Abstract
Description
Technical Field
[0001] This utility model relates to a toilet, specifically a battery-swapping smart toilet. Background Technology
[0002] Current smart toilets are powered by an external power plug that connects directly to a fixed socket. However, some locations where smart toilets are installed may not have pre-installed sockets, such as older buildings or bungalows. In these cases, there are no sockets around the toilet installation area, and it's inconvenient to add a secondary power source. In these situations, the smart toilet is used without a fixed power supply. While it can be powered by external dry-cell batteries for basic flushing, other functions like seat heating, feminine wash, and warm air drying require significantly more power. Dry-cell batteries alone cannot meet the demands of these functions, thus greatly limiting the practicality and convenience of smart toilets. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a battery-swappable smart toilet that can meet the needs of users to use the smart toilet normally by setting a replaceable battery in the cavity of the toilet body in the absence of a fixed power source.
[0004] The technical problem of this utility model is solved by the following technical solution:
[0005] A battery-swappable smart toilet includes a toilet body and a cavity formed within the toilet body. The side of the toilet body has a side window communicating with the cavity. It also includes a replaceable battery, which is installed into the cavity through the side window and sealed by a cover that is detachably attached to the side window. The battery forms a pluggable circuit connection with a power supply plug on the outside of the toilet body.
[0006] The toilet has two side windows, which are respectively located on both sides of the toilet body. Each side window is independently fitted with a battery and then detachably closed by the cover.
[0007] The toilet body is also provided with a rear window that connects to the cavity. The power plug outside the toilet body enters the cavity through the rear window and forms a pluggable circuit connection with the battery.
[0008] The inner side of the cover is provided with a mounting ring, which is engaged inside the side window and causes the cover to close onto the side window.
[0009] The mounting ring has multiple locking protrusions on its outer circumferential surface, and the mounting ring is detachably fixed to the side window via these multiple locking protrusions.
[0010] Each of the aforementioned protrusions is an arc-shaped block, and multiple protrusions are symmetrically arranged on both sides of the mounting ring.
[0011] The cover is larger than the side window and completely covers the side window.
[0012] The top surface of the battery is equipped with a socket, a switch, and a power indicator light. The power plug on the outside of the toilet body forms a pluggable circuit connection with the socket. The switch is used to control the battery's on / off state. The power indicator light displays the battery's working status.
[0013] The battery is equipped with a handle and a charging port on its side.
[0014] The bottom surface of the battery is provided with several support feet.
[0015] Compared to existing technologies, this invention primarily features a side window connecting the toilet bowl to the cavity on its side. A replaceable battery is inserted into the cavity through this window and then sealed by a detachable cover, maintaining the toilet bowl's aesthetic appearance. This built-in battery utilizes the unused space within the cavity and allows for a pluggable connection between the battery and the external power supply. Compared to traditional dry cell batteries, the battery provides significantly more power, ensuring the normal operation of all functions of the smart toilet. Once the battery is depleted, simply open the side window to replace it. Therefore, this improved battery-swappable smart toilet meets user requirements even in locations without pre-installed power outlets, such as older buildings or bungalows where additional power is unavailable, thus eliminating user concerns.

[0022] Battery-swappable smart toilets, such as Figure 1 As shown, it is a tankless toilet with functions such as automatic flushing, women's cleaning, and warm air drying. It has a simple appearance with smooth rounded transitions and a size that meets the needs of most users. In particular, it can be powered by a replaceable rechargeable battery 3 to meet the normal operation of all functions of the smart toilet, thus facilitating the use of customers even in scenarios without a fixed power source. Its structure mainly includes the toilet body 1 and the cavity 11 formed inside the toilet body.
[0023] The toilet body 1 has a side window 12 communicating with the cavity 11 on its side, and also includes a replaceable battery 3. The battery is inserted into the cavity 11 through the side window 12 and sealed by a cover 2 that is detachably fitted onto the side window 12. In this embodiment, for example... Figure 1 The design shows two side windows 12, which are respectively set on the two sides of the toilet body 1. Each side window 12 is a rectangular window, and after the battery 3 is installed independently, they are detachably closed by the configured cover 2.
