Description

Technical Field

[0001] This utility model relates to the technical field of water supply products, and in particular to a flow regulating device for a flexible hose. Background Technology

[0002] Common water-dispensing devices such as shower heads, spray guns, or pull-out faucets are usually connected to the faucet via a flexible hose, and the water flow is controlled by turning the faucet on and off during use.

[0003] When it is necessary to adjust the water flow, one hand usually needs to hold the shower head or spray gun at one end of the hose, and the other hand needs to reach to the other end of the hose to control the opening of the faucet to control the flow. The operation is relatively troublesome and difficult. Furthermore, the opening of the internal valve core is not easy to adjust when turning the faucet handle, and the stability of the control is limited. Moreover, the control accuracy is difficult to guarantee, and it is impossible to accurately adjust the water flow.

[0004] Existing solutions, such as the adjustable flow rate anti-tangle hose disclosed in Chinese Utility Model Patent CN 221075653 U and the adjustable flow rate hose device disclosed in Chinese Utility Model Patent CN 221300476 U, can all achieve adjustment and control of the outflow water. In view of this, the applicant proposes a hose flow rate adjustment device with an alternative structure, which can solve the aforementioned problem of difficulty in adjusting the flow rate. Utility Model Content

[0006] To achieve the above objectives, the solution of this utility model is:

[0007] A flow regulating device for a hose includes a connector, a connector seat, a movable valve core, a fixed valve core, and an adjusting component;

[0008] The connector, connector base and hose are connected in sequence, and the end of the connector away from the hose is the connection interface for connecting the water outlet device.

[0009] The movable valve core is rotatably disposed within the connector, and the fixed valve core is non-rotatably disposed within the connector seat, with the movable valve core abutting against the fixed valve core; the movable valve core has a movable hole, and the fixed valve core has a fixed hole; the inner cavity of the hose, the fixed hole, the movable hole, and the connection interface constitute a water passage.

[0010] The outer wall of the connector has a circumferentially extending adjustment groove that connects to the interior of the connector. The adjustment element is rotatably disposed on the outside of the connector and is connected to the movable valve core through the adjustment groove. The rotation of the adjustment element drives the movable valve core to rotate, and makes the movable hole and the fixed hole aligned or misaligned with each other, so as to change the water flow rate of the water passage by changing the water flow area between the movable hole and the fixed hole.

[0011] Furthermore, the end face of the movable valve core near the fixed valve core has two circumferentially spaced movable holes; the end face of the fixed valve core near the movable valve core has two circumferentially spaced fixed holes; when the movable valve core rotates, the two movable holes can overlap with the two fixed holes, at which time the water passage has the maximum flow rate, and the two movable holes can also be perpendicular to and misaligned with the two fixed holes to form a water passage gap, at which time the water passage has the minimum flow rate.

[0012] Furthermore, the adjustment groove restricts the rotation angle of the adjustment component and the movable valve core to within 90 degrees.

[0013] Furthermore, the adjusting component is a hollow sleeve fitted around the outer periphery of the connector, and an adjusting retaining ring is provided between the adjusting component and the connector; an inner retaining block and an outer retaining block protrude from the inner and outer sides of the adjusting retaining ring respectively; the inner retaining block passes through the adjusting groove and engages with a concave hole provided on the outer wall of the movable valve core, and the inner retaining block can move circumferentially within the adjusting groove; the outer retaining block engages with a retaining hole on the inner side wall of the adjusting component.

[0014] Furthermore, the adjusting ring has an opening, and the inner and outer locking blocks are two symmetrically arranged along the opening.

[0015] Furthermore, a hollow rotating core is provided between the connector and the hose; one end of the rotating core is fixedly connected to the hose, and the other end is rotatably inserted into the connector.

[0016] Furthermore, the outer peripheral wall of the connector near the connector seat has an external thread and a protruding tongue on the outer peripheral surface of the end face; the connector seat has a recessed slot for the tongue to be inserted; a rotating sleeve is also fitted over the connector seat; the inner opening of the rotating sleeve near the connector head has an internal thread that is screwed into the external thread of the connector head; the inner wall of the rotating sleeve has a radially protruding locking step, and the outer wall of the connector seat has an external flange, which is located between the locking step and the connector head; the adjusting member is also fitted around the outer periphery of the rotating sleeve; wear-resistant rings are fitted on the upper and lower edges of the adjusting member respectively.

[0017] Furthermore, the outer peripheral wall of the adjusting member is provided with anti-slip texture.

[0018] Furthermore, the fixed valve core includes an upper valve body and a lower valve body that are fastened together; the top surface of the lower valve body has a protrusion, and the bottom surface of the upper valve body has a recess for the protrusion to be inserted and positioned; the bottom of the lower valve body is provided with a positioning block, and the inner wall of the connecting seat is provided with a positioning groove for the positioning block to be inserted; the upper valve body is made of wear-resistant material.

