Description

Technical Field

[0001] The utility model relates to the field of wireless charging, and in particular to a wireless charging device and an intelligent toilet. Background Art

[0002] Currently, smart toilets on the market often come with a remote control. Users operate the remote's buttons to activate the toilet's functions or adjust its settings. To ensure operation in humid environments, remote controls are typically sealed. Some models use replaceable conventional batteries, while others utilize a built-in lithium battery powered by wireless charging.

[0003] Smart toilet remote controls that use replaceable conventional batteries, such as AA and AAA alkaline batteries, require a battery cover with a sealing gasket, making disassembly and assembly difficult, typically requiring tools like a screwdriver. This product offers a lower cost but a poorer user experience.

[0004] Using a wireless charging remote control with a built-in lithium battery and a corresponding wireless charging base eliminates the hassle of replacing batteries. However, to ensure charging efficiency, the remote control must be accurately placed in the charging position of the base. This requires corresponding positioning structures on the base and remote control. Although the positioning structures can form a fixed position to maintain the remote control in a stable position, they need to be aligned with the positioning structures when placing the remote control, which is not convenient. In addition, the remote control and wireless charging base require position detection using logic control devices such as microprocessors, which increases product costs. Utility Model Content

[0013] Wherein, when the transmitting induction coil and the receiving induction coil both start to work, the receiving power supply starts to charge.

[0019] The receiving electromagnetic switch and the emitting magnetic member are configured such that when the distance between the first surface and the second surface is smaller than a set value, the receiving electromagnetic switch can sense the magnetic field of the emitting magnetic member and be turned on.

[0020] In some embodiments of the present application, the set value is 1 mm.

[0021] In some embodiments of the present application, the first surface and the second surface are both planes.

[0022] In some embodiments of the present application, the transmitting module further includes a transmitting power supply;

[0023] When the transmitting induction coil starts to work, the transmitting power supply provides electrical energy to the transmitting induction coil.

[0024] In some embodiments of the present application, the transmitting electromagnetic switch includes a transmitting switch element and a transmitting enabling element;

[0025] When the receiving magnetic member is aligned and magnetically attracted to the transmitting metal ring, the transmitting switch element senses the magnetic field of the receiving magnetic member and controls the transmitting enabling element to be turned on, so that the transmitting induction coil starts to work;

[0026] When the receiving magnetic member and the transmitting metal ring are misaligned, the transmitting switch element fails to sense the magnetic field of the receiving magnetic member and controls the transmitting enabling element to be turned off, so that the transmitting induction coil stops working;

[0027] The receiving electromagnetic switch includes a receiving switch element and a receiving enabling element;

[0028] When the transmitting magnetic member is aligned and magnetically attracted to the receiving metal ring, the receiving switch element senses the magnetic field of the transmitting magnetic member and controls the receiving enable element to be turned on, so that the receiving induction coil starts to work;

[0036] It can be seen from the above technical solutions that the embodiments of the present utility model have at least the following advantages and positive effects:

[0037] In the wireless charging device of this embodiment, when the receiving module is placed on the transmitting module, the magnetic attraction between the receiving magnetic member and the transmitting metal ring, as well as the magnetic attraction between the transmitting magnetic member and the receiving metal ring, can fine-tune the placement of the receiving module. This can generate a driving force to move the receiving module, if it is not positioned accurately, toward the correct position. Furthermore, the magnetic attraction maintains the position of the receiving module on the transmitting module, ensuring that the receiving module does not shift during charging, affecting charging efficiency.

[0038] Only when the receiving magnetic part is aligned and magnetically attracted to the transmitting metal ring, and the transmitting magnetic part is aligned and magnetically attracted to the receiving metal ring, that is, when the receiving module is accurately aligned with the transmitting module, will the transmitting induction coil and the receiving induction coil both start working and the receiving power supply starts charging. However, when the receiving magnetic part and the transmitting metal ring are misaligned, or the transmitting magnetic part and the receiving metal ring are misaligned, that is, when the receiving module is not accurately placed on the transmitting module, the receiving power supply cannot be charged. Therefore, this solution does not require the use of a control device with position detection to ensure that the receiving module and the transmitting module will only start charging when they are accurately aligned. It can achieve position determination at a low cost and is convenient for users to operate.

[0039] In addition, the transmitting electromagnetic switch is arranged on the inner side of the transmitting metal ring, and the receiving electromagnetic switch is arranged on the inner side of the receiving metal ring, which makes the structural arrangement more compact and is conducive to product miniaturization.

