Description

Technical Field

[0001] This utility model relates to the field of sanitary ware technology, and in particular to a backup battery module for a smart toilet. Background Technology

[0002] In the field of smart toilets, the operation of core functions such as drying and sensor flushing all rely on external power supply. To avoid the interruption of external power supply affecting the normal use of smart toilets, toilets are usually equipped with backup batteries to provide emergency power.

[0003] Conventional smart toilet battery modules use a connection between the battery box and a male / female power connector to establish electrical connection between the battery and the toilet's circuitry. For example, the smart toilet battery disclosed in announcement number CN217601601U has a male connector exposed outside the battery box. One end of the positive and negative wires in the cable connects to the positive and negative terminals on the battery box, while the other end connects to a male connector with an insulating sheath. Most of the positive and negative wires and the male connector are located outside the battery box, with the female connector of the cable also outside the box. From the existing structure, placing the male connector outside the battery box requires an insulating sheath for the male connector and insulating sheaths for the wires, resulting in higher material consumption and a more complex structure. Furthermore, this connection method necessitates addressing waterproofing issues at both the male and female connectors, posing potential safety hazards for daily use. Therefore, further improvements are needed to the existing backup batteries for smart toilets. Summary of the Invention

[0004] The purpose of this invention is to provide a backup battery module for a smart toilet to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a backup battery module for a smart toilet, comprising a battery box, wherein the battery box is composed of a first shell and a second shell joined together, the interior of the battery box has a receiving cavity in which a battery pack is installed, a plug-in hole is provided on the upper end face of the battery box, and a fastening bracket is provided on the inner wall of the battery box directly below the plug-in hole, on which a DC power male connector is installed, the battery module further comprising a power cord connecting the smart toilet and the DC power male connector, one end of the power cord being provided with an insulating sheath, the end of the insulating sheath having a DC power female connector, and the outer periphery of the insulating sheath having an outer ring boss, when the DC power female connector is connected to the DC power male connector in the battery box through the plug-in hole, the bottom end face of the outer ring boss abuts against the outer end face of the battery box and completely covers the plug-in hole.

[0006] The first and second housings are each provided with a limiting seat on their inner walls directly below the insertion hole. Both sets of limiting seats have U-shaped notches. When the first and second housings are aligned, the two sets of limiting seats are aligned to form a fastening seat with a locking position on the inner side. The metal core of the DC power connector is placed in the locking position.

[0007] A stop plate is constructed on the inner wall of the first housing below the limiting seat. The stop plate is spaced apart from the limiting seat. The insulating base of the DC power connector is placed between the stop plate and the limiting seat and abuts against the stop plate.

[0008] A protrusion is constructed between the limiting seat and the stop plate, and a corresponding recess is provided on the insulating base of the DC power supply male seat, the recess engaging with the protrusion.

[0009] The insulating sheath of the power cord has a positioning post between the outer ring boss and the DC power female socket. The outer diameter of the positioning post is smaller than the outer diameter of the outer ring boss. The battery box has a positioning slot between the limiting seat and the insertion hole. Based on the docking of the DC power male socket and the DC power female socket, the positioning post is inserted into the positioning slot.

[0010] The first housing and the second housing are each provided with a positioning seat between the limiting seat and the insertion hole. Each of the two sets of positioning seats is provided with a semi-circular notch. When the first housing and the second housing are aligned, the two sets of positioning seats are aligned to form a positioning slot that matches the positioning post, so as to limit the position of the insulating sleeve.

[0011] The positioning post is fitted with a waterproof sealing ring on its outer surface, and a sealing groove is provided around the positioning slot corresponding to the waterproof sealing ring. The waterproof sealing ring and the sealing groove are engaged with each other.

[0012] The centers of the insertion hole, the positioning slot, and the mounting position are all on the same straight line.

[0013] The insulating sheath is connected to a waterproof sleeve, which is detachably fitted onto the DC power supply socket.

