[0001] The utility model relates to the field of water buckets, in particular to a water bucket capable of keeping water at a constant temperature. Background Art

[0002] After searching, Chinese patent document CN205825399U discloses an electric constant temperature fully automatic bathtub, including a bathtub body, which is provided with an automatic water inlet and water outlet system, which includes a water inlet pipe and a water outlet pipe respectively connected to the bathtub cavity, a solenoid valve I is provided on the water inlet pipe, and a solenoid valve II is provided on the water outlet pipe, and the solenoid valve I and the solenoid valve II are respectively connected to the water inlet and water outlet control circuit; the bathtub body is also provided with a temperature control system, which includes a temperature sensor provided on the surface of the bathtub cavity, a heat preservation layer provided on the inner layer of the bathtub cavity, and a heating layer located between the heat preservation layer and the bathtub cavity, and the temperature control system also includes a temperature control circuit, which is electrically connected to the temperature sensor and the heating layer respectively. The electric constant temperature fully automatic bathtub can realize timed water inlet and water outlet, timed heating, and control the water inlet volume and heating temperature, thereby realizing constant temperature control of water in the bathtub cavity.

[0003] Chinese patent document CN203447211U discloses an automatic health-preserving constant temperature foot soaking bucket, including a base, a barrel body is provided on the base, the barrel body is made of wood material, and the bottom of the barrel body is provided with a water suction hole and a water spray hole, and at the same time, a water pump and a heating device are provided in the base, the water pump has a water inlet end and a water outlet end, the heating device has a water inlet and a water outlet, and the water suction hole is connected to the water inlet end, the water outlet end is connected to the water inlet, and the water outlet is connected to the water spray hole, and a temperature sensor is provided between the water suction hole and the water inlet end, or between the water outlet end and the water inlet, or between the water outlet and the water spray hole, the temperature sensor is connected to a temperature controller, and the temperature controller is connected to the heating device. The automatic health-preserving constant temperature foot soaking bucket can have a good ability to keep the water temperature constant and is convenient for having a health-preserving function.

[0004] Chinese patent document CN201749384U discloses a smart foot bath constant temperature control device, including a barrel, a temperature sensor, an AC power supply, a heating device and an intelligent control circuit; the temperature sensor, AC power supply, heating device and intelligent control circuit are all installed in the barrel; the output of the temperature sensor is connected to the intelligent control circuit; the output of the AC power supply is connected to the intelligent control circuit; the output of the intelligent control circuit is connected to the heating device; it also includes a flow sensor for sensing whether there is water in the barrel; the flow sensor is installed above the bottom of the barrel, and the output of the flow sensor is connected to the intelligent control circuit. When there is water in the barrel, it can intelligently start the constant temperature control device and intelligently control the temperature within a constant and appropriate range without artificial or mechanical control of the water temperature.

[0005] It can be seen that in terms of controlling constant temperature, the prior art including CN205825399U, CN203447211 U and CN201749384U all disclose the use of temperature sensors to detect temperature, send the detected signal to the controller or control circuit for control, and execute whether to heat up the temperature through the heating layer or heating device. For example, CN205825399U discloses that the temperature control system also includes a temperature control circuit, which is electrically connected to the temperature sensor and the heating layer respectively. The temperature control circuit receives the temperature data of the temperature sensor and compares it with the preset temperature threshold. When the temperature is higher than the temperature threshold, it does not act, and when the temperature value is lower than the temperature threshold, it controls the heating layer to heat.

[0006] However, the heating wire in the spacer between the insulation layer and the bathtub cavity in CN205825399U heats the bathtub body and the insulation layer, and then the bathtub body conducts and heats the water, rather than directly heating the water, resulting in a higher temperature of the bathtub body. CN203447211 U and CN201749384U disclose foot bath tubs or foot bath tubs, so the heating device is located at the bottom in the structural design, making the bottom temperature higher, and there is no need to set a thermal insulation layer.

[0007] At present, the bucket that can keep water at a constant temperature is used as a bathing bucket. There is no such product on the market, and there is no prior art disclosed after searching, so the utility model is produced. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only preferred embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1-Figure 3 As shown, a water bucket capable of maintaining a constant temperature of water comprises an inner barrel body 11, an outer barrel body 12, an annular heating belt 2, a temperature sensor 3 and a control circuit board 4.

[0033] There is a cavity 13 between the inner barrel body 11 and the outer barrel body 12 , and an annular recessed area 14 is provided at the middle end of the outer barrel body 12 ; through holes 15 communicating with the cavity 13 are provided at the upper and lower ends of the side wall of the inner barrel body 11 .