[0047] Thus, a feature indicated in this specification is intended to illustrate one of the features of one embodiment of the present invention, rather than implying that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features can be combined together to illustrate possible system designs, these features can also be used in other, not explicitly described, combinations. Thus, unless otherwise noted, the described combinations are not intended to be limiting.

[0048] See also Figure 1 and Figure 2 The utility model provides a wireless charging device, which includes a transmitting module 1 and a receiving module 2.

[0049] The transmitting module 1 includes a transmitting magnetic member 11 , a transmitting metal ring 12 , a transmitting electromagnetic switch 13 and a transmitting induction coil 14 . The transmitting electromagnetic switch 13 is arranged inside the transmitting metal ring 12 .

[0050] The receiving module 2 includes a receiving magnetic member 21 , a receiving metal ring 22 , a receiving electromagnetic switch 23 , a receiving induction coil 24 and a receiving power supply. The receiving electromagnetic switch 23 is arranged inside the receiving metal ring 22 .

[0051] When the receiving magnetic member 21 is aligned and magnetically attracted to the transmitting metal ring 12, the transmitting electromagnetic switch 13 senses the magnetic field of the receiving magnetic member 21 and turns on, thereby starting the transmitting induction coil 14. When the receiving magnetic member 21 and the transmitting metal ring 12 are misaligned, the transmitting electromagnetic switch 13 turns off, thereby stopping the transmitting induction coil 14.

[0052] When the transmitting magnetic member 11 is aligned and magnetically attracted to the receiving metal ring 22, the receiving electromagnetic switch 23 senses the magnetic field of the transmitting magnetic member 11 and turns on, thereby starting the receiving induction coil 24. When the transmitting magnetic member 11 and the receiving metal ring 22 are misaligned, the receiving electromagnetic switch 23 turns off, thereby stopping the receiving induction coil 24.

[0053] When both the transmitting induction coil 14 and the receiving induction coil 24 start to work, the receiving power supply starts to charge.

[0054] With this structural design, when receiving module 2 is placed on transmitting module 1, the magnetic attraction between receiving magnetic member 21 and transmitting metal ring 12, as well as the magnetic attraction between transmitting magnetic member 11 and receiving metal ring 22, can fine-tune the placement of receiving module 2. This can generate a driving force to shift receiving module 2, even if it's not positioned precisely, toward its correct position. Furthermore, the magnetic attraction maintains the position of receiving module 2 on transmitting module 1, ensuring that it doesn't shift during charging, impacting charging efficiency.

[0055] And only when the receiving magnetic part 21 is aligned and magnetically attracted to the transmitting metal ring 12, and the transmitting magnetic part 11 is aligned and magnetically attracted to the receiving metal ring 22, that is, when the receiving module 2 is accurately aligned with the transmitting module 1, the transmitting induction coil 14 and the receiving induction coil 24 both start working, and the receiving power supply starts charging. When the receiving magnetic part 21 and the transmitting metal ring 12 are misaligned, or the transmitting magnetic part 11 and the receiving metal ring 22 are misaligned, that is, when the receiving module 2 is not accurately placed on the transmitting module 1, the receiving power supply cannot be charged. Therefore, this solution does not require the use of a control device with position detection to ensure that the receiving module 2 and the transmitting module 1 only start charging when they are accurately aligned, can achieve position determination at a low cost, and is convenient for user operation.

[0056] In addition, the transmitting electromagnetic switch 13 is arranged on the inner side of the transmitting metal ring 12, and the receiving electromagnetic switch 23 is arranged on the inner side of the receiving metal ring 22, which makes the structural arrangement more compact and is conducive to product miniaturization.

[0057] The transmitting metal ring 12 and the receiving metal ring 22 are both in a circular ring shape, and the transmitting metal ring 12 and the receiving metal ring 22 can be iron rings.

[0058] The transmitting magnetic element 11 and the transmitting metal ring 12 are symmetrically arranged on either side of the transmitting induction coil 14, and the receiving magnetic element 21 and the receiving metal ring 22 are symmetrically arranged on either side of the receiving induction coil 24. When the transmitting magnetic element 11 is magnetically attracted to the receiving metal ring 22, and the transmitting metal ring 12 is magnetically attracted to the receiving magnetic element 21, the transmitting induction coil 14 and the receiving induction coil 24 are accurately aligned, ensuring charging efficiency.