[0014] Compared with existing technologies, the advantages of this utility model are as follows: By constructing a fastening bracket directly below the battery box's insertion hole, the DC power male connector and positive and negative wires can be installed inside the battery box, thus eliminating the need for insulating sleeves around the DC power male connector and insulating cable sheaths on the positive and negative wires, significantly simplifying the structure of the battery module's output end and reducing production material consumption. The DC power female connector on the power cord passes through the insertion hole and connects with the DC power male connector inside the battery box. Since the connection point between the DC power male and female connectors is located inside the battery box, only the waterproofing issue at the insertion hole needs to be addressed. Furthermore, by installing a waterproof sealing ring on the positioning post of the insulating sleeve and having the bottom surface of the outer ring protrusion on the insulating sleeve abut against the outer end face of the battery box and completely cover the insertion hole, the waterproofing effect at the insertion hole is enhanced. This effectively reduces the potential risks of using the smart toilet backup battery module in humid environments, reduces the occurrence of power supply failures, and ensures the reliability of emergency power supply from the backup battery.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: As Figure 1-10 The diagram illustrates a backup battery module for a smart toilet, comprising a battery housing 1. The battery housing 1 is composed of a first housing 11 and a second housing 12 joined together. The interior of the battery housing has a receiving cavity in which a battery pack 13 is installed. A circular insertion hole 14 is provided on the upper surface of the battery housing 1. A fastening bracket 15 is provided on the inner wall of the battery housing 1 directly below the insertion hole 14. A DC power connector 16 is mounted on the fastening bracket 15. The fastening bracket 15 is located within the receiving cavity and positioned to one side of the battery pack 13, such that the DC power connector... Completely housed inside the battery box, with its plug-in end facing the plug-in hole, the DC power connector 16 consists of a cylindrical metal core, an insulating base located at the bottom of the metal core, wiring terminals, and positive and negative wires connected to the wiring terminals. The positive and negative wires are respectively connected to the positive and negative terminals of the battery pack in the receiving cavity. Compared with the conventional battery module output end structure, the DC power connector built into the battery box can eliminate the need for its outer insulating sleeve and the insulating cable sleeve on the wires, greatly simplifying the structure of the battery module output end and reducing the production materials of the battery module.

[0019] The battery module also includes a power cord 2 connecting the smart toilet and the DC power male socket. The power cord 2 includes a cable, one end of which is provided with an insulating sheath 21. The end of the insulating sheath has a DC power female socket 22 that matches the DC power male socket. The other end of the cable has a terminal connector for connecting the toilet circuit. The outer periphery of the insulating sheath 21 has an outer ring boss 23. The outer diameter of the outer ring boss 23 is larger than the outer diameter of the insulating sheath 21 and the outer diameter of the insertion hole 14. When the DC power female socket 22 is connected to the DC power male socket 16 in the battery box through the insertion hole, the bottom surface of the outer ring boss 23 abuts against the outer end surface of the battery box 1 and completely covers the insertion hole 14, forming the first waterproof barrier to prevent water vapor from entering the battery box.

[0020] It should be noted that the structure of the DC power connector and power cord as well as the materials used to make the insulating sheath are all existing technologies, and will not be described in detail here.

[0021] Specifically, a hook is constructed on the inner wall of the first housing, and a notch is provided on the outward-facing side of the hook. A protruding block is provided on the inner wall of the second housing at a position corresponding to the notch. The first housing and the second housing are connected to each other by the protruding block being embedded in the notch of the hook. The battery pack is composed of multiple lithium batteries connected in series. Both the inner walls of the first housing and the second housing are provided with arc-shaped retaining plates that match the outer diameter of the batteries, which can be used to fix the battery pack.

[0022] Specifically, the inner walls of the first housing 11 and the second housing 12 are each provided with an integrally formed limiting seat 17 directly below the insertion hole 14. Each set of limiting seats 1 is composed of two horizontal limiting plates distributed longitudinally along the battery box. Each set of limiting seats 17 has a U-shaped notch 18 on the opposite side. When the first housing 11 and the second housing 12 are aligned, the two sets of limiting seats 17 are aligned to form a fastening seat 15 with a locking position 19 on the inner side. The height of the fastening seat 15 is adapted to the height of the metal core of the DC power male connector 16. The cross-section of the locking position 19 is circular, and the two ends of the locking position 19 are connected. Its diameter matches the outer diameter of the metal core of the DC power male connector 16. The metal core of the DC power male connector 16 is placed in the locking position 19 so as to mate with the DC power female connector. To ensure a more secure installation of the DC power connector on the limiting seat, the depth of the U-shaped notch on the limiting seat of the first housing is greater than the depth of the U-shaped notch on the limiting seat of the second housing. The metal core is interference-fitted with the U-shaped notch on the first housing to ensure that the DC power connector is locked by one of its limiting seats, while the other limiting seat plays an auxiliary positioning role.

