At present, in order to prevent the swimming cap from hitting the wall of the swimming pool during swimming, particularly diving, a protective structure is usually added on the swimming cap to protect the head, for example, the thickness of the top of the cap is increased. In addition, for the swimming of the blind, it is now common for someone else to be guided by a guide rod at the side in order to prevent the blind from hitting the wall of the swimming pool. However, these approaches either protect the user after the collision has occurred or require assistance from others to prevent the collision, and do not satisfy the need for early collision avoidance when a single person swims.

Please refer to fig. 1, which is a functional block diagram of a swimming cap 100 according to an embodiment of the present application. The swimming cap 100 comprises a distance sensor 1, an output unit 2 and a controller 3. The distance sensor 1 is used to sense the distance between a target object outside the swimming cap 100 and the swimming cap 100. The controller 3 is used for controlling the output unit 2 to generate a prompt signal when the distance sensed by the distance sensor 1 is less than or equal to a preset distance.
Therefore, in the present application, when the user swims by wearing the swimming cap 100 on his head, the distance between the target object outside the swimming cap 100 and the swimming cap 100 is sensed by the distance sensor 1, and when the sensed distance is less than or equal to the preset distance, the control output unit 2 generates the prompt signal to prompt the user to avoid or turn around before touching the target object, so that the user can swim alone to avoid colliding with the target object such as the pool wall of the swimming pool.
The swimming cap 100 further comprises a pressure sensor 4 for sensing the outside pressure of the swimming cap 100. The controller 3 is further configured to control the distance sensor 1 to be activated to sense a distance between a target object outside the swimming cap 100 and the swimming cap 100 when the pressure sensed by the pressure sensor 4 is greater than or equal to a preset pressure.
The controller 3 is further configured to control the distance sensor 1 to be turned off when the pressure sensed by the pressure sensor 4 is less than the preset pressure.
Thus, in this application, just control distance sensor 1 and start when pressure that pressure sensor 4 sensing was greater than or equal to predetermines pressure to, can just start distance sensor 1 when guaranteeing that the user received the pressure of water when swimming in the swimming pool, when pressure is less than predetermine pressure, explain that user's head did not get into the aquatic this moment, steerable distance sensor 1 closes this moment, has avoided distance sensor 1 to open always, has saved the electric energy.
In some embodiments, when the distance sensed by the distance sensor 1 is less than or equal to the preset distance, the controller 3 controls the output unit 2 to generate a prompt signal, which may specifically include: the controller 3 controls the output unit 2 to generate a first prompt signal when the distance sensed by the distance sensor 1 is less than or equal to a first preset distance, and controls the output unit 2 to generate a second prompt signal when the distance sensed by the distance sensor 1 is less than or equal to a second preset distance, wherein the second preset distance is less than the first preset distance.
Therefore, the user can be effectively reminded by reminding for multiple times in stages.
In some embodiments, the first predetermined distance may be 8 meters and the second predetermined distance may be 5 meters. Obviously, in other embodiments, the first preset distance and the second preset distance may have other suitable values, for example, the first preset distance may be 6 meters, the second preset distance may be 3 meters, and so on.
Obviously, in some embodiments, the reminding may be only once, that is, the preset distance is 5 meters, and the controller 3 controls the output unit 2 to generate the prompt signal when the distance sensed by the distance sensor 1 is less than or equal to the preset distance, for example, 5 meters.
In some embodiments, the time length of the control output unit 2 generating the prompt message may last for a preset time, for example, when the prompt message is generated once, the prompt message may last for 5 seconds, when the prompt message is generated twice, the first prompt message and the second prompt signal may last for 5 seconds, or the first prompt message may continue to be generated when the distance sensed by the distance sensor 1 is between the first preset distance and the second preset distance, so that the prompt message may be generated for a longer time, and the user may be effectively reminded.
Referring to fig. 2, it is a schematic diagram of an output unit 2 in an embodiment, as shown in fig. 2, the output unit includes a vibrator 21, the first prompt signal is a vibration prompt signal with a first intensity, the second prompt signal is a vibration prompt signal with a second intensity, and the second intensity is greater than the first intensity. Wherein the vibrator 21 is a buzzer or the like.
Thus, when the distance sensed by the distance sensor 1 is less than or equal to the first preset distance but greater than the second distance, the vibrator 21 generates a vibration alert signal of lower intensity, and as it comes closer to the target object, that is, when the distance sensed by the distance sensor 1 is less than or equal to the second preset distance, the vibrator 21 will generate a vibration alert signal of higher intensity, thereby giving a stronger alert to the user.
Fig. 3 is a schematic diagram of an output unit 2 according to another embodiment. The output unit 2 comprises a sound output unit 22, the first prompt signal is a sound prompt signal with a first volume, the second prompt signal is a sound prompt signal with a second volume, and the second volume is greater than the first volume.
Thus, when the distance sensed by the distance sensor 1 is less than or equal to the first preset distance and greater than the second preset distance, the vibrator 21 generates a lower volume of the audible cue signal, and as the target object is closer, that is, when the distance sensed by the distance sensor 1 is less than or equal to the second preset distance, the vibrator 21 generates a higher volume of the audible cue signal, thereby giving a stronger reminder to the user.
The voice prompt signal may be a simple sound such as a droplet, a beep, etc., or may include preset voice content, for example, a voice prompt signal including voice content "please notice an obstacle ahead".
The sound output unit 22 may be a sound output device such as a speaker.
Fig. 4 is a schematic diagram of an output unit 2 according to yet another embodiment. In yet another embodiment, the output unit 2 may include both the vibrator 21 and the sound output unit 22. The first cue signal may simultaneously include a vibration cue signal having a first intensity and an audible cue signal having a first volume, and the second cue signal may simultaneously include a vibration cue signal having a second intensity and an audible cue signal having a second volume.
Therefore, the vibration prompt signal and the sound prompt signal are generated simultaneously, the user can be reminded more assuredly, and the reminding success rate is improved.

The power switch 6 may be a MOS transistor Q1, a drain and a source of the MOS transistor Q1 are electrically connected to the power supply 5 and the distance sensor 1, respectively, a gate of the MOS transistor Q1 is connected to the controller 3, and the controller 3 is configured to output a corresponding level signal to control the MOS transistor Q1 to be turned on or off. For example, the MOS transistor Q1 may be an NMOS transistor, the controller 3 outputs a high level signal to the gate of the MOS transistor Q1 to control the MOS transistor Q1 to be turned on when the pressure sensed by the pressure sensor 4 is greater than or equal to a preset pressure, and the controller 3 outputs a low level signal to the gate of the MOS transistor Q1 to control the MOS transistor Q1 to be turned off when the pressure sensed by the pressure sensor 4 is less than the preset pressure.
