Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a handwheel of a water heating temperature control valve with a sound function. Background Technology

[0002] Existing thermostatic handwheels for plumbing valves typically lack gear positions, relying primarily on feel to determine the rotation position. Over time, this can lead to the handwheel becoming loose. A loose handwheel causes variations in valve opening and closing, making flow control difficult. An improved technology, such as the thermostatic handwheel described in application number 201120437394.9, includes a handwheel positioning ring for fixing to a thermostatic valve core, a handwheel guide seat, a handwheel housing with a first opening at the front end, a spring ring, and a splined sleeve for fixing to the rotating part of the thermostatic valve core. The handwheel guide seat is axially movable and located at the rear end of the handwheel positioning ring. The handwheel positioning ring has a first stop and a second stop. The handwheel guide seat has a limiting stop that cooperates with the first and second stops. The spring ring is located between the handwheel guide seat and the splined sleeve. The handwheel guide seat moves axially relative to the splined sleeve, compressing or releasing the spring ring. The handwheel housing is fixedly mounted on the handwheel guide seat. It utilizes a wheel guide seat that can move axially relative to the spline sleeve and a handwheel positioning ring fixed to the temperature control valve core to cooperate. Pulling the wheel guide seat backward moves it to offset the first stop of the handwheel positioning ring, thereby allowing the handwheel to be turned to adjust the high temperature range; however, its adjustment structure is relatively complex and significantly changes the internal structure of the handwheel. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a water heating temperature control valve handwheel with a sound function. Without changing the handwheel shell, this temperature control valve handwheel only adds a gear slot and a sound-producing element inside the handwheel, so that the user can have a clear gear feel when rotating the handwheel, and at the same time emits a metallic knocking sound, and the internal structure of the handwheel is only slightly modified.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A handwheel for a water heating temperature control valve with a sound function includes a handwheel and a valve core seat installed inside the handwheel. The inner wall of the handwheel is provided with a gear groove. A threaded tube extends from the valve core seat toward the handwheel. A stop is provided at the connection between the valve core seat and the threaded tube. A sound-producing element that mates with the gear groove is sleeved on the threaded tube. A fastening nut is threadedly connected to the threaded tube for fastening the sound-producing element.

[0006] Preferably, the sound-producing element includes an annular portion sleeved on a threaded tube and a lever, the lever being connected to the annular portion and extending into a gear slot.

[0007] Preferably, the fastening nut has a notch on the side facing the lever to ensure that the lever extends out from the notch.

[0008] Preferably, the gear slots are arranged around the inner wall of the handwheel, adjacent gear slots are connected by a connecting wall, and the distance between adjacent gear slots is equal, so as to continuously sound the handwheel rotation status.

[0009] Preferably, the gear slot is V-shaped on the side.

[0010] Preferably, the gear slot is laterally arc-shaped.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The temperature control valve handwheel of this utility model, without changing the handwheel housing, only adds a gear slot and a sound-producing element inside the handwheel, so that the user can have a clear gear feel when rotating the handwheel, and at the same time emits a metallic knocking sound, and the internal structure of the handwheel is only slightly modified.

[0019] Example 1: A preferred embodiment of this utility model provides a water heating temperature control valve handwheel with a sound function, including a handwheel 1 and a valve core seat 2 installed in the handwheel 1. The inner wall of the handwheel 1 is provided with a stop groove 11. The valve core seat 2 extends a threaded tube 21 towards the handwheel 1. A stop 22 is provided at the connection between the valve core seat 2 and the threaded tube 21. A sound-producing element 3 that cooperates with the stop groove 11 is sleeved on the threaded tube 21. A fastening nut 4 is threadedly connected to the threaded tube 21 for fastening the sound-producing element 3.

[0020] The sound-producing element 3 includes an annular portion 31 sleeved on the threaded tube 21 and a lever 32. The lever 32 is connected to the annular portion 31 and extends into the gear slot 11.

[0021] The fastening nut 4 has a notch 41 on the side facing the lever 32 to ensure that the lever 32 extends out from the notch 41.

[0022] The gear slot 11 is arranged around the inner wall of the handwheel 1. Adjacent gear slots 11 are connected by a connecting wall 12, and the distance between adjacent gear slots 11 is equal, so as to continuously sound to indicate the rotation status of the handwheel 1.

[0023] Without altering the handwheel housing, this temperature control valve handwheel only adds a gear slot and a sound-producing element inside, allowing the user to feel a distinct gear position when rotating the handwheel, while also producing a metallic knocking sound, and the internal structure of the handwheel is minimally modified.

[0024] Example 2: A preferred embodiment of this utility model provides a water heating temperature control valve handwheel with a sound function, which differs from the above embodiment only in that the gear slot 11 is V-shaped on the side.

[0025] Example 3: A preferred embodiment of this utility model provides a handwheel for a water heating temperature control valve with a sound function. The only difference between this embodiment and the one described above is that the gear slot 11 is laterally arc-shaped.
