Description

Technical Field

[0001] This utility model belongs to the field of sanitary ware technology, and specifically relates to a toilet pedal. Background Technology

[0002] Children are too short to sit on adult toilets, and their feet cannot touch the ground when they sit on the toilet, making them prone to losing their balance and falling. As a result, children need adult assistance to use the toilet.

[0003] The current solution is to place a toilet stool in front of the toilet, but the height of the toilet stool is fixed and cannot meet the needs of children at different stages of growth. Utility Model Content

[0004] The purpose of this utility model is to provide a toilet pedal to solve the technical problems of children's inability to use the toilet independently, fixed toilet stool height, and low applicability in the prior art.

[0005] The technical solution adopted to solve the above-mentioned technical problems is as follows:

[0006] This utility model discloses a toilet pedal, comprising:

[0007] The pedal body includes an upper outer cover and a lower outer cover that are telescopically configured;

[0008] The lifting mechanism includes a first lifting end and a second lifting end that are lifted relative to each other. The first lifting end is connected to the upper outer cover, and the second lifting end is connected to the lower outer cover.

[0009] The controller is electrically connected to the lifting mechanism, which causes the pedal body to retract into a stowage state or extend into working states at different heights. The controller is electrically connected to a wireless communication component.

[0010] The present invention has at least the following beneficial effects: The pedal body includes an upper outer cover and a lower outer cover, which are telescopically designed to allow the lifting mechanism and controller to be concealed within them, facilitating safe use by children, preventing pinching injuries, and improving the aesthetics of the toilet pedal. The lifting mechanism includes a first lifting end and a second lifting end that lift relative to each other. Since the first lifting end is connected to the upper outer cover and the second lifting end is connected to the lower outer cover, when the lifting mechanism is activated, the relatively lifting first and second lifting ends drive the upper and lower outer covers to lift relative to each other, thereby extending the pedal body relative to each other, increasing the height of the toilet pedal, making it easier for younger children to use. This allows children to use the toilet independently and autonomously via the toilet pedal, which provides stable support for children and prevents them from falling while using the toilet.

[0011] The relatively adjustable first and second lifting ends also allow for relative retraction of the pedal body, lowering the toilet pedal height. This makes the toilet pedal adjustable according to a child's age and leg length, ensuring it is suitable for children of different ages and improving its usability. Furthermore, adults can use the toilet pedal to simulate a squatting posture, increasing the anorectal angle formed by the rectum and rectum, more closely resembling a natural defecation angle, thus aiding in smoother bowel movements. When the pedal body is retracted to its lowest position, the toilet pedal height is at its lowest, preventing it from taking up bathroom space and reducing the possibility of tripping.

[0012] The controller and lifting mechanism are electrically connected. The controller is equipped with a wireless communication component, allowing children and adults to operate the controller via wireless signals emitted by devices such as remote controls. This enables the controller to drive the lifting mechanism and adjust the working or storage states at different heights, making it convenient to use.

[0013] As a further improvement to the above technical solution, the lifting mechanism includes a scissor lift assembly, a drive assembly, an upper mounting base, and a lower mounting base. The scissor lift assembly includes two hinged scissor arms, with a fixed end and a movable end at each end. The two fixed ends are vertically aligned and rotatably connected to the upper mounting base and the lower mounting base, respectively. The two movable ends are vertically aligned and slidably connected to the upper mounting base and the lower mounting base, respectively. The output end of the drive assembly moves linearly along a first direction and is rotatably connected to one of the movable ends. The first lifting end is the upper mounting base, and the second lifting end is the lower mounting base.

[0014] As a further improvement to the above technical solution, the drive assembly includes a geared motor, a lead screw, a nut seat, and a linkage rod. The output end of the geared motor extends along a first direction and is connected to the lead screw via a transmission. The lead screw extends along the first direction and its two ends are rotatably connected to the lower mounting base. The nut seat is threaded onto the lead screw and is connected to the linkage rod. The linkage rod extends along a second direction, and one end of the linkage rod is rotatably connected to one of the movable ends of a scissor lift assembly. The other end of the linkage rod is rotatably connected to one of the movable ends of another scissor lift assembly. The second direction is a horizontal direction perpendicular to the first direction.

