Description

Technical Field

[0001] The present invention relates to the technical field of toilet covers, and particularly to an integrated cleaning cover plate. Background Art

[0002] The integrated cleaning cover plate integrates a cleaning device (i.e., a bidet) on the seat ring and uses the water spraying function to clean the target object, providing a convenient sanitary cleaning experience for users.

[0003] In the prior art, the connection mode between the cleaning device and the external water supply source is usually as follows: an external hose is connected to the internal cleaning device through the seat ring. For example, the utility model patent with the patent number 202020360073.2 discloses an integrated cover plate assembly, specifically discloses that a water inlet joint is provided at the rear side of the seat ring, and the water inlet joint includes a water inlet pipe and a water outlet pipe. Among them, the water inlet pipe is externally connected to the water supply source, and the water outlet pipe is inserted into the water inlet of the valve body.

[0004] In actual use, when it is necessary to clean the toilet surface, the toilet cover and the seat ring need to be turned upwards to expose the upper surface of the toilet for cleaning operations. During this process, the water inlet joint and the external hose connected thereto will move together with the seat ring. Since the seat ring flipping operation is relatively frequent, the external hose will be continuously pulled for a long time. Over time, the hose is extremely likely to be damaged, broken, etc., which will affect the normal water supply of the cleaning device, resulting in the product being unable to be used normally, and at the same time increasing the maintenance cost and the use cost. Summary of the Invention

[0005] The purpose of the present invention is to provide an integrated cleaning cover plate with a simple structure to solve the problem of the external hose of the cleaning device following rotation.

[0006] To achieve the above object, the solution of the present invention is: an integrated cleaning cover plate, including a mounting seat, a toilet cover, a seat ring and a cleaning device;

[0007] The mounting seat is fixed on the toilet, and at least one fixed rotating shaft is fixedly provided on the mounting seat. The fixed rotating shaft is fixed to the mounting seat, and the rear ends of the toilet cover and the seat ring are both rotatably connected to the fixed rotating shaft and rotate relative to the toilet around the fixed rotating shaft;

[0008] The cleaning device is installed at the rear end of the seat ring and rotates up or down relative to the toilet following the seat ring; the cleaning device includes a water outlet assembly and a control assembly, and the control assembly is connected to the water outlet assembly and controls its water outlet state;

[0009] The inside of the fixed rotating shaft is a water passing channel. The outer end of the fixed rotating shaft is connected to the external pipeline, and the inner end is connected to the water outlet assembly. A communicating water path is formed between the water passing channel, the external pipeline and the water outlet assembly, so as to connect the external water source to the water outlet assembly.

[0010] Furthermore, a left shaft sleeve and a right shaft sleeve are provided on the mounting base, a middle shaft cylinder is provided at the rear end of the seat ring, and a left shaft cylinder and a right shaft cylinder are provided at the rear end of the toilet lid. These shaft sleeves and shaft cylinders are coaxially arranged; the shaft sleeves and shaft cylinders on the same side of the mounting base, the seat ring and the toilet lid are connected by the fixed rotating shaft.

[0011] Furthermore, a positioning groove extending along the axial direction of the fixed rotating shaft is provided on the outer periphery of the fixed rotating shaft, and a positioning convex block is provided on the inner wall of the shaft sleeve on which the fixed rotating shaft is installed. The positioning groove and the positioning convex block cooperate to limit the circumferential rotation of the fixed rotating shaft within the shaft sleeve.

[0012] Furthermore, a limiting groove extending along the axial direction of the fixed rotating shaft is provided on the outer periphery of the fixed rotating shaft, and the side wall of the shaft sleeve on which the fixed rotating shaft is installed has a limiting hole. A limiting member passes through the limiting hole and is embedded in the limiting groove of the fixed rotating shaft to limit the axial movement of the fixed rotating shaft within the shaft sleeve.

[0013] Furthermore, a damping shaft is provided between the shaft sleeves and shaft cylinders on the other side of the mounting base, the seat ring and the toilet lid.

[0014] Furthermore, the cross-section of the mounting base is L-shaped. The shaft sleeve is located on the vertical part of the L-shaped mounting base, and the horizontal part is the fixing part. The fixing part cooperates with the bolts on the toilet to fix the mounting base on the toilet.

[0015] Furthermore, an external thread section for connecting to an external pipeline is provided at the outer end of the fixed rotating shaft, and an airtight seal is formed between the inner end and the water outlet assembly through a sealing member.

[0016] Furthermore, a sealing cover is provided on the side of the water outlet assembly away from the seat ring. The outer periphery of the sealing cover is fixed below the seat ring. The sealing cover and the seat ring enclose the water outlet assembly and provide a closed space for the water passage of the water outlet assembly.

