Abstract
Description
Technical Field
[0001] This application relates to the technical field of care cleaning, and particularly to an oral irrigator that prevents damage to a sensing sensor from falling.
Background Art
[0002] An oral irrigator is an auxiliary tool for cleaning the oral cavity, and is a tool that uses the impact of pulsed water flow to clean teeth and tooth gaps. Recently, with the background that personal care and oral care are being increasingly emphasized, the use of oral irrigators has been widely popularized.
[0003] Conventional oral irrigators need to be activated by manually pressing a switch button to generate pulsed water flow during use for oral cleaning, and there is no requirement regarding whether the oral irrigator is in the oral position. However, since high-speed pulsed water flow has a certain amount of kinetic energy, if the direction of the water flow is incorrect or the timing of use is incorrect, there is a risk of accidentally injuring vulnerable parts of the human body such as the eyes. Therefore, in order to achieve safe use through smart technology, several sensors are arranged in the oral irrigator. For example, a distance sensor measures the distance of the user's use distance, and only when it enters the trigger range of the threshold value, the oral irrigator can be used.
[0004] However, when a sensor is attached to an oral irrigator, generally, sensing and contact between the sensor and the outside are realized through a lens. The sensing window of the sensor intersects with a certain location on the lens surface, and this intersection location is likely to be damaged when the oral irrigator falls. Therefore, this application was created in response to this.
Summary of the Invention
Problems to be Solved by the Invention
[0005] The main object of this application is to protect the sensing sensor on the oral irrigator and prevent damage during a fall.
Means for Solving the Problems
[0006] Therefore, the present invention provides an oral irrigator that prevents damage to a sensing sensor from falling. The oral irrigator includes an oral irrigator body, a nozzle that is detachably attached to the ceiling of the oral irrigator body, at least two sensing sensors provided on the ceiling of the oral irrigator body and located on both sides of the nozzle, communicating with a core unit inside the oral irrigator body, and controlling the start / stop state of the core unit by sensing and feeding back information on the distance between the end of the nozzle and the oral cavity, and a fall damage prevention lens provided so as to cover a plurality of the sensing sensors, having protective protrusions, and the elevation of the intersection point with the window of the sensing sensor being lower than the elevation of the protective protrusions.
[0007] Preferably, the nozzle is mounted on the mouth irrigator body in a fixed orientation. There are two sensing sensors. The sensing sensors are located on both sides of the axis of the mouth irrigator body.
[0008] Preferably, the protective projection is located between the two sensing sensors.
[0009] Preferably, the number of sensing sensors is greater than two, and the number of protective protrusions is at least two. The drop-damage prevention lens is provided so as to cover the sensing sensors. The protective protrusions are located between adjacent sensing sensors.
[0010] Preferably, the drop-damage prevention lens has multiple lens surfaces. The multiple lens surfaces adequately cover the sensing sensor. The elevation of the intersection point between the window of the sensing sensor and the lens surface is lower than the elevation of the protective protrusion.
[0011] Preferably, the elevation of the intersection point between the window of each sensing sensor and the lens surface is at least lower than the elevation of the protective projection adjacent to the sensing sensor.
[0012] Preferably, the lens surface has an inclined plane at least at the point where it intersects with the window of the sensing sensor to prevent water droplets from accumulating.
[0013] Preferably, the sensing window of the sensing sensor is deflected toward the user with respect to the axis of the oral irrigator body.
[0014] Preferably, the deflection direction of the sensing window is the same as the direction of the nozzle outlet.
[0015] Preferably, the mouth irrigator body is provided with an insertion port and a nozzle locking mechanism. The nozzle is inserted into the insertion port and locked to the mouth irrigator body by the nozzle locking mechanism. The rotation of the nozzle is restricted between the nozzle and the insertion port or the nozzle locking mechanism by a position regulating unit.
[0016] The position regulating unit includes a position regulating piece and a position regulating groove. The position regulating piece is provided in the insertion port or nozzle locking mechanism, and the position regulating groove is provided in the nozzle. Alternatively, the position regulating piece is provided in the nozzle, and the position regulating groove is provided in the insertion port or the nozzle locking mechanism. [Effects of the Invention]
[0017] The above technical solutions, either individually or in combination, produce the following beneficial effects.
