Description

Technical Field

[0001] The present application relates to the field of valve bodies, and in particular to a faucet. Background Art

[0002] A faucet is a device that precisely controls the flow of fluid to achieve accurate filling of canned containers. A faucet is usually composed of multiple components, including a valve core, a valve seat, a sealing ring, and a handle. The valve core is a key component for controlling the flow rate, and it can adjust the size of the opening by moving up and down or rotating. The valve seat and the valve core cooperate to form a sealing structure. The sealing ring is used to enhance the sealing and prevent material leakage. The handle is used to manually operate the faucet's switch.

[0003] When gas needs to be injected into the canned container, the faucet needs to be reinstalled at the gas outlet end of the gas storage barrel, which increases the steps of filling the canned container, prolongs the filling cycle of the canned container, and thus increases the filling cost of the canned container. Utility Model Content

[0004] In order to improve the problems in the steps of canning a canning container, the present application provides a faucet.

[0005] The present application provides a faucet, which adopts the following technical solution:

[0006] A faucet comprises a valve seat, a valve core, a valve stem and a plurality of starting components, wherein the valve seat has a rotating chamber for the valve stem to rotate, the valve core is connected to the end face of the valve stem, the valve core axis and the valve stem axis are parallel to each other, a plurality of feed holes are spaced apart on the outer peripheral surface of the valve seat, the starting components and the feed holes correspond one to one, a starting chamber for accommodating the starting components is formed on the inner wall of the feed hole, the starting chamber is connected to the rotating chamber, the starting component separates the starting chamber and the rotating chamber, and when the starting component abuts against the valve core, the starting chamber is connected to the rotating chamber.

[0007] By adopting the above technical solution, a plurality of feed holes are spacedly distributed on the outer peripheral surface of the valve seat. The beverage to be filled in barrels and the gas storage tank are respectively and correspondingly installed on the inner wall of the feed holes. The axis of the valve stem and the axis of the valve core are parallel to each other. By driving the valve stem to rotate, the valve core is driven to rotate towards the starting component communicated with the gas storage tank. The starting component abuts against the valve core, the starting cavity is communicated with the rotating cavity, the inner cavity of the gas storage tank, the liquid inlet hole, the starting cavity and the rotating cavity are communicated. The gas in the gas storage tank sequentially passes through the liquid inlet hole and the starting cavity and enters the rotating cavity, realizing the injection of the gas. When the gas injection is completed, the valve stem is driven to rotate, and the valve core is driven to rotate towards the starting rod communicated with the beverage in the barrel. The abutting effect of the valve core on the starting component communicated with the gas storage tank disappears. The starting component separates the rotating cavity and the starting cavity. At the same time, the valve core abuts against the starting component communicated with the beverage in the barrel. The inner cavity of the beverage in the barrel, the liquid inlet hole, the starting cavity and the rotating cavity are communicated. The beverage in the beverage barrel sequentially passes through the liquid inlet hole and the starting cavity and enters the rotating cavity, realizing the injection of the beverage. There is no need to disassemble the faucet from the beverage barrel and install it on the gas storage tank, reducing the steps of filling the canned container and shortening the filling cycle of the canned container, thereby reducing the filling cost of the canned container.

[0008] Optionally, the starting component includes a starting rod and an elastic member. One end of the elastic member in the direction of the elastic force is connected to the inner wall of the starting cavity, and the other end of the elastic member in the direction of the elastic force is connected to the rod surface of the starting rod. The elastic member has an elastic force to drive the starting rod to slide towards the direction close to the rotating cavity. The rod surface of the starting rod protrudes from the inner wall of the rotating cavity, and there is a tendency for the rod surface of the starting rod to abut against the inner wall of the starting cavity and separate the starting cavity and the rotating cavity. When the valve stem drives the valve core to rotate towards the direction close to one of the starting rods, the valve core abuts against the rod surface of the starting rod and drives the starting rod to slide towards the direction close to the starting cavity, and the abutting effect between the rod surface of the starting rod and the inner wall of the starting cavity disappears.

