Haircutting can be a family activity, with family members and friends helping each other. A barbershop is equipped with hair washing equipment, which usually boils water in a water heater and then uses a shower to spray water to wash the customer's hair. A large amount of water is used in this process, and this water is usually discharged directly into the sewage pipe, which causes the heat to be unable to be reused and wastes a lot of energy.

[0003] In order to solve the above problems, a Chinese patent with announcement number CN202915771U discloses a heat recovery device, which is provided with a water tank body for storing waste water with residual heat, and passes clean water through a corrugated hose in the water tank body to recover the heat of the waste water. However, the device has certain defects in actual use. For example, although the device can store waste in the water tank body, it cannot monitor the temperature of the water in the water tank body. If the water temperature in the water tank body is low, the waste water with residual heat is discharged into the water tank body, resulting in a decrease in the temperature of the overall waste water. In addition, when the device is used in a shampooing tank, the hair inside is not filtered, which may easily cause the water outlet to be blocked by hair and difficult to clear.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments.

[0023] Example 1

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, a heat recovery device includes: a recovery box 1, a circular ring-shaped shampooing frame 101 arranged on one side of the top of the recovery box 1, a conical guide frame 102 connected to the bottom of the shampooing frame 101, a filtering component arranged in the guide frame 102, used for filtering the hair in the guide frame 102, and a monitoring component arranged inside the recovery box 1, used for monitoring the water temperature in the recovery box 1.

[0025] Among them, the filter component includes: a filter frame 2 arranged inside the guide frame 102, a filter net 201 embedded in the bottom of the filter frame 2, and a fitting block 202 connected to the top of the filter frame 2. When the device is used, the hair entering the guide frame 102 is filtered and intercepted by the filter component to prevent the hair from clogging the sewage pipe 703 and the drain pipe 7 and becoming difficult to clean. The filter component is easy to disassemble, making it easy to clean the hair in the filter frame 2, thereby ensuring the normal use of the filter component.

[0026] Among them, both sides of the outer end of the filter frame 2 are connected with sliders 3, both sides of the inner wall of the guide frame 102 are provided with slide grooves 301 slidably connected with the sliders 3, and a round rod 302 is installed inside the filter frame 2. When the shampoo frame 101 is used to wash the customer's hair, the fallen hair passes through the shampoo frame 101 and falls into the filter frame 2 in the guide frame 102, and then the hair is filtered and intercepted by the filter net 201, while the sewage passes through the filter net 201. When the hair in the filter frame 2 needs to be cleaned, the filter is filtered through the round rod 302. The frame 2 is lifted up until the slider 3 slides out of the slide groove 301, and then the filter frame 2 is removed from the guide frame 102, so that the hair in the filter frame 2 can be cleaned easily. After the filter frame 2 is cleaned, the filter frame 2 is moved into the guide frame 102, and the slider 3 is slid into the slide groove 301, so that the filter frame 2 is installed and limited in the guide frame 102, and the outer side of the fitting block 202 fits with the inner wall of the guide frame 102 to prevent the hair from entering the slide groove 301 and being discharged from the sewage pipe 703.

[0027] Example 2

[0028] Based on Example 1, Figure 1 and Figure 2 The monitoring component includes: a temperature sensor 4 installed on one side of the inner wall of the recycling box 1, a display screen 401 installed on one side of the outer end of the recycling box 1, and a buzzer 402 arranged on one side of the display screen 401. When the device is used, the temperature of the water in the recycling box 1 can be monitored by the monitoring component for viewing, so that the user can choose whether to drain the sewage in the recycling box 1, and when the temperature is low, an alarm can be sounded to prompt the user to drain the water in the recycling box 1, so as to avoid the water with lowered temperature in the recycling box 1 mixing with the subsequent water with residual temperature, resulting in a low overall sewage temperature, thereby affecting the heat recovery of the sewage.

