DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments, all of which do not depart from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes and not for limiting the present invention.

[0020] To further illustrate the principle and structure of the present invention, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0021] Refer to Figures 1 to 3, an embodiment of the present application provides a diaphragm energy accumulator 30, which is used for a toilet, especially a smart toilet, to store the pressure in the toilet hydraulic system and change the water flow pressure in the toilet waterway. The diaphragm energy accumulator 30 of this embodiment includes an energy storage housing 31, an energy storage channel 32, a diaphragm 33, and an adjusting rod 34.

[0022] Among them, both ends of the energy storage housing 31 are open and the interior is hollow. The two open ends of the energy storage housing 31 are respectively a first port 311 and a second port 312. The two open ends of the energy storage channel 32 are used to communicate with the pipeline of the toilet, and the interior of the energy storage channel 32 allows water flow to pass through. A connection port 321 is provided on the energy storage channel 32, and the connection port 321 is connected to the second port 312 to enable the interior of the energy storage channel 32 to communicate with the interior of the energy storage housing 31.

[0023] The diaphragm 33 covers and seals the first port 311 of the energy storage housing 31. When water flows through the energy storage channel 32, an air chamber 35 is formed between the diaphragm 33 and the energy storage housing 31. The diaphragm 33 includes a flexible member 331, and the flexible member 331 has a first position protruding from the first port 311 of the energy storage housing 31 and a second position recessed inside the energy storage housing 31.

[0024] The adjusting rod 34 is connected to the flexible member 331, and the adjusting rod 34 can move relative to the energy storage housing 31 to drive the flexible member 331 to move between the first position and the second position, so that the flexible member 331 protrudes from the first port 311 of the energy storage housing 31 or is recessed inside the energy storage housing 31, thereby increasing or decreasing the volume of the air chamber 35.

[0025] Furthermore, the energy storage housing 31 of this embodiment includes an outer housing 313 and a transition body 314 connected to the outer housing 313, and the outer housing 313 and the transition body 314 can be integrally formed.

[0026] In this embodiment, the outer housing 313 is a cylindrical structure with both ends open and the interior hollow. The transition body 314 is a conical structure with both ends open and the interior hollow. Among them, the large port of the transition body 314 is connected to one end of the outer housing 313, and the port of the outer housing 313 facing away from the transition body 314 constitutes the first port 311 of the energy storage housing 31.

[0027] The small port of the transition body 314 constitutes the second port 312 of the energy storage housing 31, and the small port of the transition body 314 is connected to the connection port 321 of the energy storage channel 32 to achieve the communication between the energy storage channel 32 and the interior of the energy storage housing 31.

[0028] The energy storage channel 32 of this embodiment can be integrally formed with the energy storage housing 31 to ensure the overall structural strength of the diaphragm energy storage device 30. The two ports of the energy storage channel 32 are respectively an energy storage inlet 322 and an energy storage outlet 323, and the energy storage channel 32 is connected to the pipeline of the toilet. Water flows into the energy storage channel 32 from the energy storage inlet 322 and then flows out from the energy storage outlet 323.

[0029] In this embodiment, a connection port 321 is provided on the side wall of the energy storage channel 32. The second port 312 of the energy storage housing 31 is connected to the inside of the energy storage channel 32 through the connection port 321. The water flow entering the energy storage channel 32 can enter the inside of the energy storage housing 31 through the connection port 321.

[0030] The path of the connection port 321 extending into the energy storage channel 32 is conical, that is, the flow area of the path of the connection port 321 extending into the energy storage channel 32 shows a gradually decreasing trend. This setting can cause the water flow in the energy storage channel 32 to enter the energy storage housing 31 through the connection port 321. Based on the gradual change of the flow area of the connection port 321 corresponding to the energy storage channel 32, an instantaneous water pressure change is correspondingly generated to achieve an instantaneous change in the water pressure in the pipeline.

[0031] Furthermore, the diaphragm energy storage device 30 of this embodiment further includes an extension shell 36, and the extension shell 36 is arranged on the outer peripheral side of the first port 311 of the energy storage housing 31. The extension shell 36 can be integrally formed with the energy storage housing 31 to enhance the overall structural stability of the diaphragm energy storage device 30.

[0032] In this embodiment, the outer diameter of the extension shell 36 is larger than the outer diameter of the energy storage housing 31. The extension shell 36 of this embodiment is a cylindrical structure with both ends open and hollow inside. The end of the extension shell 36 is bent and connected to the outside of the energy storage housing 31 so that the outer wall of the extension shell 36 and the outer wall of the energy storage housing 31 form a stepped structure.

[0033] The end of the energy storage housing 31 partially extends into the inside of the extension shell 36. There is a gap between the outer wall of the energy storage housing 31 and the extension shell 36, and the gap between the outer wall of the energy storage housing 31 and the extension shell 36 forms a clamping position 361, and the clamping position 361 is annular.

[0034] In this embodiment, the diaphragm 33 is arranged at the first port 311 of the energy storage housing 31. The diaphragm 33 of this embodiment includes a flexible member 331 and a membrane member 332. The membrane member 332 is annular and is arranged around the periphery of the flexible member 331.

[0035] The flexible member 331 is made of a flexible material, and the flexible material can be rubber, silica gel, etc. Under the action of an external force, the flexible member 331 can undergo corresponding deformation. The flexible member 331 is connected inside the membrane member 332, and the outer peripheral edge of the membrane member 332 is bent.

[0036] The bent outer peripheral edge of the membrane member 332 is clamped between the outer wall of the energy storage housing 31 and the extension housing 36 to form a clamping position 361, so that the diaphragm 33 is fixed at the first port 311 of the energy storage housing 31, thereby blocking the diaphragm 33 on the first port 311 of the energy storage housing 31. An air chamber 35 is formed between the diaphragm 33 and the energy storage housing 31.

