Description

Technical Field

[0001] This invention relates to the field of washbasin technology, and in particular to a mobile washbasin capable of automatic docking and positioning. Background Technology

[0002] A washbasin is a device used for daily cleaning such as washing one's face and hands. Most washbasins are fixed, meaning they are stationary in a specific location for use. However, some are portable, designed to facilitate use by people with mobility impairments. These portable washbasins eliminate the need for people with mobility issues to walk to the washbasin location; instead, they can be moved to the side of the user without the user needing to move to the washbasin.

[0003] Existing portable washbasins require someone to move them to the user's side. When people with mobility impairments need to use them, someone else also needs to move the washbasin next to them, making it relatively inconvenient to use.

[0004] Meanwhile, once a portable washbasin is moved to a certain location, there is no good way to fix it in place. Collisions or even a light push can cause it to shift, making it unsuitable for temporary fixed use. Furthermore, the existing portable washbasins have fixed countertops, so when they are moved to the bedside, the user still needs to sit on the bedside to use them, which is also inconvenient. Summary of the Invention

[0005] To address the above shortcomings, this invention provides a mobile washbasin that can automatically dock and position itself, thus solving the problem that existing mobile washbasins require personnel to move them.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A mobile washbasin capable of automatic docking and positioning includes: The washbasin itself is equipped with a wash basin. A moving mechanism is used to support the washbasin body and move the washbasin body to a certain position; the moving mechanism is equipped with a controller to control the movement of the moving mechanism. A base station is fixed in a preset position. The base station is equipped with multiple infrared transmitters, each with a different code. Each infrared transmitter emits an infrared signal outward at a certain angle. An infrared receiver, mounted on the mobile mechanism, is used to receive infrared signals emitted by the infrared transmitter. The controller is electrically connected to the infrared receiver to control the mobile mechanism to move to or away from the base station based on the signal from the infrared receiver.

[0007] Furthermore, the base station has a positioning slot, the mobile mechanism is equipped with a positioning rod, and when the mobile mechanism moves to the side of the base station, the positioning rod can be inserted into the positioning slot.

[0008] Furthermore, a limiting hole is provided on the positioning rod, and an electromagnet is provided inside the limiting hole; The base station has a through hole at the position corresponding to the positioning groove, and a locking pin is installed in the through hole. The locking pin is made of ferromagnetic material so that when the positioning rod is inserted into the positioning groove and the electromagnet in the limiting hole is energized, the locking pin can be attracted to partially enter the limiting hole. The base station is equipped with a reset mechanism for disengaging the locking pin from the limiting hole.

[0009] Furthermore, there are two base stations, which are located in different locations.

[0010] Furthermore, the moving mechanism is provided with a rod driving mechanism for driving the positioning rod to extend or retract into the moving mechanism.

[0011] Furthermore, the washbasin body is mounted on the moving mechanism via a support member, the support member is rotatably connected to the moving mechanism, and the moving mechanism is provided with a rotation drive mechanism to drive the support member to rotate and drive the washbasin body to rotate.

[0012] Furthermore, the washbasin body is provided with a receiving groove, and the wash basin is housed in the receiving groove; The receiving slot is provided with a first lifting mechanism to lift or lower the washbasin. A fold is provided between the top outer edge of the washbasin and the receiving groove.

[0013] Furthermore, the washbasin body is provided with a cover plate, which can be rotated to cover the wash basin; The cover plate is equipped with an ultraviolet disinfection lamp.

[0014] Furthermore, the cover plate includes a fixed end, a first rotating part and a second rotating part. The fixed end is fixedly installed on the washbasin body. The first rotating part is rotatably installed on the fixed end so that it can be flipped on the vertical surface. The second rotating part is rotatably installed on the first rotating part so that it can be flipped on the vertical surface. When the first rotating part and the second rotating part are flipped to the horizontal state, they can cover the washbasin.

