Adjustable temperature limiting ring and temperature adjusting structure comprising same

Abstract

The invention provides an adjustable temperature limiting ring and a temperature adjusting structure comprising the same, and belongs to the technical field of constant-temperature faucets. The adjustable temperature limiting ring is provided with a normal temperature stop block and a high temperature stop block, wherein the normal temperature stop block is fixedly arranged on the adjustable temperature limiting ring, and the high temperature stop block is movably arranged on the adjustable temperature limiting ring. Specifically, the adjustable temperature limiting ring comprises a fixed temperature limiting outer ring and an adjustable temperature limiting inner ring, the high temperature stop block is arranged on the adjustable temperature limiting inner ring, the adjustable temperaturelimiting inner ring is installed in the fixed temperature limiting outer ring in a matched mode, and the adjustable temperature limiting inner ring is rotated to drive the high temperature stop blockto move. The adjustable temperature limiting ring provided by the invention can replace a traditional temperature limiting ring, and temperature limiting rings of different specifications do not needto be designed according to different temperature limiting requirements; and the adjustable temperature limiting inner ring of the adjustable temperature limiting ring can be rotated and rotated, thus, the position of the high temperature stop block can be adjusted, and the adjustable temperature limiting ring can be used for limiting the water outlet temperature with different requirements.

Description

technical field [0001] The invention belongs to the technical field of thermostatic faucets, and in particular relates to an adjustable temperature-limiting ring and a temperature-regulating structure containing the temperature-limiting ring. Background technique [0002] The thermostatic spool is a device that automatically adjusts the mixing ratio of cold and hot water so that the temperature of the mixed water can be kept at the set temperature automatically. It is widely used in the bathroom faucet industry. The thermostatic spool is installed in the main valve body of the faucet. The thermostatic handle at the end of the thermostatic spool is connected to the synchronous tooth groove in the thermostatic handwheel. Turn the thermostatic handwheel clockwise or counterclockwise to rotate the thermostatic handle synchronously. Thereby changing the state of the thermosensitive element in the thermostatic valve core to increase or decrease the water temperature when the water...

Problems solved by technology

[0005] However, the temperature limiting ring in the prior art still has the following problems: 1. There are no strict regulations on the limit water temperature of the faucet in the industry, and the limit temperature of the faucet selected by different manufacturers for different faucet products is not the same. Some are 42°C, some are 45°C or 49°C, etc., so the angle between the designed conventional limit block and the limit limit block is also inconsistent. Each angle design requires different molds for processing, which leads to Low mold utilization rate and high production cost

2. For the temperature limiting ring in the prior art, the conventional limit block, the limit limit block and the temperature limit ring are integrally formed. After the limit limit block is designed and manufactured, its position is fixed, that is to say, under the same design The angle between the conventional limit block and the limit limit block is the same; however, the problem is that the thermostatic spool assembled with the temperature limit ring, the thermostatic spool includes thermal elements, pistons, regulators, etc. There are multiple parts such as warm handles and handle gloves, and the thermostatic valve core is assembled from various parts. Each part itself has a tolerance due to the deviation of the manufacturing process. When many parts are combined, the actual temperature control effect of the thermostatic valve core is the same as that in theory There are not small deviations; for example, if the design limit outlet water temperature is 45°C, to change the outlet water temperature of the thermostatic valve core from 38°C to 45°C, assuming that the thermostatic valve core’s thermostat handle is rotated 90 degrees in theory, the limit The angle between the conventional limit block and the limit limit block in the temperature valve is correspondingly designed to be 90 degrees; however, due to the deviation of the thermostatic valve core itself, in order to achieve the water outlet effect of 45°C, it may actually need to be rotated by 92 degrees or only It needs to be rotated by 87 degrees, which is different from 90 degrees; when the temperature adjustment handle is rotated by 90 degrees, and the positioning pin on the temperature adjustment handwheel is in contact with the limit limit block, the actual water outlet temperature of the thermostatic valve core often does not reach 45 °C Or more than 45°C, the actual temperature limit effect is unstable. For customers with relatively high requirements, the deviation is relatively large. The faucet products including the thermostatic valve core and the temperature limit ring fail to pass the inspection, and the existing temperature limit ring cannot meet the requirements. Due to the demand in practical applications, the overall qualification rate of leading products is low, the production efficiency is not high, and resources are easy to waste
