Description

Technical Field

[0001] This utility model relates to the technical field of water supply auxiliary equipment, specifically to an induction-type water outlet antifreeze and heat preservation device. Background Technology

[0002] Induction-operated faucets are widely used in modern public facilities and homes due to their water-saving, hygienic, and intelligent features. However, in winter or cold environments, the water inside is prone to freezing, causing pipes or valves to crack, resulting in leaks or even permanent equipment damage. Existing antifreeze measures have the following shortcomings: First, the use of electric heating tape is inconvenient to install, results in a messy appearance, has low heat utilization, and may lead to localized overheating or antifreeze failure due to uneven winding; Second, some solutions attempt to integrate heating elements inside the faucet, but this requires significant modifications to the existing faucet structure, is costly, and is not suitable for existing equipment, resulting in poor versatility. Therefore, there is an urgent need for a dedicated antifreeze and insulation device that can be easily installed as a standalone accessory, effectively and actively heats the faucet while providing intelligent insulation, without altering the original faucet structure.

[0014] 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.

[0015] Please see Figure 1 and Figure 2 The first sleeve 1 has mounting blocks 2 on both sides of the top, mounting holes 201 in the middle of the mounting blocks 2, an infrared sensing device 3 and a temperature sensor 4 on one side wall of the first sleeve 1, and a spiral electric heating wire 6 on the inner wall of the first sleeve 1. The first sleeve 1 is provided with an installation groove 101. The bottom of the first sleeve 1 is sleeved with the second sleeve 7 through the installation groove 101. The installation groove 101 is provided with a partition 8. The top of the partition 8 is provided with a spare battery 9. The bottom of the partition 8 is fixedly connected to the top of a plurality of electric push rods 10. The bottom output end of the electric push rod 10 is fixedly connected to the top of the second sleeve 7. A power interface 5 is also provided on the upper end of the side wall of the first sleeve 1; A control unit 14 is also provided on the inner wall of the mounting groove 101. The control unit 14 is electrically connected to the infrared sensing device 3, the temperature sensor 4 and the electric heating wire 6.

[0016] Through the above technical solution, the mounting block 2 and the mounting hole 201 work together to provide a stable mounting foundation for the entire device; the infrared sensor 3 is responsible for detecting whether the user is approaching, while the temperature sensor 4 monitors the ambient temperature in real time and transmits the signal to the core control unit 14; the control unit 14 intelligently controls the start and stop of the spiral electric heating wire 6 to provide a heat source based on the received signal, and directs the extension and retraction of the electric push rod 10; the electric push rod 10, as an actuator, drives the second sleeve 7 to rise and fall relative to the first sleeve 1, thereby realizing the opening and closing of the protective chamber; the power interface 5 is used to connect to the external main power supply, while the backup battery 9 ensures the continuous operation of key functions when the external power is cut off, thus jointly realizing a fully automatic anti-freeze and heat preservation function that integrates intelligent sensing, active heating and mechanical protection.

[0017] Preferably, the inner wall of the mounting groove 101 near the electric heating wire 6 and the inner wall of the second sleeve 7 are both provided with a heat insulation layer 11; the heat insulation layer 11 is made of rubber insulation cotton.

[0018] Through the above technical solution, the heat insulation layer 11 set on the inner wall of the mounting groove 101 and the inner wall of the second sleeve 7 works in conjunction with the spiral electric heating wire 6 to effectively block the loss of internal heat to the external environment and greatly improve the efficiency of heat energy utilization. Among them, rubber insulation cotton is selected as the material of the heat insulation layer 11, which makes full use of its excellent heat resistance, low thermal conductivity and flexible sealing characteristics, so that the anti-freeze insulation device can achieve continuous and efficient heat preservation while achieving the beneficial effects of energy saving, consumption reduction and safety and reliability.

[0019] Preferably, a baffle 12 is provided at the bottom of the inner wall of the second sleeve 7, a plurality of drainage holes 1201 are provided on the baffle 12, a through hole 1202 is provided in the middle of the baffle 12, and a plurality of silicone sealing gaskets 13 are provided in the circumferential direction of the through hole 1202.

[0020] Through the above technical solution, the baffle 12 and the through hole 1202 set at the bottom of the second sleeve 7 together constitute the receiving and passing structure of the water outlet; the multiple silicone sealing gaskets 13 arranged in the circumferential direction can tightly fit the outer circumference of water outlets of different specifications, effectively sealing the bottom of the second sleeve 7, and together with the second sleeve 7 in the lifting process, forming a sealed and heat-insulating space that isolates external cold air; while the multiple drain holes 1201 set on the baffle 12 can promptly drain a small amount of condensate or accidental water ingress into the sealing gasket 13, avoiding internal water accumulation and freezing that could cause the mechanism to jam, thereby significantly improving the sealing reliability, environmental adaptability and antifreeze stability of the device.

[0021] The working principle of this utility model is as follows: In low-temperature environments, the control unit 14 continuously monitors the signals from the temperature sensor 4 and the infrared sensor 3. The device is powered by an external main power supply via the power interface 5 and charges the backup battery 9. When the temperature is below the set threshold and there is no need for use, the control unit 14 activates the electric push rod 10 to push the second sleeve 7 down, completely accommodating the water outlet in the sealed space formed by the first sleeve 1 and the second sleeve 7. At this time, the silicone sealing gasket 13 at the bottom of the second sleeve 7 and the baffle 12 together form a sealing barrier. Simultaneously, the control unit 14 activates the spiral electric heating wire 6 to heat and keep the sealed space warm. When the external power supply is unexpectedly interrupted, the control unit 14 automatically switches to the backup battery 9 to continue maintaining the normal operation of the device. When the infrared sensor 3 detects someone approaching, the control unit 14 immediately stops the electric heating wire 6 and controls the electric push rod 10 to pull the second sleeve 7 up to fully expose the water outlet. After use, the device automatically returns to the anti-freeze and heat preservation state.