[0015] Furthermore, the second rotating part is provided with two contacts, which are disposed on the circuit of the ultraviolet disinfection lamp. The washbasin body is provided with a conductor, and when the cover plate covers the washbasin, the two contacts abut against the conductor to make the two contacts conductive.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention enables automatic docking and positioning of the mobile washbasin, eliminating the need for manual movement of the washbasin to the user, making it convenient to use and making the mobile washbasin more intelligent and automated; 2. It can temporarily fix the mobile washbasin, which can prevent the mobile washbasin from moving accidentally during use and ensure the reliability of use; 3. The washbasin body is rotatable and can be partially inserted above the hospital bed, making it convenient for users to use while sitting on the bed, without the need for users to sit on the edge of the bed, making it more convenient to use and more helpful for people with limited mobility. 4. The height-adjustable washbasin ensures that the solenoid valve at the bottom of the washbasin will not touch the patient or bedding when the washbasin body is rotated above the hospital bed, and can effectively prevent water from flowing down the receiving tank onto the hospital bed. 5. The washbasin can be disinfected by setting up an ultraviolet disinfection lamp, and the use of two contacts and a conductor ensures the safety of the ultraviolet disinfection lamp.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0023] Please refer to Figures 1 to 10A preferred embodiment of the present invention provides a mobile washbasin capable of automatic docking and positioning, which mainly includes a washbasin body 10, a wash basin 20, a moving mechanism 30, and a base station 40.

[0024] The washbasin body 10 is a single-unit structure. In this exemplary embodiment, the washbasin body 10 is a plate-like structure with a certain thickness to provide sufficient strength to support the washbasin 20 and other items on it. In this exemplary embodiment, the washbasin body 10 is a rectangular plate-like structure, one part of which is mainly used to place the washbasin 20, and the other part has a flat surface that can be used to place items such as a mouthwash cup or toothpaste. It is understood that the washbasin body 10 should not be too thick to avoid excessive volume or weight.

[0025] The moving mechanism 30 carries the washbasin body 10 and moves it to a certain position. The moving mechanism 30 includes a frame 33, Mecanum wheels 34, and a first motor 35 that drives the Mecanum wheels 34 to rotate. There are four Mecanum wheels 34, located at the four corners of the frame 33. Each Mecanum wheel 34 is equipped with a first motor 35. By setting the Mecanum wheels 34, the moving mechanism 30 can move omnidirectionally on the ground. The Mecanum wheels 34 are located at the bottom of the frame 33 so that they contact the ground, raising the frame 33 to a certain height, i.e., the bottom of the frame 33 is at a certain height above the ground, facilitating obstacle crossing, etc. The frame 33 has a plane in the middle, which can be used to support the washbasin body 10, etc., or to support other components, such as the clean water tank 36, the waste water tank 37, the storage battery, the controller (not shown in the figure), etc. The controller is a programmable logic controller, and the storage battery (not shown in the figure) is used to provide power to the electrical components on the moving mechanism 30.

[0026] The moving mechanism 30 is equipped with a controller to control the movement of the moving mechanism 30. The controller is electrically connected to the first motor 35 corresponding to each Mecanum wheel 34, so as to control the Mecanum wheel 34 by operating the first motor 35, thereby realizing the movement of the moving mechanism 30.

[0027] The base station 40 is fixed at a preset position, which is a temporary fixed position and also the position where the mobile mechanism 30 is designated to move. That is, by manipulating the mobile mechanism 30 to move next to the base station 40 at the preset position, the docking and positioning of the mobile washbasin can be achieved. The base station 40 is equipped with multiple infrared transmitters 51, each with different codes. Each infrared transmitter 51 emits infrared signals outward at a certain angle. In this exemplary embodiment, there are four infrared transmitters 51 arranged horizontally side by side.

[0028] An infrared receiver 52 is mounted on the mobile mechanism 30 to receive infrared signals emitted by the infrared transmitter 51. The infrared receiver 52 is electrically connected to the controller, which controls the mobile mechanism 30 to move near or away from the base station 40 based on the signal from the infrared receiver 52. The controller and the first motor 35 are electrically connected to a battery to supply power to the controller and the first motor 35. The infrared transmitters 51 have different codes, so after the infrared receiver 52 receives the infrared signal, it transmits it to the controller. The controller can determine which infrared transmitter 51 emitted the received infrared signal based on the code, thereby roughly determining the approximate position of the mobile mechanism 30.

