments, the animal repelling device further includes a heater  105  and a power supply  106 . The heater  105  is disposed in the container  101 . The power supply  106  is electrically connected with the heater  105 . The heater  105  operates according to a heater-operating instruction for the heater  105  received by the wireless communication component  109 . 
     The heater  105  disposed in the container  101  generates heat by the power supply  106  to heat the volatile liquid, so as to increase the speed of liquid vaporization. The ON/OFF of the power supply  106  may be controlled by the wireless communication component  109 . 
     The power supply  106  may be batteries and the like. Considering that batteries have to be changed in time if used up and that the volume and weight of the animal repelling device are increased with complicated structure due to the batteries, natural resources are utilized in the present disclosure to convert into electrical energy so as to avoid resource waste. 
     In some embodiments, the power supply  106  is a solar-energy photo-voltaic power supply disposed at an outer surface of the side wall or the top plate of the end cover  102 . 
     The conversion of solar energy into electrical energy can avoid resource waste, effectively utilize natural resources, simplify the device structure, and save the cost. In the process of using the animal repelling device, the end cap  102  must be kept in an orientation on the upper portion of the device to prevent the liquid from flowing out via the through holes  103 . Thus, the solar-energy photo-voltaic power supply is arranged on the outer surface of the side wall or the top plate of the end cap  102  such that the solar energy can be fully received, improving the power-generating efficiency of the solar energy. In the present embodiment, in order to improve the power-generating efficiency of the solar energy, the solar-energy photo-voltaic power supply is disposed on the top plate of the end cap  102 . 
     The heater  105  may be a widely used device in various devices. Various types of heaters  105  may be adopted according to different use objectives and heating degrees. In the animal repelling device of the present disclosure, there is no need for volatile liquid to use complicated and large-scale heater since the vaporization efficiency can be greatly improved by slight increasing the temperature of the liquid. 
     In some embodiments, the heater  105  is a heating rod with one end connected with the end cap  102  and the other end extending towards the bottom in the container. 
     The heat generated by the heating rod after electrified is enough to increase temperature of the liquid to accelerate the vaporization, with simple structure and low cost. Since one end of the heating rod is connected with the end cap  102 , and the other end is proximal to the bottom of the container  101 , liquid waste is reduced and liquid temperature is uniform from top to bottom. When the liquid is heated by the heating rod, the liquid is required at least contact the bottom of the heating rod, so as to avoid the dry burning or even burnout of the heating rod. Thus, the liquid must always contact the heating rod. On one hand, in order to ensure the full utilization of the liquid, the bottom of the heating rod must be proximal to the bottom of the container  101  as much as possible. On the other hand, in order to ensure that the liquid always contacts the bottom of the heating rod, the liquid level sensor  104  is not lower than the bottom of the heating rod. 
     In some embodiments, the liquid level sensor (first liquid level sensor)  104  is disposed at one end of the heating rod proximal to the bottom of the container  101 . 
     As described above, the liquid level sensor  104  is disposed at the bottom of the heating rod, which effectively realizes that the liquid level is always in contact with the heating rod to avoid the dry burning of the heating rod. 
     When the animal repelling device is used, there are various mounting orientation, such as horizontal orientation. At this point, although most of the liquid is vaporized, the bottom of the heating rod still contacts the liquid such that the remaining amount of the liquid cannot be accurately detected. 
     In some embodiments, a second liquid level sensor is further disposed on a circumferential surface of the heating rod. 
     In the present embodiment, in order to ensure that information about the liquid volume is accurately detected, the liquid level sensor is further disposed on the circumferential surface of the heating rod. A plurality of second liquid level sensors may be disposed on the circumferential surface of the heating rod according to the circumference diameter of the heating rod and other factors. For instance, three liquid level sensors are uniformly distributed along the circumferential direction of the heating rod. 
     The vaporization efficiency of the liquid can be improved by using the heating rod, but enough electrical energy must be guaranteed to be provided to the heating rod for heating. When the power supply  106  cannot provide power due to certain reason, the power supply  106  must be cut off in time, so that the user can take corresponding measures. 
