Description

Technical Field

[0001] This application relates to the field of shower equipment components, and in particular to a flow control cup. Background Technology

[0002] A rubber cup is a component widely used in water supply systems such as showers. Made of rubber, it has a certain degree of elasticity. A through hole is opened in the center of the rubber cup, and a rotating shaft can be inserted into the center of the rubber cup and fixedly connected to it. By rotating or sliding, the rubber cup can move inside the pipe, thereby controlling the flow of water in the pipe.

[0003] The existing water cup includes a cylinder and an end cap. The end cap is fixed to one end face of the cylinder. A central hole is opened at the center of the end cap. A flow hole is opened on the end cap for water flow. When the water cup is installed in the water supply system, the outer wall of the cylinder abuts against the inner wall of the water pipe. A rotating shaft is connected to the central hole on the end cap. The rotating shaft drives the end cap to rotate until the flow hole is connected to the water pipe, and the water can flow smoothly in the pipe.

[0004] The aforementioned technical solutions have the following drawbacks: the rubber cup can only be used to control the on / off state of the pipe, and it is difficult to control the flow rate of the water flowing out of the pipe. It is necessary to install an additional flow control device in the shower equipment, which results in a larger size of the shower equipment. Utility Model Content

[0005] To reduce the size of shower equipment, this application provides a flow control cup.

[0006] The present application provides a flow control cup with the following technical solution:

[0007] A flow control cup includes a rubber ring, which comprises a cylinder and an end cap. The end cap is connected to one side wall of the cylinder. The cylinder and the end cap are integrally formed. A central hole is formed at the center of the end cap, and the central hole penetrates the end cap. Multiple flow holes are formed on the end cap, and the multiple flow holes are arranged along the circumference of the end cap. An adjusting rubber material is provided in the flow holes. The adjusting rubber material is made of an elastic rubber material and has a cylindrical structure. The adjusting rubber material is coaxially fixed in the flow holes.

[0008] By adopting the above technical solution, and by opening multiple flow holes on the end cap, when the user installs the rubber ring in the shower equipment, the rotating shaft can be inserted into the central hole and a bolt can be installed on the rotating shaft to drive the rubber ring to rotate. This causes the flow holes at different positions on the rubber ring to be located on the water flow path, so that the water flows through different flow holes. When the water flows in the flow holes, the water flow applies pressure to the regulating rubber material, causing the regulating rubber material to deform. By using regulating rubber materials made of different elastic materials, the cross-sectional area of ​​the water flow in each flow hole is different, thereby achieving the effect of controlling the water flow rate. By installing the rubber ring in the shower equipment, the user can control the rotation of the rubber ring, thereby achieving the effect of controlling the water flow interruption and flow rate.

[0009] Optionally, the flow holes are arranged in pairs, with two flow holes in each pair, and the two flow holes in the same pair are located on both sides of the end cap.

[0010] By adopting the above technical solution, multiple flow holes are opened on the end cap, so that the same pair of flow holes can be connected to the pipe at the same time. When it is necessary to rotate the rubber ring, the user can rotate it at a small angle to allow water to flow through different flow holes.

[0011] Optionally, the end cap is provided with a sealing blind hole, which is located on the side of the end cap near the cylinder.

[0012] By adopting the above technical solution, a sealing blind hole is opened on the end cap, so that the position of the sealing blind hole from the center of the end cap is equal to the position of the flow hole from the center of the end cap. Thus, when the rubber ring rotates, the sealing blind hole can rotate to the water flow channel and block the channel, thereby achieving the effect of controlling the water flow interruption. The rubber ring can be slidably connected to the rotating shaft, and a return spring is provided on the rotating shaft. The return spring pushes the end cap, so that the surface of the end cap abuts against the end of the water outlet pipe. When the water outlet pipe is inserted into the sealing blind hole, the water flow in the water outlet pipe cannot continue. When the rotating shaft drives the rubber ring to rotate until the water outlet pipe is inserted into the flow hole, the water flow in the water outlet pipe can continue.

[0013] Optionally, an inner sealing ring is provided in the central hole. The inner sealing ring has a circular structure and is coaxially arranged with the end cover. Multiple inner sealing rings are provided and spaced apart along the thickness direction of the end cover.

[0014] By adopting the above technical solution, and by setting an inner sealing ring in the central hole, when the rotating shaft is inserted into the central hole, the inner sealing ring is squeezed and deformed, thereby sealing the gap between the rubber ring and the rotating shaft and improving the sealing performance of the connection between the rubber ring and the rotating shaft.