[0019] Furthermore, the upper valve body is made of EPDM material.

[0020] After adopting the above technical solution, this utility model is installed on one end of the hose via a connecting seat. When in use, the connecting interface of the connector is screwed to a shower head, kitchen faucet, spray gun, or other water outlet device. When using the handheld water outlet device, the flow rate of the hose can be easily adjusted by rotating the adjustment component nearby.

[0021] When the adjusting component rotates circumferentially along the adjusting groove, it can drive the movable valve core to rotate circumferentially inside the connector, causing the movable hole to move circumferentially, thereby aligning or misaligning with the fixed hole, thus changing the water passage area between the two, and ultimately achieving precise regulation of the water passage flow.

[0022] The adjustment method of this utility model is simple and convenient. The movable valve core and the fixed valve core abut against each other, and they are not easily moved by the impact of water flow after they rotate relative to each other, which can ensure that the adjusted flow rate is stable and reliable.

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0038] like Figures 1 to 11 As shown, a flow regulating device 10 for a flexible hose in this embodiment includes a connector 1, a connector 2, a movable valve core 3, a fixed valve core 4, and an adjusting component 5.

[0039] The connector 1, connector 2, and hose 20 are connected in sequence. The end of the connector 1 away from the hose 20 is the connection interface 11 for connecting the water outlet device. In this embodiment, the connection interface 11 is a threaded connector, but it is not limited to this. A sealing ring 111 may also be provided inside the connection interface 11 to facilitate sealing and prevent leakage.

[0040] The movable valve core 3 is rotatably disposed within the connector 1, and the fixed valve core 4 is non-rotatably disposed within the connector 2, with the movable valve core 3 abutting against the fixed valve core 4; the movable valve core 3 has a movable hole 31, and the fixed valve core 4 has a fixed hole 41; the inner cavity 201 of the hose 20, the fixed hole 41, the movable hole 31, and the connector 11 constitute a water passage.

[0041] The outer wall of the connector 1 has a circumferentially extending adjustment groove 12, which connects to the interior of the connector 1. The adjustment member 5 is rotatably disposed on the outside of the connector 1 and is connected to the movable valve core 3 through the adjustment groove 12. The rotation of the adjustment member 5 drives the movable valve core 3 to rotate, and makes the movable hole 31 and the fixed hole 41 aligned or misaligned with each other, so as to change the water flow rate of the water passage by changing the water flow area between the movable hole 31 and the fixed hole 41.

[0042] Therefore, in this embodiment, the flow regulating device 10 is installed on one end of the hose 20 via the connector 2, and in use, the shower head 30 is screwed to the connector 11 of the connector 1 (see...). Figure 12 The hose 20 serves as the shower head inlet pipe, and the kitchen faucet pull-out head 40 (see...) Figure 13 The hose 20 serves as the pull tube of the pull-out head 40, a water outlet device for spray guns, etc. When using the handheld water outlet device, the flow rate of the hose 20 can be easily adjusted by rotating the adjusting component 5 nearby. When the adjusting component 5 rotates circumferentially along the adjusting groove 12, it drives the movable valve core 3 to rotate circumferentially inside the connector 1, causing the movable hole 31 to move circumferentially, thereby aligning or misaligning with the fixed hole 41, thus changing the water passage area between the two, and ultimately achieving precise adjustment of the flow rate of the water passage. The flow rate adjustment device 10 of this embodiment has a simple and convenient adjustment method, and the movable valve core 3 and the fixed valve core 4 abut against each other. After they rotate relative to each other, they are not easily moved by the water flow impact, ensuring that the adjusted flow rate is stable and reliable.

[0043] In this embodiment, the end face of the movable valve core 3 near the fixed valve core 4 has two circumferentially spaced movable holes 31, which extend towards the other end and converge into a single outlet hole 32; the end face of the fixed valve core 4 near the movable valve core 3 has two circumferentially spaced fixed holes 41, which can directly penetrate both ends of the fixed valve core 4; when the movable valve core 3 rotates, the two movable holes 31 can overlap with the two fixed holes 41 (e.g., ...). Figure 6 and Figure 7 At this point, the water passage has the maximum flow rate. When the movable valve core 3 rotates further, the two movable holes 31 can also be perpendicular to and misaligned with the two fixed holes 41 to form a water passage gap S (e.g., Figure 9 and Figure 10At this point, the water passage has a minimum flow rate. Of course, the number of movable holes 31 and fixed holes 41 is not limited to this, and can be set to one or more as needed.

[0044] In this embodiment, in order to facilitate the adjustment and positioning of the maximum and minimum flow rates of the movable valve core 3, the adjustment groove 12 can be set to limit the rotation angle of the adjustment member 5 and the movable valve core 3 to within 90 degrees. Thus, when the adjustment member 5 rotates back and forth 90 degrees, it can switch between the two states of maximum and minimum flow rates, making the adjustment convenient and easy.