[0029] In implementation, the following is an exemplary embodiment of the present invention: four infrared emitters 51 correspond to a transmission range (angle range), which sequentially corresponds to the position of the infrared emitters 51. For example, the transmission range of the leftmost infrared emitter 51 is located at the leftmost position. The transmission ranges of adjacent infrared emitters 51 may partially overlap to ensure continuous area coverage. When docking and positioning are required, the infrared receiver 52 receives the infrared signal and transmits the signal to the controller. The controller determines the approximate area of ​​the moving mechanism 30 based on the encoding of the signal. For example, if the moving mechanism 30 is facing the base station 40 (in this exemplary embodiment, the infrared receiver 52 is facing the center of the four infrared emitters 51), the controller controls the first motor 35 to rotate and manipulates the Mecanum wheel 34 to make the moving mechanism 30 walk directly towards the base station 40 in a straight line until the moving mechanism 30 moves next to the base station 40. At this time, docking and positioning are achieved. The washbasin body 10 and wash basin 20 on the moving mechanism 30 are also included. Once the mobile washbasin is moved to the corresponding position, it achieves its own mobile positioning. If the controller determines from the signal encoding that the approximate area of ​​the moving mechanism 30 is not directly facing the base station 40 (e.g., slightly to the left), the controller controls the first motor 35 to rotate and manipulates the Mecanum wheel 34 to make the moving mechanism 30 move laterally to the right (towards the center) until the moving mechanism 30 is directly facing the base station 40. Then, the controller controls the first motor 35 to rotate and manipulates the Mecanum wheel 34 to make the moving mechanism 30 move directly towards the base station 40 in a straight line until the moving mechanism 30 moves next to the base station 40, at which point docking and positioning are achieved. Through the above method, the mobile washbasin can achieve automatic docking and positioning, eliminating the need for manual movement of the washbasin to the user, making it convenient to use and making the mobile washbasin more intelligent and automated.

[0030] It is understood that the base station 40 can be installed in a specific location according to actual usage needs, such as under the hospital bed. When in use, the moving mechanism 30 can move the washbasin body 10 and its basin 20 to the bedside for the patient's use, without requiring the patient or others to move the mobile washbasin. After use, the moving mechanism 30 can be controlled by the controller to move away, such as moving the mobile washbasin to another location. It is understood that two base stations 40 can be set up, each in a different location, such as one under the hospital bed and the other against the wall of the ward. In this case, the moving mechanism 30 can move to different base stations; when in use, it moves to the base station 40 near the hospital bed, and after use, it moves to the base station 40 against the wall. It is understood that the mobile washbasin of this invention, capable of automatic docking and positioning, can be equipped with a remote control or controlled via voice interaction through a controller. The technology of using a remote control or controlling the controller via voice interaction is existing technology and will not be detailed here.

[0031] In a preferred embodiment, the base station 40 has an overall elongated rod-like structure, with infrared transmitters 51 arranged horizontally in the middle of the base station 40. The base station 40 has positioning slots 41, preferably two, located at both ends of the base station 40. The mobile mechanism 30 is equipped with two positioning rods 31, which are mounted on the frame 33. The frame 33 is equipped with a slide rail 314, and the positioning rods 31 are matched and installed on the slide rail 314. The distance between the two positioning rods 31 is equal to the distance between the two positioning slots 41. When the mobile mechanism 30 moves to the side of the base station 40 and achieves docking and positioning, the positioning rods 31 are inserted into the positioning slots 41 one by one. At this time, the positioning rods 31 can achieve multi-directional limitation through the insertion of the positioning rods 31 and the positioning slots 41. That is, except for moving away from the positioning slots 41 (set as backward), the positioning rods 31 cannot move forward, left, right, or up and down in the positioning slots 41. Thus, the positioning rods 31 can be limited and fixed in multiple directions, which also means that the mobile mechanism 30 can be limited and fixed in multiple directions. This enables the temporary fixation of the mobile washbasin after docking and positioning, preventing accidental movement.

