Abstract
Description
Technical Field
[0001] This utility model relates to the field of toilet technology, specifically to a scalding-proof and safe toilet seat heater. Background Technology
[0002] According to patent number CN222367607U, a heated toilet seat with an overheat protection structure is described. By installing a fuse inside the toilet seat, the fuse can prevent the toilet seat from overheating and protect the heating electronic unit of the toilet seat. As can be seen from the design scheme in the above patent, the fuse is located inside the toilet seat. Users will squeeze the fuse for a long time during use. This will not only damage the fuse, but also make it troublesome to disassemble and replace after the fuse is damaged, which is impractical.
[0003] Therefore, there is an urgent need for a scalding-proof and safe toilet seat heater that can protect the normal use of the safety mechanism and is easy to replace. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a scalding-proof and safe toilet seat heater, which solves the problems of scalding prevention and safety of toilet seat heaters. The external safety mechanism can prevent the fuse from being damaged by pressure and is easy to replace.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a scalding-proof and safe toilet seat heater, comprising a toilet seat ring and a heating ring, wherein a heating wire is provided inside the heating ring, characterized in that: an external safety mechanism is provided at the connection point of the heating wire; the external safety mechanism includes an external box fixed to the outside of the toilet seat ring, a fuse tube is provided inside the external box, and the heating wire is connected to the fuse tube by passing through the external box via a concealed wire; a temperature-changing mechanism is provided on the upper surface of the toilet seat ring; the temperature-changing mechanism improves temperature identification.
[0006] Furthermore: the temperature-changing mechanism includes multiple color-changing blocks with equal spacing, the color-changing blocks are fixed on the surface of the toilet seat, and the toilet seat is filled with color-changing particles.
[0007] Furthermore: the outer side of the outer box is hinged to the box cover, and a sealing ring is fixed on the inner side of the box cover, the sealing ring being abutted against the inner edge of the outer box.
[0008] Furthermore, the color temperature changing blocks are evenly distributed circumferentially along the upper surface of the toilet seat.
[0009] Furthermore: the color temperature changing block turns red at a temperature of 40°C or higher, and the color changing particles are slightly red at 35°C-40°C.
[0010] Furthermore, the lid and the outer box are connected by a snap-fit mechanism.
[0011] This invention provides a scalding-proof and safe toilet seat heater. Compared with the prior art, it has the following advantages:
[0012] This anti-scalding safety toilet seat heater features an external fuse mechanism that allows for rapid overload melting without the need for disassembly and replacement, preventing damage to the wiring due to pressure. A dual-stage temperature-changing mechanism provides dual warnings via color blocks and particles: a slight red alert at 35℃ and a full red alert at 40℃, preventing burns. The sealed external box design is waterproof and pressure-resistant, enhancing the fuse's sensitivity and lifespan. The concealed heating wire layout ensures electrical safety, and the overall structure balances ease of maintenance with operational safety. Attached Figure Description

[0019] 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.
[0020] Please see Figure 1-5This utility model provides a technical solution: a scalding-proof and safe toilet seat heater; specifically, it includes a toilet seat ring 1 and a heating ring 2. A heating wire 3 is fixedly connected to the heating ring 2. The heating wire 3 is heated by electricity and is distributed inside the heating ring 2, which can evenly heat the heating ring 2, thereby transferring heat to the toilet seat ring 1, making the user more comfortable. The toilet seat ring 1 and the heating ring 2 are fixedly connected, which is existing technology and will not be described in detail here. An external safety mechanism is provided at the connection of the heating wire 3. By placing the external safety mechanism on the outside of the toilet seat ring 1, it can be replaced in time in case of overload. This not only ensures timely replacement but also eliminates the need to disassemble the toilet seat ring 1 and the heating ring 2, thus reducing the probability of damage to the connection between the toilet seat ring 1 and the heating ring 2 and improving the overall safety of use. A temperature change mechanism is provided inside the toilet seat ring 1, which can serve as a warning to the user to avoid injury when the temperature is too high.
[0021] The external safety mechanism includes an external box 4, with a cover 5 hinged to the outer end of the external box 4. A sealing ring 6 is fixed to the inner side of the cover 5, preventing water from entering the external box 4. The heating wire 3 is routed into the interior of the external box 4 via a concealed wiring. A fuse 7 is installed inside the external box 4, with the heating wire 3 connected to the fuse 7. The other end of the fuse 7 is connected to the power supply. In case of damage or overload of the heating wire 3, the fuse 7 will melt, thus cutting off the power supply in time and preventing overheating. The external box 4's location on the outside not only facilitates the replacement of the fuse 7 but also prevents it from being damaged by pressure during long-term use, thereby improving the fuse 7's lifespan and sensitivity.
[0022] The temperature-changing mechanism includes color-changing blocks 8, which are fixed to the upper surface of the toilet seat 1. Multiple color-changing blocks 8 are evenly spaced and absorb and monitor the temperature of the toilet seat 1 from multiple angles. The temperature of the color-changing blocks 8 is designed to be set at 40℃. When the temperature exceeds 40℃, the color-changing blocks 8 only change between white and red, immediately turning red above 40℃ to alert the user to the high temperature and prevent burns. Simultaneously, color-changing particles 9 are filled inside the toilet seat 1. The temperature of the color-changing particles 9 is set between 35℃ and 40℃. When the temperature is between 35℃ and 40℃, they produce a slightly reddish color, similarly alerting the user to temperature changes during use.