[0024] In this way, the inner cavity 11 of the smart toilet can be equipped with two batteries 3 at the same time, so as to provide more power and meet more usage scenarios.
[0025] The cover 2 is made of ABS, PP, PE or urea-formaldehyde material, and the surface can be ceramic or natural white, similar in color to the ceramic body.
[0026] The outer side of the cover 2 serves as a decorative surface, and a rectangular mounting ring 21 is provided on the inner side of the cover 2. The cover 2 is secured to the side window 12 by the mounting ring, so that the cover 2 can cover the side window 12. The size of the cover 2 needs to be larger than the side window 12 to completely cover the side window and ensure the aesthetic appearance of the toilet body.
[0027] The mounting ring 21 has a locking structure within the side window 12, which consists of multiple locking protrusions 22 on the outer circumferential surface of the mounting ring 21. For example, in this embodiment... Figure 3As shown, multiple locking protrusions 22 are symmetrically arranged on both sides of the mounting ring 21, with 4 protrusions on each side. In practice, 3 to 6 protrusions can be selected to meet the needs of use and ensure uniform force during locking. Each locking protrusion 22 is an arc-shaped block, specifically a semi-circular protrusion with a radius of 1mm to 3mm. Therefore, the mounting ring 21 can be detachably fixed inside the side window 12 by multiple locking protrusions 22.
[0028] Then, the rear part of the toilet body 1 is also provided with a rear window 13 that connects to the cavity 11, and the power plug (not shown in the figure), that is, the power cord plug, outside the toilet body can enter the cavity 11 through the rear window 13 and form a pluggable circuit connection with the battery 3.
[0029] The battery 3 is a rechargeable battery with a regular, square shape that matches the shape of the side window 12 for easy access. A single battery can store 5 to 15 kWh of electricity, with a single use time of 5 to 15 days. It consumes an average of 1 kWh per day and outputs 220V, thus meeting the requirements of a smart toilet. It also uses lithium iron phosphate cells, has a stainless steel casing, and has an internal short-circuit protector to ensure safety during use.
[0030] The top surface of the battery 3 is equipped with a socket 31, a switch 32, and a power indicator light 33. In this embodiment, the socket 31 is a three-hole socket and serves as the main power output terminal. The power plug on the outside of the toilet body can form a pluggable circuit connection with the socket. The switch 32 is the main discharge switch for the battery, mainly used to control the on / off state of the battery. When the switch is closed, the battery will no longer output power. The power indicator light 33 indicates the battery's power usage at different stages, that is, it can display the battery's working status. For example, it can display three colors: green, red, and yellow. Green indicates that the power is normal, red indicates that the power is below 20%, and yellow indicates that it is charging. When the charging level reaches 80%, the power indicator light will turn green.
[0031] Meanwhile, the battery is equipped with a handle 34 and a charging port 35 on its side. The handle 34 makes it easy to take the battery out of the cavity through the side window. The handle can be made of ABS or nylon, which is safer, more durable and corrosion-resistant. The charging port 35 is the only input port for charging the battery. It can charge the battery and uses a special plug design to avoid user error.
[0032] The battery has several support feet 36 on its bottom surface to lift the entire battery, thereby improving the overall heat dissipation and making it safer to use.
[0033] This invention cleverly integrates the battery 3 into the cavity 11 for concealment, thus utilizing the unused space within the cavity 11. It also allows for a pluggable circuit connection between the battery and the external power plug of the toilet body, facilitating easy removal for recharging. Compared to traditional dry cell batteries, the battery 3 provides significantly more power, ensuring the normal operation of all functions of the smart toilet. Once the battery is depleted, simply opening the side window 12 allows for easy replacement. This simple battery replacement structure makes actual use more convenient for users.
[0034] Therefore, the improved battery-swapping smart toilet can meet users' needs in places without pre-installed sockets, that is, in scenarios without a fixed power supply. Thus, it does not affect normal use in some older buildings, bungalows, and other early housing structures where sockets are not installed, or where it is inconvenient to add a fixed power supply. This enriches the product diversity, effectively eliminates users' purchasing concerns, and thus meets the needs of more usage scenarios and a wider user group.