[0009] By adopting the above technical solution, the elastic member drives the starting rod to slide towards the direction close to the rotating cavity by elastic force. The rod surface of the starting rod abuts against the inner wall of the starting cavity and separates the starting cavity and the rotating cavity. When the valve stem rotates and drives the valve core to rotate towards the direction close to one of the starting rods, the valve core abuts against the rod surface of the starting rod and drives the starting rod to slide towards the direction close to the starting cavity. The abutting effect between the rod surface of the starting rod and the inner wall of the starting cavity disappears, and the starting cavity is communicated with the liquid inlet hole and the rotating cavity, realizing the directional opening and closing of the starting cavity and the rotating cavity, thereby improving the flexibility of using the faucet.

[0010] Optionally, a guiding surface is provided on the rod surface of the starting rod protruding from the rotating cavity. The guiding surface is in the shape of an arc protrusion, and the guiding surface can abut against the surface of the valve core and guide the starting rod to slide towards the direction close to the starting cavity.

[0011] By adopting the above technical solution, the guiding surface is in a convex arc shape. When the valve core rotates towards the starting rod, the guiding surface abuts against the surface of the valve core and guides the starting rod to slide towards the starting cavity. The starting cavity is communicated with the rotating cavity, realizing the directional start of the starting cavity and the rotating cavity, reducing the wear between the starting rod and the valve core, and thus prolonging the service life of the faucet.

[0012] Optionally, the starting assembly further includes a first sealing ring. The inner ring of the first sealing ring is sleeved on the outer peripheral surface of the starting rod, and the outer ring of the first sealing ring can tightly abut against the inner wall of the starting cavity to form a seal.

[0013] By adopting the above technical solution, when the elastic member elastically drives the starting rod to slide towards the rotating cavity, the guiding surface protrudes from the inner wall of the rotating cavity. The inner ring of the first sealing ring tightly abuts against the outer wall of the starting rod to form a seal, and the outer ring of the first sealing ring tightly abuts against the inner wall of the starting cavity to form a seal, further improving the abutting force between the rod surface of the starting rod and the inner wall of the starting cavity, and thus ensuring the stability of the separation between the rotating cavity and the starting cavity.

[0014] Optionally, the valve seat includes a control section, a gear, and an installation section. The rotating cavity is located on the control section. The gear is connected to the surface of the control section. One end of the installation section is provided with an internal tooth groove meshing with the gear. The other end of the installation section is provided with a limiting cavity for the bottle mouth to be inserted. The outer peripheral surface of the bottle mouth abuts against the inner wall of the limiting cavity to form a limit. The inner wall of the rotating cavity is provided with a discharge flow channel, and the discharge flow channel penetrates through the inner wall of the rotating cavity. The surface of the installation section facing the discharge flow channel is provided with a discharge flow channel, and the discharge flow channel communicates the limiting cavity and the discharge flow channel. The material in the rotating cavity can sequentially pass through the discharge flow channel, the discharge flow channel, and the limiting cavity and enter the inner cavity of the bottle.

[0015] By adopting the above technical solution, the gear is installed on the surface of the control section, and the inner tooth groove meshing with the gear is provided on the surface of the installation section. When the user needs to adjust the orientation of the faucet, the gear is driven to rotate on the inner wall of the inner tooth groove to realize the orientation adjustment of the control section on the installation section; at the same time, the bottle mouth to be filled is inserted into the limiting cavity, and the inner wall of the limiting cavity abuts against the outer peripheral surface of the bottle mouth to form a limit. The material in the rotating cavity sequentially passes through the discharge flow channel, the discharge flow channel, and the limiting cavity and enters the inner cavity of the bottle, realizing the stable supply of the material in the inner cavity of the bottle.

[0016] Optionally, the valve seat further includes a second sealing ring. The inner ring of the second sealing ring is coaxially sleeved on the gear rotating shaft, and the outer ring of the second sealing ring tightly abuts against the inner wall of the inner tooth groove to form a seal.

[0017] By adopting the above technical solution, the inner ring of the second sealing ring tightly abuts against the outer peripheral surface of the gear rotating shaft to form a seal, and the outer ring of the second sealing ring tightly abuts against the inner wall of the inner tooth groove to form a seal, making the material discharged from the liquid discharge flow channel not easily enter the inner tooth groove, ensuring the stable entry of the material in the liquid discharge flow channel into the discharge flow channel, and improving the sealing stability between the control section and the installation section.

