Description

Technical Field

[0001] This utility model relates to the field of valve faucet technology, specifically an antifreeze valve faucet. Background Technology

[0002] In some colder regions of northern China during winter, cold air can easily penetrate the valve faucet, causing ice to form inside. This ice can make the valve faucet difficult to open, or even damage it, affecting its lifespan and causing economic losses.

[0003] Publication number CN221665411U discloses an antifreeze valve faucet, including a valve faucet body, adjusting block, connecting rod, handle, water storage tank, sealing plate, heating wire, water inlet pipe, water inlet assembly, and insulation layer. By incorporating the heating wire, water storage tank, and water inlet assembly, the heating wire heats the water in the storage tank, raising the temperature of the valve faucet body and reducing the likelihood of ice formation inside. Furthermore, as water is continuously added to the storage tank, hot water enters the valve faucet body through the water inlet channel, facilitating direct contact between the hot water and the inner wall of the valve faucet body. This allows for faster thawing of the valve faucet body, reducing ice formation and making it easier to open. It also prevents damage caused by ice, extending the valve faucet's lifespan and reducing economic losses. However, this patent still has the following problems in practical use:

[0004] Most existing antifreeze faucets lack active defrosting functionality. Although the aforementioned devices can heat water for active cooling, the heating element distribution area is limited. When the faucet is clogged, hot water and the heating element are confined to the area near the heating element. For ice blocks in the faucet that are far from the heating element, the heat transfer efficiency is low. Furthermore, when the outside temperature is low and continues to affect the faucet, the defrosting efficiency will be further reduced.

[0005] An antifreeze valve tap is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide an antifreeze valve faucet to solve the problem that most existing antifreeze faucets lack active defrosting function. Although the aforementioned devices can heat water for active cooling, the distribution area of ​​the heating element is limited. When the faucet is blocked, hot water and the heating element are limited to the area near the heating element. For ice blocks in the faucet that are far from the heating element, the heat conduction efficiency is low. Furthermore, when the outside temperature is low and continues to affect the faucet, the defrosting efficiency will be further reduced.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an antifreeze valve faucet, comprising a faucet body, the faucet body including a valve, a water outlet pipe fixedly installed on one side of the valve, and a water inlet pipe fixedly installed on the other side of the valve;

[0008] An antifreeze assembly is provided on the outside of the valve. The antifreeze assembly includes a first protective cover and a second protective cover. The first protective cover has a first surrounding copper tube inside, and the second protective cover has a second surrounding tube inside. The first protective cover is fitted over the outside of the outlet pipe, and the second protective cover is fitted over the outside of the inlet pipe.

[0009] The bottom of the first protective cover is provided with a clearance groove, and the bottom surface of the clearance groove is provided with a sealing component.

[0010] The first circumferential copper tube has a connecting pipe fixedly connected to one end, the second circumferential tube has a connecting pipe fixedly connected to one end, and a retaining sleeve is installed at the bottom inner side of the second protective cover. The connecting pipe and the connecting pipe are connected by the retaining sleeve.

[0011] Preferably, the first surrounding copper tube is sleeved around the outside of the outlet pipe, and the other end of the first surrounding copper tube is fixedly connected to the inner wall of the first protective cover. The second surrounding tube is sleeved around the outside of the inlet pipe, and the other end of the second surrounding tube is fixedly connected to a terminal block.

[0012] Preferably, a stabilizing sleeve is fixedly connected to the top of one side of the second protective cover, and the wiring terminal is connected through to both the top of the second protective cover and the protective sleeve, and the protective sleeve is inserted into the sealing cover.

[0013] Preferably, the connecting pipe and the connecting tube are both located on one side of the valve, and the inner sides of the first protective cover and the second protective cover are both fixedly connected to the stabilizing sleeves, and the connecting pipe and the connecting tube are both connected through the stabilizing sleeves.

[0014] Preferably, the ferrule includes a connecting sleeve and a bolt, the bolt is threaded to one side of the connecting sleeve, the connecting sleeve is fixedly connected to the end of the connecting tube, the connecting tube is inserted into the connecting sleeve, and the bolt is through-connected to the outer side of the second protective cover.

[0015] Preferably, the sealing assembly includes a sealing plate covering the bottom of the clearance groove, and a docking plug is symmetrically and fixedly connected to the top surface of the sealing plate. The bottom of the first protective cover and the second protective cover are both provided with through holes, and the docking plug is inserted into the through holes with a small interference fit.

