Description

Technical Field

[0001] The present invention relates to the technical field of bathroom water saving, and particularly to a flow controller and a bubbler. Background Art

[0002] Currently, inside bathroom water outlet products such as faucets, shower heads or bubblers on the market, a flow control device is usually provided. The function of this flow control device is that when the water pressure of the incoming water reaches a certain level, the water outlet flow will not change with the increase of the water pressure, and the water output basically remains constant. Therefore, it can ensure that the water outlet product obtains the same flow under different water pressure conditions, making the water outlet effect of the water outlet product stable and ensuring water saving and comfort.

[0003] Among them, the Chinese utility model patent with the application number 201120571183.4 discloses a flow controller. This flow controller arranges an elastomer with a claw in a housing, and uses the claw to support the elastomer to keep the gap between the elastomer and the housing stable to keep the water pressure stable. However, when the water pressure is greater than the pressure limit that the claw can withstand, the claw will break, resulting in the damage of the flow controller. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a flow controller and a bubbler that can withstand high water pressure.

[0005] To solve the above technical problem, the technical solution adopted by the present invention is: a flow controller, including a housing and a sheet body. The bottom of the housing is provided with a water outlet hole, the top of the housing is an open end, the sheet body is located inside the housing, there is a water passing space between the sheet body and the bottom of the housing, the sheet body covers the water outlet hole, the sheet body is provided with elastic feet, the feet include at least two supporting feet and at least one suspended foot, the sheet body is supported on the bottom of the housing by the supporting feet, and there is a distance between the suspended foot and the bottom of the housing.

[0006] The beneficial effect of the present invention is that: an elastic-footed sheet body is used to withstand the water pressure. The supporting feet on the sheet body that support the bottom of the housing are used as the first-level supporting part, and the suspended feet on the sheet body are used as the second-level supporting part. When the water pressure borne by the sheet body is relatively large, the distance between the sheet body and the bottom of the housing becomes smaller, the suspended foot contacts the bottom of the housing, and the second-level supporting part starts to share the pressure borne by the first-level supporting part, thereby improving the ability of the sheet body to withstand the water pressure, avoiding the compression fracture of the feet on the sheet body, and increasing the service life of the flow controller.

[0013] To describe in detail the technical content, achieved purpose and effects of the present invention, the following is described in conjunction with the implementation manners and with reference to the drawings.

[0014] The most crucial concept of the present invention lies in: dividing the legs into multiple levels of support parts for hierarchically supporting the sheet body.

[0015] Please refer to Figures 1 - 5 , the flow controller provided by the present invention includes a housing and a sheet body. The bottom of the housing is provided with a water outlet hole. The top of the housing is an open end. The sheet body is located inside the housing. There is a water passing space between the sheet body and the bottom of the housing. The sheet body covers the water outlet hole. The sheet body is provided with elastic legs. The legs include at least two support legs and at least one suspended leg. The sheet body is supported on the bottom of the housing by the support legs. There is a gap between the suspended leg and the bottom of the housing.

[0016] The working principle of the present invention is as follows: The top of the housing serves as the water inlet end, and the water outlet hole at the bottom of the housing is the water outlet end. When there is no water pressure, the support legs on the sheet body that contact the bottom of the housing are the first-level support parts, and the suspended legs are the second-level support parts. During the water inlet process, the water at the water inlet end impacts the sheet body and flows from the space between the sheet body and the housing to the water outlet end. As the water pressure gradually increases, the distance between the sheet body and the bottom of the housing decreases under pressure, and the second-level support parts contact the bottom of the housing as the sheet body descends, sharing the pressure borne by the first-level support parts.

[0017] From the above description, it can be seen that the beneficial effects of the present invention are: a sheet body with elastic supporting feet is used to withstand water pressure, the supporting feet on the sheet body supported on the bottom of the shell are used as the first-level supporting part, and the suspended feet on the sheet body are used as the second-level supporting part. When the water pressure on the sheet body is large, the distance between the sheet body and the bottom of the shell becomes smaller, the suspended feet contact the bottom of the shell, and the second-level supporting part begins to share the pressure borne by the first-level supporting part, thereby improving the ability of the sheet body to withstand water pressure, avoiding the feet on the sheet body from being broken under pressure, and increasing the service life of the flow controller.

[0018] Furthermore, at least one column is provided between the bottom of the shell and the sheet-like body, the column is provided at the bottom of the shell, and the distance between the sheet-like body and the column is greater than the distance between the suspended support foot and the bottom of the shell.

[0019] From the above description, it can be seen that after all the legs are in contact with the bottom of the shell, when the sheet body continues to decline under the water pressure, the column serves as the last level of support to support the sheet body and prevent the sheet body from pressing down to close the water outlet at the bottom of the shell.

