Description

Technical Field

[0001] The utility model relates to the technical field of faucets, in particular to a heat-resistant faucet. Background Art

[0002] At present, a Chinese patent with announcement number CN217382190U discloses a heat-resistant bathroom faucet, and its technical solution is mainly used to solve the problem that people are scalded by hot water due to carelessness when turning on the faucet. The heat-resistant logic of the patent has two ideas: one is to drive the first water baffle plate to approach or move away from the first water blocking ring by rotating the threaded rod, and thereby control the opening and closing of the hot water pipe; the other is to use the impact force of cold water to make the second water baffle plate in the one-way flow guide device close to the second water blocking ring to block the hot water flow.

[0003] However, there are two inconveniences under these two logics: First, when the first water baffle is kept away from the first water blocking ring, if the user wants to achieve the heat-blocking effect, the cold water must be greater than a certain flow rate so that the second water baffle can block the hot water. However, in daily life, this method cannot meet people's needs for frequent changes in water flow size; second, if the flow of hot water is reduced or closed by turning the screw to solve the above problem, the threaded rod will go back and forth between the inside and outside of the protective shell when it rotates, and this phenomenon will cause bacteria or external impurities to enter the pipe during long-term use, so it is not very hygienic.

DETAILED DESCRIPTION

[0023] The following will be combined with the attached embodiment of the utility model Figure 1-4 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example:

[0025] like Figures 1 to 4 As shown, the utility model discloses a heat-resistant faucet, comprising a mounting base 1 and a water outlet pipe 2. The mounting base 1 is provided with a switch handle 3, a handle stopper 4 and a displacement mechanism, wherein the switch handle 3 is hinged on the mounting base 1, and when the faucet discharges water, people can adjust the water flow and temperature by turning the switch handle 3, and the functions of the handle stopper 4 and the displacement mechanism are: the displacement mechanism can move the handle stopper 4 to the rotation path of the switch handle 3, so that the handle stopper 4 can be used to abut against the switch handle 3, so that the rotation range of the switch handle 3 is limited, thereby forming a heat-resistant function.

[0026] Specifically:

[0027] An annular ring 41 is fixedly provided on the end of one end of the handle stopper 4, and the annular ring 41 is sleeved outside the mounting seat 1 and rotatably connected to the mounting seat 1. At the same time, a first slide groove 42 is provided on the inner side wall of the annular ring 41, and the first slide groove 42 extends to the inside of the handle stopper 4; a plurality of slots 11 are provided on the outer side wall of the mounting seat 1 along the circumferential direction; the displacement mechanism includes a plug-in 51, one end of which is slidably arranged in the first slide groove 42, and the other end of the plug-in 51 is used to slide out of the first slide groove 42 and insert into the slot 11, so that the position of the handle stopper 4 on the mounting seat 1 is fixed. In addition, the displacement mechanism also includes an elastic supporting member 52 for pushing the plug-in 51 out of the first slide groove 42 and a linkage rod 53 for bringing the plug-in 51 back into the first slide groove 42.

[0028] When the first slide groove 42 is opposite to the slot 11, the plug-in 51 can be inserted into the slot 11 under the action of the elastic abutment 52, and the position of the handle stopper 4 can be fixed. It should be noted that the position of at least one slot 11 needs to be set such that when the plug-in 51 is inserted into the slot 11, the handle stopper 4 is exactly on the rotation path of the switch handle 3, and the position where the handle stopper 4 abuts against the closing handle can prevent the switch handle 3 from turning on the hot water. When the faucet needs to be heat-blocked, the plug-in 51 only needs to be inserted into the slot 11.

[0029] The elastic resisting member 52 is disposed in the first sliding groove 42 and is located at a side of the plug-in unit 51 away from the annular ring 41 . The elastic resisting member 52 may be a spring.

[0030] A second slide groove 43 is provided inside the handle stopper 4, one end of which extends outward to penetrate the free end of the handle stopper 4, and the other end is connected to the first slide groove 42. In this structure, the linkage rod 53 is slidably arranged in the second slide groove 43, and its sliding direction is the same as the sliding direction of the plug-in 51. At the same time, one end of the linkage rod 53 is rotatably connected to the plug-in 51, and the other end extends to pass through the second slide groove 43. In addition, a protrusion 531 is fixedly provided on the side wall of the linkage rod 53, and a third slide groove 44 and a rotating groove 45 are provided on the inner side wall of the second slide groove 43, respectively used for the protrusion 531 to slide and rotate, wherein the rotating groove 45 is located at one end of the third slide groove 44 away from the annular ring 41, and an embedded groove 46 is provided on the side wall of the rotating groove 45 close to the annular ring 41, and the cross section of the embedded groove 46 coincides with the cross section of the protrusion 531. In this structure, the cross sections of the linkage rod 53 and the second slide groove 43 are both circular.

[0031] A swing arm 532 is fixedly provided on the end of the linkage rod 53 passing through the second sliding groove 43 , and an “L”-shaped structure is formed between the swing arm 532 and the linkage rod 53 .

[0032] The working principle of the above structure is as follows: when the linkage rod 53 is pulled backward, the linkage rod 53 can drive the plug-in 51 to exit the slot 11. At this time, the handle block 4 can be rotated at will. People can decide which slot 11 to insert the plug-in 51 into according to whether heat resistance is needed or the maximum temperature range expected for water discharge from the faucet. After the handle block 4 moves to the ideal position, the linkage rod 53 is released, and the elastic supporting member 52 can push the plug-in 51 back into the slot 11, so that the position of the handle block 4 is fixed, thereby limiting the rotation range of the switch handle 3.

[0033] If people do not need the handle block 4 to restrict the switch handle 3, they can also pull the linkage rod 53 backward until the protrusion 531 on the linkage rod 53 enters the rotation groove 45, and then rotate the protrusion 531 to the position of the embedding groove 46, and then release the linkage rod 53. At this time, since the position of the linkage rod 53 is limited, the elastic pushing member can no longer push the plug-in 51 into the slot 11, so the handle block 4 can be rotated at will. When the handle block 4 hits the switch handle 3, the handle block 4 can be directly pushed open by hand.

[0034] It should also be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
