Description

Technical Field

[0001] This utility model belongs to the field of temperature control technology, and more specifically, it relates to a hot and cold water mixing device. Background Technology

[0002] Winter heating is essential for ensuring residents' well-being. Precise control of the ratio of hot and cold water is necessary during heating. A hot and cold water mixing device is required to combine the cold and hot water and maintain the water temperature at the desired level, ensuring the convenience and stability of winter heating.

[0003] According to CN202422675912.0, this utility model relates to the field of hot and cold water equipment technology, and in particular to a hot and cold water system for pharmaceutical preparation. Technical problem: When using a hot and cold water system, the temperature difference between hot and cold water entering the mixing pipe can easily cause significant pressure inside the pipe. During prolonged operation, the conveying pipe is prone to damage, thus affecting normal preparation. Technical solution: A hot and cold water system for pharmaceutical preparation includes a preparation device body, a hot water component, a mixing component, a cold water component, a protection component, a drainage component, and a support component. Compared to traditional hot and cold water systems, where the temperature difference between hot and cold water entering the mixing pipe can easily cause significant pressure inside the pipe, and prolonged operation can easily damage the conveying pipe, thus affecting normal preparation, this hot and cold water system, by setting a mixing structure, can pre-treat the mixing of hot and cold water, effectively preventing the temperature difference from causing significant pressure inside the pipe.

[0004] Based on the above, existing hot and cold water mixing devices are generally sealed by a protective cover structure. When water is added into the device for mixing, the operator needs to open the cover first, then control the water pipe to flow out. After the water is added into the device and mixed, the cover needs to be closed manually, which makes the operation process cumbersome for the operator. Utility Model Content

When water is added into the device for mixing, the operator needs to open the cover first, then control the water pipe to flow out, and after the water is added into the device and mixed, the cover needs to be manually closed, which makes the operation process cumbersome for the operator.

[0006] The purpose and effect of this utility model's hot and cold water mixing device are achieved by the following specific technical means: A hot and cold water mixing device includes a mixing body, a mixing cover, a cold water pipe, a hot water pipe, a temperature display screen, a water outlet pipe, a sealing plate, a mixing sealing mechanism, and an opening mixing mechanism. The mixing cover is fixedly connected to the middle of the rear end face of the mixing body.

[0007] Furthermore, the mixing and sealing mechanism includes a sealing motor and a sealing shaft; the sealing motor is fixedly connected to the front side of the upper end face of the mixing body; the sealing shaft is coaxially fixedly connected to the shaft of the sealing motor, and the sealing shaft is rotatably connected to the inside of the upper end face of the mixing body.

[0008] Furthermore, the hybrid sealing mechanism also includes: a sealing pulley, a movable shaft, a movable pulley, and a movable transmission belt; the sealing pulley is coaxially and fixedly connected to the sealing shaft; the movable shaft is rotatably connected to the front side inside the upper end face of the hybrid body; the movable pulley is coaxially and fixedly connected to the movable shaft; the movable transmission belt is drivingly connected to the outer end faces of the sealing pulley and the movable pulley, and the sealing pulley, the movable pulley, and the movable transmission belt mesh together to form a synchronous belt drive mechanism.

[0009] Furthermore, the hybrid sealing mechanism also includes: a movable lead screw and a movable threaded hole; the movable lead screw is coaxially fixedly connected to the rear side of the movable rotating shaft, and the movable lead screw is rotatably connected to the rear side of the upper end face of the hybrid body; the movable threaded hole is opened in the middle position inside the sealing guard plate, and the movable lead screw and the movable threaded hole are threadedly connected.

[0010] Furthermore, the opening and mixing mechanism includes: a switch connecting block and a proximity switch; there are two sets of switch connecting blocks, which are fixedly connected to the left and right sides of the front end face of the sealing plate, and the two sets of switch connecting blocks slide on the left and right sides inside the upper end face of the mixing body; there are two sets of proximity switches, which are fixedly connected to the left and right sides inside the upper end face of the mixing body, and the two sets of switch connecting blocks slide on the rear side of the two sets of proximity switches.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention employs a hybrid sealing mechanism, in which a sealing motor drives a sealing plate to slide, and the sliding sealing plate seals the mixing body, thereby keeping the water inside the mixing body warm. This prevents the upper side of the mixing body from being exposed to the outside, which would cause the water inside the mixing body to cool down, thus ensuring the water temperature inside the mixing body.

[0013] This invention employs an opening mixing mechanism. When water is added to the mixing body from both cold and hot water pipes, the sealing motor drives the sealing plate to slide open. The opening of the sealing plate automatically controls the addition of water from both pipes. Once the water addition is complete, the sealing motor stops the water addition and then controls the sealing plate to slide close. This eliminates the need for manual operation of the sealing plate to open and close before adding water, saving operators time and making the mixing device more convenient for them.

[0025] The mixing sealing mechanism also includes a movable lead screw 11 and a movable threaded hole 1201.

[0026] The specific usage and function of this first embodiment are as follows: During use, the rotating shaft of the sealing motor 7 drives the sealing shaft 8 to rotate, which in turn drives the sealing pulley 801 to rotate.

The proximity switch 13 and the solenoid valve 14 are connected through an intermediate relay and a time relay. When the proximity switch 13 senses the switch connecting block 1202, the proximity switch 13 drives the time relay coil to be energized and starts timing. The intermediate relay self-locks and starts the solenoid valve 14. When the solenoid valve 14 is started, the water inside the cold water pipe 3 and the hot water pipe 4 is discharged into the mixing body 1 through the connecting pipe 15 for mixing. The time relay delays and disconnects the contact, the intermediate relay is de-energized, and the solenoid valve 14 stops, so that when the sealing plate 12 is opened, the cold water pipe 3 and the hot water pipe 4 drain water into the mixing body 1 according to the temperature.
