Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] Please see Figure 1-4 The present invention provides the following technical solution: a steam heating device with automatic water temperature control, comprising a temperature-controlled heating box assembly 1, a tap water inlet 8 fixedly installed on one side of the temperature-controlled heating box assembly 1, an inlet pipe 4 provided on the side of the tap water inlet 8 away from the temperature-controlled heating box assembly 1, a second valve 3 fixedly installed near the center of the inlet pipe 4, a steam output pipe 7 fixedly installed on the side of the temperature-controlled heating box assembly 1 away from the tap water inlet 8, and multiple support legs 5 provided below the temperature-controlled heating box assembly 1. The tap water inlet 8 and the inlet pipe 4 are connected by a filter pumping device 2, and the temperature-controlled heating box assembly 1 and the multiple support legs 5 are connected by an auxiliary dehumidification device 6.

[0022] Specifically, the filtration and pumping device 2 includes a connecting box 21, a connecting pipe 22, a pumping assembly 23, a filter screen 24, a screw 25, and a threaded cap 26. The connecting box 21 is fixedly installed on the side of the tap water inlet 8 near the water inlet pipe 4. The connecting box 21 is connected to the water inlet pipe 4 through the connecting pipe 22. The screw 25 is threadedly installed on the top of the connecting box 21. The filter screen 24 is installed on the bottom of the screw 25 and inside the connecting box 21 through a bearing. The threaded cap 26 is threadedly installed on the top of the connecting box 21 and on the side of the screw 25. The pumping assembly 23 is fixedly installed below the connecting pipe 22.

[0023] By adopting the above technical solution, staff can filter the water that is about to enter the temperature-controlled heating box assembly 1 when needed through the cooperation of the filter screen 24 and the connecting box 21, thereby reducing the possibility of adverse effects on the temperature-controlled heating box assembly 1.

[0024] Specifically, the inner side of the connecting box 21 is in contact with one side of the filter plate 24.

[0025] By adopting the above technical solution, the device can limit the lifting and lowering of the filter plate 24 through the connecting box 21, thereby preventing the filter plate 24 from shifting during the lifting and lowering process and ensuring normal operation.

[0026] Specifically, the pumping assembly 23 also includes a first valve 231, a water supply pipe 232, a pump body 233, and a first hose 234. The water supply pipe 232 is fixedly installed below the connecting pipe 22, and the first hose 234 is provided below the water supply pipe 232. The water supply pipe 232 and the first hose 234 are connected through the pump body 233. The first valve 231 is fixedly installed near the center of the water supply pipe 232.

[0027] By adopting the above technical solution, the device can actively draw water from the outside when needed through the cooperation of the pump body 233 and the first hose 234, thereby better meeting the working needs in different situations.

[0028] In this embodiment, when the device is needed for steam heating, the operator connects the inlet pipe 4 to the water supply pipe and the steam output pipe 7 to the steam delivery pipe. The heating temperature of the temperature-controlled heating box assembly 1 is adjusted. If water filtration is required, the screw 25 in the filter pump 2 is rotated. The screw 25 is threadedly connected to the connecting box 21, and the screw 25 is bearing-connected to the filter screen plate 24. The inner side of the connecting box 21 and one side of the filter screen plate 24 are in contact with each other. Therefore, the screw 25 drives the filter screen plate 24 to descend until it blocks the tap water inlet 8. Then, the second valve 3 is opened, and water passes through the inlet pipe 4 and the connecting pipe 22 into the connecting box 21. After being filtered by the filter plate 24, the water then passes through the tap water inlet 8 and enters the temperature control heating box assembly 1. The temperature control heating box assembly 1 automatically heats the water, and then the steam is discharged through the steam output pipe 7, thus enabling the device to operate. If the device needs to actively pump water, the operator closes the second valve 3, sends the end of the first hose 234 in the pumping assembly 23 to the water source, then opens the first valve 231, and starts the pump body 233. Under the action of the pump body 233, the water passes through the first hose 234, the pump body 233, and the water supply pipe 232 into the connecting pipe 22, thus enabling active water pumping. The support leg 5 provides support. When needed, the operator can unscrew the threaded cover 26 to clean the inside of the connecting box 21.

