Description

Technical Field

[0001] The invention relates to the field of public sanitary ware, and in particular to a method for preventing urine from dripping and a urinal. Background Art

[0002] At present, urinals usually adopt a vertical structure and are widely used in toilets in various public places. When users use urinals to urinate, they are often unwilling to stand too close to the urinals, so they often stand far away from the urinal chamber. As a result, during the process of urinating, especially when the urination is about to end, the user is likely to urinate outside the urinal chamber, and the urine will drip on the ground, making the whole bathroom smelly and requiring regular cleaning by cleaning staff. In addition, it will further aggravate the disgust of the following users towards the urinal, and they will be unwilling to stand in the area where urine is already dripping, and will be more likely to stand back when urinating, which will further aggravate the situation of urine dripping on the ground. In order to maintain hygiene and cleanliness, cleaning staff need to clean frequently.

[0003] At present, many toilets have civilized slogans posted to remind users, such as "A small step forward, a big step towards civilization"; some urinals are designed to be L-shaped, extending the bottom of the chamber as much as possible towards the user, but the effectiveness still depends on the user's personal wishes, and it still cannot achieve a radical effect. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a method for preventing urine dripping and a urinal for preventing urine dripping, which can objectively improve the situation of urine dripping.

[0005] According to a first aspect of an embodiment of the present invention, a method for preventing urine dripping comprises the following steps: providing a toilet body and a baffle, wherein the toilet body has a chamber for collecting urine; detecting a horizontal distance L1 between an obstacle and the front end of the chamber; when the horizontal distance L1 between the obstacle and the front end of the chamber is within a preset range, the baffle opens the chamber; when the horizontal distance L1 between the obstacle and the front end of the chamber is outside the preset range, the baffle closes the chamber.

[0006] At least the following beneficial effects are achieved: the method provides a baffle, and whether the baffle opens or closes the chamber depends on the horizontal distance between the obstacle and the front end of the chamber, which is equivalent to objectively setting a threshold. The obstacle refers to the user. If the horizontal distance between the user and the front end of the chamber is outside the preset range, that is, at a farther position, the chamber is closed by the baffle and the urinal is not in use, forcing the user to stand in a closer area. Only when the horizontal distance between the user and the front end of the chamber is within the preset range, the baffle will open the chamber to provide a place for the user to urinate, thereby effectively preventing urine from dripping on the ground.

[0007] According to some embodiments of the present invention, the preset range is from 10 cm in front of the front end of the chamber to 20 cm behind the front end of the chamber.

[0008] According to a second aspect of the present invention, a urinal for preventing urine from dripping comprises: a urinal body having a chamber for collecting urine; a baffle movably connected to the urinal body and used to close or open the chamber; a power device connected to the baffle and capable of driving the baffle to close or open the chamber; and a distance detection and control system for controlling the action of the power device according to the distance between an obstacle and the distance detection and control system.

[0009] At least the following beneficial effects are achieved: the urinal is provided with a baffle, and the power device can drive the baffle to open or close the chamber. The specific state depends on the distance between the distance detection and control system and the obstacle. Since the distance between the distance detection and control system and the obstacle is usually a horizontal distance, the horizontal distance between the obstacle and the front end of the chamber can be reasonably calculated, which is equivalent to objectively setting a threshold. The obstacle refers to the user. If the user is far away from the front end of the chamber, the urinal is in a non-use state because the chamber is closed by the baffle, forcing the user to stand in a closer area. Only then will the baffle open the chamber to provide a place for the user to urinate, thereby effectively preventing urine from dripping on the ground.

[0010] According to some embodiments of the present invention, the baffle is provided with a piece, and the power device is a motor or a linear drive device, the output end of the motor is rotatably connected to the baffle and can drive the baffle to rotate forward or reversely, or the linear drive device drives the baffle to move back and forth in a straight line.

[0011] According to some embodiments of the present invention, two baffles are provided, and the two baffles are distributed on the left and right.

[0012] According to some embodiments of the present invention, a gear is connected to the upper end of each baffle, and the two gears are meshed with each other. The power device is a motor, and the output end of the motor can drive one of the gears to rotate forward or reverse.

[0013] According to some embodiments of the present invention, four baffles are provided, including two upper baffles symmetrically distributed left and right and two lower baffles symmetrically distributed left and right, and the upper baffles are located above the lower baffles on the same side.

