DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figures 1 to 9 In an embodiment of the present invention, a portable modular assembly small household appliance comprises a power supply unit 10 and one or more detachable assembly modules 20; the power supply unit 10 is provided with an energy storage battery 11, a power management circuit 12, and one or more interface devices for connecting the assembly modules 20, and the power management circuit 12 is electrically connected to the energy storage battery 11 and the interface device respectively; each assembly module 20 comprises at least one independent functional unit 21 and its control circuit 22, and is equipped with a switching device, and the switching device matches the interface device of the power supply unit 10 to form a detachable fixed connection, and the control circuit 22 is electrically connected to the power management circuit 12.

[0027] Specifically, the power supply unit 10 can be a power supply device such as a mobile power supply or a power bank, and the assembly module 20 can be a small power-consuming device such as a small fan, a flashlight (ambient night light), a shaver, a beauty instrument, a mobile negative ion oxygen bar, a small hair dryer, a powerful dust blower, etc. Through the mutual cooperation and connection of the adapter device and the interface device, the assembly module 20 can be detachably connected to the power supply unit 10 and form an electrical connection, so that the power supply unit 10 can supply power to the assembly module 20, so that the functional unit 21 of the assembly module 20 can operate and provide corresponding extended functions.

[0028] Secondly, in order to facilitate use and carrying, the power supply unit 10 and the assembly module 20 can be designed as independent modules that can be detachably connected to each other, so as to be convenient for use in different occasions. For example, the user can choose to carry only the power supply unit 10 for single use, or carry the power supply unit 10 and the assembly module 20 at the same time, so that the functions of both can be used at the same time. In particular, when only external electrical equipment needs to be charged, only the power supply unit 10 can be used, and the assembly module 20 can be removed and stored separately. For example, when a mobile phone needs to be charged in a handheld manner, the assembly module 20 does not need to be connected, and only the power supply unit 10 can be electrically connected to the mobile phone. The assembly module 20 can also be placed in a carry-on bag to reduce the volume and weight of the object held by the user when charging.

[0029] Once again, when the corresponding functions of the assembly module 20 are needed, the assembly module 20 is taken out and installed on the positioning plug 61 of the power supply unit 10, and the first conductive part 31 is electrically connected to the second conductive part 41, so as to provide operating power for the functional unit 21 of the assembly module 20, so that it can operate and provide corresponding extended functions. It can be understood that when different functions of the assembly module 20 are needed, the assembly module 20 can be disassembled and replaced, so that one power supply unit 10 can supply power to multiple assembly modules 20 to support their operation.

[0030] In addition, if Figure 7 As shown in the circuit diagram of the power supply unit 10 of the present invention, the functions of the relevant electronic components are described as follows: USB1TYPE-C input and output bidirectional charging interface; USB2USB / A output charging interface; U1 charge and discharge management; U2 battery protection; PG1 is connected to the first conductive part 31 to supply power to the assembly module 20; LED1-LED4 charging and power display; SW1 wake-up button switch; RNTC1 battery temperature protection.

[0031] like Figure 8 As shown in the circuit diagram of the assembly module 20 of the present invention, the functions of the relevant electronic components are described as follows: PG1 is connected to the second conductive part 41 and receives power from the power supply unit 10; U1 driver IC of functional unit 21; JP1 is connected to functional unit 21; SW1 function switch 26 controls the control circuit 22; U2 controls the program control MCU of the control circuit 22.

[0032] like Figure 2 and Figure 5 As shown, preferably, the interface device is provided with a first conductive part 31, and is electrically connected to the power management circuit 12; the adapter device is provided with a second conductive part 41, and is electrically connected to the control circuit 22; the adapter device and the interface device are connected to each other in cooperation so that the first conductive part 31 is electrically connected to the second conductive part 41.