[0032] A limiting hole 311 is provided on the positioning rod 31. An electromagnet is installed inside the limiting hole 311. A relay is configured on the control circuit of the electromagnet and is electrically connected to the controller. When the controller operates the relay, the circuit of the electromagnet is switched on and off. When the circuit is on, the electromagnet is energized and generates magnetism. When the circuit is off, the electromagnet loses its electromagnetic properties. The base station 40 has a through hole at the position corresponding to the positioning groove 41, which extends into the positioning groove 41. A locking pin 42 is installed in the through hole. The locking pin 42 is made of ferromagnetic material so that when the positioning rod 31 is inserted into the positioning groove 41 and the electromagnet in the limiting hole 311 is energized, the locking pin 42 can be attracted and partially enter the limiting hole 311. The base station 40 is provided with a reset mechanism for disengaging the locking pin 42 from the limiting hole 311. In this exemplary embodiment, the reset mechanism includes a sleeve 43 fixed to the top of the base station 40. The top of the sleeve 43 has a constricted structure. A compression spring 44 is provided inside the sleeve 43. The locking pin 42 passes through the sleeve 43 and has an annular boss in the middle. The boss is located inside the sleeve 43 and the outer circumference of the boss is larger than the inner diameter of the constricted top of the sleeve 43 so that the boss cannot go out from the top of the sleeve 43. The compression spring 44 is sleeved around the locking pin 42, with one end abutting against the top surface of the base station 40 and the other end abutting against the boss. Under the action of the compression spring 44, the bottom of the locking pin 42 does not extend into the positioning groove 41. When the positioning rod 31 is inserted into the positioning groove 41 and the electromagnet in the limiting hole 311 is energized by the controller, the electromagnet is energized and magnetically attracts the locking pin 42 to move towards the limiting hole 311. The locking pin 42 compresses the compression spring and enters the limiting hole 311. At this time, a limit is achieved through the interaction between the limiting hole 311 and the locking pin 42. At this time, the positioning rod 31 cannot leave the positioning groove 41, and the moving mechanism 30 is temporarily fixed, thus temporarily fixing the mobile washbasin in the position after docking and positioning, preventing it from moving accidentally due to collision or pushing. When the moving mechanism 30 needs to move, the electromagnet in the limiting hole 311 is de-energized by the controller. Under the action of the compression spring 44, the locking pin 42 moves upward and leaves the limiting hole 311 and the positioning groove 41. At this time, the positioning rod 31 can leave the positioning groove 41, the limit on the positioning rod 31 is released, and the moving mechanism 30 can move.

[0033] The moving mechanism 30 is equipped with a rod driving mechanism 32 for driving the positioning rod 31 to extend or retract. In this exemplary embodiment, when the moving mechanism 30 moves, the positioning rod 31 is retracted at the bottom of the moving mechanism 30, specifically at the bottom of the frame 33. When the positioning rod 31 needs to be inserted into the positioning slot 41, the rod driving mechanism 32 drives the positioning rod 31 to extend and enter the positioning slot 41. When the positioning rod 31 needs to leave the positioning slot 41, the rod driving mechanism 32 drives the positioning rod 31 to retract and leave the positioning slot 41. By using the rod driving mechanism 32 to drive the positioning rod 31 to extend or retract, the positioning rod 31 can be retracted, preventing it from continuously extending and affecting the movement of the moving mechanism 30 or scratching objects. In the exemplary embodiment, the rod driving mechanism 32 is an electric actuator, and the rod driving mechanism 32 of the electric actuator is electrically connected to the controller for operation. A crossbar is provided on the telescopic shaft of the insertion rod drive mechanism 32 for the electric actuator, and two positioning insertion rods 31 are respectively provided at both ends of the crossbar.

[0034] The portable washbasin of this invention can automatically dock and position itself, and temporarily fix itself after positioning to prevent accidental movement during use. The frame 33 has a clearance groove in the middle of the side closest to the base station 40 during positioning, and flat surfaces on the top surfaces of both ends. On one hand, the two positioning rods 31 can retract below this position. On the other hand, by setting this flat surface, when the mobile mechanism 30 of the portable washbasin moves to the bedside, the user can sit on the bed with their feet resting on the two flat surfaces. This solves the problem of existing portable washbasins having nowhere to rest the feet when moved to the bedside. Furthermore, due to the fixing method of the positioning rods 31 and the positioning groove 41, the mobile mechanism 30 will not move accidentally when the feet are placed on it, ensuring reliable use.