     The volatile liquid injected into the container  101  can volatilize to the outside of the container  101  to repel animals around. The heating rod is adopted to heat the volatile liquid to accelerate the vaporization and enhance the effect of repelling animals. However, in this way, once upon the volatile liquid is injected into the container, the animal repelling device always volatilizes the liquid to the outside of the container  101 , even in the case that animals cannot approach, such as during the traveling of a vehicle. Hence, the waste of the liquid is caused. 
     In some embodiments, the animal repelling device further includes a valve  108  disposed between the through holes  103  and the opening of the container  101 . 
     By arrangement of the valve  108 , the liquid is saved and the waste is reduced since the valve  108  can be closed when not repelling animals. For both the opening and closing of the valve  108  and the heating operation of the heating rod, it is necessary to ensure sufficient power capacity in the power supply  106 . 
     In some embodiments, the animal repelling device further includes a power sensor  107  configured to send a power supply capacity signal to the wireless communication component  109 . 
     Since the power supply capacity can be detected by the power sensor  107 , when the power supply capacity is less than the predetermined threshold, the power supply  106  is controlled to be cut off. In the present disclosure, as described above, a solar battery is adopted as the power supply  106 . When the power supply  106  cannot provide power for the heating rod due to failure or other reasons, the power sensor  107  transmits a signal of insufficient power supply capacity to the wireless communication component  109 , and the wireless communication component  109  controls the power supply  106  to be cut off. 
     The animal repelling device with the above structure enables users to easily implement automatic control at the scene, but cannot achieve remote control. 
     In some embodiments, the animal repelling device further includes a control terminal  300  configured to control the opening and closing of the valve  108  and the heating of the heater based on the wireless communication component  109 . 
     The control terminal  300  transmits information with the wireless communication component  109  remotely through wireless communication, and receives status information, including level information, power supply capacity information, etc., of the animal repelling device through the wireless communication component  109 . Moreover, the control terminal  300  sends a control instruction, such as a power supply on/off instruction and a valve opening/closing instruction, to the wireless communication component  109 . The control terminal  300  may be a mobile terminal such as a notebook computer, a tablet or a mobile phone. Taking the mobile phone as an example, a control program is installed on the mobile phone, and the animal repelling device is monitored in the control program. When an alarm signal is received by the mobile phone, the user can be notified through common alarm approaches such as text notification, audible alarm, and indicator light flashing, which greatly facilitates the user&#39;s remote control of the animal repelling device. 
     The animal repelling device does not need too much volume as long as the liquid vaporization speed is sufficient to repel the animals, since the opening size of the valve  108  can be controlled to save the volatile liquid. Therefore, the container  101  can adopt a small container, but it might be not stable enough. 
       FIGS. 4A, 4B, and 4C  are perspective views illustrating connectors of the animal repelling device in accordance with some embodiments of the present disclosure.  FIG. 4A  is a perspective view of a suction connector of the animal repelling device in accordance with some embodiments of the present disclosure.  FIG. 4B  is a perspective view illustrating a reducing joint adapter connector of the animal repelling device in accordance with some embodiments of the present disclosure.  FIG. 4C  is a perspective view illustrating a bracket connector of the animal repelling device in accordance with some embodiments of the present disclosure.  FIG. 5  is an exploded view of the animal repelling device in accordance with some embodiments of the present disclosure. 
     In some embodiments, referring to  FIGS. 4A, 4B, 4C, and 5 , the animal repelling device further includes a fixing structure  500  configured to fix the animal repelling device. 
     The stability of the animal repelling device can be increased by the fixing structure  500 . The fixing structure  500  has multiple fixing modes. Different fixing modes may be selected according to actual conditions. 
     In some embodiments, the fixing structure  500  includes an internal threaded hole portion  510  extending from the bottom of the container  101  in a direction distal from the end cap  102 . 
     At a place provided with a screw, the animal repelling device is fixed by the engagement between threaded hole and the screw, since the internal threaded hole portion  510  is arranged at the bottom of the container. For instance, the animal repelling device is fixed at an air inlet of a wheel through the engagement between the threaded hole of the threaded hole portion  510  and external threads of the air inlet. Other accessories may be adopted for connection in other places or when the size of the screw does not match the threaded hole. 
