Description

Technical Field

[0001] This utility model relates to the field of bathroom fixtures technology, and in particular to a thermostatic handwheel with a constant pull switch mechanism. Background Technology

[0002] In the field of thermostatic handwheel technology, current mainstream solutions exhibit significant homogenization and functional limitations, specifically: The operation design and appearance are highly homogenized: the existing thermostatic handwheels on the market generally adopt a "button-type operation" design, which has become the industry standard and lacks differentiated innovation. The button needs to be integrated separately into the handwheel structure, resulting in a monotonous product appearance design and insufficient aesthetics. It fails to meet the current consumer demand for "simple and stylish" appearance of the equipment, and it is also difficult to adapt to the market trend of upgrading product aesthetics in home appliances, bathroom fixtures and other fields. The overall design lacks innovation.

[0003] Temperature control function has limitations: Traditional push-button thermostatic handwheels are limited by structural design and can only achieve control of a single temperature range. They cannot meet users' needs for high and low temperature segmented adjustment in different scenarios. The function coverage is narrow and it is difficult to match the diverse user needs.

[0004] Insufficient production assembly and product stability: The assembly process of push-button handwheels is complex, requiring separate installation of the button assembly, which adds extra production steps and increases the time and cost of manufacturing. Furthermore, problems such as assembly gaps and loose parts are prone to occur during the assembly of the button and handwheel, affecting not only the operating feel but also potentially leading to decreased temperature control accuracy, button malfunction, and other failures, thus reducing the overall stability and reliability of the product.

[0005] Based on the above-mentioned technical problems, this utility model provides a constant temperature handwheel with a constant pull switch method. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Reference Figures 1-6 This utility model provides a constant temperature handwheel with a constant pull switch, including a handwheel housing 1, a handwheel inner 2, a rear cover 3, a positioning component, and an elastic component; The inner inch 2 of the handwheel has a stepped rotating structure; The handwheel housing 1 is slidably fitted in the middle of the handwheel inner dimension 2; The rear cover 3 is threaded to one end of the inner inch 2 of the handwheel, which is located inside the handwheel housing 1, and slides with the handwheel housing 1. The elastic element is disposed between the rear cover 3 and the handwheel housing 1; The positioning component is installed on the inner dimension 2 of the handwheel, and a positioning groove is provided on the outer shell 1 of the handwheel, with the positioning groove and the positioning component having a limiting fit.

[0020] This constant-pull switch-type thermostatic handwheel achieves stable switching control and thermostatic function through the coordinated action of its components. The inner inch 2 of the handwheel adopts a stepped rotating structure, providing a precise installation reference and motion guide for the entire component. The outer shell 1 of the handwheel is slidably fitted in the middle of the inner inch 2, and can slide back and forth along the axis of the inner inch, serving as the direct contact component for user operation and transmitting the action of triggering the switch. The rear cover 3 is fixed to one end of the inner inch 2 inside the outer shell via a threaded connection, achieving reliable assembly between components and forming a sliding fit with the outer shell, providing a stable track for the outer shell's sliding. An elastic element is installed between the rear cover 3 and the outer shell. When the user pulls or pushes the outer shell, the elastic element will generate corresponding elastic deformation, forming a constant counterforce, ensuring uniform pull feedback throughout the operation and achieving the "constant pull" switching effect. Meanwhile, the positioning component is installed on the inner inch 2 of the handwheel, and the outer shell has a corresponding positioning groove. When the outer shell slides to a specific position, the positioning component and the positioning groove form a limiting fit, accurately locking the switch state and avoiding position displacement due to accidental contact, thus ensuring the accuracy of switch control. Moreover, the overall structure is adapted to the installation and operation requirements of the constant temperature system, achieving the switching function without affecting the constant temperature performance.

[0021] The design is further optimized so that the positioning component includes a positioning pin 5, which is threaded onto the inner dimension 2 of the handwheel and engages with the positioning groove for limiting.

[0022] The scheme is further optimized. The elastic element includes a spring 4, which is sleeved on the top of the inner part 2 of the handwheel, and the two ends of the spring 4 are fixed to the rear cover 3 and the outer shell 1 of the handwheel, respectively.

[0023] The design was further optimized so that the length of the locating pin 5 is 10mm-15mm.

[0024] The design was further optimized by installing a sealing ring between the outer periphery of the rear cover 3 and the handwheel housing 1.

[0025] A threaded rod is fixed at the center of the back cover 3, and a threaded hole is opened at the center of the top of the handwheel inner inch 2, with the threaded rod threaded into the threaded hole.
