Description

Technical Field

[0001] The utility model relates to a technical improvement of a toilet structure, in particular to a new electric toilet. Background Art

[0002] The new electric toilet is an indispensable piece of furniture for every family. With the rapid development of smart home, the promotion of the new electric toilet has penetrated into every household. It not only has a fully automatic flushing function, but also has a heated seat function, allowing consumers to experience more technology.

[0003] Patent announcement number CN215127935U discloses an electric toilet cover, which has the following technical advantages: the toilet cover can close the toilet seat opening by electric flipping. Generally, when the motor is intact and fault-free, there is no need to manually flip the toilet cover when the power is turned on, so as to prevent human hands from contacting urine, sputum or other excrement, dirt, etc. that may be attached to the toilet cover; according to the design technical scheme of the electric toilet cover, when the motor of the toilet cover accidentally loses power or an electromechanical failure occurs (the motor cannot provide electric power), the toilet user can manually flip the toilet cover at will. In the process of manually flipping the toilet cover, there is no need to forcefully overcome the mechanical resistance of the motor caused by power failure or failure, and the toilet cover can be easily and freely driven to flip into place (tilt upright and lean against the toilet tank or horizontally cover the toilet opening). In this way, not only can the toilet cover be prevented from possible deformation or even rupture, but also the motor or other components can be effectively prevented from failure or damage, and the toilet cover can be kept working in a normal and lossless flipping manner in the event of an accidental power failure or electromechanical failure of the motor.

[0004] However, according to the literature, the design structure of the above-mentioned patented toilet seat product is relatively complex, and its application in existing toilets will undoubtedly significantly increase the production, assembly and sales costs, which is not conducive to popularization in the market. Others;

[0005] Therefore, based on the existing technology, improving and designing a new electric toilet with a simpler structure, low cost of use and manual opening of the lid does not affect the working performance of the toilet lid is a technical problem that needs to be urgently solved in the utility model application. Utility Model Content

[0006] The purpose of the utility model is to provide a new type of electric toilet, which not only has an automatic flip-up function, but also can be flipped manually, and the manual flipping will not cause structural or performance effects on components such as the toilet cover or the motor, thereby solving the problems raised in the above-mentioned background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A new electric toilet comprises a toilet body, wherein the toilet body comprises an upper cover and a base, wherein the upper cover is flipped on the base via a connecting mechanism, wherein the connecting mechanism comprises a driving unit and a transmission unit, wherein the driving unit comprises a driver and a driving rod connected to its transmission shaft, wherein the driving rod is coaxially arranged opposite to a rotating rod of the upper cover and is provided with a limiting ring, wherein a pushing mechanism is provided on the limiting ring; wherein the transmission unit comprises a limiting gear, wherein the limiting gear is fixedly connected to the rotating rod of the upper cover and can rotate synchronously; wherein the pushing mechanism can contact the limiting gear in a power-on state and drive the limiting gear to rotate under the action of the driver, and can be separated from the limiting gear in a power-off state.

[0009] As a preferred solution of the present application: the pushing mechanism includes a fixed frame fixedly connected to the outer wall of the limit ring, and the interior of the fixed frame is provided with a clamping rod, a static magnet and a moving magnet corresponding to the static magnet, the static magnet is arranged below the moving magnet, and the top of the clamping rod passes through the static magnet and is connected to the moving magnet. When power is turned on, the static magnet can generate magnetism to attract the moving magnet, and then drive the clamping rod to extend and clamp with the limit gear through the magnetic attraction force.

[0010] As a preferred solution of the present application: the static magnet is an attraction type electromagnet.

[0011] As a preferred solution of the present application: the top of the clamping rod is fixedly connected to the moving magnet, and when the moving magnet is attracted by magnetic force, it will drive the clamping rod to move synchronously. When the clamping rod extends downward into the tooth groove of the limiting gear, the limiting ring and the limiting gear will be in a restricted state, and the limiting gear can be driven to move synchronously as the limiting ring rotates.