     In some embodiments, referring to  FIGS. 4A, 4B and 4C , the fixing structure  500  further includes a connector  520  which is a suction connector, a reducing joint adapter connector or a bracket connector. The suction connector, the reducing joint adapter connector or the bracket connector is connected with the container  101  through the internal threaded hole portion  510 . 
     The suction connector includes a stud  521  and a suction cup  522  connected with each other. The stud  521  is engaged with the threaded hole portion  510 . The suction cup  522  is configured to adsorb the animal repelling device on a smooth plane such as marble floor, wall, etc. 
     The reducing joint adapter connector includes a stud  521  and a reducing portion  523 . The reducing portion  523  may be an internal threaded hole or an external thread stud. The stud  521  is engaged with the threaded hole portion  510 . Threads of the reducing portion  523  are engaged with threads at a fixing position. 
     The bracket connector includes a stud  521  and a bracket  524  connected with each other. The stud  521  is engaged with the threaded hole portion  510 . The bracket  524  is configured to support the animal repelling device on the ground or insert the animal repelling device into the soil. The bracket includes at least two legs  5241 . No matter the animal repelling device is supported on the ground or inserted in the soil, three legs  5241  can stably support the animal repelling container. In addition, a clamp connector may also be adopted. One clamping band may be connected below the stud  521  to fix on a tube. No further description will be given herein. By the above fixing modes, the animal repelling device can be fixed in different orientations and is applicable to various cases. In order to avoid the liquid from flowing out of the container  101 , the end cap  102  must be kept upwards as much as possible while fixing the animal repelling device. For instance, if fixed on a wheel, the animal repelling device may be fixed on an air inlet of the wheel through the threaded hole portion  510  of the fixing structure  500  and the reducing joint adapter connector. 
     In order to prevent the liquid from flowing out of the container  101 , the container  101  may be rotatably fixed on a hub or an axle of the wheel (herein, “rotatably” means the container  101  would rotate relative to hub or an axle of the wheel but not rotate together with the wheel and the hub thereof). 
       FIG. 5  is an exploded view illustrating the animal repelling device in accordance with some embodiments of the present disclosure. 
     In some embodiments, the attaching structure  200  includes a bolt  220  and a connecting member  210 . The bolt  220  includes a nut  221 , a polished rod  222  and a screw rod  223  sequentially connected. The screw rod  223  is engaged with a threaded hole on an end surface of the hub or the axle of the car wheel. One end of the connecting member  210  is fixed on the end cap  102 , and the other end of the connecting member  210  is provided with a circular ring. The outside diameter of the screw rod  223  is less than the outside diameter of the polished rod  222 , and the outside diameter of the polished rod  222  is less than the inside diameter of the circular ring. 
     The attaching structure  200  with the above structure is simplified and convenient to install. As the outside diameter of the screw rod  223  is less than the outside diameter of the polished rod  222 , the screw rod  223  can be completely screwed into a threaded hole to realize good connection between the screw rod  223  and the hub or the axle of the wheel. As the inside diameter of the circular ring is greater than the outside diameter of the polished rod  222 , the animal repelling device is mounted around an axle center of the bolt  220  in a free rotation mode (herein, “in a free rotation mode” means that the container of the device would rotate relative to the bolt  220  but not rotate together with the bolt  220  and hub or the axle of the wheel), such that the end cap  102  is always oriented on the upper portion of the animal repelling device to prevent the liquid from flowing out. In the embodiment, the screw rod  223  may be fixed on the center of the wheel axle, so as to effectively avoid the liquid be thrown out of the device due to centrifugal force during moving of the car. 
     Animals such as cats and dogs often urinate and defecate on the tires of car parking. In the driving process, animals cannot urinate and defecate. Thus, the animal repelling device provided by the present disclosure begins to volatilize the liquid when the car is parked, so the animal repelling device may be placed near the wheel. But if the animal repelling device is not fixed, the driver has to put the animal repelling device after parking and get it back before moving the car. It is troublesome and brings inconvenience to the driver. Therefore, the animal repelling device can be connected with the wheel. No matter the car is parked or moving, no manual setting operation is required for the animal repelling device. However, wheels are rotating during driving, and every point on the wheel when parked is in different orientation each time. Therefore, in order to ensure that the liquid does not flow out of the device, the animal repelling device must be arranged to orient the end cap  102  on the upper portion of the device. 