[0018] The drop-resistant lens is designed with protective protrusions. To ensure that the protective protrusions can provide vibration damping and cushioning when the product is dropped, the sensor window is positioned on the lens's surface, so that the protective protrusions make contact with the ground first. As a result, even if the protective protrusions are damaged, the impact on the window on the lens, which is at a lower elevation, is minimal, and the product's window is well protected, so the use of the sensor function is not affected.
[0019] The surface structure of the anti-drop damage lens is special. When the light beam of the sensing sensor passes through the anti-drop damage lens, the inner and outer surfaces of the anti-drop damage lens need to be flat in order to reduce the loss during light transmission. Therefore, at least the intersection of the anti-drop damage lens with the window of the sensing sensor is an inclined plane, which can prevent water droplets from accumulating. The purpose of making the water droplets flow along the inclined plane is to ensure that no extra water droplets remain on the path of the window of the sensor.
[0020] When there are multiple sensing sensors, at least protective protrusions are provided at the locations where each sensing sensor is adjacent to play a protective role.
[0021] The window of the sensing sensor is deflected towards the user side. That is, since the sensor is inclined in the direction of the user, it can capture obstacles better, and obstacle data can be collected in a wider range. If the sensing sensor is in a vertical orientation, when the user stands the oral cleaner upright for use, some data cannot be collected, which will affect the judgment accuracy of the sensor.
[0022] The nozzle is fixed in one direction and is in the same direction as the inclination direction of the sensing sensor. Thereby, the sensing sensor can detect the user's usage state better, so the accuracy of data collection is guaranteed. Also, compared with the case where the nozzle is rotatable, it is not necessary to detect with multiple sensors, so the usage cost is reduced, the accuracy of data collection is improved, and the risk is reduced.

MODE FOR CARRYING OUT THE INVENTION
[0024] The preferred embodiments described below are merely illustrative, and those skilled in the art can conceive other obvious modifications. The basic principles of the present application defined in the following description can be applied to other implementation schemes, modification schemes, improvement schemes, equivalent schemes, and other technical schemes that do not deviate from the spirit and scope of the present application.
[0025] As should be understood by those skilled in the art, in the disclosure of the present application, the directions or positional relationships indicated by terms such as "vertical direction", "horizontal direction", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "ceiling", "bottom", "inside", "outside", etc. are the directions or positional relationships based on the illustration, and are only for the convenience of description and simplification of the description of the present application, and do not expressly or implicitly imply that the target device or member must have a specific direction and be configured and operated in a specific direction. Therefore, the above terms should not be construed as limiting the present application.
[0026] This embodiment provides an oral irrigator that prevents drop damage to the sensing sensor. Here, "preventing drop damage to the sensing sensor" is defined as preventing damage to the sensing sensor in the oral irrigator during dropping or falling. Further, the "damage" mainly refers to the damage received at the intersection 321 between the window 41 of the sensing sensor on the drop damage prevention lens 3 of the oral irrigator. More comprehensively stated, the "damage" refers to the damage received by the lens surface 32 covering the sensing sensor.
[0027] In this embodiment, the oral irrigator that prevents damage to the sensing sensor from falling includes an oral irrigator body 1, a sensing sensor, and a fall damage prevention lens 3. The sensing sensor is provided on the oral irrigator body 1. The sensing sensor communicates with a core unit inside the oral irrigator body 1 and controls the start / stop state of the core unit by sensing and feeding back information. Specifically, the sensing sensor can be an infrared distance sensor or a light intensity sensor and is connected to a control member of the core unit inside the oral irrigator (generally connected to a circuit). When the sensing sensor detects entry into the oral cavity or approach to the user, it feeds back information to the core unit of the oral irrigator. As a result, the core unit enters an operating state, and the user can perform oral irrigation by pressing the switch on the oral irrigator.
[0028] Taking an infrared distance sensor as an example, the sensor controls the activation / deactivation of the oral irrigator by sensing and feeding back information about the distance between the tip of the nozzle and the oral cavity. When a user picks up the oral irrigator and extends the nozzle into their oral cavity, if the infrared distance sensor measures and senses that the distance between the tip of the nozzle and the sensor is blocked by the oral cavity, the oral irrigator may operate normally. However, if the opposite is true, it may not operate.
