Referring to fig. 1 to 5, an embodiment of the present utility model provides an evaporation pan including an evaporation pan body 1 and a capacitance detection mechanism 2. The capacitance detection mechanism 2 is arranged on the evaporation tray body 1 and is used for detecting capacitance values corresponding to liquid in the evaporation tray body 1 at different liquid level heights in real time.

The evaporation tray body 1 is used for containing liquid, and when the evaporation tray body 1 is placed on a horizontal plane and the liquid level of the liquid in the tray is in a static state, the free liquid level of the liquid is higher than the height of the lowest point in the tray of the evaporation tray body 1 to be the liquid level. The capacitance detection mechanism 2 is arranged on the evaporation tray body 1, when the evaporation tray works, liquid in the evaporation tray evaporates due to heating, the liquid in the evaporation tray body 1 also gradually decreases, the liquid level continuously decreases, at this time, the capacitance detection mechanism 2 detects capacitance values corresponding to the liquid in the evaporation tray body 1 at different liquid level heights in real time, and the approximate height of the current liquid level can be judged through the capacitance values.

Through setting up electric capacity detection mechanism 2 in evaporating dish body 1, this mechanism utilizes the difference of the electric capacity parameter of air medium and liquid medium, carry out the feedback of the electric capacity value of different liquid levels, electric capacity detection mechanism 2 can directly feed back the how much of liquid in the dish like this, can avoid indirectly detecting (through temperature sensor indirect detection) because the influence of factors such as evaporating dish material, coating film technology, use incrustation scale and mounted position, reduce the deviation that the measurement produced, avoid evaporating dish temperature to judge unusual leading to producing dry combustion method misjudgement, and then cause the condition emergence of disk body dry combustion method fracture.

As shown in fig. 1 to 5, the upper surface of the evaporation tray body 1 is recessed inward to form a cavity 11, and the lower surface of the evaporation tray body 1 is protruded outward through the cavity 11 to form a boss 12, wherein the cavity 11 is used for containing liquid. The capacitance detecting mechanism 2 includes a capacitance sensor 21 and a conductive member 22, the capacitance sensor 21 is electrically connected to the conductive member 22, and the conductive member 22 is disposed in the cavity 11.

The capacitance sensor 21 may be mounted on the evaporation pan body 1 by screws. The capacitive sensor 21 can be installed on the boss 12 or in the cavity 11, and if the capacitive sensor 21 is arranged in the cavity 11, the capacitive sensor 21 is connected with the conducting piece 22; if the capacitance sensor 21 is provided on the boss 12, the conductive member 22 passes through the evaporation pan body 1 to be connected with the capacitance sensor 21.

As shown in fig. 5, the conductive member 22 in the present embodiment is a spring structure, and in some embodiments, the conductive member 22 may be a probe or other metal tool. The conductive element 22 is placed in the cavity 11 containing the liquid, the conductive element 22 acts as one pole of the capacitor, the cavity wall acts as the other pole of the capacitor, and the medium between the two poles is the liquid and the gas above the liquid. Because the relative dielectric constant of the liquid is different from that of the air on the liquid level, and the relative dielectric constant of the liquid is larger than that of the air, when the liquid level rises, the total dielectric constant value between the two poles is increased, and the capacitance is also increased, otherwise, when the liquid level height is reduced, the total dielectric constant value between the two poles is reduced, and the capacitance is also reduced. Thus, the current liquid level height can be determined by the magnitude of the measured capacitance value.

As shown in fig. 3, the evaporation pan further includes a protective cover 3, the protective cover 3 is disposed in the cavity 11, and the conductive member 22 is disposed in the protective cover 3, and the protective cover 3 can be used to prevent the conductive member 22 from contacting with the liquid in the cavity 11 for a long time to prevent the conductive member 22 from being corroded or rusted.

In the embodiment of the application, the material of the protective cover 3 is a metal material, and the lower end part of the protective cover 3 is welded with the concave cavity 11 or connected through the sealing ring, so that the liquid in the concave cavity 11 cannot enter the protective cover 3. The shield 3 is designed with an open upper end, and the upper end of the shield 3 needs to be exposed to the liquid surface to prevent liquid from entering the shield 3 to contact the conductive member 22.