[0023] To further improve the installation stability of the DC power connector, a stop plate 101 is constructed on the inner wall of the first housing 11 below the limiting seat 17. The stop plate is horizontally arranged and spaced apart from the limiting seat 17. The distance between the stop plate 101 and the limiting seat 17 is close to the thickness of the insulating base on the DC power connector. The front-to-back extension dimension of the stop plate is shorter than that of the limiting seat, so that the end face of the stop plate facing the second housing is lower than the terminal block, thus avoiding interference between the terminal block of the insulating base and the stop plate. The insulating base of the DC power connector 16 is placed between the stop plate 101 and the limiting seat 17 and partially abuts against the stop plate 101, restricting the longitudinal movement of the DC power connector. Meanwhile, a protrusion 102 is constructed between the limiting seat 17 and the stop plate 101, and a corresponding recess is provided on the insulating base of the DC power male connector 16. When the DC power male connector is installed on the limiting seat, the recess and the protrusion 102 engage with each other to achieve circumferential limiting and prevent the DC power male connector from rotating during docking.

[0024] Preferably, the insulating sheath 21 of the power cord has a positioning post 24 between the outer ring boss 23 and the DC power female socket 22. The outer ring boss, the positioning post and the insulating sheath are integrally formed, and its outer diameter is smaller than the outer diameter of the outer ring boss 23. The battery box 1 has a positioning slot 104 between the limiting seat 17 and the insertion hole 14. The inner diameter of the positioning slot 104 and the insertion hole matches the outer diameter of the positioning post 24. Based on the docking of the DC power male socket 16 and the DC power female socket 22, the positioning post 24 is inserted in the positioning slot 104 to limit the radial position of the insulating sheath and prevent docking misalignment.

[0025] Specifically, the first housing 11 and the second housing 12 are each provided with a positioning seat between the limiting seat 17 and the insertion hole 14. The two sets of positioning seats are respectively provided with a semi-circular notch 106 on the opposite side. When the first housing and the second housing are aligned, the two sets of positioning seats are aligned to form a positioning slot 104 that matches the positioning post 24, so as to limit the position of the insulating sleeve.

[0026] To improve the waterproof performance at the positioning slot, a waterproof sealing ring 25 is fitted on the outer surface of the positioning post 24. The waterproof sealing ring is made of rubber. A sealing groove 105 matching the waterproof sealing ring is provided at the corresponding position of the positioning slot. The waterproof sealing ring 25 and the sealing groove 105 engage with each other to form a second waterproof barrier. In addition, the thickness of the positioning slot is 6mm. The connection point between the DC power male and female connectors is inside the battery box, 6mm away from the insertion hole. The connection point is completely placed inside the battery box. Combined with the two waterproof barriers, it effectively prevents external moisture from entering the battery box from the insertion hole.

[0027] In this embodiment, the centers of the insertion hole 14, the positioning slot hole 104, and the mounting position 19 are all on the same straight line, ensuring that the DC power female and the positioning post can smoothly enter the battery box through the insertion hole and dock with the DC power male.

[0028] Since the backup battery module is used during a power outage, and the power cord and battery box are not connected when the smart toilet is normally powered on, waterproof protection is required for the DC power connector exposed to the external environment. Therefore, a waterproof sleeve 26 is connected to the insulating sleeve 21. The waterproof sleeve 26 consists of a connecting rope and a cylindrical sleeve at the end of the connecting rope. The inner cavity of the cylindrical sleeve matches the DC power connector. The connecting rope and the cylindrical sleeve are integrally formed and both are made of rubber. The connecting rope can be adjusted in angle and direction. When the battery module is not connected to the smart toilet, the waterproof sleeve 26 is placed on the DC power connector 22 to protect it from dust and moisture entering the connector interface. When connection is required, the waterproof sleeve is removed.

[0029] In this embodiment, the battery pack is placed in the receiving cavity and fixed by the arc-shaped retaining plates on the first and second housings. The limiting seat and the insertion hole are located on one side of the battery pack. The metal core of the DC power male connector is assembled in the mounting position, and its insulating base is aligned with the gap between the stop plate and the limiting seat, so that the protrusion is inserted into the inner recess. The DC power male connector is installed in the receiving cavity with the insertion end facing the insertion hole. The positive and negative ends of the battery pack are connected to the positive and negative wires on the DC power male connector. When it is necessary to connect to the smart toilet, the waterproof sleeve of the DC power female connector is removed, and the DC power female connector is aligned with the insertion hole of the battery box. The positioning pin is inserted into the positioning slot until the DC power female connector and the DC power male connector are tightly connected. At this time, the outer ring protrusion abuts against the outer end face of the battery box, and the waterproof sealing ring is inserted into the sealing groove.

[0030] This embodiment, through the above structural design, not only simplifies the structure of the battery module output end, reduces the need for insulating sleeves on the DC power connector and insulating cable sleeves on the wires, saving production materials, but also solves the waterproofing problem at the plug-in hole through a double waterproof design, reducing the potential hazards of use in humid environments and ensuring the reliability of emergency power supply from the backup battery.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