[0059] The transmitting magnetic member 11 and the transmitting metal ring 12 are respectively provided at both ends of the transmitting module 1, and the receiving magnetic member 21 and the receiving metal ring 22 are respectively provided at both ends of the receiving module 2. This is more conducive to the receiving module 2 and the transmitting module 1 to maintain a more stable position under the magnetic attraction between the receiving magnetic member 21 and the transmitting metal ring 12, and the magnetic attraction between the transmitting magnetic member 11 and the receiving metal ring 22.

[0060] The transmitting module 1 further includes a transmitting power supply, which provides power to the transmitting induction coil 14 when the transmitting induction coil 14 starts working. In other embodiments, the transmitting module 1 may also be connected to an external power line to provide power to the transmitting induction coil 14.

[0061] The surface of transmitting module 1 facing receiving module 2 is called the first surface. The surface of receiving module 2 facing transmitting module 1 is called the second surface. Transmitting electromagnetic switch 13 and receiving magnetic element 21 are configured so that when the distance between the first and second surfaces is less than a set value, transmitting electromagnetic switch 13 senses the magnetic field of receiving magnetic element 21 and turns on.

[0062] The receiving electromagnetic switch 23 and the emitting magnetic member 11 are configured such that when the distance between the first surface and the second surface is smaller than a set value, the receiving electromagnetic switch 23 can sense the magnetic field of the emitting magnetic member 11 and be turned on.

[0063] That is to say, when the receiving module 2 is placed on the transmitting module 1, the transmitting electromagnetic switch 13 can be turned on under the action of a sufficient magnetic field of the receiving magnetic part 21, and the receiving electromagnetic switch 23 can be turned on under the action of a sufficient magnetic field of the transmitting magnetic part 11 only when the distance between the receiving module 2 and the transmitting module 1 is less than the set value.

[0064] This setting is intended to prevent the receiver module 2 from being placed on the transmitter module 1 if a foreign object is present between them. This will cause the receiver module 2 to become displaced and propped up, creating a gap between them. Excessive spacing increases the magnetic induction loss between the transmitting induction coil 14 and the receiving induction coil 24, leading to reduced charging efficiency. To prevent both the transmitting induction coil 14 and the receiving induction coil 24 from operating when there is a gap and charging efficiency is low, the transmitter electromagnetic switch 13 and the receiving electromagnetic switch 23 are configured to only be turned on by a sufficient magnetic field from the receiving magnetic element 21 when the spacing is less than a set value. This setting allows the wireless charging device to implement foreign object detection at a low cost without requiring a control device capable of foreign object detection. In particular, if the foreign object is metallic, damage to the wireless charging device could occur if the transmitting induction coil 14 and the receiving induction coil 24 are in operation at this time.

[0065] In this embodiment, the set value is 1 mm. That is, when a foreign object causes the distance between the receiving module 2 and the transmitting module 1 to be greater than 1 mm, the receiving power supply does not charge. It is understood that the set value can also be set to 1.2 mm, 1.5 mm, etc. as needed.

[0066] The first surface and the second surface are both flat, which makes it easier for the receiving module 2 to be stably placed on the transmitting module 1. In other embodiments, the first surface and the second surface can also be curved or irregular, as long as the first surface and the second surface can match and fit each other.

[0067] The transmitting electromagnetic switch 13 includes a transmitting switch element and a transmitting enable element. When the receiving magnetic member 21 is aligned and magnetically attracted to the transmitting metal ring 12, the transmitting switch element senses the magnetic field of the receiving magnetic member 21 and controls the transmitting enable element to turn on, thereby starting the transmitting induction coil 14. When the receiving magnetic member 21 and the transmitting metal ring 12 are misaligned, the transmitting switch element does not sense the magnetic field of the receiving magnetic member 21 and controls the transmitting enable element to turn off, thereby stopping the transmitting induction coil 14. The receiving electromagnetic switch 23 includes a receiving switch element and a receiving enable element. When the transmitting magnetic member 11 is aligned and magnetically attracted to the receiving metal ring 22, the receiving switch element senses the magnetic field of the transmitting magnetic member 11 and controls the receiving enable element to turn on, thereby starting the receiving induction coil 24. When the transmitting magnetic member 11 and the receiving metal ring 22 are misaligned, the receiving switch element does not sense the magnetic field of the transmitting magnetic member 11 and controls the receiving enable element to turn off, thereby stopping the receiving induction coil 24. The transmitting switch element and the receiving switch element may be a Hall sensor or a magnetoresistive switch, etc., and the transmitting enable element and the receiving enable element may be a field effect transistor or a triode, etc.

