Technical Field
[0001] The utility model relates to the technical field of air purification, in particular to an electric heating humidifier with multiple protections. Background Art
[0002] In the field of air purification in the semiconductor industry, the use environment requirements for some high-precision semiconductor equipment are very stringent. In addition to filtering particulate matter in the air, the local air humidity must also be controlled. Humidity control includes dehumidification and humidification, and the humidification work is generally done by a humidifier.
[0003] Existing humidifiers generally include atomizing humidifiers and electrothermal humidifiers. Electrothermal humidifiers often have water leakage problems during operation. Water leakage will cause the humidifier to malfunction. When a malfunction occurs, the humidifier needs to be repaired. During the maintenance of the humidifier, because the humidification part is an indispensable part of the semiconductor equipment in daily operation, the semiconductor equipment has to be shut down for the maintenance of the humidifier, and this downtime will cause immeasurable economic losses. Utility Model Content
[0004] The purpose of the utility model is to provide an electric heating humidifier with multiple protections to solve the problems raised in the above background technology.

[0006] Furthermore, an overflow pipe is provided at the top end of the side wall of the shell.

[0008] Furthermore, a water collection tray is provided below the shell.
[0009] Furthermore, a drainage pipe is provided at the bottom end of the inner wall of the water collection tray.
[0010] Furthermore, a plurality of brackets are provided at the bottom of the shell.
[0011] Furthermore, a lower liquid level sensor electrically connected to the central control unit is provided on the upper portion of the inner wall of the shell below the upper liquid level sensor, and the position of the lower liquid level sensor is higher than the connection between the heating tube and the shell.

