Abstract

This utility model discloses a flow regulation structure for a push-type water spout, including a valve body, a water outlet channel, and a push handle. The main feature is a mounting hole on the valve body that communicates with the water outlet channel. A throttling rod, rotatable around its own axis, is installed within this mounting hole. A radially protruding convex shaft is also provided in the middle of the throttling rod, which serves to axially limit and rotate the throttling rod. The lower end of the throttling rod extends into the water outlet channel and has a water passage hole.

Description

Technical Field

[0001] This utility model relates to a flow regulation structure, specifically a flow regulation structure for a push cup spout. Background Technology

[0002] Currently, push-type water spouts mainly consist of a valve body, a water outlet channel within the valve body, and a push handle at the front of the valve body that opens and closes the water outlet channel. In other words, the push-type water spout uses a water container to push the handle to control the opening and closing of the water outlet channel. However, the water outlet channel itself does not have a flow rate adjustment design, resulting in a fixed flow rate. Therefore, in actual use, users can only indirectly control the water flow rate by adjusting the angle of the push handle. This adjustment method has significant drawbacks. For example, some water outlet channels are designed for a large flow rate, but if the user's water container has a small capacity, if the user applies too much force to the push handle, the water outlet channel will completely release its flow rate, quickly filling the container and causing a large amount of water to overflow and waste. Obviously, it is difficult to accurately control the water flow rate using only the push handle. Furthermore, the adjustment precision of the push handle is low, the operation is not convenient, and it also leads to water waste, reducing the product's water-saving performance. Therefore, existing push-type water spouts can no longer meet users' needs for precise water use and efficient operation. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a flow regulation structure for a push cup spout that can achieve high-precision flow regulation of the water outlet channel, is easy to operate, and effectively improves the water-saving performance of the product.

[0004] The technical problem of this utility model is solved by the following technical solution:

[0005] A flow regulation structure for a push-type water spout includes a valve body, a water outlet channel disposed within the valve body, and a push handle disposed at the front end of the valve body for opening and closing the water outlet channel. The valve body has a mounting hole communicating with the water outlet channel, and a throttling rod rotatable about its own axis is disposed within the mounting hole. The throttling rod has a radially protruding cam shaft in the middle, which serves to limit the axial movement and provide rotational sealing of the throttling rod. The lower end of the throttling rod extends into the water outlet channel and has a water passage hole. The throttling rod rotates around its own axis in a sealed manner, causing a change in the overlapping area of ​​the water passage hole and the water outlet channel to achieve flow regulation.

[0006] The lower shoulder of the cam shaft abuts against the limiting shoulder on the inner wall of the mounting hole via a sealing ring fitted outside the throttle rod. The upper shoulder of the cam shaft is abutted by a fastening nut screwed into the mounting hole, thereby achieving axial limiting and sealed rotation of the throttle rod within the mounting hole.

[0007] The lower end of the fastening nut is an external thread end that is screwed into the mounting hole, and the upper end is a fastening end that is exposed through the mounting hole. The fastening nut has an axially penetrating inner hole, and the upper end of the throttle rod is exposed through the inner hole.

[0008] The upper end of the throttle rod is provided with a drive groove, which is a straight groove, a cross-shaped groove, or a polygonal groove, and the throttle rod is driven to rotate around its own axis through the drive groove.

[0009] The flow rate adjustment increases as the area of ​​the overlapping region between the water inlet and the water outlet increases.

[0010] The centerline of the water passage and the centerline of the water outlet are on the same horizontal plane, and the overlapping area of ​​the water passage and the water outlet is the largest. The centerline of the water passage overlaps with the centerline of the water outlet, and the overlapping area of ​​the water passage and the water outlet is the smallest. The centerline of the water passage is perpendicular to the centerline of the water outlet.

[0011] The centerline of the mounting hole is perpendicular to the centerline of the water outlet channel.

[0012] The throttling rod is a cylindrical rod, and the water passage hole is a radial through hole located at the lower end of the throttling rod.

[0013] The fastening end is a regular polygonal block protruding outside the mounting hole, and the diameter of the circumscribed circle of the regular polygonal block is larger than the diameter of the mounting hole.

[0014] The rear end of the valve body is mounted on the top of the mounting rod, and the bottom end of the mounting rod is provided with a mounting seat.

[0015] Compared with existing technologies, this utility model mainly features a mounting hole on the valve body that communicates with the water outlet channel. A throttling rod, rotatable around its own axis, is located within this mounting hole. A radially protruding convex shaft is also provided in the middle of the throttling rod, which serves to axially limit and rotate the throttling rod. The lower end of the throttling rod extends into the water outlet channel and has a water passage hole. Thus, when the throttling rod rotates around its own axis, the overlapping area between the water passage hole and the water outlet channel changes, thereby regulating the flow rate of the water outlet channel. Clearly, the improved structure can achieve high-precision flow rate regulation of the water outlet channel through the added throttling rod. This regulation is unaffected by the push handle operation, making the operation very convenient and effectively improving the product's water-saving performance. Therefore, it better meets users' needs for precise water use and efficient operation. Attached Figure Description

[0021] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] A flow regulation structure for a push cup spout, such as Figure 1 As shown, it is mainly used to precisely adjust the water flow rate of the water outlet channel 11 inside the push cup spout, that is, to ensure that the adjusted water outlet channel 11 has a suitable water flow rate; in this way, even if the user applies too much force on the push handle 2, the water flow rate of the water outlet channel 11 can still be kept at a suitable level, thereby preventing a large amount of water from overflowing and being wasted from the water container.

