[0002] In the current third-class toilets, people with mobility impairments need assistance to enter the toilet, but they also desire a certain degree of privacy. The existing third-class toilets are designed as a whole without partitions, resulting in insufficient privacy protection: the light transmittance of traditional frosted glass is fixed and cannot be dynamically adjusted, leading to a lag in emergency response; there is a lack of intelligent features: the current technology of millimeter-wave radar has a low penetration rate, the accuracy of fall detection needs to be improved, and there is a lack of linkage with medical systems.
[0003] Utility model patent CN212656427U discloses a bathroom glass partition, relating to the field of interior decoration technology. Its key technical points are: a bathroom glass partition comprising two parallel glass panels with cavities, and a fixing device for fixing the glass panels; a decorative curtain is installed within the cavity, along with a driving device for raising and lowering the curtain. While this patent can protect privacy, the adjustment method is complex, and it cannot detect if someone has fallen, resulting in low automation.
[0004] Therefore, providing a third type of toilet that can protect privacy and is highly automated is an urgent problem to be solved. Utility Model Content

[0025] 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, not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present utility model.
[0026] The technical concept of this utility model is as follows: The third type of restroom is divided into two parts. People with mobility impairments can operate independently in a privacy cubicle, while their companions wait in a waiting cubicle. The two parts are separated by frosted glass to protect privacy. Radar is used to detect the status of people with mobility impairments, such as whether they have fallen. If an accident occurs in the privacy cubicle, the person in the waiting cubicle can respond in time. This third type of restroom constructs a three-in-one solution of "monitoring-care-interaction" through modular integration innovation.
[0027] This invention provides a third type of restroom. It includes waiting cubicles, privacy cubicles, a guide interaction module for the visually impaired, and frosted glass. The frosted glass divides the restroom into two parts, and privacy is protected by adjusting the light transmittance of the frosted glass. The guide interaction module detects falls, improving safety while protecting privacy. This invention uses both main and auxiliary radars to accurately determine if someone has fallen and whether a cane is being used. It also features tactile guidance and a voice navigation unit, allowing users to enter and exit the restroom with diverse and effective guidance methods. Finally, it includes an emergency button, ensuring manual emergency calls can be made in special circumstances, further enhancing restroom safety.
[0028] Example 1
[0029] like Figure 1 and Figure 2As shown, a third type of restroom includes a waiting cubicle, a privacy cubicle, a control module, a guide interaction module, and a frosted glass 1. The waiting cubicle and the privacy cubicle are separated by the frosted glass 1. The guide interaction module is installed in the waiting cubicle and the privacy cubicle. The control module is communicatively connected to the guide interaction module and the frosted glass 1, respectively.
[0030] The atomizing glass 1 is an electronically controlled dimming glass. The atomizing glass 1 includes a glass interlayer and an electronically controlled dimming film, which is installed within the glass interlayer and is communicatively connected to a control module. The atomizing glass 1 also includes an inner door and an emergency button 3, which is installed in a privacy compartment. The inner door is communicatively connected to both the emergency button 3 and the control module.
[0031] In this embodiment, the frosted glass 1 has an integrated electronically controlled dimming film in the glass interlayer, with a light transmittance adjustable from 5% to 80%; it can dynamically adjust privacy (switching from fully transparent to frosted state in 0.5 seconds). The emergency button 3 is triggered by a pressure sensor and simultaneously pushes GPS location information; the emergency response will be delayed by 1.8 seconds (including the time for the door to automatically unlock).
[0032] The restroom also includes a nursing table 6, a toilet, and a handrail. The nursing table 6, the toilet, and the handrail are all installed in privacy cubicles, and the emergency button 3 is installed on the handrail.
[0033] In this embodiment, the nursing station 6 has the functions of automatic lifting, temperature control, and disinfection.
[0034] The guide interaction module includes a main radar 4 and an auxiliary radar. The main radar 4 is installed at the center of the top of the bathroom, and the auxiliary radar is installed at the bottom of the nursing table. Both the main radar 4 and the auxiliary radar are communicatively connected to the control module. The main radar 4 is installed at an angle.
[0035] In this embodiment, the main radar 4 is a millimeter-wave radar, a 60GHz high-frequency radar, installed at the top center, with a horizontal coverage of 120° × vertical coverage of 60°; the main radar 4 is installed at a height of 2500mm and has a downward viewing angle of 15°. The millimeter-wave radar achieves a fall recognition accuracy of 98.7% (15.7% higher than the traditional method).
[0036] The auxiliary radar is installed below the nursing station. Both the main radar 4 and the auxiliary radar adopt a dual-band working mode (i.e., 24GHz + 60GHz). The bathroom also includes a ventilation device 5, which is connected to the control module. The main radar 4 and the auxiliary radar form a signal linkage with the ventilation device. That is, when someone is detected, the ventilation device 5 is turned on through the control module.
[0037] The main radar 4, auxiliary radar, and cane recognition unit can also identify the position information of the cane.
[0038] The guide interaction module also includes a tactile guide strip 2, which is installed in the waiting compartment and the privacy compartment.
[0039] The guide interaction module also includes a voice navigation unit, which is installed in the waiting compartment and the privacy compartment, and the voice navigation unit is communicatively connected to the control module.
[0040] The guide interaction module also includes a guide cane recognition unit, which is communicatively connected to the control module.
[0041] In this embodiment, the tactile guide strip 2 is a tactile guide strip with a height difference of 3cm (friction coefficient ≥0.85). The tactile guide strip can be integrated with the underfloor heating system to maintain a surface temperature of 28°C. The spacing between the protrusions of the tactile guide strip 2 is 50mm.
[0042] The voice navigation unit is a directional sound field voice navigation system (55-65dB controllable). The voice navigation unit includes a speaker, which is installed at a 15° angle and is 1.2m high. The voice prompt delay is less than 1 second (based on ZigBee protocol transmission).
[0043] The working principle is as follows: the control module can operate automatically. The control process is simple: the control module makes corresponding judgments based on the data from the main radar and auxiliary radar, adjusts the atomizing glass 1, opens the ventilation device 5, controls the voice navigation unit to start, etc. The emergency button 3 can be manually controlled, and can generate an alarm and open the inner door.
[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