[0015] As a further improvement to the above technical solution, the linkage rod is connected to a sensing rod, and the lower mounting base is provided with a first sensing element and a second sensing element that are electrically connected to the controller. The first sensing element and the second sensing element are spaced apart along a first direction.

[0016] When the sensing rod is in contact with the first sensing element, the controller shuts down the lifting mechanism, and the pedal body is in a retracted state.

[0017] When the sensing rod and the second sensing element are in contact, the controller shuts down the lifting mechanism, and the pedal body is in the highest working position.

[0018] As a further improvement to the above technical solution, rolling bearings are respectively connected to both ends of the linkage rod, and the two rolling bearings are tactilely connected to the lower mounting base.

[0019] As a further improvement to the above technical solution, the two movable ends located at the top are rotatably connected to a connecting shaft, and the two ends of the connecting shaft are respectively connected to rolling bearings, and the two rolling bearings are rotatably connected to the upper mounting base.

[0020] As a further improvement to the above technical solution, the upper mounting base is provided with two limiting seats, the lower mounting base is provided with two limiting seats, the limiting seats form a limiting channel extending along a first direction, and the rolling bearing rolls within the limiting channel.

[0021] As a further improvement to the above technical solution, the scissor lift assembly also includes a pin and a lock nut. The scissor lift arm has a pin hole in the middle, and the pin passes through the two pin holes and is connected to the lock nut.

[0022] As a further improvement to the above technical solution, the upper outer cover is larger than the lower outer cover, and when the pedal body is in the retracted state, the lower outer cover is embedded in the upper outer cover.

[0023] As a further improvement to the above technical solution, the upper outer cover and the lower outer cover are respectively provided with anti-slip components. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0045] In the description of this utility model, the use of terms such as "several" means one or more, with "multiple" meaning two or more. Terms like "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number.

[0046] It should be noted that in the attached diagram, the X direction points from the back of the toilet pedal to the front; the Y direction points from the left side of the toilet pedal to the right; and the Z direction points from the bottom of the toilet pedal to the top.

[0047] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0048] Reference Figures 1 to 9 The following are several embodiments of the toilet pedal of this utility model.

[0049] like Figures 1 to 9 As shown, the toilet pedal 100 of this utility model embodiment includes a pedal body, a lifting mechanism and a controller.

[0050] It is understood that the pedal body includes an upper outer cover 210 and a lower outer cover 220 with telescopic configuration, such as Figures 1 to 3 As shown. Specifically, the upper outer cover 210 has a first mounting cavity 211 with its opening facing downwards, and the lower outer cover 220 has a second mounting cavity 221 with its opening facing upwards, as shown. Figure 3 As shown, the lifting mechanism is concealed within the first mounting cavity 211 and the second mounting cavity 221.

[0051] It is understood that the lifting mechanism includes a first lifting end and a second lifting end that are relatively lifted. The first lifting end is connected to the upper outer cover 210, and the second lifting end is connected to the lower outer cover 220. When the lifting mechanism is started, the first lifting end and the second lifting end drive the upper outer cover 210 and the lower outer cover 220 to extend and retract relative to each other in the vertical direction, thereby adjusting the height of the pedal body.

[0052] Understandably, the controller and lifting mechanism are electrically connected, allowing users to control the lifting mechanism's switching and reversing to adjust the height of the toilet pedal. The controller is also electrically connected to a wireless communication component, which can receive infrared, Bluetooth, WiFi, and other wireless signals from wireless remote controls, central control screens, or other electronic devices, facilitating simple and quick adjustment of the toilet pedal height.

[0053] It is understood that the toilet pedal body has a retracted state and an operating state. When the toilet pedal body is in the retracted state, the controller activates the lifting mechanism, causing the upper outer cover 210 and lower outer cover 220 to retract, minimizing the height of the toilet pedal body. This reduces its footprint in the bathroom when the toilet pedal 100 is not in use, reducing the possibility of tripping. When the toilet pedal body is in the operating state, the controller activates the lifting mechanism, causing the upper outer cover 210 and lower outer cover 220 to extend, adjusting the height of the toilet pedal body. The toilet pedal body has different operating heights, allowing it to be adjusted to a suitable height according to the user's needs, improving the usability of the toilet pedal 100.

