Description

Technical Field

[0001] This utility model relates to the field of bathroom fixtures, and more specifically, it relates to a faucet that prevents accidental activation. Background Technology

[0002] A faucet is a common name for a water valve, used to control the flow of water and thus save water. A typical temperature-controlled faucet includes a housing, handle, ceramic valve core, and push rod. The ceramic valve core is installed inside the housing and connected to the hot and cold water pipes and the outlet. The handle is mounted on the housing and connected to the ceramic valve core via the push rod. A rotating sleeve is located inside the housing, fitted over the push rod, and connected to the push rod via a positioning rod. This positioning rod acts as a fulcrum for the push rod; when the handle is lifted, the push rod rotates, opening the ceramic valve core.

[0003] When people wash their hair at the sink, they need to adjust the water temperature to a suitable level before pre-washing and then applying shampoo. During the shampooing process, people usually turn off the tap to stop the water flow to reduce water waste, and then turn the tap back on to rinse after the shampoo has lathered up.

[0004] However, when people turn the tap back on, their heads are covered in shampoo foam, so they may not be able to open their eyes to turn it on. They usually just touch the handle with their hands to turn it on, which can lead to accidental tap activation. This causes the tap to be turned off, resulting in different water temperatures. People then have to readjust the water temperature, which is inconvenient and wastes water resources. This is especially true for the elderly, as the stimulation from excessively high or low water temperatures is more noticeable.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a faucet that prevents accidental activation in order to solve the above-mentioned problems.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a faucet to prevent accidental activation, comprising a housing and a rotating sleeve disposed within the housing, wherein a limiting component is fixedly disposed on the housing to limit the rotation angle of the rotating sleeve, the limiting component comprising: A limiting member is used to abut against the rotating sleeve, and the limiting member is slidably disposed on the housing. A pushing component for pushing the limiting member to move, the pushing component being slidably disposed on the housing and having one end extending to the outside of the housing; When it is necessary to fix the rotation angle of the rotating sleeve, the limiting member is pushed by the pushing component to abut against the rotating sleeve, thereby fixing the position.

[0008] The present invention is further configured such that the pushing component includes: A sliding member is slidably disposed on the housing, and a hinge rod is hingedly connected between the sliding member and the limiting member. One end of the sliding member extends to the outside of the housing. An elastic element is used to push the sliding element to move away from the limiting element, and the two ends of the elastic element abut against the housing and the sliding element, respectively. By driving the slider to displace, a thrust is generated through the hinge rod to move the limiting member toward the rotating sleeve.

[0009] The present invention is further configured such that the pushing component also includes: A protective shell is embedded inside the housing, and the extension end of the sliding member is located inside the protective shell; A rotating component is rotatably mounted on a protective shell. The sliding component has an embedded guide groove, and the rotating component has a guide part that can be inserted into the embedded guide groove. So that when the rotating part is turned, the guide part can be inserted into the embedded guide groove to push the sliding part to move.

[0010] The present invention is further configured such that the embedded guide groove is an arc-shaped structure, and the first end of the embedded guide groove is located on the side of the end position close to the limiting member.

[0011] The present invention is further configured such that: the end of the embedded guide groove is connected to a positioning groove for engaging the position of the guide part, and the positioning groove is a transverse groove along the moving direction of the sliding member; When the guide moves to the positioning groove, the slider moves away from the limiting member so that the guide is embedded in the positioning groove.

[0012] The present invention is further configured such that the connection between the positioning groove and the embedded guide groove is provided with a rounded corner structure.

[0013] The present invention is further configured such that: the contact surfaces of the rotating sleeve and the limiting member are provided with toothed layers, and the toothed layers are slidably connected to the limiting member, with the sliding direction being consistent with the sliding direction of the limiting member; and an elastic interlayer is also provided between the toothed layers and the limiting member.

[0014] The present invention is further configured such that the sliding connection between the housing and the limiting member is a dovetail groove mechanism.