[0018] Optionally, an arc-shaped clamping plate is connected to the inner wall of the limiting cavity, and the plate surface of the arc-shaped clamping plate facing the discharge channel can abut against the end surface of the bottle mouth and limit the bottle mouth in the limiting cavity.

[0019] By adopting the above technical solution, when the bottle mouth is embedded in the limiting cavity, the plate surface of the arc-shaped clamping plate facing the discharge channel abuts against the end surface of the bottle mouth and limits the bottle mouth in the limiting cavity, making it difficult for the bottle mouth to leave the limiting cavity, thereby improving the limiting stability of the bottle mouth in the limiting cavity.

[0020] Optionally, an exhaust channel 1 is opened on the bottom wall of the limiting cavity, and the exhaust channel 1 penetrates the outer wall of the installation section toward the control section. An exhaust channel 2 is opened on the outer wall of the control section. The exhaust channel 1 is connected to the exhaust channel 1, and an opening and closing rod is threadedly connected to the inner wall of the exhaust channel 2.

[0021] By adopting the above technical scheme, the opening and closing rod is threadedly screwed and fixed on the inner wall of the second exhaust flow channel to achieve the closure of the second exhaust flow channel. When the liquid in the rotating chamber is to be injected into the discharge flow channel, the discharge flow channel and the limiting cavity in sequence and enters the inner cavity of the bottle, the air pressure in the bottle is greater than the air pressure in the rotating chamber. The opening and closing rod is turned, and the closing effect of the opening and closing rod on the second exhaust flow channel disappears. The air in the bottle is discharged from the second exhaust flow channel through the exhaust flow channel, thereby achieving stable injection of the liquid in the bottle.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The arrangement of the valve seat, valve core, valve stem and starter assembly enables the injection of beverages without removing the faucet from the barreled beverage and installing it on the gas tank, thereby reducing the steps of filling the canned container and shortening the canning cycle of the canned container, thereby reducing the canning cost of the canned container;

[0024] 2. The setting of the starter rod and the elastic member eliminates the abutment effect between the starter rod surface and the inner wall of the starter cavity, and the starter cavity is connected to the liquid inlet hole and the rotating cavity, so as to realize the directional opening and closing of the starter cavity and the rotating cavity, thereby improving the flexibility of the faucet;

[0025] 3. The setting of the guide surface realizes the directional starting of the starting chamber and the rotating chamber, reduces the wear between the starting rod and the valve core, and thus extends the service life of the faucet. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following further Figures 1-3 describes the present application in detail.

[0031] An embodiment of the present application discloses a faucet. Referring to Figure 1 and Figure 2 , the faucet includes a valve seat 1, a valve core 2, a valve rod 3 and a plurality of starting components 4. A limiting cavity 17 for embedding the bottle mouth is opened at the bottom of the valve seat 1. The inner wall of the limiting cavity 17 abuts against the outer wall of the bottle mouth circumference to form a limit. A rotating cavity 18 for the valve rod 3 to rotate is opened on the top surface of the valve seat 1.

[0032] Referring to Figure 2 and Figure 3 , the end of the valve rod 3 protruding from the top surface of the valve seat 1 is fixed with a handle 5 by bolts. The valve core 2 includes a fixing part 21 and a connecting ring 22. A fixing groove 31 for embedding the end of the fixing part 21 is opened on the rod surface of the valve rod 3. The outer wall of the fixing part 21 abuts tightly against the inner wall of the fixing groove 31 to form a fixation. The axis of the fixing part 21 and the axis of the valve rod 3 are parallel to each other. An embedded groove 211 for embedding the connecting ring 22 is coaxially opened on the outer peripheral surface of the fixing part 21. The inner ring wall of the connecting ring 22 abuts tightly against the inner wall of the embedded groove 211 to form a fixation, and the outer peripheral surface of the connecting ring 22 is flush with the outer peripheral surface of the fixing part 21.