[0014] According to some embodiments of the present invention, the upper baffle is rotatably connected to the lower baffle on the same side, the lower baffle is provided with a slide groove, a limit member is fixedly installed on the toilet body, the slide groove is slidably connected to the limit member, the upper end of each upper baffle is connected to a gear, the two gears are meshed with each other, the power device is a motor, and the output end of the motor can drive one of the gears to rotate forward or reverse.

[0015] According to some embodiments of the present invention, the distance detection and control system includes a distance detection module and a control module, the output end of the distance detection module is electrically connected to the control module, and the control module is electrically connected to the power device.

[0016] According to some embodiments of the present invention, when the distance detection and control system detects that the distance L2 between the obstacle and the distance detection and control system is greater than the preset distance D, the baffle closes the chamber; when the distance detection and control system detects that the distance L2 between the obstacle and the distance detection and control system is less than or equal to the preset distance D, the baffle opens the chamber.

[0025] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0026] In the description of the present invention, it should be understood that the description of the orientation, such as the orientation or position relationship indicated by up, down, front, back, left, right, etc., is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In the description of the present invention, unless otherwise clearly defined, the terms such as setting, installing, connecting, etc. should be understood in a broad sense, and the technical personnel in the relevant technical field can reasonably determine the specific meaning of the above terms in the present invention in combination with the specific content of the technical solution.

[0027] The obstacle in the present invention is not the structure of the present invention. The obstacle is introduced to illustrate the structure and / or function. In real life, the obstacle refers to the user or the user's clothes or other carry-ons. For the convenience of expression and understanding, they are collectively referred to as users. The closure in the present invention is not limited to sealing in a strict sense, but can be understood as closing or closure in human cognition. A closed chamber can be understood as a chamber that is in a state that is not suitable for urination. The above cannot be understood as a limitation of the present invention.

[0028] Reference Figure 1 The present invention discloses a method for preventing urine dripping, comprising the following steps:

[0029] A toilet body 1 and a baffle 3 are provided, wherein the toilet body 1 has a chamber 2 for collecting urine;

[0030] Detect the horizontal distance L1 between the obstacle 4 and the front end of the chamber 2;

[0031] When the horizontal distance L1 between the obstacle 4 and the front end of the chamber 2 is within a preset range, the baffle 3 opens the chamber 2;

[0032] When the horizontal distance L1 between the obstacle 4 and the front end of the chamber 2 is outside the preset range, the baffle 3 closes the chamber 2 .

[0033] In this method, a baffle 3 is provided. Whether the baffle 3 opens or closes the chamber 2 depends on the horizontal distance between the obstacle 4 and the front end of the chamber 2, which is equivalent to objectively setting a threshold. The obstacle refers to the user. If the horizontal distance L1 between the user and the front end of the chamber 2 is outside the preset range, that is, at a farther position, the chamber 2 is closed by the baffle 3 and the urinal is in a non-use state, forcing the user to stand in a closer area. Only when the horizontal distance between the user and the front end of the chamber 2 is within the preset range, the baffle 3 will open the chamber 2 to provide a place for the user to urinate, thereby effectively preventing urine from dripping on the ground.

[0034] Among them, the specific setting of the preset range needs to be considered comprehensively. It can be understood that the preset range should be a suitable range in which urine is not easily dripped when the user stands in the area corresponding to the preset range to urinate. According to actual conditions, urinals can be divided into urinals for children and urinals for adults. Therefore, the preset range itself can be adjusted.

[0035] It can be understood that the reason why the front end of chamber 2 is selected as the benchmark reference point is that chamber 2 itself has a certain horizontal length and is not suitable to be regarded as a point. When the front end of chamber 2 is used as a reference point, when there is still a horizontal distance between the obstacle and the toilet body 1, the front end of chamber 2 is the point where chamber 2 is closest to the obstacle; and after the obstacle exceeds the front end of chamber 2 from front to back, detecting the front end of chamber 2 as a reference point can determine the horizontal distance of the obstacle entering chamber 2.

[0036] In some embodiments of the present invention, the preset range is 10 cm in front of the front end of the chamber to 20 cm behind the front end of the chamber. For further convenience of description, a coordinate system is established with the front end of the chamber 2 as the origin and the front end of the chamber as the positive direction. Considering that the horizontal length of the chamber 2 itself is usually about 20 cm, one of the critical points is selected as -20 cm. At the same time, considering the length of the user's genitals, another critical point is selected as +10 cm, which can better take care of the user's psychological safety distance and greatly improve the urine dripping condition.

