Description

Technical Field

[0001] This utility model relates to the field of bathroom product technology, and more specifically, to a stop structure and a valve core. Background Technology

[0002] As bathroom products become increasingly feature-rich, the use of switching valve cores is also becoming more widespread. To enhance the feel of shifting gears, a gear shifting structure is often incorporated into the valve core. For example, Chinese patent CN205534379U discloses a four-way switching valve with a slot on the upper side of the mounting base. A ball bearing is placed within this slot, and a spring is positioned below the ball bearing within the slot. The valve core housing has shifting grooves at intervals on its top surface that mate with the ball bearing. The ball bearing and shifting grooves engage movably to improve the feel of shifting gears. However, the spring and ball bearing shifting structure is relatively large. Placing it within the valve core cavity would affect the internal structure layout and hinder valve core design. If the spring and ball bearing were placed on the valve stem, the stem size would increase, making valve core assembly difficult and limiting the faucet's appearance. Utility Model Content

[0003] This utility model discloses a stop structure, which aims to improve the problem that the existing valve core stop structure is too large and not conducive to the internal structure design of the valve core.

[0004] The present invention adopts the following solution:

[0005] A stop structure includes a mounting base, a ball, a spring, and a transmission component. The mounting base has a mounting groove on its side wall for accommodating the ball. The spring is disposed on the outside of the mounting base to force the ball to move inward along the mounting groove. The transmission component is mounted on the inside of the mounting base and has a stop groove on its side wall. The mounting base or the transmission component can be rotated in an operable manner so that the ball is movably engaged with the stop groove under the action of the spring.

[0006] As a further improvement, the mounting base is provided with an inner hole, the assembly groove communicates with the inner hole, and the transmission component is sleeved in the inner hole.

[0007] As a further improvement, the mounting base is symmetrically provided with two mounting slots along the diameter direction of the inner hole, and each mounting slot is provided with a ball.

[0008] As a further improvement, a mounting groove is recessed along the outer side wall of the mounting base, and the spring piece is embedded in the mounting groove.

[0009] As a further improvement, the transmission component is connected to the valve stem to drive the moving ceramic disc to rotate synchronously with the valve stem.

[0010] As a further improvement, multiple stop slots are arranged in an array along the circumferential direction of the transmission component.

[0011] As a further improvement, the depth of the stop groove is less than the radius of the marble, and its sidewall is inclined outward.

[0012] As a further improvement, the marble is a stainless steel ball.

[0013] As a further improvement, the spring is C-shaped.

[0014] Another valve core is provided, including a valve core body, wherein the valve core body is provided with a stop structure as described in any of the preceding claims.

[0015] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0016] This application utilizes the lever principle to press a fixed spring against a ball, forcing the ball to embed into a gear slot under the pressure of the spring, forming a mechanical lock. When the mounting base or transmission component rotates, the ball slides out of one gear slot under the constraint of the mounting groove and can embed into another gear slot under the action of the spring, generating audible and tactile feedback to prompt the operator and complete the function switch. In this process, the ball is both the locking element for gear shifting and the transmission element for gear shifting. The spring provides the necessary elasticity to ensure that the ball remains in the gear slot and undergoes a certain elastic deformation when the ball slides out of the gear slot, allowing the ball to smoothly disengage from the gear slot. The gear shifting structure of this application, using a ball and spring, can be set on the side of the mounting base and transmission component. The mounting base can be the valve core housing or other components inside the valve core. Compared with the prior art, it eliminates the need for spring travel space, has a smaller structural size, and its setting position is less restricted by size, thus facilitating the internal structural design of the valve core.

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example

[0032] Combination Figures 1 to 7This embodiment provides a stop structure, including a mounting base 1, a ball 2, a spring 3, and a transmission component 4. The mounting base 1 has an assembly groove 11 on its side wall for accommodating the ball 2. The spring 3 is disposed on the outside of the mounting base 1 to force the ball 2 to move inward along the assembly groove 11. The transmission component 4 is mounted on the inside of the mounting base 1 and has a stop groove 41 on its side wall. The mounting base 1 or the transmission component 4 can be rotated in an operable manner so that the ball 2 can be movably engaged with the stop groove 41 under the action of the spring 3.

