Description

Technical Field

[0001] The utility model relates to the technical field of bathroom faucets, in particular to a bathroom faucet with an antifreeze function. Background Art

[0002] In real life, bathroom faucets are easily frozen and unusable when used in winter when the temperature is very low. Therefore, many kinds of faucets with anti-freeze function have appeared on the market.

[0003] After searching, it was found that in the prior art, such as the Chinese patent (authorization number: CN217301865U), there is a faucet with an anti-freeze structure for bathroom use. The device can be suitable for faucet pipes of different lengths. The spacing between the three positioning rings can be adjusted according to the needs of the user. The water pipe can be heated and heated by the heating ring to avoid freezing inside the faucet. In addition, an insulating layer is used inside the heating device to maintain the unidirectional heat transfer during the heating process, thereby indirectly improving the heating efficiency of the water pipe.

[0004] Although the spacing between the three positioning rings in the above patent can be adjusted to improve the heating efficiency of the water pipe, there is still a spacing between each positioning ring, so that only the water in the water pipe at the position of the positioning ring can be locally heated, and the efficiency is still not high. Therefore, improvement is needed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a bathroom faucet with an antifreeze function, which solves the problems mentioned in the background technology.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] A bathroom faucet with an antifreeze function comprises a control valve, one side of the control valve is fixedly connected to a water outlet elbow, the other side of the control valve is fixedly connected to a water pipe, and one end of the water pipe away from the control valve is fixedly connected to a threaded pipe.

[0008] Compared with the prior art, the most important difference of the present invention is that the water pipe is externally connected with an electric heating device which can be adjusted to any length thereon, and the electric heating device includes a telescopic heating structure which is sleeved on the outside of the water pipe, and both ends of the telescopic heating structure are provided with a locking structure to lock it on the water pipe.

[0009] Specifically in the utility model, the telescopic heating structure includes a flexible insulation sleeve, an elastic heating element is arranged inside the insulation sleeve, and the elastic heating element is a spring electric heating coil. Both ends of the insulation sleeve and the elastic heating element are fixed between two locking structures.

[0010] After the telescopic heating structure is telescoped on the water pipe, in order to lock it, the locking structure includes a slip ring sleeved on the water pipe, and a locking piece is vertically installed on the slip ring to lock it on the water pipe. The locking piece is a bolt threadedly installed on the slip ring, and the bolt head is pressed against the surface of the water pipe.

[0011] Compared with the prior art, the utility model has the following beneficial effects: by unscrewing the bolts on the two slip rings, the insulation sleeve and the spring electric heating ring can be extended and retracted on the water pipe to change the heating range, and can cover the entire water pipe as much as possible to cope with water pipes of different lengths, thereby improving the heating efficiency.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0018] like Figure 1 As shown, the utility model provides a bathroom faucet with an antifreeze function, including a control valve 1, one side of the control valve 1 is fixedly connected to a water outlet elbow 2, the other side is fixedly connected to a water pipe 3, and a threaded pipe 4 is fixedly connected to the end of the water pipe 3 away from the control valve 1. The above structures are all prior arts.

[0019] like Figure 2-4 As shown, the main difference between the present invention and the prior art is that an electric heating device capable of adjusting any length is connected to the outer surface of the water pipe 3, and the electric heating device includes a telescopic heating structure connected to the outside of the water pipe 3, and a locking structure is provided at both ends of the telescopic heating structure to lock it to the water pipe 3.

[0020] like Figure 2As shown, in the utility model, the telescopic heating structure includes a flexible insulation sleeve 5, the material of the insulation sleeve 5 can be rock wool, aluminum foil, etc., an elastic heating element is arranged in the insulation sleeve 5, and the elastic heating element is a spring electric heating coil 6. The spring electric heating coil 6 is a prior art, and its principle is not repeated here. The spring electric heating coil 6 is connected to an external power supply to heat the water pipe 3 to prevent the water in the water pipe 3 from freezing, thereby ensuring the normal use of the entire faucet, and the spring electric heating coil 6 is spiral, which increases the contact area with the water pipe, and further improves the heating rate of the water in the water pipe 3. The insulation sleeve 5 prevents heat from being lost too quickly, and both ends of the insulation sleeve 5 and the elastic heating element are fixed between two locking structures.

[0021] like Figure 1 As shown, after the telescopic heating structure is telescoped on the water pipe 3, in order to lock it, the locking structure includes a slip ring 7 sleeved on the water pipe 3, and a locking member for locking it on the water pipe 3 is vertically installed on the slip ring 7, and the locking member is a bolt 8 threadedly installed on the slip ring 7, and the bolt head of the bolt 8 is pressed against the surface of the water pipe 3.

[0022] When the length of the electric heating device needs to be adjusted, the bolt 8 is screwed upward until the bolt 8 is removed from the slip ring 7, so that the slip ring 7 can slide along the water pipe 3, thereby driving the insulation sleeve 5 and the spring electric heating ring 6 to extend or retract until the entire water pipe 3 is covered as much as possible, and then the bolt 8 is screwed downward until the bolt head of the bolt 8 is pressed against the surface of the water pipe 3, thereby locking the slip ring 7 and then locking the entire electric heating device.

[0023] Finally, the most important contribution of the utility model compared with the prior art is that by unscrewing the bolts 8 on the two slip rings 7, the insulation sleeve 5 and the spring electric heating ring 6 can be extended and retracted on the water pipe 3 to change the heating range. In response to water pipes 3 of different lengths, the entire water pipe 3 can be covered as much as possible to improve the heating efficiency.

[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