[0017] Furthermore, the water outlet assembly includes an integral water outlet body, which is fixed below the seat ring. The water outlet body is provided with a water inlet channel, a valve cavity and at least two water outlet channels. The valve cavity is located between the water inlet channel and the water outlet channels. The valve cavity is provided with a water inlet hole and at least two water outlet holes. The water inlet hole is communicated with the water inlet channel, and each water outlet hole is communicated with a water outlet channel; an anti-siphon assembly is provided on each water outlet channel.

[0018] Furthermore, the control assembly includes a knob, a valve rod and a valve core. The valve core is arranged in the valve cavity. The knob is arranged outside the seat ring. The knob is connected to the valve core through the valve rod, and the rotation of the valve core is controlled by operating the knob, so as to realize the opening and closing of the water outlet waterway and the regulation of the flow rate.

[0019] After adopting the above scheme, the beneficial effects of the present invention are as follows:

[0020] Simple structure and no dead corners for cleaning: Compared with the existing structures, the present invention does not need to design a separate rear seat for installing the cleaning device. The cleaning device is fixed on the seat ring, with a simple structure and no dead corners for toilet cleaning.

[0021] The water inlet pipeline does not rotate: In the present invention, by combining the fixed rotating shaft with the water inlet pipeline, that is, using the internal channel of the fixed rotating shaft as the water inlet channel. Since the fixed rotating shaft is fixed on the mounting seat and will not move with the flipping of the seat ring, the external hose can remain relatively stationary. This effectively avoids a series of problems that may be caused by the rotation of the water inlet pipeline, such as the winding, abrasion, leakage of the external pipeline, and the influence on the smooth flipping of the cover plate. It ensures the stability and reliability of the toilet cover plate during long-term use, extends the service life of the product, and reduces the maintenance cost.

[0022] No internal hose connection in series: The water outlet body of the cleaning device is reasonably arranged with water channel passages, without the need to set an internal hose, which can avoid the easy leakage points and messy internal structures caused by the connection of the internal hose, and can also save the mold cost, reduce the production cost, and make the product more competitive in price.

[0023] Built-in integrated anti-siphon structure: The water outlet assembly is built-in with an integrated anti-siphon structure, which can effectively prevent the phenomenon of water backflow caused by abnormal fluctuations in the pressure of the external water supply system, the restoration of water supply after a water outage, etc. Description of the Drawings

[0046] The following will make a detailed description of the present invention in conjunction with the accompanying drawings and specific embodiments.

[0047] The present invention provides an integrated cleaning cover plate, as Figures 1 to 12As shown in the figure, it includes a mounting base 1, a toilet lid 2, a seat ring 3, and a cleaning device. The mounting base 1 is fixed on the toilet. The toilet lid 2 and the seat ring 3 are rotatably connected to the mounting base 1, so they can be turned up and down relative to the toilet. The cleaning device is installed below the seat ring 3 and can be turned synchronously with the seat ring 3. The present invention ingeniously uses the fixed rotating shaft 4 fixed to the mounting base 1 as the water inlet pipeline of the cleaning device. In the traditional integrated cleaning cover plate design, the water inlet pipeline usually needs to be set separately and needs to move accordingly with the turning of the seat ring 3, which easily causes problems such as winding, twisting, or even breaking of the water inlet pipeline during the turning process. However, in the present invention, by combining the fixed rotating shaft 4 with the water inlet pipeline, the water inlet pipeline no longer needs to rotate additionally, thus effectively avoiding a series of problems caused by the water inlet pipeline following the rotation, such as pipeline wear, water leakage, and affecting the smoothness of the cover plate turning.

[0048] The mounting base 1 is an important component for installing the toilet lid 2 and the seat ring 3 on the toilet. In this embodiment, as Figure 1 and Figure 2 shown, the cross-section of the mounting base 1 is L-shaped, with its rear end being the horizontal part and the front end being the vertical part. The horizontal part is the fixed part 13, and the fixed part 13 can cooperate with the bolts inherent in the toilet to firmly install the mounting base 1 on the toilet. The form of the fixed part 13 is not limited to the specific structure shown in the figure. As long as it can achieve the function of cooperating with the toilet for installation, the fixed part 13 can adopt any reasonable design.

[0049] As Figure 4 shown, the vertical part of the mounting base 1 is provided with bushings, including a left bushing 11 and a right bushing 12. Correspondingly, the rear end of the seat ring 3 is provided with a middle shaft cylinder 31, and the rear ends of the toilet lid 2 are provided with a left shaft cylinder 21 and a right shaft cylinder 22. These bushings and shaft cylinders are coaxially arranged. The middle shaft cylinder 31 of the seat ring 3 is located between the left bushing 11 and the right bushing 12 of the mounting base 1, and the left shaft cylinder 21 and the right shaft cylinder 22 of the toilet lid 2 are respectively located outside the left bushing 11 and the right bushing 12 of the mounting base 1.