[0054] Understandably, the toilet footrest 100 can be set to the height of the working state according to the child's height. The child can climb onto the toilet by stepping on the toilet footrest 100. When sitting on the toilet, the child's feet are placed on the toilet footrest 100, which helps the child maintain balance and prevents them from falling into the toilet or falling to the ground.

[0055] Understandably, since children grow taller quickly, the height of the toilet footrest 100 can be adjusted according to the height of children at different stages of growth to meet their usage needs.

[0056] Understandably, the height of the toilet pedal 100 can be adjusted to suit the needs of adults. When adults use the toilet pedal 100, it raises the position of the pelvic floor, simulating a squatting posture, which increases the anorectal angle formed by the rectal muscles and rectum, making it closer to the natural defecation angle, thus helping to facilitate smooth defecation.

[0057] Understandably, the controller includes a storage mode, a child mode, and an adult mode. When the user activates the storage mode via a wireless remote control or other device, the controller activates the lifting mechanism, causing the toilet pedal to automatically retract into its storage position. After adjusting the pedal to a child's or adult's height using the controller and lifting mechanism, the user saves the height and names it "Child Mode" and "Adult Mode," respectively. Different users can directly select the corresponding child or adult mode on their wireless device. The wireless communication component receives the information and sends it to the controller, which then activates the lifting mechanism to automatically extend or retract to the saved child or adult height. This eliminates the need to repeatedly adjust the toilet pedal height each time, improving user convenience.

[0058] It is understood that the controller can be a microcontroller or a PCL controller, capable of simply controlling the lifting mechanism. It should be noted that the control method of the controller is not within the scope of this utility model and belongs to existing technology. This utility model primarily protects the connection method of the controller.

[0059] In some embodiments, the lifting mechanism can be a linear motion mechanism such as a cylinder, hydraulic cylinder, or electric cylinder. Taking a cylinder as an example, the output end of the cylinder is the first lifting end, and the cylinder is the second lifting end. When the cylinder is started, the upper outer cover 210 and the lower outer cover 220 extend and retract in the vertical direction.

[0060] In this embodiment, the lifting mechanism includes a scissor lift assembly 400, a drive assembly 500, an upper mounting base 310, and a lower mounting base 320, as follows: Figure 3 and Figure 5 As shown. The first lifting end is the upper mounting base 310, and the second lifting end is the lower mounting base 320. That is, the upper mounting base 310 is connected to the upper outer cover 210, and the lower mounting base 320 is connected to the lower outer cover 220, as shown. Figure 3 As shown.

[0061] It is understood that the scissor lift assembly 400 includes two scissor lift arms 450, which are hinged together, such as... Figure 7 As shown. The two ends of the scissor arm 450 are a fixed end 410 and a movable end 420, respectively. Figure 3 As shown, two fixed ends 410 are positioned vertically opposite each other. One fixed end 410 is rotatably connected to the upper mounting base 310, and the other fixed end 410 is rotatably connected to the lower mounting base 320. Two movable ends 420 are positioned vertically opposite each other. One movable end 420 is slidably connected to the upper mounting base 310, and the other movable end 420 is slidably connected to the lower mounting base 320, so that the two movable ends 420 can obtain support from the upper mounting base 310 and the lower mounting base 320 respectively.

[0062] It is understood that the output end of the drive assembly 500 moves linearly along the first direction. The output end of the drive assembly 500 is rotatably connected to one of the movable ends 420 of the scissor lift assembly 400. When the drive assembly 500 is activated, its output end drives one of the movable ends 420 to move linearly along the first direction, thereby changing the relative angle between the two scissor lift arms 450, realizing the up-and-down movement of the upper mounting base 310 and the lower mounting base 320, and thus achieving the state switching of the pedal body. In this embodiment, the first direction is the front-to-back direction.

[0063] Understandably, the scissor lift assembly 400 has a simple structure and high stability, effectively distributing and transferring loads to achieve smooth and precise lifting of the upper mounting base 310 and the lower mounting base 320.