[0037] It is understandable that the preset range of the present invention is different from the preset range of a traditional automatic flush urinal. The preset range of a traditional automatic flush urinal is usually much larger than the preset range of the present invention, and the meaning is completely different, and the technical effects achieved are also different.

[0038] How to detect the horizontal distance L1 between the obstacle 4 and the front end of the chamber 2 and how the baffle 3 opens or closes the chamber 2 will be described in detail in the following urinal embodiment.

[0039] Reference Figures 2 to 6 The present invention discloses a urinal for preventing urine from dripping, comprising: a urinal body 1, having a chamber 2 for collecting urine; a baffle 3, movably connected to the urinal body 1, for closing or opening the chamber 2; a power device, connected to the baffle 3, for driving the baffle 3 to close or open the chamber 2; and a distance detection and control system 6, for controlling the action of the power device according to the distance between an obstacle 4 and the distance detection and control system 6.

[0040] It can be understood that the distance detection and control system 6 controls the action of the power device including the action of the power device driving the baffle 3 to close the chamber 2 and the action of the power device driving the baffle 3 to open the chamber 2, wherein the action of the power device driving the baffle 3 to close the chamber 2 includes the dynamic process of the power device driving the baffle 3 to gradually close the chamber 2 and the static maintenance process of the power device after the baffle 3 closes the chamber 2, and the action of the power device driving the baffle 3 to open the chamber 2 includes the dynamic process of the power device driving the baffle 3 to gradually open the chamber 2 and the static maintenance process of the power device after the baffle 3 closes the chamber 2.

[0041] Among them, the specific state of the power device driving the baffle 3 to open the chamber 2 or close the chamber 2 depends on the distance between the obstacle 4 detected by the distance detection and control system 6 and the distance detection and control system 6. Since the distance between the distance detection and control system 6 and the obstacle 4 is usually the horizontal distance between the two, the horizontal distance between the obstacle 4 and the front end of the chamber 2 can be reasonably calculated, which is equivalent to objectively setting a threshold. The obstacle 4 refers to the user. If the user is far away from the front end of the chamber 2, since the chamber 2 is closed by the baffle 3, the urinal is in a non-use state, forcing the user to stand in a closer area, and the baffle 3 will open the chamber 2 to provide a place for the user to urinate, thereby effectively preventing urine from dripping on the ground.

[0042] Specifically, the distance detection and control system 6 in the present invention can be installed on the upper part or above the toilet body 1, and specifically includes a distance detection module and a control module. The output end of the distance detection module is electrically connected to the control module, and the control module is electrically connected to the power device. The distance detection module can be a conventional infrared ranging sensor, and the control module can be a conventional single-chip microcomputer, which will not be described in detail.

[0043] Reference Figure 1For ease of description, it is assumed that the distance detected by the distance detection and control system 6 between the obstacle 4 and the distance detection and control system 6 is L2, L2 is usually the horizontal distance between the obstacle 4 and the distance detection and control system 6, the horizontal distance between the obstacle 4 and the front end of the chamber 2 is L1, and the distance between the front end of the chamber 2 and the control system detection is L0, L2=L0+L1, therefore, the horizontal distance L1 between the obstacle 4 and the front end of the chamber 2 can be reasonably calculated through the distance detection and control system 6, similarly, by reasonably setting the preset range of L1 mentioned above, the preset range of L2 can be reversely deduced.

[0044] In some embodiments of the present invention, the preset range of L2 is L0-20cm to L0+10cm.

[0045] Considering that a smaller critical value in the preset range of L2 may be a negative number, it is discarded and another critical value in the preset range of L2 is set as the preset distance D. The preset distance D is specifically a preset value. When the distance detection and control system 6 detects that the distance L2 between the obstacle 4 and the distance detection and control system 6 is greater than the preset distance D, the control module controls the action of the power device and the baffle 3 closes the chamber 2; when the distance detection and control system 6 detects that the distance L2 between the obstacle 4 and the distance detection and control system 6 is less than or equal to the preset distance D, the control module controls the action of the power device and the baffle 3 opens the chamber 2.