[0045] like Figure 2 As shown, the adjusting member 5 in this embodiment is a hollow sleeve fitted around the outer periphery of the connector 1 to facilitate rotation control.

[0046] An adjusting ring 6 may also be provided between the adjusting component 5 and the connector 1; the adjusting ring 6 has an inner locking block 61 and an outer locking block 62 protruding from its inner and outer sides respectively; the inner locking block 61 passes through the adjusting groove 12 and engages with the concave hole 33 provided on the outer wall of the movable valve core 3, and the inner locking block 61 can move circumferentially within the adjusting groove 12; the outer locking block 62 engages with the locking hole 51 on the inner side wall of the adjusting component 5. Thus, when the adjusting component 5 rotates circumferentially around the connector 1, the outer locking block 62 can drive the adjusting ring 6 to rotate, while the inner locking block 61 on the inner side of the adjusting ring 6 can move within the adjusting groove 12 and drive the movable valve core 3 to rotate, thereby realizing the change of angle between the movable hole 31 and the fixed hole 41.

[0047] In this embodiment, the adjusting ring 6 has an opening 63 to facilitate its assembly onto the connector 1; the inner locking block 61 and the outer locking block 62 are two symmetrically arranged along the opening 63 to improve structural stability. The corresponding connector 1 also has two adjusting grooves 12.

[0048] like Figure 3 and Figure 4 In this embodiment, a hollow rotating core 7 may be provided between the connecting seat 2 and the hose 20; one end of the rotating core 7 is fixedly connected to the hose 20, and the other end is rotatably inserted into the connecting seat 2. This allows the flow regulating device 10 to rotate relative to the hose 20, which can prevent tangling.

[0049] like Figure 2 and Figure 4The connector 1 has an external thread 13 on its outer peripheral wall near the connector seat 2, and a tongue 14 protrudes from the outer peripheral wall of its end face. In this embodiment, two tongues 14 are symmetrically arranged. The connector seat 2 has a recessed slot 21 for the tongue 14 to be inserted into, thereby realizing the snap-fit ​​positioning of the connector 1 and the connector seat 2. The connector seat 2 is also fitted with a rotating sleeve 8. The rotating sleeve 8 has an internal thread 82 in its sleeve opening 81 near the connector 1, which is screwed into the external thread 13 of the connector 1. The inner wall of the rotating sleeve 8 has a radially protruding snap-fit ​​step 83, and the outer wall of the connector seat 2 has an external flange 22, which is limited between the snap-fit ​​step 83 and the connector 1. The rotating sleeve 8 can be used to lock the connector 1, and the snap-fit ​​step 83 can be used to limit the connector seat 2. Thus, the rotating sleeve 8 can be used to fix the connector 1 and the connector seat 2. At the same time, the rotating sleeve 8 can also cover the end of the hose 20 to protect the end of the hose 20.

[0050] The adjusting member 5 can be simultaneously fitted around the outer periphery of the rotating sleeve 8, that is, the adjusting member 5 can fit over the connection between the connector 1 and the connector 2; the upper and lower edges of the adjusting member 5 are respectively fitted with wear-resistant rings 9 to improve the wear resistance of the adjusting member 5.

[0051] Furthermore, the outer peripheral wall of the adjusting member 5 may be provided with anti-slip texture 52 to facilitate the rotation of the adjusting member 5 and prevent slippage when wet.

[0052] like Figure 4 , Figure 5 and Figure 11 As shown, the fixed valve core 4 may include an upper valve body 42 and a lower valve body 43 that are fastened together. The top surface of the lower valve body 43 has a protrusion 431, and the bottom surface of the upper valve body 42 has a recess 421 for the protrusion 431 to be inserted and positioned. The protrusion 431 and the recess 421 can be used to fasten and fix the upper valve body 42 and the lower valve body 43 and prevent relative rotation between them in the circumferential direction.

[0053] The lower valve body 43 is provided with a positioning block 432 at the bottom, and the inner wall of the connecting seat 2 is provided with a positioning groove 23 for the positioning block 432 to be inserted into; so as to restrict and prevent the fixed valve core 4 from rotating circumferentially relative to the connecting seat 2.

[0054] In this embodiment, the upper valve body 42 is made of wear-resistant material, specifically EPDM (ethylene propylene diene trimer), which has good wear resistance and self-lubricating effect, and is easy to manufacture, thus reducing tolerances.

[0055] Meanwhile, the structure of this embodiment is detachable, which allows for easy replacement and maintenance of the upper valve body 42, effectively extending the product's service life.

All technical solutions falling within the scope of this utility model's concept are protected by this utility model.