     The animal repelling device can be fixed on the hub or the axle of the wheel via the attaching structure  200 , so as to reduce the operation of the driver in arranging the animal repelling device and improve the user experience. The animal repelling device is mounted on the hub or the axle of the wheel in a free rotation mode, so as to avoid the liquid from flowing out via the through holes and the like. There are multiple specific rotatable connection modes between the animal repelling device and the hub or the axle. No complicated fixing/attaching structure is required, thereby reducing the cost, simplifying manufacturing process with convenient installation. 
     The animal repelling device is mounted on the wheel. When the car is parked, the valve  108  is opened, so that the liquid can volatilize to repel animals. In the driving process of the car, the valve  108  is closed to save the liquid since animals cannot urinate and defecate. 
     In some embodiments, the wireless communication component  109  receives an instruction sent by a vehicle controller  400 . 
     After the car is started, the vehicle controller  400  sends a closing instruction to the valve  108  through the wireless communication component  109 , and sends a power off instruction to the power supply  106 , so that the valve  108  is automatically closed and the power supply  106  is automatically cut off. Thus, it is advantageous to save the liquid, reduce the manual operations with improved user experience. 
       FIG. 6  is a flowchart illustrating an animal repelling method in accordance with some embodiments of the present disclosure. 
     Referring to  FIG. 6 , according to another aspect of the present disclosure, there is provided an animal repelling method being applied to an animal repelling device including a valve and a heater immersed into a volatile liquid for repelling animals. The method comprises: 
     S 100 : receiving an opening instruction sent by a control terminal wirelessly connected with the animal repelling device. 
     S 200 : opening the valve of the animal repelling device according to the opening instruction, and turning on the heater of the animal repelling device. 
     The volatile liquid for repelling animals can be injected into the container to repel the animals through the vaporization of the liquid. In order to improve the vaporization of the liquid and enhance the stimulation on the animals, the vaporization speed of the liquid is increased by the heating operation of the heating rod. When the liquid is reduced such that the liquid level reaches the bottom of the heating rod, in order to avoid the damage of the heating rod due to the dry burning of the heating rod, liquid level information is transmitted to the control terminal through the liquid level sensor, then the control terminal sends a power off signal to the power supply through the wireless communication component after receiving the signal that the liquid level is at the bottom of the heating rod such that the power supply is cut off. After the user injects the volatile liquid for repelling animals into the animal repelling device and the power supply is powered on again, the animal repelling device works normally again. 
     In the embodiment, the control terminal may be a mobile terminal such as a mobile phone or a remote controller. 
     The animal repelling method for the car provided by the present disclosure effectively has the function of repelling animals by injecting the volatile liquid with pungent odor on animals into the container, and can automatically monitor the insufficiency of the volatile liquid by the liquid level sensor transmitting the liquid level information to the control terminal, so as to replenish the volatile liquid in time 
     In some embodiments, the animal repelling device also includes a liquid level sensor. The method further includes allowing the wireless communication component to control the cut-off of the power supply when the liquid level sensor detects that the liquid level is lower than the predetermined level. When the liquid level is lower than the predetermined level, it indicates that the liquid in the container tends to be completely vaporized, the animal repelling device need to turn off the heater while reminding the user replenishes the volatile liquid for repelling animals in the container in time. 
     In some embodiments, the method further includes sending information that the liquid level is lower than the predetermined level to the control terminal, to remind the user to replenish the liquid in time. The wireless communication component and the control terminal are in wireless communication. The wireless communication component sends information about the liquid remaining volume in the container to the control terminal at any time. When insufficient liquid volume is detected, the control terminal sends out notification information to notify the user to replenish the liquid in time, thereby realizing the remote monitoring of the animal repelling device. 