[0033] It should be noted that a fixed spring plate 3 is pressed onto the ball 2 using the lever principle, forcing the ball 2 to embed into the gear position groove 41 under the pressure of the spring plate 3, forming a mechanical lock. When the mounting base 1 or the transmission component 4 rotates, the ball 2 slides out of one gear position groove 41 under the restriction of the mounting groove 11, and can embed into another gear position groove 41 under the action of the spring plate 3, forming a gear position sound and tactile feedback to prompt the operator and complete the function switch. In this process, the ball 2 is both the locking element for the gear position and the transmission element for gear switching. The spring plate 3 provides the necessary elasticity to ensure that the ball 2 can always remain in the gear position groove 41, and when the ball 2 slides out of the gear position groove 41, it produces a certain elastic deformation so that the ball 2 can smoothly disengage from the gear position groove 41. The stop structure in this embodiment uses a ball 2 and a spring 3, which can be set on the side of the mounting base 1 and the transmission component 4. The mounting base 1 can be the valve core shell or other components inside the valve core. Compared with the prior art, there is no need for the spring travel space, the structure size is small, and the setting position is less restricted by size, which is beneficial to the internal structural design of the valve core.

[0034] In a preferred embodiment, the mounting base 1 has an inner hole 12, and the mounting groove 11 communicates with the inner hole 12. The transmission component 4 is sleeved in the inner hole 12. A mounting groove 13 is recessed along the outer side wall of the mounting base 1, and the spring 3 is embedded in the mounting groove 13. For example, the ball 2 is a stainless steel ball, and the spring 3 is a C-shaped stainless steel sheet. Under the action of its own elasticity, it is embedded in the mounting groove 13. The cross-sectional shape of the mounting groove 13 is also C-shaped to restrict the rotation of the spring 3. The stainless steel material can ensure the performance of the ball 2 and the spring 3, ensure the life of the gear shift structure, and is beneficial for installation in various products. In addition, in products that do not require gear shifting, the spring 3 can be removed from the outside to improve the versatility of the valve core.

[0035] Furthermore, the mounting base 1 has two symmetrically formed mounting slots 11 along the diameter of the inner hole 12, and each mounting slot 11 is equipped with a ball 2. The two balls 2 can slide out or insert into the gear slot 41 at the same time, which can enhance the gear shifting feel.

[0036] Based on the above embodiments, in an optional embodiment of this utility model, the transmission component 4 is connected to the valve stem 5 to drive the moving ceramic disc to rotate synchronously with the valve stem 5. For example, the transmission component 4 is fixed to the valve stem 5 by a pin 51 and is provided with a driving part adapted to the groove on the moving ceramic disc, so that the moving ceramic disc can be driven to rotate synchronously when the valve stem 5 is rotated, thereby realizing the valve core gear switching.

[0037] Preferably, multiple stop slots 41 are arranged in an array along the circumference of the transmission component 4. The depth of the stop slot 41 is less than the radius of the ball 2, and its sidewalls are inclined outward to facilitate the insertion and sliding out of the ball 2, ensuring smooth gear switching. For example, the transmission component 4 is provided with 6 stop slots 41, with a 60° interval between two adjacent stop slots 41. The transmission component 4 can switch gears every 60° rotation, and the corresponding ball 2 slides out of one stop slot 41 and falls into another stop slot 41.

[0038] This utility model also provides a valve core, including a valve core body, which has a stop structure as described in any of the above embodiments. For example, the mounting base 1 is the outer shell of the valve core body, the spring 3 is sleeved on the outer wall of the outer shell, and the transmission member 4 is sleeved in the inner hole 12 of the outer shell and connected to the valve stem 5. By rotating the valve stem 5, the transmission member 4 is driven to rotate relative to the outer shell, so that the ball 2 slides out or is embedded in the stop groove 41 to form a stop switching reminder. This is not limited to this and is not specifically limited. It should be mentioned that placing the spring 3 on the outer wall of the shell can reduce the occupation of the stop structure on the internal space of the valve core, thus making the internal structure design of the valve core more favorable.

[0039] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.
