[0001] This utility model relates to foot bath tubs, specifically to a foot bath tub with an exothermic reaction tank. Background Technology
[0002] Chinese patent disclosure discloses a foot bath tub with application number CN202120713701.5. This foot bath tub, relating to the field of daily necessities, includes: a first heating zone, a cavity formed inside the bottom of the tub; a water inlet and a first vent hole on the tub wall; the water inlet communicating with the first heating zone via a water inlet pipe inside the tub wall; and the first vent hole communicating with the first heating zone via a vent pipe inside the tub wall; a first closable filling port on the bottom of the tub; and a second heating zone, a cavity formed inside the tub wall; a second closable filling port on the tub wall; a second filling cap movably disposed on the second filling port; and a second vent hole on the second filling cap; a self-heating pack can be placed into the first and second heating zones through the first and second filling ports; and heat is transferred to the water in the foot bath tub by adding the self-heating pack and water to the first and second heating zones.
[0003] Although the foot bath bucket described above can heat the water inside, it still has the following problem: because the first heating zone is opened on the wall of the foot bath bucket, and both the first heating zone and the second heating zone are isolated from the inner cavity of the foot bath bucket, the heating pack cannot come into contact with the water inside the foot bath bucket, making it difficult to heat the water inside the foot bath bucket. Utility Model Content
[0004] This utility model aims to provide a foot bath tub with an exothermic reaction tank, which solves the problem in the prior art that the water in the foot bath tub is difficult to heat because both the first heating zone and the second heating zone are isolated from the inner cavity of the foot bath tub.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] This utility model discloses a foot bath tub with an exothermic reaction tank, comprising: a tub body and a support plate; an exothermic reaction tank is formed on the bottom surface of the tub body, and an external heating pack is placed inside the exothermic reaction tank; a support plate is installed on the bottom surface of the tub body, the support plate is detachably connected to the tub body, and a water-permeable hole is provided on the support plate, which can connect the exothermic reaction tank to the inner hole of the tub body.
[0007] Preferably, the first end of the support plate is hinged to the barrel body, and the second end of the support plate is snapped to the barrel body.
[0008] Preferably, a rotating shaft protrudes from the first end of the support plate, and a rotating groove is formed by a recess in the bottom surface of the barrel. The rotating groove is located next to the exothermic reaction tank and is used to insert the rotating shaft, which can rotate within the rotating groove.
[0009] Preferably, the rotating groove includes an insertion groove and a rotating positioning groove. The insertion groove is located above the rotating positioning groove and is connected to the rotating positioning groove. The rotating positioning groove has a cylindrical structure and its diameter is greater than the width d of the insertion groove.
[0010] Preferably, the second end of the support plate extends to form a V-shaped buckle, and the bottom surface of the barrel is recessed to form a slot for inserting the V-shaped buckle. The inner wall of the slot engages with the V-shaped buckle.

[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] This application directly incorporates an exothermic reaction tank that communicates with the inner cavity of the tank. When there is water in the inner cavity of the tank and a heating pack is present in the exothermic reaction tank, the water releases heat upon contact with the heating pack, thereby heating the water. Simultaneously, a support plate covers the exothermic reaction tank, supporting the feet located above it and preventing the heating pack from directly contacting the feet. Compared with existing technologies, this provides better contact heating, a simpler overall tank structure, lower production costs, and enhanced market competitiveness.

[0022] To make the technical means, creative features, achieved objectives and functions of this utility model clearer and easier to understand, the utility model will be further described below with reference to the accompanying drawings and specific embodiments:
[0023] Example 1: As Figures 1 to 4 As shown, this utility model discloses a foot bath tub with an exothermic reaction tank 11, including: a tub body 1 and a support plate 2; an exothermic reaction tank 11 is formed on the inner bottom surface of the tub body 1, and an external heating pack is placed inside the exothermic reaction tank 11; a support plate 2 is installed on the inner bottom surface of the tub body 1, and the support plate 2 is detachably connected to the tub body 1. A water permeable hole 20 is provided on the support plate 2, and the water permeable hole 20 can connect the exothermic reaction tank 11 with the inner hole of the tub body 1.