[0015] Optionally, an outer sealing ring is provided on the outer side of the cylinder. The outer sealing ring has a circular structure and is coaxially connected to the cylinder. Multiple outer sealing rings are provided and spaced apart along the length of the cylinder.

[0016] By adopting the above technical solution, and by setting an outer sealing ring on the outside of the cylinder, when the rubber ring is inserted into the water pipe, the outer sealing ring on the outer wall of the rubber ring abuts against the pipe, thereby improving the sealing performance between the water pipe and the outer wall of the rubber ring.

[0017] Optionally, the end cap is provided with an inner sleeve, which is located on the side of the end cap near the cylinder.

[0018] By adopting the above technical solution, by setting an inner sleeve on the end cap, when the rotating shaft is inserted into the center hole of the end cap, the inner sleeve is fitted on the outer wall of the rotating shaft, thereby increasing the contact area between the rotating shaft and the rubber ring, increasing the frictional force connecting the rotating shaft and the rubber ring, reducing the probability of the rubber ring rotating on the rotating shaft, and improving the positional accuracy of the rubber ring rotation.

[0019] Optionally, the inner wall of the inner sleeve is inclined inward.

[0020] By adopting the above technical solution, by opening an inclined surface on the inner sleeve, when the rotating shaft is inserted into the central hole, the inner sleeve deforms and fits tightly against the outer wall of the rotating shaft, thereby improving the sealing performance between the rubber ring and the rotating shaft.

[0021] Optionally, the cylinder is provided with an outer sleeve, the outer wall of which is inclined outward.

[0022] By adopting the above technical solution, by setting an outer sleeve on the cylinder, when the rubber ring is inserted into the water pipe, the outer sleeve can be deformed and fit against the inner wall of the water pipe, thereby improving the sealing performance of the connection between the rubber ring and the water pipe.

[0023] In summary, the beneficial technical effects of this application are as follows:

[0024] 1. By opening multiple flow holes on the end cap, when the user installs the rubber ring in the shower equipment, the rotating shaft can be inserted into the central hole and a bolt can be set on the rotating shaft to drive the rubber ring to rotate. This allows the flow holes at different positions on the rubber ring to be located on the water flow path, so that the water flows through different flow holes. When the water flows in the flow holes, the water flow applies pressure to the regulating rubber material, causing the regulating rubber material to deform. By using regulating rubber materials made of different elastic materials, the cross-sectional area of ​​the water flow in each flow hole is different, thereby achieving the effect of controlling the water flow rate. By installing the rubber ring in the shower equipment, the user can control the rotation of the rubber ring, thereby achieving the effect of controlling the water flow interruption and flow rate.

[0025] 2. By setting an inner sealing ring in the center hole, when the rotating shaft is inserted into the center hole, the inner sealing ring is squeezed and deformed, thereby sealing the gap between the rubber ring and the rotating shaft and improving the sealing performance at the connection between the rubber ring and the rotating shaft;

[0026] 3. By setting an inner sleeve on the end cap, when the shaft is inserted into the center hole of the end cap, the inner sleeve is fitted on the outer wall of the shaft, thereby increasing the contact area between the shaft and the rubber ring, increasing the friction between the shaft and the rubber ring, reducing the probability of the rubber ring rotating on the shaft, and improving the positional accuracy of the rubber ring rotation.

[0033] The present application will be further described in detail below with reference to the accompanying drawings.

[0034] This application discloses a leather cup for flow control, referring to... Figure 1 , Figure 2 and Figure 3The system includes a rubber ring 1, which comprises a cylinder 11 and an end cap 12. The cylinder 11 has a cylindrical structure, and the end cap 12 is located on one side of the cylinder 11. The cylinder 11 and the end cap 12 are integrally formed. The rubber ring 1 is made of elastic rubber. The rubber ring 1 is placed inside the water pipe, with the outer wall of the cylinder 11 abutting against the inner wall of the water pipe. A central hole 123 is provided at the center of the end cap 12, through which a rotating shaft is inserted. A bolt can be installed on the rotating shaft to clamp the end cap 12, thereby enabling the rotating shaft to drive the rubber ring 1 to rotate. The end cap 12 has multiple flow holes 121. When the end cap 12 rotates, it rotates and causes water to flow through different flow holes 121, achieving the effect of controlling the water flow rate.