[0012] As a preferred solution of the present application: the teeth of the limit gear are designed in the shape of a right-angled trapezoid and correspond to the clamping rod.

[0013] As a preferred solution of the present application: a return spring is arranged between the upper part of the moving magnet and the inside of the fixed frame.

[0014] As a preferred solution of the present application: the connecting mechanism also includes support frames fixedly installed on both sides of the base, the rotating rod is rotatably connected between the two support frames, the rotating rod is fixedly connected to the limit gear, and the limit gear rotates on the support frame through the rotating rod.

[0015] As a preferred solution of the present application: the driver and the pushing mechanism are respectively connected to the same controller, and the controller can control the driver and the pushing mechanism to be powered on or off.

[0016] Compared with the prior art, the beneficial technical effects of the utility model are:

[0017] The push mechanism is a connecting device between the driver and the upper cover. When powered on, the static magnet has magnetic force that attracts the moving magnet to move downward, driving the clamping rod to move downward close to the limit gear, and during the rotation of the limit ring, the limit gear can also be driven to rotate through the clamping rod, thereby driving the upper cover to flip. After the flip is completed, under the action of the delay device, the controller will control the push mechanism and the driver to cut off the power. After the static magnet loses the current, it loses the magnetic force. At this time, under the action of the reset spring, the moving magnet moves upward, driving the clamping rod away from the limit gear. At this time, the limit gear loses the limiting force and is in a free state. The user can flip the upper cover (toilet cover) up and down at will, thereby achieving the technical effect of flipping the upper cover without overcoming the mechanical resistance of the driver, that is, the motor due to power failure or failure, solving the problem that the existing new electric toilet needs to overcome the mechanical resistance of the motor due to power failure or failure when manually flipping the cover, which is easy to deform the toilet cover, and even cause the motor or other components to fail, improving the experience of the existing electric toilet when using it and the life of the electric toilet, and also protecting the toilet cover.

[0026] The present invention will be further described in detail below in conjunction with specific implementations and with reference to the accompanying drawings. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope of the present invention and its application.

[0027] like Figure 1 As shown, a new type of electric toilet provided in this embodiment includes a toilet body 10, and the toilet body 10 includes an upper cover 20 and a base 30. In daily use, the base 30 of the new electric toilet has the functions of heating and automatic flushing. In the process of consumers using the new electric toilet, because a heater is provided on the base 30 to heat the seat cushion, the human body will not be stimulated by cold in winter due to the material of the toilet. At the same time, a sensor is provided on the base, and flushing will be performed during the process of human body contact or distance; thereby achieving the self-cleaning effect of the toilet. In addition, due to the current development of urbanization, many families have small households, and the toilet is close to the living room or kitchen. After using the toilet, it is necessary to close the toilet door in time and open the window for ventilation. At this time, the upper cover 20 also needs to be closed to avoid the odor of the sewer. Therefore, in the prior art, an automatically closed upper cover 20 is provided. After the user leaves the toilet, the upper cover 20 is automatically closed for a period of time by a motor drive, thereby reducing the odor in the toilet.

[0028] On the basis of the prior art, if there is a power outage or motor failure, the upper cover 20 of the new electric toilet cannot be opened and closed automatically. At this time, it is necessary to manually operate the upper cover 20, because the opening and closing of the toilet upper cover 20 in the prior art is generally driven directly by a motor, and manual operation must inevitably overcome the mechanical resistance of the motor due to power failure or failure. However, most toilet covers are made of plastic. While overcoming the mechanical resistance of the motor due to power failure or failure, an external force will be applied to the toilet cover, which may cause deformation or damage (cracks) of the toilet cover. Moreover, when the motor used in the new electric toilet is a stepper motor, the toilet cover cannot be opened manually. If it is forced to open, it may not only damage the mechanical structure of the toilet cover, but may also cause failure of the stepper motor or other components, making the toilet unable to work normally. Therefore, in order to solve this problem, the following improvements are made.

