Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0015] Appendix Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0016] 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.

[0017] The present invention will now be further described with reference to the accompanying drawings.

[0018] This utility model provides the following technical solution:

[0019] As attached Figure 1 As shown, this utility model discloses a ball bearing faucet, including a valve body 1, a handwheel 2, and a ball bearing mounting base 3. The ball bearing mounting base 3 is detachably mounted on the valve body 1. The ball bearing mounting base 3 has a valve body connecting part 4, a valve body positioning part 5, and a ball bearing mounting part 6. The valve body connecting part 4 extends into the valve body 1 and connects to the valve body 1. A sealing and limiting annular groove 7 is formed between the valve body positioning part 5 and the valve body connecting part 4. The sealing and limiting annular groove 7 has a sealing part 8 and a limiting part 9. The limiting part 9 is located on the upper part of the sealing part 8 away from the central axis of the ball bearing mounting base 3. The top end of the valve body 1 extends into the limiting part 9 and is limited to contact with the ball bearing mounting base 3. A sealing ring 10 is provided inside the sealing part 8, and the sealing ring 10 is pressed against one side of the top end of the valve body 1. Specifically, in this design, by forming a sealing and limiting annular groove 7 on the ball bearing mounting base 3, the connection between the valve body 1 and the ball bearing mounting base 3 is made tighter, effectively preventing water leakage from the connection point. Meanwhile, the limiting part 9 ensures that the valve body 1 can be accurately aligned and fixed on the ball bearing mounting seat 3 during assembly, improving assembly accuracy and efficiency. Furthermore, the sealing ring 10 within the sealing part 8 further enhances the sealing performance of the connection, maintaining good waterproofing even under prolonged use or water pressure variations.

[0020] Furthermore, the limiting part 9 is recessed on the bottom end face of the valve body positioning part 5, and the sealing part 8 is recessed on the side of the valve body connecting part 4 near the valve body positioning part 5. The extension line of the limiting part 9 intersects with the extension line of the sealing part 8 to form an L-shaped groove structure. Specifically, in this embodiment, this L-shaped groove structure design of the limiting part 9 and the sealing part 8 further enhances the connection stability and sealing performance between the valve body 1 and the ball bearing mounting seat 3. The recessed design of the limiting part 9 makes it easier for the top of the valve body 1 to slide into and be locked in the limiting part 9 during assembly, effectively preventing the valve body 1 from loosening or shifting due to water pressure or external force during use. At the same time, the recessed design of the sealing part 8, in conjunction with the use of the sealing ring 10, forms a more robust waterproof barrier, further improving the waterproof performance of the faucet. In addition, the L-shaped groove structure also makes the connection between the valve body 1 and the ball bearing mounting seat 3 tighter, reducing gaps at the connection and thus reducing the risk of water leakage.

[0021] Furthermore, an inner sealing sleeve 11 is provided on the inner wall of the valve body 1 near the ball bearing mounting seat 3. The inner sealing sleeve 11 has an annular structure and is fixed to the inner wall of the valve body 1. The inner and outer annular sides of the inner sealing sleeve 11 are respectively sealed to the valve body connecting part 4 and the inner wall of the valve body 1. The inner sealing sleeve 11 is made of rubber. Specifically, in this embodiment, the inner sealing sleeve 11 further enhances the sealing effect between the valve body 1 and the ball bearing mounting seat 3. Its annular structure can tightly fit the inner wall of the valve body 1, ensuring that water flow will not leak out through the tiny gaps between the valve body 1 and the ball bearing mounting seat 3. At the same time, the choice of rubber material gives the inner sealing sleeve 11 good elasticity and wear resistance, enabling it to adapt to working environments under different water pressures and maintain stable sealing performance over a long period of time. The inner sealing sleeve 11 is fixed to the inner wall of the valve body 1 by adhesive, making installation simple and reliable.