[0035] In a preferred embodiment, the washbasin body 10 is mounted on the moving mechanism 30 via a support member 11. The support member 11 is rotatably connected to the moving mechanism 30, and the moving mechanism 30 is provided with a rotation drive mechanism to drive the support member 11 to rotate and thus rotate the washbasin body 10. In this exemplary embodiment, the washbasin body 10 is a rectangular plate structure. One end of the washbasin body 10 is fixedly connected to the support member 11. The support member 11 is rotatably connected to the frame 33 of the moving mechanism 30 via a bearing seat with ball bearings 111. Therefore, the rotation of the support member 11 can drive the washbasin body 10 to rotate, thereby changing the position of the washbasin body 10. For example, when the user is sitting on the edge of the bed, the position of the washbasin body 10 corresponds to the placement of the hospital bed. Figure 1As shown, this design allows the user to use the washbasin while seated on the edge of the bed; when the washbasin body 10 is rotated 90°, its position is perpendicular to the bed's placement, and it partially extends above the bed. Figure 3 As shown, it is convenient for users to use while sitting on the hospital bed. By rotating the washbasin body 10, the position of the washbasin body 10 relative to the hospital bed can be changed. For example, if it is partially located above the hospital bed, the user only needs to sit up and does not need to sit on the edge of the bed, making it more convenient to use and more helpful for people with mobility impairments.

[0036] In a preferred embodiment, the rotation drive mechanism includes a second motor 38 and a gear pair 39. The second motor 38 is fixedly mounted on the frame 33 of the moving mechanism 30. The gear pair 39 includes two bevel gears, one of which is fixedly connected to the output shaft of the second motor 38, and the other is fixedly connected to the support member 11. The two bevel gears mesh with each other. When the second motor 38 starts, it drives the bevel gear on it to rotate, and the other bevel gear rotates accordingly, thereby driving the support member 11 to rotate. The rotation of the support member 11, in turn, drives the washbasin body 10 to rotate. In a preferred embodiment, a protective cover 310 is provided on the frame 33. The protective cover 310 covers the gear pair 39 to prevent the gear pair 39 from being exposed and to prevent the gears from rotating and entangled in items during use. The support member 11 can preferably be an electric actuator, thereby enabling the washbasin body 10 to be raised and lowered. The second motor 38 and the support member 11 (which is an electric actuator) are electrically connected to the controller and controlled by the controller.

[0037] The washbasin body 10 has a receiving groove 12, in which the washbasin 20 is housed. A solenoid valve 313 is installed at the bottom of the washbasin 20. The solenoid valve 313 is connected to a wastewater tank 37 via a flexible hose (not shown in the figure), allowing wastewater to be discharged into the wastewater tank 37. The solenoid valve 313 is electrically connected to a controller and is controlled by the controller. Similar to a conventional washbasin 20, when the water level in the washbasin 20 exceeds a certain amount, it can automatically be flushed into the wastewater tank 37 through a pipe. A faucet 312 is installed next to the receiving groove 12. The faucet 312's water outlet is located above the washbasin 20. The faucet 312 uses a sensor-based water dispensing method and is equipped with a miniature water pump (not shown in the figure). The miniature water pump is connected to a purified water tank 36 via a flexible hose (not shown in the figure), allowing purified water to be delivered to the faucet 312 and then to the washbasin 20. The infrared sensor of the faucet 312 is electrically connected to the controller and transmits the detection signal to the controller. The micro water pump is electrically connected to the controller and is controlled by the controller. When the infrared sensor of the faucet 312 detects an obstruction such as a human hand entering the detection range, it sends a signal to the controller. The controller controls the micro water pump to draw water from the water purification tank 36 and deliver it to the washbasin 20 through the faucet 312.

[0038] A first lifting mechanism 13 is provided in the receiving tank 12 to lift or lower the washbasin 20, that is, the washbasin 20 can be raised and lowered within the receiving tank 12. The first lifting mechanism 13 is preferably an electric actuator, and the first lifting mechanism 13 with the electric actuator is electrically connected to the controller and controlled by the controller.