[0029] like Figure 2As shown, the toilet body 10 includes an upper cover 20 and a base 30. The upper cover 20 is flipped on the base 30 through a connecting mechanism 40. The connecting mechanism 40 includes a driving unit 43 and a transmission unit. The driving unit 43 includes a driver and a driving rod 44 connected to its transmission shaft. It can be understood that the driver can be an existing small motor. In this embodiment, the driver is preferably installed on the base 30. The driving rod 44 is coaxially arranged relative to the rotating rod 42 of the upper cover 20 and is provided with a limiting ring 441. At the same time, a pushing mechanism 50 is provided on the limiting ring 441. It can be understood that there should be at least a millimeter-level gap between the rotating rod 42 and the driving rod 44 to avoid mutual interference. The transmission unit includes a limiting gear 421, which is fixedly connected to the rotating rod 42 of the upper cover 20 and can rotate synchronously. The pushing mechanism 50 can contact the limiting gear 421 when powered on and drive the limiting gear 421 to rotate under the action of the driver, and can be separated from the limiting gear 421 when powered off.

[0030] It can be understood that in this embodiment, in order to simplify the control program, the driver and the pushing mechanism 50 are respectively connected to the same controller, which can be an existing common single-chip microcomputer or PLC. The controller can control the driver and the pushing mechanism 50 to be powered on or off in sequence according to user needs. The interaction between user needs and the controller can be achieved through the existing corresponding sensor devices. This is an existing conventional means and will not be elaborated in this embodiment.

[0031] During specific use, after power is turned on, the pushing mechanism 50 first contacts the limit gear 421. When the driver, that is, the motor, is powered on to drive the driving rod 44 connected to the transmission shaft to rotate, the driving rod 44 will drive the limit ring 441 to rotate synchronously. Since the pushing mechanism 50 is set on the limit ring 441, the motor will drive the pushing mechanism 50 to rotate through the driving rod 44 and the limit ring 441, and then drive the upper cover to open and close through the pushing mechanism 50 and the limit gear 421; after power is lost, the pushing mechanism 50 will be disengaged from the limit gear 421, that is, when the power is off, the pushing mechanism 50 will be in a power-off state. At this time, the pushing mechanism 50 is separated from the limit gear 421, and then the driving rod 44 connected to the motor end is separated from the rotating rod 42. At this time, when manually opening and closing the upper cover 20, there is no need to overcome the mechanical resistance of the motor due to power failure or failure, which will not affect the structure of the toilet cover, and will not cause damage to the motor and other mechanisms.

[0032] In this embodiment, a groove is opened inside the limiting ring 441, and the limiting gear 421 is placed in the groove and can rotate relative to the limiting ring 441. It can be understood that the design of the groove can reduce the distance between the limiting gear 421 and the limiting ring 441, so that the size of the connecting mechanism 40 is more compact, which is convenient for installation and improves the aesthetics.

[0033] It can be seen that the new electric toilet in this embodiment has a simple structure and low cost. At the same time, when it is manually turned over, there is no need to overcome the mechanical resistance caused by power failure or failure of the motor. It can increase the service life of the toilet and reduce the cost of using the toilet. It has certain market value and potential economic benefits.

[0034] like Figures 3 to 6 As shown, the pushing mechanism 50 includes a fixed frame 51 fixedly connected to the outer wall of the limiting ring 441, and the interior of the fixed frame 51 is provided with a clamping rod 442, a static magnet 52 and a moving magnet 53 corresponding to the static magnet 52. The static magnet 52 is arranged below the moving magnet 53, and the top of the clamping rod 442 passes through the static magnet 52 and is connected to the moving magnet 53. When power is turned on, the static magnet 52 can generate magnetism to attract the moving magnet 53, and then drive the clamping rod 442 to extend and clamp with the limiting gear 421 through the magnetic attraction force. It can be understood that the static magnet 52 should be an attractive electromagnet. In this embodiment, when power is turned on, the static magnet 52 has magnetic force and can attract the moving magnet 53, thereby driving the moving magnet 53 to move downward inside the fixed frame 51. Since the top of the clamping rod 442 passes through the static magnet 52 and is fixedly connected to the moving magnet 53, when the moving magnet 53 moves, it will drive the clamping rod 442 to move downward synchronously and contact (clamp) with the limit gear 421. During the rotation of the limit ring 441, the limit gear 421 will be driven to rotate through the clamping rod 442, thereby driving the upper cover 20 to flip open and close.