[0050] On at least one side of the left and right sides of the rotational connection of the mounting base 1, the seat ring 3, and the toilet lid 2, a fixed rotating shaft 4 is provided, and the seat ring 3 and the toilet lid 2 can rotate around the fixed rotating shaft 4. In this embodiment, as Figures 3 to 6 shown, the fixed rotating shaft 4 is passed through between the bushing and the shaft cylinder on the right side. The fixed rotating shaft 4 is fixedly installed on the right bushing 12 of the mounting base 1, and there is no relative rotation between the fixed rotating shaft 4 and the right bushing 12.

[0051] For the convenience of later maintenance, replacement, disassembly, and assembly, the fixed rotating shaft 4 and the mounting base 1 are not designed to be integrally formed, but are designed to be detachable. As Figure 3 and Figure 6As shown, a positioning groove 41 extending along the axial direction is provided on the outer periphery of the fixed rotating shaft 4, and a positioning projection 14 is provided on the inner wall of the right shaft sleeve 12 of the mounting seat 1. The positioning groove 41 cooperates with the positioning projection 14 to limit the circumferential rotation of the fixed rotating shaft 4 within the right shaft sleeve 12. In addition, in order to prevent the fixed rotating shaft 4 from disengaging from the right shaft sleeve 12, as shown in the figure, a limiting groove 42 extending along the axial direction of the fixed rotating shaft 4 is provided on the outer periphery of the fixed rotating shaft 4. The side wall of the shaft sleeve on which the fixed rotating shaft 4 is installed has a limiting hole 15. A limiting member passes through the limiting hole 15 and is embedded in the limiting groove 42 of the fixed rotating shaft 4 to limit the axial movement of the fixed rotating shaft 4 within the shaft sleeve.

[0052] Both ends of the fixed rotating shaft 4 serve as the rotating shafts of the toilet lid 2 and the seat ring 3 respectively. As Figure 6 and Figure 7 shown, the outer end of the fixed rotating shaft 4 extends out of the outer end of the right shaft sleeve 12 and is inserted into the right shaft cylinder 22 of the toilet lid 2, and the inner end of the fixed rotating shaft 4 extends out of the inner end of the right shaft sleeve 12 and is inserted into the middle shaft cylinder 31 of the seat ring 3. In this way, the toilet lid 2 and the seat ring 3 can rotate relative to the toilet up and down around the fixed rotating shaft 4, as Figure 8 shown.

[0053] On the left side of the rotational connection between the mounting seat 1 and the seat ring 3 and the toilet lid 2, it is connected by a damping shaft 7, which can achieve the damped opening and closing of the toilet lid 2 and the damped opening and closing of the seat ring 3. As Figure 3 and Figure 4 shown, a first damping shaft 71 is provided between the left shaft sleeve 11 of the mounting seat 1 and the left shaft cylinder 21 of the toilet lid 2, and a second damping shaft 72 is provided between the left shaft sleeve 11 of the mounting seat 1 and the middle shaft cylinder 31 of the seat ring 3. A damping fixing seat 8 is fixed in the middle of the left shaft sleeve 11 of the mounting seat 1, and the first damping shaft 71 and the second damping shaft 72 are respectively fixed on the left and right sides of the damping fixing seat 8. The damping shaft 7 adopted in this solution is any existing damping shaft on the market. This type of damping shaft has mature technology and stable performance. Its working principle is based on an internal damping mechanism (such as hydraulic damping, friction damping, etc.). Through the interaction between the damping medium and the moving parts, a certain resistance torque is generated, thereby realizing the control of the rotation speed. Since the damping shaft belongs to the prior art, the detailed working principle and structure of it will not be elaborated in this solution.

[0054] In this case, the cleaning device is installed at the rear end of the seat ring 3 and can integrally follow the seat ring 3 to rotate up or down relative to the toilet. Specifically, the cleaning device mainly includes a water outlet assembly 5 and a control assembly 6. The control assembly 6 is connected to the water outlet assembly 5 through a wire or other signal transmission methods and controls its water outlet state, including but not limited to the start and stop of water outlet, the flow rate, etc.