[0033] Specifically, the first conductive part 31 and the second conductive part 41 can cooperate with each other to form a conductive assembly 30, thereby forming an electric energy transmission channel between the functional unit 21 and the energy storage battery 11, so that the functional unit 21 can receive electric energy for operation, thereby providing corresponding extended functions. The first conductive part 31 and the second conductive part 41 can be set by using a variety of conductive products in existing conductive technologies, such as conductive devices corresponding to plugs and sockets, or electromagnetic induction conductive devices, or contact conductive devices that abut each other.

[0034] like Figure 2 and Figure 5 As shown, preferably, the first conductive part 31 is provided with a conductive boss 32 and a conductive contact 33, the conductive boss 32 is fixedly connected to the interface device, the conductive contact 33 is fixedly connected to the conductive boss 32, and forms an electrical connection with the power management circuit 12; the second conductive part 41 is provided with a conductive groove 42 and a conductive spring needle 43, the conductive groove 42 is fixedly connected to the adapter device, the conductive spring needle 43 is installed in the conductive groove 42, and forms an electrical connection with the control circuit 22.

[0035] Specifically, when the adapter is inserted into the interface device, the conductive spring pin 43 of the second conductive part 41 and the conductive contact 33 of the first conductive part 31 can be brought close to each other and finally form an abutment state, thereby achieving an electrical connection state and realizing the effect of transmitting electric energy. The conductive spring pin 43 can be set as a pogo pin connector in existing products. Pogo pin is a precision connector widely used in electronic products such as mobile phones and power supplies. The Chinese name of pogo pin is spring pin, which is mainly used for current and signal transmission, that is, charging and conducting.

[0036] Secondly, in order to facilitate the installation of the conductive groove 42, a corresponding connecting bottom cover 25 can also be provided at the adapter of the assembly module 20. The surrounding positions of the connecting bottom cover 25 are fixedly connected to the adapter of the assembly module 20, and the conductive groove 42 can be fixedly connected to the middle part of the connecting bottom cover 25. At the same time, the conductive groove 42 is also recessed to a certain depth into the interior of the assembly module 20, thereby forming a groove corresponding to the conductive boss 32, so that the conductive boss 32 can be inserted into the conductive groove 42 to form an accurate docking posture, so that the first conductive part 31 and the second conductive part 41 form a stable electrical connection.

[0037] like Figure 3 and Figure 4 As shown, preferably, the conductive contact 33 is provided with a first contact 34 and a plurality of second contacts 35, the first contact 34 is provided at the central axis of the conductive boss 32, and the plurality of second contacts 35 are evenly distributed along the circumference of the central axis of the conductive boss 32, and the distances from the central axis are the same; the conductive spring needle 43 is provided with a first spring needle 44 and a plurality of second spring needles 45, the first spring needle 44 is provided at the central axis of the conductive groove 42, and the plurality of second spring needles 45 are evenly distributed along the circumference of the central axis of the conductive groove 42, and the distances from the central axis are the same.

[0038] Specifically, when the assembly module 20 is installed on the power supply unit 10, the first contact 34 and the first spring needle 44 can be made to correspond to each other, so as to abut against each other to form an electrical connection. Similarly, the second contact 35 and the second spring needle 45 can be made to correspond to each other, so as to abut against each other to form an electrical connection. When the assembly module 20 is installed on the power supply unit 10, in order to avoid the user needing to distinguish the installation direction, a plurality of second contacts 35 can be arranged to be evenly distributed around the circumference of the central axis of the conductive boss 32. For example, in a conductive boss 32 having a roughly quadrilateral cross-section, four second contacts 35 can be arranged, respectively arranged at the positions of the cross-sectional corners of the conductive boss 32. Similarly, the conductive spring needle 43 can also be provided with a plurality of second contacts 35, which are evenly distributed around the circumference of the central axis of the conductive groove 42. For example, four second spring needles 45 can be provided in a conductive groove 42 having a roughly quadrilateral cross-section, and are respectively provided at the positions of the cross-sectional corners of the conductive groove 42, so that they can correspond to the second contacts 35 of the conductive boss 32, so that when the assembly module 20 is docked and installed on the power supply unit 10, the conductive boss 32 is embedded in the conductive groove 42, so that the second contacts 35 just abut against the second spring needles 45, thereby forming an electrical connection.