[0033] Referring to Figure 1 and Figure 2, a plurality of feed holes 11 are spaced apart on the outer wall of the valve seat 1. In the embodiment of the present application, the number of the feed holes 11 is three. One of the inner walls of the feed holes 11 is for installing the outlet end of the gas storage tank, and the other two feed holes 11 are for installing the liquid outlet ends of different barreled beverages. The starting components 4 correspond to the feed holes 11 one by one. A starting cavity 12 for accommodating the starting component 4 is formed on the inner wall of the feed hole 11. The starting cavity 12 communicates with the rotating cavity 18. The starting component 4 separates the starting cavity 12 and the rotating cavity 18. When the valve core 2 abuts against the starting component 4, the starting cavity 12 communicates with the rotating cavity 18, realizing the directional opening of a plurality of starting cavities 12 by the user, and realizing the directional injection of different materials into the inner cavity of the bottle. There is no need to disassemble the faucet from the barreled beverage and install it on the gas storage tank, reducing the steps of filling the canned container and shortening the filling cycle of the canned container, thereby reducing the filling cost of the canned container.

[0034] Referring to Figure 2 , the starting component 4 includes a starting rod 41, an elastic member 42 and a first sealing ring 43. The elastic member 42 can be a compression spring or a tension spring. In the embodiment of the present application, the elastic member 42 is a compression spring and has a certain deformation ability. The starting rod 41 is slidably connected to the inner wall of the starting cavity 12. The sliding direction of the starting rod 41 is perpendicular to the axis of the valve core 2. One end of the elastic member 42 in the direction of the elastic force is connected to the inner wall of the starting cavity 12, and the other end of the elastic member 42 in the direction of the elastic force is connected to the rod surface of the starting rod 41. The elastic member 42 has an elastic force to drive the starting rod 41 to slide in the direction close to the rotating cavity 18. The rod surface of the starting rod 41 protrudes from the inner wall of the rotating cavity 18, and there is a tendency for the rod surface of the starting rod 41 to abut against the inner wall of the starting cavity 12 and separate the starting cavity 12 and the rotating cavity 18.

[0035] Referring to Figure 2 , the material of the first sealing ring 43 can be a compression spring or a tension spring. In the embodiment of the present application, the material of the first sealing ring 43 is rubber and has a certain deformation ability. The inner ring of the first sealing ring 43 is coaxially sleeved on the end of the starting rod 41 close to the rotating cavity 18, and the outer wall of the first sealing ring 43 can abut against the inner wall of the starting cavity 12 to form a seal; a guiding surface 411 is provided at the end of the starting rod 41 protruding from the inner wall of the rotating cavity 18. The guiding surface 411 is in the shape of an arc protrusion. When the handle 5 is held and the valve core 2 is driven to rotate in the direction close to the guiding surface 411, the guiding surface 411 abuts against the outer wall of the connecting ring 22 and guides the starting rod 41 to slide in the direction close to the starting cavity 12. The abutting force between the rod surface of the starting rod 41 and the inner wall of the starting cavity 12 disappears, and the starting cavity 12 communicates with the rotating cavity 18 and the feed hole 11. The material sequentially passes through the feed hole 11 and the starting cavity 12 and enters the rotating cavity 18, realizing the stable injection of the material in the rotating cavity 18.

[0036] Referring to Figure 2, the valve seat 1 includes a control section 13, a gear 14, a mounting section 15, and a second sealing ring 16. The handle 5 is installed at one end of the control section 13, the gear 14 is fixed to the other end face of the control section 13, the limiting cavity 17 is located at one end of the mounting section 15, and an internal tooth groove 151 meshing with the gear 14 is provided at the other end of the mounting section 15. The material of the second sealing ring 16 can be rubber or silica gel. In the embodiment of the present application, the material of the second sealing ring 16 is rubber, which has a certain deformation ability. The inner ring of the second sealing ring 16 is coaxially sleeved on the outer peripheral surface of the rotating shaft of the gear 14, and the outer ring of the sealing ring abuts against the inner wall of the internal tooth groove 151 to form a seal; when it is necessary to adjust the orientation of the control section 13 on the mounting section 15, hold the outer wall of the control section 13 and drive the control section 13 to rotate, driving the gear 14 to rotate on the inner wall of the internal tooth groove 151, so as to realize the precise adjustment of the orientation of the control section 13 on the mounting section 15, and further improve the convenience of using the faucet.

[0037] Refer to Figure 2 , an arc-shaped clamping plate 6 is integrally formed and fixed on the inner wall of the limiting cavity 17. The plate surface of the arc-shaped clamping plate 6 facing the control section 13 can abut against the end face of the bottle mouth and limit the bottle mouth in the limiting cavity 17, so that the bottle mouth is not easily separated from the limiting cavity 17, thereby improving the stability of the bottle mouth limited in the limiting cavity 17.