[0020] Furthermore, the water outlet holes are provided with separation ribs for separating the water outlet holes, and the column is arranged on the separation ribs.

[0021] From the above description, it can be known that the separation ribs are used to place the column so that the supporting position of the column is close to the center position of the sheet, thereby preventing the sheet from being offset when the column supports the sheet and affecting the flow control effect.

[0022] Furthermore, the number of the suspended legs is at least two, and the distances between the at least two suspended legs and the bottom of the shell are different.

[0023] From the above description, it can be seen that multiple suspended legs are arranged on the sheet body, and the suspended heights of the multiple suspended legs are different, serving as multi-level supports when the sheet body is subjected to water pressure impact. The legs on the sheet body share the pressure step by step to avoid the legs being broken due to excessive pressure.

[0024] Furthermore, the flow controller also includes an upper cover, on which a water hole is provided, and the upper cover is connected to the top of the shell.

[0025] As can be seen from the above description, the sheet-like body is placed between the upper cover and the shell to prevent the sheet-like body from being separated from the shell due to elastic action when subjected to water pressure impact.

[0026] Furthermore, a limiting rib for separating the water holes is provided on the water holes of the upper cover, a limiting column is provided on the limiting rib, the limiting column is located between the sheet body and the upper cover, and there is a gap between the limiting column and the sheet body.

[0027] As can be seen from the above description, a limiting rib is provided on the upper cover to separate the water passing holes, and a limiting post is provided on the limiting rib to limit the position of the sheet-like body, so that the sheet-like body will not be supported by the inner wall of the shell or displaced due to the impact of water pressure.

[0028] Furthermore, the upper cover is conical in shape, the water passing holes are arranged at the top of the upper cover, and at least one sub-water passing hole is arranged on the conical surface of the conical upper cover, and the size of the sub-water passing hole is smaller than that of the water passing hole.

[0029] As can be seen from the above description, the water passing holes are aligned with the center of the sheet-like body, and the sub-water passing holes on the conical surface face the direction of the sheet-like body, ensuring that when water enters, the large flow of the water passing holes directly flows towards the sheet-like body, and the water flow of the sub-water passing holes on the conical surface flows towards the sheet-like body.

[0030] Furthermore, at least one extension part is provided on the sheet-like body.

[0031] As can be seen from the above description, the extension part can expand the area of the sheet-like body that bears water pressure, improve the action range of the sheet-like body, and improve the stability of the water outlet flow rate.

[0032] Furthermore, a bubbler includes the flow controller.

[0033] As can be seen from the above description, installing the flow controller in the bubbler can be used to control the flow rate in the bubbler.

[0034] Please refer to Figures 1 - 3 , Embodiment 1 of the present invention is:

[0035] A flow controller provided by the present invention includes a housing 1 and a sheet-like body 2. An outlet hole 11 is provided at the bottom of the housing 1, and the top of the housing 1 is an open end;

[0036] The sheet-like body 2 is located inside the housing 1. There is a water passing space for water circulation between the sheet-like body 2 and the bottom of the housing 1. The sheet-like body 2 covers the outlet hole 11. Elastic feet are provided on the sheet-like body 2. The feet include three support feet 3 and a first suspended foot 4. The sheet-like body 2 is supported on the bottom of the housing 1 by the three support feet 3, and there is a distance between the first suspended foot 4 and the bottom of the housing 1.

[0037] Among them, the number of the support feet 3 can be two, three or more.

[0039] Among them, the distance between the first suspended support leg 4 and the bottom of the housing 1 is less than or equal to the ultimate deformation distance of the three support legs 3. The ultimate deformation distance of the three support legs 3 is the distance that the sheet body 2 descends when the three support legs 3 are fractured by water pressure. The distance between the first suspended support leg 4 and the bottom of the housing 1 is associated with the ultimate deformation distances of different numbers of support legs 3. According to specific requirements, when the number of support legs 3 is two, three or more, the ultimate deformation distance of the support legs 3 changes, and the distance between the first suspended support leg 4 and the bottom of the housing 1 also changes with the ultimate deformation distance of the support legs 3.

[0040] A partition rib for separating the water outlet holes is provided on the water outlet hole 11, and a column body 6 is provided on the partition rib. The column body 6 is located at the center of the water outlet hole 11, and the distance between the column body 6 and the sheet body 2 is greater than the distance between the first suspended support leg 4 and the bottom of the housing 1.

[0041] Among them, the number of column bodies 6 on the partition rib can be two, three or more, and the multiple column bodies 6 are centrosymmetric with respect to the water outlet hole 11.

[0042] The top of the housing 1 is fixedly connected to the upper cover 7. A water passing hole 12 is provided on the upper cover 7. A limiting rib 8 for separating the water passing hole is provided on the water passing hole 12. A limiting column 9 is provided on the limiting rib 8. The limiting column 9 extends in the water inlet direction, and there is a gap between the limiting column 9 and the sheet body 2.