[0015] Compared with the prior art, the beneficial effects of this utility model are: Firstly, the limiting component ensures that when the faucet is turned on again after being turned off, the angle of the rotating sleeve is consistent with the previous angle by limiting the rotation angle of the rotating sleeve, thus avoiding the water temperature from being too hot or too cold due to angle deviation, and improving the user's comfort and safety. Secondly, by turning the rotating part, the sliding part can be easily pushed to drive the limiting part to abut the rotating sleeve by utilizing the cooperation between the arc-shaped embedded guide groove and the guide part; after the external force is removed, the elastic part automatically pushes the sliding part to reset and release the restriction. The operation process is simple and requires no additional power. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the present utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model. Example

[0019] A type of faucet that prevents accidental activation, such as Figures 1-2 As shown, it includes a housing 1 and a rotating sleeve 2 disposed inside the housing 1. A limiting component is fixedly disposed on the housing 1 to limit the rotation angle of the rotating sleeve 2. After the water temperature is adjusted, the faucet is closed, and the rotation of the rotating sleeve 2 is limited, so that when the faucet is turned on later, the opening angle is consistent with the previous opening angle, ensuring the stability of the water temperature, avoiding the occurrence of water temperature being too hot or too cold, and improving the user experience.

[0020] The limiting assembly includes a limiting member 3 for abutting against the rotating sleeve 2 and a pushing assembly for displacing the limiting member 3. Both the limiting member 3 and the pushing assembly are slidably mounted on the housing 1. The housing 1 and the limiting member 3 are slidably connected by a dovetail mechanism, which limits the sliding direction of the limiting member 3 and ensures the transmission stability of the structure. Furthermore, one end of the pushing assembly extends to the outside of the housing 1. Therefore, when it is necessary to fix the rotation angle of the rotating sleeve 2, applying external force to the outer end of the pushing assembly pushes the limiting member 3 against the rotating sleeve 2, thus fixing the position of the rotating sleeve 2.

[0021] A protective sleeve is rotatably installed inside the housing 1, and the protective sleeve is fitted over the outside of the rotating sleeve 2. The protective sleeve rotates synchronously with the rotating sleeve 2, which reduces the wear of the rotating sleeve 2. At the same time, the horizontal height of the rotating sleeve 2 is higher than that of the protective sleeve, thereby ensuring that the limiting member 3 and the rotating sleeve 2 are properly abutted and fixed.

[0022] The pushing assembly includes a slider 4 slidably mounted on the housing 1. A hinge rod 5 is hinged between the slider 4 and the limiting member 3. One end of the slider 4 extends to the outside of the housing 1. By pushing the extended end of the slider 4 inward, the limiting member 3 is moved downward and abuts against the rotating sleeve 2 to form a fixed effect. The pushing assembly also includes an elastic member 6 for pushing the slider 4 away from the limiting member 3. The two ends of the elastic member 6 abut against the housing 1 and the slider 4 respectively. When the slider 4 moves inward, it compresses the elastic member 6. When the external force on the slider 4 is removed, the elastic member 6 releases its elastic thrust, pushing the slider 4 back to its original position, which in turn causes the limiting member 3 to also return to its original position, releasing the fixation of the rotating sleeve 2.

[0023] The pushing assembly also includes a protective shell 7 embedded inside the housing 1 and a rotating member 8 rotatably disposed on the protective shell 7. The extended end of the sliding member 4 is located inside the protective shell 7 and can slide inside the protective shell 7. The protective shell 7 serves to protect the internal structure of the pushing assembly. At the same time, the sliding member 4 is provided with an embedded guide groove 9, and the rotating member 8 is provided with a guide part 10 that can be inserted into the embedded guide groove 9. So that when the rotating member 8 is rotated, it can be inserted into the embedded guide groove 9 through the guide part 10 to push the sliding member 4 to move.