[0024] The valve body is mounted on the top of the mounting rod 6 at the rear end, and the mounting rod is provided with a mounting seat 7 at the bottom end to facilitate the installation of the push cup spout. The valve body is mounted with a push handle 2 at the front end, so the user can control the opening and closing of the water outlet channel 11 by pushing the push handle 2 with a water container.

[0025] The water outlet channel 11 is a cylindrical channel horizontally placed inside the valve body 1, which mainly serves to allow water and other media to pass through. The valve body 1 is provided with a mounting hole 12 that communicates with the water outlet channel 11, and the axis of the mounting hole is perpendicular to the axis of the water outlet channel, thus forming a connecting structure with a cross-section of "┴".

[0026] The mounting hole 12 is equipped with a throttling rod 3 that can rotate around its own axis. The throttling rod is a cylindrical rod with a radially protruding, coaxial disc-shaped convex shaft 31 in the middle. That is, the throttling rod is similar to a cylindrical stepped shaft. The convex shaft 31 is used to achieve axial limiting and rotational sealing of the throttling rod 3. Specifically, the lower shoulder 312 of the convex shaft 31 abuts against the limiting shoulder 121 on the inner wall of the mounting hole 12 via a sealing ring 4 fitted outside the throttling rod 3. The upper shoulder 311 of the convex shaft 31 is abutted by a fastening nut 5 threaded into the mounting hole 12. This achieves axial limiting and sealed rotation of the throttling rod 3 in the mounting hole 12. In other words, the sealing ring 4 can achieve sealing performance between the throttling rod 3 and the mounting hole 12 during rotation and prevent the throttling rod from moving axially downward in the mounting hole 12. The fastening nut 5 can prevent the throttling rod 3 from moving axially upward in the mounting hole 12.

[0027] The lower end of the throttling rod 3 extends into the water outlet channel 11 and is provided with a water passage hole 32. This water passage hole is a radial through hole located at the lower end of the throttling rod 3, and the axis of the water passage hole 32 and the axis of the water outlet channel 11 are exactly on the same horizontal plane. Thus, when the throttling rod 3 rotates around its own axis, it will cause the overlapping area of ​​the water passage hole 32 and the water outlet channel 11 to change, thereby realizing the flow regulation of the water outlet channel 11. Generally, the flow regulation increases as the overlapping area of ​​the water passage hole and the water outlet channel increases. For example, when the overlapping area is the largest, the axis of the water passage hole and the axis of the water outlet channel exactly overlap, that is, the throttling rod completely releases the flow of the water outlet channel. When the overlapping area is the smallest, which usually means that there is no overlapping area at all, the axis of the water passage hole and the axis of the water outlet channel are exactly perpendicular, that is, the throttling rod completely closes the water outlet channel, forming a valve-like closing effect.

[0028] The fastening nut 5 is a cylindrical sleeve with an external thread end 51 at its lower end, which is screwed into the internal thread of the mounting hole 12. The upper end is a fastening end 52 that protrudes through the mounting hole 12. The fastening end is a regular polygonal block protruding outside the mounting hole 12. The diameter of the circumscribed circle of the regular polygonal block is larger than the diameter of the mounting hole 12. In this embodiment, the fastening end 52 is a regular hexagonal block protruding outside the mounting hole 12. The regular hexagonal block facilitates the tightening or loosening of the fastening nut 5 in the mounting hole 12.

[0029] The fastening nut 5 has an axially penetrating inner hole 53. The upper end of the throttle rod 3 can pass through the inner hole 53 and be exposed. The inner hole is a round hole with a diameter slightly larger than the outer diameter of the throttle rod but smaller than the outer diameter of the cam shaft. In other words, an appropriate gap is reserved between the throttle rod 3 and the inner hole. This ensures axial positioning while also facilitating the flexible rotation of the throttle rod. It also allows for easy operation of the exposed upper end of the throttle rod with the help of tools, thereby driving the throttle rod 3 to rotate around its own axis within the mounting hole 12 to achieve flow regulation.

[0030] The upper end of the throttle rod 3 is also provided with a drive groove 33. The drive groove is a straight groove, a cross-shaped groove, or a polygonal groove engraved on the upper surface. The depth of the drive groove 33 is matched with the size of tools such as standard wrenches or screwdriver heads to facilitate operation. Alternatively, a fixed block or handle-shaped operating component can be designed directly on the upper end of the throttle rod to replace the tool for operation.

[0031] This invention enables high-precision flow regulation of the water outlet channel 11 through a sealed rotating throttle rod 3. This regulation is not affected by the operation of the push handle 2, and the operation of the throttle rod 3 is also very convenient. Therefore, by regulating the flow of the water outlet channel 11, the water-saving performance of the product can be effectively improved, thereby better meeting the user's needs for precise water use and efficient operation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the utility model as claimed. The scope of protection of this utility model is defined by the appended claims and their equivalents.