[0064] It is understood that in the scissor lift assembly 400, the upper fixed end 410 and the upper movable end 420 are arranged at intervals along a first direction and are at the same horizontal position. In this embodiment, the movable end 420 is located in front of the fixed end 410.

[0065] It is understandable that two scissor lift assemblies 400 are provided and spaced apart along a second direction, which is a horizontal direction perpendicular to the first direction. That is, the two scissor lift assemblies 400 are spaced apart to further improve the stability of the pedal body.

[0066] In this embodiment, the drive assembly 500 includes a geared motor 510, a lead screw 520, a nut seat 530, and a linkage rod 540, such as... Figure 6 As shown. Specifically, the geared motor 510 is fixedly connected to the lower mounting base 320 via a connecting seat 511. The output end of the geared motor 510 extends along a first direction, and the output end of the geared motor 510 and the lead screw 520 are connected via a coupling. The lead screw 520 extends along the first direction, and both ends are rotatably connected to the connecting seat 511 via bearing seats 521. A nut seat 530 is sleeved on the lead screw 520, and the nut seat 530 is connected to the linkage rod 540. The linkage rod 540 extends along a second direction, and one end of the linkage rod 540 is rotatably connected to the lower movable end 420 of a scissor lift assembly 400 via a bearing, and the other end of the linkage rod 540 is rotatably connected to the lower movable end 420 of another scissor lift assembly 400 via a bearing.

[0067] With this configuration, when the geared motor 510 starts, the geared motor 510 drives the lead screw 520 to rotate along the axis in the front-back direction. Through threaded engagement, the nut seat 530 and its connected linkage rod 540 are forced to move back and forth, thereby driving the two movable ends 420 of the two scissor fork assemblies 400 located below to move back and forth, thus realizing the lifting adjustment.

[0068] Furthermore, the linkage rod 540 is connected to a sensing rod 600, which extends along a first direction. A first sensing element 610 and a second sensing element 620 are provided on the lower mounting base 320. The first sensing element 610 and the second sensing element 620 are electrically connected to the controller, and the first sensing element 610 and the second sensing element 620 are spaced apart along the first direction. Figure 3 As shown.

[0069] Understandably, the first sensor 610 is located in front of the second sensor 620. When the output end of the geared motor 510 drives the linkage rod 540 and the two movable ends 420 to move forward, the distance between the movable end 420 and the fixed end 410 gradually increases, and the height of the toilet pedal 100 gradually decreases until the sensor rod 600 and the first sensor 610 are in contact. The first sensor 610 sends a signal to the controller. After receiving the signal, the controller turns off the geared motor 510. At this time, the distance between the upper mounting base 310 and the lower mounting base 320 is small, and the pedal body is in a retracted state.

[0070] Understandably, when the output end of the geared motor 510 drives the linkage rod 540 and the two movable ends 420 to move backward, the distance between the movable end 420 and the fixed end 410 gradually decreases, and the height of the toilet pedal 100 gradually increases until the sensing rod 600 and the second sensing element 620 are connected. The second sensing element 620 sends a signal to the controller. After receiving the signal, the controller turns off the geared motor 510. At this time, the distance between the upper mounting base 310 and the lower mounting base 320 is large, and the pedal body is in the highest working position.

[0071] With this configuration, the forward and backward movement range of the linkage rod 540 is limited by the sensing rod 600, the first sensing element 610, and the second sensing element 620, thereby limiting the rise and fall of the toilet pedal 100 between the retracted state and the working state at the highest position, and preventing the rise and fall range of the toilet pedal 100 from exceeding the limit and damaging the structure.

[0072] It is understood that the first sensing element 610 and the second sensing element 620 can be proximity switches, photoelectric sensors, or limit switches, etc. In this embodiment, the first sensing element 610 and the second sensing element 620 are limit switches.

[0073] It is understandable that rolling bearings 460 are respectively connected to both ends of the linkage 540 along the second direction. The outer end face of the rolling bearing 460 is in rolling connection with the upper end face of the lower mounting base 320, thereby realizing the sliding connection between the two movable ends 420 and the lower mounting base 320. Figure 4 As shown.

