Description

Technical Field

[0001] The utility model relates to the field of faucets, in particular to a cast bathroom faucet. Background Art

[0002] A bathroom faucet is a device that provides cold and hot water in a bathroom or toilet. Users can control the water flow rate and water temperature through a handle, which is convenient and fast to use.

[0003] The left and right sides of the bathroom faucet are usually connected to the pipes supplying cold and hot water. Since the faucet uses a metal shell, it is easily heated by hot water and has a relatively high temperature. If a user accidentally touches the side where the faucet is connected to the hot water pipe, it is easy to cause the user to be scalded (a faucet for preventing scalding disclosed in the patent publication No. CN212564526U also mentions this technical problem in the background art). The purpose of the present utility model is to propose a new faucet structure to solve the above technical problem. Summary of the Utility Model

[0004] The purpose of the present utility model is to provide a cast bathroom faucet to solve the problems mentioned in the background art.

[0005] To achieve the above purpose, the present utility model provides the following technical solutions: It includes a faucet body, a cold water pipe, a hot water pipe, and a heat insulation cavity. A handle for controlling the water output of the faucet body is provided on the faucet body. The cold water pipe is communicated with the faucet body, and a cold water installation pipe communicated with the cold water pipe is provided on the cold water pipe. The hot water pipe is communicated with the faucet body, and a hot water installation pipe communicated with the hot water pipe is provided on the hot water pipe. The heat insulation cavity surrounds the front, top, and bottom of the hot water pipe, and the heat insulation cavity is communicated with the cold water pipe through a communication pipe.

[0006] As a further improvement to the above technical solution: The length of the heat insulation cavity is greater than the length of the hot water pipe. The purpose of such a design is to prevent the user from touching the end of the hot water pipe and being scalded. The length of the heat insulation cavity exceeding that of the hot water pipe can play a blocking effect.

[0007] As a further improvement to the technical solution: There is a gap between the heat insulation cavity and the hot water pipe without direct contact. Its setting purpose is for insulation, to prevent the heat energy utilization efficiency of the hot water in the hot water pipe from decreasing due to direct contact heat conduction, and at the same time, the gap can play a heat insulation role to prevent the heat insulation cavity from being quickly heated by the hot water pipe.

[0008] As an improvement to the foregoing technical solution: The number of communication pipes is 2 and the communication pipes are located behind the faucet body. Locating the communication pipes behind the faucet body can reduce the probability of the communication pipes being touched and avoid damage to the communication pipes.

[0009] To optimize the above technical solution, the further measures taken are as follows: The hot water installation pipe is located behind the hot water pipe, and the length direction of the hot water installation pipe is perpendicular to the length direction of the hot water pipe. Such a structural arrangement can streamline the structure of the faucet, enabling the heat insulation cavity to block the hot water pipe and the hot water installation pipe, and reducing the probability of users accidentally touching the hot water installation pipe.

[0010] As can be seen from the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages:

[0011] A cast bathroom faucet provided by the present invention covers the hot water pipe by setting a heat insulation cavity to prevent users from directly contacting the hot water pipe and being scalded. At the same time, the connecting pipe is connected to the cold water pipe to take away the heat of the heat insulation cavity, and the heat insulation cavity can be prevented from being heated and raised in temperature by the hot water pipe.

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0017] Embodiment

[0018] Please refer to Figure 1-2, the present utility model provides a cast bathroom faucet, including a faucet body 1, a cold water pipe 2, a hot water pipe 3 and a heat insulation cavity 4. A handle 101 for controlling the water output of the faucet body 1 is provided on the faucet body 1. The faucet body 1 refers to the main body structure of the prior art faucet, which belongs to the prior art, so no further explanation of its specific structure and working principle will be given. The faucet body 1 can be a knob type, a single handle type, a double handle type or an electric control type, etc. Technicians can select according to actual needs during implementation, which will not have a substantial impact on the technical effect.

[0019] The cold water pipe 2 is connected to the faucet body 1, and a cold water installation pipe 201 connected to the cold water pipe 2 is provided on the cold water pipe 2.

[0020] The hot water pipe 3 is connected to the faucet body 1, and a hot water installation pipe 301 connected to the hot water pipe 3 is provided on the hot water pipe 3. The hot water installation pipe 301 is located behind the hot water pipe 3, and the length direction of the hot water installation pipe 301 is perpendicular to the length direction of the hot water pipe 3.

[0021] The heat insulation cavity 4 surrounds the front, top and bottom of the hot water pipe 3. The longitudinal section of the heat insulation cavity 4 is in a C shape. The length of the heat insulation cavity 4 is greater than the length of the hot water pipe 3. There is a gap between the heat insulation cavity 4 and the hot water pipe 3 without direct contact. The heat insulation cavity 4 is connected to the cold water pipe 2 through a connecting pipe 401. The number of the connecting pipes 401 is 2 and the connecting pipes 401 are located behind the faucet body 1.

[0022] Working principle: The cold water installation pipe 201 and the hot water installation pipe 301 are respectively used to connect with the pipes providing cold water and hot water. Hot water enters the hot water pipe 3 from the hot water installation pipe 301 to provide hot water for the faucet body 1. Cold water enters the cold water pipe 2 from the cold water installation pipe 201 to supply water to the faucet body 1. The user can control the handle 101 to change the water output flow rate and water output temperature of the faucet body 1.

[0023] The heat insulation cavity 4 covering the hot water pipe 3 can play a blocking role to prevent the user from being scalded by direct contact with the hot water pipe 3. At the same time, the heat insulation cavity 4 is connected to the cold water pipe 2 through the connecting pipe 401. When the heat insulation cavity 4 is heated by the hot water pipe 3, the cold water in the connecting pipe 401 and the cold water pipe 2 takes away the heat of the heat insulation cavity 4, which can prevent the heat insulation cavity 4 from being heated by the hot water in the hot water pipe 3 and causing the user to be scalded by accidentally touching the heat insulation cavity 4.

[0024] The length of the hot water pipe 3 is less than the length of the heat insulation cavity 4. The part of the heat insulation cavity 4 exceeding the hot water pipe 3 can play a blocking role to prevent the user from being scalded by contacting the end of the hot water pipe 3.

[0025] Although the present utility model 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