[0039] Secondly, since the conductive protrusion 32 is already provided with four second contacts 35, the conductive groove 42 can only be provided with two second spring pins 45, so that the two second spring pins 45 are respectively provided at two positions of the cross-sectional angle of the conductive groove 42 on the diagonal line, so that the assembly module 20 can be inserted into the interface device of the power supply unit 10 in any direction along the central axis of the assembly module 20, so that the two second spring pins 45 can be electrically connected with the second contacts 35 of the conductive protrusion 32. Even in a more cost-saving solution, the conductive groove 42 can only be provided with one second spring pin 45, and since the second contacts 35 are provided at the positions corresponding to the second spring pins 45, the electrical connection between the second conductive part 41 and the first conductive part 31 can also be achieved.

[0040] Again, since direct current distinguishes between positive and negative poles, the first contact 34 and the first spring pin 44 can be set as positive poles, and the plurality of second contacts 35 and the plurality of second spring pins 45 can be set as negative poles. Alternatively, the first contact 34 and the first spring pin 44 can be set as negative poles, and the plurality of second contacts 35 and the plurality of second spring pins 45 can be set as positive poles.

[0041] In addition, if Fig. 9As shown, a function switch 26 can also be installed on the assembly module 20, so that the function switch 26 is electrically connected to the control circuit 22, so that the control circuit 22 can be controlled accordingly, and various functions of the function unit 21 of the assembly module 20 can be adjusted. For example, the function unit 21 can be controlled to be turned on or off, or its power can be controlled, or its speed can be controlled.

[0042] like Figure 3 , Figure 4 and Figure 5 As shown, preferably, the conductive boss 32 is coaxially arranged with the interface device, and the cross-sectional angle of the conductive boss 32 corresponds to the cross-sectional edge of the interface device; the conductive groove 42 is coaxially arranged with the adapter device, and the cross-sectional angle of the conductive groove 42 corresponds to the cross-sectional edge of the adapter device.

[0043] Specifically, in order to more conveniently arrange the conductive boss 32 on the end face of the relatively small interface device, the first contact 34 and the second contact 35 are spaced relatively wide from each other. It is preferred that the cross-sectional angle of the conductive boss 32 and the cross-sectional edge of the interface device are arranged to correspond to each other. Furthermore, the corner point of the cross section of the conductive boss 32 can be precisely matched with the midpoint of the cross-sectional edge of the interface device, thereby ensuring that the axis of the conductive boss 32 coincides with the perpendicular bisector of the cross-sectional edge of the interface device. Similarly, the conductive groove 42 and the adapter device can also be arranged in this way.

[0044] like Figure 2 , Figure 3 and Figure 5 As shown, preferably, the interface device is provided with a first magnetic attraction portion 51, and the adapter device is provided with a second magnetic attraction portion 52, and the first magnetic attraction portion 51 and the second magnetic attraction portion 52 correspond to each other to form a magnetic adsorption connection.

[0045] Specifically, when the power supply unit 10 and the assembly module 20 are close to each other and gradually combined to form a connection state, the first magnetic attraction portion 51 and the second magnetic attraction portion 52 can be attracted to each other through magnetic attraction to form a relatively stable magnetic connection. When the two need to be separated, the power supply unit 10 and the assembly module 20 can be held separately, and a certain pulling force can be applied to both ends to overcome the adsorption force of the magnetic connection and disassemble and separate the two.

[0046] Secondly, since both ends of the two devices that need to be connected can be equipped with strong magnets, the magnetic adsorption and separation functions between the components are realized. This connection structure can achieve rapid connection and stable fixation of components through magnetic force, and can be easily separated when sufficient external force is applied, which is suitable for application scenarios that require rapid assembly and disassembly.

