Description

Technical Field

[0001] The present application relates to the field of faucets, and in particular to a valve core clamping sealing structure and a faucet. Background Art

[0002] In faucet design and manufacturing, the valve core housing is a key component for controlling water flow. Its structure and durability are directly related to the faucet's overall performance and service life. Traditional faucet valve core housing designs often focus on sealing and fluid control efficiency, but are significantly deficient in resisting external mechanical stress, particularly rotational impact forces. In actual use, users turn the handle to open or close the faucet, generating a certain amount of torque and impact force that directly acts on the edges of the valve core housing.

[0003] A common problem has long been that the edges of the valve core housing, due to structural characteristics and material limitations, often have weak rotational resistance. This makes the edges prone to deformation, cracking, and even breaking. This not only affects the normal use of the faucet but can also cause leaks, increasing repair costs and wasting water. Furthermore, frequent repairs and replacements are inconvenient for users and reduce the user experience. Utility Model Content

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0035] During the screwing process of the existing valve core, the connection between the valve core shell and the base is very easy to break, which leads to water leakage and affects the normal time of the faucet. For this reason, the present application sets a stopper 300 on the shell 100 and a stop groove 400 on the base 200. During the connection process of the shell 100 and the base 200, the stopper 300 can be placed in the stop groove 400, so that the stopper 300 and the stop groove 400 are always in contact. The shell 100 and the base 200 mainly bear the rotational force, and then when the shell 100 rotates, the rotational force can be transmitted to the base 200, thereby preventing the snap structure 500 connecting the shell 100 and the base 200 from breaking.

[0036] Specifically, the present application provides a valve core clamping sealing structure, including a housing 100 , a base 200 , a stopper 300 , a clamping structure 500 and a sealing member 600 .

[0037] The stop block 300 is arranged at the end of the shell 100 close to the base 200, and a stop groove 400 adapted to the stop block 300 is opened on the base 200. The stop block 300 can penetrate into the stop groove 400. The snap structure 500 is used for the detachable installation of the shell 100 and the base 200. The seal 600 is arranged between the inner wall of the shell 100 and the outer surface of the base 200.

[0038] See Figure 1 and Figure 2As shown, the valve core includes a shell 100 and a base 200, wherein the shell 100 and the base 200 are clamped together by a snap-fit ​​structure 500, thereby achieving limitation in the axial direction and the radial direction. When the shell 100 rotates, the power is transmitted to the base 200 through the snap-fit ​​structure 500, thereby driving the base 200 to rotate. However, when the rotational force from the shell 100 is too large, it is easy to break the snap-fit ​​structure 500 and separate the shell 100 from the base 200. For this reason, the present application cooperates with the block 300 and the retaining groove 400 at the connection between the shell 100 and the base 200, so that a larger rotational force can be transmitted to the base 200, thereby preventing the snap-fit ​​structure 500 from breaking.

[0039] Furthermore, in order to improve the sealing between the housing 100 and the base 200 , a sealing member 600 is provided between the inner wall of the housing 100 and the outer surface of the base 200 to ensure the sealing between the housing 100 and the base 200 .

[0040] In this embodiment, the seal 600 is a sealing ring. For example, the sealing ring can be an O-ring, a V-ring, a rectangular sealing ring, etc. In practice, it can be selected according to factors such as the working environment. The specific type is not limited here.

[0041] Exemplarily, the stop block 300 is arranged on the end face of the shell 100 facing the base 200, and the stop block 300 and the shell 100 are integrally formed, the stop groove 400 is opened on the frame of the outer surface of the base 200, and the stop groove 400 and the base 200 are integrally formed; or the stop block 300 is set on the frame of the base 200, the stop groove 400 is opened on the end face of the shell 100, the stop groove 400 and the shell 100 are integrally formed, and the stop block 300 and the base 200 are integrally formed; in this embodiment, the stop block 300 is selected to be set on the shell 100, and the stop groove 400 is set on the base 200.

[0042] The cross section of the blocking block 300 gradually decreases along the first preset direction, and the cross section of the blocking groove 400 gradually increases along the first preset direction.

[0043] See Figure 2 As shown, in order to keep the stopper 300 and the stop groove 400 in contact with each other, when subjected to the impact force of rotation, the force from the housing 100 can be transmitted to the base 200 in a timely and rapid manner.

[0044] Specifically, the first preset direction mentioned above is the axial direction of the shell 100, that is, the height direction of the shell 100. In this embodiment, the shell 100 can be set to be located above the base 200. Then, in the height direction, the horizontal cross-section of the retaining groove 400 gradually increases from top to bottom. Correspondingly, in order to enable the stop block 300 to always contact the inner wall of the retaining groove 400, the horizontal cross-section of the stop block 300 gradually decreases from top to bottom. For this reason, the stop block 300 can be engaged with the retaining groove 400 to limit the rotation direction of the shell 100 and the base 200, and the rotational force from the shell 100 can be transmitted to the base 200 through the cooperation of the stop block 300 and the retaining groove 400, so that the shell 100 and the base 200 rotate synchronously.

[0045] For example, the cross-section of the stopper 300 may be a quadrilateral, a circle, or the like. Accordingly, the shape of the stopper groove 400 is adapted to the stopper 300 . In this embodiment, the cross-section of the stopper 300 is a quadrilateral.

