Technical Field

[0001] The present application relates to the technical field of faucets, and specifically relates to an anti-freezing faucet. Background Art

[0002] A faucet is a common name for a water valve used to control the size of the water flow switch, with the effect of saving water. The replacement speed of faucets is very fast. It has developed from the old cast iron process to the electroplated rotary type, and then to the stainless steel single-temperature single-control faucet, stainless steel double-temperature double-control faucet, and semi-automatic kitchen faucet. Now, more and more consumers will comprehensively consider various aspects such as material, function, and shape when purchasing a faucet.

[0003] A prior patent (publication number: CN219933395U) discloses an anti-freezing faucet, including a water outlet pipe. An outlet assembly is provided above the water outlet pipe, and a heat preservation assembly is provided on the outer surface of the outlet assembly. The heat preservation assembly includes a protective sleeve. One side of the protective sleeve is provided with a bag mouth, and a binding band is wound inside the bag mouth. It relates to the technical field of faucets. Among them, a heat preservation assembly is sleeved outside the outlet assembly, which includes a protective sleeve and a bag mouth. The bag mouth is sleeved outside the outlet assembly, then the bag mouth extends to one side of the support rod, and then the bag mouth and the support rod are tied tightly. Under the action of the protective sleeve, the outlet assembly is heat-preserved, avoiding the problem of freezing of the outlet assembly due to the low temperature outside.

[0004] In the process of using the above document, the components are heat-preserved through the protective sleeve, but the heat preservation effect of the protective sleeve is limited. When the temperature is relatively low, the low temperature outside will still freeze the water in the pipeline, and its practicability needs to be improved. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the present application provides an anti-freezing faucet, which has the advantages of improving the anti-freezing ability, etc., and solves the problems raised in the background art.

[0006] To achieve the above object, the present application provides the following technical solution: an anti-freezing faucet, including a connecting piece, a cavity is provided inside the connecting piece, a plurality of sealing pieces are slidably connected inside the cavity, one end of each of the plurality of sealing pieces away from each other is fixedly connected to a sliding rod, each of the plurality of sliding rods is slidably inserted into the connecting piece, one end of each of the plurality of sliding rods away from each other is fixedly connected to a spring, the other end of each of the plurality of springs is fixedly connected to the inner wall of the cavity, a water supply pipe is fixedly communicated with the upper surface of the connecting piece, a water pumping cylinder is installed on the outer surface of the water supply pipe, the upper end of the water pumping cylinder is fixedly communicated with a water suction pipe, the water suction pipe is located at the bottom end of the water supply pipe, a sliding member is slidably connected inside the water pumping cylinder, a one-way valve is installed on the upper surface of the sliding member, a drain pipe is fixedly communicated with the outer surface of the water pumping cylinder, and a valve is installed at the upper end of the water supply pipe.

[0007] Through the above solution, the cooperation of the valve and multiple seals can seal the bottom and top of the pipeline, and the excess water source in the water supply pipe is pumped out through the cooperation of the sliding member and the one-way valve, so that the inside of the water supply pipe is in a cavity state.

[0008] Furthermore, a toothed ring is rotatably connected to the inner wall of the connecting member, and a plurality of arc-shaped top blocks distributed in a circular pattern are fixedly connected to the inner wall of the toothed ring, and each of the plurality of sliding rods contacts the arc-shaped top block adjacent to it.

[0010] Furthermore, one end of each of the plurality of sliding rods away from each other is provided in a circular convex shape.

[0011] Through the above solution, one end of the sliding rod being provided in a circular convex shape can facilitate the contact between the arc-shaped top block and the sliding rod, thereby facilitating the arc-shaped top block to push the sliding rod to slide, so that a plurality of seals can seal the connecting member.

[0012] Furthermore, a rotating rod is rotatably connected to the inner wall of the connecting member, a gear is fixedly connected to the bottom end of the rotating rod, and the gear is meshed with the toothed ring.

[0013] Through the above solution, installing the rotating rod can facilitate the user to drive the gear to rotate, and its meshing with the toothed ring can drive the toothed ring to rotate.

[0016] Furthermore, each of the plurality of springs is in a compressed state.

[0017] Through the above solution, installing the springs can, through the deformation force of the springs, make a plurality of seals move away from each other during the reverse rotation of the rotating rod, so that the water flow can circulate again.

[0018] Furthermore, one ends of the plurality of seals close to each other are all in contact.

[0030] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0031] Please refer to Figure 1 , Figure 2 andFigure 3 In this embodiment, an anti-freezing faucet includes a connecting member 1. A cavity 2 is formed inside the connecting member 1. A plurality of seals 3 are slidably connected inside the cavity 2. One end of each of the plurality of seals 3 facing away from each other is fixedly connected to a slide bar 4. The plurality of slide bars 4 are all slidably inserted into the connecting member 1. One end of each of the plurality of slide bars 4 facing away from each other is fixedly connected to a spring 5. The other ends of the plurality of springs 5 are all fixedly connected to the inner wall of the cavity 2. A water supply pipe 6 is fixedly connected to the upper surface of the connecting member 1. A water pumping cylinder 7 is installed on the outer surface of the water supply pipe 6. The upper end of the water pumping cylinder 7 is fixedly connected to a water suction pipe 20. The water suction pipe 20 is located at the bottom end of the water supply pipe 6. A sliding member 8 is slidably connected inside the water pumping cylinder 7. A one-way valve 9 is installed on the upper surface of the sliding member 8. A drain pipe 10 is fixedly connected to the outer surface of the water pumping cylinder 7. A valve 11 is installed at the upper end of the water supply pipe 6. Through the cooperation of the valve 11 and the plurality of seals 3, the bottom end and the upper end of the pipeline can be closed, and through the cooperation of the sliding member 8 and the one-way valve 9, the excess water source in the water supply pipe 6 can be pumped out. When the water source in the water supply pipe 6 is pumped out, since there is no water source in the water supply pipe 6, the water source can be prevented from freezing in the water supply pipe 6. Since the lower water supply pipe 6 is located in the soil, the water source inside it can be prevented from freezing, thereby improving the anti-freezing effect.