[0022] Furthermore, the ball bearing mounting part 6 consists of three arc-shaped grooves formed at the top of the ball bearing mounting base 3. Each arc-shaped groove contains a ball bearing body 12. A corresponding handwheel positioning groove 13 is formed on the side of the handwheel 2 closest to the ball bearing mounting base 3. The upper and lower parts of the ball bearing body 12 extend into the handwheel positioning groove 13 and the arc-shaped groove, respectively, connecting with the handwheel 2 and the ball bearing mounting base 3. Specifically, in this embodiment, when in use, rotating the handwheel 2 causes the ball bearing body 12 on the handwheel 2 mounting base to move along the lower end face of the handwheel 2. After the ball bearing body 12 disengages from the arc-shaped groove, it contacts the lower end face of the handwheel 2, thus lifting the handwheel 2. As the handwheel 2 is lifted upwards, it pulls the valve stem and valve block upwards. The valve block disengages from the valve body flow channel 16, making the valve body flow channel 16 unobstructed. Water is then sprayed from the inlet 14 through the water inlet channel and out of the outlet 15. The user can then spray water directly from the outlet 15. Direct drinking water is possible; after releasing handwheel 2, the return spring pulls handwheel 2, causing the ball bearing body 12 to rotate. Because the surface of the ball bearing body 12 is very smooth, it automatically slides into the arc-shaped groove on the lower end face of handwheel 2, resetting handwheel 2. The valve stem and valve block move downwards, and the valve block enters the valve body flow channel 16, closing the flow channel and cutting off the water flow. This achieves automatic shut-off, making it suitable for various public places without wasting water. It is also convenient and hygienic to use.

[0023] Furthermore, the included angle between each of the ball bearing bodies 12 is 120°. Specifically, in this embodiment, this design makes the distribution of the three ball bearing bodies 12 on the ball bearing mounting base 3 more uniform. When the handwheel 2 rotates, each ball bearing body 12 can move smoothly along the lower end face of the handwheel 2, ensuring the smooth lifting and resetting of the handwheel 2. In addition, the 120° included angle design can also effectively prevent the ball bearing bodies 12 from interfering with each other or getting stuck during movement.

[0024] Furthermore, the valve body 1 has an inlet 14 and an outlet 15, and a valve body flow channel 16 is formed between the inlet 14 and the outlet 15. The valve body flow channel 16 is connected to the inlet 14 and the outlet 15 respectively. A drain outlet 17 is opened at the bottom of the valve body 1. The drain outlet 17 is connected to the valve body flow channel 16 and the outside of the valve body 1. A drain plug 18 is provided in the drain outlet 17. One end of the drain plug 18 extends into the valve body flow channel 16 near the outlet 15.

[0025] Furthermore, a through-hole is provided between the valve body flow channel 16 and the outlet 15, connecting the valve body flow channel 16 and the outlet 15. The drain plug 18 is screwed into the drain port 17, and screwing in or out the drain plug 18 adjusts the diameter of the through-hole between the outlet 15 and the valve body flow channel 16. Specifically, in this embodiment, when it is necessary to adjust the water flow rate, the user can rotate the drain plug 18 to change its position in the drain port 17, thereby adjusting the diameter of the through-hole. When the drain plug 18 is screwed into the drain port 17, the diameter of the through-hole gradually decreases, increasing the resistance of the water flow through the through-hole, thus reducing the water flow rate at the outlet 15; conversely, when the drain plug 18 is screwed out of the drain port 17, the diameter of the through-hole gradually increases, decreasing the resistance of the water flow through the through-hole, thus increasing the water flow rate at the outlet 15. This design allows users to easily adjust the water flow rate according to actual needs, improving the practicality and flexibility of the product.

[0026] Furthermore, a handwheel positioning ring groove 19 is formed at the top edge of the ball bearing mounting base 3. One end of the handwheel 2 extends into the handwheel positioning ring groove 19 and connects to the ball bearing mounting base 3. A ball bearing 20 is installed inside the handwheel positioning ring groove 19, and the ball bearing 20 is connected to both the groove wall of the handwheel positioning ring groove 19 and the handwheel 2. Specifically, in this embodiment, the handwheel 2 is rotatably connected to the ball bearing mounting base 3 through the ball bearing 20. This connection method makes the handwheel 2 rotate more smoothly and stably, reducing frictional resistance during rotation. By rotating the handwheel 2, the user can easily drive the drain plug 18 to move in a spiral motion within the drain outlet 17, thereby achieving precise adjustment of the outlet diameter.

[0027] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