     In some embodiments, the method further includes sending capacity reminding information that the power supply capacity is lower than the predetermined threshold to the control terminal when a power sensor of the animal repelling device detects that the power supply capacity is lower than a predetermined threshold, to remind the user to replace batteries or charge in time. The wireless communication component and the control terminal are in wireless communication. The wireless communication component sends the capacity reminding information of the power supply to the control terminal at any time. When insufficient power supply capacity is detected, the control terminal sends notification information to notify the user to replace the power supply, namely the end cap, in time, or take measures such as maintenance on the power supply, thereby realizing the remote monitoring of the animal repelling device. The battery may be a solar battery, a dry battery, or a rechargeable battery, etc. 
     In some embodiments, the control terminal sends a power supply on/off instruction and a valve opening/closing instruction to the wireless communication component, realizing the initiative remote control of the user on the valve and the power supply. For instance, when the car enters the garage and there is no animal in the garage, if the animal repelling device still works to volatilize the liquid, the liquid will be wasted. Accordingly, the control terminal may be initiatively operated by users to close the valve and cut off the power supply. 
     In some embodiments, the vehicle controller of the car sends the operating status of an engine to the wireless communication component. When the operating status is off, the heater is turned on and the valve is opened. When the operating status is on, the heater is turned off and the valve is closed. 
     Animals might urinate and defecate on the wheels only when the car is parked. Therefore, in order to save the liquid, after starting the car or during the moving of the car, the vehicle controller sends the power off instruction and the valve closing instruction to the animal repelling device through the wireless communication component, such that the power supply is cut off and the valve is closed. 
     As such, the animal repelling method of the car provided by various embodiments of the present disclosure can effectively repel animals through the vaporization of the volatile liquid for repelling the animals when the car is parked, and effectively protect the heating rod from being burned out and remind users to replenish the liquid by cooperation the between liquid level sensor and the control terminal. 
     Hereinafter, the animal repelling method provided by various embodiments of the present disclosure is illustrated in an example of a car to repel animals and prevent the animals from urinating and defecating on the wheels of the car. 
     The user can inject the volatile liquid for repelling animals into the container, closes the end cap, and now the heating rod is inserted into the liquid, and the lower end portion is proximal to the bottom of the container. Then, put the bolt through the circular ring of the attaching structure of the animal repelling device for the car, the screw is partially screwed into the threaded hole on the axle center of the wheel Such that the animal repelling device is hung on the axle of the wheel. Next, open the valve, and power on the power supply. The volatile liquid is vaporized to the outside via the through holes on the side wall of the end cap by the heating rod. The animals are kept away from the wheels while smelling the irritant odor of the volatile gas, thereby effectively preventing the animals from urinating and defecating on the wheels. 
     The user can leave after mounting and starting the animal repelling device for the car. Along with the vaporization of the liquid, the liquid level sensor sends the liquid level information to the mobile phone through the wireless communication component at any time. A device monitoring application (APP) is installed on the mobile phone in advance. The user can check the liquid level information of the device at any time through the APP on the mobile phone. When the liquid level sensor detects that the liquid level has reached the bottom of the heating rod, the mobile phone gives an alarm and sends out notification information. Then, the user cuts off the power supply of the animal repelling device for the car through the APP, and the heating rod stops heating. The user can replenish the volatile liquid in the container, close the end cap and then switch on the power supply. 
     In the use process, the power sensor monitors the power supply capacity in real time and sends power supply capacity information to the mobile phone through the wireless communication component. When detecting that the power supply capacity tends to be exhausted, the mobile phone gives an alarm and sends out notification information. The user can cut off the power supply through the APP, check the power supply, and repairs or replaces the end cap. 
     In the use process, the user can cut off the power supply and close the valve through the APP according to conditions, for example, after the car enters the garage. 
     In the use process, when the user wants to drive away and start the car, the vehicle controller automatically sends a closing instruction to the valve and sends a power off instruction to the power supply, through the wireless communication component Such that the valve is closed and the power supply is cut off. When the car arrives at the destination and is parked, the user gets off the car and opens the valve and switches on the power supply through the APP on the mobile phone.