[0029] By a similar principle, in the case of a light intensity sensor, if the collection of light intensity weakens when the user picks up the mouth irrigator and brings the nozzle close to the mouth, the mouth irrigator will receive feedback and operate normally. However, it cannot operate unless the change in light intensity within a certain period exceeds a threshold.
[0030] The above-described sensor technology is prior art, and the explanation provided here is necessary as a prerequisite for describing and understanding this application. However, this embodiment does not relate to any technical improvements to the operating principle or other aspects of the sensor, and therefore will not be described in further detail.
[0031] Referring to Figures 1 to 7, the mouth irrigator body 1 is provided with mounting grooves, and at least two sensing sensors are provided within the mounting grooves. The drop damage prevention lens 3 is provided so as to cover the sensing sensors. The drop damage prevention lens 3 has protective protrusions 31. The elevation of the intersection point 321 between the sensing sensor window 41 and the drop damage prevention lens 3 is lower than the elevation of the protective protrusions 31. In this embodiment, "elevation" is interpreted as the elevation relative to a reference plane. For example, if the mouth irrigator body is located on a horizontal table, the elevation is the relative height difference between the structure (protective protrusions 31 or intersection point 321) and the reference plane.
[0032] The number of sensing sensors may be one or multiple. In this embodiment, there are at least two sensing sensors, and at least two sensing sensors are arranged side by side. Preferably, the two sensing sensors are provided symmetrically with respect to the nozzle 2 on the oral irrigator body 1 and are located on both sides of the nozzle 2.
[0033] In a preferred embodiment of this design, when there are two sensing sensors, the drop damage prevention lens 3 is provided so as to cover the sensing sensors, and the protective projection 31 is positioned between the two sensing sensors. Specifically, in this case, the drop damage prevention lens 3 is integrally formed by two drop damage prevention lens plates, one on the left and one on the right, with the protective projection 31 formed between them.
[0034] In a preferred embodiment of this design, if the number of sensing sensors is greater than two, the number of protective protrusions 31 will be at least two. Furthermore, the drop damage prevention lens 3 is provided so as to cover the sensing sensors, and the position of the protective protrusions 31 is between adjacent sensing sensors. For example, suppose there are three sensing sensors and the drop damage prevention lens 3 is provided so as to cover the sensing sensors. Specifically, in this case, the drop damage prevention lens 3 is integrally constructed from three drop damage prevention lens plates, left, center, and right, and the protective protrusions 31 are formed between two adjacent lens plates.
[0035] As described above, the drop damage prevention lens 3 has multiple lens surfaces 32 (generally, one lens surface 32 corresponds to each lens plate). The multiple lens surfaces 32 cover the sensing sensor accordingly. The intersection 321 of the sensing sensor window 41 and its corresponding lens surface 32 can be protected if its elevation is lower than the elevation of the protective projection 31.
[0036] Regardless of whether there is one or more sensing sensors, as described above, the elevation of the intersection point 321 between the window 41 of each sensing sensor and its corresponding lens surface 32 is lower than, at least, the elevation of the protective projection 31 adjacent to that sensing sensor. In this way, each lens surface 32 can be protected by at least the nearest protective projection 31.
[0037] Furthermore, the lens surface 32 has an inclined plane at least at the intersection 321 with the window 41 of the sensing sensor to prevent water droplets from accumulating. In practice, it is easiest to implement if the entire lens surface 32 is an inclined plane. This prevents water droplets from remaining on the inclined plane, thus preventing false detections by the sensing sensor.
[0038] To better detect obstacles and collect obstacle data over a wider area, the sensing window 41 is deflected towards the user with respect to the axis of the oral irrigator body 1. This allows the sensing sensor to collect data more accurately than when it is oriented vertically, when the user brings the device close to their mouth.