[0046] In other embodiments of the present invention, D=L0. That is, when the user approaches the chamber 2 from front to back, and when the user overlaps with the front end of the chamber 2 or straddles the top of the chamber 2, the baffle 3 opens the chamber 2, and the open end surface of the chamber 2 is inclined, so that the user can straddle the top of the chamber 2 with both legs. The open end surface of the chamber 2 can also be other shapes.

[0047] Regarding the specific arrangement of the baffle 3 and the power device, the urinal of the present invention includes but is not limited to the following three embodiments:

[0048] First embodiment

[0049] The baffle 3 is provided with a piece, and the power device can be a motor or a linear drive device. When the power device is a motor, the motor has three states: forward rotation, reverse rotation and static state. The output end of the motor is rotatably connected with the baffle 3 and can drive the baffle 3 to rotate forward or reversely. The baffle 3 can open the chamber 2 after rotating forward by a certain angle, and the baffle 3 can close the chamber 2 after rotating reversely by a certain angle; when the power device is a linear drive device, the linear drive device of this embodiment is specifically an electric cylinder, and the electric cylinder pushes the baffle 3 to move back and forth in a straight line, so that the baffle 3 can open or close the chamber 2. This embodiment has a simple structure and is easy to operate.

[0050] Second embodiment

[0051] Reference Figure 2 and Figure 3 There are two baffles 3, which are distributed on the left and right. The upper end of each baffle 3 is connected to a gear 7, and the two gears 7 are meshed with each other. The power device is a motor, and the motor has three states: forward rotation, reverse rotation and static state. The output end of the motor can drive one of the gears 7 to rotate forward or reversely, so that the rotation directions of the two gears 7 are opposite.

[0052] When the gear 7 and baffle 3 on the left rotate clockwise, the gear 7 and baffle 3 on the right rotate counterclockwise synchronously, and after rotating a certain angle, the two baffles 3 open the chamber 2; when the gear 7 and baffle 3 on the left rotate counterclockwise, the gear 7 and baffle 3 on the right rotate clockwise synchronously, and after rotating a certain angle, the two baffles 3 close the chamber 2. This embodiment has a simple structure, the baffle 3 occupies a small space, and is easy to operate.

[0053] Third embodiment

[0054] Reference Figure 4 , Figure 5 and Figure 6 The baffle 3 is provided with four pieces, including two upper baffles 31 symmetrically distributed on the left and right and two lower baffles 32 symmetrically distributed on the left and right. The upper baffle 31 is located above the lower baffle 32 on the same side. The upper baffle 31 is rotatably connected with the lower baffle 32 on the same side. In this embodiment, the rotation connection of the upper baffle 31 is located at the outer area of ​​its lower end, and the rotation connection of the lower baffle 32 is located at the outer area of ​​its upper end. The lower baffle 32 is provided with a slide 33. The toilet body 1 is fixedly installed with two limit members 5. The two limit members 5 are distributed in the left and right outer areas of the chamber 2. The limit members 5 can be specifically a rotating pin. The slide 33 is slidably connected with the limit members 5, and the slide 33 is arc-shaped. The upper end of each upper baffle 31 is connected with a gear 7, and the two gears 7 are meshed with each other. The power device is a motor, and the motor has three states: forward, reverse and static. The output end of the motor can drive one of the gears 7 to rotate forward or reverse, so that the two gears 7 rotate in opposite directions.

[0055] When the gear 7 and the upper baffle 31 on the left rotate clockwise, the lower baffle 32 on the left rotates with the rotation connection as the fulcrum and slides outward along the limiter 5. Synchronously, the gear 7 and the upper baffle on the right rotate counterclockwise, and the lower baffle 32 on the right rotates with the rotation connection as the fulcrum and slides outward along the limiter 5, so that the baffle 3 opens the chamber 2; when the gear 7 and the upper baffle 31 on the left rotate counterclockwise, the lower baffle 32 on the left rotates with the rotation connection as the fulcrum and slides inward along the limiter 5. Synchronously, the gear 7 and the upper baffle on the right rotate clockwise, and the lower baffle 32 on the right rotates with the rotation connection as the fulcrum and slides inward along the limiter 5, so that the baffle 3 closes the chamber 2. The baffle 3 of this embodiment occupies very little space and is cleverly designed.

[0056] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