[0024] The first end of the support plate 2 is hinged to the barrel 1, and the second end of the support plate 2 is snapped to the barrel 1. This allows the support plate 2 to be adjusted by rotation, so that the support plate 2 can open or close the heat release reaction tank 11. The water permeable hole 20 on the support plate 2 allows the heating pack to contact the water in the inner cavity of the barrel 1 to release heat after the support plate 2 is closed.
[0025] A rotating shaft 21 protrudes from the first end of the support plate 2. A rotating groove 12 is formed by a recess in the bottom surface of the barrel 1. The rotating groove 12 is located next to the exothermic reaction tank 11 and provides a place for the rotating shaft 21 to be inserted. The rotating shaft 21 can rotate within the rotating groove 12. The rotating groove 12 formed by the recess in the bottom surface of the barrel 1 allows the rotating shaft 21 on the support plate 2 to be pressed into the rotating groove 12 after the barrel 1 is inserted, thus guiding the rotation of the rotating groove 12 and facilitating the installation of the support plate 2.
[0026] The rotating groove 12 includes an insertion groove 121 and a rotating positioning groove 122. The insertion groove 121 is located above the rotating positioning groove 122 and is connected to the rotating positioning groove 122. The rotating positioning groove 122 has a cylindrical structure and the diameter of the rotating positioning groove 122 is greater than the width d of the insertion groove 121. Since the entire barrel 1 is made of plastic, it has a certain degree of flexibility. The diameter of the rotating positioning groove 122 matches the diameter of the rotating shaft 21. Although the width of the insertion groove 121 is smaller than the diameter of the rotating shaft 21, during the process of inserting the rotating shaft 21 into the rotating groove 122, the rotating shaft 21 is first pressed into the insertion groove 121. Utilizing the flexibility of the barrel 1 material, although the rotating shaft 21 is relatively larger than the insertion groove 121, the rotating shaft 21 can be slowly squeezed into the insertion groove 121 and finally squeezed into the rotating positioning groove 122. After the rotating shaft 21 is pressed into the rotating positioning groove 122, the connection between the insertion groove 121 and the rotating positioning groove 122 has a blocking effect, which restricts the rotating shaft 21 from detaching from the rotating positioning groove 122. The entire process of installing the support plate 2 only requires pressing the rotating shaft 21 into the insertion groove 121 and the rotating positioning groove 122, which is simple to operate.
[0027] The second end of the support plate 2 extends to form a V-shaped buckle 22, and the bottom surface of the barrel 1 is recessed to form a groove 13. The groove 13 is for the V-shaped buckle 22 to be inserted, and the inner wall of the groove 13 is engaged with the V-shaped buckle 22. This achieves a detachable connection between the second end of the support plate 2 and the barrel 1, so as to position the support plate 2 in the closed exothermic reaction tank 11 position.
[0028] Example 2: As Figure 5 As shown, a temperature sensor 3 is installed inside the tank 1. The temperature sensor 3 is used to detect the temperature inside the tank 1. This enables the detection of the water temperature inside the tank 1.
[0029] A pH sensor 4 is installed inside the tank 1. A temperature sensor 3 is connected to the first input terminal of a controller (not shown in the figure) through a first signal processing circuit. The pH sensor 4 is connected to the second input terminal of the controller through a second signal processing circuit. This enables the monitoring of the pH value of the water inside the tank 1.
[0030] A snap-on cover that allows only the legs to pass through can also be fastened on top of the bucket body 1. The snap-on cover is equipped with a display screen, which is connected to the controller, so that water data can be displayed when soaking feet.
[0031] A pressure sensor is also connected to the controller. The pressure sensor is installed at the bottom of the tank and monitors the water volume inside the tank.
[0032] The controller is also connected to a water browning level detection device. The heating pack is the color of traditional Chinese medicine, and the concentration of traditional Chinese medicine is determined by detecting the water browning level.
[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