[0068] The present invention also provides a smart toilet, comprising a toilet body, a remote control, and a wireless charging device according to any of the above-described embodiments. The transmitter module 1 is provided in the toilet body, and the receiver module 2 is provided in the remote control. A remote control utilizing wireless charging is more convenient for users and facilitates accurate alignment of the remote control with the toilet body for charging. Furthermore, without requiring a position detection control device, charging is ensured only when the remote control and toilet body are accurately aligned, thereby reducing manufacturing costs.

[0069] The toilet seat includes an armrest with a charging position indicator. Transmitter module 1 is located within the armrest. When the remote control is placed within the charging position indicator, the receiving magnetic element 21 aligns and attracts to the transmitting metal ring 12, while the transmitting magnetic element 11 aligns and attracts to the receiving metal ring 22. The armrest provides a handhold when using the smart toilet, enhancing the user experience. The charging position indicator on the armrest makes it easier for users to accurately place the remote control in the correct charging position.

[0070] The following combination Figure 3 and Figure 4 The circuit principles of the wireless charging device are described in detail. The transmitting magnetic component 11 is a magnet M1, the transmitting metal ring 12 is an iron ring T1, and the transmitting electromagnetic switch 13 is a Hall switch module U3. The transmitting enable element in Hall switch module U3 is a field-effect transistor Q1, and the transmitting switch element in Hall switch module U3 is a Hall switch S1. The transmitting induction coil 14 is denoted as transmitting induction coil 14U1, and the transmitting power supply is the armrest power supply V1. The transmitting module 1 also includes a wireless transmitting circuit U2.

[0071] The receiving magnetic element 21 is a magnet M2, the receiving metal ring 22 is an iron ring T2, and the receiving electromagnetic switch 23 is a Hall switch module U5. The receiving enable element in Hall switch module U5 is a field effect transistor Q2, and the receiving switch element in Hall switch module U5 is a Hall switch S2. The receiving induction coil 24 is denoted as receiving induction coil 24U2, and the receiving power source is a battery V2. The receiving module 2 also includes a wireless receiving circuit U4 and a battery charging control circuit U6.

[0072] The armrest power supply V1 outputs power to the Hall switch module U3, which then supplies it to the wireless transmitter circuit U2. If the remote control is not placed in the designated position, the magnet M2 does not magnetically sense the Hall switch S1. This causes the Hall switch S1 to output a high level, turning off the field-effect transistor Q1. This disables the wireless transmitter circuit U2 and the transmitter induction coil 14U1. If the remote control is placed in the designated position, the magnet M2 magnetically senses the Hall switch S1, causing it to output a low level, turning on the field-effect transistor Q1 and supplying power VL1 to the wireless transmitter circuit U2 and the transmitter induction coil 14U1. This causes U1 to generate an oscillating electromagnetic field.

[0073] The receiving induction coil 24U2 and wireless receiving circuit U4 provide output VL2 to the Hall switch module U5. The Hall switch module U5 then outputs to the battery charging control circuit U6, which charges the battery V2. Meanwhile, the battery V2 provides power to the remaining remote control circuits U7. When the remote control is not placed in the designated position, the magnet M1 does not magnetically induce the Hall switch S2. The Hall switch S2 outputs a high level, the field-effect transistor Q2 turns off, and the battery charging control circuit U6 does not operate. When the remote control is placed in the designated position, the receiving induction coil 24U2 receives the oscillating electromagnetic field output by the transmitting induction coil 14U1 through electromagnetic induction. Through the wireless receiving circuit U4, it outputs VL2 to the field-effect transistor Q2 and the Hall switch S2. Simultaneously, the magnet M1 magnetically induces the Hall switch S2, causing it to output a low level, turning on the field-effect transistor Q2. The output VOUT is then provided to the battery charging control circuit U6, which charges the battery V2.

[0074] While the present invention has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary rather than restrictive. Since the present invention can be embodied in a variety of forms without departing from the spirit or essence of the invention, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope of the appended claims. Therefore, all changes and modifications that fall within the scope of the claims or their equivalents are intended to be covered by the appended claims.