[0039] Furthermore, a nozzle 2 is attached to the oral irrigator body 1. The nozzle outlet 21 of nozzle 2 faces the user, and the deflection direction of the sensing window 41 is the same as the direction of the nozzle outlet 21. Nozzle 2 is fixed in one direction and is oriented in the same direction as the tilt direction of the sensing sensor. This allows the sensing sensor to detect the user's usage state more effectively, thus guaranteeing the accuracy of data collection. In addition, compared to a case where nozzle 2 is rotatable, there is no need for detection by multiple sensors (because people naturally adjust the nozzle to fit their mouth as a matter of habit, so if the direction of nozzle 2 changes, a sensor is required at the location corresponding to the mouth), which reduces operating costs, improves the accuracy of data collection, and lowers risks.
[0040] The nozzle 2 is primarily attached by insertion. This makes it easy to change the model number of the nozzle 2. Specifically, the oral irrigator body 1 is provided with an insertion port 12. The nozzle 2 is inserted into the insertion port 12 and locked to the oral irrigator body by a nozzle locking mechanism. The rotation of the nozzle 2 is restricted between the nozzle 2 and the insertion port 12 or the nozzle locking mechanism by a position regulating unit.
[0041] The position regulating unit includes a position regulating piece 121 and a position regulating groove 22. There are two embodiments of the configuration of the position regulating piece 121 and the position regulating groove 22.
[0042] 1. A position regulating piece 121 is provided in the insertion port 12 or the nozzle locking mechanism, and a position regulating groove 22 is provided in the nozzle 2.
[0043] 2. A position regulating piece 121 is provided on the nozzle 2, and a position regulating groove 22 is provided in the insertion port 12 or the nozzle locking mechanism.
[0044] It should be made clear that the nozzle locking mechanism of an oral irrigator is a common mechanism in the field of oral irrigators, and various design forms exist, with many of the principles being in the form of hooks, etc., but the structure will not be described in detail here. The technical solution of this embodiment is not related to any improvement of the nozzle mounting principle. The purpose of introducing the nozzle locking mechanism is to briefly illustrate the nozzle mounting form, and this point should be understood without doubt by those skilled in the art.
[0045] The above technical solutions, either individually or in combination, produce the following beneficial effects.
[0046] The drop-resistant lens 3 is structurally designed with protective protrusions 31. To ensure that the protective protrusions 31 can provide vibration damping and cushioning when the product is dropped, the sensing sensor window 41 is located on the surface of the lens, and the protective protrusions 31 make contact with the ground first when the product is dropped. As a result, even if the protective protrusions 31 are damaged, the impact on the window 41 on the lens, which is at a lower elevation, is small, and the window 41 of the product is well protected, so the use of the sensing sensor function is not affected.
[0047] The surface structure of the drop-damage prevention lens 3 is special. When the light ray from the sensing sensor passes through the drop-damage prevention lens 3, the inner and outer surfaces of the drop-damage prevention lens 3 need to be flat in order to reduce loss during light ray transmission. For this reason, the drop-damage prevention lens 3 has an inclined plane at least at the intersection 321 with the window 41 of the sensing sensor, which prevents water droplets from accumulating. The purpose of allowing water droplets to flow along the slope is to ensure that no excess water droplets remain on the path of the sensor window 41.
[0048] If there are multiple sensing sensors, protective protrusions 31 are provided at least at the locations adjacent to each sensing sensor to provide protection.
[0049] The sensing sensor's window 41 is biased towards the user. That is, because the sensor is tilted towards the user, it can better detect obstacles and collect obstacle data over a wider range. If the sensing sensor were oriented vertically, some data would not be collected when the user uses the mouthwash upright, affecting the accuracy of the sensor's detection.
[0050] Nozzle 2 is fixed in one direction and oriented in the same direction as the tilt of the sensing sensor. This allows the sensing sensor to detect the user's usage status more effectively, thus ensuring the accuracy of data acquisition. Furthermore, compared to a case where nozzle 2 is rotatable, the need for detection by multiple sensors is eliminated, resulting in lower operating costs, improved data acquisition accuracy, and reduced risk.
[0051] Those skilled in the art should understand that the embodiments of the present application described above are merely illustrative and not limiting. The objectives of the present application are fully and effectively achieved. Furthermore, although the principles of the function and structure of the present application have been presented and explained in the embodiments, any modifications or alterations to the embodiments of the present application are permitted as long as they do not deviate from the aforementioned principles.