[0047] like Figures 1 to 6As shown, preferably, the interface device is provided with a positioning plug 61, the adapter device is provided with a positioning sleeve 62, and the positioning plug 61 can be inserted into the positioning sleeve 62, so that the power supply unit 10 and the assembly module 20 form a detachable fixed connection.

[0048] Specifically, the outer diameter of the positioning plug 61 is substantially the same as the diameter of the inner wall of the positioning sleeve 62, so that when the positioning sleeve 62 is sleeved on the positioning plug 61, the outer wall of the plug and the inner wall of the sleeve fit closely, thereby enhancing the integrity of the structure and the stability of the overall connection. It also makes the connection between the power supply unit 10 and the assembly module 20 more secure, reduces relative movement, and improves the reliability and stability of the connection between the two.

[0049] Secondly, in order to enable the positioning assembly 60 to assist in the locking operation, preferably, the magnetic block of the first magnetic part 51 can be installed at the end of the positioning plug 61, and the magnetic block of the second magnetic part 52 can be installed on the connection bottom cover 25 at the bottom of the positioning sleeve 62, so that after the positioning plug 61 is inserted into the positioning sleeve 62, the magnetic blocks of the first magnetic part 51 and the second magnetic part 52 can just be attracted to each other to form a relatively stable magnetic connection. It can be understood that the first magnetic part 51 and the second magnetic part 52 can be set as magnets in existing products.

[0050] Next, a thinner layer of PET film 14 can be provided on the end face of the positioning plug 61. The PET film 14 will not affect the magnetic attraction force, thereby covering the first magnetic attraction part 51. It can prevent the collision damage caused by the direct contact between the two magnetic attraction parts, and at the same time, it can also cover the installation bolts of the power supply unit 10, thereby improving its aesthetics and making the power supply unit 10 have corresponding aesthetics when used independently.

[0051] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, preferably, the positioning plug 61 is configured as a polyhedral column, the positioning sleeve 62 is configured as a polyhedral sleeve, the first magnetic portion 51 is provided with a plurality of magnetic blocks, which are respectively arranged at the corresponding corners of the polyhedral column; the second magnetic portion 52 is provided with a plurality of magnetic blocks, which are respectively arranged at the corresponding corners of the bottom surface of the polyhedral sleeve.

[0052] Specifically, for example, the positioning plug 61 can be set as a tetrahedral column, and the first magnetic attraction portion 51 is provided with four magnetic blocks, which are respectively arranged at the four corners of the tetrahedral column. Similarly, the positioning sleeve 62 can be set as a tetrahedral sleeve, and the second magnetic attraction portion 52 is provided with four magnetic blocks, which are respectively arranged at the four corners of the bottom surface of the tetrahedral sleeve.

[0053] Secondly, in order to further improve the connection firmness after the power supply unit 10 and the assembly module 20 are combined, it is preferred to set a plurality of magnetic blocks, such as setting four groups of magnetic blocks that form an adsorption effect on each other, and respectively install them at the four corners of the interface device and the four corners of the adapter device, so that the corresponding four corners can be adsorbed to each other to form a strong magnetic connection. After such a setting, no matter when the assembly module 20 is connected and installed on the power supply unit 10 in any installation direction, the first conductive part 31 and the second conductive part 41 can be abutted against each other and form an electrical connection. Moreover, the special shape (tetrahedral column and tetrahedral sleeve) between the positioning sleeve 62 and the positioning plug 61 can be used to cooperate, so that the two are easy to disassemble and connect. At the same time, the mutual cooperation of the conductive protrusion 32 and the conductive groove 42 can also be used to assist the connection between the first conductive part 31 and the second conductive part 41, so that the conductive contact 33 and the conductive spring pin 43 can be accurately aligned to achieve an electrical connection state of abutting each other.