[0037] When the flexible member 331 of the diaphragm 33 is in the first position, the flexible member 331 protrudes from the surface of the membrane member 332 and protrudes outward from the first port 311 of the energy storage housing 31. At this time, the accommodation of the air chamber 35 increases. When the flexible member 331 of the diaphragm 33 is in the second position, the flexible member 331 is recessed in the membrane member 332 and recessed into the interior of the energy storage housing 31. At this time, the accommodation of the air chamber 35 decreases.

[0038] The adjusting rod 34 of this embodiment is connected to the flexible member 331 of the diaphragm 33. The adjusting rod 34 includes a rod main body 341 and a connecting body 342 connected to the end of the rod main body 341.

[0039] Among them, the outer contour of the connecting body 342 is circular, and the connecting body 342 is fixed on the outer surface of the flexible member 331. In this embodiment, the connecting body 342 can be screwed or adhesively fixed to the flexible member 331. The connection method between the connecting body 342 and the flexible member 331 is not limited too much here, as long as the stable connection between the adjusting rod 34 and the flexible member 331 can be ensured.

[0040] The adjusting rod 34 of this embodiment can move relative to the energy storage housing 31, and the connecting body 342 drives the flexible member 331 to deform, so that the flexible member 331 protrudes from the first port 311 of the energy storage housing 31 or is recessed into the interior of the energy storage housing 31, so that the flexible member 331 moves between the first position and the second position, thereby increasing or decreasing the volume of the air chamber 35.

[0041] Further, the diaphragm type energy storage device 30 of this embodiment further includes an energy storage outer cover 37, and the energy storage outer cover 37 is arranged on the extension housing 36. The energy storage outer cover 37 includes an outer cover body 371 and an extension body 372. Among them, the outer cover body 371 is a disc-shaped structure, and the extension body 372 is a cylindrical structure with both ends open and hollow inside. The outer diameter of the extension body 372 is smaller than the outer diameter of the outer cover body 371.

[0042] One end of the extension body 372 is connected to the surface of the outer cover body 371, and there are intervals between the peripheral edge of the outer cover body 371 and the outer side wall of the peripheral side of the extension body 372. The other end of the extension body 372 extends into the interior of the extension housing 36, so that the end of the extension housing 36 abuts against the inner surface of the outer cover body 371.

[0043] In this embodiment, an extension hole 3711 is formed in the outer cover body 371. The rod body 341 of the adjusting rod 34 passes through the interior of the extension body 372 and is disposed in the extension hole 3711 of the outer cover body 371. A convex edge 3712 is provided on the outer surface of the outer cover body 371 at the periphery of the extension hole 3711, and the convex edge 3712 provides guidance for the movement of the adjusting rod 34.

[0044] The energy storage outer cover 37 of this embodiment further includes a plurality of extension arms 373, and the plurality of extension arms 373 are spaced apart and disposed at the periphery of the outer cover body 371. The end of the extension arm 373 away from the outer cover body 371 is an L-shaped structure, and this L-shaped structure is snap-fitted on the stepped structure formed by the outer wall of the extension shell 36 and the outer wall of the energy storage shell 31, so that the energy storage outer cover 37 is stably connected to the extension shell 36.

[0045] When the energy storage outer cover 37 is snap-fitted on the extension shell 36 through the extension arms 373, the end of the extension body 372 on the energy storage outer cover 37 abuts against the membrane member 332 of the diaphragm 33, applying a pressing force to the membrane member 332, so that the membrane member 332 is tightly snap-fitted in the snap-fitting position 361 formed between the inner wall of the extension shell 36 and the outer wall of the energy storage shell 31, ensuring the overall structural strength and structural stability of the diaphragm energy storage device 30.

[0046] When the diaphragm energy storage device 30 of this embodiment is in use, the water flow in the toilet pipeline enters the energy storage channel 32 from the energy storage inlet 322 and then flows out from the energy storage channel 32. During the process of the water flow flowing through the energy storage channel 32, the water flow can enter the interior of the energy storage shell 31 from the connection port 321, blocking and compressing the original air in the air chamber 35 to form an air spring. When the pressure at the energy storage outlet 323 rises, the liquid level in the air chamber 35 rises, and the air in the air chamber 35 is compressed, thereby absorbing the energy generated by the change in water pressure and realizing the storage of energy by the air chamber 35.

[0047] By moving the adjusting rod 34 relative to the energy storage shell 31, the flexible member 331 can protrude from the first port 311 of the energy storage shell 31 or recess into the interior of the energy storage shell 31, so that the volume of the air chamber 35 changes accordingly. The change in the volume of the air chamber 35 will cause a change in the elastic coefficient of the air spring formed inside the air chamber 35, so as to release or absorb the water pressure energy correspondingly, thereby causing a change in the water pressure in the pipeline.

[0048] For the diaphragm energy storage device for a toilet in this embodiment, when water flows through the energy storage channel, an air chamber is formed between the diaphragm and the energy storage housing. The adjusting rod moves relative to the energy storage housing, and can drive the flexible member to protrude from the first port of the energy storage housing or recess into the interior of the energy storage housing, so that the volume of the air chamber changes. The air chamber of the diaphragm energy storage device can be used to store energy. When the energy stored in the diaphragm energy storage device is released, the water pressure can be increased, so that the water pressure changes in a fluctuating manner. Compared with setting a booster pump in the toilet hydraulic system, the diaphragm energy storage device does not need to be powered, the operation is relatively simple, the cost is low, and it is convenient for the operator to maintain.

[0049] Although the present invention has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary rather than restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but should be construed broadly within the spirit and scope defined by the appended claims. Therefore, all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