[0016] Preferably, both the first protective cover and the second protective cover are made of insulating, heat-insulating, and corrosion-resistant materials.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This antifreeze valve faucet, through a surround electric heating antifreeze mechanism, an insulating, heat-insulating, and corrosion-resistant protective cover, and a sealed and reinforced structure, achieves efficient active antifreeze, dustproof and leak-proof protection, and long-term stability, comprehensively ensuring the reliable operation of the valve faucet and pipeline safety in low-temperature environments. Its specific details are as follows:

[0018] 1. The first and second coiled copper pipes are respectively wrapped around the outside of the outlet and inlet pipes, forming a three-dimensional heating network to ensure uniform heating of all parts of the pipeline and effectively prevent the risk of local freezing. The protective cover is made of insulating, heat-insulating, and corrosion-resistant materials, which not only blocks heat loss to the external environment and improves insulation efficiency, but also avoids the risk of electric leakage and ensures safe use. The bolt locking design of the clamp sleeve enables quick disassembly and assembly of the pipeline connection, which is convenient for later maintenance. The through connection of the stabilizing sleeve enhances the structural stability of the copper pipe and the protective cover and prevents the connection from loosening due to vibration during operation. This component breaks through the limitations of traditional passive insulation through an electric heating active antifreeze mechanism, and is particularly suitable for the antifreeze needs of valves and faucets in low-temperature environments.

[0019] 2. Through the plug-in structure of the sealing plate and the docking plug, the overall structural stability of the antifreeze component is enhanced while achieving the sealing of the clearance groove. The sealing plate covers the bottom of the clearance groove, effectively preventing external cold air from seeping into the protective cover, reducing heat loss, and improving antifreeze efficiency. The small interference fit between the docking plug and the through hole ensures the reliability of the seal and allows for quick disassembly, facilitating the exposure of internal pipelines during maintenance. This component also enhances the docking strength between the first and second protective covers through physical connection, avoiding the risk of separation due to external impact or thermal expansion and contraction. In addition, the design of the sealing component also takes into account the dustproof function, preventing dust from entering the protective cover and adhering to the surface of the copper tube, affecting heating efficiency, and extending the service life of the equipment, reflecting the deep integration of structural design and functional requirements.

[0026] 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.

[0027] Please see Figures 1-5 The present invention provides a technical solution: an antifreeze valve faucet, including a faucet body 1, the faucet body 1 including a valve 101, a water outlet pipe 102 fixedly installed on one side of the valve 101, and a water inlet pipe 103 fixedly installed on the other side of the valve 101.

[0028] An antifreeze component 2 is provided on the outside of valve 101. The antifreeze component 2 includes a first protective cover 201 and a second protective cover 202. The first protective cover 201 has a first surrounding copper tube 2011 inside, and the second protective cover 202 has a second surrounding tube 2021 inside. The first protective cover 201 is fitted over the outside of the outlet pipe 102, and the second protective cover 202 is fitted over the outside of the inlet pipe 103. A clearance groove 2013 is provided at the bottom of the first protective cover 201, and a sealing component 3 is provided on the bottom surface of the clearance groove 2013. One end of the first surrounding copper tube 2011 is fixedly connected to a connecting pipe 2012, and one end of the second surrounding tube 2021 is fixedly connected to a connecting pipe 2022. A retaining sleeve 203 is installed at the inner bottom of the second protective cover 202. Connector 2022 and connector 2012 are connected by compression fitting 203. After connector 2012 and connector 2022 are joined by compression fitting 203, the second surrounding tube 2021, connector 2022, connector 2012 and first surrounding copper tube 2011 are electrically heated, which raises the internal cavity temperature of the first protective cover 201 and the second protective cover 202, preventing the temperature from dropping below zero and causing the liquid inside valve 101 to freeze. The first protective cover 201 and the second protective cover 202 can prevent the copper tube from accumulating dust or being damaged. During production and assembly, the water inlet pipe 103 is passed through the side wall of the second protective cover 202, and then the two are bonded together with glue. The joint of the first protective cover 201 and the second protective cover 202 can be bonded with glue, increasing the connection stability.

