Description

Technical Field

[0001] The utility model relates to the technical field of water-heating electric blankets, in particular to a water shortage alarm and power-off device for water-heating electric blankets. Background Art

[0002] Water-heated electric blankets have replaced traditional electric blankets in the market. Using water as a heating medium, they generate no electromagnetic radiation and are non-drying, thus eliminating harmful electromagnetic radiation and safety risks. Compared to traditional electric blankets, water-heated electric blankets have become a popular choice for many households. Currently, water-heated electric blankets are equipped with a water pump. As long as the water pump is functioning properly, it heats the water and then pumps it into the blanket to dissipate heat, thereby achieving the desired heating effect. Because the water in the water tank of a water-heated electric blanket is constantly circulating and heating, moisture is lost. If the water tank is insufficient, not only will the heating effect be reduced, but it can also cause the blanket to dry out, damaging the main unit. Therefore, existing water-heated electric blankets are equipped with a water shortage alarm and power-off device to improve safety.

[0003] For example, the prior art publication number CN210570937U is a water shortage alarm and power-off device for a water-heating electric blanket. This utility model uses a float, a micro switch lever and an operating button, and uses a buzzer to sound an alarm, which can remind people to add water in time, avoid dry burning, and increase the service life of the water-heating electric blanket.

[0004] However, the above-mentioned existing technology still has the following problems when in use: a float switch is used to judge the water shortage state in the water tank of the water-heating electric blanket, and the contacts are easily touched by mistake, causing a false alarm, which in turn affects the normal use of the water-heating electric blanket. Based on this, the utility model provides a water shortage alarm power-off device for the water-heating electric blanket. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Refer to the instruction manual Figure 1-Figure 5 The utility model provides a water shortage alarm power-off device for a water-heating electric blanket, which is used to monitor the water tank 11 of the water-heating electric blanket host 10, including a water shortage monitoring component 1 and a fixing component 2. The water shortage monitoring component 1 includes an ultrasonic liquid level meter 101 and an alarm 102, and the fixing component 2 is used to install the ultrasonic liquid level meter 101.

[0026] During use, the ultrasonic level meter 101 is installed in the water inlet of the water tank 11 through the fixing component 2, and the ultrasonic level meter 101 is used to send ultrasonic waves generated in the water tank 11, and then receive the ultrasonic waves. By measuring the time it takes for the ultrasonic waves to travel back and forth, the height of the water level inside the water tank 11 is calculated, with high monitoring accuracy, and the monitoring data is sent to the water heating electric blanket host. Once the water level is lower than the safe range, it indicates a lack of water, and the water heating electric blanket host automatically cuts off the power. At the same time, the alarm immediately sounds an alarm to notify the user to replenish water in time to avoid affecting the normal use of the water heating electric blanket. The ultrasonic level meter 101 is used to monitor the water level in the water tank 11 in real time, with high measurement accuracy. It can monitor both the lack of water in the water tank 11 and the water level in the water tank 11, so it is convenient for users to control the amount of water.

[0027] Refer to the instruction manual Figure 1-Figure 5 The fixing assembly 2 includes a sleeve 201, which is sleeved on the outside of the ultrasonic level meter 101. A plurality of bolts 9 are passed through the outer wall of the sleeve 201. The plurality of bolts 9 are threadedly connected to the sleeve 201. One end of the plurality of bolts 9 is in contact with the outer wall of the ultrasonic level meter 101, which facilitates the installation and removal of the ultrasonic level meter 101. A detachable threaded cover 202 is fixed on the top of the sleeve 201. The threaded cover 202 is inserted into the water inlet of the water tank 11 and is threadedly connected to the water inlet of the water tank 11.

[0028] The alarm 102 is fixedly embedded in the top of the threaded cover 202, and a slot 3 is provided at the bottom of the threaded cover 202. The sleeve 201 is inserted into the slot 3, which facilitates the quick insertion of the sleeve 201 into the slot 3. A socket 4 is fixedly embedded at the bottom of the slot 3. A plug 5 connected to the terminal of the ultrasonic level meter 101 is fixedly embedded on one side of the top of the sleeve 201, and the plug 5 is plugged into the socket 4.

[0029] In addition, two protrusions 6 are fixedly provided on the outer wall of the sleeve 201, and two grooves 7 are provided on the inner wall of the slot 3 to match the protrusions 6. The two protrusions 6 are respectively arranged in the two grooves 7. The protrusions 6 cooperate with the grooves 7 to facilitate the quick installation of the sleeve 201. The bottom of the threaded cover 202 contacts the top of the water-heating electric blanket host 10, which is used to improve the firmness between the threaded cover 202 and the water inlet of the water tank 11.

[0030] Moreover, a rubber sealing ring 8 for improving sealing is provided between the outer wall of the threaded cover 202 and the inner wall of the water inlet of the water tank 11, so that the rubber sealing ring 8 can improve the sealing between the threaded cover 202 and the water inlet of the water tank 11.

[0031] In actual use, the sleeve 201 and the threaded cover 202 can be fixed together with the bolts 9. When not in use, the bolts 9 can be loosened to separate the sleeve 201 from the threaded cover 202, and then the multiple bolts 9 fixing the ultrasonic liquid level meter 101 on the sleeve 201 can be loosened to remove the ultrasonic liquid level meter 101 from the sleeve 201 for inspection. When reinstalling, just align the two protrusions 6 with the two grooves 7 respectively and insert them. The plug 5 on the sleeve 201 will automatically be inserted into the socket 4. Use an electric wire to connect the socket 4 to the water-heating electric blanket host 10, so that the water-heating electric blanket host 10 can also receive the monitored water level data.