[0054] Again, in order to improve the aesthetics and comfort of use, the outer wall of the positioning plug 61 and the power unit 10 can also be set as a rounded tetrahedron column, and the positioning sleeve 62 can also be set as a rounded tetrahedron sleeve. At the same time, the handle end 23 of the assembly module 20 can also be set as a rounded tetrahedron column, so that the appearance design style of the power unit 10 and the assembly module 20 are unified, and a sense of integrity is formed after the docking is completed, which enhances the aesthetics. The functional end 24 of the assembly module 20 can be changed according to the corresponding function. For example, when the assembly module 20 is a small fan, its corresponding functional end 24 can be set to a cylindrical shape. When the assembly module 20 is a razor, its corresponding functional end 24 can be a cylindrical shape of a rotary razor, or a flat shape of a reciprocating razor.

[0055] In addition, if Fig. 9 As shown, the power supply unit 10 can also be provided with a charge and discharge interface 13, such as providing a USB interface of various specifications in the prior art, so that it can not only charge the energy storage battery 11 inside the power supply unit 10, but also discharge the energy storage battery 11 externally through the USB interface, thereby realizing the charge and discharge function of the power supply unit 10. Moreover, the assembly module 20 and the power supply unit 10 are connected in a combined manner using a detachable connection structure, which can be convenient for using the corresponding functions of the assembly module 20 at any time, and can also be used when the assembly module 20 is not needed, without carrying the assembly module 20 extra. For example, when only an external mobile phone needs to be charged, it is not necessary to drag the assembly module 20 together, which improves people's use experience. At the same time, the assembly module 20 can also be replaced to switch different functions.

[0056] In one embodiment, if Figure 2 , Figure 4 and Figure 5As shown, preferably, the outer diameter of the positioning plug 61 can be smaller than the outer diameter of the overall outer shell of the power supply unit 10, thereby forming a step position between the positioning plug 61 and the overall shell of the power supply unit 10, so that when the positioning plug 61 is inserted into the positioning sleeve 62, the positioning sleeve 62 can be just sleeved at the position of the step position, and the outer diameter of the positioning sleeve 62 is slightly equal to the outer diameter of the shell of the power supply unit 10, so that after the assembly module 20 and the power supply unit 10 are connected to each other, a more beautiful overall shape can be formed.

[0057] In another embodiment, if Figure 6 As shown, preferably, in order to enable the power supply unit 10 to maintain an overall shape when used independently and reduce the thickness of the outer shell of the power supply unit 10, no step position may be set, that is, the outer periphery of the shell of the power supply unit 10 is set to be a straight cylinder, and then the inner wall diameter of the positioning sleeve 62 of the assembly module 20 is set to be equal to or slightly larger than the outer wall diameter of the shell of the power supply unit 10, so that the positioning sleeve 62 can be directly sleeved on the outer shell of the positioning plug 61 of the power supply unit 10 to form a connection state of docking with each other.

[0058] Embodiment 1: Small fan module The power supply unit 10 is a standard mobile power supply, with a built-in 10000mAh battery, a power management IC (integrated circuit), and a trihedral cylindrical positioning plug 61. The interface device on the positioning plug 61 has four conductive contacts 33, a central contact is located at the central axis, and three peripheral contacts correspond to the midpoint positions of the cross-sectional edges of the trihedral cylindrical shape. The central contact provides positive voltage, and the peripheral contacts provide negative voltage and grounding.

[0059] Fan module: A small fan with a built-in control circuit 22 and a positioning sleeve 62 in the shape of a trihedron sleeve. The adapter on the positioning sleeve 62 has two spring contact pins for connecting the contacts of the power supply unit 10. One spring contact pin located at the central axis is connected to the positive voltage and corresponds to the central contact of the power supply unit 10. The other spring contact pin connected to the negative voltage and the ground terminal is set at the midpoint position corresponding to the cross-sectional edge of the trihedron sleeve and corresponds to the peripheral contacts of the power supply unit 10.

[0060] The interface device of the power supply unit 10 and the adapter device of the assembly module 20 are both provided with corresponding magnet blocks to realize magnetic connection, which is used to enhance alignment and secure connection.