[0039] A folding part 21 is provided between the top outer edge of the washbasin 20 and the receiving groove 12. The folding part 21 is arranged around the inner circle of the receiving groove 12. The folding part 21 is made of a flexible material such as rubber or plastic and has multiple folds around the circumference so that it can be stretched when the washbasin 20 is lifted and compressed when the washbasin 20 is lowered.

[0040] The existing portable washbasins are only used by the bedside, meaning the user sits on the bedside and the position of the washbasin 20 is not critical. The portable washbasin of the present invention allows users to use it while sitting on the bed by rotating the washbasin body 10. Since the washbasin 20 has a certain height and is equipped with components such as a solenoid valve 313 at the bottom, and the washbasin body 10 should not be set too high to be inconvenient to use, when the washbasin body 10 is rotated above the hospital bed, the solenoid valve 313 and other components at the bottom of the washbasin 20 may hit the patient or bedding, which is not conducive to use. Therefore, the present invention provides a first lifting mechanism 13. Before the washbasin body 10 needs to be rotated above the hospital bed, the first lifting mechanism 13 lifts the washbasin 20. At this time, the solenoid valve 313 and other components at the bottom of the washbasin 20 rise together and enter the receiving groove 12 completely. Only the sewage hose comes out. Thus, when the washbasin body 10 is rotated above the hospital bed, it is ensured that the solenoid valve 313 and other components at the bottom of the washbasin 20 will not hit the patient or bedding. Meanwhile, due to the folding part 21, the receiving groove 12 is isolated from the top of the washbasin body 10, thereby ensuring that the washbasin 20 is in the raised state (e.g. Figure 7 and Figure 8 As shown), water will not flow down into the bed through the container 12 during handwashing or other situations.

[0041] In a preferred embodiment, the washbasin body 10 is provided with a cover 14, which can be rotated to cover the washbasin 20. An ultraviolet disinfection lamp 15 is provided on the cover 14, and a battery is electrically connected to the ultraviolet disinfection lamp 15 to provide power to it. After use, the user can rotate the cover 14 to cover the washbasin 20 and turn on the ultraviolet disinfection lamp 15 via a switch, thereby achieving ultraviolet disinfection of the washbasin 20.

[0042] The cover plate 14 includes a fixed end 141, a first rotating part 142, and a second rotating part 143. Both the first rotating part 142 and the second rotating part 143 are flat plate structures. The fixed end 141 is fixedly installed on the washbasin body 10. The first rotating part 142 is rotatably installed on the fixed end 141 so that it can be flipped on the vertical surface. The second rotating part 143 is rotatably installed on the first rotating part 142 so that it can be flipped on the vertical surface. When the first rotating part 142 and the second rotating part 143 are flipped to the horizontal state, they can cover the washbasin 20. Through the multi-segment rotating parts, such as the first rotating part 142 and the second rotating part 143, multiple folds can be made so that when it is covered on the washbasin 20 or flipped up, it avoids the faucet 312, avoids interference with the faucet 312, and avoids inconvenience in flipping up or covering it. The second rotating part 143 is provided with two contacts 144, which are connected to the circuit of the ultraviolet disinfection lamp 15. The washbasin body 10 is provided with a conductor 16. When the cover 14 covers the washbasin 20, the two contacts 144 abut against the conductor 16 to make the two contacts 144 conductive, thus enabling the circuit of the ultraviolet disinfection lamp 15 to conduct. The ultraviolet light generated by the ultraviolet disinfection lamp 15 has a disinfecting effect; however, direct irradiation of the human body can also cause harm, such as skin damage and eye damage. Since the ultraviolet light generated by the ultraviolet disinfection lamp 15 is invisible to the human eye, if the ultraviolet disinfection lamp 15 is turned on before the cover 14 covers the washbasin 20, the ultraviolet light may directly irradiate the human body. By setting two contacts 144, in conjunction with the conductor 16, the two contacts 144 can only conduct electricity when they abut against the conductor 16 and the cover 14 is covering the washbasin 20. Only then can the circuit of the ultraviolet disinfection lamp 15 be turned on, and disinfection can be achieved by turning on the ultraviolet disinfection lamp 15. This method ensures the safe use of the ultraviolet disinfection lamp 15.