[0035] When the flipping is completed, under the action of the timer, the controller controls the pushing mechanism 50 to cut off the power, and the static magnet 52 loses the current and the magnetic force. At this time, the moving magnet 53 moves upward, driving the clamping rod 442 to separate from the limit gear 421, so that the limit gear 421 loses the limiting force and is in a free state. At this time, the limit gear 421 is not restricted by the pushing mechanism 50 when rotating in the groove of the limit ring 441, and the user can flip the upper cover 20 up and down at will. The advantages of this are, first, after a power outage or a motor failure, it will not affect the normal use of the toilet, and second, there is no need to overcome the resistance of the motor when flipping the upper cover 20.

[0036] In order to quickly reset the moving magnet 53 , a reset spring 54 is provided between the upper side of the moving magnet 53 and the inside of the fixed frame 51 in this embodiment. After power failure, the moving magnet 53 automatically moves upward and resets under the action of the reset spring 54 .

[0037] The top of the clamping rod 442 is fixedly connected to the moving magnet 53. When the moving magnet 53 is attracted by magnetic force, the clamping rod 442 will be driven to move synchronously. When the clamping rod 442 extends downward to the tooth groove of the limiting gear 421, the limiting ring 441 and the limiting gear 421 will be in a restricted state. As the limiting ring 441 rotates, the limiting gear 421 can be driven to move synchronously. It can be understood that in order to achieve accurate and tight clamping between the clamping rod 442 and the teeth on the limiting gear 421, the teeth on the limiting gear 421 should be respectively provided with a wedge surface structure that can facilitate alignment with the end of the clamping rod 442. In this embodiment, the teeth on the limiting gear 421 and the end of the clamping rod are preferably in the shape of a right-angled trapezoid.

[0038] When the upper cover 20 needs to be opened, it can be manually flipped open, or a timer can be built into the controller to automatically power on and open after the upper cover 20 is closed for a certain period of time to ensure that the odor is reduced. The user can also start the controller to drive the pushing mechanism 50 and the driver to power on in sequence through the controller. After the pushing mechanism 50 is powered on, it is ensured that the engaging rod 442 is engaged with the teeth on the limit gear 421. After the driver is powered on, the driving rod 44, the limit ring 441 and the pushing mechanism 50 are driven to rotate in the opposite direction, and then the limiting gear 421 is driven to rotate through the engaging rod 442 on the pushing mechanism 50, thereby opening the upper cover 20.

[0039] The connection mechanism 40 also includes support frames 41 fixedly mounted on both sides of the base 30, a rotating rod 42 rotatably connected between the two support frames 41, and the rotating rod 42 is fixedly connected to the limit gear 421, and the limit gear 421 rotates on the support frame 41 through the rotating rod 42. In this embodiment, after the limit gear 421 is limited by extending the clamping rod 442 downward, the driver cooperates with the transmission shaft to drive the driving rod 44 to rotate, and the driving rod 44 drives the limit ring 441 fixedly connected thereto to rotate, and cooperates with the clamping rod 442 to drive the limit gear 421 to rotate. In this process, the limit gear 421 drives the rotating rod 42 fixedly connected thereto to rotate between the two support frames 41 to achieve control of the upper cover 20. The rotating rod 42 and the driving rod 44 are both on the same axis.

[0040] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