[0014] The beneficial effects achieved by the utility model are:
[0015] 1. The float valve is set to control the switch of the water inlet to avoid water leakage. At the same time, the upper liquid level sensor, central control unit and water inlet solenoid valve are added to avoid water leakage caused by the failure of the float valve to close the water inlet in time. The overflow pipe is set to avoid water leakage caused by the failure of the float valve and the upper liquid level sensor. At the same time, the water accumulation tray and drain pipe are set to facilitate the collection of water discharged from the overflow pipe and discharge it to the sewer;
[0016] 2. By setting the lower liquid level sensor at a position higher than the heating tube, the phenomenon of the heating tube drying out can be avoided. Furthermore, by setting a temperature detector to detect the temperature around the heating tube, the failure of the lower liquid level sensor can be avoided, which may cause the heating tube to dry out.
[0017] 3. The central control unit controls the discharge solenoid valve to open regularly, which is convenient for cleaning the scale in the shell. BRIEF DESCRIPTION OF THE DRAWINGS
[0018] Figure 1 It is a structural schematic diagram of an electric heating humidifier with multiple protections in an embodiment. DETAILED DESCRIPTION
[0019] The utility model is further described below in conjunction with the accompanying drawings.
[0020] like Figure 1 As shown, the utility model discloses an electric humidifier with multiple protections, comprising: a shell 1, a steam port 2 is arranged at the top of the shell 1, a water inlet 3 connected to an external water inlet pipeline is arranged on the side wall of the shell 1, a heating tube 4 is arranged in the shell 1 below the water inlet 3, and a float valve 5 is arranged at the output end of the water inlet 3.
[0021] Based on the above structure, Figure 1As shown, when in use, the external water source is transported into the shell body 1 through the water inlet pipeline, the water inlet 3 and the float valve 5 in sequence, and the water level in the shell body 1 continues to rise accordingly, and the float end of the float valve 5 continues to rise along with the water level, and the valve end of the float valve 5 continues to narrow the channel in the float valve 5 as the float end continues to rise, until the channel in the float valve 5 is completely closed, and the heating tube 4 heats the water in the shell body 1 until it boils, and the water vapor is discharged through the steam port 2. As the water continues to vaporize, the water level in the shell body 1 will also drop accordingly, and the float end of the float valve 5 drops along with the water level, and the valve end of the float valve 5 reopens the channel in the float valve 5 as the float end drops, thereby replenishing the water in the shell body 1 until the channel in the float valve 5 is closed again, and the cycle can be repeated.
[0022] Further, such as Figure 1 As shown, in order to avoid water leakage caused by failure of the float valve, an overflow pipe 6 is connected to the top of the side wall of the shell 1. When the float valve 6 fails, excess water in the shell 1 is discharged through the overflow pipe 6.
[0023] Further, such as Figure 1 As shown, in order to prevent the failure of the float valve causing water to continue to leak out from the overflow pipe 6, an upper liquid level sensor 7 is arranged on the inner wall of the shell 1. The position of the upper liquid level sensor 7 is lower than the connection between the overflow pipe 6 and the shell 1. An inlet solenoid valve 8 is arranged on the external water inlet pipeline. A central control unit electrically connected to the float valve 5 and the inlet solenoid valve 8 is arranged on the top of the shell 1. When the float valve 6 fails, the water level in the shell 1 continues to rise, thereby triggering the upper liquid level sensor 7. The upper liquid level sensor 7 feeds back information to the central control unit, and the central control unit closes the inlet solenoid valve 8.
[0024] Further, such as Figure 1 As shown, in order to prevent the water discharged from the overflow pipe from flowing freely to the ground and affecting the surrounding equipment, a water collection pan 9 is provided under the shell 1, and the output end of the overflow pipe 6 is provided in the water collection pan 9, and the water discharged from the overflow pipe 6 is accumulated in the water collection pan 9.
[0025] Further, such as Figure 1 As shown, in order to prevent water from overflowing from the water collection tray after the water collection tray is filled with water, a drain pipe 91 is provided at the bottom end of the inner wall of the water collection tray 9, and the drain pipe 91 is used to discharge water to the sewer.
[0026] Further, such as Figure 1 As shown, in order to prevent the shell from occupying the capacity of the water collection tray and to facilitate smooth drainage of the water collection tray, a plurality of brackets are provided at the bottom of the shell 1.
[0027] Further, such as Figure 1As shown, in order to prevent the water level in the shell from being too low, which may cause the heating tube to burn dry, a lower liquid level sensor 10 electrically connected to the central control unit is provided on the upper part of the inner wall of the shell 1 below the upper liquid level sensor 7. The position of the lower liquid level sensor 10 is higher than the connection between the heating tube 4 and the shell 1. When the water level in the shell 1 continues to drop until the lower liquid level sensor 10 is triggered, the lower liquid level sensor 10 feeds back information to the central control unit, and the central control unit opens the water inlet solenoid valve 8, and the external water inlet pipeline transports water into the shell 1, thereby replenishing the water in the shell 1.
[0028] Further, such as Figure 1 As shown, in order to avoid failure of the lower liquid level sensors, which would cause the heating tube to dry out, a temperature detector 11 electrically connected to the central control unit is provided on the inner wall of the shell 1 between the heating tube 4 and the water inlet 3. When the heating tube 4 does not stop working but continues to heat due to the low water level in the shell 1, the surface temperature of the heating tube will continue to rise. When the temperature detector 12 senses that the ambient temperature of the heating tube 4 exceeds 105°, the information is fed back to the central control unit. The central control unit opens the water inlet solenoid valve 8, and the external water inlet pipeline transports water into the shell 1, thereby replenishing the water in the shell 1.
[0029] Further, such as Figure 1 As shown, in order to facilitate the cleaning of scale in the shell, a drain port 12 connected to an external drain pipeline is provided on the side wall of the shell 1 below the heating tube 4, and a drain solenoid valve 13 electrically connected to the central control unit is provided on the external drain pipeline. The central control unit periodically opens the drain solenoid valve 13 to discharge the scale in the shell 1 from the drain port 12 and the external drain pipeline in turn.
[0030] The float valve used in the present invention is already a prior art and will not be described in detail here.
[0031] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