[0055] The inside of the above-mentioned fixed rotating shaft 4 is a water passing channel, which is a key component for introducing external water source into the water outlet assembly 5 in the cleaning device. AsFigure 6 and Figure 7 As shown, after the outer end of the fixed shaft 4 passes through the right shaft tube 22 of the toilet lid 2, it is fixedly connected to the external pipe. The external pipe mentioned here usually refers to the external hose. The connection method between the fixed shaft 4 and the external hose includes but is not limited to threaded connection, plug-in connection, etc. An escape space 32 is provided in the middle of the central shaft tube 31 of the seat ring 3. After the inner end of the fixed shaft 4 passes through the central shaft tube 31 of the seat ring 3, it is connected to the water outlet component 5 at the escape space 32. A seal is provided at the connection between the fixed shaft 4 and the water outlet component 5 to prevent water leakage. In addition, the water outlet component 5 and the fixed shaft 4 are not circumferentially limited, that is, driven by the seat ring 3, the water outlet component 5 can rotate relative to the fixed shaft 4, while the fixed shaft 4 remains stationary.

[0056] The water outlet assembly 5 of this solution is compact in structure and has no internal hose connection. Figures 7 to 10 As shown, the water outlet assembly 5 includes an integrated water outlet body 51, which is fixed below the seat ring 3. The water outlet body 51 is provided with a water inlet channel 511, a valve chamber 512 and two water outlet channels 513. The water inlet end of the water inlet channel 511 is connected to the inner end of the above-mentioned fixed rotating shaft 4, and the water paths inside the two are connected. The valve chamber 512 is located between the water inlet channel 511 and the water outlet channel 513. The valve chamber 512 is provided with a water inlet hole and two water outlet holes. The water inlet hole is connected to the water inlet channel 511, and each water outlet hole is connected to a water outlet channel 513. When water flows into the water inlet channel 511, it will enter the valve chamber 512 through the water inlet hole on the valve chamber 512. In the valve chamber 512, the water flow will be reasonably distributed according to the subsequent control operation, and then diverted to the two water outlet channels 513 through the water outlet hole on the valve chamber 512. A nozzle assembly 53 is provided at the tail of the water outlet channel 513. When the water flows through the water outlet channel 513 and reaches the nozzle assembly 53, it can be sprayed toward the target object, such as the private parts of the human body, at a suitable angle, pressure and form, thereby achieving an efficient and comfortable cleaning effect so that the water flow can be sprayed toward the target object.

[0057] The control component 6 includes a knob 61, a valve stem 62 and a valve core 63. The valve core 63 is arranged in the valve cavity 512, and the knob 61 is arranged on the outside of the seat ring 3. The knob 61 is connected to the valve core 63 through the valve stem 62, and the rotation of the valve core 63 is controlled by operating the knob 61, thereby realizing the opening and closing of the water outlet waterway and the regulation of the flow rate.

[0058] In order to prevent the cleaning device from back-sucking due to abnormal pressure fluctuations in the external water supply system, or when the water supply is restored after a water outage, an anti-siphon device is provided on each water outlet channel 513. Figures 7 to 12As shown, an anti-siphon chamber 514 is provided on the water outlet channel 513. An inlet through hole 5141 is opened below the anti-siphon chamber 514, and an outlet through hole 5142 is opened on the side. An anti-siphon assembly is provided in the anti-siphon chamber 514. The anti-siphon assembly mainly includes a water passing body 515 and an eccentric pad 516. A first water hole 5151 communicating with the inlet through hole 5141 and a second water hole 5152 communicating with the outlet through hole 5142 are opened on the water passing body 515. The eccentric pad 516 is rotatably arranged above the first water hole 5151 through a rotating shaft. When the eccentric pad 516 swings upward, the first water hole 5151 will be opened, and when the eccentric pad 516 swings downward, the first water hole 5151 will be blocked to prevent water flow through.

[0059] Under normal circumstances, referring to Figure 11 , the water flow upstream of the water outlet channel 513 flows from the inlet through hole 5141 to the first water hole 5151, pushes up the eccentric pad 516, and then flows out to the downstream of the water outlet channel 513 through the outlet through hole 5142 and the second water hole 5152, providing a stable water flow supply for the normal operation of the cleaning device. If a reverse flow occurs, referring to Figure 12 , the water flow in the water outlet channel 513 surges into the water passing body 515 from the water outlet channel 513 and the second water hole 5152. At this time, the water flow will press down the eccentric pad 516 to block the first water hole 5151, and the reverse flow of water cannot continue to enter the upstream part of the inlet through hole 5141 and the water outlet channel 513, effectively avoiding the phenomenon of water being sucked back into the external water supply pipeline.

[0060] As Figure 8 shown, a sealing cover 9 is provided on one side of the water outlet assembly 5 away from the seat ring 3. The outer periphery of the sealing cover 9 is fixed to the lower part of the seat ring 3, and the fixing methods include but are not limited to bolts, buckles, etc. The sealing cover 9 and the seat ring 3 enclose the water outlet assembly 5 and provide a closed space for the water channel of the water outlet assembly 5. The cover sealing cover 9 can also extend to the valve stem 62 to hide the valve stem 62, which not only improves the aesthetics of the product but also prevents components such as the valve stem 62 from being contaminated.