[0024] The embedded guide groove 9 is set as an arc structure, and the first end of the embedded guide groove 9 is located on the side of the end position close to the limiting member 3, so that when the guide part 10 moves from the first end position to the end position, it will push the slider 4 to move closer to the limiting member 3.

[0025] The guide part 10 is configured as a cylindrical pin and is rotatably connected to the rotating part 8, so that the pin slides along the inner wall of the embedded guide groove 9, reducing the frictional resistance formed during transmission and improving the transmission efficiency.

[0026] The end of the embedded guide groove 9 is connected to the positioning groove 11, so that when the guide part 10 moves to the positioning groove 11, the contact between the guide part 10 and the side wall of the embedded guide groove 9 disappears, and the elastic member 6 releases the elastic thrust to push the sliding member 4 to move outward away from the restrictor 3, so that the guide part 10 is embedded in the positioning groove 11. The positioning groove 11 is a transverse groove along the moving direction of the sliding member 4. When the guide part 10 is embedded in the positioning groove 11, the rotation direction of the rotating member 8 is restricted by the side wall of the positioning groove 11, thereby fixing the position of the sliding member 4.

[0027] This allows the sliding member 4 to move inward, causing the hinge rod 5 to push the limiting member 3 downward to abut against the rotating sleeve 2; and the limiting member 3 to slide upward within the dovetail groove to release the abutment when it moves outward.

[0028] Furthermore, the connection between the positioning groove 11 and the embedded guide groove 9 is set with a rounded corner structure, so that when the rotating part 8 rotates in the opposite direction, it will drive the guide part 10 out of the positioning groove 11.

[0029] The rotating sleeve 2 and the limiting member 3 both have toothed layers 12 on their contact surfaces. The toothed layers 12 increase the frictional resistance when the rotating sleeve 2 and the limiting member 3 abut against each other, thus improving the stability of the positioning. At the same time, the rotating sleeve 2 is fixedly connected to the toothed layer 12, and the toothed layer 12 is slidably connected to the limiting member 3. The sliding direction is the same as that of the limiting member 3. An elastic interlayer 13 is also provided between the toothed layer 12 and the limiting member 3. The elastic support formed by the elastic interlayer 13 is used to achieve relative fixation between the toothed layer 12 and the limiting member 3, ensuring synchronous operation during normal movement.

[0030] When the guide part 10 moves to the end of the embedded guide groove 9, the distance between the limiting member 3 and the toothed layer 12 is less than the initial thickness of the elastic interlayer 13, so that the elastic interlayer 13 is in a compressed state. Thus, when the guide part 10 is embedded in the positioning groove 11, the elastic interlayer 13 and the elastic member 6 will synchronously form an elastic thrust, pushing the position of the sliding member 4 to form a small outward movement tendency, so that the guide part 10 is stably embedded in the positioning groove 11, ensuring the connection is firm.

[0031] Working principle: After adjusting the water temperature, turn off the faucet. Then, by rotating the rotating part 8, push the sliding part 4 towards the limiting part 3. The rotating part 8 is inserted into the embedded guide groove 9 through the guide part 10 and abuts against the side wall of the embedded guide groove 9, thereby achieving the effect of pushing the sliding part 4 to move. At the same time, when the guide part 10 slides along the guiding direction of the embedded guide groove 9 to the positioning groove 11, the thrust formed by the guide part 10 abutting against the side wall of the embedded guide groove 9 disappears. The elastic part 6 pushes the sliding part 4 outward a small distance, and then the guide part 10 is embedded in the positioning groove 11, thus fixing its position. Then, the sliding part 4 pushes the limiting part 3 against the rotating sleeve 2 through the hinge rod 5, thereby fixing the position of the rotating sleeve 2.

[0032] When it is necessary to release the fixed position, the rotating part 8 is reversed so that it exits the positioning groove 11 and returns to its original position along the embedded guide groove 9, thereby releasing the restriction.