[0038] Refer to Figure 2 , a discharge flow channel 131 is provided on the inner wall of the rotating cavity 18 close to the mounting section 15. The depth direction of the discharge flow channel 131 penetrates the outer wall of the control section 13 towards the direction close to the mounting section 15. An inlet liquid ring channel 153 is coaxially provided on the surface of the mounting section 15 facing the control section 13. The inlet liquid ring channel 153 surrounds the internal tooth groove 151, and the inlet liquid ring channel 153 communicates with the discharge flow channel 131. A discharge flow channel 152 is provided on the bottom wall of the inlet liquid ring channel 153. The depth direction of the discharge flow channel 152 penetrates the inner wall of the inlet liquid ring channel 153 towards the direction close to the limiting cavity 17 and communicates with the limiting cavity 17. The material in the rotating cavity 18 can sequentially pass through the discharge flow channel 131, the inlet liquid ring channel 153, the discharge flow channel 152, and the limiting cavity 17 and enter the inner cavity of the bottle, realizing the filling of the material in the inner cavity of the bottle.

[0039] Refer to Figure 2, an exhaust passage one 154 is provided on the bottom wall of the limiting cavity 17. The discharge passage 152 surrounds the exhaust passage one 154. The exhaust passage one 154 penetrates the outer wall of the installation section 15 in the depth direction towards the control section 13. An exhaust passage two 132 is provided on the outer wall of the control section 13. The exhaust passage two 132 penetrates the outer wall of the control section 13 and communicates with the exhaust passage one 154. A closing and opening rod 7 is threadedly connected to the inner wall of the exhaust passage two 132 away from the exhaust passage one 154. A handle 8 is fixed to the end of the closing and opening rod 7 protruding from the control section 13. When the air pressure in the inner cavity of the bottle is greater than the air pressure in the rotating cavity 18, hold the handle 8 and turn the handle 8 to drive the closing and opening rod 7 away from the exhaust passage two 132, realizing the opening of the exhaust passage two 132. The air in the bottle passes through the exhaust passage one 154 and is discharged from the exhaust passage two 132, realizing the pressure relief of the inner cavity of the bottle, so as to ensure the stable filling of the material in the inner cavity of the bottle.

[0040] The implementation principle of a faucet in an embodiment of the present application is as follows: The air outlet end of the gas storage tank is installed on the inner wall of one of the liquid inlet holes, and the discharging end of the barreled beverage is installed on the inner wall of the other feeding port. Hold the handle 5 and drive the valve rod 3 to rotate, driving the valve core 2 to rotate towards the starting cavity 12 communicating with the gas storage tank. The guiding surface 411 abuts against the surface of the valve core 2 and guides the starting rod 41 to slide towards the starting cavity 12. The abutting effect between the rod surface of the starting rod 41 and the inner wall of the starting cavity 12 disappears. The inner cavity of the gas storage tank, the liquid inlet hole, the starting cavity 12 and the rotating cavity 18 are communicated. The gas in the gas storage tank sequentially passes through the liquid inlet hole and the starting cavity 12 and enters the rotating cavity 18. The gas in the rotating cavity 18 sequentially passes through the discharging passage 131, the liquid inlet annular passage 153, the discharging passage 152 and the limiting cavity 17 and enters the inner cavity of the bottle, realizing the filling of the gas in the inner cavity of the bottle. When the gas filling in the bottle is completed, hold the handle 5 and drive the valve rod 3 to rotate, driving the valve core 2 to rotate towards the starting cavity 12 communicating with the barreled beverage. The guiding surface 411 abuts against the surface of the valve core 2 and guides the starting rod 41 to slide towards the starting cavity 12. The abutting effect between the rod surface of the starting rod 41 and the inner wall of the starting cavity 12 disappears. The barreled beverage, the liquid inlet hole, the starting cavity 12 and the rotating cavity 18 are communicated. The liquid in the barreled beverage sequentially passes through the liquid inlet hole and the starting cavity 12 and enters the rotating cavity 18. The liquid in the rotating cavity 18 sequentially passes through the discharging passage 131, the liquid inlet annular passage 153, the discharging passage 152 and the limiting cavity 17 and enters the inner cavity of the bottle, realizing the filling of the liquid in the inner cavity of the bottle.