By adding the design of the protective cover 3, the conducting piece 22 can be protected in the protective cover 3, and the direct contact between the conducting piece 22 and the liquid in the concave cavity 11 of the evaporating pan body is avoided, because the conducting piece 22 possibly rusts in the process of being in direct contact with the liquid in the concave cavity 11 for a long time, and further, the deviation is generated in the process of detecting the capacitance sensor 21 in real time.

As shown in fig. 4, the evaporation pan further includes a heat generating structure 4, and the heat generating structure 4 is disposed on the boss 12 for heating the evaporation pan body 1.

Alternatively, the heat generating structure 4 may be a heat generating tube, and may be other devices for generating heat. In this embodiment, the heating structure 4 is a heating tube, and the heating tube is fixed on the boss 12. The heat generating tube is fixed to the boss 12.

On the other hand, the embodiment of the application also provides a steam box which comprises the evaporation tray.

The steam box further comprises a controller, the controller is electrically connected with the capacitance detection mechanism 2, a first capacitance value of the evaporation tray during dry burning is prestored in the controller, the controller is further used for obtaining the capacitance value detected by the capacitance detection mechanism 2 in real time and comparing the capacitance value with the first capacitance value to judge whether the evaporation tray is in a dry burning state, and the controller is further used for controlling the evaporation tray to stop heating when the evaporation tray is in the dry burning state.

The controller in the steam box can be RSZG-200, the beauty control DT778-122-30L, SF-550W3, SF-550T1 and the like, and can also be other existing controller types.

In the embodiment of the application, the controller is respectively electrically connected with the capacitance detection mechanism 2 and the heating structure 4, and the capacitance detection mechanism 2 detects capacitance values of liquid in the evaporation pan body 1 at different heights in real time and transmits the detected capacitance values to the controller in real time. The controller pre-stores a first capacitance value of the evaporation tray during dry burning, namely when the capacitance value corresponding to the evaporated liquid in the evaporation tray is the first capacitance value, the controller compares the capacitance value detected by the capacitance sensor 21 with the pre-stored first capacitance value to judge whether the current evaporation tray is in a dry burning state. If the capacitance value received by the controller meets the pre-stored first capacitance value, the evaporation tray is in a dry-burning state at the moment, and the controller controls the heating structure 4 to stop heating the evaporation tray, so that the evaporation tray can be prevented from being broken due to serious dry burning. In order to avoid dry heating of the evaporation pan, the heating of the evaporation pan may be stopped when the capacitance detected in real time approaches the first capacitance.

In the embodiment of the application, the steam box further comprises an alarm device, wherein the alarm device is electrically connected with the controller and is used for giving an alarm when the evaporation pan is in a dry-burning state.

Specifically, the alarm device in the steam box is electrically connected with the controller, and when the controller receives the capacitance value detected by the capacitance detection mechanism 2 in real time, the capacitance value is compared with a pre-stored first capacitance value. If the detected capacitance value is close to the first capacitance value, the controller controls the alarm device to give an alarm, so that a user is reminded of paying attention to the current state of the evaporation tray, water is timely added or power is off, and breakage caused by excessive dry burning of the evaporation tray is prevented.

In the embodiment of the application, the steam box further comprises a display, the display is electrically connected with the controller, and the controller is pre-stored with capacitance values corresponding to different liquid levels of the liquid in the evaporating pan, namely, in different liquid level states, only one capacitance value corresponding to the state is provided. Because the evaporating pan is heated, the liquid in the pan is evaporated, the liquid level can be gradually reduced, and when the capacitance detection mechanism 2 detects the current capacitance value in real time, the liquid level height value corresponding to the capacitance value can be found out from the data prestored in the controller, and the current liquid level height is displayed in real time through the display.

For example, assuming that the capacitance value corresponding to the initial height of the liquid level is B, the liquid level height corresponding to the pre-stored capacitance value in the controller is 2cm, the liquid level height displayed by the display is 2cm, after heating for a period of time, the capacitance detected by the capacitance detection mechanism 2 is a, and if the capacitance value pre-stored in the controller is 1cm, the liquid level height of the evaporation pan is displayed by the final display as 1cm.