[0074] It is understood that the two upper movable ends 420 are rotatably connected to the connecting shaft via rolling bearings 460, so that the two upper movable ends 420 are linked together. The connecting shaft extends along the second direction, realizing the sliding connection between the two upper movable ends 420 and the upper mounting base 310.

[0075] Furthermore, the upper mounting base 310 is provided with two limiting seats 700 corresponding to the positions of the two rolling bearings 460, such as... Figure 8 As shown. The lower mounting base 320 also has two limiting seats 700 corresponding to the positions of the two rolling bearings 460, as... Figure 9 As shown. The limiting seat 700 forms a limiting channel 720, which extends along the first direction. The rolling bearing 460 rolls within the limiting channel 720. The limiting seat 700 is used to limit the rolling position of the rolling bearing 460, ensuring that the movable end 420 only slides back and forth along the first direction.

[0076] In this embodiment, each limiting seat 700 includes two limiting plates 710 spaced apart from each other. The upper limiting channel 720 is formed by the two limiting plates 710 and the lower end face of the upper mounting seat 310, and the lower limiting channel 720 is formed by the two limiting plates 710 and the upper end face of the lower mounting seat 320. Figure 5 As shown.

[0077] Understandably, the scissor lift assembly 400 also includes a pin 441 and a lock nut 442. Each scissor lift arm 450 has a pin hole 430 in the middle. The pin 441 passes through the two pin holes 430 of the two scissor lift arms 450 and is threadedly connected to the lock nut 442. Figure 7 As shown. A washer is provided between the two pin holes 430 to reduce the friction generated when the two scissor arms 450 rotate relative to each other.

[0078] It is understandable that the upper mounting base 310 and the lower mounting base 320 are each provided with a fixing base 800, such as Figure 8 and Figure 9 As shown, the fixed end 410 is rotatably connected to the fixed base 800 via a bearing and a shaft.

[0079] In some embodiments, the lower outer cover 220 is larger than the upper outer cover 210, and when the pedal body is in the retracted state, the upper outer cover 210 is embedded in the second mounting cavity 221. However, water droplets splashing from the bathroom can easily flow into the second mounting cavity 221 through the gap between the upper outer cover 210 and the lower outer cover 220 with the opening facing upward, causing water ingress and damage to the lifting mechanism and controller.

[0080] In this embodiment, the upper outer cover 210 is larger than the lower outer cover 220, such as... Figure 2As shown. When the pedal body is in the retracted state, the lower outer cover 220 is embedded in the first mounting cavity 211. Since the gap between the upper outer cover 210 and the lower outer cover 220 is set downward, splashing water droplets can be prevented from entering the toilet pedal 100, keeping the inside dry, preventing water from entering the geared motor 510 and the controller, and preventing the lead screw 520 from rusting.

[0081] Understandably, the upper surface of the outer cover 210 is provided with anti-slip parts, which are used to increase the friction between the user's shoe surface and the toilet pedal 100, and to prevent the user's feet from slipping.

[0082] Understandably, the lower end face of the lower cover 220 is also provided with anti-slip parts. The anti-slip parts are used to increase the friction between the lower cover 220 and the ground to prevent slipping.

[0083] It is understandable that the anti-slip parts are made of anti-slip materials such as rubber and silicone, and the two anti-slip parts are respectively attached to the upper outer cover 210 and the lower outer cover 220.

[0084] It is understandable that the rear end face of the toilet foot pedal 100 is a concave arc surface 230, such as... Figure 1 and Figure 2 As shown, the toilet foot pedal 100 is made more flush with the toilet, making it easier for the user to step on the toilet foot pedal 100 when using the toilet.

[0085] Understandably, the upper mounting base 310 and the lower mounting base 320 are respectively provided with reinforcing ribs 330 to increase strength and rigidity, and to reduce the degree of deformation of the upper mounting base 310 and the lower mounting base 320, such as Figure 8 As shown.

[0086] Understandably, since the drive assembly 500 is mounted on the lower mounting base 320, and the upper mounting base 310 has a notch 311, such as... Figure 5 and Figure 8 As shown, notch 311 is used to avoid one of the bearing seats 521 of the support screw 520.

[0087] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described.

All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
