Description

Technical Field

[0001] The utility model relates to the technical field of steam faucets, in particular to a steam faucet with smooth rotation. Background Art

[0002] A faucet, also known as a water valve, mainly functions to control the size of the water flow switch, including increasing / decreasing the water flow size and opening / closing the water flow. Currently, faucets are often used in household life. For example, household water heaters. A large amount of water vapor is generated when the faucet of a water heater discharges hot water, so it is also called a steam faucet. Of course, steam faucets are also used in other life or work scenarios.

[0003] The existing steam faucet places a universal ball inside a sealed cavity. To achieve sealing, a metal ball bowl and a spring are used to make the universal ball closely fit with the sealing rubber ring inside the cavity, thereby achieving the sealing effect. At the same time, in order to enable the metal ball bowl to fit the universal ball normally and also rotate normally, a large amount of lubricating grease needs to be applied between the metal ball bowl and the universal ball; and steam needs to pass through this sealed cavity and finally be discharged into the food solution, which means that the steam may carry lubricating grease and pose a food safety hazard. In addition, the spring, rubber ring, and ball bowl in the existing steam faucet will all show wear and aging due to high temperature and eventually become scrapped, resulting in steam leakage and posing a hazard to people. Therefore, a steam faucet that can ensure the normal rotation of the universal ball without coating lubricating grease is needed, so as to drive the pipeline for steam circulation to rotate smoothly and avoid contaminating food. Summary of the Utility Model

The cross-sections of the limit through hole 42 and the receiving cavity 8 are both circular. The limit through hole 42 penetrates through the upper end cover 4 along the thickness direction of the upper end cover 4, and the receiving cavity 8 penetrates through the lower end cover along the thickness direction of the lower end cover. The upper end cover 4 is fixedly or detachably fixed to the lower end cover. One end face of the upper end cover 4 is spaced parallel to the lower end cover. The center of the ball where the limit through hole 42 is located on the upper end cover 4 coincides with the center of the ball where the receiving cavity 8 is located on the lower end cover.

[0028] In an alternative embodiment, the cross-sections of the upper end cover 4 and the lower end cover are both circular. For example, both are circular plates with a certain thickness, and the diameters of the upper end cover 4 and the lower end cover are each greater than their respective thicknesses.

The diameter of the limit through hole 42 is also smaller than the maximum diameter of the universal ball 5. The diameter at the nearest end of the receiving cavity near the limit through hole 42 is greater than the maximum diameter of the universal ball 5.

[0030] When one end face of the upper end cover 4 is completely spaced parallel to one end face of the lower end face, the limit through hole 42 and the receiving cavity 8 together form an activity space that allows the universal ball 5 to rotate omnidirectionally (360°), and both ends of the universal ball 5 are respectively limited at the end parts of the limit through hole 42 and the end of the receiving cavity 8 away from the limit through hole 42.

The universal ball 5 is in open contact with the upper end cover 4, that is, the edge of the universal ball 5 is in open contact with the limit through hole 42. To achieve the open contact between the universal ball 5 and the upper end cover 4, after the upper end cover 4 and the lower end cover are spaced parallel to each other, the universal ball 5 can be completely squeezed and limited within the activity space, and the universal ball 5 is in open contact with the upper end cover 4.

[0032] The other end of the metal pipe 9 extends in the direction away from the lower end cover and is located outside the lower end cover.

[0033] In an alternative embodiment, one or more fixing holes 41 are provided on the upper end cap 4, and the fixing holes 41 penetrate through the upper end cap 4. The same number of mounting holes as the fixing holes 41 are provided on the lower end cap, one mounting hole corresponding to one fixing hole 41, and the fixing holes 41 and the mounting holes are on the same straight line. The upper end cap 4 and the lower end cap are fixedly or detachably connected together by a locking assembly. One end of the locking assembly passes through the mounting hole and extends into the fixing hole 41, and both ends of the locking assembly are located outside the upper end cap 4 and the lower end cap respectively.

[0034] Among them, in order to reduce the weight of the upper end cap 4, save raw materials, and reduce the manufacturing cost, one or more material-reducing holes 43 are also provided on the upper end cap 4.

[0035] The fixing holes 41 are arranged at intervals along the circumferential direction of the upper end cap 4, and the mounting holes are arranged at intervals along the circumferential direction of the lower end cap.

[0036] In an alternative embodiment, the lower end cap includes a first lower end cap part 6 and a second lower end cap part 7 that are detachably spliced together, and at least one locking assembly is connected to each of the first lower end cap part 6 and the second lower end cap part 7. By dividing the lower end cap into two detachable parts, it is convenient to disassemble the lower end cap and facilitate the installation of the universal ball 5 and the metal tube 9.

[0037] In an alternative embodiment, a step 10 is provided at each end of the first lower end cap part 6, and a step 10 is also provided at each end of the second lower end cap part 7. The steps 10 of the first lower end cap part 6 and the steps 10 of the second lower end cap part 7 cooperate with each other and are spliced together.

[0038] In an alternative embodiment, the locking assembly includes a locking member 1, a spring 2, and a pin 3. A groove is axially provided on the pin 3.

One end of the locking member 1 close to the upper end cap 4 extends into the groove of the pin 3 and is fixed to the other end of the pin 3. The other end of the locking member 1 is located outside the fixing hole. Both ends of the spring 2 respectively abut against the locking member 1 and the bottom wall of the fixing hole 41, thereby fixing the pin 3 on the upper end cap 4 and the lower end cap, and fixedly connecting the upper end cap 4 and the lower end cap at intervals in parallel.

[0039] Among them, by setting the spring 2, the locking degree of the shaft pin 3 can be well adjusted, so that the connection degree between the upper end cover 4 and the lower end cover can be adjusted, and the extrusion of the universal ball 5 by the upper end cover 4 and the lower end cover can be adjusted, so that the tightness of the rotation of the universal ball 5 can be adjusted, that is, the magnitude of the driving force for rotating the universal ball 5 can be adjusted. For example, when the locking degree of the shaft pin 3 is strengthened, a greater manual force is required to rotate the universal ball 5; conversely, when the locking degree of the shaft pin 3 is weakened, a smaller manual force can be used to rotate the universal ball 5.

[0040] The locking member 1 can be threadedly connected to the pin shaft or other connection methods. The locking member 1 is a bolt.

[0041] The utility model has a simple structure, firm connection, is not easy to wear, has a long service life, and by setting the universal ball 5, it is possible to rotate the metal pipe 9 connected to the universal ball 5 smoothly without applying film lubricating grease, avoiding food contamination, and by setting the spring 2, the touch of the driving force for rotating the universal ball 5 can be well adjusted, improving the user experience.