[0029] Among them, a control panel 5 is installed on one side of the outer end of the recycling box 1, and the temperature sensor 4 is electrically connected to the display screen 401 and the control panel 5 respectively, and the control panel 5 is electrically connected to the buzzer 402. When the monitoring component is used, the temperature of the water in the recycling box 1 is monitored by the temperature sensor 4, and the temperature sensor 4 transmits the detected temperature value to the display screen 401 to facilitate the user to check the water temperature in real time. When the water temperature in the recycling box 1 is too low, the temperature sensor 4 activates the buzzer 402 through the control panel 5 to issue a prompt sound to allow the user to drain the water in the recycling box 1 in time.

[0030] Among them, the model of the temperature sensor 4 can be WZP-291, and its working principle is: the temperature sensor 4 is generally composed of three parts: a temperature sensitive element, a conversion element and a temperature conversion circuit. The function of the temperature sensitive element is to convert the sensed temperature signal into an easily measurable quantity that has a certain relationship with the temperature; the function of the conversion element is to convert the physical quantity output by the temperature sensitive element into an electrical quantity output; the function of the conversion circuit is to convert the electrical quantity output by the conversion element into an easily measurable electrical quantity, such as voltage, current, frequency, etc. The circuit and signal connection method between the temperature sensor 4 and the control panel 5 also belongs to the public conventional technology, so the circuit and signal connection relationship will not be repeated.

[0031] Example 3

[0032] Based on Example 1, Figure 1 and Figure 2 , one end of the heat recovery pipe 6 is connected to a water inlet pipe 601, and the other end of the heat recovery pipe 6 is connected to a water delivery pipe 602. A plurality of support blocks 603 are installed on one side of the inner wall of the recovery box 1, and the top of the support block 603 is connected to the heat recovery pipe 6. When the device is used, the water inlet pipe 601 is connected to an external water pipe, and the water delivery pipe 602 is connected to an external water heater, so that when the water heater is used, water enters the heat recovery pipe 6 from the water inlet pipe 601 and is transported to the water delivery pipe 602, and finally enters the water heater to heat the water and then discharge the water to wash the customer's hair. When the water passes through the heat recovery pipe 6, the water in the heat recovery pipe 6 can be heat exchanged with the sewage in the recovery box 1, so that the water in the heat recovery pipe 6 is preliminarily heated, so that the heat of the sewage can be recovered. The material of the heat recovery pipe 6 can be made of aluminum alloy material. The heat recovery pipe 6 made of aluminum alloy material has good temperature conductivity, so that the clean water in the heat recovery pipe 6 can have good heat exchange with the sewage in the recovery box 1, thereby enhancing the heat recovery of the sewage.

[0033] Among them, a drainage pipe 7 is connected to one side of the recycling box 1, and a control valve 701 is arranged on the outside of the drainage pipe 7. A circular fitting frame 702 is connected to the top of the hair washing frame 101. A sewage pipe 703 is connected between the recycling box 1 and the guide frame 102. A liquid level window 704 is inlaid on one side of the outer end of the recycling box 1. When the hair washing frame 101 is used to wash the customer's hair, the fitting frame 702 fits with the customer's neck. The fitting frame 702 can be made of sponge material to ensure the customer's comfort and wash the hair. The sewage after the head passes through the filter 201 and enters the recovery box 1 from the drain pipe 703 for heat recovery. When the water in the recovery box 1 needs to be discharged, the drain pipe 7 is connected to the external drain pipe, and the control valve 701 is opened to allow the water in the recovery box 1 to be discharged from the drain pipe 7. The liquid level window 704 is used to check the liquid level in the recovery box 1, so that it can be discovered in time that there is a lot of sewage in the recovery box 1 and it can be discharged through the drain pipe 7, thereby avoiding the sewage in the recovery box 1 from overflowing from the drain pipe 703.

[0034] The device is provided with a filter component to filter the hair in the guide frame to prevent the hair from flowing into the recycling box. The specific method is: when using the shampoo frame 101 to wash your hair, the fallen hair passes through the shampoo frame 101 and falls into the filter frame 2 in the guide frame 102, and then the hair is filtered and intercepted by the filter net 201, and the sewage will pass through the filter net 201 and enter the recycling box 1 from the sewage pipe 703 for heat recovery.