[0034] The annular heating belt 2 is fixed in the annular recessed area 14. As a specific embodiment, a protective net 16 is provided at the end of the annular recessed area 14 to prevent the annular heating belt from falling. As a specific embodiment, a waterproof heat-insulating coating is coated in the annular recessed area. Currently, there are waterproof heat-insulating coating agents available on the market and in the prior art that can be applied and used. The function of the waterproof heat-insulating coating is to further reduce heat loss.

[0035] The temperature sensor 3 is fixed on the outer barrel 12 and extends into the cavity 13. Specifically, the temperature sensor 3 can be located above the annular heating belt 2. As a specific implementation, the temperature sensor can be selected as a thermocouple. Thermocouples have the advantages of simple structure and high precision. In addition, thermocouples are passive sensors and do not require external power supply during measurement.

[0036] A control circuit board 4 is fixed in the outer barrel body 12; the temperature sensor 3 and the annular heating belt 2 are electrically connected to the control circuit board 4. As a specific embodiment, the control circuit board 4 is provided with a switch 41, which is arranged on the side wall of the outer barrel body 12. The switch can be a key switch. In this way, when the water temperature is kept within the threshold range and used for half an hour, the switch can be directly pressed to turn it off. As a further specific embodiment, a display screen 42 is provided on the side wall of the outer barrel body 12, and the display screen 42 is electrically connected to the control circuit board 4. The display screen 42 is used to display information including temperature information, for example, also including time information. In this way, it is convenient for users to use, and they can directly observe whether the current temperature value is uniform, as well as the soaking time. Of course, the control circuit board can work by powering the battery.

[0037] As a specific implementation, the outer barrel body 12 may be provided with a wire groove (not shown), and the wires of the temperature sensor 4 and the annular heating belt 2 may be arranged along the wire groove.

[0038] As a specific embodiment, the inner barrel body 11 and the outer barrel body 12 are connected to a drain pipe 17, and the drain pipe 17 leading to the drain port of the inner barrel body is provided with a detachable cover 18. In this way, it is convenient to drain water after use.

[0039] As a specific implementation, the inner barrel body 11 can be inserted into the outer barrel body 12, and can also be taken out from the outer barrel body 12. This is convenient for installation and maintenance.

[0040] When working, first add warm water to the inner barrel body 11, and the inner barrel body 11 and the outer barrel body 12 form a communicating vessel. After adding to the required liquid level 19, an annular heating belt 2 is set in the outer barrel body 12, and the temperature is measured by the temperature sensor 3, so that the temperature of the water in the outer barrel body can be monitored in real time. When the temperature of the water drops beyond the set threshold range (for example, the set temperature threshold range is 43-45°C), the annular heating belt 2 is used to heat and supplement the heat to raise the temperature to the set threshold, so that the water can be kept at a constant temperature. This water bucket has the effect of real-time temperature regulation, so that the temperature is kept at a constant temperature level within the threshold range.

[0041] To make the water bucket safer, the temperature threshold range can be set to a maximum value through the control circuit board, for example, the maximum value is 45°C. When the temperature sensor detects 45°C, the heating of the annular heating belt will be automatically stopped, and 45°C is also the highest temperature that the annular heating belt can heat to.

[0042] On the one hand, the annular heating belt 2 is fixed in the annular recessed area 14 of the outer barrel body 12, and the temperature sensor 3 is fixed on the outer barrel body 12 and extends into the cavity 13, so that the temperature can be measured by the temperature sensor 3, and the water temperature in the bucket can be monitored in real time. When the temperature of the water drops beyond the set threshold range, the annular heating belt is used to heat and supplement the heat to raise the temperature to the set threshold, so that the temperature of the water can be controlled within a constant and appropriate range. When a person is in the bucket, the fluidity of the water will increase.

[0043] On the other hand, the annular heating belt 2 is fixed in the annular recessed area 14 of the outer barrel body 12, and the upper and lower ends of the side walls of the inner barrel body 11 are provided with through holes 15 communicating with the cavity 13. In this way, the water temperature in the outer barrel body 12 is generally slightly higher than the water temperature in the inner barrel body 11. Therefore, the water in the outer barrel body 12 not only heats the water in the inner barrel body 11 when flowing, but also serves as an insulation layer surrounding the outside of the inner barrel body 11.

[0044] The series of detailed descriptions listed above are only specific descriptions of feasible embodiments of the present invention. They are not intended to limit the protection scope of the present invention. All equivalent embodiments or changes that do not deviate from the technical spirit of the present invention should be included in the protection scope of the present invention.