[0029] The first surrounding copper tube 2011 is sleeved around the outside of the water outlet pipe 102, and the other end of the first surrounding copper tube 2011 is fixedly connected to the inner wall of the first protective cover 201. The second surrounding tube 2021 is sleeved around the outside of the water inlet pipe 103, and the other end of the second surrounding tube 2021 is fixedly connected to a terminal block 2023. An external power supply is connected to the terminal block 2023 to power the second surrounding tube 2021.

[0030] A stabilizing sleeve 204 is fixedly connected to the top of one side of the second protective cover 202. The terminal block 2023 is connected through to the top of the second protective cover 202 and the protective sleeve 2024. The protective sleeve 2024 is inserted into the sealing cover 2025. The sealing cover 2025 and the protective sleeve 2024 are in a small interference fit. The protective sleeve 2024 and the sealing cover 2025 protect the terminal block 2023. At the same time, after the sealing cover 2025 is pulled out, the terminal block 2023 can be exposed to connect to an external power supply.

[0031] Both the connecting pipe 2012 and the connecting pipe 2022 are located on one side of the valve 101. The inner sides of the first protective cover 201 and the second protective cover 202 are fixedly connected with stabilizing sleeves 204. Both the connecting pipe 2012 and the connecting pipe 2022 are connected through the stabilizing sleeves 204. The stabilizing sleeves 204 can increase the stability of the second surrounding pipe 2021 and the connecting pipe 2022, and prevent them from shaking and affecting the docking.

[0032] The ferrule 203 includes a connecting sleeve and a bolt. The bolt is threaded to one side of the connecting sleeve, and the connecting sleeve is fixedly connected to the end of the connecting tube 2022. The connecting tube 2012 is inserted into the connecting sleeve, and the bolt is connected through to the outside of the second protective cover 202. During docking, the end of the connecting tube 2012 is inserted into the ferrule 203, and then the bolt is rotated to move it axially, thereby pressing the bolt against the connection end of the connecting tube 2022 and the connecting tube 2012 to achieve quick locking. The ferrule 203 is an existing docking tool.

[0033] The sealing assembly 3 includes a sealing plate 301 covering the bottom of the clearance groove 2013. A docking plug 302 is symmetrically and fixedly connected to the top surface of the sealing plate 301. The bottom of the first protective cover 201 and the second protective cover 202 are both provided with through holes 303. The docking plug 302 is inserted into the through hole 303 with a small interference fit. The clearance groove 2013 can avoid the water outlet pipe 102 during assembly. Then, the sealing plate 301 is connected to the through hole 303 by the docking plug 302, so that the sealing plate 301 not only seals the clearance groove 2013 to prevent air leakage, but also prevents the first protective cover 201 and the second protective cover 202 from separating. After the docking pipe 2012 is connected to the connecting pipe 2022, the connection stability of the first protective cover 201 and the second protective cover 202 is increased.

[0034] Both the first protective cover 201 and the second protective cover 202 are made of insulating, heat-insulating and corrosion-resistant materials; the insulating, heat-insulating and corrosion-resistant materials can be polyimide composite materials or carbon fiber materials.

[0035] Working principle: Before using this type of antifreeze valve faucet, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 5 As shown, the external power supply powers the second circumferential tube 2021 through the terminal 2023. The current is conducted to the first circumferential copper tube 2011 through the connecting tube 2022, the ferrule 203, and the connecting tube 2012, forming a closed heating circuit.

[0036] When the copper tubes inside the two protective covers are energized, they generate heat, which raises the temperature of the internal cavities of the first protective cover 201 and the second protective cover 202, preventing the liquid in the valve 101 from freezing due to low temperature.

[0037] During assembly, the inlet pipe 103 passes through the side wall of the second protective cover 202 and is fixed with glue. The outlet pipe 102 is inserted into the first protective cover 201. The connecting pipe 2012 and the connecting pipe 2022 are mechanically sealed through the clamp 203. After the bolts are tightened, the ends of the two pipes are pressed to achieve quick locking.

[0038] The sealing plate 301 of the sealing component 3 is fitted with the through hole 303 by the small interference fit of the mating plug 302. This not only seals the clearance groove 2013 to prevent air leakage, but also enhances the docking stability of the first protective cover 201 and the second protective cover 202 through physical connection, while preventing the copper pipe from being covered by dust or external mechanical damage.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