[0043] Two extension parts 5 for increasing the area of the sheet body 2 are provided on the sheet body 2.

[0044] The sheet body 2, the two extension parts 5, the three support legs 3 and the first suspended support leg 4 are of an integral structure. The extension parts 5, the three support legs 3 and the first suspended support leg 4 are all located at the edge of the sheet body 2 and are spaced from each other.

[0045] The positions of the two extension parts 5 and the first suspended support leg 4 on the sheet body 2 are respectively located between the three support legs 3.

[0046] A bubbler includes a flow controller. Other components in the bubbler are the prior art content. Here, only the existing flow control component is replaced with the flow controller in this embodiment.

[0047] Please refer to Figure 4 and Figure 5 , the second embodiment of the present invention is:

[0048] Referring to the first embodiment, the difference between the second embodiment and the first embodiment is:

[0049] The sheet-like body 2 is provided with five feet and an extension part 5. The five feet include three supporting feet 3, a first suspended foot 4 and a second suspended foot 10. The distance between the first suspended foot 4 and the bottom of the housing 1 is less than the distance between the second suspended foot 10 and the bottom of the housing 1.

[0050] Among them, the number of the first suspended foot 4 and the second suspended foot 10 can both be three, four or more. The distances between the first suspended foot 4, the second suspended foot 10 and the bottom of the housing 1 are all different. According to specific requirements, a third suspended foot, a fourth suspended foot, etc. can also be set, and the distances between the first suspended foot 4, the second suspended foot 10, the third suspended foot, the fourth suspended foot and the bottom of the housing 1 are all different. It is used to form a multi-level supporting part and play a multi-level supporting role.

[0051] Among them, the distance between the first suspended foot 4 and the bottom of the housing 1 is less than or equal to the limit deformation distance of the three supporting feet 3, and the distance between the second suspended foot 10 and the first suspended foot 4 is less than or equal to the limit deformation distance of the first suspended foot 4. Similarly, in the case of setting a third suspended foot, a fourth suspended foot, etc., the distance between the third suspended foot and the second suspended foot 10 is less than or equal to the limit deformation distance of the second suspended foot 10, and the distance between the fourth suspended foot and the third suspended foot is less than or equal to the limit deformation distance of the third suspended foot.

[0052] The positions of the extension part 5, the first suspended foot 4 and the second suspended foot 10 on the sheet-like body 2 are respectively located between the three supporting feet 3.

[0053] The distance between the column 6 and the sheet-like body 2 is greater than the distance between the first suspended foot 4 and the bottom of the housing 1.

[0054] More precisely, the distance between the column 6 and the sheet-like body 2 is greater than the distance between any of the suspended feet and the bottom of the housing 1.

[0055] The upper cover 7 is conical. The water passing hole 12 is arranged at the top of the upper cover 7. A circular sub-water passing hole 13 is arranged on the conical surface of the upper cover. The size of the sub-water passing hole 13 is smaller than the size of the water passing hole 12.

[0056] A bubbler includes a flow controller. Other components in the bubbler are the content of the prior art. Here, only the existing flow control component is replaced with the flow controller in this embodiment.

[0057] The water flow direction in the flow controller of this embodiment is as Figure 5As shown by the arrow direction. Water enters the flow controller through the water passing holes in the upper cover, impacts the sheet body and flows from the space between the sheet body and the housing to the water outlet hole at the bottom of the housing. As the inlet water flow increases, the water pressure borne by the sheet body gradually increases, the supporting feet undergo elastic deformation, the sheet body descends and the distance between the sheet body and the bottom of the housing becomes smaller. The first suspended foot contacts the bottom of the housing as the sheet body descends to share the pressure borne by the supporting feet, preventing the supporting feet from being fractured under pressure. When the water pressure further increases, the second suspended foot contacts the bottom of the housing to share the pressure borne by the feet supported on the bottom of the housing, preventing the feet supported on the bottom of the housing from being fractured under pressure. After all the suspended feet contact the bottom of the housing and the sheet body still descends, the column serves as the last-level supporting part of the sheet body to ensure that the sheet body does not directly cover the water outlet hole. Each suspended foot at a different height serves as a level of supporting part, and as the sheet body descends, different levels of supporting parts gradually contact the bottom of the housing to support the sheet body.

[0058] In summary, a flow controller provided by the present invention is provided with supporting feet, suspended feet and a column to hierarchically support the sheet body. When the water pressure borne by the sheet body gradually increases, each level of support participates in the support step by step, preventing the feet from being fractured under pressure, ensuring the stable operation of the sheet body, and keeping the flow rate of the flow controller stable.

[0059] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in the related technical fields, shall be similarly included in the patent protection scope of the present invention.