[0029] Example 2

[0030] The difference between this embodiment and embodiment 1 is that the auxiliary dehumidification device 6 includes a base box 61, a fan 62, a second flexible hose 63, a fixing net 64, an air outlet net 65, and silica gel desiccant 66. The temperature-controlled heating box assembly 1 is connected to the multiple support legs 5 through the base box 61. The fan 62 is fixedly installed on one side of the base box 61. The second flexible hose 63 is fixedly installed on the side of the fan 62 away from the base box 61. The fixing net 64 is fixedly installed on the inside of the base box 61. The inside of the base box 61 and the position on the side of the fixing net 64 away from the fan 62 is filled with silica gel desiccant 66. The air outlet net 65 is fixedly installed at the bottom of the base box 61.

[0031] By adopting the above technical solution, staff can use the combination of the fan 62 and silica gel desiccant 66 to dehumidify the surrounding areas that are damp due to work or other reasons when needed, thereby reducing the possibility of discomfort to the surrounding personnel.

[0032] Specifically, the auxiliary dehumidification device 6 also includes a blocking block 67, which is threadedly installed on the side of the bottom box 61 away from the fan 62.

[0033] By adopting the above technical solution, staff can unscrew the block 67 to replace the silica gel desiccant 66 when needed, thereby reducing the difficulty of replacing the silica gel desiccant 66 and alleviating the workload of staff.

[0034] In this embodiment, if a certain area is damp due to work or other reasons, the staff can align the second hose 63 in the auxiliary dehumidification device 6 with the damp location and start the fan 62. Under the action of the fan 62, the moisture in the damp location passes through the second hose 63 and the fan 62 with the airflow and enters the bottom box 61. Then, the moisture is absorbed by the silica gel desiccant 66 on one side of the fixing net 64, and the airflow passes through the air outlet net 65 to be discharged, thereby improving the surrounding environment and reducing the possibility of discomfort to the surrounding people. When necessary, the staff can unscrew the block 67 to replace the silica gel desiccant 66.

[0035] The structure and principle of the temperature-controlled heating box assembly 1 (comprising a heating box body, wires, heating resistance wires, and a temperature display panel), the steam output pipe 7, and the tap water input terminal 8 in this utility model have been disclosed in the electric steam heating box disclosed in Chinese patent application number 201420618182.4. Its working principle is to generate steam by electric heating, avoiding the use of natural gas. The installation and laying of natural gas pipelines alone saves a considerable amount of expenses and eliminates the safety hazards brought by natural gas pipelines. Furthermore, the electric steam heating box can accurately control the temperature of the steam and output a comparative temperature, making it safe and reliable.

[0036] The working principle and usage process of this utility model are as follows: When the device is needed for steam heating, the operator connects the inlet pipe 4 to the water supply pipe and the steam output pipe 7 to the steam delivery pipe. The heating temperature of the temperature-controlled heating box assembly 1 is adjusted. If water filtration is required, the screw 25 in the filter pumping device 2 is rotated. The screw 25 is threadedly connected to the connecting box 21, and the screw 25 is bearing-connected to the filter screen plate 24. The inner side of the connecting box 21 and one side of the filter screen plate 24 are in contact with each other, so the screw 25 drives the filter screen plate 24 to descend until it blocks the tap water inlet 8. Then, the second valve 3 is opened, and water passes through the inlet pipe 4 and connecting pipe 22 into the connecting box 21, where it is filtered by the filter screen plate 24. The water then passes through the tap water inlet 8 into the temperature-controlled heating box assembly 1, which automatically heats the water. Steam is then discharged through the steam output pipe 7, thus commencing operation. If the device needs to actively pump water, the operator... The operator closes the second valve 3, sends the end of the first hose 234 in the water pumping assembly 23 to the water source, then opens the first valve 231, and starts the pump body 233. Under the action of the pump body 233, water passes through the first hose 234, the pump body 233, and the water supply pipe 232 into the connecting pipe 22, thereby actively pumping water. The support leg 5 provides support. When needed, the operator can unscrew the threaded cap 26 to clean the inside of the connecting box 21. If a certain place in the surrounding area is damp due to work or other reasons, the operator can align the second hose 63 in the auxiliary dehumidification device 6 with the damp location and start the fan 62. Under the action of the fan 62, the moisture in the damp location passes through the second hose 63 and the fan 62 with the airflow and enters the bottom box 61. Then the moisture is absorbed by the silica gel desiccant 66 on one side of the fixed net 64, while the airflow passes through the air outlet net 65 and is discharged, thereby improving the surrounding environment and reducing the possibility of discomfort for the surrounding personnel. When needed, the operator can unscrew the block 67 to replace the silica gel desiccant 66.