[0032] Please refer to Figure 1 、 Figure 2 and Figure 3 , a toothed ring 12 is rotatably connected to the inner wall of the connecting member 1. A plurality of arc-shaped top blocks 13 distributed in a circular pattern are fixedly connected to the inner wall of the toothed ring 12. The plurality of slide bars 4 are all in contact with the arc-shaped top blocks 13 close to them. By installing the toothed ring 12, during the rotation of the toothed ring 12, the cooperation between the arc-shaped top blocks 13 and the slide bars 4 can push the plurality of seals 3 to close the connecting member 1 and block the flow of water. One end of each of the plurality of slide bars 4 facing away from each other is provided in a circular convex shape. The one end of the slide bar 4 being provided in a circular convex shape can facilitate the contact between the arc-shaped top block 13 and the slide bar 4, thereby facilitating the arc-shaped top block 13 to push the slide bar 4 to slide, enabling the plurality of seals 3 to close the connecting member 1. A rotating rod 14 is rotatably connected to the inner wall of the connecting member 1. A gear 15 is fixedly connected to the bottom end of the rotating rod 14. The gear 15 is meshed with the toothed ring 12. Installing the rotating rod 14 can facilitate the user to drive the gear 15 to rotate. When it meshes with the toothed ring 12, it can drive the toothed ring 12 to rotate. A fixing member 16 is installed at the upper end of the water supply pipe 6. The rotating rod 14 is rotatably connected to the fixing member 16. A limiting ring 17 is fixedly connected to the outer surface of the rotating rod 14. A plurality of limiting holes 18 distributed in a circular pattern are formed between the limiting ring 17 and the fixing member 16. A plug rod 19 is inserted into the limiting hole 18 on the left side. The cooperation of installing the limiting ring 17 and the plug rod 19 can limit the rotating rod 14 and prevent the rotating rod 14 from rotating in the reverse direction.

[0033] Please refer to Figure 1 、Figure 2 and Figure 4 At this time, multiple springs 5 are all in a compressed state. Installing the springs 5 can, through the deformation force of the springs 5, make multiple seals 3 move away from each other during the reverse rotation of the rotating rod 14, enabling water flow to resume. One end of each of the multiple seals 3 that are close to each other is in a contact state. When the multiple closures approach each other, they can seal the connecting member 1 and, under the push of the sliding rod 4 and the arc-shaped top block 13, can be in close contact, thereby being able to seal the connecting member 1. The outer surface of the sliding member 8 is made of rubber and is in close contact with the inner wall of the water pumping cylinder 7. The edge of the sliding member 8 being made of rubber can be closely connected to the water pumping cylinder 7, which can prevent pressure imbalance inside the water pumping cylinder 7 during the water pumping process.

[0034] An anti-freezing faucet in this embodiment can, through the cooperation of the valve 11 and multiple seals 3, seal the bottom and top ends of the pipeline, and through the cooperation of the sliding member 8 and the check valve 9, pump out the excess water source in the water supply pipe 6. When the water source in the water supply pipe 6 is pumped out, since there is no water source in the water supply pipe 6, the water source can be prevented from freezing in the water supply pipe 6. Since the lower water supply pipe 6 is located in the soil, the water source inside it can be prevented from freezing, thereby improving the anti-freezing effect.

[0035] The working principle of the above embodiment is as follows: When taking anti-freezing measures for the water supply pipe 6, first rotate the rotating rod 14 to make the rotating rod 14 drive the gear 15 to engage with the toothed ring 12. Driven by the gear 15, the toothed ring 12 can rotate within the connecting member 1. During the rotation of the toothed ring 12, it can drive multiple arc-shaped top blocks 13 to contact multiple sliding rods 4, enabling the multiple sliding rods 4 to push multiple seals 3 to approach and contact each other to seal the connecting member 1. When the connecting member 1 is sealed, the water flow can be cut off. At this time, use the cooperation of the insertion rod 19 and the limit ring 17 to limit the rotating rod 14 to prevent the rotating rod 14 from rotating in reverse. After the water flow is cut off, pull the sliding member 8 to make the sliding member 8 slide within the water pumping cylinder 7. Through the cooperation of the check valve 9 and the water extraction pipe, the water source in the water supply pipe 6 can be pumped out and discharged through the drain pipe 10. Since there is no water source in the water supply pipe 6, the water source can be prevented from freezing in the water supply pipe 6. Since the lower water supply pipe 6 is located in the soil, the water source inside it can be prevented from freezing, thereby improving the anti-freezing effect.