[0035] Reference Figure 3 Multiple outer sealing rings 111 are provided on the outer wall of the cylinder 11. The outer sealing rings 111 are circular rings and are coaxially arranged with the cylinder 11. Multiple outer sealing rings 111 are provided and spaced apart along the length of the cylinder 11. When the rubber ring 1 is inserted into the water pipe, the outer sealing rings 111 abut against the inner wall of the water pipe, thereby sealing the gap between the water pipe and the rubber ring 1 and reducing the probability of water leakage between the water pipe and the rubber ring 1.

[0036] Reference Figure 1 and Figure 2 The flow holes 121 are arranged in pairs. In this embodiment, there are two pairs of flow holes 121, with two flow holes 121 in each pair. The two flow holes 121 in the same pair are respectively opened on both sides of the end cap 12. The two pairs of flow holes 121 are at a 45-degree angle to each other. By rotating the rubber ring 1, the user can make the water flow through different pairs of flow holes 121 to adjust the water flow rate.

[0037] Reference Figure 3 , Figure 4 and Figure 5 An adjusting rubber material 125 is provided inside the flow hole 121. The adjusting rubber material 125 is made of elastic rubber. The adjusting rubber material 125 has a cylindrical structure and is coaxially arranged inside the flow hole 121. The adjusting rubber material 125 in different pairs of flow holes 121 has different elasticity. When water flows in the flow hole 121, the water flow applies pressure to the adjusting rubber material 125, causing the adjusting rubber material 125 to deform. When water flows in different pairs of flow holes 121 with the same water pressure, the cross-sectional area of ​​the flow hole 121 is different, thus resulting in different water flow rates. The user can control the water flow rate by allowing the water to flow through the flow holes 121 with different adjusting rubber materials 125, making it convenient to use.

[0038] Reference Figure 2The end cap 12 has a sealing blind hole 122, which is located on the side surface of the end cap 12 near the cylinder 11. There are two sealing blind holes 122, and the line connecting the centers of the two sealing blind holes 122 passes through the center of the end cap 12. The distances from the center of the sealing blind hole 122 and the center of the flow hole 121 to the center of the end cap 12 are equal. When the user rotates the rubber ring 1, the sealing blind hole 122 can be placed in the outlet hole inside the water pipe, thereby blocking the water flow.

[0039] Reference Figure 3 An inner sealing ring 124 is provided inside the central hole 123. The inner sealing ring 124 is a circular ring structure and is coaxially arranged inside the central hole 123. Multiple inner sealing rings 124 are provided and are equidistantly spaced along the thickness direction of the end cover 12. When the rotating shaft is inserted into the central hole 123 and connected to the rubber ring 1, the inner sealing ring 124 abuts against the rotating shaft, which can reduce the probability of water leakage between the end cover 12 and the rotating shaft.

[0040] Reference Figure 3 The rubber ring 1 is provided with an inner sleeve 2, which is set inside the cylinder 11. One end of the inner sleeve 2 is connected to the end cap 12. The inner wall of the inner sleeve 2 is inclined inward. When the rotating shaft is inserted into the central hole 123, the inner sleeve 2 fits against the side wall of the rotating shaft, further reducing the chance of water leakage between the rubber ring 1 and the rotating shaft.

[0041] Reference Figure 3 The rubber ring 1 is provided with an outer sleeve 3, which is located on the side of the cylinder 11 away from the end cap 12. The outer sleeve 3 is a cylindrical structure with its outer wall inclined outward. When the rubber ring 1 is inserted into the water pipe, the outer sleeve 3 abuts against the inner wall of the water pipe, thereby reducing the chance of water leakage between the rubber ring 1 and the water pipe.

[0042] The implementation principle of this application embodiment is as follows: by opening a central hole 123 at the center of the end cap 12, a rotating shaft can be connected to the central hole 123, thereby causing the rotating shaft to drive the rubber ring 1 to rotate. During the rotation of the rubber ring 1, the position of the flow hole 121 on the rubber ring 1 changes, thereby allowing water to flow through different flow holes 121. An adjusting material 125 is provided in the flow hole 121. When the water flows, the water squeezes the adjusting material 125, causing the adjusting material 125 to deform, thereby causing the cross-section of the water flow to be different. By bonding and setting adjusting materials 125 with different elasticities in the flow hole 121, the water flow can pass through different flow holes 121 on the end cap 12, thereby achieving the effect of controlling the water flow rate.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