[0046] The angle α between the center line of the retaining groove 400 and the tangent line of the outer circumference of the base 200 satisfies the following: 30°≤α≤60°.

[0047] See Figure 2 and Figure 4 As shown, the center line of the retaining groove 400 and the tangent of the outer circumference of the base 200 form an angle of a certain angle, and the angle α can take any value between 30° and 60°, mainly to better transfer the force from the shell 100 to the base 200. For example, the angle α can take a value of 30°, 40°, 50°, 60°, etc. In practice, it can be selected and used according to needs, and is not limited here.

[0048] The number of the blocking blocks 300 is the same as the number of the blocking grooves 400 . There are N blocking blocks 300 , and N≧1.

[0049] Please continue reading Figure 1 、 Figure 3 as well as Figure 4 As shown, each stop block 300 and the stop groove 400 are matched as a group, that is, the number of stop blocks 300 and the number of stop grooves 400 are the same, of which there are N groups in total, satisfying N≥1. When there is 1 group, the positions of the stop blocks 300 and the stop grooves 400 are not limited, and can be set as needed under the premise of meeting the matching requirements. In this embodiment, the axis of the shell 100 and the axis of the base 200 are located on the same straight line. When N≥2, that is, when the number of groups is greater than or equal to 2, the multiple groups of stop blocks 300 and stop grooves 400 are evenly spaced about the axis of the shell 100 and the base 200.

[0050] The snap-fit ​​structure 500 includes a connecting block 510 arranged at the end of the shell 100 close to the base 200, a card slot 520 is opened in the connecting block 510, an avoidance groove 530 is opened on the base 200, and a card block 540 is set on the inner wall of the avoidance groove 530, and the card block 540 can be snapped into the inside of the card slot 520.

[0051] See Figure 1 、 Figure 2 as well as Figure 3 As shown, an avoidance groove 530 is provided on the base 200, and a card block 540 is integrally formed on the inner wall of the avoidance groove 530 facing the center of the base 200. A connecting block 510 is integrally formed at the end of the shell 100 facing the base 200, and a card slot 520 is provided on the connecting block 510. During the installation process of the shell 100 and the base 200, the shell 100 moves toward the base 200. When the card block 540 contacts the connecting block 510, the connecting block 510 will undergo a certain deformation. As the shell 100 continues to move, the card block 540 will be stuck in the card slot 520. At this time, the connecting block 510 will return to its original shape due to its own elasticity, completing the installation of the shell 100 and the base 200.

[0052] It should be noted that, when the locking block 540 is locked into the locking slot 520 , the blocking block 300 will also enter the blocking slot 400 .

[0053] Exemplarily, the snap-fit ​​structures 500 have at least two groups, and are evenly spaced about the central axis of the base 200. Of course, the snap-fit ​​structures 500 can also be other numbers according to actual needs, and the specific number is not limited here. In this embodiment, the snap-fit ​​structures 500 have two groups, and the two groups of snap-fit ​​structures 500 are symmetrically distributed.

[0054] A through slot 550 is formed on the inner wall of the latch slot 520 facing the base 200 .

[0055] Please continue reading Figure 2 and Figure 5 As shown, in order to enable the card block 540 to enter the card slot 520 more smoothly and be snapped in, a through groove 550 is opened through the inner wall of the card slot 520. When the connecting block 510 contacts the card block 540, the connecting block 510 is more likely to deform toward the outside, thereby making it easier for the card block 540 to enter the card slot 520 and be snapped in.

[0056] See Figure 2 and Figure 3As shown, the block 540 is provided with an inclined guide surface (not marked in the figure); further, in order to enable the block 540 to be inserted into the slot 520, an inclined guide surface is provided at the contact position between the block 540 and the connecting block 510 during the process of the block 540 entering the slot 520, and the block 540 is guided by the inclined guide surface so that the block 540 can smoothly enter the slot 520 and be engaged.

[0057] Please continue reading Figure 5 As shown, in the process of the card block 540 entering the card slot 520, an inclined guide surface is also provided at the position where the connecting block 510 contacts the card block 540. Through the cooperation of the two inclined guide surfaces, the card block 540 and the card slot 520 are more easily connected, which reduces the difficulty of installation and improves efficiency.

[0058] The base 200 has an outer surface formed with a receiving groove 700 , and the sealing member 600 is installed in the receiving groove 700 .

[0059] Continue reading Figure 2 and Figure 3 As shown, during the process of snap-connecting the housing 100 and the base 200, in order to prevent the seal 600 from changing position, a receiving groove 700 is opened on the outer surface of the base 200, and the seal 600 is installed in the receiving groove 700. Since the seal 600 has the receiving groove 700 to limit its position, the position of the seal 600 will not change during installation.

[0060] A plurality of limiting structures 800 are further provided between the housing 100 and the base 200 . The limiting structures 800 include positioning members 810 provided on the housing 100 , and positioning grooves 820 adapted to the positioning members 810 are provided on the base 200 .

[0061] according to Figures 2 to 5 As shown, in order to further improve the clamping strength between the shell 100 and the base 200 in the rotational direction, a positioning member 810 is provided on the shell 100, and a positioning groove 820 is opened on the base 200. When the shell 100 and the base 200 are clamped by the snap structure 500, the positioning member 810 will simultaneously enter the positioning groove 820 to realize the clamping positioning in the rotational direction.

[0062] The present application also provides a faucet, comprising the valve core clamping sealing structure described in any one of the above items.
