Description

Technical Field

[0001] This utility model relates to the technical field of bathroom equipment, and in particular to a locking structure for a toilet seat and a self-cleaning toilet. Background Technology

[0002] As an indispensable sanitary facility in daily life, especially in public places, the toilet seat, due to its high frequency of use and multiple users, is an ideal carrier for pathogenic microorganisms such as bacteria and viruses, significantly increasing the risk of cross-infection.

[0003] Existing technologies have developed the use of high-temperature steam for physical cleaning and sterilization of toilet seats. To ensure the safety and effectiveness of the high-temperature steam cleaning process, avoid accidental leakage of high-temperature steam or burns caused by users accidentally touching high-temperature parts, and ensure that the steam can fully function in a closed space to improve sterilization efficiency, existing technologies generally require that the toilet seat and toilet seat be reliably locked during steam cleaning operations.

[0004] Existing technologies generally employ manual mechanical latches or electromagnetic adsorption, the basic principle of which is to fix the toilet seat and seat ring in a specific position through the physical overlap or magnetic attraction of components. However, these solutions have obvious shortcomings: traditional mechanical locking solutions require the design of relatively complex linkage structures, which not only increases manufacturing costs and installation difficulty, but also introduces more points of failure; while the locking force provided by electromagnetic adsorption may be insufficient when dealing with vibrations generated during high-intensity cleaning or accidental external impacts, and there is a risk of accidental release.

[0005] Therefore, how to provide a locking structure that is both stable and reliable and can be automated has become a technical problem that urgently needs to be solved. Summary of the Invention

[0006] This invention overcomes the shortcomings of the prior art and provides a locking structure for a toilet seat and a toilet bowl.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a locking structure for a toilet seat and a seat ring and a self-cleaning toilet, comprising: a mounting frame, two connecting blocks disposed on one side of the toilet seat, and a locking component disposed within the mounting frame;

[0008] The locking assembly includes: an electric push rod, a pin disposed at one end of the output rod of the electric push rod, a connecting rod disposed between the electric push rod and the pin, and two transmission rods symmetrically disposed within the mounting frame;

[0009] The two symmetrical transmission rods are respectively fixedly connected to the two connecting blocks, and the bottom of the mounting frame is fixedly connected to two locking screws.

[0010] In a preferred embodiment of this utility model, the electric push rod is fixedly connected to the bottom inner wall of the mounting frame.

[0011] In a preferred embodiment of this utility model, the electric push rod and the pin are movably connected by a connecting rod.

[0012] In a preferred embodiment of this utility model, the two symmetrical transmission rods are rotatably connected to the mounting frame.

[0013] In a preferred embodiment of the present invention, a sliding groove is provided on one side of one of the transmission rods, and one end of the pin is located in the sliding groove and slidably connected.

[0014] In a preferred embodiment of this utility model, a limiting groove is provided on one side of the pin, and a limiting vertical rod is fixedly connected between the inner circumferential walls of the sliding groove.

[0015] In a preferred embodiment of this utility model, the limiting groove is engaged with the limiting vertical rod.

[0016] In a preferred embodiment of this utility model, the limiting groove of the pin slides along the path of the limiting vertical rod.

[0017] In a preferred embodiment of this utility model, the mounting frame is fixedly connected to one side of the seat ring.

[0018] A self-cleaning toilet, comprising: a self-cleaning toilet.

[0019] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0020] (1) This utility model provides a locking structure for a toilet seat and a self-cleaning toilet. By using an electric push rod as the driving core, the electric push rod output rod pushes the connecting rod and the pin to achieve automatic locking and unlocking. This allows users to lock the toilet with one button without manual operation, improving the convenience and automation of use. Compared with the cumbersome manual mechanical latch or the easily malfunctioning electromagnetic adsorption method in the prior art, this design avoids users from directly contacting potentially contaminated parts and reduces the risk of cross-infection.

[0021] (2) This utility model provides a locking structure for a toilet seat and a self-cleaning toilet. By providing a limiting groove at one end of the pin, which engages with the limiting vertical rod in the sliding groove, the pin is ensured to slide along a predetermined path under the drive of the electric push rod without deviating or coming off. The direct effect is that the locking process is stable and reliable, and it can remain firmly locked even under vibration or external impact during the cleaning process, preventing accidental release. Compared with the simple electromagnetic adsorption or basic mechanical solutions of the prior art, this mechanical pin locking mechanism is more impact-resistant and wear-resistant, solving the problem of insufficient locking force in traditional methods. Furthermore, in a high-temperature steam cleaning environment, this locking structure can effectively ensure that the seat is tightly closed, avoiding steam leakage or accidental contact by the user, enhancing safety and cleaning efficiency.

[0022] (3) This utility model provides a locking structure for a toilet seat and a self-cleaning toilet. It uses two symmetrical transmission rods to be fixedly connected to the connecting block of the toilet seat, and the force is transmitted through the rotational connection with the mounting frame. This feature makes the locking force evenly distributed, improves the durability and reliability of the structure, reduces single-point failures, and avoids complex linkage structures or high-cost designs.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0029] like Figure 1 As shown, a locking structure for a toilet seat and a seat ring includes: a mounting frame, two connecting blocks 2 disposed on one side of the toilet seat, and a locking component disposed within the mounting frame;

[0030] The mounting frame is fixedly installed on the side edge of the seat ring 3, in the reserved installation area at the rear of the seat ring 3. Two connecting blocks 4 are symmetrically fixed on the corresponding sides of the toilet seat 2, their specific positions corresponding to the geometric center line of the mounting frame.

[0031] like Figure 1-3 As shown, the locking assembly includes: an electric push rod 5, a pin 6 located at one end of the output shaft of the electric push rod 5, a connecting rod 8 located between the electric push rod 5 and the pin 6, and two symmetrical transmission rods 4 located within the mounting frame; the electric push rod 5 is fixedly connected to the bottom inner wall of the mounting frame, and the electric push rod 5 and the pin 6 are movably connected through the connecting rod 8; the two symmetrical transmission rods 4 are rotatably connected to the mounting frame; one side of one transmission rod 4 has a sliding groove 10, one end of the pin 6 is located in the sliding groove 10 and is slidably connected; one side of the pin 6 has a limiting groove 9, and a limiting vertical rod 11 is fixedly connected between the inner circumference of the sliding groove 10; the limiting groove 9 engages with the limiting vertical rod 11; the limiting groove 9 of the pin 6 slides along the path of the limiting vertical rod 11; the mounting frame is fixedly connected to one side of the seat ring.

[0032] Two symmetrical transmission rods 4 are fixedly connected to two connecting blocks 2 respectively, and two locking screws 7 are fixedly connected to the bottom of the mounting frame.

[0033] It should be noted that the mounting frame, as the core load-bearing structure of the device body, provides a solid and stable foundation for the locking assembly through its fixed connection with the seat ring 3.

[0034] Specifically, the electric actuator 5 serves as the drive source, and its fixed installation on the inner wall of the bottom of the mounting frame optimizes the spatial layout and center of gravity distribution. The electric actuator 5 is a miniature DC linear electric actuator with a rated operating voltage of 24V DC to meet the system's requirements for power stability and power. Its maximum rated thrust reaches 300N, satisfying the mechanical load of the toilet seat and seat ring in the locked state, as well as the reaction force that may be generated during cleaning. The actuator's maximum stroke is 25mm, and its linear motion speed is 10mm / s, ensuring rapid response and smooth transition during locking and unlocking actions.

[0035] By driving the pin 6 through the movable connection with the connecting rod 8, the conversion from the linear motion of the electric push rod 5 to the complex motion of the pin 6 is realized. This power transmission method not only runs smoothly and has low noise, but also greatly improves the degree of automation of use. Users can complete locking and unlocking without manual intervention.

[0036] Two locking screws 7 penetrate directly through the bottom of the mounting frame, firmly securing it to the pre-installed mounting point on the toilet body. This direct mechanical connection creates an extremely stable installation foundation. The two locking screws 7 ensure that the entire mounting frame will not loosen or shift when the electric push rod 5 is repeatedly operated and the transmission rod 4 is rotated, providing a reliable premise for the locking action of the device body.

[0037] When the toilet seat 1 is frequently opened and closed or the self-cleaning system generates working vibrations, the locking screw 7 can effectively suppress structural resonance and prevent the screw from loosening or the mounting frame from shifting due to long-term minor vibrations, thereby ensuring the long-term stability and reliability of the locking function.

[0038] Furthermore, the engagement mechanism between the pin 6 and the transmission rod 4 is key to achieving reliable locking. The limiting groove 9 at one end of the pin 6 engages with the limiting vertical rod 11 fixed in the sliding groove 10, strictly constraining the movement trajectory of the pin 6, ensuring that it can only slide along the path specified by the limiting vertical rod 11, thus completely avoiding the risk of deviation, jamming, or accidental disengagement during operation.

[0039] This mechanical interlocking method gives the locking action extremely high reliability and durability. Even when the toilet self-cleaning program generates continuous vibration, it can always maintain a firm locking state, effectively preventing the seat ring 3 from opening accidentally and ensuring the safety and airtightness of the cleaning process.

[0040] Finally, the two symmetrically arranged transmission rods 4 are fixedly connected to the two connecting blocks 2 on the toilet seat 1, which produces the beneficial effect of uniform force distribution; it evenly distributes the locking force transmitted by the pin 6 to both sides of the toilet seat 1, significantly improving the durability and fatigue resistance of the structure under repeated operation.

[0041] In one specific embodiment, a control unit is also included, which is an ARM Cortex-M4 series microcontroller (STM32F407VG) used to control the drive of the electric actuator 5.

[0042] A self-cleaning toilet includes: a self-cleaning toilet, which further includes: an integrated instant steam generator with a rated power of 2.5kW, capable of heating room temperature water to 120℃ and generating 0.2MPa high-pressure saturated steam within 3 seconds; a series of high-temperature and corrosion-resistant ceramic steam nozzles, a total of 6, evenly distributed at preset positions on the lower surface of the seat ring, with optimized spray angles, used to spray the high-temperature steam onto the surface of the seat ring for cleaning and sterilization, and each nozzle having a steam flow rate of 1.5g / s.

[0043] When this utility model is in use, upon receiving a locking command, the output rod of the electric push rod 5 begins a linear extension movement. The output rod of the electric push rod 5, through the connecting rod 8 connected to it, effectively transmits its linear thrust to the latch 6. The latch 6 is then pushed forward. The limiting groove 9 on one side of the latch 6 engages with the limiting vertical rod 11 inside the sliding groove 10 on the side of the transmission rod 4. This allows the limiting groove 9 of the latch 6 to slide along the path defined by the limiting vertical rod 11. As the latch 6 is pushed, its end slides forward along the limiting vertical rod 11 within the sliding groove 10 of the transmission rod 4, thus engaging the limiting vertical rod 11 with the limiting groove 9, ultimately locking the toilet seat 1 relative to the seat ring 3. The entire mounting frame is securely installed on one side of the seat ring 3 using two locking screws 7 at its bottom. The process is reversed when unlocking is required. The output rod of the electric push rod 5 retracts, thereby separating the limiting vertical rod 11 from the limiting groove 9, thus releasing the constraint on the toilet seat 1 connecting block 2, and the toilet seat 1 can be freely lifted.

[0044] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
